In computing “Fixed Charges,” “Dividends on Preferred and Preference Stock of Subsidiaries” represent the before tax earnings necessary to pay such dividends, computed at the effective tax rates for the applicable periods.

DESCRIPTION OF THE SERIES 2009B SENIOR NOTES
 
 
Set forth below is a description of the specific terms of the Series 2009B Floating Rate Senior Notes due          ,     (the “Series 2009B Senior Notes”). This description supplements, and should be read together with, the description of the general terms and provisions of the senior notes set forth in the accompanying Prospectus under the caption “Description of the Senior Notes.” The following description does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the description in the accompanying Prospectus and the Senior Note Indenture dated as of January 1, 2007, as supplemented (the “Senior Note Indenture”), between the Company and Wells Fargo Bank, National Association, as trustee (the “Senior Note Indenture Trustee”).
 
General
 
The Series 2009B Senior Notes will be issued as a series of senior notes under the Senior Note Indenture. The Series 2009B Senior Notes will initially be issued in the aggregate principal amount of $          . The Company may, at any time and without the consent of the holders of the Series 2009B Senior Notes, issue additional notes having the same ranking and the same interest rate, maturity and other terms as the Series 2009B Senior Notes (except for the public offering price and issue date and the initial interest accrual date and initial Interest Payment Date (as defined below), if applicable). Any additional notes having such similar terms, together with the Series 2009B Senior Notes, will constitute a single series of senior notes under the Senior Note Indenture.
 
The entire principal amount of the Series 2009B Senior Notes will mature and become due and payable, together with any accrued and unpaid interest thereon, on          ,     . The Series 2009B Senior Notes are not subject to any sinking fund provision. The Series 2009B Senior Notes are available for purchase in denominations of $1,000 and any integral multiple thereof.
 
Interest
 
Each Series 2009B Senior Note shall bear interest from the date of original issuance, payable quarterly in arrears on the     day of     ,     ,      and      (each, an “Interest Payment Date”) to the person in whose name such Series 2009B Senior Note is registered at the close of business on the fifteenth calendar day prior to such payment date, whether or not a Business Day. However, interest payable on the maturity date of a Series 2009B Senior Note will be paid to the same person to whom the principal is payable. The initial Interest Payment Date is          , 2010. The amount of interest payable will be computed on the basis of the actual number of days elapsed over a 360-day year. If any Interest Payment Date (other than the maturity date) would otherwise be a day that is not a Business Day, the Interest Payment Date will be the next succeeding Business Day. If the maturity date is not a Business Day, the principal and interest due on that date will be payable on the next succeeding Business Day, and no interest shall accrue for the intervening period.
 
The Series 2009B Senior Notes will bear interest for each quarterly Interest Period at a per annum rate determined by the Calculation Agent, subject to the maximum interest rate permitted by New York or other applicable state law, as such law may be modified by United States law of general application. The interest rate applicable during each quarterly Interest Period will be equal to LIBOR on the Interest Determination Date for such Interest Period plus    %. Promptly upon such determination, the Calculation Agent will notify the Company and the Senior Note Indenture Trustee, if the Senior Note Indenture Trustee is not then serving as the Calculation Agent, of the interest rate for the new Interest Period. The interest rate determined by the Calculation Agent, absent manifest error, shall be binding and conclusive upon the beneficial owners and holders of the Series 2009B Senior Notes, the Company and the Senior Note Indenture Trustee.
 
Upon the request of a holder of the Series 2009B Senior Notes, the Calculation Agent will provide to such holder the interest rate in effect on the date of such request and, if determined, the interest rate for the next Interest Period.
 
The accrued interest for any period is calculated by multiplying the principal amount of a Series 2009B Senior Note by an accrued interest factor. The accrued interest factor is computed by adding the interest factor

Table of Contents

calculated for each day in the period for which accrued interest is being calculated. The interest factor (expressed as a decimal rounded upwards if necessary) is computed by dividing the interest rate (expressed as a decimal rounded upwards if necessary) applicable to such date by 360.
 
