GENERAL

Bioject  Medical  Technologies  Inc.  ("Bioject"  or  the  "Company")  develops,
manufactures  and markets a jet injection  system for needle-free drug delivery.
Using this technology to administer  injections virtually eliminates the risk of
contaminated   needlestick   injuries  and  resulting   blood-  borne   pathogen
transmission,  a major concern throughout the healthcare  industry.  The Company
manufactures and markets a professional jet injection  system,  the Biojector(R)
2000, which allows healthcare  professionals to inject  medications  through the
skin, both  intramuscularly and subcutaneously,  without a needle. The Biojector
2000 system consists of two components: a hand-held,  reusable jet-injector (the
"Biojector 2000");  and a sterile,  single-use  disposable  syringe  ("Biojector
syringe").  The  system  is  capable  of  delivering  variable-dose  needle-free
injections up to 1 ml.  Additionally,  the Company has developed and is awaiting
regulatory  clearance  to begin  selling  the  B4000  jet-injection  system  for
self-delivery of various  medications up to 1 ml. for use by  non-professionals.
The Company is also developing systems for Hoffmann-La Roche to use with certain
of their products pursuant to an agreement signed January 10, 1995. On March 23,
1998 the Company entered into a transaction with Vitajet Corporation ("Vitajet")
whereby the Company acquired, along with certain other assets, the rights to the
Vitajet(R),   a  spring-powered   self-injection   device  which  currently  has
regulatory clearance for administering  injections of insulin. See "Research and
Product  Development".  In  October  1997,  the  Company  entered  into a  joint
development  agreement  with Elan  Corporation,  plc ("Elan") for the license of
certain blood glucose  monitoring  technology  from Elan and the development and
commercialization  of  that  technology  by a  newly  formed  subsidiary  of the
Company. See "Research and Product  Development." The Company intends to operate
as two distinct  business  segments:  the  jet-injection  business and the blood
glucose monitoring business.

Needle-Free Injection Business.

Currently, medications are administered using various methods, each of which has
advantages and limitations.  The leading drug delivery  techniques  include oral
ingestion,  intravenous  infusion,  subcutaneous  and  intramuscular  injection,
inhalation and transdermal diffusion "patch." Many drugs are effective only when
administered  by  injection.  Published  data  indicates  more than 1.7  billion
needle-syringes   sold   annually  in  the  U.S.  The  Company   believes   that
approximately  80% of these syringes are used for  subcutaneous or intramuscular
injections up to 1 ml.

Injections  using  traditional  needle-syringes  suffer  from many  shortcomings
including (i) the risk of needlestick  injuries,  (ii) the risk of penetrating a
patient's vein and (iii) patients' aversion to needles and discomfort.  The most
important of these, the contaminated  needlestick  injury,  occurs when a needle
that has been exposed to a patient's blood accidentally  penetrates a healthcare
worker's skin.  Contaminated  needles can transmit deadly blood-borne  pathogens
including  such viruses as HIV and  hepatitis B.  Published  data  estimates the
total number of reported needlestick injuries in the U.S. at between 370,000 and
800,000 annually.

In  recent  years,   with  the  growing   awareness  of   blood-borne   pathogen
transmission,  safety has become a critical concern for hospitals and healthcare
professionals  as well as patients.  As a result,  pressures  on the  healthcare
industry  to  eliminate  the  risk of  contaminated  needlestick  injuries  have
increased.  For example, the U.S.  Occupational Safety and Health Administration
("OSHA")  issued  regulations,  effective  in  1992,  which  require  healthcare
institutions  to treat  all blood and other  body  fluids as  infectious.  These
regulations  require  the  implementation  of  "engineering  and  work  practice
controls"  to  "isolate  or remove the  blood-borne  pathogens  hazard  from the

<PAGE>

workplace."  Among the required  controls  are special  handling and disposal of
contaminated  "sharps" in biohazardous "sharps" containers and follow-up testing
for  victims of  needlestick  injuries.  These  regulations  have  significantly
increased the cost of using needle-syringes.

The costs  resulting  from  needlestick  injuries  vary  widely.  Uncontaminated
needlesticks  involve relatively little cost, while  investigating and following
up  contaminated  needlestick  injuries are much more  expensive.  Investigation
typically includes  identifying the source of contamination,  testing the source
for blood-borne  pathogens and repeatedly testing the needlestick victim over an
extended period. Some healthcare  providers are requiring  additional  measures,
including presuming that all needlestick  injuries involve  contaminated needles
unless  proven  otherwise  and,  under  certain   circumstances,   administering
prophylactic  treatment  such as  zidovudine  (AZT) or other  drugs.  The  costs
associated  with  treating  needlestick  injuries  that result in  infection  by
life-threatening pathogens, such as HIV or hepatitis B, are dramatically higher.
In an effort to protect  healthcare  workers  from  needlestick  injuries,  many
healthcare facilities have adopted more expensive, alternative technologies. One
such  technology  is an  intravenous  ("IV") port that permits the  injection of
medication directly into the IV line without requiring the use of a sharp needle
for each administration. Another is the "safety syringe," generally a disposable
needle-syringe  with a plastic  sheath  mechanism  intended  to cover the needle
after use. Despite many efforts to reduce the risk of needlestick injuries, such
injuries remain a major health concern.

The Company's  long-term goal is to establish its needle-free  injection systems
as the  preferred  drug  delivery  method for all  medications  administered  by
intramuscular  or  subcutaneous  injection.  The Company  currently  markets the
Biojector  2000  system to  public  health  and flu  immunization  clinics,  has
developed and is awaiting regulatory  clearance of a gas-powered  self-injection
device for the
delivery of various medications by  non-professionals  in the home. In addition,
through a  transaction  with Vitajet  Corporation,  the Company has acquired the
Vitajet    spring-powered    self-injection    system,    and   is    developing
application-specific devices to be marketed by Hoffmann-La Roche. The Company is
also seeking  relationships with  pharmaceutical and biotechnology  companies to
market its Biojector 2000 and self injector  products for specific  applications
and to develop other application-specific devices and companion syringes.

Blood Glucose Monitoring Business.

Diabetes  mellitus  is a disorder of  carbohydrate  metabolism  that  affects an
estimated 16.5 million Americans and 125 million people worldwide,  half of whom
remain undiagnosed.  Insulin facilitates the uptake of circulating blood glucose
into tissues, a fundamental process of metabolism.  A lack of, or resistance to,
the hormone insulin characterizes the disease.  Incidence of the disease,  which
can originate from many factors, is rising, particularly in developing countries
as non-Caucasian populations begin to adopt western diet and culture.

Type I diabetics are individuals dependent on external administration of insulin
who must  frequently  measure their blood  glucose  level and,  depending on the
results,  administer injections of insulin or consume a carbohydrate-rich snack.
Fluctuation of a person's blood glucose level outside a normal range,  which may
occur in the time interval between measurements frequently causes serious health
complications and even death. Using currently available blood glucose monitoring
systems to check their blood glucose level,  diabetic  patients must lance their
finger with a disposable lancet,  draw a drop of blood, and place the blood on a
reagent  strip which is then read by an  electronic  reader  which  displays the
results.  Many patients find this procedure painful and  inconvenient,  and as a
result,  many  diabetics  do not measure  their blood  glucose  with  sufficient
frequency.

The  Company  has  licensed  and  intends to develop a  convenient,  easy to use
continuous blood glucose monitoring system which will permit diabetics to better
monitor  and,  thereby,  better  regulate  their blood  glucose  levels so as to
diminish or eliminate the long-term complications of this disorder.

THE COMPANY

The  Company's  needle-free  jet injection  operations  are conducted by Bioject
Inc.,  an Oregon  corporation,  which is a wholly  owned  subsidiary  of Bioject
Medical  Technologies Inc., an Oregon  corporation.  The Company's blood glucose
monitoring system development operations are conducted by a subsidiary,  Bioject
JV Subsidiary Inc., an Oregon corporation.

<PAGE>

Although  Bioject Inc.  commenced  operations in 1985, the Company 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 in order to  establish a U.S.  domestic
corporation  as the publicly  traded parent company for Bioject Inc. and Bioject
Medical Systems Ltd. Bioject Medical Systems Ltd. was terminated in fiscal 1997.
Bioject JV  Subsidiary  Inc. ("JV or JV Sub") was formed in October 1997 for the
purpose  of  developing  and   commercializing   the  blood  glucose  monitoring
technology.  All  references  to  the  Company  herein  are to  Bioject  Medical
Technologies Inc. and its subsidiaries,  unless the context requires  otherwise.
The Company's executive offices and operations are located at 7620 SW Bridgeport
Road, Portland, Oregon 97224, and its telephone number is (503) 639-7221.

DESCRIPTION OF THE COMPANY'S PRODUCTS

Needle-free Injection Business.

The Company's current product, the Biojector 2000 system, is a refinement of jet
injection  technology that enables healthcare  professionals to reliably deliver
measured variable doses of medication  through the skin, either  intramuscularly
or subcutaneously,  without a needle.  Giving an injection with a Biojector 2000
system  is easy  and  straightforward.  The  healthcare  worker  checks  the CO2
pressure on the easy-to-read gauge at the rear of the injector, draws medication
up into a  disposable  plastic  syringe,  inserts  the  syringe  into the  power
injector, presses the syringe tip against the appropriate disinfected surface on
the  patient's  skin,  and  then  presses  an  actuator  thereby  injecting  the
medication.  Medication is expelled  rapidly through a precision  molded,  small
diameter orifice in a thin stream at a velocity sufficient to penetrate the skin
and force the  medication  into the tissue at the desired  level.  The Biojector
2000 system consists of two components: a hand-held,  reusable jet injector; and
a sterile, single-use, disposable plastic syringe capable of delivering variable
doses of medication up to 1 ml.

The first component,  the Biojector 2000, is a portable  hand-held unit which is
approximately  the size of a  flashlight  and is  designed  both for easy use by
healthcare  professionals,  as well as to be attractive and  non-threatening  to
patients. As described in the June 7, 1993 issue of BUSINESSWEEK,  the Biojector
2000 won the 1993 Gold Industrial  Design  Excellence  Award given by Industrial
Designers  Society of  America  for its  aesthetically  pleasing  and  ergonomic
design.  In July  1994,  the  Biojector  2000  also  received  the  Alliance  of
Children's  Hospitals  Seal  of  Approval.  The  Biojector  2000  injector  uses
disposable  CO2  cartridges as a power  source.  The CO2  cartridges,  which are
purchased  by the  Company  from an  outside  supplier,  give an  average of ten
injections  before  requiring  replacement.  The  CO2 gas  provides  consistent,
reliable pressure on the plunger of the disposable  syringe,  thereby propelling
the medication  into the tissue.  The CO2 propellant  does not come into contact
with either the patient or the medication.

The second component,  the Biojector single-use  disposable syringe, is provided
in a  sterile,  peel-open  package  and  consists  of a plastic,  needle-  free,
variable dose syringe containing a plunger,  accompanied by a disposable plastic
vial adapter which is used to fill the syringe. (If requested by a customer, the
product can also be supplied  with a needle which is used as an  alternative  to
the  vial  adapter  for  filling  the  syringe.)  The  body  of the  syringe  is
transparent and has graduated markings to aid filling by healthcare workers.

There are five  different  Biojector  syringes,  each of which is intended for a
different  injection  depth or body type.  The  syringes  are  molded  using the
Company's  patented  manufacturing  process.  The healthcare  worker selects the
syringe appropriate for the intended type of injection.  One syringe size is for
subcutaneous  injections,  while  the  others  are  designed  for  intramuscular
injections, depending on the patient's body characteristics.

The Vitajet is also made-up of two  components,  a portable  injector unit and a
disposable  syringe.  It is smaller and lower in cost than other products in the
Company's  needle-free  offering.  The method of operation  and drug delivery is
similar to the Biojector,  except that the Vitajet is powered by a spring rather
than by CO2. It is designed for self-injection and was acquired to fill a gap in
the  Company's  product  line for a  low-cost,  home  use,  needle-free  device.
Vitajet's  current  regulatory  labeling  limits  its  use to the  injection  of
insulin.  The Company  believes  that the product has the  potential  to achieve
regulatory labeling for additional subcutaneous injections. See "Forward Looking
Statements" and "Risk Factors Government Regulation."

<PAGE>

The current  suggested retail list price for the Biojector 2000 professional jet
injector is $995, and the suggested retail list price for Biojector  syringes is
$1.00 a piece. CO2 cartridges are sold for a suggested retail price of $0.50 per
cartridge and average ten injections  per  cartridge.  Discounts are offered for
volume  purchases.  The  current  suggested  retail  price  for  the  Vitajet  3
needle-free  injector  is $399.  A three  month  supply  (13-count)  of  Vitajet
syringes is sold for a suggested retail price of $60.

The Company  has other  products in  development  which are  intended to address
other markets or to enhance the Biojector 2000 system. See "Research and Product
Development."

Blood Glucose Monitoring Business.

The  Company is  currently  in the  development  phase of its  continuous  blood
glucose  monitoring  product and  currently has no products on the market in the
blood  glucose   monitoring   business   segment.   See  "Research  and  Product
Development."

MARKETING AND COMPETITION

Needle-free Injection Business.

Currently,  the  traditional  needle-syringe  is the  primary  method  by  which
intramuscular and subcutaneous injections are administered.

During the last 20 years,  there  have been many  attempts  to develop  portable
one-shot jet  injection  hypodermic  devices.  Some of the  problems  which have
arisen in the attempts to develop such devices include: (a) inadequate injection
power;  (b) little or no  control  of  pressure  and depth of  penetration;  (c)
complexity  of design with related  difficulties  in cost and  performance;  (d)
difficulties in use,  including filling and cleaning;  and (e) the necessity for
sterilization between uses.

In recent years, several spring-driven needle-free injectors have been developed
and  marketed  primarily  for the  injection of insulin.  Each of these  devices
requires regular cleaning as well as filling from a separate  medication  bottle
or vial. Current prices for such injectors range from approximately $400 to $600
per injector.  The Company believes that market  acceptance of these devices has
been limited due to a  combination  of the cost of the devices  coupled with the
difficulties of their use.

Also in recent years,  various versions of a "safety syringe" have been designed
and marketed.  Most versions of the safety syringe generally  involve,  as their
basic  design,  a standard or modified  needle-syringe  with a plastic  guard or
sheathing  surrounding the needle. Such covering is usually retracted or removed
in order to give an injection.  Although the intent of the safety  syringe is to
reduce or eliminate  needlestick  injuries,  the syringes  require  manipulation
after injection and, therefore,  still pose the risk of needlestick injury. They
are also bulky and add to contaminated waste disposal problems.

The Company is currently  focusing it marketing efforts for the Biojector system
in two primary  directions.  The first of these marketing  efforts continues the
Company's  historical  strategy of  marketing  directly  to the  end-user of the
product  by  gaining  acceptance  of the  Biojector  system as a safe,  reliable
alternative to the needle-syringe and safety syringe. These efforts build on the
Company's  established  presence  in the  U.S.  public  health  clinic  and  flu
immunization  markets.  The Company is also  focusing  its direct  marketing  on
creating  arrangements  to  market  the  Biojector  2000  system to the home
healthcare market and the U.S. military.

The second area of marketing  emphasis focuses on creating  licensing and supply
arrangements with leading  pharmaceutical  and biotechnical  companies for whose
products the Biojector  technology  provides either better medical efficacy or a
higher  degree of market  acceptance.  Sales though this channel would be to the
pharmaceutical  or  biotechnology  company whose salesforce would then sell that
company's  own  products  along  with  the  Biojector  system  to the end  user.
Development  of  an  injection  system  for  specific   applications   which  is
anticipated  to be  marketed  by  Hoffmann-La  Roche  is an  example  of such an
arrangement. Other opportunities include the possibility of pre-filled Biojector
syringes which, if developed, could be filled and marketed by the pharmaceutical
or biotechnology company whose product is involved.

Pursuing both of these  marketing  strategies,  the Company plans  eventually to
expand into international markets.

<PAGE>

To lead its direct sales and marketing efforts,  The Company currently employs a
national sales manager who manages a staff of two full-time nurse trainers, 5 to
8 per  diem  part-time  nurse  trainers  and a  half-time  U.S.  military  sales
representative.  Bioject's  direct sales efforts have resulted in the signing of
public  health  agreements  for the state of North  Carolina,  the New York City
Middle Schools, and the health departments in the states of New Mexico, Oklahoma
and  Illinois.  The Company  expects to sign  additional  agreements  with other
public  health  agencies.  In addition,  the Company works closely on a national
basis with the Visiting Nurses Associations for use of the Biojector 2000 system
for flu  immunization.  The  Company  intends to  leverage  its success in these
immunization  programs to attract  pharmaceutical  company strategic partners to
assist  it in  gaining  access to the  physician  office  and other  specialized
markets  where  the  benefits  of  jet  injection  drug  delivery  will  enhance
distribution of their injectable medications.

In August 1994,  Bioject  signed an agreement  with  Homecare  Management,  Inc.
("HMI"),  granting  HMI  exclusive  rights  to  purchase  Bioject's  Needle-Free
Injection  Management System, the Biojector 2000, for use in the home healthcare
market. Sales to HMI commenced in August 1994. In return for HMI's commitment to
purchase a minimum of 8,000  Biojector  units over the  ensuing  two years,  the
Company  granted  volume  pricing  discounts to HMI.  Throughout the term of the
contract the selling price of Biojectors to HMI exceeded  their  standard  cost.
During  fiscal 1995 and 1996,  the Company  sold  approximately  2,100 and 4,300
Biojectors to HMI for total sales revenue including syringes of $1.1 million and
$2.2  million,  respectively.  HMI had not  placed the great  majority  of these
Biojectors with patients pending completion of negotiations with  pharmaceutical
companies for certain pricing concessions for medication to be administered with
the Biojectors.  In January 1996, HMI requested that further shipments under the
contract be suspended.  In February 1996,  the Company  learned from HMI's press
releases  that HMI  expected  to  default  under its loan,  to take  significant
write-offs  for  accounts   receivable  and  inventories,   planned  operational
consolidations,  and would restate certain prior period financial statements. In
fiscal  1997,  the  Company  agreed  to  repurchase  certain  of  the  Biojector
inventories (including up to 6,000 devices) which HMI had on hand for a total of
$660,000 including $322,000 of forgiveness of accounts receivable and payment of
$338,000 in two  installments,  one-half of which was paid in July 1996 and with
the  balance  remaining  outstanding.  The Company  was under no  obligation  to
repurchase these inventories,  and the repurchase was at a substantial  discount
to the original selling price to HMI.

The sale of new  technologies  to  hospitals,  large  clinics  and  other  large
institutions is typically a lengthy process. Introduction of new technologies to
a hospital or other large institution  typically  involves  screening by several
individuals  and  committees  within  the  institution,  including  new  product
evaluation  committees,  infection control officers,  medical staff and business
office  personnel.  Therefore,  in order to shorten the sales cycle, the Company
has focused  its  primary  direct  sales  strategy on the public  health and flu
immunization  markets  where  there  are fewer  and more  concentrated  decision
makers.

The medical equipment market is highly competitive, and competition is likely to
intensify. Many of the Company's existing and potential competitors have been in
business  longer  than the  Company and have  substantially  greater  technical,
financial, marketing, sales and customer support resources. The Company believes
the primary competition for the Biojector 2000 system and other jet injectors it
may  develop  is the  traditional  disposable  needle-  syringe  and the  safety
syringe. Leading suppliers of needle-syringes  include:  Becton-Dickinson & Co.,
Sherwood  Medical Co., a subsidiary of American Home Products Corp.,  and Terumo
Corp. of Japan.  Manufacturers of traditional  needle-syringes compete primarily
on price,  which generally  ranges from  approximately  $0.17 to $0.15 per unit.
Manufacturers of safety syringes compete on features,  quality and price. Safety
syringes generally are priced in a range of $0.25 to $0.45 per unit.

