PROSPECTUS SUMMARY

This summary highlights information contained elsewhere in this prospectus. This summary may not contain all of the information that may be important to you. You should read the entire prospectus carefully before making a decision to invest in our senior debentures.

Our Company

We are a regulated utility serving customers in Iowa, Minnesota and Illinois. We are engaged principally in the generation, transmission, distribution and sale of electric energy; the purchase, distribution, transportation and sale of natural gas; and the delivery of steam services in selected markets. As of December 31, 2002, we served approximately 526,000 electric customers in 760 communities and approximately 235,000 gas customers in 253 communities. All of our common stock is owned by Alliant Energy Corporation, an energy-services provider engaged primarily in regulated utility operations in the Midwest, including through our company, and with other non-regulated domestic and international operations.

We are subject to the jurisdiction of the Iowa Utilities Board, or IUB, the Minnesota Public Utilities Commission, or MPUC, and the Illinois Commerce Commission, or ICC, with respect to various portions of our operations. We are also subject to the jurisdiction of the Federal Energy Regulatory Commission and the Nuclear Regulatory Commission, or NRC. Our parent company, Alliant Energy Corporation, is a registered public utility holding company subject to regulation by the Securities and Exchange Commission, or SEC, under the Public Utility Holding Company Act of 1935. We are also subject to some requirements of that Act.

Rate Case Developments

Iowa Electric Rate Case Final Order

On April 15, 2003, we received the final order in our retail electric rate case from the IUB. The IUB granted a $26 million, or 2.91%, annual revenue increase and authorized a return on common equity of 11.15% effective May 28, 2003. The compliance tarriffs were effective on August 22, 2003. Since the final increase approved by the IUB is lower than the $17 million interim relief granted in October 2002, a refund plan was filed with the IUB in July 2003. We are reserving all amounts related to the anticipated refund.

Iowa Gas Rate Case Final Order

On May 15, 2003, we received the final order in our retail gas rate case from the IUB. The IUB granted a $13 million, or 4.8%, annual revenue increase and authorized a return on common equity of 11.05%. We expect this final order to be effective in August 2003.

Minnesota Electric Rate Case

On May 19, 2003, we filed a rate request with the MPUC for approval to increase electric base rates by approximately $5.0 million, or 8.0%, with a rate of return on common equity of 12.3%. On July 18, 2003, the MPUC granted us approval to increase rates on an interim basis by approximately $1.9 million, or 3.1%, which is approximately 66% of the $2.9 million of interim relief requested. The rate of return on common equity was set at 11.0%. The interim rates became effective on July 18, 2003. We expect final rates to be effective in April 2004.

Credit Facility Borrowings and Availability

The following table sets forth our bank credit facility borrowing and availability as of July 31, 2003:

Total facility........................       $200,000,000
Borrowing backed by facility..........         38,000,000
                                          ----------------
Availability..........................       $162,000,000
                                          ================

Our bank credit facility expires in October 2003. While we anticipate renewing the credit facility in the third quarter of 2003, we cannot provide complete assurance that we will be able to do so.

                                                         will not be revised downward or withdrawn by the ratings
                                                         agencies.

                                                         accrued interest on that principal amount to the redemption
                                                         date and the make-whole amount, if any, with respect to

Covenants............................................    The indenture governing the senior debentures contains
                                                         covenants that, among other things, limit our ability to:

                                                         o  create some types of secured indebtedness; and

                                                         o  consolidate or merge.

                                                         These covenants are subject to important exceptions and
                                                         qualifications, which are described under the heading
                                                         "Description of the Senior Debentures" in this prospectus.

No limitation on debt................................    The indenture governing the senior debentures does not
                                                         limit the amount of senior debentures that we may issue or
                                                         provide holders any protections should we be involved in a
                                                         highly leveraged transaction.

Use of proceeds......................................    We estimate that the net proceeds from the offering will be
                                                         approximately $99.0 million. We intend to use the proceeds
                                                         from this offering to repay long-term debt.

Denomination.........................................    The senior debentures will be issued in integral multiples
                                                         of $1,000.

Absence of market for the senior debentures..........    The senior debentures are a new issue of securities with no
                                                         established trading market. We currently have no intention
                                                         to apply to list the senior debenture on any securities
                                                         exchange or to seek their admission to trading on any
                                                         automated quotation system. Accordingly, we cannot provide
                                                         any assurance as to the development or liquidity of any
                                                         market for the senior debentures. See "Underwriting."

THE COMPANY

We are a regulated utility serving customers in Iowa, Minnesota and Illinois. We are engaged principally in the generation, transmission, distribution and sale of electric energy; the purchase, distribution, transportation and sale of natural gas; and the delivery of steam services in selected markets. As of December 31, 2002, we served approximately 526,000 electric customers in 760 communities and approximately 235,000 gas customers in 253 communities. All of our common stock is owned by Alliant Energy Corporation, an energy-services provider engaged primarily in regulated utility operations in the Midwest, including through our company, and with other non-regulated domestic and international operations.

Competitive Strengths

We believe that our competitive strengths include the following:

Successful Rate Cases: We have recently received favorable outcomes from the rate cases we filed in Iowa. The IUB approved an annual electric rate increase of $26 million for us, an increase of 2.9% over current rates, and authorized a return on common equity of 11.15%. The IUB also approved an annual gas rate increase of $13 million for us, an increase of 4.8% over current rates, and authorized a return on common equity of 11.05%. In addition, on July 18, 2003, the MPUC granted us approval to increase rates in Minnesota on an interim basis by approximately $1.9 million, or 3.1%, and authorized a return on common equity of 11.0%.

Substantial Opportunities to Invest in Our Operations: The Iowa legislature passed a bill in 2001 to encourage construction of new generating facilities in Iowa through House File 577. This legislation eased siting requirements and gave the IUB authority to authorize upfront rate making principles for certain new generating facilities built in Iowa. We plan, subject to market conditions and favorable regulatory treatment, to develop up to 1,200 megawatts of new electric generation over the next 10 years. Currently, our Power Iowa plan includes adding approximately 550 megawatts of natural gas-fired generation by 2004; 100 megawatts of capacity generated from renewable energy sources by December 2003; researching options for an additional 500-600 megawatts of generation; and increases in energy efficiency through energy conservation and process improvements at various commercial and industrial customer locations. In January 2003, the IUB approved our siting certificate for an approximately 550-megawatt natural gas-fired plant in Clear Lake and construction began shortly thereafter. We will receive a regulatory rate of return of 12.23% on the equity component for 27.6 years with respect to this plant. This plant is scheduled to be in service prior to the 2004 summer peak.

Operate Our Transmission and Distribution Businesses to High Standards of Customer Service and Reliability. We have over 78 years of experience in operating and managing rate-regulated electric and gas transmission and distribution businesses and we use this experience to seek to achieve high standards of customer service and reliability in a cost-effective manner.

Strategy

Our strategic objectives are:

o To increase our megawatt capacity through investment in new electric power generation, subject to appropriate regulatory incentives;

o To increase plant availability and reduce the cost of energy production;

o To enhance service reliability and operational excellence;

o To maintain excellent customer service;

o To maintain favorable regulatory relationships;

o To remain current with cutting-edge technologies that impact our business;

o To practice proactive environmental compliance; and

o To continue to deliver strong operating results.

Operations

During 2002, we had total operating revenues of approximately $1,211.6 million, which included $964.9 million in electric revenues, or 80% of revenues, $214.9 million in gas revenues, or 18% of revenues, and $31.8 million in steam revenues, or 2% of revenues. No single customer accounted for more than 10% of our consolidated revenues in 2002. Our electric and gas revenues for 2002, sales for 2002 and customers as of December 31, 2002 consisted of the following:

Electric Operations. In 2002, we had a maximum peak hour demand of 3,097 megawatts in the month of July. During 2002, our sources of generation included 57% coal, 23% purchased-power, 18% nuclear and 2% gas/other.

As of December 31, 2002, we owned and operated 7,068 miles of electric transmission lines and 801 substation facilities connecting with its high voltage transmission systems. See "--Transmission Assets." A non-cancelable operating agreement, which extends through December 31, 2035, provides for the joint use of certain transmission facilities of ours and Central Iowa Power Cooperative.

Gas Operations. At December 31, 2002, we served approximately 235,000 customers. The gas utility operations accounted for 18% of our operating revenues for the year ended December 31, 2002.

Steam Operations. Steam operations in Cedar Rapids, Iowa, represented about 2% of our revenues for the year ended December 31, 2002.

Construction Program. Our construction expenditures for 2002 were approximately $248 million. Anticipated construction expenditures are approximately $450 million for 2003 (excluding approximately $109 million for the purchase of turbines and related equipment from affiliates and including $220 million for the Power Iowa plan), and $640 million for 2004 through 2005 (including $80 million for the Power Iowa plan).

Transmission Assets

In 2001, we and five other electric utilities filed an application with the Federal Energy Regulatory Commission to create TRANSLink Transmission Co. LLC, a for-profit, transmission-only company. In April 2002, the Federal Energy Regulatory Commission conditionally approved TRANSLink's formation and TRANSLink's participation in the Midwest Independent System Operator. In June 2002, TRANSLink Development Co. LLC was formed to oversee the start-up activities for TRANSLink. Since June 2002, six additional electric utilities joined TRANSLink. In June 2003, the IUB dismissed, without prejudice, our plan to contribute and transfer transmission

-7-

assets of 69 kilovolts and greater to TRANSLink. The IUB encouraged participating companies to revise and re-file their reorganization applications. We are currently evaluating our options with respect to TRANSLink.

Nuclear Management Company

We own a 70% interest in Duane Arnold Energy Center, a 580-megawatt (net capacity) nuclear plant, which is operated by the Nuclear Management Company, LLC under contract to us. The Duane Arnold operating license expires in 2014.

The Nuclear Management Company was formed in 1999 to consolidate the operation of its owners' nuclear plants and to provide similar capabilities for other nuclear operators and owners. Combined, the Nuclear Management Company operates eight nuclear generating units at six sites. Our parent, Alliant Energy Corporation, through its direct, non-utility subsidiary, Alliant Energy Nuclear LLC, owns 20% of Nuclear Management Company. Similar to others involved with the Nuclear Management Company, we continue to own our respective plant and are entitled to the energy generated at this plant. Each partner in the Nuclear Management Company retains the financial obligations for the safe operation, maintenance and the decommissioning of its plants.

Rates and Regulatory Environment

A significant portion of our operations are under the jurisdiction of the IUB. Requests for rate relief are based on historical test periods, adjusted for some known and measurable changes. Our retail tariffs provide for subsequent adjustments to our electric and natural gas rates for changes in the cost of fuel, purchased energy and natural gas purchased for resale. Purchased-power capacity costs are not recovered from electric customers through this energy adjustment clause mechanism. Recovery of these capacity costs must be addressed in formal rate proceedings.

We are also subject to regulation by the MPUC and the ICC with respect to our operations and our rates in Minnesota and Illinois, respectively.

We are currently addressing the recovery of our utility cost increases through several rate filings. Our recent rate cases are summarized as follows (dollars in millions):

(1) Since the final increase approved by the IUB is lower than the $17 million interim relief granted in October 2002, a refund plan was filed with the IUB in July 2003. We are reserving all amounts related to the anticipated refund.

The Federal Energy Regulatory Commission has jurisdiction under the Federal Power Act over some of our electric utility facilities and operations, wholesale rates and accounting practices, and in some other respects.

Our parent, Alliant Energy Corporation, operates as a registered public utility holding company subject to regulation by the SEC under the Public Utility Company Holding Act. As a result, we are subject to some of the regulatory provisions of the Public Utility Company Holding Act, including provisions relating to the issuance and sales of securities, acquisitions and sales of some utility properties and acquisition and retention of interests in non-utility businesses.

We are indirectly and directly subject to the jurisdiction of the NRC with respect to the Duane Arnold Energy Center and to the jurisdiction of the U.S. Department of Energy with respect to the disposal of nuclear fuel

and other radioactive wastes from such plants. The NRC has broad supervisory and regulatory jurisdiction over the construction and operation of nuclear reactors, particularly with regard to public health, safety and environmental considerations. The operation and design of nuclear power plants is under constant review by the NRC.

DESCRIPTION OF SENIOR DEBENTURES

We will issue the senior debentures as a separate series of securities under the indenture, dated as of August 20, 2003, between us and Bank One Trust Company, National Association, as trustee, or Bank One Trust.

This section summarizes the indenture. Since this is only a summary, it does not contain all of the information that may be important to you. The summary is subject to and qualified in its entirety by reference to the indenture which is filed as an exhibit to the registration statement of which this prospectus is a part and incorporated by reference into this prospectus. See "Where You Can Find More Information." Parenthetical section references under this heading are references to sections of the indenture.

General

The indenture does not limit the aggregate principal amount of senior unsecured debt securities that we can issue under it, and provides that we may issue securities from time to time in one or more series pursuant to the terms of one or more supplemental indentures, board resolutions or officers' certificates creating the series. The indenture also does not limit the total amount of debt that we can incur under other instrument, including first mortgage bonds. It also does not give holders of the senior debentures protection in the event we engage in a highly leveraged or other transaction that may adversely affect holders of the senior debentures. As of the date of this prospectus, we have no senior debentures outstanding under the indenture.

This section summarizes the indenture. Since this is only a summary, it does not contain all of the information that may be important to you. The summary is subject to and qualified in its entirety by reference to the indenture which is filed as an exhibit to the registration statement of which this prospectus is a part and incorporated by reference into this prospectus. See "Where You Can Find More Information." Parenthetical section references under this heading are references to sections of the indenture.

Maturity and Interest

We are offering the senior debentures in the aggregate principal amount of $100 million. The senior debentures will mature on __________, 2018. Each senior debenture will bear interest from __________, 2003, or from and including the most recent interest payment date to which we have paid interest, at the rate of ____% per year. We will pay interest twice per year, on ______ and ______, commencing __________, _____, to the persons in whose names the senior debentures are registered at the close of business (1) on the business day prior to each interest payment date if the senior debentures remain in book-entry only form or (2) on the fifteenth calendar day before each interest payment date if the senior debentures do not remain in book-entry only form.

Ranking

The senior debentures will be our senior, unsecured and unsubordinated obligations, ranking equally and ratably with all our other senior, unsecured and unsubordinated obligations. The senior debentures will be effectively subordinated to all of our existing and future secured indebtedness.

We currently have first mortgage bonds, collateral trust bonds and unsecured long-term debt outstanding. Substantially all of our tangible public utility property is subject to direct first mortgage liens under our indentures and deeds of trust securing our first mortgage bonds. Our indentures and deeds of trust securing our collateral trust bonds are direct second liens on a significant portion of of our tangible public utility property while some of our first mortgage bonds remain outstanding. If we become bankrupt, liquidate or reorganize, the trustees for the first mortgage bonds and collateral trust bonds could use the collateral property to satisfy our obligations under the first mortgage bonds and collateral trust bonds before holders of unsecured debt securities, including the senior debentures, would receive any payments.

As of June 30, 2003, giving pro forma effect to this offering and our use of the net proceeds, we would have had $119.0 million aggregate principal amount of first mortgage bonds, $234.4 million aggregate principal amount of collateral trust bonds and $483.3 million aggregate principal amount in unsecured long-term debt outstanding.

Redemption Prior to Maturity

We may redeem the senior debentures at any time at our option, in whole or in part, at a redemption price equal to the sum of the principal amount of the senior debentures we redeem, accrued interest on that principal amount to the redemption date and the make-whole amount, if any, with respect to those senior debentures. (Officers' Certificate). This sum is referred to as the redemption price.

"Make-whole amount" means, in connection with the optional redemption, the excess, if any, of:

o the aggregate present value as of the date of any optional redemption of each dollar of principal being redeemed and the amount of interest, exclusive of interest accrued to the date of redemption, that would have been payable in respect of such dollar of principal if such redemption had not been made, determined by discounting, on a semi-annual basis, such principal and interest at the reinvestment rate, as determined on the third business day preceding the date that notice of the redemption is given, from the respective dates on which such principal and interest would have been payable if such redemption had not been made, over

o the aggregate principal amount of the senior debentures being redeemed.

"Reinvestment rate" means ___% plus the arithmetic mean of the yields under the headings "Week Ending" published in the most recent statistical release under the caption "Treasury Constant Maturities" for the maturity, rounded to the nearest month, corresponding to the remaining life to maturity, as of the payment date of the principal being redeemed. If no maturity exactly corresponds to such maturity, yields for the two published maturities most closely corresponding to such maturity will be calculated pursuant to the immediately preceding sentence and the reinvestment rate will be interpolated or extrapolated from such yields on a straight-line basis, rounding in each of the relevant periods to the nearest month. For purposes of calculating the reinvestment rate, the most recent statistical release published prior to the date of determination of the make-whole amount will be used.

"Statistical release" means the statistical release designated "H.15(519)" or any successor publication which is published weekly by the Federal Reserve System and which establishes yields on actively traded United States government securities adjusted to constant maturities or, if such statistical release is not published at the time of any determination, then such other reasonably comparable index which shall be designated by us.

No sinking fund will be established for the benefit of the senior debentures.

Payments

We will pay principal of, and premium, if any, and interest on, the senior debentures at the office or agency we maintain for that purpose, initially the corporate trust office of the trustee. Bank One Trust is the initial paying agent designated for the senior debentures. We may designate additional paying agents, rescind the designation of any paying agent or approve a change in the office through which any paying agent acts, but we must maintain a paying agent in each place where payments on the senior debentures are payable. (Sections 301, 307 and 602).

Purchase and Cancellation

We may at any time purchase senior debentures in the open market or otherwise at any price, subject to applicable U.S. securities laws. Any senior debentures so purchased must be promptly surrendered to the trustee for cancellation. (Section 309).

-10-

Restrictive Covenants

Except as otherwise set forth under "-- Defeasance" below, for so long as any senior debentures remain outstanding or any amount remains unpaid on any of the senior debentures, we will comply with the terms of the covenants set forth below. If we issue additional series of securities under the indenture in the future, then those series may or may not have different covenants.

