ALPHABET INC., a Delaware corporation (the “Company”, which term includes any successor thereto under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to The Bank of New York Depositary (Nominees) Limited, as nominee of The Bank of New York Mellon, London Branch, as common depositary for Clearstream

Banking, S.A. (“Clearstream”) and Euroclear Bank S.A./N.V. (“Euroclear”), or their registered assigns, at the office or agency of the Paying Agent maintained for such purpose, which shall initially be the corporate trust office of the Paying Agent, the principal sum of ONE BILLION EUROS (€1,000,000,000) (or such other principal amount as shall be set forth in the Schedule of Increases or Decreases in Note attached hereto) on November 6, 2028, and to pay interest thereon from November 6, 2025 or from the next preceding Interest Payment Date in respect of which interest has been paid or duly provided for, annually in arrears on November 6 of each year, beginning on November 6, 2026 on said principal sum, at the rate of 2.375% per annum, on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid (or November 6, 2025 if no interest has been paid), to, but not including, the next scheduled Interest Payment Date, until the principal hereof is paid or duly provided for or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at such rate on any overdue principal and premium and on any overdue installment of interest.

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 Security (or one or more Predecessor Securities) is registered at the close of business on the Record Date for such interest, which shall be the close of business on the date that is the Clearing System Business Day immediately preceding each Interest Payment Date. A Clearing System Business Day is every Monday to Friday inclusive, except December 25th and January 1st. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the person in whose name this Security (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 whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as, more fully provided in said Indenture.

As used in this Security, the term “Business Day” means any day, other than a Saturday or Sunday, (1) which is not a day on which banking institutions in the City of New York or the City of London are authorized or required by law or executive order to close and (2) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates.

Initially, The Bank of New York Mellon, London Branch, will act as Paying Agent. The Company may change the Paying Agent without notice to any Holder. Payment of the principal, premium, if any, and interest on the Securities of this series will be made at the office or agency maintained for that purpose in London (initially the corporate trust office of the Paying Agent); provided that payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Register or by wire transfer as provided in the Indenture.

The term “euros,” “the euro” or “€” means the currency of the member states of the European Monetary Union that have adopted or that adopt the single currency in accordance with the treaty establishing the European Community, as amended by the Treaty on European Union.

All payments on the Securities of this series will be payable in euros; provided that if on or after November 3, 2025, the euro is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Securities of this series will be made in U.S. dollars until the euro is again available to the Company or so used. The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. Dollar/euro exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date. Any payment in respect of the Securities of this series so made in U.S. dollars will not constitute an event of default under the Securities of this series or the Indenture. Neither the Trustee nor the Paying Agent will have any responsibility for any calculation or conversion in connection with the foregoing.

Reference is made to the further provisions of this Security set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Security shall not be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been manually signed by the Trustee under the Indenture referred to on the reverse hereof.

IN WITNESS WHEREOF, ALPHABET INC. has caused this instrument to be duly executed.

REVERSE OF SECURITY

ALPHABET INC.

2.375% Notes Due 2028

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 2.375% Notes due 2028 of the Company, limited in aggregate principal amount to €1,000,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP, ISIN or other identifying number unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Securities of this series (or November 6, 2025 if no interest has been paid on the Securities of this series), to, but not including, the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 2.375% Notes due 2028 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of €100,000 and multiples of €1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 6, 2028 at the Company’s option in whole or in part at any time or from time to time. Prior to October 6, 2028, the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the Redemption Date), discounted to the Redemption Date on an annual basis (ACTUAL/ACTUAL (ICMA)), at the applicable Comparable Government Bond Rate described below plus 10 basis points plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after October 6, 2028, the Company may redeem the Securities of this series by paying a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “Comparable Government Bond Rate” means, with respect to any Redemption Date, the rate per annum equal to the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, calculated in accordance with customary financial practice in pricing new issues of comparable corporate debt securities paying interest on an annual basis (ACTUAL/ACTUAL (ICMA)) of the Comparable Government Bond (as defined below), assuming a price for the Comparable Government Bond (expressed as a percentage of its principal amount) equal to the Comparable Government Bond Price for such Redemption Date. “Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, the German government bond (Bundesanleihe) selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities of a comparable maturity to the remaining term of such Securities. “Independent Investment Banker” means one of the Reference Government Bond Dealers selected by the Company. “Comparable Government Bond Price” means, with respect to any Redemption Date, (1) the arithmetic average of the Reference Government Bond Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Government Bond Dealer Quotations, or (2) if the Company obtains fewer than four such Reference Government Bond Dealer Quotations, the arithmetic average of all such quotations. “Reference Government Bond Dealer Quotations” means, with respect to each Reference Government Bond Dealer and any Redemption Date, the arithmetic average, as determined by the Company, of the bid and asked prices for the Comparable Government Bond (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Government Bond Dealer at 11:00 a.m., Central European Time (CET), on the third Business Day preceding such Redemption Date. “Reference Government Bond Dealer” means (i) each of Goldman Sachs & Co. LLC, HSBC Bank plc, J.P. Morgan Securities plc, BNP PARIBAS, Crédit Agricole Corporate and Investment Bank and Deutsche Bank AG, London Branch, or any of their affiliates that are primary European government securities dealers, and their respective successors; provided that if any of the foregoing or any of their affiliates shall cease to be a primary European government securities dealer (“Primary Dealer”), the Company shall substitute therefor another Primary Dealer and (ii) two other Primary Dealers selected by the Company.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with Clearstream or Euroclear procedures, as applicable) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of €1,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by Clearstream or Euroclear, as applicable, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of the applicable clearing system.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Subject to the exceptions and limitations set forth below, the Company will pay as additional interest on the Securities of this series such additional amounts as are necessary in order that the net payment by the Company or a paying agent of the principal, premium, if any, and interest with respect to the Securities of this series to the beneficial owner that is not a United States person (as defined below), after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in this Security to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts will not apply:

Except as specifically provided above, the Company will not be required to pay additional amounts in respect of any tax, assessment or other governmental charge. References in this Security to any payment on the Securities include the related payment of additional amounts, as applicable.

The term “United States” means the United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S. federal income tax purposes), (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S. court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person.

If, as a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after April 29, 2025, the Company becomes or, based upon a written opinion of independent counsel selected by the Company, will become obligated to pay additional amounts as described above with respect to the Securities of this series, then the Company may at any time at its option redeem, in whole, but not in part, the Securities of this series on not less than 10 nor more than 60 days’ prior notice, at a Redemption Price equal to 100% of their principal amount, plus accrued and unpaid interest, if any, on the Securities to be redeemed to, but not including, the Redemption Date.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.

For purposes of the provisions relating to satisfaction and discharge above, “Foreign Government Securities” means securities that are (i) direct obligations of the government that issued or caused to be issued such currency for the payment of which obligations its full faith and credit is pledged or (ii) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of such government the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by such government, which, in either case under clause (i) or (ii), are not callable or redeemable at the option of the issuer thereof.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered Holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and, subject to the provisions hereof, interest hereon, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

Banking, S.A. (“Clearstream”) and Euroclear Bank S.A./N.V. (“Euroclear”), or their registered assigns, at the office or agency of the Paying Agent maintained for such purpose, which shall initially be the corporate trust office of the Paying Agent, the principal sum of ONE BILLION EUROS (€1,000,000,000) (or such other principal amount as shall be set forth in the Schedule of Increases or Decreases in Note attached hereto) on November 6, 2031, and to pay interest thereon from November 6, 2025 or from the next preceding Interest Payment Date in respect of which interest has been paid or duly provided for, annually in arrears on November 6 of each year, beginning on November 6, 2026 on said principal sum, at the rate of 2.875% per annum, on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid (or November 6, 2025 if no interest has been paid), to, but not including, the next scheduled Interest Payment Date, until the principal hereof is paid or duly provided for or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at such rate on any overdue principal and premium and on any overdue installment of interest.

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 Security (or one or more Predecessor Securities) is registered at the close of business on the Record Date for such interest, which shall be the close of business on the date that is the Clearing System Business Day immediately preceding each Interest Payment Date. A Clearing System Business Day is every Monday to Friday inclusive, except December 25th and January 1st. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the person in whose name this Security (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 whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as, more fully provided in said Indenture.

As used in this Security, the term “Business Day” means any day, other than a Saturday or Sunday, (1) which is not a day on which banking institutions in the City of New York or the City of London are authorized or required by law or executive order to close and (2) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates.

Initially, The Bank of New York Mellon, London Branch, will act as Paying Agent. The Company may change the Paying Agent without notice to any Holder. Payment of the principal, premium, if any, and interest on the Securities of this series will be made at the office or agency maintained for that purpose in London (initially the corporate trust office of the Paying Agent); provided that payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Register or by wire transfer as provided in the Indenture.

The term “euros,” “the euro” or “€” means the currency of the member states of the European Monetary Union that have adopted or that adopt the single currency in accordance with the treaty establishing the European Community, as amended by the Treaty on European Union.

All payments on the Securities of this series will be payable in euros; provided that if on or after November 3, 2025, the euro is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Securities of this series will be made in U.S. dollars until the euro is again available to the Company or so used. The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. Dollar/euro exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date. Any payment in respect of the Securities of this series so made in U.S. dollars will not constitute an event of default under the Securities of this series or the Indenture. Neither the Trustee nor the Paying Agent will have any responsibility for any calculation or conversion in connection with the foregoing.

