per annum, until the principal hereof is paid or made available for payment,
provided that any principal, and any such installment of interest, that is
overdue shall bear interest at the rate of __% per annum (to the extent that the
payment of such interest shall be legally enforceable), from the dates such
amounts are due until they are paid or made available for payment, and such
interest shall be payable on demand. The interest so payable, and punctually
paid or duly provided for, on any Interest Payment Date will, as provided in
such Indenture, be paid to the Person in whose name this Series __ Senior Note
(or one or more Predecessor Securities) is registered at the close of business
on the Regular Record Date for such interest, which shall be the close of
business on the Business Day preceding such Interest Payment Date; provided,
that with respect to Series __ Senior Notes that are not represented by one or
more Global Securities, the Regular Record Date shall be the close of business
on the 15/th/ calendar day (whether or not a Business Day) preceding such
Interest Payment Date. Any such interest not so punctually paid or duly provided
for will forthwith cease to be payable to the Holder on such Regular Record Date
and may either be paid to the Person in whose name this Series __ Senior Note
(or one or more Predecessor Securities) is registered at the close of business
on a Special Record Date for the payment of such Defaulted Interest to be fixed
by the Trustee, notice whereof shall be given to Holders of Series __ Senior
Notes not less than 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 on which the Series __ Senior Notes may be listed, and upon
such notice as may be required by such exchange, all as more fully provided in
said Indenture.

     Payments of interest on the Series __ Senior Notes will include interest
accrued to but excluding the respective Interest Payment Dates. Interest
payments for the Series __ Senior Notes shall be computed and paid on the basis
of a 360-day year of twelve 30-day months. In the event that any date on which
interest is payable on the Series __ Senior Notes 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.

     Payment of the principal of and interest on this Series __ Senior Note will
be made at the office of the Paying Agent, in the Borough of Manhattan, City and
State 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 at the Stated Maturity of any Series __ Senior
Note being made upon surrender of such Series __ Senior Note to such office or
agency; provided, however, that at the option of the Company payment of
interest, subject to such surrender where applicable, may be made (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.

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

Trustee referred to on the reverse hereof by manual signature, this Series __

                      [REVERSE OF SERIES ___ SENIOR NOTE]

     This Security is one of a duly authorized issue of securities of the
Company (herein called the "Securities"), issued and to be issued in one or more
series under an Indenture, dated as of June 1, 2000, as heretofore supplemented
and amended and as further supplemented by a _____________ Supplemental
Indenture dated as of ____________, 20__ (collectively, as amended or
supplemented from time to time, herein called the "Indenture", which term shall
have the meaning assigned to it in such instrument), between the Company and The
Chase Manhattan Bank, as Trustee (herein called the "Trustee", which term
includes any successor trustee under the Indenture), and reference is hereby
made to the Indenture for a statement of the respective rights, limitations of
rights, duties and immunities thereunder of the Company, the Trustee and the
Holders of the Securities and of the terms upon which the Securities are, and
are to be, authenticated and delivered.  This Security is one of the series
designated on the face hereof (the "Series __ Senior Notes") which is unlimited
in aggregate principal amount.

     The Series __ Notes are redeemable, in whole or in part, [FIRST ALTERNATIVE
- at any time] [SECOND ALTERNATIVE - OPTIONAL REDEMPTION - at any time on or
after __________, 20__,] in the manner and with the effect provided in the
Indenture.

