Lender's pro rata portion of such payment if such payment is not sufficient to

date toward the reduction of the Revolving Commitments as set forth in Section
2.8(b); provided, that, notwithstanding the foregoing, on each Reinvestment
        --------
Prepayment Date, an amount equal to the Reinvestment Prepayment Amount with
respect to the relevant Reinvestment Event shall be applied toward the reduction
of the Revolving Commitments as set forth in Section 2.8(b); provided further,
                                                             -------- -------
that, the foregoing shall not apply to the sale of inventory by the Borrower or
any of its Subsidiaries in the ordinary course of business.

          (b)  Amounts to be applied in connection with prepayments and
Revolving Commitment reductions made pursuant to Section 2.8 shall be applied to
reduce permanently the Revolving Commitments.  Any such reduction of the
Revolving Commitments shall be accompanied by prepayment of the Revolving Loans
and/or Swingline Loans to the extent, if any, that the Total Revolving
Extensions of Credit exceed the amount of the Total Revolving Commitments as so
reduced, provided that if the aggregate principal amount of Revolving Loans and
         --------
Swingline Loans then outstanding is less than the amount of such excess (because
L/C Obligations constitute a portion thereof), the Borrower shall, to the extent
of the balance of such excess, replace outstanding Letters of Credit and/or
deposit an amount in cash in a cash collateral account established with the
Administrative Agent for the benefit of the Lenders on terms and conditions
satisfactory to the Administrative Agent.  The application of any prepayment
pursuant to Section 2.8 shall be made, first, to ABR Loans and, second, to
                                       -----                    ------
Eurodollar Loans.  Each prepayment of the Loans under Section 2.8 (except in the
case of Revolving Loans that are ABR Loans and Swingline Loans) shall be
accompanied by accrued interest to the date of such prepayment on the amount
prepaid.

          2.9  Conversion and Continuation Options. (a)  The Borrower may elect
               -----------------------------------
from time to time to convert Eurodollar Loans to ABR Loans by giving the
Administrative Agent at least two Business Days' prior irrevocable notice of
such election, provided that any such conversion of Eurodollar Loans may only be
               --------
made on the last day of an Interest Period with respect thereto.  The Borrower
may elect from time to time to convert ABR Loans to Eurodollar Loans by giving
the Administrative Agent at least three Business Days' prior irrevocable notice
of such election
<PAGE>

(which notice shall specify the length of the initial Interest Period therefor),
provided that no ABR Loan may be converted into a Eurodollar Loan when any Event
--------
of Default has occurred and is continuing and the Administrative Agent has
determined in its sole discretion not to permit such conversions. Upon receipt
of any such notice the Administrative Agent shall promptly notify each relevant
Lender thereof.

          (b)  Any Eurodollar Loan may be continued as such upon the expiration
of the then current Interest Period with respect thereto by the Borrower giving
irrevocable notice to the Administrative Agent, in accordance with the
applicable provisions of the term "Interest Period" set forth in Section 1.1, of
the length of the next Interest Period to be applicable to such Loans, provided
                                                                       --------
that no Eurodollar Loan may be continued as such when any Event of Default has
occurred and is continuing and the Administrative Agent has determined in its
sole discretion not to permit such continuations, and provided, further, that if
                                                      --------  -------
the Borrower shall fail to give any required notice as described above in this
paragraph or if such continuation is not permitted pursuant to the preceding
proviso such Loans shall be automatically converted to ABR Loans on the last day
of such then expiring Interest Period.  Upon receipt of any such notice the
Administrative Agent shall promptly notify each relevant Lender thereof.

          2.10 Limitations on Eurodollar Tranches.  Notwithstanding anything to
               ----------------------------------
the contrary in this Agreement, all borrowings, conversions and continuations of
Eurodollar Loans hereunder and all selections of Interest Periods hereunder
shall be in such amounts and be made pursuant to such elections so that, (a)
after giving effect thereto, the aggregate principal amount of the Eurodollar
Loans comprising each Eurodollar Tranche shall be equal to $5,000,000 or a whole
multiple of $1,000,000 in excess thereof and (b) no more than five Eurodollar
Tranches shall be outstanding at any one time.

          2.11 Interest Rates and Payment Dates.  (a)  Each Eurodollar Loan
               --------------------------------
shall bear interest for each day during each Interest Period with respect
thereto at a rate per annum equal to the Eurodollar Rate determined for such day
plus the Applicable Margin.

          (b)  Each ABR Loan shall bear interest at a rate per annum equal to
the ABR plus the Applicable Margin.

          (c)  (i) If all or a portion of the principal amount of any Loan or
Reimbursement Obligation shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum equal to (x) in the case of the Loans, the rate that would
otherwise be applicable thereto pursuant to the foregoing provisions of this
Section plus 2% or (y) in the case of Reimbursement Obligations, the rate
        ----
applicable to ABR Loans plus 2%, and (ii) if all or a portion of any interest
                        ----
payable on any Loan or Reimbursement Obligation or any commitment fee or other
amount payable hereunder shall not be paid when due (whether at the stated
maturity, by acceleration or otherwise), such overdue amount shall bear interest
at a rate per annum equal to the rate then applicable to ABR Loans plus 2%, in
                                                                   ----
each case, with respect to clauses (i) and (ii) above, from the date of such
non-payment until such amount is paid in full (as well after as before
judgment).
<PAGE>

          (d)  Interest shall be payable in arrears on each Interest Payment
Date, provided that interest accruing pursuant to paragraph (c) of this Section
      --------
shall be payable from time to time on demand.

          2.12 Computation of Interest and Fees.  (a)  Interest and fees
               --------------------------------
payable pursuant hereto shall be calculated on the basis of a 360-day year for
the actual days elapsed, except that, with respect to ABR Loans the rate of
interest on which is calculated on the basis of the Prime Rate, the interest
thereon shall be calculated on the basis of a 365- (or 366-, as the case may be)
day year for the actual days elapsed.  The Administrative Agent shall as soon as
practicable notify the Borrower and the relevant Lenders of each determination
of a Eurodollar Rate.  Any change in the interest rate on a Loan resulting from
a change in the ABR or the Eurocurrency Reserve Requirements shall become
effective as of the opening of business on the day on which such change becomes
effective.  The Administrative Agent shall as soon as practicable notify the
Borrower and the relevant Lenders of the effective date and the amount of each
such change in interest rate.

          (b)  Each determination of an interest rate by the Administrative
Agent pursuant to any provision of this Agreement shall be conclusive and
binding on the Borrower and the Lenders in the absence of manifest error.  The
Administrative Agent shall, at the request of the Borrower, deliver to the
Borrower a statement showing the quotations used by the Administrative Agent in
determining any interest rate pursuant to Section 2.11(a).

          2.13 Inability to Determine Interest Rate.  If prior to the first day
               ------------------------------------
of any Interest Period:

          (a)  the Administrative Agent shall have determined (which
     determination shall be conclusive and binding upon the Borrower) that, by
     reason of circumstances affecting the relevant market, adequate and
     reasonable means do not exist for ascertaining the Eurodollar Rate for such
     Interest Period, or

          (b)  the Administrative Agent shall have received notice from the
     Majority Lenders that the Eurodollar Rate determined or to be determined
     for such Interest Period will not adequately and fairly reflect the cost to
     such Lenders (as conclusively certified by such Lenders) of making or
     maintaining their affected Loans during such Interest Period,

the Administrative Agent shall give telecopy or telephonic notice thereof to the
Borrower and the Lenders as soon as practicable thereafter.  If such notice is
given (x) any Eurodollar Loans requested to be made on the first day of such
Interest Period shall be made as ABR Loans, (y) any Loans that were to have been
converted on the first day of such Interest Period to Eurodollar Loans shall be
continued as ABR Loans and (z) any outstanding Eurodollar Loans shall be
converted, on the last day of the then-current Interest Period, to ABR Loans.
Until such notice has been withdrawn by the Administrative Agent, no further
Eurodollar Loans shall be
<PAGE>

made or continued as such, nor shall the Borrower have the right to convert
Loans to Eurodollar Loans.

          2.14 Pro Rata Treatment and Payments.  (a)  Each borrowing by the
               -------------------------------
Borrower from the Lenders hereunder, each payment by the Borrower on account of
any commitment fee and any reduction of the Revolving Commitments of the Lenders
shall be made pro rata according to the Revolving Percentages, of the relevant
              --- ----
Lenders.

          (b)  Each payment (including each prepayment) by the Borrower on
account of principal of and interest on the Revolving Loans shall be made pro
                                                                          ---
rata according to the respective outstanding principal amounts of the Revolving
----
Loans then held by the Revolving Lenders.

          (c)  All payments (including prepayments) to be made by the Borrower
hereunder, whether on account of principal, interest, fees or otherwise, shall
be made without setoff or counterclaim and shall be made prior to 12:00 Noon,
New York City time, on the due date thereof to the Administrative Agent, for the
account of the Lenders, at the Funding Office, in Dollars and in immediately
available funds.  The Administrative Agent shall distribute such payments to the
Lenders promptly upon receipt in like funds as received.  If any payment
hereunder (other than payments on the Eurodollar Loans) becomes due and payable
on a day other than a Business Day, such payment shall be extended to the next
succeeding Business Day.  If any payment on a Eurodollar Loan becomes due and
payable on a day other than a Business Day, the maturity thereof shall be
extended to the next succeeding Business Day unless the result of such extension
would be to extend such payment into another calendar month, in which event such
payment shall be made on the immediately preceding Business Day.  In the case of
any extension of any payment of principal pursuant to the preceding two
sentences, interest thereon shall be payable at the then applicable rate during
such extension.