Limitations on Liens

The indenture provides generally that we will not, and we will not permit any of our subsidiaries to, create or allow to be created or to exist any lien on any of our properties or assets to secure any indebtedness, without making effective a provision that makes the senior debentures to which this limitation applies equally and ratably secured with or prior to all such indebtedness and with any other indebtedness that is also entitled to be equally secured. This restriction does not apply to or prevent the creation or existence of:

o liens securing our first mortgage bonds and collateral trust bonds issued under:

o our indenture and deed of trust, dated as of February 1, 1923, with Bank One Trust, as successor trustee, as amended and supplemented from time to time;

o our indenture of mortgage and deed of trust, dated as of August 1, 1940, with Bank One Trust, as successor trustee, as amended and supplemented from time to time;

o our indenture, dated as of January 1, 1948, with JPMorgan Chase Bank, as trustee, as amended and supplemented from time to time; and

o liens under our indenture of mortgage and deed of trust, dated as of September 1, 1993, with Bank One Trust, as successor trustee, as amended and supplemented from time to time;

o liens on property that existed when we acquired or constructed the property or were created within one year after that time;

o liens on property that secure payment of all or part of the purchase price or construction cost of the property, including the extension of any liens to repairs or improvements made on the property;

o the pledge of any bonds or other securities at any time issued under any of the liens permitted by the above-listed items;

o tax liens and other governmental charges which are not delinquent or which can be paid without penalty or which are being contested;

o liens incurred in the ordinary course of business for charges that are not delinquent or that are being contested, including mechanics', workmen's, repairmen's, materialmen's, warehousemen's and carriers' liens and liens securing workers' compensation and other employee awards;

o liens in respect of judgments or awards with respect to which we have the right to prosecute an appeal or other proceeding for review;

o easements, reservations, regulations and rights of others in, and defects of title in, some of our property;

o any defects or irregularities in title to any rights-of-way and/or to any real estate used or to be used for right-of-way purposes or held under lease, easement, license or similar right;

o liens securing indebtedness neither created, assumed nor guaranteed by us nor on account of which we customarily pay interest;

-11-

o some leasehold interests;

o any controls, restrictions, obligations or other burdens imposed by any law, rule or regulation of any governmental authority on any of our property or the operation or use of any of our property;

o liens on our pollution control and sewage and solid waste disposal facilities incurred in connection with the issuance of industrial development revenue bonds;

o any right which any governmental authority may have by virtue of any franchise, license, contract or statute to purchase any of our property on payment of reasonable compensation, or to terminate any franchise, license or other rights or to regulate our property and business;

o any liens that have been bonded for the full amount in dispute;

o prepaid liens;

o liens resulting from good faith deposits made in connection with bids, tenders, contracts or leases to which we are a party, and liens resulting from deposits made to secure our public or statutory obligations;

o the pledge or assignment in the ordinary course of business of electricity, gas or steam accounts receivable or customers' installment paper;

o rights reserved to or vested in others to take or receive any part of the electricity, gas, steam or any by-products generated or produced by any of our properties;

o any landlord's lien;

o any lien of the trustee for payment for services, reasonable expenses, disbursements and advances, or for indemnification payments; and

o liens not otherwise permitted if, at the time we incur the lien and after giving effect to the lien, the aggregate of all obligations secured by the lien does not exceed 10% of our tangible net worth, as defined in the indenture.

This restriction will not apply to or prevent the creation or existence of leases we enter into, or on existing property we acquire, in the ordinary course of our business. (Section 608).

Consolidation, Merger and Sale of Assets

The indenture provides that we will not consolidate with or merge into any other corporation, or sell all or substantially all of our assets to any other person unless:

o the continuing corporation or the purchasers of assets, as the case may be, will be an entity organized and existing under the laws of the United States, any state of the United States or the District of Columbia, and the entity will expressly assume the payment of the principal of, and premium, if any, or interest on, the debt securities outstanding and the performance and observance of all of our covenants and conditions under the indenture by executing a supplemental indenture satisfactory to the trustee; and

o after giving effect to the transaction, no event which, after notice or lapse of time, would become a default under the indenture, will have occurred or be continuing. (Section 1101).

The indenture further provides that our successor will be substituted for us, after which all of our obligations under the indenture will terminate. (Section 1102).

-12-

Events of Default

Each of the following will be an event of default with respect to the senior debentures:

o failure to pay interest on the senior debentures within 60 days after a due date;

o failure to pay principal of, or premium, if any, on the senior debentures within 10 days after a due date;

o failure to perform or satisfy any of our other covenants or warranties in the indenture, which failure continues for 60 days after we receive notice of the failure from the trustee or the holders of at least 33% in principal amount of the senior debentures;

o specified events relating to our bankruptcy, insolvency or reorganization. (Section 801).

If an event of default occurs and continues, then either the trustee or the holders of at least 33% in principal amount of the outstanding senior debentures in default may declare the principal amount of the senior debentures immediately due and payable. (Section 802).

The trustee can require that it be indemnified before it enforces the indenture or any outstanding senior debentures. (Section 903). Subject to some limitations, holders of a majority in principal amount of the outstanding senior debentures can direct the trustee in its exercise of any trust or power. (Section 812). The trustee does not have to give holders notice of any continuing default, except a default in payment of principal or interest, if it in good faith determines that withholding notice is in the interests of the holders. (Section 902). We are required to give the trustee a certificate certifying as to our compliance with all conditions and covenants under the indenture at least once a year. (Section 606).

Modification of the Indenture

The holders of at least a majority in principal amount of outstanding senior debentures may waive, subject to the limitations described below, any existing default and its consequences under the indenture. These holders cannot, however, waive a default in the payment of the principal of, or premium, if any, or interest on, any senior debentures or a default in respect of a provision we describe in the following paragraph. (Section 813). These defaults cannot be waived without the consent of each holder of the outstanding senior debentures.

With the consent of the holders of at least a majority in aggregate principal amount of outstanding senior debentures, we and the trustee can enter into supplemental indentures to amend or modify the indenture. However, we cannot make modifications or amendments without the consent of all of the holders of the outstanding senior debentures if the amendments or modifications would:

o change the stated maturity, reduce the principal amount of, or reduce the rate of interest on, the senior debentures;

o change the coin or currency or the property in which we must pay principal of, or premium, if any, or interest on, the senior debentures;

o impair the right to institute suit for the enforcement of any payment of principal of, or premium or interest on, the senior debentures after the due date of the payment;

o reduce the percentage in principal amount of the outstanding senior debentures, the consent of which is required to enter into any supplemental indenture;

o reduce the amount of senior debentures whose holders must consent to an amendment or waiver of the provisions of the indenture; or

-13-

o make modifications to any of the provisions we describe in this paragraph and in the paragraph immediately above. (Section 1202).

We cannot enter into supplemental indentures to amend or modify the indenture in ways that affect other series of debt securities under the indenture without the consent of the holders of at least a majority in aggregate principal amount of all securities issued under the indenture that will be affected by the amendment, voting together as one class. Further, if any amendment or modification would have any of the effects described in the previous two paragraphs, and would affect more than one series of securities issued under the indenture, then we cannot make the amendment or modifications without the consent of all of the holders of the securities issued under the indenture that would be affected by them.

We and the trustee can also enter into supplemental indentures to amend or modify the indenture or the senior debentures without the consent of any holders of the senior debentures. We can only do so if those amendments or modifications would be limited to specific purposes, including:

o showing that another person has succeeded us and assumed our obligations under the covenants of the indenture and the senior debentures;

o adding to our covenants under the indenture for the benefit of all holders of debt securities under the indenture or surrender any right or power we have under the indenture;

o adding to, changing or eliminating any of the provisions of the indenture in respect of the senior debentures, but only if the change does not adversely affect the rights of holders of the senior debentures under the indenture in any material respect;

o establish the form or terms of debt securities of any series;

o evidencing the appointment of a successor trustee or a change in any of the provisions of the indenture to facilitate administration by more than one trustee; or

o making clarifying changes to ambiguous, incorrect or inconsistent language in the indenture or the senior debentures that do not adversely affect the rights of the holders of the senior debentures under the indenture in any material respect. (Section 1201).

Defeasance

The indenture provides that we can at any time terminate almost all of our obligations with respect to any outstanding senior debentures and the indenture. We cannot, however terminate some obligations, including our obligations to register the transfer or exchange of the senior debentures, replace mutilated, destroyed, lost or stolen senior debentures, to maintain agencies in respect of the senior debentures and hold moneys for payment in trust. (Sections 701 and 702).

If we desire to exercise our option to satisfy and discharge our obligations under the indenture (a defeasance), then we must deposit in trust with the trustee money or U.S. government obligations sufficient to pay the outstanding principal amount of the senior debentures as well as the interest on the senior debentures to maturity. We must also comply with some other provisions. In particular, we must obtain:

o an opinion of tax counsel that the defeasance will not result in recognition of any gain or loss to holders of the senior debentures for federal income tax purposes (Officers' Certificate);

o an opinion of counsel that any U.S. government obligation that we deposit in trust meet the requirements of U.S. government obligations set forth in the indenture; and

-14-

o an opinion of a nationally recognized independent public accountant to the effect that we have deposited with the trustee money or U.S. government obligations sufficient to pay the outstanding principal amount of the senior debentures as well as the interest of the senior debentures to maturity.

Governing Law

The indenture and the senior debentures will be governed by, and construed in accordance with, the laws of the State of New York. (Section 112).

The Trustee

Bank One Trust will act as trustee, registrar, transfer agent and paying agent for the senior debentures. We can remove the trustee with or without cause so long as no event which is, or after notice or lapse of time would become, an event of default shall have occurred and be continuing.

We and certain of our affiliates maintain banking and other business relationships in the ordinary course of business with the trustee and its affiliates. In addition, the trustee and certain of its affiliates may serve as trustee for other securities issued by us or by our affiliates.

To the extent provided in the indenture, the trustee will have a prior claim on amounts held by it under the indenture for the payment of its compensation and expenses and for the repayment of advances made by it to effect performance of some covenants in the indenture.

Book-Entry Delivery and Settlement

We will issue the senior debentures in whole or in part in the form of one or more global certificates or notes, which we refer to as global securities. We will deposit the global securities with or on behalf of The Depository Trust Company, referred to as DTC, and registered in the name of Cede & Co., as nominee of DTC, or else the global securities will remain in the custody of the trustee in accordance with the FAST Balance Certificate Agreement between DTC and the trustee.

DTC has advised us that:

o 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 under Section 17A of the Securities Exchange Act of 1934;

o DTC holds securities that its direct participants deposit with DTC and facilitates the settlement among direct participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in direct participants' accounts, thereby eliminating the need for physical movement of securities certificates;

o direct participants include securities brokers and dealers, trust companies, clearing corporations and other organizations;

o DTC is owned by a number of its direct participants and by the New York Stock Exchange, Inc., the American Stock Exchange LLC and the National Association of Securities Dealers, Inc.;

o access to the DTC system is also available to indirect participants such as securities brokers and dealers, banks and trust companies that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly; and

o the rules applicable to DTC and its direct and indirect participants are on file with the SEC.

-15-

We have provided the following descriptions of the operations and procedures of DTC solely as a matter of convenience. These operations and procedures are solely within the control of DTC and are subject to change by them from time to time. Neither we, the underwriters nor the trustee take any responsibility for these operations or procedures, and you are urged to contact DTC or its participants directly to discuss these matters.

We expect that under procedures established by DTC:

o upon deposit of the global securities with DTC or its custodian, DTC will credit on its internal system the accounts of direct participants designated by the underwriters with portions of the principal amounts of the global securities; and

o ownership of the senior debentures will be shown on, and the transfer of ownership of the senior debentures will be effected only through, records maintained by DTC or its nominee, with respect to interests of direct participants, and the records of direct and indirect participants, with respect to interests of persons other than participants.

The laws of some jurisdictions require that purchasers of securities take physical delivery of those securities in the form of a certificate. For that reason, it may not be possible to transfer interests in a global security to those persons. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a person having an interest in a global security to pledge or transfer that interest to persons or entities that do not participate in DTC's system, or otherwise to take actions in respect of that interest, may be affected by the lack of a physical definitive security in respect of that interest.

So long as DTC or its nominee is the registered owner of a global security, DTC or that nominee will be considered the sole owner or holder of the senior debentures represented by that global security for all purposes under the indenture and under the senior debentures. Except as described below, owners of beneficial interests in a global security will not be entitled to have senior debentures represented by that global security registered in their names, will not receive or be entitled to receive the senior debentures in the form of a physical certificate and will not be considered the owners or holders of the senior debentures under the indenture or under the senior debentures, and may not be entitled to give the trustee directions, instructions or approvals. For that reason, each holder owning a beneficial interest in a global security must rely on DTC's procedures and, if that holder is not a direct or indirect participant in DTC, on the procedures of the DTC participant through which that holder owns its interest, to exercise any rights of a holder of senior debentures under the indenture or the global security.

Neither we nor the trustee will have any responsibility or liability for any aspect of DTC's records relating to the senior debentures or relating to payments made by DTC on account of the senior debentures, or any responsibility to maintain, supervise or review any of DTC's records relating to the senior debentures.

We will make payments on the senior debentures represented by the global securities to DTC or its nominee, as the registered owner of the senior debentures. We expect that when DTC or its nominee receives any payment on the senior debentures represented by a global security, DTC will credit participants' accounts with payments in amounts proportionate to their beneficial interests in the global security as shown in DTC's records. We also expect that payments by DTC's participants to owners of beneficial interests in the global security held through those participants will be governed by standing instructions and customary practice as is now the case with securities held for the accounts of customers registered in the names of nominees for such customers. DTC's participants will be responsible for those payments.

Payments on the senior debentures represented by the global securities will be made in immediately available funds. Transfers between participants in DTC will be made in accordance with DTC's rules and will be settled in immediately available funds.

-16-

Certificated Senior Debentures

We will issue certificated senior debentures to each person that DTC identifies as the beneficial owner of senior debentures represented by the global securities upon surrender by DTC of the global securities only if:

o DTC notifies us that it is no longer willing or able to act as a depository for the global securities, and we have not appointed a successor depository within 90 days of that notice;

o an event of default with respect to the senior debentures has occurred and is continuing; or

o we decide not to have the senior debentures represented by a global security.

Neither we nor the trustee will be liable for any delay by DTC, its nominee or any direct or indirect participant in identifying the beneficial owners of the related senior debentures. We and the trustee may conclusively rely on, and will be protected in relying on, instructions from DTC or its nominee, including instructions about the registration and delivery, and the respective principal amounts, of the senior debentures to be issued.

-17-

UNDERWRITING

Merrill Lynch, Pierce, Fenner & Smith Incorporated and Barclays Capital Inc. are acting as representatives of each of the underwriters named below. Subject to the terms and conditions set forth in a purchase agreement among us and the underwriters, we have agreed to sell to the underwriters, and each of the underwriters severally and not jointly has agreed to purchase from us, the principal amount of senior debentures set forth opposite its name below.

                Underwriters                    Principal Amount
                ------------                    ----------------

Merrill Lynch, Pierce, Fenner & Smith
                     Incorporated...............  $
Barclays Capital Inc............................
                                                  ------------
Total...........................................  $100,000,000
                                                  ============

The underwriters have agreed, subject to the terms and conditions contained in the purchase agreement, to purchase all of the senior debentures sold under the purchase agreement if any of these senior debentures are purchased. If an underwriter defaults, the purchase agreement provides that the purchase commitments of the non-defaulting underwriters may be increased or the purchase agreement may be terminated.

The underwriters are offering the senior debentures, subject to prior sale, when, as and if issued to and accepted by them, subject to approval of legal matters by their counsel, including the validity of the senior debentures, and other conditions contained in the purchase agreement, such as the receipt by the underwriters of officer's certificates and legal opinions. The underwriters reserve the right to withdraw, cancel or modify offers to the public and to reject orders in whole or in part.

The senior debentures are a new issue of securities with no established trading market. The underwriters have advised us that they intend to make a market in the senior debentures but the underwriters are not obligated to do so and may discontinue market making at any time without notice. No assurance can be given as to the liquidity of the trading market for the senior debentures.

Commissions and Discounts

The representatives have advised us that the underwriters propose initially to offer the senior debentures to the public at the public offering price on the cover page of the prospectus, and to certain dealers at that price less a concession not in excess of ____% of the principal amount of the senior debentures. The underwriters may allow, and the dealers may reallow, a discount not in excess of ____% of the principal amount of the senior debentures to other dealers. After the initial public offering, the public offering price, concession and discount may be changed.

The expenses of this offering, not including the underwriting discount, are estimated at $225,000 and are payable by us.

No Sale of Similar Securities

We have agreed, with exceptions, not to sell or transfer any of our senior debentures for 15 days after the date of this prospectus without first obtaining the written consent of Merrill Lynch on behalf of the underwriters. Specifically, we have agreed not to directly or indirectly:

o Offer, pledge, sell or contract to sell any debt securities;

o Sell any option or contract to purchase any debt securities;

o Purchase any option or contract to sell any debt securities;

o Grant any option, right or warrant to sell any debt securities;

-18-

o Lend or otherwise dispose of or transfer any debt securities;

o File a registration statement related to the debt securities; or

o Enter into any swap or other agreement that transfers, in whole or in part, the economic consequence of ownership of any debt securities, whether any such swap or transaction is to be settled by delivery of debt securities or other securities, in cash or otherwise.

This lockup provision applies to the debt securities and to securities convertible into or exchangeable or exercisable for or repayable with the debt securities.

Indemnification

We have agreed to indemnify the underwriters against certain liabilities, including certain liabilities under the Securities Act of 1933, or to contribute to payments the underwriters may be required to make in respect of those liabilities.

Price Stabilization and Short Position

In connection with the offering, the underwriters are permitted to engage in transactions that stabilize the market price of the senior debentures. Such transactions consist of bids or purchases to peg, fix or maintain the price of the senior debentures.

If the underwriters create a short position in the senior debentures in connection with the offering, i.e., if they sell more senior debentures than are listed on the cover page of this prospectus, then the representatives may reduce that short position by purchasing senior debentures in the open market. Purchases of our senior debentures to stabilize or reduce a short position could cause the price of our senior debentures to be higher than it might be in the absence of such purchases.

In general, purchases of a security to stabilize the price or to reduce a short position may cause the price of the security to be higher than it might be in the absence of these purchases.

