date be later than the date thirty days following the initial advance of such
Swingline Loan.

         2.2  Method of Borrowing.

         (a)  Notice of Request for Extensions of Credit.  The Borrower shall
request an Extension of Credit hereunder as follows:

              (i)    Revolving Loans. In the case of Revolving Loans, by
         delivery of a Notice of Borrowing (or telephonic notice or email
         notice, in each case promptly confirmed in writing) to the
         Administrative Agent not later than 11:00 A.M. (Charlotte, North
         Carolina time) on the Business Day prior to the date of the requested
         borrowing. Each such notice shall be irrevocable and shall specify (A)
         that a Revolving Loan is requested, (B) the date of the requested
         borrowing (which shall be a Business Day) and (C) the aggregate
         principal amount to be borrowed. The Administrative Agent shall give
         notice to each Lender promptly upon receipt of any such notice, the
         contents thereof and such Lender's share of any borrowing to be made
         pursuant thereto.

              (ii)   Letters of Credit. In the case of Letters of Credit, by
         delivery of a Notice of Request for Letter of Credit to the Issuing
         Lender (with a copy to the Administrative Agent) not later than 11:00
         A.M. (Charlotte, North Carolina time) on the third Business Day prior
         to the date of the requested issuance or extension (or such shorter
         period as may be agreed by the Issuing Lender). Each such notice shall
         be irrevocable and shall specify, among other things, (A) that a
         Letter of Credit is requested, (B) the date of the requested issuance
         or extension, (C) the type, amount, expiry date and terms on which
         such Letter of Credit is to be issued or extended, (D) the beneficiary
         and (E) the purpose of such Letter of Credit.

              (iii)  Swingline Loans. In the case of Swingline Loans, by
         delivery of a Notice of Borrowing (or telephonic notice or email
         notice, in each case promptly confirmed in writing) to the Swingline
         Lender (with a copy to the Administrative Agent) not later than 11:00
         A.M. (Charlotte, North Carolina time) on the Business Day of the
         requested borrowing. Each such notice shall be irrevocable and shall
         specify (A) that a Swingline Loan is requested, (B) the date of the
         requested borrowing (which shall be a Business Day) and (C) the
         aggregate principal amount to be borrowed. Notwithstanding the
         foregoing, in the event that an "auto borrow" or "zero balance" or
         similar arrangement shall then be in place with the Swingline Lender,
         the Borrower shall request Swingline Loans pursuant to such
         alternative notice arrangements, if any, provided thereunder or in
         connection therewith.

         (b)  Minimum Amounts. Each Revolving Loan shall be in a minimum
principal amount of $100,000 (or, if less, the remaining Aggregate Revolving
Loan Committed Amount) and in integral multiples of $50,000 in excess thereof.
Each Swingline Loan shall be in a minimum principal amount of $10,000 (or, if
less, the remaining Swingline Committed Amount) and in integral multiples of
$10,000 in excess thereof: provided that in the event that an "auto borrow" or
"zero balance" or similar arrangement

                                       23
<PAGE>
shall then be in place with the Swingline Lender, each Swingline Loan shall be
in such minimum amounts, if any, provided by such agreement.

         2.3  Type of Loans; Interest.

         Revolving Loans and Swingline Loans shall be made as Prime Rate Loans.
Subject to Section 3.1, the Loans shall bear interest at a per annum rate,
payable in arrears on the last day of each calendar month (or at such other
times as may be specified herein), equal to the Adjusted Prime Rate.

         2.4  Repayment.

         The principal amount of all Loans (together with all accrued interest
thereon) shall be due and payable in full on the Termination Date.

         2.5  Notes.

         The Loans shall be evidenced by the Revolving Notes.

         2.6  Additional Provisions relating to Letters of Credit.

         (a)  Generally. If any Letter of Credit issued hereunder shall have an
expiry date, whether as originally issued or by extension, extending beyond the
Termination Date, the Borrower shall, on the Termination Date, either (i) cause
such Letter of Credit to be surrendered to the Issuing Lender, (ii) provide to
the Issuing Lender a back-to-back letter of credit in respect thereof
reasonably satisfactory to the Issuing Lender or (iii) provide cash collateral
to the Issuing Lender in an amount equal to the maximum amount available to be
drawn under such Letter of Credit. Each Letter of Credit shall comply with the
related LOC Documents. The issuance date of each Letter of Credit shall be a
Business Day.

         (b)  Reports. The Issuing Lender will provide to the Administrative
Agent at least monthly, and more frequently upon request, a detailed summary
report on each Letter of Credit and the activity thereon, in form and substance
acceptable to the Administrative Agent. In addition, the Issuing Lender will
provide to the Administrative Agent for dissemination to the Lenders at least
quarterly, and more frequently upon request, a detailed summary report on each
Letter of Credit issued by the Issuing Lender and the activity thereon,
including, among other things, the Credit Party for whose account such Letter
of Credit is issued, the beneficiary, the face amount, the expiry date and the
purpose (as provided by the Borrower). The Issuing Lender will provide copies
of each Letter of Credit to the Administrative Agent and the Lenders promptly
upon request.

         (c)  Participation. Upon issuance of a Letter of Credit, each Lender
shall be deemed to have purchased without recourse a risk participation from
the Issuing Lender in such Letter of Credit and the obligations arising
thereunder, in each case in an amount equal to its Revolving Commitment
Percentage of the obligations under such Letter of Credit and shall absolutely,
unconditionally and irrevocably assume, as primary obligor and not as surety,
and be obligated to pay to the Issuing Lender and discharge when due, its
Revolving Commitment Percentage of the obligations arising under such Letter of
Credit. Without limiting the scope and nature of each Lender's participation in
any Letter of Credit, to the extent that the Issuing Lender has not been
reimbursed as required hereunder or under any such Letter of Credit, each
Lender shall pay to the Issuing Lender its pro rata share of such unreimbursed
drawing in same day funds on the day of notification by the Issuing Lender of
an unreimbursed drawing pursuant to the provisions of subsection (d) hereof.
The obligation of each Lender to so reimburse the Issuing Lender shall be
absolute and unconditional and shall not be affected by the

                                       24
<PAGE>
occurrence of a Default, an Event of Default or any other occurrence or event.
Any such reimbursement shall not relieve or otherwise impair the obligation of
the Borrower to reimburse the Issuing Lender under any Letter of Credit,
together with interest as hereinafter provided.

         (d)  Reimbursement. In the event of any drawing under any Letter of
Credit, the Issuing Lender will promptly notify the Borrower. Unless the
Borrower shall immediately notify the Issuing Lender that it intends to
otherwise reimburse the Issuing Lender for such drawing, the Borrower shall be
deemed to have requested that the Lenders make a Revolving Loan in the amount
of the drawing as provided in subsection (e) below on the related Letter of
Credit, the proceeds of which will be used to satisfy the related reimbursement
obligations. The Borrower promises to reimburse the Issuing Lender on the day
of drawing under any Letter of Credit (either with the proceeds of a Revolving
Loan obtained hereunder or otherwise) in same day funds. If the Borrower shall
fail to reimburse the Issuing Lender as provided hereinabove, the unreimbursed
amount of such drawing shall bear interest at a per annum rate equal to the sum
of the Adjusted Prime Rate and two percent (2%). The Borrower's reimbursement
obligations hereunder shall be absolute and unconditional under all
circumstances irrespective of any rights of setoff, counterclaim or defense to
payment the Borrower may claim or have against the Issuing Lender, the Agents,
the Lenders, the beneficiary of the Letter of Credit drawn upon or any other
Person, including, without limitation, any defense based on any failure of the
Borrower or any other Credit Party to receive consideration or the legality,
validity, regularity or unenforceability of the Letter of Credit. The Issuing
Lender will promptly notify the Lenders of the amount of any unreimbursed
drawing and each Lender shall promptly pay to the Administrative Agent for the
account of the Issuing Lender in Dollars and in immediately available funds,
the amount of such Lender's Revolving Commitment Percentage of such
unreimbursed drawing. Such payment shall be made on the day such notice is
received by the Lenders from the Issuing Lender if such notice is received at
or before 2:00P.M. (Charlotte, North Carolina time) otherwise such payment
shall be made at or before 12:00 Noon (Charlotte, North Carolina time) on the
Business Day next succeeding the day such notice is received. If any Lender
does not pay such amount to the Issuing Lender in full upon such request, such
Lender shall, on demand, pay to the Administrative Agent for the account of the
Issuing Lender interest on the unpaid amount during the period from the date of
such drawing until such Lender pays such amount to the Issuing Lender in full
at a rate per annum equal to, if paid within two (2) Business Days of the date
that such Lender is required to make payments of such amount pursuant to the
preceding sentence, the Federal Funds Rate and thereafter at a rate equal to
the Prime Rate. Each Lender's obligation to make such payment to the Issuing
Lender, and the right of the Issuing Lender to receive the same, shall be
absolute and unconditional, shall not be affected by any circumstance
whatsoever and without regard to the termination of this Agreement or the
Commitments hereunder, the existence of a Default or Event of Default or the
acceleration of the obligations of the Borrower hereunder and shall be made
without any offset, abatement, withholding or reduction whatsoever.
Simultaneously with the making of each such payment by a Lender to the Issuing
Lender, such Lender shall, automatically and without any further action on the
part of the Issuing Lender or such Lender, acquire a participation in an amount
equal to such payment (excluding the portion of such payment constituting
interest owing to the Issuing Lender) in the related unreimbursed drawing
portion of the LOC Obligation and in the interest thereon and in the related
LOC Documents, and shall have a claim against the Borrower with respect thereto.

         (e)  Repayment with Revolving Loans. On any day on which the Borrower
shall have requested, or been deemed to have requested, a Revolving Loan
advance to reimburse a drawing under a Letter of Credit pursuant to clause (d)
above, the Administrative Agent shall give notice to the Lenders that a
Revolving Loan has been requested or deemed requested by the Borrower to be
made in connection with a drawing under a Letter of Credit, in which case a
Revolving Loan shall be immediately made to the Borrower by all such Lenders
(notwithstanding any termination of the Commitments pursuant to Section 10.2)
pro rata based on their respective Revolving Commitment Percentages (determined
before giving effect to any termination of the Commitments pursuant to Section
10.2) and the proceeds thereof shall be paid directly to the Issuing Lender for

                                       25
<PAGE>
application to the respective LOC Obligations. Each Lender hereby irrevocably
agrees to make its pro rata share of each such Revolving Loan immediately upon
any such request or deemed request in the amount, in the manner and on the date
specified in the preceding sentence notwithstanding (i) the amount of such
borrowing may not comply with the minimum amount for advances of Revolving
Loans otherwise required hereunder, (ii) whether any conditions specified in
Section 5.2 are then satisfied, (iii) whether a Default or an Event of Default
then exists, (iv) failure for any such request or deemed request for such
Revolving Loan to be made by the time otherwise required hereunder, (v) whether
the date of such borrowing is a date on which Revolving Loans are otherwise
permitted to be made hereunder or (vi) any termination of the Commitments
relating thereto immediately prior to or contemporaneously with such borrowing.
In the event that any Revolving Loan cannot for any reason be made on the date
otherwise required above, then each Lender hereby agrees that it shall
forthwith purchase (as of the date such borrowing would otherwise have
occurred, but adjusted for any payments received from the Borrower on or after
such date and prior to such purchase) from the Issuing Lender such
participation in the outstanding LOC Obligations related to the applicable
Letter of Credit as shall be necessary to cause each Lender to share in such
LOC Obligations ratably (based upon their respective Revolving Commitment
Percentages (determined before giving effect to any termination of the
Commitments pursuant to Section 10.2)); provided that in the event such payment
is not made by any Lender on the day of drawing, such Lender shall pay to the
Issuing Lender interest on the amount of its unfunded Participation Interest at
a rate equal to, if paid within two (2) Business Days of the date of drawing,
the Federal Funds Rate, and thereafter at the Prime Rate.

