ITEM 1. SECURITY AND ISSUER

This Amendment No. 1 to Schedule 13D (this “Amendment”) relates to the common shares, no par value (the “Common Shares”), of Oi S.A. (formerly known as Brasil Telecom, S.A. (“Brasil Telecom”)), a corporation (sociedade anônima) organized under the laws of the federative Republic of Brazil (“Brazil”), which has its principal executive offices located at Rua General Polidoro, No. 99, 5th floor, Botafogo, 22280-001 Rio de Janeiro, RJ, Brazil (the “Issuer”).

ITEM 2. IDENTITY AND BACKGROUND

Item 2 is hereby amended and restated in its entirety as follows:

This Amendment amends the Schedule 13D filed with the Securities and Exchange Commission on November 17, 2009 (the “Initial 13D” and as amended by this Amendment, this “Statement”) by Telemar Participações S.A. (“TmarPart”), Tele Norte Leste Participações S.A. (“TNL”), Telemar Norte Leste S.A. (“Telemar” and together with TmarPart and Valverde Participações S.A. (“Valverde”), a wholly-owned subsidiary of TmarPart, the “Reporting Persons”) and Coari Participações S.A. (“Coari” and together with TNL, Telemar and the Issuer, the “Oi Companies”) by furnishing the information set forth below. Except as otherwise specified in this Amendment, all previous Items are unchanged. Capitalized terms used herein which are not defined herein have the meanings given to them in the Initial 13D.

This Amendment reflects (1) the decrease in TmarPart’s and Valverde’s beneficial ownership of the Common Shares as a result of the corporate reorganization of the Oi Companies described in Item 4 below (the “Corporate Reorganization”) and (2) that, as a result of the Corporate Reorganization, Telemar became a wholly-owned subsidiary of the Issuer and TNL and Coari ceased to exist.

This Amendment is being filed jointly on behalf of each of the Reporting Persons. The agreement among the Reporting Persons to file this Amendment jointly in accordance with Rule 13d-1(k) of the Securities Exchange Act of 1934 is attached as Exhibit 99.1.

TmarPart is a corporation (sociedade anônima) organized under the laws of Brazil principally engaged, through its subsidiaries, in providing telecommunications services to customers in Brazil. The principal office of TmarPart is Praia de Botafogo 300, 11th floor, sala 1101 (parte) 22250-040, Rio de Janeiro, RJ, Brazil.

Valverde is a corporation (sociedade anônima) organized under the laws of Brazil principally engaged in holding shares of the Issuer. The principal office of Valverde is Praia de Botafogo 300, 11th floor, sala 1101 (parte) 22250-040, Rio de Janeiro, RJ, Brazil.

Telemar is a corporation (sociedade anônima) organized under the laws of Brazil principally engaged, through its subsidiaries, in providing telecommunications services to customers in Brazil. The principal office of Telemar is Rua Humberto de Campos, 425 – 8th Floor Leblon, Rio de Janeiro RJ 22430-190 Brazil.

The name, present principal occupation or employment (and the name, principal business and address of any corporation or other organization in which such employment is conducted) and citizenship of each director and executive officer, as applicable, of each Reporting Person is provided in Exhibit 99.2, which is incorporated by reference herein.

During the last five years, neither the Reporting Persons nor, to the knowledge of the Reporting Persons, any of the persons listed in Exhibit 99.2 has (i) been convicted in any criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction such that, as a result of such proceeding, such person was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activity subject to, federal or state securities laws or finding any violation with respect to such laws.

