ABOUT THIS PROSPECTUS SUPPLEMENT

This document is in two parts. The first part is this prospectus supplement, which describes the specific terms of the Senior Notes that we are offering and other matters relating to us and our financial condition. The second part is the attached base prospectus, which gives more general information about securities we may offer from time to time, some of which does not apply to the Senior Notes we are offering. The description of the terms of the Senior Notes in this prospectus supplement supplements the description in the accompanying prospectus under “Description of Debt Securities,” and to the extent it is inconsistent with that description, the information in this prospectus supplement replaces the information in the accompanying prospectus. Generally, when we refer to the prospectus, we are referring to both parts of this document combined. If information in the prospectus supplement differs from information in the accompanying prospectus, you should rely on the information in this prospectus supplement.

RISK FACTORS

An investment in the Senior Notes involves certain risks. You should carefully consider the risks described below, and all of the other information included or incorporated by reference in this prospectus supplement and the accompanying prospectus, before making an investment decision. Our business, financial condition or results of operations could be materially adversely affected by any of these risks. The market or trading price of the Senior Notes could decline due to any of these risks, and you may lose all or part of your investment. Please note that additional risks not presently known to us or that we currently deem immaterial may also impair our business and operations.

Risks Relating to Our Business

Certain risks relating to us and our business are described under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2009, which is incorporated by reference into this prospectus supplement. You should carefully review and consider this information.

Risks Relating to the Senior Notes

The Senior Notes are Effectively Subordinated to Any Secured Debt and Any Liabilities of our Subsidiaries.

The Senior Notes are our general unsecured and unsubordinated obligations. Accordingly, the Senior Notes will rank senior in right of payment to any future indebtedness that is expressly subordinated in right of payment to the Senior Notes, equal in right of payment to our existing and future indebtedness that is not subordinated, junior in right of payment to any future secured indebtedness to the extent of the value of the assets securing such indebtedness, and structurally junior to all existing and future indebtedness and other liabilities of our subsidiaries. In the event of our bankruptcy, liquidation, reorganization or other winding up, our assets that secure debt ranking senior or equal in right of payment to the Senior Notes will be available to pay obligations on the Senior Notes only after any secured debt has been repaid in full from these assets. There may not be sufficient assets remaining to pay any or all amounts due on Senior Notes then outstanding.

As of June 30, 2010, on an unconsolidated basis we had $835.7 million of outstanding indebtedness and our subsidiaries collectively had outstanding indebtedness of $130.6 million, in each case, excluding inter-Company indebtedness. After giving effect to the issuance of the Senior Notes, our total indebtedness would have been $1,216.3 million as of June 30, 2010, on a consolidated basis.

The Senior Notes are Our Obligations Only, and a Portion of Our Operations are Conducted through, and a Portion of Our Consolidated Assets are Held by, Our Subsidiaries.

The Senior Notes are our obligations exclusively and are not guaranteed by any of our subsidiaries. A portion of our consolidated assets are held by our subsidiaries. Accordingly, our ability to service our debt, including the Senior Notes, depends partially on the results of operations of our subsidiaries and upon the ability of such subsidiaries to provide us with cash, whether in the form of dividends, loans or otherwise, to pay amounts due on our obligations, including the Senior Notes. Our subsidiaries are separate and distinct legal entities and have no obligation, contingent or otherwise, to make payments on the Senior Notes or to make any funds available for that purpose. In addition, dividends, loans or other distributions to us from such subsidiaries may be subject to contractual and other restrictions and are subject to other business considerations.

Our Failure to Remain in Compliance with the Covenants in Our Multi-Currency Revolving Credit Facility or Term Loan May Result in an Event of Default.

Our multi-currency revolving credit facility contains covenants that we believe are customary for credit facilities of this nature, including requiring us to meet specified financial ratios and financial tests. Our ability to borrow under our revolving credit facility will depend upon satisfaction of these covenants. Events beyond our control can affect our ability to meet those covenants. Our multi-currency revolving credit facility contains covenants restricting our ability to, among other things: (i) create, incur or assume additional debt (including hedging arrangements), (ii) incur liens or engage in saleleaseback transactions, (iii) make loans and investments, (iv) guarantee obligations, (v) engage in certain mergers, acquisitions and asset sales, and (vi) change the nature of our business and the business conducted by our subsidiaries. We are also required to comply with financial covenants with respect to a maximum leverage ratio and a minimum consolidated interest coverage ratio.

S-6

If we are unable to meet the terms of our financial or other covenants, or if we breach any of these covenants, a default could occur under the revolving credit facility. A default, if not waived by our lenders, could result in the acceleration of our outstanding indebtedness, including the Senior Notes, and cause our debt to become immediately due and payable. If acceleration occurs, we may not be able to repay our debt and may not be able to borrow sufficient funds to refinance our debt. Even if new financing is offered to us, it may not be on terms acceptable to us.

The Senior Notes do not Restrict Our Ability to Incur Additional Debt or Prohibit us from Taking Other Action that could Negatively Impact Holders of the Senior Notes.

We are not restricted under the terms of the indenture or the Senior Notes from incurring additional indebtedness. The terms of the indenture limit our ability to incur indebtedness secured by principal properties or the stock or indebtedness of subsidiaries that own principal properties, to enter into sale and leaseback transactions and to enter into certain mergers or consolidations and to transfer substantially all of our assets. However, these limitations are subject to numerous exceptions. In addition, the Senior Notes do not require us to achieve or maintain any minimum financial results relating to our financial position or results of operations. Our ability to recapitalize, incur additional debt, secure existing or future debt with assets other than principal properties, or take a number of other actions that are not limited by the terms of the indenture and the Senior Notes, including repurchasing subordinated indebtedness or common stock or to pay dividends or make other distributions to our stockholders, could have the effect of diminishing our ability to make payments on the Senior Notes when due, causing a loss in the trading value of your Senior Notes, if any, and increasing the risk that the credit rating of the Senior Notes is lowered or withdrawn.

We May not have Sufficient Cash to Repurchase the Senior Notes Upon the Occurrence of a “Change of Control Repurchase Event.”

We will be required to offer to repurchase all of the Senior Notes upon the occurrence of a “change of control repurchase event” (as defined below). We may not, however, have sufficient cash at that time or have the ability to arrange necessary financing on acceptable terms to repurchase the Senior Notes under such circumstances. If we are unable to repurchase the Senior Notes upon the occurrence of a change of control repurchase event, it would result in an event of default under the indenture governing the Senior Notes. A default under the indenture could also lead to a default under the agreements governing our existing or future indebtedness. If the repayment of the related indebtedness were to be accelerated after any applicable notice or grace periods, we may not have sufficient funds to repay the indebtedness and repurchase the Senior Notes.

Our Financial Performance and Other Factors could Adversely Impact Our Ability to Make Payments on the Senior Notes.

Our ability to make scheduled payments with respect to our indebtedness, including the Senior Notes, will depend on our financial and operating performance, which, in turn, is subject to prevailing economic conditions and to financial, business and other factors beyond our control. Our historical financial results have been, and we anticipate that our future financial results will be, subject to fluctuations. We cannot assure you that our business will generate sufficient cash flow from our operations or that future borrowings will be available to us in an amount sufficient to enable us to pay our indebtedness, including the Senior Notes.

We Cannot Assure You that an Active Trading Market will Develop for the Senior Notes.

Prior to this offering, there has been no trading market for the Senior Notes. We do not intend to apply for listing of the Senior Notes on any securities exchange or to arrange for quotation on any interdealer quotation system. We have been informed by the underwriters that they intend to make a market in the Senior Notes after the offering is completed. However, the underwriters may cease their market-making at any time without notice. In addition, the liquidity of the trading market in the Senior Notes, and the market price quoted for the Senior Notes, may be adversely affected by changes in the overall market for this type of security and by changes in our financial performance or prospects or in the prospects for companies in our industry, generally. As a result, we cannot assure you that an active trading market will develop for the Senior Notes. If an active trading market does not develop or is not maintained, the market price and liquidity of the Senior Notes may be adversely affected. In that case you may not be able to sell your Senior Notes at a particular time or you may not be able to sell your Senior Notes at a favorable price or at all.

S-7

Ratings of the Senior Notes May not Reflect all Risks of an Investment in the Senior Notes.

The Senior Notes will be rated by at least one nationally recognized statistical rating organization. The ratings of our Senior Notes will primarily reflect our financial strength and will change in accordance with the rating of our financial strength. Any rating is not a recommendation to purchase, sell or hold any particular security, including the Senior Notes. These ratings do not comment as to market price or suitability for a particular investor. In addition, ratings at any time may be lowered or withdrawn in their entirety. The ratings of the Senior Notes may not reflect the potential impact of all risks related to structure and other factors on any trading market for, or trading value of, your Senior Notes.

We May Choose to Redeem the Senior Notes When Prevailing Interest Rates are Relatively Low.

The Senior Notes are redeemable at our option and we may choose to redeem some or all of the Senior Notes from time to time, especially when prevailing interest rates are lower than the rate on the Senior Notes. If prevailing rates are lower at the time of redemption, you would not be able to reinvest the redemption proceeds in a comparable security at an effective interest rate as high as the interest rate on the Senior Notes being redeemed. Our redemption right also may adversely affect your ability to sell your Senior Notes as the optional redemption date or period approaches.

Our Management will have Broad Discretion in Allocating the net Proceeds of this Offering.

Our management has significant flexibility in applying the net proceeds we expect to receive in this offering. We intend to use the net proceeds from this offering for general corporate purposes, including to repay short-term indebtedness that we have incurred to fund working capital requirements. Because the net proceeds are not required to be allocated to any specific investment or transaction, you cannot determine at this time the value or propriety of our application of the proceeds, and you may not agree with our decisions. In addition, our use of the proceeds from this offering may not yield a significant return or any return at all. The failure by our management to apply these funds effectively could have a negative impact on our business, results of operations or financial condition. See “Use of Proceeds.”

An Increase in Market Interest Rates could Result in a Decrease in the Value of the Senior Notes.

In general, as market interest rates rise, Senior Notes bearing interest at a fixed rate generally decline in value because the premium, if any, over market interest rates will decline. Consequently, if you purchase Senior Notes and market interest rates increase, the market value of your Senior Notes may decline. We cannot predict the future level of market interest rates.

If You are Able to Resell Your Senior Notes, Many Other Factors May Affect the Price You Receive, Which May be Lower than You Believe to be Appropriate.

If you are able to resell your Senior Notes, the price you receive will depend on many other factors that may vary over time, including:


	•	our financial performance;

	•	analysts’ expectations of our future financial performance or the prospects for our industry in general;

	•	the amount of indebtedness we have outstanding;

	•	the market for similar securities;

	•	market interest rates;

	•	the liquidity of the market in which the Senior Notes trade;

	•	the redemption and repayment features of the Senior Notes to be sold; and

	•	the time remaining to maturity of your Senior Notes.

As a result of these factors, you may only be able to sell your Senior Notes at prices below those you believe to be appropriate, including prices below the price you paid for them.

S-8

USE OF PROCEEDS

We estimate the net proceeds to us from the sale of the Senior Notes will be approximately $ , after deducting underwriting discounts and offering expenses payable by us. We intend to use all of the proceeds from the sale of the Senior Notes for general corporate purposes.

DESCRIPTION OF THE SENIOR NOTES

Set forth below is a description of the specific terms of our % Senior Notes due (the “Senior Notes”). This description supplements, and should be read together with, the description of the general terms and provisions of the Senior Notes, some of which may not apply to this offering, set forth in the accompanying prospectus under the caption “Description of Debt Securities.” The following description does not purport to be complete and is subject to, and is qualified in its entirety by reference to, the description in the accompanying prospectus and the Senior Note Indenture (the “Indenture”) dated as of September 23, 1999, as supplemented, between BorgWarner and The Bank of New York Mellon Trust Company, N.A. (formerly known as The Chase Manhattan Trust Company, National Association), as trustee. The Indenture has been qualified as an indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”). The terms of the Indenture are those provided therein and those made a part of the Indenture by the Trust Indenture Act. The Senior Notes will constitute debt securities under the Indenture as described in the accompanying prospectus. In addition to the Senior Notes, we may issue, from time to time, other series of debt securities under the Indenture. Such other series will be separate from and independent of the Senior Notes.

General

The Senior Notes offered hereby will initially be limited to $250,000,000 aggregate principal amount. We may, without the consent of the existing holders of the Senior Notes, issue additional notes having the same terms (other than the issue date and initial interest payment date) so that the existing Senior Notes and the new notes form a single series under the Indenture.

The Senior Notes are to be issued under the Indenture, which is more fully described in the accompanying prospectus.

The Senior Notes will bear interest at the rate set forth on the cover of this prospectus supplement from , 2010, payable on and of each year, beginning on , 2011, to the persons in whose names the Senior Notes are registered at the close of business on the and , as the case may be, immediately preceding such and . Interest on the Senior Notes will be computed on the basis of a 360-day year of twelve 30-day months. The Senior Notes will mature on and are not subject to any sinking fund.

If any interest payment date falls on a day that is not a business day, the interest payment shall be postponed to the next succeeding business day, and no interest on such payment shall accrue for the period from and after such interest payment date. If the scheduled maturity date or the redemption date of the Senior Notes falls on a day that is not a business day, the payment of interest and principal (and premium, if any) will be made on the next succeeding business day, and no interest on such payment shall accrue for the period from and after the scheduled maturity date or redemption date, as the case may be.

Interest payments for the Senior Notes will include accrued interest from and including , 2010 or from and including the last date in respect of which interest has been paid or duly provided for, as the case may be, to but excluding the relevant interest payment date, maturity date, or the redemption date, as the case may be.

The Senior Notes will be issued in the form of one or more global securities registered in the name of the nominee of The Depository Trust Company (which we may refer to along with its successors in such capacity as the depositary). The Senior Notes will only be issued in denominations of $2,000 and integral multiples of $1,000 in excess thereof. Payments on the Senior Notes issued as a global security will generally be made to the depositary or the nominee of the depositary. See “— Book-Entry Issuance” in this prospectus supplement.

Ranking

The Senior Notes will be our general unsecured and unsubordinated obligations and will rank equally in priority with all of our other unsecured and unsubordinated obligations. The Indenture contains no restrictions on the amount of additional indebtedness that we may incur.

S-11

Redemption at Our Option

We may, at our option, redeem the Senior Notes in whole or in part at any time at a redemption price equal to the greater of:


	•	100% of the principal amount of the Senior Notes to be redeemed, plus accrued and unpaid interest to the redemption date for the Senior Notes, and

	•	as determined by the Independent Investment Banker, the sum of the present values of the principal amount of and remaining scheduled payments of interest on the Senior Notes to be redeemed (not including any portion of payments of interest accrued as of the redemption date) discounted to the redemption date on a semi-annual basis at the Treasury Rate plus basis points, plus accrued and unpaid interest to the redemption date for the Senior Notes.

The redemption price will be calculated assuming a 360-day year consisting of twelve 30-day months.

“Comparable Treasury Issue” means the United States Treasury security selected by the Independent Investment Banker as having a maturity comparable to the remaining term of the Senior Notes that would be used, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of comparable maturity to the remaining term of the Senior Notes.

