# Management’s Proposal

Dear Shareholders

Below is the Management's proposal of Companhia Siderúrgica Nacional (“Company”) on the matters to be resolved at the Annual Shareholders’ Meeting to be held on April 26, 2019, at 9:00 a.m., at the Company’s headquarters located at Av. Brigadeiro Faria Lima, 3400, 20º andar, in the City of São Paulo - SP (“ASM”), to resolve on the following agenda:

1. Analyze the management accounts, examine, discuss and vote on the Company’s financial statements and annual management report for the fiscal year ended on December 31, 2018.

We propose that the Company’s shareholders make an assessment of the management accounts and approve Financial Statements and Management Report for the fiscal year ended on December 31, 2018 (“Financial Statements”), as disclosed on February 20, 2019, on the websites of CVM (www.cvm.gov.br), B3 S.A. – Brasil, Bolsa, Balcão (www.b3.com.br) and the Company’s Investor Relations website (www.csn.com.br/ri/).

In addition, we also highlight, pursuant to Item III of Article 9 of CVM Instruction No. 481, of December 17, 2009 (“CVM Instruction 481/09”), as amended, that the information in Attachment I of this proposal reflects our comments on the Company's financial situation.

We clarify, as appropriate, that Financial Statements prepared by the Board of Executive Officers were considered adequate by the independent auditors, the Board of Directors, the Audit Committee and the Fiscal Council, according to the Opinions included in the Standardized Financial Statements, approved at the Meeting of the Audit Committee of February 20, 2019 and Fiscal Council Meeting of February 19, 2019, and minutes of the Meeting of the Board of Directors held on February 20, 2019, all disclosed by the Company on the websites of CVM and B3, through the Empresas.Net System and at CSN’s Investor Relations website.

2. Allocation of net income for the fiscal year ended on December 31, 2018 and distribution of dividends.

We propose that the income statement for the fiscal year ended on December 31, 2018, in the amount of R$ 5,074,135,973.74 be allocated as follows:

(i) R$ 1,291,688,999.34 to absorb accumulated losses of previous periods, with the respective full amortization of the Account of Accumulated Losses, pursuant to Article 30 of Paragraph 1of the Company’s Bylaws and Article 189, caput, of Law 6.404/76;

(ii) (ii) R$ 189,122,348.72 for the legal profit reserve account;

(iii) R$ 898,331,156.42 distributed to shareholders as minimum mandatory dividend, corresponding to R$ 0.65091 per share;

(iv)
R$ 2,694,993,469.26 as statutory reserve for working capital and investments.

The proposed allocation above was reflected in Explanatory Note 21 of the Company's Financial Statements and detailed in Attachment II of this proposal, which was elaborated in compliance with Item II of the Sole Paragraph of Article 9 of CVM Instruction 481/09.

3. Establish the number of members of the Board of Directors

It is proposed that the Board of Directors to be elected at the AGM be composed of 05 (five) members, one of them being the candidate indicated by the Company's employees, pursuant to art. 14 of the Bylaws.

8

The above-mentioned number of members may be increased by a decision to be taken by the shareholders at the AGM, including, but not limited to, the following: (i) adoption of multiple voting system with due compliance with legal requirements; or (ii) minority shareholders exercise the right to elect members of the Board of Directors in a separate vote; in all cases as long as the legal requirements are met.

4. Fixing of the administrators' overall annual compensation for the 2019 financial year

We propose that the compensation of the managers for the 2019 fiscal year be fixed in the global amount of up to R$ 83,176,000.00.

We hereby announce that, in regards to 2018, at the Annual General Meeting held on June 29, 2018 ("AGO 2018"), the amount of up to R$ 80,000,000.00 was approved for compensation but effectively realized in such period the amount of R$ 32,953,792.00.

The variation between the overall amount approved at the AGM 2018 and the amount actually realized in that year was mainly due to the impacts of the global macroeconomic situation, which caused the company to have a global compensation cost lower than initially projected.

We emphasize that the necessary information for the proper analysis of the proposal of the remuneration of the administrators, as established by art. 12 of CVM Instruction 481/09, are available in Annex III of this proposal.

5. Elect the members of the Board of Directors

We inform that the election of members to the Board of Directors will occur through the majority voting system, by single ticket, unless it is required to adopt multiple voting process.

The controlling shareholders of the Company informed Management that they will indicate the following ticket, for election of the members of the Board of Directors:

• Benjamin Steinbruch, administrator, enrolled with CPF/ MF under nº 618.266.778-87;

• Yoshiaki Nakano, administrator, enrolled with CPF/ MF under nº 049.414.548-04;

• Antonio Bernardo Vieira Maia, administrator, enrolled with CPF/ MF under nº 510.578.677-72; and

• Miguel Ethel Sobrinho, engineer, enter in the CPF / MF under number 332.816.028-00.

In addition, of the above candidates, under the terms of paragraph 2 of art. 14 of the Bylaws, a vacancy shall be reserved for the employee representative to serve on the Board of Directors.

If there is a request for adoption of the multiple voting process, each common share will be allocated as many votes as there are positions to be filled in the Company's Board of Directors, allowing the shareholder the right to accumulate votes in a single candidate or to distribute them among several candidates.

It should be noted that the request for adoption of the multiple vote must be made by shareholders representing at least 5% of the voting capital of the Company, by means of a written notice delivered to the Company within 48 (forty eight) hours before the AGM or through the Distance Voting Form. Once the request is received, the Company will disclose a Notice to Shareholders.

Law 6,404/ 76 also guarantees the right for shareholders to elect one (1) member of the Board of Directors in a separate vote, without the participation of the controlling shareholder, provided that they hold, individually or jointly, 10% (ten per cent) of the voting capital stock, observing the provisions of article 141, paragraph 6 of Law 6,404/ 76.

Accordingly, a shareholder who wishes to request a separate election, as well as to elect a separate member of the Board of Directors, shall, pursuant to article 141, paragraph 6 of Law 6404/76:

i. in case of attendance at the Meeting, present to the Company, together with other documents required for its accreditation, proof issued by the competent entity of the uninterrupted ownership of the shares, for a period of at least three (3) months, minimum, immediately preceding the AGM; or

9

ii. in case of participation by means of the remote voting form, send to the Company, at the electronic address invrel@csn.com.br, proof of the uninterrupted ownership of the shares, issued by the competent entity, during the period of 3 (three) months, at least, immediately prior to the AGM, and such confirmation shall only be considered valid if received in the above e-mail by 6:00 PM (Brasilia time) on April 25, 2019.

Without the evidence mentioned above, the shares will not be computed for the purpose of requesting separate election of a member of the Board of Directors.

As provided in item 10 o f the Distance Voting Form, a shareholder may only exercise the right of separate election if he/she has not opted for majority voting or the multiple voting system. Therefore, votes cast via the Distance Voting Form will not be considered if shareholders have requested the adoption of multiple vote process and separate election in the same ballot.

