March 26, 2018

To the Several Underwriters

Named in Schedule A

Ladies and Gentlemen:

Introductory. ABB Finance (USA) Inc., a Delaware corporation (the “Company”), proposes to issue and sell to the several underwriters named in Schedule A (the “Underwriters”), acting severally and not jointly, the respective principal amounts set forth in such Schedule A of $300,000,000 aggregate principal amount of the Company’s 2.800% Notes due 2020 (the “2020 Notes”), $450,000,000 aggregate principal amount of the Company’s 3.375% Notes due 2023 (the “2023 Notes”) and $750,000,000 aggregate principal amount of the Company’s 3.800% Notes due 2028 (the “2028 Notes” and, together with the 2020 Notes and the 2023 Notes, the “Notes”). Citigroup Global Markets Inc. (“Citigroup”), Credit Suisse Securities (USA) LLC (“Credit Suisse”) and J.P. Morgan Securities LLC (“J.P. Morgan”) have agreed to act as representatives of the several Underwriters (in such capacity, the “Representatives”) in connection with the offering and sale of the Notes.

The Notes will be issued as a series of debt securities pursuant to an indenture, to be dated April 3, 2018 (the “Base Indenture”), by and among the Company, ABB Ltd, an entity organized under the laws of Switzerland and indirect parent of the Company, as guarantor (the “Guarantor”), and Deutsche Bank Trust Company Americas, as trustee (the “Trustee”). Certain terms of the Notes will be established under a supplemental indenture (the “Supplemental Indenture”), to the Base Indenture (together with the Base Indenture, the “Indenture”). The Notes will be issued in book-entry form in the name of Cede & Co., as nominee of The Depository Trust Company (the “Depositary”), pursuant to a Blanket Issuer Letter of Representations, to be dated on or before the Closing Date (as defined in Section 2) (the “DTC Agreement”), between the Company and the Depositary.

The payment obligations of the Company under the Notes will be fully and unconditionally guaranteed by the Guarantor pursuant to an instrument of guarantee (the “Guarantee” and, together with the Notes, the “Securities”) to be issued pursuant to the Indenture.

The Company and the Guarantor have prepared and filed with the Securities and Exchange Commission (the “Commission”) an automatic shelf registration statement on Form F-3 (File No. 333-223907), which contains a base prospectus (the “Base Prospectus”), to be used in connection with the public offering and sale of debt securities of the Company, including the Notes, and guarantees of the Guarantor, including the Guarantee, under the Securities Act of 1933, as amended, and the rules and regulations promulgated thereunder (collectively, the “Securities Act”), and the offering thereof from time to time in accordance with Rule 415 under the Securities Act, which automatic shelf registration statement became effective under Rule 462(e) under the Securities Act (“Rule 462(e)”) upon filing. The term “Registration Statement,” as of any time, shall mean such registration statement as amended by any post-effective amendment thereto at such time, including the financial statements, exhibits and schedules thereto at such time and the documents deemed (pursuant to Rule 430B under the Securities Act (“Rule 430B”)) to be a part thereof as of such time; provided, however, that the term “Registration Statement” without reference to a time means such registration statement as amended by any post-effective amendment thereto as of the time of the first contract of sale for the Securities, which time shall be considered the “new effective date” of the Registration Statement with respect to the Securities within the meaning of Rule 430B(f)(2), including the financial statements, exhibits and schedules thereto as of such time and documents deemed (pursuant to Rule 430B) to be a part thereof as of such time. The term “Prospectus” shall mean the final prospectus supplement relating to the Securities, together with the Base Prospectus, that is first filed pursuant to Rule 424(b) under the Securities Act (“Rule 424(b)”) after the date and time that this Agreement is executed (the “Execution Time”) by the parties hereto. The term “Preliminary Prospectus” shall mean any preliminary prospectus supplement relating to the Securities, together with the Base Prospectus, that is filed with the Commission pursuant to Rule 424(b), including the “Pricing Preliminary Prospectus,” which shall mean the preliminary prospectus supplement, dated March 26, 2018, relating to the Securities, together with the Base Prospectus, that is filed with the Commission pursuant to Rule 424(b). All references in this Agreement to the Registration Statement, any Preliminary Prospectus or the Prospectus shall be deemed to include the documents that are or are deemed to be incorporated by reference therein pursuant to Item 6 of Form F-3 under the Securities Act prior to the Execution Time. All references in this Agreement to the

Registration Statement, any Preliminary Prospectus or the Prospectus, or any amendments or supplements to any of the foregoing, shall include any copy thereof filed with the Commission pursuant to its Electronic Data Gathering, Analysis and Retrieval System (“EDGAR”).

All references in this Agreement to financial statements, exhibits and schedules thereto and other information which is “contained,” “disclosed,” “described,” “included” or “stated” (or other references of like import) in the Registration Statement, the Disclosure Package (as defined in Section 1(b)), or any component thereof, or the Prospectus shall be deemed to include all such financial statements, exhibits and schedules thereto and other information which are or are deemed to be incorporated by reference in the Registration Statement, the Disclosure Package, or any component thereof, or the Prospectus, as the case may be, prior to the Execution Time; and all references in this Agreement to amendments or supplements to the Registration Statement, the Disclosure Package, or any component thereof, or the Prospectus shall be deemed to include the filing of any document under the Securities Exchange Act of 1934, as amended, and the rules and regulations promulgated thereunder (collectively, the “Exchange Act”), which is or is deemed to be incorporated by reference in the Registration Statement, the Disclosure Package, or any component thereof, or the Prospectus, as the case may be, at or after the Execution Time.

Each of the Company and the Guarantor hereby confirms its agreements with the Underwriters as follows:

SECTION 1. Representations and Warranties of the Company and the Guarantor

The Company and the Guarantor, jointly and severally, hereby represent, warrant and covenant to each Underwriter at the Execution Time, the Initial Sale Time (as defined below) and the Closing Date (in each case, a “Representation Date”), as follows:

a) Compliance with Registration Requirements. Each of the Company and the Guarantor meets the requirements for use of Form F-3 under the Securities Act. The Registration Statement is an “automatic shelf registration statement,” as defined in Rule 405 under the Securities Act (“Rule 405”), and offers and sales of the Securities have been, and remain eligible for, registration by the Company or the Guarantor, as applicable, on such automatic shelf registration statement. Each of the Registration Statement and any post-effective amendment thereto has become effective under Rule 462(e) under the Securities Act upon filing. No stop order suspending the effectiveness of the Registration Statement or any post-effective amendment thereto has been issued under the Securities Act, no notice of objection of the Commission to the use of the Registration Statement or any post-effective amendment thereto pursuant to Rule 401(g)(2) under the Securities Act (“Rule 401(g)(2)”) has been received by the Company or the Guarantor, no order preventing or suspending the use of any Preliminary Prospectus, any Issuer Free Writing Prospectus (as defined in Section 1(b)) or the Prospectus or any amendment or supplement thereto has been issued and no proceedings for any of those purposes have been instituted or are pending, or, to the Guarantor’s knowledge, contemplated. The Company and the Guarantor have complied with each request (if any) from the Commission for additional information. In addition, the Indenture has been duly qualified under the Trust Indenture Act of 1939, as amended, and the rules and regulations promulgated thereunder (the “Trust Indenture Act”).

