                  Barney Inc., as underwriters therein.

                  Section 1.2       Compliance Certificates and Opinions.

                  Except as otherwise expressly provided by this Agreement, upon
any application or request by the Company to the Agent to take any action under
any provision of this Agreement, the Company shall furnish to the Agent an
Officer's Certificate stating that all conditions precedent, if any, provided
for in this Agreement relating to the proposed action have been complied with
and, if reasonably requested by the Agent, an Opinion of Counsel addressed to

precedent, if any, have been complied with, except that in the case of any such
application or request as to which the furnishing of such documents is
specifically required by any provision of this Agreement relating to such
particular application or request, no additional certificate or opinion need be
furnished.

                  Every certificate or opinion with respect to compliance with a
condition or covenant provided for in this Agreement shall include:

                  (1) a statement that each Person signing such certificate or

                  In any case where several matters are required to be certified
by, or covered by an opinion of, any specified Person, it is not necessary that
all such matters be certified by, or covered by the opinion of, only one such
Person, or that they be so certified or covered by only one document, but one
such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

                  Any certificate or opinion of the Company may be based,
insofar as it relates to legal matters, upon a certificate or opinion of, or
representations by, counsel, unless the Company knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, the Company stating that the information with respect to
such factual matters is in the possession of the Company unless the Person
giving such certificate or Opinion of Counsel knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to such matters are erroneous.

                  Where any Person is required to make, give or execute two or
more applications, requests, consents, certificates, statements, opinions or
other instruments under this Agreement, they may, but need not, be consolidated
and form one instrument.

                  Section 1.4       Acts of Holders; Record Dates.

                  (a) Any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Agreement to be given or taken
by Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Agent and, where it is hereby expressly required, to the Company. Such
instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Agreement and (subject to Section 7.1 hereof) conclusive in favor of the Agent
and the Company, if made in the manner provided in this Section 1.4.

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

                  (c) The ownership of Securities shall be proved by the
Corporate Units Register or the Treasury Units Register, as the case may be.

                  (d) Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Certificate shall bind every
future Holder of the same Certificate and the Holder of every Certificate issued
upon the registration of transfer thereof or in exchange therefor or in lieu


                                      -16-

thereof in respect of anything done, omitted or suffered to be done by the Agent
or the Company in reliance thereon, whether or not notation of such action is
made upon such Certificate.

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

                  With respect to any record date set pursuant to this Section
1.4, the Company may designate any date as the "Expiration Date" and from time
to time may change the Expiration Date to any earlier or later day; provided
that no such change shall be effective unless notice of the proposed new
Expiration Date is given to the Agent in writing, and to each Holder of
Securities in the manner set forth in Section 1.6 hereof, 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 1.4, the Company shall be deemed
to have initially designated the 180th day after such record date as the
Expiration Date with respect thereto, subject to its right to change the
Expiration Date as provided in this paragraph. Notwithstanding the foregoing, no
Expiration Date shall be later than the 180th day after the applicable record
date.

                  Section 1.5       Notices.

                  Any request, demand, authorization, direction, instruction,

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

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

                  Section 1.7       Effect of Headings and Table of Contents.

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

                  All covenants and agreements in this Agreement by the Company
shall bind its successors and assigns, whether so expressed or not.

                  Section 1.9       Separability Clause.

                  In case any provision in this Agreement or in the Securities
shall be invalid, illegal or unenforceable, then, to the extent permitted by
law, the validity, legality and enforceability of the remaining provisions
hereof and thereof shall not in any way be affected or impaired thereby.

                  Section 1.10      Benefits of Agreement.

                  Nothing in this Agreement or in the Securities, express or
implied, shall give to any Person, other than the parties hereto and their
successors hereunder and, to the extent provided hereby, the Holders, any
benefits or any legal or equitable right, remedy or claim under this Agreement.
The Holders from time to time shall be beneficiaries of this Agreement and shall
be bound by all of the applicable terms and conditions hereof and of the
Securities evidenced by their Certificates by their acceptance of delivery of
such Certificates.

                  Section 1.11      Governing Law.

CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK.

                  Section 1.12      Legal Holidays.

                  In any case where any Purchase Contract Settlement Date or any
Early Settlement Date shall not be a Business Day, then (notwithstanding any
other provision of this Agreement, the Corporate Unit Certificates or the
Treasury Unit Certificates), the Purchase Contracts shall not be performed on
such date, but the Purchase Contracts shall be performed on the immediately
following Business Day with the same force and effect as if performed on the
Purchase Contract Settlement Date or Early Settlement Date, as applicable.

                  In any case where the Payment Date shall not be a Business
Day, then (notwithstanding any other provision of this Agreement, the Corporate
Unit Certificates or the Treasury Unit Certificates), the Contract Adjustment
Payment shall not be made on such date, but shall be made on the immediately
following Business Day with the same force and effect as if made on the Payment
Date, provided that no interest shall accrue or be payable by the Company or to
any Holder for the period from and after any such Payment Date unless there
shall be a default in the payment due on such next succeeding Business Day.

                  This Agreement may be executed in any number of counterparts
by the parties hereto on separate counterparts, each of which, when so executed

the Collateral Agent) to act as its agent in performing its obligations and in
accepting and enforcing performance of the obligations of the Agent and the
Holders, under this Agreement and the Purchase Contracts, by giving notice of
such appointment in the manner provided in Section 1.5 hereof. Any such
appointment shall not relieve the Company in any way from its obligation
hereunder.

                  Section 1.16      No Waiver.

                  No failure on the part of the Company, the Agent, the
Collateral Agent, the Securities Intermediary or any of their respective agents
to exercise, and no course of dealing with respect to, and no delay in
exercising, any right, power or remedy hereunder shall operate as a waiver
thereof; nor shall any single or partial exercise by the Company, the Agent, the
Collateral Agent, the Securities Intermediary or any of their respective agents
of any right, power or remedy hereunder preclude any further exercise thereof or
the exercise of any right, power or remedy. The remedies herein are cumulative
and are not exclusive of any remedies provided by law.

                                 THE SECURITIES

                  Section 3.1       Title and Terms; Denominations.

                  The aggregate number of Corporate Units and Treasury Units
evidenced by Certificates authenticated, executed on behalf of the Holders and
delivered hereunder is limited to 8,855,000, except for Certificates
authenticated, executed and delivered upon registration of, transfer of, in
exchange for, or

                                      -21-

in lieu of, other Certificates pursuant to Section 3.4, 3.5, 3.9, 3.10, 3.13,
3.14, 5.7(b)(2), 5.10 or 8.5 hereof.

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

                  Section 3.2 Rights and Obligations Evidenced by the
Certificates.

                  Each Corporate Unit Certificate shall evidence the number of
Corporate Units specified therein, with each such Corporate Unit representing
the ownership by the Holder thereof of a beneficial interest in a Note or the
Applicable Ownership Interest in the Treasury Portfolio, as the case may be,
subject to the Pledge of such Note or the Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, by such Holder pursuant to the Pledge
Agreement, and the rights and obligations of the Holder thereof and the Company
under one Purchase Contract. The Agent as attorney-in-fact for, and on behalf
of, the Holder of each Corporate Unit shall pledge, pursuant to the Pledge
Agreement, the Note or the Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, forming a part of such Corporate Unit, to the
Collateral Agent and grant to the Collateral Agent a security interest in the
right, title, and interest of such Holder in such Note or the Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, for the
benefit of the Company, to secure the obligation of the Holder under each
Purchase Contract to purchase the shares of Common Stock.

                  Each Treasury Unit Certificate shall evidence the number of
Treasury Units specified therein, with each such Treasury Unit representing the
ownership by the Holder thereof of a 1/20, or 5%, undivided beneficial ownership
interest in a Treasury Security with 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 the rights and obligations of the Holder thereof
and the Company under one Purchase Contract. The Agent as attorney-in-fact for,
and on behalf of, the Holder of each Treasury Unit shall pledge, pursuant to the
Pledge Agreement, the Treasury Security to the Collateral Agent and grant to the
Collateral Agent a security interest in the right, title and interest of such
Holder in such Treasury Security, for the benefit of the Company, to secure the
obligation of the Holder under each Purchase Contract to purchase the Common
Stock of the Company.

                  Prior to the purchase of shares of Common Stock under each
Purchase Contract, such Purchase Contract shall not entitle the Holder of a
Security to any rights of a holder of shares of Common Stock, including, without
limitation, the right to vote or receive any dividends or other payments or to
consent or to receive notice as a shareholder in respect of the meetings of
shareholders or for the election of directors of the Company or for any other
matter, or any other rights whatsoever as a shareholder of the Company.

                  Section 3.3 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.


                                      -22-

                  The Certificates shall be executed on behalf of the Company by
(i) any one of its Chairman of the Board, its Chief Executive Officer, its
President, an Executive Vice President or a Senior Vice President and (ii) any
one of its Treasurer or one of its Assistant Treasurers or its Secretary or one
of its Assistant Secretaries. 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.

                  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 that 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 Corporate Units or
Treasury Units 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 or the New York 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
Corporate Units or Treasury Units, as the case may be, as the temporary
Certificate or Certificates so surrendered. Until so exchanged, the temporary
Certificates shall in all respects evidence the same benefits and the same
obligations with respect to the Corporate Units or Treasury Units, as the case
may be, evidenced thereby as definitive Certificates.


                                      -23-

                  Section 3.5 Registration; Registration of Transfer and
Exchange.

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

                  Upon surrender for registration of transfer of any Certificate
at the Corporate Trust Office or the New York 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 Corporate
Units or Treasury Units, as the case may be.

                  At the option of the Holder, Certificates may be exchanged for
other Certificates, of any authorized denominations and evidencing a like number
of Corporate Units or Treasury Units, as the case may be, upon surrender of the
Certificates to be exchanged at the Corporate Trust Office or the New York
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 that 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
Corporate Units or Treasury Units, as the case may be, and be entitled to the
same benefits and subject to the same obligations, under this Agreement as the
Corporate Units or Treasury Units, as the case may be, evidenced by the
Certificate surrendered upon such registration of transfer or exchange.

                  Every Certificate presented or surrendered for registration of
transfer or 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 3.4, 3.6, 3.9 and 8.5 hereof 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 3.5 and receipt of appropriate registration or transfer
instructions from such Holder, the Agent shall (i) if the Purchase Contract
Settlement Date has occurred, deliver (or request the Company to deliver) the
shares of Common Stock issuable in respect of the Purchase Contracts forming a
part of the Securities evidenced by such Certificate (together with any cash or
other property to which the Holder is entitled), or (ii) if a Termination Event
shall have occurred prior to the Purchase

                                      -24-

Contract Settlement Date, transfer the Notes, the appropriate Applicable
Ownership Interest in the Treasury Portfolio or the Treasury Securities, as the
case may be, evidenced thereby, in each case subject to the applicable
conditions and in accordance with the applicable provisions of Article V hereof.

                  Notwithstanding anything in this Agreement to the contrary, no
transfer by any Holder to any Person other than the Company of any Corporate
Unit, Treasury Unit or Note may be made or will be recognized unless such
instrument has been surrendered and accepted for registration of transfer in
accordance with the provisions of this Section 3.5, or unless such transfer is
effectuated through the book-entry system described in Section 3.6 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 will receive
a definitive Certificate representing such Beneficial Owner's interest in such
Global Certificate, except as provided in Section 3.9 hereof. 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 hereof:

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

                  (b) the Company and the Agent 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
hereof conflict with any other provisions of this Agreement, the provisions of
this Section 3.6 hereof 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 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 Agent shall, except as set forth herein,
have no obligations to the Beneficial Owners.


                                      -25-

                  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 hereof or (ii) there shall have occurred and be continuing a default
by the Company in respect of its obligations under one or more Purchase
Contracts, or the Indenture, 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.

                  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
Corporate Units or Treasury Units, 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 protected 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
Corporate Units or Treasury Units, as the case may be, and bearing a Certificate
number not contemporaneously outstanding.

                  Notwithstanding the foregoing, the Company shall not be
obligated to execute and deliver to the 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 3.10 and receipt of appropriate
registration or transfer instructions from such Holder, the Agent shall (i) if
the Purchase Contract Settlement Date has occurred, deliver (or request the
Company to deliver) the shares of Common Stock issuable in respect of the
Purchase Contracts forming a part of the Securities evidenced by such
Certificate (together with any cash or other property to which the Holder is
entitled), or (ii) if a Termination Event shall have occurred prior to the
Purchase Contract Settlement Date, transfer the Notes, the appropriate
Applicable Ownership Interest in the Treasury Portfolio or the Treasury
Securities, as the case may be, evidenced thereby, in each case subject to the
applicable conditions and in accordance with the applicable provisions of
Article V hereof.


                                      -26-

                  Upon the issuance of any new Certificate under this Section
3.10, 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 reasonable fees and
expenses of the Agent) connected therewith.

                  Every new Certificate issued pursuant to this Section 3.10 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 3.10 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 Corporate Units or Treasury Units evidenced thereby, for the purpose of
(subject to any applicable Record Date) receiving interest on the Notes or on
the maturing quarterly interest strips of the Treasury Portfolio, as applicable,
receiving payments of Contract Adjustment Payments (if any), for the performance
of the Purchase Contracts and for all other purposes whatsoever, whether or not
any interest on the 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. None of
the Company, the Agent nor any agent of the Company or the Agent will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests of a Global
Certificate or maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

                  Section 3.12      Cancellation.

                  All Certificates surrendered for delivery of shares of Common
Stock on or after the Purchase Contract Settlement Date, upon the transfer of
Notes, the appropriate Applicable Ownership Interest in the Treasury Portfolio
or Treasury Securities, as the case may be, after the occurrence of a
Termination Event or pursuant to an Early Settlement, or upon the registration
of a transfer or exchange of a Security, or a Collateral Substitution or the
reestablishment of a Corporate Unit or Treasury Unit 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

                                      -27-

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 3.12, except as expressly permitted by this Agreement.
All cancelled Certificates held by the Agent shall be disposed of by the Agent
in its customary manner.

                  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 Treasury Units.

                  Subject to the conditions set forth in this Agreement, a
Holder may separate the Notes or the appropriate Applicable Ownership Interest
in the Treasury Portfolio, as applicable, from the related Purchase Contracts in
respect of a Corporate Unit by substituting for such Notes or the appropriate
Applicable Ownership Interest in the Treasury Portfolio, as the case may be,
Treasury Securities in an aggregate principal amount of such Notes or the
appropriate Applicable Ownership Interest (as specified in clause (i) of the
definition of such term) in the Treasury Portfolio, as applicable (a "Collateral
Substitution"), at any time from and after the date of this Agreement and prior
to the seventh Business Day immediately preceding the Purchase Contract
Settlement Date in the case of the 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 in 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 Notes comprising part of such Corporate Units or the appropriate
Applicable Ownership Interest (as specified in clause (i) of the definition of
such term) in the Treasury Portfolio comprising part of such Corporate Unit, as
the case may be, and (b) transferring the related Corporate Units 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 Notes or the appropriate Applicable Ownership
Interest in the Treasury Portfolio, as the case may be, underlying such
Corporate Units, whereupon the Agent shall promptly give such instruction to the
Collateral Agent, substantially in the form of Exhibit C hereto. Notwithstanding
the foregoing, a Holder may not separate the Notes or the appropriate Applicable
Ownership Interest in the Treasury Portfolio, as applicable, from the related
Purchase Contracts in respect of the Corporate Units held by such Holder during
the period commencing on the fourth Business Day immediately prior to the
Initial Remarketing Date (and, upon a Failed Initial Remarketing, prior to the
Secondary Remarketing Date) and ending on the fourth Business Day following the
Initial Remarketing Date (and, upon a Failed Initial Remarketing, following the
Secondary Remarketing Date). 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, Notes or the appropriate
Applicable Ownership Interest in the Treasury Portfolio, as the case may be,
having the appropriate aggregate principal amount in the case of such Notes or
the appropriate Applicable Ownership Interest in 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 Corporate Units;


                                      -28-

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

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

                  Holders who elect to separate the Notes or the appropriate
Applicable Ownership Interest in the Treasury Portfolio, as the case may be,
from the related Purchase Contract and to substitute Treasury Securities for
such Notes or the appropriate Applicable Ownership Interest in 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 20 Corporate Units if Treasury Securities are being substituted for
the Notes, or (ii) only in integral multiples of 32,000 Corporate Units if
Treasury Securities are being substituted for the appropriate Applicable
Ownership Interest in the Treasury Portfolio.