We clarify that, under the terms of art. 10 of CVM Instruction 481/09, the information regarding the candidates for the positions of members of the Board of Directors of the Company indicated above, as well as the employee's representative, are detailed in Annex IV of this proposal.

Finally, management informs that the Shareholders' participation in the AGM may be personal, by a duly constituted proxy or by sending a Distance Voting Form, pursuant to ICVM 481/09, as amended and in accordance with the instructions contained therein in the Manual for Participation in the General Meeting.

# Attachment I – Comments from Management

(pursuant to item 10 of Attachment 24 of 480/09)

Base Date: December 31, 2018

10. COMMENTS FROM MANAGEMENT

10.1 – The comments below refer to the consolidated financial statements of the Company for the year ended on December 31, 2018, December 31, 2017 and December 31, 2016.

a) overall financial and equity conditions
CSN is a diversified industrial group that operates through business units that integrate and complement each other, creating synergies and vertical and horizontal integration in its industrial chains. CSN’s main activities are the exploration and sale of iron ore, the production of flat and long steel, the manufacture of cement, among other products, integrated through logistics assets such as railways, ports and energy assets. The high quality of its assets and goods, combined with strong cost management and integration of productive units in Brazil and abroad, allow the generation of a higher value than the industry competitors and reduce the volatility of its results. The information in this item should be read and analyzed together with our consolidated financial statements available on our website (www.csn.com.br) and on the website of the Brazilian Securities and Exchange Commission (www.cvm.gov.br). On December 31, 2018, the Company presented a current liquidity ratio of 1.05, compared to 1.11 on December 31, 2017 and 2.26 on December 31, 2016. The 6% decrease in the liquidity ratio variation on December 31, 2018, compared to a fall of 51% in 2017 YoY, was due to the debt rollover renegotiations with Banco do Brasil and Caixa Econômica Federal, which shifted maturities from 2018 - 2023 to 2024, thus increasing our long-term debt profile, as shown in Explanitory Note 12 - Loans and Financing. The 51% decrese in December 31, 2017 was due to cash reduction for the payment of debt service, and the increase of short-term debt, which was partially renegotiated with Banco do Brasil and Caixa Econômica Federal, as described in Explanitory Note 32 – subsequent events. On December 31, 2018, the Company’s net debt totaled R$25.7 billion, versus R$25.4 billion on December 31, 2017, which represented an increase of 1%, mainly due to reduction in cash to amortize principal and interest, in the amount of R$7.2 billion, and an increase in debt by R$6.5 billion as a result of funding in the amount of R$2.2 billion and R$4.3 billion related to provisions for charges and foreign exchange variations, as detailed in Explanitory Note 12 - Loans and Financing. On December 31, 2016, net debt totaled R$248 billion. The following table reflects the Company's financial condition in the last three years: *Nota: The amount of loans and financing in the table above includes transaction costs, pursuant to the table in item 10.1 (f).

11

b) capital structure and possibility of redemption of shares or stocks
The Company seeks to optimize its capital structure in order to reduce its financial costs and maximize the return to its shareholders. The table below shows the evolution of the capital structure of the Company in the last three years, with funding from equity and third-party capital:
c) payment capacity regarding the financial commitments undertaken
The Company currently has a liquidity position that allows it to honor its short-term commitments. The Company's 2019 plan focuses on reducing disbursements, extending its debt amortization schedule and preserving cash. The following charts show the cash and cash equivalents against maturities of loans and financing on December 31, 2018, December 31, 2017 and December 31, 2016.

12

*Amounts referring to loans and financing include transaction costs.
d) funding sources used for the working capital and for investments in non-current assets
The funding sources used by the Company for working capital and for investment in non-current assets were trade finance lines, development bank lines, debt securities issued in foreign markets (bonds), debentures, and bank credit notes (CCB), sale of receivables, transfer of supplier credit, as well as own resources. These financing sources in the domestic and foreign markets are described in item 10.1(f). In 2018, we issued a Bond with maturity in 2023 and proceeds were used to repurchase Bonds maturing in 2019 and 2020. In addition, advances were made on the Exchange Contract (ACC) to guarantee the Company's short-term liquidity and vehicle financing through CDC (Direct Consumer Credit).
e) funding sources for working capital and investments in non-current assets that the Company intends to use to cover the liquidity shortfalls
The Executive Board believes that if it becomes necessary to cover any liquidity shortfalls, the Company may contract special credit lines, financing with banks and negotiate with its suppliers. Also has as its main purpose reducing the Company's financial leverage, therefore the Management is committed to a plan to sell a set of assets. The Company considers several sales scenarios that vary according to different macroeconomic and operational assumptions.

13

(iv) any restrictions imposed on the Company, in particular concerning debt limits and contracting new debt, distribution of dividends, disposal of assets, issuance of new securities and the sale of corporate control.

The financing contracted with FINEP (Financer of Studies and Projects) and certain agreements for the issue of insurance-guarantees provides that, among other provisions, any change in the control of the Company without the prior consent of FINEP or the insurer may lead to the early maturity of the financing or insurance-guarantee, as the case may be. Under the terms of the agreements governing the 5th, 7th, 8th and 9th issues of Debentures of the Company, among other provisions, the Company may not be merged, incorporated or split, unless the transaction has previously been approved by debenture holders holding at least 75% of the outstanding debentures (excluding intra-group transactions, with express provision in the debentures deed), or if the holders are assured the redemption of the debentures, for their nominal value plus a compensation, at least 6 months after the disclosure of the minutes of the shareholders’ meeting resolving on the transaction. Certain bonds issued by subsidiaries of the Company abroad (“Notes”) provide that, among other provisions, the Company, as guarantor, may not: (i) merge, be incorporated or sell all or a substantial part of its assets to third parties, except if the Company is the entity resulting from this corporate reorganization or if this entity is a company based in Brazil, in any country of the European Union or in the United States, that undertakes the guarantor obligations; (ii) encumber its assets, except as permitted in the issuance documents; and (iii) contract new debts, except as permitted in the issuance documents.

