                                               No. C-1              $206,186,000

          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 The First National Bank of Chicago, as
Property Trustee of Lincoln National Capital III, or registered assigns, the
principal sum of two hundred six million, one hundred eighty-six thousand
dollars ($206,186,000) on September 30, 2028; PROVIDED, that the Company may
extend the maturity date subject to certain conditions specified in Section 3.14
of the Indenture, which extended maturity date shall in no case be later than
September 30, 2047.  The Company further promises to pay interest on said
principal sum from July 24, 1998 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 September 30, 1998, at the rate of 7.40% 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 7.40% 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 III 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 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 quarters 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.  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.



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

                                           as Trustee

                                           By:    /s/ Barbara G. Grosse

                                [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 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 $206,186,000.

          All terms used in this Security that are defined in the Indenture or
in the Amended and Restated Trust Agreement, dated as of July 24, 1998 (the
"TRUST AGREEMENT"), for Lincoln National Capital III 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 July 24, 2003, 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 III 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 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 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.
