EXCEED THE LICENSE FEES AND/OR ROYALTIES PAID BY UMC TO NUMERICAL TECHNOLOGIES
UNDER THIS AGREEMENT IN THE 24 MONTHS PRECEDING THE EVENT UPON WHICH LIABILITY
IS ALLEGED. NOTWITHSTANDING THE FOREGOING, NUMERICAL TECHNOLOGIES' LIABILITY
UNDER THIS AGREEMENT FOR DAMAGES FOR PATENT INFRINGEMENT (INCLUDING
INDEMNIFICATION AMOUNTS UNDER SECTION 9) WILL NOT, IN ANY EVENT, EXCEED * TIMES
(* X) THE AMOUNT OF THE LICENSE FEES AND ROYALTIES PAID BY UMC TO NUMERICAL
TECHNOLOGIES UNDER THIS AGREEMENT.

9.  Indemnification for Infringement.  Numerical Technologies shall, at its
    --------------------------------
expense, defend or settle any suit or proceeding brought against UMC to the
extent that it is based on a claim that the PSM Technology or PSM Software used
within the scope hereunder constitutes the misappropriation of a trade secret or
infringement of a copyright or patent right of any third party and shall pay any
final judgments awarded or settlements entered into except in the case of patent
infringement, with respect to which Numerical Technologies will not pay any
amount in excess of the limitation of liability set forth in Section 8.3.  The
foregoing defense and indemnification is contingent upon UMC giving prompt
written notice to Numerical Technologies of any such claim, action or proceeding
of infringement and giving Numerical Technologies the authority to proceed as
contemplated herein.  Numerical Technologies will have the exclusive right to
defend any such claim, action or allegation and make settlements thereof at its
own discretion, and UMC may not settle or compromise such claim, action or
allegation, except with prior written consent of Numerical Technologies, except
for claims of patent infringement, in which UMC shall have the right to jointly
participate in such defense and/or settlement.  UMC shall give such assistance
and information as Numerical Technologies may reasonably require to settle or
oppose such claims.  In the event any such infringement, claim, action or
allegation is brought or threatened, Numerical Technologies may, at its sole
option and expense:

(a) procure for UMC the right to continue Use of the PSM Technology or PSM
Software, or infringing part thereof; or

(b )modify or amend the PSM Technology or PSM Software or infringing part
thereof, or replace the PSM Technology or PSM Software or infringing part
thereof with other software having substantially the same or better
capabilities; or, if neither of the foregoing is commercially practicable,

(c) terminate UMC's license for the PSM Software and refund to UMC all license
fees paid by UMC for the PSM Software, upon which time  Numerical Technologies
and UMC will be released from any further obligation to the other under this
Agreement, except for the obligations of indemnification provided for above and
such other obligations that survive termination.

Notwithstanding the above, in the event Numerical Technologies decides to
terminate UMC's license pursuant to this subsection for patent infringement (c),
UMC may choose to continue being licensed under this Agreement but any
indemnification obligations of Numerical Technologies shall terminate for patent
infringement arising out of UMC's use after the date of notice of termination
and refund by NTI.

The foregoing obligations shall not apply to the extent the infringement arises
as a result of modifications to the PSM Technology or PSM Software not provided
by Numerical Technologies.

THE FOREGOING STATES THE SOLE REMEDY AND THE ENTIRE LIABILITY OF EITHER PARTY
WITH RESPECT TO INFRINGEMENT OF ANY PATENT, COPYRIGHT, TRADE SECRET OR OTHER
PROPRIETARY RIGHT OF A THIRD PARTY.

     Loans.  OpCo may make only one borrowing under the Term Loan Commitment
     which shall be on the

                                      36

     Funding Date.  Any amount borrowed under this Section 2.1(a)(i) and
     subsequently repaid or prepaid may not be reborrowed. Subject to Sections
     2.10(a), 2.11(a) and 2.12, all amounts owed hereunder with respect to the
     Term Loans shall be paid in full no later than the Term Loan Maturity Date.
     Each Lender's Term Loan Commitment shall terminate immediately and without
     further action on the Funding Date after giving effect to the funding of
     such Lender's Term Loan Commitment.

               (ii)   Delayed Draw Term Loans. During the Delayed Draw Term Loan
                      -----------------------
     Commitment Period, subject to the terms and conditions hereof, each Lender
     holding a Delayed Draw Term Loan Commitment severally agrees to make
     Delayed Draw Term Loans to OpCo in the aggregate amount up to but not
     exceeding such Lender's Delayed Draw Term Loan Commitment; provided that
                                                                --------
     after giving effect to the making of any Delayed Draw Term Loans in no
     event shall (x) the Total Utilization of the Delayed Draw Term Loan
     Commitments exceed the Delayed Draw Term Loan Commitments then in effect
     and (y) the Total Utilization Exposure exceed the Borrowing Base as set
     forth in a Borrowing Base Certificate delivered pursuant to Section 5.1(e)
     in connection with the making of such Loans; provided, however, that if, on
                                                  --------  -------
     the date which is twelve (12) months following the Closing Date, any
     portion of the Delayed Draw Term Loan Commitment is not permitted to be
     drawn as a result of the application of clause (y) of the immediately
     preceding proviso, OpCo shall be entitled (but not obligated) to borrow the
     portion of the Delayed Draw Term Loans which is required to be drawn on
     such date in accordance with the last sentence of this paragraph, so long
     as such amount (the "Escrowed Funds") is held in a pledged account included
     in the Collateral in which the Collateral Agent for the benefit of the
     Secured Parties has a First Priority Lien on such terms and conditions
     satisfactory to Administrative Agent until such time as OpCo demonstrates
     compliance with such proviso in a Borrowing Certificate delivered pursuant
     to Section 5.1(e).  OpCo may make one or more drawings on the Delayed Draw
     Term Loan Commitments during the Delayed Draw Term Loan Commitment Period.
     Any amounts borrowed under this Section 2.1(a)(ii) and subsequently repaid
     or prepaid may not be reborrowed.  Subject to Sections 2.10(a), 2.11(a) and
     2.12, all amounts owed hereunder with respect to the Delayed Draw Term
     Loans shall be paid in full no later than the Delayed Draw Term Loan
     Maturity Date.  Each Lender's Delayed Draw Term Loan Commitment shall
     terminate immediately and without further action upon the funding in full
     of such Lender's Delayed Draw Term Loan Commitment.  The Delayed Draw Term
     Loan Commitment shall expire immediately and without further action on a
     date occurring twelve (12) months after the Closing Date, if Delayed Draw
     Term Loans in an amount equal to the aggregate Delayed Draw Term Loan
     Commitments are not made on or before such date.

               (iii)  Revolving Loans.  During the Revolving Loan Commitment
                      ---------------
     Period, subject to the terms and conditions hereof, each Lender holding a
     Revolving Loan Commitment severally agrees to make Revolving Loans to OpCo
     in the aggregate amount up to but not exceeding such Lender's Revolving
     Loan

                                      37
<PAGE>

     Commitment as of the Closing Date; provided that after giving effect to the
                                        --------
     making of any Revolving Loans in no event shall (x) the Total Utilization
     of Revolving Loan Commitments exceed the lesser of (i) the Revolving Loan
     Commitments then in effect and (ii) to the extent required in order to
     comply with the terms of the Senior Notes, 85% of Net Accounts Receivable
     (the "A/R Sublimit") determined as of the most recent A/R Sublimit
     Measurement Date or (y) the Total Utilization Exposure exceed the Borrowing
     Base as set forth in a Borrowing Base Certificate delivered pursuant to
     Section 5.1(e) in connection with the making of such Loans provided,
                                                                --------
     further that, notwithstanding the foregoing, the Company may make
     -------
     borrowings otherwise permitted under the Revolving Facility in excess of
     the A/R Sublimit to finance not greater than 20% of the costs of equipment
     and software located in Permitted IBX Facilities either owned by the
     Company or leased by the Company under a lease subject to a leasehold
     mortgage in favor of the Collateral Agent for the benefit of the Lenders
     providing such Purchase Money Loans ("Purchase Money Loans"); provided,
                                                                   --------
     that, any Purchase Money Loans made to the Company shall be secured solely
     by the assets purchased with the proceeds of such Loans.  Amounts borrowed
     pursuant to this Section 2.1(a)(iii) may be repaid and reborrowed during
     the Revolving Loan Commitment Period.  Subject to Sections 2.11 and 2.12,
     each Lender's Revolving Loan Commitment shall expire on the Revolving Loan
     Commitment Termination Date and all Revolving Loans and all other amounts
     owed hereunder with respect to the Revolving Loans and the Revolving Loan
     Commitments shall be paid in full no later than such date.  If as of any
     A/R Sublimit Measurement Date the A/R Sublimit exceeds the amount
     outstanding under the Revolving Loans (net of any amounts outstanding under
     the Purchase Money Loans), a portion of the Purchase Money Loans equal to
     the amount of such excess shall be automatically deemed converted to
     Revolving Loans outstanding to OpCo and shall, on and after such date be
     treated for all purposes as such Revolving Loans and not as Purchase Money
     Loans.

               (iv)   Incremental Facilities. To the extent not prohibited under
                      ----------------------
     the Senior Notes, OpCo or Company may by written notice to Syndication
     Agent elect to request (A) prior to the Revolving Loan Commitment
     Termination Date, an increase in the existing Revolving Loan Commitments
     (any such increase, the "New Revolving Loan Commitments") and/or (B) the
     establishment of one or more new term loan commitments (the "New Term Loan
     Commitments"), by an amount not in excess of $100,000,000 in the aggregate
     and not less than $5,000,000 individually (or such lesser amount which
     shall be approved by Syndication Agent or such lesser amount that shall
     constitute the difference between $100,000,000 and all such New Revolving
     Loan Commitments and New Term Loan Commitments), and integral multiples of
     $5,000,000 in excess of that amount. Each such notice shall specify (A) the
     date (each, an "Increased Amount Date") on which Company proposes that the
     New Revolving Loan Commitment or the New Term Loan Commitment, as
     applicable, shall be effective and that Loans be made pursuant to the New
     Term Loan Commitments ("New Term Loans"), which shall be a date not less
     than 10 Business Days after the date on which such notice is delivered to
     Syndication Agent and (B) the identity of each

                                       38

     Loan Lender", as applicable) to whom OpCo or Company, as applicable,
     proposes any portion of such New Revolving Loan Commitment or New Term Loan
     Commitment, as applicable, be allocated and the amounts of such
     allocations; provided that any Lender approached to provide all or a
                  --------
     portion of the New Revolving Loan Commitment or New Term Loan Commitment
     may elect or decline, in its sole discretion, to provide a New Revolving
     Loan Commitment or a New Term Loan Commitment. Such New Revolving Loan
     Commitment or New Term Loan Commitment shall become effective, as of such
     Increased Amount Date; provided that (1) no Default or Event of Default
                            --------
     shall exist on such Increased Amount Date before or after giving effect to
     such New Revolving Loan Commitment or New Term Loan Commitment, as
     applicable; (2) both before and after giving effect to the making of any
     Series of New Term Loans each of the conditions set forth in Section 3.2
     shall be satisfied; (3) the New Revolving Loan Commitment or New Term Loan
     Commitment, as applicable, shall be effected pursuant to one or more
     Joinder Agreements executed and delivered to Administrative Agent, and each
     shall be recorded in the Register, each of which shall be subject to the
     requirements set forth in Section 2.19(c); (4) the applicable Borrower
     shall make any payments required pursuant to Section 2.17(c) in connection
     with the New Revolving Loan Commitment, and (5) the applicable Borrower
     shall deliver or cause to be delivered any legal opinions, Notes and/or
     other documents reasonably requested by Administrative Agent in connection
     with any such transaction. Any New Term Loans made shall be designated a
     separate series (each, a "Series") of New Term Loans for all purposes of
     this Agreement.

     On any Increased Amount Date on which New Revolving Loan Commitments are
effected, subject to the satisfaction of the foregoing terms and conditions, (a)
each of the Lenders holding Revolving Loans shall assign to each of the New
Revolving Loan Lenders, and each of the New Revolving Loan Lenders shall
purchase from each of the  Lenders holding Revolving Loans, at the principal
amount thereof, such interests in the Revolving Loans outstanding on such
Increased Amount Date as shall be necessary in order that, after giving effect
to all such assignments and purchases, such Revolving Loans will be held by
existing Lenders and New Revolving Loan Lenders ratably in accordance with their
Revolving Loan Commitments after giving effect to the addition of such New
Revolving Loan Commitment to the Revolving Commitments, (b) each New Revolving
Commitment shall be deemed for all purposes a Revolving Commitment and each Loan
made thereunder (a "New Revolving Loan") shall be deemed, for all purposes, a
Revolving Loan and (c) each New Revolving Loan Lender shall become a Lender with
respect to the Revolving Commitments and all matters relating thereto.

     On any Increased Amount Date on which any New Term Loan Commitments of any
Series are effective, subject to the satisfaction of the foregoing terms and
conditions, (i) each New Term Loan Lender of any Series shall make a New Term
Loan to Company to the extent required to be made under such New Term Loan
Commitment on such date, and (ii) each New Term Loan Lender of any Series shall
become a Lender hereunder with respect to the New Term Loan Commitment of such
Series and the New Term Loans of such Series made pursuant thereto.

     The Syndication Agent shall notify the Lenders promptly in writing upon
receipt of the applicable Borrower's notice of each Increased Amount Date and in
respect thereof the New Revolving Loan Commitment and the New Revolving Loan
Lenders or the Series of New Term Loan Commitments and the New Term Loan Lenders
of such Series, as applicable, and, in the case of each notice to any Lender
with a Revolving Loans Commitment, the respective interests in such Lender's
Revolving Loans subject to the assignments contemplated by this section.

     The terms and provisions of the New Term Loans of any Series and New Term
Loan Commitments of any Series shall be, except as otherwise set forth herein or
in the Joinder Agreement, identical to the Term Loans and in any event (i) the
amortization of all New Term Loans of any Series, shall occur no sooner than the
proportional amortization of the Term Loans, (ii) the final maturity of all New
Term Loans of any Series shall be no earlier than the Term Loan Maturity Date,
(iii) the rate of interest applicable to New Term Loans of any Series shall be
determined by the applicable Borrower and applicable new Lenders and shall be
set forth in each applicable Joinder Agreement and any New Term Loans made to
the Company shall, to the extent necessary to comply with the Senior Notes,
otherwise be made on the same basis as the Purchase Money Loans.  Each Joinder
Agreement may, without the consent of any other Lenders, effect such amendments
to this Agreement and the other Credit Documents as may be necessary or
appropriate, in the opinion of the Syndication Agent and the Administrative
Agent, to effect the provision of this Section 2.1(a)(iv).

     Administrative Agent a fully executed and delivered Closing Date
     Certificate and a Funding Notice on the Closing Date. Promptly upon receipt
     by Administrative Agent of such certificate, Administrative Agent shall
     notify each Lender in writing of the proposed borrowing.

               (iv)   Whenever a Borrower desires that Lenders make Loans, the
     applicable Borrower shall deliver to Administrative Agent telephonic
     notice, followed by a fully executed and delivered Funding Notice no later
     than 10:00 a.m. (New York City time) at least three (3) Business Days in
     advance of the proposed Credit Date in the case of a Eurodollar Rate Loan,

     irrevocable on and after the related Interest Rate Determination Date, and
     the applicable Borrower shall be bound to make a borrowing in accordance
     therewith.

