as the case may be, on such record date, and no other Holders, shall be entitled
to take the relevant action with respect to the Income PRIDES or the Growth

such record date; provided that no such action shall be effective hereunder

paragraph shall be construed to prevent the Company from setting a new record
date for any action for which a record date has previously been set pursuant to
this paragraph (whereupon the record date previously set shall automatically and
with no action by any Person be cancelled and of no effect), and nothing 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

proposed action by Holders and the applicable Expiration Date to be given to the

the Agent in writing, and to each Holder of Securities in the manner set forth
in Section 1.6, on or prior to the existing Expiration Date. If an Expiration
Date is not designated with respect to any record date set pursuant to this
Section, the Company shall be deemed to have initially designated the 180th day
after such record date as the Expiration Date with respect thereto, subject to
its right to change the Expiration Date as provided in this paragraph.
Notwithstanding the foregoing, no Expiration Date shall be later than the 180th
day after the applicable record date.

of any other cause it shall be impracticable to give such notice by mail, then
such notification as shall be made with the approval of the Agent shall

Section 3.3.  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
Agent for authentication, execution on behalf of the Holders and delivery,
together with its Issuer Order for authentication of such Certificates, and the
Agent in accordance with such Issuer Order shall authenticate, execute on behalf
of the Holders and deliver such Certificates.

      The Certificates shall be executed on behalf of the Company by the
Chairman of the Board, the Chief Executive Officer, the President, the Chief
Operating Officer, the Chief Financial Officer, the General Counsel, the
Secretary or any Vice President (or other officer performing similar functions)
of the Company and delivered to the Agent. 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 Agent, as such Holder's attorney-in-fact. Such
signature by an authorized signatory of the Agent shall be conclusive evidence
that the Holder of such Certificate has entered into the Purchase Contracts
evidenced by such Certificate.

      Each Certificate shall be dated the date of its authentication.

                                       18

<Page>

      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 Agent by manual signature, and such
certificate upon any Certificate shall be conclusive evidence, and the only
evidence, that such Certificate has been duly authenticated and delivered
hereunder.

Section 3.4.  TEMPORARY CERTIFICATES.

      Pending the preparation of definitive Certificates, the Company shall
execute and deliver to the Agent, and the Agent shall authenticate, execute on
behalf of the Holders, and deliver, in lieu of such definitive Certificates,
temporary Certificates which are in substantially the form set forth in Exhibit
A or Exhibit B hereto, as the case may be, with such letters, numbers or other
marks of identification or designation and such legends or endorsements printed,
lithographed or engraved thereon as may be required by the rules of any
securities exchange on which the Income PRIDES or Growth PRIDES 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 Agent, and the Agent
shall authenticate, execute on behalf of the Holder, and deliver in exchange
therefor, one or more definitive Certificates of like tenor and denominations
and evidencing a like number of Income PRIDES or Growth PRIDES, as the case may
be, as the temporary Certificate or Certificates so surrendered. Until so
exchanged, the temporary Certificates shall in all respects evidence the same
benefits and the same obligations with respect to the Income PRIDES or Growth
PRIDES, as the case may be, evidenced thereby as definitive Certificates.

Section 3.5.  REGISTRATION; REGISTRATION OF TRANSFER AND EXCHANGE.

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

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

                                       19

<Page>

      At the option of the Holder, Certificates may be exchanged for other
Certificates, of any authorized denominations and evidencing a like number of
Income PRIDES or Growth PRIDES, as the case may be, upon surrender of the
Certificates to be exchanged at the Corporate Trust Office. Whenever any
Certificates are so surrendered for exchange, the Company shall execute and
deliver to the Agent, and the Agent shall authenticate, execute on behalf of the
Holder, and deliver the Certificates which the Holder making the exchange is
entitled to receive.

      All Certificates issued upon any registration of transfer or exchange of a
Certificate shall evidence the ownership of the same number of Income PRIDES or
Growth PRIDES, as the case may be, and be entitled to the same benefits and
subject to the same obligations, under this Agreement as the Income PRIDES or
Growth PRIDES, 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
for exchange shall (if so required by the Agent) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Agent duly executed, by the Holder thereof or its attorney duly
authorized in writing.

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

      Notwithstanding the foregoing, the Company shall not be obligated to
execute and deliver to the Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder and deliver any Certificate
presented or surrendered for registration of transfer or for exchange on or
after the Business Day immediately preceding the earlier of the 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 Agent shall (i) if the Purchase Contract Settlement Date
has occurred, deliver the number of shares of Common Stock issuable in respect
of the Purchase Contracts forming a part of the Securities evidenced by such
Certificate, (ii) in the case of Income PRIDES, if a Termination Event shall
have occurred prior to the Purchase Contract Settlement Date, transfer the
aggregate Stated Amount of the Senior Notes evidenced thereby or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, as the case may be, or
(iii) in the case of Growth PRIDES, if a Termination Event shall have occurred
prior to the Purchase Contract Settlement Date, transfer the Treasury Securities
evidenced thereby, in each case subject to the applicable conditions and in
accordance with the applicable provisions of Article Five hereof.

Section 3.6.  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
by, or on behalf of, the Company. Such Global Certificate 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

                                       20

<Page>

will receive a definitive Certificate representing such Beneficial Owner's
interest in such Global Certificate, except as provided in Section 3.9. The
Agent shall enter into an agreement with the Depositary if so requested by
the Company. Unless and until definitive, fully registered Certificates have
been issued to Beneficial Owners pursuant to Section 3.9:

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

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

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

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

Section 3.7.      NOTICES TO HOLDERS.

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

Section 3.8.      APPOINTMENT OF SUCCESSOR CLEARING AGENCY.

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

Section 3.9.      DEFINITIVE CERTIFICATES.

      If (i) a Clearing Agency elects to discontinue its services as securities
depositary with respect to the Securities and a successor Clearing Agency is not
appointed within 90 days after such discontinuance pursuant to Section 3.8, (ii)
the Company elects to terminate the book-entry system through the Clearing
Agency with respect to the Securities, or (iii) there shall have occurred and be
continuing a default by the Company in respect of its obligations under one or
more Purchase Contracts, then upon surrender of the Global Certificates
representing the Book-Entry Interests with respect to the Securities by the
Clearing Agency, accompanied by registration instructions, the Company shall
cause definitive Certificates to be delivered to Beneficial Owners in accordance
with the instructions of the Clearing Agency. 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.

                                     21

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

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

      If there shall be delivered to the Company and the Agent (i) evidence to
their satisfaction of the destruction, loss or theft of any Certificate, and
(ii) such security or indemnity at the cost of the Holder as may be required by
them to hold each of them and any agent of any of them harmless, then, in the
absence of notice to the Company or the Agent that such Certificate has been
acquired by a bona fide purchaser, the Company shall execute and deliver to the
Agent, and the Agent shall authenticate, execute on behalf of the Holder, and
deliver to the Holder, in lieu of any such destroyed, lost or stolen
Certificate, a new Certificate, evidencing the same number of Income PRIDES or
Growth PRIDES, 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 Agent, and the Agent shall not be obligated to
authenticate, execute on behalf of the Holder, and deliver to the Holder, a
Certificate on or after the Business Day immediately preceding the earlier of
the 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 Agent shall (i) if the Purchase
Contract Settlement Date has occurred, deliver the number of 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 Termination Event shall
have occurred prior to the Purchase Contract Settlement Date, transfer the
Senior Notes, or the Applicable Ownership Interest of the Treasury Portfolio, as
the case may be, or the Treasury Securities, as the case may be, evidenced
thereby, in each case subject to the applicable conditions and in accordance
with the applicable provisions of Article Five hereof.

      Upon the issuance of any new Certificate under this Section, the Company
and the Agent may require the payment by the Holder of a sum sufficient to cover
any tax or other governmental charge that may be imposed in relation thereto and
any other expenses (including the fees and expenses of the 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 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 Agent, and any agent of the Company or the Agent, may treat
the Person in whose name such Certificate is registered as the owner of the
Income PRIDES or Growth PRIDES evidenced thereby, for the purpose of receiving
interest on the Senior Notes or on the maturing interest strips of the Treasury
Portfolio, as applicable, performance of the Purchase Contracts and for all
other purposes whatsoever, whether or not interest on the Senior Notes shall be
overdue and notwithstanding any notice to the contrary, and neither the Company
nor the Agent, nor any agent of the Company or the Agent, shall be affected by
notice to the contrary.

      Notwithstanding the foregoing, with respect to any Global Certificate,
nothing herein shall prevent the Company, the Agent or any agent of the Company
or the Agent, from giving effect to any written certification, proxy or other
authorization furnished by any Clearing Agency (or its nominee), as a Holder,
with respect to such Global Certificate or impair, as between such Clearing
Agency and owners of beneficial interests in such Global Certificate, the
operation of customary practices governing the exercise of rights of such
Clearing Agency (or its nominee) as Holder of such Global Certificate.

Section 3.12.     CANCELLATION.

      All Certificates surrendered for delivery of Common Stock on or after the
Purchase Contract Settlement Date, upon the transfer of Senior Notes or the
Applicable Ownership Interest of the Treasury Portfolio, as the case may be, 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 a transfer
or exchange of a Security, or a Collateral Substitution or the re-establishment
of an Income PRIDES shall, if surrendered to any Person other than the Agent, be
delivered to the Agent and, if not already cancelled, shall be promptly
cancelled by it. The Company may at any time deliver to the Agent for
cancellation any Certificates previously authenticated, executed and delivered
hereunder which the Company may have acquired in any manner whatsoever, and all
Certificates so delivered shall, upon Issuer Order, be promptly cancelled by the
Agent. No Certificates shall be authenticated, executed on behalf of the Holder
and delivered in lieu of or in exchange for any Certificates cancelled as
provided in this Section, except as expressly permitted by this Agreement. All
cancelled Certificates held by the Agent shall be disposed of by the Agent in
accordance with its customary practices or upon written request be returned to
the Company.

      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 Agent
cancelled or for cancellation.

Section 3.13.     ESTABLISHMENT OF GROWTH PRIDES.

      A Holder may separate the Senior Notes or the appropriate Applicable
Ownership Interest of the Treasury Portfolio, as applicable, from the related
Purchase Contracts in respect of an Income PRIDES by substituting for such
Senior Notes or the appropriate Applicable Ownership Interest of the Treasury
Portfolio, as the case may be, Treasury Securities in an

                                     23

<Page>

aggregate principal amount of such Senior Notes or the appropriate Applicable
Ownership Interest (as specified in clause (A) of the definition of such
term) of the Treasury Portfolio, as applicable (a "Collateral Substitution"),
at any time from and after the date of this Agreement and on or prior to the
fifth Business Day immediately preceding the Purchase Contract Settlement
Date in the case of the Senior Notes and on or prior to the second Business
Day immediately preceding the Purchase Contract Settlement Date in the case
of the appropriate Applicable Ownership Interest of the Treasury Portfolio,
in each case by (a) depositing with the Collateral Agent Treasury Securities
having an aggregate principal amount at maturity equal to the aggregate
principal amount of the Senior Notes comprising part of such Income PRIDES or
the appropriate Applicable Ownership Interest (as specified in clause (A) of
the definition of such term) of the Treasury Portfolio comprising part of
such Income PRIDES, as the case may be, and (b) transferring the related
Income PRIDES to the Agent accompanied by a notice to the Agent,
substantially in the form of Exhibit D hereto, stating that the Holder has
transferred the relevant amount of Treasury Securities to the Collateral
Agent and requesting that the Agent instruct the Collateral Agent to release
the Senior Notes or the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, underlying such Income PRIDES,
whereupon the Agent shall promptly give such instruction to the Collateral
Agent, substantially in the form of Exhibit C hereto. Upon receipt of the
Treasury Securities described in clause (a) above and the instruction
described in clause (b) above, in accordance with the terms of the Pledge
Agreement, the Collateral Agent will release to the Agent, on behalf of the
Holder, Senior Notes or the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, having the appropriate aggregate
principal amount in the case of such Senior Notes or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, as the case may be,
from the Pledge, free and clear of the Company's security interest therein,
and upon receipt thereof the Agent shall promptly:

            (i) cancel the related Income PRIDES;

            (ii) transfer the Senior Notes or the appropriate Applicable
Ownership Interest of the Treasury Portfolio, as the case may be, to the
Holder; and

            (iii) authenticate, execute on behalf of such Holder and deliver a
Growth PRIDES Certificate executed by the Company in accordance with Section 3.3
evidencing the same number of Purchase Contracts as were evidenced by the
cancelled Income PRIDES.

      Holders who elect to separate the Senior Notes or the appropriate
Applicable Ownership Interest of the Treasury Portfolio, as the case may be,
from the related Purchase Contract and to substitute Treasury Securities for
such Senior Notes or the appropriate Applicable Ownership Interest of the
Treasury Portfolio, 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 (i) only in integral multiples
of 40 Income PRIDES if Treasury Securities are being substituted for by the
Senior Notes, or (ii) only in integral multiples of 8,000 Income PRIDES if
Treasury Securities are being substituted for appropriate Applicable Ownership
Interest of the Treasury Portfolio.

                                     24

<Page>

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

      Except as provided in this Section 3.13, for so long as the Purchase
Contract underlying an Income PRIDES remains in effect, such Income PRIDES shall
not be separable into its constituent parts, and the rights and obligations of
the Holder in respect of the Senior Notes or the appropriate Applicable
Ownership Interest of the Treasury Portfolio, as the case may be, and Purchase
Contract comprising such Income PRIDES may be acquired, and may be transferred
and exchanged, only as an Income PRIDES.

Section 3.14.     REESTABLISHMENT OF INCOME PRIDES.

      A Holder of a Growth PRIDES may create or recreate Income PRIDES at any
time (i) on or prior to the fifth Business Day immediately preceding the
Purchase Contract Settlement Date, if a Tax Event Redemption or a Successful
Initial Remarketing has not occurred, and (ii) on or prior to the second
Business Day immediately preceding the Purchase Contract Settlement Date, if a
Tax Event Redemption or a Successful Initial Remarketing has occurred and an
Applicable Ownership Interest in the Treasury Portfolio has become a component
of the Income PRIDES, in each case by (a) depositing with the Collateral Agent
Senior Notes or the appropriate Applicable Ownership Interest of the Treasury
Portfolio, as the case may be, having an aggregate principal amount in the case
of the Senior Notes, or an appropriate Applicable Ownership Interest (as defined
in clause (A) of the definition of such term) of the Treasury Portfolio, as the
case may be, equal to the aggregate principal amount of the Treasury Securities
comprising part of the Growth PRIDES and (b) transferring the related Growth
PRIDES to the Agent accompanied by a notice to the Agent, substantially in the
form of Exhibit D hereto, stating that the Holder has transferred the relevant
amount of Senior Notes or the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, to the Collateral Agent and requesting
that the Agent instruct the Collateral Agent to release the Treasury Securities
underlying such Growth PRIDES, whereupon the Agent shall promptly give such
instruction to the Collateral Agent, substantially in the form of Exhibit C
hereto. Upon receipt of the Senior Notes or the appropriate Applicable Ownership
Interest of the Treasury Portfolio, as the case may be, described in clause (a)
above and the instruction described in clause (b) above, in accordance with the
terms of the Pledge Agreement, the Collateral Agent will release to the Agent,
on behalf of the Holder, the Treasury Securities having a corresponding
aggregate principal amount from the Pledge, free and clear of the Company's
security interest therein, and upon receipt thereof the Agent shall promptly:

            (i) cancel the related Growth PRIDES;

                                     25

<Page>

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

            (iii) authenticate, execute on behalf of such Holder and deliver an
Income PRIDES Certificate executed by the Company in accordance with Section 3.3
evidencing the same number of Purchase Contracts as were evidenced by the
cancelled Growth PRIDES.

      Holders of Growth PRIDES may reestablish Income PRIDES in integral
multiples of 40 Growth PRIDES for the same multiple of 40 Income PRIDES if a Tax
Event Redemption or a Successful Initial Remarketing has not occurred, and in
integral multiples of 8,000 Growth PRIDES for 8,000 Income PRIDES if a Tax Event
Redemption or a Successful Initial Remarketing has occurred.

      In the event a Holder re-establishing Income PRIDES pursuant to this
Section 3.14 fails to effect a book-entry transfer of the Growth PRIDES or fails
to deliver a Growth PRIDES Certificate(s) to the Agent after depositing Senior
Notes or the appropriate Applicable Ownership Interest of the Treasury
Portfolio, as the case may be, with the Collateral Agent, the Treasury
Securities constituting a part of such Growth PRIDES shall be held in the name
of the Agent or its nominee in trust for the benefit of such Holder, until such
Growth PRIDES are so transferred or the Growth PRIDES Certificate is so
delivered, as the case may be, or, with respect to a Growth PRIDES Certificate,
such Holder provides evidence satisfactory to the Company and the Agent that
such Growth PRIDES Certificate has been destroyed, lost or stolen, together with
any indemnity that may be required by the Agent and the Company.

      Except as provided in this Section 3.14, for so long as the Purchase
Contract underlying a Growth PRIDES remains in effect, such Growth PRIDES shall
not be separable into its constituent parts and the rights and obligations of
the Holder of such Growth PRIDES in respect of the Treasury Security and
Purchase Contract comprising such Growth PRIDES may be acquired, and may be
transferred and exchanged, only as a Growth PRIDES.

