Section 2.6 Payment of Additional Amounts.

(a) Obligation and Exceptions. All payments by or on behalf of the Company under the Notes of any series shall be made free and clear of, and without withholding or deduction for taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or within Switzerland or any authority therein or thereof having power to tax (“Swiss Taxes”), unless such withholding or deduction is required by law.

If the withholding or deduction of Swiss Taxes in respect of payments made by or on behalf of the Company under the Notes of any series is required by law, the Company will pay such additional amounts (“Additional Amounts”) as may be necessary in order that the net amount received by each Holder of a Note of such series after such withholding or deduction is equal to the amount that would have been received in respect of such Note in the absence of such withholding or deduction; provided, however, that no such Additional Amounts shall be payable in respect of any such Note:

(i) to, or to a third party on behalf of, a Holder or another beneficiary of the Note, which is liable for such Swiss Taxes in respect of such payment under the Note by reason of his having some connection with the jurisdiction by which such Swiss Taxes have been imposed, levied, collected, withheld or assessed other than the mere benefit under the Note;

(ii) where the Note is presented or surrendered for payment more than 30 days after the Relevant Date, except to the extent that the relevant Holder would have been entitled to Additional Amounts on presenting or surrendering the Note for payment on the last day of the period of 30 days assuming that day to have been a day on which the Holder of such Note is entitled to receive payment in accordance with the Note and this Indenture;

(iii) to, or to a third party on behalf of, a Holder or another beneficiary of the Note who is able to avoid or reduce such withholding or deduction by complying with any requirement to present any form, certificate or documentation and/or make a declaration of identity, nationality, non-residence, connection (or lack thereof) to, or other similar claim with respect to the relevant tax authority as a precondition to exemption or relief from such Swiss Taxes, or to the extent that a Holder or another beneficiary of the Note is able to credit or obtain a refund for such Swiss Taxes;

(iv) where such deduction or withholding is imposed on a payment pursuant to laws enacted by Switzerland providing for the taxation of payments according to principles similar to those laid down in the draft legislation proposed by the Swiss Federal Council on December 17, 2014, altering the debtor-based Swiss federal withholding tax system to a paying-agent system where a Person other than the Company withholds or deducts tax;

(v) where the Note is presented for payment by or on behalf of a Holder who would have been able to avoid such withholding or deduction (A) by presenting the Note to another Paying Agent, or (B) by authorizing the Paying Agent to report information in accordance with the procedure laid down by the relevant tax authority or by producing, in the form required by the relevant tax authority, a declaration, claim, certificate, document or other evidence establishing exemption therefrom;

(vi) in respect of any estate, inheritance, gift, sales, excise, transfer, wealth or personal property tax or any similar tax, duty, assessment or governmental charge;

(vii) in respect of any Swiss Taxes that are payable otherwise than by withholding or deduction by the Company or by a Paying Agent, from the payment of the amount payable in respect of the Note;

(viii) in respect of any tax, duty, assessment or governmental charge imposed or withheld pursuant to Sections 1471 through 1474 of the U.S. Internal Revenue Code of 1986, as amended (the “Code”), as of the issue date (or any amended or successor version of such sections), any regulations promulgated thereunder, any official interpretations thereof, any similar law or regulation adopted pursuant to an intergovernmental agreement between a non-U.S. jurisdiction and the United States with respect to the foregoing or any agreements entered into pursuant to Section 1471(b)(1) of the Code; or

(ix) in respect of any combination of taxes, duties, assessments or other governmental charges referred to in the preceding clauses (i) through (viii) above.

(b) Swiss Draft Legislation. If legislation is enacted providing for the taxation of payments according to principles similar to those laid down in the draft legislation proposed by the Swiss Federal Council referred to above, the Company will use its reasonable efforts to make payments in respect of the Notes through a Paying Agent outside Switzerland, provided that the use of such Paying Agent outside Switzerland would eliminate any Swiss withholding tax that would otherwise apply to payments by the Company.

