Allergan Proposes Increase in Authorized Shares.

IRVINE, Calif. -- Allergan, Inc. (NYSE:AGN) today announced that its Board of Directors has approved, subject to stockholder approval, an amendment to Allergan's restated Certificate of Incorporation that increases Allergan's authorized number of shares of common stock from 300 million to 500 million.

As of August 1, 2006, there were approximately 153,755,944 shares of common stock issued and outstanding and approximately 131,366,291 shares of common stock reserved for issuance pursuant to Allergan's outstanding 1.50% convertible senior notes due 2026 and Allergan's equity compensation plans.

Allergan intends to present the amendment to its stockholders for approval at a special meeting to be held on or about September 20, 2006. Stockholders of record at the close of business on August 14, 2006 will be entitled to notice of and to vote in person or by proxy at the special meeting.

Allergan's Board of Directors believes that the proposed increase in the number of authorized shares of common stock will enhance Allergan's flexibility in connection with a stock split or other corporate purposes. Other than increasing the number of authorized shares of common stock from 300 million to 500 million, the proposed amendment in no way changes Allergan's restated Certificate of Incorporation.

Allergan's Board of Directors has unanimously approved the proposed amendment and determined that it is in the best interests of Allergan and its stockholders. If approved by Allergan's stockholders, the amendment will become effective upon filing with the Delaware Secretary of State.
