STATE STREET CORPORATION

4.956% JUNIOR SUBORDINATED DEBENTURE DUE 2018

STATE STREET CORPORATION, a corporation organized and existing under the laws of Massachusetts (hereinafter called the “Company”, which term includes any successor corporation under the Original Indenture hereinafter referred to), for value received, hereby promises to pay to Cede & Co., or registered assigns the principal sum of                      Dollars on March 15, 2018 (such date is hereinafter referred to as the “Stated Maturity Date”). The Company further promises to pay interest on said principal sum from September 15, 2010, or from the most recent interest payment date (each such date, an “Interest Payment Date”) on which interest has been paid or duly provided for (subject to deferral as set forth herein), semi-annually in arrears on March 15 and September 15 of each year, commencing March 15, 2011, at the rate of 6.001% per annum from and including September 15, 2010 to but not including February 11, 2011 and at the rate of 4.956% per annum from and including February 11, 2011 until the principal hereof is paid or duly provided for or made available for payment. The amount of interest payable for any period shall be calculated on the basis of a 360-day year consisting of twelve 30-day months. In the event that any date on which interest is payable on this Junior Subordinated Debenture is not a Business Day, then a payment of the interest payable on such date will be made on the next succeeding day that is a Business Day (and without any interest or other payment in respect of any such delay), in each case with the same force and effect as if made on the date the payment was originally payable. A “Business Day” shall mean any day other than a Saturday, Sunday, or any other day on which banking institutions and trust companies in New York, New York, Boston, Massachusetts or Wilmington, Delaware, are permitted or required by any applicable law to close. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture (as hereinafter defined), be paid to the Person in whose name this Junior Subordinated Debenture (or one or more Predecessor Securities) is registered at the close of business on the

6

Regular Record Date for such interest installment, which shall be the date that is the last day of the month immediately preceding the month in which such Interest Payment Date falls (whether or not a Business Day). Any such interest installment not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such Regular Record Date and may either be paid to the Person in whose name this Junior Subordinated Debenture (or one or more Predecessor Securities) is registered at the close of business on a Special Record Date for the payment of such Defaulted Interest to be fixed by the Trustee, notice whereof shall be given to Holders of Junior Subordinated Debentures not less than 10 days prior to such Special Record Date, or be paid at any time in any other lawful manner not inconsistent with the requirements of any securities exchange on which the Junior Subordinated Debentures may be listed, and upon such notice as may be required by such exchange, all as more fully provided in said Indenture.

If the principal amount hereof or any portion of such principal amount is not paid when due (whether upon acceleration, upon the date set for payment of the Redemption Price or upon the Stated Maturity Date) or if interest due hereon (or any portion of such interest), is not paid when due, then in each such case the overdue amount shall, to the extent permitted by law, bear interest at the rate then borne by this Junior Subordinated Debenture for the applicable Interest Period, compounded at the end of such Interest Period, which interest shall accrue from the date such overdue amount was originally due to the date payment of such amount, including interest thereon, has been made or duly provided for. All such interest shall be payable as set forth in the Indenture.

