                                     SUMMARY

     This prospectus contains forward looking statements which involve risks and
uncertainties. Our actual results could differ materially from those anticipated
in these forward  looking  statements as a result of certain  factors  appearing
under "Risk Factors" and elsewhere in this prospectus.

     The  following  summary  does not contain all the  information  that may be
important to you. You should read the entire Prospectus, including the financial
statements and other  information  incorporated by reference in this prospectus,
before making an investment decision.

     BioMarin  Pharmaceutical  Inc.  (BioMarin)  is a developer of  carbohydrate
enzyme therapies for debilitating,  life-threatening,  chronic genetic disorders
and other  diseases and  conditions.  In April 1999, we completed a twelve-month
patient  evaluation  for the initial  clinical  trial of our lead drug  product,
Aldurazyme(TM), for the treatment of mucopolysaccharidosis-I or MPS-I, a serious
genetic  disorder.  The results were presented at the American Society for Human
Genetics in October 1999. We continue to collect data from the ongoing treatment
of these original  patients.  In September  1998, we established a joint venture
with Genzyme for the worldwide  development and commercialization of Aldurazyme.
Aldurazyme  has received  fast track  designation  for the treatment of the more
severe forms of MPS-I. The U.S. Food and Drug  Administration  (FDA) has granted
Aldurazyme  an orphan  drug  designation  giving us  exclusive  rights to market
Aldurazyme  to treat  MPS-I for seven  years  from the date of FDA  approval  if
Aldurazyme  is the first  product to be approved by the FDA for the treatment of
MPS-I.

     MPS-I  is a  life-threatening  genetic  disorder  caused  by the  lack of a
sufficient  quantity of the enzyme  (alpha)-L-iduronidase,  which  affects about
3,400  patients in developed  countries,  including  approximately  1,000 in the
United  States  and  Canada.  Patients  with MPS-I  have  multiple  debilitating
symptoms  resulting from the buildup of carbohydrate  residues in all tissues in
the body. These symptoms  include delayed  physical and mental growth,  enlarged
livers and spleens,  skeletal and joint deformities,  airway obstruction,  heart
disease,  reduced  endurance and pulmonary  function,  and impaired  hearing and
vision. Most children with MPS-I will die from complications associated with the
disease before adulthood.

     Aldurazyme is a specific form of  recombinant  human  (alpha)-L-iduronidase
that replaces a genetic deficiency of  (alpha)-L-iduronidase  in MPS-I patients.
The initial  clinical  trial  treated ten  patients  with MPS-I at five  medical
centers  in the  United  States.  Based on data  collected  during  the  initial
twelve-month  evaluation period,  Aldurazyme met the primary endpoints set forth
in  the   investigational   new  drug  application.   In  addition,   Aldurazyme
demonstrated  efficacy  according to various secondary  endpoints in each of the
patients.  In  collaboration  with  Genzyme,  we plan to  initiate  a Phase  III
Confirmatory Clinical Trial of Aldurazyme in the fourth quarter of 2000 with the
intention  to file a Biologics  License  Application  (BLA) with the FDA late in
2001, pending the successful outcome of the Phase III Confirmatory Trial.

     In  August  2000,  our Galli  Drive  manufacturing  facility  and a smaller
clinical manufacturing  laboratory in our Bel Marin Keys Boulevard facility were
both  subjected to an extensive  inspection by the State of California  Food and
Drug Branch and were granted licenses to produce clinical product.

     We have submitted an  Investigational  New Drug Application for recombinant
human  N-acetylgalactosamine-4-sulfatase  also known as arylsulfatase B or rhASB
(formerly  referred to as BM102) and  received FDA  acceptance  to begin a Phase
I/II  clinical  trial in  enzyme  replacement  therapy  for  MPS-VI,  which  was
initiated on October 11, 2000. MPS-VI, also known as Maroteaux-Lamy syndrome, is
similar in its clinical  symptoms to MPS-I.  However,  MPS-VI does not appear to
have  the   central   nervous   system   involvement   and  mental   retardation
characteristics of the most severe form of MPS-I. We are manufacturing  clinical
bulk rhASB in the Bel Marin Keys  Boulevard  facility.  RhASB has received  fast
track and orphan drug designations by the FDA.

     We have  successfully  conducted  preclinical  studies of our burn  enzyme,
Vibriolysin  (formerly  referred to as BM202),  for use in burn  debridement and
grafting in pigs and mice.  We expect to submit an  application  to the FDA or a
foreign equivalent to begin a clinical trial for Vibriolysin by mid-year 2001.

     Our  principal  executive  offices  are  located  at  371  Bel  Marin  Keys
Boulevard,  Suite  210,  Novato,  CA 94949  and our  telephone  number  is (415)
884-6700.

                                  RISK FACTORS

     An  investment  in our  common  stock  involves a high  degree of risk.  We
operate in a dynamic and rapidly changing  industry that involves numerous risks
and  uncertainties.  Before  purchasing these  securities,  you should carefully
consider the following risk factors,  as well as other information  contained in
this prospectus or incorporated by reference into this prospectus, in evaluating
an  investment  in the  securities  offered  by this  prospectus.  The risks and
uncertainties  described  below are not the only ones we face.  Other  risks and
uncertainties,  including those that we do not currently consider material,  may
impair our business.  If any of the risks discussed  below actually  occur,  our
business,  financial  condition,  operating  results  or  cash  flows  could  be
materially adversely affected.  This could cause the trading price of our common
stock to decline, and you may lose all or part of your investment.

If we continue to incur operating  losses for a period longer than  anticipated,
we may be unable to continue our  operations at planned  levels and be forced to
reduce or discontinue operations.

     We are in an early  stage of  development  and have  operated at a net loss
since we were  formed.  Since we began  operations  in March 1997,  we have been
engaged  primarily in research and  development.  We have no sales revenues from
any of our drug  products.  As of  September  30,  2000,  we had an  accumulated
deficit of  approximately  $70.1 million.  We expect to continue to operate at a
net  loss at  least  through  2002.  Our  future  profitability  depends  on our
receiving  regulatory  approval  of our  drug  candidates  and  our  ability  to
successfully  manufacture and market any approved drugs,  either by ourselves or
jointly  with  others.  The  extent  of our  future  losses  and the  timing  of
profitability  are  highly  uncertain.  If we fail to become  profitable  or are
unable to sustain  profitability on a continuing basis, then we may be unable to
continue our operations.

     Because  of  the  relative  small  size  and  scale  of  our   wholly-owned
subsidiary,  Glyko,  Inc.,  profits  from  its  products  and  services  will be
insufficient to offset the expenses associated with our pharmaceutical business.
As a result,  we expect that operating losses will continue and increase for the
foreseeable future.

If we fail to obtain the capital  necessary to fund our  operations,  we will be
unable to complete our product development programs.

     In the future, we may need to raise substantial  additional capital to fund
operations.  We cannot be certain  that any  financing  will be  available  when
needed. If we fail to raise additional  financing as we need it, we will have to
delay or terminate some or all of our product development programs.

