Remarketing Agent, upon confirmation of deposit by the Remarketing Agent of the
Proceeds of such Remarketing in the Collateral Account.  On the Purchase
Contract Settlement Date, the Collateral Agent shall, in consultation with the

such Holder’s obligation to pay the aggregate Price for the shares of Common
Stock or Preferred Stock, as applicable, to be issued under the Purchase
Contracts underlying such Corporate Units in full satisfaction of such Holders’
obligations under the Purchase Contracts.   Following such set-off,
the Holder’s obligations to pay the Purchase Price for the shares of Common
Stock or Preferred Stock, as applicable, will be deemed to be satisfied in full,
and the Collateral Agent shall cause the Securities Intermediary to release the
Pledged Senior Notes from the Collateral Account and shall promptly transfer the
Pledged Senior Notes to the Company.  Thereafter, the Collateral Agent
shall promptly remit the remaining Proceeds of the Holder’s exercise of the Put

or Preferred Stock, as applicable, to be issued under such Purchase Contracts to
the Purchase Contract Agent for payment to the Holder of the Corporate Units to
which such Senior Notes relate.

10:30 a.m. on such date the Company shall otherwise instruct the Collateral
Agent in writing as to the type of Permitted Investments in which any Proceeds
shall be invested.  In no event shall the Collateral Agent be liable for
the selection of Permitted Investments or for investment losses incurred
thereon.  The Collateral Agent shall have no liability in respect of losses
incurred as a result of the failure of the Company to provide timely written
investment direction.  Without receiving any instruction from any Holder,
the Collateral Agent shall instruct the Securities Intermediary to remit the
Proceeds of the related Pledged Treasury Securities or Pledged Applicable
Ownership Interests, as the case may be, to the Company in settlement of such
Purchase Contracts on the Purchase Contract Settlement Date.  In the event
the sum of the Proceeds from the related Pledged Treasury Securities or Pledged
Applicable Ownership Interests, as the case may be, and the investment earnings
from the investment in Permitted Investments exceeds the aggregate Purchase
Price of the Purchase Contracts being settled thereby, the Collateral Agent
shall instruct the Securities Intermediary to transfer such excess, when
received, to the Purchase Contract Agent for distribution to
Holders.






(c)           On
or prior to 5:00 p.m. (New York City time) on the seventh Business Day
immediately preceding the Initial Remarketing Date, but no earlier than the
Payment Date immediately preceding such date, Holders of Separate Senior Notes
may elect to have their Separate Senior Notes remarketed under the Remarketing
Agreement, by delivering their Separate Senior Notes along with a notice of such
election, substantially in the form of Exhibit F hereto, to the
Collateral Agent.  The Collateral Agent, acting as Custodial Agent, shall
hold Separate Senior Notes in an account separate from the Collateral Account in
which the Pledged Securities shall be held.  Holders of Separate Senior
Notes electing to have their Separate Senior Notes remarketed will also have the
right to




13


withdraw
that election by written notice to the Collateral Agent, substantially in the
form of Exhibit G
hereto, on or prior to 5:00 p.m. (New York City time) on the seventh Business
Day immediately preceding the Initial Remarketing Date, upon which notice the
Custodial Agent shall return such Separate Senior Notes to such Holder. 
After such time, such election shall become an irrevocable election to have such
Separate Senior Notes remarketed in such Remarketing.




By 12:00
noon (New York City time) on the Business Day immediately preceding the Initial
Remarketing Date, the Custodial Agent shall notify the Remarketing Agent of the
aggregate principal amount of the Separate Senior Notes to be
remarketed.  In the event of a Successful Remarketing, the Custodial
Agent shall deliver all remarketed Separate Senior Notes to the Remarketing
Agent and the Remarketing Agent will remit to the Custodial Agent the remaining
portion of the proceeds of such Remarketing for payment to the Holders of the
remarketed Separate Senior Notes, in accordance with their respective
interests.  In the event of a Failed Final Remarketing, the Custodial Agent
will promptly return such Separate Senior Notes to the appropriate
Holders.