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

      Upon the occurrence of a Termination Event and the transfer to the Agent
of the Senior Notes, the appropriate Applicable Ownership Interest of the
Treasury Portfolio or the Treasury Securities, as the case may be, underlying
the Income PRIDES and the Growth PRIDES pursuant to the terms of the Pledge
Agreement, the Agent shall request transfer instructions with respect to such
Senior Notes or the appropriate Applicable Ownership Interest of the Treasury
Portfolio or Treasury Securities, as the case may be, from each Holder by
written request mailed to such Holder at its address as it appears in the Income
PRIDES Register or the Growth PRIDES Register, as the case may be. Upon
book-entry transfer of the Income PRIDES or Growth PRIDES or delivery of an
Income PRIDES Certificate or a Growth PRIDES Certificate to the Agent with such
transfer instructions, the Agent shall transfer the Senior Notes, the Applicable
Ownership Interest of the Treasury Portfolio or Treasury Securities, as the case
may be, underlying such Income PRIDES or Growth PRIDES, as the case may be, to
such Holder by book-entry transfer, or other appropriate procedures, in
accordance with such instructions; provided, however, that, to the extent that a
Holder of Income PRIDES or Growth PRIDES would otherwise be entitled to receive
less than $1,000 principal amount at maturity of the

                                     26

Treasury Portfolio or the Treasury Securities, the Agent shall dispose of
such securities for cash, and transfer the appropriate amount of such cash to
such Holder in accordance with such Holder's instructions. In the event a
Holder of Income PRIDES or Growth PRIDES fails to effect such transfer or
delivery, the Senior Notes, the appropriate Applicable Ownership Interest of
the Treasury Portfolio or Treasury Securities, as the case may be, underlying
such Income PRIDES or Growth PRIDES, as the case may be, and any
distributions thereon, shall be held in the name of the Agent or its nominee
in trust for the benefit of such Holder, until such Income PRIDES or Growth
PRIDES are transferred or the Income PRIDES Certificate or Growth PRIDES
Certificate is surrendered or such Holder provides satisfactory evidence that
such Income PRIDES Certificate or Growth PRIDES Certificate has been
destroyed, lost or stolen, together with any indemnity that may be required
by the Agent and the Company.

Section 3.16.     CUSIP NUMBERS.

      The Company in issuing the Securities may use CUSIP numbers (if then
generally in use), and, if so, the Agent shall use CUSIP numbers in notices as a
convenience to Holders; PROVIDED that any such notice may state that no
representation is made as to the correctness of such numbers either as printed
on the Securities or as contained in any notice of a redemption and that
reliance may be placed only on the other identification numbers printed on the
Securities, and any such redemption shall not be affected by any defect in or
omission of such numbers. The Company will promptly notify the Agent of any
change in the CUSIP numbers.

                                THE SENIOR NOTES

Section 4.1.      INTEREST AND OTHER PAYMENTS; RIGHTS TO PAYMENTS PRESERVED;
RATE RESET; NOTICE

      Interest on any Senior Note or on the appropriate Applicable Ownership
Interest in the Treasury Portfolio, as the case may be, which is made on any
Payment Date shall, subject to receipt thereof by the Agent from the Collateral
Agent as provided by the terms of the Pledge Agreement, be paid to the Person in
whose name the Income PRIDES Certificate (or one or more Predecessor Income
PRIDES Certificates) of which such Senior Note or the appropriate Applicable
Ownership Interest of the Treasury Portfolio, as the case may be, is a part is
registered at the close of business on the Record Date for such Payment Date.

      Each Income PRIDES Certificate evidencing Senior Notes delivered under
this Agreement upon registration of transfer of or in exchange for or in lieu of
any other Income PRIDES Certificate shall carry the rights to accrued and unpaid
interest, and other amounts that are to accrue, which were or will be carried by
the Senior Notes underlying such other Income PRIDES Certificate.

      In the case of any Income PRIDES with respect to which Cash Settlement of
the underlying Purchase Contract is effected on the Business Day immediately
preceding the Purchase Contract Settlement Date pursuant to prior notice, or
with respect to which Early Settlement of the underlying Purchase Contract is
effected on an Early Settlement Date, or with respect to which a Collateral
Substitution is effected, in each case on a date that is after any Record Date
and on or prior to the next succeeding Payment Date, interest on the Senior
Notes or

                                     27

<Page>

distributions on the appropriate Applicable Ownership Interest of the
Treasury Portfolio, as the case may be, underlying such Income PRIDES
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
Agent, be payable to the Person in whose name the Income PRIDES Certificate
(or one or more Predecessor 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 Income PRIDES with respect
to which Cash Settlement or Early Settlement of the underlying Purchase
Contract is effected on the Business Day immediately preceding the Purchase
Contract Settlement Date or an Early Settlement Date, as the case may be, or
with respect to which a Collateral Substitution has been effected,
distributions on the related Senior Notes or on 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 or Early
Settlement Date shall not be payable hereunder to the Holder of such Income
PRIDES; provided, however, that to the extent that such Holder continues to
hold the separated Senior Notes that formerly comprised a part of such
Holder's Income PRIDES, such Holder shall be entitled to receive any payments
made on such separated Senior Notes.

      The applicable Coupon Rate on the Senior Notes on and after August 17,
2004 will be reset on the Initial Remarketing Date to the applicable Reset Rate
(such Reset Rate to be in effect on and after August 17, 2004), except in the
event of a Failed Initial Remarketing. In the event of a Failed Initial
Remarketing, the applicable Coupon Rate on the Senior Notes outstanding on and
after the Purchase Contract Settlement Date will be reset on the Secondary
Remarketing Date to the applicable Reset Rate (such Reset Rate to be in effect
on and after the Purchase Contract Settlement Date). On the applicable Reset
Announcement Date, the Reset Spread and the Two-Year Benchmark Treasury or Two
and One-Quarter Benchmark Treasury, as applicable, to be used to determine the
Reset Rate will be announced by the Company. On the Business Day immediately
following the Reset Announcement Date, the Holders of Senior Notes will be
notified of such Reset Spread and Two-Year Benchmark Treasury or Two and
One-Quarter Benchmark Treasury, as applicable, by the Company. Such notice shall
be sufficiently given to Holders of Senior Notes if published in an Authorized
Newspaper in The City of New York.

      Not less than 7 calendar days nor more than 15 calendar days prior to the
Reset Announcement Date, the Company will notify DTC or its nominee (or any
successor Clearing Agency or its nominee) by first-class mail, postage prepaid,
to notify the Beneficial Owners or Clearing Agency Participants holding Income
PRIDES or Growth PRIDES, of such Reset Announcement Date and the procedures to
be followed by such Holders of Income PRIDES who intend to settle their
obligation under the Purchase Contract with separate cash on the Purchase
Contract Settlement Date.

Section 4.2.      NOTICE AND VOTING.

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

                                     28

<Page>

thereafter, mail to the Holders of Income PRIDES a notice
(a) containing such information as is contained in the notice or solicitation,
(b) stating that each Holder on the record date set by the Agent therefor
(which, to the extent possible, shall be the same date as the record date for
determining the holders of Senior Notes entitled to vote) shall be entitled to
instruct the Agent as to the exercise of the voting rights pertaining to the
Senior Notes underlying their Income PRIDES and (c) stating the manner in which
such instructions may be given. Upon the written request of the Holders of
Income PRIDES on such record date, the Agent shall endeavor insofar as
practicable to vote or cause to be voted, in accordance with the instructions
set forth in such requests, the maximum number of Senior Notes as to which any
particular voting instructions are received. In the absence of specific
instructions from the Holder of an Income PRIDES, the Agent shall abstain from
voting the Senior Note underlying such Income PRIDES. The Company hereby agrees,
if applicable, to solicit Holders of Income PRIDES to timely instruct the Agent
in order to enable the Agent to vote such Senior Notes.

Section 4.3.      TAX EVENT REDEMPTION.

      Upon the occurrence of a Tax Event Redemption prior to August 17, 2004, or
in the event of a Failed Initial Remarketing, prior to the Purchase Contract
Settlement Date, pursuant to the terms of the Pledge Agreement, the Collateral
Agent will apply, out of the aggregate Redemption Price for the Senior Notes
that are components of Income PRIDES, an amount equal to the aggregate
Redemption Amount for the Senior Notes that are components of Income PRIDES to
purchase on behalf of the Holders of Income PRIDES the Treasury Portfolio and
promptly remit the remaining portion of such Redemption Price to the Agent for
payment to the Holders of such Income PRIDES. The Treasury Portfolio will be
substituted for the pledged Senior Notes, 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 an Income PRIDES to purchase the Common Stock of
the Company under the Purchase Contract constituting a part of such Income
PRIDES. Following the occurrence of a Tax Event Redemption prior to August 17,
2004, or, in the event of a Failed Initial Remarketing, prior to the Purchase
Contract Settlement Date, the Holders of Income PRIDES and the Collateral Agent
shall have such security interests, rights and obligations with respect to the
Treasury Portfolio as the Holder of Income PRIDES and the Collateral Agent had
in respect of the Senior Notes, as the case may be, subject to the Pledge
thereof as provided in the Pledge Agreement, and any reference herein or in the
Certificates to the Senior Note shall be deemed to be a reference to such
Treasury Portfolio and any reference herein or in the Certificates to interest
on the Senior Notes shall be deemed to be a reference to corresponding
distributions on the Treasury Portfolio. The Company may cause to be made in any
Income PRIDES Certificates thereafter to be issued such change in phraseology
and form (but not in substance) as may be appropriate to reflect the
substitution of the Treasury Portfolio for Senior Notes as collateral.

                                    ARTICLE V
                             THE PURCHASE CONTRACTS

Section 5.1.      PURCHASE OF COMMON STOCK.

      Each Purchase Contract shall, unless an Early Settlement has occurred in
accordance with Section 5.8 hereof, obligate the Holder of the related Security
to purchase, and the Company to

                                     29
<Page>

sell, on the Purchase Contract Settlement Date at a price equal to the Stated
Amount (the "Purchase Price"), a number of newly issued shares of Common
Stock equal to the Settlement Rate unless, on or 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. The
"Settlement Rate" is equal to (a) if the Applicable Market Value (as defined
below) is equal to or greater than $84.0650 (the "Threshold Appreciation
Price"), 0.2974 shares of Common Stock per Purchase Contract, (b) if the
Applicable Market Value is less than the Threshold Appreciation Price, but is
greater than $73.10 (the "Threshold Depreciation Price"), the number of
shares of Common Stock per Purchase Contract equal to the Stated Amount
divided by the Applicable Market Value and (c) if the Applicable Market Value
is less than or equal to Threshold Depreciation Price, 0.3420 shares of
Common Stock per Purchase Contract, in each case subject to adjustment as
provided in Section 5.5 (and in each case rounded upward or downward to the
nearest 1/10,000th of a share). As provided in Section 5.9, no fractional
shares of Common Stock will be issued upon settlement of Purchase Contracts.

      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" of the Common Stock on any date of determination means
the closing sale price (or, if no closing price is reported, the last reported
sale price) of the Common Stock on the New York Stock Exchange (the "NYSE") on
such date or, if the Common Stock is not listed for trading on the NYSE on any
such date, as reported in the composite transactions for the principal United
States securities exchange on which the Common Stock is so listed, or if the
Common Stock is not so listed on a United States national or regional securities
exchange, as reported by The Nasdaq Stock Market, or, if the Common Stock is not
so reported, the last quoted bid price for the Common Stock in the
over-the-counter market as reported by the National Quotation Bureau or similar
organization, or, if such bid price is not available, the market value of the
Common Stock on such date as of 4:00 p.m., New York City time, as determined by
a nationally recognized independent investment banking firm retained for this
purpose by the Company.

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

      Each Holder of an Income PRIDES or a Growth PRIDES, by its acceptance
thereof, irrevocably authorizes the Agent to enter into and perform the related
Purchase Contract on its behalf as its attorney-in-fact (including the execution
of Certificates on behalf of such Holder), agrees to be bound by the terms and
provisions thereof, covenants and agrees to perform its obligations under such
Purchase Contracts, and consents to the provisions hereof, irrevocably
authorizes the Agent as its attorney-in-fact to enter into and perform the
Pledge Agreement on its behalf as its attorney-in-fact, and consents to and
agrees to be bound by the Pledge of the Senior Notes 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

                                       30

<Page>

enforced without regard to any other rights or obligations. Each Holder of an
Income PRIDES or a Growth PRIDES, by its acceptance thereof, further covenants
and agrees, that, to the extent and in the manner provided in the Pledge
Agreement, but subject to the terms thereof, payments in respect of the Stated
Amount of the Senior Notes or the Proceeds of the Treasury Securities, the
Senior Notes or the Treasury Portfolio, as applicable, 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.

      Upon registration of transfer of a Certificate, the transferee shall be
bound (without the necessity of any other action on the part of such
transferee), under the terms of this Agreement, the Purchase Contracts
underlying such Certificate and the Pledge Agreement and the transferor shall be
released from the obligations under this Agreement, the Purchase Contracts
underlying the Certificates so transferred and the Pledge Agreement. The Company
covenants and agrees, and each Holder of a Certificate, by its acceptance
thereof, likewise covenants and agrees, to be bound by the provisions of this
paragraph.

      The Agent shall have no responsibility whatsoever for calculating or
determining any amounts under this Section or elsewhere in this Agreement, and
shall have no liability whatsoever for any errors with respect to such
calculations or amounts.

Section 5.2.  INITIAL REMARKETING.

      Unless a Tax Event Redemption has occurred, the Company shall engage a
nationally recognized investment bank (the "Remarketing Agent") pursuant to the
Remarketing Agreement to sell the Senior Notes (the "Initial Remarketing") on
the third Business Day immediately preceding August 17, 2004 (the "Initial
Remarketing Date"). In order to facilitate the remarketing, the Agent shall
notify, by 10:00 a.m., New York City time, on the Business Day immediately
preceding the Initial Remarketing Date, the Remarketing Agent of the aggregate
principal amount of Senior Notes to be remarketed. Concurrently, the Collateral
Agent, pursuant to the terms of the Pledge Agreement, will present for
remarketing such Senior Notes to the Remarketing Agent. Upon receipt of such
notice from the Agent and such Senior Notes from the Collateral Agent, the
Remarketing Agent will, on the Initial Remarketing Date, use its reasonable
efforts to remarket such Senior Notes on such date at a price of approximately
100.5% (but not less than 100%) of the Treasury Portfolio Purchase Price. If the
Remarketing Agent is able to remarket the Senior Notes at a price equal to or
greater than 100% of the Treasury Portfolio Purchase Price (a "Successful
Initial Remarketing"), the portion of the proceeds from such Successful Initial
Remarketing equal to the Treasury Portfolio Purchase Price will be applied to
purchase the Treasury Portfolio. In addition, the Remarketing Agent may deduct
as a remarketing fee ("Remarketing Fee") an amount equal to 25 basis points
(0.25%) of the Treasury Portfolio Purchase Price from any amount of such
proceeds in excess of the Treasury Portfolio Purchase Price. Any proceeds in
excess of those required to pay the Treasury Portfolio Purchase Price and the
Remarketing Fee will be remitted to the Agent for payment to the Holders of the
related Income PRIDES. Income PRIDES Holders whose Senior Notes are so
remarketed will not otherwise be responsible for the payment of any Remarketing
Fee in connection therewith. The Treasury Portfolio will be substituted for the
Senior Notes of Holders of Income PRIDES and will be pledged to the Collateral
Agent to secure the Income PRIDES Holders' obligation to

                                       31

<Page>

pay the Purchase Price for the Common Stock under the related Purchase
Contracts on the Purchase Contract Settlement Date. Following the occurrence
of a Successful Initial Remarketing, the Holders of Income PRIDES and the
Collateral Agent shall have such security interests, rights and obligations
with respect to the Treasury Portfolio as the Holder of Income PRIDES and the
Collateral Agent had in respect of the Senior Notes, as the case may be,
subject to the Pledge thereof as provided in the Pledge Agreement, and any
reference herein or in the Certificates to the Senior Notes shall be deemed
to be a reference to such Treasury Portfolio and any reference herein or in
the Certificates to interest on the Senior Notes shall be deemed to be a
reference to corresponding distributions on the Treasury Portfolio. The
Company may cause to be made in any Income PRIDES Certificates thereafter to
be issued such change in phraseology and form (but not in substance) as may
be appropriate to reflect the substitution of the Treasury Portfolio for
Senior Notes as collateral.

      If, in spite of using its reasonable efforts, the Remarketing Agent cannot
remarket the related Senior Notes (other than to the Company) of such Holders of
Income PRIDES at a price not less than 100% of the Treasury Portfolio Purchase
Price, the remarketing will be deemed to have failed (a "Failed Initial
Remarketing"). The Company will cause a notice of a Failed Initial Remarketing
to be published on the second Business Day immediately preceding August 17, 2004
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.

Section 5.3.  PAYMENT OF PURCHASE PRICE.

      (a) (i) Unless a Tax Event Redemption has occurred or a Holder settles the
underlying Purchase Contract through the early delivery of cash to the Agent in
the manner described in Section 5.8, each Holder of an Income PRIDES must notify
the Agent by use of a notice in substantially the form of Exhibit E hereto of
its intention to pay in cash ("Cash Settlement") the Purchase Price for the
Common Stock to be purchased pursuant to a Purchase Contract. Such notice shall
be made on or prior to 5:00 p.m., New York City time, on the fifth Business Day
immediately preceding the Purchase Contract Settlement Date. The Agent shall
promptly notify the Collateral Agent of the receipt of such a notice from a
Holder intending to make a Cash Settlement.

            (ii) A Holder of an Income PRIDES who has so notified the Agent of
its intention to make a Cash Settlement is required to pay the Purchase Price to
the Collateral Agent 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 Company.
Any cash received by the Collateral Agent will be invested promptly by the
Collateral Agent 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 Collateral Agent in respect of the investment earnings from the
investment in such Permitted Investments will be distributed to the Agent when
received for payment to the Holder.

                                       32

<Page>

            (iii) If a Holder of an Income PRIDES fails to notify the Agent of
its intention to make a Cash Settlement in accordance with paragraph (a)(i)
above, such failure shall constitute an event of default and the Holder shall be
deemed to have consented to the disposition of the pledged Senior Notes pursuant
to the remarketing as described in paragraph (b) below. If a Holder of an Income
PRIDES does notify the Agent as provided in paragraph (a)(i) above of its
intention to pay the Purchase Price in cash, but fails to make such payment as
required by paragraph (a)(ii) above, such failure shall also constitute a
default; however, the Senior Notes of such a Holder will not be remarketed but
instead the Collateral Agent, for the benefit of the Company, will exercise its
rights as a secured party with respect to such Senior Notes, including those
rights specified in paragraph (c) below.

