are a component of the Corporate PIES) has not elected to make an

 
                                                                              16


effective Cash Settlement by notifying the Purchase Contract Agent in the manner
provided for in Section 5.4(a)(i) in the Purchase Contract Agreement, or has
given such notice but failed to deliver the required cash prior to 11:00 A.M.,
New York City time, on the fifth Business Day immediately preceding the Purchase
Contract Settlement Date, such Holder shall be deemed to have elected to pay for
the shares of Common Stock to be issued under such Purchase Contract(s) from the
Proceeds of the related Pledged Preferred Securities or Pledged Debentures. In
such event, the Collateral Agent shall instruct the Securities Intermediary to
Transfer the related Pledged Preferred Securities or Pledged Debentures to the
Remarketing Agent for remarketing. Upon receiving such Pledged Preferred
Securities or Pledged Debentures, the Remarketing Agent, pursuant to the terms
of the Remarketing Agreement, will use its reasonable efforts to remarket such
Pledged Preferred Securities or Pledged Debentures on such date at a price of
100% of the aggregate liquidation amount of such Pledged Preferred Securities or
aggregate principal amount of such Pledged Debentures, as the case may be. The
Remarketing Agent will deposit the entire amount of the Proceeds of such
remarketing in the Collateral Account. On the Purchase Contract Settlement Date,
the Collateral Agent shall instruct the Securities Intermediary to apply the
Proceeds from such remarketing equal to the aggregate liquidation amount of such
Pledged Preferred Securities or aggregate principal amount of such Pledged
Debentures, as the case may be, to satisfy in full the obligations of such
Holders of Corporate PIES to pay the Purchase Price to purchase the Common Stock
under the related Purchase Contracts. If the Remarketing Agent advises the
Collateral Agent in writing that it cannot remarket the related Pledged
Preferred Securities or Pledged Debentures, as the case may be, of such Holders
of Corporate PIES at a price equal to 100% of the aggregate liquidation amount
of such Pledged Preferred Securities or aggregate principal amount of such
Pledged Debentures, thus resulting in a Failed Remarketing and an event of
default under the Purchase Contract Agreement and hereunder, the Collateral
Agent, for the benefit of the Company shall, at the written direction of the
Company, dispose of the Pledged Preferred Securities or Pledged Debentures, as
the case may be, in accordance with applicable law and satisfy in full, from
such disposition, such Holders' obligation to pay the Purchase Price for the
Common Stock.

      (b) If a Holder of Treasury PIES or Corporate PIES (if a Tax Event
Redemption has occurred) has not elected to make an effective cash settlement by
notifying the Purchase Contract Agent in the manner provided for in Section
5.4(d)(i) of the Purchase Contract Agreement, or has given such notice but
failed to make such payment in the manner required by Section 5.4(d)(ii) of the
Purchase Contract Agreement, such Holder shall be deemed to have elected to pay
for the shares of Common Stock to be issued under such Purchase Contract(s) from
the Proceeds of the related Pledged Treasury Securities or such Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio, as the case may be. On the Business Day immediately
prior to the Purchase Contract Settlement Date, the Securities Intermediary, at
the written direction of the Collateral Agent, shall invest the Cash Proceeds of
the maturing Pledged Treasury Securities or such Applicable Ownership Interest
(as specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as the case may be, in Permitted Investments. Without receiving any
instruction from any such Holder of Treasury PIES or Corporate PIES, the
Collateral Agent shall apply the Proceeds of the related Pledged Treasury
Securities or such Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio to the settlement of such
Purchase Contracts on the Purchase Contract Settlement

 
                                                                              17


Date. In the event the sum of the Proceeds from the related Pledged Treasury
Securities or such Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio and the investment
earnings from the investment in Permitted Investments is in excess of the
aggregate Purchase Price of the Purchase Contracts being settled thereby, the
Collateral Agent shall instruct the Securities Intermediary to distribute such
excess, when received, to the Purchase Contract Agent for the benefit of such
Holders for distribution to such Holders in accordance with their respective
interests.