               (v)  Notice of receipt of each Funding Notice in respect of
     Loans, together with the amount of each Lender's Pro Rata Share thereof, if
     any, together with the applicable interest rate, shall be provided by

     applicable Credit Date by wire transfer of same day funds in Dollars, at
     the Administrative Agent's Principal Office.  Except as provided herein,

     2.2  Issuance of Letters of Credit and Purchase of Participations Therein.

          (a) Letters of Credit.  During the Revolving Loan Commitment Period,
              -----------------
subject to the terms and conditions hereof,  Issuing Bank agrees to issue
Letters of Credit for the account of OpCo in the aggregate amount up to but not
exceeding the Letter of Credit Sublimit; provided, (i) each Letter of Credit
                                         --------
shall be denominated in Dollars; (ii) the stated amount of each Letter of Credit
shall not be less than $500,000 or such lesser amount as is acceptable to
Issuing Bank; (iii) after giving effect to such issuance, in no event shall the
Total Utilization of Revolving Loan Commitments exceed the Revolving Loan
Commitments then in effect; (iv) after giving effect to such issuance, to the
extent required in order to comply with the terms of the Senior Notes, the Total
Utilization of Revolving Loan Commitments, less the aggregate amount outstanding
under any Purchase Money Loans, shall not exceed the A/R Sublimit; (v) after
giving effect to such issuance, in no event shall the Letter of Credit Usage
exceed the Letter of Credit Sublimit then in effect; (vi) in no event shall any
standby Letter of Credit have an expiration date later than the earlier of  the
Revolving Loan Commitment Termination Date and  the date which is one year from
the date of issuance of such standby Letter of Credit; and (vii) in no event
shall any commercial Letter of Credit (x) have an expiration date later than the
earlier of (1) the Revolving Loan Commitment Termination Date and (2) the date
which is 180 days from the date of issuance of such commercial Letter of Credit
or (y) be issued if such commercial Letter of Credit is otherwise unacceptable
to the Issuing Bank in its reasonable discretion.  Subject to the foregoing,
Issuing Bank may agree that a standby Letter of Credit will automatically be
extended for one or more successive periods not to exceed one year each, unless
Issuing Bank elects not to extend for any such additional period; provided,
                                                                  --------
Issuing Bank shall not extend any such Letter of Credit if it has received
written notice that an Event of Default has occurred and is continuing at the
time Issuing Bank must elect to allow such extension; provided
                                                      --------

                                       41
<PAGE>

further, in the event a Funding Default exists, Issuing Bank shall not be
-------
required to issue any Letter of Credit unless Issuing Bank has entered into
arrangements satisfactory to it and OpCo to eliminate Issuing Bank's risk with
respect to the participation in Letters of Credit of the Defaulting Lender,
including by cash collateralizing such Defaulting Lender's Pro Rata Share of the
Letter of Credit Usage.

          (b) Notice of Issuance.  Whenever OpCo desires the issuance of a
              ------------------
Letter of Credit, it shall deliver to Administrative Agent and Issuing Bank an
Issuance Notice no later than 12:00 p.m. (New York City time) at least three (3)
Business Days such shorter period as may be agreed to by Issuing Bank in any
particular instance, in advance of the proposed date of issuance.  Upon
satisfaction or waiver of the conditions set forth in Section 3.2, Issuing Bank
shall issue the requested Letter of Credit only in accordance with Issuing
Bank's standard operating procedures.  Upon the issuance of any Letter of Credit
or amendment or modification to a Letter of Credit, Issuing Bank shall promptly
notify each Lender in writing of such issuance, which notice shall be
accompanied by a copy of such Letter of Credit or amendment or modification to a
Letter of Credit  and the amount of such Lender's respective participation in
such Letter of Credit pursuant to Section 2.2(e).  Within fifteen (15) days
after the end of each month ending after the Closing Date, so long as any Letter
of Credit shall have been outstanding during such month, Issuing Bank shall
deliver to each Lender a report setting forth for such month the daily aggregate
amount available to be drawn under the Letters of Credit that were outstanding
during such month.

          (c) Responsibility of Issuing Bank With Respect to Requests for
              -----------------------------------------------------------
Drawings and Payments.  In determining whether to honor any drawing under any
---------------------
Letter of Credit by the beneficiary thereof, Issuing Bank shall be responsible
only to examine the documents delivered under such Letter of Credit with
reasonable care so as to ascertain whether they appear on their face to be in
accordance with the terms and conditions of such Letter of Credit.  As between
OpCo and Issuing Bank, OpCo assumes all risks of the acts and omissions of, or
misuse of the Letters of Credit issued by Issuing Bank, by the respective
beneficiaries of such Letters of Credit.  In furtherance and not in limitation
of the foregoing, Issuing Bank shall not be responsible for:  the form,
validity, sufficiency, accuracy, genuineness or legal effect of any document
submitted by any party in connection with the application for and issuance of
any such Letter of Credit, even if it should in fact prove to be in any or all
respects invalid, insufficient, inaccurate, fraudulent or forged;  the validity
or sufficiency of any instrument transferring or assigning or purporting to
transfer or assign any such Letter of Credit or the rights or benefits
thereunder or proceeds thereof, in whole or in part, which may prove to be
invalid or ineffective for any reason;  failure of the beneficiary of any such
Letter of Credit to comply fully with any conditions required in order to draw
upon such Letter of Credit;  errors, omissions, interruptions or delays in
transmission or delivery of any messages, by mail, cable, telegraph, telex or
otherwise, whether or not they be in cipher;  errors in interpretation of
technical terms;  any loss or delay in the transmission or otherwise of any
document required in order to make a drawing under any such Letter of Credit or
of the proceeds thereof;  the misapplication by the beneficiary of any such
Letter of Credit of the proceeds of any drawing under such Letter of Credit; or
any consequences arising from causes beyond the control of Issuing Bank,
including any Governmental Acts; none of the above shall affect or impair, or
prevent the vesting of, any of Issuing Bank's rights or powers hereunder.
Without limiting the foregoing and in furtherance thereof, any action taken or
omitted by Issuing Bank under or in connection with the Letters of

                                       42
<PAGE>

Credit or any documents and certificates delivered thereunder, if taken or
omitted in good faith, shall not put Issuing Bank under any resulting liability
to OpCo. Notwithstanding anything to the contrary contained in this Section
2.2(c), OpCo shall retain any and all rights it may have against Issuing Bank
for any liability arising solely out of the gross negligence or willful
misconduct of Issuing Bank.

          (d) Reimbursement by the applicable Borrower of Amounts Drawn or Paid
              -----------------------------------------------------------------
Under Letters of Credit.  In the event Issuing Bank has determined to honor a
-----------------------
drawing under a Letter of Credit, it shall immediately notify OpCo and
Administrative Agent, and OpCo shall reimburse Issuing Bank on or before the
Business Day immediately following the date on which such drawing is honored
(the "Reimbursement Date") in an amount in Dollars and in same day funds equal
to the amount of such honored drawing; provided, anything contained herein to
                                       --------
the contrary notwithstanding,  (i) unless OpCo shall have notified
Administrative Agent and Issuing Bank prior to 10:00 a.m. (New York City time)
on the date such drawing is honored that OpCo intends to reimburse Issuing Bank
for the amount of such honored drawing with funds other than the proceeds of
Revolving Loans, OpCo shall be deemed to have given a timely Funding Notice to
Administrative Agent requesting Lenders to make Revolving Loans that are Base
Rate Loans on the Reimbursement Date in an amount in Dollars equal to the amount
of such honored drawing,  (and the Administrative Agent shall give prompt
written notice thereof and of the amount of its respective Pro Rata Share of the
amount of such honored drawing to each of the Lenders) and  (ii) subject to
satisfaction or waiver of the conditions specified in Section 3.2, Lenders
shall, on the Reimbursement Date, make Revolving Loans that are Base Rate Loans
in the amount of such honored drawing, the proceeds of which shall be applied
directly by Administrative Agent to reimburse Issuing Bank for the amount of
such honored drawing; and provided further, if for any reason proceeds of
                          -------- -------
Revolving Loans are not received by Issuing Bank on the Reimbursement Date in an
amount equal to the amount of such honored drawing, OpCo shall reimburse Issuing
Bank, on demand, in an amount in same day funds equal to the excess of the
amount of such honored drawing over the aggregate amount of such Revolving
Loans, if any, which are so received.  Nothing in this Section 2.2(d) shall be
deemed to relieve any Lender from its obligation to make Revolving Loans on the
terms and conditions set forth herein, and OpCo shall retain any and all rights
it may have against any Lender resulting from the failure of such Lender to make
such Revolving Loans under this Section 2.2(d).

          (e) Lenders' Purchase of Participations in Letters of Credit.
              --------------------------------------------------------
Immediately upon the issuance of each Letter of Credit, each Lender having a
Revolving Loan Commitment shall be deemed to have purchased, and hereby agrees
to irrevocably purchase, from Issuing Bank a participation in such Letter of
Credit and any drawings honored thereunder in an amount equal to such Lender's
Pro Rata Share (with respect to the Revolving Loan Commitments) of the maximum
amount which is or at any time may become available to be drawn thereunder.  In
the event that OpCo shall fail for any reason to reimburse Issuing Bank as
provided in Section 2.2(d), Issuing Bank shall promptly notify each Lender in
writing of the unreimbursed amount of such honored drawing and of such Lender's
respective participation therein based on such Lender's Pro Rata Share of the
Revolving Loan Commitments.  Each Lender shall make available to Issuing Bank an
amount equal to its respective participation, in Dollars and in same day funds,
at the office of Issuing Bank specified in such notice, not later than 12:00
p.m. (New York City time) on the first business day (under the laws of the
jurisdiction in which such office of Issuing Bank is located) after the date
notified by Issuing Bank.  In the event that any Lender

                                       43
<PAGE>

fails to make available to Issuing Bank on such business day the amount of such
Lender's participation in such Letter of Credit as provided in this Section
2.2(e), Issuing Bank shall be entitled to recover such amount on demand from
such Lender together with interest thereon for three (3) Business Days at the
rate customarily used by Issuing Bank for the correction of errors among banks
and thereafter at the Base Rate. Nothing in this Section 2.2(e) shall be deemed
to prejudice the right of any Lender to recover from Issuing Bank any amounts
made available by such Lender to Issuing Bank pursuant to this Section 2.2(e) in
the event that it is determined that the payment with respect to a Letter of
Credit in respect of which payment was made by such Lender constituted gross
negligence or willful misconduct on the part of Issuing Bank. In the event
Issuing Bank shall have been reimbursed by other Lenders pursuant to this
Section 2.2(e) for all or any portion of any drawing honored by Issuing Bank
under a Letter of Credit, such Issuing Bank shall distribute to each Lender
which has paid all amounts payable by it under this Section 2.2(e) with respect
to such honored drawing such Lender's Pro Rata Share of all payments
subsequently received by Issuing Bank from OpCo in reimbursement of such honored
drawing promptly when such payments are received. Any such distribution shall be
made to a Lender at its primary address set forth below its name on Appendix B
or at such other address as such Lender may request.

          (f) Obligations Absolute.  The obligation of OpCo to reimburse Issuing
              --------------------
Bank for drawings honored under the Letters of Credit issued by it and to repay
any Revolving Loans made by Lenders pursuant to Section 2.2(d) and the
obligations of Lenders under Section 2.2(e) shall be unconditional and
irrevocable and shall be paid strictly in accordance with the terms hereof under
all circumstances including any of the following circumstances: any lack of
validity or enforceability of any Letter of Credit; the existence of any claim,
setoff, defense or other right which OpCo or any Lender may have at any time
against a beneficiary or any transferee of any Letter of Credit (or any Persons
for whom any such transferee may be acting), Issuing Bank, Lender or any other
Person or, in the case of a Lender, against OpCo, whether in connection
herewith, the transactions contemplated herein or with any unrelated transaction
(including any underlying transaction between OpCo or one of its Subsidiaries
and the beneficiary for which any Letter of Credit was procured); any draft or
other document presented under any Letter of Credit proving to be forged,
fraudulent, invalid or insufficient in any respect or any statement therein
being untrue or inaccurate in any respect; payment by Issuing Bank under any
Letter of Credit against presentation of a draft or other document which does
not substantially comply with the terms of such Letter of Credit; any adverse
change in the business, operations, properties, assets, condition (financial or
otherwise) or prospects of OpCo or any of its Subsidiaries; any breach hereof or
of any other Credit Document by any party thereto; any other circumstance or
happening whatsoever, whether or not similar to any of the foregoing; or the
fact that an Event of Default or a Default shall have occurred and be
continuing; provided, in each case, that payment by Issuing Bank under the
            --------
applicable Letter of Credit shall not have constituted gross negligence or
willful misconduct of Issuing Bank under the circumstances in question.

          (g) Indemnification.  Without duplication of any obligation of OpCo
              ---------------
under Section 10.2 or 10.3, in addition to amounts payable as provided herein,
OpCo agrees to protect, indemnify, pay and save harmless Issuing Bank and the
other Agents and Lenders from and against any and all claims, demands,
liabilities, damages, losses, costs, charges and expenses (including reasonable
fees, expenses and disbursements of counsel and allocated costs of internal

                                       44
<PAGE>

counsel) which Issuing Bank may incur or be subject to as a consequence, direct
or indirect, of the issuance of any Letter of Credit by Issuing Bank, the
wrongful dishonor by Issuing Bank of a proper demand for payment made under any
Letter of Credit issued by it, or the failure of Issuing Bank to honor a drawing
under any such Letter of Credit as a result of any Governmental Act, in each
case, other than as a result of the gross negligence or willful misconduct of
Issuing Bank.

     2.3  Pro Rata Shares; Availability of Funds.

          (a) Pro Rata Shares.  All Loans shall be made, and all participations
              ---------------
purchased, by Lenders concurrently and proportionately to their respective Pro
Rata Shares, it being understood that no Lender shall be responsible for any
default by any other Lender in such other Lender's obligation to make a Loan
requested hereunder or purchase a participation required hereby nor shall any
Commitment of any Lender be increased or decreased as a result of a default by
any other Lender in such other Lender's obligation to make a Loan requested
hereunder or purchase a participation required hereby.

          (b) Availability of Funds.  Unless Administrative Agent shall have
              ---------------------
been notified by any Lender prior to the applicable Credit Date that such Lender
does not intend to make available to Administrative Agent the amount of such
Lender's Loan requested on such Credit Date, Administrative Agent may assume
that such Lender has made such amount available to Administrative Agent on such
Credit Date and Administrative Agent may, in its sole discretion, but shall not
be obligated to, make available to the applicable Borrower a corresponding
amount on such Credit Date.  If such corresponding amount is not in fact made
available to Administrative Agent by such Lender, Administrative Agent shall be
entitled to recover such corresponding amount on demand from such Lender
together with interest thereon, for each day from such Credit Date until the
date such amount is paid to Administrative Agent, at the customary rate set by
Administrative Agent for the correction of errors among banks for three (3)
Business Days and thereafter at the Base Rate.  If such Lender does not pay such
corresponding amount forthwith upon Administrative Agent's demand therefor,
Administrative Agent shall promptly notify the applicable Borrower and the
applicable Borrower shall immediately pay such corresponding amount to
Administrative Agent together with interest thereon, for each day from such
Credit Date until the date such amount is paid to Administrative Agent, at the
rate payable hereunder for Base Rate Loans for such Class of Loans.  Nothing in
this Section 2.3(b) shall be deemed to relieve any Lender from its obligation to
fulfill its Commitments hereunder or to prejudice any rights that the applicable
Borrower may have against any Lender as a result of any default by such Lender
hereunder.

     2.4  Use of Proceeds.  The proceeds of the Loans shall be used (i) to
provide financing for the cost of design, development, acquisition,
construction, installation, improvement, transportation and/or integration of
equipment, inventory or facility assets, inventory or network assets and of
leasing and acquiring of real property, and (ii) for working capital and other
general corporate purposes of the Company and its Domestic Subsidiaries,
including Permitted Acquisitions; provided that, Purchase Money Loans may only
                                  --------
be used to finance not more than 20% of the costs of equipment and software
located in Permitted IBX Facilities either owned by the Company or leased by the
Company under a lease subject to a leasehold mortgage in favor of the Collateral
Agent.  No portion of the proceeds of any Credit Extension shall be used by
Company or any of its Subsidiaries in any manner that might cause

                                       45
<PAGE>

such Credit Extension or the application of such proceeds to violate Regulation
T, Regulation U or Regulation X of the Board of Governors of the Federal Reserve
System or any other regulation thereof or to violate the Exchange Act.