     We expect to  continue  to spend  substantial  amounts of  capital  for our
operations for the foreseeable future.  Activities which will require additional
expenditures include:

o    Research and development programs

o    Preclinical studies and clinical trials

o    Process development, including quality systems for product manufacture

o    Regulatory processes in the United States and international jurisdictions

o    Commercial scale manufacturing capabilities

o    Expansion of sales and marketing activities

The amount of capital we will need depends on many factors, including:

o    The progress, timing and scope of our research and development programs

o    The  progress,  timing and scope of our  preclinical  studies and  clinical
     trials

o    The time and cost necessary to obtain regulatory approvals

                                       3


o    The time and cost  necessary  to develop  commercial  processes,  including
     quality systems

o    The time and cost  necessary  to build  our  manufacturing  facilities  and
     obtain the necessary regulatory approvals for those facilities

o    The time  and  cost  necessary  to  respond  to  technological  and  market
     developments

o    Any  changes  made  or  new  developments  in our  existing  collaborative,
     licensing and other commercial relationships

o    Any new collaborative, licensing and other commercial relationships that we
     may establish

     Moreover,  our fixed  expenses  such as rent,  license  payments  and other
contractual  commitments are substantial and will increase in the future.  These
fixed expenses will increase because we may enter into:

o    Additional leases for new facilities and capital equipment

o    Additional licenses and collaborative agreements

o    Additional   contracts  for  consulting,   maintenance  and  administrative
     services

o    Additional contracts for product manufacturing

     We  believe  that the cash,  cash  equivalents  and  short-term  investment
securities  balances  at  September  30,  2000  will be  sufficient  to meet our
operating and capital requirements through mid-year 2001. This estimate is based
on assumptions and estimates,  which may prove to be wrong. As a result,  we may
need or choose to obtain additional financing during that time.

If we fail to obtain regulatory approval to commercially manufacture or sell any
of our future drug  products,  or if  approval is delayed,  we will be unable to
generate revenue from the sale of our products.

     We must obtain  regulatory  approval to market our products in the U.S. and
foreign jurisdictions.

     We must obtain  regulatory  approval  before  marketing or selling our drug
products.  In the United States,  we must obtain FDA approval for each drug that
we intend to  commercialize.  The FDA approval process is typically  lengthy and
expensive,  and approval is never certain.  Products distributed abroad are also
subject to foreign government regulation. None of our drug products has received
regulatory  approval to be commercially  marketed and sold. If we fail to obtain
regulatory  approval,  we will be unable to market  and sell our drug  products.
Because of the risks and  uncertainties in  biopharmaceutical  development,  our
drug  candidates  could  take a  significantly  longer  time to gain  regulatory
approval than we expect or may never gain  approval.  If regulatory  approval is
delayed,  our  management's  credibility,  the  value  of our  Company  and  our
operating results will be adversely affected.

To obtain regulatory  approval to market our products,  preclinical  studies and
costly and  lengthy  clinical  trials  may be  required  and the  results of the
studies and trials are highly uncertain.

     As part of the FDA approval process,  we must conduct,  at our own expense,
preclinical studies in the laboratory on animals,  and clinical trials on humans
for each  drug  candidate.  We expect  the  number of  preclinical  studies  and
clinical  trials  that the FDA will  require  will  vary  depending  on the drug
product,  the disease or  condition  the drug is being  developed to address and
regulations  applicable to the particular  drug. We may need to perform multiple
preclinical  studies using various  doses and  formulations  before we can begin
clinical  trials,  which could  result in delays in our ability to market any of
our  drug  products.  Furthermore,  even  if  we  obtain  favorable  results  in
preclinical  studies on  animals,  the  results  in humans may be  significantly
different.

     After we have conducted preclinical studies in animals, we must demonstrate
that our drug  products  are safe and  efficacious  for use on the target  human
patients in order to receive regulatory approval for commercial sale. Adverse or
inconclusive  clinical results would stop us from filing for regulatory approval
of our products.  Additional  factors that can cause delay or termination of our
clinical trials include:

                                       4


o    Slow patient enrollment

o    Longer treatment time required to demonstrate efficacy

o    Lack of sufficient supplies of the drug candidate

o    Adverse medical events or side effects in treated patients

o    Lack of effectiveness of the drug candidate being tested

o    Regulatory requests for additional clinical trials

     Typically, if a drug product is intended to treat a chronic disease, safety
and efficacy  data must be gathered over an extended  period of time,  which can
range from six months to three years or more.  In addition,  clinical  trials on
humans are typically  conducted in three phases.  The FDA generally requires two
pivotal  clinical  trials that  demonstrate  substantial  evidence of safety and
efficacy and appropriate  dosing in a broad patient population at multiple sites
to support an application for regulatory approval. If a drug is intended for the
treatment of a serious or  life-threatening  condition and the drug demonstrates
the potential to address unmet medical needs for this condition,  fewer clinical
trials  may  be  sufficient  to  prove  safety  and  efficacy  under  the  FDA's
Modernization Act of 1997.

     In April 1999,  we  completed a  twelve-month  patient  evaluation  for the
initial clinical trial of our lead drug product,  Aldurazyme,  for the treatment
of MPS-I.  The results were presented at the American Society for Human Genetics
in October 1999. We continue to collect data from the ongoing treatment of these
original patients. The initial clinical trial treated ten patients with MPS-I at
five  medical   centers  in  the  United   States.   Two  of  the  original  ten
patients enrolled  in the first clinical trial of Aldurazyme died in 2000. Based
on medical  data  collected  from  clinical  investigative  sites,  neither case
directly  implicated  treatment with Aldurazyme as the cause of death.  The data
suggest that one patient died due to a combination  of systemic  viral  illness,
residual MPS I coronary disease, and external factors. This patient had received
103 weeks of Aldurazyme administration.  For the other patient, the data suggest
that the patient died due to complications following posterior spinal fusion for
scoliosis. This patient had received 127 weeks of Aldurazyme administration. The
fast track  designation  for Aldurazyme may not actually lead to a faster review
process.

     Although  Aldurazyme  has  obtained  a fast  track  designation,  we cannot
guarantee a faster review process or faster approval  compared to the normal FDA
procedures.

We will not be able to sell our products if we fail to comply with manufacturing
regulations.

     Before we can begin commercial  manufacture of our products, we must obtain
regulatory  approval of our  manufacturing  facility and  process.  In addition,
manufacture  of our drug  products  must  comply  with the  FDA's  current  Good
Manufacturing   Practices   regulations,   commonly  known  as  cGMP.  The  cGMP
regulations  govern quality control and  documentation  policies and procedures.
Our manufacturing  facilities are continuously subject to inspection by the FDA,
the State of California  and foreign  regulatory  authorities,  before and after
product approval. Our Galli Drive and our Bel Marin Keys Boulevard manufacturing
facilities  have been  inspected  and  licensed by the State of  California  for
clinical pharmaceutical  manufacture.  We cannot guarantee that these facilities
will pass federal or international  regulatory  inspection.  We cannot guarantee
that we, or any potential third-party manufacturer of our drug products, will be
able to comply with cGMP regulations.

     We must pass Federal,  state and European  regulatory  inspections,  and we
must manufacture three process qualification batches (five process qualification
batches  for  Europe) to final  specifications  under cGMP  controls  before the
Aldurazyme BLA can be approved.  We cannot ensure that we will  manufacture  the
process  qualification batches or pass the inspections in a timely manner, if at
all.

If we fail to obtain orphan drug  exclusivity for our products,  our competitors
may sell products to treat the same conditions and our revenues may be reduced.

     As part of our business  strategy,  we intend to develop  drugs that may be
eligible for FDA orphan drug designation. Under the Orphan Drug Act, the FDA may
designate a product as an orphan  drug if it is a drug  intended to treat a rare
disease or  condition,  defined as a patient  population of less than 200,000 in

                                       5

the United  States.  The  company  that  obtains  the first FDA  approval  for a
designated orphan drug for a given rare disease receives  marketing  exclusivity
for use of that  drug for the  stated  condition  for a period  of seven  years.
However,  different  drugs  can be  approved  for the  same  condition.  Similar
regulations are available in the European Union with a ten-year period of market
exclusivity.

