                                   ARTICLE II

                                    THE LOANS

              Section 2.01. COMMITMENTS.  Subject to the terms and conditions
set forth herein, each Lender agrees to make Loans to the Borrower at any time
and from time to time during each Availability Period in an aggregate principal
amount not exceeding its Commitment at the time.  Amounts repaid in respect of
Loans thereon may not be reborrowed.

              Section 2.02. LOANS AND BORROWINGS.

              (a)    Each Loan shall be made as part of a Borrowing consisting
of Loans of the same Class and Type made by the Lenders ratably in accordance
with their respective Commitments. The failure of any Lender to make any Loan
required to be made by it shall not relieve any other Lender of its obligations
hereunder; PROVIDED that the Commitments of the Lenders are several and no
Lender shall be responsible for any other Lender's failure to make Loans as
required.

              (b)    Subject to Section 2.12, each Borrowing shall be comprised
entirely of LIBOR Loans or ABR Loans as the Borrower may request in accordance
herewith.  Each Lender at its option may make any LIBOR Loan by causing any
domestic or foreign branch or Affiliate of such Lender to make such Loan;
PROVIDED that any exercise of such option shall not affect the obligation of the
Borrower to repay such Loan thereon in accordance with the terms of this
Agreement.

              (c)    At the commencement of each Interest Period for any LIBOR
Borrowing, such Borrowing shall be in an aggregate amount that is an integral
multiple of $100,000 and not less than $1,000,000.  Borrowings of more than one
Type and Class may be outstanding at the same time; PROVIDED that there shall
not be more than six LIBOR Borrowings with respect to Tranche 1 Loans and six
LIBOR Borrowings with respect to Tranche 2 Loans outstanding at the same time.


                                       22

<PAGE>

              (d)    Notwithstanding any other provision of this Agreement, the
Borrower shall not be entitled to request, or to elect to convert or continue,
any Borrowing as a LIBOR Borrowing if the Interest Period requested with respect
thereto would end after the Maturity Date for the Loans included in such
Borrowing.

              Section 2.03. REQUESTS FOR BORROWINGS.  To request a Borrowing,
the Borrower shall notify the Administrative Agent of such request by telephone
(a) in the case of a LIBOR Borrowing, not later than 11:00 a.m., New York City
time, three Business Days before the date of the proposed Borrowing or (b) in
the case of an ABR Borrowing, not later than 11:00 a.m., New York City time, one
Business Day before the date of the proposed Borrowing; PROVIDED that (i) the
Borrower may make only one request for a Borrowing in any single calendar month
(it being understood that all Borrowings made by the Borrower on the same date
shall be treated as a single request for a Borrowing for purposes of this
limitation) and (ii) if any Lucent Lender has a Commitment at the time of such
Borrowing and any portion of the proceeds of such Borrowing to be funded by such
Lucent Lender would be required to be funded by such Lucent Lender other than as
a credit against amounts owing to Lucent or an Affiliate of Lucent as provided
in Section 2.04, then the applicable Borrowing Request shall be made not later
than five Business Days before the date of the proposed Borrowing (in the case
of a LIBOR Borrowing) or three Business Days before the date of the proposed
Borrowing (in the case of an ABR Borrowing).  Each such telephonic Borrowing
Request shall be irrevocable and shall be confirmed promptly by hand delivery or
telecopy to the Administrative Agent of a written Borrowing Request in a form
approved by the Administrative Agent and signed by the Borrower.  Each such
telephonic and written Borrowing Request shall specify the following information
in compliance with Section 2.02:

              (i)    the aggregate amount of such Borrowing and a reasonably
       detailed description of the use of the proceeds therefrom (and each
       written Borrowing Request shall attach copies of all invoices to be paid
       with such proceeds);

              (ii    the date of such Borrowing, which shall be a Business Day;

              (iii)  whether such Borrowing is to be a LIBOR Borrowing or an ABR
       Borrowing;

              (iv)   in the case of a LIBOR Borrowing, the initial Interest
       Period to be applicable thereto, which shall be a period contemplated by
       the definition of the term "Interest Period"; and

              (v)    the location and number of the account or accounts to which
       funds (if any) are to be disbursed, which shall comply with the
       requirements of Section 2.04.

