 FIRST SUPPLEMENTAL SUBORDINATED INDENTURE, dated as of [•]2, 2021 (the “First Supplemental Subordinated Indenture”), between Lincoln National Corporation, a corporation duly organized and existing under the laws of the State of Indiana (the
“Company”), and The Bank of New York Mellon , as trustee (the “Trustee”), supplementing the Subordinated Indenture, dated as of [•]3, 2021 (the “Base
Indenture”). 
 WHEREAS, the Company executed and delivered the Base Indenture to the Trustee to provide for the future issuance of the
Company’s subordinated notes, debentures or other evidence of Indebtedness (the “Securities”), to be issued from time to time in one or more series as might be determined by the Company under the Base Indenture; 

WHEREAS, pursuant to a Prospectus dated [•]4, 2021, the Company offered to exchange
any and all of certain capital securities for a new series of the Company’s Securities to be known as its Floating Rate Subordinated Notes due 2066 (the “Subordinated Notes”), which Securities shall be in the form of subordinated
notes issued by the Company; 
 WHEREAS, pursuant to the terms of the Base Indenture and this First Supplemental Subordinated Indenture
(together, the “Indenture”), the Company desires to provide for the establishment of the Subordinated Notes with specific terms and provisions, the form and substance of such Subordinated Notes and the terms, provisions and conditions
thereof to be set forth as provided in the Indenture; and 
 WHEREAS, the Company has requested that the Trustee execute and deliver this
First Supplemental Subordinated Indenture, and all requirements necessary to make this First Supplemental Subordinated Indenture a valid instrument in accordance with its terms, and to make the Subordinated Notes, when executed by the Company and
authenticated and delivered by the Trustee, the valid obligations of the Company, have been done and performed, and the execution and delivery of this First Supplemental Subordinated Indenture has been duly authorized in all respects: 

NOW THEREFORE, in consideration of the tender and acceptance of the Subordinated Notes by the Holders thereof, and for the purpose of setting
forth, as provided in the Indenture, the form and substance of the Subordinated Notes and the terms, provisions and conditions thereof, the Company covenants and agrees with the Trustee as follows: 

 

	2 	 To be dated the exchange offer settlement date. 

	3 	 To be dated the exchange offer settlement date. 

	4 	 Effective date of registration statement. 

 ARTICLE I 

DEFINITIONS 
 Section 1.1
Definition of Terms. 
 Unless the context otherwise requires: 

(a) a term not defined herein that is defined in the Base Indenture has the same meaning when used in this First Supplemental Subordinated
Indenture; 
 (b) the definition of any term in this First Supplemental Subordinated Indenture that is also defined in the Base Indenture
shall supersede the definition of such term in the Base Indenture; 
 (c) a term defined anywhere in this First Supplemental Subordinated
Indenture has the same meaning throughout; 
 (d) the singular includes the plural and vice versa; 

(e) headings are for convenience of reference only and do not affect interpretation; 

(f) the following terms have the meanings given to them in this Section 1.1(e): 

“Benchmark” means, initially, 3-Month LIBOR; provided, that if a Benchmark Transition Event
and its related Benchmark Replacement Date have occurred with respect to 3-Month LIBOR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement. 

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by Company or its designee
as of the Benchmark Replacement Date: 
 (i) the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark
Replacement Adjustment; or 
 (ii) the sum of: (a) the alternate rate of interest that has been selected by the Company
or its designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and
(b) the Benchmark Replacement Adjustment. 
 “Benchmark Replacement Adjustment” means the first alternative set forth in the
order below that can be determined by Company or its designee as of the Benchmark Replacement Date: 
 (i) if the applicable
Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, the ISDA Fallback Adjustment; or 
 (ii) the spread
adjustment (which may be a positive or negative value or zero) that has been selected by Company or its designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment,
for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar denominated floating rate notes at such time. 
  

 
  

  
 -2- 

 “Benchmark Replacement Conforming Changes” means, with respect to any Benchmark
Replacement, any technical, administrative or operational changes (including changes to the definitions or interpretations of interest payment period, the timing and frequency of determining rates and making payments of interest, the rounding of
amounts or tenors, and other administrative matters) that the Company or its designee decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or
its designee decides that adoption of any portion of such market practice is not administratively feasible or if Company or its designee determines that no market practice for use of the benchmark replacement exists, in such other manner as Company
or its designee determines is reasonably practicable). 
 “Benchmark Replacement Date” means the earliest to occur of the
following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof): 

(i) in the case of clause (i) or (ii) of the definition of “Benchmark Transition Event”, the later of
(a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark (or such component); or 

(ii) in the case of clause (iii) of the definition of “Benchmark Transition Event”, the date of the public
statement or publication of information referenced therein. 
 For the avoidance of doubt, if the event giving rise to the Benchmark
Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination. 

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark
(including the daily published component used in the calculation thereof): 
 (i) a public statement or publication of
information by or on behalf of the administrator of the Benchmark (or such component) announcing that such administrator has ceased or will cease to provide the Benchmark (or such component), permanently or indefinitely, provided that, at the time
of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component); 

(ii) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark (or
such component), the central bank for the currency of the Benchmark (or such component), an insolvency official with jurisdiction over the administrator for the Benchmark (or such component), a resolution authority with jurisdiction over the
administrator for the Benchmark (or such component) or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark (or such component), which states that the administrator

  
 -3- 

 
of the Benchmark (or such component) has ceased or will cease to provide the Benchmark (or such component) permanently or indefinitely, provided that, at the time of such statement or
publication, there is no successor administrator that will continue to provide the Benchmark (or such component); or 
 (iii)
a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative. 

“Bloomberg screen HP US0003M” means the display on Bloomberg screen HP US0003M or any successor service or page for the purpose of
displaying the London interbank offered rates of major banks.

regulatory capital.

“Deferral Period” means the period commencing on an Interest Payment Date with respect to which the Company defers interest pursuant
to Section 4.1 and ending on the earlier of (i) the fifth anniversary of that Interest Payment Date and (ii) the next Interest Payment Date on which the Company has paid all deferred and unpaid amounts (including compounded interest
on such deferred amounts) and all other accrued interest on the Subordinated Notes. 
 “Depositary”, with respect to the
Subordinated Notes, means The Depository Trust Company or any successor clearing agency. 
 “First Supplemental Subordinated
Indenture” has the meaning provided in the preamble hereto. 
 “Floating Rate” means the rate of interest on the Subordinated
Notes.

 -4- 

 “Interest Payment Date” means each February 17, May 17, August 17
and November 17, commencing [August 17],5 2021; provided that if any such day from and after the first Interest Payment Date is not a Business Day, then the Interest Payment Date shall be the
next succeeding day that is a Business Day, except that if such Business Day is in the next succeeding calendar month, then such Interest Payment Date will be the immediately preceding Business Day. 

“Interest Payment Period” means the quarterly period from and including an Interest Payment Date to but not including the next
succeeding Interest Payment Date, except for the first Interest Payment Period which shall be determined from and including [May 17,]5 2021 (subject to Section 2.1(b)). 

“ISDA Definitions” means the 2006 ISDA Definitions published by the International Swaps and Derivatives Association, Inc. or any
successor thereto, as amended or supplemented from time to time, or any successor definitional booklet for interest rate derivatives published from time to time. 

“ISDA Fallback Adjustment” means the spread adjustment (which may be a positive or negative value or zero) that would apply for
derivatives transactions referencing the ISDA Definitions to be determined upon the occurrence of an index cessation event with respect to the Benchmark for the applicable tenor. 

“ISDA Fallback Rate” means the rate that would apply for derivatives transactions referencing the ISDA Definitions to be effective
upon the occurrence of an index cessation date with respect to the Benchmark for the applicable tenor excluding the applicable ISDA Fallback Adjustment. 

“LIBOR Determination Date” means 11:00 a.m. (London time) on the second London Banking Day immediately preceding the first day of an
Interest Payment Period. 
 “London Banking Day” means any day on which dealings in deposits in U.S. dollars are transacted in the
London interbank market. 
 “Maturity Date” means the date on which the Subordinated Notes mature as specified in Section 2.2
hereof and on which the principal shall be due and payable together with all accrued and unpaid interest thereon including all compounded interest thereon. 
  

 

	5 	 Initial Interest Payment Date and first Interest Payment Period assume that the expiration date (as defined in
the Registration Statement) occurs on August 9, 2021 and the Subordinated Notes are issued on August 11, 2021. In the event that the record date for an interest payment on the capital securities due 2066 occurs prior to the expiration date
and the related interest payment date would occur thereafter, interest will be paid in full for the entire interest period on the scheduled date for such payment (even if occurring after the settlement date (as defined in the Registration
Statement)), as if such capital securities due 2066 had not been exchanged in the exchange offer, to the holders of record of such capital securities as of the close of business on such record date, and the Subordinated Notes will accrue interest
from and including the date to which such interest is paid. 

  
 -5- 

 “Parity Securities” means Indebtedness of the Company that by its terms ranks in
right of payment upon liquidation of the Company on a parity with the Subordinated Notes, and includes the Subordinated Notes. 

