 [Reverse of Note] 
 LINCOLN NATIONAL CORPORATION 
 Floating Rate Senior Note due 2010 
 This Note is one of a duly authorized issue of Securities of the Company of a series hereinafter specified, all issued and to be issued under an
Indenture dated as of September 15, 1994, as supplemented by the First Supplemental Indenture dated as of November 1, 2006 (herein collectively called the “Indenture”), between the Company and The Bank of New York, as Trustee
(hereinafter 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 Company, the Trustee and the Holder of the Securities and the terms upon which the Securities are, and are to be, authenticated and delivered. The Securities may be issued in one or more series, the
terms of which different series may vary as provided in the Indenture. This Note is one of a series of the Securities of the Company designated as its Floating Rate Senior Notes due 2010 (herein called the “Notes”), limited in aggregate
principal amount to $250,000,000, except as otherwise provided in the Indenture. The Notes of this series are issuable in registered form only in denominations of $2,000 and integral multiples of $1,000. 
 Three-month LIBOR (“LIBOR”) will be determined by The Bank of New York or a successor financial institution appointed by the Company for such
purpose, as calculation agent (the “Calculation Agent”), in accordance with the following provisions: 
 (a) For each Interest
Period, on the applicable Interest Determination Date (as defined below), the Calculation Agent will determine LIBOR for such Interest Period. LIBOR will be the offered rate (expressed as an interest rate per annum) for three-month U.S. dollar
deposits which appear on Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the second London banking day immediately preceding the first day of such interest payment period. The term “Reuters LIBOR01 Page” means the display on Reuters
LIBOR01 Page or any successor service or page for the purpose of displaying the London interbank offered rates of major banks. 
 (b) If no
offered rate appears on Reuters LIBOR01 Page on any Interest Determination Date at approximately 11:00 A.M., London time, then the Calculation Agent (after consultation with the Company) will select four major banks in the London interbank market
and shall request each of their principal London offices to provide a quotation of the rate at which three-month deposits in U.S. dollars are offered by it to prime banks in the London interbank market, on that date and at that time, that is
representative of single transactions at that time. If at least two quotations are provided, LIBOR will be the arithmetic average of the quotations provided. Otherwise, the Calculation Agent will select three major banks in New York City and shall
request each 

  

 5 







 
of them to provide a quotation of the rate offered by them at approximately 11:00 A.M., New York City time, on such Interest Determination Date for loans in
U.S. dollars to leading European banks having an index maturity of three months for the applicable Interest Period in an amount that is representative of a single transaction at that time. If three quotations are not provided, LIBOR will be set
equal to the rate of LIBOR for the then current Interest Period. 
 Accrued interest on the Notes will be calculated by multiplying the
principal amount of the Notes by an accrued interest factor. The accrued interest factor will be computed by adding the interest factors calculated for each day in an Interest Period. The interest factor for each day is computed by dividing the
interest rate applicable to that day by 360. The interest rate in effect on any Floating Interest Reset Date will be the applicable rate as reset on that date. The interest rate applicable to any other day is the interest rate from the immediately
preceding Floating Interest Reset Date, or if none, the initial floating interest rate. The “Floating Interest Reset Dates” are March 12, June 12, September 12 and December 12 of each year, commencing
June 12, 2007. If any Floating Interest Reset Date falls on a day that is not a London Business Day, such Floating Interest Reset Date will be postponed to the next succeeding London Business Day, except that if such London Business Day is in
the next succeeding calendar month, the Floating Interest Reset Date will be the immediately preceding London Business Day. All percentages used in or resulting from any calculation of the rate of interest on a Note will be rounded, if necessary, to
the nearest one hundred-thousandth of a percentage point (with .000005% rounded up to .00001%), and all U.S. dollar amounts used in or resulting from these calculations will be rounded to the nearest cent (with one-half cent rounded upward).

 For the purposes of calculating LIBOR, “Interest Determination Date” for any Interest Period means the second London Business
Day preceding the Interest Payment Date commencing such Interest Period. 
 Upon request from any Holder of Notes, the Calculation Agent will
provide the interest rate in effect for the Notes for the current Interest Period and, if it has been determined, the interest rate to be in effect for the next Interest Period. Dollar amounts resulting from such calculation will be rounded to the
nearest cent, with one-half cent being rounded upward. 
 Interest on the Notes will be calculated on the basis of the actual number of days
in the applicable period divided by 360. All calculations made by the Calculation Agent for the purposes of calculating interest on the Notes shall be conclusive and binding on the Holders of the Notes, the Trustee and the Company, absent manifest
error. 
 The Notes are not redeemable prior to maturity. 
  

 6 







 The Notes are not entitled to any sinking fund. If an Event of Default shall occur with respect to the
Notes, the principal of the Notes may be declared due and payable in the manner and with the effect provided in the Indenture. 
 The
Indenture contains provisions for defeasance at any time of the Notes, upon which the Company, at its option, shall be deemed to have been Discharged from its obligations with respect to the Notes or shall cease to be under any obligation to comply
with certain restrictive covenants of the Indenture. 
 Subject to certain exceptions, the Indenture or the Notes may be amended or
supplemented with the consent of the Holders of at least a majority in principal amount of the Outstanding Securities affected by such amendment or supplement voting as one class. Without the consent of any Holder, the Company and the Trustee may
amend or supplement the Indenture or the Notes to, among other things, cure any ambiguity, defect or inconsistency. Subject to certain exceptions, any past default or Event of Default may be waived by the Holders of at least a majority in principal
amount of the Outstanding Securities of any series affected on behalf of the Holders of the Securities of that series or the Holders of at least a majority in principal amount of all the Outstanding Securities voting as one class. After the
amendment or supplement is effective, any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the transfer hereof or in exchange
hereunder or in lieu hereof whether or not notation of such consent or waiver is made upon this Note or upon any Note issued upon the transfer hereof or in exchange herefor or in lieu hereof. 
 No reference herein to the Indenture and no provision of this Note 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 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, this Note is transferable on the Security Register of the Company, upon surrender of this Note for transfer at the office or agency of
the Company in The City of New York, New York, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Registrar, duly executed by the Holder hereof or his attorney duly authorizing in
writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees. 
 As provided in the Indenture and subject to certain limitations therein set forth, this Note is exchangeable for a like aggregate principal amount of
Notes of different authorized denominations as requested by the Holder surrendering the same. 
  

 7 







 No service charge will be made for any such 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. 
 The Company, the Trustee and any agent of
the Company or the Trustee may treat the person in whose name this Note is registered as the owner hereof for the purpose of receiving payment as herein provided and for all other purposes whether or not this Note be overdue, and neither the
Company, the Trustee nor any agent shall be affected by notice to the contrary. 
 No recourse shall be had for the payment of the principal
of, or the interest on, this Note or for any claim based hereon or otherwise in any manner in respect hereof, or in respect of the Indenture, against any incorporator, shareholder, officer or director, as such, past, present or future, of the
Company or of any predecessor or, except as provided in the Indenture, successor corporation, whether by virtue of any constitutional provision or statute or rule of law, or by the enforcement of any assessment or penalty or in any other manner, all
such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof. 
 All
capitalized terms used in this Note that are defined in the Indenture shall have the meanings assigned to them in the Indenture.