          (d)  Unless the Administrative Agent shall have been notified in
writing by any Lender prior to a borrowing that such Lender will not make the
amount that would constitute its share of such borrowing available to the
Administrative Agent, the Administrative Agent may assume that such Lender is
making such amount available to the Administrative Agent, and the Administrative
Agent may, in reliance upon such assumption, make available to the Borrower a
corresponding amount.  If such amount is not made available to the
Administrative Agent by the required time on the Borrowing Date therefor, such
Lender shall pay to the Administrative Agent, on demand, such amount with
interest thereon at a rate equal to the daily average Federal Funds Effective
Rate for the period until such Lender makes such amount immediately available to
the Administrative Agent.  A certificate of the Administrative Agent submitted
to any Lender with respect to any amounts owing under this paragraph shall be
conclusive in the absence of manifest error.  If such Lender's share of such
borrowing is not made available to the Administrative Agent by such Lender
within three Business Days of such Borrowing Date, the Administrative Agent
shall also be entitled to recover such amount with interest thereon at the rate
per annum applicable to ABR Loans, on demand, from the Borrower.
<PAGE>

          (e)  Unless the Administrative Agent shall have been notified in
writing by the Borrower prior to the date of any payment being made hereunder
that the Borrower will not make such payment to the Administrative Agent, the
Administrative Agent may assume that the Borrower is making such payment, and
the Administrative Agent may, but shall not be required to, in reliance upon
such assumption, make available to the Lenders their respective pro rata shares
                                                                --- ----
of a corresponding amount.  If such payment is not made to the Administrative
Agent by the Borrower within three Business Days of such required date, the
Administrative Agent shall be entitled to recover, on demand, from each Lender
to which any amount which was made available pursuant to the preceding sentence,
such amount with interest thereon at the rate per annum equal to the daily
average Federal Funds Effective Rate.  Nothing herein shall be deemed to limit
the rights of the Administrative Agent or any Lender against the Borrower.

          2.15 Requirements of Law.  (a)  If the adoption of or any change in
               -------------------
any Requirement of Law or in the interpretation or application thereof or
compliance by any Lender with any request or directive (whether or not having
the force of law) from any central bank or other Governmental Authority made
subsequent to the date hereof:

          (v)   shall subject any Lender to any tax of any kind whatsoever with
     respect to this Agreement, any Letter of Credit, any Application or any
     Eurodollar Loan made by it, or change the basis of taxation of payments to
     such Lender in respect thereof (except for Non-Excluded Taxes covered by
     Section 2.16 and changes in the rate of tax on the overall net income of
     such Lender);

          (vi)  shall impose, modify or hold applicable any reserve, special
     deposit, compulsory loan or similar requirement against assets held by,
     deposits or other liabilities in or for the account of, advances, loans or
     other extensions of credit by, or any other acquisition of funds by, any
     office of such Lender that is not otherwise included in the determination
     of the Eurodollar Rate hereunder; or

          (vii) shall impose on such Lender any other condition; and the result
of any of the foregoing is to increase the cost to such Lender, by an amount
that such Lender deems to be material, of making, converting into, continuing or
maintaining Eurodollar Loans or issuing or participating in Letters of Credit,
or to reduce any amount receivable hereunder in respect thereof, then, in any
such case, the Borrower shall promptly pay such Lender, upon its demand, any
additional amounts necessary to compensate such Lender for such increased cost
or reduced amount receivable. If any Lender becomes entitled to claim any
additional amounts pursuant to this paragraph, it shall promptly notify the
Borrower (with a copy to the Administrative Agent) of the event by reason of
which it has become so entitled.

          (b)  If any Lender shall have determined that the adoption of or any
change in any Requirement of Law regarding capital adequacy or in the
interpretation or application thereof or compliance by such Lender or any
corporation controlling such Lender with any request or directive regarding
capital adequacy (whether or not having the force of law) from any
<PAGE>

Governmental Authority made subsequent to the date hereof shall have the effect
of reducing the rate of return on such Lender's or such corporation's capital as
a consequence of its obligations hereunder or under or in respect of any Letter
of Credit to a level below that which such Lender or such corporation could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or such corporation's policies with respect to capital adequacy)
by an amount deemed by such Lender to be material, then from time to time, after
submission by such Lender to the Borrower (with a copy to the Administrative
Agent) of a written request therefor, the Borrower shall pay to such Lender such
additional amount or amounts as will compensate such Lender for such reduction;
provided that the Borrower shall not be required to compensate a Lender pursuant
--------
to this paragraph for any amounts incurred more than six months prior to the
date that such Lender notifies the Borrower of such Lender's intention to claim
compensation therefor; and provided further that, if the circumstances giving
                           -------- -------
rise to such claim have a retroactive effect, then such six-month period shall
be extended to include the period of such retroactive effect.

          (c)  A certificate as to any additional amounts payable pursuant to
this Section submitted by any Lender to the Borrower (with a copy to the
Administrative Agent) shall be conclusive in the absence of manifest error.  The
obligations of the Borrower pursuant to this Section shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

          2.16 Taxes.  (a)  All payments made by the Borrower under this
               -----
Agreement shall be made free and clear of, and without deduction or withholding
for or on account of, any present or future income, stamp or other taxes,
levies, imposts, duties, charges, fees, deductions or withholdings, now or
hereafter imposed, levied, collected, withheld or assessed by any Governmental
Authority, excluding net income taxes and franchise taxes (imposed in lieu of
net income taxes) imposed on the Administrative Agent or any Lender as a result
of a present or former connection between the Administrative Agent or such
Lender and the jurisdiction of the Governmental Authority imposing such tax or
any political subdivision or taxing authority thereof or therein (other than any
such connection arising solely from the Administrative Agent or such Lender
having executed, delivered or performed its obligations or received a payment
under, or enforced, this Agreement or any other Loan Document).  If any such
non-excluded taxes, levies, imposts, duties, charges, fees, deductions or
withholdings ("Non-Excluded Taxes") or Other Taxes are required to be withheld
               ------------------
from any amounts payable to the Administrative Agent or any Lender hereunder,
the amounts so payable to the Administrative Agent or such Lender shall be
increased to the extent necessary to yield to the Administrative Agent or such
Lender (after payment of all Non-Excluded Taxes and Other Taxes) interest or any
such other amounts payable hereunder at the rates or in the amounts specified in
this Agreement, provided, however, that the Borrower shall not be required to
                --------  -------
increase any such amounts payable to any Lender with respect to any Non-Excluded
Taxes (i) that are attributable to such Lender's failure to comply with the
requirements of paragraph (d) or (e) of this Section or (ii) that are United
States withholding taxes imposed on amounts payable to such Lender at the time
the Lender becomes a party to this Agreement, except to the extent that such
Lender's assignor (if any) was
<PAGE>

entitled, at the time of assignment, to receive additional amounts from the
Borrower with respect to such Non-Excluded Taxes pursuant to this paragraph.

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

          (c)  Whenever any Non-Excluded Taxes or Other Taxes are payable by the
Borrower, as promptly as possible thereafter the Borrower shall send to the
Administrative Agent for its own account or for the account of the relevant
Lender, as the case may be, a certified copy of an original official receipt
received by the Borrower showing payment thereof.  If the Borrower fails to pay
any Non-Excluded Taxes or Other Taxes when due to the appropriate taxing
authority or fails to remit to the Administrative Agent the required receipts or
other required documentary evidence, the Borrower shall indemnify the
Administrative Agent and the Lenders for any incremental taxes, interest or
penalties that may become payable by the Administrative Agent or any Lender as a
result of any such failure.

          (d)  Each Lender (or Transferee) that is not a "U.S. Person" as
defined in Section 7701(a)(30) of the Code (a "Non-U.S. Lender") shall deliver
                                               ---------------
to the Borrower and the Administrative Agent (or, in the case of a Participant,
to the Lender from which the related participation shall have been purchased)
two copies of either U.S. Internal Revenue Service Form W-8BEN or Form W-8ECI,
or, in the case of a Non-U.S. 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 statement substantially in the form of
Exhibit G and a Form W-8BEN, or any subsequent versions thereof or successors
thereto, properly completed and duly executed by such Non-U.S. Lender claiming
complete exemption from, or a reduced rate of, U.S. federal withholding tax on
all payments by the Borrower under this Agreement and the other Loan Documents.
Such forms shall be delivered by each Non-U.S. Lender on or before the date it
becomes a party to this Agreement (or, in the case of any Participant, on or
before the date such Participant purchases the related participation).  In
addition, each Non-U.S. Lender shall deliver such forms promptly upon the
obsolescence or invalidity of any form previously delivered by such Non-U.S.
Lender.  Each Non-U.S. Lender shall promptly notify the Borrower at any time it
determines that it is no longer in a position to provide any previously
delivered certificate to the Borrower (or any other form of certification
adopted by the U.S. taxing authorities for such purpose).  Notwithstanding any
other provision of this paragraph, a Non-U.S. Lender shall not be required to
deliver any form pursuant to this paragraph that such Non-U.S. Lender is not
legally able to deliver.

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

execute and deliver such documentation and in such Lender's judgment such
completion, execution or submission would not materially prejudice the legal
position of such Lender.

          (f)  The agreements in this Section shall survive the termination of
this Agreement and the payment of the Loans and all other amounts payable
hereunder.

