    (a)           Upon
receipt by the Collateral Agent of written notice from the Company or the
Purchase Contract Agent that a Termination Event has occurred, the Collateral
Agent shall release all Collateral from the Pledge and shall promptly instruct
the Securities Intermediary to Transfer:

     

     

    (i)           any
Pledged Senior Notes or security entitlements with respect thereto or Pledged

such term) in the Treasury Portfolio, the Purchase Contract Agent shall dispose
of such interest for cash and deliver to such Holder cash in lieu of delivering
the Applicable Ownership Interests (as specified in clause (i) of the definition

    (b)           If

Pledged Applicable Ownership Interests, Pledged Treasury Securities and payments
by Holders (or the Permitted Investments of such payments) pursuant to Section 5.05 and Proceeds of

    (i)           use
its best efforts to obtain an opinion of a nationally recognized law firm to the
effect that, notwithstanding the Company being the debtor in such a bankruptcy
case, the Collateral Agent will not be prohibited from releasing or Transferring
the Collateral as provided in this Section 5.04 and shall deliver
or cause to be delivered such opinion to the Collateral Agent within ten days
after the occurrence of such Termination Event, and if (A) the Purchase Contract
Agent shall be unable to obtain such opinion within ten days after the
occurrence of such Termination Event or (B) the Collateral Agent shall continue,
after delivery of such opinion, to refuse to effectuate the release and Transfer
of all Pledged Senior Notes, Pledged Applicable Ownership Interests, Pledged
Treasury Securities and the payments by Holders (or the Permitted Investments of

City time) on the sixth Business Day immediately preceding the Purchase Contract
Settlement Date of the Purchase Price in lawful money of the United States by
certified or cashier’s check or wire transfer of immediately available funds

Agent shall:

     

     

    (i)           instruct
the Securities Intermediary promptly to invest any such Cash in Permitted
Investments;

     

     

    (ii)           instruct

case free and clear of the Pledge created hereby.

     

     

    The Company shall instruct the
Collateral Agent in writing as to the type of Permitted Investments in which any
such Cash shall be invested; provided, however, that if the Company fails to deliver
such written instructions by 10:30 a.m. (New York City time) on the day such
Cash is received by the Collateral Agent or to be reinvested by the Securities
Intermediary, the Collateral Agent shall instruct the Securities Intermediary to
invest such Cash in the Permitted Investments described in clause (6) of the
definition of Permitted Investments.  In no event shall the Collateral
Agent or Securities Intermediary be liable for the selection of Permitted
Investments or for investment losses incurred thereon.  The Collateral
Agent and Securities Intermediary shall have no liability with respect to losses
incurred as a result of the failure of the Company to provide timely written
investment direction.  Upon receipt of Proceeds upon the
maturity of the Permitted Investments on the Purchase Contract Settlement Date,
the Collateral Agent shall (A) instruct the Securities Intermediary to pay the
portion of such Proceeds and deliver any certified or cashier’s checks received,
in an aggregate amount equal to the Purchase Price, to the Company on the

(B) release any amounts in excess of the Purchase Price earned from such
Permitted Investments to the Purchase Contract Agent for distribution to such
Holder in accordance with the Purchase Contract Agreement.

     

     

    (b)           If
a Holder of Corporate Units (unless the Treasury Portfolio has replaced the
Senior Notes as a component of such Corporate Units) (i) fails to notify the
Purchase Contract Agent of its intention to make a Cash Settlement as provided
in Section 5.02(b)(i) of
the Purchase Contract Agreement or (ii) does notify the Purchase Contract Agent
of its intention to pay the Purchase Price in cash, but fails to make such
payment as required by Section
5.02(b)(ii) of the Purchase Contract Agreement, such Holder shall be
deemed to have consented to the disposition of such Holder’s Pledged Senior
Notes in accordance with Section 5.02(b)(iii) of the
Purchase Contract Agreement.

     

     

    (c)           As

Cash Settlement of Corporate Units, (ii) the amount of Cash that it has received
with respect to the Cash Settlement of Treasury Units and (iii) the amount of
Pledged Senior Notes to be remarketed in the Remarketing pursuant to Section 5.02(a) of the

Contract Settlement Date, the Collateral Agent shall deliver to the Purchase
Contract Agent a notice, stating (i) the amount of Cash that it has received
with respect to the Cash Settlement of Corporate Units, (ii) the amount of Cash
that it has received with respect to the Cash Settlement of Treasury Units and
(iii) the amount of Pledged Senior Notes with respect to which an automatic
deemed exercise of the Put Right has occurred pursuant to Section 5.02(a) of the
Purchase Contract Agreement.