     2.5  Evidence of Debt; Register; Lenders' Books and Records; Notes.

          (a) Lenders' Evidence of Debt.  Each Lender shall maintain on its
              -------------------------
internal records an account or accounts evidencing the Indebtedness of each
Borrower to such Lender, including the amounts of the Loans made by it and each
repayment and prepayment in respect thereof.  Any such recordation shall be
conclusive and binding on the Borrowers, absent manifest error; provided,
                                                                --------
failure to make any such recordation, or any error in such recordation, shall
not affect any Lender's Commitments or either Borrower's Obligations in respect
of any applicable Loans; and provided further, in the event of any inconsistency
                             -------- -------
between the Register and any Lender's records, the recordations in the Register
shall govern.

          (b) Register.  Administrative Agent shall maintain at its Principal
              --------
Office a register for the recordation of the names and addresses of Lenders and
the Commitments and Loans of each Lender from time to time (the "Register").
The Register shall be available for inspection by either Borrower or any Lender
at any reasonable time and from time to time upon reasonable prior notice.
Administrative Agent shall record in the Register the Commitments and the Loans,
and each repayment or prepayment in respect of the principal amount of the
Loans, and any such recordation shall be conclusive and binding on the
applicable Borrower and each Lender, absent manifest error; provided, failure to
                                                            --------
make any such recordation, or any error in such recordation, shall not affect
any Lender's Commitments or either Borrower's Obligations in respect of any
Loan.  Each Borrower hereby designates the Administrative Agent to serve as such
Borrower's agent solely for purposes of maintaining the Register as provided in
this Section 2.5, and each Borrower hereby agrees that, to the extent the
Administrative Agent serves in such capacity, the Administrative Agent and its
officers, directors, employees, agents and affiliates shall constitute
"Indemnitees."

          (c) Notes.  If so requested by any Lender by written notice to a
              -----
Borrower (with a copy to Administrative Agent) at least two (2) Business Days
prior to the Closing Date, or at any time thereafter, such Borrower shall
execute and deliver to such Lender (and/or, if applicable and if so specified in
such notice, to any Person who is an assignee of such Lender pursuant to Section
10.6) on the Closing Date (or, if such notice is delivered after the Closing
Date, promptly after such Borrower's receipt of such notice) a Note or Notes to
evidence such Lender's Loans.

     2.6  Interest on Loans.

          (a)  Except as otherwise set forth herein, each Loan shall bear
interest on the unpaid principal amount thereof from the date made through
repayment (whether by acceleration or otherwise) thereof as follows:

               (i)  if a Base Rate Loan, at the Base Rate plus the Applicable
                                                          ----
     Margin; or

                                       46
<PAGE>

              (ii) if a Eurodollar Rate Loan, at the Adjusted Eurodollar Rate
     plus the Applicable Margin.
     ----

          (b) The basis for determining the rate of interest with respect to any
Loan, and the Interest Period with respect to any Eurodollar Rate Loan, shall be
selected by the applicable Borrower and notified to Administrative Agent and
Lenders pursuant to the applicable Funding Notice or Conversion/Continuation
Notice, as the case may be; provided, the Loans initially shall be made and
                            --------
maintained as either Base Rate Loans or Eurodollar Rate Loans having an Interest
Period of no longer than one month until the date which is the earlier of (i)
the date which is 60 days following the Closing Date and (ii) the date that
Syndication Agent notifies the applicable Borrower that the primary syndication
of the Loans and Commitments has been completed, as determined by Syndication
Agent.  If on any day a Loan is outstanding with respect to which a Funding
Notice or Conversion/Continuation Notice has not been delivered to
Administrative Agent in accordance with the terms hereof specifying the
applicable basis for determining the rate of interest, then for that day such
Loan shall be a Base Rate Loan.

          (c) In connection with Eurodollar Rate Loans there shall be no more
than ten (10) Interest Periods outstanding at any time.  In the event a Borrower
fails to specify between a Base Rate Loan or a Eurodollar Rate Loan in the
applicable Funding Notice or Conversion/Continuation Notice, such Loan (if
outstanding as a Eurodollar Rate Loan) will be automatically converted into a
Base Rate Loan on the last day of the thencurrent Interest Period for such Loan
(or if outstanding as a Base Rate Loan will remain as, or (if not then
outstanding) will be made as, a Base Rate Loan).  In the event the applicable
Borrower fails to specify an Interest Period for any Eurodollar Rate Loan in the
applicable Funding Notice or Conversion/Continuation Notice, the applicable
Borrower shall be deemed to have selected an Interest Period of one month.  As
soon as practicable after 10:00 a.m. (New York City time) on each Interest Rate
Determination Date, Administrative Agent shall determine (which determination
shall, absent manifest error, be final, conclusive and binding upon all parties)
the interest rate that shall apply to the Eurodollar Rate Loans for which an
interest rate is then being determined for the applicable Interest Period and
shall promptly give notice thereof (in writing or by telephone confirmed in
writing) to the applicable Borrower and each Lender.

          (d) Interest payable pursuant to Section 2.6(a) shall be computed in
the case of Base Rate Loans on the basis of a 365day or 366day year, as the case
may be, and in the case of Eurodollar Rate Loans, on the basis of a 360day year,
in each case for the actual number of days elapsed in the period during which it
accrues.  In computing interest on any Loan, the date of the making of such Loan
or the first day of an Interest Period applicable to such Loan or, with respect
to a Base Rate Loan being converted from a Eurodollar Rate Loan, the date of
conversion of such Eurodollar Rate Loan to such Base Rate Loan, as the case may
be, shall be included, and the date of payment of such Loan or the expiration
date of an Interest Period applicable to such Loan or, with respect to a Base
Rate Loan being converted to a Eurodollar Rate Loan, the date of conversion of
such Base Rate Loan to such Eurodollar Rate Loan, as the case may be, shall be
excluded; provided, if a Loan is repaid on the same day on which it is made, one
          --------
day's interest shall be paid on that Loan.

          (e) Except as otherwise set forth herein, interest on each Loan shall
be payable in arrears (i) on each Interest Payment Date applicable to that Loan;
(ii) in the case of

                                       47
<PAGE>

any prepayment of that Loan, whether voluntary or mandatory, on the date of
prepayment (to the extent accrued on the amount being prepaid); and (iii) at
maturity, including final maturity; provided, however, with respect to any
                                    --------
voluntary prepayment of a Base Rate Loan, accrued interest shall instead be
payable on the applicable Interest Payment Date.

          (f) OpCo agrees to pay to Issuing Bank, with respect to drawings
honored under any Letter of Credit, interest on the amount paid by Issuing Bank
in respect of each such honored drawing from the date such drawing is honored to
but excluding the date such amount is reimbursed by or on behalf of OpCo at a
rate equal to, for the period from the date such drawing is honored to but
excluding the applicable Reimbursement Date, the rate of interest otherwise
payable hereunder with respect to Revolving Loans that are Base Rate Loans, and
thereafter, a rate which is 2% per annum in excess of the rate of interest
otherwise payable hereunder with respect to Revolving Loans that are Base Rate
Loans.

          (g) Interest payable pursuant to Section 2.6(f) shall be computed on
the basis of a 365/366day year for the actual number of days elapsed in the
period during which it accrues, and shall be payable on demand or, if no demand
is made, on the date on which the related drawing under a Letter of Credit is
reimbursed in full.  Promptly upon receipt by Issuing Bank of any payment of
interest pursuant to Section 2.6(f), Issuing Bank shall distribute to each
Lender, out of the interest received by Issuing Bank in respect of the period
from the date such drawing is honored to but excluding the date on which Issuing
Bank is reimbursed for the amount of such drawing (including any such
reimbursement out of the proceeds of any Revolving Loans), the amount that such
Lender would have been entitled to receive in respect of the letter of credit
fee that would have been payable in respect of such Letter of Credit for such
period if no drawing had been honored under such Letter of Credit.  In the event
Issuing Bank shall have been reimbursed by Lenders for all or any portion of
such honored drawing, Issuing Bank shall distribute to each Lender which has
paid all amounts payable by it under Section 2.2(e) with respect to such honored
drawing such Lender's Pro Rata Share of any interest received by Issuing Bank in
respect of that portion of such honored drawing so reimbursed by Lenders for the
period from the date on which Issuing Bank was so reimbursed by Lenders to but
excluding the date on which such portion of such honored drawing is reimbursed
by OpCo.

     2.7  Conversion/Continuation.

          (a) Subject to Section 2.17 and so long as no Default or Event of
Default shall have occurred and then be continuing, the applicable Borrower
shall have the option:

              (i)  to convert at any time all or any part of any Term Loan or
     Revolving Loan equal to $1,000,000 and integral multiples of $500,000 in
     excess of that amount from one Type of Loan to another Type of Loan;
     provided, a Eurodollar Rate Loan may only be converted on the expiration of
     --------
     the Interest Period applicable to such Eurodollar Rate Loan unless the
     applicable Borrower shall pay all amounts due  under Section 2.17 in
     connection with any such conversion; or

              (ii) upon the expiration of any Interest Period applicable to any
     Eurodollar Rate Loan, to continue all or any portion of such Loan equal to

                                       48
<PAGE>

     $1,000,000 and integral multiples of $500,000 in excess of that amount as a
     Eurodollar Rate Loan.

          (b) The applicable Borrower shall deliver a Conversion/Continuation
Notice to Administrative Agent no later than 10:00 a.m. (New York City time) at
least one (1) Business Day in advance of the proposed conversion date (in the
case of a conversion to a Base Rate Loan) and at least three (3) Business Days
in advance of the proposed conversion/continuation date (in the case of a
conversion to, or a continuation of, a Eurodollar Rate Loan).  Except as
otherwise provided herein, a Conversion/Continuation Notice for conversion to,
or continuation of, any Eurodollar Rate Loans (or telephonic notice in lieu
thereof) shall be irrevocable on and after the related Interest Rate
Determination Date, and the applicable Borrower shall be bound to effect a
conversion or continuation in accordance therewith.

     2.8  Default Interest.  Upon the occurrence and during the continuance of
an Event of Default described in Section 8.1(a), the principal amount of all
Loans and, to the extent permitted by applicable law, any interest payments on
the Loans or any fees or other amounts owed hereunder not paid when due, in each
case whether at stated maturity, by notice of prepayment, by acceleration or
otherwise, shall thereafter bear interest (including postpetition interest in
any proceeding under the Bankruptcy Code or other applicable bankruptcy laws)
payable on demand at a rate that is 2% per annum in excess of the interest rate
otherwise payable hereunder with respect to the applicable Loans (or, in the
case of any such fees and other amounts, at a rate which is 2% per annum in
excess of the interest rate otherwise payable hereunder for Base Rate Loans);
provided, in the case of Eurodollar Rate Loans, upon the expiration of the
--------
Interest Period in effect at the time any such increase in interest rate is
effective, such Eurodollar Rate Loans shall thereupon become Base Rate Loans and
shall thereafter bear interest payable upon demand at a rate which is 2% per
annum in excess of the interest rate otherwise payable hereunder for Base Rate
Loans.  Payment or acceptance of the increased rates of interest provided for in
this Section 2.8 is not a permitted alternative to timely payment and shall not
constitute a waiver of any Event of Default or otherwise prejudice or limit any
rights or remedies of Administrative Agent, any other Agent or any Lender.

     2.9  Fees.

          (a) Company agrees to pay from the time of the Closing Date to Lenders
having Term Loan Exposure, Delayed Draw Term Loan Exposure and/or Revolving
Exposure through Administrative Agent:

              (i)  a commitment fee equal to (1) the average of the daily unused
     Commitments of such Lender during the preceding Fiscal Quarter multiplied
     by, (2) the Applicable Commitment Fee Percentage; and

              (ii) Letter of Credit fees equal to (1) the Applicable Margin for
     Revolving Loans that are Eurodollar Rate Loans (other than Purchase Money
     Loans),  times (2) the average daily maximum amount available to be drawn
     under all such Letters of Credit (regardless of whether any conditions for
     drawing could then be met and determined as of the close of business on any
     date of determination).

                                       49
<PAGE>

              (iii)  All fees referred to in this Section 2.9(a) shall be paid
     to Administrative Agent at its Principal Office and upon receipt,
     Administrative Agent shall promptly distribute to each Lender its Pro Rata
     Share thereof.

          (b) OpCo agrees to pay directly to Issuing Bank, for its own account,
the following fees:

              (i)  a fronting fee equal to 0.25%, per annum, times the aggregate
     daily amount available to be drawn under all Letters of Credit (determined
     as of the close of business on any date of determination); and

              (ii) such documentary and processing charges for any issuance,
     amendment, transfer or payment of a Letter of Credit as are in accordance
     with Issuing Bank's standard schedules for such charges and as in effect at
     the time of such issuance, amendment, transfer or payment, as the case may
     be.

          (c) All fees referred to in Section 2.9(a) and 2.9(b)(i) shall be
calculated on the basis of a 360day year and the actual number of days elapsed
and shall be payable (i) quarterly in arrears on March 31, June 30, September 30
and December 31 of each year, commencing on the first such date to occur after
the Closing Date, (ii) on the Term Loan Commitment Termination Date (iii) on the
Delayed Draw Term Loan Commitment Termination Date and (iv) on the Revolving
Loan Commitment Termination Date.

          (d) In addition to any of the foregoing fees, Company agrees to pay to
Agents such other fees in the amounts and at the times separately agreed upon by
Company and such Agents thereby.

          (e) In addition, Company agrees to pay such commitment and other fees
as may be payable in connection with New Revolving Loan Commitments and New Term
Loan Commitments, if any, as set forth in the applicable Joinder Agreement or
otherwise agreed to in writing by Company.

     shall designate the date (which shall be a Business Day) of such
     termination or reduction and the amount of any partial reduction, and such
     termination or reduction of the Delayed Draw Term Loan Commitments and/or
     Revolving Loan Commitments, as applicable, shall be effective on the date
     specified in the applicable Borrower's notice and shall reduce the Delayed
     Draw Term Loan Commitments and/or Revolving Loan Commitment of each Lender
     proportionately to its Pro Rata Share thereof.

          (c) Prepayment/Reduction Premium.  Any voluntary prepayment (other
              ----------------------------
than prepayments of Revolving Loans) and/or Commitment reduction pursuant to

being so repaid, prepaid or Commitment reduced multiplied by 1.25%; and (ii)
                                               -------------

anniversary thereof, to the payment by the applicable Borrower of an amount
equal to the aggregate amount of the Loans being so repaid, prepaid or
Commitment reduced multiplied by 1%.
                   -------------

     2.12 Mandatory Prepayments/Commitment Reductions.

Asset Sale Proceeds, OpCo (or to the extent such Net Asset Sale Proceeds are
proceeds of the sale of assets of Company, Company) has not invested (or
committed to invest within 180 days and actually invested within a period of 270
days) such Net Asset Sale Proceeds in long term productive assets of the general
type used in the business of the Company and its Restricted Subsidiaries, as
certified to Administrative Agent by Company, then, to the extent Borrowers have
not previously done so, Borrowers shall prepay Loans and the Commitments shall
be permanently reduced as set forth in Section 2.13, in either case in an amount
equal to the excess of such Net Asset Sale Proceeds over amounts invested as
aforesaid; provided that, notwithstanding the foregoing, any prepayment under
           --------
this Section 2.12(a) on account of Net Asset Sale Proceeds from the sale or
other disposition of assets purchased with the proceeds of Purchase Money Loans
shall be used by Company immediately to prepay Purchase Money Loans.  Pending a

Asset Sale Proceeds shall be applied to prepay outstanding Revolving Loans
(without a reduction in the Revolving Loan Commitments).

          (b) Insurance/Condemnation Proceeds.  If, within the period of one
              -------------------------------
hundred eighty (180) days after the receipt by Company or any of its Restricted

                                       53
<PAGE>

Proceeds over amounts invested as aforesaid; provided, that, notwithstanding the
                                             --------
foregoing, any prepayment under this Section 2.12(b) arising due to Net
Insurance/Condemnation Proceeds in respect of assets purchased with the proceeds
of Purchase Money Loans shall be applied by Company to the prepayment of
Purchase Money Loans. Pending a determination on whether any Net
Insurance/Condemnation Proceeds shall be applied to prepay outstanding Loans
and/or reduce Commitments pursuant to the preceding sentence, such Net
Insurance/Condemnation Proceeds shall be applied to prepay outstanding Revolving
Loans (without a reduction in the Revolving Loan Commitments).

