in this Section.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any manner which the Agent deems
sufficient.

         (c) The ownership of Equity Security Units or Stripped Units shall be
proved by the Equity Security Units Register or the Stripped Units Register, as
the case may be.

         (d) Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Certificate shall bind every future
Holder of the same Certificate and the Holder of every Certificate issued upon
the registration of transfer thereof or in exchange therefor or in lieu thereof
in respect of anything done, omitted or suffered to be done by the Agent or the
Company in reliance thereon, whether or not notation of such action is made upon

         (e) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Units entitled to give, make or take any
request, demand, authorization, direction, notice, consent, waiver or other
action provided or permitted by this Agreement to be given, made or taken by
Holders of Equity Security Units and Stripped Units. If any record date is set
pursuant to this paragraph, the Holders of the Outstanding Units on such record
date, and no other Holders, shall be entitled to take the relevant action with
respect to the Equity Security Units or the Stripped Units, as the case may be,
whether or not such Holders remain Holders after such record date; provided that
no such action shall be effective hereunder unless taken on or prior to the
applicable Expiration Date by Holders of the requisite number of Outstanding
Units on such record date. Nothing contained in this paragraph shall be
construed to prevent the Company from setting a new record date for any action
for which a record date has previously been set pursuant to this paragraph
(whereupon the record date previously set shall automatically and with no action
by any Person be cancelled and of no effect), and nothing contained in this
paragraph shall be construed to render ineffective any action taken by Holders
of the requisite number of Outstanding Units on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Company,
at its own expense, shall cause notice of such record date, the proposed action
by Holders and the applicable Expiration Date to be given to the Agent in
writing and to each Holder of Equity Security Units and Stripped Units in the
manner set forth in Section 1.6.

         (f) With respect to any record date set pursuant to this Section, the
Company may designate any date as the "Expiration Date" and from time to time
may change the Expiration Date to any earlier or later day; provided that no
such change shall be effective unless notice of the proposed new Expiration Date
is given to the Agent in writing, and to each Holder of Equity Security Units
and Stripped Units in the manner set forth in Section 1.6, on or prior to the
existing Expiration Date. If an Expiration Date is not designated with respect
to any record date set pursuant to this Section, the Company shall be deemed to
have initially designated the 180th day after such record date as the Expiration
Date with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date
shall be later than the 180th day after the applicable record date.

         Section 1.6 Notice to Holders; Waiver.

         (a) Where this Agreement provides for notice to Holders of any event,
such notice shall be sufficiently given (unless otherwise herein expressly
provided) if in writing and mailed, first-class postage prepaid, to each Holder
affected by such event, at its address as it appears in the applicable Register,
not later than the latest date, and not earlier than the earliest date,
prescribed for the giving of such notice. In any case where notice to Holders is
given by mail, neither the failure to mail such notice nor any defect in any
notice so mailed to any particular Holder shall affect the sufficiency of such
notice with respect to other Holders. Where this Agreement provides for notice
in any manner, such notice may be waived in writing by the Person entitled to
receive such notice, either before or after the event, and such waiver shall be
the equivalent of such notice. Waivers of notice by Holders shall be filed with
the Agent, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

         (b) In case by reason of the suspension of regular mail service or by
reason of any other cause it shall be impracticable to give such notice by mail,
then such notification as shall be made with the approval of the Agent shall
constitute a sufficient notification for every purpose hereunder.

         Section 1.7 Effect of Headings and Table of Contents.

         The Article and Section headings herein and the Table of Contents are
for convenience only and shall not affect the construction hereof.

         Section 1.9 Separability Clause.

         In case any provision in this Agreement or in the Equity Security Units

legality and enforceability of the remaining provisions hereof and thereof shall
not in any way be affected or impaired thereby.

claim under this Agreement. The Holders from time to time shall be beneficiaries

         (a) This Agreement, the Equity Security Units and Stripped Units shall
be governed by, and construed in accordance with, the laws of the State of New

acceptance thereof, the Company and the Agent each submit to the jurisdiction of
the courts of the State of New York and the courts of the United States of

Security Unit or a Stripped Unit, by its acceptance thereof, the Company and the
Agent each waive any objection that any of them may have to the venue of any
suit, action or proceeding with respect to this Agreement or the transactions
contemplated hereby in the courts of the State of New York or the courts of the
United States of America, in each case located in the Borough of Manhattan, City
of New York and State of New York, or that such suit, action or proceeding
brought in the courts of the State of New York or the courts of the United
States of America, in each case located in the Borough of Manhattan, City of New
York and State of New York, was brought in an inconvenient court and agrees not
to plead or claim the same.

         (c) Each Holder of an Equity Security Unit or a Stripped Unit, by its
acceptance thereof, the Company and the Agent each acknowledge and agree that
any controversy which may arise under this Agreement is likely to involve
complicated and difficult issues, and therefore irrevocably and unconditionally
waive any right it may have to a trial by jury in respect of any litigation
directly or indirectly arising out of relating to this Agreement or the
transactions contemplated hereby.

         Section 3.1 Title and Terms; Denominations.

         (a) The aggregate number of Equity Security Units and Stripped Units,
if any, evidenced by Certificates authenticated, executed on behalf of the
Holders and delivered hereunder is limited to 10,000,000 (up to 11,500,000 if

of, in exchange for, or in lieu of other Certificates pursuant to Section 3.4,
3.5, 3.10, 3.13, 3.14, 5.9, 5.10 or 8.5.

         (b) The Certificates shall be issuable only in registered form and only

         Section 3.2 Rights and Obligations Evidenced by the Certificates.

         (a) Each Equity Security Units Certificate shall evidence the number of
Equity Security Units specified therein, with each such Equity Security Units
Certificate representing the ownership by the Holder thereof of a beneficial
interest in a Note, the Treasury Consideration or the Applicable Ownership
Interest in the Treasury Portfolio, as the case may be, subject to the Pledge of
such Note, such Treasury Consideration or such Applicable Ownership Interest in
the Treasury Portfolio, as the case may be, by such Holder pursuant to the
Pledge Agreement, and the rights and obligations of the Holder thereof and the
Company under one Purchase Contract. The Agent, as attorney-in-fact for, and on
behalf of, the Holder of each Equity Security Unit shall pledge, pursuant to the
Pledge Agreement, the Note, the Treasury Consideration or the Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, forming a part
of such Equity Security Units, to the Collateral Agent and grant to the
Collateral Agent a security interest in the right, title, and interest of such
Holder in such Note, such Treasury Consideration or such Applicable Ownership
Interest in the Treasury Portfolio, as the case may be, for the benefit of the
Company, to secure the obligation of the Holder under each Purchase Contract to
purchase the Common Stock of the Company. Prior to the purchase of shares of
Common Stock under each Purchase Contract, such Purchase Contracts shall not
entitle the Holders of Equity Security Units Certificates to any of the rights
of a holder of shares of Common Stock, including, without limitation, the right
to vote or receive any dividends or other payments or to consent or to receive
notice as stockholders in respect of the meetings of stockholders or for the
election of directors of the Company or for any other matter, or any other

rights and obligations of the Holder thereof and the Company under one Purchase
Contract. The Agent, as attorney-in-fact for, and on behalf of, the Holder of
each Stripped Unit shall pledge,

                                       20
<PAGE>

pursuant to the Pledge Agreement, the Treasury Security, forming a part of such
Stripped Unit, to the Collateral Agent and grant to the Collateral Agent a
security interest in the right, title and interest of such Holder in such
Treasury Security for the benefit of the Company, to secure the obligation of
the Holder under each Purchase Contract to purchase shares of Common Stock
pursuant to this Agreement and the related Purchase Contract. Prior to the
purchase of shares of Common Stock under each Purchase Contract, such Purchase
Contracts shall not entitle the Holders of Stripped Units Certificates to any of
the rights of a holder of shares of Common Stock, including, without limitation,
the right to vote or receive any dividends or other payments or to consent or to
receive notice as stockholders in respect of the meetings of stockholders or for
the election of directors of the Company or for any other matter, or any other
rights whatsoever as stockholders of the Company.

         Section 3.3 Execution, Authentication, Delivery and Dating.

         (a) Subject to the provisions of Sections 3.1, 3.13 and 3.14, upon the
execution and delivery of this Agreement, and at any time and from time to time
thereafter, the Company may deliver Certificates executed by the Company to the
Agent for authentication, execution on behalf of the Holders and delivery,
together with its Issuer Order for authentication of such Certificates, and the
Agent in accordance with such Issuer Order shall authenticate, execute on behalf
of the Holders and deliver such Certificates.

         (b) The Certificates shall be executed on behalf of the Company by the
Chairman of the Board, the Chief Executive Officer, the President, any Vice
President or any other authorized officer of the Company or a person duly
authorized by any of them and delivered to the Agent. The signature of any of
these officers on the Certificates may be manual or by facsimile.

         (c) Certificates bearing the manual or facsimile signatures of
individuals who were at any time the proper officers of the Company shall bind
the Company, notwithstanding that such individuals or any of them have ceased to
hold such offices prior to the authentication and delivery of such Certificates
or did not hold such offices at the date of such Certificates.

         (d) No Purchase Contract evidenced by a Certificate shall be valid
until such Certificate has been executed on behalf of the Holder by the manual
signature of an authorized officer of the Agent, as such Holder's
attorney-in-fact. Such signature by an authorized officer of the Agent shall be
conclusive evidence that the Holder of such Certificate has entered into the
Purchase Contracts evidenced by such Certificate.

         (e) Each Certificate shall be dated the date of its authentication.

         (f) No Certificate shall be entitled to any benefit under this
Agreement or be valid or obligatory for any purpose unless there appears on such
Certificate a certificate of authentication substantially in the form provided
for herein executed by an authorized officer of the Agent by manual signature,
and such certificate upon any Certificate shall be conclusive evidence, and the
only evidence, that such Certificate has been duly authenticated and delivered
hereunder.

         Section 3.4 Temporary Certificates.

         (a) Pending the preparation of definitive Certificates, the Company
shall execute and deliver to the Agent, and the Agent shall authenticate,
execute on behalf of the Holders, and deliver, in lieu of such definitive
Certificates, temporary Certificates which are in substantially the form set
forth in Exhibit A or Exhibit B hereto, as the case may be, with such letters,
numbers or other marks of identification or designation and such legends or
endorsements printed, lithographed or engraved thereon as may be required by the
rules of any securities exchange on which the Equity Security Units or Stripped
Units, as the case may be, are listed, or as may, consistent herewith, be
determined by the officers of the Company executing such Certificates, as
evidenced by their execution of the Certificates.

         (b) If temporary Certificates are issued, the Company will cause
definitive Certificates to be prepared without unreasonable delay. After the
preparation of definitive Certificates, the temporary Certificates shall be
exchangeable for definitive Certificates upon surrender of the temporary
Certificates at the Corporate Trust Office, at the expense of the Company and
without charge to the Holder. Upon surrender for cancellation of any one or more
temporary Certificates, the Company shall execute and deliver to the Agent, and
the Agent shall authenticate, execute on behalf of the Holder, and deliver in
exchange therefor, one or more definitive Certificates of like tenor and
denominations and evidencing a like number of Equity Security Units or Stripped
Units, as the case may be, as the temporary Certificate or Certificates so
surrendered. Until so exchanged, the temporary Certificates shall in all
respects evidence the same benefits and the same obligations with respect to the
Equity Security Units or Stripped Units, as the case may be, evidenced thereby
as definitive Certificates.

         Section 3.5 Registration; Registration of Transfer and Exchange.

         (a) The Agent shall keep at the Corporate Trust Office a register (the
"Equity Security Units Register") in which, subject to such reasonable
regulations as it may prescribe, the Agent shall provide for the registration of
Equity Security Units Certificates and of transfers of Equity Security Units
Certificates (the Agent, in such capacity, the "Equity Security Units
Registrar") and a register (the "Stripped Units Register") in which, subject to
such reasonable regulations as it may prescribe, the Agent shall provide for the
registration of the Stripped Units Certificates and transfers of Stripped Units
Certificates (the Agent, in such capacity, the "Stripped Units Registrar").

         (b) Upon surrender for registration of transfer of any Certificate at
the Corporate Trust Office, the Company shall execute and deliver to the Agent,
and the Agent shall authenticate, execute on behalf of the designated transferee
or transferees, and deliver, in the name of the designated transferee or
transferees, one or more new Certificates of like tenor and denominations, and
evidencing a like number of Equity Security Units or Stripped Units, as the case
may be.

         (c) At the option of the Holder, Certificates may be exchanged for
other Certificates, evidencing a like aggregate number of Equity Security Units
or Stripped Units, as the case may be, upon surrender of the Certificates to be
exchanged at the Corporate Trust Office. Whenever any Certificates are so
surrendered for exchange, the Company shall execute and deliver to the Agent,

                                       22
<PAGE>

and the Agent shall authenticate, execute on behalf of the Holder, and deliver
the Certificates which the Holder making the exchange is entitled to receive.

         (d) All Certificates issued upon any registration of transfer or
exchange of a Certificate shall evidence the ownership of the same number of
Equity Security Units or Stripped Units, as the case may be, and be entitled to
the same benefits and subject to the same obligations, under this Agreement as
the Equity Security Units or Stripped Units, as the case may be, evidenced by
the Certificate surrendered upon such registration of transfer or exchange.

         (e) Every Certificate presented or surrendered for registration of
transfer or for exchange shall (if so required by the Agent) be duly endorsed,
or be accompanied by a written instrument of transfer in form satisfactory to
the Company and the Agent duly executed, by the Holder thereof or its attorney
duly authorized in writing.

         (f) No service charge shall be made for any registration of transfer or
exchange of a Certificate, but the Company and the Agent may require payment
from the Holder of a sum sufficient to cover any tax or other governmental
charge that may be imposed in connection with any registration of transfer or
exchange of Certificates, other than any exchanges pursuant to Sections 3.4,
3.6, 3.9 and 8.5 not involving any transfer.

         (g) Notwithstanding the foregoing, the Company shall not be obligated
to execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder and deliver any Certificate
presented or surrendered for registration of transfer or for exchange on or
after the Business Day immediately preceding the earlier of the Stock Purchase
Date and the Termination Date. In lieu of delivery of a new Certificate, upon
satisfaction of the applicable conditions specified above in this Section and
receipt of appropriate registration or transfer instructions from such Holder,
the Agent shall,

                  (i) if the Stock Purchase Date has occurred, deliver the
         shares of Common Stock issuable in respect of the Purchase Contracts
         forming a part of the Equity Security Units or Stripped Units, as the
         case may be, evidenced by such Certificate,

                  (ii) in the case of Equity Security Units, if a Termination
         Event shall have occurred prior to the Stock Purchase Date, transfer
         the Notes, the Treasury Consideration or the Applicable Ownership
         Interests in the Treasury Portfolio, as applicable, relating to such
         Equity Security Units, or

                  (iii) in the case of Stripped Units, if a Termination Event
         shall have occurred prior to the Stock Purchase Date, transfer the
         Treasury Securities relating to such Stripped Units,

in each case subject to the applicable conditions and in accordance with the
applicable provisions of Article V.

         Section 3.6 Book-Entry Interests.

         The Certificates on original issuance will be issued in the form of one

the Company. Each Global Certificate shall initially be registered in the
applicable Register in the name of Cede & Co., the nominee of the Depositary,
and no Beneficial Owner will receive a definitive Certificate representing such
Beneficial Owner's interest in such Global Certificate, except as provided in
Section 3.9. The Agent shall enter into an agreement with the Depositary if so
requested by the Company and if required by the Depositary. Unless and until
definitive, fully registered Certificates have been issued to Beneficial Owners
pursuant to Section 3.9:

                  (a) the provisions of this Section 3.6 shall be in full force
         and effect;

                  (b) the Company shall be entitled to deal with the Clearing
         Agency for all purposes of this Agreement (including receiving
         approvals, votes or consents hereunder) as the Holder of the Equity
         Security Units and Stripped Units and the sole holder of the Global
         Certificate(s) and shall have no obligation to the Beneficial Owners;

                  (c) to the extent that the provisions of this Section 3.6
         conflict with any other provisions of this Agreement, the provisions of
         this Section 3.6 shall control; and

                  (d) the rights of the Beneficial Owners shall be exercised
         only through the Clearing Agency and shall be limited to those
         established by law and agreements between such Beneficial Owners and
         the Clearing Agency and/or the Clearing Agency Participants. The
         Clearing Agency will make book-entry transfers among Clearing Agency
         Participants.

         Section 3.7 Notices to Holders.

         Whenever a notice or other communication to the Holders is required to
be given under this Agreement, the Company or the Company's agent shall give
such notices and communications to the Holders and, with respect to any Equity
Security Units or Stripped Units registered in the name of a Clearing Agency or
the nominee of a Clearing Agency, the Company or the Company's agent shall,
except as set forth herein, have no obligations to the Beneficial Owners.

         Section 3.8 Appointment of Successor Clearing Agency.

         If any Clearing Agency elects to discontinue its services as securities
depositary with respect to the Equity Security Units and Stripped Units or
ceases to be eligible as a "clearing agency" under the Exchange Act, the Company
may, in its sole discretion, appoint a successor Clearing Agency with respect to
the Equity Security Units and Stripped Units.

         Section 3.9 Definitive Certificates.

         If:

                  (i) a Clearing Agency elects to discontinue its services as
         securities depositary with respect to the Equity Security Units and
         Stripped Units or ceases to be eligible as a "clearing agency" under
         the Exchange Act and a successor Clearing Agency is not appointed
         within 90 days after such discontinuance pursuant to Section 3.8,

                  (ii) the Company elects to terminate the book-entry system
         through the Clearing Agency with respect to the Equity Security Units
         and Stripped Units, or

                                       24
<PAGE>

                  (iii) there shall have occurred and be continuing a default by
         the Company in respect of its obligations under one or more Purchase
         Contracts, this Agreement, the Indenture, the Notes, the Equity
         Security Units, the Stripped Units, the Pledge Agreement or any other
         principal agreements or instruments executed in connection with the
         offering of Equity Security Units,

then upon surrender of the Global Certificates representing the Book-Entry
Interests with respect to the Equity Security Units and Stripped Units by the
Clearing Agency, accompanied by registration instructions, the Company shall
cause definitive Certificates to be delivered to Clearing Agency Participants in
accordance with the instructions of the Clearing Agency. The Company and the
Agent shall not be liable for any delay in delivery of such instructions and may
conclusively rely on and shall be protected in relying on such instructions.

         Section 3.10 Mutilated, Destroyed, Lost and Stolen Certificates.

         (a) If any mutilated Certificate is surrendered to the Agent, the
Company shall execute and deliver to the Agent, and the Agent shall
authenticate, execute on behalf of the Holder, and deliver in exchange therefor,
a new Certificate at the cost of the Holder, evidencing the same number of
Equity Security Units or Stripped Units, as the case may be, and bearing a
Certificate number not contemporaneously outstanding.

         (b) If there shall be delivered to the Company and the Agent (i)
evidence to their satisfaction of the destruction, loss or theft of any
Certificate, and (ii) such security or indemnity at the cost of the Holder as
may be required by them to hold each of them and any agent of any of them
harmless, then, in the absence of notice to the Company or the Agent that such
Certificate has been acquired by a bona fide purchaser, the Company shall
execute and deliver to the Agent, and the Agent shall authenticate, execute on
behalf of the Holder, and deliver to the Holder, in lieu of any such destroyed,
lost or stolen Certificate, a new Certificate, evidencing the same number of
Equity Security Units or Stripped Units, as the case may be, and bearing a
Certificate number not contemporaneously outstanding.

         (c) Notwithstanding the foregoing, the Company shall not be obligated
to execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder, and deliver to the Holder, a
Certificate on or after the Business Day immediately preceding the earlier of
the Stock Purchase Date and the Termination Date. In lieu of delivery of a new
Certificate, upon satisfaction of the applicable conditions specified above in
this Section and receipt of appropriate registration or transfer instructions
from such Holder, the Agent shall (i) if the Stock Purchase Date has occurred,
deliver the shares of Common Stock issuable in respect of the Purchase Contracts
forming a part of the Equity Security Units or Stripped Units evidenced by such
Certificate, or (ii) if a Termination Event shall have occurred prior to the
Stock Purchase Date, transfer the Notes, the Treasury Consideration or the
Applicable Ownership Interests in the Treasury Portfolio or the Treasury
Securities, as the case may be, evidenced thereby, in each case subject to the
applicable conditions and in accordance with the applicable provisions of
Article V.

         (d) Upon the issuance of any new Certificate under this Section, the
Company and the Agent may require the payment by the Holder of a sum sufficient
to cover any tax or other

                                       25
<PAGE>

governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Agent) connected therewith.

         (e) Every new Certificate issued pursuant to this Section in lieu of
any destroyed, lost or stolen Certificate shall constitute an original
contractual obligation of the Company and of the Holder in respect of the Equity
Security Units or Stripped Units, as the case may be, evidenced thereby, whether
or not the destroyed, lost or stolen Certificate (and the Equity Security Units
and Stripped Units evidenced thereby) shall be at any time enforceable by
anyone, and shall be entitled to all the benefits and be subject to all the
obligations of this Agreement equally and proportionately with any and all other
Certificates delivered hereunder.

         (f) The provisions of this Section are exclusive and shall preclude (to
the extent lawful) all other rights and remedies with respect to the replacement
or payment of mutilated, destroyed, lost or stolen Certificates.

         Section 3.11 Persons Deemed Owners.

         (a) Prior to due presentment of a Certificate for registration of
transfer, the Company and the Agent, and any agent of the Company or the Agent,
may treat the Person in whose name such Certificate is registered as the owner
of the Equity Security Units or Stripped Units, as the case may be, evidenced
thereby, for the purpose of receiving interest payments on the Notes (in the
case of Equity Security Units), receiving payment of Contract Adjustment
Payments, performance of the Purchase Contracts and for all other purposes
whatsoever (subject to Section 4.1(a) and 5.2(a)), whether or not any such
payments shall be overdue and notwithstanding any notice to the contrary, and
neither the Company nor the Agent, nor any agent of the Company or the Agent,
shall be affected by notice to the contrary.

         (b) Notwithstanding the foregoing, with respect to any Global
Certificate, nothing contained herein shall prevent the Company, the Agent or
any agent of the Company or the Agent from giving effect to any written
certification, proxy or other authorization furnished by any Clearing Agency (or
its nominee), as a Holder, with respect to such Global Certificate or impair, as
between such Clearing Agency and owners of beneficial interests in such Global
Certificate, the operation of customary practices governing the exercise of
rights of such Clearing Agency (or its nominee) as Holder of such Global
Certificate. None of the Company, the Agent, or any agent of the Company or the
Agent will have any responsibility or liability for any aspect of the records
relating to or payments made on account of beneficial ownership interests in a
Global Certificate or maintaining, supervising or reviewing any records relating
to such beneficial ownership interests.

         Section 3.12 Cancellation.

         (a) All Certificates surrendered (i) for delivery of shares of Common
Stock on or after any Settlement Date; (ii) upon the transfer of Notes, the
Treasury Consideration or the Applicable Ownership Interests in the Treasury
Portfolio or the Treasury Securities, as the case may be, after the occurrence
of a Termination Event; or (iii) upon the registration of a transfer or exchange
of Equity Security Units or Stripped Units, as the case may be, shall, if
surrendered to any Person other than the Agent, be delivered to the Agent and,
if not already cancelled, shall be promptly

                                       26

cancelled by it. The Company may at any time deliver to the Agent for
cancellation any Certificates previously authenticated, executed and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Certificates so delivered shall, upon Issuer Order, be promptly cancelled by the
Agent. No Certificates shall be authenticated, executed on behalf of the Holder
and delivered in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as expressly permitted by this Agreement. All
cancelled Certificates held by the Agent shall be disposed of by the Agent in
accordance with its customary procedures.

         (b) If the Company or any Affiliate of the Company shall acquire any
Certificate, such acquisition shall not operate as a cancellation of such
Certificate unless and until such Certificate is cancelled or delivered to the
Agent for cancellation.

         Section 3.13 Creation of Stripped Units.

         (a) Unless a successful remarketing or a Tax Event Redemption has

Purchase Contracts in respect of the Equity Security Units held by such Holder
by substituting for such Pledged Notes Treasury Securities that will pay, on the
Stock Purchase Date, an amount equal to the aggregate principal amount of such
Notes (a "Collateral Substitution") by (1) depositing with the Collateral Agent
Treasury Securities having an aggregate principal amount equal to the aggregate
Stated Amount of such Equity Security Units, and (2) instructing the Agent, in
its capacity as custodian for the Depositary, to decrease the number of Equity
Security Units evidenced by the Global Equity Security Units Certificate(s), by
a notice substantially in the form of Exhibit D hereto, and notifying the Agent
that the Holder has transferred the relevant amount of Treasury Securities to
the Collateral Agent and requesting that the Agent instruct the Collateral Agent
to release the Pledged Notes underlying such Equity Security Units (or, if the
Equity Security Units are held in certificated form, transferring the related
Equity Security Units to the Agent accompanied by a notice to the Agent,
substantially in the form of Exhibit D hereto), whereupon the Agent shall
promptly give such instruction to the Collateral Agent, substantially in the
form of Exhibit C hereto. Upon receipt of the Treasury Securities described in
clause (1) above and the instruction described in clause (2) above, in
accordance with the terms of the Pledge Agreement, the Collateral Agent will
release to the Agent, on behalf of the Holder, such Pledged Notes from the
Pledge, free and clear of the Company's security interest therein, and upon
receipt thereof the Agent shall promptly:

                  (i) decrease the number of Equity Security Units evidenced by
         the Global Equity Security Units Certificate(s) (or, if the Equity
         Security Units are held in certificated form, cancel the related Equity
         Security Units Certificates);

                  (ii) transfer the Pledged Notes to the Holder; and

                                       27
<PAGE>

                  (iii) increase the number of Stripped Units evidenced by the
         Global Stripped Units Certificate(s) (or, if the Stripped Units are
         held in certificated form, authenticate, execute on behalf of such
         Holder and deliver to such Holder a Stripped Units Certificate executed
         by the Company in accordance with Section 3.3 evidencing the same
         number of Purchase Contracts as were evidenced by the cancelled Equity
         Security Units).