         (f)  Designation of other Credit Parties as Account Parties.
Notwithstanding anything to the contrary set forth in this Agreement, a Letter
of Credit issued hereunder may contain a statement to the effect that such
Letter of Credit is issued for the account of a Guarantor, provided that, in
each case notwithstanding such statement, the Borrower shall be the actual
account party for all purposes of this Agreement for such Letter of Credit and
such statement shall not affect the Borrower's reimbursement obligations
hereunder with respect to such Letter of Credit.

         (g)  Renewal, Extension.  The renewal or extension of any Letter of
Credit shall, for purposes hereof, be treated in all respects the same as the
issuance of a new Letter of Credit hereunder.

         (h)  Applicability of ISP98 and UCP. Unless otherwise expressly agreed
by the Issuing Lender and the Borrower when a Letter of Credit is issued, (i)
the rules of the "International Standby Practices 1998" published by the
Institute of International Banking Law & Practice (or such later version
thereof as may be in effect at the time of issuance) shall apply to each
standby Letter of Credit, and (ii) the rules of the Uniform Customs and
Practice for Documentary Credits, as most recently published by the
International Chamber of Commerce (the "ICC") at the time of issuance
(including the ICC decision published by the Commission on Banking Technique
and Practice on April 6, 1998 regarding the European single currency (euro))
shall apply to each Letter of Credit.

         (i)  Indemnification; Nature of Issuing Lender's Duties.

              (i)    In addition to its other obligations under this Section
         2.6, the Borrower hereby agrees to protect, indemnify, pay and save the
         Issuing Lender harmless from and against any and all claims, demands,
         liabilities, damages, losses, costs, charges and expenses (including
         reasonable attorneys' fees) that the Issuing Lender may incur or be
         subject to as a consequence, direct or indirect, of (A) the issuance
         of any Letter of Credit or (B) the failure of the Issuing Lender to
         honor a drawing under a Letter of Credit as a result of any act or
         omission, whether rightful or wrongful, of any present or future de
         jure or de facto government or governmental authority (all such acts
         or omissions, herein called "Government Acts").

                                       26
<PAGE>
              (ii)   As between the Borrower and the Issuing Lender, the
         Borrower shall assume all risks of the acts, omissions or misuse of any
         Letter of Credit by the beneficiary thereof. The Issuing Lender shall
         not be responsible: (A) for the form, validity, sufficiency, accuracy,
         genuineness or legal effect of any document submitted by any party in
         connection with the application for and issuance of any Letter of
         Credit, even if it should in fact prove to be in any or all respects
         invalid, insufficient, inaccurate, fraudulent or forged; (B) for the
         validity or sufficiency of any instrument transferring or assigning or
         purporting to transfer or assign any Letter of Credit or the rights or
         benefits thereunder or proceeds thereof, in whole or in part, that may
         prove to be invalid or ineffective for any reason; (C) for errors,
         omissions, interruptions or delays in transmission or delivery of any
         messages, by mail, cable, telegraph, telex or otherwise, whether or not
         they be in cipher; (D) for any loss or delay in the transmission or
         otherwise of any document required in order to make a drawing under a
         Letter of Credit or of the proceeds thereof; and (E) for any
         consequences arising from causes beyond the control of the Issuing
         Lender, including, without limitation, any Government Acts. None of the
         above shall affect, impair, or prevent the vesting of the Issuing
         Lender's rights or powers hereunder.

              (iii)  In furtherance and extension and not in limitation of
         the specific provisions hereinabove set forth, any action taken or
         omitted by the Issuing Lender, under or in connection with any Letter
         of Credit or the related certificates, if taken or omitted in good
         faith, shall not put the Issuing Lender under any resulting liability
         to the Borrower or any other Credit Party. It is the intention of the
         parties that this Agreement shall be construed and applied to protect
         and indemnify the Issuing Lender against any and all risks involved in
         the issuance of the Letters of Credit, all of which risks are hereby
         assumed by the Borrower (on behalf of itself and each of the other
         Credit Parties), including, without limitation, any and all Government
         Acts. The Issuing Lender shall not in any way be liable for any failure
         by the Issuing Lender or anyone else to pay any drawing under any
         Letter of Credit as a result of any Government Acts or any other cause
         beyond the control of the Issuing Lender.

              (iv)   Nothing in this subsection (i) is intended to limit the
         reimbursement obligations of the Borrower contained in subsection (d)
         above. The obligations of the Borrower under this subsection (i) shall
         survive the termination of this Agreement. No act or omissions of any
         current or prior beneficiary of a Letter of Credit shall in any way
         affect or impair the rights of the Issuing Lender to enforce any right,
         power or benefit under this Agreement.

              (v)    Notwithstanding anything to the contrary contained in this
         subsection (i), the Borrower shall have no obligation to indemnify
         the Issuing Lender in respect of any liability incurred by the
         Issuing Lender (A) arising out of the gross negligence or willful
         misconduct of the Issuing Lender, as determined by a court of
         competent jurisdiction, or (B) caused by the Issuing Lender's failure
         to pay under any Letter of Credit after presentation to it of a
         request strictly complying with the terms and conditions of such
         Letter of Credit, as determined by a court of competent jurisdiction,
         unless such payment is prohibited by any law, regulation, court order
         or decree.

         (j)  Responsibility of Issuing Lender. It is expressly understood
and agreed that the obligations of the Issuing Lender hereunder to the Lenders
are only those expressly set forth in this Agreement and that the Issuing
Lender shall be entitled to assume that the conditions precedent set forth in
Section 5.2 have been satisfied unless it shall have acquired actual knowledge
that any such condition precedent has not been satisfied; provided, however,
that nothing set forth in this Section 2.6 shall be deemed to prejudice the
right of any Lender to recover from the Issuing Lender any amounts made
available by such Lender to the Issuing Lender pursuant to this Section 2.6 in
the event that it is determined by a court of competent jurisdiction that the
payment with

                                       27
<PAGE>
respect to the relevant Letter of Credit constituted gross negligence or
willful misconduct on the part of the Issuing Lender.

         (k)  Limitation on Obligation of the Issuing Lender.
Notwithstanding anything contained herein to the contrary, the Issuing Lender
shall not be under any obligation to issue, renew or extend any Letter of
Credit if (i) any order, judgment or decree of any Governmental Authority or
arbitrator shall by its terms purport to enjoin or restrain the Issuing Lender
from issuing such Letter of Credit, or any applicable law, rule or regulation
or any request or directive (whether or not having the force of law) from any
Governmental Authority with jurisdiction over the Issuing Lender shall
prohibit, or request that the Issuing Lender refrain from, the issuance of
letters of credit generally or such Letter of Credit in particular, or shall
impose upon the Issuing Bank with respect to such Letter of Credit any
restriction, reserve or capital requirement (for which the Issuing Lender is
not otherwise compensated hereunder) not in effect on the Closing Date, or
shall impose upon the Issuing Lender any unreimbursed loss, costs or expense
which was not applicable on the Closing Date and which the Issuing Lender
should deem material to it in good faith, or (ii) the issuance, renewal or
extension would violate or otherwise contravene its internal policy.

         (l)  Conflict with LOC Documents. Solely as among the parties
 hereto, in the event of any conflict between this Agreement and any LOC
Document (including any letter of credit application), this Agreement shall
control.

         (m)  Letters of Credit Under Existing Credit Agreement. As
 provided in the Supplemental DIP Financing Order, any Letters of Credit issued
under the Existing Credit Agreement and outstanding on the Closing Date shall
be deemed to be Letters of Credit requested by the Borrower and issued by the
Issuing Lender hereunder.

         2.7      Additional Provisions relating to Swingline Loans.

         The Swingline Lender may, at any time, in its sole discretion, by
written notice to the Borrower and the Lenders, demand repayment of any
Swingline Loan by way of a Revolving Loan, in which case the Borrower shall be
deemed to have requested such Revolving Loan in the amount of such Swingline
Loan; provided, however, that any such demand shall be deemed to have been
given one Business Day prior to the Termination Date, on the date of the
occurrence of any Event of Default and upon acceleration of the indebtedness
hereunder and the exercise of remedies in accordance with the provisions of
Section 10.2. Each Lender hereby irrevocably agrees to make its Revolving
Commitment Percentage of such Revolving Loan in the amount, in the manner and
on the date specified in the preceding sentence notwithstanding (i) the amount
of such borrowing may not comply with the minimum amount for advances of
Revolving Loans otherwise required hereunder, (ii) whether any conditions
specified in Section 5.2 are then satisfied, (iii) whether a Default or an
Event of Default then exists, (iv) failure of any such request or deemed
request for such Revolving Loan to be made by the time otherwise required
hereunder, (v) whether the date of such borrowing is a date on which Revolving
Loans are otherwise permitted to be made hereunder or (vi) any termination of
the Commitments relating thereto prior to or contemporaneously with such
borrowing. In the event that any such Revolving Loan cannot for any reason be
made on the date otherwise required above, then each Lender hereby agrees that
it shall forthwith purchase (as of the date such borrowing would otherwise have
occurred, but adjusted for any payments received from the Borrower on or after
such date and prior to such purchase) from the Swingline Lender such
Participation Interests in such Swingline Loan as shall be necessary to cause
each Lender to share in such Swingline Loan ratably based upon its Revolving
Commitment Percentage (determined before giving effect to any termination of
the Commitments pursuant to Section 3.4); provided that (A) all interest
payable on such Swingline Loan shall be for the account of the Swingline Lender
until the date as of which the respective Participation Interest is

                                       28
<PAGE>
funded and (B) at the time the respective Participation Interest is funded,
the purchasing Lender shall pay to the Swingline Lender, to the extent not paid
to the Swingline Lender by the Borrower, interest on the principal amount of
such Participation Interest for each day from and including the day upon which
such borrowing would otherwise have occurred to but excluding the date of
funding of such Participation Interest, at a rate equal to the Federal Funds
Rate.

                                    SECTION 3
                 OTHER PROVISIONS RELATING TO CREDIT FACILITIES

         3.1      Default Rate.

         Upon the occurrence, and during the continuance, of an Event of
Default, the principal of and, to the extent permitted by law, interest on the
Loans and any other amounts owing hereunder or under the other Credit Documents
shall bear interest, payable on demand, at a per annum rate 2% greater than the
Adjusted Prime Rate.

         3.2      [Reserved].

         3.3      Prepayments.

         (a)  Voluntary Prepayments. The Loans may be prepaid in whole or
in part at any time without premium or penalty; provided partial prepayments
shall be in a minimum aggregate principal amount of $1,000,000 and integral
multiples of $100,000 in excess; provided further that in the event that an
"auto-borrow" or "zero balance" or other similar arrangement shall then be in
place with the Swingline Lender, then Swingline Loans shall be prepaid in such
minimum amounts, if any, provided by such agreement. Amounts repaid on the
Loans may be reborrowed in accordance with the provisions hereof.

         (b)  Mandatory Prepayments.

              (i)    Revolving Obligations. If at any time (A) the aggregate
         principal amount of Revolving Loans shall exceed the Aggregate
         Revolving Loan Committed Amount, (B) the aggregate principal amount of
         LOC Obligations shall exceed the LOC Committed Amount, (C) the
         aggregate principal amount of Swingline Loans shall exceed the
         Swingline Committed Amount or (D) the aggregate principal amount of
         Revolving Obligations shall exceed the Aggregate Committed Amount, the
         Borrower shall immediately make payments on the Revolving Obligations
         (including, if necessary, payments to a cash collateral account in
         respect of the LOC Obligations) in an amount equal to the excess.

              (ii)   Borrowing Base. If at any time the aggregate amount of
         Revolving Obligations shall exceed the sum of the Borrowing Base minus
         $1,000,000, the Borrower shall immediately make payment on the
         Revolving Obligations (including, if necessary, payments to a cash
         collateral account in respect of the LOC Obligations) in an amount
         equal to the excess.

              (iii)  Divestiture. The Revolving Obligations shall be
         immediately prepaid as hereafter provided in an amount equal to one
         hundred percent (100%) of the Net Cash Proceeds received by any Credit
         Party from any Divestiture.