“Rating Agency Event” means that any nationally recognized statistical rating organization within the meaning of
Section 3(a)(62) under the Exchange Act that then publishes a rating for the Company (a “rating agency”) amends, clarifies or changes the criteria it uses to assign equity credit to securities such as the Subordinated Notes, which
amendment, clarification or change results in: 
 (i) the shortening of the length of time the Subordinated Notes are assigned a particular
level of equity credit by that rating agency compared to the length of time they would have been assigned that level of equity credit by that rating agency or its predecessor on the date hereof, or 

(ii) the lowering of the equity credit (including up to a lesser amount) assigned to the Subordinated Notes by that rating agency compared to
the equity credit assigned by that rating agency or its predecessor on the date hereof. 
 “Record Date” has the meaning provided
in Section 2.4(f). 
 “Reference Time” with respect to any determination of the Benchmark means (i) if the Benchmark is 3-Month LIBOR, 11:00 a.m. (London time) on the particular Interest Determination Date, and (ii) if the Benchmark is not 3-Month LIBOR, the time determined by the
Company or its designee in accordance with the Benchmark Replacement Conforming Changes. 
 “Registered Security” means any
Security in the form established pursuant to Section 9.1 hereof which is registered as to principal and interest in the Securities Register. 

“Regulatory Capital Event” means the Company’s good faith determination that, as a result of: 

(i) any amendment to, or change in, the laws, rules or regulations of the United States or any political subdivision of or in the United States
or any other governmental agency or instrumentality as may then have group-wide oversight of the Company’s regulatory capital that is enacted or becomes effective after the date hereof; 

(ii) any proposed amendment to, or change in, those laws, rules or regulations that is announced or becomes effective after the date hereof; or

 (iii) any official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or
applying those laws, rules or regulations that is announced after the date hereof, 
  

  
 -6- 

 there is more than an insubstantial risk that the Company would not be entitled to treat an amount equal to
the full principal amount of the Subordinated Notes outstanding from time to time as “Tier 2 Capital” (or a substantially similar concept) for purposes of the capital adequacy rules of any Capital Regulator to which the Company is or will
be subject; provided that the proposal or adoption of any criterion: 
 (i) that is substantially the same as the corresponding criterion in
the capital adequacy rules of the Board of Governors of the Federal Reserve System applicable to bank holding companies as of the date hereof, or 

(ii) that would result in the full principal amount of the Subordinated Notes outstanding from time to time not qualifying as “Tier 2
Capital” (or a substantially similar concept) for purposes of the capital adequacy rules of the Capital Regulator solely because the Company may redeem the Subordinated Notes at its option upon the occurrence of a Rating Agency Event will not
constitute a Regulatory Capital Event. 
 “Securities” has the meaning set forth in the recitals of this First Supplemental
Subordinated Indenture. 
 “Securities Act” means the Securities Act of 1933, as amended. 

“Subordinated Notes” shall have the meaning set forth in the recitals of this First Supplemental Subordinated Indenture. 

“Tax Event” means the receipt by the Company of an opinion of counsel experienced in such matters to the effect that, as a result of
any: 
 (i) amendment to or change (including any announced prospective change) in the laws or regulations of the United
States or any political subdivision or taxing authority of or in the United States that is enacted or effective on or after the date hereof; 

(ii) official administrative decision or judicial decision or administrative action or other official pronouncement (including
a private letter ruling, technical advice memorandum or other similar pronouncement) by any court, government agency or regulatory authority interpreting or applying those laws or regulations that is announced on or after the date hereof; or 

(iii) threatened challenge asserted in connection with an audit of the Company or any of its Subsidiaries, or a threatened
challenge asserted in writing against any taxpayer that has raised capital through the issuance of securities that are substantially similar to the Subordinated Notes, which challenge is asserted against the Company or becomes publicly known on or
after the date hereof, 
 there is more than an insubstantial increase in the risk that interest accruing or payable by the Company on the Subordinated
Notes is not, or at any time subsequent to the Company’s receipt of such opinion will not be, deductible by the Company, in whole or in part, for U.S. federal income tax purposes. 

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment. 

  
 -7- 

 “3-Month LIBOR,” with respect to an
Interest Payment Period, means the rate (expressed as a percentage per year) for deposits in U.S. dollars for a three-month period that appears on Bloomberg screen HP US0003M as of the relevant LIBOR Determination Date. 

If 3-Month LIBOR cannot be determined for an Interest Payment Period as described above, the Company
will select four major banks in the London interbank market. The Company will request that the principal London offices of those four selected banks provide their offered quotations to prime banks in the London interbank market at approximately
11:00 a.m., London time, on the LIBOR Determination Date for such Interest Payment Period to the Company and the Calculation Agent, and if the Calculation Agent is then not the Trustee, to the Trustee. These quotations will be for deposits in U.S.
dollars for a three-month period. Offered quotations must be based on a principal amount equal to an amount that is representative of a single transaction in U.S. dollars in the market at the time. 

If two or more quotations are provided, 3-Month LIBOR for such Interest Payment Period will be the
arithmetic mean of the quotations. If fewer than two quotations are provided, the Company will select three offered rates quoted by three major banks in New York City on the LIBOR Determination Date for such Interest Payment Period. The rates quoted
will be for loans in U.S. dollars for a three-month period. Rates quoted must be based on a principal amount equal to an amount that is representative of a single transaction in U.S. dollars in the market at the time. Subject to the immediately
following paragraph, if fewer than three New York City banks selected by the Company are quoting rates, 3-Month LIBOR for the applicable Interest Payment Period will be the same as for the immediately
preceding Interest Payment Period. 
 Notwithstanding anything to the contrary, if the Company or its designee determines on or prior to the
relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining 3-Month LIBOR, then the Benchmark Replacement provisions set forth
below under “Effect of Benchmark Transition Event” will thereafter apply to all determinations of the rate of interest payable on the Subordinated Notes. 

“Trustee” shall have the meaning set forth in the preamble of this First Supplemental Subordinated Indenture. 

ARTICLE II 
 GENERAL
TERMS AND CONDITIONS OF THE SUBORDINATED NOTES 
 Section 2.1 Designation and Principal Amount. 

(a) There is hereby authorized a series of Securities designated the Floating Rate Subordinated Notes due 2066, which shall be in the form of
subordinated notes issued by the Company under the Indenture, limited in aggregate principal amount to $[•] which amount shall be as set forth in any written order of the Company for the authentication and delivery of Subordinated Notes
pursuant to Section 3.04 of the Base Indenture. 

  
 -8- 

 (b) The Company may, from time to time, subject to compliance with any other applicable
provisions of this First Supplemental Subordinated Indenture but without the consent of the Holders, create and issue pursuant to this First Supplemental Subordinated Indenture an unlimited principal amount of additional Securities (in excess of any
amounts theretofore issued) having the same terms and conditions to those of the other outstanding Securities, except that any such additional Securities (i) may have a different issue date and issue price from other outstanding Securities and
(ii) may have a different amount of interest payable on the first Interest Payment Date after issuance than is payable on other outstanding Securities. Such additional Securities shall constitute part of the same series of Securities hereunder,
unless any such adjustment pursuant to this Section 2.1(b) shall cause such additional Securities to constitute, as determined pursuant to an opinion of counsel, a different class of securities than the original series of Securities for U.S.
federal income tax purposes. 
 Section 2.2 Maturity. 

The Maturity Date will be May 17, 2066. Notwithstanding the preceding sentence, in the event that the Maturity Date is not a Business Day,
then the Maturity Date will be the next succeeding day which is a Business Day, except that if such Business Day is in the next succeeding calendar month, then the Maturity Date will be the immediately preceding day which is a Business Day. 

Section 2.3 Form and Payment. 

Except as provided in Section 2.4, the Subordinated Notes shall be issued in fully registered definitive form as one or more Global
Securities without interest coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof, bearing identical terms. Principal and interest on the Subordinated Notes issued in certificated form will be payable, the transfer of
such Subordinated Notes will be registrable and such Subordinated Notes will be exchangeable for Subordinated Notes bearing identical terms and provisions at the office or agency of the Trustee; provided, however, that payment of interest may be
made at the option of the Company by check mailed to the Holder at such address as shall appear in the Security Register. 
 Section 2.4 Interest.

 (a) The Subordinated Notes will bear interest at the per annum rate of the Benchmark plus a margin equal to 2.3575% (the
“Floating Rate”), payable quarterly on each Interest Payment Date in respect of an Interest Payment Period, in each case subject to the provisions set forth under Section 2.5. 

(b) The Calculation Agent will calculate the applicable Floating Rate and the amount of interest payable on each quarterly Interest Payment
Date relating to an Interest Payment Period. Promptly upon such determination, the Calculation Agent will notify the Company and, if the Trustee is not then serving as the Calculation Agent, the Trustee, of the Floating Rate for the new quarterly
Interest Payment Period. The Floating Rate determined by the Calculation Agent, absent manifest error, will be binding and conclusive on the Company and the holders of the Subordinated Notes and the Trustee. In the event that any Person acting as
Calculation Agent shall be unable or unwilling to act, or that such Person shall fail to duly calculate the interest rate for any Interest Payment Period, or the Company proposes to remove such Person as Calculation Agent, the Company shall appoint
a successor Calculation Agent (which may be the Company or one of its Affiliates). 

  
 -9- 

 (c) Interest payments will include accrued interest from and including the last date in
respect of which interest has been paid or duly provided for to, but not including, the next succeeding Interest Payment Date, the date of redemption or the Maturity Date, as the case may be; provided, however, that the amount of interest
payable for the first Interest Payment Period shall be determined from and including [May 17]5, 2021. The amount of interest payable will be computed on the basis of a 360-day year and the actual number of days elapsed in each quarterly Interest Payment Period. All percentages resulting from any interest rate calculation will be rounded upward or downward, as appropriate, to the
next higher or lower one-hundred-thousandth of a percentage point. 
 (d) Otherwise than in
connection with the maturity or early redemption of the Subordinated Notes or the payment in whole or in part of deferred or overdue interest on the Subordinated Notes, interest on the Subordinated Notes may be paid only on an Interest Payment Date.