      (b) Unless a Tax Event Redemption or a Successful Initial Remarketing has
occurred, the Senior Notes of Income PRIDES Holders who have not notified the
Agent of their intention to effect a Cash Settlement as provided in paragraph
(a)(i) above will be sold by the Remarketing Agent (the "Secondary Remarketing")
on the third Business Day immediately preceding the Purchase Contract Settlement
Date (the "Secondary Remarketing Date"). The Agent shall notify, by 10:00 a.m.,
New York City time, on the Business Day immediately preceding the Secondary
Remarketing Date, the Remarketing Agent of the aggregate principal amount of
Senior Notes to be remarketed. Concurrently, the Collateral Agent, pursuant to
the terms of the Pledge Agreement, will present for remarketing such Senior
Notes to the Remarketing Agent. Upon receipt of such notice from the Agent and
such Senior Notes from the Collateral Agent, the Remarketing Agent will, on the
Secondary Remarketing Date, use its reasonable efforts to remarket such Senior
Notes on such date at a price of approximately 100.5% (but not less than 100%)
of the aggregate principal amount of such Senior Notes. If the Remarketing Agent
is able to remarket the Senior Notes at a price equal to or greater than 100% of
the aggregate principal amount of Senior Notes (a "Successful Secondary
Remarketing"), the Remarketing Agent will remit the entire amount of the
proceeds from such Successful Secondary Remarketing to the Collateral Agent;
provided, however, that the Remarketing Agent may deduct as the Remarketing Fee
an amount equal to 25 basis points (0.25%) of the aggregate principal amount of
the remarketed Senior Notes from any amount of the proceeds of a Successful
Secondary Remarketing in excess of the aggregate principal amount of the
remarketed Senior Notes. The portion of the proceeds equal to the aggregate
principal amount of Senior Notes will automatically be applied by the Collateral
Agent, in accordance with the Pledge Agreement, to satisfy in full such Income
PRIDES holders' obligations to pay the Purchase Price for the Common Stock under
the related Purchase Contracts on the Purchase Contract Settlement Date. Any
proceeds in excess of those required to pay the Purchase Price and the
Remarketing Fee will be remitted to the Agent for payment to the Holders of the
related Income PRIDES. Income PRIDES Holders whose Senior Notes are so
remarketed will not otherwise be responsible for the payment of any Remarketing
Fee in connection therewith. If, in spite of using its reasonable efforts, the
Remarketing Agent cannot remarket the related Senior Notes (other than to the
Company) of such Holders of Income PRIDES at a price not less than 100% of the
aggregate principal amount of the Senior Notes, the remarketing will be deemed
to have failed (a "Failed Secondary Remarketing") and in accordance with the
terms of the Pledge Agreement the Collateral Agent for the benefit of the
Company will exercise its rights as a secured party with respect to such Senior
Notes, including those actions specified in paragraph (c) below. The Company
will cause a notice of such Failed Secondary Remarketing to be published on the
second Business Day immediately preceding the Purchase Contract Settlement Date
in a daily

                                       33

<Page>

newspaper in the English language of general circulation in The City of New
York, which is expected to be The Wall Street Journal.

      (c) With respect to any Senior Notes beneficially owned by Holders who
have elected Cash Settlement but failed to deliver cash as required in (a)(ii)
above, or with respect to Senior Notes which are subject to a Failed Secondary
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 (g) below, may, among other things, (i) retain the Senior
Notes in full satisfaction of the Holders obligations under the Purchase
Contracts or (ii) sell the Senior Notes in one or more public or private sales.

      (d) (i) Unless a Holder of Growth PRIDES settles the underlying Purchase
Contract through the early delivery of cash to the Agent in the manner described
in Section 5.8 or a Tax Event Redemption or a successful Initial Remarketing has
occurred, each Holder of a Growth PRIDES must notify the Agent by use of a
notice in substantially the form of Exhibit E hereto of its intention to pay in
cash the Purchase Price for the Common Stock to be purchased pursuant to a
Purchase Contract on or prior to 5:00 p.m., New York City time, on the second
Business Day immediately preceding the Purchase Contract Settlement Date.

            (ii) A Holder of a Growth PRIDES who has so notified the Agent of
its intention to make a Cash Settlement in accordance with paragraph (d)(i)
above is required to pay the Purchase Price to the Collateral Agent 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 Company. Any cash received
by the Collateral Agent will be invested promptly by the Collateral Agent in
specific Permitted Investments as directed in writing by the Company 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 Collateral Agent in respect of the
investment earnings from the investment in such Permitted Investments will be
distributed to the Agent when received for payment to the Holder.

            (iii) If a Holder of a Growth PRIDES notifies the Agent of its
intention to make a Cash Settlement in accordance with paragraph (d)(i) above,
but fails to make such payment as required by paragraph (d)(ii) above, then upon
the maturity of the Pledged Treasury Securities held by the Collateral Agent on
the Business Day immediately prior to the Purchase Contract Settlement Date, the
principal amount at maturity of the Treasury Securities or the Applicable
Ownership Interest (as defined in clause (A) of the definition of such term) of
the Treasury Portfolio, received by the Collateral Agent will be invested
promptly in specific overnight Permitted Investments as directed in writing by
the Company. On the Purchase Contract Settlement Date, an amount equal to the
Purchase Price will 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 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 will distribute
such excess to the Agent for the benefit of the Holder of the related Growth
PRIDES when received.

                                       34

<Page>

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

      (f) Unless a Holder settles the underlying Purchase Contract through the
early delivery of cash to the Collateral Agent in the manner described herein,
the Company shall not be obligated to issue any Common Stock in respect of a
Purchase Contract or deliver any certificate therefor to the Holder unless it
shall have received payment in full of the Purchase Price for the Common Stock
to be purchased thereunder in the manner herein set forth.

      (g) Upon Cash Settlement of any Purchase Contract, (i) the Collateral
Agent will in accordance with the terms of the Pledge Agreement cause the
Pledged Senior Notes or the Pledged Treasury Securities underlying the relevant
Security to be released from the Pledge by the Collateral Agent free and clear
of any security interest of the Company and transferred to the Agent for
delivery to the Holder thereof or its designee as soon as practicable and (ii)
subject to the receipt thereof from the Collateral Agent, the Agent shall, by
book-entry transfer, or other appropriate procedures, in accordance with
instructions provided by the Holder thereof, transfer such Senior Notes or such
Treasury Securities (or, if no such instructions are given to the Agent by the
Holder, the Agent shall hold such Senior Notes or such Treasury Securities, and
any dividends or distributions thereon, in the name of the Agent or its nominee
in trust for the benefit of such Holder).

      (h) The obligations of the Holders to pay the Purchase Price are
non-recourse obligations and are payable solely out of any Cash Settlement or
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 Collateral disposition and the Purchase Price.

Section 5.4.  ISSUANCE OF COMMON STOCK.

      Unless a Termination Event shall have occurred on or prior to the Purchase
Contract Settlement Date or an Early Settlement shall have occurred, on the
Purchase Contract Settlement Date, upon its receipt of payment in full of the
Purchase Price for the Common Stock purchased by the Holders pursuant to the
foregoing provisions of this Article and subject to Section 5.5(b), the Company
shall issue and deposit with the Agent, for the benefit of the Holders of the
Outstanding Securities, one or more certificates representing the newly issued
shares of Common Stock registered in the name of the Agent (or its nominee) as
custodian for the Holders (such certificates for 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 Agent on or after the Purchase Contract
Settlement Date, together with settlement instructions thereon duly completed
and executed, the Holder of such Certificate shall be entitled to receive in
exchange therefor a certificate representing that number of 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
5.9 and any dividends or distributions with

                                       35

<Page>

respect to such shares constituting part of the Purchase Contract Settlement
Fund, but without any interest thereon, and the Certificate so surrendered
shall forthwith be cancelled. Such shares shall be registered in the name of
the Holder or the Holder's designee as specified in the settlement
instructions provided by the Holder to the Agent. If any shares of Common
Stock issued in respect of a Purchase Contract are to be registered to a
Person other than the Person in whose name the Certificate evidencing such
Purchase Contract is registered, no such registration shall be made unless
the Person requesting such registration has paid any transfer and other taxes
required by reason of such registration in a name other than that of the
registered Holder of 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 5.5.  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 the Common Stock in Common Stock, the Settlement Rate, as 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 the numerator shall be the number of shares of Common Stock outstanding
at the close of business on the date fixed for such determination and the
denominator shall be the sum of such number of shares and the total number of
shares constituting such dividend or other distribution, such 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 the time outstanding shall not include
shares held in the treasury of the Company but shall include any shares issuable
in respect of any scrip certificates issued in lieu of fractions of shares of
Common Stock. The Company will not pay any dividend or make any distribution on
Common Stock held in the treasury of the Company.

           (2) In case the Company shall issue rights, options or warrants to
all holders of its Common Stock (not being available on an equivalent basis to
Holders of the Securities upon settlement of the Purchase Contracts underlying
such Securities) entitling them, for a period expiring within 45 days after the
record date for the determination of shareholders entitled to receive such
rights, options or warrants, to subscribe for or purchase 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, options or warrants (other than pursuant to a dividend reinvestment
plan), 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, the numerator of which shall be the number
of shares of Common Stock outstanding at the close of business on the date fixed
for such determination plus the number of shares of Common Stock which the
aggregate of the offering price of the total number of shares of Common Stock so
offered for subscription or purchase would purchase at such Current Market Price
and the denominator of which 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

                                       36

<Page>

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 issue any such rights, options
or warrants in respect of Common Stock held in the treasury of the Company.

            (3) In case outstanding 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 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 or warrants referred to in
paragraph (2) of this Section, any dividend or distribution paid exclusively in
cash and any dividend or distribution referred to in paragraph (1) of this
Section), 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, the numerator of which
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 determined by the
Board of Directors, whose determination shall be conclusive and described in a
Board Resolution filed with the Agent) of the portion of the assets or evidences
of indebtedness so distributed applicable to one share of Common Stock and the
denominator of which shall be such Current Market Price per Ordinary Share, 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 shall not be applicable.

            (5) In case the Company shall, (I) by dividend or otherwise,
distribute to all holders of its Common Stock cash (excluding any cash that is
distributed in a Reorganization Event to which Section 5.5(b) applies or as part
of a distribution referred to in paragraph (4) of this Section) in an aggregate
amount that, combined together with (II) the aggregate amount of any other
distributions to all holders of its Common Stock made exclusively in cash within
the 12 months preceding the date of payment of such distribution and in respect
of which no adjustment pursuant to this paragraph (5) or paragraph (6) of this
Section has been made, exceeds 5% of the product of the Current Market Price per
share of Common Stock on the date for the determination of holders of Common
Stock entitled to receive such distribution times the number of shares of Common
Stock outstanding on such date, then, and in each such case, immediately after
the close of business on such date for determination, the Settlement Rate 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 the date
fixed for determination of the stockholders entitled to receive such
distribution by a fraction (i) the numerator of which shall be equal to the
Current Market Price per share of Common Stock on the date fixed for such

                                       37

<Page>

determination less an amount equal to the quotient of (x) the combined amount
distributed or payable in the transactions described in clauses (I) and (II)
above and (y) the number of shares of Common Stock outstanding on such date for
determination and (ii) the denominator of which shall be equal to the Current
Market Price per share of Common Stock on such date for determination.

            (6) In case (I) a tender or exchange offer made by the Company or
any subsidiary of the Company for shares of Common Stock in a transaction or
series of transactions which is subject to Rule 13e-4 under the Exchange Act
("Tender or Exchange Offer") 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) of an aggregate
consideration having a fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution) that combined together with (II) the aggregate of the cash plus
the fair market value (as determined by the Board of Directors, whose
determination shall be conclusive and described in a Board Resolution), as of
the expiration of such Tender or Exchange Offer, of consideration payable in
respect of any other Tender or Exchange Offer, by the Company or any
subsidiary of the Company for all or any portion of the Common Stock expiring
within the 12 months preceding the expiration of such Tender or Exchange
Offer and in respect of which no adjustment pursuant to this paragraph (6)
has been made and (III) the aggregate amount of any distributions to all
holders of the Company's Common Stock made exclusively in cash (excluding any
cash that is distributed in a Reorganization Event to which Section 5.5(b)
applies or as part of a distribution referred to in paragraph (4) of this
Section) within the 12 months preceding the expiration of such Tender or
Exchange Offer and in respect of which no adjustment pursuant to paragraph
(5) of this Section or this 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), (II) and
(III) above (assuming in the case of clause (I) the acceptance, up to any
maximum specified in the terms of the Tender or Exchange Offer, of Purchased
Shares), and (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

                                       38

<Page>

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 5.4(b) applies) shall be deemed to involve
(a) a distribution of such securities other than Common Stock to all holders of
Common Stock (and the effective date of such reclassification shall be deemed to
be "the date fixed for the determination of stockholders entitled to receive
such distribution" and the "date fixed for such determination" within the
meaning of paragraph (4) of this Section), and (b) 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 day
means the average of the daily Closing Prices for the 5 consecutive Trading Days
selected by the Company commencing not more than 30 Trading Days before, and
ending not later than, the earlier of the day in question 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 the
Common Stock trades regular way 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 therein; 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 pursuant to paragraph (1), (2),
(3), (4), (5), (6), (7) or (10) of this Section 5.5(a), an adjustment shall also
be made to the Applicable Market Value solely to determine which of clauses (a),
(b) or (c) of the definition of Settlement Rate in Section 5.1 will apply on the
Purchase Contract Settlement Date. Such adjustment shall be made by multiplying
the Applicable Market Value by a fraction, the numerator of which shall be the
Settlement Rate immediately after such adjustment pursuant to paragraph (1),
(2), (3), (4), (5), (6), (7) or (10) of this Section 5.5(a) and the denominator
of which shall be the Settlement Rate immediately before 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) (7) or (10) of this Section 5.5(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 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

                                       39

<Page>

income tax to any holders of Common Stock resulting from any dividend or
distribution of stock or issuance of rights or warrants to purchase or
subscribe for stock or from any event treated as such for income tax purposes
or for any other reasons.

      (b) ADJUSTMENT FOR CONSOLIDATION, MERGER OR OTHER REORGANIZATION EVENT.
In the event of (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 Common Stock outstanding
immediately prior to the merger or consolidation is not exchanged for cash,
securities or other property of the Company or another corporation), (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
exchange of securities of the Company with another Person (other than in
connection with a merger or acquisition) or (iv) any liquidation, dissolution
or winding up of the Company other than as a result of or after the
occurrence of a Termination Event (any such event, a "Reorganization Event"),
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 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 or dissolution of the
Company, the Company or a liquidating trust created in connection therewith,
shall execute and deliver to the Agent an agreement supplemental hereto
providing that the Holders of each Outstanding Security shall have the rights
provided by this Section 5.5. Such supplemental agreement shall provide for
adjustments which, for events subsequent to the effective date of such
supplemental agreement, shall be as nearly equivalent as may be practicable
to the adjustments provided for in this Section. The above provisions of this
Section shall similarly apply to successive Reorganization Events.

Section 5.6.      NOTICE OF ADJUSTMENTS AND CERTAIN OTHER EVENTS.

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

                  (i) forthwith compute the Settlement Rate in accordance with
      Section 5.5 and prepare and transmit to the Agent an Officer's 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 5.5 (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 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 Agent shall not be accountable
with respect to the validity or value (or the kind or amount) of any 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 Agent makes no
representation with respect thereto. The Agent shall not be responsible for
any failure of the Company to issue, transfer or deliver any 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 5.7.      TERMINATION EVENT; NOTICE.

      The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights and
obligations of Holders to purchase Common Stock, shall immediately and
automatically terminate, without the necessity of any notice or action by any
Holder, the Agent or the Company, if, on or prior to the 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 Senior Notes, forming a part of such Securities in
the case of Income PRIDES, or Treasury Securities in the case of Growth
PRIDES, in accordance with the provisions of Section 4.3 of the Pledge
Agreement. Upon the occurrence of a Termination Event, the Company shall
promptly but in no event later than two Business Days thereafter give written
notice to the Agent, the Collateral Agent and to the Holders, at their
addresses as they appear in the Register.

Section 5.8.      EARLY SETTLEMENT.

      (a) Subject to and upon compliance with the provisions of this Section
5.8, at the option of the Holder thereof, Purchase Contracts underlying
Securities, having an aggregate Stated Amount equal to $1,000 or an integral
multiple thereof, may be settled early ("Early Settlement") in the case of
Income PRIDES on or prior to the fifth Business Day immediately preceding the
Purchase Contract Settlement Date and in the case of Growth PRIDES on or
prior to the second

                                      41
<Page>

Business Day immediately preceding the Purchase Contract Settlement Date, in
each case, as provided herein. 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 such Certificate to the Agent
at the Corporate Trust Office duly endorsed for transfer to the Company or in
blank with the form of Election to Settle Early on the reverse thereof duly
completed and accompanied by payment (payable to the Company in immediately
available funds in an amount (the "Early Settlement Amount") equal to (i) the
product of (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) in the case of Income PRIDES Certificates, 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 sum of the dividends on
the related Senior Notes payable on such Payment Date. Except as provided in
the immediately preceding sentence, no payment or adjustment shall be made
upon Early Settlement of any Purchase Contract on account of any dividends on
the Common Stock issued upon such Early Settlement. If the foregoing
requirements are first satisfied with respect to Purchase Contracts
underlying any Securities at or prior to 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 that is not a Business Day,
the "Early Settlement Date" with respect to such Securities shall be the next
succeeding Business Day.

      (b) 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, 0.2974 shares 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. As promptly as practicable
after Early Settlement of Purchase Contracts in accordance with the
provisions of this Section 5.8, the Company shall issue and shall deliver to
the Agent at the Corporate Trust Office 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 5.9.

      (c) No later than the third Business Day after the applicable Early
Settlement Date the Company shall cause (i) the Common Stock issuable upon
Early Settlement of Purchase Contracts to be issued and delivered, and (ii)
the related Senior Notes, in the case of Income PRIDES, or the related
Treasury Securities, in the case of Growth PRIDES, to be released from the
Pledge by the Collateral Agent and transferred, in each case to the Agent for
delivery to the Holder thereof or its designee.

