          2.02  Borrowings.  The Borrower shall give the Administrative Agent
                ----------                                                   
notice of each borrowing hereunder as provided in Section 4.05 hereof.  Not
later than 1:00 p.m. New York time on the date specified for each borrowing
hereunder, each Lender shall make available the amount of the Loan or Loans to
be made by it on such date to the Administrative Agent at the Principal Office,
in immediately available funds, for account of the Borrower.  The amount so
received by the Administrative Agent shall, subject to the terms and conditions
of this Agreement, be made available to the Borrower by depositing the same, in
immediately available funds, in an account of the Borrower designated by the
Borrower and maintained with the Administrative Agent at the office of the
Administrative Agent specified in Section 12.02 hereof.

          2.03  Letters of Credit.  Subject to the terms and conditions of this
                -----------------                                              
Agreement, the Revolving Credit Commitments may be utilized, upon the request of
the Borrower, in addition to the Revolving Credit Loans provided for by Section
2.01(a) hereof, by the issuance by the Issuing Lender of letters of credit
(collectively, "Letters of Credit") for account of the Borrower or any of its
                -----------------                                            
Subsidiaries (as specified by the Borrower), provided that in no event shall (i)
                                             --------                           
the aggregate amount of all Letter of Credit Liabilities, together with the
aggregate principal amount of the Revolving Credit Loans, exceed the aggregate
amount of the Revolving Credit Commitments as in effect from time to time, (ii)
the outstanding aggregate amount of all Letter of Credit Liabilities exceed
$3,000,000 and (iii) the expiration date of any Letter of Credit extend beyond
the earlier of five Business Days prior to the Revolving Credit Commitment
Termination Date and the date twelve months following the issuance of such
Letter of Credit.  Letters of Credit issued under the Existing Credit Agreement
which are outstanding on the Amendment/Restatement Effective Date shall be
deemed to be Letters of Credit issued under this Agreement on the
Amendment/Restatement Effective Date.  The following additional provisions shall
apply to Letters of Credit:

          (a)  The Borrower shall give the Administrative Agent at least three
     Business Days' irrevocable prior notice (effective upon receipt) specifying
     the Business Day (which shall be no later than 30 days preceding the
     Revolving Credit Commitment Termination Date) each Letter of Credit is to
     be issued and the account party or parties therefor and describing in
     reasonable detail the proposed terms of such Letter of Credit (including
     the beneficiary thereof) and the nature of the transactions or obligations
     proposed to be supported thereby (including whether such Letter of Credit
     is to be a commercial letter of credit or a standby letter of credit).
     Upon receipt of any such notice, the Administrative Agent shall advise the
     Issuing Lender of the contents thereof.

          (b)  On each day during the period commencing with the issuance by the
     Issuing Lender of any Letter of Credit and until such Letter of Credit
     shall have expired or been terminated, the Revolving Credit Commitment of
     each Revolving Credit Lender shall be deemed to be utilized for all
     purposes of this Agreement in an amount equal to such Lender's Revolving
     Credit Commitment Percentage of the then undrawn face amount of such Letter
     of Credit.  Each Revolving Credit Lender (other than the Issuing Lender)
     agrees that, upon the issuance of any Letter of Credit hereunder, it shall
     automatically acquire a participation in the Issuing Lender's liability
     under such Letter of Credit in an amount equal to such Lender's Revolving
     Credit Commitment Percentage of such liability, and each Revolving Credit
     Lender (other than the Issuing Lender) thereby shall absolutely,
     unconditionally and irrevocably assume, as primary obligor and not as
     surety, and shall be unconditionally obligated to the Issuing Lender to pay
     and discharge when due, its Revolving Credit Commitment Percentage of the
     Issuing Lender's liability under such Letter of Credit.

          (c)  Upon receipt from the beneficiary of any Letter of Credit of any
     demand for payment under such Letter of Credit, the Issuing Lender shall
     promptly notify the Borrower (through the Administrative Agent) of the
     amount to be paid by the Issuing Lender as a result of 

 
                                                                              23

     such demand and the date on which payment is to be made by the Issuing
     Lender to such beneficiary in respect of such demand. Notwithstanding the
     identity of the account party of any Letter of Credit, the Borrower hereby
     unconditionally agrees to pay and reimburse the Administrative Agent for
     account of the Issuing Lender for the amount of each demand for payment
     under such Letter of Credit that is in substantial compliance with the
     provisions of such Letter of Credit at or prior to the date on which
     payment is to be made by the Issuing Lender to the beneficiary thereunder,
     without presentment, demand, protest or other formalities of any kind.

          (d)  Forthwith upon its receipt of a notice referred to in paragraph
     (c) of this Section 2.03, the Borrower shall advise the Administrative
     Agent whether or not the Borrower intends to borrow hereunder to finance
     its obligation to reimburse the Issuing Lender for the amount of the
     related demand for payment and, if it does, submit a notice of such
     borrowing as provided in Section 4.05 hereof.

          (e)  Each Revolving Credit Lender (other than the Issuing Lender)
     shall pay to the Administrative Agent for account of the Issuing Lender at
     the Principal Office in Dollars and in immediately available funds, the
     amount of such Lender's Revolving Credit Commitment Percentage of any
     payment under a Letter of Credit upon notice by the Issuing Lender (through
     the Administrative Agent) to such Revolving Credit Lender requesting such
     payment and specifying such amount.  Each such Revolving Credit Lender's
     obligation to make such payment to the Administrative Agent for account of
     the Issuing Lender under this paragraph (e), and the Issuing Lender's right
     to receive the same, shall be absolute and unconditional and shall not be
     affected by any circumstance whatsoever, including, without limitation, the
     failure of any other Revolving Credit Lender to make its payment under this
     paragraph (e), the financial condition of the Borrower (or any other
     account party), the existence of any Default or the termination of the
     Commitments.  Each such payment to the Issuing Lender shall be made without
     any offset, abatement, withholding or reduction whatsoever.  If any
     Revolving Credit Lender shall default in its obligation to make any such
     payment to the Administrative Agent for account of the Issuing Lender, for
     so long as such default shall continue the Administrative Agent may at the
     request of the Issuing Lender withhold from any payments received by the
     Administrative Agent under this Agreement or any Note for account of such
     Revolving Credit Lender the amount so in default and, to the extent so
     withheld, pay the same to the Issuing Lender in satisfaction of such
     defaulted obligation.

          (f)  Upon the making of each payment by a Revolving Credit Lender to
     the Issuing Lender pursuant to paragraph (e) above in respect of any Letter
     of Credit, such Lender shall, automatically and without any further action
     on the part of the Administrative Agent, the Issuing Lender or such Lender,
     acquire (i) a participation in an amount equal to such payment in the
     Reimbursement Obligation owing to the Issuing Lender by the Borrower
     hereunder and under the Letter of Credit Documents relating to such Letter
     of Credit and (ii) a participation in a percentage equal to such Lender's
     Revolving Credit Commitment Percentage in any interest or other amounts
     payable by the Borrower hereunder and under such Letter of Credit Documents
     in respect of such Reimbursement Obligation (other than the commissions,
     charges, costs and expenses payable to the Issuing Lender pursuant to
     paragraph (g) of this Section 2.03).  Upon receipt by the Issuing Lender
     from or for account of the Borrower of any payment in respect of any
     Reimbursement Obligation or any such interest or other amount (including by
     way of setoff or application of proceeds of any collateral security) the
     Issuing Lender shall promptly pay to the Administrative Agent for account
     of each Revolving Credit Lender entitled thereto, such Revolving Credit
     Lender's Revolving Credit Commitment Percentage of such payment, each such
     payment by the Issuing Lender to be made in the same money and funds in
     which received 

 
                                                                              24

     by the Issuing Lender. In the event any payment received by the Issuing
     Lender and so paid to the Revolving Credit Lenders hereunder is rescinded
     or must otherwise be returned by the Issuing Lender, each Revolving Credit
     Lender shall, upon the request of the Issuing Lender (through the
     Administrative Agent), repay to the Issuing Lender (through the
     Administrative Agent) the amount of such payment paid to such Lender, with
     interest at the rate specified in paragraph (j) of this Section 2.03.

          (g)  The Borrower shall pay to the Administrative Agent for account of
     each Revolving Credit Lender (ratably in accordance with their respective
     Revolving Credit Commitment Percentages) a letter of credit fee on the
     daily average undrawn face amount of such Letter of Credit at a rate per
     annum equal to the Applicable Margin for Revolving Credit Loans that are
     Eurodollar Loans for the period from and including the date of issuance of
     such Letter of Credit (i) in the case of a Letter of Credit that expires in
     accordance with its terms, to and including such expiration date and (ii)
     in the case of a Letter of Credit that is drawn in full or is otherwise
     terminated other than on the stated expiration date of such Letter of
     Credit, to but excluding the date such Letter of Credit is drawn in full or
     is terminated (such fee to be non-refundable, to be paid in arrears on each
     Quarterly Date and on the Revolving Credit Commitment Termination Date and
     to be calculated for any day after giving effect to any payments made under
     such Letter of Credit on such day).  In addition, the Borrower shall pay to
     the Administrative Agent for account of the Issuing Lender a fronting fee
     in respect of each Letter of Credit in an amount equal to 1/4 of 1% per
     annum of the daily average undrawn face amount of such Letter of Credit for
     the period from and including the date of issuance of such Letter of Credit
     (i) in the case of a Letter of Credit that expires in accordance with its
     terms, to and including such expiration date and (ii) in the case of a
     Letter of Credit that is drawn in full or is otherwise terminated other
     than on the stated expiration date of such Letter of Credit, to but
     excluding the date such Letter of Credit is drawn in full or is terminated
     (such fee to be non-refundable, to be paid in arrears on each Quarterly
     Date and on the Revolving Credit Commitment Termination Date and to be
     calculated for any day after giving effect to any payments made under such
     Letter of Credit on such day) plus all commissions, charges, costs and
     expenses in the amounts customarily charged by the Issuing Lender from time
     to time in like circumstances with respect to the issuance of each Letter
     of Credit and drawings and other transactions relating thereto.

          (h)  Promptly following the end of each calendar quarter, the Issuing
     Lender shall deliver (through the Administrative Agent) to each Revolving
     Credit Lender and the Borrower a notice describing the aggregate amount of
     all Letters of Credit outstanding at the end of such quarter.  Upon the
     request of any Revolving Credit Lender from time to time, the Issuing
     Lender shall deliver any other information reasonably requested by such
     Lender with respect to each Letter of Credit then outstanding.

          (i)  The issuance by the Issuing Lender of each Letter of Credit
     shall, in addition to the conditions precedent set forth in Section 7
     hereof, be subject to the conditions precedent that (i) such Letter of
     Credit shall be in such form, contain such terms and support such
     transactions as shall be satisfactory to the Issuing Lender consistent with
     its then current practices and procedures with respect to letters of credit
     of the same type and (ii) the Borrower shall have executed and delivered
     such applications, agreements and other instruments relating to such Letter
     of Credit as the Issuing Lender shall have reasonably requested consistent
     with its then current practices and procedures with respect to letters of
     credit of the same type, provided that in the event of any conflict between
                              --------                                          
     any such application, agreement or other instrument and the provisions of
     this Agreement or any Security Document, the provisions of this Agreement
     and the Security Documents shall control.

 
                                                                              25

          (j)  To the extent that any Lender shall fail to pay any amount
     required to be paid pursuant to paragraph (e) or (f) of this Section 2.03
     on the due date therefor, such Lender shall pay interest to the Issuing
     Lender (through the Administrative Agent) on such amount from and including
     such due date to but excluding the date such payment is made at a rate per
     annum equal to the Federal Funds Rate, provided that if such Lender shall
                                            --------                          
     fail to make such payment to the Issuing Lender within three Business Days
     of such due date, then, retroactively to the due date, such Lender shall be
     obligated to pay interest on such amount at the Post-Default Rate.

