registered on the Regular Record Date for such Interest Payment Date; provided
that interest payable on the Stated Maturity of principal as provided herein
shall be paid to the Person to whom principal is payable. Any such interest that
is not so punctually paid or duly provided for with respect to any Interest
Payment Date falling after a Stock Purchase Date will forthwith cease to be
payable to the Holders on such Regular Record Date and may either be paid to the
Person or Persons in whose name the Senior Notes are registered at the close of
business on a Special Record Date for the payment of such defaulted interest to
be fixed by the Trustee (in accordance with Section 307 of the Base Indenture),
notice whereof shall be given to Holders of the Senior Notes not less than ten
(10) days prior to such Special Record Date, or be paid at any time in any other
lawful manner not inconsistent with the requirements of any securities exchange,
if any, on which the Senior Notes may be listed, and upon such notice as may be
required by any such exchange, all as more fully provided in the Base Indenture.

                  Payment of the principal of and interest on the Senior Notes
shall be made at an Office or Agency of the Company or at the Office of the
Agent in The City of New York in such coin or currency of the United States of
America as at the time of payment is legal tender for payment of public and
private debts, with any such payment that is due on the Stated Maturity of any
Senior Notes being made upon surrender of such Senior Notes to the Office or
Agency of the Company or at the Office of the Agent in The City of New York.
Payments of interest will be made, subject to such surrender where applicable,
at the option of the Company, (i) by check mailed to the address of the Person
entitled thereto as such address shall appear in the Security Register or (ii)
by wire transfer at such place and to such account at a banking institution in
the United States as may be designated in writing to the Trustee at least
sixteen (16) days prior to the date for payment by the Person entitled hereto.
In the event that any date on which principal or

                                       8
<PAGE>

interest is payable on the Senior Notes is not a Business Day, then payment of
the principal or interest payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or payment in
respect of any such delay), in each case with the same force and effect as if
made on the date the payment was originally payable. However, if such Business
Day is in the next calendar year, then such payment will be made on the
preceding Business Day.

                  Section 204. Denominations. The Senior Notes shall be issued
in denominations of $50 and integral multiples of $50.

                  Section 205. Global Securities.

                  The Senior Notes that are part of Upper DECS will be issued
initially in the form of one or more Registered Securities in certificated,
definitive form, registered in the name of the Forward Purchase Contract Agent.
The Senior Notes that, in accordance with the Forward Purchase Contract
Agreement, are no longer part of the Upper DECS will be issued initially in the
form of one or more global securities (the "Global Securities") registered in
the name of DTC or its nominee. Except under the limited circumstances described
below or in Section 203 above, Senior Notes represented by such Global
Securities will not be exchangeable for, and will not otherwise be issuable as,
Senior Notes in definitive form. The Global Securities described above may not
be transferred except by DTC to a nominee of DTC or by a nominee of DTC to DTC
or another nominee of DTC or to a successor Depository or its nominee.

                  Owners of beneficial interests in such a Global Security will
not be considered the Holders thereof for any purpose under the Indenture, and
no Global Security representing a Senior Note shall be exchangeable, except for
another Global Security of like denomination and tenor to be registered in the
name of DTC or its nominee or to a successor Depository or its nominee or except
as described below. The rights of owners of beneficial interests in such a
Global Security shall be exercised only through DTC.

                  A Global Security shall be exchangeable for Senior Notes
registered in the names of persons other than DTC or its nominee only if (i) DTC
notifies the Company that it is unwilling or unable to continue as a Depository
for such Global Security and no successor Depository shall have been appointed
by the Company within 90 days of receipt by the Company of such notification, or
if at any time DTC ceases to be a clearing agency registered under the
Securities Exchange Act of 1934 at a time when DTC is required to be so
registered to act as such Depository and no successor Depository shall have been
appointed by the Company within 90 days after it becomes aware of such
cessation, or (ii) the Company in its sole discretion determines that it no
longer has any senior debt securities represented by global securities or that
it will permit a Global Security to be exchangeable or an Event of Default under
the Indenture has occurred and is continuing. Any Global Security that is
exchangeable pursuant to the preceding sentence shall be exchangeable for Senior
Notes registered in such names as DTC shall direct.

                  Section 206. Remarketing.

                  The Pledged Notes comprising part of Upper DECS and the
Separate Notes of holders of Separate Notes that have elected to participate in
the Remarketing shall be remarketed

                                       9
<PAGE>

by the Remarketing Agent on the Remarketing Date or Accelerated Remarketing
Date, as applicable. A Holder of Upper DECS may elect not to participate in a
Remarketing and retain the Senior Notes underlying such Upper DECS by notifying
the Forward Purchase Contract Agent of such election and delivering the Opt-out
Treasury Consideration to the Forward Purchase Contract Agent not later than
10:00 a.m. on the fourth Business Day prior to the Remarketing Date or the
Accelerated Remarketing Date, as applicable (or, in the case of a Failed
Remarketing, not later than 10:00 a.m. on the fourth Business Day immediately
prior to the subsequent Remarketing Period). Upon receipt thereof by the Forward
Purchase Contract Agent, the Forward Purchase Contract Agent shall deliver such
Opt-out Treasury Consideration to the Collateral Agent, which will, for the
benefit of the Company, thereupon apply such Opt-out Treasury Consideration to
secure such Holder's obligations under the Forward Purchase Contracts. On the
first Business Day immediately preceding the Remarketing Date or the Accelerated
Remarketing Date (or, in the case of a Failed Remarketing, the subsequent
Remarketing Period), the Collateral Agent, pursuant to the terms of the Pledge
Agreement, will deliver the Pledged Notes to the Forward Purchase Contract
Agent. Within three Business Days following any Remarketing Period (A) if the
Remarketing was successful, the Forward Purchase Contract Agent shall distribute
such Notes to the Holders thereof and (B) if there was a Failed Remarketing, the
Forward Purchase Contract Agent will deliver such Notes to the Collateral Agent,
which will, for the benefit of the Company, thereupon apply such Notes to secure
such Holders' obligations under the Forward Purchase Contracts and return any
Opt-out Treasury Consideration delivered by such Holders to such Holders. A
Holder that does not so deliver the Opt-out Treasury Consideration or has not
settled the related Purchase Contract through a Cash Settlement or an Early
Settlement pursuant to Sections 5.2 and 5.7 of the Forward Purchase Contract
Agreement shall be deemed to have elected to participate in the Remarketing.

