If no Default Rate is specified above, the Default Rate shall be the Interest Rate on this Senior Note specified above. The interest so payable, and punctually paid or duly provided for, on any Interest Payment Date will be paid to the person in whose name this Senior Note (or any predecessor Senior Note) is registered at the close of business on the Regular Record Date, which unless otherwise specified above shall be the fifteenth calendar day (whether or not a Business Day (as defined hereinafter)) next preceding the applicable Interest Payment Date (a “Regular Record Date”); provided, however, that interest payable at maturity or upon earlier redemption or repayment, if applicable, will be payable to the person to whom principal shall be payable. Any such interest not so punctually paid or duly provided for shall forthwith cease to be payable to the holder as of the close of business on such Regular Record Date and may either be paid to the person in whose name this Senior Note (or any predecessor Senior Note) is registered at the close of business on a special record date for the payment of such defaulted interest (the “Special Record Date”) to be fixed by the Bank, notice of which shall be given to the holders of Senior Notes not less than 10 calendar days prior to such Special Record Date, or be paid at any time in any other lawful manner.

Payment of principal of, premium, if any, and interest on, this Senior 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 an issuing and paying agent (which may be the Bank) (the “Issuing and Paying Agent”, which term shall include any successor Issuing and Paying Agent), authorized by the Bank to pay principal of, premium, if any, and interest on, this Senior Note on behalf of the Bank pursuant to an issuing and paying agency agreement (the “Issuing and Paying Agency Agreement”) and having an office or agency (the “Issuing and Paying Agent Office”) in The City of New York or the city in which the Bank is headquartered (the “Place of Payment”), where this Senior Note may be presented or surrendered for payment and where notices, designations or requests in respect of payments with respect to this Senior Note may be served.

[Reverse]

This Senior Note is one of a duly authorized issue of Senior Bank Notes of the Bank due nine months or more from date of issue (the “Senior Notes”).

If any Interest Payment Date (other than an Interest Payment Date at the Maturity Date or date of earlier redemption or repayment of this Senior Note) would otherwise fall on a day that is not a Business Day, such Interest Payment Date shall be postponed to the next succeeding day that is a Business Day, except that if an Interest Rate Basis is LIBOR, as specified on the face hereof, and such next Business Day falls in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding day that is a Business Day. Except as provided above, interest payments will be made on the Interest Payment Dates shown on the face hereof. If the Maturity Date or date of earlier redemption or repayment of this Senior Note falls on a day which is not a Business Day, the related payment of principal of, premium, if any, and interest on, this Senior Note will be made on the next succeeding Business Day with the same force and effect as if made on the date such payment was 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, as the case may be.

This Senior Note will not be subject to any sinking fund. If so provided on the face of this Senior Note, this Senior Note may be redeemed by the Bank in whole, but not in part, on the Initial Redemption Date, if any, specified on the face hereof. Any such redemption will apply to all outstanding Senior Notes of this series, whether or not the maturity of any or all of these Senior Notes has been extended. The Bank will provide notice to holders of its election to redeem the Senior Notes no more than 15 nor less than 10 calendar days prior to the Initial Redemption Date. If no Initial Redemption Date is specified on the face hereof, this Senior Note may not be redeemed prior to the Maturity Date.

The “Redemption Price” shall initially be the Initial Redemption Percentage specified on the face hereof of the principal amount of this Senior 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.

The interest rate borne by this Senior Note shall be determined as follows:

1. If this Senior Note is designated as a Regular Floating Rate Senior Note on the face hereof or if no designation is made for Interest Calculation on the face hereof, then, except as described below or in an Addendum hereto, this Senior Note shall bear interest at the rate determined by reference to the applicable Interest Rate Basis or Bases shown on the face hereof (i) plus or minus the applicable Spread, if any, and/or (ii) multiplied by the applicable Spread Multiplier, if any, specified and applied in the manner described on the face hereof. Commencing on the Initial Interest Reset Date, the rate at which interest on this Senior Note is

7

payable shall be reset as of each Interest Reset Date specified on the face hereof; provided, however, that the interest rate in effect for the period from the Original Issue Date to but excluding the Initial Interest Reset Date will be the Initial Interest Rate.