     Because the extent and scope of patent  protection for our drug products is
limited, orphan drug designation is particularly important for our products that
are eligible  for orphan drug  designation.  We plan to rely on the  exclusivity
period under the orphan drug designation to maintain a competitive  position. If
we do not obtain orphan drug exclusivity for our drug products which do not have
patent protection, our competitors may then sell the same drug to treat the same
condition.

     We  received  orphan  drug  designation  from  the  FDA for  Aldurazyme  in
September 1997. In February 1999, we received orphan drug  designation  from the
FDA for rhASB for the treatment of MPS-VI.  Even though we have obtained  orphan
drug  designation for these drugs and even if we obtain orphan drug  designation
for other products we develop,  we cannot guarantee that we will be the first to
obtain marketing  approval for any orphan  indication or that exclusivity  would
effectively  protect  the product  from  competition.  Orphan  drug  designation
neither shortens the development time or FDA review time of a drug so designated
nor gives the drug any advantage in the FDA review or approval process.

Because  the  target  patient  populations  for our  products  are small we must
achieve  significant  market  share and obtain high per  patient  prices for our
products to achieve profitability.

     Our  initial  drug   candidates   target   disorders   with  small  patient
populations.  As a result, our per patient prices must be high enough to recover
our development costs and achieve profitability. For example, two of our initial
drug products in genetic disorders,  Aldurazyme and rhASB,  target patients with
MPS-I and MPS-VI,  respectively.  We estimate that there are approximately 3,400
patients with MPS-I and 1,100  patients with MPS-VI in the developed  world.  We
believe  that we will need to market  worldwide  to achieve  significant  market
share. In addition, we are developing other drug candidates to treat conditions,
such as other  genetic  diseases  and serious burn  wounds,  with small  patient
populations.  We cannot  be  certain  that we will be able to obtain  sufficient
market share for our drug products at a price high enough to justify our product
development efforts.

If we fail to obtain an adequate level of reimbursement for our drug products by
third-party  payors,  there  would be no  commercially  viable  markets  for our
products.

     The course of  treatment  for  patients  with  MPS-I  using  Aldurazyme  is
expected to be expensive.  We expect patients to need treatment throughout their
lifetimes.  We expect  that most  families  of  patients  will not be capable of
paying  for this  treatment  themselves.  There will be no  commercially  viable
market for Aldurazyme without reimbursement from third-party payors.

     Third-party  payors,  such as government or private  health care  insurers,
carefully  review  and  increasingly  challenge  the price  charged  for  drugs.
Reimbursement  rates from private  companies vary  depending on the  third-party
payor,  the  insurance  plan  and  other  factors.   Reimbursement   systems  in
international   markets  vary  significantly  by  country  and  by  region,  and
reimbursement  approvals  must be obtained  on a  country-by-country  basis.  We
cannot be certain  that  third-party  payors will pay for the costs of our drugs
and the courses of treatment.  Even if we are able to obtain  reimbursement from
third-party payors, we cannot be certain that reimbursement rates will be enough
to  allow us to  profit  from  sales of our  drugs  or to  justify  our  product
development expenses.

     We currently have no expertise obtaining  reimbursement.  We expect to rely
on the expertise of our joint venture  partner  Genzyme to obtain  reimbursement
for the costs of Aldurazyme. We cannot predict what the reimbursement rates will
be. In addition,  we will need to develop our own  reimbursement  expertise  for
future drug candidates unless we enter into  collaborations with other companies
with the necessary expertise.

     We expect that in the future, reimbursement will be increasingly restricted
both in the United States and  internationally.  The  escalating  cost of health
care has led to increased  pressure on the health care industry to reduce costs.
Governmental  and private  third-party  payors have proposed health care reforms
and cost reductions. A number of federal and state proposals to control the cost
of health  care,  including  the cost of drug  treatments  have been made in the
United States.  In some foreign  markets,  the  government  controls the pricing
which would affect the profitability of drugs.  Current  government  regulations

                                       6

and  possible  future  legislation  regarding  health care may affect our future
revenues  from  sales of our drugs and may  adversely  affect our  business  and
prospects.

If we are unable to protect our  proprietary  technology,  we may not be able to
compete as effectively.

     Where  appropriate,  we seek patent  protection for certain  aspects of our
technology.  Meaningful  patent  protection may not be available for some of the
enzymes we are  developing,  including  Aldurazyme  and rhASB.  If we must spend
significant time and money protecting our patents, designing around patents held
by others or licensing, for large fees, patents or other proprietary rights held
by others, our business and financial prospects may be harmed.

     The patent positions of  biotechnology  products are complex and uncertain.
The  scope  and  extent  of  patent  protection  for  some of our  products  are
particularly  uncertain  because key  information  on some of the enzymes we are
developing  has existed in the public domain for many years.  Other parties have
published the  structure of the enzymes,  the methods for purifying or producing
the enzymes or the methods of treatment.  The composition and genetic  sequences
of animal  and/or  human  versions of many of our enzymes,  including  those for
Aldurazyme  and rhASB,  have been published and are believed to be in the public
domain.  The  composition  and genetic  sequences of other MPS enzymes  which we
intend to develop as  products  have also been  published.  Publication  of this
information may prevent us from obtaining  composition-of-matter  patents, which
are generally  believed to offer the strongest  patent  protection.  For enzymes
with no prospect of composition-of-matter patents, we will depend on orphan drug
status to provide us a competitive advantage.

     In addition,  our owned and licensed patents and patent applications do not
ensure  the  protection  of our  intellectual  property  for a  number  of other
reasons:

     o    We do not know whether our patent  applications  will result in actual
          patents.  For example, we may not have developed a method for treating
          a disease before others developed  similar methods.  o Competitors may
          interfere  with our patent  process in a variety of ways.  Competitors
          may claim  that  they  invented  the  claimed  invention  prior to us.
          Competitors may also claim that we are infringing on their patents and
          therefore  cannot practice our technology as claimed under our patent.
          Competitors  may also  contest  our  patents  by  showing  the  patent
          examiner that the  invention  was not  original,  was not novel or was
          obvious.  As  a  Company,  we  have  no  meaningful   experience  with
          competitors interfering with our patents or patent applications.

     o    Enforcing patents is expensive and may absorb  significant time of our
          management.  In litigation,  a competitor  could claim that our issued
          patents are not valid for a number of reasons. If the court agrees, we
          would lose that patent.

     o    Even if we  receive  a  patent,  it may  not  provide  much  practical
          protection.  If we receive a patent with a narrow scope,  then it will
          be easier for  competitors to design  products that do not infringe on
          our patent.

     In addition,  competitors also seek patent protection for their technology.
There are many patents in our field of technology,  and we cannot guarantee that
we do not  infringe  on those  patents or that we will not  infringe  on patents
granted in the future.  If a patent  holder  believes  our product  infringes on
their  patent,  the  patent  holder may sue us even if we have  received  patent
protection  for our  technology.  If someone  else  claims we  infringe on their
technology, we would face a number of issues, including:

     o    Defending a lawsuit takes significant time and can be very expensive.

     o    If the court  decides that our product  infringes on the  competitor's
          patent, we may have to pay substantial damages for past infringement.

     o    The court may prohibit us from selling or licensing the product unless
          the patent holder  licenses the patent to us. The patent holder is not
          required to grant us a license. If a license is available, we may have
          to pay substantial royalties or grant cross-licenses to our patents.

     o    Redesigning our product so it does not infringe may not be possible or
          could require substantial funds and time.

                                       7

     It  is  also  unclear   whether  our  trade  secrets  will  provide  useful
protection.  While we use reasonable  efforts to protect our trade secrets,  our
employees  or  consultants  may   unintentionally   or  willfully  disclose  our
information  to  competitors.  Enforcing  a claim that  someone  else  illegally
obtained and is using our trade secrets,  like patent  litigation,  is expensive
and time  consuming,  and the  outcome is  unpredictable.  In  addition,  courts
outside the United States are sometimes  less willing to protect trade  secrets.
Our competitors may  independently  develop  equivalent  knowledge,  methods and
know-how.

