Forward-Looking Statements

In this press release, the statements regarding product development, market potential, expected growth, regulatory approvals, the statements by Mr. Pyott as well as Allergan's earnings per share, product net sales, revenue forecasts and any other statements that refer to Allergan's expected, estimated or anticipated future results, are forward-looking statements. 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 the end of the applicable reporting period. Therefore, Allergan will not report or comment on its progress during a current quarter except through public announcement. Any statement made by others with respect to progress during a current quarter cannot be attributed to Allergan.

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 the following: 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, tax 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 continued economic volatility, can materially affect Allergan's results. Therefore, the reader is cautioned not to rely on these forward-looking statements.

?GAAP? refers to financial information presented in accordance with generally accepted accounting principles in the United States.

This press release includes non-GAAP financial measures, as defined in Regulation G promulgated by the Securities and Exchange Commission, with respect to the three and twelve months ended December 31, 2010 and December 31, 2009 and with respect to anticipated results for the first quarter and full year of 2011. Allergan believes that its presentation of non-GAAP financial measures provides useful supplementary information to investors regarding its operational performance because it enhances an investor's overall understanding of the financial performance and prospects for the future of Allergan's core business activities by providing a basis for the comparison of results of core business operations between current, past and future periods. The presentation of historical non-GAAP financial measures is not meant to be considered in isolation from or as a substitute for results as reported under GAAP.

In this press release, Allergan reported the non-GAAP financial measures ?non-GAAP basic and diluted earnings per share attributable to Allergan, Inc. stockholders? and ?non-GAAP earnings attributable to Allergan, Inc.? and its subcomponents ?non-GAAP other revenues,? ?non-GAAP cost of sales,? ?non-GAAP selling, general and administrative expenses,? ?non-GAAP research and development expenses,? ?non-GAAP amortization of acquired intangible assets,? ?non-GAAP legal settlement,? ?non-GAAP intangible asset impairment and related costs,? ?non-GAAP restructuring charges,? ?non-GAAP operating income,? ?non-GAAP interest expense,? ?non-GAAP gain on investments, net,? ?non-GAAP other, net,? ?non-GAAP earnings before income taxes,? ?non-GAAP provision for income taxes,? and ?non-GAAP net earnings.? Allergan uses non-GAAP earnings to enhance the investor's overall understanding of the financial performance and prospects for the future of Allergan's core business activities. Non-GAAP earnings is one of the primary indicators management uses for planning and forecasting in future periods, including trending and analyzing the core operating performance of Allergan's business from period to period without the effect of the non-core business items indicated. Management uses non-GAAP earnings to prepare operating budgets and forecasts and to measure Allergan's performance against those budgets and forecasts on a corporate and segment level. Allergan also uses non-GAAP earnings for evaluating management performance for compensation purposes.

Despite the importance of non-GAAP earnings in analyzing Allergan's underlying business, the budgeting and forecasting process and designing incentive compensation, non-GAAP earnings has no standardized meaning defined by GAAP. Therefore, non-GAAP earnings has limitations as an analytical tool, and should not be considered in isolation, or as a substitute for analysis of Allergan's results as reported under GAAP. Some of these limitations are:

• it does not reflect cash expenditures, or future requirements, for expenditures relating to restructurings, legal settlements, and certain acquisitions, including severance and facility transition costs associated with acquisitions;
• it does not reflect asset impairment charges or gains or losses on the disposition of assets associated with restructuring and business exit activities;
• it does not reflect the tax benefit or tax expense associated with the items indicated;
• it does not reflect the impact on earnings of charges or income resulting from certain matters Allergan considers not to be indicative of its on-going operations; and
• other companies in Allergan's industry may calculate non-GAAP earnings differently than it does, which may limit its usefulness as a comparative measure.

Allergan compensates for these limitations by using non-GAAP earnings only to supplement net earnings on a basis prepared in conformance with GAAP in order to provide a more complete understanding of the factors and trends affecting its business. Allergan strongly encourages investors to consider both net earnings and cash flows determined under GAAP as compared to non-GAAP earnings, and to perform their own analysis, as appropriate.

In this press release, Allergan also reported sales performance using the non-GAAP financial measure of constant currency sales. Constant currency sales represent current period reported sales adjusted for the translation effect of changes in average foreign exchange rates between the current period and the corresponding period in the prior year. Allergan calculates the currency effect by comparing adjusted current period reported amounts, calculated using the monthly average foreign exchange rates for the corresponding period in the prior year, to the actual current period reported amounts. Management refers to growth rates at constant currency so that sales results can be viewed without the impact of changing foreign currency exchange rates, thereby facilitating period-to-period comparisons of Allergan's sales. Generally, when the dollar either strengthens or weakens against other currencies, the growth at constant currency rates will be higher or lower, respectively, than growth reported at actual exchange rates.

Reporting sales performance using constant currency sales has the limitation of excluding currency effects from the comparison of sales results over various periods, even though the effect of changing foreign currency exchange rates has an actual effect on Allergan's operating results. Investors should consider these effects in their overall analysis of Allergan's operating results.
