4.500% SENIOR NOTES DUE 2049 

UNUM GROUP, a corporation duly organized and existing under the laws of the State of Delaware (the “Company”, which term includes
any successor Person under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., as nominee of The Depository Trust Company, or registered assigns, the principal sum of FOUR HUNDRED AND FIFTY
MILLION DOLLARS ($450,000,000) on December 15, 2049 (such date is hereinafter referred to as the “Stated Maturity”), and to pay interest thereon, from September 11, 2019, or from the most recent Interest Payment Date (as defined
below) for which interest has been paid or duly provided for, at the rate of 4.500% per annum (the “Interest Rate”). Interest on this Note shall be payable semi-annually in arrears on June 15 and December 15 of each year
(each, an “Interest Payment Date”), commencing December 15, 2019, until the principal hereof is paid or made available for payment. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will,
as provided in the Indenture, be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest, which shall be the June 1 or
December 1, as the case may be (whether or not a Business Day) immediately preceding such Interest Payment Date; provided, 











 
that interest payable at the Stated Maturity or on a Redemption Date will be paid to the Person to whom principal is payable on such date. Any such interest not so punctually paid or duly
provided for will forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Note (or one or more Predecessor Securities) is registered at the close of business on a Special Record
Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice of which shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date and shall otherwise be payable, all as more
fully provided in the Indenture. 
 Payments of principal and premium, if any, shall be made upon the surrender of this Note at the
Corporate Trust Office of the Trustee, or at such other office or agency of the Company as may be designated by the Company for such purpose in the Borough of Manhattan, The City of New York or in the City of Chattanooga, Tennessee, in such coin or
currency of the United States of America as at the time of payment shall be legal tender for the payment of public and private debts, by Dollar check drawn on, or transfer to, a Dollar account. Payments of interest on this Note may be made by Dollar
check, drawn on a Dollar account, mailed to the address of the Person entitled thereto as such address shall appear in the Security Register, or, upon written application by the Holder to the Security Registrar setting forth wire instructions not
later than the relevant Regular Record Date, by wire transfer to a Dollar account. The amount of interest payable for any period on any Interest Payment Date shall be computed on the basis of a 360-day year
consisting of twelve 30-day months. In the event that any date on which interest is payable on the Notes is not a Business Day, then payment of interest payable on such date will be made on the next succeeding
day which is a Business Day (and without any interest or other payment in respect of any such delay). 
 Reference is hereby made to the
further provisions of this Note set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if fully set forth at this place. 

Unless the certificate of authorization hereon has been executed by the Trustee referred to on the reverse hereof or an Authentication Agent
by the manual signature of one of their respective authorized signatories, this Note shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose. 











 IN WITNESS WHEREOF, the Company has caused this Note to be executed and delivered.

 CERTIFICATE OF AUTHENTICATION 

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture. 

Dated: September 11, 2019 
  

			
	THE BANK OF NEW YORK MELLON TRUST COMPANY, N.A., as Trustee
		
	By:	 	  

		 	Authorized Signatory













 This Note is one of a duly authorized issue of securities of the Company designated as its
“4.500% Senior Notes due 2049” (herein sometimes referred to as the “Notes”), issued and to be issued under and pursuant to an Indenture, dated as of August 23, 2012 (the “Indenture”), duly executed and delivered
between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations
of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Notes and of the terms upon which the Notes are, and are to be, authenticated and delivered. 

This Note is one of the series designated herein, initially limited to a principal amount of $450,000,000, which amount may be increased at
the option of the Company if in the future it determines that it may wish to sell additional Securities of this series. References herein to “this series” mean the series designated herein. 

The Notes 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 Indenture and subject to certain limitations therein set forth, Notes so issued are exchangeable for a like aggregate principal amount of Notes of a different authorized denomination, as requested by the Holder surrendering the
same. 
 No sinking fund is provided for the Notes. 