Neither we nor any of the underwriters 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 senior debentures. In addition, neither we nor any of the underwriters makes any representation that the representatives will engage in these transactions or that these transactions, once commenced, will not be discontinued without notice.

Other Relationships

Some of the underwriters or their affiliates have provided investment or commercial banking services to us in the past and are likely to do so in the future. They receive customary fees and commissions for these services. In particular, affiliates of Merrill Lynch, Pierce, Fenner & Smith Incorporated and Barclays Capital Inc. are lenders under our credit facility.

Item 15. Indemnification of Directors and Officers.

The Iowa Business Corporation Act ("IBCA") grants each corporation organized thereunder, such as the Registrant, the power to indemnify its directors and officers against liabilities for certain of their acts. The Registrant's Restated Articles of Incorporation provide that the Registrant shall indemnify its directors and officers to the fullest extent permitted by the IBCA and may, but is not required to, purchase and maintain insurance on behalf of any person who is or was a director, officer, employee or agent of the Registrant, or is or was serving at the request of the Registrant as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against any liability asserted and incurred against such person in any such capacity or arising out of such person's status as such, whether or not the Registrant would have the power to indemnify such person against such liability under the provisions thereof. The Registrant's Bylaws permit the Registrant to maintain such insurance and further provide that the Registrant shall indemnify directors and officers of the Registrant to the full extent permitted by the IBCA and advance any and all reasonable expenses incurred in any proceeding to which any such director or officer is a party because he or she is or was a director or officer.

Under the IBCA, directors of the Registrant are not subject to personal liability to the Registrant or its shareowners for acts or failures to act except under certain circumstances. In addition, the IBCA grants corporations organized thereunder, such as the Registrant, the authority to adopt a provision in their respective articles of incorporation eliminating or limiting, with certain exceptions, the personal liability of a director to the corporation or to its shareowners for monetary damages for certain breaches of fiduciary duty as a director. The Registrant's Restated Articles of Incorporation eliminates the personal liability of each director except for liability (i) for any breach of the director's duty of loyalty to the Registrant or its shareowners, (ii) for acts or omissions not in good faith or which involve any intentional misconduct or knowing violation of the law, (iii) for any transaction from which the director derived an improper personal benefit, or (iv) under Section 490.833 of the IBCA relating to liability for unlawful distribution.

The foregoing statements are subject to the detailed provisions of the IBCA and the Restated Articles of Incorporation and Bylaws of the Registrant and should be read in connection with these other documents for a more full understanding of their effect on the Registrant.

The indemnification provided by the Registrant is not exclusive of any other rights to which a director or officer of the Registrant may be entitled. The Registrant also carries directors' and officers' liability insurance. The Registrant's directors' and officers' insurance policies are designed to reimburse the Registrant for any payments made by it pursuant to the foregoing indemnification provisions.

Item 16. Exhibits and Financial Statement Schedules.

The exhibits listed in the accompanying Exhibit Index are filed or incorporated by reference as part of this Registration Statement.

Item 17. Undertakings.

(a) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(b) The undersigned registrant hereby undertakes that:

(1) For purposes of determining any liability under the Securities Act of 1933, the information omitted from the form of prospectus filed as part of this Registration Statement in reliance upon Rule 430A and contained in a form of prospectus filed by the Registrant pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this Registration Statement as of the time it was declared effective.

(2) For the purpose of determining any liability under the Securities Act of 1933, each post-effective amendment that contains a form of prospectus shall be deemed to be a new Registration Statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

SECTION 103. FORM OF DOCUMENTS DELIVERED TO TRUSTEE.

In any case where several matters are required to be certified by, or covered by an opinion of, any specified Person, it is not necessary that all such matters be certified by, or covered by the opinion of, only one such Person, or that they be so certified or covered by only one document, but one such Person may certify or give an opinion with respect to some matters and one or more other such Persons as to other matters, and any such Person may certify or give an opinion as to such matters in one or several documents.

Any certificate or opinion of an officer of the Company may be based, insofar as it relates to legal matters, upon a certificate or opinion of, or representations by, counsel, unless such officer knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to the matters upon which such Officer's Certificate or opinion are based are erroneous. Any such certificate or Opinion of Counsel may be based, insofar as it relates to factual matters, upon a certificate or opinion of, or representations by, an officer or officers of the Company stating that the information with respect to such factual matters is in the possession of the Company, unless such counsel knows, or in the exercise of reasonable care should know, that the certificate or opinion or representations with respect to such matters are erroneous.

Where any Person is required to make, give or execute two or more applications, requests, consents, certificates, statements, opinions or other instruments under this Indenture, they may, but need not, be consolidated and form one instrument.

Whenever, subsequent to the receipt by the Trustee of any Board Resolution, Officer's Certificate, Opinion of Counsel or other document or instrument, a clerical, typographical or other inadvertent or unintentional error or omission shall be discovered therein, a new document or instrument may be substituted therefor in corrected form with the same force and effect as if originally filed in the corrected form and, irrespective of the date or dates of the actual execution and/or delivery thereof, such substitute document or instrument shall be deemed to have been executed and/or delivered as of the date or dates required with respect to the document or instrument for which it is substituted. Anything in this Indenture to the contrary notwithstanding, if any such corrective document or instrument indicates that action has been taken by or at the request of the Company which could not have been taken had the original document or instrument not contained such error or omission, the action so taken shall not be invalidated or otherwise rendered ineffective but shall be and remain in full force and effect, except to the extent that such action was a result of willful misconduct or bad faith. Without limiting the generality of the foregoing, any Securities issued under the authority of such defective document or instrument shall nevertheless be the valid obligations of the Company entitled to the benefits of this Indenture equally and ratably with all other Outstanding Securities, except as aforesaid.

SECTION 104. ACTS OF HOLDERS.

(a) Any request, demand, authorization, direction, notice, consent, election, waiver or other action provided by this Indenture to be made, given or taken by Holders may be embodied in and evidenced by one or more instruments of substantially similar tenor signed by such Holders in

-9-

person or by an agent duly appointed in writing or, alternatively, may be embodied in and evidenced by the record of Holders voting in favor thereof, either in person or by proxies duly appointed in writing, at any meeting of Holders duly called and held in accordance with the provisions of Article Thirteen, or a combination of such instruments and any such record. Except as herein otherwise expressly provided, such action shall become effective when such instrument or instruments or record or both are delivered to the Trustee and, where it is hereby expressly required, to the Company. Such instrument or instruments and any such record (and the action embodied therein and evidenced thereby) are herein sometimes referred to as the "Act" of the Holders signing such instrument or instruments and so voting at any such meeting. Proof of execution of any such instrument or of a writing appointing any such agent, or of the holding by any Person of a Security, shall be sufficient for any purpose of this Indenture and (subject to Section 901) conclusive in favor of the Trustee and the Company, if made in the manner provided in this Section. The record of any meeting of Holders shall be proved in the manner provided in Section 1306.

(b) The fact and date of the execution by any Person of any such instrument or writing may be proved by the affidavit of a witness of such execution or by a certificate of a notary public or other officer authorized by law to take acknowledgments of deeds, certifying that the individual signing such instrument or writing acknowledged to him the execution thereof or may be proved in any other manner which the Trustee and the Company deem sufficient. Where such execution is by a signer acting in a capacity other than his individual capacity, such certificate or affidavit shall also constitute sufficient proof of his authority.

(c) The principal amount (except as otherwise contemplated in clause
(y) of the proviso to the definition of Outstanding) and serial numbers of Securities held by any Person, and the date of holding the same, shall be proved by the Security Register.

(d) Any request, demand, authorization, direction, notice, consent, election, waiver or other Act of a Holder shall bind every future Holder of the same Security and the Holder of every Security issued upon the registration of transfer thereof or in exchange therefor or in lieu thereof in respect of anything done, omitted or suffered to be done by the Trustee or the Company in reliance thereon, whether or not notation of such action is made upon such Security.

(e) Until such time as written instruments shall have been delivered to the Trustee with respect to the requisite percentage of principal amount of Securities for the action contemplated by such instruments, any such instrument executed and delivered by or on behalf of a Holder may be revoked with respect to any or all of such Securities by written notice by such Holder or any subsequent Holder, proven in the manner in which such instrument was proven.

(f) Securities of any series, or any Tranche thereof, authenticated and delivered after any Act of Holders may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any action taken by such Act of Holders. If the Company shall so determine, new Securities of any series, or any Tranche thereof, so modified as to conform, in the opinion of the Trustee and the Company, to such action may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series or Tranche.

(g) If the Company shall solicit from Holders any request, demand, authorization, direction, notice, consent, waiver or other Act, the Company may, at its option, by Company Order, fix in advance a record date for the determination of Holders entitled to give such request, demand, authorization, direction, notice, consent, waiver or other Act, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other Act may be given before or after such record date, but only the Holders of record at the close of business on the record date shall be deemed to be Holders for the

-10-

purposes of determining whether Holders of the requisite proportion of the Outstanding Securities have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other Act, and for that purpose the Outstanding Securities shall be computed as of the record date.

SECTION 105. NOTICES, ETC. TO TRUSTEE AND COMPANY.

Any request, demand, authorization, direction, notice, consent, election, waiver or Act of Holders or other document provided or permitted by this Indenture to be made upon, given or furnished to, or filed with, the Trustee by any Holder or by the Company, or the Company by the Trustee or by any Holder, shall be sufficient for every purpose hereunder (unless otherwise herein expressly provided) if in writing and delivered personally to an officer or other responsible employee of the addressee, or transmitted by facsimile transmission, telex or other direct written electronic means to such telephone number or other electronic communications address as the parties hereto shall from time to time designate, or transmitted by registered mail, charges prepaid, to the applicable address set opposite such party's name below or to such other address as either party hereto may from time to time designate:

SECTION 106. NOTICE TO HOLDERS OF SECURITIES; WAIVER.

Except as otherwise expressly provided herein, where this Indenture provides for notice to Holders of any event, such notice shall be sufficiently given, and shall be deemed given, to Holders if in writing and mailed, first-class postage prepaid, to each Holder affected by such event, at the address of such Holder as it appears in the Security Register, not later than the latest date, and not earlier than the earliest date, prescribed for the giving of such notice.

In case by reason of the suspension of regular mail service or by reason of any other cause it shall be impracticable to give such notice to Holders by mail, then such notification as shall be made with the approval of the Trustee shall constitute a sufficient notification for every purpose hereunder. In any case where notice to

-11-

Holders is given by mail, neither the failure to mail such notice, nor any defect in any notice so mailed, to any particular Holder shall affect the sufficiency of such notice with respect to other Holders.

Any notice required by this Indenture may be waived in writing by the Person entitled to receive such notice, either before or after the event otherwise to be specified therein, and such waiver shall be the equivalent of such notice. Waivers of notice by Holders shall be filed with the Trustee, but such filing shall not be a condition precedent to the validity of any action taken in reliance upon such waiver.

SECTION 107. CONFLICT WITH TRUST INDENTURE ACT.

If any provision of this Indenture limits, qualifies or conflicts with another provision hereof which is required or deemed to be included in this Indenture by, or is otherwise governed by, any of the provisions of the Trust Indenture Act, such other provision shall control; and if any provision hereof otherwise conflicts with the Trust Indenture Act, the Trust Indenture Act shall control.

The Article and Section headings in this Indenture and the Table of Contents are for convenience only and shall not affect the construction hereof.

SECTION 109. SUCCESSORS AND ASSIGNS.

All covenants and agreements in this Indenture by the Company and Trustee shall bind their respective successors and assigns, whether so expressed or not.

Nothing in this Indenture or the Securities, express or implied, shall give to any Person, other than the parties hereto, their successors hereunder, and the Holders, any benefit or any legal or equitable right, remedy or claim under this Indenture.

This Indenture and the Securities shall be governed by and construed in accordance with the laws of the State of New York, except to the extent that the law of any other jurisdiction shall be mandatorily applicable.

SECTION 113. LEGAL HOLIDAYS.

In any case where any Interest Payment Date, Redemption Date or Stated Maturity of any Security shall not be a Business Day at any Place of Payment, then (notwithstanding any other provision of this Indenture or of the Securities other than a provision in Securities of any series, or any Tranche thereof, or in the Board Resolution or Officer's Certificate which establishes the terms of the Securities of such series or Tranche, which specifically states that such provision shall apply in lieu of this Section) payment of interest or principal and premium, if any, need not be made at such Place of Payment on such date, but may be made on the next succeeding Business Day at such Place of Payment, except that if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day in each

SECTION 302. DENOMINATIONS.

Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, or any Tranche thereof, the Securities of each series shall be issuable in denominations of $1,000 and any integral multiple thereof.

SECTION 303. EXECUTION, AUTHENTICATION, DELIVERY AND DATING.

Unless otherwise provided as contemplated by Section 301 with respect to any series of Securities, or any Tranche thereof, the Securities shall be executed on behalf of the Company by an Authorized Officer and may have the corporate seal of the Company affixed thereto or reproduced thereon and attested by any other Authorized Officer. The signature of any or all of these officers on the Securities may be manual or facsimile.

Securities bearing the manual or facsimile signatures of individuals who were at the time of execution Authorized Officers of the Company shall bind the Company, notwithstanding that such individuals or any of them have ceased to hold such offices prior to the authentication and delivery of such Securities or did not hold such offices at the date of such Securities.

The Trustee shall authenticate and deliver Securities of a series, for original issue, at one time or from time to time in accordance with the Company Order referred to below, upon receipt by the Trustee of:

(a) the instrument or instruments establishing the form or forms and terms of such series, as provided in Sections 201 and 301;

(b) a Company Order requesting the authentication and delivery of such Securities and, to the extent that the terms of such Securities shall not have been established in an indenture

-16-

supplemental hereto or in a Board Resolution, or in an Officer's Certificate pursuant to a supplemental indenture or Board Resolution, all as contemplated by Sections 201 and 301, either (1) establishing such terms or (2) in the case of Securities of a series subject to a Periodic Offering, specifying procedures, acceptable to the Trustee, by which such terms are to be established (which procedures may provide, to the extent acceptable to the Trustee, for authentication and delivery pursuant to oral or electronic instructions from the Company or any agent or agents thereof, which oral instructions are to be promptly confirmed electronically or in writing), in either case in accordance with the instrument or instruments delivered pursuant to clause (a) above;

(c) the Securities of such series, executed on behalf of the Company by an Authorized Officer;

(d) an Opinion of Counsel to the effect that:

(1) the form or forms of such Securities have been duly authorized by the Company and have been established in conformity with the provisions of this Indenture;

(2) the terms of such Securities have been duly authorized by the Company and have been established in conformity with the provisions of this Indenture; and

(3) such Securities, when authenticated and delivered by the Trustee and issued and delivered by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will have been duly issued under this Indenture and will constitute valid and legally binding obligations of the Company, entitled to the benefits provided by this Indenture, and enforceable in accordance with their terms, subject, as to enforcement, to laws relating to or affecting generally the enforcement of creditors' rights, including, without limitation, bankruptcy and insolvency laws and to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law);

provided, however, that, with respect to Securities of a series subject to a Periodic Offering, the Trustee shall be entitled to receive such Opinion of Counsel only once at or prior to the time of the first authentication of such Securities (provided that such Opinion of Counsel addresses the authentication and delivery of all Securities of such series) and that in lieu of the opinions described in clauses (2) and (3) above Counsel may opine that:

(x) when the terms of such Securities shall have been established pursuant to a Company Order or Orders or pursuant to such procedures (acceptable to the Trustee) as may be specified from time to time by a Company Order or Orders, all as contemplated by and in accordance with the instrument or instruments delivered pursuant to clause (a) above, such terms will have been duly authorized by the Company and will have been established in conformity with the provisions of this Indenture; and

(y) such Securities, when authenticated and delivered by the Trustee in accordance with this Indenture and the Company Order or Orders or specified procedures referred to in paragraph (x) above and issued and delivered by the Company in the manner and subject to any conditions specified in such Opinion of Counsel, will have been duly issued under this Indenture and will constitute valid and legally binding obligations of the Company, entitled to the benefits provided by the Indenture, and enforceable in accordance with their terms, subject, as to enforcement, to laws relating to or affecting generally the enforcement of creditors' rights, including, without limitation, bankruptcy and insolvency laws, and to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

-17-

With respect to Securities of a series subject to a Periodic Offering, the Trustee may conclusively rely, as to the authorization by the Company of any of such Securities, the form and terms thereof and the legality, validity, binding effect and enforceability thereof, upon the Opinion of Counsel and other documents delivered pursuant to Sections 201 and 301 and this Section, as applicable, at or prior to the time of the first authentication of Securities of such series unless and until such opinion or other documents have been superseded or revoked or expire by their terms. In connection with the authentication and delivery of Securities of a series subject to a Periodic Offering, the Trustee shall be entitled to assume that the Company's instructions to authenticate and deliver such Securities do not violate any rules, regulations or orders of any Governmental Authority having jurisdiction over the Company.

If the form or terms of the Securities of any series have been established by or pursuant to a Board Resolution or an Officer's Certificate as permitted by Sections 201 or 301, the Trustee shall not be required to authenticate such Securities if the issuance of such Securities pursuant to this Indenture will affect the Trustee's own rights, duties or immunities under the Securities and this Indenture or otherwise in a manner which is not reasonably acceptable to the Trustee.

Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities, or any Tranche thereof, each Security shall be dated the date of its authentication.

Unless otherwise specified as contemplated by Section 301 with respect to any series of Securities, or any Tranche thereof, no Security shall be entitled to any benefit under this Indenture or be valid or obligatory for any purpose unless there appears on such Security a certificate of authentication substantially in the form provided for herein executed by the Trustee or its agent by manual signature, and such certificate upon any Security shall be conclusive evidence, and the only evidence, that such Security has been duly authenticated and delivered hereunder and is entitled to the benefits of this Indenture. Notwithstanding the foregoing, if any Security shall have been authenticated and delivered hereunder to the Company, or any Person acting on its behalf, but shall never have been issued and sold by the Company, and the Company shall deliver such Security to the Security Registrar for cancellation as provided in Section 309 together with a written statement (which need not comply with Section 102 and need not be accompanied by an Officer's Certificate and an Opinion of Counsel) stating that such Security has never been issued and sold by the Company, for all purposes of this Indenture such Security shall be deemed never to have been authenticated and delivered hereunder and shall never be entitled to the benefits hereof.