If no election as to the Type of Borrowing is specified, then the requested
Borrowing shall be an ABR Borrowing.  If no Interest Period is specified with
respect to any requested LIBOR Borrowing, then the Borrower shall be deemed to
have selected an Interest Period of one month's duration.  Promptly following
receipt of a Borrowing Request in accordance with this Section, the
Administrative Agent shall advise each Lender of the details thereof and of the
amount of such Lender's Loan to be made as part of the requested Borrowing.

              Section 2.04. FUNDING OF BORROWINGS.

              (a)    Each Lender shall make each Loan to be made by it hereunder
on the proposed date thereof by wire transfer of immediately available funds by
12:00 noon, New York City time, to the account of the Administrative Agent most
recently designated by it for such purpose by notice to the Lenders.  The
Administrative Agent will make such Loans available to the Borrower by promptly
crediting the amounts so received, in like funds, to an account of the Borrower
designated by the Borrower in the applicable Borrowing Request.  Notwithstanding
the foregoing, if the proceeds of any Borrowing are to be used to make any
payment to or for the account of Lucent or any Affiliate thereof (i) if any
Lucent Lender has a Commitment, then such Lucent Lender may make its Loan by
crediting the amount thereof against the payment obligations to Lucent or any
such Affiliate and shall be deemed to have made a Loan in the amount of such
credit and (ii) the Administrative Agent will make the Loans of the other
Lenders available to the Borrower by promptly crediting the amounts so received
from such other Lenders, in immediately available funds, to an account of Lucent
maintained with the Administrative Agent for such purpose, to the extent of the
proceeds of such Loans designated to be used to make payments to Lucent or any
of its Affiliates (after giving effect to any credits pursuant to clause (i)
above) and the balance, if any, of such proceeds shall be made available to the
Borrower as provided in the preceding sentence.

              (b)    Unless the Administrative Agent shall have received notice
from a Lender prior to the proposed date of any Borrowing that such Lender will
not make available to the Administrative Agent such Lender's share of such
Borrowing, the Administrative Agent may assume that such Lender has made such
share available on such date in accordance with paragraph (a) of this Section
and may, in reliance upon such assumption, make available to the Borrower a
corresponding amount.  In such event, if a Lender has not in fact made its share
of the applicable Borrowing available to the Administrative Agent, then the
applicable Lender and the Borrower severally agree to pay to the Administrative
Agent forthwith on demand such corresponding amount with interest thereon, for
each day from and including the date such amount is made available to the
Borrower to but excluding the date of payment to the Administrative Agent, at
(i) in the case of such Lender, the greater of the Federal Funds Effective Rate
and a rate determined by the Administrative Agent in accordance with banking
industry rules on interbank compensation or (ii) in the case of the Borrower,
the interest rate applicable to ABR Loans of the same Class.  If such Lender
pays such amount to the Administrative Agent, then such amount shall constitute
such Lender's Loan included in such Borrowing.  Nothing in this Section 2.04(b)
shall prejudice the Borrower's rights against any such defaulting Lender.

              Section 2.05. INTEREST ELECTIONS.

              (a)    Each Borrowing initially shall be of the Type specified in
the applicable Borrowing Request and, in the case of a LIBOR Borrowing, shall
have an initial Interest Period as specified in such Borrowing Request. 
Thereafter, the Borrower may elect to convert such Borrowing to a different Type
or to continue such Borrowing and, in the case of a LIBOR Borrowing, may elect
Interest Periods therefor, all as provided in this Section.  The Borrower may
elect different options with respect to different portions of the affected
Borrowing, in which case each such portion shall be allocated ratably among the
Lenders holding the Loans 


                                       24

<PAGE>

comprising such Borrowing, and the Loans comprising each such portion shall 
be considered a separate Borrowing.