 (e) To the extent permitted by applicable law, interest not paid when due hereunder, including, without limitation, all interest deferred
pursuant to Section 4.1, will accrue and compound quarterly at the applicable Coupon Rate on each Interest Payment Date until paid. References to “interest” in the Base Indenture and this First Supplemental Subordinated Indenture
include references to such compounded interest. 
 (f) The interest installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Base Indenture, be paid to the Person in whose name the Subordinated Notes is registered at the close of business on the day next preceding the Interest Payment Date; provided, that in the event the
Subordinated Notes will not continue to remain in book-entry form or are not in the form of a Global Certificate, the record date for each Interest Payment Date shall be the first day of the month in which such Interest Payment Date occurs (in each
case, the applicable “Record Date”). Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such Record Date, and may be paid to the Person in whose name the
Subordinated Notes is registered at the close of business on a special record date to be fixed by the Trustee for the payment of such defaulted interest after the Company has deposited with the Trustee an amount of money equal to the aggregate
amount proposed to be paid in respect of such defaulted interest, notice whereof shall be given to the registered Holders of this series of Subordinated Notes not less than ten days prior to such special record date, or may be paid at any time in
any other lawful manner not inconsistent with the requirements of any securities exchange on which the Subordinated Notes may be listed, and upon such notice as may be required by such exchange.

 Section 2.5 Effect of Benchmark Transition Event 

(a) Benchmark Replacement. If the Company or its designee determines that a Benchmark Transition Event and its related Benchmark
Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Subordinated Notes in respect
of such determination on such date and all determinations on all subsequent dates. 
 (b) Benchmark Replacement Conforming Changes. In
connection with the implementation of a Benchmark Replacement, the Company or its designee will have the right to make Benchmark Replacement Conforming Changes from time to time without the consent of the Holders of the Subordinated Notes or the
Trustee. 
 (c) Decisions and Determinations. Any determination, decision or election that may be made by the Company or its designee
pursuant to the Benchmark Transition provisions described herein, including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date
and any decision to take or refrain from taking any action or any selection: 
 (i) will be conclusive and binding absent manifest error;

 (ii) if made by the Company, will be made in the Company’s sole discretion; 

(iii) if made by the Company’s designee, will be made after consultation with the Company, and such designee will not make any such
determination, decision or election to which the Company objects; and 
 (iv) notwithstanding anything to the contrary herein or in the
Subordinated Notes, shall become effective without consent from the Holders of the Subordinated Notes or any other party. 
 (d) Any
determination, decision or election pursuant to the Benchmark Replacement provisions set forth in this Section 2.5 shall be made by the Company or its designee (which may be the Company’s Affiliate) on the basis described above, and in no
event shall the Trustee, any Paying Agent or the Calculation Agent be responsible for making any such determination, decision or election. The Company may, in its sole discretion, designate any Affiliate of the Company or any other person to make
one or more determinations, decisions or elections on a temporary or permanent basis, and the Company may, in its sole discretion, revoke any such designation. Any person so designated in accordance with the immediately preceding sentence will be a
“designee” for purposes of these provisions addressing the effect of a Benchmark Transition Event for so long as such designation remains in effect. 

(e) None of the Trustee, any Paying Agent or the Calculation Agent shall be under any obligation to (i) monitor, determine or verify the
unavailability or cessation of 3-Month LIBOR, or whether or when there has occurred, or to give notice to any other Person of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement
Date, (ii) select, determine or designate any Benchmark Replacement, or other successor or 

  
 -11- 

 
replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, (iii) select, determine or designate any Benchmark Replacement
Adjustment, or other modifier to any replacement index, or (iv) determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing, including, but not limited to,
adjustments as to any alternative spread thereon, the business day convention, interest determination dates or any other relevant methodology applicable to such substitute or successor Benchmark. In connection with the foregoing, each of the
Trustee, any Paying Agent and the Calculation Agent shall be entitled to conclusively rely on any determinations made by the Company or its designee without independent investigation, and none will have any liability for actions taken at the
direction of the Company in connection therewith. 
 (f) None of the Trustee, any Paying Agent or the Calculation Agent shall be liable for
any inability, failure or delay on its part to perform any of its duties set forth in this First Supplemental Subordinated Indenture or the Base Indenture as a result of the unavailability of 3-Month LIBOR or
other applicable Benchmark, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other Person in providing any direction, instruction, notice or information required or contemplated by the terms of this
First Supplemental Indenture or the Base Indenture and reasonably required for the performance of such duties. None of the Trustee, Paying Agent or Calculation Agent shall be responsible or liable for the actions of the Company or omissions or for
those of the Company’s designee, or for any failure or delay in the performance by the Company or its designee, nor shall any of the Trustee, Paying Agent or Calculation Agent be under any obligation to oversee or monitor the performance of the
Company or that of the Company’s designee.

	6 	 The date that is five years after the issuance date of the Subordinated Notes. 

  
 -12- 

 (ii) in whole, but not in part, at any time prior to [•], 2026,6 within 90 days after the occurrence of a Tax Event or a Regulatory Capital Event at a redemption price equal to the principal amount of the Subordinated Notes being redeemed plus accrued and unpaid
interest to but excluding the Redemption Date; or

 provided, in each case, that all accrued and unpaid interest, including deferred interest (and compounded
interest thereon) shall have been paid in full on all Outstanding Subordinated Notes for all Interest Payment Periods ending on or before the Redemption Date. In the event the Subordinated Notes are treated as “Tier 2 Capital” (or a
substantially similar concept) under the capital rules of any Capital Regulator applicable to the Company, any redemption of the Subordinated Notes shall be subject to the Company’s receipt of any required prior approval from such Capital
Regulator and to the satisfaction of any conditions set forth in those capital rules and any other applicable regulations of any other Capital Regulator that are applicable to the Company’s redemption of the Subordinated Notes.

 OPTIONAL
DEFERRAL OF INTEREST 
 Section 4.1 Optional Deferral of Interest.

elect, at any time and from time to time, to defer the payment of interest on the Subordinated Notes for one or more consecutive Interest Payment Periods that do not exceed five years for any single Deferral Period, provided that no Deferral Period
shall extend beyond the Maturity Date, any earlier accelerated maturity date arising from an Event of Default or any other earlier redemption of the Subordinated Notes. If the Company has paid all deferred interest (including compounded interest
thereon) on the Subordinated Notes, the Company shall have the right to elect to begin a new Deferral Period pursuant to this Section 4.1. 

(b) At the end of any Deferral Period, the Company shall pay all accrued and unpaid deferred interest (including compounded interest thereon)

relevant Interest Payment Date. Such notice of deferral, once given, will be irrevocable and the deferral of payments on the related Interest Payment Date will be considered a deferral subject to Section 4.1 above.

 EVENTS OF
DEFAULT 
 Section 5.1 Events of Default. 

(a) Section 5.01 of the Base Indenture shall apply to the Subordinated Notes. 

(b) The Trustee shall provide to the Holders of the Subordinated Notes notice of any Event of Default or default with respect to the
Subordinated Notes within 90 days after the actual knowledge of a Responsible Trust Officer of the Trustee of such Event of Default or default. However, except in the case of a default in payment on the Subordinated Notes, the Trustee will be
protected in withholding the notice if its Responsible Trust Officers determine that withholding of the notice is in the interest of such Holders. 

(c) The Trustee shall have no right or obligation under the Indenture or otherwise to exercise any remedies on behalf of any Holders of the
Subordinated Notes pursuant to the Indenture in connection with any default, unless such remedies are available under the Indenture and the Trustee is directed to exercise such remedies pursuant to and subject to the conditions of Section 5.12
of the Base Indenture, provided, however, that this provision shall not affect the rights of the Trustee with respect to any Events of Default as set forth in Section 5.01 of the Base Indenture that may occur with
respect to the Subordinated Notes. In connection with any such exercise of remedies the Trustee shall be entitled to the same immunities and protections and remedial rights (other than acceleration) as if such default were an Event of Default. 

(d) For purposes of this Section 5.1, the term “default” means any of the following events: 

(i) the failure to pay interest, including compounded interest, in full on any Subordinated Notes for a period of 30 days after the conclusion

shares of Capital Stock of the Company;

redeem any of the Company’s debt securities that rank upon the Company’s liquidation on a parity with or junior to the Subordinated Notes; or

 (A) any purchase, redemption or other acquisition of shares of the Company’s Capital Stock
by the Company in connection with: 
 (1) any employment contract, benefit plan or other similar arrangement with or for the benefit of any
one or more of its employees, officers, directors, consultants or independent contractors;

options or other rights is the same stock as that on which the dividend is being paid or ranks equally with or junior to such stock; or 

(F) (i) any payment of current or deferred interest on Parity Securities that is made pro rata to the amounts
due on such Parity Securities (including the Subordinated Notes) and (ii) any payments of principal or current or deferred interest on Parity Securities that, if not made, would cause the Company to breach the terms of the
instrument governing such Parity Securities.

Subordinated Notes will restrict in any manner the ability of any of the Subsidiaries to pay dividends to the Company or any other Subsidiaries or make any distributions to the Company or to any other Subsidiaries. 

