                     ABOUT BIOJECT MEDICAL TECHNOLOGIES INC.

We develop,  manufacture and market jet injection  systems for needle-free  drug
delivery. We sell our products directly to healthcare providers. We also license
our technology to leading  pharmaceutical and biotechnology  companies for whose
products our technology  provides  increased medical efficacy or enhanced market
acceptance.

Our needle-free operations are conducted by Bioject Inc., an Oregon corporation,
which is our wholly owned subsidiary. Bioject Inc. commenced operations in 1985.
Bioject  Medical  Technologies  Inc.  was formed in  December  1992 for the sole
purpose of acquiring  all the capital stock of Bioject  Medical  Systems Ltd., a
company   organized  under  the  laws  of  British   Columbia,   Canada,   in  a
stock-for-stock  exchange.  This stock acquisition  established  Bioject Medical
Technologies Inc., a U.S. domestic  corporation,  as the publicly-traded  parent
company of Bioject Inc. and Bioject Medical Systems Ltd. Bioject Medical Systems
Ltd.  was  then  terminated  in  fiscal  1997.  Our  blood  glucose   monitoring
development  operations  were conducted by Marathon  Medical  Technologies  Inc.
("Marathon   Medical")   (formerly   Bioject  JV  Subsidiary  Inc.),  an  Oregon
corporation,  which is our wholly owned subsidiary. The blood glucose monitoring
development  operation was  discontinued in June 1999. All references to Bioject
are to  Bioject  Medical  Technologies  Inc.  and its  subsidiaries,  unless the
context  requires  otherwise.  Bioject's  executive  offices and  operations are
located at 7620 SW Bridgeport  Road,  Portland,  Oregon 97224, and our telephone
number is (503) 639-7221.

We  manufacture  and market a professional  needle-free  injection  system,  the
Biojector(R)  2000, which allows healthcare  professionals to inject medications
through the skin, both  intramuscularly  and  subcutaneously,  without a needle.
Using this technology to administer  injections virtually eliminates the risk of
contaminated   needlestick  injuries  and  the  resulting  blood-borne  pathogen
transmission,  which is a major concern throughout the healthcare industry.  The
Biojector  2000  system  consists  of  two  components:  a  handheld,   reusable
jet-injector  (the  "Biojector  2000" or  "B-2000")  and a  sterile,  single-use
disposable syringe (the "Biojector  syringe").  We also manufacture and market a
device  that  allows the  Biojector  syringe to be filled  without a needle (the
"Vial  Adapter").  The Vial Adapter may be purchased  either  separately or as a
pre-packaged  component of the B-2000  system.  The B-2000  system is capable of
delivering  needle-free  injections  in  varying  doses up to 1 ml.  We has also
developed  the B-2020 and B-4000  jet-injection  systems.  The B-2020  system is
similar  in design  and  intended  use to the B-2000  system  except  that it is
designed to deliver  injections in varying doses up to 1.5 ml. The B-4000 system
is intended to be used by  non-professionals  to  self-administer  injections of
various  medications  in  varying  doses up to 1 ml.  We have  not yet  received
regulatory  clearance to begin selling either the B-2020 or the B-4000  systems.
We  are  also  developing  a  single-use  disposable  and  multi-use  disposable
injector,   the  "Iject"  intended  to  be  used  by  both   professionals   and
non-professionals  to either administer or  self-administer  medications up to 1
ml. We have not yet applied for regulatory clearance for this product.

We also  market the Vitajet 3 (R)  ("Vitajet"),  a  spring-powered,  needle-free
self-injection  device,  the rights to which were acquired in a transaction with
Vitajet  Corporation  in  March  1998.  The  Vitajet  currently  has  regulatory
clearance for administering injections of insulin.

Our long-term  goal is to establish  our  needle-free  injection  systems as the
preferred drug delivery method for all medications administered by intramuscular
or subcutaneous injection. Bioject focuses its current product sales efforts for
the Biojector 2000 system on: i) flu  immunization  clinics and  providers;  ii)
healthcare providers in states such as California, where legislation is in place
that favors  alternatives  to  needle-syringes;  iii)  potentially  high volume,
national accounts that will use or distribute  Bioject's products across a large
region;  and iv) the U.S.  military.  We are also  focusing  efforts to sell the
B-2000 to multiple sclerosis patients through a distributor.

We  have   established   manufacturing   capability   for  the  Vitajet  at  our
manufacturing  facility in Portland,  Oregon, and plans to enter into agreements
with  distributors  to sell the Vitajet to insulin users. We are also developing
various marketing strategies to sell the Vitajet directly to end-users.

We are actively pursuing  strategic  partnering  relationships  with a number of
pharmaceutical  and  biotechnology  companies  under  which  we  plan  to  grant
specified  rights  or  licenses  to some or all of our  products.  The  strategy
anticipates that the rights or licenses will allow strategic  partners to i) use
the licensed  products for specific  applications  or purposes or ii) market the
licensed products in conjunction with certain of their products.



                                       4

Under a January 1995,  agreement  with Hoffman  LaRoche Inc.  ("Roche")  Bioject
agreed to develop a needle-free  injection  system for Roche to use with certain
of its products.  The B-2020 system was designed as a result of this  agreement.
Bioject  and Roche  intended  that Roche  would be granted  worldwide  rights to
distribute the B-2020 for a specific class of medications.  In June 1999,  Roche
advised  us that  because  of the  additional  time  and cost  required  to gain
regulatory  clearance to use the B-2020 in conjunction  with the Roche drugs and
because  of an  overall  change  in its  marketing  strategy  for the  drugs  in
question,   it  did  not  intend  to  pursue  distributing  the  B-2020  and  is
relinquishing its exclusive rights to the product.

In  September  1997,  we  entered  into a  joint  venture  agreement  with  Elan
Corporation  plc. for the  development  and  commercialization  of certain blood
glucose  monitoring  technology which we licensed from Elan. In May 1999, rather
than continue to fund the cost of its development,  we entered into negotiations
to sell Marathon's blood glucose monitoring technology, and certain fixed assets
related to developing the technology,  to a third party.  The sale was completed
on June 30, 1999.  The gross  proceeds  from the sale were $4 million.  The gain
realized on the sale was approximately $2.9 million,  net of associated expenses
of the transaction and a $500,000  provision for expenses to wind-up  Marathon's
operations.

The terms of the sale of the blood glucose  monitoring  technology  also provide
for Bioject to receive a royalty on net sales of future products,  if any, which
may be developed in the future from the licensed technology. The agreement calls
for a royalty of three  percent of net sales until  Bioject has  received  total
royalty  payments of $10 million.  The agreement then calls for royalty payments
of one percent of net sales  thereafter.  There can be no assurance  that future
products  will be  successfully  developed  from the  blood  glucose  monitoring
technology or that such products, if developed, will be commercially successful.
In  connection  with the sale of the blood  glucose  monitoring  technology,  we
entered into an agreement  with Elan to purchase its 19.9% common stock interest
in Marathon. We now own 100% of Marathon's stock.

In July 1998, we entered into an agreement with Merck & Co. which provided Merck
limited-term rights to use the B-2000 needle-free injection system with selected
Merck vaccines.  As part of the agreement,  Bioject also granted Merck exclusive
rights to  negotiate  a  long-term  license to the B-2000  for  certain  medical
indications.  We  received  $1.5  million  in  non-refundable  fees  under  this
agreement in the fiscal year ended March 31, 1999.  In February  1999,  citing a
refinement in its vaccine development  strategy,  Merck advised us that it would
not continue discussions to seek long-term license rights to our technology.  No
further fees are due to us from Merck pursuant to the agreement.

In June 1999, we entered into a binding  letter  agreement  with Amgen Inc. that
provided for an evaluation of Bioject's  jet injection  technology  for use with
certain  biopharmaceutical  products.  Terms of the agreement provided for up to
$500,000 in licensing and technology fees based upon meeting certain milestones.
On  February  29,  2000,  we entered  into a  development  and  clinical  supply
agreement  with Amgen for the delivery of an Amgen  product  with our  Iject(TM)
needle-free  injection  system.  In connection with the agreement,  Amgen made a
$1.5 million investment in Bioject's common stock.

In October 1999, Bioject announced a strategic alliance with AngioSense, Inc. to
jointly develop  innovative  delivery systems to treat  cardiovascular  disease.
Bioject's  needle-free  drug  delivery  systems will be modified for  delivering
bio-therapeutic  solutions  as a  surgical  instrument  for  minimally  invasive
surgical  procedures  with  several  proprietary  catheters  being  developed by
AngioSense for  catheter-based  cardiology  interventions.  The alliance  grants
AngioSense an exclusive license to Bioject's  Biojector 2000(R) and Vitajet 3(R)
jet  injectors,  as well as a  customized  version  of  Bioject's  Iject(TM),  a
single-use disposable jet injector with a self-contained,  pre-filled medication
cartridge to treat or diagnose cardiac or cardiovascular diseases.  According to
the terms of the agreement, Bioject received an equity position of approximately
10  percent  in  AngioSense  upon  completion  of  certain  product  development
milestones.  In addition to a long-term  manufacturing and supply agreement with
AngioSense,  Bioject will receive  royalties on future product  sales,  and will
receive  significant  funding  to  support  the  development  of the  disposable
injector portion of the AngioSense delivery system.