All percentages resulting from any calculation of the interest rate on the Series 2009B Senior Notes will be rounded, if necessary, to the nearest one-hundred thousandth of a percentage point, with five one-millionths of a percentage point rounded upwards (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655) and 9.876544% (or .09876544) being rounded to 9.87654% (or .0987654)), and all dollar amounts used in or resulting from such calculation will be rounded to the nearest cent (with one-half cent being rounded upwards).
 
Certain Definitions
 
The following definitions apply to the Series 2009B Senior Notes.
 
“Business Day” means a day other than (i) a Saturday or Sunday, (ii)  a day on which banks in New York, New York are authorized or obligated by law or executive order to remain closed, or (iii) a day on which the Senior Note Indenture Trustee’s corporate trust office is closed for business.
 
“Calculation Agent” means Wells Fargo Bank, National Association, or its successor appointed by the Company, acting as calculation agent.
 
“Interest Determination Date” means the second London Business Day immediately preceding the first day of the relevant Interest Period.
 
“Interest Period” means the period commencing on an Interest Payment Date for the Series 2009B Senior Notes (or, with respect to the initial Interest Period only, commencing on the issue date for the Series 2009B Senior Notes) and ending on the day before the next succeeding Interest Payment Date for the Series 2009B Senior Notes.
 
“LIBOR” means, with respect to any Interest Period, the rate (expressed as a percentage per annum) for deposits in U.S. dollars for a three-month period commencing on the first day of that Interest Period and ending on the next Interest Payment Date that appears on Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the Interest Determination Date for that Interest Period. If such rate does not appear on the Reuters LIBOR01 Page as of 11:00 a.m. (London time) on the Interest Determination Date for that Interest Period, LIBOR will be determined on the basis of the rates at which deposits in U.S. dollars for the Interest Period and in a principal amount of not less than $1,000,000 are offered to prime banks in the London interbank market by four major banks in the London interbank market, which may include affiliates of one or more of the Underwriters (as defined below), selected by the Calculation Agent (after consultation with the Company), at approximately 11:00 a.m., London time, on the Interest Determination Date for that Interest Period. The Calculation Agent will request the principal London office of each such bank to provide a quotation of its rate. If at least two such quotations are provided, LIBOR with respect to that Interest Period will be the arithmetic mean of such quotations. If fewer than two quotations are provided, LIBOR with respect to that Interest Period will be the arithmetic mean of the rates quoted by three major banks in New York City, which may include affiliates of one or more of the Underwriters, selected by the Calculation Agent (after consultation with the Company), at approximately 11:00 a.m., New York City time, on the first day of that Interest Period for loans in U.S. dollars to leading European banks for that Interest Period and in a principal amount of not less than $1,000,000. However, if fewer than three banks selected by the Calculation Agent to provide quotations are quoting as described above, LIBOR for that Interest Period will be the same as LIBOR as determined for the previous Interest Period. The establishment of LIBOR by the Calculation Agent shall (in the absence of manifest error) be final and binding. The Company will pay the principal of the Series 2009B Senior Notes and interest payable at maturity in immediately available funds at the corporate trust offices of Wells Fargo Bank, National Association, as Paying Agent.
 
“London Business Day” means a day that is a Business Day and a day on which dealings in deposits in U.S. dollars are transacted, or with respect to any future date are expected to be transacted, in the London interbank market.

“Reuters LIBOR01 Page” means the display designated as Reuters LIBOR01 on the Reuters 3000 Xtra (or such other page as may replace the Reuters LIBOR01 Page on that service, or such other service as may be nominated as the information vendor, for the purpose of displaying rates or prices comparable to the London Interbank Offered rate for U.S. dollar deposits).
 
Ranking
 
The Series 2009B Senior Notes will be direct, unsecured and unsubordinated obligations of the Company ranking equally with all other unsecured and unsubordinated obligations of the Company. Since the Company is a holding company, the right of the Company and, hence, the right of creditors of the Company (including holders of the Series 2009B Senior Notes) to participate in any distribution of the assets of any subsidiary of the Company, whether upon liquidation, reorganization or otherwise, is subject to prior claims of creditors of each subsidiary. The Series 2009B Senior Notes will be effectively subordinated to all secured debt of the Company. The Company had no secured debt outstanding at June 30, 2009. The Senior Note Indenture contains no restrictions on the amount of additional indebtedness that may be incurred by the Company.
 
