     (e)  In the event of a Failed Remarketing, or if no Senior Notes are
included in Corporate Units and none of the Holders of the Separate Senior Notes

interest rate on the Senior Notes will not be reset and will continue to be the
Coupon Rate set forth in the Indenture.

     (f)  If, by 4:00 p.m., New York City time, on the applicable Remarketing
Date, the Remarketing Agent is unable to remarket all of the Remarketed Senior
Notes at the Remarketing Price or the Final Remarketing Price, as the case may
be, pursuant to the terms and conditions hereof, a Failed Remarketing shall be
deemed to have occurred, and the Remarketing Agent shall advise by telephone the

shall advise, by telephone:

          (i)    the Depositary, the Purchase Contract Agent and the Company of
     the Reset Rate determined by the Remarketing Agent in such Remarketing and
     the number of Remarketed Senior Notes sold in such Remarketing;

          (ii)   each purchaser (or the Depositary Participant thereof) of
     Remarketed Senior Notes of the Reset Rate and the number of Remarketed
     Senior Notes such purchaser is to purchase; and

          (iii)  each such purchaser to give instructions to its Depositary
     Participant to pay the purchase price on the third business day immediately
     following the date of such Successful Remarketing in same day funds against
     delivery of the Remarketed Senior Notes purchased through the facilities of
     the Depositary.

     The Remarketing Agent shall also, if required by the Securities Act or the
rules and regulations promulgated thereunder, deliver to each purchaser a
Prospectus in connection with the Remarketing.

     (h)  After deducting any fees specified in Section 4 below, the proceeds
from a Successful Remarketing (i) with respect to the Senior Notes that are

Agent for payment to the Holders of such Separate Senior Notes in accordance
with Section 5.02 of the Purchase Contract Agreement and Section 6.03 of the
Pledge Agreement.

     (i)  The right of each holder of Separate Senior Notes or Corporate Units
to have Remarketed Senior Notes remarketed and sold on any Remarketing Date
shall be subject to the conditions that (i) the Remarketing Agent conducts an
Initial Remarketing and, in the event of a Failed Initial Remarketing, a Final
Remarketing, each pursuant to the terms of this Agreement, (ii) a Special Event
Redemption has not occurred prior to such Remarketing Date, (iii) the
Remarketing Agent is able to find a purchaser or purchasers for Remarketed
Senior Notes at the Remarketing Price or the Final Remarketing Price, as the
case may be, based on the Reset Rate, and (iv) such purchaser or purchasers
deliver the purchase price therefor to the Remarketing Agent as and when
required.

     (j)  It is understood and agreed that the Remarketing Agent shall not have
any obligation whatsoever to purchase any Remarketed Senior Notes, whether in
the Remarketing or otherwise, and shall in no way be obligated to provide funds
to make payment upon tender of Remarketed Senior Notes for Remarketing or to
otherwise expend or risk its own funds or incur or to be exposed to financial
liability in the performance of its duties under this Agreement, and without
limitation of the foregoing, the Remarketing Agent shall not be deemed an
underwriter of the Remarketed Senior Notes. Neither the Company nor the
Remarketing Agent shall be obligated in any case to provide funds to make
payment upon tender of the Remarketed Senior Notes for Remarketing.

opinion furnished pursuant to Section 5(e) of the Underwriting Agreement,
adapted as necessary to relate to the securities being remarketed hereunder and
to the Remarketing Materials, if any, or to any changed circumstances or events
occurring subsequent to the date of this Agreement, such adaptations being
reasonably acceptable to counsel to the Remarketing Agent.

     (g)  Counsel for the Remarketing Agent, shall have furnished to the
Remarketing Agent its opinion, addressed to the Remarketing Agent and dated the
applicable Remarketing Date, in form and substance satisfactory to the
Remarketing Agent.

     (h)  Subsequent to the execution and delivery of this Agreement and prior
to the applicable Remarketing Date, there shall not have occurred any
downgrading, nor shall any notice have been given of any intended or potential
downgrading or of any review for a possible change that does not indicate an
improvement, in the rating accorded any of the Company's securities by any
"nationally recognized statistical rating organization," as such term is defined
for purposes of Rule 436(g)(2) under the Securities Act.

