     inconsistent with 

 
                                      -4-

                           --------------------------

Letter of Credit issued, extended or renewed by the Bank hereunder,

            (a)  except as otherwise expressly provided in (S)2A.2(b) and (c),
     on each date that any draft presented under such Letter of Credit is
     honored by the Bank, or the Bank otherwise makes a payment with respect to
     such draft, (i) the amount paid by the Bank under or with respect to such
     Letter of Credit, and (ii) the amount of any taxes, fees, charges or other
     costs and expenses whatsoever incurred by the Bank in connection with any
     payment made by the Bank under, or with respect to, such Letter of Credit,

            (b)  upon the reduction (but not termination) of the Commitment to
     an amount less than the Maximum Drawing Amount, an amount equal to such
     difference, which amount shall be held by the Bank as cash collateral for
     all Reimbursement Obligations, and

            (c)  upon the termination of the Commitment, or the acceleration of
     the Reimbursement Obligations with respect to all Letters of Credit in
     accordance with (S)9, an amount equal to the then Maximum Drawing Amount on
     all Letters of Credit, which amount shall be held by the Bank as cash
     collateral for all Reimbursement Obligations.

All payments hereunder may be made by the Borrowers with the proceeds of
Revolving Credit Loans, provided that the Borrowers are not then in default
hereunder and the limitation set forth in (S)2A1.1(b) would not thereby be
exceeded.  Each such payment shall be made to the Bank at the Bank's head office
in immediately available funds.  Interest on any and all amounts remaining
unpaid by the Borrowers under this (S)2A.2 at any time from the date such
amounts become due and payable (whether as stated in this (S)2A.2, by
acceleration or otherwise) until payment in full (whether before or after
judgment) shall be payable to the Bank on demand at the rate specified in (S)3.7
for overdue principal on the Revolving Credit Loans.

other demand for payment shall be made under any Letter of Credit, the Bank

demand for payment 

 
                                      -5-

and of the date and time when it expects to pay such draft or honor such demand
for payment. The responsibility of the Bank to the Borrowers shall be only to
determine that the documents (including each draft) delivered under each Letter
of Credit in connection with such presentment shall be in conformity in all
material respects with such Letter of Credit.

     (S)2A.4.  OBLIGATIONS ABSOLUTE.  The Borrowers' obligations under this
               --------------------                                        
(S)2A shall be absolute and unconditional under any and all circumstances and
irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrowers may have or have had against the Bank, or any beneficiary of
a Letter of Credit.  Each Borrower further agrees with the Bank that the Bank
shall not be responsible for, and the Borrowers' Reimbursement Obligations under
(S)2A.2 shall not be affected by, among other things, the validity or
genuineness of documents or of any endorsements thereon as long as such
documents comply on their face with the requirements of the Letter of Credit,
even if such documents should in fact prove to be in any or all respects
invalid, fraudulent or forged, or any dispute between or among either Borrower,
the beneficiary of any Letter of Credit or any financing institution or other
party to which any Letter of Credit may be transferred or any claims or defenses
whatsoever of either Borrower against the beneficiary of any Letter of Credit or
any such transferee except to the extent that any of the foregoing arises out of
the gross negligence or willful misconduct of the Bank.  The Bank shall not be
liable for any error, omission, interruption or delay in transmission, dispatch
or delivery of any message or advice, however transmitted, in connection with
any Letter of Credit except to the extent that any of the foregoing arises out
of the gross negligence or willful misconduct of the Bank.  Each Borrower agrees
that any action taken or omitted by the Bank under or in connection with each
Letter of Credit and the related drafts and documents, if done in good faith,
shall be binding upon such Borrower and shall not result in any liability on the
part of the Bank to such Borrower.

     (S)2A.5.  RELIANCE BY ISSUER.  To the extent not inconsistent with (S)2A.4,
               ------------------                                               
the Bank shall be entitled to rely, and shall be fully protected in relying
upon, any Letter of Credit, draft, writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document believed by it in good faith 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, independent
accountants and other experts selected by the Bank.

of Credit in an amount equal to two percent (2.00%) per annum on the face amount
of such documentary Letter of Credit, plus the Bank's customary issuance,
                                      ----

     thereof (whether or not having the force of law), or (ii) compliance by the
     Bank or its parent holding company with any guideline, request or directive
     (whether or not having the force of law), (A) shall subject the Bank to any
     tax, duty or other charge with respect to any Eurodollar Rate Loan, any
     Letter of Credit or the Revolving Credit Note, or shall change the basis of
     taxation of payments to the Bank of the principal of or interest on,
     Eurodollar Rate Loans or in respect of any other amounts due under this
     Agreement in respect of Eurodollar Rate Loans (other than with respect to
     taxes based upon the Bank's net income), or (B) shall impose, modify or
     deem applicable any reserve, special deposit or similar requirement
     (including, without limitation, any imposed by the Board of Governors of
     the Federal Reserve System, but excluding with respect to any Eurodollar
     Rate Loan any such requirement included in an applicable Eurocurrency
     Reserve Rate) against assets of, deposits with or for the account of, or
     credit extended by, the Bank, or shall impose on the Bank or the London
     interbank market any other condition affecting Eurodollar Rate Loans, any
     Letter of Credit or the Revolving Credit Note, and the result of any of the
     foregoing is to increase the cost to the Bank of making or maintaining any
     Eurodollar Rate Loan or any Letter of Credit, or to reduce the amount of
     any sum received or receivable by the Bank under this Agreement, under any
     Letter of Credit or under the Revolving Credit Note with respect to any
     Revolving Credit Loan, by an amount reasonably deemed by the Bank to be
     material, then, upon demand by the Bank, the Borrowers jointly and
     severally agree to pay to the Bank such additional amount or amounts as
     will compensate the Bank for such increased cost or reduction.  The Bank
     agrees to provide a certificate to the Borrowers as to any such costs, or
     reduction including calculations in reasonable detail.
