OFFERING MEMORANDUM

US$200,000,000

6.50% Senior Unsecured Guaranteed Notes due 2020

Unconditionally and irrevocably guaranteed by

Companhia Siderúrgica Nacional
____________
We are offering pursuant to this offering US$200,000,000 aggregate principal amount of CSN Resources S.A.'s 6.50% Senior
Unsecured Guaranteed Notes due 2020, or the New Notes. The New Notes are being offered as additional debt securities under
an indenture pursuant to which, on July 21, 2010, the Issuer (as defined below) issued US$1.0 billion of its 6.50% senior
unsecured guaranteed notes due 2020, or the Initial Notes. The New Notes constitute "additional notes" under the indenture.
The New Notes will have identical terms and conditions as the Initial Notes, other than their issue price and issue date, and will
constitute part of the same series as, and vote together as a single class with, the Initial Notes, except that the New Notes
offered and sold in offshore transactions under Regulation S shall be issued and maintained under temporary ISIN and CUSIP
numbers during a 40-day distribution compliance period. See "Luxembourg Listing Information." References to the "Notes"
refer to the Initial Notes and the New Notes collectively, unless the context otherwise requires.
CSN Resources S.A., or the Issuer, is a public limited liability company (société anonyme) incorporated under the laws of the
Grand Duchy of Luxembourg, or Luxembourg. The Notes are unconditionally and irrevocably guaranteed by Companhia
Siderúrgica Nacional, referred to as the Company, CSN or the Guarantor, a corporation (sociedade anônima) incorporated under
the laws of the Federative Republic of Brazil, or Brazil. The Issuer is an indirect subsidiary of the Guarantor.
The Issuer will pay interest on the Notes semiannually in arrears on January 21 and July 21 of each year, starting July 21, 2012. The
Notes will mature on July 21, 2020. The Notes will be subject to redemption prior to maturity upon the imposition of certain changes
affecting taxation in Luxembourg or Brazil. The Notes will also be subject to redemption by the Issuer at any time at their principal
amount plus a "make-whole" premium and accrued and unpaid interest and additional amounts, if any, to the date of redemption. See
"Description of the Notes--Optional Redemption." Payments on the Notes will be payable in U.S. dollars and will be paid without
deduction for or on account of taxes imposed or levied by Luxembourg or Brazil to the extent set forth under "Description of the
Notes--Additional Amounts."
The Notes rank pari passu with all unsecured and unsubordinated obligations of the Issuer. The guarantee of the Notes, or the
Guaranty, ranks pari passu with all unsecured and unsubordinated obligations of CSN.
An application has been made for the New Notes to be admitted to listing on the Official List of the Luxembourg Stock
Exchange and to trading on the Euro MTF market.
Investing in the Notes involves risks. See "Risk Factors" beginning on page 14.
New Notes Price: 106.00%
plus accrued interest from January 21, 2012.
Purchasers will be required to pay accrued interest totaling US$433,333.33, or US$2.17 per US$1,000 principal amount of
New Notes from January 21, 2012 to February 3, 2012, the date we expect to deliver the New Notes.
Delivery of the New Notes was made in book-entry form only through The Depository Trust Company, or DTC, on or about
February 3, 2012.
The New Notes and the Guaranty have not been and will not be registered under the Securities Act. The New Notes may not
be offered or sold within the United States or to U.S. persons, except to qualified institutional buyers in reliance on the
exemption from registration provided by Rule 144A and to certain persons in offshore transactions in reliance on Regulation S.

Investors."

