• Allergan's adjusted diluted earnings per share from continuing operations were $0.76 in the fourth quarter of 2008, compared to adjusted diluted earnings per share of $0.60 in the fourth quarter of 2007, a 26.7 percent year-over-year increase.

Product Sales

For the quarter ended December 31, 2008:

• Allergan's total product net sales were $1,041.0 million. Total product net sales decreased 3.2 percent as compared to total product net sales in the fourth quarter of 2007. On a constant currency basis, total product net sales increased 1.6 percent compared to total product net sales in the fourth quarter of 2007.
  • Total specialty pharmaceuticals net sales decreased 1.4 percent as compared to total specialty pharmaceuticals net sales in the fourth quarter of 2007. On a constant currency basis, total specialty pharmaceuticals net sales increased 3.3 percent compared to total specialty pharmaceuticals net sales in the fourth quarter of 2007.
  • Core medical devices net sales decreased 9.6 percent, or 4.8 percent at constant currency, compared to core medical devices net sales in the fourth quarter of 2007.

"Allergan continued to demonstrate an ability to apply discipline and execution in our core specialty businesses despite the challenging economic environment observed in the fourth quarter of 2008," said David E.I. Pyott, Allergan's Chairman of the Board and Chief Executive Officer. "Our goal is to continue to focus on enhancing efficiencies and strengthening our position within our core specialty markets throughout 2009, as we look forward to the anticipated approvals and launches of new growth drivers from our rich R&D pipeline, including the recently approved LATISSETM for enhanced eyelash prominence."

Based on internal information and assumptions, full year 2008 therapeutic sales accounted for approximately

50% of total BOTOX® (botulinum toxin type A) sales and grew at a rate of approximately 8% compared to

2007. Full year 2008 cosmetic sales accounted for approximately 50% of total BOTOX® sales and grew at a rate of approximately 8% compared to 2007.

Restructuring

In order to concentrate Allergan's resources during this recessionary period on customer-facing activities and on building the strength of its R&D pipeline, while continuing to deliver on its earnings goals, Allergan conducted a worldwide review of its operations to improve efficiency.  Furthermore, Allergan will focus its spending on programs and businesses that produce the highest returns.  Consequently, Allergan will lay off approximately 460 employees, or approximately 5 percent of its global headcount, primarily in the United States and Europe.

The majority of the employees affected by the restructuring are in two areas: (1) U.S. urology sales and marketing personnel as a result of the Company's decision to focus on the urology specialty and to seek a partner to promote SANCTURA XR® to general practitioners, and (2) marketing personnel in the United States and Europe as Allergan adjusts its back-office structures to the reduced short-term sales outlook for some businesses.  With the exception of the U.S. urology sales force and some low productivity sales territories in Europe, no other sales force positions are affected.  Modest reductions are being made in other functions as Allergan re-engineers its processes and increases productivity.

Further, Allergan has reviewed its stock option-related cost structure.  Allergan's 2008 full-round employee stock option grant took place in February 2008 with a strike price of $64.47 versus a current stock price of approximately $40.  While Allergan does not intend to institute a stock option exchange or repricing program, the Company's Board of Directors has decided to accelerate the vesting and remove certain stock option expiration features for all employees holding the 2008 full-round employee stock options and to modify certain stock option expiration features for other stock options held by employees impacted by the restructuring.   Allergan will incur a one-time charge in the first quarter of 2009 associated with these stock option grant modifications.

Allergan currently estimates that it will incur total non-recurring pre-tax charges of between $110 million and $117 million in connection with the restructuring, of which only $40 million to $45 million will be a cash charge.  The remainder will be a non-cash accounting-related charge associated with the acceleration of previously unrecognized share-based compensation costs and any additional estimated costs associated with the modification of stock option grants as discussed above and certain other non-cash accounting adjustments.

These charges will be incurred beginning in the first quarter of 2009 and are expected to continue up through and including the fourth quarter of 2009.  The realized expense savings from the restructuring are expected to exceed the cash charges in less than one year.

