         In any case where several matters are required to be certified by, or

or more other such Persons as to other matters, and any such Person may certify

should know, that the certificate or opinion or representations with respect to

         (a)   Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Agreement to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by an agent
duly appointed in writing; and, except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments are
delivered to the Purchase Contract Agent and, where it is hereby expressly
required, to the Company. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"ACT" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Agreement and (subject to Section 7.01)
conclusive in favor of the Purchase Contract Agent and the Company, if made in
the manner provided in this Section.

         (d)   Any request, demand, authorization, direction, notice, consent,
waiver or other Act of the Holder of any Security shall bind every future
Holder of the same Security and the Holder of every Certificate evidencing such
Security 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 Purchase Contract Agent or the Company in reliance thereon,
whether or not notation of such action is made upon such Certificate.

         (e)   The Company may set any date as a record date for the purpose of
determining the Holders of Outstanding Securities 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 Securities. If any record date is set pursuant to this paragraph, the
Holders of the Outstanding Stock Purchase Units and the Outstanding Treasury
Stock Purchase Units, as the case may

                                      13
<Page>

be, on such record date, and no other Holders, shall be entitled to take the
relevant action with respect to the Stock Purchase Units or the Treasury Stock
Purchase 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 prior to or on the applicable Expiration Date by Holders
of the requisite number of Outstanding Securities 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 be 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
Securities 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 Purchase Contract Agent in writing and to
each Holder of Securities in the manner set forth in Section 1.06.

         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 Purchase Contract Agent in writing, and to each Holder of
Securities in the manner set forth in Section 1.06, prior to or on 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 1.05.  NOTICES.

notice shall be sufficiently given (unless otherwise herein expressly provided)

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,

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 Purchase Contract Agent, but such

in reliance upon such waiver.

         In case by reason of the suspension of regular mail service or by

Contract Agent shall constitute a sufficient notification for every purpose

         The form of the Purchase Contract Agent's certificate of authentication

                                 THE SECURITIES

         SECTION 3.01. AMOUNT; FORM AND DENOMINATIONS.

         The aggregate number of Securities evidenced by Certificates
authenticated, executed on behalf of the Holders and delivered hereunder is
limited to ______________ [(_____________ if the over-allotment option granted

exchange for, or in lieu of, other Certificates pursuant to Sections 3.04, 3.05,
3.10, 3.13, 3.14, 5.07 or 8.05.

         The Certificates shall be issuable only in registered form and only in
denominations of a single Stock Purchase Unit or Treasury Stock Purchase Unit
and any integral multiple thereof.

         SECTION 3.02. RIGHTS AND OBLIGATIONS EVIDENCED BY THE CERTIFICATES.

         Each Stock Purchase Units Certificate shall evidence the number of
Stock Purchase Units specified therein, with each such Stock Purchase Unit
representing (1) the ownership by the Holder thereof of a beneficial interest in
a Preferred Security, a [Subordinated] Note or the Applicable Ownership Interest
of the Treasury Portfolio, as the case may be, subject to the Pledge of such
Preferred Security, such [Subordinated] Note or the Applicable Ownership
Interest (as specified in clause (A) of the definition of such term) of the
Treasury Portfolio, as the case may be, by such Holder pursuant to the Pledge
Agreement, and (2) the rights and obligations of the Holder thereof and the
Company under one Purchase Contract. The Purchase Contract Agent, as
attorney-in-fact for, and on behalf of, the Holder of each Stock Purchase Unit
shall pledge, pursuant to the Pledge Agreement, the Preferred Security, the
[Subordinated] Note or the Applicable Ownership Interest (as specified in clause
(A) of the definition of such term) of the Treasury Portfolio, as the case may
be, forming a part of such Stock Purchase 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 Preferred Security, such [Subordinated]

                                      19

<Page>

Note or the Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of 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 shares of Common Stock.

         Upon the formation of a Treasury Stock Purchase Unit pursuant to
Section 3.13, each Treasury Stock Purchase Units Certificate shall evidence the
number of Treasury Stock Purchase Units specified therein, with each such
Treasury Stock Purchase Unit representing (1) the ownership by the Holder
thereof of a 1/40 undivided beneficial interest in a Treasury Security with a
principal amount equal to $1,000, subject to the Pledge of such Treasury
Security by such Holder pursuant to the Pledge Agreement, and (2) the rights and
obligations of the Holder thereof and the Company under one Purchase Contract.

         Prior to the purchase of shares of Common Stock under each Purchase
Contract, such Purchase Contracts shall not entitle the Holder of a Security 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 a shareholder in respect of the meetings of
shareholders or for the election of directors of the Company or for any other
matter, or any other rights whatsoever as a shareholder of the Company.

         SECTION 3.03. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

         Subject to the provisions of Sections 3.13 and 3.14 hereof, 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
Purchase Contract Agent for authentication, execution on behalf of the Holders
and delivery, together with its Issuer Order for authentication of such
Certificates, and the Purchase Contract Agent in accordance with such Issuer
Order shall authenticate, execute on behalf of the Holders and deliver such
Certificates.

         The Certificates shall be executed on behalf of the Company by its
Chairman of the Board, its President or one of its Vice Presidents. The
signature of any of these officers on the Certificates may be manual or
facsimile.

         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.

         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 signatory of the Purchase Contract Agent, as such
Holder's attorney-in-fact. Such signature by an authorized signatory of the
Purchase Contract Agent shall be conclusive evidence that the Holder of such
Certificate has entered

                                      20

<Page>

into the Purchase Contracts evidenced by such Certificate.

         Each Certificate shall be dated the date of its authentication.

         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 signatory of the Purchase Contract 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 3.04. TEMPORARY CERTIFICATES.

         Pending the preparation of definitive Certificates, the Company shall
execute and deliver to the Purchase Contract Agent, and the Purchase Contract
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
Stock Purchase Units or Treasury Stock Purchase Units, as the case may be, are
listed, or as may, consistently herewith, be determined by the officers of the
Company executing such Certificates, as evidenced by their execution of the
Certificates.

         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 Purchase Contract
Agent, and the Purchase Contract 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
Securities 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 Securities, evidenced
thereby as definitive Certificates.

         SECTION 3.05. REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

         The Purchase Contract Agent shall keep at the Corporate Trust Office a
register (the "SECURITY REGISTER") in which, subject to such reasonable
regulations as it may prescribe, the Purchase Contract Agent shall provide for
the registration of Certificates and of transfers of Certificates (the Purchase
Contract Agent, in such capacity, the "SECURITY REGISTRAR"). The Security
Registrar shall record separately the registration and transfer of the
Certificates evidencing Stock Purchase Units

                                      21

<Page>

and Treasury Stock Purchase Units.

         Upon surrender for registration of transfer of any Certificate at the
Corporate Trust Office, the Company shall execute and deliver to the Purchase
Contract Agent, and the Purchase Contract 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
any authorized denominations, like tenor, and evidencing a like number of
Stock Purchase Units or Treasury Stock Purchase Units, as the case may be.

         At the option of the Holder, Certificates may be exchanged for other
Certificates, of any authorized denominations and evidencing a like number of
Stock Purchase Units or Treasury Stock Purchase 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 Purchase Contract Agent, and the Purchase Contract
Agent shall authenticate, execute on behalf of the Holder, and deliver the
Certificates which the Holder making the exchange is entitled to receive.

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

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

         No service charge shall be made for any registration of transfer or
exchange of a Certificate, but the Company and the Purchase Contract 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 3.06 and 8.05 not involving any transfer.

         Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Purchase Contract Agent, and the Purchase Contract
Agent shall not be obligated to authenticate, execute on behalf of the Holder
and deliver any Certificate in exchange for any other Certificate presented or
surrendered for registration of transfer or for exchange on or after the
Business Day immediately preceding the earliest of any Early Settlement Date for
such Certificate, the Purchase Contract Settlement Date or 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

                                      22

<Page>

registration or transfer instructions from such Holder, the Purchase Contract
Agent shall:

               (i)  if the Purchase Contract Settlement Date or an Early
         Settlement Date with respect to such other Certificate has occurred,
         deliver the shares of Common Stock issuable in respect of the Purchase
         Contracts forming a part of the Securities evidenced by such other
         Certificate; or

              (ii)  if a Cash Settlement or an Early Settlement Date with
         respect to such other Certificate shall have occurred, or if a
         Termination Event shall have occurred prior to the Purchase Contract
         Settlement Date, transfer the Preferred Securities, the [Subordinated]
         Notes, the Treasury Securities, or the appropriate Applicable
         Ownership Interest of the Treasury Portfolio, as the case may be,
         evidenced thereby, in each case subject to the applicable conditions
         and in accordance with the applicable provisions of Section 3.15 and
         Article Five hereof.

         SECTION 3.06. BOOK-ENTRY INTERESTS.

         The Certificates, on original issuance, will be issued in the form of
one or more fully registered Global Certificates, to be delivered to the
Depositary or its custodian by, or on behalf of, the Company. The Company hereby
designates DTC as the initial Depositary. Such Global Certificates shall
initially be registered on the books and records of the Company 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 3.09. The Purchase Contract
Agent shall enter into an agreement with the Depositary if so requested by the
Company. Unless and until definitive, fully registered Certificates have been
issued to Beneficial Owners pursuant to Section 3.09:

               (i)  the provisions of this Section 3.06 shall be in full force
         and effect;

              (ii)  the Company shall be entitled to deal with the Depositary
         for all purposes of this Agreement (including making Purchase Contract
         Payments and receiving approvals, votes or consents hereunder) as the
         Holder of the Securities and the sole holder of the Global
         Certificates and shall have no obligation to the Beneficial Owners;

             (iii)  to the extent that the provisions of this Section 3.06
         conflict with any other provisions of this Agreement, the provisions
         of this Section 3.06 shall control; and

              (iv)  the rights of the Beneficial Owners shall be exercised only
         through the Depositary and shall be limited to those established by law
         and agreements between such Beneficial Owners and the Depositary or the
         Depositary Participants.

                                      23

<Page>

         SECTION 3.07. 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
Securities registered in the name of the Depositary or the nominee of the
Depositary, the Company or the Company's agent shall, except as set forth
herein, have no obligations to the Beneficial Owners.

         SECTION 3.08. APPOINTMENT OF SUCCESSOR DEPOSITARY.

         If the Depositary elects to discontinue its services as securities
depositary with respect to the Securities, the Company may, in its sole
discretion, appoint a successor Depositary with respect to the Securities.

         SECTION 3.09. DEFINITIVE CERTIFICATES.

         If:

               (i)  the Depositary elects to discontinue its services as
         securities depositary with respect to the Securities and a successor
         Depositary is not appointed within 90 days after such discontinuance
         pursuant to Section 3.08; or

              (ii)  the Company elects, after consultation with the Purchase
         Contract Agent, to terminate the book-entry system for the Securities,

then (x) definitive Certificates shall be prepared by the Company with respect
to such Securities and delivered to the Purchase Contract Agent and (y) upon
surrender of the Global Certificates representing the Securities by the
Depositary, accompanied by registration instructions, the Company shall cause
definitive Certificates to be delivered to Beneficial Owners in accordance with
the instructions of the Depositary. The Company 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. Each definitive Certificate so
delivered shall evidence Securities of the same kind and tenor as the Global
Certificate so surrendered in respect thereof.

         SECTION 3.10. MUTILATED, DESTROYED, LOST AND STOLEN CERTIFICATES.

         If any mutilated Certificate is surrendered to the Purchase Contract
Agent, the Company shall execute and deliver to the Purchase Contract Agent, and
the Purchase Contract Agent shall authenticate, execute on behalf of the Holder,
and deliver in exchange therefor, a new Certificate, evidencing the same number
of Stock Purchase Units or Treasury Stock Purchase Units, as the case may be,
and bearing a Certificate number not contemporaneously outstanding.

                                      24

<Page>

         If there shall be delivered to the Company and the Purchase Contract
Agent (i) evidence to their satisfaction of the destruction, loss or theft of
any Certificate, and (ii) such security or indemnity 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 Purchase Contract Agent that such Certificate
has been acquired by a protected purchaser, the Company shall execute and
deliver to the Purchase Contract Agent, and the Purchase Contract 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 Stock Purchase Units or Treasury Stock Purchase
Units, as the case may be, and bearing a Certificate number not
contemporaneously outstanding.

         Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Purchase Contract Agent, and the Purchase Contract
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 earliest of any Early Settlement Date for such lost or
mutilated Certificate, the Purchase Contract Settlement Date or 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 Purchase Contract
Agent shall:

               (i)  if the Purchase Contract Settlement Date or an Early
         Settlement Date with respect to such lost or mutilated Certificate has
         occurred, deliver the shares of Common Stock issuable in respect of
         the Purchase Contracts forming a part of the Securities evidenced by
         such Certificate; or

              (ii)  if a Cash Settlement or an Early Settlement Date with
         respect to such lost or mutilated Certificate shall have occurred or
         if a Termination Event shall have occurred prior to the Purchase
         Contract Settlement Date, transfer the Preferred Securities, the
         [Subordinated] Notes, the Treasury Securities or the appropriate
         Applicable Ownership Interest (as specified in clause (A) of the
         definition of such term) of the Treasury Portfolio, as the case may
         be, evidenced thereby, in each case subject to the applicable
         conditions and in accordance with the applicable provisions of Section
         3.15 and Article Five hereof.

         Upon the issuance of any new Certificate under this Section, the
Company and the Purchase Contract Agent may require the payment by the Holder of
a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto and any other expenses (including the fees and
expenses of the Purchase Contract Agent) connected therewith.

         Every new Certificate issued pursuant to this Section in lieu of any
destroyed, lost or stolen Certificate shall constitute an original additional
contractual obligation of the Company and of the Holder in respect of the
Security evidenced thereby, whether or not the destroyed, lost or stolen
Certificate (and the Securities 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

                                      25

<Page>

proportionately with any and all other Certificates delivered hereunder.

         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.

         Prior to due presentment of a Certificate for registration of transfer,
the Company and the Purchase Contract Agent, and any agent of the Company or the
Purchase Contract Agent, may treat the Person in whose name such Certificate is
registered as the owner of the Security evidenced thereby, for the purpose of
receiving distributions on the Preferred Securities, the Treasury Securities,
the [Subordinated] Notes, or on the maturing quarterly interest strips of the
Treasury Portfolio, as applicable, receiving Purchase Contract Payments,
performance of the Purchase Contracts and for all other purposes whatsoever,
whether or not any distributions on the Preferred Securities, the Treasury
Securities, the [Subordinated] Notes, or Treasury Portfolio, as applicable, or
Purchase Contract Payments payable on the Purchase Contracts, each constituting
a part of the Security evidenced thereby shall be overdue and notwithstanding
any notice to the contrary, and neither the Company nor the Purchase Contract
Agent, nor any agent of the Company or the Purchase Contract Agent, shall be
affected by notice to the contrary.

         Notwithstanding the foregoing, with respect to any Global Certificate,
nothing contained herein shall prevent the Company, the Purchase Contract Agent
or any agent of the Company or the Purchase Contract Agent, from giving effect
to any written certification, proxy or other authorization furnished by the
Depositary (or its nominee), as a Holder, with respect to such Global
Certificate or impair, as between such Depositary and the related Beneficial
Owner, the operation of customary practices governing the exercise of rights of
the Depositary (or its nominee) as Holder of such Global Certificate.

         SECTION 3.12. CANCELLATION.

         All Certificates surrendered for delivery of shares of Common Stock on
or after the Purchase Contract Settlement Date, upon the transfer of Preferred
Securities, [Subordinated] Notes, the appropriate Applicable Ownership Interest
(as specified in clause (A) of the definition of that term) of the Treasury
Portfolio or Treasury Securities, as the case may be, after the occurrence of a
Termination Event or pursuant to an Early Settlement, or upon the registration
of transfer or exchange of a Security, or a Collateral Substitution or the
reestablishment of Stock Purchase Units shall, if surrendered to any Person
other than the Purchase Contract Agent, be delivered to the Purchase Contract
Agent and, if not already cancelled, shall be promptly cancelled by it. The
Company may at any time deliver to the Purchase Contract 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
Purchase Contract

                                      26

<Page>

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 Purchase Contract Agent shall be
disposed of in accordance with its customary practices.

         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 delivered to the Purchase
Contract Agent cancelled or for cancellation.

         SECTION 3.13. CREATION OF TREASURY STOCK PURCHASE UNITS BY
SUBSTITUTION OF TREASURY SECURITIES.

         Subject to the conditions set forth in this Agreement, a Holder may
separate the Preferred Securities or the [Subordinated] Notes, as applicable,
from the related Purchase Contracts in respect of such Holder's Stock Purchase
Units by substituting for such Preferred Securities or [Subordinated] Notes, as
applicable, Treasury Securities in an aggregate principal amount equal to the
aggregate liquidation amount of such Preferred Securities or the aggregate
principal amount of such [Subordinated] Notes, as applicable (a "COLLATERAL
SUBSTITUTION"), at any time from and after the date of this Agreement and prior
to or on the seventh Business Day immediately preceding the Purchase Contract
Settlement Date. To effect such substitution, the Holder must:

          (1)   deposit with the Securities Intermediary Treasury Securities
                having an aggregate principal amount equal to the aggregate
                liquidation amount of the Preferred Securities or the aggregate
                principal amount of the [Subordinated] Notes comprising part of
                such Stock Purchase Units, as the case may be; and

          (2)   transfer the related Stock Purchase Units to the Purchase
                Contract Agent accompanied by a notice to the Purchase Contract
                Agent, substantially in the form of Exhibit C hereto, (i)
                stating that the Holder has transferred the relevant amount of
                Treasury Securities to the Securities Intermediary and (ii)
                requesting that the Purchase Contract Agent instruct the
                Collateral Agent to release the Preferred Securities or the
                [Subordinated] Notes, as the case may be, underlying such Stock
                Purchase Units, whereupon the Purchase Contract Agent shall
                promptly provide an instruction to such effect to the Collateral
                Agent, substantially in the form of Exhibit A to the Pledge
                Agreement.

         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 cause the Securities
Intermediary to effect the release of such Preferred Securities or the
[Subordinated] Notes, as the case may be, from the Pledge, free and clear of the
Company's security interest therein, and the transfer of such Preferred
Securities or the [Subordinated] Notes, as the case

                                      27

may be, to the Purchase Contract Agent on behalf of the Holder. Upon receipt
thereof, the Purchase Contract Agent shall promptly:

               (i)  cancel the related Stock Purchase Units;

              (ii)  transfer the Preferred Securities or the [Subordinated]
         Notes, as the case may be, to the Holder; and

             (iii)  authenticate, execute on behalf of such Holder and deliver a
         Treasury Stock Purchase Units Certificate executed by the Company in
         accordance with Section 3.03 evidencing the same number of Purchase
         Contracts as were evidenced by the cancelled Stock Purchase Units.

         Holders who elect to separate the Preferred Securities or the
[Subordinated] Notes, as the case may be, from the related Purchase Contracts
and to substitute Treasury Securities for such Preferred Securities or the
[Subordinated] Notes, as the case may be, 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.

         Holders may make Collateral Substitutions only in integral multiples of
40 Stock Purchase Units. If a Tax Event Redemption has occurred, Holders may no
longer convert their Stock Purchase Units into Treasury Stock Purchase Units.

