BANK OF BOSTON CORPORATION [SEAL] By: Name: Title: Attest: By: _________________________________ Name: Title: CERTIFICATE OF AUTHENTICATION This Note is one of the Securities referred to in the Senior Indenture referred to herein. NORWEST BANK MINNESOTA, NATIONAL ASSOCIATION By: The First National Bank of Boston, as Authenticating Agent By: ________________________ Dated: ______________ Name: Title: 5 6 [Reverse of Note] This Note is one of a duly authorized issue of Securities (hereinafter called the "Securities") of the Corporation designated as its Senior Medium-Term Notes (the "Notes"). The Notes are issued and to be issued under a Senior Indenture dated as of June 15, 1992 (herein the "Senior Indenture") between the Corporation and Norwest Bank Minnesota, National Association, Trustee (the "Trustee" which term shall include any duly appointed successor trustee acting in such capacity), to which Senior Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights thereunder of the Corporation, the Trustee and the Holders of the Securities and the terms upon which the Securities are, and are to be, authenticated and delivered. Copies of the Senior Indenture are on file and available for inspection at the offices of the Trustee located at 6th Street and Marquette Avenue, Minneapolis, Minnesota 55479 or at such other place or places the Trustee shall designate by notice to the person in whose name this Note is registered (the "Holder") on the Security Register (as defined below). The terms of individual Notes may vary with respect to interest rates or interest rate formulas, issue dates, maturity, redemption, repayment, currency of payment and otherwise. The Notes are issuable only in registered form without coupons in the Authorized Denominations specified on the face hereof. As provided in the Senior Indenture and subject to certain limitations therein set forth, the Notes are exchangeable for a like aggregate principal amount of Notes denominated as authorized, as requested by the Holder surrendering the same. Unless otherwise specified herein, payments of principal of and premium, if any, and interest on this Note are payable by the Corporation in the Specified Currency specified on the face hereof (or, if such Specified Currency is not at the time of such payment legal tender for the payment of public and private debts, in such other coin or currency of the country which issued such Specified Currency as at the time of such payment is legal tender for the payment of such debts). If the Specified Currency specified on the face hereof is other than United States dollars, any such amounts paid by the Corporation will be converted by the Exchange Rate Agent specified on the face hereof into United States dollars for payment to the Holder of this Note. If the Specified Currency on the face hereof is other than United States dollars, any United States dollar amount to be 6 7 received by the Holder of this Note will be based on the highest bid quotation in The City of New York received by the Exchange Rate Agent at approximately 11:00 a.m., New York City time, on the second Business Day preceding the applicable payment date from three recognized foreign exchange dealers (one of whom may be the Exchange Rate Agent) selected by the Exchange Rate Agent and approved by the Corporation for the purchase by the quoting dealer of the Specified Currency for United States dollars for settlement on such payment date in the aggregate amount of the Specified Currency payable to all Holders of Foreign Currency Notes denominated in a currency other than United States dollars scheduled to receive United States dollar payments and at which the applicable dealer commits to execute a contract. All currency exchange costs will be borne by the Holder of this Note by deductions from such payments. If three such bid quotations are not available, payments on this Note will be made in the Specified Currency. The Holder of this Note may elect to receive payment of the principal of and premium, if any, and/or interest on this Note in the Specified Currency specified on the face hereof by submitting a written request for such payment to the Trustee at its principal corporate trust office in Minneapolis, Minnesota on or prior to the applicable Record Date or at least fifteen calendar days prior to the Maturity, as the case may be. Such written request may be mailed or hand delivered or sent by cable, telex or other form of facsimile transmission. The Holder of this Note may elect to receive payment in the applicable Specified Currency for all such principal, premium, if any, and interest payments and need not file a separate election for each payment. Such election will remain in effect until revoked by written notice to the Trustee, but written notice of any such revocation must be received by the Trustee on or prior to the applicable Record Date or at least fifteen calendar days prior to the Maturity, as the case may be. If the Holder of this Note shall have duly made an election to receive payments of principal, premium, if any, or interest in the Specified Currency specified on the face hereof and the applicable Specified Currency is not available due to the imposition of exchange controls or other circumstances beyond the control of the Corporation, the Corporation shall be entitled to satisfy its obligations to the Holder hereof by making such payment in United States dollars on the basis of the Market Exchange Rate on the second Business Day prior to such payment or, if such Market Exchange Rate is not then available, on the basis of the most recently available Market