At the respective times the Registration Statement and any post-effective amendments thereto became effective and at each Representation Date, the Registration Statement and each amendment thereto, if any, (i) complied, complies and will comply in all material respects with the requirements of the Securities Act and the Trust Indenture Act, and (ii) did not, do not and will not contain an untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading. At the date of the Prospectus, at the date of any amended Prospectus and at the Closing Date, the Prospectus and each amendment or supplement thereto (i) complied, complies and will comply in all material respects with the requirements of the Securities Act and the Trust Indenture Act and (ii) did not and will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. Notwithstanding the foregoing, the representations and warranties in this subsection shall not apply to statements in or omissions from the Registration Statement or any amendment thereto or the Prospectus or any amendment or supplement thereto made in reliance upon and in conformity with information furnished to the Company and the Guarantor in writing by any of the Underwriters through the Representatives expressly for use therein, it being understood and agreed that the only

such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 8(b).

Each Preliminary Prospectus and the Prospectus delivered to the Underwriters for use in connection with the offering of the Securities, at the time of such delivery, was or will be identical to any electronically transmitted copies thereof filed with the Commission pursuant to EDGAR, except to the extent permitted by Regulation S-T.

b) Disclosure Package. The term “Disclosure Package” shall mean (i) the Pricing Preliminary Prospectus, (ii) each issuer free writing prospectus, as defined in Rule 433 under the Securities Act (“Rule 433”) (each, an “Issuer Free Writing Prospectus”), if any, identified in Annex I hereto and (iii) any other free writing prospectus that the parties hereto shall hereafter expressly agree in writing to treat as part of the Disclosure Package. At 5:20 p.m., New York City time on March 26, 2018 (the “Initial Sale Time”), the Disclosure Package did not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Disclosure Package made in reliance upon and in conformity with information furnished to the Company and the Guarantor in writing by any of the Underwriters through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 8(b).

c) Incorporated Documents. The documents incorporated or deemed to be incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus (i) at the time they were or hereafter are filed with the Commission, complied or will comply in all material respects with the requirements of the Exchange Act and (ii) when read together with the other information in the Disclosure Package, at the Initial Sale Time, and when read together with the other information in the Prospectus, at the date of the Prospectus and at the Closing Date, did not, do not and will not include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

d) The Guarantor is a Well-Known Seasoned Issuer. (i) At the time of filing the Registration Statement, (ii) at the time of the most recent amendment thereto for the purposes of complying with Section 10(a)(3) of the Securities Act (whether such amendment was by post-effective amendment, incorporated report filed pursuant to Section 13 or 15(d) of the Exchange Act or form of prospectus), (iii) at the time the Company, the Guarantor or any person acting on their behalf (within the meaning, for this clause only, of clause (c) of Rule 163 under the Securities Act (“Rule 163”)) made any offer relating to the Securities in reliance on the exemption of Rule 163, (iv) at the Execution Time and (v) at the Initial Sale Time, the Guarantor was and is a “well known seasoned issuer,” as defined in Rule 405.

e) Not an Ineligible Issuer. (i) At the time of filing the Registration Statement and (ii) at the Execution Time (with such date being used as the determination date for purposes of this clause (ii)), each of the Company and the Guarantor was not and is not an “ineligible issuer,” as defined in Rule 405, without taking account of any determination by the Commission pursuant to Rule 405 that it is not necessary that the Company or the Guarantor, as the case may be, be considered an ineligible issuer.

f) Issuer Free Writing Prospectuses. Each Issuer Free Writing Prospectus, as of its issue date and at all subsequent times through the completion of the offering of the Securities under this Agreement or until any earlier date that the Company or the Guarantor notified or notifies the Underwriters as described in the next sentence, did not, does not and will not include any information that conflicted, conflicts or will conflict with the information contained in the Registration Statement, any Preliminary Prospectus or the Prospectus. If at any time following issuance of an Issuer Free Writing Prospectus and prior to the later of the Closing Date and the expiration of the Prospectus Delivery Period (as defined in Section 3(b)) any event shall occur as a result of which such Issuer Free Writing Prospectus conflicted, conflicts or would conflict with the information contained in the Registration Statement, any Preliminary Prospectus or the Prospectus, the Company or the Guarantor has promptly notified or will promptly notify the Underwriters and has promptly amended or supplemented or will promptly amend or supplement, at its own expense, such Issuer Free Writing Prospectus to eliminate or correct such conflict. The foregoing two sentences do not apply to statements in or omissions from any Issuer Free Writing Prospectus made in

reliance upon and in conformity with information furnished to the Company and the Guarantor in writing by any of the Underwriters through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 8(b). Any offer that is a written communication relating to the Securities made prior to the initial filing of the Registration Statement by the Company, the Guarantor or any person acting on their behalf (within the meaning, for this paragraph only, of Rule 163(c)) has been filed with the Commission in accordance with the exemption provided by Rule 163 and otherwise complied with the requirements of Rule 163, including, without limitation, the legending requirement, to qualify for the exemption from Section 5(c) of the Securities Act provided by Rule 163.

g) Distribution of Offering Material By the Company and the Guarantor. Neither the Company nor the Guarantor has distributed or referred to, or will distribute or refer to, prior to the later of the Closing Date and the expiration of the Prospectus Delivery Period, any written communication (as defined in Rule 405) concerning the offer or sale of the Securities other than the Registration Statement, the Disclosure Package (including the components thereof), the Prospectus and any electronic road show or other written communication reviewed and consented to by the Representatives and identified in Annex II hereto (each such electronic road show or other written communication, an “Additional Written Communication”). Each Additional Written Communication, when read together with the Disclosure Package, at the Initial Sale Time, did not, and at the Closing Date, will not, include an untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading. The preceding sentence does not apply to statements in or omissions from the Additional Written Communication made in reliance upon and in conformity with information furnished to the Company and the Guarantor in writing by any of the Underwriters through the Representatives expressly for use therein, it being understood and agreed that the only information furnished by any Underwriter through the Representatives consists of the information described as such in Section 8(b). The statistical and market-related data included in the Registration Statement, the Disclosure Package and the Prospectus are based on or derived from sources that each of the Company and the Guarantor believes to be reliable and accurate.

h) Capitalization and Other Capital Stock Matters. At the Closing Date, the capitalization set forth in the Registration Statement, the Pricing Preliminary Prospectus and the Prospectus under the heading “Capitalization” in the “Historical” column is true and correct in all material respects. There are no holders of securities of the Company or the Guarantor that are entitled to have such securities registered for resale under the Registration Statement or otherwise registered for resale under the Securities Act.