Section
5.08  Special Event
Redemption.   If the Collateral Agent receives written
notice that a Special Event Redemption has occurred while Senior Notes are still
credited to the Collateral Account, the Collateral Agent shall apply the
Redemption Amount to purchase the Treasury Portfolio, and the Collateral Agent
shall credit the Applicable Ownership Interests (as specified in clause (i) of
the definition of such term) in the Treasury Portfolio to the Collateral Account
and shall transfer the Applicable Ownership Interests (as specified in clause
(ii) of the definition of such term) in the Treasury Portfolio to the Purchase
Contract Agent for distribution to the Holders of the Corporate Units. 
Upon credit to the Collateral Account of the Applicable Ownership Interests (as
specified in clause (i) of the definition of such term) in the Treasury
Portfolio having a Value equal to the aggregate principal amount of the Pledged
Senior Notes, the Collateral Agent shall cause the Securities Intermediary to
release the Pledged Senior Notes from the Collateral Account and shall promptly
transfer the Pledged Senior Notes to the Company.

therefor from the Purchase Contract Agent, execute and deliver to the Purchase

Section
7.01  Rights and Remedies of the
Collateral Agent.

addition to the rights and remedies specified in Section 5.07 hereof or
otherwise available at law or in equity, after an event of default (as specified
in Section 7.01(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

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, (1) retention of the Pledged Senior
Notes, Pledged Treasury Securities or the applicable Pledged Applicable
Ownership Interests in full satisfaction of the Holders’ obligations under the
Purchase Contracts and the Purchase Contract Agreement or (2) sale of the
Pledged Senior Notes, Pledged Treasury Securities or the applicable Pledged
Applicable Ownership Interests in one or more public or private

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 applicable Pledged Applicable Ownership
Interests, or on account of principal payments of any Pledged Treasury
Securities as provided in Article 3 hereof, in
satisfaction of the Obligations of the Holder of the Units of which such
applicable Pledged Applicable Ownership Interests or such Pledged Treasury
Securities, as applicable, are 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 Pledged Applicable Ownership Interests, as
applicable, any and all of the rights and remedies available to a secured party
under the UCC 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 principal amount of the Pledged
Senior Notes, (ii) the principal amount of the Pledged Treasury Securities and
(iii) the principal amount of the Pledged Applicable Ownership Interests,
subject, in each case, to the provisions of Article 3 hereof, and as
otherwise granted herein.






(d)           The
Purchase Contract Agent and each Holder of Units agrees that, from time to time,
upon the written request of the Collateral Agent or the Purchase Contract Agent,
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 grossly negligent acts, its own grossly negligent failure to act or its
own willful misconduct.




Section
7.02  Special Event
Redemption.   Upon the occurrence of a Special Event
Redemption while Senior Notes are still credited to the Collateral Account, the
Collateral Agent is hereby authorized to present the Pledged Senior Notes for

Trustee to remit the Redemption Price to the Securities Intermediary for credit
to the Collateral Account on or prior to 12:30 p.m., New York City time on such
Special Event Redemption Date, by federal funds check or wire transfer of
immediately available funds.  Upon receipt of such funds, the Pledged
Senior Notes shall be released from the Collateral Account and promptly
transferred to the Company.  Upon the crediting of such funds to the
Collateral Account, the Collateral Agent, at the written direction of the
Company, shall instruct the Securities Intermediary to (a) apply an amount of
such funds equal to the Redemption Amount to purchase the Treasury Portfolio
from the Quotation Agent, (b) credit to the Collateral Account the Applicable
Ownership Interests (specified in clause (i) of the definition of such term) in

funds, if any, to the Purchase Contract Agent for payment to the Holders of
Corporate Units, in accordance with their respective interests and the Purchase
Contract Agreement.

a Special Event Redemption, an Early Settlement or a Cash Merger Early
Settlement has occurred prior to the Initial Remarketing Date, the Collateral

of Corporate Units, notify the Remarketing Agent of the aggregate principal
amount of Pledged Senior Notes to be remarketed.




Section

Omitted.