         (c)  Application. Prepayments on Revolving Obligations pursuant to
Section 3.3(b)(ii) or Section 3.3(b)(iii) shall be applied first to the
Swingline Loans, then to the Revolving Loans and then to a cash

                                       29
<PAGE>
collateral account to secure the applicable LOC Obligations. Amounts repaid on
the Revolving Obligations may be reborrowed in accordance with the provisions
hereof.

         3.4      Termination and Reduction of Commitments

         (a)  Voluntary Reduction of Commitments. The Commitments may be
terminated or permanently reduced in whole or in part upon three (3) Business
Days' prior written notice by the Borrower to the Administrative Agent; provided
that (i) after giving effect to any voluntary reduction in the Commitments, the
aggregate principal amount of Revolving Obligations shall not exceed the
Aggregate Committed Amount, as reduced, and (ii) partial reductions shall be in
a minimum principal amount of $1,000,000 and in integral multiples of $100,000
in excess thereof.

         (b)  Mandatory Reduction of Commitments. Unless the Required Lenders
agree otherwise, the Aggregate Committed Amount shall be automatically and
permanently reduced by an amount equal to the amount of any prepayment required
by Section 3.3(b)(iii) in connection with any Divestiture to the extent that the
aggregate amount of Net Cash Proceeds received from all Divestitures from and
after the Closing Date exceeds $500,000.

         (c)  Termination of Commitments. Unless terminated earlier in
accordance with the terms of this Agreement, the Commitments hereunder shall
terminate on the Termination Date.

         3.5      Fees.

         (a)  Letters of Credit.

              (i)    Letter of Credit Fee. In consideration of the LOC
         Commitment, the Borrower agrees to pay to the Administrative Agent for
         the ratable benefit of the Lenders a fee (the "Letter of Credit Fee")
         equal to one and one-half percent (1.50%) per annum on the average
         daily maximum amount available to be drawn under Letters of Credit from
         the date of issuance to the date of expiration. The Letter of Credit
         Fee shall be payable quarterly in arrears on the 15th day following the
         last day of each calendar quarter for the immediately preceding
         calendar quarter (or portion thereof) beginning with the first such
         date to occur after the Closing Date (as well as on the Termination
         Date).

              (ii)   Issuing Lender Fees. In addition to the Letter of Credit
         Fee, the Borrower agrees to pay to the Issuing Lender for its own
         account without sharing by the other Lenders (A) a fronting and
         negotiation fee of one-eighth of one percent (0.125%) per annum on the
         average daily maximum amount available to be drawn under Letters of
         Credit from the date of issuance to the date of expiration (the
         "Issuing Lender Fees") and (B) the customary charges from time to time
         of the Issuing Lender with respect to the issuance, amendment,
         transfer, administration, cancellation and conversion of, and drawings
         under, the Letters of Credit. The Issuing Lender Fees shall be payable
         quarterly in arrears on the 15th day following the last day of each
         calendar quarter for the immediately preceding calendar quarter (or
         portion thereof) beginning with the first such date to occur after the
         Closing Date (as well as on the Termination Date). The customary
         charges shall be payable on demand.

         (b)  Commitment Fee. In consideration of the Revolving Commitments, the
Borrower agrees to pay to the Administrative Agent for the ratable benefit of
the Lenders a fee (the "Commitment Fee") equal to one-half of one percent (0.5%)
per annum on the average daily unused amount of the Aggregate

                                       30
<PAGE>
Committed Amount for the applicable period. The Commitment Fee shall be payable
quarterly in arrears on the 15th day following the last day of each calendar
quarter for the immediately preceding calendar quarter (or portion thereof)
beginning with the first such date to occur after the Closing Date (as well as
on the Termination Date). For purposes of computation of the Commitment Fee,
(A) Swingline Loans shall not be counted toward or considered usage of the
Aggregate Committed Amount and (B) LOC Obligations shall be counted toward and
considered usage of the Aggregate Committed Amount.

         (c)  Additional Fee. In the event a plan of reorganization acceptable
to the Lenders, the Bond Support Lenders and the Transit Lenders has not been
(i) confirmed by April 30, 2002 and/or (ii) consummated by May 15, 2002, the
Borrower shall pay to the Administrative Agent, for the ratable benefit of the
Lenders a fee (the "Additional Fee"), on the first Business Day after such
date, in the amount of $750,000. The fee provided under this Section 3.5(c) is
in lieu of and in substitution for the fee provided in Section 3.5(c) of the
Existing Credit Agreement.

         3.6      [Reserved].

         3.7      [Reserved].

         3.8      Capital Adequacy.

         If after the Closing Date, (a) the introduction of or any change in or
in the interpretation of any law or regulation, (b) compliance with any law or
regulation, or (c) compliance with any guideline or request from any central
bank or other Governmental Authority (whether or not having the force of law)
affects the amount of capital required or expected to be maintained by any
Lender or any corporation controlling any Lender and such Lender reasonably
determines that such amount is based upon the existence of such Lender's
Commitments, Extensions of Credit and its other commitments and loans of similar
type, then, within ten (10) Business Days of demand by such Lender (with a copy
of such demand to the Administrative Agent), the Borrower shall pay to the
Administrative Agent for the account of such Lender, from time to time as
specified by such Lender, additional amounts sufficient to compensate such
Lender in the light of such circumstances, to the extent that such Lender
reasonably determines such increase in capital to be allocable to the existence
of any or all of such Lender's Commitments and Extensions of Credit. A
certificate containing reasonably detailed calculations of such amounts
submitted to the Borrower and the Administrative Agent by such Lender shall be
conclusive and binding for all purposes absent manifest error.

         3.9      Increased Costs.

         If, after the Closing Date, due to either (a) the introduction of or
any change in or in the interpretation of any law or regulation or (b)
compliance with any guideline or request from any central bank or other
Governmental Authority (whether or not having the force of law), there shall be
any increase in the cost to any Lender of agreeing to make or making, funding or
maintaining any Loans, then the Borrower shall from time to time, within ten
(10) Business Days of demand by such Lender (with a copy of such demand to the
Administrative Agent), pay to the Administrative Agent for the account of such
Lender additional amounts sufficient to compensate such Lender for such
increased cost. A certificate containing reasonably detailed calculations of the
amount of such increased cost, submitted to the Borrower and the Administrative
Agent by such Lender, shall be conclusive and binding for all purposes, absent
manifest error.

         3.10     Taxes.

                                       31
<PAGE>
         (a)  Any and all payments by any Credit Party to or for the account of
any Lender or any Agent hereunder or under any other Credit Document shall be
made free and clear of and without deduction for any and all present or future
taxes, duties, levies, imposts, deductions, charges or withholdings, and all
liabilities with respect thereto, excluding, in the case of each Lender and each
Agent, taxes imposed on its income, and franchise taxes imposed on it, by the
jurisdiction under the laws of which such Lender (or its applicable lending
office) or such Agent (as the case may be) is organized or any political
subdivision thereof (all such non-excluded taxes, duties, levies, imposts,
deductions, charges, withholdings, and liabilities being hereinafter referred to
as "Taxes"). If any Credit Party shall be required by law to deduct any Taxes
from or in respect of any sum payable under this Agreement or any other Credit
Document to any Lender or either Agent, (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 3.10) such Lender or
such Agent receives an amount equal to the sum it would have received had no
such deductions been made, (ii) such Credit Party shall make such deductions,
(iii) such Credit Party shall pay the full amount deducted to the relevant
taxation authority or other authority in accordance with applicable law, and
(iv) such Credit Party shall furnish to such Agent, at its address referred to
in Section 12.1, the original or a certified copy of a receipt evidencing
payment thereof.

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

         (c)  The Borrower agrees to indemnify each Lender and each Agent for
the full amount of Taxes and Other Taxes (including, without limitation, any
Taxes or Other Taxes imposed or asserted by any jurisdiction on amounts payable
under this Section 3.10) paid by such Lender or such Agent (as the case may be)
and any liability (including penalties, interest, and expenses) arising
therefrom or with respect thereto.

         (d)  Each Lender that is not a United States person under Section
7701(a)(30) of the Internal Revenue Code, on or prior to the date of its
execution and delivery of this Agreement in the case of each Lender listed on
the signature pages hereof and on or prior to the date on which it becomes a
Lender in the case of each other Lender, and from time to time thereafter if
requested in writing by the Borrower or the Administrative Agent (but only so
long as such Lender remains lawfully able to do so), shall provide the Borrower
and the Administrative Agent with (i) Internal Revenue Service Form W-8 BEN or
W-8 ECI, as appropriate, or any successor form prescribed by the Internal
Revenue Service, certifying that such Lender is entitled to benefits under an
income tax treaty to which the United States is a party which reduces to zero
the rate of withholding tax on payments of interest or certifying that the
income receivable pursuant to this Agreement is effectively connected with the
conduct of a trade or business in the United States, (ii) Internal Revenue
Service Form W-8 or W-9, as appropriate, or any successor form prescribed by the
Internal Revenue Service, and/or (iii) any other form or certificate required by
any taxing authority (including any certificate required by Sections 871(h) and
881(c) of the Internal Revenue Code), certifying that such Lender is entitled to
an exemption from tax on payments pursuant to this Agreement or any of the other
Credit Documents.

         (e)  For any period with respect to which a Lender has failed to
provide the Borrower and the Administrative Agent with the appropriate form
pursuant to Section 3.10(d) (unless such failure is due to a change in treaty,
law, or regulation occurring subsequent to the date on which a form originally
was required to be provided), such Lender shall not be entitled to
indemnification under Section 3.10(a) or 3.10(b) with respect to Taxes imposed
by the United States; provided, however, that should a Lender, which is
otherwise exempt from withholding tax, become subject to Taxes because of its
failure to deliver

                                       32
<PAGE>
a form required hereunder, the Borrower shall take such steps as such Lender
shall reasonably request to assist such Lender to recover such Taxes.

         (f)  If any Credit Party is required to pay additional amounts to or
for the account of any Lender pursuant to this Section 3.10, then such Lender
will agree to use reasonable efforts to change the jurisdiction of its
applicable lending office so as to eliminate or reduce any such additional
payment which may thereafter accrue if such change, in the judgment of such
Lender, is not otherwise disadvantageous to such Lender.

         (g)  Without prejudice to the survival of any other agreement of the
Credit Parties hereunder, the agreements and obligations of the Credit Parties
contained in this Section 3.10 shall survive the repayment of the Loans, LOC
Obligations and other obligations under the Credit Documents and the termination
of the Commitments hereunder.

         3.11     [Reserved].

         3.12     [Reserved].

         3.13     Pro Rata Treatment.

         Except to the extent otherwise provided herein:

         (a)  Obligations. Each Revolving Loan, each payment or prepayment of
principal of any Revolving Loan, each payment of interest on any Revolving Loan,
each payment on or in respect of the LOC Obligations and each payment of
interest thereon, each payment of the Letter of Credit Fee, each payment of the
Commitment Fee and each reduction of Aggregate Committed Amount shall be
allocated pro rata among the Lenders according to their respective Revolving
Commitment Percentages.

         (b)  Advances.

              (i)    No Lender shall be responsible for the failure or delay by
         any other Lender in its obligation to make its ratable share of a
         borrowing hereunder; provided, however, that the failure of any Lender
         to fulfill its obligations hereunder shall not relieve any other Lender
         of its obligations hereunder.

