Announcement  | Lisbon  | 16 July 2014

PT and Oi reaffirm their support for the business combination

Portugal Telecom, SGPS, S.A. (“PT”) and Oi S.A. (“Oi”) announce that they remain committed to the full completion of their business combination and have signed a new Memorandum of Understanding (“MOU”).

The MOU has been signed following the non-repayment today by Rio Forte Investments SA (“Rioforte”), a company of Grupo Espírito Santo (“GES”), of the Euro 847 million matured portion of the outstanding Euro 897 million treasury applications (“Rioforte debt”) subscribed to by the PT group. The Rioforte debt is currently held in subsidiaries that were contributed to Oi on 5 May 2014 in the context of the business combination announced on 2 October 2013.

·                      Subject to agreement of definitive documentation and approval by the General Shareholders Meeting of PT, which will occur by 8 September 2014, the Board of Directors of Oi and Comissão de Valores Mobiliários, PT and Oi agreed that:

·                       PT will receive Rioforte debt from Oi in exchange for consideration of 474,348,720 Oi ON shares plus 948,697,440 PN shares (the “Oi Call Shares”);

·                       PT will be granted an American-type call (“Call”) to repurchase the Oi Call Shares (strike prices of R$1.8529 ON and R$2.0104 PN), which will be adjusted by the Brazilian CDI rate plus 1.5% per year;

·                       The Call on the Oi Call Shares will have a 6-year maturity, and the percentage of the Oi Call Shares that PT has the right to call will be reduced by 10% at the end of the 1st year and by 18% per year thereafter; and

·                       The MoU will remain in force until the earlier of: (1) execution of the definitive documentation and (2) 8 September 2014.

·                      The proposed structure is aimed at accomplishing the following objectives:

·                       To provide the time that may be necessary to minimise the loss in the value of the Rioforte debt.

·                       To allow for the completion of the business combination as soon as possible based on the agreed consideration for PT Shareholders (3.64 shares of CorpCo per share of PT), split into two components:

·                  2.10 shares of CorpCo per each PT share to be received upon implementation of the merger between PT and CorpCo corresponding to an ownership interest in CorpCo of 25.6% adjusted for the treasury shares resulting from this proposed structure; and

·                  An interest in the Rioforte debt and the Call (with an underlying number of Oi shares equivalent to 1.54 CorpCo shares per PT share), the value of which depends on recovery on the Rioforte debt and on the value of the underlying Oi shares.

·                      PT, in coordination with Oi, will pursue its legal and procedural options against Rioforte and relevant related parties to the full extent of the law, to secure repayment of the Rioforte debt. Oi will, at the request of PT, provide all required support and take all required actions in this regard.

PT and Oi remain committed to completing the remaining steps of the business combination, which include the merger of shares of Oi into CorpCo and the migration to the “Novo Mercado”. Furthermore PT emphasizes that any potential delay in the timetable of the merger of PT and CorpCo does not need to have any impact on the objective of the migration to the “Novo Mercado”.
