for the account of the Borrowers on a joint and several basis on any Business
Day from the Closing Date through but not including the date which is five (5)
Business Days prior to the Revolving Credit Maturity Date in such form as may be
approved from time to time by the Issuing Lender; provided, that the Issuing
Lender shall have no obligation to issue any Letter of Credit if, after giving
effect to such issuance, (i) the L/C Obligations would exceed the L/C Commitment
or (ii) the sum of (A) the L/C Obligations at such time plus (B) the aggregate

Lender and to the extent not inconsistent therewith, the laws of the State of
New York. The Issuing Lender shall not at any time be obligated to issue any
Letter of Credit hereunder if such issuance would conflict with, or cause the
Issuing Lender or any L/C Participant to exceed any limits imposed by, any
Applicable Law. References herein to "issue" and derivations thereof with
respect to Letters of Credit shall also include extensions or modifications of
any Existing Letters of Credit, unless the context otherwise requires.

        SECTION 3.2    Procedure for Issuance of Letters of Credit.     The
Borrowers may from time to time request that the Issuing Lender issue a Letter
of Credit by delivering to the Issuing Lender at the Administrative Agent's
Office an Application therefor, completed to the satisfaction of the Issuing
Lender, and such other certificates, documents and other papers and information
as the Issuing Lender may request. Upon receipt of any Application, the Issuing
Lender shall process such Application and the certificates, documents and other
papers and information delivered to it in connection therewith in accordance
with its customary procedures and shall, subject to Section 3.1 and Article VI
hereof, promptly issue the Letter of Credit requested thereby (but in no event
shall the Issuing Lender be

23

--------------------------------------------------------------------------------

required to issue any Letter of Credit earlier than three (3) Business Days
after its receipt of the Application therefor and all such other certificates,
documents and other papers and information relating thereto) by issuing the
original of such Letter of Credit to the beneficiary thereof or as otherwise may
be agreed by the Issuing Lender and the Borrowers. The Issuing Lender shall
promptly furnish to the Borrowers a copy of such Letter of Credit and promptly
notify each Lender of the issuance and upon request by any Lender, furnish to
such Lender a copy of such Letter of Credit and the amount of such Lender's L/C
Participation therein.

        SECTION 3.3    Commissions and Other Charges.     

        (a)  The Borrowers shall pay to the Administrative Agent, for the
account of the Issuing Lender and the L/C Participants, a letter of credit
commission with respect to each Letter of Credit in an amount equal to the
product of (i) the face amount of such Letter of Credit times (ii) an annual
percentage equal to the Applicable Margin with respect to LIBOR Rate Loans in
effect on the date of issuance of such Letter of Credit. Such commission shall
be payable quarterly in arrears on the last Business Day of each calendar
quarter and on the Revolving Credit Maturity Date.

        (b)  In addition to the foregoing commission, the Borrowers shall pay
the Issuing Lender an issuance fee of 0.125% per annum on the face amount of
each Letter of Credit, payable quarterly in arrears on the last Business Day of
each calendar quarter and on the Revolving Credit Maturity Date; provided, that
such issuance fee shall not be payable with respect to the Existing Letters of
Credit.

        (c)  The Borrowers shall also pay all normal costs and expenses of the
Issuing Lender in connection with the issuance, transfer or other administration
of the Letters of Credit.

        (d)  The Administrative Agent shall, promptly following its receipt
thereof, distribute to the Issuing Lender and the L/C Participants all
commissions received by the Administrative Agent in accordance with their
respective Revolving Credit Commitment Percentages.

        SECTION 3.4    L/C Participations.     

        (a)  The Issuing Lender irrevocably agrees to grant and hereby grants to
each L/C Participant, and, to induce the Issuing Lender to issue Letters of
Credit hereunder, each L/C Participant irrevocably agrees to accept and purchase
and hereby accepts and purchases from the Issuing Lender, on the terms and
conditions hereinafter stated, for such L/C Participant's own account and risk
an undivided interest equal to such L/C Participant's Revolving Credit
Commitment Percentage in the Issuing Lender's obligations and rights under each
Letter of Credit and the amount of each draft paid by the Issuing Lender
thereunder. Each L/C Participant unconditionally and irrevocably agrees with the
Issuing Lender that, if a draft is paid under any Letter of Credit for which the
Issuing Lender is not reimbursed in full by the Borrowers in accordance with the
terms of this Agreement, such L/C Participant shall pay to the Issuing Lender
upon demand at the Issuing Lender's address for notices specified herein an
amount equal to such L/C Participant's Revolving Credit Commitment Percentage of
the amount of such draft, or any part thereof, which is not so reimbursed.

        (b)  Upon becoming aware of any amount required to be paid by any L/C
Participant to the Issuing Lender pursuant to Section 3.4(a) in respect of any
unreimbursed portion of any payment made by the Issuing Lender under any Letter
of Credit, the Issuing Lender shall notify each L/C Participant of the amount
and due date of such required payment and such L/C Participant shall pay to the
Issuing Lender the amount specified on the applicable due date. If any such
amount is paid to the Issuing Lender after the date such payment is due, such
L/C Participant shall pay to the Issuing Lender on demand, in addition to such
amount, the product of (i) such amount, times (ii) the daily average Federal
Funds Rate as determined by the Administrative Agent during the period from and
including the date such payment is due to the date on which such payment is
immediately available to the Issuing Lender, times (iii) a fraction the
numerator of which is the number of days that elapse during such period and the
denominator of which is 360. A certificate of the Issuing Lender with respect to
any

24

--------------------------------------------------------------------------------

amounts owing under this Section 3.4(b) shall be conclusive in the absence of
manifest error. With respect to payment to the Issuing Lender of the
unreimbursed amounts described in this Section 3.4(b), if the L/C Participants
receive notice that any such payment is due (A) prior to 1:00 p.m. (Charlotte
time) on any Business Day, such payment shall be due that Business Day, and (B)
after 1:00 p.m. (Charlotte time) on any Business Day, such payment shall be due
on the following Business Day.

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

        SECTION 3.5    Reimbursement Obligation of the Borrowers.     In the
event of any drawing under any Letter of Credit, the Borrowers jointly and
severally agree to reimburse (either with the proceeds of a Revolving Credit
Loan as provided for in this Section 3.5 or with funds from other sources), in
same day funds, the Issuing Lender on each date on which the Issuing Lender
notifies the Borrowers of the date and amount of a draft paid under any Letter
of Credit for the amount of (a) such draft so paid and (b) any amounts referred
to in Section 3.3(c) incurred by the Issuing Lender in connection with such
payment. Unless the Borrowers shall immediately notify the Issuing Lender that
the Borrowers intend to reimburse the Issuing Lender for such drawing from other
sources or funds, the Borrowers shall be deemed to have timely given a Notice of
Revolving Credit/Swingline Borrowing to the Administrative Agent requesting that
the Lenders make a Revolving Credit Loan bearing interest at the Base Rate on
such date in the amount of (a) such draft so paid and (b) any amounts referred
to in Section 3.3(c) incurred by the Issuing Lender in connection with such
payment, and the Lenders shall make a Revolving Credit Loan bearing interest at
the Base Rate in such amount, the proceeds of which shall be applied to
reimburse the Issuing Lender for the amount of the related drawing and costs and
expenses. Each Lender acknowledges and agrees that its obligation to fund a
Revolving Credit Loan in accordance with this Section 3.5 to reimburse the
Issuing Lender for any draft paid under a Letter of Credit is absolute and
unconditional and shall not be affected by any circumstance whatsoever,
including, without limitation, non-satisfaction of the conditions set forth in
Section 2.3(a) or Article VI. If the Borrowers have elected to pay the amount of
such drawing with funds from other sources and shall fail to reimburse the
Issuing Lender as provided above, the unreimbursed amount of such drawing shall
bear interest at the rate which would be payable on any outstanding Base Rate
Loans which were then overdue from the date such amounts become payable (whether
at stated maturity, by acceleration or otherwise) until payment in full.

