Section 2. Appointment and Obligations of Remarketing Agent.

         (a) The Company hereby appoints Salomon Smith Barney Inc. and Salomon
Smith Barney Inc. hereby accepts such appointment, (i) as the Remarketing Agent
to determine, in consultation with the Company, in the manner provided for
herein, in the Forward Purchase Contract Agreement and in the Notes, the Reset
Rate that, in the opinion of the Remarketing Agent, will, when applied to the
Notes (assuming, even if not true, that all of the Notes are included in the
remarketing), enable the then current aggregate market value of the Notes to
have a value equal to at least 100.5% of the Remarketing Value or Accelerated
Remarketing Value, as applicable, as of the Remarketing Date, any Accelerated
Remarketing Date or as of any Subsequent Remarketing Date, as the case may be,
provided that the Company, by notice to the Remarketing Agent prior to (A) the
tenth Business Day preceding the Remarketing Date, with respect to any
remarketing to occur on either the Remarketing Date or the two Business Days
immediately following such Remarketing Date, (B) the fifth Business Day
preceding any Accelerated Remarketing Date, with respect to any remarketing to
occur on either such Accelerated Remarketing Date or on the two Business Days
immediately following such Accelerated Remarketing Date, and (C) the thirteenth
Business Day preceding any subsequent Remarketing Period, shall, if applicable,
limit the Reset Rate so that it does not exceed the maximum rate permitted by
applicable law, and (ii) as the exclusive Remarketing Agent (subject to the
right of such Remarketing Agent to appoint additional remarketing agents
hereunder as described below) to remarket the Notes to be included in the
remarketing on the Remarketing Date, any Accelerated Remarketing Date or during
any subsequent Remarketing Period, as the case may be. The Remarketing Agent
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 additional remarketing agent.

         (b) Subject to the terms and conditions set forth herein and in the
Forward Purchase Contract Agreement, the Remarketing Agent shall use its
commercially reasonable best efforts to (i) remarket on the Remarketing Date or
any Accelerated Remarketing Date the Notes that the Forward Purchase Contract
Agent or the Custodial Agent shall have notified the Remarketing Agent are to be
remarketed at a Reset Rate such that the then current aggregate market value of
the Notes is equal to at least 100.5% of the Remarketing Value or the
Accelerated Remarketing Value, as applicable, (ii) in the event the Remarketing
Agent cannot establish such a Reset Rate on the Remarketing Date, attempt to
remarket such Notes on each of the two Business Days immediately following the
Remarketing Date and, if necessary, on each of the three Business Days
immediately preceding the 17th day of each following month until the earlier to
occur of (1) a successful remarketing or (2) the Scheduled Stock Purchase Date,
in each case at a Reset Rate such that the then current aggregate market value
of the Notes is equal to at least 100.5% of the Remarketing Value, (iii) in the
event of an Initial Acceleration Event or Secondary Acceleration Event, to
remarket the Notes on any Accelerated Remarketing

Date or Subsequent Remarketing Date in accordance with Section 5.9 of the
Forward Purchase Contract Agreement and (iv) in the event of a Last Failed
Remarketing or a Last Failed Accelerated Remarketing, promptly return the
Pledged Notes, if any, included in such Last Failed Remarketing or Last Failed
Accelerated Remarketing to the Collateral Agent to be held by the Collateral
Agent in accordance with Section 4.5(b) of the Pledge Agreement (which Section
is incorporated herein by reference) and return any Separate Notes included in
the remarketing to the Custodial Agent in accordance with Section 4.5(d) of the
Pledge Agreement and Section 5.2(e) of the Forward Purchase Contract Agreement
(which Sections are incorporated herein by reference). After deducting the fee
specified in Section 3 below, the proceeds of any such successful remarketing
shall be delivered to the Forward Purchase Contract Agent or the Custodial
Agent, as applicable, in accordance with Section 4.5(a) of the Pledge Agreement
(which Section is incorporated herein by reference) and Sections 5.2(b) and 5.9
of the Forward Purchase Contract Agreement (which Sections are incorporated
herein by reference). The right of each Holder of Upper DECS or Separate Notes
to have Notes included in any remarketing shall be subject to the conditions
that (i) the Remarketing Agent conducts a remarketing on such date pursuant to
the terms of this Agreement, (ii) the Notes included in a remarketing have not
been called for redemption upon the occurrence of a Tax Event, (iii) the
Remarketing Agent is able to find a purchaser or purchasers for the Notes
included in a remarketing at a Reset Rate such that the then current aggregate
market value of the Notes is equal to at least 100.5% of the Remarketing Value
or the Accelerated Remarketing Value, as applicable, 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 the Remarketing Agent shall not
have any obligation whatsoever to purchase any Notes, whether in a remarketing
held on the Remarketing Date or an Accelerated Remarketing Date or on any
Subsequent Remarketing Date 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 its own funds or incur or be exposed to financial
liability in the performance of its duties under this Agreement. The Company
shall not be obligated in any case to provide funds to make payment upon
delivery of Notes for remarketing.

