          Section 3.01. Increased Costs.
                        --------------- 

          (a) If, after the date of this Agreement, (i) the introduction of, or
any change in, any applicable law, rule or regulation or in the interpretation
or administration thereof by any Governmental Authority or (ii) compliance by
the Bank with any request, guideline, policy or directive of any Governmental
Authority issued after the date of this Agreement (whether or not having the
force of law) shall:

                                       7
<PAGE>
 
               (A) subject the Bank to any tax, duty or other charge or shall
     change the basis of taxation of payments to the Bank of any amount due
     under this Agreement or the Swingline Note (except for changes in the tax
     on the overall net income of the Bank imposed by the jurisdiction of its
     incorporation or the jurisdiction in which its Lending Office is located);

               (B) impose, modify or deem applicable any reserve, special
     deposit or similar requirement against assets or liabilities of, deposits
     with or for the account of, or commitments issued by, the Bank (including,
     without limitation, any such requirement imposed by the Board of Governors
     of the Federal Reserve System); or

               (C) impose on the Bank or the money markets any other condition
     affecting its Commitment, any Loan, any Letter of Credit or the Swingline
     Note;

and the result of any of the foregoing is to increase the cost to the Bank of
making or maintaining its Commitment, any 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 Agreement or under the Swingline Note,
then the Company shall from time to time pay to the Bank within ten Business
Days of its demand therefor such additional amount or amounts as will compensate
it for such increased cost or reduction.

          (b) If the Bank shall have determined that, after the date of this
Agreement, the adoption of any applicable law, rule or regulation regarding
capital adequacy, or any change therein, or any change in the interpretation or
administration thereof by any Governmental Authority, or compliance by the Bank
(or, without duplication, the bank holding company of which the Bank is a
subsidiary) with any request, guideline, policy or directive regarding capital
adequacy (whether or not having the force of law) of any such authority, has or
would have the effect of reducing the rate of return on the Bank's or its bank
holding company's capital as a consequence of any Loans, any Letters of Credit
or its obligations hereunder to a level below that which the Bank or its bank
holding company could have achieved but for such adoption, change or compliance
(taking into consideration the Bank's or the bank holding company's policies
with respect to capital adequacy), then the Company shall from time to time pay
to the Bank within ten Business Days of its demand therefor such additional
amount or amounts as will compensate the Bank or its bank holding company for
such reduction.

          (c) The Bank will promptly give the Company notice of the occurrence
of any event of which it has knowledge which will entitle it to compensation
pursuant to this Section 3.01, and will use reasonable efforts to mitigate the
effect of any such event if, in the sole opinion of the Bank, such efforts will
avoid the need

                                       8
<PAGE>
 
for, or reduce the amount of, such compensation and will not be otherwise
disadvantageous to it or contrary to its internal policies, provided that the
                                                            --------         
failure of the Bank so to notify the Company will not discharge the Company of
its obligations under this Section 3.01.  The Bank shall furnish the Company
with a certificate setting forth the basis for determining any additional amount
or amounts to be paid to it hereunder, and such certificate shall be conclusive,
absent manifest error, as to the contents thereof.

          Section 3.02. Illegality.  If, after the date of this Agreement, the
                        ----------                                            
introduction of, or any change in, any applicable law, rule or regulation or in
the interpretation or administration thereof by any Governmental Authority shall
make it unlawful for the Bank to make or maintain any Loan, then the Bank shall
give notice thereof to the Company and commence good faith negotiations with the
Company to determine a substitute basis for determining a rate of interest
payable to the Bank which would cure such illegality hereunder.  If within 30
days of such notice to the Company, the Company and the Bank shall not have
agreed in writing to such a substitute basis, the Bank may declare such Loan to
be due and payable and the Company shall prepay such Loan in full on the last
day of the Interest Period applicable thereto unless such Loan is required by
law to be sooner repaid, in which case the Company shall repay such Loan on such
earlier date, together with accrued interest thereon and any additional amount
owing under Section 2.06 hereof.  The Bank will promptly notify the Company of
any event of which the Bank has knowledge which will entitle it to the
provisions of this Section 3.02 and will designate a different Lending Office
if, in the sole opinion of the Bank, such designation will avoid the need for
such prepayment and will not be otherwise disadvantageous to it or contrary to
its internal policies.

          Section 3.03. Taxes.
                        ----- 

          (a) Each payment by the Company to the Bank under this Agreement or
any of the Related Documents shall be made free and clear of and without
deduction for any Taxes, other than any Taxes imposed on the overall net income
of the Bank by the jurisdiction of its incorporation or by the jurisdiction in
which its Lending Office is located (all such non-excluded Taxes being
hereinafter referred to as "Covered Taxes").  If the Company shall be required
                            -------------                                     
by law to deduct any Covered Taxes from or in respect of any such payment, then
(i) the sum payable shall be increased as may be necessary so that after making
all required deductions (including deductions applicable to additional sums
payable under this Section) the Bank receives an amount equal to the sum it
would have received had no such deductions been made, (ii) the Company shall
make such deductions and (iii) the Company shall pay on a timely basis the full
amount deducted to the relevant taxation authority or other authority in
accordance with applicable law.

                                       9
<PAGE>
 
          (b) The Company will indemnify the Bank for the full amount of Covered
Taxes required to be paid by, or imposed, levied or assessed against the Bank.
In addition, the Company shall pay to the Bank such amounts as may be necessary
to hold the Bank harmless on an after-tax basis from any Taxes (including
without limitation, income or franchise taxes) imposed by any jurisdiction as a
result of the receipt or accrual by the Bank of any payment under this Section
3.03 (including any payment under this sentence).  Any indemnification pursuant
to this Section 3.03(b) shall be made within 30 days from the date the Bank
makes written demand therefor.  A certificate setting forth any amount payable
to the Bank under this Section 3.03 and the basis therefor submitted by the Bank
to the Company shall, absent manifest error, be conclusive and binding.

          (c) Within 60 days after the date of any payment of Covered Taxes made
under this Section 3.03 or the withholding of any Taxes excluded from
indemnification under subsection (a) the Company will furnish to the Bank the
original or a certified copy of a receipt, accompanied by a certified English
translation if the receipt is not in English, evidencing payment thereof, a
statement signed by an officer responsible for the Company's financial or
accounting records setting forth the amount and identity of such Taxes
(specifying the particular provisions of law requiring such withholding), and
all additional information and documents that the Bank shall reasonably and in
writing request to establish that full and timely payment of such Covered Taxes
or other Taxes has been made.  The Company will promptly notify the Bank of any
reports or returns that the Bank is required to file with respect to Covered
Taxes.

          (d) Without prejudice to the survival of any other agreement of the
Company hereunder, the agreements and obligations of the Company contained in
this Section 3.03 shall survive the prepayment or payment in full or in part of
the Loans and the interest thereon and the termination of this Agreement or any
Related Document.