         (b) Holders who elect to withdraw the Pledged Notes from the related
Purchase Contracts by substituting Treasury Securities for such Pledged Notes
shall be responsible for any fees or expenses payable to the Collateral Agent
for its services as Collateral Agent in respect of the substitution, and the
Company shall not be responsible for any such fees or expenses.

         (c) Holders may make Collateral Substitutions only in integral
multiples of 20 Equity Security Units.

         (d) In the event a Holder making a Collateral Substitution pursuant to
this Section 3.13 fails to effect a book-entry transfer of the Equity Security
Units or fails to deliver an Equity Security Units Certificate to the Agent
after depositing Treasury Securities with the Collateral Agent, the Pledged
Notes constituting a part of such Equity Security Units, and any distributions
on such Pledged Notes shall be held in the name of the Agent or its nominee in
trust for the benefit of such Holder, until such Equity Security Units are so
transferred or the Equity Security Units Certificate is so delivered, as the
case may be, or, with respect to an Equity Security Units Certificate, such
Holder provides evidence satisfactory to the Company and the Agent that such
Equity Security Units Certificate has been destroyed, lost or stolen, together
with any indemnity that may be required by the Agent and the Company.

         (e) Except as described in this Section 3.13, for so long as the
Purchase Contract underlying an Equity Security Unit remains in effect, the
rights and obligations of the Holder of such Equity Security Unit in respect of
the Note, the Treasury Consideration or the Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, and the Purchase Contract comprising
such Equity Security Unit may be acquired, and may be transferred and exchanged,
only as an Equity Security Unit.

         Section 3.14 Recreation of Equity Security Units.

         (a) Unless a successful remarketing or a Tax Event Redemption has
occurred, at any time from and after the date of this Agreement (A) other than
during the period that commences at 5:00 p.m., New York City time, on May 5,
2005 and ends at 9:00 a.m., New York City time, on May 19, 2005 and during the
period that commences at 5:00 p.m., New York City time, on June 22, 2005 and
ends at 9:00 a.m., New York City time, on July 7, 2005 and (B) prior to 5:00

Units by (1) depositing with the Collateral Agent the Notes then comprising such
number of Equity Security Units as is equal to such Stripped Units and (2)
instructing the Agent, in its capacity as custodian for the depositary, to
decrease the number of Stripped Units evidenced by the Global Stripped Units
Certificate(s), by a notice substantially in the form of Exhibit D hereto, and
notifying the Agent that the Holder has transferred the relevant amount of Notes
to the Collateral Agent and requesting that the Agent instruct the Collateral
Agent to release the Pledged Treasury Securities underlying

                                       28
<PAGE>

such Stripped Units (or, if the Stripped Units are held in certificated form,
transferring such Stripped Units to the Agent accompanied by a notice to the
Agent, substantially in the form of Exhibit D hereto), whereupon the Agent shall
promptly give such instruction to the Collateral Agent, substantially in the
form of Exhibit C hereto. Upon receipt of the Notes described in clause (1)
above and the instruction described in clause (2) above, in accordance with the
terms of the Pledge Agreement, the Collateral Agent will release to the Agent,
on behalf of the Holder, such Pledged Treasury Securities from the Pledge, free
and clear of the Company's security interest therein, and upon receipt thereof
the Agent shall promptly:

                  (i) decrease the number of Stripped Units evidenced by the
         Global Stripped Units Certificate(s) (or, if the Stripped Units are
         held in certificated form, cancel the related Stripped Units
         Certificates);

                  (ii) transfer the Pledged Treasury Securities to the Holder;
         and

                  (iii) increase the number of Equity Security Units evidenced
         by the Global Equity Security Units Certificate(s) (or, if the Equity
         Security Units are held in certificated form, authenticate, execute on
         behalf of such Holder and deliver an Equity Security Units Certificate
         executed by the Company in accordance with Section 3.3 evidencing the
         same number of Purchase Contracts as were evidenced by the cancelled
         Stripped Units).

         (b) Holders of Stripped Units who recreate Equity Security Units shall
be responsible for any fees or expenses payable to the Collateral Agent for its
services as Collateral Agent in respect of the substitution, and the Company
shall not be responsible for any such fees or expenses.

         (c) Holders of Stripped Units may recreate Equity Security Units only
in integral multiples of 20 Stripped Units.

         (d) In the event a Holder who recreates Equity Security Units pursuant
to this Section 3.14 fails to effect a book-entry transfer of the Stripped Units
or fails to deliver a Stripped Units Certificate to the Agent after depositing
Notes with the Collateral Agent, the Treasury Securities constituting a part of
such Stripped Units, and any distributions on such Treasury Securities shall be
held in the name of the Agent or its nominee in trust for the benefit of such
Holder, until such Stripped Units are so transferred or the Stripped Units
Certificate is so delivered, as the case may be, or, with respect to a Stripped
Units Certificate, such Holder provides evidence satisfactory to the Company and
the Agent that such Stripped Units Certificate has been destroyed, lost or
stolen, together with any indemnity that may be required by the Agent and the
Company.

         (e) Except as provided in this Section 3.14, for so long as the
Purchase Contract underlying a Stripped Unit remains in effect, the rights and
obligations of the Holder of such Stripped Unit in respect of the Treasury
Security and Purchase Contract comprising such Stripped Unit may be acquired,
and may be transferred and exchanged, only as a Stripped Unit.

         Section 3.15 Transfer of Collateral Upon Occurrence of Termination
Event.

         Upon the occurrence of a Termination Event and the transfer to the
Agent by the Collateral Agent of the Notes, the Treasury Consideration or the
Applicable Ownership Interests in the Treasury Portfolio or the Treasury
Securities, as the case may be, underlying the Equity Security

                                       29
<PAGE>

Units or the Stripped Units, as the case may be, pursuant to the terms of the
Pledge Agreement, the Agent shall request transfer instructions with respect to
such Notes, such Treasury Consideration, such Applicable Ownership Interests in
the Treasury Portfolio or such Treasury Securities, as the case may be, from
each Holder by written request mailed to such Holder at its address as it
appears in the Equity Security Units Register or the Stripped Units Register, as
the case may be. Upon book-entry transfer of the Equity Security Units or
Stripped Units or delivery of an Equity Security Units Certificate or Stripped
Units Certificate to the Agent with such transfer instructions, the Agent shall
transfer the Notes, the Treasury Consideration, the Applicable Ownership
Interests in the Treasury Portfolio or the Treasury Securities, as the case may
be, underlying such Equity Security Units or Stripped Units, as the case may be,
to such Holder by book-entry transfer, or other appropriate procedures, in
accordance with such instructions. In the event a Holder would be entitled to
receive less than $1,000 principal amount at maturity of any U.S. Treasury
security, the Agent shall dispose of such U.S. Treasury security for cash and
deliver such cash to the Holder. In the event a Holder of Equity Security Units
or Stripped Units fails to effect such transfer or delivery, the Notes, the
Treasury Consideration, the Applicable Ownership Interests in the Treasury
Portfolio or Treasury Securities, as the case may be, underlying such Equity
Security Units or Stripped Units, as the case may be, and any distributions
thereon, shall be held in the name of the Agent or its nominee in trust for the
benefit of such Holder, until:

                  (i) such Equity Security Units or Stripped Units are
         transferred or the Equity Security Units Certificate or Stripped Units
         Certificate is surrendered or such Holder provides satisfactory
         evidence that such Equity Security Units Certificate or Stripped Units
         Certificate has been destroyed, lost or stolen, together with any
         indemnity that may be required by the Agent and the Company; and

                  (ii) the expiration of the time period specified in the
         abandoned property laws of the relevant State.

         Section 3.16 No Consent to Assumption.

         Each Holder of Equity Security Units or Stripped Units, as the case may
be, by acceptance thereof, shall be deemed expressly to have withheld any
consent to the assumption under Section 365 of the Bankruptcy Code or otherwise,
of the Purchase Contract by the Company, any receiver, liquidator or person or
entity performing similar functions or its trustee in the event that the Company
becomes the debtor under the Bankruptcy Code or subject to other similar state
or federal law providing for reorganization or liquidation.

Notice.

         (a) Any payment on any Note or any distribution on the Treasury

definition of such term) in the Treasury Portfolio, as the case may be, which is
paid on any Payment Date shall, subject to receipt thereof by the Agent from

                                       30
<PAGE>

the Collateral Agent as provided by the terms of the Pledge Agreement, be paid
to the Person in whose name the Equity Security Units Certificate (or one or
more Predecessor Equity Security Units Certificates) of which such Note, such
Treasury Consideration or such Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, is a part is registered at the close of business
on the Record Date for such Payment Date.

         (b) Each Equity Security Units Certificate evidencing Notes, Treasury
Consideration or Applicable Ownership Interests in the Treasury Portfolio
delivered under this Agreement upon registration of transfer of or in exchange
for or in lieu of any other Equity Security Units Certificate shall carry the
rights to accrued and unpaid interest or distributions, or to accrue interest or
distributions, which were carried by the Notes, Treasury Consideration or
Applicable Ownership Interests in the Treasury Portfolio, as the case may be,
underlying such other Equity Security Units Certificate.

         (c) In the case of any Equity Security Units with respect to which
Early Settlement of the underlying Purchase Contract is effected on an Early
Settlement Date, Merger Early Settlement of the underlying Purchase Contract is
effected on a Merger Early Settlement Date, Cash Settlement is effected on the
eighth Business Day immediately preceding the Stock Purchase Date, or a
Collateral Substitution is effected, in each case on a date that is after any
Record Date and on or prior to the next succeeding Payment Date, payments on the
Notes, the Treasury Consideration or the Applicable Ownership Interests in the
Treasury Portfolio, as the case may be, underlying such Equity Security Units
otherwise payable on such Payment Date shall be payable on such Payment Date
notwithstanding such Early Settlement, Merger Early Settlement, Cash Settlement
or Collateral Substitution, as the case may be, and such payments shall, subject
to receipt thereof by the Agent, be payable to the Person in whose name the
Equity Security Units Certificate (or one or more Predecessor Equity Security
Units Certificates) was registered at the close of business on the Record Date.
Except as otherwise expressly provided in the immediately preceding sentence, in
the case of any Equity Security Units with respect to which Early Settlement,
Merger Early Settlement or Cash Settlement of the underlying Purchase Contract
is effected, or with respect to which a Collateral Substitution has been
effected, payments on the related Notes or payments on the Treasury
Consideration or the Applicable Ownership Interests in the Treasury Portfolio,
as the case may be, that would otherwise be payable after the applicable
Settlement Date or after such Collateral Substitution, as the case may be, shall
not be payable hereunder to the Holder of such Equity Security Units; provided,
that to the extent that such Holder continues to hold the Separate Notes that
formerly comprised a part of such Holder's Equity Security Units, such Holder
shall be entitled to receive the payments on such Separate Notes.

         Section 4.2 Notice and Voting.

         Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Pledged
Notes but only to the extent instructed by the Holders as described below. Upon
receipt of notice of any meeting at which holders of Notes are entitled to vote

the Agent shall, as soon as practicable thereafter, mail to the Holders of
Equity Security Units a notice:

                  (a) containing such information as is contained in the notice
         or solicitation,

                                       31
<PAGE>

                  (b) stating that each Holder on the record date set by the
         Agent therefor (which, to the extent possible, shall be the same date
         as the record date for determining the holders of Notes entitled to
         vote) shall be entitled to instruct the Agent as to the exercise of the
         voting rights pertaining to the Pledged Notes underlying their Equity
         Security Units; and

                  (c) stating the manner in which such instructions may be
         given.

         Upon the written request of the Holders of Equity Security Units on
such record date, the Agent shall endeavor insofar as practicable to vote or
cause to be voted, in accordance with the instructions set forth in such
requests, the maximum number of Pledged Notes as to which any particular voting
instructions are received. In the absence of specific instructions from the
Holder of an Equity Security Unit, the Agent shall abstain from voting the
Pledged Note underlying such Equity Security Units. The Company hereby agrees,
if applicable, to solicit Holders of Equity Security Units to timely instruct
the Agent in order to enable the Agent to vote such Pledged Notes.

         Section 4.3 Tax Event Redemption.

         Upon the occurrence of a Tax Event Redemption prior to the earlier of a
successful remarketing of the Notes and the Stock Purchase Date, the Collateral
Agent shall apply, out of the aggregate Redemption Price for the Pledged Notes,
an amount equal to the aggregate Redemption Amount for the Pledged Notes to
purchase on behalf of the Holders of Equity Security Units the Treasury
Portfolio and promptly remit the remaining portion, if any, of such aggregate
Redemption Price to the Agent for payment to the Holders of such Equity Security
Units. The Treasury Portfolio will be substituted for the Pledged Notes, and
will be pledged to the Collateral Agent in accordance with the terms of the
Pledge Agreement to secure the obligation of each Holder of an Equity Security
Units to purchase the Common Stock under the Purchase Contract constituting a
part of such Equity Security Unit.

         Following the occurrence of a Tax Event Redemption prior to the earlier
of a successful remarketing of the Notes and the Stock Purchase Date, the
Holders of Equity Security Units and the Collateral Agent shall have such
security interests, rights and obligations with respect to the Treasury
Portfolio as the Holder of Equity Security Units and the Collateral Agent had in
respect of the Notes, as the case may be, subject to the Pledge thereof as
provided in Articles II, III, IV, V and VI of the Pledge Agreement, and any
reference herein or in the Certificates to the Note shall be deemed to be a
reference to such Treasury Portfolio and any reference herein or in the
Certificates to interest on the Notes shall be deemed to be a reference to
corresponding distributions on the Treasury Portfolio. The Company may cause to
be made in any Equity Security Units Certificates thereafter to be issued such
change in phraseology and form (but not in substance) as may be appropriate to
reflect the substitution of the Treasury Portfolio for Notes as collateral.

         The Company shall cause notice of any Tax Event Redemption to be
mailed, at least 30 calendar days but not more than 60 calendar days before such
Tax Event Redemption Date, to each Holder of Equity Security Units including
Notes to be redeemed at its registered address.

         Upon the occurrence of a Tax Event Redemption after the earlier of a
successful remarketing of the Notes or the Stock Purchase Date, the Redemption
Price will be payable in cash to the holders of the Notes.

                                   ARTICLE V.
                     THE PURCHASE CONTRACTS; THE REMARKETING

         Section 5.1 Purchase of Shares of Common Stock.

         (a) Each Purchase Contract shall, unless (x) an Early Settlement has
occurred in accordance with Section 5.9, (y) a Merger Early Settlement has
occurred in accordance with Section 5.10 or (z) a Termination Event has occurred
in accordance with Section 5.8, obligate the Holder of the related Equity
Security Unit or Stripped Unit, as the case may be, to purchase, and the Company
to sell, on the Stock Purchase Date at a price equal to $50 (the "Purchase
Price"), a number of newly issued shares of Common Stock equal to the Settlement
Rate. The "Settlement Rate" is equal to:

                  (i) if the Applicable Market Value is greater than or equal to
         $23.94 (the "Threshold Appreciation Price"), 2.0886 shares of Common
         Stock per Purchase Contract;

                  (ii) if the Applicable Market Value is less than the Threshold
         Appreciation Price but is greater than $19.95 (the "Reference Price"),
         the number of shares of Common Stock per Purchase Contract equal to the
         Stated Amount divided by the Applicable Market Value; and

                  (iii) if the Applicable Market Value is equal to or less than
         the Reference Price, 2.5063 shares of Common Stock per Purchase
         Contract,

in each case subject to adjustment as provided in Section 5.6 and in each case
rounded upward or downward to the nearest 1/10,000th of a share.

         As provided in Section 5.12, no fractional shares of Common Stock will
be issued upon settlement of Purchase Contracts.

         Promptly after the calculation of the Settlement Rate and the
Applicable Market Value, the Company shall give the Agent notice thereof. All
calculations and determinations of the Settlement Rate and the Applicable Market
Value shall be made by the Company or its agents based on their good faith
calculations, and the Agent shall have no responsibility with respect thereto.

         (b) The "Applicable Market Value" means the average of the Closing
Price per share of Common Stock on each of the 20 consecutive Trading Days
ending on the third Trading Day immediately preceding the Stock Purchase Date;
provided, that, in the case of a Merger Early Settlement, the 20 consecutive
Trading Days shall end on the date of completion of the Cash Merger.

         The "Closing Price" of the Common Stock on any date of determination
means:

                  (i) the closing sale price (or, if no closing price is
         reported, the last reported sale price) of the Common Stock on the NYSE
         on such date;

                                       33
<PAGE>

                  (ii) if the Common Stock is not listed for trading on the NYSE
         on any such date, as reported in the composite transactions for the
         principal United States securities exchange on which the Common Stock
         is so listed;

                  (iii) if the Common Stock is not so listed on a United States
         national or regional securities exchange, as reported by the Nasdaq
         Stock Market;

                  (iv) if the Common Stock is not so reported, the last quoted
         bid price for the Common Stock in the over-the-counter market as
         reported by the National Quotation Bureau or similar organization; or

                  (v) if such bid price is not available, the market value of
         the Common Stock on such date as determined by a nationally recognized
         independent investment banking firm retained for this purpose by the
         Company.

         A "Trading Day" means a day on which the Common Stock:

                  (i) is not suspended from trading on any national or regional
         securities exchange or association or over-the-counter market at the
         close of business; and

                  (ii) has traded at least once on the national or regional
         securities exchange or association or over-the-counter market that is
         the primary market for the trading of the Common Stock.

         (c) Each Holder of Equity Security Units or Stripped Units, as the case
may be, by its acceptance thereof, irrevocably authorizes the Agent to enter
into and perform the related Purchase Contract on its behalf as its
attorney-in-fact (including the execution of Certificates on behalf of such
Holder), agrees to be bound by the terms and provisions thereof, covenants and
agrees to perform its obligations under such Purchase Contracts, and consents to
the provisions hereof, irrevocably authorizes the Agent as its attorney-in-fact
to enter into and perform the Pledge Agreement on its behalf as its
attorney-in-fact, and consents to and agrees to be bound by the Pledge of the
Notes, the Treasury Consideration, the Applicable Ownership Interests in the
Treasury Portfolio or the Treasury Securities pursuant to the Pledge Agreement.
Each Holder of Equity Security Units or Stripped Units, as the case may be, by
its acceptance thereof, further covenants and agrees that, to the extent and in
the manner provided in Section 5.4 and the Pledge Agreement, but subject to the
terms thereof, payments in respect of the Notes, the Treasury Consideration, the
Applicable Ownership Interests in the Treasury Portfolio or the Treasury
Securities, to be paid upon settlement of such Holder's obligations to purchase
Common Stock under the Purchase Contract, shall be paid on the Stock Purchase
Date by the Collateral Agent to the Company in satisfaction of such Holder's
obligations under such Purchase Contract and such Holder shall acquire no right,
title or interest in such payment.

         (d) Upon registration of transfer of a Certificate, the transferee
shall be bound (without the necessity of any other action on the part of such
transferee) under the terms of this Agreement, the Purchase Contracts underlying
such Certificate and the Pledge Agreement, and the transferor shall be released
from the obligations under this Agreement, the Purchase Contracts underlying the
Certificates so transferred and the Pledge Agreement. The Company covenants and
agrees, and

                                       34
<PAGE>

each Holder of a Certificate, by its acceptance thereof, likewise covenants and
agrees, to be bound by the provisions of this paragraph.

         Section 5.2 Contract Adjustment Payments.

         (a) Contract Adjustment Payments shall accumulate on each Purchase
Contract constituting a part of an Equity Security Unit or Stripped Unit at
2.86% per year of the Stated Amount of such Equity Security Unit or Stripped
Unit, from June 26, 2002 through and including the Stock Purchase Date. Subject
to Section 5.3 herein, the Company shall pay, on each Payment Date, the Contract
Adjustment Payments, if any, payable in respect of each Purchase Contract to the
Person in whose name a Certificate (or one or more Predecessor Certificates) is
registered at the close of business on the Record Date immediately preceding
such Payment Date in such coin or currency of the United States as at the time
of payment shall be legal tender for payments. The Contract Adjustment Payments,
if any, will be payable at the Office of the Agent in The City of New York or,
at the option of the Company, by check mailed to the address of the Person
entitled thereto at such Person's address as it appears on the Register or by
wire transfer to the account designated to the Agent by a prior written notice
by such Person delivered at least five Business Days prior to the applicable
Payment Date.

         (b) Each Certificate delivered under this Agreement upon registration
of transfer of or in exchange for or in lieu of (including as a result of a
Collateral Substitution or the recreation of an Equity Security Unit) any other
Certificate shall carry the rights to Contract Adjustment Payments, if any,
accumulated and unpaid, and to accumulate Contract Adjustment Payments, if any,
which were carried by the Purchase Contracts underlying such other Certificates.

         (c) Upon the occurrence of a Termination Event, the Company's
obligation to pay Contract Adjustment Payments (including any accumulated
Deferred Contract Adjustment Payments), if any, shall cease.

         (d) Subject to Sections 5.9 and 5.10, in the case of any Equity
Security Units or Stripped Units, as the case may be, with respect to which
Early Settlement or Merger Early Settlement of the underlying Purchase Contract
is effected on an Early Settlement Date or a Merger Early Settlement Date,
respectively, that is after any Record Date and on or prior to the next
succeeding Payment Date, Contract Adjustment Payments on the Purchase Contract
underlying such Equity Security Units or Stripped Units, as the case may be,
otherwise payable on such Payment Date shall be payable on such Payment Date
notwithstanding such Early Settlement or Merger Early Settlement, and such
Contract Adjustment Payments shall be paid to the Person in whose name the
Certificate evidencing such Equity Security Units or Stripped Units (or one or
more Predecessor Certificates) is registered at the close of business on such
Record Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Equity Security Units or Stripped Units with
respect to which Early Settlement or Merger Early Settlement of the underlying
Purchase Contracts is effected on an Early Settlement Date or Merger Early
Settlement Date, respectively, Contract Adjustment Payments that would otherwise
be payable after the Early Settlement Date, or Merger Early Settlement Date, as
the case may be, with respect to such Purchase Contracts shall not be payable.

                                       35
<PAGE>

         (e) The Company's obligations with respect to the Contract Adjustment
Payments will rank equally with all of the Company's existing and future
unsecured and unsubordinated indebtedness.

         Section 5.3 Deferral of Contract Adjustment Payments.

         (a) The Company shall have the right, at any time prior to the Stock
Purchase Date, to defer the payment of any or all of the Contract Adjustment
Payments otherwise payable on any Payment Date, but only if the Company shall
give the Holders and the Agent written notice of its election to defer each such
deferred Contract Adjustment Payment (specifying the amount to be deferred) at
least ten Business Days prior to the earlier of (i) the next succeeding Payment
Date and (ii) the date the Company is required to give notice of the Record Date
or Payment Date with respect to payment of such Contract Adjustment Payments to
the NYSE or other applicable self-regulatory organization or to Holders of the
Equity Security Units and Stripped Units, but in any event not less than one
Business Day prior to such Record Date. Any Contract Adjustment Payments so
deferred shall, to the extent permitted by law, bear additional Contract
Adjustment Payments thereon at the rate of 6.14% per year (computed on the basis
of a 360-day year of twelve 30-day months), compounding on each succeeding
Payment Date, until paid in full (such deferred installments of Contract
Adjustment Payments, if any, together with the additional Contract Adjustment
Payments accrued thereon, being referred to herein as the "Deferred Contract
Adjustment Payments"). Deferred Contract Adjustment Payments, if any, shall be
due on the next succeeding Payment Date except to the extent that payment is
deferred pursuant to this Section 5.3. No Contract Adjustment Payments may be
deferred to a date that is after the Stock Purchase Date and no such deferral
period may end other than on a Payment Date. If the Purchase Contracts are
terminated upon the occurrence of a Termination Event, the Holder's right to
receive Contract Adjustment Payments, if any, and Deferred Contract Adjustment
Payments, if any, will terminate.

         (b) In the event that the Company elects to defer the payment of
Contract Adjustment Payments on the Purchase Contracts until a Payment Date
prior to the Stock Purchase Date, then all Deferred Contract Adjustment
Payments, if any, shall be payable to the registered Holders as of the close of
business on the Record Date immediately preceding such Payment Date.