SECTION 304. TEMPORARY SECURITIES.

Pending the preparation of definitive Securities of any series, or any Tranche thereof, the Company may execute, and upon Company Order the Trustee shall authenticate and deliver, temporary Securities which are printed, lithographed, typewritten, mimeographed or otherwise produced, in any authorized denomination, substantially of the tenor of the definitive Securities in lieu of which they are issued, with such appropriate insertions, omissions, substitutions and other variations as the officers executing such Securities may determine, as evidenced by their execution of such Securities; provided, however, that temporary Securities need not recite specific redemption, sinking fund, conversion or exchange provisions.

Unless otherwise specified as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, after the preparation of definitive Securities of such series or Tranche, the temporary Securities of such series or Tranche shall be exchangeable, without charge to the Holder thereof, for definitive Securities of such series or Tranche upon surrender of such temporary Securities at the office or agency of the Company maintained pursuant to Section 602 in a Place of Payment for such Securities. Upon such surrender of temporary Securities, the Company shall, except as aforesaid, execute and the Trustee shall authenticate and deliver in exchange therefor definitive Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount.

-18-

Until exchanged in full as hereinabove provided, temporary Securities shall in all respects be entitled to the same benefits under this Indenture as definitive Securities of the same series and Tranche and of like tenor authenticated and delivered hereunder.

SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.

The Company shall cause to be kept in each office designated pursuant to
Section 602, with respect to the Securities of each series or any Tranche thereof, a register (all registers kept in accordance with this Section being collectively referred to as the "Security Register") in which, subject to such reasonable regulations as it may prescribe, the Company shall provide for the registration of Securities of such series or Tranche and the registration of transfer thereof. The Company shall designate one Person to maintain the Security Register for the Securities of each series on a consolidated basis, and such Person is referred to herein, with respect to such series, as the "Security Registrar." Anything herein to the contrary notwithstanding, the Company may designate one or more of its offices as an office in which a register with respect to the Securities of one or more series, or any Tranche or Tranches thereof, shall be maintained, and the Company may designate itself the Security Registrar with respect to one or more of such series. The Security Register shall be open for inspection by the Trustee and the Company at all reasonable times.

Except as otherwise specified as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, upon surrender for registration of transfer of any Security of such series or Tranche at the office or agency of the Company maintained pursuant to Section 602 in a Place of Payment for such series or Tranche, the Company shall execute, and the Trustee shall authenticate and deliver, in the name of the designated transferee or transferees, one or more new Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount.

Except as otherwise specified as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, any Security of such series or Tranche may be exchanged at the option of the Holder, for one or more new Securities of the same series and Tranche, of authorized denominations and of like tenor and aggregate principal amount, upon surrender of the Securities to be exchanged at any such office or agency. Whenever any Securities are so surrendered for exchange, the Company shall execute, and the Trustee shall authenticate and deliver, the Securities which the Holder making the exchange is entitled to receive.

All Securities delivered upon any registration of transfer or exchange of Securities shall be valid obligations of the Company, evidencing the same debt, and entitled to the same benefits under this Indenture, as the Securities surrendered upon such registration of transfer or exchange.

Every Security presented or surrendered for registration of transfer or for exchange shall (if so required by the Company, the Trustee or the Security Registrar) be duly endorsed or shall be accompanied by a written instrument of transfer in form satisfactory to the Company, the Trustee or the Security Registrar, as the case may be, duly executed by the Holder thereof or his attorney duly authorized in writing.

Unless otherwise specified as contemplated by Section 301 with respect to Securities of any series, or any Tranche thereof, no service charge shall be made for any registration of transfer or exchange of Securities, but the Company may require payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in connection with any registration of transfer or exchange of Securities, other than exchanges pursuant to Section 304, 406 or 1206 not involving any transfer.

The Company shall not be required to execute or to provide for the registration of transfer of or the exchange of (a) Securities of any series, or any Tranche thereof, during a period of 15 days immediately preceding the date notice is to be given identifying the serial numbers of the Securities of such series or Tranche called for redemption or (b) any Security so selected for redemption in whole or in part, except the unredeemed portion of any Security being redeemed in part.

-19-

SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES.

If any mutilated Security is surrendered to the Trustee, the Company shall execute and the Trustee shall authenticate and deliver in exchange therefor a new Security of the same series and Tranche, and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

If there shall be delivered to the Company and the Trustee (a) evidence to their satisfaction of the ownership of and the destruction, loss or theft of any Security and (b) such security or indemnity as may be reasonably required by them to save each of them and any agent of either of them harmless, then, in the absence of notice to the Company or the Trustee that such Security is held by a Person purporting to be the owner of such Security, the Company shall execute and the Trustee shall authenticate and deliver, in lieu of any such destroyed, lost or stolen Security, a new Security of the same series and Tranche, and of like tenor and principal amount and bearing a number not contemporaneously outstanding.

Notwithstanding the foregoing, in case any such mutilated, destroyed, lost or stolen Security has become or is about to become due and payable, the Company in its discretion may, instead of issuing a new Security, pay such Security.

Upon the issuance of any new Security under this Section, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation thereto and any other reasonable expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security of any series issued pursuant to this Section in lieu of any destroyed, lost or stolen Security shall constitute an original additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Security shall be at any time enforceable by anyone other than the Holder of such new Security, and any such new Security shall be entitled to all the benefits of this Indenture equally and proportionately with any and all other Securities of such series duly issued hereunder.

The provisions of this Section are exclusive and shall preclude (to the extent lawful) all other rights and remedies with respect to the replacement or payment of mutilated, destroyed, lost or stolen Securities.

SECTION 307. PAYMENT OF INTEREST; INTEREST RIGHTS PRESERVED.

Unless otherwise specified as contemplated by Section 301 with respect to the Securities of any series, or any Tranche thereof, interest on any Security which is payable, and is punctually paid or duly provided for, on any Interest Payment Date shall be paid to the Person in whose name that Security (or one or more Predecessor Securities) is registered at the close of business on the Regular Record Date for such interest.

Subject to Section 312, any interest on any Security of any series which is payable, but is not punctually paid or duly provided for, on any Interest Payment Date (herein called "Defaulted Interest") shall forthwith cease to be payable to the Holder on the related Regular Record Date by virtue of having been such Holder, and such Defaulted Interest may be paid by the Company, at its election in each case, as provided in clause (a) or (b) below:

(a) The Company may elect to make payment of any Defaulted Interest to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on a date (herein called a "Special Record Date") for the payment of such Defaulted Interest, which shall be fixed in the following manner. The Company shall notify the Trustee in writing of the amount of Defaulted Interest proposed to be paid on each Security of such series and the date of the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the

-20-

Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a Special Record Date for the payment of such Defaulted Interest which shall be not more than 15 days and not less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The Trustee shall promptly notify the Company of such Special Record Date and, in the name and at the expense of the Company, shall promptly cause notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor to be mailed, first-class postage prepaid, to each Holder of Securities of such series at the address of such Holder as it appears in the Security Register, not less than 10 days prior to such Special Record Date. Notice of the proposed payment of such Defaulted Interest and the Special Record Date therefor having been so mailed, such Defaulted Interest shall be paid to the Persons in whose names the Securities of such series (or their respective Predecessor Securities) are registered at the close of business on such Special Record Date.

(b) The Company may make payment of any Defaulted Interest on the Securities of any series in any other lawful manner not inconsistent with the requirements of any securities exchange on which such Securities may be listed, and upon such notice as may be required by such exchange, if, after notice given by the Company to the Trustee of the proposed payment pursuant to this clause, such manner of payment shall be deemed practicable by the Trustee.

Subject to the foregoing provisions of this Section and Section 305, each Security delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Security shall carry the rights to interest accrued and unpaid, and to accrue, which were carried by such other Security.

SECTION 308. PERSONS DEEMED OWNERS.

The Company, the Trustee and any agent of the Company or the Trustee may treat the Person in whose name such Security is registered as the absolute owner of such Security for the purpose of receiving payment of principal of and premium, if any, and (subject to Sections 305 and 307) interest, if any, on such Security and for all other purposes whatsoever, whether or not such Security be overdue, and neither the Company, the Trustee nor any agent of the Company or the Trustee shall be affected by notice to the contrary.

SECTION 309. CANCELLATION BY SECURITY REGISTRAR.

All Securities surrendered for payment, redemption, registration of transfer or exchange shall, if surrendered to any Person other than the Security Registrar, be delivered to the Security Registrar and, if not theretofore canceled, shall be promptly canceled by the Security Registrar. The Company may at any time deliver to the Security Registrar for cancellation any Securities previously authenticated and delivered hereunder which the Company may have acquired in any manner whatsoever or which the Company shall not have issued and sold, and all Securities so delivered shall be promptly canceled by the Security Registrar. No Securities shall be authenticated in lieu of or in exchange for any Securities canceled as provided in this Section, except as expressly permitted by this Indenture. All canceled Securities held by the Security Registrar shall be disposed of in accordance with a Company Order delivered to the Security Registrar and the Trustee, and the Security Registrar shall promptly deliver a certificate of disposition to the Trustee and the Company unless, by a Company Order, similarly delivered, the Company shall direct that canceled Securities be returned to it. The Security Registrar shall promptly deliver evidence of any cancellation of a Security in accordance with this
Section 309 to the Trustee and the Company.

SECTION 310. COMPUTATION OF INTEREST.

Except as otherwise specified as contemplated by Section 301 for Securities of any series, or any Tranche thereof, interest on the Securities of each series shall be computed on the basis of a 360-day year consisting of twelve 30-day months and on the basis of the actual number of days elapsed within any month in relation to the deemed 30 days of such month.

-21-

SECTION 311. PAYMENT TO BE IN PROPER CURRENCY.

In the case of the Securities of any series, or any Tranche thereof, denominated in any currency other than Dollars or in a composite currency (the "Required Currency"), except as otherwise specified with respect to such Securities as contemplated by Section 301, the obligation of the Company to make any payment of the principal thereof, or the premium, if any, or interest, if any, thereon, shall not be discharged or satisfied by any tender by the Company, or recovery by the Trustee, in any currency other than the Required Currency, except to the extent that such tender or recovery shall result in the Trustee timely holding the full amount of the Required Currency then due and payable. If any such tender or recovery is in a currency other than the Required Currency, the Trustee may take such actions as it considers appropriate to exchange such currency for the Required Currency. The costs and risks of any such exchange, including without limitation the risks of delay and exchange rate fluctuation, shall be borne by the Company, the Company shall remain fully liable for any shortfall or delinquency in the full amount of Required Currency then due and payable, and in no circumstances shall the Trustee be liable therefor except in the case of its negligence or willful misconduct.

SECTION 312. EXTENSION OF INTEREST PAYMENT.

The Company shall have the right at any time, so long as the Company is not in default in the payment of interest on the Securities of any series hereunder, to extend interest payment periods on all Securities of one or more series, or Tranches thereof, if so specified as contemplated by Section 301 with respect to such Securities and upon such terms as may be specified as contemplated by
Section 301 with respect to such Securities.

ARTICLE FOUR

REDEMPTION OF SECURITIES

SECTION 401. APPLICABILITY OF ARTICLE.

Securities of any series, or any Tranche thereof, which are redeemable before their Stated Maturity shall be redeemable in accordance with their terms and (except as otherwise specified as contemplated by Section 301 for Securities of such series or Tranche) in accordance with this Article.

SECTION 402. ELECTION TO REDEEM; NOTICE TO TRUSTEE.

The election of the Company to redeem any Securities shall be evidenced by a Board Resolution or an Officer's Certificate. The Company shall, at least 45 days prior to the Redemption Date fixed by the Company (unless a shorter notice shall be satisfactory to the Trustee), notify the Trustee in writing of such Redemption Date and of the principal amount of such Securities to be redeemed. In the case of any redemption of Securities (a) prior to the expiration of any restriction on such redemption provided in the terms of such Securities or elsewhere in this Indenture or (b) pursuant to an election of the Company which is subject to a condition specified in the terms of such Securities, the Company shall furnish the Trustee with an Officer's Certificate evidencing compliance with such restriction or condition.

SECTION 403. SELECTION OF SECURITIES TO BE REDEEMED.

If less than all the Securities of any series, or any Tranche thereof, are to be redeemed, the particular Securities to be redeemed shall be selected by the Security Registrar from the Outstanding Securities of such series or Tranche not previously called for redemption, by such method as shall be provided for any particular series or Tranche, or, in the absence of any such provision, by such method of random selection as the Security Registrar shall deem fair and appropriate and which may, in any case, provide for the selection for redemption of portions (equal to the minimum authorized denomination for Securities of such series or Tranche or any integral multiple thereof) of the principal amount of Securities of such series or Tranche of a denomination

-22-

larger than the minimum authorized denomination for Securities of such series or Tranche; provided, however, that if, as indicated in an Officer's Certificate, the Company shall have offered to purchase all or any principal amount of the Securities then Outstanding of any series, or any Tranche thereof, and less than all of such Securities as to which such offer was made shall have been tendered to the Company for such purchase, the Security Registrar, if so directed by Company Order, shall select for redemption all or any principal amount of such Securities which have not been so tendered.

The Security Registrar shall promptly notify the Company and the Trustee in writing of the Securities selected for redemption and, in the case of any Securities selected to be redeemed in part, the principal amount thereof to be redeemed.

For all purposes of this Indenture, unless the context otherwise requires, all provisions relating to the redemption of Securities shall relate, in the case of any Securities redeemed or to be redeemed only in part, to the portion of the principal amount of such Securities which has been or is to be redeemed.

SECTION 404. NOTICE OF REDEMPTION.

Notice of redemption shall be given in the manner provided in Section 106 to the Holders of the Securities to be redeemed not less than 30 nor more than 60 days prior to the Redemption Date.

All notices of redemption shall state:

(a) the Redemption Date,

(b) the Redemption Price,

(c) if less than all the Securities of any series or Tranche are to be redeemed, the identification of the particular Securities to be redeemed and the portion of the principal amount of any Security to be redeemed in part,

(d) that on the Redemption Date the Redemption Price, together with accrued interest, if any, to the Redemption Date, will become due and payable upon each such Security to be redeemed and, if applicable, that interest thereon will cease to accrue on and after said date,

(e) the place or places where such Securities are to be surrendered for payment of the Redemption Price and accrued interest, if any, unless it shall have been specified as contemplated by Section 301 with respect to such Securities that such surrender shall not be required,

(f) that the redemption is for a sinking or other fund, if such is the case, and

(g) such other matters as the Company shall deem desirable or appropriate.

Unless otherwise specified with respect to any Securities in accordance with Section 301, with respect to any notice of redemption of Securities at the election of the Company, unless, upon the giving of such notice, such Securities shall be deemed to have been paid in accordance with Section 701, such notice may state that such redemption shall be conditional upon the receipt by the Paying Agent or Agents for such Securities, on or prior to the date fixed for such redemption, of money sufficient to pay the principal of and premium, if any, and interest, if any, on such Securities and that if such money shall not have been so received such notice shall be of no force or effect and the Company shall not be required to redeem such Securities. In the event that such notice of redemption contains such a condition and such money is not so received, the redemption shall not be made and within a reasonable time thereafter notice shall be given, in the manner in which the notice of redemption was given, that such money was not so received and such redemption was not required to be made, and the Paying Agent or Agents for the Securities otherwise to have been redeemed shall

-23-

promptly return to the Holders thereof any of such Securities which had been surrendered for payment upon such redemption.

Notice of redemption of Securities to be redeemed at the election of the Company, and any notice of non-satisfaction of a condition for redemption as aforesaid, shall be given by the Company or, at the Company's request, by the Security Registrar in the name and at the expense of the Company. Notice of mandatory redemption of Securities shall be given by the Security Registrar in the name and at the expense of the Company.

SECTION 405. SECURITIES PAYABLE ON REDEMPTION DATE.

Notice of redemption having been given as aforesaid, and the conditions, if any, set forth in such notice having been satisfied, the Securities or portions thereof so to be redeemed shall, on the Redemption Date, become due and payable at the Redemption Price therein specified, and from and after such date (unless, in the case of an unconditional notice of redemption, the Company shall default in the payment of the Redemption Price and accrued interest, if any) such Securities or portions thereof, if interest-bearing, shall cease to bear interest. Upon surrender of any such Security for redemption in accordance with such notice, such Security or portion thereof shall be paid by the Company at the Redemption Price, together with accrued interest, if any, to the Redemption Date; provided, however, that no such surrender shall be a condition to such payment if so specified as contemplated by Section 301 with respect to such Security; and provided, further, that except as otherwise specified as contemplated by Section 301 with respect to such Security, any installment of interest on any Security the Stated Maturity of which installment is on or prior to the Redemption Date shall be payable to the Holder of such Security, or one or more Predecessor Securities, registered as such at the close of business on the related Regular Record Date according to the terms of such Security and subject to the provisions of Section 307.

SECTION 406. SECURITIES REDEEMED IN PART.

Upon the surrender of any Security which is to be redeemed only in part at a Place of Payment therefor (with, if the Company or the Trustee so requires, due endorsement by, or a written instrument of transfer in form satisfactory to the Company and the Trustee duly executed by, the Holder thereof or his attorney duly authorized in writing), the Company shall execute, and the Trustee shall authenticate and deliver to the Holder of such Security, without service charge, a new Security or Securities of the same series and Tranche, of any authorized denomination requested by such Holder and of like tenor and in aggregate principal amount equal to and in exchange for the unredeemed portion of the principal of the Security so surrendered.

ARTICLE FIVE

SECTION 501. APPLICABILITY OF ARTICLE.

The provisions of this Article shall be applicable to any sinking fund for the retirement of the Securities of any series, or any Tranche thereof, except as otherwise specified as contemplated by Section 301 for Securities of such series or Tranche.

The minimum amount of any sinking fund payment provided for by the terms of Securities of any series, or any Tranche thereof, is herein referred to as a "mandatory sinking fund payment", and any payment in excess of such minimum amount provided for by the terms of Securities of any series, or any Tranche thereof, is herein referred to as an "optional sinking fund payment". If provided for by the terms of Securities of any series, or any Tranche thereof, the cash amount of any sinking fund payment may be subject to reduction as provided in Section 502. Each sinking fund payment shall be applied to the redemption of

-24-

Securities of the series or Tranche in respect of which it was made as provided for by the terms of such Securities.

