USE OF PROCEEDS

     The net proceeds from the sale of the offered securities will be used for general corporate purposes unless we specify otherwise in the prospectus supplement or free writing prospectus applicable to a particular offering. General corporate purposes may include the repayment of debt, acquisitions, stock repurchases, capital expenditures, investments in subsidiaries and joint ventures, and additions to working capital. Net proceeds may be temporarily invested prior to use.

DESCRIPTION OF THE DEBT SECURITIES

     The following is a general description of the debt securities (the “Debt Securities”) that we may offer from time to time. The particular terms of the Debt Securities offered by any prospectus supplement and the extent, if any, to which the general provisions described below may apply will be described in the applicable prospectus supplement. Although our securities include securities denominated in U.S. dollars, we can choose to issue securities in any other currency, including the euro.

     The Debt Securities will be either senior Debt Securities or subordinated Debt Securities. We will issue the senior Debt Securities under the senior indenture between The Bank of New York, or any successor trustee, and USS. We will issue the subordinated Debt Securities under a subordinated indenture between The Bank of New York, or any successor trustee, and USS. The senior indenture and the subordinated indenture are collectively referred to in this prospectus as the indentures, and each of the trustee under the senior indenture and the trustee under the subordinated indenture are referred to in this prospectus as trustee.

     The following description is only a summary of the material provisions of the indentures. We urge you to read the appropriate indenture because it, and not this description, defines your rights as holders of the notes or bonds. See the information under the heading “Where You Can Find More Information” to contact us for a copy of the appropriate indenture.

     General

     The senior Debt Securities are unsubordinated obligations, will rank on par with all other debt obligations of USS and, unless otherwise indicated in the related Prospectus Supplement, will be unsecured. The subordinated Debt Securities will be subordinate, in right of payment to Senior Indebtedness. A description of the subordinated Debt Securities is provided below under “ — Subordinated Debt Securities”. The specific terms of any subordinated Debt Securities will be provided in the related Prospectus Supplement. For a complete understanding of the provisions pertaining to the subordinated Debt Securities, you should refer to the subordinated indenture attached as an exhibit to the Registration Statement.

     Terms

     The indentures do not limit the principal amount of debt we may issue.

     We may issue notes or bonds in traditional paper form, or we may issue a global security. The Debt Securities of any series may be issued in definitive form or, if provided in the related prospectus supplement, may be represented in whole or in part by a global security or securities, registered in the name of a depositary designated by USS. Each Debt Security represented by a global security is referred to as a “Book-Entry Security.”

     Debt Securities may be issued from time to time pursuant to this prospectus, and will be offered on terms determined by market conditions at the time of sale. Debt Securities may be issued in one or more series with the same or various maturities and may be sold at par, a premium or an original issue discount. Debt Securities sold at an original issue discount may bear no interest or interest at a rate that is below market rates. Unless otherwise provided in the prospectus supplement, Debt Securities denominated in U.S. dollars will be issued in denominations of $1,000 and integral multiples thereof.

     Please refer to the prospectus supplement for the specific terms of the Debt Securities offered including the following:

	1.		Designation of an aggregate principal amount, purchase price, denomination and whether senior or subordinated;
	2.		Date of maturity;
	3.		If other than U.S. currency, the currency for which the Debt Securities may be purchased;
	4.		The interest rate or rates and, if floating rate, the method of calculating interest;
	5.		The times at which any premium and interest will be payable;
	6.		The place or places where principal, any premium and interest will be payable;
	7.		Any redemption or sinking fund provisions or other repayment obligations;
	8.		Any index used to determine the amount of payment of principal of and any premium and interest on the Debt Securities;
	9.		The application, if any, of the defeasance provisions to the Debt Securities;
	10.		If other than the entire principal amount, the portion of the Debt Securities that would be payable upon acceleration of the maturity thereof;
	11.		Any obligation we may have to redeem, purchase or repay the Debt Securities at the option of a holder upon the happening

of any event and the terms and conditions of redemption, purchase or repayment;

	12.		Whether the Debt Securities will be issued in whole or in part in the form of one or more global securities, and in such case, the depositary for the global securities;
	13.		Any additional covenants applicable to the Debt Securities being offered;
	14.		Any additional events of default applicable to the Debt Securities being offered;
	15.		The terms of subordination, if applicable;
	16.		The terms of conversion, if applicable;
	17.		Any material provisions of the applicable indenture described in this prospectus that do not apply to the Debt Securities; and
	18.		Any other specific terms including any terms that may be required by or advisable under applicable law.

     Except with respect to Book-Entry Securities, Debt Securities may be presented for exchange or registration of transfer, in the manner, at the places and subject to the restrictions set forth in the Debt Securities and the prospectus supplement. Such services will be provided without charge, other than any tax or other governmental charge payable in connection therewith, but subject to the limitations provided in the indentures.

     Certain Covenants of USS in the indentures

     Payment

     USS will pay principal of and premium, if any, and interest on the Debt Securities at the place and time described in the Debt Securities. (Section 10.01) Unless otherwise provided in the prospectus supplement, USS will pay interest on any Debt Security to the person in whose name that security is registered at the close of business on the regular record date for that interest payment. (Section 3.07)

     Any money deposited with the trustee or any paying agent for the payment of principal of or any premium or interest on any Debt Security that remains unclaimed for two years after that amount has become due and payable will be paid to USS at its request. After this occurs, the holder of that security must look only to USS for payment of that amount and not to the trustee or paying agent. (Section 10.03)

     Merger and Consolidation

     USS will not merge or consolidate with any other entity or sell or convey all or substantially all of its assets to any person, firm, corporation or other entity, except that USS may merge or consolidate with, or sell or convey all or substantially all of its assets to, any other entity if (i) USS is the continuing entity or the successor entity (if other than USS) is organized and existing under the laws of the United States of America, a State thereof or the District of Columbia and such entity expressly assumes payment of the principal and interest on all the Debt Securities, and the performance and observance of all of the covenants and conditions of the applicable indenture to be performed by USS and (ii) there is no default under the applicable indenture. Upon such a succession, USS will be relieved from any further obligations under the applicable indenture. For purposes of this paragraph, “substantially all of its assets” means, at any date, a portion of the non-current assets reflected in USS’ consolidated balance sheet as of the end of the most recent quarterly period that represents at least 66-2/3% of the total reported value of such assets. (Section 8.01)

     Waiver of Certain Covenants

     Unless otherwise provided in the prospectus supplement, USS may, with respect to the Debt Securities of any series, omit to comply with any covenant provided in the terms of those Debt Securities if, before the time for such compliance, holders of at least a majority in principal amount of the outstanding Debt Securities of that series waive such compliance in that instance or generally.