Section 6.2 [Reserved.] 
 Section 6.3 Payment

 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 _____________________________________________________, or registered assigns, the
principal sum of __________________________ dollars ($____________) on May 17, 2066 (the “Maturity Date”). Notwithstanding the preceding sentence, in the event that the Maturity 

  
 -17- 

 
Date is not a Business Day, then the Maturity Date will be the next succeeding day which is a Business Day, except if such Business Day is in the next succeeding calendar month then the Maturity
Date will be the immediately preceding day which is a Business Day. The Subordinated Notes will bear interest at the per annum rate of 3-Month LIBOR plus a margin equal to 2.3575% (the “Floating
Rate”), payable quarterly on February 17, May 17, August 17 and November 17. Interest payments in respect of Interest Payment Periods will include accrued interest from and including the last date in respect of which interest has
been paid or duly provided for to, but not including, the next succeeding Interest Payment Date or the Maturity Date, as the case may be; provided, however, that the amount of interest payable for the first Interest Payment Period shall be
determined from and including [May 17]7, 2021. The amount of interest payable will be computed on the basis of a 360-day year and the actual number of days
elapsed in each quarterly Interest Payment Period. All percentages resulting from any interest rate calculation will be rounded upward or downward, as appropriate, to the next higher or lower
one-hundred-thousandth of a percentage point. If any Interest Payment Date is not a Business Day, then the Interest Payment Date shall be the immediately succeeding Business Day, except that if such Business
Day is in the next succeeding calendar month then such Interest Payment Date will be the immediately preceding Business Day. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Base Indenture, be paid to the Person in whose name this Subordinated Note is registered at the close of business on the day next preceding the Interest Payment Date; provided, that in the event the Subordinated Notes will not
continue to remain in book-entry form or are not in the form of a Global Certificate, the record date for each Interest Payment Date shall be the first day of the month in which such Interest Payment Date occurs (in each case, the applicable
“Record Date”). Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such record date, and may be paid to the Person in whose name this Subordinated Note is
registered at the close of business on a special record date to be fixed by the Trustee for the payment of such defaulted interest after the Company has deposited with the Trustee an amount of money equal to the aggregate amount proposed to be paid
in respect of such defaulted interest, notice whereof shall be given to the registered Holders of this series of Subordinated Notes not less than ten days prior to such special record date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Subordinated Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. The principal of (and premium, if
any) and the interest (including any compounded interest thereon) on this Subordinated Note shall be payable at the office or agency of the Trustee maintained for that purpose in the United States, in any coin or currency of the United States of
America which at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered Holder at such address as shall
appear in the Security Register. 
  

	7 	 Initial Interest Payment Date and first Interest Payment Period assume that the expiration date (as defined in
the Registration Statement) occurs on August 9, 2021 and the Subordinated Notes are issued on August 11, 2021. In the event that the record date for an interest payment on the capital securities due 2066 occurs prior to the expiration date
and the related interest payment date would occur thereafter, interest will be paid in full for the entire interest period on the scheduled date for such payment (even if occurring after the settlement date (as defined in the Registration
Statement)), as if such capital securities due 2066 had not been exchanged in the exchange offer, to the holders of record of such capital securities as of the close of business on such record date, and the Subordinated Notes will accrue interest
from and including the date to which such interest is paid. 

  
 -18- 

 The Indebtedness evidenced by this Subordinated Note is, to the extent provided in the
Indenture, subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness, and this Subordinated Note is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Subordinated
Note, 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 action as may be necessary or appropriate to acknowledge or 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, hereby waives all notice of
the acceptance of the subordination provisions contained herein and in the Indenture by each Holder of Senior Indebtedness, 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 Subordinated 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. 
 Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual, facsimile or electronic signature, this Subordinated Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 [REVERSE OF NOTE] 

This Note is one of a duly authorized issue of securities of the Company (herein called the “Subordinated Notes”), issued and to be
issued in one or more series under a Subordinated Indenture, dated as of ___, 2021 (herein called the “Base Indenture”), between the Company and The Bank of New York Mellon (herein called the “Trustee”, which term includes any
successor trustee under the Indenture), as supplemented by a First Supplemental Subordinated Indenture, dated as of ___, 2021 (the “First Supplemental Subordinated Indenture” and the Base Indenture as so supplemented, 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 Subordinated Notes, and of the terms upon which the Subordinated Notes are, and are to be, authenticated and delivered. This Subordinated Note is one of the series designated on the face hereof, limited in aggregate principal amount to
$__________. 
 All terms used in this Subordinated Note that are defined in the Indenture shall have the meanings assigned to them in the
Indenture. 
 The Company shall have the right, at its option, to redeem the Subordinated Notes for cash: 

(a) in whole at any time or in part from time to time on or after [•], 2026,9 at a
redemption price equal to 100% of the principal amount of the Subordinated Notes being redeemed plus accrued and unpaid interest to but excluding the Redemption Date; provided that if the Subordinated Notes are not redeemed in whole, at least
$25 million aggregate principal amount of the Subordinated Notes (excluding any Subordinated Notes held by the Company or any of its Affiliates) remains Outstanding after giving effect to such redemption; 

(b) in whole, but not in part, at any time prior to [•], 2026,9 within 90 days after
the occurrence of a Tax Event or a Regulatory Capital Event, at a redemption price equal to 100% of the principal amount of the Subordinated Notes being redeemed plus accrued and unpaid interest to but excluding the Redemption Date; or 

(c) in whole, but not in part, at any time prior to [•], 2026,9 within 90 days after
the occurrence of a Rating Agency Event, at a redemption price equal to 102% of the principal amount of the Subordinated Notes being redeemed plus accrued and unpaid interest to but excluding the Redemption Date. 

Notwithstanding the foregoing, the Company may not redeem the Subordinated Notes unless all accrued and unpaid interest, including deferred
interest (and compounded interest thereon), has been paid in full on all Outstanding Subordinated Notes for all Interest Payment Periods ending on or before the Redemption Date. 

 
  

	9 	 The date that is five years after the issuance date of the Subordinated Notes.

  
 -21- 

 The Company will prepare and mail a notice of redemption to each Holder of Subordinated
Notes to be redeemed by first-class mail at least 15 but not more than 60 days prior to the date fixed for redemption. On and after a Redemption Date, interest will cease to accrue on the Subordinated Notes called for redemption (unless the Company
defaults in the payment of the redemption price and accrued interest (including any compounded interest thereon)). On or before a Redemption Date, the Company will deposit with a Paying Agent (or the Trustee) money sufficient to pay the redemption
price of and accrued interest (including any compounded interest thereon) on the Subordinated Notes to be redeemed on that date. If less than all of the Subordinated Notes are to be redeemed, the Subordinated Notes to be redeemed shall be selected
by the Trustee by lot; provided that, to the extent the Subordinated Notes to be redeemed are represented by a Global Certificate, such Subordinated Notes shall be selected in accordance with the procedures of DTC. 

The Subordinated Notes are not entitled to the benefit of any sinking fund. 

If an Event of Default with respect to Subordinated Notes of this series shall occur and be continuing, the principal of the Subordinated
Notes 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 Subordinated Note
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 Subordinated Note shall be conclusive and binding upon such Holder and upon all future Holders of this Subordinated Note and of any Subordinated Note 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 Subordinated Note. 

So long as no Event of Default with respect to this Subordinated Note has occurred or is continuing, the Company shall have the right at any
time during the term of this Subordinated Note to defer payment of interest on this Subordinated Note for one or more consecutive Interest Periods that do not exceed five years for any single Deferral Period, during which 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; provided, however, that no Deferral Period shall extend beyond the Maturity Date or
the earlier accelerated maturity date arising from an Event of Default or redemption of this Subordinated Note. Upon the termination of any Deferral Period and upon the payment of all deferred interest then due, the Company may elect to begin a new
Deferral Period, subject to the above requirements. 

  
 -22- 

 So long as any Subordinated Notes of this series remain outstanding, if the Company has
given notice of its election to defer interest payments on the Subordinated Notes but the related Deferral Period has not yet commenced or a Deferral Period is continuing, the Company shall not, and shall not permit any Subsidiary to,
(i) declare or pay any dividends or other distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any shares of the Company’s Capital Stock, (ii) make any payment of principal of, or interest or
premium, if any, on or repay, purchase or redeem any debt securities of the Company that rank upon the Company’s liquidation on a parity with this Subordinated Note or junior to this Subordinated Note or (iii) make any guarantee payments
regarding any guarantee issued by the Company of securities of any Subsidiary if the guarantee ranks upon the Company’s liquidation on a parity with or junior to this Subordinated Note (other than (a) any purchase, redemption or other
acquisition of shares of its Capital Stock in connection with (1) any employment contract, benefit plan or other similar arrangement with or for the benefit of any one or more of its employees, officers, directors, consultants or independent
contractors, (2) the satisfaction of the Company’s obligations pursuant to any contract entered into prior to the beginning of the applicable Deferral Period, (3) a dividend reinvestment or shareholder purchase plan, or (4) the
issuance of shares of the Company’s Capital Stock, or securities convertible into or exercisable for such shares, as consideration in an acquisition transaction entered into prior to the applicable Deferral Period, (b) any exchange,
redemption or conversion of any class or series of the Company’s Capital Stock, or the Capital Stock of one of its Subsidiaries, for any other class or series of its Capital Stock, or of any class or series of its Indebtedness for any class or
series of its Capital Stock, (c) any purchase of fractional interests in shares of the Company’s Capital Stock pursuant to the conversion or exchange provisions of such shares or the securities being converted or exchanged, (d) any
declaration of a dividend in connection with any shareholder rights plan, or the issuance of rights, stock or other property under any shareholder rights plan, or the redemption or purchase of rights pursuant thereto, (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks equally with or junior to such
stock, or (f) (1) any payment of current or deferred interest on Parity Securities that is made pro rata to the amounts due on such Parity Securities (including the Notes), and (2) any payments of principal or current or deferred interest
on Parity Securities that, if not made, would cause the Company to breach the terms of the instrument governing such Parity Securities). 