Section 3. Fees.

         In the event of a successful remarketing, the Remarketing Agent shall
retain as a remarketing fee (the "Remarketing Fee") an amount not exceeding 25
basis points (0.25%) of the total proceeds received in connection with the
remarketing. Payment of such Remarketing Fee shall be made by the Company on the
date of any such successful remarketing in immediately available funds or, upon
the instructions of the Remarketing Agent, by certified or official bank check
or checks or by wire transfer.

Section 4. Replacement and Resignation of Remarketing Agent.

         (a) The Company may in its absolute discretion replace Salomon Smith

Business Day immediately prior to an Accelerated Remarketing Date in the case of
a Remarketing to occur on such Accelerated Remarketing Date or either of the two

Period. Any such replacement shall become effective upon the Company's
appointment of a successor to perform the services that would otherwise be
performed hereunder by the Remarketing Agent. Upon providing such notice, the
Company shall use all reasonable efforts to appoint such a successor and to
enter into a remarketing agreement with such successor as soon as reasonably
practicable.

         (b) Salomon Smith Barney Inc. may resign at any time and be discharged
from its duties and obligations hereunder as the Remarketing Agent by giving
notice prior to 3:00 p.m., New York City time on (i) the eleventh Business Day
immediately prior to the Remarketing Date in the case of a remarketing to occur
on the Remarketing Date or any of the two Business Days immediately following

Accelerated Remarketing Date in the case of a remarketing to occur on such
Accelerated Remarketing Date or either of the two Business Days immediately

resignation shall become effective upon the Company's appointment of a successor
to perform the services that would otherwise be performed hereunder by the
Remarketing Agent. Upon receiving notice from the Remarketing Agent that it
wishes to resign hereunder, the Company shall use all reasonable efforts to
appoint such a successor and enter into a remarketing agreement with it as soon
as reasonably practicable.

         (c) The Company shall give the Forward Purchase Contract Agent, the
Collateral Agent, the Custodial Agent and the Trustee prompt written notice of
any replacement of the Remarketing Agent pursuant to this section.

individual or any other capacity, may, to the extent permitted by law, buy,
sell, hold or deal in any of the Notes, Stripped DECS, Upper DECS or any other
securities of the Company. With respect to any Notes, Stripped DECS, Upper DECS
or any other securities of the Company owned by it, the Remarketing Agent may
exercise any vote or join in any action with like effect as if it did not act in
any capacity hereunder. The Remarketing Agent, in its individual capacity,
either as principal or agent, may also engage in or have an interest in any
financial or other transaction with the Company as freely as if it did not act
in any capacity hereunder.

         The Company or its affiliates may, to the extent permitted by law,
purchase any Notes that are remarketed by the Remarketing Agent.

for each of the Remarketing Agent and the Company, by applicable law,
regulations or interpretations in effect at the time of the Remarketing Date or
Subsequent Remarketing Date, as the case may be, the Company (i) shall use its
reasonable efforts (A) to have a registration statement relating to the Notes

prior to the commencement of each subsequent Remarketing Period, if any (or in
each such case, at such earlier date as the Remarketing Agent may reasonably
request), and (ii) if requested by the Remarketing Agent, shall furnish a
current final prospectus or, if applicable, a final prospectus supplement, to be
used by the Remarketing Agent in the remarketing hereunder, by a date that is no

         (b) If in connection with any remarketing, it shall not be possible, in
the view of counsel (which need not be an opinion) for each of the Remarketing
Agent and the Company, under applicable law, regulations or interpretations in
effect as of the Remarketing Date, Accelerated Remarketing Date or subsequent
Remarketing Period, as the case may be, to register the offer and sale by the
Remarketing Agent of the Notes under the Securities Act of 1933 as otherwise
contemplated by this Section 6, the Company (i) shall use its reasonable efforts
to take, or cause to be taken, all action and to do, or cause to be done, all
things necessary, proper and advisable to permit and effectuate the offer and
sale of the Notes in connection with any remarketing hereunder without
registration under the Securities Act of 1933 pursuant to an exemption
therefrom, if available, including the exemption afforded by Rule 144A
promulgated under the Securities Act of 1933 by the Securities and Exchange
Commission, and (ii) if requested by the Remarketing Agent, shall furnish a
current preliminary remarketing memorandum and a current final remarketing

         (c) The Company shall also take all such actions as may (upon advice of
counsel to the Company or the Remarketing Agent) be necessary or desirable under
state securities or blue sky laws in connection with any remarketing.