2. If this Senior Note is designated as a Floating Rate/Fixed Rate Senior Note on the face hereof then, except as described below or in an Addendum hereto, this Senior Note shall bear interest at the rate determined by reference to the applicable interest Rate Basis or Bases shown on the face hereof (i) plus or minus the applicable Spread, if any, and/or (ii) multiplied by the applicable Spread Multiplier, if any, specified and applied in the manner described on the face hereof. Commencing on the Initial Interest Reset Date, the rate at which interest on this Senior Note is payable shall be reset as of each Interest Reset Date specified on the face hereof; provided, however, that (i) the interest rate in effect for the period from the Original Issue Date to but excluding the Initial Interest Reset Date will be the Initial Interest Rate; and (ii) the interest rate in effect commencing on, and including, the Fixed Rate Commencement Date to but excluding the Stated Maturity Date or date of earlier redemption or repayment shall be the Fixed Interest Rate, if such a rate is specified on the face hereof, or if no such Fixed Interest Rate is so specified, the interest rate in effect hereon on the Business Day immediately preceding the Fixed Rate Commencement Date.

3. If this Senior Note is designated as an Inverse Floating Rate Senior Note on the face hereof, then, except as described below or in an Addendum hereto, this Senior Note shall bear interest equal to the Fixed Interest Rate specified on the face hereof minus the rate determined by reference to the applicable Interest Rate Basis or Bases shown on the face hereof (i) plus or minus the applicable Spread, if any, and/or (ii) multiplied by the applicable Spread Multiplier, if any, specified and applied in the manner described on the face hereof; provided, however, that, unless otherwise specified on the face hereof, the interest rate hereon will not be less than zero percent. Commencing on the Initial Interest Reset Date, the rate at which interest on this Senior Note is payable shall be reset as of each Interest Rate Reset Date specified on the face hereof; provided, however, that the interest rate in effect for the period from the Original Issue Date to but excluding the Initial Interest Reset Date will be the Initial Interest Rate.

Notwithstanding the foregoing, if this Senior Note is designated on the face hereof as having an Addendum attached, this Senior Note shall bear interest in accordance with the terms described in such Addendum.

Except as set forth above or specified on the face hereof or in an Addendum hereto, the interest rate in effect on each day shall be (i) if such day is an Interest Reset Date, the interest rate determined as of the Interest Determination Date (as defined hereinafter) immediately preceding such Interest Reset Date or (ii) if such day is not an Interest Reset Date, the interest rate determined as of the Interest Determination Date immediately preceding the most recent Interest Reset Date. If any Interest Reset Date would otherwise be a day that is not a Business Day, such Interest Reset Date shall be postponed to the next succeeding day that is a Business Day, except that if LIBOR is an applicable Interest Rate Basis and if such Business Day falls in the next succeeding calendar month, such Interest Reset Date will be the immediately preceding Business Day. In addition, if the Treasury Rate is an applicable Interest Rate Basis and the Interest Determination Date would otherwise fall on an Interest Reset Date, then such Interest Reset Date will be postponed to the next succeeding Business Day.

8

Unless otherwise specified on the face hereof, interest payable on this Senior Note on any Interest Payment Date will equal the amount of interest accrued from and including the next preceding Interest Payment Date in respect of which interest has been paid (or from and including the Original Issue Date specified on the face hereof, if no interest has been paid), to but excluding the related Interest Payment Date or Maturity Date or date of earlier redemption or repayment, as the case may be.

Unless otherwise specified on the face hereof, accrued interest hereon shall be an amount calculated by multiplying the face amount hereof by an accrued interest factor. Such accrued interest factor is computed by adding the interest factor calculated for each day in the period for which interest is being calculated. Unless otherwise specified on the face hereof, the interest factor for each such date will be computed by dividing the interest rate applicable to such day by 360 if the Commercial Paper Rate, the Federal Funds Rate, LIBOR or the Prime Rate is an applicable Interest Rate Basis or by the actual number of days in the year if the CMT Rate or the Treasury Rate is an applicable Interest Rate Basis. Unless otherwise specified on the face hereof, the interest factor for this Senior Note, if the interest rate is calculated with reference to two or more Interest Rate Bases, will be calculated in each period in the same manner as if only the applicable Interest Rate Bases specified on the face hereof applied.

