(REVERSE OF SECURITY)

1.513% Notes due 2039

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture, dated as of November 8, 2000, as supplemented, between the Company and The Bank of New York Mellon Trust Company, N.A. (successor to JPMorgan Chase Bank, N.A., formerly The Chase Manhattan Bank), as Trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture) and an Officer’s Certificate relating to the Securities, dated as of August 14, 2019 (together with the Indenture, herein called the “Indenture”, which term shall have the meaning assigned to it in the Indenture), and reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, limited initially in aggregate principal amount to ¥5,900,000,000 (which amount may be increased at the option of the Company as provided below if in the future it determines that it may wish to sell additional Securities of this series).

The Company may from time to time, without consent of the existing Holders, create and issue additional Securities of this series (the “Additional Securities”) having the same terms and conditions as the Securities of this series in all respects, except for the issue date, issue price and, under some circumstances, the first payment of interest thereon. Such Additional Securities, at the Company’s determination and in accordance with the provisions of the Indenture, will be consolidated with and form a single series with the previously outstanding Securities of this series for U.S. federal income tax purposes and for all purposes under the Indenture, including,

without limitation, amendments, waivers and redemptions. The aggregate principal amount of the Additional Securities, if any, of this series shall be unlimited.

The Securities of this series are subject to redemption as follows:

If, as a result of any change in, or amendment to, the laws (or any regulations or rulings promulgated under the laws) of the United States (or any political subdivision or taxing authority of or in the United States), or any change in, or amendments to, an official position regarding the application or interpretation of such laws, regulations or rulings, which change or amendment is announced or becomes effective on or after August 6, 2019, the Company determines, based upon its receipt of a written opinion of independent counsel selected by the Company, that the Company will become obligated to pay Additional Amounts, as described in Section 1011 of the Indenture, with respect to the Securities of this series, then the Company may at its option redeem, in whole, but not in part, the Securities of this series on not less than 30 nor more than 60 days’ prior notice, at a redemption price equal to 100% of their principal amount, together with interest accrued but unpaid on those Securities to the date fixed for redemption.

The Securities of this series are subject to repurchase at the option of the Holder as follows: If a Change of Control Triggering Event (as defined below) occurs, unless the Company has redeemed the Securities for tax reasons, it will be required to make an offer to each Holder to repurchase all or, at the Holder’s option, any part (equal to ¥100,000,000 or any multiple of ¥10,000,000 in excess thereof) of each Holder’s Securities pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, the Company will be required to offer to repurchase each Holder’s Securities in cash at a price equal to 101% of the aggregate principal amount of Securities repurchased, plus any accrued and unpaid interest on the

- 2 -

Securities repurchased to, but not including, the date of repurchase (the “Change of Control Payment”).

Within 30 days following any Change of Control Triggering Event, or at the Company’s option, prior to any Change of Control (as defined below), but after the public announcement of a pending Change of Control, the Company will be required to send to each Holder of Securities, a notice describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase such Securities on the date specified in the notice, which date will be no earlier than 15 days and no later than 60 days from the date such notice is transmitted (a “Change of Control Payment Date”). The notice, if transmitted prior to the date of consummation of the Change of Control, will state that the Change of Control Offer is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date.

On the Change of Control Payment Date, the Company will be required, to the extent lawful, to:

The Paying Agent will be required to promptly deliver, to each Holder who properly tendered Securities, the Change of Control Payment for such Securities, and the Trustee will be required to promptly authenticate and mail (or cause to be transferred by book entry) to each such Holder a new Security equal in principal amount to any unpurchased portion of the

- 3 -

Securities surrendered, if any; provided that each new Security will be in a principal amount of ¥100,000,000 or any multiple of ¥10,000,000 in excess thereof.

The Company will not be required to make a Change of Control Offer upon a Change of Control Triggering Event if a third party makes an offer to purchase the Securities in the manner, at the times and otherwise in compliance with the requirements for an offer to purchase made by the Company and such third party purchases all Securities properly tendered and not withdrawn under its offer. In the event that such third party terminates or defaults its offer, the Company will be required to make a Change of Control Offer treating the date of such termination or default as though it were the date of the Change of Control Triggering Event.