                  On the seventh Business Day prior to the Remarketing Date or
Accelerated Remarketing Date, the first day of any subsequent Remarketing Period
(or if a Secondary Acceleration Event has occurred, on the fifth Business Day
prior to the Accelerated Remarketing Date), the Company shall give Holders of
Upper DECS and Holders of Separate Notes notice of the Remarketing in an
Authorized Newspaper, including the specific U.S. Treasury security or
securities (including the CUSIP number and/or the principal terms of such
Treasury security or securities) that must be delivered by Holders of Upper DECS
that elect not to participate in the Remarketing pursuant to Section 5.2(g) of
the Forward Purchase Contract Agreement, no later than 10:00 a.m. (New York City
time) on the fourth Business Day preceding the Remarketing Date or Accelerated
Remarketing Date or the first day of any subsequent Remarketing Period, as
applicable. Not later than seven nor more than 15 calendar days prior to any
Remarketing Period, the Company shall request DTC (or any successor Clearing
Agency) to notify, directly or indirectly, each Beneficial Owner or Clearing
Agency Participant holding DECS and each Beneficial Owner of a Separate Note of
the Remarketing and of the procedures that must be followed in connection with
the Remarketing.

                  The Forward Purchase Contract Agent shall notify, by 10:00
a.m., New York City time, on the third Business Date preceding the Remarketing
Date or Accelerated Remarketing Date or the first day of any subsequent
Remarketing Period, as applicable, the Remarketing Agent and the Collateral
Agent of the aggregate number of Senior Notes of Upper DECS Holders to be
remarketed. On the third Business Day immediately preceding the Remarketing Date
or Accelerated Remarketing Date or the first day of any subsequent Remarketing
Period, as

                                       10
<PAGE>

applicable, no later than by 10:00 a.m. New York City time, pursuant to the
terms of the Pledge Agreement, the Custodial Agent will notify the Remarketing
Agent of the aggregate number of Separate Notes to be remarketed. On the third
Business Day immediately preceding the Remarketing Date or Accelerated
Remarketing Date or the first day of any subsequent Remarketing Period, as
applicable, the Collateral Agent and the Custodial Agent, pursuant to the terms
of the Pledge Agreement, will deliver for Remarketing to the Remarketing Agent
all Notes to be remarketed. Upon receipt of such notice from the Forward
Purchase Contract Agent and the Custodial Agent and such Notes from the
Collateral Agent and the Custodial Agent, the Remarketing Agent will, on the
Remarketing Date or Accelerated Remarketing Date, as applicable, use its
commercially reasonable best efforts to establish a Reset Rate pursuant to
clause (i) of the definition of Reset Rate and remarket such Senior Notes
pursuant to the Remarketing procedures in the Remarketing Agreement.

                  The right of each Holder of Senior Notes to have its Senior
Notes tendered for purchase will be limited to the extent that (i) the
Remarketing Agent conducts a Remarketing pursuant to the terms of the
Remarketing Agreement, (ii) the Remarketing Agent is able to find a purchaser or
purchasers for the tendered Senior Notes and (iii) such purchaser or purchasers
deliver the purchase price therefor to the Remarketing Agent.

                  If a successful Remarketing shall have occurred, the
Remarketing Agent will, in accordance with the Forward Purchase Contract
Agreement and the Remarketing Agreement, (i) deduct and retain for itself the
Remarketing Fee, (ii) use the proceeds from such successful Remarketing to
purchase the Agent-purchased Treasury Consideration with the CUSIP numbers, if
any, selected by the Remarketing Agent, described in clauses (1) and (2) of the
definition of Remarketing Value or clauses (i) and (ii) of the definition of
Accelerated Remarketing Value, as applicable, in the Forward Purchase Contract
Agreement related to the Senior Notes of Holders of Upper DECS or that were
remarketed, (iii) if any Separate Notes were remarketed, remit to the Collateral
Agent for payment to the Holders of such Separate Notes sold in the Remarketing
the remaining proceeds from such successful Remarketing attributable to the
Separate Notes and (iv) if there remain any proceeds from such successful
Remarketing, after the application of such proceeds as set forth in clauses (i)
through (iii) of this sentence, then remit such remaining proceeds to the
Forward Purchase Contract Agent for payment to the Holders of the Upper DECS
that were remarketed, on a pro rata basis, in accordance with the Remarketing
Agreement.

                  On or prior to the third Business Day following the
Remarketing Date or Accelerated Remarketing Date (in either case, if such
Remarketing is successful), or any Subsequent Remarketing Date, the Remarketing
Agent shall deliver such Agent-purchased Treasury Consideration to the Forward
Purchase Contract Agent, which shall thereupon deliver such Agent-purchased
Treasury Consideration to the Collateral Agent. The Collateral Agent, for the
benefit of the Company, will thereupon apply such Agent-purchased Treasury
Consideration, in accordance with the Pledge Agreement, to secure such Holders'
obligations under the Forward Purchase Contracts.

                  If a successful Remarketing occurs, by approximately 4:30 p.m.
(New York City time) on the Remarketing Date or Accelerated Remarketing Date, as
applicable, the Remarketing Agent shall advise, by telephone (promptly confirmed
in writing in the case of clause (i)):

                                       11
<PAGE>

                  (i) the Company, the Forward Purchase Contract Agent, the
Collateral Agent, the Securities Intermediary, DTC and the Trustee of the Reset
Rate determined in the Remarketing;

                  (ii) each purchaser (or the Depository Participant thereof) of
Senior Notes in the Remarketing of the Reset Rate and the number of Senior Notes
such purchaser is to purchase; and

                  (iii) each purchaser to give instructions to its Depository
Participant to pay the purchase price on the date of settlement for such
Remarketing in same day funds against delivery of the remarketed Senior Notes
purchased through the facilities of DTC.

                  If a Failed Remarketing occurs, the Remarketing Agent and the
Company, as applicable, shall take the following actions:

                  (i) the Remarketing Agent shall notify by telephone the
Company, the Forward Purchase Contract Agent, the Collateral Agent and the
Trustee, that a Failed Remarketing has occurred, whereupon the Company shall
notify the Clearing Agency, by telephone, that a Failed Remarketing has
occurred;

                  (ii) with respect to any Remarketing Period during which no
successful Remarketing occurred, the Company shall publish notice by means of
Bloomberg and Reuters newswires, such notice to be published no later than the
fourth Business Day following the end of such Remarketing Period; and

                  (iii) the Remarketing Agent shall remit, within three Business
Days following the end of a Remarketing Period which constituted a Failed
Remarketing or a Last Failed Accelerated Remarketing, the Pledged Notes that
were to be remarketed to the Collateral Agent and the Separate Notes that were
to be remarketed to the Custodial Agent, in each case other than Senior Notes
deemed purchased by the Company.

                  Holders of Senior Notes may make a contingent election by
delivering an opt-out notice to the Forward Purchase Contract Agent (an "Opt-Out
Notice"), substantially as set forth in an exhibit to the Senior Notes (the form
of which is attached as Exhibit A hereto), on or prior to the third Business Day
prior to a Stock Purchase Date that in the event a Last Failed Remarketing or
Last Failed Accelerated Remarketing occurs, such holders elect not to sell their
Senior Notes to the Company.