SECTION 502. SATISFACTION OF SINKING FUND PAYMENTS WITH SECURITIES.

The Company (a) may deliver to the Trustee Outstanding Securities (other than any previously called for redemption) of a series or Tranche in respect of which a mandatory sinking fund payment is to be made and (b) may apply as a credit Securities of such series or Tranche which have been (1) redeemed either at the election of the Company pursuant to the terms of such Securities or through the application of permitted optional sinking fund payments pursuant to the terms of such Securities or (2) repurchased by the Company in the open market, by tender offer or otherwise, in each case in satisfaction of all or any part of such mandatory sinking fund payment; provided, however, that no Securities shall be applied in satisfaction of a mandatory sinking fund payment if such Securities shall have been previously so applied. Securities so applied shall be received and credited for such purpose by the Trustee at the Redemption Price specified in such Securities for redemption through operation of the sinking fund and the amount of such mandatory sinking fund payment shall be reduced accordingly.

SECTION 503. REDEMPTION OF SECURITIES FOR SINKING FUND.

Not less than 45 days prior to each sinking fund payment date for the Securities of any series, or any Tranche thereof, the Company shall deliver to the Trustee an Officer's Certificate specifying:

(a) the amount of the next succeeding mandatory sinking fund payment for such series or Tranche;

(b) the amount, if any, of the optional sinking fund payment to be made together with such mandatory sinking fund payment;

(c) the aggregate sinking fund payment;

(d) the portion, if any, of such aggregate sinking fund payment which is to be satisfied by the payment of cash;

(e) the portion, if any, of such aggregate sinking fund payment which is to be satisfied by delivering and crediting Securities of such series or Tranche pursuant to Section 502 and stating the basis for such credit and that such Securities have not previously been so credited, and the Company shall also deliver to the Trustee any Securities to be so delivered. If the Company shall not deliver such Officer's Certificate, the next succeeding sinking fund payment for such series or Tranche shall be made entirely in cash in the amount of the mandatory sinking fund payment. Not less than 40 days before each such sinking fund payment date the Trustee shall select the Securities to be redeemed upon such sinking fund payment date in the manner specified in Section 403 and cause notice of the redemption thereof to be given in the name of and at the expense of the Company in the manner provided in Section 404. Such notice having been duly given, the redemption of such Securities shall be made upon the terms and in the manner stated in Sections 405 and 406.

The Company shall give prompt written notice to the Trustee of the location, and any change in the location, of each such office or agency and prompt notice to the Holders of any such change in the manner specified in Section 106.

The Company shall give prompt written notice to the Trustee, and prompt notice to the Holders in the manner specified in Section 106, of any such designation or rescission and of any change in the location of any such other office or agency.

Anything herein to the contrary notwithstanding, any office or agency required by this Section may be maintained at an office of the Company, in which event the Company shall perform all functions to be performed at such office or agency.

SECTION 603. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST.

If the Company shall at any time act as its own Paying Agent with respect to the Securities of any series, or any Tranche thereof, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on any of such Securities, segregate and hold in trust for the benefit of the Persons entitled thereto a sum sufficient to pay the principal and premium or interest so becoming due until such sums shall be paid to such Persons or otherwise disposed of as herein provided. The Company shall promptly notify the Trustee of any failure by the Company (or any other obligor on such Securities) to make any payment of principal of or premium, if any, or interest, if any, on such Securities.

Whenever the Company shall have one or more Paying Agents for the Securities of any series, or any Tranche thereof, it shall, on or before each due date of the principal of and premium, if any, and interest, if any, on such Securities, deposit with such Paying Agents sums sufficient (without duplication) to pay the principal and premium or interest so becoming due, such sums to be held in trust for the benefit of the Persons entitled to such principal, premium or interest, and (unless such Paying Agent is the Trustee) the Company shall promptly notify the Trustee of any failure by it so to act.

The Company shall cause each Paying Agent for the Securities of any series, or any Tranche thereof, other than the Company or the Trustee, to execute and deliver to the Trustee an instrument in which such Paying Agent shall agree with the Trustee, subject to the provisions of this Section, that such Paying Agent shall:

The Company may at any time pay, or by Company Order direct any Paying Agent to pay, to the Trustee all sums held in trust by the Company or such Paying Agent, such sums to be held by the Trustee upon the same trusts as those upon which such sums were held by the Company or such Paying Agent and, if so stated in a Company Order delivered to the Trustee, in accordance with the provisions of Article Seven; and, upon such payment by any Paying Agent to the Trustee, such Paying Agent shall be released from all further liability with respect to such money.

Any money deposited with the Trustee or any Paying Agent, or then held by the Company, in trust for the payment of the principal of and premium, if any, or interest, if any, on any Security and remaining unclaimed for two years after such principal and premium, if any, or interest, if any, has become due and payable shall be paid to the Company on Company Request, or, if then held by the Company, shall be discharged from such trust; and, upon such payment or discharge, the Holder of such Security shall, as an unsecured general creditor and not as a Holder of an Outstanding Security, look only to the Company for payment of the amount so due and payable and remaining unpaid, and all liability of the Trustee or such Paying Agent with respect to such trust money, and all liability of the Company as trustee thereof, shall thereupon cease; provided, however, that the Trustee or such Paying Agent, before being required to make any such payment to the Company, may at the expense of the Company cause to be mailed, on one occasion only, notice to such Holder that such money remains unclaimed and that, after a date specified therein, which shall not be less than 30 days from the date of such mailing, any unclaimed balance of such money then remaining will be paid to the Company.

SECTION 606. ANNUAL OFFICER'S CERTIFICATE AS TO COMPLIANCE.

Not later than October 1 in each year, commencing October 1, 2004, the Company shall deliver to the Trustee an Officer's Certificate which need not comply with Section 102, executed by the principal executive officer, the principal financial officer or the principal accounting officer of the Company, as to such officer's knowledge of the Company's compliance with all conditions and covenants under this Indenture, such

-27-

compliance to be determined without regard to any period of grace or requirement of notice under this Indenture.

SECTION 607. WAIVER OF CERTAIN COVENANTS.

The Company may omit in any particular instance to comply with any term, provision or condition set forth in (a) Section 602 or any additional covenant or restriction specified with respect to the Securities of any series, or any Tranche thereof, as contemplated by Section 301 if before the time for such compliance the Holders of at least a majority in aggregate principal amount of the Outstanding Securities of all series and Tranches with respect to which compliance with Section 602 or such additional covenant or restriction is to be omitted, considered as one class, shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition and (b) Section 604, 605 or Article Eleven if before the time for such compliance the Holders of at least a majority in principal amount of Securities Outstanding under this Indenture shall, by Act of such Holders, either waive such compliance in such instance or generally waive compliance with such term, provision or condition; but, in the case of (a) or (b), no such waiver shall extend to or affect such term, provision or condition except to the extent so expressly waived, and, until such waiver shall become effective, the obligations of the Company and the duties of the Trustee in respect of any such term, provision or condition shall remain in full force and effect.

SECTION 608. LIMITATIONS ON LIENS.

So long as there remain outstanding any Securities of any series to which this Section 608 applies under the terms of the series, the Company shall not, and will not permit any subsidiary to, create or suffer to be created or to exist any Lien on any of its properties or assets now owned or hereinafter acquired to secure any indebtedness, without making effective provision whereby the Securities (together with, if the Company shall so determine, any other debt of the Company or any subsidiary then existing or thereafter created that is not subordinate to such Securities) of such series shall be equally and ratably secured with (or prior to) any and all such indebtedness and with any other indebtedness similarly entitled to be equally and ratably secured. However, this restriction shall not apply to or prevent the creation or existence of:

(a) the Liens of the Mortgages or any indenture supplemental to any thereof subjecting any property to the Lien thereof or confirming the Lien thereof upon any property, whether now owned or hereafter acquired;

(b) Liens on property existing at the time of acquisition or construction of such property (or created within one year after completion of such acquisition or construction), whether by purchase, merger,construction or otherwise (or on the property of a subsidiary at the date it became a subsidiary), or to secure the payment of all or any part of the purchase price or construction cost thereof, including the extension of any such Liens to repairs, renewals, replacements, substitutions, betterments, additions, extensions and improvements then or thereafter made on the property subject thereto;

(c) any extensions, renewals or replacements (or successive extensions, renewals or replacements), in whole or in part of Liens permitted by the foregoing clauses (a) and (b);

SATISFACTION AND DISCHARGE

SECTION 701. SATISFACTION AND DISCHARGE OF SECURITIES.

Any Security or Securities, or any portion of the principal amount thereof, shall be deemed to have been paid for all purposes of this Indenture, and the entire indebtedness of the Company in respect thereof shall be deemed to have been satisfied and discharged, if there shall have been irrevocably deposited with the Trustee or any Paying Agent (other than the Company), in trust:

(a) money in an amount which shall be sufficient, or

(b) in the case of a deposit made prior to the Maturity of such Securities or portions thereof, Eligible Obligations, which shall not contain provisions permitting the redemption or other prepayment thereof at the option of the issuer thereof, the principal of and the interest on which when due, without any regard to reinvestment thereof, will provide moneys which, together with the money, if any, deposited with or held by the Trustee or such Paying Agent, shall be sufficient, or

(c) a combination of (a) or (b) which shall be sufficient,

to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Securities or portions thereof on or prior to Maturity; provided, however, that in the case of the provision for payment or redemption of less than all the Securities of any series or Tranche, such Securities or portions thereof shall have been selected by the Security Registrar as provided herein and, in the case of a redemption, the notice requisite to the validity of such redemption shall have been given or irrevocable authority shall have been given by the Company to the Trustee to give such notice, under arrangements satisfactory to the Trustee; and provided, further, that the Company shall have delivered to the Trustee and such Paying Agent:

(x) if such deposit shall have been made prior to the Maturity of such Securities, a Company Order stating that the money and Eligible Obligations deposited in accordance with this Section shall be held in trust, as provided in Section 703;

(y) if Eligible Obligations shall have been deposited, an Opinion of Counsel that the obligations so deposited constitute Eligible Obligations and do not contain provisions permitting the redemption or other prepayment at the option of the issuer thereof, and an opinion of an independent public accountant of nationally recognized standing, selected by the Company, to the effect that the requirements set forth in clause (b) above have been satisfied; and

(z) if such deposit shall have been made prior to the Maturity of such Securities, an Officer's Certificate stating the Company's intention that, upon delivery of such Officer's Certificate, its indebtedness in respect of such Securities or portions thereof will have been satisfied and discharged as contemplated in this Section.

Upon the deposit of money or Eligible Obligations, or both, in accordance with this Section, together with the documents required by clauses (x), (y) and
(z) above, the Trustee shall, upon receipt of a Company Request, acknowledge in writing that the Security or Securities or portions thereof with respect to which such deposit was made are deemed to have been paid for all purposes of this Indenture and that the entire indebtedness of the Company in respect thereof has been satisfied and discharged as contemplated in this Section. In the event that all of the conditions set forth in the preceding paragraph shall have been satisfied in respect of any Securities or portions thereof except that, for any reason, the Officer's Certificate specified in clause (z) shall not have been delivered, such Securities or portions thereof shall nevertheless be deemed to

-29-

have been paid for all purposes of this Indenture, and the Holders of such Securities or portions thereof shall nevertheless be no longer entitled to the benefits of this Indenture or of any of the covenants of the Company under Article Six (except the covenants contained in Sections 602, 603 and 604) or any other covenants made in respect of such Securities or portions thereof as contemplated by Section 301, but the indebtedness of the Company in respect of such Securities or portions thereof shall not be deemed to have been satisfied and discharged prior to Maturity for any other purpose, and the Holders of such Securities or portions thereof shall continue to be entitled to look to the Company for payment of the indebtedness represented thereby; and, upon Company Request, the Trustee shall acknowledge in writing that such Securities or portions thereof are deemed to have been paid for all purposes of this Indenture.

If payment at Stated Maturity of less than all of the Securities of any series, or any Tranche thereof, is to be provided for in the manner and with the effect provided in this Section, the Security Registrar shall select such Securities, or portions of principal amount thereof, in the manner specified by
Section 403 for selection for redemption of less than all the Securities of a series or Tranche.

In the event that Securities which shall be deemed to have been paid for purposes of this Indenture, and, if such is the case, in respect of which the Company's indebtedness shall have been satisfied and discharged, all as provided in this Section do not mature and are not to be redeemed within the sixty (60) day period commencing with the date of the deposit of moneys or Eligible Obligations, as aforesaid, the Company shall, as promptly as practicable, give a notice, in the same manner as a notice of redemption with respect to such Securities, to the Holders of such Securities to the effect that such deposit has been made and the effect thereof.

Notwithstanding that any Securities shall be deemed to have been paid for purposes of this Indenture, as aforesaid, the obligations of the Company and the Trustee in respect of such Securities under Sections 304, 305, 306, 403, 404, 406, 503 (as to notice of redemption), 602, 603, 907, 909, 910 and 915 and this Article Seven shall survive.

The Company shall pay, and shall indemnify the Trustee or any Paying Agent with which Eligible Obligations shall have been deposited as provided in this
Section against, any tax, fee or other charge imposed on or assessed against such Eligible Obligations or the principal or interest received in respect of such Eligible Obligations, including, but not limited to, any such tax payable by any entity deemed, for tax purposes, to have been created as a result of such deposit.

Anything herein to the contrary notwithstanding, (a) if, at any time after a Security would be deemed to have been paid for purposes of this Indenture, and, if such is the case, the Company's indebtedness in respect thereof would be deemed to have been satisfied or discharged, pursuant to this Section (without regard to the provisions of this paragraph), the Trustee or any Paying Agent, as the case may be, shall be required to return the money or Eligible Obligations, or combination thereof, deposited with it as aforesaid to the Company or its representative under any applicable Federal or State bankruptcy, insolvency or other similar law, such Security shall thereupon be deemed retroactively not to have been paid and any satisfaction and discharge of the Company's indebtedness in respect thereof shall retroactively be deemed not to have been effected, and such Security shall be deemed to remain Outstanding and (b) any satisfaction and discharge of the Company's indebtedness in respect of any Security shall be subject to the provisions of the last paragraph of Section 603.

SECTION 702. SATISFACTION AND DISCHARGE OF INDENTURE.

This Indenture shall upon Company Request cease to be of further effect (except as hereinafter expressly provided), and the Trustee, at the expense of the Company, shall execute proper instruments acknowledging satisfaction and discharge of this Indenture, when

(a) no Securities remain Outstanding hereunder; and

-30-

(b) the Company has paid or caused to be paid all other sums payable hereunder by the Company;

provided, however, that if, in accordance with the last paragraph of Section 701, any Security, previously deemed to have been paid for purposes of this Indenture, shall be deemed retroactively not to have been so paid, this Indenture shall thereupon be deemed retroactively not to have been satisfied and discharged, as aforesaid, and to remain in full force and effect, and the Company shall execute and deliver such instruments as the Trustee shall reasonably request to evidence and acknowledge the same.

Notwithstanding the satisfaction and discharge of this Indenture as aforesaid, the obligations of the Company and the Trustee under Sections 304, 305, 306, 403, 404, 406, 503 (as to notice of redemption), 602, 603, 907, 909, 910 and 915 and this Article Seven shall survive.

Upon satisfaction and discharge of this Indenture as provided in this Section, the Trustee shall assign, transfer and turn over to the Company, subject to the lien provided by Section 907, any and all money, securities and other property then held by the Trustee for the benefit of the Holders of the Securities other than money and Eligible Obligations held by the Trustee pursuant to Section 703.

SECTION 703. APPLICATION OF TRUST MONEY.

Neither the Eligible Obligations nor the money deposited pursuant to
Section 701, nor the principal or interest payments on any such Eligible Obligations, shall be withdrawn or used for any purpose other than, and such Eligible Obligations and money deposited and the principal and interest payments on any such Eligible Obligations shall be held in trust for, the payment of the principal of and premium, if any, and interest, if any, on the Securities or portions of principal amount thereof in respect of which such deposit was made, all subject, however, to the provisions of Section 603; provided, however, that, so long as there shall not have occurred and be continuing an Event of Default, any cash received from such principal or interest payments on such Eligible Obligations, if not then needed for such purpose, shall, to the extent practicable, be invested in Eligible Obligations of the type described in clause
(b) in the first paragraph of Section 701 maturing at such times and in such amounts as shall be sufficient, together with any other moneys and the principal of and interest on any other Eligible Obligations then held by the Trustee, to pay when due the principal of and premium, if any, and interest, if any, due and to become due on such Securities or portions thereof on and prior to the Maturity thereof, and interest earned from such reinvestment shall be paid over to the Company as received, free and clear of any trust, lien or pledge under this Indenture except the lien provided by Section 907; and provided, further, that, so long as there shall not have occurred and be continuing an Event of Default, any moneys held in accordance with this Section on the Maturity of all such Securities in excess of the amount required to pay the principal of and premium, if any, and interest, if any, then due on such Securities shall be paid over to the Company free and clear of any trust, lien or pledge under this Indenture except the lien provided by Section 907; and provided, further, that if an Event of Default shall have occurred and be continuing, moneys to be paid over to the Company pursuant to this Section shall be held until such Event of Default shall have been waived or cured.

ARTICLE EIGHT

EVENTS OF DEFAULT; REMEDIES

SECTION 801. EVENTS OF DEFAULT.