      Section 5.8 Tax Event Redemption. If the Tax Event Redemption shall occur
prior to the Purchase Contract Settlement Date, the Securities Intermediary
shall apply the Redemption Amount to purchase the Treasury Portfolio and the
Securities Intermediary shall credit the Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio to the Collateral Account and shall transfer the Applicable Ownership
Interest (as specified in clause (B) of the definition of such term) of the
Treasury Portfolio to the Purchase Contract Agent for distribution to the
Holders of the Corporate PIES. Upon credit to the Collateral Account of the
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio having a Value equal to the liquidation
amount of the Pledged Preferred Securities or the aggregate principal amount of
the Pledged Debentures, the Securities Intermediary shall release the Pledged
Preferred Securities or the Pledged Debentures, as applicable, from the
Collateral Account and shall promptly transfer the Pledged Preferred Securities
to the Trust and the Pledged Debentures to the Finance Subsidiary, as
applicable.

      Section 6. Voting Rights -- Trust Preferred Securities and Pledged
Debentures. The Purchase Contract Agent may exercise, or refrain from
exercising, any and all voting and other consensual rights pertaining to the
Pledged Preferred Securities or the Pledged Debentures or any part thereof for
any purpose not inconsistent with the terms of this Agreement and in accordance
with the terms of the Purchase Contract Agreement; provided, that the Purchase
Contract Agent shall not exercise or, as the case may be, shall not refrain from
exercising such right if, in the judgment of the Purchase Contract Agent, such
action would impair or otherwise have a material adverse effect on the value of
all or any of the Pledged Preferred Securities or the Pledged Debentures; and
provided, further, that the Purchase Contract Agent shall give the Company and
the Collateral Agent at least five days' prior written notice of the manner in
which it intends to exercise, or its reasons for refraining from exercising, any
such right. Upon receipt of any notices and other communications in respect of
any Pledged Preferred Securities or any Pledged Debentures, including notice of
any meeting at which holders of Trust Preferred Securities or Debentures are
entitled to vote or solicitation of consents, waivers or proxies of holders of
Trust Preferred Securities or Debentures, the Collateral Agent shall use
reasonable efforts to send promptly to the Purchase Contract Agent such notice
or communication, and as soon as reasonably practicable after receipt of a
written request therefor from the Purchase Contract Agent, execute and deliver
to the Purchase Contract Agent such proxies and other instruments in respect of
such Pledged Preferred Securities or Pledged Debentures (in form and substance
satisfactory to the Collateral Agent) as are prepared by the Purchase Contract
Agent with respect to the Pledged Preferred Securities or Pledged Debentures.

      Section 7. Rights and Remedies; Distribution of the Debentures; Tax Event
Redemption

 
                                                                              18


      Section 7.1 Rights and Remedies of the Collateral Agent. (a) In addition
to the rights and remedies specified in Section 5.5 hereof or otherwise
available at law or in equity, after an event of default (as specified in
Section 7.1(b) below) hereunder the Collateral Agent shall have all of the
rights and remedies with respect to the Collateral of a secured party under the
Code (whether or not the Code is in effect in the jurisdiction where the rights
and remedies are asserted) and the TRADES Regulations and such additional rights
and remedies to which a secured party is entitled under the laws in effect in
any jurisdiction where any rights and remedies hereunder may be asserted.
Without limiting the generality of the foregoing, such remedies may include, to
the extent permitted by applicable law, (i) retention of the Pledged Preferred
Securities or Pledged Debentures in full satisfaction of the Holders'
obligations under the Purchase Contracts or (ii) sale of the Pledged Preferred
Securities or Pledged Debentures in one or more public or private sales.

      (b) Without limiting any rights or powers otherwise granted by this
Agreement to the Collateral Agent, in the event the Collateral Agent is unable
to make payments to the Company on account of the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio or on account of principal payments of any Pledged
Treasury Securities as provided in Section 3 hereof, in satisfaction of the
Obligations of the Holder of the Securities of which such Pledged Treasury
Securities or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio, as
applicable, is a part under the related Purchase Contracts, the inability to
make such payments shall constitute an event of default hereunder and the
Collateral Agent shall have and may exercise, with reference to such Pledged
Treasury Securities or such appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as applicable, and such obligations of such Holder, any and all of
the rights and remedies available to a secured party under the Code and the
TRADES Regulations after default by a debtor, and as otherwise granted herein or
under any other law.

