Pursuant to the Indenture, dated as of February 4, 2008 (the “Indenture”), between UnitedHealth Group Incorporated, a Delaware corporation (the “Company”), and U.S. Bank Trust Company, National Association, as trustee (the “Trustee”), and resolutions adopted by the Company’s Board of Directors on February 24, 2023, this Officers’ Certificate and Company Order is being delivered to the Trustee to establish the terms of a series of Securities in accordance with Section 301 of the Indenture, to establish the form of the Securities of such series in accordance with Section 201 of the Indenture, to request the authentication and delivery of the Securities of such series pursuant to Section 303 of the Indenture and to comply with the provisions of Section 102 of the Indenture. This Officers’ Certificate and Company Order shall be treated for all purposes under the Indenture as a supplemental indenture thereto.

All conditions precedent provided for in the Indenture relating to (i) the establishment of a series of Securities, (ii) the establishment of the form of Securities of such series and (iii) the procedures for authentication and delivery of such series of Securities have been complied with.

Capitalized terms used herein and not otherwise defined herein shall have the meanings assigned to them in the Indenture.

A.Establishment of a Series of Securities pursuant to Section 301 of the Indenture.

There is hereby established pursuant to Section 301 of the Indenture a series of Securities which shall have the following terms:

(1)The Securities shall bear the title “5.500% Notes due July 15, 2044” (referred to herein as the “Notes”).

(2)The aggregate principal amount of the Notes to be issued pursuant to this Officers’ Certificate and Company Order shall be limited to $1,500,000,000 except for (a) Notes authenticated and delivered upon registration of, transfer of, or in exchange for, or in lieu of, other Notes pursuant to Section 304, 305, 306, or 1007 of the Indenture, (b) Notes which, pursuant to Section 303 of the Indenture, are deemed never to have been authenticated and delivered thereunder and (c) any Securities of this series which are issued in the manner contemplated by paragraph 19(a) hereof.

(3)Interest shall be payable to the Person in whose name a Note (or any Predecessor Security) is registered at the close of business on the Regular Record Date (as defined below) immediately preceding each Interest Payment Date (as defined below). In the event that any Interest Payment Date, the date of maturity or any date of repurchase or Redemption Date falls on a date that is not a Business Day (as defined below), the related payment of principal and interest shall be postponed to the next succeeding Business Day, but the payment made on such date will be treated as being made on

the date that the payment was first due and the holders of the Notes (the “Holders”) shall not be entitled to any further interest or other payments with respect to such postponement. “Business Day” shall mean any day other than a Saturday, a Sunday or a day on which banking institutions in New York, New York or Minneapolis, Minnesota are authorized or required by law, regulation or executive order to close.

(4)The Stated Maturity of the Notes shall be July 15, 2044.

(5)The Notes shall bear interest at the rate of 5.500% per annum (based upon a 360-day year of twelve 30-day months), from July 25, 2024 or from the most recent Interest Payment Date to which interest has been paid or duly provided for, as the case may be, payable semi-annually in arrears on January 15 and July 15 in each year, commencing January 15, 2025, until the principal thereof is paid or made available for payment. Each such January 15 and July 15 shall be an “Interest Payment Date” for the Notes, and each January 1 or July 1 (whether or not a Business Day), as the case may be, immediately preceding an Interest Payment Date for the Notes shall be the “Regular Record Date” for the interest payable on such Interest Payment Date.

The provision related to interest on overdue principal in Section 501 of the Indenture shall not be applicable to the Notes.

(6)Principal of (and premium, if any) and interest on the Notes will be payable, and, except as provided in Section 305 of the Indenture with respect to a Global Security (as defined below), the transfer of the Notes will be registrable and Notes will be exchangeable for notes bearing identical terms and provisions at the corporate trust office of U.S. Bank Trust Company, National Association, in St. Paul, Minnesota. The method of such payment shall be by wire transfer for Notes held in book-entry form or at the option of the Company by check mailed to the Person entitled thereto as shown on the Security Register.