     We may also support and  collaborate  in research  conducted by  government
organizations  or by  universities.  We cannot guarantee that we will be able to
acquire  any  exclusive  rights to  technology  or products  derived  from these
collaborations.  If we do not  obtain  required  licenses  or  rights,  we could
encounter delays in product  development while we attempt to design around other
patents or even be prohibited from developing, manufacturing or selling products
requiring these licenses. There is also a risk that disputes may arise as to the
rights to technology or products developed in collaboration with other parties.

The United  States Patent and Trademark  Office  recently  issued a patent which
related to (alpha)-L-iduronidase.  If Aldurazyme infringes on this patent and we
are not able to  successfully  challenge it, we may be prevented  from producing
Aldurazyme unless and until we obtain a license.

     The United  States  Patent and Trademark  Office  recently  issued a patent
which includes claims related to  (alpha)-L-iduronidase.  Our lead drug product,
Aldurazyme,  may infringe on this patent. We believe that this patent is invalid
and  intend  to  challenge  it on a number of  grounds.  Our  challenges  may be
unsuccessful.  Even  if  we  are  successful,  challenging  the  patent  may  be
expensive,  require our management to devote significant time to this effort and
may delay commercialization of our product in the United States.

     The patent holder has granted an exclusive license for products relating to
this  patent  to one of  our  competitors.  If we  are  unable  to  successfully
challenge  the  patent,  we may be unable to  produce  Aldurazyme  in the United
States unless we can obtain a sub-license from the current licensee. The current
licensee  is not  required  to  grant us a  license  and  even if a  license  is
available,  we may have to pay  substantial  license fees which could  adversely
affect our business and operating results.

If our joint  venture  with  Genzyme  were  terminated,  we could be barred from
commercializing  Aldurazyme or our ability to commercialize  Aldurazyme would be
delayed or diminished.

     We are relying on Genzyme to apply the expertise it has  developed  through
the launch and sale of Ceredase(R) and Cerezyme(R)  enzymes for Gaucher disease,
a  rare  genetic  disorder,  to  the  marketing  of our  initial  drug  product,
Aldurazyme.  Because it is our initial product, our operations are substantially
dependent upon the  development of  Aldurazyme.  We have no experience  selling,
marketing or obtaining  reimbursement for pharmaceutical  products. In addition,
without Genzyme we would be required to pursue foreign regulatory approvals.  We
have no experience in seeking foreign regulatory approvals.

     We cannot  guarantee  that Genzyme will devote the  resources  necessary to
successfully  market  Aldurazyme.  In addition,  either party may  terminate the
joint venture for specified reasons, including if the other party is in material
breach of the  agreement or has  experienced a change of control or has declared
bankruptcy  and  also is in  breach  of the  agreement.  Either  party  may also
terminate the  agreement  upon  one-year  prior  written  notice for any reason.
Furthermore,  we may terminate the joint venture if Genzyme fails to fulfill its
contractual  obligation to pay us $12.1 million in cash upon the approval of the
BLA for Aldurazyme.

     Upon  termination  of the joint  venture  one party  must buy out the other
party's  interest  in the joint  venture.  The party who buys out the other will
then  also  obtain,  exclusively,  all  rights  to  Aldurazyme  and any  related
intellectual property and regulatory approvals.

     If the joint  venture is  terminated  by Genzyme  for a breach on our part,
Genzyme would be granted,  exclusively,  all of the rights to Aldurazyme and any
related intellectual property and regulatory approvals and would be obligated to
buy out our interest in the joint venture.  We would then  effectively be unable
to develop and commercialize  Aldurazyme. If we terminated the joint venture for
a breach by Genzyme,  we would be obligated to buy out Genzyme's interest in the
joint  venture and, we would then be granted all of these  rights to  Aldurazyme
exclusively.   While  we  could  then  continue  to  develop  Aldurazyme,   that
development would be slowed because we would have to divert substantial  capital
to buy out Genzyme's interest in the joint venture. We would then either have to
search for a new partner to  commercialize  the  product  and to obtain  foreign
regulatory approvals or have to develop these capabilities ourselves.

                                       8


     If the joint venture is terminated by us without cause,  Genzyme would have
the option, exercisable for one year, to immediately buy out our interest in the
joint venture and obtain all rights to Aldurazyme exclusively.  If the agreement
is terminated by Genzyme  without cause,  we would have the option,  exercisable
for one year, to immediately buy out Genzyme's interest in the joint venture and
obtain these  exclusive  rights.  In event of  termination of the buy out option
without exercise by the non-terminating  party as described above, all right and
title to Aldurazyme is to be sold to the highest bidder, with the proceeds to be
split equally between Genzyme and us.

     If the joint venture is terminated by us because  Genzyme fails to make the
$12.1  million  payment to us upon FDA  approval of the BLA for  Aldurazyme,  we
would be  obligated  to buy  Genzyme's  interest in the joint  venture and would
obtain all rights to Aldurazyme exclusively.  If the joint venture is terminated
by either party because the other  declared  bankruptcy and is also in breach of
the agreement, the terminating party would be obligated to buy out the other and
would  obtain  all rights to  Aldurazyme  exclusively.  If the joint  venture is
terminated by a party  because the other party  experienced a change of control,
the terminating  party shall notify the other party, the offeree,  of its intent
to buy out the  offeree's  interest in the joint venture for a stated amount set
by the terminating party at its discretion.  The offeree must then either accept
this offer or agree to buy the terminating party's interest in the joint venture
on those same terms.  The party who buys out the other would then have exclusive
rights to Aldurazyme.

     If we were obligated, or given the option, to buy out Genzyme's interest in
the joint  venture,  and gain exclusive  rights to  Aldurazyme,  we may not have
sufficient  funds to do so and we may not be able to obtain the  financing to do
so.  If we fail to buy out  Genzyme's  interest  we may be held in breach of the
agreement  and may lose any claim to the rights to  Aldurazyme  and the  related
intellectual  property and regulatory  approvals.  We would then  effectively be
prohibited from developing and commercializing the product.

     Termination  of the  joint  venture  in  which  we  retain  the  rights  to
Aldurazyme  could cause us  significant  delays in product  launch in the United
States,  difficulties  in  obtaining  third-party  reimbursement  and  delays or
failure  to obtain  foreign  regulatory  approval,  any of which  could hurt our
business  and  results  of  operations.  Since  Genzyme  funds  50% of the joint
venture's operating expenses,  the termination of the joint venture would double
our  financial  burden and reduce the funds  available  to us for other  product
programs.

If we are unable to manufacture  our drug products in sufficient  quantities and
at  acceptable  cost,  we may be unable to meet demand for our products and lose
potential revenues or have reduced margins.

     As an organization,  we have no experience  manufacturing  drug products in
volumes that will be necessary to support  commercial  sales. Our  manufacturing
process  may not meet  initial  expectations  as to  schedule,  reproducibility,
yields,   purity,   costs,  quality,  and  other  measurements  of  performance.
Improvements in manufacturing  processes typically are very difficult to achieve
and are often very  expensive.  We cannot know with  certainty how long it might
take to make  improvements  if it became  necessary to do so. If we contract for
manufacturing  services with an unproven  process,  our contractor is subject to
the same uncertainties, high standards and regulatory controls.

If we are unable to establish and maintain commercial scale manufacturing within
our planned time and cost  parameters,  sales of our products and our  financial
performance will be adversely affected.

