For Immediate Release:

            BioMarin Announces Second Quarter 2002 Financial Results

        Conference Call and Webcast to be Held Today at 4:15 PM ET (2215 CET)

Novato, CA, August 1, 2002 - BioMarin  Pharmaceutical Inc. (Nasdaq and Swiss SWX
New Market: BMRN) today announced financial results for its second quarter ended
June 30, 2002.  The net loss was $14.4 million  ($0.27 per share) for the second
quarter  of 2002  compared  to $12.0  million  ($0.30  per share) for the second
quarter of 2001.  The net loss was $41.0  million  ($0.77 per share) for the six
months ended June 30, 2002 compared to $21.7  million  ($0.57 per share) for the
six months  ended June 30,  2001.  BioMarin  had  $100.6  million in cash,  cash
equivalents and short-term investments as of June 30, 2002.

The net loss in the second  quarter of 2002 was  primarily  due to the continued
development  of the Company's  lead product  programs:  AldurazymeTM  for MPS I,
AryplaseTM for MPS VI, and NeutralaseTM for heparin reversal.

Recent Achievements

Fredric D. Price,  BioMarin's  Chairman and Chief Executive Officer,  commented,
"Since  May,  we have made  significant  progress  in our  clinical  development
programs.  I am pleased to  highlight  the  following  recent  achievements  and
upcoming events:"

o        BioMarin received a U.S. patent covering AldurazymeTM for the treatment
         of MPS I. Aldurazyme is a specific form of purified recombinant human
         alpha-L-iduronidase that is being investigated as an enzyme replacement
         therapy for MPS I, a life-threatening genetic disease for which no
         specific drug treatments currently exist. The patent claims unique
         characteristics of the pharmaceutical composition of Aldurazyme. This
         patent, which protects a highly purified form of alpha-L-iduronidase,
         supports the intellectual property position for using Aldurazyme to
         treat MPS I.

o        BioMarin and Genzyme submitted the final portion of their "rolling"
         Biologics License Application (BLA) for Aldurazyme to the U.S. Food and
         Drug Administration (FDA). The final portion of the BLA includes
         clinical data from the six-month, placebo-controlled Phase 3 trial of
         Aldurazyme, six months of data from the ongoing open-label Phase 3
         extension study, and three years of data from the Phase 1 trial and
         extension study. As part of the BLA submission, BioMarin and Genzyme
         have formally requested Priority Review.



o        BioMarin appointed a new Chief Financial Officer and elected three new
         members to its Board of Directors. Louis Drapeau joined BioMarin as
         Vice President, Finance & Chief Financial Officer, and Secretary. In
         addition, Franz Cristiani, retired Partner of Arthur Andersen, LLP,
         Elaine Heron, PhD, Chairman and CEO of Picoliter Inc., and Vijay
         Samant, President and CEO of Vical Incorporated, were elected to the
         Board.

o        BioMarin established a Science Advisory Board (SAB) comprised of
         leading scientists and physicians who will provide management with
         critical scientific and strategic input as the Company continues to
         develop its pipeline of enzyme therapeutics.

o        The principal investigator from the Phase 1 clinical trial of Aryplase
         for MPS VI presented positive findings from the trial's extension study
         that indicate Aryplase continues to be well-tolerated at both dose
         levels by the five patients who have received treatment for a total of
         48 weeks. In addition, the 1.0 mg/kg dose continued to produce a
         greater sustained reduction than the 0.2 mg/kg dose in the excretion of
         urinary glycosaminoglycans (GAGs) over 48 weeks. The reduction in
         urinary GAGs indicates that Aryplase is breaking down the complex
         carbohydrate materials that otherwise accumulate in patients with MPS
         VI and lead to the debilitating and life-threatening symptoms of the
         disease.

o        Investigators from the Phase 3 clinical trial of Aldurazyme for MPS I
         presented detailed results from the double-blind portion of the trial
         and preliminary six-month findings from the trial's ongoing open-label
         extension study. Data from the extension study indicate patients who
         received Aldurazyme for twelve months continued to improve upon the
         results seen in the first six months of treatment.

o        BioMarin commenced preclinical studies of NeuroTransTM and initiated
         key steps to continue building the technology's intellectual property
         position. NeuroTrans is the proprietary brain delivery technology that
         BioMarin is developing to treat neurological problems associated with
         many lysosomal storage disorders.

Upcoming Events

o        BioMarin will hold its annual stockholders' meeting on August 13, 2002
         at 10:00 a.m. The annual meeting will be held at the Embassy Suites
         Hotel, located at 101 McInnis Parkway in San Rafael, CA. At this year's
         annual meeting, BioMarin stockholders will vote on, among other items,
         the Company's planned acquisition of all the outstanding shares of
         Glyko Biomedical Ltd. Glyko Biomedical's principal asset is an
         approximate 21% ownership interest in the capital stock of BioMarin.



o        BioMarin and Genzyme expect a decision regarding FDA's acceptance of
         the Aldurazyme BLA and its Priority Review status by the end of
         September 2002.

o        BioMarin plans to initiate the first of two Phase 3 clinical trials of
         NeutralaseTM for the reversal of heparin following Coronary Artery
         Bypass Graft (CABG) surgery during the third quarter of this year.

BioMarin  will host a  conference  call and  webcast to discuss  second  quarter
financial  results today at 4:15 PM ET (2215 CET). This event can be accessed on
the BioMarin website at: http://investor.biomarinpharm.com.
