GLOBAL SUBORDINATED BANK NOTE

(Floating Rate)

The Northern Trust Company, an Illinois banking corporation (the “Bank”), for value received, hereby promises to pay to Cede & Co., or registered assigns, the principal amount specified on the face hereof in United States Dollars on the Maturity Date specified above and to pay interest thereon from the Original Issue Date specified above or from the most recent interest payment date (or, if the Interest Reset Period specified above is daily or weekly, from, and including, the day following the most recent Regular Record Date) to which interest on this Subordinated Note (or any predecessor Subordinated Note) has been paid or made available for payment (each, an “Interest Payment Date”), on the Interest Payment Dates specified above and at maturity or upon earlier redemption, if applicable, commencing on the first Interest Payment Date next succeeding the Original Issue Date (or, if the Original Issue Date is between a Regular Record Date and the Interest Payment Date immediately following such Regular Record Date, on the second Interest Payment Date following the Original Issue Date), at a rate per annum equal to the Initial Base Rate specified above, as adjusted by the addition or subtraction of the Spread, if any, specified above and/or by the multiplication by the Spread Multiplier, if any, specified above, until the first Interest Reset Date following the Original Issue Date and, on and after such Interest Reset Date, at the rate determined in accordance with the provisions set forth herein, until the principal hereof is paid or made available for payment, and (to the extent that the payment of such interest shall be legally enforceable) at the last rate in effect prior to any payment default on any overdue principal and premium, if any, and on any overdue installment of interest. The interest so payable, and punctually paid or made available for payment, on any Interest Payment Date will be paid to the person in whose name this Subordinated Note (or any predecessor Subordinated Note) is registered at the close of business on the Regular Record Date for such interest, which shall be the 15th calendar day (whether or not a Business Day (as defined below)) before such Interest Payment Date (unless otherwise

specified on the face hereof); provided, however, that interest payable at maturity or upon earlier redemption, if applicable, will be payable to the person to whom principal shall be payable.

Payment of principal of, and premium, if any, and interest on, this Subordinated Note will be made in such coin or currency of the United States of America as at the time of payment is legal tender for payment of public and private debts. The Bank will at all times appoint and maintain a paying agent (the “Paying Agent”) authorized by the Bank to pay the principal of, and premium, if any, and interest on, this Subordinated Note on behalf of the Bank and having an office or agency (the “Paying Agent Office”) in The City of New York or the City of Chicago, Illinois (the “Place of Payment”), where this Subordinated Note may be presented or surrendered for payment and where notices, designations or requests in respect of payments with respect to this Subordinated Note may be served. The Bank has initially appointed itself as such Paying Agent, with the Paying Agent Office currently located at 50 South LaSalle Street (Level BB-A), Chicago, Illinois 60675, Attention: Securities Services.

THIS SUBORDINATED NOTE IS A DIRECT, UNCONDITIONAL AND UNSECURED GENERAL OBLIGATION OF THE BANK. THIS SUBORDINATED NOTE IS NOT INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION, IS NOT A DEPOSIT OF, OR GUARANTEED BY, THE BANK, AND IS SUBJECT TO INVESTMENT RISKS, INCLUDING POSSIBLE LOSS OF THE PRINCIPAL AMOUNT INVESTED. THIS SUBORDINATED NOTE IS SUBORDINATE TO THE CLAIMS OF DEPOSITORS AND GENERAL CREDITORS OF THE BANK.

Payment of the principal of, and premium, if any, and interest on, this Subordinated Note due at maturity or upon earlier redemption, if applicable, will be made in immediately available funds upon presentation and surrender of this Subordinated Note to the Paying Agent at the Paying Agent Office in the Place of Payment; provided that this Subordinated Note is presented to the Paying Agent in time for the Paying Agent to make such payment in accordance with its normal procedures. Payments of interest on this Subordinated Note (other than at maturity or upon earlier redemption) will be made by wire transfer to such account as has been appropriately designated to the Paying Agent by the person entitled to such payments.