     Events of Default

     An Event of Default occurs with respect to any series of Debt Securities when: (i) USS defaults in paying interest on the Debt Securities of such series when due, continuing for 30 days; (ii) USS defaults in paying principal of or premium, if any, on any of the Debt Securities of such series when due; (iii) USS defaults in making deposits into any sinking fund payment with respect to any Debt Security of such series when due, continuing for 30 days; (iv) failure by USS in the performance of any other covenant or warranty in the Debt Securities of such series or in the applicable indenture continues for a period of 90 days after notice of such failure as provided in that indenture; (v) certain events of bankruptcy, insolvency, or reorganization occur; or (vi) any other Event of Default

provided with respect to Debt Securities of that series. (Section 5.01)

     USS is required annually to deliver to the trustee officers’ certificates stating whether or not the signers have any knowledge of any default in the performance by USS of certain covenants. (Section 10.04)

     If an Event of Default regarding Debt Securities of any series issued under the indentures should occur and be continuing, either the trustee or the holders of not less than 25% in the principal amount of outstanding Debt Securities of such series may declare each Debt Security of that series due and payable (Section 5.02).

     No Event of Default regarding one series of Debt Securities issued under an indenture is necessarily an Event of Default regarding any other series of Debt Securities.

     Holders of a majority in principal amount of the outstanding Debt Securities of any series will be entitled to control certain actions of the trustee under the indentures and to waive certain past defaults regarding such series (Sections 5.12 and 5.13). The trustee generally cannot be required by any of the holders of Debt Securities to take any action, unless one or more of such holders shall have provided to the trustee security or indemnity reasonably satisfactory to it (Section 6.02).

     If an Event of Default occurs and is continuing regarding a series of Debt Securities, the trustee may use any sums that it holds under the relevant indenture for its own reasonable compensation and expenses incurred prior to paying the holders of Debt Securities of such series (Section 5.06).

     Before any holder of any series of Debt Securities may institute action for any remedy, except payment on such holder’s Debt Security when due, the holders of not less than 25% in principal amount of the Debt Securities of that series outstanding must request the trustee to take action. Holders must also offer and give the trustee satisfactory security and indemnity against liabilities incurred by the trustee for taking such action (Sections 5.07 and 5.08).

     Modification of the Indentures

     Each indenture contains provisions permitting USS and the trustee to modify that indenture or enter into or modify any supplemental indenture without the consent of the holders of the Debt Securities in regard to matters as shall not adversely affect the interests of the holders of the Debt Securities, including, without limitation, the following: (a) to evidence the succession of another corporation to USS; (b) to add to the covenants of USS further covenants for the benefit or protection of the holders of any or all series of Debt Securities or to surrender any right or power conferred upon USS by that indenture; (c) to add any additional events of default with respect to all or any series of Debt Securities; (d) to add to or change any of the provisions of that indenture to facilitate the issuance of Debt Securities in bearer form with or without coupons, or to permit or facilitate the issuance of Debt Securities in uncertificated form; (e) to add to, change or eliminate any of the provisions of that indenture in respect of one or more series of Debt Securities thereunder, under certain conditions designed to protect the rights of any existing holder of those Debt Securities; (f) to secure all or any series of Debt Securities; (g) to establish the forms or terms of the Debt Securities of any series; (h) to evidence the appointment of a successor trustee and to add to or change provisions of that indenture necessary to provide for or facilitate the administration of the trusts under that indenture by more than one trustee; or (i) to cure any ambiguity, to correct or supplement any provision of that indenture which may be defective or inconsistent with another provision of that indenture or to make other amendments that do not adversely affect the interests of the holders of any series of Debt Securities in any material respect. (Section 9.01)

     USS and the trustee may otherwise modify each indenture or any supplemental indenture with the consent of the holders of not less than a majority in aggregate principal amount of each series of Debt Securities affected thereby at the time outstanding, except that no such modifications shall, without the consent of the holder of each Debt Security affected thereby (i) extend the fixed maturity of any Debt Securities or any installment of interest or premium on any Debt Securities, or reduce the principal amount thereof or reduce the rate of interest or premium payable upon redemption, or reduce the amount of principal of an original issue discount Debt Security or any other Debt Security that would be due and payable upon a declaration of acceleration of the maturity thereof, or change the currency in which the Debt Securities are payable or impair the right to institute suit for the enforcement of any payment after the stated maturity thereof or the redemption date, if applicable, or adversely affect any right of the holder of any Debt Security to require USS to repurchase that security, (ii) reduce the percentage of Debt Securities of any series, the consent of the holders of which is required for any waiver or supplemental indenture, (iii) modify the provisions of that indenture relating to the waiver of past defaults or the waiver or certain covenants or the provisions described under “Modification of the Indentures,” except to increase any percentage set forth in those provisions or to provide that other provisions of that indenture may not be modified without the consent of the holder of each Debt Security affected thereby, (iv) change any obligation of USS to maintain an office or agency, (v) change any obligation of USS to pay additional amounts, (vi) adversely affect the right of repayment or repurchase at the option of the Holder, or (vii) reduce or postpone any sinking fund or similar provision. (Section 9.02)

     Satisfaction and Discharge; Defeasance and Covenant Defeasance

     Each indenture shall be satisfied and discharged if (i) USS shall deliver to the trustee all Debt Securities then outstanding for cancellation or (ii) all Debt Securities not delivered to the trustee for cancellation shall have become due and payable, are to become due and payable within one year or are to be called for redemption within one year and USS shall deposit an amount sufficient to pay the principal, premium, if any, and interest to the date of maturity, redemption or deposit (in the case of Debt Securities that have become due and payable), provided that in either case USS shall have paid all other sums payable under that indenture. (Section 4.01)

     Each indenture provides, if such provision is made applicable to the Debt Securities of a series, (i) that USS may elect either (A) to defease and be discharged from any and all obligations with respect to any Debt Security of such series (except for the obligations to register the transfer or exchange of such Debt Security, to replace temporary or mutilated, destroyed, lost or stolen Debt Securities, to maintain an office or agency in respect of the Debt Securities and to hold moneys for payment in trust) (“defeasance”) or (B) to be released from its obligations with respect to such Debt Security under Section 8.01 of that indenture (being the restrictions described above under “Certain Covenants of USS in the indentures”) together with additional covenants that may be included for a particular series and (ii) that Sections 5.01(3), 5.01(4) (as to Section 8.01) and 5.01(7), as described in clauses (iii), (iv) and (vi) under “Events of Default,” shall not be Events of Default under that indenture with respect to such series (“covenant defeasance”), upon the deposit with the trustee (or other qualifying trustee), in trust for such purpose, of money certain U.S. government obligations and/or, in the case of Debt Securities denominated in U.S. dollars, certain state and local government obligations which through the payment of principal and interest in accordance with their terms will provide money, in an amount sufficient to pay the principal of (and premium, if any) and interest on such Debt Security, on the scheduled due dates. In the case of defeasance, the holders of such Debt Securities are entitled to receive payments in respect of such Debt Securities solely from such trust. Such a trust may only be established if, among other things, USS has delivered to the trustee an Opinion of Counsel (as specified in the indentures) to the effect that the holders of the Debt Securities affected thereby 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. Such Opinion of Counsel, in the case of defeasance under clause (A) above, must refer to and be based upon a ruling of the Internal Revenue Service or a change in applicable Federal income tax law occurring after the date of the indentures. (Section 13.04)

     Record Dates

     The indentures provide that in certain circumstances USS may establish a record date for determining the holders of outstanding Debt Securities of a Series entitled to join in the giving of notice or the taking of other action under the applicable indenture by the holders of the Debt Securities of such Series.

