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.

We develop  enzyme  therapies to treat  serious,  life-threatening  diseases and
conditions.  We leverage  our  expertise  in enzyme  biology to develop  product
candidates  for the treatment of genetic  diseases,  including MPS I, MPS VI and
PKU, as well as other care situations such as cardiovascular surgery and serious
burns.  Our  product  candidates  address  markets  for  which no  products  are
currently  available or where current  products have been  associated with major
deficiencies.  We focus on conditions  with  well-defined  patient  populations,
including genetic diseases, which require chronic therapy.

Our lead product candidate,  Aldurazyme(TM),  which recently completed a Phase 3
trial, is being developed for the treatment of  Mucopolysaccharidosis  I (MPS I)
disease. MPS I is a debilitating and life-threatening  genetic disease caused by
the deficiency of (alpha)-L-iduronidase, an enzyme responsible for breaking down
certain  carbohydrates.  MPS I is a progressive  disease that afflicts  patients
from birth and frequently leads to severe disability and early death.  There are
currently  no drugs on the market for the  treatment  of MPS I.  Aldurazyme  has
received  both fast  track  designation  from the  United  States  Food and Drug
Administration  (FDA) and orphan drug  designation for the treatment of MPS I in
the United  States  and in the  European  Union.  We are  developing  Aldurazyme
through a joint venture with Genzyme Corporation. In collaboration with Genzyme,
we  completed a  double-blinded,  placebo-controlled  Phase 3 clinical  trial of
Aldurazyme in August 2001. On November 2, 2001,  we announced  positive  results
from this trial.

Our joint venture submitted a Marketing  Authorization  Application (MAA) to the
European  Medicines  Evaluation  Agency (or EMEA) on March 1, 2002. The EMEA has
accepted  our MAA and  validated  that it is complete  and ready for  scientific
review.  Accordingly,  the EMEA's Committee for Proprietary  Medicinal  Products
(CPMP)  will now  evaluate  the  application  to  determine  whether  to approve
Aldurazyme  for the  treatment of MPS I in all 15 member  states of the European
Union.  Norway  and  Iceland  also  participate  in the CPMP but have a separate
approval process.

On April 15, 2002,  Genzyme and we announced  that the joint  venture  filed the
first portion of a "rolling"  Biologics  License  Application (BLA) with the FDA
for approval to market  Aldurazyme in the United States. We plan to complete the
BLA filing in the third quarter of this year. The BLA will include six months of
data from the  ongoing  open-label  Phase 3  extension  study in addition to the
six-month  data  from  the  placebo-controlled  portion  of the  Phase 3  trial.
Patients  from  both the  treatment  and  placebo  arms of the Phase 3 trial had
received at least six months of weekly  Aldurazyme  infusions in the  open-label
extension  study as of February 8, 2002.  Genzyme and we  anticipate  a response
from the FDA regarding the application to market Aldurazyme in the United States
during the first half of 2003.

We are developing our second product candidate,  Neutralase(TM), for reversal of
anticoagulation by heparin in patients  undergoing Coronary Artery Bypass Graft,
or CABG,  surgery and angioplasty.  We acquired rights to Neutralase through our
acquisition of the pharmaceutical assets of IBEX Technologies Inc. in the fourth
quarter  of 2001.  Heparin  is a  carbohydrate  drug  commonly  used to  prevent
coagulation,   or  blood  clotting,  during  certain  types  of  major  surgery.
Neutralase is a  carbohydrate-modifying  enzyme that cleaves  heparin,  allowing
coagulation  of blood and aiding  patient  recovery  following  CABG surgery and
angioplasty.  Based on data from previous trials,  we plan to initiate a Phase 3
trial in CABG surgery in 2002.