Redemption
 
The Series 2009B Senior Notes will not be redeemable at the option of the Company prior to maturity.
 
Book-Entry Only Issuance — The Depository Trust Company
 
The Depository Trust Company (“DTC”) will act as the initial securities depositary for the Series 2009B Senior Notes. The Series 2009B Senior Notes will be issued only as fully-registered securities registered in the name of Cede & Co., DTC’s partnership nominee, or such other name as may be requested by an authorized representative of DTC. One or more fully-registered global Series 2009B Senior Notes certificates will be issued, representing in the aggregate the total principal amount of Series 2009B Senior Notes, and will be deposited with the Senior Note Indenture Trustee on behalf of DTC.
 
DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Securities Exchange Act of 1934, as amended. DTC holds and provides asset servicing for over 3.5 million issues of U.S. and non-U.S. equity issues, corporate and municipal debt issues and money market instruments from over 100 countries that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). DTC has Standard & Poor’s, a division of The McGraw Hill Companies, Inc., highest rating: AAA. The DTC rules applicable to its Direct and Indirect Participants are on file with the Securities and Exchange Commission. More information about DTC can be found at www.dtcc.com and www.dtc.org. The contents of such websites do not constitute part of this Prospectus Supplement.
 
Purchases of Series 2009B Senior Notes under the DTC system must be made by or through Direct Participants, which will receive a credit for the Series 2009B Senior Notes on DTC’s records. The ownership interest of each actual purchaser of each Series 2009B Senior Note (“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written


S-7


Table of Contents

confirmation from DTC of their purchases. Beneficial Owners are, however, expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings, from the Direct or Indirect Participants through which the Beneficial Owners purchased Series 2009B Senior Notes. Transfers of ownership interests in the Series 2009B Senior Notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in Series 2009B Senior Notes, except in the event that use of the book-entry system for the Series 2009B Senior Notes is discontinued.
 
To facilitate subsequent transfers, all Series 2009B Senior Notes deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of Series 2009B Senior Notes with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any changes in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Series 2009B Senior Notes. DTC’s records reflect only the identity of the Direct Participants to whose accounts such Series 2009B Senior Notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.
 
Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.
 
Although voting with respect to the Series 2009B Senior Notes is limited, in those cases where a vote is required, neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to Series 2009B Senior Notes unless authorized by a Direct Participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an Omnibus Proxy to the Company as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts Series 2009B Senior Notes are credited on the record date (identified in a listing attached to the Omnibus Proxy).
 
Payments on the Series 2009B Senior Notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from the Company or the Senior Note Indenture Trustee on the relevant payment date in accordance with their respective holdings shown on DTC’s records. Payments by Direct or Indirect Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers registered in “street name,” and will be the responsibility of such Direct or Indirect Participant and not of DTC or the Company, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is the responsibility of the Company, disbursement of such payments to Direct Participants is the responsibility of DTC, and disbursement of such payments to the Beneficial Owners is the responsibility of Direct and Indirect Participants.
 
Except as provided herein, a Beneficial Owner of a global Series 2009B Senior Note will not be entitled to receive physical delivery of Series 2009B Senior Notes. Accordingly, each Beneficial Owner must rely on the procedures of DTC to exercise any rights under the Series 2009B Senior Notes. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global Series 2009B Senior Note.
 
DTC may discontinue providing its services as securities depositary with respect to the Series 2009B Senior Notes at any time by giving reasonable notice to the Company. Under such circumstances, in the event that a successor securities depositary is not obtained, Series 2009B Senior Notes certificates will be printed and delivered to the holders of record. Additionally, the Company may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depositary) with respect to the Series 2009B Senior Notes. In that event, certificates for the Series 2009B Senior Notes will be printed and delivered to the holders of record. The Company understands, however, that under current industry practices, DTC would notify its Direct and Indirect Participants of the Company’s decision, but will only withdraw beneficial

interests from a global Series 2009B Senior Note at the request of each Direct or Indirect Participant. In that event, certificates for the Series 2009B Senior Notes will be printed and delivered to the applicable Direct or Indirect Participant.
 