Reference is made to the further provisions of this Security set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Security shall not be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been manually signed by the Trustee under the Indenture referred to on the reverse hereof.

REVERSE OF SECURITY

ALPHABET INC.

2.875% Notes Due 2031

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 2.875% Notes due 2031 of the Company, limited in aggregate principal amount to €1,000,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP, ISIN or other identifying number unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Securities of this series (or November 6, 2025 if no interest has been paid on the Securities of this series), to, but not including, the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 2.875% Notes due 2031 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of €100,000 and multiples of €1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 6, 2031 at the Company’s option in whole or in part at any time or from time to time. Prior to September 6, 2031, the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the Redemption Date), discounted to the Redemption Date on an annual basis (ACTUAL/ACTUAL (ICMA)), at the applicable Comparable Government Bond Rate described below plus 10 basis points plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after September 6, 2031, the Company may redeem the Securities of this series by paying a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “Comparable Government Bond Rate” means, with respect to any Redemption Date, the rate per annum equal to the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, calculated in accordance with customary financial practice in pricing new issues of comparable corporate debt securities paying interest on an annual basis (ACTUAL/ACTUAL (ICMA)) of the Comparable Government Bond (as defined below), assuming a price for the Comparable Government Bond (expressed as a percentage of its principal amount) equal to the Comparable Government Bond Price for such Redemption Date. “Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, the German government bond (Bundesanleihe) selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities of a comparable maturity to the remaining term of such Securities. “Independent Investment Banker” means one of the Reference Government Bond Dealers selected by the Company. “Comparable Government Bond Price” means, with respect to any Redemption Date, (1) the arithmetic average of the Reference Government Bond Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Government Bond Dealer Quotations, or (2) if the Company obtains fewer than four such Reference Government Bond Dealer Quotations, the arithmetic average of all such quotations. “Reference Government Bond Dealer Quotations” means, with respect to each Reference Government Bond Dealer and any Redemption Date, the arithmetic average, as determined by the Company, of the bid and asked prices for the Comparable Government Bond (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Government Bond Dealer at 11:00 a.m., Central European Time (CET), on the third Business Day preceding such Redemption Date. “Reference Government Bond Dealer” means (i) each of Goldman Sachs & Co. LLC, HSBC Bank plc, J.P. Morgan Securities plc, BNP PARIBAS, Crédit Agricole Corporate and Investment Bank and Deutsche Bank AG, London Branch, or any of their affiliates that are primary European government securities dealers, and their respective successors; provided that if any of the foregoing or any of their affiliates shall cease to be a primary European government securities dealer (“Primary Dealer”), the Company shall substitute therefor another Primary Dealer and (ii) two other Primary Dealers selected by the Company.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with Clearstream or Euroclear procedures, as applicable) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of €1,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by Clearstream or Euroclear, as applicable, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of the applicable clearing system.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Subject to the exceptions and limitations set forth below, the Company will pay as additional interest on the Securities of this series such additional amounts as are necessary in order that the net payment by the Company or a paying agent of the principal, premium, if any, and interest with respect to the Securities of this series to the beneficial owner that is not a United States person (as defined below), after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in this Security to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts will not apply:

Except as specifically provided above, the Company will not be required to pay additional amounts in respect of any tax, assessment or other governmental charge. References in this Security to any payment on the Securities include the related payment of additional amounts, as applicable.

The term “United States” means the United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S. federal income tax purposes), (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S. court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person.

If, as a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after April 29, 2025, the Company becomes or, based upon a written opinion of independent counsel selected by the Company, will become obligated to pay additional amounts as described above with respect to the Securities of this series, then the Company may at any time at its option redeem, in whole, but not in part, the Securities of this series on not less than 10 nor more than 60 days’ prior notice, at a Redemption Price equal to 100% of their principal amount, plus accrued and unpaid interest, if any, on the Securities to be redeemed to, but not including, the Redemption Date.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(A) have become due and payable, or

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.

For purposes of the provisions relating to satisfaction and discharge above, “Foreign Government Securities” means securities that are (i) direct obligations of the government that issued or caused to be issued such currency for the payment of which obligations its full faith and credit is pledged or (ii) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of such government the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by such government, which, in either case under clause (i) or (ii), are not callable or redeemable at the option of the issuer thereof.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

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 Security (or one or more Predecessor Securities) is registered at the close of business on the Record Date for such interest, which shall be the close of business on the date that is the Clearing System Business Day immediately preceding each Interest Payment Date. A Clearing System Business Day is every Monday to Friday inclusive, except December 25th and January 1st. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the person in whose name this Security (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 whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as, more fully provided in said Indenture.

As used in this Security, the term “Business Day” means any day, other than a Saturday or Sunday, (1) which is not a day on which banking institutions in the City of New York or the City of London are authorized or required by law or executive order to close and (2) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates.

Initially, The Bank of New York Mellon, London Branch, will act as Paying Agent. The Company may change the Paying Agent without notice to any Holder. Payment of the principal, premium, if any, and interest on the Securities of this series will be made at the office or agency maintained for that purpose in London (initially the corporate trust office of the Paying Agent); provided that payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Register or by wire transfer as provided in the Indenture.

The term “euros,” “the euro” or “€” means the currency of the member states of the European Monetary Union that have adopted or that adopt the single currency in accordance with the treaty establishing the European Community, as amended by the Treaty on European Union.

The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. Dollar/euro exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date. Any payment in respect of the Securities of this series so made in U.S. dollars will not constitute an event of default under the Securities of this series or the Indenture. Neither the Trustee nor the Paying Agent will have any responsibility for any calculation or conversion in connection with the foregoing.

Reference is made to the further provisions of this Security set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Security shall not be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been manually signed by the Trustee under the Indenture referred to on the reverse hereof.

REVERSE OF SECURITY

ALPHABET INC.

3.125% Notes Due 2034

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 3.125% Notes due 2034 of the Company, limited in aggregate principal amount to €1,000,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP, ISIN or other identifying number unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Securities of this series (or November 6, 2025 if no interest has been paid on the Securities of this series), to, but not including, the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 3.125% Notes due 2034 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of €100,000 and multiples of €1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 6, 2034 at the Company’s option in whole or in part at any time or from time to time. Prior to August 6, 2034, the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the Redemption Date), discounted to the Redemption Date on an annual basis (ACTUAL/ACTUAL (ICMA)), at the applicable Comparable Government Bond Rate described below plus 10 basis points plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after August 6, 2034, the Company may redeem the Securities of this series by paying a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “Comparable Government Bond Rate” means, with respect to any Redemption Date, the rate per annum equal to the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, calculated in accordance with customary financial practice in pricing new issues of comparable corporate debt securities paying interest on an annual basis (ACTUAL/ACTUAL (ICMA)) of the Comparable Government Bond (as defined below), assuming a price for the Comparable Government Bond (expressed as a percentage of its principal amount) equal to the Comparable Government Bond Price for such Redemption Date. “Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, the German government bond (Bundesanleihe) selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities of a comparable maturity to the remaining term of such Securities. “Independent Investment Banker” means one of the Reference Government Bond Dealers selected by the Company. “Comparable Government Bond Price” means, with respect to any Redemption Date, (1) the arithmetic average of the Reference Government Bond Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Government Bond Dealer Quotations, or (2) if the Company obtains fewer than four such Reference Government Bond Dealer Quotations, the arithmetic average of all such quotations. “Reference Government Bond Dealer Quotations” means, with respect to each Reference Government Bond Dealer and any Redemption Date, the arithmetic average, as determined by the Company, of the bid and asked prices for the Comparable Government Bond (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Government Bond Dealer at 11:00 a.m., Central European Time (CET), on the third Business Day preceding such Redemption Date. “Reference Government Bond Dealer” means (i) each of Goldman Sachs & Co. LLC, HSBC Bank plc, J.P. Morgan Securities plc, BNP PARIBAS, Crédit Agricole Corporate and Investment Bank and Deutsche Bank AG, London Branch, or any of their affiliates that are primary European government securities dealers, and their respective successors; provided that if any of the foregoing or any of their affiliates shall cease to be a primary European government securities dealer (“Primary Dealer”), the Company shall substitute therefor another Primary Dealer and (ii) two other Primary Dealers selected by the Company.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with Clearstream or Euroclear procedures, as applicable) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of €1,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by Clearstream or Euroclear, as applicable, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of the applicable clearing system.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Subject to the exceptions and limitations set forth below, the Company will pay as additional interest on the Securities of this series such additional amounts as are necessary in order that the net payment by the Company or a paying agent of the principal, premium, if any, and interest with respect to the Securities of this series to the beneficial owner that is not a United States person (as defined below), after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in this Security to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts will not apply:

Except as specifically provided above, the Company will not be required to pay additional amounts in respect of any tax, assessment or other governmental charge. References in this Security to any payment on the Securities include the related payment of additional amounts, as applicable.

The term “United States” means the United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S. federal income tax purposes), (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S. court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person.