In December 1999, Bioject and Serono  Laboratories,  Inc., the U.S. affiliate of
Ares-Serono,  S.A., a leading  biotechnology  company  headquartered  in Geneva,
Switzerland,  announced an exclusive license agreement in the U.S. and Canada to
deliver Serono's  Saizen(R)  recombinant  human growth hormone with a customized
version of Bioject's  Vitajet(TM)3  needle-free  delivery system.  In connection
with the agreement, Serono paid an undisclosed license fee to Bioject and signed
a definitive  supply  agreement  that  commences  upon FDA  clearance.  Clinical
studies evaluating the

bioequivalence of Saizen(R)when  delivered with the Bioject needle-free delivery
system have been completed. A 510(k) pre-market  notification has been submitted
to the U.S. Food and Drug Administration (FDA).

A primary focus of our research  efforts is on clinical  research in the area of
DNA-based  vaccines  and  medications.  To the  best of our  knowledge,  our jet
injection  device is being used in two clinical  studies relating to development
of DNA-based medications.  Currently, to the best of our knowledge,  our devices
are being used in more than twenty  DNA-related  clinical research projects both
within and  outside of the United  States.  These  research  projects  are being
conducted by companies leading the development of DNA-based  medications as well
as by the leading universities and governmental institutions conducting research
in this  area.  Included  in these  studies  are a Phase I  clinical  trial of a
DNA-based lymphoma vaccine being conducted at Stanford  University and a Phase I
clinical trial of a DNA-based  malaria vaccine being conducted at the U.S. Naval
Medical  Research  Center.  Preliminary  data from clinical studies with animals
indicates  that  the  use of the  Biojector  technology  may  result  in  better
performance of some DNA-based  medications  than can be achieved  through use of
conventional  needle-syringes.  There can be no assurance that further  clinical
studies  will  prove  conclusively  that our  technology  is more  effective  in
delivering  DNA-based  medications  than  alternative  delivery systems that are
currently available or that may be developed in the future.

In  January  2000,  we filed a resale  registration  statement  on Form S-3,  to
register 164,619 shares of our common stock for resale by selling  shareholders.
The registration statement was declared effective on March 17, 2000. We will not
receive  any  proceeds  from  the  sale of any of the  shares  sold  by  selling
shareholders.

In  February  2000,  we filed a resale  registration  statement  on Form S-3, to
register 372,869 shares of our common stock for resale by selling  shareholders.
The registration statement was declared effective on March 20, 2000. We will not
receive  any  proceeds  from  the  sale of any of the  shares  sold  by  selling
shareholders.

In March 2000, we filed a resale registration statement on Form S-3, to register
the 65,796 shares of common stock issued to Amgen in connection with the license

                           FORWARD-LOOKING STATEMENTS

Certain statements in this Registration Statement and the documents incorporated
by  reference  to  this  Registration   Statement  constitute   "forward-looking
statements" within the meaning of the Private  Securities  Litigation Reform Act
of 1995.  Any  statements  that express or involve  discussions  with respect to
predictions,  expectations, beliefs, plans, projections, objectives, assumptions
or future events or performance  (often, but not always,  using words or phrases
such as "expects" or "does not expect," "is  expected,"  "anticipates"  or "does
not  anticipate,"  "plans,"  "estimates"  or  "intends," or stating that certain
actions,  events or results "may," "could," "would," "might" or "will" be taken,
occur  or be  achieved)  are  not  statements  of  historical  fact  and  may be
"forward-looking  statements." Such forward-looking statements involve known and
unknown  risks,  uncertainties  and other  factors  which  may cause the  actual
results,  performance or achievements  of Bioject,  or industry  results,  to be
materially  different  from any future  results,  performance,  or  achievements
expressed   or  implied  by  such   forward-looking   statements.   Such  risks,
uncertainties  and factors  include,  among others,  those described under "Risk
Factors" and identified as risks or uncertainties in the documents  incorporated
by reference.

                                  RISK FACTORS

An investment in the Shares  involves a high degree of risk. You should consider
carefully the following  risk factors,  together with the other  information  in
this Prospectus, before buying any Shares. You should also be aware that certain
statements  contained  in this  Prospectus  that are not  related to  historical
results are forward-looking  statements.  These forward-looking statements, such
as statements of our strategies, plans, objectives, expectations and intentions,
involve risks and uncertainties. Our actual results could differ materially from
those anticipated in these forward-looking statements.

If our  products are not accepted by the market,  our business  could fail.  Our
success  will depend on market  acceptance  of our  needle-free  injection  drug
delivery systems, the Biojector 2000 system and the Vitajet system and on market
acceptance of other products under  development.  If our products do not achieve
market acceptance,  our business could fail. Currently,  the dominant technology
used for intramuscular and subcutaneous injections is the hollow-needle syringe.
Needle-syringes,  while low in cost, have limitations,  particularly relating to
contaminated  needlestick  injuries.  Use  of  the  Biojector  2000  system  for
intramuscular  and  subcutaneous  injections  eliminates the associated  risk of
these injuries;  however,  the cost per injection is significantly  higher.  The
Biojector 2000, the Vitajet system or any of our products under  development may
be unable to compete successfully with  needle-syringes.  A previous needle-free
injection system  manufactured by us did not achieve market acceptance and is no
longer being  marketed.  The  Biojector  2000 was  introduced  in January  1993.
Failure of the  Biojector  2000  system to gain market  acceptance  would have a
material adverse effect on our financial condition and results of operations.

We have reduced our sales force and may be unable to penetrate  targeted  market
segments. In late fiscal 1998 and early fiscal 1999, we dramatically reduced our
direct product sales force from one national and five district sales managers to
one  national  sales  manager  who is focused on  specifically  targeted  market
segments.  This  reduced  sales  force  may not  have  sufficient  resources  to
adequately  penetrate one or more of the targeted market segments.  Further,  if
the sales force is successful in penetrating  one or more of the targeted market
segments,  we are unable to assure you that our  products  will be  accepted  in
those segments or that product acceptance will result in product revenues which,
together with revenues from corporate  licensing and supply agreements,  will be
sufficient for us to operate profitably.

We may be  unable  to  enter  into  Strategic  Corporate  Licensing  and  Supply
Agreements,  which could cause our  business to suffer.  A key  component of our
sales and marketing strategy is to enter into licensing and supply  arrangements
with leading pharmaceutical and biotechnology companies whose products Bioject's
technology provides either increased medical effectiveness or a higher degree of
market  acceptance.  If we cannot enter into these agreements on terms favorable
to us or at all,  our business may suffer.  In January  1995,  Bioject and Roche
entered  into an  agreement,  whereby the parties  anticipated  that the product
development  phase of the agreement would develop into a supply and distribution
agreement  between Bioject and Roche. In June 1999, Roche advised us that due to
a longer and more costly than expected  regulatory  process to gain clearance to
use the B-2020 in  conjunction  with  Roche's  products,  Roche had  changed its
marketing  strategy.  In making that  change in  marketing  strategy,  Roche was
abandoning  its  exclusive  distribution  rights to the  B-2020 and would not be
seeking a supply of the B-2020 from Bioject.  In July 1998,  Bioject and Merck &
Co. entered into an agreement, whereby the parties anticipated that the


                                       7
<PAGE>

initial  July 1998,  agreement  would lead to a long-term  licensing  and supply
agreement  between the two companies.  In February 1999,  Merck & Co. advised us
that it would not continue,  at the present time, to pursue exclusive license to
or supply of our  products.  Both of these  agreements  resulted in  significant
short-term  revenue.  Neither  agreement  developed  into the long-term  revenue
stream  anticipated by our strategic  partnering  strategy.  We may be unable to
enter into future licensing or supply  agreements with major  pharmaceutical  or
biotechnology  companies.  Even if we enter into these agreements,  they may not
result in sustainable long-term revenues which, when combined with revenues from
product sales, could be sufficient for us to operate profitably.

An important  component of our corporate licensing and supply agreement strategy
is  specifically  targeted  at  entering  into  agreements  of this  nature with
pharmaceutical  and biotechnology  companies  developing  DNA-based vaccines and
medications. The component of the strategy which focuses on companies developing
DNA-based  therapies  arises in great part from  preliminary  data from clinical
studies with animals which  indicates  that use of the Biojector  technology may
result in better performance of some DNA-based  medications than can be achieved
through  the use of  traditional  needle-syringes.  We  cannot  assure  you that
further  clinical  studies will prove  conclusively  that our technology is more
effective in delivering DNA-based  medications than alternative delivery systems
that are either  currently  available  or that may be  developed  in the future.
Further,  should  our  technology  prove  to be  more  effective  in  delivering
DNA-based medications,  we may be unable to gain regulatory clearance to deliver
any DNA-based  medications  using our  products.  Further,  even if  intradermal
delivery of DNA-based  medications  is critical to  effective  delivery of those
compounds,  we may be  unable  to  gain  regulatory  clearance  for  intradermal
delivery of DNA-based medications with our products.  In addition,  there can be
no  assurance  that any company will be  successful  in  developing  one or more
DNA-based  therapies  or  successful  in  bringing  those  therapies  to market.
Further,  should  any  companies  be  successful  in  developing  and  marketing
DNA-based therapies,  we may be unable to enter into long-term license or supply
agreements with any such company,  which could cause our financial condition and
results of operations to suffer.