In addition to Aldurazyme and Neutralase,  we are developing other  enzyme-based
therapeutics for the treatment of a variety of diseases and conditions. In 2001,
we announced results from a Phase 1 trial of Aryplase(TM)  (formerly referred to
as rhASB) for the treatment of MPS VI, another  seriously  debilitating  genetic
disease. Based on data from this previous trial, we initiated a Phase 2 trial of
Aryplase  in  March  of  2002.  The  primary   objective  of  this   open-label,
multi-national  Phase 2 clinical trial will be to evaluate the efficacy,  safety
and  pharmacokinetics  of weekly intravenous  infusions of Aryplase in 10 MPS VI
patients.
                                       1


We are  also  developing  Vibrilase(TM)  (formerly  referred  to as  Vibriolysin
Topical),  a topical  enzyme  product for use in removing  burned skin tissue in
preparation for skin grafting or other therapy.  We initiated a Phase 1 clinical
trial of  Vibrilase  in the United  Kingdom in the fourth  quarter of 2001,  and
expect to begin a Phase 2  clinical  trial in either  the  United  States or the
United Kingdom  following the completion of this Phase 1 trial. In addition,  we
are pursuing  preclinical  development  of other enzyme  product  candidates for
genetic and other diseases.

Recent Developments

On March 21, 2002, we acquired Synapse Technologies Inc. Synapse owns the rights
to certain patented and proprietary  technology  which,  based on the results of
preclinical  trials, has the potential to deliver  therapeutic enzymes and other
drugs  across  the  blood-brain  barrier  by  means of  traditional  intravenous
injections.  Under  the  terms  of  the  agreement,  we  purchased  100%  of the
outstanding shares of Synapse for approximately $10.2 million payable in 885,242
shares of our common stock. We also may make future contingent payments of up to
approximately  $6 million.  These payments are payable in cash or stock,  at our
option.

On February 25, 2002, we decided to close the analytics product catalog business
of our  wholly-owned  subsidiary,  Glyko,  Inc. The majority of the Glyko,  Inc.
employees  will be  incorporated  into  our  pharmaceutical  business  and  such
employees will continue to provide necessary  analytic and diagnostic support to
our therapeutic products. Certain operating assets of Glyko, Inc. may be offered
for sale.

On February 7, 2002, we announced that we had reached a definitive  agreement to
acquire all of the  outstanding  capital stock of Glyko  Biomedical  Ltd. (GBL).
GBL's principal asset is its 21.3% ownership  interest in our common stock.  GBL
owns  approximately  11.4 million shares of our common stock. Under the terms of
the acquisition agreement,  GBL's common shareholders will receive approximately
11.4 million shares of our common stock in exchange for all of GBL's outstanding
common shares. There will be no net effect on the number of shares of our common
stock outstanding,  as we plan to retire the existing shares of our common stock
currently held by GBL upon closing.

                           FORWARD LOOKING STATEMENTS

This prospectus contains forward looking statements.  These statements relate to
future events or our future financial  performance.  We have identified  forward
looking  statements  in this  prospectus  using  words  such  as  "anticipates",
"believes,"  "could,"   "estimates,"   "expects,"   "intends,"  "may,"  "plans,"
"potential,"  "predicts,"  "should,"  or "will" or the negative of such terms or
other comparable terminology.  These statements are based on our beliefs as well
as  assumptions  we made using  information  currently  available to us. Because
these  statements  reflect our current views  concerning  future  events,  these
statements  involve  risks,   uncertainties,   and  assumptions.   These  risks,
uncertainties, assumptions and other factors, including the risks outlined under
"Risk Factors," that may cause our or our industry's  actual results,  levels of
activity,  performance or  achievements  to be materially  different from future
results,  levels of actual  activity,  performance or achievements  expressed or
implied by such forward looking statements.

Although we believe  that the  expectations  reflected  in the  forward  looking
statements  are  reasonable,  we  cannot  guarantee  future  results,  levels of
activity, performance or achievements. Moreover, neither we nor any other person
assumes responsibility for the accuracy and completeness of such statements.  We
are under no duty to update any of the forward looking statements after the date
of this prospectus to conform such statements to actual results, unless required
by law.

