ITEM 5. OTHER EVENTS AND REQUIRED FD DISCLOSURE.

      On May 25, 2004, the United States Court of Appeals for the Third Circuit
issued a decision reversing rulings by U.S. District Court Judge Harvey Bartle
III of the Eastern District of Pennsylvania that excluded certain evidence in
state court diet drug trials brought by class members who had exercised their
right to be an intermediate or back-end "opt out" from the nationwide diet drug
class action settlement. The complete Third Circuit decision is available at
http://www.ca3.uscourts.gov/opinarch/024582p.pdf. The foregoing description of
the Third Circuit decision does not purport to be complete and is qualified in