     We may  encounter  problems  with any of the  following  if we  attempt  to
increase the scale or size of manufacturing:

     o    Design,  construction and  qualification  of manufacturing  facilities
          that meet regulatory requirements

     o    Production yields

     o    Purity

     o    Quality control and assurance systems

     o    Shortages of qualified personnel

     o    Compliance with regulatory requirements

                                       9


     We have  constructed  and  built-out  a total of 41,200  square feet at our
Novato  facilities for  manufacturing  capability  for Aldurazyme and rhASB.  We
expect to expand the Galli Drive  facility in stages  over time,  which  creates
additional   operational   complexity  and   challenges.   We  expect  that  the
manufacturing process of all of our new products,  including rhASB, will require
lengthy  significant  time and resources before we can begin to manufacture them
(or have them manufactured by third parties) in commercial quantity.  Even if we
can establish the necessary  capacity,  we cannot be certain that  manufacturing
costs will be commercially reasonable,  especially if third-party  reimbursement
is substantially lower than expected.

     In order to achieve  our product  cost  targets we must  develop  efficient
manufacturing processes either by:

     o    Improving the product  yield from our current cell lines,  colonies of
          cells which have a common genetic make-up,

     o    Improving the processes licensed from others, or

     o    Developing  more  efficient,  lower  cost  recombinant  cell lines and
          production processes.

     A recombinant  cell line is a cell line with foreign DNA inserted  which is
used to  produce  a  protein  that it would  not have  otherwise  produced.  The
development  of a stable,  high  production  cell  line for any given  enzyme is
risky,  expensive and  unpredictable  and may not result in adequate yields.  In
addition, the development of protein purification processes is difficult and may
not produce the high purity required with acceptable  yield and costs or may not
result in  adequate  shelf-lives  of the final  products.  If we are not able to
develop  efficient  manufacturing  processes,  the  investment in  manufacturing
capacity sufficient to satisfy market demand will be much greater and will place
heavy  financial  demands upon us. If we do not achieve our  manufacturing  cost
targets,  we will have lower  margins and reduced  profitability  in  commercial
production and larger losses in manufacturing start-up phases.

If we are unable to increase our marketing and  distribution  capabilities or to
enter into  agreements  with third  parties  to do so, our  ability to  generate
revenues will be diminished.

     If we cannot increase our marketing  capabilities  either by developing our
sales and marketing  organization or by entering into agreements with others, we
may be unable to successfully sell our products. If we are unable to effectively
sell our drug products, our ability to generate revenues will be diminished.

     To increase our distribution and marketing for both our drug candidates and
our Glyko,  Inc.  products,  we will have to increase  our  current  sales force
and/or enter into third-party marketing and distribution  agreements.  We cannot
guarantee that we will be able to hire in a timely manner,  the qualified  sales
and marketing personnel we need, if at all. Nor can we guarantee that we will be
able to enter into any marketing or distribution agreements on acceptable terms,
if at all. If we cannot increase our marketing capabilities as we intend, either
by increasing  our sales force or entering into  agreements  with third parties,
sales of our products may be adversely affected.

     Under our joint venture with Genzyme,  Genzyme is responsible for marketing
and  distributing  Aldurazyme.  We  cannot  guarantee  that  we  will be able to
establish sales and  distribution  capabilities  or that the joint venture,  any
future collaborators or we will successfully sell any of our drug candidates.

If we fail to compete  successfully,  our revenues and operating results will be
adversely affected.

     Our competitors may develop,  manufacture and market products that are more
effective or less expensive than ours. They may also obtain regulatory approvals
for their products faster than we can obtain them, including those products with
orphan drug  designation,  or commercialize  their products before we do. If our
competitors  successfully  commercialize  a product,  which  treats a given rare
genetic disease before we do, we will effectively be precluded from developing a
product  to treat that  disease  because  the  patient  populations  of the rare
genetic  diseases are so small. If our competitor gets orphan drug  exclusivity,
we could be  precluded  from  marketing  our version for seven  years.  However,
different  drugs can be approved for the same  condition.  These  companies also
compete  with  us  to  attract   qualified   personnel  and   organizations  for
acquisitions, joint ventures or other collaborations.  They also compete with us
to attract  academic  research  institutions  as partners  and to license  these
institutions' proprietary technology. If our competitors successfully enter into
partnering   arrangements   or  license   agreements   with  academic   research
institutions,   we  will  then  be  precluded   from  pursuing   those  specific
opportunities.  Since each of these  opportunities is unique, we may not be able
to find a substitute.  Several  pharmaceutical and biotechnology  companies have

                                       10

already established  themselves in the field of enzyme  therapeutics,  including
Genzyme, our joint venture partner. These companies have already begun many drug
development  programs,  some of  which  may  target  diseases  that we are  also
targeting,  and have already entered into partnering and licensing  arrangements
with   academic   research   institutions,   reducing   the  pool  of  available
opportunities.

     Universities  and  public  and  private  research   institutions  are  also
competitors.  While these  organizations  primarily  have  educational  or basic
research objectives, they may develop proprietary technology and acquire patents
that we may need for the  development of our drug  products.  We will attempt to
license this  proprietary  technology,  if available.  These licenses may not be
available to us on acceptable  terms, if at all. We also directly compete with a
number of these  organizations to recruit personnel,  especially  scientists and
technicians.

     We believe that established technologies provided by other companies,  such
as laboratory and testing  services firms,  compete with Glyko,  Inc.'s products
and  services.  For  example,  Glyko's  FACE(R)  Imaging  System  competes  with
alternative   carbohydrate   analytical   technologies,    including   capillary
electrophoresis,  high-pressure  liquid  chromatography,  mass  spectrometry and
nuclear magnetic  resonance  spectrometry.  These competitive  technologies have
established  customer  bases and are more widely used and accepted by scientific
and  technical   personnel  because  they  can  be  used  for   non-carbohydrate
applications.  Companies  competing  with  Glyko  may  have  greater  financial,
manufacturing and marketing resources and experience.

If we fail to manage  our growth or fail to recruit  and retain  personnel,  our
product development programs may be delayed.

     Our rapid growth has strained our  managerial,  operational,  financial and
other resources. We expect this growth to continue. We have entered into a joint
venture with Genzyme. If we receive FDA approval to market Aldurazyme, the joint
venture  will  be  required  to  devote  additional  resources  to  support  the
commercialization of Aldurazyme.

     To manage expansion effectively, we need to continue to develop and improve
our research and development capabilities, manufacturing and quality capacities,
sales and marketing  capabilities and financial and administrative  systems.  We
cannot guarantee that our staff,  financial  resources,  systems,  procedures or
controls will be adequate to support our operations or that our management  will
be able to manage successfully future market  opportunities or our relationships
with customers and other third parties.

     Our future  growth and success  depend on our  ability to recruit,  retain,
manage and motivate our  employees.  The loss of key  scientific,  technical and
managerial  personnel  may  delay  or  otherwise  harm our  product  development
programs.  Any harm to our  research  and  development  programs  would harm our
business and prospects.

     Because  of  the  specialized  scientific  and  managerial  nature  of  our
business,  we rely  heavily  on our  ability to  attract  and  retain  qualified
scientific,  technical and  managerial  personnel.  In  particular,  the loss of
Fredric D. Price,  our Chairman and Chief Executive  Officer,  or Christopher M.
Starr,  Ph.D.,  our  Vice  President  for  Research  and  Development,  could be
detrimental to us if we cannot recruit suitable replacements in a timely manner.
While Mr. Price and Dr. Starr are parties to employment  agreements  with us, we
cannot  guarantee  that they will  remain  employed  with us in the  future.  In
addition,  these  agreements  do not restrict  their  ability to compete with us
after their employment is terminated. The competition for qualified personnel in
the  biopharmaceutical  field is  intense.  We  cannot be  certain  that we will
continue to attract and retain qualified personnel necessary for the development
of our business.