      (d) Upon Early Settlement of any Purchase Contracts, and subject to
receipt of Common Stock from the Company and the Senior Notes, or Treasury
Securities, as the case may be, from the Collateral Agent, as applicable, the
Agent shall, in accordance with the instructions provided by the Holder
thereof on the applicable form of Election to Settle Early on the reverse of
the Certificate evidencing the related Securities, (i) transfer to the Holder
the Senior Notes or Treasury Securities, as the case may be, forming a part
of such Securities, and (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 5.9.

                                      42
<Page>

      (e) 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
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.

Section 5.9.      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 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 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 Agent from
time to time with sufficient funds to permit the Agent to make all cash
payments required by this Section 5.9 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 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 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.     EARLY SETTLEMENT UPON MERGER.

      (a) In the event of a merger or consolidation of the Company of the
type described in Section 5.5(b) in which the Common Stock outstanding
immediately prior to such merger or consolidation is exchanged for
consideration consisting of at least 30% cash or cash equivalents (any such
event a "Cash Merger"), then the Company (or the successor to the Company
hereunder) shall be required to offer the Holder of each Income PRIDES the
right to settle the Purchase Contract underlying such Income PRIDES prior to
the Purchase Contract Settlement Date ("Merger Early Settlement") as provided
herein. On or before the fifth Business Day after the consummation of a Cash
Merger the Company or, at the written request and expense of the Company, the
Agent shall give all Holders notice, in the manner provided in Section 1.6,
of the occurrence of the Cash Merger and of the right of Merger Early
Settlement arising as a result

                                      43
<Page>

thereof. The Company shall also deliver a copy of such notice to the Agent
and the Collateral Agent. Each such notice shall contain:

                  (i)  the date on which the Merger Early Settlement will be
      effected (the "Merger Early Settlement Date");

                  (ii) the date, which shall be 10 days after the date of the
      notice, by which the Merger Early Settlement right must be exercised;

                  (iii) the Settlement Rate in effect as a result of such Cash
      Merger and the kind and amount of securities, cash and other property
      receivable by the Holder upon settlement of each Purchase Contract
      pursuant to Section 5.5(b);

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

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

      (b) To exercise a Merger Early Settlement right, a Holder shall deliver
to the Agent on or before 5:00 p.m., New York City time on the date specified
in the notice the Income PRIDES Certificate(s) with respect to which the
Merger Early Settlement right is being exercised with the form of "Election
to Settle Early" on the reverse thereof, duly completed accompanied by
payment of the purchase price for the property to be purchased pursuant to
the Purchase Contracts underlying such Income PRIDES, which payment shall be
made in lawful money of the United States by certified or cashier's check
payable to the order of the Company in immediately available funds in an
amount equal to the aggregate Stated Amount of the Income PRIDES in respect
of which the Merger Early Settlement is being effected less the amount of
cash that otherwise would be deliverable by the Company or its successor upon

good faith of the claims or defenses made by such party litigant; provided
that

                                      45

extent that it may lawfully do so) hereby expressly waives all benefit or
advantage of any such law and covenants that it will not hinder, delay or
impede the execution of any power herein granted to the Agent or the Holders,
but will suffer and permit the execution of every such power as though no
such law had been enacted.

            (1) the Agent fails to comply with Section 310(b) of the TIA, as if
      the 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; or

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

then, in any such case, (i) the Company by a Board Resolution may remove the
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 Agent and

or if a vacancy shall occur in the office of Agent for any cause, the Company,
by a Board Resolution, shall promptly appoint a successor Agent and shall comply
with the applicable requirements of Section 7.10. If no successor Agent shall
have been so appointed by the Company and accepted appointment in the manner
required by Section 7.10, any Holder who has been a bona fide Holder of 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
appointment of a successor Agent.

      (f) The Company shall give, or shall cause such successor Agent to give,
notice of each resignation and each removal of the Agent and each appointment of

shall become vested with all the rights, powers, agencies and duties of the

                                     50

retiring Agent; but, on the request of the Company or the successor Agent, such
retiring Agent shall, upon payment of its charges, execute and deliver an
instrument transferring to such successor Agent all the rights, powers and
trusts of the retiring Agent and shall duly assign, transfer and deliver to such
successor Agent all property and money held by such retiring Agent hereunder.

any and all instruments for more fully and certainly vesting in and confirming
to such successor Agent all such rights, powers and agencies referred to in

without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Certificates shall have been
authenticated and executed on behalf of the Holders, but not delivered, by the
Agent then in office, any successor by merger, conversion or consolidation to
such Agent may adopt such authentication and execution and deliver the
Certificates so authenticated and executed with the same effect as if such
successor Agent had itself authenticated and executed such Securities.

Section 7.12.     PRESERVATION OF INFORMATION; COMMUNICATIONS TO HOLDERS.

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

writing to the Agent, and furnish to the 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
Agent shall, mail to all the Holders copies of the form of proxy or other

after a tender to the 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 AGENT.

      Except to the extent otherwise provided in this Agreement, the 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

Contracts on behalf of the Holders, except to the extent expressly provided
in Article Five hereof.

provisions of Section 7.1(a)(2) hereof.

      (c) The Agent shall maintain all appropriate records documenting
compliance with such requirements, and shall make such records available, on

Outstanding Certificates.

      The Company covenants that it will not merge or consolidate with any other
Person or sell, assign, transfer, lease or convey all or substantially all of
its properties and assets to any Person or group of affiliated Persons in one

Section 9.2.      RIGHTS AND DUTIES OF SUCCESSOR CORPORATION.

      In case of any such consolidation, merger, sale, assignment, transfer,
lease or conveyance and upon any such assumption by a successor corporation in
accordance with Section 9.1, 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 Affiliated Managers Group,
Inc. any or all of the Certificates evidencing Securities issuable hereunder
which theretofore shall not have been signed by the Company and delivered to the
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 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 Agent for authentication and
execution, and any Certificate evidencing Securities which such successor
corporation thereafter shall cause to be signed and delivered to the Agent for
that purpose. All the Certificates so 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 consolidation, merger, 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 9.3.      OPINION OF COUNSEL GIVEN TO AGENT.

      The Agent, subject to Sections 7.1 and 7.3, shall receive an Opinion of
Counsel as conclusive evidence that any such consolidation, merger, sale,
assignment, transfer, lease or conveyance, and any such assumption, complies
with the provisions of this Article and that all conditions precedent to the
consummation of any such consolidation, merger, sale, assignment, transfer,
lease or conveyance have been met.

surrendered for registration of transfer or exchange, for a Collateral
Substitution or re-establishment of an Income PRIDES and where notices and
demands to or

                                     55

upon the Company in respect of the Securities and this Agreement may be
served. The Company will give prompt written notice to the Agent of the

shall fail to furnish the Agent with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office, and the Company hereby appoints the Agent as its agent to receive all
such presentations, surrenders, notices and demands.

      The Company may also from time to time designate one or more other offices
or agencies where Certificates may be presented or surrendered for any or all
such purposes and may from time to time rescind such designations; provided,
however, that no such designation or rescission shall in any manner relieve the
Company of its obligation to maintain an office or agency in the Borough of
Manhattan, The City of New York for such purposes. The Company will give prompt
written notice to the Agent of any such designation or rescission and of any
change in the location of any such other office or agency. The Company hereby
designates as the place of payment for the Securities the Corporate Trust Office

constituting a part of the Securities evidenced by Outstanding Certificates.

tender of payment in respect of any Purchase Contract constituting a part of the
Outstanding Securities will, upon issuance, be duly authorized, validly issued,
fully paid and nonassessable.

Pledge pursuant to the Pledge Agreement, to the Agent to the account designated
by the Agent, no later than 2:00 p.m., New York City time, on the Business Day

payment shall be made no later than 10:30 a.m., New York City time, on the next
succeeding Business Day) and (ii) in the case of payments of principal on any
pledged Senior Notes or the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury

Agreement, as the case may be, to the Company on the Purchase Contract
Settlement Date (as defined herein) in accordance with the terms of the Pledge
Agreement, in full satisfaction of the respective obligations of the Holders of
the Income PRIDES of which such pledged Senior Notes or the Treasury Portfolio,
as the case may be, are a part under the Purchase Contracts forming a part of
such Income PRIDES. Interest on any Senior Notes or distributions on the

2004 (the "Purchase Contract Settlement Date"), at a price equal to $25 (the
"Stated Amount"), a number of newly issued shares of Common Stock, $0.01 par
value ("Common Stock"), of the Company equal to the Settlement Rate, unless on
or prior to the Purchase Contract Settlement Date there shall have occurred a
Termination Event or an Early Settlement with respect to the Income PRIDES 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 (1) cash received from a
Holder or (2) payment received in respect of the Senior Notes or the appropriate
Applicable Ownership Interest (as specified in clause (A) of the definition of
such term) of the

                (Form of Reverse of Income PRIDES Certificate)

      Each Purchase Contract evidenced hereby is governed by a Purchase Contract
Agreement, dated as of December 21, 2001 (as may be supplemented from time to
time, the "Purchase Contract Agreement"), between the Company and First Union
National Bank, a national banking association, as Purchase Contract Agent
(including its successors thereunder, herein called the "Agent"), to which
Purchase Contract Agreement and supplemental agreements thereto reference is
hereby made for a description of the respective rights, limitations of rights,
obligations, duties and immunities thereunder of the Agent, the Company and the
Holders and of the terms upon which the Income PRIDES Certificates are, and are
to be, executed and delivered. In the case of any inconsistency between this
Certificate and the terms of the Purchase Contract Agreement, the terms of the
Purchase Contract Agreement shall prevail.

      Each Purchase Contract evidenced hereby obligates the Holder of this
Income PRIDES Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at a price equal to the Purchase Price, a number of
newly issued shares of Common Stock of the Company equal to the Settlement Rate,
unless, on or prior to the Purchase Contract Settlement Date, there shall have
occurred a Termination Event or an Early Settlement with respect to the Security
of which such Purchase Contract is a part. The "Settlement Rate" is equal to (a)
if the Applicable Market Value (as defined below) is equal to or greater than
$84.0650 (the "Threshold Appreciation Price"), 0.2974 shares of Common Stock per
Purchase Contract, (b) if the Applicable Market Value is less than the Threshold
Appreciation Price but is greater than $73.10, the number of shares of Common
Stock per Purchase Contract equal to the Stated Amount divided by the Applicable
Market Value and (c) if the Applicable Market Value is less than or equal to
$73.10, 0.3420 shares of Common Stock per Purchase Contract, in each case
subject to adjustment as provided in the Purchase Contract Agreement. No
fractional shares of Common Stock will be issued upon settlement of Purchase
Contracts, as provided in 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
Income PRIDES to purchase at the Purchase Price, and the Company to sell, a
number of newly issued shares of Common Stock equal to the Early Settlement Rate
or the Settlement Rate, as applicable.

      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
or, for purposes of determining cash payable in lieu of factional shares in
connection with an Early Settlement, the third Trading Day immediately preceding
the relevant Early Settlement Date.

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

                                       62

<Page>

Stock is not so reported, the last quoted bid price for the Common Stock in
the over-the-counter market as reported by the National Quotation Bureau or
similar organization, or, if such bid price is not available, the market
value of the Common Stock on such date as determined by a nationally
recognized independent investment banking firm retained for this purpose by
the Company. A "Trading Day" means a day on which the Common Stock (A) is not
suspended from trading on any national or regional securities exchange or
association or over-the-counter market at the close of business and (B) has
traded at least once on the national or regional securities exchange or
association or over-the-counter market that is the primary market for the
trading of the Common Stock.

      In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Income PRIDES Certificate shall 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 a remarketing of the related pledged Senior Notes of such holders or
of the appropriate Applicable Ownership Interest of the Treasury Portfolio.
Unless a Tax Event Redemption or a Successful Initial Remarketing has occurred,
a Holder of Income PRIDES who does not elect to make an effective (1) Cash
Settlement on or prior to 5:00 p.m., New York City time, on the fifth Business
Day immediately preceding the Purchase Contract Settlement Date, or (2) Early
Settlement on or prior to 5:00 p.m. New York City time, on the fifth Business
Day immediately preceding the Purchase Contract Settlement Date, shall pay the
Purchase Price for the shares of Common Stock to be issued under the related
Purchase Contract from the Proceeds of the sale of the related pledged Senior
Notes held by the Collateral Agent. Unless a Tax Event Redemption or a
Successful Initial Remarketing has occurred, such sale will be made by the
Remarketing Agent pursuant to the terms of the Remarketing Agreement and any
supplemental remarketing agreement executed in connection therewith between the
parties thereto, on the third Business Day immediately preceding the Purchase
Contract Settlement Date. If a Tax Event Redemption or a Successful Initial
Remarketing has occurred, a Holder of Income PRIDES who does not elect to make
an effective Early Settlement on or prior to 5:00 p.m. New York City time, on
the second Business Day immediately preceding the Purchase Contract Settlement
Date shall pay the Purchase Price with the Proceeds at maturity of the
Applicable Ownership Interest (as defined in clause (A) of the definition of
such term) of the Treasury Portfolio.

      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 in full of the aggregate Purchase
Price for the shares of Common Stock to be purchased thereunder in the manner
herein set forth.

      Under the terms of the Pledge Agreement, the Agent will be entitled to
exercise the voting and any other consensual rights pertaining to the pledged
Senior Notes. Upon receipt of notice of any meeting at which holders of Senior
Notes are entitled to vote or upon the solicitation of consents, waivers or
proxies of holders of Senior Notes, the Agent shall, as soon as practicable
thereafter, mail to the Income PRIDES holders a notice (a) containing such
information as is contained in the notice or solicitation, (b) stating that each
Income PRIDES holder on the record date set by the Agent therefor (which, to the
extent possible, shall be the same date as the record date for determining the
holders of Senior Notes entitled to vote) shall be entitled to instruct the
Agent as to the exercise of the voting rights pertaining to the Senior Notes

                                       63

<Page>

constituting a part of such holder's Income PRIDES and (c) stating the manner in
which such instructions may be given. Upon the written request of the Income
PRIDES Holders on such record date, the Agent shall endeavor insofar as
practicable to vote or cause to be voted, in accordance with the instructions
set forth in such requests, the maximum number of Senior Notes as to which any
particular voting instructions are received. In the absence of specific
instructions from the Holder of an Income PRIDES, the Agent shall abstain from
voting the Senior Notes evidenced by such Income PRIDES.

      Upon the occurrence of a Tax Event Redemption prior to the Purchase
Contract Settlement Date, pursuant to the terms of the Pledge Agreement, the
Collateral Agent will apply, out of the aggregate Redemption Price for the
Senior Notes that are components of Income PRIDES, an amount equal to the
aggregate Redemption Amount for the Senior Notes that are components of Income
PRIDES to purchase on behalf of the Holders of Income PRIDES, the Treasury
Portfolio and, after deducting the Remarketing Fee to the extent permitted under
the terms of the Remarketing Agreement, promptly remit the remaining portion of
such Redemption Price to the Agent for payment to the Holders of such Income
PRIDES.

      Upon the occurrence of a Successful Initial Remarketing, pursuant to the
terms of the Remarketing Agreement, the Remarketing Agent will apply an amount
equal to the Treasury Portfolio Purchase Price to purchase on behalf of the
Holders of Income PRIDES, the Treasury Portfolio, and, after deducting the
Remarketing Fee to the extent permitted under the terms of the Remarketing
Agreement, promptly remit the remaining portion of such Proceeds of the
Successful Initial Remarketing to the Agent for payment to the Holders of such
Income PRIDES.

      Following the occurrence of a Tax Event Redemption prior to the Purchase
Contract Settlement Date or following a Successful Initial Remarketing, the
Holders of Income PRIDES and the Collateral Agent shall have such security
interests, rights and obligations with respect to the Treasury Portfolio as the
Holder of Income PRIDES and the Collateral Agent had in respect of the Senior
Notes, as the case may be, subject to the Pledge thereof as provided in Articles
2, 3, 4, 5 and 6 of the Pledge Agreement and any reference herein to the Senior
Notes shall be deemed to be a reference to such Treasury Portfolio and any
reference herein or in the Certificates to interest on the Senior Notes shall be
deemed to be a reference to corresponding distributions on the Treasury
Portfolio.

      The Income PRIDES Certificates are issuable only in registered form and
only in denominations of a single Income PRIDES and any integral multiple
thereof. The transfer of any Income PRIDES Certificate will be registered and
Income PRIDES Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Income PRIDES Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents permitted by the
Purchase Contract Agreement. No service charge shall be required for any such
registration of transfer or exchange, but the Company and the Agent may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. A Holder who elects to substitute Treasury
Securities for Senior Notes or the appropriate Applicable Ownership Interest of
the Treasury Portfolio, thereby creating Growth PRIDES, shall be responsible for
any fees or expenses payable in connection therewith. Except as provided in the
Purchase Contract Agreement, for so long as the Purchase Contract underlying an

its

constituent parts, and the rights and obligations of the Holder of such
Income PRIDES in respect of Senior Notes or the appropriate Applicable
Ownership Interest of the Treasury Portfolio, as the case may be, and the
Purchase Contract constituting such Income PRIDES may be transferred and
exchanged only as an Income PRIDES. A Holder of an Income PRIDES may create a
Growth PRIDES by delivering to the Collateral Agent Treasury Securities in an
aggregate principal amount equal to the aggregate principal amount of the
pledged Senior 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, in exchange for the release of such pledged
Senior Notes or the appropriate Applicable Ownership Interest of the Treasury
Portfolio, as the case may be, in accordance with the terms of the Purchase
Contract Agreement and the Pledge Agreement. From and after such Collateral
Substitution, the Security for which such pledged Treasury Securities secures
the Holder's obligation under the Purchase Contract shall be referred to as a
"Growth PRIDES." A Holder may make such Collateral Substitution only in
integral multiples of 40 Income PRIDES for 40 Growth PRIDES; provided,
however, that if a Tax Event Redemption or a Successful Initial Remarketing
has occurred and the Treasury Portfolio has become a component of the Income
PRIDES, a Holder may make such Collateral Substitutions only in integral
multiples of 8,000 Income PRIDES for 8,000 Growth PRIDES. Such Collateral
Substitution may cause the equivalent aggregate Stated Amount of this
Certificate to be increased or decreased; provided, however, the equivalent
aggregate Stated Amount outstanding under this Income PRIDES Certificate
shall not exceed $200,000,000. All such adjustments to the equivalent
aggregate Stated Amount of this Income PRIDES Certificate shall be duly
recorded by placing an appropriate notation on the Schedule attached hereto.