     If an Event of Default with respect to Series __ Senior Notes shall occur
and be continuing, the principal of the Series __ Senior Notes may be declared
due and payable in the manner and with the effect provided in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected.  The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive certain past defaults under
the Indenture and their consequences.  Any such consent or waiver by the Holder
of this Series __ Senior Note shall be conclusive and binding upon such Holder
and upon all future Holders of this

                                       3
<PAGE>

Series __ Senior Note and of any Series __ Senior Note issued upon the
registration of transfer hereof or in exchange therefor or in lieu hereof,
whether or not notation of such consent or waiver is made upon this Series __
Senior Note.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Series __ Senior Note shall not have the right to institute any
proceeding with respect to the Indenture or for the appointment of a receiver or
trustee or for any other remedy thereunder, unless such Holder shall have
previously given the Trustee written notice of a continuing Event of Default
with respect to the Series __ Senior Notes, the Holders of not less than a
majority in principal amount of the Series __ Senior Notes at the time
Outstanding shall have made written request to the Trustee to institute
proceedings in respect of such Event of Default as Trustee and offered the
Trustee reasonable indemnity, and the Trustee shall not have received from the
Holders of a majority in principal amount of Series __ Senior Notes at the time
Outstanding a direction inconsistent with such request, and shall have failed to
institute any such proceeding for 60 days after receipt of such notice, request
and offer of indemnity.  The foregoing shall not apply to any suit instituted by
the Holder of this Series __ Senior Note for the enforcement of any payment of
principal hereof or premium, if any, or interest hereon on or after the
respective due dates expressed or provided for herein.

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

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Series __ Senior Note is registrable in the Security
Register, upon surrender of this Series __ Senior Note for registration of
transfer at the office or agency of the Company in any place where the principal
of, premium, if any, and interest on this Series __ 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 Series __ 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.

     The Series __ Senior Notes are issuable only in registered form without
coupons in denominations of $__________ and any integral multiple thereof.  As
provided in the Indenture and subject to certain limitations therein set forth,
Series __ Senior Notes are exchangeable for a like aggregate principal amount of
Series __ Senior Notes having the same Stated Maturity and of like tenor of any
authorized denominations as requested by the Holder upon surrender of the Series
__ Senior Note or Series __ Senior Notes to be exchanged at the office or agency
of the Company.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this Series __ Senior Note for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name this Security is registered as the owner
hereof for all purposes, whether or not this Series __

     2.3  Form and Payment; Minimum Transfer Restriction.

          (a) The Junior Subordinated Debentures shall be issued to the

the registered holder at such address as shall appear in the Register.
[Notwithstanding the foregoing, so long as the registered holder of any Junior
Subordinated Debentures is the Property Trustee, the payment of the principal of
and interest (including Additional Interest and Additional Tax Sums, if any) on
such Junior Subordinated Debentures held by the Property Trustee will be made at

<PAGE>

     2.4  Exchange and Registration of Transfer of Junior Subordinated
Debentures; Restrictions on Transfers; Depositary. [If distributed to holders of
Capital Securities pursuant to Section 8.2 of the Trust Agreement, the Junior
Subordinated Debentures will be issued to such holders in the same form as the
Capital Securities that such Junior Subordinated Debentures replace in
accordance with the following procedures:]

          (a) So long as Junior Subordinated Debentures are eligible for book-
entry settlement with the Depositary, or unless required by law, all Junior
Subordinated Debentures that are so eligible will be represented by one or more
Junior Subordinated Debentures in global form (a "Global Debenture") registered
in the name of the Depositary or the nominee of the Depositary.  Except as
provided in Section 2.4(c) below, beneficial owners of a Global Debenture shall
not be entitled to have Definitive Debenture Certificates registered in their
names, will not receive or be entitled to receive physical delivery of
Definitive Debenture Certificates and will not be registered holders of such
Global Debentures.

          (b) The transfer and exchange of beneficial interests in Global
Debentures shall be effected through the Depositary in accordance with the
Indenture and the procedures and standing instructions of the Depositary and the
Trustee shall make appropriate endorsements to reflect increases or decreases in
principal amounts of such Global Debentures.