"Event of Default", wherever used herein with respect to Securities of any series, means any one of the following events:

(a) failure to pay interest, if any, on any Security of such series within sixty (60) days after the same becomes due and payable; provided, however, that a valid extension of the interest

-31-

payment period by the Company as contemplated in Section 312 of this Indenture shall not constitute a failure to pay interest for this purpose; or

(b) failure to pay the principal of or premium, if any, on any Security of such series within ten (10) days after its Maturity; or

(c) failure to perform, or breach of, any covenant or warranty of the Company in this Indenture (other than a covenant or warranty a default in the performance of which or breach of which is elsewhere in this Section specifically dealt with or which has expressly been included in this Indenture solely for the benefit of one or more series of Securities other than such series) for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee, or to the Company and the Trustee by the Holders of at least 33% in principal amount of the Outstanding Securities of such series, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a "Notice of Default" hereunder, unless the Trustee, or the Trustee and the Holders of a principal amount of Securities of such series not less than the principal amount of Securities the Holders of which gave such notice, as the case may be, shall agree in writing to an extension of such period prior to its expiration; provided, however, that the Trustee, or the Trustee and the Holders of such principal amount of Securities of such series, as the case may be, shall be deemed to have agreed to an extension of such period if corrective action is initiated by the Company within such period and is being diligently pursued; or

(d) the entry by a court having jurisdiction in the premises of (1) a decree or order for relief in respect of the Company in an involuntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or (2) a decree or order adjudging the Company a bankrupt or insolvent, or approving as properly filed a petition by one or more Persons other than the Company seeking reorganization, arrangement, adjustment or composition of or in respect of the Company under any applicable Federal or State law, or appointing a custodian, receiver, liquidator, assignee, trustee, sequestrator or other similar official for the Company or for any substantial part of its property, or ordering the winding up or liquidation of its affairs, and any such decree or order for relief or any such other decree or order shall have remained unstayed and in effect for a period of 90 consecutive days; or

(e) the commencement by the Company of a voluntary case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or of any other case or proceeding to be adjudicated a bankrupt or insolvent, or the consent by it to the entry of a decree or order for relief in respect of the Company in a case or proceeding under any applicable Federal or State bankruptcy, insolvency, reorganization or other similar law or to the commencement of any bankruptcy or insolvency case or proceeding against it, or the filing by it of a petition or answer or consent seeking reorganization or relief under any applicable Federal or State law, or the consent by it to the filing of such petition or to the appointment of or taking possession by a custodian, receiver, liquidator, assignee, trustee, sequestrator or similar official of the Company or of any substantial part of its property, or the making by it of an assignment for the benefit of creditors, or the admission by it in writing of its inability to pay its debts generally as they become due, or the authorization of such action by the Board of Directors; or

(f) any other Event of Default specified with respect to Securities of such series.

SECTION 802. ACCELERATION OF MATURITY; RESCISSION AND ANNULMENT.

If an Event of Default shall have occurred and be continuing with respect to Securities of any series at the time Outstanding, then in every such case the Trustee or the Holders of not less than 33% in principal amount of the Outstanding Securities of such series may declare the principal amount (or, if any of the Securities of such series are Discount Securities, such portion of the principal amount of such Securities as

-32-

may be specified in the terms thereof as contemplated by Section 301) of all of the Securities of such series to be due and payable immediately, by a notice in writing to the Company (and to the Trustee if given by Holders), and upon receipt by the Company of notice of such declaration such principal amount (or specified amount) shall become immediately due and payable; provided, however, that if an Event of Default shall have occurred and be continuing with respect to more than one series of Securities, the Trustee or the Holders of not less than 33% in aggregate principal amount of the Outstanding Securities of all such series, considered as one class (and not the Holders of the Securities of any one of such series), may make such declaration of acceleration.

At any time after such a declaration of acceleration with respect to Securities of any series shall have been made and before a judgment or decree for payment of the money due shall have been obtained by the Trustee as hereinafter in this Article provided, the Event or Events of Default giving rise to such declaration of acceleration shall, without further act, be deemed to have been waived, and such declaration and its consequences shall, without further act, be deemed to have been rescinded and annulled, if

(a) the Company shall have paid or deposited with the Trustee a sum sufficient to pay

(1) all overdue interest on all Securities of such series;

(2) the principal of and premium, if any, on any Securities of such series which have become due otherwise than by such declaration of acceleration and interest thereon at the rate or rates prescribed therefor in such Securities;

(3) to the extent that payment of such interest is lawful, interest upon overdue interest at the rate or rates prescribed therefor in such Securities;

(4) all amounts due to the Trustee under Section 907; and

(b) any other Event or Events of Default with respect to Securities of such series, other than the non-payment of the principal of Securities of such series which shall have become due solely by such declaration of acceleration, shall have been cured or waived as provided in Section 813.

No such rescission shall affect any subsequent Event of Default or impair any right consequent thereon.

SECTION 803. COLLECTION OF INDEBTEDNESS AND SUITS FOR ENFORCEMENT BY TRUSTEE.

If an Event of Default described in clause (a) or (b) of Section 801 shall have occurred and be continuing, the Company shall, upon demand of the Trustee, pay to it, for the benefit of the Holders of the Securities of the series with respect to which such Event of Default shall have occurred, the whole amount then due and payable on such Securities for principal and premium, if any, and interest, if any, and, to the extent permitted by law, interest on premium, if any, and on any overdue principal and interest, at the rate or rates prescribed therefor in such Securities, and, in addition thereto, such further amount as shall be sufficient to cover any amounts due to the Trustee under Section 907.

If the Company shall fail to pay such amounts forthwith upon such demand, the Trustee, in its own name and as trustee of an express trust, may institute a judicial proceeding for the collection of the sums so due and unpaid, may prosecute such proceeding to judgment or final decree and may enforce the same against the Company or any other obligor upon such Securities and collect the moneys adjudged or decreed to be payable in the manner provided by law out of the property of the Company or any other obligor upon such Securities, wherever situated.

If an Event of Default with respect to Securities of any series shall have occurred and be continuing, the Trustee may in its discretion proceed to protect and enforce its rights and the rights of the Holders of

-33-

Securities of such series by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any such rights, whether for the specific enforcement of any covenant or agreement in this Indenture or in aid of the exercise of any power granted herein, or to enforce any other proper remedy.

SECTION 804. TRUSTEE MAY FILE PROOFS OF CLAIM.

In case of the pendency of any receivership, insolvency, liquidation, bankruptcy, reorganization, arrangement, adjustment, composition or other judicial proceeding relative to the Company or any other obligor upon the Securities or the property of the Company or of such other obligor or their creditors, the Trustee (irrespective of whether the principal of the Securities shall then be due and payable as therein expressed or by declaration or otherwise and irrespective of whether the Trustee shall have made any demand on the Company for the payment of overdue principal or interest) shall be entitled and empowered, by intervention in such proceeding or otherwise,

(a) to file and prove a claim for the whole amount of principal, premium, if any, and interest, if any, owing and unpaid in respect of the Securities and to file such other papers or documents as may be necessary or advisable in order to have the claims of the Trustee (including any claim for amounts due to the Trustee under Section 907) and of the Holders allowed in such judicial proceeding, and

(b) to collect and receive any moneys or other property payable or deliverable on any such claims and to distribute the same;

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or other similar official in any such judicial proceeding is hereby authorized by each Holder to make such payments to the Trustee and, in the event that the Trustee shall consent to the making of such payments directly to the Holders, to pay to the Trustee any amounts due it under Section 907.

Nothing herein contained shall be deemed to authorize the Trustee to authorize or consent to or accept or adopt on behalf of any Holder any plan of reorganization, arrangement, adjustment or composition affecting the Securities or the rights of any Holder thereof or to authorize the Trustee to vote in respect of the claim of any Holder in any such proceeding.

No Holder shall have any right to institute any proceeding, judicial or otherwise, with respect to this Indenture, or for the appointment of a receiver or trustee, or for any other remedy hereunder, unless:

(b) the Holders of not less than a majority in aggregate principal amount of the Outstanding Securities of all series in respect of which an Event of Default shall have occurred and be continuing, considered as one class, shall have made written request to the Trustee to institute proceedings in respect of such Event of Default in its own name as Trustee hereunder;

SECTION 808. UNCONDITIONAL RIGHT OF HOLDERS TO RECEIVE PRINCIPAL, PREMIUM AND

INTEREST.

Notwithstanding any other provision in this Indenture, the Holder of any Security shall have the right, which is absolute and unconditional, to receive payment of the principal of and premium, if any, and (subject to Section 307 and 312) interest, if any, on such Security on the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on the Redemption Date) and to institute suit for the enforcement of any such payment, and such rights shall not be impaired without the consent of such Holder.

Except as otherwise provided in the last paragraph of Section 306, no right or remedy herein conferred upon or reserved to the Trustee or to the Holders is intended to be exclusive of any other right or remedy, and every right and remedy shall, to the extent permitted by law, be cumulative and in addition to every other right and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder, or otherwise, shall not prevent the concurrent assertion or employment of any other appropriate right or remedy.

SECTION 811. DELAY OR OMISSION NOT WAIVER.

No delay or omission of the Trustee or of any Holder to exercise any right or remedy accruing upon any Event of Default shall impair any such right or remedy or constitute a waiver of any such Event of Default or an acquiescence therein. Every right and remedy given by this Article or by law to the Trustee or to the Holders may be exercised from time to time, and as often as may be deemed expedient, by the Trustee or by the Holders, as the case may be.

SECTION 812. CONTROL BY HOLDERS OF SECURITIES.

If an Event of Default shall have occurred and be continuing in respect of a series of Securities, the Holders of a majority in principal amount of the Outstanding Securities of such series shall have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Trustee, or exercising any trust or power conferred on the Trustee, with respect to the Securities of such series; provided, however, that if an Event of Default shall have occurred and be continuing with respect to more than one series of Securities, the Holders of a majority in aggregate principal amount of the Outstanding Securities of all such series, considered as one class, shall have the right to make such direction, and not the Holders of the Securities of any one of such series; and provided, further, that

(a) such direction shall not be in conflict with any rule of law or with this Indenture, and could not involve the Trustee in personal liability in circumstances where indemnity would not, in the Trustee's sole discretion, be adequate, and

(b) the Trustee may take any other action deemed proper by the Trustee which is not inconsistent with such direction.

SECTION 813. WAIVER OF PAST DEFAULTS.

(b) in respect of a covenant or provision hereof which under Section 1202 cannot be modified or amended without the consent of the Holder of each Outstanding Security of such series affected.

-36-

Upon any such waiver, such default shall cease to exist, and any and all Events of Default arising therefrom shall be deemed to have been cured, for every purpose of this Indenture; but no such waiver shall extend to any subsequent or other default or impair any right consequent thereon.

SECTION 814. UNDERTAKING FOR COSTS.

The Company and the Trustee agree, and each Holder by his acceptance thereof shall be deemed to have agreed, that any court may in its discretion require, in any suit for the enforcement of any right or remedy under this Indenture, or in any suit against the Trustee for any action taken, suffered or omitted by it as Trustee, the filing by any party litigant in such suit of an undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys' fees, against any party litigant in such suit, having due regard to the merits and good faith of the claims or defenses made by such party litigant; but the provisions of this Section shall not apply to any suit instituted by the Company, to any suit instituted by the Trustee, to any suit instituted by any Holder, or group of Holders, holding in the aggregate more than 10% in aggregate principal amount of the Outstanding Securities of all series in respect of which such suit may be brought, considered as one class, or to any suit instituted by any Holder for the enforcement of the payment of the principal of or premium, if any, or interest, if any, on any Security on or after the Stated Maturity or Maturities expressed in such Security (or, in the case of redemption, on or after the Redemption Date).

SECTION 815. WAIVER OF STAY OR EXTENSION LAWS.

The Company covenants (to the extent that it may lawfully do so) that it will not at any time insist upon, or plead, or in any manner whatsoever claim or take the benefit or advantage of, any stay or extension law wherever enacted, now or at any time hereafter in force, which may affect the covenants or the performance of this Indenture; and the Company (to the extent that it may lawfully do so) hereby expressly waives all benefit or advantage of any such law and covenants that it will not hinder, delay or impede the execution of any power herein granted to the Trustee, but will suffer and permit the execution of every such power as though no such law had been enacted.

THE TRUSTEE

SECTION 901. CERTAIN DUTIES AND RESPONSIBILITIES.

(a) Except during the continuance of an Event of Default with respect to Securities of any series,

(1) the Trustee undertakes to perform, with respect to Securities of such series, such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants or obligations shall be read into this Indenture against the Trustee; and

(2) in the absence of bad faith on its part, the Trustee may, with respect to Securities of such series, conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but in the case of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this Indenture.

(b) In case an Event of Default with respect to Securities of any series shall have occurred and be continuing, the Trustee shall exercise, with respect to Securities of such series, such

of the rights and powers vested in it by this Indenture, and use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

(c) No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act, or its own wilful misconduct, except that

(1) this clause (c) shall not be construed to limit the effect of clause (a) of this Section;

(2) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer, unless it shall be proved that the Trustee was negligent in ascertaining the pertinent facts;

(4) no provision of this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur any financial liability in the performance of any of its duties hereunder, or in the exercise of any of its rights or powers, if it shall have reasonable grounds for believing that repayment of such funds or adequate indemnity against such risk or liability is not reasonably assured to it.

SECTION 902. NOTICE OF DEFAULTS.

The Trustee shall give notice of any default hereunder with respect to the Securities of any series to the Holders of Securities of such series in the manner and to the extent required to do so by the Trust Indenture Act, unless such default shall have been cured or waived; provided, however, that in the case of any default of the character specified in clause (c) of Section 801, no such notice to Holders shall be given until at least 75 days after the occurrence thereof.

(f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any resolution, certificate, statement, instrument, opinion, report, notice, request, direction, consent, order, bond, debenture, note, other evidence of indebtedness or other paper or document, but the Trustee, in its discretion, may make such further inquiry or investigation into such facts or matters as it may see fit, and, if the Trustee shall determine to make such further inquiry or investigation, it shall (subject to applicable legal requirements) be entitled to examine, during normal business hours, the books, records and premises of the Company, personally or by agent or attorney;

SECTION 904. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.

The recitals contained herein and in the Securities (except the Trustee's certificates of authentication) shall be taken as the statements of the Company, and neither the Trustee nor any Authenticating Agent assumes responsibility for their correctness.

Neither the Trustee nor any Authenticating Agent shall be accountable for the use or application by the Company of Securities or the proceeds thereof.

SECTION 905. MAY HOLD SECURITIES.

Each of the Trustee, any Authenticating Agent, any Paying Agent, any Security Registrar or any other agent of the Company or the Trustee, in its individual or any other capacity, may become the owner or pledgee of Securities and, subject to Sections 908 and 913, may otherwise deal with the Company with the same rights it would have if it were not the Trustee, Authenticating Agent, Paying Agent, Security Registrar or such other agent.

SECTION 906. MONEY HELD IN TRUST.

Money held by the Trustee in trust hereunder need not be segregated from other funds, except to the extent required by law. The Trustee shall be under no liability for interest on or investment of any money

received by it hereunder except as expressly provided herein or otherwise agreed with, and for the sole benefit of, the Company.

SECTION 907. COMPENSATION AND REIMBURSEMENT.

As security for the performance of the obligations of the Company under this Section, the Trustee shall have a lien prior to the Securities upon all property and funds held or collected by the Trustee as such other than property and funds held in trust under Section 703 (except as otherwise provided in
Section 703). "Trustee" for purposes of this Section shall include any predecessor Trustee; provided, however, that the negligence, wilful misconduct or bad faith of any Trustee hereunder shall not affect the rights of any other Trustee hereunder.

SECTION 908. DISQUALIFICATION; CONFLICTING INTERESTS.

and, in either case, qualified and eligible under this Article and the Trust Indenture Act. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of such supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section, it shall resign immediately in the manner and with the effect hereinafter specified in this Article.

SECTION 910. RESIGNATION AND REMOVAL; APPOINTMENT OF SUCCESSOR.

(a) No resignation or removal of the Trustee and no appointment of a successor Trustee pursuant to this Article shall become effective until the acceptance of appointment by the successor Trustee in accordance with the applicable requirements of Section 911.

(b) The Trustee may resign at any time with respect to the Securities of one or more series by giving written notice thereof to the Company. If the instrument of acceptance by a successor Trustee required by Section 911 shall not have been delivered to the Trustee within 30 days after the giving of such notice of resignation, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

(2) the Trustee shall cease to be eligible under Section 909 and shall fail to resign after written request therefor by the Company or by any such Holder, or

(3) the Trustee shall become incapable of acting or shall be adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property shall be appointed or any public officer shall take charge or control of the Trustee or of its property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, (A) the Company by a Board Resolution may remove the Trustee with respect to all Securities or (B) subject to Section 814, any Holder who has been a bona fide Holder for at least six months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the Trustee with respect to all Securities and the appointment of a successor Trustee or Trustees.

(e) If the Trustee shall resign, be removed or become incapable of acting, or if a vacancy shall occur in the office of Trustee for any cause (other than as contemplated in clause (B) in clause

-41-

(d) of this Section), with respect to the Securities of one or more series, the Company, by a Board Resolution, shall promptly appoint a successor Trustee or Trustees with respect to the Securities of that or those series (it being understood that any such successor Trustee may be appointed with respect to the Securities of one or more or all of such series and that at any time there shall be only one Trustee with respect to the Securities of any particular series) and shall comply with the applicable requirements of
Section 911. If, within one year after such resignation, removal or incapability, or the occurrence of such vacancy, a successor Trustee with respect to the Securities of any series shall be appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities of such series delivered to the Company and the retiring Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance of such appointment in accordance with the applicable requirements of Section 911, become the successor Trustee with respect to the Securities of such series and to that extent supersede the successor Trustee appointed by the Company. If no successor Trustee with respect to the Securities of any series shall have been so appointed by the Company or the Holders and accepted appointment in the manner required by Section 911, any Holder who has been a bona fide Holder of a Security of such series for at least six months may, on behalf of itself and all others similarly situated, petition any court of competent jurisdiction for the appointment of a successor Trustee with respect to the Securities of such series.

(f) So long as no event which is, or after notice or lapse of time, or both, would become, an Event of Default shall have occurred and be continuing, and except with respect to a Trustee appointed by Act of the Holders of a majority in principal amount of the Outstanding Securities pursuant to subsection (e) of this Section, if the Company shall have delivered to the Trustee (1) a Board Resolution appointing a successor Trustee, effective as of a date specified therein, and (2) an instrument of acceptance of such appointment, effective as of such date, by such successor Trustee in accordance with Section 911, the Trustee shall be deemed to have resigned as contemplated in subsection (b) of this Section, the successor Trustee shall be deemed to have been appointed by the Company pursuant to subsection (e) of this Section and such appointment shall be deemed to have been accepted as contemplated in Section 911, all as of such date, and all other provisions of this Section and Section 911 shall be applicable to such resignation, appointment and acceptance except to the extent inconsistent with this clause (f).

