If the firm or firms listed in Schedule II hereto include only the firm or firms listed as “Representatives” in Schedule I hereto, then the terms “Underwriters” and “Representatives” as used herein shall each be deemed to refer to such firm or firms.

2. Representations and Warranties of Issuer and Japan. Issuer and Japan severally represent and warrant to and agree with the several Underwriters that:

(a) Issuer and Japan have filed with the Securities and Exchange Commission (the “Commission”) Registration Statement[s] [No. - and] No. 333- , [each of] which has become effective, for the registration under the Securities Act of 1933, as amended (the “Act”) of the Securities.

Registration Statement[s] [No. - and] No. 333- , including the exhibits thereto and the information incorporated by reference therein, as amended at the date of this Agreement, [is] [are] hereinafter [collectively] called the “Registration Statement”. The prospectus included in Registration Statement No. 333- , including all information incorporated by reference therein, is hereinafter called the “Base Prospectus”. The supplemented form of prospectus relating to the Securities, in the form in which it shall be filed with the Commission pursuant to Rule 424(b) (including the Base Prospectus as so supplemented) is hereinafter called the “Final Prospectus”. The prospectus supplement included in the Final Prospectus is hereinafter called the “Prospectus Supplement.” Any preliminary form of the Final Prospectus which has heretofore been filed pursuant to Rule 424(b) is hereinafter called a “Preliminary Final Prospectus”. Any reference herein to the Registration Statement, Base Prospectus, the Final Prospectus, any Preliminary Final Prospectus, or any amendment or supplement thereto, shall be deemed to refer to and include the information contained in any annual report (an “Annual Report”) on Form 18-K or amendment thereto of Issuer or Japan under the Securities Exchange Act of 1934, as amended (the “Exchange Act”) which is incorporated therein by reference.

(b) The Registration Statement, the Final Prospectus and each amendment or supplement thereto relevant to the Securities, as of their respective effective or issue dates, conformed or will conform, as the case may be, in all respects with the applicable requirements of the Act, including the rules and regulations of the Commission thereunder, and neither such Registration Statement nor the Final Prospectus nor any amendment or supplement thereto, as of their respective effective or issue dates, contained or will contain, as the case may be, any untrue statement of a material fact or omitted or will omit, as the case may be, to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; provided, however, that neither Issuer nor Japan makes any representations or warranties as to the information contained in or omitted from the Registration Statement or the Final Prospectus or any amendment thereof or supplement thereto relevant to the Securities in reliance upon and in conformity with information furnished in writing to Issuer or Japan by or on behalf of any Underwriter through the Representative[s] specifically for use in connection with the preparation of the Registration Statement and the Final Prospectus. Each Underwriter hereby furnishes to Issuer and Japan in writing through the Representative[s] specifically for use with reference to such Underwriter in the preparation of the Registration Statement and the Final Prospectus, or any amendment thereof or supplement thereto relevant to the Securities, the statements in the Final Prospectus specified in Schedule I hereto.

(d) (i) At the earliest time that Issuer, Japan or another offering participant made a bona fide offer (within the meaning of Rule 164(h)(2) under the Act) and (ii) as of the date hereof, neither Issuer nor Japan was or is an “ineligible issuer” as defined in Rule 405 under the Act, without taking into account of any determination by the Commission pursuant to such Rule that it is not necessary that Issuer or Japan be considered an “ineligible issuer”.

(e) Neither Issuer nor Japan has made or will make any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus without the prior consent of the Representative[s]; Schedule III hereto is a complete list of Issuer Free Writing Prospectuses for which Issuer and Japan have received such consent; and Issuer and Japan have complied and will comply with the requirements of Rule 433 under the Act applicable to any Issuer Free Writing Prospectus (including the Term Sheet), including timely filing with the Commission or retention where required and legending.

(f) Each of Issuer and Japan represents, warrants and undertakes to the Underwriters that it has not issued and will not issue, without the prior consent of the stabilization agent, any communication to which MAR 2.3.5(1) of the price stabilizing rules made under section 144(1) of the Financial Services and Markets Xxx 0000 of the United Kingdom of those rules applies unless that communication adequately discloses that stabilizing action may take place in relation to such issue and complies with MAR 2.3.5(1)(a)-(e) of those rules.