              (ii)   Unless the Borrower or any Lender has notified the
         Administrative Agent prior to the date any payment is required to be
         made by it to the Administrative Agent hereunder, that the Borrower or
         such Lender, as the case may be, will not make such payment, the
         Administrative Agent may assume that the Borrower or such Lender, as
         the case may be, has timely made such payment and may (but shall not be
         so required to), in reliance thereon, make available a corresponding
         amount to the Person entitled thereto. If and to the extent that such
         payment was not in fact made to the Administrative Agent in immediately
         available funds, then:

                     (A)  if the Borrower failed to make such payment, each
              Lender shall forthwith on demand repay to the Administrative
              Agent the portion of such assumed payment that was made
              available to such Lender in immediately available funds,
              together with interest thereon in respect of each day from and
              including the date such amount was made available by the
              Administrative Agent to such Lender to the date such amount is
              repaid to the Administrative Agent in immediately available
              funds, at the Federal Funds Rate from time to time in effect;
              and

                                       33
<PAGE>
                     (B)  if any Lender failed to make such payment, such
              Lender shall forthwith on demand pay to the Administrative
              Agent the amount thereof in immediately available funds,
              together with interest thereon for the period from the date
              such amount was made available by the Administrative Agent to
              the Borrower to the date such amount is recovered by the
              Administrative Agent (the "Compensation Period") at a rate per
              annum equal to the Federal Funds Rate from time to time in
              effect. If such Lender does not pay such amount forthwith upon
              the Administrative Agent's demand therefor, the Administrative
              Agent may make a demand therefor upon the Borrower, and the
              Borrower shall pay such amount to the Administrative Agent,
              together with interest thereon for the Compensation Period at a
              rate per annum equal to the rate of interest applicable to the
              applicable borrowing.

         Nothing herein shall be deemed to relieve any Lender from its
         obligation to fulfill its Commitment or to prejudice any rights that
         the Administrative Agent or the Borrower may have against any Lender as
         a result of any default by such Lender hereunder. A notice of the
         Administrative Agent to any Lender with respect to any amount owing
         under this subsection (b) shall be conclusive, absent manifest error.

         3.14     Sharing of Payments.

         (a)  Lenders. The Lenders agree among themselves that, in the event
that any Lender shall obtain payment in respect of any Loan, LOC Obligation or
any other obligation owing to such Lender under this Agreement through the
exercise of a right of setoff, banker's lien or counterclaim, or pursuant to a
secured claim under Section 364 of the Bankruptcy Code or other security or
interest arising from, or in lieu of, such secured claim, received by such
Lender under any applicable bankruptcy, insolvency or other similar law or
otherwise, or by any other means, in excess of its pro rata share of such
payment as provided for in this Agreement, such Lender shall promptly purchase
from the other Lenders a participation in such Loan, LOC Obligation and other
obligations in such amounts, and make such other adjustments from time to time,
as shall be equitable to the end that all Lenders share such payment in
accordance with their respective ratable shares as provided for in this
Agreement. The Lenders further agree among themselves that if payment to any
such Lender obtained by such Lender through the exercise of a right of setoff,
banker's lien, counterclaim or other event as aforesaid shall be rescinded or
must otherwise be restored, each Lender which shall have shared the benefit of
such payment shall, by repurchase of a participation theretofore sold, return
its share of that benefit (together with its share of any accrued interest
payable with respect thereto) to each Lender whose payment shall have been
rescinded or otherwise restored. The Borrower agrees that any Lender so
purchasing such a participation may, to the fullest extent permitted by law,
exercise all rights of payment, including setoff, banker's lien or
counterclaim, with respect to such participation as fully as if such Lender
were a holder of such Loan, LOC Obligation or other obligation in the amount of
such participation. If under any applicable bankruptcy, insolvency or other
similar law, any Lender receives a secured claim in lieu of a setoff to which
this Section 3.14 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent
with the rights of the Lenders under this Section 3.14 to share in the benefits
of any recovery on such secured claim.

         (b)  Lenders and Agents. Except as otherwise expressly provided in this
Agreement, if any Lender or any Agent shall fail to remit to any other Agent or
any other Lender an amount payable by such Lender or such Agent to such other
Agent or such other Lender pursuant to this Agreement on the date when such
amount is due, such payments shall be made together with interest thereon for
each date from the date such amount is

                                       34
<PAGE>
due until the date such amount is paid to such other Agent or such other Lender
at a rate per annum equal to the Federal Funds Rate.

         3.15     Payments, Computations, Etc.

         (a)  Payments by the Borrower. Except as otherwise specifically
provided herein, all payments of principal, interest and fees hereunder shall
be made to the Administrative Agent in Dollars in immediately available funds,
without condition or deduction for any counterclaim, defense, recoupment or
setoff, at the Administrative Agent's office specified in Section 12.1 not
later than 2:00 P.M. (Charlotte, North Carolina time) on the date when due.
Payments received after such time shall be deemed to have been received on the
next succeeding Business Day. The Administrative Agent may (but shall not be
obligated to) debit the amount of any such payment which is not made by such
time to any ordinary deposit account of the Borrower maintained with the
Administrative Agent (with notice to the Borrower). The Borrower shall, at the
time it makes any payment under this Agreement, specify to the Administrative
Agent the Loans, LOC Obligations, Fees, interest or other amounts payable by
the Borrower hereunder to which such payment is to be applied (and in the event
that it fails so to specify, or if such application would be inconsistent with
the terms hereof, the Administrative Agent shall distribute such payment to the
Lenders in such manner as the Administrative Agent may determine to be
appropriate in respect of obligations owing by the Borrower hereunder, subject
to the terms of Section 3.13(a)). The Administrative Agent will distribute such
payments to the Lenders if any such payment is received prior to 12:00 Noon
(Charlotte, North Carolina time) on a Business Day in like funds as received
prior to the end of such Business Day and otherwise the Administrative Agent
will distribute such payment to such Lenders entitled thereto on the next
succeeding Business Day. Whenever any payment hereunder shall be stated to be
due on a day which is not a Business Day, the due date thereof shall be
extended to the next succeeding Business Day (subject to accrual of interest
and Fees for the period of such extension). Except as expressly provided
otherwise herein, all computations of fees shall be made on the basis of the
actual number of days elapsed over a year of 360 days and all computations of
interest shall be made on the basis of the actual number of days elapsed over a
year of 365 or 366 days, as appropriate. Interest shall accrue from and include
the date of borrowing, but exclude the date of payment.

         (b)  Advances by Lenders. Upon notice by the Administrative Agent of
its receipt of a Notice of Borrowing in accordance with Section 2.2(a)(i), each
Lender will make its Revolving Commitment Percentage of each Revolving Loan
borrowing available to the Administrative Agent for the account of the
Borrower, or in such other manner as the Administrative Agent may specify in
writing, by 1:00 P.M. (Charlotte, North Carolina time) on the date specified in
the applicable Notice of Borrowing in Dollars and in funds immediately
available to the Administrative Agent.

         (c)  Allocation of Payments After Event of Default. Notwithstanding any
other provisions of this Agreement to the contrary, after the occurrence and
during the continuance of an Event of Default, all amounts collected or received
by the Administrative Agent or any Lender on account of the Revolving
Obligations or any other amounts outstanding under any of the Credit Documents
shall be paid over or delivered as follows:

              FIRST, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation reasonable attorneys' fees)
         of the Agents in connection with enforcing the rights of the Lenders
         under the Credit Documents;

              SECOND, to the payment of all reasonable out-of-pocket costs
         and expenses (including without limitation, reasonable attorneys' fees)
         of each of the Lenders in connection with enforcing its rights under
         the Credit Documents or otherwise with respect to the Revolving
         Obligations owing to such Lender;

                                       35
<PAGE>
              THIRD, to the payment of all accrued interest and Fees on or in
         respect of the Revolving Obligations;

              FOURTH, to the payment of the outstanding principal amount of
         the Revolving Obligations (including the payment of all LOC Obligations
         then reimbursable by the Borrower pursuant to Section 2.6(d), but
         excluding any LOC Obligations attributable to issued but undrawn
         Letters of Credit);

              FIFTH, to the cash collateralization of all LOC Obligations
         attributable to issued but undrawn Letters of Credit;

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

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

In carrying out the foregoing, (i) amounts received shall be applied in the
numerical order provided until exhausted prior to application to the next
succeeding category; and (ii) each of the Lenders shall receive an amount equal
to its pro rata share (based on the proportion that then outstanding Obligations
held by such Lender bears to the aggregate then outstanding Obligations (to the
extent permitted hereunder)) of amounts available to be applied pursuant to
clauses "SECOND", "THIRD", "FOURTH" and "FIFTH" above; and (iii) all amounts
available to be applied to pursuant to clause "FIFTH" above shall be held by the
Administrative Agent in a cash collateral account and applied (A) first, to
reimburse the Issuing Lender for any drawings under such Letters of Credit and
(B) then, following the expiration of all Letters of Credit, to all other
obligations of the types described in clauses "FIFTH" and "SIXTH" above in the
manner provided in this Section 3.15(c).

         3.16     Evidence of Debt.

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

         (b)  The Administrative Agent shall maintain the Register pursuant to
Section 12.3(c), and a subaccount for each Lender, in which Register and
subaccounts (taken together) shall be recorded (i) the amount and type of each
Loan, (ii) the amount of any principal or interest due and payable or to become
due and payable to each Lender hereunder and (iii) the amount of any sum
received by the Administrative Agent hereunder from or for the account of the
Borrower and each Lender's share thereof. The Administrative Agent will make
reasonable efforts to maintain the accuracy of the subaccounts referred to in
the preceding sentence and to promptly update such subaccounts from time to
time, as necessary.

         (c)  The entries made in the Register, accounts and subaccounts
maintained pursuant to subsection (b) of this Section 3.16 (and, if consistent
with the entries of the Administrative Agent, subsection (a)) shall be prima
facie evidence of the existence and amounts of the obligations of the Borrower
therein recorded; provided, however, that the failure of any Lender or the
Administrative Agent to maintain the Register, any such account,

                                       36
<PAGE>
or such subaccount, as applicable, or any error therein, shall not in any
manner affect the obligation of the Borrower to repay the Loans and other
obligations owing to such Lenders in accordance with the terms hereof.

                                    SECTION 4
                                    GUARANTY

         4.1      The Guarantee.

         (a)  Each of the Guarantors hereby jointly and severally guarantees to
each Lender and to the Agents, as hereinafter provided, the prompt payment of
the Guaranteed Obligations in full when due (whether at stated maturity, as a
mandatory prepayment, by acceleration, as a mandatory cash collateralization or
otherwise) strictly in accordance with the terms thereof. The Guarantors hereby
further agree that if any of the Guaranteed Obligations are not paid in full
when due (whether at stated maturity, as a mandatory prepayment, by
acceleration, as a mandatory cash collateralization or otherwise), the
Guarantors will, jointly and severally, promptly pay the same, without any
demand or notice whatsoever, and that in the case of any extension of time of
payment or renewal of any of the Guaranteed Obligations, the same will be
promptly paid in full when due (whether at extended maturity, as a mandatory
prepayment, by acceleration, as a mandatory cash collateralization or otherwise)
in accordance with the terms of such extension or renewal.

         (b)  Notwithstanding any provision to the contrary contained herein or
in any other of the Credit Documents, to the extent the obligations of a
Guarantor shall be adjudicated to be invalid or unenforceable for any reason
(including, without limitation, because of any applicable state, provincial or
federal law relating to fraudulent conveyances or transfers or the granting of
financial assistance) then the obligations of each Guarantor hereunder shall be
limited to the maximum amount that is permissible under applicable law (whether
federal, state or provincial and including, without limitation, the Bankruptcy
Code). In such case or otherwise at the request of an Agent, each Credit Party
shall take such action and shall execute and deliver all such further documents
required by such Agent to cause the obligations of such Guarantor to be
enforceable to the extent required by this Agreement.

