R$1,938,849,000 in principal amount of its Sixth Series of Debentures of First

4.   PURPOSE OF TRANSACTION

         The acquisition which required the original filing of this statement
was part of a larger transaction between certain shareholders of the Company and
certain indirect shareholders of CVRD to eliminate their cross-ownership in
these companies. The initial Stock Purchase and Sale Agreement, dated May 31,
2000, and the definitive Stock Purchase and Sale Agreement, dated December 31,
2000, by and among the shareholders of the Company named therein and the
shareholders of CVRD named therein, were attached to the original (paper) filing
of this statement as Exhibits II-A and II-B, respectively. As a result of the
consummation of these agreements, Vicunha Siderurgia became the direct owner of
46.5% of the issued and outstanding Shares of the Company, and Vicunha Steel and
Vicunha Acos became beneficial owners of such Shares.

         At the present time, none of the Reporting Persons and, to the best of
their knowledge, none of the persons listed on Schedule I hereto, have any plans
or proposals that relate to, or would result in, any of the transactions
described in paragraphs (a) - (j) of Item 4 of Schedule 13D, except as described
under Item 6.

5.   INTEREST IN SECURITIES OF THE ISSUER

(a) and (b)   Vicunha Siderurgia owns 33,337,090,988 Shares with the power to

              ownership of Vicunha Siderurgia, and Vicunha Steel, by virtue of
              its ownership of Vicunha Acos, share the power to vote and dispose
              of such Shares. No person listed on Schedule I hereto owns or has
              any interest in more than 1% of the outstanding Shares other than
              indirectly through their ownership of shares of Vicunha Steel.

6.   CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR
     RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER

         The shareholders' agreement dated April 23, 1993, as amended on March
27, 2000, which was described under this item in the original filing of this
statement, terminated on April 23, 2002.

         Pursuant to a Pre-Emption Agreement for the Acquisition of Stocks,
Participation in CSN's Control Premium ("the "Pre-Emption Agreement"), dated
March 9, 2001, by and among BNDES Participacoes S.A. ("BNDESPAR") and the
persons listed on Schedule I as controlling persons of Vicunha Steel, the
parties thereto have agreed to certain restrictions on transfers of Shares owned
by Vicunha Siderurgia.

         Pursuant to the Private Deed for Issuance of Non-Convertible Debentures
with Collateral Security and Reorganization Clause to the Sixth Series of
Debentures of First Issue of Vicunha Siderurgia S.A. (the "Deed"), among Vicunha
Siderurgia, as Issuer, Vicunha Acos, Vicunha Steel and the shareholders of
Vicunha Steel, as guarantors, BNDESPAR, the Company and the Trustee named
therein, Vicunha Siderurgia has pledged the Shares to guarantee the performance
of its obligations with respect to the Debentures. The Deed includes, among
other provisions, (i) restrictions on the transfer of Shares by Vicunha
Siderurgia, (ii) an agreement by Vicunha Siderurgia to maintain at least 46.5%
of all Shares of the Company subject to the pledge and (iii) an agreement by
Vicunha Siderurgia to cause the Company to pay annual cash dividends of at least
25% of the Company's adjusted net profit and to restrict the payment of non-cash
dividends. In addition, BNDESPAR, as long as it holds Debentures, may convert
Debentures into Shares at any time after 2 years from the date of issuance. In
the event of a default by Vicunha Siderurgia under the Deed, the Trustee may
sell the Shares subject to the pledge on behalf of the holders of the Debentures
in order to satisfy Vicunha Siderurgia's obligations under the Deed.

         The controlling persons of Vicunha Steel listed on Schedule I hereto
have an agreement which, among other things, restricts the transfer of their
shares of Vicunha Steel and establishes procedures for the election of directors
of Vicunha Steel.

         The descriptions of the Pre-Emption Agreement and the Deed above are
qualified by reference to copies thereof which were filed as Exhibits IV and V,
respectively, to the original (paper) filing of this statement and are
incorporated herein by reference.