      A Holder of Growth PRIDES may recreate Income PRIDES by delivering to the
Collateral Agent Senior Notes or the appropriate Applicable Ownership Interest
of the Treasury Portfolio, with an aggregate principal amount, in the case of
such Senior Notes, or with the appropriate Applicable Ownership Interest (as
specified in clause (A) of the definition of such term) of the Treasury
Portfolio, in the case of such appropriate Applicable Ownership Interest of the
Treasury Portfolio, equal to the aggregate principal amount 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. Any such recreation of an Income PRIDES may be effected
only in multiples of 40 Growth PRIDES for 40 Income PRIDES; provided, however,
that if a Tax Event Redemption or a Successful Initial Remarketing has occurred
and the Treasury Portfolio has become a component of the Income PRIDES, a Holder
may make such substitution only in integral multiples of 8,000 Growth PRIDES for
8,000 Income PRIDES.

      The Purchase Contracts and all obligations and rights of the Company and
the Holders thereunder shall immediately and automatically terminate, without
the necessity of any notice or action by any Holder, the Agent or the Company,
if, on or prior to the 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 Agent, the Collateral Agent and to the Holders, at their
addresses as they appear in the Income PRIDES Register. Upon and after the
occurrence of a Termination Event, the Collateral Agent shall release the Senior
Notes or the appropriate Applicable Ownership Interest 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 Holders thereof, Purchase Contracts
underlying Securities having an aggregate Stated Amount equal to $1,000 or an
integral multiple thereof may be settled early ("Early Settlement") as provided
in the Purchase Contract Agreement; provided, however, that if a Tax Event
Redemption or a Successful Initial Remarketing has occurred and the Treasury
Portfolio has become a component of the Income PRIDES, Holders may early settle
Income PRIDES only in integral multiples of 8,000 Income PRIDES. In order to
exercise the right to effect Early Settlement with respect to any Purchase
Contracts evidenced by this Income PRIDES Certificate, the Holder of this Income
PRIDES Certificate shall deliver this Income PRIDES Certificate to the Agent at
the Corporate Trust Office or the New York Office duly endorsed for transfer to
the Company or in blank with the form of Election to Settle Early set forth
below duly completed and accompanied by payment in lawful money of the United
States by certified or cashiers check or wire transfer, in each case in
immediately available funds payable to the Company in an amount (the "Early
Settlement Amount") equal to (i) the product of (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, interest, if any, 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 Senior Notes or the appropriate Applicable
Ownership Interest of the Treasury Portfolio 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 an Income PRIDES as to which Early
Settlement is effected equal to the Early Settlement Rate. The Early Settlement
Rate shall initially be equal to 0.2974 shares of Common Stock and 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 Income PRIDES Certificate in
accordance with the Purchase Contract Agreement, the transferee shall be bound
(without the necessity of any other action on the part of such transferee,
except as may be required by the Agent pursuant to the Purchase Contract
Agreement) under the terms of the Purchase Contract Agreement, the Pledge
Agreement and the Purchase Contracts evidenced hereby and the transferor shall
be released from the obligations under the Purchase Contract Agreement, the
Pledge Agreement and the Purchase Contracts evidenced by this Income PRIDES
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 Income PRIDES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Income PRIDES evidenced hereby on his behalf as his
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 agrees to perform
its obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Pledge Agreement on its behalf as its attorney-in-fact, and consents to the
Pledge of the Senior Notes or the appropriate Applicable Ownership

Interest of the Treasury Portfolio, as the case may be, underlying this
Income PRIDES Certificate pursuant to the Pledge Agreement and to all other
provisions of 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,
Proceeds of the pledged Senior Notes or the appropriate Applicable Ownership
Interest (as specified in clause (A) of the definition of such term) of the
Treasury Portfolio 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 Proceeds.

      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 then outstanding.

      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 principles of conflicts of laws.

      The Company, the Agent and its Affiliates and any agent of the Company or
the Agent may treat the Person in whose name this Income PRIDES Certificate is
registered as the owner of the Income PRIDES evidenced hereby for the purpose of
receiving payments of interest payable quarterly on the Senior Notes or on the
maturing quarterly interest strips of the Treasury Portfolio, as applicable,
whether or not any payments in respect thereof be overdue and notwithstanding
any notice to the contrary, and neither the Company, the Agent nor any such
agent shall be affected by notice to the contrary.

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

      A copy of the Purchase Contract Agreement is available for inspection at
the offices of the Agent.

Number of Growth PRIDES

                            Growth PRIDES Certificate

      This Growth PRIDES Certificate certifies that Cede & Co. is the registered
Holder of the number of Growth PRIDES set forth above. Each Growth PRIDES
represents (i) a 1/40th, or 2.5%, undivided beneficial ownership interest in 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 Affiliated Managers Group, Inc., a Delaware corporation (the
"Company"). All capitalized terms used herein which are defined in the Purchase
Contract Agreement have the meaning set forth therein.

      Pursuant to the Pledge Agreement, the Treasury Securities constituting
part of each Growth PRIDES 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 a portion of such Growth PRIDES.

      The Pledge Agreement provides that all payments of the principal of any
Treasury Securities received by the Collateral Agent shall be paid by the
Collateral Agent by wire transfer in same day funds (i) in the case of any
principal payments with respect to any Treasury Securities that have been
released from the Pledge pursuant to the Pledge Agreement, to the Holders of the
applicable Growth PRIDES to the accounts designated by them in writing for

                                       74

<Page>

such purpose no later than 2:00 p.m., New York City time, on the Business Day
such payment is received by the Collateral Agent (provided that in the event
such payment is received by the Collateral Agent on a day that is not a
Business Day or after 12:30 p.m., New York City time, on a Business Day, then
such payment shall be made no later than 10:30 a.m., New York City time, on
the next succeeding Business Day), and (ii) in the case of the principal of
any pledged Treasury Securities, to the Company on the Purchase Contract
Settlement Date (as defined herein) in accordance with the terms of the
Pledge Agreement, in full satisfaction of the respective obligations of the
Holders of the Growth PRIDES of which such pledged Treasury Securities are a
part under the Purchase Contracts forming a part of such Growth PRIDES.

      Each Purchase Contract evidenced hereby obligates the Holder of this
Growth PRIDES Certificate to purchase, and the Company to sell, on November 17,
2004 (the "Purchase Contract Settlement Date"), at a price equal to $25 (the
"Stated Amount"), a number of newly issued shares of Common Stock, par value
$0.1 ("Common Stock"), of the Company equal to the Settlement Rate, unless on or
prior to the Purchase Contract Settlement Date there shall have occurred a
Termination Event or an Early Settlement with respect to the Growth PRIDES 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 pledged to secure the obligations under such Purchase
Contract in accordance with the terms of the Pledge Agreement.

      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
Agent by manual signature, this Growth PRIDES 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.

                (Form of Reverse of Growth PRIDES Certificate)

      Each Purchase Contract evidenced hereby is governed by a Purchase Contract
Agreement, dated as of December 21, 2001 (as may be supplemented from time to
time, the "Purchase Contract Agreement"), between the Company and First Union
National Bank, a national banking association, as Purchase Contract Agent
(including its successors thereunder, herein called the "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 Agent, the Company and the
Holders and of the terms upon which the Growth PRIDES Certificates are, and are
to be, executed and delivered. In the case of any inconsistency between this
Certificate and the terms of the Purchase Contract Agreement, the terms of the
Purchase Contract Agreement shall prevail.

      Each Purchase Contract evidenced hereby obligates the Holder of this
Growth PRIDES Certificate to purchase, and the Company to sell, on the Purchase
Contract Settlement Date at the Purchase Price, a number of newly issued shares
of Common Stock of the Company equal to the Settlement Rate, unless, on or prior
to the Purchase Contract Settlement Date, there shall have occurred a
Termination Event or an Early Settlement with respect to the Security of which
such Purchase Contract is a part. The "Settlement Rate" is equal to (a) if the
Applicable Market Value (as defined below) is equal to or greater than $84.0650
(the "Threshold Appreciation Price"), 0.2974 shares of Common Stock per Purchase
Contract, (b) if the Applicable Market Value is less than the Threshold
Appreciation Price but is greater than $73.10, the number of shares of Common
Stock per Purchase Contract equal to the Stated Amount divided by the Applicable
Market Value and (c) if the Applicable Market Value is less than or equal to
$73.10, 0.3420 shares of Common Stock per Purchase Contract, in each case
subject to adjustment as provided in the Purchase Contract Agreement. No
fractional shares of Common Stock will be issued upon settlement of Purchase
Contracts, as provided in the Purchase Contract Agreement.

      Each Purchase Contract evidenced hereby which is settled through Early
Settlement shall obligate the Holder of the related Growth PRIDES to purchase at
the Purchase Price, and the Company to sell, a number of newly issued shares of
Common Stock equal to the Early Settlement Rate.

      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
or, for purposes of determining cash payable in lieu of fractional shares in
connection with an Early Settlement, the third Trading Day immediately preceding
the relevant Early Settlement Date.

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

                                       77

<Page>

Common Stock in the over-the-counter market as reported by the National
Quotation Bureau or similar organization, or, if such bid price is not
available, the market value of the Common Stock on such date as determined by
a nationally recognized independent investment banking firm retained for this
purpose by the Company. A "Trading Day" means a day on which the Common Stock
(A) is not suspended from trading on any national or regional securities
exchange or association or over-the-counter market at the close of business
and (B) has traded at least once on the national or regional securities
exchange or association or over-the-counter market that is the primary market
for the trading of the Common Stock.

      In accordance with the terms of the Purchase Contract Agreement, the
Holder of this Growth PRIDES Certificate shall pay the Purchase Price for the
shares of Common Stock purchased pursuant to each Purchase Contract evidenced
hereby by effecting either an Early Settlement of each such Purchase Contract or
by applying a principal amount of the pledged Treasury Securities underlying
such Holder's Growth PRIDES equal to the Stated Amount to the purchase of the
Common Stock. A Holder of Growth PRIDES who does not elect, on or prior to 5:00
p.m., New York City time, on the second Business Day immediately preceding the
Purchase Contract Settlement Date, to make an Early Settlement, shall pay the
Purchase Price for the shares of Common Stock to be issued on the related
Purchase Contract by applying a principal amount of the pledged Treasury
Securities as aforesaid.

      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 in full of the aggregate Purchase
Price for the shares of Common Stock to be purchased thereunder in the manner
herein set forth.

      The Growth PRIDES Certificates are issuable only in registered form and
only in denominations of a single Growth PRIDES and any integral multiple
thereof. The transfer of any Growth PRIDES Certificate will be registered and
Growth PRIDES Certificates may be exchanged as provided in the Purchase Contract
Agreement. The Growth PRIDES Registrar may require a Holder, among other things,
to furnish appropriate endorsements and transfer documents permitted by the
Purchase Contract Agreement. No service charge shall be required for any such
registration of transfer or exchange, but the Company and the Agent may require
payment of a sum sufficient to cover any tax or other governmental charge
payable in connection therewith. A Holder who elects to substitute Senior Notes
or the appropriate Applicable Ownership Interest of the Treasury Portfolio, as
the case may be, for Treasury Securities, thereby recreating Income PRIDES,
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 Growth PRIDES remains in effect, such Growth
PRIDES shall not be separable into its constituent parts, and the rights and
obligations of the Holder of such Growth PRIDES in respect of the Treasury
Security and the Purchase Contract constituting such Growth PRIDES may be
transferred and exchanged only as a Growth PRIDES. A Holder of Growth PRIDES may
recreate Income PRIDES by delivering to the Collateral Agent Senior Notes or the
appropriate Applicable Ownership Interest of the Treasury Portfolio, with an
aggregate principal amount, in the case of such Senior Notes, or with the
appropriate Applicable Ownership Interest (as specified in clause (A) of the
definition of such term) of the Treasury Portfolio, in the case of such
appropriate Applicable Ownership Interest of the Treasury Portfolio, equal to
the aggregate principal amount of the pledged Treasury Securities in exchange
for the release of such pledged

                                       78

<Page>

Treasury Securities in accordance with the terms of the Purchase Contract
Agreement and the Pledge Agreement. From and after such substitution, the
Security for which such pledged Senior Notes or appropriate Applicable
Ownership Interest of the Treasury Portfolio, as the case may be, secures the
Holder's obligation under the Purchase Contract shall be referred to as an
"Income PRIDES." A Holder may make such a substitution only in integral
multiples of 40 Growth PRIDES for 40 Income PRIDES; provided, however, that
if a Tax Event Redemption or a Successful Initial Remarketing has occurred
and the Treasury Portfolio has become a component of the Income PRIDES, a
Holder may make such substitution only in integral multiples of 8,000 Growth
PRIDES for 8,000 Income PRIDES. Such substitution may cause the equivalent
aggregate Stated Amount of this Certificate to be increased or decreased;
provided, however, the equivalent aggregate Stated Amount outstanding under
this Growth PRIDES Certificate shall not exceed $200,000,000. All such
adjustments to the equivalent aggregate Stated Amount of this Growth PRIDES
Certificate shall be duly recorded by placing an appropriate notation on the
Schedule attached hereto.

      A Holder of an Income PRIDES may create a Growth PRIDES by delivering to
the Collateral Agent Treasury Securities in an aggregate principal amount of the
pledged Senior 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, in exchange for the release of such pledged
Senior Notes or the appropriate Applicable Ownership Interest of the Treasury
Portfolio, as the case may be, in accordance with the terms of the Purchase
Contract Agreement and the Pledge Agreement. Any such creation of a Growth
PRIDES may be effected only in multiples of 40 Income PRIDES for 40 Growth
PRIDES; provided, however, if a Tax Event Redemption or a Successful Initial
Remarketing has occurred and the Treasury Portfolio has become a component of
the Income PRIDES, a Holder may make such Collateral Substitution only in
integral multiples of 8,000 Income PRIDES for 8,000 Growth PRIDES.

      The Purchase Contracts and all obligations and rights of the Company and
the Holders thereunder shall immediately and automatically terminate, without
the necessity of any notice or action by any Holder, the Agent or the Company,
if, on or prior to the 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 Agent, the Collateral Agent and to the Holders, at their
addresses as they appear in the Growth PRIDES 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.

      Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holders thereof, Purchase Contracts
underlying Securities having an aggregate Stated Amount equal to $1,000 or an
integral multiple thereof 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 Growth
PRIDES Certificate, the Holder of this Growth PRIDES Certificate shall deliver
this Growth PRIDES Certificate to the Agent at the Corporate Trust Office or the
New York Office duly endorsed for transfer to the Company or in blank with the
form of Election to Settle Early set forth below duly completed and accompanied
by payment in lawful money of the United States by certified or cashiers check
or wire transfer, in each case in immediately available funds

                                     79

<Page>

payable to the Company in an amount (the "Early Settlement Amount") equal to
(i) the product of (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, interest, if any, 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 Growth
PRIDES as to which Early Settlement is effected equal to the Early Settlement
Rate. The Early Settlement Rate shall initially be equal to 0.2974 shares of
Common Stock and 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 Growth PRIDES Certificate, the
transferee shall be bound (without the necessity of any other action on the part
of such transferee, except as may be required by the Agent pursuant to the
Purchase Contract Agreement) under the terms of the Purchase Contract Agreement,
the Pledge Agreement and the Purchase Contracts evidenced hereby and the
transferor shall be released from the obligations under the Purchase Contract
Agreement, the Pledge Agreement and the Purchase Contracts evidenced by this
Growth PRIDES Certificate. The Company covenants and agrees, and the Holder, by
his acceptance hereof, likewise covenants and agrees, to be bound by the
provisions of this paragraph.

      The Holder of this Growth PRIDES Certificate, by its acceptance hereof,
authorizes the Agent to enter into and perform the related Purchase Contracts
forming part of the Growth PRIDES evidenced hereby on his 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 agrees to perform
its obligations under such Purchase Contracts, consents to the provisions of the
Purchase Contract Agreement, authorizes the Agent to enter into and perform the
Pledge Agreement on its behalf as its attorney-in-fact, and consents to the
Pledge of the Treasury Securities underlying this Growth PRIDES Certificate
pursuant to the Pledge Agreement and to all other provisions of 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, Proceeds 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
Proceeds.

      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 then outstanding.

                                     80

      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 principles of conflicts of laws.

      The Company, the Agent and its Affiliates and any agent of the Company or
the Agent may treat the Person in whose name this Growth PRIDES Certificate is
registered as the owner of the Growth PRIDES evidenced hereby for the purpose of
receiving payments on the Treasury Securities, 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 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 Agent.

                               TO COLLATERAL AGENT

[Collateral Agent Address]

Re: Feline PRIDES of Affiliated Managers Group, Inc. (the "Company")

      We hereby notify you in accordance with Section [4.1] [4.2] of the
Pledge Agreement, dated as of December 21, 2001, (the "Pledge Agreement")
among the Company, yourselves, as Collateral Agent, Custodial Agent and
Securities Intermediary and ourselves, as Purchase Contract Agent and as
attorney-in-fact for the holders of [Income PRIDES] [Growth PRIDES] from time
to time, that the holder of the Securities listed below (the "Holder") has
elected to substitute [$_____ aggregate principal amount of Treasury

and in effect from time to time, the "Purchase Contract Agreement"), pursuant
to which there may be issued up to 8,000,000 FELINE PRIDES of the Company

Underwriting Agreement, dated December 18, 2001, among the Company and the
Underwriters (as defined therein) is exercised in full), having a stated
amount of $25 (the "Stated Amount") per FELINE PRIDES.