i) Incorporation and Good Standing. Each of the Company, the Guarantor and the Material Subsidiaries (as defined below) (i) has been duly incorporated and is validly existing (and, if applicable, in good standing) under the laws of its jurisdiction of incorporation, is not in liquidation or receivership and has all requisite corporate power and authority to own its properties and conduct its business as now conducted and as described in the Registration Statement, the Disclosure Package and the Prospectus and (ii) is duly qualified to do business as a foreign corporation and, if applicable, is in good standing in all other jurisdictions where the ownership or leasing of its properties and assets or the conduct of its business requires such qualification, except where the failure to be so qualified would not, individually or in the aggregate, reasonably be expected to have a material adverse effect on the general affairs, management, business, condition (financial or otherwise), prospects or results of operations of the Guarantor and its subsidiaries (including the Company), considered together as one entity, whether or not arising from transactions in the ordinary course of business (any such event, a “Material Adverse Effect”). The Guarantor owns, directly or indirectly, all of the issued and outstanding shares of capital stock of the Company and the Material Subsidiaries free and clear of all liens, encumbrances, equities and claims. “Material Subsidiary” means a company the financial statements of which are consolidated with those of the Guarantor that: (i) is the holding company of a country (and not a region) that, together with its subsidiaries, has combined third-party revenues in excess of 5% of the consolidated revenues of the Guarantor and its subsidiaries (collectively, the “ABB Group”) for the most recently completed fiscal year; (ii) on a non-consolidated legal entity basis, has third-party revenues in excess of 10% of the consolidated revenues of the ABB Group for the most recently completed fiscal year; or (iii) has any notes, bonds, debenture stock, loan stock or other securities outstanding to non-ABB Group third parties in respect of which a guarantee, keep-well agreement or other credit support has been provided by the Guarantor; provided that (i) third-party revenues shall exclude any revenues not included in total revenues in the consolidated income statement of the ABB Group, (ii) the term “revenues” shall exclude any revenues attributable to activities

classified by the Guarantor as discontinued operations in the consolidated financial statements of the ABB Group, and (iii) all revenue figures shall be prepared in accordance with GAAP (as defined herein) as used in the preparation of the consolidated financial statements of the ABB Group. As of December 31, 2017, the entities listed in Schedule B hereto are the only Material Subsidiaries.

j) Due Authorization and Enforceability of this Agreement, the Notes, the Guarantee and the Indenture. The Company has all requisite corporate power and authority to execute, deliver and perform each of its obligations under this Agreement, the Notes and the Indenture. The Guarantor has all requisite corporate power and authority to perform its obligations under this Agreement, the Guarantee and the Indenture. This Agreement and the consummation by each of the Company and the Guarantor (as applicable) of the transactions contemplated hereby have been duly and validly authorized, and this Agreement has been duly executed and delivered, by each of the Company and the Guarantor. The Notes, when issued, will be in the form contemplated by the Indenture and will have each been duly and validly authorized and executed by the Company and, when authenticated by the Trustee in accordance with the provisions of the Indenture and delivered to, and paid for, by the Underwriters in accordance with the terms of this Agreement, will constitute valid and legally binding obligations of the Company, enforceable against the Company in accordance with their terms, except that the enforcement thereof may be subject to (i) bankruptcy, insolvency, reorganization, fraudulent conveyance or moratorium or other similar laws now or hereafter in effect relating to creditors’ rights generally, and (ii) general principles of equity and the discretion of the court before which any proceeding therefor may be brought (collectively, the “Enforceability Exceptions”), and will be entitled to the benefits of the Indenture and the Guarantee. The Indenture has been duly and validly authorized by each of the Company and the Guarantor and, at the Closing Date, will have been duly and validly executed and delivered by each of the Company and the Guarantor and (assuming the due authorization, execution and delivery by the Trustee) will constitute a valid and legally binding agreement of each of the Company and the Guarantor, enforceable against each of the Company and the Guarantor in accordance with its terms, except that the enforcement thereof may be subject to the Enforceability Exceptions. The Guarantee, when executed, will be in the form contemplated by the Indenture and, at the Closing Date, will have been duly and validly authorized, executed and delivered by the Guarantor and, when the Notes have been duly executed, authenticated, issued and delivered in the manner provided for in the Indenture and paid for by the Underwriters in accordance with the terms of this Agreement, will constitute a valid and legally binding agreement of the Guarantor, enforceable against the Guarantor in accordance with its terms, except that the enforcement thereof may be subject to the Enforceability Exceptions.

k) Accuracy of Descriptions of Notes, Guarantee and Indenture. The Notes, the Guarantee and the Indenture will conform in all material respects to the descriptions thereof in the Registration Statement, the Disclosure Package and the Prospectus.

l) Absence of Conflicts or Defaults; No Further Authorizations or Approvals Required. None of the Guarantor, the Company or any of the Material Subsidiaries is (i) in violation of its certificate of incorporation or bylaws (or similar organizational document), (ii) in breach or violation of any statute, judgment, decree, order, rule or regulation applicable to the Guarantor or any of its subsidiaries (including the Company) or any of their respective properties or assets, except for any such breach or violation that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or prevent the consummation of the transactions contemplated under, or performance of, this Agreement, the Indenture, the Notes or the Guarantee, or (iii) in breach of, or default under (nor has any event occurred that, with notice or passage of time or both, would constitute a default under), or in violation of, any of the terms or provisions of any indenture, mortgage, deed of trust, loan agreement, note, lease, license, franchise agreement, permit, certificate, contract or other agreement or instrument to which the Guarantor or any of its subsidiaries (including the Company) is a party or by which the Guarantor or any of its subsidiaries (including the Company) may be bound or to which any of the properties or assets of the Guarantor or any of its subsidiaries (including the Company) is subject (collectively, the “Contracts”), except for any such breach, default, violation or event that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or prevent the consummation of the transactions contemplated under, or performance of, this Agreement, the Indenture, the Notes or the Guarantee. The execution, delivery and performance by the Company and the Guarantor, as applicable, of this Agreement, the Indenture, the Notes and the Guarantee, and the consummation by the Company and the Guarantor of the transactions contemplated hereby and thereby (including, without limitation, the issuance and sale of the Securities to the Underwriters) do not and will not conflict with, or constitute or result in a breach of or a default under (or an event that with notice or passage of