Exchange Rate or as 7 8 otherwise provided herein. The "Market Exchange Rate" for a Specified Currency other than United States dollars means the noon dollar buying rate in The City of New York for cable transfer for such Specified Currency as certified for customs purposes by (or if not so certified, as otherwise determined by) the Federal Reserve Bank of New York. Any payment made under such circumstances in United States dollars where the required payment is in a Specified Currency other than United States dollars will not constitute an Event of Default under the Senior Indenture with respect to this Note. If the Holder of this Note shall have duly made an election to receive payments of principal, premium, if any, or interest hereon in the Specified Currency specified on the face hereof and such Specified Currency is European Currency Units ("ECUs") or another currency unit, and such currency unit is unavailable due to the imposition of exchange controls or other circumstances beyond the Corporation's control, then the Corporation shall be entitled, but not required, to make any payments in respect of this Note in United States dollars until such currency unit is again available. The amount of each payment in United States dollars shall be computed on the basis of the equivalent of the currency unit in United States dollars, which shall be determined by the Exchange Rate Agent on the following basis. The component currencies of the currency unit for this purpose (collectively, the "Component Currencies" and each, a "Component Currency") shall be the currency amounts that were components of the currency unit as of the last day on which the currency unit was used. The equivalent of the currency unit in United States dollars shall be calculated by aggregating the United States dollar equivalents of the Component Currencies. The United States dollar equivalent of each of the Component Currencies shall be determined by the Exchange Rate Agent on the basis of the most recently available Market Exchange Rate for each such Component Currency. If the official unit of any Component Currency is altered by way of combination or subdivision, the number of units of the currency as a Component Currency shall be divided or multiplied in the same proportion. If two or more Component Currencies are consolidated into a single currency, the amounts of those currencies as Component Currencies shall be replaced by an amount in such single currency equal to the sum of the amounts of the consolidated Component Currencies expressed in such single currency. If any Component Currency is divided into two or more currencies, the amount of the original Component Currency shall be replaced by the amounts of such two or more currencies, the 8 9 sum of which shall be equal to the amount of the original Component Currency. All determinations referred to above made by the Exchange Rate Agent shall be at its sole discretion and shall, in the absence of manifest error, be conclusive for all purposes and binding on the Holder hereof. Except as otherwise provided in the Senior Indenture and as set forth below, the Notes will be represented by one or more global securities, registered in the name of the Depositary or its nominee and ownership of the Notes shall be maintained in book-entry form by the Depositary for the accounts of participating organizations of the Depositary. This Note is exchangeable for definitive Notes in registered form to persons other than the Depositary or its nominee only if (a) the Depositary notifies the Corporation in writing that it is no longer willing or able to continue as a depositary for the Notes or if the Depositary ceases to be a clearing agency registered under the Securities Exchange Act of 1934, as amended, and a successor depositary is not appointed by the Corporation within ninety days after the effective date of the Depositary's ceasing to act as depositary for the Notes, (b) the Corporation, at its option, notifies the Trustee in writing that it elects to cause the issuance of Notes in definitive form, or (c) any event shall have happened and be continuing which, after notice or lapse of time, or both, would constitute an Event of Default with respect to the Notes. In the event of such occurrences, upon the surrender by the Depositary or a successor depositary of this Note the Corporation will execute, and the Trustee will, upon the execution of the then standard form of the Trustee's agreement for certificated securities and upon receipt of instructions in writing from the Corporation, authenticate and deliver securities of like tenor and terms in definitive form to each person that the Depositary or a successor depositary identifies as the beneficial owner of an interest in this Note in an aggregate principal amount equal to the principal amount of Notes represented by this Note then outstanding in exchange for this Note. Any such certificated security will be issued in fully registered form, without coupons, in an Authorized Denomination specified on the face hereof. Such certificated security may not subsequently be exchanged by a Holder for Notes in denominations of less than the minimum Authorized Denomination specified on the face hereof. This Note is not subject to any sinking fund or to the defeasance or covenant defeasance provisions of the Senior 9 10 Indenture and, unless otherwise provided above in accordance with the provisions of the following paragraphs, is not redeemable or repayable prior to the Stated Maturity Date. If so provided above, this Note may be redeemed by the Corporation on any date on and after the Initial