(c) No Express Mention of Additional Amounts Not Exclusion Thereof. Whenever in the Indenture, this First Supplemental Indenture or the Notes there is mentioned, in any context, the payment of principal, premium, if any, or interest or any other amount payable under or with respect to any Note, such mention shall be deemed to include mention of the payment of Additional Amounts to the extent that, in such context, Additional Amounts are, were or would be payable in respect thereof, and express mention of the payment of Additional Amounts in any provision of the Indenture, this First Supplemental Indenture or the Notes shall not be construed as excluding Additional Amounts in those provisions of the Indenture, this First Supplemental Indenture or the Notes where such express mention is not made.

Section 2.7 Optional Tax Redemption.

(a) Redemption Price and Conditions. The Company or a successor Person to the Company may redeem the Notes of any series prior to maturity, at its option, in whole but not in part, at a Redemption Price equal to 100% of their principal amount plus unpaid interest accrued thereon to, but not including, the Redemption Date, if, as a result of:

(i) any change in, or amendment to, the laws or treaties (or any regulations, protocols or rulings promulgated thereunder) of the Tax Jurisdiction affecting taxation; or

(ii) any change in the existing official position or the stating of an official position regarding the application or interpretation of such laws, treaties, regulations or rulings (including a holding, judgment or order by a court of competent jurisdiction or a change in published administrative practice),

which change or amendment becomes effective (or with respect to official position, is announced) on or after the date of issuance of the Notes of the applicable series (or, if the relevant Tax Jurisdiction was not a Tax Jurisdiction on such date, the date on which such Tax Jurisdiction became a Tax Jurisdiction hereunder), the Company or the Guarantor is, or on the next succeeding Interest Payment Date will be, obligated to pay any Additional Amounts in respect of taxes on any payment made or to be made by the Company under the Notes of the applicable series or by the Guarantor under the Guarantee, and such requirement cannot be avoided by the taking of reasonable measures by the Company or the Guarantor, as applicable (provided that changing the jurisdiction of the Company or the Guarantor is not a reasonable measure for purposes of this section). Notwithstanding the foregoing, the Company will pay any interest installment due on an Interest Payment Date that falls on or prior to the Redemption Date to the Holders as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date.

Notice of any redemption will be sent at least 30 days but not more than 60 days prior to the Redemption Date to each Holder of the Notes of the applicable series to be redeemed. If the Company has provided proper notice to Holders of such Notes, then, unless the Company defaults in payment of the Redemption Price, on and after the Redemption Date interest will cease to accrue on such Notes.

(b) Deliverables. Prior to the delivery of any notice of redemption of the Notes of any series in connection with a redemption under this Section 2.7, the Company or the Guarantor, as the case may be, will deliver to the Trustee at least 5 days but not more than 30 days before the mailing of any such notice of redemption of the Notes, an Officers’ Certificate stating that a change or amendment referred to in the prior paragraph has occurred and that the requirement to pay Additional Amounts cannot be avoided by taking reasonable measures available to the Company or the Guarantor, as the case may be. The Trustee will accept such certificate as sufficient evidence of the satisfaction of the conditions precedent described above, in which event it will be conclusive and binding on the Holders of the Notes of such series.

CUSIP: 00037B AD4
ISIN: US00037BAD47

ABB FINANCE (USA) INC., a Delaware corporation (herein called the “Company,” which term includes any successor Person or Substituted Debtor under the Indenture hereinafter referred to), for value received, hereby promises to pay to CEDE & CO., or registered assigns, the principal amount of [ · ] DOLLARS ($[ · ]) on April 3, 2020 (the “Stated Maturity Date”) (unless redeemed on any date fixed for redemption (the “Redemption Date”) prior to the Stated Maturity Date in accordance with the terms of this Note and the Indenture) (the Stated Maturity Date and the Redemption Date is hereinafter referred to as the “Maturity Date” with respect to the principal repayable on such date) and to pay interest on the outstanding principal amount of this Note from [April 3, 2018](1) or from the most recent Interest Payment Date to which interest has been paid or duly provided for semi-annually in arrears on April 3 and October 3, commencing on [October 3, 2018] (2) (each, an “Interest Payment Date”), and on the Maturity Date, at the rate of 2.800% per annum, until said principal amount is paid or duly provided for. Interest on this Note will be computed on the basis of a 360-day year consisting of twelve 30-day months.