         4.2      Obligations Unconditional.

         The obligations of the Guarantors under Section 4.1 are joint and
several, absolute and unconditional, irrespective of the value, genuineness,
validity, regularity or enforceability of any of the Credit Documents or any
other agreement or instrument referred to therein, or any substitution, release
or exchange of any other guarantee of or security for any of the Guaranteed
Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever which might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section 4.2 that the obligations of each of the
Guarantors hereunder shall be absolute and unconditional under any and all
circumstances. Each Guarantor agrees that such Guarantor shall have no right of
subrogation, indemnity, reimbursement or contribution against the Borrower or
any other Guarantor for amounts paid under this Section 4 until such time as all
of the Lenders have been paid in full, all Commitments under this Agreement have
been terminated and no Person or Governmental Authority shall have any right to
request any return or reimbursement of funds from the Lenders in connection with
monies received under the Credit Documents. Without limiting the generality of
the foregoing, it is agreed that, to the fullest extent permitted by law, the
occurrence of any one or more of the following shall not alter or impair the
liability of any Guarantor hereunder which shall remain absolute and
unconditional as described above:

                                       37
<PAGE>
              (i)    at any time or from time to time, without notice to any
         Guarantor, the time for any performance of or compliance with any of
         the Guaranteed Obligations shall be extended, or such performance or
         compliance shall be waived;

              (ii)   any of the acts mentioned in any of the provisions of any
         of the Credit Documents or any other agreement or instrument referred
         to in the Credit Documents shall be done or omitted;

              (iii)  the maturity of any of the Guaranteed Obligations shall
         be accelerated, or any of the Guaranteed Obligations shall be modified,
         supplemented or amended in any respect, or any right under any of the
         Credit Documents or any other agreement or instrument referred to in
         the Credit Documents shall be waived or any other guarantee of any of
         the Guaranteed Obligations or any security therefor shall be released
         or exchanged in whole or in part or otherwise dealt with;

              (iv)   any Lien granted to, or in favor of, any Agent or any
         Lender or Lenders as security for any of the Guaranteed Obligations
         shall fail to attach or be perfected; or

              (v)    any of the Guaranteed Obligations shall be determined to
         be void or voidable (including, without limitation, for the benefit of
         any creditor of any Guarantor) or shall be subordinated to the claims
         of any Person (including, without limitation, any creditor of any
         Guarantor).

With respect to its obligations hereunder, each Guarantor hereby expressly
waives diligence, presentment, demand of payment, protest and all notices
whatsoever, and any requirement that the Administrative Agent or any Lender
exhaust any right, power or remedy or proceed against any Person under any of
the Credit Documents or any other agreement or instrument referred to in the
Credit Documents or against any other Person under any other guarantee of, or
security for, any of the Guaranteed Obligations.

         4.3      Reinstatement.

         The obligations of the Guarantors under this Section 4 shall be
automatically reinstated if and to the extent that for any reason any payment by
or on behalf of any Person in respect of the Guaranteed Obligations is rescinded
or must be otherwise restored by any holder of any of the Guaranteed
Obligations, whether as a result of any proceedings in bankruptcy or
reorganization or otherwise, and each Guarantor agrees that it will indemnify
the Agents and each Lender on demand for all reasonable costs and expenses
(including, without limitation, reasonable fees and expenses of counsel)
incurred by the Agents or such Lender in connection with such rescission or
restoration, including any such costs and expenses incurred in defending against
any claim alleging that such payment constituted a preference, fraudulent
transfer or similar payment under any bankruptcy, insolvency or similar law.

         4.4      Certain Additional Waivers.

         Each Guarantor agrees that such Guarantor shall have no right of
recourse to security for the Guaranteed Obligations, except through the exercise
of the rights of subrogation pursuant to Section 4.2.

         4.5      Remedies.

         The Guarantors agree that, to the fullest extent permitted by law, as
between the Guarantors, on the one hand, and the Agents and the Lenders, on the
other hand, the Guaranteed Obligations may be declared to be forthwith due and
payable as provided in Section 10.2 (and shall be deemed to have become
automatically due and payable in the circumstances provided in said Section
10.2) for purposes of Section 4.1 notwithstanding any

                                       38
<PAGE>
stay, injunction or other prohibition preventing such declaration (or
preventing the Guaranteed Obligations from becoming automatically due and
payable) as against any other Person and that, in the event of such declaration
(or the Guaranteed Obligations being deemed to have become automatically due
and payable), the Guaranteed Obligations (whether or not due and payable by any
other Person) shall forthwith become due and payable by the Guarantors for
purposes of Section 4.1.

         4.6      Rights of Contribution.

         The Guarantors hereby agree, as among themselves, that if any Guarantor
shall become an Excess Funding Guarantor (as defined below), each other
Guarantor shall, on demand of such Excess Funding Guarantor (but subject to the
succeeding provisions of this Section 4.6), pay to such Excess Funding Guarantor
an amount equal to such Guarantor's Pro Rata Share (as defined below and
determined, for this purpose, without reference to the Facilities, assets,
liabilities and debts of such Excess Funding Guarantor) of such Excess Payment
(as defined below). The payment obligation of any Guarantor to any Excess
Funding Guarantor under this Section 4.6 shall be subordinate and subject in
right of payment to the prior payment in full of the obligations of such
Guarantor under the other provisions of this Section 4, and such Excess Funding
Guarantor shall not exercise any right or remedy with respect to such excess
until payment and satisfaction in full of all of such obligations. For purposes
hereof, (a) "Excess Funding Guarantor" shall mean, in respect of any obligations
arising under the other provisions of this Section 4 (hereafter, the "Guarantied
Obligations"), a Guarantor that has paid an amount in excess of its Pro Rata
Share of the Guarantied Obligations; (b) "Excess Payment" shall mean, in respect
of any Guarantied Obligations, the amount paid by an Excess Funding Guarantor in
excess of its Pro Rata Share of such Guarantied Obligations; and (c) "Pro Rata
Share", for the purposes of this Section 4.6, shall mean, for any Guarantor, the
ratio (expressed as a percentage) of (i) the amount by which the aggregate
present fair saleable value of all of its assets and Facilities exceeds the
amount of all debts and liabilities of such Guarantor (including contingent,
subordinated, unmatured, and unliquidated liabilities, but excluding the
obligations of such Guarantor hereunder) to (ii) the amount by which the
aggregate present fair saleable value of all assets and other Facilities of the
Borrower and all of the Guarantors exceeds the amount of all of the debts and
liabilities (including contingent, subordinated, unmatured, and unliquidated
liabilities, but excluding the obligations of the Borrower and the Guarantors
hereunder) of the Borrower and all of the Guarantors, all as of the Closing Date
(if any Guarantor becomes a party hereto subsequent to the Closing Date, then
for the purposes of this Section 4.6 such subsequent Guarantor shall be deemed
to have been a Guarantor as of the Closing Date and the information pertaining
to, and only pertaining to, such Guarantor as of the date such Guarantor became
a Guarantor shall be deemed true as of the Closing Date).

         4.7      Continuing Guarantee.

         The guarantee in this Section 4 is a continuing guarantee, and shall
apply to all Guaranteed Obligations whenever arising.

                                    SECTION 5

         Each Credit Party owns, or has the legal right to use, the Intellectual
Property necessary for each of them to conduct its business as currently
conducted, except to the extent the failure to do so would not be reasonably
expected to have a Material Adverse Effect. No claim has been asserted and is
pending by any Person challenging or questioning the use of any such
Intellectual Property or the validity or effectiveness of any such Intellectual
Property, nor does any Credit Party know of any such claim, and the use of such
Intellectual Property by the Credit Parties does not infringe on the rights of

returns and material reports required to be filed, and has paid all
post-petition federal and other taxes, assessments, fees and other governmental
charges levied or imposed upon it or its Facilities, income or assets otherwise
due and payable unless such unpaid taxes and assessments are (a) not yet past
due or (b) being contested in good faith and by appropriate proceedings
diligently pursued and as to which adequate reserves determined in accordance
with GAAP have been established on such Credit Party's books and records and no
Lien with respect to nonpayment thereof has been asserted. No Credit Party is
aware of any proposed tax assessments against it, with respect to any prior
period, in excess of amounts accrued on its financial statements (as required to
be accrued in accordance with GAAP), nor does any Credit Party anticipate any
further material tax liability with respect to any open taxable years taken as a
whole in excess of accrued amounts.

         6.12     ERISA

         Except as would not reasonably be expected to have a Material Adverse

representation is made or deemed made: (i) no ERISA Event has occurred, and, to
the best knowledge of the Credit Parties, no event or condition has occurred or
exists as a result of which any ERISA Event could reasonably be expected to
occur, with respect to any Plan; (ii) no "accumulated funding deficiency," as
such term is defined in Section 302 of ERISA and Section 412 of the Internal
Revenue Code, whether or not waived, has occurred with respect to any Plan;
(iii) each Plan has been maintained, operated, and funded in compliance with its
own terms and in material compliance with the provisions of ERISA, the Internal
Revenue Code, and any other applicable federal or state

                                       44
<PAGE>
laws; and (iv) no lien in favor of the PBGC or a Plan has arisen or is
reasonably likely to arise on account of any Plan.

         (b)  The actuarial present value of all "benefit liabilities" (as
defined in Section 4001(a)(16) of ERISA), whether or not vested, under each
Single Employer Plan, as of the last annual valuation date prior to the date on
which this representation is made or deemed made (determined, in each case, in
accordance with Financial Accounting Standards Board Statement 87, utilizing the
actuarial assumptions used in such Plan's most recent actuarial valuation
report), did not exceed as of such valuation date the fair market value of the
assets of such Plan.

         (c)  Neither any Credit Party nor any ERISA Affiliate has incurred, or,
to the best knowledge of the Credit Parties, could be reasonably expected to
incur, any withdrawal liability under ERISA to any Multiemployer Plan or
Multiple Employer Plan. Neither any Credit Party nor any ERISA Affiliate would
become subject to any withdrawal liability under ERISA if any Credit Party or
any ERISA Affiliate were to withdraw completely from all Multiemployer Plans and
Multiple Employer Plans as of the valuation date most closely preceding the date
on which this representation is made or deemed made. Neither any Credit Party
nor any ERISA Affiliate has received any notification that any Multiemployer

insolvent (within the meaning of Section 4245 of ERISA), or has been terminated
(within the meaning of Title IV of ERISA), and no Multiemployer Plan is, to the
best knowledge of the Credit Parties, reasonably expected to be in
reorganization, insolvent, or terminated.

ERISA or Section 4975 of the Internal Revenue Code) or breach of fiduciary
responsibility has occurred with respect to a Plan which has subjected or may
subject any Credit Party or any ERISA Affiliate to any liability under Sections
406, 409, 502(i), or 502(l) of ERISA or Section 4975 of the Internal Revenue
Code, or under any agreement or other instrument pursuant to which any Credit
Party or any ERISA Affiliate has agreed or is required to indemnify any person
against any such liability.

         (e)  Neither any Credit Party nor any ERISA Affiliates has any material
liability with respect to "expected post-retirement benefit obligations" within
the meaning of the Financial Accounting Standards Board Statement 106. Each Plan
which is a welfare plan (as defined in Section 3(1) of ERISA) to which Sections
601-609 of ERISA and Section 4980B of the Internal Revenue Code apply has been
administered in compliance in all material respects of such sections.

         (f)  Neither the execution and delivery of this Agreement nor the
consummation of the financing transactions contemplated thereunder will involve
any transaction which is subject to the prohibitions of Sections 404, 406 or 407
of ERISA or in connection with which a tax could be imposed pursuant to Section
4975 of the Internal Revenue Code. The representation by the Credit Parties in
the preceding sentence is made in reliance upon and subject to the accuracy of
the Lenders' representation in Section 12.15 with respect to their source of
funds and is subject, in the event that the source of the funds used by the
Lenders in connection with this transaction is an insurance company's general
asset account, to the application of Prohibited Transaction Class Exemption
95-60, 60 Fed. Reg. 35,925 (1995), compliance with the regulations issued under
Section 401(c)(1)(A) of ERISA, or the issuance of any other prohibited
transaction exemption or similar relief, to the effect that assets in an
insurance company's general asset account do not constitute assets of an
"employee benefit plan" within the meaning of Section 3(3) of ERISA or a "plan"
within the meaning of Section 4975(e)(1) of the Internal Revenue Code.

remedies as a result of an Event of Default, the Credit Parties shall be
permitted to pay compensation and reimbursement of expenses accrued and payable
under 11 U.S.C. [sec] 330 and 11 U.S.C. [sec] 331, as the same may be due and

referred to above and shall not affect the right of the Credit Parties, the
Agents or the Lenders to object to the allowance and payment of such amounts.
Notwithstanding any other provision of this Agreement to the contrary, the

Supplemental DIP Financing Order and the Final DIP Financing Order, the Liens
in favor of the Collateral Agent on behalf of the Lenders in all of such real
property and leasehold interests, and all of the other Collateral, shall be
perfected without the taking of any further action, including any recordation
of any instruments of mortgage or assignment, or the recording or filing of any
financing statements, notices of lien or other similar instruments.