The Notes shall be redeemable in whole at any time or in part from time to time prior to June 15, 2049, at the Company’s option, at
a Redemption Price equal to the greater of (i) 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the principal amount to be redeemed to the Redemption Date and (ii) the sum, as calculated by the
Independent Investment Banker, of the present values of the remaining scheduled payments of principal and interest (exclusive of interest accrued to the Redemption Date) on the Notes to be redeemed (assuming for such purpose that the Notes mature on
June 15, 2049) discounted to the Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the then current Treasury
Rate plus 30 basis points, plus accrued and unpaid interest on the principal amount to be redeemed to the Redemption Date. On or after June 15, 2049, the Company shall have the right to redeem the Notes, at the Company’s option in whole or
in part, at any time and from time to time at a Redemption Price equal to 100% of the principal amount of the Notes to be redeemed, plus accrued and unpaid interest on the principal amount to be redeemed to the Redemption Date. 

For the purposes of the foregoing, the following definitions shall apply: 

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a
maturity comparable to the remaining term (“Remaining Life”) of the Notes to be redeemed (assuming for such purpose that the Notes mature on June 15, 2049) that would be utilized, at the time of selection and in accordance with
customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of such Notes (assuming for such purpose that the Notes mature on June 15, 2049). 

“Comparable Treasury Price” means, with respect to any Redemption Date, the average of the Reference Treasury Dealer Quotations for
such Redemption Date. 











 “Independent Investment Banker” means any of (1) BofA Securities, Inc.,
(2) Goldman Sachs & Co. LLC, (3) HSBC Securities (USA) Inc. and (4) Wells Fargo Securities, LLC, and their respective successors, as selected by the Company, or, if any such firm or the successors, if any, to such firm, as
the case may be, are unwilling or unable to serve as such, an independent investment banking institution of national standing appointed by the Company. 

“Reference Treasury Dealer” means each of (1) BofA Securities, Inc., (2) Goldman Sachs & Co. LLC, (3) HSBC
Securities (USA) Inc. and (4) Wells Fargo Securities, LLC, and their respective successors; provided, however, that if any of them ceases to be a primary U.S. Government securities dealer (each a “Primary Treasury Dealer”), the
Company will substitute another Primary Treasury Dealer. 
 “Reference Treasury Dealer Quotations” means, with respect to each
Reference Treasury Dealer and any Redemption Date, the average, as determined by the Independent Investment Banker, of the bid and ask prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted
in writing to the Independent Investment Banker by such Reference Treasury Dealer at 5:00 p.m., New York City time, on the third Business Day preceding such Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, the rate per year equal to: 

(1) the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published
statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded United States Treasury securities
adjusted to constant maturity under the caption “Treasury Constant Maturities,” for the maturity corresponding to the Comparable Treasury Issue; provided that, if no maturity is within three months before or after the Remaining Life of the
Notes to be redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from those yields on a straight line basis,
rounding to the nearest month; or 
 (2) if such release (or any successor release) is not published during the week preceding the
calculation date or does not contain such yields, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated using a price for the Comparable Treasury Issue (expressed as a percentage of its
principal amount) equal to the Comparable Treasury Price for such Redemption Date. 
 The Treasury Rate will be calculated on the third
Business Day preceding the Redemption Date. As used in the immediately preceding sentence and in the definition of “Reference Treasury Dealer Quotations” above, the term “Business Day” means any day that is not a Saturday, Sunday
or other day on which commercial banks in New York City are authorized or required by law to remain closed. 
 Notice of any redemption
shall be mailed at least 15 but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed at its registered address. The notice of redemption for the Notes will state, among other things, the amount of Notes to be
redeemed, the Redemption Date, the manner of calculation of the Redemption Price and the place or places that payment will be made upon presentation and surrender of Notes to be redeemed. If less than












 
all of the Notes are to be redeemed at the Company’s option, the Trustee will select, in a manner it deems fair and appropriate, the Notes, or portions of the Notes, to be redeemed. Unless
the Company defaults in the payment of the Redemption Price, interest will cease to accrue on any Notes that have been called for redemption at the Redemption Date. 

The Company will not be required (i) to issue, register the transfer of or exchange any Notes during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of Notes selected for redemption and ending at the close of business on the day of such mailing, or (ii) to register the transfer of or exchange any Notes so selected for
redemption in whole or in part, except the unredeemed portion of any such Notes being redeemed in part. 
 In case an Event of Default shall
occur and be continuing, the principal of all of the Notes, together with accrued interest to the date of declaration, may be declared due and payable in the manner and with the effect provided in the Indenture. 