        SECTION 3.6    Obligations Absolute.     The obligations of the
Borrowers under this Article III (including without limitation the Reimbursement
Obligation) shall be irrevocable, absolute and unconditional under any and all
circumstances and irrespective of any set-off, counterclaim or defense to
payment which the Borrowers may have or have had against the Issuing Lender or
any beneficiary of a Letter of Credit. The Borrowers also agree with the Issuing
Lender that the Issuing Lender and the L/C Participants shall not be responsible
for, and the Reimbursement Obligation of the Borrowers under Section 3.5 shall
not be affected by, among other things, the validity or genuineness of this
Agreement, any documents or of any endorsements thereon, even though such
documents shall in fact prove to be invalid, fraudulent or forged, or any
dispute between or among the Borrowers and any beneficiary of any Letter of
Credit or any other party to which such Letter of Credit may be transferred or
any claims whatsoever of a Borrower against any beneficiary of such Letter of
Credit or any such transferee or the application or misapplication of the
proceeds or any Letter of Credit by any beneficiary thereunder. The Issuing
Lender shall not be liable for any error, omission, interruption or

25

--------------------------------------------------------------------------------

delay in transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit, except for errors or
omissions caused by the Issuing Lender's gross negligence or willful misconduct.
The Borrowers agree that any action taken or omitted by the Issuing Lender under
or in connection with any Letter of Credit or the related drafts or documents,
if done in the absence of gross negligence or willful misconduct and in
accordance with the standards of care specified in the Uniform Customs and, to
the extent not inconsistent therewith, the UCC as in effect in the State of New
York from time to time shall be binding on the Borrowers and shall not result in
any liability of the Issuing Lender or any L/C Participant to the Borrowers. The
responsibility of the Issuing Lender to the Borrowers in connection with any
draft presented for payment under any Letter of Credit shall, in addition to any
payment obligation expressly provided for in such Letter of Credit, be limited
to determining that the documents (including each draft) delivered under such
Letter of Credit in connection with such presentment are in conformity with such
Letter of Credit.

        SECTION 3.7    Effect of Application.     To the extent that any
provision of any Application related to any Letter of Credit is inconsistent
with the provisions of this Article III, the provisions of this Article III
shall apply.

written notice of such event and the amount of the corresponding prepayment to
the Administrative Agent and upon receipt of such notice, the Administrative
Agent shall promptly so notify the Lenders. Each mandatory prepayment of the
Term Loans under Section 4.4(b) shall be applied as follows: (i) first, to
reduce the outstanding principal balance of the Term Loans on a pro rata basis
between the

28

--------------------------------------------------------------------------------

Term A Loans and the Term B Loans and to reduce the remaining scheduled
principal installments of the Term Loans under Section 4.3 in inverse order of
maturity and (ii) second, to the extent of any excess, to reduce permanently the
Revolving Credit Commitment pursuant to Section 2.6(b).

        (c)    No Reborrowing of Term Loans.    Amounts prepaid under the Term
Loans pursuant to Section 4.3 or Section 4.4 may not be reborrowed and will
constitute a permanent reduction in the applicable Term Loan Commitment. Each
prepayment shall be accompanied by any amount required to be paid pursuant to
Section 5.9 hereof.

        SECTION 4.5    Term Notes.     Each Lender's Term A Loans and the
obligation of the Borrowers to repay such Term A Loans shall be evidenced by a
Term A Note, payable to the order of such Lender representing the Borrowers'
obligation to pay such Lender's Term A Loan Commitment in accordance with the
terms hereof. Each Lender's Term B Loans and the obligation of the Borrowers to
repay such Term B Loans shall be evidenced by a Term B Note, payable to the
order of such Lender representing the Borrowers' obligation to pay such Lender's
Term B Loan Commitment in accordance with the terms hereof. Each Term Note shall
bear interest on the unpaid principal amount thereof at the applicable interest
rate per annum specified in Section 5.1.

ARTICLE V

GENERAL LOAN PROVISIONS

        SECTION 5.1    Interest.     

        (a)    Interest Rate Options.    Subject to the provisions of this
Section 5.1, at the election of the Company on behalf of the Borrowers, the
aggregate principal balance of any Revolving Credit Note and any Term Loan Note
shall bear interest at (i) the Base Rate plus the Applicable Margin as set forth
in Section 5.1(c) or (ii) the LIBOR Rate plus the Applicable Margin as set forth
in Section 5.1(c); provided that the LIBOR Rate shall not be available until
three (3) Business Days after the Closing Date. The Swingline Note shall bear
interest at the Base Rate plus the Applicable Margin as set forth in Section
5.1(c). The Borrowers shall select the rate of interest and Interest Period, if
any, applicable to any Loan at the time a Notice of Revolving Credit/Swingline
Borrowing is given pursuant to Section 2.3(a) or a Notice of Term Loan Borrowing
is given pursuant to Section 4.2 or at the time a Notice of
Conversion/Continuation is given pursuant to Section 5.2. Each Loan or portion
thereof bearing interest based on the Base Rate (other than Swingline Loans)
shall be a "Base Rate Loan", each Loan or portion thereof bearing interest based
on the LIBOR Rate shall be a "LIBOR Rate Loan." Any Loan or any portion thereof
as to which the Borrowers have not duly specified an interest rate as provided
herein shall be deemed a Base Rate Loan.

        (b)    Interest Periods.    In connection with each LIBOR Rate Loan, the
Company on behalf of the Borrowers, by giving notice at the times described in
Section 5.1(a), shall elect an interest period (each, an "Interest Period") to
be applicable to such LIBOR Rate Loan, which Interest Period shall be a period
of one (1), two (2), three (3), or six (6) months with respect to each LIBOR
Rate Loan; provided that:

        (i)    the Interest Period shall commence on the date of advance of or
conversion to any LIBOR Rate Loan and, in the case of immediately successive
Interest Periods, each successive Interest Period shall commence on the date on
which the next preceding Interest Period expires;

        (ii)  if any Interest Period would otherwise expire on a day that is not
a Business Day, such Interest Period shall expire on the next succeeding
Business Day; provided, that if any Interest Period with respect to a LIBOR Rate
Loan would otherwise expire on a day that is not a Business Day but is a day of
the month after which no further Business Day occurs in such month, such
Interest Period shall expire on the next preceding Business Day;

29

--------------------------------------------------------------------------------

        (iii)  any Interest Period with respect to a LIBOR Rate Loan that begins
on the last Business Day of a calendar month (or on a day for which there is no
numerically corresponding day in the calendar month at the end of such Interest
Period) shall end on the last Business Day of the relevant calendar month at the
end of such Interest Period;

        (iv)  no Interest Period shall extend beyond the Revolving Credit
Termination Date, the Term A Loan Maturity Date or the Term B Loan Maturity
Date, as applicable, and Interest Periods shall be selected by the Borrowers so
as to permit the Borrowers to make mandatory reductions of the Revolving Credit
Commitment pursuant to Section 2.6(b) and the quarterly principal installment
payments pursuant to Section 4.3 without payment of any amounts pursuant to
Section 5.9; and

        (v)  there shall be no more than seven (7) Interest Periods in effect at
any time.