The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that the Company believes to be reliable, but neither the Company nor any Underwriter takes any responsibility for the accuracy thereof. Neither the Company nor any Underwriter has any responsibility for the performance by DTC or its Direct or Indirect Participants of their respective obligations as described herein or under the rules and procedures governing their respective operations.

The Series 2009B Senior Notes will not be listed on any securities exchange or on any automated dealer quotation system.

This agreement does not apply to issuances of commercial paper or other debt securities with scheduled maturities of less than one year.
 
In order to facilitate the offering of the Series 2009B Senior Notes, the Underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Series 2009B Senior Notes. Specifically, the Underwriters may over-allot in connection with the offering, creating short positions in the Series 2009B Senior Notes for their own accounts. In addition, to cover over-allotments or to stabilize the price of the Series 2009B Senior Notes, the Underwriters may bid for, and purchase, Series 2009B Senior Notes in the open market. The Underwriters may reclaim selling concessions allowed to the Underwriters or dealers for distributing Series 2009B Senior Notes in the offering, if the Underwriters repurchase previously

distributed Series 2009B Senior Notes in transactions to cover short positions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the Series 2009B Senior Notes above independent market levels. The Underwriters are not required to engage in these activities, and may end any of these activities at any time without notice.
 
In general, purchases of a security for the purpose of stabilization or to reduce a short position could cause the price of the security to be higher than it might be in the absence of such purchases. The imposition of a penalty bid might also have an effect on the price of a security to the extent that it were to discourage resales of the security.
 
Neither the Company nor any Underwriter makes any representation or prediction as to the direction or magnitude of any effect that the transactions described above may have on the price of the Series 2009B Senior Notes. In addition, neither the Company nor any Underwriter makes any representation that the Underwriters will engage in such transactions or that such transactions once commenced will not be discontinued without notice.
 
The Underwriters and their affiliates have engaged in and may in the future engage in transactions with, and, from time to time, have performed commercial banking, investment banking and advisory services for, the Company and its affiliates in the ordinary course of business, for which they have received and will receive customary compensation.

CERTAIN RATIOS
 
The following table sets forth the Ratios of Earnings to Fixed Charges for the periods indicated.

Ratio of Earnings to Fixed Charges(2)
    3.86       3.65       3.46       3.49       3.49       1.93          
 
(1)  Due to seasonal variations in the demand for energy, operating results for the three months ended March 31, 2009 do not necessarily indicate operating results for the entire year.
 
(2)  This ratio is computed as follows: (i) “Earnings” have been calculated by adding to “Earnings Before Income Taxes” “Interest expense, net of amounts capitalized,” “Distributions on mandatorily redeemable preferred securities” and the debt portion of allowance for funds used during construction, less “Dividends on Preferred and Preference Stock of Subsidiaries;” and (ii) “Fixed Charges” consist of “Interest expense, net of amounts capitalized,” “Dividends on Preferred and Preference Stock of Subsidiaries,” “Distributions on mandatorily redeemable preferred securities” and the debt portion of allowance for funds used during construction. In computing “Fixed Charges,” “Dividends on Preferred and Preference Stock of Subsidiaries” represent the before tax earnings necessary to pay such dividends, computed at the effective tax rates for the applicable periods.
 
USE OF PROCEEDS
 
Except as may be otherwise described in an applicable Prospectus Supplement, the net proceeds received by the Company from the sale of the Common Stock, the Senior Notes or the Junior Subordinated Notes will be used to pay scheduled maturities and/or refundings of its securities, to repay short-term indebtedness to the extent outstanding and for other general corporate purposes.

Table of Contents

dated as of January 1, 2007, between the Company and Wells Fargo Bank, National Association, as trustee (the “Senior Note Indenture Trustee”), as to be supplemented by a supplemental indenture to the Senior Note Indenture establishing the Senior Notes of each series (the Senior Note Indenture, as so supplemented, is referred to as the “Senior Note Indenture”), the forms of which are filed as exhibits to the Registration Statement of which this Prospectus forms a part. The terms of the Senior Notes will include those stated in the Senior Note Indenture and those made a part of the Senior Note Indenture by reference to the Trust Indenture Act of 1939, as amended (the “1939 Act”). Certain capitalized terms used in this Prospectus are defined in the Senior Note Indenture.
 