This Subordinated Note is one of a duly authorized issue of Subordinated Bank Notes due from five to fifteen years from date of issue of the Bank (herein called the “Subordinated Notes”).

Unless otherwise indicated on the face hereof, if the rate of interest on this Subordinated Note resets daily, weekly or monthly, the Interest Payment Date for this Subordinated Note will be the third Wednesday of each month or the third Wednesday of March, June, September and December of each year; if the rate of interest on this Subordinated Note resets quarterly, the Interest Payment Date for this Subordinated Note will be the third Wednesday of March, June, September and December of each year; if the rate of interest on this

Subordinated Note resets semi-annually, the Interest Payment Date for this Subordinated Note will be the third Wednesday of each of two months of each year specified on the face hereof that are six months apart; and if the rate of interest on this Subordinated Note resets annually, the Interest Payment Date for this Subordinated Note will be the third Wednesday of the month specified on the face hereof. If any Interest Payment Date (unless it is also the Maturity Date) for this Subordinated Note falls on a day that is not a Business Day, such Interest Payment Date will be postponed to the next succeeding Business Day; provided, however, that, if the Interest Rate Basis specified on the face hereof is LIBOR and such next succeeding Business Day is in the next succeeding calendar month, such Interest Payment Date (unless it is also the Maturity Date) will be the immediately preceding Business Day. If any Maturity Date or date of earlier redemption or repayment of this Subordinated Note falls on a day that is not a Business Day, the related payment of interest shall be made on the next succeeding Business Day with the same force and effect as if made on the date such payment were due, and no interest shall accrue on the amount so payable for the period from and after such Maturity Date or date of earlier redemption or repayment. “Business Day” means any day other than a Saturday, Sunday or a day on which banking institutions in The City of New York or the City of Chicago, Illinois generally are authorized or obligated by law or executive order to close, and with respect to Subordinated Notes with respect to which the Interest Rate Basis specified on the face hereof is LIBOR, any day on which dealings in U.S. dollars are transacted in the London interbank market (a “London Business Day”).

The indebtedness of the Bank evidenced by this Subordinated Note, including principal and interest, is unsecured and subordinate and junior in right of payment to the Bank’s obligations to its depositors, its obligations under bankers’ acceptances and letters of credit, and its obligations to its other creditors (including any obligations to any Federal Reserve Bank and the Federal Deposit Insurance Corporation), whether now outstanding or hereafter incurred, other than any obligations which rank on a parity with, or junior to, the Subordinated Notes. In the event of any insolvency proceeding, receivership, conservatorship, reorganization, readjustment of debt, marshalling of assets and liabilities or similar proceedings or any liquidation or winding-up of the Bank, whether voluntary or involuntary, all such obligations (except obligations which rank on a parity with, or junior to, the Subordinated Notes) shall be entitled to be paid in full before any payment shall be made on account of the principal of, or interest on, the Subordinated Notes. In the event of any such proceeding, after payment in full of all sums owing with respect to such prior obligations, the holders of the Subordinated Notes, together with the holders of any obligations of the Bank ranking on a parity with the Subordinated Notes, shall be entitled to be paid, from the remaining assets of the Bank, the unpaid principal of, and the unpaid interest on, the Subordinated Notes or such other obligations before any payment or other distribution, whether in cash, property, or otherwise, shall be made on account of any capital stock or any obligations of the Bank ranking junior to the Subordinated Notes.

The Subordinated Notes shall rank on a parity with (i) the $700,000,000 aggregate principal amount of subordinated indebtedness represented by $200,000,000 aggregate principal amount of 4.60% Subordinated Notes due 2013, $200,000,000 aggregate principal amount of 5.85% Subordinated Notes due 2017, and $300,000,000 aggregate principal amount of 6.50%

Subordinated Notes due 2018, (ii) the £150,000,000 aggregate principal amount of 5.375% Subordinated Notes due 2015 that were issued in 2005, (iii) the $200,000,000 aggregate principal amount of floating rate subordinated notes due 2017 issued in 2007 to Northern Trust Corporation, (iv) the $750,000,000 aggregate principal amount of fixed rate senior notes due 2016 issued in 2011 to the Northern Trust Corporation, and (v) such other obligations which may be issued by the Bank which are specifically designated as ranking on a parity with the Subordinated Notes by express provision in the instruments creating or evidencing such obligations.