(g) The Company shall give notice of each resignation and each removal of the Trustee with respect to the Securities of any series and each appointment of a successor Trustee with respect to the Securities of any series by mailing written notice of such event by first-class mail, postage prepaid, to all Holders of Securities of such series as their names and addresses appear in the Security Register. Each notice shall include the name of the successor Trustee with respect to the Securities of such series and the address of its corporate trust office.

SECTION 911. ACCEPTANCE OF APPOINTMENT BY SUCCESSOR.

(a) In case of the appointment hereunder of a successor Trustee with respect to the Securities of all series, every such successor Trustee so appointed shall execute, acknowledge and deliver to the Company and to the retiring Trustee an instrument accepting such appointment, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee; but, on the request of the Company or the successor Trustee, such retiring Trustee shall, upon payment of all sums owed to it, execute and deliver an instrument transferring to such successor Trustee all the rights, powers and trusts of the retiring Trustee and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder.

(b) In case of the appointment hereunder of a successor Trustee with respect to the Securities of one or more (but not all) series, the Company, the retiring Trustee and each successor Trustee with respect to the Securities of such series shall execute and deliver an indenture

-42-

supplemental hereto wherein each successor Trustee shall accept such appointment and which (1) shall contain such provisions as shall be necessary or desirable to transfer and confirm to, and to vest in, each successor Trustee all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates, (2) if the retiring Trustee is not retiring with respect to all Securities, shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series as to which the retiring Trustee is not retiring shall continue to be vested in the retiring Trustee and (3) shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the trusts hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be trustee of a trust or trusts hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee; and upon the execution and delivery of such supplemental indenture the resignation or removal of the retiring Trustee shall become effective to the extent provided therein and each such successor Trustee, without any further act, shall become vested with all the rights, powers, trusts and duties of the retiring Trustee with respect to the Securities of that or those series to which the appointment of such successor Trustee relates; but, on request of the Company or any successor Trustee, such retiring Trustee, upon payment of all sums owed to it, shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee hereunder with respect to the Securities of that or those series to which the appointment of such successor Trustee relates.

(c) Upon request of any such successor Trustee, the Company shall execute any instruments which fully vest in and confirm to such successor Trustee all such rights, powers and trusts referred to in clause (a) or (b) of this Section, as the case may be.

(d) No successor Trustee shall accept its appointment unless at the time of such acceptance such successor Trustee shall be qualified and eligible under this Article.

SECTION 912. MERGER, CONVERSION, CONSOLIDATION OR SUCCESSION TO BUSINESS.

Any corporation into which the Trustee may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all the corporate trust business of the Trustee, shall be the successor of the Trustee hereunder, provided such corporation shall be otherwise qualified and eligible under this Article, without the execution or filing of any paper or any further act on the part of any of the parties hereto. In case any Securities shall have been authenticated, but not delivered, by the Trustee then in office, any successor by merger, conversion or consolidation to such authenticating Trustee may adopt such authentication and deliver the Securities so authenticated with the same effect as if such successor Trustee had itself authenticated such Securities.

SECTION 913. PREFERENTIAL COLLECTION OF CLAIMS AGAINST COMPANY.

If the Trustee shall be or become a creditor of the Company or any other obligor upon the Securities (other than by reason of a relationship described in
Section 311(b) of the Trust Indenture Act), the Trustee shall be subject to any and all applicable provisions of the Trust Indenture Act regarding the collection of claims against the Company or such other obligor. For purposes of
Section 311(b) of the Trust Indenture Act:

(a) the term "cash transaction" means any transaction in which full payment for goods or securities sold is made within seven days after delivery of the goods or securities in currency or in checks or other orders drawn upon banks or bankers and payable upon demand;

-43-

(b) the term "self-liquidating paper" means any draft, bill of exchange, acceptance or obligation which is made, drawn, negotiated or incurred by the Company or such obligor for the purpose of financing the purchase, processing, manufacturing, shipment, storage or sale of goods, wares or merchandise and which is secured by documents evidencing title to, possession of, or a lien upon, the goods, wares or merchandise or the receivables or proceeds arising from the sale of the goods, wares or merchandise previously constituting the security, provided the security is received by the Trustee simultaneously with the creation of the creditor relationship with the Company or such obligor arising from the making, drawing, negotiating or incurring of the draft, bill of exchange, acceptance or obligation.

SECTION 914. CO-TRUSTEES AND SEPARATE TRUSTEES.

At any time or times, for the purpose of meeting the legal requirements of any applicable jurisdiction, the Company and the Trustee shall have power to appoint, and, upon the written request of the Trustee or of the Holders of at least thirty-three per centum (33%) in principal amount of the Securities then Outstanding, the Company shall for such purpose join with the Trustee in the execution and delivery of all instruments and agreements necessary or proper to appoint, one or more Persons approved by the Trustee either to act as co-trustee, jointly with the Trustee, or to act as separate trustee, in either case with such powers as may be provided in the instrument of appointment, and to vest in such Person or Persons, in the capacity aforesaid, any property, title, right or power deemed necessary or desirable, subject to the other provisions of this Section. If the Company does not join in such appointment within 15 days after the receipt by it of a request so to do, or if an Event of Default shall have occurred and be continuing, the Trustee alone shall have power to make such appointment.

Should any written instrument or instruments from the Company be required by any co-trustee or separate trustee so appointed to more fully confirm to such co-trustee or separate trustee such property, title, right or power, any and all such instruments shall, on request, be executed, acknowledged and delivered by the Company.

Every co-trustee or separate trustee shall, to the extent permitted by law, but to such extent only, be appointed subject to the following conditions:

(a) the Securities shall be authenticated and delivered, and all rights, powers, duties and obligations hereunder in respect of the custody of securities, cash and other personal property held by, or required to be deposited or pledged with, the Trustee hereunder, shall be exercised solely, by the Trustee;

(b) the rights, powers, duties and obligations hereby conferred or imposed upon the Trustee in respect of any property covered by such appointment shall be conferred or imposed upon and exercised or performed either by the Trustee or by the Trustee and such co-trustee or separate trustee jointly, as shall be provided in the instrument appointing such co-trustee or separate trustee, except to the extent that under any law of any jurisdiction in which any particular act is to be performed, the Trustee shall be incompetent or unqualified to perform such act, in which event such rights, powers, duties and obligations shall be exercised and performed by such co-trustee or separate trustee;

(c) the Trustee at any time, by an instrument in writing executed by it, with the concurrence of the Company, may accept the resignation of or remove any co-trustee or separate trustee appointed under this Section, and, if an Event of Default shall have occurred and be continuing, the Trustee shall have power to accept the resignation of, or remove, any such co-trustee or separate trustee without the concurrence of the Company. Upon the written request of the Trustee, the Company shall join with the Trustee in the execution and delivery of all instruments and agreements necessary or proper to effectuate such resignation or removal. A successor to any

-44-

co-trustee or separate trustee so resigned or removed may be appointed in the manner provided in this Section;

(d) no co-trustee or separate trustee hereunder shall be personally liable by reason of any act or omission of the Trustee, or any other such trustee hereunder; and

(e) any Act of Holders delivered to the Trustee shall be deemed to have been delivered to each such co-trustee and separate trustee.

SECTION 915. APPOINTMENT OF AUTHENTICATING AGENT.

The Trustee may appoint an Authenticating Agent or Agents with respect to the Securities of one or more series, or any Tranche thereof, which shall be authorized to act on behalf of the Trustee to authenticate Securities of such series or Tranche issued upon original issuance, exchange, registration of transfer or partial redemption thereof or pursuant to Section 306, and Securities so authenticated shall be entitled to the benefits of this Indenture and shall be valid and obligatory for all purposes as if authenticated by the Trustee hereunder. Wherever reference is made in this Indenture to the authentication and delivery of Securities by the Trustee or the Trustee's certificate of authentication, such reference shall be deemed to include authentication and delivery on behalf of the Trustee by an Authenticating Agent and a certificate of authentication executed on behalf of the Trustee by an Authenticating Agent. Each Authenticating Agent shall be acceptable to the Company and shall at all times be a corporation organized and doing business under the laws of the United States, any State or Territory thereof or the District of Columbia or the Commonwealth of Puerto Rico, authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of not less than $50,000,000 and subject to supervision or examination by Federal or State authority. If such Authenticating Agent publishes reports of condition at least annually, pursuant to law or to the requirements of said supervising or examining authority, then for the purposes of this Section, the combined capital and surplus of such Authenticating Agent shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, such Authenticating Agent shall resign immediately in the manner and with the effect specified in this Section.

Any corporation into which an Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which such Authenticating Agent shall be a party, or any corporation succeeding to the corporate agency or corporate trust business of an Authenticating Agent, shall continue to be an Authenticating Agent, provided such corporation shall be otherwise eligible under this Section, without the execution or filing of any paper or any further act on the part of the Trustee or the Authenticating Agent.

An Authenticating Agent may resign at any time by giving written notice thereof to the Trustee and to the Company. The Trustee may at any time terminate the agency of an Authenticating Agent by giving written notice thereof to such Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time such Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section, the Trustee may appoint a successor Authenticating Agent which shall be acceptable to the Company. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all the rights, powers and duties of its predecessor hereunder, with like effect as if originally named as an Authenticating Agent. No successor Authenticating Agent shall be appointed unless eligible under the provisions of this Section.

The Trustee agrees to pay to each Authenticating Agent from time to time reasonable compensation for its services under this Section, and the Trustee shall be entitled to be reimbursed for such payments, in accordance with, and subject to the provisions of Section 907.

The provisions of Sections 308, 904 and 905 shall be applicable to each Authenticating Agent.

-45-

If an appointment with respect to the Securities of one or more series, or any Tranche thereof, shall be made pursuant to this Section, the Securities of such series or Tranche may have endorsed thereon, in addition to the Trustee's certificate of authentication, an alternate certificate of authentication substantially in the following form:

This is one of the Securities of the series designated therein referred to in the within-mentioned Indenture.

Dated:

Bank One Trust Company, National Association, As Trustee

By:

As Authenticating Agent

By:
Authorized Signatory

If all of the Securities of a series may not be originally issued at one time, and if the Trustee does not have an office capable of authenticating Securities upon original issuance located in a Place of Payment where the Company wishes to have Securities of such series authenticated upon original issuance, the Trustee, if so requested by the Company in writing (which writing need not comply with Section 102 and need not be accompanied by an Opinion of Counsel), shall appoint, in accordance with this Section and in accordance with such procedures as shall be acceptable to the Trustee, an Authenticating Agent having an office in a Place of Payment designated by the Company with respect to such series of Securities.

SECTION 1202. SUPPLEMENTAL INDENTURES WITH CONSENT OF HOLDERS.

With the consent of the Holders of not less than a majority in aggregate principal amount of the Securities of all series then Outstanding under this Indenture, considered as one class, by Act of said Holders delivered to the Company and the Trustee, the Company, when authorized by a Board Resolution, and the Trustee may enter into an indenture or indentures supplemental hereto for the purpose of adding any provisions to, or changing in any manner or eliminating any of the provisions of, this Indenture; provided, however, that if there shall be Securities of more than one series Outstanding hereunder and if a proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such series, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all series so directly affected, considered as one class, shall be required; and provided, further, that if the Securities of any series shall have been issued in more than one Tranche and if the proposed supplemental indenture shall directly affect the rights of the Holders of Securities of one or more, but less than all, of such Tranches, then the consent only of the Holders of a majority in aggregate principal amount of the Outstanding Securities of all Tranches so directly affected, considered as one class, shall be required; and provided, further, that no such supplemental indenture shall:

(a) change the Stated Maturity of the principal of, or any installment of principal of or interest on (except as provided in Section 312 hereof), any Security, or reduce the principal amount thereof or the rate of interest thereon (or the amount of any installment of interest thereon) or change the method of calculating such rate or reduce any premium payable upon the redemption thereof, or reduce the amount of the principal of a Discount Security that would be due and payable upon a declaration of acceleration of the Maturity thereof pursuant to Section 802, or change the coin or currency (or other property), in which any Security or any premium or the interest thereon is payable, or impair the right to institute suit for the enforcement of any such payment on or after the Stated Maturity of any Security (or, in the case of redemption, on or after the Redemption Date), without, in any such case, the consent of the Holder of such Security, or

-49-

(b) reduce the percentage in principal amount of the Outstanding Securities of any series or any Tranche thereof, the consent of the Holders of which is required for any such supplemental indenture, or the consent of the Holders of which is required for any waiver of compliance with any provision of this Indenture or of any default hereunder and its consequences, or reduce the requirements of Section 1304 for quorum or voting, without, in any such case, the consent of the Holders of each Outstanding Security of such series or Tranche, or

(c) modify any of the provisions of this Section, Section 607 or
Section 813 with respect to the Securities of any series, or any Tranche thereof, or except to increase the percentages in principal amount referred to in this Section or such other Sections or to provide that other provisions of this Indenture cannot be modified or waived without the consent of the Holder of each Outstanding Security affected thereby; provided, however, that this clause shall not be deemed to require the consent of any Holder with respect to changes in the references to "the Trustee" and concomitant changes in this Section, or the deletion of this proviso, in accordance with the requirements of clause (b) of Section 911 and clause (h) of Section 1201.

A supplemental indenture which changes or eliminates any covenant or other provision of this Indenture which has expressly been included solely for the benefit of one or more particular series of Securities, or of one or more Tranches thereof, or which modifies the rights of the Holders of Securities of such series or Tranches with respect to such covenant or other provision, shall be deemed not to affect the rights under this Indenture of the Holders of Securities of any other series or Tranche.

It shall not be necessary for any Act of Holders under this Section to approve the particular form of any proposed supplemental indenture, but it shall be sufficient if such Act shall approve the substance thereof. A waiver by a Holder of such Holder's right to consent under this Section shall be deemed to be a consent of such Holder.

SECTION 1203. EXECUTION OF SUPPLEMENTAL INDENTURES.

In executing, or accepting the additional trusts created by, any supplemental indenture permitted by this Article or the modifications thereby of the trusts created by this Indenture, the Trustee shall be entitled to receive, and (subject to Section 901) shall be fully protected in relying upon, an Opinion of Counsel stating that the execution of such supplemental indenture is authorized or permitted by this Indenture.

Any supplemental indenture permitted by this Article may restate this Indenture in its entirety, and, upon the execution and delivery thereof, any such restatement shall supersede this Indenture as theretofore in effect for all purposes.

SECTION 1205. CONFORMITY WITH TRUST INDENTURE ACT.

Every supplemental indenture executed pursuant to this Article shall conform to the requirements of the Trust Indenture Act as then in effect.

-50-

SECTION 1206. REFERENCE IN SECURITIES TO SUPPLEMENTAL INDENTURES.

Securities of any series, or any Tranche thereof, authenticated and delivered after the execution of any supplemental indenture pursuant to this Article may, and shall if required by the Trustee, bear a notation in form approved by the Trustee as to any matter provided for in such supplemental indenture. If the Company shall so determine, new Securities of any series, or any Tranche thereof, so modified as to conform, in the opinion of the Trustee and the Company, to any such supplemental indenture may be prepared and executed by the Company and authenticated and delivered by the Trustee in exchange for Outstanding Securities of such series or Tranche.

SECTION 1207. MODIFICATION WITHOUT SUPPLEMENTAL INDENTURE.

If the terms of any particular series of Securities shall have been established in a Board Resolution or an Officer's Certificate pursuant to a Board Resolution as contemplated by Section 301, and not in an indenture supplemental hereto, additions to, changes in or the elimination of any of such terms may be effected by means of a supplemental Board Resolution or Officer's Certificate, as the case may be, delivered to, and accepted by, the Trustee; provided, however, that such supplemental Board Resolution or Officer's Certificate shall not be accepted by the Trustee or otherwise be effective unless all conditions set forth in this Indenture which would be required to be satisfied if such additions, changes or elimination were contained in a supplemental indenture shall have been appropriately satisfied. Upon the acceptance thereof by the Trustee, any such supplemental Board Resolution or Officer's Certificate shall be deemed to be a "supplemental indenture" for purposes of Section 1204 and 1206.

We have acted as counsel for Interstate Power and Light Company, an Iowa corporation (the "Company"), in connection with the preparation of a Registration Statement on Form S-3 (the "Registration Statement"), including the Prospectus constituting a part thereof (the "Prospectus"), to be filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the "Securities Act"), and relating to the issuance and sale by the Company of up to $100,000,000 aggregate principal amount of senior unsecured debt securities (the "Debentures") in the manner set forth in the Registration Statement. The Debentures will be issued under the Indenture, dated as of August 20, 2003 (the "Indenture"), between the Company and Bank One Trust Company, National Association, as Trustee, and an officers' certificate (the "Officers' Certificate") providing for the issuance of the Debentures.

As counsel to the Company in connection with the proposed issue and sale of the above-referenced securities, we have examined: (a) the Registration Statement, including the Prospectus, and the exhibits (including those incorporated by reference) constituting a part of the Registration Statement;
(b) the Company's Restated Articles of Incorporation and Bylaws, each as amended to date; (c) the Indenture; and (d) such other proceedings, documents and records as we have deemed necessary to enable us to render this opinion.

In our examination of the above-referenced documents, we have assumed the genuineness of all signatures, the authenticity of all documents, certificates and instruments submitted to us as originals and the conformity with the originals of all documents submitted to us as copies.

Based upon the foregoing, we are of the opinion that:

1. The Company is validly existing as a corporation under the laws of the State of Iowa.

2. The Debentures, when executed, authenticated and issued in accordance with the resolutions adopted by the Board of Directors of the Company on August 20, 2003 and in the manner and for the consideration contemplated by the Registration Statement and the Prospectus, will be legally issued and valid and binding obligations of the Company enforceable in accordance with their terms, except as enforcement thereof may be limited by bankruptcy or other applicable laws affecting the enforcement of creditors' rights generally or the application of equitable

principles; provided, that prior to the issuance of the Debentures there shall be taken various proceedings in the manner contemplated by us as counsel, which include the following:

a. The completion of the requisite procedure under the applicable provisions of the Securities Act and the Trust Indenture Act of 1939, as amended;

b. The completion of the requisite procedure relating to the authorization by the Illinois Commerce Commission of the issuance and sale of the Debentures and the compliance by the Company with such authorization as well as compliance with the other regulatory authorizations relating to the issuance and sale of the Debentures;

c. The further authorization by one or more specified senior executive officers of the Company of the Officers' Certificate relating to the Debentures, issuance of the Debentures and related matters; and

d. The execution and delivery of the Officers' Certificate and the taking of other actions provided in the Indenture with respect to the issuance of unsecured debt securities thereunder.