We may  never  receive  future  royalties  from  the  Blood  Glucose  Monitoring
Technology,  which could cause our financial  condition to suffer.  In May 1999,
rather  than  continue  to fund the cost of its  development,  we  entered  into
negotiations to sell Marathon's blood glucose monitoring technology, and certain
fixed assets related to developing the  technology,  to a third party.  The sale
was  completed  on June 30,  1999.  The terms of the sale of the  blood  glucose
monitoring technology provide for us to receive a royalty on net sales of future
products,  if any,  which  may be  developed  in the  future  from the  licensed
technology.  The  agreement  calls for a royalty  of three  percent of net sales
until we have received total royalty payments of $10 million. The agreement then
calls for  royalty  payments  of one  percent  of net sales  thereafter.  Future
products may never be successfully  developed from the blood glucose  monitoring
technology,  and if  products  are  developed,  they  may  not  be  commercially
successful,  which would mean that we would receive no future royalties and this
could cause our financial condition to suffer.

We have a history of losses and may never be profitable.  Since our formation in
1985, we have incurred  significant  annual  operating  losses and negative cash
flow. At December 31, 1999, we had an  accumulated  deficit of $59 million.  $47
million of the accumulated deficit relates to losses incurred in the needle-free
segment of our  operations.  $12 million of the  accumulated  deficit relates to
losses from our operations to develop the blood glucose  monitoring  technology.
We may never be  profitable,  which  could have a  negative  effect on our stock
price. Historically, our revenues have been derived primarily from licensing and
technology  fees  and  from  limited  product  sales.  The  product  sales  were
principally sales to dealers in order to stock their inventories and to Homecare
Management,  Inc.  More  recently,  we have  sold  our  products  to  end-users,
primarily to public health clinics for vaccinations and to nursing organizations
for flu immunizations. We have not attained profitability at these sales levels.
We may never be able to generate significant revenues or achieve  profitability.
Because  of these  uncertainties  at March  31,  1999,  our  independent  public
accountants qualified their opinion with respect to our ability to continue as a
going concern.

We will need  additional  financing in the future,  and if we cannot  obtain the
necessary  financing  our  business  could  fail.  To date,  our  revenues  from
operations have not been sufficient to meet our cash requirements.  As a result,
since our inception in 1985, we have financed our  operations,  working  capital
needs and capital expenditures  primarily from private placements of securities,
exercises of stock options,  proceeds  received from our initial public offering
in 1986,  proceeds  received from a public  offering of Common Stock in November
1993, licensing and technology revenues,  equity investments from Elan, proceeds
from the sale of the glucose  monitoring  technology  and more recently  through
sales  of  products.  We plan to  fund  our  future  cash  requirements  through
revenues,  debt, and sales of equity  securities.  However,  we may be unable to
obtain the  financing  sufficient  to fund our business  activities on favorable
terms or at all.  Failure  to obtain  adequate  financing  would have a material
adverse impact on our business. In


                                       8
<PAGE>

addition,  sale of our  equity  securities  on  unfavorable  terms  to meet  our
obligations could result in material dilution to the existing shareholders.

We have  outstanding  convertible  preferred  stock,  which is convertible  into
common  stock at prices  which  may be lower  than  market  price at the time of
conversion which could result in dilution to existing common stock holders.  Our
Common  Stock is subject to the  rights  and  preferences  of the Series A and C
Convertible  Preferred Stock, which may be converted into common stock at prices
which  may be  lower  than  market  price  at the  time  of  conversion  causing
substantial  dilution  to  existing  holders  of  common  stock.  The  Series  A
Convertible Preferred Stock is convertible to Common Stock at a conversion price
of $7.50 per share.  The Series C Preferred Stock is convertible to Common Stock
at a  conversion  price of $3.0625  per share.  In  October  2004,  unless it is
converted earlier by the holders or redeemed by us, the shares of Series A and C
Convertible   Preferred   Stock  and  accrued  but  unpaid   dividends   convert
automatically into Common Stock.

We have  limited  manufacturing  experience,  and may be unable to  produce  our
products at the unit costs  necessary for the products to be  competitive in the
market,  which could cause our  financial  condition to suffer.  We have limited
experience manufacturing our products in commercially viable quantities. We have
increased  our  production  capacity  for  the  Biojector  2000  system  through
automation of, and changes in, production  methods,  in order to achieve savings
through  higher  volumes  of  production.  If we are  unable to do so,  then our
results of operations and financial condition could suffer. The current cost per
injection  of the  Biojector  2000 system is  substantially  higher than that of
traditional  needle-syringes,  our principal  competition.  A key element of our
business  strategy  has been to reduce the overall  manufacturing  cost  through
automating production and packaging.  This automation is substantially complete.
There can be no assurance that we will achieve sales and  manufacturing  volumes
necessary to realize cost savings from volume  production at levels necessary to
result in significant unit manufacturing cost reductions.  Failure to do so will
continue  to make  competing  with  needle-syringes  on the  basis of cost  very
difficult  and will  adversely  affect our  financial  condition  and results of
operations.  While we believe that our  experience  manufacturing  the Biojector
enhances the  probability of its success in  manufacturing  the Vitajet or other
devices we may develop, we have had limited experience manufacturing the Vitajet
and  as  of  March  31,  1999,  have  only  recently   completed   installing  a
manufacturing  line to produce  the  Vitajet.  We may be unable to  successfully
manufacture  the  Vitajet  or other  devices  at a unit cost that will allow the
product  to be sold  profitably.  Failure  to do so would  adversely  affect our
financial condition and results of operations.

We are subject to extensive  government  regulation  and must continue to comply
with  these  regulations  or  our  business  could  suffer.   Our  products  and
manufacturing  operations are subject to extensive government regulation in both
the U.S.  and  abroad.  If we cannot  comply with these  regulations,  we may be
unable to distribute  our products,  which could cause our business to suffer or
fail.  In the U.S.,  the  development,  manufacture,  marketing and promotion of
medical devices are regulated by the Food and Drug Administration  ("FDA") under
the  Federal  Food,  Drug,  and  Cosmetic  Act  ("FD&C").  In 1987,  we received
clearance  from the FDA under  Section  510(k) of the FD&C to market a hand-held
CO2-powered  needle-free  injection system. The FD&C provides that new premarket
notifications  under  Section  510(k) of the FD&C are required to be filed when,
among other things,  there is a major change or modification in the intended use
of a device or a change or modification to a legally  marketed device that could
significantly  affect  its safety or  effectiveness.  A device  manufacturer  is
expected  to make the  initial  determination  as to  whether  the change to its
device or its intended use is of a kind that would  necessitate  the filing of a
new 510(k) notification. Although the Biojector 2000 system incorporates changes
from the system with respect to which our 1987 510(k)  marketing  clearance  was
received and expands its intended use, we made the determination that these were
not major changes or modifications in intended use or changes in the device that
could   significantly   affect  the  safety  or  effectiveness  of  the  device.
Accordingly, we further concluded that the 1987 510(k) clearance permitted us to
market the Biojector 2000 system in the U.S. In June 1994, we received clearance
from the FDA under 510(k) to market a version of our Biojector  2000 system in a
configuration targeted at high volume injection  applications.  In October 1996,
we received 510(k) clearance for a needle-free disposable vial access device. In
March 1997, we received additional 510(k) clearance for certain  enhancements to
our Biojector 2000 system.  We currently have an application  pending before the
FDA for 510(k) clearance for  modification to the Vitajet 3 device.  The FDA may
not concur with our  determination  that our current and future  products can be
qualified by means of a 510(k) submission.

Future  changes to  manufacturing  procedures  could  require that we file a new
510(k) notification.  Also, future products, product enhancements or changes, or
changes in product use may require  clearance under Section 510(k),  or they may
require FDA premarket approval ("PMA") or other regulatory clearances.  PMAs and
regulatory clearances other than


                                       9
<PAGE>

510(k)  clearance  generally  involve more  extensive  prefiling  testing than a
510(k)  clearance  and a longer FDA review  process.  Under  current FDA policy,
applications  involving  pre-filled  syringes  would be  evaluated by the FDA as
drugs  rather than  devices,  requiring  FDA new drug  applications  ("NDAS") or
ANDAs.  Depending  on  the  circumstances,  drug  regulation  can be  much  more
extensive and time consuming than device regulation.

FDA regulatory processes are time consuming and expensive.  Product applications
submitted  by us may not be cleared or  approved by the FDA.  In  addition,  our
products must be manufactured in compliance  with Good  Manufacturing  Practices
("GMP")  as  specified  in  regulations  under  the FDA Act.  The FDA has  broad
discretion in enforcing the FDA Act, and noncompliance with the Act could result
in a variety of  regulatory  actions  ranging  from product  detentions,  device
alerts or field corrections, to mandatory recalls, seizures, injunctive actions,
and civil or criminal penalties.