(7)Prior to January 15, 2044 (six months prior to the Stated Maturity) (the “Par Call Date”), the Notes will be redeemable at the Company’s 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:

(i)(a) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed 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 (as defined below), plus 15 basis points less (b) interest accrued to the Redemption Date, and

(ii)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 Notes will be redeemable 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 thereon to, but not including, 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 date 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) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (i) 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 (ii) 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 (iii) 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 TCM 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 Company shall notify the Trustee of the Redemption Price promptly after the calculation thereof and the Trustee shall not be responsible or liable for any calculation of the Redemption Price or of any component thereof, or for determining whether any manifest error has occurred. The Trustee may conclusively rely on an officer’s certificate setting forth a 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.

A notice of redemption may provide that it is subject to certain conditions that will be specified in the notice. If those conditions are not met, the redemption notice will be of no effect and the Company will not be obligated to redeem the Notes.

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.

(8)The Company shall not be obligated to redeem or purchase any Notes pursuant to any sinking fund or analogous provisions.

(9)If a Change of Control Triggering Event (as defined below) occurs, unless the Company has exercised its option to redeem all the Notes of this series, the Company shall be required to make an offer (a “Change of Control Offer”) to each Holder of the Notes of this series to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth herein. In a Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes of this series repurchased, plus accrued and unpaid interest, if any, on the Notes of this series repurchased to, but not including, the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be transmitted to Holders of the Notes of this series describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is transmitted (a “Change of Control Payment Date”). The notice shall, if transmitted prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

In order to accept the Change of Control Offer, the Holder must deliver to the Paying Agent, at least five Business Days prior to the Change of Control Payment Date, the Holder’s Note together with the form entitled “Election Form” (which form is annexed to the Note) duly completed, or a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange, or the Financial Industry Regulatory Authority or a commercial bank or trust company in the United States setting forth:

(i)the name of the Holder of the Note;

(ii)the principal amount of the Note;

(iii)the principal amount of the Note to be repurchased;

(iv)the certificate number or a description of the tenor and terms of the Note;

(v)a statement that the Holder is accepting the Change of Control Offer; and

(vi)a guarantee that the Note, together with the form entitled “Election Form” duly completed, will be received by the Paying Agent at least five Business Days prior to the Change of Control Payment Date.

Any exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable. The Change of Control Offer may be accepted for less than the entire principal amount of the Note, but in that event the principal amount of the Note remaining outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess thereof.

On the Change of Control Payment Date, the Company shall, to the extent lawful:

(i)accept for payment all Notes of this series or portions of such Notes properly tendered pursuant to the Change of Control Offer;

(ii)deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes of this series or portions of such Notes properly tendered; and

(iii)deliver or cause to be delivered to the Trustee the Notes of this series properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes of this series or portions of such Notes being repurchased.

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 third party purchases all Notes of this series properly tendered and not withdrawn under its offer. In addition, the Company shall not repurchase any Notes of this series if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

The Company shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes of this series as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes of this series, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes of this series by virtue of any such conflict.

•“Change of Control” means the occurrence of any 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 more series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any person, other than 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 Company’s outstanding Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; (3) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of the Company’s outstanding Voting Stock 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 Company’s Voting Stock 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 direct or indirect parent company of the surviving person immediately after giving effect to such transaction; (4) the first day on which a majority of the members of the Company’s Board of Directors are not Continuing Directors; or (5) the adoption of a plan relating to the Company’s liquidation or dissolution.

This Note is one of the series designated on the face hereof, limited in initial aggregate principal amount to $1,500,000,000; provided, however, that the Company may, so long as no Event of Default has occurred and is continuing, without the consent of the Holders of the Notes of this series, issue additional notes with the same terms as the Notes of this series, and such additional notes shall be considered part of the same series under the Indenture as the Notes of this series.

Prior to January 15, 2044 (six months prior to the Stated Maturity) (the “Par Call Date”), this Note is redeemable at the Company’s 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:

(i)(a) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be redeemed 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 (as defined below), plus 15 basis points less (b) interest accrued to the Redemption Date, and

(ii)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, this Note will be redeemable 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 this Note to be redeemed plus accrued and unpaid interest thereon to, but not including, 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 date 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) (“H.15 TCM”). In determining the Treasury Rate, the Company shall select, as applicable: (i) 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 (ii) 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 (iii) 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 TCM 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 Company shall notify the Trustee of the Redemption Price promptly after the calculation thereof and the Trustee shall not be responsible or liable for any calculation of the Redemption Price or of any component thereof, or for determining whether any manifest error has occurred. The Trustee may conclusively rely on an officer’s certificate setting forth a 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.