If, as a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after April 29, 2025, the Company becomes or, based upon a written opinion of independent counsel selected by the Company, will become obligated to pay additional amounts as described above with respect to the Securities of this series, then the Company may at any time at its option redeem, in whole, but not in part, the Securities of this series on not less than 10 nor more than 60 days’ prior notice, at a Redemption Price equal to 100% of their principal amount, plus accrued and unpaid interest, if any, on the Securities to be redeemed to, but not including, the Redemption Date.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Foreign Government Securities that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

ALPHABET INC., a Delaware corporation (the “Company”, which term includes any successor thereto under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to The Bank of New York Depositary (Nominees) Limited, as nominee of The Bank of New York Mellon, London Branch, as common depositary for Clearstream Banking, S.A. (“Clearstream”) and Euroclear Bank S.A./N.V. (“Euroclear”), or their registered assigns, at the office or agency of the Paying Agent maintained for such purpose, which shall initially be the corporate trust office of the Paying Agent, the principal sum of ONE BILLION EUROS (€1,000,000,000) (or such other principal amount as shall be set forth in the Schedule of Increases or Decreases in Note attached hereto) on November 6, 2038, and to pay interest thereon from November 6, 2025 or from the next preceding Interest Payment Date in respect of which interest has been paid or duly provided for, annually in arrears on November 6 of each year, beginning on November 6, 2026 on said principal sum, at the rate of 3.500% per annum, on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid (or November 6, 2025 if no interest has been paid), to, but not including, the next scheduled Interest Payment Date, until the principal hereof is paid or duly provided for or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at such rate on any overdue principal and premium and on any overdue installment of interest.

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 Security (or one or more Predecessor Securities) is registered at the close of business on the Record Date for such interest, which shall be the close of business on the date that is the Clearing System Business Day immediately preceding each Interest Payment Date. A Clearing System Business Day is every Monday to Friday inclusive, except December 25th and January 1st. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the person in whose name this Security (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 whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as, more fully provided in said Indenture.

As used in this Security, the term “Business Day” means any day, other than a Saturday or Sunday, (1) which is not a day on which banking institutions in the City of New York or the City of London are authorized or required by law or executive order to close and (2) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates.

Initially, The Bank of New York Mellon, London Branch, will act as Paying Agent. The Company may change the Paying Agent without notice to any Holder. Payment of the principal, premium, if any, and interest on the Securities of this series will be made at the office or agency maintained for that purpose in London (initially the corporate trust office of the Paying Agent); provided that payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Register or by wire transfer as provided in the Indenture.

The term “euros,” “the euro” or “€” means the currency of the member states of the European Monetary Union that have adopted or that adopt the single currency in accordance with the treaty establishing the European Community, as amended by the Treaty on European Union.

All payments on the Securities of this series will be payable in euros; provided that if on or after November 3, 2025, the euro is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Securities of this series will be made in U.S. dollars until the euro is again available to the Company or so used. The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. Dollar/euro exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date. Any payment in respect of the Securities of this series so made in U.S. dollars will not constitute an event of default under the Securities of this series or the Indenture. Neither the Trustee nor the Paying Agent will have any responsibility for any calculation or conversion in connection with the foregoing.

Reference is made to the further provisions of this Security set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Security shall not be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been manually signed by the Trustee under the Indenture referred to on the reverse hereof.

REVERSE OF SECURITY

ALPHABET INC.

3.500% Notes Due 2038

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 3.500% Notes due 2038 of the Company, limited in aggregate principal amount to €1,000,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP, ISIN or other identifying number unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Securities of this series (or November 6, 2025 if no interest has been paid on the Securities of this series), to, but not including, the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 3.500% Notes due 2038 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of €100,000 and multiples of €1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 6, 2038 at the Company’s option in whole or in part at any time or from time to time. Prior to August 6, 2038, the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the Redemption Date), discounted to the Redemption Date on an annual basis (ACTUAL/ACTUAL (ICMA)), at the applicable Comparable Government Bond Rate described below plus 15 basis points plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after August 6, 2038, the Company may redeem the Securities of this series by paying a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “Comparable Government Bond Rate” means, with respect to any Redemption Date, the rate per annum equal to the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, calculated in accordance with customary financial practice in pricing new issues of comparable corporate debt securities paying interest on an annual basis (ACTUAL/ACTUAL (ICMA)) of the Comparable Government Bond (as defined below), assuming a price for the Comparable Government Bond (expressed as a percentage of its principal amount) equal to the Comparable Government Bond Price for such Redemption Date. “Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, the German government bond (Bundesanleihe) selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities of a comparable maturity to the remaining term of such Securities. “Independent Investment Banker” means one of the Reference Government Bond Dealers selected by the Company. “Comparable Government Bond Price” means, with respect to any Redemption Date, (1) the arithmetic average of the Reference Government Bond Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Government Bond Dealer Quotations, or (2) if the Company obtains fewer than four such Reference Government Bond Dealer Quotations, the arithmetic average of all such quotations. “Reference Government Bond Dealer Quotations” means, with respect to each Reference Government Bond Dealer and any Redemption Date, the arithmetic average, as determined by the Company, of the bid and asked prices for the Comparable Government Bond (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Government Bond Dealer at 11:00 a.m., Central European Time (CET), on the third Business Day preceding such Redemption Date. “Reference Government Bond Dealer” means (i) each of Goldman Sachs & Co. LLC, HSBC Bank plc, J.P. Morgan Securities plc, BNP PARIBAS, Crédit Agricole Corporate and Investment Bank and Deutsche Bank AG, London Branch, or any of their affiliates that are primary European government securities dealers, and their respective successors; provided that if any of the foregoing or any of their affiliates shall cease to be a primary European government securities dealer (“Primary Dealer”), the Company shall substitute therefor another Primary Dealer and (ii) two other Primary Dealers selected by the Company.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with Clearstream or Euroclear procedures, as applicable) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of €1,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by Clearstream or Euroclear, as applicable, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of the applicable clearing system.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Subject to the exceptions and limitations set forth below, the Company will pay as additional interest on the Securities of this series such additional amounts as are necessary in order that the net payment by the Company or a paying agent of the principal, premium, if any, and interest with respect to the Securities of this series to the beneficial owner that is not a United States person (as defined below), after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in this Security to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts will not apply:

Except as specifically provided above, the Company will not be required to pay additional amounts in respect of any tax, assessment or other governmental charge. References in this Security to any payment on the Securities include the related payment of additional amounts, as applicable.

The term “United States” means the United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S. federal income tax purposes), (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S. court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person.

If, as a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after April 29, 2025, the Company becomes or, based upon a written opinion of independent counsel selected by the Company, will become obligated to pay additional amounts as described above with respect to the Securities of this series, then the Company may at any time at its option redeem, in whole, but not in part, the Securities of this series on not less than 10 nor more than 60 days’ prior notice, at a Redemption Price equal to 100% of their principal amount, plus accrued and unpaid interest, if any, on the Securities to be redeemed to, but not including, the Redemption Date.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(A) have become due and payable, or

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.

For purposes of the provisions relating to satisfaction and discharge above, “Foreign Government Securities” means securities that are (i) direct obligations of the government that issued or caused to be issued such currency for the payment of which obligations its full faith and credit is pledged or (ii) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of such government the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by such government, which, in either case under clause (i) or (ii), are not callable or redeemable at the option of the issuer thereof.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

ALPHABET INC., a Delaware corporation (the “Company”, which term includes any successor thereto under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to The Bank of New York Depositary (Nominees) Limited, as nominee of The Bank of New York Mellon, London Branch, as common depositary for Clearstream

Banking, S.A. (“Clearstream”) and Euroclear Bank S.A./N.V. (“Euroclear”), or their registered assigns, at the office or agency of the Paying Agent maintained for such purpose, which shall initially be the corporate trust office of the Paying Agent, the principal sum of ONE BILLION TWO HUNDRED AND FIFTY MILLION EUROS (€1,250,000,000) (or such other principal amount as shall be set forth in the Schedule of Increases or Decreases in Note attached hereto) on November 6, 2044, and to pay interest thereon from November 6, 2025 or from the next preceding Interest Payment Date in respect of which interest has been paid or duly provided for, annually in arrears on November 6 of each year, beginning on November 6, 2026 on said principal sum, at the rate of 4.000% per annum, on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid (or November 6, 2025 if no interest has been paid), to, but not including, the next scheduled Interest Payment Date, until the principal hereof is paid or duly provided for or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at such rate on any overdue principal and premium and on any overdue installment of interest.

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 Security (or one or more Predecessor Securities) is registered at the close of business on the Record Date for such interest, which shall be the close of business on the date that is the Clearing System Business Day immediately preceding each Interest Payment Date. A Clearing System Business Day is every Monday to Friday inclusive, except December 25th and January 1st. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the person in whose name this Security (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 whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as, more fully provided in said Indenture.

As used in this Security, the term “Business Day” means any day, other than a Saturday or Sunday, (1) which is not a day on which banking institutions in the City of New York or the City of London are authorized or required by law or executive order to close and (2) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates.

Initially, The Bank of New York Mellon, London Branch, will act as Paying Agent. The Company may change the Paying Agent without notice to any Holder. Payment of the principal, premium, if any, and interest on the Securities of this series will be made at the office or agency maintained for that purpose in London (initially the corporate trust office of the Paying Agent); provided that payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Register or by wire transfer as provided in the Indenture.

The term “euros,” “the euro” or “€” means the currency of the member states of the European Monetary Union that have adopted or that adopt the single currency in accordance with the treaty establishing the European Community, as amended by the Treaty on European Union.