If we  cannot  meet  international  product  standards,  we  will be  unable  to
distribute  our  products  outside of the United  States  which  could cause our
business to suffer.  Distribution  of our products in  countries  other than the
U.S. may be subject to regulation in those  countries.  Failure to satisfy these
regulations would impact our ability to sell our products in these countries and
could cause our business to suffer. In June 1998, we received certification from
TUV Product Services for our quality system, which meets the requirements of ISO
9001 and EN 46001. In June 1999, TUV Product Services audited our quality system
and found that it still meets the requirements of ISO 9001. In November 1999, we
received certification from TUV Product Services for the applicable requirements
of  EC-Directive   93/42/EEC  Annex.   II.3  Medical  Device   Directive.   This
certification  allows us to label our products with the CE Mark and sell them in
the European  Community.  We may be unable to continue to meet the  standards of
ISO 9001 or CE Mark certification.

If  the  healthcare  industry  limits  coverage  or  reimbursement  levels,  the
acceptance of our products could suffer.  The price of our products  exceeds the
price of  needle-syringes  and if coverage or reimbursement  levels are reduced,
market  acceptance of our products could be harmed.  The healthcare  industry is
subject to changing  political,  economic  and  regulatory  influences  that may
affect the procurement practices and operations of healthcare facilities. During
the past several years,  the  healthcare  industry has been subject to increased
government  regulation of reimbursement  rates and capital  expenditures.  Among
other  things,  third party  payers are  increasingly  attempting  to contain or
reduce  healthcare  costs by limiting both coverage and levels of  reimbursement
for healthcare products and procedures.  Because the price of the Biojector 2000
system exceeds the price of needle-syringe, cost control policies of third party
payers,  including government agencies,  may adversely affect acceptance and use
of the Biojector 2000 system.

We are highly  dependent on  third-party  relationships,  and our business could
suffer if we cannot  maintain  these  relationships.  We are  dependent on third
parties  for  distribution  of the  Biojector  2000  system  to  certain  market
segments,  for the manufacture of component  parts,  and for assistance with the
development  and  distribution  of future  application-specific  systems.  If we
cannot  maintain  these  relationships,  or if the third  parties  are unable to
provide the services we require, our business could suffer.

Our current  manufacturing  processes  for the  Biojector  2000 jet injector and
disposable  syringes as well as  manufacturing  processes to produce the Vitajet
consist primarily of assembling  component parts supplied by outside  suppliers.
Some of these components are currently  obtained from single sources,  with some
components  requiring  significant  production  lead times. In the past, we have
experienced  delays in the delivery of certain  components.  To date such delays
have not had a material  adverse  effect on our  operations.  We may  experience
delays in the future,  and these delays could have a material  adverse effect on
our financial condition and results of operations.

In the past, we have entered into agreements  with certain major  pharmaceutical
or  biotechnology  companies for  development  and  distribution  of needle-free
injection  systems  and  for  use  of  our  needle-free   injection  systems  in
conjunction with the pharmaceutical  companies'  products.  In all cases to date
these  companies  have had the right to terminate  those  agreements  at certain
phases as defined in the agreements. In several instances, those agreements have
been terminated before yielding sustained  long-term  licensing or product sales
revenues.  Entering into  agreements of this nature is an important  part of our
overall business strategy. We may be unable to interest any major pharmaceutical
or  biotechnology  companies in entering  into such  agreements.  If  interested
parties are found,  we may be  unsuccessful  at  negotiating  and entering  into
long-term licensing and supply agreements with the interested parties.  Further,
if such  agreements  are  entered  into,  there  can be no  assurance  that  the
companies'  interest and  participation  in the  agreements  and  projects  will
continue and result in long-term,  sustainable  revenues as contemplated by this
aspect of our overall business strategy.  Failure to enter into future licensing
and product supply agreements with major pharmaceutical or


                                       10
<PAGE>

biotechnology  companies  and failure of those  future  agreements  to result in
significant, sustainable long-term revenues could adversely affect our financial
condition.

If we are unable to manage our growth,  our results of operations  could suffer.
If our products  achieve  market  acceptance or if we are successful in entering
into  product  supply  agreements  with major  pharmaceutical  or  biotechnology
companies,  we expect to  experience  rapid  growth.  Such growth would  require
expanded customer service and support, increased personnel, expanded operational
and financial systems, and implementing new and expanded control procedures.  We
may be unable to attract sufficient  qualified  personnel or successfully manage
expanded operations.  As we expand, we may periodically  experience  constraints
that would adversely  affect our ability to satisfy  customer demand in a timely
fashion.  Failure  to manage  growth  effectively  could  adversely  affect  our
financial condition and results of operations.

We may be unable to compete in the medical  equipment  field,  which could cause
our business to fail. The medical  equipment  market is highly  competitive  and
competition  is likely to  intensify.  If we cannot  compete,  our business will
fail. Our products compete primarily with traditional  needle-syringes,  "safety
syringes"  and also with  other  alternative  drug  delivery  systems.  While we
believe our products  provide a superior drug delivery  method,  there can be no
assurance  that we will be able to compete  successfully  with existing or newly
developed drug delivery products.  Many of our competitors have longer operating
histories as well as substantially greater financial,  technical,  marketing and
customer  support  resources.  One or more of these  competitors  may develop an
alternative  drug delivery system that competes more directly with our products,
and our products may be unable to compete successfully with such a product.

We are dependent on a single technology, and if it cannot compete or find market
acceptance,  our  business  will  suffer.  Our  strategy  has been to focus  our
development and marketing efforts on our needle-free injection technology. Focus
on this  single  technology  leaves us  vulnerable  to  competing  products  and
alternative  drug  delivery  systems.  If  our  technology  cannot  find  market
acceptance or cannot compete against other  technologies,  business will suffer.
We  perceive  that  healthcare  providers'  desire  to  minimize  the use of the
traditional   needle-syringe   has  stimulated   development  of  a  variety  of
alternative  drug  delivery  systems such as "safety  syringes,"  jet  injection
systems,  nasal  delivery  systems  and  transdermal  diffusion  "patches".   In
addition,  pharmaceutical companies frequently attempt to develop drugs for oral
delivery instead of injection.  While we believe that for the foreseeable future
there will  continue be a  significant  need for  injections,  alternative  drug
delivery methods may be developed which are preferable to injection.

We rely on patents and proprietary rights to protect our proprietary technology.
We rely on a  combination  of  trade  secrets,  confidentiality  agreements  and
procedures,  and patents to protect our proprietary  technologies.  We have been
granted a number of patents in the United  States and  several  patents in other
countries  covering  certain  technology  embodied in our current jet  injection
system and certain manufacturing  processes.  Additional patent applications are
pending in the U.S. and certain foreign  countries.  The claims contained in any
patent application may not be allowed, or any patent or our patents collectively
will not provide  adequate  protection for our products and  technology.  In the
absence of patent protection, we may be vulnerable to competitors who attempt to
copy our products or gain access to our trade secrets and know-how. In addition,
the laws of foreign  countries  may not protect our  proprietary  rights to this
technology  to the  same  extent  as the  laws of the U.S.  We  believe  we have
independently  developed our  technology and attempt to ensure that our products
do  not  infringe  the  proprietary  rights  of  others.  We  know  of  no  such
infringement claims. However, any claims could have a material adverse affect on
our financial condition and results of operations.

If our products fail or cause harm, we could be subject to  substantial  product
liability,  which  could  cause our  business  to suffer.  Producers  of medical
devices  may face  substantial  liability  for  damages  in the event of product
failure or if it is alleged the  product  caused  harm.  We  currently  maintain
product  liability  insurance and, to date,  have  experienced  only one product
liability claim. There can be no assurance, however, that we will not be subject
to a number of such claims,  that our product  liability  insurance  would cover
such claims,  or that adequate  insurance will continue to be available to us on
acceptable  terms in the future.  Our business  could be  adversely  affected by
product liability claims or by the cost of insuring against such claims.

We are highly  dependent on our key employees,  and our business could suffer if
they were to leave.  Our  success  depends  on the  retention  of our  executive
officers and other key employees. Competition exists for qualified personnel


                                       11

and our success will depend,  in part,  on attracting  and  retaining  qualified
personnel.  Failure in these efforts could have a material adverse effect on our
business, financial condition or results of operations.

There are a large number of shares  eligible for sale into the public  market in
the near  future,  which may reduce the price of our  common  stock.  The market
price of our common  stock could  decline as a result of sales of a large number
of shares of our common stock in the market,  or the perception  that such sales
could occur.  We have a large number of shares of common stock  outstanding  and
available for resale  beginning at various  points in time in the future.  These
sales also might make it more difficult for us to sell equity  securities in the
future  at a time and at a price  that we deem  appropriate.  The  shares of our
common  stock  currently  outstanding  will  become  eligible  for sale  without
registration  pursuant to Rule 144 under the Securities Act,  subject to certain
conditions  of Rule 144.  Certain  holders of our common stock also have certain
demand and piggyback  registration rights enabling them to register their shares
under the Securities Act for sale. We have registered  approximately 2.4 million
shares for resale on Form S-3  registration  statements as well as approximately
1.53 million  shares  issuable upon exercise of warrants.  In addition,  we have
approximately 3.7 million shares of common stock reserved for issuance under our
stock option plan.  As of December 31, 1999,  options to purchase  approximately
580,000 shares of common stock were outstanding and will be eligible for sale in
the public  market  from time to time  subject to vesting.  These stock  options
generally  have  exercise  prices  significantly  below the current price of our
common  stock.  The possible  sale of a  significant  number of these shares may
cause the price of our common stock to fall.