“Comparable Treasury Price” means, with respect to any redemption date:


	•	the average of the Reference Treasury Dealer Quotations for that redemption date, after excluding the highest and lowest of the Reference Treasury Dealer Quotations, or

	•	if the Independent Investment Banker obtains fewer than three Reference Treasury Dealer Quotations, the average of all Reference Treasury Dealer Quotations so received.

“Independent Investment Banker” means one of the Reference Treasury Dealers appointed by us.

“Reference Treasury Dealer” means (a) Morgan Stanley & Co. Incorporated, and its respective successors, unless any of them ceases to be a primary U.S. Government securities dealer in New York City (a “Primary Treasury Dealer”), in which case we shall substitute another Primary Treasury Dealer, and (b) any other Primary Treasury Dealer selected by us.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to us and the trustee by that Reference Treasury Dealer at 5:00 p.m., New York City time, on the third business day preceding that redemption date.

“Treasury Rate” means, with respect to any redemption date, the rate per year equal to the semiannual equivalent yield to maturity of the Comparable Treasury Issue, calculated on the third business day preceding the redemption date, assuming a price for the Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the Comparable Treasury Price for that redemption date.

We will mail notice of any redemption at least 30 days but not more than 60 days before the redemption date to each holder of the Senior Notes to be redeemed.

Unless we default in payment of the redemption price, on and after the redemption date, interest will cease to accrue on the Senior Notes or portions of the Senior Notes called for redemption.

Change of Control Repurchase Event

If a change of control repurchase event occurs, unless we have exercised our right to redeem the Senior Notes as described above, we will make an offer to each holder of Senior Notes to repurchase all or any part (equal to $2,000 and any integral multiples of $1,000 in excess thereof) of that holder’s Senior Notes at a purchase price in cash equal to 101% of the aggregate principal amount of Senior Notes repurchased plus any accrued and unpaid interest on the Senior Notes repurchased to the date of purchase. Within 30 days following any change of control

S-12

repurchase event or, at our option, prior to any change of control, but after the public announcement of the change of control, we will mail a notice to each holder, with a copy to the trustee, describing the transaction or transactions that constitute or may constitute the change of control repurchase event and offering to repurchase Senior Notes on the payment date specified in the notice, which date will be no earlier than 30 days and no later than 60 days from the date such notice is mailed. The notice shall, if mailed prior to the date of consummation of the change of control, state that the offer to purchase is conditioned on the change of control repurchase event occurring on or prior to the payment date specified in the notice. We will comply with the requirements of Rule 14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the repurchase of the Senior Notes as a result of a change of control repurchase event. To the extent that the provisions of any securities laws or regulations conflict with the change of control repurchase event provisions of the Senior Notes, we will comply with the applicable securities laws and regulations and will not be deemed to have breached our obligations under the change of control repurchase event provisions of the Senior Notes by virtue of such conflict.

On the change of control repurchase event payment date, we will, to the extent lawful:


	•	accept for payment all Senior Notes or portions of Senior Notes properly tendered pursuant to our offer;

	•	deposit with the paying agent an amount equal to the aggregate purchase price in respect of all Senior Notes or portions of Senior Notes properly tendered; and

	•	deliver or cause to be delivered to the trustee the Senior Notes properly accepted, together with an officers’ certificate stating the aggregate principal amount of Senior Notes being purchased by us.

The paying agent will promptly mail to each holder of Senior Notes properly tendered the purchase price for the Senior Notes, and the trustee will promptly authenticate and mail (or cause to be transferred by book-entry) to each holder a new note equal in principal amount to any unpurchased portion of any Senior Notes surrendered; provided that each new note will be in a principal amount equal to $2,000 or an integral multiple of $1,000 in excess thereof.

We will not be required to make an offer to repurchase the Senior Notes upon a change of control repurchase event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by us and such third party purchases all Senior Notes properly tendered and not withdrawn under its offer.

The term “below investment grade rating event” means the Senior Notes are rated below investment grade by both rating agencies on any date from the date of the public notice of an arrangement that could result in a change of control until the end of the 60-day period following public notice of the occurrence of a change of control (which period shall be extended so long as the rating of the Senior Notes is under publicly announced consideration for possible downgrade by either of the rating agencies); provided that a below investment grade rating event otherwise arising by virtue of a particular reduction in rating shall not be deemed to have occurred in respect to a particular change of control (and thus shall not be deemed a below investment grade rating event for purposes of the definition of change of control repurchase event hereunder) if the rating agencies making the reduction in rating to which this definition would otherwise apply do not announce or publicly confirm or inform the trustee in writing at its request that the reduction was the result, in whole or in part, of any event or circumstance comprised of or arising as a result of, or in respect of, the applicable change of control (whether or not the applicable change of control shall have occurred at the time of the below investment grade rating event).

The term “change of control” means the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any “person” (as that term is used in Section 13(d)(3) of the Exchange Act) becomes the beneficial owner, directly or indirectly, of more than 50% of our voting stock measured by voting power rather than number of shares.

The term “change of control repurchase event” means the occurrence of both a change of control and a below investment grade rating event.

The term “investment grade” means a rating of Baa3 or better by Moody’s (or its equivalent under any successor rating categories of Moody’s); a rating of BBB-or better by S&P (or its equivalent under any successor

S-13

rating categories of S&P); and the equivalent investment grade credit rating from any additional rating agency or rating agencies selected by us.

The term “Moody’s” means Moody’s Investors Service Inc.

The term “rating agency” means (1) each of Moody’s and S&P; and (2) if either of Moody’s or S&P ceases to rate the Senior Notes or fails to make a rating of the Senior Notes publicly available for reasons outside of our control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act, selected by us (as certified by a resolution of our board of directors) as a replacement agency for Moody’s or S&P, or both, as the case may be.

The term “S&P” means Standard & Poor’s Ratings Services, a division of McGraw-Hill, Inc.

The term “voting stock” of any specified “person” (as that term is used in Section 13(d)(3) of the Exchange Act) as of any date means the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person.

Book-Entry Issuance

The Depository Trust Company (“DTC”) will act as the initial securities depositary for the Senior Notes. The Senior Notes will be issued only as fully registered securities registered in the name of Cede & Co., DTC’s partnership nominee, or such other name as may be requested by an authorized representative of DTC. One or more fully registered global Note certificates will be issued, representing in the aggregate the total principal amount of the Senior Notes, and will be deposited with the trustee on behalf of DTC.

DTC, the world’s largest securities depositary, is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Banking Law, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC holds and provides asset servicing for U.S. and non-U.S. equity issues, corporate and municipal debt issues and money market instruments that DTC’s participants (“Direct Participants”) deposit with DTC. DTC also facilitates the post-trade settlement among Direct Participants of sales and other securities transactions in deposited securities, through electronic computerized book-entry transfers and pledges between Direct Participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct Participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. DTC is a wholly-owed subsidiary of The Depository Trust & Clearing Corporation (“DTCC”). DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies and clearing corporations that clear through or maintain a custodial relationship with a Direct Participant, either directly or indirectly (“Indirect Participants”). More information about DTC can be found at www.dtcc.com and www.dtc.org. Such information is not incorporated by reference in, and does not form a part of, this prospectus supplement or the accompanying prospectus.

Purchases of Senior Notes under the DTC system must be made by or through Direct Participants, which will receive a credit for the Senior Notes on DTC’s records. The ownership interest of each actual purchaser of Senior Notes (“Beneficial Owner”) is in turn to be recorded on the Direct and Indirect Participants’ records. Beneficial Owners will not receive written confirmation from DTC of their purchases. Beneficial Owners are, however, expected to receive written confirmations providing details of the transactions, as well as periodic statements of their holdings, from the Direct or Indirect Participants through which the Beneficial Owners purchased Senior Notes. Transfers of ownership interests in the Senior Notes are to be accomplished by entries made on the books of Direct and Indirect Participants acting on behalf of Beneficial Owners. Beneficial Owners will not receive certificates representing their ownership interests in Senior Notes, except in the event that use of the book-entry system for the Senior Notes is discontinued.

To facilitate subsequent transfers, all Senior Notes deposited by Direct Participants with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized

S-14

representative of DTC. The deposit of Senior Notes with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any changes in beneficial ownership. DTC has no knowledge of the actual Beneficial Owners of the Senior Notes. DTC’s records reflect only the identity of the Direct Participants to whose accounts such Senior Notes are credited, which may or may not be the Beneficial Owners. The Direct and Indirect Participants will remain responsible for keeping account of their holdings on behalf of their customers.

Conveyance of notices and other communications by DTC to Direct Participants, by Direct Participants to Indirect Participants, and by Direct Participants and Indirect Participants to Beneficial Owners will be governed by arrangements among them, subject to any statutory or regulatory requirements as may be in effect from time to time.

Redemption notices shall be sent to DTC. If less than all of the Senior Notes are being redeemed, DTC’s practice is to determine by lot the amount of interest of each Direct Participant in such Senior Notes to be redeemed.

Although voting with respect to the Senior Notes is limited, in those cases where a vote is required, neither DTC nor Cede & Co. (nor any other DTC nominee) will consent or vote with respect to the Senior Notes unless authorized by a Direct Participant in accordance with DTC’s procedures. Under its usual procedures, DTC mails an Omnibus Proxy to us as soon as possible after the record date. The Omnibus Proxy assigns Cede & Co.’s consenting or voting rights to those Direct Participants to whose accounts Senior Notes are credited on the record date (identified in a listing attached to the Omnibus Proxy).

Payments on the Senior Notes will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit Direct Participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the trustee on the relevant payment date in accordance with their respective holdings shown on DTC’s records. Payments by Direct or Indirect Participants to Beneficial Owners will be governed by standing instructions and customary practices, as is the case with securities held for the account of customers registered in “street name” and will be the responsibility of such Direct or Indirect Participant and not our responsibility or the responsibility of DTC, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment to Cede & Co. (or such other nominee as may be requested by an authorized representative of DTC) is our responsibility, disbursement of such payments to Direct Participants is the responsibility of DTC, and disbursement of such payments to the Beneficial Owners is the responsibility of Direct and Indirect Participants.

Except as provided herein, a Beneficial Owner of a global Senior Note will not be entitled to receive physical delivery of Senior Notes. Accordingly, each Beneficial Owner must rely on the procedures of DTC to exercise any rights under the Senior Notes. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global Senior Note.

DTC may discontinue providing its services as securities depository with respect to the Senior Notes at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor securities depository is not obtained, note certificates will be required to be printed and delivered to the holders of record. Additionally, the Company may decide to discontinue use of the system of book-entry transfers through DTC (or a successor securities depository) with respect to the Senior Notes. In that event, certificates for the Senior Notes will be printed and delivered to the applicable Direct or Indirect Participant.

Clearstream. Clearstream Banking, S.A. is incorporated under the laws of Luxembourg as a professional depositary. Clearstream holds securities for its participating organizations (“Clearstream Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Participants through electronic book-entry changes in accounts of Clearstream Participants, thereby eliminating the need for physical movement of certificates. Clearstream provides Clearstream Participants with, among other things, services for safekeeping, administration, clearance and establishment of internationally traded securities and securities lending and borrowing. Clearstream interfaces with domestic markets in several countries. As a professional depositary, Clearstream is subject to regulation by the Luxembourg Monetary Institute. Clearstream Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, and may include the underwriters. Indirect access to Clearstream is also available to others, such as banks, brokers,

S-15

dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Participant either directly or indirectly.

Distributions with respect to Senior Notes held beneficially through Clearstream will be credited to cash accounts of Clearstream Participants in accordance with its rules and procedures to the extent received by the U.S. Depositary for Clearstream.

Euroclear. Euroclear Bank SP./N.V. was created in 1968 to hold securities for participants of Euroclear (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Euroclear includes various other services, including securities lending and borrowing and interfaces with domestic markets in several markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”), under contract with Euro-clear Clearance Systems S.C., a Belgian cooperative corporation (the “Cooperative”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator, not the Cooperative. The Cooperative establishes policy for Euroclear on behalf of Euroclear Participants. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries and may include the underwriters. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Euroclear Operator is regulated and examined by the Belgian Banking Commission.

Links have been established among DTC, Clearstream and Euroclear to facilitate the initial issuance of the Senior Notes sold outside of the United States and cross-market transfers of the Senior Notes associated with secondary market trading.

Although DTC, Clearstream and Euroclear have agreed to the procedures provided below in order to facilitate transfers, they are under no obligation to perform these procedures, and these procedures may be modified or discontinued at any time.

Clearstream and Euroclear will record the ownership interests of their participants in much the same way as DTC, and DTC will record the total ownership of each of the U.S. agents of Clearstream and Euroclear, as participants in DTC. When Senior Notes are to be transferred from the account of a DTC participant to the account of a Clearstream participant or a Euroclear participant, the purchaser must send instructions to Clearstream or Euroclear through a participant at least one day prior to settlement. Clearstream or Euroclear, as the case may be, will instruct its U.S. agent to receive Senior Notes against payment. After settlement, Clearstream or Euroclear will credit its participant’s account. Credit for the Senior Notes will appear on the next day (European time).

Because settlement is taking place during New York business hours, DTC participants will be able to employ their usual procedures for sending Senior Notes to the relevant U.S. agent acting for the benefit of Clearstream or Euroclear participants. The sale proceeds will be available to the DTC seller on the settlement date. As a result, to the DTC participant, a cross-market transaction will settle no differently than a trade between two DTC participants.

When a Clearstream or Euroclear participant wishes to transfer Senior Notes to a DTC participant, the seller will be required to send instructions to Clearstream or Euroclear through a participant at least one business day prior to settlement. In these cases, Clearstream or Euroclear will instruct its U.S. agent to transfer these Senior Notes against payment for them. The payment will then be reflected in the account of the Clearstream or Euroclear participant the following day, with the proceeds back valued to the value date, which would be the preceding day, when settlement occurs in New York, if settlement is not completed on the intended value date, that is, the trade fails, proceeds credited to the Clearstream or Euroclear participant’s account will instead be valued as of the actual settlement date.

You should be aware that you will only be able to make and receive deliveries, payments and other communications involving the Senior Notes through Clearstream and Euroclear on the days when those clearing systems are open for business. Those systems may not be open for business on days when banks, brokers and other institutions are open for business in the United States. In addition, because of time zone

S-16

differences there may be problems with completing transactions involving Clearstream and Euroclear on the same business day as in the United States.

The information in this section concerning the operations and procedures of DTC, Clearstream Luxembourg and Euroclear has been obtained from sources that we believe to be reliable, but neither we nor the underwriters take responsibility for its accuracy. These operations and procedures are solely within the control of DTC, Euroclear and Clearstream Luxembourg, as applicable, and are subject to change by them from time to time. None of us, the underwriters or the trustee takes any responsibility for these operations and procedures, and you are urged to contact DTC, Euroclear, Clearstream Luxembourg or their respective participants to discuss these matters.

Defeasance

The Senior Notes will be subject to defeasance and discharge and to defeasance of certain covenants as set forth in the Indenture, see “Description of Debt Securities — Defeasance and Covenant Defeasance” in the accompanying prospectus.

S-17

CERTAIN UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

THIS SUMMARY IS OF A GENERAL NATURE AND IS INCLUDED HEREIN SOLELY FOR INFORMATION PURPOSES. THIS SUMMARY IS NOT INTENDED TO BE, AND SHOULD NOT BE, CONSTRUED TO BE LEGAL OR TAX ADVICE. NO REPRESENTATION WITH RESPECT TO THE CONSEQUENCES TO ANY PARTICULAR PURCHASER OF THE NOTES IS MADE. PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR OWN ADVISORS WITH RESPECT TO THEIR PARTICULAR CIRCUMSTANCES.