All payments on the Securities of this series will be payable in euros; provided that if on or after November 3, 2025, the euro is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Securities of this series will be made in U.S. dollars until the euro is again available to the Company or so used. The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. Dollar/euro exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date. Any payment in respect of the Securities of this series so made in U.S. dollars will not constitute an event of default under the Securities of this series or the Indenture. Neither the Trustee nor the Paying Agent will have any responsibility for any calculation or conversion in connection with the foregoing.

Reference is made to the further provisions of this Security set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Security shall not be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been manually signed by the Trustee under the Indenture referred to on the reverse hereof.

IN WITNESS WHEREOF, ALPHABET INC. has caused this instrument to be duly executed.

REVERSE OF SECURITY

ALPHABET INC.

4.000% Notes Due 2044

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 4.000% Notes due 2044 of the Company, limited in aggregate principal amount to €1,250,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP, ISIN or other identifying number unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Securities of this series (or November 6, 2025 if no interest has been paid on the Securities of this series), to, but not including, the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 4.000% Notes due 2044 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of €100,000 and multiples of €1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 6, 2044 at the Company’s option in whole or in part at any time or from time to time. Prior to May 6, 2044, the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the Redemption Date), discounted to the Redemption Date on an annual basis (ACTUAL/ACTUAL (ICMA)), at the applicable Comparable Government Bond Rate described below plus 15 basis points plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after May 6, 2044, the Company may redeem the Securities of this series by paying a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “Comparable Government Bond Rate” means, with respect to any Redemption Date, the rate per annum equal to the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, calculated in accordance with customary financial practice in pricing new issues of comparable corporate debt securities paying interest on an annual basis (ACTUAL/ACTUAL (ICMA)) of the Comparable Government Bond (as defined below), assuming a price for the Comparable Government Bond (expressed as a percentage of its principal amount) equal to the Comparable Government Bond Price for such Redemption Date. “Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, the German government bond (Bundesanleihe) selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities of a comparable maturity to the remaining term of such Securities. “Independent Investment Banker” means one of the Reference Government Bond Dealers selected by the Company. “Comparable Government Bond Price” means, with respect to any Redemption Date, (1) the arithmetic average of the Reference Government Bond Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Government Bond Dealer Quotations, or (2) if the Company obtains fewer than four such Reference Government Bond Dealer Quotations, the arithmetic average of all such quotations. “Reference Government Bond Dealer Quotations” means, with respect to each Reference Government Bond Dealer and any Redemption Date, the arithmetic average, as determined by the Company, of the bid and asked prices for the Comparable Government Bond (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Government Bond Dealer at 11:00 a.m., Central European Time (CET), on the third Business Day preceding such Redemption Date. “Reference Government Bond Dealer” means (i) each of Goldman Sachs & Co. LLC, HSBC Bank plc, J.P. Morgan Securities plc, BNP PARIBAS, Crédit Agricole Corporate and Investment Bank and Deutsche Bank AG, London Branch, or any of their affiliates that are primary European government securities dealers, and their respective successors; provided that if any of the foregoing or any of their affiliates shall cease to be a primary European government securities dealer (“Primary Dealer”), the Company shall substitute therefor another Primary Dealer and (ii) two other Primary Dealers selected by the Company.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with Clearstream or Euroclear procedures, as applicable) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of €1,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by Clearstream or Euroclear, as applicable, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of the applicable clearing system.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Subject to the exceptions and limitations set forth below, the Company will pay as additional interest on the Securities of this series such additional amounts as are necessary in order that the net payment by the Company or a paying agent of the principal, premium, if any, and interest with respect to the Securities of this series to the beneficial owner that is not a United States person (as defined below), after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in this Security to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts will not apply:

Except as specifically provided above, the Company will not be required to pay additional amounts in respect of any tax, assessment or other governmental charge. References in this Security to any payment on the Securities include the related payment of additional amounts, as applicable.

The term “United States” means the United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S. federal income tax purposes), (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S. court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person.

If, as a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after April 29, 2025, the Company becomes or, based upon a written opinion of independent counsel selected by the Company, will become obligated to pay additional amounts as described above with respect to the Securities of this series, then the Company may at any time at its option redeem, in whole, but not in part, the Securities of this series on not less than 10 nor more than 60 days’ prior notice, at a Redemption Price equal to 100% of their principal amount, plus accrued and unpaid interest, if any, on the Securities to be redeemed to, but not including, the Redemption Date.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(ii) all Securities of this series not theretofore delivered to the Trustee for cancellation,

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Foreign Government Securities that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.

For purposes of the provisions relating to satisfaction and discharge above, “Foreign Government Securities” means securities that are (i) direct obligations of the government that issued or caused to be issued such currency for the payment of which obligations its full faith and credit is pledged or (ii) obligations of a Person controlled or supervised by and acting as an agency or instrumentality of such government the timely payment of which is unconditionally guaranteed as a full faith and credit obligation by such government, which, in either case under clause (i) or (ii), are not callable or redeemable at the option of the issuer thereof.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered Holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and, subject to the provisions hereof, interest hereon, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

ALPHABET INC., a Delaware corporation (the “Company”, which term includes any successor thereto under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to The Bank of New York Depositary (Nominees) Limited, as nominee of The Bank of New York Mellon, London Branch, as common depositary for Clearstream

Banking, S.A. (“Clearstream”) and Euroclear Bank S.A./N.V. (“Euroclear”), or their registered assigns, at the office or agency of the Paying Agent maintained for such purpose, which shall initially be the corporate trust office of the Paying Agent, the principal sum of ONE BILLION TWO HUNDRED AND FIFTY MILLION EUROS (€1,250,000,000) (or such other principal amount as shall be set forth in the Schedule of Increases or Decreases in Note attached hereto) on November 6, 2064, and to pay interest thereon from November 6, 2025 or from the next preceding Interest Payment Date in respect of which interest has been paid or duly provided for, annually in arrears on November 6 of each year, beginning on November 6, 2026 on said principal sum, at the rate of 4.375% per annum, on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid (or November 6, 2025 if no interest has been paid), to, but not including, the next scheduled Interest Payment Date, until the principal hereof is paid or duly provided for or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at such rate on any overdue principal and premium and on any overdue installment of interest.

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 Security (or one or more Predecessor Securities) is registered at the close of business on the Record Date for such interest, which shall be the close of business on the date that is the Clearing System Business Day immediately preceding each Interest Payment Date. A Clearing System Business Day is every Monday to Friday inclusive, except December 25th and January 1st. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the person in whose name this Security (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 whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as, more fully provided in said Indenture.

As used in this Security, the term “Business Day” means any day, other than a Saturday or Sunday, (1) which is not a day on which banking institutions in the City of New York or the City of London are authorized or required by law or executive order to close and (2) on which the Trans-European Automated Real-time Gross Settlement Express Transfer system (the TARGET2 system), or any successor thereto, operates.

Initially, The Bank of New York Mellon, London Branch, will act as Paying Agent. The Company may change the Paying Agent without notice to any Holder. Payment of the principal, premium, if any, and interest on the Securities of this series will be made at the office or agency maintained for that purpose in London (initially the corporate trust office of the Paying Agent); provided that payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Register or by wire transfer as provided in the Indenture.

The term “euros,” “the euro” or “€” means the currency of the member states of the European Monetary Union that have adopted or that adopt the single currency in accordance with the treaty establishing the European Community, as amended by the Treaty on European Union.

All payments on the Securities of this series will be payable in euros; provided that if on or after November 3, 2025, the euro is unavailable to the Company due to the imposition of exchange controls or other circumstances beyond its control or if the euro is no longer being used by the then member states of the European Monetary Union that have adopted the euro as their currency or for the settlement of transactions by public institutions of or within the international banking community, then all payments in respect of the Securities of this series will be made in U.S. dollars until the euro is again available to the Company or so used. The amount payable on any date in euros will be converted into U.S. dollars at the rate mandated by the U.S. Federal Reserve Board as of the close of business on the second Business Day prior to the relevant payment date or, in the event the U.S. Federal Reserve Board has not mandated a rate of conversion, on the basis of the most recent U.S. Dollar/euro exchange rate published in The Wall Street Journal on or prior to the second Business Day prior to the relevant payment date. Any payment in respect of the Securities of this series so made in U.S. dollars will not constitute an event of default under the Securities of this series or the Indenture. Neither the Trustee nor the Paying Agent will have any responsibility for any calculation or conversion in connection with the foregoing.

Reference is made to the further provisions of this Security set forth on the reverse hereof. Such further provisions shall for all purposes have the same effect as though fully set forth at this place.

This Security shall not be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been manually signed by the Trustee under the Indenture referred to on the reverse hereof.

IN WITNESS WHEREOF, ALPHABET INC. has caused this instrument to be duly executed.

REVERSE OF SECURITY

ALPHABET INC.