We may be unable to maintain our listing on Nasdaq,  which could cause our stock
price to fall and decrease the liquidity of our common  stock.  Our Common Stock
is quoted on the NASDAQ SmallCap Market. If we cannot comply with the continuing
requirements,  we may be delisted  which could cause the stock price to fall and
decrease the liquidity of our common stock for existing shareholders.  There are
a number of  continuing  requirements  that must be met in order for the  Common
Stock to remain  eligible  for  quotation on the NASDAQ  National  Market or the
NASDAQ  SmallCap  Market.  The failure to meet the  maintenance  criteria in the
future  could result in the  delisting of our Common Stock from NASDAQ.  In such
event, trading, if any, in the Common Stock may then continue to be conducted in
the non- NASDAQ  over-the-counter  market.  As a result, an investor may find it
more difficult to dispose of or to obtain  accurate  quotations as to the market
value of our Common Stock.  In addition,  if the Common Stock were delisted from
trading on NASDAQ and the trading price of the Common Stock were less than $5.00
per share, trading in the Common Stock would also be subject to the requirements
of certain rules  promulgated  under the Exchange Act, which require  additional
disclosure by  broker-dealers  in connection  with any trades  involving a stock
defined as a penny stock. The additional  burdens imposed on broker-dealers  may
discourage  broker-dealers  from effecting  transactions in penny stocks,  which
could  reduce the  liquidity  of the shares of Common  Stock and thereby  have a
material adverse effect on the trading market for the securities.

On April 9,1999,  we were advised by NASDAQ that we were out of compliance  with
the NASDAQ rule that  requires  companies  listed on the  exchange to maintain a
minimum bid price of $1.00 for their stock. On July 9, 1999, the last sale price
of our common stock as reported on the NASDAQ  National  Market System was $0.50
per share. On October 13, 1999, a one-for-five reverse stock split was effected.
At July 15,1999,  29,011,236 shares of Common Stock were outstanding, as well as
options,  warrants  and  convertible  preferred  stock to acquire an  additional
24,378,928 shares of Common Stock. The Reverse Stock Split, decreased the number
of outstanding  shares of Common Stock to  approximately  5.8 million shares and
approximately  4.8 million  shares were  reserved for issuance  upon exercise of
outstanding options, warrants and the conversion of convertible preferred stock.
As of December 31, 1999,  approximately  89.1 million  shares are  available for
future issuances.

Our stock price may be highly  volatile,  which increases the risk of securities
litigation.  The  market for our Common  Stock and for the  securities  of other
early-stage,  small market-capitalization  companies has been highly volatile in
recent years. This increases the risk of securities  litigation relating to such
volatility.  We believe that factors such as quarter-to-quarter  fluctuations in
financial  results,  reduction  in the number of  outstanding  shares due to the
recent reverse stock split, new product  introductions by us or our competition,
public announcements, changing regulatory environments, sales of Common Stock by
certain existing  shareholders,  substantial  product orders and announcement of
licensing  or  product   supply   agreements   with  major   pharmaceutical   or
biotechnology  companies could  contribute to the volatility of the price of our
Common Stock, causing it to fluctuate dramatically. General economic trends such
as recessionary cycles and changing interest rates may also adversely affect the
market price of our Common Stock.

                                 USE OF PROCEEDS

The Shares  offered  hereby are being  registered for the account of the Selling
Shareholders and, accordingly,  we will not receive any of the proceeds from the
sale of the Shares.

                              SELLING SHAREHOLDERS

The Shares being offered for resale by the Selling Shareholders were acquired in
a  private  placement  of our  common  stock to  Amgen  Inc.  The term  "Selling
Shareholder"  includes all persons  acquiring  securities and persons  acquiring
such  securities in permitted  transfers  from the original  holders  thereof in
transactions not requiring registration under the Securities Act.

The following  table sets forth  certain  information  regarding the  beneficial
ownership of shares of Common Stock by the Selling  Shareholders  as of March 1,
2000, and as adjusted to reflect the sale of the Shares.

effective period.

We entered into a development and clinical supply  agreement with Amgen Inc. for
the delivery of Amgen products with our Iject  needle-free  injection system. In
connection  with the  agreement,  Amgen made a $1.5  million  investment  in our
common stock.

                              PLAN OF DISTRIBUTION

We are registering the Shares on behalf of the Selling Shareholders.  As used in
this Prospectus,  the term "Selling  Shareholders"  includes donees and pledgees
selling Shares received from a named Selling  Stockholder after the date of this
Prospectus.  The  Selling  Shareholders  will offer and sell the Shares to which
this Prospectus relates for their own accounts. We will not receive any proceeds
from the  sale of the  Shares.  We will  bear all  costs,  expenses  and fees in
connection  with the  registration  of the  Shares.  Brokerage  commissions  and
similar selling expenses, if any, attributable to the sale of the Shares will be
borne by the Selling Shareholders.

The Selling  Shareholders may offer and sell the Shares from time to time in one
or more types of  transactions  (which may include  block  transactions)  on the
Nasdaq  SmallCap  Market,  in  transactions  directly  with market  makers or in
privately  negotiated  transactions,  through put or call options  transactions,
through  short  sales,  or a  combination  of such  methods  of sale,  at prices
relating to prevailing market prices or at negotiated prices.  Sales may be made
to or through  brokers or dealers  who may receive  compensation  in the form of
discounts,  concessions  or  commissions  from the Selling  Shareholders  or the
purchasers of the Shares. As of the date of this Prospectus, we are not aware of
any agreement, arrangement or understanding between any broker or dealer and the
Selling Shareholders regarding the sale of their Shares, nor are we aware of any
underwriter or  coordinating  broker acting in connection with the proposed sale
of Shares by the Selling  Shareholders.  There is no assurance  that the Selling
Shareholders will sell any or all of the Shares that they offer.

The Selling  Shareholders and any brokers or dealers who participate in the sale
of the  Shares  may be deemed to be  "underwriters"  within  the  meaning of the
Securities Act of 1933, as amended (the  "Securities  Act"), and any commissions
received by them and any profits realized by them on the resale of Shares may be
deemed to be  underwriting  discounts or commissions  under the Securities  Act.
Because the Selling  Shareholders may be deemed to be "underwriters"  within the
meaning of the Securities Act, the Selling  Shareholders  will be subject to the
prospectus  delivery  requirements  of the Securities  Act. We have informed the
Selling  Shareholders  that the  anti-manipulative  provisions  of  Regulation M
promulgated under the Exchange Act may apply to their sales in the market.

The Selling  Shareholders may also resell all or a portion of the Shares in open
market transactions in reliance upon Rule 144 under the Securities Act, provided
it meets the criteria and conforms to the requirements of such Rule.

Upon notification to us by a Selling  Stockholder that any material  arrangement
has been entered  into with a broker or dealer for the sale of Shares  through a
block trade, special offering,  exchange distribution or secondary  distribution
or a purchase by a broker or dealer,  a supplement  to this  Prospectus  will be
filed, if required, pursuant to Rule 424(b) under the Securities Act, disclosing
(i) the name of each such Selling  Stockholder and of the participating  brokers
or dealers,  (ii) the number of Shares  involved,  (iii) the price at which such
Shares were sold, (iv) the commissions paid or discounts or concessions  allowed
to such brokers or dealers,  where applicable,  (v) that such brokers or dealers
did  not  conduct  any  investigation  to  verify  the  information  set  out or
incorporated  by reference in this  Prospectus  and (vi) other facts material to
the transaction.  In addition,  upon notification to us by a Selling Stockholder
that a donee or pledgee  intends to sell more than 500 Shares,  a supplement  to
this Prospectus will be filed.

                                  LEGAL MATTERS

The validity of the issuance of the shares of Common Stock  offered  hereby will
be passed upon for us by Dorsey & Whitney LLP, Seattle, Washington.

The  consolidated  financial  statements   incorporated  by  reference  in  this
Prospectus  and  elsewhere in the  Registration  Statement  have been audited by

ITEM 14. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION.

The following table itemizes the expenses  incurred by the Company in connection
with the shares of Common Stock being  registered.  All of the amounts shown are
estimates except the Securities and Exchange registration fee.

Item                                                               Amount

Securities and Exchange Commission Registration Fee                $  215.00
Blue Sky Fees and Expenses                                              0.00

Total                                                              $6,215.00


The Selling Shareholders will pay no portion of the foregoing expenses.

ITEM 15. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

Generally, Sections 60.387 through 60.414 of the Oregon Business Corporation Act
(the  "Oregon  Act")  authorize a court to award,  or a  corporation's  board of
directors to grant,  indemnification  to directors and officers in circumstances
where the officer or director acted in good faith, in a manner that the director
or officer  reasonably  believed  to be in (or at least not opposed to) the best
interests of the corporation and, if in a criminal  proceeding,  if the director
or officer had no reasonable cause to believe his conduct was unlawful.  Article
IX of the Company's Bylaws provides for  indemnification  to the greatest extent
permitted by the Oregon Act.

Section  60.047 of the Oregon Act authorizes a corporation to limit a director's
liability to the corporation or its shareholders for monetary damages  resulting
from conduct as a director,  except in certain circumstances involving breach of
the  director's  duty  of  loyalty  to  the  corporation  or  its  shareholders,
intentional misconduct or knowing violation of the law, self dealing or approval
of illegal corporate loans or  distributions,  or any transaction from which the
director personally  receives a benefit in money,  property or services to which
the director is not legally entitled.  Article VII of the Company's  Articles of
Incorporation contains provisions  implementing,  to the fullest extent allowed,
limitations on a director's  liability to the Company or its  shareholders.  The
Company currently maintains officers' and directors' liability insurance.