        (c)    Applicable Margin.    The Applicable Margin provided for in
Section 5.1(a) with respect to the Loans (the "Applicable Margin") shall be
based upon the Leverage Ratio as set forth in the table below and shall be
determined and adjusted quarterly on the date (each a "Calculation Date") ten
(10) Business Days after the date by which the Borrowers are required to provide
an Officer's Compliance Certificate for the most recently ended fiscal quarter
of the Borrowers and their Subsidiaries; provided, that with respect to the
period commencing on the Effective Date and ending on the next Calculation Date
to occur after the Effective Date, the calculation of the Applicable Margin
shall be based on the most recent Officer's Compliance Certificate received by
the Administrative Agent and Lenders prior to the Effective Date.
Notwithstanding the foregoing, if the Borrowers fail to provide the Officer's
Compliance Certificate as required by Section 8.2 for the most recently ended
fiscal quarter of the Borrowers and their Subsidiaries preceding the applicable
Calculation Date, the Applicable Margin from such Calculation Date shall be
based on Pricing Level 1 (as shown below) until such time as an appropriate
Officer's Compliance Certificate is provided, at which time the Pricing Level
shall be determined by reference to the Leverage Ratio as of the last day of the
most recently ended fiscal quarter of the Borrowers preceding such Calculation
Date. The Applicable Margin shall be effective from one Calculation Date until
the next Calculation Date. Any adjustment in the Applicable Margin shall be
applicable to all Extensions of Credit then existing or subsequently made or
issued.

        Notwithstanding the foregoing, the Leverage Ratios set forth in this
Section 5.1(c) are for pricing purposes only and shall not be deemed to permit
the Leverage Ratio to exceed the maximum amounts permitted under this Agreement.
The Applicable Margins set forth in this Section 5.1(c) represent base pricing
subject to increase as set forth in Section 5.1(d).

        (d)    Default Rate.    Subject to Section 12.3, at the discretion of
the Administrative Agent and Required Lenders upon the occurrence and during the
continuance of an Event of Default, (i) the

30

--------------------------------------------------------------------------------

Borrowers shall no longer have the option to request LIBOR Rate Loans or
Swingline Loans, (ii) all outstanding LIBOR Rate Loans shall bear interest at a
rate per annum two percent (2%) in excess of the rate then applicable to LIBOR
Rate Loans, as applicable, until the end of the applicable Interest Period and
thereafter at a rate equal to two percent (2%) in excess of the rate then
applicable to Base Rate Loans (calculated at the highest Applicable Margin), and
(iii) all outstanding Base Rate Loans and Swingline Loans shall bear interest at
a rate per annum equal to two percent (2%) in excess of the rate then applicable
to Base Rate Loans. Interest shall continue to accrue on the Notes after the
filing by or against any Borrower of any petition seeking any relief in
bankruptcy or under any act or law pertaining to insolvency or debtor relief,
whether state, federal or foreign.

        (e)    Interest Payment and Computation.    Interest on each Base Rate
Loan and Swingline Loans shall be payable in arrears on the last Business Day of
each calendar quarter commencing June 30, 2000; and interest on each LIBOR Rate
Loan shall be payable on the last day of each Interest Period applicable
thereto, and if such Interest Period extends over three (3) months, at the end
of each three (3) month interval during such Interest Period. Interest on LIBOR
Rate Loans and all fees payable hereunder shall be computed on the basis of a
360-day year and assessed for the actual number of days elapsed and interest on
Base Rate Loans shall be computed on the basis of a 365/66-day year and assessed
for the actual number of days elapsed.

        (f)    Maximum Rate.    In no contingency or event whatsoever shall the
aggregate of all amounts deemed interest hereunder or under any of the Notes
charged or collected pursuant to the terms of this Agreement or pursuant to any
of the Notes exceed the highest rate permissible under any Applicable Law which
a court of competent jurisdiction shall, in a final determination, deem
applicable hereto. In the event that such a court determines that the Lenders
have charged or received interest hereunder in excess of the highest applicable
rate, the rate in effect hereunder shall automatically be reduced to the maximum
rate permitted by Applicable Law and the Lenders shall at the Administrative
Agent's option (i) promptly refund to the Borrowers any interest received by
Lenders in excess of the maximum lawful rate or (ii) shall apply such excess to
the principal balance of the Obligations. It is the intent hereof that the
Borrowers not pay or contract to pay, and that neither the Administrative Agent
nor any Lender receive or contract to receive, directly or indirectly in any
manner whatsoever, interest in excess of that which may be paid by the Borrowers
under Applicable Law.

        SECTION 5.2    Notice and Manner of Conversion or Continuation of Loans.
    Provided that no Event of Default has occurred and is then continuing, the
Borrowers shall have the option to convert at any time following the third
Business Day after the Closing Date all or any portion of its outstanding Base
Rate Loans (other than Swingline Loans) in a principal amount equal to
$2,000,000 or any whole multiple of $500,000 in excess thereof into one or more
LIBOR Rate Loans and (b) upon the expiration of any Interest Period, (i) convert
all or any part of its outstanding LIBOR Rate Loans in a principal amount equal
to $1,000,000 or a whole multiple of $250,000 in excess thereof into Base Rate
Loans or (ii) continue such LIBOR Rate Loans as LIBOR Rate Loans. Whenever the
Borrowers desire to convert or continue Loans as provided above, the Company on
behalf of the Borrowers shall give the Administrative Agent irrevocable prior
written notice in the form attached as Exhibit F (a "Notice of
Conversion/Continuation") not later than 11:00 a.m. (Charlotte time) three (3)
Business Days before the day on which a proposed conversion or continuation of
such Loan is to be effective specifying (A) the Loans to be converted or
continued, and, in the case of any LIBOR Rate Loan to be converted or continued,
the last day of the Interest Period therefor specifying the Credit Facility to
which such Loan relates, (B) the effective date of such conversion or
continuation (which shall be a Business Day), (C) the principal amount of such
Loans to be converted or continued, and (D) the Interest Period to be applicable
to such converted or continued LIBOR Rate Loan. The Administrative Agent shall
promptly notify the Lenders of such Notice of Conversion/Continuation.

31

--------------------------------------------------------------------------------

        SECTION 5.3    Fees.     

        (a)    Commitment Fee.    Commencing on the Closing Date and continuing
through but excluding the Revolving Credit Maturity Date, the Borrowers shall
pay to the Administrative Agent, for the account of the Lenders, a
non-refundable commitment fee at a rate per annum equal to the rate set forth
below (the "Commitment Fee Rate") on the average daily unused portion of the
Revolving Credit Commitment (the outstanding principal balance of all Revolving
Credit Loans, Swingline Loans and L/C Obligations shall be considered usage).
The commitment fee shall be payable in arrears on the last Business Day of each
calendar quarter commencing June 30, 2000, and on the Revolving Credit Maturity
Date. Such commitment fee shall be distributed by the Administrative Agent to
the Lenders pro rata in accordance with the Lenders' respective Revolving Credit
Commitment Percentages. The Commitment Fee Rate provided for above shall equal
the percentage set forth below corresponding to the level at which the
Applicable Margin is determined in accordance with Section 5.1(c). Any change in
the applicable level at which Applicable Margin is determined shall result in a
corresponding and simultaneous change in the Commitment Fee Rate.

        (b)    Administrative Agent's and Other Fees.    In order to compensate
the Administrative Agent for structuring and syndicating the Loans and for its
obligations hereunder, the Borrowers agree to pay to the Administrative Agent,
for its account, the fees set forth in the separate fee letter agreement
executed by the Company, on behalf of itself and the other Borrowers, and the
Administrative Agent dated March 29, 2000.

