ITEM 5. OTHER EVENTS AND REGULATION FD DISCLOSURE.

Genentech, Inc. made the following statements, among others, with respect to
Xolair(R) (or E25) in its webcast conference call held on January 18, 2001, to
discuss its fourth quarter results. Genentech feels that it remains on track for
a summer FDA approval and launch. Genentech is focused on ensuring that it
supplies the FDA with thorough and complete information on the non-clinical
studies of Xolair, as well as an update of the new platelet monitoring
information from its ALTO study (a 24-week safety study in patients with
difficult to treat asthma) so as to assure the best possible product labeling.
Genentech anticipates supplying the full set of information to the FDA in late
March. Genentech noted that it was possible that the time needed for it to
supply the information to the FDA and discuss the labeling for Xolair could push
the launch into the fall of 2001. However, Genentech said it has received no
feedback from FDA to suggest there will be any delay.