ITEM 4. PURPOSE OF TRANSACTION

Item 4 is hereby amended and restated in its entirety as follows:

The merger of Brasil Telecom Holding with and into Brasil Telecom described in Item 3 was the first step in a proposed corporate reorganization that Telemar and its subsidiaries that control Brasil Telecom expected to undertake to reorganize Telemar’s interests in Brasil Telecom. That corporate reorganization was expected to be accomplished through three transactions that were to occur consecutively and would have cumulatively resulted in the conversion of the publicly held shares of Brasil Telecom Holding and Brasil Telecom into shares of Telemar: (1) the merger of Brasil Telecom Holding with and into Brasil Telecom, which was effectively completed on September 30, 2009, (2) a merger of shares (incorporação de ações) under Brazilian law in which shares of Coari, a wholly owned subsidiary of Telemar, would have been issued in exchange for shares of Brasil Telecom, other than shares of Brasil Telecom held directly by Coari, and (3) a merger (incorporação) under Brazilian law of Coari with and into Telemar, with Telemar as the surviving company.

On December 1, 2009, the Oi Companies announced the terms of the Coari share exchange. On January 14, 2010, the Oi Companies announced that they had decided to postpone the Coari share exchange, because the proposed exchange ratio for the subsequent merger of Coari into Telemar that had been announced on April 25, 2008 did not consider the effects of an increase of the provision for contingencies related to certain civil claims against Brasil Telecom in the gross amount of R$1,290 million, which Brasil Telecom was required to recognize in its financial statements for the year ended December 31, 2009.

On March 25, 2010, TNL and Telemar announced that the board of directors of Telemar had approved new exchange ratios for the merger of Coari into Telemar, adjusted to reflect the modification of the provision for contingencies related to certain civil claims against Brasil Telecom. On April 22, 2010, the board of directors of Brasil Telecom approved the new exchange ratios for the merger of Coari into Telemar, subject to the approval of the non-controlling holders of common and preferred shares of Brasil Telecom.

On June 16, 2010, the Oi Companies announced that at the general shareholders meeting of Brasil Telecom held on that date to consider the new exchange ratios for the merger of Coari into Telemar, the non-controlling holders of common and preferred shares of Brasil Telecom did not approve the new exchange ratios, and that, as a result, the remaining steps of the proposed corporate reorganization were indefinitely suspended.

On April 5, 2011, TmarPart began internal discussions regarding a new proposal to simplify the corporate structure of the Oi Companies. TmarPart engaged financial advisors and legal advisors during April 2011 to assist them in evaluating potential alternative corporate structures. These internal discussions continued during April and May 2011, becoming more frequent during May 2011. During April and May 2011, TNL and its subsidiaries provided information regarding the operations and financial condition of TNL and its subsidiaries to TmarPart to assist in evaluating the Corporate Reorganization.

As a result of these discussions, TmarPart publicly proposed the Corporate Reorganization on May 24, 2011. The Corporate Reorganization was effectively completed on February 27, 2012 and consisted of the following steps:

• a split-off and share exchange under Brazilian law in which (1) Telemar transferred the shares of Coari that Telemar owned to Coari, (2) Coari assumed a portion of the liabilities of Telemar (3) the Telemar common and preferred shares (other than the shares of holders who exercised their withdrawal rights with respect to such shares) were exchanged for newly issued common and preferred shares of Coari, and (4) Coari retained the Telemar shares exchanged for Coari shares and as a result, Telemar became a wholly-owned subsidiary of Coari;

• the merger of Coari into Brasil Telecom, resulting in Coari ceasing to exist and Telemar becoming a wholly-owned subsidiary of Brasil Telecom; and

• the merger of TNL into Brasil Telecom, resulting in TNL ceasing to exist.

In connection with the Corporate Reorganization, on February 24, 2012, TmarPart exchanged all of the class A preferred shares of Telemar that it owned for common shares of TNL held by Jereissati Telecom S.A., Andrade Gutierrez S.A. and Bratel Brasil S.A., each a shareholder of TmarPart, in order to ensure that upon the completion of the Corporate Reorganization, TmarPart retained the voting control of Brasil Telecom in order to comply with the legal and regulatory obligations of TmarPart to ANATEL.

6

In connection with the Corporate Reorganization, Brasil Telecom issued and distributed redeemable shares of Brasil Telecom to holders of Brasil Telecom shares prior to the mergers of Coari and TNL into Brasil Telecom and redeemed those shares for cash immediately following their issuance. In addition, Brasil Telecom was renamed Oi S.A.

