 (Reverse of Note) 

HUMANA INC. 
 This Note is one
of a duly authorized issue of Securities of the Company designated as its 4.800% Senior Notes due 2047 (the “Notes”). The Notes are one of an indefinite number of series of debt securities of the Company (the “Securities”),
issued or issuable under and pursuant to a base indenture, dated as of August 5, 2003 (the “Base Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Bank of New York Trust
Company, N.A.) (as successor to The Bank of New York) (herein called the “Trustee,” which term includes any successor Trustee under the Indenture), as supplemented by an eleventh supplemental indenture, dated as of March 16, 2017 (the
“Eleventh Supplemental Indenture”; the Base Indenture as supplemented by the Eleventh Supplemental Indenture is herein called the “Indenture”), to which Indenture and all indentures supplemental thereto (other than supplemental
indentures creating a different series of notes) reference is hereby made for a statement of the respective rights thereunder of the Company, the Trustee and the Holders of the Notes and the terms upon which the Notes are to be authenticated and
delivered. The terms, conditions and provisions of the Notes are those stated in the Indenture, those made part of the Indenture by reference to the Trust Indenture Act of 1939, as amended, and those set forth in this Note. This Note is one of a
series designated on the face hereof initially issued in an aggregate principal amount of $400,000,000. The Company may, from time to time, without the consent of the Holders, issue and sell additional Securities ranking equally with the Notes and
otherwise identical in all respects (except for their date of issue, issue price and, if applicable, the first payment of interest on the additional notes) so that such additional Securities shall be consolidated and form a single series with the
Notes. If any additional Securities are not fungible with the Notes for U.S. federal income tax purposes, they will be issued with a different CUSIP number (or other applicable identifying number). 

The terms of other series of Securities issued under the Base Indenture may vary with respect to interest rates or interest rate formulas,
issue dates, maturity, redemption, repayment, currency of payment and otherwise as provided in the Base Indenture. The Base Indenture further provides that Securities of a single series may be issued at various times, with different maturity dates
and may bear interest at different rates. All terms used in this Note which are defined in the Indenture shall have the meanings assigned to them in the Indenture. 

This Note is not subject to any sinking fund. 

If an Event of Default (other than an Event of Default described in Section 501(5) or 501(6) of the Indenture, with respect to the
Company) with respect to the Notes shall occur and be continuing, then either the Trustee or the Holders of not less than 25% in aggregate principal amount of the Notes of this series then Outstanding may declare the aggregate principal amount of
the Notes of this series due and payable in the manner and with the effect provided in the Indenture. If an Event of Default specified in Section 501(5) or 501(6) occurs with respect to the Company, all of the unpaid principal amount and
accrued interest thereon shall ipso facto become and be immediately due and payable in the manner and with the effect provided in the Indenture without any declaration or other act by the Trustee or any Holder. 







 This Note may be redeemed at any time in whole, or from time to time in part, at the option of
the Company (such date of redemption, the “Optional Redemption Date”) at the Redemption Price (as defined below) plus accrued and unpaid interest thereon to the Optional Redemption Date, subject to the rights of Holders as of the close of
business on a relevant Record Date to receive interest due on the related Interest Payment Date. 
 The “Redemption Price” shall
equal the greater of: 
  

	 	•	 	100% of the principal amount of the Notes to be redeemed; and 

  

	 	•	 	the sum of the present values of the remaining scheduled payments on the Notes to be redeemed consisting of principal and interest, exclusive of interest accrued to the Optional Redemption Date that would be due if the
notes matured on the Par Call Date, discounted to the Optional Redemption Date on a semiannual basis (assuming a 360-day year consisting of twelve 30-day months) at the
applicable Treasury Yield plus 25 basis points; 

 provided, however, that if the Company redeems any Notes on or
after the Par Call Date, the Redemption Price for such Notes shall equal 100% of the principal amount of Notes to be redeemed. 
 The Notes
called for redemption become due on the Optional Redemption Date. Notices of redemption will be mailed (or otherwise transmitted in accordance with the applicable procedures of the Depositary) at least 30 but not more than 60 days before the
Optional Redemption Date to each Holder of Notes to be redeemed at its registered address. The notice of redemption for the Notes will state the amount to be redeemed. On and after the Optional Redemption Date, interest will cease to accrue on any
Notes that are redeemed. If less than all the Notes are redeemed at any time, the Notes shall be selected on a pro rata basis or by any other method the Trustee deems fair and appropriate. 

For purposes of determining the Redemption Price, the following definitions are applicable: 

“Comparable Treasury Issue” means the United States Treasury security selected by an Independent Investment Banker as having a
maturity comparable to the remaining term of the Notes to be redeemed (assuming, for this purpose, that such Notes matured on the Par Call Date) 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 the Notes assuming for this purpose, the Notes mature on the Par Call Date. 

“Comparable Treasury Price” means, with respect to any Optional Redemption Date the average of the Reference Treasury Dealer
Quotations obtained by the Company for that Optional Redemption Date, after excluding the highest and lowest of such Reference Treasury Dealer Quotations, or, if the Company is unable to obtain at least four such Reference Treasury Dealer
Quotations, the average of all Reference Treasury Dealer Quotations obtained by the Company. 