                                  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,  to evaluate 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
product  candidates.  As of December 31, 2001, we had an accumulated  deficit of
approximately $148.1 million. We expect to continue to operate at a net loss for
the  foreseeable  future.  Our future  profitability  depends  on our  receiving
regulatory  approval of our product  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.

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

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 manufacturing
         processes, including quality systems and to build or acquire
         manufacturing capabilities;

o        the time and cost necessary to respond to technological and market
         developments; and

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

o        additional contracts for product manufacturing.

We believe that our cash, cash equivalents and short term investment  securities
balances  at December  31, 2001 will be  sufficient  to meet our  operating  and
capital  requirements through 2003. These estimates are 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 and our operating results will be
adversely affected.

We must obtain regulatory approval before marketing or selling our drug products
in the U.S.  and in  foreign  jurisdictions.  In the U.S.,  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  products  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 will be  required,  and the results of the
studies and trials are highly uncertain.

     As part of the regulatory  approval  process,  we must conduct,  at our own
expense, preclinical studies in the laboratory on animals and clinical trials on
humans for each drug product.  We expect the number of  preclinical  studies and
clinical trials that the regulatory authorities 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 drug products.  Additional factors that can cause delay or termination of
our clinical trials include:

o        slow or insufficient patient enrollment;

o        slow recruitment of, and completion of necessary institutional
         approvals at clinical sites;

                                       4


o        longer treatment time required to demonstrate efficacy;

o        lack of sufficient supplies of the product candidate;

o        adverse medical events or side effects in treated patients;

o        lack of effectiveness of the product candidate being tested; and

o        regulatory requests for additional clinical trials.

Typically,  if a drug product is intended to treat a chronic disease,  as is the
case with some of the product candidates we are developing,  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 May 2001, we completed a 24-month patient evaluation for the initial clinical
trial of our lead drug product,  Aldurazyme,  for the treatment of MPS I. Two of
the  original  ten  patients  enrolled in this trial died in 2000.  One of these
patients  received 103 weeks of Aldurazyme  treatment and the other received 137
weeks of treatment.  One of the original  forty-five  patients who completed the
Phase 3 clinical trial died after 16 weeks of the Phase 3 extension  study.  One
patient  treated  under a  single-patient  use  protocol  died after 31 weeks of
Aldurazyme   treatment.   Based  on  medical  data   collected   from   clinical
investigative  sites,  none of these cases  directly  implicated  treatment with
Aldurazyme as the cause of death. If cases of patient complications or death are
ultimately  attributed to Aldurazyme,  our chances of commercializing  this drug
would be seriously compromised.

The fast track designation for our product candidates may not actually lead to a
faster review process.

Although  Aldurazyme  and Aryplase  have obtained  fast track  designations,  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 process  qualification  batches to final  specifications  under cGMP
controls for each of our drug products before the marketing  applications can be
approved.   Although  we  have  completed  process   qualification  batches  for
Aldurazyme,  these batches may be rejected by the regulatory authorities, and we
may be unable to  manufacture  the process  qualification  batches for our other
products or pass the inspections in a timely manner, if at all.

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

As part of our  business  strategy,  we intend to develop some drugs that may be
eligible  for FDA and  European  Community  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 the United  States.  The company that first
obtains 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  Community with a
ten-year period of market exclusivity.

                                       5


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.

Even though we have obtained orphan drug  designation for certain of our product
candidates 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,  if we do,  that  exclusivity  would
effectively  protect  the product  from  competition.  Orphan  drug  designation
neither  shortens the development  time or regulatory  review time of a drug nor
gives the drug any advantage in the regulatory review or approval process.

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

Two of our lead drug candidates,  Aldurazyme and Aryplase,  target diseases with
small  patient  populations.  As  a  result,  our  per-patient  prices  must  be
relatively  high  in  order  to  recover  our  development   costs  and  achieve
profitability.  Aldurazyme  targets  patients  with MPS I and  Aryplase  targets
patients with MPS VI. 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  payers,  there  would be no  commercially  viable  markets  for our
products.