     Subordinated Debt Securities

     Although the senior indenture and the subordinated indenture are generally similar and many of the provisions discussed above pertain to both senior and subordinated Debt Securities, there are many substantive differences between the two. This section discusses some of those differences.

     Subordination

     Subordinated Debt Securities will be subordinate, in right of payment, to all Senior Indebtedness. “Senior Indebtedness” is defined to mean, with respect to USS, the principal, premium, if any, and interest, fees, charges, expenses, reimbursement obligations, guarantees and other amounts owing with respect to all Indebtedness of USS (including Indebtedness of others guaranteed by USS), whether outstanding on the date of the indenture or the date Debt Securities of any series are issued under the indenture or thereafter created, incurred or assumed, unless in any case in the instrument creating or evidencing any such Indebtedness or obligation or pursuant to which the same is outstanding it is provided that such Indebtedness or obligation is not superior in right of payment to the subordinated Debt Securities or it is provided that such obligation is subordinated to Senior Indebtedness to substantially the same extent as the subordinated Debt Securities are subordinated to Senior Indebtedness.

     Terms of Subordinated Debt Securities may contain Conversion or Exchange Provisions

     The Prospectus Supplement for a particular series of subordinated Debt Securities will describe the specific terms discussed above that apply to the subordinated Debt Securities being offered thereby as well as any applicable conversion or exchange provisions.

     Modification of the Indenture Relating to Subordinated Debt Securities

     The subordinated indenture may be modified by USS and the trustee without the consent of the Holders of the subordinated Debt

Securities for one or more of the purposes discussed above under “—Modification of the indentures.” USS and the trustee may also modify the subordinated indenture to make provision with respect to any conversion or exchange rights for a given issue of subordinated Debt Securities.

     Governing Law

     The laws of the State of New York govern each indenture and will govern the Debt Securities. (Section 1.12)

     Book-Entry Securities

     The following description of book-entry securities will apply to any series of Debt Securities issued in whole or in part in the form of one or more global securities except as otherwise described in the prospectus supplement.

     Book-entry securities of like tenor and having the same date will be represented by one or more global securities deposited with and registered in the name of a depositary that is a clearing agent registered under the Exchange Act. Beneficial interests in book-entry securities will be limited to institutions that have accounts with the depositary (“participants”) or persons that may hold interests through participants. Ownership of beneficial interests by participants will only be evidenced by, and the transfer of that ownership interest will only be effected through, records maintained by the depositary. Ownership of beneficial interests by persons that hold through participants will only be evidenced by, and the transfer of that ownership interest within such participant will only be effected through, records maintained by the participants. The laws of some jurisdictions require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability to transfer beneficial interests in a global security.

     Payment of principal of and any premium and interest on book-entry securities represented by a global security registered in the name of or held by a depositary will be made to the depositary, as the registered owner of the global security. Neither USS, the trustee nor any agent of USS or the trustee will have any responsibility or liability for any aspect of the depositary’s records or any participant’s records relating to or payments made on account of beneficial ownership interests in a global security or for maintaining, supervising or reviewing any of the depositary’s records or any participant’s records relating to the beneficial ownership interests. Payments by participants to owners of beneficial interests in a global security held through such participants will be governed by the depositary’s procedures, as is now the case with securities held for the accounts of customers registered in “street name,” and will be the sole responsibility of such participants.

     A global security representing a book-entry security is exchangeable for definitive Debt Securities in registered form, of like tenor and of an equal aggregate principal amount registered in the name of, or is transferable in whole or in part to, a person other than the depositary for that global security, only if (a) the depositary notifies USS that it is unwilling or unable to continue as depositary for that global security or the depositary ceases to be a clearing agency registered under the Exchange Act, (b) there shall have occurred and be continuing an Event of Default with respect to the Debt Securities of that Series or (c) other circumstances exist that have been specified in the terms of the Debt Securities of that Series. Any global security that is exchangeable pursuant to the preceding sentence shall be registered in the name or names of such person or persons as the depositary shall instruct the trustee. It is expected that such instructions may be based upon directions received by the depositary from its participants with respect to ownership of beneficial interests in such global security.

     Except as provided above, owners of beneficial interests in a global security will not be entitled to receive physical delivery of Debt Securities in definitive form and will not be considered the holders thereof for any purpose under the indentures, and no global security shall be exchangeable, except for a security registered in the name of the depositary. This means each person owning a beneficial interest in such global security must rely on the procedures of the depositary and, if such person is not a participant, on the procedures of the participant through which such person owns its interest, to exercise any rights of a holder under the indentures. USS understands that under existing industry practices, if USS requests any action of holders or an owner of a beneficial interest in such global security desires to give or take any action that a holder is entitled to give or take under the indentures, the depositary would authorize the participants holding the relevant beneficial interests to give or take such action, and such participants would authorize beneficial owners owning through such participant to give or take such action or would otherwise act upon the instructions of beneficial owners owning through them.

     Concerning the trustee

     The Bank of New York is also trustee for our 10 3/4% Senior Notes due August 1, 2008, our 9 ³/4% Senior Notes due May 15, 2010, a leveraged lease in which USS is the lessee and several series of obligations issued by various governmental authorities relating to environmental projects at various USS facilities. The Bank of New York is a lender under our revolving credit facility. USS and its subsidiaries also maintain ordinary banking relationships, including loans and deposit accounts, with The Bank of New York and anticipate that they will continue to do so.

DESCRIPTION OF CAPITAL STOCK

     The following is a description of the material terms of the capital stock of USS included in its certificate of incorporation, but it is not complete. This description is qualified by reference to the certificate of incorporation, and the Rights Agreement (the “Rights Agreement”) between USS and Mellon Investor Services LLC, as Rights Agent (the “Rights Agent”), that have been filed as exhibits to the registration statement of which this prospectus is a part. The terms of these securities may also be affected by the Delaware General Corporation law.