     (i)  The Senior Notes shall not have been called for redemption following
the occurrence of a Special Event. If any condition specified in this Section 6
is not satisfied when and as required to be satisfied, this Agreement may be

prior to the applicable Remarketing Date, which termination shall be without
liability on the part of any party to any other party, except that Sections, 5,

     SECTION 7. INDEMNIFICATION.

     (a)  The Company will indemnify and hold harmless the Remarketing Agent,
its partners, directors and officers, each person, if any, who controls the
Remarketing Agent within the meaning of Section 15 of the Securities Act and
each affiliate of the Remarketing Agent within the meaning of Rule 405 under the
Securities Act as follows:

          (i)    against any and all loss, liability, claim and damage
     (including, without limitation, any legal or other expenses reasonably
     incurred in investigating or defending any such liability or claim)
     whatsoever, as incurred, arising out of any untrue statement or alleged
     untrue statement of a material fact contained in the Registration Statement
     (or any amendment thereto), including the information deemed to be part of
     the Registration Statement pursuant to Rule 430A or Rule 434 under the Act
     (the "Rule 430A/434 Information"), if applicable, or the omission or
     alleged omission therefrom of a material fact required to be stated therein
     or necessary to make the statements therein not misleading or arising out
     of any untrue statement or alleged untrue statement of a material fact
     included in any Preliminary Prospectus or the Prospectus (or any amendment
     or supplement thereto), or the omission or alleged omission therefrom of a
     material fact necessary in order to make the statements therein, in the
     light of the circumstances under which they were made, not misleading;

          (ii)   against any and all loss, liability, claim, damage and expense
     whatsoever, as incurred, to the extent of the aggregate amount paid in
     settlement of any litigation, or any investigation or proceeding by any
     governmental agency or body, commenced or threatened, or of any claim
     whatsoever based upon any such untrue statement or omission, or any such
     alleged untrue statement or omission; provided that (subject to Section
     7(d) below) any such settlement is effected with the written consent of the
     Company; and

          (iii)  against any and all expense whatsoever, as incurred (including
     the fees and disbursement of counsel), reasonably incurred in
     investigating, preparing or defending against any litigation, or any
     investigation or proceeding by any governmental agency or body, commenced
     or threatened, or any claim whatsoever based upon any such true statement
     or omission, or any such alleged untrue statement or omission, to the
     extent that any such expense is not paid under (i) or (ii) above;

provided, however, that the indemnity set forth above shall not apply to any
loss, liability, claim, damage or expense to the extent arising out of any
untrue statement or omission or alleged untrue statement or omission made in
reliance upon and in conformity with written information furnished to the
Company by the Remarketing Agent expressly for use in the Registration Statement
(or any amendment thereto), including the Rule 430A/434 Information, if
applicable, or any Preliminary Prospectus or the Prospectus (or any amendment or
supplement thereto); and provided, further, that the foregoing indemnity with
respect to any Preliminary Prospectus shall not inure to the benefit of the
Remarketing Agent from whom the person asserting any such losses, claims,
damages, or liabilities purchased Securities, or any person controlling the
Remarketing Agent, if a copy of the Prospectus (as then amended or supplemented
if the Company shall have furnished any amendments or supplements thereto) was
not sent or given by

                                       12

<PAGE>

or on behalf of the Remarketing Agent to such person, if required by law so to
have been delivered, at or prior to the written confirmation of the sale of the
Remarketed Senior Notes to such person, and if the Prospectus (as so amended or
supplemented) would have cured the defect giving rise to such losses, claims,
damages or liabilities, unless such failure is the result of noncompliance by
the Company with Section 5(a)(vi) hereof.

     (b)  The Remarketing Agent will indemnify and hold harmless the Company,
its directors, each of its officers who signed the Registration Statement, and
each person, if any, who controls the Company within the meaning of Section 15
of the Securities Act or Section 20 of the Exchange Act against any and all
loss, liability, claim, damage and expense described in the indemnity contained
in subsection (a) of this Section, as incurred, but only with respect to untrue
statements or omissions, or alleged untrue statements or omissions, made in the
Registration Statement (or any amendment thereto), including the Rule 430A/434
Information, if applicable, or any Preliminary Prospectus or the Prospectus (or
any amendment or supplement thereto) in reliance upon and in conformity with
written information furnished to the Company by the Remarketing Agent expressly
for use in the Registration Statement (or any amendment thereto) or such
Preliminary Prospectus or the Prospectus (or any amendment or supplement
thereto).