The Company shall have the right at any time during the term of this Junior Subordinated Debenture to defer payment of interest on this Junior Subordinated Debenture, at any time or from time to time, for up to 10 consecutive semi-annual Interest Periods (or the equivalent thereof, if the Interest Periods are not then semi-annual) with respect to each deferral period (each, an “Extension Period”), during which Extension Periods the Company shall have the right to make partial payments of interest on any Interest Payment Date, and at the end of which the Company shall pay all interest then accrued and unpaid (together with Additional Interest thereon to the extent permitted by applicable law); provided that no Extension Period shall extend beyond the Stated Maturity Date of the principal of this Junior Subordinated Debenture; provided, further, that during any such Extension Period, the Company shall not, and shall not permit any Subsidiary of the Company to, (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire or make a liquidation payment with respect to, any shares of the Company’s capital stock, (ii) make any payment of principal of or interest or premium, if any, on or repay, repurchase or redeem any debt security of the Company that ranks or make any payments under any guarantee that ranks, upon liquidation, pari passu in all respects with the Junior Subordinated Debenture (including this Junior Subordinated Debenture, “Parity Securities”) or any debt security of the Company that ranks junior to the Junior Subordinated Debenture or (iii) make any payments with respect to any guarantee by the Company of the debt securities of any Subsidiary of the Company that by their terms ranks equal or junior in interest to the Guarantee related to the APEX (other than (a) any repurchase, redemption or other acquisition of shares of the Company’s capital stock in connection with (1) any employment contract, benefit plan or other similar arrangement with or for the benefit of any one or more employees, officers, directors, consultants or independent contractors, (2) the satisfaction of the Company’s obligations pursuant to any contract entered into in the ordinary course prior to the beginning of the Extension Period, (3) a dividend reinvestment or stockholder purchase plan, or (4) the issuance of the Company’s capital stock, or securities convertible into or exercisable for such capital stock, as consideration in an acquisition transaction entered into prior to the applicable Extension Period; (b) any exchange, redemption or conversion of any class or series of the Company’s capital stock, or the capital stock of one of its subsidiaries, for any other class or

7

series of the Company’s capital stock, or any class or series of the Company’s indebtedness for any class or series of its capital stock; (c) any purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the securities being converted or exchanged; (d) any declaration of a dividend in connection with any rights plan, or the issuance of rights, stock or other property under any rights plan, or the redemption or repurchase of rights pursuant thereto; (e) payments under any Guarantee Agreement; (f) any payment of current or deferred interest on Parity Securities that is made pro rata to the amounts due on such Parity Securities (including the Junior Subordinated Debentures) and any payments of principal of or deferred interest on Parity Securities that, if not made, would cause the Company to breach the terms of the instrument governing such Parity Securities; or (g) any dividend in the form of stock, warrants, options or other rights where the dividend stock or stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks equally with or junior to such stock). Prior to the termination of any such Extension Period, the Company may further extend the interest payment period, provided that no Extension Period shall exceed 10 consecutive semi-annual Interest Periods or extend beyond the Stated Maturity Date of the principal of this Junior Subordinated Debenture. Upon the termination of any such Extension Period and upon the payment of all accrued and unpaid interest then due, the Company may elect to begin a new Extension Period, subject to the above requirements. Subject to the last sentence of this paragraph, no interest shall be due and payable during an Extension Period except at the end thereof. The Company shall give the Trustee and the Paying Agent notice of its election to begin or extend any Extension Period at least 10 Business Days prior to the date on which interest on the Junior Subordinated Debentures would be payable but for the election to begin or extend such Extension Period. The Trustee or its designee shall give notice of the Company’s election to begin or extend any Extension Period to the Holders of the Junior Subordinated Debentures and to the Administrative Trustees.

Payment of the principal of (and premium, if any) and interest on this Junior Subordinated Debenture will be made to the Depositary.

The indebtedness evidenced by this Junior Subordinated Debenture is, to the extent provided in the Indenture, subordinate and junior in right of payment and upon liquidation to the prior payment in full of all Senior Indebtedness, and this Junior Subordinated Debenture is issued subject to the provisions of the Indenture with respect thereto. Each Holder of this Junior Subordinated Debenture, by accepting the same, (a) agrees to and shall be bound by such provisions, (b) authorizes and directs the Trustee on his behalf to take such actions as may be necessary or appropriate to effectuate the subordination so provided and (c) appoints the Trustee his attorney-in-fact for any and all such purposes. Each Holder hereof, by his acceptance hereof, waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions.

Reference is hereby made to the further provisions of this Junior Subordinated Debenture set forth on the reverse hereof, which further provisions shall for all purposes have the same effect as if set forth at this place.

Unless the certificate of authentication hereon has been executed by the Trustee referred to on the reverse hereof by manual signature, this Junior Subordinated Debenture shall not be entitled to any benefit under the Indenture or be valid or obligatory for any purpose.

IN WITNESS WHEREOF, the Company has caused this instrument to be duly executed under its corporate seal.