          (c) Consolidated Excess Cash Flow.  In the event that there shall be
              -----------------------------
Consolidated Excess Cash Flow for any Fiscal Year, commencing with Fiscal Year
2003, Borrowers shall, no later than ninety (90) days after the end of such
Fiscal Year, prepay the Loans and/or the Commitments shall be permanently

Revolving Loans to the extent necessary so that (i) the Total Utilization of
Revolving Loan Commitments shall not at any time exceed the Revolving Loan
Commitments then in effect and (ii) amounts outstanding under the A/R Sublimit
shall not at any time exceed 85% of Net Accounts Receivable. Company shall also
from time to time prepay the Delayed Draw Term Loans to the extent necessary so
that the Total Utilization of Delayed Draw Term Loan Commitments shall not at
any time exceed the Delayed Draw Term Loan Commitments then in effect.

          (e) Borrowing Base.  Borrowers shall from time to time prepay the
              --------------
Loans to the extent necessary so that the sum of (i) the aggregate principal
amount of all outstanding Term Loans plus (ii) the Total Utilization of
                                     ----
Revolving Loan Commitments plus (iii) the aggregate amount of all outstanding
                           ----
Delayed Draw Term Loans plus (iv) the aggregate amount of all New Term Loans, if
                        ----

              ----------------------
Loans and/or reduction of the Commitments pursuant to Sections 2.12(a) through
2.12(e), Borrowers shall deliver to Administrative Agent a certificate of an
Authorized Officer (a copy of which Administrative Agent shall promptly provide
to each Lender) demonstrating the calculation of the amount of the applicable
net proceeds or Consolidated Excess Cash Flow, as the case may be.  In the event
that Borrowers shall subsequently determine that the actual amount received
exceeded the amount set forth in such certificate, Borrowers shall promptly make
an additional prepayment of the Loans and/or the Commitments shall be
permanently reduced in an amount equal to such excess, and Borrowers shall
concurrently therewith deliver to Administrative Agent (a copy of which
Administrative Agent shall promptly provide to each Lender)  a certificate of an
Authorized Officer demonstrating the derivation of such excess.

          (g) Prepayment/Reduction Premium.  Any prepayment (other than
              ----------------------------
prepayments of Revolving Loans) and/or Commitment reduction pursuant to Sections
2.12(a) through 2.12(e) shall be subject (i) at any time prior to the first
anniversary of the Closing Date, to the payment by the applicable Borrower of an
amount equal to the aggregate amount of the Loans being so repaid, prepaid or
Commitment reduced multiplied by 1.25%; and (ii) after the
                   -------------

                                       54

first anniversary of the Closing Date but prior to the second anniversary
thereof, to the payment by the applicable Borrower of an amount equal to the
aggregate amount of the Loans being so repaid, prepaid or Commitment reduced
multiplied by 1.0%.
-------------

     2.13 Application of Prepayments/Reductions.

          (a) Application of Voluntary Prepayments by Type of Loans.  Any
              -----------------------------------------------------
prepayment of any Loan pursuant to Section 2.11(a) shall be applied as specified
by the applicable Borrower, in the applicable notice of prepayment; provided,
                                                                    --------
that such Borrower shall prepay all outstanding Purchase Money Loans prior to
prepaying any other Revolving Loans.  In the event a Borrower fails to specify
the Loans to which any such prepayment shall be applied, such prepayment shall
be applied as follows:

          first, to repay outstanding Purchase Money Loans to the full extent
thereof;

          second, to repay other outstanding Revolving Loans to the full extent
thereof; and

          third, to prepay the Term Loans, the Delayed Draw Term Loans and New
Term Loans, if any, on a pro rata basis (in accordance with the respective
outstanding principal amounts thereof).

Any prepayment of Term Loans and Delayed Draw Term Loans pursuant to Section
2.13(a) shall be further applied, on a pro rata basis, to the remaining
scheduled Term Loan Installments and Delayed Draw Term Loan Installments, as
applicable.

          (b) Application of Mandatory Prepayments by Type of Loans.  (i) Any
              -----------------------------------------------------
amount required to be prepaid pursuant to Section 2.12(a)(c) and (e) shall be
applied (unless otherwise specified in Section 2.12 with respect to Purchase
Money Loans) as follows:

          first, to prepay the Term Loans and Delayed Draw Term Loans (and to
further reduce any unused Delayed Draw Term Loan Commitments), and New Term
Loans, if any, on a pro rata basis (in accordance with the respective
outstanding principal amounts thereof) and (x) in the case of the Term Loans and
Delayed Draw Term Loans, shall be further applied to the remaining scheduled
Term Loan Installments or Delayed Draw Term Loan Installments, as applicable, in
inverse order of maturity and (y) in the case of New Term Loans, if any, shall
be applied pro rata among each outstanding Series and further applied to the
scheduled installments of principal of the New Term Loans of such Series in
inverse order of maturity;

          second, to prepay the Revolving Loans (with any Purchase Money Loans
being prepaid first) and to reduce the Revolving Loan Commitment);

          third, to prepay outstanding reimbursement obligations with respect to
Letters of Credit; and

          fourth, to cash collateralize Letters of Credit;

              (ii) Notwithstanding the foregoing, with respect to New Term
     Loans, a lesser amount may be required to be prepaid or waived if set forth
     in the

                                       55
<PAGE>

     applicable Joinder Agreement; provided that, any such amounts waived or not
                                   --------
     used to prepay New Term Loans shall be used to further prepay first, on a
     pro rata basis, Delayed Draw Term Loans and Term Loans and, second,
     Revolving Loans as provided above.

          (c) Application of Prepayments of Loans to Base Rate Loans and
              ----------------------------------------------------------
Eurodollar Rate Loans.  Considering each Class of Loans being prepaid
---------------------
separately, any prepayment thereof shall be applied first to Base Rate Loans to
the full extent thereof before application to Eurodollar Rate Loans, in each
case in a manner which minimizes the amount of any payments required to be made
by the applicable Borrower pursuant to Section 2.17(c).

     2.14 Allocation of Certain Payments and Proceeds.  If an Event of Default
shall have  occurred and not otherwise be waived, and the maturity of the
Obligations shall have been accelerated pursuant to Section 8.1, all payments or
proceeds received by Agents hereunder in respect of any of the Obligations,
shall be applied by Agents in accordance with the application arrangements
described in Section 6.5 of the Pledge and Security Agreement.

     2.15 General Provisions Regarding Payments.

          (a) All payments by a Borrower of principal, interest, fees and other
Obligations shall be made in Dollars in same day funds, without defense, setoff
or counterclaim, free of any restriction or condition, and delivered to
Administrative Agent not later than 12:00 p.m. (New York City time) on the date
due at the Administrative Agent's Principal Office for the account of Lenders;
funds received by Administrative Agent after that time on such due date shall be
deemed to have been paid by the applicable Borrower on the next succeeding
Business Day.

          (b) All payments in respect of the principal amount of any Loan (other
than voluntary prepayments of Revolving Loans) shall include payment of accrued
interest on the principal amount being repaid or prepaid, and all such payments
(and, in any event, any payments in respect of any Loan on a date when interest
is due and payable with respect to such Loan) shall be applied to the payment of
interest before application to principal.

          (c) Administrative Agent shall promptly distribute to each Lender at
such address as such Lender shall indicate in writing, such Lender's applicable
Pro Rata Share, giving effect to any adjustment from Pro Rata Shares on and
after the Closing Date, of all payments and prepayments of principal and
interest due hereunder, together with all other amounts due thereto, including,
without limitation, all fees payable with respect thereto, to the extent
received by Administrative Agent.

          (d) Notwithstanding the foregoing provisions hereof, if any
Conversion/Continuation Notice is withdrawn as to any Affected Lender or if any
Affected Lender makes Base Rate Loans in lieu of its Pro Rata Share of any
Eurodollar Rate Loans, Administrative Agent shall give effect thereto in
apportioning payments received thereafter.

          (e) Subject to the provisos set forth in the definition of "Interest
Period", whenever any payment to be made hereunder shall be stated to be due on
a day that is not a Business Day, such payment shall be made on the next
succeeding Business Day and such

                                       56
<PAGE>

extension of time shall be included in the computation of the payment of
interest hereunder or of the Revolving Loan Commitment fees hereunder.

          (f) Each Borrower hereby authorizes Administrative Agent to charge its
accounts with Administrative Agent in order to cause timely payment to be made
to Administrative Agent of all principal, interest, fees and expenses due
hereunder (subject to sufficient funds being available in its accounts for that
purpose).

          (g) Administrative Agent shall deem any payment by or on behalf of a
Borrower hereunder that is not made in same day funds prior to 12:00 p.m. (New
York City time) on or before the due date to be a nonconforming payment.  Any
such payment shall not be deemed to have been received by Administrative Agent
until the later of (i) the time such funds become available funds, and (ii) the
applicable next Business Day.  Administrative Agent shall give prompt telephonic
notice to the applicable Borrower and each applicable Lender (confirmed in
writing) if any payment is nonconforming.  Any nonconforming payment may
constitute or become a Default or Event of Default in accordance with the terms
of Section 8.1(a).  Interest shall continue to accrue on any principal as to
which a nonconforming payment is made until such funds become available funds
(but in no event less than the period from the date of such payment to the next
succeeding applicable Business Day) at the rate determined pursuant to Section
2.8 from the date such amount was due and payable until the date such amount is
paid in full.

     2.16 Ratable Sharing.  Lenders hereby agree among themselves that, except
as otherwise provided  in the Collateral Documents with respect to amounts
realized from the exercise of rights with respect to Liens on the Collateral, if
any of them shall, whether by voluntary payment (other than a voluntary
prepayment of Loans made and applied in accordance with the terms hereof),
through the exercise of any right of setoff or banker's lien, by counterclaim or
cross action or by the enforcement of any right under the Credit Documents or
otherwise, or as adequate protection of a deposit treated as cash collateral
under the Bankruptcy Code, receive payment or reduction of a proportion of the
aggregate amount of principal, interest, amounts payable in respect of Letters
of Credit, fees and other amounts then due and owing to such Lender hereunder or
under the other Credit Documents (collectively, the "Aggregate Amounts Due" to
such Lender) which is greater than the proportion received by any other Lender
in respect of the Aggregate Amounts Due to such other Lender, then the Lender
receiving such proportionately greater payment shall notify Administrative Agent
and each other Lender of the receipt of such payment and apply a portion of such
payment to purchase participations (which it shall be deemed to have purchased
from each seller of a participation simultaneously upon the receipt by such
seller of its portion of such payment) in the Aggregate Amounts Due to the other
Lenders so that all such recoveries of Aggregate Amounts Due shall be shared by
all Lenders in proportion to the Aggregate Amounts Due to them; provided, if all
                                                                --------
or part of such proportionately greater payment received by such purchasing
Lender is thereafter recovered from such Lender upon the bankruptcy or
reorganization of a Credit Party or otherwise, those purchases shall be
rescinded and the purchase prices paid for such participations shall be promptly
returned to such purchasing Lender ratably to the extent of such recovery, but
without interest.  Each Borrower expressly consents to the foregoing arrangement
and agrees that any holder of a participation so purchased may exercise any and
all rights of banker's lien, setoff or counterclaim with respect to any and all
monies owing by the

                                       57
<PAGE>

applicable Borrower to that holder with respect thereto as fully as if that
holder were owed the amount of the participation held by that holder.

     2.17 Making or Maintaining Eurodollar Rate Loans.

          (a) Inability to Determine Applicable Interest Rate.  In the event
              -----------------------------------------------
that Administrative Agent shall have determined (which determination shall be
final and conclusive and binding upon all parties hereto), on any Interest Rate
Determination Date with respect to any Eurodollar Rate Loans, that by reason of
circumstances affecting the London interbank market adequate and fair means do
not exist for ascertaining the interest rate applicable to such Loans on the
basis provided for in the definition of Adjusted Eurodollar Rate, Administrative
Agent shall on such date give notice (by telefacsimile or by telephone confirmed
in writing) to the applicable Borrower and each Lender of such determination,
whereupon no Loans may be made as, or converted to, Eurodollar Rate Loans until
such time as Administrative Agent notifies  the applicable Borrower and Lenders
(by telefacsimile or by telephonic notice confirmed in writing) that the
circumstances giving rise to such notice no longer exist, and any Funding Notice
or Conversion/Continuation Notice given by  the applicable Borrower with respect
to the Loans in respect of which such determination was made shall be deemed to
be, in the case of a Conversion Notice, rescinded by  the applicable Borrower
and, in the case of a Funding Notice, deemed to be a Funding Notice in respect
of Base Rate Loans.

          (b) Illegality or Impracticability of Eurodollar Rate Loans.  In the
              -------------------------------------------------------
event that on any date any Lender shall have determined (which determination
shall be final and conclusive and binding upon all parties hereto but shall be
made only after consultation with  the applicable Borrower and Administrative
Agent) that the making, maintaining or continuation of its Eurodollar Rate Loans
has become unlawful as a result of compliance by such Lender in good faith with
any law, treaty, governmental rule, regulation, guideline or order (or would
conflict with any such treaty, governmental rule, regulation, guideline or order
not having the force of law even though the failure to comply therewith would
not be unlawful), or has become impracticable, as a result of contingencies
occurring after the date hereof which materially and adversely affect the London
interbank market or the position of such Lender in that market, then, and in any
such event, such Lender shall be an "Affected Lender" and it shall on that day
give notice (by telefacsimile or by telephone confirmed in writing) to  the
applicable Borrower and Administrative Agent of such determination (which notice
Administrative Agent shall promptly transmit to each other Lender and by
telefacsimile or telephonic notice confirmed in writing).  Thereafter the
obligation of the Affected Lender to make Loans as, or to convert Loans to,
Eurodollar Rate Loans shall be suspended until such notice shall be withdrawn by
the Affected Lender, to the extent such determination by the Affected Lender
relates to a Eurodollar Rate Loan then being requested by  the applicable
Borrower pursuant to a Funding Notice or a Conversion/Continuation Notice, the
Affected Lender shall make such Loan as (or continue such Loan as or convert
such Loan to, as the case may be) a Base Rate Loan, the Affected Lender's
obligation to maintain its outstanding Eurodollar Rate Loans (the "Affected
Loans") shall be terminated at the earlier to occur of the expiration of the
Interest Period then in effect with respect to the Affected Loans or when
required by law, and the Affected Loans shall automatically convert into Base
Rate Loans on the date of such termination. Notwithstanding the foregoing, to
the extent a determination by an Affected Lender as described above relates to a
Eurodollar Rate Loan then being requested by the applicable Borrower pursuant to
a Funding

                                       58
<PAGE>

Notice or a Conversion/Continuation Notice, the applicable Borrower shall have
the option, subject to the provisions of Section 2.17(c), to rescind such
Funding Notice or Conversion/Continuation Notice as to all Lenders by giving
notice (by telefacsimile or by telephone confirmed in writing) to Administrative
Agent of such rescission on the date on which the Affected Lender gives notice
of its determination as described above (which notice of rescission
Administrative Agent shall promptly transmit to each other Lender by
telefacsimile or by telephonic notice confirmed in writing). Except as provided
in the immediately preceding sentence, nothing in this Section 2.17(b) shall
affect the obligation of any Lender other than an Affected Lender to make or
maintain Loans as, or to convert Loans to, Eurodollar Rate Loans in accordance
with the terms hereof.