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

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

                  Section 3.14      Reestablishment of Corporate Units.

                  Subject to the conditions set forth in this Agreement, a
Holder of a Treasury Unit may recreate Corporate Units at any time (i) prior to
the seventh Business Day immediately preceding the Purchase Contract Settlement
Date, if a Tax Event Redemption, a Successful Initial Remarketing or a
Successful Secondary 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, a Successful Initial Remarketing or a Successful
Secondary Remarketing has occurred and an Applicable Ownership Interest in the
Treasury Portfolio has become a component of the Corporate Units, in each case
by (a) depositing with the Collateral Agent Notes or the appropriate Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, having an
aggregate principal amount in the case of the Notes, or

                                      -29-

an appropriate Applicable Ownership Interest in the Treasury Portfolio, as the
case may be, equal to the aggregate principal amount of the Treasury Securities
comprising part of the Treasury Units and (b) transferring the related Treasury
Units 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 Notes or the appropriate Applicable Ownership Interest in 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 Treasury Units, whereupon the Agent shall promptly give such
instruction to the Collateral Agent, substantially in the form of Exhibit C
hereto. Notwithstanding the foregoing, a Holder may not reestablish Corporate
Units during the period commencing on the fourth Business Day immediately prior
the Initial Remarketing Date (and, upon a Failed Initial Remarketing, prior to
the Secondary Remarketing Date) and ending on the fourth Business Day following
the Initial Remarketing Date (and, upon a Failed Initial Remarketing, following
the Secondary Remarketing Date). Upon receipt of the Notes or the appropriate
Applicable Ownership Interest in 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 Treasury Units;

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

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

                  Holders who elect to reestablish Corporate Units shall be
responsible for any fees or expenses (including, without limitation, fees and
expenses payable to the Collateral Agent for its services as Collateral Agent)
in respect of the reestablishment and the Company shall not be responsible for
any such fees.

                  Holders of Treasury Units may reestablish Corporate Units in
integral multiples of 20 Treasury Units for the same multiple of 20 Corporate
Units if a Tax Event Redemption, a Successful Initial Remarketing or a
Successful Secondary Remarketing has not occurred, and in integral multiples of
32,000 Treasury Units for 32,000 Corporate Units if a Tax Event Redemption, a
Successful Initial Remarketing or a Successful Secondary Remarketing has
occurred.

                  In the event a Holder re-establishing Corporate Units pursuant
to this Section 3.14 fails to effect a book-entry transfer of the Treasury Units
or fails to deliver a Treasury Unit Certificate(s) to the Agent after depositing
Notes or the appropriate Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, with the Collateral Agent, the Treasury
Securities constituting a part of such Treasury Units shall be held in the name
of the Agent or its nominee in trust for the benefit of such Holder, until such
Treasury Units are so transferred or the Treasury Unit Certificate is so
delivered, as the case may be, or, with respect to a Treasury Unit Certificate,
such Holder provides evidence satisfactory to the Company and the Agent that
such Treasury Unit 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 Treasury Unit remains in effect, such Treasury
Unit shall not be separable into its constituent parts and

                                      -30-

the rights and obligations of the Holder of such Treasury Unit in respect of the
Treasury Security and Purchase Contract comprising such Treasury Unit may be
acquired, and may be transferred and exchanged, only as a Treasury Unit.

                  Section 3.15 Transfer of Collateral upon Occurrence of
Termination Event.

                  Upon the occurrence of a Termination Event and the transfer to
the Agent of the Notes, the appropriate Applicable Ownership Interest in the
Treasury Portfolio or the Treasury Securities, as the case may be, underlying
the Corporate Units and the Treasury Units pursuant to the terms of the Pledge
Agreement, the Agent shall request transfer instructions with respect to such
Notes or the appropriate Applicable Ownership Interest in 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 Corporate Units
Register or the Treasury Units Register, as the case may be. Upon book-entry
transfer of the Corporate Units or Treasury Units or delivery of a Corporate
Unit Certificate or a Treasury Unit Certificate to the Agent with such transfer
instructions, the Agent shall transfer the Notes, the Applicable Ownership
Interest in the Treasury Portfolio or Treasury Securities, as the case may be,
underlying such Corporate Units or Treasury Units, as the case may be, to such
Holder by book-entry transfer, or other appropriate procedures, in accordance
with such instructions; provided that, to the extent that a Holder of Corporate
Units or Treasury Units would otherwise be entitled to receive less than $1,000
principal amount at maturity of the 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 Corporate Units or Treasury
Units fails to effect such transfer or delivery, the Notes, the appropriate
Applicable Ownership Interest in the Treasury Portfolio or Treasury Securities,
as the case may be, underlying such Corporate Units or Treasury Units, as the
case may be, and any distributions thereon, shall be held in the name of the
Agent or its nominee in trust for the benefit of such Holder, until such
Corporate Units or Treasury Units are transferred or the Corporate Unit
Certificate or Treasury Unit Certificate is surrendered or such Holder provides
satisfactory evidence that such Corporate Unit Certificate or Treasury Unit
Certificate has been destroyed, lost or stolen, together with any indemnity that
may be required by the Agent and the Company.

                  Section 3.16      No Consent to Assumption.

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

                  Section 3.17      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 of redemption 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 changes in the "CUSIP" numbers.


                                      -31-

                                   ARTICLE IV

                   THE NOTES AND APPLICABLE OWNERSHIP INTEREST

                            IN THE TREASURY PORTFOLIO

                  Section 4.1 Interest and Other Payments; Rights to Payments
Preserved; Rate Reset; Notice.

                  Any distribution on any 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
Indenture Trustee or from the Collateral Agent as provided by the terms of the
Pledge Agreement, be paid to the Person in whose name the Corporate Unit
Certificate (or one or more Predecessor Corporate Unit Certificates) of which
such Note or the appropriate Applicable Ownership Interest in the Treasury
Portfolio, as the case may be, is a part is registered at the close of business
on the Record Date for such Payment Date.

                  Each Corporate Unit Certificate evidencing Notes or the
appropriate Applicable Ownership Interest in the Treasury Portfolio delivered
under this Agreement upon registration of transfer of or in exchange for or in
lieu of any other Corporate Unit Certificate shall carry the rights to accrued
and unpaid distributions, and other amounts that are to accrue, which were or
will be carried by the Notes or the appropriate Applicable Ownership Interest in
the Treasury Portfolio underlying such other Corporate Unit Certificate.

                  In the case of any Corporate Units 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
Notes or distributions on the appropriate Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, underlying such Corporate Units
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 Corporate Unit 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 Corporate Units 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 Notes or on the appropriate Applicable Ownership Interest in 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 Corporate Units; provided that to the
extent that such Holder continues to hold the separated Notes that formerly
comprised a part of such Holder's Corporate Units, such Holder shall be entitled
to receive any payments made on such separated Notes.

                  The applicable Coupon Rate on the Notes on and after May 16,
2005 will be reset on the Initial Remarketing Date to the applicable Reset Rate
(such Reset Rate to be in effect on and after May 16, 2005), except in the event
of a Failed Initial Remarketing. In the event of a Failed Initial Remarketing,
the applicable Coupon Rate on the Notes outstanding on and after July 1, 2005
will be reset

                                      -32-

on the Secondary Remarketing Date to the applicable Reset Rate (such Reset Rate
to be in effect on and after July 1, 2005), except in the event of a Failed
Secondary Remarketing. In the event of a Failed Secondary Remarketing, the
applicable Coupon Rate on the Notes outstanding on and after the Purchase
Contract Settlement Date will be reset on the Final Remarketing Date to the
applicable Reset Rate (such Reset Rate to be in effect on and after the Purchase
Contract Settlement Date), except in the event of a Failed Final Remarketing. On
the applicable Reset Announcement Date, the Reset Spread and the Two-Year
Benchmark Treasury, Two and One-Quarter Benchmark Treasury or Two and One-Eighth
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 Notes will be notified of such Reset Spread
and Two-Year Benchmark Treasury, Two and One-Quarter Benchmark Treasury or Two
and One-Eighth Benchmark Treasury, as applicable, by the Company. Such notice
shall be sufficiently given to Holders of Notes if published in an Authorized
Newspaper in The City of New York.

                  Not later than seven calendar days nor more than fifteen
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 Corporate Units or Treasury Units of such Reset
Announcement Date and, in the case of a Final Remarketing, the procedures to be
followed by Holders of Corporate Units 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 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 Notes are entitled to vote or upon any solicitation of consents,
waivers or proxies of holders of Notes, the Agent shall, as soon as practicable
thereafter, mail to the Holders of Corporate Units a notice (prepared by the
Company) (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 Notes entitled to vote) shall be entitled to
instruct the Agent as to the exercise of the voting rights pertaining to the
Notes underlying their Corporate Units and (c) stating the manner in which such
instructions may be given. Upon the written request of the Holders of Corporate
Units on such record date, the Agent shall endeavor insofar as practicable to
vote or cause to be voted, in accordance with the instructions set forth in such
requests, the maximum number of Notes as to which any particular voting
instructions are received. In the absence of specific instructions from the
Holder of a Corporate Unit, the Agent shall abstain from voting the Notes
underlying such Corporate Units. The Company hereby agrees, if applicable, to
solicit Holders of Corporate Units to timely instruct the Agent in order to
enable the Agent to vote such Notes.

                  Section 4.3       Tax Event Redemption.

                  Upon the occurrence of a Tax Event Redemption prior to May 16,
2005, or, in the event of a Failed Initial Remarketing but a Successful
Secondary Remarketing prior to July 1, 2005 or, in the event of a Failed
Secondary Remarketing, prior to the Purchase Contract Settlement Date, pursuant
to the terms of the Pledge Agreement, the Collateral Agent will apply an amount
equal to the aggregate Redemption Amount for the Notes that are components of
Corporate Units, plus accrued and unpaid interest on such Notes with respect to
any Interest Payment Date on or prior to the date of redemption, to

                                      -33-

purchase on behalf of the Holders of Corporate Units the Treasury Portfolio and
promptly remit the remaining portion of such Redemption Amount to the Agent for
payment to the Holders of such Corporate Units. The Treasury Portfolio will be
substituted for the pledged 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 a Corporate Unit to purchase the Common Stock of the Company
under the Purchase Contract constituting a part of such Corporate Units.
Following the occurrence of a Tax Event Redemption prior to May 16, 2005 or, in
the event of a Failed Initial Remarketing but a Successful Secondary
Remarketing, prior to July 1, 2005 or, in the event of a Failed Secondary
Remarketing, prior to the Purchase Contract Settlement Date, the Holders of
Corporate Units and the Collateral Agent shall have such security interests,
rights and obligations with respect to the Treasury Portfolio as the Holders of
Corporate Units and the Collateral Agent had in respect of the Notes, as the
case may be, subject to the Pledge thereof as provided in Sections 2, 3, 4, 5
and 6 of the Pledge Agreement, and any reference herein or in the Certificates
to the Note shall be deemed to be a reference to such Treasury Portfolio and any
reference herein or in the Certificates to interest on the Notes shall be deemed
to be a reference to corresponding distributions on the Treasury Portfolio. The
Company may cause to be made in any Corporate Unit Certificates thereafter to be
issued such change in phraseology and form (but not in substance) as may be
appropriate to reflect the substitution of the Treasury Portfolio for Notes as
collateral.

                  Section 4.4       CUSIP Numbers.

                  The Company in issuing the Notes may use "CUSIP" numbers (if
then generally in use), and, if so, the Indenture Trustee shall use "CUSIP"
numbers in notices of redemption 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 Notes or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Notes, and any such redemption shall not be affected by
any defect in or omission of such numbers. The Company will promptly notify the
Indenture Trustee and the Agent of any changes in the "CUSIP" numbers.

                                    ARTICLE V

                             THE PURCHASE CONTRACTS

                  Section 5.1       Purchase of Shares of Common Stock.

                  Each Purchase Contract shall obligate the Holder of the
related Security to purchase, and the Company to sell, on the Purchase Contract
Settlement Date at a price equal to the Stated Amount (the "Purchase Price"), a
number of newly issued shares of Common Stock equal to the Settlement Rate
unless an Early Settlement has occurred in accordance with Section 5.7(b)(2) or
Section 5.10 hereof, or, 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
$29.04 (the "Threshold Appreciation Price"), 1.7218 shares of Common Stock per
Purchase Contract, which is equal to the Stated Amount divided by the Threshold
Appreciation Price, (b) if the Applicable Market Value is less than the
Threshold Appreciation Price but is greater than $24.20 (the "Reference Price"),
the number of shares of Common Stock per Purchase Contract equal to the Stated
Amount divided by the Applicable Market Value and (c) if the Applicable Market
Value is less than or equal to the Reference Price, 2.0661 shares of Common
Stock per Purchase Contract, in each case subject to adjustment as provided in
Section 5.7 (and

                                      -34-

in each case rounded upward or downward to the nearest 1/10,000th of a share).
As provided in Section 5.11 hereof, no fractional shares of Common Stock will be
issued upon settlement of Purchase Contracts.

                  (a) Subject to Section 5.3 herein, the Company shall pay, on
each Payment Date, the Contract Adjustment Payments, if any, payable in respect
of each Purchase Contract to the Person in whose name a Certificate (or one or
more Predecessor Certificates) is registered at the close of business on the
Record Date next preceding such Payment Date in such coin or currency of the
United States as at the time of payment shall be legal tender for payments. The
Contract Adjustment Payments, if any, will be payable at the New York Office
maintained for that purpose or, at the option of the Company, by check mailed to
the address of the Person entitled thereto at such Person's address as it
appears on the Corporate Units Register or the Treasury Units Register or by
wire transfer to the account designated by a prior written notice by such
Person.

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

                  Each Certificate delivered under this Agreement upon

Purchase Contracts underlying such other Certificates.

                  Subject to Section 5.7(b)(2) and Section 5.10 hereof, in the
case of any Security with respect to which Early Settlement of the underlying
Purchase Contract is effected on an Early Settlement Date, or in respect of
which Cash Settlement of the underlying Purchase Contract is effected on the
Business Day immediately preceding the Purchase Contract Settlement Date, or
with respect to which a Collateral Substitution or an establishment or
re-establishment of Corporate Units pursuant to Section 3.14 hereof is effected,
in each case on a date that is after any Record Date and on or prior to the next
succeeding Payment Date, Contract Adjustment Payments on the Purchase Contracts
underlying such Securities otherwise payable on such Payment Date shall be
payable on such Payment Date notwithstanding such Cash Settlement, Early
Settlement, Collateral Substitution or establishment or re-establishment of
Corporate Units, and such Contract Adjustment Payments shall be paid to the
Person in whose name the Certificate evidencing such Security (or one or more
Predecessor Certificates) is registered at the close of business on such Record
Date.

                  Except as otherwise expressly provided in the immediately
preceding sentence, in the case of any Security 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 on an Early Settlement Date, as the case may be, or with respect to which a
Collateral Substitution or an establishment or re-establishment of Corporate
Units has been effected, Contract Adjustment Payments, if any (including any
Deferred Contract Adjustment Payments), that would otherwise be payable after
the Purchase Contract Settlement Date or Early Settlement Date, Collateral
Substitution or such establishment or re-establishment with respect to such
Purchase Contract shall not be payable.