General

The following is a summary of certain U.S. federal income tax considerations of the purchase, ownership and disposition of a Senior Note. This summary applies to holders only if they are a beneficial owner of a Senior Note and acquire the Senior Note in this offering for a price equal to the issue price of the Senior Notes. The issue price of the Senior Notes is the first price at which a substantial amount of the Senior Notes is sold other than to bond houses, brokers or similar persons or organizations acting in the capacity of underwriters, placement agents or wholesalers. For purposes of this discussion, a “U.S. Holder” means a beneficial owner of a Senior Note that, for U.S. federal income tax purposes, is:


	•	a citizen or resident alien individual of the United States;

	•	a corporation (including for this purpose any other entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any State thereof or the District of Columbia;

	•	an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

	•	a trust (i) that is subject to the primary supervision of a court within the United States and under the control of one or more “United States persons” (as defined for U.S. federal income tax purposes), or (ii) that has a valid election in effect under applicable U.S. Treasury regulations to be treated as a “United States person.”

For the purposes of this discussion, a “non-U.S. Holder” means a beneficial owner of a Senior Note that, for U.S. federal income tax purposes, is an individual, corporation (including for this purpose any other entity treated as a corporation for U.S. federal income tax purposes), trust or estate that is not a U.S. Holder.

This summary is based on provisions of the Internal Revenue Code of 1986, as amended (the “Code”), Treasury regulations issued thereunder, and administrative and judicial interpretations thereof, all as of the date of this prospectus supplement and all of which are subject to change or differing interpretation (perhaps retroactively), and is for general information only. This summary addresses only beneficial owners of the Senior Notes that hold the Senior Notes as capital assets within the meaning of Section 1221 of the Code and does not represent a detailed description of the U.S. federal income tax consequences to prospective purchasers of the Senior Notes in light of their particular circumstances. In addition, it does not represent a detailed description of the U.S. federal income tax consequences applicable to prospective purchasers of the Senior Notes that are subject to special treatment under the U.S. federal income tax laws, such as taxpayers subject to the alternative minimum tax or the U.S. federal estate and gift tax, U.S. expatriates, financial institutions, partnerships or other pass-through entities, or investors in such entities, individual retirement and other tax deferred accounts, dealers and traders in securities or currencies, insurance companies, tax-exempt organizations, persons holding the Senior Notes as part of a conversion, constructive sale, wash sale or other integrated transaction or a hedge, straddle or synthetic security, and U.S. Holders whose functional currency is other than the U.S. dollar. We cannot assure holders that a change in law will not alter significantly the tax considerations that we describe in this summary.

If a U.S. or non-U.S. partnership (including for this purpose an entity or arrangement treated as a partnership for U.S. federal income tax purposes) holds the Senior Notes, the tax treatment of a partner generally will depend upon the status of the partner, the activities of the partnership and certain determinations made at the partner level. Non-U.S. partnerships also generally are subject to special tax documentation requirements.

S-18

U.S. Holders

Contingent Payments. In certain circumstances, we may be obligated to pay you amounts in excess of the stated interest and principal payable on the Senior Notes. The obligation to make such payments may implicate the provisions of Treasury regulations relating to “contingent payment debt instruments.” Under applicable Treasury regulations, the possibility of such amounts being paid will not cause the Senior Notes to be treated as contingent payment debt instruments if there is only a remote chance that these contingencies will occur or if such contingencies are considered to be incidental. If the Senior Notes were deemed to be contingent payment debt instruments, U.S. Holders might, among other things, be required to treat any gain recognized on the sale or other disposition of a Senior Notes as ordinary income rather than as capital gain, and the timing and amount of income inclusion may be different from the consequences discussed herein. Although the matter is not free from doubt, we intend to take the position that the likelihood that such payments will be made is remote or incidental and therefore the Senior Notes are not subject to the rules governing contingent payment debt instruments. This determination will be binding on a U.S. Holder unless such U.S. Holder explicitly discloses on a statement attached to such U.S. Holder’s timely filed U.S. federal income tax return for the taxable year that includes the acquisition date of the Senior Notes that such U.S. Holder’s determination is different. It is possible, however, that the Internal Revenue Service (the “IRS”) may take a contrary position from that described above, in which case the tax consequences to a U.S. Holder could differ materially and adversely from those described below. The remainder of this disclosure assumes that the Senior Notes will not be treated as contingent payment debt instruments.

Interest. It is expected and this discussion assumes that either the issue price of the Senior Notes will equal the stated principal amount of the Senior Notes or the Senior Notes will be issued with no more than a de minimis amount of original issue discount (“OID”). Therefore, a U.S. Holder will have ordinary interest income equal to the amount of interest paid or accrued on a Senior Note, includable in accordance with the U.S. Holder’s regular method of tax accounting for U.S. federal income tax purposes.

Dispositions. Generally, a sale, exchange, redemption or other taxable disposition of a Senior Note will result in capital gain or loss equal to the difference, if any, between the amount realized on the disposition (excluding amounts attributable to accrued and unpaid interest, which, as described above, will be taxed as ordinary income to the extent not previously included in gross income by the U.S. Holder) and the U.S. Holder’s tax basis in the Senior Note. A U.S. Holder’s tax basis for determining gain or loss on the disposition of a Senior Note generally will equal the purchase price of such Senior Note to such U.S. Holder. Such gain or loss will be long-term capital gain or loss if the Senior Note is held for more than one year as of the time of the disposition. The deductibility of capital losses is subject to limitations. The tax rate for long-term capital gains of non-corporate taxpayers is scheduled to increase for taxable years beginning on or after January 1, 2011. U.S. Holders should consult their tax advisors regarding the treatment of capital gains and losses.

Non-U.S. Holders

Interest. The United States generally imposes a 30 percent withholding tax on payments of interest to non-U.S. persons. The 30 percent (or lower applicable treaty rate) U.S. federal withholding tax will not apply to a non-U.S. Holder in respect of any payment of interest on the Senior Notes that is not effectively connected with the conduct of a U.S. trade or business provided that such non-U.S. Holder:


	•	does not actually (or constructively) own ten percent or more of the total combined voting power of all classes of our voting stock within the meaning of the Code and the U.S. Treasury regulations;

	•	is not a controlled foreign corporation that is related to us actually or constructively through sufficient stock ownership;

	•	is not a bank whose receipt of interest on the Senior Notes is described in section 881(c)(3)(A) of the Code; and

	•	(a) provides identifying information (i.e., name and address) to us or our paying agent on IRS Form W-8BEN (or successor form), and certifies, under penalty of perjury, that such non-U.S. Holder is not a U.S. person or (b) a financial institution holding the Senior Notes on behalf of such non-U.S. Holder certifies, under penalty

S-19


		of perjury, that it has received the applicable IRS Form W-8BEN (or successor form) from the beneficial owner and provides us with a copy.

If a non-U.S. Holder cannot satisfy the requirements described above, payments of interest made to such non-U.S. Holder will be subject to the 30 percent U.S. federal withholding tax, unless such non-U.S. Holder provides us with a properly executed (i) IRS Form W-8BEN (or successor form) claiming an exemption from or reduction in withholding under the benefit of an income tax treaty or (ii) IRS Form W-8ECI (or successor form) stating that interest paid on the Senior Note is not subject to withholding tax because it is effectively connected with such non-U.S. Holder’s conduct of a trade or business in the United States.

If a non-U.S. Holder is engaged in a trade or business in the United States and interest on the Senior Notes is effectively connected with the conduct of that trade or business (and, if required by an applicable income tax treaty, is attributable to a permanent establishment in the United States maintained by such non-U.S. Holder), such non-U.S. Holder, although exempt from the 30 percent withholding tax, generally will be subject to U.S. federal income tax on that interest on a net income basis in the same manner as if such non-U.S. Holder were a “United States person” as defined under the Code. In addition, if a non-U.S. Holder is a non-U.S. corporation, it may be subject to a branch profits tax equal to 30 percent (or lower applicable treaty rate) of its earnings and profits for the taxable year, subject to adjustments, that are effectively connected with the conduct by it of a trade or business in the United States. For this purpose, effectively connected interest on the Senior Notes will be included in earnings and profits.

Dispositions. Any gain realized on the disposition of a Senior Note by a non-U.S. Holder generally will not be subject to U.S. federal income or withholding tax unless (i) that gain is effectively connected with the non-U.S. Holder’s conduct of a trade or business in the United States (and, if required by an income tax treaty, is attributable to a U.S. permanent establishment maintained by such non-U.S. Holder), (ii) such non-U.S. Holder is an individual who is present in the United States for 183 days or more in the taxable year of that disposition and certain other conditions are met, or (iii) in the case of disposition proceeds representing accrued interest, the non-U.S. Holder cannot satisfy the requirements of the complete exemption from withholding tax described above (and the non-U.S. Holder’s U.S. federal income tax liability has not otherwise been fully satisfied through the U.S. federal withholding tax described above).

If a non-U.S. Holder’s gain is effectively connected with such non-U.S. Holder’s U.S. trade or business (and, if required by an applicable income tax treaty, is attributable to a U.S. permanent establishment maintained by such non-U.S. Holder), such non-U.S. Holder generally will be required to pay U.S. federal income tax on the net gain derived from the sale in the same manner as if it were a “United States person” as defined under the Code. If such a non-U.S. Holder is a corporation, such non-U.S. Holder may also, under certain circumstances, be subject to a branch profits tax at a 30% rate (or lower applicable treaty rate). If a non-U.S. Holder is subject to the 183-day rule described above, such non-U.S. Holder generally will be subject to U.S. federal income tax at a flat rate of 30% (or a reduced rate under an applicable treaty) on the amount by which capital gains allocable to U.S. sources (including gains from the sale, exchange, retirement or other disposition of the Senior Note) exceed capital losses allocable to U.S. sources, even though the non-U.S. Holder is not considered a resident alien under the Code.

Information Reporting and Backup Withholding

In general, information reporting requirements apply to interest paid to, and to the proceeds of a sale or other disposition of a Senior Note (including a redemption) by, certain U.S. Holders. In addition, backup withholding (currently at a rate of 28% and scheduled to increase to 31% as of January 1, 2011) may apply to a U.S. Holder unless such holder provides a correct taxpayer identification number and otherwise complies with applicable requirements of the backup withholding rules. Backup withholding generally does not apply to payments made to certain exempt U.S. persons.

In general, a non-U.S. Holder will not be subject to backup withholding and information reporting with respect to interest payments that we make to such holder provided that we have received from such holder the certification described above under “— Non-U.S. Holders — Interest” and neither we nor our paying agent has actual knowledge or reason to know that the non-U.S. Holder is a U.S. Holder. However, we or our paying agent may be required to report to the IRS and the non-U.S. Holder payments of interest on the Senior Notes and the

S-20

amount of tax, if any, withheld with respect to those payments. Copies of the information returns reporting such interest payments and any withholding may also be made available to the tax authorities in the country in which the non-U.S. Holder resides under the provisions of a treaty or agreement.

Payments of the proceeds of a sale or other disposition (including a redemption) of the Senior Notes made to or through a non-U.S. office of non-U.S. financial intermediaries that do not have certain enumerated connections with the United States generally will not be subject to information reporting or backup withholding. In addition, a non-U.S. Holder will not be subject to backup withholding or information reporting with respect to the proceeds of the sale or other disposition of a Senior Note within the United States or conducted through non-U.S. financial intermediaries with certain enumerated connections with the United States, if the payor receives the certification described above under “— Non-U.S. Holders — Interest” or such holder otherwise establishes an exemption, provided that the payor does not have actual knowledge or reason to know that the non-U.S. Holder is a United States person or the conditions of any other exemption are not, in fact, satisfied.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules will be allowed as a refund or credit against a holder’s U.S. federal income tax liability provided the required information is furnished by such holder to the IRS in a timely manner.

Recently Enacted United States Legislation

Recently enacted United States legislation generally imposes a tax of 3.8% on the “net investment income” of certain individuals, trusts and estates for taxable years beginning after December 31, 2012. Among other items, net investment income generally includes gross income from interest and net gain attributable to the disposition of certain property, less certain deductions. Prospective purchasers should consult their own tax advisors regarding the possible implications of this legislation in their particular circumstances.

THE PRECEDING SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSEQUENCES IS FOR GENERAL INFORMATION ONLY AND IS NOT LEGAL OR TAX ADVICE. ACCORDINGLY, PROSPECTIVE PURCHASERS SHOULD CONSULT THEIR OWN ADVISORS ON THE U.S. FEDERAL, STATE AND LOCAL, AND FOREIGN TAX CONSEQUENCES OF THEIR PURCHASE, OWNERSHIP, AND DISPOSITION OF THE NOTES, AND ON THE CONSEQUENCES OF ANY CHANGES IN APPLICABLE LAW.

S-21

UNDERWRITING

Subject to the terms and conditions of an underwriting agreement (the “Underwriting Agreement”), we have agreed to sell to each of the underwriters named below and each of the underwriters severally has agreed to purchase from us, the principal amount of the Senior Notes set forth opposite its name below:


	Principal Amount
Underwriter	of Senior Notes

Morgan Stanley & Co. Incorporated	$


Total	$	250,000,000

In the Underwriting Agreement, the underwriters have agreed, subject to the terms and conditions set forth therein, to purchase all of the Senior Notes offered hereby, if any of the Senior Notes are purchased.

The underwriters propose initially to offer the Senior Notes to the public at the public offering price set forth on the cover page of this prospectus supplement and to certain dealers at such price less a concession not in excess of % of the principal amount of the Senior Notes. The underwriters may allow, and such dealers may reallow, a discount not in excess of % of the principal amount of the Senior Notes to certain other dealers. After the initial public offering, the public offering price, selling concession and discount may be changed.

The Senior Notes are a new issue of securities with no established trading market. We do not intend to apply for listing of the Senior Notes on any national securities exchange or for quotation of the Senior Notes on any automated dealer quotation system. We have been advised by the underwriters that they presently intend to make a market in the Senior Notes after completion of the offering. However, they are under no obligation to do so and may discontinue any market-making activities at any time without any notice. We cannot assure the liquidity of the trading market for the Senior Notes or that an active public market for the Senior Notes will develop. If an active public trading market for the Senior Notes does not develop, the market price and liquidity of the Senior Notes may be adversely affected.

We have agreed to indemnify the underwriters against certain liabilities, including liabilities under the Securities Act.

Our expenses associated with the offer and sale of the Senior Notes are estimated to be $200,000, excluding underwriting discounts and commissions.

In order to facilitate the offering of the Senior Notes, the stabilizing manager may engage in transactions that stabilize, maintain or otherwise affect the price of the Senior Notes. Specifically, the stabilizing manager may sell more Senior Notes than it is obligated to purchase in connection with the offering of the Senior Notes, creating a naked short position for its own account. The stabilizing manager must close out any naked short position by purchasing Senior Notes in the open market. A naked short position is more likely to be created if the stabilizing manager is concerned that there may be downward pressure on the price of the Senior Notes in the open market after pricing that could adversely affect investors who purchase Senior Notes in the offering. As an additional means of facilitating the offering of the Senior Notes, the stabilizing manager may bid for, and purchase, these Senior Notes in the open market to stabilize the price of these notes. Finally, the stabilizing manager may also reclaim on behalf of the underwriting syndicate or for itself selling concessions allowed to an underwriter or a dealer for distributing these Senior Notes in the offering, if the stabilizing manager repurchases previously distributed Senior Notes to cover short positions or to stabilize the price of these Senior Notes. Any of these activities may raise or maintain the market price of these Senior Notes above independent market levels or prevent or retard a decline in the market price of these Senior Notes. The stabilizing manager is not required to engage in these activities, and may end any of these activities at any time. Morgan Stanley & Co. Incorporated, and its agents, will act as the stabilizing manager with respect to the Senior Notes.