        SECTION 5.4    Manner of Payment.     (a) Each payment by the Borrowers
on account of the principal of or interest on the Revolving Credit Loans or of
any fee, commission or other amounts (including the Reimbursement Obligation)
payable to the Lenders under this Agreement with respect to the Revolving Credit
Loans, the Letters of Credit or any Revolving Credit Note shall be made not
later than 1:00 p.m. (Charlotte time) on the date specified for payment under
this Agreement to the Administrative Agent at the Administrative Agent's Office
for the account of the Lenders having a Revolving Credit Commitment (other than
as set forth below) pro rata in accordance with their respective Revolving
Credit Commitment Percentages, (except as specified below) in Dollars, in
immediately available funds and shall be made without any set-off, counterclaim
or deduction whatsoever, (b) each payment to the Administrative Agent on account
of the principal of or interest on the Swingline Loans or of any fee, commission
or other amounts shall be made in like manner, except for the account of the
Swingline Lender, (c) each payment by the Borrowers on account of the principal
of or interest on the Term A Loans or of any fee, commission or other amounts
payable to the Lenders under this Agreement with respect to the Term A Loans or
any Term A Note shall be made in like manner, for the account of the Lenders
having a Term A Loan Commitment pro rata in accordance with their respective
Term A Loan Percentages and shall be made without any set-off, counterclaim or
deduction whatsoever, (d) each payment by the Borrowers on account of the
principal of or interest on the Term B Loans or of any fee, commission or other
amounts payable to the Lenders under this Agreement with respect to the Term B
Loans or any Term B Note shall be made in like manner, for the account of the
Lenders having a Term B Loan Commitment pro rata in accordance with their
respective Term B Loan Percentages and shall be made without any set-off,
counterclaim or

32

--------------------------------------------------------------------------------

deduction whatsoever and (e) any other amounts payable to the Lenders under this
Agreement shall be made in like manner pro rata based on its or their respective
share in the Obligation with respect to which such payment was received and
shall be made without any set-off, counterclaim or deduction whatsoever. Any
payment received after such time but before 2:00 p.m. (Charlotte time) on such
day shall be deemed a payment on such date for the purposes of Section 12.1, but
for all other purposes shall be deemed to have been made on the next succeeding
Business Day. Any payment received after 3:00 p.m. (Charlotte time) shall be
deemed to have been made on the next succeeding Business Day for all purposes.
Upon receipt by the Administrative Agent of each such payment, the
Administrative Agent shall distribute to each Lender at its address for notices
set forth herein its pro rata share of such payment in accordance with such
Lender's Revolving Credit Commitment Percentage, Term A Loan Percentage and/or
Term B Loan Percentage, as applicable (except as specified below) and shall wire
advice of the amount of such credit to each Lender. Each payment to the
Administrative Agent of the Issuing Lender's fees or L/C Participants'
commissions shall be made in like manner, but for the account of the Issuing
Lender or the L/C Participant, as the case may be. Each payment to the
Administrative Agent of the Administrative Agent's or Issuing Lender's fees or
expenses shall be made for the account of the Administrative Agent or Issuing
Lender, as the case may be, and each amount payable by the Borrowers to the
Swingline Lender with respect to the Swingline Note shall be made to the
Administrative Agent for the account of the Swingline Lender, and any amount
payable to any Lender under Sections 5.8, 5.9, 5.10, 5.11 or 14.2 shall be paid
to the Administrative Agent for the account of the applicable Lender. Subject to
Section 5.1(b)(ii) if any payment under this Agreement or any Note shall be
specified to be made upon a day which is not a Business Day, it shall be made on
the next succeeding day which is a Business Day and such extension of time shall
in such case be included in computing any interest if payable along with such
payment.

        SECTION 5.5    Crediting of Payments and Proceeds.     In the event that
the Borrowers shall fail to pay any of the Obligations when due and the
Obligations have been accelerated pursuant to Section 12.2, all payments
received by the Lenders upon the Notes and the other Obligations and all net
proceeds from the enforcement of the Obligations shall be applied first to all
expenses then due and payable by the Borrowers hereunder, then to all indemnity
obligations then due and payable by the Borrowers hereunder, then to all
Administrative Agent's and Issuing Lender's fees then due and payable, then to
all commitment and other fees and commissions then due and payable, then to
accrued and unpaid interest on the Swingline Note to the Swingline Lender, then
to the principal amount outstanding under the Swingline Note to the Swingline
Lender, then to accrued and unpaid interest on the other Notes and the
Reimbursement Obligation (pro rata in accordance with all such amounts due),
then to the principal amount of the other Notes and Reimbursement Obligation and
any termination payments due in respect of a Hedging Agreement with any Lender
(which such Hedging Agreement is permitted hereunder and required or requested
by the Required Lenders) (pro rata in accordance with all such amounts due) and
then to the cash collateral account described in Section 12.2(b) hereof to the
extent of any L/C Obligations then outstanding, then to any termination payments
due in respect of a Hedging Agreement with any Lender (which such Hedging
Agreement is permitted, but not required or requested by the Required Lenders),
in that order.

        SECTION 5.6    Adjustments.     If any Lender (a "Benefited Lender")
shall at any time receive any payment of all or part of the Obligations owing to
it, or interest thereon, or if any Lender shall at any time receive any
collateral in respect of the Obligations owing to it (whether voluntarily or
involuntarily, by set-off or otherwise) in a greater proportion than any such
payment to and collateral received by any other Lender, if any, in respect of
the Obligations owing to such other Lender, or interest thereon, such Benefited
Lender shall purchase for cash from the other Lenders such portion of each such
other Lender's Extensions of Credit, or shall provide such other Lenders with
the benefits of any such collateral, or the proceeds thereof, as shall be
necessary to cause such Benefited Lender to share the excess payment or benefits
of such collateral or proceeds ratably with each of the Lenders; provided, that
if all or any portion of such excess payment or benefits is thereafter recovered
from such

33

--------------------------------------------------------------------------------

Benefited Lender, such purchase shall be rescinded, and the purchase price and
benefits returned to the extent of such recovery, but without interest. The
Borrowers agree that each Lender so purchasing a portion of another Lender's
Extensions of Credit may exercise all rights of payment (including, without
limitation, rights of set-off) with respect to such portion as fully as if such
Lender were the direct holder of such portion.

        SECTION 5.7    Nature of Obligations of Lenders Regarding Extensions of
Credit; Assumption by the Administrative Agent.     The obligations of the
Lenders under this Agreement to make the Loans and issue or participate in
Letters of Credit are several and are not joint or joint and several. Unless the
Administrative Agent shall have received notice from a Lender prior to a
proposed borrowing date that such Lender will not make available to the
Administrative Agent such Lender's ratable portion of the amount to be borrowed
on such date (which notice shall not release such Lender of its obligations
hereunder), the Administrative Agent may assume that such Lender has made such
portion available to the Administrative Agent on the proposed borrowing date in
accordance with Sections 2.3(b) and 4.2, and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrowers on such date a
corresponding amount. If such amount is made available to the Administrative
Agent on a date after such borrowing date, such Lender shall pay to the
Administrative Agent on demand an amount, until paid, equal to the product of
(a) the amount not made available by such Lender in accordance with the terms
hereof, times (b) the daily average Federal Funds Rate during such period as
determined by the Administrative Agent, times (c) a fraction the numerator of
which is the number of days that elapse from and including such borrowing date
to the date on which such amount not made available by such Lender in accordance
with the terms hereof shall have become immediately available to the
Administrative Agent and the denominator of which is 360. A certificate of the
Administrative Agent with respect to any amounts owing under this Section 5.7
shall be conclusive, absent manifest error. If such Lender's Revolving Credit
Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as
applicable, of such borrowing is not made available to the Administrative Agent
by such Lender within three (3) Business Days after such borrowing date, the
Administrative Agent shall be entitled to recover such amount made available by
the Administrative Agent with interest thereon at the rate per annum applicable
to Base Rate Loans hereunder, on demand, from the Borrowers. The failure of any
Lender to make its Revolving Credit Commitment Percentage, Term A Loan
Percentage or Term B Loan Percentage, as applicable, of any Loan available shall
not relieve it or any other Lender of its obligation, if any, hereunder to make
its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B
Loan Percentage, as applicable, of such Loan available on such borrowing date,
but no Lender shall be responsible for the failure of any other Lender to make
its Revolving Credit Commitment Percentage, Term A Loan Percentage or Term B
Loan Percentage, as applicable, of such Loan available on the borrowing date.