         (c) In the event that the Company elects to defer the payment of
Contract Adjustment Payments on the Purchase Contracts until the Stock Purchase
Date, the Company may elect to pay each Holder on the Stock Purchase Date in
respect of the Deferred Contract Adjustment Payments, in lieu of a cash payment,
a number of shares of Common Stock (in addition to the number of shares of
Common Stock equal to the Settlement Rate) equal to (A) the aggregate amount of
Deferred Contract Adjustment Payments payable to such Holder (net of any
required tax withholding on such Deferred Contract Adjustment Payments, which
shall be remitted to the appropriate taxing jurisdiction) divided by (B) the
Applicable Market Value.

         (d) No fractional shares will be issued by the Company with respect to
the payment of Deferred Contract Adjustment Payments on the Stock Purchase Date.
In lieu of fractional shares otherwise issuable with respect to such payment of
Deferred Contract Adjustment Payments, the Holder will be entitled to receive an
amount in cash as provided in Section 5.12.

                                       36
<PAGE>
         (e) In the event the Company exercises its option to defer the payment
of Contract Adjustment Payments then, until the Deferred Contract Adjustment
Payments have been paid, the Company shall not declare or pay dividends on, make
distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of the Company's Common Stock other
than:

                  (i) purchases, redemptions or acquisitions of shares of Common
         Stock in connection with any employment contract, benefit plan or other
         similar arrangement with or for the benefit of employees, officers or
         directors or a stock purchase or dividend reinvestment plan, or the
         satisfaction by the Company of its obligations pursuant to any contract
         or security outstanding on the date the Company exercises its right to
         defer the Contract Adjustment Payments;

                  (ii) as a result of a reclassification of the Company's
         Capital Stock or the exchange or conversion of one class or series of
         the Company's Capital Stock for another class or series of the
         Company's Capital Stock;

                  (iii) the purchase of fractional interests of the Common Stock
         pursuant to the conversion or exchange provisions of such Common Stock
         or the security being converted or exchanged;

                  (iv) dividends or distributions in any series of the Company's
         Common Stock (or rights to acquire Common Stock) or repurchases,
         acquisitions or redemptions of Common Stock in connection with the
         issuance or exchange of the Common Stock (or securities convertible
         into or exchangeable for shares of the Company's Common Stock); or

                  (v) redemptions, exchanges or repurchases of any rights
         outstanding under a shareholder rights plan or the declaration or
         payment thereunder of a dividend or distribution of or with respect to
         rights in the future.

         Section 5.4 Payment of Purchase Price; Remarketing.

         (a) (i) Unless a Tax Event Redemption, successful remarketing or
Termination Event has occurred or a Merger Early Settlement or Early Settlement
has been effected, each Holder of an Equity Security Unit may pay in cash ("Cash
Settlement") the Purchase Price for the shares of Common Stock to be purchased
pursuant to a Purchase Contract if such Holder notifies the Agent by use of a
notice in substantially the form of Exhibit E hereto of its intention to make a
Cash Settlement. Such notice shall be made not earlier than 9:00 a.m., New York
City time, on the tenth Business Day immediately preceding the Stock Purchase
Date and not later than 5:00 p.m., New York City time, on the ninth Business Day
immediately preceding the Stock Purchase Date. The Agent shall promptly notify
the Collateral Agent of the receipt of such a notice from a Holder intending to
make a Cash Settlement.

             (ii) A Holder of an Equity Security Unit who has so notified the
Agent of its intention to make a Cash Settlement by use of a notice in
substantially the form of Exhibit E hereto is required to pay the Purchase Price
to the Collateral Agent not later than 11:00 a.m., New York City time, on the
eighth Business Day immediately preceding the Stock Purchase Date in lawful

                                       37
<PAGE>

money of the United States by certified or cashiers' check or wire transfer, in
each case in immediately available funds and payable to or upon the order of the
Company. The Collateral Agent shall promptly notify the Remarketing Agent of the
amount of cash received pursuant to this Section 5.4(a)(ii), which will
consequently reduce the aggregate number of Pledged Notes to be remarketed that
the Collateral Agent had previously notified the Remarketing Agent of pursuant
to Section 5.4(b). Any cash received by the Collateral Agent will be paid to the
Company on the Stock Purchase Date in settlement of the Purchase Contract in
accordance with the terms of this Agreement and the Pledge Agreement.

             (iii) If a Holder of an Equity Security Unit notifies the Agent as
provided in this Section 5.4(a)(i) of its intention to pay the Purchase Price in
cash, but fails to make such payment as required by Section 5.4(a)(ii), the
Holder shall be deemed to have consented to the disposition of the Pledged Notes
pursuant to the remarketing as described in Section 5.4(b).

         (b) The Company has engaged the Remarketing Agent to sell the Notes of
(A) Holders of Equity Security Units and (B) holders of Separate Notes that have
elected to participate in the remarketing pursuant to the procedures set forth
in Section 2.06 of the Supplemental Indenture and Section 4.5(d) of the Pledge
Agreement. On the seventh Business Day prior to the Initial Remarketing Date or
the first day of any subsequent Remarketing Period, as applicable, the Company
shall give holders of Separate Notes notice of the upcoming remarketing in a
daily newspaper in the English language of general circulation in The City of
New York, which is expected to be The Wall Street Journal. In addition, the
Company will request not later than seven nor more than 15 calendar days prior
to the Initial Remarketing Date or the first day of any subsequent Remarketing
Period, as applicable, that the Depositary notify, directly or indirectly, each
Beneficial Owner or Clearing Agency Participant holding an Equity Security Unit
or Stripped Units and each Beneficial Owner of a Separate Note of the upcoming
remarketing and of the procedures that must be followed in connection with the
upcoming remarketing, as applicable. At any time after the Payment Date
immediately preceding the last Payment Date before the Stock Purchase Date and
prior to 11:00 a.m., New York City time, on the fourth Business Day immediately
preceding the Initial Remarketing Date or the first day of any subsequent
Remarketing Period, as applicable, holders of Separate Notes may elect to have
their Separate Notes remarketed by Transferring such Separate Notes and
delivering a notice of such election, substantially in the form of Exhibit C to
the Pledge Agreement, to the Custodial Agent. Pursuant to the terms of the
Pledge Agreement, the Custodial Agent will hold such Separate Notes in an
account separate from the Collateral Account. A holder of Separate Notes
electing to have its Separate Notes remarketed will also have the right to
withdraw such election by written notice to the Custodial Agent, substantially
in the form of Exhibit D to the Pledge Agreement, prior to 11:00 a.m., New York
City time, on the fourth Business Day immediately preceding the Initial
Remarketing Date or the first day of any subsequent Remarketing Period, as
applicable, upon which notice the Custodial Agent will return such Separate
Notes to such holder. On the third Business Day immediately preceding the
Initial Remarketing Date or the first day of any subsequent Remarketing Period,
as applicable, not later than 10:00 a.m., New York City time, pursuant to the
terms of the Pledge Agreement, the Custodial Agent will notify the Remarketing
Agent of the aggregate number of Separate Notes to be remarketed. On the third
Business Day immediately preceding the Initial Remarketing Date or the first day
of any subsequent Remarketing Period, as applicable, not later than 10:00 a.m.,
New York City time, pursuant to the terms of the Pledge Agreement, the
Collateral Agent will notify the Remarketing Agent of the

                                       38
<PAGE>

aggregate number of Pledged Notes to be remarketed. On the third Business Day
immediately preceding the Initial Remarketing Date or the first day of any
subsequent Remarketing Period, as applicable, the Collateral Agent and the
Custodial Agent, pursuant to the terms of the Pledge Agreement, will deliver to
the Remarketing Agent for remarketing all Notes to be remarketed.

         (c) Upon receipt of such notice from the Collateral Agent and the
Custodial Agent and such Notes from the Collateral Agent and the Custodial
Agent, the Remarketing Agent will, on the Initial Remarketing Date, use its
commercially reasonable best efforts to (i) establish the Reset Rate (as defined
in clause (i) of the definition of such term) and (ii) sell the Notes
participating in such remarketing on such date at a price equal to
approximately, but not less than, 100.5% of the Remarketing Value.

         (d) If, despite using its commercially reasonable best efforts, the
Remarketing Agent cannot, on the Initial Remarketing Date, establish the Reset
Rate (as defined in clause (i) of the definition of such term) and remarket the
Notes participating in the remarketing at a price equal to approximately, but
not less than, 100.5% of the Remarketing Value, the Remarketing Agent will again
attempt to establish the Reset Rate (as defined in clause (i) of the definition
of such term) and remarket the Notes participating in such remarketing at a
price equal to approximately, but not less than, 100.5% of the Remarketing Value
on each of the two next succeeding Business Days. If the Remarketing Agent
cannot remarket the Notes participating in the remarketing at a price equal to
approximately, but not less than, 100.5% of the Remarketing Value on either of
those days, it will attempt to establish the Reset Rate (as defined in clause
(i) of the definition of such term) and remarket the Notes participating in the
remarketing at a price equal to approximately, but not less than, 100.5% of the
Remarketing Value on each of the three Business Days immediately preceding July
1, 2005. If the Remarketing Agent cannot establish the Reset Rate (as defined in
clause (i) of the definition of such term) and remarket the Notes participating
in the remarketing at a price equal to approximately, but not less than, 100.5%
of the Remarketing Value either on the Initial Remarketing Date or any of the
two Business Days next succeeding the Initial Remarketing Date or on any of the
three Business Days immediately preceding July 1, 2005, the remarketing in each
such remarketing period will be deemed to have failed (each, a "Failed
Remarketing"). If there have been two Failed Remarketings, the Remarketing Agent
will further attempt to establish the Reset Rate (as defined in clause (i) of
the definition of such term) and remarket the Notes participating in the
remarketing at a price equal to approximately, but not less than, 100.5% of the
Remarketing Value on each of the seventh, sixth and fifth Business Days
immediately preceding the Stock Purchase Date. If, despite using its
commercially reasonable best efforts, the Remarketing Agent fails to remarket
the Notes participating in the remarketing at a price equal to approximately,
but not less than, 100.5% of the Remarketing Value by 4:00 p.m., New York City
time, on the fifth Business Day immediately preceding the Stock Purchase Date,
the "Last Failed Remarketing" will be deemed to have occurred.

         (e) Upon the occurrence of a successful remarketing, the Remarketing
Agent shall, by approximately 4:30 p.m., New York City time, on the date of the
successful remarketing, advise, by telephone (promptly confirmed in writing) the
Company, the Agent, the Collateral Agent, the Custodial Agent, the Securities
Intermediary, the Depositary and the Trustee of the Reset Rate determined in the
remarketing in accordance with clause (i) of the definition of Reset Rate, and
shall use the proceeds from the successful remarketing attributable to the
Pledged Notes to purchase the appropriate U.S. Treasury securities (the
"Treasury Consideration") with the CUSIP

                                       39
<PAGE>

numbers, if any, selected by the Remarketing Agent, described in clauses (1) and
(2) of the definition of Remarketing Value. On the date of settlement of the
successful remarketing, which shall be the third Business Day following the
Initial Remarketing Date or any Subsequent Remarketing Date, as the case may be,
the Remarketing Agent shall deliver such Treasury Consideration to the Agent,
which shall thereupon deliver such Treasury Consideration to the Collateral
Agent. Upon receipt of such Treasury Consideration from the Agent, the
Collateral Agent, for the benefit of the Company, will thereupon apply such
Treasury Consideration, in accordance with the Pledge Agreement, to secure such
Equity Security Units Holders' obligations under the Purchase Contracts and to
fund the quarterly payment due to Equity Security Units Holders on the Stock
Purchase Date in an amount equal to the quarterly interest payment on the Notes,
calculated at the initial annual interest rate. On the third Business Day
following such Initial Remarketing Date or Subsequent Remarketing Date, as the
case may be, the Remarketing Agent also shall:

                  (i) deduct and retain for itself as a remarketing fee an
         amount not exceeding 25 basis points (0.25%) of the total proceeds from
         the remarketing (the "Remarketing Fee");

                  (ii) remit the remaining portion of the proceeds from the
         successful remarketing attributable to the Separate Notes to the
         Custodial Agent for payment to the holders of Separate Notes that were
         remarketed; and

                  (iii) remit the remaining portion, if any, of the proceeds to
         the Agent for payment to the Holders of the Equity Security Units.

Holders whose Notes are so remarketed will not otherwise be responsible for the
payment of any Remarketing Fee in connection therewith.

         (f) Upon the occurrence of a Failed Remarketing, the Remarketing Agent
shall notify by telephone the Company, the Agent, the Collateral Agent, the
Custodial Agent and the Trustee that a Failed Remarketing has occurred,
whereupon the Company shall notify the Depositary, by telephone, that a Failed
Remarketing has occurred. The Company also shall cause a notice of the Failed
Remarketing to be published not later than the fourth Business Day following the
last day of such Remarketing Period by means of Bloomberg and Reuters newswires
and a daily newspaper in the English language of general circulation in The City
of New York, which is expected to be The Wall Street Journal. The Remarketing
Agent also shall, within three Business Days following the last day of such
Remarketing Period, return the Pledged Notes that were to be remarketed to the
Collateral Agent and the Separate Notes that were to be remarketed to the
Custodial Agent for redelivery to such holders of such Separate Notes.

         (g) Upon the occurrence of the Last Failed Remarketing, the Remarketing
Agent shall notify by telephone the Company, the Agent, the Collateral Agent,
the Custodial Agent and the Trustee that the Last Failed Remarketing has
occurred, whereupon the Company shall notify the Depositary that the Last Failed
Remarketing has occurred. The Company also shall cause a notice of the Last
Failed Remarketing to be published not later than the fourth Business Day
following the fifth Business Day immediately preceding the Stock Purchase Date
by means of Bloomberg and Reuters newswires and a daily newspaper in the English
language of general circulation in the City of New York, which is expected to be
The Wall Street Journal. The Remarketing Agent also

                                       40

shall, within three Business Days following the fifth Business Day immediately
preceding the Stock Purchase Date, return the Pledged Notes to the Collateral
Agent and the Separate Notes that were to be remarketed to the Custodial Agent
for redelivery to such holders of such Separate Notes. The Collateral Agent, for
the benefit of the Company, may exercise its rights as a secured party with
respect to the Pledged Notes, including those actions specified in Section
5.4(h) below, and the Holders of Equity Security Units, by their acceptance of
the Equity Security Units shall be deemed to have agreed to such exercise by the
Collateral Agent in such case; provided, that if upon the Last Failed
Remarketing, the Collateral Agent delivers any Notes to the Company in full
satisfaction of the Holder's obligation under the related Purchase Contracts,
any accrued and unpaid interest on such Notes will become payable by the Company
to the Agent for payment to the Holder of the Equity Security Units to which
such Notes relate. Such payment will be made by the Company not later than 11:00
a.m., New York City time, on the Stock Purchase Date in lawful money of the
United States by certified or cashier's check or wire transfer in immediately
available funds payable to or upon the order of the Agent.

         (h) Upon the occurrence of the Last Failed Remarketing, pursuant to the
written direction of the Company, the Collateral Agent, for the benefit of the
Company, reserves all of its rights as a secured party with respect thereto and,
subject to applicable law and Section 5.4(k) below, will sell or deliver the
Pledged Notes in accordance with the Company's written direction to satisfy in
full, from any such sale or delivery, such Holders' obligations under the
related Purchase Contracts to pay the Purchase Price for the Common Stock and
the Holders of the Equity Security Units, by their acceptance of the Equity
Security Units shall be deemed to have agreed to such action by the Collateral
Agent.

         (i) Upon the maturity of the Pledged Treasury Consideration (as defined
in clause (2) of the definition of Remarketing Value) or Pledged Applicable
Ownership Interests (as defined in clause (A) of the definition of Applicable
Ownership Interest) in the Treasury Portfolio, as the case may be, underlying
the Equity Security Units, and the Pledged Treasury Securities underlying the
Stripped Units on the Stock Purchase Date, the Collateral Agent shall remit to
the Company an amount equal to the aggregate Purchase Price applicable to such
Equity Security Units and Stripped Units, as payment for the Common Stock
issuable upon settlement thereof without receiving any instructions from the
Holders of such Equity Security Units and Stripped Units. In the event the
payments in respect of the Pledged Treasury Consideration or Pledged Applicable
Ownership Interest in the Treasury Portfolio underlying an Equity Security Unit
or Pledged Treasury Securities underlying Stripped Units are in excess of the
Purchase Price under the Purchase Contract(s) being settled thereby, the
Collateral Agent will distribute such excess to the Agent for the benefit of the
Holders of such Equity Security Units or Stripped Units when received.

         (j) Any distribution to Holders of excess funds and interest described
in Section 5.4(e), (g) and (i) above shall be payable at the Office of the Agent
in The City of New York maintained for that purpose or, at the option of the
Holder or the holder of Separate Notes, as applicable, by check mailed to the
address of the Person entitled thereto at such address as it appears on the
relevant Register or by wire transfer to an account specified by the Holder or
the holder of Separate Notes, as applicable.

                                       41
<PAGE>

         (k) The obligations of each Holder to pay the Purchase Price are
non-recourse obligations and except to the extent paid by Cash Settlement, Early
Settlement or Merger Early Settlement, are payable solely out of the proceeds of
any Collateral pledged to secure the obligations of the Holder, and in no event
will any Holder be liable for any deficiency between such proceeds and the
Purchase Price.

         (l) Notwithstanding anything to the contrary contained herein, the
Company shall not be obligated to issue any Common Stock in respect of a
Purchase Contract or deliver any certificates therefor to the Holder of the
related Equity Security Units or Stripped Units, as the case may be, unless the
Company shall have received payment in full for the shares of Common Stock to be
purchased thereunder by such Holder in the manner herein set forth, which
payment, in the case of Equity Security Units upon the occurrence of the Last
Failed Remarketing, shall occur by the resale or retention and cancellation of
such Pledged Notes.

         Section 5.5 Issuance of Shares of Common Stock.

         Unless a Termination Event shall have occurred on or prior to the Stock
Purchase Date or Early Settlement or Merger Early Settlement shall have been
effected with respect to all of the outstanding Equity Security Units and
Stripped Units, on the Stock Purchase Date, upon its receipt of payment for the
shares of Common Stock purchased by the Holders pursuant to the provisions of
this Article and subject to Section 5.4, including payment in the case of Equity
Security Units upon the occurrence of the Last Failed Remarketing by the resale
or retention and cancellation of such Pledged Notes, the Company shall issue and
deposit with the Agent, for the benefit of the Holders of the Outstanding Units,
one or more certificates or book-entry interests representing the newly issued
shares of Common Stock registered in the name of the Agent (or its nominee) as
custodian for the Holders (such certificates or book-entry interests for shares
of Common Stock, together with any dividends or distributions for which a record
date and payment date for such dividend or distribution has occurred after the
Stock Purchase Date, being hereinafter referred to as the "Purchase Contract
Settlement Fund") to which the Holders are entitled hereunder. Subject to the
foregoing, upon surrender of a Certificate to the Agent on or after the Stock
Purchase Date, together with settlement instructions thereon duly completed and
executed, the Holder of such Certificate shall be entitled to receive in
exchange therefor a certificate or book-entry interest representing that number
of whole shares of Common Stock which such Holder is entitled to receive
pursuant to the provisions of this Article V (after taking into account all
Equity Security Units and Stripped Units then held by such Holder) together with
cash in lieu of fractional shares as provided in Section 5.12 and any dividends
or distributions with respect to such shares constituting part of the Purchase
Contract Settlement Fund, but without any interest thereon, and the Certificate
so surrendered shall forthwith be cancelled. Such shares shall be registered in
the name of the Holder or the Holder's designee as specified in the settlement
instructions provided by the Holder to the Agent. If any shares of Common Stock
issued in respect of a Purchase Contract are to be registered to a Person other
than the Person in whose name the Certificate evidencing such Purchase Contract
is registered, no such registration shall be made unless the Person requesting
such registration has paid any transfer and other taxes required by reason of
such registration in a name other than that of the registered Holder of such
Certificate or has established to the satisfaction of the Company that such tax
either has been paid or is not payable.

         Section 5.6 Adjustment of Settlement Rate.

         (a) Adjustments for Dividends, Distributions, Stock Splits, Etc.

         (1) Stock Dividends. In case the Company shall pay or make a dividend
or other distribution on the Common Stock in Common Stock, the Settlement Rate
and Early Settlement Rate in effect at the opening of business on the day
following the date fixed for the determination of stockholders entitled to
receive such dividend or other distribution shall be increased by dividing such
Settlement Rate or Early Settlement Rate, as applicable, by a fraction, of which
the numerator shall be the number of shares of Common Stock outstanding at the
close of business on the date fixed for such determination and the denominator
shall be the sum of such number of shares and the total number of shares
constituting such dividend or other distribution, such increases to become
effective immediately after the opening of business on the day following the
date fixed for such determination. If any dividend or distribution of the type
described in this Section 5.6(a)(1) is declared but not so paid or made, the
Settlement Rate and Early Settlement Rate shall be readjusted to the Settlement
Rate and Early Settlement Rate which would then be in effect if such dividend or
distribution had not been declared. For the purposes of this Section 5.6(a)(1),
the number of shares of Common Stock at the time outstanding shall not include
shares held in the treasury of the Company but shall include any shares issuable
in respect of any scrip certificates issued in lieu of fractions of shares of
Common Stock. The Company will not pay any dividend or make any distribution on
shares of Common Stock held in the treasury of the Company.

         (2) Stock Purchase Rights. In case the Company shall issue rights,
options or warrants to all holders of its Common Stock (not being available on
an equivalent basis to Holders of the Equity Security Units and Stripped Units
upon settlement of the Purchase Contracts underlying such Equity Security Units
and Stripped Units) entitling them to subscribe for or purchase shares of Common
Stock at a price per share less than the Current Market Price per share of the
Common Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than pursuant to a dividend
reinvestment, share purchase or similar plan), the Settlement Rate and Early
Settlement Rate in effect at the opening of business on the day following the
date fixed for the determination of stockholders entitled to receive such
rights, options or warrants shall be increased by dividing such Settlement Rate
or Early Settlement Rate, as applicable, by a fraction, of which the numerator
shall be the number of shares of Common Stock outstanding at the close of
business on the date fixed for such determination plus the number of shares of
Common Stock which the aggregate of the offering price of the total number of
shares of Common Stock so offered for subscription or purchase would purchase at
such Current Market Price and the denominator shall be the number of shares of
Common Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so offered for
subscription or purchase, such increases to become effective immediately after
the opening of business on the day following the date fixed for such
determination. To the extent that shares of Common Stock are not delivered
pursuant to such rights, options or warrants, upon the expiration or termination
of such rights, options or warrants, the Settlement Rate and Early Settlement
Rate shall be readjusted to be the Settlement Rate and Early Settlement Rate
which would then be in effect had the adjustments made upon the issuance of such
rights, options and warrants been made on the basis of delivery of only the
number of shares of Common Stock actually delivered. For the purposes of this
Section 5.6(a)(2), the number of shares of Common

                                       43
<PAGE>

Stock at any time outstanding shall not include shares held in the treasury of
the Company but shall include any shares issuable in respect of any scrip
certificates issued in lieu of fractions of shares of Common Stock. The Company
shall not issue any such rights, options or warrants in respect of shares of
Common Stock held in the treasury of the Company.

         (3) Stock Splits; Reverse Splits. In case outstanding shares of Common
Stock shall be subdivided or split into a greater number of shares of Common
Stock, the Settlement Rate and Early Settlement Rate in effect at the opening of
business on the day following the day upon which such subdivision or split
becomes effective shall be proportionately increased, and, conversely, in case
outstanding shares of Common Stock shall be combined into a smaller number of
shares of Common Stock, the Settlement Rate or Early Settlement Rate, as
applicable, in effect at the opening of business on the day following the day
upon which such combination becomes effective shall be proportionately reduced,
such increases or reductions, as the case may be, to become effective
immediately after the opening of business on the day following the day upon
which such subdivision, split or combination becomes effective.

         (4) Debt or Asset Distributions. (i) In case the Company shall, by
dividend or otherwise, distribute to all holders of its Common Stock evidences
of its indebtedness or assets (including securities, but excluding any rights or
warrants referred to in Section 5.6(a)(2), any dividend or distribution paid
exclusively in cash and any dividend, shares of capital stock of any class or
series, or similar equity interests, of or relating to a subsidiary or other
business unit in the case of a Spin-Off referred to in the next paragraph, or
distribution referred to in Section 5.6(a)(1), the Settlement Rate and Early
Settlement Rate in effect at the opening of business on the day following the
date fixed for the determination of stockholders entitled to receive such
distribution shall be adjusted by dividing such Settlement Rate or Early
Settlement Rate, as applicable, by a fraction, of which the numerator shall be
the Current Market Price per share of the Common Stock on the day following the
date fixed for such determination less the then fair market value (as determined
by the Board of Directors, whose determination shall be conclusive and described
in a Board Resolution) of the portion of the assets or evidences of indebtedness
so distributed applicable to one share of Common Stock and the denominator shall
be such Current Market Price per share of the Common Stock, such adjustments to
become effective immediately after the opening of business on the day following
the date fixed for such determination of stockholders entitled to receive such
distribution. In any case in which this Section 5.6(a)(4) is applicable, Section
5.6(a)(2) of this Section shall not be applicable.