The Company shall give written notice of its election to commence or continue any Deferral Period to the Trustee and the Holders of all
Securities of this series then Outstanding at least five days (in the case of the Trustee) or fifteen days (in the case of the Holders) and not more than 60 days, in each case, before the next Interest Payment Date. Such notice shall be given to the
Trustee and the Holder of this Security at such Holder’s address appearing in the Security Register by first-class mail, postage prepaid (or, as long as the Notes are held through DTC, transmitted in accordance with applicable procedures of
DTC). 
 Except as provided in the immediately preceding paragraph and Article XI of the First Supplemental Subordinated Indenture, no
reference herein to the Indenture and no provision of this Subordinated 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 premium, if any) and interest on

DEFINITIONS 
 Section 1.1
Definition of Terms. 
 Unless the context otherwise requires: 

(a) a term not defined herein that is defined in the Base Indenture has the same meaning when used in this Second Supplemental Subordinated
Indenture; 
 (b) the definition of any term in this Second Supplemental Subordinated Indenture that is also defined in the Base Indenture
shall supersede the definition of such term in the Base Indenture; 
 (c) a term defined anywhere in this Second Supplemental Subordinated
Indenture has the same meaning throughout; 
 (d) the singular includes the plural and vice versa; 

(e) headings are for convenience of reference only and do not affect interpretation; 

(f) the following terms have the meanings given to them in this Section 1.1(e): 

“Benchmark” means, initially, 3-Month LIBOR; provided, that if a Benchmark Transition Event
and its related Benchmark Replacement Date have occurred with respect to 3-Month LIBOR or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement. 

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by Company or its designee
as of the Benchmark Replacement Date: 
 (i) the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark
Replacement Adjustment; or 
 (ii) the sum of: (a) the alternate rate of interest that has been selected by the Company
or its designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and
(b) the Benchmark Replacement Adjustment. 
 “Benchmark Replacement Adjustment” means the first alternative set forth in the
order below that can be determined by Company or its designee as of the Benchmark Replacement Date: 
 (i) if the applicable
Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, the ISDA Fallback Adjustment; or 
 (ii) the spread
adjustment (which may be a positive or negative value or zero) that has been selected by Company or its designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment,
for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar denominated floating rate notes at such time. 

  
 -2- 

 “Benchmark Replacement Conforming Changes” means, with respect to any Benchmark
Replacement, any technical, administrative or operational changes (including changes to the definitions or interpretations of interest payment period, the timing and frequency of determining rates and making payments of interest, the rounding of
amounts or tenors, and other administrative matters) that the Company or its designee decides may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or
its designee decides that adoption of any portion of such market practice is not administratively feasible or if Company or its designee determines that no market practice for use of the benchmark replacement exists, in such other manner as Company
or its designee determines is reasonably practicable). 
 “Benchmark Replacement Date” means the earliest to occur of the
following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof):

(ii) in the case of clause (iii) of the definition of “Benchmark Transition Event”, the date of the public
statement or publication of information referenced therein. 
 For the avoidance of doubt, if the event giving rise to the Benchmark
Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination. 

“Benchmark Transition Event” means the occurrence of one or more of the following events with respect to the then-current Benchmark
(including the daily published component used in the calculation thereof):

of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component); 

(ii) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark (or
such component), the central bank for the currency of the Benchmark (or such component), an insolvency official with jurisdiction over the administrator for the Benchmark (or such component), a resolution authority with jurisdiction over the
administrator for the Benchmark (or such component) or a court or an entity with similar insolvency or resolution authority over the administrator for the Benchmark (or such component), which states that the administrator of the Benchmark (or such
component) has ceased or will cease to provide the Benchmark (or such component) permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the
Benchmark (or such component); or

on such deferred amounts) and all other accrued interest on the Subordinated Notes. 
 “Depositary”, with respect to the
Subordinated Notes, means The Depository Trust Company or any successor clearing agency.

	5 	 Initial Interest Payment Date and first Interest Payment Period assume that the expiration date (as defined in
the Registration Statement) occurs on August 9, 2021 and the Subordinated Notes are issued on August 11, 2021. In the event that the record date for an interest payment on the capital securities due 2067 occurs prior to the expiration date
and the related interest payment date would occur thereafter, interest will be paid in full for the entire interest period on the scheduled date for such payment (even if occurring after the settlement date (as defined in the Registration
Statement)), as if such capital securities due 2067 had not been exchanged in the exchange offer, to the holders of record of such capital securities as of the close of business on such record date, and the Subordinated Notes will accrue interest
from and including the date to which such interest is paid. 

  
 -5- 

 “Rating Agency Event” means that any nationally recognized statistical rating
organization within the meaning of Section 3(a)(62) under the Exchange Act that then publishes a rating for the Company (a “rating agency”) amends, clarifies or changes the criteria it uses to assign equity credit to securities such
as the Subordinated Notes, which amendment, clarification or change results in: 
 (i) the shortening of the length of time the Subordinated
Notes are assigned a particular level of equity credit by that rating agency compared to the length of time they would have been assigned that level of equity credit by that rating agency or its predecessor on the date hereof, or 

(ii) the lowering of the equity credit (including up to a lesser amount) assigned to the Subordinated Notes by that rating agency compared to
the equity credit assigned by that rating agency or its predecessor on the date hereof. 
 “Record Date” has the meaning provided
in Section 2.4(f). 
 “Reference Time” with respect to any determination of the Benchmark means (i) if the Benchmark is 3-Month LIBOR, 11:00 a.m. (London time) on the particular Interest Determination Date, and (ii) if the Benchmark is not 3-Month LIBOR, the time determined by the
Company or its designee in accordance with the Benchmark Replacement Conforming Changes. 
 “Registered Security” means any
Security in the form established pursuant to Section 9.1 hereof which is registered as to principal and interest in the Securities Register. 

“Regulatory Capital Event” means the Company’s good faith determination that, as a result of: 

(i) any amendment to, or change in, the laws, rules or regulations of the United States or any political subdivision of or in the United States
or any other governmental agency or instrumentality as may then have group-wide oversight of the Company’s regulatory capital that is enacted or becomes effective after the date hereof; 

(ii) any proposed amendment to, or change in, those laws, rules or regulations that is announced or becomes effective after the date hereof; or

 (iii) any official administrative decision or judicial decision or administrative action or other official pronouncement interpreting or
applying those laws, rules or regulations that is announced after the date hereof, 
 there is more than an insubstantial risk that the Company would not be
entitled to treat an amount equal to the full principal amount of the Subordinated Notes outstanding from time to time as “Tier 2 Capital” (or a substantially similar concept) for purposes of the capital adequacy rules of any Capital
Regulator to which the Company is or will be subject; provided that the proposal or adoption of any criterion: 
 (i) that is substantially
the same as the corresponding criterion in the capital adequacy rules of the Board of Governors of the Federal Reserve System applicable to bank holding companies as of the date hereof, or 

  
 -6- 

 (ii) that would result in the full principal amount of the Subordinated Notes outstanding
from time to time not qualifying as “Tier 2 Capital” (or a substantially similar concept) for purposes of the capital adequacy rules of the Capital Regulator solely because the Company may redeem the Subordinated Notes at its option upon
the occurrence of a Rating Agency Event will not constitute a Regulatory Capital Event. 
 “Second Supplemental Subordinated
Indenture” has the meaning provided in the preamble hereto. 
 “Securities” has the meaning set forth in the recitals of this
Second Supplemental Subordinated Indenture. 
 “Securities Act” means the Securities Act of 1933, as amended. 

“Subordinated Notes” shall have the meaning set forth in the recitals of this Second Supplemental Subordinated Indenture. 

“Tax Event” means the receipt by the Company of an opinion of counsel experienced in such matters to the effect that, as a result of
any: 
 (i) amendment to or change (including any announced prospective change) in the laws or regulations of the United
States or any political subdivision or taxing authority of or in the United States that is enacted or effective on or after the date hereof; 

(ii) official administrative decision or judicial decision or administrative action or other official pronouncement (including
a private letter ruling, technical advice memorandum or other similar pronouncement) by any court, government agency or regulatory authority interpreting or applying those laws or regulations that is announced on or after the date hereof; or 

(iii) threatened challenge asserted in connection with an audit of the Company or any of its Subsidiaries, or a threatened
challenge asserted in writing against any taxpayer that has raised capital through the issuance of securities that are substantially similar to the Subordinated Notes, which challenge is asserted against the Company or becomes publicly known on or
after the date hereof, 
 there is more than an insubstantial increase in the risk that interest accruing or payable by the Company on the Subordinated
Notes is not, or at any time subsequent to the Company’s receipt of such opinion will not be, deductible by the Company, in whole or in part, for U.S. federal income tax purposes. 

“Unadjusted Benchmark Replacement” means the Benchmark Replacement excluding the Benchmark Replacement Adjustment. 

“3-Month LIBOR,” with respect to an Interest Payment Period, means the rate (expressed as a
percentage per year) for deposits in U.S. dollars for a three-month period that appears on Bloomberg screen HP US0003M as of the relevant LIBOR Determination Date. 