5. Covenants of Issuer and Japan.

(a) Issuer and Japan severally covenant and agree with the several Underwriters that:

(i) Issuer and Japan will advise the Representative[s] promptly of any proposal to amend or supplement the Registration Statement or the Base Prospectus, so long as delivery of a prospectus

relating to the Securities by an Underwriter or dealer may be required under the Act, and will not effect such amendment or supplementation, whether by filing an amendment pursuant to the Act, the Exchange Act or otherwise, without the consent of the Representative[s]. Subject to the foregoing sentence, Issuer and Japan (A) will cause the Final Prospectus to be promptly transmitted for filing with the Commission pursuant to Rule 424(b) or will otherwise cause the Final Prospectus to be promptly filed with the Commission pursuant to said Rule, (B) will cause an amendment to the most recent Annual Report of Issuer to be filed with the Commission containing any exhibits required, in connection with the Securities, pursuant to the Act, including but not limited to an opinion of counsel for Issuer and Japan as to the validity of the Securities and guarantee thereof and a list of the Underwriters’ names and addresses, and (C) will cause the Term Sheet and all other material (if any) required to be filed by Issuer or Japan with the Commission pursuant to Rule 433(d) under the Act (“Rule 433(d)”) to be promptly transmitted for filing with the Commission pursuant to said Rule or will otherwise cause the Term Sheet and such other material (if any) to be promptly filed with the Commission pursuant to said Rule. Issuer and Japan will promptly advise the Representative[s] (A) when the Final Prospectus shall have been mailed for filing to, or filed with, the Commission pursuant to Rule 424(b), (B) when such amendment to the most recent Annual Report shall have been or filed with the Commission, (C) when any amendment to the Registration Statement relating to the Securities shall have become effective, (D) of any request by the Commission for any amendment (relevant to the Securities) of the Registration Statement, or amendment of or supplement to the Final Prospectus, or for any additional information and (E) of the institution by the Commission of any stop order proceedings suspending the effectiveness of the Registration Statement. Issuer and Japan will use their best efforts to prevent the issuance of any such stop order and to obtain as soon as possible its lifting, if issued.

(ii) If at any time when a prospectus relating to the Securities (or in lieu thereof, the notice referred to in Rule 173(a) under the Act) is required to be delivered under the Act, any event occurs as a result of which the Final Prospectus as then amended or supplemented would include an untrue statement of a material fact, or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it is necessary at any time to amend or supplement the Final Prospectus to comply with the Act, Issuer and Japan promptly will prepare and file with the Commission, subject to the first sentence of subparagraph (i) of this paragraph (a), whether by filing documents pursuant to the Act, the Exchange Act or otherwise, an amendment or supplement, which will correct such statement or omission or an amendment or supplement which will effect such compliance.

(iii) Issuer and Japan will furnish to the Representative[s] copies of the Registration Statement and each amendment thereto which shall become effective on or prior to the Closing Date (one of which will include all exhibits), and, so long as delivery of a prospectus by an Underwriter or dealer may be required by the Act, any Preliminary Final Prospectus and the Final Prospectus, and all amendments and supplements to such documents, in each case as soon as available and in such reasonable quantities as the Representative[s] request.

(iv) Issuer and Japan will use their best efforts to arrange for the qualification of the Securities, including the guarantee thereof, for sale under the laws of such jurisdictions as the Representative[s] may reasonably designate and to continue such qualifications in effect so long as required for the distribution of the Securities; provided, however, that in connection therewith Issuer shall not be required to qualify as a foreign corporation and neither Issuer nor Japan shall be required to file a general consent to the service of process in any such jurisdiction.

(v) If specified in Schedule I hereto, Issuer and Japan will make prompt application for the listing of the Securities on the New York Stock Exchange and for the registration thereof under the Exchange Act, or for the listing of the Securities on the London Stock Exchange or on the Luxembourg Stock Exchange, and will use their best efforts to cause such listing and/or registration to become effective. For the avoidance of doubt, in the event that the Securities are listed on the London Stock Exchange or

the Luxembourg Stock Exchange, Issuer and Japan are not hereby obligated to maintain a listing of the Securities on such Exchange following the effectiveness of such listing.

