interest in 100% of its interest in its First-Tier Domestic Subsidiaries, and
66-2/3% of its interest in its First-Tier Foreign Subsidiaries will continue as
security for the payment and performance of the Obligations of the Borrower
hereunder and under the Term Loan Facility.

     E.   The Borrower agrees to cause each of its Subsidiaries that is a
Guarantor under the Subsidiary Guaranty to confirm and agree that such
Subsidiary Guaranty will continue as a guaranty of the Obligations hereunder and
under the Term Loan Facility.

Pledgor under any Subsidiary Pledge Agreement to confirm and agree that such

                   ----------------                                          
time during the Swing Line Commitment Period in an aggregate principal amount at
any one time outstanding not to exceed the Swing Line Commitment, provided that
immediately after making each Swing Line Loan, (i) the Swing Line Lender's
Credit Exposure would not exceed the Swing Line Lender's Revolving Credit
Commitment, (ii) the aggregate unpaid balance of the Swing Line Loans would not
exceed the Swing Line Commitment, and (iii) the Aggregate Credit Exposure of all
Lenders would not exceed the Aggregate Revolving Credit Commitments.  During the
Swing Line Commitment Period, the Borrower may borrow, prepay in whole or in
part and reborrow under the Swing Line Commitment, all in accordance with the
terms and conditions of this Agreement.  Each Swing Line Loan shall mature and
be due and payable on the last day of the Interest Period therefor.

          (b) The Swing Line Lender shall not be obligated to make any Swing
Line Loan at a time when any Lender shall be in default of its obligations under
this Agreement unless the Swing Line Lender has entered into arrangements
satisfactory to it and the Borrower to eliminate the Swing Line Lender's risk
with respect to such defaulting Lender's participation in such Swing Line Loan.
The Swing Line Lender will not make a Swing Line Loan if the Administrative
Agent, or any Lender by notice to the Swing Line Lender and the Borrower no
later than one Business Day prior to the Borrowing Date with respect to such
Swing Line Loan, shall have determined that the conditions set forth in Section
6 have not been satisfied and such conditions remain unsatisfied as of the
requested time of the making such Loan. Each Swing Line Loan shall be due and
payable on the day being the earliest of the last day of the Interest Period
applicable thereto, the date on which the Swing Line Commitment shall have been
voluntarily terminated by the Borrower in accordance with Section 2.6, and the
date on which the Swing Line Loans shall become due and payable pursuant to the
provisions hereof, whether by acceleration or otherwise.

                                      -30-

 
          (c) On any Business Day on which a Swing Line Loan shall be due and
payable and shall remain unpaid, the Swing Line Lender may, in its sole
discretion, give notice to the Lenders and the Borrower that such outstanding
Swing Line Loan shall be funded with a borrowing of Revolving Credit Loans
(provided that such notice shall be deemed to have been automatically given upon
the occurrence of a Default or an Event of Default under Sections 9.1(h) or
(i)), in which case a borrowing of Revolving Credit Loans made as ABR Advances
(each such borrowing, a "Mandatory Borrowing"), shall be made by all Lenders pro
                         -------------------                                    
rata based on each such Lender's Commitment Percentage on the Business Day
immediately succeeding the giving of such notice. The proceeds of each Mandatory
Borrowing shall be remitted directly to the Swing Line Lender to repay such
outstanding Swing Line Loan. Each Lender irrevocably agrees to make a Revolving
Credit Loan pursuant to each Mandatory Borrowing in the amount and in the manner
specified in the preceding sentence and on the date specified in writing by the
Swing Line Lender notwithstanding: (i) the amount of such Mandatory Borrowing
may not comply with the minimum amount for Loans otherwise required hereunder,
(ii) whether any condition specified in Section 6 is then unsatisfied, (iii)
whether a Default or an Event of Default then exists, (iv) the Borrowing Date of
such Mandatory Borrowing, (v) the aggregate principal amount of all Loans then
outstanding, (vi) the Aggregate Credit Exposure at such time and (vii) the
amount of the Commitments at such time.

     2.4. Swing Line Note
          ---------------

          The Swing Line Loans made by the Swing Line Lender shall be evidenced
by a promissory note of the Borrower, substantially in the form of Exhibit B-2,
with appropriate insertions therein as to date and principal amount (as indorsed
or modified from time to time, including all replacements thereof and
substitutions therefor, the "Swing Line Note"), payable to the order of the
                             ---------------                               
Swing Line Lender and representing the obligation of the Borrower to pay the
lesser of (i) the amount of the Swing Line Commitment and (ii) the aggregate
unpaid principal balance of all Swing Line Loans with interest thereon as set
forth in Section 2.10. The Swing Line Note shall be stated to mature on the
Swing Line Termination Date, and bear interest for the period from and including
the date thereof on the unpaid principal balance thereof from time to time
outstanding at the applicable interest rate or rates per annum determined as
provided in Section 2.10.  Interest on the Swing Line Note shall be payable as
specified in Section 2.10.

     2.5. Procedure for Borrowing
          -----------------------

          (a) Revolving Credit Loans. The Borrower may borrow under the
              ----------------------                                   
Aggregate Revolving Credit Commitments on any Business Day during the Revolving
Credit Commitment Period, provided, however, that the Borrower shall notify the
Administrative Agent (by telecopy or other written notice) no later than: 2:00
P.M. three Business Days prior to the requested Borrowing Date in the case of
Eurodollar Advances, 2:00 P.M. four Business Days prior to the requested
Borrowing Date in the case of Alternate Currency Advances, and 2:00 P.M. one
Business Day prior to the requested Borrowing Date, in the case of ABR Advances,
specifying (i) the aggregate principal amount to be borrowed under the Aggregate
Revolving Credit Commitments, (ii) the requested Borrowing Date, (iii)  whether
such borrowing is to consist of one or more Eurodollar Advances, Alternate
Currency Advances, ABR Advances, or a combination thereof and (iv) if the
borrowing is to consist of one or more Eurodollar Advances or Alternate Currency
Advance, 

                                      -31-

 
the length of the Interest Period for each such Eurodollar Advance or Alternate
Currency Advance, provided, however, that no Interest Period selected in respect
of any Revolving Credit Loan shall end after the Maturity Date. If the Borrower
fails to give timely notice in connection with a request for a Eurodollar
Advance, the Borrower shall be deemed to have elected that such Advance shall be
made as an ABR Advance. Each such notice shall be irrevocable and confirmed
immediately by delivery to the Administrative Agent of a Borrowing Request. Each
ABR Advance shall be in an aggregate principal amount equal to $1,000,000 or
such amount plus a whole multiple of $250,000 in excess thereof (or, if less,
the unused amount of the Aggregate Revolving Credit Commitments), each
Eurodollar Advance shall be in an aggregate principal amount equal to $5,000,000
or such amount plus a whole multiple of $500,000 in excess thereof, and each
Alternate Currency Advance shall be in the aggregate principal amount having a
Dollar Equivalent equal approximately to $5,000,000 or such amount plus a whole
multiple having a Dollar Equivalent of approximately $500,000 in excess thereof.

          (b) Swing Line Loans. The Borrower may borrow under the Swing Line
              ----------------                                              
Commitment on any Business Day during the Swing Line Commitment Period,
provided, however, that the Borrower shall notify the Administrative Agent and
the Swing Line Lender (by telephone or fax) no later than 3:00 P.M. on the
requested Borrowing Date, specifying (i) the amount to be borrowed under the
Swing Line Commitment, (ii) the length of the Interest Period for each such
Swing Line Loan, provided, however, that no Interest Period selected in respect
of any Swing Line Loan shall end after the Swing Line Termination Date, and
(iii) the requested Borrowing Date.  Each such notice shall be irrevocable and
confirmed immediately by delivery to the Administrative Agent of a Borrowing
Request.  Each borrowing of Swing Line Loans shall be in an aggregate principal
amount equal to $250,000 or such amount plus an integral multiple of $100,000 in
excess thereof or, if less, the unused amount of the Swing Line Commitment. The
Swing Line Lender will then, subject to its determination that the terms and
conditions of this Agreement have been satisfied, make the requested amount
available promptly on that same day, to the Administrative Agent who, thereupon,
will promptly make such amount available to the Borrower at the office of the
Administrative Agent specified in Section 11.2 by crediting the account of the
Borrower on the books of such office of the Administrative Agent.

          (c) Upon receipt of each notice of borrowing of Revolving Credit Loans
from the Borrower, the Administrative Agent shall promptly notify each Lender
thereof.  Subject to its receipt of the notice referred to in the preceding
sentence, each Lender will make the amount of its Commitment Percentage of each
Revolving Credit Loan available to the Administrative Agent for the account of
the Borrower at the applicable Agent Payment Office not later than 12:00 Noon
(local time in the city in which the applicable Agent Payment Office is located)
on the relevant Borrowing Date requested by the Borrower, in the applicable
Currency and in funds immediately available to the Administrative Agent at such
Agent Payment Office.  The amounts so made available to the Administrative Agent
on such Borrowing Date will then, subject to the satisfaction of the terms and
conditions of this Agreement, as determined by the Administrative Agent, be made
available on such date to the Borrower by the Administrative Agent at the
applicable Agent Payment Office in the applicable Currency.

          (d) Unless the Administrative Agent shall have received prior notice
from a Lender (by telephone or otherwise, such notice to be promptly confirmed
by fax or other writing) that such Lender will not make available to the
Administrative Agent such 

                                      -32-

 
Lender's Commitment Percentage of the Revolving Credit Loans requested by the
Borrower, the Administrative Agent may assume that such Lender has made such
share available to the Administrative Agent on the Borrowing Date in accordance
with this Section, provided that such Lender received notice of the proposed
borrowing from the Administrative Agent, and the Administrative Agent may, in
reliance upon such assumption, make available to the Borrower on the Borrowing
Date a corresponding amount. If and to the extent such Lender shall not have so
made its Commitment Percentage of such Revolving Credit Loans available to the
Administrative Agent, such Lender and the Borrower severally agree to pay to the
Administrative Agent forthwith on demand such corresponding amount (to the
extent not previously paid by the other), together with interest thereon for
each day from the date such amount is made available to the Borrower to the date
such amount is paid to the Administrative Agent, at a rate per annum equal to,
(i) in the case of the Borrower, the applicable interest rate set forth in
Section 2.10, and, (ii) in the case of such Lender, the Federal Funds Rate (or,
in the case of each Alternate Currency Revolving Credit Loan, a rate determined
by the Administrative Agent to be reflective of the all-in cost of funds to the
Administrative Agent in funding such Alternate Currency Revolving Credit Loan)
in effect on each such day (as determined by the Administrative Agent) plus any
processing fee per the interbank compensation rules as then in effect. Such
payment by the Borrower, however, shall be without prejudice to its rights
against such Lender. If such Lender shall pay to the Administrative Agent such
corresponding amount, such amount so paid shall constitute such Lender's
Revolving Credit Loan as part of the Revolving Credit Loans for purposes of this
Agreement, which Revolving Credit Loan shall be deemed to have been made by such
Lender on the Borrowing Date applicable to such Revolving Credit Loans.

          (e) If a Lender makes a new Revolving Credit Loan on a Borrowing Date
on which the Borrower is to repay a Revolving Credit Loan from such Lender in
the same Currency as such new Revolving Credit Loan, such Lender shall apply the
proceeds of such new Revolving Credit Loan to make such repayment, and only the
excess of the proceeds of such new Revolving Credit Loan over the Revolving
Credit Loan being repaid need be made available to the Administrative Agent.

          (f) Notices of borrowing given by telecopy shall be deemed given when
received by telecopy and shall be promptly confirmed in writing within five
Business Days.  The Administrative Agent and the Lenders may rely on a
telecopied notice of borrowing whether or not such notice is confirmed by the
delivery of a Borrowing Request.

     2.6. Termination or Reduction of Aggregate Revolving Credit Commitments and
          ----------------------------------------------------------------------
Swing Line Commitment.
- --------------------- 

          (a) Voluntary Reductions. (i) The Borrower shall have the right, upon
              --------------------                                             
at least three Business Days' prior written notice to the Administrative Agent,
at any time, to terminate the Aggregate Revolving Credit Commitments or from
time to time to reduce permanently the Aggregate Revolving Credit Commitments to
an amount not less than the Aggregate Credit Exposure, provided, however, that
any such reduction shall be in the amount of $10,000,000 or such amount plus a
whole multiple of $1,000,000 in excess thereof.

                                      -33-

 
          (ii) The Borrower shall have the right, upon at least one Business
Day's prior written notice to the Administrative Agent and the Swing Line
Lender, at any time, to reduce permanently the Swing Line Commitment in whole at
any time, or in part from time to time, to an amount not less than the aggregate
principal balance of the Swing Line Loans then outstanding (after giving effect
to any contemporaneous prepayment thereof), provided, however, that each partial
reduction of the Swing Line Commitment shall be in an amount equal to $1,000,000
or such amount plus a whole multiple of $1,000,000 in excess thereof.

          (b) Mandatory Periodic Reductions.  The Aggregate Revolving Credit
              -----------------------------                                 
Commitments shall be reduced on each of the following dates by the amount set
forth next to such date:


                             Aggregate Revolving
                             Credit Commitments
            Dates            Reduction
            -----            -------------------
                           
 
     September 30, 2001      $ 89,100,000
     September 30, 2002      $148,400,000
     September 30, 2003      $237,500,000

          (c) Mandatory Reductions Relating to a Change of Control.  Upon the
              ----------------------------------------------------           
occurrence of a Change of Control, the  Aggregate Revolving Credit Commitments
and the Swing Line Commitment shall be reduced  to $0.

          (d) Mandatory Reductions Relating to Issuances of Public Debt,
              ----------------------------------------------------------
Subordinated Indebtedness and Sales of Property.  On each date that a prepayment
- -----------------------------------------------                                 
is made or required pursuant to Section 2.7(d) or (f), the Aggregate Revolving
Credit Commitments shall be automatically and permanently reduced in an amount
equal to the amount of the required prepayment (assuming, solely for purposes of
this Section 2.6(d), that the then outstanding amount of Revolving Credit Loans
equals or exceeds the amount of such prepayment).  On each date that a
prepayment is made or required pursuant to Section 2.7(e) in connection with the
issuance by the Borrower of Subordinated Indebtedness (assuming, solely for
purposes of this Section 2.6(d), that the then outstanding amount of Revolving
Credit Loans equals or exceeds the amount of such prepayment), the Aggregate
Revolving Credit Commitments shall be automatically and permanently reduced in
an amount equal to (x) the aggregate proceeds (net of sales and other
commissions and legal and other related expenses incurred in connection with
such issuance) received by the Borrower in connection with such issuance of
Subordinated Indebtedness to the extent that such net proceeds, when added to
the aggregate proceeds (net of sales and other commissions and legal and other
related expenses incurred in connection with such issuance) received by the
Borrower in connection with the issuance of all other Subordinated Indebtedness
after the Effective Date, exceed $200,000,000 less (y) the aggregate amount of
prior reductions of the Aggregate Revolving Credit Commitments made pursuant to
this sentence.

          (e) Mandatory Reductions Relating to Reductions or Prepayments under
              ----------------------------------------------------------------
the Term Loan Facility.  On each date that a reduction of the term loan
- ----------------------                                                 
commitments under the Term Loan Facility or the prepayment of term loans
outstanding under the Term Loan Facility is made (other than with respect to
Section 2.4(d) of the Term Loan Facility 

                                      -34-

 
or with respect to a refinancing of the Term Loan Facility permitted by Section
8.9), the Aggregate Revolving Credit Commitments shall be automatically and
permanently reduced in an amount equal to the amount of such reduction or
prepayment made under the Term Loan Facility multiplied by the Revolver
Multiple.

          (f) In General. Reductions of the Aggregate Revolving Credit
              ----------                                              
Commitments shall be applied to reduce the Revolving Credit Commitments of the
Lenders pro rata.  Simultaneously with each reduction of the Aggregate Revolving
Credit Commitments under this Section, the Borrower shall pay the Commitment Fee
accrued on the amount by which the Aggregate Revolving Credit Commitments have
been reduced and prepay the Revolving Credit Loans and the Swing Line Loans as
required by Section 2.7(b).