         (ii) In the case of a Spin-Off, the Settlement Rate and Early
Settlement Rate in effect immediately before the close of business on the record
date fixed for determination of stockholders entitled to receive that
distribution will be increased by multiplying the Settlement Rate or Early
Settlement Rate, as applicable, by a fraction, of which the numerator is the
Current Market Price per share of the Common Stock plus the Fair Market Value of
the portion of those shares of Capital Stock or similar equity interests so
distributed applicable to one share of Common Stock and the denominator is the
Current Market Price per share of the Common Stock. Any adjustment to the
Settlement Rate and Early Settlement Rate under this Section 5.6(a)(4)(ii) will
occur at the earlier of (1) the tenth Trading Day from, and including, the
effective date of the Spin-Off and (2) the date of the securities being offered
in the Initial Public Offering of the Spin-Off, if that Initial Public Offering
is effected simultaneously with the Spin-Off.

                                       44
<PAGE>

         (5) Cash Distributions. In case the Company shall, (i) by dividend or
otherwise, distribute to all holders of its Common Stock cash (excluding any
cash that is distributed in a Reorganization Event to which Section 5.6(b)
applies or as part of a distribution referred to in Section 5.6(a)(4) in an
aggregate amount that, combined together with (ii) the aggregate amount of any
other distributions to all holders of its Common Stock made exclusively in cash
within the 12 months preceding the date of payment of such distribution and in
respect of which no adjustment pursuant to this Section 5.6(a)(5) or Section
5.6(a)(6) has been made and (iii) the aggregate of any cash plus the fair market
value as of the date of the expiration of the tender or exchange offer referred
to below (as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) of consideration payable in
respect of any tender or exchange offer by the Company or any of its
subsidiaries for all or any portion of the Common Stock concluded within the 12
months preceding the date of payment of the distribution described in clause (i)
above and in respect of which no adjustment pursuant to this Section 5.6(a)(5)
or Section 5.6(a)(6) of this Section has been made, exceeds 15% of the product
of the Current Market Price per share of the Common Stock on the date for the
determination of stockholders entitled to receive such distribution times the
number of shares of Common Stock outstanding on such date, then, and in each
such case, immediately after the close of business on such date for
determination, the Settlement Rate and Early Settlement Rate in effect at the
opening of business on the day following the date fixed for determination of the
stockholders entitled to receive such distribution shall be increased by
dividing such Settlement Rate or Early Settlement Rate, as applicable, by a
fraction, of which (A) the numerator shall be equal to the Current Market Price
per share of the Common Stock on the date fixed for such determination less an
amount equal to the quotient of (x) the combined amount distributed or payable
in the transactions described in clauses (i), (ii) and (iii) above and (y) the
number of shares of Common Stock outstanding on such date for determination and
(B) the denominator shall be equal to the Current Market Price per share of the
Common Stock on such date for determination.

         (6) Tender Offers. In case (i) a tender or exchange offer made by the
Company or any subsidiary of the Company for all or any portion of the Common
Stock shall expire and such tender or exchange offer (as amended upon the
expiration thereof) shall require the payment to stockholders (based on the
acceptance (up to any maximum specified in the terms of the tender or exchange
offer) of Purchased Shares) of an aggregate consideration having a fair market
value (as determined by the Board of Directors, whose determination shall be
conclusive and described in a Board Resolution) that combined together with (ii)
the aggregate of the cash plus the fair market value (as determined by the Board
of Directors, whose determination shall be conclusive and described in a Board
Resolution), as of the expiration of such tender or exchange offer, of
consideration payable in respect of any other tender or exchange offer, by the
Company or any subsidiary of the Company for all or any portion of the Common
Stock expiring within the 12 months preceding the expiration of such tender or
exchange offer and in respect of which no adjustment pursuant to Section
5.6(a)(5) or this Section 5.6(a)(6) has been made and (iii) the aggregate amount
of any distributions to all holders of the Company's Common Stock made
exclusively in cash within the 12 months preceding the expiration of such tender
or exchange offer and in respect of which no adjustment pursuant to Section
5.6(a)(5) or this Section 5.6(a)(6) has been made, exceeds 15% of the product of
the Current Market Price per share of the Common Stock as of the last time (the
"Expiration Time") tenders could have been made pursuant to such tender or
exchange offer (as it may be amended) times the number of shares of Common Stock
outstanding (including any tendered shares) at the Expiration Time, then, and in
each such case,

                                       45
<PAGE>

the Settlement Rate and Early Settlement Rate in effect at the
opening of business on the day following the date of the Expiration Time shall
be adjusted by dividing such Settlement Rate or Early Settlement Rate, as
applicable, by a fraction, of which (A) the numerator shall be equal to (x) the
product of (I) the Current Market Price per share of the Common Stock on the
date of the Expiration Time and (II) the number of shares of Common Stock
outstanding (including any tendered shares) at the Expiration Time less (y) the
amount of cash plus the fair market value (determined as aforesaid) of the
aggregate consideration payable to stockholders based on the transactions
described in clauses (i), (ii) and (iii) above (assuming in the case of clause
(i) the acceptance, up to any maximum specified in the terms of the tender or
exchange offer, of Purchased Shares), and (B) the denominator shall be equal to
the product of (x) the Current Market Price per share of the Common Stock as of
the Expiration Time and (y) the number of shares of Common Stock outstanding
(including any tendered shares) as of the Expiration Time less the number of all
shares validly tendered and not withdrawn as of the Expiration Time (the shares
deemed so accepted, up to any such maximum, being referred to as the "Purchased
Shares").

         (7) Reclassification. The reclassification of Common Stock into
securities including securities other than Common Stock (other than any
reclassification upon a Reorganization Event to which Section 5.6(b) applies)
shall be deemed to involve (i) a distribution of such securities other than
Common Stock to all holders of Common Stock (and the effective date of such
reclassification shall be deemed to be "the date fixed for the determination of
stockholders entitled to receive such distribution" and the "date fixed for such
determination" within the meaning of paragraph (4) of this Section), and (ii) a
subdivision, split or combination, as the case may be, of the number of shares
of Common Stock outstanding immediately prior to such reclassification into the
number of shares of Common Stock outstanding immediately thereafter (and the
effective date of such reclassification shall be deemed to be "the day upon
which such subdivision or split becomes effective" or "the day upon which such
combination becomes effective," as the case may be, and "the day upon which such
subdivision, split or combination becomes effective" within the meaning of
paragraph (3) of this Section).

         (8) "Current Market Price". The "Current Market Price" of the Common
Stock means:

         (a) on any day the average of the Sales Prices for the five consecutive
Trading Days preceding the earlier of the day preceding the day in question and
the day before the "ex date" with respect to the issuance or distribution
requiring computation;

         (b) in the case of any Spin-Off that is effected simultaneously with an
Initial Public Offering of the securities being distributed in the Spin-Off, the
Sale Price of the Common Stock on the Trading Day on which the Initial Public
Offering price of the securities being distributed in the Spin-Off is
determined; and

         (c) in the case of any other Spin-Off, the average of the Sale Prices
of the Common Stock over the first ten Trading Days after the effective date of
such Spin-Off.

For purposes of this paragraph, the term "ex date," when used with respect to
any issuance or distribution, shall mean the first date on which the Common
Stock trades regular way on the relevant exchange or in the relevant market
without the right to receive such issuance or distribution.

                                       46
<PAGE>

         (9) Calculation of Adjustments. All adjustments to the Settlement Rate
or Early Settlement Rate, as applicable, shall be calculated to the nearest
1/10,000th of a share of Common Stock (or if there is not a nearest 1/10,000th
of a share to the next lower 1/10,000th of a share). No adjustment in the
Settlement Rate or Early Settlement Rate, as applicable, shall be required
unless such adjustment would require an increase or decrease of at least one
percent therein; provided, that any adjustments which by reason of this
subparagraph are not required to be made shall be carried forward and taken into
account in any subsequent adjustment. If an adjustment is made to the Settlement
Rate or Early Settlement Rate, as applicable, pursuant to paragraph (1), (2),
(3), (4), (5), (6), (7) or (10) of this Section 5.6(a), an adjustment shall also
be made to the Applicable Market Value solely to determine which of clauses (i),
(ii) or (iii) of the definition of Settlement Rate or Early Settlement Rate, as
applicable, in Section 5.1(a) will apply on the Stock Purchase Date. Such
adjustment shall be made by multiplying the Applicable Market Value by a
fraction, the numerator of which shall be the Settlement Rate or Early
Settlement Rate, as applicable, immediately after such adjustment pursuant to
paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section 5.6(a) and
the denominator of which shall be the Settlement Rate or Early Settlement Rate,
as applicable, immediately before such adjustment; provided, that if such
adjustment to the Settlement Rate or Early Settlement Rate, as applicable, is
required to be made pursuant to the occurrence of any of the events contemplated
by paragraph (1), (2), (3), (4), (5), (7) or (10) of this Section 5.6(a) during
the period taken into consideration for determining the Applicable Market Value,
appropriate and customary adjustments shall be made to the Settlement Rate or
Early Settlement Rate, as applicable.

         (10) Increase of Settlement Rate. The Company may make such increases
in the Settlement Rate or Early Settlement Rate, as applicable, in addition to
those required by this Section, as it considers to be advisable in order to
avoid or diminish any income tax to any holders of shares of Common Stock
resulting from any dividend or distribution of stock or issuance of rights or
warrants to purchase or subscribe for stock or from any event treated as such
for income tax purposes or for any other reasons.

         (b) Adjustment for Consolidation, Merger or Other Reorganization Event.

         In the event of:

         (1) any consolidation or merger of the Company with or into another
Person (other than a merger or consolidation in which the Company is the
continuing corporation and in which the Common Stock outstanding immediately
prior to the merger or consolidation is not exchanged for cash, securities or
other property of the Company or another corporation),

         (2) any sale, transfer, lease or conveyance to another Person of the
property of the Company as an entirety or substantially as an entirety,

         (3) any statutory exchange of securities of the Company with another
Person (other than in connection with a merger or acquisition), or

         (4) any liquidation, dissolution or winding up of the Company other
than as a result of or after the occurrence of a Termination Event (any such
event, a "Reorganization Event"),

                                       47
<PAGE>

each share of Common Stock covered by each Purchase Contract forming a part of
an Equity Security Unit or Stripped Unit, as the case may be, immediately prior
to such Reorganization Event shall, after such Reorganization Event, be
converted for purposes of the Purchase Contract into the kind and amount of
securities, cash and other property receivable in such Reorganization Event
(without any interest thereon, and without any right to dividends or
distributions thereon which have a record date that is prior to the Stock
Purchase Date) per share of Common Stock by a holder of Common Stock that (i) is
not a Person with which the Company consolidated or into which the Company
merged or which merged into the Company or to which such sale or transfer was
made, as the case may be (any such Person, a "Constituent Person"), or an
Affiliate of a Constituent Person to the extent such Reorganization Event
provides for different treatment of Common Stock held by Affiliates of the
Company and non-Affiliates, and (ii) failed to exercise his rights of election,
if any, as to the kind or amount of securities, cash and other property
receivable upon such Reorganization Event (provided that if the kind or amount
of securities, cash and other property receivable upon such Reorganization Event
is not the same for each share of Common Stock held immediately prior to such
Reorganization Event by other than a Constituent Person or an Affiliate thereof
and in respect of which such rights of election shall not have been exercised
("Non-electing Share"), then for the purpose of this Section the kind and amount
of securities, cash and other property receivable upon such Reorganization Event
by each Non-electing Share shall be deemed to be the kind and amount so
receivable per share by a plurality of the Non-electing Shares). On the Stock
Purchase Date, the Settlement Rate then in effect will be applied to the value
on the Stock Purchase Date of such securities, cash or other property.

         In the event of such a Reorganization Event, the Person formed by such
consolidation, merger or exchange or the Person which acquires the assets of the
Company or, in the event of a liquidation or dissolution of the Company, the
Company or a liquidating trust created in connection therewith, shall execute
and deliver to the Agent an agreement supplemental hereto providing that the
Holder of each Outstanding Unit shall have the rights provided by this Section
5.6. Such supplemental agreement shall provide for adjustments which, for events
subsequent to the effective date of such supplemental agreement, shall be as
nearly equivalent as may be practicable to the adjustments provided for in this
Section. The above provisions of this Section shall similarly apply to
successive Reorganization Events.

         Section 5.7 Notice of Adjustments and Certain Other Events.

         (a) Whenever the Settlement Rate and the Early Settlement Rate are
adjusted as herein provided, the Company shall:

                  (i) forthwith compute the Settlement Rate, the Early
         Settlement Rate and the Applicable Market Value in accordance with
         Section 5.6 and prepare and transmit to the Agent an Officer's
         Certificate setting forth the Settlement Rate, the Early Settlement
         Rate and the Applicable Market Value, the method of calculation thereof
         in reasonable detail, and the facts requiring such adjustment and upon
         which such adjustment is based; and

                  (ii) within ten Business Days following an adjustment to the
         Settlement Rate and the Early Settlement Rate, pursuant to Section 5.6,
         provide a written notice to the Holders of the Equity Security Units
         and Stripped Units of the adjustment and a statement in reasonable
         detail setting forth the method by which the adjustment to the
         Settlement

                                       48
<PAGE>

         Rate, the Early Settlement Rate and the Applicable Market Value was
         determined and setting forth the adjusted Settlement Rate, the Early
         Settlement Rate and the Applicable Market Value.

         (b) The Agent shall not at any time be under any duty or responsibility
to any Holder of Equity Security Units and Stripped Units to determine whether
any facts exist which may require any adjustment of the Settlement Rate, the
Early Settlement Rate and the Applicable Market Value, or with respect to the
nature or extent or calculation of any such adjustment when made, or with
respect to the method employed in making the same. The Agent shall not be
accountable with respect to the validity or value (or the kind or amount) of any
shares of Common Stock, or of any securities or property, which may at any time
be issued or delivered with respect to any Purchase Contract; and the Agent
makes no representation with respect thereto. The Agent shall not be responsible
for any failure of the Company to issue, transfer or deliver any shares of
Common Stock pursuant to a Purchase Contract or to comply with any of the
duties, responsibilities or covenants of the Company contained in this Article.

         Section 5.8 Termination Event; Notice.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including the rights and obligations of Holders to
purchase Common Stock, shall immediately and automatically terminate, without
the necessity of any notice or action by any Holder, the Agent or the Company,
if, on or prior to the Stock Purchase Date, a Termination Event shall have
occurred. Upon and after the occurrence of a Termination Event, the Equity
Security Units shall thereafter represent the right to receive the Notes, the
Treasury Consideration or the Applicable Ownership Interests in the Treasury
Portfolio, as the case may be, forming a part of such Equity Security Units, and
the Stripped Units shall thereafter represent the right to receive the Treasury
Securities forming a part of such Stripped Units, in each case in accordance
with the provisions of Section 4.3 of the Pledge Agreement. Upon the occurrence
of a Termination Event, the Company shall promptly but in no event later than
two Business Days thereafter give written notice to the Agent, the Collateral
Agent and to the Holders, at their addresses as they appear in the applicable
Register.

         Section 5.9 Early Settlement.

         (a) Subject to and upon compliance with the provisions of this Section
5.9, a Holder may settle Purchase Contracts underlying Equity Security Units or
Stripped Units early ("Early Settlement") at any time from and after the date of
this Agreement (i) other than during the period that commences at 5:00 p.m., New
York City time, on May 5, 2005 and ends at 9:00 a.m., New York City time, on May
19, 2005 and during the period that commences at 5:00 p.m., New York City time,
on June 22, 2005 and ends at 9:00 a.m., New York City time, on July 6, 2005 and
(ii) not later than 11:00 a.m., New York City time, on the eleventh Business Day
immediately preceding the Stock Purchase Date. In order to exercise the right to
effect Early Settlement with respect to any Purchase Contracts, the Holder must
deliver to the Agent at the Corporate Trust Office:

                  (1) the form of "Election to Settle Early" set forth in
         Exhibit F hereto properly completed and executed (or if such Holder's
         Equity Security Units or Stripped Units are held in certificated form,
         the Certificate(s) evidencing the related Equity Security Units or

                                       49
<PAGE>

         Stripped Units, as the case may be, duly endorsed for transfer to the
         Company or in blank with the form of "Election to Settle Early" on the
         reverse thereof duly completed); and

                  (2) payment payable to the Company in immediately available
         funds in an amount (the "Early Settlement Amount") equal to:

                           (A) the product of (i) the Stated Amount of such
                  Equity Security Units or Stripped Units, as the case may be,
                  multiplied by (ii) the number of Purchase Contracts with
                  respect to which the Holder has elected to effect Early
                  Settlement, plus

                           (B) if such delivery is made with respect to any
                  Purchase Contracts during the period from the close of
                  business on any Record Date next preceding any Payment Date to
                  the opening of business on such Payment Date, an amount equal
                  to the Contract Adjustment Payments, if any, payable on such
                  Payment Date with respect to such Purchase Contracts; provided
                  that no payment shall be required pursuant to clause (B) of
                  this sentence if the Company shall have elected to defer the
                  Contract Adjustment Payments that would otherwise be payable
                  on such Payment Date;

and provided, further, that, at that time, if so required by the United States
federal securities laws, a registration statement is in effect and a prospectus
is available covering the shares of Common Stock to be delivered in respect of
the Purchase Contracts being settled. Except as provided in the immediately
preceding sentence and subject to Section 5.2(d), no payment or adjustment shall
be made upon Early Settlement of any Purchase Contract on any Contract
Adjustment Payments accumulated on such Purchase Contract or on account of any
dividends on the Common Stock issued upon such Early Settlement. If the
foregoing requirements are first satisfied with respect to Purchase Contracts
underlying any Equity Security Units or Stripped Units, as the case may be, not
later than 5:00 p.m., New York City time, on a Business Day, such day shall be
the "Early Settlement Date" with respect to such Equity Security Units or
Stripped Units, as the case may be, and if such requirements are first satisfied
after 5:00 p.m., New York City time, on a Business Day or on a day that is not a
Business Day, the "Early Settlement Date" with respect to such Equity Security
Units or Stripped Units, as the case may be, shall be the next succeeding
Business Day.

         (b) Holders of Equity Security Units that include Notes and Stripped
Units may effect Early Settlement only in units of 20 and integral multiples of
20. If a successful remarketing or a Tax Event Redemption has occurred, Holders
of Equity Security Units may effect Early Settlement pursuant to this Section
5.9 only in units of 400,000 and integral multiples of 400,000.

         (c) Upon Early Settlement of any Purchase Contract by the Holder of the
related Equity Security Units or Stripped Units, as the case may be, the Company
shall issue, and the Holder shall be entitled to receive, 2.0886 shares of
Common Stock for each Equity Security Unit or Stripped Unit on account of such
Purchase Contract (the "Early Settlement Rate"). The Early Settlement Rate shall
be adjusted in the same manner and at the same time as the Settlement Rate is
adjusted. As promptly as practicable after Early Settlement of Purchase
Contracts in accordance with the provisions of this Section 5.9, the Company
shall issue and shall deliver to the Agent at the Corporate Trust Office a
certificate or certificates or book-entry interest for the full number of

                                       50
<PAGE>

shares of Common Stock issuable upon such Early Settlement together with payment
in lieu of any fraction of a share, as provided in Section 5.12.

         (d) No later than the third Business Day after the applicable Early
Settlement Date the Company shall cause (i) the shares of Common Stock issuable
upon Early Settlement of Purchase Contracts to be issued and delivered, and (ii)
the related Pledged Notes, Pledged Treasury Consideration or Pledged Applicable
Ownership Interests in the Treasury Portfolio, in the case of Equity Security
Units, or the related Pledged Treasury Securities, in the case of Stripped
Units, to be released from the Pledge by the Collateral Agent and transferred,
in each case, to the Agent for delivery to the Holder thereof or the Holder's
designee.

         (e) Upon Early Settlement of any Purchase Contracts, and subject to
receipt of shares of Common Stock from the Company and the Pledged Notes,
Pledged Treasury Consideration, Pledged Applicable Ownership Interests in the
Treasury Portfolio or Pledged Treasury Securities, as the case may be, from the
Collateral Agent, as applicable, the Agent shall, in accordance with the
instructions provided by the Holder thereof on the applicable form of "Election
to Settle Early" (i) transfer to the Holder the Pledged Notes, Pledged Treasury
Consideration, Pledged Applicable Ownership Interests in the Treasury Portfolio
or Pledged Treasury Securities, as the case may be, forming a part of such
Equity Security Units or Stripped Units, as the case may be, and (ii) deliver to
the Holder a certificate or certificates or book-entry interest for the full
number of shares of Common Stock issuable upon such Early Settlement together
with payment in lieu of any fraction of a share, as provided in Section 5.12.

         (f) In the event that Early Settlement is effected with respect to
Purchase Contracts underlying less than all the Equity Security Units or
Stripped Units, as the case may be, evidenced by a Certificate, upon such Early
Settlement the Company shall execute and the Agent shall authenticate, execute
on behalf of the Holder thereof and deliver to the Holder thereof, at the
expense of the Company, a Certificate evidencing the Equity Security Units or
Stripped Units, as the case may be, as to which Early Settlement was not
effected.

         (g) Upon Early Settlement of any Purchase Contracts, Contract
Adjustment Payments that would otherwise be payable after the Early Settlement
Date with respect to such Purchase Contracts shall not be payable.

         Section 5.10 Early Settlement Upon Merger.

         (a) In the event of a merger or consolidation of the Company of the
type described in clause (1) of Section 5.6(b) in which the Common Stock
outstanding immediately prior to such merger or consolidation is exchanged for
consideration consisting of at least 30% cash or cash equivalents (any such
event a "Cash Merger"), then the Holder of each Equity Security Unit or Stripped
Unit, as the case may be, will have the right to settle the Purchase Contract
underlying such Equity Security Units or Stripped Units, as the case may be,
prior to the Stock Purchase Date ("Merger Early Settlement") as provided herein;
provided, however, that, at that time, if so required under the United States
federal securities laws, a registration statement is in effect and a prospectus
is available covering the shares of Common Stock to be delivered in respect of
the Purchase Contracts being settled. On or before the fifth Business Day after
the completion of a Cash Merger, the Company or, at the request and expense of
the Company, the Agent, shall give

                                       51
<PAGE>

all Holders notice of the occurrence of the Cash Merger and of the right of
Merger Early Settlement arising as a result thereof. The Company shall also
deliver a copy of such notice to the Agent and the Collateral Agent.

                   Each such notice shall contain:

                  (i) the date, which shall be not less than 20 nor more than 30
         calendar days after the date of such notice, on which the Merger Early
         Settlement will be effected (the "Merger Early Settlement Date");

                  (ii) the date, which shall be one Business Day immediately
         preceding the Merger Early Settlement Date, by which the Merger Early
         Settlement right must be exercised;

                  (iii) the Settlement Rate in effect as a result of such Cash
         Merger and the kind and amount of securities, cash and other property
         receivable by the Holder upon settlement of each Purchase Contract
         pursuant to Section 5.6(b);

                  (iv) a statement to the effect that all or a portion of the
         Purchase Price payable by the Holder to settle the Purchase Contract
         will be offset against the amount of cash so receivable upon exercise
         of Merger Early Settlement, as applicable; and

                  (v) the instructions a Holder must follow to exercise the
         Merger Early Settlement right.

         (b) To exercise a Merger Early Settlement right, a Holder shall deliver
to the Agent at the Corporate Trust Office not later than 5:00 p.m., New York
City time, on the date specified in the notice:

                  (1) the form of "Election to Settle Early" set forth in
         Exhibit F hereto properly completed and executed (or if such Holder's
         Equity Security Units or Stripped Units, as the case may be, are held
         in certificated form, the Certificate(s) evidencing the related Equity
         Security Units or Stripped Units, as the case may be, with respect to
         which the Merger Early Settlement right is being exercised duly
         endorsed for transfer to the Company or in blank with the form of
         "Election to Settle Early" on the reverse thereof duly completed; and

                  (2) payment payable to the Company in immediately available
         funds in an amount equal to the Early Settlement Amount; provided,
         that, to the extent that the merger consideration consists of cash or
         cash equivalents, the Company may provide (and so specify in the notice
         pursuant to Section 5.10(a)) that the Purchase Price payable per
         Purchase Contract will be offset against the amount of cash and cash
         equivalents that will be receivable by such Holder upon settlement of
         the Purchase Contracts as described in the notice to Holders in
         accordance with Section 5.10(a) (the Early Settlement Amount less the
         cash offset, if any, the "Merger Early Settlement Amount").

         (c) Holders of Equity Security Units that include Notes and Stripped
Units may effect Merger Early Settlement only in units of 20 and multiples of
20. If a successful remarketing or a

                                       52
<PAGE>

Tax Event Redemption has occurred, Holders of Equity Security Units may effect
Merger Early Settlement pursuant to this Section 5.10 only in units of 400,000
and integral multiples of 400,000.