  
 -7- 

 If 3-Month LIBOR cannot be determined for an
Interest Payment Period as described above, the Company will select four major banks in the London interbank market. The Company will request that the principal London offices of those four selected banks provide their offered quotations to prime
banks in the London interbank market at approximately 11:00 a.m., London time, on the LIBOR Determination Date for such Interest Payment Period to the Company and the Calculation Agent, and if the Calculation Agent is then not the Trustee, to the
Trustee. These quotations will be for deposits in U.S. dollars for a three-month period. Offered quotations must be based on a principal amount equal to an amount that is representative of a single transaction in U.S. dollars in the market at the
time. 
 If two or more quotations are provided, 3-Month LIBOR for such Interest Payment Period will
be the arithmetic mean of the quotations. If fewer than two quotations are provided, the Company will select three offered rates quoted by three major banks in New York City on the LIBOR Determination Date for such Interest Payment Period. The rates
quoted will be for loans in U.S. dollars for a three-month period. Rates quoted must be based on a principal amount equal to an amount that is representative of a single transaction in U.S. dollars in the market at the time. Subject to the
immediately following paragraph, if fewer than three New York City banks selected by the Company are quoting rates, 3-Month LIBOR for the applicable Interest Payment Period will be the same as for the
immediately preceding Interest Payment Period. 
 Notwithstanding anything to the contrary, if the Company or its designee determines on or
prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining 3-Month LIBOR, then the Benchmark Replacement
provisions set forth below under “Effect of Benchmark Transition Event” will thereafter apply to all determinations of the rate of interest payable on the Subordinated Notes. 

“Trustee” shall have the meaning set forth in the preamble of this Second Supplemental Subordinated Indenture. 

ARTICLE II 
 GENERAL
TERMS AND CONDITIONS OF THE SUBORDINATED NOTES 
 Section 2.1 Designation and Principal Amount. 

(a) There is hereby authorized a series of Securities designated the Floating Rate Subordinated Notes due 2067, which shall be in the form of
subordinated notes issued by the Company under the Indenture, limited in aggregate principal amount to $[•] which amount shall be as set forth in any written order of the Company for the authentication and delivery of Subordinated Notes
pursuant to Section 3.04 of the Base Indenture. 
 (b) The Company may, from time to time, subject to compliance with any other
applicable provisions of this Second Supplemental Subordinated Indenture but without the consent of the Holders, create and issue pursuant to this Second Supplemental Subordinated Indenture an unlimited principal amount of additional Securities (in
excess of any amounts theretofore issued) having the same terms and conditions to those of the other outstanding 

  
 -8- 

 
Securities, except that any such additional Securities (i) may have a different issue date and issue price from other outstanding Securities and (ii) may have a different amount of
interest payable on the first Interest Payment Date after issuance than is payable on other outstanding Securities. Such additional Securities shall constitute part of the same series of Securities hereunder, unless any such adjustment pursuant to
this Section 2.1(b) shall cause such additional Securities to constitute, as determined pursuant to an opinion of counsel, a different class of securities than the original series of Securities for U.S. federal income tax purposes. 

Section 2.2 Maturity. 
 The Maturity
Date will be April 20, 2067. Notwithstanding the preceding sentence, in the event that the Maturity Date is not a Business Day, then the Maturity Date will be the next succeeding day which is a Business Day, except that if such Business Day is
in the next succeeding calendar month, then the Maturity Date will be the immediately preceding day which is a Business Day. 
 Section 2.3 Form and
Payment. 
 Except as provided in Section 2.4, the Subordinated Notes shall be issued in fully registered definitive form as one or
more Global Securities without interest coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof, bearing identical terms. Principal and interest on the Subordinated Notes issued in certificated form will be payable, the
transfer of such Subordinated Notes will be registrable and such Subordinated Notes will be exchangeable for Subordinated Notes bearing identical terms and provisions at the office or agency of the Trustee; provided, however, that payment of
interest may be made at the option of the Company by check mailed to the Holder at such address as shall appear in the Security Register. 

Section 2.4 Interest. 
 (a) The
Subordinated Notes will bear interest at the per annum rate of the Benchmark plus a margin equal to 2.0400% (the “Floating Rate”), payable quarterly on each Interest Payment Date in respect of an Interest Payment Period, in each case
subject to the provisions set forth under Section 2.5. 
 (b) The Calculation Agent will calculate the applicable Floating Rate and the
amount of interest payable on each quarterly Interest Payment Date relating to an Interest Payment Period. Promptly upon such determination, the Calculation Agent will notify the Company and, if the Trustee is not then serving as the Calculation
Agent, the Trustee, of the Floating Rate for the new quarterly Interest Payment Period. The Floating Rate determined by the Calculation Agent, absent manifest error, will be binding and conclusive on the Company and the holders of the Subordinated
Notes and the Trustee. In the event that any Person acting as Calculation Agent shall be unable or unwilling to act, or that such Person shall fail to duly calculate the interest rate for any Interest Payment Period, or the Company proposes to
remove such Person as Calculation Agent, the Company shall appoint a successor Calculation Agent (which may be the Company or one of its Affiliates). 

  
 -9- 

 (c) Interest payments will include accrued interest from and including the last date in
respect of which interest has been paid or duly provided for to, but not including, the next succeeding Interest Payment Date, the date of redemption or the Maturity Date, as the case may be; provided, however, that the amount of interest
payable for the first Interest Payment Period shall be determined from and including [July 20]5, 2021. The amount of interest payable will be computed on the basis of a 360-day year and the actual number of days elapsed in each quarterly Interest Payment Period. All percentages resulting from any interest rate calculation will be rounded upward or downward, as appropriate, to the
next higher or lower one-hundred-thousandth of a percentage point. 
 (d) Otherwise than in
connection with the maturity or early redemption of the Subordinated Notes or the payment in whole or in part of deferred or overdue interest on the Subordinated Notes, interest on the Subordinated Notes may be paid only on an Interest Payment Date.

 (e) To the extent permitted by applicable law, interest not paid when due hereunder, including, without limitation, all interest deferred
pursuant to Section 4.1, will accrue and compound quarterly at the applicable Coupon Rate on each Interest Payment Date until paid. References to “interest” in the Base Indenture and this Second Supplemental Subordinated Indenture
include references to such compounded interest. 
 (f) The interest installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Base Indenture, be paid to the Person in whose name the Subordinated Notes is registered at the close of business on the day next preceding the Interest Payment Date; provided, that in the event the
Subordinated Notes will not continue to remain in book-entry form or are not in the form of a Global Certificate, the record date for each Interest Payment Date shall be the first day of the month in which such Interest Payment Date occurs (in each
case, the applicable “Record Date”). Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such Record Date, and may be paid to the Person in whose name the
Subordinated Notes is registered at the close of business on a special record date to be fixed by the Trustee for the payment of such defaulted interest after the Company has deposited with the Trustee an amount of money equal to the aggregate
amount proposed to be paid in respect of such defaulted interest, notice whereof shall be given to the registered Holders of this series of Subordinated Notes not less than ten days prior to such special record date, or may be paid at any time in
any other lawful manner not inconsistent with the requirements of any securities exchange on which the Subordinated Notes may be listed, and upon such notice as may be required by such exchange. 

Section 2.5 Effect of Benchmark Transition Event 

(a) Benchmark Replacement. If the Company or its designee determines that a Benchmark Transition Event and its related Benchmark
Replacement Date have occurred prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Subordinated Notes in respect
of such determination on such date and all determinations on all subsequent dates. 

  
 -10- 

 (b) Benchmark Replacement Conforming Changes. In connection with the implementation
of a Benchmark Replacement, the Company or its designee will have the right to make Benchmark Replacement Conforming Changes from time to time without the consent of the Holders of the Subordinated Notes or the Trustee. 

(c) Decisions and Determinations. Any determination, decision or election that may be made by the Company or its designee pursuant to
the Benchmark Transition provisions described herein, including any determination with respect to tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any
decision to take or refrain from taking any action or any selection: 
 (i) will be conclusive and binding absent manifest error; 

(ii) if made by the Company, will be made in the Company’s sole discretion; 

(iii) if made by the Company’s designee, will be made after consultation with the Company, and such designee will not make any such
determination, decision or election to which the Company objects; and 
 (iv) notwithstanding anything to the contrary herein or in the
Subordinated Notes, shall become effective without consent from the Holders of the Subordinated Notes or any other party. 
 (d) Any
determination, decision or election pursuant to the Benchmark Replacement provisions set forth in this Section 2.5 shall be made by the Company or its designee (which may be the Company’s Affiliate) on the basis described above, and in no
event shall the Trustee, any Paying Agent or the Calculation Agent be responsible for making any such determination, decision or election. The Company may, in its sole discretion, designate any Affiliate of the Company or any other person to make
one or more determinations, decisions or elections on a temporary or permanent basis, and the Company may, in its sole discretion, revoke any such designation. Any person so designated in accordance with the immediately preceding sentence will be a
“designee” for purposes of these provisions addressing the effect of a Benchmark Transition Event for so long as such designation remains in effect. 

(e) None of the Trustee, any Paying Agent or the Calculation Agent shall be under any obligation to (i) monitor, determine or verify the
unavailability or cessation of 3-Month LIBOR, or whether or when there has occurred, or to give notice to any other Person of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement
Date, (ii) select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, (iii) select, determine or
designate any Benchmark Replacement Adjustment, or other modifier to any replacement index, or (iv) determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing,
including, but not limited to, adjustments as to any alternative spread thereon, the business day convention, interest determination dates or any other relevant 

  
 -11- 

 
methodology applicable to such substitute or successor Benchmark. In connection with the foregoing, each of the Trustee, any Paying Agent and the Calculation Agent shall be entitled to
conclusively rely on any determinations made by the Company or its designee without independent investigation, and none will have any liability for actions taken at the direction of the Company in connection therewith. 