          (k)  The issuance by the Issuing Lender of any modification or
     supplement to any Letter of Credit hereunder shall be subject to the same
     conditions applicable under this Section 2.03 to the issuance of new
     Letters of Credit, and no such modification or supplement shall be issued
     hereunder unless either (i) the respective Letter of Credit affected
     thereby would have complied with such conditions had it originally been
     issued hereunder in such modified or supplemented form or (ii) each
     Revolving Credit Lender shall have consented thereto.

The Borrower hereby indemnifies and holds harmless each Revolving Credit Lender
and the Administrative Agent from and against any and all claims and damages,
losses, liabilities, costs or expenses that such Lender or the Administrative
Agent may incur (or that may be claimed against such Lender or the
Administrative Agent by any Person whatsoever) by reason of or in connection
with the execution and delivery or transfer of or payment or refusal to pay by
the Issuing Lender under any Letter of Credit; provided that the Borrower shall
                                               --------                        
not be required to indemnify any Lender or the Administrative Agent for any
claims, damages, losses, liabilities, costs or expenses to the extent, but only
to the extent, caused by (x) the willful misconduct or gross negligence of the
Issuing Lender in determining whether a request presented under any Letter of
Credit complied with the terms of such Letter of Credit or (y) in the case of
the Issuing Lender, such Lender's failure to pay under any Letter of Credit
after the presentation to it of a request strictly complying with the terms and
conditions of such Letter of Credit unless it is prohibited from doing so by an
injunction or other order of any court.  Nothing in this Section 2.03 is
intended to limit the other obligations of the Borrower, any Lender or the
Administrative Agent under this Agreement.

          2.04  Changes of Commitments.  The Borrower shall have the right at
                ----------------------                                       
any time or from time to time (i)  so long as no Revolving Credit Loans or
Letter of Credit Liabilities are outstanding, to terminate the Revolving Credit
Commitments and (ii) to reduce the aggregate unused amount of the Revolving
Credit Commitments (for which purpose use of the Revolving Credit Commitments
shall be deemed to include the aggregate amount of Letter of Credit
Liabilities); provided that (x) the Borrower shall give notice of each such
              --------                                                     
termination or reduction as provided in Section 4.05 hereof and (y) each partial
reduction shall be in an aggregate amount at least equal to $5,000,000 (or a
larger multiple of $1,000,000).  The Commitments once terminated or reduced may
not be reinstated.

          2.05  Commitment Fee.  The Borrower shall pay to the Administrative
                --------------                                               
Agent for the account of each Lender a commitment fee on the daily average
unused amount of such Lender's Revolving Credit Commitment (for which purpose
the aggregate amount of any Letter of Credit Liabilities shall be deemed to be a
pro rata (based on the Revolving Credit Commitments) use of each Lender's

Revolving Credit Commitment) for the period from and including the
Amendment/Restatement Effective Date to but not including the earlier of the
date such Revolving Credit Commitment is terminated and the Revolving Credit
Commitment Termination Date, at a rate per annum equal to (a) 1/2 of 1%, at any
time when the Applicable Margin in respect of Eurodollar Loans that are
Revolving Credit Loans is 1.75% or higher or (b) 3/8 of 1%, at any other time.
Accrued commitment fees shall be payable on each Quarterly Date and on the
earlier of the date the relevant Commitments are terminated and the Revolving
Credit Commitment Termination Date.

 
                                                                              26

                ---------------                                             
shall be made and maintained at such Lender's Applicable Lending Office for
Loans of such Type.

          2.07  Several Obligations; Remedies Independent.  The failure of any
                -----------------------------------------                     
Lender to make any Loan to be made by it on the date specified therefor shall
not relieve any other Lender of its obligation to make its Loan on such date,
but neither any Lender nor the Administrative Agent shall be responsible for the
failure of any other Lender to make a Loan to be made by such other Lender, and
(except as otherwise provided in Section 4.06 hereof) no Lender shall have any
obligation to the Administrative Agent or any other Lender for the failure by
such Lender to make any Loan required to be made by such Lender.  The amounts
payable by the Borrower at any time hereunder and under any Notes to each Lender
shall be a separate and independent debt and each Lender shall be entitled to
protect and enforce its rights arising out of this Agreement and any Notes, and
it shall not be necessary for any other Lender or the Administrative Agent to
consent to, or be joined as an additional party in, any proceedings for such
purposes.

existence and amounts of the obligations of the Borrower therein recorded;
provided, however, that the failure of any Lender or the Administrative Agent to

maintain the Register or any such account, or any error therein, shall not in
any manner affect the obligation of the Borrower to repay (with applicable
interest) any Loan of any Class made to the Borrower by such Lender in
accordance with the terms of this Agreement.

          (e)  No Lender shall be entitled to have its Notes substituted or
exchanged for any reason, or subdivided for promissory notes of lesser
denominations, except in connection with a permitted assignment of all or any
portion of such Lender's relevant Commitment, Loans and Notes pursuant to
Section 12.06 hereof and except as provided in clause (f) below (and, if
requested by any Lender, the Borrower agrees to so exchange any Note).

          (f)  Notwithstanding the foregoing, any Lender that is not a U.S.
Person and is not a "bank" within the meaning of Section 881(c)(3)(A) of the
Code and that has made a written request to the Borrower (through the
Administrative Agent) for a promissory note and any direct or indirect assignee
of such Lender (such Lender and any such assignee, a "Qualified Foreign Lender")
                                                      ------------------------

Amendment/Restatement Effective Date, payable to such Lender or registered
assigns and otherwise duly completed.  Once issued, Registered Notes (i) shall
be deemed to and shall be "Notes" and "Tranche A Term Notes," "Tranche B Term
Notes" or "Revolving Credit Notes," as the case may be, for all purposes under
this Agreement, the Security Documents and the other Loan Documents, (ii) may
not be exchanged for Revolving Credit Notes, Tranche A Term Notes or Tranche B
Term Notes, notwithstanding anything to the contrary in this Agreement, and
(iii) shall at all times thereafter be Registered Notes, including, without
limitation, following any transfer or assignment thereof.

          (g)  Each Lender that is a "Lender" under the Existing Credit
Agreement shall return to the Borrower for cancellation any notes held by it
thereunder promptly after the Amendment/Restatement Effective Date.

          2.09  Optional Prepayments and Conversions or Continuations of Loans.
                --------------------------------------------------------------  
Subject to Section 4.04 hereof, the Borrower shall have the right to prepay
Loans, or to Convert Loans of one Type into Loans of another Type or Continue
Loans of one Type as Loans of the same Type, at any time or from time to time,
provided that:  (a) the Borrower shall give the Administrative Agent notice of
- --------                                                                      
each such prepayment, Conversion or Continuation as provided in Section 4.05
hereof (and, upon the date specified in any such notice of prepayment, the
amount to be prepaid shall become due and payable hereunder); (b) Eurodollar
Loans may be prepaid or Converted only on the last day of an Interest Period for
such Loans; (c) prepayments of the Term Loans shall be applied ratably to the
Tranche A Term Loans and the Tranche B Term Loans and, in the case of each such
Class, to the installments of the Term Loans in direct order of their scheduled
maturities; and (d) any Conversion or Continuation of Eurodollar Loans shall be
subject to the provisions of Section 2.01(d) hereof.  Notwithstanding the
foregoing, and without limiting the rights and remedies of the Lenders under
Section 10 hereof, in the event that any Event of Default shall have occurred
and be continuing, the Administrative Agent may (and at the request of the
Majority Lenders shall) suspend the right of the Borrower to Convert any Loan
into a Eurodollar Loan, or to Continue any Loan as a Eurodollar Loan, in which
event all Loans shall be Converted (on the last day(s) of the respective
Interest Periods therefor) or Continued, as the case may be, as Base Rate Loans.

 
                                                                              28

          2.10  Mandatory Prepayments.

condemnation award or other compensation in respect of any Casualty Event
affecting any Property of the Borrower or any of its Subsidiaries (or upon such
earlier date as the Borrower or such Subsidiary, as the case may be, shall have
determined not to repair or replace the Property affected by such Casualty
Event), the Borrower shall prepay the Term Loans, and the Term Loan Commitments
shall be automatically reduced in an aggregate amount, if any, equal to 100% of
the Net Available Proceeds of such Casualty Event not theretofore applied to the
repair or replacement of such Property, such prepayment and reduction to be
effected in each case in the manner and to the extent specified in paragraph (f)
of this Section 2.10.  Nothing in this paragraph (a) shall be deemed to limit
any obligation of the Borrower or any of its Subsidiaries pursuant to any of the
Security Documents to remit to a collateral or similar account (including,
without limitation, the Collateral Account) maintained by the Administrative
Agent pursuant to any of the Security Documents the proceeds of insurance,
condemnation award or other compensation received in respect of any Casualty

financial statements of the Company and its Subsidiaries in accordance with
Section 9.01(b) hereof (or, if such consolidated and consolidating financial
statements are not received by the last day on which they are required to be
delivered, not later than 30 days after the last day on which such financial
statements are required by said Section 9.01(b) to be so delivered) in respect

Available Proceeds of any Disposition (herein, the "Current Disposition"), and
                                                    -------------------       
of all prior Dispositions as to which a prepayment has not yet been made under
this Section 2.10(e), but excluding the amount of any Reinvestable Proceeds (as
defined below), shall exceed $1,000,000 then, no later than five Business Days
after the occurrence of the Current Disposition, the Borrower will deliver to
the Lenders a statement, certified by a Responsible Officer of the Borrower, in
form and detail satisfactory to the Administrative Agent, of the amount of the
Net Available Proceeds of the Current Disposition and of all such prior
Dispositions and will prepay the Term Loans in an aggregate amount equal to 100%
of the Net Available Proceeds of the Current Disposition and such prior
Dispositions, but excluding the amount of any Reinvestable Proceeds, such
prepayment to be effected in each case in the manner and to the extent specified
in paragraph (f) of this Section 2.10.  In the event that the Borrower
determines that it plans to use a portion of the Net Available Proceeds of any
Disposition (the "Reinvestable Proceeds" of such Disposition) to repair or
                  ---------------------

so to use such portion, such portion shall cease to be Reinvestable Proceeds on
such 270th day and shall be deemed to be Net Available Proceeds of a Disposition
that has occurred on such day and (ii) if after giving effect to such
determination the then aggregate amount of Reinvestable Proceeds that have not
been used to so repair or replace Properties shall be in excess of $10,000,000,
such aggregate amount shall be promptly deposited in a cash collateral account
established at Chase to be held as collateral in favor of the Administrative
Agent for the benefit of the Lenders on terms reasonably satisfactory to the
Administrative Agent and shall remain on deposit in such cash collateral account
until such aggregate amount (or, with respect to any portion thereof, such
portion) shall be used to so repair or replace Properties or as provided in
clause (i) of this Section 2.10(e).

aggregate amount of all Letter of Credit Liabilities, shall exceed the Revolving
Credit Commitments, the Borrower shall, first, pay Revolving Credit Loans and,
second, provide cover for Letter of Credit Liabilities, in an aggregate amount
equal to such excess.  In the event that the Borrower shall be required pursuant

Borrower shall effect the same by paying to the Administrative Agent immediately

date of such Loan to but excluding the date such Loan shall be paid in full, at
the following rates per annum:

          (a)  during such periods as such Loan is a Base Rate Loan, the Base
     Rate (as in effect from time to time) plus the Applicable Margin and
                                           ----                          

          (b)  during such periods as such Loan is a Eurodollar Loan, for each
     Interest Period relating thereto, the Eurodollar Rate for such Loan for
     such Interest Period plus the Applicable Margin.
                          ----                       

Notwithstanding the foregoing, the Borrower hereby promises to pay to the
Administrative Agent for account of each Lender interest at the applicable Post-
Default Rate on any principal of any Loan made by such Lender, on any
Reimbursement Obligation held by such Lender and on any other amount payable by
the Borrower hereunder or under any Notes held by such Lender to or for account
of such Lender, that shall not be paid in full when due (whether at stated
maturity, by acceleration, by mandatory prepayment or otherwise), for the period
from and including the due date thereof to but excluding the date the same is
paid in full.  Accrued interest on each Loan shall be payable (i) in the case of
a Base Rate Loan, quarterly on the Quarterly Dates, (ii) in the case of a
Eurodollar Loan, on the last day of each Interest Period therefor and, if such
Interest Period is longer than three months, at three-month intervals following
the first day of such Interest Period, and (iii) in the case of any Eurodollar
Loan, upon the payment or prepayment thereof or the Conversion of such Loan to a
Loan of another Type (but only on the principal amount so paid, prepaid or
Converted), except that interest payable at the Post-Default Rate shall be
payable from time to time on demand.  Promptly after the determination of any
interest rate provided for herein or any change therein, the Administrative
Agent shall give notice thereof to the Lenders to which such interest is payable
and to the Borrower.