15


Section
7.05  Successful
Remarketing.   In the event of a Successful Remarketing,
the Collateral Agent shall on the Purchase Contract Settlement Date, at the
direction of the Company, instruct the Securities Intermediary to (i) Transfer
the Pledged Senior Notes to the Remarketing Agent upon confirmation of deposit
by the Remarketing Agent of the Proceeds of such Successful Remarketing in the
Collateral Account and (ii) remit a portion of such Proceeds equal to the
aggregate principal amount of the Pledged Senior Notes to satisfy in full the
Obligations of Holders of Corporate Units to pay the Purchase Price for the
shares of Common Stock or Preferred Stock, as applicable, under the related
Purchase Contracts, less the amount of any accrued and unpaid Contract
Adjustment Payments payable to such Holders, and to remit the balance of such
Proceeds, if any, to the Purchase Contract Agent for distribution to
Holders.  With respect to Separate Senior Notes, any Proceeds of such
Successful Remarketing attributable to the Separate Senior Notes will be
remitted to the Custodial Agent for payment to the holders of Separate Senior
Notes.  In the event of a Failed Final Remarketing, the Pledged Senior
Notes shall be redeposited into and remain credited to the Collateral Account
and Section 5.07 shall
apply.




Section
7.06  Substitutions.   Whenever
a Holder has the right to substitute Treasury Securities, Senior Notes or
security entitlements for any of them or the appropriate Applicable Ownership
Interest (as defined in clause (i) of the definition of such term) in 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
7.07  Legal
Holidays.   In case the Purchase Contract Settlement Date
shall not be a Business Day (notwithstanding any other provision of this Pledge
Agreement), any Remarketing of Senior Notes shall not settle on such date and
remarketed Senior Notes shall be settled on the next succeeding Business Day
with the same force and effect as if made on such Purchase Contract Settlement
Date, and without any adjustment of the Purchase Price.

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 Article 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 Article 2 hereof

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 Units.

or involve the Collateral Agent in personal liability and (ii) the Collateral
Agent shall be indemnified to its satisfaction as provided herein.  Nothing
contained in this Section
9.02 shall impair the right of the Collateral Agent in its discretion to

or the Securities Intermediary, be deemed to be conclusively proved and
established by a certificate signed by one of the Company’s officers, and
delivered to the Collateral Agent, the Custodial Agent or the Securities
Intermediary and such certificate, in the absence of gross negligence or bad
faith on the part of the Collateral Agent, the Custodial Agent or the Securities
Intermediary, shall be full warrant to the Collateral Agent, the Custodial Agent

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

at any time by giving notice thereof to the Company and the Purchase Contract
Agent as attorney-in-fact for the Holders of Units;






(ii)           the
Collateral Agent, the Custodial Agent and the Securities Intermediary may be
removed at any time by the Company; and






(ii)           
if the Collateral Agent, the Custodial Agent or 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 Collateral Agent, the Custodial Agent and the Securities
Intermediary may be removed by the Purchase Contract Agent, acting at the
direction of the Holders of Units.






The
Purchase Contract Agent shall promptly notify the Company of any removal of the
Collateral Agent, the Custodial Agent or the Securities Intermediary pursuant to
clause (iii) of this Section
9.10.  Upon any such resignation or removal, the Company shall have
the right to appoint a successor Collateral Agent, Custodial Agent or Securities
Intermediary, as the case may be, which shall not be an Affiliate of the
Purchase Contract Agent.  If no successor Collateral Agent, Custodial Agent
or Securities Intermediary shall have been so appointed and shall have accepted
such appointment within 30 days after the retiring Collateral Agent’s, Custodial
Agent’s or Securities Intermediary’s giving of notice of resignation or the
Company’s or the Purchase Contract Agent’s giving notice of such removal, then
the retiring or removed Collateral Agent, Custodial Agent or Securities
Intermediary may petition any court of competent jurisdiction, at the expense of
the Company, for the appointment of a successor Collateral Agent, Custodial
Agent or Securities Intermediary.  The Collateral Agent, the Custodial
Agent and the Securities Intermediary shall each be a bank or a national banking
association which has an office (or an agency office) in New York City with a
combined capital and surplus of at least $50,000,000.  Upon the acceptance
of any appointment as Collateral Agent, Custodial Agent or Securities
Intermediary hereunder by a successor Collateral Agent, Custodial Agent or
Securities Intermediary, as the case may be, such successor Collateral Agent,
Custodial Agent or Securities Intermediary, as the case may be, shall thereupon
succeed to and become vested with all the




