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, chronic genetic
diseases and other diseases and conditions. In September 1998, we established a
joint venture with Genzyme for the worldwide development and commercialization
of our lead drug product, Aldurazyme(TM), for the treatment of
mucopolysaccharidosis I or MPS I, a serious genetic disease. 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 for
the treatment of MPS I 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. In addition, the European Commission has designated Aldurazyme for the
treatment of MPS I as an orphan medical product in the European Community,
giving us similar market exclusivity in Europe for 10 years.

MPS I is a life-threatening genetic disease 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. In
April 1999, we completed a twelve-month patient evaluation for the initial
clinical trial of Aldurazyme. This trial treated and evaluated ten patients with
MPS I at six medical centers in the United States. The results of the trial were
presented at the American Society for Human Genetics in October 1999. 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. We continue to collect data from the ongoing
treatment of the surviving original patients (two have died from causes
unrelated to our enzyme replacement therapy). We recently released the data from
the two-year follow-up evaluation, which continued to suggest the efficacy of
Aldurazyme.

In collaboration with Genzyme, we initiated a six-month Phase III clinical trial
of Aldurazyme in December 2000 with the intention to file a Biologics License
Application (BLA) with the FDA, pending the successful outcome of the Phase III
trial. The treatment phase of this trial was completed in August 2001 and, in
accordance with the trial protocol, we released the preliminary results of this
trial in November 2001. Patients were evaluated at defined intervals to assess
progress in meeting two primary endpoints. The preliminary data analysis showed
an increase in pulmonary capacity and demonstrated a positive trend in
endurance, as measured by a six minute walk test. Based on the results of the
trial, we plan to meet with U.S., Canadian, and European regulatory authorities
in early 2002 to discuss applications to market Aldurazyme.

In August 2000, our Galli Drive manufacturing facility and a smaller clinical
manufacturing facility 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 submitted an Investigational New Drug Application for recombinant human
N-acetylgalactosamine-4-sulfatase also known as arylsulfatase B or rhASB and
received FDA acceptance to begin a Phase I clinical trial in enzyme replacement
therapy for MPS VI, which was initiated on October 11, 2000. We released the
results of this trial in September 2001. The trial met its primary objective of
demonstrating the safety of treatment with rhASB. rhASB was well tolerated by










                                      -1-



all of the patients and there were no drug-related serious adverse events during
the study. Additionally, the trial demonstrated the efficacy of rhASB based on
various secondary endpoints. Based upon the clinical data to date, we expect to
initiate a Phase II of rhASB early in 2002.

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 our Bel Marin Keys
Boulevard clinical manufacturing facility. rhASB for the treatment of MPS VI has
received fast track and orphan drug designations from the FDA. In addition, the
European Commission has designated rhASB for the treatment of MPS VI as an
orphan medical product in the European Community.

We have successfully conducted preclinical studies of our burn enzyme,
Vibriolysin Topical, for use in burn debridement and grafting in pigs and mice.
In June 2001, we filed a Clinical Trial Exemption application with the Medicines
Control Agency in the United Kingdom for permission to begin a clinical trial
for Vibriolysin Topical. In the fourth quarter of 2001, we began a Phase I
clinical trial of Vibriolysin in the United Kingdom and we expect to begin a
Phase II clinical trial in either the United States or the United Kingdom
following completion of this Phase I trial.

On October 31, 2001 we completed the acquisition of the pharmaceutical assets of
IBEX Technologies Inc. and its subsidiaries. These assets include the
development programs related to IBEX's two lead product candidates,
Neutralase(TM) and Phenylase. Neutralase is an injectable heparinase that
reverses the anti-coagulation effects in blood of heparin. Phenylase is an
orally active enzyme with the potential to treat phenylketonuria (PKU), a
genetic disease affecting approximately 50,000 patients in North America and
Europe. Phenylase is currently in a preclinical development stage.

Neutralase is a carbohydrate-modifying enzyme that cleaves heparin in a manner
similar to the action of Aldurazyme and rhASB on specific glycosaminoglycan
(carbohydrate) structures. There are approximately 550,000 coronary artery
bypass graft procedures and 925,000 angioplasties in the United States in 1998
(as published by the American Heart Association in their 2001 Heart and Stroke
Statistical Update) that could potentially benefit from heparin reversal with
Neutralase. We believe that Neutralase may have several benefits over the only
current commercially available heparin reversal product, protamine, in that
Neutralase has demonstrated a lower occurrence of associated adverse effects in
the clinical trials conducted to date. Also, we believe, based on initial
laboratory testing, that Neutralase, unlike protamine, may be effective in
reversing the anti-coagulant effects of low molecular weight heparins and a new
pentasaccharide drug, currently under development. We expect to initiate a Phase
III clinical trial of Neutralase for use in coronary artery bypass graft surgery
in 2002, followed by a Phase IIB trial for angioplasty.

                                  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 September 30, 2001, we had an accumulated deficit of
approximately $113 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 September 30, 2001 will be sufficient to meet our operating and
capital requirements at least through the next 12 months. Additionally, since
September 30, 2001, we have completed a public offering of our common stock,
which raised net proceeds of approximately $90.4 million. We expect that these
proceeds will be sufficient to meet our operating and capital requirements for
at least an additional 12 months. 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.

We must obtain regulatory approval before marketing or selling our drug products
in the U.S. and in foreign jurisdictions. 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 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;

        o       longer treatment time required to demonstrate efficacy;



                                      -4-



        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 most 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 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.
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
127 weeks of treatment. Based on medical data collected from clinical
investigative sites, neither case 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 rhASB 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 three process qualification batches (five process qualification
batches for Europe) 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 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.

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.






                                      -5-



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 rhASB, 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 rhASB 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 rhASB 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 rhASB 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.

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.













                                      -6-



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.

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







                                   -7-



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 knowhow.

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. 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.

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.

With the exception of Aldurazyme, we have no experience manufacturing drug
products in volumes that will be necessary to support commercial sales. Our
manufacturing processes 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.

The manufacture of Neutralase involves the fermentation of a bacterial species.
We have never used a bacterial production process for the production of any
clinical or commercial production. IBEX contracted with a third party for the
manufacture of the Neutralase used in prior clinical trials.

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.

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.

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.

We may encounter problems with any of the following 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       production yields;

        o       purity;

        o       quality control and assurance systems;












                                      -9-



        o       shortages of qualified personnel; and

        o       compliance with regulatory requirements.

We have built-out approximately 67,000 square feet at our Novato facilities for
manufacturing capability for Aldurazyme and rhASB including related quality
control laboratories, materials capabilities, and support areas. We expect to
complete an expansion of the Galli Drive facility in the fourth quarter of 2001
and possibly add additional capabilities in stages over time, which create
additional operational complexity and challenges. We expect that the
manufacturing process of all of our new drug products, including rhASB 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 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, 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 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 rhASB 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 develop our own sales and
marketing force at all, 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









                                      -10-



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.

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.

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 FACERegistered Trademark 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 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 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










                                  -11-



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 we fail to effectively integrate the recently acquired Neutralase and
Phenylase programs 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, 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
IBEX's former technical staff 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 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.












                                      -12-



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, rhASB 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;

        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 all or a substantial portion of the shares of our common stock offered for
sale by this prospectus are sold in a short period of time, our stock price may
be adversely affected. Our stock price may also be adversely affected by the
perception that such sales could occur.

The shares of common stock offered for sale by this prospectus represents
approximately 2% of our outstanding common stock. Although we have an agreement
with the selling stockholders that they will not dispose of their shares in a
manner that would unduly prejudice the trading price of our common stock, we
cannot control when the selling stockholders will sell their shares. If all or a
substantial portion of the shares of common stock offered for sale by this
prospectus are sold 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 29% of the outstanding shares







                                      -13-



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 accounts of the selling stockholders.

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

                              SELLING STOCKHOLDERS

The following table sets forth the names of each selling stockholder, the
aggregate number of shares of common stock beneficially owned by each selling
stockholder as of October 31, 2001, and the aggregate number of shares of common
stock that each selling stockholder may offer and sell pursuant to this
prospectus. Because each 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 later of the date hereof or the date that certificates
representing issued shares are delivered, no estimate can be made of the number
of shares that each selling stockholder may retain upon completion of this
offering. However, assuming all of the shares offered by this prospectus are
sold by the selling stockholders then, unless otherwise noted, after completion
of this offering, none of the selling stockholders will own more than one
percent of the shares of common stock outstanding.

On October 31, 2001 we delivered certificates representing 224,750 shares of our
common stock to two of the selling stockholders and in the first week of
December 2001, we delivered certificates representing an additional 589,897
shares of our common stock to a third selling stockholder. The shares constitute
partial consideration for various pharmaceutical assets we acquired from them
and their affiliates. These assets included the Neutralase and Phenylase product
programs described in the "Summary" section of this prospectus. In addition to
the shares of common stock we also paid the selling stockholders an aggregate of
$2.0 million in cash and agreed to make contingent future payments of
approximately $5.9 million and approximately $3.6 million upon the approval of a
New Drug Application by the U.S. Food and Drug Administration for the marketing
of Neutralase and Phenylase respectively. We are registering all of the shares
of common stock offered for sale pursuant to this prospectus as required by the
asset purchase agreements related to the acquisition of these assets.

In the following table, we have calculated shares of common stock beneficially
owned based upon 52,392,341 shares of common stock outstanding on December 12,
2001, together with options, warrants or other convertible securities that are
exercisable, or other rights to acquire common stock, within 60 days of December
12, 2001 for each 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. Unless otherwise indicated
in the footnotes below, we believe that the persons and entities named in the
table have sole voting and investment power with respect to all shares
beneficially owned, subject to applicable community property laws. The
information with respect to beneficial ownership of common stock held by each
person is based upon record ownership data provided by our transfer agent,
information as supplied or confirmed by selling stockholders, based upon
statements filed with the Securities and Exchange Commission or based upon our
actual knowledge.

Except for the acquisition described above, within the past three years, none of
the selling stockholders have held any position or office with us or entered
into a material relationship with us.

                              PLAN OF DISTRIBUTION

We are registering the shares of common stock offered for sale by this
prospectus on behalf of the selling stockholders. As used in this section,
"selling stockholders" 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 stockholders or transferees. The selling
stockholders 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 stockholders
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 them.

An aggregate of 814,647 shares of common stock was originally issued to and
purchased by the selling stockholders, as partial consideration for certain
assets acquired from the selling stockholders and their affiliates by two of our
subsidiaries. All of these shares of common stock were issued and sold pursuant
to an exemption from the registration requirements of the Securities Act as
provided by Section 4(2) of the Securities Act.

Shares of common stock may be sold by the selling stockholders 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
stockholders will have the sole discretion not to accept any purchase offer or
make any sale of shares if they deem 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, none of the selling stockholders have
entered into any agreements, understandings or arrangements with any
underwriters or broker-dealers regarding the sale of their 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 stockholders may enter into agreements, understandings or arrangements
with an underwriter or broker-dealer regarding the sale of their shares in the
future.

The selling stockholders 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 a 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. There can be no assurance that all or any part of the shares
offered hereby will be sold by the selling stockholders.

The selling stockholders may enter into hedging transactions with broker-dealers
or other financial institutions with respect to the shares. In connection with
these transactions, broker-dealers or other financial institutions may engage in
short sales of the shares in the course of hedging the positions they assume
with the selling stockholders. The selling stockholders may also sell the shares
short and redeliver the shares to close out the short positions. The selling
stockholders may also enter into option or other transactions with
broker-dealers or other financial institutions that require the delivery to the
broker-dealer or other financial institutions of the shares. The selling
stockholders may also loan or pledge the shares to a financial institution or a
broker-dealer and the financial institution or the broker-dealer may sell the
shares loaned or upon a default the financial institution or the broker-dealer
may effect sales of the pledged shares.

The selling stockholders 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








                                      -17-



be deemed to be underwriting discounts or commissions under the Securities Act.
We have agreed to indemnify the selling stockholders against certain
liabilities, including liabilities arising under the Securities Act. The selling
stockholders 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 stockholders may be deemed to be "underwriters" within the
meaning of the Securities Act, the selling stockholders 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 stockholders 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.

Commencing on November 1, 2002, some of the shares of common stock covered by
this prospectus may qualify for resale pursuant to Rule 144 under the Securities
Act and such shares may be sold under Rule 144 rather than under the terms of
this prospectus. In addition, subject to applicable state and foreign laws, the
selling stockholders may sell their common stock outside the United States
pursuant to Rules 903 and 904 of Regulation S under the Securities Act.

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 a 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 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 Quarterly Report on Form 10-Q for the quarter ended March 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
Registration Statement.

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

                delivery of this Agreement and the consummation of the Canadian
                Transaction have been duly authorized by all necessary corporate
                or entity action, including without limitation, all necessary
                actions by the respective officers, directors, stockholders,
                members and managers, as applicable, on the part of each member
                of the IBEX Group.

         (c)    No Violations.  The execution and delivery of this Agreement and
                all other agreements contemplated herein by each member of the

                registration under any Law, subject to the Bulk Sales Carve-Out

                constitute a default or breach) under any Contract having an
                aggregate value of a minimum of CDN$10,000 to which any member
                of the IBEX Group is a party or by which any member of the IBEX

                creation or imposition of any Encumbrance on all or part of the
                IBEX Pharma Canadian Assets, subject to the rights of creditors
                pursuant to the Bulk Sales Carve-Out.

         (d)    Enforceability of Obligations. This Agreement constitutes a
                valid and binding obligation of each member of the IBEX Group,
                enforceable against each member of the IBEX Group in accordance
                with its terms, subject however to limitations with respect to
                enforcement imposed by law in connection with bankruptcy,
                insolvency, reorganization or other laws affecting creditors'
                rights generally.

         (e)    Acts of Bankruptcy.  None of the members of the  IBEX Group is
                insolvent, has proposed a compromise or arrangement to its
                creditors generally, has taken any proceeding with respect to a
                compromise or arrangement, has taken any proceeding to have
                itself declared bankrupt or wound-up, has taken any proceeding
                to have a receiver appointed of any part of its assets and at
                present, no encumbrancer or receiver has taken possession of any































                                      -15-



                of its property and no execution or distress is enforceable or
                levied upon any of its property and no petition for a receiving
                order in bankruptcy is filed against it.

         (f)    Resident.  Each of the Vendors is a resident of and
                maintains its principal place of business in the country and,
                as applicable, the state, province, municipality, county and
                city set out in Schedule 5.1(f).

         (g)    Title.  Each of the Vendors now has and on the Closing Date will
                have good and marketable title to the IBEX Pharma Canadian
                Assets to be conveyed by such Vendor and the Vendors,
                collectively, now have and on the Closing Date will have good
                and marketable title to all of the IBEX Pharma Canadian Assets,
                in each case, free and clear of any and all Encumbrances,
                subject to the rights of creditors pursuant to the Bulk Sales
                Carve-Out. The Vendors (and no other member of the IBEX Group or
                their respective Affiliates) are the only owners of the IBEX
                Pharma Canadian Assets. Upon the transfer of the IBEX Pharma
                Canadian Assets to BioMarin NS on the Closing Date pursuant to
                this Agreement, BioMarin NS will acquire good and marketable
                title to all of the IBEX Pharma Canadian Assets free and clear
                of any and all Encumbrances, subject to the rights of creditors
                pursuant to the Bulk Sales Carve-Out. Each of the Vendors is
                exclusively entitled to possess and dispose of the
                IBEX Pharma Canadian Assets, as the case may be. To the Best
                Knowledge of the members of the IBEX Group, no other Person owns
                or uses any assets that are required to carry on the IBEX Pharma
                Canadian Business as currently conducted. All tangible
                (corporeal) assets forming a part of the IBEX Pharma Canadian
                Assets are located as indicated at Schedule 2.1(a). The IBEX
                Pharma Canadian Assets represent all of the Therapeutic Assets
                consisting of Intellectual Property, Contracts, Permits and
                Licenses, pre-clinical and clinical trial data and books and
                records which are located in Canada.

         (h)    Certain Interests.  No member of the IBEX Group and no
                shareholder, officer, director or Affiliate of any member of
                the IBEX Group nor any relative or spouse (or relative of such
                spouse) who resides with, or is a dependent of any such Person
                owns, directly or indirectly, in whole or in part or has any
                other interest in any tangible or intangible property which
                any of the Vendors uses or has used in connection with the
                IBEX Pharma Canadian Business.

         (i)    Absence of Conflicting Agreements.  No Person has any
                written or oral agreement, option, understanding or commitment
                or any right or privilege capable of becoming an agreement,
                for the purchase from any of the Vendors of any right, title
                or interest in or to any of the IBEX Pharma Canadian Assets
                and there has been no assignment, subletting or granting of
                any license (of occupation or otherwise) of or in respect of
                any of the IBEX Pharma Canadian Assets.

                Pharma Canadian Business during the twelve-month period ended

                IBEX Group, the relations between the Vendors and the clinical
                sites of the IBEX Pharma Canadian Business are mutually
                satisfactory. None of the members of the IBEX Group have
                received written notice and, to the Actual Knowledge of the
                members of IBEX Group, none of the members of the IBEX Group
                have otherwise been made aware, of any possible termination of
                normal relations with any such Person in connection with the
                IBEX Pharma Canadian Business which termination may have a
                Material Adverse Effect on the IBEX Pharma Canadian Business.

         (l)    Litigation.  There are no Claims at Law or in equity or
                before or by any Governmental Authority, either pending or
                outstanding or, to the Actual Knowledge of the members of the
                IBEX Group, threatened against any member of the IBEX Group,
                relating to any member of the IBEX Group or which may have a
                Material Adverse Effect on the IBEX Pharma Canadian Business,
                any of the IBEX Pharma Canadian Assets or the Canadian
                Transaction.

                represents that proportion of the total inventory of the IBEX
                Group relating to the IBEX Pharma Products set forth at
                Schedule 2.1(c).

         (n)    Absence of Changes.  Since July 31, 2000 there has not been and
                up to the Closing Date there will not be;

                  (i)      any event or occurrence which either
                           individually or in the aggregate with other events or
                           occurrences that has resulted in or will result in a
                           Material Adverse Effect on the condition or operation
                           of the IBEX Pharma Canadian Business and/or the IBEX
                           Pharma Canadian Assets; or

                  (ii)     any damage, destruction or loss, labour trouble
                           or other event, development or condition of any
                           character (whether or not covered by insurance) which
                           would have a Material Adverse Effect on the IBEX
                           Pharma Canadian Business and/or the IBEX Pharma
                           Canadian Assets.

                Vendors has and up to the Closing Date none of the Vendors will
                have;

                  (i)      transferred, assigned, sold or otherwise
                           disposed of any of the IBEX Pharma Canadian Assets or
                           cancelled any debts or claims with respect thereto,
                           except in each case for fair consideration and in the
                           ordinary and usual course of the IBEX Pharma Canadian

                           generally accepted accounting principles applied on a
                           basis consistent with those of the preceding fiscal

                           course of business (all of which are consistent
                           with past practice and are not, in the aggregate
                           material to the financial condition of the members of
                           the IBEX Group) or otherwise noted or disclosed in

                           due or to become due or contingent losses for
                           unasserted claims which are capable of assertion,
                           which may be and become the responsibility or
                           obligation of BioMarin NS from and after the Closing
                           Date.

                           records of IBEX (on a consolidated basis).

                  (iv)     Contain and reflect all necessary adjustments
                           for a fair presentation of the results of operations
                           and financial position of IBEX (on a consolidated
                           basis) for the period covered thereby.

                  (v)      Contain and reflect adequate provision or

                           basis).

         (q)    Books of Account.  The books of account and financial
                records of the Vendors fairly set out and disclose in all
                material respects the current financial position of the IBEX
                Pharma Canadian Business. All material transactions with
                respect to the IBEX Pharma Canadian Assets and the IBEX Pharma
                Canadian Business have been accurately recorded in such books
                and records. All bonuses, commissions and other payments
                relating to the Therapeutic Asset Employees are reflected in
                the books of IBEX in a manner consistent with past record
                keeping practices and none of such payables are in arrears.

                the IBEX Pharma Canadian Business and to own, lease or
                operate its respective IBEX Pharma Canadian Assets at the
                places and in the manner in which the IBEX Pharma Canadian
                Business is currently conducted. The consummation of the
                Canadian Transaction will not result in the revocation,
                suspension or limitation of any of the Permits and Licenses.
                The conduct of the IBEX Pharma Canadian Business as
                currently conducted by IBEX is not impeded by the absence of
                any Permit or License and the members of the IBEX Group are
                not aware of any Permits or Licenses required to carry on
                and conduct the IBEX Pharma Canadian Business as currently
                conducted other than as itemized in Schedule 5.1(r).

         (s)    Material Contracts.  Except for the Contracts listed in Schedule
                5.1(s), no member of the IBEX Group or any of its Affiliates
                is a party to nor bound by any Contract with respect to the
                IBEX Pharma Canadian Assets, the IBEX Group Worldwide Assets
                (as defined in the US Purchase Agreement), the IBEX Pharma
                Canadian Business or the IBEX Group Worldwide Business (as
                defined in the US Purchase Agreement). Schedule 5.1(s)
                additionally sets forth a true and complete list of all
                Canadian Assigned Rights and Worldwide Assigned Rights (as
                defined on the US Purchase Agreement) requiring the consent
                of any party thereto as a result of the Canadian Transaction
                or the Worldwide Transaction (as defined in the US Purchase
                Agreement) and all additional consents, authorizations and
                approvals of any Person to or as a result of the
                consummation of the Canadian Transaction. All such consents,
                authorizations and approvals described in Schedule 5.1(s)
                will be lawfully and validly obtained prior to or after the
                Closing Date (as indicated in such Schedule). For greater
                certainty and without limitation, IBEX Pharma has no
                unfilled orders in connection with the IBEX Pharma Canadian
                Business and no forward commitments for suppliers or

                minimum aggregate value of CDN$10,000 are all in full force
                and effect, unamended and no material default or breach
                exists (nor would the passage of time or the giving of
                notice of both or otherwise, constitute a default or breach)
                in respect thereof on the part of any of the parties
                thereto. No member of the IBEX Group has entered into any
                Contract limiting or restricting the IBEX Pharma Canadian
                Business.

                Employees). To the Best Knowledge of each member of the IBEX
                Group, there are no current attempts to organize or to
                establish any labour union or employee association with
                respect to the Therapeutic Asset Employees.