ITEM 17. UNDERTAKINGS.

(a) Rule 415 Offering.

The undersigned Registrant hereby undertakes:

(1) To file,  during  any  period in which  offers or sales  are being  made,  a
post-effective amendment 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 this  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 this
     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 and of the estimated  maximum offering range
     may be  reflected  in the form of  prospectus  filed  with  the  Commission
     pursuant  to Rule  424(b) if, in the  aggregate,  the changes in volume and
     price  represent  no more than 20 percent  change in the maximum  aggregate
     offering price set forth in the "Calculation of Registration  Fee" table in
     the effective registration statement.

(iii)To  include  any  material   information   with  respect  to  the  plan  of
     distribution not previously disclosed in this Registration Statement or any
     material change to such information in this Registration Statement;

provided,  however,  that the undertakings set forth in paragraphs (a)(1)(i) and
(a)(1)(ii)  above do not apply if this  Registration  Statement  is on Form S-3,
Form S-8 or Form F-3,  and the  information  required  to be included in a post-
effective  amendment by those  paragraphs is contained in periodic reports filed
by the  Registrant  pursuant  to Section 13 or Section  15(d) of the  Securities
Exchange Act of 1934 that are  incorporated  by  reference in this  Registration
Statement.

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

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


                                       16
<PAGE>

(b) Filings Incorporating Subsequent Exchange Act Documents by Reference.

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

(h) Indemnification for Liabilities.

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 above, 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 Securities  Act of 1933 and is,  therefore,  unenforceable.  In the event
that a claim  for  indemnification  against  such  liabilities  (other  than the
payment by the Registrant of expense 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
Securities  Act of 1933 and will be governed by the final  adjudication  of such
issue.

government  or  governmental  agency,  department,  or body  that are  currently
necessary for the operation of the business of the Company and its  Subsidiaries

Subsidiaries  owns or possesses  sufficient  rights to use all  patents,  patent

Subsidiary's  rights  in or use of such  Intellectual  Property  has  been or is
currently  threatened to be challenged;  (ii) neither the Company nor any of its

laws and the respective rules and regulations promulgated  thereunder;  and (iv)
the  Investor  will  notify the  Company  promptly  of any change in any of such

of the Company's  representations or warranties or limit the Investor's recourse

acknowledges  that there may  occasionally be times when the Company  determines
that  it  must  suspend  the  use  of  the  Prospectus  forming  a  part  of the
Registration Statement, as set forth in Section 7.2(c).

transactions contemplated herein will have, any right or valid claim against the
Company or the  Investor  for any  commission,  fee or other  compensation  as a

          6.1 Survival of Representations, Warranties, Covenants and Agreements.
Notwithstanding  any  investigation  made by any  party to this  Agreement,  all
covenants,  agreements,  representations  and warranties made by the Company and
the Investor herein shall survive the execution of this Agreement,  the delivery

          6.2 Indemnification.

               (a) The Company hereby covenants and agrees to defend,  indemnify
and save and hold harmless the Investor, together with its officers,  directors,
shareholders,  employees,  attorneys  and  representatives  and each  Person who
controls Investor within the meaning of the Securities Act, from and against any
loss,  cost,  expense,  liability,  claim or legal damages  (including,  without
limitation,  reasonable  fees and  disbursements  of counsel and accountants and
other costs and  expenses  incident  to any actual or  threatened  claim,  suit,
action  or  proceeding,  and all  costs  of  investigation)  (collectively,  the
"Damages")  arising out of or resulting from (i) any inaccuracy in or breach of,
or failure to perform or  observe,  any  representation,  warranty,  covenant or
agreement  made by the Company in this  Agreement  or in any  writing  delivered
pursuant  to this  Agreement  or at the  Closing,  or (ii) any  claims  of third
parties claiming compensation,  commissions or expenses for services as a broker
or finder  based upon  obligations  incurred by the Company.  Damages  resulting
directly from the gross  negligence or willful  misconduct of Investor or any of
its respective

Securities Act of 1933, as amended.  Omitted portions have been filed separately

officers,  directors,  employees or any Person who controls  Investor within the
meaning of the Securities Act are not covered under this Section 6.2(a).

               (b) Investor hereby covenants and agrees to defend, indemnify and
save and hold  harmless  the Company,  together  with its  officers,  directors,
shareholders,  employees,  attorneys  and  representatives  and each  Person who
controls the Company within the meaning of the Securities  Act, from and against
any Damages arising out of or resulting from (i) any inaccuracy in or breach of,
or failure to perform or  observe,  any  representation,  warranty,  covenant or
agreement  made by the  Investor  in this  Agreement  or in any writing or other
agreement  delivered  pursuant  hereto,  or (ii) any  claims  of  third  parties
claiming  compensation,  commissions  or  expenses  for  services as a broker or
finder  based upon  obligations  incurred  by the  Investor.  Damages  resulting
directly from the gross  negligence or willful  misconduct of the Company or any
of its respective officers, directors,  employees or any Person who controls the
Company  within the meaning of the  Securities  Act are not  covered  under this
Section 6.2(b).

               (c) Each party  entitled  to be  indemnified  pursuant to Section
6.2(a) or 6.2(b)  (each,  an  "Indemnified  Party") shall notify the other party
(the  "Indemnifying  Party") in writing of any action  against such  Indemnified
Party in  respect  of which the  Indemnifying  Party is or may be  obligated  to
provide  indemnification on account of Section 6.2(a) or 6.2(b),  promptly after
the receipt of notice or knowledge of the commencement  thereof. The omission of
any  Indemnified  Party so to notify the  Indemnifying  Party of any such action
shall not relieve the Indemnifying Party from any liability which it may have to
such Indemnified  Party except to the extent the  Indemnifying  Party shall have
been  materially  prejudiced  by the  omission of such  Indemnified  Party so to
notify it,  pursuant to this  Section  6.2(c).  In case any such action shall be
brought against any Indemnified Party and it shall notify the Indemnifying Party
of the commencement  thereof, the Indemnifying Party shall be entitled to assume
the defense thereof,  with counsel  reasonable  satisfactory to such Indemnified
Party, and after notice from it to such Indemnified  Party of its election so to
assume the defense thereof,  the  Indemnifying  Party will not be liable to such
Indemnified  Party under Section 6.2(a) or 6.2(b) for any legal or other expense
subsequently  incurred by such Indemnified  Party in connection with the defense
thereof nor for any settlement  thereof  entered into without the consent of the
Indemnifying Party; provided,  however, that (i) if the Indemnifying Party shall
elect  not to  assume  the  defense  of  such  claim  or  action  or (ii) if the
Indemnified Party reasonably determines (x) that there may be a conflict between
the  positions  of  the  Indemnifying  Party  and of the  Indemnified  Party  in
defending such claim or action or (y) that there may be legal defenses available
to such  Indemnified  Party  different from or in addition to those available to
the Indemnifying Party, then separate counsel for the Indemnified Party shall be
entitled  to  participate  in and conduct  the  defense,  in the case of (i) and
(ii)(x),  or  such  different  defenses,   in  the  case  of  (ii)(y),  and  the
Indemnifying  Party shall be liable for any  reasonable  legal or other expenses
incurred by the Indemnified Party in connection with the defense.

               (d) Neither the Indemnified Party nor the Indemnifying  Party may
concede,  settle or compromise any action contemplated by Section 6.2(c) without
the consent of the other party, which consent will not be unreasonably  withheld
or  delayed in light of all  factors  of  importance  to such  party;  provided,
however,  that if the Indemnified  Party shall fail to consent to the settlement
of any action where (i) such settlement includes an unconditional release of all
actions

***Confidential  treatment  has  been  requested  pursuant  to  Rule  406 of the
Securities Act of 1933, as amended.  Omitted portions have been filed separately

<PAGE>

against  the  Indemnified  Party  and  requires  no  payment  on the part of the
Indemnified  Party to the claimant or any other party, (ii) such settlement does
not require any action on the part of the Indemnified  Party and does not impose
terms restricting or adversely affecting the Indemnified  Party's activity,  and
(iii)  the  claimant  has  affirmatively  indicated  that  it will  accept  such
settlement,  then the Indemnifying Party shall have no liability with respect to
any  payment  to be made in  respect  of such  action in excess of the  proposed
settlement amount.

               (e) The foregoing indemnification  provisions are in addition to,
and not in derogation  of, any  statutory,  equitable or  common-law  remedy any
party may have for breach of representation, warranty, covenant or agreement, or
otherwise.

          6.3  Injunctive  Relief.  (a) Any  party  may  bring  a claim  seeking
specific  performance  by way of  injunctive  relief before a court of competent
jurisdiction  in accordance  with Section 9.3 to enforce the  provisions of this
Agreement,  and (b) in the event of any breach by either party of Section  9.10,
the  other  party  may  seek  injunctive   relief  from  a  court  of  competent
jurisdiction to restrain any such breach.

