Additional Information Regarding the Industrial Alliance between Oi and Portugal Telecom

RIO DE JANEIRO, Oct. 25, 2013 /PRNewswire/ -- Oi S.A. ("Oi"), in compliance with requests made by the Brazilian Securities Commission, hereby reiterates and clarifies to its shareholders and to the market certain information related to the transactions provided in the Memorandum of Understanding for the merger of the activities of Oi and Portugal Telecom SGPS S.A. ("Portugal Telecom") (the "Transactions"), announced in the Fato Relevante dated October 2, 2013.

As described in the Fato Relevante, Telemar Participacoes S.A. ("TmarPart") and holding companies that hold shares of TmarPart, AG Telecom Participacoes S.A. ("AG") and LF Tel S.A. ("LF"), will be capitalized with the resources needed to fully repay their indebtedness, in a manner such that, other that the shares of Oi, the net assets represented by the other assets and liabilities of these companies corresponds to zero or slightly more than zero. The increase in the capital of AG and LF, to be contributed directly or indirectly by Portugal Telecom, will be approximately R$2.25 billion. AG and LF, in turn, will contribute approximately R$3.1 billion to the capital of TmarPart, in the proportion of 50.0% each.

These capital increases will be made through the subscription by Portugal Telecom of debentures convertible into shares of AG and LF, followed by the subscription by AG and LF of debentures convertible into shares of TmarPart, providing the funds necessary to settle the debt of each of these companies, which amounts to an aggregate of approximately R$4.5 billion, consisting of R$650 million of debt of each of AG and LF, and approximately R$3.1 billion of debt of TmarPart.

After these capital increases, the corporate structure of these companies will be simplified through corporate reorganization transactions. Any goodwill registered by these companies as a result of these transactions will not be considered for the purposes of determining the exchange ratio applicable to the mergers (including goodwill registered by TmarPart with respect to the acquisition of Brasil Telecom S.A.), given that, as previously disclosed, the exchange ratios for these mergers were based on the Oi shares held directly or indirectly by the companies involved in the Transactions (assuming that they will be capitalized with the resources (cash or very liquid assets) needed to settle their indebtedness in full).

As a result, the goodwill registered in the companies whose corporate structure will be simplified (including Bratel Brasil S.A.), which includes not only the goodwill related to the acquisition of Brasil Telecom S.A. mentioned above, but also other goodwill created by the controlling shareholders of Oi that may be transferred to Oi for the benefit of all of Oi's shareholders, will not result in any dilution to the non-controlling shareholders of these companies. The controlling shareholders of Oi will not use the right provided in article 7 of CVM Instruction No. 319/99, therefore the goodwill will be used to benefit all the shareholders. When applicable, the companies involved in the Transactions will comply with article 6 of CVM Instruction No. 319/99.

Finally, Oi filed, via CVM's IPE System, on this date, a copy of the Memorandum of Understanding dated October 1, 2013 in relation to the Transactions. It is important to note that the Memorandum of Understanding is subject to the satisfaction of conditions, including the negotiation and execution of definitive agreements and the definition of a final structure for the conclusion of the action that are part of the Transactions.