                                      -36-



         (b) The Company's obligations with respect to Contract Adjustment
Payments, if any, will be subordinated and junior in right of payment to the
Company's obligations under any Senior Indebtedness.

         (c) In the event (x) of any payment by, or distribution of assets of,
the Company of any kind or character, whether in cash, property or securities,
to creditors upon any dissolution, winding-up, liquidation or reorganization of
the Company, whether voluntary or involuntary or in bankruptcy, insolvency,
receivership or other proceedings, or (y) subject to the provisions of Section
5.2(e) below, that (i) a default shall have occurred and be continuing with
respect to the payment of principal, interest or any other monetary amounts due
and payable on any Senior Indebtedness and such default shall have continued
beyond the period of grace, if any, specified in the instrument evidencing such
Senior Indebtedness (and the Agent shall have received written notice thereof
from the Company or one or more holders of Senior Indebtedness or their
representative or representatives or the trustee or trustees under any indenture
pursuant to which any such Senior Indebtedness may have been issued), or (ii)
the maturity of any Senior Indebtedness shall have been accelerated because of a
default in respect of such Senior Indebtedness (and the Agent shall have
received written notice thereof from the Company or one or more holders of
Senior Indebtedness or their representative or representatives or the trustee or
trustees under any indenture pursuant to which any such Senior Indebtedness may
have been issued), then:

                  (i) the holders of all Senior Indebtedness shall first be
         entitled to receive, in the case of clause (x) above, payment in full
         of all amounts due or to become due upon all Senior Indebtedness and,
         in the case of subclauses (i) and (ii) of clause (y) above, payment of
         all amounts due thereon, or provision shall be made for such payment in
         money or money's worth, before the Holders of any of the Securities are
         entitled to receive any Contract Adjustment Payments on the Purchase
         Contracts underlying the Securities;

                  (ii) any payment by, or distribution of assets of, the Company
         of any kind or character, whether in cash, property or securities, to
         which the Holders of any of the Securities would be entitled except for
         the provisions of Sections 5.2(b) through (n), including any such
         payment or distribution which may be payable or deliverable by reason
         of the payment of any other indebtedness of the Company being
         subordinated to the payment of such Contract Adjustment Payments on the
         Purchase Contracts underlying the Securities, shall be paid or
         delivered by the Person making such payment or distribution, whether a
         trustee in bankruptcy, a receiver or liquidating trustee or otherwise,
         directly to the holders of such Senior Indebtedness or their
         representative or representatives or to the trustee or trustees under
         any indenture under which any instruments evidencing any of such Senior
         Indebtedness may have been issued, ratably according to the aggregate
         amounts remaining unpaid on account of such Senior Indebtedness held or
         represented by each, to the extent necessary to make payment in full of
         all Senior Indebtedness remaining unpaid after giving effect to any
         concurrent payment or distribution (or provision therefor) to the
         holders of such Senior Indebtedness, before any payment or distribution
         is made of such Contract Adjustment Payments to the Holders of such
         Securities; and

                  (iii) in the event that, notwithstanding the foregoing, any
         payment by, or distribution of assets of, the Company of any kind or
         character, whether in cash, property or securities, including any such
         payment or distribution which may be payable or deliverable by reason
         of the payment of any other indebtedness of the Company being
         subordinated to the payment of Contract Adjustment Payments on the
         Purchase Contracts

                                      -37-

         underlying the Securities, shall be received by the Agent or the
         Holders of any of the Securities when such payment or distribution is
         prohibited pursuant to Sections 5.2(b) through (n), such payment or
         distribution shall be paid over to the holders of such Senior
         Indebtedness or their representative or representatives or to the
         trustee or trustees under any indenture pursuant to which any
         instruments evidencing any such Senior Indebtedness may have been
         issued, ratably as aforesaid, for application to the payment of all
         Senior Indebtedness remaining unpaid until all such Senior Indebtedness
         shall have been paid in full, after giving effect to any concurrent
         payment or distribution (or provision therefor) to the holders of such
         Senior Indebtedness.

         (d) For purposes of Sections 5.2(b) through (n), the words "cash,
property or securities" shall not be deemed to include shares of stock of the
Company as reorganized or readjusted, or securities of the Company or any other
Person provided for by a plan of reorganization or readjustment, the payment of
which is subordinated at least to the extent provided in Sections 5.2(b) through
(n) with respect to such Contract Adjustment Payments on the Securities to the
payment of all Senior Indebtedness which may at the time be outstanding;
provided that (i) the indebtedness or guarantee of indebtedness, as the case may
be, that constitutes Senior Indebtedness is assumed by the Person, if any,
resulting from any such reorganization or readjustment, and (ii) the rights of
the holders of the Senior Indebtedness are not, without the consent of each such
holder adversely affected thereby, altered by such reorganization or
readjustment.

         (e) Any failure by the Company to make any payment on or perform any
other obligation under Senior Indebtedness, other than any indebtedness incurred
by the Company or assumed or guaranteed, directly or indirectly, by the Company
for money borrowed (or any deferral, renewal, extension or refunding thereof) or
any indebtedness or obligation as to which the provisions of Sections 5.2(b)
through (d) shall have been waived by the Company in the instrument or
instruments by which the Company incurred, assumed, guaranteed or otherwise
created such indebtedness or obligation, shall not be deemed a default or event
of default if (i) the Company shall be disputing its obligation to make such
payment or perform such obligation and (ii) either (A) no final judgment
relating to such dispute shall have been issued against the Company which is in
full force and effect and is not subject to further review, including a judgment
that has become final by reason of the expiration of the time within which a
party may seek further appeal or review, and (B) in the event a judgment that is
subject to further review or appeal has been issued, the Company shall in good
faith be prosecuting an appeal or other proceeding for review and a stay of
execution shall have been obtained pending such appeal or review.

         (f) Subject to the payment in full of all Senior Indebtedness, the
Holders of the Securities shall be subrogated (equally and ratably with the
holders of all obligations of the Company which by their express terms are
subordinated to Senior Indebtedness of the Company to the same extent as payment
of the Contract Adjustment Payments in respect of the Purchase Contracts
underlying the Securities is subordinated and which are entitled to like rights
of subrogation) to the rights of the holders of Senior Indebtedness to receive
payments or distributions of cash, property or securities of the Company
applicable to the Senior Indebtedness until all such Contract Adjustment
Payments owing on the Securities shall be paid in full, and as between the
Company, its creditors other than holders of such Senior Indebtedness and the
Holders, no such payment or distribution made to the holders of Senior
Indebtedness by virtue of Sections 5.2(b) through (n) that otherwise would have
been made to the Holders shall be deemed to be a payment by the Company on
account of such Senior Indebtedness, it being understood that the provisions of
Sections 5.2(b) through (n) are and are intended solely for the purpose of
defining the relative rights of the Holders, on the one hand, and the holders of
Senior Indebtedness, on the other hand.

                                      -38-

         (g) Nothing contained in Sections 5.2(b) through (n) or elsewhere in
this Agreement or in the Securities is intended to or shall impair, as among the
Company, its creditors other than the holders of Senior Indebtedness and the
Holders, the obligation of the Company, which is absolute and unconditional, to
pay to the Holders such Contract Adjustment Payments on the Securities as and
when the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of the Holders and creditors of
the Company other than the holders of Senior Indebtedness, nor shall anything
herein or therein prevent the Agent or any Holder from exercising all remedies
otherwise permitted by applicable law upon default under this Agreement, subject
to the rights, if any, under these Sections 5.2(b) through (n), of the holders
of Senior Indebtedness in respect of cash, property or securities of the Company
received upon the exercise of any such remedy.

         (h) Upon payment or distribution of assets of the Company referred to
in these Sections 5.2(b) through (n), the Agent and the Holders shall be
entitled to rely upon any order or decree made by any court of competent
jurisdiction in which any such dissolution, winding up, liquidation or
reorganization proceeding affecting the affairs of the Company is pending or
upon a certificate of the trustee in bankruptcy, receiver, assignee for the
benefit of creditors, liquidating trustee or agent or other person making any
payment or distribution, delivered to the Agent or to the Holders, for the
purpose of ascertaining the Persons entitled to participate in such payment or
distribution, the holders of the Senior Indebtedness and other indebtedness of
the Company, the amount thereof or payable thereon, the amount or amounts paid
or distributed thereon and all other facts pertinent thereto or to these
Sections 5.2(b) through (n).

         (i) The Agent shall be entitled to rely on the delivery to it of a
written notice by a Person representing himself to be a holder of Senior
Indebtedness (or a trustee or representative on behalf of such holder) to
establish that such notice has been given by a holder of Senior Indebtedness or
a trustee or representative on behalf of any such holder or holders. In the
event that the Agent determines in good faith that further evidence is required
with respect to the right of any Person as a holder of Senior Indebtedness to
participate in any payment or distribution pursuant to Sections 5.2(b) through
(n), the Agent may request such Person to furnish evidence to the reasonable
satisfaction of the Agent as to the amount of Senior Indebtedness held by such
Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under Sections 5.2(b) through (n), and, if such evidence is not
furnished, the Agent may defer payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

         (j) Nothing contained in Sections 5.2(b) through (n) shall affect the
obligations of the Company to make, or prevent the Company from making, payment
of the Contract Adjustment Payments, except as otherwise provided in these
Sections 5.2(b) through (n).

         (k) Each Holder of Securities, by his acceptance thereof, authorizes
and directs the Agent on his, her or its behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in Sections
5.2(b) through (n) and appoints the Agent his, her or its attorney-in-fact, as
the case may be, for any and all such purposes.

         (l) The Company shall give prompt written notice to the Agent of any
fact known to the Company that would prohibit the making of any payment of
moneys to or by the Agent in respect of the Securities pursuant to the
provisions of this Section 5.2. Notwithstanding the provisions of Sections
5.2(b) through (n) or any other provisions of this Agreement, the Agent shall
not be charged with knowledge of the existence of any facts that would prohibit
the making of any payment of moneys to or by the Agent, or the taking of any
other action by the Agent, unless and until the Agent shall have received
written notice thereof mailed or delivered to a Responsible Officer of the Agent
from the

                                      -39-

Company, any Holder, any paying agent or the holder or representative of any
Senior Indebtedness; provided that if at least two Business Days prior to the
date upon which by the terms hereof any such moneys may become payable for any
purpose, the Agent shall not have received with respect to such moneys the
notice provided for in this Section 5.2, then, anything herein contained to the
contrary notwithstanding, the Agent shall have full power and authority to
receive such moneys and to apply the same to the purpose for which they were
received and shall not be affected by any notice to the contrary that may be
received by it within two Business Days prior to or on or after such date.

         (m) The Agent in its individual capacity shall be entitled to all the
rights set forth in this Section 5.2 with respect to any Senior Indebtedness at
the time held by it, to the same extent as any other holder of Senior
Indebtedness and nothing in this Agreement shall deprive the Agent of any of its
rights as such holder.

         (n) No right of any present or future holder of any Senior Indebtedness
to enforce the subordination herein shall at any time or in any way be
prejudiced or impaired by any act or failure to act on the part of the Company
or by any noncompliance by the Company with the terms, provisions and covenants
of this Agreement, regardless of any knowledge thereof which any such holder may
have or be otherwise charged with.

         (o) Nothing in this Section 5.2 shall apply to claims of, or payments
to, the Agent under or pursuant to Section 7.7 hereof.

         With respect to the holders of Senior Indebtedness, (i) the duties and
obligations of the Agent shall be determined solely by the express provisions of
this Agreement; (ii) the Agent shall not be liable except for the performance of
such duties and obligations as are specifically set forth in this Agreement;
(iii) no implied covenants or obligations shall be read into this Agreement
against the Agent; and (iv) the Agent shall not be deemed to be a fiduciary as
to such holders.

         Section 5.3 Deferral of Payment Dates for Contract Adjustment Payments.

         (a) The Company shall have the right, at any time prior to the Purchase
Contract Settlement Date, to defer the payment of any or all of the Contract
Adjustment Payments otherwise payable on any Payment Date, but only if the
Company shall give the Holders and the Agent written notice of its election to
defer such payment (specifying the amount to be deferred) at least ten Business
Days prior to the earlier of (i) the next succeeding Payment Date or (ii) the
date the Company is required to give notice of the Record Date or Payment Date
with respect to payment of such Contract Adjustment Payments to the NYSE or
other applicable self-regulatory organization or to Holders of the Securities,
but in any event not less than one Business Day prior to such Record Date. Any
Contract Adjustment Payments so deferred shall, to the extent permitted by law,
bear additional Contract Adjustment Payments thereon at the rate of 9% per year
(computed on the basis of a 360-day year of twelve 30-day months), compounded
quarterly up to but not including each succeeding Payment Date, until paid in
full (such deferred installments of Contract Adjustment Payments, if any,
together with the additional Contract Adjustment Payments accrued thereon, being
referred to herein as the "Deferred Contract Adjustment Payments") . Deferred
Contract Adjustment Payments, if any, shall be due on the next succeeding
Payment Date except to the extent that payment is deferred pursuant to this
Section 5.3. No Contract Adjustment Payments may be deferred to a date that is
on or after the Purchase Contract Settlement Date and no such deferral period
may end other than on a Payment Date. If the Purchase Contracts are terminated
upon the occurrence of a Termination Event, the Holder's right to receive
Contract Adjustment Payments, if any, and Deferred Contract Adjustment Payments
will terminate.

                                      -40-

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

         (c) In the event that the Company elects to defer the payment of
Contract Adjustment Payments on the Purchase Contracts until the Purchase
Contract Settlement Date, each Holder will receive on the Purchase Contract
Settlement Date in lieu of a cash payment a number of shares of Common Stock (in
addition to a number of shares of Common Stock equal to the Settlement Rate)
equal to (x) the aggregate amount of Deferred Contract Adjustment Payments
payable to such Holder divided by (y) the Applicable Market Value.

         (d) No fractional shares of Common Stock will be issued by the Company
with respect to the payment of Deferred Contract Adjustment Payments on the
Purchase Contract Settlement Date. In lieu of fractional shares otherwise
issuable with respect to such payment of Deferred Contract Adjustment Payments,
the Holder will be entitled to receive an amount in cash equal to the fraction
of a share times the Applicable Market Value as provided in Section 5.11 hereof.

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

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

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

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

                  (iv) dividends or distributions in capital stock of the
         Company (or rights to acquire capital stock) or repurchases,
         acquisitions or redemptions of capital stock in exchange for or out of
         the net cash proceeds of the sale of the Company's capital stock (or
         securities convertible into or exchangeable for shares of the Company's
         capital stock);

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

                                      -41-

                  (vi) mandatory sinking fund payments with respect to any
         series of preferred stock of the Company; provided that the aggregate
         stated value of all such series outstanding at the time of such payment
         does not exceed 5% of the aggregate value of (1) the total principal
         amount of all then outstanding bonds or other securities representing
         secured indebtedness issued or assumed by the Company and (2) the
         Company's capital and surplus to be stated on the Company's books of
         account after giving effect to such payment; provided that any moneys
         deposited in to any sinking fund and not in violation of this clause
         (vi) may thereafter be applied to the purchase or redemption of such
         preferred stock in accordance with the terms of such sinking fund
         without regard to the foregoing restrictions.

         Section 5.4 Initial Remarketing and Secondary Remarketing.