General
 
The Senior Notes will be issued as unsecured senior debt securities under the Senior Note Indenture and will rank equally with all other unsecured and unsubordinated debt of the Company. The Senior Notes will be effectively subordinated to all secured debt of the Company. The Company had no secured debt outstanding at March 31, 2009. Since the Company is a holding company, the right of the Company and, hence, the right of creditors of the Company (including holders of Senior Notes) to participate in any distribution of the assets of any subsidiary of the Company, whether upon liquidation, reorganization or otherwise, is subject to prior claims of creditors and preferred and preference stockholders of each subsidiary. The Senior Note Indenture does not limit the aggregate principal amount of Senior Notes that may be issued under the Senior Note Indenture and provides that Senior Notes may be issued from time to time in one or more series pursuant to an indenture supplemental to the Senior Note Indenture. The Senior Note Indenture gives the Company the ability to reopen a previous issue of Senior Notes and issue additional Senior Notes of such series, unless otherwise provided.
 
Reference is made to the Prospectus Supplement that will accompany this Prospectus for the following terms of the series of Senior Notes being offered by such Prospectus Supplement: (i) the title of such Senior Notes; (ii) any limit on the aggregate principal amount of such Senior Notes; (iii) the date or dates on which the principal of such Senior Notes is payable; (iv) the rate or rates at which such Senior Notes shall bear interest, if any, or any method by which such rate or rates will be determined, the date or dates from which such interest will accrue, the interest payment dates on which such interest shall be payable, and the regular record date for the interest payable on any interest payment date; (v) the place or places where the principal of (and premium, if any) and interest, if any, on such Senior Notes shall be payable; (vi) the period or periods within which, the price or prices at which and the terms and conditions on which such Senior Notes may be redeemed, in whole or in part, at the option of the Company or at the option of the holder prior to their maturity; (vii) the obligation, if any, of the Company to redeem or purchase such Senior Notes; (viii) the date or dates, if any, after which such Senior Notes may be converted or exchanged at the option of the holder into or for shares of Common Stock of the Company and the terms for any such conversion or exchange; (ix) the denominations in which such Senior Notes shall be issuable; (x) if other than the principal amount of such Senior Notes, the portion of the principal amount of such Senior Notes which shall be payable upon declaration of acceleration of the maturity of such Senior Notes; (xi) any deletions from, modifications of or additions to the Events of Default or covenants of the Company as provided in the Senior Note Indenture pertaining to such Senior Notes; (xii) whether such Senior Notes shall be issued in whole or in part in the form of a Global Security; and (xiii) any other terms of such Senior Notes.
 
The Senior Note Indenture does not contain provisions that afford holders of Senior Notes protection in the event of a highly leveraged transaction involving the Company.
 
Events of Default
 
The Senior Note Indenture provides that any one or more of the following described events with respect to the Senior Notes of any series, which has occurred and is continuing, constitutes an “Event of Default” with respect to the Senior Notes of such series:
 
(a) failure for 30 days to pay interest on the Senior Notes of such series, when due on an interest payment date other than at maturity or upon earlier redemption; or
 
(b) failure to pay principal or premium, if any, or interest on the Senior Notes of such series when due at maturity or upon earlier redemption; or

Table of Contents

(c) failure for three Business Days to deposit any sinking fund payment when due by the terms of a Senior Note of such series; or
 
(d) failure to observe or perform any other covenant or warranty of the Company in the Senior Note Indenture (other than a covenant or warranty which has expressly been included in the Senior Note Indenture solely for the benefit of one or more series of Senior Notes other than such series) for 90 days after written notice to the Company from the Senior Note Indenture Trustee or the holders of at least 25% in principal amount of the outstanding Senior Notes of such series; or
 
(e) certain events of bankruptcy, insolvency or reorganization of the Company.
 