This Subordinated Note will not be subject to any sinking fund. If so provided on the face of this Subordinated Note and subject to the approval of the Federal Reserve Bank of Chicago, this Subordinated Note may be redeemed by the Bank on and after the Initial Redemption Date, if any, specified on the face hereof. If no Initial Redemption Date is specified on the face hereof, this Subordinated Note may not be redeemed prior to the Maturity Date. On and after the Initial Redemption Date, if any, and subject to the approval of the Federal Reserve Bank of Chicago, this Subordinated Note may be redeemed at any time either in whole or in part from time to time in increments of $1,000 (provided that any remaining principal amount hereof shall be at least $250,000) at the option of the Bank at the applicable Redemption Price (as defined below), together with accrued and unpaid interest hereon at the applicable rate borne by this Subordinated Note 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 by the Bank to the registered holder hereof. Whenever less than all the Subordinated Notes at any time outstanding are to be redeemed, the terms of the Subordinated Notes to be so redeemed shall be selected by the Bank. If less than all the Subordinated Notes with identical terms at any time outstanding are to be redeemed, the Subordinated Notes to be so redeemed shall be selected by the Paying Agent by lot or in any usual manner approved by it. In the event of redemption of this Subordinated Note in part only, a new Subordinated Note for the unredeemed portion hereof shall be issued in the name of the holder hereof upon the surrender hereof.

The “Redemption Price” shall initially be the Initial Redemption Percentage specified on the face hereof of the principal amount of this Subordinated Note to be redeemed and shall decline at each anniversary of the Initial Redemption Date specified on the face hereof by the Annual Redemption Percentage Reduction, if any, specified on the face hereof, of the principal amount to be redeemed until the Redemption Price is 100% of such principal amount.

This Subordinated Note will not be repayable at the option of the holder hereof prior to maturity.

The rate of interest on this Subordinated Note will be reset daily, weekly, monthly, quarterly, semi-annually or annually (each such period, an “Interest Reset Period” for this Subordinated Note, and the first calendar day of an Interest Reset Period, an “Interest Reset Date”), as specified on the face hereof. Unless otherwise indicated on the face hereof, if this Subordinated Note resets daily, the Interest Reset Date will be each Business Day; if this

Subordinated Note resets weekly and the Interest Rate Basis is not the Treasury Rate, the Interest Reset Date will be the Wednesday of each week; if this Subordinated Note resets weekly and the Interest Rate Basis is the Treasury Rate, the Interest Reset Date will be the Tuesday of each week (except as provided below); if this Subordinated Note resets monthly, the Interest Reset Date will be the third Wednesday of each month; if this Subordinated Note resets quarterly, the Interest Reset Date will be the third Wednesday of March, June, September and December; if this Subordinated Note resets semi-annually, the Interest Reset Date will be the third Wednesday of each of two months of each year which are six months apart, as specified on the face hereof; and if this Subordinated Note resets annually, the Interest Reset Date will be the third Wednesday of one month of each year, as specified on the face hereof; provided, however, that the base rate in effect from the Original Issue Date to the first Interest Reset Date will be the Initial Base Rate specified on the face hereof. If any Interest Reset Date with respect to this Subordinated Note would otherwise be a day that is not a Business Day, such Interest Reset Date will be the next succeeding Business Day, except that in the case that the Interest Rate Basis specified on the face hereof is LIBOR, if such Business Day is in the next succeeding calendar month, such Interest Reset Date will be the immediately preceding Business Day.