     (c)  Each indemnified party shall give written notice as promptly as
reasonably practicable to each indemnifying party of any action commenced
against it in respect of which indemnity may be sought hereunder, but failure to
so notify an indemnifying party shall not relieve such indemnifying party from
any liability hereunder to the extent it is not materially prejudiced as a
result thereof and in any event shall not relieve it from any liability which it
may have otherwise than on account of this indemnity agreement. The indemnifying
party, upon request of the indemnified party, shall retain counsel reasonably
satisfactory to the indemnified party to represent the indemnified party and any
others the indemnifying party may designate in such proceeding and shall pay the
fees and disbursements of such counsel related to such proceeding. In any such
proceeding, any indemnified party shall have the right to retain its own
counsel, but the fees and expenses of such counsel related to such proceeding
shall be at the expense of such indemnified party unless (i) the indemnifying
party and the indemnified party shall have mutually agreed to the retention of
such counsel or (ii) the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified party
and the representation of both parties by the same counsel would be
inappropriate due to actual or potential differing interests between them. In no
event shall the indemnifying parties be liable for fees and expenses of more
than one counsel (in addition to any local counsel) separate from their own
counsel for all indemnified parties in connection with any one action or
separate but similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances. No indemnifying party shall,
without the prior written consent of the indemnified parties, settle or
compromise or consent to the entry of any judgment with respect to any
litigation, or any investigation or proceeding by any governmental agency or
body, commenced or threatened, or any claim whatsoever in respect of which
indemnification or contribution could be sought under this Section 7 or Section
8 hereof (whether or not the indemnified parties are actual or potential parties
thereto), unless such settlement, compromise or consent includes an
unconditional release of each indemnified party from all liability arising out
of such litigation, investigation, proceeding or claim.

                                       13

<PAGE>

     (d)  If at any time an indemnified party shall have requested an
indemnifying party to reimburse the indemnified party for fees and expenses of
counsel, such indemnifying party agrees that it shall be liable for any
settlement of the nature contemplated by Section 7(a)(ii) effected without its
written consent only if (i) such settlement is entered into more that 45 days
after receipt by such indemnifying party of the aforesaid request, (ii) such
indemnifying party shall have received notice of the terms of such settlement at
least 30 days prior to such settlement being entered into and (iii) such
indemnifying party shall not have reimbursed such indemnified party in
accordance with such request prior to the date of such settlement.

     SECTION 8. CONTRIBUTION.

     (a)  If the indemnification provided for in Section 7 hereof is for any
reason unavailable to or insufficient to hold harmless an indemnified party in
respect of any losses, liabilities, claims, damages or expenses referred to
therein, then each indemnifying party, in lieu of such indemnification, shall
contribute to the aggregate amount of such losses, liabilities, claims, damages
and expenses incurred by such indemnified party, as incurred, (i) in such
proportion as is appropriate to reflect the relative benefits received by the
Company on the one hand and the Remarketing Agent on the other from the offering
of the Remarketed Senior Notes or (ii) if the allocation provided by clause (i)
is not permitted by applicable law, in such proportions as is appropriate to
reflect not only the relative benefits referred to in clause (i) above but also
the relative fault of the Company on the one hand and the Remarketing Agent on
the other hand in connection with the statements or omissions which resulted in
such losses, liabilities, claims, damages or expenses, as well as any relevant
equitable considerations.

     The relative benefits received by the Company on one hand and the
Remarketing Agent on the other Band in connection with the Remarketing shall be
deemed to be in the same proportions as the aggregate principal amount of the
Remarketed Senior Notes less the fee paid to the Remarketing Agent on the one
hand and the fee paid to the Remarketing Agent on the other hand bear to the
aggregate principal amount of the Remarketed Senior Notes.

     The relative fault of the Company on the one hand and the Remarketing Agent
on the other hand shall be determined by reference to, among other things,
whether the untrue or alleged untrue statement of a material fact or the
omission or alleged omission to state a material fact relates to information
supplied by the Company or the Remarketing Agent and the parties' relative
intent, knowledge, access to information and opportunity to correct or prevent
such statement or omission.