        SECTION 5.8    Changed Circumstances.     

        (a)    Circumstances Affecting LIBOR Rate Availability.    If with
respect to any Interest Period the Administrative Agent or any Lender (after
consultation with Administrative Agent) shall determine that, by reason of
circumstances affecting the foreign exchange and interbank markets generally,
deposits in eurodollars, in the applicable amounts are not being quoted via Dow
Jones Market Screen 3750 or offered to the Administrative Agent or such Lender
for such Interest Period, then the Administrative Agent shall forthwith give
notice thereof to the Borrowers. Thereafter, until the Administrative Agent
notifies the Borrowers that such circumstances no longer exist, the obligation
of the Lenders to make LIBOR Rate Loans and the right of the Borrowers to
convert any Loan to or continue any Loan as a LIBOR Rate Loan shall be
suspended, and the Borrowers shall repay in full (or cause to be repaid in full)
the then outstanding principal amount of each such LIBOR Rate Loan together with
accrued interest thereon, on the last day of the then current Interest Period
applicable to such LIBOR Rate Loan or convert the then outstanding principal
amount of each such LIBOR Rate Loan to a Base Rate Loan as of the last day of
such Interest Period.

34

--------------------------------------------------------------------------------

        (b)    Laws Affecting LIBOR Rate Availability.    If, after the date
hereof, the introduction of, or any change in, any Applicable Law or any change
in the interpretation or administration thereof by any Governmental Authority,
central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by any Lender (or any of their respective
Lending Offices) with any request or directive (whether or not having the force
of law) of any such Governmental Authority, central bank or comparable agency,
shall make it unlawful or impossible for any of the Lenders (or any of their
respective Lending Offices) to honor its obligations hereunder to make or
maintain any LIBOR Rate Loan, such Lender shall promptly give notice thereof to
the Administrative Agent and the Administrative Agent shall promptly give notice
to the Borrowers and the other Lenders. Thereafter, until the Administrative
Agent notifies the Borrowers that such circumstances no longer exist, (i) the
obligations of the Lenders to make LIBOR Rate Loans and the right of the
Borrowers to convert any Loan or continue any Loan as a LIBOR Rate Loan shall be
suspended and thereafter the Borrowers may select only Base Rate Loans
hereunder, and (ii) if any of the Lenders may not lawfully continue to maintain
a LIBOR Rate Loan to the end of the then current Interest Period applicable
thereto as a LIBOR Rate Loan, the applicable LIBOR Rate Loan shall immediately
be converted to a Base Rate Loan for the remainder of such Interest Period.

        (c)    Increased Costs.    If, after the date hereof, the introduction
of, or any change in, any Applicable Law, or in the interpretation or
administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any of the Lenders (or any of their respective Lending Offices) with any
request or directive (whether or not having the force of law) of such
Governmental Authority, central bank or comparable agency:

        (i)    shall subject any of the Lenders (or any of their respective
Lending Offices) to any tax, duty or other charge with respect to any Note,
Letter of Credit or Application or shall change the basis of taxation of
payments to any of the Lenders (or any of their respective Lending Offices) of
the principal of or interest on any Note, Letter of Credit or Application or any
other amounts due under this Agreement in respect thereof (except for changes in
the rate of tax on the overall net income of any of the Lenders or any of their
respective Lending Offices imposed by the jurisdiction in which such Lender is
organized or is or should be qualified to do business or such Lending Office is
located); or

        (ii)  shall impose, modify or deem applicable any reserve (including,
without limitation, any imposed by the Board of Governors of the Federal Reserve
System), special deposit, insurance or capital or similar requirement against
assets of, deposits with or for the account of, or credit extended by any of the
Lenders (or any of their respective Lending Offices) or shall impose on any of
the Lenders (or any of their respective Lending Offices) or the foreign exchange
and interbank markets any other condition affecting any Note; and the result of
any of the foregoing is to increase the costs to any of the Lenders of
maintaining any LIBOR Rate Loan or issuing or participating in Letters of Credit
or to reduce the yield or amount of any sum received or receivable by any of the
Lenders under this Agreement or under the Notes in respect of a LIBOR Rate Loan
or Letter of Credit or Application, then such Lender shall promptly notify the
Administrative Agent, and the Administrative Agent shall promptly notify the
Borrowers of such fact and demand compensation therefor and, within fifteen (15)
days after such notice by the Administrative Agent, the Borrowers shall pay to
such Lender such additional amount or amounts as will compensate such Lender or
Lenders for such increased cost or reduction. The Administrative Agent will
promptly notify the Borrowers of any event of which it has knowledge which will
entitle such Lender to compensation pursuant to this Section 5.8(c); provided,
that the Administrative Agent shall incur no liability whatsoever to the Lenders
or the Borrowers in the event it fails to do so. The amount of such compensation
shall be determined, in the applicable Lender's sole discretion, based upon the
assumption that such Lender funded its Revolving Credit

35

--------------------------------------------------------------------------------

Commitment Percentage, Term A Loan Percentage or Term B Loan Percentage, as
applicable, of the LIBOR Rate Loans in the London interbank market and using any
reasonable attribution or averaging methods which such Lender deems appropriate
and practical. A certificate of such Lender setting forth the basis for
determining such amount or amounts necessary to compensate such Lender shall be
forwarded to the Borrowers through the Administrative Agent and shall be
conclusively presumed to be correct save for manifest error.

        SECTION 5.9    Indemnity.     The Borrowers hereby indemnify each of the
Lenders against any loss or expense which may arise or be attributable to each
Lender's obtaining, liquidating or employing deposits or other funds acquired to
effect, fund or maintain any Loan (a) as a consequence of any failure by the
Borrowers to make any payment when due of any amount due hereunder in connection
with a LIBOR Rate Loan, (b) due to any failure of the Borrowers to borrow on a
date specified therefor in a Notice of Borrowing or Notice of
Continuation/Conversion or make a prepayment after giving notice thereof to the
Administrative Agent or (c) due to any payment, prepayment or conversion of any
LIBOR Rate Loan on a date other than the last day of the Interest Period
therefor. The amount of such loss or expense shall be determined, in the
applicable Lender's sole discretion, based upon the assumption that such Lender
funded its Revolving Credit Commitment Percentage, Term A Loan Percentage or
Term B Loan Percentage, as applicable, of the LIBOR Rate Loans in the London
interbank market and using any reasonable attribution or averaging methods which
such Lender deems appropriate and practical. A certificate of such Lender
setting forth the basis for determining such amount or amounts necessary to
compensate such Lender shall be forwarded to the Borrowers through the
Administrative Agent and shall be conclusively presumed to be correct save for
manifest error.

either (a) the introduction of, or any change in, or in the interpretation of,
any Applicable Law or (b) compliance with any guideline or request from any
central bank or comparable agency or other Governmental Authority (whether or
not having the force of law), has or would have the effect of reducing the rate
of return on the capital of, or has affected or would affect the amount of
capital required to be maintained by, any Lender or any corporation controlling
such Lender as a consequence of, or with reference to the Commitments and other
commitments of this type, below the rate which the Lender or such other
corporation could have achieved but for such introduction, change or compliance,
then within five (5) Business Days after written demand by any such Lender, the
Borrowers shall pay to such Lender from time to time as specified by such Lender
additional amounts sufficient to compensate such Lender or other corporation for

withholdings and liabilities being hereinafter referred to as "Taxes"). If the
Borrowers shall be required by law to deduct or withhold any Taxes from or in
respect of any sum payable hereunder or under any Note or Letter of Credit to
any Lender or the Administrative Agent, (A) the sum payable shall be increased
as may be

36

--------------------------------------------------------------------------------

necessary so that after making all required deductions or withholdings
(including deductions or withholdings applicable to additional sums payable
under this Section 5.11) such Lender or the Administrative Agent (as the case
may be) receives an amount equal to the amount such party would have received
had no such deductions or withholdings been made, (B) the Borrowers shall make
such deductions or withholdings, (C) the Borrowers shall pay the full amount
deducted to the relevant taxing authority or other authority in accordance with
applicable law, and (D) the Borrowers shall deliver to the Administrative Agent

execution, delivery or registration of, or otherwise with respect to, this
Agreement, the Loans, the Letters of Credit, the other Loan Documents, or the
perfection of any rights or security interest in respect thereto (hereinafter
referred to as "Other Taxes").