The  course  of  treatment  for  patients  with MPS I using  Aldurazyme  and for
patients  with MPS VI using  Aryplase  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  or
Aryplase without reimbursement from third-party payers.

Third-party  payers,  such  as  government  or  private  health  care  insurers,
carefully  review  and  increasingly  challenge  the prices  charged  for drugs.
Reimbursement  rates from private  companies vary  depending on the  third-party
payer,  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  payers will pay for the costs of our drugs.
Even if we are able to obtain  reimbursement from third-party  payers, 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  payers 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
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.

                                       6


Where  appropriate,  we  seek  patent  protection  for  certain  aspects  of our
technology.  Patent  protection  may not be available for some of the enzymes we
are  developing.  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 have been published and are believed to be
in the public domain. The composition and genetic sequences of other MPS enzymes
that 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 broad composition-of-matter  patents, other forms of
patent  protection  or orphan  drug  status may  provide  us with a  competitive
advantage.  As a result of these  uncertainties,  investors  should  not rely on
patents as a means of protecting our product candidates, including Aldurazyme.

We own or license  patents  and patent  applications  to certain of our  product
candidates.  However,  these patents and patent  applications  do not ensure the
protection of our intellectual property for a number of other reasons, including
the following:

o        We do not know whether our patent applications will result in issued
         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. In litigation, a competitor could claim that our issued
         patents are not valid for a number of reasons. If a court agrees, we
         would lose that patent. 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. Management would spend less time and resources on
         developing products, which could increase our research and development
         expense and delay product programs.

o        Receipt of a patent 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 the following:

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 crosslicenses 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 two patents that
relate to  (alpha)-L-iduronidase.  If we are not able to successfully  challenge
these patents, we may be prevented from producing Aldurazyme unless and until we
obtain a license.

The United States Patent and Trademark  Office  recently issued two patents that
include  composition  of  matter  and  method  of  use  claims  for  recombinant
(alpha)-L-iduronidase.   Our  lead  drug  product,   Aldurazyme,   is  based  on
recombinant (alpha)-L-iduronidase.  We believe that these patents are invalid on
a number  of  grounds.  A  corresponding  patent  application  was  filed in the
European   Patent  Office   claiming   composition  of  matter  for  recombinant
(alpha)-L-iduronidase,  and it was  rejected  over prior art and  withdrawn  and
cannot be re-filed.  Nonetheless, under U.S. law, issued patents are entitled to
a  presumption  of  validity,  and our  challenges  to the U.S.  patents  may be
unsuccessful.  Even if we are successful,  challenging  the U.S.  patents may be
expensive,  require our management to devote significant time to this effort and
may delay commercialization of Aldurazyme in the United States.

The patent  holder has granted an  exclusive  license for  products  relating to
these  patents  to one of our  competitors.  If we are  unable  to  successfully
challenge  the  patents,  we may be unable to produce  Aldurazyme  in the United
States unless we can obtain a sublicense 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 other  enzyme-based  products to the marketing of our initial
drug product,  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.

If the joint venture is terminated for breach, the non-breaching  party 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
the breaching  party's  interest in the joint  venture.  If we are the breaching
party,  we would  lose our rights to  Aldurazyme  and the  related  intellectual
property and regulatory  approvals.  If the joint venture is terminated  without
cause,  the  non-terminating  party would have the option,  exercisable  for one
year,  to buy out the  terminating  party's  interest  in the joint  venture and
obtain all rights to Aldurazyme exclusively.  In the 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.

                                       8


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.

Although we have successfully manufactured Aldurazyme at commercial scale within
our cost parameters, we cannot guarantee that we will be able to manufacture any
other drug product successfully with a commercially viable process or at a scale
large enough to support  their  respective  commercial  markets or at acceptable
margins.