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

         Except as described in this Section 3.13 or in connection with a Cash
Settlement, for so long as the Purchase Contract underlying a Stock Purchase
Unit remains in effect, such Stock Purchase Unit shall not be separable into its
constituent parts, and the rights and obligations of the Holder in respect of
the Preferred Securities or the [Subordinated] Notes, as the case may be, and
the Purchase Contract comprising such Stock Purchase Unit may be acquired, and
may be transferred and exchanged, only as a Stock Purchase Unit.

         SECTION 3.14. REESTABLISHMENT OF STOCK PURCHASE UNITS.

         Subject to the conditions set forth in this Agreement, a Holder of
Treasury Stock Purchase Units may reestablish Stock Purchase Units at any time
(i) prior to or on the seventh Business Day immediately preceding the Purchase
Contract Settlement Date, by:

          (1)   depositing with the Securities Intermediary Preferred Securities
                or [Subordinated] Notes, as the case may be, having an aggregate
                liquidation amount (in the case of Preferred Securities) or
                aggregate principal amount (in the case of [Subordinated]
                Notes), as the case may be, equal to the aggregate principal
                amount at maturity of the Treasury Securities comprising part of
                the Treasury Stock Purchase Units; and

          (2)   transferring the related Treasury Stock Purchase Units to the
                Purchase Contract Agent accompanied by a notice to the Purchase
                Contract Agent, substantially in the form of Exhibit C hereto,
                (i) stating that the Holder has transferred the relevant amount
                of Preferred Securities or [Subordinated] Notes, as the case may
                be, to the Securities Intermediary and (ii) requesting that the
                Purchase Contract Agent instruct the Collateral Agent to release
                the Treasury Securities underlying such Treasury Stock Purchase
                Units, whereupon the Purchase Contract Agent shall promptly
                provide an instruction to such effect to the Collateral Agent,
                substantially in the form of Exhibit C to the Pledge Agreement.

Upon receipt of the Preferred Securities or the [Subordinated] Notes, as the
case may be, 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 cause the Securities Intermediary to effect the release of
the Treasury Securities having a corresponding aggregate principal amount at
maturity from the Pledge, free and clear of the Company's security interest
therein, and the transfer to the Purchase Contract Agent on behalf of the
Holder. Upon receipt thereof, the Purchase Contract Agent shall promptly:

              (i)   cancel the related Treasury Stock Purchase Units;

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

              (iii) authenticate, execute on behalf of such Holder and deliver a
         Stock Purchase Units Certificate executed by the Company in accordance
         with Section 3.03 evidencing the same number of Purchase Contracts as
         were evidenced by the cancelled Treasury Stock Purchase Units.

         Holders who elect to reestablish Stock Purchase Units shall be
responsible for any fees or expenses payable to the Collateral Agent for its
services as Collateral Agent in respect of the

                                      29

<Page>

reestablishment, and the Company shall not be responsible for any such fees or
expenses.

         Holders of Treasury Stock Purchase Units may only reestablish Stock
Purchase Units in integral multiples of 40 Treasury Stock Purchase Units. If a
Tax Event Redemption has occurred, Holders may no longer convert their Treasury
Stock Purchase Units into Stock Purchase Units.

         Except as provided in this Section 3.14 or in connection with a Cash
Settlement, for so long as the Purchase Contract underlying a Treasury Stock
Purchase Unit remains in effect, such Treasury Stock Purchase Unit shall not be
separable into its constituent parts and the rights and obligations of the
Holder of such Treasury Stock Purchase Unit in respect of the 1/40 of a
Treasury Security and the Purchase Contract comprising such Treasury Stock
Purchase Unit may be acquired, and may be transferred and exchanged, only as a
Treasury Stock Purchase Unit.

         SECTION 3.15. TRANSFER OF COLLATERAL UPON OCCURRENCE OF TERMINATION
EVENT.

         Upon the occurrence of a Termination Event and the transfer to the
Purchase Contract Agent of the Preferred Securities, [Subordinated] Notes, the
appropriate Applicable Ownership Interest of the Treasury Portfolio or the
Treasury Securities, as the case may be, underlying the Stock Purchase Units and
the Treasury Stock Purchase Units, as the case may be, pursuant to the terms of
the Pledge Agreement, the Purchase Contract Agent shall request transfer
instructions with respect to such Preferred Securities, [Subordinated] Notes,
the appropriate Applicable Ownership Interest of the Treasury Portfolio or
Treasury Securities, as the case may be, from each Holder by written request,
substantially in the form of Exhibit D hereto, mailed to such Holder at its
address as it appears in the Security Register.

         Upon book-entry transfer of the Stock Purchase Units or the Treasury
Stock Purchase Units or delivery of a Stock Purchase Units Certificate or
Treasury Stock Purchase Units Certificate to the Purchase Contract Agent with
such transfer instructions, the Purchase Contract Agent shall transfer the
Preferred Securities, [Subordinated] Notes, the appropriate Applicable Ownership
Interest of the Treasury Portfolio or Treasury Securities, as the case may be,
underlying such Stock Purchase Units or Treasury Stock Purchase 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 of Stock
Purchase Units or Treasury Stock Purchase Units fails to effect such transfer or
delivery, the Preferred Securities, [Subordinated] Notes, the appropriate
Applicable Ownership Interest of the Treasury Portfolio or Treasury Securities,
as the case may be, underlying such Stock Purchase Units or Treasury Stock
Purchase Units, as the case may be, and any distributions thereon, shall be held
in the name of the Purchase Contract Agent or its nominee in trust for the
benefit of such Holder, until the earlier to occur of:

              (i) the transfer of such Stock Purchase Units or Treasury Stock
         Purchase Units or surrender of the Stock Purchase Units Certificate or
         Treasury Stock Purchase Units Certificate

                                      30

<Page>

         or receipt by the Company and the Purchase Contract Agent from such
         Holder of satisfactory evidence that such Stock Purchase Units
         Certificate or Treasury Stock Purchase Units Certificate has been
         destroyed, lost or stolen, together with any indemnity that may be
         required by the Purchase Contract 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 a Security, 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 or its
trustee, receiver, liquidator or a person or entity performing similar functions
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.

     THE PREFERRED SECURITIES, [SUBORDINATED] NOTES AND APPLICABLE OWNERSHIP
                       INTEREST OF THE TREASURY PORTFOLIO

         SECTION 4.01. INTEREST PAYMENTS; RIGHTS TO INTEREST PAYMENTS PRESERVED.

         Any distribution on any Preferred Security, any [Subordinated] Note or
on the appropriate Applicable Ownership Interest of the Treasury Portfolio, as
the case may be, which is paid on any Payment Date shall, subject to receipt
thereof by the Purchase Contract Agent from the Collateral Agent as provided by
the terms of the Pledge Agreement, be paid to the Person in whose name the Stock
Purchase Units Certificate (or one or more Predecessor Stock Purchase Units
Certificates) of which such Preferred Security, such [Subordinated] Note or the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, is registered at the close of business on the Record Date for such
Payment Date. Any such distribution shall be subject to deferral at the option
of the Company in accordance with the Indenture and the Declaration.

         Each Stock Purchase Units Certificate evidencing Preferred Securities,
[Subordinated] Notes or the appropriate Applicable Ownership Interest of the
Treasury Portfolio delivered under this Agreement upon registration of transfer
of or in exchange for or in lieu of any other Stock Purchase Units Certificate
shall carry the right to distributions accrued and unpaid, and to accrue
distributions interest, which were carried by the Preferred Securities,
[Subordinated] Notes or the appropriate Applicable Ownership Interest of the
Treasury Portfolio underlying such other Stock Purchase Units Certificate.

                                      31

<Page>

         In the case of any Stock Purchase Units with respect to which Cash
Settlement of the underlying Purchase Contract is properly effected pursuant to
Section 5.02 hereof, or with respect to which Early Settlement of the underlying
Purchase Contract is properly effected pursuant tot Section 5.07 hereof, or with
respect to which a Collateral Substitution is effected, in each case on a date
that is after any Record Date and prior to or on the next succeeding Payment
Date, distributions on the Preferred Securities, [Subordinated] Notes or on the
appropriate Applicable Ownership Interest of the Treasury Portfolio, as the case
may be, underlying such Stock Purchase Unit otherwise payable on such Payment
Date shall be payable on such Payment Date notwithstanding such Cash Settlement
or Early Settlement or Collateral Substitution, and such distributions shall,
subject to receipt thereof by the Purchase Contract Agent, be payable to the
Person in whose name the Stock Purchase Units Certificate (or one or more
Predecessor Stock Purchase 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 Stock Purchase Unit with
respect to which Cash Settlement or Early Settlement of the underlying Purchase
Contract is properly effected, or with respect to which a Collateral
Substitution has been effected, distributions on the related Preferred
Securities, [Subordinated] Notes or the appropriate Applicable Ownership
Interest of the Treasury Portfolio, as the case may be, that would otherwise be
payable after the Purchase Contract Settlement Date, Early Settlement Date or
the date of the Collateral Substitution, as the case may be, shall not be
payable hereunder to the Holder of such Stock Purchase Units; PROVIDED, HOWEVER,
that to the extent that such Holder continues to hold separated Preferred
Securities or [Subordinated] Notes that formerly comprised a part of such
Holder's Stock Purchase Unit, such Holder shall be entitled to receive
distributions on such separated Preferred Securities or [Subordinated] Notes.

         Not later than 15 calendar days nor more than 30 calendar days prior to
the Remarketing Date, the Company shall request the Depositary to notify the
Beneficial Owners or Depositary Participants holding Securities of the
procedures to be followed by Holders of Securities who intend to effect a Cash
Settlement.

         SECTION 4.02. NOTICE AND VOTING.

         Under the terms of the Pledge Agreement, the Purchase Contract Agent
will be entitled to exercise the voting and any other consensual rights
pertaining to the Pledged Preferred Securities or Pledged [Subordinated] Notes,
but only to the extent instructed in writing by the Holders as described below.
Upon receipt of notice of any meeting at which holders of Preferred Securities
or [Subordinated] Notes are entitled to vote or upon any solicitation of
consents, waivers or proxies of holders of Preferred Securities or
[Subordinated] Notes, the Purchase Contract Agent shall, as soon as practicable
thereafter, mail, first class, postage pre-paid, to the Holders of Stock
Purchase Units a notice:

              (i)   containing such information as is contained in the notice or
         solicitation;

                                      32

<Page>

              (ii)  stating that each Holder on the record date set by the
         Purchase Contract Agent therefor (which, to the extent possible, shall
         be the same date as the record date for determining the holders of
         Preferred Securities or [Subordinated] Notes, as the case may be,
         entitled to vote) shall be entitled to instruct the Purchase Contract
         Agent as to the exercise of the voting rights pertaining to such
         Preferred Securities or [Subordinated] Notes underlying their Stock
         Purchase Units; and

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

Upon the written request of the Holders of Stock Purchase Units on such record
date received by the Purchase Contract Agent at least six days prior to such
meeting, the Purchase Contract 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 Preferred Securities or [Subordinated] Notes, as
the case may be, as to which any particular voting instructions are received. In
the absence of specific instructions from the Holder of a Stock Purchase Unit,
the Purchase Contract Agent shall abstain from voting the Preferred Securities
or [Subordinated] Notes underlying such Stock Purchase Unit. The Company hereby
agrees, if applicable, to solicit Holders of Stock Purchase Units to timely
instruct the Purchase Contract Agent in order to enable the Purchase Contract
Agent to vote such Preferred Securities or [Subordinated] Notes and the Trust
shall covenant to this effect in the Declaration.

         SECTION 4.03. DISTRIBUTION OF [SUBORDINATED] NOTES; TAX EVENT
REDEMPTION.

         Upon the dissolution and liquidation of the Trust in accordance with
the Declaration, an aggregate principal amount at maturity of [Subordinated]
Notes constituting the assets of the Trust and underlying the Preferred
Securities equal to the aggregate liquidation amount of the Pledged Preferred
Securities shall be delivered to the Securities Intermediary in exchange for the
Pledged Preferred Securities. Thereafter, the [Subordinated] Notes will be
substituted for the Pledged Preferred Securities as the Collateral, and will be
held by the Securities Intermediary in the Collateral Account in accordance with
the terms of the Pledge Agreement to secure the obligations of each Holder of a
Stock Purchase Unit to purchase the Common Stock of the Company under the
Purchase Contracts constituting a part of such Stock Purchase Unit.

         Notwithstanding the foregoing, in the event of a dissolution and
liquidation of the Trust, if a Liquidation Distribution is to be distributed in
lieu of the [Subordinated] Notes as provided for in the Declaration, an amount
equal to the Liquidation Distribution shall be deposited in the Collateral
Account in exchange for the Pledged Preferred Securities. Thereafter, pursuant
to the terms of the Pledge Agreement, the Collateral Agent shall cause the
Securities Intermediary to apply an amount equal to the Redemption Amount of
such Liquidation Distribution to purchase on behalf of the Holders of Stock
Purchase Units the Treasury Portfolio and promptly remit the remaining portion
of such Liquidation Distribution to the Purchase Contract Agent for payment to
the Holders of such Stock Purchase Units. The Applicable Ownership Interest (as
specified in clause (A) of the definition of such

                                      33

<Page>

term) of the Treasury Portfolio will be substituted as Collateral for the
Pledged Preferred Securities and will be held by the Collateral Agent in
accordance with the terms of the Pledge Agreement to secure the obligation of
each Holder of a Stock Purchase Unit to purchase the Common Stock of the
Company under the Purchase Contract constituting a part of such Stock Purchase
Unit.

         Following the dissolution and liquidation of the Trust, the Holders and
the Collateral Agent shall have such security interests, rights and obligations
with respect to the [Subordinated] Notes or the Applicable Ownership Interest
(as specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as the case may be, as the Holders and the Collateral Agent had in
respect of the Preferred Securities subject to the Pledge thereof as provided in
the Pledge Agreement. The Company may cause to be made in any Stock Purchase
Unit Certificates thereafter to be issued such change in phraseology and form
(but not in substance) as may be appropriate to reflect the dissolution and
liquidation of the Trust and the substitution of [Subordinated] Notes or the
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio, as the case may be, for Preferred
Securities as Collateral.

         Upon the occurrence of a Tax Event Redemption prior to the Purchase
Contract Settlement Date, an amount equal to the Redemption Amount, plus any
accumulated and unpaid distributions or accrued and unpaid interest, as the case
may be, payable on the Tax Event Redemption Date with respect to the Applicable
Principal Amount shall be deposited in the Collateral Account in exchange for
the Pledged Preferred Securities or the Pledged [Subordinated] Notes, as the
case may be. Thereafter, pursuant to the terms of the Pledge Agreement, the
Collateral Agent shall cause the Securities Intermediary to apply an amount
equal to the Redemption Amount of such funds to purchase on behalf of the
Holders of Stock Purchase Units the Treasury Portfolio and promptly remit the
remaining portion of such funds to the Purchase Contract Agent for payment to
the Holders of such Stock Purchase Units. The Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio will be substituted as Collateral for the Pledged Preferred Securities
or the Pledged [Subordinated] Notes, as the case may be, and will be held by the
Collateral Agent in accordance with the terms of the Pledge Agreement to secure
the obligation of each Holder of a Stock Purchase Unit to purchase the Common
Stock of the Company under the Purchase Contract constituting a part of such
Stock Purchase Unit. Following the occurrence of a Tax Event Redemption prior to
the Purchase Contract Settlement Date, the Holders of Stock Purchase Units and
the Collateral Agent shall have such security interest rights and obligations
with respect to the Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio as the Holders of Stock
Purchase Units and the Collateral Agent had in respect of the Preferred
Securities or [Subordinated] Notes, as the case may be, subject to the Pledge
thereof as provided in the Pledge Agreement, and any reference herein to the
Preferred Securities or the [Subordinated] Notes shall be deemed to be reference
to such Treasury Portfolio. The Company may cause to be made in any Stock
Purchase Unit Certificates thereafter to be issued such change in phraseology
and form (but not in substance) as may be appropriate to reflect the liquidation
of the Trust and the substitution of the Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury

                                      34

Portfolio for Preferred Securities or [Subordinated] Notes as Collateral.

there shall have occurred a Termination Event with respect to the Security of
which such Purchase Contract is a part. The "SETTLEMENT RATE" is equal to:

              (i)   if the Applicable Market Value (as defined below) is greater
         than or equal to $______ (the "THRESHOLD APPRECIATION PRICE"), _______
         share of Common Stock per Purchase Contract;

              (ii)  if the Applicable Market Value is less than the Threshold
         Appreciation Price but greater than $_______ (the "REFERENCE PRICE"),
         the number of shares of Common Stock per Purchase Contract having a
         value, based on the Applicable Market Value, equal to the Stated
         Amount; and

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

in each case subject to adjustment as provided in Section 5.04 (and in each case
rounded upward or downward to the nearest 1/10,000th of a share).

         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 Purchase Contract Settlement
Date.

         The "CLOSING PRICE" per share of Common Stock on any date of
determination means:

              (i)   the closing sale price as of the 4:15 p.m. close of the
         principal trading session (or, if no closing price is reported, the
         last reported sale price) per share on the New York Stock Exchange,
         Inc. (the "NYSE") on such date;

                                      35

<Page>

              (ii)  if the Common Stock is not listed for trading on the NYSE on
         any such date, the closing sale price per share 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, the closing sale price per
         share as reported by The Nasdaq National 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 average of the
         mid-point of the last bid and ask prices of the Common Stock on such
         date from at least three nationally recognized independent investment
         banking firms retained for this purpose by the Company.

         A "TRADING DAY" means a day on which the Common Stock (1) 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 (2) 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 Holder of a Stock Purchase Unit or a Treasury Stock Purchase Unit,
by its acceptance thereof:

              (i)   irrevocably authorizes the Purchase Contract 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);

              (ii)  agrees to be bound by the terms and provisions thereof;

              (iii) covenants and agrees to perform its obligations under such
         Purchase Contracts;

              (iv)  consents to the provisions hereof;

              (v)   irrevocably authorizes the Purchase Contract Agent to enter
         into and perform this Agreement and the Pledge Agreement on its behalf
         as its attorney-in-fact; and

              (vi)  consents to, and agrees to be bound by, the Pledge of such
         Holder's right, title and interest in and to the Collateral Account,
         including the Preferred Securities, [Subordinated] Notes, the
         Applicable Ownership Interest (as specified in clause (A) of the
         definition of such

                                      36

<Page>

         term) of the Treasury Portfolio or the Treasury Securities pursuant
         to the Pledge Agreement,

PROVIDED that upon a Termination Event, the rights of the Holder of such
Security under the Purchase Contract may be enforced without regard to any other
rights or obligations. Each Holder of a Stock Purchase Unit or a Treasury Stock
Purchase Unit, by its acceptance thereof, further covenants and agrees, that to
the extent and in the manner provided in Section 5.02 and the Pledge Agreement,
but subject to the terms thereof, payments in respect of the Preferred
Securities or the [Subordinated] Notes or the proceeds from the Treasury
Securities or the Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio at maturity on the
Purchase Contract Settlement Date, as the case may be, shall be paid 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.

         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)
by the terms of this Agreement, the Purchase Contracts underlying such
Certificate, the Declaration and the Pledge Agreement and the transferor shall
be released from the obligations under this Agreement, the Purchase Contracts
underlying the Certificate so transferred and the Pledge Agreement. The Company
covenants and agrees, and each Holder of a Certificate, by its acceptance
thereof, likewise covenants and agrees, to be bound by the provisions of this
paragraph.

         SECTION 5.02. PAYMENT OF PURCHASE PRICE.