          2.17 Indemnity.  The Borrower agrees to indemnify each Lender and to
               ---------
hold each Lender harmless from any loss or expense that such Lender may sustain
or incur as a consequence of (a) default by the Borrower in making a borrowing
of, conversion into or continuation of Eurodollar Loans after the Borrower has
given a notice requesting the same in accordance with the provisions of this
Agreement, (b) default by the Borrower in making any prepayment of or conversion
from Eurodollar Loans after the Borrower has given a notice thereof in
accordance with the provisions of this Agreement or (c) the making of a
prepayment of Eurodollar Loans on a day that is not the last day of an Interest
Period with respect thereto.  Such indemnification may include an amount equal
to the excess, if any, of (i) the amount of interest that would have accrued on
the amount so prepaid, or not so borrowed, converted or continued, for the
period from the date of such prepayment or of such failure to borrow, convert or
continue to the last day of such Interest Period (or, in the case of a failure
to borrow, convert or continue, the Interest Period that would have commenced on
the date of such failure) in each case at the applicable rate of interest for
such Loans provided for herein (excluding, however, the Applicable Margin
included therein, if any) over (ii) the amount of interest (as reasonably
                          ----
determined by such Lender) that would have accrued to such Lender on such amount
by placing such amount on deposit for a comparable period with leading banks in
the interbank eurodollar market.  A certificate as to any amounts payable
pursuant to this Section submitted to the Borrower by any Lender shall be
conclusive in the absence of manifest error.  This covenant shall survive the
termination of this Agreement and the payment of the Loans and all other amounts
payable hereunder.

          2.18 Change of Lending Office.  Each Lender agrees that, upon the
               ------------------------
occurrence of any event giving rise to the operation of Section 2.15 or 2.16(a)
with respect to such Lender, it will, if requested by the Borrower, use
reasonable efforts (subject to overall policy considerations of such Lender) to
designate another lending office for any Loans affected by such event with the
object of avoiding the consequences of such event; provided, that such
                                                   --------
designation is made on terms that, in the sole judgment of such Lender, cause
such Lender and its lending office(s) to suffer no economic, legal or regulatory
disadvantage, and provided, further, that nothing in this Section shall affect
                  --------  -------
or postpone any of the obligations of any Borrower or the rights of any Lender
pursuant to Section 2.15 or 2.16(a).

          2.19 Replacement of Lenders.  The Borrower shall be permitted to
               ----------------------
replace any Lender that (a) requests reimbursement for amounts owing pursuant to
Section 2.15 or 2.16(a) or (b) defaults in its obligation to make Loans
hereunder, with a replacement financial institution; provided that (i) such
                                                     --------
replacement does not conflict with any Requirement of Law, (ii) no Event of
Default shall have occurred and be continuing at the time of such replacement,
(iii) prior to any such replacement, such Lender shall have taken no action
under Section 2.18 so as to
<PAGE>

eliminate the continued need for payment of amounts owing pursuant to Section
2.15 or 2.16(a), (iv) the replacement financial institution shall purchase, at
par, all Loans and other amounts owing to such replaced Lender on or prior to
the date of replacement, (v) the Borrower shall be liable to such replaced
Lender under Section 2.17 if any Eurodollar Loan owing to such replaced Lender
shall be purchased other than on the last day of the Interest Period relating
thereto, (vi) the replacement financial institution, if not already a Lender,
shall be reasonably satisfactory to the Administrative Agent, (vii) the replaced
Lender shall be obligated to make such replacement in accordance with the
provisions of Section 10.6 (provided that the Borrower shall be obligated to pay
the registration and processing fee referred to therein), (viii) until such time
as such replacement shall be consummated, the Borrower shall pay all additional
amounts (if any) required pursuant to Section 2.15 or 2.16(a), as the case may
be, and (ix) any such replacement shall not be deemed to be a waiver of any
rights that the Borrower, the Administrative Agent or any other Lender shall
have against the replaced Lender.

                         SECTION 3.  LETTERS OF CREDIT

          3.1  L/C Commitment.  (a)  Subject to the terms and conditions hereof,
               --------------
the Issuing Lender, in reliance on the agreements of the other Revolving Lenders
set forth in Section 3.4(a), agrees to issue letters of credit ("Letters of
                                                                 ----------
Credit") for the account of the Borrower on any Business Day during the
------
Revolving Commitment Period 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 aggregate amount of the
Available Revolving Commitments would be less than zero.  Each Letter of Credit
shall (i) be denominated in Dollars, (ii) have a face amount of at least
$100,000 (unless otherwise agreed by the Issuing Lender) and (iii) expire no
later than the date that is five Business Days prior to the Revolving
Termination Date.

          (b)  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 Requirement of Law.

          3.2  Procedure for Issuance of Letter of Credit.  The Borrower may
               ------------------------------------------
from time to time request that the Issuing Lender issue a Letter of Credit by
delivering to the Issuing Lender at its address for notices specified herein 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
will 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 promptly issue the Letter of Credit requested
thereby (but in no event shall the Issuing Lender be required to issue any
Letter of Credit earlier than three 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 to by the
Issuing Lender and the Borrower.  The Issuing Lender shall
<PAGE>

furnish a copy of such Letter of Credit to the Borrower promptly following the
issuance thereof. The Issuing Lender shall promptly furnish to the
Administrative Agent, which shall in turn promptly furnish to the Lenders,
notice of the issuance of each Letter of Credit (including the amount thereof).

          3.3  Fees and Other Charges.  (a)  The Borrower will pay a fee on all
               ----------------------
outstanding Letters of Credit at a per annum rate equal to the Applicable Margin
then in effect with respect to Eurodollar Loans, shared ratably among the
Revolving Lenders and payable quarterly in arrears on each L/C Fee Payment Date
after the issuance date.  In addition, the Borrower shall pay to the Issuing
Lender for its own account a fronting fee of .25% per annum on the face amount
of each Letter of Credit, payable quarterly in arrears on each L/C Fee Payment
Date after the Issuance Date, provided that so long as the Issuing Lender is the
                              --------
sole Lender hereunder, the sum of such fronting fee and the fee described in the
preceding sentence shall not exceed a per annum rate equal to the Applicable
Margin then in effect with respect to Eurodollar Loans.

          (b)  In addition to the foregoing fees, the Borrower shall pay or
reimburse the Issuing Lender for such normal and customary costs and expenses as
are incurred or charged by the Issuing Lender in issuing, negotiating, effecting
payment under, amending or otherwise administering any Letter of Credit.

          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 set forth below, for such L/C Participant's
own account and risk an undivided interest equal to such L/C Participant's
Revolving Percentage in the Issuing Lender's obligations and rights under and in
respect of each Letter of Credit issued hereunder 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
Borrower 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
Percentage of the amount of such draft, or any part thereof, that is not so
reimbursed.

          (b)  If 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 is paid to
the Issuing Lender within three Business Days after the date such payment is
due, such L/C Participant shall pay to the Issuing Lender on demand an amount
equal to the product of (i) such amount, times (ii) the daily average Federal
Funds Effective Rate during the period from and including the date such payment
is required 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.  If any
such amount required to be paid by any L/C Participant pursuant to Section
3.4(a) is not made available to the Issuing Lender by such L/C Participant
<PAGE>

within three Business Days after the date such payment is due, the Issuing
Lender shall be entitled to recover from such L/C Participant, on demand, such
amount with interest thereon calculated from such due date at the rate per annum
applicable to ABR Loans.  A certificate of the Issuing Lender submitted to any
L/C Participant with respect to any amounts owing under this Section shall be
conclusive in the absence of manifest error.

          (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 pro
                                                                         ---
rata share of such payment in accordance with Section 3.4(a), the Issuing Lender
----
receives any payment related to such Letter of Credit (whether directly from the
Borrower or otherwise, including proceeds of collateral applied thereto by the
Issuing Lender), or any payment of interest on account thereof, the Issuing
Lender will distribute to such L/C Participant its pro rata share thereof;
                                                   --- ----
provided, however, 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.

          3.5  Reimbursement Obligation of the Borrower.  The Borrower agrees to
               ----------------------------------------
reimburse the Issuing Lender on each date on which the Issuing Lender notifies
the Borrower of the date and amount of a draft presented under any Letter of
Credit and paid by the Issuing Lender for the amount of (a) such draft so paid
and (b) any taxes, fees, charges or other costs or expenses incurred by the
Issuing Lender in connection with such payment.  Each such payment shall be made
to the Issuing Lender at its address for notices specified herein in lawful
money of the United States and in immediately available funds.  Interest shall
be payable on any and all amounts remaining unpaid by the Borrower under this
Section from the date such amounts become payable (whether at stated maturity,
by acceleration or otherwise) until payment in full at the rate set forth in (i)
until the second Business Day following the date of the applicable drawing,
Section 2.11(b) and (ii) thereafter, Section 2.11(c).

          3.6  Obligations Absolute.  The Borrower's obligations under this
               --------------------
Section 3 shall be absolute and unconditional under any and all circumstances
and irrespective of any setoff, counterclaim or defense to payment that the
Borrower may have or have had against the Issuing Lender, any beneficiary of a
Letter of Credit or any other Person.  The Borrower also agrees with the Issuing
Lender that the Issuing Lender shall not be responsible for, and the Borrower's
Reimbursement Obligations under Section 3.5 shall not be affected by, among
other things, the validity or genuineness of 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 Borrower 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 the Borrower against any
beneficiary of such Letter of Credit or any such transferee.  The Issuing Lender
shall not be liable for any error, omission, interruption or 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 found by a final and nonappealable decision of a court of competent
jurisdiction to have resulted from the gross negligence or willful misconduct of
the Issuing Lender.  The Borrower agrees that any action taken or omitted by the
Issuing Lender under or in
<PAGE>

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 Commercial Code of the State of
New York, shall be binding on the Borrower and shall not result in any liability
of the Issuing Lender to the Borrower.