The interest rate applicable to each day in an Interest Reset Period commencing on the related Interest Reset Date will be determined by the Calculation Agent as of the applicable Interest Determination Date and will be calculated by the Calculation Agent on or prior to the Calculation Date (as defined hereinafter), except with respect to LIBOR, which will be calculated on such Interest Determination Date. The “Interest Determination Date” with respect to the CMT Rate, the Commercial Paper Rate, the Federal Funds Rate and the Prime Rate will be the second Business Day immediately preceding the applicable Interest Reset Date; and the “Interest Determination Date” with respect to LIBOR shall be the second London Banking Day (as defined hereinafter) immediately preceding the applicable Interest Reset Date, unless the Designated LIBOR Currency is British pounds sterling, in which case the “Interest Determination Date” will be the applicable Interest Reset Date. The “Interest Determination Date” with respect to the Treasury Rate shall be the day in the week in which the applicable Interest Reset Date falls on which day Treasury Bills (as defined hereinafter) are normally auctioned (Treasury Bills are normally sold at an auction held on Monday of each week, unless that day is a legal holiday, in which case the auction is normally held on the following Tuesday, except that such auction may be held on the preceding Friday); provided, however, that if an auction is held on the Friday of the week preceding the applicable Interest Reset Date, the “Interest Determination Date” shall be such preceding Friday; provided, further, that if the Interest Determination Date would otherwise fall on an Interest Reset Date, then such Interest Reset Date will be postponed to the next succeeding Business Day. If the interest rate of this Senior Note is determined with reference to two or more Interest Rate Bases specified on the face hereof, the “Interest Determination Date” pertaining to this Senior Note shall be the latest Business Day which is at least two Business Days prior to the applicable Interest Reset Date on which each Interest Rate Basis is determinable. Each Interest Rate Basis shall be determined as of such date, and the applicable interest rate shall take effect on the related Interest Reset Date.

Unless otherwise specified on the face hereof, the “Calculation Date” pertaining to any Interest Determination Date will be the earlier of (i) the tenth calendar day after such Interest

9

Determination Date or, if such day is not a Business Day, the next succeeding Business Day and (ii) the Business Day immediately preceding the applicable Interest Payment Date or Maturity Date or date of earlier redemption or repayment, as the case may be. All calculations on this Senior Note shall be made by the Calculation Agent specified on the face hereof or such successor thereto as is duly appointed by the Bank. The determination of any interest rate by the Calculation Agent will be final and binding absent manifest error.

All percentages resulting from any calculation on this Senior Note will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., 9.876545% (or 0.09876545) would be rounded to 9.87655% (or 0.0987655) and 9.876544% (or 0.09876544) would be rounded to 9.87654% (or 0.0987654)), and all dollar amounts used in or resulting from such calculation will be rounded, in the case of United States dollars, to the nearest cent or, in the case of a foreign currency, to the smallest denominational unit (with one-half cent being rounded upwards).

As used herein, “Business Day” means, unless otherwise specified on the face hereof, any day that is not a Saturday or Sunday and that in The City of New York and in Pittsburgh, Pennsylvania is not a day on which banking institutions are authorized or required by law, regulation or executive order to close and, if an Interest Rate Basis shown on the face hereof is LIBOR, is also a London Banking Day.

As used herein, unless otherwise specified on the face hereof, “London Banking Day” means any day on which dealings in deposits in U.S. dollars are transacted in the London interbank market.

CMT Rate. If an Interest Rate Basis for this Senior Note is the CMT Rate, as specified on the face hereof, the CMT Rate shall be determined by the Calculation Agent as of the applicable Interest Determination Date (a “CMT Rate Interest Determination Date”) in accordance with the following provisions:

(i) If “CMT Moneyline Telerate Page 7051” is specified on the face hereof, the CMT Rate on the CMT Rate Interest Determination Date shall be a percentage equal to the yield for United States Treasury securities at “constant maturity” having the Index Maturity specified on the face hereof as set forth in H.15(519) (as defined hereinafter) under the caption “Treasury Constant Maturities”, as such yield is displayed on Moneyline Telerate (or any successor service) on page 7051 (or any other page as may replace such page on such service) (“Moneyline Telerate Page 7051”) for such CMT Rate Interest Determination Date. If such rate does not appear on Moneyline Telerate Page 7051, the CMT Rate on such CMT Rate Interest Determination Date shall be a percentage equal to the yield for United States Treasury securities at “constant maturity” having the Index Maturity specified on the face hereof and for such CMT Rate Interest Determination Date as set forth in H.15(519) under the caption “Treasury Constant Maturities”. If such rate does not appear in H.15(519), the CMT Rate on such CMT Rate Interest Determination Date shall be the rate for the period of the Index Maturity specified on the face hereof as may then be published by either the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) or the United States Department of the Treasury that the Calculation Agent determines to be comparable to the rate which would otherwise have been published in H.15(519). If the Federal Reserve Board or the United States Department of the

