 For and in consideration of the promises and the purchase of the 2028 Senior Notes by
the Holders thereof, it is mutually covenanted and agreed, for the equal and proportionate benefit of all Holders of the 2028 Senior Notes, as follows: 

 Section 1. The Original Indenture is hereby amended solely with
respect to the 2028 Senior Notes as follows: 
  

	 	(A)	 By amending Section 101 to insert the following definitions in their entirety in the appropriate
alphabetical order as follows: 

 “Change of Control” means the occurrence of any one of the following:
(1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of the Company’s and its subsidiaries
assets taken as a whole to any Person other than to the Company or a Subsidiary; (2) the consummation of any transaction (including without limitation, any merger or consolidation) the result of which is that any Person becomes the
“beneficial owner” (as defined in Rules 13d-3 and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the outstanding Voting Stock of
the Company or the Voting Stock of any Parent Company (as defined below) or other Voting Stock into which the Voting Stock of the Company or the Voting Stock of any Parent Company is reclassified, consolidated, exchanged or changed, measured by
voting power rather than number of shares; (3) the Company or any Parent Company consolidates with, or merges with or into, any Person, or any Person consolidates with, or merges with or into, the Company or any Parent Company, in any such
event pursuant to a transaction in which any of the outstanding Voting Stock of the Company, the Voting Stock of such Parent Company or the Voting Stock of such other Person is converted into or exchanged for cash, securities or other property,
other than any such transaction where the shares of the Voting Stock of the Company or the Voting Stock of such Parent Company outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the
Voting Stock of the surviving Person or any Parent Company of the surviving Person immediately after giving effect to such transaction; or (4) the adoption of a plan relating to the liquidation or dissolution of the Company. Notwithstanding the
foregoing, a transaction will not be deemed to involve a Change of Control under clause (2) above if (i) the Company becomes a subsidiary of a Parent Company and (ii) the holders of the Voting Stock of the Company or the Voting Stock
of any Parent Company immediately prior to such transaction hold at least a majority of the Voting Stock of such Parent Company immediately following such transaction; provided that any series of related transactions shall be treated as a single
transaction. The term “Person,” solely as used in this definition, has the meaning given thereto in Section 13(d)(3) of the Exchange Act. 

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a related Rating Event. 

“Common Stock” means, with respect to any Principal Subsidiary, Capital Stock of any class, however designated, except Capital Stock
which is non-participating beyond fixed dividend and liquidation preferences and the holders of which have either no voting rights or limited voting rights entitling them, only in the case of certain
contingencies, to elect less than a majority of the directors (or persons performing similar functions) of such Principal Subsidiary, and also includes securities of any class, however designated, which are convertible into Common Stock. 

  
 2 

 “Electronic Means” means the following communications methods: e-mail, facsimile transmission, secure electronic transmission containing applicable authorization codes, passwords and/or authentication keys issued by the Trustee, or another method or system specified by the
Trustee as available for use in connection with its services hereunder. 
 “Indebtedness” means, with respect to any Person
(without duplication): 
 (1) any liability of that Person (A) for borrowed money, or under any reimbursement obligation relating to a
letter of credit or similar instrument; (B) evidenced by a bond, note, debenture or similar instrument; (C) to pay the deferred purchase price of property or services, except trade accounts payable arising in the ordinary course of
business; or (D) for the payment of money relating to any obligations under any capital lease of real or personal property which has been recorded as a capitalized lease obligation; 

(2) any liability of others described in the preceding clause (1) that the Person has guaranteed or that is otherwise its legal liability
or which is secured by a lien on that Person’s Property; and 
 (3) any amendment, supplement, modification, deferral, renewal,
extension or refunding of any liability of the types referred to in clauses (1) or (2) above. 
 “Investment Grade” means a
rating of Baa3 or better by Moody’s (or its equivalent under any successor rating category) and a rating of BBB- or better by S&P Global Ratings (or its equivalent under any successor rating
category). 
 “Issue Date” means the first date on which 2028 Senior Notes are issued, which shall be November 22, 2022. 

“Moody’s” means Moody’s Investors Service, Inc., or any successor thereto. 

“Parent Company” means any holding company that, directly or indirectly, owns 100% of the Voting Stock of the Company. 

“Principal Subsidiary” means a consolidated subsidiary of the Company that, as of the relevant time of determination, is a
“significant subsidiary” as defined under Rule 405 under the Securities Act of 1933, as amended (as that Rule is in effect on November 7, 2022, without giving effect to any further amendment of that Rule). 