(vi) If at any time following issuance of an Issuer Free Writing Prospectus (including the Term Sheet) any event occurred or occurs as a result of which such Issuer Free Writing Prospectus would conflict with the information in the Registration Statement, the Base Prospectus, any Preliminary Final Prospectus or the Final Prospectus or would include an untrue statement of a material fact or omit to state any material fact necessary in order to make the statements therein, in the light of the circumstances then prevailing, not misleading, Issuer and Japan will give prompt notice thereof to the Representative[s] and, if requested by the Representative[s], will prepare and furnish without charge to each Underwriter an Issuer Free Writing Prospectus or other document which will correct such conflict, statement or omission; provided, however, that this covenant shall not apply to any statements or omissions in an Issuer Free Writing Prospectus made in reliance upon and in conformity with information furnished in writing to Issuer and Japan by any Underwriter through the Representative[s] expressly for use therein.

(b) Issuer covenants and agrees with the several Underwriters that:

Issuer will pay all expenses authorized by it (including reasonable fees and disbursements of counsel) incurred in connection with the qualification of the Securities for sale and the determination of their eligibility for investment under the laws of such jurisdictions as the Representative[s] may reasonably designate and the printing of memoranda relating thereto. Issuer will pay all fees and expenses of the legal counsels for Issuer and the Underwriters in connection with the issuance and offering of the Securities, the fees and expenses of the Fiscal Agent and other agents named in the Fiscal Agency Agreement and the cost and expenses in connection with tombstone advertisement (if any).

(ii) For its first full fiscal year commencing after the date of this Agreement and as soon as practicable after the termination of such fiscal year, Issuer will (A) file an earnings statement with the Commission as part of its Annual Report on Form 18-K in accordance with the procedures set forth in the no-action letter, dated August 3, 1994, of the Commission regarding Japan, The Japan Development Bank, the Export-Import Bank of Japan, Japan Finance Corporation for Municipal Enterprises, and the Metropolis of Tokyo or (B) otherwise make available to the holders of the Securities an equivalent earnings statement.

(iii) Issuer will pay to the Representative[s], on behalf of the Underwriters, on the Closing Date, the sum specified in Schedule I, in lieu of reimbursement of any of the Underwriters’ expenses (including any costs and expenses mentioned in Section 5(b)(i) paid by Underwriters and Underwriters’ out-of-pocket expenses, if any).

(i) It will guarantee unconditionally and irrevocably the payment of the principal of, interest on and any additional amounts of the Securities, and it will cause its guarantee in substantially the form set forth as an exhibit to the Fiscal Agency Agreement to be endorsed on each Security and to be validly executed on behalf of Japan.

(d) The Representative[s] shall have received an opinion of Xxxxxxxx & Xxxxxxxx LLP, United States counsel for the Underwriters, dated the Closing Date, with respect to the Securities, governmental approvals, the guarantee of the Securities by Japan, the Fiscal Agency Agreement, this Agreement and other related matters as the Representative[s] may reasonably require, and Issuer and Japan shall have furnished to such counsel such documents as they request for the purpose of enabling them to pass upon such matters. In rendering such opinion, such counsel may rely as to all matters governed by Japanese law upon the opinion of Japanese counsel for Issuer and Japan referred to above.

(a) Issuer and Japan each will indemnify and hold harmless each Underwriter and each person, if any, who controls any Underwriter within the meaning of the Act against any losses, claims, damages or liabilities, joint or several, to which such Underwriter or such controlling person may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Base Prospectus, any Preliminary Final Prospectus, the Final

Prospectus, or any amendment or supplement thereto, or any Issuer Free Writing Prospectus or any “issuer information” filed or required to be filed pursuant to Rule 433(d), or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; and will reimburse each Underwriter and each such controlling person for any legal or other expenses reasonably incurred by such Underwriter or such controlling person in connection with investigating or defending any such loss, claim, damage, liability or action; provided, however, that neither Issuer nor Japan will be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any of such documents in reliance upon and in conformity with written information furnished to either Issuer or Japan by any Underwriter through the Representative[s] specifically for use therein. This indemnity agreement will be in addition to any liability which Issuer or Japan may otherwise have.