                -------- 

          (a)  Except to the extent otherwise provided herein, all payments of
principal, interest, Reimbursement Obligations and other amounts to be made by
the Borrower under this Agreement and any Notes, and, except to the extent
otherwise provided therein, all payments to be made by the Obligors 

 
                                                                              32

available funds, without deduction, set-off or counterclaim, to the
Administrative Agent at the Principal Office, not later than 1:00 p.m. New York
time on the date on which such payment shall become due (each such payment made
after such time on such due date to be deemed to have been made on the next
succeeding Business Day).

          (b)  Any Lender for whose account any such payment is to be made may
(but shall not be obligated to) debit the amount of any such payment that is not
made by such time as required hereunder to any ordinary deposit account of the
Borrower with such Lender (with notice to the Borrower and the Administrative
Agent), provided that such Lender's failure to give such notice shall not affect
        --------

          (c)  The Borrower shall, at the time of making each payment under this
Agreement or any Note for account of any Lender, specify to the Administrative
Agent (which shall so notify the intended recipient(s) thereof) the Loans,
Reimbursement Obligations or other amounts payable by the Borrower hereunder to
which such payment is to be applied (and in the event that the Borrower fails to
so specify, or if such payment is equal to the then aggregate amounts due and
owing hereunder, the Administrative Agent may distribute such payment to the
Lenders for application in such ratable manner as it, subject to Section 4.02
hereof, may reasonably determine to be appropriate).

          (d)  Except to the extent otherwise provided in the last sentence of
Section 2.03(e) hereof, each payment received by the Administrative Agent under
this Agreement or any Note for account of any Lender shall be paid by the
Administrative Agent promptly to such Lender, in immediately available funds,
for account of such Lender's Applicable Lending Office for the Loan or other
obligation in respect of which such payment is made.

          (e)  If the due date of any payment under this Agreement or any Note
would otherwise fall on a day that is not a Business Day, such date shall be
extended to the next succeeding Business Day, and interest shall be payable for
any principal so extended for the period of such extension.

under Section 2.01 hereof shall be made from the relevant Lenders, each payment

respective Commitments of such Class; (b) except as otherwise provided in
Section 5.04 hereof, Eurodollar Loans of any Class having the same Interest
Period shall be allocated pro rata among the relevant Lenders according to the

amounts of their respective Revolving Credit and Term Loan Commitments (in the
case of the making of Loans) or their respective Revolving Credit and Term Loans
(in the case of Conversions and Continuations of Loans); (c) each payment or
prepayment of principal of Revolving Credit Loans or Term Loans by the Borrower
shall be made for account of the relevant Lenders pro rata in accordance with
                                                  --- ----                   
the respective unpaid principal amounts of the Loans of such Class held by them;
and (d) each payment of interest on Revolving Credit Loans and Term Loans by the
Borrower shall be made for account of the relevant Lenders pro rata in
                                                           --- ----

and actual days elapsed (including the first day but, except as otherwise
provided in Section 2.03(g) hereof, excluding the last day) occurring in the
period for which payable and interest on Base Rate Loans and Reimbursement
Obligations shall be 

 
                                                                              33

computed on the basis of a year of 365 or 366 days, as the case may be, and
actual days elapsed (including the first day but excluding the last day)
occurring in the period for which payable. Notwithstanding the foregoing, for
each day that the Base Rate is calculated by reference to the Federal Funds
Rate, interest on Base Rate Loans and Reimbursement Obligations shall be
computed on the basis of a year of 360 days and actual days elapsed.

          4.04  Minimum Amounts.  Except for mandatory prepayments made pursuant
                ---------------

larger multiple of $500,000 (borrowings, Conversions or prepayments of or into
Loans of different Types or, in the case of Eurodollar Loans, having different
Interest Periods at the same time hereunder to be deemed separate borrowings,
Conversions and prepayments for purposes of the foregoing, one for each Type or
Interest Period), and, if any Eurodollar Loans would otherwise be in a lesser
principal amount for any period, such Loans shall be Base Rate Loans during such
period.

          4.05  Certain Notices.  Notices by the Borrower to the Administrative
                ---------------

the date of the relevant termination, reduction, borrowing, Conversion,
Continuation or prepayment or the first day of such Interest Period specified
below:

Each such notice of termination or reduction shall specify the amount and the
Class of the Commitments to be terminated or reduced.  Each such notice of
borrowing, Conversion, Continuation or optional prepayment shall specify (i) the
Class of Loans to be borrowed, Converted, Continued or prepaid, (ii) the amount
(subject to Section 4.04 hereof) and Type of each Loan to be borrowed,
Converted, Continued or prepaid and (iii) the date of borrowing, Conversion,
Continuation or optional prepayment (which shall be a Business Day).  Each such
notice of the duration of an Interest Period shall specify the Loans to which

notify the Lenders of the contents of each such notice.  In the event that the
Borrower fails to select the Type of Loan, or the duration of any Interest
Period for any Eurodollar Loan, within the time period and otherwise as provided
in this Section 4.05, such Loan (if outstanding as a Eurodollar Loan) will be
automatically Converted into a Base Rate Loan on the last day of the then
current 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.

 
                                                                              34

                ------------------------------------------------             
Administrative Agent shall have been notified by a Lender or the Borrower (the
"Payor") prior to the date on which the Payor is to make payment to the
 -----                                                                 
Administrative Agent of (in the case of a Lender) the proceeds of a Loan to be
made by such Lender hereunder or (in the case of the Borrower) a payment to the
Administrative Agent for account of one or more of the Lenders hereunder (such
payment being herein called the "Required Payment"), which notice shall be
                                 ----------------                         
effective upon receipt, that the Payor does not intend to make the Required
Payment to the Administrative Agent, the Administrative Agent may assume that
the Required Payment has been made and may, in reliance upon such assumption
(but shall not be required to), make the amount thereof available to the
intended recipient(s) on such date; and, if the Payor has not in fact made the
Required Payment to the Administrative Agent, the recipient(s) of such payment
shall, on demand, repay to the Administrative Agent the amount so made available
together with interest thereon in respect of each day during the period
commencing on the date (the "Advance Date") such amount was so made available by
                             ------------                                       
the Administrative Agent until the date the Administrative Agent recovers such
amount at a rate per annum equal to the Federal Funds Rate for such day and, if
such recipient(s) shall fail promptly to make such payment, the Administrative
Agent shall be entitled to recover such amount, on demand, from the Payor,
together with interest as aforesaid, provided that if neither the recipient(s)
                                     --------                                 
nor the Payor shall return the Required Payment to the Administrative Agent
within three Business Days of the Advance Date, then, retroactively to the
Advance Date, the Payor and the recipient(s) shall each be obligated to pay
interest on the Required Payment as follows:

               (i)   if the Required Payment shall represent a payment to be
     made by the Borrower to the Lenders, the Borrower and the recipient(s)
     shall each be obligated retroactively to the Advance Date to pay interest
     in respect of the Required Payment at the Post-Default Rate (without
     duplication of the obligation of the Borrower under Section 3.02 hereof to
     pay interest on the Required Payment at the Post-Default Rate), it being
     understood that the return by the recipient(s) of the Required Payment to
     the Administrative Agent shall not limit such obligation of the Borrower
     under said Section 3.02 to pay interest at the Post-Default Rate in respect
     of the Required Payment and

               (ii)  if the Required Payment shall represent proceeds of a Loan
     to be made by the Lenders to the Borrower, the Payor and the Borrower shall
     each be obligated retroactively to the Advance Date to pay interest in
     respect of the Required Payment pursuant to whichever of the rates
     specified in Section 3.02 hereof is applicable to the Type of such Loan, it
     being understood that the return by the Borrower of the Required Payment to
     the Administrative Agent shall not limit any claim the Borrower may have
     against the Payor in respect of such Required Payment.

          4.07  Sharing of Payments, Etc.
                -------------------------

          (a)  Each Obligor agrees that, in addition to (and without limitation
of) any right of set-off, banker's lien or counterclaim a Lender may otherwise
have, each Lender shall be entitled, at its option (to the fullest extent
permitted by law), to set off and apply any deposit (general or special, time or
demand, provisional or final), or other indebtedness, held by it for the credit
or account of such Obligor at any of its offices, in Dollars or in any other
currency, against any principal of or interest on any of such Lender's Loans,
Reimbursement Obligations or any other amount payable to such Lender hereunder,
that is not paid when due (regardless of whether such deposit or other
indebtedness are then due to such Obligor), in which case it shall promptly
notify such Obligor and the Administrative Agent thereof, provided that such
                                                          --------          
Lender's failure to give such notice shall not affect the validity thereof.

          (b)  If any Lender shall obtain from any Obligor payment of any
principal of or interest on any Loan of any Class or Letter of Credit Liability
owing to it or payment of any other amount under 

 
                                                                              35

this Agreement or any other Loan Document through the exercise of any right of
set-off, banker's lien or counterclaim or similar right or otherwise (other than
from the Administrative Agent as provided herein), and, as a result of such
payment, such Lender shall have received a greater percentage of the principal
of or interest on the Loans of such Class or Letter of Credit Liabilities or
such other amounts then due hereunder or thereunder by such Obligor to such
Lender than the percentage received by any other Lender, it shall promptly
purchase from such other Lenders participations in (or, if and to the extent
specified by such Lender, direct interests in) the Loans of such Class or Letter
of Credit Liabilities or such other amounts, respectively, owing to such other
Lenders (or in interest due thereon, as the case may be) in such amounts, and
make such other adjustments from time to time as shall be equitable, to the end
that all the Lenders shall share the benefit of such excess payment (net of any
expenses that may be incurred by such Lender in obtaining or preserving such
excess payment) pro rata in accordance with the unpaid principal of and/or
                --- ----
interest on the Loans of such Class or Letter of Credit Liabilities or such
other amounts, respectively, owing to each of the Lenders. To such end all the
Lenders shall make appropriate adjustments among themselves (by the resale of
participations sold or otherwise) if such payment is rescinded or must otherwise
be restored.

          (c)  Each Obligor agrees that any Lender so purchasing such a
participation (or direct interest) may exercise all rights of set-off, banker's
lien, counterclaim or similar rights with respect to such participation as fully
as if such Lender were a direct holder of Loans or other amounts (as the case
may be) owing to such Lender in the amount of such participation.