          6.4 No Implied Waiver. Except as expressly provided in this Agreement,
no course of dealing between the Company and Investor and no delay in exercising
any such right, power or remedy conferred hereby or now or hereafter existing at
law in  equity,  by  statute  or  otherwise,  shall  operate  as a waiver of, or
otherwise prejudice, any such right, power or remedy.

     7. Registration of the Shares; Compliance with the Securities Act.

          7.1 Registration Procedures and Expenses. The Company shall:

               (a) use its  efforts  to  prepare  and file with the SEC,  within

"Registration  Statement")  to enable the  resale of the Shares by the  Investor
from time to time through the automated quotation system of the Nasdaq Small Cap

               (b) use its best efforts to cause the  Registration  Statement to

               (c) use its best  efforts to  prepare  and file with the SEC such
amendments and supplements to the Registration Statement and any prospectus used
in  connection  therewith  (a  "Prospectus")  as may be  necessary  to keep  the
Registration  Statement  current and effective for a period not exceeding,  with
respect to the Shares,  the earlier of (i) the second anniversary of the Closing
Date,  (ii) the date on which the  Investor may sell all Shares then held by the
Investor  without  restriction  by the volume  limitations of Rule 144(e) of the
Securities  Act, or (iii) such time as all Shares have been sold pursuant to the
Registration Statement;

               (d) furnish to the Investor with respect to the Shares registered

public sale or other Disposition of all or any of the Shares by the Investor;

               (e) file documents required of the Company for blue sky clearance
in states  specified in writing by the  Investor;  provided,  however,  that the
Company shall not be required to qualify to do business or consent to service of
process in any  jurisdiction  in which it is not now so  qualified or has not so
consented;

               (f) bear all  expenses  in  connection  with  the  procedures  in
paragraph (a) through (e) of this Section 7.1 and the registration of the Shares
pursuant to the Registration Statement; and

               (g) advise the Investor,  promptly  after it shall receive notice
or obtain  knowledge  of the  issuance of any stop order by the SEC  delaying or
suspending the effectiveness of the Registration  Statement or of the initiation
or threat of any proceeding for that purpose;  and it will promptly use its best
efforts to prevent the issuance of any stop order or to obtain its withdrawal at
the earliest possible moment if such stop order should be issued.

          The  Company   understands  that  the  Investor   disclaims  being  an
underwriter,  but the Investor  being deemed an underwriter by the SEC shall not
relieve the Company of any obligations it has hereunder;  provided, however that
if the Company receives notification from the SEC that the Investor is deemed an
underwriter,  then the ninety day period  provided  in Section  7.1(b)  shall be
extended to the earlier of (i) the *** (***) day after such SEC notification, or
(ii) *** (***) days after the initial filing of the Registration  Statement with
the SEC.

          7.2 Transfer of Shares After Registration; Suspension.

               (a) The  Investor  agrees  that  it will  not  effect  any  sale,
assignment  or other  transfer (a  "Disposition")  of the Shares or its right to
purchase  the Shares  that would  constitute  a sale  within the  meaning of the
Securities Act except as contemplated in the Registration  Statement referred to
in Section 7.1 and as  described  below,  and that it will  promptly  notify the
Company  of any  changes  in  the  information  set  forth  in the  Registration
Statement regarding the Investor or its plan of distribution.

Company  shall (i) if deemed  necessary by the  Investor,  prepare and file from
time to  time  with  the  SEC a  post-effective  amendment  to the  Registration
Statement or a supplement to the related Prospectus or a supplement or amendment
to any document  incorporated  therein by  reference or file any other  required
document  (A) so that such  Registration  Statement  will not  contain an 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 not misleading,  and
so that,  as  thereafter  delivered  to  purchasers  of the  Shares  being  sold
thereunder,  such Prospectus will not contain an 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 under which they
were made, not misleading or (B) to revise or amend the plan of  distribution of
the Shares as requested by Investor; (ii) provide the Investor copies of any

documents  filed pursuant to Section  7.2(b)(i);  and (iii) inform each Investor
that the Company has complied  with its  obligations  in Section  7.2(b)(i)  (or
that, if the Company has filed a  post-effective  amendment to the  Registration
Statement which has not yet been declared effective, the Company will notify the
Investor  to that  effect,  will  use  its  reasonable  efforts  to  secure  the
effectiveness of such post-effective  amendment as promptly as possible and will
promptly  notify the  Investor  pursuant  to Section  7.2(b)(i)  hereof when the
amendment has become effective).

               (c)  Subject  to  paragraph  (d)  below,  in the event (i) of any
request by the SEC or any other federal or state  governmental  authority during
the period of  effectiveness  of the  Registration  Statement for  amendments or
supplements to a Registration  Statement or related Prospectus or for additional
information;  (ii) of the  issuance  by the SEC or any  other  federal  or state
governmental  authority  of any stop order  suspending  the  effectiveness  of a
Registration  Statement or the initiation of any  proceedings  for that purpose;
(iii) of the  receipt by the  Company of any  notification  with  respect to the
suspension of the  qualification  or exemption from  qualification of any of the
Shares for sale in any  jurisdiction  or the  initiation or  threatening  of any
proceeding for such purpose;  or (iv) of any event or circumstance  which,  upon
the  advice  of its  counsel,  necessitates  the  making of any  changes  in the
Registration Statement or Prospectus,  or any document incorporated or deemed to

Statement,  it will not contain any untrue  statement of a material  fact or any

Prospectus,  it will not contain any untrue  statement of a material fact or any

writing to the Investor (the "Suspension Notice") to the effect of the foregoing
and,  upon receipt of such  Suspension  Notice,  the Investor  will refrain from
selling any Shares pursuant to the Registration Statement (a "Suspension") until
the  Investor's  receipt  of  copies of a  supplemented  or  amended  Prospectus
prepared  and filed by the  Company,  or until it is  advised  in writing by the
Company that the current  Prospectus may be used, and has received copies of any
additional or supplemental  filings that are incorporated or deemed incorporated
by reference in any such Prospectus. In the event of any Suspension, the Company
will use its best efforts to cause the use of the  Prospectus so suspended to be
resumed as soon as  reasonably  practicable,  and in any event not more than ***
(***) days after the delivery of a Suspension Notice to the Investor;  provided,
however,  that  the  Company  shall  not be  required  to  amend a  Registration
Statement or supplement a Prospectus  for a period of up to *** (***) days after
delivery  of a  Suspension  Notice to the  Investor  if the  Company's  Board of
Directors determines in good faith that do so would be seriously  detrimental to

Prospectus to the  transferee of such Shares or sells the Shares  pursuant to an
exemption  under the  Securities  Act. Upon receipt of a request  therefor,  the
Company  agrees to provide an  adequate  number of current  Prospectuses  to the
Investor and to supply copies to any other parties requiring such Prospectuses.

          7.3 Indemnification. For the purpose of this Section 7.3:

          (i) the term "Selling  Stockholder" shall include the Investor and any
Person  controlling,  controlled  by or under common  control with  Investor (an
"Affiliate");

          (ii)  the  term  "Registration  Statement"  shall  include  any  final
Prospectus,  exhibit,  supplement  or  amendment  included in or relating to the
Registration Statement referred to in Section 7.1; and

          (iii) the term "untrue  statement"  shall include any untrue statement
or alleged untrue statement, or any omission or alleged omission to state in the
Registration  Statement  a  material  fact  required  to be  stated  therein  or
necessary  to make the  statements  therein,  in the light of the  circumstances
under which they were made, not misleading.

               (a) The  Company  agrees  to  indemnify  and hold  harmless  each
Selling Stockholder from and against any losses,  claims, damages or liabilities
to which such Selling  Stockholder  may become subject (under the Securities Act
or otherwise) insofar as such losses, claims, damages or liabilities (or actions
or  proceedings  in  respect  thereof)  arise out of, or are based  upon (i) any
untrue statement of a material fact contained in the Registration  Statement, or
(ii) any  failure by the  Company to fulfill  any  undertaking  included  in the
Registration Statement,  and the Company will reimburse such Selling Stockholder
for any reasonable legal or other expenses reasonably incurred in investigating,
defending  or  preparing  to defend any such  action,  proceeding  or claim,  or
preparing to defend any such action,  proceeding  or claim;  provided,  however,
that the  Company  shall not be liable in any such case to the extent  that such
loss,  claim,  damage or  liability  arises out of, or is based upon,  an untrue
statement  made in such  Registration  Statement in reliance  upon and in strict
conformity with written information  furnished to the Company by or on behalf of
such Selling Stockholder specifically for use in preparation of the Registration
Statement.

               (b) The  Investor  agrees  to  indemnify  and hold  harmless  the
Company (and each person, if any, who controls the Company within the meaning of
Section 15 of the  Securities  Act,  each  officer of the  Company who signs the
Registration  Statement  and each  director of the Company) from and against any
losses,  claims,  damages  or  liabilities  to which  the  Company  (or any such
officer,   director  or  controlling  person)  may  become  subject  (under  the
Securities  Act or  otherwise),  insofar  as such  losses,  claims,  damages  or
liabilities (or actions or proceedings in respect  thereof) arise out of, or are
based  upon,  any  untrue   statement  of  a  material  fact  contained  in  the
Registration Statement if such untrue statement was made in reliance upon and in
strict  conformity  with  written  information  furnished by or on behalf of the
Investor specifically for use in preparation of the Registration Statement,  and
the  Investor  will  reimburse  the  Company  (or  such  officer,   director  or
controlling  person),  as the case  may be,  for any  legal  or  other  expenses
reasonably incurred in investigating,  defending or preparing to defend any such
action, proceeding or claim; provided that

***Confidential  treatment  has  been  requested  pursuant  to  Rule  406 of the
Securities Act of 1933, as amended.  Omitted portions have been filed separately
with the Securities and Exchange Commission.
<PAGE>


the  Investor's  obligation to indemnify the Company shall be limited to the net
amount received by the Investor from the sale of the Shares sold by the Investor
pursuant to the Registration Statement.