All calculations relating to this Subordinated Note will be made by the “Calculation Agent.” The Bank will serve as Calculation Agent for this Subordinated Note as of its Original Issue Date, unless otherwise specified on the face hereof. The Bank may appoint a different institution to serve as Calculation Agent from time to time after the Original Issue Date of this Subordinated Note without the consent of the holder and without notice.

The Calculation Agent will determine the interest rate that takes effect on an Interest Reset Date by reference to the Interest Determination Date. Unless otherwise specified on the face hereof, (i) if the Interest Rate Basis is not LIBOR or the Treasury Rate, the Interest Determination Date will be the second Business Day before the Interest Reset Date; (ii) if the Interest Rate Basis is LIBOR, the Interest Determination Date will be the second London Business Day (as defined below) preceding the Interest Reset Date; and (iii) if the Interest Rate Basis is the Treasury Rate, the Interest Determination Date will be the day of the week in which the Interest Reset Date falls on which treasury bills — i.e., direct obligations of the U.S. government — would normally be auctioned. Treasury bills are usually sold at auction on the Monday of each week, unless that day is a legal holiday, in which case the auction is usually held on the following Tuesday but may be held on the preceding Friday. If as the result of a legal holiday an auction is held on the preceding Friday, that Friday will be the Treasury Interest Determination Date relating to the Interest Reset Date occurring in the next succeeding week. If the auction is held on a day that would otherwise be an Interest Reset Date, then the Interest Reset Date will instead be the first Business Day following the auction date.

Unless the Interest Rate is LIBOR, the Calculation Agent will calculate the interest rate that takes effect on a particular Interest Reset Date no later than the corresponding Interest Calculation Date. The Interest Calculation Date will be the earlier of (i) the tenth calendar day after the Interest Determination Date or, if that tenth calendar day is not a Business Day, the next succeeding Business Day, and (ii) the Business Day immediately preceding the

Interest Payment Date or the Maturity Date on which the next payment of interest will be due. The Calculation Agent need not wait until the relevant Interest Calculation Date to determine the interest rate if the rate information it needs to make the determination is available from the relevant sources sooner.

For each Interest Reset Period, the Calculation Agent will calculate the amount of accrued interest by multiplying the face amount of this Subordinated Note by an accrued interest factor for the Interest Reset Period. This factor will equal the sum of the interest factors calculated for each day during the Interest Reset Period. The interest factor for each day will be expressed as a decimal and will be calculated by dividing the interest rate (also expressed as a decimal) applicable to that day (i) by 360, if the Interest Rate Basis is the Commercial Paper Rate, the Prime Rate, LIBOR, the CD Rate or the Federal Funds Rate, or (ii) by the actual number of days in the year, if the Interest Rate Basis is the Treasury Rate or the CMT Rate.

Upon the request of the holder of this Subordinated Note, the Calculation Agent will provide such holder with the interest rate then in effect for this Subordinated Note and, if determined, the interest rate that will become effective on the next Interest Reset Date. The Calculation Agent’s determination of any interest rate, and its calculation of the amount of interest for any Interest Reset Period, will be final and binding in the absence of manifest error.

All percentages resulting from any calculation relating to this Subordinated Note will be rounded upward or downward, as appropriate, to the next higher or lower one hundred-thousandth of a percentage point. For example, 9.876541% (or .09876541) would be rounded down to 9.87654% (or .0987654) and 9.876545% (or .09876545) would be rounded up to 9.87655% (or .0987655). All amounts used in or resulting from any calculation relating to this Subordinated Note will be rounded upward or downward, as appropriate, to the nearest cent, with one-half cent or more being rounded upward.

In determining the Base Rate that applies this Subordinated Note during a particular Interest Reset Period, the Calculation Agent may obtain rate quotes from various banks or dealers active in the relevant market, as described in the following subsections. Those reference banks and dealers may include the Calculation Agent itself, including the Bank, and its affiliates.