If product liability lawsuits are successfully  brought against us, we may incur
substantial liabilities.

     We are exposed to the potential  product  liability  risks  inherent in the
testing,   manufacturing   and   marketing   of   human   pharmaceuticals.   The
BioMarin/Genzyme  LLC  maintains  product  liability  insurance for our clinical
trials of  Aldurazyme.  We have obtained  insurance  against  product  liability
lawsuits  for the  clinical  trials  for  rhASB.  We may be subject to claims in
connection  with our current  clinical trials for Aldurazyme and rhASB for which
the joint  venture's or our insurance  coverages are not adequate.  We cannot be
certain  that  if  Aldurazyme  receives  FDA  approval,  the  product  liability
insurance  the  joint  venture  will  need to  obtain  in  connection  with  the
commercial  sales of Aldurazyme will be available in meaningful  amounts or at a
reasonable  cost.  In addition,  we cannot be certain  that we can  successfully
defend any product  liability  lawsuit brought against us. If we are the subject
of a  successful  product  liability  claim  which  exceeds  the  limits  of any
insurance  coverage we may obtain,  we may incur  substantial  liabilities which
would adversely affect our earnings and financial condition.
                                       11

Our stock price may be volatile  and an  investment  in our stock could suffer a
decline in value.

     Our  valuation  and stock price since the  beginning  of trading  after our
initial  public  offering  have had no  meaningful  relationship  to  current or
historical  earnings,  asset values,  book value or many other criteria based on
conventional  measures of stock value. The market price of our common stock will
fluctuate due to factors including:

     o    Progress of Aldurazyme  and our other lead drug  products  through the
          regulatory process,  especially  Aldurazyme  regulatory actions in the
          United States

     o    Results of clinical trials, announcements of technological innovations
          or new products by us or our competitors

     o    Government  regulatory  action  affecting  our drug  candidates or our
          competitors'  drug  candidates  in both the United  States and foreign
          countries

     o    Developments or disputes concerning patent or proprietary rights

     o    General market  conditions for emerging  growth and  biopharmaceutical
          companies

     o    Economic conditions in the United States or abroad

     o    Actual or anticipated fluctuations in our operating results

     o    Broad market  fluctuations in the United States or in Europe may cause
          the market price of our common stock to fluctuate

     o    Changes in company  assessments  or financial  estimates by securities
          analysts

     In  addition,  the value of our common  stock may  fluctuate  because it is
listed on both the  Nasdaq  National  Market  and the Swiss  Exchange's  SWX New
Market. Listing on both exchanges may increase stock price volatility due to:

     o    Trading in different time zones

     o    Different ability to buy or sell our stock

     o    Different market conditions in different capital markets

     o    Different trading volume

     In the past, following periods of large price declines in the public market
price of a company's  securities,  securities class action  litigation has often
been  initiated  against that  company.  Litigation of this type could result in
substantial costs and diversion of management's  attention and resources,  which
would hurt our business.  Any adverse  determination  in  litigation  could also
subject us to significant liabilities.

Substantial  resales of the common  stock  which may be issued  pursuant to this
prospectus could adversely affect the price of our common stock.

     The  maximum  shares  which  may be  issued  pursuant  to  this  prospectus
represents a significant portion of our outstanding common stock. If the persons
acquiring these shares sell all or a substantial  portion of these shares on the
public market in a short period of time, the common stock available for sale may
exceed the demand and the stock price may be  adversely  affected.  In addition,
the mere  perception  that such sales  could  occur may depress the price of our
common stock.

If our officers,  directors and largest stockholder elect to act together,  they
may be able to  control  our  management  and  operations,  acting in their best
interests and not necessarily those of other stockholders.

     Our directors and officers  control  approximately  46% of the  outstanding
shares of our common stock.  Glyko Biomedical,  Ltd. owns 31% of the outstanding
shares of our capital stock. The president and chief executive  officer of Glyko
Biomedical and a significant shareholder of Glyko Biomedical serve as two of our
directors. As a result, due to their concentration of stock ownership, directors

                                       12

and officers,  if they act together,  may be able to control our  management and
operations,  and may be able to prevail on all matters  requiring a  stockholder
vote including:

     o    The election of all directors;

     o    The amendment of charter  documents or the approval of a merger,  sale
          of assets or other major corporate transactions; and

     o    The defeat of any non-negotiated takeover attempt that might otherwise
          benefit the public stockholders.

Anti-takeover  provisions in our charter  documents  and under  Delaware law may
make an  acquisition  of us, which may be beneficial to our  stockholders,  more
difficult.

     BioMarin is incorporated in Delaware.  Certain anti-takeover  provisions of
Delaware law and our charter  documents as currently in effect may make a change
in control of our company more  difficult,  even if a change in control would be
beneficial to the stockholders.  Our anti-takeover provisions include provisions
in the certificate of incorporation  providing that  stockholders'  meetings may
only be called by the board of directors and a provision in the bylaws providing
that the stockholders may not take action by written consent.  Additionally, our
board of  directors  has the  authority to issue  1,000,000  shares of preferred
stock and to determine  the terms of those  shares of stock  without any further
action by the  stockholders.  The  rights of  holders  of our  common  stock are
subject to the rights of the holders of any preferred  stock that may be issued.
The issuance of preferred  stock could make it more  difficult for a third party
to  acquire a  majority  of our  outstanding  voting  stock.  Delaware  law also
prohibits  corporations from engaging in a business combination with any holders
of 15% or more of their  capital  stock  until the holder has held the stock for
three years unless, among other  possibilities,  the board of directors approves
the  transaction.  Our board of directors  may use these  provisions  to prevent
changes in the management  and control of our company.  Also,  under  applicable
Delaware law, our board of directors may adopt additional anti-takeover measures
in the future.

                                       14




                         MATERIAL CHANGES TO OUR COMPANY

     Effective November 1, 2000, Mr. Fredric D. Price was elected as a member of
our board of  directors  and  appointed  as our  Chairman  and  Chief  Executive
Officer. Immediately prior to such appointment, Mr. Grant W. Denison resigned as
Chairman and Chief Executive  Officer.  Mr. Denison continues to serve as one of
our directors.

     From September 1994 until  September  2000, Mr. Price was President,  Chief
Executive  Officer  and a member  of the board of  directors  of AMBI,  Inc.,  a
biotechnology and nutrition company. From July 1991 to September 1994, Mr. Price
served as Vice President Finance and  Administration and Chief Financial Officer
of  Regeneron  Pharmaceuticals,  Inc.,  a  biotechnology  company.  He  is  also
currently  a member  of the  advisory  board  of  Equity4Life  AG, a  healthcare
investment  company based in Zurich,  Switzerland.  Mr. Price,  55, received his
B.A.  from  Dartmouth  College  and a M.B.A.  from  the  Wharton  School  of the
University of Pennsylvania.

     In connection  with Mr. Price's  employment,  we entered into an employment
agreement  with him  which  provides  for an  initial  payment  to Mr.  Price of
$357,624,  an annual base salary of $400,000 in the first year,  $450,000 in the
second  year,  and  $500,000 in the third  year,  and a bonus of $200,000 in the
first year and a  performance  bonus of between  25% and 100% of his  respective
annual  base  salary for each of the second and third  years.  In  addition,  we
granted Mr. Price 25,000  restricted shares of our common stock (which vest in 3
equal annual  installments  commencing on January 1, 2001), we granted Mr. Price
an option to purchase 500,000 shares of our common stock, at a purchase price of
$12.50 per share (which vests  monthly  over 36 months,  commencing  October 30,
2000) and we  further  agreed  to grant Mr.  Price  additional  options  on each
anniversary  of the  agreement,  in an amount to be determined by the board.  We
also agreed to reimburse  Mr. Price for all expenses  incurred in  relocating to
the area and to extend him a $1,500,000  interest-deferred loan for the purchase
of a house.