      (c) Without limiting any rights or powers otherwise granted by this
Agreement to the Collateral Agent, the Collateral Agent is hereby irrevocably
authorized to receive and collect all payments of (i) the liquidation amount of
or, cash distributions on, the Pledged Preferred Securities, (ii) the principal
amount of the Pledged Treasury Securities, (iii) the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio and (iv) the principal amount of the Pledged
Debentures, subject, in each case, to the provisions of Section 3 hereof, and as
otherwise granted herein.

      (d) The Purchase Contract Agent and each Holder of Securities, in the
event such Holder becomes the Holder of a Treasury PIES, agrees that, from time
to time, upon the written request of the Collateral Agent, the Purchase Contract
Agent or such Holder shall execute and deliver such further documents and do
such other acts and things as the Collateral Agent may reasonably request in
order to maintain the Pledge, and the perfection and priority thereof, and to
confirm the rights of the Collateral Agent hereunder. The Purchase Contract
Agent shall have no liability to any Holder for executing any documents or
taking any such acts requested by the Collateral Agent hereunder, except for
liability for its own negligent act, its own negligent failure to act or its own
willful misconduct.

 
                                                                              19


      Section 7.2 Substitution of Debentures. If the Trust shall have been
liquidated prior to the Purchase Contract Settlement Date, the Collateral Agent
shall transfer to the Securities Intermediary Debentures having a Value equal to
the liquidation amount of the Pledged Preferred Securities for credit to the
Collateral Account. Upon credit to the Collateral Account of such Debentures,
the Securities Intermediary shall release the Pledged Preferred Securities from
the Collateral Account and shall promptly transfer the same to the Trust.

      Section 7.3 Tax Event Redemption. Upon the occurrence of a Tax Event
Redemption prior to the Purchase Contract Settlement Date, the Redemption Price
payable on the Tax Event Redemption Date with respect to the Applicable
Principal Amount shall be credited to the Collateral Account by the Property
Trustee or, upon a dissolution of the Trust and the distribution of the related
Debentures, by the Debenture Trustee on or prior to 12:30 p.m., New York City
time, by federal funds check or wire transfer of immediately available funds.
The Collateral Agent is hereby authorized to present the Pledged Preferred
Securities or the Pledged Debentures for payment as may be required by their
respective terms. Upon receipt of such funds, the Pledged Preferred Securities
or Pledged Debentures, as the case may be, shall be released from the Collateral
Account. In the event such funds are credited to the Collateral Account, the
Collateral Agent, at the written direction of the Company, shall instruct the
Securities Intermediary to (a) apply an amount equal to the Redemption Amount of
such Redemption Price to purchase the Treasury Portfolio from the Quotation
Agent for credit to the Collateral Account and (b) promptly remit the remaining
portion of such Redemption Price to the Purchase Contract Agent for payment to
the Holders of Corporate PIES.

      Section 7.4 Substitutions. Whenever a Holder has the right to substitute
Treasury Securities, Trust Preferred Securities, Debentures or security
entitlements to any of them or the appropriate Applicable Ownership Interest of
the Treasury Portfolio, as the case may be, for financial assets held in the
Collateral Account, such substitution shall not constitute a novation of the
security interest created hereby.

      Section 8. Representations and Warranties; Covenants.