                  If upon a Last Failed Remarketing or a Last Failed Accelerated
Remarketing, the Collateral Agent delivers any Senior Notes to the Company in
full satisfaction of the Holder's obligation under the related Forward Purchase
Contracts, any accumulated and unpaid interest on such Notes will become payable
by the Company to the Forward Purchase Contract Agent for payment to the Holder
of the Upper DECS to which such Notes relate. Such payment will be made by the
Company on or prior to 11:00 a.m., New York City time, on the relevant Stock
Purchase Date in lawful money of the United States by certified or cashier's
check or wire transfer in immediately available funds payable to or upon the
order of the Forward Purchase

                                       12

Contract Agent. Upon the occurrence of a Last Failed Remarketing or Last Failed
Accelerated Remarketing, the Company will purchase on the relevant Stock
Purchase Date all Outstanding Senior Notes of all Holders, except Senior Notes
for which an Opt-Out Notice has been delivered to the Forward Purchase Contract
Agent in accordance with the preceding paragraph for an amount equal to the
Stated Amount of such Senior Notes plus, in the event of a repurchase on an
Accelerated Stock Purchase Date, an amount in cash equal to the value of the
Treasury securities described in clause (ii) of the definition of Accelerated
Remarketing Value (assuming, for this purpose, that the relevant Subsequent
Remarketing Date is the Accelerated Stock Purchase Date). The proceeds of the
sale of Senior Notes deemed to be submitted for sale to the Company shall be
paid (a) to the Collateral Agent on behalf of such holder to satisfy such
holder's obligation under the related Forward Purchase Contract if such Senior
Notes are part of an Upper DECS and (b) to the Holder of such Notes if the Notes
are Separate Notes. The Company will publish notice by means of Bloomberg and
Reuters newswires of any Remarketing Period during which no successful
Remarketing occurred, such notice to be published not later than the fourth
Business Day following the end of such Remarketing Period. The Company will
cause a notice of the Last Failed Remarketing or Last Failed Accelerated
Remarketing to be published on the fourth Business Day following the date of the
Last Failed Remarketing or Last Failed Accelerated Remarketing in an Authorized
Newspaper.

                  With respect to any Senior Notes which constitute part of
Upper DECS which are subject to the Last Failed Remarketing or Last Failed
Accelerated Remarketing, as applicable, or for which an Opt-Out Notice was
delivered, but for which no cash payment was delivered, the Collateral Agent for
the benefit of the Company reserves all of its rights as a secured party with
respect thereto and, subject to applicable law and Section 5.2(j) of the Forward
Purchase Contract Agreement, may, among other things, permit the Company to
cause the Senior Notes to be sold or to retain and cancel such Senior Notes, in
either case, in full satisfaction of the Holders' obligations under the Forward
Purchase Contracts.

                  Notwithstanding anything herein to the contrary, the Reset
Rate shall in no event exceed the maximum rate, if any, permitted by applicable
law.

                  In accordance with DTC's normal procedures, on the date of
settlement of such Remarketing or the relevant Stock Purchase Date, as
applicable, the transactions described above with respect to each Senior Notes
remarketed in the Remarketing shall be executed through DTC, and the accounts of
the respective Depository Participants shall be debited and credited and such
remarketed Senior Notes delivered by book entry as necessary to effect purchases
and sales of such remarketed Senior Notes. DTC shall make payment in accordance
with its normal procedures.

                  If any Holder of Senior Notes selling Senior Notes in the
Remarketing fails to deliver such Senior Notes, the direct or indirect
Depository Participant of such selling Holder and of any other Person who was to
have purchased Senior Notes in the Remarketing may deliver to any such other
Person an aggregate principal amount of Senior Notes that is less than the
aggregate principal amount of Senior Notes that otherwise was to be purchased by
such Person. In such event, the aggregate principal amount of Senior Notes to be
so delivered shall be

                                       13
<PAGE>

determined by such direct or indirect Depository Participant, and delivery of
such lesser aggregate principal amount of Senior Notes shall constitute good
delivery.

                  The Remarketing Agent is not obligated to purchase any Senior
Notes that otherwise would remain unsold in the Remarketing. Neither the Company
nor the Remarketing Agent shall be obligated in any case to provide funds to
make payment upon tender of the Senior Notes for Remarketing.

                  Under the Remarketing Agreement, the Company, in its capacity
as issuer of the Senior Notes, shall be liable for, and shall pay, any and all
costs and expenses incurred in connection with the Remarketing, other than the
Remarketing Fee.

                  The settlement procedures set forth herein, including
provisions for payment by purchasers of the remarketed Senior Notes in the
Remarketing, shall be subject to modification to the extent required by DTC or
if the book-entry system is no longer available for the remarketed Senior Notes
at the time of the Remarketing, to facilitate the Remarketing of the remarketed
Senior Notes in certificated form, and shall provide for the authentication and
delivery of Senior Notes in a principal amount equal to the unremarketed portion
of such Senior Notes. In addition, the Remarketing Agent may modify the
settlement procedures set forth herein in order to facilitate the settlement
process.

                  Section 207. Accelerated Remarketing. The Senior Notes shall
be subject to a Remarketing, in accordance with Section 206 hereof and Sections
5.2 and 5.9 of the Forward Purchase Contract Agreement, if an Initial
Acceleration Event occurs prior to the Scheduled Stock Purchase Date; provided,
however, that if such Initial Acceleration Event is solely the result of a
change in the then applicable Prompt Corrective Action Rules, the Forward
Purchase Contract Agent shall, if so instructed by the Company, delay the
Remarketing of the Senior Notes by 90 days after such Initial Acceleration
Event. If, before the expiration of the Grace Period, the Bank is notified or is
deemed to be notified in accordance with the Prompt Corrective Action Rules that
it is in the capital category "well capitalized" (as defined in the Prompt
Corrective Action Rules), the Accelerated Remarketing shall be cancelled. The
Senior Notes shall also be subject to a Remarketing, in accordance with Sections
5.2 and 5.9 of the Forward Purchase Contract Agreement, if a Secondary
Acceleration Event occurs prior to the Scheduled Stock Purchase Date.

                  In the event of a successful Accelerated Remarketing following
a Secondary Acceleration Event, Treasury securities as described in subclause
(ii) of the definition of Accelerated Remarketing Value will be released to the
Forward Purchase Contract Agent for the benefit of each holder of DECS (other
than Stripped DECS) when received.

                  Section 208. Optional Remarketing.