     2.7. Prepayments of the Revolving Credit Loans
          -----------------------------------------

          (a) Voluntary Prepayments. The Borrower may, at its option, prepay the
              ---------------------                                             
Revolving Credit Loans without premium or penalty, in full at any time or in
part from time to time, by notifying the Administrative Agent in writing at
least one Business Day prior to the proposed prepayment date, in the case of
Revolving Credit Loans consisting of ABR Advances, and at least three Business
Days prior to the proposed prepayment date, in the case of Revolving Credit
Loans consisting of Eurodollar Advances or Alternate Currency Advances,
specifying the Revolving Credit Loans to be prepaid, whether such Revolving
Credit Loans consist of ABR Advances, Eurodollar Advances, Alternate Currency
Advances, or a combination thereof, the amount to be prepaid (stated in the
applicable Currency) and the date of prepayment.  Such notice shall be
irrevocable and the amount specified in such notice shall be due and payable on
the date specified, together with accrued interest to the date of such payment
on the amount prepaid.  Upon receipt of such notice, the Administrative Agent
shall promptly notify each Lender thereof.  Each partial prepayment made
pursuant to this subsection shall be (A) with respect to ABR Advances and
Eurodollar Advances, in an aggregate principal amount of $1,000,000 or such
amount plus a whole multiple of $250,000 in excess thereof (or, if less, the
outstanding principal balance of the Revolving Credit Loans), and (B) in the
case of Alternate Currency Advances, in an aggregate principal amount in the
applicable Currency having an Alternate Currency Equivalent of approximately
$1,000,000 or such amount plus an amount in the applicable Currency having an
Alternate Currency Equivalent of a whole multiple of approximately $250,000 in
excess thereof (or, if less, the outstanding principal balance of the Revolving
Credit Loans).  After giving effect to any partial prepayment (A) with respect
to Eurodollar Advances that were made (whether as the result of a borrowing or a
conversion) on the same date and that had the same Interest Period, the
outstanding principal amount of such Eurodollar Advances shall equal (subject to
Section 2.9) $5,000,000 or such amount plus a whole multiple of $500,000 in
excess thereof, and (B) with respect to Alternate Currency Advances denominated
in the same Currency that were made (whether as the result of a borrowing or a
conversion) on the same date and that had the same Interest Period, the
outstanding principal amount of such Alternate Currency Advances shall equal
(subject to Section 2.9) an amount in such Currency having a Dollar Equivalent
of approximately $5,000,000 or such amount plus an amount in such Currency
having a Dollar Equivalent of a whole multiple of approximately $500,000 in
excess thereof.

                                      -35-

 
          (b) Mandatory Prepayments Relating to Reductions of the Aggregate
              -------------------------------------------------------------
Revolving Credit Commitments and the Swing Line Commitment.  Simultaneously with
- ----------------------------------------------------------                      
each reduction of the Aggregate Revolving Credit Commitments or the Swing Line
Commitment under Section 2.6, the Borrower shall prepay the Revolving Credit
Loans or the Swing Line Loans, as the case may be, by the amount, if any, by
which (i) in the case of a reduction of the Aggregate Revolving Credit
Commitments, the Aggregate Credit Exposure exceeds the amount of the Aggregate
Revolving Credit Commitments after giving effect to such reduction and (ii) in
the case of a reduction of the Swing Line Commitment, the outstanding principal
balance of the Swing Line Loans exceeds the amount of the Swing Line Commitment
after giving effect to such reduction.  If, after giving effect to the
prepayment of all outstanding Revolving Credit Loans and Swing Line Loans, the
Letter of Credit Exposure exceeds the Aggregate Revolving Credit Commitments
(after giving effect to such reduction), the Borrower shall deposit an amount
equal to such excess in a cash collateral account (the "Cash Collateral
                                                        ---------------
Account") with and under the exclusive control of the Administrative Agent.

          (c) Mandatory Prepayments Relating to a Change of Control.  Upon the
              -----------------------------------------------------           
occurrence of a Change of Control, the Borrower shall (i) prepay in full the
outstanding principal balance of the Revolving Credit Loans and the Swing Line
Loans, together with accrued and unpaid interest thereon, (ii) pay in full all
fees and other amounts payable under the Loan Documents and (iii) deposit an
amount equal to the Letter of Credit Exposure in the Cash Collateral Account.

          (d) Mandatory Prepayments Relating to Issuances of Public Debt.  Upon
              ----------------------------------------------------------       
the date of any issuance of Public Debt by the Borrower, the Borrower shall
prepay the Revolving Credit Loans in an amount equal to the aggregate proceeds
of such issuance of Public Debt (net of sales and other commissions and legal
and other related expenses incurred in connection with such issuance).

          (e) Mandatory Prepayments Relating to Issuances of Subordinated
              -----------------------------------------------------------
Indebtedness.  Upon the date of any issuance of Subordinated Indebtedness by the
- ------------                                                                    
Borrower, the Borrower shall prepay the Revolving Credit Loans in an amount
equal to the aggregate proceeds (net of sales and other commissions and legal
and other related expenses incurred in connection with such issuance) received
by the Borrower in connection with such issuance of Subordinated Indebtedness.

          (f) Mandatory Prepayments Relating to Sales of Property.  (i) With
              ---------------------------------------------------           
respect to each Asset Sale, the Borrower shall prepay the Revolving Credit Loans
in an amount equal to the sum of (A) the Revolver Prepayment Fraction multiplied
by the Total Prepayment Amount, plus (B) 50% of the amount equal to the
difference between (1) the Term Prepayment Fraction multiplied by the Total
Prepayment Amount, and (2) the amount the Term Loans are actually prepaid under
the Term Loan Facility in connection with such sale.  Such prepayment shall be
made on the earlier of (x) the last day of the Reinvestment Period with respect
to such sale, or (y) the occurrence of an Event of Default.

          (ii) On each date on which any mandatory prepayment of term loans is
required under Section 2.4(d)(i) of the Term Loan Facility, the Borrower shall
prepay the Revolving Credit Loans in an amount equal to the Total Prepayment
Amount (as such term is defined in the Term Loan Facility) multiplied by the
Revolver Prepayment 

                                      -36-

 
Fraction; provided, however, that if any prepayment is required to be made under
Section 2.7(f)(i) on any date on which a prepayment is required to be made under
this Section 2.7(f)(ii), for purposes of this Section 2.7(f)(ii), the "Total
Prepayment Amount" (as such term is defined in the Term Loan Facility) on such
date shall be reduced (to an amount not less than zero) by the "Total Prepayment
Amount" (as such term is defined herein) on such date.

          (g) Mandatory Prepayments Relating to Aggregate Credit Exposure.  If,
              -----------------------------------------------------------      
on the last day of any fiscal quarter, the Aggregate Credit Exposure shall
exceed the Aggregate Revolving Credit Commitments, the Borrower shall prepay the
Loans in an aggregate principal amount such that immediately after giving effect
thereto the Aggregate Credit Exposure shall not exceed the Aggregate Revolving
Credit Commitments.  If, after giving effect to the prepayment of all
outstanding Loans, the Letter of Credit Exposure exceeds the Aggregate Revolving
Credit Commitments, the Borrower shall deposit an amount equal to such excess in
the Cash Collateral Account.

          (h) Mandatory Prepayments Relating to Aggregate Alternate Currency
              --------------------------------------------------------------
Exposure.  If, on the last day of any fiscal quarter, the Aggregate Alternate
- --------                                                                     
Currency Exposure shall exceed $125,000,000, the Borrower shall prepay Alternate
Currency Revolving Credit Loans in an aggregate principal amount such that
immediately after giving effect thereto the Aggregate Alternate Currency
Exposure shall not exceed $125,000,000.  If, after giving effect to the
prepayment of all outstanding Alternate Currency Revolving Credit Loans, the
Letter of Credit Exposure for all Lenders attributable to Alternate Currency
Letters of Credit exceeds $100,000,000, the Borrower shall deposit an amount
equal to such excess in the Cash Collateral Account.

          (i) In General. Each prepayment of Revolving Credit Loans denominated
              ----------                                                       
in Dollars shall first be applied to ABR Advances.  If any prepayment is made in
respect of any Eurodollar Advance, Alternate Currency Advance or Swing Line
Loan, in whole or in part, prior to the last day of the applicable Interest
Period, the Borrower agrees to indemnify the Lenders in accordance with Section
2.15.

     2.8. Participation in Swing Line Loans
          ---------------------------------

          (a) Upon each receipt by a Lender of notice of an Event of Default
from the Administrative Agent pursuant to Section 10.5, such Lender shall
purchase unconditionally, irrevocably, and severally (and not jointly) from the
Swing Line Lender a participation in the outstanding Swing Line Loans (including
accrued interest thereon) in an amount equal to the product of its Commitment
Percentage and the outstanding amount of the Swing Line Loans (the "Swing Line
                                                                    ----------
Participation Amount").  Each Lender shall also be liable for an amount equal to
- --------------------                                                            
the product of its Commitment Percentage and any amounts paid by the Borrower
pursuant to Section 2.8(c) that are subsequently rescinded or avoided, or must
otherwise be restored or returned.  Such liabilities shall be unconditional and
without regard to the occurrence of any Default or Event of Default or the
compliance by the Borrower with any of its obligations under the Loan Documents.

          (b) In furtherance of subsection (a), upon each receipt by a Lender of
notice of an Event of Default from the Administrative Agent pursuant to Section
10.5, such Lender shall promptly make available to the Administrative Agent for
the account of the Swing Line Lender its Swing Line Participation Amount at the
office of the 

                                      -37-

 
Administrative Agent specified in Section 11.2, in Dollars and in immediately
available funds. The Administrative Agent shall deliver the payments made by
each Lender pursuant to the immediately preceding sentence to the Swing Line
Lender promptly upon receipt thereof in like funds as received. Each Lender
shall indemnify and hold harmless the Administrative Agent and the Swing Line
Lender from and against any and all losses, liabilities (including liabilities
for penalties), actions, suits, judgments, demands, costs and expenses resulting
from any failure on the part of such Lender to pay, or from any delay in paying,
the Administrative Agent any amount such Lender is required to pay in accordance
with this Section 2.8(b) upon receipt of notice of Event of Default from the
Administrative Agent pursuant to Section 10.5 (except in respect of losses,
liabilities or other obligations suffered by the Administrative Agent or the
Swing Line Lender, as the case may be, resulting from the gross negligence or
willful misconduct of the Administrative Agent or the Swing Line Lender, as the
case may be), and such Lender shall be required to pay interest to the
Administrative Agent for the account of the Swing Line Lender from the date such
amount was due until paid in full, on the unpaid portion thereof, at a rate of
interest per annum equal to (i) from the date such amount was due until the
third day therefrom, the Federal Funds Rate, and (ii) thereafter, the Federal
Funds Rate plus 1%, payable upon demand by the Swing Line Lender. The
           ----
Administrative Agent shall distribute such interest payments to the Swing Line
Lender upon receipt thereof in like funds as received.

          (c) Whenever the Administrative Agent is reimbursed by the Borrower,
for the account of the Swing Line Lender, for any payment in connection with
Swing Line Loans and such payment relates to an amount previously paid by a
Lender pursuant to this Section, the Administrative Agent will promptly pay over
such payment to such Lender.

     2.9. Conversions and Continuations
          -----------------------------

          (a) The Borrower may elect from time to time to convert Eurodollar
Advances to ABR Advances by giving the Administrative Agent at least one
Business Day's prior irrevocable notice of such election (confirmed by the
delivery of a Notice of Conversion/Continuation), specifying the amount to be so
converted.  In addition, the Borrower may elect from time to time to (i) convert
ABR Advances to Eurodollar Advances, (ii) continue Eurodollar Advances by
selecting a new Interest Period therefor, and (iii) continue Alternate Currency
Advances in the same applicable Currency by selecting a new Interest Period
therefor, in each case by giving the Administrative Agent irrevocable notice no
later than 2:00 P.M. at least three Business Days prior to such election
(confirmed by the delivery of a Notice of Conversion/Continuation), in the case
of a conversion to, or continuation of, Eurodollar Advances or Alternate
Currency Advances, as the case may be, specifying the amount to be so converted
or continued and the initial Interest Period relating thereto, provided that any
such conversion of ABR Advances to Eurodollar Advances shall only be made on a
Business Day and any such continuation of Eurodollar Advances or Alternate
Currency Advances shall only be made on the last day of the Interest Period
applicable to the Eurodollar Advances or the Alternate Currency Advances that
are to be continued as such new Eurodollar Advances or Alternate Currency
Advances, as the case may be.  The Administrative Agent shall promptly provide
the Lenders with a copy of each such Notice of Conversion/Continuation.
Advances may be converted or continued pursuant to this Section in whole or in
part, provided that (A) conversions of ABR Advances to Eurodollar Advances, or
continuations of Eurodollar Advances, shall be in an aggregate principal amount
of $5,000,000 or such amount plus a 

                                      -38-

 
whole multiple of $500,000 in excess thereof, and (B) continuations of Alternate
Currency Advances denominated in the same Currency shall be in an aggregate
principal amount having a Dollar Equivalent of approximately $5,000,000 or such
amount plus an amount in such Currency having a Dollar Equivalent of a whole
multiple of approximately $500,000 in excess thereof.

          (b) Notwithstanding anything in this Section to the contrary, no ABR
Advance may be converted to a Eurodollar Advance and no Eurodollar Advance may
be continued if the Borrower or the Administrative Agent has knowledge that a
Default or Event of Default has occurred and is continuing either (i) at the
time the Borrower shall notify the Administrative Agent of its election to
convert or continue or (ii) on the requested Conversion/Continuation Date.  In
such event, (A) each ABR Advance shall be automatically continued as an ABR
Advance, (B) each Eurodollar Advance shall be automatically converted to an ABR
Advance on the last day of the Interest Period applicable to such Eurodollar
Advance and (C) each Alternate Currency Advance shall, on the last day of the
Interest Period applicable thereto, be automatically continued as a new
Alternate Currency Advance in the same applicable Currency with a one month
Interest Period.

          (c) No Interest Period selected in respect of conversion or
continuation of any Eurodollar Advance or Alternate Currency Advance shall end
after the Maturity Date. Notwithstanding anything herein to the contrary, the
Borrower shall select Interest Periods such that, on each date that a mandatory
principal payment is required to be made pursuant to Section 2.7(b) in
connection with a mandatory scheduled Commitment reduction required to be made
pursuant to Section 2.6(b), the outstanding principal balance of all ABR
Advances, when added to the aggregate principal amount of each Eurodollar
Advance and Alternate Currency Advance, the applicable Interest Period of which
shall end on such date, shall equal or exceed the aggregate principal amount of
the Revolving Credit Loans required to be paid on such date pursuant to Section
2.7(b).

          (d) Each conversion or continuation shall be effected by each Lender
by applying the proceeds of its new ABR Advance, Eurodollar Advance or Alternate
Currency Advance, as the case may be, to its Advances (or portion thereof) being
converted (it being understood that such conversion shall not constitute a
borrowing for purposes of Sections 4 or 6).

          (e) Notwithstanding anything to the contrary contained in any Loan
Document, if the Borrower shall fail, for any reason, to convert or continue a
Eurodollar Advance or an Alternate Currency Advance, as the case may be, under
this Section 2.9 in connection with the expiration of an Interest Period with
respect to any existing Eurodollar Advance or Alternate Currency Advance, as the
case may be, then (i) such Eurodollar Advance shall be converted to an ABR
Advance, and (ii) such Alternate Currency Advance shall be continued as a new
Alternate Currency Advance in the same applicable Currency with a one month
Interest Period, in each case until such time, if any, as the Borrower shall
elect a new Eurodollar Advance or Alternate Currency Advance, as the case may
be, pursuant to this Section 2.9.

          (f) Notices in respect of a conversion or continuation given by
telecopy shall be deemed given when received by telecopy and shall be promptly
confirmed in writing within five Business Days.  The Administrative Agent and
the Lenders may rely 

                                      -39-

 
on a telecopied notice of conversion or continuation whether such notice is
confirmed by the delivery of a Notice of Conversion/Continuation.

     2.10.  Interest Rate and Payment Dates
            -------------------------------

          (a) Prior to Maturity. Except as otherwise provided in Section
              -----------------                                         
2.10(b), prior to maturity the Loans shall bear interest on the outstanding
principal balance thereof at the applicable interest rate or rates per annum set
forth below:
 
 
          ADVANCES/LOANS                 RATE
          --------------                 ----
                               
          Each ABR Advance       Alternate Base Rate.

          Each Eurodollar        Eurodollar Rate applicable
          Advance                to such Eurodollar Advance for the 
                                 applicable Interest Period plus
                                 the Applicable Margin.

          Each Alternate         Alternate Currency Euro Rate
          Currency Advance       applicable to such Alternate Currency 
                                 Advance for the applicable Interest Period 
                                 plus the Applicable Margin

          Each Swing Line Loan   Either the Negotiated Rate applicable to such
                                 Swing Line Loan for the applicable Interest
                                 Period or, if the Borrower and the Swing Line
                                 Lender shall not have agreed to a Negotiated
                                 Rate with respect to such Swing Line Loan, the
                                 Alternate Base Rate for such Swing Line Loan
                                 for the applicable Interest Period.
 