         (a) 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 Notes (the "Initial
Remarketing") on the third Business Day immediately preceding May 16, 2005 (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 Notes to be remarketed that are part of Corporate Units.
Concurrently, the Collateral Agent, pursuant to the terms of the Pledge
Agreement, or the Custodial Agent, pursuant to clause (c) below, will present
for remarketing such Notes (and the Separate Notes that are to be remarketed
pursuant to clause (c) below) to the Remarketing Agent. Upon receipt of such
notice from the Agent and such Notes from the Collateral Agent or Custodial
Agent, the Remarketing Agent will, on the Initial Remarketing Date, use its
reasonable best efforts to remarket such Notes on such date at a price of 100.5%
of the sum of the Treasury Portfolio Purchase Price plus the Separate Notes
Purchase Price. If the Remarketing Agent is able to remarket the Notes at a
price equal to or greater than 100.5% of the Treasury Portfolio Purchase Price
plus the Separate Notes 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 not exceeding 25 basis points (0.25%) of the sum
of the Treasury Portfolio Purchase Price plus the Separate Notes Purchase Price
from any amount of such proceeds in excess of the Treasury Portfolio Purchase
Price plus the Separate Notes Purchase Price. With respect to Separate Notes,
any proceeds of the Initial Remarketing in excess of the Remarketing Fee or
attributable to the Separate Notes will be remitted to the Custodial Agent for
payment to the Holders of Separate Notes. With respect to Notes that are part of
Corporate Units, any proceeds in excess of those required to pay the Treasury
Portfolio Purchase Price and the Remarketing Fee with respect to such Notes will
be remitted to the Agent for payment to the Holders of the related Corporate
Units. A Corporate Unit Holder whose 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 Notes of Holders of Corporate
Units and will be pledged to the Collateral Agent to secure the Corporate Unit
Holders' obligation to pay the Purchase Price for the shares of Common Stock
under the related Purchase Contracts on the Purchase Contract Settlement Date.
Following the occurrence of a Successful Initial Remarketing, the Holders of
Corporate Units and the Collateral Agent shall have such security interests,
rights and obligations with respect to the Treasury Portfolio as the Holder of
Corporate Units and the Collateral Agent had in respect of the Notes, as the
case may be, subject to the Pledge thereof as provided in Sections 2, 3, 4, 5
and 6 of the Pledge Agreement, and any reference herein or in the Certificates
to the Notes shall be deemed to be a reference to such Treasury Portfolio and
any reference herein or in the Certificates to interest on the Notes shall be

                                      -42-

deemed to be a reference to corresponding distributions on the Treasury
Portfolio. The Company may cause to be made in any Corporate Unit Certificates
thereafter to be issued such change in phraseology and form (but not in
substance) as may be appropriate to reflect the substitution of the Treasury
Portfolio for Notes as collateral.

         If, (i) despite using its reasonable best efforts, the Remarketing
Agent cannot remarket the related Notes (other than to the Company) at a price
equal to or greater than 100.5% of the sum of the Treasury Portfolio Purchase
Price plus the Separate Notes Purchase Price, or (ii) the Initial Remarketing
has not occurred because of a condition precedent to the remarketing has not
been fulfilled, 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 May 16, 2005 in
an Authorized Newspaper. The Notes will continue to be a component of Corporate
Units, and another remarketing may be attempted as described in Section 5.4(b)

         (b) In the event of a Failed Initial Remarketing and unless a Tax Event
Redemption has occurred, the Company shall engage the Remarketing Agent pursuant
to the Remarketing Agreement to sell the Notes (the "Secondary Remarketing") on
the third Business Day immediately preceding July 1, 2005 (the "Secondary
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 Secondary Remarketing Date, the Remarketing Agent of the aggregate
principal amount of Notes to be remarketed that are part of Corporate Units.
Concurrently, the Collateral Agent, pursuant to the terms of the Pledge
Agreement, or the Custodial Agent, pursuant to clause (c) below, will present
for remarketing such Notes (and the Separate Notes that are to be remarketed
pursuant to clause (c) below) to the Remarketing Agent. Upon receipt of such
notice from the Agent and such Notes from the Collateral Agent or Custodial
Agent, the Remarketing Agent will, on the Secondary Remarketing Date, use its
reasonable best efforts to remarket such Notes on such date at a price of 100.5%
of the sum of the Treasury Portfolio Purchase Price plus the Separate Notes
Purchase Price. If the Remarketing Agent is able to remarket the Notes at a
price equal to or greater than 100.5% of the Treasury Portfolio Purchase Price
plus the Separate Notes Purchase Price (a "Successful Secondary Remarketing"),
the portion of the proceeds from such Successful Secondary Remarketing equal to
the Treasury Portfolio Purchase Price will be applied to purchase the Treasury
Portfolio. In addition, the Remarketing Agent may deduct as the Remarketing Fee
an amount not exceeding 25 basis points (0.25%) of the sum of the Treasury
Portfolio Purchase Price plus the Separate Notes Purchase Price from any amount
of such proceeds in excess of the Treasury Portfolio Purchase Price plus the
Separate Notes Price. With respect to Separate Notes, any proceeds of the
Secondary Remarketing in excess of the Remarketing or attributable to the
Separate Notes will be remitted to the Custodial Agent for payment to the
Holders of Separate Notes. With respect to Notes that are part of Corporate
Units, any proceeds in excess of those required to pay the Treasury Portfolio
Purchase Price and the Remarketing Fee with respect to such Notes will be
remitted to the Agent for payment to the Holders of the related Corporate Units.
A Corporate Unit Holder whose 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 Notes of Holders of Corporate
Units and will be pledged to the Collateral Agent to secure the Corporate Unit
Holders' obligation to pay the Purchase Price for the shares of Common Stock
under the related Purchase Contracts on the Purchase Contract Settlement Date.
Following the occurrence of a Successful Secondary Remarketing, the Holders of
Corporate Units and the Collateral Agent shall have such security interests,
rights and obligations with respect to the Treasury Portfolio as the Holder of
Corporate Units and the Collateral Agent had in respect of the Notes, as the
case may be, subject to the Pledge thereof as provided in Sections 2, 3, 4, 5
and 6 of the Pledge Agreement, and any reference herein or in the Certificates
to the Notes shall be deemed to be a reference to such Treasury Portfolio and
any reference herein or in the Certificates to interest on the Notes

                                      -43-

shall be deemed to be a reference to corresponding distributions on the Treasury
Portfolio. The Company may cause to be made in any Corporate Unit Certificates
thereafter to be issued such change in phraseology and form (but not in
substance) as may be appropriate to reflect the substitution of the Treasury
Portfolio for Notes as collateral.

         If, (i) despite using its reasonable best efforts, the Remarketing
Agent cannot remarket the related Notes (other than to the Company) at a price
equal to or greater than 100.5% of the sum of the Treasury Portfolio Purchase
Price plus the Separate Notes Purchase Price, or (ii) the Secondary Remarketing
has not occurred because of a condition precedent to the remarketing has not
been fulfilled, the remarketing will be deemed to have failed (a "Failed
Secondary Remarketing"). The Company will cause a notice of a Failed Secondary
Remarketing to be published on the second Business Day immediately preceding
July 1, 2005 in an Authorized Newspaper. The Notes will continue to be a
component of Corporate Units, and another remarketing may be attempted as
described in Section 5.5(b).

         (c) A Holder of a Note that is no longer part of a Corporate Unit may
elect to have such Note remarketed in the Initial Remarketing and, upon a Failed
Initial Remarketing, the Secondary Remarketing. A Holder making such an election
must notify the Custodial Agent and deliver such Notes to the Custodial Agent
prior to 11:00 a.m. (New York City time) on the second Business Day immediately
preceding the Initial Remarketing Date or the Secondary Remarketing Date, as
applicable, of the aggregate principal amount of Separate Notes that are to be
remarketed. Any such notice will be irrevocable and may not be conditioned upon
the level at which the Reset Rate is established in the Remarketing. By 11:00
a.m. (New York City time) on the Business Day immediately preceding the Initial
Remarketing Date or Secondary Remarketing Date, as applicable, the Custodial
Agent shall cause such Separate Notes to be presented to the Remarketing Agent
for the Initial Remarketing or the Secondary Remarketing, as the case may be.

         (d) Not later than seven calendar days nor more than 15 calendar days
prior to the Initial Remarketing Date and, upon a Failed Initial Remarketing,
the Secondary Remarketing Date, the Company shall notify the Agent and shall
request that the Clearing Agency notify the Beneficial Owners or Clearing Agency
participants holding securities of the procedures followed in the Initial
Remarketing or the Secondary Remarketing, as the case may be.

         (e) If required by applicable law, the Company agrees to endeavor to
ensure that a registration statement with regard to the full amount of the Notes
to be remarketed in the Initial Remarketing and, upon a Failed Initial
Remarketing, the Secondary Remarketing shall be effective with the Securities
and Exchange Commission in a form that will enable the Remarketing Agent to rely
on it in connection with the Initial Remarketing and the Secondary Remarketing.

         Section 5.5 Payment of Purchase Price, Cash Settlement, Final
                     Remarketing.

         (a)      (i) Unless a Tax Event Redemption, Successful Initial
         Remarketing, Successful Secondary Remarketing, Termination Event or
         Early Settlement has occurred, each Holder of a Corporate Unit may pay
         in cash ("Cash Settlement") the Purchase Price for the shares of Common
         Stock to be purchased pursuant to a Purchase Contract if such Holder
         notifies the Agent by use of a notice in substantially the form of
         Exhibit E hereto of its intention to make a Cash Settlement. Such
         notice shall be made 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.

                                      -44-

                  (ii) A Holder of a Corporate Unit 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 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.

                  (iii) If a Holder of a Corporate Unit fails to notify the
         Agent of its intention to make a Cash Settlement in accordance with
         clause (i) above, such Holder shall be deemed to have consented to the
         disposition of the pledged Notes pursuant to the Final Remarketing as
         described in Section 5.5(b) below. If a Holder of a Corporate Unit does
         notify the Agent as provided in clause (i) above of its intention to
         pay the Purchase Price in cash, but fails to make such payment as
         required by clause (ii) above, such failure shall constitute a default;
         however, the 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 Notes, including but not
         limited to those rights specified in Section 5.5(d) below.

         (b)      (i) Unless a Tax Event Redemption, a Successful Initial
         Remarketing or a Successful Secondary Remarketing has occurred, the
         Notes of Corporate Unit Holders who have not notified the Agent of
         their intention to effect a Cash Settlement as provided in clause (i)
         of Section 5.5(a) and the Separate Notes that are to be remarketed
         pursuant to clause (ii) below will be sold by the Remarketing Agent
         (the "Final Remarketing") on the third Business Day immediately
         preceding the Purchase Contract Settlement Date (the "Final Remarketing
         Date"). The Agent shall notify, by 10:00 a.m., New York City time, on
         the Business Day immediately preceding the Final Remarketing Date, the
         Remarketing Agent of the aggregate principal amount of Notes that are
         part of Corporate Units to be remarketed. Concurrently, the Collateral
         Agent, pursuant to the terms of the Pledge Agreement, or the Custodial
         Agent pursuant to clause (ii) below, will present for remarketing such
         Notes to the Remarketing Agent. Upon receipt of such notice from the
         Agent and such Notes (and the Separate Notes that are to be remarketed
         pursuant to clause (ii) below) from the Collateral Agent or Custodial
         Agent, the Remarketing Agent will, on the Final Remarketing Date, use
         its reasonable best efforts to remarket such Notes on such date at a
         price of 100.5% of the sum of the aggregate principal amount of such
         Notes plus the Separate Notes Purchase Price. If the Remarketing Agent
         is able to remarket the Notes at a price equal to or greater than 100%
         of the sum of the aggregate principal amount of Notes plus the Separate
         Notes Purchase Price (a "Successful Final Remarketing"), the
         Remarketing Agent will remit the entire amount of the proceeds from
         such Successful Final Remarketing to the Collateral Agent; provided
         that the Remarketing Agent may deduct as the Remarketing Fee an amount
         not exceeding 25 basis points (0.25%) of the sum of the aggregate
         principal amount of the remarketed Notes plus the Separate Notes
         Purchase Price from any amount of the proceeds of a Successful Final
         Remarketing in excess of the sum of the aggregate principal amount of

                                      -45-

         the remarketed Notes plus the Separate Notes Purchase Price. The
         portion of the entire proceeds which is equal to the aggregate
         principal amount of the remarketed Notes will automatically be applied
         by the Collateral Agent, in accordance with the Pledge Agreement, to
         satisfy in full such Corporate Unit Holders' obligations to pay the
         Purchase Price for the shares of Common Stock under the related
         Purchase Contracts on the Purchase Contract Settlement Date. With
         respect to the Separate Notes, any proceeds of the Final Remarketing in
         excess of the Remarketing Fee or attributable to the Separate Notes
         will be remitted to the Custodial Agent for payment to the Holders of
         Separate Notes. With respect to Notes that are part of Corporate Units,
         any proceeds in excess of those required to pay the Purchase Price for
         the Purchase Contracts related to such Corporate Units and the
         Remarketing Fee will be remitted to the Agent for payment to the
         Holders of such Corporate Units. A Corporate Unit Holder whose Notes
         are so remarketed will not otherwise be responsible with respect to
         such Notes for the payment of any Remarketing Fee in connection
         therewith. If, (i) despite using its reasonable best efforts, the
         Remarketing Agent cannot remarket the Notes (other than to the Company)
         at a price not less than 100% of the sum of the aggregate principal
         amount of the Notes plus the Separate Notes Purchase Price, or (ii) the
         remarketing has not occurred because of a condition precedent to the
         remarketing has not been fulfilled, the remarketing will be deemed to
         have failed (a "Failed Final Remarketing") and the holder of the Notes
         will have a right to put the Notes to the Company as described in
         clause (c) below or, 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 Notes,
         including those actions specified in clause (d) below. The Company will
         cause a notice of such Failed Final Remarketing to be published on the
         second Business Day immediately preceding the Purchase Contract
         Settlement Date in an Authorized Newspaper.

                  (ii) A Holder of a Note that is no longer part of a Corporate
         Unit may elect to have such Note remarketed in the Final Remarketing. A
         Holder making such an election must notify the Custodial Agent and
         deliver such Notes to the Custodial Agent prior to 11:00 a.m. (New York
         City time) on the second Business Day immediately preceding the Final
         Remarketing Date of the aggregate principal amount of Notes that are
         not part of Corporate Units to be remarketed. Any such notice will be
         irrevocable and may not be conditioned upon the level at which the
         Reset Rate is established in the Remarketing. By 11:00 a.m. (New York
         City time) on the Business Day immediately preceding the Final
         Remarketing Date, the Custodial Agent shall cause such Notes to be
         presented to the Remarketing Agent for Final Remarketing.

                  (iii) Not later than seven calendar days nor more than 15
         calendar days prior to the Final Remarketing Date, the Company shall
         notify the Agent, and shall request that the Clearing Agency notify the
         Beneficial Owners or Clearing Agency participants holding securities of
         the procedures to be followed in the Final Remarketing.

                  (iv) If required by applicable law, the Company agrees to
         endeavor to ensure that a registration statement with regard to the
         full amount of the Notes to be remarketed in the Final Remarketing
         shall be effective with the Securities and Exchange Commission in a
         form that will enable the Remarketing Agent to rely on it in connection
         with the Remarketing.

                                      -46-

         (c) If a Failed Final Remarketing has occurred, each holder of the
Notes shall have the right ("Put Option") to put such Notes to the Company on
August 16, 2005, or if such date is not a Business Day, on the next succeeding
Business Day (the "Put Option Settlement Date") at a repayment price equal to
the principal amount of the Notes plus an amount equal to any accrued and unpaid
interest thereon to the date of payment. To exercise the Put Option, the
Indenture Trustee must receive from the holder of the Notes, on or prior to 5:00
p.m., New York City time, on the second Business Day immediately preceding the
Put Option Settlement Date, at its Corporate Trust Office, or at an office or
agency maintained by the Company in the Borough of Manhattan, The City of New
York as contemplated by Section 1002 of the Indenture, the Notes to be
repurchased with the form on the reverse of or otherwise accompanying such Notes
duly completed. Any such notice received by the Indenture Trustee shall be
irrevocable. All questions as to the validity, eligibility (including time of
receipt) and acceptance of the Notes for repayment shall be determined by the
Company, whose determination shall be final and binding. Holders of Notes will
be notified not later than seven nor more than 15 calendar days prior to the
third Business Day immediately preceding August 16, 2005 of the procedures that
must be followed if such holders wish to exercise their Put Option. The payment
of the repayment price in respect of the Notes shall be made no later than 12:00
noon, New York City time, on the Put Option Settlement Date. If a Holder has
exercised the Put Option but has not otherwise settled the Purchase Contracts in
cash by the close of business on the Business Day immediately prior to the
Purchase Contract Settlement Date, the put price will be applied by the
Collateral Agent, in accordance with the terms of the Pledge Agreement, to
satisfy in full the obligations of the Holder to pay the Purchase Price for the
shares of Common Stock under the related Purchase Contracts on the Purchase
Contract Settlement Date.

