existing and future secured indebtedness to the extent of the assets securing such indebtedness, and wil

be structural y subordinated to any indebtedness and other liabilities of our subsidiaries.

Other debt outstanding
As of December 31, 2012, we had an aggregate of approximately $3,818 mil ion of senior indebtedness
outstanding (consisting of approximately $3,163 mil ion of senior notes, $549 mil ion of obligations relating
to environmental revenue bonds, $70 mil ion relating to recovery zone facility bonds, and $36 mil ion of
obligations under capital leases and other debt).

At December 31, 2012, our subsidiaries had an aggregate amount of outstanding indebtedness of

approximately $151 mil ion (consisting of C$150 mil ion (approximately $151 mil ion using exchange rates as
of December 31, 2012) outstanding under a note (the "Province Note") to the Province of Ontario.

U. S. Steel has a $625 mil ion Receivables Purchase Agreement with financial institutions that expires in

July 2014. As of December 31, 2012, U. S. Steel had no outstanding borrowings under this facility and
more than $625 million of eligible receivables.

U. S. Steel has an $875 mil ion Credit Agreement (the "Credit Facility") with a consortium of lenders that
includes a security interest in the majority of our domestic inventory, certain accounts receivable and
related col ateral and which wil expire July 2016. As of December 31, 2012, there were no amounts drawn

under the Credit Facility and inventory levels supported the ful $875 mil ion of availability. Under the Credit
Facility, if availability is less than $87.5 mil ion, U. S. Steel must comply with a fixed charge coverage ratio.
Since availability was greater than $87.5 mil ion as of December 31, 2012, compliance with the fixed
charge coverage ratio covenant was not applicable.

(approximately $26 mil ion), and the availability was approximately $24 mil ion due to approximately $2
mil ion of customs and other guarantees outstanding. The 20 mil ion facility expires in December 2015.

The indenture governing the notes does not limit the amount of debt that we or our subsidiaries may incur.

Table of Contents
Covenants
We wil issue the notes under a senior indenture with The Bank of New York Mel on Trust Company N.A.,
as trustee. The senior indenture wil , among other things, restrict our ability and the ability of certain of our
subsidiaries to:

· create liens on any Principal Property or shares of stock or other equity interests of a Subsidiary that

owns any Principal Property to secure indebtedness;

· engage in sale leaseback transactions with respect to any Principal Property; and

· consolidate, merge or transfer all or substantial y all of U. S. Steel's assets.

These covenants are subject to important exceptions and qualifications that are described in "Description of

the notes--Covenants."

Additional notes
The senior indenture governing the notes wil provide for unlimited issuances of additional notes. See
"Description of the notes--Additional issuances."

Book-entry form only
The notes wil be issued in book-entry form and wil be represented by one or more permanent global
certificates deposited with, or on behalf of, DTC and registered in the name of a nominee of DTC.