Comparison of Results for the fiscal years ended on December 31, 2018 and December 31, 2017: # Net Revenue from Sales and/or Services In the fiscal year ended on December 31, 2018, net revenue reached R$22,968 million, 24% higher than the amounts recorded in 2017. This increase was a result of the improvement in the steel sales volume, mining sales and better average prices for iron ore due to the Platts appreciation. Cost of goods and services sold In the fiscal year ended on December 31, 2018, the consolidated cost of goods sold (“COGS”) reached R$16,106 million, up by 18% when compared to the amounts in 2017. This result is justified by the increase in raw material prices, the impact from the appreciation of the US dollar against the real in the period (+18.5%) and the increase in volumes. Gross Income (Loss) In the fiscal year ended on December 31, 2018, gross profit totaled R$6,863 million, up by 39% over 2017, due to the reasons described above. Other Revenues (Expenses), net In the fiscal year ended on December 31, 2018, the account of “Other Operating Revenues and Expenses” totaled a positive amount of R$2,705 million. The positive effect was due to the sale of the Heartland Steel Processing LLC subsidiary to Steel Dynamics (SDI) for R$1.164 million, increase in value of shares classified as fair value in the profit and loss account (resulting in an approximate gain of R$1,655 million) and R$1,102 million in the recognition of the non-inclusion of ICMS tax in the previous years, generating recoverable taxes. As for Operating Expenses, we highlight an increase by R$104 million in reference to the contractual amendment with the parent company MRS, related to the revision of the "Annual Transportation Plan", R$278 million as a result of a cash flow hedge, loss of inventories in the amount of R$ 134 million, expenses with environmental liabilities by nearly R$53 million, and R$23 million in provisions for industrial restructuring. Equity Income Equity Income in 2018 was R$136 million, an increase by R$109 million of the amounts recorded in 2017. This was mainly due to the improved results at MRS Logística S.A. (“MRS”). Net Financial Income In the fiscal year ended on December 31, 2018 the Company's net financial result was negative by R$1,496 million and R$ 2,464 million in 2017. The elements that influenced results in 2018 were mainly caused by the monetary restatement referring to the recognition of the exclusion of ICMS in the calculation basis of PIS and COFINS of previous years, in the amount of R$1.106 million. Financial expenses fell sharply in the period, due to the fall in SELIC, generating a reduction of approximately R$470 million.

21

Income Tax and Social Contribution - Current and Deferred In 2018, the reduction of income tax and social contribution expenses in the period is mainly due to the increase in deferred income tax and social contribution (IR/CS) due to the reversal of tax credits loss recorded in prior years, in the amount of R$97 million. Consolidated Net Profit (Loss) In view of the foregoing presented in the above items, in the fiscal year ended on December 31, 218, CSN recorded a consolidated net income of R$5,201 million. In 2017, the Company’s recorded consolidated net income was R$111 million.

Cost of goods and services sold In the fiscal year ended on December 31, 2017, the consolidated cost of goods sold (“COGS”) totaled R$13,596 million, 7.6% higher than 2016, accompanying the lower sale volume in the mining segment and higher raw material prices in the steel segment. # Gross Income In the fiscal year ended on December 31, 2017, gross income reached R$4,928 million, up by 9.3% over the results achieved in 2016, due to the reasons described above. Other Revenues (Expenses), net In 2017, the account of “Other Operating Revenues and Expenses” came in positive by R$177 million, mainly due to the positive effect of the monetary restatement of the Eletrobrás loan and in 2016, the negative amount of R$413 million was due to the impairment of the fair value of Transnordestina Logística S.A. Equity Income Equity Income in 2017 was R$109 million, a R$65 million increase over 2016. This result is mainly due to the better results at MRS Logística S.A. (“MRS”) and a strong reduction in the losses that reflect in the equity income results of TLSA.

22

Net Financial Income In 2017, the Company's net financial result was a negative by R$2,464 million, compared to a negative net financial result of R$2,522 million in 2016, basically due to: • Reduction by R$541 million in financial expenses, going from R$3,283 million in 2016 to R$2,742 million in 2017, due to the CDI fluctuation on outstanding loans and financing. • Reduction by R$349 million in financial revenues, from R$644 million in 2016 to R$295 million in 2017, due to the fluctuation of the CDI on financial investments, reduction of cash and re-purchase of securities that in 2016. • R$133 million variation in expenses with monetary restatements, which went from a revenue of R$117 million in 2016, to an expense of R$16 million in 2017, mainly due to the US dollar. In 2016, Future Operations in US dollars were settled. Income Tax and Social Contribution - Current and Deferred The increase in income tax and social contribution expenses in the period is due to pre-tax income that resulted in an income tax expense of R$177 million and adjustments to reflect the effective tax rate. Further details are available on Note 16 to the Consolidated Financial Statements.

Its main products are 55% Al-Zn alloy coated steel, which combines gloss and durability, and pre-painted steel, both heavily applied in the construction and white goods sectors. Still, this unit can produce galvanized steel with pure zinc coating. CSN also has two subsidiaries abroad: (i) Lusosider Aços Planos SA, in Paio Pires, Portugal, operating in the pickling, cold rolling and galvanizing of flat steel, and (ii) Stahlwerk Thüringen GmbH ("SWT "), Located in Unterwellenborn, Germany, specializing in the production of steel profiles, with annual capacity of 1.1 million tons of steel profiles. The acquisition of SWT in January 2012 marked the Company's entry into the long steel segment. 2.1 - Presidente Vargas Plant The main steel unit of the Company, the Presidente Vargas Plant has an installed capacity of 5.6 million tons of crude steel per year, being 5.2 million tons in flat steel and 0.4 million in long steel. In 2018, crude steel production reached 3.8 million tons of flat steel and 0.2 million tons of long steel. In 2017, crude steel production reached 4.4 million tons of flat steel and 0.2 million tons of long steel and the production of flat rolled products reached 3.7 million tons. In 2016, crude steel production reached 3.0 million tons and the production of rolled products reached 3.2 million tons. 2.2- Porto Real Branch CSN’s branch in Porto Real/RJ produces galvanized steel, Galvanew® and blanks, mainly supplying the automotive industry.

32

2.4- Companhia Metalúrgica Prada Founded in 1936, Companhia Metalúrgica Prada (“Prada”) was acquired by CSN in 2006. Focused on the production of steel packaging and lithographic services, Prada has two plants located in São Paulo, including its lithographic center and the manufacture of packaging for chemicals and aerosols, and one plant in Uberlândia-MG, focused on food packaging, therefore, an important customer of tin plates of CSN. Prada also works in the distribution and services market. It currently has a Service Center and six distribution centers in the Southeastern region, including plates, blanks, rolls, UDC profiles, seamed pipes, steel deck and metal tiles for several segments of the industry. Its lines are able to meet the volumes and technical specifications required by the food, chemical, aerosol and services industries. In 2018, Prada sold 163 thousand tons of steel through the distribution segment. In 2017 and 2016, sales reached 174 thousand and 279 thousand tons, respectively. 2.5- Lusosider Aços Planos S.A. Installed in Aldeia de Paio Pires, Portugal, Lusosider Aços Planos S.A. works with cold rolling and galvanizing. In 2018, Lusosider produced 352 thousand tons of galvanized, cold rolled and Pickled/Oiled products, while in 2017 and 2016, these volumes reached 376 thousand and 333 thousand tons, respectively. 2.6- Stahlwerk Thüringen GmbH (SWT) In 2012, CSN acquired Stahlwerk Thüringen GmbH, consolidating its results from February of the same year. Located in Unterwellenborn, Germany, the plant specializes in the production of steel profiles, used in construction. In 2018, SWT sold 806 thousand tons of steel profiles This volume reached 808 thousand tons in 2017 and 782 thousand tons in 2016. 3. Logistics 3.1 Port Tecon, a container and cargo terminal, is managed by CSN's subsidiary, Sepetiba Tecon S.A. and handled 247 thousand containers in 2018, of which 584 thousand tons were steel products in addition to 210 thousand tons of general cargo. In 2017, 188 thousand containers were handled, being 989 thousand tons of steel products and 9 thousand tons of general cargo. In 2016, 140 mil thousand containers were handled, being 804 thousand tons of steel products and 14 thousand tons of general cargo.

