THE PURPOSE OF THIS AMENDMENT NO. 12 TO SCHEDULE 13D IS TO AMEND THE
OWNERSHIP REPORTS OF THE REPORTING PERSONS AND TO AMEND ITEM 4(PURPOSE OF
TRANSACTION), ITEM?6 (CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR
RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER) AND ITEM 7 (MATERIAL
TO BE FILED AS EXHIBITS). THE INFORMATION BELOW SUPPLEMENTS THE INFORMATION
PREVIOUSLY PROVIDED.

Item 4.     Purpose of Transaction

      Item 4 to Schedule 13D is amended, in pertinent part as follows:

	On April 30, 2010, ValueAct Capital Master Fund, L.P. ("ValueAct") and
Valeant Pharmaceuticals International (the "Issuer") entered into a Purchase
Agreement (the "Purchase Agreement") whereby ValueAct sold 2,637,545 million
shares of the Common Stock to the Issuer at $40.4116 per share in cash for an
aggregate price of $106,587,413.52.

	The sale of the Common Stock by ValueAct to the Issuer was subject to
customary conditions concerning accuracy of representations and warranties,
performance of obligations under the Purchase Agreement and a one-time
payment by ValueAct to the Issuer for reimbursement of certain costs and
expenses incurred by the Issuer related to this transaction, which amount was
netted from the purchase price at the Closing. The Purchase Agreement
contains several representations and warranties, which were made as of the
date of the Purchase Agreement and as of the closing, including the
following: (i) the parties are duly organized and validly existing; (ii) the
parties have the requisite power and authority to enter into the agreement
and perform their obligations thereunder; (iii) entry into the Purchase
Agreement will not violate either party?s organizational documents, conflict
with any agreement, indenture or instrument to which either entity is a
party, or result in a violation of any law, rule, regulation, order, judgment
or decree, except in the case of clause (ii) and (iii), for such conflicts
which would not, individually or in the aggregate, reasonably be expected to
have a material adverse effect on the ability of such party to perform its
obligations thereunder; and (iv) ValueAct has good and valid title to the
shares of Common Stock sold to the Issuer under the Purchase Agreement.

       A copy of the Purchase Agreement has been previously filed as Exhibit
99.1 to the Issuer?s Current Report on Form 8-K dated May 3, 2010 and is
incorporated by reference herein.

       Except as set forth in this Report and in connection with the Purchase
Agreement described above, the Reporting Persons have no plan or proposals
that relate to or would result in any of the transactions described in
subparagraphs (a) through (j) of Item 4 of Schedule 13D.? The Reporting
Persons may at any time reconsider and change their plans or proposals
relating to the foregoing.