time or both would constitute a default under), or violation of, or result in the creation or imposition of any lien, charge or encumbrance upon any properties or assets of the Guarantor or any of its subsidiaries (including the Company) pursuant to, or permit or require the acceleration of any indebtedness under, any of (i) the terms or provisions of any Contract, except, in the case of this clause (i), for any such conflict, breach, violation, default, event or acceleration that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or prevent the consummation of the transactions contemplated under, or performance of, this Agreement, the Indenture, the Notes or the Guarantee, (ii) the certificate of incorporation or bylaws (or similar organizational document) of the Company, the Guarantor or any of Material Subsidiaries or (iii) (assuming compliance with all applicable state and non-U.S. securities laws) any statute, judgment, decree, order, rule or regulation applicable to the Guarantor or any of its subsidiaries (including the Company) or any of their respective properties or assets, except, in the case of this clause (iii), for any such conflict, breach, violation, default, event or acceleration that would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or prevent the consummation of the transactions contemplated under, or performance of, this Agreement, the Indenture, the Notes or the Guarantee. No consent, approval, authorization or order of, or registration or filing with, any court or governmental agency or body or third party is required for execution, delivery and performance of this Agreement, the Indenture or the Guarantee, or the issuance and sale by the Company of the Notes to the Underwriters or the consummation by the Company and the Guarantor of the other transactions contemplated hereby, except such as have been obtained or made, and are in full force and effect, under the Securities Act and the Trust Indenture Act and such as may be required under the securities laws of any state or non-U.S. jurisdiction or by the Financial Industry Regulatory Authority, Inc. (“FINRA”) in connection with the offering and sale of the Securities (including the purchase and resale of the Securities by the Underwriters).

m) Financial Statements. The consolidated financial statements of the Guarantor incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus present fairly in all material respects the financial position, results of operations and cash flows of the Guarantor at the dates and for the periods to which they relate and have been prepared in accordance with, and are in conformity with, U.S. generally accepted accounting principles (“GAAP”) applied on a consistent basis, except as otherwise stated therein. No other historical or pro forma financial statements or supporting schedules are required to be included or incorporated by reference in the Registration Statement, the Disclosure Package or the Prospectus under the Securities Act or the Exchange Act. All disclosures contained in the Registration Statement, the Disclosure Package or the Prospectus regarding “non-GAAP financial measures” (as such term is defined by the rules and regulations of the Commission) comply with Regulation G under the Exchange Act and Item 10 of Regulation S-K under the Securities Act, to the extent applicable. The interactive data in eXtensible Business Reporting Language incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus fairly presents the information called for in all material respects and has been prepared in accordance with the Commission’s rules and guidelines applicable thereto. Ernst & Young AG is an independent public accounting firm (within the meaning of the Securities Act and Exchange Act) with respect to the Guarantor and the Company and is an independent registered public accounting firm with the Public Company Accounting Oversight Board.

n) Legal Proceedings; All Required Descriptions and Exhibits; Accuracy of Contract Descriptions. There is not pending or, to the knowledge of the Guarantor, threatened any action, suit, proceeding, inquiry or investigation to which the Guarantor or any of its subsidiaries (including the Company) is a party, or to which any of the properties or assets of the Guarantor or any of its subsidiaries (including the Company) are subject, before or brought by any court, arbitrator or governmental agency, authority or body that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or that seeks to restrain, enjoin, prevent the consummation of or otherwise challenge the issuance or sale of the Securities hereunder or the consummation of the other related transactions described in the Registration Statement, the Disclosure Package and the Prospectus. There are no legal or governmental proceedings involving or affecting the Guarantor, any of its subsidiaries (including the Company), any directors or officers of the Guarantor or any of its subsidiaries (including the Company) or any of the properties or assets of the Guarantor or any of its subsidiaries (including the Company) required to be described in the Registration Statement, the Disclosure Package or the Prospectus that are not described in the Registration Statement, the Disclosure Package and the Prospectus, nor are there any material contracts or other documents that are required to be described in the Registration Statement, the Disclosure Package and the Prospectus or to be filed as exhibits to the Registration Statement which have not been so described and filed as required. All descriptions in the Registration Statement, the Disclosure Package and the Prospectus of contracts and other documents to which the Guarantor or any of its subsidiaries (including the Company) is a party are accurate in all material respects.

o) All Necessary Licenses, Permits, etc. The Guarantor and its subsidiaries (including the Company) possess all licenses, permits, certificates, consents, orders, approvals and other authorizations from, and have made all declarations and filings with, all local, state, U.S. federal, foreign and other governmental authorities, all self-regulatory organizations and all courts and other tribunals, presently required or necessary to own or lease, as the case may be, and to operate their respective properties and assets and to carry on their respective businesses as now or proposed to be conducted as set forth in the Registration Statement, the Disclosure Package and the Prospectus (collectively, the “Permits”), except where the failure to possess such Permits or make such declarations or filings could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Guarantor and its subsidiaries (including the Company) have fulfilled and performed all of their respective obligations with respect to such Permits and no event has occurred that allows, or after notice or lapse of time would allow, revocation or termination thereof or results in any other impairment of the rights of the Guarantor or any such subsidiary in respect of any such Permit that would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. Neither the Guarantor nor any of its subsidiaries (including the Company) has received any notice of any proceeding relating to revocation or modification of any such Permit, except where such revocation or modification would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

p) No Material Adverse Effect and Other Matters. Since the date of the most recent financial statements incorporated by reference in the Registration Statement, the Disclosure Package and the Prospectus, except as described in the Registration Statement, the Disclosure Package and the Prospectus, (i) neither the Guarantor nor any of its subsidiaries (including the Company) have incurred any liabilities or obligations, direct or contingent, or have entered into or agreed to enter into any transactions or contracts (written or oral), in each case other than in the ordinary course of business, which liabilities, obligations, transactions or contracts would, individually or in the aggregate, be material to the general affairs, management, business, condition (financial or otherwise), prospects or results of operations of the Guarantor and its subsidiaries (including the Company), considered together as one entity, and (ii) there shall not have been any Material Adverse Effect.

q) Tax Law Compliance. The Guarantor and its subsidiaries (including the Company) have filed all necessary U.S. local, state and federal and non-U.S. income and franchise tax returns required to be filed as of the date hereof or obtained extensions of time in respect of such filings, except where the failure to so file such returns could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, and have paid all taxes shown as due thereon. Other than tax deficiencies that the Guarantor or any of its subsidiaries (including the Company) are contesting in good faith and for which the Guarantor has provided adequate reserves, there is no tax deficiency that has been asserted against the Guarantor or any of its subsidiaries (including the Company) that could, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect.

