Harris Computer Systems Corp has stepped up its campaign to persuade Concurrent Computer Corp, and on Friday, the Fort Lauderdale, Florida company improved its offer to one Harris Computer share for every 16 Concurrent, again being rebuffed on Sunday. Harris says it does not currently plan a hostile tender offer for the Oceanport, New Jersey company. Harris Computer also disputes Concurrent’s public utterances, saying that it was not true that Concurrent had tried to acquire Harris, and that the implication that Harris Computer was attempting to acquire Concurrent’s Maxion technology was false. Harris says it has no plans to adopt the Maxion architecture, but does plan to incorporate Concurrent’s customer-specific software into its Night Hawk architecture, and adds that it believes significant savings can be realised in the combined research and development.