          (c) Notwithstanding any other provisions of the Indenture (other than
the provisions set forth in this Section 2.4(c)), a Global Debenture may not be
exchanged in whole or in part for Junior Subordinated Debentures registered, and
no transfer of a Global Debenture may be registered, in the name of any person
other than the Depositary or a nominee thereof unless (i) such Depositary (A)
has notified the Company that it is unwilling or unable to continue as
Depositary for such Global Debenture or (B) has ceased to be a clearing agency
registered as such under the Exchange Act and no successor Depositary has been
appointed by the Company within 90 days after its receipt of such notice or its
becoming aware of such ineligibility, (ii) there shall have occurred and be
continuing an Event of Default, or any event which after notice or lapse of time
or both would be an Event of Default under the Indenture, with respect to such
Debenture, or (iii) the Company, in its sole discretion, instructs the Trustee
to exchange such Global Debenture for a Junior Subordinated Debenture that is
not a Global Debenture (in which case such exchange shall be effected by the
Trustee).

          The Depositary shall be a clearing agency registered under the
Exchange Act.  The Company initially appoints The Depository Trust Company to
act as Depositary with respect to the Global Debentures.  Initially, any Global
Debentures shall be registered in the name of Cede & Co., as the nominee of the
Depositary, and deposited with the Trustee as custodian for Cede & Co.

          Definitive Junior Subordinated Debentures issued in exchange for all
or a part of a Global Debenture pursuant to this Section 2.4(c) shall be
registered in such names and in such authorized denominations as the Depositary,
pursuant to instructions from its direct or indirect participants or otherwise,
shall instruct the Trustee.  Upon execution and authentication, the Trustee
shall deliver such definitive Junior Subordinated Debentures to the person in
whose names such definitive Junior Subordinated Debentures are so registered.

                                       7
<PAGE>

          So long as Junior Subordinated Debentures are represented by one or
more Global Debentures, (i) the registrar for the Junior Subordinated Debentures
and the Trustee shall be entitled to deal with the clearing agency for all
purposes of the Indenture relating to such Global Debentures as the sole holder
of the Junior Subordinated Debentures evidenced by such Global Debentures and
shall have no obligations to the holders of beneficial interests in such Global
Debentures; and (ii) the rights of the holders of beneficial interests in such
Global Debentures shall be exercised only through the clearing agency and shall
be limited to those established by law and agreements between such holders and
the clearing agency and/or the participants in the clearing agency.

          At such time as all interests in a Global Debenture have been paid,
redeemed, exchanged, repurchased or canceled, such Global Debenture shall be,
upon receipt thereof, canceled by the Trustee in accordance with standing
procedures and instructions of the Depositary. At any time prior to such
cancellation, if any interest in a Global Debenture is exchanged for definitive
Junior Subordinated Debentures, redeemed by the Company pursuant to Article 3 or
canceled, or transferred for part of a Global Debenture, the principal amount of
such Global Debenture shall, in accordance with the standing procedures and
instructions of the Depositary be reduced or increased, as the case may be, and
an endorsement shall be made on such Global Debenture by, or at the direction
of, the Trustee to reflect such reduction or increase.

     2.5  Interest.

          (a) Each Junior Subordinated Debenture will bear interest at the rate
of ___% per annum (the "Coupon Rate") from ___________, 20__ until the principal
thereof becomes due and payable, and will bear interest on any overdue principal
at the Coupon Rate and (to the extent that payment of such interest is
enforceable under applicable law) on any overdue installment of interest at the
Coupon Rate ("Additional Interest"), compounded semi-annually, payable (subject
to the provisions of Article 4) semi-annually in arrears on the 15th day of
January and July of each year (each, an "Interest Payment Date"), commencing on
______ 15, 20__ to the Person in whose name such Junior Subordinated Debenture
is registered, subject to certain exceptions, at the close of business on the
Record Date next preceding such Interest Payment Date.  The "Record Date" for
payment of interest will be the Business Day next preceding the Interest Payment
Date, unless such Junior Subordinated Debenture is registered to a holder other
than the Property Trustee or a nominee of the Depositary, in which case the
Record Date for payment of interest will be the fifteenth calendar day preceding
the applicable Interest Payment Date, whether or not a Business Day. [Until
liquidation, if any, of the Trust, each Junior Subordinated Debenture will be
held in the name of the Property Trustee in trust for the benefit of the holders
of the Trust Securities.]