          (a) (i)   Unless a Tax Event Redemption has occurred or a Holder of a
Stock Purchase Unit effects an Early Settlement of the underlying Purchase
Contract in the manner described in Section 5.07, each Holder who intends to pay
in cash to satisfy such Holder's obligations under the Purchase Contract on the
Purchase Contract Settlement Date shall notify the Purchase Contract Agent by
use of a notice in substantially the form of Exhibit E hereto of his intention
to pay in cash ("CASH SETTLEMENT") the Purchase Price for the shares of Common
Stock to be purchased pursuant to the related Purchase Contract. Such notice
shall be given prior to 5:00 p.m. (New York City time) on the seventh Business
Day immediately preceding the Purchase Contract Settlement Date. Prior to 11:00
a.m. (New York City time) on the next succeeding Business Day, the Purchase
Contract Agent shall notify the Collateral Agent and the Property Trustee or the
Indenture Trustee, as the case may be, of the receipt of such notices from
Holders intending to make a Cash Settlement.

              (ii)  A Holder of a Stock Purchase Unit who has so notified the
         Purchase Contract Agent of his intention to effect a Cash Settlement in
         accordance with paragraph 5.02(a)(i) above shall pay the Purchase Price
         to the Securities Intermediary for deposit in the Collateral Account
         prior to 11:00 a.m. (New York City time) on the fifth Business Day
         immediately preceding the Purchase Contract Settlement Date, in lawful
         money of the United States by certified or cashiers' check or wire
         transfer, in each case in immediately available funds payable

                                      37

<Page>

         to or upon the order of the Securities Intermediary. Any cash received
         by the Collateral Agent shall be invested promptly by the Securities
         Intermediary in Permitted Investments and paid to the Company on the
         Purchase Contract Settlement Date in settlement of the Purchase
         Contracts in accordance with the terms of this Agreement and the Pledge
         Agreement. Any funds received by the Securities Intermediary in respect
         of the investment earnings from such Permitted Investments in excess of
         the Purchase Price for the shares of Common Stock to be purchased by
         such Holder shall be distributed to the Purchase Contract Agent when
         received for payment to the Holder.

              (iii) If a Holder of a Stock Purchase Unit fails to notify the
         Purchase Contract Agent of his intention to make a Cash Settlement in
         accordance with paragraph 5.02(a)(i) above, or does notify the Purchase
         Contract Agent as provided in paragraph 5.02(a)(i) above of his
         intention to pay the Purchase Price in cash, but fails to make such
         payment as required by paragraph 5.02(a)(ii) above, such Holder shall
         be deemed to have consented to the disposition of the Pledged Preferred
         Securities or the Pledged [Subordinated] Notes pursuant to the
         Remarketing as described in paragraph 5.02(b) below.

              (iv)  Promptly after 11:00 a.m. (New York City time) on the fifth
         Business Day preceding the Purchase Contract Settlement Date, the
         Purchase Contract Agent, based on notices received by the Purchase
         Contract Agent pursuant to Section 5.02(a) hereof and notice from the
         Securities Intermediary regarding cash received by it prior to such
         time, shall notify the Collateral Agent and the Property Trustee or the
         Indenture Trustee, as applicable of the aggregate number of Preferred
         Securities or [Subordinated] Notes to be tendered for purchase in the
         Remarketing in a notice substantially in the form of Exhibit F hereto.

          (b) In order to dispose of the Preferred Securities or [Subordinated]
Notes, Stock Purchase Units Holders who have not notified the Purchase Contract
Agent of their intention to effect a Cash Settlement as provided in paragraph
5.02(a)(i) above, or who have so notified the Purchase Contract Agent but failed
to make such payment as required by paragraph 5.02(a)(ii) above, the Company
shall engage _____________________, as Remarketing Agent (the "REMARKETING
AGENT"), pursuant to the Remarketing Agreement (and subject to removal as
provided in the Remarketing Agreement) to sell such Preferred Securities or
[Subordinated] Notes. In order to facilitate the Remarketing, the Purchase
Contract Agent, based on the notices specified in Section 5.02(a)(iv), shall
notify the Remarketing Agent, promptly after 11:00 a.m. (New York City time) on
the fifth Business Day immediately preceding the Purchase Contract Settlement
Date, of the aggregate number of Preferred Securities or [Subordinated] Notes
that are part of Stock Purchase Units to be remarketed. Concurrently, the
Collateral Agent, pursuant to the terms of the Pledge Agreement, shall cause
such Preferred Securities or [Subordinated] Notes to be presented to the
Remarketing Agent for Remarketing.

         Upon receipt of such notice from the Purchase Contract Agent and such
Preferred Securities or [Subordinated] Notes, the Remarketing Agent shall, on
the third Business Day immediately preceding

                                      38

<Page>

the Purchase Contract Settlement Date, use reasonable efforts to remarket such
Preferred Securities or [Subordinated] Notes on such date at a price equal to
[     ]% of the Stated Amount ($[     ]) per Preferred Security or
[Subordinated] Note, as provided in the Remarketing Agreement. The proceeds
from the Remarketing shall be invested by the Collateral Agent in Permitted
Investments, in accordance with the Pledge Agreement, and then applied to
satisfy in full such Stock Purchase Units Holders' obligations to pay the
Purchase Price for the shares of Common Stock under the related Purchase
Contracts on the Purchase Contract Settlement Date. In addition, [$     ] per
Preferred Security or [Subordinated] Note of the proceeds shall automatically
be remitted to the Remarketing Agent for services rendered in connection with
the Remarketing (the "REMARKETING FEE").

         If, in spite of using its reasonable efforts, the Remarketing Agent
cannot remarket the related Preferred Securities or [Subordinated] Notes of
such Holders of Stock Purchase Units at a price equal to [     ]% of the Stated
Amount ($[     ]), then the Remarketing Agent shall increase the distribution
rate on the Preferred Securities or the interest rate on the [Subordinated]
Notes, as the case may be, so that the market value of such Preferred
Securities will equal ($[     ]). If the Remarketing Agent determines that it
will be able to remarket the related Preferred Securities or [Subordinated]
Notes of such Holders of Stock Purchase Units at a price in excess of [     ]%
of the Stated Amount ($[     ]), then the Remarketing Agent shall decrease the
distribution rate on the Preferred Securities or the interest rate on the
[Subordinated] Notes, as the case may be, so that the market value of such
Preferred Securities or [Subordinated] Notes will be equal to [$     ]. If the
Remarketing Agent cannot Remarket the Preferred Securities or the [Subordinated]
Notes, as the case may be, after such increase or decrease, the Remarketing
shall be deemed to have failed (a "FAILED REMARKETING"), an event of default
shall be deemed to have occurred under this Agreement and the Pledge Agreement
and in accordance with the terms of the Pledge Agreement, the Collateral Agent,
for the benefit of the Company, shall exercise its rights as a secured party
with respect to such Preferred Securities or [Subordinated] Notes, including
those actions specified in paragraph 5.02(c) below; PROVIDED, that if upon a
Failed Remarketing the Collateral Agent exercises such rights for the benefit
of the Company with respect to such Preferred Securities or [Subordinated]
Notes, any accrued and unpaid distributions on such Preferred Securities or
[Subordinated] Notes and any accrued and unpaid Purchase Contract Payments
(including any deferred Purchase Contract Payments) shall become payable by the
Company to the Purchase Contract Agent for payment to the Beneficial Owner of
the Stock Purchase Units to which such Preferred Securities or [Subordinated]
Notes relate. The Company shall cause a notice of such Failed Remarketing to be
published on the second Business Day immediately preceding the Purchase
Contract Settlement Date 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, and on Bloomberg News.

         (c)   With respect to any Preferred Securities or [Subordinated] Notes
which are subject to a Failed Remarketing, 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 paragraph 5.02(g) below, shall, in
full satisfaction of the Holders' obligations under the Purchase Contracts among
other things, (i) retain

                                      39
<Page>

the Preferred Securities or [Subordinated] Notes, (ii) sell the Preferred
Securities or [Subordinated] Notes in one or more public or private sales or
(iii) take, or choose not to take, any other action with respect to the
Preferred Securities or the [Subordinated] Notes, which in every case specified
in (i), (ii) and (iii) shall constitute payment in full for the aggregate
Purchase Price for the shares of Common Stock to be purchased under the
Purchase Contracts.

         (d)  (i)  Unless a Holder of a Treasury Stock Purchase Unit or Stock
Purchase Unit (if a Tax Event Redemption has occurred) effects an Early
Settlement of the underlying Purchase Contract through the early delivery of
cash to the Purchase Contract Agent in the manner described in Section 5.07,
each Holder of a Treasury Stock Purchase Unit or Stock Purchase Unit (if a Tax
Event Redemption has occurred) who intends to pay in cash shall notify the
Purchase Contract Agent by use of a notice in substantially the form of Exhibit
E hereto of his intention to pay in cash the Purchase Price for the shares of
Common Stock to be purchased pursuant to the related Purchase Contract. Such
notice shall be given prior to 5:00 p.m. (New York City time) on the second
Business Day immediately preceding the Purchase Contract Settlement Date. Prior
to 11:00 a.m. (New York City time) on the next succeeding Business Day, the
Purchase Contract Agent shall notify the Collateral Agent of the receipt of
such notices from such Holders intending to make a Cash Settlement. Treasury
Stock Purchase Unit holders may make Cash Settlements only in integral
multiples of 40 Treasury Stock Purchase Units.

              (ii)  A Holder of a Treasury Stock Purchase Unit or Stock
         Purchase Units (if a Tax Event Redemption has occurred) who has so
         notified the Purchase Contract Agent of his intention to make a Cash
         Settlement in accordance with paragraph 5.02(d)(i) above shall pay the
         Purchase Price to the Securities Intermediary for deposit in the
         Collateral Account prior to 11:00 a.m. (New York City time) on the
         Business Day immediately preceding the Purchase Contract Settlement
         Date, in lawful money of the United States by certified or cashiers'
         check or wire transfer, in each case in immediately available funds
         payable to or upon the order of the Securities Intermediary. Any cash
         received by the Collateral Agent shall be invested promptly by the
         Securities Intermediary in Permitted Investments and paid to the
         Company on the Purchase Contract Settlement Date in settlement of the
         Purchase Contract in accordance with the terms of this Agreement and
         the Pledge Agreement. Any funds received by the Securities
         Intermediary in respect of the investment earnings from the investment
         in such Permitted Investments in excess of the Purchase Price for the
         shares of Common Stock to be purchased by such Holder shall be
         distributed to the Purchase Contract Agent when received for payment
         to the Holder.

             (iii)  If a Holder of a Treasury Stock Purchase Unit or Holder of a
         Stock Purchase Unit (if a Tax Event Redemption has occurred) fails to
         notify the Purchase Contract Agent of his intention to make a Cash
         Settlement in accordance with paragraph 5.02(d)(i) above, or does
         notify the Purchase Contract Agent as provided in paragraph 5.02(d)(i)
         above of his intention to pay the Purchase Price in cash, but fails to
         make such payment as required by

                                      40
<Page>

         paragraph 5.02(d)(ii) above, then upon the maturity of the Pledged
         Treasury Securities or the appropriate Applicable Ownership Interest
         (as specified in clause (A) of the definition of such term) of the
         Treasury Portfolio held by the Securities Intermediary on the Business
         Day immediately preceding the Purchase Contract Settlement Date, the
         principal amount of the Treasury Securities or the appropriate
         Applicable Ownership Interest (as specified in clause (A) of the
         definition of such term) of the Treasury Portfolio received by the
         Securities Intermediary shall be invested promptly in Permitted
         Investments. On the Purchase Contract Settlement Date, an amount equal
         to the Purchase Price shall be remitted to the Company as payment
         thereof without receiving any instructions from the Holder. In the
         event the sum of the proceeds from the related Pledged Treasury
         Securities or the appropriate Applicable Ownership Interest (as
         specified in clause (A) of the definition of such term) of the
         Treasury Portfolio and the investment earnings earned from such
         investments is in excess of the aggregate Purchase Price of the
         Purchase Contracts being settled thereby, the Collateral Agent shall
         cause the Securities Intermediary to distribute such excess to the
         Purchase Contract Agent for the benefit of the Holder of the related
         Treasury Stock Purchase Unit or Stock Purchase Unit when received.

              (iv)  A holder of a Preferred Security or [Subordinated] Note that
         is no longer part of a Stock Purchase Unit may elect to have such
         Preferred Security or [Subordinated] Note, as the case may be,
         remarketed. A holder making such an election must notify the Property
         Trustee or the Indenture Trustee, as the case may be, prior to 11:00
         a.m. (New York City time) on the fifth Business Day immediately
         preceding the Purchase Contract Settlement Date, of the aggregate
         number of Preferred Securities or [Subordinated] Notes, as the case
         may be, that are not part of Stock Purchase Units to be remarketed.
         Any such notice will be irrevocable and may not be conditioned upon
         the level at which the Reset Rate is established in the Remarketing.
         Concurrently, the Property Trustee or the Indenture Trustee, as the
         case may be, shall cause such Preferred Securities or [Subordinated]
         Notes, as the case may be, to be presented to the Remarketing Agent
         for Remarketing.

         (e) Any distribution to Holders of any payments described above shall
be payable at the office of the Purchase Contract Agent in New York City
maintained for that purpose or, at the option of the Holder, by check mailed to
the address of the Person entitled thereto at such address as it appears on the
Security Register.

         (f)   Upon Cash Settlement of any Purchase Contract:

               (i)  the Collateral Agent will in accordance with the terms of
         the Pledge Agreement cause the Pledged Preferred Securities, Pledged
         [Subordinated] Notes, the appropriate Applicable Ownership Interest (as
         specified in clause (A) of the definition of such term) of the Treasury
         Portfolio or the Pledged Treasury Securities, as the case may be,
         underlying the relevant Security to be released from the Pledge, free
         and clear of any security interest of the

                                      41
<Page>

         Company, and transferred to the Purchase Contract Agent for delivery
         to the Holder thereof or its designee as soon as practicable; and

              (ii)  subject to the receipt thereof, the Purchase Contract Agent
         shall, by book-entry transfer or other appropriate procedures, in
         accordance with written instructions provided by the Holder thereof,
         transfer such Preferred Securities, [Subordinated] Notes, or the
         appropriate Applicable Ownership Interest (as specified in clause (A)
         of the definition of such term) of the Treasury Portfolio or such
         Treasury Securities, as the case may be (or, if no such instructions
         are given to the Purchase Contract Agent by the Holder, the Purchase
         Contract Agent shall hold such Preferred Securities, [Subordinated]
         Notes, or the appropriate Applicable Ownership Interest (as specified
         in clause (A) of the definition of such term) of the Treasury
         Portfolio or such Treasury Securities, as the case may be, and any
         interest payment thereon, in the name of the Purchase Contract Agent
         or its nominee in trust for the benefit of such Holder until the
         expiration of the time period specified in the abandoned property laws
         of the relevant state).

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

         (h) The Company shall not be obligated to issue any shares of Common
Stock in respect of a Purchase Contract or deliver any certificates thereof to
the Holder of the related Security unless the Company shall have received
payment in full for the aggregate Purchase Price for the Common Stock to be
purchased thereunder in the manner herein set forth.

         SECTION 5.03.  ISSUANCE OF SHARES OF COMMON STOCK.

         Unless a Termination Event or an Early Settlement shall have occurred,
subject to Section 5.04(b), on the Purchase Contract Settlement Date upon
receipt of the aggregate Purchase Price payable on all Outstanding Securities,
the Company shall issue and deposit with the Purchase Contract Agent, for the
benefit of the Holders of the Outstanding Securities, one or more certificates
representing newly issued shares of Common Stock registered in the name of the
Purchase Contract Agent (or its nominee) as custodian for the Holders (such
certificates 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 Purchase Contract Settlement 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
Purchase Contract Agent on or after the Purchase Contract Settlement Date or
Early Settlement Date, as the case may be, together

                                      42
<Page>

with settlement instructions thereon duly completed and executed, the Holder of
such Certificate shall be entitled to receive forthwith in exchange therefor a
certificate representing that number of newly issued whole shares of Common
Stock which such Holder is entitled to receive pursuant to the provisions of
this Article Five (after taking into account all Securities then held by such
Holder), together with cash in lieu of fractional shares as provided in Section
5.09 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 Purchase Contract 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 the
Certificate evidencing such Purchase Contract or has established to the
satisfaction of the Company that such tax either has been paid or is not
payable.

         SECTION 5.04.  ADJUSTMENT OF SETTLEMENT RATE.

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

         (1)   In case the Company shall pay or make a dividend or other
distribution on Common Stock in Common Stock, the Settlement Rate in effect at
the opening of business on the day following the date fixed for the
determination of shareholders entitled to receive such dividend or other
distribution shall be increased by dividing such Settlement Rate by a fraction
of which:

               (i)  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

              (ii)  the denominator shall be the sum of such number of shares
         and the total number of shares constituting such dividend or other
         distribution,

such increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. For the purposes of
this paragraph (1), the number of shares of Common 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 pay any dividend or
make any distribution on shares of Common Stock held in the treasury of the
Company.

         (2)   In case the Company shall issue rights, warrants or options to
all holders of its Common Stock (not being available on an equivalent basis to
Holders of the Securities upon settlement of the Purchase Contracts underlying
such Securities) entitling them, for a period expiring within 45 days after

                                      43
<Page>

the record date for the determination of shareholders entitled to receive such
rights, warrants or options, to subscribe for or purchase shares of Common
Stock at a price per share less than the Current Market Price per share of
Common Stock on the date fixed for the determination of shareholders entitled
to receive such rights, warrants or options, the Settlement Rate in effect at
the opening of business on the day following the date fixed for such
determination shall be increased by dividing such Settlement Rate by a fraction
of which:

               (i)  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

              (ii)  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 increase to become effective immediately after the opening of business on
the day following the date fixed for such determination. For the purposes of
this paragraph (2), the number of shares of Common 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 agrees that it shall not issue
any such rights, warrants or options in respect of shares of Common Stock held
in the treasury of the Company.

         (3)   In case outstanding shares of Common Stock shall be subdivided or
split into a greater number of shares of Common Stock, the 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 each be combined
into a smaller number of shares of Common Stock, the Settlement Rate in effect
at the opening of business on the day following the day upon which such
combination becomes effective shall be proportionately reduced, such increase or
reduction, 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)   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, warrants or options referred to
in paragraph (2) of this Section 5.04(a), any dividend or distribution paid
exclusively in cash and any dividend or distribution referred to in paragraph
(1) of this Section 5.04(a)), the Settlement Rate shall be adjusted so that the
same shall equal the rate determined by dividing the Settlement Rate in effect
immediately prior to the close of business on the date fixed for the
determination of shareholders entitled to receive such distribution by a
fraction of which:

                                      44
<Page>

               (i)  the numerator shall be the Current Market Price per share of
         Common Stock on the date fixed for such determination less the then
         fair market value (as reasonably determined by the Board of Directors,
         whose determination shall be conclusive and the basis for which shall
         be 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

              (ii)  the denominator shall be such Current Market Price per share
         of Common Stock,

such adjustment to become effective immediately prior to the opening of business
on the day following the date fixed for the determination of shareholders
entitled to receive such distribution. In any case in which this paragraph (4)
is applicable, paragraph (2) of this Section 5.04(a) shall not be applicable. In
the event that such dividend or distribution is not so paid or made, the
Settlement Rate shall again be adjusted to be the Settlement Rate which would
then be in effect if such dividend or distribution had not been declared.