      Section 8.1 Representations and Warranties. The Holders from time to time,
acting through the Purchase Contract Agent as their attorney-in-fact (it being
understood that the Purchase Contract Agent shall not be liable for any
representation or warranty made by or on behalf of a Holder), hereby represent
and warrant to the Collateral Agent, which representations and warranties shall
be deemed repeated on each day a Holder Transfers Collateral that:

            (a)   such Holder has the power to grant a security interest in and
                  lien on the Collateral;

            (b)   such Holder is the sole beneficial owner of the Collateral
                  and, in the case of Collateral delivered in physical form, is
                  the sole holder of such Collateral and is the sole beneficial
                  owner of, or has the right to Transfer, the Collateral it
                  Transfers to the Securities Intermediary for credit to the
                  Collateral Account, free and clear of any security interest,
                  lien, encumbrance, call, liability to pay

 
                                                                              20


                  money or other restriction other than the security interest
                  and lien granted under Section 2 hereof;

            (c)   upon the Transfer of the Collateral to the Securities
                  Intermediary for credit to the Collateral Account, the
                  Collateral Agent, for the benefit of the Company, will have a
                  valid and perfected first priority security interest therein
                  (assuming that any central clearing operation or any
                  securities intermediary or other entity not within the control
                  of the Holder involved in the Transfer of the Collateral,
                  including the Collateral Agent and the Securities
                  Intermediary, gives the notices and takes the action required
                  of it hereunder and under applicable law for perfection of
                  that interest and assuming the establishment and exercise of
                  control pursuant to Section 4 hereof); and

            (d)   the execution and performance by the Holder of its obligations
                  under this Agreement will not result in the creation of any
                  security interest, lien or other encumbrance on the Collateral
                  other than the security interest and lien granted under
                  Section 2 hereof or violate any provision of any existing law
                  or regulation applicable to it or of any mortgage, charge,
                  pledge, indenture, contract or undertaking to which it is a
                  party or which is binding on it or any of its assets.

      Section 8.2 Covenants. The Holders from time to time, acting through the
Purchase Contract Agent as their attorney-in-fact (it being understood that the
Purchase Contract Agent shall not be liable for any covenant made by or on
behalf of a Holder), hereby covenant to the Collateral Agent that for so long as
the Collateral remains subject to the Pledge:

            (a)   neither the Purchase Contract Agent nor such Holders will
                  create or purport to create or allow to subsist any mortgage,
                  charge, lien, pledge or any other security interest whatsoever
                  over the Collateral or any part of it other than pursuant to
                  this Agreement; and

            (b)   neither the Purchase Contract Agent nor such Holders will sell
                  or otherwise dispose (or attempt to dispose) of the Collateral
                  or any part of it except for the beneficial interest therein,
                  subject to the Pledge hereunder, transferred in connection
                  with the Transfer of the Securities.

      Section 9. The Collateral Agent and the Securities Intermediary. It is
hereby agreed as follows:

      Section 9.1 Appointment, Powers and Immunities. The Collateral Agent shall
act as agent for the Company hereunder with such powers as are specifically
vested in the Collateral Agent by the terms of this Agreement, together with
such other powers as are reasonably incidental thereto. The Collateral Agent:
(a) shall have no duties or responsibilities except those expressly set forth in

 
                                                                              21


this Agreement and no implied covenants or obligations shall be inferred from
this Agreement against the Collateral Agent, nor shall the Collateral Agent be
bound by the provisions of any agreement by any party hereto beyond the specific
terms hereof; (b) shall not be responsible for any recitals contained in this
Agreement, or in any certificate or other document referred to or provided for
in, or received by it under, this Agreement, the Securities or the Purchase
Contract Agreement, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement (other than as against the
Collateral Agent), the Securities or the Purchase Contract Agreement or any
other document referred to or provided for herein or therein or for any failure
by the Company or any other Person (except the Collateral Agent) to perform any
of its obligations hereunder or thereunder or for the perfection, priority or,
except as expressly required hereby, maintenance of any security interest
created hereunder; (c) shall not be required to initiate or conduct any
litigation or collection proceedings hereunder (except pursuant to directions
furnished under Section 9.2 hereof, subject to Section 9.6 hereof); (d) shall
not be responsible for any action taken or omitted to be taken by it hereunder
or under any other document or instrument referred to or provided for herein or
in connection herewith or therewith, except for its own negligence or willful
misconduct; and (e) shall not be required to advise any party as to selling or
retaining, or taking or refraining from taking any action with respect to, any
securities or other property deposited hereunder. Subject to the foregoing,
during the term of this Agreement, the Collateral Agent shall take all
reasonable action in connection with the safekeeping and preservation of the
Collateral hereunder.