We are qualified to practice law in the State of Wisconsin and we do not purport to be experts on the law other than that of the State of Wisconsin and the federal laws of the United States of America. We express no opinion as to the laws of any jurisdiction other than the State of Wisconsin and the federal laws of the United States. To the extent matters covered by our opinion are governed by the laws of a jurisdiction other than the State of Wisconsin, we have assumed, without independent investigation, that the applicable laws of such jurisdiction are identical in all relevant respects to the substantive laws of the State of Wisconsin.

We hereby consent to the reference to our firm under the caption "Legal Matters" in the Prospectus which is filed as part of the Registration Statement, and to the filing of this opinion as an exhibit to the Registration Statement. In giving this consent, we do not admit that we are "experts" within the meaning of Section 11 of the Securities Act or within the category of persons whose consent is required by Section 7 of the Securities Act.

Very truly yours,

/s/ Foley & Lardner

EXHIBIT 1

A COPY OF THE ARTICLES OF ASSOCIATION OF THE
TRUSTEE NOW IN EFFECT

AMENDED AND RESTATED
ARTICLES OF ASSOCIATION
of

BANK ONE TRUST COMPANY, National Association

FIRST. The title of this Association shall be BANK ONE TRUST COMPANY, National Association.

SECOND. The main office of the Association shall be in the City of Columbus, County of Franklin, State of Ohio.

The business of the Association will be limited to the fiduciary powers and the support of activities incidental to the exercise of those powers. The Association will not expand or alter its business beyond that stated in this article without the prior approval of the Comptroller of the Currency.

THIRD. The Board of Directors of this Association shall consist of not less than five nor more than twenty-five persons, the exact number to be fixed and determined from time to time by resolution of a majority of the full Board of Directors or by resolution of a majority of the shareholders at any annual or special meeting thereof. Each director shall own common or preferred stock of the Association, or of a holding company owning the Association, with an aggregate par, fair market or equity value of not less than $1,000, as of either
(i) the date of purchase, (ii) the date the person became a director, or (iii) the date of that person's most recent election to the Board of Directors, whichever is more recent. Any combination of common or preferred stock of the Association or holding company may be used.

Any vacancy in the Board of Directors may be filled by action of a majority of the remaining directors between meetings of shareholders. The Board of Directors may not increase the number of directors between meetings of shareholders to a number which: (1) exceeds by more than two the number of directors last elected by shareholders where the number was 15 or less; or (2) exceeds by more than four the number of directors last elected by shareholders where the number was 16 or more, but in no event shall the number of directors exceed 25.

Terms of directors, including directors selected to fill vacancies, shall expire at the next regular meeting of shareholders at which directors are elected, unless the directors resign or are removed from office.

Despite the expiration of a director's term, the director shall continue to serve until his or her successor is elected and qualifies or until there is a decrease in the number of directors and his or her position is eliminated.

-4-

Honorary or advisory members of the Board of Directors, without voting power or power of final decision in matters concerning the business of the Association, may be appointed by resolution of a majority of the full Board of Directors, or by resolution of shareholders at any annual or special meeting. Honorary or advisory directors shall not be counted to determine the number of directors of the Association or the presence of a quorum in connection with any board action, and shall not be required to own qualifying shares.

FOURTH. There shall be an annual meeting of the shareholders to elect directors and transact whatever other business may be brought before the meeting. It shall be held at the main office or any other convenient place the Board of Directors may designate, on the day of each year specified therefor in the Bylaws or, if that day falls on a legal holiday in the state in which the Association is located, on the next following banking day. If no election is held on the day fixed or in the event of a legal holiday on the following banking day, an election may be held on any subsequent day within 60 days of the day fixed, to be designated by the Board of Directors or, if the directors fail to fix the day, by shareholders representing two-thirds of the shares issued and outstanding. In all cases at least 10 days advance notice of the meeting shall be given to the shareholders by first class mail.

In all elections of directors, the number of votes each common shareholder may cast will be determined by multiplying the number of shares such shareholder owns by the number of directors to be elected. Those votes may be cumulated and cast for a single candidate or may be distributed among two or more candidates in the manner selected by the shareholder. On all other questions, each common shareholder shall be entitled to one vote for each share of stock held by such shareholder. If the issuance of preferred stock with voting rights has been authorized by a vote of shareholders owning a majority of the common stock of the association, preferred shareholders will have cumulative voting rights and will be included within the same class as common shareholders, for purposes of elections of directors.

A director may resign at any time by delivering written notice to the Board of Directors, its chairperson, or to the Association, which resignation shall be effective when the notice is delivered unless the notice specifies a later effective date.

A director may be removed by shareholders at a meeting called to remove him or her, when notice of the meeting stating that the purpose or one of the purposes is to remove him or her is provided, if there is a failure to fulfill one of the affirmative requirements for qualification, or for cause, provided, however, that a director may not be removed if the number of votes sufficient to elect him or her under cumulative voting is voted against his or her removal.

FIFTH. The authorized amount of capital stock of this Association shall be eighty thousand shares of common stock of the par value of ten dollars ($10.00) each; but said capital stock may be increased or decreased from time to time, according to the provisions of the laws of the United States.

No holder of shares of the capital stock of any class of the Association shall have any preemptive or preferential right of subscription to any shares of any class of stock of the Association, whether now or hereafter authorized, or to any obligations convertible into

stock of the Association, issued or sold, nor any right of subscription to any thereof other than such, if any, as the Board of Directors, in its discretion, may from time to time determine and at such price as the Board of Directors may from time to time fix. Unless otherwise specified in the Articles of Association or required by law, (1) all matters requiring shareholder action, including amendments to the Articles of Association, must be approved by shareholders owning a majority voting interest in the outstanding voting stock, and (2) each shareholder shall be entitled to one vote per share.

Unless otherwise specified in the Articles of Association or required by law, all shares of voting stock shall be voted together as a class on any matters requiring shareholder approval. If a proposed amendment would affect two or more classes or series in the same or a substantially similar way, all the classes or series so affected must vote together as a single voting group on the proposed amendment.

Shares of the same class or series may be issued as a dividend on a pro rata basis and without consideration. Shares of another class or series may be issued as share dividends in respect of a class or series of stock if approved by a majority of the votes entitled to be cast by the class or series to be issued unless there are no outstanding shares of the class or series to be issued. Unless otherwise provided by the Board of Directors, the record date for determining shareholders entitled to a share dividend shall be the date the Board of Directors authorizes the share dividend.

Unless otherwise provided in the Bylaws, the record date for determining shareholders entitled to notice of and to vote at any meeting is the close of business on the day before the first notice is mailed or otherwise sent to the shareholders, provided that in no event may a record date be more than 70 days before the meeting.

If a shareholder is entitled to fractional shares pursuant to preemptive rights, a stock dividend, consolidation or merger, reverse stock split or otherwise, the Association may: (a) issue fractional shares or; (b) in lieu of the issuance of fractional shares, issue script or warrants entitling the holder to receive a full share upon surrendering enough script or warrants to equal a full share;
(c) if there is an established and active market in the Association's stock, make reasonable arrangements to provide the shareholder with an opportunity to realize a fair price through sale of the fraction, or purchase of the additional fraction required for a full share; (d) remit the cash equivalent of the fraction to the shareholder; or (e) sell full shares representing all the fractions at public auction or to the highest bidder after having solicited and received sealed bids from at least three licensed stock brokers, and distribute the proceeds pro rata to shareholders who otherwise would be entitled to the fractional shares. The holder of a fractional share is entitled to exercise the rights for shareholder, including the right to vote, to receive dividends, and to participate in the assets of the Association upon liquidation, in proportion to the fractional interest. The holder of script or warrants is not entitled to any of these rights unless the script or warrants explicitly provide for such rights. The script or warrants may be subject to such additional conditions as:
(1) that the script or warrants will become void if not exchanged for full shares before a specified date; and (2) that the shares for which the script or warrants are exchangeable may be sold at the option of the Association and the proceeds paid to scriptholders.

-6-

The Association, at any time and from time to time, may authorize and issue debt obligations, whether or not subordinated, without the approval of the shareholders. Obligations classified as debt, whether or not subordinated, which may be issued by the Association without the approval of shareholders, do not carry voting rights on any issue, including an increase or decrease in the aggregate number of the securities, or the exchange or reclassification of all or part of securities into securities of another class or series.

SIXTH. The Board of Directors shall appoint one of its members president of this Association, and one of its members chairperson of the board and shall have the power to appoint one or more vice presidents, a secretary who shall keep minutes of the directors' and shareholders' meetings and be responsible for authenticating the records of the Association, and such other officers and employees as may be required to transact the business of this Association.

(1) Define the duties of the officers, employees, and agents of the Association.

(2) Delegate the performance of its duties, but not the responsibility for its duties, to the officers, employees, and agents of the Association.

(3) Fix the compensation and enter into employment contracts with its officers and employees upon reasonable terms and conditions consistent with applicable law.

(4) Dismiss officers and employees.

(5) Require bonds from officers and employees and to fix the penalty thereof.

(6) Ratify written policies authorized by the Association's management or committees of the board.

(7) Regulate the manner in which any increase or decrease of the capital of the Association shall be made, provided that nothing herein shall restrict the power of shareholders to increase or decrease the capital of the association in accordance with law, and nothing shall raise or lower from two-thirds the percentage for shareholder approval to increase or reduce the capital.

(8) Manage and administer the business and affairs of the Association.

(9) Adopt initial Bylaws, not inconsistent with law or the Articles of Association, for managing the business and regulating the affairs of the Association.

(10) Amend or repeal Bylaws, except to the extent that the Articles of Association reserve this power in whole or in part to shareholders.

(11) Make contracts.

(12) Generally perform all acts that are legal for a Board of Directors to perform.

SEVENTH. The Board of Directors shall have the power to change the location of the main office of this Association to any other place within the limits of the City of Columbus, State of Ohio, without the approval of the shareholders; and shall have the power to change the location of the main office of this Association to any other place outside the limits of the City of Columbus, State of Ohio, but not more than thirty miles beyond such limits, with the affirmative vote of shareholders owning two-thirds of the stock of the Association, subject to receipt of a certificate of approval from the Comptroller of the Currency. The Board of Directors shall have the power to establish or change the location of any branch or branches of the Association to any other location permitted under applicable law without the approval of the shareholders, subject to approval by the Office of the Comptroller of the Currency. The Board of Directors shall have the power to establish or change the location of any nonbranch office or facility of the Association without the approval of the shareholders.

EIGHTH. The corporate existence of this Association shall continue until termination according to the laws of the United States.

NINTH. The Board of Directors of this Association, or any shareholders owning, in the aggregate, not less than 20 percent of the stock of this Association, may call a special meeting of shareholders at any time. Unless otherwise provided by the Bylaws or the laws of the United States, or waived by shareholders, a notice of the time, place, and purpose of every annual and special meeting of the shareholders shall be given by first-class mail, postage prepaid, mailed at least 10, and no more than 60, days prior to the date of the meeting to each shareholder of record at his/her address as shown upon the books of this Association. Unless otherwise provided by the Bylaws, any action requiring approval of shareholders must be effected at a duly called annual or special meeting.

TENTH. The Association shall provide indemnification as set forth below:

Every person who is or was a Director, officer or employee of the Association or of any other corporation which he served as a Director, officer or employee at the request of the Association as part of his regularly assigned duties may be indemnified by the Association in accordance with the provisions of this Article against all liability (including, without limitation, judgments, fines, penalties, and settlements) and all reasonable expenses (including, without limitation, attorneys' fees and investigative expenses) that may be incurred or paid by him in connection with any claim, action, suit or proceeding, whether civil, criminal or administrative (all referred to hereafter in this Article as "Claims") or in connection with any appeal relating thereto in which he may become involved as a party or otherwise or with which he may be threatened by reason of his being or having been a Director, officer or employee of the Association or such other corporation, or by reason of any action taken or omitted by him in his capacity as such Director, officer or employee, whether or not he continues to be such at the time such liability or expenses are incurred; provided that nothing contained in this Article shall be construed to permit indemnification of any such person who is adjudged guilty of, or liable for, willful misconduct, gross neglect of duty or criminal acts, unless, at the time such indemnification is sought, such indemnification in such instance is permissible under applicable law and regulations, including published rulings of the Comptroller of the Currency or other appropriate

-8-

supervisory or regulatory authority; and provided further that there shall be no indemnification of Directors, officers, or employees against expenses, penalties, or other payments incurred in an administrative proceeding or action instituted by an appropriate regulatory agency which proceeding or action results in a final order assessing civil money penalties or requiring affirmative action by an individual or individuals in the form of payments to the Association.

Every person who may be indemnified under the provisions of this Article and who has been wholly successful on the merits with respect to any Claim shall be entitled to indemnification as of right. Except as provided in the preceding sentence, any indemnification under this Article shall be at the sole discretion of the Board of Directors and shall be made only if the Board of Directors or the Executive Committee acting by a quorum consisting of Directors who are not parties to such Claim shall find or if independent legal counsel (who may be the regular counsel of the Association) selected by the Board of Directors or Executive Committee whether or not a disinterested quorum exists shall render their opinion that in view of all of the circumstances then surrounding the Claim, such indemnification is equitable and in the best interests of the Association. Among the circumstances to be taken into consideration in arriving at such a finding or opinion is the existence or non-existence of a contract of insurance or indemnity under which the Association would be wholly or partially reimbursed for such indemnification, but the existence or non-existence of such insurance is not the sole circumstance to be considered nor shall it be wholly determinative of whether such indemnification shall be made. In addition to such finding or opinion, no indemnification under this Article shall be made unless the Board of Directors or the Executive Committee acting by a quorum consisting of Directors who are not parties to such Claim shall find or if independent legal counsel (who may be the regular counsel of the Association) selected by the Board of Directors or Executive Committee whether or not a disinterested quorum exists shall render their opinion that the Directors, officer or employee acted in good faith in what he reasonably believed to be the best interests of the Association or such other corporation and further in the case of any criminal action or proceeding, that the Director, officer or employee reasonably believed his conduct to be lawful. Determination of any Claim by judgment adverse to a Director, officer or employee by settlement with or without Court approval or conviction upon a plea of guilty or of nolo contendere or its equivalent shall not create a presumption that a Director, officer or employee failed to meet the standards of conduct set forth in this Article. Expenses incurred with respect to any Claim may be advanced by the Association prior to the final disposition thereof upon receipt of an undertaking satisfactory to the Association by or on behalf of the recipient to repay such amount unless it is ultimately determined that he is entitled to indemnification under this Article.

The rights of indemnification provided in this Article shall be in addition to any rights to which any Director, officer or employee may otherwise be entitled by contract or as a matter of law. Every person who shall act as a Director, officer or employee of this Association shall be conclusively presumed to be doing so in reliance upon the right of indemnification provided for in this Article.

-9-

ELEVENTH. These Articles of Association may be amended at any regular or special meeting of the shareholders by the affirmative vote of the holders of a majority of the stock of this Association, unless the vote of the holders of a greater amount of stock is required by law, and in that case by the vote of the holders of such greater amount. The Association's Board of Directors may propose one or more amendments to the Articles of Association for submission to the shareholders.

SECTION 7. Quorum; Majority Vote. A quorum of directors shall be required to transact business at any regular or special meeting of the Board of Directors. A majority of the directors shall constitute a quorum. Each director shall be entitled to one vote. A vote by a majority of the directors present at any regular or special meeting

SECTION 11. Participation in Meetings by Telephone Unless otherwise restricted by law or the Articles of Association, members of the Board of Directors, or of any committee thereof, may participate in a meeting of the Board of Directors or committee by means of conference telephone or similar communications equipment which allows each person participating in the meeting to hear each other. Participation in such a meeting shall constitute presence in person at such meeting.

SECTION 12. Consent of Directors in Lieu of Meeting. Unless otherwise restricted by law or the Articles of Association, any action required or permitted to be taken at any meeting of the Board of Directors, or of any committee thereof, may be taken without a meeting if all members of the Board or committee, as the case may be, consent thereto in writing, and the writing or writings are filed with the minutes of proceedings of the Board or committee.

SECTION 13. Committees. The Board of Directors may, by resolution passed by a majority of the entire Board, designate one or more committees, each committee to consist of two or more of the Directors of the Bank. The Board of Directors may designate one or more Directors as alternate members of any committee, who may replace any absent or disqualified member at any meeting of the committee. Any such committee, to the extent provided in the resolution, shall have and may exercise the powers of the Board of Directors in the management of the business and affairs of the Bank, and may authorize the seal of the Bank to be affixed to all papers which may require it; provided, however, that in the absence or disqualification of any member of such committee or committees, the member or members thereof present at any meeting and not disqualified from voting, whether or not he or they constitute a quorum, may unanimously appoint another member of the Board of Directors to act at the meeting in the place of any such absent or disqualified member. Such committee or committees shall have such name or names as may be determined from time to time by resolution adopted by the Board of Directors. As used in

-16-

these By-Laws, "entire Board" means the total number of Directors the Bank would have if there were no vacancies.

During intervals between the regular meetings of the Board of Directors, the Executive Committee, to the extent permitted by law, the Articles of Association of the Bank and the By-Laws, shall have and may exercise the powers of the Board of Directors in the management of the business and affairs of the Bank.

Unless otherwise provided by the Board of Directors, a majority of the members of any committee appointed by the Board of Directors pursuant to this
Section shall constitute a quorum at any meeting thereof and the act of a majority of the members present at a meeting at which a quorum is present shall be the act of such committee. Any such committee shall, subject to any rules prescribed by the Board of Directors, prescribe its own rules for calling, giving notice of and holding meetings and its method of procedure at such meetings and shall keep a written record of all action taken by it. Each committee shall keep regular minutes of its meetings and report the same to the Board of Directors when required.