         (5)   In case the Company shall, by dividend or otherwise, distribute
to all holders of its Common Stock cash (excluding:

               (i)  any quarterly cash dividend on Common Stock to the extent
         that the aggregate cash dividend per share of Common Stock in any
         fiscal quarter does not exceed $____ per share (as adjusted from time
         to time to reflect the subdivisions or combinations of Common Stock,
         the "DIVIDEND THRESHOLD"), and

              (ii)  any dividend or distribution in connection with the
         liquidation, dissolution or termination of the Company, whether
         voluntary or involuntary),

then, in such case, the Settlement Rate shall be increased so that the same
shall equal the rate determined by dividing the Settlement Rate in effect
immediately prior to the close of business on such record date by a fraction of
which:

               (i)  the numerator shall be the Current Market Price of Common
         Stock on the record date less the amount of cash so distributed (and
         not excluded as provided above) applicable to one share of Common
         Stock; and

              (ii)  the denominator shall be the Current Market Price of Common
         Stock,

such increase to be effective immediately prior to the opening of business on
the day following the record date; PROVIDED, HOWEVER, that in the event the
portion of cash so distributed applicable to one share of Common Stock is equal
to or greater than the Current Market Price per share of Common

                                      45
<Page>

Stock on the record date, in lieu of the foregoing adjustment, adequate
provision shall be made so that each holder of a Security shall have the right
to receive upon settlement of the Securities the amount of cash such Holder
would have received had such Holder settled each Security on the record date.
In the event that such dividend or distribution is not so paid or made, the
Settlement Rate shall again be adjusted to be the Settlement Rate which would
then be in effect if such dividend or distribution had not been declared. If
any adjustment is required to be made as set forth in this Section 5.04(a)(5)
as a result of a distribution that is a quarterly dividend, such adjustment
shall be based upon the amount by which such distribution exceeds the amount of
the Dividend Threshold. If an adjustment is required to be made as set forth in
this Section 5.04(a)(5) above as a result of a distribution that is not a
quarterly dividend, such adjustment shall be based upon the full amount of the
distribution.

                  (6) In case a tender or exchange offer made by the Company or
any subsidiary of the Company for all or any portion of Common Stock shall
expire and such tender or exchange offer (as amended upon the expiration
thereof) shall require the payment to shareholders (based on the acceptance (up
to any maximum specified in the terms of the tender or exchange offer) of
Purchased Shares as herein defined) of (I) an aggregate consideration having a
fair market value (as reasonably determined by the Board of Directors, whose
determination shall be conclusive and the basis for which shall be described in
a Board Resolution) that combined together with the aggregate of the cash plus
the fair market value (as reasonably determined by the Board of Directors,
whose determination shall be conclusive and the basis for which shall be
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 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 this paragraph (6) has been made, and (II) the aggregate amount of any
distributions to all holders of 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 paragraph (6) has been made, exceeds
15% of the product of the Current Market Price per share of 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) on the Expiration
Time, then, and in each such case, immediately prior to the opening of business
on the day after the date of the Expiration Time, the Settlement Rate shall be
adjusted so that the same shall equal the rate determined by dividing the
Settlement Rate immediately prior to the close of business on the date of the
Expiration Time by a fraction:

               (i)  the numerator of which shall be equal to (A) the product of
         (I) the Current Market Price per share of Common Stock on the date of
         the Expiration Time and (II) the number of shares of Common Stock
         outstanding (including any tendered shares) on the Expiration Time
         less (B) the amount of cash plus the fair market value (determined as
         aforesaid) of the aggregate consideration payable to shareholders
         based on the transactions described in clauses (I) and (II) above
         (assuming in the case of clause (I) the acceptance, up to

                                      46
<Page>

         any maximum specified in the terms of the tender or exchange offer, of
         Purchased Shares); and

              (ii)  the denominator of which shall be equal to the product of
         (A) the Current Market Price per share of Common Stock as of the
         Expiration Time and (B) 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)   The reclassification of Common Stock into securities including
securities other than Common Stock (other than any reclassification upon a
Reorganization Event to which Section 5.04(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 shareholders 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)   The "CURRENT MARKET PRICE" per share of Common Stock on any date
of determination means the average of the daily Closing Prices for the five
consecutive Trading Days selected by the Company commencing not more than 30
Trading Days before, and ending not later than, the earlier of such date of
determination and the day before the "ex date" with respect to the issuance or
distribution requiring such computation. 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 Common Stock trades on such exchange or in such
market without the right to receive such issuance or distribution.

         (9)   All adjustments to the Settlement Rate 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 shall be required unless such adjustment would require an
increase or decrease of at least one percent thereof; PROVIDED, HOWEVER, 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

                                      47
<Page>

pursuant to paragraph (1), (2), (3), (4), (5), (6), (7) or (10) of this Section
5.04(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 in Section 5.01 will apply on the Purchase Contract Settlement
Date. Such adjustment shall be made by multiplying the Applicable Market Value
by a fraction of which the numerator shall be the Settlement Rate immediately
after such adjustment pursuant to paragraph (1), (2), (3), (4), (5), (6), (7)
or (10) of this Section 5.04(a) and the denominator shall be the Settlement
Rate immediately prior to such adjustment; PROVIDED, HOWEVER, that if such
adjustment to the Settlement Rate is required to be made pursuant to the
occurrence of any of the events contemplated by paragraph (1), (2), (3), (4),
(5), (6), (7) or (10) of this Section 5.04(a) during the period taken into
consideration for determining the Applicable Market Value, appropriate and
customary adjustments shall be made to the Settlement Rate.

         (10)  The Company may, but shall not be required to, make such
increases in the Settlement Rate, 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 reason.

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

         (1)   In the event of:

               (i)  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 shares of
         Common Stock outstanding immediately prior to the merger or
         consolidation are not exchanged for cash, securities or other property
         of the Company or another corporation);

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

             (iii)  any statutory share exchange of the Company with another
         Person (other than in connection with a merger or acquisition); or

              (iv)  any liquidation, dissolution or termination of the Company
         other than as a result of or after the occurrence of a Termination
         Event, (any such event, a "REORGANIZATION EVENT"),

the Settlement Rate will be adjusted to provide that each Holder of Securities
will receive on the Purchase Contract Settlement Date with respect to each
Purchase Contract forming a part thereof, the kind and amount of securities,
cash and other property receivable upon such Reorganization Event (without any
interest thereon, and without any right to dividends or distribution thereon
which have a record date that is prior to the Purchase Contract Settlement Date)
by a Holder of the number of

                                      48
<Page>

shares of Common Stock issuable on account of each Purchase Contract if the
Purchase Contract Settlement Date had occurred immediately prior to such
Reorganization Event, assuming such Holder of Common Stock 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 such
Holder 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).

         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, dissolution or termination of the
Company, the Company or a liquidating trust created in connection therewith,
shall execute and deliver to the Purchase Contract Agent an agreement
supplemental hereto providing that each Holder of an Outstanding Security shall
have the rights provided by this Section 5.04(b). 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.

         (2)   In the event of a consolidation or merger of the Company with or
into another Person, any merger of another Person into the Company (other than a
merger that does not result in any reclassification, conversion, exchange or
cancellation of outstanding shares of Common Stock) in which 30% or more of the
total consideration paid to the Company's shareholders consists of cash or cash
equivalents, then a Holder of a Security may settle his Purchase Contract for
cash as described in Section 5.02(a)(i) or 5.02(d)(i) hereof, as applicable,
during the one week period beginning on the twenty-third Trading Day following
the closing date of such merger (the "EARLY SETTLEMENT WEEK"), at the applicable
Settlement Rate. For the purposes of this Section, the twenty-third Trading Day
after the closing of the merger or consolidation shall be deemed to be the
Purchase Contract Settlement Date for the purpose of determining the Applicable
Market Value and the deadline for submitting the notice to settle early and the
related cash payment shall be 5:00 p.m. (New York City time) of the last
Business Day of the Early Settlement Week. Notwithstanding the foregoing, no
early settlement will be permitted under this Section 5.04(b)(2) unless, at the
time such early settlement is effected, there is an effective Registration
Statement with respect to the shares of Common Stock to be issued and delivered
in connection with such early settlement, if such a Registration Statement is
required (in the

                                      49
<Page>

view of counsel, which need not be in the form of a written opinion, for either
the Company or the Purchase Contract Agent) under the Securities Act. If such a
Registration Statement is so required, the Company covenants and agrees to use
its best efforts to (A) have in effect a Registration Statement covering the
shares of Common Stock to be delivered in respect of the Purchase Contracts
being settled and (B) provide a Prospectus in connection therewith, in each
case in a form that the Purchase Contract Agent may use in connection with such
early settlement.

         (c)   All calculations and determinations pursuant to this Section 5.04
shall be made by the Company or its agent and the Purchase Contract Agent shall
have no responsibility with respect thereto.

         SECTION 5.05.  NOTICE OF ADJUSTMENTS AND CERTAIN OTHER EVENTS.

         (a)   Whenever the Settlement Rate is adjusted as herein provided, the
         Company shall:

               (i)  forthwith compute the adjusted Settlement Rate in accordance
         with Section 5.04 and prepare and transmit to the Purchase Contract
         Agent an Officers' Certificate setting forth the Settlement Rate, the
         method of calculation thereof in reasonable detail, and the facts
         requiring such adjustment and upon which such adjustment is based; and

              (ii)  within 10 Business Days following the occurrence of an event
         that requires an adjustment to the Settlement Rate pursuant to Section
         5.04 (or if the Company is not aware of such occurrence, as soon as
         practicable after becoming so aware), provide a written notice to the
         Holders of the Securities of the occurrence of such event and a
         statement in reasonable detail setting forth the method by which the
         adjustment to the Settlement Rate was determined and setting forth the
         adjusted Settlement Rate.

         (b)   The Purchase Contract Agent shall not at any time be under any
duty or responsibility to any Holder of Securities to determine whether any
facts exist which may require any adjustment of the Settlement Rate, 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 Purchase Contract
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 the time be issued or delivered with respect to any Purchase
Contract; and the Purchase Contract Agent makes no representation with respect
thereto. The Purchase Contract 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 5.06.  TERMINATION EVENT; NOTICE.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders

                                      50
<Page>

thereunder, including, without limitation, the rights of the Holders to receive
and the obligation of the Company to pay any Purchase Contract Payments
(including any deferred or accrued and unpaid Purchase Contract Payments), if
the Company shall have such obligation, 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
Purchase Contract Agent or the Company, if, prior to or on the Purchase
Contract Settlement Date, a Termination Event shall have occurred.

         Upon and after the occurrence of a Termination Event, the Securities
shall thereafter represent the right to receive the Preferred Securities, the
[Subordinated] Notes, the Treasury Securities or the appropriate Applicable
Ownership Interest of the Treasury Portfolio, as the case may be, forming part
of such Securities, in accordance with the provisions of Section 5.04 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 Purchase Contract Agent, the Collateral Agent and the Holders, at
their addresses as they appear in the Security Register.

         SECTION 5.07.  EARLY SETTLEMENT.

         (a)   Subject to and upon compliance with the provisions of this
Section 5.07, at the option of the Holder thereof, Purchase Contracts
underlying Securities may be settled early ("EARLY SETTLEMENT") on or prior to
5:00 p.m. (New York City time) on the seventh Business Day immediately
preceding the Purchase Contract Settlement Date. Holders of Treasury Stock
Purchase Units may only settle the related Purchase Contracts in integral
multiples of 40 Purchase Contracts. In order to exercise the right to effect
Early Settlement with respect to any Purchase Contracts, the Holder of the
Certificate evidencing Securities shall deliver to the Purchase Contract Agent
at the Corporate Trust Office an "Election to Settle Early" form (on the
reverse side of the Certificate) and any other documents requested by the
Purchase Contract Agent and accompanied by payment (payable to the Company in
immediately available funds) in an amount (the "EARLY SETTLEMENT AMOUNT") equal
to the product of (i) (A) the Stated Amount times (B) the number of Purchase
Contracts with respect to which the Holder has elected to effect Early
Settlement, plus (ii) 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 Purchase Contract Payments payable on such Payment Date
with respect to such Purchase Contracts.

         Except as provided in the immediately preceding sentence and subject to
Section 5.11(c), no payment shall be made upon Early Settlement of any Purchase
Contract on account of any Purchase Contract Payments accrued on such Purchase
Contract or on account of dividends payable on the Common Stock issued upon such
Early Settlement, the record date for which payment occurs prior to the Early
Settlement Date. If the foregoing requirements are first satisfied with respect
to Purchase Contracts underlying any Securities prior to or at 5:00 p.m. (New
York City time) on a Business Day, such day shall be the "EARLY SETTLEMENT DATE"
with respect to such Securities and if such requirements are first satisfied
after 5:00 p.m. (New York City time) on a Business Day or on a day

                                      51
<Page>

that is not a Business Day, the "EARLY SETTLEMENT DATE" with respect to such
Securities shall be the next succeeding Business Day (so long as such next
succeeding Business Day is not later than the seventh Business Day immediately
preceding the Purchase Contract Settlement Date).

         (b)   No Early Settlement will be permitted under this Section 5.07
unless, at the time of delivery of the Election to Settle Early form or time the
Early Settlement is effected, there is an effective Registration Statement with
respect to the shares of Common Stock to be issued and delivered in connection
with such Early Settlement, if such a Registration Statement is required (in
the view of counsel, which need not be in the form of a written opinion, for
either the Company or the Purchase Contract Agent) under the Securities Act. If
such a Registration Statement is so required, the Company covenants and agrees
to use its best efforts to (A) have in effect a Registration Statement covering
the shares of Common Stock to be delivered in respect of the Purchase Contracts
being settled and (B) provide a Prospectus in connection therewith, in each case
in a form that the Purchase Contract Agent may use in connection with such Early
Settlement.

         (c)   Upon Early Settlement of Purchase Contracts by a Holder of the
related Securities, the Company shall issue, and the Holder shall be entitled to
receive _______ share of Common Stock on account of each Purchase Contract as to
which Early Settlement is effected (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.

         (d)   Not 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, together with payment in
         lieu of any fraction of a share, as provided in Section 5.09; and

              (ii)  the related Preferred Securities, [Subordinated] Notes or
         the appropriate Applicable Ownership Interest (as specified in clause
         (A) of the definition of such term) of the Treasury Portfolio, in the
         case of Stock Purchase Units, or the related Treasury Securities, in
         the case of Treasury Stock Purchase Units, to be released from the
         Pledge by the Collateral Agent and transferred, in each case, to the
         Purchase Contract Agent for delivery to the Holder thereof or its
         designee.

         (e)   Upon Early Settlement of any Purchase Contracts, and subject to
receipt of shares of Common Stock from the Company and the Preferred Securities,
[Subordinated] Notes, the appropriate Applicable Ownership Interest as specified
in clause (A) of the definition of such term) of the Treasury Portfolio, or
Treasury Securities, as the case may be, from the Securities Intermediary, as
applicable, the Purchase Contract Agent shall, in accordance with the
instructions provided by the Holder thereof on the Election to Settle Early form
(on the reverse of the Certificate evidencing the

                                      52
<Page>

related Securities):

               (i)  transfer to the Holder the Preferred Securities,
         [Subordinated] Notes, the appropriate Applicable Ownership Interest (as
         specified in clause (A) of the definition of such term) of the
         Treasury Portfolio or Treasury Securities, as the case may be, forming
         a part of such Securities;

              (ii)  deliver to the Holder a certificate or certificates 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 5.09; and

             (iii)  if so required under the Securities Act, deliver a
         Prospectus for the shares of Common Stock issuable upon such Early
         Settlement as contemplated by Section 5.07(b).

         (f)   In the event that Early Settlement is effected with respect to
Purchase Contracts underlying less than all the Securities evidenced by a
Certificate, upon such Early Settlement the Company shall execute and the
Purchase Contract Agent shall authenticate, countersign and deliver to the
Holder thereof, at the expense of the Company, a Certificate evidencing the
Securities as to which Early Settlement was not effected.

         (g)   A Holder of a Security who effects Early Settlement may elect to
have the Preferred Securities or [Subordinated] Notes, as the case may be, no
longer a part of a Stock Purchase Unit remarketed. A Holder making such an
election must notify the Property Trustee or the Indenture Trustee, as the case
may be, prior to 11:00 a.m. (New York City time) on the fifth Business Day
immediately preceding the Purchase Contract Settlement Date, of the aggregate
number of Preferred Securities or [Subordinated] Notes that are not part of
Stock Purchase Units to be remarketed. Any such notice will be irrevocable and
may not be conditioned upon the level at which the Reset Rate is established in
the Remarketing. Concurrently, the Property Trustee or the Indenture Trustee, as
the case may be, shall cause such Preferred Securities or [Subordinated] Notes,
as the case may be, to be presented to the Remarketing Agent for Remarketing.

         SECTION 5.08.  INTENTIONALLY OMITTED.

         SECTION 5.09.  NO FRACTIONAL SHARES.

         No fractional shares or scrip representing fractional shares of Common
Stock shall be issued or delivered upon settlement on the Purchase Contract
Settlement Date or upon 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

                                      53
<Page>

Stock which would otherwise be deliverable upon settlement of any Purchase
Contracts on the Purchase Contract Settlement Date or upon Early Settlement,
the Company, through the Purchase Contract Agent, shall make a cash payment in
respect of such fractional interest in an amount equal to the value of such
fractional shares times the Applicable Market Value. The Company shall provide
the Purchase Contract Agent from time to time with sufficient funds to permit
the Purchase Contract Agent to make all cash payments required by this Section
5.09 in a timely manner.

         SECTION 5.10.  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, HOWEVER, 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 a Security 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 Securities evidenced
thereby, other than in the name of the Purchase Contract Agent, as custodian
for such Holder, and the Company shall not be required to issue or deliver such
share certificates or Certificates unless or 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 5.11.  PURCHASE CONTRACT PAYMENTS.

         (a)   Subject to Section 5.12, the Company shall pay, on each Payment
Date, the Purchase Contract Payments payable in respect of each Purchase
Contract to the Person in whose name a Certificate is registered at the close of
business on the Record Date next preceding such Payment Date. The Purchase
Contract Payments will be payable at the office of the Purchase Contract Agent
in New York City maintained for that purpose or, at the option of the Holder, by
check mailed to the address of the Person entitled thereto at such Person's
address as it appears on the Security Register. If any date on which Purchase
Contract Payments are to be made is not a Business Day, then payment of the
Purchase Contract Payments payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest in respect of
any such delay), except that, if such Business Day is in the next succeeding
calendar year, such payment will be made on the immediately preceding Business
Day. Purchase Contract Payments payable for any period will be computed (i) for
any full quarterly period on the basis of a 360-day year of twelve 30-day months
and (ii) for any period shorter than a full quarterly period, on the basis of a
30-day month and, for periods of less than a month, on the basis of the actual
number of days elapsed per 30-day month.

         (b)   Upon the occurrence of a Termination Event, the Company's
obligation to pay future Purchase Contract Payments (including any accrued or
deferred Purchase Contract Payments) shall cease.

                                      54
<Page>

         (c)   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 reestablishment of Stock Purchase Units) any
other Certificate shall carry the right to accrued or deferred and unpaid
Purchase Contract Payments and the right to accrue Purchase Contract Payments,
which rights were carried by the Purchase Contracts underlying such other
Certificates.