      No provision of this Agreement shall require the Collateral Agent to
expend or risk its own funds or otherwise incur any financial liability in the
performance of any of its duties hereunder. In no event shall the Collateral
Agent be liable for any amount in excess of the Value of the Collateral.
Notwithstanding the foregoing, each of the Collateral Agent and the Securities
Intermediary in its individual capacity hereby waives any right of setoff,
bankers lien, liens or perfection rights as securities intermediary or any
counterclaim with respect to any of the Collateral.

      Section 9.2 Instructions of the Company. The Company shall have the right,
by one or more instruments in writing executed and delivered to the Collateral
Agent, to direct the time, method and place of conducting any proceeding for the
realization of any right or remedy available to the Collateral Agent, or of
exercising any power conferred on the Collateral Agent, or to direct the taking
or refraining from taking of any action authorized by this Agreement; provided,
however, that (i) such direction shall not conflict with the provisions of any
law or of this Agreement and (ii) the Collateral Agent shall be adequately
indemnified as provided herein. Nothing in this Section 9.2 shall impair the
right of the Collateral Agent in its discretion to take any action or omit to
take any action which it deems proper and which is not inconsistent with such
direction.

      Section 9.3 Reliance by Collateral Agent and Securities Intermediary. Each
of the Securities Intermediary and the Collateral Agent shall be entitled to
rely upon any certification, order, judgment, opinion, notice or other
communication (including, without limitation, any thereof by telephone,
telecopy, telex or facsimile) believed by it to be genuine and correct and to
have been signed or sent by or on behalf of the proper Person or Persons
(without being required to determine the correctness of any fact stated
therein), and upon advice and statements of legal counsel and other experts
selected by the Collateral Agent and the Securities Intermediary. As to any
matters not ex-

 
                                                                              22


pressly provided for by this Agreement, the Collateral Agent and the Securities
Intermediary shall in all cases be fully protected in acting, or in refraining
from acting, hereunder in accordance with instructions given by the Company in
accordance with this Agreement.

      Section 9.4 Rights in Other Capacities. The Collateral Agent and the
Securities Intermediary and their affiliates may (without having to account
therefor to the Company) accept deposits from, lend money to, make their
investments in and generally engage in any kind of banking, trust or other
business with the Purchase Contract Agent, any other Person interested herein
and any Holder of Securities (and any of their respective subsidiaries or
affiliates) as if it were not acting as the Collateral Agent, and the Collateral
Agent, the Securities Intermediary and their affiliates may accept fees and
other consideration from the Purchase Contract Agent and any Holder of
Securities without having to account for the same to the Company; provided that
each of the Securities Intermediary and the Collateral Agent covenants and
agrees with the Company that it shall not accept, receive or permit there to be
created in favor of itself and shall take no affirmative action to permit there
to be created in favor of any other Person, any security interest, lien or other
encumbrance of any kind in or upon the Collateral other than the lien created by
the Pledge.

      Section 9.5 Non-Reliance on Collateral Agent and Securities Intermediary.
Neither the Securities Intermediary nor the Collateral Agent shall be required
to keep itself informed as to the performance or observance by the Purchase
Contract Agent or any Holder of Securities of this Agreement, the Purchase
Contract Agreement, the Securities or any other document referred to or provided
for herein or therein or to inspect the properties or books of the Purchase
Contract Agent or any Holder of Securities. Neither the Collateral Agent nor the
Securities Intermediary shall have any duty or responsibility to provide the
Company with any credit or other information concerning the affairs, financial
condition or business of the Purchase Contract Agent or any Holder of Securities
(or any of their respective affiliates) that may come into the possession of the
Collateral Agent or the Securities Intermediary or any of their respective
affiliates.

      Section 9.6 Compensation and Indemnity. The Company agrees: (i) to pay the
Collateral Agent and the Securities Intermediary from time to time such
compensation as shall be agreed in writing between the Company and the
Collateral Agent or the Securities Intermediary, as the case may be, for all
services rendered by them hereunder and (ii) to indemnify the Collateral Agent
and the Securities Intermediary for, and to hold each of them harmless from and
against, any loss, liability or reasonable out-of-pocket expense incurred
without negligence, willful misconduct or bad faith on 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.