In relation to each Member State of the European Economic Area which has implemented the Prospectus Directive, the underwriters, with effect from and including the date on which the Prospectus Directive is implemented in that Member State, have not made and will not make an offer of Senior Notes to the public in

S-22

that Member State except that they may, with effect from and including such date, make an offer of Senior Notes to the public in that Member State at any time:


	•	to legal entities which are authorized or regulated to operate in the financial markets or, if not so authorized or regulated, whose corporate purpose is solely to invest in securities;

	•	to any legal entity which has two or more of (1) an average of at least 250 employees during the last financial year; (2) a total balance sheet of more than €43,000,000; and (3) an annual net turnover of more than €50,000,000, as shown in its last annual or consolidated accounts; or

	•	in any other circumstances which do not require the publication by us of a prospectus pursuant to Article 3 of the Prospectus Directive.

For the purposes of the above, the expression an “offer of Senior Notes to the public” in relation to any Senior Notes in any Member State means the communication in any form and by any means of sufficient information on the terms of the offer and the Senior Notes to be offered so as to enable an investor to decide to purchase or subscribe the Senior Notes, as the same may be varied in that Member State by any measure implementing the Prospectus Directive in that Member State, and the expression Prospectus Directive means Directive 2003/7I/EC and includes any relevant implementing measure in that Member State.

The underwriters (i) have only communicated or caused to be communicated and will only communicate or cause to be communicated an invitation or inducement to engage in investment activity (within the meaning of Section 21 of the Financial Services and Markets Act 2000) in connection with the issue or sale of the Senior Notes in circumstances in which Section 21(1) of such Act does not apply to us and (ii) have complied and will comply with all applicable provisions of such Act with respect to anything done by them in relation to any Senior Notes in, from or otherwise involving the United Kingdom.

The underwriters and their affiliates have engaged and may in the future engage in transactions with, and, from time to time, have performed services for, us and our affiliates in the ordinary course of business, for which they have received and will receive customary compensation.

LEGAL MATTERS

The legality of the issuance of the Senior Notes will be passed upon for us by Warner Norcross & Judd LLP, Grand Rapids, Michigan, and for the underwriters by Mayer Brown LLP, Chicago, Illinois.

DESCRIPTION OF SECURITIES

This prospectus contains a summary of the debt securities, preferred stock, voting common stock, non-voting common stock, depositary shares, warrants and units that we may offer. These summaries are not meant to be a complete description of each security. However, this prospectus and the accompanying prospectus supplement contain the material terms and conditions for each security.

Any of the securities described herein and in a prospectus supplement may be issued separately or as part of a unit consisting of two or more securities, which may or may not be separable from one another.

DESCRIPTION OF DEBT SECURITIES

The following descriptions of the terms of the debt securities set forth certain general terms and provisions of the debt securities. The particular terms of the debt securities offered by any prospectus supplement and the extent, if any, to which such general provisions may apply to the debt securities so offered will be described in the prospectus supplement relating to such offered debt securities. To the extent that any prospectus supplement is inconsistent with any provision in this summary, the information contained in such prospectus supplement will

control. The debt securities that will be our senior debt securities will be issued under an Indenture dated as of September 23, 1999, as supplemented (the “Senior Debt Indenture”), between us and The Bank of New York Trust Company, N.A. (the “Senior Trustee”). The debt securities that will be our subordinated debt (“Subordinated Debt Securities”) will be issued under an Indenture (the “Subordinated Debt Indenture” and, collectively with the Senior Debt Indenture, the “Indentures”), to be entered into between us and a trustee to be determined (the “Subordinated Trustee”).

The Senior Debt Indenture has been filed with the SEC as an exhibit to our current report on Form 8-K filed October 6, 1999 and is incorporated herein by reference. The forms of the senior debt securities have been filed, or will be filed, with the SEC and incorporated by reference as exhibits to the registration statement and you should read them for the provisions that may be important to you. The forms of the Subordinated Debt Indenture and the Subordinated Debt Securities have been filed, or will be filed, with the SEC and incorporated by reference as exhibits to the registration statement and you should read them for the provisions that may be important to you. The Indentures are subject to and governed by the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

We have summarized certain provisions of the Indentures and the debt securities below. The summary is not complete and is subject to, and qualified in its entirety by reference to, the Indentures and the debt securities. Capitalized terms used in the summary have the meanings set forth in the applicable Indenture unless otherwise defined herein.

General

The debt securities will be our unsecured senior or subordinated obligations. The Indentures do not limit the amount of debt securities that we may issue thereunder and provide that we may issue debt securities under the Indentures from time to time in one or more series.

Reference is made to the prospectus supplement for the following terms of and information relating to the offered debt securities (to the extent such terms are applicable to such debt securities):


	•	classification as senior or subordinated debt securities;

	•	the specific designation, aggregate principal amount, purchase price and denomination of the offered debt securities;

Senior Debt

The debt securities and coupons, if any, appertaining thereto that will constitute part of our senior debt will be issued under the Senior Debt Indenture and will rank pari passu with all of our other unsecured and unsubordinated debt.

Limitation On Liens

The Senior Debt Indenture provides that we will not, and will not permit any of our Subsidiaries to, issue, assume or guarantee any indebtedness for money borrowed (“Debt”) if such Debt is secured by a mortgage, pledge, security interest or lien (a “Mortgage” or “Mortgages”) upon any of our Principal Properties or of any of our Subsidiaries’ Principal Properties or upon any shares of stock or other stock or other equity interest or indebtedness of any of our Subsidiaries (whether such property, shares of stock or other equity interest or indebtedness is now owned or hereafter acquired) which owns any Principal Property, without in any such case effectively providing that the debt securities shall be secured equally and ratably with (or prior to) such Debt; provided, however, that the foregoing restrictions shall not apply to:


	•	mortgages existing on the date the debt securities are originally issued or mortgages provided for under the terms of agreements existing on such date;

	•	mortgages on Current Assets securing Current Liabilities;

	•	mortgages on any property we or any of our Subsidiaries acquire, construct, alter or improve after the date of the Indenture that are created or assumed contemporaneously with or within one year after such acquisition


		(or, in the case of property constructed, altered or improved, after the completion and commencement of commercial operation of such property, whichever is later) to secure or provide for the payment of the purchase price or cost of such property, provided that in the case of any such construction, alteration or improvement the mortgages shall not apply to any property we or any of our Subsidiaries theretofore owned, other than (1) the property so altered or improved and (2) any theretofore unimproved real property on which the property so constructed or altered, or the improvement, is located;


	•	existing mortgages on property we or any of our Subsidiaries acquire (including mortgages on any property acquired from a Person that is consolidated with or merged with or into us or any of our Subsidiaries) or mortgages outstanding at the time any Person becomes one of our Subsidiaries that are not incurred in connection with such entity becoming one of our Subsidiaries;

	•	mortgages in our or any of our Subsidiaries’ favor;

	•	mortgages on any property (1) in favor of domestic or foreign governmental bodies to secure partial, progress, advance or other payments pursuant to any contract or statute, (2) securing indebtedness incurred to finance all or any part of the purchase price or cost of constructing, installing or improving the property subject to such mortgages, including mortgages to secure Debt of the pollution control or industrial revenue bond type, or (3) securing indebtedness issued or guaranteed by the United States, any state, any foreign country or any department, agency, instrumentality or political subdivision of any such jurisdiction; and

	•	any extension, renewal or replacement (or successive extensions, renewals or replacements), in whole or in part, of any mortgage referred to in the foregoing bullet points; provided, however, that the principal amount of Debt secured thereby shall not exceed the principal amount of Debt so secured at the time of such extension, renewal or replacement, together with the reasonable costs related to such extension, renewal or replacement, and that such extension, renewal or replacement shall be limited to all or a part of the property that secured the mortgage so extended, renewed or replaced (plus improvements on such property).

Notwithstanding the foregoing, we and any of our Subsidiaries may, without securing the debt securities, issue, assume or guarantee secured Debt (that would otherwise be subject to the foregoing restrictions) in an aggregate amount that, together with all other such secured Debt and the aggregate amount of our and our Subsidiaries’ Attributable Indebtedness deemed to be outstanding in respect of all Sale/Leaseback Transactions entered into pursuant to the provisions described below under “— Limitation on Sale/Leaseback Transactions” (excluding any such Sale/Leaseback Transactions the proceeds of which have been applied in accordance with clauses (2) or (3) under the “— Limitation on Sale/Leaseback Transactions” covenant described below), does not exceed 10% of the Consolidated Net Worth, as shown on a consolidated balance sheet as of a date not more than 90 days prior to the proposed transaction we prepare in accordance with generally accepted accounting principles in the United States of America. Limitation On Sale/Leaseback Transactions

The Senior Debt Indenture provides that we will not, and will not permit any of our Subsidiaries to, enter into any Sale/Leaseback Transaction with any Person (other than us or one of our Subsidiaries) unless:


	•	at the time of entering into such Sale/Leaseback Transaction, we or such Subsidiary would be entitled to incur Debt, in a principal amount equal to the Attributable Indebtedness with respect to such Sale/Leaseback Transaction, secured by a mortgage on the property subject to such Sale/Leaseback Transaction, pursuant to the provisions of the covenant described under “— Limitation on Liens” without equally and ratably securing the debt securities pursuant to such provisions;

	•	after the date on which debt securities are first issued, and within a period commencing six months prior to the consummation of such Sale/Leaseback Transaction and ending six months after the consummation thereof, we or such Subsidiary shall have expended for property used or to be used in our or such Subsidiary’s ordinary course of business (including amounts expended for additions, expansions, alterations, repairs and improvements thereto) an amount equal to all or a portion of the net proceeds of such Sale/Leaseback Transaction, and we shall have elected to designate such amount as a credit against such Sale/Leaseback Transaction (with any such amount not being so designated to be applied as set forth in clause (3) below); or


	•	during the 12-month period after the effective date of such Sale/Leaseback Transaction, we shall have applied to the voluntary defeasance or retirement of debt securities or any of our pari passu indebtedness an amount equal to the net proceeds of the sale or transfer of the property leased in such Sale/Leaseback Transaction, which amount shall not be less than the fair value of such property at the time of entering into such Sale/Leaseback Transaction (adjusted to reflect any amount we expended as set forth in clause (2) above), less an amount equal to the principal amount of such debt securities and pari passu indebtedness we voluntarily defeased or retired within such 12-month period and not designated as a credit against any other Sale/Leaseback Transaction we or any of our Subsidiaries entered into during such period.

Unless otherwise specified in the prospectus supplement relating to a particular series of offered debt securities, the covenants applicable to the debt securities would not necessarily afford holders protection in the event that we are involved in a highly leveraged or other transaction, or in the event of a material adverse change in our financial position or results of operations. Unless otherwise specified in the prospectus supplement relating to a particular series of offered debt securities, the debt securities do not contain any other provisions that are designed to afford protection in the event that we are involved in a highly leveraged transaction.

Subordinated Debt

The debt securities and coupons, if any, attached to such debt securities that will constitute part of the Subordinated Debt Securities will be issued under the Subordinated Debt Indenture and will be subordinate and junior in right of payment, to the extent and in the manner set forth in the Subordinated Debt Indenture, to all of our Senior Indebtedness. The Subordinated Debt Indenture defines “Senior Indebtedness” as all of our indebtedness, including indebtedness we have guaranteed or assumed, for borrowed money or evidenced by bonds, debentures, notes, letters of credit, interest rate exchange agreements, currency exchange agreements, commodity forward contracts or other similar instruments, or indebtedness or obligations with respect to any lease of real or personal property whether existing on the date hereof or hereinafter incurred, and any guarantee, amendments, renewals, extensions, modifications and refundings of any such indebtedness or obligation, provided that Senior Indebtedness shall not include (1) obligations that, when incurred and without respect to any election under Section 1111(b) of Title 11, United States Code, were without recourse to the issuer, (2) our obligations to any of our Subsidiaries and (3) any other obligations which by the terms of the instrument creating or evidencing the same are specifically designated as not being senior in right of payment to the Subordinated Debt Securities.

In the event (1) of any insolvency or bankruptcy proceedings, or any receivership, liquidation or other similar proceedings including reorganization in respect of our company or a substantial part of our property, or (2) that (a) a default shall have occurred with respect to the payment of principal of (and premium, if any) or any interest on or other monetary amounts due and payable on any Senior Indebtedness or (b) there shall have occurred an event of default (other than a default in the payment of principal, premium, if any, or interest, or other monetary amounts due and payable) with respect to any Senior Indebtedness, as defined therein or in the instrument under which the same is outstanding, permitting the holder or holders thereof to accelerate the maturity thereof, and such default or event of default shall not have been cured or waived or shall not have ceased to exist, unless, in the case of a default under clause (b) above, the default with respect to the Senior Indebtedness is cured or waived, or 180 days pass after notice of the default is given to the holders of Senior Indebtedness (unless the maturity of such Senior Indebtedness has been accelerated), then the holders of all Senior Indebtedness shall first be entitled to receive payment of the full amount unpaid thereon, or provision shall be made, in accordance with the relevant Senior Indebtedness, for such payment in money or money’s worth, before the holders of any of the Subordinated Debt Securities or coupons are entitled to receive a payment on account of the principal of (and premium, if any) or any interest on the indebtedness evidenced by such Subordinated Debt Securities or of such coupons. No new period of suspension of payments under clause (b) above may be commenced by reason of the same event of default (or any other event of default that existed or was continuing on the date of the commencement of such period) within twelve months after the first such notice relating thereto.

Without limitation of the foregoing, upon any acceleration of the Subordinated Debt Securities because of an event of default, we must promptly notify the holders of Senior Indebtedness of such acceleration, and may not pay the Subordinated Debt Securities unless (A) 120 days pass after such acceleration and (B) the terms of the Subordinated Debt Indenture permit such payment at such time.

By reason of such subordination, in the event of our bankruptcy, insolvency or liquidation, our creditors who are holders of Senior Indebtedness and our general creditors may recover more, ratably, than holders of the Subordinated Debt Securities. Certain of our contingent obligations, including certain guarantees, letters of credit, interest rate exchange agreements, currency exchange agreements and commodity forward contracts, would constitute Senior Indebtedness if we became obligated to pay such contingent obligations.

We expect from time to time to incur additional indebtedness constituting Senior Indebtedness. The Subordinated Debt Indenture does not prohibit or limit the incurrence of additional Senior Indebtedness or any other indebtedness and does not require us to adhere to financial covenants or similar restrictions. To the extent we issue Subordinated Debt Securities, we refer you to the applicable prospectus supplement for the amount of Senior Indebtedness outstanding.