The  Company  expects to compete  with  traditional  needle-syringes  and safety
syringes  based  on  healthcare  worker  safety,  ease of use,  reduced  cost of
disposal, patient comfort, and reduced cost of compliance with OSHA regulations,
but not on purchase price.  However, the Company believes that when all indirect
costs  (including  disposal of syringes  and  testing,  treatment  and  workers'
compensation  expense  related to  needlestick  injuries)  are  considered,  the
Biojector 2000 system will compete effectively. See "Forward Looking Statements"
and "Risk Factors."

<PAGE>

The Company is aware of other portable needle-free injectors on the market today
which are generally focused on subcutaneous  self-injection  applications of 0.5
ml. or less and compete  with the  Vitajet.  However the Company is not aware of
any competing  products  with features and benefits  comparable to the Biojector
2000 system.  The Biojector is suitable for both  intramuscular and subcutaneous
injections  of up to 1 ml.  in the  professional  and  home  injection  markets.
Manufacturers of  needle-syringes,  as well as other companies,  may develop new
products that compete directly or indirectly with the Company's products.  There
can be no  assurance  that the Company will be able to compete  successfully  in
this market. See "Risk Factors - Competition,- "Dependence on Two Technologies".
A variety of new  technologies  (for  example,  transdermal  patches)  are being
developed as alternatives to injection for drug delivery. While the Company does
not believe such technologies have  significantly  affected the use of injection
for drug delivery to-date, there can be no assurance that they will not do so in
the future.

Blood Glucose Monitoring Business.

The diabetic  blood  glucose  monitoring  market is currently  dominated by four
companies:  LifeScan, a subsidiary of Johnson and Johnson,  Boehringer Mannheim,
Miles Laboratories, a subsidiary of Bayer, and MediSense, a subsidiary of Abbott
Laboratories.  All of these  companies  have in vitro blood  glucose  monitoring
systems which use blood test strips and an electronic reader.

Emerging technologies for less invasive monitoring of blood glucose have been in
development  for many years.  There are three broad  modalities of blood glucose
analysis:  Near infrared  spectroscopy  (near-IR),  measurement of  interstitial
fluid  ("ISF"),   the  liquid  between  cells  of  the  skin,  and   transdermal
technologies,  where a patch  applied  to the skin  causes  diffusion  of bodily
fluids to the skin surface from which levels of blood glucose can be measured.

There have been several recent  attempts to introduce  noninvasive in vivo blood
glucose sensors, based on near-IR spectroscopy.  These instruments are currently
large and costly  (around  $10,000),  as well as difficult to calibrate.  Though
some are billed as "portable," they are impractical for ambulatory use.

Two  companies,  TCPI  and  Cygnus  Therapeutics,  are  developing  systems  for
measuring  the blood glucose  concentration  with patch  membrane  technologies.
Through  application  of an electrical  current  through the skin,  interstitial
fluid is brought to the skin's  surface,  where it is  captured  by a patch from
which the glucose element can be measured.  In the case of the TCPI device,  the
patch  is then  removed  from  the skin and  placed  into a reader  for  glucose
measurement.  The  Cygnus  device  has a reader  and  membrane  integrated  in a
wristwatch  which takes periodic  readings and averages them to determine  blood
glucose levels.

The Company has not yet fully developed and  commercialized its continuous blood
glucose  monitoring  technology.  However,  based  on the  expected  design  and
performance  of its  continuous  blood glucose  monitoring  device,  the Company
expects to compete effectively based on the following anticipated key benefits:

To patients:
- -    Real-time  measurement of blood glucose  concentration leading to a better,
     more  reliable  monitoring  of the blood  sugar  level  with the  resulting
     opportunity  to reduce  the near and  long-term  medical  complications  of
     diabetes.
- -    Superior Information:  Continuous availability of blood glucose levels in a
     convenient and pain free format.
- -    Lightweight and discreet.
- -    Convenience;  anticipated  once-per-day  application to provide  continuous
     results all day without further activation by the patient.

To third party payors:
- -    Real-time  measurement of blood glucose  concentration leading to a better,
     steadier  regulation of the blood sugar level,  translating  to a potential
     reduction of diabetic complications and their associated cost.
- -    Freedom from the pain and  inconvenience of frequent blood tests leading to
     better  patient  compliance,  which  translates  to  better  blood  glucose
     control, fewer long term complications, and lower costs.

To healthcare providers:
- -    Superior Information:  Real-time measurement of blood glucose concentration
     leads to steadier  regulation of the blood sugar levels,  superior provider
     capabilities, and improved patient care.
- -    Continuous monitoring via once-a-day application greatly reducing the labor
     requirements  associated with  patient-nurse  interactions  required by the
     static tests currently employed to monitor patients' blood glucose levels.

PATENTS AND PROPRIETARY RIGHTS

Needle-free Injection Business.

The Company  believes that  technology  incorporated  in its currently  marketed
injection  device and  single-dose  disposable  plastic  syringes as well as the
technology  of products  under  development  in both the jet injection and blood
glucose monitoring business segments coupled with the technology and ease of use
of the  products  acquired  in  the  Vitajet  acquisition  give  it  significant
advantages  over the  manufacturers  of other  jet  injection  systems  and over
prospective competitors seeking to develop similar systems. The Company attempts
to  protect   its   technology   through  a   combination   of  trade   secrets,
confidentiality agreements and procedures and patent prosecution.

The  Company  has three U.S.  patents  which  were  issued  with  respect to jet
injection  technology  incorporated  in earlier  versions  of its jet  injection
systems and which expire from July 2007 to November 2008.  Seven additional U.S.
patents  have  been  issued  which  protect  developments  incorporated  in  the
Biojector 2000 system.  These patents  incorporate a number of claims  including
claims regarding the jet injection system's design, method of operation, certain
aspects  of the  syringe  design  and the method of  manufacturing  the  syringe
orifice.  The  Company  has also  been  granted  a patent  relating  a drug vial
adapter.  The Company has made additional  patent filings  regarding  pre-filled
syringe  technologies  and  adapters  for drug vial  access.  The  Company  also
generally files patent applications in Canada, Europe and Japan at the times and
under the  circumstances it deems filing to be appropriate  under the procedures
in  place in each  jurisdiction.  There  can be no  assurance  that any  patents
applied for will be granted or that patents held by the Company will be valid or
sufficiently broad to protect the Company's  technology or provide a significant
competitive  advantage.  See "Risk  Factors."  The Company  also relies on trade
secrets   and   proprietary   know-how   that  it  seeks  to   protect   through
confidentiality  agreements  with  its  employees,  consultants,  suppliers  and
others.  There can be no assurance that these  agreements  will not be breached,
that the  Company  would have  adequate  remedies  for any  breach,  or that the
Company's  trade  secrets  will not  otherwise  become  known to or be developed
independently by competitors. In addition, the laws of foreign countries may not
protect the Company's  proprietary  rights to its technology,  including  patent
rights, to the same extent as the laws of the U.S.

Although the Company believes that it has independently developed its technology
and attempts to assure that its products do not infringe the proprietary  rights
of others,  if infringement  were alleged and proved,  there can be no assurance
that the Company could obtain  necessary  licenses on terms and conditions  that
would not have an adverse affect on the Company. The Company is not aware of any
asserted claim that the Biojector 2000, Vitajet or any product under development
violates the proprietary rights of any person.

If a dispute arises concerning the Company's  technology,  litigation that could
result in  substantial  cost to and  diversion of effort by the Company might be
necessary  to enforce the  Company's  patents,  to protect the  Company's  trade
secrets or  know-how  or to  determine  the scope of the  proprietary  rights of
others.  Adverse  findings  in any  proceeding  could  subject  the  Company  to
significant  liabilities to third parties,  require the Company to seek licenses
from third  parties or  otherwise  adversely  affect  the  Company's  ability to
manufacture and sell its products.

Blood Glucose Monitoring Business.

The continuous blood glucose  monitoring system concept and proprietary  aspects
of the design are covered by various patents . Corresponding patent applications
have been filed with the PCT,  designating all member  countries,  including the
United States, E.U. and Japan, as well as in Taiwan and South Africa. Additional
patent  applications  will be filed in the course of the  GlucoTrax  development
program.  These applications will cover new,  innovative aspects and refinements
of the product.

GOVERNMENTAL REGULATION

Needle-free Injection and Blood Glucose Monitoring Businesses.

The Company's  products and  manufacturing  operations  are subject to extensive
government  regulations,  both in the U.S. and abroad. In the U.S., the Food and
Drug Administration  ("FDA") administers the Federal Food, Drug and Cosmetic Act
(the  "FD&C")  and  has  adopted  regulations,  including  those  governing  the
introduction of new medical  devices,  the observation of certain  standards and
practices with respect to the manufacturing and labeling of medical devices, the
maintenance  of certain  records and the  reporting  of  device-related  deaths,
serious injuries, and certain malfunctions to the FDA. Manufacturing  facilities
and certain  Company  records are also subject to FDA  inspections.  The FDA has
broad  discretion  in enforcing  the FD&C and the  regulations  thereunder,  and
noncompliance  can result in a variety of regulatory  steps ranging from warning
letters,  product  detentions,  device alerts or field  corrections to mandatory
recalls, seizures, injunctive actions and civil or criminal penalties.

The FD&C provides that,  unless exempted by regulation,  medical devices may not
be  commercially  distributed  in the U.S.  unless  they  have been  cleared  or
approved  by the  FDA.  The  FD&C  provides  two  basic  review  procedures  for
pre-market  clearance or approval of medical  devices.  Certain products qualify
for a  submission  authorized  by  Section  510(k)  of  the  FD&C,  wherein  the
manufacturer   provides   the  FDA  with  a  premarket   notification   ("510(k)
notification")  of  the  manufacturer's  intention  to  commence  marketing  the
product.  The  manufacturer  must,  among other things,  establish in the 510(k)
notification  that the  product to be marketed is  substantially  equivalent  to
another legally marketed  product,  (i.e., that it has the same intended use and
that it as safe and  effective as a legally  marketed  device and does not raise
questions of safety and  effectiveness  that are different from those associated
with the legally marketed device).  Marketing may commence when the FDA issues a
letter finding  substantial  equivalence to such a legally marketed device.  The
FDA may require,  in connection with the 510(k) submission,  that it be provided
with animal and/or human test results.  If a medical device does not qualify for
the 510(k) procedure,  the manufacturer  must file a premarket  approval ("PMA")
application.  A PMA must  show  that the  device  is safe and  effective  and is
generally a much more complex  submission than a 510(k)  notification  typically
requiring more extensive prefiling testing and a longer FDA review process.

A 510(k)  notification  is required when a device is being  introduced  into the
market for the first  time.  A 510(k)  notification  is also  required  when the
manufacturer  makes a change or modification to an already  marketed device that
could  significantly  affect safety or effectiveness,  or where there is a major
change or  modification  in the intended  use of the device.  When any change or
modification  is made in a device  or its  intended  use,  the  manufacturer  is
expected  to  make  the  initial  determination  as to  whether  the  change  or
modification  is of a kind that  would  necessitate  the  filing of a new 510(k)
notification. The FDA's regulations provide only limited guidance in making this
determination.

In April 1987,  the Company  received  510(k)  marketing  clearance from the FDA
allowing the Company to market a hand-held  CO2-powered  jet  injection  system.
Although the  Biojector  2000 system  incorporates  changes from the system with
respect to which the Company's 1987 510(k) marketing  clearance was received and
expands its intended use, the Company 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 and that,
accordingly,  the 1987  510(k)  clearance  permitted  the  Company to market the
Biojector 2000 system in the U.S. In June 1994, the Company  received  clearance
from the FDA under 510(k) to market a version of its Biojector  2000 system in a
configuration targeted at high volume injection  applications.  In October 1996,
the Company  received 510(k)  clearance for a non-needle  disposable vial access
device.  In March 1997, the Company  received  additional  510(k)  clearance for
certain  enhancements  to its Biojector 2000 system.  The Company  currently has
applications  pending before the FDA for 510(k) clearance of the B2020 1.5ml jet
injector,  the B4000 self-injector.  There can be no assurance that the FDA will
concur with the  Company's  determination  that the products can be qualified by
means of a 510(k) submission.

<PAGE>

The  continuous  blood  glucose  monitoring  system  will  be  designed  to meet
international standards of product safety, reliability and biocompatibility.  In
the U.S., while the Company believes that the FDA, based on an earlier clearance
of a "Biostator Monitor", sold by Miles Laboratories,  will allow the continuous
blood  glucose   monitoring   system  to  be  sold  under  a  510(k)  pre-market
notification, a final determination has not been made in this regard and there
can be no  assurance  that the FDA  will  allow  the use of a 510(k)  pre-market
notification. See "Risk Factors - Governmental Regulation".  European regulatory
clearance will be in accordance with the essential  requirements  set out in the
new Medical Device Directives, which will come into law in June 1998.

The Company  continues to seek  arrangements  with  pharmaceutical  companies to
develop pre-filled  Biojector syringe  applications to permit the pharmaceutical
companies to market their products packaged in Biojector  prefilled  containers.
See "Research and Product Development." Before pre-filled Biojector syringes may
be distributed for use in the U.S., certain FDA-mandated stability tests may be
required of those  pharmaceutical  companies.  Pre-filled syringes involve drugs
packaged as a component of a medical device.  It is current FDA policy that such
pre-filled  syringes,  which are  considered  to be  combination  products,  are
evaluated  by the  FDA as  drugs  rather  than  medical  devices.  Marketing  of
pre-filled syringes by pharmaceutical companies will require prior clearance via
a new or amended Drug Application ("NDA") or an Abbreviated New Drug Application
("ANDA").  An NDA is a complex submission required to establish that a drug will
be safe and effective for its intended uses. An ANDA is a less detailed  process
which does not require,  among other things, that the applicant provide complete
reports of  preclinical  and  clinical  studies of safety  and  efficacy  as are
required for NDAs. Assuming that the drugs used in the pre- filled syringes have
previously  been approved by the FDA for injection,  the FDA will likely require
that ANDAs, rather than NDAs, be submitted.  The Company believes that if a drug
to be used in the  Company's  pre-filled  syringe were already the subject of an
approved NDA or ANDA for intramuscular or subcutaneous injection, the main issue
affecting  clearance for use in the pre-filled  syringe would be the adequacy of
the syringe to store the drug, to assure its stability  until used and to safely
deliver the proper dose.  See "Forward  Looking  Statements"  and "Risk  Factors
Government Regulation."

The  FDA  also  regulates  the  Company's   quality  control  and  manufacturing
procedures  by  requiring  the  Company  and  its  contract   manufacturers   to
demonstrate   compliance  with  current  Good  Manufacturing   Practice  ("GMP")
Regulations.  These  regulations  require,  among  other  things,  that  (i) the
manufacturing  process must be regulated  and  controlled  by the use of written
procedures and (ii) the ability to produce devices which meet the manufacturer's
specifications  must be  validated by  extensive  and detailed  testing of every
aspect of the process.  They also require  investigation  of any deficiencies in
the   manufacturing   process  or  in  the   products   produced   and  detailed
record-keeping.  Further,  the FDA's  interpretation  and  enforcement  of these
requirements has been increasingly strict in recent years and seems likely to be
even more stringent in the future.  Failure to adhere to GMP requirements  would
cause the products produced to be considered in violation of the Act and subject
to enforcement  action.  The FDA monitors  compliance with these requirements by
requiring  manufacturers  to register  with the FDA, and by  subjecting  them to
periodic FDA inspections of manufacturing  facilities. If the inspector observes
conditions  that  might  be  violated,   the  manufacturer  must  correct  those
conditions or explain them  satisfactorily,  or face potential regulatory action
that might include physical removal of the product from the marketplace.

The FDA's Medical Device Reporting  Regulation requires that the Company provide
information  to the FDA on the  occurrence  of any  death  or  serious  injuries
alleged to have been associated with the use of the Company's products,  as well
as any product  malfunction  that would likely cause or contribute to a death or
serious injury if the malfunction  were to recur.  In addition,  FDA regulations
prohibit a device from being marketed for  unapproved or uncleared  indications.
If  the  FDA  believes  that  the  company  is  not  in  compliance  with  these
regulations,  it can institute proceedings to detain or seize products,  issue a
recall,  seek injunctive  relief or assess civil and criminal  penalties against
such company.

The use and manufacture of the Company's  products are subject to OSHA and other
federal,  state and local laws and regulations  relating to such matters as safe
working conditions for healthcare  workers and Company employees,  manufacturing
practices,  environmental  protection  and disposal of hazardous or  potentially
hazardous  substances  and the  policies of  hospitals  and clinics  relating to
compliance  therewith.  There can be no  assurance  that the Company will not be
required to incur  significant  costs to comply with such laws,  regulations  or
policies  in the future,  or that such laws,  regulations  or policies  will not
increase the costs or restrictions  related to the use of the Company's products
or otherwise have a materially  adverse effect upon the Company's  ability to do
business. See "Risk Factors."
<PAGE>

Laws and regulations regarding the manufacture,  sale and use of medical devices
are  subject  to change and depend  heavily on  administrative  interpretations.
There can be no assurance that future changes in regulations or  interpretations
made by the FDA, OSHA or other regulatory bodies,  will not adversely affect the
Company.

Sales of medical  devices  outside of the United  States are  subject to foreign
regulatory requirements. The requirements for obtaining premarket clearance by a
foreign  country  may differ  from those  required  for FDA  clearance. Devices
having an effective  510(k) clearance or PMA may be exported without further FDA
authorization.  FDA authorization is generally required in order to export other
medical devices.

RESEARCH AND PRODUCT DEVELOPMENT

Needle-free Injection Business.

Research and development  efforts are focused on enhancing the Company's current
product  offerings and on developing  both new jet injection  technology and new
products. The Company continues to use clinical,  magnetic resonance imaging and
tissue studies to determine the  reliability and performance of new and existing
products.  As of March 31, 1998, the Company's research and product  development
staff,  including  clinical  and  regulatory  staff  members,   consisted  of  7
employees.  During fiscal 1996,  1997 and 1998,  the Company spent $1.9 million,
$1.6 million, and $884,000, respectively, on research and development.

In March 1994,  the Company  entered into an agreement with Schering AG, Germany
("Schering"),  for the  development of a  self-injection  device for delivery of
Betaseron (R) to multiple sclerosis  patients.  During fiscal 1995 through 1997,
the Company developed prototypes to Schering  specifications which were accepted
by Schering.  During fiscal 1997,  the Company  entered into a supply  agreement
with Schering and commenced  activities  related to full  production of the self
injector.  Schering loaned the Company a total of $1.6 million to purchase molds
and tooling for production of the product. In January 1997, the Company received
notice that its contract with Schering would be cancelled.  Under  provisions of
the  contract,  Schering  had the option of canceling  the  agreement if the FDA
required  extensive  clinical studies beyond an originally planned safety study.
Schering  received  a review  letter  from the FDA  which  would  have  required
Schering  to  conduct  additional  material  clinical  studies  in  order to use
non-traditional  delivery mechanisms with its Betaseron (R) product. Under terms
of the contract, Schering was required to convert its $1.6 million note due from
Bioject  into  approximately  460,000  shares  of  Bioject  common  stock  at  a
conversion  price of $3.50 per share. In addition,  $106,000 of accrued interest
was converted  into  approximately  27,000  shares of Bioject  common stock at a
conversion price of $3.50 per share. The Company retained ownership of the molds
and tooling.  The B4000  self-injector,  which was  developed as a result of the
Schering  agreement,   is  currently  awaiting  regulatory  clearance  prior  to
marketing. See "Risk Factors - Governmental Regulation".