          (b) Event of Default. After the occurrence and during the continuance
              ----------------                                                 
of an Event of Default under Section 9.1(a), (b) (with respect to interest, the
Commitment Fee, the LC Fronting Fee or the Letter of Credit Fee), (h) or (i),
the outstanding principal balance of the Loans shall bear interest at a rate per
annum equal to 2% plus the rate that would otherwise be applicable under Section
2.10(a) until, in the case of Eurodollar Advances and Swing Line Loans, the end
of the applicable Interest Period therefor, and, thereafter, at the Alternate
Base Rate plus 2%, payable in the case of interest on any overdue principal, on
demand.  Any overdue interest or other amount payable under the Loan Documents
shall bear interest at a rate per annum equal to the Alternate Base Rate plus 2%
and shall be payable on demand.  If all or any portion of any reimbursement
obligation in respect of a Letter of Credit shall not be paid when due (whether
at the stated maturity thereof, by acceleration or otherwise), such overdue
amount shall bear interest at a rate per annum equal to the Alternate Base Rate
plus 2%, from the date of such nonpayment until paid in full (whether before or
after the entry of a judgment thereon) and shall be payable on demand.

          (c) In General. Interest on (i) ABR Advances and Swing Line Loans, in
              ----------                                                       
each case to the extent based on the BNY Rate, and Alternate Currency Advances
in 

                                      -40-

 
Sterling Pounds shall be calculated on the basis of a 365 or 366-day year (as
the case may be),  (ii) ABR Advances and Swing Line Loans, in each case to the
extent based on the Federal Funds Rate, Eurodollar Advances and Alternate
Currency Advances in French Francs, German Marks and Japanese Yen shall be
calculated on the basis of a 360-day year, in each case for the actual number of
days elapsed, including the first day but excluding the last, and (iii) Swing
Line Loans to the extent based on a Negotiated Rate shall be calculated on the
basis of a 360-day year for the actual number of days elapsed, including the
first day but excluding the last. Except as otherwise provided in Section
2.10(b), interest shall be payable in arrears on each Interest Payment Date and
upon each payment (including prepayment) or conversion of the Loans.  Any change
in the interest rate on the Loans resulting from a change in the Alternate Base
Rate or reserve requirements or charges described in clause (b) of the
definition of "Alternate Currency Euro Rate" or "Eurodollar Rate" shall become
effective as of the opening of business on the day on which such change shall
become effective.  The Administrative Agent shall, as soon as practicable,
notify the Borrower and the Lenders of the effective date and the amount of each
such change in the BNY Rate, but any failure to so notify shall not in any
manner affect the obligation of the Borrower to pay interest on the Loans in the
amounts and on the dates required.  Each determination of the Alternate Base
Rate or a Eurodollar Rate or an Alternate Currency Euro Rate by the
Administrative Agent pursuant to this Agreement shall be conclusive and binding
on the Borrower absent manifest error.  At no time shall the interest rate
payable on the Loans, together with the Commitment Fee, the Letter of Credit
Fee, the LC Fronting Fee, and all other amounts payable under the Loan
Documents, to the extent the same are construed to constitute interest, exceed
the Highest Lawful Rate.  If in respect of any period during the term of this
Agreement, any amount paid hereunder, to the extent the same shall (but for the
provisions of this Section) constitute or be deemed to constitute interest,
would exceed the maximum amount of interest permitted by the Highest Lawful Rate
during such period (such excess amount being hereinafter referred to as an
                                                                          
"Unqualified Amount"), then (i) such Unqualified Amount shall be applied or
- -------------------                                                        
shall be deemed to have been applied as a prepayment of the Loans, and (ii) if
in any subsequent period during the term of this Agreement, all amounts payable
hereunder in respect of such period that constitute or shall be deemed to
constitute interest shall be less than the maximum amount of interest permitted
by the Highest Lawful Rate during such period, then the Borrower shall pay to
the Lender in respect of such period an amount (each a "Compensatory Interest
                                                        ---------------------
Payment") equal to the lesser of (x) a sum that, when added to all such amounts,
- -------                                                                         
would equal the maximum amount of interest permitted by the Highest Lawful Rate
during such period, and (y) an amount equal to the Unqualified Amount less all
other Compensatory Interest Payments made in respect thereof.  The Borrower
acknowledges that to the extent interest payable on ABR Advances or Swing Line
Loans is based on the BNY Rate, such Rate is only one of the bases for computing
interest on loans made by the Lenders, and by basing interest payable on ABR
Advances or Swing Line Loans on the BNY Rate, the Lenders have not committed to
charge, and the Borrower has not in any way bargained for, interest based on a
lower or the lowest rate at which the Lenders may now or in the future make
loans to other borrowers.

     2.11.  Substituted Interest Rate
            -------------------------

          In the event that (i) the Administrative Agent shall have determined
(which determination shall be conclusive and binding upon the Borrower) that by
reason of circumstances affecting the interbank eurocurrency market either
adequate and reasonable 

                                      -41-

 
means do not exist for ascertaining the Eurodollar Rate or the Alternate
Currency Euro Rate, as the case may be, applicable pursuant to Section 2.10 or
(ii) the Required Lenders shall have notified the Administrative Agent that they
have determined (which determination shall be conclusive and binding on the
Borrower) that the applicable Eurodollar Rate or Alternate Currency Euro Rate,
as the case may be, will not adequately and fairly reflect the cost to such
Lenders of maintaining or funding loans bearing interest based on such
Eurodollar Rate or Alternate Currency Euro Rate, as the case may be, with
respect to any portion of the Loans that the Borrower has requested be made as
Eurodollar Advances or Alternate Currency Advances, as the case may be, or
Eurodollar Advances or Alternate Currency Advances, as the case may be, that
will result from the requested conversion or continuation of any portion of the
Advances into or as Eurodollar Advances or Alternate Currency Advances, (each,
an "Affected Advance"), the Administrative Agent shall promptly notify the
    ---------------- 
Borrower and the Lenders (by telephone or otherwise, to be promptly confirmed in
writing) of such determination and the reasons therefor, on or, to the extent
practicable, prior to the requested Borrowing Date or Conversion/Continuation
Date for such Affected Advances. If the Administrative Agent shall give such
notice, (a) in the case of Eurodollar Advances, (A) any Affected Advances shall
be made as ABR Advances, (B) the Advances (or any portion thereof) that were to
have been converted to or continued as Affected Advances shall be converted to
or continued as ABR Advances and (C) any outstanding Affected Advances shall be
converted, on the last day of the then current Interest Period with respect
thereto, to ABR Advances, and (b) in the case of Alternate Currency Advances,
the interest rate for such Affected Advances shall be determined pursuant to
clause (a)(iii) of the definition of Alternate Currency Euro Rate. Until any
notice under clauses (i) or (ii), as the case may be, of this Section has been
withdrawn by the Administrative Agent (by notice to the Borrower and the Lenders
promptly upon either (x) the Administrative Agent having determined that such
circumstances affecting the interbank eurocurrency market no longer exist and
that adequate and reasonable means do exist for determining the Eurodollar Rate
or Alternate Currency Euro Rate, as the case may be, pursuant to Section 2.10 or
(y) the Administrative Agent having been notified by such Required Lenders that
circumstances no longer render the Advances (or any portion thereof) Affected
Advances), (1) no further Eurodollar Advances shall be required to be made by
the Lenders, (2) the Borrower shall not have the right to convert or continue
all or any portion of the Loans to or as Eurodollar Advances, and (3) the
interest rate for Alternate Currency Advances shall be determined pursuant to
clause (a)(iii) of the definition of Alternate Currency Euro Rate.

     2.12. Taxes
           -----

          (a) Payments to Be Free and Clear. Subject to Sections 2.12(d),
              -----------------------------                              
2.12(e) and 2.12(f), all payments by each Credit Party under the Loan Documents
shall be made free and clear of, and without any deduction or withholding for,
any Indemnified Tax.  If any Credit Party or any other Person is required by any
law, rule, regulation, order, directive, treaty or guideline to make any
deduction or withholding (which deduction or withholding would constitute an
Indemnified Tax) from any amount required to be paid by any Credit Party to or
on behalf of any Indemnified Tax Person under any Loan Document (each a
                                                                       
"Required Payment"), then:
- -----------------         

          (i) such Credit Party shall notify the Administrative Agent and such
Indemnified Tax Person of any such requirement or any change in any such
requirement as soon as such Credit Party becomes aware thereof;

                                      -42-

 
          (ii) such Credit Party shall pay such Indemnified Tax prior to the
date on which penalties attach thereto, such payment to be made (to the extent
that the liability to pay is imposed on such Credit Party) for its own account
or (to the extent that the liability to pay is imposed on such Indemnified Tax
Person) on behalf and in the name of such Indemnified Tax Person;

          (iii)  such Credit Party shall pay to such Indemnified Tax Person an
additional amount such that such Indemnified Tax Person shall receive on the due
date therefor  an amount equal to the Required Payment had no such deduction or
withholding been required; and

          (iv) such Credit Party shall, within 30 days after paying such
Indemnified Tax, deliver to the Administrative Agent and such Indemnified Tax
Person satisfactory evidence of such payment to the relevant Governmental
Authority.

          (b) Other Indemnified Taxes. If any Indemnified Tax Person or any
              -----------------------                                      
affiliate thereof is required by any law, rule, regulation, order, directive,
treaty or guideline to pay any Indemnified Tax (excluding an Indemnified Tax
which is subject to Section 2.12(a)) with respect to any sum paid or payable by
any Credit Party to such Indemnified Tax Person under the Loan Documents, then,
within five days after such Indemnified Tax Person shall have notified such
Credit Party thereof (which notice shall be accompanied by a statement setting
forth the reasonable calculation thereof), such Credit Party shall pay to such
Indemnified Tax Person the amount of such Indemnified Tax.

          (c) Tax on Indemnified Taxes. If any amounts are payable by any Credit
              ------------------------                                          
Party in respect of Indemnified Taxes pursuant to Section 2.12(a) or (b), such
Credit Party agrees to pay to the applicable Indemnified Tax Person, within five
days of written request therefor (which request shall set forth the reasonable
calculations thereof), an amount equal to all Taxes imposed with respect to such
amounts as such Indemnified Tax Person shall determine in good faith are payable
by such Indemnified Tax Person or any affiliate thereof in respect of such
amounts and in respect of any amounts paid to or on behalf of such Indemnified
Tax Person pursuant to this Section 2.12(c).

          (d) Exception for Existing Taxes. No amount shall be required to be
              ----------------------------                                   
paid to any Indemnified Tax Person under Section 2.12(a) or (b) with respect to
any Indemnified Tax to the extent that such Indemnified Tax would have been
required to have been paid under any law, rule, regulation, order, directive,
treaty or guideline in effect on the Relevant Date.

          (e) U.S. Tax Certificates. Each Lender that is organized under the
              ---------------------                                         
laws of any jurisdiction other than the United States or any political
subdivision thereof shall deliver to the Administrative Agent for transmission
to the Borrower, on or prior to the Relevant Date, and at such other times as
may be necessary in the determination of the Borrower, any other Credit Party or
the Administrative Agent (each in the reasonable exercise of its discretion),
such certificates, documents or other evidence, properly completed and duly
executed by such Lender (including Internal Revenue Service Form 1001 or Form
4224 (or, in each case, any equivalent or successor form)) to establish that
such Lender is not subject to deduction or withholding of United States federal
income tax under Section 1441 or 1442 of the Code or otherwise (or under any
comparable provisions 

                                      -43-

 
of any successor statute) with respect to any payments to such Lender of
principal, interest, fees or other amounts payable under the Loan Documents or
in the case of a Lender that is claiming an exemption from United States
withholding tax under Section 871(h) or 881(c) of the Internal Revenue Code with
respect to payments of "portfolio interest" two accurate and complete signed
original Forms W-8 (or any successor form prescribed by the Internal Revenue
Service, certifying that such Lender is exempt from United States withholding
tax on payments under this Agreement or the Notes) and, if such Lender delivers
such Forms W-8 (or successor form), two signed certificates that such Lender is
not (1) a "bank" for purposes of Section 881(c) of the Internal Revenue Code,
(2) is not a 10% shareholder (within the meaning of Section 871(h)(3)(B) of the
Internal Revenue Code) of the Borrower and (3) is not a controlled foreign
corporation related to the Borrower (within the meaning of Section 864(d)(4) of
the Internal Revenue Code). No Credit Party shall be required to pay any
additional amount to any such Lender under Section 2.12(a)(iii) if such Lender
shall have failed to satisfy the requirements of the immediately preceding
sentence; provided that, if such Lender shall have satisfied such requirements
on the Relevant Date, nothing in this Section 2.12(e) shall relieve any Credit
Party of its obligation to pay any additional amounts pursuant to Section
2.12(a)(iii) in the event that, as a result of any change in applicable law
(including any change in the interpretation thereof), such Lender is no longer
properly entitled to deliver certificates, forms, documents or other evidence at
a subsequent date establishing the fact that such Lender is not subject to
deduction or withholding as described in the immediately preceding sentence.

          (f) Other Tax Certificates. Each Indemnified Tax Person agrees to use
              ----------------------                                           
reasonable efforts to deliver to any Credit Party or the Administrative Agent,
promptly upon any reasonable request therefor from time to time by such Credit
Party or the Administrative Agent, such certificates, forms, documents and
information as may be required by applicable law, regulation, order, directive,
guideline or treaty from time to time and to file all appropriate forms to
obtain a certificate, form or other appropriate documents from the appropriate
Governmental Authorities to establish that payments made in respect of any
Alternate Currency Advance by such Credit Party can be made without (or at a
reduced rate of) deduction or withholding of Indemnified Taxes, provided,
                                                                -------- 
however, that if such Indemnified Tax Person is or becomes unable by virtue of

any change in applicable law, regulation or treaty, to establish such exemption
or reduction, such Credit Party shall nonetheless remain obligated under Section
2.12(a) to pay the amounts described therein, and provided further that no
                                                  -------- -------        
Indemnified Tax Person shall be required to take any action under this Section
2.12(f) which, in the sole discretion of such Indemnified Tax Person, would
cause such Indemnified Tax Person or any affiliate thereof to suffer a material
economic, legal or regulatory disadvantage.

          (g) Other Taxes. Each Credit Party agrees to pay any current or future
              -----------                                                       
stamp or documentary taxes or any other excise or property taxes, charges or
similar levies that arise from any payment made hereunder or from the execution,
delivery or registration of, or any amendment, supplement or modification of, or
any waiver or consent under or in respect of, the Loan Documents or otherwise
with respect to, the Loan Documents.

          (h) Refunds.  Upon the reasonable request of a Credit Party, and at
              -------                                                        
such Credit Party's expense, each Indemnified Tax Person shall cooperate with
such Credit Party in seeking to obtain refunds of Taxes paid by such Credit
Party, provided that each 

                                      -44-

 
such Indemnified Tax Person shall have no obligation to (i) engage in any
litigation, hearing or proceeding with respect thereto or (ii) disclose any tax
return or other confidential information other than information reasonably
requested by the applicable taxing authority which, in the opinion of such
Indemnified Tax Person, is not detrimental to such Indemnified Tax Person. If an
Indemnified Tax Person shall receive a refund (or a refund in the form of a
credit) from a taxing authority (as a result of any error in the imposition of
Tax by such taxing authority) of any Taxes paid by such Credit Party pursuant to
this Section 2.12, such Indemnified Tax Person, so long as no Event of Default
shall then exist, shall promptly pay to such Credit Party the amount so
received.

     2.13.  Illegality
            ----------

          Notwithstanding any other provisions herein, if any law, regulation,
treaty or directive, or any change therein or in the interpretation or
application thereof, in each case enacted, adopted, promulgated, approved or
issued after the date hereof, shall make it unlawful for any Lender to make or
maintain its Eurodollar Advances or Alternate Currency Advances as contemplated
by this Agreement, (i) the commitment of such Lender hereunder to (A) make
Eurodollar Advances or Alternate Currency Advances as the case may be, (B)
convert ABR Advances to Eurodollar Advances or (C) continue Eurodollar Advances
or Alternate Currency Advances, as the case may be, to new Eurodollar Advances
or Alternate Currency Advances, as the case may be, shall forthwith be
suspended, (ii) such Lender's Loans then outstanding as Eurodollar Advances
affected hereby, if any, shall be converted automatically to ABR Advances on the
last day of the then current Interest Period applicable thereto or within such
earlier period as required by law, and (iii) with respect to such Lender's
outstanding Alternate Currency Advances affected hereby, the Borrower shall take
such actions as such Lender may reasonably request (including, without
limitation, repaying such Alternate Currency Advances) with a view to minimizing
the obligations of the Borrower under Section 2.15.  If the commitment of any
Lender with respect to Eurodollar Advances or Alternate Currency Advances is
suspended pursuant to this Section and such Lender shall notify the
Administrative Agent and the Borrower that it is once again legal for such
Lender to make or maintain Eurodollar Advances or Alternate Currency Advances,
as the case may be, such Lender's commitment to make or maintain Eurodollar
Advances or Alternate Currency Advances, as the case may be, shall be
reinstated.