              (b)    To make an election pursuant to this Section, the Borrower
shall notify the Administrative Agent of such election by telephone by the time
that a Borrowing Request would be required under Section 2.03 if the Borrower
were requesting a Borrowing of the Type resulting from such election to be made
on the effective date of such election.  Each such telephonic Interest Election
Request shall be irrevocable and shall be confirmed promptly by hand delivery or
telecopy to the Administrative Agent of a written Interest Election Request in a
form approved by the Administrative Agent and signed by the Borrower.

              (c)    Each telephonic and written Interest Election Request shall
specify the following information in compliance with Section 2.02 and paragraph
(f) of this Section:

              (i)    the Borrowing to which such Interest Election Request
       applies and, if different options are being elected with respect to
       different portions thereof, the portions thereof to be allocated to each
       resulting Borrowing (in which case the information to be specified
       pursuant to clauses (iii) and (iv) below shall be specified for each
       resulting Borrowing);

              (ii)   the effective date of the election made pursuant to such
       Interest Election Request, which shall be a Business Day;

              (iii)  whether the resulting Borrowing is to be a LIBOR Borrowing
       or an ABR Borrowing; and

              (iv)   if the resulting Borrowing is a LIBOR Borrowing, the
       Interest Period to be applicable thereto after giving effect to such
       election, which shall be a period contemplated by the definition of the
       term "Interest Period."

If any such Interest Election Request requests a LIBOR Borrowing but does not
specify an Interest Period, then the Borrower shall be deemed to have selected
an Interest Period of one month's duration.

              (d)    Promptly following receipt of an Interest Election Request,
the Administrative Agent shall advise each Lender of the details thereof and of
such Lender's portion of each resulting Borrowing.

              (e)    If the Borrower fails to deliver a timely Interest Election
Request with respect to a LIBOR Borrowing prior to the end of the Interest
Period applicable thereto, then, unless such Borrowing is repaid as provided
herein, at the end of such Interest Period such Borrowing shall be converted to
an ABR Borrowing.  Notwithstanding any contrary provision hereof, if an Event of
Default has occurred and is continuing, then, so long as an Event of Default is
continuing (i) no outstanding Borrowing may be converted to or continued as a
LIBOR Borrowing at the end of the then current Interest Period and (ii) unless
repaid, each LIBOR Borrowing shall be converted to an ABR Borrowing at the end
of the Interest Period applicable thereto.


                                       25

<PAGE>

              (f)    A Borrowing of any Class may not be converted to or
continued as a LIBOR Borrowing if after giving effect thereto (i) the Interest
Period therefor would commence before and end after a date on which any
principal of the Loans of such Class is scheduled to be repaid and (ii) the sum
of the aggregate principal amount of outstanding LIBOR Borrowings of such Class
with Interest Periods ending on or prior to such scheduled repayment date plus
the aggregate principal amount of outstanding ABR Borrowings of such Class would
be less than the aggregate principal amount of Loans of such Class required to
be repaid on such scheduled repayment date.

              Section 2.06. TERMINATION AND REDUCTION OF COMMITMENTS.

              (a)    Unless previously terminated, the Commitments with respect
to Tranche 1 Loans shall terminate on the Tranche 1 Availability Termination
Date and the Commitments with respect to Tranche 2 Loans shall terminate on the
Tranche 2 Availability Termination Date.

              (b)    On the date of each Loan made by any Lender such Lender's
Commitment shall be reduced by an amount equal to such Loan.

              (c)    If a prepayment would be required pursuant to paragraph (b)
or (c) of Section 2.09, all Commitments then in effect shall be reduced ratably
by an aggregate amount equal to the excess, if any, of the amount of the
required prepayment over the aggregate principal amount of Loans outstanding
immediately prior to giving effect to such prepayment.

              (d)    The Borrower may at any time terminate, or from time to
time reduce, the Commitments; PROVIDED that each reduction of the Commitments
pursuant to this paragraph (d) shall be in an amount that is an integral
multiple of $1,000,000 and not less than $1,000,000.