          (d)  Nothing contained herein shall require any Lender to exercise any
such right or shall affect the right of any Lender to exercise, and retain the
benefits of exercising, any such right with respect to any other indebtedness or
obligation of any Obligor.  If, under any applicable bankruptcy, insolvency or
other similar law, any Lender receives a secured claim in lieu of a set-off to
which this Section 4.07 applies, such Lender shall, to the extent practicable,
exercise its rights in respect of such secured claim in a manner consistent with
the rights of the Lenders entitled under this Section 4.07 to share in the
benefits of any recovery on such secured claim.

          5.01  Additional Costs.
                ---------------- 

          (a)  The Borrower shall pay directly to each Lender from time to time
such amounts as such Lender may determine to be necessary to compensate such
Lender for any costs that such Lender determines are attributable to its making
or maintaining of any Eurodollar Loans or its obligation to make any Eurodollar
Loans hereunder, or any reduction in any amount receivable by such Lender
hereunder in respect of any of such Loans or such obligation (such increases in
costs and reductions in amounts receivable being herein called "Additional
                                                                ----------
Costs"), resulting from any Regulatory Change that:
- -----

               (i)   shall subject any Lender (or its Applicable Lending Office
     for any of such Loans) to any tax, duty or other charge in respect of such
     Loans or its Notes or changes the basis of taxation of any amounts payable
     to such Lender under this Agreement or its Notes in respect of any of such
     Loans (excluding changes in the rate of tax on the overall net income of
     such Lender or of such Applicable Lending Office by the jurisdiction in
     which such Lender has its principal office or such Applicable Lending
     Office); or

               (ii)  imposes or modifies any reserve, special deposit or
     similar requirements (other than the Reserve Requirement utilized in the
     determination of the Eurodollar Rate for such Loan) relating to any
     extensions of credit or other assets of, or any deposits with or other

 
                                                                              36

     liabilities of, such Lender (including, without limitation, any of such
     Loans or any deposits referred to in the definition of "Eurodollar Base
     Rate" in Section 1.01 hereof), or any commitment of such Lender (including,
     without limitation, the Commitments of such Lender hereunder); or

               (iii)    imposes any other condition affecting this Agreement or
     its Notes (or any of such extensions of credit or liabilities) or its
     Commitments.

If any Lender requests compensation from the Borrower under this Section
5.01(a), the Borrower may, by notice to such Lender (with a copy to the
Administrative Agent), suspend the obligation of such Lender thereafter to make
or Continue Eurodollar Loans, or to Convert Base Rate Loans into Eurodollar
Loans, until the Regulatory Change giving rise to such request ceases to be in
effect (in which case the provisions of Section 5.04 hereof shall be
applicable), provided that such suspension shall not affect the right of such
             --------                                                        
Lender to receive the compensation so requested.

          (b)  Without limiting the effect of the foregoing provisions of this
Section 5.01 (but without duplication), the Borrower shall pay directly to each
Lender from time to time on request such amounts as such Lender may determine to
be necessary to compensate such Lender (or, without duplication, the bank
holding company of which such Lender is a Subsidiary) for any costs that it
determines are attributable to the maintenance by such Lender (or any Applicable
Lending Office or such bank holding company), pursuant to any law or regulation
or any interpretation, directive or request (whether or not having the force of
law and whether or not failure to comply therewith would be unlawful) of any
court or governmental or monetary authority (i) following any Regulatory Change
or (ii) implementing any risk-based capital guideline or other requirement
(whether or not having the force of law and whether or not the failure to comply
therewith would be unlawful) hereafter issued by any government or governmental
or supervisory authority implementing at the national level the Basle Accord, of
capital in respect of its Commitments or Loans (such compensation to include,
without limitation, an amount equal to any reduction of the rate of return on
assets or equity of such Lender (or any Applicable Lending Office or such bank
holding company) to a level below that which such Lender (or any Applicable
Lending Office or such bank holding company) could have achieved but for such
law, regulation, interpretation, directive or request).

          (c)  Each Lender shall notify the Borrower of any event occurring
after the date hereof entitling such Lender to compensation under paragraph (a)
or (b) of this Section 5.01 as promptly as practicable, but in any event within
45 days, after such Lender obtains actual knowledge thereof; provided that (i)
                                                             --------         
if any Lender fails to give such notice within 45 days after it obtains actual
knowledge of such an event, such Lender shall, with respect to compensation
payable pursuant to this Section 5.01 in respect of any costs resulting from
such event, only be entitled to payment under this Section 5.01 for costs
incurred from and after the date 45 days prior to the date that such Lender does
give such notice and (ii) each Lender will designate a different Applicable
Lending Office for the Loans of such Lender affected by such event if such
designation will avoid the need for, or reduce the amount of, such compensation
and will not, in the sole opinion of such Lender, be disadvantageous to such
Lender, except that such Lender shall have no obligation to designate an
Applicable Lending Office located in the United States of America.  Each Lender
will furnish to the Borrower a certificate setting forth the basis and amount of
each request by such Lender for compensation under paragraph (a) or (b) of this
Section 5.01.  Determinations and allocations by any Lender for purposes of this
Section 5.01 of the effect of any Regulatory Change pursuant to paragraph (a) of
this Section 5.01, or of the effect of capital maintained pursuant to paragraph
(b) of this Section 5.01, on its costs or rate of return of maintaining Loans or
its obligation to make Loans, or on amounts receivable by it in respect of
Loans, and of the amounts required to compensate such Lender under this Section
5.01, shall be conclusive, provided that such determinations and allocations are
                           --------                                             
made on a reasonable basis.

 
                                                                              37

          5.02  Limitation on Types of Loans.  Anything herein to the contrary
                ----------------------------                                  
notwithstanding, if, on or prior to the determination of any Eurodollar Base
Rate for any Interest Period:

          (a)  the Administrative Agent determines, which determination shall be
     conclusive, that quotations of interest rates for the relevant deposits
     referred to in the definition of "Eurodollar Base Rate" in Section 1.01
     hereof are not being provided in the relevant amounts or for the relevant
     maturities for purposes of determining rates of interest for Eurodollar
     Loans as provided herein; or

          (b)  if the related Loans are Revolving Credit Loans, the Majority
     Revolving Credit Lenders or, if the related Loans are Term Loans, the
     Majority Term Lenders determine, which determination shall be conclusive,
     and notify the Administrative Agent that the relevant rates of interest
     referred to in the definition of "Eurodollar Base Rate" in Section 1.01
     hereof upon the basis of which the rate of interest for Eurodollar Loans
     for such Interest Period is to be determined are not likely adequately to
     cover the cost to such Lenders of making or maintaining Eurodollar Loans
     for such Interest Period;

then the Administrative Agent shall give the Borrower and each Lender prompt
notice thereof and, so long as such condition remains in effect, the Lenders
shall be under no obligation to make additional Eurodollar Loans, to Continue
Eurodollar Loans or to Convert Base Rate Loans into Eurodollar Loans, and the
Borrower shall, on the last day(s) of the then current Interest Period(s) for
the outstanding Eurodollar Loans, either prepay such Loans or Convert such Loans
into Base Rate Loans in accordance with Section 2.09 hereof.

          5.03  Illegality.  Notwithstanding any other provision of this
                ----------                                              
Agreement, in the event that it becomes unlawful for any Lender or its
Applicable Lending Office to honor its obligation to make or maintain Eurodollar
Loans hereunder (and, in the sole opinion of such Lender, the designation of a
different Applicable Lending Office would either not avoid such unlawfulness or
would be disadvantageous to such Lender), then such Lender shall promptly notify
the Borrower thereof (with a copy to the Administrative Agent) and such Lender's
obligation to make or Continue, or to Convert Loans of any other Type into,
Eurodollar Loans shall be suspended until such time as such Lender may again
make and maintain Eurodollar Loans (in which case the provisions of Section 5.04
hereof shall be applicable).

          5.04  Treatment of Affected Loans.  If the obligation of any Lender to
                ---------------------------                                     
make Eurodollar Loans or to Continue, or to Convert Base Rate Loans into,
Eurodollar Loans shall be suspended pursuant to Section 5.01 or 5.03 hereof,
such Lender's Eurodollar Loans shall be automatically Converted into Base Rate
Loans on the last day(s) of the then current Interest Period(s) for Eurodollar
Loans (or, in the case of a Conversion resulting from a circumstance described
in Section 5.03 hereof, on such earlier date as such Lender may specify to the
Borrower with a copy to the Administrative Agent) and, unless and until such
Lender gives notice as provided below that the circumstances specified in
Section 5.01 or 5.03 hereof that gave rise to such Conversion no longer exist:

          (a)  to the extent that such Lender's Eurodollar Loans have been so
     Converted, all payments and prepayments of principal that would otherwise
     be applied to such Lender's Eurodollar Loans shall be applied instead to
     its Base Rate Loans; and

          (b)  all Loans that would otherwise be made or Continued by such
     Lender as Eurodollar Loans shall be made or Continued instead as Base Rate
     Loans, and all Base Rate Loans of such 

 
                                                                              38

     Lender that would otherwise be Converted into Eurodollar Loans shall remain
     as Base Rate Loans.

If such Lender gives notice to the Borrower with a copy to the Administrative
Agent that the circumstances specified in Section 5.01 or 5.03 hereof that gave
rise to the Conversion of such Lender's Eurodollar Loans pursuant to this
Section 5.04 no longer exist (which such Lender agrees to do promptly upon such
circumstances ceasing to exist) at a time when Eurodollar Loans of the same
Class made by other Lenders are outstanding, such Lender's Base Rate Loans of
such Class shall be automatically Converted, on the first day(s) of the next
succeeding Interest Period(s) for such outstanding Eurodollar Loans, to the
extent necessary so that, after giving effect thereto, all Base Rate and
Eurodollar Loans of such Class are allocated among the Lenders ratably (as to
principal amounts, Types and Interest Periods) in accordance with their
respective Commitments of such Class.

          5.05  Compensation.  The Borrower shall pay to the Administrative
                ------------                                               
Agent for account of each Lender, upon the request of such Lender through the
Administrative Agent, such amount or amounts as shall be sufficient (in the
reasonable opinion of such Lender) to compensate it for any loss, cost or
expense that such Lender determines is attributable to:

          (a)  any payment, mandatory or optional prepayment or Conversion of a
     Eurodollar Loan made by such Lender for any reason (including, without
     limitation, the acceleration of the Loans pursuant to Section 10 hereof) on
     a date other than the last day of the Interest Period for such Loan; or

          (b)  any failure by the Borrower for any reason (including, without
     limitation, the failure of any of the conditions precedent specified in
     Section 7 hereof to be satisfied) to borrow a Eurodollar Loan from such
     Lender on the date for such borrowing specified in the relevant notice of
     borrowing given pursuant to Section 2.02 hereof.

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
that otherwise would have accrued on the principal amount so paid, prepaid,
Converted or not borrowed for the period from the date of such payment,
prepayment, Conversion or failure to borrow to the last day of the then current
Interest Period for such Loan (or, in the case of a failure to borrow, the
Interest Period for such Loan that would have commenced on the date specified
for such borrowing) at the applicable rate of interest for such Loan provided
for herein over (ii) the amount of interest that otherwise would have accrued on
such principal amount at a rate per annum equal to the interest component of the
amount such Lender would have bid in the London interbank market for Dollar
deposits of leading banks in amounts comparable to such principal amount and
with maturities comparable to such period (as reasonably determined by such
Lender).