          3.7  Letter of Credit Payments.  If any draft shall be presented for
               -------------------------
payment under any Letter of Credit, the Issuing Lender shall promptly notify the
Borrower of the date and amount thereof.  The responsibility of the Issuing
Lender to the Borrower 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 substantially in conformity with such
Letter of Credit.

          3.8  Applications.  To the extent that any provision of any
               ------------
Application related to any Letter of Credit is inconsistent with the provisions
of this Section 3, the provisions of this Section 3 shall apply.

                  SECTION 4.  REPRESENTATIONS AND WARRANTIES

          To induce the Administrative Agent and the Lenders to enter into this
Agreement and to make the Loans and issue or participate in the Letters of
Credit and the Borrower hereby jointly and severally represent and warrant to
the Administrative Agent and each Lender that:

          4.1  Financial Condition.  (a)  The unaudited pro forma consolidated
               -------------------                      --- -----
balance sheet of the Borrower and its consolidated Subsidiaries as at the
Closing Date, (including the notes thereto) (the "Pro Forma Balance Sheet"),
                                                  -----------------------
copies of which have heretofore been furnished to each Lender, has been prepared
giving effect (as if such events had occurred on such date) to (i) the Loans to
be made on the Closing Date and the use of proceeds thereof and (ii) the payment
of fees and expenses in connection with the foregoing.  The Pro Forma Balance
Sheet has been prepared based on the best information available to the Borrower
as of the date of delivery thereof, and presents fairly on a pro forma basis the
                                                             --- -----
estimated financial position of Borrower and its consolidated Subsidiaries as at
the Closing Date, assuming that the events specified in the preceding sentence
had actually occurred at such date.

          (b)  The audited consolidated balance sheets of the Borrower and its
Subsidiaries as at December 31, 1998, and the related consolidated statements of
income and of cash flows for the fiscal years ended on such dates, reported on
by and accompanied by an unqualified report from KPMG, present fairly the
consolidated financial condition of the Borrower as at such date, and the
consolidated results of its operations and its consolidated cash flows for the
respective fiscal years then ended.  The unaudited interim consolidated balance
sheet of the Borrower and the related unaudited consolidated statements of
income and cash flows for the three-month period ended March 31, 1999, the six-
month period ended June 30, 1999 and the nine-month period ended September 30,
1999, present fairly the consolidated financial condition of the Borrower as at
such date, and the consolidated results of its operations and its consolidated
cash
<PAGE>

flows for the three-month period then ended (subject to normal year-end audit
adjustments). All such financial statements, including the related schedules and
notes thereto, have been prepared in accordance with GAAP applied consistently
throughout the periods involved (except as approved by the aforementioned firm
of accountants and disclosed therein). The Borrower and its Subsidiaries do not
have any material Guarantee Obligations, contingent liabilities and liabilities
for taxes, or any long-term leases or unusual forward or long-term commitments,
including any interest rate or foreign currency swap or exchange transaction or
other obligation in respect of derivatives, that are not reflected in the most
recent financial statements referred to in this paragraph. Except as set forth
in Schedule 4.1, during the period from September 30, 1999 to and including the
date hereof there has been no Disposition by the Borrower of any material part
of its business or property.

          4.2  No Change.  Since September 30, 1999, there has been no
               ---------
development or event that has had or could reasonably be expected to have a
Material Adverse Effect.

          4.3  Corporate Existence; Compliance with Law.  Each of the Borrower
               ----------------------------------------
and its Subsidiaries (a) is duly organized, validly existing and in good
standing under the laws of the jurisdiction of its organization, (b) has the
corporate power and authority, and the legal right, to own and operate its
property, to lease the property it operates as lessee and to conduct the
business in which it is currently engaged, (c) is duly qualified as a foreign
corporation and in good standing under the laws of each jurisdiction where its
ownership, lease or operation of property or the conduct of its business
requires such qualification, except to the extent that the failure to comply
therewith could not, in the aggregate, reasonably be expected to have a Material
Adverse Effect and (d) is in compliance with all Requirements of Law except to
the extent that the failure to comply therewith could not, in the aggregate,
reasonably be expected to have a Material Adverse Effect.

          4.4  Corporate Power; Authorization; Enforceable Obligations.  Each
               -------------------------------------------------------
Loan Party has the corporate power and authority, and the legal right, to make,
deliver and perform the Loan Documents to which it is a party and, in the case
of the Borrower, to obtain extensions of credit hereunder.  Each Loan Party has
taken all necessary corporate action to authorize the execution, delivery and
performance of the Loan Documents to which it is a party and, in the case of the
Borrower, to authorize the extensions of credit on the terms and conditions of
this Agreement.  No consent or authorization of, filing with, notice to or other
act by or in respect of, any Governmental Authority or any other Person is
required in connection with the extensions of credit hereunder or with the
execution, delivery, performance, validity or enforceability of this Agreement
or any of the Loan Documents, except (i) consents, authorizations, filings and
notices described in Schedule 4.4, which consents, authorizations, filings and
notices have been obtained or made and are in full force and effect and (ii) the
filings referred to in Section 4.19.  Each Loan Document has been duly executed
and delivered on behalf of each Loan Party party thereto.  This Agreement
constitutes, and each other Loan Document upon execution will constitute, a
legal, valid and binding obligation of each Loan Party party thereto,
enforceable against each such Loan Party in accordance with its terms, except as
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or similar laws affecting the enforcement of
<PAGE>

creditors' rights generally and by general equitable principles (whether
enforcement is sought by proceedings in equity or at law).

          4.5  No Legal Bar.  The execution, delivery and performance of this
               ------------
Agreement and the other Loan Documents, the issuance of Letters of Credit, the
borrowings hereunder and the use of the proceeds thereof will not violate any
Requirement of Law or any Contractual Obligation of  the Borrower or any of its
Subsidiaries and will not result in, or require, the creation or imposition of
any Lien on any of their respective properties or revenues pursuant to any
Requirement of Law or any such Contractual Obligation (other than the Liens
created by the Security Documents).  No Requirement of Law or Contractual
Obligation applicable to the Borrower or any of its Subsidiaries could
reasonably be expected to have a Material Adverse Effect.

          4.6  Litigation.  No litigation, investigation or proceeding of or
               ----------
before any arbitrator or Governmental Authority is pending or, to the knowledge
of the Borrower, threatened by or against the Borrower or any of its
Subsidiaries or against any of their respective properties or revenues (a) with
respect to any of the Loan Documents or any of the transactions contemplated
hereby or thereby, or (b) that could reasonably be expected to have a Material
Adverse Effect.

          4.7  No Default.  Except as set forth on Schedule 4.7, neither the
               ----------
Borrower nor any of its Subsidiaries is in default under or with respect to any
of its Contractual Obligations in any respect that could reasonably be expected
to have a Material Adverse Effect.  No Default or Event of Default has occurred
and is continuing.

          4.8  Ownership of Property; Liens.  Each of the Borrower and its
               ----------------------------
Subsidiaries has title in fee simple to, or a valid leasehold interest in, all
its real property, and good title to, or a valid leasehold interest in, all its
other property, and none of such property is subject to any Lien except as
permitted by Section 7.3.

          4.9  Intellectual Property.  The Borrower and each of its Subsidiaries
               ---------------------
owns, or is licensed to use, or could obtain the right to use on terms not
materially adverse, all Intellectual Property necessary for the conduct of its
business as currently conducted.  No material claim has been asserted and is
pending by any Person challenging or questioning the use of any Intellectual
Property or the validity or effectiveness of any Intellectual Property, nor does
the Borrower know of any valid basis for any such claim.  The use of
Intellectual Property by the Borrower and its Subsidiaries does not infringe on
the rights of any Person in any respect that could reasonably be expected to
have a Material Adverse Effect.

          4.10 Taxes.  Each of the Borrower and each of its Subsidiaries has
               -----
filed or caused to be filed all Federal, state and other material tax returns
that are required to be filed and has paid all taxes shown to be due and payable
on said returns or on any assessments made against it or any of its property and
all other taxes, fees or other charges imposed on it or any of its property by
any Governmental Authority (other than any the amount or validity of that are
<PAGE>

currently being contested in good faith by appropriate proceedings and with
respect to which reserves in conformity with GAAP have been provided on the
books of the Borrower or its Subsidiaries, as the case may be); no tax Lien has
been filed, and, to the knowledge of the Borrower, no claim is being asserted,
with respect to any such tax, fee or other charge.

          4.11 Federal Regulations.  No part of the proceeds of any Loans, and
               -------------------
no other extensions of credit hereunder, will be used for "buying" or "carrying"
any "margin stock" within the respective meanings of each of the quoted terms
under Regulation U as now and from time to time hereafter in effect or for any
purpose that violates the provisions of the Regulations of the Board.  If
requested by any Lender or the Administrative Agent, the Borrower will furnish
to the Administrative Agent and each Lender a statement to the foregoing effect
in conformity with the requirements of Form G-3 or Form U-1, as applicable,
referred to in Regulation U.

          4.12 Labor Matters.  Except as, in the aggregate, could not
               -------------
reasonably be expected to have a Material Adverse Effect:  (a) there are no
strikes or other labor disputes against the Borrower or any of its Subsidiaries
pending or, to the knowledge of the Borrower, threatened; (b) hours worked by
and payment made to employees of the Borrower and its Subsidiaries have not been
in violation of the Fair Labor Standards Act or any other applicable Requirement
of Law dealing with such matters; and (c) all payments due from the Borrower or
any of its Subsidiaries on account of employee health and welfare insurance have
been paid or accrued as a liability on the books of the Borrower or the relevant
Subsidiary.