In  January  1995,  the  Company  signed  a  joint  development  agreement  with
Hoffmann-La  Roche ("Roche") to develop  proprietary  drug delivery  systems for
Roche products.  The agreement provides for Bioject to develop,  manufacture and
sell   Biojector  jet  injection  drug  delivery   systems   designed  to  Roche
specifications.  In return, Bioject has granted Roche exclusive worldwide rights
to  distribute  these  systems and their  components  for use with certain Roche
products.  Hoffmann-La  Roche  Inc.  is  the  United  States  affiliate  of  the
multinational group of companies headed by Roche Holding of Basel,  Switzerland,
one of the world's leading, research-intensive healthcare companies.

As of 1995 fiscal year end,  the  Company  had  commenced  design of a prototype
device and had agreed with Roche on product specifications.  During fiscal 1996,
the Company  developed  and  delivered  to Roche  preproduction  prototypes  for
testing and developed the clinical preproduction prototypes which were delivered
to Roche in April 1996.  As of fiscal 1997 year end,  the Company and Roche were
finalizing  their  submission  to obtain  regulatory  clearance  to  market  the
product.  As of the end of fiscal 1998,  the Company had submitted its component
of the proprietary drug delivery system for regulatory clearance.

In February  1995,  Hoffmann-La  Roche paid a one-time  licensing  fee  totaling
$500,000.  The agreement provides that it will pay specified product development
fees on an agreed upon schedule of which $400,000 was recognized in fiscal 1996,
$500,000 was  recognized  in fiscal 1997 and $500,000 was  recognized  in fiscal
1998.


<PAGE>

In March,  1998 the  Company  acquired  the assets of Vitajet  Corporation  in a
stock-for-assets  exchange.  The Company paid 100,000 shares of its common stock
for certain molds, tooling, patent rights and customer lists, the value of which
totaled $134,400 at the date of acquisition. In addition to shares already paid,
the Company is obligated  to issue 60,000  shares of its common stock in each of
the three years subsequent to the acquisition if certain development  milestones
are met.  Up to an  additional  90,000  shares is also  payable  subject  to the
Company realizing specified,  aggregate levels of incremental revenue during the
three  years  subsequent  to the  Vitajet  acquisition  as a result  of sales of
products acquired from or developed by Vitajet

In addition to activities  described above, the Company is seeking  arrangements
with  pharmaceutical  and  biotechnology  companies  for the  use of  pre-filled
syringes to  eliminate  the filling and  measuring  procedures  associated  with
traditional  injection of medications.  Before pre-filled Biojector syringes may
be distributed for use in the U.S., these companies must commit to the packaging
and  distribution of their products in this manner and to the time and financial
resources necessary for FDA review and clearance. This process could be lengthy.
See "Business -  Governmental  Regulation."  There can be no assurance that such
companies  will  commit  efforts  to  develop  pre-filled  packaging  and pursue
regulatory  clearance  or that  regulatory  clearance  of  pre-filled  Biojector
syringes will be obtained.

The Company  intends to continue  research and development  efforts  designed to
further its understanding of the physics and physiology of jet injection.  These
efforts will include  further  clinical  studies to demonstrate  efficacy of jet
injection  and to  evaluate  new  products  and  enhancements  to the  Company's
existing products.  To advance these studies, in April 1994 the Company formed a
Department of Clinical Affairs  research group,  which initiates and coordinates
these studies.

Blood Glucose Monitoring Business.

In October 1997,  the Company  signed a joint  development  agreement  with Elan
Corporation,  plc ("Elan") to license from Elan certain continuous blood glucose
monitoring  technology (the "License") and then to commercialize that technology
for manufacture and world-wide distribution.  To date, the Company has continued
testing and development of a clinical prototype and has scheduled a small, human
clinical  study of the  prototype  device for the first  quarter of fiscal 1999.
Based on the  results of this  study,  the  Company  will then plan and  conduct
comprehensive  clinical  trials of the  monitoring  system which are intended to
support its  applications to the FDA to market the product in the United States.
See "Management's  Discussion and Analysis of Financial Condition and Results of
Operations".

MANUFACTURING

Needle-free Injection Business.

The Company  assembles the Biojector 2000 and related  syringes from  components
purchased from outside  suppliers.  Prior to  introduction of the Biojector 2000
system in 1993,  the Company had not engaged in  manufacturing  on a  commercial
scale. However, in connection with that introduction,  the Company increased its
manufacturing  capabilities and built inventories to support anticipated product
sales.

Throughout  fiscal 1994 and 1995,  the Company's  manufacturing  processes  were
primarily  manual.  These  processes  did not permit the  Company to produce its
products  at costs which would  allow it to operate  profitably.  During  fiscal
1996,  the Company  implemented  a plan to increase  manufacturing  capacity and
refine  production  methods  to meet  anticipated  future  demand  and to reduce
product  costs.  For  the  Biojector  2000,  cost  reduction   efforts  included
converting  from a two-piece to a one-piece  housing,  converting  to continuous
process   manufacturing  and  implementing   volume  purchasing   programs  from
suppliers.  For  the  Biojector  syringes,  these  efforts  included  increasing
supplier mold capacity and automating  final  assembly and packaging.  See "Risk
Factors - Limited Manufacturing Experience, Need to Reduce Unit Cost."

<PAGE>

During fiscal 1998, the Company,  having a sufficient inventory of jet injectors
on-hand  as a  result  of the  repurchase  of  product  from  HMI,  focused  its
manufacturing  efforts on refining the manufacturing  processes and efficiencies
of the syringe  manufacturing line. See "Marketing and Competition - Needle-Free
Injection Business".

In order to  succeed at  expanding  manufacturing  capacity  and  reducing  unit
production cost, the Company must attract and retain qualified  assembly workers
and must  establish and maintain  relationships  with suppliers that can deliver
large  quantities  of components  that meet  applicable  quality  standards in a
timely and reliable manner at acceptable prices.

Blood Glucose Monitoring Business.

At  present,  the Company has no  manufacturing  operation  related to the blood
glucose  monitoring  system.  When  approved  for sale,  the Company  intends to
manufacture the device in its own facilities,  the location of which has not yet
been determined.

EMPLOYEES

As of March 31, 1998,  the Company had 33 full-time  employees  with 4 employees
engaged in research  and product  development,  2 in sales and  marketing,  2 in
technical  product support,  13 in manufacturing and 12 in  administration.  The
Company  engages a limited  number of  part-time  consultants  who  assist  with
research and development, sales and marketing and investor relations activities.
The Company also  employs  temporary  contract  workers  primarily  for assembly
operations,  the number of which varies, depending upon production requirements.
As of March 31,  1998,  there were 4  consultants,  5 to 8 per diem nurses and 1
contract/temporary  worker  employed  by the  Company.  None  of  the  Company's
employees is represented by a labor union.

PRODUCT LIABILITY

The  Company  believes  that  its  products  reliably  inject  medications  both
subcutaneously  and  intramuscularly   when  used  in  accordance  with  product
guidelines.  The Company's current insurance  policies provide coverage at least
equal to an  aggregate  limit of $11  million  with  respect to certain  product
liability  claims.  The Company has not experienced any product liability claims
to date.  There can be no assurance,  however,  that the Company will not become
subject to such claims,  that the Company's  current  insurance would cover such
claims,  or that  insurance  will continue to be available to the Company in the
future.  The Company's  business may be adversely  affected by product liability
claims.

RISK FACTORS

Investment in the  securities of the Company  involves a high degree of risk. In
addition to the other  information in this annual report,  the following factors
should be considered  carefully in evaluating the Company and its business.  The
Company cautions the reader that this list of factors may not be exhaustive.

Uncertainty of Market Acceptance.  The Company's success will depend upon market
acceptance of its jet injection drug delivery system, the Biojector 2000 system,
the blood glucose  monitoring  system and, to a lesser  extent,  other  products
under development. 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 virtually eliminates the associated risk of these injuries;  however,

<PAGE>

the cost per injection is significantly  higher.  There can be no assurance that
the Biojector  2000 system will compete  successfully.  A previous jet injection
system  manufactured by the Company did not achieve market  acceptance and is no
longer being  marketed.  The Biojector  2000 was  introduced in January 1993. To
date,  the major portion of sales have been to HMI,  which units were not placed
in service and which the Company has  repurchased  at a substantial  discount to
the original  selling price after the  cancellation  of its agreement  with HMI.
Failure of the  Biojector  2000  system to gain market  acceptance  would have a
material  adverse  effect on the  Company's  financial  condition and results of
operations.

Uncertainty of New Product  Development.  The Company's joint venture with Elan,
JV Sub, intends to develop certain  technology  licensed from Elan and to create
an ambulatory monitoring system which permits the continuous monitoring of blood
glucose  levels in persons with  diabetes.  The system is in the early stages of
development,  and there can be no assurance  that JV Sub will be  successful  in
developing a product or that any such product can be manufactured or marketed in
a commercially  viable  manner.  It also is likely that  significant  additional
levels of funding will be required to complete  development  of the  technology,
which will likely  require the future  issuance of debt or equity  securities by
either the Company or JV Sub. Further,  there can be no assurance that, should a
blood  glucose  monitoring  system be  developed,  such system would receive the
requisite governmental clearance. See "Governmental Regulation."

History of Losses;  Uncertain  Profitability.  Since its formation in 1985,  the
Company has incurred significant annual operating losses and negative cash flow.
At March 31, 1998, the Company had an accumulated deficit of $50.9 million,  $12
million of which related to the fiscal 1998 write-off,  after minority interest,
of  in-process  research  and  development   acquired  in  connection  with  the
acquisition of blood glucose monitoring technology from Elan. Historically,  the
Company's  revenues have been derived  primarily  from  licensing and technology
fees and from limited product sales, which were principally sales to dealers for
the stocking of inventories and to HMI. More recently,  the Company has sold its
products to end-users,  primarily to public health clinics for  vaccinations and
to nursing  organizations  for flu  immunizations.  The Company has not attained
profitability at these sales levels . There can be no assurance that the Company
will be able to  generate  significant  revenues or achieve  profitability.  See
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations".

Possible  Termination of the License.  Pursuant to the terms of the License, the
License may be terminated under certain conditions.  In the event that 15% of JV
Sub's  equity  is  acquired  by  any  one of a  number  of  specified  companies
identified  by Elan as actual or potential  competitors,  or any other entity to
which Elan does not consent, which consent shall not be unreasonably withheld in
the case of such other  unspecified  companies,  the License may be  immediately
terminated at Elan's option.  Further,  the License  itself is contingent,  on a
country-by-country   basis,  on  JV  Sub's  diligently   seeking  and  obtaining
regulatory  marketing  clearance  for  licensed  products and on JV Sub's timely
commercial launch of the licensed products in countries where such clearance has
been obtained.  Termination of the License may have a material adverse effect on
the Company's financial condition and results of operations.

Need for Additional  Financing.  The Company's revenues from operations have not
been  sufficient  to  satisfy  its cash  requirements  and it has  relied on the
proceeds  of  sales  of  equity  securities  to fund  its  operations.  The Elan
Transaction involves significant future financial  commitments by the Company to
fund the development and marketing  activities of JV Sub, as well as significant
payment  obligations,  totaling  $15.5  million,  by JV Sub to Elan  as  product


<PAGE>

development milestones are met. These payment obligations are in addition to the
Company's  cash  requirements  relating  to  current  activities  involving  the
Company's  jet  injection  technology.  The  Company  plans  to  fund  its  cash
requirements  through  revenues,  debt  and  sales  of  equity  securities,  and
anticipates  that JV Sub will  fund its  activities  through  debt and  sales of
equity  securities to the Company and Elan or to third parties.  There can be no
assurance that  financing  sufficient to fund either the Company's jet injection
business  activities or blood glucose  monitoring  business  activities  will be
obtained on  favorable  terms or at all.  Failure to obtain  adequate  financing
would have a material adverse impact on the Company's  business and could result
in  defaults  on the  Company's  or JV Sub's  obligations  relating  to the Elan
Transactions,  loss of JV Sub's  rights to the  technology  under  the  License,
dilution of the Company's  interest in JV Sub or the need to curtail  operations
of the  Company or JV Sub due to  inadequate  cash  resources  or other  adverse
consequences.  The sale of equity  securities on  unfavorable  terms to meet the
Company's  obligations  could  result  in  material  dilution  to  the  existing
shareholders.

Effects of Convertible Preferred Stock. The Company's Common Stock is subject to
the rights and  preferences of the Series A and B Convertible  Preferred  Stock,
which has a liquidation  preference  of $12.405  million plus accrued and unpaid
dividends.   Further,  the  Series  A  and  B  Convertible  Preferred  Stock  is
convertible  to  Common  Stock at a  conversion  price of $1.50 per share at any
time, and at the end of seven years unless  earlier  converted by the holders or
redeemed by the Company,  the shares Series A and B Convertible  Preferred Stock
and accrued but unpaid dividends convert  automatically into Common Stock at the
conversion  price  equal to the  lesser  of $1.50  per  share or 80% of the then
prevailing market price of Common Stock. Accordingly, conversion of Series A and
B  Convertible  Preferred  Stock to Common  Stock could  result in  issuances of
significant  amounts  of Common  Stock at prices  lower than  prevailing  market
prices at the time of conversion.  Should the Company issue Series C Convertible
Preferred Stock or other similar series of Preferred Stock to Elan to enable the
Company  to fund  capital  contributions  to JV Sub,  the  aggregate  amount  of
Preferred  Stock   liquidation   preferences  and  Common  Stock  issuable  upon
conversion of Preferred Stock would increase.

Limited  Manufacturing  Experience;  Need to Reduce  Unit Cost.  The Company has
limited experience manufacturing its products in commercially viable quantities.
The Company has increased its production  capacity for the Biojector 2000 system
through automation of, and changes in, production methods.  The current cost per
injection  of the  Biojector  2000 system is  substantially  higher than that of
traditional  needle-syringes,  its principal  competition.  A key element of the
Company's  business strategy has been to reduce the overall  manufacturing  cost
through automating production and packaging.  There can be no assurance that the
Company will be able to develop and implement  effective high volume  production
or achieve necessary unit cost reductions.  Failure to do either would adversely
affect the Company's  financial  condition and results of operations.  While the
Company believes that its experience  manufacturing  the Biojector  enhances the
probability  of its success in  manufacturing  the  Vitajet,  the Company has no
experience  manufacturing the Vitajet and as of March 31, 1998 has not installed
a manufacturing line to produce the Vitajet.  There can be no assurance that the
Company will be able to successfully manufacture the Vitajet at a unit cost that
will allow the product to be sold  profitably.  Failure to do so would adversely
affect  the  Company's  financial  condition  and  results  of  operation.   See
"Management's  Discussion  and  Analysis of Financial  Condition  and Results of
Operations" and "Manufacturing"

Governmental Regulation. The Company's products and manufacturing operations are
subject to extensive government regulation,  both in the U.S. and abroad. 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, the Company received  clearance
from the FDA under Section 510(k) of the FD&C to market a hand-held  CO2-powered
jet 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

<PAGE>

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 the Company's 1987 510(k) marketing  clearance was received and
expands its intended use, the Company 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,  the  Company  further  concluded  that the 1987  510(k)  clearance
permitted  the Company to market the  Biojector  2000 system in the U.S. In June
1994,  the  Company  received  clearance  from the FDA under  510(k) to market a
version of its Biojector 2000 system in a configuration  targeted at high volume
injection  applications.  In October 1996, the Company received 510(k) clearance
for a needle-free  disposable  vial access  device.  In March 1997,  the Company
received  additional 510(k) clearance for certain  enhancements to its Biojector
2000 system.  The Company currently has applications  pending before the FDA for
510(k)  clearance of the B2020 1.5ml jet  injector and the B4000  self-injector.
There  can  be no  assurance  that  the  FDA  will  concur  with  the  Company's
determination  that  the  products  can  be  qualified  by  means  of  a  510(k)
submission.

Future changes to manufacturing procedures could necessitate the filing of 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  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  prefilled 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.
See "Governmental Regulation".

No clearances from the FDA have been obtained for the marketing of products that
may be developed based on the blood glucose monitoring  technology licensed from
Elan.  The  Company is  researching  and has not  finally  determined  which FDA
clearances will be required with respect to any products developed based on this
technology.  The Company  anticipates that extensive testing and FDA review will
be  required  of any  such  product,  and  there  can be no  assurance  that FDA
clearance will be obtained in a timely manner or at all.

FDA  regulatory  processes  are time  consuming and  expensive.  There can be no
assurance that product applications  submitted by the Company will be cleared or
approved by the FDA. In addition, the Company's 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.

Distribution  of the Company's  products in countries other than the U.S. may be
subject to regulation in those  countries.  An application was made to the Japan
Ministry  of Health and  Welfare  to obtain  necessary  approvals  to market the
Biojector  2000  system in Japan  which was not  carried  to  completion  by the
Company's then current Japanese distributor. See "Governmental Regulations".


<PAGE>

Uncertainty  in  Healthcare  Industry.  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 payors 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  injection  systems,  cost  control  policies of third party
payors, including government agencies, may adversely affect use of the Biojector
2000 system.

Dependence  on  Third-Party  Relationships.  The Company is  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.

The  Company's  current  manufacturing  processes  for the  Biojector  2000  jet
injector and disposable syringes as well as manufacturing  processes anticipated
to produce the Vitajet consist primarily of assembling  component parts supplied
by outside  suppliers.  Certain of these components are currently  obtained from
single  sources,  with some  components  requiring  significant  production lead
times.  In the past,  the  Company  has  experienced  delays in the  delivery of
certain components,  although to-date no such delays have had a material adverse
effect on the Company's  operations.  There can be no assurance that the Company
will not experience  delays in the future,  or that such delays would not have a
material  adverse  effect on the  Company's  financial  condition  and result of
operations. See "Manufacturing".

The  Company has entered  into  agreements  with  certain  major  pharmaceutical
companies for development and distribution of jet injection  systems and for the
development  and  commercialization  of a continuous  blood  glucose  monitoring
system.  These companies have the right to terminate these agreements at certain
phases as  defined  in the  agreements.  There can be no  assurance  that  these
companies' interest and participation in the projects will continue.  Failure to
receive  additional  funding from these  companies  could  adversely  affect the
development and production of the products  involved and,  correspondingly,  the
Company's financial condition and results of operations.

Ability to Manage Growth. If the Company's  products achieve market  acceptance,
the Company  expects to achieve rapid growth.  This growth strategy will require
expanded  customer  services and support,  increased  personnel  throughout  the
Company,  expanded  operational and financial systems, and the implementation of
new and expanded control procedures.  There can be no assurance that the Company
will be able to attract  qualified  personnel or  successfully  manage  expanded
operations.  As the  Company  expands,  it may  from  time  to  time  experience
constraints  that would adversely  affect its ability to satisfy customer demand
in a timely fashion. Failure to manage growth effectively could adversely affect
the Company's financial condition and results of operations.

Competition.  The medical equipment market is highly competitive and competition
is  likely  to  intensify.   The  Company's   products  compete  primarily  with
traditional  needle-syringes,  "safety syringes" and also with other alternative
drug  delivery  systems.  While the  Company  believes  its  products  provide a
superior drug delivery  method,  there can be no assurance that the Company will
be able to compete  successfully with existing drug delivery  products.  Many of
the  Company's   competitors  have  longer   operating   histories  as  well  as
substantially  greater  financial,  technical,  marketing  and customer  support
resources than the Company.  There can be no assurance that one or more of these
competitors  will not develop an alternative  drug delivery system that competes
more directly with the Company's products,  or that the Company's products would
be able to  compete  successfully  with such a product.  Further,  should JV Sub
develop  an  ambulatory  blood  glucose  monitoring  system  which  obtains  all
necessary  regulatory  clearances,  there can be no  assurance  that  either the
Company's or JV Sub's competitors will not develop other competing  systems,  or
that JV Sub's system would be able to compete successfully with other systems or
products.