     General

     The authorized capital stock of USS consists of 40 million shares of preferred stock, without par value, and 400 million shares of common stock with a par value of $1.00 per share. As of February 26, 2007, there were no shares of preferred stock outstanding and 118,487,277 shares of common stock outstanding.

     Preferred Stock

     The preferred stock may be issued without the approval of the holders of common stock in one or more series, from time to time. The designation, powers, preferences and relative participating, optional or other special rights, and qualifications, limitations or restrictions of any preferred stock will be stated in a resolution providing for the issue of that series adopted by our board of directors and will be described in the appropriate prospectus supplement (if any), including the following:

	1.		When to issue the preferred stock, whether in one or more series so long as the total number of shares does not exceed 40 million;
	2.		The powers, preferences and relative participation, optional or other special rights, and qualifications, limits or restrictions on preferred stock;
	3.		The dividend rate of each series, the terms of payment, the priority of payment versus any other class of stock and whether the dividends will be cumulative;
	4.		Terms of redemption;
	5.		Any convertible features;
	6.		Any voting rights;
	7.		Liquidation preferences; and
	8.		Any other terms.

     Holders of preferred stock will be entitled to receive dividends (other than dividends of common stock) before any dividends are payable to holders of common stock.

     The future issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of USS.

     Common Stock

     The holders of common stock will be entitled to receive dividends when, as and if declared by the USS board of directors out of funds legally available therefor, subject to the rights of any shares of preferred stock at the time outstanding. The holders of common stock will be entitled to one vote for each share on all matters voted on generally by stockholders under our certificate of incorporation, including the election of directors. Holders of common stock do not have any cumulative voting, conversion, redemption or preemptive rights. In the event of dissolution, liquidation or winding up of USS, holders of the common stock will be entitled to share ratably in any assets remaining after the satisfaction in full of the prior rights of creditors, including holders of any then outstanding indebtedness, and subject to the aggregate liquidation preference and participation rights of any preferred stock then outstanding. The issuance of additional shares of authorized stock by USS may occur at such times and under such circumstances as to have a dilutive effect on earnings per share and on the equity ownership of the holders of common stock.

     Stock Transfer Agent and Registrar

     USS acts as its own transfer agent at the following address: United States Steel Corporation, Shareholders Services Department, 600 Grant Street, Room 611, Pittsburgh, PA 15219-2800. USS is also the registrar for its common stock and preferred stock.

     Wells Fargo Shareowner Services, 161 N. Concord Exchange, South St. Paul, MN 55075 serves as co-transfer agent.

     Rights Plan

     The following is a brief description of the terms of the stockholders rights plan set forth in the Rights Agreement between USS and Mellon Investor Services LLC, as Rights Agent.

     The purpose of the Rights Agreement is to:

	•		Give our board of directors the opportunity to negotiate with any persons seeking to obtain control of USS;
	•		Deter acquisitions of voting control of USS without assurance of fair and equal treatment of all USS stockholders; and
	•		Prevent a person from acquiring in the market a sufficient amount of voting power to be in a position to block an action sought to be taken by our stockholders.

     The exercise of the Rights would cause substantial dilution to a person attempting to acquire USS on terms not approved by our board of directors and would therefore significantly increase the price that person would have to pay to complete the acquisition. The Rights Agreement may deter a potential acquisition or tender offer.

     Under the Rights Agreement, the Right to purchase from USS one-hundredth of a share of Series A Junior Preferred Stock, no par value (the “Junior Preferred Stock”), at a purchase price of $110 in cash, subject to adjustment, is attached to each share of common stock.

     The Rights will expire at the close of business on December 31, 2011, unless that date is extended or the rights are earlier redeemed or exchanged by USS as described below.

     Until the Rights are distributed, they will:

	•		Not be exercisable;
	•		Be represented by the same certificates that represent the common stock; and
	•		Trade together with the common stock.

     If the Rights are distributed, they will become exercisable, and USS would issue separate certificates representing the Rights, which would trade separately from USS’ common stock.

     The Rights would be distributed upon the earlier of

	•		10 business days following a public announcement that a person or group of affiliated or associated persons (an “Acquiring Person”) has acquired (except pursuant to a Qualifying Offer (defined in the Rights Agreement as an all-cash tender offer for all outstanding shares of common stock meeting certain prescribed requirements)), or obtained the right to acquire, beneficial ownership of common stock representing 15% or more of the total voting power of all outstanding shares of common stock (the “Stock Acquisition Date”), or
	•		10 business days (or upon such later date as may be determined by the board of directors) following the commencement of a tender offer or exchange offer (other than a Qualifying Offer) that would result in a person or a group beneficially owning common stock representing 15% or more of the total voting power of all outstanding shares of common stock.

     However, an “Acquiring Person” will not include USS, any of its subsidiaries, any of its employee benefit plans or any person organized pursuant to those employee benefit plans or a person acquiring pursuant to a Qualifying Offer. The Rights Agreement also contains provisions designed to prevent the inadvertent triggering of the Rights by institutional or certain other stockholders.

     If a person or group becomes the beneficial owner of common stock representing 15% or more of the total voting power of all outstanding shares of common stock (except pursuant to a Qualifying Offer), the Rights “flip-in” and entitle each holder of a Right (other than the Acquiring Person and certain related parties) to receive, upon exercise, common stock (or in certain circumstances, cash, property, or other securities of USS), having a value equal to two times the exercise price of the Right. However, Rights are not exercisable until such time as the Rights are no longer redeemable by USS as set forth below.

     If at any time following the Stock Acquisition Date, (i) USS consolidates with, or merges with and into, any other person in a transaction in which USS is not the surviving corporation (other than a merger that follows a Qualifying Offer) or another person consolidates with, or merges with or into, USS and USS’ common stock is changed into or exchanged for securities of another person or cash or other property, or (ii) 50% or more of USS’ assets, earning power or cash flow is sold or transferred, the Rights “flip-over” and entitle each holder of a Right (other than an Acquiring Person and certain related parties) to receive, upon exercise, common stock of the acquiring company having a value equal to two times the exercise price of the Right.

     USS reserves the right, before the occurrence of an event described in the two preceding paragraphs, to require that upon an exercise of Rights, a number of Rights be exercised so that only whole shares of Junior Preferred Stock would be issued.

     At any time until the earlier of 10 business days following the Stock Acquisition Date and December 31, 2011 (subject to extension), USS may redeem the Rights in whole, but not in part, at a price of $.01 per whole Right payable in stock or cash or any other form of consideration deemed appropriate by its board of directors (the “Redemption Price”). Immediately upon the action of the Board of Directors ordering redemption of the Rights, the Rights will terminate and the holders of the Rights will have only the right to receive the Redemption Price.

