BARR SAYS SUIT FILED BY INVAMED IS WITHOUT MERIT


POMONA, NY, FEBRUARY 25, 1998, -- Barr Laboratories, Inc. -- (NYSE-BRL) today
issued the following response to a lawsuit filed by Invamed, Inc. that named
Barr as a defendant in a lawsuit regarding access to the raw material source for
generic warfarin sodium anticoagulant.

                                      - - -

Barr believes that the suit filed against it by Invamed is without merit. It is
common in the pharmaceutical industry for companies to have exclusivity
agreements with raw material providers. Barr has such an exclusive agreement
with the provider of warfarin sodium raw material.

Barr made a significant investment in identifying and qualifying a raw material
source for its warfarin sodium product. In exchange for this investment, the
Company entered into an agreement in September 1995 for exclusive production
quantities of the raw material. The Company believes that this is a valid
agreement, and that the suit is groundless.

Barr believes that this suit will have no impact on its ability to receive the
quantities of raw material necessary to meet market demand for its generic
warfarin sodium product.

Barr Laboratories, Inc. is engaged in the development, manufacture and marketing
of generic and proprietary pharmaceuticals.