                  On or prior to the fourth Business Day immediately preceding
the Remarketing Date, any Accelerated Remarketing Date or the first day of any
subsequent Remarketing Period, but no earlier than the Interest Payment Date
immediately preceding the last Interest Payment Date before the relevant Stock
Purchase Date, holders of Separate Notes may elect to have their Separate Notes
remarketed by Transferring their Separate Notes and delivering a notice of such

                                       14
<PAGE>

election, substantially in the form of Exhibit C to the Pledge Agreement, to the
Custodial Agent. On the third Business Day immediately prior to the Remarketing
Date, any Accelerated Remarketing Date or the first day of any subsequent
Remarketing Period, by 10:00 a.m., New York City time, the Custodial Agent shall
notify the Remarketing Agent of the number of such Separate Notes to be
remarketed. The Custodial Agent will hold such Separate Notes in an account
separate from the Collateral Account. A holder of Separate Notes electing to
have its Separate Notes remarketed will also have the right to withdraw such
election by written notice to the Custodial Agent, substantially in the form of
Exhibit D to the Pledge Agreement, on or prior to the fourth Business Day
immediately preceding the applicable Remarketing Date, Accelerated Remarketing
Date or the first day of a subsequent Remarketing Period, upon which notice the
Custodial Agent will return such Separate Notes to such holder.

                  On the third Business Day immediately preceding the
Remarketing Date, any Accelerated Remarketing Date or the first day of any
subsequent Remarketing Period, the Custodial Agent at the written direction of
the Remarketing Agent will deliver to the Remarketing Agent for Remarketing all
Separate Notes delivered to the Custodial Agent pursuant to Section 4.5(d) of
the Pledge Agreement and not withdrawn pursuant to the terms thereof prior to
such date. If the holder of the Separate Notes delivers only such notice but not
the Separate Notes subject to such notice, then none of such holder's Separate
Notes shall be included in the Remarketing. Once the holder of Separate Notes
elects to participate in the Remarketing, such Separate Notes will be remarketed
in the Remarketing, unless such notice is properly withdrawn. In accordance with
Section 4.5(d) of the Pledge Agreement, upon the occurrence of a Failed
Remarketing or Failed Accelerated Remarketing, the Remarketing Agent will
promptly return such Separate Notes to the Custodial Agent for redelivery to
such holders of such Separate Notes.

                  Section 209. Sinking Fund. The Senior Notes shall not be
entitled to any sinking fund.

                  Section 210. Redemption and Repurchase. Except as provided in
Section 212, the Senior Notes shall not be redeemable prior to their Stated
Maturity. The Senior Notes are subject to mandatory repurchase by the Company in
certain events set forth in Section 206.

                  Section 211. Covenants. While Senior Notes remain Outstanding,
in the event that and so long as an Initial Acceleration Event or Secondary
Acceleration Event shall have occurred and be continuing the following covenants
shall apply:

         the Company or any of its Subsidiaries from the sale of credit card
         loans and other finance receivables pursuant to securitizations.

                  (b) None of the Company, the Bank or the Savings Bank will,

         being contested in good faith by appropriate proceedings for which
         adequate reserves (in the good faith judgment of management of the
         relevant entity) have been established;

                           (ii) Liens imposed by law (A) which are incurred in
         the ordinary course of business and (x) which do not in the aggregate
         materially detract from the value of such Receivables or Restricted
         Shares or materially impair the use thereof in the operation of the
         business of the Company or any of its Subsidiaries or (y) which are
         being contested in good faith by appropriate proceedings, which

         preventing the forfeiture or sale of the Receivables or Restricted
         Shares subject to such Lien or (B) which do not relate to the material
         liabilities of the Company and its Subsidiaries and do not in the
         aggregate materially detract from the value of the Receivables or
         Restricted Shares of the Company and its Subsidiaries taken as a whole;
         provided that no Lien permitted under this clause (b)(ii) may secure
         any obligation in an amount exceeding $50,000,000; and

                           (iii) (A) any pledge of Receivables to a Federal
         Reserve Bank made in the ordinary course of business to secure advances
         or (B) any other transaction undertaken to manage the liquidity
         position of the relevant entity.

                  (c) None of the Company, the Bank or the Savings Bank will

                  (d) The Company will not permit Tangible Net Worth with
respect to the Company on any date of determination to be less than the sum of
(i) $875,000,000 plus (ii) 40% of the Company's Cumulative Net Income as of the
last day of the fiscal quarter of the Company most recently ended plus (iii) 40%
of the Company's Cumulative Equity Proceeds as of that date of determination
plus (iv) the Upper DECS issued in connection with the Prospectus of the
Company, as supplemented by the final Prospectus Supplement, dated April 17,
2002.

                  (e) The Company will not permit the Double Leverage Ratio on
any date of determination to exceed 1.25 to 1.

                  (f) the Bank will not, nor will it permit any of its
Subsidiaries to, engage to any extent in any line or lines of business activity
other than as permitted by its charter;

                  (g) the Savings Bank will not, nor will it permit any of its
Subsidiaries to, engage to any extent in any line or lines of business activity
other than as permitted by its charter; and

                  (h) the Company will not, nor will it permit any of its
Subsidiaries to, engage to any material extent in any line or lines of business
activity other than consumer-oriented or consumer-related business activities
and database marketing activities, and other business activities to the extent
such other business activities are direct applications of the information based
strategies and related proprietary strategies used by the Company or its
Subsidiaries in the conduct its or their business.

                  Section 212. Tax Event Redemption.

                  If a Tax Event shall occur and be continuing, the Company may,
at its option, redeem the Senior Notes in whole (but not in part) at any time at
a price per Senior Note equal to the Redemption Price. Installments of interest
on the Senior Notes that are due and payable on or prior to the date of
redemption (the "Tax Event Redemption Date") will be payable to the Holders of
the Senior Notes registered as such at the close of business on the Business Day
next preceding such Tax Event Redemption Date. If, following the settlement of
the Forward Purchase Contracts and following the occurrence of a Tax Event, the
Company, at its option,

                                       17
<PAGE>

redeems the Senior Notes, the proceeds of the redemption will be payable in cash
to the Holders of the Senior Notes.

                  If the Company exercises its option to redeem the Senior Notes
following the occurrence of a Tax Event prior to the Remarketing Date or the
Accelerated Remarketing Date, or if there has not been a successful Remarketing
prior to the relevant Stock Purchase Date, the Company shall in the notice to
the Trustee pursuant to Section 105 of the Base Indenture specify the Redemption
Price. Upon the specification of the Redemption Price by the Company, the
Company shall appoint the Collateral Agent to acquire the Treasury Portfolio in
consultation with the Company and in accordance with the Forward Purchase
Contract Agreement. The Collateral Agent shall then apply, out of the aggregate
Redemption Price for the Senior Notes that are components of Upper DECS, an
amount equal to the aggregate Tax Event Redemption Principal Amount for the
Senior Notes that are components of Upper DECS to purchase on behalf of the
Holders of Upper DECS the Treasury Portfolio and promptly remit the remaining
portion, if any, of such aggregate Redemption Price to the Forward Purchase
Contract Agent for payment to the Holders of such Upper DECS. The Treasury
Portfolio will be substituted for the Pledged Notes, and will be pledged to the
Collateral Agent in accordance with the terms of the Pledge Agreement to secure
the obligation of each Holder of an Upper DECS to purchase the Common Stock
under the Forward Purchase Contract constituting a part of such Upper DECS.
Payment of the Redemption Price to Holders of Separate Notes shall be made in
cash on the Tax Event Redemption Date.