     The board of directors may, at its option, at any time after any person becomes an Acquiring Person, exchange all or part of the outstanding and exercisable Rights (other than Rights held by the Acquiring Person and certain related parties) for shares of common stock at an exchange ratio of one share of common stock for each Right (subject to certain anti-dilution adjustments). However, the board of directors may not effect such an exchange at any time any person or group beneficially owns common stock representing 50% or more of the total voting power of the common stock then outstanding. Immediately after the board of directors orders such an exchange, the right to exercise the Rights will terminate, and the holders of the Rights will have only the right to receive shares of common stock at the exchange ratio.

     As long as the Rights are attached to shares of common stock, USS will issue Rights on each share of common stock issued prior to the earlier of the rights distribution date and the expiration date of the Rights so that all such shares will have attached Rights.

     A holder of Rights will not, as such, have any rights as a shareholder of USS, including rights to vote or receive dividends.

     The purchase price payable upon exercise of the Rights is subject to adjustment from time to time to prevent dilution, subject to the qualifications set forth in the rights agreement:

	•		In the event of a stock dividend on, or a subdivision, combination or reclassification of, the Junior Preferred Stock;
	•		If holders of Junior Preferred Stock are granted certain rights or warrants to subscribe for Junior Preferred Stock or securities convertible into Junior Preferred Stock at less than the market price of the Junior Preferred Stock; or
	•		Upon the distribution to holders of the Junior Preferred Stock of evidences of indebtedness or assets (excluding regular quarterly cash dividends) or of subscription rights or warrants (other than those referred to above).

     At any time prior to the distribution of the Rights, the board of directors may amend any provision of the Rights Agreement. After the distribution of the Rights, the board of directors may amend the provisions of the Rights Agreement in order to:

	•		Cure any ambiguity;
	•		Correct any defective or inconsistent provision;
	•		Shorten or lengthen any time period under the Rights Agreement, subject to the limitations specified in the rights agreement; or
	•		Make changes that will not adversely affect the interests of the holders of Rights (other than an Acquiring Person and certain related parties);

provided, that no amendment may be made when the Rights are not redeemable.

     The distribution of the Rights will not be taxable to USS or its stockholders. A stockholder may recognize taxable income in the event that the Rights become exercisable for common stock (or other consideration) of USS or common stock of an acquiring company.

     This description is only a summary of the material provisions of the rights agreement. We urge you to read the Rights Agreement because it, and not this description, defines your rights as holders of Rights. A copy of the Rights Agreement is available free of charge from the Rights Agent by writing to Mellon Investor Services, LLC at 500 Grant Street, Room 2122, Pittsburgh, Pennsylvania 15219 or from USS. (See “Where You Can Find More Information.”)

     Delaware Law, Our Certificate of Incorporation and By-Laws Contain Provisions That May Have an Anti-Takeover Effect

     Certain provisions of Delaware law and our certificate of incorporation could make more difficult or delay a change in control of USS by means of a tender offer, a proxy contest or otherwise and the removal of incumbent directors. These provisions are intended to discourage certain types of coercive takeover practices and inadequate takeover bids, even though such a transaction may offer our stockholders the opportunity to sell their stock at a price above the prevailing market price. Our board of directors believes that these provisions are appropriate to protect the interests of USS and of its stockholders.

     Delaware Law. We are governed by the provisions of Section 203 of the Delaware General Corporation Law. In general, Section 203 prohibits a public Delaware corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the time that the person became an interested stockholder, unless:

	•		Prior to the time that the person became an interested stockholder the corporation’s board of directors approved either the business combination or the transaction that resulted in the stockholder’s becoming an interested stockholder;
	•		Upon consummation of the transaction which resulted in the stockholder’s becoming an interested stockholder, the stockholder owned at least 85% of the outstanding voting stock of the corporation at the time the transaction commenced, excluding for the purpose of determining the number of shares outstanding those shares owned by the corporation’s officers and directors and by employee stock plans in which employee participants do not have the right to determine confidentially whether shares held subject to the plan will be tendered in a tender or exchange offer; or
	•		At or subsequent to the time, the business combination is approved by the corporation’s board of directors and authorized at an annual or special meeting of its stockholders, and not by written consent, by the affirmative vote of at least 66 2/3% of its outstanding voting stock that is not owned by the interested stockholder.

     A “business combination” includes mergers, asset sales or other transactions resulting in a financial benefit to the stockholder. An “interested stockholder” is a person who, together with affiliates and associates, owns (or within three years did own) 15% or more of the corporation’s voting stock.

     Certificate of Incorporation and By-Laws. Our certificate of incorporation provides that our board of directors is classified into three classes of directors, each class consisting of approximately one-third of the directors. Directors serve a three-year term, with a different class of directors up for election each year. Under Delaware law, directors of a corporation with a classified board may be removed only for cause unless the corporation’s certificate of incorporation provides otherwise. Our certificate of incorporation does not provide otherwise. Board classification could prevent a party who acquires control of a majority of USS’ outstanding voting stock from obtaining control of our board of directors until the second annual stockholders’ meeting following the date that party obtains that control.

     Our certificate of incorporation also provides that any action required or permitted to be taken by its stockholders must be effected at a duly called annual or special meeting and may not be taken by written consent.

     Our by-laws provide that special meetings of stockholders may be called only by the board of directors and not by the stockholders. Our by-laws include advance notice and informational requirements and time limitations on any director nomination or any new proposal that a stockholder wishes to make at a meeting of stockholders. In general, a stockholder’s notice of a director nomination or proposal will be timely if delivered or mailed to our Secretary at our principal executive offices not less than 45 days and not more than 75 days prior to the first anniversary of the date on which the proxy materials for the preceding year’s annual meeting were first mailed and, in certain situations, 90 days, before the annual meeting or within 10 days following the announcement of the date of the meeting. These provisions may preclude stockholders from bringing matters before a meeting or from making

nominations for directors at these meetings.

     Our certificate of incorporation and by-laws do not include a provision for cumulative voting for directors. Under cumulative voting, a minority stockholder holding a sufficient percentage of a class of shares may be able to ensure the election of one or more directors.

     Our certificate of incorporation provides for the issuance of preferred stock, at the discretion of our board of directors, from time to time, in one or more series, without further action by our stockholders, unless approval of our stockholders is deemed advisable by our board of directors or required by applicable law, regulation or stock exchange listing requirements. In addition, our authorized but unissued shares of our common stock will be available for issuance from time to time at the discretion of our board of directors without the approval of our stockholders, unless such approval is deemed advisable by our board of directors or required by applicable law, regulation or stock exchange listing requirements. One of the effects of the existence of authorized, unissued and unreserved shares of our common stock and preferred stock could be to enable our board of directors to issue shares to persons friendly to current management that could render more difficult or discourage an attempt to obtain control of USS by means of a merger, tender offer, proxy contest or otherwise, and thereby protect the continuity of our management. Such additional shares also could be used to dilute the stock ownership of persons seeking to obtain control of USS.

