MEDIUM-TERM NOTE, SERIES C

(FLOATING RATE)

This Security is one of a duly authorized issue of securities of the Company (herein called the “Securities”), issued and to be issued in one or more series under an Indenture dated as of December 15, 1987, as supplemented by a First Supplemental Indenture dated as of October 1, 1990 (the Indenture as so supplemented being herein called the “Indenture”), between the Company and U.S. Bank National Association, as successor trustee (herein called the “Trustee”, which term includes any successor trustee under the Indenture), to which Indenture and all indentures supplemental thereto reference is hereby made for a statement of the respective rights, limitations of rights, duties and immunities thereunder of the Company, the Trustee and the Holders of the Securities and of the terms upon which the Securities are, and are to be, authenticated and delivered. This Security is one of the series designated on the face hereof, which series is unlimited in aggregate principal amount.

Each Security of this series shall be dated the date of its authentication by the Trustee. Each Security of this series shall also bear an Original Issue Date, as specified on the face hereof, and such Original Issue Date shall remain the same for all Securities subsequently issued upon transfer, exchange or substitution of such original Security (or such subsequently issued Securities) regardless of their dates of authentication.

Unless one or more Redemption Dates are specified on the face hereof, this Security shall not be redeemable at the option of the Company before the Stated Maturity specified on the face hereof. If one or more Redemption Dates (or ranges of Redemption Dates) are so specified, this Security is subject to redemption on any such date (or during any such range) at the option of the Company, upon notice by first-class mail, postage prepaid, mailed not less than 30 days nor more than 60 days prior to the Redemption Date specified in such notice, at the applicable Redemption Price specified on the face hereof (expressed as a percentage of the principal amount of this Security), together in the case of any such redemption with accrued interest to the Redemption Date, but interest installments whose Stated Maturity is prior to the Redemption Date will be payable to the Holder of this Security, or one or more Predecessor Securities, of record at the close of business on the relevant Regular or Special Record Dates, all as provided in the Indenture. The Company may elect to redeem less than the entire principal amount hereof, provided that the principal amount, if any, of this Security that remains outstanding after such redemption is an Authorized Denomination as defined herein. In the event of any redemption in part, the Company will not be required to (i) issue, register the transfer of, or exchange any Security during a period of 15 days next preceding the day of the first mailing of the notice of redemption of Securities selected for redemption or (ii) register the transfer or exchange of any Security, or any portion thereof, called for redemption, except the unredeemed portion of any Security being redeemed in part.

Unless one or more Repayment Dates is specified above, this Security shall not be repayable at the option of the Holder on any date prior to the Stated Maturity specified above. If one or more Repayment Dates (or ranges of Repayment Dates) are so specified, this Security is subject to repayment on any such date (or during any such range) at the option of the Holder at a price equal to 100% of the principal amount hereof or, if this Security is a Discounted Security (as specified on the face hereof), the applicable Repayment Price specified on the face hereof (expressed as a percentage of the principal amount of this Security), together in the case of any such repayment with accrued interest to the Repayment Date, but interest installments whose Stated Maturity is prior to the Repayment Date will be payable to the Holder of this Security, or one or more Predecessor Securities, of record at the close of business on the relevant Regular or Special Record Dates, all as provided in the Indenture. For this Security to be repaid at the option of the Holder, the Paying Agent must receive at least 30 days but not more than 60 days prior to the Repayment Date on which this Security is to be repaid, (a) appropriate wire transfer instructions and (b) either (i) this Security with the form entitled “Option to Elect Repayment” below duly completed or (ii) a telegram, telex, facsimile transmission or a letter from a member of a national securities exchange, or the Financial Industry Regulatory Authority, Inc. or a commercial bank or trust company in the United States setting forth the name of the Holder of this Security, the principal amount of this Security, the portion of principal amount of this Security to be repaid, the certificate number or a description of the tenor and terms of this Security, a statement that the option to

4

elect repayment is being exercised thereby and a guarantee that this Security, together with the duly completed form entitled “Option to Elect Repayment” on this Security, will be received by the Paying Agent not later than the fifth Business Day after the date of such telegram, telex, facsimile transmission or letter, provided, however, that such Security and form duly completed is received by the Paying Agent by such fifth Business Day. Exercise of the repayment option by the Holder shall be irrevocable, except a Holder who has tendered this Security for repayment pursuant to a Reset Notice or an Extension Notice (each as defined in the Prospectus Supplement related hereto). The repayment option with respect to this Security may be exercised by the Holder for less than the entire principal amount hereof, provided that the principal amount, if any, of this Security that remains outstanding after such repayment must be an authorized denomination as defined herein. The Company will not be required to register the transfer or exchange of any Security following the receipt of a notice to repay a Security as described above. All questions as to the validity, eligibility (including time of receipt) and acceptance of any Security for repayment will be determined by the Trustee, whose determination will be final, binding and non-appealable.