(f) None of the Trustee, any Paying Agent or the Calculation Agent shall be liable for any inability, failure or delay on its part to perform
any of its duties set forth in this Second Supplemental Subordinated Indenture or the Base Indenture as a result of the unavailability of 3-Month LIBOR or other applicable Benchmark, including as a result of
any failure, inability, delay, error or inaccuracy on the part of any other Person in providing any direction, instruction, notice or information required or contemplated by the terms of this Second Supplemental Indenture or the Base Indenture and
reasonably required for the performance of such duties. None of the Trustee, Paying Agent or Calculation Agent shall be responsible or liable for the actions of the Company or omissions or for those of the Company’s designee, or for any failure
or delay in the performance by the Company or its designee, nor shall any of the Trustee, Paying Agent or Calculation Agent be under any obligation to oversee or monitor the performance of the Company or that of the Company’s designee.

(ii) in whole, but not in part, at any time prior to [•], 2026,6 within 90 days after
the occurrence of a Tax Event or a Regulatory Capital Event at a redemption price equal to the principal amount of the Subordinated Notes being redeemed plus accrued and unpaid interest to but excluding the Redemption Date; or

 (iii) in whole, but not in part, at any time prior to [•], 2026,6 within 90 days after the occurrence of a Rating Agency Event at a redemption price equal to 102% of the principal amount of the Subordinated Notes being redeemed plus accrued and unpaid interest to
but excluding the Redemption Date; 
 provided, in each case, that all accrued and unpaid interest, including deferred interest (and compounded
interest thereon) shall have been paid in full on all Outstanding Subordinated Notes for all Interest Payment Periods ending on or before the Redemption Date. In the event the Subordinated Notes are treated as “Tier 2 Capital” (or a
substantially similar concept) under the capital rules of any Capital Regulator applicable to the Company, any redemption of the Subordinated Notes shall be subject to the Company’s receipt of any required prior approval from such Capital
Regulator and to the satisfaction of any conditions set forth in those capital rules and any other applicable regulations of any other Capital Regulator that are applicable to the Company’s redemption of the Subordinated Notes. 

(b) In no event, shall the Trustee be responsible for monitoring the ratings of the Subordinated Notes or an occurrence of a Rating Agency

 OPTIONAL
DEFERRAL OF INTEREST

elect, at any time and from time to time, to defer the payment of interest on the Subordinated Notes for one or more consecutive Interest Payment Periods that do not exceed five years for any single Deferral Period, provided that no Deferral Period
shall extend beyond the Maturity Date, any earlier accelerated maturity date arising from an Event of Default or any other earlier redemption of the Subordinated Notes. If the Company has paid all deferred interest (including compounded interest
thereon) on the Subordinated Notes, the Company shall have the right to elect to begin a new Deferral Period pursuant to this Section 4.1. 

(b) At the end of any Deferral Period, the Company shall pay all accrued and unpaid deferred interest (including compounded interest thereon)

sixty and no fewer than five days prior to the relevant Interest Payment Date. The Company shall provide a notice to the Trustee of the commencement or continuance of any Deferral Period no more than sixty and no fewer than fifteen days prior to the
relevant Interest Payment Date. Such notice of deferral, once given, will be irrevocable and the deferral of payments on the related Interest Payment Date will be considered a deferral subject to Section 4.1 above. 

ARTICLE V 
 EVENTS OF
DEFAULT 
 Section 5.1 Events of Default. 

(a) Section 5.01 of the Base Indenture shall apply to the Subordinated Notes. 

(b) The Trustee shall provide to the Holders of the Subordinated Notes notice of any Event of Default or default with respect to the
Subordinated Notes within 90 days after the actual knowledge of a Responsible Trust Officer of the Trustee of such Event of Default or default. However, except in the case of a default in payment on the Subordinated Notes, the Trustee will be
protected in withholding the notice if its Responsible Trust Officers determine that withholding of the notice is in the interest of such Holders. 

(c) The Trustee shall have no right or obligation under the Indenture or otherwise to exercise any remedies on behalf of any Holders of the
Subordinated Notes pursuant to the Indenture in connection with any default, unless such remedies are available under the Indenture and the Trustee is directed to exercise such remedies pursuant to and subject to the conditions of Section 5.12
of the Base Indenture, provided, however, that this provision shall not affect the rights of the Trustee with respect to any Events of Default as set forth in Section 5.01 of the Base Indenture that may occur with
respect to the Subordinated Notes. In connection with any such exercise of remedies the Trustee shall be entitled to the same immunities and protections and remedial rights (other than acceleration) as if such default were an Event of Default. 

(d) For purposes of this Section 5.1, the term “default” means any of the following events: 

(i) the failure to pay interest, including compounded interest, in full on any Subordinated Notes for a period of 30 days after the conclusion

(i) declare or pay any dividends or other distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any
shares of Capital Stock of the Company;

redeem any of the Company’s debt securities that rank upon the Company’s liquidation on a parity with or junior to the Subordinated Notes; or

 (A) any purchase, redemption or other acquisition of shares of the Company’s Capital Stock

options or other rights is the same stock as that on which the dividend is being paid or ranks equally with or junior to such stock; or 

(F) (i) any payment of current or deferred interest on Parity Securities that is made pro rata to the amounts
due on such Parity Securities (including the Subordinated Notes) and (ii) any payments of principal or current or deferred interest on Parity Securities that, if not made, would cause the Company to breach the terms of the
instrument governing such Parity Securities. 
 For the avoidance of doubt, notwithstanding anything herein to the contrary, no terms of the
Subordinated Notes will restrict in any manner the ability of any of the Subsidiaries to pay dividends to the Company or any other Subsidiaries or make any distributions to the Company or to any other Subsidiaries. 

Section 6.2 [Reserved.]

 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 _____________________________________________________, or registered assigns, the
principal sum of __________________________ dollars ($____________) on April 20, 2067 (the “Maturity Date”). Notwithstanding the preceding sentence, in the event that the Maturity 

  
 -17- 

 
Date is not a Business Day, then the Maturity Date will be the next succeeding day which is a Business Day, except if such Business Day is in the next succeeding calendar month then the Maturity
Date will be the immediately preceding day which is a Business Day. The Subordinated Notes will bear interest at the per annum rate of 3-Month LIBOR plus a margin equal to 2.0400% (the “Floating
Rate”), payable quarterly on January 20, April 20, July 20 and October 20. Interest payments in respect of Interest Payment Periods will include accrued interest from and including the last date in respect of which interest has
been paid or duly provided for to, but not including, the next succeeding Interest Payment Date or the Maturity Date, as the case may be; provided, however, that the amount of interest payable for the first Interest Payment Period shall be
determined from and including [July 20]7, 2021. The amount of interest payable will be computed on the basis of a 360-day year and the actual number of days
elapsed in each quarterly Interest Payment Period. All percentages resulting from any interest rate calculation will be rounded upward or downward, as appropriate, to the next higher or lower
one-hundred-thousandth of a percentage point. If any Interest Payment Date is not a Business Day, then the Interest Payment Date shall be the immediately succeeding Business Day, except that if such Business
Day is in the next succeeding calendar month then such Interest Payment Date will be the immediately preceding Business Day. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as
provided in the Base Indenture, be paid to the Person in whose name this Subordinated Note is registered at the close of business on the day next preceding the Interest Payment Date; provided, that in the event the Subordinated Notes will not
continue to remain in book-entry form or are not in the form of a Global Certificate, the record date for each Interest Payment Date shall be the first day of the month in which such Interest Payment Date occurs (in each case, the applicable
“Record Date”). Any such interest installment not punctually paid or duly provided for shall forthwith cease to be payable to the registered Holders on such record date, and may be paid to the Person in whose name this Subordinated Note is
registered at the close of business on a special record date to be fixed by the Trustee for the payment of such defaulted interest after the Company has deposited with the Trustee an amount of money equal to the aggregate amount proposed to be paid
in respect of such defaulted interest, notice whereof shall be given to the registered Holders of this series of Subordinated Notes not less than ten days prior to such special record date, or may be paid at any time in any other lawful manner not
inconsistent with the requirements of any securities exchange on which the Subordinated Notes may be listed, and upon such notice as may be required by such exchange, all as more fully provided in the Indenture. The principal of (and premium, if
any) and the interest (including any compounded interest thereon) on this Subordinated Note shall be payable at the office or agency of the Trustee maintained for that purpose in the United States, in any coin or currency of the United States of
America which at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made at the option of the Company by check mailed to the registered Holder at such address as shall
appear in the Security Register. 
  

	7 	 Initial Interest Payment Date and first Interest Payment Period assume that the expiration date (as defined in
the Registration Statement) occurs on August 9, 2021 and the Subordinated Notes are issued on August 11, 2021. In the event that the record date for an interest payment on the capital securities due 2067 occurs prior to the expiration date
and the related interest payment date would occur thereafter, interest will be paid in full for the entire interest period on the scheduled date for such payment (even if occurring after the settlement date (as defined in the Registration
Statement)), as if such capital securities due 2067 had not been exchanged in the exchange offer, to the holders of record of such capital securities as of the close of business on such record date, and the Subordinated Notes will accrue interest
from and including the date to which such interest is paid. 