“Event of Default” means any one of the events (whatever the reason for such Event of Default and whether or not it shall be
voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or governmental body) set forth in Section 501 of the Indenture,
provided, however, that the Events of Default set forth in Section 501(5) of the Indenture shall mean any of the following events: 

Default under a bond, debenture, note, mortgage, indenture or instrument under which there may be issued or by which there may be secured or
evidenced any indebtedness for money borrowed by the Company (or by any Subsidiary, the repayment of which the Company has guaranteed or for which the Company is directly responsible or liable as obligor or guarantor), having a principal amount
outstanding in excess of $50,000,000 (other than indebtedness which is non-recourse to the Company or the Subsidiaries), whether such indebtedness now exists or shall hereafter be created, which default shall
have resulted in such indebtedness being declared due and payable prior to the date on which it would otherwise have become due and payable, without such indebtedness having been discharged, or such acceleration having been rescinded or annulled,
within a period of 30 days after there shall have been given, by registered or certified mail, to the Company by the Trustee or to the Company and the Trustee by the Holders of at least 25% in principal amount of the Outstanding Notes a written
notice specifying such default and requiring the Company to cause such indebtedness to be discharged or cause such acceleration to be rescinded or annulled and stating that such notice is a “Notice of Default” under the Indenture. 

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations
of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the written consent of the Holders of not less than a majority in principal amount of
the Securities at the time Outstanding and affected thereby. The Indenture also contains provisions permitting the Holders of specified percentages in principal amount of the Notes at the time Outstanding, on behalf of the Holders of all the Notes,
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 Note shall be conclusive and binding upon such Holder
and upon all future Holders of this Note and of any Note issued in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note or such other Note. 











 As provided in and subject to the provisions of the Indenture, the Holder of this Note shall
not have the right to institute any proceeding with respect to the Indenture or for the appointment of a receiver or trustee or for any other remedy thereunder, unless (i) such Holder shall have previously given the Trustee written notice of a
continuing Event of Default, (ii) the Holders of not less than 25% in principal amount of the Notes that are Outstanding shall have made a written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee indemnity satisfactory to it, (iii) the Trustee shall not have received from the Holders of a majority in principal amount of the Notes that are Outstanding a direction inconsistent with such request, and (iv) the
Trustee shall have failed to institute any such proceeding for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by any Holder of this Note for the enforcement of any payment
of principal hereof, or any premium of interest hereon on or after the respective due dates expressed herein. 
 No reference herein to the
Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, premium, if any, and interest on this Note at the times, places and rate,
and in the coin or currency, herein prescribed. 
 As provided in the Indenture and subject to certain limitations therein set forth, the
transfer of this Note is registrable on the Security Register upon surrender of this Note for registration of transfer at the Corporate Trust Office of the Trustee or at such other office or agency of the Company as may be designated by it for such
purpose in the Borough of Manhattan, The City of New York or the City of Chattanooga, Tennessee (which shall initially be an office or agency of the Trustee), or at such other offices or agencies as the Company may designate, duly endorsed by, or
accompanied by a written instrument of transfer in form satisfactory to the Security Registrar duly executed by, the Holder thereof or his attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for
the same aggregate principal amount, will be issued to the designated transferee or transferees by the Security Registrar. 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 recover any tax or other governmental charge payable in connection therewith. 
 Prior to due presentation of this 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 Note is registered, as the owner thereof for all purposes, whether or not such Note be overdue, and neither
the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 No recourse for the payment of the principal
(and premium, if any) or interest on this Note and no recourse under or upon any obligation, covenant or agreement of the Company in the Indenture or any indenture supplemental thereto or in any Note, or because of the creation of any indebtedness
represented thereby, shall be had against any incorporator, stockholder, employee, agent, officer or director or subsidiary, as such, past, present or future, of the Company or of any successor corporation, either directly or through the Company or
any 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 consideration for the issue
hereof, expressly waived and released.

OF THE STATE OF NEW YORK. 
 All capitalized terms used in this Note which are defined in the Indenture and are not otherwise defined herein
