     "Regulatory Change" means any change enacted or issued after the date of
     this Agreement of any (or the adoption after the date of this Agreement of
     any new) federal or state law, regulation, interpretation, direction,

                                       4
<PAGE>


     Lender or any corporation controlling such Lender. If such Regulatory
     Change has the effect of reducing the rate of return on such Lender's or
     such corporation's capital as a consequence of the Revolving Loans, the
     Letter of Credit or commitments of such Lender hereunder to a level below
     that which such Lender or such corporation could have achieved but for such
     Regulatory Change (taking into account such Lender's or such corporation's
     policies with respect to capital adequacy) by an amount deemed in good
     faith by such Lender to be material, then from time to time following
     notice by such Lender to the Company of such Regulatory Change, within ten
     days after demand from such Lender, the Company shall pay to such Lender
     such additional amount or amounts as will compensate such Lender or such
     corporation, as the case may be, for such reduction. Such notice (which
     shall include calculations in reasonable detail) shall, in the absence of
     manifest error, be conclusive and binding on the Company.

             2.14 Yield Protection. If any law or any governmental rule,
     regulation, policy, guideline or directive (whether or not having the force
     of law), or any interpretation thereof, or the compliance of any Lender
     therewith,

         (a) subjects any Lender to any tax, duty, charge or withholding on or
from payments due from the Company (excluding federal taxation of the overall
net income of any Lender and any such tax, duty, charge or withholding in effect
as of the date of this Agreement), or changes the basis of taxation of payments
to any Lender in respect of its Revolving Loans, the Letter of Credit or other
amounts due it hereunder (excluding federal taxation of the overall net income
of any Lender);

         (b) imposes or increases or deems applicable any reserve, assessment,
insurance charge, special deposit or similar requirement against assets of,
deposits with or for the account of, or credit extended by, any Lender (other
than reserves and assessments taken into account in determining the interest
rate applicable to LIBOR Rate Loans) with respect to its Revolving Loans or the
Letter of Credit; or

         (c) imposes any other condition the result of which is to increase the
cost to any Lender of making, funding or maintaining the Revolving Loans or the
Letter of Credit or reduces any amount received by any Lender in connection with
the Revolving Loans or the Letter of Credit



                                       5
<PAGE>


or requires any Lender to make any payment calculated by reference to the amount
of Revolving Loans held or interest received by it or by reference to the amount
of such Lender's participation in the Letter of Credit, by an amount deemed
material by such Lender;

then, within 15 days of demand by such Lender, the Company shall pay such Lender
that portion of such increased expense incurred or reduction in an amount
received which such Lender determines is attributable thereto. Such notice
(which shall include calculations in reasonable detail) shall, in the absence of
manifest error, be conclusive and binding on the Company.

     (a) at any time that a Default or Event of Default exists hereunder, or (b)
     if no Default or Event of Default then exists, if such amendment,
     modification, supplementation or revision would (i) alter any of the "money
     terms" under the Indenture, including, the rate of interest payable
     thereunder, the amount of, or schedule for the repayment of the principal
     thereof, or the amount of any fees payable thereunder, (ii) require any

     fees) incurred in connection with any and all claims or proceedings
     (whether brought by a private party or governmental agency) as a result of,
     or arising out of or relating to:

                 (a) bodily injury, property damage, abatement or remediation,
          environmental damage or impairment or any other injury or damage
          resulting from or relating to any hazardous or toxic substance or
          contaminated material (as determined under Environmental Laws) located
          on or migrating into, from or through property previously, now or
          hereafter owned or occupied by the Company, which the Agent or any
          Lender may incur due to the making of the Revolving Loans, the
          exercise of any of its rights under the Security Documents, or
          otherwise;

                 (b) any transaction financed or to be financed, in whole or in
          part, directly or indirectly, with the proceeds of any Revolving Loan;

                 (c) any claim that the offering, issuance, placement or sale of
          Commercial Paper, or any document used in connection therewith,
          resulted in a violation of law, including any federal or state
          securities law;

                 (d) the entering into, performance of and exercise of their
          rights under this Agreement or any other Loan Document by the Agent,
          the Collateral Custodian and the Lenders;

                 (e) the execution and delivery or transfer of, or payment or
          failure to pay under, the Letter of Credit; provided, however, that
          the Company shall not be required to indemnify the Agent or the
          Lenders for any claims, damages, losses, liabilities, costs or
          expenses to the



                                       7
<PAGE>


          extent, but only to the extent, caused by (i) the willful misconduct
          or gross negligence of the Agent in determining whether a draw or
          certificate presented under the Letter of Credit complied with the
          terms of the Letter of Credit or (ii) the Agent's willful failure to
          pay under the Letter of Credit after the presentation to it by the
          Certificate Trustee of a draw and certificate strictly complying with
          the terms and conditions of the Letter of Credit; and

                 (f) the issuance and sale of the Certificates of Participation
          in the trust created under the Indenture, the issuance of the Letter
          of Credit or the consummation of the transactions contemplated by the
          Indenture; provided, however, that the Company shall not be required
          to indemnify the Agent or the Lenders for any claims, damages, losses,
          liabilities, costs or expenses to the extent, but only to the extent,
          caused by (i) any misstatement of a material fact concerning the Agent
          which was made or furnished by the Agent or (ii) any failure by the
          Agent to state a material fact concerning the Agent, in connection
          with the sale of such Certificates of Participation.

                     This indemnity will survive foreclosure of any security
          interest or mortgage or conveyance in lieu of foreclosure and the
          repayment of the Revolving Loans and the discharge and release of the
          Security Documents.

         (l) References in the Loan Documents to "a Letter of Credit," "each
Letter of Credit" and "the Letters of Credit" shall refer to the Letter of