The Company will not repurchase any Securities if there has occurred and is continuing on the Change of Control Payment Date an Event of Default other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

Except as provided in the last sentence of the next paragraph, the Company may only make an amendment or modification to the provisions obligating it to repurchase the Securities upon a Change of Control Triggering Event which adversely affects the interest of any Holder, with the consent of each Holder of the series of Securities to be affected by such amendment or modification.

The Company will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Securities as a result of a Change of Control Triggering Event. To the extent that the provision of any such securities laws or regulations conflicts with the Change of Control Offer provisions of this Security, the Company will comply with those securities laws and regulations and will not be deemed to have breached

- 4 -

its obligations under the Change of Control Offer provisions of this Security by virtue of not complying with the Change of Control Offer provisions as a result of any such conflict.

For these purposes, the following terms will be applicable:

“Change of Control” means the occurrence of any one of the following: (1) the direct or indirect sale, lease, transfer, conveyance or other disposition (other than by way of merger, amalgamation, arrangement or consolidation), in one or a series of related transactions, of all or substantially all of the Company’s properties or assets and those of its subsidiaries, taken as a whole, to one or more persons, other than to the Company or one of its subsidiaries; (2) the first day on which a majority of the members of the Company’s board of directors is not composed of Continuing Directors (as defined below); (3) the consummation of any transaction including, without limitation, any merger, amalgamation, arrangement or consolidation the result of which is that any person becomes the beneficial owner, directly or indirectly, of more than 50% of the Company’s Voting Stock, measured by voting power rather than number of shares; (4) the Company consolidates with, or merges with or into, any person, or any person consolidates with, or merges with or into, the Company, in any such event pursuant to a transaction in which any of the outstanding Voting Stock of the Company or of such other person is converted into or exchanged for cash, securities or other property, other than any such transaction where the shares of the Company’s Voting Stock outstanding immediately prior to such transaction constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person or any direct or indirect parent company of the surviving person immediately after giving effect to such transaction; or (5) the adoption of a plan relating to the Company’s liquidation or dissolution (other than its liquidation into a newly formed holding company). Notwithstanding the foregoing, a transaction described in clause (3) above will not be deemed to involve a

“Change of Control Triggering Event” means the Securities cease to be rated Investment Grade by each of the Rating Agencies on any date during the 60-day period (the “Trigger Period”) following the earlier date of (1) the first public announcement of the Change of Control or the Company’s intention to effect a Change of Control and (2) the consummation of such Change of Control, which Trigger Period will be extended following consummation of a Change of Control for so long as the rating of the Securities is under publicly announced consideration for possible downgrade by any of the Rating Agencies. Unless at least one Rating Agency is providing a rating for the long-term unsecured debt of the Company at the commencement of any Trigger Period, the Securities will be deemed to have ceased to be rated Investment Grade during that Trigger Period. Notwithstanding the foregoing, no Change of Control Triggering

- 6 -

Event will be deemed to have occurred in connection with any particular Change of Control unless and until such Change of Control has actually been consummated.

“Investment Grade” means a rating equal to or higher than Baa3 (or the equivalent) by Moody’s or BBB- (or the equivalent) by S&P, and the equivalent investment grade credit rating from any replacement Rating Agency or Rating Agencies selected by the Company.

No sinking fund is provided for the Securities of this series.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

Any such consent or

- 8 -

waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security issued upon the registration of transfer hereof or in exchange therefor or in lieu hereof, whether or not notation of such consent or waiver is made upon this Security.

As provided in and subject to the provisions of the Indenture, the Holder of this Security shall not have the right to institute any proceeding with respect to the Indenture, or for the appointment of a receiver or trustee, or for any other remedy thereunder, unless such Holder shall have previously given the Trustee written notice of a continuing Event of Default with respect to the Securities of this series, the Holders of not less than 25% in principal amount of the Securities of this series at the time Outstanding shall have made written request to the Trustee to institute proceedings in respect of such Event of Default as Trustee and offered the Trustee indemnity reasonably satisfactory to it, and the Trustee shall not have received from the Holders of a majority in principal amount of Securities of this series at the time Outstanding a direction inconsistent with such request, and shall have failed to institute any such proceeding, for 60 days after receipt of such notice, request and offer of indemnity. The foregoing shall not apply to any suit instituted by the Holder of this Security for the enforcement of any payment of principal hereof or any premium or interest hereon on or after the respective due dates expressed herein.

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 any premium and interest on this Security at the times, place and rate, and in the coin or currency, herein prescribed.