33

3.2 Railway CSN has shareholdings of three railway companies: MRS Logística S.A. (“MRS”), FTL – Ferrovia Transnordestina Logística S.A. (“FTL”) and Transnordestina Logística S.A. (“TLSA”). MRS CSN owns, directly and indirectly, 34.94% of the share capital of MRS Logística, which operates the former Southeast Grid of the Ferroviária Federal S.A. (RFFSA), in the Rio de Janeiro - São Paulo - Belo Horizonte axis. MRS’ main segment of is heavy haul customers (ore, coal and coke cargoes), having transported approximately 119 million tons in 2018, equivalent to 68.2% of the total volume transported by the Company. In the container segment, MRS maintained its position among the largest carriers in the national rail sector, transporting 1.87 million containers in 2018, versus a volume of 1.84 million containers in 2017 and 1.78 million in 2016. The rail transportation services provided by MRS are key for the supply of raw materials and for the disposal of final products. The total volume of iron ore, coal and coke used by the Presidente Vargas Plant is transported by MRS, as well as part of the steel produced by CSN. FTL CSN owns 91.69% of the share capital of FTL, operator of the former Northeastern network of RFFSA, which covers seven states: Maranhão, Piauí, Ceará, Rio Grande do Norte, Paraíba, Pernambuco and Alagoas, with a total extension of 4,238 km and an annual transportation capacity of 2 million tons/year, with highlights to the transportation of fuel, cement, pulp, coke, clinker, containers, among other products. TLSA The railroad project has an extension of 1,753 km, which will connect the rail terminal in Eliseu Martins (PI) to Portos de Suape (PE) and Pecém (CE), going through several cities in the states of Piauí, Pernambuco and Ceará. The estimated operating capacity of the railroad is of 30 million tons per year, and it will likely play a key role in the development of the Northeast region and create a logistical option for local economic development, in the segments of oil and byproducts, grain, mining, agriculture, among others. CSN's shareholding in TLSA was 46.30% on December 31, 2018, 46.30% on December 31, 2017 and 49.01% on December 31, 2016. 4. Energy Its energy assets are (i) Itá Hydroelectric Power Plant, in Santa Catarina, in which the Company has a 29.5% indirect shareholding, through its 48.75% interest in Itá Energética S.A., corresponding to an average of 197 MW; (ii) the Igarapava Hydroelectric Power Plant, in Minas Gerais, with an average of 24.37 MW, in which the Company has a 17.9% shareholding; and (iii) the Thermoelectric Co-Generation Power Plant at the Presidente Vargas Plant in Volta Redonda/RJ, with an installed capacity of 235.2 MW, and which uses residual gases from steel production as fuel.

34

Net Revenue of the Company The tables and charts below show the Company's consolidated net revenue: (ii) Factors that materially affected the operating results The Company's main sources of revenue come from the production and sale of steel products and iron ore. Thus, the economic activity level in Brazil and abroad has a strong influence on its results. The Company sells steel products mainly in the domestic market. Thus, one of the factors influencing the results is the pace of the growth of the domestic economy, especially in the segments that are more steel-intensive, such as automotive, appliances and civil construction. These industries are directly influenced by the availability and cost of consumer credit. The macroeconomic policy decisions, such as the interest rate level, or that affect credit, such as taxes or other mechanisms, are constantly monitored. The impact of infrastructure construction works also play a key role, whether related to special events such as the Olympics or to the growth of production segments such as oil or civil construction, PAC construction works, among others. Another factor is the balance of steel’s supply and demand in the world, which establishes the price levels and also affects the level of imports. In the mining business, the results are directly impacted by the global supply and demand of iron ore. The majority of the Company’s net revenue concerning the sale of iron ore are from exports, mainly to Asia, especially China. On the cost side, prices of steel coal and coke, pellets, metals such as aluminum, zinc and tin, as well as exchange rates, are significant in the steel production. In mining and logistics (rail transportation), the cost of fuel is important. In addition, since the Company has expansion projects, the cost of equipment and services is a key variable that must be monitored.
b) variations in revenues attributable to changes in prices, exchange rates, inflation, changes in volumes and introduction of new products and services
In the steel industry, besides international prices, exchange rates, import tariffs, domestic supply and demand may affect the prices of our products. In addition, inflation and exchange rate affect costs and revenues, and may impact the profitability of the business. In mining, the majority of our sales come from iron ore exports, therefore, are tied to international demands. The exchange rate is critical to establish the competitiveness of costs and establish the revenue. In cement, the revenue is in Reais and inflationary variations may impact the results. In this way, the exchange rate is less representative in this segment.

35

Given that the majority of the Company's revenues come from the steel and mining segments, the Company quantifies the effects of changes in volumes and prices on its revenues in these two segments. In 2018, net revenue reached R$22.3 billion, 24% higher than in 2017, mainly due to the higher prices and volumes of iron ore and steel. Steel net revenues totaled R$15,6 billion, or 67% of the consolidated net revenue, with sales of 5.1 million tons in steel, being 3.3 million in the domestic market and 1.7 million in the foreign market (considering exports and sales abroad through the subsidiaries Lusosider, CSN LLC and SWT). Mining net revenue totaled R$5.9 billion, accounting for 25% of consolidated net revenue, selling 35 million tons of iron ore. In 2017, net revenue reached R$18.5 billion, 8% higher than in 2016, due to price adjustments of steel products, while in the mining segment the increase was due to higher prices in iron ore. Steel net revenues totaled R$12.9 billion, or 70% of the consolidated net revenue, selling 4.9 million tons of steel, being 2.8 million in the domestic market and 2.1 million in the foreign market (considering exports and sales abroad through the subsidiaries Lusosider, CSN LLC and SWT). Mining net revenue totaled R$4.6 billion, accounting for 25% of consolidated net revenue, selling 33 million tons of iron ore. In 2016, net revenue reached R$17.1 billion, 12% higher than in 2015, mainly due to price adjustments of steel products, while in the mining segment sold higher volume, along with the increase in the international price of ore. Steel net revenues totaled R$11.5 billion, or 67% of the consolidated net revenue, selling 4.9 million tons of steel, 2.8 million in the domestic market and 2.1 million in the foreign market (considering exports and sales abroad through the subsidiaries Lusosider, CSN LLC and SWT). Mining net revenue totaled R$4,582, 27% of the consolidated net revenue, selling 36.9 million tons of iron ore, mainly in the foreign market.
c) impact of the inflation, changes in prices of key inputs and goods, exchange and interest rates in the operating and financial results of the Company
Part of the costs and expenses of the Company is in Real, with a clause of inflation adjustment in the agreements. As mentioned in item (a), the prices of certain inputs directly impact the Company's results, in particular: Coal, coke, pellets and metals for the steel business, in dollar; Fuels for the mining and rail transportation businesses; and Clinker for the cement business. In addition to the production inputs, another key factor is the price of equipment and services, since the Company has a substantial portfolio of investment projects in all its business areas. The Company is exposed to the risks of interest and exchange rate on its loans, financing and financial investments. The available financial resources are invested in investment funds that include purchase and sale commitments backed by private and public securities with pre-established fixed income and with immediate liquidity. The private securities are financial investments in Bank Deposit Certificates (CDB) with yields connected to the variation of Interbank Deposit Certificates (CDI) and the public securities are basically purchase and sale commitments backed by National Treasury Notes. In addition, the Company also invests part of its financial resources abroad in Time Deposits with pre-established rates. CSN has debt in foreign currency and national currency, with pre- and post-fixed rates. On December 31, 2018, 43,9% of the debt was is reais and the other 56,1% was in other currencies. On December 31, 2017, 49.8% of the debt was in reais and the other 50.2% was in other currencies.