     Our certificate of incorporation provides that vacancies in our board of directors may be filled only by the affirmative vote of a majority of the remaining directors. The certificate of incorporation also provides that directors may be removed from office only with cause. These provisions preclude stockholders from removing directors without cause and filling vacancies with their own nominees.

     Our Rights will permit disinterested stockholders to acquire additional shares of USS, or of an acquiring company, at a substantial discount in the event of certain changes in control. See “Description of Capital Stock — Rights Plan.”

     Certain provisions described above may have the effect of delaying stockholder actions with respect to certain business combinations. As such, the provisions could have the effect of discouraging open market purchases of our shares of common stock because such provisions may be considered disadvantageous by a stockholder who desires to participate in a business combination.

     Limitations of Liability and Indemnification Matters

     Our certificate of incorporation provides that a director is not personally liable to us or our stockholders for monetary damages for any breach of fiduciary duty as a director, except (1) for breach of the director’s duty of loyalty to us and our stockholders, (2) for acts and omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (3) under Section 174 of the Delaware General Corporation Law or (4) for any transaction from which the director derived an improper personal benefit. These provisions of our certificate of incorporation are intended to afford directors protection, and limit their potential liability, to the fullest extent permitted by Delaware law. Because of these provisions, stockholders may be unable to recover monetary damages against directors for actions taken by them that constitute negligence or gross negligence or that are in violation of some of their fiduciary duties. These provisions do not affect a director’s responsibilities under any other laws, such as the federal securities laws.

     In addition, our By-Laws provide that we will indemnify our directors and officers to the fullest extent permitted by law.

     We have obtained directors’ and officers’ insurance for our directors and officers for specified liabilities.

DESCRIPTION OF DEPOSITARY SHARES

     The following briefly summarizes the material provisions of the deposit agreement and of the depositary shares and depositary receipts, other than pricing and related terms disclosed for a particular issuance in an accompanying prospectus supplement. You should read the particular terms of any depositary shares and any depositary receipts that we offer and any deposit agreement relating to a particular series of preferred stock that will be described in more detail in a prospectus supplement. The prospectus supplement will also state whether any of the generalized provisions summarized below do not apply to the depositary shares or depositary receipts being offered. A copy of the form of deposit agreement, including the form of depositary receipt, is incorporated by reference as an exhibit in the registration statement of which this prospectus forms a part. You can obtain copies of these documents by following the directions on page 1 under the caption “Where You Can Find More Information.” You should read the more detailed provisions of the deposit agreement and the form of depositary receipt for provisions that may be important to you.

     General

     USS may, at its option, elect to offer fractional shares of preferred stock, rather than full shares of preferred stock. In such event,

we will issue receipts for depositary shares, each of which will represent a fraction of a share of a particular series of preferred stock.

     The shares of any series of preferred stock represented by depositary shares will be deposited under a deposit agreement between USS and a bank or trust company selected by USS having its principal office in the United States and having a combined capital and surplus of at least $50 million, as preferred stock depositary. Each owner of a depositary share will be entitled to all the rights and preferences of the underlying preferred stock, including dividend, voting, redemption, conversion and liquidation rights, in proportion to the applicable fraction of a share of preferred stock represented by such depositary share.

     The depositary shares will be evidenced by depositary receipts issued pursuant to the deposit agreement. Depositary receipts will be distributed to those persons purchasing the fractional shares of preferred stock in accordance with the terms of the applicable prospectus supplement.

     Dividends and Other Distributions

     The preferred stock depositary will distribute all cash dividends or other cash distributions received in respect of the deposited preferred stock to the record holders of depositary shares relating to such preferred stock in proportion to the number of such depositary shares owned by such holders.

     The preferred stock depositary will distribute any property received by it other than cash to the record holders of depositary shares entitled thereto. If the preferred stock depositary determines that it is not feasible to make such distribution, it may, with the approval of USS, sell such property and distribute the net proceeds from such sale to such holders.

     Redemption of Preferred Stock

     If a series of preferred stock represented by depositary shares is to be redeemed, the depositary shares will be redeemed from the proceeds received by the preferred stock depositary resulting from the redemption, in whole or in part, of such series of preferred stock. The depositary shares will be redeemed by the preferred stock depositary at a price per depositary share equal to the applicable fraction of the redemption price per share payable in respect of the shares of preferred stock so redeemed.

     Whenever USS redeems shares of preferred stock held by the preferred stock depositary, the preferred stock depositary will redeem as of the same date the number of depositary shares representing shares of preferred stock so redeemed. If fewer than all the depositary shares are to be redeemed, the depositary shares to be redeemed will be selected by the preferred stock depositary by lot or ratably as the preferred stock depositary may decide.

     Voting Deposited Preferred Stock

     Upon receipt of notice of any meeting at which the holders of any series of deposited preferred stock are entitled to vote, the preferred stock depositary will mail the information contained in such notice of meeting to the record holders of the depositary shares relating to such series of preferred stock. Each record holder of such depositary shares on the record date will be entitled to instruct the preferred stock depositary to vote the amount of the preferred stock represented by such holder’s depositary shares. The preferred stock depositary will try to vote the amount of such series of preferred stock represented by such depositary shares in accordance with such instructions.

     USS will agree to take all actions that the preferred stock depositary determines are necessary to enable the preferred stock depositary to vote as instructed. The preferred stock depositary will abstain from voting shares of any series of preferred stock held by it for which it does not receive specific instructions from the holders of depositary shares representing such shares.

     Amendment and Termination of the Deposit Agreement

     The form of depositary receipt evidencing the depositary shares and any provision of the deposit agreement may at any time be amended by agreement between USS and the preferred stock depositary. However, any amendment that materially and adversely alters any existing right of the holders of depositary shares (other than certain changes in the fees of the preferred stock depositary) will not be effective unless such amendment has been approved by the holders of at least a majority of the depositary shares then outstanding. Every holder of an outstanding depositary receipt at the time any such amendment becomes effective shall be deemed, by continuing to hold such depositary receipt, to consent and agree to such amendment and to be bound by the deposit agreement, as amended thereby. The deposit agreement may be terminated only if:

•

All outstanding depositary shares have been redeemed; or

•

A final distribution in respect of the preferred stock has been made to the holders of depositary shares in connection with any liquidation, dissolution or winding up of USS.