        (c)    Indemnity.    The Borrowers shall indemnify each Lender and the
Administrative Agent for the full amount of Taxes and Other Taxes (including,
without limitation, any Taxes and Other Taxes imposed by any jurisdiction on
amounts payable under this Section 5.11) paid by such Lender or the
Administrative Agent (as the case may be) and any liability (including
penalties, interest and expenses) arising therefrom or with respect thereto,
whether or not such Taxes or Other Taxes were correctly or legally asserted.
Such indemnification shall be made within thirty (30) days from the date such
Lender or the Administrative Agent (as the case may be) makes written demand
therefor.

        (d)    Evidence of Payment.    Within thirty (30) days after the date of
any payment of Taxes or Other Taxes, the Borrowers shall furnish to the
Administrative Agent, at its address referred to in Section 14.1, the original
or a certified copy of a receipt evidencing payment thereof or other evidence of
payment satisfactory to the Administrative Agent.

        (e)    Delivery of Tax Forms.    Each Lender organized under the laws of
a jurisdiction other than the United States or any state thereof shall deliver
to the Borrowers, with a copy to the Administrative Agent, on the Closing Date
or concurrently with the delivery of the relevant Assignment and Acceptance, as
applicable, (i) two United States Internal Revenue Service Forms W-8ECI or Forms
W-8BEN, as applicable (or successor forms) properly completed and certifying in
each case that such Lender is entitled to a complete exemption from withholding
or deduction for or on account of any United States federal income taxes, and
(ii) an Internal Revenue Service Form W-8BEN or W-8ECI or successor applicable

with a copy to the Administrative Agent, a Form W-8BEN or W-8ECI, or successor
applicable forms or manner of certification, as the case may be, on or before
the date that any such form expires or becomes obsolete or after the occurrence
of any event requiring a change in the most recent form previously delivered by
it to the Borrowers, certifying in the case of a Form W-8BEN or W-8ECI that such
Lender is entitled to receive payments under this Agreement without deduction or
withholding of any United States federal income taxes (unless in any such case
an event (including without limitation any change in treaty, law or regulation)
has occurred prior to the date on which any such delivery would otherwise be
required which renders such forms inapplicable or the exemption to which such
forms relate unavailable and such Lender notifies the Borrowers and the

under the laws of the jurisdiction of its incorporation or formation, has the
power and authority to own its properties and to carry on its business as now
being and hereafter proposed to be conducted and is duly qualified and
authorized to do business in each jurisdiction in which the character of its
properties or the nature of its business requires such qualification and
authorization, except where the failure to be duly qualified and authorized will

each Subsidiary thereof are organized and qualified to do business as of the
Closing Date are described on Schedule 7.1(a).

shares have been duly authorized and validly issued and are fully paid and
nonassessable. The shareholders of the Subsidiaries of each Borrower and the

        (c)    Authorization of Agreement, Loan Documents and Borrowing.    Each
Borrower and each Subsidiary thereof has the right, power and authority and has
taken all necessary corporate and other action to authorize the execution,
delivery and performance of this Agreement and each of the other Loan Documents
to which it is a party in accordance with their respective terms. This Agreement
and each of the other Loan Documents have been duly executed and delivered by
the duly authorized officers of each Borrower and each of its Subsidiaries party
thereto, and each such document constitutes the legal, valid and binding
obligation of each Borrower or its Subsidiary party thereto, enforceable in
accordance with its terms, except as such enforcement may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar state or federal
debtor relief laws from time to time in effect which affect the enforcement of
creditors' rights in general and the availability of equitable remedies.

        (d)    Compliance of Agreement, Loan Documents and Borrowing with Laws,
Etc.    The execution, delivery and performance by each Borrower and each
Subsidiary thereof of the Loan Documents to which each such Person is a party,
in accordance with their respective terms, the Extensions of Credit hereunder,
the granting of the Liens under the Security Documents and the transactions
contemplated hereby do not and will not, by the passage of time, the giving of
notice or otherwise, (i) require any Governmental Approval or violate any
Applicable Law relating to any Borrower or any Subsidiary thereof, (ii) conflict
with, result in a breach of or constitute a default under (A) the articles of
incorporation, bylaws or other organizational documents of any Borrower or any
Subsidiary thereof or (B) any indenture, agreement or other instrument to which
such Person is a party or by which any of its properties may be bound or any
Governmental Approval relating to such Person which could reasonably be expected
to have a Material Adverse Effect, or (iii) result in or require the creation or
imposition of any Lien upon or with respect to any property now owned or
hereafter acquired by such Person other than Liens arising under the Loan
Documents.

        (e)    Compliance with Law; Governmental Approvals.    Each Borrower and
each Subsidiary thereof (i) has all Governmental Approvals required by any
Applicable Law for it to conduct its business, each of which is in full force
and effect, is final and not subject to review on appeal and is not the subject
of any pending or, to the best of its knowledge, threatened attack by direct or
collateral proceeding, and (ii) is in compliance with each Governmental Approval
applicable to it and in compliance with all other Applicable Laws relating to it
or any of its respective properties, in each case except to the extent that any
such lack of Governmental Approval or failure to comply would not have a
Material Adverse Effect.

        (f)    Tax Returns and Payments.    Each Borrower and each Subsidiary
thereof has duly filed or caused to be filed all federal, state, material local
and other tax returns required by Applicable Law to be filed, and has paid, or
made adequate provision for the payment of, all federal, state, local and other
taxes, assessments and governmental charges or levies upon it and its property,
income, profits and assets which are due and payable. Except as set forth on
Schedule 7.1(f) and except for claims for taxes which are being contested in
good faith and as to which adequate reserves are maintained in accordance with
GAAP, no Governmental Authority has asserted any Lien or other claim against any
Borrower or Subsidiary thereof with respect to unpaid taxes which has not been
discharged or resolved. The charges, accruals and reserves on the books of each
Borrower and each Subsidiary thereof in

39

--------------------------------------------------------------------------------

respect of federal, state, material local and other taxes for all Fiscal Years
and portions thereof since the organization of such Borrower and each Subsidiary
thereof are in the judgment of each such Borrower adequate, and each such
Borrower does not anticipate any additional taxes or assessments for any of such
years.

        (g)    Intellectual Property Matters.    Each Borrower and each
Subsidiary thereof owns or possesses rights to use all franchises, licenses,
copyrights, copyright applications, patents, patent rights or licenses, patent
applications, trademarks, trademark rights, trade names, trade name rights,
copyrights and rights with respect to the foregoing which are required to
conduct its business. No event has occurred which permits, or after notice or
lapse of time or both would permit, the revocation or termination of any such
rights, and no Borrower nor any Subsidiary thereof is liable to any Person for
infringement under Applicable Law with respect to any such rights as a result of
its business operations.