Our  manufacturing  processes  may  not  meet  initial  expectations  and we may
encounter  problems with any of the following  measurements of performance if we
attempt to increase the scale or size or improve the commercial viability of our
manufacturing processes:

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

o        schedule;

o        reproducibility;

o        production yields;

o        purity;

o        costs;

o        quality control and assurance systems;

o        shortages of qualified personnel; and

o        compliance with regulatory requirements.

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 becomes  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.

The  availability  of suitable  contract  manufacturing  at scheduled or optimum
times is not  certain.  The  cost of  contract  manufacturing  is  greater  than
internal  manufacturing  and therefore our  manufacturing  processes  must be of
higher productivity to yield equivalent margins.

                                       9


The manufacture of Neutralase  involves the fermentation of a bacterial species.
We have never used a  bacterial  production  process for the  production  of any
commercial product.  IBEX Technologies Inc., from which we acquired  Neutralase,
had contracted  with a third party for the manufacture of the Neutralase used in
prior clinical trials.

We have built-out  approximately 51,800 square feet at our Novato facilities for
manufacturing  capability for Aldurazyme and Aryplase  including related quality
control laboratories,  materials  capabilities,  and support areas. We expect to
add additional  capabilities in stages over time, which could create  additional
operational complexity and challenges.  We expect that the manufacturing process
of all of our new drug products, including Aryplase and Neutralase, will require
significant  time and resources before we can begin to manufacture them (or have
them  manufactured by third parties) in commercial  quantity at acceptable cost.
Even if we can  establish  the  necessary  capacity,  we cannot be certain  that
manufacturing  costs will be  commercially  reasonable,  especially  if contract
manufacturing is employed or 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 makeup;

o        improving the manufacturing 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 that is used to
produce an enzyme or other  protein that it would not have  otherwise  produced.
The  development of a stable,  high production cell line for any given enzyme is
difficult, 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 create 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  capabilities  either  by  developing  our own 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.

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 products.

With our  acquisition  of  Neutralase  from IBEX  Technologies  Inc., we have an
enzyme product that has a significantly larger potential patient population than
Aldurazyme  and  Aryplase  and will be  marketed  and sold to  different  target
audiences with different therapeutic and financial  requirements and needs. As a
result,  we  will  be  competing  with  other   pharmaceutical   companies  with
experienced  and  well-funded  sales and marketing  operations  targeting  these
specific physician and institutional audiences. We may not be able to create our
own sales and  marketing  force or of a size that would allow us to compete with
these  other  companies.  If we elect to enter into  third-party  marketing  and
distribution  agreements in order to sell into these markets, we may not be able
to enter into these  agreements  on  acceptable  terms,  if at all. If we cannot
compete  effectively in these specific physician and institutional  markets,  it
would adversely affect sales of Neutralase.

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

                                       10


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  that  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 in the U.S. and
ten years in the European  Union.  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 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.

If we do not achieve milestones as expected, our stock price may decline.

For planning  purposes,  we estimate the timing of the accomplishment of various
scientific,  clinical, regulatory and other milestones, such as the commencement
or completion of scientific  studies and clinical  trials and the  submission of
regulatory  filings.  These  estimates,  some  of  which  are  included  in this
prospectus,  are based on a variety of  assumptions.  The actual timing of these
milestones can vary  dramatically  compared to our estimates,  in many cases for
reasons beyond our control.

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 and/or foreign  government  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 Emil D. Kakkis,  M.D., Ph.D., our
Senior Vice President of Scientific Affairs or Christopher M. Starr,  Ph.D., our
Senior Vice President for Research and  Development,  could be detrimental to us
if we cannot recruit suitable  replacements in a timely manner. While Mr. Price,
Dr. Kakkis 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.

                                       11


If we fail  to  effectively  integrate  the  recently  acquired  Neutralase  and
Phenylase programs and those acquired from Synapse  Technologies,  Inc. into our
current  operations,  the efficient execution of these product programs could be
delayed and our  operating  and  research  and  development  expenditures  could
increase beyond anticipated levels.