4.375% Notes Due 2064

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 4.375% Notes due 2064 of the Company, limited in aggregate principal amount to €1,250,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP, ISIN or other identifying number unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of the actual number of days in the period for which interest is being calculated and the actual number of days from and including the last date on which interest was paid on the Securities of this series (or November 6, 2025 if no interest has been paid on the Securities of this series), to, but not including, the next scheduled Interest Payment Date. This payment convention is referred to as ACTUAL/ACTUAL (ICMA) as defined in the rulebook of the International Capital Markets Association. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 4.375% Notes due 2064 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of €100,000 and multiples of €1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 6, 2064 at the Company’s option in whole or in part at any time or from time to time. Prior to May 6, 2064, the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) 100% of the principal amount of the Securities to be redeemed and (ii) the sum of the present values of the remaining scheduled payments of principal and interest on the Securities to be redeemed (exclusive of interest accrued to the Redemption Date), discounted to the Redemption Date on an annual basis (ACTUAL/ACTUAL (ICMA)), at the applicable Comparable Government Bond Rate described below plus 20 basis points plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after May 6, 2064, the Company may redeem the Securities of this series by paying a Redemption Price equal to 100% of the principal amount of the Securities to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “Comparable Government Bond Rate” means, with respect to any Redemption Date, the rate per annum equal to the yield to maturity, expressed as a percentage (rounded to three decimal places, with 0.0005 being rounded upwards), on the third Business Day prior to the date fixed for redemption, calculated in accordance with customary financial practice in pricing new issues of comparable corporate debt securities paying interest on an annual basis (ACTUAL/ACTUAL (ICMA)) of the Comparable Government Bond (as defined below), assuming a price for the Comparable Government Bond (expressed as a percentage of its principal amount) equal to the Comparable Government Bond Price for such Redemption Date. “Comparable Government Bond” means, in relation to any Comparable Government Bond Rate calculation, the German government bond (Bundesanleihe) selected by an Independent Investment Banker as having an actual or interpolated maturity comparable to the remaining term of the Securities to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of euro-denominated corporate debt securities of a comparable maturity to the remaining term of such Securities. “Independent Investment Banker” means one of the Reference Government Bond Dealers selected by the Company. “Comparable Government Bond Price” means, with respect to any Redemption Date, (1) the arithmetic average of the Reference Government Bond Dealer Quotations for such Redemption Date, after excluding the highest and lowest such Reference Government Bond Dealer Quotations, or (2) if the Company obtains fewer than four such Reference Government Bond Dealer Quotations, the arithmetic average of all such quotations. “Reference Government Bond Dealer Quotations” means, with respect to each Reference Government Bond Dealer and any Redemption Date, the arithmetic average, as determined by the Company, of the bid and asked prices for the Comparable Government Bond (expressed in each case as a percentage of its principal amount) quoted in writing to the Company by such Reference Government Bond Dealer at 11:00 a.m., Central European Time (CET), on the third Business Day preceding such Redemption Date. “Reference Government Bond Dealer” means (i) each of Goldman Sachs & Co. LLC, HSBC Bank plc, J.P. Morgan Securities plc, BNP PARIBAS, Crédit Agricole Corporate and Investment Bank and Deutsche Bank AG, London Branch, or any of their affiliates that are primary European government securities dealers, and their respective successors; provided that if any of the foregoing or any of their affiliates shall cease to be a primary European government securities dealer (“Primary Dealer”), the Company shall substitute therefor another Primary Dealer and (ii) two other Primary Dealers selected by the Company.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with Clearstream or Euroclear procedures, as applicable) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of €1,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by Clearstream or Euroclear, as applicable, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of the applicable clearing system.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Subject to the exceptions and limitations set forth below, the Company will pay as additional interest on the Securities of this series such additional amounts as are necessary in order that the net payment by the Company or a paying agent of the principal, premium, if any, and interest with respect to the Securities of this series to the beneficial owner that is not a United States person (as defined below), after withholding or deduction for any present or future tax, assessment or other governmental charge imposed by the United States or a taxing authority in the United States, will not be less than the amount provided in this Security to be then due and payable; provided, however, that the foregoing obligation to pay additional amounts will not apply:

Except as specifically provided above, the Company will not be required to pay additional amounts in respect of any tax, assessment or other governmental charge. References in this Security to any payment on the Securities include the related payment of additional amounts, as applicable.

The term “United States” means the United States of America, any state thereof, and the District of Columbia, and the term “United States person” means (i) any individual who is a citizen or resident of the United States for U.S. federal income tax purposes, (ii) a corporation, partnership or other entity created or organized in or under the laws of the United States, any state thereof or the District of Columbia (other than a partnership that is not treated as a United States person for U.S. federal income tax purposes), (iii) any estate the income of which is subject to U.S. federal income taxation regardless of its source, or (iv) any trust if a U.S. court can exercise primary supervision over the administration of the trust and one or more United States persons can control all substantial trust decisions, or if a valid election is in place to treat the trust as a United States person.

If, as a result of any change in, or amendment to, the laws of the United States or the official interpretation thereof that is announced or becomes effective on or after April 29, 2025, the Company becomes or, based upon a written opinion of independent counsel selected by the Company, will become obligated to pay additional amounts as described above with respect to the Securities of this series, then the Company may at any time at its option redeem, in whole, but not in part, the Securities of this series on not less than 10 nor more than 60 days’ prior notice, at a Redemption Price equal to 100% of their principal amount, plus accrued and unpaid interest, if any, on the Securities to be redeemed to, but not including, the Redemption Date.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

ALPHABET INC., a Delaware corporation (the “Company”, which term includes any successor thereto under the Indenture referred to on the reverse hereof), for value received, hereby promises to pay to Cede & Co., or registered assigns, at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, the principal sum of FIVE HUNDRED MILLION DOLLARS ($500,000,000) (or such other principal amount as shall be set forth in the Schedule of Increases or Decreases in Note attached hereto) on November 15, 2028, in the coin or currency of the United States, and to pay interest thereon from November 6, 2025 or from the next preceding Interest Payment Date in respect of which interest has been paid or duly provided for, quarterly in arrears on February 15, May 15, August 15 and November 15 of each year, beginning on February 15, 2026 on said principal sum at said office or agency, in like coin or currency, at the rate equal to Compounded SOFR (as defined on the reverse of this Security), reset quarterly, plus 0.52%, on the basis of a 360-day year for the actual number of days elapsed during the period, until the principal hereof is paid or duly provided for or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at such rate on any overdue principal and premium and on any overdue installment of interest; provided that payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Register or by wire transfer as provided in the Indenture.

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 Security (or one or more Predecessor Securities) is registered at the close of business on the Record Date for such interest, which shall be February 1, May 1, August 1 or November 1 (whether or not a Business Day), as the case may be, next preceding such Interest Payment Date. Any such interest not so punctually paid or duly provided for will forthwith cease to be payable to the Holder on such Record Date and may either be paid to the person in whose name this Security (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 whereof shall be given to Holders of Securities of this series not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Securities of this series may be listed, and upon such notice as may be required by such exchange, all as, more fully provided in said Indenture.

REVERSE OF SECURITY

ALPHABET INC.

Floating Rates Notes Due 2028

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the Floating Rates Notes due 2028 of the Company, limited in aggregate principal amount to $500,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP numbers unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

The interest rate for any Floating Rate Interest Period (as defined below) will be Compounded SOFR as determined on the applicable Floating Rate Interest Determination Date (as defined below), plus 0.52% per annum computed on the basis of a 360-day year for the actual number of days elapsed during the period. On each Floating Rate Interest Determination Date relating to the Interest Payment Date, the calculation agent for the Securities (the “Calculation Agent”) will calculate the amount of accrued interest payable on the Securities of this series by multiplying (i) the outstanding principal amount of the Securities of this series by (ii) the product of (a) the interest rate for the relevant Floating Rate Interest Period multiplied by (b) the quotient of the actual number of calendar days in such Floating Rate Interest Period divided by 360. In no event will the interest on the Securities of this series be less than zero.

The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date (other than the Stated Maturity) falls on a day that is not a Business Day, the applicable Interest Payment Date (other than the Stated Maturity) will be the next succeeding Business Day unless that Business Day is in the next succeeding calendar month, in which case the applicable Interest Payment Date (other than the Stated Maturity) will be the immediately preceding Business Day. If any such Interest Payment Date (other than the Stated Maturity) is postponed or brought forward as described above, the interest amount will be adjusted accordingly to the number of days in the applicable period and the Holder will be entitled to more or less interest, respectively.

If the Stated Maturity falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

“Compounded SOFR” with respect to any Floating Rate Interest Period will be determined by the Calculation Agent in accordance with the following formula (and the resulting percentage will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point):

where:

“SOFR IndexStart” is the SOFR Index value for the day which is two U.S. Government Securities Business Days (as defined below) preceding the first date of the relevant Floating Rate Interest Period;

“SOFR IndexEnd” is the SOFR Index value for the day which is two U.S. Government Securities Business Days preceding the applicable Interest Payment Date relating to such Floating Rate Interest Period (or in the final Floating Rate Interest Period, preceding the Stated Maturity); and

“dc” is the number of calendar days in the relevant Observation Period (as defined below).

For purposes of determining Compounded SOFR:

“Floating Rate Interest Determination Date” means the date two U.S. Government Securities Business Days (as defined below) preceding each Interest Payment Date (or in the final Floating Rate Interest Period, preceding the Stated Maturity).

“Floating Rate Interest Period” means (i) the period from and including any Interest Payment Date (or, with respect to the initial Interest Payment Date only, from and including November 6, 2025) to but excluding the next succeeding Interest Payment Date or (ii) in the case of the last such period, from and including the Interest Payment Date immediately preceding the Stated Maturity to but excluding such Stated Maturity.

“Observation Period” means, in respect of each Floating Rate Interest Period, the period from and including the date two U.S. Government Securities Business Days (as defined below) preceding the first date in such Floating Rate Interest Period to but excluding the date two U.S. Government Securities Business Days preceding the Interest Payment Date for such Floating Rate Interest Period (or in the final Floating Rate Interest Period, preceding the Stated Maturity).