36

On December 31, 2016, 52% of the debt was in reais and the other 48% was in other currencies. The debt is connected to London Interbank Offered Rate (Libor), to CDI (Interbank Deposit Certificate) and to TJLP (Long Term Interest Rate). On December 31, 2018, approximately 60,2% of total debt was tied to the floating interest rate (Libor, TJLP, and CDI), versus 65,3% on December 31, 2017. The consolidated net foreign exchange exposure on December 31, 2017 is shown in the table below: It should be noted that CSN uses several instruments to protect itself from the risk of the exchange and interest rate.

10.3 Significant effects created or that will likely create by the following events in the Company's financial statements and results:

a) introduction or disposal of an operating segment
In 2018, there was no introduction or disposal of operating segment.
b) creation, acquisition or sale of shareholding
During the second quarter of 2018, CSN communicated its shareholders and the market, through a Material Fact, the sale by its wholly-owned subsidiary CSN Steel SLU of its interest in Heartland Steel Processing, LLC, the new corporate name of Companhia Siderúrgica Nacional LLC ("LLC") to Steel Dynamics, Inc. ("SDI"), which was approved on the same date by the Board of Directors. The LLC is located in the United States and operates in the pickling, cold rolling and galvanizing of flat steel. Also in the second quarter of 2018, after fulfilling all the conditions defined in the sale and purchase agreement signed with SDI, the Company concluded the transaction by transferring the equity interest and receiving the base transaction price, adjusted in US$400 million, as shown below:

37

(*) The transaction as concluded in September 2018. The final price amounted to U$37,589 thousand, equivalent to R$145,529. The sale of the LLC generated a cumulative gain of R$1,164,294 in the year.
c) unusual events or transactions
In 2018, there were no unusual events or transactions that significantly affected the Company's business.

10.4

a) significant changes in accounting practices
The table below lists the standards and interpretations issued by IASB (International Accounting Standard Board), but that have not yet come into effect and have not been adopted in advance by the Company for the year ended on December 31, 2018, since the adoption is not allowed for entities that disclose their financial statements in accordance with the accounting practices adopted in Brazil. To date, the impacts of the new standards are under study and evaluation and, therefore, the Management is unable to establish the qualitative and quantitative effects of the application of these standards. In addition to those listed below, there are no other standards and interpretations issued and not yet adopted that may, in the Management's opinion, have a significant impact on the results or equity disclosed by the Company.
Standard | Main points introduced by the standard | Comes into effect on |
IFRS16 – Leasing Operations | This new standard defines the principles for recognizing, measuring, presentation and disclosure of leases (leasing) and introduces a single model for the lessees to record leases in the balance sheet. A lessee recognizes the right of an asset to be used and represents this lease right and the lease liability for the obligation to make lease payments. Optional exemptions are available for short-term leases and low value items. For landlords, the accounting treatment remains practically the same, with the classification of leases as operating leases or financial leases. | January 1, 2019 |
IFRS 16 replaces the existing leasing rules, including IAS 17 / CPC 06(R1) – Leasing operations and ICPC 03 (IFRIC 4, SIC 5 and SIC 27) – Complementary aspects of leasing operations. |
IFRIC 23 – Uncertainties on Tax Treatments over Profits | How to apply tax legislation to a particular transaction or situation is not always clear. This standard complements CPC 32/ IAS 12 – Taxes on profit, clarifying how to reflect the effects of uncertainty in the accounting of taxes on profit. | January 1, 2019 |
Conceptual Framework for Financial Reporting | Reviews the Conceptual Framework by establishing a comprehensive set of concepts to guide financial performance reporting, better definitions and guidelines, highlighting the definition of a liability and clarifying relevant areas. | January 1, 2020 |

38

The following are information on the possible impacts when adopting IFRS 16/CPC 06 - Leasing Operation, and IFRIC 13/ICPC 22 - Uncertainties on tax treatments on Profit were available in the preparation of the financial statements. Accordingly, these preliminary assessments and their potential impacts are subject to change until the initial adoption is disclosed in the 2019 financial statements. - IFRS 16 /CPC 06 - Leasing Operations IFRS 16 / CPC 06 (R2) aims to unify the accounting model for leasing operations, requiring lessees to recognize assets and liabilities of all leases at present value, unless it has the following characteristics that are exemptions to the rule: (i) contract with a term of less than twelve months; and ii) the object of the lease has an immaterial value or is based on variable values. The Company concluded that with the adoption of the standard, it will reduce operating expenses and increase financial expenses, once the asset’s "right of use" is amortized and the lease liability is updated to reflect the amount to be paid over the lease period. The standard is applicable as of January 1, 2019 and the Company opted to apply the simplified retrospective approach, recognizing the cumulative effect as an adjustment in the beginning balance. The company estimates an impact of R$23 million on the parent company and R$578 million on the consolidated results with the initial recognition of lease rights and lease liabilities. - IFRIC 23 /ICPC 22 - Uncertainties on tax treatments over Profits This interpretation aims to clarify how a company should assess the accounting uncertainties in for taxes on profit when the applicable legislation is not clear. The company evaluated current events and the accounting treatment applied in each situation in the light of this interpretation, we concluded that IFRIC 23 does not have effects arising from tax positions adopted that may be challenged by the Brazilian tax authorities.

b) significant effects of changes in accounting practices
As of January 1, 2018, the Company began to adopt accounting norms IFRS 15 (CPC 47) – Revenues from Contracts with Customers and IFRS 9 (CPC 48) – Financial Instruments. With respect to IFRS 15, the Company identified after the analysis of the topic "identification of performance obligations" that the freight service in the CRF and CIF modalities will be considered a separate service and, therefore, a separate performance obligation, with allocation of part of the price of the transaction recognized in the result, according to the effective rendering of service over time. The effect of the difference in the recognition of the portion of revenue allocated to freight does not significantly affect the results of the Company's fiscal year. Therefore, such revenue will not be presented separately in the Company's financial statements. In the other topics of the new standard, the Company did not identify material impacts on the application of this standard. The observed impacts are related to a review of internal processes, with the objective of ensuring that new contracts with clients are properly evaluated and accounted for within the scope of the principles of the new standard. With respect to IFRS 9, the Company’s management evaluated the classification and measurement of the financial assets offered by the new standard based based on its business model, cash flow expectations and financial assets management model. Thus, the Company concluded that its investment in shares of Usiminas would be appropriately classified in the "fair value through profit and loss" category and that loans and receivables would be classified in the "amortized cost" category.