         (d)   Subject to Section 5.07, in the case of any Security with respect
to which Early Settlement of the underlying Purchase Contract is effected on an
Early Settlement Date that is after any Record Date and prior to or on the next
succeeding Payment Date, Purchase Contract Payments otherwise payable on such
Payment Date shall be payable on such Payment Date notwithstanding such Early
Settlement, and such Purchase Contract Payments shall be paid to the Person in
whose name the Certificate evidencing such Security 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 Security with respect to
which Early Settlement of the underlying Purchase Contract is effected on an
Early Settlement Date, Purchase Contract Payments that would otherwise be
payable after the Early Settlement Date with respect to such Purchase Contract
shall not be payable.

         SECTION 5.12.  DEFERRAL OF PURCHASE CONTRACT PAYMENTS.

         (a)   The Company has the right to defer payment of all or part of the
Purchase Contract Payments in respect of each Purchase Contract until no later
than the Purchase Contract Settlement Date, but only if the Company shall give
the Holders and the Purchase Contract Agent written notice of its election to
defer such payment (specifying the amount to be deferred) at least ten Business
Days prior to the earlier of (i) the next succeeding Payment Date or (ii) the
date the Company is required to give notice of the Record Date or Payment Date
with respect to payment of such Purchase Contract Payments to the NYSE or other
applicable self-regulatory organization or to Holders of the Securities, but in
any event not less than one Business Day prior to such Record Date. If the
Company so elects to defer Purchase Contract Payments, the Company shall pay
additional Purchase Contract Payments on such deferred installments of Purchase
Contract Payments at a rate equal to ___% per annum, compounding quarterly,
until such deferred installments are paid in full. Deferred Purchase Contract
Payments shall be due on the Payment Date except to the extent that payment is
deferred pursuant to this Section. Except as otherwise provided in Section
5.11(d), in the case of any Security with respect to which Early Settlement of
the underlying Purchase Contract is effected on an Early Settlement Date, the
Holder will have no right to receive any accrued or deferred Purchase Contract
Payments.

         (b)   In the event the Company elects to defer the payment of Purchase
Contract Payments on the Purchase Contracts until the Purchase Contract
Settlement Date, each Holder will receive on the Purchase Contract Settlement
Date the aggregate amount of accrued and unpaid Purchase Contract Payments. The
Company shall pay such amounts on the Purchase Contract Settlement Date in the
manner described in Section 5.02(e).

                                      55

         (c)   In the event the Company exercises its option to defer the
payment of Purchase Contract Payments, then, until all deferred Purchase
Contract Payments have been paid, the Company shall not (a) make any payment of
principal, interest or premium, if any, on or repay, repurchase or redeem any
debt securities that rank junior to the [Subordinated] Notes in the right of
payment issued by the Company, or (b) make any guarantee payments with respect
to any guarantee by the Company of any securities of any of its subsidiaries if
such guarantee ranks junior to the [Subordinated] Notes in the right of
payment, (c) declare or pay any dividends or distributions on any of the
Company's capital stock or (d) redeem, purchase, acquire or make a liquidation
payment with respect to, any of the Company's capital stock. Notwithstanding
the foregoing, the Company may (1) purchase or acquire its capital stock in
connection with the satisfaction by it of its obligations under any employee
benefit plans or pursuant to any contract or security outstanding on the first
day of any such event requiring it to purchase its capital stock; (2)
reclassify its capital stock or exchange or convert one class or series of its
capital stock for another class or series of its capital stock; (3) purchase
fractional interests in shares of its capital stock pursuant to the conversion
or exchange provisions of such capital stock or the security being converted or
exchanged; (4) declare dividends or distributions in its capital stock; (5)
redeem or repurchase any rights pursuant to a rights agreement; and (6) make
payments under the Guarantee related to the Preferred Securities.

                                    REMEDIES

         SECTION 6.01. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PURCHASE
CONTRACT PAYMENTS AND TO PURCHASE SHARES OF COMMON STOCK.

         Each Holder of a Security shall have the right, which is absolute and
unconditional, (i) subject to the right of the Company to defer such payments in
accordance with Section 5.12, to receive each Purchase Contract Payment with
respect to the Purchase Contract comprising part of such Security on the
respective Payment Date for such Security and (ii) to purchase shares of Common
Stock pursuant to such Purchase Contract and, in each such case, to institute
suit for the enforcement of any such right to receive Purchase Contract Payments
and the right to purchase shares of Common Stock, and such rights shall not be
impaired without the consent of such Holder.

         SECTION 6.02.  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 6.03.  RIGHTS AND REMEDIES CUMULATIVE.

         Except as otherwise provided with respect to the replacement or payment
of mutilated, destroyed, lost or stolen Certificates in the last paragraph of
Section 3.10, 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 6.04.  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 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 6.05.  UNDERTAKING FOR COSTS.

         All parties to this Agreement agree, and each Holder of a Security, by
its acceptance of such Security 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 Purchase Contract Agent
for any action taken, suffered or omitted by it as Purchase Contract 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 costs 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 Purchase Contract Agent,
to any suit instituted by any Holder, or group of Holders, holding in the
aggregate more than 10% of the Outstanding Securities, or to any suit instituted
by any Holder for the enforcement of distributions on any Preferred Securities
or interest on any [Subordinated] Notes or Purchase Contract Payments on or
after the respective Payment Date therefor in respect of any Security held by
such Holder, or for enforcement of the right to purchase shares of Common Stock
under the Purchase Contracts constituting part of any Security held by such
Holder.

         SECTION 6.06.  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 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
and covenants that it will not

                                      57
<Page>

hinder, delay or impede the execution of any power herein granted to the
Purchase Contract Agent or the Holders, but will suffer and permit the
execution of every such power as though no such law had been enacted.

successor Purchase Contract Agent.

          (c) The Purchase Contract Agent may be removed at any time by Act of
the Holders of a majority in number of the Outstanding Securities delivered to

             (1) the Purchase Contract Agent fails to comply with Section 310(b)
         of the TIA, as if the Purchase Contract Agent were an indenture trustee
         under an indenture qualified under the TIA, after written request
         therefor by the Company or by any Holder who has been a bona fide
         Holder of a Security for at least six months;

             (2) the Purchase Contract Agent shall cease to be eligible under

         Contract Agent or of its property shall be appointed or any public
         officer shall take charge or control of the Purchase Contract Agent or
         of its property or affairs for the purpose of rehabilitation,
         conservation or liquidation,

then, in any such case, (i) the Company by a Board Resolution may remove the
Purchase Contract Agent, or (ii) any Holder who has been a bona fide Holder of a
Security 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 Purchase Contract Agent and the appointment of a successor Purchase
Contract Agent.

          (e) If the Purchase Contract Agent shall resign, be removed or become
incapable of acting, or if a vacancy shall occur in the office of Purchase
Contract Agent for any cause, the Company, by a Board Resolution, shall promptly
appoint a successor Purchase Contract Agent and shall comply with the applicable
requirements of Section 7.10. If no successor Purchase Contract 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 a Security for at
least six months, on behalf of itself and all others similarly situated, or the
Purchase Contract Agent may petition at the expense of the Company, any court of
competent jurisdiction for the appointment of a successor Purchase Contract
Agent.

          (f) The Company shall give, or shall cause such successor Purchase
Contract Agent to give, notice of each resignation and each removal of the
Purchase Contract Agent and each appointment of a successor Purchase Contract
Agent by mailing written notice of such event by first-class mail, postage

         SECTION 7.10. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

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

          (b) Upon request of any such successor Purchase Contract Agent, the
Company shall execute any and all instruments for more fully and certainly
vesting in and confirming to such successor Purchase Contract Agent all such
rights, powers and agencies referred to in paragraph 7.10(a) of this Section.

          (c) No successor Purchase Contract Agent shall accept its appointment

shall be qualified and eligible under this Article.

         SECTION 7.11. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO
BUSINESS.

         Any corporation into which the Purchase Contract 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 Purchase Contract
Agent shall be a party, or any corporation succeeding to all or substantially
all the corporate trust business of the Purchase Contract Agent, shall be the
successor of the Purchase Contract Agent hereunder, PROVIDED that such
corporation shall be otherwise qualified and eligible under this Article, with
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 Purchase Contract
Agent then in office,

                                      64

<Page>

any successor by merger, conversion or consolidation to such Purchase Contract
Agent may adopt such authentication and execution and deliver the Certificates
so authenticated and executed with the same effect as if such successor
Purchase Contract Agent had itself authenticated and executed such Securities.

         SECTION 7.12. PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

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

          (b) If three or more Holders (herein referred to as "applicants")
apply in writing to the Purchase Contract Agent, and furnish to the Purchase
Contract Agent reasonable proof that each such applicant has owned a Security
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
Securities and is accompanied by a copy of the form of proxy or other
communication which such applicants propose to transmit, then the Purchase
Contract 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 Purchase Contract Agent of the materials to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of such mailing.

         SECTION 7.13. NO OBLIGATIONS OF PURCHASE CONTRACT AGENT.

         Except to the extent otherwise expressly provided in this Agreement,
the Purchase Contract Agent assumes no obligations 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 Security thereunder.
The Company agrees, and each Holder of a Certificate, by his or her acceptance
thereof, shall be deemed to have agreed, that the Purchase Contract 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 Purchase Contract Agent shall
have no obligation to perform such Purchase Contracts on behalf of the Holders,
except to the extent expressly provided in Article Five hereof. Anything
contained in this Agreement to the contrary notwithstanding, in no event shall
the Purchase Contract Agent or its 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 Purchase
Contract Agent, incurred without any act or deed that is found to be

         SECTION 9.01. COVENANT NOT TO CONSOLIDATE, MERGE, CONVEY, TRANSFER OR
LEASE PROPERTY EXCEPT UNDER CERTAIN CONDITIONS.

         The Company covenants that it will not consolidate with or merge into
any other corporation or convey, transfer or lease all or substantially all of
its properties and assets to any Person, unless:

              (i) the corporation formed by such consolidation or into which the
         Company is merged or the Person which acquires by conveyance or
         transfer, or which leases, all or substantially all of the Company's
         properties and assets shall be a corporation organized and existing
         under the laws of the United States of America or a State thereof or
         the District of Columbia and such corporation shall expressly assume
         all the obligations of the Company under the Purchase Contracts, this
         Agreement and the Pledge Agreement by one or more supplemental
         agreements in form reasonably satisfactory to the Purchase Contract
         Agent and the Collateral Agent, executed and delivered to the Purchase
         Contract Agent and the Collateral Agent by such corporation; and

              (ii) the Company or such successor corporation, as the case may
         be, shall not, immediately after such consolidation, merger,
         conveyance, transfer or lease, be in default in the performance of any
         covenant or condition hereunder, under any of the Securities or under
         the Pledge Agreement.

         In case of any such merger, consolidation, share exchange, sale,
assignment, transfer, lease or conveyance and upon any such assumption by a
successor corporation in accordance with Section 9.01, such successor
corporation shall succeed to and be substituted for the Company with the same
effect as if it had been named herein as the Company. Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of Cinergy Corp., any or all of the Certificates evidencing Securities
issuable hereunder which theretofore shall not have been signed by the Company
and delivered to the Purchase Contract Agent; and, upon the order of such
successor corporation, instead of the Company, and subject to all the terms,
conditions and limitations in this Agreement prescribed, the Purchase Contract
Agent shall authenticate and execute on behalf of the Holders and deliver any
Certificates which previously shall have been signed and delivered by the
officers of the Company to the Purchase Contract Agent for authentication and
execution, and any

                                      69

<Page>

Certificate evidencing Securities which such successor corporation thereafter
shall cause to be signed and delivered to the Purchase Contract Agent for that
purpose. All the Certificates issued shall in all respects have the same legal
rank and benefit under this Agreement as the Certificates theretofore or
thereafter issued in accordance with the terms of this Agreement as though all
of such Certificates had been issued at the date of the execution hereof.

         In case of any such merger, consolidation, share exchange, sale,
assignment, transfer, lease or conveyance such change in phraseology and form
(but not in substance) may be made in the Certificates evidencing Securities
thereafter to be issued as may be appropriate.

         SECTION 9.03. OFFICERS' CERTIFICATE AND OPINION OF COUNSEL GIVEN TO
PURCHASE CONTRACT AGENT.

         The Purchase Contract Agent, subject to Sections 7.01 and 7.03, shall

provisions of this Article and that all conditions precedent to the consummation

financial officer or principal accounting officer of the Company), stating
whether or not to the knowledge of the signers 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 they may have knowledge.

         SECTION 10.06. ERISA.

         Each Holder from time to time of the Securities that is a Plan hereby
represents that its

                                      71

              (FORM OF REVERSE OF STOCK PURCHASE UNITS CERTIFICATE)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of _____________, 2001 (as may be supplemented
from time to time, the "PURCHASE CONTRACT AGREEMENT"), between the Company and
[                            ], as Purchase Contract Agent (including its
successors hereunder, the "PURCHASE CONTRACT 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 Purchase Contract Agent, the Company, and the
Holders and of the terms upon which the Stock Purchase Units Certificates are,
and are to be, executed and delivered.

         Unless a Cash Settlement or an Early Settlement has occurred, each
Purchase Contract evidenced hereby obligates the Holder of this Stock Purchase
Units Certificate to purchase, and the Company to sell, on the Purchase Contract
Settlement Date at a price equal to the Stated Amount (the "PURCHASE PRICE"), a
number of shares of Common Stock equal to the Settlement Rate, unless, prior to
or on the Purchase Contract Settlement Date, there shall have occurred a
Termination Event with respect to the Security of which such Purchase Contract
is a part or an Early Settlement shall have occurred. The "SETTLEMENT RATE" is
equal to:

              (1) if the Applicable Market Value (as defined below) is greater
         than or equal to $______ (the "THRESHOLD APPRECIATION PRICE"), _____
         shares of Common Stock per Purchase Contract;

              (2) if the Applicable Market Value is less than the Threshold
         Appreciation Price but greater than $______ (the "REFERENCE PRICE"),
         the number of shares of Common Stock per Purchase Contract having a
         value, based on the Applicable Market Value, equal to $25; and

              (3) if the Applicable Market Value is less than or equal to the
         Reference Price, _____ share 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 Section 5.09 of the Purchase Contract
Agreement.

         Each Purchase Contract evidenced hereby, which is settled either
through Early Settlement or Cash Settlement, shall obligate the Holder of the
related Stock Purchase Unit to purchase at the Purchase Price, and the Company
to sell, a number of shares of Common Stock equal to the Early Settlement Rate
or Settlement Rate, as applicable.

                                     A-6
<Page>

         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 Purchase Contract Settlement
Date.

         The "CLOSING PRICE" per share of Common Stock on any date of
determination means:

              (1) the closing sale price as of the close of the principal
         trading session (or, if no closing price is reported, the last reported
         sale price) per share on the New York Stock Exchange, Inc. (the "NYSE")
         on such date;

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

              (3) if Common Stock is not so listed on a United States national
         or regional securities exchange, the closing sale price per share as
         reported by The Nasdaq National Market;

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

              (5) if such bid price is not available, the average of the
         mid-point of the last bid and ask prices of Common Stock on such date
         from at least three nationally recognized independent investment
         banking firms retained for this purpose by the Company.

         A "TRADING DAY" means a day on which Common Stock (1) 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 (2) 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 Common
Stock.

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Stock Purchase Units Certificate may pay the Purchase Price for
the shares of Common Stock purchased pursuant to each Purchase Contract
evidenced hereby by effecting a Cash Settlement or an Early Settlement or from
the proceeds of the Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio or a Remarketing of the
related Pledged Preferred Securities. A Holder of Stock Purchase Units who does
not effect, on or prior to 11:00 a.m. (New York City time) on the fifth Business
Day immediately preceding the Purchase Contract Settlement Date (or in the event
a Tax Event Redemption has occurred, the Business Day prior to the Purchase
Contract Settlement Date), an effective Cash Settlement, or who does not effect
on or prior to 5:00 p.m. (New York City time) on the seventh Business Day prior
to the Purchase Contract Settlement Date an effective Early Settlement, shall
pay the Purchase Price for the shares of Common Stock to be

                                     A-7

<Page>

delivered under the related Purchase Contract from the proceeds of the sale of
the related Pledged Preferred Securities held by the Collateral Agent. Such
sale will be made by the Remarketing Agent pursuant to the terms of the
Remarketing Agreement on the third Business Day prior to the Purchase Contract
Settlement Date. If, as provided in the Purchase Contract Agreement, upon the
occurrence of a Failed Remarketing, the Collateral Agent, for the benefit of
the Company, exercises its rights as a secured creditor with respect to the
Pledged Preferred Securities related to this Stock Purchase Units certificate,
any accrued and unpaid distributions on such Pledged Preferred Securities will
become payable by the Company to the holder of this Stock Purchase Units
Certificate in the manner provided for in the Purchase Contract Agreement.

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

         Each Purchase Contract evidenced hereby and all obligations and rights
of the Company and the Holder thereunder shall terminate if a Termination Event
shall occur. Upon the occurrence of a Termination Event, the Company shall give
written notice to the Purchase Contract Agent and to the Holders, at their
addresses as they appear in the Security Register. Upon and after the occurrence
of a Termination Event, the Collateral Agent shall release the Pledged Preferred
Security or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio forming a
part of each Stock Purchase Unit from the Pledge. A Stock Purchase Unit shall
thereafter represent the right to receive the Preferred Security or the
appropriate Applicable Ownership Interest of the Treasury Portfolio forming a
part of such Stock Purchase Unit in accordance with the terms of the Purchase
Contract Agreement and the Pledge Agreement.

         Under the terms of the Pledge Agreement, the Purchase Contract Agent
will be entitled to exercise the voting and any other consensual rights
pertaining to the Pledged Preferred Securities. Upon receipt of notice of any
meeting at which holders of Preferred Securities are entitled to vote or upon
the solicitation of consents, waivers or proxies of holders of Preferred
Securities, the Purchase Contract Agent shall, as soon as practicable
thereafter, mail to the Stock Purchase Units Holders a notice:

              (1) containing such information as is contained in the notice or
         solicitation;

              (2) stating that each Stock Purchase Unit Holder on the record
         date set by the Purchase Contract Agent therefor (which, to the extent
         possible, shall be the same date as the record date for determining the
         holders of Preferred Securities entitled to vote) shall be entitled to
         instruct the Purchase Contract Agent as to the exercise of the voting
         rights pertaining to the Preferred Securities constituting a part of
         such Holder's Stock Purchase Unit; and

                                     A-8

<Page>

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

Upon the written request of the Stock Purchase Unit Holders on such record date,
the Purchase Contract 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 Preferred Securities as to which any particular
voting instructions are received. In the absence of specific instructions from
the Holder of a Stock Purchase Unit, the Purchase Contract Agent shall abstain
from voting the Preferred Security evidenced by such Stock Purchase Unit.

         Upon the dissolution and liquidation of the Trust, an aggregate
principal amount of the [Subordinated] Notes constituting the assets of the
Trust and underlying the Preferred Securities equal to the aggregate liquidation
amount of the Pledged Preferred Securities shall be delivered to the Securities
Intermediary in exchange for the Pledged Preferred Securities. Thereafter, the
[Subordinated] Notes shall be held by the Securities Intermediary to secure the
obligations of each Holder of Stock Purchase Units to purchase shares of Common
Stock under the Purchase Contracts constituting a part of such Stock Purchase
Units.

