Werner Koepf, most recently executive chairman of Compaq Computer in Europe, the Middle East and Africa, has been appointed as a non-executive director of both Marconi Corporation and Marconi plc. The above appointments are effective immediately. As previously announced, Derek Bonham, who joined the Board in April 2001 and became interim chairman of Marconi plc in September 2001, is to stand down from the chairman's role. Derek will remain on the board as a non-executive director through the completion of Marconi's financial restructuring. Allen Thomas, who was appointed a non-executive director of Marconi in May 2002, has been appointed chairman of the remuneration committee. Commenting on the new appointments, Derek Bonham said: "Marconi has attracted a number of very high calibre and exceptional individuals with solid business track records to join and support the Board. These appointments represent a significant further milestone in restoring the company to health. "John Devaney brings a wealth of management experience gained in the international industrial sector that equips him well to support the existing management team to deliver the company's financial restructuring and for the years beyond. Kent Atkinson brings a working lifetime of international business experience in both line management and finance functions from one of the UK's leading banks. He was one of the key players in the bank's substantial growth during the 1990s and is an experienced non-executive and audit committee chairman. Werner Koepf brings a broad range of experience gained with a number of the world's technology leaders. These appointments add significant new strength and energy to the Marconi board. "The Board believes my remaining through to the successful completion of the financial restructuring will provide continuity and I am pleased to remain in the short term." John Devaney said: "The actions taken by the Marconi management team have gone a long way towards restoring the strong underlying business which, coupled with a repaired balance sheet, will enable the Company to weather the current difficult trading conditions in the communications equipment market, and to prosper long term. I am pleased to be part of a strong management team and believe my experience and support will help the new Board to return the business to full financial and operational health. I welcome the opportunity to take part in the revival of a great Company." Marconi is continuing its search for an additional non-executive director to add specific knowledge of the US telecommunications and technology market to further round out the considerable industry experience across the Board. Sir Alan Rudge and Hon Raymond G H Seitz, both non-executive directors of GEC plc and Marconi plc since 1997, have announced their intentions to resign from the Board immediately to make way for an orderly reconstruction of the Board. Sir William Castell and Nigel J Stapleton, who joined the Board of GEC plc in 1997 and Marconi plc in 1999, did not offer themselves for re-election to the Board at the company's annual general meeting on October 8, this year. Derek Bonham added: "I would like to express my gratitude to the outgoing non-executive directors who have persevered through a difficult period for the business, allowing us the time to secure new board members. The newly constructed board will help the business look to the future." ENDS/...
