BioMarin Pharmaceutical Inc. announced today several corrections to an article released by Bloomberg this morning. The article was based on a telephone interview with Jean-Jacques Bienaime, Chief Executive Officer of BioMarin, held on September 17, 2008.

Following is the correct information and is consistent with the information previously released publicly:

-- The Company expects that peak sales of Naglazyme could be $300 million world wide and that the Company expects to be "more than half way there" by next year. That is not intended as sales guidance for 2009.

-- The Company expects that peak sales of Kuvan could be $400 million in the U.S. and that, consistent with other orphan products, could take several years to reach that level. The Company can not predict the exact time to peak sales.

-- The Company has not provided any sales guidance for 2009 or subsequent years. As is the Company's standard practice, it expects that it will provide guidance for 2009 in connection with the release of its full year 2008 financial results in February of 2009.