Conversion and Exchange

The terms, if any, on which debt securities of any series will be convertible into or exchangeable for our common stock or preferred stock, property or cash, or a combination of any of the foregoing, will be summarized in the prospectus supplement relating thereto. Such terms may include provisions for conversion or exchange, either on a mandatory basis, at the option of the holder, or at our option, in which case the number of our shares of common stock or preferred stock to be received by the holders of the debt securities would be calculated according to the factors and at such time as summarized in the related prospectus supplement. The prospectus supplement will also summarize the material federal income tax consequences applicable to such convertible or exchangeable debt securities.

Events of Default

An “Event of Default” is defined under each Indenture with respect to debt securities of any series issued under such Indenture as being:


	•	default in the payment of any interest on any debt security when it becomes due and payable, and continuance of such default for a period of 30 days;

	•	default in the payment of the principal of any debt security at its maturity;

	•	default in our performance (or our breach) of any of our covenants or agreements in such Indenture, continued for 90 days after we receive written notice;

	•	acceleration of, or any failure to pay at final maturity, any of our or our Subsidiaries’ Debt (other than the debt securities or Non-Recourse Indebtedness) in an aggregate amount in excess of $25 million if such acceleration is not rescinded or annulled, or such indebtedness shall not have been discharged, within 15 days after we receive written notice thereof; and

	•	certain events of our or of one of our Significant Subsidiaries’ bankruptcy, insolvency or reorganization.

Each Indenture provides that if an Event of Default, other than certain events with respect to our bankruptcy, insolvency or reorganization, shall occur and be continuing, then the Senior Trustee or the Subordinated Trustee, as the case may be, or the holders of not less than 25% in aggregate principal amount of the outstanding debt securities may, by a notice in writing to us (and to the Senior Trustee or the Subordinated Trustee, as the case may be, if given by the holders), declare the principal of the debt securities, and all accrued and unpaid interest thereon, to be due and payable immediately. If an Event of Default with respect to certain events of our bankruptcy, insolvency or reorganization shall occur and be continuing, then the principal on the debt securities, and all accrued and unpaid interest thereon, shall be due and payable immediately without any act on the part of the Senior Trustee or the Subordinated Trustee, as the case may be, or any holder.

The holders of not less than a majority in principal amount of the outstanding debt securities may, on behalf of the holders of all of the debt securities, waive any past default under the Indenture and its consequences, except a default (1) in respect of the payment of principal of or interest on the debt securities or (2) in respect of a covenant or provision that cannot be modified or amended without the consent of each holder.

Under each Indenture we are required to file annually with the Senior Trustee or the Subordinated Trustee, as the case may be, an officers’ certificate as to our compliance with all conditions and covenants. Each Indenture will provide that the Senior Trustee or the Subordinated Trustee, as the case may be, may withhold notice to the holders of the debt securities of any default (except payment defaults on the debt securities) if it considers it to be in the interest of such holders to do so.

Subject to the provisions of each Indenture relating to the duties of the Senior Trustee or the Subordinated Trustee, as the case may be, each Indenture provides that when an Event of Default occurs and is continuing, the Senior Trustee or the Subordinated Trustee, as the case may be, will be under no obligation to exercise any of its rights or powers under such Indenture at the request or direction of any of the holders, unless such holders shall have offered to the Senior Trustee or the Subordinated Trustee, as the case may be, reasonable security or indemnity. Subject to such provisions concerning the rights of the Senior Trustee or the Subordinated Trustee, as the case may be, the holders of a majority in aggregate principal amount of the outstanding debt securities will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the Senior Trustee or the Subordinated Trustee, as the case may be, or exercising any trust or power conferred on the Senior Trustee or the Subordinated Trustee, as the case may be, under such Indenture.

Consolidation, Merger and Sale of Assets

Each Indenture provides that we will not consolidate with or merge into any other corporation, or convey, transfer or lease, or permit one or more of our Significant Subsidiaries to convey, transfer or lease, all or substantially all of our property and assets on a consolidated basis, to any Person unless (1) either we are the continuing corporation or such corporation or Person assumes by supplemental indenture all of our obligations under such Indenture and the debt securities issued thereunder, (2) immediately after such transaction no Default or Event of Default shall exist and (3) the surviving corporation or such Person is a corporation, partnership or trust organized and validly existing under the laws of the United States of America, any state thereof or the District of Columbia.

Modification or Waiver

Each Indenture provides that we may modify and amend such Indenture, and the Senior Trustee or the Subordinated Trustee, as the case may be, may modify and amend such Indenture with the consent of the holders of not less than a majority in principal amount of the outstanding debt securities; provided that no such modification or amendment may, without the consent of each holder, among other things:


	•	change the maturity of the principal of, or any installment of interest on, the debt securities;

	•	reduce the principal amount of, or the rate of interest on, the debt securities;

	•	change the place or currency of payment of principal of, or interest on, the debt securities;

	•	impair the right to institute suit for the enforcement of any such payment on or after the maturity thereof;

	•	reduce the percentage of holders necessary to modify or amend such Indenture or to consent to any waiver thereunder or reduce the requirements for voting or quorum described below; or

	•	modify the foregoing requirements or reduce the percentage of outstanding debt securities necessary to waive any past default.


	•	to evidence the succession of another Person to our company and the assumption by such Person of our covenants contained in such Indenture and the debt securities;

	•	to add covenants of our company for the benefit of the holders or to surrender any right or power conferred upon our company;


	•	to add Events of Default;

	•	to secure the debt securities;

	•	to evidence and provide for the acceptance of appointment by a successor Senior Trustee or a successor Subordinated Trustee, as the case may be;

	•	to cure any ambiguity, defect or inconsistency in such Indenture; provided such action does not adversely affect the interests of the holders;

	•	to supplement any of the provisions of such Indenture to the extent necessary to permit or facilitate defeasance and discharge of the debt securities; provided such action shall not adversely affect the interests of the holders; or

	•	to conform with the requirements of the Trust Indenture Act.

Defeasance and Covenant Defeasance

We may, at our option and at any time, terminate our obligations with respect to the outstanding debt securities (“Defeasance”). Defeasance means that we will be deemed to have paid and discharged the entire indebtedness represented by the outstanding debt securities, except for (1) the rights of the holders of outstanding debt securities to receive payment in respect of the principal of and interest on such debt securities when such payments are due, (2) our obligations to issue temporary debt securities, register and transfer or exchange any debt securities, replace mutilated, destroyed, lost or stolen debt securities, maintain an office or agency for payments in respect of the debt securities and segregate and hold money in trust, (3) the rights, powers, trusts, duties and immunities of the Senior Trustee or the Subordinated Trustee, as the case may be, and (4) the Defeasance provisions of the applicable Indenture. In addition, we may, at our option and at any time, elect to terminate our obligations with respect to the debt securities (being primarily the restrictions described under “— Limitation on Liens” and “— Limitation on Sale/Leaseback Transactions”), and any omission to comply with such obligations will not constitute a Default or an Event of Default with respect to the debt securities (“Covenant Defeasance”).

In order to exercise either Defeasance or Covenant Defeasance:


	•	we must irrevocably deposit with the Senior Trustee or the Subordinated Trustee, as the case may be, in trust, for the benefit of the holders, cash in United States dollars, U.S. Government Obligations, or a combination thereof, in such amounts as will be sufficient, in the opinion of a nationally recognized firm of independent public accountants, to pay the principal of and interest on the outstanding debt securities to maturity;

	•	we must deliver to the Senior Trustee or the Subordinated Trustee, as the case may be, an opinion of counsel to the effect that the holders of the outstanding debt securities will not recognize income, gain or loss for federal income tax purposes as a result of such Defeasance or Covenant Defeasance, and will be subject to federal income tax on the same amounts, in the same manner and at the same times as would have been the case if such Defeasance or Covenant Defeasance had not occurred (in the case of Defeasance, such opinion must refer to and be based upon a ruling of the Internal Revenue Service issued, or a change in applicable federal income tax laws occurring, after the date hereof);

	•	no Default or Event of Default shall have occurred and be continuing on the date of such deposit or, insofar as the last bullet point under the first paragraph under “— Events of Default” is concerned, at any time during the period ending the 91st day after the date of deposit (it being understood that this condition shall not be deemed satisfied until the expiration of such period);

	•	such Defeasance or Covenant Defeasance shall not cause the Senior Trustee or the Subordinated Trustee, as the case may be, to have a conflicting interest (as defined by the Trust Indenture Act) with respect to any of our securities;

	•	such Defeasance or Covenant Defeasance shall not result in a breach or violation of, or constitute a default under, the applicable Indenture or any material agreement or instrument to which we are a party or by which we are bound; and


	•	we shall have delivered to the Senior Trustee or the Subordinated Trustee, as the case may be, an officers’ certificate and an opinion of counsel, each stating that all conditions precedent under the applicable Indenture to either Defeasance or Covenant Defeasance, as the case may be, have been complied with and that no violations under agreements governing any other outstanding Debt would result.

Satisfaction and Discharge

Each Indenture provides that it will be discharged and will cease to be of further effect (except as to any surviving rights of registration of transfer or exchange of the debt securities, as expressly provided for in such Indenture) as to all outstanding debt securities when (1) either (a) all the debt securities theretofore authenticated and delivered (except lost, stolen or destroyed debt securities which have been replaced or paid and debt securities for whose payment money or certain U.S. Government Obligations has theretofore been deposited in trust or segregated and held in trust by us and thereafter repaid to us or discharged from such trust) have been delivered to the Senior Trustee or the Subordinated Trustee, as the case may be, for cancellation or (b) all debt securities not theretofore delivered to the Senior Trustee or the Subordinated Trustee, as the case may be, for cancellation have become due and payable or will become due and payable at maturity within one year and we have irrevocably deposited or caused to be deposited with the Senior Trustee or the Subordinated Trustee, as the case may be, funds in an amount sufficient to pay and discharge the entire indebtedness on the debt securities not theretofore delivered to the Senior Trustee or the Subordinated Trustee, as the case may be, for cancellation, for principal of and interest on the debt securities to the date of deposit together with irrevocable instructions from us directing the Senior Trustee or the Subordinated Trustee, as the case may be, to apply such funds to the payment thereof at maturity; (2) we have paid or have caused to be paid all other sums payable under such Indenture by us; and (3) we have delivered to the Senior Trustee or the Subordinated Trustee, as the case may be, an officers’ certificate and an opinion of counsel stating that all conditions precedent under such Indenture relating to the satisfaction and discharge of such Indenture have been complied with.

Legal Ownership

Street Name and Other Indirect Holders

Investors who hold debt securities in “street name” through accounts at banks or brokers will generally not be recognized by us as legal holders of debt securities. Instead, we, the Senior Trustee and the Subordinated Trustee will recognize only the registered holder, bank or broker, or the financial institution the bank or broker uses to hold its debt securities. These intermediary banks, brokers and other financial institutions pass along principal, interest and other payments on the debt securities, either because they agree to do so in their customer agreements or because they are legally required to do so. Street name and other indirect holders should consult their banks or brokers for information on their procedures with respect to these matters.

Direct Holders

Our obligations, as well as the obligations of the Senior Trustee and the Subordinated Trustee and those of any third parties employed by us, the Senior Trustee and the Subordinated Trustee, under the debt securities run only to persons who are registered as holders of debt securities. As noted above, we do not have obligations to you if you hold in street name or other indirect means, either because you choose to hold debt securities in that manner or because the debt securities are issued in the form of global securities as described below. For example, once we make payment to the registered holder, we have no further responsibility for the payment even if that holder is legally required to pass the payment along to you as a street name customer but does not do so.

Global Securities

If we choose to issue debt securities in the form of global securities, the ultimate beneficial owners of global securities can only be indirect holders. We require that the global security be registered in the name of a financial institution we select. We also require that the debt securities included in the global security not be transferred to the name of any other direct holder unless the special circumstances described in the section “Forms of Securities” below occur. The financial institution that acts as the sole direct holder of the global security is called the depositary.

Any person wishing to own a security must do so indirectly by virtue of an account with a broker, bank or other financial institution that in turn has an account with the depositary. Each prospectus supplement will indicate whether a series of debt securities covered by that prospectus supplement will be issued only in the form of global securities.

The Trustees

The Indentures and provisions of the Trust Indenture Act incorporated by reference therein contain limitations on the rights of the Senior Trustee or the Subordinated Trustee, as the case may be thereunder, should the Senior Trustee or the Subordinated Trustee, as the case may be, become one of our creditors, to obtain payment of claims in certain cases. We may from time to time maintain bank accounts and have other customary banking relationships with and obtain credit facilities and lines of credit from the Senior Trustee or the Subordinated Trustee, in the ordinary course of business; provided, however, that if the Senior Trustee or the Subordinated Trustee, as the case may be, acquires any conflicting interest (as defined in Section 310(b) of the Trust Indenture Act), it must eliminate such conflict or resign. We have appointed the Senior Trustee, at the offices specified in the Senior Debt Indenture, as registrar, principal paying agent and transfer agent for the senior debt securities. We will appoint the Subordinated Trustee, at the offices specified in the Subordinated Debt Indenture, as registrar, principal paying agent and transfer agent for the Subordinated Debt Securities. In such capacities, the Senior Trustee or the Subordinated Trustee, as the case may be, will be responsible for, among other things, (1) maintaining a record of the aggregate holdings of global securities and accepting debt securities for exchange and registration of transfer, (2) ensuring that payments of principal of and interest on global securities and other debt securities received from us by the Senior Trustee or the Subordinated Trustee, as the case may be, are duly paid to The Depository Trust Company (“DTC”) or its nominee or the holders thereof, as the case may be, and (3) transmitting to us any notices from holders of debt securities. We will cause the transfer agent to act as a registrar. We may vary or terminate the appointment of the transfer agent or appoint additional or other transfer agents or approve any change in the office through which any transfer agent acts.

DESCRIPTION OF PREFERRED STOCK

Authorized Preferred Stock

Our restated certificate of incorporation authorizes us to issue 5,000,000 shares of preferred stock, par value $0.01 per share. We may issue shares of preferred stock from time to time in one or more series, without stockholder approval, when authorized by our board of directors.

Upon issuance of a particular series of preferred stock, our board of directors is authorized, to specify:


	•	the number of shares to be included in the series;

	•	the annual dividend rate for the series and any restrictions or conditions on the payment of dividends;

	•	the manner in which dividends are to be paid;

	•	the redemption price, if any, and the terms and conditions of redemption;

	•	any retirement or sinking fund provisions for the purchase or redemption of the series;

	•	if the series is convertible or exchangeable, the terms and conditions of conversion or exchange;

	•	the amounts payable to holders upon our liquidation, dissolution or winding up;

	•	the priority of such series;

	•	the voting rights of such series; and

	•	any other rights, preferences and limitations relating to the series.

The ability of our board of directors to authorize, without stockholder approval, the issuance of preferred stock with conversion and other rights, may adversely affect the rights of holders of our voting common stock, non-voting common stock or other series of preferred stock that may be outstanding.

No shares of our preferred stock are currently issued and outstanding. Five hundred thousand shares of preferred stock have been designated as Series A Junior Participating Preferred Stock reserved for issuance under the Rights Agreement, dated as of July 22, 1998, between us and Mellon Investor Services, L.L.C., as rights agent. See “Description of Common Stock — Stockholder Rights Plan” below.

Specific Terms of a Series of Preferred Stock

The preferred stock we may offer will be issued in one or more series. Shares of preferred stock, when issued against full payment of its purchase price, will be fully paid and non-assessable. Their par value or liquidation preference, however, will not be indicative of the price at which they will actually trade after their issue. If necessary, the prospectus supplement will provide a description of U.S. federal income tax consequences relating to the purchase and ownership of the series of preferred stock offered by that prospectus supplement.