      Section 9.7 Failure to Act. In the event of any ambiguity in the
provisions of this Agreement or any dispute between or conflicting claims by or
among the parties hereto or any other Person with respect to any funds or
property deposited hereunder, the Collateral Agent and the Securities
Intermediary shall be entitled, after prompt notice to the Company and the
Purchase Contract Agent, at its sole option, to refuse to comply with any and
all claims, demands or instructions with respect

 
                                                                              23


to such property or funds so long as such dispute or conflict shall continue,
and the Collateral Agent and the Securities Intermediary shall not be or become
liable in any way to any of the parties hereto for its failure or refusal to
comply with such conflicting claims, demands or instructions. The Collateral
Agent and the Securities Intermediary shall be entitled to refuse to act until
either (i) such conflicting or adverse claims or demands shall have been finally
determined by a court of competent jurisdiction or settled by agreement between
the conflicting parties as evidenced in a writing satisfactory to the Collateral
Agent or the Securities Intermediary or (ii) the Collateral Agent or the
Securities Intermediary shall have received security or an indemnity
satisfactory to it sufficient to save it harmless from and against any and all
loss, liability or reasonable out-of-pocket expense which it may incur by reason
of its acting. The Collateral Agent and the Securities Intermediary may in
addition elect to commence an interpleader action or seek other judicial relief
or orders as the Collateral Agent or the Securities Intermediary may deem
necessary. Notwithstanding anything contained herein to the contrary, neither
the Collateral Agent nor the Securities Intermediary shall be required to take
any action that is in its opinion contrary to law or to the terms of this
Agreement, or which would in its opinion subject it or any of its officers,
employees or directors to liability.

      Section 9.8 Resignation of Collateral Agent and Securities Intermediary.
(a) Subject to the appointment and acceptance of a successor Collateral Agent as
provided below, (i) the Collateral Agent may resign at any time by giving notice
thereof to the Company and the Purchase Contract Agent as attorney-in-fact for
the Holders of Securities, (ii) the Collateral Agent may be removed at any time
by the Company and (iii) if the Collateral Agent fails to perform any of its
material obligations hereunder in any material respect for a period of not less
than 20 days after receiving written notice of such failure by the Purchase
Contract Agent and such failure shall be continuing, the Collateral Agent may be
removed by the Purchase Contract Agent. The Purchase Contract Agent shall
promptly notify the Company of any removal of the Collateral Agent pursuant to
clause (iii) of the immediately preceding sentence. Upon any such resignation or
removal, the Company shall have the right to appoint a successor Collateral
Agent. If no successor Collateral Agent shall have been so appointed and shall
have accepted such appointment within 30 days after the retiring Collateral
Agent's giving of notice of resignation or such removal, then the retiring
Collateral Agent may petition any court of competent jurisdiction for the
appointment of a successor Collateral Agent. The Collateral Agent shall be a
bank which has an office in New York, New York with a combined capital and
surplus of at least $50,000,000 and shall not be the Purchase Contract Agent or
any of its affiliates. Upon the acceptance of any appointment as Collateral
Agent hereunder by a successor Collateral Agent, such successor Collateral Agent
shall thereupon succeed to and become vested with all the rights, powers,
privileges and duties of the retiring Collateral Agent, and the retiring
Collateral Agent shall take all appropriate action to transfer any money and
property held by it hereunder (including the Collateral) to such successor
Collateral Agent. The retiring Collateral Agent shall, upon such succession, be
discharged from its duties and obligations as Collateral Agent hereunder. After
any retiring Collateral Agent's resignation hereunder as Collateral Agent, the
provisions of this Section 9 shall continue in effect for its benefit in respect
of any actions taken or omitted to be taken by it while it was acting as the
Collateral Agent.