ENFORCEMENT OF CIVIL LIABILITIES
The Issuer is a public limited liability company (société anonyme) incorporated under the laws of Luxembourg
and CSN is duly incorporated as a corporation (sociedade anônima) under the laws of Brazil. Many of the Issuer's
and CSN's directors and officers, as well as certain of the experts named herein, reside in Brazil. All or a substantial
portion of the assets of CSN and of such directors and officers and such experts are located in Brazil. In the
Indenture (as defined under "Description of the Notes" below), each of the Issuer and CSN, as the case may be:

agrees to submit to the jurisdiction of the courts of the State of New York and the federal courts of the United States,
in each case sitting in the Borough of Manhattan, The City of New York, in connection with any suit, action or
proceedings, or to settle any disputes, which arise out of or in connection with the Notes, the Indenture or the
Guaranty and, for such purposes, agrees to submit to the jurisdiction of such courts; and

has agreed to appoint an agent for service of process in the Borough of Manhattan, The City of New York.
Except to the extent indicated in the immediately preceding sentence, none of the Issuer, CSN or any of their
respective directors or officers or such experts has consented to the jurisdiction of the courts of the United States or
any State thereof in connection with any suit brought by an investor in the Notes or the Guaranty or named an agent
for service of process within the United States or in any State thereof.
As a result, it may not be possible for investors to effect service of process within the United States upon the
Issuer, CSN or such persons or to enforce, in U.S. courts or the courts of other jurisdictions outside of Brazil,
judgments against the Issuer, CSN or such persons or judgments obtained in such courts predicated upon the civil
liability provisions of the federal securities laws of the United States or other applicable laws.
CSN has been advised by its internal legal counsel that judgments of United States courts for civil liabilities,
including those predicated upon the federal securities laws of the United States, may be enforced in Brazil, subject
to certain requirements described below. A judgment against CSN or its directors and officers obtained outside
Brazil would be enforceable in Brazil against such entity or person, without reconsideration of the merits, upon
confirmation ("homologacão") of the judgment by the Brazilian Superior Court of Justice if the foreign judgment:

is for the payment of a sum certain;

fulfills all formalities required for its enforceability under the laws of the country where the foreign
judgment is granted;

is issued by a competent court after proper service of process made in accordance with the laws of the country
where the foreign judgment is granted or the default ("revelia") of the defendant is legally verified;

is final and not subject to appeal;

is authenticated by a Brazilian consular office in the country where the foreign judgment is issued and is
accompanied by a sworn translation into Portuguese; and

is not contrary to Brazilian national sovereignty, public policy or good morals.
CSN has been further advised by internal legal counsel that, to the extent not deemed contrary to Brazilian national
sovereignty, public policy or good morals, original actions predicated on the federal securities laws of the United States
may be brought in Brazilian courts and that Brazilian courts will enforce liabilities in such actions against CSN and its
directors and officers. Internal legal counsel has further advised CSN that a person seeking to enforce such a judgment in
Brazilian courts (whether Brazilian or non-Brazilian) who resides outside Brazil during the course of litigation in Brazil
must post a bond to guarantee legal fees and court expenses if such person owns no real property in Brazil that may assure
such payment, except in the case of the enforcement of foreign judgments which have been duly confirmed by the
Brazilian Superior Court of Justice and in the case of claims for collection on a título executivo extrajudicial (an
instrument which may be enforced in Brazilian courts without a review on the merits). This bond must have a value
sufficient to satisfy the payment of court fees and defendant's attorney's fees, as determined by the Brazilian court.
Notwithstanding the foregoing, no assurance can be given that the confirmation process described above will be conducted
in a timely manner or that a Brazilian court would enforce a monetary judgment for violation of the federal securities laws
of the United States with respect to the Notes or the Guaranty. We have been advised that, if the Notes or the Indenture
iv