        (h)    Environmental Matters.    In the ordinary course of its business,
each Borrower conducts an ongoing review of the effect of Environmental Laws on
the business, operations and properties of such Borrower and its Subsidiaries,
in the course of which it identifies and evaluates associated liabilities and
costs (including, without limitation, any capital or operating expenditures
required for clean-up or closure of properties presently or previously owned,
any capital or operating expenditures required to achieve or maintain compliance
with environmental protection standards imposed by law or as a condition of any
license, permit or contract, any related constraints on operating activities,
including any periodic or permanent shutdown of any facility or reduction in the
level of or change in the nature of operations conducted at any such facility,
any costs or liabilities in connection with off-site disposal of wastes or
Hazardous Substances, and any actual or potential liabilities to third parties,
including employees, and any related costs and expenses). On the basis of this
review, each Borrower has concluded that such associated liabilities and costs,
including the costs of compliance with Environmental Laws, could not reasonably
be expected to have a Material Adverse Effect.

        (i)    ERISA.

maintains or contributes to, or has any obligation under, any Employee Benefit
Plans other than those identified on Schedule 7.1(i);

with all applicable provisions of ERISA and the regulations and published
interpretations thereunder with respect to all Employee Benefit Plans except for

Multiemployer Plan;

there been any event requiring any disclosure under Section 4041(c)(3)(C) or
4063(a) of ERISA with respect to any Pension Plan;

40

--------------------------------------------------------------------------------

        (iv)  No Borrower nor any ERISA Affiliate has: (A) engaged in a
nonexempt prohibited transaction described in Section 406 of the ERISA or
Section 4975 of the Code, (B) incurred any liability to the PBGC which remains
outstanding other than the payment of premiums and there are no premium payments

engaged principally or as one of its activities in the business of extending
credit for the purpose of "purchasing" or "carrying" any "margin stock" (as each
such term is defined or used in Regulation U of the Board of Governors of the
Federal Reserve System). No part of the proceeds of any of the Loans or Letters
of Credit will be used for purchasing or carrying margin stock or for any
purpose which violates, or which would be inconsistent with, the provisions of
Regulation T, U or X of such Board of Governors.

        (k)    Government Regulation.    No Borrower nor any Subsidiary thereof
is an "investment company" or a company "controlled" by an "investment company"
(as each such term is defined or used in the Investment Company Act of 1940, as

to any Extension of Credit will be, subject to regulation under the Public
Utility Holding Company Act of 1935 or the Interstate Commerce Act, each as
amended, or any other Applicable Law which limits its ability to incur or
consummate the transactions contemplated hereby.

has a stable work force in place and is not, as of the Closing Date, party to
any collective bargaining agreement nor has any labor union been recognized as
the representative of its employees except as set forth on Schedule 7.1(m). No

Subsidiaries, which would have a Material Adverse Effect.

the Closing Date are complete and correct in all material respects and fairly
present the assets, liabilities and financial position of the Borrowers and
their Subsidiaries as at such dates, and the results of the operations and

Subsidiary thereof subsequent to such date which dispositions have been in the
ordinary course of business or as otherwise expressly permitted hereunder.

        (r)    Liens.    None of the properties and assets of any Borrower or
any Subsidiary thereof is subject to any Lien, except Permitted Liens. No
financing statement under the Uniform Commercial Code of any state which names
any Borrower or any Subsidiary thereof or any of their respective trade names or
divisions as debtor and which has not been terminated, has been filed in any

        SECTION 12.2    Remedies.     Upon the occurrence and during the
continuation of an Event of Default, with the consent of the Required Lenders,
the Administrative Agent may, or upon the request of the Required Lenders, the
Administrative Agent shall, by notice to the Borrowers:

        (a)    Acceleration; Termination of Facilities.    Declare the principal
of and interest on the Loans, the Notes and the Reimbursement Obligations at the
time outstanding, and all other amounts owed to the Lenders and to the
Administrative Agent under this Agreement or any of the other Loan Documents
(other than any Hedging Agreement) (including, without limitation, all L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) and all other
Obligations (other than obligations owing under any Hedging Agreement), to be
forthwith due and payable, whereupon the same shall immediately become due and
payable without presentment, demand, protest or other notice of any kind, all of
which are expressly waived, anything in this Agreement or the other Loan
Documents to the contrary notwithstanding, and terminate the Credit Facility and
any right of the Borrowers to request borrowings or Letters of Credit
thereunder; provided, that upon the occurrence of an Event of Default specified
in Section 12.1(j) or (k), the Credit Facility shall be automatically terminated
and all Obligations (other than obligations owing under any Hedging Agreement)
shall automatically become due and payable, without presentment, demand, protest
or other notice of any kind, all of which are hereby expressly waived.

        (b)    Letters of Credit.    With respect to all Letters of Credit with
respect to which presentment for honor shall not have occurred at the time of an
acceleration pursuant to the preceding paragraph, require the Borrowers at such
time to deposit in a cash collateral account opened by the Administrative Agent
an amount equal to the aggregate then undrawn and unexpired amount of such
Letters of Credit. Amounts held in such cash collateral account shall be applied

privilege shall operate as a waiver thereof, nor shall any single or partial
exercise of any such right, power or privilege preclude other or further
exercise thereof or the exercise of any other right, power or privilege or shall
be construed to be a waiver of any Event of Default. No course of dealing
between the Borrowers, the Administrative Agent and the Lenders or their
respective agents or employees shall be effective to change, modify or discharge

THE ADMINISTRATIVE AGENT AND COLLATERAL AGENT

        SECTION 13.1    Appointment.     Each of the Lenders hereby irrevocably
designates and appoints Wachovia as Administrative Agent and as Collateral Agent
of such Lender, in each case, under this Agreement and the other Loan Documents
for the term hereof and each such Lender irrevocably authorizes each of Wachovia
as Administrative Agent and as Collateral Agent for such Lender, to take such
action on its behalf under the provisions of this Agreement and the other Loan
Documents and to exercise such powers and perform such duties as are expressly
delegated to such Agent by the terms of this Agreement and such other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement or
such other Loan Documents, neither Agent shall have any duties or
responsibilities, except those expressly set forth herein and therein, or any
fiduciary relationship with any Lender, and no implied covenants, functions,
responsibilities, duties, obligations or liabilities shall be read into this
Agreement or the other Loan Documents or otherwise exist against any Agent. Any
reference to the Agent in this Article XIII shall be deemed to refer to the
Administrative Agent or Collateral Agent, as applicable, solely in its capacity
as Administrative Agent or Collateral Agent, as applicable, and not in its
capacity as a Lender.

        SECTION 13.2    Delegation of Duties.     The Agents may execute any of
their respective duties under this Agreement and the other Loan Documents by or
through agents or attorneys-in-fact and shall be entitled to advice of counsel

such Agent with reasonable care.

        SECTION 13.3    Exculpatory Provisions.     Neither Agent nor any of
such Agent's officers, directors, employees, agents, attorneys-in-fact,
Subsidiaries or Affiliates shall be (a) liable for any action lawfully taken or

Agreement or the other Loan Documents (except for actions occasioned solely by
its or such Person's own gross negligence or willful misconduct), or (b)
responsible in any manner to any of the Lenders for any recitals, statements,
representations or warranties made by any Borrower or any Subsidiary thereof or
any officer thereof contained in this Agreement or the other Loan Documents or
in any certificate, report, statement or other document referred to or provided
for in, or received by such Agent under or in connection with, this Agreement or
the other Loan Documents or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement or the other Loan Documents or
for any failure of any Borrower or any Subsidiary thereof to perform its
obligations hereunder or thereunder. No Agent shall be under any obligation to
any Lender to ascertain or to inquire as to the observance or performance of any
of the agreements contained in, or conditions of, this Agreement, or to inspect
the properties, books or records of the Borrowers or any of their Subsidiaries.