“Rating Agency” means: 

  
 3 

 (1) each of Moody’s and S&P Global Ratings, and 

(2) if either or both of Moody’s or S&P Global Ratings ceases to rate the 2028 Senior Notes or fails to make a rating of the 2028
Senior Notes publicly available for reasons outside of the Company’s control, a Substitute Rating Agency in lieu thereof. 

“Rating Event” means (i) the rating of the 2028 Senior Notes is lowered by both Rating Agencies during the related Trigger
Period and (ii) the 2028 Senior Notes are rated below an Investment Grade rating by both Rating Agencies on any day during such Trigger Period. If either Rating Agency is not providing a rating of the 2028 Senior Notes on any day during such
Trigger Period for any reason, the rating of such Rating Agency shall be deemed to be below Investment Grade on such day and such Rating Agency will be deemed to have lowered its rating of the 2028 Senior Notes during the Trigger Period. For the
avoidance of doubt, the Trustee shall not be charged with knowledge of any Rating Event nor have any duty to monitor the ratings of the Securities. 

“S&P Global Ratings” means S&P Global Ratings, a division of S&P Global Inc. 

“Substitute Rating Agency” means a “nationally recognized statistical rating organization” as that term is defined in
Section 3(a)(62) of the Exchange Act, selected by the Company (as certified by a resolution of the Board of Directors delivered to the Trustee) as a replacement agency for Moody’s or S&P Global Ratings, or both of them, as the case may
be. 
 “Trigger Period” means the period commencing on the earlier of the first public notice of (a) the occurrence of a
Change of Control or (b) the Company’s intention to effect a Change of Control and ending 60 days following consummation of such Change of Control (which period shall be extended so long as the rating of the 2028 Senior Notes is under
publicly announced consideration for a possible downgrade by either of the Rating Agencies). 
 “Voting Stock” means, with respect
to any Person as of any date, the Capital Stock of such Person that is at the time entitled to vote generally in the election of the board of directors (or other analogous managing body) of such Person.

	 	(D)	 By replacing the sixth paragraph of Section 303 of the Original Indenture in its entirety as follows:

valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee, either by manual, facsimile or electronic execution, for such Security
or on its behalf pursuant to Section 614, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder.

“Covenant Defeasance”), and the 2028 Senior Notes and any coupons appertaining thereto shall thereafter be deemed not “Outstanding” for the purposes of any direction, waiver, consent or declaration or act of Holders (and the
consequences of any thereof) in connection with such covenants, but shall continue to be deemed “Outstanding” for all other purposes hereunder (it being understood that such 2028 Senior Notes shall not be deemed outstanding for accounting
purposes). For this purpose, such Covenant Defeasance means that, with respect to the Outstanding 2028 Senior Notes and any coupons appertaining thereto, the Company may omit to comply with and shall have no liability in respect of any term,
condition or limitation set forth in any such covenant, whether directly or indirectly, by reason of any reference elsewhere herein to any such covenant or by reason of any reference in any such covenant to any other provision herein or in any other

 (c) The Company shall not be required to
make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the Company and the

 10

Supplemental Indenture as fully and with like effect as if set forth herein in full. 
 Section 3. As supplemented
hereby, the Original Indenture is in all respects ratified and confirmed, and the Original Indenture and this Twenty-Second Supplemental Indenture shall be read, taken and construed as one and the same instrument and all references to Securities in
the Original Indenture shall be deemed to refer also to the 2028 Senior Notes unless the context otherwise provides. 

Section 4. This Twenty-Second Supplemental Indenture shall be governed by, and construed in accordance with, the
laws of the State of New York. 
 Section 5. In the event of a conflict between the terms and conditions of the
Original Indenture and the terms and conditions of this Twenty-Second Supplemental Indenture, then the terms and conditions of this Twenty-Second Supplemental Indenture shall prevail; provided that if and to the extent that any provision of this
Twenty-Second Supplemental Indenture limits, qualifies or conflicts with another provision which is required to be included herein or in the Original Indenture by the Trust Indenture Act of 1939, as amended, such required provision shall control.

 Section 6. All covenants and agreements in this Twenty-Second Supplemental Indenture by the Company shall bind
its successors and assigns, whether so expressed or not.

Supplemental Indenture shall be invalid, illegal or unenforceable, the validity, legality and enforceability of the remaining provisions shall not in any way be affected or impaired hereby.

equitable right, remedy or claim under this Twenty-Second Supplemental Indenture.