The preferred stock will have the dividend, liquidation, redemption and voting rights discussed below, unless otherwise described in a prospectus supplement relating to a particular series. A prospectus supplement will discuss the following features of the series of preferred stock to which it relates:


	•	the designations and stated value per share;

	•	the number of shares offered;

	•	the amount of liquidation preference per share;

	•	the initial public offering price at which the preferred stock will be issued;

	•	the dividend rate, the method of its calculation, the dates on which dividends would be paid and the dates, if any, from which dividends would cumulate;

	•	whether dividends are to be paid in cash or other securities or property;

	•	any redemption or sinking fund provisions;

	•	the voting rights of the preferred stock;

	•	any conversion or exchange rights; and

	•	any additional dividend, liquidation, redemption, sinking fund and other rights, preferences, privileges, limitations and restrictions.

Rank

Unless otherwise stated in the prospectus supplement, the preferred stock will have priority over our voting and non-voting common stock with respect to dividends and distribution of assets, but will rank junior to all our outstanding indebtedness for borrowed money. Any series of preferred stock could rank senior, equal or junior to our other capital stock, as may be specified in a prospectus supplement, as long as our restated certificate of incorporation so permits.

Dividends

Holders of each series of preferred stock shall be entitled to receive cash dividends to the extent specified in the prospectus supplement when, as and if declared by our board of directors, from funds legally available for the payment of dividends. The rates and dates of payment of dividends of each series of preferred stock will be stated in the prospectus supplement. Dividends will be payable to the holders of record of preferred stock as they appear on our books on the record dates fixed by our board of directors. Dividends on any series of preferred stock may be cumulative or non-cumulative, as discussed in the prospectus supplement.

Convertibility and Exchangeability

Shares of a series of preferred stock may be convertible or exchangeable into shares of our common stock, another series of preferred stock or other securities or property. The conversion or exchange may be mandatory or optional. The applicable prospectus supplement will specify whether the preferred stock being offered has any conversion or exchange features, and will describe all the related terms and conditions.

Redemption

The terms, if any, on which shares of preferred stock of a series may be redeemed will be discussed in the prospectus supplement.

Liquidation

Upon any voluntary or involuntary liquidation, dissolution or winding up of the affairs of our company, holders of each series of preferred stock will be entitled to receive distributions upon liquidation in the amount described in the related prospectus supplement plus an amount equal to any accrued and unpaid dividends for the then-current dividend period (including any accumulation in respect of unpaid dividends for prior dividend periods, if dividends on that series of preferred stock are cumulative). These distributions will be made before any distribution is made on any securities ranking junior to the preferred stock with respect to liquidation, including our common stock. If the liquidation amounts payable relating to the preferred stock of any series and any other securities ranking on a parity regarding liquidation rights are not paid in full, the holders of the preferred stock of that series will share ratably in proportion to the full liquidation preferences of each security. Holders of our preferred stock will not be entitled to any other amounts from us after they have received their full liquidation preference.

Transfer Agent

The transfer agent for each series of preferred stock will be named and described in the prospectus supplement for that series.

DESCRIPTION OF COMMON STOCK

The following summary description of our common stock is based on the provisions of our restated certificate of incorporation and by-laws and the applicable provisions of the Delaware general corporation law. This information is qualified entirely by reference to the provisions of our restated certificate of incorporation, our by-laws and the Delaware general corporation law. For information on how to obtain copies of our restated certificate of incorporation and by-laws, see “Where You Can Find More Information” below.

Authorized Capital

We currently have authority to issue 180,000,000 shares of capital stock, consisting of 5,000,000 shares of preferred stock, $0.01 par value, 150,000,000 shares of voting common stock, $0.01 par value, and 25,000,000 shares of non-voting common stock, $0.01 par value. As of December 31, 2007, 116,128,572 shares of our voting common stock were issued and outstanding, and no shares of our non-voting common stock or preferred stock were issued or outstanding.

The rights of the holders of our voting and non-voting common stock discussed below are subject to the rights that our board of directors may from time to time confer on holders of our preferred stock issued in the future. These rights may adversely affect the rights of holders of our voting common stock, non-voting common stock, or both.

Requirements for Advance Notification or Stockholder Proposals and Nominations

Our by-laws contain provisions requiring that a stockholder deliver advance notice of any business that such stockholder intends to raise at an annual meeting of stockholders and providing for procedures to be followed if a stockholder wishes to nominate a person to be elected as a director. To be timely, the stockholder must give written notice to our Secretary not less than 90 days or more than 120 days prior to the first anniversary of the preceding

year’s annual meeting. If the date of the next annual meeting is more than 30 days before, or more than 60 days after, the first anniversary of the preceding year’s annual meeting, the stockholder must deliver notice to our Secretary not earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the day on which public announcement of the date of such meeting is first made.

The notice must provide information about the stockholder giving the notice and the beneficial owner, if any, on whose behalf the nomination or proposal is being made, each person whom the stockholder proposes to nominate for election or reelection as director, and the business to be brought before the meeting. In addition, if we plan to increase the size of our board of directors, and we do not publicly announce all of the nominees for election or specify the size of the increased board of directors at least 70 days prior to the first anniversary of the preceding year’s annual meeting, a stockholder will have 10 days following the date of our public announcement to give notice with respect to nominees for any new positions created by such increase.

Special Meetings

Subject to the rights of holders of preferred stock, special meetings of stockholders may be called only by our board of directors pursuant to a resolution approved by a majority of the total number of directors, or by a person or committee expressly so authorized by our board of directors pursuant to a resolution approved by a majority of the total number of directors. According to our by-laws, if we call a special meeting to elect directors to our board of directors, a stockholder may nominate individuals for election if such stockholder delivers notice to our Secretary not earlier than the 120th day prior to such special meeting and not later than the close of business on the later of the 90th day prior to such special meeting or the 10th day following the day on which public announcement is first made of the date of the special meeting and of the nominees proposed by our board of directors to be elected at such meeting.

Voting Rights

Each holder of our common stock is entitled to one vote per share in the election of directors and on all other matters submitted to a vote of stockholders, and does not have cumulative voting rights. In general, holders of our non-voting common stock do not have voting rights, other than those required by law. However, holders of non-voting common stock may vote as a separate class on amendments to the restated certificate of incorporation that adversely affect their powers, preferences or special rights as holders of non-voting common stock.

Conversion Rights

Qualified institutional investors who are subject to regulatory requirements that forbid or limit their right to own general voting stock may convert their common stock into non-voting common stock on a share-for-share basis as needed to satisfy applicable regulatory requirements, or directly purchase non-voting common stock because of such regulatory requirements. Thereafter, the non-voting common stock may be converted into common stock on a share-for-share basis in such circumstances as are permitted by applicable regulatory requirements.

Dividends

Subject to any preferential rights of any of our outstanding preferred stock, holders of our common stock and non-voting common stock, treated as a single class, are entitled to receive, based on the number of shares held, cash dividends when and as declared by our board of directors from funds legally available for such purpose.

Rights Upon Liquidation

If we liquidate, holders of our common stock and non-voting common stock, treated as a single class, are entitled to receive, based on the number of shares held, all of the assets available for distribution to stockholders after payment of all prior claims, including any preferential liquidation rights of any preferred stock outstanding at that time. The holders of our common stock and non-voting common stock do not have any redemption rights.

No Action by Written Consent

Subject to the rights of holders of preferred stock, any action required or permitted to be taken by our stockholders must be effected at an annual or special meeting of stockholders and may not be affected by any consent in writing by such stockholders.

Other Rights

The holders of our common stock and non-voting common stock do not have preemptive rights to subscribe to any additional shares of any class of our capital stock. All of our outstanding shares of common stock are, and, upon conversion or exchange, any issued shares of our common stock and/or non-voting common stock will be, fully paid and non-assessable. Our common stock and non-voting common stock do not have any sinking fund provisions.

Our voting common stock is listed for trading on the New York Stock Exchange under the symbol “BWA” and the transfer agent and registrar for our voting common stock is Mellon Investor Services, L.L.C.

Some Important Charter and Statutory Provisions

Our restated certificate of incorporation provides for the division of our board of directors into three classes of directors, each serving staggered, three-year terms. In addition, our restated certificate of incorporation and our by-laws provide that directors may be removed only for cause and only upon the affirmative vote of holders of at least 80% of our outstanding voting power. Our restated certificate of incorporation further provides generally that any alteration, amendment or repeal of its sections regarding the composition, election and classification of our board of directors requires the approval of the holders of at least 80% of our outstanding voting power.

Our restated certificate of incorporation also provides that when it is evaluating any proposal from another party to (1) make a tender offer for our equity securities, (2) merge or consolidate us with another corporation or (3) purchase or otherwise acquire substantially all of our properties and assets, our board of directors must give due consideration to all relevant factors, including the social and economic effects on our employees, customers, suppliers and other constituents and the communities in which we operate or are located.

Our restated certificate of incorporation provides that a director will not be personally liable for monetary damages to us or our stockholders for breach of fiduciary duty as a director, except for liability:


	•	for any breach of the director’s duty of loyalty to us or our stockholders;

	•	for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law;

	•	for paying a dividend or approving a stock repurchase or redemption in violation of Section 174 of the Delaware general corporation law; or

	•	for any transaction from which the director derived an improper personal benefit.

Our restated certificate of incorporation also provides that each of our current or former directors, officers, employees or agents, or each such person who is or was serving or who had agreed to serve at our request as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise (including the heirs, executors, administrators or estate of that person), will be indemnified by us to the fullest extent permitted by the Delaware general corporation law. Our restated certificate of incorporation also specifically authorizes us to enter into agreements with any person providing for indemnification greater or different than that provided by our restated certificate of incorporation.

These provisions may have the effect of deterring hostile takeovers or delaying changes in control of our company or our management.

We are subject to the provisions of Section 203 of the Delaware general corporation law. In general, the statute prohibits a publicly held Delaware corporation from engaging in a “business combination” with an “interested

stockholder” for a period of three years after the date of the transaction in which the person became an interested stockholder, unless:


	•	prior to that date, the board of directors approved either the business combination or the transaction that resulted in the stockholder becoming an interested stockholder;

	•	when the transaction that resulted in such person becoming an interested stockholder was completed, the interested stockholder owned at least 85% of the voting stock of the corporation outstanding at the time the transaction began, excluding, for purposes of determining the number of shares outstanding, shares owned by some directors or employee stock plans; or

	•	on or after the date the stockholder became an interested stockholder, the business combination is approved by the board of directors and authorized by the affirmative vote, and not by the written consent, of at least two-thirds of outstanding voting stock, excluding the stock owned by the interested stockholder.

For purposes of Section 203, a “business combination” includes a merger, asset sale, or other transaction resulting in a financial benefit to the interested stockholder. An “interested stockholder” is a person, other than the corporation and any direct or indirect majority-owned subsidiary of the corporation, who together with affiliates and associates, owns or, as an affiliate or associate, within three years prior, did own, 15% or more of the corporation’s outstanding voting stock.

Stockholder Rights Plan

On July 21, 1998, our board of directors adopted a stockholder rights plan and, on July 22, 1998, signed a rights agreement with Mellon Investor Services, L.L.C., as rights agent. A copy of our rights agreement has been filed as an exhibit to the registration statement of which this prospectus is a part and is incorporated by reference into this prospectus. Under our stockholder rights plan, one preferred stock purchase right is attached to each outstanding share of our common stock. We refer to these preferred stock purchase rights as the “rights.” Each share of common stock and each share of non-voting common stock issued in the future will also receive a right until the rights become exercisable. Until a right is exercised, the holder of a right does not have any additional rights as a stockholder. These rights will expire on July 22, 2008, unless they are previously redeemed or exchanged by us as described below. These rights trade automatically with our common stock and non-voting common stock and will separate from the common stock and non-voting common stock and become exercisable only under the circumstances described below.

In general, the rights will become exercisable when the first of the following events happen:

(1) ten calendar days after a public announcement that a person or group has acquired beneficial ownership of 20% or more of the sum of our outstanding common stock and non-voting common stock; or

(2) ten business days, or such other date determined by our board of directors, after the beginning of, or announcement of an intention to begin, a tender offer or exchange offer that would result in a person or group beneficially owning 20% or more of the sum of our outstanding common stock and non-voting common stock.

If the rights become exercisable, holders of the rights will be able to purchase from us one one-hundredth of a share of our Series A Junior Participating Preferred Stock at a price of $300, subject to adjustment. However, all rights owned by any persons or groups triggering the event shall be void. If a person or group acquires 20% or more of the sum of our outstanding common stock and non-voting common stock then each right will entitle the holder (other than the 20% or more person or group that triggered the rights) to purchase a number of shares of our common stock in respect of rights attached to our common stock, or a number of shares of our non-voting common stock in respect of rights attached to our non-voting common stock, in either case having a market value of two times the exercise price of the right.

If we are acquired in a merger or other business combination transaction, or 50% or more of our consolidated assets or earning power are sold after a person or group acquires 20% or more of the sum of our outstanding common stock and non-voting common stock, then each right will entitle the holder (other than the 20% or more person or group that triggered the rights) to purchase a number of shares of common stock of the surviving or acquiring corporation having a market value of two times the exercise price of the right.

At any time after a person or group has acquired beneficial ownership of 20% or more of our outstanding common stock and non-voting common stock, our board of directors may, at its option, exchange all or any part of the then outstanding and exercisable rights for shares of common stock or shares of Series A Preferred Stock at an exchange ratio of one share of common stock or one one-hundredth of a share of Series A Junior Participating Preferred Stock per right. However, our board of directors will not be empowered to affect such exchange at any time after any person or group becomes the beneficial owner of 50% or more of our outstanding common stock.

Our board of directors may redeem the rights for $.01 per right at any time before a person or group has acquired beneficial ownership of 20% or more of the sum of our outstanding common stock and non-voting common stock. Our board of directors may generally reduce the 20% trigger to the higher of (1) the largest percentage then known to our company beneficially owned by a person or group or (2) 10%, and may otherwise amend the rights at any time before a person or group has acquired beneficial ownership of 20% or more of the sum of our outstanding common stock and non-voting common stock. The rights will expire at the close of business on July 22, 2008 unless we redeem them before that date.

DESCRIPTION OF DEPOSITARY SHARES

Fractional Shares of Preferred Stock

We may elect to offer fractional interests in shares of our preferred stock instead of whole shares of preferred stock. If so, we will allow a depositary to issue to the public depositary shares, each of which will represent a fractional interest as described in the prospectus supplement, of a share of preferred stock.

Deposit Agreement

The shares of the preferred stock underlying any depositary shares will be deposited under a separate deposit agreement between us and a bank or trust company acting as depositary with respect to that series. The depositary will have its principal office in the United States and have a combined capital and surplus of at least $50,000,000. The prospectus supplement relating to a series of depositary shares will include the name and address of the depositary. Under the deposit agreement, each owner of a depositary share will be entitled, in proportion of its fractional interest in a share of the preferred stock underlying that depositary share, to all the rights and preferences of that preferred stock, including dividend, voting, redemption, conversion, exchange and liquidation rights.

Depositary shares will be evidenced by one or more depositary receipts issued under the deposit agreement.