Product and Pipeline Update

During the fourth quarter of 2008:

• On October 15, 2008, Allergan and Clinique, the #1 prestige cosmetics brand in the United States, announced the nationwide availability of CLINIQUE MEDICAL. This new skin care line is scientifically designed and clinically proven to complement select in-office cosmetic procedures and is available only through skin care physicians' offices.
• Allergan completed the initial analysis of data from its Phase III studies of POSURDEX® for macular edema associated with retinal vein occlusion (RVO).The data demonstrated that patients receiving either the 350 microgram or the 700 microgram dose of POSURDEX® had a statistically significant increase in vision based on a 3-line or better improvement in visual acuity compared to a sham treatment.In addition, both doses of POSURDEX® were well tolerated in the studies. Less than 7% of patients receiving 700 or 350 micrograms of POSURDEX® experienced an elevation of intraocular pressure (IOP) greater than 35 mm Hg at any time during the 6 month study, and at 6 months less than 1% of patients had an IOP above 25 mm Hg. In the fourth quarter, Allergan completed filing the last module of its new drug application (NDA) with the U.S. Food and Drug Administration (FDA) for the approval of POSURDEX® to treat macular edema associated with RVO. POSURDEX® is a novel formulation of dexamethasone in Allergan's proprietary, sustained-release drug delivery system that can be used to locally administer medications to the retina. Brimonidine in this drug delivery system is also currently being investigated as a treatment for retinal disease in Phase II clinical trials.
• Allergan invested in BAROnova, Inc.'s Series B financing to further advance the development of BAROnova's new technology designed to meet an unmet need in obesity intervention. BAROnova's non-surgical, non-pharmacologic TransPyloric Shuttle (TPS) weight-loss technology uses a revolutionary mechanical approach that helps the patient's stomach to fill up more quickly and to stay full longer, triggering the body's natural intake-reduction processes.
• Allergan entered into an exclusive discovery and license agreement with Polyphor Ltd whereby Allergan obtained the rights to discover, develop and commercialize compounds for the treatment of eye diseases.
• On October 29, 2008, Allergan announced that Allergan and Spectrum Pharmaceuticals, Inc. signed an exclusive collaboration for the development and commercialization of apaziquone, an antineoplastic agent currently being investigated for the treatment of non-muscle invasive bladder cancer.
• On December 26, 2008, Allergan announced FDA approval of LATISSETM (bimatoprost ophthalmic solution) 0.03%, a novel treatment for eyelash hypotrichosis or inadequate eyelashes. LATISSETM is the first and only science-based treatment approved by the FDA to enhance eyelash prominence as measured by increases in length, thickness and darkness of eyelashes.

Following the end of the fourth quarter of 2008:

• GlaxoSmithKline received approval of BOTOX® (botulinum toxin type A) for the treatment of glabellar lines in Japan. They plan to launch in the first quarter of 2009.

Because forecasts are inherently estimates that cannot be made with precision, Allergan's performance at times differs materially from its estimates and targets, and Allergan often does not know what the actual results will be until after a quarter's end and year's end.

All forward-looking statements in this press release reflect Allergan's current analysis of existing trends and information and represent Allergan's judgment only as of the date of this press release. Actual results may differ materially from current expectations based on a number of factors affecting Allergan's businesses, including, among other things, changing competitive, market and regulatory conditions; the timing and uncertainty of the results of both the research and development and regulatory processes; domestic and foreign health care and cost containment reforms, including government pricing and reimbursement policies; technological advances and patents obtained by competitors; the performance, including the approval, introduction, and consumer and physician acceptance of new products and the continuing acceptance of currently marketed products; the effectiveness of advertising and other promotional campaigns; the timely and successful implementation of strategic initiatives; the results of any pending or future litigation, investigations or claims; the uncertainty associated with the identification of and successful consummation and execution of external corporate development initiatives and strategic partnering transactions; and Allergan's ability to obtain and successfully maintain a sufficient supply of products to meet market

demand in a timely manner. In addition, U.S. and international economic conditions, including higher unemployment, financial hardship, consumer confidence and debt levels, taxation, changes in interest and currency exchange rates, international relations, capital and credit availability, the status of financial markets and institutions, as well as the general impact of the current economic crisis, can materially affect Allergan's results.