      (b) Subject to the appointment and acceptance of a successor Securities
Intermediary as provided below, (i) the Securities Intermediary may resign at
any time by giving notice thereof to

 
                                                                              24


the Company and the Purchase Contract Agent as attorney-in-fact for the Holders
of Securities, (ii) the Securities Intermediary may be removed at any time by
the Company and (iii) if the Securities Intermediary fails to perform any of its
material obligations hereunder in any material respect for a period of not less
than 20 days after receiving written notice of such failure by the Purchase
Contract Agent and such failure shall be continuing, the Securities Intermediary
may be removed by the Purchase Contract Agent. The Purchase Contract Agent shall
promptly notify the Company of any removal of the Securities Intermediary
pursuant to clause (iii) of the immediately preceding sentence. Upon any such
resignation or removal, the Company shall have the right to appoint a successor
Securities Intermediary. If no successor Securities Intermediary shall have been
so appointed and shall have accepted such appointment within 30 days after the
retiring Securities Intermediary's giving of notice of resignation or such
removal, then the retiring Securities Intermediary may petition any court of
competent jurisdiction for the appointment of a successor Securities
Intermediary. The Securities Intermediary shall be a bank which has an office in
New York, New York with a combined capital and surplus of at least $50,000,000
and shall not be the Purchase Contract Agent or any of its affiliates. Upon the
acceptance of any appointment as Securities Intermediary hereunder by a
successor Securities Intermediary, such successor Securities Intermediary shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Securities Intermediary, and the retiring Securities
Intermediary shall take all appropriate action to transfer any money and
property held by it hereunder (including the Collateral) to such successor
Securities Intermediary. The retiring Securities Intermediary shall, upon such
succession, be discharged from its duties and obligations as Securities
Intermediary hereunder. After any retiring Securities Intermediary's resignation
hereunder as Securities Intermediary, the provisions of this Section 9 shall
continue in effect for its benefit in respect of any actions taken or omitted to
be taken by it while it was acting as the Securities Intermediary.

      Section 9.9 Right to Appoint Agent or Advisor. The Collateral Agent shall
have the right to appoint agents or advisors in connection with any of its
duties hereunder, and the Collateral Agent shall not be liable for any action
taken or omitted by, or in reliance upon the advice of, such agents or advisors
selected in good faith. The appointment of agents pursuant to this Section 9.9
shall be subject to prior consent of the Company, which consent shall not be
unreasonably withheld.

      Section 9.10 Survival. The provisions of this Section 9 shall survive
termination of this Agreement and the resignation or removal of the Collateral
Agent or the Securities Intermediary.

      Section 9.11 Exculpation. Anything in this Agreement to the contrary
notwithstanding, in no event shall the Collateral Agent or the Securities
Intermediary or their officers, directors, employees or agents be liable under
this Agreement to any third party for indirect, special, punitive, or
consequential loss or damage of any kind whatsoever, including lost profits,
whether or not the likelihood of such loss or damage was known to the Collateral
Agent or the Securities Intermediary, or any of them, incurred without any act
or deed that is found to be attributable to gross negligence or willful
misconduct on the part of the Collateral Agent or the Securities Intermediary.

Section 10. Amendment

 
                                                                              25


      Section 10.1 Amendment Without Consent of Holders. Without the consent of
any Holders, the Company, the Collateral Agent, the Securities Intermediary and
the Purchase Contract Agent, at any time and from time to time, may amend this
Agreement, in form satisfactory to the Company, the Collateral Agent, the
Securities Intermediary and the Purchase Contract Agent, for any of the
following purposes:

            (1) to evidence the succession of another Person to the Company, and
      the assumption by any such successor of the covenants of the Company;

            (2) to add to the covenants of the Company for the benefit of the
      Holders, or to surrender any right or power herein conferred upon the
      Company so long as such covenants or such surrender do not adversely
      affect the validity, perfection or priority of the Pledge created
      hereunder;

            (3) to evidence and provide for the acceptance of appointment
      hereunder by a successor Collateral Agent, Securities Intermediary or
      Purchase Contract Agent; or

            (4) to cure any ambiguity (or formal defect), to correct or
      supplement any provisions herein which may be inconsistent with any other
      such provisions herein, or to make any other provisions with respect to
      such matters or questions arising under this Agreement, provided such
      action shall not adversely affect the interests of the Holders.