         (w)    Labour Matters.  There are no controversies pending or to the
                Best Knowledge of each Vendor,  threatened between any

                appropriate to the IBEX Pharma Canadian Business and the
                IBEX Pharma Canadian Assets, in such amounts and against
                such risks as are customarily carried and insured against by
                owners of comparable businesses, properties and assets. All
                such policies of insurance are in full force and effect and

                payment of premiums or otherwise under the terms of any such
                policy. All of such policies are listed in Schedule 5.1(x).
                All premiums in connection with such policies are fully
                paid. None of the Vendors has failed to give any notice or
                present any Claim under any such insurance policies in due
                and timely fashion. The proceeds of such policies are and
                until Closing shall continue to be fully payable to the
                Vendors. None of the Vendors is in default with respect to
                any of the provisions contained in such insurance policies
                and none of the Vendors have failed to give any notice or

                in accordance with all applicable Laws and Governmental Orders,
                except where the failure to comply with such Laws and
                Governmental Orders would not have a material adverse effect on
                the IBEX Pharma Canadian Assets or the conditions, operations or

                have not received any notice in writing and, to the Actual

5.2  Investment Representations.  Each Vendor hereby solidarily represents
     and warrants to BioMarin that:

         (a)    Such Vendor is acquiring the BioMarin Canadian
                Transaction Shares for investment purposes only, for its own
                account and not as nominee or agent for any other Person and
                not with the view to or for resale in connection with any
                distribution thereof within the meaning of the Securities Act.

         (b)    Such Vendor knows of no public solicitation or
                advertisement of an offer in connection with the BioMarin
                Canadian Transaction Shares.

         (c)    Such Vendor has carefully reviewed this Agreement.
                During the course of the Canadian Transaction and prior to the
                purchase of the BioMarin Canadian Transaction Shares, such
                Vendor has had the opportunity to ask questions of and receive
                answers from BioMarin concerning the terms and conditions of
                the Canadian Transaction and to obtain additional information
                concerning the Canadian Transaction, BioMarin and the BioMarin
                Canadian Transaction Shares. Such Vendor has received all
                information that it has requested regarding BioMarin and
                believes that such information is sufficient to make an
                informed decision with respect to the purchase of the BioMarin
                Canadian Transaction Shares.

         (d)    Such Vendor is able to bear the economic risk of its
                investment in the BioMarin Canadian Transaction Shares and has
                such knowledge and experience in financial and business
                matters that it is capable of evaluating the merits and risks
                of and protecting its interests with respect to its investment
                in the BioMarin Canadian Transaction Shares. Such Vendor is
                aware of the risk involved in its investment in the BioMarin
                Canadian Transaction Shares and has determined that such
                investment is suitable for such Vendor in light of its
                financial circumstances and available investment
                opportunities.

         (e)    Such Vendor is an "accredited  investor" as that term is defined
                in Rule 501 of Regulation D promulgated under the Securities
                Act.

         (f)    The purchase by such Vendor of the BioMarin Canadian
                Transaction Shares hereunder does not violate or conflict with
                any Law applicable to such Vendor.

         (g)    Each Vendor hereby further agrees with BioMarin that
                the instruments or certificates evidencing the BioMarin
                Canadian Transaction Shares and each instrument or certificate
                issued in transfer thereof will bear the following legend:

                           "The securities evidenced by this certificate have
                           not been registered under the Securities Act of 1933
                           and have been taken for investment purposes only and
                           not with a view to the distribution thereof, and,
                           except as stated in an agreement between the holder
                           of this certificate, or its predecessor in interest,
                           and the issuer corporation, such securities may not
                           be sold or transferred unless there is an effective

                Vendor, unless there is in effect a registration statement
                under the Securities Act covering the proposed transfer,
                such Vendor shall give written notice to BioMarin of such
                Vendor's intention to effect such transfer, sale, assignment
                or pledge. Each such notice shall describe the manner and
                circumstances of the proposed transfer, sale, assignment or

                proposed transfer of the BioMarin Canadian Transaction
                Shares may be effected without registration under the
                Securities Act, whereupon the holder of such BioMarin
                Canadian Transaction Shares shall be entitled to transfer
                such BioMarin Canadian Transaction Shares in accordance with
                the terms of the notice delivered by such Vendor to
                BioMarin.


































                                      -27-

                exemption from the registration requirements of the Securities

                Transaction Shares and the Underlying Securities are duly
                authorized and, in the case of the BioMarin Canadian
                Transaction Shares, when issued and paid for in accordance

                Securities Act, other securities laws or this Agreement.

         (h)    Regulatory Approvals. Based in part on the
                representations and warranties made by the members of the IBEX
                Group in section 5.2, no authorization from any Governmental
                Authority is required on the part of BioMarin in connection
                with the issuance of the BioMarin Canadian Transaction Shares,
                the BioMarin Options and the Underlying Securities, save and

                to in section 12.1(k) hereof.

         (i)    Registrant Status. No securities commission or similar
                regulatory authority has issued any order preventing or
                suspending trading in any securities of BioMarin or
                prohibiting the issue and sale of the BioMarin Canadian
                Transaction Shares and to the Best Knowledge of the members of
                the BioMarin Group, no such proceedings for such purposes are
                pending or threatened.

         (j)    Litigation There are no Claims at Law or in equity or
                before or by any Governmental Authority either threatened,
                pending, outstanding or contemplated against any member of the
                BioMarin Group or relating to or which may have a Material
                Adverse Effect on any member of the BioMarin Group nor to the
                Best Knowledge of any member of the BioMarin Group, is there
                any basis upon which any such Claims might at any time in the
                future be founded.

                balance sheets of BioMarin and the consolidated statements of
                operations and consolidated statements of changes in

                           applied on a basis consistent with those of the
                           preceding fiscal period.

                has been carrying on business in all material respects in
                accordance with all applicable Laws and Governmental Orders
                and no member of the BioMarin Group is in violation of any
                such Law or Governmental Order, except where such violation
                would not have a Material Adverse Effect on the members of the
                BioMarin Group.

         (m)    No Brokers. There is no broker, finder or other
                intermediary acting on behalf of any member of the BioMarin
                Group, other than Leerink, Swann & Associates, who has or will
                have a claim against the members of the IBEX Group for a
                brokerage commission, finders' fee or other like payment for
                the Canadian Transaction and as and by way of a post-closing
                covenant the members of the BioMarin Group will solidarily
                indemnify and save harmless the members of the IBEX Group of
                and from such Claim.

         (n)    Reporting Status; No Termination of Registration.  Except as
                set forth on Schedule 6.1(n) hereto, BioMarin has filed in a
                timely manner all documents that BioMarin was required to
                file under the Exchange Act during the 24 months preceding
                the date of this Agreement and such documents complied in
                all material respects with the Commission's requirements as
                of their respective filing dates, and the information
                contained therein as of the date thereof did not contain any
                untrue statement of a material fact or omit to state a
                material fact required to be stated therein or necessary to
                make the statements therein in light of the circumstances in
                which they were made not misleading. BioMarin has not
                received notice of the issuance by the Commission of any
                stop order suspending the qualification of any shares of
                BioMarin common stock for offering or sale in any
                jurisdiction or the initiation of any proceeding for such

7.       Registration of BioMarin Canadian Transaction Shares

7.1  Required Registration.

         (a)    Within five days following the Closing Date, BioMarin
                shall prepare and file a registration statement on Form S-3
                under the Securities Act, covering the BioMarin Canadian
                Transaction Shares and shall use its best efforts to cause
                such registration statement to become effective as
                expeditiously as possible and to remain effective until the
                earliest to occur of: (i) the date the BioMarin Canadian
                Transaction Shares covered thereby have been sold; (ii) the
                date by which all BioMarin Canadian Transaction Shares covered
                thereby may be sold under Rule 144 without restriction as to
                volume; or (iii) the date which is the twenty-fourth month
                anniversary of the Closing Date.
































                                      -31-



         (b)    Following the effectiveness of a registration statement filed
                pursuant to this section, BioMarin may at any time suspend
                the effectiveness of such registration for up to 60 days, as
                appropriate (a "Suspension Period"), by giving notice to the
                Vendors, if BioMarin shall have determined that BioMarin may
                be required to disclose any material corporate development
                which disclosure may have a Material Adverse Effect on
                BioMarin. Notwithstanding the foregoing, no more than two
                Suspension Periods may occur during any 12 month period.
                BioMarin shall use its best efforts to limit the duration
                and number of any Suspension Periods. The Vendors agree that
                upon receipt of any notice from BioMarin of a Suspension
                Period, the Vendors shall forthwith discontinue disposition
                of BioMarin Canadian Transaction Shares covered by such
                registration statement or prospectus until the Vendors: (i)
                are advised in writing by BioMarin that the use of the
                applicable prospectus may be resumed; (ii) have received
                copies of a supplemental or amended prospectus, if
                applicable; and (iii) have received copies of any additional
                or supplemental filings which are incorporated or deemed to
                be incorporated by reference into such prospectus.

7.2  Registration Procedures.  At such time as BioMarin effects the registration
of the BioMarin Canadian Transaction Shares under the Securities Act pursuant to
section 7.1(a) BioMarin will, at its expense and as expeditiously as possible;

         (a)    In accordance with the Securities Act and the rules and
                regulations of the Commission, prepare and file in accordance
                with section 7.1(a) a registration statement with respect to
                the BioMarin Canadian Transaction Shares and will use its best
                efforts to cause such registration statement to become and
                remain effective for the period described herein and BioMarin
                will prepare and file with the Commission such amendments to
                such registration statement and supplements to the prospectus
                contained therein as may be necessary to keep such
                registration statement effective for such period and such
                registration statement and prospectus accurate and complete
                for such period.

         (b)    Furnish to the Vendors participating in such
                registration such reasonable number of copies of the
                registration statement, preliminary prospectus, final
                prospectus and such other documents as such Vendors may
                reasonably request in order to facilitate the public offering
                of the BioMarin Canadian Transaction Shares.

         (c)    Use its best efforts to register or qualify the
                BioMarin Canadian Transaction Shares covered by such
                registration statement under such state securities or blue sky
                laws of such jurisdictions as such participating Vendors may
                reasonably request within 20 days following the original
                filing of such registration statement, except that BioMarin
                shall not for any purpose be required to execute a general
                consent to service of process or to qualify to do business as
                a foreign corporation in any jurisdiction where it is not so
                qualified.





























                                      -32-



         (d)    Notify the Vendors participating in such registration,
                promptly after BioMarin shall receive notice thereof, of the
                date and time when such registration statement and each
                post-effective amendment thereto has become effective or a
                supplement to any prospectus forming a part of such
                registration statement has been filed.

         (e)    Notify such Vendors promptly of any request by the
                Commission for the amending or supplementing of such
                registration statement or prospectus or for additional
                information.

         (f)    Prepare and file with the Commission, promptly upon the
                request of any such Vendors, any amendments or supplements to
                such registration statement or prospectus which, in the
                opinion of counsel for such Vendors, is required under the
                Securities Act or the rules and regulations thereunder in
                connection with the distribution of the BioMarin Canadian
                Transaction Shares by such Vendors.

         (g)    Prepare and promptly file with the Commission and
                promptly notify such Vendors of the filing of, such amendments
                or supplements to such registration statement or prospectus as
                may be necessary to correct any statements or omissions if at
                the time when a prospectus relating to such securities is
                required to be delivered under the Securities Act any event
                has occurred as the result of which any such prospectus or any
                other prospectus as then in effect would include an untrue
                statement of a material fact or omit to state any material
                fact required to be stated therein or necessary to make the
                statements therein not misleading.

         (h)    Advise such Vendors, promptly after BioMarin shall
                receive notice or obtain knowledge thereof, of the issuance of
                any stop order by the Commission suspending the effectiveness
                of such registration statement or the initiation or
                threatening of any proceeding for that purpose and promptly
                use its best efforts to prevent the issuance of any stop order
                or to obtain its withdrawal if such stop order should be
                issued.

7.3  Covenant Regarding Disposition of BioMarin Shares. Following the
effectiveness of a registration statement filed pursuant to section 7.1 and
without limitation of the provisions of section 7.1(b), the Vendors solidarily
covenant and agree that any disposition of the BioMarin Canadian Transaction
Shares shall be made in a manner that does not unduly prejudice the trading
price of BioMarin's common stock on the Nasdaq National Market or the SWX Swiss
Market.

7.4  Indemnification.

         (a)    BioMarin will indemnify and hold harmless each Vendor which is
                an owner of shares of BioMarin Canadian Transaction Shares
                included in a registration statement pursuant to the provisions
                of Article 7 hereof, and any officer, director, employee, agent,
                partner, member or affiliate of such Vendor (for purposes of





























                                      -33-



                this section 7.4(a), the "Indemnified Parties"), from and
                against, and will reimburse such Vendor and each such
                Indemnified Party with respect to, any and all claims, actions,
                demands, losses, damages, liabilities, costs and expenses to
                which such Vendor or any such Indemnified Party may become
                subject under the Securities Act or otherwise, insofar as such
                claims, actions, demands, losses, damages, liabilities, costs or
                expenses arise out of or are based upon any untrue statement or
                alleged untrue statement of any material fact contained in such
                registration statement, any prospectus contained therein or any
                amendment or supplement thereto, or arise out of or are based
                upon the omission or alleged omission to state therein a
                material fact required to be stated therein or necessary to make
                the statements therein not misleading; provided, however, that
                BioMarin will not be liable in any such case to the extent that
                any such claim, action, demand, loss, damage, liability, cost or
                expense is caused by an untrue statement or alleged untrue
                statement or omission or alleged omission so made in conformity
                with information furnished by such Vendor or such Indemnified
                Party in writing specifically for use in the preparation
                thereof.

         (b)    Each Vendor which is an owner of shares of BioMarin Canadian
                Transaction Shares included in a registration statement
                pursuant to the provisions of Article 7 hereof will
                indemnify and hold harmless BioMarin, and any Person who
                controls BioMarin within the meaning of the Securities Act,
                from and against, and will reimburse BioMarin and such
                controlling Persons with respect to, any and all losses,
                damages, liabilities, costs or expenses to which BioMarin or
                such controlling Person may become subject under the
                Securities Act or otherwise, insofar as such losses,
                damages, liabilities, costs or expenses are caused by any
                untrue or alleged untrue statement of any material fact
                contained in such registration statement, any prospectus
                contained therein or any amendment or supplement thereto, or
                are caused by the omission or the alleged omission to state
                therein a material fact required to be stated therein or
                necessary to make the statements therein, in light of the
                circumstances in which they were made, not misleading, in
                each case to the extent, but only to the extent, that such
                untrue statement or alleged untrue statement or omission or
                alleged omission was so made solely in reliance upon and in
                conformity with written information furnished by such Vendor
                specifically for use in the preparation thereof; provided,
                however, that the liability of any Vendor pursuant to this
                subsection (b) shall be limited to an amount not to exceed
                the net proceeds received by such Vendor pursuant to the
                registration statement which gives rise to such obligation
                to indemnify.

         (c)    Promptly after receipt by a party indemnified pursuant to the
                provisions of paragraph (a) or (b) of this section 7.4 of
                notice of the commencement of any action involving the
                subject matter of the foregoing indemnity provisions, such
                indemnified party will, if a claim thereof is to be made
                against the indemnifying party pursuant to the provisions of
                paragraph (a) or (b), notify the indemnifying party of the



























                                      -34-



                commencement thereof; but the omission so to notify the
                indemnifying party will not relieve it from any liability
                which it may have to an indemnified party otherwise than
                under this section 7.4 and shall not relieve the
                indemnifying party from liability under this section 7.4
                unless such indemnifying party is prejudiced by such
                omission. In case such action is brought against any
                indemnified party and it notifies the indemnifying party of
                the commencement thereof, the indemnifying party shall have
                the right to participate in, and, to the extent that it may
                wish, jointly with any other indemnifying party similarly
                notified, to assume the defense thereof, with counsel
                reasonably satisfactory to such indemnified party, and after
                notice from the indemnifying party to such indemnified party
                of its election so to assume the defense thereof, the
                indemnifying party will not be liable to such indemnified
                party pursuant to the provisions of such paragraph (a) or
                (b) for any legal or other expense subsequently incurred by
                such indemnified party in connection with the defense
                thereof other than reasonable costs of investigation. No
                indemnifying party shall be liable to an indemnified party
                for any settlement of any action or claim without the
                consent of the indemnifying party. No indemnifying party
                will consent to entry of any judgment or enter into any
                settlement which does not include as an unconditional term
                thereof the giving by the claimant or plaintiff to such
                indemnified party of a release from all liability in respect
                to such claim or litigation. (d) If the indemnification
                provided for in subsection (a) or (b) of this section 7.4 is
                held by a court of competent jurisdiction to be unavailable
                to a party to be indemnified with respect to any claims,
                actions, demands, losses, damages, liabilities, costs or
                expenses referred to therein, then each indemnifying party
                under any such subsection, in lieu of indemnifying such
                indemnified party thereunder, hereby agrees to contribute to
                the amount paid or payable by such indemnified party as a
                result of such claims, actions, demands, losses, damages,
                liabilities, costs or expenses in such proportion as is
                appropriate to reflect the relative fault of the
                indemnifying party on the one hand and of the indemnified
                party on the other in connection with the statements or
                omissions which resulted in such claims, actions, demands,
                losses, damages, liabilities, costs or expenses, as well as
                any other relevant equitable considerations. The relative
                fault of the indemnifying party and of the indemnified party
                shall be determined by reference to, among other things,
                whether the untrue or alleged untrue statement of a material
                fact or the omission or alleged omission to state a material
                fact relates to information supplied by the indemnifying
                party or by the indemnified party and the parties' relative
                intent, knowledge, access to information and opportunity to
                correct or prevent such statement or omission. The amount
                any Vendor shall be obligated to contribute pursuant to this
                subsection (d) shall be limited to an amount not to exceed
                the net proceeds received by such Vendor pursuant to the
                registration statement which gives rise to such obligation
                to contribute. No person guilty of fraudulent
                misrepresentation (within the meaning of section 11(f) of
                the Securities Act) shall be entitled to contribution
                hereunder from any person who was not guilty of such
                fraudulent misrepresentation.

8.       SURVIVAL OF REPRESENTATIONS AND WARRANTIES

8.1  Survival.  No investigations made by or on behalf of any Party at any
time shall have the effect of waiving, diminishing the scope of or otherwise
affecting any representation or warranty made by any Party. No waiver by any
Party of any condition, in whole or in part, shall operate as a waiver of any
other condition. The representations and warranties contained in Article 5 and 6
respectively or in any certificate or other document delivered in connection
with the Closing shall survive the making of this Agreement and the Closing as
to the representations and warranties contained in section 5.1(g), 5.1(l),
5.1(y) and 5.1(bb), for a period of six years; and as to all other
representations and warranties, for a period of three years following the
Closing unless a bona fide notice of a Claim shall have been given in writing
prior to the expiry of that period, in which case the representations and
warranties to which such notice applies shall survive in respect of that Claim
until the final determination or the applicable settlement, in each case, of
that Claim.


9.       COVENANTS

9.1  Interim Covenants.  From the date hereof and up to and including the

                and shall take any and all such further actions reasonably
                requested by the members of the BioMarin Group to the end that

                material respect on the Closing Date.

         (b)    Insurance.  The Vendors shall keep in full force their
                current insurance policies relating to the IBEX Pharma

                permitting any termination, cancellation or lapse thereof and
                the Vendors shall enter into replacement policies providing
                coverage equal to or greater than the coverage under those
                cancelled, terminated or lapsed policies for substantially
                similar premiums.

                purchases of supplies of inventories in the usual and ordinary
                course of the IBEX Pharma Canadian Business consistent with

                the aggregate, are not material to the IBEX Pharma Canadian
                Business. For purposes of the proceeding sentence, any
                Contract in excess of CDN$50,000 shall be considered material
                to the IBEX Pharma Canadian Business. No member of the IBEX
                Group or their Affiliates shall otherwise make any material
                change in the conduct of the IBEX Pharma Canadian Business.

         (g)    Disposition of IBEX Pharma Canadian Assets.  The Vendors
                shall not sell, lease or transfer or agree to sell, lease or

                Canadian Assets, out of the ordinary course of the IBEX Pharma
                Canadian Business or approve or undertake any other
                transaction out of the ordinary course of the IBEX Pharma

                information concerning the IBEX Pharma Canadian Assets and/or
                the IBEX Pharma Canadian Business to any third Person who is
                interested in any such transaction.

                Vendors shall not increase in any manner the compensation,
                bonuses or benefits of any of the Therapeutic Asset Employees
                or pay or agree to pay any bonus or pension or retirement
                allowance or other employee benefit not required by any
                existing Employee Plan or Contract or commit to any new or
                renewed Employee Plans or to any employment Contract (or

                benefit of any Therapeutic Asset Employee and the Vendors
                shall not amend any of the foregoing now in existence.

         (i)    Representations and Warranties.  The members of the IBEX
                Group shall not do anything that would cause any of the
                representations and warranties under Article 5 to be false,
                incomplete or misleading in such a fashion so as to have a
                Material Adverse Effect on the members of the IBEX Group.































                                      -37-



         (j)    Advice.  The members of the IBEX Group shall promptly
                advise the members of the BioMarin Group in writing of any
                change that would have a Material Adverse Effect on the
                condition, financial or otherwise of the IBEX Pharma Canadian
                Assets and/or the IBEX Pharma Canadian Business.

         (k)    Accounting.  With respect to the IBEX Pharma Canadian
                Business and the IBEX Pharma Canadian Assets, no member of the
                IBEX Group shall make any change in the accounting principles,

                compromise, release or discharge any Claim in connection with
                the operation of the IBEX Pharma Canadian Assets upon or

10.      INDEMNITY

10.1  Indemnity by the Members of the BioMarin Group.  The members of the
BioMarin Group shall solidarily indemnify and save harmless the members of the
IBEX Group from all Losses actually incurred by the members of the IBEX Group as
a result of: (i) any breach by the members of the BioMarin Group or any
inaccuracy of any covenant, representation or warranty of the members of the
BioMarin Group contained in this Agreement; and (ii) any actual action, suit,
investigation, inquiry or proceeding (each, an "Action") arising out of or
resulting from the conduct of the IBEX Pharma Canadian Business or any of the
IBEX Pharma Canadian Assets by members of the BioMarin Group after the Closing
Date.

10.2  Indemnity by the Members of the IBEX Group.  The members of the IBEX
Group shall solidarily indemnify and save harmless the members of the BioMarin
Group from all Losses actually incurred by the members of the BioMarin Group as
a result of: (i) any breach by any member of the IBEX Group or any inaccuracy of
any covenant, representation or warranty of any member of the IBEX Group
contained in this Agreement; (ii) any Action arising from rights of creditors
pursuant to the Bulk Sales Carve-Out or any Action arising from rights of
creditors pursuant to any non-compliance by BioMarin NS with section 1767 ss of
the Civil Code of Quebec in connection with the Canadian Transaction; or (iii)
any Excluded Liability; or (iv) any Action arising out of or resulting from the
conduct of the IBEX Pharma Canadian Business or any of the IBEX Pharma Canadian
Assets by the members of the IBEX Group prior to the Closing Date; and (v) any
Action arising from the failure of the members of the IBEX Group to comply with
any covenants contained in this Agreement.