(b) Each Underwriter severally will indemnify and hold harmless Issuer, each of its officers who have signed the Registration Statement and Japan against any losses, claims, damages or liabilities to which Issuer, any such officer or Japan may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement, the Base Prospectus, any Preliminary Final Prospectus, the Final Prospectus, or any amendment or supplement thereto relevant to the Securities, or arise out of or are based upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in reliance upon and in conformity with written information furnished to Issuer or Japan by such Underwriter through the Representative[s] specifically for use therein pursuant to Section 2(b) hereof; and will reimburse Issuer or Japan for any legal or other expenses reasonably incurred by Issuer, any such officer or Japan in connection with investigating or defending any such loss, claim, damage, liability or action. This indemnity agreement will be in addition to any liability which such Underwriter may otherwise have.

(c) Promptly after receipt by an indemnified party under this Section of notice of the commencement of any action, such indemnified party will, if a claim in respect thereof is to be made against the indemnifying party under this Section, notify the indemnifying party of the commencement thereof; but the omission so to notify the indemnifying party will not relieve it from any liability which it may have to any indemnified party otherwise than under this Section. In case any such action is brought against any indemnified party, and it notifies the indemnifying party of the commencement thereof, the indemnifying party will be entitled to participate therein and, to the extent that it may wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party will not be liable to such indemnified party under this Section for any legal or other expenses subsequently incurred by the indemnified party in connection with the defense thereof other than reasonable costs of investigation. The indemnifying party shall not be liable for any settlement of any such action effected without its consent, but if settlement is made with the consent of the indemnifying party, such indemnifying party shall indemnify and hold harmless the indemnified party against any loss or liability by reason of such settlement. In any such action brought against Japan, the defense of which shall be assumed by any Underwriter or Underwriters, Japan may, at its option, elect by notice to such Underwriter or Underwriters to direct that any defense based on sovereign immunity, which would otherwise be available to it, shall not be asserted in such action, and each Underwriter agrees, upon receipt of any such notice, not to assert such defense. Such an election not to have such defense asserted shall not release any Underwriter from the indemnity agreement on the part of such Underwriter contained in this Section.

(d) If recovery is not available under the foregoing indemnification provisions of this Section, for any reason other than as specified therein, the parties entitled to indemnification by the terms thereof shall be

entitled to contribution to liabilities and expenses, except to the extent that contribution is not permitted under Section 11(f) of the Act. In determining the amount of contribution to which the respective parties are entitled, there shall be considered the relative benefits received by each party from the offering of the Securities (taking into account the portion of the proceeds of the offering realized by each), the parties’ relative knowledge and access to information concerning the matter with respect to which the claim was asserted, the opportunity to correct and prevent any statement or omission, and any other equitable considerations appropriate under the circumstances. Issuer and Japan, on the one hand, and the Underwriters, on the other hand, agree that it would not be equitable if the amount of such contribution were determined by pro rata or per capita allocation (even if the Underwriters were treated as one entity for such purpose). No Underwriter or person controlling such Underwriter shall be obligated to make contribution hereunder which in the aggregate exceeds the total public offering price of the Securities purchased by such Underwriter under this Agreement, less the aggregate amount of any damages which such Underwriter and its controlling persons have otherwise been required to pay in respect of the same claim or any substantially similar claim. The Underwriters’ obligations to contribute are several in proportion to their respective underwriting obligations and not joint.