r) Title to Properties; Valid Contracts; Intellectual Property Rights. The Guarantor and its subsidiaries (including the Company) have good and marketable title to all real property and good title to all personal property described in the Registration Statement, the Disclosure Package and the Prospectus as being owned by them and good and marketable title to a leasehold estate in the real and personal property described in the Registration Statement, the Disclosure Package and the Prospectus as being leased by them, in each case free and clear of all liens, charges, encumbrances or restrictions, except to the extent the failure to have such title or the existence of such liens, charges, encumbrances or restrictions would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. All Contracts to which the Guarantor or any of its subsidiaries (including the Company) are a party or by which the Guarantor or any of its subsidiaries (including the Company) are bound are valid and enforceable against the Guarantor or any such subsidiary, as the case may be, and, to the Guarantor’s knowledge, against the other party or parties thereto and are in full force and effect with only such exceptions as could not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect. The Guarantor and its subsidiaries (including the Company) own or possess adequate licenses or other rights to use all patents, trademarks, service marks, trade names, copyrights and know-how necessary to conduct the businesses now or proposed to be operated by them as described in the Registration Statement, the Disclosure Package and the Prospectus with only such exceptions as would not, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect, and neither the Guarantor nor any of its subsidiaries (including the Company) have received any notice of infringement of or conflict with (or know of any such infringement of or conflict with) asserted rights of others with respect to any patents, trademarks, service marks, trade names, copyrights or know-

l) Permitted Free Writing Prospectuses. Each of the Company and the Guarantor represents that it has not made, and agrees that, unless it obtains the prior written consent of the Representatives, it will not make, any offer relating to the Securities that would constitute an Issuer Free Writing Prospectus or that would otherwise constitute a “free writing prospectus” (as defined in Rule 405) required to be filed by the Company or the Guarantor

References herein to the Registration Statement shall include such new registration statement or post-effective amendment, as the case may be.

o) Rule 158. The Guarantor will make generally available to its security holders, as soon as it is practicable to do so, but in any event not later than 15 months after the effective date of the Registration Statement (as defined in Rule 158(c) under the Securities Act), an earnings statement (which need not be audited) in reasonable detail, complying with the requirements of Section 11(a) of the Securities Act and Rule 158 thereunder and will advise the Representatives in writing when such statement has been so made available.

In that event, the Company or the Guarantor, as the case may be, will pay such additional amounts as may be necessary in order the net amounts received after such withholding or deduction shall equal the amounts that would have been received if no withholding or deduction had been made; except to the extent that such taxes, duties, or governmental charges were withheld or deducted due to (A) an Underwriter having any present or former connection with such jurisdiction other than solely as a result of the execution and delivery of, or performance of, its obligations under this Agreement or receipt of any payments or enforcement of rights hereunder or (B) the failure of an Underwriter to use its reasonable efforts to provide any other form, certificate, document or other information that would have reduced or eliminated the withholding or deduction of such taxes, duties, or governmental charges..

SECTION 5. Conditions of the Obligations of the Underwriters. The obligations of the several Underwriters to purchase and pay for the Notes as provided herein on the Closing Date shall be subject to the accuracy of the representations and warranties set forth in Section 1 (including any representation and warranty set forth in any certificate of the officer of the Company or the Guarantor) on the part of each of the Company and the Guarantor on each Representation Date and to the timely performance by each of the Company and the Guarantor of its covenants and other obligations hereunder, and to each of the following additional conditions:

On the date hereof, the Representatives shall have received from Ernst & Young AG, independent registered public accountants for the ABB Group, a letter dated the date hereof addressed to the Underwriters and the Board of Directors of the Guarantor, in form and substance reasonably satisfactory to the Representatives, with respect to the audited and unaudited financial statements and certain financial information contained in the Registration Statement, the Disclosure Package and the Prospectus and any amendments or supplements thereto.

(ii) there shall not have been any change or decrease specified in the letter or letters referred to in paragraphs (b) or (c) of this Section 5 which is, in the sole judgment of the Representatives, so material and

adverse as to make it impractical or inadvisable to proceed with the offering or delivery of the Securities as contemplated by the Registration Statement, the Disclosure Package and the Prospectus; and

(iii) there shall not have occurred any downgrading in, or withdrawal of, and there shall not have been given any notice of any intended or potential downgrading in, or withdrawal of, or change in outlook (other than one with positive implications in outlook) or of any review for a possible change that does not indicate a stable or positive direction of the possible change in, the rating accorded to any securities of the Guarantor or any of the Guarantor’s subsidiaries (including the Company) by any “nationally recognized statistical rating organization,” as such term is defined in Section 3(a)(62) of the Exchange Act.

(i) at the Execution Time and at the Closing Date, subsequent to the date of the most recent financial statements in the Registration Statement, the Disclosure Package and the Prospectus, no event or development has occurred, and no information has become known, that individually or in the aggregate, has or would be reasonably likely to have a Material Adverse Effect;

If any condition specified in this Section 5 is not satisfied when and as required to be satisfied, this Agreement may be terminated by the Representatives by written notice to the Company and the Guarantor at any time on or prior to the Closing Date, which termination shall be without liability on the part of any party to any other party, except that Sections 4, 6, 8 and 16 shall at all times be effective and shall survive such termination.

SECTION 6. Reimbursement of Underwriters’ Expenses. If this Agreement is terminated by the Representatives pursuant to Section 5, 9 or 10, or if the sale to the Underwriters of the Securities on the Closing

Date is not consummated because of any refusal, inability or failure on the part of the Company or the Guarantor to perform any agreement herein or to comply with any provision hereof, the Company and the Guarantor, jointly and severally, hereby agree to reimburse the Representatives and the other Underwriters (or such Underwriters as have terminated this Agreement with respect to themselves), severally, upon demand for all documented out-of-pocket expenses that shall have been reasonably incurred by the Representatives and the other Underwriters in connection with the proposed purchase and the offering and sale of the Securities, including, but not limited to, fees and disbursements of counsel, printing expenses, travel expenses, postage, facsimile and telephone charges.

SECTION 7. Effectiveness of this Agreement. This Agreement shall not become effective until the execution of this Agreement by the parties hereto.

SECTION 8. Indemnification and Contribution.

a) Indemnification of the Underwriters. The Company and the Guarantor, jointly and severally, hereby agree to indemnify and hold harmless each Underwriter, its directors, officers, employees, Affiliates (as defined in Rule 405) and agents and each person, if any, who controls any Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages or liabilities to which any Underwriter or such controlling person may become subject under the Securities Act, the Exchange Act or otherwise, insofar as any such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon the following:

(i) any untrue statement or alleged untrue statement made by the Company or the Guarantor in Section 1;

(ii) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or any amendment thereto, or the omission or alleged omission to state in the Registration Statement or any amendment thereto a material fact required to be stated therein or necessary to make the statements therein not misleading; or

(iii) any untrue statement or alleged untrue statement of any material fact included in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Additional Written Communication, the Disclosure Package or the Prospectus or any amendment or supplement thereto, or the omission or alleged omission to state in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Additional Written Communication, the Disclosure Package or the Prospectus or any amendment or supplement thereto a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading;

and will reimburse each indemnified party for any legal or other expenses incurred by them in connection with investigating, defending against, settling, compromising or appearing as a third-party witness in connection with any such loss, claim, damage, liability or action; provided, however, the Company and the Guarantor will not be liable in any such case to the extent that any such loss, claim, damage, or liability arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Additional Written Communication, the Disclosure Package or the Prospectus or any amendment or supplement thereto made in reliance upon and in conformity with information concerning the Underwriters furnished to the Company and the Guarantor in writing by any of the Underwriters through the Representatives expressly for use therein, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the information described as such in Section 8(b). The indemnity provided for in this Section 8(a) will be in addition to any liability that the Company or the Guarantor may otherwise have to the indemnified parties. Neither the Company nor the Guarantor shall be liable under this Section 8(a) for any settlement of any claim or action effected without its prior written consent, which shall not be unreasonably withheld.