In the event of redemption or repayment of this Security in part only, a new Security or Securities of this series and of like tenor and for a principal amount equal to the unredeemed or unrepaid portion will be delivered to the registered Holder upon the cancellation hereof.

If so specified above, the Stated Maturity of this Security may be extended at the option of the Company, in the manner set forth below (unless otherwise provided on the face hereof), for the period or periods specified above (each an “Extension Period”) up to but not beyond the date (the “Final Maturity Date”) set forth above:

(a) The Company may exercise such option by notifying the Paying Agent of such exercise at least 45 but no more than 60 days prior to the Stated Maturity in effect prior to such exercise (the “Original Stated Maturity”). If the Company exercises such option, the Paying Agent will mail by first-class mail, postage pre-paid, to the Holder of this Security no later than 40 days prior to the Original Stated Maturity a notice setting forth (i) the election of the Company to extend the Original Stated Maturity, (ii) the new Stated Maturity (which shall then be considered the Stated Maturity for all purposes of this Security), (iii) the Spread and/or Spread Multiplier applicable to the Extension Period and (iv) the provisions, if any, for redemption during such Extension Period, including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during the Extension Period. Upon the Paying Agent’s transmittal of the Extension Notice, the Original Stated Maturity of this Security shall be extended automatically, and, except as modified by the Extension Notice and as described in the next paragraph, this Security will have the same terms as prior to the transmittal of such Extension Notice.

(b) Notwithstanding the foregoing, not later than 20 days prior to the Original Stated Maturity of this Security the Company may, at its option, revoke the Spread and/or Spread Multiplier provided for in the Extension Notice and establish a Spread and/or Spread Multiplier that is higher than the Spread and/or Spread Multiplier provided for in the Extension Notice for the Extension Period by mailing or causing the Paying Agent to transmit notice, by first class mail, postage prepaid, of such higher Spread and/or Spread Multiplier to the Holder of this Security. Such notice shall be irrevocable. All Securities with respect to which the Stated Maturity is extended will bear such higher Spread and/or Spread Multiplier for the Extension Period.

(c) If the Company elects to extend the Stated Maturity of this Security, the Holder hereof will have the option to elect repayment of this Security by the Company on the Original Stated Maturity at a price equal to the principal amount hereof plus interest accrued to such date. In order for this Security to be so repaid on the Original Stated Maturity, the Holder hereof must follow the procedures set forth above for optional repayment, except that the period for delivery of this Security or notification to the Paying Agent shall be at least 25 but not more than 35 days prior to the Original Stated Maturity and except that, if the Holder hereof has tendered this Security for repayment pursuant to an Extension Notice, such Holder may, by written notice to the Paying Agent, revoke such tender for repayment until the close of business on the tenth day prior to the Original Stated Maturity.

If so specified above, this Security may be renewed by the Holder of the Security on an Interest Payment Date (specified above) occurring in or prior to the twelfth month following the Original Issue Date (the “Initial Maturity Date”) in accordance with the procedures described below:

(a) On the Interest Payment Date occurring in the sixth month (unless a different interval (the “Special Election Interval”) is specified above) prior to the Initial Maturity Date (as specified above) of a Renewable Note (the “Initial Renewal Date”) and on the Interest Payment Date occurring in each sixth month (or in the last month of each Special Election Interval) after such Initial Renewal Date (each, together with the Initial Renewal Date, a “Renewal Date”), the term of this Security may be extended to the Interest Payment Date occurring in the twelfth month (or, if a Special Election Interval is specified the last month in a period equal to twice the Special Election Interval) after such Renewal Date, if the Holder of this Security elects to extend the term of this Security or any portion hereof as provided below. If the Holder of this Security does not elect to extend the term of any portion of the principal amount of this Security during the specified period prior to any Renewal Date, such portion will become due and payable on the Interest Payment Date occurring in the sixth month (or the last month in the Special Election Interval) after such Renewal Date (the “New Maturity Date”).