     The Company and the Remarketing Agent agree that it would not be just and
equitable if contribution pursuant to this Section 8(a) were determined by pro
rata allocation or by any other method of allocation which does not take account
of the equitable considerations referred to above in this Section 8(a). The
aggregate amount of losses, liabilities, claims, damages and expenses incurred
by an indemnified party and referred to above in this Section 8(a) shall be
deemed to include, subject to the limitations set forth above, any legal or
other expenses reasonably incurred by such indemnified party in investigating,
preparing or defending against any litigation, or any investigation or
proceeding by any governmental agency or body, commenced or threatened, or any
claim whatsoever based upon any such untrue or alleged untrue statement or
omission or alleged omission.

                                       14

<PAGE>

     Notwithstanding the provisions of this subsection (a), the Remarketing
Agent shall not be required to contribute any amount in excess of the amount by
which the fees received by it under Section 4 exceeds the amount of any damages
which the Remarketing Agent has otherwise been required to pay by reason of such
untrue or alleged untrue statement or omission or alleged omission.

     No person guilty of fraudulent misrepresentation (within the meaning of
Section 11 (f) of the Securities Act) shall be entitled to contribution from any
person who was not guilty of such fraudulent misrepresentation.

     (b)  For purposes of this Section 8, each person, if any, who controls the
Remarketing Agent within the meaning of Section 15 of the Securities Act or
Section 20 of the Exchange Act shall have the same rights to contribution as the
Remarketing Agent; each director of the Company, each officer of the Company who
signed the Registration Statement, and each person, if any, who controls the
Company within the meaning of Section 15 of the Securities Act or Section 20 of
the Exchange Act shall have the same rights to contribution as the Company.

     (c)  The indemnity and contribution provisions contained in Section 7 and
this Section 8 and the representations, warranties and other statements of the
Company contained in this Agreement shall remain in full force and effect,
regardless of any investigation (or any statement as to the results thereof)
made by or on behalf of the Remarketing Agent or any person controlling the
Remarketing Agent, or the Company, its officers or director or any controlling
person of the Company, and the completion of the Remarketing.

     SECTION 9. RESIGNATION AND REMOVAL OF THE REMARKETING AGENT.

     The Remarketing Agent Candidates may resign and be discharged from their
duties and obligations hereunder, and the Company may remove any of the
Remarketing Agent Candidates by giving 30 days' prior written notice, in the
case of a resignation, to the Company and the Depositary and, in the case of a
removal, to the removed Remarketing Agent Candidate and the Depositary;
provided, however, that if only one Remarketing Agent Candidate remains:

     (a)  such Remarketing Agent Candidate may not resign without reasonable
cause; and

     (b)  no such resignation nor any such removal shall become effective until
the Company shall have appointed at least one nationally recognized
broker-dealer as successor Remarketing Agent and such successor Remarketing
Agent shall have entered into a remarketing agreement with the Company, in which
it shall have agreed to conduct the Remarketing in accordance with the
Transaction Documents in all material respects.

     In any such case, the Company will use commercially reasonable efforts to
appoint a successor Remarketing Agent and enter into such a remarketing
agreement with such person as soon as reasonably practicable. The provisions of
Section 7 and Section 8 shall survive the resignation or removal of any
Remarketing Agent pursuant to this Agreement.

                                       15

<PAGE>

     SECTION 10. DEALING IN SECURITIES.

     The Remarketing Agent, when acting as a Remarketing Agent or in its
individual or any other capacity, may, to the extent permitted by law, buy,
sell, hold and deal in any of the Remarketed Senior Notes, Corporate Units,
Treasury Units or any of the securities of the Company (together, the
"Securities"). The Remarketing Agent may exercise any vote or join in any action
which any beneficial owner of such Securities may be entitled to exercise or
take pursuant to the Indenture 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.

     SECTION 11. REMARKETING AGENT'S PERFORMANCE; DUTY OF CARE.

     The duties and obligations of the Remarketing Agent shall be determined
solely by the express provisions of this Agreement and the Transaction
Documents. No implied covenants or obligations of or against the Remarketing
Agent shall be read into this Agreement or any of the Transaction Documents. In
the absence of bad faith on the part of the Remarketing Agent, the Remarketing
Agent may conclusively rely upon any document furnished to it, as to the truth
of the statements expressed in any of such documents. The Remarketing Agent
shall be protected in acting upon any document or communication reasonably
believed by it to have been signed, presented or made by the proper party or
parties except as otherwise set forth herein. The Remarketing Agent, acting
under this Agreement, shall incur no liability to the Company or to any holder
of Remarketed Senior Notes in its individual capacity or as Remarketing Agent
for any action or failure to act, on its part in connection with a Remarketing
or otherwise, except if such liability is judicially determined to have resulted
from its failure to comply with the material terms of this Agreement or bad
faith, gross negligence or willful misconduct on its part. The provisions of
this Section 11 shall survive the termination of this Agreement and shall
survive the resignation or removal of any Remarketing Agent pursuant to this
Agreement.

