         SECTION 2. APPOINTMENT AND OBLIGATIONS OF REMARKETING AGENT. The
Company hereby appoints [Merrill Lynch] and [Merrill Lynch] hereby accepts such
appointment, (i) as the Reset Agent to determine in consultation with the
Company, in the manner provided for herein and in the Indenture (as in effect on

                                       2
<PAGE>

Remarketing Agreement (the "Supplemental Remarketing Agreement") with the
Company and the Purchase Contract Agent, which shall either be (i) substantially
in the form attached hereto as Exhibit A (with such changes as the Company and
the Remarketing Agent may agree upon, it being understood that changes may be
necessary in the representations, warranties, covenants and other provisions of
the Supplemental Remarketing Agreement due to changes in law or facts and
circumstances or in the event that Merrill Lynch is not the sole remarketing
agent, and with such further changes therein as the Remarketing Agent may
reasonably request, or (ii) in such other form as the Remarketing Agent may
reasonably request, subject to the approval of the Company (such approval not to
be unreasonably withheld). Anything herein to the contrary notwithstanding,
Merrill Lynch shall not be obligated to act as Remarketing Agent or Reset Agent
hereunder unless the Supplemental Remarketing Agreement is in form and substance
reasonably satisfactory to Merrill Lynch. The Company agrees that Merrill Lynch
shall have the right, on 15 Business Days notice to the Company, to appoint one
or more additional remarketing agents so long as any such additional remarketing
agents shall be reasonably acceptable to the Company. Upon any such appointment,
the parties shall enter into an appropriate amendment to this Agreement to
reflect the addition of any such remarketing agent. (b) Pursuant to the
Supplemental Remarketing Agreement, the Remarketing Agent, either as sole
remarketing agent or as representative of a group of remarketing agents
appointed as aforesaid, will agree, subject to the terms and conditions set
forth herein and therein, to use its reasonable efforts to (i) remarket, on the
Initial Remarketing Date, the Notes that the Trustee (as such term is defined in

or otherwise are to be included in, the Initial Remarketing, at a price per Note
such that the aggregate price for the Applicable Principal Amount of the Notes

event of a Failed Initial Remarketing, remarket, on the third Business Day
immediately preceding the Purchase Contract Settlement Date, the Notes that the
Trustee shall have notified the Remarketing Agent have been tendered for, or
otherwise are to be included in, the Secondary Remarketing, at a price of
approximately 100.5% of the aggregate principal amount of such Notes.
Notwithstanding the preceding sentence, the Remarketing Agent shall not remarket
any Notes for a price less than the price necessary for the Applicable Principal
Amount of the Notes to have an aggregate price equal to 100% of the Treasury
Portfolio Purchase Price (the "Minimum Initial Remarketing Price"), in the case
of the Initial Remarketing, or the aggregate principal amount of such Notes, in
the case of the Secondary Remarketing. After deducting the fee specified in
Section 3 below, the proceeds of such Initial Remarketing or Secondary
Remarketing, as the case may be, shall be paid to the Collateral Agent in
accordance with Section 4.6 or 6.3 of the Pledge Agreement and Section 5.3 or
5.4 of the Purchase Contract Agreement (each of which Sections are incorporated
herein by reference). The right of each holder of Notes or Income PRIDES to have
Notes tendered for the Initial Remarketing or the Secondary Remarketing, as the
case may be, shall be limited to the extent that (i) the Remarketing Agent
conducts an Initial Remarketing and, in the event of a Failed Initial
Remarketing, a Secondary Remarketing pursuant to the terms of this Agreement,
(ii) Notes tendered have not been called for redemption, (iii) the Remarketing
Agent is able to find a purchaser or purchasers for tendered Notes at a price of
not less than the Minimum Initial Remarketing Price, in the case of the Initial
Remarketing, and 100% of the principal amount thereof, in the case of the
Secondary Remarketing and (iv) such purchaser or purchasers deliver the purchase
price therefor to the Remarketing Agent as and when required. (c) It is
understood and agreed that neither the Remarketing Agent nor the Reset Agent
shall have any obligation

Remarketing or otherwise, and shall in no way be obligated to provide funds to
make payment upon tender of Notes for remarketing or to otherwise expend or risk
their own funds or incur or be exposed to financial liability in the performance
of their respective duties under this Agreement or the Supplemental Remarketing
Agreement, and, without limitation of the foregoing, the Remarketing Agent shall
not be deemed an underwriter of the remarketed Notes. The Company shall not be
obligated in any case to provide funds to make payment upon tender of Notes for
remarketing.

         SECTION 3. FEES. In the event of a Successful Initial Remarketing, the
Remarketing Agent shall retain as a remarketing fee (the "Remarketing Fee") an
amount not exceeding 25 basis points (0.25%) of the Minimum Initial Remarketing
Price from any amount received in connection with such Initial Remarketing in
excess of the Minimum Initial Remarketing Price. In the event of a Successful
Secondary Remarketing, the Remarketing Agent shall retain as the Remarketing Fee
an amount not exceeding 25 basis points (0.25%), of the principal amount of the
remarketed Notes from any amount received in connection with such Secondary
Remarketing in excess of the aggregate principal amount of such remarketed
Notes. In addition, the Reset Agent shall, in either case, receive from the
Company a reasonable and customary fee (the "Reset Agent Fee"); provided,
however, that if the Remarketing Agent shall also act as the Reset Agent, then
the Reset Agent shall not be entitled to receive any such Reset Agent Fee.
Payment of such Reset Agent Fee shall be made by the Company on the Initial
Remarketing Date, in the case of a Successful Initial Remarketing, or on the
third Business Day immediately preceding the Purchase Contract Settlement Date,

         SECTION 20. [JUDGEMENT CURRENCY. The Company agrees to indemnify each
of the Remarketing Agent and the Purchase Contract Agent against any loss
incurred by such party as a result of any judgment or order being given or made
for any amount due hereunder and such judgment or order being expressed and paid
in a currency (the "Judgment Currency") other than United States dollars and as
a result of any variation as between (i) the rate of exchange at which the
United States dollar amount is converted into the Judgment Currency for the
purpose of such judgment or order, and (ii) the rate of exchange at which the
such party is able to purchase United States dollars with the amount of the
Judgment Currency actually received by such party. The foregoing indemnity shall
constitute a separate and independent obligation of the Company and shall
continue in full force and effect notwithstanding any such judgment or order as
aforesaid. The term "rate of exchange" shall include any premiums and costs of
exchange payable in connection with the purchase of, or conversion into, the
relevant currency.]