10.3  Indemnification Procedure.  An indemnified party pursuant to the
provisions hereof (the "Indemnified Party") shall give the other Party (the
"Indemnitor") notice of any matter which an Indemnified Party has determined has
given or could give rise to a right of indemnification under this Agreement,
within 60 days of such determination, stating the amount of the Loss if known
and the method of computation thereof and containing a reference to the
provisions of this Agreement in respect of which such right of indemnification
is claimed. If an Indemnified Party shall receive notice of any third party
claim (a "Third Party Claim"), the Indemnified Party shall give the Indemnitor
notice of the Third Party Claim within 30 days of the receipt by the Indemnified
Party of such notice. The failure to provide such notice shall not release the
Indemnitor from its obligations under this Article except to the extent that the
Indemnitor is materially prejudiced by such failure and shall not relieve the
Indemnitor from any other obligation or liability that it may have to the
Indemnified Party other than under this Article. If the Indemnitor acknowledges
in writing its obligation to indemnify the Indemnified Party hereunder against
any Losses that may result from such Third Party Claim within 20 days of receipt

































                                      -39-



of notice of such Claim, the Indemnitor shall be entitled to assume and control
the defense of such Third Party Claim at its expense and through counsel of its
choice if it gives notice of its intention to do so to the Indemnified Party
within five days of the receipt of such notice from the Indemnified Party. If
there exists or is reasonably likely to exist a conflict of interest that would
make it inappropriate in the judgment of the Indemnified Party, in its sole and
absolute discretion, for the same counsel to represent both the Indemnified
Party and the Indemnitor or if the Indemnitor does not so assume and defend such
Third Party Claim, the Indemnified Party shall be entitled to retain its own
counsel, in each jurisdiction for which the Indemnified Party determines counsel
is required, at the expense of the Indemnitor. If the Indemnitor exercises the
right to undertake any such defense against any Third Party Claim, the
Indemnified Party shall cooperate with the Indemnitor in such defense and shall
make available to the Indemnitor, at the Indemnitor's expense, all witnesses,
pertinent records, materials and information in the Indemnified Party's
possession or under the Indemnified Party's control relating thereto as is
reasonably required by the Indemnitor. If the Indemnified Party is directly or
indirectly conducting the defense against any such Third Party Claim, the
Indemnitor shall cooperate with the Indemnified Party in such defense and shall
make available to the Indemnified Party, at the Indemnitor's expense, all such
witnesses, records, materials and information in the Indemnitor's possession or
under the Indemnitors' control relating thereto as is reasonably required by the
Indemnified Party. No such Third Party Claim may be settled by the Indemnitor
without the prior written consent of the Indemnified Party, acting reasonably.
For the purposes of this Article 10, the members of the BioMarin Group shall be
treated as one Party and the members of the IBEX Group shall be treated as one
Party.

10.4  Supplemental Rights.  The rights and benefits provided in this Article
10 are supplemental to and are without prejudice to any other rights, actions or
causes of action which may arise pursuant to any other section of this Agreement
or pursuant to applicable law.

10.5   Reduction of Canadian Purchase Price.  All amounts received by the
members of the BioMarin  Group  pursuant to the provisions of this Article shall
be received in  reduction  of the  Canadian  Purchase  Price.

10.6  Minimum and Maximum Indemnification Claim. Notwithstanding the provisions
of section 10.1(i) and (ii) or 10.2(i) and (iv), as the case may be, the
obligation of the members of the BioMarin Group or the members of the IBEX
Group, as the case may be, to indemnify the other Parties in respect of any of
the matters described therein, as the case may be, shall become applicable only
when the Losses actually incurred by the Person entitled to indemnification
exceed in the aggregate CDN$100,000 under this Agreement and/or the U.S.
Purchase Agreement (the "Minimum Threshold"). Once the Minimum Threshold has
been exceeded, the obligations of indemnification with respect to such matters
shall apply to (i) 50% of any and all Losses from dollar one above the first
CDN$50,000 to CDN$100,000 of such Losses and (ii) any and all Losses from dollar
one above CDN$100,000 of such Losses. The right of indemnification with respect
to such matters shall only apply to Losses (exclusive of Losses relating to
breaches of representations and warranties set forth in sections 5.1(l) and
5.1(bb), and any other matters relating to the Excluded Liabilities, and rights

































                                      -40-



of creditors pursuant to the Bulk Sales Carve-Out and rights of creditors
pursuant to the matters described in section 10.2(ii), for which there shall be
no limitation) under this Agreement and the U.S. Purchase Agreement which
aggregate up to and including the sum of (a) the Canadian Purchase Price, (b)
the Worldwide Purchase Price (as defined in the U.S. Purchase Agreement) and (c)
the Contingency Payments (as defined in the U.S. Purchase Agreement).

10.7  Rights of Set-Off. Subject to section 10.6, in the event the members
of the BioMarin Group have incurred Losses and the members of the IBEX Group
must indemnify the members of the BioMarin Group pursuant to the provisions
hereof, BioMarin shall have the right to set off such Losses as against the
Contingency Payments (as defined in the U.S. Purchase Agreement).

a third Person if such consent has not been obtained and such assignment or
attempted assignment would constitute a breach thereof; or (ii) in respect of

obtained or such Canadian Assigned Right otherwise becomes assignable, the

consideration therefor, assume such rights and obligations and the Vendors shall
be relieved of any and all liability therefor.

Canadian Transaction to be consummated; (iii) the Parties shall cooperate with
each other to provide such information, to execute and deliver such other
documents, instruments of transfer or assignment, files, books and records and
to do all such further acts and things as may be reasonably required to carry
out the Canadian Transaction; (iv) the Parties shall use all reasonable efforts
to comply promptly with all legal requirements that may be imposed upon them
with respect to the consummation of the Canadian Transaction and to obtain any
consent or any exemption by and to make any registration, declaration or filing
with any Governmental Authority or other third Person required to be obtained or
made by such Person in connection with the taking of any action contemplated
hereby, including without limitation, the post-Closing Canadian Assigned Rights
Consents. The Parties covenant and agree to proceed diligently and in a
coordinated fashion to apply for and obtain any and all necessary approvals
and/or Canadian Assigned Rights Consents. For greater certainty and without
limitation, at the request of any member of the BioMarin Group, prior to and


































                                      -47-



after Closing, the Representatives of the BioMarin Group shall have full right
to participate in discussions with all third Persons with a view to procuring
all pre-Closing and post-Closing Canadian Assigned Rights Consents; provided,
however, that in the event that from and after Closing, any member of the IBEX
Group has not proceeded diligently and in a coordinated fashion to apply for and
obtain any and all such necessary approvals and/or Canadian Assigned Rights
Consents, the members of the BioMarin Group, without any further or other act or
formality shall be irrevocably appointed to act as attorney and mandatory for
and on behalf of any or all of the members of the IBEX Group in their place and
stead, with full power of substitution. Notwithstanding the foregoing, the

16.1  No Solicitation.  From the date hereof and up to and including the
Closing Date or other termination of this Agreement, other than in connection
with the Canadian Transaction, the members of the IBEX Group solidarily covenant
and agree that neither they nor any their Affiliates shall nor shall any of the
members of the IBEX Group or any of their Affiliates permit their respective
Representatives to initiate, solicit or encourage, directly or indirectly, any
inquiries or the making or implementation of any proposal or offer (including
without limitation, any proposal or offer to shareholders) with respect to an
Acquisition Proposal or engage in negotiations concerning or provide any
confidential information or data to, have any discussions with or endorse or
recommend a proposal of or enter into any contract or understanding with any
Person relating to an Acquisition Proposal or otherwise facilitate any effort or
attempt to make or implement an Acquisition Proposal. The members of the IBEX
Group shall notify the members of the BioMarin Group immediately if any such
inquiries or proposals are received by, any such information is requested from
or any such negotiations or discussions are sought to be initiated or continued
with the members of the IBEX Group or any of their Affiliates or
Representatives; provided however that nothing contained in this section shall
prohibit the board of directors of IBEX from furnishing non-public information
to or entering into discussions or negotiations with any Person that makes an
unsolicited bona fide Acquisition Proposal, if and only to the extent that: (i)
the board of directors of IBEX, based upon the advice of outside counsel,
determines in good faith that such action is required for the board of directors
of IBEX to comply with its fiduciary duties to shareholders imposed by
applicable Law; (ii) prior to furnishing such information to or entering into
discussions or negotiations with such Person, the members of the IBEX Group keep
the members of the BioMarin Group informed of the status and all material
information with respect to any such discussions or negotiations. Nothing in
this section shall permit the members of the IBEX Group to terminate this
Agreement or permit the members of the IBEX Group to enter into any agreement
with respect to an Acquisition Proposal for so long as this Agreement remains in

































                                      -50-



effect (it being agreed that for so long as this Agreement remains in effect,
none of the members of the IBEX Group nor their Affiliates shall enter into any
agreement with any Person that provides for or in any way facilitates an
Acquisition Proposal or affect any other obligation of the members of the IBEX
Group under this Agreement).


17.      CANADIAN ASSETS AT RISK UNTIL CLOSING

17.1  Risk.  Notwithstanding anything herein contained, title and risk of
loss of the IBEX Pharma Canadian Assets shall remain with the Vendors until the
Canadian Transaction has been completed as herein contemplated. The Vendors
shall maintain the insurance represented herein to be held by them on the IBEX
Pharma Canadian Assets until the Closing Date and the Vendors shall hold any
proceeds thereof in trust for the Parties as their interests may appear.

17.2  Reduction of Canadian Purchase Price.  In the event of damage or
destruction to the IBEX Pharma Canadian Fixed Assets prior to the Closing Date,
to the extent not repaired or replaced by the members of the IBEX Group on or
before the Closing Date to the satisfaction of the members of the BioMarin
Group, the replacement value of the IBEX Pharma Canadian Fixed Assets so damaged
or destroyed as determined by the members of the BioMarin Group and the members
of the IBEX Group in consultation with the insurer of the members of the IBEX
Group shall be deducted from the Canadian Purchase Price. Without limitation of
any of the rights of the members of the IBEX Group hereunder, such amounts may
be reduced from the Canadian Purchase Price by the cancellation of a sufficient
number of BioMarin Canadian Transaction Shares that would otherwise be issuable
hereunder.


18.      DELIVERY OF BOOKS AND RECORDS OF THE VENDORS

18.1  Books and Records.  On the Closing Date all books, documents and data
solely relating to the IBEX Pharma Canadian Business shall be transferred by the

                           which are capable of assertion, which may be and
                           become the responsibility or obligation of BioMarin
                           US from and after the Closing Date.

                  (iii)    Are substantially in accordance with the books and
                           records of IBEX (on a consolidated basis).

               material respects, the current financial position of the IBEX
               Group Worldwide Business. All material transactions with
               respect to the Worldwide Assets and the IBEX Group Worldwide
               Business have been accurately recorded in such books and
               records. All bonuses, commissions and other payments relating
               to the Therapeutic Asset Employees are reflected in the books

               the revocation, suspension or limitation of any of the Permits
               and Licenses. The conduct of the IBEX Group Worldwide Business as
               currently conducted by the members of the IBEX Group is not
               impeded by the absence of any Permit or License and the members
               of the IBEX Group are not aware of any Permits or Licenses
               required to carry on and conduct the IBEX Group Worldwide
               Business as currently conducted other than as itemized in
               Schedule 5.1(r).

               or the IBEX Pharma Canadian Business (as defined in the Canadian

               Canadian Assigned Rights (as defined in the Canadian Purchase
               Agreement) requiring the consent of any party thereto as a result
               of the Worldwide Transaction or the Canadian Transaction and all
               additional consents, authorizations and approvals of any Person
               to or as a result of the consummation of the Worldwide
               Transaction. All such consents, authorizations and approvals
































                                      -22-

               obtained prior to or after the Closing Date (as indicated in such
               Schedule). For greater certainty and without limitation, the

               with the IBEX Group Worldwide Business and no forward commitments
               for suppliers or materials. The Contracts listed in Schedule
               5.1(s) having a minimum aggregate value of CDN$10,000 are all in
               full force and effect, unamended and no material default or
               breach exists (nor would the passage of time or the giving of
               notice of both or otherwise, constitute a default or breach) in
               respect thereof on the part of any of the parties thereto. No
               member of the IBEX Group has entered into any Contract limiting
               or restricting the IBEX Group Worldwide Business.

               there are no Employee Plans with respect to the Therapeutic
               Asset Employees. All obligations of each of the Vendors,
               whether arising by operation of Law, by contract, pursuant to
               the Employee Plans, by past custom or practice or otherwise,
               for salary, severance, vacation and holiday pay, bonuses and
               other forms of compensation which were payable to the
               Therapeutic Asset Employees for the period ending prior to the
               Closing Date, have been paid as of the applicable payment
               dates.

         (v)   Collective Agreements.  None of the Vendors nor their Affiliates

               association with respect to any of its employees (including any

               Affiliates has made commitments to or conducted negotiations with

               member of the IBEX Group, there are no current attempts to
               organize or to establish any labour union or employee association
               with respect to the Therapeutic Asset Employees.

         (w)   Labour Matters.  There are no controversies pending or to the
               Best Knowledge of each Vendor, threatened between any member of

               Asset Employees.

               insurance, issued by responsible insurers, as are appropriate to
               the IBEX Group Worldwide Business and the Worldwide Assets, in
               such amounts and against such risks as are customarily carried
               and insured against by owners of comparable businesses,

               terms of any such policy. All of such policies are listed in
               Schedule 5.1(x). All premiums in connection with such policies
               are fully paid. None of the Vendors has failed to give any notice
               or present any Claim under any such insurance policies in due and
               timely fashion. The proceeds of such policies are and until

               of the Vendors is in default with respect to any of the
               provisions contained in such insurance policies and none of the
               Vendors have failed to give any notice or present any claim under

               conducted and will continue to be conducted through Closing in
               accordance with all applicable Laws and Governmental Orders,
               except where the failure to comply with such Laws and
               Governmental Orders would not have a material adverse effect on
               the Worldwide Assets or the condition, operations or prospects of
               the IBEX Group Worldwide Business and the Vendors have not
               received any notice in writing and, to the Actual Knowledge of

                                      -28-



         (b)   Such Vendor knows of no public solicitation or
               advertisement of an offer in connection with the BioMarin
               Worldwide Transaction Shares.

         (c)   Such Vendor has carefully reviewed this Agreement. During the
               course of the Worldwide Transaction and prior to the purchase of
               the BioMarin Worldwide Transaction Shares, such Vendor has had
               the opportunity to ask questions of and receive answers from
               BioMarin concerning the terms and conditions of the Worldwide
               Transaction and to obtain additional information concerning the
               Worldwide Transaction, BioMarin and the BioMarin Worldwide
               Transaction Shares. Such Vendor has received all information that
               it has requested regarding BioMarin and believes that such
               information is sufficient to make an informed decision with
               respect to the purchase of the BioMarin Worldwide Transaction
               Shares.

         (d)   Such Vendor is able to bear the economic risk of its
               investment in the BioMarin Worldwide Transaction Shares and
               has such knowledge and experience in financial and business
               matters that it is capable of evaluating the merits and risks
               of and protecting its interests with respect to its investment
               in the BioMarin Worldwide Transaction Shares. Such Vendor is
               aware of the risk involved in its investment in the BioMarin
               Worldwide Transaction Shares and has determined that such
               investment is suitable for such Vendor in light of its
               financial circumstances and available investment
               opportunities.

         (e)   Such Vendor is an "accredited investor" as that term is
               defined in Rule 501 of Regulation D promulgated under the
               Securities Act.

         (f)   The purchase by such Vendor of the BioMarin Worldwide
               Transaction Shares hereunder does not violate or conflict with
               any Law applicable to such Vendor.

         (g)   Each Vendor hereby further agrees with BioMarin that
               the instruments or certificates evidencing the BioMarin
               Worldwide Transaction Shares and each instrument or
               certificate issued in transfer thereof will bear the following
               legend:

                           "The securities evidenced by this certificate have
                           not been registered under the Securities Act of 1933
                           and have been taken for investment purposes only and
                           not with a view to the distribution thereof, and,
                           except as stated in an agreement between the holder
                           of this certificate, or its predecessor in interest,
                           and the issuer corporation, such securities may not
                           be sold or transferred unless there is an effective
                           registration statement under such Act covering such
                           securities or the issuer corporation receives an
                           opinion, in form and content reasonably satisfactory
                           to the issuer corporation, of counsel reasonably






























                                      -29-



                           acceptable to the issuer corporation (which may be
                           counsel for the issuer corporation) stating that such
                           sale or transfer is exempt from the registration and
                           prospectus delivery requirements of such Act."

         (h)   The instruments or certificates representing the
               BioMarin Worldwide Transaction Shares and each instrument or
               certificate issued in transfer thereof will also bear any
               legend required under any applicable state securities law.

         (i)   Prior to any proposed sale, assignment, transfer or pledge of any
               of the BioMarin Worldwide Transaction Shares by such Vendor,
               unless there is in effect a registration statement under the
               Securities Act covering the proposed transfer, such Vendor
               shall give written notice to BioMarin of such Vendor's
               intention to effect such transfer, sale, assignment or
               pledge. Each such notice shall describe the manner and
               circumstances of the proposed transfer, sale, assignment or
               pledge in sufficient detail and shall be accompanied, at
               such Vendor's expense, by an unqualified written opinion of
               legal counsel who shall and whose legal opinion shall be
               reasonably satisfactory to BioMarin addressed to BioMarin
               (which may be counsel for BioMarin), to the effect that the
               proposed transfer of the BioMarin Worldwide Transaction
               Shares may be effected without registration under the
               Securities Act, whereupon the holder of such BioMarin
               Worldwide Transaction Shares shall be entitled to transfer
               such BioMarin Worldwide Transaction Shares in accordance
               with the terms of the notice delivered by such Vendor to
               BioMarin.

         (j)   Such Vendor consents to BioMarin's making a notation on
               its records or giving instructions to any transfer agent of
               its common stock in order to implement the restrictions on
               transfer of the BioMarin Worldwide Transaction Shares
               mentioned above.

         (k)   Such Vendor is aware that the BioMarin Worldwide
               Transaction Shares are being issued and sold in reliance on an
               exemption from the registration requirements of the Securities
               Act and that such exemption is expressly conditioned on the
               accuracy of the representations and warranties contained in
               this section 5.2.

         (l)   Such Vendor is not a company established solely to acquire the
               BioMarin Worldwide Transaction Shares.

         (m)   Such Vendor has been independently advised as to restrictions
               with respect to the trading in the BioMarin Worldwide
               Transaction Shares in Canada imposed by applicable Canadian
               securities legislation, confirms that: (i) no representation
               has been made to it by or on behalf of BioMarin; (ii)
               BioMarin is not a "reporting issuer" in any jurisdiction in
               Canada; (iii) the applicable "hold period", under the
               applicable securities law of Canada will not commence until






























                                      -30-



               BioMarin becomes a "reporting issuer" in the province of
               residence of such Vendor and such Vendor will not be able to
               resell the BioMarin Canadian Transaction Shares except in
               accordance with limited exemptions under applicable
               securities legislation and regulatory policy; and (iv) the
               BioMarin Worldwide Transaction Shares will be subject to
               resale restrictions.

7.       Registration of BioMarin Worldwide Transaction Shares

7.1      Required Registration.

         (a)   Within five days following the Closing Date, BioMarin shall
               prepare and file a registration statement on Form S-3 under the
               Securities Act, covering the BioMarin Worldwide Transaction
               Shares and shall use its best efforts to cause such registration
               statement to become effective as expeditiously as possible and to
               remain effective until the earliest to occur of: (i) the date the
               BioMarin Worldwide Transaction Shares covered thereby have been
               sold; (ii) the date by which all BioMarin Worldwide Transaction
               Shares covered thereby may be sold under Rule 144 without
               restriction as to volume; or (iii) the date which is the
               twenty-fourth month anniversary of the Closing Date.

         (b)   Following the effectiveness of a registration statement filed
               pursuant to this section, BioMarin may at any time suspend the
               effectiveness of such registration for up to 60 days, as
               appropriate (a "Suspension Period"), by giving notice to the
               Vendors, if BioMarin shall have determined that BioMarin may be
               required to disclose any material corporate development which
               disclosure may have a Material Adverse Effect on BioMarin.
               Notwithstanding the foregoing, no more than two Suspension
               Periods may occur during any 12 month period. BioMarin shall use
               its best efforts to limit the duration and number of any
               Suspension Periods. The Vendors agree that upon receipt of any
               notice from BioMarin of a Suspension Period, the Vendors shall
               forthwith discontinue disposition of BioMarin Worldwide
               Transaction Shares covered by such registration statement or
               prospectus until the Vendors: (i) are advised in writing by
               BioMarin that the use of the applicable prospectus may be
               resumed; (ii) have received copies of a supplemental or amended
               prospectus, if applicable; and (iii) have received copies of any
               additional or supplemental filings which are incorporated or
               deemed to be incorporated by reference into such prospectus.

7.2      Registration Procedures.  At such time as BioMarin effects the
         registration of the BioMarin Worldwide Transaction Shares under the
         Securities Act pursuant to section 7.1(a) BioMarin will, at its expense
         and as expeditiously as possible;

         (a)   In accordance with the Securities Act and the rules and
               regulations of the Commission, prepare and file in
               accordance with section 7.1(a) a registration statement with

               statement to become and remain effective for the period
               described herein and BioMarin will prepare and file with the
               Commission such amendments to such registration statement
               and supplements to the prospectus contained therein as may
               be necessary to keep such registration statement effective
               for such period and such registration statement and
               prospectus accurate and complete for such period.

         (b)   Furnish to the Vendors participating in such registration such
               reasonable number of copies of the registration statement,
               preliminary prospectus, final prospectus and such other
               documents as such Vendors may reasonably request in order to
               facilitate the public offering of the BioMarin Worldwide
               Transaction Shares.

         (c)   Use its best efforts to register or qualify the BioMarin
               Worldwide Transaction Shares covered by such registration
               statement under such state securities or blue sky laws of
               such jurisdictions as such participating Vendors may
               reasonably request within 20 days following the original
               filing of such registration statement, except that BioMarin
               shall not for any purpose be required to execute a general
               consent to service of process or to qualify to do business
               as a foreign corporation in any jurisdiction where it is not
               so qualified.