(b) A Holder of this Security may elect to renew the term of this Security, or if specified above, any portion thereof, by delivering a notice to such effect to the Trustee (or any duly appointed Paying Agent) at the Corporate Trust Office not less than 15 nor more than 30 days prior to such Renewal Date (unless another period is specified above as the “Special Election Period”). Such election will be irrevocable and will be binding upon each subsequent Holder of this Security. An election to renew the term of this Security may be exercised with respect to less than the entire principal amount of this Security only if so specified above and only in such principal amount, or any integral multiple in excess thereof, as specified above. Notwithstanding the foregoing, the term of this Security may not be extended beyond the Stated Maturity specified above.

(c) If the Holder of this Security does not elect to renew this Security, this Security must be presented to the Trustee (or any duly appointed Paying Agent) simultaneously with notice of such election (or, in the event notice of such election, together with a guarantee of delivery within five Business Days, is transmitted on behalf of the Holder hereof from a member of a national securities exchange, the Financial Industry Regulatory Authority, Inc. or a commercial bank or trust company in the United States, within five Business Days of the date of such notice). As soon as practicable following receipt of this Security the Trustee (or any duly appointed Paying Agent) will issue in exchange of this Security in the name of the Holder hereof (i) a Security, in a principal amount equal to the principal amount of this Security for which the election to renew the term hereof was exercised, with terms identical to those specified on this Security (except for the Original Issue Date and the Initial Interest Rate and except that such Security will have a fixed, nonrenewable Stated Maturity on the New Maturity Date) and (ii) if such election is made with respect to less than the full principal amount of this Security, a replacement Security in a principal amount equal to the principal amount of this Security for which the election was made, with terms identical to this Security.

If so specified above, the Spread and/or Spread Multiplier of this Security may be reset at the option of the Company on the date set forth on the face hereof (each an “Optional Reset Date”) in accordance with the procedures described below):

(a) The Company may exercise such option by notifying the Paying Agent of such exercise at least 45 but not more than 60 days prior to an Optional Reset Date set forth on the face hereof. If the Company exercises such option, the Paying Agent will mail by first-class mail, postage prepaid, to the Holder of this Security not later than 40 days prior to such Optional Reset Date a notice (the “Reset Notice”) setting forth (i) the election of the Company to reset the Spread and/or Spread Multiplier of this Security, (ii) such new Spread and/or Spread Multiplier, and (iii) the provisions, if any, for redemption of this Security during the period from such Optional Reset Date to the next Optional Reset Date or, if there is no such next Optional Reset Date, to the Stated Maturity of this Security (each such period a “Subsequent Period”), including the date or dates on which or the period or periods during which and the price or prices at which such redemption may occur during such Subsequent Interest Period.

(b) Notwithstanding the foregoing, not later than 20 days prior to an Optional Reset Date of this Security, the Company may, at its option, revoke the Spread and/or Spread Multiplier provided for in the Reset Notice and establish a Spread and/or Spread Multiplier that is higher for the Subsequent Interest Period commencing on such Optional Reset Date by mailing or causing the Paying Agent to mail notice of such higher Spread and/or Spread Multiplier by first class mail, postage prepaid, to the Holder of this Security. Such notice shall be irrevocable. All Securities with respect to which the Spread and/or Spread Multiplier is reset on an Optional Reset Date will bear such higher Spread and/or Spread Multiplier.

6

(c) If the Company elects to reset the Spread and/or Spread Multiplier of this Security, the Holder of this Security will have the option to elect repayment of this Security by the Company on any Optional Reset Date at a price equal to the principal amount hereof plus interest accrued to such Optional Reset Date. In order for this Security to be so repaid on an Optional Reset Date, the Holder hereof must follow the procedures set forth above for optional repayment, except that the period for delivery of this Security or notification to the Paying Agent shall be a least 25 but not more than 35 days prior to such Optional Reset Date and except that, if the Holder hereof has tendered this Security for repayment pursuant to a Reset Notice, such Holder may, by written notice to the Paying Agent, revoke such tender for repayment until the close of business on the tenth day prior to such Optional Reset Date.

Commencing with the first interest payment date specified on the face hereof following the Original Issue Date, the rate at which interest on this Security is payable shall be reset daily, weekly, monthly, quarterly, semi-annually or annually (each an “Interest Reset Date”) as shown on the face hereof under Interest Rate Reset Period; provided, however, that (i) the interest rate in effect from the Original Issue Date to the first Interest Payment Date will be the Initial Interest Rate selected on the face hereof and (ii) unless otherwise specified above, the interest rate in effect hereon for the ten days immediately prior to the Maturity hereof shall be that in effect on the 10th day preceding such Maturity hereof. Each such adjusted rate shall be applicable on and after the Interest Reset Date to which it relates to but not including the next succeeding Interest Reset Date or until Maturity. If any Interest Reset Date specified on the face hereof would otherwise be a day that is not a Business Day (as defined below), such Interest Reset Day shall be postponed to the next day that is a Business Day, except that if (i) the rate of interest on this Security shall be determined in accordance with the provisions under the heading “Determination of LIBOR” below, and (ii) such Business Day is in the next succeeding calendar month limit, such Interest Reset Date shall be the immediately preceding Business Day. Subject to applicable provisions of law and except as specified herein, on each Interest Reset Date, the sum of interest on this Security shall be the sum determined in accordance with the provisions under the applicable heading below.