          (c) Compensation for Breakage or NonCommencement of Interest Periods.
              ----------------------------------------------------------------
The applicable Borrower shall compensate each Lender, upon written request by
such Lender (which request shall set forth the basis for requesting such
amounts), for all reasonable losses, expenses and liabilities (including any
interest paid by such Lender to lenders of funds borrowed by it to make or carry
its Eurodollar Rate Loans and any loss, expense or liability sustained by such
Lender in connection with the liquidation or reemployment of such funds but
excluding loss of anticipated profits) which such Lender may sustain if for any
reason as a result of Borrower's action or omission a borrowing of any
Eurodollar Rate Loan does not occur on a date specified therefor in a Funding
Notice or a telephonic request for borrowing, or a conversion to or continuation
of any Eurodollar Rate Loan does not occur on a date specified therefor in a
Conversion/Continuation Notice or a telephonic request for conversion or
continuation;  if any prepayment or other principal payment or any conversion of
any of its Eurodollar Rate Loans occurs on a date prior to the last day of an
Interest Period applicable to that Loan; or  if any prepayment of any of its
Eurodollar Rate Loans is not made on any date specified in a notice of
prepayment given by  such Borrower or as a consequence of any default by such
Borrower in the repayment of its Eurodollar Rate Loans when required by the
terms thereof.

          (d) Booking of Eurodollar Rate Loans.  Any Lender may make, carry or
              --------------------------------
transfer Eurodollar Rate Loans at, to, or for the account of any of its branch
offices or the office of an Affiliate of such Lender.

          (e) Assumptions Concerning Funding of Eurodollar Rate Loans.
              -------------------------------------------------------
Calculation of all amounts payable to a Lender under this Section 2.17 and under
Section 2.18 shall be made as though such Lender had actually funded each of its
relevant Eurodollar Rate Loans through the purchase of a Eurodollar deposit
bearing interest at the rate obtained pursuant to clause (i) of the definition
of Adjusted Eurodollar Rate in an amount equal to the amount of such Eurodollar
Rate Loan and having a maturity comparable to the relevant Interest Period and
through the transfer of such Eurodollar deposit from an offshore office of such
Lender to a domestic office of such Lender in the United States of America;
provided, however, each Lender may fund each of its Eurodollar Rate Loans in any
--------  -------
manner it sees fit and the foregoing assumptions shall be utilized only for the
purposes of calculating amounts payable under this Section 2.17 and under
Section 2.18.

     2.18 Increased Costs; Capital Adequacy.

          (a) Compensation For Increased Costs and Taxes.  Subject to the
              ------------------------------------------
provisions of Section 2.19 (which shall be controlling with respect to the
matters covered thereby), in the event that any Lender (which term shall include
Issuing Bank for purposes of this Section 2.18(a)) shall determine (which
determination shall, absent manifest error, be final and conclusive and binding
upon all parties hereto) that any law, treaty or governmental rule, regulation
or order, or any change therein or in the interpretation, administration or
application thereof (including the introduction of any new law, treaty or
governmental rule, regulation or order), or any determination of a court or
Governmental Authority, in each case that becomes effective after the date
hereof, or compliance by such Lender with any guideline, request or directive
issued or made after the date hereof by any central bank or other governmental
or quasigovernmental authority (whether or not having the force of law):
subjects such Lender (or its applicable lending office) to any additional Tax
(other than any Tax on the overall net income of such Lender) with respect to
this Agreement or any of its obligations hereunder or any payments to such
Lender (or its applicable lending office) of principal, interest, fees or any
other amount payable hereunder or thereunder; imposes, modifies or holds
applicable any reserve (including any marginal, emergency, supplemental, special
or other reserve), special deposit, compulsory loan, FDIC insurance or similar
requirement against assets held by, or deposits or other liabilities in or for
the account of, or advances or loans by, or other credit extended by, or any
other acquisition of funds by, any office of such Lender (other than any such
reserve or other requirements with respect to Eurodollar Rate Loans that are
reflected in the definition of Adjusted Eurodollar Rate); or imposes any other
condition (other than with respect to a Tax matter) on or affecting such Lender
(or its applicable lending office) or its obligations hereunder or under any
other Credit Document or the London interbank market; and the result of any of
the foregoing is to increase the cost to such Lender of agreeing to make, making
or maintaining Eurodollar Rate Loans hereunder or to reduce any amount received
or receivable by such Lender (or its applicable lending office) with respect
thereto; then, in any such case,  the applicable Borrower shall promptly pay to
such Lender, upon receipt of the statement referred to in the next sentence,
such additional amount or amounts (in the form of an increased rate of, or a
different method of calculating, interest or otherwise as such Lender in its
sole discretion shall determine) as may be necessary to compensate such Lender
for any such increased cost or reduction in amounts received or receivable
hereunder or under any other Credit Document.  Such Lender shall deliver to  the
applicable Borrower (with a copy to Administrative Agent) a written statement,
setting forth in reasonable detail the basis for calculating the additional
amounts owed to such Lender under this Section 2.18(a), which statement shall be
conclusive and binding upon all parties hereto absent manifest error.

          (b) Capital Adequacy Adjustment.  In the event that any Lender (which
              ---------------------------
term shall include Issuing Bank for purposes of this Section  2.18(b)) shall
have determined that the adoption, effectiveness, phasein or applicability after
the date hereof of any law, rule or regulation (or any provision thereof)
regarding capital adequacy, or any change therein or in the interpretation or
administration thereof by any Governmental Authority, central bank or comparable
agency charged with the interpretation or administration thereof, or compliance
by any Lender (or its applicable lending office) with any guideline, request or
directive regarding capital adequacy (whether or not having the force of law) of
any such Governmental Authority, central bank or comparable agency, has or would
have the effect of reducing the rate of return on

                                       60
<PAGE>

the capital of such Lender or any corporation controlling such Lender as a
consequence of, or with reference to, such Lender's Loans or Commitments or
Letters of Credit, or participations therein or other obligations hereunder with
respect to the Loans or the Letters of Credit to a level below that which such
Lender or such controlling corporation could have achieved but for such
adoption, effectiveness, phasein, applicability, change or compliance (taking
into consideration the policies of such Lender or such controlling corporation
with regard to capital adequacy), then from time to time, within five (5)
Business Days after receipt by the applicable Borrower from such Lender of the
statement referred to in the next sentence, the applicable Borrower shall pay to
such Lender such additional amount or amounts as will compensate such Lender or
such controlling corporation on an aftertax basis for such reduction. Such
Lender shall deliver to the applicable Borrower (with a copy to Administrative
Agent) a written statement, setting forth in reasonable detail the basis for
calculating the additional amounts owed to Lender under this Section 2.18(b),
which statement shall be conclusive and binding upon all parties hereto absent
manifest error.

          (c) Limitation on Retroactive Effect. Failure or delay on the part of
              --------------------------------
any Lender to demand compensation pursuant to this Section 2.18 shall not
constitute a waiver of such Lender's right to demand such compensation;
provided, however, that the Borrowers shall not be required to compensate a
--------  -------
Lender pursuant to this Section 2.18 for any increased costs or reductions
incurred more than 180 days prior to the date that such Lender notifies
Borrowers of the change giving rise to such increased costs or reductions and of
such Lender's intention to claim compensation therefor; provided further that if
                                                        -------- -------
the change giving rise to such increased costs or reductions is retroactive,
then the 180-day period referred to above shall be extended to include the
period of retroactive effective thereof.

     2.19 Taxes; Withholding, etc.

          (a) Payments to Be Free and Clear.  All sums payable by any Credit
              -----------------------------
Party hereunder and under the other Credit Documents shall (except to the extent
required by law) be paid free and clear of, and without any deduction or
withholding on account of, any Tax (other than a Tax on the overall net income
of any Lender) imposed, levied, collected, withheld or assessed by or within the
United States of America or any political subdivision in or of the United States
of America or any other jurisdiction from or to which a payment is made by or on
behalf of any Credit Party or by any federation or organization of which the
United States of America or any such jurisdiction is a member at the time of
payment.

          (b) Withholding of Taxes.  If any Credit Party or any other Person is
              --------------------
required by law to make any deduction or withholding on account of any such Tax
from any sum paid or payable by any Credit Party to Administrative Agent or any
Lender (which term shall include Issuing Bank for purposes of this Section
2.19(b)) under any of the Credit Documents:  the applicable Borrower shall
notify Administrative Agent of any such requirement or any change in any such
requirement as soon as the applicable Borrower becomes aware of it; the
applicable Borrower shall pay any such Tax before the date on which penalties
attach thereto, such payment to be made (if the liability to pay is imposed on
any Credit Party) for its own account or (if that liability is imposed on
Administrative Agent or such Lender, as the case may be) on behalf of and in the
name of Administrative Agent or such Lender;  the sum payable by such Credit
Party in respect of which the relevant deduction, withholding or payment is
required shall be increased

                                       61
<PAGE>

to the extent necessary to ensure that, after the making of that deduction,
withholding or payment, Administrative Agent or such Lender, as the case may be,
receives on the due date a net sum equal to what it would have received had no
such deduction, withholding or payment been required or made; and within thirty
(30) days after paying any sum from which it is required by law to make any
deduction or withholding, and within thirty (30) days after the due date of
payment of any Tax which it is required by clause (ii) above to pay, the
applicable Borrower shall deliver to Administrative Agent and the other affected
parties evidence satisfactory to the other affected parties of such deduction,
withholding or payment and of the remittance thereof to the relevant taxing or
other authority; provided, no such additional amount shall be required to be
paid to any Lender under clause (iii) above except to the extent that any change
after the date hereof (in the case of each Lender listed on the signature pages
hereof on the Closing Date) or after the effective date of the Assignment
Agreement or Joinder Agreement pursuant to which such Lender became a Lender (in
the case of each other Lender) in any such requirement for a deduction,
withholding or payment as is mentioned therein shall result in an increase in
the rate of such deduction, withholding or payment from that in effect at the
date hereof or at the date of such Assignment Agreement or Joinder Agreement, as
the case may be, in respect of payments to such Lender.

          (c) Evidence of Exemption From U.S. Withholding Tax.  Each Lender that
              -----------------------------------------------
is not a United States Person (as such term is defined in Section 7701(a)(30) of
the Internal Revenue Code) for U.S. federal income tax purposes (a "NonUS
Lender") shall deliver to Administrative Agent for transmission to the
applicable Borrower, on or prior to the Closing Date (in the case of each Lender
listed on the signature pages hereof on the Closing Date) or on or prior to the
date of the Assignment Agreement or Joinder Agreement pursuant to which it
becomes a Lender (in the case of each other Lender), and at such other times as
may be necessary in the determination of the applicable Borrower or
Administrative Agent (each in the reasonable exercise of its discretion),  two
original copies of Internal Revenue Service Form W8BEN or W8ECI (or any
successor forms), properly completed and duly executed by such Lender, and such
other documentation required under the Internal Revenue Code and reasonably
requested by the applicable Borrower to establish that such Lender is not
subject to deduction or withholding of United States federal income tax with
respect to any payments to such Lender of principal, interest, fees or other
amounts payable under any of the Credit Documents, or  if such Lender is not a
"bank" or other Person described in Section 881(c)(3) of the Internal Revenue
Code and cannot deliver either Internal Revenue Service Form W8BEN or W8ECI
pursuant to clause (i) above, a Certificate re NonBank Status together with two
original copies of Internal Revenue Service Form W8 (or any successor form),
properly completed and duly executed by such Lender, and such other
documentation required under the Internal Revenue Code and reasonably requested
by the applicable Borrower to establish that such Lender is not subject to
deduction or withholding of United States federal income tax with respect to any
payments to such Lender of interest payable under any of the Credit Documents.
Each Lender required to deliver any forms, certificates or other evidence with
respect to United States federal income tax withholding matters pursuant to this
Section 2.19(c) hereby agrees, from time to time after the initial delivery by
such Lender of such forms, certificates or other evidence, whenever a lapse in
time or change in circumstances renders such forms, certificates or other
evidence obsolete or inaccurate in any material respect, that such Lender shall
promptly deliver to Administrative Agent for transmission to the applicable
Borrower two new original copies of Internal Revenue Service Form W8BEN or
W8ECI, or a Certificate re NonBank Status and two original copies of

                                       62
<PAGE>

Internal Revenue Service Form W8, as the case may be, properly completed and
duly executed by such Lender, and such other documentation required under the
Internal Revenue Code and reasonably requested by the applicable Borrower to
confirm or establish that such Lender is not subject to deduction or withholding
of United States federal income tax with respect to payments to such Lender
under the Credit Documents, or notify Administrative Agent and the applicable
Borrower of its inability to deliver any such forms, certificates or other
evidence. The applicable Borrower shall not be required to pay any additional
amount to any NonUS Lender under Section 2.19(b)(iii) if such Lender shall have
failed to deliver the forms, certificates or other evidence referred to in the
second sentence of this Section 2.19(c), or (2) to notify Administrative Agent
and the applicable Borrower of its inability to deliver any such forms,
certificates or other evidence, as the case may be; provided, if such Lender
                                                    --------
shall have satisfied the requirements of the first sentence of this Section
2.19(c) on the Closing Date or on the date of the Assignment Agreement or
Joinder Agreement pursuant to which it became a Lender, as applicable, nothing
in this last sentence of Section 2.19(c) shall relieve the applicable Borrower
of its obligation to pay any additional amounts pursuant to Section 2.18(a) in
the event that, as a result of any change in any applicable law, treaty or
governmental rule, regulation or order, or any change in the interpretation,
administration or application thereof, such Lender is no longer properly
entitled to deliver forms, certificates or other evidence at a subsequent date
establishing the fact that such Lender is not subject to withholding as
described herein.

     2.20 Obligation to Mitigate.  Each Lender (which term shall include Issuing
Bank for purposes of this Section 2.21) agrees that, as promptly as practicable
after the officer of such Lender responsible for administering its Loans or
Letters of Credit, as the case may be, becomes aware of the occurrence of an
event or the existence of a condition that would cause such Lender to become an
Affected Lender or that would entitle such Lender to receive payments under
Section 2.17, 2.18 or 2.20, it will, to the extent not inconsistent with the
internal policies of such Lender and any applicable legal or regulatory
restrictions, (i) use reasonable efforts to  make, issue, fund or maintain its
applicable Commitments or Loans, including any Affected Loans, through another
office of such Lender, or  (ii) take such other measures as such Lender may deem
reasonable, if as a result thereof the circumstances which would cause such
Lender to be an Affected Lender would cease to exist or the additional amounts
which would otherwise be required to be paid to such Lender pursuant to Section
2.17, 2.18 or 2.19 would be materially reduced and if, as determined by such
Lender in its sole discretion, the making, issuing, funding or maintaining of
such Commitments, Loans or Letters of Credit through such other office or in
accordance with such other measures, as the case may be, would not otherwise
adversely affect such Commitments, Loans or Letters of Credit or the interests
of such Lender; provided, such Lender will not be obligated to utilize such
                --------
other office pursuant to this Section 2.21 unless the applicable Borrower agrees
to pay all incremental expenses incurred by such Lender as a result of utilizing
such other office as described in clause (i) above.  A certificate as to the
amount of any such expenses payable by the applicable Borrower pursuant to this
Section 2.21 (setting forth in reasonable detail the basis for requesting such
amount) submitted by such Lender to the applicable Borrower (with a copy to
Administrative Agent) shall be conclusive absent manifest error.