        SECTION 13.4    Reliance by the Agents.     The Agents shall be entitled
to rely, and shall be fully protected in relying, upon any note, writing,
resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype message, statement, order or other
document or conversation believed by such Agent to be genuine and correct and to
have been signed, sent or made by the proper Person or Persons and upon advice
and statements of legal counsel (including, without limitation, counsel to the
Borrowers), independent accountants and other experts selected by such Agent.
The Agents may deem and treat the payee of any Note as the owner thereof for all
purposes unless such Note shall have been transferred in accordance with Section
14.10 hereof. The Agents shall be fully justified in failing or refusing to take
any action under this Agreement and the other Loan Documents unless such Agent
shall first receive such advice or concurrence of the Required Lenders (or, when
expressly required hereby or by the relevant other Loan Document, all the
Lenders) as it deems appropriate or it shall first be indemnified to its
satisfaction by the Lenders against any and all liability and expense which may
be incurred by it by reason of taking or continuing to take any such

63

--------------------------------------------------------------------------------

action except for its own gross negligence or willful misconduct. The Agents
shall in all cases be fully protected in acting, or in refraining from acting,
under this Agreement and the Notes in accordance with a request of the Required
Lenders (or, when expressly required hereby, all the Lenders), and such request
and any action taken or failure to act pursuant thereto shall be binding upon
all the Lenders and all future holders of the Notes.

        SECTION 13.5    Notice of Default.     No Agent shall be deemed to have
knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless it has received notice from a Lender or the Borrowers referring
to this Agreement, describing such Default or Event of Default and stating that
such notice is a "notice of default". In the event that any Agent receives such
a notice, it shall promptly give notice thereof to the other Agent and to the
Lenders. The Agents shall take such action with respect to such Default or Event
of Default as shall be reasonably directed by the Required Lenders; provided
that unless and until such Agent shall have received such directions, such Agent
may (but shall not be obligated to) take such action, or refrain from taking
such action, with respect to such Default or Event of Default as it shall deem
advisable in the best interests of the Lenders, except to the extent that other
provisions of this Agreement expressly require that any such action be taken or
not be taken only with the consent and authorization or the request of the
Lenders or Required Lenders, as applicable.

        SECTION 13.6    Non-Reliance on the Agents and Other Lenders.     Each
Lender expressly acknowledges that neither Agent nor any of such Agent's
officers, directors, employees, agents, attorneys-in-fact, Subsidiaries or
Affiliates has made any representations or warranties to it and that no act by
any Agent hereinafter taken, including any review of the affairs of the
Borrowers or any of their Subsidiaries, shall be deemed to constitute any
representation or warranty by such Agent to any Lender. Each Lender represents
to each Agent that it has, independently and without reliance upon any Agent or
any other Lender, and based on such documents and information as it has deemed
appropriate, made its own appraisal of and investigation into the business,
operations, property, financial and other condition and creditworthiness of the
Borrowers and their Subsidiaries and made its own decision to make its Loans and
issue or participate in Letter of Credit hereunder and enter into this
Agreement. Each Lender also represents that it will, independently and without
reliance upon any Agent or any other Lender, and based on such documents and
information as it shall deem appropriate at the time, continue to make its own
credit analysis, appraisals and decisions in taking or not taking action under
this Agreement and the other Loan Documents, and to make such investigation as
it deems necessary to inform itself as to the business, operations, property,
financial and other condition and creditworthiness of the Borrowers and their
Subsidiaries. Except for notices, reports and other documents expressly required
to be furnished to the Lenders by an Agent hereunder or by the other Loan
Documents, no Agent shall have any duty or responsibility to provide any Lender
with any credit or other information concerning the business, operations,
property, financial and other condition or creditworthiness of the Borrowers or
any of their Subsidiaries which may come into the possession of any Agent or any
of its respective officers, directors, employees, agents, attorneys-in-fact,
Subsidiaries or Affiliates.

        SECTION 13.7    Indemnification.     The Lenders agree to indemnify each
Issuing Lender and each of the Administrative Agent, Collateral Agent,
Documentation Agent and Syndication Agent in its respective capacity as such and
(to the extent not reimbursed by the Borrowers and without limiting the
obligation of the Borrowers to do so), ratably according to the respective
amounts of their Revolving Credit Commitment Percentage, Term A Loan Percentage
and/or Term B Loan Percentage, as applicable, from and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever which may at any time
(including, without limitation, at any time following the payment of the Notes
or any Reimbursement Obligation) be imposed on, incurred by or asserted against
any Agent in any way relating to or arising out of this Agreement or the other
Loan Documents, or any documents contemplated by or referred to

64

--------------------------------------------------------------------------------

herein or therein or the transactions contemplated hereby or thereby or any
action taken or omitted by any Agent under or in connection with any of the
foregoing; provided that no Lender shall be liable for the payment of any
portion of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements resulting solely from such
Agent's bad faith, gross negligence or willful misconduct. The agreements in
this Section 13.7 shall survive the payment of the Notes, any Reimbursement
Obligation and all other amounts payable hereunder and the termination of this
Agreement.

        SECTION 13.8    The Agents in Their Individual Capacity.     Each Agent
and its respective Subsidiaries and Affiliates may make loans to, accept
deposits from and generally engage in any kind of business with the Borrowers as
though such Agent were not an Agent hereunder. With respect to any Loans made or
renewed by it and any Note issued to it and with respect to any Letter of Credit
issued by it or participated in by it, such Agent shall have the same rights and
powers under this Agreement and the other Loan Documents as any Lender and may
exercise the same as though it were not an Agent, and the terms "Lender" and
"Lenders" shall include the Agent in its individual capacity, if applicable.

        SECTION 13.9    Resignation of the Agents; Successor Agents.     Subject
to the appointment and acceptance of a successor as provided below, any Agent
may resign at any time by giving notice thereof to the Lenders and the
Borrowers. Upon any such resignation, the Required Lenders shall have the right
to appoint a successor Agent, which successor shall have minimum capital and
surplus of at least $500,000,000. If no successor Agent shall have been so
appointed by the Required Lenders and shall have accepted such appointment
within thirty (30) days after such Agent's giving of notice of resignation, then
such Agent may, on behalf of the Lenders, appoint a successor Agent, which
successor shall have minimum capital and surplus of at least $500,000,000. Upon
the acceptance of any appointment as Agent hereunder by a successor Agent, such
successor Agent shall thereupon succeed to and become vested with all rights,
powers, privileges and duties of the retiring Agent, and the retiring Agent
shall be discharged from its duties and obligations hereunder. After any
retiring Agent's resignation hereunder as Agent, the provisions of this Section
13.9 shall continue in effect for its benefit in respect of any actions taken or
omitted to be taken by it while it was acting as Agent.

        SECTION 13.10    Documentation Agent and Syndication Agent.     The
Documentation Agent and the Syndication Agent, each in its respective capacity
as Documentation Agent or Syndication Agent, shall have no duties or
responsibilities under this Agreement or any other Loan Document.

extent of such excess payment.

73

indemnity under this Section 14.19 or under Applicable Law shall in all events
and all respects be subject and subordinate to the rights of the Administrative
Agent and the Lenders under this Agreement and subject to the prior full, final
and indefeasible payment to the Administrative Agent and the Lenders of all
Obligations and no such right may be exercised until all of such Obligations
have been fully, finally and indefeasibly paid and such payments are in no event

Effect of Covenants.     

        (a)  In the event there is a conflict or inconsistency between this
Agreement and any other Loan Document, the terms of this Agreement shall
control; provided, that any provision of the Security Documents which imposes
additional burdens on any Borrower or any Subsidiary thereof or further
restricts the rights of any Borrower or any Subsidiary thereof or gives the
Agents or Lenders additional rights shall not be deemed to be in conflict or
inconsistent with this Agreement and shall be given full force and effect.

        (b)  The Borrowers expressly acknowledge and agree that each covenant
contained in Articles IX, X, or XI hereof shall be given independent effect.
Accordingly, the Borrowers shall not engage in any transaction or other act
otherwise permitted under any covenant contained in Articles IX, X, or XI if,