10

Treasury does not publish a yield on United States Treasury securities at “constant maturity” having the Index Maturity specified on the face hereof for such CMT Rate Interest Determination Date, the CMT Rate on such CMT Rate Interest Determination Date shall be calculated by the Calculation Agent and shall be a yield-to-maturity based on the arithmetic mean of the secondary market bid prices at approximately 3:30 P.M., New York City time, on such CMT Rate Interest Determination Date of three leading primary United States government securities dealers in The City of New York (which may include the Dealers or their affiliates) (each, a “Reference Dealer”) selected by the Calculation Agent (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)) for United States Treasury securities with an original maturity equal to the Index Maturity specified on the face hereof, a remaining term to maturity no more than 1 year shorter than the Index Maturity specified on the face hereof and in a principal amount that is representative for a single transaction in such securities in such market at such time. If fewer than five but more than two such prices are provided as requested the CMT Rate on such CMT Rate Interest Determination Date shall be calculated by the Calculation Agent and shall be based on the arithmetic mean of the bid prices obtained and neither the highest nor the lowest of such quotations shall be eliminated. If fewer than three prices are provided as requested, the CMT Rate on such CMT Rate Interest Determination Date shall be calculated by the Calculation Agent and shall be a yield-to-maturity based on the arithmetic mean of the secondary market bid prices as of approximately 3:30 P.M., New York City time, on such CMT Rate Interest Determination Date of three Reference Dealers selected by the Calculation Agent (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)) for United States Treasury securities with an original maturity greater than the Index Maturity specified on the face hereof, a remaining term to maturity closest to the Index Maturity specified on the face hereof and in a principal amount that is representative for a single transaction in such securities in such market at such time. If fewer than five but more than two such prices are provided as requested, the CMT Rate on such CMT Rate Interest Determination Date shall be calculated by the Calculation Agent and shall be based on the arithmetic mean of the bid prices obtained and neither the highest nor the lowest of such quotations shall be eliminated; provided, however, that if fewer than three such prices are provided as requested, the CMT Rate determined as of such CMT Rate Interest Determination Date shall be the CMT Rate in effect on such CMT Rate Interest Determination Date. If two such United States Treasury securities with an original maturity greater than the Index Maturity specified on the face hereof have remaining terms to maturity equally close to the Index Maturity specified on the face hereof, the quotes for the Treasury security with the shorter original term to maturity will be used.

(ii) If “CMT Moneyline Telerate Page 7052” is specified on the face hereof, the CMT Rate on the CMT Rate Interest Determination Date shall be a percentage equal to the one-week or one-month, as specified on the face hereof, average yield for United States Treasury securities at “constant maturity” having the Index Maturity specified on the face hereof as set forth in H.15(519) opposite the caption “Treasury Constant Maturities”, as such yield is displayed on Moneyline Telerate (or any successor service) on page 7052 (or any other page as may replace such page on such service ) (“Moneyline Telerate Page 7052”) for the week or month, as applicable, ended immediately preceding the week or month, as applicable, in which such CMT