          4.13 ERISA.  Neither a Reportable Event nor an "accumulated funding
               -----
deficiency" (within the meaning of Section 412 of the Code or Section 302 of
ERISA) has occurred during the five-year period prior to the date on which this
representation is made or deemed made with respect to any Plan, and each Plan
has complied in all material respects with the applicable provisions of ERISA
and the Code.  No termination of a Single Employer Plan has occurred, and no
Lien in favor of the PBGC or a Plan has arisen, during such five-year period.
The present value of all accrued benefits under each Single Employer Plan (based
on those assumptions used to fund such Plans) did not, as of the last annual
valuation date prior to the date on which this representation is made or deemed
made, exceed the value of the assets of such Plan allocable to such accrued
benefits by a material amount.  Neither the Borrower nor any Commonly Controlled
Entity has had a complete or partial withdrawal from any Multiemployer Plan that
has resulted or could reasonably be expected to result in a material liability
under ERISA, and neither the Borrower nor any Commonly Controlled Entity would
become subject to any material liability under ERISA if the Borrower or any such
Commonly Controlled Entity were to withdraw completely from all Multiemployer
Plans as of the valuation date most closely preceding the date on which this
representation is made or deemed made.  No such Multiemployer Plan is in
Reorganization or Insolvent.

          4.14 Investment Company Act; Other Regulations.  No Loan Party is an
               -----------------------------------------
"investment company", or a company "controlled" by an "investment company",
within the meaning of the Investment Company Act of 1940, as amended.  No Loan
Party is subject to
<PAGE>

regulation under any Requirement of Law (other than Regulation X of the Board)
that limits its ability to incur Indebtedness.

          4.15 Subsidiaries.  Except as disclosed to the Administrative Agent
               ------------
by the Borrower in writing from time to time after the Closing Date, (a)
Schedule 4.15 sets forth the name and jurisdiction of incorporation of each
Subsidiary and, as to each such Subsidiary, the percentage of each class of
Capital Stock owned by any Loan Party and (b) there are no outstanding
subscriptions, options, warrants, calls, rights or other agreements or
commitments (other than stock options granted to employees or directors and
directors' qualifying shares) of any nature relating to any Capital Stock of the
Borrower or any Subsidiary, except as created by the Loan Documents.

          4.16 Use of Proceeds.  The proceeds of the Revolving Loans and the
               ---------------
Swingline Loans, and the Letters of Credit, shall be used (a) to refinance the
existing working capital facility of the Borrower, (b) for the construction,
expansion, development or acquisition of telecommunication related assets and
(c) for working capital and general corporate purposes of the Borrower and its
Subsidiaries in the ordinary course of business.

          4.17 Environmental Matters.  Except as, in the aggregate, could not
               ---------------------
reasonably be expected to have a Material Adverse Effect:

          (a)  To the best of the Borrower's knowledge, the facilities and
     properties owned, leased or operated by the Borrower or any of its
     Subsidiaries (the "Properties") do not contain, and have not previously
                        ----------
     contained during the time of Borrower's control and use thereof, any
     Materials of Environmental Concern in amounts or concentrations or under
     circumstances that constitute or constituted a violation of, or could give
     rise to liability under, any Environmental Law;

          (b)  except as set forth on Schedule 4.17, neither the Borrower nor
     any of its Subsidiaries has received or is aware of any notice of
     violation, alleged violation, non-compliance, liability or potential
     liability regarding environmental matters or compliance with Environmental
     Laws with regard to any of the Properties or the business operated by the
     Borrower or any of its Subsidiaries (the "Business"), nor does the Borrower
                                               --------
     have knowledge or reason to believe that any such notice will be received
     or is being threatened;

          (c)  Materials of Environmental Concern have not been transported or
     disposed of by Borrower from the Properties in violation of, or in a manner
     or to a location that could give rise to liability under, any Environmental
     Law, nor have any Materials of Environmental Concern been generated,
     treated, stored or disposed of at, on or under any of the Properties in
     violation of, or in a manner that could give rise to liability under, any
     applicable Environmental Law;
<PAGE>

          (d)  no judicial proceeding or governmental or administrative action
     is pending or, to the knowledge of the Borrower, threatened, under any
     Environmental Law to which the Borrower or any Subsidiary is or will be
     named as a party with respect to the Properties or the Business, nor are
     there any consent decrees or other decrees, consent orders, administrative
     orders or other orders, or other administrative or judicial requirements
     outstanding under any Environmental Law with respect to the Properties or
     the Business;

          (e)  there has been no release or threat of release of Materials of
     Environmental Concern at or from the Properties, or arising from or related
     to the operations of the Borrower or any Subsidiary in connection with the
     Properties or otherwise in connection with the Business, in violation of or
     in amounts or in a manner that could give rise to liability under
     Environmental Laws;

          (f)  to the best of the Borrower's knowledge, the Properties and all
     operations at the Properties by Borrower are in compliance, with all
     applicable Environmental Laws, and there is no contamination at, under or
     about the Properties or violation of any Environmental Law with respect to
     the Properties or the Business; and

          (g)  neither the Borrower nor any of its Subsidiaries has assumed any
     liability of any other Person under Environmental Laws.

          4.18 Accuracy of Information, etc.  No statement or information
               ----------------------------
contained in this Agreement, any other Loan Document, or any other document,
certificate or statement furnished by or on behalf of any Loan Party to the
Administrative Agent or the Lenders, or any of them, for use in connection with
the transactions contemplated by this Agreement or the other Loan Documents when
taken together with all other such statements and information furnished,
contained as of the date such statement, information, document or certificate
was so furnished, any untrue statement of a material fact or omitted to state a
material fact necessary to make the statements contained herein or therein not
misleading.  The projections and pro forma financial information contained in
                                 --- -----
the materials referenced above are based upon good faith estimates and
assumptions believed by management of the Borrower to be reasonable at the time
made, it being recognized by the Lenders that such financial information as it
relates to future events is not to be viewed as fact and that actual results
during the period or periods covered by such financial information may differ
from the projected results set forth therein by a material amount.  There is no
fact known to any Loan Party that could reasonably be expected to have a
Material Adverse Effect that has not been expressly disclosed herein, in the
other Loan Documents or in any other documents, certificates and statements
furnished to the Administrative Agent and the Lenders for use in connection with
the transactions contemplated hereby and by the other Loan Documents.

          4.19 Security Documents.  The Guarantee and Collateral Agreement is
               ------------------
effective to create in favor of the Administrative Agent, for the benefit of the
Lenders, a legal, valid and enforceable security interest in the Collateral (as
such security interest and such Collateral are described therein) and proceeds
thereof.  In the case of the Pledged Stock described in the
<PAGE>

Guarantee and Collateral Agreement, when stock certificates representing such
Pledged Stock are delivered to the Administrative Agent, and in the case of the
other Collateral described in the Guarantee and Collateral Agreement, when
financing statements and other filings specified on Schedule 4.19 in appropriate
form are filed in the offices specified on Schedule 4.19, the Guarantee and
Collateral Agreement shall constitute a fully perfected Lien on, and security

incurrence of all Indebtedness and obligations being incurred in connection

          4.21 Year 2000 Matters.  Any reprogramming required to permit the
               -----------------
proper functioning (but only to the extent that such proper functioning would
otherwise be impaired by the occurrence of the year 2000) in and following the
year 2000 of computer systems and other equipment containing embedded
microchips, in either case owned or operated by the Borrower or any of its
Subsidiaries or used or relied upon in the conduct of their business (including
any such systems and other equipment supplied by others or with which the
computer systems of the Borrower or any of its Subsidiaries interface), and the
testing of all such systems and other equipment as so reprogrammed, have been
completed.  The costs to the Borrower and its Subsidiaries for such
reprogramming and testing and for the other reasonably foreseeable consequences
to them of any improper functioning of other computer systems and equipment
containing embedded microchips due to the occurrence of the year 2000 could not
reasonably be expected to result in a Default or Event of Default or to have a
Material Adverse Effect.  The computer systems of the Borrower and its
Subsidiaries are and, with ordinary course upgrading and maintenance, will
continue for the term of this Agreement to be, sufficient for the conduct of
their business as currently conducted.

          (i)  any of the Security Documents shall cease, for any reason, to be
     in full force and effect, or any Loan Party or any Affiliate of any Loan
     Party shall so assert, or any
<PAGE>

     Lien created by any of the Security Documents shall cease to be enforceable
     and of the same effect and priority purported to be created thereby; or

          (j)  the guarantee contained in Section 2 of the Guarantee and
     Collateral Agreement shall cease, for any reason, to be in full force and
     effect or any Loan Party or any Affiliate of any Loan Party shall so
     assert; or

          (k) (i)  the Permitted Investors shall cease to own of record and
     beneficially an amount of common stock of the Borrower equal to at least
     33% of the amount of common stock of the Borrower owned by the Permitted
     Investors of record and beneficially as of the Closing Date; (ii) any
     "person" or "group" (as such terms are used in Sections 13(d) and 14(d) of
     the Securities Exchange Act of 1934, as amended (the "Exchange Act")),
     excluding the Permitted Investors, shall become, or obtain rights (whether
     by means or warrants, options or otherwise) to become, the "beneficial
     owner" (as defined in Rules 13(d)-3 and 13(d)-5 under the Exchange Act),
     directly or indirectly, of more than the greater of (x) 20% or (y) the