              (e)    The Borrower shall notify the Administrative Agent of any
election to terminate or reduce the Commitments under paragraph (d) of this
Section at least one Business Day prior to the effective date of such
termination or reduction, specifying such election and the effective date
thereof.  Promptly following receipt of any such notice, the Administrative
Agent shall advise the Lenders of the contents thereof.  Each notice delivered
by the Borrower pursuant to this Section shall be irrevocable.  Any termination
or reduction of the Commitments shall be permanent.  Each reduction of the
Commitments pursuant to paragraph (d) of this Section shall be made ratably
among the Lenders in accordance with their respective Commitments; PROVIDED that
the Borrower may, in its discretion, reduce the Commitments of Lucent Lenders
pursuant to such paragraph (d) without reducing the Commitments of other
Lenders.

              Section 2.07. REPAYMENT OF LOANS; EVIDENCE OF DEBT.

              (a)    The Borrower hereby unconditionally promises to pay to the
Administrative Agent for the account of each Lender the then unpaid principal
amount of each Loan of such Lender as provided in Section 2.08.

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


                                       26

<PAGE>

              (c)    The Administrative Agent shall maintain accounts in which
it shall record (i) the amount of each Loan made hereunder, the Class and Type
thereof and the Interest Period applicable thereto, (ii) the amount of any
principal or interest due and payable or to become due and payable from the
Borrower to each Lender hereunder and (iii) the amount of any sum received by
the Administrative Agent hereunder for the account of the Lenders and each
Lender's share thereof.

              (d)    The entries made in the accounts maintained pursuant to
paragraph (b) or (c) of this Section shall be PRIMA FACIE evidence of the
existence and amounts of the obligations recorded therein; PROVIDED that the
failure of any Lender or the Administrative Agent to maintain such accounts or
any error therein shall not in any manner affect the obligation of the Borrower
to repay the Loans in accordance with the terms of this Agreement.

              (e)    Any Lender may request that Loans of any Class made by it
be evidenced by a promissory note.  In such event, the Borrower shall prepare,
execute and deliver to such Lender such a promissory note payable to the order
of such Lender (or, if requested by such Lender, to such Lender and its
registered assigns) and in a form approved by the Administrative Agent. 
Thereafter, the Loans evidenced by such promissory note and interest thereon
shall at all times (including after assignment pursuant to Section 9.04) be
represented by one or more promissory notes in such form payable to the order of
the payee named therein (or, if such promissory note is a registered note, to
such payee and its registered assigns).

              Section 2.08. AMORTIZATION OF LOANS.

              (a)    Subject to adjustment pursuant to paragraph (c) of this 
Section, the Borrower shall repay Borrowings on each of the first four 
Payment Dates in an aggregate amount equal to [  *  ] of the sum of all Loans 
made or deemed made hereunder (including amounts previously repaid or 
prepaid), on each of the second four Payment Dates in an aggregate amount 
equal to [  *  ] of the sum of all Loans made or deemed made hereunder 
(including amounts previously repaid or prepaid) and on each of the remaining 
Payment Dates in an aggregate amount equal to [  *  ] of the sum of all Loans 
made or deemed made hereunder (including amounts previously repaid or 
prepaid).

              (b)    To the extent not previously paid, all Loans of each Class
shall be due and payable on the Maturity Date with respect to Loans of such
Class.

              (c)    Any prepayment of a Borrowing of any Class shall be applied
to reduce ratably the subsequent scheduled repayments of the Borrowings of such
Class to be made pursuant to this Section; PROVIDED that any prepayment of a
Borrowing of any Class that is made pursuant to Section 2.09(a) shall be applied
to reduce the subsequent scheduled repayments of the Borrowings of such Class to
be made pursuant to this Section in reverse chronological order or, at the
election of any Lender with respect to any portion of such prepayment payable to
such Lender, to reduce ratably the subsequent scheduled repayments of the
Borrowings of such Class to be made pursuant to this Section.

