1. Viroserve Ltd (Viroserve) has recently acquired 48% of Aztec Ltd (Aztec) following a partial takeover bid. Viroserve would like to replace the existing directors of Aztec but the board refuses to call a meeting. Advise ViroserveLtd.
2. Suppose a meeting is eventually called and resolutions put to dismiss the existing directors. On the show of hands, Viroserve is outvoted. When Aztec calls for a poll, however, the Chair refuses the request and continues with themeeting.

Discuss Viroserve's rights in this matter.