<PAGE>

Dependence on Two  Technologies.  The  Company's  strategy has been to focus its
development and marketing efforts on its jet injection technology.  The strategy
of its Joint Venture with Elan is to focus on development and  commercialization
of a continuous blood glucose monitoring system. Focus on these two technologies
leaves the  Company  vulnerable  to  competing  products  and  alternative  drug
delivery  systems,  as well as to  alternative  methods to monitor blood glucose
levels in diabetics.  The Company believes 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  and   transdermal   diffusion   "patches."   In   addition,
pharmaceutical  companies  frequently attempt to develop drugs for oral delivery
instead of  injection.  The Company also believes that there will be high market
demand for a minimally  invasive  blood glucose  monitoring  system such as that
being  developed  by the  Company  and that the size of that  market will likely
attract  significant  competition  to the  Company's  blood  glucose  monitoring
product.

While the Company  believes that for the foreseeable  future there will continue
to be a  significant  need  for  injections,  there  can  be no  assurance  that
alternative  drug delivery methods will not be developed which are preferable to
injection.  Further,  there can be no assurance that  alternative  blood glucose
monitoring  systems will not be  developed  which are  preferable  to that to be
developed by the Company.

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

Product Liability.  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. The Company currently  maintains  product liability  insurance and,
to-date,  has not  experienced  any product  liability  claims.  There can be no
assurance,  however,  that the Company will not be subject to such claims,  that
the  Company's  current  insurance  would cover such  claims,  or that  adequate
insurance  will continue to be available on  acceptable  terms to the Company in
the  future.  The  Company's  business  could be  adversely  affected by product
liability claims.

Dependence upon Key Employees. The Company's success depends on the retention of
its executive officers and other key employees. Competition exists for qualified
personnel and the  Company's  success will depend,  in part,  on attracting  and
retaining such personnel. Failure in these efforts could have a material adverse
effect on the Company's business, financial condition or results of operations.

Shares  Eligible  For Future Sale In  December  1996,  the  Company  completed a
private placement of 3,434,493 units (each unit representing one share of common
stock and a warrant to purchase  one share of common  stock).  The Company  also
granted a warrant to its  placement  agent in the private  placement to purchase
156,000 shares of common stock.  The shares issued in the private  placement and
the underlying shares issuable upon exercise of the warrants were registered for
resale on a Form S-3 registration  statement. In June and July 1997, the Company
completed a private  placement of 2,906,977  units,  each unit consisting of one
share of Common  Stock and one  warrant  to  purchase  one-half  share of Common
Stock. In May 1997, in return for services provided,  the Company granted to Amy
Factor a warrant to purchase 25,000 shares of Common Stock. The shares issued in
the private  placement and the underlying  shares  issuable upon exercise of the

<PAGE>

warrants were  registered for resale on a Form S-3  registration  statement.  In
connection with the Elan transactions in October 1997, Elan purchased  2,727,273
shares of Common  Stock and was  granted a five year  warrant to  purchase  1.75
million shares of common stock.  In January,  1998, the shares issued to Elan as
well as the  487,390  shares  issued to  Schering  (see  "Research  and  Product
Development - Needle-free  Injection  Business") were registered for resale on a
Form S-3 registration  statement. In October, 1997, the Company granted warrants
to purchase  350,000 shares of stock to Robert  Gonnelli in connection  with his
guarantee of an equity investment in the Company. In February, 1998, the Company
granted Raphael,  L.L.C., a management  consulting company which introduced Elan
to the  Company,  a warrant to  purchase  100,000  shares of Common  Stock.  See
"Recent  Developments."  Subsequent  to  year-end,  in June,  1998,  the Company
granted  warrants  to  purchase  130,243  shares of stock to Robert  Gonnelli in
return for services to the Company.  Also  subsequent to year-end,  the warrants
issued in the June and July 1997 private  placement were exercised,  in exchange
for which the Company issued 147,850 new warrants.  Sales of substantial numbers
of common stock in the public  market,  or the  availability  of such shares for
sale,  could adversely  affect the market price for the common stock and make it
more  difficult for the Company to raise funds through  equity  offerings in the
future.

Possible  Adverse Effects on Trading  Market.  The Common Stock is quoted on the
NASDAQ National Market. 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.  In August 1997,  NASDAQ
approved  changes to its  quantitative  and  qualitative  standards  for issuers
listing on NASDAQ. Among the changes are the elimination of the alternative test
for  issuers  failing to meet the  minimum bid price of $1.00 and an increase in
the  quantitative  standards for both the NASDAQ  National Market and the NASDAQ
SmallCap  Market.  The  failure to meet the  maintenance  criteria in the future
could result in the delisting of the Company's 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 the  Company's  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 upon
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.

Possible  Volatility of Stock Price.  The market for the Company's  Common Stock
and  for  the  securities  of  other  early-stage,  small  market-capitalization
companies has been highly  volatile in recent years.  The Company  believes that
factors  such as  quarter-to-quarter  fluctuations  in  financial  results,  new
product  introductions by the Company or its competition,  public announcements,
changing  regulatory  environments,  sales of Common  Stock by certain  existing
shareholders  and substantial  product orders could contribute to the volatility
of  the  price  of  the  Company's   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 the  Company's
Common Stock.

Item 2.     PROPERTIES

The Company's principal offices are located in Portland, Oregon in approximately
23,000 square feet of leased office and manufacturing  space under a lease which
expires in  September  2002.  The  monthly  minimum  lease  obligation  for this
facility is approximately  $15,000. These facilities include the Company's sales
and administration offices and equipment, research and engineering facilities, a
clean room assembly  area,  assembly  line,  testing  facilities and a warehouse
area.


<PAGE>

The Company  leases  additional  warehouse  space totaling  approximately  5,000
square feet for finished  goods storage and shipments to customers.  This lease,
which also expires in September  2002,  has minimum  monthly  lease  obligations
totaling $2,000.

The Company  believes its current  facilities  will be sufficient to support its
operations  for the next 2-3 fiscal years.  As the Company  requires  additional
space to accommodate growth in its sales and manufacturing activities, it is the
Company's  intention  to lease  additional  facilities  adjacent  to or near its
present operations.  The Company believes that, if necessary, it will be able to
obtain  facilities  at rates and under terms  comparable to those of the current
leases.

Item 4.     SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

A Special  Meeting of Stockholders  of Bioject  Medical  Technologies,  Inc. was
convened at 1:00 p.m., on February 20, 1998, at the Company's headquarters, 7620
S.W. Bridgeport Road, Portland, Oregon.

There were  25,368,342  shares of Common  Stock  issued and  outstanding  on the
record date, December 23, 1997.

Of the total shares outstanding on the record date, there were 16,325,537 shares
present  at the  meeting  in person or by proxy,  which is 64.35% of the  Common
Stock entitled to vote, thereby constituting a quorum.

All of the proposals as set forth in the proxy statement for the Special Meeting
were approved. The voting recorded is as follows:

Proposal      #1: The proposal to approve the  exchange of a promissory  note in
              the original  principal  amount of $12.015  million  issued by the
              Company to Elan for approximately  832,000 shares of the Company's
              Series A and Series B  Convertible  Preferred  Stock  received the
              following votes:

                  FOR          AGAINST        ABSTAIN

The closing  sale price on May 29,  1998,  as  reported  on the NASDAQ  National
Market, was $1.688 per share.

The Company has declared no dividends during its history and has no intention of
declaring a dividend in the foreseeable future. As of May 29, 1998 the number of
shareholders of record of the Company's Common Stock was 1,386.

In October 1997, in connection with a joint  development  agreement entered into
with Elan, the Company issued a promissory note to Elan with a principal  amount
of $12.015 million. Upon receiving shareholder approval to convert the note into
the Company's  preferred  stock,  on March 2, 1998, a total of 692,694 shares of
Series A Convertible  Preferred Stock and 134,333 shares of Series B Convertible
Preferred  Stock were issued to Elan (the "Elan  Issuance").

On March 23, 1998, the Company  acquired the assets of Vitajet  Corporation in a
stock-for assets exchange (the "Vitajet  Issuance").  The Company issued 100,000
shares of its common stock in exchange for certain molds, tooling, patent rights
and  customer  lists,  the  value  of  which  totaled  $134,000  at the  date of
acquisition.  The Company is obligated to issue an  additional  60,000 shares in
each of the next three years if certain development milestones are met. Up to an
additional  90,000  shares are also  payable  subject to the  Company  realizing
specified, aggregate levels of incremental revenue over the next three years. 

In April 1998,  warrants  issued in June 1997 were exercised in exchange for the
Company's  commitment to issue additional warrants to purchase 147,850 shares of
the Company's Common Stock (the "Series N Warrants"). The Series N Warrants have
an exercise  price of $1.348 per share and expire on March 31, 2003. The Company
relied upon Rule 506 of Regulation D of the  Securities  Act for the issuance of
the Series N Warrants. The Company relied upon representations and warranties of
the  warrantholders  in addition to its own  information.

The Elan Issuance and Vitajet Issuance were completed  pursuant to an exemption
from registration under Section 4(2) of the Securities Act. In relying upon such
exemption  (i) the Company did not engage in any "general  solicitation," (ii)
the  purchasers  represented  and  the  Company  reasonably  believed  that  the
purchasers had knowledge and  experience in financial and business  matters such
that they were  capable of  evaluating  the merits and risks of the  prospective
investment,  (iii) the  purchasers  were  provided  access to all  necessary and

<PAGE>

adequate  information  to enable the  purchasers to evaluate the financial  risk
inherent in making an  investment,  (iv) the offers were part of an agreement to
establish a joint venture in Elan's case and part of an acquisition agreement in
Vitajet's case and as such was made only to Elan and Vitajet,  respectively, and
(v)  the  purchasers  represented  that  they  were  acquiring  the  shares  for
themselves and not for distribution.

required  to be  expensed  in the  year  paid.  As a  result,  the 1998 net loss
includes a $12 million,  net of minority interest,  one-time charge for acquired
in-process research and development.

The Company has declared no dividends during its history and has no intention of
declaring a dividend in the foreseeable future.

Item 7.     MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
            CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

Operating losses have resulted in an accumulated  deficit of approximately $50.9
million as of March 31, 1998. In fiscal 1996, the Company incurred significantly
increased  costs  associated  with the production and sale of the Biojector 2000
system,  including  sales  and  marketing  efforts,  manufacturing  ramp-up  and
inventory  build-up.  In September 1997, the Company  acquired rights to certain
continuous  blood glucose  monitoring  technology  from Elan  Corporation for an
initial  payment of $15 million and future  milestone  payments  totaling  $15.5
million and royalties on future product  sales.  In fiscal 1998, the $15 million
up front payment was expensed as acquired  in-process  research and development.
In March,  1998, the Company  acquired the rights to the Vitajet  self-injector,
along with certain other assets, in a stock-for-assets  transaction with Vitajet

<PAGE>

Corporation.  The Company's  ability to achieve and sustain  profitability  will
depend in part upon customer  acceptance  of the  Biojector  2000 system and the
continuous  blood glucose  monitoring  system,  sustained  product  performance,
implementing   additional   product  cost  reductions,   successful   commercial
development  of the blood glucose  monitoring  system,  and  attaining  revenues
sufficient to support profitable operations.

In August 1994, Bioject signed an agreement with Health Management,  Inc. (HMI),
granting  HMI  exclusive  rights to  purchase  Bioject's  Needle-Free  Injection
Management  System  (R),  the  Biojector  2000,  for use in the home  healthcare
market.  In return for HMI's commitment to purchase a minimum of 8,000 Biojector
units over the ensuing two years,  the Company granted volume pricing  discounts
to HMI. During the term of the contract,  the selling price of Biojectors to HMI
exceeded their standard cost. During fiscal 1996, the Company sold approximately
4,300  Biojectors  to HMI for total  sales  revenue  including  syringes of $2.2
million. HMI did not place the great majority of these Biojectors with patients,
pending  completion of negotiations  with  pharmaceutical  companies for certain
pricing  concessions for medication to be administered  with the Biojectors.  In
January 1996 HMI requested  that Bioject  suspend  shipments to HMI. In February
1996, the Company learned from HMI's press releases that HMI expected to default
on its debts,  anticipated  taking significant  write-offs  relating to accounts
receivable  and  inventories,  planned  operational  consolidations,  and  would
restate certain prior period financial statements.  In fiscal 1997, although not
obligated  to do so,  the  Company  agreed  to  repurchase  certain  of the  HMI
inventories,  including up to 6,000 Biojector units, for cash and forgiveness of
accounts receivable  totaling $660,000.  The repurchase of these inventories was
at a substantial discount to the original selling price to HMI.

In March 1994, the Company  entered into an agreement with Schering AG, Germany,
for  the  development  of a  self-injection  device  (the  "Self-Injector")  for
delivery of Betaseron (R) to multiple  sclerosis  patients.  During fiscal 1996,
the Company  delivered  the  preproduction  clinical  prototypes to Schering and
worked on finalizing the production  prototype  design.  During fiscal 1997, the
Company  entered  into  a  supply  agreement  with  Schering  AG  and  commenced
activities related to full production of the self-injector.  Schering loaned the
Company a total of $1.6  million to  purchase  molds and  tooling to produce the
product.

In January 1997, the Company  received notice that its contract with Schering AG
would be cancelled. Under provisions of the contract, Schering AG had the option
of canceling the agreement if the FDA required extensive clinical studies beyond
an originally  planned  safety study.  Schering AG received a review letter from
the FDA which  would have  required  Schering  to conduct  additional,  material
clinical studies in order to use  non-traditional  delivery  mechanisms with its
Betaseron  (R) product.  Under terms of the  contract,  Schering was required to
convert its $1.6  million  note due from  Bioject  plus  accrued  interest  into
approximately  487,000 shares of Bioject  common stock at a conversion  price of
$3.50 per share. In addition, Schering was obligated to pay Bioject for the cost
of product  ordered  through the date of  cancellation  of the  contract,  which
payment was made in June 1997.

In  January  1995,  the  Company  signed  a  joint  development  agreement  with
Hoffmann-La  Roche to  develop  proprietary  drug  delivery  systems  for  Roche
products.  The agreement  provides for Bioject to develop,  manufacture and sell
Biojector jet injection drug delivery systems designed to Roche  specifications.
In return,  Bioject has granted Roche exclusive  worldwide  rights to distribute
these  systems  and  their  components  for use  with  certain  Roche  products.
Hoffmann-La Roche Inc. is the United States affiliate of the multinational group
of companies headed by Roche Holding of Basel,  Switzerland,  one of the world's
leading research-intensive healthcare companies. As of the 1995 fiscal year end,
the Company had commenced design of a prototype device and had agreed with Roche
on product  specifications.  During  fiscal  1996,  the  Company  developed  and
delivered  to Roche  preproduction  prototypes  for  testing and  developed  the
clinical  preproduction  prototypes which were delivered to Roche in April 1996.
As of March 31, 1998, the Company and  Hoffmann-LaRoche  were  finalizing  their
submission  to obtain  regulatory  clearance  to market the  product.  Hoffmann-
LaRoche is also gathering  marketing  information which the Company  anticipates
will  lead  to the  signing  of a  supply  agreement  between  the  Company  and
Hoffman-LaRoche.


<PAGE>

In September 1997, the Company and Elan Corporation signed a licensing and joint
development  agreement for the development and  commercialization by the Company
of certain  continuous blood glucose monitoring  technology  licensed from Elan.
Under terms of the agreement,  the Company  borrowed  $12.015  million from Elan
(subsequently  converted to Series A and B convertible preferred stock) and Elan
invested  $2.985  million in a new  subsidiary  of the  Company  created for the
purpose of developing the technology. The Company's new subsidiary,  owned 80.1%
by the  Company  and 19.9% by Elan,  paid  Elan $15  million  for  rights to the
technology  and has  committed  to pay an  additional  $15.5  million to Elan as
future  milestones  are  achieved as well as  royalties  on future  sales of the
product. The new subsidiary will develop the blood glucose monitoring technology
and will seek regulatory clearance for the sale of such product. Such regulatory
clearance is expected in the next 3-4 years with estimated development costs for
the monitoring technology,  exclusive of milestone payments,  estimated to total
at least $10 million.  As part of the agreement,  in October 1997, Elan acquired
2.7 million  shares of common  stock and 1.75  million  warrants to purchase the
Company's  common  stock at $2.50 per share for $3 million.  In  addition,  Elan
agreed to partially fund development of the blood glucose monitoring  technology
up to a total of $4 million  through  the  purchase  of the  Company's  Series C
convertible  preferred stock and through direct purchase of additional  stock in
JV Sub to a maximum of $1 million.  Elan also agreed to fund  development of the
Company's pre-filled jet injection technology through a grant of up to $500,000.

In March 1998,  in a  transaction  with  Vitajet  Corporation,  the Company paid
100,000 shares of its common stock for certain molds, tooling, patent rights and
customer lists,  the value of which totaled $134,400 at the date of acquisition.
In addition to shares  already  paid,  the Company is  obligated to issue 60,000
shares of its common  stock each year in each of the three years  subsequent  to
the acquisition if certain  development  milestones are met. Up to an additional
90,000  shares are also  payable  subject to the  Company  realizing  specified,
aggregate levels of incremental revenue during the three years subsequent to the
Vitajet  acquisition as a result of sales of products acquired from or developed
by Vitajet.

During fiscal 1996,  the Company  implemented  a plan to increase  manufacturing
capacity and refine production  methods to meet anticipated future demand and to
reduce product costs.  For the Biojector 2000, cost reduction  efforts  included
converting  from a two piece to a one piece  housing,  converting  to continuous
process   manufacturing  and  implementing   volume  purchasing   programs  from
suppliers.  For  the  Biojector  syringes,  these  efforts  included  increasing
supplier mold  capacity and  automating  final  assembly and  packaging.  During
fiscal 1997,  the Company's  manufacturing  activities  focused on retesting the
devices  repurchased  from HMI to ensure their  continuing  compliance  with new
product  standards  and  elective  upgrade of certain of these  units to current
version  configuration.   Also  during  fiscal  1997  manufacturing  focused  on
finalizing  product  engineering  and on planning for,  designing and installing
manufacturing lines for the new self injector device syringe manufacturing lines
in  advance  of the  launch  of that  product.  During  fiscal  1998,  having  a
sufficient  inventory of jet injectors  on-hand as a result of the repurchase of
product  from HMI,  the Company  focused its  manufacturing  efforts on refining
manufacturing processes and efficiencies of the disposable syringe manufacturing
line.


<PAGE>

The  Company's  revenues  to date have not been  sufficient  to cover  operating
expenses.  However,  the Company  believes that if its products  achieve  market
acceptance and the volume of sales increases, and its product costs are reduced,
its costs of goods as a percentage  of sales will  decrease and  eventually  the
Company will generate net income. See "Forward Looking Statements" and "Business
- - Risk  Factors."  The level of sales  required to  generate  net income will be
affected by a number of factors including the pricing of the Company's products,
its  ability to attain  efficiencies  that can be  attained  through  volume and
automated   manufacturing,   and  the  impact  of  inflation  on  the  Company's
manufacturing  and other  operating  costs.  There can be no assurance  that the
Company will be able to successfully  implement its manufacturing cost reduction
program  or sell its  products  at prices or in  volumes  sufficient  to achieve
profitability or offset increases in its costs should they occur.