Redemption Date, if any, specified above. If no Initial Redemption Date is set forth above, this Note may not be redeemed prior to the Stated Maturity Date. On and after the Initial Redemption Date, if any, this Note may be redeemed at any time in whole or from time to time in part in increments of $1,000 (or, if the Specified Currency indicated on the face hereof is other than United States dollars, the minimum Authorized Denomination specified on the face hereof) at the option of the Corporation at the applicable Redemption Price (as defined below), together with unpaid interest, if any, accrued hereon at the applicable rate payable to the date of redemption (each such date, a "Redemption Date"), on written notice given not more than 60 nor less than 30 calendar days prior to the Redemption Date. In the event of redemption of this Note in part only, a new Note for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon the surrender hereof. Whenever less than all the Notes at any time outstanding are to be redeemed, the terms of the Notes to be so redeemed shall be selected by the Corporation. In the event of redemption of this Note in part only, a new Note for the unredeemed portion hereof shall be issued in the name of the Holder hereof upon surrender hereof. Unless otherwise specified above, the "Redemption Price" shall initially be the Initial Redemption Percentage, specified above, of the principal amount of this Note to be redeemed and, if greater than 100%, shall decline at each anniversary of the Initial Redemption Date by the Annual Redemption Percentage Reduction, if any, specified above, of the principal amount to be redeemed until the Redemption Price is 100% of such principal amount. This Note may be subject to repayment at the option of the Holder on the Optional Repayment Date(s), if any, indicated above. If no Optional Repayment Date(s) are set forth above, this Note is not subject to repayment at the option of the Holder hereof prior to the Stated Maturity Date. On any Optional Repayment Date, this Note shall be repayable in whole or in part in increments of $1,000 (or, if the Specified Currency indicated on the face hereof is other than United States dollars, in the minimum Authorized Denomination specified on the face hereof) at the option of the Holder hereof at a repayment price equal to the 10 11 sum of (i) 100% of the unpaid principal amount to be repaid plus (ii) accrued interest, if any, hereon at the applicable rate payable to the relevant Optional Repayment Date. For this Note to be repaid in whole or in part at the option of the Holder hereof, this Note must be received, with the form entitled "Option to Elect Repayment" below duly completed, by one of the Paying Agents at its office, or such address which the Corporation shall from time to time notify the Holders of the Notes, not more than 60 nor less than 30 days prior to the relevant Optional Repayment Date. Exercise of such repayment option by the Holder hereof shall be irrevocable. In the event of repayment of this Note in part only, a new Note for the unrepaid portion hereof shall be issued in the name of the Holder hereof upon the surrender hereof. While this Note is held by or on behalf of the Depositary, and registered in the name of the Depositary or the Depositary's nominee, the option for repayment may be exercised by the applicable participant that has an account with the Depositary, on behalf of the beneficial owners of this Note, by delivering a written notice substantially similar to the above mentioned form to one of the Paying Agents at its office (or such other address of which the Corporation shall from time to time notify the Holders), not more than 60 nor less than 30 days prior to the date of repayment. Notices of elections from participants on behalf of beneficial owners of this Note to exercise their option to have the interests of such beneficial owners in this Note repaid must be received by one of the Paying Agents not later than 5:00 P.M., New York City time, on the last day for giving such notice. In order to ensure that a notice is received by one of the Paying Agents on a particular day, the beneficial owner of this Note must so direct the applicable participant before such participant's deadline for accepting instructions for that day. Different firms may have different deadlines for accepting instructions from their customers. Accordingly, beneficial owners of this Note should consult the participants through which they own their interest herein for the respective deadlines for such participants. All notices shall be executed by a duly authorized officer of such participant (with signature guaranteed) and shall be irrevocable. In addition, beneficial owners of this Note shall effect delivery at the time such notices of election are given to the Depositary by causing the applicable participant to transfer such beneficial owner's interest in this Note, on the Depositary's records, to the Trustee. 