               (c) Promptly after receipt by any indemnified  person of a notice
of a claim or the beginning of any action in respect of which indemnity is to be
sought  against an  indemnifying  person  pursuant  to this  Section  7.3,  such
indemnified person shall notify the indemnifying person in writing of such claim
or of the  commencement  of such  action,  but the  omission  to so  notify  the
indemnifying  party will not relieve it from any liability  which it may have to
any  indemnified  party  under this  Section 7.3 (except to the extent that such
omission  materially and adversely  affects the indemnifying  party's ability to
defend such action) or from any liability otherwise than under this Section 7.3.
Subject to the provisions  hereinafter  stated, in case any such action shall be
brought against an indemnified person, the indemnifying person shall be entitled
to participate therein, and, to the extent that it shall elect by written notice
delivered to the indemnified party promptly after receiving the aforesaid notice
from such  indemnified  party,  shall be entitled to assume the defense thereof,
with counsel reasonably  satisfactory to such indemnified  person.  After notice
from the  indemnifying  person to such  indemnified  person of its  election  to
assume the defense thereof, such indemnifying person shall not be liable to such
indemnified  person  for  any  legal  expenses  subsequently  incurred  by  such
indemnified  person in connection with the defense thereof;  provided,  however,
that if there  exists or shall exist a conflict  of interest  that would make it
inappropriate, in the opinion of counsel to the indemnified person, for the same
counsel to represent both the indemnified person and such indemnifying person or
any affiliate or associate thereof,  the indemnified person shall be entitled to
retain its own counsel at the expense of such indemnifying person, so long as no
indemnifying  person is  responsible  for the fees and expenses of more than one
separate counsel for all indemnified parties. In no event shall any indemnifying
person be liable in  respect of any  amounts  paid in  settlement  of any action
unless the indemnifying person shall have approved the terms of such settlement;
provided that such consent shall not be unreasonably  withheld.  No indemnifying
person  shall,  without the prior  written  consent of the  indemnified  person,
effect any  settlement  of any pending or  threatened  proceeding  in respect of
which any indemnified  person is or could have been a party and  indemnification
could  have been  sought  hereunder  by such  indemnified  person,  unless  such
settlement includes an unconditional release of such indemnified person from all
liability on claims that are the subject matter of such proceeding.

               (d) If the  indemnification  provided  for in this Section 7.3 is
unavailable  to or  insufficient  to hold  harmless an  indemnified  party under
subsection  (a) or (b)  above in  respect  of any  losses,  claims,  damages  or
liabilities (or actions or proceedings in respect thereof)  referred to therein,
then each  indemnifying  party shall contribute to the amount paid or payable by
such  indemnified  party  as  a  result  of  such  losses,  claims,  damages  or
liabilities (or actions in respect thereof) in such proportion as is appropriate
to reflect the relative fault of the Company on the one hand and the Investor on
the other in connection  with the statements or omissions or other matters which
resulted in such losses,  claims,  damages or liabilities (or actions in respect
thereof), as well as any other relevant equitable  considerations.  The relative
fault shall be determined by reference to, among other things, in the case of an
untrue statement,  whether the untrue statement relates to information  supplied
by the  Company on the one hand or the  Investor  on the other and the  parties'
relative intent, knowledge,  access to information and opportunity to correct or
prevent  such untrue  statement.  The amount  paid or payable by an  indemnified
party as a result of the losses, claims,

Securities Act of 1933, as amended.  Omitted portions have been filed separately

<PAGE>

damages or liabilities (or actions in respect thereof) referred to above in this
subsection (d) shall be deemed to include any legal or other expenses reasonably
incurred by such indemnified party in connection with investigating or defending
any such action or claim. Notwithstanding the provisions of this subsection (d),
the  Investor  shall not be required to  contribute  any amount in excess of the
amount by which the net amount  received  by the  Investor  from the sale of the
Shares to which such loss  relates  exceeds the amount of any damages  which the
Investor has otherwise been required to pay by reason of such untrue  statement.
No person guilty of fraudulent  misrepresentation (within the meaning of Section
11(f) of the Securities Act) shall be entitled to  contribution  from any person
who was not guilty of such fraudulent misrepresentation.

               (e) The parties to this Agreement  hereby  acknowledge  that they
are  sophisticated  business  persons who were represented by counsel during the
negotiations regarding the provisions hereof including,  without limitation, the
provisions  of  this  Section  7.3,  and  are  fully  informed   regarding  said
provisions.  They further  acknowledge  that the  provisions of this Section 7.3
fairly  allocate the risks in light of the ability of the parties to investigate
the Company and its business in order to assure that adequate disclosure is made
in the  Registration  Statement as required by the Act and the Exchange Act. The
parties are advised that federal or state public  policy as  interpreted  by the
courts in certain  jurisdictions may be contrary to certain of the provisions of
this Section 7.3, and the parties hereto hereby  expressly  waive and relinquish
any right or ability to assert such public  policy as a defense to a claim under
this Section 7.3 and further agree not to attempt to assert any such defense.

          7.4  Termination  of  Conditions  and   Obligations.   The  conditions
precedent imposed by Section 5 or this Section 7 upon the transferability of the
Shares shall cease and terminate as to any particular  number of the Shares when
such  Shares  shall  have  been  effectively  registered  for  resale  under the
Securities Act and sold or otherwise disposed of in accordance with the intended
method of  Disposition  set forth in the  Registration  Statement  covering such
Shares or at such time as an opinion of counsel  satisfactory  to the Company in
its  reasonable  judgment  shall  have been  rendered  to the  effect  that such
conditions are not necessary in order to comply with the Securities Act.

          7.5 Information  Available.  So long as the Registration  Statement is
effective covering the resale of Shares owned by the Investor,  the Company will
furnish to the Investor:

               (a) as soon as practicable after it is available, one copy of (i)

of certified public accountants),  (ii) its Annual Report on Form 10-K and (iii)
its  Quarterly  Reports on Form 10-Q (the  foregoing,  in each  case,  including
exhibits); and

               (b) an adequate number of copies of the Prospectuses to supply to
any  other  party  requiring  such  Prospectuses;  and  the  Company,  upon  the
reasonable  request  of  the  Investor,   will  meet  with  the  Investor  or  a
representative  thereof at the Company's headquarters to discuss all information
relevant for disclosure in the Registration Statement covering the Shares and

without the prior  approval  of such press  release or  disclosure  by the other
party hereto.

          9.11 Required Disclosure.  If in the reasonable opinion of any party's
counsel (which may include such party's internal counsel), a disclosure which is
subject to Section  9.10 shall be required by law,  regulation  or court  order,
including without  limitation in a filing with the SEC or the United States Food
and Drug  Administration,  then the disclosing party shall provide copies of the
disclosure  reasonably  in advance of such  filing or other  disclosure  for the
nondisclosing  party's  prior review and comment,  and the  nondisclosing  party

Gentlemen and Ladies:

We are delivering this opinion in connection with the Registration  Statement on
Form S-3 (the  "Registration  Statement") of Bioject Medical  Technologies  Inc.
(the  "Company") to be filed with the Securities and Exchange  Commission  under
the Securities Act of 1933, as amended (the "Securities  Act"),  with respect to
an aggregate of 65,796 shares, without par value, of common stock of the Company
(the "Shares") to be resold by certain selling  shareholders  named therein (the
"Selling Shareholders").

We have  examined  and are  familiar  with  originals  or copies,  certified  or
otherwise identified to our satisfaction,  of such documents,  corporate records
and other  instruments  relating to the  incorporation of the Company and to the
authorization and issuance of the Shares,  and have made such  investigations of
law, as we have deemed necessary and advisable.

Based upon the  foregoing  and having due regard for such legal  questions as we
have deemed relevant, we are of the opinion that:

     The 65,796 Shares, which were purchased by The Selling  Shareholders,  have
     been duly authorized, and, when issued, constituted or will constitute duly
     authorized,  legally issued,  fully paid and nonassessable shares of common
     stock of the Company.

We  hereby  consent  to  the  filing  of  this  opinion  as an  exhibit  to  the
Registration  Statement  referred to above,  and to the reference to our firm in
the Prospectus constituting a part of the Registration Statement.


                                        Very truly yours,


                                        /s/DORSEY & WHITNEY LLP




                                                                    EXHIBIT 23.2

                    CONSENT OF INDEPENDENT PUBLIC ACCOUNTANTS

As independent  public  accountants,  we hereby consent to the  incorporation by
reference  in this Form S-3  Registration  Statement  of our report dated May 7,
1999 included in the Bioject  Medical  Technologies,  Inc. Annual Report on Form
10-K for the fiscal year ended March 31, 1999 and to all  references to our firm
included in this Registration Statement.