         Notwithstanding the foregoing, in the event of a dissolution and
liquidation of the Trust, if a Liquidation Distribution is to be distributed in
lieu of the [Subordinated] Notes as provided for in the Declaration, an amount
equal to the Liquidation Distribution shall be deposited in the Collateral
Account in exchange for the Pledged Preferred Securities. Thereafter, pursuant
to the terms of the Pledge Agreement, the Collateral Agent shall cause the
Securities Intermediary to apply an amount equal to the Redemption Amount of
such Liquidation Distribution to purchase on behalf of the Holders of Stock
Purchase Units the Treasury Portfolio and promptly remit the remaining portion
of such Liquidation Distribution to the Purchase Contract Agent for payment to
the Holders of such Stock Purchase Units. The Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio will be substituted as Collateral for the Pledged Preferred Securities
and will be held by the Collateral Agent in accordance with the terms of the
Pledge Agreement to secure the obligation of each Holder of a Stock Purchase
Unit to purchase the Common Stock of the Company under the Purchase Contract
constituting a part of such Stock Purchase Unit.

         Following the dissolution and liquidation of the Trust, the Holders and
the Collateral Agent shall have such security interests, rights and obligations
with respect to the [Subordinated] Notes or the Applicable Ownership Interest
(as specified in clause (A) of the definition of such term) of the Treasury
Portfolio, as the case may be, as the Holders and the Collateral Agent had in
respect of the Pledged Preferred Securities, any reference herein to the
Preferred Securities shall be deemed to be a reference to the [Subordinated]
Notes or the Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be, and any
reference herein to the liquidation amount of the Preferred Securities shall be
deemed to be a reference to the principal amount of the [Subordinated] Notes or
the Applicable Ownership Interest (as specified in clause (A) of the definition
of such term) of the Treasury Portfolio, as the case may be.

                                     A-9

<Page>

         Upon the occurrence of a Tax Event Redemption prior to the Purchase
Contract Settlement Date, an amount equal to the Redemption Amount plus any
accumulated and unpaid distributions payable on the Tax Event Redemption Date
with respect to the Applicable Principal Amount shall be deposited in the
Collateral Account in exchange for the Pledged Preferred Securities. Thereafter,
pursuant to the terms of the Pledge Agreement, the Collateral Agent shall cause
the Securities Intermediary to apply an amount equal to the Redemption Amount of
such funds to purchase on behalf of the Holders of Stock Purchase Units, the
Treasury Portfolio and promptly (a) transfer the Applicable Ownership Interest
(as specified in clause (A) of the definition of such term) of the Treasury
Portfolio to the Collateral Account to secure the obligations of each Holder of
Stock Purchase Units to purchase shares of Common Stock under the Purchase
Contracts constituting a part of such Stock Purchase Units, (b) transfer the
Applicable Ownership Interest (as specified in clause (B) of the definition of
such term) of the Treasury Portfolio to the Purchase Contract Agent for the
benefit of the Holders of such Stock Purchase Units and (C) remit the remaining
portion of such funds to the Purchase Contract Agent for payment to the Holders
of such Stock Purchase Units.

         Following the occurrence of a Tax Event Redemption prior to the
Purchase Contract Settlement Date, the Holders of Stock Purchase Units and the
Collateral Agent shall have such security interest rights and obligations with
respect to the Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio as the Holder of Stock
Purchase Units and the Collateral Agent had in respect of the Preferred
Securities or [Subordinated] Notes, as the case may be, subject to the Pledge
thereof as provided in the Pledge Agreement and any reference herein to the
Preferred Securities shall be deemed to be a reference to such Treasury
Portfolio.

         The Stock Purchase Certificates are issuable only in registered form
and only in denominations of a single Stock Purchase Unit and any integral
multiple thereof. The transfer of any Stock Purchase Units Certificate will be
registered and Stock Purchase Units Certificates may be exchanged as provided in
the Purchase Contract Agreement. The Security 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 Purchase Contract Agent may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith. A Holder who
elects to substitute a Treasury Security for Preferred Securities, thereby
creating Treasury Stock Purchase 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 Stock
Purchase Unit remains in effect, such Stock Purchase Unit shall not be separable
into its constituent parts, and the rights and obligations of the Holder of such
Stock Purchase Unit in respect of the Preferred Securities and Purchase Contract
constituting such Stock Purchase Unit may be transferred and exchanged only as a
Stock Purchase Unit.

         The Holder of Stock Purchase Units may substitute for the Pledged
Preferred Securities securing such Holder's obligations under the related
Purchase Contracts Treasury Securities in an

                                    A-10

<Page>

aggregate principal amount equal to the aggregate liquidation amount of the
Pledged Preferred Securities in accordance with the terms of the Purchase
Contract Agreement and the Pledge Agreement. From and after such Collateral
Substitution, each Security for which such Pledged Treasury Securities secures
the Holder's obligation under the Purchase Contract shall be referred to as a
"TREASURY STOCK PURCHASE UNIT". A Holder may make such Collateral Substitution
only in integral multiples of 40 Stock Purchase Units for 40 Treasury Stock
Purchase Units.

         A Holder of Treasury Stock Purchase Units may recreate Stock Purchase
Units by delivering to the Securities Intermediary Preferred Securities with an
aggregate liquidation amount equal to the aggregate principal amount at maturity
of the Pledged Treasury Securities in exchange for the release of such Pledged
Treasury Securities in accordance with the terms of the Purchase Contract
Agreement and the Pledge Agreement. A Holder may recreate Stock Purchase Units
only in integral multiples of 40 Treasury Stock Purchase Units for 40 Stock
Purchase Units.

         If a Tax Event Redemption has occurred, a Stock Purchase Unit Holder
may not create Treasury Stock Purchase Units, and a Treasury Stock Purchase Unit
Holder may not recreate a Stock Purchase Unit.

         The Company shall pay, on each Payment Date, the Purchase Contract
Payments payable in respect of each Purchase Contract to the Person in whose
name the Stock Purchase Units Certificate evidencing such Purchase Contract is
registered at the close of business on the Record Date for such Payment Date.
Purchase Contract Payments will be payable at the office of the Purchase
Contract Agent in New York City or, at the option of the Holder, by check mailed
to the address of the Person entitled thereto at such address as it appears on
the Security Register.

         The Company has the right to defer payment of all or part of the
Purchase Contract Payments in respect of each Purchase Contract until no later
than the Purchase Contract Settlement Date. If the Company so elects to defer
Purchase Contract Payments, the Company shall pay additional Purchase Contract
Payments on such deferred installments of Purchase Contract Payments at a rate
equal to ___% per annum, compounding quarterly, until such deferred installments
are paid. In the event that the Company elects to defer the payment of Purchase
Contract Payments on the Purchase Contracts until the Purchase Contract
Settlement Date, each Holder will receive on the Purchase Contract Settlement
Date the aggregate amount of accrued and unpaid Purchase Contract Payments.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive and the obligation of the Company to pay any Purchase
Contract Payments, shall immediately and automatically terminate, without the
necessity of any notice or action by any Holder, the Purchase Contract Agent or
the Company, if, on or prior to the Purchase Contract Settlement 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 Purchase Contract Agent, the

                                    A-11

<Page>

Collateral Agent and the Holders, at their addresses as they appear in the
Security Register. Upon and after the occurrence of a Termination Event, the
Collateral Agent shall release the Preferred Securities or the appropriate
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the Treasury Portfolio, as the case may be, from the Pledge in
accordance with the provisions of the Pledge Agreement.

         Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
underlying Securities may be settled early ("EARLY SETTLEMENT") as provided in
the Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Stock
Purchase Units Certificate, the Holder of this Stock Purchase Units Certificate
shall deliver to the Purchase Contract Agent at the Corporate Trust Office an
Election to Settle Early form set forth below and any other documents requested
by the Purchase Contract Agent duly completed and accompanied by payment in the
form of immediately available funds payable to the order of the Company in an
amount (the "EARLY SETTLEMENT AMOUNT") equal to (i) the product of (A) $25 times
(B) the number of Purchase Contracts with respect to which the Holder has
elected to effect Early Settlement, plus (ii) if such delivery is made with
respect to any Purchase Contracts during the period from the close of business
on any Record Date for any Payment Date to the opening of business on such
Payment Date, an amount equal to the Purchase Contract Payments payable on such
Payment Date with respect to such Purchase Contracts.

         Upon Early Settlement of Purchase Contracts by a Holder of the related
Securities, the Pledged Preferred Securities, Pledged [Subordinated] Notes or
the appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be,
underlying such Securities shall be released from the Pledge as provided in the
Pledge Agreement and the Holder shall be entitled to receive a number of shares
of Common Stock on account of each Purchase Contract forming part of a Stock
Purchase Unit as to which Early Settlement is effected equal to ______ share of
Common Stock per 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 provided in the Purchase Contract Agreement.

         Upon registration of transfer of this Stock Purchase 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 Purchase Contract
Agent pursuant to the Purchase Contract Agreement), under 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 Stock Purchase 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 Stock Purchase Units Certificate, by its acceptance
hereof, authorizes the Purchase Contract Agent to enter into and perform the
related Purchase Contracts forming part of the Stock Purchase Units evidenced
hereby on its behalf as its attorney-in-fact, expressly withholds any

                                    A-12

<Page>

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
thereof, covenants and agrees to perform his obligations under such Purchase
Contracts, consents to the provisions of the Purchase Contract Agreement,
authorizes the Purchase Contract Agent to enter into and perform the Purchase
Contract Agreement and the Pledge Agreement on its behalf as its
attorney-in-fact, and consents to the Pledge of the Preferred Securities or
the appropriate Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio, as the case may be,
underlying this Stock Purchase 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 to the
aggregate liquidation amount of the Pledged Preferred Securities or the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be, on the
Purchase Contract Settlement Date shall be paid 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.

         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
Purchase Contracts.

         The Purchase Contracts shall be governed by, and construed in
accordance with, the laws of the State of New York, without regard to conflicts
of laws principles thereof.

         The Company, the Purchase Contract Agent and its Affiliates and any
agent of the Company or the Purchase Contract Agent may treat the Person in
whose name this Stock Purchase Units Certificate is registered as the owner of
the Stock Purchase Units evidenced hereby for the purpose of receiving payments
of distributions payable quarterly on the Preferred Securities, receiving
payments of Purchase Contract Payments, performance of the Purchase Contracts
and for all other purposes whatsoever, whether or not any payments in respect
thereof be overdue and notwithstanding any notice to the contrary, and neither
the Company, the Purchase Contract 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
at the offices of the Purchase Contract Agent.

                         TREASURY STOCK PURCHASE UNITS

         This Treasury Stock Purchase Units Certificate certifies that
__________________ is the registered Holder of the number of Treasury Stock
Purchase Units set forth above. Each Treasury Stock Purchase Unit consists of
(i) a 1/40 undivided beneficial ownership interest of a Treasury Security
having a principal amount at maturity equal to $1,000, subject to the Pledge
of such Treasury Security by such Holder pursuant to the Pledge Agreement, and
(ii) the rights and obligations of the Holder under one Purchase Contract with
Cinergy Corp., a Delaware corporation (the "COMPANY"). All capitalized terms
used herein which are defined in the Purchase Contract Agreement (as defined
on

<Page>

the reverse hereof) have the meaning set forth therein.

         Pursuant to the Pledge Agreement, the Treasury Securities constituting
part of each Treasury Stock Purchase Unit evidenced hereby have been pledged to
the Collateral Agent, for the benefit of the Company, to secure the obligations
of the Holder under the Purchase Contract comprising part of such Treasury Stock
Purchase Unit. Each Purchase Contract evidenced hereby obligates the Holder of
this Treasury Stock Purchase Units Certificate to purchase, and the Company, to
sell, on _____________ (the "PURCHASE CONTRACT SETTLEMENT DATE"), at a price
equal to $25 (the "STATED AMOUNT"), a number of shares of Common Stock, without
par value ("COMMON STOCK"), of the Company, equal to the Settlement Rate, unless
prior to or on the Purchase Contract Settlement Date there shall have occurred a
Termination Event or an Early Settlement with respect to the Treasury Stock
Purchase Unit 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 (the "PURCHASE PRICE") for the shares of Common Stock purchased
pursuant to each Purchase Contract evidenced hereby, if not paid earlier, shall
be paid on the Purchase Contract Settlement Date by application of the proceeds
from the Treasury Securities at maturity pledged to secure the obligations of
the Holder under such Purchase Contract of the Treasury Stock Purchase Unit of
which such Purchase Contract is a part.

         The Company shall pay, on each Payment Date, in respect of each
Purchase Contract forming part of a Treasury Stock Purchase Unit evidenced
hereby, an amount (the "PURCHASE CONTRACT PAYMENTS") equal to ___% per year of
the Stated Amount. Such Purchase Contract Payments shall be payable to the
Person in whose name this Treasury Stock Purchase Units Certificate is
registered at the close of business on the Record Date for such Payment Date.
The Company may, at its option, defer such Purchase Contract Payments.

         Distributions on the Preferred Securities and the Applicable Ownership
Interest (as specified in clause (B) of the definition of such term) and the
Purchase Contract Payments will be payable at the office of the Purchase
Contract Agent in New York City or, at the option of the Company, by check
mailed to the address of the Person entitled thereto as such address appears on
the Security Register.

         Reference is hereby made to the further provisions set forth on the
reverse hereof, which further provisions shall for all purposes have the same
effect as if set forth at this place.

         Unless the certificate of authentication hereon has been executed by
the Purchase Contract Agent by manual signature, this Treasury Stock Purchase
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 TREASURY STOCK PURCHASE UNITS CERTIFICATE)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of ___________, 2001 (as may be supplemented from
time to time, the "PURCHASE CONTRACT AGREEMENT") between the Company and
[           ], as Purchase Contract Agent (including its successors thereunder,
herein called the "PURCHASE CONTRACT AGENT"), to which the 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 Purchase Contract Agent, the Company
and the Holders and of the terms upon which the Treasury Stock Purchase Units
Certificates are, and are to be, executed and delivered.

         Unless a Cash Settlement or an Early Settlement has occurred, each
Purchase Contract evidenced hereby obligates the Holder of this Treasury Stock
Purchase Units Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Stated Amount (the "PURCHASE
PRICE") a number of shares of Common Stock equal to the Settlement Rate, unless
prior to the Purchase Contract Settlement Date, there shall have occurred a
Termination Event with respect to the Security of which such Purchase Contract
is a part or an Early Settlement shall have occurred. The "SETTLEMENT RATE" is
equal to:

              (1) if the Applicable Market Value (as defined below) is greater
         than or equal to $______ (the "THRESHOLD APPRECIATION PRICE"), ______
         share of Common Stock per Purchase Contract;

              (2) if the Applicable Market Value is less than the Threshold
         Appreciation Price but greater than $______ (the "REFERENCE PRICE"),
         the number of shares of Common Stock per Purchase Contract having a
         value, based on the Applicable Market Value, equal to $25; and

              (3) if the Applicable Market Value is less than or equal to the
         Reference Price, then ______ share 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 Section 5.09 of the Purchase Contract
Agreement.

         Each Purchase Contract evidenced hereby, which is settled either
through Early Settlement or Cash Settlement, shall obligate the Holder of the
related Treasury Stock Purchase Unit to purchase at the Purchase Price for cash,
and the Company to sell, a number of shares of Common Stock equal to the Early
Settlement Rate or the Settlement Rate, as applicable.

                                     B-5

<Page>

         The "APPLICABLE MARKET VALUE" means the average of the Closing Prices
per share of Common Stock on each of the 20 consecutive Trading Days ending on
the third Trading Day immediately preceding the Purchase Contract Settlement
Date.

         The "CLOSING PRICE" per share of Common Stock on any date of
determination means the:

              (1) closing sale price as of the close of the principal trading
         session (or, if no closing price is reported, the last reported sale
         price) per share on the New York Stock Exchange, Inc. (the "NYSE") on
         such date;

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

              (3) if the Common Stock is not so listed on a United States
         national or regional securities exchange, the closing sale price per
         share as reported by The Nasdaq National Market;

              (4) 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

              (5) if such bid price is not available, the average of the
         mid-point of the last bid and ask prices of the Common Stock on such
         date from at least three nationally recognized independent investment
         banking firms retained for this purpose by the Company.

         A "TRADING DAY" means a day on which the Common Stock (1) 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 (2) 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.

         In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Treasury Stock Purchase Unit shall pay the Purchase Price for
the shares of the Common Stock purchased pursuant to each Purchase Contract
evidenced hereby either by effecting a Cash Settlement or an Early Settlement
of each such Purchase Contract or by applying a principal amount of the
Pledged Treasury Securities underlying such Holder's Treasury Stock Purchase
Unit equal to the Stated Amount of such Purchase Contract to the purchase of
the Common Stock. A Holder of Treasury Stock Purchase Unit who does not
effect, prior to or on 11:00 a.m. (New York City time) on the fifth Business
Day immediately preceding the Purchase Contract Settlement Date, an effective
Cash Settlement, or who does not effect on or prior to 5:00 p.m. (New York
City time) on the seventh Business Day prior to the Purchase Contract
Settlement Date an effective Early Settlement, shall pay the Purchase Price
for the

                                     B-6

<Page>

shares of Common Stock to be issued under the related Purchase Contract from
the proceeds of the Pledged Treasury Securities.

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

         Each Purchase Contract evidenced hereby and all obligations and rights
of the Company and the Holder thereunder shall terminate if a Termination Event
shall occur. Upon the occurrence of a Termination Event, the Company shall give
written notice to the Purchase Contract Agent and to the Holders, at their
addresses as they appear in the Security Register. Upon and after the occurrence
of a Termination Event, the Collateral Agent shall release the Pledged Treasury
Securities (as defined in the Pledge Agreement) forming a part of each Treasury
Stock Purchase Unit. A Treasury Stock Purchase Unit shall thereafter represent
the right to receive the interest in the Treasury Security forming a part of
such Treasury Stock Purchase Unit, in accordance with the terms of the Purchase
Contract Agreement and the Pledge Agreement.

         The Treasury Stock Purchase Units Certificates are issuable only in
registered form and only in denominations of a single Treasury Stock Purchase
and any integral multiple thereof. The transfer of any Treasury Stock Purchase
Certificate will be registered and Treasury Stock Purchase Certificates may be
exchanged as provided in the Purchase Contract Agreement. The Security 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 Purchase Contract Agent may require payment of a sum
sufficient to cover any tax or other governmental charge payable in connection
therewith. A Holder who elects to substitute Preferred Securities or
[Subordinated] Notes, for Treasury Securities, thereby recreating Stock Purchase
Units, shall be responsible for any fees or expenses associated therewith.
Except as provided in the Purchase Contract Agreement, for so long as the
Purchase Contract underlying a Treasury Stock Purchase Unit remains in effect,
such Treasury Stock Purchase Unit shall not be separable into its constituent
parts, and the rights and obligations of the Holder of such Treasury Stock
Purchase Unit in respect of the Treasury Security and the Purchase Contract
constituting such Treasury Stock Purchase Unit may be transferred and exchanged
only as a Treasury Stock Purchase Unit.

         A Holder of Treasury Stock Purchase Units may recreate Stock Purchase
Units by delivering to the Securities Intermediary Preferred Securities with
an aggregate liquidation amount, or [Subordinated] Notes with an aggregate
principal amount, equal to the aggregate principal amount at maturity of the
Pledged Treasury Securities in exchange for the release of such Pledged
Treasury Securities in accordance with the terms of the Purchase Contract
Agreement and the Pledge Agreement. From and after such substitution, the
Holder's Security shall be referred to as a "STOCK

                                     B-7

<Page>

PURCHASE UNIT". Any such creation of Stock Purchase Units may be effected only
in multiples of 40 Treasury Stock Purchase Units for 40 Stock Purchase Units.

