(a)     joint advertising and selling activities, intended to be carried out in future by Steeline members (including the operation of an online store) and

(b)     collective bargaining conduct, which involves Steeline negotiating and entering into supply arrangements regarding the terms of supply of various products to its members, including steel sheet and coil.