     Indebtedness or other liabilities or financial obligations, except (x)
     nonconsensual obligations imposed by operation of law, (y) pursuant to the
     Loan Documents to which it is a party and (z) obligations with respect to
     its Capital Stock, or (iii) own, lease, manage or otherwise operate any
     properties or assets (including cash (other than cash received in
     connection with dividends made by the Borrower in accordance with Section
     7.6 pending application in the manner contemplated by said Section) and
     cash equivalents) other than the ownership of shares of Capital Stock of
     the Borrower;

then, and in any such event, (A) if such event is an Event of Default specified
in clause (i) or (ii) of paragraph (f) above with respect to the Borrower,
automatically the Revolving Commitments shall immediately terminate and the
Loans hereunder (with accrued interest thereon) and all other amounts owing
under this Agreement and the other Loan Documents (including all amounts of L/C
Obligations, whether or not the beneficiaries of the then outstanding Letters of
Credit shall have presented the documents required thereunder) shall immediately
become due and payable, and (B) if such event is any other Event of Default,
either or both of the following actions may be taken: (i) 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 Borrower
declare the Revolving Commitments to be terminated forthwith, whereupon the
Revolving Commitments shall immediately terminate; and (ii) with the consent of
the Required Lenders, the Administrative
<PAGE>

Agent may, or upon the request of the Required Lenders, the Administrative Agent
shall, by notice to the Borrower, declare the Loans hereunder (with accrued
interest thereon) and all other amounts owing under this Agreement and the other
Loan Documents (including all amounts of L/C Obligations, whether or not the
beneficiaries of the then outstanding Letters of Credit shall have presented the
documents required thereunder) to be due and payable forthwith, whereupon the
same shall immediately become due and payable. 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 this paragraph, the Borrower shall at
such time 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
by the Administrative Agent to the payment of drafts drawn under such Letters of
Credit, and the unused portion thereof after all such Letters of Credit shall
have expired or been fully drawn upon, if any, shall be applied to repay other
obligations of the Borrower hereunder and under the other Loan Documents. After
all such Letters of Credit shall have expired or been fully drawn upon, all
Reimbursement Obligations shall have been satisfied and all other obligations of
the Borrower hereunder and under the other Loan Documents shall have been paid
in full, the balance, if any, in such cash collateral account shall be returned
to the Borrower (or such other Person as may be lawfully entitled thereto).
Except as expressly provided above in this Section, presentment, demand, protest
and all other notices of any kind are hereby expressly waived by the Borrower.


                     SECTION 9.  THE ADMINISTRATIVE AGENT

          9.1  Appointment.  Each Lender hereby irrevocably designates and
               -----------
appoints the Administrative Agent as the agent of such Lender under this
Agreement and the other Loan Documents, and each such Lender irrevocably
authorizes the Administrative Agent, in such capacity, 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 the Administrative Agent by the terms of this Agreement and the other Loan
Documents, together with such other powers as are reasonably incidental thereto.
Notwithstanding any provision to the contrary elsewhere in this Agreement, the
Administrative Agent shall not have any duties or responsibilities, except those
expressly set forth herein, or any fiduciary relationship with any Lender, and
no implied covenants, functions, responsibilities, duties, obligations or
liabilities shall be read into this Agreement or any other Loan Document or
otherwise exist against the Administrative Agent.

          9.2  Delegation of Duties.  The Administrative Agent may execute any
               --------------------
of its 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
concerning all matters pertaining to such duties. The Administrative Agent shall
not be responsible for the negligence or misconduct of any agents or attorneys
in-fact selected by it with reasonable care.

          9.3  Exculpatory Provisions.  Neither The Administrative Agent nor any
               ----------------------
of its respective officers, directors, employees, agents, attorneys-in-fact or
affiliates shall be (i) liable
<PAGE>

for any action lawfully taken or omitted to be taken by it or such Person under
or in connection with this Agreement or any other Loan Document (except to the
extent that any of the foregoing are found by a final and nonappealable decision
of a court of competent jurisdiction to have resulted from its or such Person's
own gross negligence or willful misconduct) or (ii) responsible in any manner to
any of the Lenders for any recitals, statements, representations or warranties
made by any Loan Party or any officer thereof contained in this Agreement or any
other Loan Document or in any certificate, report, statement or other document
referred to or provided for in, or received by the Administrative Agent under or
in connection with, this Agreement or any other Loan Document or for the value,
validity, effectiveness, genuineness, enforceability or sufficiency of this
Agreement or any other Loan Document or for any failure of any Loan Party a
party thereto to perform its obligations hereunder or thereunder. The
Administrative Agent shall not be under any obligation to any Lender to
ascertain or to inquire as to the observance or performance of any of the
agreements contained in, or conditions of, this Agreement or any other Loan
Document, or to inspect the properties, books or records of any Loan Party.

          9.4  Reliance by Administrative Agent.  The Administrative Agent shall
               --------------------------------
be entitled to rely, and shall be fully protected in relying, upon any
instrument, writing, resolution, notice, consent, certificate, affidavit,
letter, telecopy, telex or teletype message, statement, order or other document
or conversation believed by it to be genuine and correct and to have been
signed, sent or made by the proper Person or Persons and upon advice and
statements of legal counsel (including counsel to the Borrower), independent
accountants and other experts selected by the Administrative Agent. The
Administrative Agent may deem and treat the payee of any Note as the owner
thereof for all purposes unless a written notice of assignment, negotiation or
transfer thereof shall have been filed with the Administrative Agent. The
Administrative Agent shall be fully justified in failing or refusing to take any
action under this Agreement or any other Loan Document unless it shall first
receive such advice or concurrence of the Required Lenders (or, if so specified
by this Agreement, all Lenders) as it deems appropriate or it shall first be
indemnified to its satisfaction by the Lenders against any and all liability and
expense that may be incurred by it by reason of taking or continuing to take any
such action. The Administrative Agent shall in all cases be fully protected in
acting, or in refraining from acting, under this Agreement and the other Loan
Documents in accordance with a request of the Required Lenders (or, if so
specified by this Agreement, all 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 Loans.

          9.5  Notice of Default.  The Administrative Agent shall not be deemed
               -----------------
to have knowledge or notice of the occurrence of any Default or Event of Default
hereunder unless the Administrative Agent has received notice from a Lender or
the Borrower referring to this Agreement, describing such Default or Event of
Default and stating that such notice is a "notice of default". In the event that
the Administrative Agent receives such a notice, the Administrative Agent shall
give notice thereof to the Lenders. The Administrative Agent shall take such
action with respect to such Default or Event of Default as shall be reasonably
directed by the Required Lenders (or, if so specified by this Agreement, all
Lenders); provided that unless and until the Administrative Agent shall have
          --------
received such directions, the Administrative Agent may (but
<PAGE>

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.

          9.6  Non-Reliance on the Administrative Agent and Other Lenders.  Each
               ----------------------------------------------------------
Lender expressly acknowledges that neither the Administrative Agent nor any of
its respective officers, directors, employees, agents, attorneys-in-fact or
affiliates have made any representations or warranties to it and that no act by
the Administrative Agent hereafter taken, including any review of the affairs of
a Loan Party or any affiliate of a Loan Party, shall be deemed to constitute any
representation or warranty by any Agent to any Lender. Each Lender represents to
the Administrative Agent that it has, independently and without reliance upon
any Administrative 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 Loan Parties and their affiliates and made
its own decision to make its Loans hereunder and enter into this Agreement. Each
Lender also represents that it will, independently and without reliance upon the
Administrative 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 Loan Parties and their
affiliates. Except for notices, reports and other documents expressly required
to be furnished to the Lenders by the Administrative Agent hereunder, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the business, operations,
property, condition (financial or otherwise), prospects or creditworthiness of
any Loan Party or any affiliate of a Loan Party that may come into the
possession of the Administrative Agent or any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates.

          9.7  Indemnification.  The Lenders agree to indemnify the
               ---------------
Administrative Agent in its capacity as such (to the extent not reimbursed by
the Borrower and without limiting the obligation of the Borrower to do so),
ratably according to their respective Aggregate Exposure Percentages in effect
on the date on which indemnification is sought under this Section (or, if
indemnification is sought after the date upon which the Revolving Commitments
shall have terminated and the Loans shall have been paid in full, ratably in
accordance with such Aggregate Exposure Percentages immediately prior to such
date), from and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses or disbursements of any
kind whatsoever that may at any time (whether before or after the payment of the
Loans) be imposed on, incurred by or asserted against the Administrative Agent
in any way relating to or arising out of, the Revolving Commitments, this
Agreement, any of the other Loan Documents or any documents contemplated by or
referred to herein or therein or the transactions contemplated hereby or thereby
or any action taken or omitted by the Administrative 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
that are found by a final and nonappealable
<PAGE>

decision of a court of competent jurisdiction to have resulted from the
Administrative Agent's gross negligence or willful misconduct. The agreements in
this Section shall survive the payment of the Loans and all other amounts
payable hereunder.

          9.8  Administrative Agent in Its Individual Capacity.  The
               -----------------------------------------------
Administrative Agent and its affiliates may make loans to, accept deposits from
and generally engage in any kind of business with any Loan Party as though the
Administrative Agent were not an Administrative Agent. With respect to its Loans
made or renewed by it and with respect to any Letter of Credit issued or
participated in by it, the Administrative 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 the Administrative Agent, and the terms
"Lender" and "Lenders" shall include the Administrative Agent in its individual
capacity.