          5.06  Additional Costs in Respect of Letters of Credit.  Without
                ------------------------------------------------          
limiting the obligations of the Borrower under Section 5.01 hereof (but without
duplication), if as a result of any Regulatory Change or any risk-based capital
guideline or other requirement hereafter issued by any government or
governmental or supervisory authority implementing at the national level the
Basle Accord there shall be imposed, modified or deemed applicable any tax,
reserve, special deposit, capital adequacy or similar requirement against or
with respect to or measured by reference to Letters of Credit issued or to be
issued hereunder and the result shall be to increase the cost to any Lender or
Lenders of issuing (or purchasing participations in) or maintaining its
obligation hereunder to issue (or purchase participations in) any Letter of
Credit hereunder or reduce any amount receivable by any Lender hereunder in
respect of any Letter of Credit (which increases in cost, or reductions in
amount receivable, shall be the result of such Lender's or Lenders' reasonable
allocation of the aggregate of such increases or reductions resulting from 

 
                                                                              39

such event), then, not later than five Business Days following demand by such
Lender or Lenders (through the Administrative Agent), the Borrower shall pay to
the Administrative Agent for account of such Lender or Lenders, from time to
time as specified by such Lender or Lenders (through the Administrative Agent),
such additional amounts as shall be sufficient to compensate such Lender or
Lenders (through the Administrative Agent) for such increased costs or
reductions in amount. A statement as to such increased costs or reductions in
amount incurred by any such Lender or Lenders, submitted by such Lender or
Lenders to the Borrower shall be conclusive in the absence of manifest error as
to the amount thereof.

          5.07  U.S. Taxes.
                ---------- 

          (a)  The Borrower agrees to pay to each Lender that is not a U.S.
Person such additional amounts as are necessary in order that the net payment of
any amount due to such non-U.S. Person hereunder after deduction for or
withholding in respect of any U.S. Taxes imposed with respect to such payment
(or in lieu thereof, payment of such U.S. Taxes by such non-U.S. Person), will
not be less than the amount stated herein to be then due and payable, provided
                                                                      --------
that the foregoing obligation to pay such additional amounts shall not apply:

               (i)   to any payment to any Lender hereunder (other than to any
     Qualified Foreign Lender) unless such Lender is, on the
     Amendment/Restatement Effective Date (or on the date it becomes a Lender
     hereunder as provided in Section 12.06(b) hereof) and on the date of any
     change in the Applicable Lending Office of such Lender, either entitled to
     submit a Form 1001 (relating to such Lender and entitling it to a complete
     exemption from withholding on all interest to be received by it hereunder
     in respect of the Loans) or Form 4224 (relating to all interest to be
     received by such Lender hereunder in respect of the Loans),

               (ii)  to any payment to any Qualified Foreign Lender hereunder in
     respect of its Loan, unless such Qualified Foreign Lender (or, if such
     Qualified Foreign Lender is not the beneficial owner of such Loan, the
     beneficial owner thereof) is, on the Amendment/Restatement Effective Date
     (or on the date such Qualified Foreign Lender becomes a Lender as provided
     in Section 12.06(b) hereof) and on the date of any change in the Applicable
     Lending Office of such Lender, entitled to submit a Form W-8, together with
     an annual certificate stating that such Qualified Foreign Lender (or
     beneficial owner, as the case may be) is not a "bank" within the meaning of
     Section 881(c)(3)(A) of the Code, and such Qualified Foreign Lender (or
     beneficial owner, as the case may be) shall promptly notify the Borrower if
     at any time, such Qualified Foreign Lender (or beneficial owner, as the
     case may be) determines that it is no longer in a position to provide such
     certificate to the Borrower (or any other form of certification adopted by
     the relevant taxing authorities of the United States of America for such
     purposes), or

               (iii) to any U.S. Taxes imposed solely by reason of the failure
     by such non-U.S. Person (or, if such non-U.S. Person is not the beneficial
     owner of the relevant Loan, such beneficial owner) to comply with
     applicable certification, information, documentation or other reporting
     requirements concerning the nationality, residence, identity or connections
     with the United States of America of such non-U.S. Person (or beneficial
     owner, as the case may be) if such compliance is required by statute or
     regulation of the United States of America as a precondition to relief or
     exemption from such U.S. Taxes.

For the purposes of this Section 5.07(a), (A) "Form 1001" shall mean Form 1001
                                               ---------                      
(Ownership, Exemption, or Reduced Rate Certificate) of the Department of the
Treasury of the United States of America, (B) "Form 4224" shall mean Form 4224
                                               ---------                      
(Exemption from Withholding of Tax on Income Effectively Connected with the
Conduct of a Trade or Business in the United States) of the Department 

 
                                                                              40

of the Treasury of the United States of America (or in relation to either such
Form such successor and related forms as may from time to time be adopted by the
relevant taxing authorities of the United States of America to document a claim
to which such Form relates) and (C) "Form W-8" shall mean Form W-8 (Certificate
                                     --------
of Foreign Status of the Department of Treasury of the United States of
America). Each of the Forms referred to in the foregoing clauses (A), (B) and
(C) shall include such successor and related forms as may from time to time be
adopted by the relevant taxing authorities of the United States of America to
document a claim to which such Form relates.

          (b)  Within 30 days after paying any amount to the Administrative
Agent or any Lender from which it is required by law to make any deduction or
withholding, and within 30 days after it is required by law to remit such
deduction or withholding to any relevant taxing or other authority, the Borrower
shall deliver to the Administrative Agent for delivery to such non-U.S. Person
evidence satisfactory to such Person of such deduction, withholding or payment
(as the case may be).

          (c)  Each such non-U.S. Person that is entitled to submit a Form 1001,
Form 4224 or Form W-8, together with a certificate stating that such Qualified
Foreign Lender (or beneficial owner, as the case may be) is not a "bank" within
the meaning of Section 881(c)(3)(A) of the Code and such Qualified Foreign
Lender (or beneficial owner, as the case may be) shall promptly notify the
Borrower if at any time, such Qualified Foreign Lender (or beneficial owner, as
the case may be) determines that it is no longer in a position to provide such
certificate to the Borrower (or any other form of certification adopted by the
relevant taxing authorities of the United States of America for such purposes),
shall submit the same to the Administrative Agent and to the Borrower on the
Amendment/Restatement Effective Date (or on the date it becomes a Lender
hereunder as provided in Section 12.06(b) hereof) and annually thereafter.

          5.08  Replacement of Lenders.  If any Lender requests compensation
                ----------------------                                      
pursuant to Section 5.01, 5.06 or 5.07 hereof, or any Lender's obligation to
make or Continue, or to Convert Loans of any Type into, the other Type of Loan
shall be suspended pursuant to Section 5.01 or 5.03 hereof (any such Lender
requesting such compensation, or whose obligations are so suspended, being
herein called a "Requesting Lender"), the Borrower, upon three Business Days
                 -----------------                                          
notice, may require that such Requesting Lender transfer all of its right, title
and interest under this Agreement and such Requesting Lender's Notes to any bank
or other financial institution (a "Proposed Lender") identified by the Borrower
                                   ---------------                             
that is satisfactory to the Administrative Agent and the Issuing Lender (i) if
such Proposed Lender agrees to assume all of the obligations of such Requesting
Lender hereunder, and to purchase all of such Requesting Lender's Loans
hereunder for consideration equal to the aggregate outstanding principal amount
of such Requesting Lender's Loans, together with interest thereon to the date of
such purchase, and satisfactory arrangements are made for payment to such
Requesting Lender of all other amounts payable hereunder to such Requesting
Lender on or prior to the date of such transfer (including any fees accrued
hereunder and any amounts that would be payable under Section 5.05 hereof as if
all of such Requesting Lender's Loans were being prepaid in full on such date)
and (ii) if such Requesting Lender has requested compensation pursuant to
Section 5.01, 5.06 or 5.07 hereof, such Proposed Lender's aggregate requested
compensation, if any, pursuant to said Section 5.01, 5.06 or 5.07 with respect
to such Requesting Lender's Loans is lower than that of the Requesting Lender.
Subject to the provisions of Section 12.06(b) hereof, such Proposed Lender shall
be a "Lender" for all purposes hereunder.  Without prejudice to the survival of
any other agreement of the Borrower hereunder the agreements of the Borrower
contained in Sections 5.01, 5.06, 5.07 and 12.03 hereof (without duplication of
any payments made to such Requesting Lender by the Borrower or the Proposed
Lender) shall survive for the benefit of such Requesting Lender under this
Section 5.08 with respect to the time prior to such replacement.

          Section 6.  Guarantee.
                      --------- 

          6.01  The Guarantee.  The Guarantors hereby jointly and severally
                -------------                                              
guarantee to each Lender and the Administrative Agent and their respective
successors and assigns the prompt payment in full when due (whether at stated
maturity, by acceleration or otherwise) of the principal of and interest on the
Loans made by the Lenders to, and any Notes held by each Lender of, the Borrower
and all other amounts from time to time owing to the Lenders or the
Administrative Agent by the Borrower under this Agreement and under any Notes
and by any Obligor under any of the other Loan Documents, and all obligations of
the Borrower or any of its Subsidiaries to any Lender in respect of any Interest
Rate Protection Agreement, in each case strictly in accordance with the terms
thereof (such obligations being herein collectively called the "Guaranteed
                                                                ----------
Obligations").  The Guarantors hereby further jointly and severally agree that

if the Borrower shall fail to pay in full when due (whether at stated maturity,
by acceleration or otherwise) any of the Guaranteed Obligations, the Guarantors
will promptly pay the same, without any demand or notice whatsoever, and that in
the case of any extension of time of payment or renewal of any of the Guaranteed
Obligations, the same will be promptly paid in full when due (whether at
extended maturity, by acceleration or otherwise) in accordance with the terms of
such extension or renewal.

          6.02  Obligations Unconditional.  The obligations of the Guarantors
                -------------------------                                    
under Section 6.01 hereof are absolute and unconditional, joint and several,
irrespective of the value, genuineness, validity, regularity or enforceability
of the obligations of the Borrower under this Agreement, any Notes or any other
agreement or instrument referred to herein or therein, or any substitution,
release or exchange of any other guarantee of or security for any of the
Guaranteed Obligations, and, to the fullest extent permitted by applicable law,
irrespective of any other circumstance whatsoever that might otherwise
constitute a legal or equitable discharge or defense of a surety or guarantor,
it being the intent of this Section 6.02 that the obligations of the Guarantors
hereunder shall be absolute and unconditional, joint and several, under any and
all circumstances.  Without limiting the generality of the foregoing, it is
agreed that the occurrence of any one or more of the following shall not alter
or impair the liability of the Guarantors hereunder which shall remain absolute
and unconditional as described above:

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

               (ii)     any of the acts mentioned in any of the provisions of
     this Agreement or any Notes or any other agreement or instrument referred
     to herein or therein shall be done or omitted;

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

               (iv)     any lien or security interest granted to, or in favor
     of, the Administrative Agent or any Lender or Lenders as security for any
     of the Guaranteed Obligations shall fail to be perfected.


 
                                                                              42

The Guarantors hereby expressly waive diligence, presentment, demand of payment,
protest and all notices whatsoever, and any requirement that the Administrative
Agent or any Lender exhaust any right, power or remedy or proceed against the
Borrower under this Agreement or any Notes or any other agreement or instrument
referred to herein or therein, or against any other Person under any other
guarantee of, or security for, any of the Guaranteed Obligations.  Anything
herein to the contrary notwithstanding, the maximum liability of each Subsidiary
Guarantor hereunder shall in no event exceed the amount which can be guaranteed
by such Subsidiary Guarantor under applicable federal and state laws relating to
the insolvency of debtors (after giving effect to the right of contribution
established in Section 6.08 hereof).

          6.03  Reinstatement.  The obligations of the Guarantors under this
                -------------                                               
Section 6 shall be automatically reinstated if and to the extent that for any
reason any payment by or on behalf of the Borrower in respect of the Guaranteed
Obligations is rescinded or must be otherwise restored by any holder of any of
the Guaranteed Obligations, whether as a result of any proceedings in bankruptcy
or reorganization or otherwise and the Guarantors jointly and severally agree
that they will indemnify the Administrative Agent and each Lender on demand for
all reasonable costs and expenses (including, without limitation, fees of
counsel) incurred by the Administrative Agent or such Lender in connection with
such rescission or restoration, including any such costs and expenses incurred
in defending against any claim alleging that such payment constituted a
preference, fraudulent transfer or similar payment under any bankruptcy,
insolvency or similar law.

