("Prime") approved a Plan of Arrangement to accept Homestake's offer to acquire the 49.4% of Prime it did not already own. Under the Plan of Arrangement, for each Prime Common Share outstanding (other than Prime Common Shares held by Homestake and its wholly owned subsidiaries), Prime shareholders had the option of receiving 0.74 of a Homestake Mining Company Common Share or 0.74 of a Homestake Canada Inc. Exchangeable Share ("HCI Exchangeable Share"). Each HCI Exchangeable Share is exchangeable for one share of Homestake Mining Company Common Stock at any time at the option of the holder and has essentially the same voting, dividend (payable in Canadian dollars), and other rights as one share of Homestake Common Stock. The Special Voting Stock referred to above was issued to Montreal Trust Company of Canada, in trust for the holders of the HCI Exchangeable Shares, and provides the mechanism for holders of HCI Exchangeable Shares to receive voting rights in Homestake Mining Company. On December 3, 1998 Homestake announced it had completed the acquisition of the 49.4% of Prime it did not already own. As a result of this transaction, Homestake owns 100% of Prime through Homestake's wholly owned subsidiary, Homestake Canada Inc.