     2.14.  Increased Costs
            ---------------

          In the event that any law, regulation, treaty or directive hereafter
enacted, adopted, promulgated, approved or issued or any change in any existing
law, regulation, treaty or directive or in the interpretation or application
thereof by any Governmental Authority charged with the administration thereof or
compliance by any Lender (or any Person directly or indirectly owning or
controlling such Lender) with any request or directive from any central bank or
other Governmental Authority made or issued after the date hereof:

          (a) does or shall subject any Lender to any Taxes of any kind
whatsoever with respect to any Eurodollar Advances or any Alternate Currency
Advances or its obligations under this Agreement to make Eurodollar Advances or
Alternate 

                                      -45-

 
Currency Advances, or change the basis of taxation of payments to any Lender of
principal, interest or any other amount payable hereunder in respect of its
Eurodollar Advances or Alternate Currency Advances, including any Taxes required
to be withheld from any amounts payable under the Loan Documents (except for
imposition of, or change in the rate of, Tax on the Income of such Lender or its
Applicable Lending Office for any of such Advances by the jurisdiction in which
such Lender is incorporated or has its principal office or such Applicable
Lending Office, including, in the case of Lenders incorporated in any State of
the United States, such tax imposed by the United States); or

          (b) does or shall impose, modify or make applicable any reserve,
special deposit, compulsory loan, assessment, increased cost or similar
requirement against assets held by, or deposits of, or advances or loans by, or
other credit extended by, or any other acquisition of funds by, any office of
such Lender in respect of its Eurodollar Advances or Alternate Currency Advances
that is not otherwise included in the determination of a Eurodollar Rate or
Alternate Currency Euro Rate, as the case may be;

and the result of any of the foregoing is to increase the cost to such Lender of
making, renewing, converting, continuing or maintaining its Eurodollar Advances
or Alternate Currency Advances or its commitment to make such Eurodollar
Advances or Alternate Currency Advances, or to reduce any amount receivable
hereunder in respect of its Eurodollar Advances or Alternate Currency Advances,
then, in any such case, the Borrower shall pay such Lender, upon its demand, any
additional amounts necessary to compensate such Lender for such additional cost
or reduction in such amount receivable that such Lender deems to be material as
determined by such Lender; provided, however, that nothing in this Section shall
require the Borrower to indemnify the Lenders with respect to Taxes for which
the Borrower has no obligation under Section 2.12.  No failure by any Lender to
demand compensation for any increased cost during any Interest Period shall
constitute a waiver of such Lender's right to demand such compensation at any
time.  A statement setting forth the calculations of any additional amounts
payable pursuant to the foregoing sentence submitted by a Lender to the Borrower
shall be conclusive absent manifest error.

     2.15.  Indemnification for Loss
            ------------------------

          Notwithstanding anything contained herein to the contrary, if (i) the
Borrower shall fail to borrow or convert or continue a Eurodollar Advance or an
Alternate Currency Advance on a Borrowing Date or Conversion/Continuation Date
after it shall have given notice to do so in which it shall have requested a
Eurodollar Advance or an Alternate Currency Advance, as the case may be, or if
the Borrower shall fail to borrow a Swing Line Loan after it shall have agreed
to a Negotiated Rate with respect thereto, (ii) a Eurodollar Advance or an
Alternate Currency Advance or Swing Line Loan bearing interest at a Negotiated
Rate shall be terminated for any reason prior to the last day of the Interest
Period applicable thereto, or (iii) while a Eurodollar Advance or an Alternate
Currency Advance or Swing Line Loan bearing interest at a Negotiated Rate is
outstanding, any repayment or prepayment of such Eurodollar Advance, Alternate
Currency Advance or Swing Line Loan is made for any reason (including, without
limitation, as a result of acceleration or illegality) on a date which is prior
to the last day of the Interest Period applicable thereto, the Borrower agrees
to indemnify each Lender against, and to pay on demand directly to such Lender,
any loss or expense suffered by such Lender as a result of such failure to
borrow, convert or continue, termination, repayment or prepayment, including,
without limitation, an amount, if greater than zero, equal to:

                                      -46-

 
                               A x (B-C) x  D/360

where:

"A" equals, in the case of a Eurodollar Advance or an Alternate Currency
Advance, such Lender's Commitment Percentage of the Affected Principal Amount
or, in the case of a Swing Line Loan bearing interest at a Negotiated Rate, the
Affected Principal Amount;

"B" equals the Eurodollar Rate, Alternate Currency Euro Rate or Negotiated Rate,
as the case may be (expressed as a decimal), applicable to such Eurodollar
Advance, Alternate Currency Advance or Swing Line Loan;

"C" equals the applicable Eurodollar Rate or Alternate Currency Euro Rate, as
the case may be (expressed as a decimal), in effect on or about the first day of
the applicable Remaining Interest Period, based on the applicable rates offered
or bid, as the case may be, on or about such date, for deposits in an amount
equal approximately to such Lender's Commitment Percentage of the Affected
Principal Amount, or the rate (expressed as a decimal), as determined by the
Swing Line Lender, which the Swing Line Lender in good faith would have offered
as a Negotiated Rate on or about the first day of the applicable Remaining
Interest Period with respect to an amount equal approximately to the Affected
Principal Amount, as the case may be, in each case, with an Interest Period
equal approximately to the applicable Remaining Interest Period, as determined
by such Lender; and

"D" equals the number of days from and including the first day of the applicable
Remaining Interest Period to but excluding the last day of such Remaining
Interest Period;

and any other out-of-pocket loss or expense (including any internal processing
charge customarily charged by such Lender) suffered by such Lender in connection
with such Eurodollar Advance, Alternate Currency Advance or Swing Line Loan
bearing interest at a Negotiated Rate to the extent based on a Negotiated Rate,
as the case may be, including, without limitation, in liquidating or employing
deposits acquired to fund or maintain the funding of its Commitment Percentage
of the Affected Principal Amount, or redeploying funds prepaid or repaid, in
amounts that correspond to its Commitment Percentage of the Affected Principal
Amount or, in the case of a Swing Line Loan bearing interest at a Negotiated
Rate, the amount of such Swing Line Loan.  Each determination by the
Administrative Agent or a Lender pursuant to this Section shall be conclusive
and binding on the Borrower absent manifest error.

     2.16.  Option to Fund
            --------------

          Each Lender has indicated that, if the Borrower requests a Eurodollar
Advance, an Alternate Currency Advance or Swing Line Loan, such Lender may wish
to purchase one or more deposits in order to fund or maintain its funding of
such Eurodollar Advance, Alternate Currency Advance or Swing Line Loan during
the Interest Period in question; it being understood that the provisions of this
Agreement relating to such funding are included only for the purpose of
determining the rate of interest to be paid on such Eurodollar Advance,
Alternate Currency Advance or Swing Line Loan and for purposes of determining
amounts owing under Sections 2.14, 2.15 and 2.18.  Each Lender shall be entitled
to fund and maintain its funding of all or any part of each Eurodollar Advance,
Alternate Currency Advance or Swing Line Loan made by it in any manner it 

                                      -47-

 
sees fit, but all such determinations shall be made as if such Lender had
actually funded and maintained its funding of such Eurodollar Advance, Alternate
Currency Advance or Swing Line Loan during the applicable Interest Period
through the purchase of deposits in an amount equal to such Eurodollar Advance,
Alternate Currency Advance or Swing Line Loan and having a maturity
corresponding to such Interest Period. The obligations of the Borrower under
Sections 2.11, 2.12, 2.13, 2.14, 2.15, 2.18 and 2.22 shall survive the
termination of the Aggregate Revolving Credit Commitments, the payment of the
Notes, the reimbursement obligations in respect of drawings under Letters of
Credit and all other amounts payable under the Loan Documents.

     2.17.  Use of Proceeds
            ---------------

          The proceeds of the Loans shall be used for Permitted Acquisitions and
the general corporate purposes of the Borrower and its Subsidiaries.
Notwithstanding anything to the contrary contained in any Loan Document, the
Borrower agrees that no part of the proceeds of any Loan will be used, directly
or indirectly, for a purpose that violates any law, including, without
limitation, the provisions of Regulations G, U or X of the Board of Governors of
the Federal Reserve System, as amended.

     2.18.  Capital Adequacy
            ----------------

          If (i) the enactment or promulgation of, or any change or phasing in
of, any United States or foreign law or regulation or in the interpretation
thereof by any Governmental Authority charged with the administration thereof
after the date hereof or (ii) compliance with any directive or guideline from
any central bank or United States or foreign Governmental Authority (whether
having the force of law) promulgated or made after the date hereof, affects or
would affect the amount of capital required to be maintained by a Lender (or any
lending office of such Lender) or any Person directly or indirectly owning or
controlling such Lender, or imposes any restriction on or otherwise adversely
affects such Lender (or any lending office of such Lender) or any Person
directly or indirectly owning or controlling such Lender, and such Lender shall
have determined that such enactment, promulgation, change or compliance has the
effect of reducing the rate of return on such Lender's (or such Person's)
capital or the asset value to such Lender of any Loan made by, or any Letter of
Credit issued or participated in by, such Lender as a consequence, directly or
indirectly, of its obligations to make and maintain the funding of its Loans and
Letters of Credit at a level below that which such Lender (or such Person) could
have achieved but for such enactment, promulgation, change or compliance (after
taking into account such Lender's policies (or such Person's) regarding capital
adequacy) by an amount deemed by such Lender to be material, then, upon demand
by such Lender, the Borrower shall promptly pay to such Lender such additional
amount or amounts as shall be sufficient to compensate such Lender (or such
Person) for such reduction in such rate of return or asset value.  A certificate
in reasonable detail as to such amounts submitted to the Borrower and the
Administrative Agent setting forth the determination of such amount or amounts
that will compensate such Lender for such reductions shall be presumed correct
absent manifest error.

     2.19.  Letter of Credit Sub-Facility
            -----------------------------

          (a) Subject to the terms and conditions of this Agreement, the Letter
of Credit Issuer agrees, in reliance on the agreement of the other Lenders set
forth in Section 

                                      -48-

 
2.20, to issue standby letters of credit (the "Letters of Credit";
                                               -----------------
each, individually, a "Letter of Credit") in Dollars or in an Alternate
                       ----------------                                         
Currency during the Revolving Credit Commitment Period for the account of the
Borrower, provided that immediately after the issuance of each Letter of Credit,
(i) the Letter of Credit Exposure of all Lenders at any one time shall not
exceed $100,000,000, (ii) the Aggregate Credit Exposure shall not exceed the
Aggregate Revolving Credit Commitments and (iii) the Aggregate Alternate
Currency Exposure shall not exceed $125,000,000. Each Letter of Credit issued
pursuant to this Section shall have a termination date that shall be not later
than the earlier of one year from the date of issuance or 5 days prior to the
Maturity Date. At the request of the Borrower, and upon 3 Business Days' prior
written notice to the Administrative Agent, and provided that no Default or
Event of Default shall then exist, each Letter of Credit termination date may be
extended, from time to time, for a period not to exceed the earlier of (i) one
year or (ii) the 5th day prior to the Maturity Date. No Letter of Credit shall
be issued if the Administrative Agent, or any Lender by notice to the
Administrative Agent no later than 1:00 P.M. one Business Day prior to the
requested date of issuance of such Letter of Credit, shall have determined that
the conditions set forth in Section 6 have not been satisfied.

          (b) Each Letter of Credit shall be issued for the account of the
Borrower in support of an obligation of the Borrower or a Subsidiary of the
Borrower in favor of a beneficiary who has requested the issuance of such Letter
of Credit as a condition to a transaction entered into in connection with the
Borrower's ordinary course of business.  The Borrower shall give the
Administrative Agent a Letter of Credit Request for the issuance of each Letter
of Credit by (A) in the case of a Letter of Credit denominated in Dollars, 2:00
P.M., three Business Days prior to the requested date of issuance, and (B) in
the case of an Alternate Currency Letter of Credit, 2:00 P.M., ten Business Days
prior to the requested date of issuance.  Such Letter of Credit Request shall be
accompanied by the Letter of Credit Issuer's standard Application and Agreement
for Standby Letter of Credit (each, a "Reimbursement Agreement") executed by an
                                       -----------------------                 
Authorized Signatory of the Borrower and shall specify (i) the beneficiary of
such Letter of Credit and the obligations of the Borrower or a Subsidiary of the
Borrower in respect of which such Letter of Credit is to be issued, (ii) the
Borrower's proposal as to the conditions under which a drawing may be made under
such Letter of Credit and the documentation to be required in respect thereof,
(iii) the Currency of, and the maximum amount to be available under, such Letter
of Credit, and (iv) the requested date of issuance.  Upon receipt of such Letter
of Credit Request from the Borrower, the Administrative Agent shall promptly
notify the Letter of Credit Issuer and each Lender thereof.  The Letter of
Credit Issuer shall, on the proposed date of issuance and subject to the other
terms and conditions of this Agreement, issue the requested Letter of Credit.
Each Letter of Credit shall be in form and substance reasonably satisfactory to
the Letter of Credit Issuer, with such provisions with respect to the conditions
under which a drawing may be made thereunder and the documentation required in
respect of such drawing as the Letter of Credit Issuer shall reasonably require.
Each Letter of Credit shall be used solely for the purposes described therein.

          (c) Each payment by the Letter of Credit Issuer of a draft drawn under
a Letter of Credit shall give rise to an obligation on the part of the Borrower
to reimburse the Letter of Credit Issuer immediately for the amount thereof in
the same Currency as such Letter of Credit is denominated.

                                      -49-

 
     2.20.  Letter of Credit Participation and Funding Commitments
            ------------------------------------------------------

          (a) Each Lender hereby unconditionally and irrevocably, severally for
itself only and without any notice to or the taking of any action by such
Lender, takes an undivided participating interest in the obligations of the
Letter of Credit Issuer under and in connection with each Letter of Credit in an
amount equal to such Lender's Commitment Percentage of the amount of such Letter
of Credit.  Each Lender shall be liable to the Letter of Credit Issuer for its
Commitment Percentage of the unreimbursed amount of any draft drawn and honored
under each Letter of Credit.  Each Lender shall also be liable for an amount
equal to the product of its Commitment Percentage and any amounts paid by the
Borrower pursuant to Section 2.21 that are subsequently rescinded or avoided or
must otherwise be restored or returned.  Such liabilities shall be unconditional
and without regard to the occurrence of any Default or Event of Default or the
compliance by the Borrower with any of its obligations under the Loan Documents,
provided, however, that no Lender shall have any liability to the Letter of
Credit Issuer under this Section 2.20 for any payment under a Letter of Credit
to the extent made as a result of the Letter of Credit Issuer's gross negligence
or willful misconduct.

          (b) The Administrative Agent will promptly notify each Lender (which
notice shall be promptly confirmed in writing) of the date and the amount and
Currency of any draft presented under any Letter of Credit with respect to which
full reimbursement of payment is not made by the Borrower as provided in Section
2.19(c), and forthwith upon receipt of such notice, such Lender (other than the
Letter of Credit Issuer) shall make available to the Administrative Agent for
the account of the Letter of Credit Issuer its Commitment Percentage of the
amount of such unreimbursed draft at the office of the Administrative Agent
specified in Section 11.2, in the same Currency as such Letter of Credit is
denominated and in immediately available funds, before 4:00 P.M., on the day
such notice was given by the Administrative Agent, if the relevant notice was
given by the Administrative Agent at or prior to 1:00 P.M., on such day, or
before 12:00 Noon, on the next Business Day, if the relevant notice was given by
the Administrative Agent after 1:00 P.M., on such day.  The Administrative Agent
shall distribute the payments made by each Lender (other than the Letter of
Credit Issuer) pursuant to the immediately preceding sentence to the Letter of
Credit Issuer promptly upon receipt thereof in like funds as received.  Each
Lender shall indemnify and hold harmless the Administrative Agent and the Letter
of Credit Issuer from and against any and all losses, liabilities (including
liabilities for penalties), actions, suits, judgments, demands, costs and
expenses (including, without limitation, reasonable attorneys' fees and
expenses) resulting from any failure on the part of such Lender to provide, or
from any delay in providing, the Administrative Agent with such Lender's
Commitment Percentage of the amount of any payment made by the Letter of Credit
Issuer under a Letter of Credit in accordance with this clause (b) above (except
in respect of losses, liabilities or other obligations suffered by the
Administrative Agent or the Letter of Credit Issuer resulting from the gross
negligence or willful misconduct of the Letter of Credit Issuer).  If a Lender
does not make available to the Administrative Agent when due such Lender's
Commitment Percentage of any unreimbursed payment made by the Letter of Credit
Issuer under a Letter of Credit (other than payments made by the Letter of
Credit Issuer by reason of its gross negligence or willful misconduct), such
Lender shall be required to pay interest to the Administrative Agent for the
account of the Letter of Credit Issuer, from the date such Lender's payment is
due until the date such payment is received by the Administrative Agent, on such
Lender's Commitment Percentage of such payment at a rate of interest per annum
equal to (i) from the date such 

                                      -50-

 
amount was due until the third day therefrom, the Federal Funds Rate, and (ii)
thereafter, the Federal Funds Rate plus 1%. The Administrative Agent shall
distribute such interest payments to the Letter of Credit Issuer upon receipt
thereof in like funds as received.

