Item 5. Other Events.

     On July 1, 2002, Cytyc Corporation, a Delaware corporation ("Cytyc"),
issued a press release announcing that Digene Corporation, a Delaware
corporation ("Digene"), has terminated their definitive merger agreement. Under
the terms of the merger agreement, either of Cytyc or Digene was permitted to
terminate the merger agreement if the transaction had not been consummated on or
before June 28, 2002. As previously announced, the U.S. Federal Trade Commission
last week voted to seek to block Cytyc's proposed acquisition of Digene.

     The termination of the merger agreement also terminates Cytyc's previously
announced exchange offer for shares of Digene's common stock. All shares
deposited pursuant to the exchange offer with Cytyc's exchange agent, EquiServe
Trust Company, N.A., will be returned promptly.

     A copy of the press release of July 1, 2002 is filed herewith as
Exhibit 99.1.