     

    Section
5.06 Early Settlement and Cash
Merger Early Settlement.  Upon receipt by the Collateral Agent of a
notice from the Purchase Contract Agent that a Holder of Units has elected to
effect either (i) Early Settlement of its obligations under the Purchase
Contracts forming a part of such Units in accordance with the terms of the
Purchase Contracts and Section
5.07 of the Purchase Contract Agreement or (ii) Cash Merger Early
Settlement of its obligations under the Purchase Contracts forming a part of
such Units in accordance with the terms of the Purchase Contracts and Section 5.04(b)(ii) of the
Purchase Contract Agreement (which notice shall set forth the number of such
Purchase Contracts as to which such Holder has elected to effect Early

Agent has received from such Holder, and paid to the Company as confirmed in
writing by the Company, the related Purchase Price pursuant to the terms of the
Purchase Contracts and the Purchase Contract Agreement and that all conditions
to such Early Settlement or Cash Merger Early Settlement, as the case may be,
have been satisfied, then the Collateral Agent shall release from the Pledge,
(1) Pledged Senior Notes or the Pledged Applicable Ownership Interests in the
case of a Holder of Corporate Units or (2) Pledged Treasury Securities, in the

to which such Holder has elected to effect Early Settlement or Cash Merger Early
Settlement, and shall instruct the Securities Intermediary to Transfer all such
Pledged Applicable Ownership Interests or Pledged Senior Notes or Pledged
Treasury Securities, as the case may be, to the Purchase Contract Agent for
distribution to such Holder, in each case free and clear of the Pledge created
hereby.  A Holder of Treasury Units may settle early only in integral
multiples of 40 Treasury Units, and a Holder of Corporate Units, if the Treasury
Portfolio has replaced the Senior Notes as a component of such Corporate Units,
may settle early only in integral multiples of 4,000 Corporate
Units.

    Stock or
Preferred Stock, as applicable, to be issued under such Purchase Contracts from
the Proceeds of the Remarketing of the related Pledged Senior Notes.  In
the event of a Successful Remarketing, the Collateral Agent shall instruct the
Securities Intermediary to Transfer the related Pledged Senior Notes to the
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
Purchase Contract Agent, instruct the Securities Intermediary to remit a portion
of the Proceeds from such Remarketing equal to the aggregate principal amount of
such Pledged Senior Notes to satisfy in full such Holder’s obligations to pay
the Purchase Price to purchase the shares of Common Stock or Preferred Stock, as
applicable, under the related Purchase Contracts and to remit the balance of the
Proceeds from the Remarketing, if any, to the Purchase Contract Agent for
distribution to such Holder.

     

     

    Upon a
Failed Final Remarketing, each Holder of Corporate Units (unless the Treasury
Portfolio has replaced the Senior Notes represented by such Corporate Units)
that has not elected to make an effective Cash Settlement by notifying the
Purchase Contract Agent in the manner provided for in Section 5.02(c)(i) of the
Purchase Contract Agreement or does notify the Purchase Contract Agent as
provided in Section
5.02(c)(i) of the Purchase Contract Agreement of its intention to pay the
Purchase Price in cash, but fails to make such payment as required by Section 5.02(c)(ii) of the
Purchase Contract Agreement, shall be deemed to have exercised such Holder’s Put
Right with respect to the Senior Notes that are a component of Corporate Units
have elected to have a portion of the Proceeds of the Put Right set-off against
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
Right in excess of the aggregate Purchase Price for the shares of Common Stock
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.

     

     

    (b)           A
Holder of a Treasury Unit or a Corporate Unit (if the Treasury Portfolio has
replaced the Senior Notes as a component of such Corporate Unit) shall be deemed
to have elected to pay for the shares of Common Stock or Preferred Stock, as
applicable, to be issued under such Purchase Contracts from the Proceeds of the
related Pledged Treasury Securities or Pledged Applicable Ownership Interests,
as the case may be.  Promptly, after 11:00 a.m. (New York City time) on the
Business Day immediately prior to the Purchase Contract Settlement Date, the
Collateral Agent shall invest the Proceeds in the Permitted Investments set
forth in Clause (6) of the definition of Permitted Investments, unless prior to
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

    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
Contract Agent such proxies and other instruments in respect of such Pledged
Senior Notes (in form and substance satisfactory to the Collateral Agent) as are
prepared by the Company and delivered to the Purchase Contract Agent with
respect to the Pledged Senior Notes.