          9.9  Successor Administrative Agent.  The Administrative Agent may
               ------------------------------
resign as Administrative Agent upon 10 days' notice to the Lenders and the
Borrower. If the Administrative Agent shall resign as Administrative Agent under
this Agreement and the other Loan Documents, then the Required Lenders shall
appoint from among the Lenders a successor agent for the Lenders, which
successor agent shall (unless an Event of Default under Section 8(a) or Section
8(f) with respect to the Borrower shall have occurred and be continuing) be
subject to approval by the Borrower (which approval shall not be unreasonably
withheld or delayed), whereupon such successor agent shall succeed to the
rights, powers and duties of the Administrative Agent, and the term
"Administrative Agent" shall mean such successor agent effective upon such
appointment and approval, and the former Administrative Agent's rights, powers
and duties as Administrative Agent shall be terminated, without any other or
further act or deed on the part of such former Administrative Agent or any of
the parties to this Agreement or any holders of the Loans. If no successor agent
has accepted appointment as Administrative Agent by the date that is 10 days
following a retiring Administrative Agent's notice of resignation, the retiring
Administrative Agent's resignation shall nevertheless thereupon become effective
and the Lenders shall assume and perform all of the duties of the Administrative
Agent hereunder until such time, if any, as the Required Lenders appoint a
successor agent as provided for above. After any retiring Administrative Agent's
resignation as Administrative Agent, the provisions of this Section 9 shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Administrative Agent under this Agreement and the other Loan Documents.

                          SECTION 10.  MISCELLANEOUS
<PAGE>

          10.1  Amendments and Waivers.  Neither this Agreement, any other Loan
                ----------------------
Document, nor any terms hereof or thereof may be amended, supplemented or
modified except in accordance with the provisions of this Section 10.1. The
Required Lenders and each Loan Party to the relevant Loan Document may, or, with
the written consent of the Required Lenders, the Administrative Agent and each
Loan Party to the relevant Loan Document may, from time to time, (a) enter into
written amendments, supplements or modifications hereto and to the other Loan
Documents for the purpose of adding any provisions to this Agreement or the
other Loan Documents or changing in any manner the rights of the Lenders or of
the Loan Parties hereunder or thereunder or (b) waive, on such terms and
conditions as the Required Lenders or the Administrative Agent, as the case may
be, may specify in such instrument, any of the requirements of this Agreement or
the other Loan Documents or any Default or Event of Default and its
consequences; provided, however, that no such waiver and no such amendment,
              --------  -------
supplement or modification shall (i) forgive the principal amount or extend the
final scheduled date of maturity of any Loan, reduce the stated rate of any
interest or fee payable hereunder (except (x) in connection with the waiver of
applicability of any post-default increase in interest rates, which waiver shall
be effective with the consent of the Majority Lenders) and (y) that any
amendment or modification of defined terms used in the financial covenants in
this Agreement shall not constitute a reduction in the rate of interest or fees
for purposes of this clause (i)) or extend the scheduled date of any payment
thereof, or extend the expiration date of any Lender's Revolving Commitment, in
each case without the written consent of each Lender directly affected thereby;
(ii) eliminate or reduce the voting rights of any Lender under this Section 10.1
without the written consent of such Lender; (iii) reduce any percentage
specified in the definition of Required Lenders, consent to the assignment or
transfer by the Borrower of any of its rights and obligations under this
Agreement and the other Loan Documents, release all or substantially all of the
Collateral or release all or substantially all of the Subsidiary Guarantors from
their obligations under the Guarantee and Collateral Agreement, in each case
without the written consent of all Lenders; (iv) amend, modify or waive any
condition precedent to any extension of credit set forth in Section 5.2
(including in connection with any waiver of an existing Default or Event of
Default) without the written consent of the Majority Lenders; (v) amend, modify
or waive any provision of Section 2.14 without the written consent of the
Majority Lenders; (vi) reduce the amount of Net Cash Proceeds required to be
applied to prepay Loans under this Agreement without the written consent of the

Majority Lenders without the written consent of all Lenders; (viii) amend,
modify or waive any provision of Section 9 without the written consent of the
Administrative Agent; (ix) amend, modify or waive any provision of Section 2.3
or 2.4 without the written consent of the Swingline Lender; or (x) amend, modify
or waive any provision of Section 3 without the written consent of the Issuing
Lender. Any such waiver and any such amendment, supplement or modification shall
apply equally to each of the Lenders and shall be binding upon the Loan Parties,
the Lenders, the Administrative Agent and all future holders of the Loans. In
the case of any waiver, the Loan Parties, the Lenders and the Administrative
Agent shall be restored to their former position and rights hereunder and under
the other Loan Documents, and any Default or Event of Default waived shall be
deemed to be cured and not continuing; but no such waiver shall extend to any
subsequent or other Default or Event of Default, or impair any right consequent
thereon.
<PAGE>

          For the avoidance of doubt, this Agreement may be amended (or amended
and restated) with the written consent of the Required Lenders, the
Administrative Agent and the Borrower (a) to add one or more additional credit
facilities to this Agreement and to permit the extensions of credit from time to
time outstanding thereunder and the accrued interest and fees in respect thereof
(collectively, the "Additional Extensions of Credit") to share ratably in the
                    -------------------------------
benefits of this Agreement and the other Loan Documents with the Revolving
Extensions of Credit and the accrued interest and fees in respect thereof and
(b) to include appropriately the Lenders holding such credit facilities in any
determination of the Required Lenders and Majority Lenders; provided, that no
                                                            --------
such amendment shall permit the Additional Extensions of Credit to share ratably
with or with preference to the Revolving Extensions of Credit without the
consent of the Majority Lenders.

or reimburse the Administrative Agent for all its out-of-pocket costs and

-----------    --------
any Indemnitee with respect to Indemnified Liabilities to the extent such

transfer any of its rights or obligations under this Agreement without the prior
written consent of each Lender.

          (b)  Any Lender other than any Conduit Lender may, without the consent
of the Borrower, in accordance with applicable law, at any time sell to one or
more banks, financial institutions or other entities (each, a "Participant")
                                                               -----------
participating interests in any Loan owing to such Lender, any Revolving
Commitment of such Lender or any other interest of such Lender hereunder and
under the other Loan Documents. In the event of any such sale by a Lender of a
participating interest to a Participant, such Lender's obligations under this
Agreement to the other parties to this Agreement shall remain unchanged, such
Lender shall remain solely responsible for the performance thereof, such Lender
shall remain the holder of any such Loan for all purposes under this Agreement
and the other Loan Documents, and the Borrower and the Administrative Agent
shall continue to deal solely and directly with such Lender in connection with
such Lender's rights and obligations under this Agreement and the other Loan
Documents. In no event shall any Participant under any such participation have
any right to approve any amendment or waiver of any provision of any Loan
Document, or any consent to any departure by any Loan Party therefrom, except to
the extent that such amendment, waiver or consent would reduce the principal of,
or interest on, the Loans or any fees payable hereunder, or postpone the
<PAGE>

date of the final maturity of the Loans, in each case to the extent subject to
such participation. The Borrower agrees that if amounts outstanding under this
Agreement and the Loans are due or unpaid, or shall have been declared or shall
have become due and payable upon the occurrence of an Event of Default, each
Participant shall, to the maximum extent permitted by applicable law, be deemed
to have the right of setoff in respect of its participating interest in amounts
owing under this Agreement to the same extent as if the amount of its
participating interest were owing directly to it as a Lender under this
Agreement, provided that, in purchasing such participating interest, such
           --------
Participant shall be deemed to have agreed to share with the Lenders the
proceeds thereof as provided in Section 10.7(a) as fully as if it were a Lender
hereunder. The Borrower also agrees that each Participant shall be entitled to
the benefits of Sections 2.15, 2.16 and 2.17 with respect to its participation
in the Revolving Commitments and the Loans outstanding from time to time as if
it was a Lender; provided that, in the case of Section 2.16, such Participant
                 --------
shall have complied with the requirements of said Section and provided, further,
                                                              --------  -------
that no Participant shall be entitled to receive any greater amount pursuant to
any such Section than the transferor Lender would have been entitled to receive
in respect of the amount of the participation transferred by such transferor
Lender to such Participant had no such transfer occurred.

          (c)  Any Lender other than any Conduit Lender (an "Assignor") may, in
                                                             --------
accordance with applicable law, at any time and from time to time assign to any
Lender, any affiliate of any Lender or any Approved Fund or, with the consent of
the Borrower and the Administrative Agent (which, in each case, shall not be
unreasonably withheld or delayed), to an additional bank, financial institution
or other entity (an "Assignee") all or any part of its rights and obligations
                     --------
under this Agreement and the other Loan Documents pursuant to an Assignment and
Acceptance, executed by such Assignee, such Assignor and any other Person whose
consent is required pursuant to this paragraph, and delivered to the
Administrative Agent for its acceptance and recording in the Register; provided
                                                                       --------
that no such assignment to an Assignee (other than any Lender, any affiliate of
any Lender or any Approved Fund) shall be in an aggregate principal amount of
less than $5,000,000 (other than in the case of an assignment of all of a
Lender's interests under this Agreement), unless otherwise agreed by the
Borrower and the Administrative Agent.  For purposes of the proviso contained in
the preceding sentence, the amount described therein shall be aggregated in
respect of each Lender and its related Approved Funds, if any.  Upon such
execution, delivery, acceptance and recording, from and after the effective date
determined pursuant to such Assignment and Acceptance, (x) the Assignee
thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a Revolving Commitment and/or Loans as set forth therein, and (y) the
Assignor thereunder shall, to the extent provided in such Assignment and
Acceptance, be released from its obligations under this Agreement (and, in the
case of an Assignment and Acceptance covering all of an Assignor's rights and
obligations under this Agreement, such Assignor shall cease to be a party
hereto).  Notwithstanding any provision of this Section 10.6, the consent of the
Borrower shall not be required for any assignment that occurs when an Event of
Default pursuant to Section 8(f) shall have occurred and be continuing with
respect to the Borrower.  Notwithstanding the foregoing, any Conduit Lender may
assign at any time to its designating Lender hereunder without the
<PAGE>

consent of the Borrower or the Administrative Agent any or all of the Loans it
may have funded hereunder and pursuant to its designation agreement and without
regard to the limitations set forth in the first sentence of this Section
10.6(c).