11 12 Interest payments on this Note shall include interest accrued from and including the Original Issue Date indicated above, or the most recent date to which interest has been paid or duly provided for, to but excluding the related Interest Payment Date or Maturity, as the case may be. Interest payments for this Note shall be computed and paid on the basis of a 360-day year of twelve 30-day months if the Day Count Convention specified above is "30/360" for the period specified thereunder, on the basis of the actual number of days in the related month and a 360-day year if the Day Count Convention specified above is "Actual/360" for the period specified thereunder or on the basis of the actual number of days in the related year and month if the Day Count Convention specified above is "Actual/Actual" for the period specified thereunder. As used herein, "Business Day" means, unless otherwise specified above, any day, other than a Saturday or Sunday, that is neither a legal holiday nor a day on which banking institutions are authorized or required by law, regulation or executive order to close in The City of New York or Boston, Massachusetts; provided, however, that, if the Holder hereof shall have duly made an election to receive payments of principal of and premium, if any, and/or interest on this Note in the Specified Currency specified on the face hereof, such day is also not a day on which banking institutions are authorized or required by law, regulation or executive order to close in the principal financial center of the country of such Specified Currency (or, in the case of ECUs, is not a day designated as an ECU Non-Settlement Day by the ECU Banking Association or otherwise generally regarded in the ECU interbank market as a day on which payments in ECUs shall not be made). Any provision contained herein with respect to the calculation of the rate of interest applicable to this Note, its Interest Payment Dates or any other matter relating hereto may be modified as specified in an Addendum relating hereto if so specified above. If an Event of Default (as defined in the Senior Indenture) with respect to the Notes shall occur and be continuing, the principal of all the Notes may be declared due and payable in the manner and with the effect provided in the Senior Indenture. If this Note is an Original Issue Discount Note, the amount payable to the Holder of this Note in the event of redemption, repayment or acceleration of maturity will be equal to (i) the Amortized Face Amount (as defined below) as of the date of such 12 13 event, plus (ii) with respect to any redemption of an Original Issue Discount Note, the Initial Redemption Percentage specified on the face hereof (as adjusted by the Annual Redemption Percentage Reduction, if any) minus 100% multiplied by the Issue Price specified on the face hereof, net of any portion of such Issue Price which has been paid prior to the date of redemption, or the portion of the Issue Price (or the net amount) proportionate to the portion of the unpaid principal amount to be redeemed, plus (iii) any accrued interest to the date of such event the payment of which would constitute qualified stated interest payments within the meaning of Treasury Regulation 1.1273-1(c) under the Internal Revenue Code of 1986, as amended (the "Code"). The "Amortized Face Amount" shall mean an amount equal to (i) the Issue Price hereof plus (ii) the aggregate portions of the original issue discount (the excess of the amounts considered as part of the "stated redemption price at maturity" of such Original Issue Discount Note within the meaning of Section 1273(a)(2) of the Code, whether denominated as principal or interest, over the Issue Price) which shall theretofore have accrued pursuant to Section 1272 of the Code (without regard to Section 1272(a)(7) of the Code) from the date of issue of such Original Issue Discount Note to the date of determination, minus (iii) any amount considered as part of the "stated redemption price at maturity" of such Original Issue Discount Note which has been paid from the date of issue to the date of determination. The Senior Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Corporation and the rights of the Holders of the Securities of each series to be affected under the Senior Indenture at any time by the Corporation and the Trustee with the consent of the Holders of 66 2/3% in aggregate principal amount of the Securities at the time Outstanding, as defined in the Senior Indenture, of each series affected thereby. The Senior Indenture also contains provisions permitting the Holders of specified percentages in aggregate principal amount of the Outstanding Securities of each series at the time, on behalf of the Holders of all Securities of each series, to waive compliance with certain provisions of the Senior Indenture and certain past defaults under the Senior Indenture and their consequences. Any such consent or waiver by the Holder of this Note shall be conclusive and binding upon such Holder and upon all future Holders of this Note and of any Note issued upon the registration of transfer hereof or in exchange herefor or in lieu hereof whether or not notation of such consent or waiver is made upon this Note. 13 14 No reference herein to the Senior Indenture and no provision of this Note or of the Senior Indenture shall alter or impair the obligation of the Corporation, which is absolute and unconditional, to pay the principal of and interest on this Note at the time, place and rate, and in the coin or currency, herein prescribed. As provided in the Senior Indenture and subject to certain limitations therein set forth, this registered Note may be presented for transfer (duly endorsed or accompanied by a written instrument of transfer, if so required by the Corporation or the Security Registrar) or exchanged for other Notes of the same series at the office of BancBoston Trust Corporation of New York in The City of New York or the principal office of The First National Bank of Boston in The City of Boston. No service charge shall be made for any such registration of transfer or exchange, but the Corporation may require payment of a sum sufficient to cover any tax or other governmental charge payable in connection therewith.