b) Indemnification of the Company and the Guarantor. Each Underwriter, severally and not jointly, agrees to indemnify and hold harmless each of the Company and the Guarantor, their respective directors, officers, employees, Affiliates and agents and each person, if any, who controls the Company or the Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act against any losses, claims, damages

or liabilities to which each indemnified party may become subject under the Securities Act, the Exchange Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon (i) any untrue statement or alleged untrue statement of any material fact contained in the Registration Statement or any amendment thereto, or the omission or alleged omission to state in the Registration Statement or any amendment thereto a material fact required to be stated therein or necessary to make the statements therein not misleading or (ii) any untrue statement or alleged untrue statement of material fact included in any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Additional Written Communication, the Disclosure Package or the Prospectus or any amendment or supplement thereto, or the omission or alleged omission therefrom of a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading, in each case of clause (i) or (ii) above, 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 information concerning such Underwriter furnished to the Company and the Guarantor in writing by such Underwriter through the Representatives expressly for use therein and, subject to the limitation set forth immediately preceding this clause, will reimburse, any legal or other expenses incurred by each indemnified party in connection with investigating or defending against, settling, compromising or appearing as a third party witness in connection with any such loss, claim, damage, liability or action in respect thereof. Each of the Company and the Guarantor hereby acknowledges that the only information furnished to the Company and the Guarantor in writing by any Underwriter through the Representatives expressly for use in the Registration Statement, any Preliminary Prospectus, any Issuer Free Writing Prospectus, any Additional Written Communication, the Disclosure Package or the Prospectus or any amendment or supplement thereto are the statements set forth in (i) the first paragraph under the caption “Underwriting—Commissions and Discounts” in the Pricing Preliminary Prospectus and the Prospectus and (ii) the third sentence of the first paragraph under the caption “Underwriting—New Issue of Notes” in the Pricing Preliminary Prospectus and the Prospectus. The indemnity provided for in this Section 8(b) will be in addition to any liability that the Underwriters may otherwise have to the indemnified parties. The Underwriters shall not be liable under this Section 8(b) for any settlement of any claim or action effected without their consent, which shall not be unreasonably withheld.

c) Notifications and Other Indemnification Procedures; Settlements. Promptly after receipt by an indemnified party under this Section 8 of notice of the commencement of any action for which such indemnified party is entitled to indemnification under this Section 8, such indemnified party will, if a claim in respect thereof is to be made against an indemnifying party under this Section 8, notify the indemnifying party of the commencement thereof in writing, but the omission to so notify the indemnifying party (i) will not relieve it from any liability under paragraph (a) or (b) above unless and to the extent such failure results in the forfeiture by the indemnifying party of substantial rights and defenses and (ii) will not, in any event, relieve the indemnifying party from any obligations to any indemnified party other than the indemnification obligation provided in paragraphs (a) and (b) above. 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 reasonably satisfactory to such indemnified party; provided, however, that if (i) the use of counsel chosen by the indemnifying party to represent the indemnified party would present such counsel with an actual or a potential conflict of interest, (ii) the defendants in any such action include both the indemnified party and the indemnifying party and the indemnified party shall have been advised by counsel that there may be one or more legal defenses available to it and/or other indemnified parties that are different from or additional to those available to the indemnifying party, or (iii) the indemnifying party shall not have employed counsel reasonably satisfactory to the indemnified party to represent the indemnified party within a reasonable time after receipt by the indemnifying party of notice of the institution of such action, then, in each such case, the indemnifying party shall not have the right to assume the defense of such action on behalf of such indemnified party or parties and such indemnified party or parties shall have the right to select separate counsel to defend such action on behalf of such indemnified party or parties. After notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof and approval by such indemnified party of counsel appointed to defend such action, the indemnifying party will not be liable to such indemnified party under this Section 8 for any legal or other expenses, other than reasonable costs of investigation, subsequently incurred by such indemnified party in connection with the defense thereof, unless (i) the indemnified party shall have employed separate counsel in accordance with the proviso to the immediately preceding sentence (it being understood, however, that in connection with such action the indemnifying party shall not be liable for the expenses of more than one separate counsel (in addition to local counsel) in any one action or separate but substantially similar actions in the same jurisdiction arising out of the same general allegations

or circumstances, designated by the Representatives in the case of paragraph (a) of this Section 8 or the Guarantor in the case of paragraph (b) of this Section 8, representing the indemnified parties under such paragraph (a) or paragraph (b), as the case may be, who are parties to such action or actions) or (ii) the indemnifying party has authorized in writing the employment of counsel for the indemnified party at the expense of the indemnifying party. All fees and expenses reimbursed pursuant to this paragraph (c) shall be reimbursed as they are incurred. After such notice from the indemnifying party to such indemnified party, the indemnifying party will not be liable for the costs and expenses of any settlement of such action effected by such indemnified party without the prior written consent of the indemnifying party (which consent shall not be unreasonably withheld), unless such indemnifying party waived in writing its rights under this Section 8, in which case the indemnified party may effect such a settlement without such consent. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement or compromise of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party, or indemnity could have been sought hereunder by any indemnified party, unless such settlement (A) includes an unconditional written release of the indemnified party, in form and substance reasonably satisfactory to the indemnified party, from all liability on claims that are the subject matter of such proceeding and (B) does not include any statement as to an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

d) Contribution. In circumstances in which the indemnity agreement provided for in the preceding paragraphs of this Section 8 is unavailable to, or insufficient to hold harmless, an indemnified party in respect of any losses, claims, damages or liabilities (or actions in respect thereof), each indemnifying party, in order to provide for just and equitable contribution, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect (i) the relative benefits received by the indemnifying party or parties, on the one hand, and the indemnified party, on the other hand, from the offering and sale of the Securities or (ii) if the allocation provided by the foregoing clause (i) is not permitted by applicable law, not only such relative benefits but also the relative fault of the indemnifying party or parties, on the one hand, and the indemnified party, on the other hand, in connection with the statements or omissions or alleged statements or omissions that resulted in such losses, claims, damages or liabilities (or actions in respect thereof). The relative benefits received by the Company and the Guarantor, on the one hand, and the Underwriters, on the other hand, shall be deemed to be in the same proportion as the total proceeds from the offering and sale of the Securities (before deducting expenses) received by the Company bear to the total discounts and commissions received by such Underwriters. The relative fault of the parties shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company or the Guarantor, on the one hand, or the Underwriters, on the other hand, the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission or alleged statement or omission, and any other equitable considerations appropriate in the circumstances. The Company, the Guarantor and the Underwriters 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) or by any other method of allocation that does not take into account the equitable considerations referred to in the first sentence of this paragraph (d). Notwithstanding any other provision of this paragraph (d), no Underwriter shall be obligated to make contributions hereunder that in the aggregate exceed the total discounts, commissions and other compensation received by such Underwriter in connection with the Notes underwritten by it under this Agreement and distributed to the public, less the aggregate amount of any damages that such Underwriter has otherwise been required to pay, and no person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The Underwriters’ obligation to contribute pursuant to this Section are several, and not joint, in proportion to their respective underwriting commitments as set forth opposite their names in Schedule A. For purposes of this paragraph (d), each Underwriter’s directors, officers, employees, Affiliates and agents and each person, if any, who controls an Underwriter within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Underwriters, and each officer of the Company or the Guarantor that signed the Registration Statement, each director of the Company or the Guarantor and each person, if any, who controls the Company or the Guarantor within the meaning of Section 15 of the Securities Act or Section 20 of the Exchange Act shall have the same rights to contribution as the Company and the Guarantor.