Collateral Agent, in the event the Collateral Agent is unable to make payments
to the Company on account of the applicable Pledged Applicable Ownership

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.

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

Trustee to remit the Redemption Price to the Securities Intermediary for credit

Special Event Redemption Date, by federal funds check or wire transfer of
immediately available funds.  Upon receipt of such funds, the Pledged

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

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.

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

with the same force and effect as if made on such Purchase Contract Settlement
Date, and without any adjustment of the Purchase Price.

Holder has the power to grant a security interest in and lien on the

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

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

notwithstanding.

business with the Purchase Contract Agent, any other Person interested herein
and any Holder of Units (and any of their respective subsidiaries or affiliates)
as if it were not acting as the Collateral Agent, the Custodial Agent or the
Securities Intermediary, as the case may be, and the Collateral Agent, the
Custodial Agent, the Securities Intermediary and their affiliates may accept
fees and other consideration from the Purchase Contract Agent and any Holder of
Units without having to account for the same to the Company; provided that each of the
Securities Intermediary, the Custodial Agent and the Collateral Agent covenants

expenses (including reasonable fees and expenses of counsel) and taxes (other
than those based upon, determined by or measured by the income of the Collateral
Agent, the Custodial Agent and Securities Intermediary) (collectively, “Losses” and individually, a
“Loss”) that may be
imposed on, incurred by, or asserted against, the Indemnitees or any of them for
following any instructions or other directions upon which either the Collateral
Agent, the Custodial Agent or the Securities Intermediary is entitled to rely
pursuant to the terms of this Agreement, provided that the Collateral
Agent, the Custodial Agent or the Securities Intermediary has not acted with
gross negligence or engaged in willful misconduct or bad faith with respect to
the specific Loss against which indemnification is sought; and

     

     

    (c)           in
addition to and not in limitation of paragraph (b) immediately above, indemnify
and hold the Indemnitees and each of them harmless from and against any and all
Losses that may be imposed on, incurred by or asserted against, the Indemnitees
or any of them in connection with or arising out of the Collateral Agent’s, the
Custodial Agent’s or the Securities Intermediary’s acceptance or performance of
its powers and duties under this Agreement, provided that the Collateral Agent,
the Custodial Agent or the Securities Intermediary has not acted with gross
negligence or engaged in willful misconduct or bad faith with respect to the
specific Loss against which indemnification is sought.

     

     

    The
provisions of this Section

Custodial Agent or Securities Intermediary and the termination of this
Agreement.

     

    Section
9.09 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, then at its sole option, each of the Collateral Agent, the
Custodial Agent and the Securities Intermediary shall be entitled, after prompt
notice to the Company and the Purchase Contract Agent, to

     

    
      
        
        

      

      
        19

        
          

        

      

      
        
        

      

    

     refuse
to comply with any and all claims, demands or instructions with respect to such
property or funds so long as such dispute or conflict shall continue, and the
Collateral Agent, the Custodial 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, the Custodial Agent and the Securities Intermediary shall
be entitled to refuse to act until either:

     

     

    (a)           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, the
Custodial Agent or the Securities Intermediary; or

     

     

    (b)           the
Collateral Agent, the Custodial 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, the Custodial 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, the Custodial Agent or the Securities
Intermediary may deem necessary.  Notwithstanding anything contained herein
to the contrary, none of the Collateral Agent, the Custodial Agent or 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
9.10 Resignation of Collateral
Agent, the Custodial Agent and Securities Intermediary.

     

     

    (a)           Subject
to the appointment and acceptance of a successor Collateral Agent, Custodial
Agent or Securities Intermediary as provided below:

     

     

    (i)           the
Collateral Agent, the Custodial Agent and the Securities Intermediary 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 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.

    (c)           add

    Section
10.02 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, including
without limitation the consent of the Holders obtained in connection with a
tender or an exchange offer, by Act of such Holders delivered to the Company,
the Purchase Contract Agent, the Custodial Agent, the Securities Intermediary
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
rights of the Holders in respect of the Units; provided, however, that no such
supplemental agreement shall, without the unanimous consent of the Holders of
each Outstanding Unit adversely affected thereby in any material
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
Senior Notes or the Pledged Applicable Ownership Interests, as the case may be,
or the rights of Holders of Treasury Units to substitute Senior Notes or the
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
such action were effected by a modification or amendment of the provisions of
the Purchase Contract Agreement; or

     

     

    (c)           reduce

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.