20


rights,
powers, privileges and duties of the retiring Collateral Agent, Custodial Agent
or Securities Intermediary, as the case may be, and the retiring Collateral
Agent, Custodial Agent or Securities Intermediary, as the case may be, shall
take all appropriate action, subject to payment of any amounts then due and
payable to it hereunder, to transfer any money and property held by it hereunder
(including the Collateral) to such successor.  The retiring Collateral
Agent, Custodial Agent or Securities Intermediary shall, upon such succession,
be discharged from its duties and obligations as Collateral Agent, Custodial
Agent or Securities Intermediary hereunder.  After any retiring Collateral
Agent’s, Custodial Agent’s or Securities Intermediary’s resignation hereunder as
Collateral Agent, Custodial Agent or Securities Intermediary, the provisions of
this Article 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, Custodial Agent or
Securities Intermediary.  Any resignation or removal of the Collateral
Agent, Custodial Agent or Securities Intermediary hereunder, at a time when such
Person is acting as the Collateral Agent, Custodial Agent or Securities
Intermediary, shall be deemed for all purposes of this Agreement as the
simultaneous resignation or removal of the Collateral Agent, Securities
Intermediary or Custodial Agent, as the case may be.






(b)           Because
U.S. Bank National Association is serving as the Collateral Agent hereunder and
the Purchase Contract Agent under the Purchase Contract Agreement, if an event
of default (other than an event of default occurring as a result of a Failed
Final Remarketing) occurs hereunder or under the Purchase Contract Agreement,
U.S. Bank National Association will resign as the Collateral Agent, but continue
to act as the Purchase Contract Agent.  A successor Collateral Agent will
be appointed in accordance with the terms hereof.  If any such event of
default is cured or waived prior to the appointment of a successor Collateral
Agent, the duty of U.S. Bank National Association to resign in respect of such
event of default shall cease.




Section
9.11  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 9.11 shall be subject
to prior written consent of the Company, which consent shall not be unreasonably
withheld.




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




Section
9.13  Exculpation.   Anything
contained in this Agreement to the contrary notwithstanding, in no event shall
the Collateral Agent, the Custodial 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, but not limited to, lost profits, whether or
not the likelihood of such loss or damage was known to the Collateral Agent, the
Custodial Agent or the Securities Intermediary, or any of them and regardless of
the form of action.

and the Collateral Agent, as the case may be, the Company, when duly authorized
by a Board Resolution, the Purchase Contract Agent, the Collateral 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

respect:






(a)           change
the amount or type of Collateral underlying a Unit (except for the rights of
holders of Corporate Units to substitute the Treasury Securities for the Pledged

Applicable Ownership Interests (as specified in clause (i) of the definition of
such term) in the Treasury Portfolio, as applicable, for the Pledged Treasury
Securities), unless such change is not adverse to the Holders, does not impair
the right of the Holder of any Unit to receive distributions on the underlying
Collateral or otherwise adversely affect the Holder’s rights in or to such
Collateral;






(b)           otherwise
effect any action that would require the consent of the Holder of each
Outstanding Unit affected thereby pursuant to the Purchase Contract Agreement if

the Purchase Contract Agreement; or






(c)           reduce
the percentage of Purchase Contracts the consent of whose Holders is required
for the modification or amendment of the provisions of this
Agreement;






provided that if any
amendment or proposal referred to above would adversely affect only the
Corporate Units or only the Treasury Units, then only the affected class of
Holders 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, further, 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 (a) through (c) 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.

Amendments.   In executing any amendment permitted by this
Article, the Collateral Agent, the Custodial Agent, the Securities Intermediary