         (d) With respect to any Notes beneficially owned by Holders who have
elected Cash Settlement but failed to deliver cash as required in clause (a)(ii)
above, or with respect to Notes which are subject to a Failed Final Remarketing,
and for which the Put Option was not exercised, 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 clause (i) below, may, among
other things, permit the Company to (i) retain and cancel the Notes or (ii)
cause the Notes to be sold in one or more public or private sales, in either
case, in full satisfaction of the Holders' obligations under the Purchase
Contracts.

         (e) Unless a Termination Event or an Early Settlement has occurred, the
Purchase Contract underlying each Treasury Unit and, if a Tax Event Redemption,
a Successful Initial Remarketing or a Successful Secondary Remarketing has
occurred, each Corporate Unit will be settled with the Proceeds at maturity of
the Treasury Security or the Applicable Ownership Interest (as defined in clause
(i) of the definition of such term) in the Treasury Portfolio, as applicable.
Upon receipt of such Proceeds, the Collateral Agent will invest the Proceeds
promptly in Permitted Investments and pay the Proceeds to the Company on the
Purchase Contract Settlement Date in accordance with the terms of this Agreement
and the Pledge Agreement. Any such Proceeds received by the Collateral Agent in
excess of the Purchase Price and 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
Holders.

         (f) Any distribution to Holders of excess funds and interest described
above, shall be payable at the New York Office 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, or, at the
option of the Company, by wire transfer to the bank account designated by such
Holders in writing, such payments to be made to the same Persons entitled to
receive Common Stock with respect to the Purchase Contracts referred to in
clause (d) above.

                                      -47-

         (g) Unless a Holder settles the underlying Purchase Contract through
Early Settlement in the manner described in Section 5.10 hereof, the Company
shall not be obligated to issue any shares of 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 shares of
Common Stock to be purchased thereunder in the manner set forth in this Section
5.5.

         (h) Upon Cash Settlement of any Purchase Contract, (i) the Collateral
Agent will in accordance with the terms of the Pledge Agreement cause the
pledged Notes 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
Notes (or, if no such instructions are given to the Agent by the Holder, the
Agent shall hold such Notes and any distributions thereon in the name of the
Agent or its nominee in trust for the benefit of such Holder pending receipt of
such instructions).

         (i) 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 and the Purchase Price.

         Section 5.6 Issuance of Shares of Common Stock.

         Unless a Termination Event or an Early Settlement shall have occurred,
on the Purchase Contract Settlement Date, upon the Company's receipt of payment
in full of the Purchase Price for the shares of Common Stock purchased by the
Holders pursuant to the foregoing provisions of this Article and subject to
Sections 5.7(b) and 5.11 hereof, the Company shall issue and deposit with the
Agent, for the benefit of the Holders of the Outstanding Securities, one or more
certificates representing newly issued shares of Common Stock registered in the
name of the Agent (or its nominee) as custodian for the Holders (such
certificates for shares of Common Stock, together with any dividends or
distributions for which both a record date and payment date for such dividend or
distribution has occurred on or 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 V (after taking into account all Securities then held by such
Holder) together with cash in lieu of fractional shares as provided in Section
5.11 hereof and any dividends or distributions with respect to such shares
constituting part of the Purchase Contract Settlement Fund, but without any
interest thereon, and the Certificate so surrendered shall forthwith be
cancelled. Such shares shall be registered in the name of the Holder or the
Holder's designee as specified in the settlement instructions provided by the
Holder to the Agent. If any shares of Common Stock issued in respect of a
Purchase Contract are to be registered to a Person other than the Person in
whose name the Certificate evidencing such Purchase Contract is registered, no
such registration shall be made unless the Person requesting such registration
has paid any transfer and other taxes required by reason of such registration in
a name other than that of the registered Holder of 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.

                                      -48-

         Section 5.7 Adjustment of Settlement Rate.

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

         (1) In case the Company shall pay or make a stock dividend or other
distribution on the Common Stock in shares of Common Stock, the Settlement Rate,
as in effect at the opening of business on the day following the date fixed for
the determination of stockholders entitled to receive such dividend or other
distribution shall be increased by dividing such Settlement Rate by a fraction
of which (i) the numerator shall be the number of shares of Common Stock
outstanding at the close of business on the date fixed for such determination
and (ii) the denominator shall be the sum of such number of shares and the total
number of shares constituting such dividend or other distribution, such increase
to become effective immediately after the opening of business on the day
following the date fixed for such determination. For the purposes of this clause
(1), the number of shares of Common Stock at any time outstanding shall not
include shares held in the treasury of the Company but shall include any shares
issuable in respect of any share certificates issued in lieu of fractions of
shares of Common Stock. The Company shall not pay any stock dividend or make any
distribution on shares of Common Stock held in the treasury of the Company.

         (2) In case the Company shall issue rights, options or warrants, other
than pursuant to any dividend reinvestment plan or share purchase plan, 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 stockholders entitled to receive such
rights, options or warrants, to subscribe for or purchase shares of Common Stock
at a price per share less than the Current Market Price per share of the Common
Stock on the date fixed for the determination of stockholders entitled to
receive such rights, options or warrants (other than pursuant to a dividend
reinvestment plan or share purchase 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 of which (i)
the numerator shall be the number of shares of Common Stock outstanding at the
close of business on the date fixed for such determination plus the number of
shares of Common Stock which the aggregate offering price of the total number of
shares of Common Stock so offered for subscription or purchase would purchase at
such Current Market Price and (ii) the denominator shall be the number of shares
of Common Stock outstanding at the close of business on the date fixed for such
determination plus the number of shares of Common Stock so offered for
subscription or purchase, such increase to become effective immediately after
the opening of business on the day following the date fixed for such
determination. For purposes of this clause (2), the number of shares of Common
Stock at any time outstanding shall not include shares held in the treasury of
the Company but shall include any shares issuable in respect of any share
certificates issued in lieu of fractions of shares of Common Stock. The Company
shall not issue any such rights, options or warrants in respect of shares of
Common Stock held in the treasury of the Company.

         (3) In case outstanding shares of Common Stock shall be subdivided or
split into a greater number of shares of Common Stock, the Settlement Rate in
effect at the opening of business on the day following the day upon which such
subdivision or split becomes effective shall be proportionately increased, and,
conversely, in case outstanding shares of Common Stock shall each be combined
into a smaller number of shares of Common Stock, the Settlement Rate in effect
at the opening of business on the day following the day upon which such
combination becomes effective shall be proportionately reduced, such increase or
reduction, as the case may

                                      -49-

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, shares of capital
stock, securities, cash or other property (but excluding any rights or warrants
referred to in clause (2) of this Section 5.7(a), any dividend or distribution
paid exclusively in cash, and any dividend or distribution referred to in clause
(1) of this Section 5.7(a)), 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 the
determination of stockholders entitled to receive such distribution by a
fraction of which (i) the numerator shall be the Current Market Price per share
of the 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) on such
date of the portion of the evidences of indebtedness, shares of capital stock,
securities, cash or other property so distributed applicable to one share of
Common Stock and (ii) the denominator shall be such Current Market Price per
share of Common Stock, such adjustment to become effective immediately prior to
the opening of business on the day following the date fixed for the
determination of stockholders entitled to receive such distribution. In any case
in which this clause (4) is applicable, clauses (1) and (2) of this Section
5.7(a) 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 (i) regular quarterly cash
distributions, (ii) any cash that is distributed in a Reorganization Event to
which Section 5.7(b) applies or (iii) cash that is distributed as part of a
distribution referred to in clause (4) of this Section 5.7(a)) 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
(excluding regular quarterly cash distributions) within the 12 months preceding
the date of payment of such distribution and in respect of which no adjustment
pursuant to this clause (5) or clause (6) of this Section 5.7(a) has been made
and (III) the aggregate of any cash plus the fair market value, as of the
expiration of the applicable tender or exchange offer referred to below (as
determined by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution), of consideration payable in respect of any
tender or exchange offer (other than consideration payable in respect of any
odd-lot tender offer) by the Company or any of its Subsidiaries for all or any
portion of the Common Stock concluded within the 12 months preceding the date of
payment of the distribution described in clause (I) above and in respect of
which no adjustment pursuant to this clause (5) or clause (6) of this Section
5.7(a) has been made, exceeds 5% of the product of the Current Market Price per
share of the Common Stock on the date for the determination of holders of shares
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 the Common Stock on the
date fixed for such determination less an amount equal to the quotient of (x)
the combined amount distributed or payable in the transactions described in
clauses (I), (II) and (III) above and (y) the number of shares of Common Stock
outstanding on such date for determination and (ii) the denominator of which
shall be equal

                                      -50-

to the Current Market Price per share of the Common Stock on the date fixed for
such determination.

         (6) In case (I) a tender or exchange offer made by the Company or any
Subsidiary of the Company for all or any portion of the Common Stock shall
expire and such tender or exchange offer (as amended upon the expiration
thereof) shall require the payment to stockholders (based on the acceptance (up
to any maximum specified in the terms of the tender or exchange offer) of
Purchased Shares) of an aggregate consideration having a fair market value (as
determined by the Board of Directors, whose determination shall be conclusive
and described in a Board Resolution) that combined together with (II) the
aggregate of the cash plus the fair market value (as determined by the Board of
Directors, whose determination shall be conclusive and described in a Board
Resolution), as of the expiration of such tender or exchange offer, of
consideration payable in respect of any other tender or exchange offer (other
than consideration payable in respect of any odd-lot tender 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 clause (5) of
this Section 5.7(a) or this clause (6) has been made and (III) the aggregate
amount of any distributions (other than regular quarterly cash distributions) to
all holders of the Company's Common Stock made exclusively in cash within the 12
months preceding the expiration of such tender or exchange offer and in respect
of which no adjustment pursuant to clause (5) of this Section 5.7(a) or this
clause (6) has been made, exceeds 5% of the product of the Current Market Price
per share of the Common Stock as of the last time (the "Expiration Time")
tenders could have been made pursuant to such tender or exchange offer (as it
may be amended) times the number of shares of Common Stock outstanding
(including any tendered shares) 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 as 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 the Common Stock as of the Expiration Time and (ii) the
number of shares of Common Stock outstanding (including any tendered shares) as
of the Expiration Time less (B) the amount of cash plus the fair market value
(determined as aforesaid) of the aggregate consideration payable to stockholders
based on the transactions described in clauses (I), (II) and (III) above
(assuming in the case of clause (I) the acceptance, up to any maximum specified
in the terms of the tender or exchange offer, of Purchased Shares), and (ii) the
denominator of which shall be equal to the product of (A) the Current Market
Price per share of the Common Stock as of the Expiration Time and (B) the number
of shares of Common Stock outstanding (including any tendered shares) as of the
Expiration Time less the number of all shares validly tendered and not withdrawn
as of the Expiration Time (the shares deemed so accepted, up to any such
maximum, being referred to as the "Purchased Shares").

         (7) The reclassification of Common Stock into securities including
securities other than Common Stock (other than any reclassification upon a
Reorganization Event to which Section 5.7(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 clause (4) of this Section 5.7(a)), 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

                                      -51-

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 clause (3) of this
Section 5.7(a)).

         (8) The "Current Market Price" per share of Common Stock on any day
means the average of the daily Closing Prices for the five consecutive Trading
Days selected by the Company commencing not more than 30 Trading Days before,
and ending not later than, the earlier of 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 clause (8), the term "ex date", when used with
respect to any issuance or distribution, shall mean the first date on which the
Common Stock trades regular way on the applicable exchange or in the applicable
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 that any
adjustments which by reason of this clause 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 clause (1), (2), (3), (4),
(5), (6), (7) or (10) of this Section 5.7(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 of which the numerator shall be the
Settlement Rate immediately after such adjustment pursuant to clause (1), (2),
(3), (4), (5), (6), (7) or (10) of this Section 5.7(a) and the denominator shall
be the Settlement Rate immediately before such adjustment; provided that if such
adjustment to the Settlement Rate is required to be made pursuant to the
occurrence of any of the events contemplated by clause (1), (2), (3), (4), (5),
(7) or (10) of this Section 5.7(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 5.7(a), it considers to be advisable
in order to avoid or diminish any income tax to any holders of shares of Common
Stock resulting from any dividend or distribution of capital stock or issuance
of rights or warrants to purchase or subscribe for capital 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.

         (1)      In the event of:

                  (i) any consolidation or merger of the Company with or into
         another Person (other than a merger or consolidation in which the
         Company is the continuing corporation and in which the 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,

                                      -52-

                  (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 described in clauses (i) to (iv) above, 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 (or upon any Early Settlement pursuant to clause (2) of
         Section 5.7(b)), 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. The adjustment described in the preceding sentence shall apply
         only to a Holder of Common Stock who 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 its
         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 5.7(b) 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 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 or leases 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 5.7. 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 5.7(b). The above provisions of
this Section 5.7(b) shall similarly apply to successive Reorganization Events.

         (2) In the event of a consolidation or merger in which (i) the Company
merges with or into another Person, (ii) there is any reclassification,
conversion, exchange or cancellation of outstanding shares of Common Stock, and
(iii) 30% or more of the total consideration paid to the Company's shareholders
for the outstanding shares of Common Stock consists of cash or cash equivalents
(a "Cash Merger"), then a Holder of a Security may settle his Purchase Contract
for cash in the manner described in Section 5.10 hereof, mutatis mutandis, at
the applicable Settlement Rate in effect immediately prior to the Cash Merger.

                                      -53-

         Within five Business Days after the date of the consummation of a Cash
Merger (the "Cash Merger Date"), the Company shall provide written notice to
Holders of Securities of such consummation (the "Cash Merger Notice"), which
shall specify the deadline for submitting a notice of Early Settlement pursuant
to this clause (2), the applicable Early Settlement Date, the applicable
Settlement Rate in effect immediately prior to the Cash Merger and the amount
(per share of Common Stock) of cash, securities and other consideration
receivable by the Holder upon settlement of each Purchase Contract as adjusted
pursuant to Section 5.7(b)(1).

         In this clause (2), the tenth Business Day after the date the Cash
Merger Notice is provided to the Holders by the Company shall be the applicable
Early Settlement Date and the deadline for submitting the notice to settle early
and the related cash payment of the Purchase Price shall be 5:00 p.m. (New York
City time) on the ninth Business Day after the date the Cash Merger Notice is
provided to the Holders by the Company.

         Treasury Unit Holders may only effect Early Settlement pursuant to this
clause (2) in integral multiples of 20 Purchase Contracts. Other than the
provisions relating to timing of notice and settlement, which shall be as set
forth above, the provisions of Section 5.1 shall apply with respect to an Early
Settlement following a Cash Merger pursuant to this clause (2).

         Notwithstanding the foregoing, no Early Settlement will be permitted
pursuant to this clause (2) unless, at the time such Early Settlement is
effected, there is an effective registration statement with respect to the
securities to be delivered in connection with such Early Settlement, if such a
registration statement is required (in the view of counsel, which need not be in
the form of a written opinion, for either the Company or the Agent) under the
Securities Act. If such a registration statement is so required, the Company
covenants and agrees to use its reasonable best efforts to (A) have in effect a
registration statement covering the securities to be delivered in respect of the
Purchase Contracts being settled and (B) provide a prospectus in connection
therewith, in each case in a form that the Agent may deliver to the applicable
Holders in connection with such Early Settlement.