     

    Section

    CHANGES
TO THE GENERAL TERMS AND CONDITIONS

    OF
THE ORIGINAL SENIOR NOTES

     

    Section
2.01 Amendment of Section 1.02 of
Supplemental Indenture No. 1.  Supplemental Indenture No.
1 is hereby amended by deleting the definition of “Definitive Senior Notes” from
Section 1.02 thereof.

     

    Section
2.02 Amendment of Section 2.04 of
Supplemental Indenture No. 1.  Supplemental Indenture No.
1 is hereby amended by deleting Section 2.04 thereof in its entirety and
replacing it with the following:

     

     

    Section
2.04.        Global or Definitive Senior
Notes.  Senior Notes that are no longer a component of the Corporate
Units and are released from the Collateral Account (as defined
in the Pledge Agreement) may, at the Company’s option, either be issued (i) in
fully registered, global form, and initially evidenced by one or more
certificates issued to Cede & Co., as nominee of The Depository Trust
Company, or (ii) in certificated form.

     

    Section
2.03 Amendment of Section 2.05 of
Supplemental Indenture No. 1.  Supplemental Indenture No.
1 is hereby amended by deleting Section 2.05 thereof in its entirety and
replacing it with the following:

     

     

    Section
2.05.        Interest. 
(a)  The Senior Notes will bear interest initially at the rate of 5.1% per
year (the “Coupon Rate”)
from the original date of issuance through and including the earlier of (i) the
Maturity Date and (ii) the day immediately preceding any Reset Effective
Date.  In the event of a Successful Remarketing of the Senior Notes, the
Coupon Rate will be reset by the Remarketing Agent at the appropriate Reset Rate
with effect from the related Reset Effective Date, as set forth under Section 8.03.  If the
Coupon Rate is so reset, the Senior Notes will bear interest at the Reset Rate
from time to time in effect from the related Reset Effective Date until the
principal thereof and interest thereon is paid or duly made available for
payment and shall bear interest, to the extent permitted by law, compounded on
each Interest Payment Date, on any overdue principal and payment of interest at
the Coupon Rate through and including the day immediately preceding the Reset
Effective Date and at the Reset Rate from time to time in effect
thereafter.

     

     

    (b)      
Interest on the Senior Notes shall be payable quarterly in arrears on February
16, May 16, August 16 and November 16 of each year (each, an “Interest Payment Date”),
commencing November 16, 

     

    
      
        
        

      

      
        4

        
          

        

      

      
        
        

      

    

    2005, to
the Person in whose name such Senior Note, or any predecessor Senior Note, is
registered at the close of business on the Record Date for such Interest Payment
Date.  Interest on the Senior Notes shall accrue from October 7,
2005.

     

     

    Notwithstanding
the foregoing, in the event of a Successful Remarketing of the Senior Notes, the
Company may redetermine the Interest Payment Dates and the Senior Notes will
bear interest at the appropriate Reset Rate from time to time in effect from the
related Reset Effective Date payable either semi-annually or quarterly, as
determined by the Company.

     

     

    (c)      
If the Reset Rate is a fixed interest rate, the amount of interest payable for
any full quarterly or semi-annual period, as the case may be, will be computed
on the basis of a 360-day year consisting of twelve 30-day months.  The
amount of interest payable for any period shorter than a full quarterly or
semi-annual period, as the case may be, for which interest is computed will be
computed on the basis of a 30-day month and, for any period less than a month,
on the basis of the actual number of days elapsed per 30-day month.  In the
event that any scheduled Interest Payment Date falls on a day that is not a
Business Day, then payment of interest payable on such Interest Payment Date
will be made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay).

     

     

    (d)
      Notwithstanding any other provision of the
Indenture, in the event the Reset Rate is a floating interest rate, the Company
may elect (i) to modify the day count conventions set forth in this Section 2.05 and (ii) to modify the
definition of the term “Business Day” set forth in Section 1.02
herein.