Dividends and Other Distributions

The depositary will distribute all cash dividends or other cash distributions in respect of the preferred stock to each record depositary shareholder based on the number of the depositary shares owned by that holder on the relevant record date. The depositary will distribute only that amount which can be distributed without attributing to any depositary shareholders a fraction of one cent, and any balance not so distributed will be added to and treated as part of the next sum received by the depositary for distribution to record depositary shareholders.

If there is a distribution other than in cash, the depositary will distribute property to the entitled record depositary shareholders, unless the depositary determines that it is not feasible to make that distribution. In that case the depositary may, with our approval, adopt the method it deems equitable and practicable for making that distribution, including any sale of property and the distribution of the net proceeds from this sale to the concerned holders.

Each deposit agreement will also contain provisions relating to the manner in which any subscription or similar rights we offer to preferred stockholders of the relevant series will be made available to depositary shareholders.

Withdrawal of Stock

Upon surrender of depositary receipts at the depositary’s office, the holder of the relevant depositary shares will be entitled to the number of whole shares of the related preferred stock series and any money or other property

those depositary shares represent. Depositary shareholders will be entitled to receive whole shares of the related preferred stock series on the basis described in the prospectus supplement, but holders of those whole preferred stock shares will not afterwards be entitled to receive depositary shares in exchange for their shares. If the depositary receipts the holder delivers evidence a depositary share number exceeding the whole share number of the related preferred stock series to be withdrawn, the depositary will deliver to that holder a new depositary receipt evidencing the excess number of depositary shares.

Redemption and Liquidation

The terms on which the depositary shares relating to the preferred stock of any series may be redeemed, and any amounts distributable upon our liquidation, dissolution or winding up, will be described in the prospectus supplement.

Convertibility and Exchangeability

Voting

Upon receiving notice of any meeting at which preferred stockholders of any series are entitled to vote, the depositary will mail the information contained in that notice to the record depositary shareholders relating to those series of preferred stock. Each depositary shareholder on the record date will be entitled to instruct the depositary on how to vote the shares of preferred stock underlying that holder’s depositary shares. The depositary will vote the preferred stock shares underlying those depositary shares according to those instructions, and we will take reasonably necessary actions to enable the depositary to do so. If the depositary does not receive specific instructions from the depositary shareholders relating to that preferred stock, it will abstain from voting those preferred stock shares, unless otherwise discussed in the prospectus supplement.

Amendment and Termination of Deposit Agreement

We and the depositary may amend the depositary receipt form evidencing the depositary shares and the related deposit agreement. However, any amendment that significantly affects the rights of the depositary shareholders will not be effective unless holders of a majority of the outstanding depositary shares approve that amendment. We or the depositary may terminate a deposit agreement only if:


	•	we have redeemed or reacquired all outstanding depositary shares relating to the deposit agreement,

	•	all preferred stock of the relevant series has been withdrawn, or

	•	there has been a final distribution in respect of the preferred stock of any series in connection with our liquidation, dissolution or winding up and such distribution has been made to the related depositary shareholders.

Charges of Depositary

We will pay all charges of each depositary in connection with the initial deposit and any redemption of the preferred stock. Depositary shareholders will be required to pay any other transfer and other taxes and governmental charges and any other charges expressly provided in the deposit agreement to be for their accounts.

Title

We and each depositary and any of our respective agents may treat the registered owner of any depositary share as the absolute owner of that share, whether or not any payment in respect of that depositary share is overdue and despite any notice to the contrary, for any purpose. See “Forms of Securities” below.

Resignation and Removal of Depositary

A depositary may resign at any time by issuing us a notice of resignation, and we may remove any depositary at any time by issuing it a notice of removal. Resignation or removal will take effect upon the appointment of a successor depositary and its acceptance of appointment. That successor depositary must:


	•	be appointed within 60 days after delivery of the notice of resignation or removal,

	•	be a bank or trust company having its principal office in the United States, and

	•	have a combined capital and surplus of at least $50,000,000.

Miscellaneous

Each depositary will forward to the relevant depositary shareholders all our reports and communications that we are required to furnish to preferred stockholders of any series.

Neither we nor the depositary will be liable if either of us is prevented or delayed by law or any circumstance beyond its control in performing its obligations under any deposit agreement. Our obligations and the obligations of each depositary under any deposit agreement will be limited to performance in good faith of their duties under that agreement, and they will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares or preferred stock unless they are provided with satisfactory indemnity. They may rely upon written advice of counsel or accountants, or information provided by persons presenting preferred stock for deposit, depositary shareholders or other persons believed to be competent and on documents believed to be genuine.

DESCRIPTION OF WARRANTS

We may issue warrants for the purchase of our debt securities, preferred stock, common stock, depositary shares or units. Warrants may be issued independently or together with debt securities, preferred stock, common stock, depositary shares or units, and may be attached to or separate from those securities.

Warrant Agreements

Each series of warrants will be evidenced by certificates issued under a separate warrant agreement to be entered into between us and a bank that we select as warrant agent with respect to such series. The warrant agent will have its principal office in the U.S. and have a combined capital and surplus of at least $50,000,000.

Issuance In Series

The prospectus supplement relating to a series of warrants will mention the name and address of the warrant agent. The prospectus supplement will describe the terms of the series of warrants in respect of which this prospectus is being delivered, including:


	•	the offering price;

	•	the currency for which the warrants may be purchased;

	•	the designation and terms of the securities with which the warrants are issued and the number of warrants issued with each security or each principal amount of security;

	•	the date on which the warrants and the related securities will be separately transferable;

	•	in the case of warrants to purchase debt securities, the principal amount of debt securities that can be purchased upon exercise, and the price for purchasing those debt securities;

	•	in the case of warrants to purchase preferred stock, depositary shares or common stock, the number of depositary shares or shares of preferred stock or common stock, as the case may be, that can be purchased upon the exercise, and the price for purchasing those shares;


	•	in the case of warrants to purchase units upon exercise, the number and type of units that can be purchased upon exercise, and the price of those units;

	•	the dates on which the right to exercise the warrants will commence and expire;

	•	material U.S. federal income tax consequences of holding or exercising those warrants;

	•	the terms of the securities issuable upon exercise of those warrants; and

	•	any other terms of the warrants.

Warrant certificates may be exchanged for new warrant certificates of different denominations, may be presented for transfer registration, and may be exercised at the warrant agent’s corporate trust office or any other office indicated in the prospectus supplement. If the warrants are not separately transferable from the securities with which they were issued, this exchange may take place only if the certificates representing the related securities are also exchanged. Prior to warrant exercise, warrantholders will not have any rights as holders of the underlying securities, including the right to receive any principal, premium, interest, dividends, or payments upon our liquidation, dissolution or winding up or to exercise any voting rights.

Exercise of Warrants

Each warrant will entitle the holder to purchase the securities specified in the prospectus supplement at the exercise price mentioned in, or calculated as described in, the prospectus supplement. Unless otherwise specified in the prospectus supplement, warrants may be exercised at any time up to 5:00 p.m., New York time, on the expiration date mentioned in that prospectus supplement. After the close of business on the expiration date, unexercised warrants will become void.

Warrants may be exercised by delivery of the warrant certificate representing the warrants to be exercised, or in the case of global securities, as described below under “Forms of Securities,” by delivery of an exercise notice for those warrants, together with certain information, and payment to the warrant agent in immediately available funds, as provided in the prospectus supplement, of the required purchase amount. The information required to be delivered will be on the reverse side of the warrant certificate and in the prospectus supplement. Upon receipt of payment and the warrant certificate or exercise notice properly executed at the office indicated in the prospectus supplement, we will, in the time period the relevant warrant agreement provides, issue and deliver the securities purchasable upon such exercise. If fewer than all of the warrants represented by such warrant certificates are exercised, a new warrant certificate will be issued for the remaining amount of warrants.

If mentioned in the prospectus supplement, securities may be surrendered as all or part of the exercise price for warrants.

Antidilution Provisions

As will be provided in a prospectus supplement, in the case of warrants to purchase common stock or securities convertible into or exchangeable for common stock, the exercise price payable and the number of shares of common stock purchasable upon warrant exercise may be adjusted in certain events, including:


	•	the issuance of a stock dividend to common stockholders or a combination, subdivision or reclassification of common stock;

	•	the issuance of rights, warrants or options to all common and preferred stockholders entitling them to purchase common stock for an aggregate consideration per share less than the current market price per share of common stock;

	•	any distribution to our common stockholders of evidences of our indebtedness of assets, excluding cash dividends or distributions referred to above; and

	•	any other events mentioned in the prospectus supplement.

No adjustment in the number of shares or securities purchasable upon warrant exercise will be required until cumulative adjustments require an adjustment of at least 1% of such number. No fractional shares will be issued upon warrant exercise, but we will pay the cash value of any fractional shares otherwise issuable.

Modification

Unless provided otherwise in an applicable prospectus supplement, we and any warrant agent may amend any warrant agreement and the terms of the related warrants by executing a supplemental warrant agreement, without any such warrantholders’ consent, for the purpose of:


	•	curing any ambiguity, any defective or inconsistent provision contained in the warrant agreement, or making any other corrections to the warrant agreement that are not inconsistent with the provisions of the warrant certificates;

	•	evidencing the succession of another corporation to us and its assumption of our covenants contained in the warrant agreement and the warrants;

	•	appointing a successor depository, if the warrants are issued in the form of global securities;

	•	evidencing a successor warrant agent’s acceptance of appointment with respect to the warrants;

	•	adding to our covenants for the warrantholders’ benefit or surrendering any right or power we have under the warrant agreement;

	•	issuing warrants in definitive form, if such warrants are initially issued in the form of global securities; or

	•	amending the warrant agreement and the warrants as we deem necessary or desirable and that will not adversely affect the warrantholders’ interests in any material respect.

Unless provided otherwise in an applicable prospectus supplement, we and the warrant agent may also amend any warrant agreement and the related warrants by a supplemental agreement with the consent of the holders of a majority of the unexercised warrants affected by such amendment, for the purpose of adding, modifying or eliminating any of the warrant agreement’s provisions or of modifying the warrantholders’ rights. However, no such amendment that:


	•	reduces the number or amount of securities receivable upon warrant exercise;

	•	shortens the time period during which the warrants may be exercised;

	•	otherwise adversely affects the exercise rights of warrantholders in any material respect; or

	•	reduces the number of unexercised warrants the consent of holders of which is required for amending the warrant agreement or the related warrants

	•	may be made without the consent of each holder affected by that amendment.

Consolidation, Merger and Sale of Assets

Unless provided otherwise in an applicable prospectus supplement, each warrant agreement will provide that we may consolidate or merge with or into any other corporation or sell, lease, transfer or convey all or substantially all of our assets to any other corporation. However, any successor or acquirer of such assets must assume all of our obligations under the relevant warrant agreement and for the unexercised warrants, as appropriate, and we or that successor corporation must not immediately be in default under that warrant agreement.

Enforceability of Rights By Holders of Warrants

Each warrant agent will act solely as our agent under the relevant warrant agreement and will not assume any obligation or relationship of agency or trust for any warrantholder. A single bank or trust company may act as warrant agent for more than one issue of warrants. A warrant agent will have no duty or responsibility in case we default in performing our obligations under the relevant warrant agreement or warrant, including any duty or responsibility to initiate any legal proceedings or to make any demand upon us. Any warrantholder may, without the

warrant agent’s consent or consent of any other warrantholder, enforce by appropriate legal action its right to exercise that warrant.

Replacement of Warrant Certificates

We will replace any destroyed, lost, stolen or mutilated warrant certificate upon delivery to us and the relevant warrant agent of satisfactory evidence of the ownership of that warrant certificate and of its destruction, loss, theft or mutilation, and (in the case of mutilation) surrender of that warrant certificate to the relevant warrant agent, unless we have, or the warrant agent has, received notice that the warrant certificate has been acquired by a bona fide purchaser. That warrantholder will also be required to provide indemnity satisfactory to us and the relevant warrant agent before a replacement warrant certificate will be issued.

Title

We and the warrant agents and any of our respective agents may treat the registered holder of any warrant certificate as the absolute owner of the warrants evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the warrants so requested, despite any notice to the contrary. See “Forms of Secuirties” below.

DESCRIPTION OF UNITS

We may issue units comprised of one or more debt securities, shares of preferred stock, shares of common stock and warrants in any combination. Each unit will be issued so that the holder of the unit is also the holder of each security included in the unit. Thus, the holder of a unit will have the rights and obligations of a holder of each included security. The unit agreement under which a unit is issued may provide that the securities included in the unit may not be held or transferred separately, at any time or at any time before a specified date.

The prospectus supplement may describe:


	•	the designation and terms of the units and of the securities comprising the units, including whether and under what circumstances those securities may be held or transferred separately;

	•	any provisions of the governing unit agreement that differ from those described below; and

	•	any provisions for the issuance, payment, settlement, transfer or exchange of the units or of the securities comprising the units.

The provisions described in this section, as well as those described under “Description of Debt Securities,” “Description of Preferred Stock,” “Description of Common Stock” and “Description of Warrants,” will apply to each unit and to any debt security, preferred stock, common stock or warrant, respectively, included in each unit.

We may issue units in such amounts and in as many distinct series as we wish. This section summarizes terms of the units that apply generally to all series.

Unit Agreements

We will issue the units under one or more unit agreements to be entered into between us and a bank or other financial institution, as unit agent. We may add, replace or terminate unit agents from time to time. We will identify the unit agreement under which each series of units will be issued and the unit agent under that agreement in the prospectus supplement.

The following provisions will generally apply to all unit agreements unless otherwise stated in the prospectus supplement.

Enforcement of Rights

The unit agent under a unit agreement will act solely as our agent in connection with the units issued under that agreement. The unit agent will not assume any obligation or relationship of agency or trust for or with any holders of

those units or of the securities comprising those units. The unit agent will not be obligated to take any action on behalf of those holders to enforce or protect their rights under the units or the included securities.

Except as indicated in the next paragraph, a holder of a unit may, without the consent of the unit agent or any other holder, enforce its rights as holder under any security included in the unit, in accordance with the terms of that security and the indenture, warrant agreement or other instrument under which that security is issued. Those terms are described elsewhere in this prospectus under the sections relating to debt securities, preferred stock, common stock and warrants.

Notwithstanding the foregoing, a unit agreement may limit or otherwise affect the ability of a holder of units issued under that agreement to enforce its rights, including any right to bring a legal action, with respect to those units or any securities, other than debt securities, that are included in those units. Limitations of this kind will be described in the prospectus supplement.

Modification Without Consent of Holders

Unless provided otherwise in an applicable prospectus supplement, we and the applicable unit agent may amend any unit or unit agreement without the consent of any holder:


	•	to cure any ambiguity;

	•	to correct or supplement any defective or inconsistent provision; or

	•	to make any other change that we believe is necessary or desirable and will not adversely affect the interests of the affected holders in any material respect.

We do not need any approval to make changes that affect only units to be issued after the changes take effect. We may also make changes that do not adversely affect a particular unit in any material respect, even if they adversely affect other units in a material respect. In those cases, we do not need to obtain the approval of the holder of the unaffected unit; we need only obtain any required approvals from the holders of the affected units.