A notice of redemption may provide that it is subject to certain conditions that will be specified in the notice. If those conditions are not met, the redemption notice will be of no effect and the Company will not be obligated to redeem this Note.

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the Trustee in its sole discretion deems appropriate and fair. 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 such Note will state the portion of the principal amount of such Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of such 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 such notes are held by The Depository Trust Company, a New York corporation (or another depository), the redemption of such 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.

This Note will not be entitled to any sinking fund.

If a Change of Control Triggering Event (as defined herein) occurs, unless the Company has exercised its option to redeem all the Notes of this series, the Company shall be required to make an offer (a “Change of Control Offer”) to each Holder of the Notes of this series to repurchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of that Holder’s Notes on the terms set forth herein. In a Change of Control Offer, the Company shall be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes of this series repurchased, plus accrued and unpaid interest, if any, on the Notes of this series repurchased to, but not including, the date of repurchase (a “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at the Company’s option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice shall be transmitted to Holders of the Notes of this series describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Notes on the date specified in the notice, which date shall be no earlier than 30 days and no later than 60 days from the date such notice is transmitted (a “Change of Control Payment Date”). The notice shall, if transmitted prior to the date of consummation of the Change of Control, state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

In order to accept the Change of Control Offer, the Holder must deliver to the Paying Agent, at least five Business Days prior to the Change of Control Payment Date, this Note together with the form entitled “Election Form” (which form is annexed hereto) duly completed, or a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange, or the Financial Industry Regulatory Authority or a commercial bank or trust company in the United States setting forth:

(i)the name of the Holder of this Note;

(ii)the principal amount of this Note;

(iii)the principal amount of this Note to be repurchased;

(iv)the certificate number or a description of the tenor and terms of this Note;

(v)a statement that the Holder is accepting the Change of Control Offer; and

(vi)a guarantee that this Note, together with the form entitled “Election Form” duly completed, will be received by the Paying Agent at least five Business Days prior to the Change of Control Payment Date.

Any exercise by a Holder of its election to accept the Change of Control Offer shall be irrevocable. The Change of Control Offer may be accepted for less than the entire principal amount of this Note, but in that event the principal amount of this Note remaining outstanding after repurchase must be equal to $2,000 or an integral multiple of $1,000 in excess thereof.

On the Change of Control Payment Date, the Company shall, to the extent lawful:

(i)accept for payment all Notes of this series or portions of such Notes properly tendered pursuant to the Change of Control Offer;

(ii)deposit with the Paying Agent an amount equal to the Change of Control Payment in respect of all Notes of this series or portions of such Notes properly tendered; and

(iii)deliver or cause to be delivered to the Trustee the Notes of this series properly accepted together with an Officers’ Certificate stating the aggregate principal amount of Notes of this series or portions of such Notes being repurchased.

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 third party purchases all Notes of this series properly tendered and not withdrawn under its offer. In addition, the Company shall not repurchase any Notes of this series if there has occurred and is continuing on the Change of Control Payment Date an Event of Default under the Indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

The Company shall comply with the requirements of Rule 14e-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Notes of this series as a result of a Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes of this series, the Company shall comply with those securities laws and regulations and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes of this series by virtue of any such conflict.

For purposes of the Change of Control Offer provisions of the Notes of this series, the following terms are applicable:

•“Change of Control” means the occurrence of any 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 more series of related transactions, of all or substantially all of the assets of the Company and its Subsidiaries, taken as a whole, to any person, other than 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 Company’s outstanding Voting Stock or other Voting Stock into which the Company’s Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; (3) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of the Company’s outstanding Voting Stock 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 Company’s Voting Stock 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 direct or indirect parent company of the surviving person immediately after giving effect to such transaction; (4) the first day on which a majority of the members of the Company’s Board of Directors are not Continuing Directors; or (5) the adoption of a plan relating to the Company’s liquidation or dissolution.

The Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Securities of any series at the time Outstanding to waive 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 Notes 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 Note.