     2.21 Defaulting Lenders.  Anything contained herein to the contrary
notwithstanding, in the event that any Lender defaults (a "Defaulting Lender")
in its obligation to fund (a "Funding Default") any Loan or its portion of any
unreimbursed payment under Section 2.2(e)

                                       63
<PAGE>

(in each case, a "Defaulted Loan"), then (a) during any such period when such
default is continuing with respect to such Defaulting Lender (the "Default
Period"), such Defaulting Lender shall not be deemed to be a "Lender" for
purposes of voting on any matters (including the granting of any consents or
waivers) with respect to any of the Credit Documents; (b) to the extent
permitted by applicable law, until such time as the Default Excess with respect
to such Defaulting Lender shall have been reduced to zero, any voluntary
prepayment of the Loans shall, if the applicable Borrower so directs at the time
of making such voluntary prepayment, be applied to the Loans of other Lenders as
if such Defaulting Lender had no Loans outstanding and the Delayed Draw Term
Loan Exposure and the Revolving Loan Exposure of such Defaulting Lender were
zero, and any mandatory prepayment of the Loans shall, if the applicable
Borrower so directs at the time of making such mandatory prepayment, be applied
to the Loans of other Lenders (but not to the Loans of such Defaulting Lender),
it being understood and agreed that the applicable Borrower shall be entitled to
retain any portion of any mandatory prepayment of the Loans that is not paid to
such Defaulting Lender solely as a result of the operation of the provisions of
this clause (b); (c) such Defaulting Lender's Delayed Draw Term Loan Commitment
and Revolving Loan Commitment and outstanding Loans and such Defaulting Lender's
Pro Rata Share of the Letter of Credit Usage shall be excluded for purposes of
calculating the commitment fee payable to Lenders in respect of any day during
any Default Period with respect to such Defaulting Lender, and such Defaulting
Lender shall not be entitled to receive any commitment fee pursuant to Section
2.9 with respect to such Defaulting Lender's Revolving Loan Commitment and
Delayed Draw Term Loan Commitment in respect of any Default Period with respect
to such Defaulting Lender; and (d) the Total Utilization of Commitments as at
any date of determination shall be calculated as if such Defaulting Lender had
funded all Defaulted Loans of such Defaulting Lender. No Revolving Loan
Commitment or Delayed Draw Term Loan Commitment of any Lender shall be increased
or otherwise affected, and, except as otherwise expressly provided in this
Section 2.21, performance by the applicable Borrower of its obligations
hereunder and the other Credit Documents shall not be excused or otherwise
modified as a result of any Funding Default or the operation of this Section
2.21. The rights and remedies against a Defaulting Lender under this Section
2.21 are in addition to other rights and remedies which the applicable Borrower
may have against such Defaulting Lender with respect to any Funding Default and
which Administrative Agent or any Lender may have against such Defaulting Lender
with respect to any Funding Default.

     2.22 Removal or Replacement of a Lender.  Anything contained herein to the
contrary notwithstanding, in the event that: (i) any Lender (an "IncreasedCost
Lender") shall give notice to the applicable Borrower that such Lender is an
Affected Lender or that such Lender is entitled to receive payments under
Section  2.17, 2.18 or 2.19, the circumstances which have caused such Lender to
be an Affected Lender or which entitle such Lender to receive such payments
shall remain in effect, and such Lender shall fail to withdraw such notice
within five (5) Business Days after the applicable Borrower's request for such
withdrawal; or (ii) any Lender shall become a Defaulting Lender, the Default
Period for such Defaulting Lender shall remain in effect, and such Defaulting
Lender shall fail to cure the default as a result of which it has become a
Defaulting Lender within five (5) Business Days after the applicable Borrower's
request that it cure such default; or (iii) in connection with any proposed
amendment, modification, termination, waiver or consent with respect to any of
the provisions hereof as contemplated by Section 10.5(b), the consent of
Requisite Lenders shall have been obtained but the consent of one or more of
such other Lenders (each a "NonConsenting Lender") whose consent is required

                                       64
<PAGE>

shall not have been obtained; then, with respect to each such IncreasedCost
Lender, Defaulting Lender or NonConsenting Lender (the "Terminated Lender"), the
applicable Borrower may, by giving written notice to Administrative Agent and
any Terminated Lender of its election to do so, elect to cause such Terminated
Lender (and such Terminated Lender hereby irrevocably agrees) to assign its
outstanding Loans and its Revolving Loan Commitments, if any, and/or Delayed
Draw Term Loan Commitment, if any, in full to one or more Eligible Assignees
(each a "Replacement Lender") in accordance with the provisions of Section 10.6
and Terminated Lender shall pay any fees payable thereunder in connection with
such assignment; provided, (1) on the date of such assignment, the Replacement
                 --------
Lender shall pay to Terminated Lender an amount equal to the sum of (A) an
amount equal to the principal of, and all accrued interest on, all outstanding
Loans of the Terminated Lender, (B) an amount equal to all unreimbursed drawings
that have been funded by such Terminated Lender, together with all then unpaid
interest with respect thereto at such time and (C) an amount equal to all
accrued, but theretofore unpaid fees owing to such Terminated Lender pursuant to
Section 2.9; (2) on the date of such assignment, the applicable Borrower shall
pay any amounts payable to such Terminated Lender pursuant to Section 2.17(c),
2.18 or 2.19 or otherwise as if it were a prepayment; and (3) in the event such
Terminated Lender is a NonConsenting Lender, each Replacement Lender shall
consent, at the time of such assignment, to each matter in respect of which such
Terminated Lender was a NonConsenting Lender; provided, such Borrower may not
                                              --------
make such election with respect to any Terminated Lender that is also an Issuing
Bank unless, prior to the effectiveness of such election, Company shall have
caused each outstanding Letter of Credit issued thereby to be cancelled.  Upon
the prepayment of all amounts owing to any Terminated Lender and the termination
of such Terminated Lender's Revolving Loan Commitments, if any,  and/or Delayed
Draw Term Loan Commitment, if any, such Terminated Lender shall no longer
constitute a "Lender" for purposes hereof; provided, any rights of such
                                           --------
Terminated Lender to indemnification hereunder shall survive as to such
Terminated Lender.

carry out the transactions contemplated thereby, and (c) is qualified to do
business and in good standing in every jurisdiction where its assets are located
and wherever necessary to carry out its business and operations, except in
jurisdictions where the failure to be so qualified or in good standing has not

     4.2  Capital Stock and Ownership.  The Capital Stock of each of the Credit
Parties has been duly authorized and validly issued and is fully paid and
nonassessable.  Except as set forth on Schedule 4.2, as of the date hereof,
there is no existing option, warrant, call, right, commitment or other agreement
to which any of the Credit Parties, other than the Company, is a party
requiring, and there is no membership interest or other Capital Stock of any of
the Credit Parties, other than the Company, outstanding which upon conversion or
exchange would require, the issuance by any of the Credit Parties, other than
the Company, of any additional membership interests or other Capital Stock of
any of the Credit Parties, other than the Company, or other Securities
convertible into, exchangeable for or evidencing the right to subscribe for or
purchase, a membership interest or other Capital Stock of any of the Credit
Parties, other than the Company.  Schedule 4.2 correctly sets forth the
ownership interest of the Credit Parties in their respective Subsidiaries as of
the Closing Date.

     4.4  No Conflict.  The execution, delivery and performance by the Credit
Parties of the Credit Documents to which they are parties and the consummation
of the transactions contemplated by the Credit Documents do not and will not
violate any provision of any law or any governmental rule or regulation
applicable to any of the Credit Parties, any of the Organizational Documents of
any of the Credit Parties, or any order, judgment or decree of any court or

     4.5  Governmental Consents.  The execution, delivery and performance by
Credit Parties of the Credit Documents to which they are parties and the
consummation of the transactions contemplated by the Credit Documents do not and
will not require any registration with, consent or approval of, or notice to, or
other action to, with or by, any Governmental Authority except as otherwise set
forth on Schedule 4.5, and except for filings and recordings with respect to the
Collateral to be made, or otherwise delivered to Collateral Agent for filing
and/or recordation, as of the Closing Date.

     4.6  Binding Obligation.  Each Credit Document has been duly executed and
delivered by each Credit Party that is a party thereto and is the legally valid
and binding obligation of such Credit Party, enforceable against such Credit
Party in accordance with its respective terms, except as may be limited by
bankruptcy, insolvency, reorganization, moratorium or similar laws relating to

entities described therein for each of the periods then ended, subject, in the
case of any such unaudited financial statements, to changes resulting from audit
and normal yearend adjustments.  As of the Closing Date, neither Company nor any
of its Subsidiaries has any contingent liability or liability for taxes,
longterm lease or unusual forward or longterm commitment that is not reflected
in the Historical Financial Statements or the notes thereto and which in any
such case is material in relation to the business, operations, properties,
assets, condition (financial or otherwise) or prospects of Company and any of
its Subsidiaries taken as a whole.

     4.8  Projections.  On and as of the Closing Date, the financial forecast of

Employee Benefit Plan which is intended to qualify under Section 401(a) of the
Internal Revenue Code is so qualified.  No material liability to the PBGC (other

valuation date for each Multiemployer Plan for which the actuarial report is

ERISA Affiliates for a complete withdrawal from such Multiemployer Plan (within
the meaning of Section 4203 of ERISA), when aggregated with such potential
liability for a complete withdrawal from all Multiemployer Plans, based on
information available pursuant to Section 4221(e) of ERISA, does not exceed
$1,500,000.  Each of the Credit Parties and each of their ERISA Affiliates have
complied with the requirements of Section 515 of ERISA with respect to each
Multiemployer Plan and are not in material "default" (as defined in Section
4219(c)(5) of ERISA) with respect to payments to a Multiemployer Plan.

SECTION 7 GUARANTY

     7.1  Guaranty of the Obligations.  Subject to the provisions of Section
7.2, Guarantors jointly and severally hereby irrevocably and unconditionally
guaranty to Administrative Agent for the ratable benefit of the Beneficiaries
the due and punctual payment in full of all Obligations when the same shall
become due, whether at stated maturity, by required prepayment, declaration,
acceleration, demand or otherwise (including amounts that would become due but
for the operation of the automatic stay under Section 362(a) of the Bankruptcy
Code, 11 U.S.C. (S) 362(a)) (collectively, the "Guaranteed Obligations");
provided that Company's obligations with respect to Purchase Money Loans shall
--------
be included in the defined term Guaranteed Obligations only to the extent not
violative of the Senior Notes.

     7.2  Contribution by Guarantors.  Each Guarantor desires to allocate among
themselves (collectively, the "Contributing Guarantors"), in a fair and
equitable manner, their obligations arising under this Guaranty.  Accordingly,
in the event any payment or distribution is made on any date by a Guarantor (a
"Funding Guarantor") under this Guaranty that exceeds its Fair Share as of such
date, such Funding Guarantor shall be entitled to a contribution from each of
the other Contributing Guarantors in the amount of such other Contributing
Guarantor's Fair Share Shortfall as of such date, with the result that all such
contributions will cause each Contributing Guarantor's Aggregate Payments to
equal its Fair Share as of such date.  "Fair Share" means, with respect to a
Contributing Guarantor as of any date of determination, an amount equal to  the
ratio of  the Fair Share Contribution Amount with respect to such Contributing
Guarantor to  the aggregate of the Fair Share Contribution Amounts with respect
to all Contributing Guarantors multiplied by  the aggregate amount paid or
distributed on or before such date by all Funding Guarantors under this Guaranty
in respect of the obligations Guaranteed.  "Fair Share Shortfall" means, with
respect to a Contributing Guarantor as of any date of determination, the excess,
if any, of the Fair Share of such Contributing Guarantor over the Aggregate
Payments of such Contributing Guarantor.  "Fair Share Contribution Amount"
means, with respect to a Contributing Guarantor as of any date of determination,
the maximum aggregate amount of the obligations of such Contributing Guarantor
under this Guaranty that would not render its obligations hereunder or
thereunder subject to avoidance as a fraudulent transfer or conveyance under
Section 548 of Title 11 of the United States Code or any comparable applicable
provisions of state law; provided, solely for purposes of calculating the "Fair
                         --------
Share Contribution Amount" with respect to any Contributing Guarantor for
purposes of this Section 7.2, any assets or liabilities of such Contributing
Guarantor arising by virtue of any rights to subrogation, reimbursement or
indemnification or any rights to or obligations of contribution hereunder shall
not be considered as assets or liabilities of such Contributing Guarantor.
"Aggregate Payments" means, with respect to a Contributing Guarantor as of any
date of determination, an amount equal to  the aggregate amount of all payments
and distributions made on or before such date by such Contributing Guarantor in
respect of this Guaranty (including, without limitation, in respect of this
Section 7.2), minus  the aggregate amount of all payments received on or before
such date by such Contributing Guarantor from the other Contributing Guarantors
as contributions under this Section 7.2.  The amounts payable as contributions
hereunder shall be determined as of the date on which the related payment or
distribution is made by the applicable Funding Guarantor.  The allocation among
Contributing Guarantors of their obligations as set forth in this Section 7.2
shall not be construed in any way

                                       99
<PAGE>

to limit the liability of any Contributing Guarantor hereunder. Each Guarantor
is a third party beneficiary to the contribution agreement set forth in this
Section 7.2.

     7.3  Payment by Guarantors.  Subject to Section 7.2, Guarantors hereby
jointly and severally agree, in furtherance of the foregoing and not in
limitation of any other right which any Beneficiary may have at law or in equity
against any Guarantor by virtue hereof, that upon the failure of the applicable
Borrower to pay any of the Guaranteed Obligations when and as the same shall
become due, whether at stated maturity, by required prepayment, declaration,
acceleration, demand or otherwise (including amounts that would become due but
for the operation of the automatic stay under Section 362(a) of the Bankruptcy
Code, 11 U.S.C.  (S) 362(a)), Guarantors will upon demand pay, or cause to be
paid, in Cash, to Administrative Agent for the ratable benefit of Beneficiaries,
an amount equal to the sum of the unpaid principal amount of all Guaranteed
Obligations then due as aforesaid, accrued and unpaid interest on such
Guaranteed Obligations (including interest which, but for the applicable
Borrower's becoming the subject of a case under the Bankruptcy code, would have
accrued on such Guaranteed Obligations, whether or not a claim is allowed
against the applicable Borrower for such interest in the related bankruptcy
case) and all other Guaranteed Obligations then owed to Beneficiaries as
aforesaid.

     7.4  Liability of Guarantors Absolute.  Each Guarantor agrees that its
obligations hereunder are irrevocable, absolute, independent and unconditional
and shall not be affected by any circumstance which constitutes a legal or
equitable discharge of a guarantor or surety other than payment in full of the
Guaranteed Obligations in Cash.  In furtherance of the foregoing and without
limiting the generality thereof, each Guarantor agrees as follows:

          (a) this Guaranty is a guaranty of payment when due and not of
collectability.  This Guaranty is a primary obligation of each Guarantor and not
merely a contract of surety;

          (b) Administrative Agent may enforce this Guaranty upon the occurrence
of an Event of Default notwithstanding the existence of any dispute between the
applicable Borrower and any Beneficiary with respect to the existence of such
Event of Default;

          (c) the obligations of each Guarantor hereunder are independent of the
obligations of the applicable Borrower and the obligations of any other
guarantor (including any other Guarantor) of the obligations of  the applicable
Borrower, and a separate action or actions may be brought and prosecuted against
such Guarantor whether or not any action is brought against the applicable
Borrower or any of such other guarantors and whether or not the applicable
Borrower is joined in any such action or actions;

          (d) payment by any Guarantor of a portion, but not all, of the
Guaranteed Obligations shall in no way limit, affect, modify or abridge any
Guarantor's liability for any portion of the Guaranteed Obligations which has
not been paid.  Without limiting the generality of the foregoing, if
Administrative Agent is awarded a judgment in any suit brought to enforce any
Guarantor's covenant to pay a portion of the Guaranteed Obligations, such
judgment shall not be deemed to release such Guarantor from its covenant to pay
the portion of the Guaranteed Obligations that is not the subject of such suit,
and such judgment shall not, except to the extent

                                      100
<PAGE>

satisfied by such Guarantor in Cash, limit, affect, modify or abridge any other
Guarantor's liability hereunder in respect of the Guaranteed Obligations;