Except as otherwise provided herein, the rate of interest on this Subordinated Note for each Interest Reset Date will be the rate determined in accordance with the provisions set forth under the applicable heading below corresponding to the Interest Rate Basis specified on the face hereof. Notwithstanding the foregoing, the interest rate hereon shall not be greater than the Maximum Interest Rate, if any, specified on the face hereof and shall not be lower than the Minimum Interest Rate, if any, specified on the face hereof. In addition, the interest rate hereon will in no event be greater than the maximum rate permitted by Illinois law, as the same may be modified by United States law of general application.

Commercial Paper Rate. If the Interest Rate Basis of this Subordinated Note is the Commercial Paper Rate, this Subordinated Note will bear interest at a Base Rate equal to the Commercial Paper Rate, as adjusted by the Spread or Spread Multiplier, if any, specified on the face hereof.

The Commercial Paper Rate will be the Money Market Yield (as defined below) of the rate, for the relevant Interest Determination Date, for commercial paper having the Index Maturity (as defined below) specified on the face of this Subordinated Note, as published in H.15(519) (as defined below) under the heading “Commercial Paper — Nonfinancial.” If the Commercial Paper Rate cannot be determined as described above, the following procedures will apply:

(i) If the rate described above does not appear in H.15(519) at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from that source at that time), then the Commercial Paper Rate will be the rate, for the relevant Interest Determination Date, for commercial paper having the Index Maturity specified on the face of this Subordinated Note, as published in H.15 Daily Update (as defined below) or another recognized electronic source used for displaying that rate, under the heading “Commercial Paper —Nonfinancial.”

(ii) If the rate described above does not appear in H.15(519), H.15 Daily Update or another recognized electronic source at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from one of those sources at that time), the Commercial Paper Rate will be the Money Market Yield of the arithmetic mean of the offered rates, as of 11:00 AM., New York City time, on the relevant Interest Determination Date, by three leading U.S. dollar commercial paper dealers in New York City selected by the Calculation Agent for U.S. dollar commercial paper that has the relevant Index Maturity and is placed for an industrial issuer whose bond rating is “AA”, or the equivalent, from a nationally recognized rating agency.

(iii) If fewer than three dealers selected by the Calculation Agent are quoting as described above, the Commercial Paper Rate for the new Interest Reset Period will be the rate in effect for the prior Interest Reset Period.

LIBOR. If the Interest Rate Basis of this Subordinated Note is LIBOR, this Subordinated Note will bear interest at a Base Rate equal to LIBOR, as adjusted by the Spread or Spread Multiplier, if any, specified on the face hereof. LIBOR will be the London interbank offered rate for deposits of U.S. dollars. LIBOR will be determined in the following manner

(i) LIBOR will be the offered rate appearing on the Reuters Screen LIBOR01 Page (as defined below) as of 11:00 A.M., London time, on the relevant LIBOR Interest Determination Date, for deposits of U.S. dollars having the relevant Index Maturity beginning on the relevant Interest Reset Date

(ii) If no rate appears on the Reuters Screen LIBOR01 Page, then LIBOR will be determined on the basis of the rates, at approximately 11:00 A.M., London time, on the relevant LIBOR Interest Determination Date, for deposits of U.S. dollars having the relevant Index Maturity, beginning on the relevant Interest Reset Date and in a Representative Amount (as defined below), are offered to prime banks in the London interbank market by four major banks in that market selected by the Calculation Agent. The Calculation Agent will request the principal London office of each of these banks to provide a quotation of its rate. If at least two quotations are provided, LIBOR for the relevant LIBOR Interest Determination Date will be the arithmetic mean of the quotations.

(iii) If fewer than two quotations are provided as described above, LIBOR for the relevant LIBOR Interest Determination Date will be the arithmetic mean of the rates for loans of U.S. dollars having the relevant Index Maturity, beginning on the relevant Interest Reset Date and in a Representative Amount to leading European banks quoted, at approximately 11:00 A.M., New York City time, on that LIBOR Interest Determination Date, by three major banks in New York City selected by the Calculation Agent.

(iv) If fewer than three banks selected by the Calculation Agent are quoting as described above, LIBOR for the new Interest Reset Period will be the rate in effect for the prior Interest Reset Period.