Revenues  and  results of  operations  have  fluctuated  and can be  expected to
continue to  fluctuate  significantly  from  quarter to quarter and from year to
year.  Various  factors  may  affect  quarterly  and  yearly  operating  results
including  (i)  length of time to close  product  sales,  (ii)  customer  budget
cycles, (iii) implementation of cost reduction measures,  (iv) uncertainties and
changes in purchasing due to third party payor  policies and proposals  relating
to  national  healthcare  reform,  (v)  timing  and  amount  of  payments  under
technology  development  agreements,  (vi) timing and cost of development of the
continuous blood glucose monitoring technology,  and (vii) timing of new product
introductions by the Company and its competition.

In the future,  the Company may incur a non-cash charge to compensation  expense
in  connection  with the  issuance  of  100,000  shares of  Common  Stock to the
Company's  Chief  Executive  Officer  and 15,000  shares of common  stock to the
Company's Chief Financial Officer.  Under terms of their employment  agreements,
each will receive the shares of common stock when the Company first achieves two
consecutive  quarters  of positive  earnings  per share.  Upon  issuance of such
shares the Company  will record a non-cash  charge to  compensation  at the fair
market value of the stock on the last day of the quarter in which the shares are
earned.

During the next fiscal year,  the Company will  continue to focus its efforts on
expanding  sales of existing  products,  commencing  manufacture and sale of the
Vitajet,   commencing  manufacture  and  sale  of  the  B4000  Self-Injector  if
regulatory clearance is obtained, reducing the cost of its products,  continuing
development  and  cooperation  in  pursuing  regulatory  clearance  of a 1.5 ml.
injector  for  Hoffmann-La  Roche,   developing  the  blood  glucose  monitoring
technology,  pursuing  additional  alliances with  pharmaceutical  companies and
conserving  its  fiscal  resources.  The  Company  does not expect to report net
income from  operations in fiscal 1999.  See "Forward  Looking  Statements"  and
"Risk Factors."

RESULTS OF OPERATIONS

Product  sales  decreased  from to $3.1 million in fiscal 1996 to $1.3 in fiscal
1997 and  increased  to $1.4  million  in  fiscal  1998.  Sales in  fiscal  1996
consisted of $2.3 million of sales to HMI with the remainder primarily to public
health and flu immunization  clinics.  Sales in fiscal 1997 and 1998,  consisted
primarily of sales to public health and flu immunization clinics.

License and technology fees ranged from $1.2 million in fiscal 1996, to $966,000
in fiscal  1997 and  $500,000  in fiscal  1998.  The  fiscal  1996 and 1997 fees
consisted  principally  of  product  development  revenues  recognized  for work
performed under the Schering and Hoffmann-La Roche  agreements.  The fiscal 1998
fees consisted of revenues for work on the Hoffmann-La Roche project.


<PAGE>

Manufacturing  expense  consists of the costs of product sold and  manufacturing
overhead expense related to excess  manufacturing  capacity.  The total of these
costs varied from $4.8  million in fiscal  1996,  to $1.9 million in fiscal 1997
and $1.7 million in fiscal 1998 due in part to changes in sales and,  therefore,
to changes in the total costs of product  sold.  The  decrease  in expense  from
fiscal 1996 to 1997 and from fiscal 1997 to fiscal 1998  reflects  reductions in
the cost of materials and labor for injectors and syringes as well as reductions
in fixed and variable  manufacturing  overhead expense.  Manufacturing  overhead
totaled $1.67 million, $1.17 million and $981,000 in fiscal 1996, 1997 and 1998,
respectively.

Research and development  expense  decreased from $1.9 million in fiscal 1996 to
$1.6  million  in fiscal  1997 and to  $884,000  in fiscal  1998  (exclusive  of
acquired in-process research and development).  Fiscal 1996 expenditures related
entirely to work performed under the Schering and Hoffmann-La  Roche agreements.
Fiscal 1997  expenditures  related to final design and transfer to manufacturing
of the Schering device and additional  development work on the  Hoffmann-LaRoche
system.  Fiscal 1998  expenditures  related to further  development of the B4000
Self Injector and to pursuing regulatory clearance for the vial adapter product.
See "Risk Factors - Governmental Regulation".

Selling, general and administrative expense totaled, $3.2 million in fiscal 1996
and 1997,  and $3.5 million in fiscal  1998.  During  fiscal 1996 through  1998,
sales and marketing expense remained constant at $1.6 million per year.  General
and  administrative  expense  totaled  $1.6  million in fiscal 1996 and 1997 and
increased to $1.9 million in fiscal 1998  primarily due to  consulting  fees and
certain travel expenditures.

As of September 30, 1997, the Company recorded an expense of $15 million related
to acquired  in-process  research  and  development  expenditures.  Such expense
relates to the blood glucose monitoring  technology that has not yet established
technological   feasibility  and  at  present  has  no  alternate  future  uses.
Accounting rules require that such costs be charged to expense as incurred.  The
Company  believes  that these  research and  development  efforts will result in
commercially  viable  products  within  the  next  three  to  four  years  at an
additional cost to the Company of at least $10 million,  exclusive of additional
milestone payments totaling $15.5 million to Elan.

Interest  expense in fiscal 1998 relates to the $12.015 million debt due to Elan
for the period from  October 15,  1997  through  March 2, 1998 when the note and
accrued  interest was converted to Series A and Series B  convertible  preferred
stock.

Other  income  consists of earnings on  available  cash  balances.  Other income
varied as a result of changes in cash  balances and interest  rates from year to
year.

The  reduction  in net loss in fiscal  1998  resulting  from  minority  interest
allocations  reflects the portion of the joint venture subsidiary loss allocable
to Elan Corporation as a result of its 19.9% ownership in the subsidiary.

LIQUIDITY AND CAPITAL RESOURCES

Since its inception in 1985,  the Company has financed its  operations,  working
capital  needs and capital  expenditures  primarily  from private  placements of
securities,  exercises  of stock  options,  proceeds  received  from its initial
public  offering in 1986,  proceeds  received  from a public  offering of Common
Stock in November 1993, licensing and technology revenues and more recently from
sales of products.  Net  proceeds  received  upon  issuance of  securities  from
inception through March 31, 1998 totaled approximately $56.9 million.
The Company has no long-term debt.

Cash, cash equivalents and marketable  securities  totaled $2.1 million at March
31,  1997 and $1.9  million  at March  31,  1998.  The  decrease  resulted  from
operating losses and capital  expenditures offset in part by net proceeds from a
private placement of common stock and warrants in June and July 1997 and October
1997 and the  issuance of Series A and B  convertible  preferred  stock in March
1998.

Inventories  increased  from $1.7  million at March 31, 1997 to $1.9  million at
March 31, 1998 due to the build-up of syringe inventories to support anticipated
future product sales.

The Company has fixed commitments for facilities rent and equipment leases which
total approximately $250,000 for fiscal 1999.

The Company expended  approximately $1.6 million for capital equipment in fiscal
1997.  Substantially  all  of  these  expenditures  related  to  preparation  of
manufacturing  for the Schering  product  launch.  These  assets  continue to be
carried at their cost on the  Company's  balance  sheet  because  the product is
suitable for other home  injection  applications  which the Company is pursuing.
The Company expended  approximately  $380,000 on capital equipment  additions in
fiscal 1998  approximately  $270,000 of which  related to  Biojector  2000 units
transferred  from inventories to property and equipment to support the Company's
flu season device rental program.

The Company has  assessed  the impact of the Year 2000 issue and has  determined
that costs to upgrade its information and operating  systems are not expected to
be material.

The Company believes that its current cash position, together with cash received
from the exercise of warrants and stock options in April and May 1998,  combined
with  revenues,  other cash  receipts,  proceeds  from issuance of the Company's
Series C preferred  stock and proceeds  from the purchase by Elan of  additional
stock in JV Sub may not be sufficient to fund the Company's  operations  through
the end of fiscal  1999.  The  Company  has  identified  a number  of  potential
financing  sources and is  pursuing  them  aggressively.  See  "Forward  Looking
Statements." Even if the Company is successful in raising additional  financing,
unforeseen  costs and  expenses or lower than  anticipated  cash  receipts  from
product  sales or  research  and  development  activities  could  accelerate  or
increase the financing requirements.  The Company has been successful in raising
additional  financing in the past and  believes  that  sufficient  funds will be
available to fund future operations.  See "Forward Looking Statements." However,
there can be no assurance  that the Company's  efforts will be  successful,  and
there can be no assurance  that such  financing will be available on terms which
are not  significantly  dilutive  to  existing  shareholders.  Failure to obtain
needed additional  capital on terms acceptable to the Company,  or at all, would
significantly  restrict the Company's operations and ability to continue product
development and growth and materially  adversely affect the Company's  business.
The  Company  has no  banking  line of  credit  or other  established  source of
borrowing.  The Company's  independent  accountants have qualified their opinion
with  respect  to  their  audit of the  Company's  1998  consolidated  financial
statements as the result of doubts  concerning the Company's ability to continue
as a going concern in the absence of sufficient additional financing.

   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Board of Directors and Shareholders of Bioject Medical Technologies Inc:

We have audited the accompanying  consolidated balance sheets of Bioject Medical
Technologies Inc. (an Oregon  corporation) and subsidiaries as of March 31, 1998
and 1997, and the related consolidated  statements of operations,  shareholders'
equity and cash flows for each of the three years in the period  ended March 31,
1998.  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  generally   accepted  auditing
standards.  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 Bioject Medical  Technologies
Inc. and  subsidiaries,  as of March 31, 1998 and 1997, and the results of their
operations  and their cash flows for each of the three years in the period ended
March 31, 1998, in conformity with generally accepted accounting principles.

The  accompanying  financial  statements  have been  prepared  assuming that the
Company  will  continue  as a  going  concern.  As  discussed  in  Note 1 to the
financial statements,  the Company has suffered recurring losses from operations
and, at March 31, 1998, has an accumulated  deficit of $---- million that raises
substantial  doubt about the Company's  ability to continue as a going  concern.
Management's  plan in regards to these matters is also  described in Note 1. The
financial  statements do not include any adjustments  relating to recoverability
and  classification  of asset  carrying  amounts  that might  result  should the
Company be unable to continue as a going concern.

               BIOJECT MEDICAL TECHNOLOGIES INC. AND SUBSIDIARIES
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1.     THE COMPANY:

The consolidated  financial statements of Bioject Medical Technologies Inc. (the
"Company" or "Bioject"),  include the accounts of Bioject  Medical  Technologies
Inc. ("BMT"),  an Oregon Corporation,  and its wholly owned subsidiary,  Bioject
Inc., an Oregon Corporation  ("BI"), and its 80.1% owned subsidiary,  Bioject JV
Subsidiary Inc.  ("JV"),  an Oregon  corporation.  All significant  intercompany
transactions have been eliminated. Although Bioject Inc. commenced operations in
1985,  the Company was formed in December  1992 for the purpose of acquiring all
of the capital stock of Bioject Medical Systems Ltd., a Company  organized under
the laws of British Columbia,  Canada, in a stock-for-stock exchange in order to
establish a U.S.  domestic  corporation as the publicly traded parent company of
Bioject Inc. and Bioject Medical  Systems Ltd.  Bioject Medical Systems Ltd. was
terminated in fiscal 1997. Bioject JV Subsidiary Inc. was formed in October 1997
in  connection  with a joint  venture  arrangement  with Elan  Corporation,  plc
("Elan").  All references to the Company include  Bioject  Medical  Technologies
Inc. and its subsidiaries, unless the context requires otherwise.

The  Company  commenced  operations  in 1985  for  the  purpose  of  developing,
manufacturing and distributing a new drug delivery system.  Since its formation,
the Company has been engaged principally in organizational,  financing, research
and development,  and marketing activities.  In the last quarter of fiscal 1993,
the Company launched U.S. distribution of its Biojector 2000 system primarily to
the hospital and large clinic market.  The Company's  products and manufacturing
operations are subject to extensive government regulation,  both in the U.S. and
abroad.  In the U.S., the development,  manufacture,  marketing and promotion of
medical devices is regulated by the Food and Drug  Administration  ("FDA") under
the Federal  Food,  Drug,  and  Cosmetic  Act  ("FFDCA").  In 1987,  the Company
received  clearance  from the FDA under Section  510(k) of the FFDCA to market a
hand-held  CO2-powered jet injection  system. In June 1994, the Company received
clearance  from the FDA under 510(k) to market a version of its  Biojector  2000
system in a configuration  targeted at high volume  injection  applications.  In
October 1996, the Company received 510(k) clearance for a non-needle  disposable
vial access  device.  In March  1997,  the Company  received  additional  510(k)
clearance for certain  enhancements  to its Biojector 2000 system.  On September
30, 1997, the Company  entered into a joint venture  agreement with Elan for the
development and commercialization of certain blood glucose monitoring technology
which  the  Company  licensed  from  Elan  (see  Note  2  regarding  "Accounting
Policies-Research  and Development  and  Licensing/Technology  Revenues").  Such
technology is also subject to  government  regulation in the U.S. by the FDA and
abroad by various agencies.

Since its inception the Company has incurred  operating  losses and at March 31,
1998 has an  accumulated  deficit of  approximately  $51 million.  The Company's
revenues to date have been derived  primarily from licensing and technology fees
for the jet injection  technology  and more recently from sales of the Biojector
2000 system and Biojector  syringes to public health clinics,  flu  immunization
clinics and physicians offices.  Future revenues will depend upon acceptance and
use by  healthcare  providers of the  Company's  jet  injection  technology  and
successful development,  regulatory clearance and market acceptance of its blood
glucose  monitoring  technology.  Uncertainties  over government  regulation and
competition  in  the  healthcare   industry  may  impact   healthcare   provider
expenditures and third party payer reimbursements and, accordingly,  the Company
cannot predict what impact, if any,  subsequent  healthcare reforms and industry
trends  might  have on its  business.  In the  future  the  Company is likely to
require substantial  additional  financing.  Failure to obtain such financing on
favorable terms could adversely affect the Company's business.

The  Company's  revenues  to date have not been  sufficient  to cover  operating
expenses.  However,  the Company  believes that if its products  achieve  market
acceptance and the volume of sales increase,  and its product costs are reduced,
its cost of goods as a  percentage  of sales will  decrease and  eventually  the
Company will  generate net income.  The level of sales  required to generate net
income  will be  affected  by a number of factors  including  the pricing of the
Company's  products,  its  ability to attain  efficiencies  that can be attained
through volume and automated  manufacturing,  and the impact of inflation on the
Company's  manufacturing  and other operating  costs.  There can be no assurance
that the Company will be able to successfully  implement  further  manufacturing
cost  reductions  or sell its  products  at prices or in volumes  sufficient  to
achieve profitability or offset increase in its costs should they occur.


<PAGE>

The Company  believes that its current cash  position,  combined with  revenues,
other cash  receipts,  proceeds from the exercise of stock warrants and options,
proceeds  from the  issuance  of the  Company's  Series C  preferred  stock  and
proceeds  from  the  purchase  by Elan of  additional  stock  in JV,  may not be
sufficient to fund the Company's  operations through the end of fiscal 1999. The
Company has identified a number of potential  financing  sources and is pursuing
them  aggressively.  Even if the  Company is  successful  in raising  additional
financing, unforeseen costs and expenses or lower than anticipated cash receipts
from product sales or research and development  activities  could  accelerate or
increase the financing requirements.  The Company has been successful in raising
additional  financing in the past and  believes  that  sufficient  funds will be
available to fund future operations. However, there can be no assurance that the
Company's  efforts will be  successful,  and there can be no assurance that such
financing  will be  available on terms which are not  significantly  dilutive to
existing  shareholders.  Failure to obtain  needed  additional  capital on terms
acceptable to the Company, or at all, would significantly restrict the Company's
operations and ability to continue product development and growth and materially
adversely affect the Company's business. The financial statements do not include
any  adjustments  relating to the  recoverability  and  classification  of asset
carrying amounts that might result should the Company be unable to continue as a
going concern.

2.     ACCOUNTING POLICIES:

CASH EQUIVALENTS
The Company  considers cash equivalents to consist of short-term,  highly liquid
investments with an original maturity of less than three months.

SECURITIES AVAILABLE FOR SALE
The Company accounts for its investments in marketable  securities in accordance
with Financial  Accounting  Standards  Board  Statement No. 115,  Accounting for
Certain  Investments  in Debt and Equity  Securities  (SFAS  115) as  securities
available for sale. There were no significant realized gains or losses in fiscal
1998, 1997, and 1996.

INVENTORIES
Inventories  are stated at the lower of cost or market.  Cost is determined in a
manner which approximates the first-in,  first out (FIFO) method. Costs utilized
for inventory  valuation  purposes  include labor,  materials and  manufacturing
overhead. Net inventories consist of the following:

                                ==========           ==========


PROPERTY AND EQUIPMENT
For financial statement purposes, depreciation expense on property and equipment
is computed on the straight-line method using the following lives:

   Furniture and Fixtures............................5 years
   Machinery and Equipment...........................7 years
   Computer Equipment................................3 years
   Production Molds..................................5 years

Leasehold  improvements  are  amortized  on the  straight-line  method  over the
shorter of the remaining term of the related lease or the estimated useful lives
of the assets.

Included in machinery and equipment and production molds are molds,  tooling and
production  fixtures  constructed  or  acquired  by the  Company  under a supply
agreement  with  Schering  AG for the  manufacture  and  sale  of a  needle-free
self-injection  system.  The  construction of these assets  commenced in May and
June 1996 and  continued  until  January  1997  when  they were  ready for their
intended use.  Schering  loaned the Company $1.6 million to fund  acquisition of
the  assets,  and  therefore,  in  accordance  with  SFAS 34,  the  Company  has
capitalized $106,000 of interest incurred on this debt.


<PAGE>

OTHER ASSETS
Other assets  include costs incurred for the  application  of patents,  totaling
$503,344 and $455,694 at March 31, 1998 and 1997, respectively.  These costs are
amortized  on a  straight-line  basis  over 17 years.  Accumulated  amortization
totaled  $174,713  and  $144,713  at  March  31,  1998 and  1997,  respectively.
Amortization  expense for the years ended March 31, 1998,  1997 and 1996 totaled
$30,000, $30,000, and $20,000 respectively.

Also  included  in other  assets is the cost of  assets  acquired  from  Vitajet
Corporation  in a stock for  assets  exchange.  In March 1998 the  Company  paid
100,000 shares of its common stock for certain molds, tooling, patent rights and
customer lists,  the value of which totaled  $134,400 at the date of acquisition
and is being  amortized  over 15 years.  In addition to shares already paid, the
Company is  obligated  to issue  60,000  shares of its common stock each year in
each of the three years,  subsequent to the  acquisition if certain  development
milestones are met. Up to an additional 90,000 shares is also payable subject to
the Company realizing specified,  aggregate levels of incremental revenue during
the three years  subsequent to the Vitajet  acquisition  as a result of sales of
products acquired from or developed by Vitajet


ACCOUNTING FOR LONG-LIVED ASSETS
In March 1995, the Financial  Accounting  Standards  Board issued  Statement No.
121,  "Accounting  for the  Impairment of Long-Lived  Assets and for  Long-Lived
Assets To Be Disposed  Of"(SFAS  121),  which requires the Company to review for
impairment  of  its  long-lived  assets  and  certain  identifiable  intangibles
whenever events or changes in circumstances indicate that the carrying amount of
an asset might not be  recoverable.  In certain  situations,  an impairment loss
would be  recognized.  SFAS 121 became  effective for the  Company's  year ended
March 31, 1997. The Company continues to study the implications of SFAS 121 and,
based on its  evaluation,  does not believe that an  adjustment  to the carrying
value of its long-lived assets is necessary.

