Further to Benmc comments. There is no voting as such. The Sundance board will make a recommendation but each individual shareholder decides whether to accept the offer or not (ie. to sell or keep their shares).
The offer may be conditional and there are rules governing compulsory acquisitions if the bidder acquires more than 90% of the company's shares.