Payment of Interest. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date, will, as provided in the Indenture, be paid, in immediately available funds, to the Person in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on the March 19 and September 18, as the case may be, immediately preceding such Interest Payment Date (the “Regular Record Date”). Any such interest not punctually paid or duly provided for on an Interest Payment Date (“Defaulted Interest”) will forthwith cease to be payable to the Holder on such Regular Record Date, and such Defaulted Interest may be paid to the Person in whose name this Note (or one or more Predecessor Notes) is registered at the close of business on a special record date (the “Special Record Date”) for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Notes not less than 10 days prior to such Special Record Date, or may be paid at any time in any other lawful manner, all as more fully provided in the Indenture.

Place of Payment. Payment of principal of, and premium, if any, and interest on, and any Additional Amounts with respect to, this Note will be made at the Corporate Trust Office of the Trustee or such other Office or Agency as may be designated by the Company for such purpose in The City of New York, in Dollars; provided, however, that the Company will make payment of principal of, and premium, if any, and interest on, and any Additional Amounts with respect to, this Note due on the Maturity Date by wire transfer of immediately available funds against presentation and surrender at such Office or Agency, if appropriate written wire transfer

(2) Insert appropriate date in the case of a re-opening of the Notes.

instructions are received by the Trustee not less than 15 days prior to the Maturity Date. In the event that such instructions are not so received, such amounts will be paid by check against such presentation and surrender. The Company may, at its option, make payments of interest on an Interest Payment Date other than the Maturity Date by check mailed to each Holder of Notes entitled to receive such payment or, if appropriate written wire transfer instructions are received by the Trustee not less than 15 days prior to such Interest Payment Date, by wire transfer of immediately available funds to an account maintained by such Holder located in the United States.

Time of Payment. If an Interest Payment Date or the Maturity Date falls on a day that is not a Business Day, the required payment need not be made on such date, but may be made on the next succeeding Business Day with the same force and effect as if made on such Interest Payment Date or the Maturity Date, as the case may be, and no additional interest shall accrue on such payment as a result of payment on such next succeeding Business Day.

General. This Note is one of a duly authorized issue of Securities of the Company, issued and to be issued in one or more series under an indenture (the “Base Indenture”), dated as of April 3, 2018, among the Company, ABB Ltd, as guarantor (the “Guarantor”), and Deutsche Bank Trust Company Americas, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture with respect to the series of which this Note is a part), as supplemented by a First Supplemental Indenture thereto, dated as of April 3, 2018 (the “First Supplemental Indenture,” and together with the Base Indenture, the “Indenture”), among the Company, the Guarantor and the Trustee. Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Note is one of a duly authorized series of Securities designated as “2.800% Notes due 2020” (collectively, the “Notes”), limited, except as specified below, in aggregate principal amount to THREE HUNDRED MILLION DOLLARS ($300,000,000). To the extent the terms of this Note conflict with the terms of the Indenture, the terms of this Note shall govern.

Further Issuance. The Company may, from time to time, without notice to, or the consent of, the Holders of the Notes, issue additional Securities ranking equally and ratably with and having the same interest rate, maturity and other terms as the originally issued Notes (other than issue date and, to the extent applicable, issue price, initial Interest Payment Date and initial date of interest accrual). Any such additional Securities, if the Company so determines, will be consolidated, and constitute a single series of Securities, with the originally issued Notes for all purposes; provided, however, that any such additional Securities that have the same CUSIP, ISIN or other identifying number of any Outstanding Notes must be fungible with such Outstanding Notes for U.S. federal income tax purposes.

Events of Default. If an Event of Default with respect to the Notes shall have occurred and be continuing, the principal of the Notes may be declared, and in certain cases shall automatically become, due and payable in the manner and with the effect provided in the Indenture.

Sinking Fund. The Notes are not subject to any sinking fund.

Optional Make-Whole Redemption. The Company may redeem the Notes prior to the Stated Maturity Date, at its option, at any time in whole or from time to time in part, upon not less than 30 nor more than 60 days’ prior written notice to each Holder of Notes, at the Make-Whole Amount, plus (i) unpaid interest, if any, accrued on the principal amount of the Notes being redeemed to, but not including, the Redemption Date and (ii) Additional Amounts, if any. Notwithstanding the foregoing, the Company will pay any interest installment due on an Interest Payment Date which occurs on or prior to the Redemption Date to the Holders of Notes as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date. In the case of any partial redemption, selection of the Notes for redemption will be made by the Trustee by such methods, as the Trustee shall deem fair and appropriate. If any Note is to be redeemed in part only, the notice of redemption relating to such Note shall state the portion of the principal amount thereof to be redeemed. A new Note in principal amount equal to the unredeemed portion thereof will be issued in the name of the Holder thereof upon cancellation of this Note.