  
 -18- 

 The Indebtedness evidenced by this Subordinated Note is, to the extent provided in the
Indenture, subordinate and junior in right of payment to the prior payment in full of all Senior Indebtedness, and this Subordinated Note is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Subordinated
Note, 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 action as may be necessary or appropriate to acknowledge or 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, hereby waives all notice of
the acceptance of the subordination provisions contained herein and in the Indenture by each Holder of Senior Indebtedness, 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 Subordinated 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. 
 Unless the certificate of authentication hereon has been executed by
the Trustee referred to on the reverse hereof by manual, facsimile or electronic signature, this Subordinated Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

 [REVERSE OF NOTE] 

This Note is one of a duly authorized issue of securities of the Company (herein called the “Subordinated Notes”), issued and to be
issued in one or more series under a Subordinated Indenture, dated as of ___, 2021 (herein called the “Base Indenture”), between the Company and The Bank of New York Mellon (herein called the “Trustee”, which term includes any
successor trustee under the Indenture), as supplemented by a Second Supplemental Subordinated Indenture, dated as of ___, 2021 (the “Second Supplemental Subordinated Indenture” and the Base Indenture as so supplemented, 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 Subordinated Notes, and of the terms upon which the Subordinated Notes are, and are to be, authenticated and delivered. This Subordinated Note is one of the series designated on the face hereof, limited in aggregate principal amount to
$__________. 
 All terms used in this Subordinated Note that are defined in the Indenture shall have the meanings assigned to them in the
Indenture. 
 The Company shall have the right, at its option, to redeem the Subordinated Notes for cash: 

(a) in whole at any time or in part from time to time on or after [•], 2026,9 at a
redemption price equal to 100% of the principal amount of the Subordinated Notes being redeemed plus accrued and unpaid interest to but excluding the Redemption Date; provided that if the Subordinated Notes are not redeemed in whole, at least
$25 million aggregate principal amount of the Subordinated Notes (excluding any Subordinated Notes held by the Company or any of its Affiliates) remains Outstanding after giving effect to such redemption; 

(b) in whole, but not in part, at any time prior to [•], 2026,9 within 90 days after
the occurrence of a Tax Event or a Regulatory Capital Event, at a redemption price equal to 100% of the principal amount of the Subordinated Notes being redeemed plus accrued and unpaid interest to but excluding the Redemption Date; or 

(c) in whole, but not in part, at any time prior to [•], 2026,9 within 90 days after
the occurrence of a Rating Agency Event, at a redemption price equal to 102% of the principal amount of the Subordinated Notes being redeemed plus accrued and unpaid interest to but excluding the Redemption Date. 

Notwithstanding the foregoing, the Company may not redeem the Subordinated Notes unless all accrued and unpaid interest, including deferred
interest (and compounded interest thereon), has been paid in full on all Outstanding Subordinated Notes for all Interest Payment Periods ending on or before the Redemption Date. 

 

	9 	 The date that is five years after the issuance date of the Subordinated Notes.

  
 -21- 

 The Company will prepare and mail a notice of redemption to each Holder of Subordinated
Notes to be redeemed by first-class mail at least 15 but not more than 60 days prior to the date fixed for redemption. On and after a Redemption Date, interest will cease to accrue on the Subordinated Notes called for redemption (unless the Company
defaults in the payment of the redemption price and accrued interest (including any compounded interest thereon)). On or before a Redemption Date, the Company will deposit with a Paying Agent (or the Trustee) money sufficient to pay the redemption
price of and accrued interest (including any compounded interest thereon) on the Subordinated Notes to be redeemed on that date. If less than all of the Subordinated Notes are to be redeemed, the Subordinated Notes to be redeemed shall be selected
by the Trustee by lot; provided that, to the extent the Subordinated Notes to be redeemed are represented by a Global Certificate, such Subordinated Notes shall be selected in accordance with the procedures of DTC. 

The Subordinated Notes are not entitled to the benefit of any sinking fund. 

If an Event of Default with respect to Subordinated Notes of this series shall occur and be continuing, the principal of the Subordinated
Notes 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 Subordinated Note
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 Subordinated Note shall be conclusive and binding upon such Holder and upon all future Holders of this Subordinated Note and of any Subordinated Note 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 Subordinated Note. 

So long as no Event of Default with respect to this Subordinated Note has occurred or is continuing, the Company shall have the right at any
time during the term of this Subordinated Note to defer payment of interest on this Subordinated Note for one or more consecutive Interest Periods that do not exceed five years for any single Deferral Period, during which 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; provided, however, that no Deferral Period shall extend beyond the Maturity Date or
the earlier accelerated maturity date arising from an Event of Default or redemption of this Subordinated Note. Upon the termination of any Deferral Period and upon the payment of all deferred interest then due, the Company may elect to begin a new
Deferral Period, subject to the above requirements. 

  
 -22- 

 So long as any Subordinated Notes of this series remain outstanding, if the Company has
given notice of its election to defer interest payments on the Subordinated Notes but the related Deferral Period has not yet commenced or a Deferral Period is continuing, the Company shall not, and shall not permit any Subsidiary to,
(i) declare or pay any dividends or other distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any shares of the Company’s Capital Stock, (ii) make any payment of principal of, or interest or
premium, if any, on or repay, purchase or redeem any debt securities of the Company that rank upon the Company’s liquidation on a parity with this Subordinated Note or junior to this Subordinated Note or (iii) make any guarantee payments
regarding any guarantee issued by the Company of securities of any Subsidiary if the guarantee ranks upon the Company’s liquidation on a parity with or junior to this Subordinated Note (other than (a) any purchase, redemption or other
acquisition of shares of its Capital Stock in connection with (1) any employment contract, benefit plan or other similar arrangement with or for the benefit of any one or more of its employees, officers, directors, consultants or independent
contractors, (2) the satisfaction of the Company’s obligations pursuant to any contract entered into prior to the beginning of the applicable Deferral Period, (3) a dividend reinvestment or shareholder purchase plan, or (4) the
issuance of shares of the Company’s Capital Stock, or securities convertible into or exercisable for such shares, as consideration in an acquisition transaction entered into prior to the applicable Deferral Period, (b) any exchange,
redemption or conversion of any class or series of the Company’s Capital Stock, or the Capital Stock of one of its Subsidiaries, for any other class or series of its Capital Stock, or of any class or series of its Indebtedness for any class or
series of its Capital Stock, (c) any purchase of fractional interests in shares of the Company’s Capital Stock pursuant to the conversion or exchange provisions of such shares or the securities being converted or exchanged, (d) any
declaration of a dividend in connection with any shareholder rights plan, or the issuance of rights, stock or other property under any shareholder rights plan, or the redemption or purchase of rights pursuant thereto, (e) any dividend in the
form of stock, warrants, options or other rights where the dividend stock or stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks equally with or junior to such
stock, or (f) (1) any payment of current or deferred interest on Parity Securities that is made pro rata to the amounts due on such Parity Securities (including the Notes), and (2) any payments of principal or current or deferred interest
on Parity Securities that, if not made, would cause the Company to breach the terms of the instrument governing such Parity Securities). 

The Company shall give written notice of its election to commence or continue any Deferral Period to the Trustee and the Holders of all
Securities of this series then Outstanding at least five days (in the case of the Trustee) or fifteen days (in the case of the Holders) and not more than 60 days, in each case, before the next Interest Payment Date. Such notice shall be given to the
Trustee and the Holder of this Security at such Holder’s address appearing in the Security Register by first-class mail, postage prepaid (or, as long as the Notes are held through DTC, transmitted in accordance with applicable procedures of
DTC). 
 Except as provided in the immediately preceding paragraph and Article XI of the Second Supplemental Subordinated Indenture, no
reference herein to the Indenture and no provision of this Subordinated 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 premium, if any) and interest on
this Subordinated Note at the times, place and rate, and in the coin or currency, herein prescribed. 

  
 -23- 

 As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Subordinated Note is registrable in the Securities Register, upon surrender of this Subordinated Note for registration of transfer at the office or agency of the Company maintained under Section 10.2 of the Base 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
Subordinated Notes 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 Subordinated 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 Subordinated Note is registered as the owner hereof for all purposes, whether or not this Subordinated Note be overdue, and neither the Company, the Trustee nor any such agent shall be affected by
notice to the contrary. 
 The Subordinated Notes are issuable only in registered form without coupons in denominations of $2,000 and
integral multiples of $1,000 in excess thereof. This Global Security is exchangeable for Subordinated Notes in definitive form only under certain limited circumstances set forth in the Indenture. Subordinated Notes so issued are issuable only in
registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in excess thereof. As provided in the Base Indenture and subject to certain limitations therein set forth, Subordinated Notes are exchangeable for a like
aggregate principal amount of Subordinated Notes of a different authorized denomination, as requested by the Holder surrendering the same. 

No recourse shall be had for the payment of the principal of or the interest on this Subordinated Note, or for any claim based hereon, or
otherwise in respect hereof, or based on or in respect of the Indenture, against any incorporator, shareholder, officer or director, past, present or future, as such, of the Company or of any predecessor or 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 issuance hereof, expressly waived and released.

 The Company agrees and, by its acceptance of this Subordinated Note or a beneficial interest therein, the Holder of, and any Person that
acquires a beneficial interest in, this Subordinated Note agrees to treat this Subordinated Note as Indebtedness for United States federal, state and local tax purposes. 

THE INDENTURE AND THIS SUBORDINATED NOTE SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO
CONTRACTS MADE AND TO BE PERFORMED ENTIRELY WITHIN SUCH STATE.