     Charges of Preferred Stock Depositary, Taxes and Other Government Charges

     USS will pay all transfer and other taxes and governmental charges arising solely from the existence of the depositary arrangements. USS also will pay charges of the depositary in connection with the initial deposit of preferred stock and any redemption of preferred stock. Holders of depositary receipts will pay other transfer and other taxes and governmental charges and such other charges, including a fee for the withdrawal of shares of preferred stock upon surrender of depositary receipts, as are expressly provided in the deposit agreement to be for their accounts.

     Appointment, Resignation and Removal of Depositary

     USS will appoint the preferred stock depository. The preferred stock depositary may resign at any time by delivering to USS notice of its intent to do so and USS may at any time remove the preferred stock depositary, any such resignation or removal to take effect upon the appointment of a successor preferred stock depositary and its acceptance of such appointment. Such successor preferred stock depositary must be appointed within 60 days after delivery of the notice of resignation or removal and must be a bank or trust company having its principal office in the United States and having a combined capital and surplus of at least $50 million.

     Miscellaneous

     USS will transmit to the record holders of depositary shares all notices and reports that USS is required to furnish to the holders of the depositary shares.

     Neither the preferred stock depositary nor USS will be liable under the deposit agreement other than for its negligence or willful misconduct. The preferred stock depositary and USS will not be obligated to prosecute or defend any legal proceeding in respect of any depositary shares, depositary receipts or shares of preferred stock unless satisfactory indemnity is furnished. USS and the preferred stock depositary may rely upon written advice of counsel or accountants, or upon information provided by holders of depositary receipts or other persons believed to be competent and on documents believed to be genuine. The preferred stock depositary will not be responsible for any failure to carry out any instruction to vote any shares of preferred stock, as long as that action or non-action is in good faith.

DESCRIPTION OF WARRANTS

     USS may issue Warrants for the purchase of Debt Securities, preferred stock or common stock (each a “USS Security,” and together the “USS Securities”). Warrants may be issued independently or together with any USS Security offered by any prospectus supplement and may be attached to or separate from any such USS Security. Each series of Warrants will be issued under a separate warrant agreement (a “Warrant Agreement”) to be entered into between USS and a bank or trust company, as warrant agent (the “Warrant Agent”). The Warrant Agent will act solely as an agent of USS in connection with the Warrants and will not assume any obligation or relationship of agency or trust for or with any holders or beneficial owners of Warrants. The following summary of certain provisions of the Warrants does not purport to be complete and is subject to, and qualified in its entirety by reference to, the provisions of the Warrant Agreement that will be filed with the SEC in connection with the offering of such Warrants.

     Debt Warrants

     If any Debt Security, Preferred Stock, depositary shares representing fractional shares of preferred stock or Warrant is converted or exchanged into any other security the conversion or exchange terms thereof will be set forth in the Prospectus Supplement issued for the sale of such convertible or exchangeable security. These terms will include some or all of the terms described for Warrants.

DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

     USS may issue stock purchase contracts, including contracts obligating holders to purchase from us, and us to sell to holders, a specified number of shares of common stock at a future date or dates. The consideration per share of common stock may be fixed at the time the stock purchase contracts are issued or may be determined by reference to a specific formula described in the stock purchase contracts. USS may issue the stock purchase contracts separately or as a part of stock purchase units consisting of a stock purchase contract and one or more shares of our preferred stock or debt securities or debt obligations of third parties (including U.S. Treasury securities) securing the holders’ obligations to purchase the shares of common stock under the stock purchase contracts. The stock purchase contracts may require us to make periodic payments to the holders of stock purchase units or vice-versa. These payments may be unsecured or pre-funded on some basis. The stock purchase contracts may require holders to secure their obligations in a specified manner. The applicable prospectus supplement will describe the specific terms of any stock purchase contracts or stock purchase units.

PLAN OF DISTRIBUTION

     We may offer the offered securities in one or more of the following ways from time to time:

	•		To or through underwriting syndicates represented by managing underwriters;
	•		Through one or more underwriters without a syndicate for them to offer and sell to the public;
	•		Through dealers or agents;
	•		To investors directly in negotiated sales or in competitively bid transactions; or
	•		To holders of other securities in exchanges in connection with acquisitions.

     The prospectus supplement for each series of securities we sell will describe the offering, including:

	•		The name or names of any underwriters;
	•		The purchase price and the proceeds to us from that sale;
	•		Any underwriting discounts and other items constituting underwriters’ compensation;

	•		Any commissions paid to agents;
	•		The initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers; and
	•		Any securities exchanges on which the securities may be listed.

     Underwriters

     If underwriters are used in a sale, we will execute an underwriting agreement with them regarding those securities. Unless otherwise described in the prospectus supplement, the obligations of the underwriters to purchase these securities will be subject to conditions, and the underwriters must purchase all of these securities if any are purchased.

     The securities subject to the underwriting agreement may be acquired by the underwriters for their own account and may be resold by them from time to time in one or more transactions, including negotiated transactions, at a fixed offering price or at varying prices determined at the time of sale. Underwriters may be deemed to have received compensation from us in the form of underwriting discounts or commissions and may also receive commissions from the purchasers of these securities for whom they may act as agent. Underwriters may sell these securities to or through dealers. These dealers may receive compensation in the form of discounts, concessions or commissions from the underwriters and/or commissions from the purchasers for whom they may act as agent. Any initial offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.

     We may authorize underwriters to solicit offers by institutions to purchase the securities subject to the underwriting agreement from us, at the public offering price stated in the prospectus supplement under delayed delivery contracts providing for payment and delivery on a specified date in the future. If we sell securities under these delayed delivery contracts, the prospectus supplement will state that this is the case and will describe the conditions to which these delayed delivery contracts will be subject and the commissions payable for that solicitation.

     In connection with underwritten offerings of the securities, the underwriters may engage in over-allotment, stabilizing transactions, covering transactions and penalty bids in accordance with Regulation M under the Securities Exchange Act of 1934, as follows:

	•		Over-allotment involves sales in excess of the offering size, which creates a short position for the underwriters.
	•		Stabilizing transactions permit bids to purchase the underlying security so long as the stabilizing bids do not exceed a specified maximum.
	•		Covering transactions involve purchases of the securities in the open market after the distribution has been completed in order to cover short positions.
	•		Penalty bids permit the underwriters to reclaim a selling concession from a broker/dealer when the securities originally sold by that broker/dealer are repurchased in a covering transaction to cover short positions.

     These stabilizing transactions, covering transactions and penalty bids may cause the price of the securities to be higher than it would otherwise be in the absence of these transactions. If these transactions occur, they may be discontinued at any time.

     Agents

     We may also sell any of the securities through agents designated by us from time to time. We will name any agent involved in the offer or sale of these securities and will list commissions payable by us to these agents in the prospectus supplement. These agents will be acting on a best efforts basis to solicit purchases for the period of its appointment, unless we state otherwise in the prospectus supplement.

