Each of the provisions of the Underwriting Agreement is incorporated herein by reference in its entirety, and shall be deemed to be a part of this Agreement to the same extent as if such provisions had been set forth in full herein; and each of the representations and warranties set forth therein shall be deemed to have been made at and as of the date of this Pricing Agreement, except that each representation and warranty that refers to the Pricing Disclosure Package or the Prospectus in Section 2 of the Underwriting Agreement shall be deemed to be a representation or warranty as of the date of the Underwriting Agreement in relation to the Pricing Disclosure Package or Prospectus, and also a representation and warranty as of the date of this Pricing Agreement in relation to the Pricing Disclosure Package or the Prospectus as amended or supplemented relating to the Designated Securities which are the subject of this Pricing Agreement. Each reference to the Representatives herein and in the provisions of the Underwriting Agreement so incorporated by reference shall be deemed to refer to you. Unless otherwise defined herein, terms defined in the Underwriting Agreement are used herein as therein defined. The Representatives designated to act on behalf of the Representatives and on behalf of each of the Underwriters of the Designated Securities pursuant to Section 13 of the Underwriting Agreement and the address of the Representatives referred to in such Section 13 are set forth at the end of Schedule II hereto.

An amendment to the Registration Statement, or a supplement to the Prospectus, as the case may be, relating to the Designated Securities, in the form heretofore delivered to you is now proposed to be filed with the Commission.

Subject to the terms and conditions set forth herein and in the Underwriting Agreement incorporated herein by reference, the Company agrees to issue and sell to the Underwriters, and the Underwriters agree to purchase from the Company, severally and not jointly, at the time and place and at the purchase price to the Underwriters set forth in Schedule II-A, Schedule II-B and Schedule II-C hereto, as applicable, the principal amount of Securities set forth opposite the name of such Underwriters in Schedule I hereto.

If the foregoing is in accordance with your understanding, please sign and return to us three counterparts hereof, and upon acceptance hereof by you, this letter and such acceptance hereof, including the provisions of the Underwriting Agreement incorporated herein by reference, shall constitute a binding agreement between you and the Company.

*Note: A securities rating is not a recommendation to buy, sell or hold securities and may be subject to revision or withdrawal at any time.

** We expect that delivery of the notes will be made against payment therefor on or about June 7, 2018, which is the 5th Tokyo business day following the date of this term sheet (such settlement cycle being referred to as “T+5”). Under the E.U. Central Securities Depositaries Regulation, trades in the secondary market generally are required to settle in two London business days unless the parties to such trade expressly agree otherwise. Also, under Rule 15c6-1 under the Securities Exchange Act of 1934, as amended, trades in the secondary market generally are required to settle in two New York business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade the notes earlier than the 2^nd London business day or the 2^nd New York business day before June 7, 2018 will be required, by virtue of the fact that the notes initially will settle T+5, to specify an alternative settlement cycle at the time of any such trade to prevent failed settlement, and so should consult their own advisors.

The 2025 Notes, the 2028 Notes and the 2030 Notes are being offered separately, and are not part of a unit. The closing of each series of notes is not conditioned on the closing of any other series of notes.

MiFID II professionals/ECPs-only / No PRIIPs KID – Manufacturer target market (MIFID II product governance) is eligible counterparties and professional clients only (all distribution channels). No PRIIPs key information document (KID) has been prepared as not available to retail in EEA.

The Issuer has filed a registration statement (including a prospectus relating to each series of notes and the preliminary prospectus supplement relating to the 2025 Notes and the 2028 Notes) with the SEC for the offering to which this communication relates. Before you invest, you should read the prospectus and the preliminary prospectus supplement relating to the securities described above in that registration statement and other documents the Issuer has filed with the SEC for more complete information about the Issuer and this offering. You may get these documents for free by visiting EDGAR on the SEC Web site at www.sec.gov. Alternatively, the Issuer, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by calling Merrill Lynch International at ###-###-#### (toll free), MUFG Securities EMEA plc at +44-20-7577-2206 or by calling SMBC Nikko Securities America, Inc. at ###-###-####.