9. Default of Underwriters. If any Underwriter or Underwriters default in their obligations to purchase Securities hereunder and the aggregate principal amount of Securities which such defaulting Underwriter or Underwriters agreed but failed to purchase does not exceed 10% of the total principal amount of the Securities as set forth in Schedule II hereto, the Representative[s] may make arrangements satisfactory to Issuer and Japan for the purchase of such Securities by other persons, including any of the Underwriters, but if no such arrangements are made by the Closing Date the non-defaulting Underwriters shall be obligated severally, in proportion to their respective commitments hereunder as set forth in Schedule II hereto, to purchase the Securities which such defaulting Underwriter or Underwriters agreed but failed to purchase. If any Underwriter or Underwriters so default and the aggregate principal amount of the Securities with respect to which such default or defaults occur is more than 10% of the total principal amount of Securities as set forth in Schedule II hereto, and arrangements satisfactory to the Representative[s] and to Issuer and Japan for the purchase of such Securities by other persons shall not be made within thirty-six hours after such default, this Agreement will terminate without liability on the part of any non-defaulting Underwriter or Issuer or Japan, except for the expenses to be paid by Issuer pursuant to Section 5(b)(i) hereof and the continuation of the respective obligations of Issuer, Japan and the Underwriters pursuant to Section 8 hereof. As used in this Agreement, the term “Underwriter” includes any person substituted for a defaulting Underwriter under this Section. Nothing herein will relieve a defaulting Underwriter from liability for its default.

10. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of Issuer, its officers and Japan and of the several Underwriters set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation, or statement as to the results thereof, made by or on behalf of any Underwriter or Issuer, its officers or Japan or any controlling person of any Underwriter, and will survive delivery of and payment for the Securities.

11. Notices. All communications hereunder will be in writing and, if sent to the Underwriters, will be mailed, delivered, telexed, or telegraphed and confirmed to the Representative[s] at the address specified in Schedule I hereto; or, if sent to Issuer or Japan, will be addressed to the Authorized Agent in the United States for Issuer, as specified in Schedule I hereto and to the Authorized Agent in the United States for Japan, as specified in Schedule I hereto; provided, however, that any notice to an Underwriter pursuant to Section 8 will be mailed, delivered, telexed, or telegraphed to such Underwriter at its address appearing in the list of Underwriters’ names and addresses furnished to Issuer and Japan for the purpose of communications hereunder.

12. Successors. This Agreement will inure to the benefit of and be binding upon the parties hereto and their respective successors and the controlling persons and officers referred to in Section 8 hereof, and no other person will have any right or obligation hereunder.

13. Representation of Underwriters. The Representative[s] will act for the several Underwriters in connection with the offering of the Securities for sale to the public as set forth in the Final Prospectus, and any action under this Agreement taken by the Representative[s] jointly or by the firm first listed in Schedule I hereto as being one of the Representative[s] will be binding upon all the Underwriters.

14. Governing Law. This Agreement shall be governed by, and interpreted in accordance with, the laws of the State of New York except with respect to its authorization and execution by Issuer and Japan and any other matters required to be governed by the laws of Japan.

15. Jurisdiction of Courts of New York and Japan. Issuer hereby appoints the U.S. Representative, as its authorized agent (the “Process Agent”) upon which process may be served in any action by any Underwriter, or by any person controlling such Underwriter, arising out of or based upon this Agreement which may be instituted in any State or Federal court in The City of New York, and Issuer expressly accepts the jurisdiction of any such court in respect of any such action. Such appointment shall be irrevocable as long as any of the Securities remain outstanding unless and until the appointment of a successor Fiscal Agent as Issuer’s Process Agent and such successor’s acceptance of such appointment shall have occurred. Issuer will take any and all action, including the filing of any and all documents and instruments, that may be necessary to continue such appointment or appointments in full force and effect as aforesaid. Service of process upon the Process Agent and written notice of such service mailed or delivered to Issuer, in Tokyo, Japan shall be deemed in every respect effective service of process upon Issuer. Notwithstanding the foregoing, any action by an Underwriter arising out of or based upon this Agreement may be instituted by any Underwriter in any competent court in Japan. Issuer hereby waives irrevocably any immunity to which it might otherwise be entitled in any action arising out of or based upon this Agreement which may be instituted as provided in this Section in any State or Federal court in The City of New York or in any competent court in Japan. This waiver is intended to be effective upon execution of this Agreement without any further act by Issuer before any such court and introduction of a true copy of this Agreement into evidence shall be conclusive and final evidence of such waiver.

If the foregoing is in accordance with your understanding of our agreement, kindly sign and return to us the enclosed duplicate hereof, whereupon it will become a binding agreement among Issuer, Japan and the several Underwriters in accordance with its terms.