         (q)  Order of Bankruptcy Court. An order shall be entered by the
Bankruptcy Court confirming a plan of reorganization or liquidation in the
Bankruptcy Cases which does not contain a provision for termination of all of

before the effective date of such plan.

         10.2     Acceleration; Remedies.

         Upon the occurrence and during the continuation of an Event of Default,
without further order of, application to, or action by the Bankruptcy Court, the
Administrative Agent (a) may, and shall upon the request of the Required
Lenders, by written notice to the Borrower declare that all or any portion of
the Commitments be terminated, whereupon the obligation of each Lender to make
any Extension of Credit shall immediately terminate, and/or (b) may, and shall
upon the request of the Required Lenders, by written notice to the Borrower
declare the Revolving Obligations, all interest thereon and all other amounts
and obligations payable under this Agreement to be forthwith due and payable,
whereupon the Revolving Obligations, all such interest, and all such amounts and
the obligations shall become and be forthwith due and payable, without
presentment, demand, protest or other notice of any kind, all of which are
hereby waived by the Borrower. In addition, subject solely to any requirement of
the giving of notice by the terms of the Final DIP Financing Order, the
automatic stay provided in Section 362 of the Bankruptcy Code shall be
automatically vacated without further action or order of the Bankruptcy Court,
and the Agents and the Lenders shall be entitled to exercise all of their
respective rights and remedies under the Credit Documents and applicable law,
including without limitation, all rights and remedies with respect to the
Collateral and the Guarantors.

                                   SECTION 11
                                     AGENTS

         11.1     Appointment and Authorization of Agents.

         (a)  Each Lender hereby irrevocably (subject to Section 11.9) appoints,
designates and authorizes each Agent to take such action on its behalf under the
provisions of this Agreement and each other Credit Document and to exercise such
powers and perform such duties as are expressly delegated to such Agent by the
terms of this Agreement or any other Credit Document, together with such powers
as are reasonably incidental thereto. Notwithstanding any provision to the
contrary contained elsewhere herein or in any other Credit Document, the Agents
shall not have any duties or responsibilities, except those expressly set forth
herein, nor shall the Agents have or be deemed to have any fiduciary
relationship with any Lender or participant, and no implied covenants,
functions, responsibilities, duties, obligations or liabilities shall be read
into this Agreement or any other Credit Document or otherwise exist against the
Agents. Without limiting the generality of the foregoing sentence, the use of
the term "agent" herein and in the other Credit Documents with reference to the
Agents is not intended to connote any fiduciary or other implied (or express)
obligations arising under agency doctrine of any applicable law. Instead, such
term is used merely as a matter of market custom, and is intended to create or
reflect only an administrative relationship between independent contracting
parties.

         (b)  The Issuing Lender shall act on behalf of the Lenders with respect
to any Letters of Credit issued by the Issuing Lender and the documents
associated therewith until such time (and except for so long) as the
Administrative Agent may agree at the request of the Required Lenders to act for
the Issuing Lender with respect thereto; provided, however, that the Issuing
Lender shall have all of the benefits and immunities (i) provided to the Agents
in this Section 11 with respect to any acts taken or omissions suffered by the
Issuing Lender in connection with Letters of Credit issued by it or proposed to
be issued by it and the application and agreements for letters of credit
pertaining to such Letters of Credit as fully as if the term "Agent" as used in
this Section 11 included the Issuing Lender with respect to such acts or
omissions, and (ii) as additionally provided herein with respect to the Issuing
Banks.

         11.2     Delegation of Duties.

         Each Agent may execute any of its duties under this Agreement or any
other Credit Document by or through agents, employees or attorneys-in-fact and
shall be entitled to advice of counsel and other consultants or experts
concerning all matters pertaining to such duties. Neither Agent shall be
responsible for the negligence or misconduct of any agent or attorney-in-fact
that it selects in the absence of gross negligence or willful misconduct.

         11.3     Liability of Agents.

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

         11.4     Reliance by Agents.

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

         (b)  For purposes of determining compliance with the conditions
specified in Section 5.1, each Lender that has signed this Agreement shall be
deemed to have consented to, approved or accepted or to be satisfied with, each
document or other matter either sent by any Agent to such Lender for consent,
approval, acceptance or satisfaction, or required thereunder to be consented to
or approved by or acceptable or satisfactory to a Lender.

         11.5     Notice of Default.

         Neither Agent shall be deemed to have knowledge or notice of the
occurrence of any Default or Event of Default, except for the Administrative
Agent with respect to defaults in the payment of principal, interest and fees
required to be paid to the Administrative Agent for the account of the Lenders,
unless such Agent shall have received written notice from a Lender or the
Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default." The applicable
Agent will notify the Lenders of its receipt of any such notice. The Agents
shall take such action with respect to such Default or Event of Default as may
be directed by the Required Lenders in accordance with Section 10; provided,
however, that unless and until the Agents have received any such direction, the
Agents may (but shall not be obligated to) take such action, or refrain from
taking such action, with respect to such Default or Event of Default as it shall
deem advisable or in the best interest of the Lenders.

         11.6     Credit Decision; Disclosure of Information by Agent.

         Each Lender acknowledges that no Agent-Related Person has made any
representation or warranty to it, and that no act by an Agent hereinafter taken,
including any consent to and acceptance of any assignment or review of the
affairs of any Credit Party or any Affiliate thereof, shall be deemed to
constitute any representation or warranty by any Agent-Related Person to any
Lender as to any matter, including whether Agent-Related Persons have disclosed
material information in their possession. Each Lender represents to the Agents
that it has, independently and without reliance upon any Agent-Related Person
and based on such documents and information as it has deemed appropriate, made
its own appraisal of and investigation into the business, prospects, operations,
property, financial and other condition and creditworthiness of the Credit
Parties and their respective Subsidiaries, and all applicable banking or other
regulatory laws relating to the transactions contemplated hereby, and made its
own decision to enter into this Agreement and to extend credit to the Borrower
and the other Credit Parties hereunder. Each Lender also represents that it
will, independently and without reliance upon any Agent-Related Person and based
on such documents and information as it shall deem appropriate at the time,
continue to make its own credit analysis, appraisals and decisions in taking or
not taking action under this Agreement and the other Credit Documents, and to
make such investigations as it deems necessary to inform itself as to the
business, prospects, operations, property, financial and other condition and
creditworthiness of the Borrower and the other Credit Parties. Except for
notices, reports and other documents expressly required to be furnished to the
Lenders by the Agents herein, the Agents shall not have any duty or
responsibility to provide any Lender with any credit or other information
concerning the business, prospects, operations, property, financial and other
condition or creditworthiness of any of the Credit Parties or any of their
respective Affiliates which may come into the possession of any Agent-Related
Person.

         11.7     Indemnification of Agent.

         Whether or not the transactions contemplated hereby are consummated,
the Lenders shall indemnify upon demand each Agent-Related Person (to the extent
not reimbursed by or on behalf of any Credit Party and without limiting the
obligation of any Credit Party to do so), pro rata, and hold harmless each
Agent-Related Person from and against any and all Indemnified Liabilities
incurred by it; provided, however, that no Lender shall be liable for the
payment to any Agent-Related Person of any portion of such Indemnified
Liabilities resulting from such Person's gross negligence or willful misconduct;
provided, however, that no action taken in accordance with the directions of the
Required Lenders shall be

                                       69
<PAGE>
deemed to constitute gross negligence or willful misconduct for purposes of
this Section. Without limitation of the foregoing, each Lender shall reimburse
the Agents upon demand for its ratable share of any costs or out-of-pocket
expenses (including reasonable fees and costs of counsel) incurred by the
Agents in connection with the preparation, execution, delivery, administration,
modification, amendment or enforcement (whether through negotiations, legal
proceedings or otherwise) of, or legal advice in respect of rights or
responsibilities under, this Agreement, any other Credit Document, or any
document contemplated by or referred to herein, to the extent that the Agent is
not reimbursed for such expenses by or on behalf of the Borrower. The
undertaking in this Section shall survive termination of the Commitments, the
payment of all Obligations hereunder and the resignation or replacement of any
Agent.

         11.8     Agents in their Individual Capacity.

         Bank of America and its Affiliates may make loans to, issue letters of
credit for the account of, accept deposits from, acquire equity interests in and
generally engage in any kind of banking, trust, financial advisory, underwriting
or other business with each of the Credit Parties and their respective
Affiliates as though Bank of America were not an Agent or the Issuing Lender
hereunder and without notice to or consent of the Lenders. The Lenders
acknowledge that, pursuant to such activities, Bank of America or its Affiliates
may receive information regarding any Credit Party or its Affiliates (including
information that may be subject to confidentiality obligations in favor of such
Credit Party or such Affiliate) and acknowledge that the Agents shall be under
no obligation to provide such information to them. With respect to its Loans,
Bank of America shall have the same rights and powers under this Agreement as
any other Lender and may exercise such rights and powers as though it were not
the Agent or the Issuing Bank, and the terms "Lender" and "Lenders" include Bank
of America in its individual capacity.

         11.9     Successor Agents.

         The Administrative Agent may resign as Administrative Agent and/or the
Collateral Agent may resign as Collateral Agent in each case upon 30 days'
notice to the Lenders and the Borrower. If an Agent resigns under this
Agreement, the Required Lenders shall appoint from among the Lenders a successor
for such Agent for the Lenders which successor Agent shall be consented to by
the Borrower at all times other than during the existence of an Event of Default
(which consent of the Borrower shall not be unreasonably withheld or delayed).
If no successor Agent is appointed prior to the effective date of the
resignation of such Agent, such resigning Agent may appoint, after consulting
with the Lenders and the Borrower, a successor for such Agent from among the
Banks. Upon the acceptance of its appointment as successor Agent hereunder, such
successor Agent shall succeed to all the rights, powers and duties of the
resigning Agent and the term "Agent" shall mean such successor Agent and the
resigning Agent's appointment, powers and duties as Agent shall be terminated.
After any resigning Agent's resignation hereunder as such Agent, the provisions
of this Section 11 and Sections 12.4 and 12.9 shall inure to its benefit as to
any actions taken or omitted to be taken by it while it was Agent under this
Agreement. If no successor for such Agent has accepted appointment as such Agent
by the date which is 30 days following a resigning Agent's notice of
resignation, the resigning Agent's resignation shall nevertheless thereupon
become effective and the Lenders shall perform all of the duties of the
resigning Agent hereunder until such time, if any, as the Required Lenders
appoint a successor agent as provided for above.

         11.10    Other Agents; Lead Managers.

         None of the Lenders identified on the facing page or signature pages of
this Agreement as a "syndication agent," "documentation agent," "co-agent" or
"lead manager" shall have any right, power,

                                       70
<PAGE>
obligation, liability, responsibility or duty under this Agreement other than
those applicable to all Lenders as such. Without limiting the foregoing, none
of the Lenders so identified shall have or be deemed to have any fiduciary
relationship with any Lender. Each Lender acknowledges that it has not relied,
and will not rely, on any of the Lenders so identified in deciding to enter
into this Agreement or in taking or not taking action hereunder.

