of the Company in Section 3 are true and correct on and as of the applicable
Remarketing Date and the Company has performed in all material respects all
covenants and agreements contained herein to be performed on its part at or

                                        9

<PAGE>

prior to such Remarketing Date; and (iii) the Registration Statement, as of its
effective date, and the Remarketing Materials, as of their respective dates, did
not contain any untrue statement of a material fact and did not omit to state
any material fact required to be stated therein or necessary to make the'
statements therein not misleading and the Prospectus did not contain any untrue
statement of material fact or omit to state a material fact required to be
stated therein or necessary to make the statements therein, in light of the
circumstances under which they were made, not misleading.

        (e)     On the applicable Remarketing Date, the Remarketing Agent shall
have received a letter addressed to the Remarketing Agent and dated such date,
in form and substance satisfactory to the Remarketing Agent, of the independent
accountants of the Company, containing statements and information of the type
ordinarily included in accountants' "comfort letters" with respect to certain
financial information contained in the Remarketing Materials, if any.

        (f)     Outside counsels for the Company reasonably acceptable to the
Remarketing Agent shall have furnished to the Remarketing Agent its (or their)
opinion(s), addressed to the Remarketing Agent and dated the applicable
Remarketing Date, in form and substance reasonably satisfactory to the
Remarketing Agent addressing such matters as are set forth in such counsels'
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 Subordinated Notes shall not have been called for redemption

on or 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, 7 and 9 shall at all times be effective and shall survive such

        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

                                       10

<PAGE>

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 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 Subordinated Notes to such person,
and if the Prospectus (as so amended or supplemented) would have cured

                                       11

<PAGE>

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.

        (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)

                                       12

<PAGE>

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 Subordinated 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 Subordinated 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 Subordinated 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.

        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

                                       13

<PAGE>

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.

        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 Subordinated Notes, Corporate
Units, Treasury Units or any of the securities of the

                                       14

<PAGE>

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 Subordinated 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.

        SECTION 13. NOTICES.

        All statements, requests, notices and agreements hereunder shall be in
writing, and:

        (a)     ____________________________________________________;

        (b)     ____________________________________________________;

                                       15

        SECTION 14. PERSONS ENTITLED TO BENEFIT OF AGREEMENT.

        This Agreement shall inure to the benefit of and be binding upon each
party hereto and its respective successors. This Agreement and the terms and
provisions hereof are for the sole benefit of only those persons, except that
(x) the representations, warranties, indemnities and agreements of the Company
contained in this Agreement shall also be deemed to be for the benefit of the
Remarketing Agent and the person or persons, if any, who control the Remarketing
Agent within the meaning of Section 15 of the Securities Act and (y) the
indemnity agreement of the Remarketing Agent contained in Section 7(b) of this
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 on behalf of them, respectively, pursuant to this Agreement, shall survive
any Remarketing and shall remain in full 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 Subordinated Notes. To the fullest extent it may effectively do
so under applicable law, each party hereto irrevocably waives and agrees not to

                                       16

<PAGE>

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.

        SECTION 21. AMENDMENTS.

        This Agreement may be amended by an instrument in writing signed by the
parties hereto. Each of the Company and the Purchase Contract Agent agrees that
it will not enter cause or permit any amendment or modification of the