 “Independent Investment Banker” means each of J.P. Morgan Securities LLC, Merrill
Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. LLC or U.S. Bancorp Investments, Inc., as selected by the Company or, if all such firms are unwilling or unable to select the applicable Comparable Treasury Issue, an
independent investment banking institution of national standing appointed by the Company. 
 “Par Call Date” means
September 15, 2046 (6 months prior to maturity). 
 “Reference Treasury Dealer” means each of J.P. Morgan Securities LLC,
Merrill Lynch, Pierce, Fenner & Smith Incorporated, Morgan Stanley & Co. LLC or a treasury dealer selected by U.S. Bancorp Investments, Inc. and their respective successors and two other primary U.S. government securities dealers
in New York City (each, a “Primary Treasury Dealer”) selected by the Independent Investment Banker; provided, however, that if any of the foregoing shall cease to be a Primary Treasury Dealer, the Company shall substitute
therefor another Primary Treasury Dealer. 
 “Reference Treasury Dealer Quotations” means, with respect to each Reference
Treasury Dealer and any Optional Redemption Date for the Notes, an average, as determined by the Company, of the bid and asked prices for the Comparable Treasury Issue for the Notes, expressed in each case as a percentage of its principal amount,
quoted in writing to the Company by the Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding the Optional Redemption Date. 

“Treasury Yield” means, with respect to any Optional Redemption Date, the rate per annum equal to the semi-annual equivalent yield
to maturity, computed as of the third business day immediately preceding the Optional Redemption Date, of the Comparable Treasury Issue, assuming a price for the Comparable Treasury Issue, expressed as a percentage of its principal amount, equal to
the applicable Comparable Treasury Price for the Optional Redemption Date. 
 As provided in the Indenture, the Notes shall be subject to
repurchase by the Company or a third party at the option of the Holders at a purchase price of 101% upon the occurrence of a Change of Control Triggering Event. Upon receipt of notice of a Change of Control Offer, Holders electing to have Notes
repurchased pursuant to the Change of Control Offer shall either (i) surrender this Note with the form of “Option of Holder to Elect Repurchase” attached hereto completed or (ii) transfer its Notes to the Paying Agent by
book-entry transfer pursuant to the applicable procedures of the Paying Agent, in either case prior to the close of business on the third Business Day prior to the Change of Control Payment Date. 

The Indenture permits, with certain exceptions as therein provided, the Company and the Trustee with the consent of the Holders of more than
50% in principal amount of the Securities at the time Outstanding of each series issued under the Indenture to be affected thereby, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series; provided, however, that no such supplemental indenture shall, among other things, (i) change the
Stated Maturity of the principal of, or any installment of principal of or interest on, any Security, or reduce the principal 







 
amount thereof or interest thereon, if any, or any premium payable upon redemption thereof; or (ii) change the Place of Payment on any Security or the currency or currency unit in which any
Security or the principal or interest thereon is payable; (iii) impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity thereof; (iv) reduce or alter the method of computation of any
amount payable upon redemption, repayment or purchase of any Securities by the Company (or the time when such redemption, repayment or purchase may be made); or (v) reduce the percentage in principal amount of the Securities, the Holders of
which are required to consent to any supplemental indenture, without the consent of the Holder of each Security affected thereby. The Indenture also contains provisions permitting the Holders of more than 50% in principal amount of the Securities of
each series at the time outstanding, on behalf of the Holders of all the Securities of that series, to waive compliance by the Company with certain provisions of the Indenture and certain past defaults under the Indenture and their consequences with
respect to such series, except a default in the payment of principal of or interest, if any, on any Security of that series or a default with respect to a covenant or provision of the Indenture which cannot be amended without the consent of such
Holder. 
 The Notes are issuable only in registered form without coupons in denominations of $2,000 and integral multiples of $1,000 in
excess thereof. The Notes shall be initially issued in the form of a Global Security. All payments of principal of (and premium, if any) and interest on the Notes will be made to the Trustee so long as the Notes are in the form of a Global Security.
As provided in the Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes as requested by the Holder surrendering the same. If (x) the Depositary is at any time
unwilling or unable to continue as depository and a successor depository is not appointed by the Company within 90 days after the Company receives such notice or becomes aware of such ineligibility, (y) the Company delivers to the Trustee a
Company Order to the effect that this Note shall be exchangeable or (z) an Event of Default has occurred and is continuing with respect to the Notes, this Note shall be exchangeable for Notes in definitive form and in an equal aggregate
principal amount. Such definitive Notes shall be registered in such name or names as the Depositary shall instruct the Trustee. 
 As
provided in the Indenture and subject to certain limitations set forth therein and above, the transfer of this Note may be registered on the Security Register of the Company, upon surrender of this Note for registration of transfer at the office or
agency of the Company in the Borough of Manhattan, The City of New York, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company duly executed by, the Holder hereof or by 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. 

No reference herein to the Indenture and no provisions of this Note or of the Indenture shall alter or impair the obligation of the Company,
which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Note at the time, place and rate, and in the coin or currency, herein and in the Indenture prescribed. 







 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 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 hereof for all purposes, whether or not this Note
be overdue, and neither the Company, the Trustee nor any such agent shall be affected by notice to the contrary. 
 Certain of the
Company’s obligations under the Indenture with respect to Notes may be terminated if the Company irrevocably deposits with the Trustee money or Government Obligations sufficient to pay and discharge the entire indebtedness on all Notes, as
provided in the Indenture. 
 No recourse shall be had for the payment of the principal of (and premium, if any), or the interest, if any,
on this Note, or for any claim based thereon, or upon any obligation, covenant or agreement of the Company in the Indenture, against any incorporator, stockholder, officer or director, as such, past, present or future, of the Company or of any
successor corporation, whether by virtue of any constitution, statute or rule of law or by the enforcement of any assessment of penalty or otherwise; and all such personal liability is expressly released and waived as a condition of, and as part of
the consideration for, the issuance of this Note. 
 The Indenture and the Notes shall be governed by and construed in accordance with the
laws of the State of New York.