Treasury Rate. If the Interest Rate Basis of this Subordinated Note is the Treasury Rate, this Subordinated Note will bear interest at a Base Rate equal to the Treasury Rate, as adjusted by the Spread or Spread Multiplier, if any, specified on the face hereof.

The Treasury Rate will be the rate for the auction, on the relevant Treasury Interest Determination Date, of treasury bills having the Index Maturity specified in the on the face of this Subordinated Note, as that rate appears on Reuters Screen USAUCTION10 or USAUCTION11 under the heading “Investment Rate.” If the Treasury Rate cannot be determined in this manner, the following procedures will apply:

(i) If the rate described above does not appear on either page at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from that source at that time), the Treasury Rate will be the Bond Equivalent Yield (as defined below) of the rate, for the relevant Interest Determination Date, for the type of treasury bill described above, as published in H.15 Daily Update or another recognized electronic source used for displaying that rate, under the heading “U.S. Government Securities/Treasury Bills/Secondary Market.”

(ii) If the rate described in the prior paragraph does not appear in H.15 Daily Update or another recognized electronic source at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from one of those sources at that time), the Treasury Rate will be the Bond Equivalent Yield of the auction rate, for the relevant Treasury Interest Determination Date and for treasury bills of the kind described above, as announced by the U.S. Department of the Treasury.

(iii) If the auction rate described in the prior paragraph is not so announced by 3:00 P.M., New York City time, on the relevant Interest Calculation Date, or if no such auction is held for the relevant week, then the Treasury Rate will be the Bond Equivalent Yield of the rate, for the relevant Treasury Interest Determination Date and for treasury bills having a remaining maturity closest to the specified Index Maturity, as published in H.15(519) under the heading “U.S. Government Securities/Treasury Bills/Secondary Market.”

(iv) If the rate described in the prior paragraph does not appear in H.15(519) at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from one of those sources at that time), then the Treasury Rate will be the rate, for the relevant Treasury Interest Determination Date and for treasury bills having a remaining maturity closest to the specified Index Maturity, as published in H.15 Daily Update or another recognized electronic source used for displaying that rate, under the heading “U.S. Government Securities/Treasury Bills/Secondary Market.”

(v) If the rate described in the prior paragraph does not appear in H.15 Daily Update or another recognized electronic source at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from one of those sources at that time), the Treasury Rate will be the Bond Equivalent Yield of the arithmetic mean of the secondary market bid rates as of approximately 3:30 P.M., New York City time, on the relevant Treasury Interest Determination Date, of three primary U.S. government securities dealers in New York City selected by the Calculation Agent for the issue of treasury bills with a remaining maturity closest to the specified Index Maturity.

(vi) If fewer than three dealers selected by the Calculation Agent are quoting as described in the prior paragraph, the Treasury Rate in effect for the new Interest Reset Period will be the rate in effect for the prior Interest Reset Period.

CMT Rate. If the Interest Rate Basis of this Subordinated Note is the CMT Rate, this Subordinated Note will bear interest at a Base Rate equal to the CMT Rate, as adjusted by the Spread or Spread Multiplier, if any, specified on the face hereof.

The CMT Rate will be the rate displayed on the Designated CMT Reuters Screen Page (as defined below) under the heading “. . Treasury Constant Maturities . . . Federal Reserve Board Release H.15 . . . Mondays Approximately 3:45 P.M.,” under the column for the Designated CMT Index Maturity (as defined below), as follows: (a) if the Designated CMT Reuters Screen Page is Reuters Screen FRBCMT page, the rate for the relevant Interest Determination Date, or (b) if the Designated CMT Reuters Screen Page is Reuters Screen FEDCMT page, the weekly or monthly average, as specified on the face of this Subordinated Note, for the week that ends immediately before the week in which the relevant Interest

Determination Date falls, or for the month that ends immediately before the month in which the relevant Interest Determination Date falls, as applicable. If the CMT Rate cannot be determined in this manner, the following procedures will apply:

(i) If the applicable rate described above is not displayed on the relevant Designated CMT Reuters Screen Page at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from that source at that time), then the CMT Rate will be the applicable treasury constant maturity rate described above — that is, for the Designated CMT Index Maturity and for either the relevant Interest Determination Date or the weekly or monthly average, as applicable — as published in H.15(519).