              (d)    Prior to any repayment of any Borrowings of any Class
hereunder, the Borrower shall select the Borrowing or Borrowings of the
applicable Class to be repaid and shall


                                    * INDICATES CONFIDENTIAL TREATMENT REQUESTED

                                       27

<PAGE>

notify the Administrative Agent by telephone (confirmed by telecopy) of such
selection not later than 11:00 a.m., New York City time, three Business Days
before the scheduled date of such repayment; PROVIDED that each repayment of
Borrowings of any Class shall be applied to repay any outstanding ABR Borrowings
of such Class before any other Borrowings of such Class. If the Borrower fails
to make a timely selection of the Borrowing or Borrowings to be repaid, such
repayment shall be applied, first, to repay any outstanding ABR Borrowings of
the applicable Class and, second, to other Borrowings of the applicable Class in
the order of the remaining duration of their respective Interest Periods (the
Borrowing with the shortest remaining Interest Period to be repaid first). Each
repayment of a Borrowing shall be applied, ratably to the Loans included in the
repaid Borrowing. Repayments of Borrowings shall be accompanied by the payment
of accrued interest on the amount thereof.

              Section 2.09. PREPAYMENT OF LOANS.

              (a)    The Borrower shall have the right at any time and from time
to time to prepay any Borrowing in whole or in part subject to the requirements
of this Section without penalty or premium (except as provided in Section 2.14
or 2.15).

              (b)    In the event and on each occasion that any Net Proceeds are
received by or on behalf of the Borrower or any Subsidiary in respect of any
Prepayment Event, the Borrower shall, within six Business Days after such Net
Proceeds are received, prepay Borrowings in an aggregate amount equal to such
Net Proceeds.

              (c)    Following the end of each fiscal year of the Borrower, 
commencing with the fiscal year ending on or after the Effective Date, for 
which there is any Excess Cash Flow, the Borrower shall prepay Borrowings in 
an aggregate amount equal to [  *  ].  Each prepayment pursuant to this 
paragraph shall be made on or before the date on which financial statements 
are delivered pursuant to Section 5.01 with respect to the fiscal year for 
which Excess Cash Flow is being calculated (and in any event within 90 days 
after the end of such fiscal year).

              (d)    Prior to any optional or mandatory prepayment of Borrowings
hereunder, the Borrower shall select the Borrowing or Borrowings to be prepaid
and shall specify such selection in the notice of such prepayment pursuant to
paragraph (e) of this Section; PROVIDED that each prepayment of Borrowings of
any Class shall be applied to prepay ABR Borrowings of such Class before any
other Borrowings of such Class.  If optional or mandatory prepayment of
Borrowings made at a time when Borrowings of more than one Class are
outstanding, the Borrower shall select Borrowings to be prepaid so that the
aggregate amount of such prepayment is allocated among the Classes pro rata
based on the aggregate principal amount of outstanding Borrowings of each such
Class.

              (e)    The Borrower shall notify the Administrative Agent by
telephone (confirmed by telecopy) of any prepayment hereunder (i) in the case of
prepayment of a LIBOR Borrowing, not later than 1:00 p.m., New York City time,
three Business Days before the date of prepayment or (ii) in the case of
prepayment of an ABR Borrowing, not later than 11:00 a.m., New York City time,
one Business Day before the date of prepayment.  Each such notice shall be
irrevocable and shall specify the prepayment date, the principal amount of each
Borrowing or


                                    * INDICATES CONFIDENTIAL TREATMENT REQUESTED

                                       28

<PAGE>

portion thereof to be prepaid and, in the case of a mandatory prepayment, a
reasonably detailed calculation of the amount of such prepayment. Promptly
following receipt of any such notice, the Administrative Agent shall advise the
Lenders of the contents thereof. Each partial prepayment of any Borrowing shall
be in an amount that is an integral multiple of $100,000 and not less than
$1,000,000, except as necessary to apply fully the required amount of a
mandatory prepayment. Each prepayment of a Borrowing shall be applied ratably to
the Loans included in the prepaid Borrowing. Prepayments of Borrowings shall be
accompanied by the payment of accrued interest on the amount prepaid.

              Section 2.10. FEES.