         (d) On the Merger Early Settlement Date, the Company shall deliver or
cause to be delivered (i) the net cash, securities and other property to be
received by such exercising Holder, equal to the Settlement Rate as adjusted
pursuant to Section 5.6, in respect of the number of Purchase Contracts for
which such Merger Early Settlement right was exercised, and (ii) the related
Pledged Notes, Pledged Treasury Consideration or Pledged Applicable Ownership
Interests in the Treasury Portfolio, in the case of Equity Security Units, or
Pledged Treasury Securities, in the case of Stripped Units, to be released from
the Pledge by the Collateral Agent and transferred, in each case, to the Agent
for delivery to the Holder thereof or its designee.

         (e) Upon Merger Early Settlement of any Purchase Contracts, and subject
to receipt of such net cash, securities or other property from the Company and
the Pledged Notes, Pledged Treasury Consideration, Pledged Applicable Ownership
Interests in the Treasury Portfolio or Pledged Treasury Securities, as the case
may be, from the Collateral Agent, as applicable, the Agent shall, in accordance
with the instructions provided by the Holder thereof on the applicable form of
Election to Settle Early on the reverse of the Certificate evidencing the
related Equity Security Units or Stripped Units, as the case may be, (i)
transfer to the Holder the Pledged Notes, Pledged Treasury Consideration,
Pledged Applicable Ownership Interests in the Treasury Portfolio or Pledged
Treasury Securities, as the case may be, forming a part of such Equity Security
Units or Stripped Units, as the case may be, and (ii) deliver to the Holder such
net cash, securities or other property issuable upon such Merger Early
Settlement together with payment in lieu of any fraction of a share, as provided
in Section 5.12.

         (f) In the event that Merger Early Settlement is effected with respect
to Purchase Contracts underlying less than all the Equity Security Units or
Stripped Units, as the case may be, evidenced by a Certificate, upon such Merger
Early Settlement the Company (or the successor to the Company hereunder) shall
execute and the Agent shall authenticate, execute on behalf of the Holder
thereof and deliver to the Holder thereof, at the expense of the Company, a
Certificate evidencing the Equity Security Units or Stripped Units, as the case
may be, as to which Merger Early Settlement was not effected.

         (g) Upon Merger Early Settlement of any Purchase Contracts, Contract
Adjustment Payments that would otherwise be payable after the Merger Early
Settlement Date with respect to such Purchase Contracts shall not be payable.

         Section 5.11 Charges and Taxes.

         The Company will pay all stock transfer and similar taxes attributable
to the initial issuance and delivery of the shares of Common Stock pursuant to
the Purchase Contracts; provided, that the Company shall not be required to pay
any such tax or taxes which may be payable in respect of any exchange of or
substitution for a Certificate evidencing Equity Security Units or Stripped
Units or any issuance of a share of Common Stock in a name other than that of
the registered Holder of a Certificate surrendered in respect of the Equity
Security Units and Stripped Units evidenced thereby, other than in the name of
the Agent, as custodian for such Holder, and the Company shall not be required
to issue or deliver such share certificates or book-entry interest in Common
Stock

                                       53
<PAGE>

or Certificates unless and until the Person or Persons requesting the transfer
or issuance thereof shall have paid to the Company the amount of such tax or
shall have established to the satisfaction of the Company that such tax has been
paid.

         Section 5.12 No Fractional Shares.

         No fractional shares or scrip representing fractional shares of Common
Stock shall be issued or delivered upon settlement on the Stock Purchase Date or
upon Early Settlement or Merger Early Settlement of any Purchase Contracts. If
Certificates evidencing more than one Purchase Contract shall be surrendered for
settlement at one time by the same Holder, the number of full shares of Common
Stock which shall be delivered upon settlement shall be computed on the basis of
the aggregate number of Purchase Contracts evidenced by the Certificates so
surrendered. Instead of any fractional share of Common Stock which would
otherwise be deliverable upon settlement of any Purchase Contracts on the Stock
Purchase Date or upon Early Settlement or Merger Early Settlement, the Company,
through the Agent, shall make a cash payment in respect of such fractional share
in an amount equal to the value of such fractional share times the Closing Price
on the date of such settlement. The Company shall provide the Agent from time to
time with sufficient funds to permit the Agent to make all cash payments
required by this Section 5.12 in a timely manner.

         Section 5.13 Tax Treatment.

         The Company covenants and agrees and each Holder, by purchasing an
Equity Security Unit, agrees to:

                  (i) treat a Holder's acquisition of an Equity Security Unit as
         the acquisition of the Note and Purchase Contract constituting the
         Equity Security Unit;

                  (ii) treat a Holder's ownership of Stripped Units as the
         ownership of the Treasury Securities and Purchase Contracts
         constituting the Stripped Units;

                  (iii) treat each Holder as the owner of the applicable
         interest in the Collateral Account, including the Note, Treasury
         Consideration, Applicable Ownership Interest in the Treasury Portfolio
         or Treasury Securities, as the case may be; and

                  (iv) allocate the purchase price of each Equity Security Unit
         between the Note and Purchase Contract as $50 and $0, respectively.

         Section 5.14 ERISA.

         Each Holder, by purchasing an Equity Security Unit or Stripped Unit,
represents and warrants on each day from and including the date of its
acquisition of the Equity Security Unit or Stripped Unit through and including
the date of the satisfaction of the obligations under the Purchase Contract
and/or the disposition of such Equity Security Unit or Stripped Unit that either
(i) no portion of the assets used by such Holder to acquire the Equity Security
Unit or Stripped Unit constitutes the assets of any Plan or (ii) the
acquisition, holding and disposition of the Equity Security Unit or Stripped
Unit by such Holder does not and will not constitute a non-exempt

                                       54
<PAGE>

prohibited transaction under ERISA or Section 4975 of the Code or a violation of
any Similar Laws.

                                    REMEDIES

         Section 6.1 Unconditional Right of Holders to Purchase Common Stock.

         (a) The Holder of any Equity Security Units or Stripped Units, as the
case may be, shall have the right, which is absolute and unconditional, subject
to the right of the Company to defer payment thereof pursuant to Section 5.3,
and to the forfeiture of any Deferred Contract Adjustment Payments upon Early
Settlement pursuant to Section 5.9(a), upon Merger Early Settlement pursuant to
Section 5.10 or upon the occurrence of a Termination Event, to receive payment
of each installment of the Contract Adjustment Payments, if any, with respect to
the Purchase Contracts constituting a part of such Equity Security Units or
Stripped Units, as the case may be, on the respective Payment Dates for such
Equity Security Units or Stripped Units, as the case may be, and

         (b) Subject to Sections 5.6 and 5.8, the Holder of any Equity Security
Units or Stripped Units, as the case may be, shall have the right, which is
absolute and unconditional, to purchase Common Stock pursuant to the Purchase
Contract constituting a part of such Equity Security Units or Stripped Units and
to institute suit for the enforcement of any such right to purchase Common
Stock, and such right shall not be impaired without the consent of such Holder.

         Section 6.2 Restoration of Rights and Remedies.

         If any Holder has instituted any proceeding to enforce any right or
remedy under this Agreement and such proceeding has been discontinued or
abandoned for any reason, or has been determined adversely to such Holder, then
and in every such case, subject to any determination in such proceeding, the
Company and such Holder shall be restored severally and respectively to their
former positions hereunder and thereafter all rights and remedies of such Holder
shall continue as though no such proceeding had been instituted.

         Section 6.3 Rights and Remedies Cumulative.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Certificates in Section 3.10(f), no
right or remedy herein conferred upon or reserved to the Holders is intended to
be exclusive of any other right or remedy, and every right and remedy shall, to
the extent permitted by law, be cumulative and in addition to every other right
and remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

         Section 6.4 Delay or Omission Not Waiver.

         No delay or omission of any Holder to exercise any right or remedy upon
a default shall impair any such right or remedy or constitute a waiver of any
such right. Every right and remedy

                                       55
<PAGE>
given by this Article or by law to the Holders may be exercised from time to
time, and as often as may be deemed expedient, by such Holders.

         Section 6.5 Undertaking For Costs.

         All parties to this Agreement agree, and each Holder of Equity Security
Units or Stripped Units, as the case may be, by its acceptance of such Equity
Security Units or Stripped Units, as the case may be, shall be deemed to have
agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Agreement, or in any suit against
the Agent for any action taken, suffered or omitted by it as Agent, the filing
by any party litigant in such suit of an undertaking to pay the costs of such
suit, and that such court may in its discretion assess reasonable costs,
including reasonable attorneys' fees and expenses, against any party litigant in
such suit, having due regard to the merits and good faith of the claims or
defenses made by such party litigant; provided that the provisions of this
Section shall not apply to any suit instituted by the Company, to any suit
instituted by the Agent, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% of the Outstanding Units, or to
any suit instituted by any Holder for the enforcement of distributions on any
Notes or any Purchase Contract on or after the respective Payment Date therefor
in respect of any Equity Security Units or Stripped Units, as the case may be,
held by such Holder, or for enforcement of the right to purchase shares of
Common Stock under the Purchase Contract constituting part of any Equity
Security Units or Stripped Units, as the case may be, held by such Holder.

         Section 6.6 Waiver of Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants in or the
performance of this Agreement; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, but will suffer and permit the execution of every power of the Agent and
the Holders as though no such law had been enacted.

                                  ARTICLE VII.

genuineness, enforceability or sufficiency of any Transaction Document (other
than as against the Agent) or the Equity Security Units or Stripped Units or any
other document referred to or provided for herein or therein or for any failure
by the Company, any Holder or any other Person (except the Agent) to perform any
of its obligations hereunder or thereunder or for the perfection, priority or,
except as expressly required hereby, existence, validity, perfection or
maintenance of any security interest created under the Pledge Agreement, or for
the use or application by the Company of the proceeds in respect of the Purchase
Contracts;

         (5) shall not be required to initiate or conduct any litigation or

Equity Security Units or Stripped Units or other rights under any Transaction
Document.

         (b) No provision of any Transaction Document shall be construed to
relieve the Agent from liability for its own negligent action, its own negligent
failure to act, its own bad faith, or its own willful misconduct, except that:

         (1) this paragraph (b) shall not be construed to limit the effect of
paragraph (a) of this Section;

         (2) the Agent shall not be liable for any error of judgment made in
good faith by a Responsible Officer, unless it shall be proved that the Agent
was grossly negligent in ascertaining the pertinent facts; and

funds or otherwise incur any financial liability in the performance of any of
its duties hereunder.

         Any Registrar or any other agent of the Company, or the Agent and its
Affiliates, in their individual or any other capacity, may become the owner or

the Agent. The Agent and its Affiliates may (without having to account therefor
to the Company or any Holder of Equity Security Units or Stripped Units or

investments in and generally engage in any kind of banking, trust or other
business with the Company, any Holder of Equity Security Units or Stripped Units
and any holder of Separate Notes (and any of their respective subsidiaries or
Affiliates) as if it were not acting as the Agent and the Agent and its
Affiliates may accept fees and other consideration from the Company, any Holder

without having to account for the same to any such Person.

         Section 7.6 Money Held In Custody.

in writing between the Company and the Agent;

         (b) reimburse the Agent upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Agent in accordance with any
provision of this Agreement or the other Transaction Documents (including the
reasonable compensation and the reasonable expenses and disbursements of its
agents and counsel), except any such expense, disbursement or advance as may be
attributable to its gross negligence, willful misconduct or bad faith; and

         (c) indemnify the Agent for, and to hold it harmless against, any loss,
liability or reasonable out-of-pocket expense incurred without gross negligence,
willful misconduct or bad faith on its part, arising out of or in connection
with the acceptance or administration of its duties under the other Transaction
Documents, including the costs and expenses (including reasonable fees and

which may give rise to the indemnity hereunder and give the Company the
opportunity to participate in the defense of such claim with counsel reasonably
satisfactory to the indemnified party, and no such claim shall be settled
without the written consent of the Company, which consent shall not be
unreasonably withheld, provided that any failure to give any such notice shall
not affect the obligation of the Company under this Section. The

                                       60
<PAGE>

provisions of this Section 7.7 shall survive the termination of any and all
Transaction Documents, the satisfaction or discharge of the Equity Security
Units or Stripped Units and/ or the Separate Notes or the resignation or removal
of the Agent.

         Section 7.8 Corporate Agent Required; Eligibility.

         There shall at all times be an Agent hereunder which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws to exercise corporate trust powers, having (or being a member of a bank
holding company having) a combined capital and surplus of at least $50,000,000,
subject to supervision or examination by federal or state authority and having
(or being a member of a bank holding company having) a Corporate Trust Office in
the Borough of Manhattan, the City of New York, if there be such a corporation,
qualified and eligible under this Article and willing to act on reasonable
terms. If such corporation publishes reports of condition at least annually,
pursuant to law or to the requirements of said supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such corporation shall be deemed to be its combined capital and
surplus as set forth in its most recent report of condition so published. If at
any time the Agent shall cease to be eligible in accordance with the provisions
of this Section, it shall resign immediately in the manner and with the effect
hereinafter specified in this Article.

         Section 7.9 Resignation and Removal; Appointment of Successor.

         (a) No resignation or removal of the Agent and no appointment of a
successor Agent pursuant to this Article shall become effective until the
acceptance of appointment by the successor Agent in accordance with the
applicable requirements of Section 7.10.

         (b) The Agent may resign at any time by giving written notice thereof
to the Company 60 days prior to the effective date of such resignation. If the
instrument of acceptance by a successor Agent required by Section 7.10 shall not
have been delivered to the Agent within 30 days after the giving of such notice
of resignation, the resigning Agent may petition, at the expense of the Company,
any court of competent jurisdiction for the appointment of a successor Agent.

         (c) The Agent may be removed at any time by Act of the Holders of a
majority in number of the Outstanding Units upon delivery of a written notice to
the Agent and the Company. If the instrument of acceptance by a successor Agent
required by Section 7.10 shall not have been delivered to the Agent within 30
days after the giving of such notice of removal, the Agent to be removed may
petition, at the expense of the Company, any court of competent jurisdiction for
the appointment of a successor Agent.

         (d) If at any time:

         (1) the Agent has a "conflicting interest" (as defined in Section
310(b) of the TIA) and fails to eliminate the conflicting interest or resign
pursuant to Section 310(b) of the TIA upon written request therefor by the
Company or by any Holder who has been a bona fide Holder of an Equity Security
Unit or a Stripped Unit for at least six months, as if this Agreement were an
indenture qualified under the TIA; or

                                       61
<PAGE>

         (2) the Agent shall cease to be eligible under Section 7.8 and shall
fail to resign after written request therefor by the Company or by any such
Holder; or

         (3) the Agent shall become incapable of acting or shall be adjudged a
bankrupt or insolvent or a receiver of the Agent or of its property shall be
appointed or any public officer shall take charge or control of the Agent or of
its property or affairs for the purpose of rehabilitation, conservation or
liquidation;

then, in any such case, (x) the Company by a Board Resolution may remove the
Agent, or (y) any Holder who has been a bona fide Holder of Equity Security
Units or Stripped Equity Units for at least six months may, on behalf of himself
and all others similarly situated, petition any court of competent jurisdiction
for the removal of the Agent and the appointment of a successor Agent.

         (e) If the Agent shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Agent for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Agent and
shall comply with the applicable requirements of Section 7.10. If no successor
Agent shall have been so appointed by the Company and accepted appointment in
the manner required by Section 7.10, any Holder who has been a bona fide Holder
of Equity Security Units or Stripped Equity Units for at least six months may,
on behalf of himself and all others similarly situated, petition any court of
competent jurisdiction for the appointment of a successor Agent.

         (f) The Company shall give, or shall cause such successor Agent to
give, notice of each resignation and each removal of the Agent and each
appointment of a successor Agent by mailing written notice of such event by
first-class mail, postage prepaid, to all Holders as their names and addresses
appear in the applicable Register. Each notice shall include the name of the
successor Agent and the address of its Corporate Trust Office.

         Section 7.10 Acceptance of Appointment by Successor.

         (a) In case of the appointment hereunder of a successor Agent, every
such successor Agent so appointed shall execute, acknowledge and deliver to the
Company and to the retiring Agent an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Agent shall become
effective and such successor Agent, without any further act, deed or conveyance,
shall become vested with all the rights, powers, agencies, trusts and duties of
the retiring Agent; but, on the request of the Company or the successor Agent,
such retiring Agent shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Agent all the rights, powers,
agencies, trusts and duties of the retiring Agent and duly assign, transfer and
deliver to such successor Agent all property and money held by such retiring
Agent hereunder.

         (b) Upon request of any such successor Agent, the Company shall execute
any and all instruments for more fully and certainly vesting in and confirming
to such successor Agent all such rights, powers, agencies, trusts and duties
referred to in paragraph (a) of this Section.

         (c) No successor Agent shall accept its appointment unless at the time
of such acceptance such successor Agent shall be qualified and eligible under
this Article.

         Section 7.11 Merger, Conversion, Consolidation or Succession to
Business.

         Any corporation into which the Agent may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Agent shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Agent, shall be the successor of the Agent hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Certificates shall have been
authenticated and executed on behalf of the Holders, but not delivered, by the
Agent then in office, any successor by merger, conversion or consolidation to
such Agent shall adopt such authentication and execution and deliver the
Certificates so authenticated and executed with the same effect as if such
successor Agent had itself authenticated and executed such Equity Security Units
and Stripped Units.

         Section 7.12 Preservation of Information; Communications to Holders.

         (a) The Agent shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders received by the Agent in its
capacity as Registrar.

         (b) If three or more Holders (herein referred to as "Applicants") apply
in writing to the Agent, and furnish to the Agent reasonable proof that each
such applicant has owned Equity Security Units or Stripped Units, as the case
may be, for a period of at least six months preceding the date of such
application, and such application states that the Applicants desire to
communicate with other Holders with respect to their rights under this Agreement
or under the Equity Security Units or Stripped Units, as the case may be, and is
accompanied by a copy of the form of proxy or other communication which such
Applicants propose to transmit, then the Agent shall mail to all the Holders
copies of the form of proxy or other communication which is specified in such
request, with reasonable promptness after a tender to the Agent of the materials
to be mailed and of payment, or provision, in the absence of bad faith,
satisfactory to the Agent for the payment, of the reasonable expenses of such
mailing.

         Section 7.13 Failure to Act.

         In the event of any ambiguity in the provisions of any Transaction
Document or any dispute between or conflicting claims by or among the parties
hereto or any other Person, the Agent shall be entitled, after prompt notice to
the Company and the Holders of Equity Security Units and Stripped Units, at its
sole option, to refuse to comply with any and all such claims, demands or
instructions so long as such dispute or conflict shall continue, and the Agent
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 Agent 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, reasonably satisfactory to the Agent, or (ii)
the Agent shall have received security or an indemnity reasonably satisfactory
to the Agent sufficient to save the Agent harmless from and against any and all
loss, liability or reasonable out-of-pocket expense which the Agent may incur by
reason of its acting without bad faith, willful misconduct or gross negligence.
The Agent may in addition elect to commence an interpleader action or seek other
judicial relief or

                                       63
<PAGE>

orders as the Agent may deem necessary. Notwithstanding anything contained
herein to the contrary, the Agent shall not be required to take any action that
is in its opinion contrary to law or to the terms of any Transaction Document,
or which would in its opinion subject it or any of its officers, employees or
directors to liability.

         Section 7.14 No Obligations of Agent.

         Except to the extent otherwise provided in this Agreement, the Agent
assumes no obligation and shall not be subject to any liability under this
Agreement, the Pledge Agreement or any Purchase Contract in respect of the
obligations of the Holder of any Equity Security Units or Stripped Units
thereunder. The Company agrees, and each Holder of a Certificate, by such
Holder's acceptance thereof, shall be deemed to have agreed, that the Agent's
execution of the Certificates on behalf of the Holders shall be solely as agent
and attorney-in-fact for the Holders, and that the Agent shall have no
obligation to perform such Purchase Contracts on behalf of the Holders, except
to the extent expressly provided in Article V. Anything contained in this
Agreement to the contrary notwithstanding, in no event shall the Agent or its
officers, employees or agents be liable 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 Agent and regardless of the form of action.

         Section 7.15 Tax Compliance.

         (a) The Agent, on its own behalf and on behalf of the Company, will
comply with all applicable certification, information reporting and withholding
(including "backup" withholding) requirements imposed on it as a paying agent by
applicable tax laws, regulations or administrative practice with respect to any
payments made with respect to the Equity Security Units and Stripped Units. Such
compliance shall include, without limitation, the preparation and timely filing
of required returns and the timely payment of all amounts required to be
withheld to the appropriate taxing authority or its designated agent.

         (b) The Agent shall comply with any reasonable written direction timely
received from the Company with respect to the application of such requirements
to particular payments to Holders or in other particular circumstances, and may
for purposes of this Agreement rely on any such direction in accordance with
Section 7.1(a)(2).

         (c) The Agent shall maintain all appropriate records documenting
compliance with such requirements, and shall make such records available, on
written request, to the Company or its authorized representative within a
reasonable period of time after receipt of such request.

                                 ARTICLE VIII.

Agent, the Company (when authorized by a Board Resolution) and the Agent may
enter into one or more agreements supplemental hereto, in form satisfactory to
the Company and the Agent, for the purpose of modifying in any manner the terms
of the Purchase Contracts or the provisions of this Agreement or the rights of
the Holders in respect of the Equity Security Units and Stripped Units;
provided, however, that, no such supplemental agreement shall, without the

together as one class):

Stripped Units the consent of whose Holders is required for any such
supplemental agreement;

provided, that if any amendment or proposal referred to above would adversely
affect only the Equity Security Units or the Stripped Units, 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; provided
further, however, that no agreement, whether with or without the consent of
Holders shall affect Section 3.16.

         (b) It shall not be necessary for any Act of Holders under this Section

         Section 10.1 Performance Under Purchase Contracts and this Agreement.

         The Company covenants and agrees for the benefit of the Holders from
time to time of the Equity Security Units and Stripped Units that it will duly
and punctually perform its obligations under the Purchase Contracts in
accordance with the terms of the Purchase Contracts and this Agreement. In the
case of Early Settlement pursuant to Section 5.9 or Merger Early Settlement
pursuant to Section 5.10, if the United States federal securities laws so
require, the Company will use commercially reasonable efforts to (i) have in
effect a registration statement covering the shares of Common Stock to be
delivered in respect of the Purchase Contracts being settled and (ii) provide a
prospectus in connection therewith, in each case that may be used in connection
with such Early Settlement or Merger Early Settlement. In addition, if required
by applicable law, the Company will use commercially reasonable efforts to
ensure that a registration statement covering the full amount of the Notes to be
remarketed on the Initial Remarketing Date or any Subsequent Remarketing Date
shall be effective in a form that will enable the Remarketing Agent to rely on
it in connection with one or more remarketings, as necessary.

         Section 10.2 Maintenance of Office or Agency.

         (a) The Company will maintain in the Borough of Manhattan, The City of
New York an office or agency where Certificates may be presented or surrendered
for payment of Contract Adjustment Payments, acquisition of shares of Common
Stock upon settlement of the Purchase Contracts on any Settlement Date and for
transfer of Collateral upon occurrence of a Termination Event, where
Certificates may be surrendered for registration of transfer or exchange, for a
Collateral Substitution or recreation of Equity Security Units and where notices
and demands to or upon the Company in respect of the Equity Security Units and
Stripped Units and this Agreement may be served. The Company will give prompt
written notice to the Agent of the location, and any change in the location, of
such office or agency. If at any time the Company shall fail to maintain any
such required office or agency or shall fail to furnish the Agent with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office, Office of the Agent in The City of New
York, and the Company hereby appoints the Agent as its agent to receive all such
presentations, surrenders, notices and demands.

         (b) The Company may also from time to time designate one or more other
offices or agencies where Certificates may be presented or surrendered for any
or all such purposes and may from time to time rescind such designations;
provided, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the

                                       68
<PAGE>

Borough of Manhattan, The City of New York for such purposes. The Company will
give prompt written notice to the Agent of any such designation or rescission
and of any change in the location of any such other office or agency. The

the Agent at the Office of the Agent in The City of New York as paying agent in
such city.

         Section 10.3 Company to Reserve Common Stock.

         The Company shall at all times prior to the Stock Purchase Date reserve
and keep available, free from preemptive rights, out of its authorized but

the Equity Security Units and Stripped Units evidenced by outstanding
Certificates.

         Section 10.4 Covenants as to Common Stock.

         The Company covenants that all shares of Common Stock which may be
issued against tender of payment in respect of any Purchase Contract
constituting a part of the Outstanding Units will, upon issuance, be duly
authorized, validly issued, fully paid and nonassessable.

         Section 10.5 Statements of Officer of the Company as to Default.

         The Company will deliver to the Agent, within 120 days after the end of
each fiscal year of the Company ending after the date hereof, an Officer's
Certificate, stating whether or not to the best knowledge of the signer thereof
the Company is in default in the performance and observance of any of the terms,
provisions and conditions hereof, and if the Company shall be in default,
specifying all such defaults and the nature and status thereof of which such
officer may have knowledge.