11

Rate Interest Determination Date falls. If such rate does not appear on the Moneyline Telerate Page 7052, the CMT Rate on such CMT Rate Interest Determination Date shall be a percentage equal to the one-week or one-month, as specified on the face hereof, average yield for United States Treasury securities at “constant maturity” having the Index Maturity specified on the face hereof and for the week or month, as applicable, preceding such. CMT Rate Interest Determination Date as set forth in H.15(519) opposite the caption “Treasury Constant Maturities”. If such rate does not appear in H.15(519), the CMT Rate on such CMT Rate Interest Determination Date shall be the one-week or one-month, as specified on the face hereof, average yield for United States Treasury securities at “constant maturity” having the Index Maturity specified on the face hereof as otherwise announced by the Federal Reserve Bank of New York for the week or month, as applicable, ended immediately preceding the week or month, as applicable, in which such CMT Rate Interest Determination Date falls. If the Federal Reserve Bank of New York does not publish a one-week or one-month, as specified on the face hereof, average yield on United States Treasury securities at “constant maturity” having the Index Maturity specified on the face hereof for the applicable week or month, the CMT Rate on such CMT Rate Interest Determination Date shall be calculated by the Calculation Agent and shall be a yield-to-maturity based on the arithmetic mean of the secondary market bid prices at approximately 3:30 P.M., New York City time, on such CMT Rate Interest Determination Date of three Reference Dealers selected by the Calculation Agent (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)) for United States Treasury securities with an original maturity equal to the Index Maturity specified on the face hereof, a remaining term to maturity of no more than 1 year shorter than the Index Maturity specified on the face hereof and in a principal amount that is representative for a single transaction in such securities in such market at such time. If fewer than five but more than two such prices are provided as requested, the CMT Rate on such CMT Rate Interest Determination Date shall be the rate on the CMT Rate Interest Determination Date calculated by the Calculation Agent based on the arithmetic mean of the bid prices obtained and neither the highest nor lowest of such quotations shall be eliminated. If fewer than three prices are provided as requested, the CMT Rate on such CMT Rate Interest Determination Date shall be calculated by the Calculation Agent and shall be a yield-to-maturity based on the arithmetic mean of the secondary market bid prices as of approximately 3:30 P.M., New York City time, on such CMT Rate Interest Determination Date of three Reference Dealers selected by the Calculation Agent (from five such Reference Dealers selected by the Calculation Agent and eliminating the highest quotation (or, in the event of equality, one of the highest) and the lowest quotation (or, in the event of equality, one of the lowest)) for United States Treasury securities with an original maturity greater than the Index Maturity specified on the face hereof, a remaining term to maturity closest to the Index Maturity specified on the face hereof and in a principal amount that is representative for a single transaction in such securities in such market at such time. If fewer than five but more than two such prices are provided as requested, the CMT Rate on such CMT Rate Interest Determination Date shall be the rate on the CMT Rate Interest Determination Date calculated by the Calculation Agent based on the arithmetic mean of the bid prices obtained and neither the highest nor lowest of such quotations shall be eliminated; provided, however, that if fewer than three such prices are provided as requested, the CMT Rate determined as of such CMT Rate interest Determination Date shall be the CMT Rate in effect on such CMT Rate interest Determination Date. If two United States Treasury securities with an

12

original maturity greater than the Index Maturity specified on the face hereof have remaining terms to maturity equally close to the Index Maturity specified on the face hereof, the quotes for the Treasury security with the shorter original term to maturity will be used.

“H.15(519)” means the weekly statistical release designated as such, or any successor publication, published by the Federal Reserve Board.

Commercial Paper Rate. If an Interest Rate Basis for this Senior Note is the Commercial Paper Rate, as specified on the face hereof, the Commercial Paper Rate shall be determined as of the applicable Interest Determination Date (a “Commercial Paper Rate Interest Determination Date”) as the Money Market Yield (as defined hereinafter) on such date of the rate for commercial paper having the Index Maturity specified on the face hereof as published in H.15(519) under the caption “Commercial Paper-Nonfinancial” or, if not so published by 3:00 P.M., New York City time, on the related Calculation Date, the Money Market Yield of the rate on such Commercial Paper Rate Interest Determination Date for commercial paper having the Index Maturity specified on the face hereof as published in H.15 Daily Update (as defined hereinafter), or such other recognized electronic source used for the purpose of displaying such rate, under the caption “Commercial Paper-Nonfinancial.” If such rate is not yet published in H.15(519), H.15 Daily Update or another recognized electronic source by 3:00 P.M., New York City time, on such Calculation Date, then the Commercial Paper Rate on such Commercial Paper Rate Interest Determination Date will be calculated by the Calculation Agent and will be the Money Market Yield of the arithmetic mean of the offered rates at approximately 11:00 A.M., New York City time, on such Commercial Paper Rate Interest Determination Date of three leading dealers of United States dollar commercial paper in The City of New York (which may include the Dealers or their affiliates) selected by the Calculation Agent for commercial paper having the Index Maturity specified on the face hereof placed for industrial issuers whose bond rating is “Aa,” or the equivalent, from a nationally recognized statistical rating organization; provided, however, that if the dealers so selected by the Calculation Agent are not quoting as mentioned in this sentence, the Commercial Paper Rate determined as of such Commercial Paper Rate Interest Determination Date will be the Commercial Paper Rate in effect on such Commercial Paper Rate Interest Determination Date.

“H.15 Daily Update” means the daily update of H.15(519), available through the world-wide-web site of the Federal Reserve Board at http://www.federalreserve.gov/releases/h15/update, or any successor site or publication.

Therefore, a holder must exercise the option to extend the maturity of its Senior Notes through the Depositary. To ensure that the Depositary will receive timely notice of a holder’s election to extend the maturity of all or a portion of its Senior Notes, or its subsequent revocation of such an election, such holder must instruct the direct or indirect participant through which it holds an interest in the Senior Notes to notify the Depositary of its election to extend the maturity of its Senior Notes, or to revoke any such election, in accordance with the then applicable operating procedures of the Depositary.