          (e) any Beneficiary, upon such terms as it deems appropriate, without
notice or demand and without affecting the validity or enforceability hereof or
giving rise to any reduction, limitation, impairment, discharge or termination
of any Guarantor's liability hereunder, from time to time may (i) renew, extend,
accelerate, increase the rate of interest on, or otherwise change the time,
place, manner or terms of payment of the Guaranteed Obligations; (ii) settle,
compromise, release or discharge, or accept or refuse any offer of performance
with respect to, or substitutions for, the Guaranteed Obligations or any
agreement relating thereto and/or subordinate the payment of the same to the
payment of any other obligations; (iii) request and accept other guaranties of
the Guaranteed Obligations and take and hold security for the payment hereof or
the Guaranteed Obligations; (iv) release, surrender, exchange, substitute,
compromise, settle, rescind, waive, alter, subordinate or modify, with or
without consideration, any security for payment of the Guaranteed Obligations,
any other guaranties of the Guaranteed Obligations, or any other obligation of
any Person (including any other Guarantor) with respect to the Guaranteed
Obligations; (v) enforce and apply any security now or hereafter held by or for
the benefit of such Beneficiary in respect hereof or the Guaranteed Obligations
and direct the order or manner of sale thereof, or exercise any other right or
remedy that such Beneficiary may have against any such security, in each case as
such Beneficiary in its discretion may determine consistent herewith or the
applicable Hedge Agreement and any applicable security agreement, including
foreclosure on any such security pursuant to one or more judicial or nonjudicial
sales, whether or not every aspect of any such sale is commercially reasonable,
and even though such action operates to impair or extinguish any right of
reimbursement or subrogation or other right or remedy of any Guarantor against
the applicable Borrower or any security for the Guaranteed Obligations; and (vi)
exercise any other rights available to it under the Credit Documents or the
Hedge Agreements; and

          (f) this Guaranty and the obligations of Guarantors hereunder shall be
valid and enforceable and shall not be subject to any reduction, limitation,
impairment, discharge or termination for any reason (other than the indefeasible
payment in full of the Guaranteed Obligations in Cash), including the occurrence
of any of the following, whether or not any Guarantor shall have had notice or
knowledge of any of them: (i) any failure or omission to assert or enforce or
agreement or election not to assert or enforce, or the stay or enjoining, by
order of court, by operation of law or otherwise, of the exercise or enforcement
of, any claim or demand or any right, power or remedy (whether arising under the
Credit Documents or the Hedge Agreements, at law, in equity or otherwise) with
respect to the Guaranteed Obligations or any agreement relating thereto, or with
respect to any other guaranty of or security for the payment of the Guaranteed
Obligations; (ii) any rescission, waiver, amendment or modification of, or any
consent to departure from, any of the terms or provisions (including provisions
relating to events of default) hereof, any of the other Credit Documents, any of
the Hedge Agreements or any agreement or instrument executed pursuant thereto,
or of any other guaranty or security for the Guaranteed Obligations, in each
case whether or not in accordance with the terms hereof or such Credit Document,
such Hedge Agreement or any agreement relating to such other guaranty or
security; (iii) the Guaranteed Obligations, or any agreement relating thereto,
at any time being found to be illegal, invalid or unenforceable in any respect;
(iv) the application of payments received from any source (other than payments
received pursuant to the other Credit Documents

                                      101
<PAGE>

or any of the Hedge Agreements or from the proceeds of any security for the
Guaranteed Obligations, except to the extent such security also serves as

or any of its Subsidiaries and to any corresponding restructuring of the

Obligations or any other Person,  proceed against or exhaust any security held

or any disability or other defense of the applicable Borrower or any other
Guarantor including any defense based on or arising out of the lack of validity
or the unenforceability of the Guaranteed Obligations or any agreement or
instrument relating thereto or by reason of the cessation of the liability of
the applicable Borrower or any other Guarantor from any cause other than payment

     7.6  Guarantors' Rights of Subrogation, Contribution, etc.  Until the
Guaranteed Obligations shall have been indefeasibly paid in full and all
Commitments shall have terminated and all Letters of Credit shall have expired
or been cancelled, each Guarantor hereby waives any claim, right or remedy,
direct or indirect, that such Guarantor now has or may hereafter have against
the applicable Borrower or any other Guarantor or any of its assets in
connection with this Guaranty or the performance by such Guarantor of its
obligations hereunder, in each case whether such claim, right or remedy arises
in equity, under contract, by statute, under common law or otherwise and
including without limitation  any right of subrogation, reimbursement or
indemnification that such Guarantor now has or may hereafter have against the
applicable Borrower with respect to the Guaranteed Obligations,  any right to
enforce, or to participate in, any claim, right or remedy that any Beneficiary
now has or may hereafter have against the applicable Borrower, and  any benefit
of, and any right to participate in, any collateral or security now or hereafter
held by any Beneficiary.  In addition, until the Guaranteed Obligations shall
have been indefeasibly paid in full in Cash and the Commitments shall have
terminated and all Letters of Credit shall have expired or been cancelled, each
Guarantor shall withhold exercise of any right of contribution such Guarantor
may have against any other guarantor (including any other Guarantor) of the
Guaranteed Obligations, including, without limitation, any such right of
contribution as contemplated by Section 7.2.  Each Guarantor further agrees
that, to the extent the waiver or agreement to withhold the exercise of its
rights of subrogation, reimbursement, indemnification and contribution as set
forth herein is found by a court of competent jurisdiction to be void or
voidable for any reason, any rights of subrogation, reimbursement or
indemnification such Guarantor may have against the applicable Borrower or
against any collateral or security, and any rights of contribution such
Guarantor may have against any such other guarantor, shall be junior and
subordinate to any rights any Beneficiary may have against the applicable
Borrower, to all right, title and interest any Beneficiary may have in any such
collateral or security, and to any right any Beneficiary may have against such
other guarantor.  If any amount shall be paid to any Guarantor on account of any
such subrogation, reimbursement, indemnification or contribution rights at any
time when all Guaranteed Obligations shall not have been finally and
indefeasibly paid in full in Cash, such amount shall be held in trust for
Administrative Agent on behalf of Beneficiaries and shall forthwith be paid over
to Administrative Agent for the benefit of Beneficiaries to be credited and
applied against the Guaranteed Obligations, whether matured or unmatured, in
accordance with the terms hereof.

     7.7  Subordination of Other Obligations.  Any Indebtedness of any Borrower
or any Guarantor now or hereafter held by any Guarantor (the "Obligee
Guarantor") is hereby subordinated in right of payment to the Guaranteed
Obligations, and any such indebtedness collected or received by the Obligee
Guarantor after an Event of Default has occurred and is continuing shall be held
in trust for Administrative Agent on behalf of Beneficiaries and shall forthwith
be paid over to Administrative Agent for the benefit of Beneficiaries to be
credited and applied against the Guaranteed Obligations but without affecting,
impairing or limiting in any manner the liability of the Obligee Guarantor under
any other provision hereof.

     7.8  Continuing Guaranty.  This Guaranty is a continuing guaranty and shall
remain in effect until all of the Guaranteed Obligations shall have been finally
and indefeasibly paid in full in Cash and the Revolving Loan Commitments shall
have terminated and all Letters of Credit shall have expired or been cancelled.
Each Guarantor hereby irrevocably waives any right to revoke this Guaranty as to
future transactions giving rise to any Guaranteed Obligations.

                                      103
<PAGE>

     7.9  Authority of Guarantors or Borrower.  It is not necessary for any
Beneficiary to inquire into the capacity or powers of any Guarantor or the
applicable Borrower or the officers, directors or any agents acting or
purporting to act on behalf of any of them.

     7.10 Financial Condition of Borrower.  Any Credit Extension may be made to
a Borrower or continued from time to time, and any Hedge Agreements may be
entered into from time to time, in each case without notice to or authorization
from any Guarantor regardless of the financial or other condition of Company at
the time of any such grant or continuation or at the time such Hedge Agreement
is entered into, as the case may be.  No Beneficiary shall have any obligation
to disclose or discuss with any Guarantor its assessment, or any Guarantor's
assessment, of the financial condition of the applicable Borrower.  Each
Guarantor has adequate means to obtain information from the applicable Borrower
on a continuing basis concerning the financial condition of the applicable
Borrower and its ability to perform its obligations under the Credit Documents
and the Hedge Agreements, and each Guarantor assumes the responsibility for
being and keeping informed of the financial condition of the applicable Borrower
and of all circumstances bearing upon the risk of nonpayment of the Guaranteed
Obligations.  Each Guarantor hereby waives and relinquishes any duty on the part
of any Beneficiary to disclose any matter, fact or thing relating to the
business, operations or conditions of the applicable Borrower now known or
hereafter known by any Beneficiary.

     7.11 Bankruptcy, etc.  So long as any Guaranteed Obligations remain
outstanding, no Guarantor shall, without the prior written consent of
Administrative Agent acting pursuant to the instructions of Requisite Lenders,
commence or join with any other Person in commencing any bankruptcy,
reorganization or insolvency case or proceeding of or against the applicable
Borrower or any other Guarantor.  The obligations of Guarantors hereunder shall
not be reduced, limited, impaired, discharged, deferred, suspended or terminated
by any case or proceeding, voluntary or involuntary, involving the bankruptcy,
insolvency, receivership, reorganization, liquidation or arrangement of the
applicable Borrower or any other Guarantor or by any defense which the
applicable Borrower or any other Guarantor may have by reason of the order,
decree or decision of any court or administrative body resulting from any such
proceeding.

          (a) Each Guarantor acknowledges and agrees that any interest on any
portion of the Guaranteed Obligations which accrues after the commencement of
any case or proceeding referred to in clause (a) above (or, if interest on any
portion of the Guaranteed Obligations ceases to accrue by operation of law by
reason of the commencement of such case or proceeding, such interest as would
have accrued on such portion of the Guaranteed Obligations if such case or
proceeding had not been commenced) shall be included in the Guaranteed
Obligations because it is the intention of Guarantors and Beneficiaries that the
Guaranteed Obligations which are guaranteed by Guarantors pursuant hereto should
be determined without regard to any rule of law or order which may relieve the
applicable Borrower of any portion of such Guaranteed Obligations.  Guarantors
will permit any trustee in bankruptcy, receiver, debtor in possession, assignee
for the benefit of creditors or similar person to pay Administrative Agent, or
allow the claim of Administrative Agent in respect of, any such interest
accruing after the date on which such case or proceeding is commenced.

          (b) In the event that all or any portion of the Guaranteed Obligations
are paid by the applicable Borrower, the obligations of Guarantors hereunder
shall continue and remain in

                                      104
<PAGE>

full force and effect or be reinstated, as the case may be, in the event that
all or any part of such payment(s) are rescinded or recovered directly or
indirectly from any Beneficiary as a preference, fraudulent transfer or
otherwise (whether by demand, settlement, litigation or otherwise), and any such
payments which are so rescinded or recovered shall constitute Guaranteed
Obligations for all purposes hereunder.

     7.12 Notice of Events.  As soon as any Guarantor obtains knowledge thereof,
such Guarantor shall give Administrative Agent written notice of any condition
or event which has resulted in a material adverse change in the financial
conditions of any Guarantor or the applicable Borrower or a breach of or
noncompliance with any term, condition or covenant contained herein, any other
Credit  Document, any Hedge Agreement or any other document delivered pursuant
hereto or thereto.

     7.13 Discharge of Guaranty Upon Sale of Guarantor.  If all of the Capital
Stock of any Guarantor or any of its successors in interest hereunder shall be
sold or otherwise disposed of (including by merger or consolidation) in
accordance with the terms and conditions hereof, the Guaranty of such Guarantor
or such successor in interest, as the case may be, hereunder shall automatically
be discharged and released without any further action by any Beneficiary or any
other Person effective as of the time of such Asset Sale; provided, as a
                                                          --------
condition precedent to such discharge and release, Administrative Agent shall
have received evidence satisfactory to it that arrangements satisfactory to it
have been made for delivery to Administrative Agent of the applicable Net Asset
Sale Proceeds of such disposition pursuant to Section 2.12(a).

     9.4  Agents Entitled to Act as Lender.  The agency hereby created shall in
no way impair or affect any of the rights and powers of, or impose any duties or
obligations upon, any Agent in its individual capacity as a Lender hereunder.
With respect to its participation in the Loans and the Letters of Credit, each
Agent, in its individual capacity, shall have the same rights and powers
hereunder as any other Lender and may exercise the same as if it were not
performing the duties and functions delegated to it hereunder, and the term
"Lender" shall, unless the context clearly otherwise indicates, include each
Agent in its individual capacity.  Any Agent, in its individual capacity, and
its Affiliates may accept deposits from, lend money to and generally engage in
any kind of banking, trust, financial advisory or other business with either
Borrower or any of its Affiliates as if it were not performing the duties
specified herein, and may accept fees and other consideration from either
Borrower for services in connection herewith and otherwise without having to
account for the same to Lenders.

     9.5  Lenders' Representations, Warranties and Acknowledgment.  Each Lender
represents and warrants that it has made its own independent investigation of
the financial condition and affairs of Company and its Subsidiaries in
connection with Credit Extensions hereunder and that it has made and shall
continue to make its own appraisal of the creditworthiness of Company and its
Subsidiaries.  No Agent shall have any duty or responsibility, either initially
or on a continuing basis, to make any such investigation or any such appraisal
on behalf of Lenders or to provide any Lender with any credit or other
information with respect thereto, whether coming into its possession before the
making of the Loans or at any time or times thereafter, and no Agent shall have
any responsibility with respect to the accuracy of or the completeness of any
information provided to Lenders.

     9.6  Right to Indemnity.  Each Lender, in proportion to its Pro Rata Share,
severally agrees to indemnify each Agent, to the extent that such Agent shall
not have been reimbursed by any Credit Party, for and against any and all
liabilities, obligations, losses, damages, penalties, actions, judgments, suits,
costs, expenses (including reasonable counsel fees and disbursements) or
disbursements of any kind or nature whatsoever which may be imposed on, incurred
by or asserted against such Agent in exercising its powers, rights and remedies
or performing its duties hereunder or under the other Credit Documents or
otherwise in its capacity as such Agent in any

                                      110
<PAGE>

way relating to or arising out hereof or the other Credit Documents; provided,
                                                                     --------
no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from such Agent's gross negligence or willful
misconduct. If any indemnity furnished to any Agent for any purpose shall, in
the opinion of such Agent, be insufficient or become impaired, such Agent may
call for additional indemnity and cease, or not commence, to do the acts
indemnified against until such additional indemnity is furnished; provided, in
                                                                  --------
no event shall this sentence require any Lender to indemnify any Agent against
any liability, obligation, loss, damage, penalty, action, judgment, suit, cost,
expense or disbursement in excess of such Lender's Pro Rata Share thereof; and
provided further, this sentence shall not be deemed to require any Lender to
-------- -------
indemnify any Agent against any liability, obligation, loss, damage, penalty,
action, judgment, suit, cost, expense or disbursement described in the proviso
in the immediately preceding sentence.

assigned to it pursuant to such Assignment Agreement and shall thereafter be a
party hereto and a "Lender" for all purposes hereof;  the assigning Lender
thereunder shall, to the extent that rights and obligations hereunder have been
assigned thereby pursuant to such Assignment Agreement, relinquish its rights
(other than any rights which survive the termination hereof under Section 10.8)
and be released from its obligations hereunder (and, in the case of an
Assignment Agreement covering all or the remaining portion of an assigning
Lender's rights and obligations hereunder, such Lender shall cease to be a party
hereto; provided, anything contained in any of the Credit Documents to the
        --------
contrary notwithstanding, (y) Issuing Bank shall continue to have all rights and
obligations thereof with respect to such Letters of Credit until the
cancellation or expiration of such Letters of Credit and the reimbursement of
any amounts drawn thereunder) and (z) such assigning Lender shall continue to be
entitled to the benefit of all indemnities hereunder as specified herein with
respect to matters arising out of the prior involvement of such assigning Lender
as a Lender hereunder;  the Revolving Loan Commitments shall be modified to
reflect the Revolving Loan Commitment of such assignee and any remaining
Revolving Loan Commitment of such assigning Lender, if any; (i) the Delayed Draw
Term Loan Commitments shall be modified to reflect the Delayed Draw Term Loan
Commitment of such assignee and any remaining Delayed Draw Term Loan Commitment
of such assigning Lender, if any; and (ii) if any such assignment occurs after
the issuance of any Note hereunder, the assigning Lender shall, upon the
effectiveness of such assignment or as promptly thereafter as practicable,
surrender its applicable Notes to Administrative Agent for cancellation, and
thereupon the applicable Borrower or Borrowers shall issue and deliver new
Notes, if so requested by the assignee and/or assigning Lender, to such assignee
and/or to such assigning Lender, with appropriate insertions, to reflect the new
Commitments and/or outstanding Loans of the assignee and/or the assigning
Lender.