The holders of not less than a majority in aggregate outstanding principal amount of the Senior Notes of any series have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Senior Note Indenture Trustee with respect to the Senior Notes of such series. If a Senior Note Indenture Event of Default occurs and is continuing with respect to the Senior Notes of any series, then the Senior Note Indenture Trustee or the holders of not less than 25% in aggregate outstanding principal amount of the Senior Notes of such series may declare the principal amount of the Senior Notes due and payable immediately by notice in writing to the Company (and to the Senior Note Indenture Trustee if given by the holders), and upon any such declaration such principal amount shall become immediately due and payable. At any time after such a declaration of acceleration with respect to the Senior Notes of any series has been made and before a judgment or decree for payment of the money due has been obtained as provided in Article Five of the Senior Note Indenture, the holders of not less than a majority in aggregate outstanding principal amount of the Senior Notes of such series may rescind and annul such declaration and its consequences if the default has been cured or waived and the Company has paid or deposited with the Senior Note Indenture Trustee a sum sufficient to pay all matured installments of interest and principal due otherwise than by acceleration and all sums paid or advanced by the Senior Note Indenture Trustee, including reasonable compensation and expenses of the Senior Note Indenture Trustee.
 
The holders of not less than a majority in aggregate outstanding principal amount of the Senior Notes of any series may, on behalf of the holders of all the Senior Notes of such series, waive any past default with respect to such series, except (i) a default in the payment of principal or interest or (ii) a default in respect of a covenant or provision which under Article Nine of the Senior Note Indenture cannot be modified or amended without the consent of the holder of each outstanding Senior Note of such series affected.
 
Registration and Transfer
 
The Company shall not be required to (i) issue, register the transfer of or exchange Senior Notes of any series during a period of 15 days immediately preceding the date notice is given identifying the Senior Notes of such series called for redemption or (ii) issue, register the transfer of or exchange any Senior Notes so selected for redemption, in whole or in part, except the unredeemed portion of any Senior Note being redeemed in part.
 
Payment and Paying Agent
 
Unless otherwise indicated in an applicable Prospectus Supplement, payment of principal of any Senior Notes will be made only against surrender to the Paying Agent of such Senior Notes. Principal of and interest on Senior Notes will be payable, subject to any applicable laws and regulations, at the office of such Paying Agent or Paying Agents as the Company may designate from time to time, except that, at the option of the Company, payment of any interest may be made by wire transfer or other electronic transfer or by check mailed to the address of the person entitled to an interest payment as such address shall appear in the Security Register with respect to the Senior Notes. Payment of interest on Senior Notes on any interest payment date will be made to the person in whose name the Senior Notes (or predecessor security) are registered at the close of business on the record date for such interest payment.
 
Unless otherwise indicated in an applicable Prospectus Supplement, the Senior Note Indenture Trustee will act as Paying Agent with respect to the Senior Notes. The Company may at any time designate additional Paying Agents or rescind the designation of any Paying Agents or approve a change in the office through which any Paying Agent acts.

Table of Contents

All moneys paid by the Company to a Paying Agent for the payment of the principal of or interest on the Senior Notes of any series which remain unclaimed at the end of two years after such principal or interest shall have become due and payable will be repaid to the Company, and the holder of such Senior Notes will from that time forward look only to the Company for payment of such principal and interest.
 
Modification
 
The Senior Note Indenture contains provisions permitting the Company and the Senior Note Indenture Trustee, with the consent of the holders of not less than a majority in principal amount of the outstanding Senior Notes of each series that is affected, to modify the Senior Note Indenture or the rights of the holders of the Senior Notes of such series; provided, that no such modification may, without the consent of the holder of each outstanding Senior Note that is affected, (i) change the stated maturity of the principal of, or any installment of principal of or interest on, any Senior Note, or reduce the principal amount of any Senior Note or the rate of interest on any Senior Note or any premium payable upon the redemption of any Senior Note, or change the method of calculating the rate of interest of any Senior Note, or impair the right to institute suit for the enforcement of any such payment on or after the stated maturity of any Senior Note (or, in the case of redemption, on or after the redemption date), or (ii) reduce the percentage of principal amount of the outstanding Senior Notes of any series, the consent of whose holders is required for any such supplemental indenture, or the consent of whose holders is required for any waiver (of compliance with certain provisions of the Senior Note Indenture or certain defaults under the Senior Note Indenture and their consequences) provided for in the Senior Note Indenture, or (iii) modify any of the provisions of the Senior Note Indenture relating to supplemental indentures, waiver of past defaults or waiver of certain covenants, except to increase any such percentage or to provide that certain other provisions of the Senior Note Indenture cannot be modified or waived without the consent of the holder of each outstanding Senior Note that is affected.