         (c) All calculations and determinations pursuant to this Section 5.7
shall be made by the Company or its agent and the Agent shall have no
responsibility with respect thereto.

         Section 5.8 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 5.7 hereof 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 5.7 hereof (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.

                                      -54-

         (b) The Agent shall not at any time be under any duty or responsibility
to the Company 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
shares of Common Stock, or of any securities or property, which may at the time
be issued or delivered with respect to any Purchase Contract; and the Agent
makes no representation with respect thereto. The Agent shall not be responsible
for any failure of the Company to issue, transfer or deliver any shares of
Common Stock pursuant to a Purchase Contract or to comply with any of the
duties, responsibilities or covenants of the Company contained in this Article.

         Section 5.9 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 Notes or the appropriate
Applicable Ownership Interest in the Treasury Portfolio, as the case may be,
forming a part of such Securities in the case of Corporate Units, or Treasury
Securities in the case of Treasury Units, in accordance with the provisions of
Section 4.3 of the Pledge Agreement; provided that, to the extent that a Holder
of Corporate Units or Treasury Units would otherwise be entitled to receive less
than $1,000 principal amount at maturity of the 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 written instructions. 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.

                                      -55-

         Section 5.10 Early Settlement.

         (a) Subject to and upon compliance with the provisions of this Section
5.10, at the option of the Holder thereof, Purchase Contracts underlying
Securities having an aggregate Stated Amount of $1,000 or integral multiples
thereof may effect early settlement ("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. Holders of Treasury Units may only effect
Early Settlement of the related Purchase Contracts in integral multiples of 20
Treasury Units, and if a Tax Event Redemption, a Successful Initial Remarketing
or a Successful Secondary Remarketing has occurred and the Treasury Portfolio
has become a component of the Corporate Units, Purchase Contracts underlying the
Securities may only be settled in integral multiples of 32,000 Corporate Units.
In order to exercise the right to effect Early Settlement with respect to any
Purchase Contracts, the Holder of the Certificate evidencing Securities shall
deliver to the Agent at the Corporate Trust Office or at the New York Office an
"Election to Settle Early" form (on the reverse side of the Certificate) and any
other documents requested by the Agent and accompanied by payment (payable to
the Company in immediately available funds) in an amount (the "Early Settlement
Amount") equal to the product of (i) (A) the Stated Amount times (B) the number
of Purchase Contracts with respect to which the Holder has elected to effect
Early Settlement, plus (ii) if such delivery is made with respect to any
Purchase Contracts during the period from the close of business on any Record
Date next preceding any Payment Date to the opening of business on such Payment
Date, an amount equal to the Contract Adjustment Payments payable on such
Payment Date with respect to such Purchase Contracts.

         Except as provided in the immediately preceding sentence and subject to
Section 5.1 hereof, no payment shall be made upon Early Settlement of any
Purchase Contract on account of any Contract Adjustment Payments accrued on such
Purchase Contract or on account of dividends payable on the Common Stock issued
upon such Early Settlement, the record date for which payment occurs prior to
the Early Settlement Date. If the foregoing requirements are first satisfied
with respect to Purchase Contracts underlying any Securities prior to or at 5:00
p.m. (New York City time) on a Business Day, such day shall be the "Early
Settlement Date" with respect to such Securities and if such requirements are
first satisfied after 5:00 p.m. (New York City time) on a Business Day or on a
day that is not a Business Day, the "Early Settlement Date" with respect to such
Securities shall be the next succeeding Business Day (so long as such next
succeeding Business Day is not later than the fifth Business Day immediately
preceding the Purchase Contract Settlement Date)

         (b) No Early Settlement will be permitted under this Section 5.10
unless, at the time of delivery of the Election to Settle Early form or the time
the Early Settlement is effected, there is an effective registration statement
with respect to the shares of Common Stock to be issued and delivered in
connection with such Early Settlement, if such a registration statement is
required (in the view of counsel, which need not be in the form of a written
opinion, for either the Company or the Agent) under the Securities Act. If such
a registration statement is so required, the Company covenants and agrees to use
its reasonable best efforts to (A) have in effect a registration statement
covering the shares of Common Stock to be delivered in respect of the Purchase
Contracts being settled and (B) provide a prospectus in connection therewith, in
each case in a form that the Agent may use in connection with such Early
Settlement.

         (c) Upon Early Settlement of Purchase Contracts by a Holder of the
related Securities, except in the case of Early Settlement following a Cash
Merger as described in Section 5.7(b)(2), the Company shall issue, and the
Holder shall be entitled to receive 1.7218 shares of Common Stock on account of
each Purchase Contract as to which Early Settlement is effected (the "Early

                                      -56-

Settlement Rate"). The Early Settlement Rate shall be adjusted in the same
manner and at the same time as the Settlement Rate is adjusted.

         (d) Not later than the third Business Day after the applicable Early
Settlement Date, the Company shall cause:

                  (i) the shares of Common Stock issuable upon Early Settlement
         of Purchase Contracts to be issued and delivered, together with payment
         in lieu of any fraction of a share, as provided in Section 5.11 hereof;
         and

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

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

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

                  (ii) deliver to the Holder a certificate or certificates for
         the full number of shares of Common Stock issuable upon such Early
         Settlement, together with payment in lieu of any fraction of a share,
         as provided in Section 5.11 hereof; and

                  (iii) if so required under the Securities Act, deliver a
         prospectus for the shares of Common Stock issuable upon such Early
         Settlement as contemplated by Section 5.10(b).

         (f) In the event that Early Settlement is effected with respect to
Purchase Contracts underlying less than all the Securities evidenced by a
Certificate, upon such Early Settlement the Company shall execute and the Agent
shall authenticate, execute on behalf of the Holder 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.

                                      -57-

         Section 5.11 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 5.11 in a timely manner.

         Section 5.12 Charges and Taxes.

         The Company will pay all stock transfer and similar taxes attributable
to the initial issuance and delivery of the shares of Common Stock pursuant to
the Purchase Contracts and in payment of any Deferred Contract Adjustment
Payments; provided that the Company shall not be required to pay any such tax or
taxes which may be payable in respect of any exchange of or substitution for a
Certificate evidencing 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 or that no such tax is due.

                                   ARTICLE VI

                                    REMEDIES

         Section 6.1 Unconditional Right of Holders to Purchase Common Stock.

         The Holder of any Corporate Units or Treasury Units shall have the
right, which is absolute and unconditional, (A) subject to the right of the
Company to defer payment thereof pursuant to Section 5.3 hereof, and to the
forfeiture of any Deferred Contract Adjustment Payments upon Early Settlement
pursuant to Section 5.10(a) hereof or upon the occurrence of a Termination
Event, to receive payment of each installment of the Contract Adjustment
Payments, if any, with respect to the Purchase Contract constituting a part of
such Security on the respective Payment Date for such Security, and (B) to
purchase Common Stock pursuant to such Purchase Contract and, in each such case,
to institute suit for the enforcement of any such payment and right to purchase
Common Stock, and such rights shall not be impaired without the consent of such
Holder.

                                      -58-

         Section 6.2 Restoration of Rights and Remedies.

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

         Section 6.3 Rights and Remedies Cumulative.

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

         Section 6.4 Delay or Omission Not Waiver.

         No delay or omission of any Holder to exercise any right or remedy upon
a default shall impair any such right or remedy or constitute a waiver of any
such right. Every right and remedy given by this Article or by law to the
Holders may be exercised from time to time, and as often as may be deemed
expedient, by such Holders.

         Section 6.5 Undertaking for Costs.

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

                                      -59-

         Section 6.6 Waiver of Stay or Extension Laws.

         The Company covenants (to the extent that it may lawfully do so) that
it will not at any time insist upon, or plead, or in any manner whatsoever claim
or take the benefit or advantage of, any stay or extension law wherever enacted,
now or at any time hereafter in force, which may affect the covenants or the
performance of this Agreement; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such law
and covenants that it will not 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.

         months, or

                  (2) the Agent shall cease to be eligible under Section 7.8

         rehabilitation, conservation or liquidation,

                  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 the appointment of a successor Agent.

         (e) If the Agent shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Agent for any cause, the
Company, by a Board Resolution, shall promptly appoint a successor Agent and
shall comply with the applicable requirements of Section 7.10 hereof. If no
successor Agent shall have been so appointed by the Company and accepted
appointment in the manner required by Section 7.10 hereof, any Holder who has

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

         (a) In case of the appointment hereunder of a successor Agent, every
such successor Agent so appointed shall execute, acknowledge and deliver to the
Company and to the retiring Agent an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Agent shall become
effective and such successor Agent, without any further act, deed or conveyance,
shall become vested with all the rights, powers, agencies and duties of the
retiring Agent; but, on the request of

                                      -64-

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.

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

of such acceptance such successor Agent shall be qualified and eligible under
this Article.

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

which it may be consolidated, or any corporation resulting from any merger,
conversion or consolidation to which the Agent shall be a party, or any
corporation succeeding to all or substantially all the corporate trust business
of the Agent, shall be the successor of the Agent hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Certificates shall have been
authenticated and executed on behalf of the Holders, but not delivered, by the
Agent then in office, any successor by merger, conversion or consolidation to
such Agent 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
capacity as Registrar.

in 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 communication which is specified in such request, with reasonable
promptness after a tender to the Agent of the materials to be mailed and of
payment, or provision 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
each Holder of a Certificate, by his acceptance thereof, shall be deemed to have
agreed, that the Agent's execution of the Certificates on behalf of the Holders
shall be solely as agent and attorney-in-

                                      -65-

(including "backup" withholding) requirements imposed by applicable tax laws,
regulations or administrative practice with respect to (i) any payments made
with respect to the Securities or (ii) the issuance, delivery, holding,
transfer, redemption or exercise of rights under the Securities or the Notes.
Such compliance shall include, without limitation, (i) preparing, timely filing
with the applicable taxing authority, and (to the extent required under

reasonable efforts to obtain from Holders all IRS Forms (and similar forms under
applicable state, local, and foreign tax law) and other documentation required
under applicable tax laws in order to establish exemptions from or reductions in
withholding taxes.

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

         (c) The Agent shall maintain all appropriate records documenting
compliance with such requirements, until such time as all applicable periods of
limitation for assessing or collecting any taxes or penalties for failure to
comply fully with such requirements have expired, and shall make such records
available, on written request, to the Company or its authorized representative
within a reasonable period of time after receipt of such request.

authenticated, executed on behalf of the Holders and delivered by the Agent in
exchange for Outstanding Certificates.

         Section 9.1 Covenant Not to Merge, Consolidate, Sell or Convey Property
Except Under Certain Conditions.

         The Company covenants that it will not merge or consolidate with any
other Person (in a merger in which the Company in a Constituent 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 transaction or a
series of related transactions, unless (i) either the Company shall be the
continuing corporation, or the

                                      -68-

successor (if other than the Company) shall be a corporation organized and
existing under the laws of the United States of America or a state thereof or
the District of Columbia and such corporation shall expressly assume all the
obligations of the Company under the Purchase Contracts, this Agreement, the
Notes, the Indenture (including any supplemental indenture) to the extent the
Indenture relates to the Notes, the Remarketing Agreement and the Pledge
Agreement by one or more supplemental agreements in form reasonably satisfactory
to the Agent and the Collateral Agent, executed and delivered to the Agent and
the Collateral Agent by such corporation and (ii) the Company or such successor
corporation, as the case may be, shall not, immediately after such merger or
consolidation, or such sale, assignment, transfer, lease or conveyance, be in
default of its payment obligations under this Agreement or the Notes, or in
default of its obligations to deliver shares of Common Stock (or other property)
on the Purchase Contract Settlement Date or any Early Settlement Date, or in
material default in the performance of any other covenant hereunder or under the
Notes, the Indenture (including any supplemental indenture), to the extent the
Indenture relates to the Notes, the Remarketing Agreement, the Purchase
Contracts or the Pledge Agreement.

         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 hereof, 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, and its predecessor shall, except in the case of a lease,
be released from its obligations under this Agreement. Such successor
corporation thereupon may cause to be signed, and may issue either in its own
name or in the name of The St. Paul Companies, 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 hereof and 7.3 hereof, 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 hereunder to the consummation of any such consolidation, merger, sale,
assignment, transfer, lease or conveyance have been met.

comply with all applicable securities laws regulating the offer, issuance and
delivery of shares of Common Stock upon settlement of Purchase Contracts and
will endeavor to list such shares on each national securities exchange or
automated quotation system on which the Common Stock is then listed. The Company
will not pay any dividend or make any distribution on shares of Common Stock
held in the treasury of the Company.

         Section 10.5 Tax Treatment.

         The Company covenants and agrees to treat each Holder as the owner, for
United States federal income tax purposes, of the applicable interest in the
Collateral Account, including Notes and Applicable Ownership Interest in the
Treasury Portfolio or the Treasury Securities.

                                      -71-

                 (Form of Reverse of Corporate Unit Certificate)

         Each Purchase Contract evidenced hereby is governed by a Purchase
Contract Agreement, dated as of July 31, 2002 (as may be supplemented from time
to time, the "Purchase Contract Agreement"), between the Company and JPMorgan
Chase Bank, as Purchase Contract Agent (including its successors thereunder,
herein called the "Agent"), to which Purchase Contract Agreement and
supplemental agreements thereto reference is hereby made for a description of
the respective rights, limitations of rights, obligations, duties and immunities
thereunder of the Agent, the Company and the Holders and of the terms upon which
the Corporate Unit 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
Corporate Unit 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
$29.04 (the "Threshold Appreciation Price"), 1.7218 shares of Common Stock per
Purchase Contract, (b) if the Applicable Market Value is less than the Threshold
Appreciation Price but is greater than $24.20, (the "Reference Price"), the
number of shares of Common Stock per Purchase Contract equal to the Stated
Amount divided by the Applicable Market Value and (c) if the Applicable Market
Value is less than or equal to the Reference Price, 2.0661 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 (other than an Early Settlement following a Cash Merger
pursuant to Section 5.7(b)(2) of the Purchase Contract Agreement) or Cash
Settlement shall obligate the Holder of the related Corporate Units 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
the case may be. Each Purchase Contract evidenced hereby which is settled
through Early Settlement following a Cash Merger pursuant to Section 5.7(b)(2)
of the Purchase Agreement shall obligate the Holder of the related Corporate
Units to purchase at the Purchase Price, and the Company to sell, a number of
newly issued shares of Common Stock equal to the Settlement Rate in effect
immediately prior to the Cash Merger (as such Settlement Rate may be adjusted
pursuant to Section 5.7(b)(1) of the Purchase Contract Agreement).

         The "Applicable Market Value" means the average of the Closing Price
per share of Common Stock on each of the 20 consecutive Trading Days ending on
(a) the third Trading Day immediately preceding the Purchase Contract Settlement
Date or (b) for purposes of determining cash payable in lieu of fractional
shares in connection with an Early Settlement pursuant to Section 5.11 of the
Purchase Contract Agreement, the third Trading Day immediately preceding the
relevant Early Settlement Date or (c) for the purposes of clause (2) of Section
5.7(b) of the Purchase Contract Agreement, the third Trading Day immediately
preceding the Cash Merger 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 any such date; or, if the Common Stock is not
listed for trading on the NYSE on any such date, the closing sale price as
reported in the composite transactions for the principal United States national
or regional

                                      A-5

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 sale price of the Common Stock as reported by the
Nasdaq National 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 Closing Price means the market value of the Common Stock
on the date 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 Corporate Unit 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 Notes of such Holder or of the
appropriate Applicable Ownership Interest in the Treasury Portfolio. Unless a
Tax Event Redemption, a Successful Initial Remarketing or a Successful Secondary
Remarketing has occurred, a Holder of Corporate Units 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 Notes held by the Collateral Agent. Unless a Tax Event Redemption, a
Successful Initial Remarketing or a Successful Secondary 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, a Successful Initial Remarketing or a Successful Secondary
Remarketing has occurred, a Holder of Corporate Units 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 (i) of the definition of
such term) in the Treasury Portfolio.