“SOFR Index” means, with respect to any U.S. Government Securities Business Day:

(1) the SOFR Index value as published by the SOFR Administrator as such index appears on the SOFR Administrator’s Website at 3:00 p.m. (New York time) on such U.S. Government Securities Business Day (the “SOFR Index Determination Time”); provided that:

(2) if a SOFR Index value does not so appear as specified in (1) above at the SOFR Index Determination Time, then: (i) if a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the “SOFR Index Unavailable Provisions” described below; or (ii) if a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to SOFR, then Compounded SOFR shall be the rate determined pursuant to the “Effects of a Benchmark Transition Event” provisions described below.

“SOFR” means the daily secured overnight financing rate as provided by the SOFR Administrator on the SOFR Administrator’s Website.

“SOFR Administrator” means the Federal Reserve Bank of New York (or a successor administrator of SOFR).

“SOFR Administrator’s Website” means the website of the Federal Reserve Bank of New York, currently at http://www.newyorkfed.org, or any successor source.

“U.S. Government Securities Business Day” means any day except for a Saturday, a Sunday or a day on which the Securities Industry and Financial Markets Association recommends that the fixed income departments of its members be closed for the entire day for purposes of trading in U.S. government securities.

Notwithstanding anything to the contrary herein, if the Company or its designee (which may be the Calculation Agent only if the Calculation Agent consents to such appointment, a successor calculation agent, an independent financial advisor or any other designee of the Company) determine on or prior to the relevant Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to determining Compounded SOFR, then the benchmark replacement provisions set forth herein will thereafter apply to all determinations of the rate of interest payable on the Securities of this series.

For the avoidance of doubt, in accordance with the benchmark replacement provisions, after a Benchmark Transition Event and its related Benchmark Replacement Date have occurred, the interest rate for each Floating Rate Interest Period will be an annual rate equal to the Benchmark Replacement plus any applicable margin.

If a SOFR IndexStart or SOFR IndexEnd is not published on the relevant Floating Rate Interest Determination Date and a Benchmark Transition Event and its related Benchmark Replacement Date have not occurred with respect to SOFR, “Compounded SOFR” means, for the relevant Floating Rate Interest Period for which such index is not available, the rate of return on a daily compounded interest investment calculated in accordance with the formula for SOFR averages, and definitions required for such formula, published on the SOFR Administrator’s Website at https://www.newyorkfed.org/markets/treasury-repo- reference-rates-information, or any successor source. For the purposes of this provision, references in the SOFR averages compounding formula and related definitions to “Calculation Period” shall be replaced with “Observation Period” and the words “that is, 30-, 90-, or 180-calendar days” shall be removed. If SOFR does not so appear for any day “i” in the Observation Period, SOFRi for such day “i” shall be SOFR published in respect of the first preceding U.S. Government Securities Business Day for which SOFR was published on the SOFR Administrator’s Website.

If the Company or the Company’s designee (which may be the Calculation Agent only if the Calculation Agent consents to such appointment, a successor calculation agent, an independent financial advisor or any other designee of the Company) determine that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred on or prior to the Reference Time in respect of any determination of the Benchmark on any date, the Benchmark Replacement will replace the then-current Benchmark for all purposes relating to the Securities of this series in respect of such determination on such date and all determinations on all subsequent dates. In connection with the implementation of a Benchmark Replacement, the Company (or the Company’s designee) will have the right to make Benchmark Replacement Conforming Changes from time to time.

Any determination, decision or election that may be made by the Company (or its designee) pursuant to the benchmark replacement provisions described above, including any determination with respect to a tenor, rate or adjustment or of the occurrence or non-occurrence of an event, circumstance or date and any decision to take or refrain from taking any action or any selection will be conclusive and binding absent manifest error, if made by the Company, will be made in the Company’s sole discretion, if made by the Company’s designee, will be made after consultation with the Company, and such designee will not make any such determination, decision or election to which the Company objects and notwithstanding anything to the contrary in the Indenture or this Security, shall become effective without consent from the Holders of Securities of this series or any other party.

“Benchmark” means, initially, Compounded SOFR, as such term is defined above; provided that if the Company or its designee (which may be the Calculation Agent only if the Calculation Agent consents to such appointment, a successor calculation agent, an independent financial advisor or any other designee of the Company) determines on or prior to the Reference Time that a Benchmark Transition Event and its related Benchmark Replacement Date have occurred with respect to Compounded SOFR (or the published daily SOFR or SOFR Index used in the calculation thereof) or the then-current Benchmark, then “Benchmark” means the applicable Benchmark Replacement.

“Benchmark Replacement” means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date:

(1) the sum of: (a) the alternate rate of interest that has been selected or recommended by the Relevant Governmental Body as the replacement for the then-current Benchmark and (b) the Benchmark Replacement Adjustment;

(2) the sum of: (a) the ISDA Fallback Rate and (b) the Benchmark Replacement Adjustment; or

(3) the sum of: (a) the alternate rate of interest that has been selected by the Company or its designee as the replacement for the then-current Benchmark giving due consideration to any industry-accepted rate of interest as a replacement for the then-current Benchmark for U.S. dollar denominated floating rate notes at such time and (b) the Benchmark Replacement Adjustment.

“Benchmark Replacement Adjustment” means the first alternative set forth in the order below that can be determined by the Company or its designee as of the Benchmark Replacement Date:

(1) the spread adjustment (which may be a positive or negative value or zero), or method for calculating or determining such spread adjustment, that has been selected or recommended by the Relevant Governmental Body for the applicable Unadjusted Benchmark Replacement;

(2) if the applicable Unadjusted Benchmark Replacement is equivalent to the ISDA Fallback Rate, the ISDA Fallback Adjustment; or

(3) the spread adjustment (which may be a positive or negative value or zero) that has been selected by the Company or its designee giving due consideration to any industry-accepted spread adjustment, or method for calculating or determining such spread adjustment, for the replacement of the then-current Benchmark with the applicable Unadjusted Benchmark Replacement for U.S. dollar- denominated floating rate notes at such time.

“Benchmark Replacement Conforming Changes” means, with respect to any Benchmark Replacement, any technical, administrative or operational changes (including changes to the definition of Floating Rate Interest Period, the timing and frequency of determining rates and making payments of interest, the rounding of amounts or tenors and other technical, administrative or operational matters) that the Company or its designee decide may be appropriate to reflect the adoption of such Benchmark Replacement in a manner substantially consistent with market practice (or, if the Company or its designee decide that adoption of any portion of such market practice is not administratively feasible or if the Company or its designee determine that no market practice for use of the Benchmark Replacement exists, in such other manner as the Company or its designee determine is reasonably practicable).

“Benchmark Replacement Date” means the earliest to occur of the following events with respect to the then-current Benchmark (including any daily published component used in the calculation thereof):

(1) in the case of clause (1) or (2) of the definition of “Benchmark Transition Event,” the later of (a) the date of the public statement or publication of information referenced therein and (b) the date on which the administrator of the Benchmark permanently or indefinitely ceases to provide the Benchmark (or such component); or (2) in the case of clause (3) of the definition of “Benchmark Transition Event,” the date of the public statement or publication of information referenced therein.

For the avoidance of doubt, if the event giving rise to the Benchmark Replacement Date occurs on the same day as, but earlier than, the Reference Time in respect of any determination, the Benchmark Replacement Date will be deemed to have occurred prior to the Reference Time for such determination.

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

(1) a public statement or publication of information by or on behalf of the administrator of the Benchmark (or such component) announcing that such administrator has ceased or will cease to provide the Benchmark (or such component), permanently or indefinitely, provided that, at the time of such statement or publication, there is no successor administrator that will continue to provide the Benchmark (or such component);

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

(3) a public statement or publication of information by the regulatory supervisor for the administrator of the Benchmark announcing that the Benchmark is no longer representative.

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

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

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

“Reference Time” with respect to any determination of the Benchmark means (1) if the Benchmark is Compounded SOFR, the SOFR Index Determination Time, as such time is defined above, and (2) if the Benchmark is not Compounded SOFR, the time determined by the Company or its designee in accordance with the Benchmark Replacement Conforming Changes.

“Relevant Governmental Body” means the Federal Reserve Board and/or the Federal Reserve Bank of New York, or a committee officially endorsed or convened by the Federal Reserve Board and/or the Federal Reserve Bank of New York or any successor thereto.

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

Neither the Trustee, nor the Calculation Agent shall be under any obligation (i) to monitor, determine or verify the unavailability or cessation of Compounded SOFR (or any other Benchmark), or whether or when there has occurred, or to give notice to any other transaction party of the occurrence of, any Benchmark Transition Event or related Benchmark Replacement Date, (ii) to select, determine or designate any Benchmark Replacement, or other successor or replacement benchmark index, or whether any conditions to the designation of such a rate or index have been satisfied, (iii) to select, determine or designate any Benchmark Replacement Adjustment, or other modifier to any replacement or successor index, or (iv) to determine whether or what Benchmark Replacement Conforming Changes are necessary or advisable, if any, in connection with any of the foregoing, including, but not limited to, adjustments as to any alternative spread thereon, the business day convention, Floating Rate Interest Determination Dates or any other relevant methodology applicable to such substitute or successor Benchmark. In connection with the foregoing, each of the Trustee, the Paying Agent and the Calculation Agent shall be entitled to conclusively rely on any determinations made by the Company or its designee without independent investigation, and none will have any liability for actions taken at the Company’s direction in connection therewith.