                  If a Tax Event Redemption occurs after a successful
Remarketing or the relevant Stock Purchase Date, payment of the Redemption Price
to each Holder of Senior Notes shall be made by the Trustee (subject to its
receipt of funds), no later than 12:00 noon, New York City time, on the Tax
Event Redemption Date, by check or wire transfer in immediately available funds
(provided the necessary wire instructions have been provided to the Trustee at
least 15 days prior to the Tax Event Redemption Date) at such place and to such
account as may be designated by each such Holder of Senior Notes, including the
Collateral Agent. If the Trustee holds immediately available funds sufficient to
pay the Redemption Price of the Senior Notes, then, on such Tax Event Redemption
Date, such Senior Notes will cease to be Outstanding.

                  The Trustee shall have no duty or liability to determine or
verify the Redemption Price. Notice of any redemption will be mailed at least 30
days but not more than 60 days before the Tax Event Redemption Date to each
registered Holder of the Senior Notes to be repaid at its registered address.
Unless the Company defaults in payment of the Redemption Price, on and after the
Tax Event Redemption Date interest shall cease to accrue on the Senior Notes,
whether or not such Senior Notes have been received by the Company, and all
other rights of the Holders in respect of the Senior Notes shall terminate and
lapse (other than the right to receive the Redemption Price upon delivery of
such Senior Notes but without interest on such Redemption Price).

                  Section 213. Tax Treatment. The Company agrees, and by
purchasing a beneficial ownership interest in the Senior Notes each Holder, and
any Person that acquires a direct or indirect beneficial interest in the Senior
Notes, will be deemed to have agreed (i) for United States federal income tax
purposes to treat the acquisition of an Upper DECS as the acquisition of a unit
consisting of a forward stock purchase contract and a senior note issued by

                                       18
<PAGE>

the Company and to treat the Senior Notes as indebtedness of the Company that is
subject to Treas. Reg. Sec. 1.1275-4 (the "Contingent Payment Regulations") for
United States federal income tax purposes, (ii) for all tax purposes to treat
the Senior Notes as indebtedness of the Company, (iii) to be bound by the
Company's determination that the Senior Notes are contingent payment debt
instruments subject to the "noncontingent bond method" of accruing original
issue discount within the meaning of the Contingent Payment Regulations with
respect to the Senior Notes, and (iv) to be bound by the Company's projected
payment schedule with respect to the Senior Notes. The provisions of this First
Supplemental Indenture shall be interpreted to further this intention and
agreement of the parties. A Holder of Senior Notes may obtain the amount of
original issue discount, issue date, yield to maturity, comparable yield and
projected payment schedule by submitting a written request to the Company at the
Office or Agency of the Company.

                  Section 214. Events of Default. The Events of Default set
forth in Section 501(1) through (8) of the Base Indenture shall apply to the
Senior Notes.

                                   ARTICLE III

                            MISCELLANEOUS PROVISIONS

                  Section 301. Recitals by Company. The recitals in this First
Supplemental Indenture are made by the Company only and not by the Trustee, and
all of the provisions contained in the Base Indenture in respect of the rights,
privileges, immunities, powers and duties of the Trustee shall be applicable in
respect of the Senior Notes and of this First Supplemental Indenture as fully
and with like effect as if set forth herein in full.

                  Section 302. Ratification and Incorporation of Base Indenture.
As supplemented hereby, the Base Indenture is in all respects ratified and
confirmed, and the Base Indenture and this First Supplemental Indenture shall be
read, taken and construed as one and the same instrument.

                  Section 303. Executed in Counterparts. This First Supplemental
Indenture may be executed in several counterparts, each of which shall be deemed
to be an original, and such counterparts shall together constitute but one and
the same instrument.

                  Section 304. Separability. In case any provisions contained in
this First Supplemental Indenture or in any Senior Note shall be invalid,
illegal or unenforceable, the validity, legality and enforceability of the
remaining provisions shall not in any way be affected or impaired thereby.

                  Section 305. Governing Law. THIS FIRST SUPPLEMENTAL INDENTURE
AND EACH SENIOR NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE
LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE OR INSTRUMENTS
ENTERED INTO AND, IN EACH CASE, PERFORMED IN SAID STATE.

                  Capital One Financial Corporation, a corporation duly
organized and existing under the laws of Delaware (the "Company"), for value
received, hereby promises to pay to [Cede & Co.]* or registered assigns the
principal sum of _______________________ United States Dollars [, or such other
principal amount as shall be set forth in the Schedule of Increases or Decreases
attached hereto,]** at the Company's Office or Agency or Office of the Agent in

of the United States of America as at the time of payment shall be legal tender
for the payment of public and private debts, and to pay interest thereon from
April 23, 2002 or from the next most recent date to which interest has been paid
or duly provided for, quarterly in arrears on each February 17, May 17, August

(i) a successful Remarketing under the Forward Purchase Contract Agreement or
(ii) the relevant Stock Purchase Date, and, thereafter, at the Reset Rate to,
but excluding, the Stated Maturity.

                  The amount of interest payable for any period shall be
computed (i) for any full quarterly period on the basis of a 360-day year of
twelve 30-day months and (ii) for any period shorter than a full quarterly
period, on the basis of a 30-day month and, for periods of less than a month, on
the basis of the actual number of days elapsed per 30-day month. In the event
that any date on which interest is payable on this Security is not a Business
Day, then payment of the interest payable on such date will be made on the next
succeeding day that is a Business Day (and without any interest or payment in
respect of any such delay), in each case with the same force and effect as if
made on the date the payment was originally payable. However, if such Business
Day is in the next calendar year, then such payment will be made on the
preceding Business Day.

                  Payments of the principal of and interest on this Security
shall be made at said Office or Agency of the Company or at the Office of the
Agent in The City of New York to which interest on the Securities has been paid
or duly provided for, until payment of said principal sum has been made or duly
provided for; provided that, unless this Security is a Security issued in global
form ("Global Security"), interest may be paid, at the option of the Company,
(i) by check mailed to the address of the Person entitled thereto as such
address shall appear in the Security Register or (ii) by wire transfer at such
place and to such account at a banking institution in the United States as may
be designated in writing to the Trustee at least sixteen (16) days prior to the
date for payment by the Person entitled thereto. The interest so payable will be
paid to the Person in whose name this Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest; provided that interest payable at the Stated Maturity of
principal will be paid to the Person to whom principal is payable, unless the
Company shall default in the payment of interest due on such interest payment
date after taking into account any applicable grace period, in which case such
defaulted interest shall be paid as set forth in the Indenture. Notwithstanding
the foregoing, as long as this Security is a Global Security, the Company shall
pay or cause to be paid the principal of, and interest on, this Security to the
Holder hereof or a single nominee of the Holder, or, at the option of the
Company, to such other Persons as the Holder hereof may designate, by wire
transfer of immediately available funds on the date such payments are due.