     

    Section
2.04 Amendment of Article 8 of
Supplemental Indenture No. 1.  Supplemental Indenture No.
1 is hereby amended by deleting Article 8 thereof in its entirety and replacing
it with the following:

     

     

    Article
8

    REMARKETING

     

     

    Section
8.01.        Remarketing
Procedures.  (a)  Unless a Special Event Redemption, an Early
Settlement or a Cash Merger Early Settlement has occurred prior to the Initial
Remarketing Date, the Company shall engage the Remarketing Agent pursuant to the
Remarketing Agreement for the Remarketing of the Senior Notes.  The Company
will request, not later than seven nor more than 15 calendar days prior to the
Initial Remarketing Date, that the Trustee notify the Holders of 

     

    
      
        
        

      

      
        5

        
          

        

      

      
        
        

      

    

    Separate
Senior Notes, Corporate Units and Treasury Units of the procedures to be
followed in the Remarketings.

     

     

    (b)           Each
Holder of Separate Senior Notes may elect to have Separate Senior Notes held by
such Holder remarketed in all Remarketings.  A Holder making such an
election must, pursuant to the Pledge Agreement, notify the Custodial Agent and
deliver such Separate Senior Notes to the Custodial Agent on or prior to 5:00
p.m. (New York City time) on or prior to the seventh Business Day immediately
preceding the Initial Remarketing Date (but no earlier than the Interest Payment
Date immediately preceding the Initial Remarketing Date).  Any such notice
and delivery may not be conditioned upon the level at which the Reset Rate is
established in the Remarketing.  Any such notice and delivery may be
withdrawn on or prior to 5:00 p.m. (New York City time) on the seventh Business
Day immediately preceding the Initial Remarketing Date in accordance with the
provisions set forth in the Pledge Agreement.  Any such notice and delivery
not withdrawn by such time will be irrevocable with respect to all
Remarketings.  Pursuant to Section 5.07(c) of the Pledge
Agreement, by 12:00 noon, New York City time, on the Business Day immediately
preceding the Initial Remarketing Date, the Custodial Agent, based on the
notices and deliveries received by it prior to such time, shall notify the
Remarketing Agent of the principal amount of Separate Senior Notes to be
tendered for Remarketing and, upon a Successful Remarketing, shall cause such
Separate Senior Notes to be presented to the Remarketing Agent.  Under
Section 5.02 of the
Purchase Contract Agreement, Senior Notes that are components of Corporate Units
will be deemed tendered for Remarketing and will be remarketed in accordance
with the terms of the Remarketing Agreement.

     

     

    (c)           The
right of each Holder of Senior Notes that are included in Corporate Units to
have such Senior Notes, and each Holder of Separate Senior Notes to have any
Separate Senior Notes (together, the “Remarketed Senior Notes”),
remarketed and sold on any Remarketing Date shall be limited to the extent that
(i) the Remarketing Agent conducts a Remarketing pursuant to the terms of the
Remarketing 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 and (iv) the
purchaser or purchasers deliver the purchase price therefor to the Remarketing
Agent as and when required.

     

     

    (d)           Neither
the Trustee, the Company nor the Remarketing Agent shall be obligated in any
case to provide funds to make payment upon tender of Senior Notes for
remarketing.

    Section
8.02.        Remarketing. 
Unless a Special Event Redemption, an Early Settlement or a Cash Merger Early
Settlement has occurred prior to the Initial Remarketing Date, on the Initial
Remarketing Date, the Remarketing Agent shall, pursuant and subject to the terms
of the Remarketing Agreement, use commercially reasonable efforts to remarket
the Remarketed Senior Notes at a price (the “Remarketing Price”) equal to
100.00% of the aggregate principal amount of the Remarketed Senior
Notes.

     

     

    Section
8.03.        Reset Rate and Extended
Maturity Date.  (a)  In connection with each Remarketing, and
subject to Sections
8.03(b) and 8.03(c) below, the Remarketing
Agent shall determine, in consultation with the Company, the Reset Rate (with
the fixed interest rate or, in the case of a floating interest rate, the Reset
Spread rounded to the nearest one-thousandth (0.001) of one percent per annum)
that the Remarketed Senior Notes should bear in order to have an aggregate
market value equal to the Remarketing Price and that in the sole discretion of
the Remarketing Agent will enable it to remarket all of the Remarketed Senior
Notes at the Remarketing Price in such Remarketing.

     

     

    (b)           Anything
herein to the contrary notwithstanding, the Remarketing Agent shall have no
obligation to determine whether there is any limitation under applicable law on
the Reset Rate or, if there is any such limitation, the maximum permissible
Reset Rate on the Senior Notes and shall rely solely upon written notice from
the Company (which the Company agrees to provide prior to the eighth Business
Day before the Initial Remarketing Date) as to whether or not there is any such
limitation in any applicable jurisdiction.