Modification With Consent of Holders

Unless provided otherwise in an applicable prospectus supplement, we may not amend any particular unit or a unit agreement with respect to any particular unit unless we obtain the consent of the holder of that unit, if the amendment would:


	•	impair any right of the holder to exercise or enforce any right under a security included in the unit if the terms of that security require the consent of the holder to any changes that would impair the exercise or enforcement of that right, or

	•	reduce the percentage of outstanding units or any series or class the consent of whose holders is required to amend that series or class, or the applicable unit agreement with respect to that series or class, as described below.

Unless provided otherwise in an applicable prospectus supplement, any other change to a particular unit agreement and the units issued under that agreement would require the following approval:


	•	If the change affects only the units of a particular series issued under that agreement, the change must be approved by the holders of a majority of the outstanding units of that series, or

	•	If the change affects the units of more than one series issued under that agreement, it must be approved by the holders of a majority of all outstanding units of all series affected by the change, with the units of all the affected series voting together as one class for this purpose.

These provisions regarding changes with majority approval also apply to changes affecting any securities issued under a unit agreement, as the governing document.

In each case, the required approval must be given by written consent.

Unit Agreements Will Not Be Qualified Under Trust Indenture Act

No unit agreement will be qualified as an indenture, and no unit agent will be required to qualify as a trustee, under the Trust Indenture Act. Therefore, holders of units issued under unit agreements will not have the protections of the Trust Indenture Act with respect to their units.

Title

We and the unit agents and any of our respective agents may treat the registered holder of any unit certificate as an absolute owner of the units evidenced by that certificate for any purpose and as the person entitled to exercise the rights attaching to the units so requested, despite any notice to the contrary. See “Forms of Securities” below.

FORMS OF SECURITIES

Each debt security, warrant, purchase contract and unit will be represented either by a certificate issued in definitive form to a particular investor or by one or more global securities representing the entire issuance of securities. Both certificated securities in definitive form and global securities may be issued either (1) in registered form, where our obligation runs to the holder of the security named on the face of the security or, if a registry is kept, the registered owner of the note in the registry, or (2) subject to the limitations explained below under “— Limitations on Issuance of Bearer Securities and Bearer Debt Warrants,” in bearer form, where our obligation runs to the bearer of the security. Definitive securities name you or your nominee as the owner of the security (other than definitive bearer securities, which the holder thereof will be the owner), and in order to transfer or exchange these securities or to receive payments other than interest or other interim payments, you or your nominee must physically deliver the securities to the trustee, registrar, paying agent or other agent, as applicable. Registered global securities name a depositary or its nominee as the owner of the debt securities, warrants, purchase contracts or units represented by these global securities (other than global bearer securities, which the holder thereof will be the owner). The depositary maintains a computerized system that will reflect each investor’s beneficial ownership of the securities through an account maintained by the investor with its broker/dealer, bank, trust company or other representative, as we explain more fully below.

Global Securities

Registered Global Securities

We may issue registered debt securities, warrants, purchase contracts and units in the form of one or more fully registered global securities that will be deposited with a depositary or its nominee identified in the applicable prospectus supplement and registered in the name of that depositary or nominee. In those cases, one or more registered global securities will be issued in a denomination or aggregate denominations equal to the portion of the aggregate principal or face amount of the securities to be represented by registered global securities. Unless and until it is exchanged in whole for securities in definitive registered form, a registered global security may not be transferred except as a whole by and among the depositary for the registered global security, the nominees of the depositary or any successors of the depositary or those nominees.

If not described below, any specific terms of the depositary arrangement with respect to any securities to be represented by a registered global security will be described in the prospectus supplement relating to those securities. We anticipate that the following provisions will apply to all depositary arrangements.

Ownership of beneficial interests in a registered global security will be limited to persons, called participants, that have accounts with the depositary or persons that may hold interests through participants. Upon the issuance of a registered global security, the depositary will credit, on its book entry registration and transfer system, the participants’ accounts with the respective principal or face amounts of the securities beneficially owned by the participants. Any dealers, underwriters or agents participating in the distribution of the securities will designate the accounts to be credited. Ownership of beneficial interests in a registered global security will be shown on, and the transfer of ownership interests will be effected only through, records maintained by the depositary, with respect to interests of participants, and on the records of participants, with respect to interests of persons holding through participants. The laws of some states may require that some purchasers of securities take physical delivery of these

securities in definitive form. These laws may impair your ability to own, transfer or pledge beneficial interests in registered global securities.

So long as the depositary, or its nominee, is the registered owner of a registered global security, that depositary or its nominee, as the case may be, will be considered the sole owner and holder of the securities represented by the registered global security for all purposes under the applicable indenture, warrant agreement, purchase contract or unit agreement. Except as described below, owners of beneficial interests in a registered global security will not be entitled to have the securities represented by the registered global security registered in their names, will not receive or be entitled to receive physical delivery of the securities in definitive form and will not be considered the owners or holders of the securities under the applicable indenture, warrant agreement, purchase contract or unit agreement. Accordingly, each person owning a beneficial interest in a registered global security must rely on the procedures of the depositary for that registered global security and, if that person is not a participant, on the procedures of the participant through which the person owns its interest, to exercise any rights of a holder under the applicable indenture, warrant agreement, purchase contract or unit agreement. We understand that under existing industry practices, if we request any action of holders or if an owner of a beneficial interest in a registered global security desires to give or take any action that a holder is entitled to give or take under the applicable indenture, warrant agreement, purchase contract or unit agreement, the depositary for the registered global security would authorize the participants holding the relevant beneficial interests to give or take that action, and the participants would authorize beneficial owners owning through them to give or take that action or would otherwise act upon the instructions of beneficial owners holding through them.

Principal, interest payments on debt securities, other amounts due under debt securities and any payments to holders with respect to warrants, purchase contract or units, represented by a registered global security registered in the name of a depositary or its nominee will be made to the depositary or its nominee, as the case may be, as the registered owner of the registered global security. None of us, the trustees, the warrant agents, the unit agents or any of our other agents, agent of the trustees or agent of the warrant agents or unit agents will have any responsibility or liability for any aspect of the records relating to payments made on account of beneficial ownership interests in the registered global security or for maintaining, supervising or reviewing any records relating to those beneficial ownership interests.

We expect that the depositary for any of the securities represented by a registered global security, upon receipt of any payment of principal, interest, other amounts or other distribution of underlying securities or other property to holders on that registered global security, will immediately credit participants’ accounts in amounts proportionate to their respective beneficial interests in that registered global security as shown on the records of the depositary. We also expect that payments by participants to owners of beneficial interests in a registered global security held through participants will be governed by standing customer instructions and customary practices, as is now the case with the securities held for the accounts of customers registered in “street name,” and will be the responsibility of those participants.

If the depositary for any of these securities represented by a registered global security is at any time unwilling or unable to continue as depositary or ceases to be a clearing agency registered under the Securities Exchange Act of 1934, and a successor depositary registered as a clearing agency under the Securities Exchange Act of 1934 is not appointed by us within 90 days, we will issue securities in definitive form in exchange for the registered global security that had been held by the depositary. In addition, the indenture permits us at any time and in our sole discretion to decide not to have any of the securities represented by one or more registered global securities. However, The Depository Trust Company, New York, New York has advised us that, under its current practices, it would notify its participants of our request, but will only withdraw beneficial interests from the global securities at the request of each DTC participant. We will issue securities in definitive form in exchange for the registered global security or all the securities representing those securities. Any securities issued in definitive form in exchange for a registered global security will be registered in the name or names that the depositary gives to the relevant trustee, warrant agent, unit agent or other relevant agent of ours or theirs. It is expected that the depositary’s instructions will be based upon directions received by the depositary from participants with respect to ownership of beneficial interests in the registered global security that had been held by the depositary.

Bearer Global Securities

The securities may also be issued in the form of one or more bearer global securities that will be deposited with a common depositary for the Euroclear System and Clearstream Banking, societe anonyme or with a nominee for the depositary identified in the prospectus supplement relating to those securities. The specific terms and procedures, including the specific terms of the depositary arrangement, with respect to any securities to be represented by a bearer global security will be described in the prospectus supplement relating to those securities.

Limitations on Issuance of Bearer Securities and Bearer Debt Warrants

In compliance with United States federal income tax laws and regulations, bearer securities, including bearer securities in global form, and bearer debt warrants will not be offered, sold, resold or delivered, directly or indirectly, in the United States or its possessions or to United States persons, as defined below, except as otherwise permitted by United States Treasury Regulations Section 1.163-5(c) (2) (i) (D). Any underwriters, agents or dealers participating in the offerings of bearer securities or bearer debt warrants, directly or indirectly, must agree that:


	•	they will not, in connection with the original issuance of any bearer securities or during the restricted period, as defined in United States Treasury Regulations Section 1.163-5(c) (2) (i) (D) (7) which we refer to as the “restricted period,” offer, sell, resell or deliver, directly or indirectly, any bearer securities in the United States or its possessions or to United States persons, other than as permitted by the applicable Treasury Regulations described above, and

	•	they will not, at any time, offer, sell, resell or deliver, directly or indirectly, any bearer debt warrants in the United States or its possessions or to United States persons, other than as permitted by the applicable Treasury Regulations described above.

In addition, any underwriters, agents or dealers must have procedures reasonably designed to ensure that their employees or agents who are directly engaged in selling bearer securities or bearer debt warrants are aware of the above restrictions on the offering, sale, resale or delivery of bearer securities or bearer debt warrants.

Bearer securities, other than temporary global debt securities and bearer securities that satisfy the requirements of United States Treasury Regulations Section 1.163-5(c)(2) (i)(D)(3)(iii) and any coupons appertaining thereto will not be delivered in permanent global form or definitive bearer form, and no interest will be aid thereon, unless we have received a signed certificate in writing, or an electronic certificate described in United States Treasury Regulations Section 1.163-5(c)(2)(i)(D)(3)(ii), stating that on the date of that certificate the relevant interest in the bearer security:


	•	is owned by a person that is not a United States person;

	•	is owned by a United States person that (a) is a foreign branch of a United States financial institution, as defined in applicable United States Treasury Regulations, which we refer to as a “financial institution,” purchasing for its own account or for resale, or (b) is acquiring the bearer security through a foreign branch of a United States financial institution and who holds the bearer security through that financial institution through that date, and in either case (a) or (b) above, each of those United States financial institutions agrees, on its own behalf or through its agent, that it will comply with the requirements of Section 165(j)(3)(A), (B) or (C) of the Internal Revenue Code of 1986 and the Treasury Regulations thereunder;

	•	or is owned by a United States or foreign financial institution for the purposes of resale during the restricted period and, whether or not also described in the first or second clause above, the financial institution certifies that it has not acquired the bearer security for purposes of resale directly or indirectly to a United States person or to a person within the United States or its possessions.

We will not issue bearer debt warrants in definitive form.

We will make payments on bearer securities and bearer debt warrants only outside the United States and its possessions except as permitted by the above Treasury Regulations.

Bearer securities, other than temporary global securities, and any coupons or talons issued with bearer securities will bear the following legend: “Any United States person who holds this obligation will be subject to

limitations under the United States income tax laws, including the limitations provided in sections 165(j) and 1287(a) of the Internal Revenue Code.” The sections referred to in this legend provide that, with exceptions, a United States person will not be permitted to deduct any loss, and will not be eligible for capital gain treatment with respect to any gain realized on the sale, exchange or redemption of that bearer security or coupon.

As used in this section, the term bearer securities includes bearer securities that are part of units and the term bearer debt warrants includes bearer debt warrants that are part of units. As used herein, the term “United States person” means a citizen or resident of the United States for United States federal income tax purposes, a corporation or partnership, including an entity treated as a corporation or partnership for United States federal income tax purposes, created or organized in or under the laws of the United States, or any state of the United States or the District of Columbia, or an estate or trust the income of which is subject to United States federal income taxation regardless of its source. As used herein, “United States” means the United States of America (including the states thereof and the District of Columbia) and “its possessions” include Puerto Rico, the U.S. Virgin Islands, Guam, American Samoa, Wake Island and the Northern Mariana Islands.

Form of Securities Included in Units

The form of any warrant included in a unit will correspond to the form of the unit and of any other security included in that unit.

PLAN OF DISTRIBUTION

We may sell the debt securities in and/or outside the United States: (1) through underwriters or dealers; (2) directly to one or more purchasers; or (3) through agents. The applicable prospectus supplement with respect to the debt securities will set forth the terms of the offering of the debt securities, including the name or names of any underwriters or agents, if any, the purchase price of the debt securities and the proceeds to us from such sale. In addition, the applicable prospectus supplement will set forth any delayed delivery arrangements, any underwriting discounts and other items constituting underwriters’ compensation, any initial public offering price and any discounts or concessions allowed or re-allowed or paid to dealers.

Any initial public offering price and any discount or concessions allowed or reallowed or paid to dealers may be changed from time to time.

If underwriters are used in the sale, the debt securities will be acquired by the underwriters for their own account and may be resold from time to time in one or more transactions including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of sale. The debt securities may be offered to the public either through underwriting syndicates represented by one or more managing underwriters or directly by one or more firms acting as underwriters. The underwriter or underwriters with respect to a particular underwritten offering of debt securities will be named in the prospectus supplement relating to such offering and, if an underwriting syndicate is used, the managing underwriter or underwriters will be set forth on the cover of such prospectus supplement. Unless otherwise set forth in the prospectus supplement relating thereto, the obligations of the underwriters to purchase the offered debt securities will be subject to conditions precedent and the underwriters will be obligated to purchase all the offered debt securities if any are purchased.

If dealers are used in the sale of debt securities in respect of which this prospectus is delivered, we will sell such debt securities to the dealers as principals. The dealers may then resell such debt securities to the public at varying prices to be determined by such dealers at the time of resale. The names of the dealers and the terms of the transaction will be set forth in the prospectus supplement relating thereto.

The debt securities may be sold through agents we designate from time to time. Any agent involved in the offer or sale of the debt securities in respect to which this prospectus is delivered will be named, and any commissions payable by us to such agent will be set forth, in the prospectus supplement relating thereto. Unless otherwise indicated in the prospectus supplement, any such agent will be acting on a best efforts basis for the period of its appointment.

We may sell the debt securities directly to institutional investors or others, who may be deemed to be underwriters within the meaning of the Securities Act of 1933, as amended, with respect to any resale thereof. The terms of any such sales, including the terms of any bidding or auction process, will be described in the prospectus supplement relating thereto.

Agents, dealers and underwriters may be entitled under agreements entered into with us to indemnification by us against certain civil liabilities, including liabilities under the Securities Act, or to contribution with respect to payments which such agents, dealers or underwriters may be required to make in respect thereof. Agents, dealers and underwriters may be our customers, engage in transactions with us, or perform services for us in the ordinary course of business. In connection with an offering, certain persons participating in such offering may engage in transactions that stabilize, maintain or otherwise affect the price of the debt securities. Specifically, such persons may overallot such offering, creating a syndicate short position. In addition, such persons may bid for, and purchase, the debt securities in the open market to cover syndicate shorts or to stabilize the price of the debt securities. Finally, such persons may reclaim selling concessions allowed for distributing the debt securities in an offering, if such persons repurchase previously distributed debt securities in syndicate covering transactions, in stabilization transactions or otherwise. Any of these activities may stabilize or maintain the market price of the debt securities above independent market levels. Such persons are not required to engage in these activities, and may end any of these activities at any time. The debt securities may or may not be listed on a national securities exchange. We cannot assure you as to the future liquidity of the trading market, if any, for any debt securities issued.
