          The Company agrees to indemnify the Remarketing Agent and the Issuer
for and to hold each harmless against all liabilities, claims, costs and

proceeding brought in connection with the exercise or performance of any of its
powers or duties under the Bonds, the Indenture, the Installment Sale Agreement,
the Bond Purchase Agreement, the Reimbursement Agreement or the Letter of
Credit; except to the extent that any such claim, liability, cost or expense
arises in connection with (i) in respect of the Remarketing Agent, the failure
by the Remarketing Agent to deliver any amended or supplemented Offering
Circular or amendment or supplement to the Offering Circular, to any purchaser

Circular or amendment or supplement to the Offering Circular (in accordance with
Section 3.01 hereof), as the case may be, to the Remarketing Agent for use in

upon receipt of that notice, shall have the right, or, if requested by either
the Remarketing Agent or the Issuer, the obligation to assume the defense of the
claim, action or proceeding at the Company's expense. Such notice shall be given
in sufficient time to allow the Company to defend or participate in such claim,
action or proceeding; provided, that failure of the Remarketing Agent or the

The Company shall not be liable for any settlement made without its consent,
which consent shall not be unreasonably withheld.

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

     The Remarketing Agent may suspend its remarketing efforts immediately upon
the occurrence of any of the following events, but only after notice (a
"Discretionary Suspension Notice") to the Issuer, the Company, the Trustee, and
the Credit Facility Issuer, which suspension will continue only so long as the
event continues to exist if, in the Remarketing Agent's reasonable judgment, the
continuance of the event has a material adverse effect on its ability to

          behalf of, the United States Securities and Exchange Commission or
          other governmental agency having jurisdiction of the subject matter,
          in any such case to the effect that, the offering or sale of
          obligations of the general character of the Bonds, or the remarketing
          of the Bonds, as contemplated hereby, is or would be in violation of
          any provision of the Securities Act of 1933, as amended (the
          "Securities Act") and as then in effect, or the Securities Exchange
          Act of 1934, as amended (the "Exchange Act") and as then in effect, or

          general character of the Bonds, or the Bonds, as contemplated hereby;

               (e)  any event shall occur or information shall become known,
          which, in the Remarketing Agent's reasonable judgment, makes untrue,
          incorrect or misleading in any material respect any statement or
          information contained in the then most current Offering Circular
          provided to the Remarketing Agent in connection with the performance

          incorrect or misleading statement of a material fact or to omit to
          state a material fact required to be stated therein or necessary to
          make the statements made therein, in light of the circumstances under
          which they were made, not misleading;

               (f)  any governmental authority shall impose, as to the Bonds, or
          obligations of the general character of the Bonds, any material
          restrictions not now in force, or increase materially those now in
          force;

               (g)  any of the material representations and warranties of the
          Company made hereunder shall not have been true and correct on the
          date made; or