were to be declared void by a court applying the laws of the State of New York, a judgment obtained outside of
Brazil seeking to enforce the Guarantee may not be ratified by the Superior Court of Justice in Brazil.
Service of Process and Enforcement of Civil Liabilities in Luxembourg
The Issuer is a public limited liability company (société anonyme) under the laws of Luxembourg. Certain of
the Issuer's directors and executive officers are non-residents of the United States. In addition, all or a substantial
portion of the assets of the Issuer and substantially all of the assets of its directors are located outside the United
States. As a result, it may not be possible for you to serve process on these persons or the Issuer in the United States
or to enforce judgments obtained in U.S. courts against them or the Issuer based on civil liability provisions of the
securities laws of the United States.
We have been advised by our Luxembourg counsel that the United States and Luxembourg are not currently
bound by a treaty providing for reciprocal recognition and enforcement of judgments, other than arbitral awards
rendered in civil and commercial matters. According to such counsel, an enforceable judgment for the payment of
monies rendered by any U.S. Federal or state court based on civil liability, whether or not predicated solely upon the
U.S. securities laws, would not directly be enforceable in Luxembourg. However, a party who received such
favorable judgment in a U.S. court may initiate enforcement proceedings in Luxembourg (exequatur) by requesting
enforcement of the U.S. judgment by the District Court (Tribunal d'Arrondissement) pursuant to Section 678 of the
New Luxembourg Code of Civil Procedure. The District Court will authorize the enforcement in Luxembourg of the
U.S. judgment if it is satisfied that all of the following conditions are met:

the U.S. judgment is enforceable (exécutoire) in the United States;

the U.S. court awarding the judgment has jurisdiction to adjudicate the respective matter under applicable
U.S. Federal or state jurisdictions rules, and that jurisdiction is recognized by Luxembourg private
international and local law;

the U.S. court has applied to the dispute the substantive law which would have been applied by
Luxembourg courts;

the principles of natural justice have been complied with;

the U.S. judgment does not contravene international public policy or order as understood under the laws of
Luxembourg or has been given in proceedings of a criminal nature;

the U.S. court has acted in accordance with its own procedural laws; and

the judgment was granted following proceedings where the counterparty had the opportunity to appear, and
if it appeared, to present a defense.
In practice, Luxembourg courts now tend not to review the merits of a foreign judgment, although there is no
clear statutory prohibition of such review.

Our forward-looking statements are not guarantees of future performance, and our actual results or other
developments may differ materially from the expectations expressed in the forward-looking statements. As for
forward-looking statements that relate to future financial results and other projections, actual results will be different
due to the inherent uncertainty of estimates, forecasts and projections. Because of these uncertainties, potential

undertake any obligation to update them in light of new information or future developments or to release publicly
any revisions to these statements in order to reflect later events or circumstances or to reflect the occurrence of

PRESENTATION OF FINANCIAL INFORMATION
Our consolidated financial statements as of December 31, 2011 and 2010 and for the years then ended, included
in Form 20-F annexed herein, as well as the other financial information related to these financial statements included
in this offering memorandum, have been presented in reais and prepared in accordance with IFRS as issued by
IASB.
In this offering memorandum, references to "U.S. dollars" and "US$" are to the currency of the United States of
America and references to "reais" and "R$" are to the currency of Brazil. References in this offering memorandum
to "billions" are to thousands of millions, to "mt" denotes metric tons and to "mtpy" to metric tons per year.
For the convenience of the reader, certain financial information relating to us is presented in U.S. dollars in this
offering memorandum. Such information has been converted into U.S. dollars using the period end real/U.S. dollar
exchange rates published by the Brazilian Central Bank (Banco Central do Brasil), or the Central Bank, on
December 31, 2011, which was US$1.00 = R$1.8758. Investment amounts contained in this offering memorandum
have been translated at the commercial market exchange rate in effect on the date the investment was made. For a
discussion of historical Brazilian currency and U.S. dollar exchange rates, see "Exchange Rates." This translation
should not be construed as a representation that any such amounts have been, would have been or could be
converted at these or any other exchange rates.
Certain figures included in this offering memorandum have been subject to rounding adjustments; accordingly,
figures shown as totals in certain tables may not be an arithmetic aggregation of the figures which precede them.
Changes in Regulatory Requirements for Presentation of Financial Statements Convergence to IFRS
Starting with the year ended December 31, 2010, Brazilian listed companies are required to publish their
consolidated financial statements in accordance with IFRS. Those consolidated financial statements must be
prepared based on IFRS as issued by the IASB.
Consequently, the financial statements and other financial information for the years ended December 31, 2011
and 2010 included in Form 20-F, unless otherwise indicated, were prepared and presented in accordance with IFRS
as issued by IASB.
Previously published consolidated financial statements in our annual report on Form 20-F for our financial year
ended December 31, 2009, as well as all prior financial periods, were prepared in accordance with accounting
principles generally accepted in the United States ("U.S. GAAP"). IFRS differs in certain material respects from
U.S. GAAP and, accordingly, the consolidated financial statements for our financial years ended December 31, 2010
and 2009 prepared in accordance with IFRS as issued by IASB are not comparable to our consolidated financial
statements prepared in accordance with U.S. GAAP for 2009 and prior years presented in our reports on Form 20-F.
See "Item 5. Operating and Financial Review and Prospects--Change in Accounting from U.S. GAAP to IFRS" and
Note 4 to our consolidated financial statements included in Form 20-F annexed herein.
For certain purposes, such as providing reports to our Brazilian shareholders, filing financial statements with the
CVM and other distributions and tax liabilities in Brazil, we have prepared and will continue to be required to
prepare financial statements in accordance with the accounting principles required by Brazilian law No. 6,404, dated
December 15, 1976, as amended, (the "Brazilian Corporate Law"), and the rules and regulations of the CVM
("Brazilian GAAP").

