Informatics is the subject of a proxy campaign.

Sterling Software of Dallas said it will try to solicit enough proxy votes by shareholders of the Woodland Hills software company to replace Walter F. Bauer, Informatics General’s chairman, with its own chairman, Samuel E. Wyly. The announcement was made after Informatics rejected Sterling’s sweetened $26-a-share takeover bid. Sterling also said it will use proxies to try to defeat the anti-takeover measures that Informatics is proposing for its May 9 shareholders meeting. Sterling owns 9.3% of Informatics and has already filed suit to get a shareholder list.