                  The Senior Notes are subject to the covenants set forth in the
Senior Indenture and the First Supplemental Indenture.

                  Reference is made to the further provisions set forth on the
reverse hereof, including the definitions of certain capitalized terms. Such
further provisions shall for all purposes have the same effect as though fully
set forth at this place.

                  This Security shall not be valid or obligatory until the
certificate of authentication hereon shall have been duly signed by the Trustee
acting under the Senior Indenture.

                        Capital One Financial Corporation

                      6.25% Senior Notes Due May 17, 2007

                  This Security is one of a duly authorized issue of debt
securities of the Company, of the series hereinafter specified, all issued or to
be issued under an Indenture, dated as of November 1, 1996, as supplemented by
the First Supplemental Indenture (the "First Supplemental Indenture") dated as
of April 23, 2002 (collectively, as amended or supplemented from time to time,
herein called the "Senior Indenture", which term shall have the meaning assigned
to it in such instrument), and duly executed and delivered by the Company to BNY
Midwest Trust Company, as successor to Harris Trust and Savings Bank, as trustee
(hereinafter, the "Trustee"), to which Senior Indenture reference is hereby made
for a description of the respective rights and duties thereunder of the Trustee,
the Company and the Holders of the Securities. This Security is one of a series
designated as 6.25% Senior Notes Due May 17, 2007 of the Company (hereinafter
called the "Senior Notes"), issued under the Senior Indenture, which is limited
in aggregate principal amount to $747,500,000.

                  Neither the Senior Indenture nor the Senior Notes limit or
otherwise restrict the amount of indebtedness which may be incurred or other
securities which may be issued by the Company. The Senior Notes issued under the
Indenture are direct, unsecured obligations of the Company and will mature on
May 17, 2007. The Senior Notes rank on parity with all other unsecured,
unsubordinated indebtedness of the Company.

                  The Senior Notes will bear interest as set forth on the face
hereof and in the First Supplemental Indenture. The Reset Rate will be the
interest rate per annum that is determined by the Remarketing Agent pursuant to
the Remarketing Agreement as follows: (i) in connection with a successful
Remarketing, the rate of interest that, in the opinion of the Remarketing Agent,
will, when applied to the Outstanding Notes (assuming, even if not true, that
all of the Notes are included in the Remarketing), enable the then current
aggregate market value of the Notes to have a value equal to at least 100.5% of
the Remarketing Value or Accelerated Remarketing Value, as applicable, as of the
Remarketing Date, the Accelerated Remarketing Date or as of any Subsequent
Remarketing Date, as the case may be, or (ii) upon the occurrence of a Failed
Remarketing the rate of interest applicable to the Senior Notes initially until
(A) the Senior Notes are successfully remarketed pursuant to the Forward
Purchase Contract Agreement and the Remarketing Agreement or (B) if the Last
Failed Remarketing or Last Failed Accelerated Remarketing shall have occurred,
the principal of the Senior Notes is paid or made available for payment.
Notwithstanding anything herein to the contrary, the Reset Rate shall in no
event exceed the maximum rate, if any, permitted by applicable law.

                  The Senior Notes are not redeemable prior to maturity except
pursuant to a Tax Event in accordance with the First Supplemental Indenture. If
a Tax Event shall occur and be continuing, the Company may, at its option,
redeem the Senior Notes in whole (but not in part) at any time at a price per
Senior Note equal to the Redemption Price. Installments of interest on the
Senior Notes that are due and payable on or prior to the date of redemption will
be payable to the

                                      A-5
<PAGE>

Holders of the Senior Notes registered as such at the close of business on the
Business Day next preceding such Tax Event Redemption Date. If, following the
settlement of the Forward Purchase Contracts and following the occurrence of a
Tax Event, the Company, at its option, redeems the Senior Notes, the proceeds of
the redemption will be payable in cash to the Holders of the Senior Notes.

                  The Company agrees, and by purchasing a beneficial ownership
interest in the Senior Notes each Holder, and any Person that acquires a direct
or indirect beneficial interest in the Senior Notes, will be deemed to have
agreed (i) for United States federal income tax purposes to treat the
acquisition of an Upper DECS as the acquisition of a unit consisting of a
forward stock purchase contract and a senior note issued by the Company and to
treat the Senior Notes as indebtedness of the Company that is subject to the
Contingent Payment Regulations for United States federal income tax purposes,
(ii) for all tax purposes to treat the Senior Notes as indebtedness of the
Company, (iii) to be bound by the Company's determination that the Senior Notes
are contingent payment debt instruments subject to the "noncontingent bond
method" of accruing original issue discount within the meaning of the Contingent
Payment Regulations with respect to the Senior Notes, and (iv) to be bound by
the Company's projected payment schedule with respect to the Senior Notes. The
provisions of the First Supplemental Indenture shall be interpreted to further
this intention and agreement of the parties. A Holder of Senior Notes may obtain
the amount of original issue discount, issue date, yield to maturity, comparable
yield and projected payment schedule by submitting a written request to the
Company at the Office or Agency of the Company.

                  The Senior Notes are not entitled to any sinking fund.

                  The Senior Notes will be subject to Remarketing and, in the
case of a Failed Remarketing or Failed Accelerated Remarketing, the Senior Notes
will be purchased by the Company unless a Holder makes a contingent election not
to sell its Senior Notes thereto by delivering the notice attached hereto to the
Forward Purchase Contract Agent on or prior to the third Business Day prior to a
Stock Purchase Date, all in accordance with the First Supplemental Indenture and
the Forward Purchase Contract Agreement.

                  In case an Event of Default shall have occurred and be
continuing with respect to the Senior Notes, the principal hereof may be
declared, and upon such declaration shall become, due and payable, in the
manner, with the effect and subject to the conditions provided in the Senior
Indenture. The Senior Indenture provides that in certain circumstances such
declaration and its consequences may be waived by the Holders of a majority in
aggregate principal amount of the Senior Notes then Outstanding. However, any
such consent or waiver by the Holder shall not affect any subsequent default or
impair any right consequent thereon.