OFFERING MEMORANDUM SUMMARY
The following summary is qualified in its entirety by, and is subject to, the more detailed information and the
financial statements (including the notes thereto) appearing elsewhere in this offering memorandum.
The Issuer
CSN Resources S.A. (the "Issuer") is a public limited liability company (société anonyme), incorporated under
the laws of Luxembourg on October 7, 2009, having its registered office at 9, rue Gabriel Lippmann, L-5365
Münsbach, registered with the Luxembourg Register of Commerce and Companies under number B148403, and is an
indirect subsidiary of CSN. The Issuer's activities will be limited by the terms of the Indenture. See "Description of
the Notes--Covenants--Negative Covenants." The Issuer has a share capital of 1,000,000 divided into 1,000,000
shares of par value 1.00 each, all of which have been issued, fully paid-up and are held by CSN Steel S.à.r.l., a
direct subsidiary of the Guarantor.
The Guarantor
General
We are one of the largest fully integrated steel producers in Brazil and Latin America in terms of crude steel
production. Our current annual crude steel capacity and rolled product capacity is 5.6 million and 5.1 million tons,
respectively. In 2011, production of crude steel and rolled steel products amounted to 4.9 million tons and 4.7
million tons respectively, both stable when compared to 2010. We also operate in the mining, cement, logistics and
energy businesses, which have become increasingly important to our operations and growth.
Steel
Our fully integrated manufacturing facilities produce a broad line of steel products, including slabs, hot- and
cold-rolled, galvanized and tin mill products for the distribution, packaging, automotive, home appliance and
construction industries. In 2010, we accounted for approximately 46% of the coated steel products market in Brazil.
We are also one of the world's leading producers of tin mill products for packaging containers, and were responsible
for approximately 100% of the market share in Brazil in 2010. Market share information for 2011 was not yet
available as of the date of this annual report.
Our production process is based on the integrated steelworks concept. Below is a brief summary of the steel
making process at our Presidente Vargas Steelworks:
Iron ore produced from our own mines is processed in continuous sintering machines to produce sinter;
Sinter and lump ore direct charges are smelted with lump coke and injected powdered coal in blast furnaces
to produce pig iron;
Pig iron is then refined into steel via basic oxygen converters;
Steel is continuously cast in slabs; and
Slabs are then hot rolled, producing hot bands that are coiled and sent to finishing facilities.
We currently obtain all of our iron ore, limestone and dolomite requirements, and a portion of our tin
requirements from our own mines. Using imported coal, we produce approximately 75% of our coke requirements at
current production levels in our own coke batteries at Volta Redonda. Imported coal is also pulverized and used
directly in the pig iron production process. Zinc, manganese ore, aluminum and a portion of our tin requirements are
purchased in local markets. Our steel production and distribution processes also require water, industrial gases,
