                          LINCOLN NATIONAL CORPORATION

            7.65% Junior Subordinated Deferrable Interest Debentures,
                                    Series E
No. E-1 $177,836,000

     LINCOLN NATIONAL CORPORATION, a corporation organized and existing under
the laws of Indiana (hereinafter called the "Company", which term includes any
successor corporation under the Indenture hereinafter referred to), for value
received, hereby promises to pay to Bank One Trust Company, National
Association, as Property Trustee of Lincoln National Capital V, or registered
assigns, the principal sum of one hundred seventy seven million eight hundred
thirty six thousand dollars ($177,836,000) on November 1, 2050. The Company
further promises to pay interest on said principal sum from November 19, 2001 or
from the most recent interest payment date (each such date, an "Interest Payment
Date") on which interest has been paid or duly provided for, quarterly (subject
to deferral as set forth herein) in arrears on the last day of March, June,
September and December of each year, commencing December 31, 2001, at the rate
of 7.65% per annum, until the principal hereof shall have become due and
payable, plus Additional Interest, if any, until the principal hereof is paid or
duly provided for or made available for payment and on any overdue principal and
(without duplication and to the extent that payment of such interest is
enforceable under applicable law) on any overdue installment of interest at the
rate of 7.65% per annum, compounded quarterly. The amount of interest payable
for any period will be computed on the basis of twelve 30-day months and a
360-day year. The amount of interest payable for any partial period shall be
computed on the basis of the number of days elapsed in a 360-day year of twelve
30-day months. In the event that any date on which interest is payable on this
Security is not a Business Day, then a payment of the 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 immediately preceding Business Day, in each case with the
same force and effect as if made on the date the payment was originally payable.
A "Business Day" shall mean any day other than (i) a Saturday or Sunday, (ii) a
day on which banking institutions in The City of New York are authorized or
required by law or executive order to remain closed or (iii) a day on which the
Corporate Trust Office of the Trustee or the principal office of the Property
Trustee under the Trust Agreement hereinafter referred to for Lincoln National
Capital V is closed for business. The interest installment so payable, and
punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Indenture, be paid to the Person in whose name this Security (or
one or more Predecessor Securities, as defined in the Indenture) is registered
at the close of business on the Regular Record Date for such interest
installment, which shall be the date which is fifteen days next preceding such
Interest Payment Date. Any such interest installment not so punctually paid or
duly provided for shall 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
Security (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 Securities
of this series 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

<PAGE>

securities exchange on which the Securities of this series may be listed, and
upon such notice as may be required by such exchange, all as more fully provided
in said Indenture.

     The Company shall have the right at any time during the term of this
Security, from time to time, to defer the payment of interest on such Security
for up to 20 consecutive quarterly interest payment periods with respect to each
deferral period (each an "Extension Period"), during which Extension Periods the
Company shall have the right to make partial payments of interest on any
Interest Payment Date, and at the end of which the Company shall pay all
interest then accrued and unpaid (together with Additional Interest thereon to
the extent permitted by applicable law); provided that during any such Extension
Period, the Company will not, and will not permit any Subsidiary of the Company
to, (i) declare or pay any dividends or distributions or redeem, purchase,
acquire or make a liquidation payment with respect to any of the Company's
outstanding capital stock or (ii) make any payment of principal of, interest or
premium, if any, on or repay, repurchase or redeem any debt security of the
Company that ranks pari passu with or junior in interest to this Security or
make any guarantee payments with respect to any guarantee by the Company of the
debt securities of any subsidiary of the Company if such guarantee ranks pari
passu with or junior in interest to the Securities (other than (a) dividends or
distributions in Common Stock of the Company, (b) redemptions or purchases of
any rights pursuant to the Company's Rights Plan, or any successor to such
Rights Plan, and the declaration of a dividend of such rights or the issuance of
Stock under such plans in the future, (c) payments under any Lincoln Guarantee
(as defined in the Indenture), and (d) purchases of Common Stock related to the
issuance of Common Stock under any of the Company's benefit plans for its
directors, officers or employees). Prior to the termination of any such
Extension Period, the Company may further extend the interest payment period,
provided that no Extension Period shall exceed 20 consecutive quarters or extend
beyond the Maturity of this Security. Upon the termination of any such Extension
Period and upon the payment of all accrued and unpaid interest and any
Additional Interest then due, the Company may elect to begin a new Extension
Period, subject to the above requirements. No interest shall be due and payable
during an Extension Period except at the end thereof. The Company shall give the
Holder of this Security and the Trustee notice of its election to begin an
Extension Period at least one Business Day prior to the earlier of (i) the date
the Distributions on the Preferred Securities are payable or (ii) the date the
Administrative Trustees are required to give notice to any securities exchange
or other applicable self-regulatory organization or to holders of such Preferred
Securities of the record date or the date such Distributions are payable, but in
any event not less than one Business Day prior to such record date.

     Payment of the principal of (and premium, if any) and interest on this
Security will be made at the office or agency of the Company maintained for that
purpose in the United States, 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; provided, however, that at the option of the Company payment of
interest may be made (i) by check mailed to the address of the Person entitled
thereto as such address shall appear in the Securities Register or (ii) by wire
transfer in immediately available funds at such place and to such account as may
be designated by the Person entitled thereto as specified in the Securities
Register.

     The indebtedness evidenced by this Security is, to the extent provided in
the Indenture, subordinate and subject in right of payments to the prior payment
in full of all Senior Debt, and this Security is issued subject to the
provisions of the Indenture with respect thereto.