REVENUE RECOGNITION FOR PRODUCT SALES
The Company records revenue from sales of its products upon shipment.  In fiscal
1998, 1997 and 1996, sales to one customer (different for each period presented)
accounted for 12%, 17% and 75%, respectively, of net sales of products. At March
31, 1998,  1997 and 1996 accounts  receivable  from one customer  (different for
each period presented) accounted for 19%, 62%, and 67%,  respectively,  of total
accounts receivable.

RESEARCH AND DEVELOPMENT AND  LICENSING/TECHNOLOGY  REVENUES  Licensing fees are
recognized as revenue when due and payable.  All licensing fee arrangements have
been on a non-refundable basis and impose no future performance  requirements or
other obligations on the Company.  Product  development revenue is deferred upon
receipt and is recognized as revenue as  qualifying  expenditures  are incurred.
Expenditures for research and development are charged to expense as incurred.

SCHERING  AG.  In March  1994,  the  Company  entered  into a joint  development
agreement  with  Schering  AG,  a  major  pharmaceutical  manufacturer,  for the
development   of   an   application-specific    self   injection   system   (the
"Self-Injector").  Under terms of the agreement, the Company received a $500,000
licensing fee in April 1994 and received partial funding of product  development
expenses on an agreed schedule.  In fiscal 1995, the Company received a total of
$1.1 million from Schering, consisting of $500,000 in licensing fees, which were
recognized  as revenue  during  fiscal  1995,  and  $600,000  of Phase I product
development  revenues,  $444,000 of which were  recognized  as revenue in fiscal
1995. In fiscal 1996, the Company received an additional $660,000 and a total of
$751,000 was recognized as revenue.  In fiscal 1997, the Company  received final
product  development  payments  totaling  $349,500  and  recognized  revenue  of
$414,500.  During fiscal 1997, the Company entered into a supply  agreement with
Schering and commenced  activities  related to preparing  for  production of the
Self Injector.  Schering  loaned the Company a total of $1.6 million to purchase
molds and tooling to produce the product.  In January 1997, the Company received
notice that its contract with Schering would be cancelled.  Under  provisions of


<PAGE>

the  contract,  Schering  had the option of canceling  the  agreement if the FDA
required  extensive  clinical studies beyond an originally planned safety study.
Schering  received  a review  letter  from the FDA  which  would  have  required
Schering  to  conduct  additional  material  clinical  studies  in  order to use
non-traditional  delivery mechanisms with its Betaseron (R) product. Under terms
of the contract, Schering was required to convert its $1.6 million note due from
Bioject  into  approximately  460,000  shares  of  Bioject  common  stock  at  a
conversion  price of $3.50 per share. In addition,  $106,000 of accrued interest
was converted  into  approximately  27,000  shares of Bioject  common stock at a
conversion price of $3.50 per share. Additionally, Schering was obligated to pay
Bioject for the cost of product  ordered through the date of cancellation of the
contract.

HOFFMANN-LA ROCHE. In January 1995, the Company entered into a joint development
agreement with Hoffmann-La Roche, a major pharmaceutical  manufacturer,  for the
development of application  specific-products.  The Company received a licensing
fee  totaling  $500,000  which was  recognized  as revenue in fiscal  1995.  The
Company  is also  receiving  specified  product  development  fees on an  agreed
schedule.  In fiscal 1996, the Company received $900,000,  of which $399,000 was
recognized as revenue.  In fiscal 1997, the Company received $250,000 in product
development fees and recognized revenue of $501,000. In fiscal 1998, the Company
received  $250,000  in  product  development  fees and  recognized  revenues  of
$500,000.

ELAN  CORPORATION.  On September 30, 1997,  the Company  signed a binding letter
agreement (the  "Agreement")  with Elan  Corporation,  plc ("Elan") the goals of
which included the  development  and  commercialization  of Elan's blood glucose
monitoring  technology and a  collaborative  arrangement to further  develop the
Company's  jet injection  technology.  Among  various  terms,  all of which were
determined in arms-length negotiation, the Agreement provides for:

- -    Investment  by Elan of $3 million in Bioject in exchange for  approximately
     2.7 million shares of common stock and a five year warrant to purchase 1.75
     million shares of common stock at $2.50 per share.

- -    Formation  of JV which  is owned  80.1%  by  Bioject  and  19.9% by Elan to
     further develop and commercialize the blood glucose monitoring technology.

- -    Payment  of a $15  million  up  front  fee and  future  milestone  payments
     totaling  $15.5  million and  royalties  on net sales in exchange for North
     American rights to Elan's blood glucose monitoring technology.

- -    The loan of  $12.015  million to Bioject  on a  long-term  promissory  note
     bearing  interest  at 9% per  annum  through  December  31,  1997  and  12%
     thereafter for the purpose of Bioject's  investment in the new subsidiary's
     common stock.

- -    The investment by Elan of $2.985 million in JV's common stock.

- -    The  commitment  by Elan to further  develop the blood  glucose  monitoring
     technology  until the earlier of human clinical  trials,  March 31, 1998 or
     $2.5 million is expended by Elan.

- -    The  submission  to  Bioject's  shareholders  of a proposal  to approve the
     exchange of the  long-term  promissory  note for $10 million  plus  accrued
     interest for the Company's Series A Convertible  Preferred Stock and $2.015
     million  for  Series B  Convertible  Preferred  Stock,  with  the  Series A
     Convertible  Preferred Stock accruing dividends at the rate of 9% per annum
     (compounded  semi-annually)  and the Series B Convertible  Preferred  Stock
     accruing no mandatory dividends.

- -    The  submission  to  Bioject's  shareholders  of a proposal  to approve the
     issuance of up to $4 million of Bioject's  Series C  Convertible  Preferred
     Stock to Elan to provide  Bioject  with  funds to  contribute  toward  JV's
     additional development funding needs.

- -    The  agreement  by Elan to extend the license on a  worldwide  basis if the
     shareholders  approve the exchange of the $12.015  million  promissory note
     for convertible preferred stock.

- -    The agreement by Elan to provide a grant of $500,000 toward  development of
     Bioject's jet injection technology in a pre-filled application.


<PAGE>

Final closing  agreements were signed among the Company,  Elan and the Company's
new  subsidiary on October 15, 1997.  On that date the $3 million  investment in
the Company  was made by Elan and  approximately  2.7  million  shares of common
stock and a warrant  to  purchase  1.75  million  shares at $2.50 per share were
issued. Elan loaned Bioject $12.015 million which Bioject transferred to the new
subsidiary in exchange for 801,000 shares of the subsidiary's common stock. Elan
invested  $2.985 million in the new subsidiary in exchange for 199,000 shares of
the  subsidiary's  common stock.  The new subsidiary paid $15 million to Elan as
its initial payment on the licensing agreement.

On February 20, 1998,  the Company's  shareholders  approved the exchange of the
long-term  promissory  note plus  accrued  interest  for  Series A and  Series B
Convertible  Preferred  Stock and the  issuance to Elan of Series C  Convertible
Preferred  Stock  or  other  similar  convertible  preferred  stock  to  fund JV
development  work.  Accordingly,  on March 2, 1998, a total of 692,694 shares of
Series A Convertible  Preferred Stock and 134,333 shares of Series B Convertible
Preferred Stock were issued to Elan and the promissory note was cancelled.

The  Company  believes  that the license is likely to run for most of the useful
life of the products that may be commercialized  under it. The license itself is
contingent,  on a  country-by-country  basis,  on JV's  diligently  seeking  and
obtaining  regulatory  marketing  clearance  for  licensed  products and on JV's
timely  commercial  launch of the  licensed  products  in  countries  where such
clearance  has been  obtained.  In  addition,  in the event  that a  significant
percentage  of JV's  equity  is  acquired  by any one of a number  of  specified
companies  identified by Elan as actual or potential  competitors,  or any other
entity to which Elan does not consent (which  consent shall not be  unreasonably
withheld in the case of such other,  unspecified companies),  the license may be
immediately terminated at the option of Elan.

As of September 30, 1997, the Company recorded an expense of $15 million related
to acquired  in-process  research  and  development  expenditures.  Such expense
relates to the blood glucose monitoring  technology that has not yet established
technological   feasibility  and  at  present  has  no  alternate  future  uses.
Accounting rules require that such costs be charged to expense as incurred.  The
Company  believes  that these  research and  development  efforts will result in
commercially  viable  products  within  the  next  three  to  four  years  at an
additional cost to the Company of at least $10 million,  exclusive of additional
milestone payments totaling $15.5 million due to Elan.

INCOME TAXES
The Company  accounts for income taxes in accordance with Statement of Financial
Accounting  Standards No. 109, Accounting For Income Taxes (SFAS 109). Under the
liability method specified by SFAS 109,  deferred tax assets and liabilities are
determined based on the temporary  differences  between the financial  statement
and tax bases of assets and liabilities as measured by the enacted tax rates for
the years in which the taxes are  expected to be paid.  At March 31,  1998,  the
Company had total deferred tax assets of approximately  $20 million,  consisting
principally of available net operating loss carryforwards.  No benefit for these
operating losses has been reflected in the accompanying  financial statements as
they do not  satisfy  the  recognition  criteria  set forth in SFAS  109.  Total
deferred tax liabilities were insignificant as of March 31, 1998.

As of March 31, 1998, BMT has net operating loss  carryforwards of approximately
$668,000 available to reduce future federal taxable income, which expire in 2008
through 2013. BI has net operating loss  carryforwards  of  approximately  $38.9
million available to reduce future federal taxable income,  which expire in 2001
through 2013. JV has net operating loss  carryforwards  of  approximately  $12.6
million available to reduce future federal taxable income, which expire in 2013.
Approximately  $3.0 million of BI's  carryforwards were generated as a result of
deductions related to exercises of stock options. When utilized, this portion of
BI's carryforwards,  as tax effected, will be accounted for as a direct increase
to contributed  capital rather than as a reduction of that year's  provision for
income taxes. The principal differences between net operating loss carryforwards
for tax purposes  and the  accumulated  deficit  result from  capitalization  of
certain  start-up costs and deductions  related to the exercise of stock options
for income tax purposes.

USE OF ESTIMATES
The preparation of financial  statements in conformity  with generally  accepted
accounting principles requires management to make estimates and assumptions that
affect  the  reported  amounts  of  assets  and  liabilities  at the date of the
financial  statements and the reported  amounts of revenues and expenses  during
the reporting period. Actual results could differ from those estimates.

RECLASSIFICATIONS

Certain reclassifications have been made to the prior years' expenses to conform
to the current year's presentation.

NET LOSS PER SHARE

Beginning with Fiscal 1998,  basic earnings per shares (EPS) and diluted EPS are
computed  using the  methods  required  by  Statement  of  Financial  Accounting
Standard No. 128,  Earnings per Share (SFAS 128).  Under SFAS 128,  basic EPS is
calculated  using the weighted  average number of common shares  outstanding for
the period.  The computation of diluted  earnings per share includes the effects
of stock options,  warrants and convertible  preferred  stock, if such effect is
dilutive.   Prior  period  amounts  have  been  restated  to  conform  with  the
presentation  requirements of SFAS 128. For the periods  presented,  the Company
has been in a loss position  and,  accordingly  there is no  difference  between
basic EPS and diluted EPS since the common stock  equivalents  and the effect of
convertible   preferred   stock  under  the   "if-converted"   method  would  be
antidilutive.  All  earnings  per  share  amounts  in the  following  table  are
presented to conform to the SFAS 128 requirement:

3.  SEGMENT INFORMATION

The  Company has adopted the  segment  reporting  requirements  of SFAS  No.131,
Disclosures about Segments of an Enterprise and Related Information. At present,
the Company has two reportable  segments which offer different  products and are
managed  separately  because each business  requires  different  technology  and
marketing  strategies.  The  following  sets  forth  the  unaudited  results  of
operations  of the Company for its two segments of  operations  - jet  injection
technology and blood glucose monitoring technology (in thousands):

At March 31, 1998,  no  significant  assets exist  related to the blood  glucose
monitoring   technology  other  than  the  acquired   in-process   research  and
development  which, as discussed in Note 2 above, was required to be written off
at  acquisition.  Accordingly,  the  accompanying  consolidated  balance  sheets
effectively  represent the assets of the jet injection business segment.  In the
future,  certain  proceeds from the sale of equity or issuance of debt by JV may
be  restricted  to JV  operations  only.  To the extent  that they meet  certain
reporting  requirements,  the  separate  assets,  liabilities  and equity of the
parent and its subsidiary will be appropriately disclosed.


4.     401(K) RETIREMENT BENEFIT PLAN:

The  Company  has a  401(k)  Retirement  Benefit  Plan  for its  employees.  All
Employees,  subject to  certain  age and  length of  service  requirements,  are
eligible  to   participate.   The  plan  permits  certain   voluntary   employee
contributions  to be excluded from the employees'  current  taxable income under
provisions  of  the  Internal   Revenue  Code  Section  401(k)  and  regulations
thereunder.  Effective  January 1, 1996, the Company amended the plan to provide
for voluntary employer matches of employee  contributions up to 6% of salary and
for discretionary profit sharing  contributions to all employees.  Such employer
matches and  contributions  may be either in cash or Company  common stock.  For
calendar 1996, the Company agreed to match 25% of employee  contributions  up to
6% of salary with Company stock.  For calendar 1997 and 1998, the Company agreed
to match 37.5% of employee  contributions up to 6% of salary with Company stock.
In fiscal  1998,  1997 and 1996,  the  Company  recorded  an expense of $21,755,
$25,000 and $4,800,  respectively,  related to voluntary  employer matches under
the 401(k)  Plan.  The Board of Directors  has reserved up to 100,000  shares of
common stock for these  voluntary  employer  matches of which 42,631 shares have
been issued and 30,470 shares have been committed through March 31, 1998.

5.     SHAREHOLDERS' EQUITY:

PREFERRED STOCK

The Company has  authorized  10 million  shares of preferred  stock to be issued
from time to time with  such  designations  and  preferences  and other  special
rights and qualifications, limitations and restrictions thereon, as permitted by
law and as fixed  from time to time by  resolution  of the  Board of  Directors.
During fiscal 1998, as described in note 2 regarding the Elan transactions,  the
Company  borrowed  $12.015  million from Elan for the purpose of investing  such
funds in JV. On February  20,  1998,  the  Company's  shareholders  approved the
exchange  of this  debt,  plus  accrued  interest,  for  Series  A and  Series B
convertible  preferred  stock  and  approved  the  future  issuance  of Series C
Convertible  Preferred Stock. At March 31, 1998, the Company had preferred stock
authorized and outstanding as follows:

Series A  Convertible  Preferred  Stock.  Series A preferred  stock  accumulates
dividends  at 9% per annum,  compounded  semi-annually,  payable  in  additional
Series A Convertible  Preferred  Stock.  Each original share may be converted at
the holder's  election into 10 shares of common stock and may be redeemed at the
Company's election on the third,  fourth and fifth  anniversaries of issuance if
the  Company's  common  stock is greater than or equal to $2.25 per share by the
payment to the holder of an amount  equal to the  original  issuance  price plus
accumulated  dividends  thereon.  If not  earlier  converted  or  redeemed,  the
original  issuance  price of the Series A  Convertible  Stock  plus  accumulated
dividends  thereon must be converted into common stock of the Company on October
15, 2004 at the lesser of $1.50 or 80% of the  average of the closing  prices of
common stock for the ten trading  days ending on October 13, 2004.  The Series A
Convertible Preferred Stock has preference in liquidation to the common stock of
the Company. A total of 692,694 shares with an original issuance value of $15.00
per share has been issued.

Series B Convertible  Preferred  Stock.  Series B preferred stock has all of the
rights and  preferences of the Series A Convertible  Preferred  Stock  including
optional conversion, optional redemption and mandatory conversion except that it
bears no mandatory  dividend  but  participates  in dividends  pro rata with the
common shareholders. A total of 134,333 shares of Series B Convertible Preferred
Stock with an original issuance value of $15.00 per share have been issued.

Series C Convertible  Stock.  Series C preferred stock has all of the rights and
preferences  of the Series A  Convertible  Preferred  Stock  including  optional
conversion, optional redemption and mandatory conversion except that it bears no
mandatory  dividend  but  participates  in  dividends  pro rata with the  common
shareholders.  Its original issuance price will be equal to market value, if and
when such shares are issued.  Proceeds are  restricted  for use in the JV. There
are no shares issued and outstanding at March 31, 1998.

Inherent dividend. As described above, under certain conditions the Series A and
Series B Convertible  Preferred  Stock is  convertible  into common stock of the
Company at a price which  represents  a 20%  discount to its par value of $15.00
per share.  The value of this inherent  dividend has been recorded as a discount
to preferred  stock and an increase to common  stock  totaling $3 million and is

COMMON STOCK

Holders of common  stock are  entitled to one vote for each share of record held
on all  matters  to be voted on by  shareholders.  No shares  have  been  issued
subject to assessment,  and there are no preemptive or conversion  rights and no
provision  for  redemption,  purchase or  cancellation,  surrender or sinking or
purchase  funds.  Holders of common  stock are not  entitled to  cumulate  their

have been  reserved  by the  Board of  Directors  for  issuance  to 401(k)  plan
participants  (see note 4) of which  42,631  shares  have been issued and 30,470
shares are committed to be issued through March 31, 1998.

STOCK OPTIONS

Options may be granted to  directors,  officers and  employees of the Company by
the Board of Directors under terms of the Bioject Medical Technologies Inc. 1992
Stock  Incentive  Plan  (the  "Plan"),  which  was  approved  by  the  Company's
shareholders  on November 20, 1992 and adopted by the Board  effective  December
17, 1992. Under the terms of the Plan,  eligible employees may receive statutory
and nonstatutory stock options,  stock bonuses and stock appreciation rights for
purchase  of shares of the  Company's  common  stock at prices  and  vesting  as
determined  by a committee  of the Board.  Except for  options  whose terms were
extended,  options  granted under a prior plan maintain  their  previous  option
price, vesting and expiration dates. As amended in fiscal 1995, a total of up to
3,000,000 shares of the Company's common stock, including options outstanding at
the date of initial  shareholder  approval of the Plan, may be granted under the
Plan. Options outstanding at March 31, 1998 expire through April 2006.

In October 1995, the Financial  Accounting  Standards Board issued Statement No.
123,  Accounting for Stock-Based  Compensation  (SFAS 123), which  establishes a
fair  value-based  method of accounting for stock-based  compensation  plans and
requires additional  disclosures for those companies that elect not to adopt the
new method of  accounting.  The  Company  has elected to continue to account for
stock  options  under  APB  Opinion  No.  25,  Accounting  for  Stock  Issued to
Employees.  However, as prescribed by SFAS 123 the Company has computed, for pro
forma disclosure purposes,  the value of all options granted during fiscal 1998,
1997 and 1996 using the  Black-Scholes  option-  pricing model and the following
weighted average assumptions:

                                        Year ended March 31,
                                    1998       1997       1996
                                   ------     ------     ------
  Risk-free interest rate            6%         6%          6%
  Expected dividend yield            0%         0%          0%
  Expected life                    1.5 yrs.  1.5 yrs.    1.5 yrs.
  Expected volatility                78%        47%         47%

The total value of options  granted  during fiscal 1998,  1997 and 1996 would be
amortized on a pro forma basis over the vesting  period of the options.  Options
generally vest equally over three years.  If the Company had accounted for these
plans in accordance with SFAS 123, the Company's net loss and net loss per share
would have  increased  as  reflected  in the  following  pro forma  amounts  (in
thousands of $):

                                      Year ended March 31,
                                    1998      1997      1996
                                   ------    ------    ------
Net loss:
  As reported                    $(16,630)  $(4,296)  $(5,431)
  Pro forma                      $(16,969)  $(4,480)  $(5,541)
Net loss per share:
  As reported                     $(0.72)   $(0.26)   $(0.39)
  Pro forma                       $(0.73)   $(0.27)   $(0.39)

The above determination of proforma expense has been calculated  consistent with
SFAS 123 which does not take into  consideration  limitations on  exercisability
and transferability  imposed by the Company's Stock Incentive Plan. Further, the
valuation  model is heavily  weighted  to stock  price  volatility,  even with a
declining  stock price,  which tends to increase  calculated  value.  The actual
value, if any, and,  therefore,  imputed proforma expense will vary based on the
exercise date and the market price of the related common stock when sold.