The Corporate Reorganization was undertaken to:

• simplify the corporate structure of the Oi Companies, which was extremely complex and included three publicly-held companies with seven different classes of publicly-traded shares, and simplify the corporate governance of the Oi Companies by consolidating the shareholder bases of the Oi Companies in one public company with two classes of shares that will be traded in Brazil and abroad;

• reduce operational, administrative and financial costs following the consolidation of the general management of the Oi Companies, the simplification of their capital structure, and the improvement of their ability to attract investments and access the capital markets;

• align the interests of the shareholders of the Oi Companies;

• enhance the liquidity of the shares of Brasil Telecom; and

• eliminate the costs of separate listings of the shares of TNL, Telemar and Brasil Telecom, as well as those costs arising from separately complying with the public disclosure requirements applicable to TNL, Telemar and Brasil Telecom.

Other than as described in this statement, none of the Reporting Persons nor, to the Reporting Persons best knowledge, any of the persons listed in Exhibit 99.2 hereto, has any present plan or proposal that would relate to or result in any of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D. The Reporting Persons, however, retain their rights to acquire additional Common Shares, to sell some or all of the Common Shares or to modify their plans with respect to any matters of the type described in sections (a)-(j) of Item 4.

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

Item 6 is hereby amended and restated in its entirety as follows:

On April 25, 2008, TmarPart’s shareholders entered into two shareholders’ agreements: (1) the Shareholders’ Agreement among AG Telecom Participações S.A. (“AG Telecom”), LF Tel S.A. (“LF Tel”), Asseca Participações S.A. (“Asseca”), BNDES Participações S.A. (“BNDESPar”), Fiago Participações S.A. (“Fiago”), and Fundação Atlântico de Seguridade Social (“FASS”) as parties, with TmarPart, PREVI – Caixa de Previdência dos Funcionários do Banco do Brasil (“PREVI”), PETROS – Fundação Petrobrás de Seguridade Social (“PETROS”), FUNCEF – Fundação dos Economiários Federais (“FUNCEF”) and Andrade Gutierrez Investimentos em Telecomunicações S.A., as intervening parties (the “Global Shareholders’ Agreement”) and (2) the Shareholders’ Agreement among AG Telecom, LF Tel, Asseca and FASS as parties, with TmarPart and Andrade Gutierrez Investimentos em Telecomunicações S.A., as intervening parties (the “Control Group Shareholders’ Agreement”).

On June 20, 2008, the 352,730,590 common shares of TmarPart owned by Asseca were distributed to LF Tel and Andrade Gutierrez Investimentos em Telecomunicações S.A., with each receiving 176,365,295 common shares of TmarPart. As a result, Asseca is no longer a shareholder of TmarPart and has no rights under the Global Shareholders’ Agreement or the Control Group Shareholders’ Agreement.

In July 2009, Fiago distributed the shares of TmarPart that it held to PREVI, PETROS, FUNCEF and FASS. As a result of this distribution, Fiago is no longer a shareholder of TmarPart and has no rights under the Global Shareholders’ Agreement.

On January 25, 2011, TmarPart’s shareholders amended the Global Shareholders’ Agreement and the Control Group Shareholders’ Agreement to reflect the acquisition of voting shares of TmarPart by Bratel Brasil S.A. (“Bratel”) and to increase the quorum requirements to hold pre-meetings and approve certain designated matters. These amendments were effective as of March 28, 2011. The amendment to the Global Shareholders’ Agreement was entered into among AG Telecom, BNDESPar, PREVI, FASS, FUNCEF, PETROS, LF Tel and Bratel, as parties, with TmarPart and Portugal Telecom SGPS, as intervening parties. The amendment to the Control Group Shareholders’ Agreement was entered into among AG Telecom, LF Tel and FASS, as parties, with TmarPart, as intervening party.