Neither the Trustee nor the Calculation Agent shall be liable for any inability, failure or delay on its part to perform any of its duties set forth in this Security as a result of the unavailability of Compounded SOFR or other applicable Benchmark Replacement, including as a result of any failure, inability, delay, error or inaccuracy on the part of any other transaction party in providing any direction, instruction, notice or information required or contemplated by the terms of the Indenture and reasonably required for the performance of such duties. Neither the Trustee nor the Calculation Agent shall be responsible or liable for the actions of the Company or omissions or for those of the Company’s designee, nor shall either the Trustee or the Calculation Agent be under any obligation to oversee or monitor the Company’s performance or that of the Company’s designee.

In case an Event of Default (as defined in the Indenture) with respect to the Floating Rate Notes due 2028 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of $2,000 and multiples of $1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

This Security will not be redeemable prior to maturity.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(ii) all Securities of this series not theretofore delivered to the Trustee for cancellation,

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

year consisting of twelve 30-day months, until the principal hereof is paid or duly provided for or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at such rate on any overdue principal and premium and on any overdue installment of interest; provided that payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Register or by wire transfer as provided in the Indenture.

REVERSE OF SECURITY

ALPHABET INC.

3.875% Notes Due 2028

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 3.875% Notes due 2028 of the Company, limited in aggregate principal amount to $1,000,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP numbers unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 3.875% Notes due 2028 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of $2,000 and multiples of $1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 15, 2028 at the Company’s option in whole or in part at any time or from time to time. Prior to October 15, 2028 (the “Par Call Date”), the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming that such Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 5 basis points less (b) interest accrued to the Redemption Date or (ii) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after the Par Call Date, the Company may redeem the Securities by paying a Redemption Price equal to 100% of the principal amount of the Securities of this series to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “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) (“H.15 TCM”). 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 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. 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 such 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.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC procedures) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of $2,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by DTC, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of DTC.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(ii) all Securities of this series not theretofore delivered to the Trustee for cancellation,

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered Holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and, subject to the provisions hereof, interest hereon, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

ALPHABET INC.

4.100% Notes Due 2030

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 4.100% Notes due 2030 of the Company, limited in aggregate principal amount to $2,500,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP numbers unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 4.100% Notes due 2030 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of $2,000 and multiples of $1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 15, 2030 at the Company’s option in whole or in part at any time or from time to time. Prior to October 15, 2030 (the “Par Call Date”), the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming that such Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 10 basis points less (b) interest accrued to the Redemption Date or (ii) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after the Par Call Date, the Company may redeem the Securities by paying a Redemption Price equal to 100% of the principal amount of the Securities of this series to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “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) (“H.15 TCM”). 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 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. 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 such 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.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC procedures) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of $2,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by DTC, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of DTC.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(ii) all Securities of this series not theretofore delivered to the Trustee for cancellation,

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered Holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and, subject to the provisions hereof, interest hereon, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

ALPHABET INC.

4.375% Notes Due 2032

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 4.375% Notes due 2032 of the Company, limited in aggregate principal amount to $1,250,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP numbers unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 4.375% Notes due 2032 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of $2,000 and multiples of $1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 15, 2032 at the Company’s option in whole or in part at any time or from time to time. Prior to September 15, 2032 (the “Par Call Date”), the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming that such Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 10 basis points less (b) interest accrued to the Redemption Date or (ii) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after the Par Call Date, the Company may redeem the Securities by paying a Redemption Price equal to 100% of the principal amount of the Securities of this series to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “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) (“H.15 TCM”). 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 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. 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 such 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.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC procedures) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of $2,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by DTC, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of DTC.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(ii) all Securities of this series not theretofore delivered to the Trustee for cancellation,

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

year consisting of twelve 30-day months, until the principal hereof is paid or duly provided for or made available for payment and (to the extent that the payment of such interest shall be legally enforceable) at such rate on any overdue principal and premium and on any overdue installment of interest; provided that payment of interest may be made at the option of the Company by check mailed to the address of the person entitled thereto as such address shall appear on the Register or by wire transfer as provided in the Indenture.

REVERSE OF SECURITY

ALPHABET INC.

4.700% Notes Due 2035

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 4.700% Notes due 2035 of the Company, limited in aggregate principal amount to $3,500,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP numbers unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 4.700% Notes due 2035 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of $2,000 and multiples of $1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 15, 2035 at the Company’s option in whole or in part at any time or from time to time. Prior to August 15, 2035 (the “Par Call Date”), the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming that such Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 10 basis points less (b) interest accrued to the Redemption Date or (ii) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after the Par Call Date, the Company may redeem the Securities by paying a Redemption Price equal to 100% of the principal amount of the Securities of this series to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “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) (“H.15 TCM”). 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 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. 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 such 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.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC procedures) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of $2,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by DTC, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of DTC.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(ii) all Securities of this series not theretofore delivered to the Trustee for cancellation,

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered Holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and, subject to the provisions hereof, interest hereon, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

ALPHABET INC.

5.350% Notes Due 2045

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 5.350% Notes due 2045 of the Company, limited in aggregate principal amount to $2,000,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP numbers unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 5.350% Notes due 2045 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of $2,000 and multiples of $1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 15, 2045 at the Company’s option in whole or in part at any time or from time to time. Prior to May 15, 2045 (the “Par Call Date”), the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming that such Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 15 basis points less (b) interest accrued to the Redemption Date or (ii) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after the Par Call Date, the Company may redeem the Securities by paying a Redemption Price equal to 100% of the principal amount of the Securities of this series to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “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) (“H.15 TCM”). 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 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. 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 such 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.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC procedures) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of $2,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by DTC, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of DTC.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(ii) all Securities of this series not theretofore delivered to the Trustee for cancellation,

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered Holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and, subject to the provisions hereof, interest hereon, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

ALPHABET INC.

5.450% Notes Due 2055

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 5.450% Notes due 2055 of the Company, limited in aggregate principal amount to $4,000,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP numbers unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 5.450% Notes due 2055 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in

principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of $2,000 and multiples of $1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 15, 2055 at the Company’s option in whole or in part at any time or from time to time. Prior to May 15, 2055 (the “Par Call Date”), the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming that such Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 15 basis points less (b) interest accrued to the Redemption Date or (ii) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after the Par Call Date, the Company may redeem the Securities by paying a Redemption Price equal to 100% of the principal amount of the Securities of this series to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “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) (“H.15 TCM”). 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 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. 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 such 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.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC procedures) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of $2,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by DTC, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of DTC.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(ii) all Securities of this series not theretofore delivered to the Trustee for cancellation,

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered Holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and, subject to the provisions hereof, interest hereon, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

REVERSE OF SECURITY

ALPHABET INC.

5.700% Notes Due 2075

This Security is one of a duly authorized issue of securities of the Company (hereinafter called the “Securities”) of the series hereinafter specified, all issued or to be issued under and pursuant to an Indenture, dated as of February 12, 2016 (the “Indenture”), duly executed and delivered by the Company to The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee,” which term includes any successor trustee), to which the Indenture and all indentures supplemental thereto reference is hereby made for a description of the rights, limitations of rights, obligations, duties and immunities thereunder of the Trustee, the Company and the Holders of the Securities. The Securities may be issued in one or more series, which different series may be issued in various aggregate principal amounts, may mature at different times, may bear interest (if any) at different rates, may be subject to different redemption provisions (if any), may be subject to different sinking, purchase or analogous funds (if any) and may otherwise vary as in the Indenture provided. This Security is one of a series designated as the 5.700% Notes due 2075 of the Company, limited in aggregate principal amount to $2,750,000,000; provided, however, that the Company, without notice to or consent of the Holders, may issue additional Securities of this series and thereby increase such principal amount in the future, on the same terms and conditions (except for the issue date, public offering price and, if applicable, the date from which interest accrues and the first Interest Payment Date). Any additional Securities shall be issued under one or more separate CUSIP numbers unless such additional Securities are issued pursuant to a “qualified reopening,” are otherwise treated as part of the same “issue” of debt instruments as the original series or are issued with less than a de minimis amount of original issue discount, in each case for U.S. federal income tax purposes.

Interest on the Securities of this series will be computed on the basis of a 360-day year consisting of twelve 30-day months. The Company shall pay interest on overdue principal, premium, if any, and, to the extent lawful, on overdue installments of interest at the rate per annum borne by this Security. If any Interest Payment Date, the Stated Maturity or any Redemption Date falls on a day that is not a Business Day, the related payment of principal, premium, if any, or interest will be made on the next succeeding Business Day as if it were made on the date such payment was due, and no interest will accrue on the amounts so payable for the period from and after such date to the next succeeding Business Day.

In case an Event of Default (as defined in the Indenture) with respect to the 5.700% Notes due 2075 shall have occurred and be continuing, the principal hereof and the interest accrued hereon, if any, may be declared, and upon such declaration shall become, due and payable, in the manner, with the effect and subject to the conditions provided in the Indenture.

