ITEM 1. CHANGES IN CONTROL OF REGISTRANT.

         On April 16, 2001 (the "Notice Date"), Allergan, Inc. ("Allergan")
delivered notice to Allergan Specialty Therapeutics, Inc. (the "Registrant") of
Allergan's exercise of its option pursuant to the Registrant's Restated
Certificate of Incorporation (the "Restated Certificate") to purchase all of the
3,272,690 issued and outstanding shares of Class A Common Stock of the
Registrant (the "Purchase Option"). Allergan further notified the Registrant
that, as determined in accordance with the Restated Certificate, the aggregate
purchase price for such shares of the Registrant's Class A Common Stock will be
$71,007,000 (the "Purchase Price"), or $21.70 per share of outstanding Class A
Common Stock. The closing of the purchase of all Class A Common Stock is
scheduled to occur on April 20, 2001 (the "Closing Date").

         Allergan will pay this Purchase Price in cash. On or before the Closing
Date, Allergan will deposit the full amount of the Purchase Price with EquiServe
N.A. (the "Payment Agent"). Funds deposited with the Payment Agent will be
delivered in trust for the benefit of the holders of the Registrant's Class A
Common Stock, and Allergan will provide the Payment Agent with irrevocable
instructions to pay, on or after the Closing Date, the Purchase Price for the
shares of Class A Common Stock to the holders of record thereof determined as of
the Closing Date. Payment for shares of the Registrant's Class A Common Stock
will be mailed to each holder at the address set forth in the Registrant's
records or at the address provided by each holder or, if no address is set forth
in the Registrant's records for a holder or provided by such holder, to such
holder at the address of the Registrant. As soon as practicable upon Allergan's
request, the Registrant will provide, or will cause its transfer agent to
provide, to Allergan or to the Payment Agent, free of charge, a complete list of
the record holders of Class A Common Stock, as of a specified date, including
the number of shares of Class A Common Stock held of record and the address of
each record holder as set forth in the records of the Registrant's transfer
agent.

         Transfer of title to all of the issued and outstanding shares of Class
A Common Stock will be deemed to occur automatically on the Closing Date, and,
thereafter, the Registrant will be entitled to treat Allergan as the sole holder
of all of the issued and outstanding shares of its Class A Common Stock,
notwithstanding the failure of any holder of Class A Common Stock to tender the
certificates representing such shares to the Payment Agent, whether or not such
tender is required or requested by the Payment Agent. The Registrant will
instruct its transfer agent not to accept any shares of Class A Common Stock for
transfer on and after the Closing Date, other than as necessary to process any
trade or transfer effected prior to the Closing Date.

         EquiServe N.A. has been retained by Allergan to serve as the Payment
Agent. Letters of transmittal, together with instructions relating thereto, are
expected to be provided promptly following the Closing Date to the Registrant's
former stockholders so that such stockholders may receive their respective pro
rata shares of the Purchase Price.

         Allergan has advised the Registrant that Allergan will fund the
purchase of all outstanding shares of Class A Common Stock from cash reflected
on Allergan's balance sheet.

         One exhibit to the Registrant's Annual Report on Form 10-K for the
fiscal year ended December 31, 1998 is incorporated herein by reference. Copies