Our recent  acquisition  of assets from IBEX  Technologies  Inc.,  including the
Neutralase and Phenylase product programs, and from Synapse Technologies,  Inc.,
will need to be  integrated  with our  current  operations.  This  will  include
several  technical  and  administrative   challenges,   including  managing  the
information transfer,  integrating certain of our former technical staff members
at IBEX and Synapse  into our research and  development  structure  and managing
multiple  operations  in  different  countries.  If we do  not  accomplish  this
integration  effectively,  our programs  could be delayed and our  operating and
research and development  expenditures could increase beyond anticipated levels.
Additionally,  the integration  could require a significant time commitment from
our senior management.

Changes in methods of treatment of disease could reduce demand for our products.

Even if our drug products are approved, doctors must use treatments that require
using those products. If doctors elect a different course of treatment from that
which includes our drug products, this decision would reduce demand for our drug
products.

Examples  include the potential use in the future of effective  gene therapy for
the treatment of genetic diseases.  The use of gene therapy could  theoretically
reduce or  eliminate  the use of enzyme  replacement  therapy  in MPS  diseases.
Sometimes,  this change in treatment method can be caused by the introduction of
other  companies'  products or the  development of new  technologies or surgical
procedures  which may not directly  compete with ours, but which have the effect
of changing how doctors  decide to treat a disease.  For example,  Neutralase is
being  developed  for heparin  reversal  in CABG  surgery.  It is possible  that
alternative  non-surgical  methods of treating heart disease could be developed.
If so, then the demand for Neutralase would likely decrease.

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 Aryplase  and  Vibrilase.  We may be subject to claims in  connection
with our current  clinical  trials for  Aldurazyme,  Aryplase and  Vibrilase for
which the joint venture's or our insurance coverages are not adequate. We cannot
be certain that if Aldurazyme,  Aryplase or Vibrilase receives FDA approval, the
product  liability  insurance  the  joint  venture  or we will need to obtain in
connection with the commercial  sales of Aldurazyme,  Aryplase or Vibrilase 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.

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, Neutralase, Aryplase and our other lead drug
         products through the regulatory process, especially regulatory actions
         in the United States related to Aldurazyme;

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

                                       12


o        government regulatory action affecting our drug products or our
         competitors' drug products in both the United States and foreign
         countries;

o        developments or disputes concerning patent or proprietary rights;

o        general market conditions and fluctuations for the emerging growth and
         biopharmaceutical market sectors;

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, which may
         cause the market price of our common stock to fluctuate; and

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; and

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.

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 28% of the outstanding  shares
of our  common  stock.  Glyko  Biomedical  Ltd.  owns  approximately  22% 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 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.

We are 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.

                                 USE OF PROCEEDS

We will not receive any of the proceeds from the sale of the shares  offered and
sold for the  account of the  selling  stockholder.  However,  the  shares  were
originally  purchased  by the  stockholder  with  proceeds  of a loan  from  us.
Pursuant  to the  terms  of a  security  agreement  securing  the  stockholder's
obligations  under this loan, a majority of the proceeds  from the sale of these
shares will be used to repay this loan.

The selling  stockholder  will not pay any of the expenses  that are incurred in
connection with the registration of the shares, but he will pay all commissions,
discounts and any other  compensation  to any securities  broker dealers through
whom he sells any of the shares.

                               SELLING STOCKHOLDER

The  following  table  sets  forth  the  name of the  selling  stockholder,  the
aggregate number of shares of common stock beneficially owned by him as of April
15, 2002,  and the aggregate  number of shares of common stock that he may offer
and sell pursuant to this prospectus.  Because the selling stockholder may offer
all or a portion of the shares of common stock offered by this prospectus at any
time and from time to time after the date hereof, no estimate can be made of the
number of shares that he may retain upon  completion of this offering.  However,
assuming  the  selling  stockholder  sells  all of the  shares  offered  by this
prospectus,  after completion of this offering, the selling stockholder will own
approximately 2.0% of the shares of our common stock outstanding.