The Indenture contains provisions that provide that the Company and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of amending any provisions of the Indenture or of modifying in any manner the rights of the Holders of the Securities of such series to be affected with the written consent of the Holders of a majority in

principal amount of the Outstanding Securities of such series affected by such amendment voting separately; provided that, without the consent of each Holder of the Securities of each series affected thereby, an amendment may not: (i) extend the Stated Maturity of the principal of, or any installment of interest on, such Holder’s Security, or reduce the principal amount thereof or the interest thereon or any premium payable upon redemption thereof, or change the Currency in which the principal of and premium, if any, or interest on such Security is denominated or payable, or reduce the amount of the principal of an Original Issue Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof, or impair the right to institute suit for the enforcement of any payment on or after the Stated Maturity thereof (or, in the case of redemption, on or after the Redemption Date), or materially adversely affect the economic terms of the Holder’s right to convert or exchange any Security as may be provided in the Indenture; (ii) reduce the percentage in principal amount of the Outstanding Securities of any series, the consent of whose Holders is required for any supplemental indenture, or the consent of whose Holders is required for any waiver of compliance with certain provisions of the Indenture or certain Defaults hereunder and their consequences provided for in the Indenture; (iii) modify any of the provisions of the Indenture governing amendments or waivers with the consent of Holders except to increase any such percentage or to provide that certain other provisions of the Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; or (iv) modify, without the written consent of the Trustee, the rights, duties or immunities of the Trustee.

It is also provided in the Indenture that, subject to certain conditions and exceptions, the Holders of a majority in aggregate principal amount of a series of Securities at the time Outstanding may on behalf of the Holders of all of the Securities of such series waive any past Default or Event of Default hereunder and its consequences except a Default in the payment of interest or any premium on or the principal of the Securities of such series or a Default in respect of a covenant or provision of the Indenture that cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series. Upon any such waiver, the Company, the Trustee and the Holders of the Securities of such series shall be restored to their former positions and rights under the Indenture, respectively; provided that no such waiver shall extend to any subsequent or other Default or Event of Default or impair any right consequent thereon.

No reference herein to the Indenture and no provision of this Security or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and interest on this Security in the manner, at the place, at the respective times, at the rate and in the coin or currency herein prescribed.

The Securities of this series will be issued in fully registered form without coupons in minimum denominations of $2,000 and multiples of $1,000 in excess thereof and are transferable and exchangeable at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, and in the manner and subject to the limitations provided in the Indenture.

The Securities of this series are redeemable prior to November 15, 2075 at the Company’s option in whole or in part at any time or from time to time. Prior to May 15, 2075 (the “Par Call Date”), the Company may redeem the Securities of this series by paying a Redemption Price equal to the greater of (i) (a) the sum of the present values of the remaining scheduled payments of principal and interest thereon discounted to the Redemption Date (assuming that such Securities matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day months) at the applicable Treasury Rate plus 20 basis points less (b) interest accrued to the Redemption Date or (ii) 100% of the principal amount of the Securities to be redeemed, plus, in either case, accrued and unpaid interest, if any, to, but not including, the Redemption Date. On or after the Par Call Date, the Company may redeem the Securities by paying a Redemption Price equal to 100% of the principal amount of the Securities of this series to be redeemed plus accrued and unpaid interest, if any, to, but not including, the Redemption Date.

For the purposes of determining the Redemption Price, “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) (“H.15 TCM”). 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 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. 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 such 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.

Notice of redemption will be mailed or electronically delivered (or otherwise transmitted in accordance with DTC procedures) at least 10 but not more than 60 days before the Redemption Date to each holder of record of the Securities of this series. Notice of any redemption of the Securities of this series in connection with a transaction or an event may, at the Company’s discretion, be given prior to the completion or the occurrence thereof. Any redemption or notice may, at the Company’s discretion, be subject to one or more conditions precedent, including, but not limited to, completion or occurrence of a related transaction or event. At the Company’s discretion, the Redemption Date may be delayed until such time as any or all such conditions shall be satisfied, or such redemption may not occur and such notice may be rescinded in the event that any or all such conditions shall not have been satisfied by the Redemption Date, or by the Redemption Date as so delayed. The Company will provide written notice to the Trustee prior to the close of business two Business Days prior to the Redemption Date if any such redemption has been rescinded or delayed, and upon receipt the Trustee will provide such notice to each holder of the Securities to be redeemed in the same manner in which the notice of redemption was given.

No Securities of this series of a principal amount of $2,000 or less will be redeemed in part. If this Security is to be redeemed in part only, the notice of redemption that relates to this Security will state the portion of the principal amount of this Security to be redeemed. A new security in a principal amount equal to the unredeemed portion of this Security will be issued in the name of the holder of the Security upon surrender for cancellation of the original Security. For so long as the Securities of this series are held by DTC, the redemption and the selection of Securities to be redeemed shall be in accordance with the policies and procedures of DTC.

Unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date, interest will cease to accrue on the Securities of this series or portions thereof called for redemption.

Solely with respect to Securities of this series, Section 12.02 of the Indenture is amended and restated as follows:

“This Indenture, with respect to the Securities of this series, shall, upon Company Order, cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the Securities expressly provided for in the Indenture and rights to receive payments of principal of, premium, if any, and interest on, such Securities) and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of the Indenture, when,

(a) either:

(i) all Securities of this series theretofore authenticated and delivered (other than (A) Securities that have been destroyed, lost or stolen and that have been replaced or paid as provided in Section 3.07 of the Indenture and (B) Securities for whose payment money has theretofore been deposited in trust or segregated and held in trust by the Company and thereafter repaid to the Company or discharged from such trust, as provided in Section 6.03 of the Indenture) have been delivered to the Trustee for cancellation; or

(ii) all Securities of this series not theretofore delivered to the Trustee for cancellation,

(A) have become due and payable, or

(B) shall become due and payable at their Stated Maturity within one year, or

(C) are to be called for redemption within one year under arrangements satisfactory to the Trustee for the giving of notice by the Trustee in the name, and at the expense, of the Company,

and in the case of (A), (B) or (C) above, the Company has deposited or caused to be deposited with the Trustee or Paying Agent as trust funds in trust (i) funds in trust for the purpose an amount in the Currency in which the Securities are denominated, (ii) Government Obligations that through the payment of interest and principal in respect thereof in accordance with their terms shall provide, not later than one day before the due date of any payment, money in an amount, or (iii) a combination of (i) and (ii), sufficient to pay and discharge the entire Indebtedness on such Securities for principal and premium, if any, and interest to the date of such deposit (in the case of Securities that have become due and payable) or to the Stated Maturity or Redemption Date, as the case may be; provided, however, in the event a petition for relief under the Bankruptcy Code or any applicable state bankruptcy, insolvency or other similar law, is filed with respect to the Company within 91 days after the deposit and the Trustee is required to return the moneys then on deposit with the Trustee to the Company, the obligations of the Company under this Indenture with respect to such Securities shall not be deemed terminated or discharged;

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company; and

(c) the Company has delivered to the Trustee an Officer’s Certificate and an Opinion of Counsel each stating that all conditions precedent herein provided for relating to the satisfaction and discharge of this Indenture with respect to such series have been complied with. Notwithstanding the satisfaction and discharge of this Indenture, the obligations of the Company to the Trustee under Section 11.01 of the Indenture and, if money shall have been deposited with the Trustee pursuant to subclause (B) of clause (a)(i) above, the obligations of the Trustee under Section 12.07 and Section 6.03(e) of the Indenture shall survive such satisfaction and discharge.”

Upon due presentment for registration of transfer of this Security at the office or agency of the Company maintained for such purpose, which shall initially be the Corporate Trust Office of the Trustee, a new Security or Securities of authorized denominations for an equal aggregate principal amount shall be issued to the transferee in exchange therefor, subject to the limitations provided in the Indenture, without charge except for any tax or other governmental charge imposed in connection therewith.

The Company, the Trustee and any agent of the Company or the Trustee may deem and treat the registered Holder hereof as the absolute owner of this Security (whether or not this Security shall be overdue and notwithstanding any notation of ownership or other writing hereon), for the purpose of receiving payment of, or on account of, the principal hereof and, subject to the provisions hereof, interest hereon, and for all other purposes, and neither the Company nor the Trustee nor any agent of the Company or the Trustee shall be affected by any notice to the contrary.

No recourse under or upon any obligation, covenant or agreement contained in the Indenture or any indenture supplemental thereto or in any Security, or because of any indebtedness evidenced thereby, shall be had against any incorporator as such, or against any past, present or future stockholder, officer, director or employee, as such, of the Company or of any successor, either directly or through the Company or any successor, under any rule of law, statute or constitutional provision or by the enforcement of any assessment or by any legal or equitable proceeding or otherwise, all such liability being expressly waived and released by the acceptance hereof and as part of the consideration for the issue hereof.

Terms used herein that are defined in the Indenture and not otherwise defined herein shall have the respective meanings assigned thereto in the Indenture.

The laws of the State of New York (without regard to conflicts of laws principles thereof) shall govern this Security.

We note that by statute, the law of the State of New York provides that a judgment or decree rendered in a currency other than the currency of the United States shall be converted into U.S. dollars at the rate of exchange prevailing on the date of entry of the judgment or decree. There is no corresponding Federal statute and no controlling Federal court decision on this issue. Accordingly, we express no opinion as to whether a Federal court would award a judgment in a currency other than U.S. dollars or, if it did so, whether it would order conversion of the judgment into U.S. dollars.

The foregoing opinion is limited to the law of the State of New York and the General Corporation Law of the State of Delaware.