         12.2     Right of Set-Off.

         In addition to any rights now or hereafter granted under applicable law
or otherwise, and not by way of limitation of any such rights, upon the
occurrence of an Event of Default, each Lender is authorized at any time and
from time to time, without presentment, demand, protest or other notice of any
kind (all of which rights being hereby expressly waived), to set-off and to
appropriate and apply any and all deposits (general or special) and any other
indebtedness at any time held or owing by such Lender (including, without
limitation branches, agencies or Affiliates of such Lender wherever located) to
or for the credit or the account of any Credit Party against obligations and
liabilities of such Person to such Lender hereunder, under the Notes, the other
Credit Documents or otherwise, irrespective of whether such Lender shall have
made any demand hereunder and although such obligations, liabilities or claims,
or any of them, may be contingent or unmatured, and any such set-off shall be
deemed to have been made immediately upon the occurrence of an Event of Default
even though such charge is made or entered on the books of such Lender
subsequent thereto. Any Person purchasing a participation in the Loans and
Commitments hereunder pursuant to Section 3.14 or Section 12.3(d) may exercise
all rights of set-off with respect to its participation interest as fully as if
such Person were a Lender hereunder. NOTWITHSTANDING THE FOREGOING, NO LENDER
(NOR ANY PARTICIPANT OF A LENDER) SHALL EXERCISE ANY RIGHT OF SET-OFF, BANKER'S
LIEN, OR THE LIKE AGAINST ANY DEPOSIT ACCOUNT OR PROPERTY OF ANY CREDIT PARTY
HELD OR MAINTAINED BY SUCH LENDER WITHOUT THE PRIOR WRITTEN CONSENT OF THE
REQUIRED LENDERS.

         12.3     Successors and Assigns.

         (a)  The provisions of this Agreement shall be binding upon and inure
to the benefit of the parties hereto and their respective successors and assigns
permitted hereby, except that the Borrower may not assign or otherwise transfer
any of its rights or obligations hereunder without the prior written consent of
each Lender (and any attempted assignment or transfer by the Borrower without
such consent shall be null and void). Nothing in this Agreement, expressed or
implied, shall be construed to confer upon any Person (other than the parties
hereto, their respective successors and assigns permitted hereby and, to the
extent expressly contemplated hereby, the Indemnitees) any legal or equitable
right, remedy or claim under or by reason of this Agreement.

         (b)  Any Lender may assign to one or more Eligible Assignees all or a
portion of its rights and obligations under this Agreement (including all or a
portion of its Commitment and Loans (including for purposes of this subsection
(b), participations in LOC Obligations and in Swingline Loans) at the time owing
to it); provided that (i) except in the case of an assignment of the entire
remaining amount of the assigning Lender's Commitment and Loans at the time
owing to it or in the case of an assignment to a Lender or an Affiliate of a
Lender or an Approved Fund, the aggregate amount of the Commitment (which for
this purpose includes Loans outstanding thereunder) subject to each such
assignment, determined as of the date the assignment and acceptance agreement
with respect to such assignment (the "Assignment and Acceptance") is delivered
to the Administrative Agent, shall not be less than $1,000,000 unless the
Administrative Agent otherwise consents (each such consent not to be
unreasonably withheld or delayed), (ii) each partial assignment shall be made as
an assignment of a proportionate part of all the assigning Lender's rights and
obligations under this Agreement with respect to the Loans or the Commitment
assigned, except that this clause (ii) shall not apply to rights in respect of
outstanding Swingline Loans, and (iii) the parties to each assignment shall
execute and deliver to the Administrative Agent an Assignment and Acceptance,
together with a processing and recordation fee of $3,500. Subject to acceptance
and recording thereof by the Administrative Agent pursuant to subsection (c) of
this Section, from and after the effective date specified in each Assignment and
Acceptance, the Eligible Assignee thereunder shall be a party hereto and, to the
extent of the interest assigned by such Assignment and Acceptance, have the
rights and obligations of a Lender under this Agreement, and the assigning
Lender thereunder shall, to the extent of the interest assigned by such
Assignment and Acceptance, be released from its obligations under this Agreement
(and, in the case of an Assignment and Acceptance covering all of the assigning
Lender's rights and obligations under this Agreement, such Lender shall cease to
be a party hereto but shall continue to be entitled to the benefits of Sections
12.5 and 12.9). Upon request, the Borrower (at its expense) shall execute and
deliver new or replacement Notes to the assigning Lender and the assignee
Lender. Any assignment or transfer by a Lender of rights or obligations under
this Agreement that does not comply with this subsection shall be treated for
purposes of this Agreement as a sale by such Lender of a participation in such
rights and obligations in accordance with subsection (d) of this Section.

         (c)  The Administrative Agent, acting solely for this purpose as an
Administrative Agent of the Borrower, shall maintain at its office in Charlotte,
North Carolina a copy of each Assignment and Acceptance delivered to it and a
register for the recordation of the names and addresses of the Lenders, and the
Commitments of, and principal amount of the Loans and LOC Obligations owing to,
each Lender pursuant to the terms hereof from time to time (the "Register"). The
entries in the Register shall be conclusive, and the Borrower, the
Administrative Agent and the Lenders may treat each Person whose name is
recorded in the Register pursuant to the terms hereof as a Lender hereunder for
all purposes of this Agreement, notwithstanding notice to the contrary. The
Register shall be available for inspection by the Borrower and any Lender, at
any reasonable time and from time to time upon reasonable prior notice.

                                       73
<PAGE>
         (d)  Any Lender may, without the consent of, or notice to, the Borrower
or the Administrative Agent, sell participations to one or more banks or other
entities (a "Participant") in all or a portion of such Lender's rights and/or
obligations under this Agreement (including all or a portion of its Commitment
and/or the Loans (including such Lender's participations in LOC Obligations
and/or Swingline Loans) owing to it); provided that (i) such Lender's
obligations under this Agreement shall remain unchanged, (ii) such Lender shall
remain solely responsible to the other parties hereto for the performance of
such obligations and (iii) the Borrower, the Administrative Agent and the other
Lenders shall continue to deal solely and directly with such Lender in
connection with such Lender's rights and obligations under this Agreement. Any
agreement or instrument pursuant to which a Lender sells such a participation
shall provide that such Lender shall retain the sole right to enforce this
Agreement and to approve any amendment, modification or waiver of any provision
of this Agreement; provided that such agreement or instrument may provide that
such Lender will not, without the consent of the Participant, agree to any
amendment, waiver or other modification that would (i) postpone any date upon
which any payment of money is scheduled to be paid to such Participant, (ii)
reduce the principal, interest, fees or other amounts payable to such
Participant or (iii) release all or substantially all of the Guarantors from
their obligations under the Credit Documents. Subject to subsection (e) of this
Section, the Borrower agrees that each Participant shall be entitled to the
benefits of Sections 3.10 to the same extent as if it were a Lender and had
acquired its interest by assignment pursuant to subsection (b) of this Section.
To the extent permitted by law, each Participant also shall be entitled to the
benefits of Section 12.2 as though it were a Lender, provided such Participant
agrees to be subject to Section 3.14 as though it were a Lender.

         (e)  A Participant shall not be entitled to receive any greater payment
under Section 3.10 than the applicable Lender would have been entitled to
receive with respect to the participation sold to such Participant, unless the
sale of the participation to such Participant is made with the Borrower's prior
written consent. A Participant that would be a foreign Lender if it were a
Lender shall not be entitled to the benefits of Section 3.10 unless the Borrower
is notified of the participation sold to such Participant and such Participant
agrees, for the benefit of the Borrower, to comply with Section 3.10(d) as
though it were a Lender.

         (f)  Any Lender may at any time pledge or assign a security interest in
all or any portion of its rights under this Agreement (including under its
Notes, if any) to secure obligations of such Lender, including any pledge or
assignment to secure obligations to a Federal Reserve Bank; provided that no
such pledge or assignment shall release a Lender from any of its obligations
hereunder or substitute any such pledgee or assignee for such Lender as a party
hereto.

         (g)  If the consent of the Borrower to an assignment or to an Eligible
Assignee is required hereunder (including a consent to an assignment which does
not meet the minimum assignment threshold specified in clause (i) of the proviso
to the first sentence of Section 12.3(b), the Borrower shall be deemed to have
given its consent five Business Days after the date notice thereof has been
delivered by the assigning Lender (through the Administrative Agent) unless such
consent is expressly refused by the Borrower prior to such fifth Business Day.

         (h)  Notwithstanding anything to the contrary contained herein, if at
any time Bank of America assigns all of its Commitment and Loans pursuant to
subsection (b) above, Bank of America may, (i) upon 30 days' notice to the
Borrower and the Lenders, resign as Issuing Lender and/or (ii) upon 5 Business
Days' notice to the Borrower, resign as Swingline Lender. In the event of any
such resignation as Issuing Lender or as Swingline Lender, the Borrower shall be
entitled to appoint from among the Lenders a successor Issuing Lender or
Swingline Lender hereunder; provided, however, that no failure by

                                       74
<PAGE>
the Borrower to appoint any such successor shall affect the resignation of Bank
of America as Issuing Lender or as Swingline Lender, as the case may be. Bank
of America shall retain all the rights and obligations of the Issuing Lender
hereunder with respect to all Letters of Credit outstanding as of the effective
date of its resignation as Issuing Lender and all LOC Obligations with respect
thereto (including the right to require the Lenders to make Prime Rate Loans or
fund participations in Letters of Credit pursuant to Section 2.6(c)). If Bank
of America resigns as Swingline Lender, it shall retain all the rights of the
Swingline Lender provided for hereunder with respect to Swingline Loans made by
it and outstanding as of the effective date of such resignation, including the
right to require the Lenders to make Prime Rate Loans or fund participations in
outstanding Swingline Loans pursuant to Section 2.7.

         12.4     No Waiver; Remedies Cumulative.

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

         12.5     Payment of Expenses; Indemnity, etc.

         (a)  Payment of Expenses. The Borrower agrees to pay all reasonable
out-of-pocket costs and expenses (including, without limitation, expenses
incurred in connection with due diligence) of the Agents and the Lenders in
connection with the negotiation, preparation, execution and delivery,
administration, waiver, modification and enforcement of this Agreement and the
other Credit Documents and the documents and instruments referred to therein
(including, without limitation, the reasonable fees and disbursements of counsel
for the Agents and each of the Lenders and the reasonable fees and expenses of
any financial consultant retained by the Agents and the Lenders).

         (b)  Indemnity. Whether or not the transactions contemplated hereby are
consummated, the Borrower agrees to indemnify, save and hold harmless each
Agent, each Lender and their respective Affiliates, directors, officers,
employees, counsel, agents and attorneys-in-fact (collectively the
"Indemnitees") from and against: (a) any and all claims, demands, actions or
causes of action that are asserted against any Indemnitee by any Person (other
than either Agent or any Lender) relating directly or indirectly to a claim,
demand, action or cause of action that such Person asserts or may assert against
any Credit Party, any Affiliate of any Credit Party or any of their respective
officers or directors; (b) any and all claims, demands, actions or causes of
action that may at any time (including at any time following repayment of the
Revolving Obligations and the resignation or removal of either Agent or the
replacement of any Lender) be asserted or imposed against any Indemnitee,
arising out of or relating to, the Credit Documents, any predecessor Credit
Documents, the Commitments, the use or contemplated use of the proceeds of any
Extension of Credit, or the relationship of any Credit Party, the Agents and the
Lenders under this Agreement or any other Credit Document; (c) any
administrative or investigative proceeding by any Governmental Authority arising
out of or related to a claim, demand, action or cause of action described in
subsection (a) or (b) above; and (d) any and all liabilities (including
liabilities under indemnities), losses, costs or expenses (including reasonable
fees and costs of counsel) that any

                                       75
<PAGE>
Indemnitee suffers or incurs as a result of the assertion of any foregoing
claim, demand, action, cause of action or proceeding, or as a result of the
preparation of any defense in connection with any foregoing claim, demand,
action, cause of action or proceeding, in all cases, whether or not arising out
of the negligence of an Indemnitee, and whether or not an Indemnitee is a party
to such claim, demand, action, cause of action or proceeding (all the
foregoing, collectively, the "Indemnified Liabilities"); provided that no
Indemnitee shall be entitled to indemnification for any claim caused by its own
gross negligence or willful misconduct or for any loss asserted against it by
another Indemnitee. The agreements in this Section shall survive the
termination of the Commitments and repayment of all the other Obligations.