(ii) If the applicable rate described above does not appear in H.15(519) at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from one of those sources at that time), then the CMT Rate will be the treasury constant maturity rate, or other U.S. treasury rate, for the Designated CMT Index Maturity and with reference to the relevant Interest Determination Date, that (a) is published by the Board of Governors of the Federal Reserve System, or the U.S. Department of the Treasury, and (b) is determined by the Calculation Agent to be comparable to the applicable rate formerly displayed on the Designated CMT Reuters Screen Page and published in H.15(519).

(iii) If the rate described in the prior paragraph does not appear at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from one of those sources at that time), then the CMT Rate will be the yield to maturity of the arithmetic mean of the offered rates, as of approximately 3:30 P.M., New York City time, on the relevant Interest Determination Date, of three primary U.S. government securities dealers in New York City selected by the Calculation Agent for the most recently issued treasury notes having an original maturity of approximately the Designated CMT Index Maturity and a remaining term to maturity of not less than the Designated CMT Index Maturity minus one year, and in a Representative Amount. In selecting these offered rates, the Calculation Agent will request quotations from five of these primary dealers and will disregard the highest quotation — or, if there is equality, one of the highest — and the lowest quotation — or, if there is equality, one of the lowest. Treasury notes are direct, non-callable, fixed rate obligations of the U.S. government.

(iv) If the Calculation Agent is unable to obtain three quotations of the kind described in the prior paragraph, the CMT rate will be the yield to maturity of the arithmetic mean of the offered rates, as of approximately 3:30 P.M., New York City time, on the relevant Interest Determination Date, of three primary U.S. government securities dealers in New York City selected by the Calculation Agent for treasury notes with an original maturity longer than the Designated CMT Index Maturity, with a remaining term to maturity closest to the Designated CMT Index Maturity and in a Representative Amount. In selecting these offered rates, the Calculation Agent will request quotations from five of these primary dealers and will disregard the highest quotation — or, if there

is equality, one of the highest — and the lowest quotation — or, if there is equality, one of the lowest. If two treasury notes with an original maturity longer than the Designated CMT Index Maturity have remaining terms to maturity that are equally close to the Designated CMT Index Maturity, the Calculation Agent will obtain quotations for the treasury note with the shorter remaining term to maturity.

(v) If fewer than five but more than two of these primary dealers are quoting as described in the prior paragraph, then the CMT Rate for the relevant Interest Determination Date will be based on the arithmetic mean of the offered rates so obtained, and neither the highest nor the lowest of those quotations will be disregarded.

(vi) If two or fewer primary dealers selected by the Calculation Agent are quoting as described above, the CMT Rate in effect for the new Interest Reset Period will be the rate in effect for the prior Interest Reset Period.

CD Rate. If the Interest Rate Basis of this Subordinated Note is the CD Rate, this Subordinated Note will bear interest at a Base Rate equal to the CD Rate, as adjusted by the Spread or Spread Multiplier, if any, specified on the face hereof.

The CD Rate will be the rate, on the relevant Interest Determination Date, for negotiable U.S. dollar certificates of deposit having the Index Maturity specified on the face of this Subordinated Note, as published in H.15(519) under the heading “CDs (Secondary Market).” If the CD Rate cannot be determined in this manner, the following procedures will apply:

(i) If the rate described above does not appear in H15(519) at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from that source at that time), then the CD Rate will be the rate, for the relevant Interest Determination Date, described above as published in H.15 Daily Update or another recognized electronic source used for displaying that rate, under the heading “CDs (Secondary Market).”

