2020

SAN RAFAEL, Calif., Oct. 9, 2013 (GLOBE NEWSWIRE) -- BioMarin Pharmaceutical
Inc. (Nasdaq:BMRN) announced the pricing on October 8, 2013 of a total
offering of $680 million of its senior subordinated convertible notes
consisting of $340 million 0.75% Senior Subordinated Convertible Notes due
2018 (the "2018 Notes") and $340 million 1.50% Senior Subordinated Convertible
Notes due 2020 (the "2020 Notes" and together with the 2018 Notes, the
"Notes"). The Notes will be issued at a price equal to 100% of the principal
amount thereof.BioMarin intends to use the net proceeds from the offering for
general corporate purposes, including working capital and research and
development.In addition, BioMarin intends to use $27.03 million of the net
proceeds of the offering for the payment of the cost of the capped call
transactions described below. The offering of the Notes is expected to close
on October 15, 2013, subject to the satisfaction of customary closing
conditions.

BioMarin has granted the underwriters options to purchase up to an additional
$70 million aggregate principal amount of the Notes.The Notes will be
convertible, under certain circumstances, into cash, shares of BioMarin's
common stock or a combination thereof at BioMarin's election.The initial
conversion rate will be 10.6213 shares of common stock per $1,000 principal
amount of Notes (representing an initial conversion price of approximately
$94.15 per common share), subject to customary adjustments.The initial
conversion rate represents approximately a 40% premium to the last reported
sale price of the common stock on the NASDAQ Global Select Market on October
8, 2013.Interest on the Notes is payable semi-annually in arrears on April 15
and October 15 of each year, commencing on April 15, 2014. The 2018 Notes will
mature on October 15, 2018 and the 2020 Notes will mature on October 15, 2020,
in each case, unless earlier repurchased or converted in accordance with their
terms. Prior to July 15, 2018, in the case of the 2018 Notes, and July 15,
2020, in the case of the 2020 Notes, the Notes will be convertible only upon
the occurrence of certain events and during certain periods, and thereafter,
at any time until the second scheduled trading day immediately preceding the
applicable maturity date. BofA Merrill Lynch, Goldman, Sachs & Co., J.P.
Morgan and Morgan Stanley are acting as joint book-running managers for this
offering. Barclays is acting as co-manager.

In connection with the pricing of each of the 2018 Notes and the 2020 Notes,
BioMarin entered into privately-negotiated capped call transactions with
respect to 50% of the principal amount of the 2018 Notes and 50% of the
principal amount of the 2020 Notes with one or more of the underwriters or
their affiliates or persons unrelated to this offering (the "hedge
counterparties").The capped call transactions are generally expected to
reduce potential dilution to BioMarin's common stock upon conversion of the
relevant Notes in excess of the principal amount of such converted Notes. The
cap price of the capped call transactions entered into with respect to 50% of
the principal amount of each of the 2018Notes and the 2020 Notes will
initially be, in each case, approximately $121.05, which represents a premium
of approximately 80% over the NASDAQ closing price on October 8, 2013 and is
subject to certain adjustments under the terms of such capped call
transactions. If the underwriters exercise their option to purchase additional
Notes, BioMarin intends to enter into additional capped call transactions with
the hedge counterparties with respect to 50% of the principal amount of such
additional Notes.

BioMarin has been advised by the hedge counterparties that in connection with
establishing their initial hedges of the capped call transactions, the hedge
counterparties (or their affiliates) expect to enter into various derivative
transactions with respect to BioMarin's common stock concurrently with, and/or
purchase shares of BioMarin's common stock shortly after, the pricing of the
relevant Notes. These activities could have the effect of increasing, or
reducing the size of any decrease in, the price of the relevant Notes and/or
BioMarin's common stock concurrently with, or shortly after, the pricing of
the relevant Notes.

The offering of the Notes has been registered under the Securities Act of
1933, as amended, and for additional information about the Notes, the offering
and the capped call transactions, BioMarin refers you to its Registration