      The FELINE PRIDES will initially consist of 8,000,000 units (referred

      As provided herein, holders of Income PRIDES may substitute collateral

the Income PRIDES, the "Securities"). Each Growth PRIDES so created will be
comprised of (a) a Purchase Contract under which the holder will purchase
from the Company not later than the Purchase Contract Settlement Date, for an
amount in cash equal to the Stated Amount, a number of shares of Common Stock
equal to the Settlement Rate, and (b) a 1/40th undivided beneficial interest
in a zero-coupon U.S. Treasury Security (CUSIP No. 912803 AB9) having a
principal amount at

      Section 2.1 THE PLEDGE. The Holders from time to time acting through
the Purchase Contract Agent, as their attorney-in-fact, and the Purchase
Contract Agent, as such attorney-in-fact, hereby pledge and grant to the
Collateral Agent, for the benefit of the Company, as collateral security for
the performance when due by such Holders of their respective obligations
under the related Purchase Contracts, a security interest in all of the
right, title and interest of the Purchase Contract Agent and such Holders (a)
in the Senior Notes constituting a part of the Securities and any Treasury
Securities delivered in exchange for any Senior Notes (or, if applicable, the
Portfolio Interests) in accordance with Section 4.1 hereof, and any Senior
Notes (or, if applicable any Portfolio Interests) delivered in exchange for
any Treasury Securities, in accordance with Section 4.2 hereof, in each case
that have been Transferred to or received by the Collateral Agent and not
released by the Collateral Agent to such Holders under the provisions of this
Agreement; (b) in payments made by Holders pursuant to Section 4.4; (c) in
the Collateral Account and all securities, financial assets, Cash and other
property credited thereto and all Security Entitlements related thereto; (d)
in the Portfolio Interests and the Treasury Portfolio purchased on behalf of
the Holders of Income PRIDES by the Collateral Agent upon the occurrence of a
Successful Initial Remarketing or a Tax Event Redemption as provided in
Article VI, or otherwise; and (e) all Proceeds of the foregoing (all of the
foregoing, collectively, the "Collateral"). Prior to or concurrently with the
execution and delivery of this Agreement, the Purchase Contract Agent, on
behalf of the initial Holders of the Securities, shall cause the Senior Notes
comprising a part of the Income PRIDES to be Transferred to the Collateral
Agent for the benefit of the Company. Without limiting and in furtherance of
the foregoing, on such date, the Purchase Contract Agent on behalf of the
Holders, and as their attorney-in-fact, shall Transfer the Senior Global Note
(as defined in the Indenture) indorsed in blank or together with such powers
indorsed in blank as the Collateral Agent or the Company may request to the
Collateral Agent, which Transfer shall constitute delivery (as defined in
Section 8-301 of the Code) of the Senior Notes. On any date on which the
Senior Global Note (or any other security certificate (as defined in Section
8-102(a)(16) of the Code) evidencing all or a portion or the Pledged Senior

                                      5
<Page>

Notes) shall be Transferred to a clearing corporation (as defined in Section
8-102(a)(5) of the Code) (as contemplated in Section 2.3 of the First
Supplemental Indenture) the Purchase Contract Agent on behalf of the Holders,
and as their attorney-in-fact, shall Transfer the Senior Notes, or cause the
Senior Notes to be Transferred, to the Collateral Account maintained by the
Collateral Agent at the Securities Intermediary by book-entry transfer to the
Collateral Account in accordance with applicable law including, without
limitation, the TRADES Regulations. If, at any time, the Global Senior Note
(as defined in the Indenture) shall be exchanged for Senior Notes in
definitive registered form pursuant to Section 2.3 of the First Supplemental
Indenture (or otherwise pursuant to the Indenture) evidenced by one or more
securities certificates (as defined in Section 8-102(a)(16) of the Code), the
Purchase Contract Agent, on behalf of the Holders, and as their
attorney-in-fact, shall forthwith Transfer to the Collateral Agent such
security certificates evidencing the Senior Notes, indorsed in blank or
together with such powers indorsed in blank as the Collateral Agent or the
Company may request. In the event a Holder of Income PRIDES so elects, such
Holder may Transfer Treasury Securities to the Collateral Agent for the
benefit of the Company in exchange for the release by the Collateral Agent on
behalf of the Company to the Purchase Contract Agent of Senior Notes or
Portfolio Interests, as the case may be, with a Stated Amount equal to the
aggregate principal amount of the Treasury Securities so Transferred, in the
case of the Senior Notes, or in the case of Portfolio Interests, equal to the
aggregate principal amount of the Treasury Securities so transferred. In the
event a Holder of Growth PRIDES so elects, such Holder may Transfer Senior
Notes or Portfolio Interests to the Collateral Agent for the benefit of the
Company in exchange for the release by the Collateral Agent on behalf of the
Company to the Purchase Contract Agent of Treasury Securities with an
aggregate principal amount at maturity equal to the aggregate principal
amount of the Senior Notes or such Portfolio Interests, so transferred to the
Purchase Contract Agent on behalf of such Holder. Such Treasury Securities
and Portfolio Interests, as applicable, shall be Transferred to the
Collateral Account maintained by the Collateral Agent at the Securities
Intermediary by book-entry transfer to the Collateral Account in accordance
with the TRADES Regulations and other applicable law and by the notation by
the Securities Intermediary on its books that a Security Entitlement with
respect to such Treasury Securities or such Portfolio Interests has been
credited to the Collateral Account. For purposes of perfecting the Pledge
under applicable law, including, to the extent applicable, the TRADES
Regulations or the Uniform Commercial Code as adopted and in effect in any
applicable jurisdiction, the Collateral Agent shall be the agent of the
Company as provided herein. The pledge provided in this Section 2.1 is herein
referred to as the "Pledge" and the Senior Notes, the Treasury Securities and
the Portfolio Interests subject to the Pledge, excluding any Senior Notes
that are delivered pursuant to Section 6.4 hereof, Treasury Securities or
Portfolio Interests released from the Pledge as provided in Sections 4.1 and
4.2 hereof, respectively, are hereinafter referred to as the "Pledged Senior
Notes," "Pledged Treasury Securities" and the "Pledged Portfolio Interests,"
respectively. Subject to the Pledge and the provisions of Section 2.2 hereof,
the Holders from time to time shall have full beneficial ownership of the
Collateral. Whenever directed by the Collateral Agent acting on behalf of the
Company, the Securities Intermediary shall have the right to reregister the
Senior Notes or any other Securities held in physical form in its name.

      Except as may be required in order to release Senior Notes in
connection with a Holder's election to convert its investment from an Income
PRIDES to a Growth PRIDES, or except as otherwise required to release
Securities as specified herein, neither the Collateral Agent nor the
Securities Intermediary shall relinquish physical possession of any security
certificate evidencing

                                       6
<Page>

a Senior Note prior to the termination of this Agreement except Senior Notes
may be held in any clearing corporation in an account including only assets
of customers of the Collateral Agent or Securities Intermediary. If it
becomes necessary for the Securities Intermediary to relinquish physical
possession of a security certificate in order to release a portion of the
Pledged Senior Notes evidenced thereby from the Pledge, the Securities
Intermediary shall use its best efforts to obtain physical possession of a
replacement security certificate evidencing any Senior Notes remaining
subject to the Pledge hereunder registered to it or indorsed in blank within
fifteen days of the date it relinquished possession. The Securities
Intermediary shall promptly notify the Company and the Collateral Agent of
the Securities Intermediary's failure to obtain possession of any such
replacement certificate as required hereby.

      Section 2.2 CONTROL AND PERFECTION. (a) In connection with the Pledge
granted in Section 2.1, and subject to the other provisions of this
Agreement, the Holders from time to time acting through the Purchase Contract

Purchase Contract Agent or any of the Holders), and the Securities
Intermediary agrees, to comply with and follow any instructions and
entitlement orders (as defined in Section 8-102(a)(8) of the Code) that the
Collateral Agent on behalf of the Company may give in writing with respect to
the Collateral Account, the Collateral credited thereto and any Security
Entitlements with respect to any thereof. Such instructions and entitlement
orders may, without limitation, direct the Securities Intermediary to
transfer, redeem, sell, liquidate, assign, deliver or otherwise dispose of
the Senior Notes, the Treasury Securities, the Portfolio Interests and any
Security Entitlements with respect thereto and to pay and deliver any income,
proceeds or other funds derived therefrom to the Company. The Holders from
time to time acting through the Purchase Contract Agent hereby further
authorize and direct the Collateral Agent, as Agent of the Company, to itself
issue instructions and entitlement orders, and to otherwise take action, with
respect to the Collateral Account, the Collateral credited thereto and any
Security Entitlements with respect thereto, pursuant to the terms and
provisions hereof, all without the necessity of obtaining the further consent
of the Purchase Contract Agent or any of the Holders. The Collateral Agent
shall be the agent of the Company and shall act as directed in writing by the
Company. Without limiting the generality of the foregoing, the Collateral
Agent shall issue entitlement orders to the Securities Intermediary when and
as directed by the Company.

            (b) The Securities Intermediary hereby confirms and agrees that:
(i) it is a Person that in the ordinary course of business maintains
securities accounts for others and is acting in that capacity, (ii) all
securities or other property underlying any financial assets credited to the
Collateral Account shall be registered in the name of the Securities
Intermediary, indorsed to the Securities Intermediary or in blank or credited
to another Collateral Account maintained in the name of the Securities
Intermediary and in no case will any financial asset credited to the
Collateral Account be registered in the name of the Purchase Contract Agent,
the Collateral Agent, the Company or any Holder, payable to the order of, or
specially indorsed to, the Purchase Contract Agent, the Collateral Agent, the
Company or any Holder except to the extent the foregoing have been specially
indorsed to the Securities Intermediary or in blank; (iii) all property
delivered to the Securities Intermediary pursuant to this Pledge Agreement
(including, without limitation, any Senior Notes, the Portfolio Interests or
Treasury Securities) will be promptly credited to the Collateral Account;
(iv) the Collateral Account is an account to which financial assets are or
may be credited, and the Securities Intermediary shall, subject to the terms

                                       7
<Page>

of this Agreement, treat the Purchase Contract Agent as entitled to
exercise the rights of any financial asset credited to the Collateral Account;
(v) the Securities Intermediary has not entered into, and until the termination
of this Agreement will not enter into, any agreement with any other person
relating to the Collateral Account and/or any financial assets credited thereto
pursuant to which it has agreed to comply with entitlement orders (as defined in
Section 8-102(a)(8) of the Code) of such other person; and (vi) the Securities
Intermediary has not entered into, and until the termination of this Agreement
will not enter into, any agreement with the Company, the Collateral Agent or the
Purchase Contract Agent purporting to limit or condition the obligation of the
Securities Intermediary to comply with entitlement orders as set forth in this
Section 2.2 hereof.

            (c) The Securities Intermediary hereby agrees that each item of
property (whether investment property, financial asset, security, instrument or
cash) credited to the Collateral Account shall be treated as a "financial asset"
within the meaning of Section 8-102(a)(9) of the Code.

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

            (e) The Purchase Contract Agent hereby irrevocably constitutes and
appoints the Collateral Agent and the Company, with full power of substitution,
as the Purchase Contract Agent's attorney-in-fact to take on behalf of, and in
the name, place and stead of the Purchase Contract Agent and the Holders, any
action necessary or desirable to perfect and to keep perfected the security
interest in the Collateral referred to in Section 2.1. The grant of such
power-of-attorney shall not be deemed to require of the Collateral Agent any
specific duties or obligations not otherwise assumed by the Collateral Agent
hereunder.

                                   ARTICLE III
                       Distributions on Pledged Collateral

      So long as the Purchase Contract Agent is the owner of the Pledged Senior
Notes and is acting in such capacity, it shall receive all payments thereon. If
the Pledged Senior Notes are issued in registered form (as defined in
8-102(a)(13)) or thereafter reregistered, such that the Collateral Agent becomes
the registered holder, all payments of the Stated Amount, or interest payments
on, the Pledged Senior Notes or, if applicable, the Pledged Portfolio Interests,
as the case may be, and all payments of the principal of, or cash distributions
on, any Pledged Treasury Securities or Pledged Portfolio Interests received by

            principal amount, with respect to any Senior Notes or Portfolio
            Interests, as the case may be, that have been released from the
            Pledge pursuant to Section 4.1 or Section 4.3 hereof, to the
            Purchase Contract Agent, for the benefit of the relevant Holders of
            Securities, to the account designated by the Purchase Contract Agent
            for such purpose, no later

                                     8

<Page>

            than 2:00 p.m., New York City time, on the Business Day such
            payment is received by the Collateral Agent (provided that in the
            event such payment is received by the Collateral Agent on a day
            that is not a Business Day or after 12:30 p.m., New York City
            time, on a Business Day, then such payment shall be made no later
            than 10:30 a.m., New York City time, on the next succeeding
            Business Day);

                 (ii) In the case of any principal payments with respect to any
            Treasury Securities that have been released from the Pledge pursuant
            to Section 4.2 or Section 4.3 hereof, to the Purchase Contract Agent
            for the benefit of the Holders of the Growth PRIDES, to the accounts
            designated by them in writing for such purpose no later than 2:00
            p.m., New York City time, on the Business Day such payment is
            received by the Collateral Agent (provided that in the event such
            payment is received by the Collateral Agent on a day that is not a
            Business Day or after 12:30 p.m., New York City time, on a Business
            Day, then such payment shall be made no later than 10:30 a.m., New
            York City time, on the next succeeding Business Day); and

            may be, or the principal of any Pledged Treasury Securities, to the
            Company on the Purchase Contract Settlement Date in accordance with

            satisfaction of the respective obligations of the Holders under the

            the Purchase Price, to the Purchase Contract Agent for the benefit
            of the Holders.

      All payments received by the Purchase Contract Agent as provided herein
shall be applied by the Purchase Contract Agent pursuant to the provisions of
the Purchase Contract Agreement. If, notwithstanding the foregoing, the Purchase
Contract Agent shall receive any payments of the Stated Amount on account of any

payment, is a Pledged Senior Note or a Holder of a Growth PRIDES shall receive

benefit of the Company (and promptly deliver the same over to the Company) for
application to the obligations of the Holders under the related Purchase
Contracts, and the Holders shall acquire no right, title or interest in any such
payments of Stated Amount or principal so received.

      Section 4.1 SUBSTITUTION FOR SENIOR NOTES AND THE CREATION OF GROWTH
PRIDES. At any time on or prior to the fifth Business Day immediately preceding
the Purchase Contract Settlement Date (or on or prior to the second Business Day
immediately preceding the Purchase Contract Settlement Date, if a Tax Event
Redemption or a Successful Initial Remarketing has occurred), a Holder of Income

                                     9

<Page>

the Pledged Senior Notes (or, if a Tax Event Redemption or a Successful
Initial Remarketing has occurred, the appropriate Portfolio Interests)
securing such Holder's obligations under the Purchase Contract(s) comprising
a part of its Income PRIDES in integral multiples of 40 Income PRIDES by (a)
Transferring to the Collateral Agent Treasury Securities having a Value equal
to the aggregate Stated Amount of the Pledged Senior Notes (or appropriate
Portfolio Interests, as the case may be), to be released and (b) delivering
the related Income PRIDES to the Purchase Contract Agent, accompanied by a
notice, substantially in the form of Exhibit B hereto, to the Purchase
Contract Agent stating that such Holder has Transferred Treasury Securities
to the Collateral Agent pursuant to clause (a) above (stating the Value of
the Treasury Securities Transferred by such Holder) and requesting that the
Purchase Contract Agent instruct the Collateral Agent to release from the
Pledge the Pledged Senior Notes or the appropriate Portfolio Interests, as
the case may be, related to such Income PRIDES. The Purchase Contract Agent
shall instruct the Collateral Agent in the form provided in Exhibit A;
provided, however, that if a Tax Event Redemption or a Successful Initial
Remarketing has occurred and the Portfolio Interests have become a component
of the Income PRIDES, Holders of Income PRIDES may make such substitution
only in integral multiples of 8,000 Income PRIDES at any time on or prior to
the second Business Day immediately preceding the Purchase Contract
Settlement Date. Upon receipt of Treasury Securities from a Holder of Income
PRIDES and the related instruction from the Purchase Contract Agent, the
Collateral Agent shall release the Pledged Senior Notes or the Pledged
Portfolio Interests, as the case may be, and shall promptly Transfer such
Pledged Senior Notes or the appropriate Portfolio Interests, as the case may
be, free and clear of any lien, pledge or security interest created hereby,
to the Purchase Contract Agent. All items Transferred and/or substituted by
any Holder pursuant to this Section 4.1, Section 4.2 or any other Section of
this Agreement shall be Transferred and/or substituted free and clear of all
liens, claims and encumbrances.

      Section 4.2 SUBSTITUTION OF TREASURY SECURITIES AND THE CREATION OF INCOME
PRIDES. At any time on or prior to the fifth Business Day immediately preceding
the Purchase Contract Settlement Date (or on or prior to the second Business Day
immediately preceding the Purchase Contract Settlement Date, if a Tax Event
Redemption or a Successful Initial Remarketing has occurred), a Holder of Growth
PRIDES shall have the right to reestablish Income PRIDES consisting of the
Purchase Contracts and Senior Notes in integral multiples of 40 Income PRIDES by
(a) Transferring to the Collateral Agent Senior Notes having a Value equal to
the Value of the Pledged Treasury Securities to be released (or the appropriate
Portfolio Interests having a Value equal to the Value of the Pledged Treasury
Securities to be released) and (b) delivering the related Growth PRIDES to the
Purchase Contract Agent, accompanied by a notice, substantially in the form of
Exhibit B hereto, to the Purchase Contract Agent stating that such Holder has
transferred the relevant amount of Senior Notes (or the appropriate Portfolio
Interests, as the case may be) to the Collateral Agent pursuant to clause (a)
above and requesting that the Purchase Contract Agent instruct the Collateral
Agent to release from the Pledge the Pledged Treasury Securities related to such
Growth PRIDES. The Purchase Contract Agent shall instruct the Collateral Agent
in the form provided in Exhibit A; provided, however, that if a Tax Event
Redemption or a Successful Initial Remarketing has occurred and the Treasury
Portfolio has become a component of the Income PRIDES, Holders of Growth PRIDES
may make such substitution only in integral multiples of 8,000 Growth PRIDES at
any time on or prior to the second Business Day immediately preceding the
Purchase Contract Settlement Date. Upon receipt of the Senior Notes or the
Portfolio Interests as the case may be, from such Holder and

                                    10

<Page>

the instruction from the Purchase Contract Agent, the Collateral Agent shall
release the Treasury Securities having a corresponding aggregate principal
amount from the Pledge and shall promptly Transfer such Treasury Securities,
free and clear of any lien, pledge or security interest created hereby, to
the Purchase Contract Agent.

