The committee has however entered into negotiation with chairman David Murdock over the acquisition of the remaining 76 per cent of shares not already held by him or his family. The committee, set up by the board of directors when Murdock made his offer last month, is trying to agree a higher price and has also directed Goldman Sachs to contact other potential buyers.

Murdock has agreed to extend the November 6 deadline on his original offer by a week.