<PAGE>

Each Holder of this Security, by accepting the same, (a) agrees to and shall be
bound by such provisions, (b) authorizes and directs the Trustee on his behalf
to take such actions as may be necessary or appropriate to effectuate the
subordination so provided and (c) appoints the Trustee his attorney-in-fact for
any and all such purposes. Each Holder hereof, by his acceptance hereof, waives
all notice of the acceptance of the subordination provisions contained herein
and in the Indenture by each holder of Senior Debt, whether now outstanding or
hereafter incurred, and waives reliance by each such holder upon said
provisions.

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

     Unless the certificate of authentication hereon has been executed by the
Trustee referred to on the reverse hereof by manual signature, this Security
shall not be entitled to any benefit under the Indenture or be valid or
obligatory for any purpose.

<PAGE>

     IN WITNESS WHEREOF, the Company has caused this instrument to be duly
executed under its corporate seal.

                              [REVERSE OF SECURITY]

     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 a Junior Subordinated Indenture, dated as of May 1, 1996 (herein
called the "Indenture"), between the Company and Bank One Trust Company,
National Association (as successor in interest to The First National Bank of
Chicago), as Trustee (herein called the "Trustee," which term includes any
successor trustee under the Indenture), to which Indenture and all indentures
supplemental thereto reference is hereby made for a statement of the respective
rights, limitations of rights, duties and immunities thereunder of the Trustee,
the Company 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, limited in aggregate principal
amount to $177,836,000.

     All terms used in this Security that are defined in the Indenture or in the
Amended and Restated Trust Agreement, dated as of November 19, 2001 (the "Trust
Agreement"), for Lincoln National Capital V among Lincoln National Corporation,
as Depositor, and the Trustees named therein, shall have the meanings assigned
to them in the Indenture or the Trust Agreement, as the case may be.

     On or after November 19, 2006, the Company may at any time, at its option,
subject to the terms and conditions of Article Eleven of the Indenture, redeem
this Security in whole at any time or in part from time to time, without premium
or penalty, at a redemption price equal to 100% of the principal amount thereof
plus the accrued and unpaid interest, including Additional Interest, if any, to
the date fixed for redemption.

     If a Special Event in respect of Lincoln National Capital V shall occur and
be continuing, the Company may, at its option, redeem this Security within 90
days of the occurrence of such Special Event, in whole but not in part, subject
to the provisions of Section 11.7 and the other provisions of Article Eleven of
the Indenture. The redemption price for any Security so redeemed shall be equal
to 100% of the principal amount thereof plus accrued and unpaid interest,
including Additional Interest, if any, to the date fixed for redemption.

     In the event of redemption of this Security in part only, a new Security or
Securities of this series for the unredeemed portion hereof will be issued in
the name of the Holder hereof upon the cancellation hereof.

     If an Event of Default with respect to Securities of this series shall
occur and be continuing, the principal of the Securities of this series may be
declared due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture.

     The Indenture contains provisions for satisfaction, discharge and
defeasance at any time of the entire indebtedness of this Security upon
compliance by the Company with certain conditions set forth in the Indenture.

     The Indenture permits, with certain exceptions as therein provided, the
Company and the Trustee at any time to enter into a supplemental indenture or
indentures for the purpose

<PAGE>

of modifying in any manner the rights and obligations of the Company and of the
Holders of the Securities, with the consent of the Holders of not less than a
majority in principal amount of the Outstanding Securities of each series to be
affected by such supplemental indenture. The Indenture also contains provisions
permitting 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 compliance by the Company with certain
provisions of the Indenture and certain past defaults under the Indenture and
their consequences. Any such consent or waiver by the Holder of this Security
shall be conclusive and binding upon such Holder and upon all future Holders of
this Security and of any Security issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, if an Event
of Default with respect to Securities of this series at the time Outstanding
occurs and is continuing, then and in every such case the Trustee or the Holders
of not less than 25% in principal amount of the Outstanding Securities of this
series may declare the principal amount (or, if the Securities of this series
are Original Issue Discount Securities, such portion of the principal amount as
may be specified in the terms of this series) of all the Securities of this
series to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by Holders), provided that, in the case of the
Securities of a series issued to a Lincoln Trust, if upon an Event of Default,
the Trustee or the Holders of not less than 25% in principal amount of the
Outstanding Securities of this series fail to declare the principal of all the
Securities of this series to be immediately due and payable, the holders of at
least 25% in aggregate liquidation amount of the corresponding series of
Preferred Securities then outstanding shall have such right by a notice in
writing to the Company and the Trustee; and upon any such declaration such
specified amount of and the accrued interest (including any Additional Interest)
on all the Securities of this series shall become immediately due and payable,
provided that the payment of principal and interest (including any Additional
Interest) on such Securities shall remain subordinated to the extent provided in
Article Thirteen of the Indenture.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security 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 Security is registrable in the Securities Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company maintained under Section 10.2 of the Indenture duly
endorsed by, 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, and thereupon one or
more new Securities of this series, of authorized denominations and for the same
aggregate principal amount, will be issued to the designated transferee or
transferees. 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 Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name

<PAGE>

this Security is registered as the owner hereof for all purposes, whether or not
this Security be overdue, and neither the Company, the Trustee nor any such
agent shall be affected by notice to the contrary.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $25 and any integral multiple thereof. As provided
in the Indenture and subject to certain limitations therein set forth,
Securities of this series are exchangeable for a like aggregate principal amount
of Securities of such series of a different authorized denomination, as
requested by the Holder surrendering the same.

     The Company and, by its acceptance of this Security or a beneficial
interest therein, the Holder of, and any Person that acquires a beneficial
interest in, this Security agree that for United States federal, state and local
tax purposes it is intended that this Security constitute indebtedness.

     THE INDENTURE AND THIS SECURITY SHALL BE GOVERNED BY AND CONSTRUED IN
ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK WITHOUT REGARD TO CONFLICTS OF
LAWS PRINCIPLES THEREOF.