         12.6     Amendments, Waivers and Consents.

         Neither this Agreement nor any other Credit Document nor any of the
terms hereof or thereof may be amended, changed, waived, discharged or
terminated unless such amendment, change, waiver, discharge or termination is in
writing entered into by, or approved in writing by, the Required Lenders and the
Credit Parties, provided, however, that:

         (a)  without  the consent of each Lender affected thereby, neither this
         Agreement nor any of the other Credit Documents may be amended to

                     (i)    extend the final maturity of any Loan, or any
              portion thereof; or extend the time of payment of any
              reimbursement obligation, or any portion thereof, arising from
              drawings under Letters of Credit;

                     (ii)   reduce the rate or extend the time of payment of
              interest thereon or fees hereunder (other than as a result of
              waiving the applicability of any increase in interest rates or
              Fees after the occurrence of an Event of Default or on account
              of a failure to deliver financial statements on a timely
              basis),

                     (iii)  reduce or waive the principal amount of any Loan, or
              any portion thereof, or reduce or waive the principal amount

                     (iv)   increase the Commitment of a Lender over the amount
              thereof in effect (it being understood and agreed that a
              waiver of any Default or Event of Default shall not constitute
              an increase in the Commitment of any Lender),

                     (v)    except as the result of or in connection with a
              dissolution, merger or disposition of a Credit Party permitted
              by this Agreement, release the Borrower or all or
              substantially all of the Credit Parties from its or their
              obligations under the Credit Documents,

                     (vi)   except as the result of or in  connection  with a
              Divestiture  permitted  under this Agreement, release all or
              substantially all of the collateral,

                     (vii)  amend, modify or waive any provision of this Section
              12.6 or Section 3.10, 3.13, 3.14, 3.15, 10.1(a), 12.2, 12.3,
              12.5 or 12.9,

                     (viii) reduce any percentage specified in, or otherwise
              modify, the  definition of Required Lenders, or

<PAGE>
                     (ix)   consent to the assignment or transfer by the
              Borrower or any Guarantor of any of its rights and obligations
              under (or in respect of) the Credit  Documents except as permitted
              thereby;

         (b)  without the consent of the Agents, no provision of Section 11 may
         be amended; and

         (c)  without the consent of the Issuing  Lender,  no provision of
         Section 2.1(b), 2.2(a)(ii), 2.6 or 3.5(a)(ii) may be amended.

         Notwithstanding the fact that the consent of all the Lenders is
required in certain circumstances as set forth above, (x) each Lender is
entitled to vote as such Lender sees fit on any bankruptcy reorganization plan
that affects the Loans, and each Lender acknowledges that the provisions of
Section 1126(c) of the Bankruptcy Code supersede the unanimous consent
provisions set forth herein and (y) the Required Lenders may consent to allow a
Credit Party to use cash collateral in the context of a bankruptcy or insolvency
proceeding.

         12.7     Counterparts.

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

making proof of this Agreement to produce or account for more than one such
counterpart.

         12.8     Headings.

this Agreement, the making of the Loans, the issuance of the Letters of Credit,
the repayment of the Loans, LOC Obligations and other obligations under the
Credit Documents and the termination of the Commitments hereunder, and all
representations and warranties made by the Credit Parties herein shall survive

         12.10    Governing Law; Submission to Jurisdiction; Venue.

         (a)  THIS AGREEMENT AND THE OTHER CREDIT DOCUMENTS AND THE RIGHTS AND

WHETHER FOUNDED IN CONTRACT OR TORT OR OTHERWISE; AND EACH PARTY HEREBY AGREES
AND CONSENTS THAT ANY SUCH CLAIM, DEMAND, ACTION OR CAUSE OF ACTION SHALL BE
DECIDED BY COURT TRIAL WITHOUT A JURY, AND THAT ANY PARTY TO THIS CREDIT
AGREEMENT MAY FILE AN ORIGINAL COUNTERPART OR A COPY OF THIS SECTION WITH ANY
COURT AS WRITTEN EVIDENCE OF THE CONSENT OF THE SIGNATORIES HERETO TO THE
WAIVER OF THEIR RIGHT TO TRIAL BY JURY.

         12.11    Severability.

         If any provision of any of the Credit Documents is determined to be
illegal, invalid or unenforceable, such provision shall be fully severable and
the remaining provisions shall remain in full force and effect and shall be
construed without giving effect to the illegal, invalid or unenforceable
provisions.

         12.12    Entirety.

         This Agreement together with the other Credit Documents represent the
entire agreement of the parties hereto and thereto, and supersede all prior
agreements and understandings, oral or written, if any, including any commitment
letters or correspondence relating to the Credit Documents or the transactions
contemplated herein and therein.

         12.13    Binding Effect; Termination.

         (a)  This Agreement shall become effective at such time on or after the
Closing Date when it shall have been executed by the Borrower, the Guarantors
and the Agents, and the Administrative Agent shall have received copies hereof
(telefaxed or otherwise) which, when taken together, bear the signatures of each
Lender, and thereafter this Agreement shall be binding upon and inure to the
benefit of the Borrower, the Guarantors, the Agents and each Lender and their
respective successors and assigns.

         (b)  The term of this Agreement shall commence on the effective date
pursuant to subsection (a) above and shall continue until no Loans, LOC
Obligations or any other amounts payable hereunder or under any of the other
Credit Documents shall remain outstanding and until all of the Commitments
hereunder shall have expired or been terminated.

         12.14    Confidentiality.

         Each of the Agents and the Lenders agrees to maintain the
confidentiality of the Information (as defined below), except that Information
may be disclosed (a) to its and its Affiliates' directors, officers, employees
and agents, including accountants, legal counsel and other advisors (it being
understood that the Persons to whom such disclosure is made will be informed of
the confidential nature of such Information and instructed to keep such
Information confidential); (b) to the extent requested by any regulatory
authority; (c) to the extent required by applicable laws or regulations or by
any subpoena or similar legal process; (d) to any other party to this Credit
Agreement; (e) in connection with the exercise

                                       78
<PAGE>
of any remedies hereunder or any suit, action or proceeding relating to this
Credit Agreement or the enforcement of rights hereunder; (f) subject to an
agreement containing provisions substantially the same as those of this
Section, to (i) any Eligible Assignee of or Participant in, or any prospective
Eligible Assignee of or Participant in, any of its rights or obligations under
this Credit Agreement or (ii) any direct or indirect contractual counterparty
or prospective counterparty (or such contractual counterparty's or prospective
counterparty's professional advisor) to any credit derivative transaction
relating to obligations of the Borrower; (g) with the consent of the Borrower;
(h) to the extent such Information (i) becomes publicly available other than as
a result of a breach of this Section or (ii) becomes available to any Agent or
any Lender on a nonconfidential basis from a source other than the Borrower; or
(i) to the National Association of Insurance Commissioners or any other similar
organization or any nationally recognized rating agency that requires access to
information about a Lender's or its Affiliates' investment portfolio in
connection with ratings issued with respect to such Lender or its Affiliates.
For the purposes of this Section, "Information" means all information received
from the Borrower relating to the Borrower or its business, other than any such
information that is available to any Agent or any Lender on a nonconfidential
basis prior to disclosure by the Borrower; provided that, in the case of
information received from the Borrower after the Closing Date, such information
is clearly identified in writing at the time of delivery as confidential. Any
Person required to maintain the confidentiality of Information as provided in
this Section shall be considered to have complied with its obligation to do so
if such Person has exercised the same degree of care to maintain the
confidentiality of such Information as such Person would accord to its own
confidential information.

         12.15    Source of Funds.

         Each of the Lenders hereby represents and warrants to the Borrower that
at least one of the following statements is an accurate representation as to the
source of funds to be used by such Lender in connection with the financing
hereunder:

                  (a)  no part of such funds constitutes assets allocated to any
         separate account maintained by such Lender in which any employee
         benefit plan (or its related trust) has any interest;

                  (b)  to the extent that any part of such funds constitutes
         assets allocated to any separate account maintained by such Lender,
         such Lender has disclosed to the Borrower the name of each employee
         benefit plan whose assets in such account exceed 10% of the total
         assets of such account as of the date of such purchase (and, for
         purposes of this subsection (b), all employee benefit plans maintained
         by the same employer or employee organization are deemed to be a single
         plan);

                  (c)  to the extent that any part of such funds constitutes
         assets of an insurance company's general account, such insurance
         company has complied with all of the requirements of the regulations
         issued under Section 401(c)(1)(A) of ERISA or such insurance company
         meets the requirements of Department of Labor Exemption 95-60; or

                  (d)  such funds constitute assets of one or more specific
         benefit plans which such Lender has identified in writing to the
         Borrower.

As used in this Section 12.15, the terms "employee benefit plan" and "separate
account" shall have the respective meanings assigned to such terms in Section 3
of ERISA.

         12.16    Conflict.

         To the extent that there is a conflict or inconsistency between any
provision hereof, on the one hand, and any provision of any Credit Document, on
the other hand, this Agreement shall control. To the extent that there is a
conflict or inconsistency between any provision of any Credit Document, on the
one hand, and any provision of the Final DIP Financing Order, on the other hand,
the Final DIP Financing Order shall control.

         12.17    Limitation on Liability.

         NO CLAIM MAY BE MADE BY THE ADMINISTRATIVE AGENT, ANY CREDIT PARTY, ANY
LENDER OR OTHER PERSON AGAINST THE ADMINISTRATIVE AGENT, ANY LENDER, ANY CREDIT
PARTY OR THE AFFILIATES, DIRECTORS, OFFICERS, OFFICERS, EMPLOYEES, OR AGENTS OF
ANY OF THEM FOR ANY SPECIAL, INDIRECT, CONSEQUENTIAL OR PUNITIVE DAMAGES IN
RESPECT OF ANY CLAIM FOR BREACH OF CONTRACT OR ANY OTHER THEORY OF LIABILITY
ARISING OUT OF OR RELATED TO THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR
ANY OTHER CREDIT DOCUMENT, OR ANY ACT, OMISSION OR EVENT OCCURRING IN CONNECTION
THEREWITH, AND THE CREDIT PARTIES, THE ADMINISTRATIVE AGENT AND EACH LENDER
HEREBY WAIVE, RELEASE AND AGREE NOT TO SUE UPON ANY CLAIM FOR SUCH DAMAGES,
WHETHER OR NOT ACCRUED AND WHETHER OR NOT KNOWN OR SUSPECTED TO EXIST IN ITS
FAVOR.

         SUBJECT TO THE RIGHT OF THE STATUTORY COMMITTEE AND ANY OTHER PARTY IN
INTEREST TO PURSUE SUCH A CLAIM, WHICH IS HEREBY CONFERRED FOR THE PERIOD SET
FORTH BELOW, EACH OF THE CREDIT PARTIES HEREBY WAIVES ANY AND ALL CLAIMS OF ANY

THE PRE-PETITION LENDERS THAT AROSE PRIOR TO THE FILING DATE, INCLUDING, BUT NOT
LIMITED TO, CLAIMS FOR PREFERENCE, FRAUDULENT CONVEYANCE, OR ANY CLAIMS
ATTACKING THE PERFECTION, VALIDITY OR ENFORCEABILITY OF THE SECURITY INTERESTS,
MORTGAGES OR LIENS GRANTED IN CONNECTION WITH THE PRE-PETITION CREDIT FACILITY.
THIS WAIVER SHALL BE BINDING ON ANY CHAPTER 7 OR CHAPTER 11 TRUSTEE, EXAMINER,
OR COURT APPOINTED COMMITTEE PURSUANT TO SECTION 1102 OF THE BANKRUPTCY CODE,
UPON THE EXPIRATION OF NINETY (90) DAYS FROM THE FILING DATE, UNLESS AN ACTION
OR PROCEEDING HAS BEEN INSTITUTED BY SUCH ENTITY. THE CREDIT PARTIES' WAIVER
UNDER THIS SECTION SHALL BE IMMEDIATELY BINDING ON ALL OTHER ENTITIES.