                                  WARRANT H001

THIS WARRANT AND THE  SECURITIES  ISSUABLE  UPON  EXERCISE  HEREOF HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE
LAWS,  AND NO INTEREST  THEREIN  MAY BE SOLD,  DISTRIBUTED,  ASSIGNED,  OFFERED,
PLEDGED OR  OTHERWISE  TRANSFERRED  UNLESS  THERE IS AN  EFFECTIVE  REGISTRATION
STATEMENT UNDER SUCH ACT AND APPLICABLE  STATE SECURITIES LAWS COVERING ANY SUCH
TRANSACTION OR SUCH TRANSACTION IS EXEMPT FROM THE REGISTRATION  REQUIREMENTS OF
SUCH ACT AND LAWS,  SUCH  COMPLIANCE,  AT THE OPTION OF THE  CORPORATION,  TO BE
EVIDENCED BY AN OPINION OF  WARRANTHOLDER'S  COUNSEL,  IN FORM ACCEPTABLE TO THE
CORPORATION, THAT NO VIOLATION OF SUCH REGISTRATION PROVISIONS WOULD RESULT FROM
ANY PROPOSED TRANSFER OR ASSIGNMENT.

                    SERIES "H" COMMON STOCK PURCHASE WARRANT

                       Bioject Medical Technologies Inc.

THIS  CERTIFIES  that for  good  and  valuable  consideration  received,  Robert
Gonnelli, a(n) individual or registered assigns, is entitled, upon the terms and
subject to the conditions hereinafter set forth, to acquire from Bioject Medical
Technologies Inc., an Oregon corporation (the "Corporation") up to 200,000 fully
paid and  nonassessable  shares of  common  stock,  without  par  value,  of the
Corporation  ("Warrant  Stock")  at a purchase  price per share  (the  "Exercise
Price") of $1.00.

1.       Term of Warrant

Subject to the terms and  conditions  set forth  herein,  this Warrant  shall be
exercisable,  in whole or from  time to time  part,  at any time on or after the
date hereof and at or prior to 11:59 p.m.,  Pacific  Standard Time, on September
21, 2002 (the "Expiration Time").

2.       Exercise of Warrant

The  purchase  rights  represented  by  this  Warrant  are  exercisable  by  the
registered holder hereof, in whole or in part, at any time and from time to time
at or prior to the  Expiration  Time by the  surrender  of this  Warrant and the
Notice of  Exercise  form  attached  hereto  duly  executed to the office of the
Corporation at 7620 S.W. Bridgeport Road, Portland,  Oregon 97224 (or such other
office or agency of the  Corporation as it may designate by notice in writing to
the  registered  holder  hereof at the address of such holder  appearing  on the
books of the Corporation), and upon payment of the Exercise Price for the shares
thereby purchased (by cash or by check or bank draft payable to the order of the
Corporation or by  cancellation of indebtedness of the Corporation to the holder
hereof, if any, at the time of exercise in an amount equal to the purchase price
of the shares thereby purchased);  whereupon the holder of this Warrant shall be
entitled to receive  from the  Corporation  a stock  certificate  in proper form
representing the number of shares of Warrant Stock so purchased.

3.       Issuance of Shares; No Fractional Shares of Scrip

Certificates  for shares  purchased  hereunder  shall be delivered to the holder
hereof by the Corporation's transfer agent at the Corporation's expense within a
reasonable  time after the date on which this Warrant shall have been  exercised
in accordance with the terms hereof.  Each  certificate so delivered shall be in
such  denominations  as may be  requested  by the  holder  hereof  and  shall be
registered in the name of such holder or, subject to applicable laws, other name
as shall be requested by such holder.  If, upon exercise of this Warrant,  fewer
than all of the shares of Warrant Stock  evidenced by this Warrant are purchased
prior to the Expiration Time, one or more new warrants substantially in the form
of, and on the terms in, this Warrant will be issued for the remaining number of
shares of  Warrant  Stock not  purchased  upon  exercise  of this  Warrant.  The
Corporation  hereby  represents  and warrants  that all shares of Warrant  Stock
which may be issued upon the exercise of this Warrant will,  upon such exercise,
be duly and validly authorized and issued, fully paid and nonassessable and free
from all taxes, liens and charges in respect of the issuance thereof (other than
liens or charges  created by or imposed  upon the holder of the Warrant  Stock).

<PAGE>

The  Corporation  agrees that the shares so issued  shall be and be deemed to be
issued to such  holder  as the  record  owner of such  shares as of the close of
business  on the date on which  this  Warrant  shall have been  surrendered  for
exercise in  accordance  with the terms hereof.  No  fractional  shares or scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant. With respect to any fraction of a share called for upon the exercise of
this Warrant,  an amount equal to such  fraction  multiplied by the then current
price at which each share may be  purchased  hereunder  shall be paid in cash to
the holder of this Warrant.

4.       Charges, Taxes and Expenses

Issuance of  certificates  for shares of Warrant Stock upon the exercise of this
Warrant  shall be made  without  charge to the  holder  hereof  for any issue or
transfer  tax or other  incidental  expense in respect of the  issuance  of such
certificate,  all of which taxes and expenses shall be paid by the  Corporation,
and such certificates  shall be issued in the name of the holder of this Warrant
or in such  name or names as may be  directed  by the  holder  of this  Warrant;
provided,  however,  that in the event  certificates for shares of Warrant Stock
are to be issued in a name other  than the name of the  holder of this  Warrant,
this  Warrant  when  surrendered  for  exercise  shall  be  accompanied  by  the
Assignment Form attached hereto duly executed by the holder hereof.

5.       No Rights as Shareholders

This  Warrant does not entitle the holder  hereof to any voting  rights or other
rights as a shareholder of the Corporation prior to the exercise hereof.

6.       Registration Rights

The  Warrant  Stock  purchasable  upon  exercise  of this  Warrant  has not been
registered  under the  Securities  Act of 1933 or any state securities law. The
Corporation  shall have no obligation to register such Warrant Stock for resale.
The foregoing  notwithstanding,  any obligation undertaken by the Corporation to
register the Warrant Stock shall be limited to the Corporation's use of its best
efforts to do so, and in no event shall the  Corporation  be required to file or
maintain the effectiveness of a registration statement on Form S-1.

7.       Exchange and Registry of Warrant

This Warrant is exchangeable, upon the surrender hereof by the registered holder
at the above-mentioned office or agency of the Corporation, for a new Warrant of
like tenor and dated as of such exchange.  The Corporation shall maintain at the
above-mentioned  office or agency a registry showing the name and address of the
registered holder of this Warrant. This Warrant may be surrendered for exchange,
transfer or exercise,  in accordance with its terms, at such office or agency of
the Corporation,  and the Corporation shall be entitled to rely in all respects,
prior to written notice to the contrary, upon such registry.

8.       Loss, Theft, Destruction or Mutilation of Warrant

Upon receipt by the Corporation of evidence reasonably satisfactory to it of the
loss,  theft,  destruction  or mutilation of this Warrant,  and in case of loss,
theft or destruction of indemnity or security reasonably satisfactory to it, and
upon  reimbursement  to the  Corporation of all reasonable  expenses  incidental
thereto, and upon surrender and cancellation of this Warrant, if mutilated,  the
Corporation  will make and  deliver a new  Warrant of like tenor and dated as of
such cancellation, in lieu of this Warrant.

9.       Saturdays, Sundays and Holidays

If the last or appointed  day for the taking of any action or the  expiration of
any right required or granted herein shall be a Saturday or a Sunday or shall be
a legal holiday, then such action may be taken or such right may be exercised on
the next succeeding day not a Saturday, Sunday or legal holiday.

<PAGE>

10.      Merger, Sale of Assets, Etc.

If at any time the Corporation proposes to merge or consolidate with or into any
other  corporation,  effect  any  reorganization,  or  sell  or  convey  all  or
substantially  all of its assets to any other  entity,  then,  as a condition of
such reorganization,  consolidation, merger, sale or conveyance, the Corporation
or its successor,  as the case may be, shall enter into a supplemental agreement
to make lawful and adequate provision whereby the holder shall have the right to
receive,  upon exercise of the Warrant, the kind and amount of equity securities
which would have been received upon such reorganization,  consolidation, merger,
sale or  conveyance  by a holder of a number of shares of common  stock equal to
the number of shares issuable upon exercise of the Warrant  immediately prior to
such reorganization,  consolidation, merger, sale or conveyance. If the property
to  be  received  upon  such  reorganization,  consolidation,  merger,  sale  or
conveyance is not equity  securities,  the Corporation  shall give the holder of
this Warrant  fifteen (15) business  days prior  written  notice of the proposed
effective date of such  transaction,  and if this Warrant has not been exercised
by or on the effective date of such transaction, it shall terminate.

11.      Subdivision, Combination, Reclassification, Conversion, Etc.

If  the   Corporation   at  any  time  shall,   by   subdivision,   combination,
reclassification  of securities or otherwise,  change the Warrant Stock into the
same or a different  number of securities of any class or classes,  this Warrant
shall  thereafter  entitle  the  holder  to  acquire  such  number  and  kind of
securities as would have been issuable in respect of the Warrant Stock (or other
securities  which  were  subject  to the  purchase  rights  under  this  Warrant
immediately prior to such subdivision,  combination,  reclassification  or other
change) as the result of such change if this Warrant had been  exercised in full
for cash immediately prior to such change. The Exercise Price hereunder shall be
adjusted if and to the extent  necessary to reflect such change.  If the Warrant
Stock or other  securities  issuable  upon  exercise  hereof are  subdivided  or
combined into a greater or smaller number of shares of such security, the number
of shares issuable hereunder shall be proportionately increased or decreased, as
the case may be, and the  Exercise  Price  shall be  proportionately  reduced or
increased,  as the case may be, in both cases  according  to the ratio which the
total number of shares of such security to be outstanding immediately after such
even  bears  to  the  total  number  of  shares  of  such  security  outstanding
immediately  prior to such event.  The Corporation  shall give the holder prompt
written notice of any change in the type of securities issuable  hereunder,  any
adjustment of the Exercise Price for the securities issuable hereunder,  and any
increase or decrease in the number of shares issuable hereunder.

12.      Transferability; Compliance with Securities Laws

(a)  This Warrant may not be transferred or assigned in whole or in part without
     compliance  with all applicable  federal and state  securities  laws by the
     transferor   and   transferee   (including   the  delivery  of   investment
     representation  letters and legal opinions  reasonably  satisfactory to the
     Corporation,  if requested by the Corporation).  Subject such restrictions,
     prior to the  Expiration  Time,  this Warrant and all rights  hereunder are
     transferable  by the holder  hereof,  in whole or in part, at the office or
     agency  of the  Corporation  referred  to in  Section  1  hereof.  Any such
     transfer  shall  be made  in  person  or by the  holder's  duly  authorized
     attorney,  upon surrender of this Warrant together with the Assignment Form
     attached hereto properly endorsed.

(b)  The Holder of this Warrant,  by acceptance  hereof,  acknowledges that this
     Warrant and the  Warrant  Stock  issuable  upon  exercise  hereof are being
     acquired  solely for the  holder's own account and not as a nominee for any
     other party, and for investment,  and that the holder will not offer,  sell
     or otherwise  dispose of this Warrant or any shares of Warrant  Stock to be
     issued upon exercise hereof except under circumstances that will not result
     in a violation  of the  Securities  Act of 1933,  as amended,  or any state
     securities  laws.  Upon  exercise of this  Warrant,  the holder  shall,  if
     requested by the Corporation, confirm in writing, in a form satisfactory to
     the  Corporation,  that the shares of Warrant  Stock so purchased are being
     acquired solely for holder's own account and not as a nominee for any other
     party, for investment, and not with a view toward distribution or resale.

<PAGE>

(c)  Except as contemplated in the Registration  Rights  Agreement,  the Warrant
     Stock has not been and will not be registered  under the  Securities Act of
     1933, as amended,  and this Warrant may not be exercised  except by (i) the
     original  purchaser  of  this  Warrant  from  the  Corporation  or  (ii) an
     "accredited investor" as defined in Rule 501(a) under the Securities Act of
     1933, as amended. Each certificate  representing the Warrant Stock or other
     securities  issued in respect of the  Warrant  Stock upon any stock  split,
     stock dividend,  recapitalization,  merger, consolidation or similar event,
     shall be stamped or otherwise imprinted with a legend  substantially in the
     following  form  (in  addition  to any  legend  required  under  applicable
     securities laws):

THE SECURITIES  REPRESENTED  HEREBY HAVE NOT BEEN REGISTERED UNDER UNITED STATES
FEDERAL  OR STATE  SECURITIES  LAWS AND MAY NOT BE  OFFERED  FOR  SALE,  SOLD OR
OTHERWISE TRANSFERRED OR ASSIGNED FOR VALUE, DIRECTLY OR INDIRECTLY, NOR MAY THE
SECURITIES BE TRANSFERRED ON THE BOOKS OF THE CORPORATION,  WITHOUT REGISTRATION
OF  SUCH  SECURITIES  UNDER  ALL  APPLICABLE  UNITED  STATES  FEDERAL  OR  STATE
SECURITIES  LAWS OR COMPLIANCE  WITH AN  APPLICABLE  EXEMPTION  THEREFROM,  SUCH
COMPLIANCE,  AT THE OPTION OF THE CORPORATION,  TO BE EVIDENCED BY AN OPINION OF
SHAREHOLDER'S COUNSEL, IN FORM ACCEPTABLE TO THE CORPORATION,  THAT NO VIOLATION
OF SUCH  REGISTRATION  PROVISIONS  WOULD  RESULT FROM ANY  PROPOSED  TRANSFER OR
ASSIGNMENT.

13.      Representations and Warranties

The Corporation hereby represents and warrants to the holder hereof that:

(a)  during the period this Warrant is outstanding, the Corporation will reserve
     from its authorized and unissued common stock a sufficient number of shares
     to provide  for the  issuance  of Warrant  Stock upon the  exercise of this
     Warrant;

(b)  the  issuance  of this  Warrant  shall  constitute  full  authority  to the

     certificates to execute and issue the necessary certificates for the shares
     of Warrant Stock issuable upon exercise of this Warrant;

(c)  the  Corporation has all requisite legal and corporate power to execute and
     deliver this  Warrant,  to sell and issue the Warrant Stock  hereunder,  to
     issue the common stock  issuable  upon exercise of the Warrant Stock and to
     carry out and perform its obligations under the terms of this Warrant; and

     shareholders  necessary  for the  authorization,  execution,  delivery  and
     performance of this Warrant by the Corporation,  the  authorization,  sale,
     issuance  and  delivery of the  Warrant  Stock,  the grant of  registration
     rights  as  provided  herein  and  the  performance  of  the  Corporation's
     obligations hereunder has been taken;

(e)  the Warrant  Stock,  when issued in compliance  with the provisions of this
     Warrant and the  Corporation's  Articles of  Incorporation  (as they may be
     amended from time to time (the "Articles")),  will be validly issued, fully
     paid and  nonassessable,  and free of all taxes, liens or encumbrances with
     respect to the issue  thereof,  and will be issued in  compliance  with all
     applicable federal and state securities laws; and

(f)  the  issuance  of the Warrant  Stock will not be subject to any  preemptive
     rights, rights of first refusal or similar rights.

The  Corporation  will  not,  by  amendment  of  its  Articles  or  through  any
reorganization,  recapitalization,  transfer of assets,  consolidation,  merger,
dissolution,  issue or sale of securities or any other action,  avoid or seek to
avoid  the  observance  or  performance  of any of the terms to be  observed  or
performed  hereunder  by the  Corporation,  but will at all times in good  faith
assist in the  carrying  out of all the  provisions  of this  Warrant and in the
taking of all such action as may be necessary or appropriate in order to protect
the rights of the holder of the Warrant against impairment.

representing the number of shares of Warrant Stock so purchased.

3.       Issuance of Shares; No Fractional Shares of Scrip

representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant. With respect to any fraction of a share called for upon the exercise of
this Warrant,  an amount equal to such  fraction  multiplied by the then current
price at which each share may be  purchased  hereunder  shall be paid in cash to
the holder of this Warrant.

4.       Charges, Taxes and Expenses

Issuance of  certificates  for shares of Warrant Stock upon the exercise of this
Warrant  shall be made  without  charge to the  holder  hereof  for any issue or

and such certificates  shall be issued in the name of the holder of this Warrant
or in such  name or names as may be  directed  by the  holder  of this  Warrant;
provided,  however,  that in the event  certificates for shares of Warrant Stock

this  Warrant  when  surrendered  for  exercise  shall  be  accompanied  by  the
Assignment Form attached hereto duly executed by the holder hereof.

5.       No Rights as Shareholders

This  Warrant does not entitle the holder  hereof to any voting  rights or other
rights as a shareholder of the Corporation prior to the exercise hereof.

6.       Registration Rights

The  Warrant  Stock  purchasable  upon  exercise  of this  Warrant  has not been
registered  under the  Securities  Act of 1933 or any state securities law. The
Corporation  shall have no obligation to register such Warrant Stock for resale.
The foregoing  notwithstanding,  any obligation undertaken by the Corporation to
register the Warrant Stock shall be limited to the Corporation's use of its best
efforts to do so, and in no event shall the  Corporation  be required to file or
maintain the effectiveness of a registration statement on Form S-1.

at the above-mentioned office or agency of the Corporation, for a new Warrant of
like tenor and dated as of such exchange.  The Corporation shall maintain at the

registered holder of this Warrant. This Warrant may be surrendered for exchange,

the Corporation,  and the Corporation shall be entitled to rely in all respects,
prior to written notice to the contrary, upon such registry.

the next succeeding day not a Saturday, Sunday or legal holiday.

<PAGE>

10.      Merger, Sale of Assets, Etc.

If at any time the Corporation proposes to merge or consolidate with or into any
other  corporation,  effect  any  reorganization,  or  sell  or  convey  all  or
substantially  all of its assets to any other  entity,  then,  as a condition of
such reorganization,  consolidation, merger, sale or conveyance, the Corporation
or its successor,  as the case may be, shall enter into a supplemental agreement
to make lawful and adequate provision whereby the holder shall have the right to
receive,  upon exercise of the Warrant, the kind and amount of equity securities
which would have been received upon such reorganization,  consolidation, merger,
sale or  conveyance  by a holder of a number of shares of common  stock equal to
the number of shares issuable upon exercise of the Warrant  immediately prior to
such reorganization,  consolidation, merger, sale or conveyance. If the property
to  be  received  upon  such  reorganization,  consolidation,  merger,  sale  or
conveyance is not equity  securities,  the Corporation  shall give the holder of
this Warrant  fifteen (15) business  days prior  written  notice of the proposed
effective date of such  transaction,  and if this Warrant has not been exercised
by or on the effective date of such transaction, it shall terminate.