          (c) Whenever the Administrative Agent is reimbursed by the Borrower,
for the account of the Letter of Credit Issuer, for any payment under a Letter
of Credit and such payment relates to an amount previously paid by a Lender in
respect of its Commitment Percentage of the amount of such payment under such
Letter of Credit, the Administrative Agent will pay over such payment to such
Lender (i) before 4:00 P.M. on the day such payment from the Borrower is
received, if such payment is received at or prior to 1:00 P.M. on such day, or
(ii) before 12:00 Noon on the next succeeding Business Day, if such payment from
the Borrower is received after 1:00 P.M. on such day.

     2.21.  Absolute Obligation with respect to Letter of Credit Payments
            -------------------------------------------------------------

          The Borrower's obligation to reimburse the Administrative Agent for
the account of the Letter of Credit Issuer in respect of a Letter of Credit for
each payment under or in respect of such Letter of Credit shall be absolute and
unconditional under any and all circumstances and irrespective of any set-off,
counterclaim or defense to payment that the Borrower may have or have had
against the beneficiary of such Letter of Credit, the Administrative Agent, the
Letter of Credit Issuer, any Lender or any other Person, including, without
limitation, any defense based on the failure of any drawing to conform to the
terms of such Letter of Credit, any drawing document proving to be forged,
fraudulent or invalid, or the legality, validity, regularity or enforceability
of such Letter of Credit; provided, however, that the Borrower shall not be
obligated to reimburse the Administrative Agent for the account of the Letter of
Credit Issuer for any wrongful payment under such Letter of Credit to the extent
made as a result of the Letter of Credit Issuer's gross negligence or willful
misconduct.

     2.22.  Increased Costs Based on Letters of Credit
            ------------------------------------------

          Without limiting the provisions of Section 2.14, if any law or
regulation adopted or enacted after the date hereof or any change after the date
hereof in the interpretation or application thereof by any Governmental
Authority charged with the administration thereof shall either (a) impose,
modify or make applicable any reserve, special deposit, assessment or similar
requirement against letters of credit issued or participated in by the Letter of
Credit Issuer or any Lender, or (b) impose on the Administrative Agent, the
Letter of Credit Issuer or such Lender any other condition regarding the Letters
of Credit (except for imposition of, or changes in the rate of, Tax on the
Income of the Administrative Agent, the Letter of Credit Issuer  or such Lender)
and the result of any event referred to in clause (a) or (b) above shall be to
increase the cost to the Letter of Credit Issuer or any such Lender of issuing
or maintaining the Letters of Credit or its obligations pursuant to Section
2.20, or the cost to the Administrative Agent of performing its functions
hereunder with respect to the Letters of Credit, in any case by an amount that
the Administrative Agent, the Letter of Credit Issuer, or any Lender, as the
case may be, deems material, then, upon demand by the Administrative Agent, the
Letter of Credit Issuer or such Lender, as the case may be, the Borrower shall
immediately pay to the Administrative Agent, the Letter of Credit Issuer or such
Lender, as the case may be, from time to time as specified by the Administrative

                                      -51-

 
Agent, the Letter of Credit Issuer or such Lender, additional amounts that shall
be sufficient to compensate the Administrative Agent, the Letter of Credit
Issuer or such Lender, as the case may be, for such increased cost.  A statement
in reasonable detail as to such increased cost incurred by the Administrative
Agent, the Letter of Credit Issuer or such Lender, as the case may be, as a
result of any event mentioned in clauses (a) or (b) above, submitted by the
Administrative Agent, the Letter of Credit Issuer or such Lender, as the case
may be, to the Borrower shall be conclusive, absent manifest error, as to the
amount thereof.

     2.23.  Administrative Agent's Records
            ------------------------------

          The Administrative Agent's records regarding the amount of each Loan
and Letter of Credit, each payment by the Borrower of principal and interest on
the Loans and reimbursement obligations in respect of Letters of Credit and
other information relating to the Loans shall be presumptively correct absent
manifest error.


3.   FEES; PAYMENTS
     --------------

     3.1. Commitment Fee
          --------------

          (a) The Borrower agrees to pay to the Administrative Agent, for the
account of the Lenders in accordance with each Lender's Commitment Percentage, a
fee (the "Commitment Fee") for each day during the period from and including the
          --------------                                                        
Effective Date to, but excluding, the Maturity Date, equal to (a) the excess of,
for each day during the Revolving Credit Commitment Period, the Aggregate
Revolving Credit Commitments on such day over the sum of the aggregate
outstanding principal balance of the Revolving Credit Loans and the Letter of
Credit Exposure of all Lenders on such day (excluding the outstanding principal
balance of the Swing Line Loans, Alternate Currency Revolving Credit Loans and
Alternate Currency Letters of Credit, if any) multiplied by  (b) the percentage
set forth below for the applicable pricing level in effect on such day:

 
 
                                    Commitment
      Pricing Level                 Fee Percentage
      -------------                 --------------
                                  
      When the Leverage Ratio
      is equal to or greater
      than 4.00:1.00                0.375%

      When the Leverage Ratio
      is less than 4.00:1.00

      than 3.75:1.00                0.375%

      When the Leverage Ratio
      is less than 3.50:1.00
      but equal to or greater
      than 3.00:1.00                0.300%

      When the Leverage Ratio
      is less than 3.00:1.00
      but equal to or greater
      than 2.50:1.00                0.250%

      When the Leverage Ratio

      When the Leverage Ratio
      is less than 1.00:1.00        0.175%
 

          (b) Changes in the Commitment Fee resulting from a change in the
Leverage Ratio, as evidenced by a Compliance Certificate delivered to the
Administrative Agent pursuant to Section 7.1(c) evidencing such a change, shall
become effective upon delivery of such Compliance Certificate.  If the Borrower
shall fail to deliver a Compliance Certificate in accordance with Section 7.1(c)
(each a "certificate delivery date"), for purposes of calculating the Commitment
Fee, the Leverage Ratio from and including such certificate delivery date to the
date of delivery by the Borrower to the Administrative Agent of such Compliance
Certificate shall be conclusively presumed to be greater than 4.00:1.00.

          (c) The Commitment Fee shall be payable quarterly in arrears on the
last day of each March, June, September and December of each year, commencing on
the first such day following the Effective Date, on any date the Aggregate
Revolving Credit Commitments are reduced pursuant to Section 2.6, and on the
Maturity Date.  The Commitment Fee shall be calculated on the basis of a 360-day
year for the actual number of days elapsed.

          (d) Notwithstanding the foregoing (but subject to the last sentence of
subsection (b) above), until such time as the Compliance Certificate for the
fiscal quarter ending June 30, 1998 shall have been delivered to the
Administrative Agent, the Commitment Fee percentage shall be equal to 0.300%,
provided that if the Compliance 

                                      -53-

 
Certificate delivered to the Administrative Agent for the fiscal quarter ending
March 31, 1998 indicates a Leverage Ratio equal to or greater than 3.50:1.00,
then the Applicable Margin for the period from the delivery of such Compliance
Certificate to the delivery of the Compliance Certificate for the fiscal quarter
ending June 30, 1998 shall be the applicable Commitment Fee percentage for such
Leverage Ratio set forth in subsection (a) above.

     3.2. Letter of Credit Fees
          ---------------------

          (a) The Borrower agrees to pay to the Administrative Agent, for the
account of the Lenders in accordance with each Lender's Commitment Percentage, a
fee (the "Letter of Credit Fee") with respect to each Letter of Credit for the
          --------------------                                                
period from and including the date of issuance thereof to and including the
expiration date thereof, at the LC Rate on the maximum amount available to be
drawn (under any contingency) under such Letter of Credit (determined, in the
case of each Alternate Currency Letter of Credit, on the basis of the Dollar
Equivalent thereof) on such day.

          (b) The Borrower further agrees to pay to the Letter of Credit Issuer,
for its own account, a fee (the "LC Fronting Fee") with respect to each Letter
                                 ---------------                              
of Credit for each day during the period from and including the date of issuance
thereof to and including the expiration date thereof, at a rate per annum equal
to 0.075% on the maximum amount available to be drawn (under any contingency)
under such Letter of Credit (determined, in the case of each Alternate Currency
Letter of Credit, on the basis of the Dollar Equivalent thereof) on such day.

          (c) The Letter of Credit Fee and the LC Fronting Fee shall be (i)
calculated on the basis of a 360-day year for the actual number of days elapsed,
(ii) payable quarterly in arrears on the last day of each March, June, September
and December of each year and on the Maturity  Date and (iii) nonrefundable.  In
addition to the Letter of Credit Fee and the LC Fronting Fee, the Borrower
agrees to pay to the Letter of Credit Issuer, for its own account, its standard
fees and charges customarily charged to customers similar to the Borrower with
respect to any Letter of Credit.

     3.3. Pro Rata Treatment and Application of Principal Payments
          --------------------------------------------------------

          (a) Each payment, including each prepayment, of principal and interest
on the Loans and of the Commitment Fee and the Letter of Credit Fee shall be
made by the Borrower without set-off or counterclaim and shall be made to the
Administrative Agent in the applicable Currency at the applicable Agent Payment
Office in funds immediately available to the Administrative Agent at such office
by 1:30 P.M. (local time in the city in which the applicable Agent Payment
Office is located) on the due date for such payment, and, promptly upon receipt
thereof by the Administrative Agent, shall be remitted by the Administrative
Agent, in like funds as received, (i) to the Lenders according to the Commitment
Percentage of each Lender, in the case of the Commitment Fee and the Letter of
Credit Fee, (ii) to the Lenders pro rata according to the aggregate outstanding
principal balance of the Revolving Credit Loans, in the case of principal and
interest due on the Revolving Credit Loans and (iii) to the Swing Line Lender in
the case of principal and interest due on the Swing Line Loan.  Notwithstanding
the foregoing, each payment of the Existing Revolving Credit Loans, interest,
fees and other amounts made pursuant to Section 5.14 shall be distributed to the
Non-Continuing Lenders and the Existing Lenders 

                                      -54-

 
in accordance with Section 3.3 of the Existing Revolving Credit Agreement. The
failure of the Borrower to make any such payment by such time shall not
constitute a default hereunder, provided that such payment is made on such due
date, but any such payment made after 1:30 P.M. on such due date shall be deemed
to have been made on the next Business Day for the purpose of calculating
interest on amounts outstanding on the Loans. If any payment hereunder or under
the Notes shall be due and payable on a day that is not a Business Day, the due
date thereof (except as otherwise provided in the definition of Interest Period)
shall be extended to the next Business Day and (except with respect to payments
in respect of the Commitment Fee and the Letter of Credit Fee) interest shall be
payable at the applicable rate specified herein during such extension. If any
payment is made with respect to any Eurodollar Advance or Alternate Currency
Advance prior to the last day of the applicable Interest Period, the Borrower
shall indemnify each Lender in accordance with Section 2.15.

          (b) Notwithstanding anything to the contrary contained in any Loan
Document, each payment (including each prepayment) of principal and interest on
each Alternate Currency Revolving Credit Loan shall be made solely in the
Currency in which such Alternate Currency Revolving Credit Loan is denominated.


4.   REPRESENTATIONS AND WARRANTIES
     ------------------------------

     In order to induce the Administrative Agent and the Lenders to enter into
this Agreement and to make the Revolving Credit Loans, the Letter of Credit
Issuer to issue the Letters of Credit and the Lenders to participate therein,
and the Swing Line Lender to make the Swing Line Loans and the Lenders to
participate therein, the Borrower makes the following representations and
warranties to the Administrative Agent and each Lender:

     4.1. Subsidiaries; Capitalization
          ----------------------------

          The Borrower has only the Subsidiaries permitted by this Agreement.
Schedule 4.1 sets forth the Subsidiaries of the Borrower as of the Effective
Date.  The shares of each corporate Subsidiary are duly authorized, validly
issued, fully paid and nonassessable and are owned free and clear of any Liens.
The interest of the Borrower in each non-corporate Subsidiary is owned free and
clear of any Liens.  The outstanding capital Stock of each corporate Subsidiary
of the Borrower on the Effective Date and the ownership interest in each non-
corporate Subsidiary are as set forth on Schedule 4.1.  As of the Effective
Date, the owner of each issue of capital Stock listed on Schedule 4.1 is the
registered and beneficial owner thereof.  No Subsidiary has issued any
securities convertible into Stock (or other equity interest) of such Subsidiary
and there are no outstanding options or warrants to purchase Stock of such
Subsidiary of any class or kind, and there are no voting trusts or similar
agreements with respect thereto or other agreements or understandings with
respect thereto which would restrict or limit the sale, pledge, assignment or
other disposition thereof, including, without limitation, any right of first
refusal, option, redemption, call or other rights with respect thereto, whether
similar or dissimilar to any of the foregoing, or which would dilute the
interest of the Borrower therein.

                                      -55-

 
     4.2. Existence and Power
          -------------------

          Each of the Borrower, its Subsidiaries and the Credit Parties is duly
organized or formed and validly existing in good standing under the laws of the
jurisdiction of its incorporation or formation, has all requisite power and
authority to own its Property and to carry on its business as now conducted, and
is in good standing and authorized to do business as a foreign corporation in
each jurisdiction in which the nature of the business conducted therein or the
Property owned therein makes such qualification necessary, except in each case
where such failure so to qualify could not reasonably be expected to have a
Material Adverse Effect.

     4.3. Authority
          ---------

          Each of the Borrower, its Subsidiaries and the Credit Parties has full
legal power and authority to enter into, execute, deliver and perform the terms
of the Loan Documents to which it is a party, and the transactions contemplated
thereby (including the Transactions) and, in the case of the Borrower, to make
the borrowings contemplated hereby and by the Notes, to execute, deliver and
carry out the terms of the Notes and to incur the obligations provided for
herein and therein, all of which have been duly authorized by all proper and
necessary corporate or other applicable action and are in full compliance with
its Certificate of Incorporation or By-Laws or its other organization documents.

     4.4. Binding Agreement
          -----------------

          The Loan Documents (other than the Notes) constitute, and the Notes,
when issued and delivered pursuant hereto for value received, will constitute,
the valid and legally binding obligations of the Credit Parties in each case, to
the extent it is a party thereto, enforceable in accordance with their
respective terms, except as such enforceability may be limited by applicable
bankruptcy, insolvency, reorganization, moratorium  or other similar laws
affecting the enforcement of creditors' rights generally.

     4.5. Litigation
          ----------

          Except as set forth on Schedule 4.5, there are no actions, suits or
proceedings at law or in equity or by or before any Governmental Authority
(whether purportedly on behalf of the Borrower, any of its Subsidiaries or any
Credit Party) pending or, to the knowledge of the Borrower, threatened against
the Borrower, any of its Subsidiaries or any Credit Party or any of their
respective Properties or rights, that (i) if adversely determined, could
reasonably be expected to have a Material Adverse Effect, (ii) expressly call
into question the validity or enforceability of any of the Loan Documents, or
(iii) could reasonably be expected to result in the rescission, termination or
cancellation of any material franchise, right, license, permit or similar
authorization held by the Borrower or any of its Subsidiaries or any Credit
Party.

     4.6. Required Consents
          -----------------

          Except for information filings required to be made in the ordinary
course of business that are not a condition to the Borrower's performance under
the Loan Documents, no consent, authorization or approval of, filing with,
notice to, or exemption by, 

                                      -56-

 
stockholders, any Governmental Authority or any other Person is required to
authorize, or is required in connection with the execution, delivery and
performance of the Loan Documents and the transactions contemplated thereby
(including the Transactions), or is required as a condition to the validity or
enforceability of the Loan Documents.

     4.7. No Conflicting Agreements
          -------------------------

          Neither the Borrower, any of its Subsidiaries nor any Credit Party is
in default under any mortgage, indenture, contract or agreement to which it is a
party, or by which it or any of its Property is bound, the effect of which
default could reasonably be expected to have a Material Adverse Effect.  The
execution, delivery or carrying out of the terms of the Loan Documents and the
transactions contemplated hereby and thereby (including the Transactions), will
not constitute a default under, or result in the creation or imposition of, or
obligation to create, any Lien upon any Property of the Borrower or any of its
Subsidiaries or result in a breach of or require the mandatory repayment of or
other acceleration of payment under or pursuant to the terms of any such
mortgage, indenture, contract or agreement.

     4.8. Compliance with Applicable Laws
          -------------------------------

          Neither the Borrower, any of its Subsidiaries nor any Credit Party is
in default with respect to any judgment, order, writ, injunction, decree or
decision of any Governmental Authority the effect of which default could
reasonably be expected to have a Material Adverse Effect.  The Borrower, each of
its Subsidiaries and each Credit Party is complying in all material respects
with all statutes, regulations, rules and orders applicable to Borrower, such
Subsidiary or such Credit Party of all Governmental Authorities, including,
without limitation, Environmental Laws and ERISA, the violation of which could
reasonably be expected to have a Material Adverse Effect, provided that this
sentence shall not extend to matters relating to compliance with federal
Medicaid and Medicare statutes or the regulations promulgated pursuant to such
statutes or related state or local statutes or regulations to the extent such
matters are covered by Sections 4.20 and 4.21.