         If, as provided in the Purchase Contract Agreement, (i) upon the
occurrence of a Failed Final Remarketing (unless the Holder of this Certificate
has exercised the Put Option or elected Cash Settlement) or (ii) if a Holder
notifies the Agent of its intention to effect a Cash Settlement but fails to
deliver the purchase price in cash on or prior to the Business Day immediately
preceding the Purchase Contract Settlement Date, the Collateral Agent, for the
benefit of the Company, exercises its rights as a secured creditor with respect
to the pledged Notes related to this Corporate Unit Certificate, any accrued and
unpaid interest on such pledged Notes will become payable by the Company to the
Holder of the Corporate Unit Certificate in the manner provided for in the
Purchase Contract Agreement.

         The Company shall not be obligated to issue any shares of Common Stock
in respect of a Purchase Contract or deliver any certificates therefor to the
Holder unless it shall have received payment 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
Notes. Upon receipt of notice of any

                                      A-6

meeting at which holders of Notes are entitled to vote or upon the solicitation
of consents, waivers or proxies of holders of Notes, the Agent shall, as soon as
practicable thereafter, mail to the Corporate Unit Holders a notice (a)
containing such information as is contained in the notice or solicitation, (b)
stating that each Corporate Unit Holder on the record date set by the Agent
therefor (which, to the extent possible, shall be the same date as the record
date for determining the holders of Notes entitled to vote) shall be entitled to
instruct the Agent as to the exercise of the voting rights pertaining to the
Notes constituting a part of such holder's Corporate Units and (c) stating the
manner in which such instructions may be given. Upon the written request of the
Corporate Unit 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 Notes as to which any
particular voting instructions are received. In the absence of specific
instructions from the Holder of a Corporate Unit, the Agent shall abstain from
voting the Notes evidenced by such Corporate Units.

         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 an amount equal to the aggregate Redemption Amount
for the Notes that are components of Corporate Units to purchase, on behalf of
the Holders of Corporate Units, the Treasury Portfolio and promptly remit the
remaining portion of such Redemption Amount, if any to the Agent for payment to
the Holders of such Corporate Units.

         Upon the occurrence of a Successful Initial Remarketing or Successful
Secondary 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 Corporate Units, 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 or Successful
Secondary Remarketing to the Agent for payment to the Holders of such Corporate
Units.

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

         Upon the occurrence of a Successful Final Remarketing, pursuant to the
terms of the Remarketing Agreement, the Remarketing Agent will remit the entire
amount of the proceeds from such Successful Final Remarketing to the Collateral
Agent after deducting the Remarketing Fee. The portion of the entire proceeds
which is equal to the aggregate principal amount of the remarketed Notes will
automatically be applied by the Collateral Agent, in accordance with the Pledge
Agreement, to satisfy in full the obligations of the Holder of this Corporate
Unit to pay the Purchase Price for the shares of Common Stock under the related
Purchase Contracts on the Purchase Contract Settlement Date. With respect to
Notes that are part of Corporate Units, any proceeds in excess of those required
to pay the Purchase Price for the Purchase Contracts related to such Corporate
Units and the Remarketing Fee will be remitted to the Agent for payment to the
Holders of such Corporate Units. A Holder of this Corporate Unit whose Notes are
so remarketed will not otherwise be responsible with respect to such Notes for
the payment of any Remarketing Fee in connection therewith.

                                      A-7

         Following the occurrence of a Failed Final Remarketing, the holder of
the Notes will have a Put Option with regard to the Notes, and, if that Put
Option is not exercised by the Holders, the Company will, in accordance with the
terms of the Pledge Agreement, at its election, (a) direct the Collateral Agent
to dispose of such Holder's Notes in accordance with applicable law or (b) the
Company will either retain and cancel the Notes or cause the Notes to be sold in
one or more public or private sales, in either case, in full satisfaction of
such Holder's obligations under the Purchase Contracts. The Company will cause a
notice of such Failed Final Remarketing to be published on the second Business
Day immediately preceding the Purchase Contract Settlement Date in an Authorized
Newspaper.

         If a Holder of this Certificate has exercised the Put Option but has
not otherwise settled the Purchase Contracts in cash by the close of business on
the Business Day immediately prior to the Purchase Contract Settlement Date, the
put price will be applied by the Collateral Agent, in accordance with the terms
of the Pledge Agreement, to satisfy in full the obligations of the Holder to pay
the Purchase Price for the shares of Common Stock under the related Purchase
Contracts on the Purchase Contract Settlement Date.

         The Corporate Unit Certificates are issuable only in registered form
and only in denominations of a single Corporate Unit and any integral multiple
thereof. The transfer of any Corporate Unit Certificate will be registered and
Corporate Unit Certificates may be exchanged as provided in the Purchase
Contract Agreement. The Corporate Units Registrar may require a Holder, among
other things, to furnish appropriate endorsements and transfer documents
permitted by the Purchase Contract Agreement. No service charge shall be
required for any such registration of transfer or exchange, but the Company and
the Agent may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. A Holder who elects to
substitute Treasury Securities for Notes or the appropriate Applicable Ownership
Interest in the Treasury Portfolio, thereby creating Treasury Units, shall be
responsible for any fees or expenses payable in connection therewith. Except as
provided in the Purchase Contract Agreement, for so long as the Purchase
Contract underlying a Corporate Unit remains in effect, such Corporate Unit
shall not be separable into its constituent parts, and the rights and
obligations of the Holder of such Corporate Unit in respect of Notes or the
appropriate Applicable Ownership Interest in the Treasury Portfolio, as the case
may be, and the Purchase Contract constituting such Corporate Unit may be
transferred and exchanged only as a Corporate Unit. A Holder of a Corporate Unit
may create a Treasury Unit at any time prior to the seventh Business Day
immediately preceding the Purchase Contract Settlement Date by delivering to the
Collateral Agent Treasury Securities in an aggregate principal amount equal to
the aggregate principal amount of the pledged Notes or the appropriate
Applicable Ownership Interest (as specified in clause (i) of the definition of
such term) in the Treasury Portfolio, as the case may be, in exchange for the
release of such pledged Notes or the appropriate Applicable Ownership Interest
in 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 "Treasury Unit". A Holder may make such Collateral Substitution at any time
prior to the seventh Business Day immediately preceding the Purchase Contract
Settlement Date and only in integral multiples of 20 Corporate Units for the
same multiple of 20 Treasury Units; provided that if a Tax Event Redemption, a
Successful Initial Remarketing or a Successful Secondary Remarketing has
occurred and the Treasury Portfolio has become a component of the Corporate
Units, a Holder may make such Collateral Substitutions at any time prior to the
second Business Day immediately preceding the Purchase Contract Settlement Date
and only in integral multiples of 32,000 Corporate Units for the same multiple
of 32,000 Treasury Units.

                                      A-8

         A Holder of Treasury Units may recreate Corporate Units at any time
prior to the seventh Business Day immediately preceding the Purchase Contract
Settlement Date by delivering to the Collateral Agent Notes or the appropriate
Applicable Ownership Interest in the Treasury Portfolio, with an aggregate
principal amount, in the case of such Notes, or with the appropriate Applicable
Ownership Interest (as specified in clause (i) of the definition of such term)
in the Treasury Portfolio, in the case of such appropriate Applicable Ownership
Interest in 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 a Corporate Unit may
be effected at any time prior to the seventh Business Day immediately preceding
the Purchase Contract Settlement Date and only in multiples of 20 Treasury Units
for the same multiple of 20 Corporate Units; provided that if a Tax Event
Redemption, a Successful Initial Remarketing or a Successful Secondary
Remarketing has occurred and the Treasury Portfolio has become a component of
the Corporate Units, a Holder may make such substitution at any time on or prior
to the second Business Day immediately preceding the Purchase Contract
Settlement Date and only in integral multiples of 32,000 Treasury Units for the
same multiple of 32,000 Corporate Units.

         Notwithstanding the foregoing, a Holder of Corporate Units may not
create Treasury Units and a Holder of Treasury Units may not recreate Corporate
Units during the period commencing on the fourth Business Day immediately prior
to the Initial Remarketing Date (and, upon a Failed Initial Remarketing, prior
to the Secondary Remarketing Date) and ending on the fourth Business Day
following the Initial Remarketing Date (and, upon a Failed Initial Remarketing,
following the Secondary Remarketing Date).

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

         The Company shall have the right, at any time prior to the Purchase
Contract Settlement Date, to defer the payment of any or all of the Contract
Adjustment Payments, if any, otherwise payable on any Payment Date, but only if
the Company shall give the Holders and the Agent written notice of its election
to defer such payment (specifying the amount to be deferred) as provided in the
Purchase Contract Agreement. Any Contract Adjustment Payments, if any, so
deferred shall, to the extent permitted by law, bear additional Contract
Adjustment Payments thereon at the rate of 9% per year (computed on the basis of
a 360-day year of twelve 30-day months), compounded quarterly on each succeeding
Payment Date, until paid in full (such deferred installments of contract
Adjustment Payments, if any, together with the additional Contract Adjustment
Payments accrued thereon, are referred to herein as the "Deferred Contract
Adjustment Payments"). Deferred Contract Adjustment Payments, if any, shall be
due on the next succeeding Payment Date except to the extent that payment is
deferred pursuant to the Purchase Contract Agreement. No Contract Adjustment
Payments, if any, may be deferred to a date that is on or after the Purchase
Contract Settlement Date and no such deferral period may end other than on a
Payment Date.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments, if any, on the Purchase Contracts until a Payment Date
prior to the Purchase Contract Settlement Date, then all Deferred Contract
Adjustment Payments, if any, shall be payable to the

                                      A-9

registered Holders as of the close of business on the Record Date immediately
preceding such Payment Date.

         In the event that the Company elects to defer the payment of Contract
Adjustment Payments, if any, on the Purchase Contracts until the Purchase
Contract Settlement Date, the Holder of this Corporate Unit Certificate will
receive on the Purchase Contract Settlement Date, in lieu of a cash payment, a
number of shares of Common Stock (in addition to the number of shares of Common
Stock equal to the Settlement Rate) equal to (x) the aggregate amount of
Deferred Contract Adjustment Payments payable to the Holder of this Corporate
Unit Certificate divided by (y) the Applicable Market Value.

         In the event the Company exercises its option to defer the payment of
Contract Adjustment Payments, if any, then, until the Deferred Contract
Adjustment Payments have been paid, the Company shall not, and shall not permit
any of its subsidiaries to, declare or pay dividends on, make distributions with
respect to, or redeem, purchase or acquire, or make a liquidation payment with
respect to, any capital stock of the Company other than: (i) purchases,
redemptions or acquisitions of shares of capital stock of the Company in
connection with any employment contract, benefit plan or other similar
arrangement with or for the benefit of employees, officers or directors or a
stock purchase or dividend reinvestment plan, or the satisfaction by the Company
of its obligations pursuant to any contract or security outstanding on the date
of such event; (ii) as a result of a reclassification of the Company's capital
stock or the exchange or conversion of one class or series of the Company's
capital stock for another class or series of the Company's capital stock; (iii)
the purchase of fractional interests in shares of the Company's capital stock
pursuant to the conversion or exchange provisions of such capital stock or the
security being converted or exchanged; (iv) dividends or distributions in
capital stock of the Company (or rights to acquire capital stock) or
repurchases, acquisitions or redemptions of capital stock in connection with the
issuance or exchange of capital stock (or securities convertible into or
exchangeable for shares of capital stock of the Company); (v) redemptions,
exchanges or repurchases of any rights outstanding under a shareholder rights
plan or the declaration or payment thereunder of a dividend or distribution of
or with respect to rights in the future; or (vi) mandatory sinking fund payments
with respect to any series of preferred stock of the Company; provided that the
aggregate stated value of all such series outstanding at the time of such
payment does not exceed 5% of the aggregate of (1) the total principal amount of
all then outstanding bonds or other securities representing secured indebtedness
issued or assumed by the Company and (2) the Company's capital and surplus to be
stated on the Company's books of account after giving effect to such payment;
provided that any moneys deposited into any sinking fund and not in violation of
this clause (vi) may thereafter be applied to the purchase or redemption of such
preferred stock in accordance with the terms of such sinking fund without regard
to the foregoing restrictions.

         The Purchase Contracts and all obligations and rights of the Company
and the Holders thereunder, including, without limitation, the rights of the
Holders to receive and the obligation of the Company to pay Contract Adjustment
Payments, if any, or any Deferred Contract Adjustment Payments, and the rights
and obligations of Holders to purchase Common Stock, shall immediately and
automatically terminate, without the necessity of any notice or action by any
Holder, the Agent or the Company, if, on or prior to the 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 Corporate Units
Register. Upon and after the occurrence of a Termination Event, the Collateral
Agent shall release the Notes or the appropriate Applicable

                                      A-10

Ownership Interest in the Treasury Portfolio, as the case may be, from the
Pledge in accordance with the provisions of the Pledge Agreement.

         Subject to and upon compliance with the provisions of the Purchase
Contract Agreement, at the option of the Holder thereof, Purchase Contracts
underlying Securities may be settled early ("Early Settlement") as provided in
the Purchase Contract Agreement. In order to exercise the right to effect Early
Settlement with respect to any Purchase Contracts evidenced by this Corporate
Unit Certificate, the Holder of this Corporate Unit Certificate shall deliver to
the Agent at the Corporate Trust Office an Election to Settle Early form set
forth below and any other documents requested by the Agent duly completed and
accompanied by payment in the form of immediately available funds payable to the
order of the Company in an amount (the "Early Settlement Amount") equal to (i)
the product of (A) $50 and (B) the number of Purchase Contracts with respect to
which the Holder has elected to effect Early Settlement, plus (ii) if such
delivery is made with respect to any Purchase Contracts during the period from
the close of business on any Record Date for any Payment Date to the opening of
business on such Payment Date, an amount equal to the Contract Adjustment
Payments payable on such Payment Date with respect to such Purchase Contracts.

         Upon Early Settlement of Purchase Contracts by a Holder of the related
Securities, the Notes or the appropriate Applicable Ownership Interest (as
specified in clause (i) of the definition of such term) in the Treasury
Portfolio, as the case may be, underlying such Securities shall be released from
the Pledge as provided in the Pledge Agreement and the Holder shall be entitled
to receive a number of shares of Common Stock on account of each Purchase
Contract forming part of a Corporate Unit as to which Early Settlement is
effected equal to 1.7218 shares of Common Stock per Purchase Contract (the
"Early Settlement Rate"). The Early Settlement Rate shall be adjusted in the
same manner and at the same time as the Settlement Rate is adjusted as provided
in the Purchase Contract Agreement.

         Upon registration of transfer of this Corporate Unit 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 Corporate Unit
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 Corporate Unit Certificate, by its acceptance
hereof, authorizes the Agent to enter into and perform the related Purchase
Contracts forming part of the Corporate Units 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 Notes or the appropriate Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, underlying this Corporate Unit
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 Notes or
the appropriate Applicable Ownership Interest (as specified in clause (i) of the
definition of such term) in the Treasury Portfolio on the Purchase Contract
Settlement Date shall be paid by the Collateral

                                      A-11

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.

         The Holder of this Corporate Unit Certificate, by its acceptance
hereof, agrees to treat itself as owner of the related Notes or Applicable
Ownership Interest in the Treasury Portfolio, as the case may be, and to treat
the Notes as indebtedness for all tax purposes.

         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.

         Prior to due presentment of this Certificate for registration of
transfer, the Company, the Agent and its Affiliates and any agent of the Company
or the Agent may treat the Person in whose name this Corporate Unit Certificate
is registered as the owner of the Corporate Units evidenced hereby for the
purpose of receiving payments of interest payable quarterly on the Notes or on
the maturing quarterly interest strips of the Treasury Portfolio, as applicable,
receiving payments of Contract Adjustment Payments, if any, and any Deferred
Contract Adjustment Payments, performance of the Purchase Contracts and for all
other purposes whatsoever, 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.