The interest rate on this Security will in no event be higher than the interest rate permitted by New York law as the same may be modified by United States law of general applicability. Under present New York law, subject to certain exceptions, the maximum rate of interest for any loan less than $250,000 is 16% per annum and for any Loan in the amount of $250,000 or more but less than $2,500,000 is 25% on a simple interest basis.

If not so published by 3:00 p.m., New York City time, on the Calculation Date pertaining to such

9

Interest Determination Date, the Fed Funds Rate will be the rate on such Interest Determinate Date as published in H.15 Daily Update, or another recognized electronic source used for the purpose of displaying that rate, under the caption “Federal Funds (Effective)”.

DETERMINATION OF CD RATE. Unless otherwise specified above, “CD Rate” means, with respect to each Interest Determination Date specified on the face hereof, the rate on such date for negotiable U.S. dollar certificates of deposit having the Index Maturity specified on the face hereof as published in H.15(519) under the heading “CDs (Secondary Market)” or, if not so published by 3:00 p.m., New York City time, on the Calculation Date pertaining to such Interest Determination Date, the CD Rate will be the rate on such Interest Determination Date for U.S. dollar negotiable certificates of deposit of the Index Maturity specified on the face hereof as published in H.15 Daily Update, or other recognized electronic sources used for the purpose of displaying the applicable rate, under the caption “CDs (Secondary Market)”.

All percentages resulting from any calculation on this Security will be rounded to the nearest one hundred-thousandth of a percentage point, with five one millionths of a percentage point rounded upwards, and all dollar amounts used in or resulting from such calculation on this Security will be rounded to the nearest cent (with one-half cent being rounded upward).

The Calculation Agent will upon the request of the Holder of this Security provide to such Holder the interest rate hereon then in effect and if different the interest rate which will become effective as a result of a determination made on the most recent Interest Determination Date (outlined below) specified on the face hereof.

If any Interest Payment Date specified hereof would otherwise be a day that is not a business day, the Interest Payment Date shall be postponed to the next day that is a Business Day, except that if (i) the rate of interest on the Security shall be determined in accordance with the provisions of the heading “Determination of LIBOR” above, and (ii) such Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding Business Day. If the Maturity Date falls on a day that is not a Business Day, the payment of principal, premium, if any, and interest will be made on the next succeeding Business Day as if made on the date such payment was due, and no interest on such payment will accrue.

“Business Day” means (i) any day that is not a Saturday or Sunday and that in The City of New York is not a day on which banking institutions generally are authorized or obligated by or pursuant to law, regulation or executive order to close and (ii) only if the rate of interest on the Security should be determined in accordance with the provisions of the heading “Determination of LIBOR” above, any such day on which dealings on deposit in U.S. dollars are transacted on the London interbank market (a “London Business Day”).

The date as of which the Interest Rate will be determined (the “Interest Determination Date”) for each Interest Reset Date if the rate of interest on this Security shall be determined in accordance with the provisions under the heading “Determination of Commercial Paper Rate”, “Determination of Prime Rate”, “Determination of Fed Funds Rate”, or “Determination of CD Rate” above will be the second Business Day preceding such Interest Reset Date. The Interest Determination Date pertaining to an Interest Reset Date if the rate of interest on this Security shall be determined in accordance with the provisions of the heading “Determination of LIBOR” above will be the second London Business Day preceding such Interest Reset Date. The Interest Determination Date pertaining to an Interest Reset Date if the rate of interest of the Security shall be determined in accordance with the provisions of the heading “Determination of Treasury Rate” above (the “Treasury Interest Determination Date”) will be the day of the week in which such Interest Reset Date falls on which Treasury Bills would normally be auctioned. Treasury Bills are normally sold at auction 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. If, as the result of a legal holiday, an auction is so held on the preceding Friday, such Friday will be the Treasury Interest Determination Date pertaining to the Interest Reset Date occurring in the next succeeding week. If an auction date for Treasury Bills should fall on any Interest Reset Date, then such Interest Reset Date shall instead be the first Business Day immediately following such auction date.