          6.04  Subrogation.  The Guarantors hereby jointly and severally agree
                -----------                                                    
that until the payment and satisfaction in full of all Guaranteed Obligations
and the expiration and termination of the Commitments of the Lenders under this
Agreement they shall not exercise any right or remedy arising by reason of any
performance by them of their guarantee in Section 6.01 hereof, whether by
subrogation or otherwise, against the Borrower or any other guarantor of any of
the Guaranteed Obligations or any security for any of the Guaranteed
Obligations.

          6.05  Remedies.  The Guarantors jointly and severally agree that, as
                --------                                                      
between the Guarantors and the Lenders, the obligations of the Borrower under
this Agreement and any Notes may be declared to be forthwith due and payable as
provided in Section 10 hereof (and shall be deemed to have become automatically
due and payable in the circumstances provided in said Section 10) for purposes
of Section 6.01 hereof notwithstanding any stay, injunction or other prohibition
preventing such declaration (or such obligations from becoming automatically due
and payable) as against the Borrower and that, in the event of such declaration
(or such obligations being deemed to have become automatically due and payable),
such obligations (whether or not due and payable by the Borrower) shall
forthwith become due and payable by the Guarantors for purposes of said Section
6.01.

          6.06  Instrument for the Payment of Money.  Each Guarantor hereby
                -----------------------------------                        
acknowledges that the guarantee in this Section 6 constitutes an instrument for
the payment of money, and consents and agrees that any Lender or the
Administrative Agent, at its sole option, in the event of a dispute by such
Guarantor in the payment of any moneys due hereunder, shall have the right to
bring motion-action under New York CPLR Section 3213.

          6.07  Continuing Guarantee.  The guarantee in this Section 6 is a
                --------------------                                       
continuing guarantee, and shall apply to all Guaranteed Obligations whenever
arising.

          6.08  Rights of Contribution.  Each Subsidiary Guarantor hereby agrees
                ----------------------                                          
that to the extent that a Subsidiary Guarantor shall have paid more than its
proportionate share of any payment made hereunder, such Subsidiary Guarantor
shall be entitled to seek and receive contribution from and against any other
Subsidiary Guarantor hereunder which has not paid its proportionate share of
such payment.  

 
                                                                              43

Each Subsidiary Guarantor's right of contribution shall be subject to the terms
and conditions of Section 6.04 hereof. The provisions of this Section 6.08 shall
in no respect limit the obligations and liabilities of any Subsidiary Guarantor
to the Administrative Agent and the Lenders, and each Subsidiary Guarantor shall
remain liable to the Administrative Agent and the Lenders for the full amount
guaranteed by such Subsidiary Guarantor hereunder.

          6.09  General Limitation on Guarantee Obligations.  In any action or
                -------------------------------------------                   
proceeding involving any state corporate law, or any state or Federal
bankruptcy, insolvency, reorganization or other law affecting the rights of
creditors generally, if the obligations of any Subsidiary Guarantor under
Section 6.01 hereof would otherwise, taking into account the provisions of
Section 6.08 hereof, be held or determined to be void, invalid or unenforceable,
or subordinated to the claims of any other creditors, on account of the amount
of its liability under said Section 6.01, then, notwithstanding any other
provision hereof to the contrary, the amount of such liability shall, without
any further action by such Subsidiary Guarantor, any Lender, the Administrative
Agent or any other Person, be automatically limited and reduced to the highest
amount that is valid and enforceable and not subordinated to the claims of other
creditors as determined in such action or proceeding.

          6.10  Waiver.  Each Guarantor waives all rights and defenses arising
                ------                                                        
out of an election of remedies by any Lender or the Administrative Agent, even
though that election of remedies, such as a nonjudicial foreclosure with respect
to security for a Guaranteed Obligation, has destroyed such Guarantor's right of
subrogation and reimbursement against the Borrower by the operation of Section
580d of the California Code of Civil Procedure or otherwise.  The provisions of
this Section 6.10 shall apply to each of the Loan Documents as if fully set
forth therein.

                 ----------------------------                        
Subsidiaries have all right, title and interest in, or a valid and binding
license to use, the Intellectual Property (as defined below) disclosed in
Schedule V hereto, which represents all Intellectual Property individually or in
the aggregate material to the conduct of the businesses of the Borrower and its
Subsidiaries taken as a whole on the Amendment/Restatement Effective Date.
Except as disclosed in Schedule V hereto, (i) the Borrower or a Subsidiary has
the exclusive right to use the Intellectual Property disclosed in Schedule V
hereto in perpetuity and without payment of royalties, (ii) all registrations
with and applications to Governmental or Regulatory Authorities in respect of
such Intellectual Property are valid and in full force and effect and are not
subject to the payment of any taxes or maintenance fees or the taking of any
other actions by the Borrower or a Subsidiary to maintain their validity or
effectiveness, and (iii) there are no restrictions on the direct or indirect
transfer of any Contractual Obligation, or any interest therein, held by the
Borrower or any Subsidiary in respect of such Intellectual Property. Neither the
Borrower nor any Subsidiary of the Borrower is in material default (or with the
giving of notice or lapse of time or both, would be in material default) under
any license to use such Intellectual Property, such Intellectual Property is not
being materially infringed by any third party, and neither the Borrower nor any
Subsidiary of the Borrower is infringing any Intellectual Property of any third
party. For purposes of this Section 8.19, "Intellectual Property" means patents 
                                           --------------------- 
and patent rights, trademarks and trademark rights, trade names and trade name

be used for "purchasing" or "carrying" any "margin stock" within the respective
meanings of each of the quoted terms under Regulation U of the Board of
Governors of the Federal Reserve System as now and from time to time hereafter
in effect.

          8.21   Year 2000 Matters.  To the extent that the failure to do so
                 -----------------                                          
could reasonably be expected to result in a Material Adverse Effect, (a) any
reprogramming required to permit the proper functioning (but only to the extent
that such proper functioning would otherwise be impaired by the occurrence of
the year 2000) in and following the year 2000 of computer systems and other
equipment 

 
                                                                              55

containing embedded microchips, in either case owned or operated by the Parent
Guarantor or any of its Subsidiaries or used or relied upon in the conduct of
their business (including any such systems and other equipment supplied by
others or with which the computer systems of the Parent Guarantor or any of its
Subsidiaries interface and which are material to the conduct, in the ordinary
course, of business of the Parent Guarantor or any Subsidiary), and (b) the
testing of all such systems and other equipment as so reprogrammed, will be
completed by December 31, 1999. The costs to the Parent Guarantor and its
Subsidiaries that have not been incurred as of the date hereof for such
reprogramming and testing and for the other reasonably foreseeable consequences
to them of any improper functioning of other computer systems and equipment
containing embedded microchips due to the occurrence of the year 2000 could not
reasonably be expected to result in a Default or Event of Default or to have a
Material Adverse Effect. Except for any reprogramming referred to above, the
computer systems of the Parent Guarantor and its Subsidiaries are and, with
ordinary course upgrading and maintenance, will continue for the term of this
Agreement to be, reasonably sufficient for the conduct of their business as
currently conducted.

     clear of all other Liens, or, (ii) except for expiration in accordance with
     its terms, any of the Security Documents shall for whatever reason be
     terminated or cease to be in full force and effect, or the enforceability
     thereof shall be contested by any Obligor, or (iii) Section 6 shall cease,
     for any reason, to be in full force and effect or any Guarantor shall so

THEREUPON:  (1) in the case of an Event of Default other than one referred to in
clause (f) or (g) of this Section 10 with respect to any Obligor, the
Administrative Agent may (and upon the request of the Majority Lenders shall),
by notice to the Borrower, terminate the Commitments and/or declare the
principal amount then outstanding of, and the accrued interest on, the Loans,
the Reimbursement Obligations and all other amounts payable by the Obligors
hereunder and under any Notes (including, without limitation, any amounts
payable under Section 5.05 or 5.06 hereof) to be forthwith due and payable,
whereupon such amounts shall be immediately due and payable without presentment,
demand, protest or other formalities of any kind, all of which are hereby
expressly waived by each Obligor; and (2) in the case of the occurrence of an
Event of Default referred to in clause (f) or (g) of this Section 10 with
respect to any Obligor, the Commitments shall automatically be terminated and
the principal amount then outstanding of, and the accrued interest on, the
Loans, the Reimbursement Obligations and all other amounts payable by the
Obligors hereunder and under any Notes (including, without limitation, any
amounts payable under Section 5.05 or 5.06 hereof) shall automatically become
immediately due and payable without presentment, demand, protest or other
formalities of any kind, all of which are hereby expressly waived by each
Obligor.

 
                                                                              71

          In addition, upon the occurrence and during the continuance of any
Event of Default (if the Administrative Agent has declared the principal amount
then outstanding of, and accrued interest on, the Revolving Credit Loans and all
other amounts payable by the Borrower hereunder and under any Notes to be due
and payable), the Borrower agrees that it shall, if requested by the
Administrative Agent or the Majority Revolving Credit Lenders through the
Administrative Agent (and, in the case of any Event of Default referred to in
clause (f) or (g) of this Section 10 with respect to the Borrower or the Parent
Guarantor, forthwith, without any demand or the taking of any other action by
the Administrative Agent or such Lenders) provide cover for the Letter of Credit
Liabilities by paying to the Administrative Agent immediately available funds in
an amount equal to the then aggregate undrawn face amount of all Letters of
Credit, which funds shall be held by the Administrative Agent in the Collateral
Account as collateral security in the first instance for the Letter of Credit
Liabilities and be subject to withdrawal only as therein provided.

The Administrative Agent may employ agents and attorneys-in-fact and shall not
be responsible for the negligence or misconduct of any such agents or attorneys-
in-fact selected by it in good faith.  The Administrative Agent may deem and
treat the payee (or Registered Holder, as the case may be) of a Note as the
holder thereof for all purposes hereof unless and until a notice of the
assignment or transfer thereof shall have been filed with the Administrative
Agent.

 
                                                                              72

          11.02  Reliance by Administrative Agent.  The Administrative Agent
                 --------------------------------                           
shall be entitled to rely upon any certification, notice or other communication
(including, without limitation, any thereof by telephone, telecopy, telegram or
cable) reasonably believed by it to be genuine and correct and to have been
signed or sent by or on behalf of the proper Person or Persons, and upon advice
and statements of legal counsel, independent accountants and other experts
selected by the Administrative Agent.  As to any matters not expressly provided
for by this Agreement or any other Loan Document, the Administrative Agent shall
in all cases be fully protected in acting, or in refraining from acting,
hereunder or thereunder in accordance with instructions given by the Majority
Lenders or, if provided herein, in accordance with the instructions given by the
Majority Revolving Credit Lenders, the Majority Term Lenders or all of the
Lenders as is required in such circumstance, and such instructions of such
Lenders and any action taken or failure to act pursuant thereto shall be binding
on all of the Lenders.

          11.03  Defaults.  The Administrative Agent shall not be deemed to have
                 --------                                                       
knowledge or notice of the occurrence of a Default unless the Administrative
Agent has received notice from a Lender or the Borrower specifying such Default
and stating that such notice is a "Notice of Default".  In the event that the
Administrative Agent receives such a notice of the occurrence of a Default, the
Administrative Agent shall give prompt notice thereof to the Lenders.  The
Administrative Agent shall (subject to Section 11.07 hereof) take such action
with respect to such Default as shall be directed by the Majority Lenders or, if
provided herein, the Majority Revolving Credit Lenders or the Majority Term
Lenders, provided that, unless and until the Administrative Agent shall have
         --------                                                           
received such directions, the Administrative Agent may (but shall not be
obligated to) take such action, or refrain from taking such action, with respect
to such Default as it shall deem advisable in the best interest of the Lenders
except to the extent that this Agreement expressly requires that such action be
taken, or not be taken, only with the consent or upon the authorization of the
Majority Lenders, the Majority Revolving Credit Lenders, the Majority Term
Lenders or all of the Lenders.