              (a)    The Borrower agrees to pay to the Administrative Agent 
for the account of each Lender (i) a commitment fee, which shall accrue (at 
the rate per annum separately agreed) on the [  *  ] of such Lender during 
the period from and including the Effective Date to but excluding the date on 
which the Tranche 1 Commitments terminate and (ii) a commitment fee, which 
shall accrue (at a rate per annum separately agreed) on the [  *  ] of such 
Lender during the period from and including the [  *  ] to but excluding the 
date on which the [  *  ] terminate.  Accrued commitment fees shall be 
payable in arrears on each Interest Payment Date and, in the case of 
commitment fees in respect of [  *  ], on the date on which the [  *  ]

the date on which the [  *  ] terminate, commencing on the first such date to 
occur after the Effective Date.  All commitment fees shall be computed on the 
basis of a year of 360 days and shall be payable for the actual number of 
days elapsed (including the first day but excluding the last day).

              (b)    The Borrower agrees to pay to Lucent, for its own account,
fees in the [  *  ].

              (c)    The Borrower agrees to pay to the Administrative Agent (if

              (c)    Notwithstanding the foregoing if any principal of or 
interest on any Loan or any fee or other amount payable by the Borrower 
hereunder is not paid when due, whether at stated maturity, upon acceleration 
or otherwise, such overdue amount shall bear interest, after as well as 
before judgment, at a rate per annum equal to [  *  ] plus the rate 
applicable to ABR Loans as provided in paragraph (a) of this Section.

              (d)    All accrued interest on each Loan shall be payable in
arrears on each Interest Payment Date for such Loan; PROVIDED that (i) interest
accrued pursuant to paragraph (c) of this Section shall be payable [  *  ],
(ii) in the event of any repayment or prepayment of any Loan, accrued interest
on the principal amount of such Loan repaid or prepaid shall be payable on the
date of such repayment or prepayment, or (iii) in the event of any conversion of
any Loan prior to the end of the current Interest Period therefor, accrued
interest on such Loan shall be payable on the effective date of such conversion.

              (e)    All interest hereunder shall be computed on the basis of a
year of 360 days, except that interest computed by reference to the Alternate
Base Rate at times when the Alternate Base Rate is based on the Prime Rate shall
be computed on the basis of a year of 365 days (or 366 days in a leap year), and
in each case shall be payable for the actual number of days elapsed (including
the first day but excluding the last day).  The applicable Alternate Base Rate
or Adjusted LIBO Rate shall be determined in accordance with this Agreement by
the Administrative Agent, and such determination shall be conclusive absent
manifest error.

              Section 2.12. ALTERNATE RATE OF INTEREST.  If prior to the
commencement of any Interest Period for a LIBOR Borrowing:

              (a)    the Administrative Agent determines (which determination
shall be conclusive absent manifest error) that adequate and reasonable means do
not exist for ascertaining the Adjusted LIBO Rate for such Interest Period; or

              (b)    the Administrative Agent is advised by a majority in
interest of the Lenders participating in such Borrowing that the Adjusted LIBO
Rate for such Interest Period will not adequately and fairly reflect the cost to
such Lenders of making or maintaining their Loans included in such Borrowing for
such Interest Period;

then the Administrative Agent shall give notice thereof to the Borrower and the
Lenders by telephone or telecopy as promptly as practicable thereafter and,
until the Administrative Agent notifies the Borrower and the Lenders that the
circumstances giving rise to such notice no longer exist, (i) any Interest
Election Request that requests the conversion of any Borrowing to, or
continuation of any Borrowing as, a LIBOR Borrowing shall be ineffective and
(ii) if any Borrowing Request requests a LIBOR Borrowing, such Borrowing shall
be made as an ABR Borrowing.

              Section 2.13. INCREASED COSTS.

              (a)    If any Change in Law shall:

              (i)    impose, modify or deem applicable any reserve, special
       deposit or similar requirement against assets of, deposits with or for
       the account of, or credit

       extended by, any Lender (except any such reserve requirement reflected 
       in the Adjusted LIBO Rate); or

              (ii)   impose on any Lender or the London interbank market any
       other condition affecting this Agreement or LIBOR Loans made by such
       Lender;

and the result of any of the foregoing shall be to increase the cost to such
Lender of making or maintaining any LIBOR Loan (or of maintaining its obligation
to make any such Loan) or to reduce the amount of any sum received or receivable
by such Lender hereunder (whether of principal, interest or otherwise), then the
Borrower will pay to such Lender such additional amount or amounts as will
compensate such Lender for such additional costs incurred or reduction suffered.