     The agreement has a three-year term which will  automatically  renew for an
additional three year period unless either Mr. Price or we give the other notice
of our  intent  not to renew  the  agreement.  If we  decide  not to  renew  the
agreement,  we must pay Mr.  Price an  amount  such that our net  payment  after
deduction  of all payroll  taxes and all income  taxes at the  highest  marginal
rates  applicable to him will equal the base salary and bonus we paid him in the
third year of the agreement.  Additionally,  the exercise for any vested options
will be one year from the termination of the agreement and all unvested  options
will remain unvested and unexercisable.

     Either party can terminate the agreement on sixty days' notice. However, in
the event there is a change in control  which results in Mr.  Price's  actual or
constructive  termination,  he is entitled to a severance payment equal to twice
the  aggregate of his annual base salary and bonus  payable in the year in which
termination occurs, forgiveness of all outstanding principal and interest on the
interest-deferred  loan, acceleration of the full unvested portion of his 25,000
share stock grant and all stock options and an  additional  payment equal to Mr.
Price's  maximum  total income tax liability  applicable to the total  severance
package.  If Mr.  Price is  terminated  other than for cause,  he is entitled to
receive a severance payment equal to twice his applicable annual base salary and
bonus if he is  terminated  in the first year of the  agreement and equal to his
applicable  annual base  salary and bonus of he is  terminated  in a  subsequent
year,  forgiveness  of all  outstanding  principal  and interest on the interest
deferred-loan  and acceleration of the full unvested portion of his 25,000 share
stock grant. Additionally, if he is terminated other than for cause prior to the
second  anniversary  of the agreement,  he is entitled to an additional  payment
equal the maximum income tax liability  associated with  forgiveness of the loan
and such additional payment.

                                       15

                                 USE OF PROCEEDS

     We cannot  guarantee  that we will receive any proceeds in connection  with
this offering. We will receive the proceeds from any sale of the shares to Acqua
Wellington  as  described  in the Plan of  Distribution  but we will  receive no
proceeds from any subsequent sale of the shares by Acqua Wellington.

     We  intend  to use any  proceeds  of this  offering,  together  with  other
available funds, for the following purposes:

     o    To fund our  share of costs  associated  with our joint  venture  with
          Genzyme for the development and commercialization of Aldurazyme;

     o    To fund research and development including clinical trials, regulatory
          processes,   process   development   and   scale-up  and  start-up  of
          manufacturing   activities  for  our  other   pharmaceutical   product
          programs, including rhASB and Vibriolysin;

     o    To fund research,  development,  clinical and commercial manufacturing
          facilities, including related equipment; and

     o    To fund general corporate purposes, including working capital.

     A  portion  of the  proceeds  may  also be used to  acquire  or  invest  in
complementary  businesses or products or to obtain  rights to use  complementary
technologies.

     We may require  additional  funds in the  12-month  period  following  this
offering to accelerate product programs or to undertake new initiatives or enter
into collaborative arrangements.

     We have not  identified  precisely  the amounts we plan to spend on each of
these areas or the timing of such expenditures. Accordingly, our management will
have  significant  flexibility in applying such proceeds.  The amounts  actually
expended  for  each  purpose  may vary  significantly  depending  upon  numerous
factors,  including  the amount and timing of the proceeds  from this  offering,
progress with the regulatory  approval,  manufacturing and  commercialization of
Aldurazyme  and  rhASB and  progress  with our other  development  programs.  In
addition,  expenditures  will also depend upon the  establishment  of additional
collaborative  arrangements  with other  companies,  the  availability  of other
financing and other factors.  Pending use for these or other purposes, we intend
to invest the net  proceeds of this  offering in  short-term,  investment-grade,
interest-bearing securities.

     We  anticipate  that we will be  required to raise  substantial  additional
capital  to  continue  to  accelerate  product  programs  or  to  undertake  new
initiatives or enter into collaborative arrangements.  Additional capital may be
raised through additional public or private financing,  as well as collaborative
relationships, borrowings and other available sources. See "Risk Factors - if we
fail to obtain the capital necessary to fund our operations we will be unable to
complete our product development programs."






















                                       16

                              PLAN OF DISTRIBUTION

     On January 26, 2001, we entered into a common stock purchase agreement with
Acqua Wellington North American Equities Fund, Ltd.  pursuant to which,  subject
to the  satisfaction  of  certain  conditions,  we may  issue and sell and Acqua
Wellington  will be obligated  to  purchase,  from time to time over the next 20
months, up to an aggregate of $50,000,000 of our common stock.

     At our discretion,  we may present Acqua  Wellington with draw down notices
from time to time,  provided  that  there  must be at least  five  trading  days
between the end of each pricing  period and the next draw down,  requiring  that
Acqua  Wellington  purchase  shares of our common stock.  For each draw down, we
will  determine  the minimum sale price per share and the total dollar amount of
each draw down, subject to a limit of between $500,000 and $4,000,000 determined
by the minimum  sale price of the draw down.  Over a 20 trading day period,  for
each trading day the volume weighted  average price for our common stock exceeds
the minimum purchase price, Acqua Wellington will be obligated to purchase a pro
rata  portion  of the total draw down  amount at a price per share  equal to the
volume weighted  average price of our common stock less a discount of between 4%
to 6%.

     Additionally,  at our  discretion,  in connection with each any down we may
issue Acqua  Wellington  call options of up to the amount of the draw down.  The
call  options  give Acqua  Wellington  the  right,  but not the  obligation,  to
purchase an additional amount of our common stock concurrent with the draw down.
Acqua Wellington may exercise all or any unexercised portion of these options at
any time  during the  pricing  period of the draw down and for a purchase  price
equal to the volume  weighted  average  price of our common  stock on the day of
exercise less a discount of 4% to 6%.

     All of the shares  purchased under a draw down and upon the exercise of any
related call options will be settled on the second  trading day after the end of
the related pricing period. Prior to each settlement,  we will file a prospectus
supplement that describes the number of shares being purchased and the price per
share.  The  aggregate  amount of common  stock  that Acqua  Wellington  will be
required  to  purchase  from us will not  exceed an  aggregate  of  $50,000,000.
Additionally,  Acqua  Wellington  will have no obligation to purchase our common
stock if the volume weighted  average trading price of our common stock is below
$7.00 per share.

     If on the ten month  anniversary of the stock purchase  agreement,  we have
not  requested  draw downs and granted call  options in an  aggregate  amount of
$4,500,000 we will be required to either pay Acqua  Wellington a fee of not more
than $300,000 or to issue to Acqua Wellington warrants to purchase not more than
300,000 shares of our common stock, at Acqua Wellington's discretion.

     Pursuant to the purchase  agreement,  Acqua Wellington may resell shares of
our  common  stock at any  time,  in such  manner  and at such  prices as it may
determine.  These  sales  of  common  stock  may  occur  from  time  to  time in
transactions  on the Nasdaq  National  Market (or any exchange  where the common
stock  is then  listed),  in  negotiated  transactions,  or  otherwise,  or by a
combination  of these methods,  at fixed prices which may be changed,  at market
prices at the time of sale, at prices  related to market prices or at negotiated
prices.  Acqua  Wellington may effect these  transactions  by selling the common
stock to or through broker-dealers,  who may receive compensation in the form of
discounts, concessions or commissions from Acqua Wellington or the purchasers of
the common  stock for whom the  broker-dealer  may act as an agent or to whom it
may sell the  common  stock as a  principal,  or  both.  The  compensation  to a
particular  broker-dealer may be in excess of customary commissions.  Neither we
nor Acqua Wellington can presently estimate the amount of such compensation.