          (b) The amount of interest payable for any period will be computed on
the basis of a 360-day year of twelve 30-day months.  In the event that any date
on which interest is payable on the Junior Subordinated Debentures is not a
Business Day, then payment of interest payable on such date will be made on the
next succeeding day which is a Business Day (and without any interest or other
payment in respect of any such delay), except that, if such Business Day is in
the next succeeding calendar year, such payment shall be made on the next
preceding day which is a Business Day, in each case with the same force and
effect as if made on the date such payment was originally payable.

                                       8
<PAGE>

          (c) [The Company will also pay any Additional Tax Sums as additional
distributions on the Junior Subordinated Debentures if the Trust is required to
pay any additional taxes, duties or other governmental charges as a result of a
Tax Event.]

     2.6  [Direct Action.  In addition to any right of Direct Action granted
under Section 6.5 of the Trust Agreement to the holders of Capital Securities,
if the Property Trustee fails to enforce its rights under the Trust Agreement or
the Indenture to the fullest extent permitted by law and subject to the terms of
the Trust Agreement and the Indenture, then a holder of Capital Securities may
directly institute a proceeding against the Company to enforce the Property
Trustee's rights under the Trust Agreement or the Indenture without first
instituting a legal proceeding against the Property Trustee or any other
person.]

                                  ARTICLE IV
                     EXTENSION OF INTEREST PAYMENT PERIOD

     4.1  Extension of Interest Payment Period. So long as no Event of Default
under Section 6.1 of the Base Indenture has occurred and is continuing, the
Company shall have the right, subject to the provisions of Section 2.10 of the
Base Indenture, at any time during the term of the Junior Subordinated
Debentures, from time to time to defer the payment of interest by extending the
interest payment period of such Junior Subordinated Debentures for a period not
exceeding 10 consecutive semi-annual periods (an "Extension Period"), during
which Extension Period the Company shall not have the right to make partial
payments of interest. No Extension Period shall end on a date other than an
Interest Payment Date or extend beyond the Stated Maturity of the Junior
Subordinated Debentures. To the extent permitted by applicable law, interest,
the payment of which has been deferred because of an Extension Period imposed
pursuant to this Section 4.1, will bear Additional Interest compounded semi-
annually. At the end of the Extension Period, the Company shall pay all interest
then accrued and unpaid on the Junior Subordinated Debentures, including any
Additional Interest and Additional Tax Sums, if applicable, to the holders of
the Junior Subordinated Debentures in whose names the Junior Subordinated
Debentures are registered in the Register on the first Record Date preceding the
end of the Extension Period. Before the termination of any Extension Period, the
Company may further extend such Extension Period, provided that such period
together with all such further extensions thereof shall not exceed 10
consecutive semi-annual periods, or extend beyond the Stated Maturity. At any
time following the termination of any Extension Period and upon the payment of
any accrued and unpaid Additional Interest and Additional Tax Sums, if
applicable, then due, the Company may elect to begin a new Extension Period,
subject to the foregoing requirements. No interest shall be due and payable
during an Extension Period, except at the end thereof.

          During any such Extension Period, the Company shall not (i) declare or
pay any dividends or distributions on, or redeem, purchase, acquire or make a
liquidation payment with respect to, any of the Company's Capital Stock or (ii)
make any payment of principal of or interest on or repay, repurchase or redeem
any debt securities of the Company that rank on a parity with or junior to this
Debenture or make any guarantee payments with respect to any [DRI Guarantee or
other] guarantee by the Company of the debt securities of any Subsidiary of the
Company that by its terms ranks on a parity with or junior to this Debenture
(other than (a) dividends or distributions in Common Stock, (b) any declaration
of a dividend in connection with the implementation of a Rights Plan, the
issuance of any Capital Stock or any class or series of preferred stock of the
Company under any Rights Plan or the redemption or repurchase of any rights
distributed pursuant to a Rights Plan, [(c) payments under any DRI Guarantee
relating to the Capital Securities issued by the DRI Trust holding the Junior
Subordinated Debentures,] and (d) purchases of Common Stock related to the
issuance of Common Stock or rights under any of the Company's benefit plans for
its directors, officers, employees, consultants or advisors).