Interest payments for this Security will include interest accrued from and including the most recent date in respect of which interest has been paid or duly provided for (or from and including the Original Issue Date, if no interest has been paid with respect to this Security) to, but excluding the Interest Payment Date (or Maturity Date); provided, however, that if the Interest Reset Dates with respect to the Security are daily or weekly, interest payable on any Interest Payment Date, other than interest payable on any date on which principal hereof is payable, will include interest accrued from but excluding the most recent Regular Record Date in respect of which interest has been paid or duly provided for, or from and including the date of issue, to and including the next preceding Regular Record Date, provided however, that interest payments for this Security at Maturity will include interest accrued to but excluding the Maturity Date. Accrued interest hereon from the Original Issue Date or from the last date to which interest hereon has been paid, as the case may be, shall be an amount calculated by multiplying the face amount hereof by an accrued interest factor. Such accrued interest factor shall be computed by adding the interest factors calculated for each day in the period for which accrued interest is being calculated. The interest factor for each such day shall be computed by dividing the interest rate applicable to such day by 360, in the case of the Commercial Paper Rate, Prime Rate, LIBOR, Fed Funds Rate or CD Rate, or by the actual number of days in the year, in the case of the Treasury Rate.

The Company at its option, subject to the terms and conditions provided in the Indenture, (a) will be discharged from any and all obligations in respect of the Securities (except for certain obligations including obligations to register the transfer or exchange of Securities, replace stolen, lost or mutilated Securities, maintain paying agencies and hold moneys for payment in trust) or (b) need not comply with certain restrictive covenants of the Indenture after the Company deposits with the Trustee (or, in certain circumstances, 91 days after the Company deposits with the Trustee), pursuant to an escrow trust agreement, money or U.S. Government Obligations, or a combination of money and U.S. Government Obligations, which through the payment of interest thereon and principal thereof in accordance with their terms will provide money in an amount sufficient to pay all the principal of, and interest on, the Securities on the dates such payments are due in the currency, currencies or currency unit or units, in which such Securities are payable and in accordance with the terms of the Securities.

If an Event of Default with respect to Securities of this series shall occur and be continuing, the principal of the Securities of this series may be declared due and payable in the manner and with the effect provided in the Indenture.

The Indenture permits, with certain exceptions as therein provided, the amendment thereof and the modification of the rights and obligations of the Company and the rights of the Holders of the Securities of each series to be affected under the Indenture at any time by the Company and the Trustee with the consent of the Holders of not less than a majority in principal amount of the Outstanding Securities of all series affected thereby (acting as one class). The Indenture also contains provisions permitting the Holders of not less than a majority in principal

11

amount of the Outstanding Securities of all series affected thereby (acting as one class), on behalf of the Holders of all Securities of each such series, to waive compliance by the Company with certain provisions of the Indenture. The Indenture also provides that, regarding the Securities of any series, the Holders of not less than a majority in principal amount of the Outstanding Securities of such series may waive certain past defaults and their consequences on behalf of the Holders of all Securities of such series. Any such consent or waiver by the Holder of this Security shall be conclusive and binding upon such Holder and upon all future Holders of this Security and of any Security 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 Security.

As set forth in, and subject to, the provisions of the Indenture, no Holder of any Security of this series will have any right to institute any proceeding with respect to the Indenture or for any remedy thereunder, unless such Holder shall have previously given to the Trustee written notice of a continuing Event of Default with respect to this series, the Holders of not less than 25% in principal amount of the Outstanding Securities of this series shall have made written request, and offered reasonable indemnity, to the Trustee to institute such proceeding as trustee, the Trustee shall not have received from the Holders of a majority in principal amount of the Outstanding Securities of this series a direction inconsistent with such request and the Trustee shall have failed to institute such proceeding within 60 days; provided, however, that such limitations do not apply to a suit instituted by the Holder hereof for the enforcement of payment of the principal of (and premium, if any) or interest on this Security on or after the respective due dates expressed herein.

No reference herein to the Indenture and no provision of this Security or the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of (and premium, if any) and interest on this Security at the times, places and rate, and in the coin or currency, herein prescribed.

The Securities of this series are issuable only in registered form, without coupons, in denominations of U.S. $1,000 and any integral multiple of U.S. $1,000 in excess thereof. As provided in the Indenture and subject to certain limitations therein set forth, Securities of this series are exchangeable for a like aggregate principal amount of Securities of this series and of like tenor and terms of a different authorized denomination, as requested by the Holder surrendering the same.

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