     Broker-dealers  may agree with Acqua  Wellington to sell a specified number
of shares of our  common  stock at a  stipulated  price per share,  and,  to the
extent  such a  broker-dealer  is  unable  to do so  acting  as agent  for Acqua
Wellington,  to  purchase  as  principal  any unsold  common  stock at the price
required  to  fulfill  the   broker-dealer   commitment  to  Acqua   Wellington.
Broker-dealers  who acquire common stock as principal may thereafter  resell the
common stock from time to time in  transactions  (which may involve  crosses and
block   transactions   and  which  may  involve   sales  to  and  through  other
broker-dealers,  including  transactions of the nature  described  above) in the
over-the-counter  market,  in negotiated  transactions  or otherwise,  at market
prices prevailing at the time of sale or at negotiated prices, and in connection
with such resales may pay to or receive from the purchasers of such common stock
commissions computed as described above.

     Acqua Wellington may be deemed an  "underwriter"  within the meaning of the
Securities Act in connection  with the sale of the common stock offered  hereby.
Broker-dealers  who act in connection with the sale of the common stock may also
be deemed to be  underwriters.  Profits on any  resale of the common  stock as a
principal by such broker-dealers and any commissions received by such

                                       17

broker-dealers may be deemed to be underwriting  discounts and commissions under
the Securities  Act. Any  broker-dealer  participating  in such  transactions as
agent may receive  commissions  from Acqua Wellington (and, if they act as agent
for the purchaser of our common stock, from such purchaser).

     The  common  stock  offered  hereby  is being  registered  pursuant  to our
contractual  obligations  with Acqua  Wellington,  and we have agreed to pay the
costs of  registering  the shares  hereunder.  We have also agreed to  reimburse
Acqua  Wellington's  costs and expenses  incurred in  connection  with the stock
purchase  agreement,  including fees,  expenses and disbursements of counsel for
Acqua  Wellington for the  preparation  of the stock purchase  agreement up to a
maximum of $50,000,  and all  reasonable  fees incurred in  connection  with any
amendment,  modification  or waiver,  to or  enforcement  of the stock  purchase
agreement.

     In the stock purchase  agreement with Acqua  Wellington,  we have agreed to
indemnify and hold harmless Acqua  Wellington and each person who controls Acqua
Wellington,  against  certain  liabilities,   including  liabilities  under  the
Securities  Act,  which  may be based  upon,  among  other  things,  any  untrue
statement  or alleged  untrue  statement  of a material  fact or any omission or
alleged  omission  of a  material  fact  contained  in  any  prospectus  or  any
prospectus  supplement,   unless  made  or  omitted  in  reliance  upon  written
information provided to us by Acqua Wellington.

liabilities and expenses incurred by such persons in connection with claims made
by reason of their being such a director or officer. Pursuant to this authority,
the Registrant has entered into an indemnification  agreement with each director
and  executive  officer,   whereby  the  Registrant  has  agreed  to  cover  the
indemnification obligations.

     The  Registrant  maintains  director's  and officer's  insurance  providing
indemnification  against  certain  liabilities  for certain of the  Registrant's
directors, officers, affiliates, partners or employees.

     The  indemnification   provisions  in  the  Registrant's  Bylaws,  and  the
indemnification agreements entered into between the Registrant and its directors
and executive officers,  may be sufficiently broad to permit  indemnification of
the Registrant's officers and directors for liabilities arising under the Act.

     Reference is made to the following documents incorporated by reference into
this  Registration  Statement  regarding  relevant  indemnification   provisions
described above and elsewhere herein:  (1) the Amended and Restated  Certificate
of  Incorporation,  filed as Exhibit  3.1B to  Registrant's  Amendment  No. 2 to
Registration  Statement  on Form S-1  filed  with the  Securities  and  Exchange

Agreement  entered  into  by the  Registrant  with  each  of its  directors  and

ITEM 17.  UNDERTAKINGS

     Insofar as indemnification for liabilities arising under the Securities Act
of 1933, may be permitted to directors, officers, and controlling persons of the
Registrant  pursuant to the  provisions  described in Item 15 or otherwise,  the
Registrant  has been advised that in the opinion of the  Securities and Exchange
Commission,  such  indemnification  is against public policy as expressed in the
Act,  and  is,  therefore,   unenforceable.  In  the  event  that  a  claim  for
indemnification  against  such  liabilities  (other  than  the  payment  by  the
Registrant of expenses incurred or paid by a director,  officer,  or controlling
person of the  Registrant  in the  successful  defense  of any action  suit,  or
proceeding) is asserted by such  director,  officer,  or  controlling  person in
connection with the securities being registered,  the Registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit  to a  court  of  appropriate  jurisdiction  the  question  whether  such
indemnification  by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

         The undersigned Registrant hereby undertakes:

                  (1) To file,  during any  period in which  offers or sales are
                  being made  pursuant to this  registration  statement:  (i) to
                  include any  prospectus  required  by Section  10(a)(3) of the
                  Securities Act of 1933;  (ii) to reflect in the prospectus any
                  facts  or  events  arising  after  the  effective  date of the
                  registration  statement  (or the  most  recent  post-effective
                  amendment  thereof)  which,  individually or in the aggregate,
                  represent a fundamental change in the information set forth in
                  the registration statement. Notwithstanding the foregoing, any
                  increase or decrease in volume of  securities  offered (if the
                  total dollar value of securities offered would not exceed that
                  which was  registered)  and any deviation from the low or high
                  end of the estimated  maximum  offering range may be reflected
                  in the form of prospectus  filed with the Commission  pursuant
                  to Rule 424(b) if, in the aggregate, the changes in volume and
                  price  represent  no  more  than a 20  percent  change  in the
                  maximum aggregate offering price set forth in the "Calculation
                  of  Registration  Fee"  table  in the  effective  registration
                  statement;  (iii) to include  any  material  information  with
                  respect to the  distribution  not previously  disclosed in the
                  registration   statement  or  any  material   change  to  such
                  information in the registration statement;

                  (2) That, for the purpose of determining  any liability  under
                  the Securities Act of 1933, each such post-effective amendment
                  shall be deemed to be a new registration statement relating to
                  the  securities  offered  therein,  and the  offering  of such
                  securities at that time shall be deemed to be the initial bona
                  fide offering thereof; and

                  (3) To remove from  registration by means of a  post-effective
                  amendment any of the securities  being registered which remain
                  unsold at the termination of the offering.

                                      II-2


     The  undersigned   Registrant  hereby  undertakes  that,  for  purposes  of
determining  any liability  under the Securities Act of 1933, each filing of the
Registrant's  annual  report  pursuant to section  13(a) or section 15(d) of the
Securities  Exchange  Act of  1934  that is  incorporated  by  reference  in the
registration  statement  shall  be  deemed  to be a new  registration  statement
relating to the securities offered therein,  and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

     The undersigned  Registrant undertakes that: (1) for purpose of determining
any liability under the Securities Act of 1933, the information omitted from the
form of prospectus filed as part of the registration  statement in reliance upon
Rule  430A and  contained  in the  form of  prospectus  filed by the  Registrant
pursuant to Rule 424(b) (1) or (4) or 497(h) under the  Securities  Act shall be
deemed to be part of the  registration  statement as of the time it was declared
effective;  and (2) for the  purpose  of  determining  any  liability  under the
Securities Act of 1933,  each  post-effective  amendment that contains a form of
prospectus  shall be deemed to be a new registration  statement  relating to the
securities  offered  therein,  and the offering of such  securities at that time
shall be deemed to be the initial bona fide offering thereof.