Information Concerning the Senior Note Indenture Trustee
 
The Senior Note Indenture Trustee, prior to an Event of Default with respect to Senior Notes of any series, undertakes to perform, with respect to Senior Notes of such series, only such duties as are specifically set forth in the Senior Note Indenture and, in case an Event of Default with respect to Senior Notes of any series has occurred and is continuing, shall exercise, with respect to Senior Notes of such series, the same degree of care as a prudent individual would exercise in the conduct of his or her own affairs. Subject to such provision, the Senior Note Indenture Trustee is under no obligation to exercise any of the powers vested in it by the Senior Note Indenture at the request of any holder of Senior Notes of any series, unless offered reasonable indemnity by such holder against the costs, expenses and liabilities which might be incurred by the Senior Note Indenture Trustee.

The term “Senior Indebtedness” means, with respect to the Company, (i) any payment due in respect of indebtedness of the Company, whether outstanding at the date of execution of the Subordinated Note Indenture or incurred, created or assumed after such date, (a) in respect of money borrowed (including any financial derivative, hedging or futures contract or similar instrument) and (b) evidenced by securities, debentures, bonds, notes or other similar instruments issued by the Company that, by their terms, are senior or senior subordinated debt securities including, without limitation, all such obligations under its indentures with various trustees; (ii) all capital lease obligations; (iii) all obligations issued or assumed as the deferred purchase price of property, all conditional sale obligations and all obligations of the Company under any title retention agreement (but excluding trade accounts payable arising in the ordinary course of business and long-term purchase obligations); (iv) all obligations for the reimbursement of any letter of credit, banker’s acceptance, security purchase facility or similar credit transaction; (v) all obligations of the type referred to in clauses (i) through (iv) above of other persons the payment of which the Company is responsible or liable as obligor, guarantor or otherwise; and (vi) all obligations of the type referred to in clauses (i) through (v) above of other persons secured by any lien on any property or asset of the Company (whether or not such obligation is assumed by the Company), except for (1) any such indebtedness that is by its terms subordinated to or that ranks equally with the Junior Subordinated Notes and (2) any unsecured indebtedness between or among the Company or its affiliates. Such Senior Indebtedness shall continue to be Senior Indebtedness and be entitled to the benefits of the subordination provisions contained in the Subordinated Note Indenture irrespective of any amendment, modification or waiver of any term of such Senior Indebtedness.
 
The Subordinated Note Indenture does not limit the aggregate amount of Senior Indebtedness that may be issued by the Company. As of March 31, 2009, Senior Indebtedness of the Company aggregated approximately $1,798,000,000. Since the Company is a holding company, the right of the Company and, hence, the right of creditors of the Company (including holders of Senior Notes and Junior Subordinated Notes) to participate in any

distribution of the assets of any subsidiary of the Company, whether upon liquidation, reorganization or otherwise, is subject to prior claims of creditors and preferred and preferences stockholders of each subsidiary.
 
Additional Interest
 
“Additional Interest” is defined in the Subordinated Note Indenture as any interest due and not paid on an interest payment date, together with interest on such interest due from such interest payment date to the date of payment, compounded quarterly, on each interest payment date.
 