     4.9. Taxes
          -----

          Except as provided on Schedule 4.9, all tax returns required to be
filed by or on behalf of the Borrower, its Subsidiaries and each Credit Party
have been filed and payment, and adequate provision for the payment, has been
made for all taxes shown to be due and payable on said returns or in any
assessments made against the Borrower, its Subsidiaries or any Credit Party
(other than those being contested as required under Section 7.4) that would be
material to the Borrower or its Subsidiaries taken as a whole, and no tax liens
(other than a Permitted Lien described in Section 8.2(i)) have been filed with
respect to the Borrower, its Subsidiaries or any Credit Party.  The charges,
accruals and reserves on the books of the Borrower, each of its Subsidiaries and
each Credit Party with respect to all federal, state, local and other taxes are,
to the best knowledge of the Borrower, adequate for the payment of all such
material taxes, and the Borrower knows of no unpaid assessment that is due and
payable against it, any of its Subsidiaries or any Credit Party or any claims
being asserted that could reasonably be expected to have a Material Adverse
Effect, except such thereof as are being contested as required under Section
7.4, and for which adequate reserves have been set aside in accordance with
GAAP.

                                      -57-

amended, the Federal Power Act or the Investment Company Act of 1940, as
amended, and neither the Borrower, any of its Subsidiaries nor any Credit Party
is subject to any statute or regulation that prohibits or restricts the
incurrence of Indebtedness under the Loan Documents, including, without
limitation, statutes or regulations relative to common or contract carriers or
to the sale of electricity, gas, steam, water, telephone, telegraph or other
public utility services.

     4.11.  Federal Reserve Regulations; Use of Proceeds
            --------------------------------------------

engaged principally, or as one of its important activities, in the business of
extending credit for the purpose of purchasing or carrying any Margin Stock.  No
part of the proceeds of the Loans or Letters of Credit will be used, directly or
indirectly, for a purpose that violates any law, rule or regulation of any
Governmental Authority, including, without limitation, the provisions of
Regulations G, T, U or X of the Board of Governors of the Federal Reserve
System, as amended.  No part of the proceeds of the Loans or Letters of Credit
will be used, directly or indirectly, to purchase or carry Margin Stock or to
extend credit to others for the purpose of purchasing or carrying Margin Stock.

            -----

          The only Pension Plans in effect as of the Effective Date (the
"Existing Pension Plans") are listed on Schedule 4.12.  Each Employee Benefit
- -----------------------                                                      
Plan of the Borrower, its Subsidiaries, the Credit Parties and the ERISA
Affiliates is in compliance with ERISA and the Code, where applicable, in all
material respects.  As of the Effective Date (i) the amount of all Unfunded
Pension Liabilities under the Pension Plans, excluding any plan that is a
Multiemployer Plan, does not exceed $0, and (ii) the amount of the aggregate
Unrecognized Retiree Welfare Liability under all applicable Employee Benefit
Plans does not exceed $100,000.  Each of the Borrower, its Subsidiaries, the
Credit Parties and the ERISA Affiliates has complied with the requirements of
Section 515 of ERISA with respect to each Pension Plan that is a Multiemployer
Plan.  As of the Effective Date, the aggregate potential annual withdrawal
liability payments, as determined in accordance with Title IV of ERISA, of the
Borrower, its Subsidiaries, the Credit Parties and the ERISA Affiliates with
respect to all Pension Plans that are Multiemployer Plans is approximately $0.
Each of the Borrower, its Subsidiaries, the Credit Parties and/or any ERISA
Affiliate has, as of the Effective Date, made all material contributions or
payments to or under each such Pension Plan required by law or the terms of such
Pension Plan or any contract or agreement with respect thereto.  No material
liability to the PBGC has been, or is expected by the Borrower, any of its
Subsidiaries, any Credit Party or any ERISA Affiliate to be, incurred by the
Borrower, such Subsidiary, such Credit Party or any ERISA Affiliate.  Liability,
as referred to in this Section includes any joint and several liability.  Each
Employee Benefit Plan that is a group health plan within the meaning of Section
5000(b)(1) of the Code is in material compliance with the continuation of health
care coverage requirements of Section 4980B of the Code.

the Lenders copies of the audited consolidated balance sheet of the Borrower as
of December 31, 1997 and the related consolidated statements of income, retained
earnings and cash flows for the fiscal year then ended (with the related notes
and schedules, the "Financial Statements").  The Financial Statements fairly
                    --------------------                                    
present the consolidated financial condition and results of the operations of
the Borrower and its Subsidiaries, as the case may be, as of the dates and for
the periods indicated therein and have been prepared in conformity with GAAP.
As of the Effective Date, except as reflected in the Financial Statements or in
the notes thereto, neither the Borrower nor any of its Subsidiaries has any
obligation or liability of any kind (whether fixed, accrued, contingent,
unmatured or otherwise) that, in accordance with GAAP, should have been shown on
the Financial Statements and was not.  Since the date of the Financial
Statements there has been no Material Adverse Change.

     4.14.  Property
            --------

          Each of the Borrower, its Subsidiaries and each Credit Party has good
and marketable title to all of its Property, title to which is material to the
Borrower and its Subsidiaries taken as a whole, subject to no Liens, except for
Permitted Liens.

     4.15.  Franchises, Intellectual Property, Etc.

          Each of the Borrower, its Subsidiaries and each Credit Party possesses
or has the right to use all franchises, Intellectual Property, licenses and
other rights as are material and necessary for the conduct of its business, and
with respect to which it is in compliance, with no known conflict with the valid
rights of others that would reasonably be expected to have a Material Adverse
Effect.  No event has occurred that permits or, to the best knowledge of the
Borrower, after notice or the lapse of time or both, or any other condition,
could reasonably be expected to permit, the revocation or termination of any
such franchise, Intellectual Property, license or other right which revocation
or termination could reasonably be expected to have a Material Adverse Effect.

     4.16.  Environmental Matters
            ---------------------

          (a) The Borrower, each of its Subsidiaries and each Credit Party is in
material compliance with the requirements of all applicable Environmental Laws.

          (b) No Hazardous Substances have been generated or manufactured on,
transported to or from, treated at, stored at or discharged from any Real
Property in material violation of any Environmental Laws; no Hazardous
Substances have been discharged into subsurface waters under any Real Property
in material violation of any Environmental Laws; no Hazardous Substances have
been discharged from any Real Property on or into Property or waters (including
subsurface waters) adjacent to any Real Property in material violation of any
Environmental Laws; and there are not now, nor ever have been, on any Real
Property any underground or above ground storage tanks in material violation of
any Environmental Laws.

          (c) Neither the Borrower, nor any of its Subsidiaries or any Credit
Party (i) has received notice (written or oral) or otherwise learned of any
claim, demand, 

                                      -59-

 
suit, action, proceeding, event, condition, report, directive, Lien, violation,
non-compliance or investigation indicating or concerning any potential or actual
material liability (including, without limitation, potential material liability
for enforcement, investigatory costs, cleanup costs, government response costs,
removal costs, remedial costs, natural resources damages, Property damages,
personal injuries or penalties) arising in connection with: (x) any non-
compliance with or violation of the requirements of any applicable Environmental
Laws, or (y) the presence of any Hazardous Substance on any Real Property (or
any Real Property previously owned by the Borrower, any of its Subsidiaries or
any Credit Party) or the release or threatened release of any Hazardous
Substance into the environment, (ii) has knowledge of any threatened or actual
material liability in connection with the presence of any Hazardous Substance on
any Real Property (or any Real Property previously owned by the Borrower, any of
its Subsidiaries or any Credit Party) or the release or threatened release of
any Hazardous Substance into the environment, (iii) has received notice of any
federal or state investigation evaluating whether any material remedial action
is needed to respond to the presence of any Hazardous Substance on any Real
Property (or any Real Property previously owned by the Borrower, any of its
Subsidiaries or any Credit Party) or a release or threatened release of any
Hazardous Substance into the environment for which the Borrower, any of its
Subsidiaries or any Credit Party is or may be liable, or (iv) has received
notice that the Borrower, any of its Subsidiaries or any Credit Party is or may

"material" shall mean any liability or potential liability of the Borrower and
its Subsidiaries on a Consolidated basis for an aggregate amount in excess of
$1,000,000.

     4.17.  Labor Relations
            ---------------

          There are no material controversies pending between the Borrower, any
of its Subsidiaries or any Credit Party and any of their respective employees,
that could reasonably be expected to have a Material Adverse Effect.

     4.18.  Burdensome Obligations
            ----------------------

          Neither the Borrower, any of its Subsidiaries nor any Credit Party is
a party to or bound by any franchise, agreement, deed, lease or other
instrument, or subject to any restriction that, in the opinion of the management
of the Borrower, is so unusual or burdensome, in the context of its business, as
in the foreseeable future might materially and adversely affect or impair the
revenue or cash flow of the Borrower and its Subsidiaries taken as a whole, or
the ability of the Borrower or its Subsidiaries taken as a whole to perform its,
or their, obligations under the Loan Documents to which it is, or they are, a
party.  The Borrower does not presently anticipate that future expenditures by
the Borrower, any of its Subsidiaries or any Credit Party needed to meet the
provisions of federal or state statutes, orders, rules or regulations will be so
burdensome as to result in a Material Adverse Effect or Material Adverse Change.

     4.19.  Medicare Participation/Accreditation
            ------------------------------------

          The facilities operated by the Borrower and its Subsidiaries (the

programs (together with 

                                      -60-

 
their respective intermediaries or carriers, the "Government Reimbursement
                                                  ------------------------
Programs") and are entitled to reimbursement under the Medicare program for
- --------
services rendered to qualified Medicare beneficiaries, and comply in all
material respects with the conditions of participation in all Government
Reimbursement Programs. There is no pending or, to Borrower's knowledge,
threatened proceeding or investigation by any of the Government Reimbursement
Programs, or for reimbursement of amounts due or to become due to the facilities
from the Government Reimbursement Programs.

     4.20.  Fraud and Abuse
            ---------------

respective officers or directors has, on behalf of the Borrower or any of its
Subsidiaries, knowingly or wilfully violated the federal Medicare and Medicaid
statutes, 42 U.S.C. (S)1320a-7b, or the regulations promulgated pursuant to such

of any other amounts owing to the Administrative Agent, the Letter of Credit
Issuer and the Lenders under any Loan Document.


10.  THE ADMINISTRATIVE AGENT
     ------------------------

   10.1.  Appointment
          -----------

          Each Lender hereby irrevocably designates and appoints BNY as the
Administrative Agent of such Lender under the Loan Documents and each such
Lender hereby irrevocably authorizes BNY, as the Administrative Agent for such
Lender, to take such action on its behalf under the provisions of the Loan
Documents (including, without limitation, the Intercreditor Agreement) and to
exercise such powers and perform such duties as are expressly delegated to the
Administrative Agent by the terms of the Loan Documents, together with such
other powers as are reasonably incidental thereto.  Notwithstanding any
provision to the contrary elsewhere in any Loan Document, the Administrative
Agent shall not have any duties or responsibilities other than those expressly
set forth therein, or any fiduciary relationship with any Lender, and no implied

                                       87

 
covenants, functions, responsibilities, duties, obligations or liabilities shall
be read into the Loan Documents or otherwise exist against the Administrative
Agent.

   10.2.  Delegation of Duties
          --------------------

          The Administrative Agent may execute any of its duties under the Loan
Documents by or through agents or attorneys-in-fact and shall be entitled to
rely upon the advice of counsel concerning all matters pertaining to such
duties.

   10.3.  Exculpatory Provisions
          ----------------------

          Neither the Administrative Agent nor any of its officers, directors,
employees, agents, attorneys-in-fact or affiliates shall be (i) liable for any
action lawfully taken or omitted to be taken by the Administrative Agent or such
Person under or in connection with the Loan Documents (except the Administrative
Agent or such Person for its own gross negligence or willful misconduct), or
(ii) responsible in any manner to any of the Lenders for any recitals,
statements, representations or warranties made by any Credit Party or any
officer thereof contained in the Loan Documents or in any certificate, report,
statement or other document referred to or provided for in, or received by the
Administrative Agent under or in connection with, the Loan Documents or for the
value, validity, effectiveness, genuineness, perfection, enforceability or
sufficiency of any of the Loan Documents or for any failure of any Credit Party
or any other Person to perform its obligations thereunder.  The Administrative
Agent shall not be under any obligation to any Lender to ascertain or to inquire
as to the observance or performance of any of the agreements contained in, or
conditions of, the Loan Documents, or to inspect the properties, books or
records of any Credit Party.  The Administrative Agent shall not be under any
liability or responsibility whatsoever, as Administrative Agent, to any Credit
Party or any other Person as a consequence of any failure or delay in
performance, or any breach, by any Lender of any of its obligations under any of
the Loan Documents.

   10.4.  Reliance by Administrative Agent
          --------------------------------

          The Administrative Agent shall be entitled to rely, and shall be fully
protected in relying, upon any writing, resolution, notice, consent,
certificate, affidavit, opinion, letter, cablegram, telegram, fax, telex or
teletype message, statement, order or other document or conversation believed by
it to be genuine and correct and to have been signed, sent or made by the proper
Person or Persons and upon advice and statements of legal counsel (including,
without limitation, counsel to any Credit Party), independent accountants and
other experts selected by the Administrative Agent.  The Administrative Agent
may treat each Lender, or the Person designated in the last notice filed with it
under this Section, as the holder of all of the interests of such Lender in its
Loans and in its Notes until written notice of transfer, signed by such Lender
(or the Person designated in the last notice filed with the Administrative
Agent) and by the Person designated in such written notice of transfer, in form
and substance satisfactory to the Administrative Agent, shall have been filed
with the Administrative Agent.  The Administrative Agent shall not be under any
duty to examine or pass upon the validity, effectiveness, enforceability,
perfection or genuineness of the Loan Documents or any instrument, document or
communication furnished pursuant thereto or in connection therewith, and the
Administrative Agent shall be entitled to assume that the same are valid,
effective and genuine, have been signed or sent by the proper parties and are
what they purport to be.  The Administrative 

                                       88

 
Agent shall be fully justified in failing or refusing to take any action under
the Loan Documents unless it shall first receive such advice or concurrence of
the Required Lenders as it deems appropriate. The Administrative Agent shall in
all cases be fully protected in acting, or in refraining from acting, under the
Loan Documents in accordance with a request or direction of the Required Lenders
(or, when expressly required by a Loan Document, all the Lenders), and such
request or direction and any action taken or failure to act pursuant thereto
shall be binding upon all the Lenders and all future holders of the Notes.

   10.5.  Notice of Default
          -----------------

          The Administrative Agent shall not be deemed to have knowledge or
notice of the occurrence of any Default or Event of Default unless the
Administrative Agent has received written notice thereof from a Lender or the
Borrower.  In the event that the Administrative Agent receives such a notice,
the Administrative Agent shall promptly give notice thereof to the Lenders, the
Letter of Credit Issuer and the Borrower.  The Administrative Agent shall take
such action with respect to such Default or Event of Default as shall be
directed by the Required Lenders, provided, however, 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 or Event of Default as it shall
deem to be in the best interests of the Lenders.

   10.6.  Non-Reliance on Administrative Agent and Other Lenders
          ------------------------------------------------------

          Each Lender expressly acknowledges that neither the Administrative
Agent nor any of its respective officers, directors, employees, agents,
attorneys-in-fact or affiliates has made any representations or warranties to it
and that no act by the Administrative Agent hereafter, including any review of
the affairs of any Credit Party, shall be deemed to constitute any
representation or warranty by the Administrative Agent to any Lender.  Each
Lender represents to the Administrative Agent that it has, independently and
without reliance upon the Administrative Agent or any other Lender, and based on
such documents and information as it has deemed appropriate, made its own
evaluation of and investigation into the business, operations, Property,
financial and other condition and creditworthiness of the Credit Parties and
made its own decision to enter into this Agreement.  Each Lender also represents
that it will, independently and without reliance upon the Administrative Agent
or any other Lender, and based on such documents and information as it shall
deem appropriate at the time, continue to make its own credit analysis,
evaluations and decisions in taking or not taking action under any Loan
Document, and to make such investigation as it deems necessary to inform itself
as to the business, operations, Property, financial and other condition and
creditworthiness of the Credit Parties.  Except for notices, reports and other
documents expressly required to be furnished to the Lenders by the
Administrative Agent hereunder, the Administrative Agent shall not have any duty
or responsibility to provide any Lender with any credit or other information
concerning the business, operations, Property, financial and other condition or
creditworthiness of the Credit Parties that may come into the possession of the
Administrative Agent or any of its officers, directors, employees, agents,
attorneys-in-fact or affiliates.