          (d)  The Administrative Agent shall, on behalf of the Borrower,
maintain at its address referred to in Section 10.2 a copy of each Assignment
and Acceptance delivered to it and a register (the "Register") for the
                                                    --------
recondition of the names and addresses of the Lenders and the Revolving
Commitment of, and the principal amount of the Loans owing to, each Lender from
time to time. The entries in the Register shall be conclusive, in the absence of
manifest error, and the Borrower, each other Loan Party, the Administrative
Agent and the Lenders shall treat each Person whose name is recorded in the
Register as the owner of the Loans and any Notes evidencing the Loans recorded
therein for all purposes of this Agreement. Any assignment of any Loan, whether
or not evidenced by a Note, shall be effective only upon appropriate entries
with respect thereto being made in the Register (and each Note shall expressly
so provide). Any assignment or transfer of all or part of a Loan evidenced by a
Note shall be registered on the Register only upon surrender for registration of
assignment or transfer of the Note evidencing such Loan, accompanied by a duly
executed Assignment and Acceptance, and thereupon one or more new Notes shall be
issued to the designated Assignee.

          (e)  Upon its receipt of an Assignment and Acceptance executed by an
Assignor, an Assignee and any other Person whose consent is required by Section
10.6(c), together with payment to the Administrative Agent of a registration and
processing fee of $4,000, the Administrative Agent shall (i) promptly accept
such Assignment and Acceptance and (ii) record the information contained therein
in the Register on the effective date determined pursuant thereto.

          (f)  For avoidance of doubt, the parties to this Agreement acknowledge
that the provisions of this Section 10.6 concerning assignments of Loans and
Notes relate only to absolute assignments and that such provisions do not
prohibit assignments creating security interests, including any pledge or
assignment by a Lender of any Loan or Note to any Federal Reserve Bank in
accordance with applicable law.

          (g)  The Borrower, upon receipt of written notice from the relevant
Lender, agrees to issue Notes to any Lender requiring Notes to facilitate
transactions of the type described in paragraph (f) above.

          (h)  Each of the Borrower, each Lender and the Administrative Agent
hereby confirms that it will not institute against a Conduit Lender or join any
other Person in instituting against a Conduit Lender any bankruptcy,
reorganization, arrangement, insolvency or liquidation proceeding under any
state bankruptcy or similar law, for one year and one day after the payment in
full of the latest maturing commercial paper note issued by such Conduit Lender;
provided, however, that each Lender designating any Conduit Lender hereby agrees
--------
to indemnify, save and hold harmless each other party hereto for any loss, cost,
damage or expense arising out of its
<PAGE>

inability to institute such a proceeding against such Conduit Lender during such
period of forbearance.

          10.7  Adjustments; Set-off.  (a)  Except to the extent that this
                --------------------
Agreement expressly provides for payments to be allocated to a particular
Lender, if any Lender (a "Benefitted Lender") shall, at any time after the Loans
                          -----------------
and other amounts payable hereunder shall immediately become due and payable
pursuant to Section 8, receive any payment of all or part of the Obligations
owing to it, or receive any collateral in respect thereof (whether voluntarily
or involuntarily, by set-off, pursuant to events or proceedings of the nature
referred to in Section 8(f), or otherwise), in a greater proportion than any
such payment to or collateral received by any other Lender, if any, in respect
of the Obligations owing to such other Lender, such Benefitted Lender shall
purchase for cash from the other Lenders a participating interest in such
portion of the Obligations owing to each such other Lender, or shall provide
such other Lenders with the benefits of any such collateral, as shall be
necessary to cause such Benefitted Lender to share the excess payment or
benefits of such collateral ratably with each of the Lenders; provided, however,
                                                              --------  -------
that if all or any portion of such excess payment or benefits is thereafter
recovered from such Benefitted Lender, such purchase shall be rescinded, and the
purchase price and benefits returned, to the extent of such recovery, but
without interest.

          (b)  In addition to any rights and remedies of the Lenders provided by
law, each Lender shall have the right, without prior notice to the Borrower, any
such notice being expressly waived by the Borrower to the extent permitted by
applicable law, upon any amount becoming due and payable by the Borrower
hereunder (whether at the stated maturity, by acceleration or otherwise), to set
off and appropriate and apply against such amount any and all deposits (general
or special, time or demand, provisional or final), in any currency, and any
other credits, indebtedness or claims, in any currency, in each case whether
direct or indirect, absolute or contingent, matured or unmatured, at any time
held or owing by such Lender or any branch or agency thereof to or for the
credit or the account of the Borrower, as the case may be.  Each Lender agrees
promptly to notify the Borrower and the Administrative Agent after any such
setoff and application made by such Lender, provided that the failure to give
                                            --------
such notice shall not affect the validity of such setoff and application.

          10.8  Counterparts.  This Agreement may be executed by one or more of
                ------------
the parties to this Agreement on any number of separate counterparts, and all of
said counterparts taken together shall be deemed to constitute one and the same
instrument. Delivery of an executed signature page of this Agreement by
facsimile transmission shall be effective as delivery of a manually executed
counterpart hereof. A set of the copies of this Agreement signed by all the
parties shall be lodged with the Borrower and the Administrative Agent.

          10.9  Severability.  Any provision of this Agreement that is
                ------------
prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction,
be ineffective to the extent of such prohibition or unenforceability without
invalidating the remaining provisions hereof, and any such prohibition or
unenforceability in any jurisdiction shall not invalidate or render
unenforceable such provision in any other jurisdiction.
<PAGE>

          10.10  Integration.  This Agreement and the other Loan Documents
                 -----------
represent the entire agreement of the Borrower, the Administrative Agent and the
Lenders with respect to the subject matter hereof and thereof, and there are no
promises, undertakings, representations or warranties by the Administrative
Agent or any Lender relative to subject matter hereof not expressly set forth or
referred to herein or in the other Loan Documents.

          10.11  GOVERNING LAW.  THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS
                 -------------
OF THE PARTIES UNDER THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND
INTERPRETED IN ACCORDANCE WITH, THE LAW OF THE STATE OF NEW YORK.

          10.12  Submission To Jurisdiction; Waivers. The Borrower hereby
                 -----------------------------------
irrevocably and unconditionally:

          (a)  submits for itself and its property in any legal action or
     proceeding relating to this Agreement and the other Loan Documents to which
     it is a party, or for recognition and enforcement of any judgment in
     respect thereof, to the non-exclusive general jurisdiction of the courts of
     the State of New York, the courts of the United States for the Southern
     District of New York, and appellate courts from any thereof;

          (b)  consents that any such action or proceeding may be brought in
     such courts and waives any objection that it may now or hereafter have to
     the venue of any such action or proceeding in any such court or that such
     action or proceeding was brought in an inconvenient court and agrees not to
     plead or claim the same;

          (c)  agrees that service of process in any such action or proceeding
     may be effected by mailing a copy thereof by registered or certified mail
     (or any substantially similar form of mail), postage prepaid, to the
     Borrower, as the case may be at its address set forth in Section 10.2 or at
     such other address of which the Administrative Agent shall have been
     notified pursuant thereto;

          (d)  agrees that nothing herein shall affect the right to effect
     service of process in any other manner permitted by law or shall limit the
     right to sue in any other jurisdiction; and

          (e)  waives, to the maximum extent not prohibited by law, any right it
     may have to claim or recover in any legal action or proceeding referred to
     in this Section any special, exemplary, punitive or consequential damages.

          10.13  Acknowledgements.  The Borrower hereby acknowledges that:

          (a)  it has been advised by counsel in the negotiation, execution and
     delivery of this Agreement and the other Loan Documents;
<PAGE>

          (b)  neither the Administrative Agent nor any Lender has any fiduciary
     relationship with or duty to the Borrower arising out of or in connection
     with this Agreement or any of the other Loan Documents, and the
     relationship between Administrative Agent and Lenders, on one hand, and the
     Borrower, on the other hand, in connection herewith or therewith is solely
     that of debtor and creditor; and

          (c)  no joint venture is created hereby or by the other Loan Documents
     or otherwise exists by virtue of the transactions contemplated hereby among
     the Lenders or among the Borrower and the Lenders.

          10.14  Releases of Guarantees and Liens.  (a)  Notwithstanding
                 --------------------------------
anything to the contrary contained herein or in any other Loan Document, the
Administrative Agent is hereby irrevocably authorized by each Lender (without
requirement of notice to or consent of any Lender except as expressly required
by Section 10.1) to take any action requested by the Borrower having the effect
of releasing any Collateral or guarantee obligations (i) to the extent necessary
to permit consummation of any transaction not prohibited by any Loan Document or
that has been consented to in accordance with Section 10.1 or (ii) under the
circumstances described in paragraph (b) below.

other obligations under the Loan Documents (other than obligations under or in
respect of Hedge Agreements) shall have been paid in full, the Revolving
Commitments have been terminated and no Letters of Credit shall be outstanding,
the Collateral shall be released from the Liens created by the Security
Documents, and the Security Documents and all obligations (other than those
expressly stated to survive such termination) of the Administrative Agent and
each Loan Party under the Security Documents shall terminate, all without
delivery of any instrument or performance of any act by any Person.

          10.15  Confidentiality.  Each of the Administrative Agent and each
                 ---------------
