Valeant Pharmaceuticals International Announces
Proposed Private Offering of Senior Notes
COSTA MESA, CA, November 25, 2003 – Valeant Pharmaceuticals International (NYSE: VRX) announced today its intention to offer, subject to market and other conditions, approximately $275 million in principal amount of Senior Notes due 2011. Ribapharm Inc., a wholly owned subsidiary of Valeant Pharmaceuticals, will also be an obligor with respect to the notes, jointly and severally with Valeant Pharmaceuticals, until certain events occur.
Valeant Pharmaceuticals intends to use a portion of the net proceeds of the offering to retire, pursuant to privately negotiated transactions, open market purchases, a tender offer or otherwise, all of the company’s outstanding 6 1/2 percent Convertible Subordinated Notes due 2008 that are not retired with the net proceeds of the company’s recently issued Convertible Subordinated Notes due 2010 and 2013. Any remaining proceeds not used to retire the 6 1/2 percent Convertible Notes will be used for general corporate purposes, including potential acquisitions.
On November 24, 2003, the company retired $139.6 million of the 6 1/2 percent Convertible Subordinated Notes through open market purchases. There are approximately $326 million in principal amount of the 6 1/2 percent Convertible Subordinated Notes outstanding.
