Forward-Looking Statements 

In this press release, the statements regarding product development, market potential, expected growth, the statements by Mr. Pyott as well as the outlook for Allergan's earnings per share and revenue forecasts, among other statements above, 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 a quarter's end and year's end. 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.

Any other statements in this press release that refer to Allergan's expected, estimated or anticipated future results are forward-looking statements. 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 litigations, 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, matters generally affecting the economy, such as changes in interest and currency exchange rates; international relations and the state of the economy worldwide 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 months ended March 30, 2007 and March 31, 2006 and with respect to anticipated results for the second quarter and full year of 2007. 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 prepared in accordance with accounting principles generally accepted in the United States.

In this press release, Allergan reported the non-GAAP financial measure "adjusted earnings" and related "adjusted diluted earnings per share." Allergan uses adjusted earnings to enhance the investor's overall understanding of the financial performance and prospects for the future of Allergan's core business activities. Adjusted 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 adjusted 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 adjusted earnings for evaluating management performance for compensation purposes.

Despite the importance of adjusted earnings in analyzing Allergan's underlying business, the budgeting and forecasting process and designing incentive compensation, adjusted earnings has no standardized meaning defined by GAAP. Therefore, adjusted 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, and certain acquisitions, including severance and facility transition costs associated with acquisitions;

* it does not reflect 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 resulting from certain matters we consider not to be indicative of our on-going operations; and

* other companies in our industry may calculate adjusted earnings differently than we do, which may limit its usefulness as a comparative measure.

Allergan compensates for these limitations by using adjusted earnings only to supplement net income (loss) 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 (loss) and cash flows determined under GAAP as compared to adjusted earnings, and to perform their own analysis, as appropriate.