The shares to be sold in this offering  represent a portion of the shares issued
to the selling  stockholder at the time we were formed.  At that time, we loaned
the  selling   stockholder  the  money  to  purchase  the  shares.  The  selling
stockholder  was our chairman  and chief  executive  officer from our  inception
until  October  of 2000.  He  continues  to serve  as a member  of our  board of
directors.  The majority of the  proceeds  from the sale of these shares will be
used to repay this loan.

In the following table, we have calculated  shares of common stock  beneficially
owned based upon 53,369,774  shares of our common stock outstanding on April 15,
2002, together with options,  warrants or other convertible  securities that are
exercisable,  or other rights to acquire  common stock,  within 60 days of April
15,  2002 by the  selling  stockholder.  Under the rules of the  Securities  and
Exchange  Commission,  beneficial ownership includes shares over which the named
stockholder  exercises  voting  and/or  investment  power.  We believe  that the
selling  stockholder  has sole voting and  investment  power with respect to all
shares he beneficially owns, subject to applicable  community property laws. The
information  with  respect to  beneficial  ownership of common stock held by the
selling  stockholder  is based upon  information as supplied or confirmed by the
selling stockholder.

                              PLAN OF DISTRIBUTION

We are  registering  the  shares  of  common  stock  offered  for  sale  by this
prospectus  on  behalf  of the  selling  stockholder.  As used in this  section,
"selling stockholder" includes donees,  pledgees,  distributees,  transferees or
other  successors-in-interest,  including,  without limitation, their respective
affiliates,  members and limited or general partners,  all of which are referred
to as a group below as  transferees,  or certain  counterparties  to  derivative
transactions   with  the  selling   stockholder  or  transferees.   The  selling
stockholder will act independently of us in making decisions with respect to the
timing,  manner and size of each sale. We will pay all costs,  expenses and fees
in connection with the registration of the shares. The selling  stockholder will
pay all brokerage commissions,  underwriting  discounts,  commissions,  transfer
taxes and other similar selling  expenses,  if any,  associated with the sale of
the shares of common stock by him.

Shares of common stock may be sold by the selling  stockholder from time to time
in one or more types of transactions  (which may include block  transactions) on
the Nasdaq  National Market or on any other market on which our common stock may
from time to time be  trading,  in the  over-the-counter  market,  in  privately
negotiated  transactions,  through put or call options transactions  relating to
the shares, through short sales of such shares, or a combination of such methods
of sale, at market prices prevailing at the time of sale, fixed prices,  varying
prices  determined  at the time of sale or at  negotiated  prices.  The  selling
stockholder  will have the sole  discretion  not to accept any purchase offer or
make any sale of shares if he deems the purchase price to be  unsatisfactory  at
any  particular  time.  Such  transactions  may or may not  involve  brokers  or
dealers.  To the best of our knowledge,  the selling stockholder has not entered
into any agreements,  understandings  or arrangements  with any  underwriters or
broker-dealers regarding the sale of his securities, nor is there an underwriter
or coordinating  broker acting in connection with the proposed sale of shares of
common stock offered by this prospectus;  however,  the selling  stockholder may
enter into  agreements,  understandings  or arrangements  with an underwriter or
broker-dealer regarding the sale of his shares in the future.

The selling stockholder may effect such transactions by selling shares of common
stock directly to purchasers or to or through  broker-dealers,  which may act as
agents or principals,  or other agents.  Such broker-dealers or other agents may
receive compensation in the form of discounts,  concessions, or commissions from
the selling  stockholders  and/or the  purchasers  of shares of common stock for
whom such  broker-dealers or other agents may act as agents or to whom they sell
as principal,  or both (which  compensation as to a particular  broker-dealer or
other  agent might be in excess of  customary  commissions).  Market  makers and
block  purchasers  purchasing the shares will do so for their own account and at
their own risk. It is possible that the selling stockholder will attempt to sell
shares  of  common  stock  in  block  transactions  to  market  makers  or other
purchasers at a price per share which may be below the then market price.

