VALEANT PHARMACEUTICALS TO ACQUIRE
PHARMASWISS S.A.

     Mississauga, ON, Canada and Zug, Switzerland — February 1, 2011 — Valeant Pharmaceuticals International, Inc. (NYSE: VRX) (TSX: VRX) and PharmaSwiss S.A. announced today that they have signed a binding agreement for Valeant to acquire PharmaSwiss, a privately-owned branded generics and over-the-counter (OTC) pharmaceutical company based in Zug, Switzerland for €350 million. Upon closing, PharmaSwiss is expected to have approximately €38 million cash on hand and no debt. Up to an additional €30 million may be payable to certain stockholders of PharmaSwiss based upon achievement of certain milestones.

     PharmaSwiss has a broad product portfolio in seven therapeutic areas and operations in nineteen countries throughout Central and Eastern Europe, including Poland, Hungary, the Czech Republic and Serbia. The company also has operations in Greece and Israel. In addition, PharmaSwiss is an existing partner to several large pharmaceutical and biotech companies offering regional expertise in such functions as regulatory, compliance, sales, marketing and distribution. PharmaSwiss had annual revenues of approximately €180 million in 2010 and has been growing at approximately 20% per year over the past 5 years.

     The senior management team of PharmaSwiss will remain with Valeant, including both the founder-partners, as well as Pavel Mirovsky, chief executive officer of PharmaSwiss. All of them are expected to continue in their leadership roles, working closely with the Valeant Europe team. Mr. Mirovsky will report directly to Valeant’s chief executive officer, J. Michael Pearson. Over time, it is anticipated the Valeant business in Central Europe will be combined under the PharmaSwiss corporate structure, based in Zug, Switzerland.

     The transaction, which is subject to customary closing conditions, including certain regulatory approvals, is expected to close in the first or second quarter of 2011 and to be immediately accretive to Valeant. After synergies, it is expected that the operating income as a percentage of revenue of the combined Central and Eastern European business will be similar to that of Valeant’s historical branded generic European business.

     “This acquisition of PharmaSwiss solidifies our position as a leading pharmaceutical company in Central and Eastern Europe,” said Mr. Pearson. “PharmaSwiss has an attractive partnering strategy as well as a complementary branded generics and OTC product portfolio that will strengthen our presence in the region.”

     “I am delighted that PharmaSwiss will be joining Valeant,” commented Dr. Pavel Mirovsky. “Valeant’s additional resources, professional approach, focused pipeline and strong commitment to supporting all three legs of the PharmaSwiss business model (Representation of multinationals, Licensing from specialty pharma, and Own Brands), will enable us to build up our winning strategy of serving partners. Valeant Europe’s strong presence in Poland, the region’s largest market, fills an important gap and should contribute to transaction synergies. The message we want to send to our employees, business partners and other stakeholders is one of continuity and commitment to growth.”