39

In the "fair value through profit or loss" category, the gains or losses arising from the share prices are recorded directly in the result at the time of adoption and throughout all future periods. In turn, as it was an initial adoption, the Company assessed the possible impacts related to the investment in shares of Usiminas and the credit balance accumulated in December 2017 as other comprehensive income, in the amount of R$1,559,682, was reclassified to the result based on the new standard. The IFRS 9 also includes new hedge accounting practices, which generally do not change, but fundamentally the types of hedge relationships or requirements for measurement and recognition of ineffectiveness. These changes did not have an impact on the Company.
c) reservations and emphasis in the auditor's legal opinion:
Reservations We report that there are no reservations in the independent auditors' reports regarding the 2018, 2017 and 2016 fiscal years. Emphasis During the last three years the jointly controlled subsidiary Transnordestina Logística S.A. was mentioned in the opinion of the independent auditors, specifically in the emphasis paragraph. We comment below the independent auditors' report for the 2018, 2017 and 2016 financial years. 1. Operational continuity of the jointly controlled subsidiary Transnordestina Logística S.A. We refer to Note 9.d) to the individual and consolidated financial statements, which describes the stage of completion of the new rail network of the jointly controlled subsidiary Transnordestina Logística SA ("TLSA"), currently under construction, and whose deadline for the completion of the work, originally scheduled for January 2017, is currently under review and discussion with the responsible government agencies. The completion of the projected works (and the subsequent start of operations) depend on the continued availability of funding from shareholders and third parties. These events and conditions, along with other matters described in the aforementioned explanatory note, indicate the existence of material uncertainty that may raise significant doubt as to the operational continuity of TLSA. Our opinion is not qualified in relation to this matter. We discuss below the emphasis paragraphs in the independent auditors' report for the 2016 fiscal year. 2. Restatement of financial statements of December 31, 2015 At the end of 2016, the Company decided to review the accounting treatment given to the transaction made by the Company on November 30, 2015 and concluded on December 31, 2015, which resulted in the combination of the mining and related logistics businesses of its subsidiary CSN Mineração S.A. (former Congonhas Minérios S.A.) and Nacional Minérios S.A. (NAMISA), with no change in its business structure, which led to significant adjustments and, therefore, the need to restate the financial statements for the year ended on December 31, 2015. It should be noted that these financial statements, in turn, had already been voluntarily restated on November 14, 2016 due to the change of the interpretation of Technical Pronouncement CPC 15/IFRS 3 - Business Combination identified during discussions of the Company with its independent auditors on the accounting procedure for the presentation of the item of interest of non-controlling shareholders of CSN Mineração S.A. in the consolidated financial statements. With the reopening of the financial statements for the year ended on December 31, 2015, there was a detailed review of the transaction of the aforementioned business combination, as well as a thorough review of several items and transactions, including studies to support the recognition and maintenance of the amounts of long-term assets, such as investments in subsidiaries and affiliates, goodwill, property, plant and equipment and tax credits.

40

Due to this review, one long-term asset that depends on estimates with observable premises was re-evaluated and, in turn, had its forecast of actualization adjusted. Thus, the financial statements for the year ended on December 31, 2015, originally dated of March 28, 2016 and resubmitted on November 14, 2016 due to the adjustments in the non-controlling shareholders’ interest, were restated for the second time as a result of the detailed reviews mentioned above. Operational continuity of the jointly-owned subsidiary Transnordestina Logística S.A. Explanatory note No. 10.d) of the financial statements for the year ended on December 31, 2016, describes the stage of completion of the new railway network of the jointly-owned subsidiary Transnordestina Logística S.A. (“TLSA”), currently under construction, and whose deadline for completion of the project, initially scheduled for January 2017, is currently under review and discussion with government agencies. The completion of the project’s construction works, and the consequent start-up depend on the continued availability of resources from its shareholders and third parties. In this sense, TLSA carried out an impairment test of its own long-term assets using the discounted cash flow method. In addition, CSN, as an investor, carried out an impairment test of its interest in TLSA through the dividend distribution capacity of TLSA, a methodology known as Dividend Discount Model, or DDM, to remunerate the capital invested by its shareholders. Further details on the impairment test and assumptions used are included in explanatory note n.10.d) of the financial statements for the year ended on December 31, 2016. As a result of the test carried out, the Company recognized a loss in the value-added of the investment of TLSA in the amount of R$387,989 thousand recorded in other operating and R$131,916 thousand in deferred taxes.

10.5 The officers must appoint and comment on the Company's key accounting policies, in particular the accounting estimates made by management on matters that are uncertain and significant to the description of the financial situation and results that require subjective or complex evaluation, such as: provisions, contingencies, revenue accounting, tax credits, long-term assets, useful lives of non-current assets, pension plans, exchange adjustments to foreign currency, costs with environmental recovery, criteria for the test of assets recovery and financial instruments

Key accounting policies of the Company:
The preparation of the financial statements in accordance with International Financial Reporting Standards (IFRS) and the standards issued by the Accounting Pronouncements Committee (CPC - Comitê de Pronunciamentos Contábeis) require the use of certain accounting estimates and also the evaluation of the management in the application of the Company's accounting policies. The estimates are based on the best current knowledge of each fiscal year. Changes in facts and circumstances may lead to a review of these estimates. Actual future results may differ from these estimates. The significant assumptions and estimates that, in the evaluation of the Company's management, require deeper evaluation or are more complex in order to prepare the financial statements, are as follows:

41

(a) Cash and Cash Equivalents Cash and cash equivalents include cash, bank deposits and other short-term investments of immediate liquidity, redeemable within 90 days after being contracted, promptly convertible into an amount known as cash and with insignificant risk of change in its market value. Bank certificates of deposit and government bonds that do not meet the criteria above are not considered cash equivalents and are classified as financial investments. (b) Fair Value of Business Combination The identifiable assets acquired, and liabilities undertaken in a business combination are measured at fair values at the acquisition date, as required by CPC 15 (R1) “Business Combination”. Consequently, when establishing the allocation of the purchase price, the fair values of certain items are adjusted, such as inventories, property, plant and equipment, mines, actual value of non-current assets and liabilities, among others, which are established by valuation reports made by independent evaluators. As of acquisition date, the Company has a maximum term of 12 months (measurement period) to account other (better) information on the fair value accounted on the acquisition date. The acquisition method is used to account for each business combination carried out. The Company accounts the noncontrolling interest in its financial statements, by the proportional percentage of the fair value of the net assets of the acquiree. Goodwill is represented by the positive difference between the amount paid and/or payable for the acquisition of a business and the net amount of the fair value of the assets and liabilities of the subsidiary acquired. If there is a gain due to an advantageous purchase, the Company must immediately account the result for the period, at the acquisition date. (c) Asset’s Useful Life Depreciation is calculated by the linear method based on the remaining useful life of the assets. The useful lives initially established by independent experts are reviewed, at least every year, for all units. If there are parts of a fixed asset with different useful lives, these parts are accounted separately as items of property, plant and equipment. (d) Mineral Reserves and Useful Life of Mines Estimates of proven and likely reserves are periodically evaluated and updated. These reserves are established using geological assessment techniques generally accepted. The calculation of reserves requires the use of several assumptions by the mining team and changes in some of these assumptions may have a significant impact on the likely and proven reserves recorded and on the useful life of the mines. (e) Impairment Test of Tangible and Intangible Assets Assets that have an indefinite useful life, such as goodwill, are not subject to amortization and are tested annually to verify the impairment. Assets that are subject to amortization or depreciation are reviewed for impairment whenever events or changes in circumstances indicate that the book value may not be recoverable The amount accounted in an impairment loss corresponds to the book value of the asset that exceeds its recoverable value, this being the higher amount between the asset's fair value less costs to sell and its value in use. To carry out the impairment evaluation, the assets are grouped at the lowest levels for which there are separately identifiable cash inflows (Cash Generating Units - CGUs). Non-financial assets, except goodwill, that have been impaired are subsequently reviewed to verify a possible reversal of the impairment at the reporting date.

42

As December 31,2017, the Company classified equity instruments as available-for-sale, where gains and losses arising from changes in stock prices were recorded directly in shareholders' equity under the account "Other comprehensive income" and each significant decline in market value a loss for impairment was recognized as income. From the entry of CPC 48 / IFRS 9 in force on January 1, 2018, equity instruments held for trading should be classified at fair value through profit or loss (VJR). Accordingly, changes in fair value will be recognized directly in profit or loss. (f) Pension and Post-Employment Benefits The pension plans granted by the Company substantially cover all employees. The amounts recorded depend on several assumptions that are established by actuarial calculations, in accordance with CPC 33 (R1) - Employee’s benefits. These assumptions are described in note 28 of the Company's consolidated financial statements and include, among others, the return rate on investments and nominal salary growth. When the benefits of a plan are increased, the part of the increased benefit related to past employees’ service is accounted as profit or loss by the linear method over the average term until the benefits become vested. Under the condition of the benefits becoming vested, the expense is immediately accounted in the result. The Company opted to immediately account all actuarial gains and losses resulting from current benefit plans in other comprehensive results and subsequently transferred to accumulated profit or loss. In the event of extinction of the plan, the accumulated actuarial gains and losses are accounted in the result. The Company and some subsidiaries offered post-retirement health benefits to their employees. The expected costs of these benefits were accrued throughout the employment, using the same accounting methodology that is used for the current pension plan benefits. These obligations are evaluated annually with qualified independent actuaries. (g) Provisions Provisions for legal proceedings are account only when the possibility of loss is considered likely and the amount can be estimated with reasonable certainty. This estimation is carried out by the Company's management together with legal advisors. The estimates are duly recognized in our financial statements in accordance with CPC 25 - Provisions, Contingent Liabilities and Contingent Assets. The Company is also involved in legal and administrative proceedings in order to obtain or defend legal rights in tax matters that it deems unconstitutional and considers that the amounts should not be paid. The amounts accounted for these tax disputes and other contingencies may be subject to future changes, due to the developments in each case, such as changes in legislation or specific final court ruling for the Company. In the currently uncertain Brazilian legal environment, as well as in other jurisdictions, require the management to make estimates and evaluations regarding the results of future events. Other details on provisions can be found in explanatory note 16 of the Company's consolidated financial statements.

(h) Deferred Income Tax and Social Contribution The actual and deferred income tax and social contribution are calculated based on the tax laws enacted on the date of the balance sheet, including in countries where the Group operates and generates taxable income. The management periodically evaluates the positions taken in the ascertainment of income taxes, assessing situations in which the applicable tax regulations may have different interpretations. The Company establishes provisions, when appropriate, based on the estimated amounts of payment to the tax authorities. Actual and deferred taxes are accounted in the result, unless related to the business combination, or items accounted directly in the net equity. The actual tax is the event to be paid or expected to be received on the taxable profit or loss for the year at rates decreed on the date of submission of the financial statements and any adjustment to taxes payable concerning prior years. The deferred tax is established for temporary differences between the book value of assets and liabilities for accounting purposes and the corresponding amounts used for tax purposes. The deferred tax is not established for temporary differences from the initial accounting of assets and liabilities in a transaction that is not a business combination and does not affect the accounting profit nor loss or tax loss, and the differences concerning investments in subsidiaries when it is likely that they will not be reversed in the foreseeable future. In addition, the deferred tax liabilities are not established for temporary tax differences from the initial accounting of goodwill. The deferred tax is measured by applying the rates that are expected to be applied to temporary differences when they are reversed, based on the laws issued up to the date of submission of the financial statements. The actual tax income and social contribution are submitted as net, by the taxpayer, in liabilities when there are amounts payable, or in assets when the amounts paid in advance exceed the total amount due at the reporting date. The deferred tax assets and liabilities are offset if there is a legal right to offset actual tax liabilities and assets and they are related to income taxes levied by the same taxing authority on the same taxable entity. An asset of deferred income tax and social contribution is established for tax losses, tax credits and deductible temporary differences not used, in cases in which is likely that the future taxable income will be available and against which it will be used. A review is carried out annually to verify the existence of taxable future profits and a provision for loss is established when the realization of these credits is not likely in a period of less than 10 years. (i) Provisions for Doubtful Credits With the adoption of the new CPC 48 - Financial Instruments, the Company began to adopt the new model of expected losses during the term of receivables. These expected credit losses are estimated according to the maturity rate matrix by range, which is adopted by the Company from the initial date of an asset’s recognition. The Company considers customer history, default rate, financial position and the opinion of its legal advisors to estimate expected credit losses.