         City time, on a Business Day, then such payment shall be made no later
         than 9:30 a.m., New York City time, on the next succeeding Business
         Day) and

                  (ii) in the case of payments in respect of any Pledged Notes,

Pledged Notes, Pledged Treasury Consideration or Pledged Applicable Ownership
Interests in the Treasury Portfolio, as the case may be, pledged to secure the

             (Form of Reverse of Equity Security Units Certificate)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of June 26, 2002 (as may be amended or supplemented
from time to time, the "Purchase Contract Agreement"), between the Company and
JPMorgan Chase Bank, as Purchase Contract Agent (including its successors
thereunder, herein called the "Agent"), to which Purchase Contract Agreement and
supplemental agreements thereto reference is hereby made for a description of
the respective rights, limitations of rights, obligations, duties and immunities
thereunder of the Agent, the Company, and the Holders and of the terms upon
which the Equity Security Units Certificates are executed and delivered.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Equity Security Units Certificate to purchase, and the Company to sell, on the
Stock Purchase Date at a price equal to $50 (the "Purchase Price"), a number of
shares of Common Stock of the Company equal to the Settlement Rate, unless, on
or prior to the Stock Purchase Date, there shall have occurred a Termination
Event with respect to the Equity Security Units of which such Purchase Contract
is a part. The "Settlement Rate" is equal to:

                  (a) if the Applicable Market Value (as defined below) is
         greater than or equal to $23.94 (the "Threshold Appreciation Price"),
         2.0886 shares of Common Stock per Purchase Contract;

                  (b) if the Applicable Market Value is less than the Threshold
         Appreciation Price but is greater than $19.95 (the "Reference Price"),
         the number of shares of Common Stock per Purchase Contract equal to the
         Stated Amount of the related Equity Security Units divided by the
         Applicable Market Value; and

                  (c) if the Applicable Market Value is less than or equal to
         the Reference Price, 2.5063 shares of Common Stock per Purchase
         Contract,

in each case subject to adjustment as provided in the Purchase Contract
Agreement (and in each case rounded upward or downward to the nearest 1/10,000th
of a share).

         No fractional shares of Common Stock will be issued upon settlement of
Purchase Contracts, as provided in the Purchase Contract Agreement.

         The "Applicable Market Value" means the average of the Closing Price
per share of Common Stock on each of the 20 consecutive Trading Days ending on
the third Trading Day immediately preceding the Stock Purchase Date; provided,
that, in the case of a Merger Early Settlement, the 20 consecutive Trading Days
shall end on the date of completion of the Cash Merger.

         The "Closing Price" of the Common Stock on any date of determination
means the closing sale price (or, if no closing price is reported, the last
reported sale price) of the Common Stock on the New York Stock Exchange (the
"NYSE") on such date or, if the Common Stock is not listed for trading on the
NYSE on any such date, as reported in the composite transactions for the
principal United States securities exchange on which the Common Stock is so
listed, or if the Common Stock is not so listed on a United States national or
regional securities exchange, as

                                      A-6
<PAGE>

reported by the NASDAQ Stock Market, or, if the Common Stock is not so reported,
the last quoted bid price for the Common Stock in the over-the-counter market as
reported by the National Quotation Bureau or similar organization, or, if such
bid price is not available, the market value of the Common Stock on such date as
determined by a nationally recognized independent investment banking firm
retained for this purpose by the Company.

         A "Trading Day" means a day on which the Common Stock (A) is not
suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of the Common Stock.

         Each Purchase Contract evidenced hereby may be settled prior to the
Stock Purchase Date through Early Settlement or Merger Early Settlement. Each
Purchase Contract evidenced hereby which is settled either through Early
Settlement or Merger Early Settlement shall obligate the Holder of the related
Equity Security Unit to purchase at the Purchase Price, and the Company to sell,
a number of newly issued shares of Common Stock equal to the Early Settlement
Rate (in the case of an Early Settlement) or the applicable Settlement Rate (in
the case of a Merger Early Settlement).

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Equity Security Units Certificate shall pay the Purchase Price
for the shares of Common Stock purchased pursuant to each Purchase Contract
evidenced hereby:

                  (i) by effecting a Cash Settlement, Early Settlement or Merger
         Early Settlement;

                  (ii) by application of cash received in respect of the Pledged
         Treasury Consideration acquired from the proceeds of the successful
         remarketing of the related Pledged Notes underlying the Equity Security
         Units represented by this Equity Security Units Certificate;

                  (iii) if a Tax Event Redemption has occurred prior to the date
         of the successful remarketing of the Notes, by application of cash
         received in respect of the Pledged Applicable Ownership Interest (as
         specified in clause (A) of the definition of Applicable Ownership
         Interest) in the Treasury Portfolio purchased by the Collateral Agent
         on behalf of the Holder of this Equity Security Units Certificate; or

                  (iv) upon the occurrence of the Last Failed Remarketing, by
         the retention by the Company of the Pledged Note underlying the Equity
         Security Units represented by this Equity Security Units Certificate.

         If, as provided in the Purchase Contract Agreement, upon the occurrence
of the Last Failed Remarketing, the Collateral Agent, for the benefit of the
Company, exercises its rights as a secured creditor with respect to the Pledged
Notes related to this Equity Security Units Certificate, any accrued and unpaid
interest on such Pledged Notes will become payable by the Company to the Holder
of this Equity Security Units Certificate in the manner provided for in the
Purchase Contract Agreement.

                                      A-7

         The Company shall not be obligated to issue any shares of Common Stock
in respect of a Purchase Contract or deliver any certificates or book-entry
interest therefor to the Holder unless it shall have received payment in full of
the aggregate Purchase Price for the shares of Common Stock to be purchased
thereunder in the manner herein set forth, which payment, in the case of Equity
Security Units upon the occurrence of the Last Failed Remarketing, shall occur
by the resale or retention and cancellation of such Pledged Notes.

         Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the Pledged
Notes, but only to the extent instructed by the Holders as described below. Upon
receipt of notice of any meeting at which holders of Notes are entitled to vote
or upon the solicitation of consents, waivers or proxies of holders of Notes,
the Agent shall, as soon as practicable thereafter, mail to the Holders of
Equity Security Units a notice:

                  (a) containing such information as is contained in the notice
         or solicitation,

                  (b) stating that each such Holder on the record date set by
         the Agent therefor (which, to the extent possible, shall be the same
         date as the record date for determining the holders of Notes entitled
         to vote) shall be entitled to instruct the Agent as to the exercise of
         the voting rights pertaining to the Pledged Notes constituting a part
         of such Holder's Equity Security Units and

                  (c) stating the manner in which such instructions may be
         given.

Upon the written request of the Holders of Equity Security Units on such record
date received by the Agent at least six days prior to such meeting, the Agent
shall endeavor insofar as practicable to vote or cause to be voted, in
accordance with the instructions set forth in such requests, the maximum
aggregate principal amount of Pledged Notes as to which any particular voting
instructions are received. In the absence of specific instructions from the
Holder of an Equity Security Unit, the Agent shall abstain from voting the
Pledged Note evidenced by such Equity Security Unit.

         The Equity Security Units Certificates are issuable only in registered
form and only in denominations of a single Equity Security Unit and any integral
multiple thereof. The transfer of any Equity Security Units Certificate will be
registered and Equity Security Units Certificates may be exchanged as provided
in the Purchase Contract Agreement. The Equity Security Units Registrar may
require a Holder, among other things, to furnish appropriate endorsements and
transfer documents permitted by the Purchase Contract Agreement. No service
charge shall be required for any such registration of transfer or exchange, but
the Company and the Agent may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

         A Holder of Equity Security Units may substitute for the Pledged Notes
securing its obligations under the related Purchase Contracts Treasury
Securities in accordance with the terms of, and subject to the limitations set
forth in, the Purchase Contract Agreement and the Pledge Agreement. Holders may
make Collateral Substitutions only in integral multiples of 20 Equity Security
Units. From and after such Collateral Substitution, the Units for which such
Pledged

                                      A-8
<PAGE>

Treasury Securities secure the Holder's obligation under the Purchase Contract
shall be referred to as "Stripped Units." A Holder that elects to substitute a
Treasury Security for Pledged Notes thereby creating Stripped Units, shall be
responsible for any fees or expenses payable in connection therewith. Except as
provided in the Purchase Contract Agreement, for so long as the Purchase
Contract underlying an Equity Security Unit remains in effect, the rights and
obligations of the Holder of such Equity Security Unit in respect of the Pledged
Note, Pledged Treasury Consideration or Pledged Applicable Ownership Interest in
the Treasury Portfolio, as the case may be, and Purchase Contract constituting
such Equity Security Unit may be transferred and exchanged only as an Equity
Security Unit.

         A Holder of Stripped Units may recreate Equity Security Units by
delivering to the Collateral Agent Notes in exchange for the release of the
Pledged Treasury Securities in accordance with the terms of, and subject to the
limitations set forth in, the Purchase Contract Agreement and the Pledge
Agreement.

         Subject to the next succeeding paragraph, the Company shall pay on each
Payment Date, the Contract Adjustment Payments, if any, payable in respect of
each Purchase Contract to the Person in whose name the Equity Security Units
Certificate evidencing such Purchase Contract is registered at the close of
business on the Record Date for such Payment Date. Contract Adjustment Payments,
if any, will be payable at the office of the Agent in the City of New York or,
at the option of the Company, by check mailed to the address of the Person
entitled thereto at such address as it appears on the Equity Security Units
Register or by wire transfer to the account designated by such Person in writing
at least five Business Days prior to the applicable Payment Date.

         The Company shall have the right, at any time prior to the Stock
Purchase Date, to defer the payment of any or all of the Contract Adjustment
Payments otherwise payable on any Payment Date, but only if the Company shall
give the Holders and the Agent written notice of its election to defer Contract
Adjustment Payments as provided in the Purchase Contract Agreement. Any Contract
Adjustment Payments so deferred shall, to the extent permitted by law, bear
additional Contract Adjustment Payments thereon at the rate of 6.14% per year
(computed on the basis of a 360-day year of twelve 30-day months), compounding
on each succeeding Payment Date, until paid in full (such deferred installments
of Contract Adjustment Payments, if any, together with the additional Contract
Adjustment Payments, if any, accrued thereon, are referred to herein as the
"Deferred Contract Adjustment Payments"). Deferred Contract Adjustment Payments,
if any, shall be due on the next succeeding Payment Date except to the extent
that payment is deferred pursuant to the Purchase Contract Agreement. No
Contract Adjustment Payments may be deferred to a date that is after the Stock
Purchase Date and no such deferral period may end other than on a Payment Date.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments on the Purchase Contracts until a Payment Date prior to the
Stock Purchase Date, then all Deferred Contract Adjustment Payments, if any,
shall be payable to the registered Holders as of the close of business on the
Record Date immediately preceding such Payment Date.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments on the Purchase Contracts until the Stock Purchase Date, the
Company may elect to pay

                                      A-9
<PAGE>

each Holder on the Stock Purchase Date in respect of the Deferred Contract
Adjustment Payments, in lieu of a cash payment, a number of shares of Common
Stock (in addition to the number of shares of Common Stock equal to the
Settlement Rate) equal to (A) the aggregate amount of Deferred Contract
Adjustment Payments payable to such Holder (net of any required tax withholding
on such Deferred Contract Adjustment Payments, which shall be remitted to the
appropriate taxing jurisdiction) divided by (B) the Applicable Market Value.

         In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments then, until the Deferred Contract Adjustment
Payments have been paid, the Company shall not declare or pay dividends on, make
distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of its Common Stock other than:

                  (i) purchases, redemptions or acquisitions of shares of Common
         Stock in connection with any employment contract, benefit plan or other
         similar arrangement with or for the benefit of employees, officers or
         directors or a stock purchase or dividend reinvestment plan, or the
         satisfaction by the Company of its obligations pursuant to any contract
         or security outstanding on the date the Company exercises its rights to
         defer the Contract Adjustment Payments;

                  (ii) as a result of a reclassification of the Company's
         Capital Stock or the exchange or conversion of one class or series of
         the Company's Capital Stock for another class or series of the
         Company's Capital Stock;

                  (iii) the purchase of fractional interests in shares of any
         series of the Company's Common Stock pursuant to the conversion or
         exchange provisions of such Common Stock or the security being
         converted or exchanged;

                  (iv) dividends or distributions in any series of the Company's
         Common Stock (or rights to acquire Common Stock) or repurchases,
         acquisitions or redemptions of Common Stock in connection with the
         issuance or exchange of any series of Common Stock (or securities
         convertible into or exchangeable for shares of the Company's Common
         Stock); or

                  (v) redemptions, exchanges or repurchases of any rights
         outstanding under a shareholder rights plan or the declaration or
         payment thereunder of a dividend or distribution of or with respect to
         rights in the future.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights and
obligations of the Holders to receive and the obligation of the Company to pay
Contract Adjustment Payments, if any, or any Deferred Contract Adjustment
Payments, and the rights of the Holders to purchase Common Stock, shall
immediately and automatically terminate, without the necessity of any notice or
action by any Holder, the Agent or the Company, if, on or prior to the Stock
Purchase Date, a Termination Event shall have occurred. Upon the occurrence of a
Termination Event, the Company shall promptly but in no event later than two
Business Days thereafter give written notice to the Agent, the Collateral Agent
and to the Holders, at their addresses as they appear in the Equity Security
Units Register. Upon and after the occurrence of a Termination Event, the
Collateral Agent shall release the

                                      A-10
<PAGE>

Pledged Notes, Pledged Treasury Consideration or Pledged Applicable Ownership
Interests in the Treasury Portfolio, as the case may be, from the Pledge in
accordance with the provisions of the Pledge Agreement.

         Upon registration of transfer of this Equity Security Units
Certificate, the transferee shall be bound (without the necessity of any other
action on the part of such transferee, except as may be required by the Agent
pursuant to the Purchase Contract Agreement), by the terms of the Purchase
Contract Agreement and the Purchase Contracts evidenced hereby and the
transferor shall be released from the obligations under the Purchase Contracts
evidenced by this Equity Security Units Certificate. The Company covenants and
agrees, and the Holder, by its acceptance hereof, likewise covenants and agrees,
to be bound by the provisions of this paragraph.

         The Holder of this Equity Security Units Certificate, by its acceptance
hereof, authorizes the Agent to enter into and perform the related Purchase
Contracts forming part of the Equity Security Units evidenced hereby on its
behalf as its attorney-in-fact, expressly withholds any consent to the
assumption (i.e., affirmance) of the Purchase Contracts by the Company or its
trustee in the event that the Company becomes the subject of a case under the
Bankruptcy Code, agrees to be bound by the terms and provisions of the Purchase
Contracts, covenants and agrees to perform such Holder's obligations under such
Purchase Contracts, consents to the provisions of the Purchase Contract
Agreement, irrevocably authorizes the Agent to enter into and perform the Pledge
Agreement on such Holder's behalf as attorney-in-fact, and consents to and
agrees to be bound by the Pledge of the Notes, the Treasury Consideration or
Applicable Ownership Interests in the Treasury Portfolio, as the case may be,
underlying this Equity Security Units Certificate pursuant to the Pledge
Agreement. The Holder further covenants and agrees, that, to the extent and in
the manner provided in the Purchase Contract Agreement and the Pledge Agreement,
but subject to the terms thereof, payments in respect of the Pledged Notes,
Pledged Treasury Consideration or Pledged Applicable Ownership Interests in the
Treasury Portfolio, as the case may be, to be paid upon settlement of such
Holder's obligations to purchase Common Stock under the Purchase Contract, shall
be paid on the Stock Purchase Date by the Collateral Agent to the Company in
satisfaction of such Holder's obligations under such Purchase Contract and such
Holder shall acquire no right, title or interest in such payments.

         The Company and each Holder of an Equity Security Unit, and each
Beneficial Owner thereof, by its acceptance thereof or of its interest therein,
further agrees to treat:

                  (i) the purchase of the Equity Security Unit as the purchase
         of the Note and the Purchase Contract constituting the Equity Security
         Unit and to allocate the purchase price of the Equity Security Unit
         between the Note and the Purchase Contract as $50 and $0, respectively;
         and

                  (ii) the Holder as the owner of the applicable interest in the
         Collateral Account, including the Notes, Treasury Consideration or
         Applicable Ownership Interests in the Treasury Portfolio, as the case
         may be.

         Each Holder of an Equity Security Unit represents and warrants on each
day from and including the date of its acquisition of the Equity Security Unit
through and including the date of the satisfaction of the obligations under the
Purchase Contract and/or the disposition of such

                                      A-11
<PAGE>

Equity Security Unit that either (i) no portion of the assets used by such
Holder to acquire the Equity Security Unit constitutes the assets of any Plan or
(ii) the acquisition, holding and disposition of the Equity Security Unit by
such Holder does not and will not constitute a non-exempt prohibited transaction
under ERISA or Section 4975 of the Code or a violation of any Similar Laws.

         Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Outstanding Units, with the Equity Security Units and Stripped Units voting
together as one class.

         The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.

         Each Holder of an Equity Security Unit, by its acceptance thereof, the
Company and the Agent each submit to the jurisdiction of the courts of the State
of New York and the courts of the United States of America, in each case located
in the Borough of Manhattan, City of New York and State of New York over any
suit, action or proceeding with respect to this Agreement or the transactions
contemplated hereby. Each Holder of an Equity Security Unit, by its acceptance
thereof, the Company and the Agent each waive any objection that any of them may
have to the venue of any suit, action or proceeding with respect to this
Agreement or the transactions contemplated hereby in the courts of the State of
New York or the courts of the United States of America, in each case located in
the Borough of Manhattan, City of New York and State of New York, or that such
suit, action or proceeding brought in the courts of the State of New York or the
courts of the United States of America, in each case located in the Borough of
Manhattan, City of New York and State of New York, was brought in an
inconvenient court and agrees not to plead or claim the same.

         Each Holder of an Equity Security Unit, by its acceptance thereof, the
Company and the Agent each acknowledge and agree that any controversy which may
arise under this Agreement is likely to involve complicated and difficult
issues, and therefore irrevocably and unconditionally waive any right it may
have to a trial by jury in respect of any litigation directly or indirectly
arising out of relating to this Agreement or the transactions contemplated
hereby.

         The Company, the Agent and any agent of the Company or the Agent may
treat the Person in whose name this Equity Security Units Certificate is
registered as the owner of the Equity Security Units evidenced hereby for the
purpose of receiving quarterly payments on the Notes, the Treasury Consideration
or the Applicable Ownership Interests in the Treasury Portfolio, as the case may
be, receiving payments of Contract Adjustment Payments, if any, and any Deferred
Contract Adjustment Payments, performance of the Purchase Contracts and for all
other purposes whatsoever (subject to the Record Date provisions hereof),
whether or not any payments in respect thereof be overdue and notwithstanding
any notice to the contrary, and neither the Company, the Agent, nor any such
agent shall be affected by notice to the contrary.

         The Purchase Contracts shall not, prior to the settlement thereof,
entitle the Holder to any of the rights of a holder of shares of Common Stock.

         A copy of the Purchase Contract Agreement is available for inspection
by any Holder at the Corporate Trust Office.

         This Stripped Units Certificate certifies that [For inclusion in Global

Trust Company] is the registered Holder of the number of Stripped Units set
forth above [For inclusion in Global Certificates only - or such other number of

Agreement, and (ii) the rights and obligations of the Holder under one Purchase
Contract with El Paso Corporation, a Delaware corporation (the "Company"). All

         Pursuant to the Pledge Agreement, the Treasury Security constituting

         Each Purchase Contract evidenced hereby obligates the Holder of this
Stripped Units Certificate to purchase, and the Company to sell, on the Stock
Purchase Date, at a price equal to $50 (the "Stated Amount"), a number of shares
of common stock, par value $3.00 per share ("Common Stock"), of the Company,
equal to the Settlement Rate, unless on or prior to the Stock Purchase Date
there shall have occurred a Termination Event or an Early Settlement or Merger
Early Settlement with respect to the Stripped Units of which such Purchase
Contract is a part, all as provided in the Purchase Contract Agreement and more
fully described on the reverse hereof. The Purchase Price (as defined herein)
for the shares of Common Stock purchased pursuant to each Purchase Contract
evidenced hereby, if not paid earlier, shall be paid on the Stock Purchase Date
by application of payments received in respect of the Pledged Treasury
Securities pledged to secure the obligations under such Purchase Contract in
accordance with the terms of the Pledge Agreement.

         The Company shall pay on each Payment Date in respect of each Purchase
Contract forming part of a Stripped Units evidenced hereby an amount (the
"Contract Adjustment Payments") equal to 2.86% per year of the Stated Amount,
computed on the basis of a 360-day year of twelve 30-day months, subject to
deferral at the option of the Company as provided in the Purchase Contract
Agreement and more fully described on the reverse hereof. Such Contract
Adjustment Payments shall be payable to the Person in whose name this Stripped
Units Certificate (or a Predecessor Stripped Units Certificate) is registered at
the close of business on the Record Date for such Payment Date.

         Contract Adjustment Payments, if any, will be payable at the Office of
the Agent in the City of New York or, at the option of the Company, by check
mailed to the address of the Person entitled thereto at such address as it
appears on the Stripped Units Register or by wire transfer to the account
designated by such Person in writing at least five Business Days prior to the
applicable Payment Date.

the Agent by manual signature, this Stripped Units Certificate shall not be
entitled to any benefit under the Pledge Agreement or the Purchase Contract
Agreement or be valid or obligatory for any purpose.

                     (Reverse of Stripped Units Certificate)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of June 26, 2002 (as may be amended or supplemented
from time to time, the "Purchase Contract Agreement"), between the Company and
JPMorgan Chase Bank, as Purchase Contract Agent (including its successors
thereunder, herein called the "Agent"), to which Purchase Contract Agreement and
supplemental agreements thereto reference is hereby made for a description of
the respective rights, limitations of rights, obligations, duties and immunities
thereunder of the Agent, the Company and the Holders and of the terms upon which
the Stripped Units Certificates are executed and delivered.

         Each Purchase Contract evidenced hereby obligates the Holder of this
Stripped Units Certificate to purchase, and the Company to sell, on the Stock
Purchase Date at a price equal to $50 (the "Purchase Price"), a number of shares
of Common Stock of the Company equal to the Settlement Rate, unless, on or prior
to the Stock Purchase Date, there shall have occurred a Termination Event with
respect to the Stripped Units of which such Purchase Contract is a part. The
"Settlement Rate" is equal to:

                  (a) if the Applicable Market Value (as defined below) is
         greater than or equal to $23.94 (the "Threshold Appreciation Price"),
         2.0886 shares of Common Stock per Purchase Contract;

                  (b) if the Applicable Market Value is less than the Threshold
         Appreciation Price but is greater than $19.95 (the "Reference Price"),
         the number of shares of Common Stock per Purchase Contract equal to the
         Stated Amount of the related Stripped Units divided by the Applicable
         Market Value; and

                  (c) if the Applicable Market Value is less than or equal the
         Reference Price, 2.5063 shares of Common Stock per Purchase Contract,

in each case subject to adjustment as provided in the Purchase Contract
Agreement (and in each case rounded upward or downward to the nearest 1/10,000th
of a share).

         No fractional shares of Common Stock will be issued upon settlement of
Purchase Contracts, as provided in the Purchase Contract Agreement.

         The "Applicable Market Value" means the average of the Closing Price
per share of Common Stock on each of the 20 consecutive Trading Days ending on
the third Trading Day immediately preceding the Stock Purchase Date; provided,
that, in the case of a Merger Early Settlement, the 20 consecutive Trading Days
shall end on the date of completion of the Cash Merger.

         The "Closing Price" of the Common Stock on any date of determination
means the closing sale price (or, if no closing price is reported, the last
reported sale price) of the Common Stock on the New York Stock Exchange (the
"NYSE") on such date or, if the Common Stock is not listed for trading on the
NYSE on any such date, as reported in the composite transactions for the
principal United States securities exchange on which the Common Stock is so
listed, or if the Common Stock is not so listed on a United States national or
regional securities exchange, as

                                      B-5
<PAGE>

reported by the NASDAQ Stock Market, or, if the Common Stock is not so reported,
the last quoted bid price for the Common Stock in the over-the-counter market as
reported by the National Quotation Bureau or similar organization, or, if such
bid price is not available, the market value of the Common Stock on such date as
determined by a nationally recognized independent investment banking firm
retained for this purpose by the Company.

         A "Trading Day" means a day on which the Common Stock (A) is not
suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of the Common Stock.

         Each Purchase Contract evidenced hereby may be settled prior to the
Stock Purchase Date through Early Settlement or Merger Early Settlement. Each
Purchase Contract evidenced hereby which is settled either through Early
Settlement or Merger Early Settlement shall obligate the Holder of the related
Stripped Unit to purchase at the Purchase Price, and the Company to sell, a
number of newly issued shares of Common Stock equal to the Early Settlement Rate
(in the case of an Early Settlement) or the applicable Settlement Rate (in the
case of a Merger Early Settlement).

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Stripped Units Certificate shall pay the Purchase Price for the
shares of Common Stock purchased pursuant to each Purchase Contract evidenced
hereby:

                  (i) by effecting an Early Settlement, Merger Early Settlement
         or Cash Settlement; or

                  (ii) by application of payments received in respect of the
         Pledged Treasury Securities underlying the Stripped Units represented
         by this Stripped Units Certificate.

         The Company shall not be obligated to issue any shares of Common Stock
in respect of a Purchase Contract or deliver any certificates or book-entry
interest therefor to the Holder unless it shall have received payment in full of
the aggregate Purchase Price for the shares of Common Stock to be purchased
thereunder in the manner herein set forth.