Payment of Additional Amounts. Subject to certain exceptions set forth in the First Supplemental Indenture and the Guarantee, as the case may be, if the withholding or deduction of taxes, duties, assessments or governmental charges of whatever nature imposed, levied, collected, withheld or assessed by or within Switzerland or any authority thereof or therein having power to tax in respect of any payments by or on behalf of the Company under this Note or the Guarantor under the Guarantee is required by law, the Company or the Guarantor, as applicable, shall pay to the Holder thereof, pursuant to the Indenture and this Note or the Guarantee, as the case may be, such Additional Amounts as may be necessary in order that the net amount received by the Holder of this Note after such withholding or deduction is equal to the amount that would have been receivable in respect of this Note in the absence of such withholding or deduction. Under the Indenture, a successor Person to the Company (including a Substituted Debtor) or the Guarantor, as applicable, that is organized in the United States (in the case of a successor Person to the Company) or Switzerland (in the case of a successor Person to the Guarantor) or any political subdivision or governmental authority thereof or therein, will be subject to the obligation referred to in the preceding sentence. In addition, any such successor Person (i) that is not organized under the laws of the United States of America, any state thereof or the District of Columbia or any territory thereof, and (ii) in the case of a successor Person to the Guarantor, that is not organized under the laws of Switzerland or any political subdivision or governmental authority thereof is, in connection with such succession, required to agree to make all payments in respect of the Outstanding Notes free and clear of, and without withholding or deduction for, or on account of, any present or future taxes, duties, assessments or other governmental charges of whatever nature imposed, collected, withheld, assessed or levied by or on behalf of the jurisdiction of organization or residence (for tax purposes) of such successor Person or any political subdivision or governmental authority thereof or therein having the power to tax, unless required by law, in which case such successor Person shall also be required to agree, subject to certain customary exceptions, to pay such additional amounts as may be necessary in order that the net amount received by each Holder of Outstanding Notes after such withholding or deduction is equal to the amount that would have been receivable in respect of each such Note in the absence of such withholding or deduction.

Redemption Date and (ii) Additional Amounts, if any, in the event that the Company or the Guarantor has become or would become obligated to pay, on the next date on which any amount would be payable with respect to the Notes, any Additional Amounts as a result of certain changes or amendments to the laws, treaties or official positions of the relevant Tax Jurisdiction, as set forth in the First Supplemental Indenture, and the Company or the Guarantor, as applicable, cannot avoid such obligation by taking reasonable measures available to it. Notwithstanding the foregoing, the Company shall pay any interest installment due on an Interest Payment Date which occurs on or prior to the Redemption Date to the Holders of Notes as of the close of business on the Regular Record Date immediately preceding such Interest Payment Date.

Satisfaction and Discharge. The Indenture contains provisions where, upon the Company’s direction and satisfaction of certain conditions, the Indenture shall cease to be of further effect with respect to the Notes, subject to the survival of specified provisions of the Indenture, including the Company’s obligation to pay Additional Amounts (and the Guarantor’s obligation under the Guarantee to pay Additional Amounts) in respect of such Notes to the extent described in the Indenture, which provisions apply to this Note.

Defeasance and Covenant Defeasance. The Indenture contains provisions for defeasance at any time of certain obligations of the Company under this Note and the Indenture, and certain obligations of the Guarantor under the Indenture.

Modification and Waivers; Obligations of the Company Absolute. The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the Guarantor and the rights of the Holders of the Securities. Such amendment and modification may be effected under the Indenture at any time by the Company, the Guarantor and the Trustee with the consent of the Holders of a majority in aggregate principal amount of the Outstanding Securities of each series affected thereby (voting as separate classes). The Indenture also contains provisions permitting the Holders of a majority in aggregate principal amount of the Outstanding Securities of any series, on behalf of the Holders of all Outstanding Securities of such series, to waive compliance by the Company with certain provisions of the Indenture. Furthermore, provisions in the Indenture permit the Holders of a majority in aggregate principal amount of the Outstanding Securities of any series to waive, on behalf of the Holders of all Outstanding Securities of such series, certain past defaults under the Indenture and their consequences. Any such consent or waiver in respect of the Notes shall be conclusive and binding upon the Holder of this Note and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange hereof or in lieu hereof, whether or not notation of such consent or waiver is made upon this Note.