SECTION 9. Default of One or More of the Several Underwriters. If, on the Closing Date, any one or more of the several Underwriters shall fail or refuse to purchase Notes that it or they have agreed to purchase

hereunder on such date, and the aggregate principal amount of Notes that such defaulting Underwriter or Underwriters agreed but failed or refused to purchase does not exceed 10% of the aggregate principal amount of the Notes to be purchased on such date, the other Underwriters shall be obligated, severally, in the proportion that the aggregate principal amount of such Notes set forth opposite their respective names on Schedule A bears to the aggregate principal amount of such Notes set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as may be specified by the Representatives with the consent of the non-defaulting Underwriters, to purchase such Notes which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date. If, on the Closing Date, any one or more of the Underwriters shall fail or refuse to purchase such Notes and the aggregate principal amount of such Notes with respect to which such default occurs exceeds 10% of the aggregate principal amount of Notes to be purchased on such date, and arrangements satisfactory to the Representatives and the Company for the purchase of such Notes are not made within 48 hours after such default, this Agreement shall terminate without liability of any party to any other party except that the provisions of Sections 4, 6, 8 and 16 shall at all times be effective and shall survive such termination. In any such case, either the Representatives or the Company and the Guarantor shall have the right to postpone the Closing Date, but in no event for longer than seven days in order that the required changes, if any, to the Registration Statement, the Disclosure Package or the Prospectus or any other documents or arrangements may be effected.

As used in this Agreement, the term “Underwriter” shall be deemed to include any person substituted for a defaulting Underwriter under this Section 9. Any action taken under this Section 9 shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

SECTION 10. Termination of this Agreement. Prior to the Closing Date, this Agreement may be terminated by the Representatives by notice given to the Company or the Guarantor if at any time (i) trading or quotation in any of the Guarantor’s securities shall have been suspended or limited by the Commission, the SIX Swiss Exchange, the NASDAQ OMX Stockholm Exchange or the New York Stock Exchange, or trading in securities generally on the Nasdaq Stock Market, the NASDAQ OMX Stockholm Exchange, the New York Stock Exchange or the SIX Swiss Exchange shall have been suspended or limited, or minimum or maximum prices shall have been generally established on any of such stock exchanges; (ii) a general banking moratorium shall have been declared by any of United States, New York or Switzerland authorities; (iii) there shall have occurred any outbreak or escalation of national or international hostilities or any crisis or calamity involving the United States or Switzerland, or any change in the United States, Swiss or international financial markets, or any substantial change or development involving a prospective substantial change in United States’, Switzerland’s or international political, financial or economic conditions, as in the sole judgment of the Representatives is material and adverse and makes it impracticable or inadvisable to market the Securities in the manner and on the terms described in the Registration Statement, the Disclosure Package and the Prospectus or to enforce contracts for the sale of the Securities; (iv) in the sole judgment of the Representatives, there shall not have occurred any event or development that, individually or in the aggregate, has had, or would be reasonably likely to have, a Material Adverse Effect (including, without limitation, a change in control of the Company or the Guarantor), except as disclosed in the Registration Statement, the Disclosure Package and the Prospectus; or (v) there shall have occurred a material disruption in commercial banking or securities settlement or clearance services in the jurisdictions where the Securities are offered. Any termination pursuant to this Section 10 shall be without liability of any party to any other party except as provided in Sections 4 and 6, and provided further that Sections 4, 6, 8 and 16 shall survive such termination and remain in full force and effect.

SECTION 11. No Fiduciary Duty. Each of the Company and the Guarantor acknowledges and agrees that: (i) the purchase and sale of the Securities pursuant to this Agreement, including the determination of the public offering price of the Notes and any related discounts and commissions, is an arm’s-length commercial transaction between the Company and the Guarantor, on the one hand, and the several Underwriters, on the other hand, and each of the Company and the Guarantor is capable of evaluating and understanding and understands and accepts the terms, risks and conditions of the transactions contemplated by this Agreement; (ii) in connection with the transactions contemplated by this Agreement and the process leading to such transactions, each Underwriter is and has been acting solely as a principal and is not the financial advisor, agent or fiduciary of the Company or the Guarantor or their respective Affiliates, stockholders, creditors or employees or any other party; (iii) no Underwriter has assumed or will assume an advisory, agency or fiduciary responsibility in favor of the Company or the Guarantor with respect to any of the transactions contemplated by this Agreement or the process leading thereto (irrespective of whether such Underwriter has advised or is currently advising the Company or the Guarantor on

other matters) and no Underwriter has any obligation to the Company or the Guarantor with respect to the offering of the Securities except the obligations expressly set forth in this Agreement; (iv) the several Underwriters and their respective Affiliates may be engaged in a broad range of transactions that involve interests that differ from those of the Company or the Guarantor and that the several Underwriters have no obligation to disclose any of such interests by virtue of any advisory, agency or fiduciary relationship; and (v) the Underwriters have not provided any legal, accounting, regulatory or tax advice with respect to the offering of the Securities and each of the Company and the Guarantor has consulted its own legal, accounting, regulatory and tax advisors to the extent it deemed appropriate.

This Agreement supersedes all prior agreements and understandings (whether written or oral) between the Company and the Guarantor, on the one hand, and the several Underwriters, on the other hand, with respect to the subject matter hereof. Each of the Company and the Guarantor hereby waives and releases, to the fullest extent permitted by law, any claims it may have against the several Underwriters with respect to any breach or alleged breach of agency or fiduciary duty.

SECTION 12. Representations and Indemnities to Survive Delivery. The respective indemnities, agreements, representations, warranties and other statements of each of the Company and the Guarantor, of their respective officers and of the several Underwriters set forth in or made pursuant to this Agreement (i) will remain operative and in full force and effect, regardless of any (A) investigation, or statement as to the results thereof, made by or on behalf of any Underwriter, the officers or employees of any Underwriter, or any person controlling the Underwriter, the Company or the Guarantor, the officers or employees of the Company or the Guarantor, or any person controlling the Company or the Guarantor, as the case may be or (B) acceptance of the Securities and payment for them hereunder and (ii) will survive delivery of and payment for the Securities sold hereunder and any termination of this Agreement.