(ii) If the rate described above does not appear in H.15(519), H.15 Daily Update or another recognized electronic source at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from one of those sources at that time), the CD Rate will be the arithmetic mean of the rates offered as of 10:00 A.M., New York City time, on the relevant Interest Determination Date, by three leading nonbank dealers in negotiable U.S. dollar certificates of deposit in New York City, as selected by the Calculation Agent for negotiable U.S. dollar certificates of deposit of major U.S. money center banks with a remaining maturity closest to the specified Index Maturity, and in a Representative Amount.

(iii) If fewer than three dealers selected by the Calculation Agent are quoting as described above, the CD Rate in effect for the new Interest Reset Period will be the rate in effect for the prior Interest Reset Period.

Federal Funds Rate. If the Interest Rate Basis of this Subordinated Note is the Federal Funds Rate, this Subordinated Note will bear interest at a Base Rate equal to the Federal Funds Rate, as adjusted by the Spread or Spread Multiplier, if any, specified on the face hereof.

The Federal Funds Rate will be the rate for U.S. dollar federal funds on the relevant Interest Determination Date, as published in H.15(519) under the heading “Federal Funds (Effective),” as that rate is displayed on Reuters Screen FEDFUNDS1 Page. If the Federal Funds Rate cannot be determined in this manner, the following procedures will apply:

(i) If the rate described above is not displayed on Reuters Screen FEDFUNDS1 Page at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from that source at that time), then the Federal Funds Rate, for the relevant Interest Determination Date, will be the rate described above as published in H.15 Daily Update or another recognized electronic source used for displaying that rate, under the heading “Federal Funds (Effective).”

(ii) If the rate described above is not displayed on Reuters Screen FEDFUNDS1 Page and does not appear in H.15 Daily Update or another recognized electronic source at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from one of those sources at that time), the Federal Funds Rate will be the arithmetic mean of the rates for the last transaction in overnight, U.S. dollar federal funds arranged, before 9:00 A.M., New York City time, on the relevant Interest Determination Date, by three leading brokers of U.S. dollar federal funds transactions in New York City selected by the Calculation Agent.

(iii) If fewer than three brokers selected by the Calculation Agent are quoting as described above, the Federal Funds Rate in effect for the new Interest Reset Period will be the rate in effect for the prior Interest Reset Period.

Prime Rate. If the Interest Rate Basis of this Subordinated Note is the Prime Rate, this Subordinated Note will bear interest at a Base Rate equal to the Prime Rate, as adjusted by the Spread or Spread Multiplier, if any, specified on the face hereof.

The Prime Rate will be the rate, for the relevant Interest Determination Date, published in H.15(519) under the heading “Bank Prime Loan.” If the Prime Rate cannot be determined as described above, the following procedures will apply.

(i) If the rate described above does not appear in H.15(519) at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from that source at that time), then the Prime Rate will be the rate, for the relevant Interest Determination Date, as published in H.15 Daily Update or another recognized electronic source used for the purpose of displaying that rate, under the heading “Bank Prime Loan.”

(ii) If the rate described above does not appear in H.15(519), H.15 Daily Update or another recognized electronic source at 3:00 P.M., New York City time, on the relevant Interest Calculation Date (unless the calculation is made earlier and the rate is available from one of those sources at that time), then the Prime Rate will be the arithmetic mean of the rates of interest publicly announced by each bank appearing on the Reuters Screen US PRIME 1 Page (as defined below) as that bank’s prime rate or base lending rate, as of 11:00 A.M., New York City time, on the relevant Interest Determination Date.

(iii) If fewer than four of these rates appear on the Reuters Screen US PRIME 1 Page, the Prime Rate will be the arithmetic mean of the prime rates or base lending rates, as of the close of business on the relevant Interest Determination Date, of three major banks in New York City selected by the Calculation Agent. For this purpose, the Calculation Agent will use rates quoted on the basis of the actual number of days in the year divided by a 360-day year.

(iv) If fewer than three banks selected by the Calculation Agent are quoting as described above, the Prime Rate for the new Interest Reset Period will be the rate in effect for the prior Interest Reset Period.