                  The Senior Indenture permits the Company and the Trustee,
without the consent of the Holders of the Senior Notes for certain situations
and with the consent of not less than two-thirds of the Holders in aggregate
principal amount of the Outstanding Senior Notes in other situations, to execute
supplemental indentures adding to, modifying or changing various provisions to
the Senior Indenture; provided that no such supplemental indenture, without the
consent of the Holder of each Outstanding Senior Note affected thereby, shall
(i) change the Stated Maturity of the principal of, or any installment of
interest on, the Senior Notes, or reduce

                                      A-6
<PAGE>

the principal amount thereof or the interest thereon, or change the place or
currency of payment of principal of, or interest on, the Senior Notes, or impair
the right to institute suit for the enforcement of any payment on or after the
Stated Maturity thereof, or change the Company's obligation to pay additional
amounts (except as otherwise contemplated in the Senior Indenture); (ii) reduce
the percentage in principal amount of the Outstanding Senior Notes, the consent
of whose Holders is required for any such supplemental indenture, or the consent
of whose Holders is required for any waiver (of compliance with certain
provisions of the Senior Indenture or certain defaults hereunder and their
consequences) provided for in the Senior Indenture; or (iii) modify any of the
provisions of Section 902, 513 or 1008 of the Senior Indenture, except to
increase any such percentage or provide that certain other provisions of the
Senior Indenture cannot be modified or waived without the consent of the Holder
of each Outstanding Senior Note affected thereby.

                  The Company may omit in any particular instance to comply with
any term, provision or condition set forth in Section 1005, 1006 or 1007 of the
Senior Indenture, if before the time for such compliance, the Holders of at
least a majority in principal amount of the Outstanding Senior Notes, by act of
such Holders, either shall waive such compliance in such instance or generally
shall have waived compliance with such term, provision or condition, but no such
waiver shall extend to or affect such term, provision or condition except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the duties of the Trustee in respect of any such
term, provision or condition shall remain in full force and effect.

                  No reference herein to the Senior Indenture and no provision
of this Senior Note or of the Senior Indenture shall alter or impair the
obligations of the Company, which are absolute and unconditional, to pay the
principal of, premium, if any, and interest on this Senior Note at the place, at
the respective times, at the rate and in the coin and currency herein
prescribed.

                  The Senior Notes are issuable in registered form without
coupons in denominations of $50 and integral multiples thereof.

                  At the Office or Agency of the Company or at the Office of the
Agent in The City of New York referred to on the face hereof and in the manner
and subject to the limitations provided in the Indenture, the Senior Notes may
be exchanged for a like aggregate principal amount of Senior Notes of other
authorized denominations.

                  As provided in the Senior Indenture and subject to the
limitations provided therein, the transfer of this Senior Note is registerable
in the Security Register, upon surrender of this Senior Note for registration of
transfer at the Office or Agency of the Company or at the Office of the Agent in
The City of New York in any place where the principal of and interest on this
Senior Note are payable, duly endorsed by, or accompanied by a written
instrument of transfer in form satisfactory to the Company and the Security
Registrar duly executed by, the Holder hereof or his attorney duly authorized in
writing, and thereupon one or more new Senior Notes and of like tenor, of
authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees. No service charge shall be

                                      A-7
<PAGE>

made for any such transfer, but the Company may require payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
relation thereto.

                  Prior to due presentation of this Senior Note for registration
or transfer, the Company, the Trustee, and any authorized agent of the Company
or the Trustee, may deem and treat the Holder hereof as the absolute owner of
the Senior Note (whether or not any payment with respect to this Senior Note
shall be overdue), for the purpose of receiving payment of, or on account of,
the principal hereof and, subject to the provisions on the face hereof, interest
hereon and for all other purposes, and neither the Company nor the Trustee nor
any authorized agent of the Company or the Trustee shall be affected by any
notice to the contrary.

                  No recourse shall be had for the payment of principal of, or
the interest on, this Senior Note, for any claim based hereon, or otherwise in
respect hereof, or based on or in respect of the Indenture or any indenture
supplement thereto, against any incorporator, shareholder, officer or director,
as such, past, present or future, of the Company or of any successor
corporation, either directly or through the Company or any successor
corporation, whether by virtue of any constitution, statute or rule of law or by
the enforcement of any assessment or penalty or otherwise, all such liability
being, by the acceptance hereof and as part of the consideration for the issue
hereof, expressly waived and released.

                  THIS SENIOR NOTE SHALL BE DEEMED TO BE A CONTRACT MADE UNDER
THE LAWS OF THE STATE OF NEW YORK, AND FOR ALL PURPOSES SHALL BE CONSTRUED IN
ACCORDANCE WITH THE LAWS OF SAID STATE.

                  All terms used in this Senior Note (and not otherwise defined
in this Senior Note) that are defined in the Indenture, the Forward Purchase
Contract Agreement, the Remarketing Agreement or the Pledge Agreement, as the
case may be, shall have the meanings assigned to them in the Indenture, the
Forward Purchase Contract Agreement, the Remarketing Agreement or the Pledge
Agreement, as the case may be and as the context may require.

     THIRD SUPPLEMENTAL INDENTURE, dated as of April 22, 2002, between

     WHEREAS, pursuant to the Indenture dated as of June 11, 2001 (as amended,
the "Indenture"), between COR Therapeutics, Inc. ("COR") and the Trustee, COR
issued $300,000,000 aggregate principal amount of 4.50% Convertible Senior Notes
due June 15, 2006 (the "Securities");

     WHEREAS, COR, the Company and the Trustee have entered into a First
Supplemental Indenture, dated as of February 12, 2002 (the "First Supplemental
Indenture"), to the Indenture, which supplemental indenture provides (i) that
the Securities shall be convertible into shares of the Company's Common Stock,
(ii) for adjustments of the Conversion Rate which shall be as nearly equivalent
as may be practicable to the adjustments provided for in Article 11 of the
Indenture, and (iii) for a full and unconditional guarantee of the obligations
of COR under the Indenture and the Securities by the Company on the terms and
conditions set forth therein;

     WHEREAS, the Company and the Trustee have entered into a Second
Supplemental Indenture, dated as of February 12, 2002 (the "Second Supplemental
Indenture"), to the Indenture, which supplemental indenture provides that (i)

     WHEREAS, Section 8.1 of the Indenture provides that the Company and the

covenants of the Company for the benefit of the Holders of Securities; and

     WHEREAS, the Company has complied with all conditions precedent provided
for in the Indenture relating to this Third Supplemental Indenture.

         NOW, THEREFORE, in consideration of the foregoing premises, it is
mutually covenanted and agreed, for the equal and proportionate benefit of all
Holders of Securities, as follows:

                                  ARTICLE ONE

                                  DEFINITIONS

SECTION 1.1. Capitalized terms used but not defined herein shall have the
meanings ascribed to such terms in the Indenture.

<PAGE>

SECTION 1.2.  Section 1.1 of the Indenture is hereby amended to add the
following definitions:

     "Company Notice of Put Right" has the meaning specified in Section 2.2 of
the Third Supplemental Indenture.