         (d)   Notify the Vendors participating in such registration,
               promptly after BioMarin shall receive notice thereof, of the
               date and time when such registration statement and each
               post-effective amendment thereto has become effective or a
               supplement to any prospectus forming a part of such
               registration statement has been filed.

         (e)   Notify such Vendors promptly of any request by the
               Commission for the amending or supplementing of such
               registration statement or prospectus or for additional
               information.

         (f)   Prepare and file with the Commission, promptly upon the
               request of any such Vendors, any amendments or supplements to
               such registration statement or prospectus which, in the
               opinion of counsel for such Vendors, is required under the
               Securities Act or the rules and regulations thereunder in
               connection with the distribution of the BioMarin Worldwide
               Transaction Shares by such Vendors.

         (g)   Prepare and promptly file with the Commission and
               promptly notify such Vendors of the filing of, such amendments
               or supplements to such registration statement or prospectus as
               may be necessary to correct any statements or omissions if at
               the time when a prospectus relating to such securities is
























                                      -35-



               required to be delivered under the Securities Act any event
               has occurred as the result of which any such prospectus or any
               other prospectus as then in effect would include an untrue
               statement of a material fact or omit to state any material
               fact required to be stated therein or necessary to make the
               statements therein not misleading.

         (h)   Advise such Vendors, promptly after BioMarin shall
               receive notice or obtain knowledge thereof, of the issuance of
               any stop order by the Commission suspending the effectiveness
               of such registration statement or the initiation or
               threatening of any proceeding for that purpose and promptly
               use its best efforts to prevent the issuance of any stop order
               or to obtain its withdrawal if such stop order should be
               issued.

7.3  Covenant Regarding Disposition of BioMarin Shares.  Following the
effectiveness of a registration statement filed pursuant to section 7.1, and
without limitation of the provisions of section 7.1(b), the Vendors jointly and
severally covenant and agree that any disposition of the BioMarin Worldwide
Transaction Shares shall be made in a manner that does not unduly prejudice the
trading price of BioMarin's common stock on the Nasdaq National Market or the
SWX Swiss Market.

7.4      Indemnification.

         (a)   BioMarin will indemnify and hold harmless each Vendor which is an
               owner of shares of BioMarin Worldwide Transaction Shares included
               in a registration statement pursuant to the provisions of Article
               7 hereof, and any officer, director, employee, agent, partner,
               member or affiliate of such Vendor (for purposes of this section
               7.4(a), the "Indemnified Parties"), from and against, and will
               reimburse such Vendor and each such Indemnified Party with
               respect to, any and all claims, actions, demands, losses,
               damages, liabilities, costs and expenses to which such Vendor or
               any such Indemnified Party may become subject under the
               Securities Act or otherwise, insofar as such claims, actions,
               demands, losses, damages, liabilities, costs or expenses arise
               out of or are based upon any untrue statement or alleged untrue
               statement of any material fact contained in such registration
               statement, any prospectus contained therein or any amendment or
               supplement thereto, or arise out of or are based upon the
               omission or alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements









































                                      -36-



               therein not misleading; provided, however, that BioMarin will not
               be liable in any such case to the extent that any such claim,
               action, demand, loss, damage, liability, cost or expense is
               caused by an untrue statement or alleged untrue statement or
               omission or alleged omission so made in conformity with
               information furnished by such Vendor or such Indemnified Party in
               writing specifically for use in the preparation thereof.

         (b)   Each Vendor which is an owner of shares of BioMarin  Worldwide
               Transaction Shares included in a registration statement pursuant
               to the provisions of Article 7 hereof will indemnify and hold
               harmless BioMarin, and any Person who controls BioMarin within
               the meaning of the Securities Act, from and against, and will
               reimburse BioMarin and such controlling Persons with respect to,
               any and all losses, damages, liabilities, costs or expenses to
               which BioMarin or such controlling Person may become subject
               under the Securities Act or otherwise, insofar as such losses,
               damages, liabilities, costs or expenses are caused by any untrue
               or alleged untrue statement of any material fact contained in
               such registration statement, any prospectus contained therein or
               any amendment or supplement thereto, or are caused by the
               omission or the alleged omission to state therein a material fact
               required to be stated therein or necessary to make the statements
               therein, in light of the circumstances in which they were made,
               not misleading, in each case to the extent, but only to the
               extent, that such untrue statement or alleged untrue statement or
               omission or alleged omission was so made solely in reliance upon
               and in conformity with written information furnished by such
               Vendor specifically for use in the preparation thereof; provided,
               however, that the liability of any Vendor pursuant to this
               subsection (b) shall be limited to an amount not to exceed the
               net proceeds received by such Vendor pursuant to the registration
               statement which gives rise to such obligation to indemnify.

         (c)   Promptly after receipt by a party indemnified pursuant to the
               provisions of paragraph (a) or (b) of this section 7.4 of notice
               of the commencement of any action involving the subject matter of
               the foregoing indemnity provisions, such indemnified party will,
               if a claim thereof is to be made against the indemnifying party
               pursuant to the provisions of paragraph (a) or (b), notify the
               indemnifying party of the commencement thereof; but the omission
               so to notify the indemnifying party will not relieve it from any
               liability which it may have to an indemnified party otherwise
               than under this section 7.4 and shall not relieve the
               indemnifying party from liability under this section 7.4 unless
               such indemnifying party is prejudiced by such omission. In case
               such action is brought against any indemnified party and it
               notifies the indemnifying party of the commencement thereof, the
               indemnifying party shall have the right to participate in, and,
               to the extent that it may wish, jointly with any other
               indemnifying party similarly notified, to assume the defense
               thereof, with counsel reasonably satisfactory to such indemnified
               party, and after notice from the indemnifying party to such
               indemnified party of its election so to assume the defense































                                      -37-



               thereof, the indemnifying party will not be liable to such
               indemnified party pursuant to the provisions of such paragraph
               (a) or (b) for any legal or other expense subsequently incurred
               by such indemnified party in connection with the defense thereof
               other than reasonable costs of investigation. No indemnifying
               party shall be liable to an indemnified party for any settlement
               of any action or claim without the consent of the indemnifying
               party. No indemnifying party will consent to entry of any
               judgment or enter into any settlement which does not include as
               an unconditional term thereof the giving by the claimant or
               plaintiff to such indemnified party of a release from all
               liability in respect to such claim or litigation.

         (d)   If the indemnification provided for in subsection (a) or (b) of
               this section 7.4 is held by a court of competent jurisdiction to
               be unavailable to a party to be indemnified with respect to any
               claims, actions, demands, losses, damages, liabilities, costs or
               expenses referred to therein, then each indemnifying party under
               any such subsection, in lieu of indemnifying such indemnified
               party thereunder, hereby agrees to contribute to the amount paid
               or payable by such indemnified party as a result of such claims,
               actions, demands, losses, damages, liabilities, costs or expenses
               in such proportion as is appropriate to reflect the relative
               fault of the indemnifying party on the one hand and of the
               indemnified party on the other in connection with the statements
               or omissions which resulted in such claims, actions, demands,
               losses, damages, liabilities, costs or expenses, as well as any
               other relevant equitable considerations. The relative fault of
               the indemnifying party and of the indemnified party shall be
               determined by reference to, among other things, whether the
               untrue or alleged untrue statement of a material fact or the
               omission or alleged omission to state a material fact relates to
               information supplied by the indemnifying party or by the
               indemnified party and the parties' relative intent, knowledge,
               access to information and opportunity to correct or prevent such
               statement or omission. The amount any Vendor shall be obligated
               to contribute pursuant to this subsection (d) shall be limited to
               an amount not to exceed the net proceeds received by such Vendor
               pursuant to the registration statement which gives rise to such
               obligation to contribute. No person guilty of fraudulent
               misrepresentation (within the meaning of section 11(f) of the
               Securities Act) shall be entitled to contribution hereunder from
               any person who was not guilty of such fraudulent
               misrepresentation.


8.       SURVIVAL OF REPRESENTATIONS AND WARRANTIES

8.1  Survival.  No investigations made by or on behalf of any Party at any
time shall have the effect of waiving, diminishing the scope of or otherwise
affecting any representation or warranty made by any Party. No waiver by any


































                                      -38-



Party of any condition, in whole or in part, shall operate as a waiver of any
other condition. The representations and warranties contained in Article 5 and 6
respectively or in any certificate or other document delivered in connection
with the Closing shall survive the making of this Agreement and the Closing as
to the representations and warranties contained in section 5.1(g), 5.1(l),
5.1(y) and 5.1(bb), for a period of six years and as to all other
representations and warranties, for a period of three years following the
Closing unless a bona fide notice of a Claim shall have been given in writing
prior to the expiry of that period, in which case the representations and
warranties to which such notice applies shall survive in respect of that Claim
until the final determination or the applicable settlement, in each case, of
that Claim.


9.       COVENANTS

9.1  Interim Covenants.  From the date hereof and up to and including the
Closing Date or other termination of this Agreement, except as otherwise

               shall preserve their relationships with customers, suppliers
               and third Persons having business dealings with the Vendors
               and shall take any and all such further actions reasonably
               requested by the members of the BioMarin Group to the end that
               the IBEX Group Worldwide Business shall not be impaired in any
               material respect on the Closing Date.

         (b)   Insurance. The Vendors shall keep in full force their
               current insurance policies relating to the Worldwide Assets
               and the IBEX Group Worldwide Business without permitting any
               termination, cancellation or lapse thereof and the Vendors
               shall enter into replacement policies providing coverage equal
               to or greater than the coverage under those cancelled,
               terminated or lapsed policies for substantially similar
               premiums.

         (c)   Contracts. The Vendors shall perform in all material
               respects their respective obligations under Contracts relating

         (e)   Compliance With Laws.  The Vendors shall comply in all material
               respects with all Laws applicable to the Worldwide Assets and/or
               the IBEX Group Worldwide Business.































                                      -39-



         (f)   Additional Contracts.  No member of the IBEX Group or their
               Affiliates shall enter into or assume any Contract relating to
               the IBEX Group Worldwide Business except for; (i) purchases of
               supplies or inventories in the usual and ordinary course of the
               IBEX Group Worldwide Business consistent with prior practice; and
               (ii) Contracts which, individually or in the aggregate, are not
               material to the IBEX Group Worldwide Business. For purposes of
               the proceeding sentence, any Contract in excess of Cdn.$50,000
               shall be considered material to the IBEX Group Worldwide
               Business. No member of the IBEX Group or their Affiliates shall
               otherwise make any material change in the conduct of the IBEX
               Group Worldwide Business.

         (g)   Disposition of Worldwide Assets. The Vendors shall not
               sell, lease or transfer or agree to sell, lease or transfer or
               cause any Encumbrance upon, any of the Worldwide Assets, out
               of the ordinary course of business or approve or undertake any
               other transaction out of the ordinary course of business or
               furnish or cause to be furnished any information concerning
               the Worldwide Assets and/or the IBEX Group Worldwide Business
               to any third Person who is interested in any such transaction.

         (h)   Representations and Warranties. The members of the IBEX
               Group shall not do anything that would cause any of the
               representations and warranties under Article 5 to be false,
               incomplete or misleading in such a fashion as to have a
               Material Adverse Effect on the members of the IBEX Group.

         (i)   Advice. The members of the IBEX Group shall promptly
               advise the members of the BioMarin Group in writing of any

               condition, financial or otherwise of the Worldwide Assets
               and/or the IBEX Group Worldwide Business.

         (j)   Accounting. With respect to the IBEX Group Worldwide
               Business and the Worldwide Assets, no member of the IBEX Group

               records or practices followed by it or depreciation or
               amortization policies or rates theretofore adopted by it. Each
               member of the IBEX Group shall maintain its books, records and
               accounts in accordance with Canadian generally accepted
               accounting principles applied on a basis consistent with past
               practice.

         (k)   Discharge. No member of the IBEX Group shall cancel,
               compromise, release or discharge any Claim in connection with
               the operations of the Worldwide Assets upon or against any
               Person or waive any right of material value except, in any
               case, in the ordinary course of the IBEX Group Worldwide
               Business and consistent with past practice.

         (l)   McGill License. The members of the IBEX Group shall,
               upon the request of BioMarin, introduce representatives of
               BioMarin to appropriate representatives of McGill University

               use US Patent 5,147,641 and its foreign counterparts on
               substantially the same terms and conditions as the license

               negotiation of such license by BioMarin.

"Representatives") all title documents, policies of insurance, Contracts and
other documents in the possession of the members of the IBEX Group or under the
control of the members of the IBEX Group relating to the Worldwide Assets and

Group contained in this Agreement; (ii) any Action arising from rights of
creditors pursuant to the Bulk Sales Carve-Out or any Action arising from rights
of creditors pursuant to any non-compliance by BioMarin US with section 1767 ss
of the Civil Code of Quebec in connection with the Worldwide Transaction or the
Vendor's or BioMarin US's failure to comply with applicable bulk sales or sale
of an enterprise legislation; (iii) any Excluded Liability; (iv) any Action
arising out of or resulting from the conduct of the IBEX Group Worldwide
Business or any of the Worldwide Assets by the members of the BioMarin Group
prior to the Closing Date; and (v) any Action arising from the failure of the
members of the IBEX Group to comply with any covenants contained in this
Agreement.

10.3  Indemnification Procedure.  An indemnified party pursuant to the
provisions hereof (the "Indemnified Party") shall give the other Party (the
"Indemnitor") notice of any matter which an Indemnified Party has determined has
given or could give rise to a right of indemnification under this Agreement,
within 60 days of such determination, stating the amount of the Loss if known
and the method of computation thereof and containing a reference to the
provisions of this Agreement in respect of which such right of indemnification
is claimed. If an Indemnified Party shall receive notice of any third party
claim (a "Third Party Claim"), the Indemnified Party shall give the Indemnitor
notice of the Third Party Claim within 30 days of the receipt by the Indemnified
Party of such notice. The failure to provide such notice shall not release the
Indemnitor from its obligations under this Article except to the extent that the
Indemnitor is materially prejudiced by such failure and shall not relieve the
Indemnitor from any other obligation or liability that it may have to the
Indemnified Party other than under this Article. If the Indemnitor acknowledges
in writing its obligation to indemnify the Indemnified Party hereunder against
any Losses that may result from such Third Party Claim within 20 days of receipt
of notice of such Claim, the Indemnitor shall be entitled to assume and control
the defense of such Third Party Claim at its expense and through counsel of its
choice if it gives notice of its intention to do so to the Indemnified Party
within five days of the receipt of such notice from the Indemnified Party. If
there exists or is reasonably likely to exist a conflict of interest that would
make it inappropriate in the judgment of the Indemnified Party, in its sole and
absolute discretion, for the same counsel to represent both the Indemnified
Party and the Indemnitor or if the Indemnitor does not so assume and defend such
Third Party Claim, the Indemnified Party shall be entitled to retain its own
counsel, in each jurisdiction for which the Indemnified Party determines counsel
is required, at the expense of the Indemnitor. If the Indemnitor exercises the
right to undertake any such defense against any Third Party Claim, the
Indemnified Party shall cooperate with the Indemnitor in such defense and shall
make available to the Indemnitor, at the Indemnitor's expense, all witnesses,
pertinent records, materials and information in the Indemnified Party's
possession or under the Indemnified Party's control relating thereto as is
reasonably required by the Indemnitor. If the Indemnified Party is directly or
indirectly conducting the defense against any such Third Party Claim, the
Indemnitor shall cooperate with the Indemnified Party in such defense and shall
make available to the Indemnified Party, at the Indemnitor's expense, all such
witnesses, records, materials and information in the Indemnitor's possession or
under the Indemnitors' control relating thereto as is reasonably required by the


































                                      -42-



Indemnified Party. No such Third Party Claim may be settled by the Indemnitor
without the prior written consent of the Indemnified Party, acting reasonably.
For the purposes of this Article 10, the members of the BioMarin Group shall be
treated as one Party and the members of the IBEX Group shall be treated as one
Party.

10.4  Supplemental Rights.  The rights and benefits provided in this Article
10 are supplemental to and are without prejudice to any other rights, actions or
causes of action which may arise pursuant to any other section of this Agreement
or pursuant to applicable law.

10.5  Reduction of Worldwide Purchase Price.  All amounts received by the
members of the  BioMarin  Group pursuant to the provisions of this Article shall
be received in reduction of the Worldwide Purchase Price.

10.6  Minimum and Maximum Indemnification Claim.  Notwithstanding the
provisions of section 10.1(i) and (ii) or 10.2(i) and (iv), as the case may be,
the obligation of the members of the BioMarin Group or the members of the IBEX
Group, as the case may be, to indemnify the other Parties in respect of any of
the matters described therein, as the case may be, shall become applicable only
when the Losses actually incurred by the Person entitled to indemnification
exceed in the aggregate Cdn.$100,000 under this Agreement and/or the Canadian
Purchase Agreement (the "Minimum Threshold"). Once the Minimum Threshold has
been exceeded, the obligations of indemnification with respect to such matters
shall apply to: (i) 50% of any and all Losses from dollar one above Cdn. $50,000
to Cdn. $100,000; and (ii) any and all Losses from dollar one above Cdn.$100,000
of such Losses. The right of indemnification with respect to such matters shall
only apply to Losses (exclusive of Losses relating to breaches of
representations and warranties set forth in sections 5.1(l) and 5.1(bb), and any
other matters relating to the Excluded Liabilities and rights of creditors
pursuant to the Bulk Sales Carve-Out and rights of creditors pursuant to matters
described in section 10.2(ii), for which there shall be no limitation) under
this Agreement and the Canadian Purchase Agreement which aggregate up to and
including the sum of (a) the Canadian Purchase Price (as defined in the Canadian
Purchase Agreement), (b) the Worldwide Purchase Price and (c) the Contingency
Payments.

10.7  Rights of Set-Off.  Subject to section 10.6, in the event the members
of the BioMarin Group have incurred Losses and the members of the IBEX Group
must indemnify the members of the BioMarin Group pursuant to the provisions
hereof, BioMarin shall have the right to set off such Losses including, without
limitation, any Losses of the BioMarin Group under the Canadian Purchase
Agreement, as against the Contingency Payments.

reasonably capable of being performed or caused to be performed by the members
of the IBEX Group and are the obligation of the members of the IBEX Group to
perform or to cause to be performed or have not been satisfied by reason of a

part by the members of the BioMarin Group without prejudice to the members of

13.      THIRD PARTY ASSIGNMENT AND CONSENTS

13.1  Third Party Assignments.  Neither this Agreement nor any Closing
Document shall constitute an assignment or an attempted assignment of any
Worldwide Assigned Right contemplated to be assigned to BioMarin US hereunder
where such Worldwide Assigned Right; (i) is not assignable without the consent
of a third Person if such consent has not been obtained and such assignment or
attempted assignment would constitute a breach thereof; or (ii) in respect of
which Worldwide Assigned Right the remedies for enforcement thereof available to
the Vendors would not pass to BioMarin US. In respect of the foregoing, the
members of the IBEX Group, as and by way of a post-closing covenant, jointly and
severally agree to take such action or cause to be taken such action in their
own name or otherwise as the members of the BioMarin Group shall reasonably
require so as to provide BioMarin US the benefits thereof and to effect
collection of money to become due and payable by the other party thereto and the
members of the IBEX Group shall promptly pay over to BioMarin US all money
received by the Vendors in respect of the foregoing. If and when any Worldwide
Assigned Right Consent is obtained or such Worldwide Assigned Right otherwise
becomes assignable, the Vendors shall promptly assign all of their rights and
obligations thereunder to BioMarin US and BioMarin US shall, without the payment
of any further consideration therefor, assume such rights and obligations and
the Vendors shall be relieved of any and all liability therefor.

Notwithstanding the foregoing, it is acknowledged and agreed that (x) no

reasonably concluded by a Party to be required by applicable Law. The forms of
press release to be issued by IBEX and BioMarin upon the execution and delivery
of this Agreement are set forth in Schedule 15.2. Each member of the IBEX Group

continued with the members of the IBEX Group or any of their Affiliates or
Representatives; provided however that nothing contained in this section shall
prohibit the board of directors of IBEX from furnishing non-public information
to or entering into discussions or negotiations with any Person that makes an

determines in good faith that such action is required for the board of directors
of IBEX to comply with its fiduciary duties to shareholders imposed by
applicable Law; (ii) prior to furnishing such information to or entering into

agreement with any Person that provides for or in any way facilitates an
Acquisition Proposal or affect any other obligation of the members of the IBEX

Schedule 2.2: IBEX Pharma Canadian Assumed Liabilities

--------------------------------------------------------------------------------

None, except in respect of severance obligations to the Therapeutic Asset
Employees as set forth in Section 2.3 of the Canadian Asset Purchase Agreement.



Schedule 2.3 - IBEX Group Severance Practices

This policy will provide guidelines in determining severance allocations for
IBEX employees in the case of mass layoffs due to restructuring, downsizing,
mergers, or take-offers. Employees terminated for cause will not be entitled to
the same benefits.

---------------------------------------------------------------------------------------------------------------------


Senior employees such as supervisors, and group leaders typically receive an
additional 2 - 3 months depending on their age and functions (taking into
consideration the ease of finding equivalent employment).

When calculating severance payments, factors that need to be added include
vacation pay, RRSP contribution, health and dental insurance.

Employees have three options when they are given a termination letter.

1.   They can remain in the  employment  of the  company  for the full period of
     notice;
2.   They can give 2-4  weeks  notice  (depending  on the  position  held by the
     individual)  and take 60% of the  balance  of the  notice  period in a cash
     settlement;
3.   They can take a combination of both.

We have been able to justify a longer-than-normal period of notice on the basis
that during the period that employees are employed by IBEX we can claim a 40%
rebate from the Quebec government. This has allowed us to stretch the dollars
further than we otherwise could if we used the same net amount as cash
severance. In the event employees wish to take a cash settlement, a 60% rule
will apply.

Lets take the case of an employee who has received 23 weeks notice on December
8th:

IBEX requires a three week notice to wrap up any outstanding matters. If that
employee were to leave December 31, 1999 he or she would be paid through the
next three weeks and would have 20 weeks remaining of the notice period. If that
employee wanted to take severance instead of notice we would only be able to
provide 60% of that 20 weeks or 12 weeks lump sum payment (plus whatever
vacation pay etc that was due)

Similarly, someone who has received 23 weeks notice and wants to leave at the
end of January would have 7 weeks notice and 60% of the remaining 16 weeks (i.e.
9.6 weeks) in cash.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Stockholders of
BioMarin Pharmaceutical Inc.:

We have  audited  the  accompanying  consolidated  balance  sheets  of  BioMarin
Pharmaceutical  Inc.  (a  Delaware  corporation  in the  development  stage) and
subsidiaries  as of  December  31,  1999 and 2000 and the  related  consolidated
statements of operations,  changes in stockholders'  equity,  and cash flows for
the years ended  December 31, 1998,  1999 and 2000 and the period from March 21,
1997  (inception)  to December  31, 2000.  These  financial  statements  are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States. Those standards require that we plan and perform the audit
to obtain reasonable  assurance about whether the financial  statements are free
of material misstatement. An audit includes examining, on a test basis, evidence
supporting  the amounts and  disclosures in the financial  statements.  An audit
also includes assessing the accounting principles used and significant estimates
made by  management,  as well as  evaluating  the  overall  financial  statement
presentation.  We believe  that our audits  provide a  reasonable  basis for our
opinion.

