ALLERGAN TO OFFER CONVERTIBLE SENIOR NOTES DUE 2026
AND SENIOR NOTES DUE 2016

(IRVINE, Calif., April 5, 2006) — Allergan, Inc. (NYSE: AGN) today announced the proposed concurrent private placements of $700 million aggregate principal amount of Convertible Senior Notes due 2026 (or $750 million aggregate principal amount if the initial purchasers exercise their expected over-allotment option in full), and $800 million aggregate principal amount of Senior Notes due 2016. Allergan estimates that the net proceeds from these offerings will be approximately $1.48 billion after deducting discounts, commissions and estimated expenses (or $1.53 billion if the initial purchasers exercise their expected over-allotment option in full). The Convertible Senior Notes are being offered in a private placement to qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933 and the Senior Notes are being offered in a private placement to qualified institutional buyers and non-U.S. persons pursuant to Rule 144A and Regulation S under the Securities Act of 1933.

The interest rate and other terms of the Convertible Senior Notes and Senior Notes are to be determined by negotiations between Allergan and the initial purchasers of the notes. Allergan also expects to grant the initial purchasers an option to purchase additional Convertible Senior Notes to cover over-allotments.

Allergan expects to use the net proceeds from the offerings of the Convertible Senior Notes and the Senior Notes, along with cash from its balance sheet, to repay the approximately $825.0 million outstanding under the bridge credit facility it entered into in connection with its acquisition of Inamed Corporation on March 23, 2006, to pay transaction expenses from the Inamed acquisition, to redeem its currently outstanding Zero Coupon Senior Convertible Notes due 2022 and to repurchase approximately $257 million worth of shares of its common stock (or $306 million if the initial purchasers exercise their over-allotment option in full), some of which may be purchased contemporaneously with the closing of the sale of the Convertible Senior Notes, including through private block trades with one or more of the initial purchasers and/or their affiliates.

Any offers of the securities will be made only by means of a private offering memorandum. The Senior Notes, the Convertible Senior Notes and the shares of Allergan common stock issuable upon conversion of the Convertible Senior Notes have not been,