Table of Contents
Risk factors
Before investing in the notes, you should carefully consider the risks set forth in Item 1A of our annual report on Form 10-K for the year ended
December 31, 2012, as well as the following risks. These risks are not the only ones facing us. Additional risks not presently known to us or that we
currently deem immaterial may also impair our business operations or the value of the notes.
Risks related to an investment in the notes
The notes do not impose any limitations on our ability to incur additional debt or other obligations.
The senior indenture governing the notes does not restrict the future incurrence of secured indebtedness, unsecured indebtedness, guarantees or other
obligations. Except for the limitations in granting liens or entering into sales and leaseback of certain assets we currently own within the definition of
"Principal Property", the senior indenture does not restrict our ability to grant liens on our assets or to engage in sales and leaseback transactions. See
"Description of the notes--Limitations on liens and limitations on sales and leasebacks."
The notes will be effectively junior to the Credit Facility and any other secured indebtedness that we may issue in the future.
The notes are unsecured. Holders of our secured debt may foreclose on the assets securing such debt, reducing the cash flow from the foreclosed
property available for payment of unsecured debt, including the notes. We have granted the lenders under our $875 mil ion revolving Credit Facility a
first lien on the majority of our domestic inventories and certain accounts receivable. Holders of our secured debt also would have priority over
unsecured creditors in the event of our bankruptcy, liquidation or similar proceeding to the extent of the value of the col ateral securing such
indebtedness. As a result, the notes wil be effectively junior to the Credit Facility, secured obligations under capital leases and any secured debt that
we may issue in the future to the extent of the value of the col ateral securing such indebtedness.
The notes are obligations exclusively of U. S. Steel and not of our subsidiaries, and payment to holders of the notes will be structurally
subordinated to the claims of our subsidiaries' creditors.
The notes are not guaranteed by any of our subsidiaries. As a result, indebtedness or guarantees of indebtedness and other liabilities of each of our
subsidiaries, wil effectively rank senior to the indebtedness represented by the notes, to the extent of such subsidiary's assets. As of December 31,
2012, our subsidiaries had an aggregate of approximately $151 mil ion of indebtedness outstanding, consisting of C$150 mil ion due to the Province of
Ontario. In addition, the indenture governing the notes does not restrict the future incurrence of liabilities or issuances of preferred stock, including
unsecured indebtedness or guarantees of indebtedness, by our subsidiaries.
The notes do not contain restrictive financial covenants and we may incur substantially more debt or take other actions which may affect
our ability to satisfy our obligations under the notes.
Other than as described under "Description of notes--Covenants--Limitation on liens" and "--Limitation on sale and leaseback transactions," the
indenture governing the notes does not contain any financial or operating covenants or restrictions on the incurrence of indebtedness

(including secured debt), the payments of dividends or the issuance or repurchase of securities by us or any of our subsidiaries. In addition, the limited
covenants applicable to the 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 and take a number of other actions that are not limited by the terms of the notes could have the effect of
diminishing our ability to make payments on the notes when due, and require us to dedicate a substantial portion of our cash flow from operations to
payments on our indebtedness, which would reduce the availability of cash flow to fund our operations, working capital and capital expenditures.
The definition of a "Change of Control" requiring us to repurchase the notes is limited, and the market price of the notes may decline if we
enter into a transaction that is not a Change of Control under the senior indenture governing the notes.
The term "Change of Control" (as defined in the senior indenture) is limited in its scope and does not include many events that might cause the market
price of the notes to decline. Furthermore, we are required to repurchase notes of each series upon a Change of Control only if, as a result of such
Change of Control, the notes receive certain reductions in ratings, and the Rating Agencies (as defined in the senior indenture) assigning the ratings
expressly link the reductions in ratings to the Change of Control. As a result, our obligation to repurchase the notes upon the occurrence of a Change of
Control is limited and may not preserve the value of the notes in the event of a highly leveraged transaction, reorganization, merger or similar
transaction.
Although our other senior notes general y have the same change of control protection as the notes, others, such as the lenders under our Credit Facility
and the United Steelworkers, have broader change of control protection, and the senior indenture governing the notes does not restrict our ability to
agree to change of control provisions or to enter into transactions that would constitute a change of control under the notes or in any other agreement
into which we may enter.
If we experience a Change of Control, we may not have sufficient funds or be permitted under the terms of our debt instruments to repurchase the
notes. See "Description of the notes--Change of control offer."
There is no public market for the notes, which could limit their market price or your ability to sell them.
The notes are a new issue of securities for which there currently is no trading market. As a result, a market may not develop for any series of notes
and you may not be able to sel your notes. Any notes that are traded after their initial issuance may trade at a discount from their initial offering price.
Future trading prices of the notes wil depend on many factors, including prevailing interest rates, the market for similar securities, general economic
conditions and our financial condition, performance and prospects. Accordingly, you may be required to bear the financial risk of an investment in the
notes for an indefinite period of time. We do not intend to apply for listing or quotation of the notes on any securities exchange or automated quotation
system. While the underwriters may make a market in the notes they are not required to do so and consequently any market making with respect to the
notes may be discontinued at any time without notice. Even if the underwriters make a market in the notes the liquidity of such a market may be limited.
See "Underwriting."
