Javier de Paz and Manuel Pizarro, new members of Telefónica’s board

JULIO LINARES APPOINTED COO OF TELEFÓNICA

• Guillermo Ansaldo will head Telefónica España

        Madrid, 19 December 2007.- At its ordinary meeting today, Telefónica’s board, with the approval of the Nominating, Compensation and Corporate Governance Committee, has named Julio Linares, General Manager for Coordination, Business Development and Synergies, as the company’s new Chief Operating Officer. It also decided to appoint Guillermo Ansaldo as General Manager of Telefónica España. Mr Ansaldo will replace Antonio Viana-Baptista, who leaves the Company citing personal reasons.

        Meanwhile, Manuel Pizarro and Javier de Paz will replace Enrique Used and Maximino Carpio as members of Telefónica’s board of directors. Both Manuel Pizarro, Javier de Paz and Alfonso Ferrari will join as well the Executive Commission of the Company’s board of directors.

        The appointment of a new COO at Telefónica implies changes to the organisational structure, which in any event still supports a regional focus aimed at becoming more customer-oriented and leveraging economies of scale.

        From now, the three regional business divisions, Spain, Europe and Latin America, will report to the new COO, Julio Linares. Until now they had reported directly to the Company’s Executive Chairman and CEO, César Alierta. Guillermo Ansaldo will take Antonio Viana-Baptista’s place at the helm of Telefónica España, with Belén Amatriaín as the Company’s CEO and number two. Matthew Key will oversee Europe and José María Alvarez-Pallete will continue to lead Telefónica Latinoamérica. All three general divisions will continue to manage all the fixed and mobile businesses in their respective regions in an integrated way.

        Also reporting to Telefónica’s new COO will be four support units: Operations (Alfonso Alonso); Strategy, Innovation and Business Development (Sohail Qadri); Planning, Budgeting and Monitoring (Laura Abasolo); and Human Resources (Óscar Maraver).

Therefore, reporting directly to Telefónica’s Executive Chairman and CEO will be COO Julio Linares; the General Manager of Finance and Corporate Development, Santiago Fernández Valbuena; head of the Legal and Board Secretariat (Ramiro Sánchez de Lerín) and the head of the Technical Secretariat to the Chairman’s Office (Luis Abril). In the new chain of responsibilities, Internal Auditing will report to the Finance and Corporate Development unit, which will also act as Controller (Ezequiel Nieto).

        Antonio Viana-Baptista, until now the General Manager of Telefónica España, is leaving the company on his own accord, citing personal reasons. Mr Viana-Baptista, a longstanding executive at Telefónica, has spent the last nine years –eight of them also as member of the Board of Director- achieving huge success in Latin America, overseeing the global mobile division and, lastly, at Telefónica España. The company wishes to thank Antonio Viana-Baptista for his dedication and achievements over these years.

        The Telefónica board also agreed to add Manuel Pizarro and Javier de Paz as members. They will replace Enrique Used and Maximino Carpio, who will leave as well the committees they were part of. The Board recognized the intense work carried out by the outgoing directors and thanked them for the contribution and efforts in recent years.

        Lastly, Antonio Hornedo Muguiro will step down, for personal reasons, as deputy general secretary and secretary of the board of directors. He will be replaced by Mª Luz Medrano Aranguren.