     The interest so payable will, subject to certain exceptions provided in the
Indenture hereinafter referred to, be paid to the person in whose name this
Debenture is registered at the close of business on the Record Date next

next preceding the Interest Payment Date, unless this Debenture is registered to
a holder other than [the Property Trustee or] a nominee of The Depository Trust
Company, in which case the Record Date will be the fifteenth calendar day

Extension Period, the Company shall pay all interest then accrued and unpaid on
this Debenture, including any Additional Interest and Additional Tax Sums, if
applicable, to the Person in whose name this Debenture is registered in the

Extension Period and upon the payment of any accrued and unpaid Additional
Interest and Additional Tax Sums, if applicable, then due, the Company may elect

     [As provided in and subject to the provisions in the Indenture, the Company
shall have the option to redeem the Debentures of this series [FIRST ALTERNATIVE
- OPTIONAL REDEMPTION - at any time, in whole but not in part,] [SECOND
ALTERNATIVE - OPTIONAL REDEMPTION - at any time on or after _________, 20__, in
whole or in part,] at the Optional Redemption Price. In addition, if a Special
Event shall occur and be continuing, the Company may redeem the Debentures of
this series at any time within 90 days after the occurrence of that Special
Event, in whole but not in part, at the Special Event Redemption Price.]

     In the case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Debentures of this
series 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
Indenture.

     Any consent or waiver by the Holder of this Debenture given as provided in
the Indenture (unless effectively revoked as provided in the Indenture) shall be
conclusive and binding upon such Holder and upon all future Holders of this
Debenture and of any Debenture issued in exchange, registration of transfer, or
otherwise in lieu hereof irrespective of whether any notation of such consent or
waiver is made upon this Debenture or such other Debentures. No reference herein
to the Indenture and no provision of this Debenture or of the Indenture shall
alter or impair the obligation of the Company, which is absolute and
unconditional, to pay the principal of and interest on this Debenture, at the
places, at the respective times, at the rate and in the coin or currency herein
prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Debenture may be registered on the Register of the
Debentures of this series upon surrender of this Debenture for registration of
transfer at the offices maintained by the Company or its agent for such purpose,
duly endorsed by the Holder hereof or his attorney duly authorized in writing,
or accompanied by a written instrument of transfer in form satisfactory to the
Company and the Securities registrar duly executed by the Holder hereof or his
attorney duly authorized in writing, but without payment of any charge other
than a sum sufficient to reimburse the Company for any tax or other governmental
charge incident thereto.  Upon any such registration of transfer, a new
Debenture or Debentures of authorized denomination or denominations for the same
aggregate principal amount will be issued to the transferee in exchange herefor.

     Prior to due presentment for registration of transfer of this Debenture,
the Company, the Trustee, and any agent of the Company or the Trustee may deem
and treat the person in whose name this Debenture shall be registered upon the
Register of the Debentures of this series as the absolute owner of this
Debenture (whether or not this Debenture shall be overdue and notwithstanding
any notation of ownership or other writing hereon) for the purpose of receiving
payment of or on account of the principal hereof and, subject to the provisions
on the face hereof, interest due hereon and for all other purposes; and neither
the Company nor the Trustee nor any such agent shall be affected by any notice
to the contrary.

     No recourse shall be had for the payment of the principal of or interest on

based on or in respect of the Indenture or any indenture supplemental thereto,
against any stockholder, officer, director or employee, as such, past, present
or future, of the Company or of any successor corporation, either directly or
through the Company, 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 a part of the consideration for
the issue hereof, expressly waived and released.