      Section 4.3 TERMINATION EVENT. Upon receipt by the Collateral Agent of
written notice from the Company or the Purchase Contract Agent that there has
occurred a Termination Event, the Collateral Agent shall release all Collateral
from the Pledge and shall promptly Transfer any Pledged Senior Notes (or
Portfolio Interests if a Tax Event Redemption or a Successful Initial
Remarketing has occurred) and Pledged Treasury Securities to the Purchase
Contract Agent for the benefit of the Holders of the Income PRIDES and the
Growth PRIDES, respectively, free and clear of any lien, pledge or security
interest or other interest created hereby.

      If such Termination Event shall result from the Company's becoming a
debtor under any applicable uniform bankruptcy laws, and if the Collateral Agent
shall for any reason fail promptly to effectuate the release and Transfer of all
Pledged Senior Notes, the Pledged Portfolio Interests or of the Pledged Treasury
Securities, as the case may be, as provided by this Section 4.3, the Purchase
Contract Agent shall (i) use its best efforts to obtain an opinion of a
recognized law firm practicing law in the applicable jurisdiction to the effect
that, as a result of the Company's being the debtor in such a bankruptcy case,
the Collateral Agent will not be prohibited from releasing or Transferring the
Collateral as provided in this Section 4.3, and shall deliver such opinion to
the Collateral Agent within ten days after the occurrence of such Termination
Event, and if (y) the Purchase Contract Agent shall be unable to obtain such
opinion within ten days after the occurrence of such Termination Event or (z)
the Collateral Agent shall continue, after delivery of such opinion, to refuse
to effectuate the release and Transfer of all Pledged Senior Notes, the Pledged
Portfolio Interests or the Pledged Treasury Securities, as the case may be, as
provided in this Section 4.3, then the Purchase Contract Agent shall within
fifteen days after the occurrence of such Termination Event commence an action
or proceeding in the court with jurisdiction of the Company's case under the any
such applicable bankruptcy laws seeking an order requiring the Collateral Agent
to effectuate the release and transfer of all Pledged Senior Notes, the Pledged
Portfolio Interests or of the Pledged Treasury Securities, as the case may be,
as provided by this Section 4.3 or (ii) commence an action or proceeding like
that described in subsection (i)(z) hereof within ten days after the occurrence
of such Termination Event.

      Section 4.4 CASH SETTLEMENT. (a) Upon receipt by the Collateral Agent of
(i) a notice from the Purchase Contract Agent promptly after the receipt by the
Purchase Contract Agent of such notice that a Holder of an Income PRIDES or
Growth PRIDES has elected, in accordance with the procedures specified in
Section 5.3(a)(i) or (d)(i) of the Purchase Contract Agreement, respectively, to
settle its Purchase Contract with Cash and (ii) payment of the amount required
to settle such contract by such Holder on or 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 immediately available funds payable to or upon the order of the
Company, then the Collateral Agent shall promptly invest any Cash received from
a Holder in connection with a Cash Settlement in Permitted Investments. Upon
receipt of the proceeds upon the maturity of the Permitted Investments on the
Purchase Contract Settlement Date, the Collateral Agent shall pay the portion of
such proceeds and deliver

                                    11

<Page>

any certified or cashiers' checks received and any funds so wired, in an
aggregate amount equal to the Purchase Price, to the Company on the Purchase
Contract Settlement Date, and shall distribute any funds in respect of the
interest earned from the Permitted Investments to the Purchase Contract Agent
for payment to the relevant Holder.

            (b) If neither a Tax Event Redemption or a Successful Initial
Remarketing has occurred, and a Holder of an Income PRIDES fails to notify the
Purchase Contract Agent of its intention to make a Cash Settlement in accordance
with Section 5.3(a)(i) of the Purchase Contract Agreement, such failure shall
constitute an event of default under the Purchase Contract Agreement and
hereunder, and the Holder shall be deemed to have consented to the disposition
of the Pledged Senior Notes pursuant to the remarketing as described in Section
5.3(b) of the Purchase Contract Agreement, which is incorporated herein by
reference. If a Holder of an Income PRIDES does notify the Purchase Contract
Agent as provided in Section 5.3(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 Section 5.3(a)(ii) of the Purchase Contract Agreement, such failure
will constitute an event of default under the Purchase Contract Agreement and
hereunder, and the Senior Notes of such a Holder will not be remarketed but
instead the Collateral Agent, for the benefit of the Company, will exercise its
rights as a secured party with respect to such Senior Notes at the written
direction of the Company to retain or dispose of the Collateral in accordance
with applicable law. In addition, in the event of a Failed Secondary Remarketing
as described in Section 5.3(b) of the Purchase Contract Agreement, such Failed
Secondary Remarketing shall constitute an event of default hereunder by such
Holder and the Collateral Agent, for the benefit of the Company, will also
exercise its rights as a secured party with respect to such Senior Notes at the
written direction of the Company to retain or dispose of the Collateral in
accordance with applicable law.

            (c) If a Holder of a Growth PRIDES (unless a Tax Event Redemption or
a Successful Initial Remarketing has occurred) fails to notify the Purchase
Contract Agent of such Holder's intention to make a Cash Settlement in
accordance with Section 5.3(d)(i) of the Purchase Contract Agreement, or if a
Holder of a Growth PRIDES does notify the Purchase Contract Agent as provided in
paragraph 5.3(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 5.3(d)(ii) of the Purchase Contract Agreement, such failure shall
constitute an event of default hereunder by such Holder and upon the maturity of
any Pledged Treasury Securities, if any, held by the Collateral Agent on the
Business Day immediately preceding the Purchase Contract Settlement Date, the
principal amount at maturity of the Pledged Treasury Securities or the Pledged
Portfolio Interests, received by the Collateral Agent shall, upon written
direction of the Company, be invested promptly in any Permitted Investments. On
the Purchase Contract Settlement Date, an amount equal to the Purchase Price
will be remitted to the Company as payment thereof. In the event the sum of the
proceeds from the related Pledged Treasury Securities 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 will
distribute such excess to the Purchase Contract Agent for the benefit of the
Holder of the related Growth PRIDES or Income PRIDES when received.

      Section 4.5 EARLY SETTLEMENT. Upon written notice to the Collateral Agent
by the Purchase Contract Agent that one or more Holders of Securities have
elected to effect Early

                                     12

<Page>

Settlement of their respective obligations under the Purchase Contracts
forming a part of such Securities in accordance with the terms of the
Purchase Contracts and the Purchase Contract Agreement (setting forth the
number of such Purchase Contracts as to which such Holders have elected to
effect Early Settlement), and that the Purchase Contract Agent has received
from such Holders, 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, (a) Pledged Senior Notes or the Pledged
Portfolio Interests, as the case may be, in the case of a Holder of Income
PRIDES or (b) Pledged Treasury Securities in the case of a Holder of Growth
PRIDES, as the case may be, with a principal amount at maturity equal to the
product of (i) the Stated Amount times (ii) the number of such Purchase
Contracts as to which such Holders have elected to effect Early Settlement
and shall Transfer all such Pledged Senior Notes, the Pledged Portfolio
Interests, or Pledged Treasury Securities, as the case may be, free and clear
of the Pledge created hereby, to the Purchase Contract Agent for the benefit
of the Holders.

      Section 4.6 APPLICATION OF PROCEEDS SETTLEMENT. (a) In the event a Holder
of Income PRIDES (unless a Tax Event Redemption or a Successful Initial
Remarketing has occurred) has not elected to make an effective Cash Settlement
by notifying the Purchase Contract Agent in the manner provided for in paragraph
5.3(a)(i) in the Purchase Contract Agreement or has not made an Early Settlement
of the Purchase Contract(s) underlying its Income PRIDES, such Holder shall be
deemed to have elected to pay for the Common Stock to be issued under such
Purchase Contract(s) from the Proceeds of the related Pledged Senior Notes. The
Collateral Agent shall, by 10:00 a.m., New York City time, on the fourth
Business Day immediately preceding the Purchase Contract Settlement Date,
without any instruction from such Holder of Income PRIDES, present the related
Pledged Senior Notes to the Remarketing Agent for remarketing. Upon receiving
such Pledged Senior Notes, the Remarketing Agent, pursuant to the terms of the
Remarketing Agreement and the Remarketing Underwriting Agreement, will use its
reasonable efforts to remarket such Pledged Senior Notes on such date at a price
not less than approximately 100.5% of the aggregate Value of such Pledged Senior
Notes, plus accrued and unpaid interest, if any, thereon. After deducting as the
remarketing fee an amount not exceeding 25 basis points (0.25%) of the aggregate
Value of the Pledged Senior Notes from any amount of such Proceeds in excess of
the aggregate Value, plus such accrued and unpaid interest of the remarketed
Pledged Senior Notes, the Remarketing Agent will remit the entire amount of the
Proceeds of such remarketing to the Collateral Agent. On the Purchase Contract
Settlement Date, the Collateral Agent shall apply that portion of the Proceeds
from such remarketing equal to the aggregate Value, plus such accrued and unpaid
interest of such Pledged Senior Notes, to satisfy in full the obligations of
such Holders of Income PRIDES to pay the Purchase Price to purchase the Common
Stock under the related Purchase Contracts. The remaining portion of such
Proceeds, if any, shall be distributed by the Collateral Agent to the Purchase
Contract Agent for payment to the Holders. If the Remarketing Agent advises the
Collateral Agent in writing that it cannot remarket the related Pledged Senior
Notes of such Holders of Income PRIDES at a price not less than 100% of the
aggregate Value of such Pledged Senior Notes plus any accrued and unpaid
interest, thus resulting in a Failed Secondary Remarketing and an event of
default under the Purchase Contract Agreement and hereunder, the Collateral
Agent, for the benefit of the Company will, at the written direction of the
Company, retain or dispose of the Pledged Senior

                                     13

<Page>

Notes in accordance with applicable law and satisfy in full, from any such
disposition or retention, such Holder's obligation to pay the Purchase Price
for the Common Stock.

            (b) In the event a Holder of Growth PRIDES (if a Tax Event
Redemption or a Successful Initial Remarketing has occurred) has not made an
Early Settlement of the Purchase Contract(s) underlying its Growth PRIDES, such
Holder shall be deemed to have elected to pay for the Common Stock to be issued
under such Purchase Contract(s) from the Proceeds of the related Pledged
Treasury Securities or the appropriate Portfolio Interests, as the case may be.
On the Business Day immediately prior to the Purchase Contract Settlement Date,
the Collateral Agent shall invest the Cash proceeds of the maturing Pledged
Treasury Securities, or the maturing appropriate Portfolio Interests, as the
case may be, in any overnight Permitted Investments. Without receiving any
instruction from any such Holder of Growth PRIDES, the Collateral Agent shall
apply the Proceeds of the related Pledged Treasury Securities or appropriate
Portfolio Interests 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 appropriate Portfolio Interests, as the case may be, and the
investment earnings from the investment in overnight Permitted Investments is in
excess of the aggregate Purchase Price of the Purchase Contracts being settled
thereby, the Collateral Agent shall distribute such excess, when received, to
the Purchase Contract Agent for the benefit of the Holder.

            (c) Pursuant to the Remarketing Agreement and subject to the terms
of the Remarketing Underwriting Agreement, on or prior to the fifth Business Day
immediately preceding the Initial Remarketing Date or the Secondary Remarketing
Date, as applicable, but no earlier than the Payment Date immediately preceding
such date, holders of Separate Senior Notes may elect to have their Separate
Senior Notes remarketed by delivering their Separate Senior Notes, together with
a notice of such election, substantially in the form of Exhibit C hereto, to the
Custodial Agent. The Custodial Agent will hold such Separate Senior Notes in an
account separate from the Collateral Account. A holder of Separate Senior Notes
electing to have its Separate Senior Notes remarketed will also have the right
to withdraw such election by written notice to the Custodial Agent,
substantially in the form of Exhibit D hereto, on or prior to the second
Business Day immediately preceding the Initial Remarketing Date or the Secondary
Remarketing Date, as applicable, upon which notice the Custodial Agent will
return such Separate Senior Notes to such holder. On the Business Day
immediately preceding the Initial Remarketing Date or the Secondary Remarketing
Date, as applicable, the Custodial Agent shall notify the Remarketing Agent of
the aggregate principal amount of the separate Notes to be remarketed and will
deliver to the Remarketing Agent for remarketing all Separate Senior Notes
delivered to the Custodial Agent pursuant to this Section 4.6(c) and not
withdrawn pursuant to the terms hereof prior to such date. The portion of the
proceeds from such remarketing equal to the aggregate Value of such Separate
Senior Notes will automatically be remitted by the Remarketing Agent to the
Custodial Agent for the benefit of the holders of such Separate Senior Notes. In
addition, after deducting as the remarketing fee an amount not exceeding 25
basis points (0.25%) of the Value of the remarketed Separate Senior Notes, from
any amount of such proceeds in excess of the aggregate Value of the remarketed
Separate Senior Notes plus any accrued and unpaid interest thereon, the
Remarketing Agent will remit to the Custodial Agent the remaining portion of the
proceeds, if any, for the benefit of such holders. If, despite using its

                                     14

<Page>

reasonable efforts, the Remarketing Agent advises the Custodial Agent in writing
that it cannot remarket the related Separate Senior Notes of such holders at a
price not less than 100% of the aggregate Value of such Separate Senior Notes
plus accrued and unpaid interest and thus resulting in a Failed Initial
Remarketing or a Failed Secondary Remarketing, the Remarketing Agent will
promptly return such Senior Notes to the Custodial Agent for redelivery to such
holders.

                                    ARTICLE V
                           Voting Rights -Senior Notes

      Provided no default hereunder or under the Purchase Contract exists, the
Purchase Contract Agent may exercise, or refrain from exercising, any and all
voting and other consensual rights pertaining to the Pledged Senior Notes or any
part thereof for any purpose not inconsistent with the terms of this Agreement
and in accordance with the terms of the Purchase Contract Agreement; provided,
that the Purchase Contract Agent shall not exercise or, as the case may be,
shall not refrain from exercising such right if, in the judgment of the Company,
such action would impair or otherwise have a material adverse effect on the
value of all or any of the Pledged Senior Notes; and provided, further, that the
Purchase Contract Agent shall give the Company and the Collateral Agent at least
five days' prior written notice of the manner in which it intends to exercise,
or its reasons for refraining from exercising, any such right. Upon receipt of
any notices and other communications in respect of any Pledged Senior Notes,
including notice of any meeting at which holders of Senior Notes are entitled to
vote or solicitation of consents, waivers or proxies of holders of Senior 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 Senior Notes (in form and
substance satisfactory to the Collateral Agent) as are prepared by the Purchase
Contract Agent with respect to the Pledged Senior Notes.

                                   ARTICLE VI
                               Rights and Remedies

      Section 6.1 RIGHTS AND REMEDIES OF THE COLLATERAL AGENT. (a) In addition
to the rights and remedies specified in Section 4.4 hereof or otherwise
available at law or in equity, after an event of default hereunder, the
Collateral Agent shall have all of the rights and remedies with respect to the
Collateral of a secured party under the Uniform Commercial Code (or any
successor thereto) as in effect in the State of New York from time to time (the
"Code") (whether or not the Code is in effect in the jurisdiction where the
rights and remedies are asserted) and the TRADES Regulations and such additional
rights and remedies to which a secured party is entitled under the laws in
effect in any jurisdiction where any rights and remedies hereunder may be
asserted. Wherever reference is made in this Agreement to any section of the
Code, such reference shall be deemed to include a reference to any provision of
the Code which is a successor to, or amendment of, such section. Without
limiting the generality of the foregoing, such remedies may include, to the
extent permitted by applicable law, (i) retention of the Pledged Senior Notes or
other Collateral in full satisfaction of the Holders' obligations under the
Purchase Contracts or (ii) sale of the Pledged Senior Notes or other Collateral
in one or more public or

                                     15

<Page>

private sales. Each Holder through the Purchase Contract Agent agrees and
acknowledges that the Collateral is of a type customarily sold in a
recognized market and that, accordingly, no notice of intended disposition of
the Collateral need be given by the Collateral Agent.

            (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 Portfolio Interests or on account
of principal payments of any Pledged Treasury Securities as provided in Article
III hereof in satisfaction of the obligations of the Holder of Growth PRIDES of
which such Pledged Treasury Securities or the appropriate Applicable Ownership
Interest of the Treasury Portfolio, as applicable, is a part under the related
Purchase Contracts, the inability to make such payments shall constitute an
event of default hereunder and the Collateral Agent shall have and may exercise,
with reference to such Pledged Treasury Securities or such Pledged Portfolio
Interests, as applicable, and such obligations of such Holder, any and all of
the rights and remedies available to a secured party under the Code and the
TRADES Regulations after default by a debtor, and as otherwise granted herein or
under any other law.

            (c) Without limiting any rights or powers otherwise granted by this
Agreement to the Collateral Agent, the Collateral Agent is hereby irrevocably
authorized to receive and collect all payments of (i) the Stated Amount of or,
interest on, the Pledged Senior Notes, (ii) the principal amount at maturity of
the Pledged Treasury Securities or (iii) the Pledged Portfolio Interests,
subject, in each case, to the provisions of Article 3, and as otherwise granted
herein.