Income Security Act of 1974, as amended ("ERISA"), each individual retirement
account subject to Section 4975 of the Internal Revenue Code of 1986, as amended
(the "Code"), and each entity whose assets include plan assets under Title I of

Remarketing Agent under this


                                      -7-
<PAGE>


Agreement shall be suspended until such default or event has been cured. The
Company will promptly give the Remarketing Agent notice of all such defaults and
events of which the Company is aware.

Section 8. Termination of Remarketing Agreement.

         This Agreement shall terminate as to any Remarketing Agent which is
replaced on the effective date of its replacement pursuant to Section 4(a)
hereof or pursuant to Section 4(b) hereof. Notwithstanding the foregoing, the
obligations set forth in Section 3 hereof shall survive and remain in full force
and effect until all amounts payable under Section 3 shall have been paid in
full; provided, however, that if any Remarketing Agent resigns, then, with
respect to such Remarketing Agent, the obligations set forth in Section 3 hereof
shall not survive the termination of this Agreement and no fee shall be payable
to such Remarketing Agent in such capacity. In addition, each current and former
Remarketing Agent shall be entitled to the rights and benefits under Sections 9,
10 and 12(b) of this Agreement notwithstanding the replacement or resignation of
such Remarketing Agent or termination of this Agreement.

Section 9. Remarketing Agent's Performance; Duty of Care.

         The duties and obligations of the Remarketing Agent shall be determined
solely by the express provisions hereof. No implied covenants or obligations of
or against the Remarketing Agent shall be read into this Agreement. In the
absence of a final judicial determination of willful misconduct, bad faith or
gross negligence on the part of the Remarketing Agent, the Remarketing Agent may
conclusively rely upon any document furnished to it which purports to conform to
the requirements hereunder as to the truth of the statements expressed therein.
The Remarketing Agent shall be protected in acting upon any document or
communication reasonably believed by it to be signed, presented or made by the
proper party or parties. The Remarketing Agent shall not have any obligation to
determine whether there is any limitation under applicable law on the Reset Rate
on the Notes or, if there is any such limitation, the maximum permissible Reset
Rate on the Notes, and it shall rely solely upon timely written notice from the
Company pursuant to Section 2(a) hereof as to whether or not there is any such
limitation and, if so, the maximum permissible Reset Rate. The Remarketing Agent
shall not incur any liability under this Agreement to any beneficial owner or
holder of Notes, or other securities, either in its individual capacity or as
Remarketing Agent, as the case may be, for any action or failure to act in
connection with the remarketing of the Notes or otherwise in connection with the
transactions contemplated by this Agreement, except to the extent that such
liability has, by final judicial determination, resulted from the willful
misconduct, bad faith or gross negligence of the Remarketing Agent or from its
failure to fulfill its express obligations hereunder. The provisions of this
Section 9 shall survive any termination of this Agreement and shall also
continue to apply to every Remarketing Agent notwithstanding its resignation or
removal. The Remarketing Agent will act as the agent of the Holders.

its part, arising out of or in connection with the acceptance or administration
of its powers and duties under this Agreement, including the reasonable
out-of-pocket costs and expenses (including reasonable fees and expenses of
counsel) of defending itself against any claim or liability in connection with
the exercise or performance of such powers and duties or collecting such

reasonably satisfactory to the indemnified party, and no such claim shall be
settled without the written consent of the Company, which consent shall not be
unreasonably withheld.

Stock Purchase Date. Anything herein to the contrary notwithstanding, the
provisions of the second and third sentences of Section 8 hereof and the
provisions of Sections 3, 9, 10 and 12(b) hereof shall survive any termination
of this Agreement and remain in full force and effect.

         (b) All representations and warranties included in this Agreement or
contained in certificates of officers of the Company submitted pursuant hereto
shall remain operative and in full force and effect, regardless of any
investigation made by or on behalf of the Remarketing Agent or any of its
controlling persons, or by or on behalf of the Company or the Forward Purchase
Contract Agent, and shall survive the termination of this Agreement.

Section 13. Successors and Assigns.

         The rights and obligations of the Company and the Forward Purchase
Contract Agent (both in its capacity as Forward Purchase Contract Agent and as
attorney-in-fact for the Holders) hereunder may not be assigned or delegated to
any other person (except pursuant to sections 7.9, 7.10 and 7.11 and Article IX