         The Stripped Units Certificates are issuable only in registered form
and only in denominations of a single Stripped Units and any integral multiple
thereof. The transfer of any Stripped Units Certificate will be registered and
Stripped Units Certificates may be exchanged as provided in the Purchase
Contract Agreement. The Stripped Units Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents
permitted by the Purchase Contract Agreement. No service charge shall be
required for any such registration of transfer or exchange, but the Company and
the Agent may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith.

         A Holder of Stripped Units may substitute for the Pledged Treasury
Securities securing its obligations under the related Purchase Contracts Notes
in accordance with the terms of, and subject to the limitations set forth in,
the Purchase Contract Agreement and the Pledge Agreement. Holders may recreate
Equity Security Units only in integral multiples of 20 Stripped Units. From and
after such substitution, the Units for which such Pledged Notes secure the
Holder's obligation

                                      B-6
<PAGE>

under the Purchase Contract shall be referred to as "Equity Security Units." A
Holder that elects to substitute Notes for Pledged Treasury Securities, thereby
recreating Equity Security Units, shall be responsible for any fees or expenses
payable in connection therewith. Except as provided in the Purchase Contract
Agreement, for so long as the Purchase Contract underlying a Stripped Unit
remains in effect, the rights and obligations of the Holder of such Stripped
Units in respect of the Pledged Treasury Security and the Purchase Contract
constituting such Stripped Units may be transferred and exchanged only as a
Stripped Unit.

         Subject to the next succeeding paragraph, the Company shall pay on each
Payment Date, the Contract Adjustment Payments, if any, payable in respect of
each Purchase Contract to the Person in whose name the Stripped Units
Certificate evidencing such Purchase Contract is registered at the close of
business on the Record Date for such Payment Date. Contract Adjustment Payments,
if any, will be payable at the Office of the Agent in the City of New York or,
at the option of the Company, by check mailed to the address of the Person
entitled thereto at such address as it appears on the Stripped Units Register or
by wire transfer to the account designated by such Person in writing at least
five Business Days prior to the applicable Payment Date.

         The Company shall have the right, at any time prior to the Stock
Purchase Date, to defer the payment of any or all of the Contract Adjustment
Payments otherwise payable on any Payment Date, but only if the Company shall
give the Holders and the Agent written notice of its election to defer Contract
Adjustment Payments as provided in the Purchase Contract Agreement. Any Contract
Adjustment Payments so deferred shall, to the extent permitted by law, bear
additional Contract Adjustment Payments thereon at the rate of 6.14% per year
(computed on the basis of a 360-day year of twelve 30-day months), compounding
on each succeeding Payment Date, until paid in full (such deferred installments
of Contract Adjustment Payments, if any, together with the additional Contract
Adjustment Payments, if any, accrued thereon, are referred to herein as the
"Deferred Contract Adjustment Payments"). Deferred Contract Adjustment Payments,
if any, shall be due on the next succeeding Payment Date except to the extent
that payment is deferred pursuant to the Purchase Contract Agreement. No
Contract Adjustment Payments may be deferred to a date that is after the Stock
Purchase Date and no such deferral period may end other than on a Payment Date.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments on the Purchase Contracts until a Payment Date prior to the
Stock Purchase Date, then all Deferred Contract Adjustment Payments, if any,
shall be payable to the registered Holders as of the close of business on the
Record Date immediately preceding such Payment Date.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments on the Purchase Contracts until the Stock Purchase Date, the
Company may elect to pay each Holder on the Stock Purchase Date in respect of
the Deferred Contract Adjustment Payments, in lieu of a cash payment, a number
of shares of Common Stock (in addition to the number of shares of Common Stock
equal to the Settlement Rate) equal to (A) the aggregate amount of Deferred
Contract Adjustment Payments payable to such Holder (net of any required tax
withholding on such Deferred Contract Adjustment Payments, which shall be
remitted to the appropriate taxing jurisdiction) divided by (B) the Applicable
Market Value.

                                      B-7
<PAGE>

         In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, then, until the Deferred Contract Adjustment
Payments have been paid, the Company shall not declare or pay dividends on, make
distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any of its Common Stock other than:

                  (i) purchases, redemptions or acquisitions of shares of Common
         Stock in connection with any employment contract, benefit plan or other
         similar arrangement with or for the benefit of employees, officers or
         directors or a stock purchase or dividend reinvestment plan, or the
         satisfaction by the Company of its obligations pursuant to any contract
         or security outstanding on the date the Company exercises its rights to
         defer the Contract Adjustment Payments;

                  (ii) as a result of a reclassification of the Company's
         Capital Stock or the exchange or conversion of one class or series of
         the Company's Capital Stock for another class or series of the
         Company's Capital Stock;

                  (iii) the purchase of fractional interests in shares of any
         series of the Company's Common Stock pursuant to the conversion or
         exchange provisions of such Common Stock or the security being
         converted or exchanged;

                  (iv) dividends or distributions in any series of the Company's
         Common Stock (or rights to acquire Common Stock) or repurchases,
         acquisitions or redemptions of Common Stock in connection with the
         issuance or exchange of any series of Common Stock (or securities
         convertible into or exchangeable for shares of the Company's Common
         Stock; or

                  (v) redemptions, exchanges or repurchases of any rights
         outstanding under a shareholder rights plan or the declaration or
         payment thereunder of a dividend or distribution of or with respect to
         rights in the future.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights and
obligations of Holders to receive and the obligation of the Company to pay
Contract Adjustment Payments, if any, or any Deferred Contract Adjustment
Payments, and the rights and obligations of Holders to purchase Common Stock,
shall immediately and automatically terminate, without the necessity of any
notice or action by any Holder, the Agent or the Company, if, on or prior to the
Stock Purchase Date, a Termination Event shall have occurred. Upon the
occurrence of a Termination Event, the Company shall promptly but in no event
later than two Business Days thereafter give written notice to the Agent, the
Collateral Agent and to the Holders, at their addresses as they appear in the
Stripped Units Register. Upon and after the occurrence of a Termination Event,
the Collateral Agent shall release the Pledged Treasury Securities from the
Pledge in accordance with the provisions of the Pledge Agreement.

         Upon registration of transfer of this Stripped Units Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to the
Purchase Contract Agreement), by the terms of the Purchase Contract Agreement
and the Purchase Contracts evidenced hereby and the transferor shall be

                                      B-8
<PAGE>
released from the obligations under the Purchase Contracts evidenced by this
Stripped Units Certificate. The Company covenants and agrees, and the Holder, by
its acceptance hereof, likewise covenants and agrees, to be bound by the
provisions of this paragraph.

         The Holder of this Stripped Units Certificate, by its acceptance
hereof, authorizes the Agent to enter into and perform the related Purchase
Contracts forming part of the Stripped Units evidenced hereby on its behalf as
its attorney-in-fact, expressly withholds any consent to the assumption (i.e.,
affirmance) of the Purchase Contracts by the Company or its trustee in the event
that the Company becomes the subject of a case under the Bankruptcy Code, agrees
to be bound by the terms and provisions of the Purchase Contracts, covenants and
agrees to perform such Holder's obligations under such Purchase Contracts,
consents to the provisions of the Purchase Contract Agreement, irrevocably
authorizes the Agent to enter into and perform the Pledge Agreement on such
Holder's behalf as attorney-in-fact, and consents to and agrees to be bound by
the Pledge of the Treasury Securities underlying this Stripped Units Certificate
pursuant to the Pledge Agreement. The Holder further covenants and agrees, that,
to the extent and in the manner provided in the Purchase Contract Agreement and
the Pledge Agreement, but subject to the terms thereof, payments in respect of
the Pledged Treasury Securities, to be paid upon settlement of such Holder's
obligations to purchase Common Stock under the Purchase Contract, shall be paid
on the Stock Purchase Date by the Collateral Agent to the Company in
satisfaction of such Holder's obligations under such Purchase Contract and such
Holder shall acquire no right, title or interest in such payments.

         The Company and each Holder of any Stripped Units, and each Beneficial
Owner thereof, by its acceptance thereof or of its interest therein, further
agrees to treat:

                  (i) the ownership of Stripped Units as the ownership of the
         Purchase Contract and the Treasury Securities; and

                  (ii) the Holder as the owner of the applicable interest in the
         Collateral Account, including the Treasury Securities.

         Each Holder of a Stripped Unit represents and warrants on each day from
and including the date of its acquisition of the Stripped Unit through and
including the date of the satisfaction of the obligation under the Purchase
Contract and/or the disposition of such Stripped Unit that either (i) no portion
of the assets used by such Holder to acquire the Stripped Unit constitute the
assets of any Plan or (ii) the acquisition, holding and disposition of the
Stripped Unit by such Holder does not and will not constitute a non-exempt
prohibited transaction under ERISA or Section 4975 of the Code or a violation of
any Similar Laws.

         Subject to certain exceptions, the provisions of the Purchase Contract
Agreement may be amended with the consent of the Holders of a majority of the
Outstanding Units, with the Equity Security Units and Stripped Units voting
together as one class.

         The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York.

         Each Holder of a Stripped Unit, by its acceptance thereof, the Company
and the Agent each submit to the jurisdiction of the courts of the State of New
York and the courts of the United States

                                      B-9

of America, in each case located in the Borough of Manhattan, City of New York
and State of New York over any suit, action or proceeding with respect to this
Agreement or the transactions contemplated hereby. Each Holder of a Stripped
Unit, by its acceptance thereof, the Company and the Agent each waive any
objection that any of them may have to the venue of any suit, action or
proceeding with respect to this Agreement or the transactions contemplated
hereby in the courts of the State of New York or the courts of the United States
of America, in each case located in the Borough of Manhattan, City of New York
and State of New York, or that such suit, action or proceeding brought in the
courts of the State of New York or the courts of the United States of America,
in each case located in the Borough of Manhattan, City of New York and State of
New York, was brought in an inconvenient court and agrees not to plead or claim
the same.

         Each Holder of a Stripped Unit, by its acceptance thereof, the Company
and the Agent each acknowledge and agree that any controversy which may arise
under this Agreement is likely to involve complicated and difficult issues, and
therefore irrevocably and unconditionally waive any right it may have to a trial
by jury in respect of any litigation directly or indirectly arising out of
relating to this Agreement or the transactions contemplated hereby.

         The Company, the Agent and any agent of the Company or the Agent may
treat the Person in whose name this Stripped Units Certificate is registered as
the owner of the Stripped Units evidenced hereby for the purpose of receiving
any Contract Adjustment Payments and any Deferred Contract Adjustment Payments,
performance of the Purchase Contracts and for all other purposes whatsoever
(subject to the Record Date provisions hereof), whether or not any payments in
respect thereof be overdue and notwithstanding any notice to the contrary, and
neither the Company, the Agent, nor any such agent shall be affected by notice
to the contrary.

         The Purchase Contracts shall not, prior to the settlement thereof,
entitle the Holder to any of the rights of a holder of shares of Common Stock.

         A copy of the Purchase Contract Agreement is available for inspection
by any Holder at the Corporate Trust Office.

SECTION 2.1 The Pledge.

        (a) The Holders from time to time acting through the Purchase Contract
Agent, as their attorney-in-fact, and the Purchase Contract Agent, as such
attorney-in-fact, hereby pledge and grant to the Collateral Agent, for the
benefit of the Company, as collateral security for the performance when due by

Contracts, a continuing first priority perfected security interest in, and lien
upon and right of set off against, all of the right, title and interest of the

shall indicate by book-entry that a Securities Entitlement to such Notes has

        (c) The pledge provided in this Section 2.1 is herein referred to as the
"Pledge" and the Notes (or the Notes that are delivered pursuant to Section 4.2
hereof), Treasury Consideration, Applicable Ownership Interests in the Treasury

the Purchase Contract Agent shall use its commercially reasonable best efforts
to arrange for the Securities Intermediary to obtain physical possession of a
replacement certificate evidencing any Notes remaining subject to the Pledge
hereunder registered to the Securities Intermediary or endorsed in blank within
fifteen days of the date the Securities Intermediary relinquished possession.
The Securities Intermediary shall promptly notify the Company and the Collateral
Agent of the Securities Intermediary's failure to obtain possession of any such
replacement certificate as required hereby.

through the Purchase

Contract Agent, as their attorney-in-fact, hereby authorize and direct the
Securities Intermediary (without the necessity of obtaining the further consent
of the Purchase Contract Agent or any of the Holders), and the Securities
Intermediary agrees, to comply with and follow any instructions and entitlement
orders (as defined in Section 8-102(a)(8) of the Code) that the Collateral Agent
may deliver with respect to the Collateral Account, the Collateral credited
thereto and any Security Entitlements with respect thereto. In the event the
Securities Intermediary receives from the Holders or the Purchase Contract Agent
entitlement orders which conflict with entitlement orders received from the
Collateral Agent, the Securities Intermediary shall follow the entitlement
orders received from the Collateral Agent. Instructions and entitlement orders
may, without limitation, direct the Securities Intermediary to transfer, redeem,
assign, or otherwise deliver the Notes, the Treasury Consideration, the

Securities and any Security Entitlements with respect thereto or sell, liquidate
or dispose of such assets through a broker designated by the Company, and to pay
and deliver any income, proceeds or other funds derived therefrom to the
Company. The Holders from time to time acting through the Purchase Contract
Agent hereby further authorize and direct the Collateral Agent itself, as agent

terms and provisions hereof, all without the necessity of obtaining the further
consent of the Purchase Contract Agent or any of the Holders. The Collateral
Agent shall be the agent of the Company and shall act only in accordance with
the terms hereof. Without limiting the generality of the foregoing, the
Collateral Agent shall issue entitlement orders to the Securities Intermediary
as directed in writing by the Company.

                (i) all securities or other property underlying any financial
        assets credited to the Collateral Account shall be registered in the
        name of the Securities Intermediary, or its nominee, endorsed to the
        Securities Intermediary, or its nominee, or in blank and in no case will
        any financial asset credited to the Collateral Account be registered in
        the name of the Purchase Contract Agent, the Collateral Agent as such,
        the Company or any Holder, payable to the order of, or specially
        endorsed to, the Purchase Contract Agent, the Collateral Agent as such,
        the Company or any Holder except to the extent the foregoing have been
        specially endorsed to the Securities Intermediary or in blank;

                (ii) all property delivered to the Securities Intermediary
        pursuant to this Agreement (including, without limitation, any Notes,
        Treasury Consideration, Applicable Ownership Interests in the Treasury
        Portfolio or Treasury Securities) will be promptly credited to the
        Collateral Account;

                (iii) the Collateral Account is an account to which financial
        assets are or may be credited, and the Securities Intermediary shall,
        subject to the terms of this Agreement, comply with entitlement orders
        originated by the Collateral

                                       6
<PAGE>

        Agent on behalf of the Company without further consent by the Purchase
        Contract Agent;

                (iv) the Securities Intermediary has not entered into, and until
        the termination of this Agreement will not enter into, any agreement
        with any other Person relating to the Collateral Account and/or any
        financial assets credited thereto pursuant to which it has agreed to
        comply with entitlement orders (as defined in Section 8-102(a)(8) of the
        Code) of such other Person;

                (v) the Securities Intermediary has not entered into, and until
        the termination of this Agreement will not enter into, any agreement
        with the Company, the Collateral Agent or the Purchase Contract Agent
        purporting to limit or condition the obligation of the Securities
        Intermediary to comply with entitlement orders as set forth in this
        Section 2.2;

                (vi) each item of property (whether investment property,
        financial asset, security, instrument or cash) credited to the
        Collateral Account shall be treated as a "financial asset" within the
        meaning of Section 8-102(a)(9) of the Code; and

                (vii) in the event of any conflict between this Agreement (or
        any portion thereof) and any other agreement now existing or hereafter
        entered into, the terms of this Agreement shall prevail.

        (c) The Purchase Contract Agent hereby irrevocably constitutes and
appoints the Collateral Agent and the Company, with full power of substitution,
as the Purchase Contract Agent's attorney-in-fact to take on behalf of, and in
the name, place and stead of, the Purchase Contract Agent and the Holders, any
action necessary or desirable to perfect and to keep perfected the security
interest in the Collateral referred to in Section 2.1. The grant of such
power-of-attorney shall not be deemed to require of the Collateral Agent any
specific duties or obligations not otherwise assumed by the Collateral Agent
hereunder. Notwithstanding the foregoing, in no event shall the Collateral Agent
or Securities Intermediary be responsible for the preparation or filing of any
financing or continuation statements in the appropriate jurisdictions or
responsible for maintenance or perfection of any security interest hereunder.

        (d) The Purchase Contract Agent shall file with the Internal Revenue
Service and deliver to the Holders Forms 1099 (or successor or comparable
forms), to the extent required by law, with respect to payments to the Holders.
Neither the Securities Intermediary nor the Collateral Agent shall have any tax
reporting duties hereunder.

written instruction from the Purchase Contract Agent, the Collateral Agent shall
release the Pledged Notes and shall promptly Transfer such Pledged Notes free
and clear of any lien, pledge or security interest created hereby, to the
Purchase Contract Agent. All items Transferred and/or substituted by any Holder
pursuant to this Section 4.1, Section 4.2 or any other Section of this Agreement

Units are so transferred or the Equity Security Units Certificate is so
delivered, as the case may be, or, with respect to an Equity Security Units
Certificate, such Holder provides evidence satisfactory to the Company and the
Purchase Contract Agent that such Equity Security Units Certificate has been
destroyed, lost or stolen, together with any indemnity that may be required by
the Purchase Contract Agent and the Company.

        (a) Unless a successful remarketing or a Tax Event Redemption has
occurred, at any time (i) other than during the period that commences at 5:00
p.m., New York City time, on May 5, 2005 and ends at 9:00 a.m., New York City

principal amount equal to the aggregate stated amount of such Stripped Units and
(y) delivering instructions to the Purchase Contract Agent, in its capacity as
custodian for the Depositary, to decrease the number of Stripped Units evidenced

in certificated form, such Stripped Units) to the Purchase Contract Agent,
accompanied by a notice, substantially in the form of Exhibit B hereto, to the
Purchase Contract Agent stating that such Holder has Transferred Notes to the
Collateral Agent pursuant to clause (x) above and requesting that the Purchase
Contract Agent instruct the Collateral Agent to release from the Pledge the
Pledged Treasury Securities related to such Stripped Units, whereupon the
Purchase Contract Agent shall give such instruction to the Collateral Agent in
the form provided in Exhibit A. Upon receipt of the Separate Notes from such
Holder and the instruction from the Purchase Contract Agent, the Collateral
Agent shall release the Pledged Treasury Securities and shall promptly Transfer
such Pledged Treasury Securities, free and clear of any lien, pledge or security
interest created hereby, to the Purchase Contract Agent.

        (b) Holders of Stripped Units who recreate Equity Security Units by

        (c) In the event a Holder who recreates Equity Security Units fails to
effect a book-entry transfer of the Stripped Units or fails to deliver a
Stripped Units Certificate to the Purchase Contract Agent after depositing Notes
with the Collateral Agent, the Treasury Securities constituting a part of such
Stripped Units, and any distributions on such Treasury Securities shall be held
in the name of the Purchase Contract Agent or its nominee in trust for the
benefit of such Holder, until such Stripped Units are so transferred or the
Stripped Units Certificate is so delivered, as the case may be, or, with respect
to a Stripped Units Certificate, such Holder provides evidence satisfactory to
the Company and the Purchase Contract Agent that such Stripped Units Certificate
has been destroyed, lost or stolen, together with any indemnity that may be
required by the Purchase Contract Agent and the Company.

SECTION 4.3 Termination Event.

        (a) Upon receipt by the Collateral Agent of written notice from the
Company or the Purchase Contract Agent that there has occurred a Termination
Event, the Collateral Agent shall release all Collateral from the Pledge and
shall promptly Transfer any Pledged Notes, Pledged Treasury Consideration or
Pledged Applicable Ownership Interests in the Treasury Portfolio, as the case
may be, and Pledged Treasury Securities to the Purchase Contract Agent for the
benefit of the Holders of the Equity Security Units and the Stripped Units,
respectively, free and clear of any lien, pledge or security interest or other
interest created hereby.

        (b) If such Termination Event shall result from the Company's becoming a
debtor under the Bankruptcy Code, and if the Collateral Agent shall for any
reason fail promptly to effectuate the release and Transfer of all Pledged
Notes, Pledged Treasury Consideration, Pledged Applicable Ownership Interests in
the Treasury Portfolio, or Pledged Treasury Securities, as the case may be, as
provided by this Section 4.3, the Purchase Contract Agent shall:

                (i) use its best efforts to obtain, at the expense of the
        Company, an opinion of a nationally recognized law firm reasonably
        acceptable to the Collateral Agent to the effect that, as a result of
        the Company's 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 4.3, and shall deliver such
        opinion to the Collateral Agent within ten days after the occurrence of
        such Termination Event, and if (y) the Purchase Contract Agent shall be
        unable to obtain such opinion within ten days after the occurrence of
        such Termination Event or (z) the Collateral Agent shall continue, after
        delivery of such opinion, to refuse to effectuate the release and
        Transfer of all Pledged Notes, Pledged Treasury Consideration, Pledged
        Applicable Ownership Interests in the Treasury Portfolio or Pledged
        Treasury Securities, as the case may be, as provided in this Section
        4.3, then the Purchase Contract Agent shall within fifteen days after
        the occurrence of such Termination Event commence an action or
        proceeding in the court with jurisdiction of the Company's case under
        the Bankruptcy Code seeking an order requiring the Collateral Agent to
        effectuate the release and Transfer of all Pledged Notes, Pledged
        Treasury Consideration, Pledged Applicable Ownership Interests in the
        Treasury Portfolio or Pledged Treasury Securities, as the case may be,
        as provided by this Section 4.3; or

                (ii) commence an action or proceeding like that described in
        subsection (i)(z) hereof within ten days after the occurrence of such
        Termination Event.

SECTION 4.4 Early Settlement; Merger Early Settlement; Cash Settlement.

        Upon written notice to the Collateral Agent by the Purchase Contract
Agent that one or more Holders of Equity Security Units or Stripped Units have
elected to effect

                                       12
<PAGE>

Early Settlement, Merger Early Settlement or Cash Settlement of their respective
obligations under the Purchase Contracts forming a part of such Equity Security
Units or Stripped Units in accordance with the terms of the Purchase Contract
Agreement (setting forth the number of such Purchase Contracts as to which such
Holders have elected to effect Early Settlement, Merger Early Settlement or Cash
Settlement), and that, with respect to Early Settlement and Merger Early
Settlement, the Purchase Contract Agent has received and, with respect to Cash
Settlement, the Collateral Agent has received from such Holders, and paid to the
Company, the related Early Settlement Amounts, Merger Early Settlement Amounts
or Cash Settlement Amounts, as the case may be, pursuant to the terms of the
Purchase Contract Agreement and that all conditions to such Early Settlement or
Merger Early Settlement or Cash Settlement, as the case may be, have been
satisfied, then the Collateral Agent shall release from the Pledge (a) Pledged
Notes, Pledged Treasury Consideration or Pledged Applicable Ownership Interests
in the Treasury Portfolio, as the case may be, in the case of a Holder of Equity
Security Units or (b) Pledged Treasury Securities, in the case of a Holder of
Stripped Units, relating to such Purchase Contracts as to which such Holders
have elected to effect Early Settlement, Merger Early Settlement or Cash
Settlement, and shall Transfer all such Pledged Notes, Pledged Treasury
Consideration, Pledged Applicable Ownership Interests in the Treasury Portfolio
or Pledged Treasury Securities, as the case may be, free and clear of the Pledge
created hereby, to the Purchase Contract Agent for the benefit of such Holders.

SECTION 4.5 Remarketing; Application of Proceeds; Settlement.

        (a) The Collateral Agent shall notify, not later than 10:00 a.m., New
York City time, on the third Business Day preceding the Initial Remarketing Date
or the first day of any subsequent Remarketing Period, as applicable, the
Remarketing Agent of the aggregate number of Pledged Notes to be remarketed. The
Collateral Agent shall, not later than 10:00 a.m., New York City time, on the
third Business Day immediately preceding the Initial Remarketing Date or the
first day of any subsequent Remarketing Period, as applicable, without any
instruction from Holders of Equity Security Units, Transfer the Pledged Notes to
the Remarketing Agent for remarketing. Upon the occurrence of a successful
remarketing, the Remarketing Agent will deliver the Treasury Consideration
purchased from the proceeds of the successful remarketing attributable to the
Pledged Notes to the Purchase Contract Agent, which shall thereupon deliver such
Treasury Consideration to the Collateral Agent. Upon receipt of such Treasury
Consideration from the Purchase Contract Agent, the Collateral Agent, for the
benefit of the Company, shall thereupon hold in the Collateral Account such
Treasury Consideration to secure such Equity Security Units Holders' obligations
under the Purchase Contracts and to fund the quarterly payment due to Equity
Security Units Holders on the Stock Purchase Date in an amount equal to the
quarterly interest payment on the Notes, calculated at the initial annual
interest rate. On the Stock Purchase Date, the Collateral Agent shall, at the
direction of the Company, (i) apply that portion of the payments received in
respect of the Pledged Treasury Consideration equal to the aggregate Stated
Amount of the related Equity Security Units to satisfy in full the obligations
of such Equity Security Units Holders to pay the Purchase Price under the

                                       13
<PAGE>

related Purchase Contracts and (ii) apply the remaining portion to pay the
quarterly payment due to Equity Security Units Holders on such Stock Purchase
Date in an amount equal to the quarterly interest payment on the Notes,
calculated at the initial annual interest rate.