                                       89

 
   10.7.  Indemnification
          ---------------

          Each Lender agrees to indemnify and reimburse the Administrative Agent
in its capacity as such (to the extent not promptly reimbursed by the Borrower
and without limiting the obligation of any Credit Party to do so), according to
its Commitment Percentage, from and against any and all liabilities,
obligations, claims, losses, damages, penalties, actions, judgments, suits,
costs, expenses or disbursements of any kind whatsoever, including, without
limitation, any amounts paid to the Lenders (through the Administrative Agent)
by the Borrower pursuant to the terms of the Loan Documents that are
subsequently rescinded or avoided or must otherwise be restored or returned,
that may at any time (including, without limitation, at any time following the
payment of the Loans) be imposed on, incurred by or asserted against the
Administrative Agent in any way relating to or arising out of the Loan Documents
or any other documents contemplated by or referred to therein or the
transactions contemplated thereby or any action taken or omitted to be taken by
the Administrative Agent under or in connection with any of the foregoing;
provided, however, that no Lender shall be liable for the payment of any portion
of such liabilities, obligations, losses, damages, penalties, actions,
judgments, suits, costs, expenses or disbursements to the extent resulting from
the gross negligence or willful misconduct of the Administrative Agent.  The
agreements in this Section shall survive the payment of all amounts payable
under the Loan Documents.

   10.8.  Administrative Agent in Its Individual Capacity
          -----------------------------------------------

          BNY and its respective affiliates may make loans to, accept deposits
from, issue letters of credit for the account of, and generally engage in any
kind of business with, any Credit Party as though BNY were not Administrative
Agent hereunder.  With respect to the Commitment made or renewed by BNY and the
Notes issued to BNY, BNY shall have the same rights and powers under the Loan
Documents as any Lender and may exercise the same as though it were not the
Administrative Agent, and the terms "Lender" and "Lenders" shall in each case
include BNY.

   10.9.  Successor Administrative Agent
          ------------------------------

          If at any time the Administrative Agent deems it advisable, in its
sole discretion, it may submit to each of the Lenders a written notice of its
resignation as Administrative Agent under the Loan Documents, such resignation
to be effective upon the earlier of (i) the written acceptance of the duties of
the Administrative Agent under the Loan Documents by a successor Administrative
Agent and (ii) on the 30th day after the date of such notice.  Upon any such
resignation, the Required Lenders shall have the right to appoint from among the
Lenders a successor Administrative Agent.  If no successor Administrative Agent
shall have been so appointed by the Required Lenders and accepted such
appointment in writing within 30 days after the retiring Administrative Agent's
giving of notice of resignation, then the retiring Administrative Agent may, on
behalf of the Lenders, appoint a successor Administrative Agent, which successor
Administrative Agent shall be a commercial bank organized under the laws of the
United States or any State thereof and having a combined capital, surplus, and
undivided profits of at least $100,000,000.  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's rights, powers,
privileges 

                                       90

 
and duties as Administrative Agent under the Loan Documents shall be terminated.
The Borrower and the Lenders shall execute such documents as shall be necessary
to effect such appointment. After any retiring Administrative Agent's
resignation as Administrative Agent, the provisions of the Loan Documents shall
inure to its benefit as to any actions taken or omitted to be taken by it while
it was Administrative Agent under the Loan Documents. If at any time there shall
not be a duly appointed and acting Administrative Agent, the Borrower agrees to
make each payment due under the Loan Documents directly to the Persons entitled
thereto during such time.

  10.10.  Appointment of Collateral Agent
          -------------------------------

          Each Lender hereby authorizes the Administrative Agent to enter into
the Intercreditor Agreement on behalf of and for the benefit of that Lender and
agrees to be bound by the terms of the Intercreditor Agreement.  Each Lender
hereby authorizes the Collateral Agent to enter into the Collateral Documents
and the Intercreditor Agreement and to accept the Subsidiary Guaranty and to
take all action contemplated by the Intercreditor Agreement, the Collateral
Documents, and Subsidiary Guaranty.  Each Lender agrees that no Lender shall
have any right individually to seek or to enforce the Subsidiary Guaranty or to
realize upon the security granted by any Collateral Document, it being
understood and agreed that such rights and remedies may be exercised by the
Collateral Agent for the benefit of the Lenders and the parties to the
Intercreditor Agreement upon the terms of the Subsidiary Guaranty, the
Collateral Documents and the Intercreditor Agreement.

  10.11.  The Co-Arrangers
          ----------------

          The Co-Arrangers shall have no duties or obligations under the Loan
Documents in their capacity as Co-Arrangers.

  10.12.  The Syndication Agent
          ---------------------

          The Syndication Agent shall have no duties or obligations under the
Loan Documents in its capacity as Syndication Agent.

  10.13.  The Documentation Agent
          -----------------------

          The Documentation Agent shall have no duties or obligations under the
Loan Documents in its capacity as Documentation Agent.


11.  OTHER PROVISIONS
     ----------------

   11.1.  Amendments and Waivers
          ----------------------

          With the written consent of the Required Lenders, the Administrative
Agent and the appropriate Credit Parties may, from time to time, enter into
written amendments, supplements or modifications of this Agreement, the Notes
and the Intercreditor Agreement and, with the consent of the Required Lenders,
the Administrative Agent on behalf of the Lenders may execute and deliver to any
such parties a written instrument waiving or a consent to a departure from, on
such terms and conditions as the 

                                       91

 
Administrative Agent may specify in such instrument, any of the requirements of
this Agreement, the Notes and the Intercreditor Agreement or any Default or

such amendment, supplement, modification or waiver shall change the  amount or
the time of payment of the Letter of Credit Fee or the LC Fronting Fee or change
any other term or provision that relates to the Letters of Credit; and

          (c) without the written consent of the Swing Line Lender, no such
amendment, supplement, modification or waiver shall change the Swing Line
Commitment or change any other term or provision that relates to the Swing Line
Commitment or the Swing Line Loans; and

          (d) without the written consent of the Administrative Agent, no such
amendment, supplement, modification or waiver shall amend, modify or waive any
provision of Section 10 or otherwise change any of the rights or obligations of
the Administrative Agent hereunder or under the other Loan Documents; and

          (e) notwithstanding anything to the contrary contained in this Section
11.1, (i) the Collateral Documents, the Intercreditor Agreement and the
Subsidiary Guaranty may only be amended in accordance with the terms thereof and
of the Intercreditor Agreement, and (ii) the Collateral Agent may, at any time
and from time to time without the consent of any one or more of the Lenders, (A)
release all or any of the obligations of any one or more Subsidiaries under the
Collateral Documents in connection with a disposition of such Subsidiary as
permitted by Section 8.3 or 8.7, and (B) release any Collateral or any security
interest therein in connection with any release specifically provided for in the
Collateral Documents.

          Any such amendment, supplement, modification or waiver shall apply
equally to each of the Lenders and shall be binding upon the parties to the
applicable Loan Document, the Lenders, the Letter of Credit Issuer, the
Administrative Agent and all future holders of the Notes.  In the case of any
waiver, the parties to the applicable Loan Document, the Lenders, the Letter of
Credit Issuer and the Administrative Agent shall be restored to their former
position and rights hereunder and under the outstanding Notes and other Loan
Documents to the extent provided for in such waiver, and any Default or Event 

                                       92

 
of Default waived shall not extend to any subsequent or other Default or Event
of Default, or impair any right consequent thereon. The Loan Documents may not
be amended orally or by any course of conduct.

remedy, power or privilege under any Loan Document shall operate as a waiver
thereof; nor shall any single or partial exercise of any right, remedy, power or

or the exercise of any other right, remedy, power or privilege.  The rights,
remedies, powers and privileges under the Loan Documents are cumulative and not
exclusive of any rights, remedies, powers and privileges provided by law.

   11.5.  Payment of Expenses and Taxes
          -----------------------------

          The Borrower agrees, promptly upon presentation of a statement or
invoice therefor, and whether any Loan is made (i) to pay or reimburse the
Administrative Agent, the Documentation Agent, the Syndication Agent and the Co-
Arrangers for all their out-of-pocket costs and expenses reasonably incurred in
connection with the development, preparation and execution of the Loan Documents
and any amendment, supplement or modification thereto (whether or not executed),
any documents prepared in connection therewith and the consummation of the
transactions contemplated thereby, including, without limitation, the reasonable
fees and disbursements of Special Counsel, (ii) to pay or reimburse the
Administrative Agent, the Documentation Agent, the Syndication Agent,  the Co-
Arrangers, the Letter of Credit Issuer, and the Lenders for all of their
respective costs and expenses, including, without limitation, reasonable fees
and disbursements of counsel (including allocated costs of internal counsel),
incurred in connection with (A) any Default or Event of Default and any
enforcement or collection proceedings resulting therefrom or in connection with
the negotiation of any restructuring or "work-out" (whether consummated or not)
of the obligations of the Credit Parties under any of the Loan Documents and (B)
the enforcement of this Section, (iii) to pay, indemnify, and hold the
Administrative Agent, the Documentation Agent, the Syndication Agent, the Co-
Arrangers, the Letter of Credit Issuer and each Lender harmless from and
against, any and all recording and filing fees and any and all liabilities with
respect to, or resulting from any delay in paying, stamp, excise and other
similar taxes, if any, that may be payable or determined to be payable in
connection with the execution and delivery of, or consummation of any of the
transactions contemplated by, or any amendment, supplement or modification of,
or any waiver or consent under or in respect of, the Loan Documents and any such
other documents, and (iv) to pay, indemnify and hold the Administrative Agent,

obligations, claims, losses, damages, penalties, actions, judgments, suits,
costs, expenses and disbursements of 

                                       94

 
any kind or nature whatsoever (including, without limitation, reasonable counsel
fees and disbursements) with respect to the enforcement and performance of the
Loan Documents, the use of the proceeds of the Loans and the enforcement and
performance of the provisions of any subordination agreement in favor of the
Administrative Agent and the Lenders (all the foregoing, collectively, the
"indemnified liabilities") and, if and to the extent that the foregoing
 -----------------------
indemnity may be unenforceable for any reason, the Borrower agrees to make the
maximum payment permitted or not prohibited under applicable law; provided,
however, that the Borrower shall have no obligation hereunder to pay indemnified
liabilities to the Administrative Agent, the Documentation Agent, the
Syndication Agent, the Co-Arrangers, the Letter of Credit Issuer or any Lender
to the extent arising from such indemnified party's gross negligence or willful
misconduct or claims between one indemnified party and another indemnified
party. The agreements in this Section shall survive the termination of the
Aggregate Revolving Credit Commitments and the Swing Line Commitment and the
payment of all amounts payable under the Loan Documents.

   11.6.  Lending Offices
          ---------------

          (a) Each Lender shall have the right at any time and from time to time
to transfer its Letter of Credit Exposure or Loans, as the case may be, to a
different office, provided that it shall promptly notify the Administrative
Agent and the Borrower of any such change of office.  Such office shall
thereupon become, with respect to its Loans, its Lender's Domestic Lending
Office, Eurodollar Lending Office or Alternate Currency Lending Office, as the
case may be, provided, however, that it shall not be entitled to receive any
greater amount under Sections 2.12, 2.14, 2.15, 2.18 or 2.22 as a result of any
such transfer to a different office than it would be entitled to immediately
prior thereto unless (i) such claim would have arisen even if such transfer had
not occurred, (ii) such transfer was made pursuant to subsection (b) below, or
(iii) such claims arose as a result of a change of law after such transfer.

          (b) The Letter of Credit Issuer and each Lender agrees that, upon the
occurrence of any event giving rise to any increased cost or indemnity under
Sections 2.12, 2.14, 2.15, 2.18 or 2.22 with respect to the Letter of Credit
Issuer or such Lender, as the case may be, it will, if requested by the
Borrower, use reasonable efforts (subject to its overall policy considerations)
to designate another office for any part of its Letter of Credit Exposure or
Loans affected by such event, provided that such designation is made on such
terms that the Letter of Credit Issuer or such Lender, as the case may be, and
its office suffer no economic, legal or regulatory disadvantage, with the object
of avoiding the consequence of the event giving rise to the operation of any
such Section.

   11.7.  Assignments and Participations
          ------------------------------

          (a) The Loan Documents shall be binding upon and inure to the benefit
of the Borrower, the Lenders, the Letter of Credit Issuer, the Administrative
Agent, all future holders of the Notes and their respective successors and
assigns, except that no Credit Party may assign, delegate or transfer any of its
rights or obligations under the Loan Documents without the prior written consent
of the Administrative Agent, the Letter of Credit Issuer and each Lender.

          (b) Each Lender shall have the right at any time, upon written notice
to the Administrative Agent of its intent to do so and the payment of a fee (the
"Assignment 
 ----------

                                       95

 
Fee") of $3,500 to the Administrative Agent by the assigning or assignee Lender,
- ---
to sell, assign, transfer or negotiate all or any part of such Lender's rights
and obligations under the Loan Documents (i) to one or more of the other
Lenders, (ii) with the prior written consent of the Swing Line Lender and the
Letter of Credit Issuer (excluding First Union National Bank) (which consents
shall not be unreasonably withheld or delayed), to one or more of its affiliates
or the affiliates or Approved Funds of one or more of the other Lenders, or
(iii) with the prior written consent of the Borrower, the Administrative Agent,
the Swing Line Lender and the Letter of Credit Issuer (excluding First Union
National Bank) (which consents shall not be unreasonably withheld or delayed, or
with respect to the Borrower, required during the continuance of an Event of
Default), to any other bank, insurance company, pension fund, mutual fund or
other financial institution or fund, which in the normal course of its business,
purchases loans such as the Loans, provided that each such sale, assignment,
transfer or negotiation (other than sales, assignments, transfers or
negotiations (x) to affiliates of such Lender or (y) of a Lender's entire
interest) shall be in a minimum amount of $5,000,000. In addition, during the 30
day period (or such shorter period as the Administrative Agent and the
Syndication Agent shall notify the Borrower) following the Effective Date,
assignments made by the Administrative Agent and the Syndication Agent
(excluding assignments of Revolving Credit Commitments held by them in an amount
equal to the Revolving Credit Commitments (as defined in the Existing Credit
Agreement) held by them under the Existing Credit Agreement on April 20, 1998)
shall not be subject to the $5,000,000 minimum size restriction or require
payment of the Assignment Fee. For each assignment, the parties to such
assignment shall execute and deliver to the Administrative Agent for its
acceptance an Assignment and Acceptance Agreement which the Administrative Agent
shall record in a register (the "Register") maintained by the Administrative
                                 --------
Agent on behalf of the Borrower, for the recordation of the names and addresses
of the Lenders and the Commitment of, and principal amount of the Loans owing
to, each Lender from time to time and the registered owners of the Obligation(s)
evidenced by the Note(s), the entries in the Register shall be presumptively
correct absent manifest error. Upon such execution, delivery, acceptance and
recording by the Administrative Agent, from and after the effective date
specified in such Assignment and Acceptance Agreement, the assignee thereunder,
if not already a Lender, shall be a party hereto and, to the extent provided in
such Assignment and Acceptance Agreement, the assignor Lender thereunder shall
be released from its obligations under the Loan Documents. The Borrower agrees
upon written request of the Administrative Agent and at the Borrower's expense
to execute and deliver (i) to such assignee, a Revolving Credit Note, dated the
date of the Assignor's Revolving Credit Note subject to such Assignment and
Acceptance Agreement, in an aggregate principal amount equal to the Loans
assigned to, and Commitment assumed by, such assignee and (ii) to such assignor
Lender, a Revolving Credit Note, dated the date of the Assignor's Revolving
Credit Note subject to such Assignment and Acceptance Agreement, in an aggregate
principal amount equal to the balance of such assignor Lender's Loans and
Commitment, if any, and each assignor Lender shall cancel and return to the
Borrower its existing Revolving Credit Note. Upon any such sale, assignment or
other transfer, the Commitments and the Commitment Percentages set forth in
Exhibit A shall be adjusted accordingly by the Administrative Agent.

          (c) Each Lender may grant participations in all or any part of its
Loans, its Note, its Letter of Credit Exposure and its Commitment to one or more
banks, insurance companies, financial institutions, pension fund, mutual funds
or funds which in the normal course of business purchase loans such as the
Loans, provided that (i) such 

                                       96

 
Lender's obligations under the Loan Documents shall remain unchanged, (ii) such
Lender shall remain solely responsible to the other parties to the Loan
Documents for the performance of such obligations, (iii) the Borrower, the
Administrative Agent, the Letter of Credit Issuer and the other Lenders shall
continue to deal solely and directly with such Lender in connection with such
Lender's rights and obligations under the Loan Documents and (iv) the voting
rights of any holder of any participation shall be limited to decisions that
require the consent of all Lenders as set forth in Section 11.1(a). The Borrower
acknowledges and agrees that any such participant shall for purposes of Sections
2.12, 2.14, 2.15, 2.18 and 2.22 be deemed to be a "Lender"; provided, however,
the Borrower shall not, at any time, be obligated to pay any participant in any
interest of any Lender hereunder any sum in excess of the sum that the Borrower
would have been obligated to pay to such Lender in respect of such interest had
such Lender not sold such participation.