          11.04  Rights as a Lender.  With respect to its Commitments and the
                 ------------------                                          
Loans made by it, Chase (and any successor acting as Administrative Agent) in
its capacity as a Lender hereunder shall have the same rights and powers
hereunder as any other Lender and may exercise the same as though it were not
acting as the Administrative Agent, and the term "Lender" or "Lenders" shall,
unless the context otherwise indicates, include the Administrative Agent in its
individual capacity.  Chase (and any successor acting as Administrative Agent)
and its affiliates may (without having to account therefor to any Lender) accept
deposits from, lend money to, make investments in and generally engage in any
kind of banking, trust or other business with the Obligors (and any of their
Subsidiaries or Affiliates) as if it were not acting as the Administrative
Agent, and Chase (and any such successor) and its affiliates may accept fees and
other consideration from the Obligors for services in connection with this
Agreement or otherwise without having to account for the same to the Lenders.

          11.05  Indemnification.  The Lenders agree to indemnify the
                 ---------------                                     
Administrative Agent (to the extent not reimbursed under Section 12.03 hereof,
but without limiting the obligations of the Borrower under said Section 12.03)
ratably in accordance with the aggregate principal amount of the Loans and
Reimbursement Obligations held by the Lenders (or, if no Loans or Reimbursement
Obligations are at the time outstanding, ratably in accordance with their
respective Commitments), for any and all liabilities, obligations, losses,
damages, penalties, actions, judgments, suits, costs, expenses or disbursements
of any kind and nature whatsoever that may be imposed on, incurred by or
asserted against the Administrative Agent (including by any Lender) arising out
of or by reason of any investigation in or in any way relating to or arising out
of this Agreement or any other Loan Document or any other documents contemplated
by or referred to herein or therein or the transactions contemplated hereby or
thereby (including, without limitation, the costs and expenses that the Borrower
is obligated to pay under Section 12.03 hereof, but excluding, unless a Default
has occurred and is continuing, normal administrative costs and expenses
incident to the performance of its agency duties hereunder) or the 

 
                                                                              73

enforcement of any of the terms hereof or thereof or of any such other
documents, provided that no Lender shall be liable for any of the foregoing to 
           --------
the extent they arise from the gross negligence or willful misconduct of the
party to be indemnified.

          11.06  Non-Reliance on Administrative Agent and Other Lenders.  Each
                 ------------------------------------------------------       
Lender agrees that it has, independently and without reliance on the
Administrative Agent or any other Lender, and based on such documents and
information as it has deemed appropriate, made its own credit analysis of the
Parent Guarantor and its Subsidiaries and decision to enter into this Agreement
and that it will, independently and without reliance upon the Administrative
Agent or any other Lender, and based on such documents and information as it
shall deem appropriate at the time, continue to make its own analysis and
decisions in taking or not taking action under this Agreement or under any other
Loan Document.  The Administrative Agent shall not be required to keep itself
informed as to the performance or observance by any Obligor of this Agreement or
any of the other Loan Documents or any other document referred to or provided
for herein or therein or to inspect the Properties or books of the Parent
Guarantor or any of its Subsidiaries.  Except for notices, reports and other
documents and information expressly required to be furnished to the Lenders by
the Administrative Agent hereunder or under the Security Documents, the
Administrative Agent shall not have any duty or responsibility to provide any
Lender with any credit or other information concerning the affairs, financial
condition or business of the Parent Guarantor or any of its Subsidiaries (or any
of their affiliates) that may come into the possession of the Administrative
Agent or any of its affiliates.

          11.07  Failure to Act.  Except for action expressly required of the
                 --------------                                              
Administrative Agent hereunder and under the other Loan Documents, the
Administrative Agent shall in all cases be fully justified in failing or
refusing to act hereunder and thereunder unless it shall receive further
assurances to its satisfaction from the Lenders of their indemnification
obligations under Section 11.05 hereof against any and all liability and expense
that may be incurred by it by reason of taking or continuing to take any such
action.

          11.08  Resignation or Removal of Administrative Agent.  Subject to the
                 ----------------------------------------------                 
appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by giving notice thereof
to the Lenders and the Borrower and the Parent Guarantor, and the Administrative
Agent may be removed at any time with or without cause by the Majority Lenders.
Upon any such resignation or removal, the Majority Lenders shall have the right
to appoint a successor Administrative Agent.  If no successor Administrative
Agent shall have been so appointed by the Majority Lenders and shall have
accepted such appointment within 30 days after the retiring Administrative
Agent's giving of notice of resignation or the Majority Lenders' removal of the
retiring Administrative Agent, then the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor Administrative Agent, that shall be a
bank that has an office in New York, New York with a combined capital and
surplus of at least $500,000,000.  Upon the acceptance of any appointment as
Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder.  After any retiring Administrative Agent's
resignation or removal hereunder as Administrative Agent, the provisions of this
Section 11 shall continue in effect for its benefit in respect of any actions
taken or omitted to be taken by it while it was acting as the Administrative
Agent.

          11.09  Consents under Other Loan Documents.  Except as otherwise
                 -----------------------------------                      
provided in Section 12.04 hereof with respect to this Agreement, the
Administrative Agent may, with the prior consent of the Majority Lenders (but
not otherwise), consent to any modification, supplement or waiver under any of
the Loan Documents, provided that, without the prior consent of each Lender, the
                    --------                                                    
Administrative Agent

 
                                                                              74

shall not (except as provided herein, in the Security Documents or in the
Assumption Agreements) release any collateral or otherwise terminate any Lien
under any Security Document providing for collateral security, agree to
additional obligations being secured by such collateral security (unless the
Lien for such additional obligations shall be junior to the Lien in favor of the
other obligations secured by such Security Document, in which event the
Administrative Agent may consent to such junior Lien provided that it obtains
the consent of the Majority Lenders thereto), alter the relative priorities of
the obligations entitled to the benefits of the Liens created under the Security
Documents, except that no such consent shall be required, and the Administrative
Agent is hereby authorized, to release any Lien covering Property that is the
subject of either a disposition of Property permitted hereunder or a disposition
to which the Majority Lenders have consented.

          Section 12.  Miscellaneous.
                       ------------- 

          12.01  Waiver.  No failure on the part of the Administrative Agent or
                 ------                                                        
any Lender to exercise and no delay in exercising, and no course of dealing with
respect to, any right, power or privilege under this Agreement or any Note shall
operate as a waiver thereof, nor shall any single or partial exercise of any
right, power or privilege under this Agreement or any Note preclude any other or
further exercise thereof or the exercise of any other right, power or privilege.
The remedies provided herein are cumulative and not exclusive of any remedies
provided by law.

          Each Obligor irrevocably waives, to the fullest extent permitted by
applicable law, any claim that any action or proceeding commenced by the
Administrative Agent or any Lender relating in any way to this Agreement should
be dismissed or stayed by reason, or pending the resolution, of any action or
proceeding commenced by any Obligor relating in any way to this Agreement
whether or not commenced earlier.  To the fullest extent permitted by applicable
law, the Obligors shall take all measures necessary for any such action or
proceeding commenced by the Administrative Agent or any Lender to proceed to
judgment prior to the entry of judgment in any such action or proceeding
commenced by any Obligor.

          12.02  Notices.  All notices, requests and other communications
                 -------

Agreement) shall be given or made in writing (including, without limitation, by
telecopy) delivered to the intended recipient addressed as follows in the case

     Tranche A Lenders" without the consent of all the Tranche A Lenders;

          (e)  reduce the percentage in the definition of the term "Majority
     Tranche B Lenders" without the consent of all the Tranche B Lenders;

          (f)  reduce the percentage in the definition of the term "Majority
     Revolving Credit Lenders" without the consent of all the Revolving Credit
     Lenders;

          (g)  amend, modify or waive any provision of Section 11 hereof or any
     other rights or duties of the Administrative Agent hereunder  without the
     written consent of the then Administrative Agent;

          (h)  amend, modify or waive any provision of Section 6 hereof without
     the written consent of each Guarantor;

          (i)  amend, modify or waive any provision relating to rights or duties

          (j)  unless by an instrument signed by all of the affected Lenders,
     convert any Loan into equity of any Obligor.

Any such waiver and any such amendment, supplement or modification shall apply
equally to each of the Lenders and shall be binding upon the Borrower, the
Lenders, the Administrative Agent and all future holders of the Loans.  In the
case of any waiver, the Borrower, the Lenders and the Administrative Agent 

 
                                                                              78

shall be restored to their former positions and rights hereunder and under the
other Loan Documents, and any Default or Event of Default waived shall be deemed
to be cured and not continuing; no such waiver shall extend to any subsequent or
other Default or Event of Default or impair any right consequent thereon.

          Anything in this Agreement to the contrary notwithstanding, no waiver
or modification of any provision of this Agreement that has the effect (either
immediately or at some later time) of enabling the Borrower to satisfy a
condition precedent to the making of a Revolving Credit Loan shall be effective
against the Revolving Credit Lenders for the purposes of the Revolving Credit
Commitments unless the Majority Revolving Credit Lenders shall have concurred
with such waiver or modification.

          12.05  Successors and Assigns.  This Agreement shall be binding upon
                 ----------------------                                       
and inure to the benefit of the parties hereto and their respective successors
and permitted assigns.

          12.06  Assignments and Participations.
                 ------------------------------ 

          (a)  No Obligor may assign any of its rights or obligations hereunder
or under any Notes without the prior consent of all of the Lenders and the
Administrative Agent.

          (b)  Any Lender may, in the ordinary course of its business and in
accordance with applicable law, at any time and from time to time assign to any
Lender or any Affiliate thereof or, with the prior written consent of the
Borrower and the Administrative Agent (which in each case shall not be
unreasonably withheld), to an additional bank or financial institution or
investment funds which invest in credit facilities (an "Assignee") all or any
                                                        --------             
part of its rights and obligations under this Agreement and any Notes,
including, without limitation, its Revolving Credit Commitment, Term Loan
Commitments, Loans, and, if such Lender is a Revolving Credit Lender, its Letter
of Credit Interest (pursuant to an Assignment and Acceptance, substantially in
the form of Exhibit E, executed by such Assignee, such assigning Lender (and, in
the case of an Assignee that is not then a Lender or an Affiliate thereof, by
the Borrower and the Administrative Agent) and delivered to the Administrative
Agent for its acceptance and recording in the Register;  provided that (unless
                                                         --------             
the Borrower and the Administrative Agent otherwise consent in writing)

               (i)   except to the extent the Borrower and the Administrative
     Agent shall otherwise consent, any such partial assignment (other than to
     another Lender) shall be in an amount at least equal to $5,000,000;

               (ii)  each such assignment by a Lender of its Revolving Credit
     Loans, Revolving Credit Note, Revolving Credit Commitment or Letter of
     Credit Interest shall be made in such manner so that the same portion of
     its Revolving Credit Loans, Revolving Credit Note, Revolving Credit
     Commitment and Letter of Credit Interest is assigned to the respective
     assignee;

               (iii) each such assignment by a Lender of its Tranche A Term
     Loans or Tranche A Term Loan Commitment shall be made in such manner so
     that the same portion of its Tranche A Term Loans and Tranche A Term Loan
     Commitment is assigned to the respective assignee; and

               (iv)  each such assignment by a Lender of its Tranche B Term
     Loans or Tranche B Term Loan Commitment shall be made in such manner so
     that the same portion of its Tranche B Term Loans and Tranche B Term Loan
     Commitment is assigned to the respective assignee.