        (b) The Remarketing Agent shall make one or more attempts to remarket
the Notes in accordance with the procedures set forth in the Purchase Contract
Agreement and the Remarketing Agreement. If by 4:00 p.m., New York City time, on
the fifth Business Day immediately preceding the Stock Purchase Date, the
Remarketing Agent has failed to remarket the Notes at approximately, but not
less than, 100.5% of the Remarketing Value, the Last Failed Remarketing shall be
deemed to have occurred. Within three Business Days following the Last Failed
Remarketing, the Pledged Notes delivered to the Remarketing Agent pursuant to
Section 4.5(a) hereof shall be returned to the Collateral Agent. In this case,
the Remarketing Agent shall advise the Collateral Agent in writing that it
cannot remarket the related Pledged Notes of such Holders of Equity Security
Units, and the Holders of Equity Security Units that have not made an Early
Settlement, Merger Early Settlement or Cash Settlement shall be deemed to have
directed the Company to sell or deliver the Pledged Notes in full satisfaction
of their obligations under the Purchase Contracts. Pursuant to the written
direction of the Company, the Collateral Agent, for the benefit of the Company,
will sell or deliver the Pledged Notes in accordance with the Company's written
direction to satisfy in full, from any such sale or delivery, such Holders'
obligations under the related Purchase Contracts to pay the Purchase Price for
the Common Stock; provided, that if upon the Last Failed Remarketing, the
Collateral Agent sells or delivers the Pledged Notes in accordance with the
written direction of the Company, any accrued and unpaid interest on such Notes
will become payable by the Company to the Purchase Contract Agent for payment to
the Holders of the Equity Security Units to which such Notes relate in
accordance with the Purchase Contract Agreement.

        (c) In the event a Holder of Stripped Units has not effected a Cash
Settlement, Early Settlement or Merger Early Settlement of the Purchase
Contracts underlying its Stripped Units, such Holder shall be deemed to have
elected to pay for the shares of Common Stock to be issued under such Purchase
Contracts from the payments received in respect of the related Pledged Treasury
Securities. Without receiving any instruction from any such Holder, the
Collateral Agent shall apply such payments to the settlement of such Purchase
Contracts on the Stock Purchase Date pursuant to the written instruction of the
Purchase Contract Agent. In the event the payments received in respect of the
related Pledged Treasury Securities are in excess of the aggregate Purchase
Price under the Purchase Contracts being settled thereby, the Collateral Agent
shall distribute such excess, when received, to the Purchase Contract Agent for
the benefit of such Holders of the Stripped Units.

        (d) At any time after the Payment Date immediately preceding the Initial
Remarketing Date and prior to 11:00 a.m., New York City time, on the fourth
Business Day immediately preceding the Initial Remarketing Date or the first day
of any subsequent Remarketing Period, as applicable, holders of Separate Notes
may elect to

                                       14
<PAGE>

have their Separate Notes remarketed by Transferring their Separate Notes and
delivering a notice of such election, substantially in the form of Exhibit C
hereto, to the Custodial Agent. On the third Business Day immediately preceding
the Initial Remarketing Date or the first day of any subsequent Remarketing
Period, as applicable, by 10:00 a.m., New York City time, the Custodial Agent
shall notify the Remarketing Agent of the number of such Separate Notes to be
remarketed. The Custodial Agent will hold such Separate Notes in an account
separate from the Collateral Account. A holder of Separate Notes electing to
have its Separate Notes remarketed will also have the right to withdraw such
election by written notice to the Custodial Agent, substantially in the form of
Exhibit D hereto, prior to 11:00 a.m., New York City time, on the fourth
Business Day immediately preceding the Initial Remarketing Date or first day of
a subsequent Remarketing Period, as applicable, upon which notice the Custodial
Agent will return such Separate Notes to such holder. On the third Business Day
immediately preceding the Initial Remarketing Date or the first day of any
subsequent Remarketing Period, as applicable, the Custodial Agent at the written
direction of the Remarketing Agent will deliver to the Remarketing Agent for
remarketing all Separate Notes delivered to the Custodial Agent pursuant to this
Section 4.5(d) and not withdrawn pursuant to the terms hereof. After deducting
as the remarketing fee an amount not exceeding 25 basis points (0.25%) of the
total proceeds of such remarketing of such Separate Notes, the Remarketing Agent
will remit to the Custodial Agent the portion of the proceeds from such
remarketing, if successful, equal to the amount calculated in respect of such
Separate Notes as set forth in Section 2.06 of the Supplemental Indenture. If,
despite using its commercially reasonable best efforts, the Remarketing Agent
advises the Custodial Agent in writing that there has been a Failed Remarketing,
the Remarketing Agent will promptly return such Separate Notes to the Custodial
Agent for redelivery to such holders of such Separate Notes. The Custodial Agent
shall be entitled to rely without further inquiry on any written instructions
received from a holder of Separate Notes and shall have no liability with
respect thereto. For purposes of this Section 4.5(d), a "holder" of a Separate
Note shall mean the Person in whose name such Separate Note is registered on the
books of the registrar for the Notes.

SECTION 5.1 Exercise by Purchase Contract Agent.

        Subject to the terms of the Purchase Contract Agreement, the Purchase
Contract Agent may exercise, or refrain from exercising, any and all voting and
other consensual rights pertaining to the Pledged Notes 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 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 Notes, including
notice of any meeting at which holders of Notes are entitled to vote or

                                       15
<PAGE>

solicitation of consents, waivers or proxies of holders of Notes, 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 Notes (in form and substance satisfactory to the
Collateral Agent) as are prepared by the Purchase Contract Agent with respect to
the Pledged Notes.

                                   ARTICLE VI

                    RIGHTS AND REMEDIES; TAX EVENT REDEMPTION

SECTION 6.1 Rights and Remedies of the Collateral Agent.

        (a) In addition to the rights and remedies available at law or in
equity, after an event of default (as specified in Section 6.1(b)) hereunder,
the Collateral Agent on behalf of the Company shall have all of the rights and
remedies with respect to the Collateral of a secured party under the Uniform
Commercial Code (or any successor thereto) as in effect in the State of New York
from time to time (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. Wherever reference is made in this Agreement
to any section of the Code, such reference shall be deemed to include a
reference to any provision of the Code, which is a successor to, or amendment
of, such section. Without limiting the generality of the foregoing, such
remedies may include, to the extent permitted by applicable law, (i) retention
of the Pledged Notes or other Collateral in full satisfaction of the Holders'
obligations under the Purchase Contracts or (ii) sale of the Pledged Notes or
other Collateral in one or more public or private sales, in each case at the
written direction of the Company.

        (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 any Pledged Treasury
Consideration, Pledged Applicable Ownership Interests in the Treasury Portfolio
or Pledged Treasury Securities as provided in Article III hereof in satisfaction
of the obligations of the Holder of the Equity Security Units or Stripped Units
of which such Pledged Treasury Consideration, Pledged Applicable Ownership
Interests in the Treasury Portfolio or 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 on behalf of the Company shall have and may exercise, with
reference to such Pledged Treasury Consideration, Pledged Applicable Ownership
Interests in the Treasury Portfolio or Pledged Treasury Securities, 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.

                                       16
<PAGE>

        (c) Without limiting any rights or powers otherwise granted by this
Agreement to the Collateral Agent, the Collateral Agent on behalf of the Company
is hereby irrevocably authorized to receive and collect all payments of (i) the
principal amount of, or interest on, the Pledged Notes, or (ii) the principal
amount of, or interest (if any) on, the Pledged Treasury Consideration, Pledged
Applicable Ownership Interests in the Treasury Portfolio or Pledged Treasury
Securities, subject, in each case, to the provisions of Article III, and as
otherwise granted herein.

        (d) The Purchase Contract Agent, individually and as attorney-in-fact
for each Holder of Equity Security Units and Stripped Units, agrees that, from
time to time, upon the written request of the Company or the Collateral Agent
(acting upon the written request of the Company), the Purchase Contract Agent or
such Holder shall execute and deliver such further documents and do such other
acts and things as the Company or the Collateral Agent (acting upon the written
request of the Company) 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. Notwithstanding the foregoing, in no event shall the
Purchase Contract Agent be responsible for the preparation or filing of
financing or continuation statements in the appropriate jurisdictions or
responsible for maintenance or perfection of any security interest hereunder.
The Purchase Contract Agent shall have no liability to any Holder for executing
any documents or taking any such acts requested by the Company or the Collateral
Agent (acting upon the written request of the Company) hereunder, except for
liability for its own negligent act, its own negligent failure to act, its bad
faith or its own willful misconduct.

SECTION 6.2 Substitutions.

        Whenever a Holder has the right to substitute Treasury Securities or
Notes for Collateral held by the Collateral Agent, such substitution shall not
constitute a novation of the security interest created hereby.

SECTION 6.3 Tax Event Redemption.

        Upon the occurrence of a Tax Event Redemption prior to the earlier of
the date of a successful remarketing of the Pledged Notes or the Stock Purchase
Date, the aggregate Redemption Price payable on the Tax Event Redemption Date
with respect to such Pledged Notes shall be delivered to the Collateral Agent by
the Trustee at or prior to 12:00 p.m., New York City time, by wire transfer in
immediately available funds at such place and at such account as may be
designated by the Collateral Agent in exchange for the Pledged Notes. In the
event the Collateral Agent receives such Redemption Price, the Collateral Agent
will, at the written direction of the Company, apply an amount, out of such
Redemption Price, equal to the aggregate Redemption Amount with respect to the
Pledged Notes to purchase from the Quotation Agent the Treasury Portfolio and
promptly remit the remaining portion of such Redemption Price to the Purchase
Contract Agent for payment to the Holders of Equity Security Units. The
Collateral Agent shall Transfer the Treasury Portfolio to the Collateral Account
to secure the obligation of all Holders of Equity Security Units to purchase
Common Stock of the Company under the Purchase

                                       17
<PAGE>

Contracts constituting a part of such Equity Security Units, in substitution for
the Pledged Notes. Thereafter the Collateral Agent shall have such security
interests, rights and obligations with respect to the Treasury Portfolio as it
had in respect of the Pledged Notes as provided in Articles II, III, IV, V and
VI, and any reference herein to the Notes shall be deemed to be a reference to
such Treasury Portfolio, and any reference herein to interest on the Notes shall
be deemed to be a reference to distributions on such Treasury Portfolio.

SECTION 7.1 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 and
the Company, 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;

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 Collateral Agent, free and clear of any
security interest, lien, encumbrance, call, liability to pay money or other
restriction other than the security interest and lien granted under Section 2.1
hereof;

        (c) upon the Transfer of the Collateral 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 Intermediary or other entity not within the control of
the Holder involved in the Transfer of the Collateral, including the Collateral
Agent, 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 2.2 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 2.1 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 7.2 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 and the Company 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 sale or other disposition of the Equity
Security Units and Stripped Units.

        (a) The Collateral Agent, the Custodial Agent and the Securities
Intermediary shall act as agent for the Company hereunder with such powers as
are specifically vested in the Collateral Agent, the Custodial Agent and the
Securities Intermediary by the terms of this Agreement, together with such other
powers as are reasonably incidental thereto, and shall have no duties, fiduciary
or otherwise, to any other Person. Each of the Collateral Agent, the Custodial
Agent and the Securities Intermediary:

                (i) shall have no duties or responsibilities except those
        expressly set forth in this Agreement and no implied covenants or
        obligations shall be inferred from this Agreement against any of them,
        nor shall any of them be bound by the provisions of any agreement by any
        party hereto beyond the specific terms hereof;

                (ii) 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 Equity
        Security Units or Stripped Units 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 Custodial Agent or the Securities Intermediary, as the case
        may be), the Equity Security Units or Stripped Units 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, the Custodial Agent or the Securities
        Intermediary,

                                       19
<PAGE>

        as the case may be) to perform any of its obligations hereunder or
        thereunder or for the attachment, perfection, priority or, except as
        expressly required hereby, existence, validity, perfection or
        maintenance of any lien or security interest created hereunder;

                (iii) shall not be required to initiate or conduct any
        litigation or collection proceedings hereunder (except in the case of
        the Collateral Agent, pursuant to written directions furnished under
        Section 8.2 hereof, subject to Section 8.6 hereof);

                (iv) 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 gross negligence or willful misconduct;
        and

                (v) shall not be required to advise any party as to selling or
        retaining, or taking or refraining from taking any action with respect
        to, the Equity Security Units or Stripped Units 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.

        (b) No provision of this Agreement shall require the Collateral Agent,
the Custodial Agent or the Securities Intermediary 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, the Custodial
Agent or the Securities Intermediary be liable for any amount in excess of the
value of the Collateral or for any special, indirect, individual or
consequential damages or lost profits or loss of business, arising in connection
with this Agreement even if the Collateral Agent, the Custodial Agent or the
Securities Intermediary has been advised of the likelihood of such loss or
damage being incurred and regardless of the form of action. Notwithstanding the
foregoing, the Collateral Agent, the Custodial Agent, the Purchase Contract
Agent and the Securities Intermediary, each in its individual capacity, hereby
waive any right of setoff, banker's lien, liens or perfection rights as
securities intermediary or any counterclaim with respect to any of the
Collateral.

        (c) The Collateral Agent, Custodial Agent and Securities Intermediary
shall have no liability whatsoever for the action or inaction of any Clearing
Agency or any book-entry system thereof. In no event shall any Clearing Agency
or any book-entry system thereof be deemed an agent or subcustodian of the
Collateral Agent, Custodial Agent and Securities Intermediary. The Collateral
Agent, Custodial Agent and Securities Intermediary shall not be responsible or
liable for any failure or delay in the performance of its obligations under this
Agreement arising out of or caused, directly or indirectly, by circumstances
beyond its reasonable control, including, without limitation, acts of God;
earthquakes; fires; floods; war (whether declared or undeclared); terrorism;
civil or

                                       20

military disturbances; sabotage; epidemics; riots; interruptions, loss or
malfunctions of utilities, computer (hardware or software) or communications
service; accidents; labor disputes; acts of civil or military authority;
governmental actions; or inability to obtain labor, material, equipment or
transportation.

        (d) Notwithstanding anything to the contrary contained in this Article
VIII, the Securities Intermediary shall have the duties and responsibilities of
a securities intermediary under Article 8 of the Code, including without
limitation, Sections 8-504, 8-505, 8-506, 8-507, 8-508 and 8-509.

SECTION 8.2 Instructions of the Company.

        The Company shall have the right, by one or more instruments in writing
executed and delivered to the Collateral Agent, the Custodial Agent or the
Securities Intermediary, as the case may be, 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, the Custodial Agent or the Securities Intermediary, as the
case may be, 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, the Custodial Agent and the Securities Intermediary shall each
receive indemnity reasonably satisfactory to it as provided herein. Nothing
contained in this Section 8.2 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 8.3 Reliance.

        Each of the Collateral Agent, the Custodial Agent and the Securities
Intermediary shall be entitled conclusively to rely upon any certification,
order, judgment, opinion, notice or other communication (including, without
limitation, any thereof by telephone or facsimile) reasonably 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, the Custodial Agent or the
Securities Intermediary, as the case may be. As to any matters not expressly
provided for by this Agreement, the Collateral Agent, the Custodial 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 8.4 Rights in Other Capacities.

        The Collateral Agent, the Custodial Agent and the Securities
Intermediary and their affiliates may (without having to account therefor to the
Company) accept deposits from, lend money to, make investments in and generally
engage in any kind of banking, trust or other business with the Purchase
Contract Agent, any Holder of Equity Security

                                       21
<PAGE>

Units or Stripped Units and any holder of Separate Notes (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 and the Securities
Intermediary and their affiliates may accept fees and other consideration from
the Purchase Contract Agent, any Holder of Equity Security Units or Stripped
Units or any holder of Separate Notes without having to account for the same to
the Company; provided that each of the Collateral Agent, the Custodial Agent and
the Securities Intermediary covenants and agrees with the Company that, except
as provided in this Agreement, it shall not accept, receive or permit there to
be created in favor of itself (and waives any right of set-off or banker's lien
with respect to) 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 and the Collateral shall not
be commingled with any other assets of any such Person.

SECTION 8.5 Non-Reliance on Collateral Agent.

        None of the Collateral Agent, the Custodial Agent or the Securities
Intermediary shall be required to keep itself informed as to the performance or
observance by the Purchase Contract Agent or any Holder of Equity Security Units
or Stripped Units of this Agreement, the Purchase Contract Agreement, the Equity
Security Units or Stripped Units 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 Equity Security Units or Stripped Units. The
Collateral Agent, the Custodial Agent and the Securities Intermediary shall not
have any duty or responsibility to provide the Company or the Remarketing Agent
with any credit or other information concerning the affairs, financial condition
or business of the Purchase Contract Agent, any Holder of Equity Security Units
or Stripped Units or any holder of Separate Notes (or any of their respective
subsidiaries or affiliates) that may come into the possession of the Collateral
Agent, the Custodial Agent or the Securities Intermediary or any of their
respective affiliates.

SECTION 8.6 Compensation and Indemnity.

        The Company agrees to:

        (a) pay each of the Collateral Agent, the Custodial Agent and the
Securities Intermediary from time to time such compensation as shall be agreed
in writing between the Company and the Collateral Agent, the Custodial Agent or
the Securities Intermediary, as the case may be, for all services rendered by
each of them hereunder, and

        (b) indemnify the Collateral Agent, the Custodial Agent, the Securities
Intermediary and their officers, directors and agents for, and to hold each of
them harmless from and against, any loss, liability or reasonable out-of-pocket
expense incurred without gross negligence or willful misconduct 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

                                       22
<PAGE>

reasonable fees and expenses of counsel) incurred enforcing the Company's
indemnification obligation hereunder or defending itself against any claim or
liability in connection with the exercise or performance of such powers and
duties or collecting such amounts. The Collateral Agent, the Custodial Agent and
the Securities Intermediary shall each promptly notify the Company of any
third-party claim which may give rise to the indemnity hereunder and give the
Company the opportunity to participate in the defense of such claim with counsel
reasonably satisfactory to the indemnified party (provided, however, that if
there shall exist a conflict or potential conflict of interest between the
Company on the one hand and the Collateral Agent, the Custodial Agent or the
Securities Intermediary on the other hand, in the conduct of any such defense
which makes it impracticable for a single counsel to represent the Company and
the Collateral Agent, the Custodial Agent or the Securities Intermediary, each
of the Collateral Agent, the Custodial Agent or the Securities Intermediary, as
the case may be, shall have the right to select separate counsel to participate
in the defense of such claim), and no such claim shall be settled without the
written consent of the Company, which consent shall not be unreasonably
withheld. The provisions of this Section 8.6 shall survive the resignation or
removal of the Collateral Agent, the Custodial Agent and the Securities
Intermediary or the termination of this Agreement.

SECTION 8.7 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, the Custodial 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 to such property or funds so long as such dispute or
conflict shall continue, and none of the Collateral Agent, the Custodial Agent
or the Securities Intermediary shall 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:

                (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,
        reasonably satisfactory to the Collateral Agent, the Custodial Agent or
        the Securities Intermediary, as the case may be; or

                (ii) the Collateral Agent, the Custodial Agent or the Securities
        Intermediary, as the case may be, shall have received security or an
        indemnity reasonably satisfactory to the Collateral Agent, the Custodial
        Agent or the Securities Intermediary, as the case may be, sufficient to
        save the Collateral Agent, the Custodial Agent or the Securities
        Intermediary, as the case may be, harmless from and against any and all
        loss, liability or reasonable out-of-pocket expense which the Collateral
        Agent, the Custodial Agent or the Securities

                                       23
<PAGE>

        Intermediary, as the case may be, may incur by reason of its acting
        without willful misconduct or gross negligence.

The Collateral Agent, the Custodial Agent or 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, as the case may be, 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 8.8 Resignation.

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

        (a) the Collateral Agent, 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 Equity
Security Units and Stripped Units;

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

        (c) 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 or 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 Collateral Agent, the Custodial Agent or the Securities
Intermediary pursuant to clause (c) of the immediately preceding sentence. The
Company shall promptly notify the Purchase Contract Agent of any removal of the
Collateral Agent, the Custodial Agent or the Securities Intermediary pursuant to
clause (b) of the second preceding sentence. Upon notice of 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 and shall
give the Purchase Contract Agent prompt notice thereof. If no successor
Collateral Agent, Custodial Agent or Securities Intermediary, as the case may
be, shall have been so appointed and shall have accepted such appointment within
30 days after the retiring Collateral Agent's, the Custodial Agent's or
Securities Intermediary's giving of notice of resignation or such removal, then
the retiring Collateral Agent, the Custodial Agent or Securities Intermediary,
as the case may be, may at the Company's expense petition any court of competent
jurisdiction for the appointment of a successor Collateral Agent, the Custodial
Agent or Securities Intermediary, as the case may be. Each of the Collateral
Agent, the Custodial Agent and the Securities Intermediary shall be a bank

                                       24
<PAGE>

which has an office in New York, New York with a combined capital and surplus of
at least $50,000,000 or any affiliate of a bank holding company having such
capital and surplus. Upon the acceptance of any appointment as Collateral Agent,
Custodial Agent or Securities Intermediary, as the case may be, hereunder by a
successor Collateral Agent, Custodial Agent or Securities Intermediary, as the
case may be, such successor shall thereupon succeed to and become vested with
all the 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 to transfer any money and property held by
it hereunder (including the Collateral) to such successor after the payment of
any outstanding fees, expenses and indemnities due and owing to such retiring
party. 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 Section 8.8, and Section 8.6 hereof, 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
hereunder shall be deemed for all purposes of this Agreement as the simultaneous
resignation or removal of the Custodial Agent and the Securities Intermediary
hereunder.

        Any corporation into which the Collateral Agent, the Custodial Agent or
the Securities Intermediary, in its individual capacity, may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which the Collateral Agent in
its individual capacity shall be a party, or any corporation to which
substantially all of the corporate trust business of the Collateral Agent in its
individual capacity may be transferred, shall be the Collateral Agent, the
Custodial Agent, the Securities Intermediary, as the case may be respectively,
under this Agreement without further act.

SECTION 8.9 Right to Appoint Agent or Advisor.

        The Collateral Agent shall have the right to appoint or consult with
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 (other than legal counsel) pursuant to this Section 8.9
shall be subject to prior consent of the Company, which consent shall not be
unreasonably withheld.

SECTION 8.10 Survival.

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

                                       25

SECTION 8.11 Exculpation.

        Anything contained in this Agreement to the contrary notwithstanding, in
no event shall any of the Collateral Agent, the Custodial Agent or the
Securities Intermediary or their officers, 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, the Custodial Agent or the Securities Intermediary, or any of them, and
regardless of the form of action.

                                   ARTICLE IX

the Company (when authorized by a Board Resolution), the Collateral Agent, the
Custodial 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 Custodial Agent, the Securities
Intermediary and the Purchase Contract Agent to:

        and the assumption by any such successor of the covenants of the
        Company;

        Holders, or surrender any right or power herein conferred upon the
        Company so long as such covenants or such surrender does not adversely
        affect the validity, perfection or priority of the security interests
        granted or created hereunder;

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

                (iv) cure any ambiguity, correct or supplement any provisions
        herein which may be inconsistent with any other provisions herein, or
        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 9.2 Amendment with Consent of Holders.

respect of the Equity Security Units or Stripped Units; provided, however, that
no amendment shall, without the consent of the Holder of each Equity Security
Unit and Stripped Unit affected thereby (in addition to the consent of the
holders of at least a majority of the Outstanding Units, with the Equity
Security Units and Stripped Units voting together as one class),

                (i) change the amount or type of Collateral underlying an Equity
        Security Unit or a Stripped Unit, impair the right of the Holder of any
        Equity Security Units or Stripped Units to receive distributions on the
        underlying Collateral, or otherwise adversely affect the Holder's rights
        in or to such Collateral;

                (ii) otherwise effect any action that would require the consent
        of the Holder of each Equity Security Unit and Stripped Unit affected
        thereby pursuant to the Purchase Contract Agreement if such action were
        effected by an amendment thereto; or

                (iii) reduce the percentage of Equity Security Units and
        Stripped Units the consent of whose Holders is required for any such
        amendment.

        It shall not be necessary for any Act of Holders under this Section to

Agent, the Custodial Agent, the Securities Intermediary and the Purchase

SECTION 10.1 No Waiver.

        No failure on the part of any party hereto or any of its agents to
exercise, and no course of dealing with respect to, and no delay in exercising,

SECTION 10.2 Governing Law; Submission to Jurisdiction.

        This Agreement shall be governed by, and construed in accordance with,
the laws of the State of New York. Without limiting the foregoing, the above
choice of law is expressly agreed to by the Securities Intermediary, the
Collateral Agent, the Custodial Agent and the Holders from time to time acting