     SECTION 12. TERMINATION.

     This Agreement shall automatically terminate (i) as to the Remarketing
Agent on the effective date of the resignation or removal of the Remarketing
Agent pursuant to Section 9 and (ii) on the earlier of (x) any Special Event
Redemption Date and (y) the Purchase Contract Settlement Date. If this Agreement
is terminated pursuant to any of the other provisions hereof, except as
otherwise provided herein, the Company shall not be under any liability to the
Remarketing, Agent and the Remarketing Agent shall not be under any liability to
the Company, except that if this Agreement is terminated by the Remarketing
Agent because of any failure or refusal on the part of the Company to comply
with the terms or to fulfill any of the conditions of this Agreement, the
Company will reimburse the Remarketing Agent for all of its out-of-pocket
expenses (including the fees and disbursements of its counsel) reasonably
incurred by it. Sections 7, 8 and 11 hereof shall survive the termination of
this Agreement or the resignation or removal of the Remarketing Agent.

Remarketing Agent and the person or persons, if any, who control the Remarketing

Agreement shall be deemed to be for the benefit of the Company's directors and
officers who sign the Registration Statement, if any, and any person controlling
the Company within the meaning of Section 15 of the Securities Act. Nothing
contained in this Agreement is intended or shall be construed to give any
person, other than the persons referred to herein, any legal or equitable right,
remedy or claim under or in respect of this Agreement or any provision contained
herein.

     SECTION 15. SURVIVAL.

     The respective indemnities, representations, warranties and agreements of
the Company and the Remarketing Agent contained in this Agreement or made by or

<PAGE>

force and effect, regardless of any investigation made by or on behalf of any of
them or any person controlling any of them.

     SECTION 16. GOVERNING LAW.

     Agreement shall be governed by, and construed in accordance with, the laws
of New York, without regard to conflicts of laws principles.

     SECTION 17. JUDICIAL PROCEEDINGS.

     (a)  Each party hereto expressly accepts and irrevocably submits to the
non-exclusive jurisdiction of the United States Federal or New York State court
sitting in the Borough of Manhattan, The City of New York, New York, over any
suit, action or proceeding arising out of or relating to this Agreement or the
Remarketed Senior Notes. To the fullest extent it may effectively do so under
applicable law, each party hereto irrevocably waives and agrees not to assert,
by way of motion, as a defense or otherwise, any claim that it is not subject to
the jurisdiction of any such court, any objection that it may now or hereafter
have to the laying of the venue of any such suit, action or proceeding brought
in any such court and any claim that any such suit, action or proceeding brought
in any such court has been brought in an inconvenient forum.

     (b)  Each party hereto agrees, to the fullest extent that it may
effectively do so under applicable law, that a judgment in any suit, action or
proceeding of the nature referred to in Section 17(a) brought in any such court
shall be conclusive and binding upon such party, subject to rights of appeal and
may be enforced in the courts of the United States of America or the State of
New York (or any other court the jurisdiction to which the Company is or may be
subject) by a suit upon such judgment.

     SECTION 18. COUNTERPARTS.

     This Agreement may be executed in one or more counterparts and, if executed
in more than one counterpart, the executed counterparts shall each be deemed to
be an original but all such counterparts shall together constitute one and the
same instrument.

     SECTION 19. HEADINGS.

     The headings herein are inserted for convenience of reference only and are
not intended to be part of, or to affect the meaning or interpretation of, this
Agreement.

     SECTION 20. SEVERABILITY.

     If any provision of this Agreement shall be held or deemed to be or shall,
in fact, be invalid, inoperative or unenforceable as applied in any particular
case in any or all jurisdictions because it conflicts with any provisions of any
constitution, statute, rule or public policy or for any other reason, then, to
the extent permitted by law, such circumstances shall not have the effect of
rendering the provision in question invalid, inoperative or unenforceable in any
other case, circumstance or jurisdiction, or of rendering any other provision or
provisions of this Agreement invalid, inoperative or unenforceable to any extent
whatsoever.
