REVERSE OF SECURITY

ALPHABET INC.

4.000% 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 4.000% Notes due 2030 of the Company, limited in aggregate principal amount to $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 4.000% 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 May 15, 2030 at the Company’s option in whole or in part at any time or from time to time. Prior to April 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 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.

4.500% 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 4.500% Notes due 2035 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 4.500% 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 May 15, 2035 at the Company’s option in whole or in part at any time or from time to time. Prior to February 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., 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 May 15, 2055, in the coin or currency of the United States, and to pay interest thereon from May 1, 2025 or from the next preceding Interest Payment Date in respect of which interest has been paid or duly provided for, semi-annually in arrears on May 15 and November 15 of each year, beginning on November 15, 2025 on said principal sum at said office or agency, in like coin or currency, at the rate of 5.250% per annum, on the basis of a 360-day

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.

5.250% 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 5.250% Notes due 2055 of the Company, limited in aggregate principal amount to $1,500,000,000; 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 5.250% 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 May 15, 2055 at the Company’s option in whole or in part at any time or from time to time. Prior to November 15, 2054 (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;

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.

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.

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 May 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.

5.300% Notes Due 2065

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 5.300% Notes due 2065 of the Company, limited in aggregate principal amount to $1,500,000,000; 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 5.300% Notes due 2065 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 May 15, 2065 at the Company’s option in whole or in part at any time or from time to time. Prior to November 15, 2064 (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.

Mountain View, CA 94043

Ladies and Gentlemen:

We have acted as special counsel to Alphabet Inc., a Delaware corporation (the “Company”), in connection with its offering pursuant to a registration statement on Form S-3 (No. 333-286752) (the “Registration Statement”) and the prospectus, dated April 25, 2025, as supplemented by the prospectus supplement, dated April 28, 2025 (together, the “Prospectus”), of:

The Securities were issued pursuant to an indenture dated as of February 12, 2016 (the “Indenture”), between the Company and The Bank of New York Mellon Trust Company, N.A., as Trustee (the “Trustee”).

In arriving at the opinion expressed below, we have reviewed the following documents:

Alphabet Inc., p. 2

In addition, we have reviewed the originals or copies certified or otherwise identified to our satisfaction of all such corporate records of the Company and such other documents, and we have made such investigations of law, as we have deemed appropriate as a basis for the opinion expressed below.

In rendering the opinion expressed below, we have assumed the authenticity of all documents submitted to us as originals and the conformity to the originals of all documents submitted to us as copies. In addition, we have assumed and have not verified the accuracy as to factual matters of each document we have reviewed.

Based on the foregoing, and subject to the further assumptions and qualifications set forth below, it is our opinion that the Securities have been validly issued by the Company and are the valid, binding and enforceable obligations of the Company, entitled to the benefits of the Indenture.

Insofar as the foregoing opinion relates to the valid existence and good standing of the Company, it is based solely on confirmation from public officials. Insofar as the foregoing opinion relates to the validity, binding effect or enforceability of any agreement or obligation of the Company, (a) we have assumed that the Company and each other party to such agreement or obligation has satisfied those legal requirements that are applicable to it to the extent necessary to make such agreement or obligation enforceable against it (except that no such assumption is made as to the Company regarding matters of the federal law of the United States of America, the law of the State of New York or the General Corporation Law of the State of Delaware that in our experience normally would be applicable to general business entities with respect to such agreement or obligation), (b) we express no opinion with respect to the effect of any mandatory choice of law rules and (c) such opinion is subject to applicable bankruptcy, insolvency and similar laws affecting creditors’ rights generally and to general principles of equity.

Alphabet Inc., p. 3

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

We hereby consent to the use of our name in the Prospectus under the heading “Legal Matters” as counsel for the Company who has passed on the validity of the Securities and to the filing of this opinion letter as Exhibit 5.1 to the Company’s Current Report on Form 8-K dated May 1, 2025. In giving such consent, we do not thereby admit that we are within the category of persons whose consent is required under Section 7 of the Securities Act of 1933, as amended or the rules and regulations of the Securities and Exchange Commission thereunder.

The opinion expressed herein is rendered on and as of the date hereof, and we assume no obligation to advise you or any other person, or to make any investigations as to any legal developments or factual matters arising subsequent to the date hereof that might affect the opinion expressed herein.