In our opinion,  the financial  statements  referred to above present fairly, in
all material respects,  the financial position of BioMarin  Pharmaceutical  Inc.
and  subsidiaries  as of  December  31,  1999 and 2000 and the  results of their
operations and their cash flows for the years ended December 31, 1998,  1999 and
2000 and the period from March 21, 1997  (inception)  to December 31,  2000,  in
conformity with accounting principles generally accepted in the United States.

                  BioMarin Pharmaceutical Inc. and Subsidiaries
                          (a development-stage company)

                   Notes to Consolidated Financial Statements

1.   NATURE OF OPERATIONS AND BUSINESS RISKS:


BioMarin  Pharmaceutical  Inc.  (the  Company)  is a  biopharmaceutical  company
specializing   in  the   development  of  enzyme   therapies  for   debilitating
life-threatening  chronic  genetic  diseases and other diseases and conditions.
Since  inception,  the Company has devoted  substantially  all of its efforts to
research and development activities,  including preclinical studies and clinical
trials,   the  establishment  of  laboratory,   clinical  and  commercial  scale
manufacturing  facilities,  clinical  manufacturing,  and related administrative
activities.

The Company was  incorporated  on October 25, 1996 in the state of Delaware  and
first began business on March 21, 1997 (inception) as a wholly-owned  subsidiary
of Glyko  Biomedical  Ltd.  (GBL).  Subsequently,  BioMarin  has issued stock to
outside  investors in a series of transactions,  resulting in GBL's ownership of
BioMarin's  outstanding common stock being reduced to 31 percent at December 31,
2000.

On October 7, 1998, the Company acquired Glyko, Inc., a wholly-owned  subsidiary
of GBL, in a transaction valued at $14.5 million.  The transaction was accounted
for as a purchase and resulted in Glyko, Inc. becoming a wholly-owned subsidiary
of the  Company.  Glyko,  Inc.  provides  products  and  services  that  perform
sophisticated  carbohydrate  analysis for research  institutions  and commercial
laboratories.

Through  December  31,  2000,  the Company  had  accumulated  losses  during its
development  stage of  approximately  $80.5  million.  Based on  current  plans,
management  expects to incur further  losses at least  through 2002.  Management
believes that the Company's cash and cash equivalents and short-term  investment
balances  at  December  31,  2000  will  be  sufficient  to meet  the  Company's
obligations at least through 2001.

Business Risks - The Company is exposed to the following risks:

o        There can be no assurance that the Company's  research and  development
         efforts will be successfully  completed or that its product  candidates
         will be shown to be safe and effective.

o        There can be no assurance that its product  candidates will be approved
         for  marketing by the U.S.  Food and Drug  Administration  (FDA) or any
         equivalent  foreign  government  agency or that its product  candidates
         will be successfully  commercialized or achieve any significant  degree
         of market acceptance.

o        Certain  of the  Company's  products  and  product  candidates  rely on
         proprietary  technology and patents owned by certain  universities  and
         other  institutions and licensed to BioMarin.  These  universities also
         provide research and development  services.  Cessation of relationships
         with these universities could significantly affect the Company's future
         operations.

o        In order to grow significantly,  the Company must expand its efforts to
         develop new products in pharmaceutical  applications.  The Company will
         also need to enhance manufacturing  capabilities,  to develop marketing
         capabilities,  and/or enter into collaborative  arrangements with third
         parties having the capacity for such manufacturing or marketing.

o        There can be no assurance  that any of the Company's  current or future
         product  candidates  will  be  successfully  developed,   prove  to  be
         effective in clinical trials, receive required regulatory approvals, be
         capable of being produced in commercial quantities at reasonable costs,
         gain reasonable reimbursement levels, or be successfully marketed.

In addition, the Company is subject to a number of risks, including the need for
additional  financing,  dependence on key personnel,  small patient  population,
patent protection, significant competition from larger organizations, dependence
on  corporate   partners  and  collaborators,   and  expected   restrictions  on
reimbursement, as well as other changes in the healthcare industry.

2.       SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES:

Basis of  Presentation--These  consolidated  financial  statements  include  the
accounts of BioMarin,  Glyko, Inc., a wholly-owned subsidiary of BioMarin (since
October 7, 1998),  and BioMarin  Genetics,  Inc., a  wholly-owned  subsidiary of
BioMarin  formed for the purpose of the joint  venture  discussed in Note 8. All
significant intercompany transactions have been eliminated.

Concentration of Credit Risk--Financial instruments that may potentially subject
the Company to  concentration  of credit risk consist  principally of cash, cash
equivalents,  and  short-term  investments.  All  cash,  cash  equivalents,  and
short-term  investments are placed in financial  institutions with strong credit
ratings, which minimizes the risk of loss due to nonpayment. The Company has not
experienced any losses due to credit  impairment or other factors related to its
financial instruments.

Use of  Estimates--The  preparation of financial  statements in conformity  with
generally accepted  accounting  principles  requires  management to make certain
estimates  and  assumptions  that  affect  the  reported  amounts  of assets and
liabilities, disclosure of contingent assets and liabilities at the dates of the
financial  statements,  and the reported amounts of revenues and expenses during
the  reporting  period.  Actual  results  could  differ  from  those  estimates.
Significant  estimates made by management  include  determination of progress to
date of research and development projects in-process, the amortization period of
goodwill and other intangibles, and asset impairment reserves related to certain
leasehold improvements and equipment.

Cash and Cash  Equivalents--For  the consolidated  statements of cash flows, the
Company treats liquid  investments  with original  maturities of less than three
months as cash and cash equivalents.

Short-Term Investments--The Company records its investments as held-to-maturity.
These investments are recorded at cost at December 31, 2000, which  approximates
fair market  value.  These  securities  are comprised  mainly of Federal  Agency
investments,   including   Freddie  Macs  and  Federal  Home  Loans,   and  bank
certificates of deposit.

Inventories--Inventories  consist of analytic kits and instrument-based  systems
held for sale. Inventories are stated at the lower of cost (first-in,  first-out
method) or estimated market value. All inventories at December 31, 1999 and 2000
belonged to Glyko, Inc.

Investment in BioMarin/Genzyme  LLC and Related  Revenue--Under the terms of the
Company's joint venture  agreement with Genzyme (the Agreement - see notes 7 and
8),  the  Company  and  Genzyme  have each  agreed to  provide 50 percent of the
funding  for  the  joint  venture.  All  research  and  development,  sales  and
marketing,  and other activities  performed by Genzyme and the Company on behalf
of the joint  venture  are billed to the joint  venture at cost.  Any profits or
losses of the joint venture are shared equally by the two parties. Losses of the
joint venture ($1.7 million,  $14.0 million, $25.3 million and $41.0 million for
the years ended  December 31,  1998,  1999 and 2000 and for the period March 21,
1997  (inception)  through  December 31, 2000,  respectively)  are  allocated in
proportion  to the funding  provided  by each joint  venture  partner.  BioMarin
provided $22.0 million in funding to the joint venture through 2000.

During the years ended  December  31, 1999 and 2000,  the Company  billed  $10.6
million  and  $19.4  million,  respectively,  to the  joint  venture  under  the
Agreement.  Of these amounts, $5.3 million and $9.7 million respectively,  or 50
percent,  was recognized as revenue in accordance  with the Company's  policy of
recognizing  revenue to the extent that research and development costs billed to
the joint  venture  have been funded by Genzyme.  At December 31, 1999 and 2000,
the Company had  receivables  of $1.3  million and $1.8  million,  respectively,
related to these billings.

The Company  accounts for its  investment  in the joint venture using the equity
method.  Accordingly,  the Company recorded a reduction in its investment in the
joint  venture of $7.0 and $12.7  million,  during the years ended  December 31,
1999 and 2000,  respectively,  representing  its 50 percent share of the loss of
the joint venture. The percentage of the research and development costs incurred
by the  Company and billed to the joint  venture  that was funded by the Company
(50 percent,  or $5.3 million and $9.7 million for the years ended  December 31,
1999 and 2000, respectively) was recorded as a credit to the Company's equity in
the loss of the joint venture.

At December 31, 2000 the summarized  assets and liabilities of the joint venture
and its results of operations from inception to December 31, 2000 are as follows
(in thousands):

 Assets                          $ 3,368

Cumulative net loss              $40,971
                                 =======

Research and Development--Research and development expenses include the expenses
associated  with contract  research and  development  provided by third parties,
research and development provided in connection with the joint venture including
manufacturing,   clinical  and  regulatory  costs,  and  internal  research  and
development  costs.  All  research and  development  costs  discussed  above are
expensed as incurred.

Property and  Equipment--Property and equipment are stated at cost. Depreciation
is computed using the straight-line method. Leasehold improvements are amortized
over the life of the  assets or the term of the  lease,  whichever  is  shorter.
Significant  additions  and  improvements  are  capitalized,  while  repairs and
maintenance are charged to expense as incurred.

As of December  31,  1999 and 2000,  property  and  equipment  consisted  of the

Depreciation  expense for the years ended  December 31, 1998,  1999 and 2000 and
for the period  March 21,  1997  (inception)  to  December  31,  2000,  was $0.3
million, $4.1 million, $4.3 million and $8.7 million, respectively.

Goodwill and Other  Intangible  Assets--In  connection  with the  acquisition of
Glyko, Inc., the Company acquired certain intangible assets including  developed
technology,  customer  relationships  and  goodwill.  In this  acquisition,  the
Company  obtained  Glyko  Inc.'s  ongoing  business of  providing  products  and
services to research institutions and commercial laboratories. Additionally, the
Company secured ongoing access to Glyko,  Inc.'s proprietary  technologies which
assist the Company in supporting the manufacturing  process testing and clinical
testing  for our two lead drug  candidates,  Aldurazyme  for MPS-I and rhASB for
MPS-VI.

The  purchase  price of $14.5  million was  allocated  to the net  tangible  and
intangible assets acquired, based on the relative fair value of these assets. In
connection with this  allocation,  $2.6 million was expensed as a charge for the
purchase of in-process research and development. Of the $11.7 million designated
as  intangible   assets   (after  the  write-off  of  in-process   research  and
development),  $1.2 million was allocated to developed  technology and amortized
over six years, $73,000 was allocated to assembled work force and amortized over
seven  years,   and  $10.4   million  was   allocated   to  goodwill   (customer
relationships,  trade name, pure business goodwill) and initially amortized over
twelve years. In performing this allocation, the Company considered, among other
factors,   Glyko,  Inc.'s  technology  and  research  and  development  projects
in-process at the date of  acquisition.  With regard to the in-process  research
and development  projects,  the Company  considered factors such as the stage of
development of the technology at the time of acquisition, the importance of each
project  to  the  overall  development  plan,  alternative  future  uses  of the
technology  and the  projected  incremental  cash flows from the  projects  when
completed and any associated risks.

During 2000 the Company changed its estimate of the useful life of this goodwill
from 12 years to 7 years.  The effect of this change in estimate was to increase
the Company's net loss by $466,000.

Amortization expense related to the acquisition of Glyko, Inc. was $0.3 million,
$1.1  million  and $1.6  million  for the period  from  October 7, 1998 (date of
acquisition)  to December  31, 1998,  and the years ended  December 31, 1999 and
2000, respectively.

In connection  with the purchase of the key assets of the  Biochemical  Research
Reagent  Division  of Oxford  GlycoSciences  Plc. (OGS),  the  Company  recorded
goodwill in the amount $891,000 which is being amortized over seven years. Total
amortization expense for the year ended December 31, 2000, was $139,000.

Impairment of Long-Lived Assets--The Company regularly reviews long-lived assets
and identifiable  intangibles whenever events or circumstances indicate that the
carrying  amount  of such  assets  may not be  fully  recoverable.  The  Company
evaluates  the  recoverability  of  long-lived  assets by measuring the carrying
amount of the  assets  against  the  estimated  undiscounted  future  cash flows
associated  with them.  At the time such  evaluations  indicate  that the future
undiscounted  cash flows of certain  long-lived  assets  are not  sufficient  to
recover the carrying value of such assets, the assets are adjusted to their fair
values (based on discounted cash flows). Except for the Carson Street closure as
discussed  in Note 11 no such  adjustments  have been  made  during  any  period
presented.

Revenue  Recognition--The  Company recognizes Glyko, Inc.'s product revenues and
related cost of sales upon shipment of products.  Glyko, Inc.'s service revenues
are recognized upon  completion of services as evidenced by the  transmission of
reports  to  customers.  Other  Glyko,  Inc.  revenues,  principally  licensing,
distribution  and  development   fees,  are  recognized  upon   satisfaction  of
contractual obligations such as 1) execution of contract; 2) certain milestones;
and 3) certain anniversary dates from the effective date of the contract.

Revenue from the joint  venture is  recognized  to the extent that  research and
development costs billed by the Company have been funded by Genzyme.

Net Income (Loss) per  Share--Basic net income (loss) per share is calculated by
dividing net income (loss) by the weighted  average  common  shares  outstanding
during the period.  Diluted net income per share is  calculated  by dividing net
income by the weighted  average common shares  outstanding and potential  common
shares  during the period.  Potential  common  shares  include  dilutive  shares
issuable upon the exercise of outstanding  common stock options,  warrants,  and
contingent  issuances  of common  stock.  For  periods in which the  Company has
losses (all periods  presented),  such potential common shares are excluded from
the computation of diluted net loss per share, as their effect is antidilutive.

Potentially dilutive securities include (in thousands):

Segment Reporting--For the year ended December 31, 1998, the Company adopted the
provisions of SFAS No. 131,  "Disclosures  about  Segments of an Enterprise  and
Related  Information."  The Company  operates  two  segments.  The  Analytic and
Diagnostic  segment  represents the operations of Glyko,  Inc. which involve the
manufacture  and sale of analytic and diagnostic  products.  The  Pharmaceutical
segment  represents  the  research  and  development  activities  related to the
development  and   commercialization   of  carbohydrate   enzyme   therapeutics.
Management of the Company has concluded  that the operations of the Analytic and
Diagnostic  segment are, and will continue to be, immaterial with respect to the
Company's overall activities and, thus, disclosure of segment information is not
required.

New  Accounting   Standards--In  June  1998,  the  FASB  issued  SFAS  No.  133,
"Accounting for Derivative  Instruments and Hedging Activities." SFAS No. 133 is
not expected to have a material impact on the Company's  consolidated  financial
position or results of operations.

In December 1999, the Securities and Exchange Commission issued Staff Accounting
Bulletin No. 101 ("SAB 101"), "Revenue Recognition in Financial Statements." SAB
101 provides guidance on applying  generally accepted  accounting  principles to
revenue recognition issues in financial statements.  The Company adopted SAB 101
as  required  in the  first  quarter  of 2000  and such  adoption  has not had a
material effect on the Company's  consolidated  financial position or results of
operations.

3.   STOCKHOLDERS' EQUITY:

Common  Stock and  Warrants  - As  disclosed  in the  accompanying  consolidated
statements of changes in  stockholders'  equity,  the Company closed a number of
private  placements in 1997 and 1998. In connection  with these  placements,  an
entity with which the former chief  executive  officer and chairman of the board
is affiliated  (see Note 7) was issued a total of 899,500 shares (valued at $1.4
million) and warrants (valued at $0.1 million) to purchase an additional 801,500
shares of common  stock at an exercise  price of $1 per share.  These  issuances
were made for brokerage  services  rendered in connection with these  placements
and were accounted for as a cost of raising capital. The warrants were exercised
in October 2000.






                                       44

Notes Receivable from Stockholders--Notes receivable from stockholders relate to
2.5 million  shares of common stock  issued in October  1997 to three  executive
officers  under  the  terms  of the  Founder's  Stock  Purchase  Agreement  (the
Agreement).  These notes bear  interest  at 6 percent per annum,  and are due on
March 31,  2001,  or on the date of the  employee's  termination,  whichever  is
earlier.  The  notes  are  secured  by the  underlying  stock  and are with full
recourse.  Interest  was  imputed  at nine  percent,  resulting  in an  interest
discount and related deferred compensation of $200,000, which is being amortized
over the life of the notes. In the event that their  employment is terminated by
the Company,  the Company has the  obligation,  if requested by the officer,  to
repurchase  any or all of the shares  issued under the Agreement at the lower of
the original  purchase price or the current  market value of the shares.  In the
event one of these officers ceases to be an employee, the Company has the right,
but not the  obligation,  to  repurchase  the unvested  portion of the shares at
their original  purchase price.  Pursuant to the terms of the Agreement,  50% of
the shares vest after one year from the date of  employment,  with the remainder
vesting at a rate of 1/24th per month  thereafter.  Upon the former  President's
resignation from the Company in July 2000, the Company repurchased 33,334 shares
at his original  purchase price and concurrently  reduced his promissory note to
the Company for the same amount.  In August 2000, the former  President paid the
balance of his  promissory  note plus accrued  interest to the  Company.  During
October 2000 the Company's  Chief  Executive  Officer  resigned.  His promissory
note, plus accrued interest, is due in full on March 31, 2001.

Deferred Compensation--In  connection with certain stock option and stock grants
during the years ended December 31, 1998,  1999 and 2000,  the Company  recorded
deferred  compensation  totaling  $3.2  million,  $0.7 million and $0.3 million,
respectively, which is being amortized over the estimated service periods of the
grantees.  Amortization  expense  recognized during the years ended December 31,
1998,  1999  and  2000,  was  $0.2  million,  $1.3  million  and  $1.4  million,
respectively.

4.   INCOME TAXES:

The Company  utilizes the asset and liability  method of  accounting  for income
taxes. Under the asset and liability method, deferred taxes are determined based
on the  difference  between the financial  statement and tax bases of assets and
liabilities  using  enacted  tax  rates in  effect  in the  years  in which  the
differences are expected to reverse.

The  Company's  primary  temporary  differences  relate  to items  expensed  for
financial  reporting  purposes  but not  currently  deductible  for  income  tax
purposes, consisting primarily of depreciable lives for property and equipment.

As of December 31, 2000,  net operating  loss  carryforwards  are  approximately
$74.9 million and $66.1 million for federal and California  income tax purposes,
respectively.  These net operating loss  carryforwards,  including net operating
losses of $12.6  million and $2.9 million for federal and  California  purposes,
respectively,  related to Glyko,  Inc.  These  federal  and state  carryforwards
expire beginning in the year 2011 and 2004, respectively.

The Company also has research and development credits available to reduce future
federal and California  income taxes, if any, of approximately  $2.8 million and
$2.8 million,  respectively, at December 31, 2000. These credits include credits
related to Glyko,  Inc.  of  approximately  $0.6  million  and $0.3  million for
federal  and  California  purposes,   respectively.   These  federal  and  state
carryforwards expire beginning in 2012 and 2013, respectively.

The Company also has orphan drug  credits  available  to reduce  future  federal
income taxes, if any, of approximately $7.3 million at December 31, 2000.

The net  operating  loss  carryforwards  and  research and  development  credits
related to Glyko,  Inc.  as of October 7, 1998,  can only be  utilized to offset
future taxable income and tax, respectively, if any, of Glyko, Inc. In addition,
the Tax Reform Act of 1986 contains  provisions that may limit the net operating
loss carryforwards and research and development  credits available to be used in
any given year should certain events occur,  including sale of equity securities
and other changes in ownership.  The acquisition of Glyko,  Inc. and the related
issuance of stock  represented  a change of  ownership  under these  provisions.
There can be no assurance that the Company will be able to utilize net operating
loss carryforwards and credits before expiration.

Deferred  income  taxes are recorded to reflect the tax  consequences  on future
years of differences  between the tax basis of assets and  liabilities and their
financial reporting amounts at each period-end. The Company has a cumulative net
operating  loss  carryforward  since  inception,  resulting  in net deferred tax
assets. A valuation allowance is placed on the net deferred tax assets to reduce
them to an assumed net realizable value of zero.

5.   STOCK OPTION PLANS:

1997 Stock Plan--In  November  1997,  the Board adopted,  and in April 1998, the
stockholders  approved,  the 1997 Stock Plan (the 1997 Plan), which provided for
the  reservation  of a total of  3,000,000  shares of common  stock for issuance
under the 1997 Plan. In December 1998,  the Board adopted,  and in January 1999,
the stockholders  approved, an amendment to the 1997 Plan to increase the number




                                       45

of shares reserved for issuance under it to an aggregate of 5,000,000 and to add
an  "evergreen  provision"  providing  for an annual  increase  in the number of
shares  which may be  optioned  or sold  under the 1997  Plan  without  need for
additional Board or stockholder  action to approve such increase (which increase
shall  be the  lesser  of 4  percent  of  the  then-outstanding  capital  stock,
2,000,000  shares, or a lower amount set by the Board). As of December 31, 2000,
the number of shares  reserved for issuance was an aggregate of 7,695,572  under
the 1997 Plan.  The 1997 Plan  provides  for the grant of stock  options and the
issuance of common stock by the Company to its employees,  officers,  directors,
and consultants.

1998 Director Option Plan--The 1998 Director Option Plan (the Director Plan) was
adopted  by the Board in  December  1998 and  approved  by the  stockholders  in
January 1999.  The Director Plan  provides for the grant of  nonstatutory  stock
options to  non-employee  directors.  A total of 200,000 shares of the Company's
common stock,  plus an annual  increase  equal to the number of shares needed to
restore  the maximum  aggregate  number of shares  available  for sale under the
Director  Plan or the lesser of 0.5 percent of the  outstanding  capital  stock,
200,000  shares,  or a lesser  amount set by the Board,  have been  reserved for
issuance under the Director  Plan. As of December 31, 2000,  options to purchase
165,000  shares were  granted  under the  Director  Plan and options to purchase
400,000 shares were authorized under the Director Plan.

 Options  currently  outstanding  under the Company's 1997 Stock Option Plan and
1998 Director Plan (the Plans)  generally  have vesting  schedules of up to four
years and options terminate after five to ten years or 90 days after termination
of employment or contract.