     "Put Right Date" has the meaning specified in Section 2.1 of the Third
Supplemental Indenture.

     "Put Right Notice" has the meaning specified in Section 2.2 of the Third
Supplemental Indenture.

     "Put Right Price" has the meaning specified in Section 2.1 of the Third
Supplemental Indenture.

                                  ARTICLE TWO

                REPURCHASE OF SECURITIES AT OPTION OF THE HOLDER

SECTION 2.1. Right to Require Repurchase. Each Holder shall have the right, at
the Holder's option, to require the Company to repurchase and upon the exercise
of such right the Company shall repurchase, all of such Holder's Securities, or
any portion of the principal amount thereof that is equal to U.S.$1,000 or any
greater integral multiple of U.S.$1,000, on April 29, 2003 (the "Put Right
Date") at a purchase price equal to 109.50% of the principal amount of the
Securities to be repurchased (the "Put Right Price"). Whenever in the Indenture
(including Sections 2.2, 3.1, 5.1(1) and 5.8 thereof) there is a reference to
the principal of any Security as of any time, such reference shall be deemed to
include reference to the Put Right Price payable in respect of such Security to
the extent that such Put Right Price is, was or would be so payable at such
time; provided, however, that the foregoing shall not apply to any reference to
the principal of any Security that concerns the determination of the amount of
interest due or owing under such Security. If any of the foregoing provisions or
other provisions of this Article Two are inconsistent with applicable law,
including without limitation Rule 13e-4 or Regulation 14E promulgated under the
Exchange Act, such law shall govern.

SECTION 2.2.  Notices; Method of Exercising Repurchase Right, Etc.

     (1) On or before the Business Day that is 21 Business Days prior to the Put
Right Date, the Company or, at the request and expense of the Company on or
before the Business Day that is 21 Business Days prior to the Put Right Date,
the Trustee, shall give to all Holders of Securities, in the manner provided in
Section 1.6 of the Indenture, notice (the "Company Notice of Put Right") of the
repurchase right set forth herein. The Company shall also deliver a copy of the
Company Notice of Put Right to the Trustee. The Company Notice of Put Right
shall state:

          (a) the Put Right Date,

          (b) the Put Right Price,

                                      -2-

<PAGE>

          (c) a description of the procedure which a Holder must follow to
exercise the repurchase right, and the place or places where such Securities,
are to be surrendered for payment of the Put Right Price and accrued interest,
if any,

          (d) that on the Put Right Date the Put Right Price, and accrued
interest, if any, will become due and payable upon each such Security designated
by the Holder to be repurchased, and that interest thereon shall cease to accrue
on and after said date,

          (e) the Conversion Rate then in effect, the date on which the right to
convert the principal amount of the Securities to be repurchased will terminate
and the place or places where such Securities may be surrendered for conversion,

          (f) the place or places that the Put Right Notice (as defined below)
shall be delivered, and the form of such Notice, and

          (g) the CUSIP number or numbers of such Securities.

No failure of the Company to give the foregoing notices or defect therein shall
limit any Holder's right to exercise a repurchase right or affect the validity
of the proceedings for the repurchase of Securities pursuant to this Article
Two.

     (2) To exercise a repurchase right, a Holder shall deliver to the Trustee
at any time until 9:00 a.m., New York time, on the Put Right Date, (i) written
notice of the Holder's exercise of such right, which notice shall set forth the
name of the Holder, the principal amount of the Securities to be repurchased
(and, if any Security is to repurchased in part, the serial number thereof, the
portion of the principal amount thereof to be repurchased and the name of the
Person in which the portion thereof to remain Outstanding after such repurchase
is to be registered) and a statement that an election to exercise the repurchase
right is being made thereby (a "Put Right Notice"), and (ii) the Securities with
respect to which the repurchase right is being exercised. Notwithstanding the
delivery of a Put Right Notice by a Holder, such Holder's Securities shall
remain convertible into the Company's Common Stock until the principal of such
Securities (or portion thereof, as the case may be) shall have been paid or duly
provided for. Notwithstanding anything herein to the contrary, any Holder
delivering to the Trustee a Put Right Notice shall have the right to withdraw
such notice at any time prior to 9:00 a.m., New York time, on the Put Right Date
by delivery of a written notice of withdrawal to the Trustee in accordance with
Section 2.4. The Trustee shall promptly notify the Company of its receipt of any
Put Right Notice or written notice of withdrawal thereof.

SECTION 2.3. Payment of Put Right Price. In the event a repurchase right shall
be exercised in accordance with the terms hereof, the Company shall pay or cause
to be paid to the Trustee the Put Right Price in cash for payment to the Holder
on the Put Right Date, together with accrued and unpaid interest to the Put
Right Date payable with respect to the Securities as to which the repurchase
right has been exercised; provided, however, that installments of interest that
mature on or prior to the Put Right Date shall be payable in cash to the Holders
of such Securities, or one or more Predecessor Securities, registered as such at
the close of business on the relevant Regular Record Date.

                                      -3-

<PAGE>

     If any Security (or portion thereof) surrendered for repurchase shall not
be so paid on the Put Right Date, the principal amount of such Security (or
portion thereof, as the case may be) shall, until paid, bear interest to the
extent permitted by applicable law from the Put Right Date at the rate of 4.50%
per annum, and each Security shall remain convertible into the Company's Common
Stock until the principal of such Security (or portion thereof, as the case may
be) shall have been paid or duly provided for.

     Any Security which is to be repurchased only in part shall be surrendered
to the Trustee (with, if the Company or the Trustee so requires, due endorsement
by, or a written instrument of transfer in form satisfactory to the Company and
the Trustee duly executed by, the Holder thereof or his attorney duly authorized
in writing), and the Company shall execute, and the Trustee shall authenticate
and make available for delivery to the Holder of such Security without service
charge, a new Security or Securities, containing identical terms and conditions,
each in an authorized denomination in aggregate principal amount equal to and in
exchange for the unrepurchased portion of the principal of the Security so
surrendered.

     All Securities delivered for repurchase shall be delivered to the Trustee
to be canceled at the direction of the Trustee, which shall dispose of the same
as provided in Section 3.9 of the Indenture.

SECTION 2.4.  Withdrawal of Put Right Notice. A Put Right Notice may be
withdrawn by means of a written notice of withdrawal delivered to the Trustee at
any time prior to 9:00 a.m., New York time, on the Put Right Date specifying:

     (1) the certificate number of the Securities in respect of which such
notice of withdrawal is being submitted;

     (2) the portion of the principal amount thereof of the Securities with
respect to which such notice of withdrawal is being submitted; and

     (3) the portion of the principal amount thereof, if any, of such Securities
which remains subject to the original Put Right Notice and which has been or
will be delivered for purchase by the Company.