              (b)    If any Lender determines that any Change in Law regarding
capital requirements has or would have the effect of reducing the rate of return
on such Lender's capital or on the capital of such Lender's holding company, if
any, as a consequence of this Agreement or the Loans made by such Lender to a
level below that which such Lender or such Lender's holding company could have
achieved but for such Change in Law (taking into consideration such Lender's
policies and the policies of such Lender's holding company with respect to
capital adequacy), then from time to time the Borrower will pay to such Lender
such additional amount or amounts as will compensate such Lender or such
Lender's holding company for any such reduction suffered.

              (c)    A certificate of a Lender setting forth the amount or
amounts necessary to compensate such Lender or its holding company, as the case
may be, as specified in paragraph (a) or (b) of this Section and the basis
therefor shall be delivered to the Borrower by the applicable Lender (with a
copy to the Administrative Agent) and shall be conclusive absent manifest error
The Borrower shall pay such Lender the amount shown as due on any such
certificate within 30 days after receipt thereof.

              (d)    Failure or delay on the part of any Lender to demand
compensation pursuant to this Section shall not constitute a waiver of such
Lender's right to demand such compensation; PROVIDED that the Borrower shall not
be required to compensate a Lender pursuant to this Section for any increased
costs or reductions incurred more than 270 days prior to the date that such
Lender notifies the Borrower of the Change in Law giving rise to such increased
costs or reductions and of such Lender's intention to claim compensation
therefor; PROVIDED FURTHER that, if the Change in Law giving rise to such
increased costs or reductions is retroactive, then the 270-day period referred
to above shall be extended to include the period of retroactive effect thereof.

              Section 2.14. BREAK FUNDING PAYMENTS; PREPAYMENT FEES.  In the
event of (i) the payment of any principal of any LIBOR Loan other than on the
last day of an Interest Period applicable thereto (including as a result of an
Event of Default), (ii) the conversion of any LIBOR Loan other than on the last
day of the Interest Period applicable thereto, (iii) the failure to borrow,
convert, continue or prepay any Loan on the date specified in any notice
delivered pursuant hereto, or (iv) the assignment of any LIBOR Loan other than
on the last day of the Interest Period applicable thereto as a result of a
request by the Borrower pursuant to Section


                                       31

<PAGE>

2.17, then, in any such event, the Borrower shall compensate each Lender for the
loss, cost and expense attributable to such event. In the case of a LIBOR Loan,
such loss, cost or expense to any Lender shall be deemed to include an amount
determined by such Lender to be the excess, if any, of (i) the amount of
interest which would have accrued on the principal amount of such Loan had such
event not occurred, at the Adjusted LIBO Rate that would have been applicable to
such Loan, for the period from the date of such event to the last day of the
then current Interest Period therefor (or, in the case of a failure to borrow,
convert or continue, for the period that would have been the Interest Period for
such Loan), over (ii) the amount of interest which would accrue on such
principal amount for such period at the interest rate which such Lender would
bid were it to bid, at the commencement of such period, for dollar deposits of a
comparable amount and period from other banks in the eurodollar market. A
certificate of any Lender setting forth any amount or amounts that such Lender
is entitled to receive pursuant to this paragraph shall be delivered to the
Borrower and shall be conclusive absent manifest error. The Borrower shall pay
such Lender the amount shown as due on any such certificate within 10 days after
receipt thereof.

              Section 2.15. TAXES.

              (a)    Any and all payments by or on account of any obligation of
the Borrower hereunder or under any other Loan Document shall be made free and
clear of and without deduction for any Indemnified Taxes or Other Taxes;
PROVIDED that if the Borrower shall be required to deduct any Indemnified Taxes
or Other Taxes from such payments, then (i) the sum payable shall be increased
as necessary so that after making all required deductions (including deductions
applicable to additional sums payable under this Section) the Administrative
Agent or Lender receives an amount equal to the sum it would have received had
no such deductions been made, (ii) the Borrower shall make such deductions and
(iii) the Borrower shall pay the full amount deducted to the relevant
Governmental Authority in accordance with applicable law.