The  Company  accounts  for  option  grants  in  accordance  with  APB  25.  Had
compensation cost for option grants to employees under the Plans been determined
consistent  with the fair value  provisions  of SFAS No. 123,  the effect on the

(BioMarin/Genzyme  LLC) for the worldwide  development and  commercialization of
Aldurazyme  to treat  MPS-I.  In  conjunction  with the  formation  of the joint
venture,  the Company established a wholly-owned subsidiary,  BioMarin Genetics,
Inc.  The  Company  has a 49 percent  interest  in the joint  venture,  BioMarin
Genetics,  Inc.  has a 1 percent  interest,  and  Genzyme has the  remaining  50
percent interest.

Under the Collaboration  Agreement, the Company and Genzyme are each required to
make capital contributions to the joint venture in an amount equal to 50 percent
of costs and expenses associated with the development and  commercialization  of
Aldurazyme.  The  parties  also  agree to share the  profits  equally  from such
commercialization.  In  addition,  Genzyme  purchased  1,333,333  shares  of the
Company's  common stock at $6 per share in a private  placement  for proceeds of
$8.0 million and,  concurrent  with the IPO,  purchased  an  additional  769,230
shares of the Company's  common stock at the IPO price for an  additional  $10.0
million.  Genzyme has also agreed to pay the Company  $12.1 million in cash upon
FDA approval of the biologics license application for Aldurazyme.

Other   Agreements--The   Company  is  engaged  in  research   and   development
collaborations with various academic  institutions,  commercial research groups,
and other  entities.  The  agreements  provide for  sponsorship  of research and
development  by the Company and may also provide for  exclusive  royalty-bearing
intellectual property licenses or rights of first negotiation regarding licenses
to intellectual property development under the collaborations.  Typically, these
agreements are terminable for cause by either party upon 90 days written notice.

9.   COMPENSATION PLANS:

Employment  Agreements--The  Company has entered into employment agreements with
eight officers of the Company.  Seven of these agreements are terminable without
cause by the Company upon six months prior notice,  or by the officer upon three
months prior written  notice to the Company,  with the Company  obligated to pay
salary  and  benefits  hereunder  until  such  termination.  In  the  employment
agreement  with the Company's  Chief  Executive  Officer the agreement  shall be
renewed  after three years for one  additional  three-year  period unless either
party gives nine months notice prior to the expiration of the initial three-year
period.   The  annual  salaries   committed  to  under  these  agreements  total
approximately $2 million.  In addition,  three of the agreements provide for the
payment of an annual cash bonus of up to 100  percent of the base annual  salary
of the three officers  based upon the Company's  market  capitalization  through
June 30, 2000. Bonuses for the three officers totaled $294,000 in 2000.

401(k) Plan--The Company  participates in the BioMarin  Retirement Savings Plan.
Most employees (Participants) are eligible to participate following the start of
their employment,  on the earlier of the next occurring January 1, April 1, July
1 or October 1.  Participants  may  contribute up to 15 percent of their current
compensation  to the  401(k)  Plan or an amount up to a  statutorily  prescribed
annual  limit.  The  Company  pays the direct  expenses  of the 401(k)  Plan and
matches 25% of the first 2% contributed to the employee accounts.  The Company's
matching contribution vests over four years from employment commencement.

1998 Employee Stock Purchase  Plan--In  December 1998 the Board adopted,  and in

11.   CARSON STREET CLOSURE

During the first quarter of 2000, the Company decided to close its Carson Street
clinical  manufacturing  facility. In connection with this decision, the Company
recorded a charge of  approximately  $4.4  million.  The  facility was no longer
required for the  production of  Aldurazyme,  the initial  purpose of the plant,
after a decision by the  BioMarin/Genzyme LLC joint venture to use the Company's
Galli Drive facility for the  manufacture of bulk  Aldurazyme both for the Phase
III trial and for the commercial  launch of Aldurazyme.  This decision was based
in part  on U.S.  Food  and  Drug  Administration  guidance  to use an  improved
production  process,  which was installed in the Galli Drive  facility,  for the
clinical trial, the biologics license application  submission and for commercial
production.  The majority of the Company's  technical staff at the Carson Street
facility in  Torrance,  California  transferred  to the Galli Drive  facility in
Novato, California in May. The charge primarily consisted of impairment reserves
for leasehold improvements and equipment located in the Carson Street facility.

12.   SUBSEQUENT EVENT

In January 2001,  the Company signed an agreement  with Acqua  Wellington  North

share.

13.  QUARTERLY CONSOLIDATED FINANCIAL DATA (unaudited)

22, 1999.  There were 64 common  stockholders of record at December 31, 2000. No

                             Dated October 9, 2001


                  This Assumption Agreement (this "Agreement") is made pursuant
to that certain Canadian Asset Purchase Agreement (the "Purchase Agreement")
dated as of October 9, 2001, by and among BIOMARIN PHARMACEUTICAL INC., a
Delaware corporation ("BioMarin"), BIOMARIN PHARMACEUTICAL NOVA SCOTIA COMPANY,

         In consideration of the sale, pursuant to the Purchase Agreement, by

Ladies and Gentlemen:

We have acted as special counsel to BioMarin Pharmaceutical Inc., a Delaware
corporation ("Biomarin") and BioMarin Enzymes Inc., a Delaware corporation
("BioMarin Sub" and, together with BioMarin, the "BioMarin U.S. Group"), in
connection with that certain United States Purchase Agreement ("U.S. Agreement")
dated as of October 9, 2001, by and among BioMarin and BioMarin Sub, on the one
hand, and IBEX Technologies Inc., a Canadian corporation ("IBEX"), IBEX
Pharmaceuticals Inc., a Canadian corporation ("IBEX Pharma"), IBEX Technologies
LLC, a Delaware limited liability company ("IBEX LLC"), IBEX Technologies Corp.,
a Delaware corporation ("IBEX Corp.") and Technologies IBEX R & D Inc., a
corporation incorporated pursuant to the laws of the Province of Quebec ("IBEX R
& D," together with IBEX, IBEX Pharma, IBEX LLC and IBEX Corp., the "IBEX
Group") on the other hand, and in connection with that certain Canadian Purchase
Agreement ("Canadian Agreement" and, together with the U.S. Agreement, the
"Purchase Agreements") dated as of October 9, 2001 by and among BioMarin and
BioMarin Pharmaceutical Nova Scotia Company, a corporation incorporated pursuant
to the laws of the Province of Nova Scotia ("BioMarin NS"), on the one hand, and
the members of the IBEX Group, on the other hand. The members of the BioMarin
U.S. Group, BioMarin NS, and the members of the IBEX Group shall be referred to
herein collectively from time to time as the "Parties." We have been asked to
provide this opinion letter in accordance with the requirements set forth in
Section 11.1(e) of the U.S. Agreement and Section 11.1(f) of the Canadian
Agreement. Capitalized terms used but not defined in this letter shall have the
meanings ascribed to such terms in the applicable Purchase Agreement.




October 31, 2001

In connection with the foregoing, we have examined (i) the U.S. Agreement, (ii)
the Canadian Agreement, (iii) a License Agreement dated as of October 31, 2001,
among the members of the BioMarin U.S. Group and BioMarin NS, IBEX and IBEX
Pharma (the "License Agreement"), (iv) a Services, Equipment and Space Sharing
Agreement dated as of October 31, 2001, among the members of the IBEX Group,
BioMarin and BioMarin NS (the "Services Agreement"), (v) the certificate of
incorporation of each of BioMarin and BioMarin Sub, as amended through the date
hereof, (vi) the bylaws of each of BioMarin and BioMarin Sub, each of which has
been certified to us by an officer of each of BioMarin and BioMarin Sub, (vii)
certificates of officers of each of BioMarin and BioMarin Sub, (viii)
certificates of public officials as we have deemed necessary or advisable, and
(ix) such other documents, records, certificates and instruments as we have
deemed necessary or advisable in order to render the opinions expressed herein.

In such examination and in rendering our opinion, we have assumed the
authenticity of all original documents and company records submitted to us, the
genuineness of all signatures, the legal capacity of all natural persons, the
conformity to original, executed documents of all copies and photocopies
submitted to us, the due authorization, execution and delivery of all documents
where due authorization, execution and delivery are a prerequisite to the
effectiveness thereof (other than the Documents, as defined below), that there
are no agreements or understandings among the Parties, written or oral and there
is no usage of trade or course of prior dealing among the Parties that would, in
either case, define, supplement, or qualify the terms of any of the U.S.
Agreement, the Canadian Agreement, the License Agreement or the Services
Agreement (collectively, the "Documents"), and that all parties will act in
accordance with and will refrain from taking any action that is forbidden by the
Documents. As to various questions of fact material to this opinion, without
investigation, we have relied upon statements or certificates of officers or
authorized persons of each member of the BioMarin U.S. Group and of public
officials and others, as well as the accuracy of representations and warranties
made by the members of the BioMarin U.S. Group in the Documents, and we assume
compliance on the part of all the Parties with their covenants and agreements
contained therein. We have also assumed that the offer, issuance or sale of
securities under the Purchase Agreements will not be integrated for purposes of
Rule 4350 of the Nasdaq listing requirements with the offer, issuance or sale of
any securities to any investor consummated within the six months preceding the
date hereof.

In expressing the opinion set forth in paragraph 1 below, we have relied
exclusively on the good standing certificates of each of the members of the
BioMarin U.S. Group.

In rendering our opinions set forth in paragraph 7 below, we have not made any
independent investigation of court records to determine whether any action,
suit, arbitration, claim or proceeding has been filed and our opinions are based
solely upon a written certificate provided to us by the Secretary of the
Company.

As used in this letter, the expression "to our knowledge" or "of which we have
knowledge" or phrases of like import with reference to matters of fact means
that, after an examination of documents made available to us by members of the
BioMarin U.S. Group and after inquiries of officers or authorized persons of the
BioMarin U.S. Group, we have no reason to believe that the opinions expressed
herein are factually incorrect; but beyond that we have made no independent
factual investigation for the purpose of rendering this opinion. Moreover,
"knowledge" of this Firm is limited to the individual attorneys in the Firm who
have represented the BioMarin U.S. Group in connection with the Documents.
Except to the extent expressly set forth herein or as we otherwise believe to be
necessary to our opinion, we have not undertaken any independent investigation
to determine the existence or absence of any fact, and no inference as to our
knowledge of the existence or absence of any fact should be drawn from our
representation of the BioMarin U.S. Group or the rendering of the opinions set
forth below.

On the basis of the foregoing examinations and assumptions contained herein and
in reliance thereon, and on all matters of fact that we deem relevant under the
circumstances, and upon consideration of applicable law, subject to the
qualifications herein stated, we are of the opinion that:

              1.   Each of BioMarin and BioMarin Sub has been duly formed and is
validly existing as a corporation in good standing under the laws of the State
of Delaware.

              2.   Each of BioMarin and BioMarin Sub has all requisite corporate
power and authority to enter into the Canadian Agreement and the Services
Agreement, in the case of BioMarin, and the U.S. Agreement and the License
Agreement, the in the case of BioMarin and BioMarin Sub, and to consummate the
transactions contemplated thereby.

              3.   Each of BioMarin and BioMarin Sub has duly executed each of
the Documents to which it is a party, and each of BioMarin and BioMarin Sub has
taken all necessary corporate action to authorize and approve the execution,
delivery and performance on its part of the Documents executed by it and the
consummation of the transactions contemplated thereby.

              4.   Each of the Documents constitutes the valid and binding
obligation of BioMarin, enforceable against BioMarin in accordance with its
terms, except as such enforceability may be subject to the effect of (i) any
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer, fraudulent conveyance or other law relating to or affecting the
enforcement of creditors' rights generally and (ii) general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law). The U.S. Agreement and the License Agreement constitutes the
valid and binding obligation of BioMarin Sub, enforceable against BioMarin Sub



October 31, 2001
Page 4

in accordance with its terms, except as such enforceability may be subject to
the effect of (i) any applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer, fraudulent conveyance or other law relating to
or affecting the enforcement of creditors' rights generally and (ii) general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

              5.   The BioMarin Canadian Transaction Shares and the BioMarin
Worldwide Shares are duly authorized and, when issued in accordance with the
Purchase Agreements, will be validly issued, fully paid and nonassessable, free
and clear of all liens and restrictions, other than those imposed by Section 7.3
of the U.S. Agreement and Section 7.3 of the Canadian Agreement, the Securities
Act and other applicable securities laws or those created or suffered by any
member of the IBEX Group.

              6.   The shares of common stock of BioMarin issuable upon exercise
of the BioMarin Options are duly authorized and, when issued in accordance with
the terms of the Certificate and the BioMarin Options, respectively, will be
validly issued, fully paid and nonassessable and free and clear of all liens and
restrictions, other than those created or suffered by any member of the IBEX
Group or those imposed by the Securities Act or other applicable securities laws
or either Purchase Agreement.

              7.   To our knowledge, and without having performed any due
diligence review with respect to either BioMarin or BioMarin Sub, there is no
legal action, suit, arbitration or other legal proceeding pending against any
member of the BioMarin U.S. Group before any court. To our knowledge, neither
BioMarin nor BioMarin Sub is in default with respect to any order, writ,
judgment, injunction, decree, determination or award of any court or of any
government agency or instrumentality listed on Attachment No. 1 hereto.

The opinions set forth above are subject to the following limitations and
qualifications:

                   A.   Our opinions in paragraphs 1, 2 and 3 are limited to the
Delaware General Corporate Law as it exists on the date hereof. With respect to
our opinions in paragraphs 4, 5, 6, and 7 of our opinions are limited in all
respects to the laws of the State of California and the United States of America
as they exist on the date hereof. Except as set forth in this clause, we do not
opine as to the applicability or effect of the laws of any other jurisdiction
including, without limitation, Canadian law or the laws of Quebec or of any
other Province of Canada, or any other laws of the State of Delaware. Our
opinion on California law does not extend to municipal ordinances or laws of
counties or other political subdivisions of such State.



October 31, 2001

                   B.   We call your attention to the fact that each of the U.S.
Agreement and the License Agreement states that it is governed by Delaware law
and each of the Canadian Agreement and the Services Agreement states that it is
governed by the laws of the Province of Quebec, and we are not rendering any
opinion with respect to the laws of the Province of Quebec or the laws of the
State of Delaware, except as expressly described in clause A above with respect
to Delaware General Corporate Law. We have not examined the question of what law
would govern the interpretation, validity or enforcement of the Documents and we
express no opinion thereon. In addition, we express no opinion as to whether
California law would govern the interpretation, validity or enforcement of the
Documents, and we have no reason to believe that California law would govern
such matters.

                   C.   We express no opinion as to any federal or state
securities, antitrust or unfair competition laws or regulations nor as to the
effect of non-compliance by any member of the IBEX Group with any state or
federal laws or regulations that are applicable to the transactions contemplated
by the Documents because of the nature of its businesses or the manner in which
they are conducted.

                   D.   We express no opinion as to the enforceability of any
covenant in any Document obligating BioMarin or BioMarin Sub to indemnify any
person or entity, or having the same or substantially the same effect as
indemnification.

                   E.   We express no opinion as to the enforceability of any
provision in any Document regarding a party's ability or right to collect
attorneys' fees and costs in an action involving such Document.

                   F.   We express no opinion as to any non-competition clause
or covenant in any document or agreement to be delivered under the terms of
either Purchase Agreement.

                   G.   Except as provided herein, we express no opinion with
respect to the enforceability of any agreement, contract or instrument referred
to, identified in or attached (whether as an exhibit, annex, schedule or
otherwise) to any of the Documents.

                   H.   We have assumed there is no misrepresentation, omission
or deceit by any person in connection with the execution, delivery or
performance of the Documents or any of the transactions contemplated thereby.

                   I.   We express no opinion as to the effect of any provision
of any Document which relates to waiving defenses or releasing or indemnifying a



October 31, 2001
Page 6

party against liability for its own wrongful or negligent acts, or where waivers
or indemnifications are limited by applicable law or public policy.

                   J.   We express no opinion with respect to the enforceability
of any provision in any Document to the effect that terms may not be waived or
modified except in writing and advise you that such provisions may be limited
under certain circumstances.

                   K.   We express no opinion as to the validity, effect or
enforceability of any provision of any Document concerning choice of law, choice
of forum or consent to the jurisdiction of courts, venue of actions or means of
service of process.

This opinion letter deals only with the specified legal issues it explicitly
addresses, and no opinion that is not explicitly addressed should be inferred
from any matter stated in this letter.

This opinion is furnished to you by us as special counsel for BioMarin and
BioMarin Sub in connection with the matters described in the first paragraph of
this letter, and is solely for your benefit. This opinion may not be delivered
to or relied upon by any other person or for any other purpose, and may not be
referred to or quoted from, without our express prior written consent. This
opinion is rendered to you as of the date hereof, and we assume no obligation to
update you with respect to the matters set forth herein.

Very truly yours,

BioMarin Pharmaceutical Nova Scotia Company, a corporation incorporated pursuant
to the laws of the Province of Nova Scotia ("BioMarin NS"), on the one hand, and
the members of the IBEX Group, on the other hand. The members of the BioMarin
U.S. Group, BioMarin NS, and the members of the IBEX Group shall be referred to

provide this opinion letter in accordance with the requirements set forth in

In connection with the foregoing, we have examined (i) the U.S. Agreement, (ii)
the Canadian Agreement, (iii) a License Agreement dated as of October 31, 2001,
among the members of the BioMarin U.S. Group and BioMarin NS, IBEX and IBEX
Pharma (the "License Agreement"), (iv) a Services, Equipment and Space Sharing
Agreement dated as of October 31, 2001, among the members of the IBEX Group,
BioMarin and BioMarin NS (the "Services Agreement"), (v) the certificate of
incorporation of each of BioMarin and BioMarin Sub, as amended through the date
hereof, (vi) the bylaws of each of BioMarin and BioMarin Sub, each of which has
been certified to us by an officer of each of BioMarin and BioMarin Sub, (vii)
certificates of officers of each of BioMarin and BioMarin Sub, (viii)
certificates of public officials as we have deemed necessary or advisable, and
(ix) such other documents, records, certificates and instruments as we have
deemed necessary or advisable in order to render the opinions expressed herein.

In such examination and in rendering our opinion, we have assumed the
authenticity of all original documents and company records submitted to us, the
genuineness of all signatures, the legal capacity of all natural persons, the
conformity to original, executed documents of all copies and photocopies
submitted to us, the due authorization, execution and delivery of all documents
where due authorization, execution and delivery are a prerequisite to the
effectiveness thereof (other than the Documents, as defined below), that there
are no agreements or understandings among the Parties, written or oral and there
is no usage of trade or course of prior dealing among the Parties that would, in
either case, define, supplement, or qualify the terms of any of the U.S.
Agreement, the Canadian Agreement, the License Agreement or the Services
Agreement (collectively, the "Documents"), and that all parties will act in
accordance with and will refrain from taking any action that is forbidden by the
Documents. As to various questions of fact material to this opinion, without
investigation, we have relied upon statements or certificates of officers or
authorized persons of each member of the BioMarin U.S. Group and of public
officials and others, as well as the accuracy of representations and warranties
made by the members of the BioMarin U.S. Group in the Documents, and we assume
compliance on the part of all the Parties with their covenants and agreements
contained therein. We have also assumed that the offer, issuance or sale of
securities under the Purchase Agreements will not be integrated for purposes of
Rule 4350 of the Nasdaq listing requirements with the offer, issuance or sale of
any securities to any investor consummated within the six months preceding the
date hereof.

In expressing the opinion set forth in paragraph 1 below, we have relied
exclusively on the good standing certificates of each of the members of the
BioMarin U.S. Group.

In rendering our opinions set forth in paragraph 7 below, we have not made any
independent investigation of court records to determine whether any action,
suit, arbitration, claim or proceeding has been filed and our opinions are based
solely upon a written certificate provided to us by the Secretary of the
Company.

As used in this letter, the expression "to our knowledge" or "of which we have
knowledge" or phrases of like import with reference to matters of fact means
that, after an examination of documents made available to us by members of the
BioMarin U.S. Group and after inquiries of officers or authorized persons of the
BioMarin U.S. Group, we have no reason to believe that the opinions expressed
herein are factually incorrect; but beyond that we have made no independent
factual investigation for the purpose of rendering this opinion. Moreover,
"knowledge" of this Firm is limited to the individual attorneys in the Firm who
have represented the BioMarin U.S. Group in connection with the Documents.
Except to the extent expressly set forth herein or as we otherwise believe to be
necessary to our opinion, we have not undertaken any independent investigation
to determine the existence or absence of any fact, and no inference as to our
knowledge of the existence or absence of any fact should be drawn from our
representation of the BioMarin U.S. Group or the rendering of the opinions set
forth below.

On the basis of the foregoing examinations and assumptions contained herein and
in reliance thereon, and on all matters of fact that we deem relevant under the
circumstances, and upon consideration of applicable law, subject to the
qualifications herein stated, we are of the opinion that:

              1.   Each of BioMarin and BioMarin Sub has been duly formed and is
validly existing as a corporation in good standing under the laws of the State
of Delaware.

              2.   Each of BioMarin and BioMarin Sub has all requisite corporate
power and authority to enter into the Canadian Agreement and the Services
Agreement, in the case of BioMarin, and the U.S. Agreement and the License
Agreement, the in the case of BioMarin and BioMarin Sub, and to consummate the
transactions contemplated thereby.

              3.   Each of BioMarin and BioMarin Sub has duly executed each of
the Documents to which it is a party, and each of BioMarin and BioMarin Sub has
taken all necessary corporate action to authorize and approve the execution,
delivery and performance on its part of the Documents executed by it and the
consummation of the transactions contemplated thereby.

              4.   Each of the Documents constitutes the valid and binding
obligation of BioMarin, enforceable against BioMarin in accordance with its
terms, except as such enforceability may be subject to the effect of (i) any
applicable bankruptcy, insolvency, reorganization, moratorium, fraudulent
transfer, fraudulent conveyance or other law relating to or affecting the
enforcement of creditors' rights generally and (ii) general principles of equity
(regardless of whether such enforceability is considered in a proceeding in
equity or at law). The U.S. Agreement and the License Agreement constitutes the
valid and binding obligation of BioMarin Sub, enforceable against BioMarin Sub



October 31, 2001
Page 4

in accordance with its terms, except as such enforceability may be subject to
the effect of (i) any applicable bankruptcy, insolvency, reorganization,
moratorium, fraudulent transfer, fraudulent conveyance or other law relating to
or affecting the enforcement of creditors' rights generally and (ii) general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law).

              5.   The BioMarin Canadian Transaction Shares and the BioMarin
Worldwide Shares are duly authorized and, when issued in accordance with the
Purchase Agreements, will be validly issued, fully paid and nonassessable, free
and clear of all liens and restrictions, other than those imposed by Section 7.3
of the U.S. Agreement and Section 7.3 of the Canadian Agreement, the Securities
Act and other applicable securities laws or those created or suffered by any
member of the IBEX Group.