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

      Section 6.2 TAX EVENT REDEMPTION. Upon the occurrence of a Tax Event
Redemption prior to the Purchase Contract Settlement Date, the aggregate
Redemption Price payable on the Tax Event Redemption Date with respect to the
Pledged Senior Notes shall be delivered to the Collateral Agent by the Trustee
on or prior to 12:00 p.m., New York City time, by check or wire transfer in
immediately available funds to the Collateral Agent or such other account as may
be designated in writing by the Collateral Agent in exchange for the Pledged
Senior Notes. In the event the Collateral Agent receives such Redemption Price,
the Collateral Agent will, at the written direction of the Company, apply an
amount, out of such Redemption Price, equal to the aggregate Redemption Amount
with respect to the Pledged Senior Notes to purchase from the Quotation Agent
the Treasury Portfolio and promptly remit the remaining portion of such
Redemption Price to the Purchase Contract Agent for payment to the Holders of
Income PRIDES. The Collateral Agent shall Transfer (or cause to be transferred)
Portfolio Interests

                                     16

<Page>

representing 100% of the entire Treasury Portfolio or to the Collateral
Account pursuant to the Pledge hereunder, in substitution for the Pledged
Senior Notes. Thereafter, the Collateral Agent shall have such security
interests, rights and obligations with respect to the Portfolio Interests as
it had in respect of the Pledged Senior Notes as provided herein, and any
reference herein to the Senior Notes shall be deemed to be reference to such
Portfolio Interests, and any reference herein to interest on the Senior Notes
shall be deemed to be a reference to distributions on such Portfolio
Interests. During any period greater than one Business Day between the
receipt of the Redemption Price in Cash upon the Tax Event Redemption and the
payment of all or a portion thereof to the Quotation Agent for the purchase
of the Treasury Portfolio, as provided above, the Collateral Agent shall
promptly invest any such Cash in Permitted Investments. Upon receipt of the
Proceeds upon the maturity of such Permitted Investments on the date of the
purchase of the Treasury Portfolio as described above, the Collateral Agent
(i) shall pay such proceeds (and deliver any certified or cashiers' checks
received and any funds so wired) in an amount equal to the purchase price of
the Treasury Portfolio to the Quotation Agent and (ii) and shall distribute
any funds in respect of the interest earned from the Permitted Investments to
the Purchase Contract Agent for payment to the relevant Holders.

      Section 6.3 INITIAL REMARKETING. The Collateral Agent shall, by 10:00
a.m., New York City time, on the fourth Business Day immediately preceding
August 17, 2004, without any instruction from any Holder of Income PRIDES,
present the Pledged Senior Notes to the Remarketing Agent for remarketing.
Upon receiving such Pledged Senior Notes, the Remarketing Agent, pursuant to
the terms of the Remarketing Agreement, will use its reasonable efforts to
remarket such Pledged Notes on such date at a price of approximately 100.5%
(but not less than 100%) of the Treasury Portfolio Purchase Price. After
deducting as the Remarketing Fee an amount not exceeding 25 basis points
(0.25%) of the Treasury Portfolio Purchase Price from any amount of such
Proceeds in excess of the Treasury Portfolio Purchase Price, the Remarketing
Agent will remit the entire amount of the Proceeds of such remarketing to the
Collateral Agent on or prior to 12:00 p.m., New York City time, by check or
wire transfer in immediately available funds to the Collateral Account or
such other account and at such account as may be designated by the Collateral
Agent in exchange for the Pledged Senior Notes. In the event the Collateral
Agent receives such Proceeds, the Collateral Agent will, at the written
direction of the Company, apply an amount equal to the Treasury Portfolio
Purchase Price to purchase from the Quotation Agent the Portfolio Interests
and promptly remit the remaining portion of such Proceeds to the Purchase
Contract Agent for payment to the Holders of Income PRIDES. The Collateral
Agent shall Transfer the Portfolio Interests to the Collateral Account to
secure the obligation of all Holders of Income PRIDES to purchase Common
Stock of the Company under the Purchase Contracts constituting a part of such
Income PRIDES, in substitution for the Pledged Senior Notes. Thereafter the
Collateral Agent shall have such security interests, rights and obligations
with respect to the Portfolio Interests as it had in respect of the Pledged
Senior Notes as provided herein, and any reference herein to the Senior Notes
shall be deemed to be reference to such Portfolio Interests, and any
reference herein to interest on the Senior Notes shall be deemed to be a
reference to distributions on such Portfolio Interests. During any period
greater than one Business Day between the receipt of such Proceeds from the
Initial Remarketing and the payment of all or a portion thereof to the
Quotation Agent for the purchase of the Treasury Portfolio, as provided
above, the Collateral Agent (i) shall promptly invest any such Cash in
Permitted Investments. Upon receipt of the proceeds upon the maturity of such
Permitted Investments on the date of the purchase of the Treasury Portfolio
as described

                                     17
<Page>

above, the Collateral Agent shall pay such proceeds (and deliver any
certified or cashiers' checks received and any funds so wired) in an amount
equal to the purchase price of the Treasury Portfolio to the Quotation Agent
and (ii) and shall distribute any funds in respect of the interest earned
from the Permitted Investments to the Purchase Contract Agent for payment to
the relevant Holders.

      Section 6.4 SUBSTITUTIONS. Whenever a Holder has the right to
substitute Treasury Securities or Senior Notes (or Portfolio Interests), as
the case may be, for Collateral held by the Collateral Agent, such
substitution shall not constitute a novation of the security interest created
hereby.

                                   ARTICLE VII
                  Representations and Warranties; Covenants

      Section 7.1 REPRESENTATIONS AND WARRANTIES. The Holders from time to time,
acting through the Purchase Contract Agent as their attorney-in-fact (it being
understood that the Purchase Contract Agent shall not be liable for any
representation or warranty made by or on behalf of a Holder), hereby represent
and warrant to the Collateral Agent, which representations and warranties shall
be deemed repeated on each day a Holder Transfers Collateral that:

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

            (b) such Holder is the sole beneficial owner of the Collateral and,
      in the case of Collateral delivered in physical form, is the sole holder
      of such Collateral and is the sole beneficial owner of, or has the right
      to Transfer, the Collateral it Transfers to the Collateral Agent, free and
      clear of any security interest, lien, encumbrance, call, liability to pay
      money or other restriction other than the security interest and lien
      granted under Section 2.1 hereof;

            (c) upon the Transfer of the Collateral to the Collateral Account,
      the Collateral Agent, for the benefit of the Company, will have a valid
      and perfected first priority security interest therein (assuming that any
      central clearing operation or any Intermediary or other entity not within
      the control of the Holder involved in the Transfer of the Collateral,
      including the Collateral Agent, gives the notices and takes the action
      required of it hereunder and under applicable law for perfection of that
      interest and assuming the establishment and exercise of control pursuant
      to Section 2.2 hereof); and

            (d) the execution and performance by the Holder of its obligations
      under this Agreement will not result in the creation of any security
      interest, lien or other encumbrance on the Collateral other than the
      security interest and lien granted under Section 2.1 hereof or violate any
      provision of any existing law or regulation applicable to it or of any
      mortgage, charge, pledge, indenture, contract or undertaking to which it
      is a party or which is binding on it or any of its assets.

      Section 7.2 COVENANTS. The Holders from time to time, acting through the
Purchase Contract Agent as their attorney-in-fact (it being understood that the
Purchase Contract Agent

                                       18

<Page>

shall not be liable for any covenant made by or on behalf of a Holder),
hereby covenant to the Collateral Agent that for so long as the Collateral
remains subject to the Pledge:

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

            (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;
      and

            (c) if any Collateral is delivered to any Holder or to the Purchase
      Contract Agent, such Holder or the Purchase Contract Agent will deliver
      the sum to the Collateral Agent, properly indorsed when required, and in
      the form received.

                                  ARTICLE VIII
                              The Collateral Agent

      Section 8.1 APPOINTMENT, POWERS AND IMMUNITIES. The Collateral Agent
shall act as Agent for the Company hereunder with such powers as are
specifically vested in the Collateral Agent by the terms of this Agreement,
together with such other powers as are reasonably incidental thereto. Each of
the Collateral Agent, the Custodial Agent and the Securities Intermediary:
(a) shall have no duties or responsibilities except those expressly set forth
in this Agreement and no implied covenants or obligations shall be inferred
from this Agreement against any of them, nor shall any of them be bound by
the provisions of any agreement by any party hereto beyond the specific terms
hereof; (b) shall not be responsible for any recitals contained in this
Agreement, or in any certificate or other document referred to or provided
for in, or received by it under, this Agreement, the Income PRIDES, Growth
PRIDES or the Purchase Contract Agreement, or for the value, validity,
effectiveness, genuineness, enforceability or sufficiency of this Agreement
(other than as against the Collateral Agent), the Securities or the Purchase
Contract Agreement or any other document referred to or provided for herein
or therein or for any failure by the Company or any other Person (except the
Collateral Agent, the Custodial Agent or the Securities Intermediary, as the
case may be) to perform any of its obligations hereunder or thereunder or for
the perfection, priority or, except as expressly required hereby, maintenance
of any security interest created hereunder; (c) shall not be required to
initiate or conduct any litigation or collection proceedings hereunder
(except in the case of the Collateral Agent, pursuant to directions furnished
under Section 8.2 hereof, subject to Section 8.6 hereof); (d) shall not be
responsible for any action taken or omitted to be taken by it hereunder or
under any other document or instrument referred to or provided for herein or
in connection herewith or therewith, except for its own negligence, bad faith
or willful misconduct; and (e) shall not be required to advise any party as
to selling or retaining, or taking or refraining from taking any action with
respect to, the 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.

                                       19

<Page>

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

      Section 8.2 INSTRUCTIONS OF THE COMPANY. The Company shall have the
right, by one or more instruments in writing executed and delivered to the
Collateral Agent, the Custodial Agent or the Securities Intermediary, as the
case may be, to direct the time, method and place of conducting any
proceeding for the realization of any right or remedy available to the
Collateral Agent, or of exercising any power conferred on the Collateral
Agent, the Custodial Agent or the Securities Intermediary, as the case may
be, or to direct the taking or refraining from taking of any action
authorized by this Agreement; provided, however, that (i) such direction
shall not conflict with the provisions of any law or of this Agreement and
(ii) the Collateral Agent, the Custodial Agent and the Securities
Intermediary shall be adequately indemnified as provided herein. Nothing in
this Section 8.2 shall impair the right of the Collateral Agent in its
discretion to take any action or omit to take any action which it deems
proper and which is not inconsistent with such direction.

      Section 8.3 RELIANCE BY COLLATERAL AGENT. Each of the Securities
Intermediary, the Custodial Agent and the Collateral Agent shall be entitled
conclusively to rely upon any certification, order, judgment, opinion, notice
or other communication (including, without limitation, any thereof by
telephone or facsimile) believed by it in good faith to be genuine and
correct and to have been signed or sent by or on behalf of the proper Person
or Persons (without being required to determine the correctness of any fact
stated therein), and upon advice and statements of legal counsel and other
experts selected by the Collateral Agent, the Custodial Agent or the
Securities Intermediary, as the case may be. As to any matters not expressly
provided for by this Agreement, the Collateral Agent, the Custodial Agent and
the Securities Intermediary shall in all cases be fully protected in acting,
or in refraining from acting, hereunder in accordance with instructions given
by the Company in accordance with this Agreement.

      Section 8.4 RIGHTS IN OTHER CAPACITIES. The Collateral Agent, the
Custodial Agent and the Securities Intermediary and their affiliates may
(without having to account therefor to the Company) accept deposits from, lend
money to, make their investments in and generally engage in any kind of banking,
trust or other business with the Purchase Contract Agent, any Holder of Income
PRIDES or Growth PRIDES and any holder of Separate Senior Notes (and any of

be created in favor of any other Person, any security interest, lien or other

referred to or provided for herein or therein or to inspect the properties or
books of the Purchase Contract Agent or any Holder of Income PRIDES or Growth
PRIDES. The Collateral Agent, the Custodial Agent and the Securities
Intermediary shall not have any duty or responsibility to provide the Company
or the Remarketing Agent with any credit or other information concerning the
affairs, financial condition or business of the Purchase Contract Agent, any
Holder of Income PRIDES or Growth PRIDES or any holder of Separate Senior

Securities Intermediary or any of their respective affiliates.

      Section 8.6 COMPENSATION AND INDEMNITY. The Company agrees: (i) to pay
each of the Collateral Agent and the Custodial Agent from time to time such

Agent, the Custodial Agent and the Securities Intermediary for, and to hold
each of them harmless from and against, any loss, liability or reasonable
out-of-pocket expense incurred without negligence, willful misconduct or bad
faith on its part, arising out of or in connection with the acceptance or
administration of its powers and duties under this Agreement, including the
reasonable out-of-pocket costs and expenses (including reasonable fees and
expenses of counsel) of defending itself against any claim or liability in
connection with the exercise or performance of such powers and duties. The
Collateral Agent, the Custodial Agent and the Securities Intermediary shall
each promptly notify the Company of any third party claim which may give rise
to the indemnity hereunder and give the Company the opportunity to
participate in the defense of such claim with counsel reasonably satisfactory
to the indemnified party, and no such claim shall be settled without the
written consent of the Company, which consent shall not be unreasonably
withheld.

      Section 8.7 FAILURE TO ACT. In the event of any ambiguity in the
provisions of this Agreement or any dispute between or conflicting claims by or
among the parties hereto or any other Person with respect to any funds or
property deposited hereunder, the Collateral Agent and the Custodial Agent shall
be entitled, after prompt notice to the Company and the Purchase Contract Agent,
at its sole option, to refuse to comply with any and all claims, demands or
instructions with respect to such property or funds so long as such dispute or
conflict shall continue, and neither the Collateral Agent nor the Custodial
Agent shall be or become liable in any way to any of the parties hereto for its
failure or refusal to comply with such conflicting claims, demands or
instructions. The Collateral Agent and the Custodial Agent shall be entitled to
refuse to act until either (i) such conflicting or adverse claims or demands
shall have been finally determined by a court of competent jurisdiction or
settled by agreement between the conflicting parties as evidenced in a writing,
satisfactory to the Collateral Agent or the Custodial

                                       21

<Page>

Agent, as the case may be, or (ii) the Collateral Agent or the Custodial
Agent, as the case may be, shall have received security or an indemnity
reasonably satisfactory to the Collateral Agent or the Custodial Agent, as
the case may be, sufficient to save the Collateral Agent or the Custodial
Agent, as the case may be, harmless from and against any and all loss,
liability or reasonable out-of-pocket expense which the Collateral Agent or
the Custodial Agent, as the case may be, may incur by reason of its acting
without bad faith, willful misconduct or gross negligence. The Collateral
Agent or the Custodial Agent may in addition elect to commence an
interpleader action or seek other judicial relief or orders as the Collateral
Agent or the Custodial Agent, as the case may be, may deem necessary.
Notwithstanding anything contained herein to the contrary, neither the
Collateral Agent nor the Custodial Agent shall be required to take any action
that is in its opinion contrary to law or to the terms of this Agreement, or
which would in its opinion subject it or any of its officers, employees or
directors to liability.

      Section 8.8 RESIGNATION OF COLLATERAL AGENT. Subject to the appointment
and acceptance of a successor Collateral Agent or Custodial Agent as provided

time by giving not less than 20 days prior notice thereof to the Company and
the Purchase Contract Agent as attorney-in-fact for the Holders of Income
PRIDES or Growth PRIDES, (b) the Collateral Agent and the Custodial Agent may
be removed at any time by the Company and (c) if the Collateral Agent or the
Custodial 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 or the Custodial Agent may
be removed by the Purchase Contract Agent. The Purchase Contract Agent shall
promptly notify the Company of any removal of the Collateral Agent pursuant
to clause (c) of the immediately preceding sentence. Upon any such
resignation or removal, the Company shall have the right to appoint a
successor Collateral Agent or Custodial Agent, as the case may be. If no
successor Collateral Agent or Custodial Agent, as the case may be, shall have
been so appointed and shall have accepted such appointment within 30 days
after the retiring Collateral Agent's or Custodial Agent's giving of notice
of resignation or such removal, then the retiring Collateral Agent or
Custodial Agent, as the case may be, may, at the expense of the Company,
petition any court of competent jurisdiction for the appointment of a
successor Collateral Agent or Custodial Agent, as the case may be. Each of
the Collateral Agent and the Custodial Agent shall be a bank which has an
office in New York, New York with a combined capital and surplus of at least
$75,000,000. Upon the acceptance of any appointment as Collateral Agent or
Custodial Agent, as the case may be, hereunder by a successor Collateral
Agent or Custodial Agent, as the case may be, such successor shall thereupon
succeed to and become vested with all the rights, powers, privileges and
duties of the retiring Collateral Agent or Custodial Agent, as the case may
be, and the retiring Collateral Agent or Custodial Agent, as the case may be,
shall take all appropriate action to transfer any money and property held by
it hereunder (including the Collateral) to such successor. The retiring
Collateral Agent or Custodial Agent shall, upon such succession, be
discharged from its duties and obligations as Collateral Agent or Custodial
Agent hereunder. After any retiring Collateral Agent's or Custodial Agent's
resignation hereunder as Collateral Agent or Custodial Agent, the provisions
of this Section 8.8 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 or Custodial Agent. Any resignation or removal of the
Collateral Agent hereunder shall be deemed for all purposes of this Agreement
as the simultaneous resignation or removal of the Custodial Agent and the
Securities Intermediary.

      Section 8.9 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 8.9 shall be subject to prior consent of the Company, which consent
shall not be unreasonably withheld.

      Section 8.10 SURVIVAL. The provisions of this Article 8 shall survive
termination of this Agreement and the resignation or removal of the
Collateral Agent or the Custodial Agent.

      Section 8.11 EXCULPATION. Anything in this Agreement to the contrary
notwithstanding, in no event shall any of the Collateral Agent, the Custodial
Agent or the Securities Intermediary or their officers, employees or agents
be liable under this Agreement to any third party for indirect, special,
punitive, or consequential loss or damage of any kind whatsoever, including
lost profits, whether or not the likelihood of such loss or damage was known
to the Collateral Agent, the Custodial Agent or the Securities Intermediary,
or any of them, incurred without any act or deed that is found to be
attributable to gross negligence, bad faith or willful misconduct on the part
of the Collateral Agent, the Custodial Agent or the Securities Intermediary.