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

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

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

              (e)    Each Foreign Lender shall deliver to the Borrower (with a
copy to the Administrative Agent) two copies of either United States Internal
Revenue Service Form 1001 or Form 4224, or, in the case of a Foreign Lender
claiming exemption from U.S. Federal withholding tax under Section 871(h) or
881(c) of the Code with respect to payments of "portfolio interest", a Form W-8,
or any subsequent versions thereof or successors thereto (and, if such Foreign
Lender delivers a Form W-8, a certificate representing that such Foreign Lender
is not a bank for purposes of Section 881(c) of the Code, is not a ten percent
(10%) shareholder of the Borrower (within the meaning of Section 871(h)(3)(B) of
the Code) and is not a controlled foreign corporation related to the Borrower
(within the meaning of Section 864(d)(4) of the Code)), properly completed and
duly executed by such Foreign Lender claiming complete exemption from, or
reduced rate of, U.S. Federal withholding tax on payments by the Borrower under
this Agreement or any other Loan Document.  Such forms shall be delivered by
each Foreign Lender on or before the date it becomes a party to this Agreement
or designates a new lending office.  In addition, each Foreign Lender shall
deliver such forms promptly upon the obsolescence, expiration or invalidity of
any form previously delivered by such Foreign Lender.  Notwithstanding any other
provision of this Section 2.15, a Foreign Lender shall not be required to
deliver any form pursuant to this Section 2.15 that such Foreign Lender is not
legally able to deliver.

              (f)    If the Administrative Agent or a Lender determines, in its
sole discretion, that it has received a refund of any Taxes as to which it has
been indemnified by the Borrower pursuant to this Section 2.15, it shall pay
over such refund to the Borrower (but only to the extent of indemnity payments
made by the Borrower under this Section 2.15 with respect to the Taxes giving
rise to such refund), net of all reasonable out-of-pocket expenses of the
Administrative Agent or such Lender and without interest (other than any
interest paid by the relevant Governmental Authority with respect to such
refund); PROVIDED, HOWEVER, that the Borrower, upon the request of the
Administrative Agent or such Lender, agrees to repay the amount paid over to the
Borrower (plus any penalties, interest or other charges imposed by the relevant
Governmental Authority) to the Administrative Agent or such Lender in the event
the Administrative Agent or such Lender is required to repay such refund to such
Governmental Authority.  Nothing contained in this Section 2.15 shall require
the Administrative Agent or any Lender to make available its tax returns (or any
other information relating to its Taxes which it deems confidential) to the
Borrower or any other Person.

              Section 2.16. PAYMENTS GENERALLY; PRO RATA TREATMENT; SHARING OF
SET-OFFS.

              (a) The Borrower shall make each payment required to be made by it
hereunder or under any other Loan Document (whether of principal, interest or
fees, or of amounts payable under Sections 2.13, 2.14 or 2.15, or otherwise)
prior to 12:00 noon, New York City time, on the date when due, in immediately
available funds, without set-off or counterclaim. Any amounts received after
such time on any date may, in the discretion of the Administrative Agent, be
deemed to have been received on the next succeeding Business Day for purposes of
calculating interest thereon. All such payments shall be made to the
Administrative Agent at The Chase Manhattan Bank, New York, New York, ABA no.
021000021, account no. 9101449099, phone no. (212) 552-2222 (or such other

9.03 shall be made directly to the Persons entitled thereto and payments
pursuant to

other Loan Documents shall be made to the Persons specified therein. The
Administrative Agent shall distribute any such payments received by it for the
account of any other Person to the appropriate recipient promptly following
receipt thereof. If any payment under any Loan Document shall be due on a day
that is not a Business Day, the date for payment shall be extended to the next
succeeding Business Day, and, in the case of any payment accruing interest,
interest thereon shall be payable for the period of such extension. All payments
under each Loan Document shall be made in dollars.

              (b)    If at any time insufficient funds are received by and
available to the Administrative Agent to pay fully all amounts of principal,
interest and fees then due hereunder, such funds shall be applied (i) first,
towards payment of interest and fe