          (d) If any (i) assignment is made pursuant to subsection (b) above or
(ii) participation is granted pursuant to subsection (c) above to any Person
that is not a U.S. Person, such Person shall furnish such certificates,
documents or other evidence to the Borrower and the Administrative Agent, in the
case of clause (i), and to the Borrower and the Lender that sold such
participation, in the case of clause (ii), as shall be required by Section
2.12(e).

          (e) No Lender shall, as between and among the Borrower, the
Administrative Agent, the Documentation Agent, the Syndication Agent, the Swing
Line Lender, the Letter of Credit Issuer and such Lender, be relieved of any of
its obligations under the Loan Documents as a result of any sale, assignment,
transfer or negotiation of, or granting of participations in, all or any part of
its Loans, its Letter of Credit Exposure, its Commitment or its Note, except
that a Lender shall be relieved of its obligations to the extent of any such
sale, assignment, transfer, or negotiation of all or any part of its Loans, its
Letter of Credit Exposure, its Commitment or its Note pursuant to subsection (b)
above.

          (f) Notwithstanding anything to the contrary contained in this
Section, any Lender may at any time or from time to time assign or pledge all or
any portion of its rights under the Loan Documents to (i) a Federal Reserve Bank
or (ii) if such Lender is a fund which in the normal course of its business
purchasers loans such as the Loans, to its lenders or a trustee under an
indenture for the benefit of its creditors, to secure such fund's obligations,
provided that any such assignment or pledge shall not release such assignor from
its obligations thereunder.

          (g) In the event that the Borrower shall request that Lenders enter
into any amendment, modification, consent or waiver with respect to this
Agreement or any other Loan Document, which amendment, modification, consent or
waiver cannot become effective without the consent of each Lender, and any
Lender elects not to enter into such amendment, modification, consent or waiver
(each such lender being a "Dissenting Lender"), then the Borrower shall have the
right upon 10 days' written notice to the Administrative Agent and such
Dissenting Lender, to require each such Dissenting Lender to assign 100% of its
Revolving Credit Loans, Revolving Credit Notes and Revolving Credit Commitment
at par to any Lender or any other financial institution which satisfies the
requirements of Section 11.7(b) and has been consented to by the Administrative
Agent, the Swing Line Lender and the Letter of Credit Issuer (excluding First
Union National Bank (which consents shall not be unreasonably withheld or
delayed), in each 

                                       97

 
case that agrees, in its sole discretion, to assume such Revolving Credit Loans,
Revolving Credit Notes and Revolving Credit Commitment. Each such assignment
shall be made pursuant to an Assignment and Acceptance Agreement and shall
comply with the other terms of this Section 11.7. The Borrower shall pay to such
Dissenting Lender, concurrently with the effectiveness of such assignment, any
amounts payable under Section 2.15 that would have been payable if the Borrower
had voluntarily prepaid such Revolving Credit Loans. The Dissenting Lender shall
not be required to pay the Assignment Fee.

   11.8.  Counterparts; Effectiveness
          ---------------------------

          Each Loan Document (other than the Notes) may be executed by one or
more of the parties thereto on any number of separate counterparts and all of
said counterparts taken together shall be deemed to constitute one and the same
document.  It shall not be necessary in making proof of any Loan Document to
produce or account for more than one counterpart signed by the party to be
charged.  A counterpart of any Loan Document or of any amendment, modification,
consent or waiver to or of any Loan Document transmitted by fax shall be deemed
to be an originally executed counterpart.  A set of the copies of the Loan
Documents signed by all the parties thereto shall be deposited with each of the
Borrower and the Administrative Agent.  Any party to a Loan Document may rely
upon the signatures of any other party thereto that are transmitted by fax or
other electronic means to the same extent as if originally signed.  On the
Effective Date, at the time of the effectiveness of this Agreement, (i) this
Agreement shall amend and restate the Existing Revolving Credit Agreement, (ii)
all Existing Revolving Credit Loans outstanding under the Existing Revolving
Credit Agreement shall continue as and constitute Revolving Credit Loans for all
purposes under this Agreement, (iii) all Swing Line Loans (under and as defined
in the Existing Revolving Credit Agreement) shall continue as and constitute
Swing Line Loans for all purposes under this Agreement, (iv) all Letters of
Credit (under and as defined in the Existing Credit Agreement) shall continue as
and constitute Letters of Credit for all purposes under this Agreement, and (v)
all obligations of the Borrower under the Existing Revolving Credit Agreement
that have not been paid as of the Effective Date shall become Obligations of the
Borrower under this Agreement.

   11.9.  Adjustments; Set-off
          --------------------

          (a) If any Lender shall at any time receive any payment of all or any
part of its Loans, or interest thereon, or receive any collateral in respect
thereof (whether voluntarily or involuntarily, by set-off, pursuant to events or
proceedings of the nature referred to in Section 9.1 (h) or (i), or otherwise)
in a greater proportion than any such payment to and collateral received by any
other Lender in respect of such other Lender's Loans, or interest thereon (each
a "Benefited Lender"), such Benefited Lender shall purchase for cash from each
   ----------------                                                           
of the other Lenders such portion of each such other Lender's Loans, and shall
provide each of such other Lenders with the benefits of any such collateral, or
the proceeds thereof, as shall be necessary to cause such Benefited Lender to
share the excess payment or benefits of such collateral or proceeds ratably with
each of the Lenders, provided, however, that if all or any portion of such
excess payment or benefits is thereafter recovered from such Benefited Lender,
such purchase shall be rescinded, and the purchase price and benefits returned,
to the extent of such recovery, but without interest.  The Borrower agrees that
each Lender so purchasing a portion of another Lender's Loans may exercise all
rights of payment (including, without limitation, rights of set-off, 

                                       98

 
to the extent not prohibited by law) with respect to such portion as fully as if
such Lender were the direct holder of such portion.

          (b) In addition to any rights and remedies of the Lenders provided by
law, upon the occurrence of an Event of Default and the acceleration of the
obligations owing in connection with the Loan Documents, or at any time upon the
occurrence and during the continuance of an Event of Default, under Section
9.1(a) or (b), each Lender shall have the right, without prior notice to the
Borrower, any such notice being expressly waived by each Credit Party to the
extent not prohibited by applicable law, to set-off and apply against any
indebtedness, whether matured or unmatured, of such Credit Party to such Lender,
any amount owing from such Lender to such Credit Party, at, or at any time
after, the happening of any of the above-mentioned events.  To the extent not
prohibited by applicable law, the aforesaid right of set-off may be exercised by
such Lender against such Credit Party or against any trustee in bankruptcy,
custodian, debtor in possession, assignee for the benefit of creditors,
receiver, or execution, judgment or attachment creditor of such Credit Party, or
against anyone else claiming through or against such Credit Party or such
trustee in bankruptcy, custodian, debtor in possession, assignee for the benefit
of creditors, receiver, or execution, judgment or attachment creditor,
notwithstanding the fact that such right of set-off shall not have been
exercised by such Lender prior to the making, filing or issuance, or service
upon such Lender of, or of notice of, any such petition, assignment for the
benefit of creditors, appointment or application for the appointment of a
receiver, or issuance of execution, subpoena, order or warrant.  Each Lender
agrees promptly to notify the applicable Credit Party and the Administrative
Agent after any such set-off and application made by such Lender, provided that
the failure to give such notice shall not affect the validity of such set-off
and application.

  11.10.  Construction
          ------------

          Each Credit Party represents that it has been represented by counsel
in connection with the Loan Documents and the transactions contemplated thereby
and that the principle that agreements are to be construed against the draftsman
shall be inapplicable.

  11.11.  Indemnity
          ---------

          The Borrower agrees to indemnify and hold harmless the Administrative
Agent, the Documentation Agent, the Syndication Agent, the Co-Arrangers, the
Letter of Credit Issuer and each Lender and their respective affiliates,
directors, officers, employees, attorneys and agents (each an "Indemnified
                                                               -----------
Person") from and against any loss, cost, liability, damage or expense
- ------                                                                
(including the reasonable fees and disbursements of counsel of such Indemnified
Person, including all local counsel hired by any such counsel) incurred by such
Indemnified Person in investigating, preparing for, defending against, or
providing evidence, producing documents or taking any other action in respect
of, any commenced or threatened litigation, administrative proceeding or
investigation under any federal securities law or any other statute of any
jurisdiction, or any regulation, or at common law or otherwise, that is alleged
to arise out of or is based upon (i) any untrue statement or alleged untrue
statement of any material fact by any Credit Party in any document or schedule
executed or filed with any Governmental Authority by or on behalf of any Credit
Party; (ii) any omission or alleged omission to state any material fact required
to be stated in such document or schedule, or necessary to make the statements

                                       99

(iii) any acts, practices or omissions or alleged acts, practices or omissions
of any Credit Party or its agents relating to the use of the proceeds of any or
all borrowings made by the Borrower alleged to be in violation of Section 2.17,
or in violation of any federal securities law or of any other statute,
regulation or other law of any jurisdiction applicable thereto; or (iv) any
acquisition or proposed acquisition by any Credit Party of all or a portion of
the Stock, or all or a portion of the assets, of any Person whether such
Indemnified Person is a party thereto, provided that the Borrower shall have no
obligation under this Section to an Indemnified Person with respect to any of
the foregoing to the extent any such loss, cost, liability, damage or expense
resulted from or arose out of the gross negligence or wilful misconduct of such
Indemnified Person or arose from claims between one such Indemnified Person and
another such Indemnified Person. The indemnity set forth herein shall be in
addition to any other obligations or liabilities of the Borrower to each
Indemnified Person under the Loan Documents or at common law or otherwise, and
shall survive any termination of the Loan Documents, the expiration of the
Commitments and the payment of all indebtedness of the Borrower under the Loan
Documents.

  11.12.  GOVERNING LAW
          -------------

          THE LOAN DOCUMENTS AND THE RIGHTS AND OBLIGATIONS OF THE PARTIES
THEREUNDER SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE

  11.14.  Severability
          ------------

          Every provision of the Loan Documents is intended to be severable, and
if any term or provision thereof shall be invalid, illegal or unenforceable for
any reason, the validity, legality and enforceability of the remaining
provisions thereof shall not be affected or impaired thereby, and any
invalidity, illegality or unenforceability in any jurisdiction shall not affect
the validity, legality or enforceability of any such term or provision in any
other jurisdiction.

  11.15.  Integration
          -----------

          All exhibits to a Loan Document shall be deemed to be a part thereof.
Except for agreements between the Administrative Agent and the Borrower with
respect to certain fees, the Loan Documents embody the entire agreement and
understanding among the Credit Parties, the Administrative Agent and the Lenders
with respect to the subject matter thereof and supersede all prior agreements
and understandings among the Credit Parties, the Administrative Agent and the
Lenders with respect to the subject matter thereof.

                                      100

 
  11.16.  Consent to Jurisdiction
          -----------------------

          Each Credit Party hereby irrevocably submits to the jurisdiction of
any New York State or Federal court sitting in the City of New York over any
suit, action or proceeding arising out of or relating to the Loan Documents.
Each Credit Party hereby irrevocably waives, to the fullest extent permitted or
not prohibited by law, any objection that it may now or hereafter have to the
laying of the venue of any such suit, action or proceeding brought in such a
court and any claim that any such suit, action or proceeding brought in such a
court has been brought in an inconvenient forum.  Each Credit Party hereby
agrees that a final judgment in any such suit, action or proceeding brought in
such a court, after all appropriate appeals, shall be conclusive and binding
upon it.

  11.17.  Service of Process
          ------------------

          Each Credit Party hereby agrees that service of process in any such
suit, action or proceeding brought in the State of New York may be made upon CT
Corporation at its offices at 1633 Broadway, New York, New York 10019 (or any
other location in New York City) (the "Process Administrative Agent") and each
                                       ----------------------------           
Credit Party hereby irrevocably appoints the Process Administrative Agent its
authorized agent to accept such service of process, and agrees that the failure
of the Process Administrative Agent to give any notice of any such service shall
not impair or affect the validity of such service or of any judgment rendered in
any action or proceeding based thereon.  Each Credit Party hereby further
irrevocably consents to the service of process in any suit, action or proceeding
by sending the same by first class mail, return receipt requested or by
overnight courier service, to the address of such Credit Party set forth in or
referred to in Section 11.2 or in the applicable Loan Document executed by such
Credit Party.  Each Credit Party hereby agrees that any such service (i) shall
be deemed in every respect effective service of process upon it in any such
suit, action, or proceeding, and (ii) shall to the fullest extent enforceable by
law, be taken and held to be valid personal service upon and personal delivery
to it.

  11.18.  No Limitation on Service or Suit
          --------------------------------

          Nothing in the Loan Documents or any modification, waiver, consent or
amendment thereto shall affect the right of the Administrative Agent, the Letter
of Credit Issuer or any Lender to serve process in any manner permitted by law
or limit the right of the Administrative Agent, the Letter of Credit Issuer  or
any Lender to bring proceedings against any Credit Party in the courts of any
jurisdiction or jurisdictions in which such Credit Party may be served.

  11.19.  Judgment Currency
          -----------------

payments in the applicable Currency (the "Obligation Currency") shall not be

expressed in or converted into any currency other than the Obligation Currency,
except to the extent that, on the Business Day immediately following the date of
such tender or recovery, the Administrative Agent, the Letter of Credit Issuer,
the Swing Line Lender or the applicable Lender, as the case may be, may, in
accordance with normal banking procedures, purchase the Obligation Currency with
such other currency.  If for the purpose of 

                                      101

 
obtaining or enforcing judgment against any Credit Party in any court or in any
jurisdiction, it becomes necessary to convert into any currency other than the
Obligation Currency (such other currency being hereinafter referred to as the
"Judgment Currency") an amount due in the Obligation Currency, the conversion
 -----------------
shall be made at the rate of exchange at which, in accordance with normal
banking procedures in the relevant jurisdiction, the Obligation Currency could
be purchased with the Judgment Currency as of the day immediately preceding the
day on which the judgment is given.

          (b) If the amount of Obligation Currency purchased pursuant to the
last sentence of subsection (a) above is less than the sum originally due in the
Obligation Currency, the applicable Credit Party covenants and agrees to
indemnify the applicable recipient against such loss, and if the Obligation
Currency so purchased exceeds the sum originally due to such recipient, such
recipient agrees to remit to the applicable Credit Party such excess.

AGENT, THE CO-ARRANGERS, THE LENDERS, THE LETTER OF CREDIT ISSUER AND EACH
CREDIT PARTY EACH HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY
RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION ARISING OUT

LENDERS, OR COUNSEL TO THE ADMINISTRATIVE AGENT, THE DOCUMENTATION AGENT, THE

SYNDICATION AGENT, THE CO-ARRANGERS, THE LETTER OF CREDIT ISSUER AND THE LENDERS
HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, INTER ALIA, THE PROVISIONS OF

THIS SECTION.

  11.21.  International Banking Facilities

          (a) The Borrower acknowledges that some or all of the Lenders may, in
connection with the Loan Documents, utilize an International banking facility
(as defined in Regulation D of the Board of Governors of the Federal Reserve
System).

          (b) The Borrower (i) understands that it is the policy of the Board of
Governors of the Federal Reserve System that deposits received by International
banking 

                                      102

 
facilities may be used only to support the non-U.S. operations of a depositor
(or its foreign affiliates) located outside the United States and that
extensions of credit by International banking facilities may be used only to
finance the non-U.S. operations of a customer (or its foreign affiliates)
located outside the United States, and (ii) acknowledges that the proceeds of
its borrowings hereunder from an International banking facility will be used
solely to finance its operations outside the United States, or those of its
foreign affiliates.

  11.22.  Designation as Designated Senior Indebtedness
          ---------------------------------------------

          This Agreement, the Subsidiary Guaranty, and all Loans and all other
monetary obligations hereunder and thereunder, are hereby expressly designated
as "Designated Senior Indebtedness", as that term is defined in the RTC
Convertible Subordinated Indenture and in the RTC Convertible Subordinated
Guaranty.

  11.23.  Year 2000
          ---------

          The Borrower and its Subsidiaries have reviewed the areas within their
business and operations which could be adversely affected by, and have developed
or are developing a program to address on a timely basis, the "Year 2000
Problem" (that is, the risk that computer applications used by the Borrower and
its Subsidiaries may be unable to recognize and perform properly date-sensitive
functions involving certain dates prior to and any date after December 31,
1999).  Based on such review and program, the Borrower reasonably believe that
the "Year 2000 Problem" will not have a material adverse effect on the financial
condition, operations, business, prospects or Property of the Borrower and its
Subsidiaries taken as a whole since December 31, 1997.