     Direct Sales

     We may sell any of the securities directly to purchasers. In this case, we will not engage underwriters or agents in the offer and sale of these securities.

     In addition, debt securities or shares of common stock or preferred stock may be issued upon the exercise of warrants.

     Indemnification

     We may indemnify underwriters, dealers or agents who participate in the distribution of securities against certain liabilities, including liabilities under the Securities Act of 1933, and may agree to contribute to payments that these underwriters, dealers or agents may be required to make.

     No Assurance of Liquidity

     The securities we offer may be a new issue of securities with no established trading market. Any underwriters that purchase securities from us may make a market in these securities. The underwriters will not be obligated, however, to make a market and may discontinue market-making at any time without notice to holders of the securities. We cannot assure you that there will be liquidity in the trading market for any securities of any series.

LEGAL MATTERS

     Unless otherwise specified in the prospectus supplement accompanying this prospectus, the validity of the issuance of the offered securities will be passed upon for USS by R.M. Stanton, Esq., Assistant General Counsel — Corporate and Assistant Secretary of USS. Mr. Stanton, in his capacity as set forth above, is paid a salary by USS, participates in various employee benefit plans offered by USS and owns, and has options to purchase, common stock of USS. Any underwriters will also be advised about the validity of the securities and other legal matters by their own counsel, which will be named in the prospectus supplement.

EXPERTS

     The consolidated financial statements, financial statement schedule and management’s assessment of the effectiveness of internal control over financial reporting (which is included in Management’s Reports to Stockholders) incorporated in this prospectus by reference to the Annual Report on Form 10-K for the year ended December 31, 2006 have been so incorporated in reliance on the report of PricewaterhouseCoopers LLP, an independent registered public accounting firm, given on the authority of said firm as experts in auditing and accounting.

     Item 15. Indemnification of Directors and Officers.

     Article V of the Registrant’s By-Laws provides that the Company shall indemnify to the fullest extent permitted by law any person who is made or is threatened to be made a party or is involved in any action, suit, or proceeding whether civil, criminal, administrative or investigative by reason of the fact that he is or was a director, officer, employee or agent of the Registrant or is or was serving at the request of the Corporation as an officer, director, employee or agent of another corporation, partnership, joint venture, trust, enterprise, or nonprofit entity.

     The Registrant is empowered by Section 145 of the Delaware General Corporation Law, subject to the procedures and limitations stated therein, to indemnify any person who was or is a party or is threatened to be made a party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Registrant) by reason of the fact that such person is or was an officer, employee, agent or director of the Registrant, or is or was serving at the request of the Registrant as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if he acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the Registrant, and, with respect to any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful. The Registrant may indemnify any such person against expenses (including attorneys’ fees) in an action by or in the right of the Registrant under the same conditions, except that no indemnification is permitted without judicial approval if such person is adjudged to be liable to the Registrant. To the extent a director or officer is successful on the merits or otherwise in the defense of any action referred to above, the Registrant must indemnify him against the expenses that he actually and reasonably incurred in connection therewith.

     Policies of insurance are maintained by the Registrant under which directors and officers of the Registrant are insured, within the limits and subject to the limitations of the policies, against certain expenses in connection with the defense of actions, suits or proceedings, and certain liabilities which might be imposed as a result of such actions, suits or proceedings, to which they are parties by reason of being or having been such directors or officers.

     The Registrant’s Certificate of Incorporation provides that no director shall be personally liable to the Registrant or its stockholders for monetary damages for any breach of fiduciary duty by such director as a director, except (i) for breach of the director’s duty of loyalty to the Registrant or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) pursuant to Section 174 of the Delaware General Corporation Law, or (iv) for any transaction from which the director derived an improper personal benefit.

     Item 16. List of Exhibits.

     See Exhibit Index.

     Item 17. Undertakings.

The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table on the cover of this registration statement;

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

provided, however, that paragraphs (1)(i), (1)(ii) and (1)(iii) do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in reports filed with or furnished to the Commission by the registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in the registration statement or is contained in a form of prospectus filed pursuant to Rule 424(b) that is part of the registration statement.

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

(3) To remove from registration, by means of a post-effective amendment, any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining any liability under the Securities Act of 1933 to any purchaser:

(i) Each prospectus filed by the Registrant pursuant to Rule 424(b)(3) shall be deemed to be part of the registration statement as of the date the filed prospectus was deemed part of and included in the registration statement; and

(ii) Each prospectus required to be filed pursuant to Rule 424(b)(2), (b)(5) or (b)(7) as a part of a registration statement in reliance on Rule 430B relating to an offering made pursuant to Rule 415(a)(1)(i), (vii) or (x) for the purpose of providing the information required by Section 10(a) of the Securities Act of 1933 shall be deemed to be part of and included in the registration statement as of the earlier of the date such form of prospectus is first used after effectiveness or the date of the first contract of sale of securities in the offering described in the prospectus. As provided in Rule 430B, for liability purposes of the issuer and any person that is at that date an underwriter, such date shall be deemed to be a new effective date of the registration statement relating to the securities in the registration statement to which the prospectus related, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof. Provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registrations statement or prospectus that is part of the registrations statement will, as to a purchaser with a time of contract of sale prior to such effective date, supersede or modify any statement that was made in the registration statement or made in any such document immediately prior to such effective date.

(5) That, for purposes of determining liability of the Registrant under the Securities Act of 1933 to any purchaser in the

initial distribution of the securities, the undersigned Registrant undertakes that in a primary offering of securities of the undersigned Registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned Registrant will be a seller to the purchaser and will be considered to offer to sell such securities to the purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned Registrant relating to the offering required to be filed pursuant to Rule 424;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned Registrant or used or referred to by the undersigned Registrant;

(iii) The portion of any other free writing prospectus relating to the offering containing material information about the undersigned Registrant or its securities provided by or on behalf of the undersigned Registrant; and

(iv) Any other communication that is an offer in the offering made by the undersigned Registrant to the purchaser.

(6) That, for purposes of determining any liability under the Securities Act of 1933, each filing of Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(7) To file an application for the purpose of determining the eligibility of the trustee to act under subsection (a) of Section 310 of the Trust Indenture Act in accordance with the rules and regulations prescribed by the Commission under Section 305(b) of the Trust Indenture Act.

(8) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of USS pursuant to the provisions described under Item 15 above, or otherwise, USS has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act of 1933 and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by USS of expenses incurred or paid by a director, officer or controlling person of USS in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, USS will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification is against public policy as expressed in the Securities Act of 1933 and will be governed by the final adjudication of such issue.