44

(j) Fair Value of Derivative Financial Instruments · Derivative instruments The Company accounts in its balance sheet all derivative financial instruments at fair value. Certain derivative instruments do not qualify for hedge accounting. The variation in the fair value of any of these derivative instruments are immediately included in the income statement under “financial result”. Regarding the measurement of the fair value, we must address factors such as the exchange rate and future interest rates. · Hedge activities The Company adopts the hedge accounting and establishes certain financial liabilities as hedging instruments for exchange rate risks connected to cash flows from expected and highly likely exports (cash flow hedge). At the beginning of the transaction, the Company documents the relationship between the hedging instruments and hedged items (expected exports), as well as the purposes of the risk management and the strategy to carry out several hedging transactions. The Company also documents its assessment, both at the start of the hedge and on an ongoing basis, that the hedge transactions are highly effective to offset variations in the cash flows of hedged items. The effective part of the changes in the fair value of the financial liabilities established and classified as cash flow hedges is accounted in the net equity under “Hedge Accounting”. Gains or losses related to the non-effective part are accounted as financial income, when applicable. The amounts accumulated in the equity are realized in the income statement for the periods in which the expected exports affect the result. When a hedge instrument prescribes or is settled in advance, or the hedge relationship no longer meets the Hedge Accounting criteria or if the Management decides to discontinue the Hedge Accounting, any cumulative gain or loss in the equity remains accounted in the net equity. When the expected transaction is carried out, the gain or loss will be reclassified as result. When an expected transaction is no longer expected, the cumulative gain or loss accounted in the net equity is immediately transferred to the income statement under “Other Operating”.

For the Assembly to be convened in first call, the quorum provided for in Article 125 of Law 6.404/76 must be complied with, i.e., the attending shareholders must represent at least 1/4 (one fourth) of the voting share capital. In second call, the shareholders’ meeting will be installed with any number of attending shareholders.

## PARTICIPATION

All shareholders who own common shares issued by CSN may participate in the Assembly in one of the two following manners: (i) On-Site: in person or through a representative with power of attorney; or (ii) Remotely: through the submission of the Remote Voting Form, pursuant to CVM Instruction 481/09, as amended (“ICVM 481/09”).

Those attending the Meeting must prove that they are shareholder of the company, by observing the following rules:

(i) On-Site Participation

The participation at the meeting will be considered on-site when the shareholder attends the meeting’s venue in person or represented by a proxy, and states his/her vote, according to the matters listed in the agenda.

To this end, in accordance with Article 126 of Law 6.404/76, the shareholder must show the following documents:

a) Individual Shareholder:

· Valid identity with photo of the shareholder, being considered proof of identity: RG, RNE, CNH, Passport and identity cards issued by professional councils (copy accompanied by the original copy or certified copy); and

80

· Updated statement showing the ownership of the issued shares and his/her shareholding, issued by the depositary financial institution and/or custody agent.

b) Corporate or Investment Fund Shareholder:

· Bylaws, articles of Incorporation or fund regulation, as the case may be (copy with the original document or certified copy);

· Statute or by-laws of the fund administrator or fund manager, as the case may be, subject to the fund's voting policy (copy accompanied by the original or authenticated copy)

· Document proving that people attending the meeting are duly invested as legal representatives of the legal entity or of the investment fund, with, for example, minutes of the election of the administrators (copy with the original document or certified copy);

· Identity document or driver’s license (original or certified copy) of the people attending the meeting as representative of the legal entity or of the investment fund; and

· Updated statement showing the ownership of the issued shares and his/her shareholding, issued by the depositary financial institution and/or custody agent.

c) Power of Attorney

If the shareholder, individual or firm, has constituted a legal representative to act as its proxy and exercise its right to attend and vote at the Meeting, the power of attorney must observe the following requirements:

· The attorney-in-fact must have been appointed less than one year prior;

· The signature of the power of attorney must be notarized; and,

· The power of attorney must be presented with the following supporting documents: documents proving the quality of the representative and of the represented person (certified copy of the identity document, if an individual, and certified copy of the bylaws/articles of incorporation and the minutes of the election of the members of the management, if a legal entity) and specific powers to participate in the meeting.

· The power of attorney must grant specific powers to participate in an assembly.

The original document or certified copy of the power of attorney must be send to the Company's headquarters up to 48 (forty-eight) hours before the time set for the assembly, according to article 11 of the By Laws.

81

Shareholders' representatives whose shares are in custody must also present an updated statement provided by the custodian or depositary financial institution containing the respective shareholding status.

The Company does not accept proxies granted electronically.

For shareholders domiciled abroad, all documents submitted must be translated and legalized by the Brazilian Consulate of their home country or filed at the authorized notary registry with the due Haya Apostille, so that all copies are certified, and all the signatures are notarized.

Before joining the meeting, the documents submitted by the shareholder will be analyzed to verify his/her identity and to validate the shareholder status to participate at the event. Accordingly, we request that shareholders arrive in advance of said Meeting so that documents can be checked in a timely manner. If the requirements stated above are not observed or if there is any inconsistency in the documents presented or even if the shareholding is not proved, the person will not be able to join the Meeting room.

After the documents are verified, the shareholders will sign the Attendance Book of Shareholders, which will be filed at the Company’s headquarters and will prove their participation in the respective Meeting.

After the start of the Shareholders’ Meeting, the shareholder may pose any question to the Chairman, who will be available to clarify any doubts during the Meeting.

(ii) Remote Participation (Remote Voting Form)

Pursuant to CVMI 481/09, the Company will adopt for this Meeting the remote voting form, providing to the shareholders another method to participate at the meeting.

As a result, shareholders may opt for exercising their voting rights through a document called the Remote Voting Form (“RVF”), which may be completed with the shareholder’s voting instructions and sent in 7 (seven) days prior to the Assembly, or until April, 19 2019 (It is suggested that the dates and instructions established by the custodian or book-keeper for the receipt of the Form to be confirmed, considering that April 19, 2019 will be a national holiday): (a) directly to the Company, to the Investor Relations Officer, at the address of CSN’s headquarters; or (b) authorized service providers (custody or bookkeeping agents), who will forward the voting statements to the central depository; or (c) the Company’s custodian.

If the shareholder is an individual or legal entity domiciled abroad, all documents submitted must be translated and legalized before the Brazilian Consulate in his/her country of domicile or apostilled in an authorized notary with the appropriate Hague Handbook, so that all copies are authenticated and all signatures have signature recognition.

b. Submission to the respective custodian agents, in the case of shareholders holding shares in central depository:

This option is exclusively for shareholders holding shares held by the central depositary - i.e., with B3. In this case, distance voting shall be exercised by the shareholders in accordance with the procedures adopted by their respective custodian agents.

83

The shareholder who holds shares deposited with the B3 Depository Center and who elects to exercise his/her right to vote at a distance through service providers must transmit his/her voting instructions to his/her respective custodian agents, observing the rules determined by them, who, in turn, shall forward such statements of vote to the Central Depositary of B3.

c. Sending to the Company's registrar

The company has no electronic system to receive the RVF or any other type of remote voting method.

84

If the RVF is partially or incorrectly completed, the Company will compute only the items that have been correctly completed or rectified in a timely manner, specifically rejecting the items presenting filing problems.

In addition, the RVF will be available together with other documents that are part of the Assembly, at the headquarters of CSN, as well as on the websites of the Brazilian Securities and Exchange Commission (www.cvm.gov.br), of B3 S.A. – Brasil, Bolsa e Balcão (www.b3.com.br) and at the Company’s Investor Relations (www.csn.com.br/ri), and must be received by the Company with the voting instructions up to seven (7) days before the date of the Shareholders’ Meeting.
