THE FOLLOWING ARE MATERIALS MADE PUBLIC BY TELEMAR PARTICIPAÇÕES S.A. (“TMARPART”) RELATING TO THE PROPOSED MERGER OF SHARES (INCORPORAÇÃO DE AÇÕES) BETWEEN TMARPART AND OI S.A. (“OI”).

EXHIBIT INDEX

Exhibit 1

MATERIAL FACT

Approval of the Terms of the Exchange of Credit for Shares of Oi/TmarPart and the Option for the Purchase of Shares in Treasury by the PT SGPS General Meeting and the Boards of Directors of TmarPart and Oi

Continuation of Final Stages of the Corporate Reorganization

Oi S.A. (“Oi,” Bovespa: OIBR3, OIBR4; NYSE: OIBR and OIBR.C) and Telemar Participações S.A. (“TmarPart” and, together with Oi, the “Companies”), pursuant to art. 157, § 4 of Law No. 6,404/76 (the “Corporation Law”) and CVM Instruction No. 358/02, in addition to the Material Fact dated July 28, 2014 and the Notices to the Market filed by Oi on August 8 and 13, 2014, inform their shareholders and the market in general that, on this date, the General Shareholders’ Meeting of Portugal Telecom SGPS S.A. (“PT SGPS”) and the Boards of Directors of Oi and TmarPart approved the terms and conditions of the definitive agreements related to the investments in commercial paper issued by Rio Forte Investments, S.A (“Commercial Paper”).

The definitive agreements were signed today among Oi, TmarPart and PT SGPS and provide for an exchange (the “Exchange”) in which Portugal Telecom International Finance B.V. (“PT Finance”) and PT Portugal SGPS S.A. (“PT Portugal” and, together with PT Finance, the “Oi Subsidiaries”) will transfer the Commercial Paper to PT SGPS in exchange for common and preferred shares of Oi held by PT SGPS, and the Oi Subsidiaries will grant PT SGPS an option to purchase shares of Oi (the “Option”), which will occur in accordance with the terms already disclosed to the market through the Material Fact of July 28 (the “Definitive Agreements”). Given the approval of the Definitive Agreements by the General Meeting of PT SGPS and the Boards of Directors of Oi and TmarPart, the implementation of the Exchange and of the Option will be subject only to the response of the Brazilian Securities and Exchange Commission (Comissão de Valores Mobiliários – CVM) to the consultation presented by the Companies with respect to these transactions.

The signing of the Definitive Agreements will enable the continuation of the combination of the businesses of Oi and PT SGPS (the “Transaction”), which will have as the next step the migration of TmarPart to the Novo Mercado of the São Paulo Stock Exchange (BM&FBOVESPA S.A. – Bolsa de Valores, Mercadorias e Futuros – BM&FBOVESPA), through the merger of shares between Oi and TmarPart (the “Merger of Shares”).

As preliminary steps to the Merger of Shares, the Companies will pursue (i) the registration of the shares to be issued by TmarPart in the Merger of Shares with the U.S. Securities and Exchange Commission (“SEC”), (ii) the conversion of TmarPart’s registration category as a publicly-held company, (iii) the registration of a Depositary Receipts Program of TmarPart with the SEC, (iv) the listing of the shares of TmarPart in Brazil on the Novo Mercado segment of the BM&FBOVESPA and in Portugal on the NYSE Euronext Lisbon, with the necessary approvals by the Portuguese Securities and Exchange Commission (Comissão do Mercado de Valores Mobiliários – CMVM) and by the NYSE Euronext Lisbon, and (v) the listing of the shares in the form of American Depositary Shares on the NYSE. As a result of the Exchange, the structure of the Transaction will no longer include the merger of PT SGPS into TmarPart.

On this date, certain agreements related to the Transaction and signed on February 19, 2014 were amended to provide, among other things: (i) the extension of deadlines for the completion of the Transaction; (ii) to clarify that the merger of PT SGPS with TmarPart will no longer occur within the scope of the Transaction (notwithstanding the fact that PT SGPS may adopt an alternative structure to achieve the same objective as the merger with respect to the combination of the shareholder bases of Oi and PT SGPS); and (iii) the limitation of the voting rights of PT SGPS, in the Bylaws of TmarPart, to a maximum of 7.5% of its capital stock.

The Companies reiterate that the Transaction is intended to migrate TmarPart to the Novo Mercado segment of BM&FBOVESPA, with the adoption of best corporate governance practices, admission of the TmarPart shares on the NYSE and the NYSE Euronext Lisbon, increase in liquidity, dispersed regulatory control and acceleration of the synergies created by the Transaction. The Companies expect the Merger of Shares to occur by the end of the first quarter of 2015.

The Companies will keep their shareholders and the market in general informed of any relevant subsequent events related to the topics described in this Material Fact.