                                      A-12

Number of Treasury Units _______

                                9% TREASURY UNITS

                  This Treasury Unit Certificate certifies that ___________ is
the registered Holder of the number of Treasury Units set forth above. Each
Treasury Unit represents (i) a 1/20, or 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 The St. Paul Companies, Inc., a Minnesota corporation
(the "Company", which term, as used herein, includes its successors pursuant to
the Purchase Contract Agreement). 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 Treasury Unit evidenced hereby have been pledged to
the Collateral Agent, for the benefit of the Company, to secure the obligations
of the Holder under the Purchase Contract comprising a portion of such Treasury
Units.

                  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 Treasury Units to the accounts designated by them in writing for such
purpose no later than 11:00 a.m., New York City time, on the Business Day such
payment is received by the Collateral Agent (provided that in the

- ------------------
* To be inserted in Global Certificates only

                                      B-1

event such payment is received by the Collateral Agent on a day that is not a
Business Day or after 10:30 a.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
Treasury Units of which such pledged Treasury Securities are a part under the
Purchase Contracts forming a part of such Treasury Units.

                  Each Purchase Contract evidenced hereby obligates the Holder
of this Treasury Unit Certificate to purchase, and the Company to sell, on
August 16, 2005 (the "Purchase Contract Settlement Date"), at a price equal to
$50 (the "Stated Amount"), a number of newly issued shares of class A common
stock, without 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 Treasury Units of which such Purchase Contract is a part, all as
provided in the Purchase Contract Agreement and more fully described on the
reverse hereof. The purchase price (the "Purchase Price") for the shares of
Common Stock purchased pursuant to each Purchase Contract evidenced hereby, it
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.

                  The Company shall pay on each Payment Date in respect of each
Purchase Contract forming part of a Treasury Unit evidenced hereby an amount
(the "Contract Adjustment Payments") equal to 3.75% per year of the Stated
Amount, computed on the basis of a 360-day year of twelve 30-day months, subject
to deferral at the option of the Company as provided in the Purchase Contract
Agreement and more fully described on the reverse hereof. Such Contract
Adjustment Payments, if any, shall be payable to the Person in whose name this
Treasury Unit Certificate (or a Predecessor Treasury Unit Certificate) is
registered at the close of business on the Record Date for such Payment Date.

                  Contract Adjustment Payments, if any, will be payable at the
Corporate Trust Office of the Agent and at the New York Office or, at the option
of the Company, by check mailed to the address of the Person entitled thereto as
such address appears on the Treasury Units Register or by wire transfer to the
account designated by such Person by prior written notice.

                  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 Corporate Unit 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.

                  IN WITNESS WHEREOF, the Company has caused this instrument to
be duly executed.

Dated:


                                      B-3

                 (Form of Reverse of Treasury Unit Certificate)

                  Each Purchase Contract evidenced hereby is governed by a
Purchase Contract Agreement, dated as of July 31, 2002 (as may be supplemented
from time to time, the "Purchase Contract Agreement"), between the Company and
JPMorgan Chase Bank, as Purchase Contract Agent (including its successors
thereunder, herein called the "Agent"), to which 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 Treasury Unit 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 Treasury Unit 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
$29.04 (the "Threshold Appreciation Price"), 1.7218 shares of Common Stock per
Purchase Contract, (b) if the Applicable Market Value is less than the Threshold
Appreciation Price but is greater than $24.20 (the "Reference Price"), the
number of shares of Common Stock per Purchase Contract equal to the Stated
Amount divided by the Applicable Market Value and (c) if the Applicable Market
Value is less than or equal to the Reference Price, 2.0661 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 (other than an Early Settlement following a Cash Merger
pursuant to Section 5.7(b)(2) of the Purchase Contract Agreement) shall obligate
the Holder of the related Treasury Units 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. Each Purchase Contract evidenced hereby which is
settled through Early Settlement following a Cash Merger pursuant to Section
5.7(b)(2) of the Purchase Agreement shall obligate the Holder of the related
Treasury Units to purchase at the Purchase Price, and the Company to sell, a
number of newly issued shares of Common Stock equal to the Settlement Rate in
effect immediately prior to the Cash Merger (as such Settlement Rate may be
adjusted pursuant to Section 5.7(b)(1) of the Purchase Contract Agreement).

                  The "Applicable Market Value" means the average of the Closing
Price per share of Common Stock on each of the 20 consecutive Trading Days
ending on (a) the third Trading Day immediately preceding the Purchase Contract
Settlement Date or (b) for purposes of determining cash payable in lieu of
fractional shares in connection with an Early Settlement pursuant to Section
5.11 of the Purchase Contract Agreement, the third Trading Day immediately
preceding the relevant Early Settlement Date or (c) for the purposes of clause
(2) of Section 5.7(b) of the Purchase Contract Agreement, the third Trading Day
immediately preceding the Cash Merger 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

                                      B-4

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 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 Closing Price means the market value of the Common Stock on the
date 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 Treasury Unit 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 Treasury Units equal to the Stated Amount to
the purchase of the Common Stock. A Holder of Treasury Units 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 Treasury Unit Certificates are issuable only in registered
form and only in denominations of a single Treasury Unit and any integral
multiple thereof. The transfer of any Treasury Unit Certificate will be
registered and Treasury Unit Certificates may be exchanged as provided in the
Purchase Contract Agreement. The Treasury Units Registrar may require a Holder,
among other things, to furnish appropriate endorsements and transfer documents
permitted by the Purchase Contract Agreement. No service charge shall be
required for any such registration of transfer or exchange, but the Company and
the Agent may require payment of a sum sufficient to cover any tax or other
governmental charge payable in connection therewith. A Holder who elects to
substitute Notes or the appropriate Applicable Ownership Interest in the
Treasury Portfolio, as the case may be, for Treasury Securities, thereby
recreating Corporate Units, shall be responsible for any fees or expenses
payable in connection therewith. Except as provided in the Purchase Contract
Agreement, for so long as the Purchase Contract underlying a Treasury Unit
remains in effect, such Treasury Unit shall not be separable into its
constituent parts, and the rights and obligations of the Holder of such Treasury
Unit in respect of the Treasury Security and the Purchase Contract constituting
such Treasury Unit may be transferred and exchanged only as a Treasury Unit. A
Holder of Treasury Units may recreate Corporate Units at any time prior to the
seventh Business Day immediately preceding the Purchase Contract Settlement Date
by delivering to the Collateral Agent Notes or the appropriate Applicable
Ownership Interest in the Treasury Portfolio, with an aggregate principal
amount, in the case of such Notes, or with the appropriate Applicable Ownership
Interest (as specified in clause (i) of the definition of such term) in the
Treasury Portfolio, in the case of such appropriate Applicable Ownership
Interest in 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. From and after such substitution, the
Security for which such pledged Notes or appropriate Applicable Ownership
Interest in the Treasury Portfolio, as the case may be, secures the Holder's


                                      B-5

obligation under the Purchase Contract shall be referred to as a "Corporate
Unit". A Holder may make such a substitution at any time prior to the seventh
Business Day immediately preceding the Purchase Contract Settlement Date and
only in integral multiples of 20 Treasury Units for the same multiple of 20
Corporate Units; provided that if a Tax Event Redemption, Successful Initial
Remarketing or Successful Secondary Remarketing has occurred and the Treasury
Portfolio has become a component of the Corporate Units, a Holder may make such
substitution at any time on or prior to the second Business Day immediately
preceding the Purchase Contract Settlement Date and only in integral multiples
of 32,000 Treasury Units for the same multiple of 32,000 Corporate Units.

                  A Holder of a Corporate Unit may create a Treasury Unit any
time prior to the seventh Business Day immediately preceding the Purchase
Contract Settlement Date by delivering to the Collateral Agent Treasury
Securities in an aggregate principal amount of the pledged Notes or the
appropriate Applicable Ownership Interest (as specified in clause (i) of the
definition of such term) in the Treasury Portfolio, as the case may be, in
exchange for the release of such pledged Notes or the appropriate Applicable
Ownership Interest in 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 Treasury Unit may be effected at any time prior to the
seventh Business Day immediately preceding the Purchase Contract Settlement Date
and only in multiples of 20 Corporate Units for the same multiple of 20 Treasury
Units; provided if a Tax Event Redemption or a Successful Initial Remarketing
has occurred and the Treasury Portfolio has become a component of the Corporate
Units, a Holder may make such Collateral Substitution at any time on or prior to
the second Business Day immediately preceding the Purchase Contract Settlement
Date and only in integral multiples of 32,000 Corporate Units for the same
multiple of 32,000 Treasury Units.

                  Notwithstanding the foregoing, a Holder of Corporate Units may
not create Treasury Units and a Holder of Treasury Units may not recreate
Corporate Units during the period commencing on the fourth Business Day
immediately prior to the Initial Remarketing Date (and, upon a Failed Initial
Remarketing, prior to the Secondary Remarketing Date) and ending on the fourth
Business Day following the Initial Remarketing Date (and, upon a Failed Initial
Remarketing, following the Second Remarketing Date).

                  Subject to the next succeeding paragraph, the Company shall
pay, on each Payment Date, the Contract Adjustment Payments, if any, payable in
respect of each Purchase Contract to the Person in whose name the Treasury Unit
Certificate evidencing such Purchase Contract is registered at the close of
business on the Record Date for such Payment Date. Contract Adjustment Payments,
if any, will be payable at the Corporate Trust Office of the Agent and the New
York Office or, at the option of the Company, by check mailed to the address of
the Person entitled thereto at such address as it appears on the Treasury Units
Register.

                  The Company shall have the right, at any time prior to the
Purchase Contract Settlement Date, to defer the payment of any or all of the
Contract Adjustment Payments, if any, otherwise payable on any Payment Date, but
only if the Company shall give the Holders and the Agent written notice of its
election to defer such payment (specifying the amount to be deferred) as
provided in the Purchase Contract Agreement. Any Contract Adjustment Payments,
if any, so deferred shall, to the extent permitted by law, bear additional
Contract Adjustment Payments thereon at the rate of 9% per year (computed on the
basis of a 360-day year of twelve 30 day months), compounded quarterly on each
succeeding Payment Date, until paid in full (such deferred installments of
Contract Adjustment Payments, if any, together with the additional Contract
Adjustment Payments accrued thereon, are referred to herein as the "Deferred
Contract Adjustment Payments"). Deferred Contract Adjustment Payments, if any,
shall be due on the next succeeding Payment Date except to the extent that
payment is deferred pursuant to the

                                      B-6

Purchase Contract Agreement. No Contract Adjustment Payments, if any, may be
deferred to a date that is on or after the Purchase Contract Settlement Date and
no such deferral period may end other than on a Payment Date.

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

                  In the event that the Company elects to defer the payment of
Contract Adjustment Payments, if any, on the Purchase Contracts until the
Purchase Contract Settlement Date, the Holder of this Treasury Unit Certificate
will receive on the Purchase Contract Settlement Date, in lieu of a cash
payment, a number of shares of Common Stock (in addition to the number of shares
of Common Stock equal to the Settlement Rate) equal to (x) the aggregate amount
of Deferred Contract Adjustment Payments payable to the Holder of this Treasury
Unit Certificate divided by (y) the Applicable Market Value.

                  In the event the Company exercises its option to defer the
payment of Contract Adjustment Payments, if any, then, until the Deferred
Contract Adjustment Payments have been paid, the Company shall not, and shall
not permit any of its subsidiaries to, declare or pay dividends on, make
distributions with respect to, or redeem, purchase or acquire, or make a
liquidation payment with respect to, any capital stock of the Company other
than: (i) purchases, redemptions or acquisitions of shares of capital stock of
the Company in connection with any employment contract, benefit plan or other
similar arrangement with or for the benefit of employees, officers or directors
or a stock purchase or dividend reinvestment plan, or the satisfaction by the
Company of its obligations pursuant to any contract or security outstanding on
the date of such event; (ii) as a result of a reclassification of the Company's
capital stock or the exchange or conversion of one class or series of the
Company's capital stock for another class or series of the Company's capital
stock; (iii) the purchase of fractional interests in shares of the Company's
capital stock pursuant to the conversion or exchange provisions of such capital
stock or the security being converted or exchanged; (iv) dividends or
distributions in capital stock of the Company (or rights to acquire capital

connection with the issuance or exchange of capital stock (or securities
convertible into or exchangeable for shares of capital stock of the Company) ;
(v) redemptions, exchanges or repurchases of any rights outstanding under a
shareholder rights plan or the declaration or payment thereunder of a dividend
or distribution of or with respect to rights in the future; or (vi) mandatory
sinking fund payments with respect to any series of preferred stock of the
Company; provided that the aggregate stated value of all such series outstanding
at the time of such payment does not exceed 5% of the aggregate of (1) the total
principal amount of all then outstanding bonds or other securities representing
secured indebtedness issued or assumed by the Company and (2) the Company's
capital and surplus to be stated on the Company's books of account after giving
effect to such payment; provided that any moneys deposited into any sinking fund
and not in violation of this clause (vi) may thereafter be applied to the
purchase or redemption of such preferred stock in accordance with the terms of
such sinking fund without regard to the foregoing restrictions.

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

                                      B-7

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 Treasury Units 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 Holder thereof, Purchase
Contracts underlying Securities may be settled early ("Early Settlement") as
provided in the Purchase Contract Agreement. In order to exercise the right to
effect Early Settlement with respect to any Purchase Contracts evidenced by this
Corporate Unit Certificate, the Holder of this Treasury Unit Certificate shall
deliver to the Agent at the Corporate Trust Office an Election to Settle Early
form set forth below and any other documents requested by the Agent duly
completed and accompanied by payment in the form of immediately available funds
payable to the order of the Company in an amount (the "Early Settlement Amount")
equal to (i) the product of (A) $50 times (B) the number of Purchase Contracts
with respect to which the Holder has elected to effect Early Settlement, plus
(ii) if such delivery is made with respect to any Purchase Contracts during the
period from the close of business on any Record Date for any Payment Date to the
opening of business on such Payment Date, an amount equal to the Contract
Adjustment Payments payable on such Payment Date with respect to such Purchase
Contracts.

                  Upon Early Settlement of Purchase Contracts by a Holder of the
related Securities the Pledged Treasury Securities underlying such Securities
shall be released from the Pledge as provided in the Pledge Agreement and the
Holder shall be entitled to receive a number of shares of Common Stock on
account of each Purchase Contract forming part of a Treasury Unit as to which
Early Settlement is effected equal to 1.7218 shares of Common Stock per Purchase
Contract (the "Early Settlement Rate"). The Early Settlement Rate shall be
adjusted in the same manner and at the same time as the Settlement Rate is
adjusted as provided in the Purchase Contract Agreement.

                  Upon registration of transfer of this Treasury Unit
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 Treasury Unit 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 Treasury Unit Certificate, by its
acceptance hereof, authorizes the Agent to enter into and perform the related
Purchase Contracts forming part of the Treasury Units 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 Treasury Unit 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

                                      B-8

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.

                  The Holder of this Treasury Unit Certificate, by its
acceptance hereof, agrees to treat itself as owner of the Applicable Ownership
Interest in the Treasury Securities.

                   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.

                  Prior to due presentment of this Certificate for registration
of transfer, the Company, the Agent and its Affiliates and any agent of the
Company or the Agent may treat the Person in whose name this Treasury Unit
Certificate is registered as the owner of the Treasury Units evidenced hereby
for the purpose of receiving payments on the Treasury Securities, receiving
payments of Contract Adjustment Payments, if any, and any Deferred Contract
Adjustment Payments, performance of the Purchase Contracts and for all other
purposes whatsoever, 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.
