Allergan and Alcon Reach Agreement on Brimonidine 0.15% Patent Litigation.

IRVINE, Calif. -- Allergan, Inc. (NYSE:AGN) announced today that Allergan and Alcon, Inc. (NYSE:ACL) have settled Allergan's patent infringement lawsuit in the United States District Court for the District of Delaware contending that Alcon's proposed brimonidine 0.15% product infringes two brimonidine-related patents owned by Allergan.

Pursuant to the settlement:

    1.  Alcon has agreed to a license beginning on September 30, 2009,
        in the United States under both patents at issue in the
        Delaware lawsuit;

    2.  Alcon will not sell, offer for sale or distribute its
        brimonidine 0.15% product until September 30, 2009, or earlier
        if certain market conditions occur, the primary condition
        being a trigger based generally on the extent to which
        prescriptions of ALPHAGAN(R) P 0.15% have been converted to
        other brimonidine-containing products (including ALPHAGAN(R)
        P 0.1% and COMBIGAN(TM)) marketed by Allergan.

    3.  Upon market entry of Alcon's 0.15% brimonidine product, Alcon
        will pay Allergan royalties on the sale of its product in the
        United States.

"We are pleased with this settlement and the delayed-entry license taken by Alcon, which respects our intellectual property portfolio," said David E.I. Pyott, Allergan's Chairman of the Board and Chief Executive Officer. "This delayed-entry license, which we are confident will not commence until September 30, 2009, is in line with Allergan's long-term strategy for our overall brimonidine franchise."

Additionally, Allergan has dismissed a separate patent infringement lawsuit filed by Allergan against Alcon in the United States District Court for the District of California related to self-preserved ophthalmic antibiotics.

Allergan's ALPHAGAN(R) franchise has been a leading therapy for reducing intraocular pressure (IOP) in patients safely and effectively for more than five years. ALPHAGAN(R), ALPHAGAN(R) P 0.1% and ALPHAGAN(R) P 0.15% are indicated for lowering IOP in patients with open-angle glaucoma or ocular hypertension.