Certain Covenants
 
The Company covenants in the Subordinated Note Indenture, for the benefit of the holders of each series of Junior Subordinated Notes, that, if at such time the Company shall have given notice of its election to extend an interest payment period for such series of Junior Subordinated Notes and such extension shall be continuing, or if at such time an Event of Default under the Subordinated Note Indenture with respect to such series of Junior Subordinated Notes shall have occurred and be continuing, (a) the Company shall not declare or pay any dividend or make any distributions with respect to, or redeem, purchase, acquire or make a liquidation payment with respect to, any of its capital stock, and (b) the Company shall not make any payment of interest, principal or premium, if any, on or repay, repurchase or redeem any debt securities (including guarantees) issued by the Company which rank equally with or junior to the Junior Subordinated Notes. None of the foregoing, however, shall restrict (i) any of the actions described in the preceding sentence resulting from any reclassification of the Company’s capital stock or the exchange or conversion of one class or series of the Company’s capital stock for another class or series of the Company’s capital stock, (ii) the purchase of fractional interests in shares of the Company’s capital stock pursuant to the conversion or exchange provisions of such capital stock or the security being converted or exchanged, (iii) dividends, payments or distributions payable in shares of capital stock, (iv) redemptions, purchases or other acquisitions of shares of capital stock in connection with any employment contract, incentive plan, benefit plan or other similar arrangement of the Company or any of its subsidiaries or in connection with a dividend reinvestment or stock purchase plan, or (v) any declaration of a dividend in connection with implementation of any stockholders’ rights plan, or the issuance of rights, stock or other property under any such plan, or the redemption, repurchase or other acquisition of any such rights pursuant thereto.
 
Events of Default
 
The Subordinated Note Indenture provides that any one or more of the following described events with respect to the Junior Subordinated Notes of any series, which has occurred and is continuing, constitutes an “Event of Default” with respect to the Junior Subordinated Notes of such series:
 
(a) failure for 30 days to pay interest on the Junior Subordinated Notes of such series, including any Additional Interest on such unpaid interest, when due on an interest payment date other than at maturity or upon earlier redemption; provided, however, that a valid extension of the interest payment period by the Company shall not constitute a default in the payment of interest for this purpose; or
 
(b) failure to pay principal or premium, if any, or interest, including Additional Interest, on the Junior Subordinated Notes of such series when due at maturity or upon earlier redemption; or
 
(c) failure for three Business Days to deposit any sinking fund payment when due by the terms of a Junior Subordinated Note of such series; or
 
(d) failure to observe or perform any other covenant or warranty of the Company in the Subordinated Note Indenture (other than a covenant or warranty which has expressly been included in the Subordinated Note Indenture solely for the benefit of one or more series of Junior Subordinated Notes other than such series) for 90 days after written notice to the Company from the Subordinated Note Indenture Trustee or the holders of at least 25% in principal amount of the outstanding Junior Subordinated Notes of such series; or
 
(e) certain events of bankruptcy, insolvency or reorganization of the Company.

If a Subordinated Note Indenture Event of Default occurs and is continuing with respect to the Junior Subordinated Notes of any series, then the Subordinated Note Indenture Trustee or the holders of not less than 25% in aggregate outstanding principal amount of the Junior Subordinated Notes of such series may declare the principal amount of the Junior Subordinated Notes due and payable immediately by notice in writing to the Company (and to the Subordinated Note Indenture Trustee if given by the holders), and upon any such declaration such principal amount shall become immediately due and payable. At any time after such a declaration of acceleration with respect to the Junior Subordinated Notes of any series has been made and before a judgment or decree for payment of the money due has been obtained as provided in Article Five of the Subordinated Note Indenture, the holders of not less than a majority in aggregate outstanding principal amount of the Junior Subordinated Notes of such series may rescind and annul such declaration and its consequences if the default has been cured or waived and the Company has paid or deposited with the Subordinated Note Indenture Trustee a sum sufficient to pay all matured installments of interest (including any Additional Interest) and principal due otherwise than by acceleration and all sums paid or advanced by the Subordinated Note Indenture Trustee, including reasonable compensation and expenses of the Subordinated Note Indenture Trustee.
 
The holders of not less than a majority in aggregate outstanding principal amount of the Junior Subordinated Notes of any series may, on behalf of the holders of all the Junior Subordinated Notes of such series, waive any past default with respect to such series, except (i) a default in the payment of principal or interest or (ii) a default in respect of a covenant or provision which under Article Nine of the Subordinated Note Indenture cannot be modified or amended without the consent of the holder of each outstanding Junior Subordinated Note of such series affected.