              6.   The shares of common stock of BioMarin issuable upon exercise
of the BioMarin Options are duly authorized and, when issued in accordance with
the terms of the Certificate and the BioMarin Options, respectively, will be
validly issued, fully paid and nonassessable and free and clear of all liens and
restrictions, other than those created or suffered by any member of the IBEX
Group or those imposed by the Securities Act or other applicable securities laws
or either Purchase Agreement.

              7.   To our knowledge, and without having performed any due
diligence review with respect to either BioMarin or BioMarin Sub, there is no
legal action, suit, arbitration or other legal proceeding pending against any
member of the BioMarin U.S. Group before any court. To our knowledge, neither
BioMarin nor BioMarin Sub is in default with respect to any order, writ,
judgment, injunction, decree, determination or award of any court or of any
government agency or instrumentality listed on Attachment No. 1 hereto.

The opinions set forth above are subject to the following limitations and
qualifications:

                   A.   Our opinions in paragraphs 1, 2 and 3 are limited to the
Delaware General Corporate Law as it exists on the date hereof. With respect to
our opinions in paragraphs 4, 5, 6, and 7 of our opinions are limited in all
respects to the laws of the State of California and the United States of America
as they exist on the date hereof. Except as set forth in this clause, we do not
opine as to the applicability or effect of the laws of any other jurisdiction
including, without limitation, Canadian law or the laws of Quebec or of any
other Province of Canada, or any other laws of the State of Delaware. Our
opinion on California law does not extend to municipal ordinances or laws of
counties or other political subdivisions of such State.



October 31, 2001

                   B.   We call your attention to the fact that each of the U.S.
Agreement and the License Agreement states that it is governed by Delaware law
and each of the Canadian Agreement and the Services Agreement states that it is
governed by the laws of the Province of Quebec, and we are not rendering any
opinion with respect to the laws of the Province of Quebec or the laws of the
State of Delaware, except as expressly described in clause A above with respect
to Delaware General Corporate Law. We have not examined the question of what law
would govern the interpretation, validity or enforcement of the Documents and we
express no opinion thereon. In addition, we express no opinion as to whether
California law would govern the interpretation, validity or enforcement of the
Documents, and we have no reason to believe that California law would govern
such matters.

                   C.   We express no opinion as to any federal or state
securities, antitrust or unfair competition laws or regulations nor as to the
effect of non-compliance by any member of the IBEX Group with any state or
federal laws or regulations that are applicable to the transactions contemplated
by the Documents because of the nature of its businesses or the manner in which
they are conducted.

                   D.   We express no opinion as to the enforceability of any
covenant in any Document obligating BioMarin or BioMarin Sub to indemnify any
person or entity, or having the same or substantially the same effect as
indemnification.

                   E.   We express no opinion as to the enforceability of any
provision in any Document regarding a party's ability or right to collect
attorneys' fees and costs in an action involving such Document.

                   F.   We express no opinion as to any non-competition clause
or covenant in any document or agreement to be delivered under the terms of
either Purchase Agreement.

                   G.   Except as provided herein, we express no opinion with
respect to the enforceability of any agreement, contract or instrument referred
to, identified in or attached (whether as an exhibit, annex, schedule or
otherwise) to any of the Documents.

                   H.   We have assumed there is no misrepresentation, omission
or deceit by any person in connection with the execution, delivery or
performance of the Documents or any of the transactions contemplated thereby.

                   I.   We express no opinion as to the effect of any provision
of any Document which relates to waiving defenses or releasing or indemnifying a



October 31, 2001
Page 6

party against liability for its own wrongful or negligent acts, or where waivers
or indemnifications are limited by applicable law or public policy.

                   J.   We express no opinion with respect to the enforceability
of any provision in any Document to the effect that terms may not be waived or
modified except in writing and advise you that such provisions may be limited
under certain circumstances.

                   K.   We express no opinion as to the validity, effect or
enforceability of any provision of any Document concerning choice of law, choice
of forum or consent to the jurisdiction of courts, venue of actions or means of
service of process.

This opinion letter deals only with the specified legal issues it explicitly
addresses, and no opinion that is not explicitly addressed should be inferred
from any matter stated in this letter.

This opinion is furnished to you by us as special counsel for BioMarin and
BioMarin Sub in connection with the matters described in the first paragraph of
this letter, and is solely for your benefit. This opinion may not be delivered
to or relied upon by any other person or for any other purpose, and may not be
referred to or quoted from, without our express prior written consent. This
opinion is rendered to you as of the date hereof, and we assume no obligation to
update you with respect to the matters set forth herein.

Very truly yours,

Dear Sirs:

We have acted as counsel to BioMarin Pharmaceutical Nova Scotia Company
("BioMarin NS") and BioMarin Pharmaceuticals Inc. ("BioMarin") in connection
with the preparation, execution and delivery of a Canadian Asset Purchase
Agreement dated as of o, 2001 (the "Canadian Agreement"), by and among BioMarin
NS and BioMarin (collectively, the "BioMarin Group") and IBEX Technologies Inc.
("IBEX"), IBEX Pharmaceuticals Inc. ("IBEX Pharma"), Technologies IBEX R&D Inc.
("IBEX R&D"), IBEX Technologies LLC ("IBEX LLC") and IBEX Technologies Corp
("IBEX Corp") (collectively, the "IBEX Group").

This opinion is delivered to you pursuant to the Canadian Agreement. Capitalized
terms used herein and not defined herein shall have the meanings ascribed
thereto in the Canadian Agreement.

In connection with this opinion, we have examined originals or copies certified
or authenticated to our satisfaction, of the following:

(a)     the Canadian Agreement;

(b)     a services, equipment and space sharing agreement dated o, 2001 among
        the members of the IBEX Group and the members of the BioMarin Group (the
        "Services Agreement"); and

(c)     a certificate of a senior officer of each member of the BioMarin Group
        and BioMarin US dated as of the date hereof, a copy of which is attached
        hereto (the "Officer's Certificate").



                                                                          Page 2


We have examined originals or copies, certified or identified to our
satisfaction, of the constating documents and by-laws of each of the members of
the BioMarin Group and of such corporate records of each of the members of the
BioMarin Group, certificates of public officials, officers of each of the
members of the BioMarin Group and such other documents and have considered such
questions of law and have made such other investigations as we have deemed
relevant or necessary as a basis for the opinions hereinafter expressed.

For the purposes hereof, we have assumed, with your permission and without
independent verification of any kind: (a) that the signatures of Persons signing
all documents in connection with which this opinion is rendered are genuine and
authorized; (b) the legal capacity of all natural persons; (c) that all
documents submitted to us as originals or duplicate originals are authentic; (d)
that all documents submitted to us as copies, whether certified or not, conform
to authentic original documents; (e) there has not been any mutual mistake of
fact or misunderstanding, error, fear, lesion, fraud, duress, or undue
influence; (f) there are no agreements or understandings among the Parties,
written or oral and there is no usage of trade or course of prior dealing among
the Parties that would, in either case, define, supplement, or qualify the terms
of the Canadian Agreement, and/or the Services Agreement (collectively, the
"Documents"); (g) the contracts, agreements or instruments to which each of the
members of the BioMarin Group is a party or by which their properties are bound,
specifically excluding the Documents and the U.S. Purchase Agreement, will be
enforced as written; (h) all Parties will act in accordance with, and will
refrain from taking any action that is forbidden by, the Documents; (i) all
Parties will act in accordance with the terms and conditions of the Documents;
(j) each member of the BioMarin Group and BioMarin US and each member of the
IBEX Group has been duly incorporated and is validly existing and in good
standing under the laws of its respective jurisdiction of incorporation and each
other jurisdiction in which the conduct of its respective business or the
ownership of its respective properties makes such qualification necessary; (k)
the Documents have been duly executed and delivered by each member of the
BioMarin Group and each member of the IBEX Group; and (l) each of the Documents
constitute a valid and legally binding obligation of each member of the IBEX
Group who has signed each of the Documents.

As to questions of fact relevant to this opinion, we have assumed the accuracy
of the representations and warranties of the members of the BioMarin Group in
the Documents to which they are a party and we assume compliance on the part of
all Parties with their covenants and agreements contained therein.

We are qualified to carry on the practice of law in the Province of Quebec only
and we express no opinion as to any laws or matters governed by any laws, other
than the laws of the Province of Quebec and the federal laws of Canada
applicable therein. The opinions herein are limited to the laws of the Province
of Quebec and the federal laws of Canada applicable herein in effect as of the
date hereof and we assume no obligation to update these opinions to take into
account any changes in such laws after the date hereof.

The phrase "to our knowledge" when used in this opinion is intended to indicate
that, during the course of our representation of the members of the BioMarin
Group, no information that would give us actual knowledge (as at the date
hereof) of the inaccuracy of such opinions has come to the attention of the
lawyers advising the members of the BioMarin Group.

Based upon and subject to the foregoing and the qualifications set forth below,
we are of the opinion that:

1.       The execution, delivery and performance by each member of the BioMarin
         Group of each of the Documents and the consummation of the Transaction,
         subject to the Bulk Sales Carve-out, will not contravene any laws of
         the Province of Quebec.

2.       Save and except as provided in the Documents, no authorization, consent
         or approval of, or filing with or notice to; (i) any governmental



                                                                          Page 3


         agency or regulatory body; or (ii) to our knowledge, any court or other
         Person; is required to be obtained by any member of the BioMarin Group
         in connection with the execution, delivery or performance of any of the
         the Documents by each member of the BioMarin Group.

3.       Each of the Documents is a legal, valid and binding obligation of each
         member of the BioMarin Group, enforceable against each member of the
         BioMarin Group in accordance with its respective terms.

The opinion set forth in section 3 above is subject to the qualifications that:

         (i)      Enforceability may be limited by bankruptcy, insolvency,
                  reorganization, receivership, moratorium, arrangement or
                  winding-up laws or other similar laws affecting the
                  enforcement of creditors' rights generally.

         (ii)     Enforceability may be limited by equitable principles,
                  including the principle that equitable remedies such as
                  specific performance and injunction may only be granted in the
                  discretion of a court of competent jurisdiction and may not be
                  awarded where damages are considered an adequate remedy.

         (iii)    A provision purporting to allow severance of a provision or
                  restricting its effect may not be enforceable if such
                  severance or restriction would not accord with public policy
                  or would involve a court in making a new contract for the
                  parties.

         (iv)     We express no opinion as to the validity of any provision in
                  the Documents that purports to establish any evidentiary
                  standard or purports to give or affect any right to notice.

         (v)      We express no opinion as to any non-competition clause or
                  covenant in any document or agreement to be delivered under
                  the terms of the Documents.


This opinion is rendered solely for your benefit in connection with the
Transaction and is not to be relied upon by any other Person or otherwise
furnished to third parties, used, circulated, quoted or relied upon, without our
prior consent. This opinion is as of the date hereof, and we undertake no, and
hereby disclaim any, obligation to advise you of any change in any matters set
forth herein.

Yours very truly,

agreement to which IBEX is a party or by which it is bound; and
              (d)   the execution and delivery of this Agreement and the

              6.03  Nothing in this Agreement shall be read or construed as:
              (a)   a warranty or representation as to the commercial utility of
the Licensed Products or any product based on the Assigned Patent Rights;
              (b)   a warranty or representation that any pending application

            ARTICLE VIII - PATENT ENFORCEMENT AND THIRD PARTY PATENTS
            ---------------------------------------------------------

              8.01  BioMarin intends, but shall not be obligated, to protect its
interests in any Assigned Patent Rights from infringement by third parties and
to prosecute infringers or otherwise act to eliminate infringement when, in the
sole judgement of BioMarin, such action is necessary, proper and justified. If
within sixty (60) days after written request by IBEX, BioMarin elects not to
enforce any of the Assigned Patent Rights against any third party, IBEX shall
have the right, but not the obligation, upon the written approval of BioMarin to

                                       6


seek to enforce the Assigned Patent Rights against such third party. BioMarin
shall have the right to reasonably withhold its approval of such enforcement of
the Assigned Patent Rights if BioMarin believes that such enforcement would have
an adverse impact upon the scope or the validity of the Assigned Patent Rights.

                  In the event that BioMarin approves IBEX's right to enforce
the Assigned Patent Rights in accordance with this Section 8.01, IBEX shall
consult with BioMarin and keep BioMarin regularly advised of IBEX's strategies,
plans, progress and results of any such enforcement action, and IBEX shall bear
all associated costs and expenses. IBEX shall not enter into any settlement
action or agree to any settlement arrangement, or take any action that may
negatively impact the Assigned Patent Rights, without the express prior written
consent of BioMarin.

              8.02  IBEX will promptly notify BioMarin upon becoming aware of
(a) any third party claim or action against IBEX and/or BioMarin for
infringement of third party Patent Rights through the making, using or selling
Licensed Products or (b) any third party infringement of the Assigned Patent
Rights, and provide BioMarin of evidence of the alleged infringement. BioMarin
shall have the sole right and discretion with respect to preventing and/or
causing the discontinuance of any infringement of the Assigned Patent Rights.
IBEX agrees that it will, at BioMarin's request and expense, furnish such
reasonable assistance as may be required to assist in preventing or
discontinuing any such infringement.


                        ARTICLE IX - TERM AND TERMINATION
                        ---------------------------------

              9.01  This Agreement shall become effective as of the Effective
Date and, unless earlier terminated, the Agreement shall remain in full force

accordance with Article III, the license granted pursuant to Article III with
respect to such Limited Therapeutic Licensed Product shall remain in full force
and effect through the expiration of the Term.

              9.02  BioMarin shall have the right to terminate this Agreement in
the event of material breach or default by IBEX if such breach or default has

breach to BioMarin.

              9.03  Immediately upon the consummation of a transaction (a "Third
Party Transaction") whereby IBEX assigns, transfers or sublicenses all or a
material portion of its rights under Article III hereunder to a third party,
IBEX hereby acknowledges and agrees that BioMarin shall be entitled to fifty
percent of all payments received by IBEX in connection with such Third Party
Transaction (including without limitation up-front payments, license fees,
royalties, shares of profits and milestone payments). In the case of a Third
Party Transaction involving a merger, consolidation, share exchange, business
combination or other similar transaction (a "Third Party Acquisition"), the
calculation of payments in subsection (a) of the preceding sentence shall be
made based upon the allocation of the purchase price in the Third Party
Acquisition to the rights licensed to IBEX under Article III.

Patent Rights.

              9.05  At BioMarin's option, IBEX shall upon termination of this
Agreement either return to BioMarin all Confidential Information of BioMarin's
received by IBEX pursuant to this Agreement, or certify that such information
has been destroyed. Notwithstanding the preceding, IBEX would be permitted to
retain one copy of the BioMarin Confidential Information, solely for record
purposes.

              9.06  Expiration or termination of this Agreement shall not
discharge, affect or modify any rights or obligations which accrue or are
incurred prior to the date of expiration or termination.

              9.07  Articles I, V, VI, IX, X and XI shall survive any expiration
or termination of this Agreement.

                  NOW, THEREFORE, in consideration of the premises and the
representations, covenants and agreements contained herein, and for other good
and valuable consideration, the receipt and adequacy of which are hereby
acknowledged, the parties hereto hereby agree as follows:

              1.     Non-Competition. Each of the Members of the IBEX Group and
their respective officers, directors, and affiliates (the "Vendor Group") hereby
agrees that during the Term (as defined below) they will not, acting alone or as
a member of a firm, corporation, partnership, limited liability company or other
business entity (whether as an advisor, principal, employee, officer, director,
consultant, independent contractor, agent, partner, 3% or greater equity holder
or otherwise):

                     a.   engage in, own, operate, maintain or finance any
business or other enterprise directly or indirectly in competition with the IBEX
Pharma Canadian Business (as defined in the Canadian Purchase Agreement) or the
IBEX Group Worldwide Business (as defined in the United States Purchase
Agreement) anywhere in the Territory (as defined below) (the "Prohibited
Business"); or

                     b   recruit or otherwise solicit or induce any employee,
customer, subscriber or supplier of the BioMarin Group who operates as such
anywhere in the Territory to terminate its employment with or arrangement for
the provision of services by or to the BioMarin Group, or otherwise to cease any
of its relationships with the BioMarin Group.

For purposes of this Agreement, "Term" shall mean the period commencing on the
date hereof and continuing for a period of five (5) years thereafter and
"Territory" shall mean all of the geographic territory in which BioMarin
currently or hereafter operates its business (including its operation of the
business formerly comprising the IBEX Pharma Canadian Business and the IBEX
Group Worldwide Business).

                  The parties hereto acknowledge and agree that the operation of
the Excluded Assets by any of the Members of the IBEX Group shall not constitute
the Prohibited Business and shall not constitute a violation of the covenants
contained in clause (a) above.

              2.     Relief. Each of the Members of the IBEX Group acknowledges
that the terms and conditions of this Agreement are reasonable and necessary to
protect the legitimate interests of the BioMarin Group and that any violation of
such terms or conditions would result in irreparable injury to the BioMarin
Group. Each of the Members of the IBEX Group agrees that the members of the
BioMarin Group do not have an adequate remedy at law for any breach or
threatened breach or attempted breach of the covenants and agreements set forth
in this Agreement and, accordingly, each of the Members of the IBEX Group agrees
that the BioMarin Group may, in addition to other remedies that may be available
under this Agreement, the Canadian Purchase Agreement, the United States

                                       2


Purchase Agreement or at law, commence proceedings in equity for an injunction
temporarily or permanently enjoining each of the Members of the IBEX Group from
breaching or threatening or attempting any such breach of such covenants and
agreements and each of the Members of the IBEX Group hereby consents to the
issuance of such injunction.

              3.     Severability. In the event that the provisions of this
Agreement shall be determined by a court of competent jurisdiction to be overly
broad by reason of the length of the period of time set forth therein or the
size of the area affected thereby, such court may reduce such period of time or
such area, or both, to a period of time or area which it deems reasonable under
the circumstances. If any one or more provisions hereof are held to be invalid
or unenforceable, the validity of the remaining provisions shall not be affected
thereby.

              4.     Representations and Warranties. Each of the Members of the

                  --------------------------------------

                  4.1    Trademarks, etc. Neither party shall use the other
party's tradenames, trademarks or the names of the other party's employees
without securing the prior written consent of the other party, which consent may
be unreasonably withheld.

                  4.2    Ownership. Each party retains sole ownership of its
respective tradenames, trademarks, patents, and other intellectual property and
no license thereto shall be deemed granted by either party to the other for such

the Term.

                  4.3    Confidential Information. During the Term and for a
period of five (5) years thereafter each party shall keep confidential all
proprietary or confidential information (the "Confidential Information")
obtained from the other party or its representatives in connection with the
other party and this Agreement. The term "Confidential Information" shall not
include any information which: (i) is or becomes generally available to the
public other than as a result of a disclosure by the receiving party or the
representatives; (ii) becomes known to the receiving party or the
representatives on a non-confidential basis from a source (other than the

Information in its possession regarding the other party and all copies and
extracts thereof or with the consent of the other party shall destroy all such
Confidential Information and copies and extracts and shall deliver to the other
party evidence of destruction of such Confidential Information and copies and

Section 4.3, the members of the BioMarin Group shall be one party and the

Fee are set forth in the Allocated Space on Exhibit D attached hereto. The
parties agree that, upon sixty (60) days' advance notice, the parties shall be

(5) days following the end of the month for which such costs are incurred, and
IBEX shall apply such payments to the payment of any rent due the landlord for
the IBEX Facility. The IBEX Group covenants and agrees that it shall be solely

                                       3


responsible for paying any and all amounts due under the lease with the landlord
of the IBEX Facility. The IBEX Group hereby indemnifies, and holds the BioMarin

amounts.

Group a monthly fee (the "Equipment Fee") in the amount of fifty percent (50%)
of the service and maintenance costs of the Lab Equipment that has been made
available to the BioMarin Group in the preceding month. The BioMarin Group shall
pay to IBEX the Equipment Fee at the same time as the Space Fee, and IBEX shall
apply such payments to the payment of any amounts due the equipment lessor for
the Lab Equipment. The IBEX Group covenants and agrees that it shall be solely
responsible for paying any and all amounts due under the equipment lease with
the equipment lessor for the Lab Equipment. The IBEX Group hereby indemnifies,
and holds the BioMarin Group harmless, from and against any liabilities related
to failure to pay such amounts.

                  5.3    Services Fee. In consideration of any services provided
in accordance with Section 3.2, the BioMarin Group will pay the IBEX Group the
amounts calculated in accordance with Exhibit C (the "Services Fee"). Any such
Services Fees shall be paid monthly within fifteen (15) days after receipt of an
invoice from IBEX.

Dear Sirs:

We have acted as counsel to IBEX Technologies Inc. ("IBEX"), IBEX
Pharmaceuticals Inc. ("IBEX Pharma") and Technologies IBEX R&D Inc. ("IBEX R&D")
(IBEX, IBEX Pharma and IBEX R&D being collectively referred to herein as the
"IBEX Canadian Companies") and IBEX Technologies LLC ("IBEX LLC") and IBEX

IBEX Corp. being collectively referred to herein as the "IBEX Group") in
connection with the preparation, execution and delivery of a Canadian Asset
Purchase Agreement dated as of o, 2001 (the "Canadian Agreement"), by and among
the members of the IBEX Group and BioMarin Pharmaceutical Inc. ("BioMarin") and
BioMarin Pharmaceutical Nova Scotia Company ("BioMarin NS") (collectively, the
"BioMarin Group"). IBEX LLC and IBEX Corp are collectively referred to herein as
the "IBEX US Companies".

This opinion is delivered to you pursuant to the Canadian Agreement. Capitalized

In connection with this opinion, we have examined originals or copies certified

         dated as of the date hereof, a copy of which is attached hereto (the

We have examined originals or copies, certified or identified to our
satisfaction, of the constating documents and by-laws of each of the IBEX
Canadian Companies and of such corporate records of each of the IBEX Canadian
Companies, certificates of public officials, officers of each of the members of
the IBEX Group and such other documents and have considered such questions of

                                                                          Page 3


As to questions of fact relevant to this opinion, we have assumed the accuracy
of the representations and warranties of the members of the IBEX Group in the
Documents and we assume compliance on the part of all Parties with their
covenants and agreements contained therein.

We are qualified to carry on the practice of law in the Province of Quebec only
and we express no opinion as to any laws or matters governed by any laws, other
than the laws of the Province of Quebec and the federal laws of Canada
applicable therein. The opinions herein are limited to the laws of the Province
of Quebec and the federal laws of Canada applicable herein in effect as of the
date hereof and we assume no obligation to update these opinions to take into
account any changes in such laws after the date hereof.