         A Holder of Stock Purchase Units may recreate Treasury Stock Purchase
Units by delivering to the Securities Intermediary Treasury Securities in an
aggregate principal amount equal to the aggregate liquidation amount of the
Pledged Preferred Securities or the aggregate principal amount at maturity of
the Pledged [Subordinated] Notes, as the case may be, in accordance with the
terms of the Purchase Contract Agreement and the Pledge Agreement. Any such
recreation of Treasury Stock Purchase Units may be effected only in multiples of
40 Stock Purchase Units for 40 Treasury Stock Purchase Units.

         If a Tax Event Redemption has occurred, a Treasury Stock Purchase Unit
Holder may not recreate Stock Purchase Units, and a Stock Purchase Unit Holder
may not create a Treasury Stock Purchase Unit.

         The Company shall pay, on each Payment Date, the Purchase Contract
Payments payable in respect of each Purchase Contract to the Person in whose
name the Treasury Stock Purchase Units Certificate evidencing such Purchase
Contract is registered at the close of business on the Record Date for such
Payment Date. Purchase Contract Payments will be payable at the office of the
Purchase Contract Agent in New York City or, at the option of the Holder, by
check mailed to the address of the Person entitled thereto at such address as it
appears on the Security Register.

         The Company has the right to defer payment of all or part of the
Purchase Contract Payments in respect of each Purchase Contract until no later
than the Purchase Contract Settlement Date. If the Company so elects to defer
Purchase Contract Payments, the Company shall pay additional Purchase Contract
Payments on such deferred installments of Purchase Contract Payments at a rate
equal to ___% per annum, compounding quarterly, until such deferred installments
are paid. In the event that the Company elects to defer the payment of Purchase
Contract Payments on the Purchase Contracts until the Purchase Contract
Settlement Date), each Holder will receive on the Purchase Contract Settlement
Date the aggregate amount of accrued and unpaid Purchase Contract Payments.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive and the obligation of the Company to pay any Purchase
Contract Payments, shall immediately and automatically terminate, without the
necessity of any notice or action by any Holder, the Purchase Contract Agent or
the Company, if, on or prior to the Purchase Contract Settlement 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 Purchase Contract Agent, the Collateral
Agent and the Holders, at their addresses as they appear in the Security
Register. Upon and after the occurrence of a Termination Event, the Collateral
Agent shall release the Treasury Securities from the Pledge in accordance with
the provisions of the Pledge Agreement. A Treasury Stock

                                      B-8
<Page>

Purchase Unit shall thereafter represent the right to receive the interest in
the Treasury Security forming a part of such Treasury Stock Purchase Unit, in
accordance with the terms of the Purchase Contract Agreement and the Pledge
Agreement.

         Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
underlying Securities may be settled early ("EARLY SETTLEMENT") as provided in
the Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Stock
Purchase Units Certificate, the Holder of this Treasury Stock Purchase Units
Certificate shall deliver to the Purchase Contract Agent at the Corporate Trust
Office an Election to Settle Early form set forth below and any other documents
requested by the Purchase Contract Agent duly completed and accompanied by
payment in the form of immediately available funds payable to the order of the
Company in an amount (the "EARLY SETTLEMENT AMOUNT") equal to (i) the product of
(A) $25 times (B) the number of Purchase Contracts with respect to which the
Holder has elected to effect Early Settlement, plus (ii) if such delivery is
made with respect to any Purchase Contracts during the period from the close of
business on any Record Date for any Payment Date to the opening of business on
such Payment Date, an amount equal to the Purchase Contract Payments payable on
such Payment Date with respect to such Purchase Contracts.

         Upon Early Settlement of Purchase Contracts by a Holder of the related
Securities, the Pledged Treasury Securities underlying such Securities shall be
released from the Pledge as provided in the Pledge Agreement and the Holder
shall be entitled to receive a number of shares of Common Stock on account of
each Purchase Contract forming part of a Treasury Stock Purchase Unit as to
which Early Settlement is effected equal to ______ share of Common Stock per
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 provided in the Purchase Contract Agreement.

         Upon registration of transfer of this Treasury Stock Purchase
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 Purchase
Contract Agent pursuant to the Purchase Contract Agreement), under 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 Treasury Stock Purchase 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 Treasury Stock Purchase Units Certificate, by its
acceptance hereof, authorizes the Purchase Contract Agent to enter into and
perform the related Purchase Contracts forming part of the Treasury Stock
Purchase 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 thereof, covenants and

                                      B-9
<Page>

agrees to perform its obligations under such Purchase Contracts, consents to
the provisions of the Purchase Contract Agreement, authorizes the Purchase
Contract Agent to enter into and perform the Purchase Contract Agreement and
the Pledge Agreement on its behalf as its attorney-in-fact, and consents to the
Pledge of the Treasury Securities underlying this Treasury Stock Purchase 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 to the aggregate principal amount of the Pledged Treasury Securities
on the Purchase Contract Settlement Date shall be paid 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.

         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
Purchase Contracts.

         The Purchase Contracts shall for all purposes be governed by, and
construed in accordance with, the laws of the State of New York, without regard
to conflicts of laws principles thereof.

         The Company, the Purchase Contract Agent and its Affiliates and any
agent of the Company or the Purchase Contract Agent may treat the Person in
whose name this Treasury Stock Purchase Units Certificate is registered as the
owner of the Treasury Stock Purchase Units evidenced hereby for the purpose of
receiving payments of interest on the Treasury Securities, receiving payments of
Purchase Contract Payments, performance of the Purchase Contracts and for all
other purposes whatsoever, whether or not any payments in respect thereof be
overdue and notwithstanding any notice to the contrary, and neither the Company,
the Purchase Contract 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
at the offices of the Purchase Contract Agent.

                  (i) any Pledged Preferred Securities or security entitlements
         with respect thereto or the Applicable Ownership Interest (as specified
         in clause

                                      15
<Page>

         (A) of the definition of such term) of the Treasury Portfolio (if a
         Tax Event Redemption has occurred and the Treasury Portfolio has
         become a component of the Stock Purchase Units) or the Pledged
         [Subordinated] Notes (if the Trust has been dissolved and liquidated,
         and the [Subordinated] Notes or security entitlements with respect
         thereto have become a component of the Stock Purchase Units);

                 (ii) any Pledged Treasury Securities, and

                (iii) payments by Holders (or the Permitted Investments of

to such Holders in accordance with their respective interests, free and clear of
any lien, pledge or security interest or other interest created hereby;
provided, however, if any Holder shall be entitled to receive less than $1,000
with respect to his interest in the Applicable Ownership Interest (as specified
in clause (A) of the definition of such term) of the Treasury Portfolio, the
Purchase Contract Agent shall have the right to dispose of such interest for
cash and deliver to such Holder cash in lieu of delivering the Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio.

         (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
Preferred Securities, the Applicable Ownership Interest (as specified in clause
(A) of the definition of such term) of the Treasury Portfolio, the Pledged
[Subordinated] Notes, the Pledged Treasury Securities or payments by Holders (or
the Permitted Investments of such payments) pursuant to Section 5.05 hereof, as
the case may be, as provided by this Section 5.04, the Purchase Contract Agent
shall:

                  (i) use its best efforts to obtain 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
         5.04, and shall deliver such opinion to the Collateral Agent within ten
         days after the occurrence of such Termination Event, and if (A) the
         Purchase Contract Agent shall be unable to obtain such opinion within
         ten days after the occurrence of such Termination Event or (B) the
         Collateral Agent shall continue, after delivery of such opinion, to
         refuse to effectuate the release and Transfer of all Pledged Preferred
         Securities,

         Applicable Ownership Interest (as specified in clause (A) of the
         definition of such term) of the Treasury Portfolio, all the
         Pledged [Subordinated] Notes, the Pledged Treasury Securities, the
         payments by Holders or the Permitted Investments of such payments
         pursuant to Section 5.05 hereof or the Proceeds of any of the
         foregoing, as the case may be, as provided in this Section 5.04, then
         the Purchase Contract Agent shall within fifteen days after the
         occurrence of such Termination Event commence an action or proceeding
         in the court having jurisdiction of the Company's case under the

         payments by Holders or the Permitted Investments of such payments
         pursuant to Section 5.05 hereof, or as the case may be, as provided by
         this Section 5.04; or

                 (ii) commence an action or proceeding like that described in
         clause 5.04(b)(i) hereof within ten days after the occurrence of such
         Termination Event.

         SECTION 5.05. CASH SETTLEMENT.

         (a) Upon receipt by the Collateral Agent of (1) a notice from the
Purchase Contract Agent promptly after the receipt by the Purchase Contract
Agent of a notice from a Holder of Stock Purchase Units that such Holder has
elected, in accordance with the procedures specified in Section 5.02(a)(i) or

or a Stock Purchase Unit, if a Tax Event Redemption has occurred, of the
Purchase Price in lawful money of the United States by certified or cashier's

order of the Securities Intermediary, then the Collateral Agent shall:

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

                 (ii) release from the Pledge the Stock Purchase Unit holder's
         or the Treasury Stock Purchase Unit holder's related Pledged Preferred
         Securities,

                                      17
<Page>

         Applicable Ownership Interest (as specified in clause (A) of the
         definition of such term) of the Treasury Portfolio, the Pledged
         [Subordinated] Notes or Pledged Treasury Securities, as applicable, as

         to this Section 5.05(a); and

         benefit of such Holder, in each case free and clear of the Pledge
         created hereby, for distribution to such Holder.

         Upon the request of the Securities Intermediary, the Company shall
instruct the Securities Intermediary in writing as to the type of Permitted
Investments in which any such Cash shall be invested; provided, however, that if
the Company fails to deliver such written instructions by 10:30 a.m. (New York
City time), the Securities Intermediary shall invest such Cash in the Permitted
Investments described in clause (6) of the definition of Permitted Investments.

         Upon receipt of the proceeds upon the maturity of the Permitted
Investments on the Purchase Contract Settlement Date, the Collateral Agent shall
(A) instruct the Securities Intermediary to pay the portion of such proceeds and
deliver any certified or cashier's checks received, in an aggregate amount equal
to the Purchase Price, to the Company on the Purchase Contract Settlement Date,
and (B) instruct the Securities Intermediary to release any amounts in excess of
the Purchase Price earned from such Permitted Investments to the Purchase
Contract Agent for distribution to such Holder.

          (b) If a Holder of Stock Purchase Units (if a Tax Event Redemption
shall not have occurred) notifies the Purchase Contract Agent as provided in
paragraph 5.02(a)(i) of the Purchase Contract Agreement of its intention to pay
the Purchase Price in cash, but fails to make such payment as required by
paragraph 5.02(a)(ii) of the Purchase Contract Agreement, such Holder shall be
deemed to have consented to the disposition of such Holder's Pledged Preferred
Securities or Pledged [Subordinated] Notes in accordance with paragraph
5.02(a)(iii) of the Purchase Contract Agreement.

          (c) If a Holder of a Treasury Stock Purchase Unit or a Holder of Stock
Purchase Unit (if a Tax Event Redemption shall have occurred) notifies the
Purchase Contract Agent as provided in paragraph 5.02(d)(i) of the Purchase
Contract Agreement of its intention to pay the Purchase Price in cash, but fails
to make such payment as required by paragraph 5.02(d)(ii) of the Purchase
Contract Agreement,

                                      18
<Page>

such Holder shall be deemed to have elected to pay the Purchase Price in
accordance with paragraph 5.02(d)(iii) of the Purchase Contract Agreement.

         (d) As soon as practicable after 11:00 a.m. (New York City time) on
the fifth Business Day immediately preceding the Purchase Contract Settlement
Date, the Securities Intermediary shall deliver to the Purchase Contract Agent a
notice, substantially in the form of Exhibit E hereto, stating (i) the amount of
cash that it has received with respect to the Cash Settlement of Stock Purchase
Units and (ii) the amount of cash that it has received with respect to the Cash
Settlement of Treasury Stock Purchase Units.

         SECTION 5.06. EARLY SETTLEMENT. Upon receipt by the Collateral Agent of
a notice from the Purchase Contract Agent that a Holder of Securities has
elected to effect Early Settlement of its obligations under the Purchase
Contracts forming a part of such Securities in accordance with the terms of the
Purchase Contracts and Section 5.07 of the Purchase Contract Agreement (which
notice shall set forth the number of such Purchase Contracts as to which such
Holder has elected to effect Early Settlement), and that the Purchase Contract
Agent has received from such Holder, and paid to the Company as confirmed in
writing by the Company, the related Early Settlement Amounts pursuant to the
terms of the Purchase Contracts and the Purchase Contract Agreement and that all
conditions to such Early Settlement have been satisfied, then the Collateral
Agent shall release from the Pledge, (1) Pledged Preferred Securities or the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definitions at such term) of the Treasury Portfolio or Pledged [Subordinated]
Notes in the case of a Holder of Stock Purchase Units or (2) Pledged Treasury
Securities, in the case of a Holder of Treasury Stock Purchase Units, with a
Value equal to the product of (x) the Stated Amount times (y) the number of
Purchase Contracts as to which such Holder has elected to effect Early
Settlement, and shall instruct the Securities Intermediary to Transfer all such
Pledged Preferred Securities or the appropriate Applicable Ownership Interest
(as specified in clause (A) of the definitions at such term) of the Treasury
Portfolio or Pledged [Subordinated] Notes or Pledged Treasury Securities, as the
case may be, to the Purchase Contract Agent for the benefit of such Holder, in
each case free and clear of the Pledge created hereby, for distribution to such
Holder. A Treasury Stock Purchase Unit holder may settle early only in integral
multiples of 40 Purchase Contracts.

         SECTION 5.07. APPLICATION OF PROCEEDS IN SETTLEMENT OF PURCHASE
CONTRACTS.

         (a) If a Holder of Stock Purchase Units (if a Tax Event Redemption has
not occurred) has not elected to make an effective Cash Settlement by notifying
the

                                      19
<Page>

Purchase Contract Agent in the manner provided for in Section 5.02(a)(i) in the
Purchase Contract Agreement, or has given such notice but failed to deliver the
required cash prior to 11:00 a.m. (New York City time) on the fifth Business
Day immediately preceding the Purchase Contract Settlement Date, such Holder
shall be deemed to have elected to pay for the shares of Common Stock to be
issued under such Purchase Contracts from the Proceeds of the remarketing of
the related Pledged Preferred Securities or Pledged [Subordinated] Notes. Upon
written notice of such event from the Purchase Contract Agent, the Collateral
Agent shall instruct the Securities Intermediary to Transfer the related
Pledged Preferred Securities or Pledged [Subordinated] Notes to the Remarketing
Agent for remarketing. Upon receiving such Pledged Preferred Securities or
Pledged [Subordinated] Notes, the Remarketing Agent, pursuant to the terms of
the Remarketing Agreement, will use reasonable efforts to remarket such Pledged
Preferred Securities or Pledged [Subordinated] Notes. The Remarketing Agent
will deposit the Proceeds of such remarketing (less $[0.0625] per each
Preferred Security remarketed, which shall be retained by the Remarketing Agent
as a fee for its services in the Remarketing) in the Collateral Account, and
the Securities Intermediary shall invest the Proceeds of the remarketing in
Permitted Investments in clause (6) of the definition of Permitted Investments.
On the Purchase Contract Settlement Date, the Purchase Contract Agent shall
give written direction to the Collateral Agent specifying the instruction the
Collateral Agent shall give to the Securities Intermediary in order to apply a
portion of the Proceeds from such remarketing equal to the aggregate
liquidation amount of the Preferred Securities or aggregate principal amount of
such Pledged [Subordinated] Note to satisfy in full such Holder's obligations
to pay the Purchase Price to purchase the shares of Common Stock under the
related Purchase Contracts and the balance of the Proceeds from the
remarketing, if any, that shall be transferred to the Purchase Contract Agent
for the benefit of such Holder for distribution to such Holder.

         If the Remarketing Agent advises the Collateral Agent in writing that
there has been a Failed Remarketing, thus resulting in an event of default under
the Purchase Contract Agreement and hereunder, the Collateral Agent, for the
benefit of the Company shall, at the written direction of the Company, use
commercially reasonable efforts to dispose of the Pledged Preferred Securities
or Pledged [Subordinated] Notes in accordance with applicable law and apply the
proceeds from such disposition towards such Holder's obligations to pay the
Purchase Price for the shares of Common Stock.

          (b) If a Holder of a Treasury Stock Purchase Unit or a Holder of Stock
Purchase Unit (if a Tax Event Redemption has occurred) has not elected to make
an effective Cash Settlement by notifying the Purchase Contract Agent in the
manner provided for in Section 5.02(d)(i) of the Purchase Contract Agreement, or
has given

                                      20
<Page>

such notice but failed to make such payment in the manner required by Section
5.02(d)(ii) of the Purchase Contract Agreement, such Holder shall be deemed to
have elected to pay for the shares of Common Stock to be issued under such
Purchase Contracts from the Proceeds of the related Pledged Treasury Securities
or such Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be.
Promptly, after 11:00 a.m. (New York City time) on the Business Day immediately
prior to the Purchase Contract Settlement Date, the Securities Intermediary
shall invest the Cash Proceeds of the maturing Pledged Treasury Securities or
such Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, as the case may be, in
Permitted Investments in clause 6 of the definition of Permitted Investments,
unless prior to 10:30 a.m. (New York City time), the Company shall otherwise
instruct the Securities Intermediary as to the type of Permitted Investments in
which any such Cash Proceeds shall be invested. Without receiving any
instruction from any such Holder, the Collateral Agent shall apply the Proceeds
of the related Pledged Treasury Securities or such Applicable Ownership
Interest (as specified in clause (A) of the definition of such term) of the
Treasury Portfolio, as the case may be, to the settlement of such Purchase
Contracts on the Purchase Contract Settlement Date. In the event the sum of the
Proceeds from the related Pledged Treasury Securities or such Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio as the case may be, and the investment earnings from
the investment in Permitted Investments exceeds the aggregate Purchase Price of
the Purchase Contracts being settled thereby, the Collateral Agent shall
instruct the Securities Intermediary to distribute such excess, when received,
to the Purchase Contract Agent for the benefit of such Holder for distribution
to such Holder.

         SECTION 5.08. TAX EVENT REDEMPTION. If the Securities Intermediary
receives written notice that a Tax Event Redemption has occurred prior to the
Purchase Contract Settlement Date, the Securities Intermediary shall apply the
Redemption Amount to purchase the Treasury Portfolio and the Securities
Intermediary shall credit the Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) of the Treasury Portfolio to the
Collateral Account and shall transfer the Applicable Ownership Interest (as
specified in clause (B) of the definition of such term) of the Treasury
Portfolio to the Purchase Contract Agent for distribution to the Holders of the
Stock Purchase Units. Upon credit to the Collateral Account of the Applicable
Ownership Interest (as specified in clause (A) of the definition of such term)
of the Treasury Portfolio having a Value equal to the liquidation amount of the
Pledged Preferred Securities or the aggregate principal amount of the Pledged
[Subordinated] Notes, the Securities Intermediary shall release the Pledged
Preferred Securities or the Pledged [Subordinated] Notes, as applicable, from
the Collateral Account and shall

                                      21
<Page>

promptly transfer the Pledged Preferred Securities to the Trust and the Pledged
[Subordinated] Notes to the Company, as applicable.