      Section 10.2 Amendment with Consent of Holders. With the consent of the
Holders of not less than a majority of the Purchase Contracts at the time
outstanding, by Act of said Holders delivered to the Company, the Purchase
Contract Agent, the Securities Intermediary or the Collateral Agent, as the case
may be, the Company, when duly authorized, the Purchase Contract Agent, the
Securities Intermediary and the Collateral Agent may amend this Agreement for
the purpose of modifying in any manner the provisions of this Agreement or the
rights of the Holders in respect of the Securities; provided, however, that no
such supplemental agreement shall, without the unanimous consent of the Holders
of each Outstanding Security adversely affected thereby,

            (1) change the amount or type of Collateral underlying a Security
      (except for the rights of holders of Corporate PIES to substitute the
      Treasury Securities for the Pledged Preferred Securities, the Pledged
      Debentures or the appropriate Applicable Ownership Interest (as specified
      in clause (A) of the definition of such term) of the Treasury Portfolio,
      as the case may be, or the rights of Holders of Treasury PIES to
      substitute Trust Preferred Securities, Debentures or the appropriate
      Applicable Ownership Interest (as specified in clause (A) of the
      definition of such term) of the Treasury Portfolio, as applicable, for the
      Pledged Treasury Securities), impair the right of the Holder of any
      Security to receive distributions on the underlying Collateral or
      otherwise adversely affect the Holder's rights in or to such Collateral;
      or

 
                                                                              26


            (2) otherwise effect any action that would require the consent of
      the Holder of each Outstanding Security affected thereby pursuant to the
      Purchase Contract Agreement if such action were effected by an agreement
      supplemental thereto; or

            (3) reduce the percentage of Purchase Contracts the consent of whose
      Holders is required for any such amendment;

provided that if any amendment or proposal referred to above would adversely
affect only the Corporate PIES or the Treasury PIES, then only the affected
class of Holder as of the record date for the Holders entitled to vote thereon
will be entitled to vote on such amendment or proposal, and such amendment or
proposal shall not be effective except with the consent of Holders of not less
than a majority of such class; provided that the unanimous consent of the
Holders of each outstanding Purchase Contract of such class affected thereby
shall be required to approve any amendment or proposal specified in clauses
(1) - (3) above.

It shall not be necessary for any Act of Holders under this Section to approve
the particular form of any proposed amendment, but it shall be sufficient if
such Act shall approve the substance thereof.

      Section 10.3 Execution of Amendments. In executing any amendment permitted
by this Section, the Collateral Agent, the Securities Intermediary and the
Purchase Contract Agent shall be entitled to receive and (subject to Section 7.1
of the Purchase Contract Agreement with respect to the Purchase Contract Agent)
shall be fully protected in relying upon, an Opinion of Counsel stating that the
execution of such amendment is authorized or permitted by this Agreement and
that all conditions precedent, if any, to the execution and delivery of such
amendment have been satisfied.

      Section 10.4 Effect of Amendments. Upon the execution of any amendment
under this Section, this Agreement shall be modified in accordance therewith,
and such amendment shall form a part of this Agreement for all purposes; and
every Holder of Certificates theretofore or thereafter authenticated, executed
on behalf of the Holders and delivered under the Purchase Contract Agreement
shall be bound thereby.

      Section 10.5 Reference to Amendments. Certificates authenticated, executed
on behalf of the Holders and delivered after the execution of any amendment
pursuant to this Section may, and shall if required by the Collateral Agent or
the Purchase Contract Agent, bear a notation in form approved by the Purchase
Contract Agent and the Collateral Agent as to any matter provided for in such
amendment. If the Company shall so determine, new Security Certificates so
modified as to conform, in the opinion of the Collateral Agent, the Purchase
Contract Agent and the Company, to any such amendment may be prepared and
executed by the Company and authenticated, executed on behalf of the Holders and
delivered by the Purchase Contract Agent in accordance with the Purchase
Contract Agreement in exchange for Outstanding Security Certificates.

 
                                                                              27

any of its agents to exercise, and no course of dealing with respect to, and no