 Section 9. This Twenty-Second Supplemental Indenture may be
simultaneously executed in several counterparts, each of which shall be deemed to be an original, and such counterparts shall together constitute but one and the same instrument. The words “execution,” signed,” “signature,”
and words of like import in this Supplemental Indenture or in any other certificate, agreement or document related to this Supplemental Indenture shall include images of manually executed signatures transmitted by facsimile or other electronic
format (including, without limitation, “pdf”, “tif” or “jpg”) and other electronic signatures (including, without limitation, DocuSign and AdobeSign). The use of electronic signatures and electronic records (including,
without limitation, any contract or other record created, generated, sent, communicated, received, or stored by electronic means) shall be of the same legal effect, validity and enforceability as a manually executed signature or use of a paper-based
record-keeping system to the fullest extent permitted by applicable law, including the Federal Electronic Signatures in Global and National Commerce Act, the New York State Electronic Signatures and Records Act and any other applicable law,
including, without limitation, any state law based on the Uniform Electronic Transactions Act or the Uniform Commercial Code.

instructions (for the purposes of this Section, “Instructions”) given pursuant to the Indenture and delivered using Electronic Means; provided, however, that the Company shall provide to the Trustee an incumbency certificate listing
authorized officers and containing specimen signatures of such authorized officers, which incumbency certificate shall be amended by the Company whenever a person is to be added or deleted from the listing. If the Company elects to give the Trustee

 (Reverse of Note) 

HUMANA INC. 
 This Note is one of
a duly authorized issue of Securities of the Company designated as its 5.750% Senior Notes due 2028 (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 a twenty-second supplemental indenture, dated as of November 22, 2022 (the
“Twenty-Second Supplemental Indenture”; the Base Indenture as supplemented by the Twenty-Second 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 $500,000,000. 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 Securities) 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. 

 Prior to February 1, 2028 (1 month prior to their maturity date) (the “Par Call
Date”), the Company may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a Redemption Price (expressed as a percentage of principal amount and rounded to three decimal places) equal to the greater of:

 (1) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption
Date (assuming the Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the Treasury Rate plus 25
basis points less (b) interest accrued to the date of redemption, and 
 (2) 100% of the principal amount of the notes to be redeemed,

 plus, in either case, accrued and unpaid interest thereon to the Redemption Date. 

On or after the Par Call Date, the Company may redeem the notes, 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 being redeemed plus accrued and unpaid interest thereon to the Redemption Date. 

“Treasury Rate” means, with respect to any Redemption Date, the yield determined by the Company in accordance with the following two
paragraphs. 
 The Treasury Rate shall be determined by the Company after 4:15 p.m., New York City time (or after such time as yields on
U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third business day preceding the Redemption Date based upon the yield or yields for the most recent day that appear after such time on such
day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication) (“H.15”) under the
caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading). In determining the Treasury Rate, the Company shall select, as applicable: (1) the yield for the Treasury
constant maturity on H.15 exactly equal to the period from the Redemption Date to the Par Call Date (the “Remaining Life”); or (2) if there is no such Treasury constant maturity on H.15 exactly equal to the Remaining Life, the two
yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15 immediately longer than the Remaining Life – and shall interpolate to
the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (3) if there is no such Treasury constant maturity on H.15 shorter than or longer than the
Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant maturity or maturities on H.15 shall be deemed to have a maturity date equal
to the relevant number of months or years, as applicable, of such Treasury constant maturity from the Redemption Date. 

 If on the third business day preceding the Redemption Date H.15 or any successor designation
or publication is no longer published, the Company shall calculate the Treasury Rate based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second business day preceding such
Redemption Date of the United States Treasury security maturing on, or with a maturity that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more
United States Treasury securities with a maturity date equally distant from the Par Call Date, one with a maturity date preceding the Par Call Date, and one with a maturity date following the Par Call Date, the Company shall select the United States
Treasury security with a maturity date preceding the Par Call Date. If there are two or more United States Treasury securities maturing on the Par Call Date, or two or more United States Treasury securities meeting the criteria of the preceding
sentence, the Company shall select from among these two or more United States Treasury securities the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury
securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the
bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury security, and rounded to three decimal places. 

The Company’s actions and determinations in determining the Redemption Price shall be conclusive and binding for all purposes, absent
manifest error. The Trustee shall have no responsibility for the calculation of the Redemption Price. 
 Notice of any redemption will be
mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the Redemption Date to each Holder of the Notes to be redeemed. 

In the case of a partial redemption, selection of the Notes for redemption will be made, in the case of Global Securities, in accordance with
the Depositary’s procedures, and in the case of definitive Securities, by lot or by such other method as the Trustee deems appropriate. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in
part only, the notice of redemption that relates to the note will state the portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the
Holder of the note upon surrender for cancellation of the original Note. For so long as the Notes are held by Depository Trust Company (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures
of the Depositary. 
 Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease
to accrue on the notes or portions thereof called for redemption. 
 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 aggregate 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; (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 aggregate 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.