SECTION 16. Governing Law Provisions. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED AND INTERPRETED IN ACCORDANCE WITH, THE INTERNAL LAWS OF THE STATE OF NEW YORK APPLICABLE TO AGREEMENTS MADE AND TO BE PERFORMED IN THAT STATE.

a) Consent to Jurisdiction. Any legal suit, action or proceeding arising out of or based upon this Agreement or the transactions contemplated hereby (“Related Proceedings”) may be instituted in the federal courts of the United States or the courts of the State of New York, in each case located in the Borough of Manhattan in The City of New York (collectively, the “Specified Courts”), and each party irrevocably submits to the exclusive jurisdiction (except for proceedings instituted in regard to the enforcement of a judgment of any such court (a “Related Judgment”), as to which such jurisdiction is non-exclusive) of the Specified Courts in any such suit, action or proceeding. Service of any process, summons, notice or document by mail to such party’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any Specified Court. The parties irrevocably and unconditionally waive any objection to the laying of venue of any suit, action or other proceeding in the Specified Courts and irrevocably and unconditionally waive and agree not to plead or claim in any Specified Court that any such suit, action or other proceeding brought in any such court has been brought in an inconvenient forum. The Guarantor irrevocably appoints CT Corporation System, acting through its office at 111 Eighth Avenue, 13th Floor, New York, New York 10011, as its agent to receive service of process or other legal summons (in such capacity, the “Process Agent”) for purposes of any such suit, action or proceeding that may be instituted in any Specified Court. If for any reason the Process Agent shall cease to be available to act in the above-

mentioned capacity, the Guarantor agrees to appoint a new agent for service of process in The City of New York on the terms and for the purposes of this Section 16 satisfactory to the Underwriters. Notwithstanding that service of any process, summons, notice or document by mail to the Guarantor’s address set forth above shall be effective service of process for any suit, action or other proceeding brought in any Specified Court, the Guarantor further consents and agrees that service of any such process, summons, notice or document for any such suit, action or proceeding on the Process Agent or any such new agent for service of process (whether or not the appointment of the Process Agent or such new agent shall for any reason prove to be ineffective or the Process Agent shall accept or acknowledge such service) shall be effective service of process on the Guarantor for any such suit, action or proceeding. The Guarantor further agrees that the failure of the Process Agent or any such new agent to give any notice of such service to it shall not impair or affect in any way the validity of such service or any judgment rendered in any suit, action or proceeding based thereon.

b) Waiver of Immunity. With respect to any Related Proceeding, the Guarantor irrevocably waives, to the fullest extent permitted by applicable law, all immunity (whether on the basis of sovereignty or otherwise) from jurisdiction, service of process, attachment (both before and after judgment) and execution to which it might otherwise be entitled in the Specified Courts, and with respect to any Related Judgment, the Guarantor waives any such immunity in the Specified Courts or any other court of competent jurisdiction, and will not raise or claim or cause to be pleaded any such immunity at or in respect of any such Related Proceeding or Related Judgment, including, without limitation, any immunity pursuant to the United States Foreign Sovereign Immunities Act of 1976, as amended.

Section 17. Research Analyst Independence; Other Relationships. Each of the Company and the Guarantor acknowledges that the Underwriters’ research analysts and research departments are required to be independent from their respective investment banking divisions and are subject to certain regulations and internal policies, and that such Underwriters’ research analysts may hold views and make statements or investment recommendations and/or publish research reports with respect to the Guarantor or any of its subsidiaries (including the Company) and/or the offering of the Securities that differ from the views of their respective investment banking divisions. Each of the Company and the Guarantor hereby waives and releases, to the fullest extent permitted by law, any claims that the Company or the Guarantor may have against the Underwriters with respect to any conflict of interest that may arise from the fact that the views expressed by their independent research analysts and research departments may be different from or inconsistent with the views or advice communicated to the Company and the Guarantor by such Underwriters’ investment banking divisions. Each of the Company and the Guarantor acknowledges that each of the Underwriters is a full service securities firm and as such, in the ordinary course of their business activities, each of the Underwriters and their Affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of the Company or the Guarantor or their Affiliates. Each of the Company and the Guarantor acknowledges that the Underwriters and their Affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments. Certain of the Underwriters or their Affiliates that have a lending relationship with the Guarantor routinely hedge their credit exposure to the Guarantor, consistent with their customary risk management policies. Typically, such Underwriters and their Affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in securities, including potentially the Securities. Any such short positions could adversely affect future trading prices of the Securities.

SECTION 18. General Provisions. This Agreement may be executed in two or more counterparts, each one of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. This Agreement may not be amended or modified unless in writing by all of the parties hereto, and no condition herein (express or implied) may be waived unless waived in writing by each party whom the condition is meant to benefit. The Section headings herein are for the convenience of the parties only and shall not affect the construction or interpretation of this Agreement.

Each of the parties hereto acknowledges that it is a sophisticated business person who was adequately represented by counsel during negotiations regarding the provisions hereof, including, without limitation, the indemnification and contribution provisions of Section 8, and is fully informed regarding said provisions.

The Issuer and the Guarantor have filed a registration statement (including a prospectus) with the Securities and Exchange Commission (the “SEC”) for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents the Issuer and the Guarantor have filed with the SEC for more complete information about the Issuer, the Guarantor 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, the Guarantor, any underwriter or any dealer participating in the offering will arrange to send you the prospectus if you request it by calling Citigroup toll-free at 1-800-831-9146, Credit Suisse toll-free at 1-800-221-1037 and J.P.

Solely for the purposes of each manufacturer’s product approval process, the target market assessment in respect of the Notes has led to the conclusion that: (i) the target market for the notes is eligible counterparties and professional clients only, each as defined in Directive 2014/65/EU (as amended, “MiFID II”); and (ii) all channels for distribution to eligible counterparties and professional clients are appropriate. Any person subsequently offering, selling or recommending the Notes (a “distributor”) should take into consideration the manufacturers’ target market assessment; however, a distributor subject to MiFID II is responsible for undertaking its own target market assessment in respect of the Notes (by either adopting or refining the manufacturers’ target market assessment) and determining appropriate distribution channels.

ANY DISCLAIMER OR OTHER NOTICE THAT MAY APPEAR BELOW IS NOT APPLICABLE TO THIS COMMUNICATION AND SHOULD BE DISREGARDED. SUCH DISCLAIMER OR NOTICE WAS AUTOMATICALLY GENERATED AS A RESULT OF THIS COMMUNICATION BEING SENT BY BLOOMBERG OR ANOTHER EMAIL SYSTEM.