In expressing the opinion set forth in paragraph 1 below, we have relied
exclusively on the IBEX Good Standing Certificate, the IBEX Pharma Good Standing
Certificate and the IBEX R&D Good Standing Certificate.

The phrase "to our knowledge" when used in this opinion is intended to indicate
that, during the course of our representation of the members of the IBEX Group,
no information that would give us actual knowledge (as at the date hereof) of
the inaccuracy of such opinions has come to the attention of the lawyers
advising the members of the IBEX Group.

Based upon and subject to the foregoing and the qualifications set forth below,
we are of the opinion that:

1.       Each of the IBEX Canadian Companies is duly incorporated under the laws
         of its respective jurisdiction of incorporation and has not been
         dissolved.

2.       Each of the IBEX Canadian Companies has all necessary corporate power,
         authority and capacity to own, lease and operate its respective
         property and assets and to execute, deliver and perform each of the
         Documents and the License Agreement. Each of the IBEX Canadian
         Companies has received all necessary corporate approvals in connection
         with the execution, delivery and performance of each of the Documents
         and the License Agreement.

3.       To our knowledge there are no outstanding options, rights, calls,
         commitments, conversion rights, plans or other agreements of any
         character providing for the purchase, issuance, sale or transfer of any
         of the Canadian Assets.

4.       The execution, delivery and performance by each of the IBEX Canadian
         Companies of each of the Documents and the License Agreement and the
         consummation of the Transaction will not; (i) violate, conflict with or
         result in the breach of any of the terms, conditions or provisions of
         the certificate of incorporation or the by-laws of any of the IBEX
         Canadian Companies; or (ii) subject to the Bulk Sales Carve-out,
         contravene any laws of the Province of Quebec; or (iii) to our


                                                                          Page 4


         knowledge, contravene any order, writ, injunction or decree of any
         court or other governmental authority to which any of the IBEX Canadian
         Companies is subject; and (iv) to our knowledge, neither of the
         Documents nor the License Agreement contravenes any indenture,
         agreement, instrument or understanding to which any of the IBEX
         Canadian Companies is a party or by which any of the IBEX Canadian
         Companies is bound.

5.       The execution, delivery and performance by each of the IBEX US
         Companies of the Documents and the License Agreement and the
         consummation of the Transaction will not; (i) subject to the Bulk Sales
         Carve-Out, contravene any laws of the Province of Quebec; (ii) to our
         knowledge, contravene any order, writ, injunction or decree of any
         court or other governmental authority to which either of the IBEX US
         Companies is subject; and (iii) to our knowledge, neither of the
         Documents nor the License Agreement contravenes any indenture,
         agreement, instrument or understanding to which either of the IBEX US
         Companies is a party or by which either of the IBEX US Companies is
         bound.

6.       Save and except as provided in the Documents and/or the License
         Agreement, no authorization, consent or approval of, or filing with or
         notice to; (i) any governmental agency or regulatory body; or (ii) to
         our knowledge, any court or other Person; is required to be obtained by
         any member of the IBEX Group in connection with the execution, delivery
         or performance of the Documents and.or the License Agreement by each
         member of the IBEX Group.

7.       To our knowledge, save and except as provided in the Canadian
         Agreement, there is no action, suit, litigation, arbitration or
         proceeding in progress or pending against or relating to any member of
         the IBEX Group nor are we aware of any judgment, decree, injunction or
         order of any court, government department, commission, agency or
         arbitration outstanding against any member of the IBEX Group.

8.       Each of the Documents and the License Agreement has been duly executed
         and delivered by each member of the IBEX Group.

9.       Each of the Documents is a legal, valid and binding obligation of each
         member of the IBEX Group, enforceable against each member of the IBEX
         Group in accordance with its terms.

The opinion set forth in section 9 above is subject to the qualifications that:

BioMarin To Acquire Enzyme Products From IBEX Technologies

 Neutralase(TM) to Enter Phase III Clinical Program for Coronary Artery Bypass
             Graft;Phenylase in Preclinical Development for Phenylketonuria

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

     Novato, California, October 10, 2001 - BioMarin Pharmaceutical Inc. (Nasdaq
and SWX New Market: BMRN) today announced that it has reached a definitive
agreement with IBEX Technologies Inc. (Toronto Stock Exchange: IBT) to acquire
the rights to all IBEX pharmaceutical assets. IBEX's portfolio of enzyme
therapeutics will complement BioMarin's existing pipeline of products for
serious, life-threatening diseases and conditions.


     New Product Additions to the BioMarin Pipeline

     IBEX's lead product, NeutralaseTM, is an injectable heparinase
that reverses the anticoagulation of blood by heparin and other new heparin-like
anticoagulants. Neutralase is a carbohydrate-modifying enzyme that cleaves
heparin, a glycosaminoglycan (GAG), in a manner similar to the activity of
BioMarin's two enzyme replacement therapies: AldurazymeTM for the treatment of
MPS I and rhASB for the treatment of MPS VI. Based on positive safety and
efficacy data from IBEX's clinical trials of Neutralase, BioMarin plans to
initiate a Phase III trial of Neutralase in Coronary Artery Bypass Graft (CABG)
surgery in 2002.

     In addition, IBEX has an early development stage program for Phenylase, an
orally active enzyme with the potential to treat Phenylketonuria (PKU), a
genetic disease caused by an enzyme deficiency that can lead to progressive,
severe, and irreversible mental retardation.


     Terms of the Agreement

     Under the terms of the agreement, BioMarin will acquire IBEX's
pharmaceutical assets for US$10.5 million, with all but US$2 million payable in
shares of BioMarin common stock.

     BioMarin will also make contingent payments of up to US$9.5 million to IBEX
upon U.S. FDA approval of products acquired from IBEX.

     The boards of directors of BioMarin and IBEX have approved the
transaction, which is subject to customary closing conditions. The transaction
is expected to close in the fourth quarter of this year. Leerink Swann & Co.
acted as financial advisor to BioMarin with regard to this transaction.

     Fredric D. Price, BioMarin's Chairman and Chief Executive Officer said,
"Neutralase and Phenylase represent novel approaches to solving
medically-important problems that affect hundreds of thousands of patients in
North America and Europe. The acquisition of these promising compounds further
expands BioMarin's portfolio of treatments developed through our enzyme and
carbohydrate chemistry expertise.

     "Neutralase is a unique late-stage product with the potential to
significantly reduce the serious problems associated with heparin reversal. With
the addition of Neutralase, BioMarin will have five drug candidates in clinical
trials next year: Aldurazyme, rhASB, Vibriolysin, Neutralase, and a fifth
product that will advance from our internal development pipeline."

     Robert Heft, Ph.D., Co-founder, President, and Chief Operating Officer of
IBEX, added, "BioMarin's expertise in enzyme research, production, quality
control and assurance, process development, and clinical trials management will
greatly enhance the ability to effectively advance Neutralase and Phenylase
through their next stages of development. I am looking forward to assuming my
new position as Vice President, Product Development at BioMarin and
contributing, with my team here in Montreal, to BioMarin's success."


     Background on Neutralase and Phenylase Markets

     There are approximately 300,000 CABG procedures and 725,000 angioplasties
each year in the United States that could potentially benefit from heparin
reversal. Estimates for the European markets are projected to be as large as
those in the U.S. In addition, preclinical studies have shown that Neutralase
may be effective as a reversal agent for the low molecular weight heparins
(LMWHs) that are used in many surgeries such as hip and knee replacements as
well as for a new class of drugs, pentasaccharides, that are also being
developed for these indications.

     Currently, protamine is the only product available for the reversal of
heparin anticoagulation. Protamine has been known to cause significant problems
during the reversal of heparin anticoagulation, but it has continued to be used
in the absence of an appropriate alternative. According to numerous published
articles, risks associated with protamine usage include: sudden decreases in
blood pressure, depression of heart function, pulmonary hypertension, acute
allergic reactions, complement activation, and strokes. IBEX's clinical trials
have demonstrated that Neutralase adequately reverses heparin anticoagulation
and improves blood pressure characteristics when compared to protamine.
Additional data suggest that Neutralase may address other serious problems that
have been linked to protamine usage as well.

     Jeffrey Borer, M.D., Chief, Division of Cardiovascular Pathophysiology,
Weill Medical College of Cornell University, noted, "Protamine complications
during heart surgery are well known, but currently there are no other heparin
antidotes. In clinical testing during open heart surgery, Neutralase has
demonstrated the potential of being an effective alternative to protamine
without its unwanted hemodynamic complications."

     Jean-Francois Tanguay, M.D., Montreal Heart Institute, and principal
investigator for IBEX's Phase II trial of Neutralase in angioplasty, commented,
"Heparin reversal following angioplasty is uncommon because of the lack of a
suitable drug. Initial clinical evaluation in patients undergoing angioplasty
demonstrated that Neutralase has the ability to significantly reduce the time to
sheath removal and the time required for safe patient ambulation."

     PKU affects approximately 50,000 patients in North America and Europe.
There are no drugs currently approved for treatment of PKU, and patients are
required to adhere to strict, protein avoiding diets. The special formulas and
foods are estimated to cost more than $5,000 per patient per year over normal
food requirements. Many patients over five to ten years of age have difficulty
maintaining this dietary regimen, and their elevated phenylalanine levels lead
to a variety of problems with brain function. Phenylase is an oral enzyme
therapy that has the potential to reduce phenylalanine levels while allowing a
less restricted, more palatable diet.

     Charles R. Scriver, M.D., Alva Professor of Human Genetics, McGill
University, said, "Up to now, treatment of thousands of PKU patients has been
accomplished by changing lifestyle, diet and the intake of protein and
phenylalanine. Almost fifty years of dietary treatment reveal how arduous and
difficult it is. Oral enzyme substitution therapy with Phenylase has been
demonstrated in a PKU animal model. It is time to move Phenylase forward so that
it can be studied and used in the human patient."

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

                          BioMarin Pharmaceutical Inc.

              QUESTIONS AND ANSWERS RELATING TO THE ACQUISITION OF

                 NEUTRALASE AND PHENYLASE FROM IBEX TECHNOLOGIES
--------------------------------------------------------------------------------

QUESTIONS ON NEUTRALASE


1. Question:  What kind of an enzyme is Neutralase and how does it work?

         Answer: Neutralase (heparinase I) is a carbohydrate-modifying enzyme
that cleaves heparin at specific places important for anticoagulation. By
cleaving heparin, Neutralase reverses heparin's anticoagulative effects.
Importantly, Neutralase can also cleave and neutralize the anticoagulative
effects of the new low molecular weight heparins (LMWHs) and the synthetic
heparin-like pentasaccharide Arixtra(R) (fondaparinux sodium) from
Sanofi-Synthelabo and Organon. We believe that no product other than Neutralase
will have the capability of reversing all of these new products.


2. Question:  How does Neutralase fit into BioMarin's pipeline of enzyme
products?

         Answer: Like all of our existing products that treat genetic diseases,
Neutralase is a carbohydrate-modifying enzyme. It cleaves heparin, a type of
glycosaminoglycan or `GAG' (carbohydrate). Our two lead products - Aldurazyme
for MPS I and rhASB for MPS VI - also cleave GAGs.


3. Question:  What are the potential indications for Neutralase and what is its
competition?

         Answer: Neutralase has the potential for use as a reversal agent for
heparin anticoagulation in open-heart surgery such as coronary artery bypass
graft (CABG) procedures, interventional cardiology procedures such as
angioplasty, and whenever heparin or heparin-like anticoagulants need reversal.
Protamine sulfate is the only agent currently available to reverse heparin and
its use is associated with numerous side effects as detailed in question number
four below. In addition, protamine cannot efficiently reverse the activity of
low molecular weight heparins, heparinoids or Arixtra. Neutralase, on the other
hand, has been shown to reverse these newer anticoagulation products in
preliminary trials (Yang et al., 1986; Jeske and Fareed, 1999; Zmuda et al.,
2000; Daud et al., 2001; Yu et al., 2000).

Protamine is used more than 2,000,000 times annually (Carr and Silverman, 1999)
in the U.S. alone, and Neutralase could potentially be used to reverse heparin
in all of these situations as well as in the other situations in which reversal
of heparin is currently avoided due to protamine's side effects.





4. Question:  What is protamine and what problems associated with its use
complicate and limit its utility?

         Answer:  Protamine is a positively charged polymer derived from salmon
sperm that inactivates heparin by binding to it, forming large macromolecular
complexes. Protamine has been known to cause significant problems during
reversal of heparin anticoagulation, but it has continued to be used in the
absence of an appropriate alternative (Carr and Silverman, 1999; Weiler et al.,
1985; Weiler et al., 1990; Kimmel et al., 1998). Some of these known problems
are detailed below:


     o        Sudden decreases in blood pressure. Protamine is known to
              cause sudden decreases in blood pressure during administration for
              reversal of heparin during bypass surgery. This effect may be due
              to the large protamine-heparin complex that causes the release of
              mediators that dilate blood vessels and lower blood pressure. In
              addition, it may have a direct effect on decreasing cardiac
              function (Del Re et al., 1993; Carr and Silverman, 1999).
              Anesthesiologists must infuse protamine slowly and provide
              immediate blood pressure support in patients during heparin
              reversal after open-heart surgery in order to try to manage this
              common problem.

     o        Increased pulmonary blood pressure (pulmonary
              hypertension). The reversal of heparin with protamine routinely
              induces sudden increases in pulmonary blood pressure (pulmonary
              hypertension) due to the release of mediators, such as
              thromboxane, which can put excess strain on the heart immediately
              following surgery and lead to catastrophic consequences (Morel et
              al., 1987; Lowenstein and Zapol, 1990; Carr and Silverman, 1999).

     o        Acute allergic reactions. Most patients having acute
              allergic reactions to protamine have not had prior protamine
              exposure and have no known predisposing condition. Patients with
              prior exposure to protamine, such as diabetics using
              protamine-formulated insulin (also called NPH), can have acute
              anaphylaxis reactions during heparin reversal with protamine
              (Weiss et al., 1989; Porsche and Brenner, 1999). A study by Gupta
              et al 1986 found that 3% of all insulin dependent diabetics and
              0.2% of all persons undergoing vascular surgery at their
              institution had anaphylactoid reactions to protamine and an
              associated overall mortality rate of 36%. Though less common,
              these allergic reactions can be severe.

     o        Complement activation. The large protamine-heparin
              complexes formed after protamine administration can activate the
              classical complement pathway, a type of inflammatory immune
              response (Morel et al., 1987; Carr and Silverman, 1999). The
              activation of complement components and subsequent complement
              cascade has been associated with post-operative arrhythmias
              (Bruins et al., 2000). Indiscriminate activation of complement can
              cause tissue injury, as the complement cascade leads to the






              production of activated complement complexes that bind and attack
              tissues and release secondary mediators, such as thromboxane.
              These actions are associated with temporary organ dysfunction and
              morbidity after surgery.

     o        Platelet dysfunction and leukocyte sequestration.
              Protamine alters the function of platelets and leukocytes and
              associated cell surface receptor expression which leads to
              decreased or abnormal platelets and decreased leukocytes
              (Mochizuki et al., 1998; Ammar and Fisher, 1997).

     o        Strokes when used in carotid endarterectomy (CEA).
              Protamine is often avoided in vascular surgery because it can
              promote clot formation at the surgical site. Mauney et al (Mauney
              et al., 1995) published a report on a consecutive series of 348
              patients undergoing carotid surgery and found a postoperative
              stroke rate of 2.6% when protamine was used versus no strokes
              without protamine.


5. Question:  What are the most important results from the Neutralase Phase I
and II clinical trials?

         Answer: The Phase I and Phase II clinical trials described below
indicated that the drug was safe, well tolerated and effective at reversing
anticoagulation by heparin in a dose-dependent fashion. The data show that
Neutralase can reverse heparin anticoagulation with fewer decreases in systolic
blood pressure and fewer increases in pulmonary blood pressure than protamine.

     o        Results from use in CABG surgery.  A Phase II study using a dose
              of 10 ug/kg or 15 ug/kg demonstrated successful reversal of
              heparin. This trial was initiated to assess a higher baseline
              dose of Neutralase and an improved regimen for re-administration
              more in line with current clinical practice. Seventeen hospitals
              in the U.S. and Germany participated in the first stage of the
              trial. The interim analysis was conducted after the first 94
              patients undergoing CABG surgery were enrolled. In the study,
              patients were randomly assigned to one of three treatment arms -
              Neutralase 10 ug/kg, Neutralase 15 ug/kg, or protamine - in a
              double blind, controlled comparison of Neutralase to protamine.
              The study demonstrated adequate reversal with both the 10 ug/kg
              and 15 ug/kg doses of Neutralase and again reaffirmed the
              improved blood pressure characteristics of reversal with
              Neutralase over protamine. The data suggested that a similar but
              larger Phase III trial would meet its endpoint of no significant
              difference (difference of < 300 cc) in chest tube drainage.


     o        Results from use in angioplasty. A Phase II trial in
              angioplasty demonstrated that the patients could complete the
              procedure faster (removal of the vascular sheath one and a half to
              two hours sooner) and ambulate three to four hours sooner (Tanguay
              et al., 2001).





6. Question:  What happened to the first Phase III Neutralase trials initiated
by IBEX

         Answer: An inadequate dose and dosing regimen were used in the first
Phase III trial and led to inadequate reversal of heparin. An appropriate dose
and dosing regimen have been determined based on the Phase II trial noted above
and will be used in subsequent trials. Additional detail is provided below.

The initial Phase III trial in CABG showed that the dose used (7 ug/kg) and the
dosing regimen were not sufficient to completely reverse heparin in comparison
to protamine. In the first Phase III, the criterion for clinically successful
reversal was an activated clotting time of less than 20 seconds. This criterion
was not stringent enough and allowed some patients to receive an inadequate dose
of Neutralase. In addition, the protocol did not take into account specific
common practices in CABG such as the return of heparinized pump blood to the
patient, which would necessarily require more reversal agent. The Phase III
trial was stopped after 169 total patients were enrolled due to increased chest
tube drainage and unfavorable re-operation rates compared with protamine. In
spite of these dosing-related issues, the decreased incidence of blood pressure
problems after reversal was observed with Neutralase in comparison to protamine.


7. Question:  Which indication will BioMarin pursue first, why, and what other
indications might it pursue?

         Answer: BioMarin plans to initiate a Phase III trial of Neutralase in
the CABG indication first in 2002, because the use of Neutralase in CABG is the
most advanced clinical development program. CABG is performed over 600,000 times
in the U.S. and Europe each year and reversal of heparin is required in all
procedures performed using heart-lung bypass.

Subsequent to initiating the Phase III trial related to CABG, BioMarin intends
to pursue the use of Neutralase in angioplasty. Angioplasty is performed
approximately 1.4 million times in the U.S. and Europe annually. Currently,
heparin is used in angioplasty procedures to prevent thrombosis during or after
the procedure. Protamine is avoided because it can cause thrombosis and blockage
of the artery just opened. By avoiding protamine, the patient remains
anticoagulated for hours after the procedure. The patient usually lies in bed
with a sandbag on the groin waiting for the heparin to dissipate on its own
before the sheath is removed and the patient can ambulate. Neutralase has been
shown in a Phase II trial to safely reverse heparin and allow earlier sheath
removal and earlier ambulation (Tanguay et al., 2001). Reversal with Neutralase
retains some of the residual anti-thrombosis effect of heparin (known as anti-Xa
activity), which is a further advantage of using Neutralase for this indication.





8.  Question:  In addition to reversing  heparin,  does  Neutralase  have the
potential to reverse the new agents such as Low Molecular Weight Heparins
(LMWHs) and Arixtra (the new pentasaccharide from Sanofi/Organon)?

         Answer: Neutralase is the only agent known to efficiently reverse these
new heparin-like anti-clotting agents. Neutralase is able to inactivate these
agents because it cleaves the recognition site for anti-thrombin III. The
binding of anti-thrombin III to these agents is required for the inhibition of
coagulation enzymes such as Factor IIa and Factor Xa. Neutralase can cleave
Arixtra, the new pentasaccharide agent from Sanofi, into an inactive trimer and
a dimer (Daud et al., 2001; Yu et al., 2000). Protamine does not work at all on
Arixtra and works poorly on the other low molecular weight compounds. It has a
relatively low affinity to bind these small heparin-like molecules


9. Question:  How is Neutralase manufactured?

         Answer: Neutralase is manufactured in large-scale batch culture of
Flavobacterium heparinium in native or recombinant form. IBEX successfully
manufactured clinical product through the use of a contract manufacturer at
commercial 2,000 liter scale. BioMarin believes this manufacturing process will
be further scaleable to larger commercial production levels.


10. Question:  What is the Neutralase intellectual property position?

         Answer:  Neutralase is protected by a collection of patents regarding
the heparinase enzyme, composition of matter, method of use, and methods of
production.


QUESTIONS ON PHENYLASE


1. Question:  What kind of an enzyme is Phenylase and how does it work?

         Answer: Phenylase is a special stabilized microcrystalline form of the
enzyme phenylalanine ammonia lyase (PAL). Phenylase is designed to destroy
phenylalanine in the gut after oral administration. In doing so, it treats the
phenylketonuria (PKU) patient by lowering blood phenylalanine levels, which are
elevated in these patients.


2. Question:  What is the indication for Phenylase?

         Answer: Phenylase is being developed as an oral enzyme therapy for
patients with PKU. PKU is a genetic disease in which the body cannot properly
metabolize phenylalanine. The elevated levels of phenylalanine lead to brain
damage and severe mental retardation if left untreated. There are about 50,000
patients in the US and Europe with PKU. Patients with PKU are diagnosed at birth





by newborn screening and their phenylalanine levels are controlled by
restrictive diet. With adequate control, brain damage can be avoided. Phenylase
is currently in the preclinical stage of development.


3. Question:  What do patients do today since there are no approved drugs on the
market?

         Answer: The current standard of care for PKU is dietary control of
phenylalanine intake. A phenlyalanine free diet is easy to maintain in babies on
formula but is difficult and expensive later in life. Older patients use a
special phenylalanine free formula as their main food item and supplement that
with expensive special foods that are engineered to be low in phenylalanine. The
special dietary foods are expensive, costing more than $5,000 per year, and are
unpalatable for many patients. Most school age children, teenagers, and adults
have difficulty maintaining the degree of control over phenylalanine intake
recommended to achieve adequate protection of the brain. Teenagers and adults
frequently go off the diet in spite of the fact that the phenylalanine control
is now recommended for life (Phenylketonuria NIH consensus statement). Phenylase
has the potential to provide a convenient oral medication that would allow
patients to eat a normal diet and maintain a better degree of control of
phenylalanine intake.
