At least five in-house lawyers at Netscape Communications Corp. are leaving the company in the wake of last month’s merger with America Online Inc., but general counsel Roberta Katz will be sticking around — for now at least.

Up to 1,000 employees from both companies are expected to lose their jobs under a restructuring plan announced March 25. That means a major shake-up for Netscape’s 18-person legal department, which is being integrated with the 30-lawyer staff at Dulles, Va.-based AOL, headed by GC George Vradenburg III. It was not known Friday if any AOL legal positions have been or will be cut as a result of the merger.
