In the case of 5% or greater shareholders, we have not deemed such shareholders to be affiliates unless there are facts and circumstances which would indicate that such shareholders exercise any control over the Registrant, or unless they hold 10% or more of the Registrant’s share capital outstanding. This determination is not necessarily a conclusive determination for other purposes.
