They had originally rejected the offer, which values the company at around £50m. However, they said there was a "significantly increased likelihood" that Mayfair would achieve the 75% holding it needed for the company's shares to be cancelled from trading on AIM following the closing date of the offer on October 16th. They advised shareholders to accept the deal, warning the value of any outstanding Timeweave stock would be badly hit if trading was cancelled.MM