     

     

    (c)           In
connection with each Remarketing, the Remarketing Agent, in consultation with
the Company, may extend the Maturity Date to a date selected by the Company that
is two or three years from the date on which the Reset Rate is set.  Such
extended maturity date (the “Extended Maturity Date”), if
any, will be specified in the Remarketing announcement and will become effective
on the Reset Effective Date.

     

     

    (d)           In
connection with each Remarketing, the Company may also elect to add any
additional financial covenants as the Company may determine.  Such an
election would take effect, upon a Successful Remarketing, on the Reset
Effective Date.  In addition, as provided in Section 2.05(b) herein, upon a
Successful Remarketing, the Interest Payment Dates may be redetermined to
provide for payment of interest semi-annually instead of
quarterly.  Furthermore, as provided in Section 2.05(d) herein, upon a
Successful Remarketing at a floating interest rate Reset Rate, the business day
and day count conventions set forth in 

     

    
      
        
        

      

      
        7

        
          

        

      

      
        
        

      

    

    Section 2.05 herein and the
definition of “Business Day” set forth in Section 1.02 herein may be
modified.

     

     

    (e)           In
the event of a Failed Final Remarketing or if no Senior Notes are included in
Corporate Units and none of the Holders of the Separate Senior Notes elect to
have their Senior Notes remarketed in any Remarketing, the applicable interest
rate on the Senior Notes will not be reset and will continue to be the Coupon
Rate and the Maturity Date will not be extended.

     

     

    (f)           In
the event of a Successful Remarketing, as of the Reset Effective Date, the
Coupon Rate shall be reset at the Reset Rate as determined by the Remarketing
Agent under the Remarketing Agreement and the Maturity Date, if extended, will
be extended to the Extended Maturity Date.

     

     

    (g)           The
Company, at its option, may elect for the Reset Rate to be either a fixed
interest rate (as determined by the Remarketing Agent) or a floating interest
rate equal to the sum of the Reset Spread (as determined by the Remarketing
Agent) and the Base Rate (as determined by the Company).  The Amended
Senior Notes may have such terms in addition to or in lieu of any one or more of
the terms established pursuant to any of the provisions of this Supplemental
Indenture No. 2 and may be in such form, in any case, as the Company may
determine and as shall be set forth in an indenture supplemental to the
Indenture,  as supplemented and amended hereby; and the Trustee is
hereby authorized and directed to join with the Company in the execution and
delivery of any such supplemental indenture, such supplemental indenture, if
any, to be effective as the Reset Effective Date.

     

     

     

    Section
8.04.        Failed
Remarketing.  (a)  If, by 4:00 p.m. (New York City time) on any
Remarketing Date, the Remarketing Agent is unable to remarket all of the
Remarketed Senior Notes at the Remarketing Price, pursuant to the terms and
conditions hereof, a Failed Remarketing shall be deemed to have occurred, and
the Remarketing Agent shall so advise by telephone the Purchase Contract Agent
and the Company.  Whether or not there has been a Failed Remarketing will
be determined in the sole reasonable discretion of the Remarketing Agent. 
Promptly following any Failed Final Remarketing, the Custodial Agent shall
return the Separate Senior Notes to the appropriate Holders.

     

     

    (b)           The
Company shall cause a notice of a Failed Final Remarketing to be posted on the
Company’s website by the first Business Day following such Failed Final
Remarketing.

    Section
8.05.        Put Right. 
(a)  Subject to paragraph (b) hereof, if there has not been a Successful
Remarketing prior to the Purchase Contract Settlement Date, Holders of Separate
Senior Notes and Holders of Senior Notes that are a component of Corporate Units
will, subject to this Section
8.05, have the right (the “Put Right”) to require the
Company to purchase their Senior Notes, on the Purchase Contract Settlement
Date, at a price per Senior Note equal to $1,000.00 plus accrued and unpaid
interest to but excluding the Purchase Contract Settlement Date (the “Put Price”).

     

     

    (b)           The
Put Right of Holders of Senior Notes that are part of Corporate Units will be
automatically exercised unless such Holders (1) prior to 5:00 p.m., New York
City time, on the second Business Day immediately preceding the Purchase
Contract Settlement Date, provide written notice to the Purchase Contract Agent
of their intention to settle the related Purchase Contract with separate cash,

the Proceeds of the Put Right of such Senior Notes equal to the Purchase Price