 
                                                                              79

Upon such execution, delivery, acceptance and recording, from and after the
effective date determined pursuant to such Assignment and Acceptance, (x) the
Assignee thereunder shall be a party hereto and, to the extent provided in such
Assignment and Acceptance, have the rights and obligations of a Lender hereunder
with a Revolving Credit Commitment and, if applicable, Letter of Credit Interest
(or a portion thereof) and the Term Loan Commitment and the Term Loans, as set
forth therein, and (y) the assigning Lender thereunder shall be released from
its obligations under this Agreement to the extent that such obligations shall
have been expressly assumed by the Assignee pursuant to such Assignment and
Acceptance (and, in the case of an Assignment and Acceptance covering all or the
remaining portion of an assigning Lender's rights and obligations under this
Agreement, such assigning Lender shall cease to be a party hereto but shall
nevertheless continue to be entitled to the benefits of Sections 5.01, 5.05,
5.06, 5.07 and 12.03).  Notwithstanding the foregoing, no Assignee, which as of
the date of any assignment to it pursuant to this Section 12.06(b) would be
entitled to receive any greater payment under Section 5.01 or 5.07 than the
assigning Lender would have been entitled to receive as of such date under such
Sections with respect to the rights assigned, shall be entitled to receive such
payments unless the Borrower has expressly consented in writing to waive the
benefit of this provision at the time of the assignment.

          (c)  A Lender may sell or agree to sell to one or more other Persons
(each a "Participant") a participation in all or any part of any Loans or Letter
         -----------                                                            
of Credit Interest held by it, or in its Commitments, provided that such
                                                      --------          
Participant shall not have any rights or obligations under this Agreement or any
Note or any other Loan Document (the Participant's rights against such Lender in
respect of such participation to be those set forth in the agreements executed
by such Lender in favor of the Participant).  All amounts payable by the
Borrower to any Lender under Section 5 hereof in respect of Loans, Letter of
Credit Interest held by it, and its Commitments, shall be determined as if such
Lender had not sold or agreed to sell any participations in such Loans, Letter
of Credit Interest and Commitments, and as if such Lender were funding each of
such Loan, Letter of Credit Interest and Commitments in the same way that it is
funding the portion of such Loan, Letter of Credit Interest and Commitments in
which no participations have been sold.  In no event shall a Lender that sells a
participation agree with the Participant to take or refrain from taking any
action hereunder or under any other Loan Document except that such Lender may
agree with the Participant that it will not, without the consent of the
Participant, agree to (i) increase or extend the term of such Lender's related
Commitment or extend the amount or date of any scheduled reduction of such
Commitment pursuant to Section 2.04 hereof, (ii) extend the date fixed for the
payment of principal of or interest on the related Loan or Loans, Reimbursement
Obligations or any portion of any fee hereunder payable to the Participant,
(iii) reduce the amount of any such payment of principal, (iv) reduce the rate
at which interest is payable thereon, or any fee hereunder payable to the
Participant, to a level below the rate at which the Participant is entitled to
receive such interest or fee or (v) consent to any modification, supplement or
waiver hereof or of any of the other Loan Documents to the extent that the same,
under Section 11.09 or 12.04 hereof, requires the consent of each Lender.

          (d)  In addition to the assignments and participations permitted under
the foregoing provisions of this Section 12.06, any Lender may (without notice
to the Borrower, the Administrative Agent or any other Lender and without
payment of any fee) (i) assign and pledge all or any portion of its Loans and
its Notes to any Federal Reserve Bank as collateral security pursuant to
Regulation A and any Operating Circular issued by such Federal Reserve Bank and
(ii) assign all or any portion of its rights under this Agreement and its Loans
and its Notes to an affiliate.  No such assignment shall release the assigning
Lender from its obligations hereunder.

          (e)  A Lender may furnish any information concerning the Borrower or
any of its Subsidiaries in the possession of such Lender from time to time to
assignees and participants (including prospective assignees and participants),
subject, however, to the provisions of Section 12.12(b) hereof.

 
                                                                              80

          (f)  Anything in this Section 12.06 to the contrary notwithstanding,
no Lender may assign or participate any interest in any Loan or Reimbursement
Obligation held by it hereunder to the Borrower or any of its Affiliates or
Subsidiaries without the prior consent of each Lender.

          (g)  The Administrative Agent, on behalf of the Borrower, shall
maintain at its Principal Office a copy of each Assignment and Acceptance
delivered to it and a register (the "Register") for the recordation of the names
                                     --------                                   
and addresses of the Lenders and the Revolving Credit Commitment and Term Loan
Commitments of, and the principal amount of the Loans owing to, and any Notes
evidencing such Loans owned by, each Lender from time to time.  Notwithstanding
anything in this Agreement to the contrary, the Borrower, the Administrative
Agent and the Lenders shall treat each Person whose name is recorded in the
Register as the owner of any Loan, any Notes and the Revolving Credit
Commitments and Term Loan Commitments recorded therein for all purposes of this
Agreement.  The Register shall be available for inspection by the Borrower or
any Lender at any reasonable time and from time to time upon reasonable prior
notice.

          (h)  Notwithstanding anything in this Agreement to the contrary, no
assignment under Section 12.06(b) of any rights or obligations under or in
respect of the Loans or any Notes evidencing such Loans shall be effective
unless and until the Administrative Agent shall have recorded the assignment
pursuant to Section 12.06(g).  Upon its receipt of an Assignment and Acceptance
executed by an assigning Lender and an Assignee (and, in the case of an Assignee
that is not then a Lender or an Affiliate thereof, by the Borrower and the
Administrative Agent), together with payment to the Administrative Agent of a
registration and processing fee of $3,500, the Administrative Agent shall (i)
promptly accept such Assignment and Acceptance and (ii) on the effective date
determined pursuant thereto record the information contained therein in the
Register and give prompt notice of such acceptance and recordation to the
Lenders and the Borrower.  On or prior to such effective date, the assigning
Lender shall surrender any outstanding Notes held by it all or a portion of
which are being assigned, and the Borrower, at its own expense, shall, upon the
request to the Administrative Agent by the assigning Lender or the Assignee, as
applicable, execute and deliver to the Administrative Agent (in exchange for the
outstanding Notes of the assigning Lender, if any) a new Revolving Credit Note,
Tranche A Term Note and/or Tranche B Term Note, as the case may be (such new
Note to be a new Registered Note in the case of an assignment by or to a
Qualified Foreign Lender), to the order of such Assignee in an amount equal to
(i) in the case of a Revolving Credit Note, the amount of such Assignee's
Revolving Credit Commitment, (ii) in the case of a Tranche A Term Note, the
amount of such Assignee's Tranche A Term Loans and (iii) in the case of a
Tranche B Term Note, the amount of such Assignee's Tranche B Term Loan, and, if
the assigning Lender has retained a Revolving Credit Commitment or Term Loan
hereunder, a new Revolving Credit Note, Tranche A Term Note and/or Tranche B
Term Note, as the case may be, to the order of the assigning Lender in an amount
equal to (i) in the case of a Revolving Credit Note, the lesser of (A) the
amount of such Lender's Revolving Credit Commitment and (B) the aggregate
principal amount of all Revolving Credit Loans made by such Lender, (ii) in the
case of a Tranche A Term Note, the amount of such Lender's Tranche A Term Loans
and (iii) in the case of a Tranche B Term Note, the amount of such Lender's
Tranche B Term Loan, in each case with respect to the relevant Loan or Revolving
Credit Commitment after giving effect to such Assignment and Acceptance.  Any
such new Notes shall be dated the Closing Date, and shall otherwise be in the
form of any Note replaced thereby.  Any Notes surrendered by the assigning
Lender shall be returned by the Administrative Agent to the Borrower marked
"cancelled".

          12.07  Survival.  The obligations of the Borrower under Sections 5.01,
                 --------                                                       
5.05, 5.06, 5.07 and 12.03 hereof, the obligations of each Guarantor under
Section 6.03 hereof, and the obligations of the Lenders under Section 11.05
hereof, shall survive the repayment of the Loans and Reimbursement Obligations
and the termination of the Commitments and, in the case of any Lender that may
assign any 

 
                                                                              81

interest in its Commitments, Loans or letter of Credit Interest hereunder, shall
survive the making of such assignment, notwithstanding that such assigning
Lender may cease to be a "Lender" hereunder. In addition, each representation
and warranty made, or deemed to be made by a notice of any extension of credit
(whether by means of a Loan or a Letter of Credit) herein or pursuant hereto
shall survive the making of such representation and warranty, and no Lender
shall be deemed to have waived, by reason of making any extension of credit
hereunder (whether by means of a Loan or a Letter of Credit) any Default that
may arise by reason of such representation or warranty proving to have been
false or misleading, notwithstanding that such Lender or the Administrative
Agent may have had notice or knowledge or reason to believe that such
representation or warranty was false or misleading at the time such extension of
credit was made.

                 -------------------------------------------------              
the Borrower and the Parent Guarantor acknowledges that from time to time
financial advisory, investment banking and other services may be offered or
provided to the Borrower, the Parent Guarantor or one or more of their
Subsidiaries (in connection with this Agreement or otherwise) by any Lender or
by one or more Subsidiaries or affiliates of such Lender and each of the
Borrower and the Parent Guarantor hereby authorizes each Lender to share any
information delivered to such Lender by the Borrower, the Parent Guarantor and
their Subsidiaries pursuant to this Agreement, or in connection with the
decision of such Lender to enter into this Agreement, to any such Subsidiary or
affiliate, it being understood that any such Subsidiary or affiliate receiving
such information shall be bound by the provisions of paragraph (b) below as if
it were a Lender hereunder.  Such authorization shall survive the repayment of
the Loans and Reimbursement Obligations and the termination of the Commitments.

          (b)    Each Lender and the Administrative Agent agrees (on behalf of
itself and each of its affiliates, directors, officers, employees and
representatives) to use reasonable precautions to keep confidential, in

the Borrower pursuant to this Agreement that is identified by such Person as
being confidential at the time the same is delivered to the Lenders or the
Administrative Agent, provided that nothing herein shall limit the disclosure of

any such information (i) after such information shall have become public (other
than through a violation of this Section 12.12), (ii) to the extent required by
statute, rule, regulation or judicial process, (iii) to counsel for any of the
Lenders or the Administrative Agent, (iv) to bank examiners (or any other
regulatory authority having jurisdiction over any Lender or the Administrative
Agent), or to auditors or accountants, (v) to the Administrative Agent or any
other Lender (or to Chase Securities, Inc.), (vi) in connection with any

of such Lender as provided in paragraph (a) above, (viii) to any direct or

specifically prohibited by applicable law or court order, each Lender and the
Administrative Agent shall, prior to disclosure thereof, notify the Borrower of
any request for disclosure of any such non-public information (A) by any
governmental agency or representative thereof (other than any such request in
connection with an examination of the financial condition of such Lender by such
governmental agency) or (B) pursuant to legal process and (y) in no event shall
any Lender or the Administrative Agent be obligated or required to return any
materials furnished by the Parent Guarantor or the Borrower.  The obligations of
each Lender under this Section 12.12 shall supersede and replace the obligations
of such Lender under the confidentiality letter in respect of this financing
signed and delivered by such Lender to the Borrower prior to the
Amendment/Restatement Effective Date; in addition, the obligations of any
assignee that has executed a Confidentiality Agreement in the form of Exhibit D
hereto shall be superseded by this Section 12.12 upon the date upon which such
assignee becomes a Lender hereunder pursuant to Section 12.06(b) hereof.