         SECTION 6.01. VOTING RIGHTS. The Purchase Contract Agent may exercise,
or refrain from exercising, any and all voting and other consensual rights
pertaining to the Pledged Preferred Securities or the Pledged [Subordinated]
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

shall not refrain from exercising such right, as the case may be, if, in the
judgment of the Purchase Contract Agent, such action would impair or otherwise
have a material adverse effect on the value of all or any of the Pledged
Preferred Securities or the Pledged [Subordinated] Notes; and provided, further,
that the Purchase Contract Agent shall give the Company and the Collateral Agent
at least five Business Days' prior written notice of the manner in which it
intends to exercise, or its reasons for refraining from exercising, any such
right. Upon receipt of any notices and other communications in respect of any
Pledged Preferred Securities or the Pledged [Subordinated] Notes, including
notice of any meeting at which holders of the Preferred Securities or the
[Subordinated] Notes are entitled to vote or solicitation of consents, waivers
or proxies of holders of the Preferred Securities or [Subordinated] 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 Preferred Securities or the
Pledged [Subordinated] Notes (in form and substance satisfactory to the
Collateral Agent) as are prepared by the Purchase Contract Agent with respect to
the Pledged Preferred Securities or the Pledged [Subordinated] Notes.

         SECTION 7.1.  RIGHTS AND REMEDIES OF THE COLLATERAL AGENT.

         (a) In addition to the rights and remedies specified in Section 5.07
hereof or otherwise available at law or in equity, after an event of default (as
specified in Section 7.01(b) below) hereunder, the Collateral Agent shall have
all of the rights and remedies with respect to the Collateral of a secured party
under the UCC (whether or not the UCC is in effect in the jurisdiction where the
rights and remedies are asserted) and the TRADES Regulations and such additional
rights and remedies to which a secured party is entitled under the laws in
effect in any jurisdiction where any rights and remedies hereunder may be
asserted. Without limiting the generality of the foregoing, such remedies may
include, to the extent permitted by applicable law, (1) retention of the Pledged
Preferred Securities, Pledged [Subordinated] Notes, Pledged Treasury Securities
or the appropriate Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) in full satisfaction of the Holders' obligations
under the Purchase Contracts and the Purchase Contract Agreement or (2) sale of
the Pledged Preferred Securities, Pledged [Subordinated] Notes, Pledged Treasury
Securities or the appropriate Applicable Ownership Interest (as specified in
clause (A) of the definition of such term) in one or more public or private

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

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

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

         SECTION 7.2. SUBSTITUTION OF [SUBORDINATED] NOTES OR TREASURY
PORTFOLIO. If the Trust shall have been dissolved and liquidated prior to the
Purchase Contract Settlement Date, the Securities Intermediary shall transfer to
the Collateral Agent [Subordinated] Notes having a Value equal to the
liquidation amount of the Pledged Preferred Securities for credit to the
Collateral Account. Upon credit to the Collateral Account of such [Subordinated]
Notes, the Collateral Agent shall release the Pledged Preferred Securities from
the Collateral Account and shall promptly transfer the same to the Trust.

         Notwithstanding the foregoing, in the event of a dissolution and
liquidation of the Trust, if a Liquidation Distribution is to be distributed in
lieu of the [Subordinated] Notes as provided for in the Declaration, the
Liquidation Distribution shall be credited to the Collateral Account by the
Property Trustee, on or prior to 12:30 p.m., New York City time on the date of
distribution of the Liquidation Distribution, by federal funds check or wire
transfer of immediately available funds. The Collateral Agent is hereby
authorized to present the Pledged Preferred Securities for payment as may be
required by their terms. Upon receipt of such funds, the Pledged Preferred
Securities shall be released from the Collateral Account. In the event such
funds are credited to the Collateral Account, the Collateral Agent, at the
written direction of the Company, shall instruct the Securities Intermediary to
(a) apply an amount equal to the Redemption Amount of such Liquidation
Distribution to purchase the Treasury Portfolio from the Quotation Agent for
credit to the Collateral Account and (b) promptly remit

                                      24

<Page>

the remaining portion of such Liquidation Distribution, if any, to the
Purchase Contract Agent for payment to the Holders of Stock Purchase Units.

         SECTION 7.3. TAX EVENT REDEMPTION. Upon the occurrence of a Tax Event
Redemption prior to the Purchase Contract Settlement Date, the Redemption
Amount, plus any accumulated and unpaid distributions, or any accrued and unpaid
interest, as the case may be, payable on the Tax Event Redemption Date with
respect to the Applicable Principal Amount shall be credited to the Collateral
Account by the Property Trustee or, in case there has been a dissolution of the
Trust and the distribution of the related [Subordinated] Notes, by the Indenture
Trustee, on or prior to 12:30 p.m., New York City time on such Tax Event
Redemption Date, by federal funds check or wire transfer of immediately
available funds. The Collateral Agent is hereby authorized to present the
Pledged Preferred Securities or the Pledged [Subordinated] Notes for payment as
may be required by their respective terms. Upon receipt of such funds, the
Pledged Preferred Securities or Pledged [Subordinated] Notes, as the case may
be, shall be released from the Collateral Account. In the event such funds are
credited to the Collateral Account, the Collateral Agent, at the written
direction of the Company, shall instruct the Securities Intermediary to (a)
apply an amount equal to the Redemption Amount of such funds to purchase the
Treasury Portfolio from the Quotation Agent for credit to the Collateral Account
and (b) promptly remit the remaining portion of such funds, if any, to the
Purchase Contract Agent for payment to the Holders of Stock Purchase Units.

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

Collateral and is the sole beneficial owner of, or has the right to Transfer,
the Collateral it Transfers to the Securities Intermediary for credit to the
Collateral Account, free and clear of any security interest, lien, encumbrance,
call, liability to pay money or other restriction other than the security
interest and lien granted under Article 2 hereof;

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

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

         SECTION 8.2. COVENANTS. The Holders from time to time, acting through
the Purchase Contract Agent as their attorney-in-fact (it being understood that
the Purchase Contract Agent shall not be liable for any covenant made by or on
behalf of a

                                      26

Holder), hereby covenant to the Collateral Agent that for so long as the
Collateral remains subject to the Pledge:

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

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

                                    ARTICLE 9

              THE COLLATERAL AGENT AND THE SECURITIES INTERMEDIARY

         It is hereby agreed as follows:

         SECTION 9.1. APPOINTMENT, POWERS AND IMMUNITIES. The Collateral Agent
and Securities Intermediary shall act as agent for the Company hereunder with
such powers as are specifically vested in the Collateral Agent and Securities
Intermediary by the terms of this Agreement, together with such other powers as
are reasonably incidental thereto. The Collateral Agent and Securities
Intermediary shall:

         (a) 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 the Collateral Agent and Securities
Intermediary, nor shall the Collateral Agent and Securities Intermediary be
bound by the provisions of any agreement by any party hereto beyond the specific
terms hereof;

         (b) not be responsible for any recitals contained in this Agreement,
or in any certificate or other document referred to or provided for in, or
received by it under, this Agreement, the Securities or the Purchase Contract
Agreement, or for the value, validity, effectiveness, genuineness,
enforceability or sufficiency of this Agreement (other than as against the
Collateral Agent and Securities Intermediary), the Securities or the Purchase
Contract Agreement or any other document referred to or provided for herein or
therein or for any failure by the Company or any other Person (except the
Collateral Agent and Securities Intermediary) to perform any of its obligations

                                      27

<Page>

hereunder or thereunder or for the perfection, priority or, except as expressly
required hereby, maintenance of any security interest created hereunder;

         (c) not be required to initiate or conduct any litigation or
collection proceedings hereunder (except pursuant to directions furnished under
Section 9.02 hereof, subject to Section 9.06 hereof);

         (d) not be responsible for any action taken or omitted to be taken by
it hereunder or under any other document or instrument referred to or provided
for herein or in connection herewith or therewith, except for its own negligence
or willful misconduct; and

         (e) not be required to advise any party as to selling or retaining, or
taking or refraining from taking any action with respect to, any securities or
other property deposited hereunder.

Subject to the foregoing, during the term of this Agreement, the Collateral
Agent shall take all reasonable action in connection with the safekeeping and
preservation of the Collateral hereunder.

         No provision of this Agreement shall require the Collateral Agent or
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 or Securities Intermediary be liable for any
amount in excess of the Value of the Collateral. Notwithstanding the foregoing,
each of the Collateral Agent and the Securities Intermediary in its individual
capacity hereby waives any right of setoff, bankers' lien, liens or perfection
rights as securities intermediary or any counterclaim with respect to any of the
Collateral.

         SECTION 9.2. INSTRUCTIONS OF THE COMPANY. The Company shall have the
right, by one or more written instruments executed and delivered to the
Collateral Agent, to direct the time, method and place of conducting any
proceeding for the realization of any right or remedy available to the
Collateral Agent, or of exercising any power conferred on the Collateral Agent,
or to direct the taking or refraining from taking of any action authorized by
this Agreement; provided, however, that (i) such direction shall not conflict
with the provisions of any law or of this Agreement and (ii) the Collateral
Agent shall be adequately indemnified as provided herein. Nothing contained in
this Section 9.02 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.

                                      28

         SECTION 9.3. RELIANCE BY COLLATERAL AGENT AND SECURITIES INTERMEDIARY.
Each of the Securities Intermediary and the Collateral Agent shall be entitled
to rely upon any certification, order, judgment, opinion, notice or other
written communication (including, without limitation, any thereof by e-mail or
similar electronic means, telecopy, telex or facsimile) believed by it to be
genuine and correct and to have been signed or sent by or on behalf of the
proper Person or Persons (without being required to determine the correctness of
any fact stated therein) and consult with and rely upon advice, opinions and
statements of legal counsel and other experts selected by the Collateral Agent
and the Securities Intermediary. As to any matters not expressly provided for by
this Agreement, the Collateral Agent and the Securities Intermediary shall in
all cases be fully protected in acting, or in refraining from acting, hereunder
in accordance with instructions given by the Company in accordance with this
Agreement.

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

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

         SECTION 9.6. COMPENSATION AND INDEMNITY. The Company agrees to:

                                      29

<Page>

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

         (b) indemnify and hold harmless the Collateral Agent, the Securities
Intermediary and each of their respective directors, officers, agents and
employees (collectively, the "INDEMNITEES"), harmless from and against any and
all claims, liabilities, losses, damages, fines, penalties and expenses
(including reasonable fees and expenses of counsel) (collectively, "Losses" and
individually, a "LOSS") that may be imposed on, incurred by, or asserted
against, the Indemnitees or any of them for following any instructions or other
directions upon which either the Collateral Agent or the Securities Intermediary
is entitled to rely pursuant to the terms of this Agreement; and

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

         SECTION 9.7. FAILURE TO ACT. In the event of any ambiguity in the
provisions of this Agreement or any dispute between or conflicting claims by or
among the parties hereto or any other Person with respect to any funds or
property deposited hereunder, then at its sole option, each of the Collateral
Agent and the Securities Intermediary shall be entitled, after prompt notice to
the Company and the Purchase Contract Agent, 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 the Collateral Agent and
the Securities Intermediary shall not be or become liable in any way to any of
the parties hereto for its failure or refusal to comply with such conflicting
claims, demands or instructions. The Collateral Agent and the Securities
Intermediary shall be entitled to refuse to act until either:

         (a) such conflicting or adverse claims or demands shall have been
finally determined by a court of competent jurisdiction or settled by agreement
between the conflicting parties as evidenced in a writing satisfactory to the
Collateral Agent or the Securities Intermediary; or

                                      30

<Page>

         (b) the Collateral Agent or the Securities Intermediary shall have
received security or an indemnity satisfactory to it sufficient to save it
harmless from and against any and all loss, liability or reasonable
out-of-pocket expense which it may incur by reason of its acting.

The Collateral Agent and the Securities Intermediary may in addition elect to
commence an interpleader action or seek other judicial relief or orders as the
Collateral Agent or the Securities Intermediary may deem necessary.
Notwithstanding anything contained herein to the contrary, neither the
Collateral Agent nor the Securities Intermediary shall be required to take any
action that is in its opinion contrary to law or to the terms of this Agreement,
or which would in its opinion subject it or any of its officers, employees or
directors to liability.

         SECTION 9.8. RESIGNATION OF COLLATERAL AGENT AND SECURITIES
INTERMEDIARY.

         (a) Subject to the appointment and acceptance of a successor
Collateral Agent as provided below:

             (i)   the Collateral Agent may resign at any time by giving notice
         thereof to the Company and the Purchase Contract Agent as
         attorney-in-fact for the Holders of Securities;

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

             (iii) if the Collateral Agent fails to perform any of its
         material obligations hereunder in any material respect for a period of
         not less than 20 days after receiving written notice of such failure by
         the Purchase Contract Agent and such failure shall be continuing, the
         Collateral Agent may be removed by the Purchase Contract Agent, acting
         at the direction of the Holders of Securities.

The Purchase Contract Agent shall promptly notify the Company of any removal of
the Collateral Agent pursuant to clause (iii) of the immediately preceding
sentence. Upon any such resignation or removal, the Company shall have the right
to appoint a successor Collateral Agent. If no successor Collateral Agent shall
have been so appointed and shall have accepted such appointment within 30 days
after the retiring Collateral Agent's giving of notice of resignation or the
Company or the Purchase Contract Agent giving notice of such removal, then the
retiring Collateral Agent may petition any court of competent jurisdiction for
the appointment of a successor

                                      31

<Page>

Collateral Agent. The Collateral Agent shall be a bank or a national banking
association which has an office (or an agency office) in New York City with a
combined capital and surplus of at least $50,000,000 and shall not be the
Purchase Contract Agent or any of its affiliates. Upon the acceptance of any
appointment as Collateral Agent hereunder by a successor Collateral Agent,
such successor Collateral Agent shall thereupon succeed to and become vested
with all the rights, powers, privileges and duties of the retiring Collateral
Agent, and the retiring Collateral Agent shall take all appropriate action to
transfer any money and property held by it hereunder (including the
Collateral) to such successor Collateral Agent. The retiring Collateral Agent
shall, upon such succession, be discharged from its duties and obligations as
Collateral Agent hereunder. After any retiring Collateral Agent's resignation
hereunder as Collateral Agent, the provisions of this Article 9 shall continue
in effect for its benefit in respect of any actions taken or omitted to be
taken by it while it was acting as the Collateral Agent.

         (b) Subject to the appointment and acceptance of a successor
Securities Intermediary as provided below:

             (i)   the Securities Intermediary may resign at any time by giving
         notice thereof to the Company and the Purchase Contract Agent as
         attorney-in-fact for the Holders of Securities;

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

             (iii) if the Securities Intermediary fails to perform any of its
         material obligations hereunder in any material respect for a period of
         not less than 20 days after receiving written notice of such failure by
         the Purchase Contract Agent and such failure shall be continuing, the
         Securities Intermediary may be removed by the Purchase Contract Agent.

The Purchase Contract Agent shall promptly notify the Company of any removal of
the Securities Intermediary pursuant to clause (iii) of the immediately
preceding sentence. Upon any such resignation or removal, the Company shall have
the right to appoint a successor Securities Intermediary. If no successor
Securities Intermediary shall have been so appointed and shall have accepted
such appointment within 30 days after the retiring Securities Intermediary's
giving of notice of resignation or the Company or the Purchase Contract Agent
giving notice of such removal, then the retiring Securities Intermediary may
petition any court of competent jurisdiction for the appointment of a successor
Securities Intermediary. The Securities Intermediary shall be a bank or a
national banking association which has an office (or an agency office) in New
York

                                      32

<Page>

City with a combined capital and surplus of at least $50,000,000 and shall not
be the Purchase Contract Agent or any of its affiliates. Upon the acceptance
of any appointment as Securities Intermediary hereunder by a successor
Securities Intermediary, such successor Securities Intermediary shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Securities Intermediary, and the retiring
Securities Intermediary shall take all appropriate action to transfer any
money and property held by it hereunder (including the Collateral) to such
successor Securities Intermediary. The retiring Securities Intermediary shall,
upon such succession, be discharged from its duties and obligations as
Securities Intermediary hereunder. After any retiring Securities
Intermediary's resignation hereunder as Securities Intermediary, the
provisions of this Article 9 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting
as the Securities Intermediary.

         SECTION 9.9. RIGHT TO APPOINT AGENT OR ADVISOR. The Collateral Agent
shall have the right to appoint agents or advisors in connection with any of its
duties hereunder, and the Collateral Agent shall not be liable for any action
taken or omitted by, or in reliance upon the advice of, such agents or advisors
selected in good faith. The appointment of agents pursuant to this Section 9.09
shall be subject to prior consent of the Company, which consent shall not be
unreasonably withheld.

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

         SECTION 9.11. EXCULPATION. Anything contained in this Agreement to the
contrary notwithstanding, in no event shall the Collateral Agent or the
Securities Intermediary or their officers, directors, employees or agents be
liable under this Agreement to any third party for indirect, special, punitive,
or consequential loss or damage of any kind whatsoever, including, but not
limited to, lost profits, whether or not the likelihood of such loss or damage
was known to the Collateral Agent or the Securities Intermediary, or any of
them.

                                    AMENDMENT

         SECTION 10.1. AMENDMENT WITHOUT CONSENT OF HOLDERS. Without the consent
of any Holders, the Company, the Collateral Agent, the Securities Intermediary
and the Purchase Contract Agent, at any time and from time to time, may amend
this Agreement, in form satisfactory to the Company, the Collateral Agent, the
Securities Intermediary and the Purchase Contract Agent, to:

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

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

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

         (d) cure any ambiguity (or formal defect), correct or supplement any
provisions herein which may be inconsistent with any other such 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 10.2. AMENDMENT WITH CONSENT OF HOLDERS. With the consent of
the Holders of not less than a majority of the Purchase Contracts at the time
outstanding, by Act of such Holders delivered to the Company, the Purchase
Contract Agent, the Securities Intermediary or the Collateral Agent, as the case
may be, the Company, when duly authorized, the Purchase Contract Agent, the
Securities Intermediary and the Collateral Agent may amend this Agreement for
the purpose of modifying in any manner the provisions of this Agreement or the
rights of the Holders in respect of the Securities; provided, however, that no
such supplemental agreement shall, without the unanimous consent of the Holders
of each Outstanding Security adversely affected thereby:

         (a) Change the amount or type of Collateral underlying a Security
(except for the rights of holders of Stock Purchase Units to substitute the
Treasury Securities for the Pledged Preferred Securities or the Pledged
[Subordinated] Notes, as the case may be, or the rights of Holders of Treasury
Stock Purchase Units to substitute Preferred Securities or [Subordinated] Notes,
as applicable, for the Pledged Treasury Securities),

                                      34

<Page>

impair the right of the Holder of any Security to receive distributions on the
underlying Collateral or otherwise adversely affect the Holder's rights in or
to such Collateral; or

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

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

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

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

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

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

         SECTION 10.5. REFERENCE OF AMENDMENTS. Certificates authenticated,
executed on behalf of the Holders and delivered after the execution of any
amendment pursuant to this Section may, and shall if required by the Collateral
Agent or the

                                      35

<Page>

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

any right, power or remedy hereunder shall operate as a waiver thereof; nor

Intermediary or any of their respective agents of any right, power or remedy
hereunder preclude any other or further exercise thereof or the exercise of any
other right, power or remedy. The remedies herein are cumulative and are not