No reference herein to the Indenture and no provision of this Note or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of, and premium, if any, and interest on, and any Additional Amounts with respect to, this Note at the time, place, and rate, and in the coin or currency, herein prescribed.

written request to institute proceedings in respect of an Event of Default from the holders of at least 25% in aggregate principal amount of the Outstanding Notes, as well as an offer of indemnity or security reasonably satisfactory to it, and no inconsistent direction has been given to the Trustee during such 60-day period by the Holders of a majority in aggregate principal amount of the Outstanding Notes. Notwithstanding any other provision of the Indenture, each Holder of a Note will have the right, which is absolute and unconditional, to receive payment of the principal of, and premium, if any, and interest on, and any Additional Amounts in respect of, such Note on the respective due dates therefor and to institute suit for the enforcement therefor, and this right shall not be impaired without the consent of such Holder.

Authorized Denominations. The Notes are issuable only in registered form without coupons in minimum denominations of $2,000 or any integral multiple of $1,000 in excess thereof.

Registration of Transfer or Exchange. As provided in the Indenture and subject to certain limitations herein and therein set forth, the transfer of this Note is registrable in the register of the Notes maintained by the Security Registrar upon surrender of this Note for registration of transfer, at the Office or Agency in any Place of Payment, duly endorsed by, or accompanied by a written instrument of transfer in form satisfactory to the Company and the Security Registrar, duly executed by the Holder hereof or his or her attorney duly authorized in writing, and thereupon one or more new Notes, of authorized denominations and for the same aggregate principal amount, will be issued to the designated transferee or transferees.

As provided in the Indenture and subject to certain limitations herein and therein set forth, this Note is exchangeable for a like aggregate principal amount of Notes of different authorized denominations, as requested by the Holders surrendering the same.

No service charge shall be made for any such registration of transfer or exchange, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.

Prior to due presentment of this Note for registration of transfer, the Company, the Trustee and any agent of the Company or the Trustee may treat the Holder as the owner hereof for all purposes, whether or not this Note be overdue, and none of the Company, the Trustee or any such agent shall be affected by notice to the contrary.

Guarantee. Payment of this Note is fully and unconditionally guaranteed by the Guarantor pursuant to the Guarantee issued pursuant to the Base Indenture. The Guarantee may be modified in accordance with the terms of the Base Indenture.

Defined Terms. All terms used in this Note, which are defined in the Indenture and are not otherwise defined herein, shall have the meanings assigned to them in the Indenture.

Governing Law. The Indenture and this Note shall be governed by, and construed in accordance with, the laws of the State of New York without regard to conflicts of law principles of such State other than New York General Obligations Law Section 5-1401.

General. This Note is one of a duly authorized issue of Securities of the Company, issued and to be issued in one or more series under an indenture (the “Base Indenture”), dated as of April 3, 2018, among the Company, ABB Ltd, as guarantor (the “Guarantor”), and Deutsche Bank Trust Company Americas, as trustee (herein called the “Trustee,” which term includes any successor trustee under the Indenture with respect to the series of which this Note is a part), as supplemented by a First Supplemental Indenture thereto, dated as of April 3, 2018 (the “First Supplemental Indenture,” and together with the Base Indenture, the “Indenture”), among the Company, the Guarantor and the Trustee.

Reference is hereby made to the Indenture for a statement of the respective rights, limitations of rights, obligations, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities, and of the terms upon which the Securities are, and are to be, authenticated and delivered.

To the extent the terms of this Note conflict with the terms of the Indenture, the terms of this Note shall govern.

principal of, and premium, if any, and interest on, and any Additional Amounts with respect to, this Note at the time, place, and rate, and in the coin or currency, herein prescribed.

Authorized Denominations. The Notes are issuable only in registered form without coupons in minimum denominations of $2,000 or any integral multiple of $1,000 in excess thereof.