The selling  stockholder and any brokers,  dealers or agents that participate in
connection  with the sale of  shares  of  common  stock  might be  deemed  to be
"underwriters" within the meaning of the Securities Act of 1933 (the "Securities
Act"), and any commissions  received by such brokers,  dealers or agents and any
profit on the resale of the shares sold by them while acting as principals might
be deemed to be underwriting  discounts or commissions under the Securities Act.
We have agreed to indemnify the selling stockholder against certain liabilities,
including  liabilities arising under the Securities Act. The selling stockholder
may agree to indemnify any agent,  dealer,  broker-dealer  or  underwriter  that
participates  in  transactions  involving  sales of the  shares of common  stock
offered  pursuant to this  prospectus  against  certain  liabilities,  including
liabilities arising under the Securities Act.

Because the selling stockholder may be deemed to be an "underwriter"  within the
meaning of the Securities  Act, the selling  stockholder  will be subject to the
prospectus delivery requirements of the Securities Act and the rules promulgated
thereunder and they may be subject to certain  statutory  liabilities  under the
Securities  Act,  including,  but not limited to,  Sections 11, 12 and 17 of the
Securities  Act and Rule 10b-5 under the  Securities  Exchange  Act of 1934 (the
"Securities  Exchange Act"). In addition,  the selling stockholder and any other
person participating in the offering will be subject to applicable provisions of
the Securities Exchange Act and the rules and regulations thereunder,  including
Regulation M under the  Securities  Exchange Act,  which may limit the timing of
purchases and sales.  These  restrictions  may affect the  marketability  of the
common stock and the ability of any person to engage in market-making activities
with respect to the common stock.

                                       15


To comply  with the  securities  laws of  certain  jurisdictions,  the shares of
common  stock  offered  by this  prospectus  may need to be offered or sold only
through  registered  or licensed  brokers or dealers.  In  addition,  in certain
jurisdictions, the shares of common stock may not be offered or sold unless they
have been  registered  or qualified  for sale or an  exemption is available  and
complied with.

If the selling  stockholder  notifies us that any material  arrangement has been
entered into with a broker-dealer for the sale of shares of common stock through
a block trade, special offering, exchange distribution or secondary distribution
or a purchase by a broker,  dealer or underwriter,  we will file a supplement to
this prospectus, if required,  pursuant to Rule 424(b) under the Securities Act.
In addition, to the extent required, we will amend or supplement this prospectus
to disclose other material arrangements regarding the plan of distribution.

ITEM 14.  OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION

The  following  table  sets  forth  the  costs  and  expenses  to be paid by the
registrant in connection with the sale of the common stock being registered:

     Securities and Exchange Commission registration fee.........     $   192
     Legal fees and expenses.....................................      10,000
     Accountants' fees and expenses..............................       2,000
     Miscellaneous...............................................       1,000
     Total ......................................................     $13,192
                                                                      ========


The  foregoing  items,   except  for  the  Securities  and  Exchange  Commission
registration fee, are estimated.

ITEM 15.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

Reference is made to the Amended and Restated  Certificate of Incorporation with
the  Registrant;  the  Bylaws of the  Registrant;  Section  145 of the  Delaware
General  Corporation  Law;  which,  among other  things,  and subject to certain
conditions,  authorize the Registrant to indemnify, or indemnify by their terms,
as the case may be, the directors and officers of the Registrant against certain
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   directors'  and  officers'   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
Commission on July 6, 1999; (2) the Registrant's  Bylaws filed as Exhibit 3.1 to
Registrant's  Annual  Report on Form 10-K for the year ended  December 31, 2001,

with each of its  directors  and  executive  officers  filed as Exhibit  10.1 to
Registrant's  Registration  Statement on Form S-1 filed with the  Securities and
Exchange  Commission on May 4, 1999,  each  incorporated  by reference into this

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.

                                      II-2



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.

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 a 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.