          (h) Participations.  Each Lender shall have the right at any time to
              --------------
sell one or more participations to any Person (other than Company, any of its
Subsidiaries or any of its

                                      118
<PAGE>

Affiliates) in all or any part of its Commitments, Loans or in any other
Obligation. The holder of any such participation, other than an Affiliate of the
Lender granting such participation, shall not be entitled to require such Lender
to take or omit to take any action hereunder except with respect to any
amendment modification or waiver that would (i) extend the final scheduled
maturity of any Loan, Note or Letter of Credit (unless such Letter of Credit is
not extended beyond the Revolving Loan Commitment Termination Date) in which
such participant is participating, or reduce the rate or extend the time of
payment of interest or fees thereon (except in connection with a waiver of
applicability of any postdefault increase in interest rates) or reduce the
principal amount thereof, or increase the amount of the participant's
participation over the amount thereof then in effect (it being understood that a
waiver of any Default or Event of Default or of a mandatory reduction in the
Commitment shall not constitute a change in the terms of such participation, and
that an increase in any Commitment or Loan shall be permitted without the
consent of any participant if the participant's participation is not increased
as a result thereof), (ii) consent to the assignment or transfer by any Credit
Party of any of its rights and obligations under this Agreement or (iii) release
or subordinate all or substantially all of the Collateral under the Collateral
Documents or the Guarantors (except as expressly provided in the Credit
Documents) supporting the Loans hereunder in which such participant is
participating. All amounts payable by any Credit Party hereunder, including
amounts payable to such Lender pursuant to Section 2.17(c), 2.18 or 2.19, shall
be determined as if such Lender had not sold such participation. Each Credit
Party and each Lender hereby acknowledge and agree that, solely for purposes of
Sections 2.16 and 10.4, any participation will give rise to a direct obligation
of each Credit Party to the participant and the participant shall be considered
to be a "Lender."

          (i) Certain Other Assignments.  In addition to any other assignment
              -------------------------
permitted pursuant to this Section 10.6, (i) any Lender may assign and pledge
all or any portion of its Loans, the other Obligations owed to such Lender, and
its Notes, if any, to secure obligations of such Lender, including, without
limitation, any pledge or assignment to secure obligations to any Federal
Reserve Bank or as collateral security for any loan or other financing
transaction as in or in connection with any securitization or similar
transaction, and this Section 10.6 shall not apply to any such pledge or
assignment of a security interest or other transaction described herein;
provided, (x) no Lender, as between the applicable Borrower or Borrowers and
--------
such Lender, shall be relieved of any of its obligations hereunder as a result
of any such assignment and pledge, and provided further, (y) in no event shall
                                       -------- -------
the applicable Federal Reserve Bank or trustee or other financing party be
considered to be a "Lender" or be entitled to require the assigning Lender to
take or omit to take any action hereunder and (z) any transfer of the rights and
obligations of a "Lender" hereunder to any Person upon the foreclosure of any
pledge or security interest referred to in this clause (i) may only be made
pursuant to the provisions of Sections 10.6(c) through (e) governing assignments
of interests in the Loans.

     10.7 Independence of Covenants.  All covenants hereunder shall be given
independent effect so that if a particular action or condition is not permitted
by any of such covenants, the fact that it would be permitted by an exception
to, or would otherwise be within the limitations of, another covenant shall not
avoid the occurrence of a Default or an Event of Default if such action is taken
or condition exists.

     10.8 Survival of Representations, Warranties and Agreements.  All
representations, warranties and agreements made herein shall survive the
execution and delivery

                                      119
<PAGE>

hereof and the making of any Credit Extension. Notwithstanding anything herein
or implied by law to the contrary, the agreements of each Credit Party set forth
in Sections 2.17(c), 2.18, 2.19, 10.2, 10.3 and 10.4 and the agreements of
Lenders set forth in Sections 2.16 and 9.6 shall survive the payment of the
Loans, the cancellation or expiration of the Letters of Credit and the
reimbursement of any amounts drawn thereunder, and the termination hereof.

     10.9 No Waiver; Remedies Cumulative.  No failure or delay on the part of
any Agent or any Lender in the exercise of any power, right or privilege
hereunder or under any other Credit Document shall impair such power, right or
privilege or be construed to be a waiver of any default or acquiescence therein,
nor shall any single or partial exercise of any such power, right or privilege
preclude other or further exercise thereof or of any other power, right or
privilege.  The rights, powers and remedies given to each Agent and each Lender
hereby are cumulative and shall be in addition to and independent of all rights,
powers and remedies existing by virtue of any statute or rule of law or in any
of the other Credit Documents or any of the Hedge Agreements.  Any forbearance
or failure to exercise, and any delay in exercising, any right, power or remedy
hereunder shall not impair any such right, power or remedy or be construed to be
a waiver thereof, nor shall it preclude the further exercise of any such right,
power or remedy.

     10.10 Marshalling; Payments Set Aside.  Neither any Agent nor any Lender
shall be under any obligation to marshal any assets in favor of any Credit Party
or any other Person or against or in payment of any or all of the Obligations.
To the extent that any Credit Party makes a payment or payments to
Administrative Agent or Lenders (or to Administrative Agent, on behalf of
Lenders), or Collateral Agent, Administrative Agent or Lenders enforce any
security interests or exercise their rights of setoff, and such payment or
payments or the proceeds of such enforcement or setoff or any part thereof are
subsequently invalidated, declared to be fraudulent or preferential, set aside
and/or required to be repaid to a trustee, receiver or any other party under any
bankruptcy law, any other state or federal law, common law or any equitable
cause (whether by demand, settlement, litigation or otherwise), then, to the
extent of such recovery, the obligation or part thereof originally intended to
be satisfied, and all Liens, rights and remedies therefor or related thereto,
shall be revived and continued in full force and effect as if such payment or
payments had not been made or such enforcement or setoff had not occurred.

     10.11 Severability. In case any Note shall be invalid, illegal or
unenforceable in any jurisdiction, the validity, legality and enforceability of
the remaining provisions or obligations, or of such provision or obligation in
any other jurisdiction, shall not in any way be affected or impaired thereby.

     10.12  Entire Agreement.  This Agreement (together with the Exhibits
hereto, the Schedules hereto and the other agreements, documents and instruments
delivered in connection herewith) and the Credit Documents constitute the entire
agreement among the parties with respect to the subject matter hereof and
thereof and supersede all other prior agreements and understandings, both
written and verbal, among the parties or any of them with respect to the subject
matter hereof.

     10.13 Obligations Several; Independent Nature of Lenders' Rights.  The
obligations of Lenders hereunder are several and no Lender shall be responsible
for the obligations or

                                      120
<PAGE>

Commitment of any other Lender hereunder. Nothing contained herein or in any
other Credit Document, and no action taken by Lenders pursuant hereto or
thereto, shall be deemed to constitute Lenders as a partnership, an association,
a joint venture or any other kind of entity. The amounts payable at any time
hereunder to each Lender shall be a separate and independent debt, and each
Lender shall be entitled to protect and enforce its rights arising hereunder and
it shall not be necessary for any other Lender to be joined as an additional
party in any proceeding for such purpose.

     10.14 Headings.  Section headings herein are included herein for
convenience of reference only and shall not constitute a part hereof for any
other purpose or be given any substantive effect.

     10.15 APPLICABLE LAW.  THIS AGREEMENT AND THE RIGHTS AND OBLIGATIONS OF
THE PARTIES HEREUNDER SHALL BE GOVERNED BY, AND SHALL BE CONSTRUED AND ENFORCED
IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK (INCLUDING SECTION 5-1401,
SECTION 5-1402 OF THE GENERAL OBLIGATIONS LAW OF THE STATE OF NEW YORK) WITHOUT
REGARD TO CONFLICTS OF LAWS PRINCIPLES THEREOF.

     10.16 CONSENT TO JURISDICTION.  ALL JUDICIAL PROCEEDINGS BROUGHT AGAINST
ANY CREDIT PARTY ARISING OUT OF OR RELATING HERETO OR ANY OTHER CREDIT DOCUMENT,
OR ANY OF THE OBLIGATIONS, MAY BE BROUGHT IN ANY STATE OR FEDERAL COURT OF
COMPETENT JURISDICTION IN THE STATE, COUNTY AND CITY OF NEW YORK.  BY EXECUTING
AND DELIVERING THIS AGREEMENT, EACH CREDIT PARTY, FOR ITSELF AND IN CONNECTION
WITH ITS PROPERTIES, IRREVOCABLY  ACCEPTS GENERALLY AND UNCONDITIONALLY THE
NONEXCLUSIVE JURISDICTION AND VENUE OF SUCH COURTS;  WAIVES ANY DEFENSE OF FORUM
NON CONVENIENS;  AGREES THAT SERVICE OF ALL PROCESS IN ANY SUCH PROCEEDING IN
ANY SUCH COURT MAY BE MADE BY REGISTERED OR CERTIFIED MAIL, RETURN RECEIPT
REQUESTED, TO THE APPLICABLE CREDIT PARTY AT ITS ADDRESS PROVIDED IN ACCORDANCE
WITH SECTION 10.1;  AGREES THAT SERVICE AS PROVIDED IN CLAUSE (c) ABOVE IS
SUFFICIENT TO CONFER PERSONAL JURISDICTION OVER THE APPLICABLE CREDIT PARTY IN
ANY SUCH PROCEEDING IN ANY SUCH COURT, AND OTHERWISE CONSTITUTES EFFECTIVE AND
BINDING SERVICE IN EVERY RESPECT; AND  AGREES AGENTS AND LENDERS RETAIN THE
RIGHT TO SERVE PROCESS IN ANY OTHER MANNER PERMITTED BY LAW OR TO BRING
PROCEEDINGS AGAINST ANY CREDIT PARTY IN THE COURTS OF ANY OTHER JURISDICTION.

     10.17 WAIVER OF JURY TRIAL.  EACH OF THE PARTIES HERETO HEREBY AGREES TO
WAIVE ITS RESPECTIVE RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION
BASED UPON OR ARISING HEREUNDER OR UNDER ANY OF THE OTHER CREDIT DOCUMENTS OR
ANY DEALINGS BETWEEN THEM RELATING TO THE SUBJECT MATTER OF THIS LOAN
TRANSACTION OR THE LENDER/BORROWER RELATIONSHIP THAT IS BEING ESTABLISHED.  THE
SCOPE OF THIS WAIVER IS INTENDED TO BE ALLENCOMPASSING OF ANY AND ALL

                                      121
<PAGE>

DISPUTES THAT MAY BE FILED IN ANY COURT AND THAT RELATE TO THE SUBJECT MATTER OF
THIS TRANSACTION, INCLUDING CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS
AND ALL OTHER COMMON LAW AND STATUTORY CLAIMS. EACH PARTY HERETO ACKNOWLEDGES
THAT THIS WAIVER IS A MATERIAL INDUCEMENT TO ENTER INTO A BUSINESS RELATIONSHIP,
THAT EACH HAS ALREADY RELIED ON THIS WAIVER IN ENTERING INTO THIS AGREEMENT, AND
THAT EACH WILL CONTINUE TO RELY ON THIS WAIVER IN ITS RELATED FUTURE DEALINGS.
EACH PARTY HERETO FURTHER WARRANTS AND REPRESENTS THAT IT HAS REVIEWED THIS
WAIVER WITH ITS LEGAL COUNSEL AND THAT IT KNOWINGLY AND VOLUNTARILY WAIVES ITS
JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. THIS WAIVER IS
IRREVOCABLE, MEANING THAT IT MAY NOT BE MODIFIED EITHER ORALLY OR IN WRITING
(OTHER THAN BY A MUTUAL WRITTEN WAIVER SPECIFICALLY REFERRING TO THIS SECTION
10.17 AND EXECUTED BY EACH OF THE PARTIES HERETO), AND THIS WAIVER SHALL APPLY
TO ANY SUBSEQUENT AMENDMENTS, RENEWALS, SUPPLEMENTS OR MODIFICATIONS HERETO OR
ANY OF THE OTHER CREDIT DOCUMENTS OR TO ANY OTHER DOCUMENTS OR AGREEMENTS
RELATING TO THE LOANS MADE HEREUNDER. IN THE EVENT OF LITIGATION, THIS AGREEMENT
MAY BE FILED AS A WRITTEN CONSENT TO A TRIAL BY THE COURT.

     10.18  Confidentiality.  Each Lender shall hold all nonpublic information
obtained pursuant to the requirements hereof and sufficiently identified to such
Lender as being non-public which has been identified as confidential by either
Borrower in accordance with such Lender's customary procedures for handling
confidential information of this nature and in accordance with prudent lending
or investing practices, it being understood and agreed by each Borrower that in
any event a Lender may make disclosures to Affiliates of such Lender (and to
other persons authorized by a Lender or Agent to organize, present or
disseminate such information in connection with disclosures otherwise made in
accordance with this Section 10.18), disclosures reasonably required by any bona
fide or potential assignee, transferee or participant in connection with the
contemplated assignment, transfer or participation by such Lender of any Loans
Commitments and other Obligations or any participations therein or by any direct
or indirect contractual counterparties (or the professional advisors thereto) in
Hedge Agreements (provided, such counterparties and advisors are advised of and
agree to be bound by the provisions of this Section 10.18) or disclosures
required or requested by any governmental agency or representative thereof or by
the NAIC or pursuant to legal process; provided, unless specifically prohibited
                                       --------
by applicable law or court order, each Lender shall make reasonable efforts to
notify the applicable Borrower of any request by any governmental agency or
representative thereof (other than any such request in connection with any
examination of the financial condition or other routine examination of such
Lender by such governmental agency) for disclosure of any such nonpublic
information prior to disclosure of such information; provided, further, that in
                                                     --------  -------
no event shall any Lender be obligated or required to return any materials
furnished by Company or any of its Subsidiaries; and provided, further, that
                                                     --------  -------
notwithstanding the foregoing, each Lender and its Affiliates shall have the
right to (i) list the name and logo of each of the Borrowers and the Guarantors,
as provided by the Borrowers and the Guarantors from time to time, and describe
the transaction that is the subject of this

                                      122
<PAGE>

Agreement in their marketing materials and (ii) post such information,
including, without limitation, a customary "tombstone", on its web site.

     10.19 Usury Savings Clause.  Notwithstanding any other provision herein,
the aggregate interest rate charged with respect to any of the Obligations,
including all charges or fees in connection therewith deemed in the nature of
interest under applicable law shall not exceed the Highest Lawful Rate.  If the
rate of interest (determined without regard to the preceding sentence) under
this Agreement at any time exceeds the Highest Lawful Rate, the outstanding
amount of the Loans made hereunder shall bear interest at the Highest Lawful
Rate until the total amount of interest due hereunder equals the amount of
interest which would have been due hereunder if the stated rates of interest set
forth in this Agreement had at all times been in effect.  In addition, if when
the Loans made hereunder are repaid in full the total interest due hereunder
(taking into account the increase provided for above) is less than the total
amount of interest which would have been due hereunder if the stated rates of
interest set forth in this Agreement had at all times been in effect, then to
the extent permitted by law, the applicable Borrower shall pay to Administrative
Agent, for the account of the Lenders, an amount equal to the difference between
the amount of interest paid and the amount of interest which would have been
paid if the Highest Lawful Rate had at all times been in effect.
Notwithstanding the foregoing, it is the intention of Lenders and each Borrower
to conform strictly to any applicable usury laws.  Accordingly, if any Lender
contracts for, charges, or receives any consideration which constitutes interest
in excess of the Highest Lawful Rate, then any such excess shall be cancelled
automatically and, if previously paid, shall at such Lender's option be applied
to the outstanding amount of the Loans made hereunder or be refunded to the
applicable Borrower.

     10.20 Counterparts.  This Agreement may be executed in any number of
counterparts, each of which when so executed and delivered shall be deemed an
original, but all such counterparts together shall constitute but one and the
same instrument.

     10.21 Effectiveness.  This Agreement shall become effective upon the
execution of a counterpart hereof by each of the parties hereto and receipt by
Company and Administrative Agent of written or telephonic notification of such
execution and authorization of delivery thereof.