11.      Subdivision, Combination, Reclassification, Conversion, Etc.

If  the   Corporation   at  any  time  shall,   by   subdivision,   combination,
reclassification  of securities or otherwise,  change the Warrant Stock into the
same or a different  number of securities of any class or classes,  this Warrant
shall  thereafter  entitle  the  holder  to  acquire  such  number  and  kind of
securities as would have been issuable in respect of the Warrant Stock (or other
securities  which  were  subject  to the  purchase  rights  under  this  Warrant
immediately prior to such subdivision,  combination,  reclassification  or other
change) as the result of such change if this Warrant had been  exercised in full
for cash immediately prior to such change. The Exercise Price hereunder shall be
adjusted if and to the extent  necessary to reflect such change.  If the Warrant
Stock or other  securities  issuable  upon  exercise  hereof are  subdivided  or
combined into a greater or smaller number of shares of such security, the number
of shares issuable hereunder shall be proportionately increased or decreased, as
the case may be, and the  Exercise  Price  shall be  proportionately  reduced or
increased,  as the case may be, in both cases  according  to the ratio which the
total number of shares of such security to be outstanding immediately after such
even  bears  to  the  total  number  of  shares  of  such  security  outstanding
immediately  prior to such event.  The Corporation  shall give the holder prompt
written notice of any change in the type of securities issuable  hereunder,  any
adjustment of the Exercise Price for the securities issuable hereunder,  and any
increase or decrease in the number of shares issuable hereunder.

12.      Transferability; Compliance with Securities Laws

(a)  This Warrant may not be transferred or assigned in whole or in part without
     compliance  with all applicable  federal and state  securities  laws by the
     transferor   and   transferee   (including   the  delivery  of   investment
     representation  letters and legal opinions  reasonably  satisfactory to the
     Corporation,  if requested by the Corporation).  Subject such restrictions,
     prior to the  Expiration  Time,  this Warrant and all rights  hereunder are
     transferable  by the holder  hereof,  in whole or in part, at the office or
     agency  of the  Corporation  referred  to in  Section  1  hereof.  Any such
     transfer  shall  be made  in  person  or by the  holder's  duly  authorized
     attorney,  upon surrender of this Warrant together with the Assignment Form
     attached hereto properly endorsed.

(b)  The Holder of this Warrant,  by acceptance  hereof,  acknowledges that this
     Warrant and the  Warrant  Stock  issuable  upon  exercise  hereof are being
     acquired  solely for the  holder's own account and not as a nominee for any
     other party, and for investment,  and that the holder will not offer,  sell
     or otherwise  dispose of this Warrant or any shares of Warrant  Stock to be
     issued upon exercise hereof except under circumstances that will not result
     in a violation  of the  Securities  Act of 1933,  as amended,  or any state
     securities  laws.  Upon  exercise of this  Warrant,  the holder  shall,  if
     requested by the Corporation, confirm in writing, in a form satisfactory to
     the  Corporation,  that the shares of Warrant  Stock so purchased are being
     acquired solely for holder's own account and not as a nominee for any other
     party, for investment, and not with a view toward distribution or resale.

<PAGE>

(c)  Except as contemplated in the Registration  Rights  Agreement,  the Warrant
     Stock has not been and will not be registered  under the  Securities Act of
     1933, as amended,  and this Warrant may not be exercised  except by (i) the
     original  purchaser  of  this  Warrant  from  the  Corporation  or  (ii) an
     "accredited investor" as defined in Rule 501(a) under the Securities Act of
     1933, as amended. Each certificate  representing the Warrant Stock or other
     securities  issued in respect of the  Warrant  Stock upon any stock  split,
     stock dividend,  recapitalization,  merger, consolidation or similar event,
     shall be stamped or otherwise imprinted with a legend  substantially in the
     following  form  (in  addition  to any  legend  required  under  applicable
     securities laws):

THE SECURITIES  REPRESENTED  HEREBY HAVE NOT BEEN REGISTERED UNDER UNITED STATES
FEDERAL  OR STATE  SECURITIES  LAWS AND MAY NOT BE  OFFERED  FOR  SALE,  SOLD OR
OTHERWISE TRANSFERRED OR ASSIGNED FOR VALUE, DIRECTLY OR INDIRECTLY, NOR MAY THE
SECURITIES BE TRANSFERRED ON THE BOOKS OF THE CORPORATION,  WITHOUT REGISTRATION
OF  SUCH  SECURITIES  UNDER  ALL  APPLICABLE  UNITED  STATES  FEDERAL  OR  STATE
SECURITIES  LAWS OR COMPLIANCE  WITH AN  APPLICABLE  EXEMPTION  THEREFROM,  SUCH
COMPLIANCE,  AT THE OPTION OF THE CORPORATION,  TO BE EVIDENCED BY AN OPINION OF
SHAREHOLDER'S COUNSEL, IN FORM ACCEPTABLE TO THE CORPORATION,  THAT NO VIOLATION
OF SUCH  REGISTRATION  PROVISIONS  WOULD  RESULT FROM ANY  PROPOSED  TRANSFER OR
ASSIGNMENT.

10.      Merger, Sale of Assets, Etc.

If at any time the Corporation proposes to merge or consolidate with or into any
other  corporation,  effect  any  reorganization,  or  sell  or  convey  all  or
substantially  all of its assets to any other  entity,  then,  as a condition of
such reorganization,  consolidation, merger, sale or conveyance, the Corporation
or its successor,  as the case may be, shall enter into a supplemental agreement
to make lawful and adequate provision whereby the holder shall have the right to
receive,  upon exercise of the Warrant, the kind and amount of equity securities
which would have been received upon such reorganization,  consolidation, merger,
sale or  conveyance  by a holder of a number of shares of common  stock equal to
the number of shares issuable upon exercise of the Warrant  immediately prior to
such reorganization,  consolidation, merger, sale or conveyance. If the property
to  be  received  upon  such  reorganization,  consolidation,  merger,  sale  or
conveyance is not equity  securities,  the Corporation  shall give the holder of
this Warrant  fifteen (15) business  days prior  written  notice of the proposed

If  the   Corporation   at  any  time  shall,   by   subdivision,   combination,
reclassification  of securities or otherwise,  change the Warrant Stock into the
same or a different  number of securities of any class or classes,  this Warrant
shall  thereafter  entitle  the  holder  to  acquire  such  number  and  kind of
securities as would have been issuable in respect of the Warrant Stock (or other
securities  which  were  subject  to the  purchase  rights  under  this  Warrant
immediately prior to such subdivision,  combination,  reclassification  or other
change) as the result of such change if this Warrant had been  exercised in full
for cash immediately prior to such change. The Exercise Price hereunder shall be
adjusted if and to the extent  necessary to reflect such change.  If the Warrant
Stock or other  securities  issuable  upon  exercise  hereof are  subdivided  or
combined into a greater or smaller number of shares of such security, the number
of shares issuable hereunder shall be proportionately increased or decreased, as
the case may be, and the  Exercise  Price  shall be  proportionately  reduced or
increased,  as the case may be, in both cases  according  to the ratio which the
total number of shares of such security to be outstanding immediately after such
even  bears  to  the  total  number  of  shares  of  such  security  outstanding
immediately  prior to such event.  The Corporation  shall give the holder prompt
written notice of any change in the type of securities issuable  hereunder,  any
adjustment of the Exercise Price for the securities issuable hereunder,  and any
increase or decrease in the number of shares issuable hereunder.

12.      Transferability; Compliance with Securities Laws

(a)  This Warrant may not be transferred or assigned in whole or in part without
     compliance  with all applicable  federal and state  securities  laws by the
     transferor   and   transferee   (including   the  delivery  of   investment
     representation  letters and legal opinions  reasonably  satisfactory to the
     Corporation,  if requested by the Corporation).  Subject such restrictions,
     prior to the  Expiration  Time,  this Warrant and all rights  hereunder are
     transferable  by the holder  hereof,  in whole or in part, at the office or
     agency  of the  Corporation  referred  to in  Section  1  hereof.  Any such
     transfer  shall  be made  in  person  or by the  holder's  duly  authorized
     attorney,  upon surrender of this Warrant together with the Assignment Form
     attached hereto properly endorsed.

(b)  The Holder of this Warrant,  by acceptance  hereof,  acknowledges that this
     Warrant and the  Warrant  Stock  issuable  upon  exercise  hereof are being
     acquired  solely for the  holder's own account and not as a nominee for any
     other party, and for investment,  and that the holder will not offer,  sell
     or otherwise  dispose of this Warrant or any shares of Warrant  Stock to be
     issued upon exercise hereof except under circumstances that will not result
     in a violation  of the  Securities  Act of 1933,  as amended,  or any state
     securities  laws.  Upon  exercise of this  Warrant,  the holder  shall,  if
     requested by the Corporation, confirm in writing, in a form satisfactory to
     the  Corporation,  that the shares of Warrant  Stock so purchased are being
     acquired solely for holder's own account and not as a nominee for any other

     "accredited investor" as defined in Rule 501(a) under the Securities Act of
     1933, as amended. Each certificate  representing the Warrant Stock or other
     securities  issued in respect of the  Warrant  Stock upon any stock  split,
     stock dividend,  recapitalization,  merger, consolidation or similar event,
     shall be stamped or otherwise imprinted with a legend  substantially in the

SECURITIES  LAWS OR COMPLIANCE  WITH AN  APPLICABLE  EXEMPTION  THEREFROM,  SUCH
COMPLIANCE,  AT THE OPTION OF THE CORPORATION,  TO BE EVIDENCED BY AN OPINION OF
SHAREHOLDER'S COUNSEL, IN FORM ACCEPTABLE TO THE CORPORATION,  THAT NO VIOLATION
OF SUCH  REGISTRATION  PROVISIONS  WOULD  RESULT FROM ANY  PROPOSED  TRANSFER OR
ASSIGNMENT.

which would have been received upon such reorganization,  consolidation, merger,
sale or  conveyance  by a holder of a number of shares of common  stock equal to

Stock or other  securities  issuable  upon  exercise  hereof are  subdivided  or
combined into a greater or smaller number of shares of such security, the number
of shares issuable hereunder shall be proportionately increased or decreased, as
the case may be, and the  Exercise  Price  shall be  proportionately  reduced or
increased,  as the case may be, in both cases  according  to the ratio which the
total number of shares of such security to be outstanding immediately after such
even  bears  to  the  total  number  of  shares  of  such  security  outstanding

                                  WARRANT M001

THIS WARRANT AND THE  SECURITIES  ISSUABLE  UPON  EXERCISE  HEREOF HAVE NOT BEEN
REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED, OR ANY APPLICABLE STATE
LAWS,  AND NO INTEREST  THEREIN  MAY BE SOLD,  DISTRIBUTED,  ASSIGNED,  OFFERED,

STATEMENT UNDER SUCH ACT AND APPLICABLE  STATE SECURITIES LAWS COVERING ANY SUCH
TRANSACTION OR SUCH TRANSACTION IS EXEMPT FROM THE REGISTRATION  REQUIREMENTS OF
SUCH ACT AND LAWS,  SUCH  COMPLIANCE,  AT THE OPTION OF THE  CORPORATION,  TO BE
EVIDENCED BY AN OPINION OF  WARRANTHOLDER'S  COUNSEL,  IN FORM ACCEPTABLE TO THE
CORPORATION, THAT NO VIOLATION OF SUCH REGISTRATION PROVISIONS WOULD RESULT FROM
ANY PROPOSED TRANSFER OR ASSIGNMENT.

                    SERIES "M" COMMON STOCK PURCHASE WARRANT

                       Bioject Medical Technologies Inc.

THIS  CERTIFIES  that for  good  and  valuable  consideration  received,  Robert
Gonnelli, a(n) individual or registered assigns, is entitled, upon the terms and
subject to the conditions hereinafter set forth, to acquire from Bioject Medical
Technologies Inc., an Oregon corporation (the  "Corporation") up to 80,243 fully
paid and  nonassessable  shares of  common  stock,  without  par  value,  of the
Corporation  ("Warrant  Stock")  at a purchase  price per share  (the  "Exercise
Price") of $1.10.

1.       Term of Warrant

Subject to the terms and  conditions  set forth  herein,  this Warrant  shall be
exercisable,  in whole or from  time to time  part,  at any time on or after the
date hereof and at or prior to 11:59 p.m.,  Pacific  Standard Time, on March 30,
2003 (the "Expiration Time").

2.       Exercise of Warrant

The  purchase  rights  represented  by  this  Warrant  are  exercisable  by  the
registered holder hereof, in whole or in part, at any time and from time to time
at or prior to the  Expiration  Time by the  surrender  of this  Warrant and the
Notice of  Exercise  form  attached  hereto  duly  executed to the office of the
Corporation at 7620 S.W. Bridgeport Road, Portland,  Oregon 97224 (or such other
office or agency of the  Corporation as it may designate by notice in writing to
the  registered  holder  hereof at the address of such holder  appearing  on the
books of the Corporation), and upon payment of the Exercise Price for the shares
thereby purchased (by cash or by check or bank draft payable to the order of the
Corporation or by  cancellation of indebtedness of the Corporation to the holder
hereof, if any, at the time of exercise in an amount equal to the purchase price
of the shares thereby purchased);  whereupon the holder of this Warrant shall be
entitled to receive  from the  Corporation  a stock  certificate  in proper form
representing the number of shares of Warrant Stock so purchased.

3.       Issuance of Shares; No Fractional Shares of Scrip

Certificates  for shares  purchased  hereunder  shall be delivered to the holder
hereof by the Corporation's transfer agent at the Corporation's expense within a
reasonable  time after the date on which this Warrant shall have been  exercised
in accordance with the terms hereof.  Each  certificate so delivered shall be in
such  denominations  as may be  requested  by the  holder  hereof  and  shall be
registered in the name of such holder or, subject to applicable laws, other name
as shall be requested by such holder.  If, upon exercise of this Warrant,  fewer
than all of the shares of Warrant Stock  evidenced by this Warrant are purchased
prior to the Expiration Time, one or more new warrants substantially in the form
of, and on the terms in, this Warrant will be issued for the remaining number of
shares of  Warrant  Stock not  purchased  upon  exercise  of this  Warrant.  The
Corporation  hereby  represents  and warrants  that all shares of Warrant  Stock
which may be issued upon the exercise of this Warrant will,  upon such exercise,
be duly and validly authorized and issued, fully paid and nonassessable and free
from all taxes, liens and charges in respect of the issuance thereof (other than
liens or charges  created by or imposed  upon the holder of the Warrant  Stock).

<PAGE>

The  Corporation  agrees that the shares so issued  shall be and be deemed to be
issued to such  holder  as the  record  owner of such  shares as of the close of
business  on the date on which  this  Warrant  shall have been  surrendered  for
exercise in  accordance  with the terms hereof.  No  fractional  shares or scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant. With respect to any fraction of a share called for upon the exercise of
this Warrant,  an amount equal to such  fraction  multiplied by the then current
price at which each share may be  purchased  hereunder  shall be paid in cash to
the holder of this Warrant.

4.       Charges, Taxes and Expenses

Issuance of  certificates  for shares of Warrant Stock upon the exercise of this
Warrant  shall be made  without  charge to the  holder  hereof  for any issue or
transfer  tax or other  incidental  expense in respect of the  issuance  of such
certificate,  all of which taxes and expenses shall be paid by the  Corporation,
and such certificates  shall be issued in the name of the holder of this Warrant
or in such  name or names as may be  directed  by the  holder  of this  Warrant;
provided,  however,  that in the event  certificates for shares of Warrant Stock
are to be issued in a name other  than the name of the  holder of this  Warrant,
this  Warrant  when  surrendered  for  exercise  shall  be  accompanied  by  the
Assignment Form attached hereto duly executed by the holder hereof.

5.       No Rights as Shareholders

This  Warrant does not entitle the holder  hereof to any voting  rights or other
rights as a shareholder of the Corporation prior to the exercise hereof.

6.       Registration Rights

The  Warrant  Stock  purchasable  upon  exercise  of this  Warrant  has not been
registered  under the  Securities  Act of 1933 or any state securities law. The
Corporation  shall have no obligation to register such Warrant Stock for resale.
The foregoing  notwithstanding,  any obligation undertaken by the Corporation to
register the Warrant Stock shall be limited to the Corporation's use of its best
efforts to do so, and in no event shall the  Corporation  be required to file or
maintain the effectiveness of a registration statement on Form S-1.


7.       Exchange and Registry of Warrant

This Warrant is exchangeable, upon the surrender hereof by the registered holder
at the above-mentioned office or agency of the Corporation, for a new Warrant of
like tenor and dated as of such exchange.  The Corporation shall maintain at the
above-mentioned  office or agency a registry showing the name and address of the
registered holder of this Warrant. This Warrant may be surrendered for exchange,
transfer or exercise,  in accordance with its terms, at such office or agency of
the Corporation,  and the Corporation shall be entitled to rely in all respects,
prior to written notice to the contrary, upon such registry.

8.       Loss, Theft, Destruction or Mutilation of Warrant

Upon receipt by the Corporation of evidence reasonably satisfactory to it of the
loss,  theft,  destruction  or mutilation of this Warrant,  and in case of loss,
theft or destruction of indemnity or security reasonably satisfactory to it, and
upon  reimbursement  to the  Corporation of all reasonable  expenses  incidental
thereto, and upon surrender and cancellation of this Warrant, if mutilated,  the
Corporation  will make and  deliver a new  Warrant of like tenor and dated as of
such cancellation, in lieu of this Warrant.

9.       Saturdays, Sundays and Holidays

If the last or appointed  day for the taking of any action or the  expiration of
any right required or granted herein shall be a Saturday or a Sunday or shall be
a legal holiday, then such action may be taken or such right may be exercised on
the next succeeding day not a Saturday, Sunday or legal holiday.

<PAGE>

10.      Merger, Sale of Assets, Etc.

If at any time the Corporation proposes to merge or consolidate with or into any
other  corporation,  effect  any  reorganization,  or  sell  or  convey  all  or
substantially  all of its assets to any other  entity,  then,  as a condition of
such reorganization,  consolidation, merger, sale or conveyance, the Corporation
or its successor,  as the case may be, shall enter into a supplemental agreement
to make lawful and adequate provision whereby the holder shall have the right to
receive,  upon exercise of the Warrant, the kind and amount of equity securities
which would have been received upon such reorganization,  consolidation, merger,
sale or  conveyance  by a holder of a number of shares of common  stock equal to
the number of shares issuable upon exercise of the Warrant  immediately prior to
such reorganization,  consolidation, merger, sale or conveyance. If the property
to  be  received  upon  such  reorganization,  consolidation,  merger,  sale  or
conveyance is not equity  securities,  the Corporation  shall give the holder of
this Warrant  fifteen (15) business  days prior  written  notice of the proposed
effective date of such  transaction,  and if this Warrant has not been exercised
by or on the effective date of such transaction, it shall terminate.

11.      Subdivision, Combination, Reclassification, Conversion, Etc.

If  the   Corporation   at  any  time  shall,   by   subdivision,   combination,
reclassification  of securities or otherwise,  change the Warrant Stock into the
same or a different  number of securities of any class or classes,  this Warrant
shall  thereafter  entitle  the  holder  to  acquire  such  number  and  kind of
securities as would have been issuable in respect of the Warrant Stock (or other
securities  which  were  subject  to the  purchase  rights  under  this  Warrant
immediately prior to such subdivision,  combination,  reclassification  or other
change) as the result of such change if this Warrant had been  exercised in full
for cash immediately prior to such change. The Exercise Price hereunder shall be
adjusted if and to the extent  necessary to reflect such change.  If the Warrant
Stock or other  securities  issuable  upon  exercise  hereof are  subdivided  or
combined into a greater or smaller number of shares of such security, the number
of shares issuable hereunder shall be proportionately increased or decreased, as
the case may be, and the  Exercise  Price  shall be  proportionately  reduced or
increased,  as the case may be, in both cases  according  to the ratio which the
total number of shares of such security to be outstanding immediately after such
even  bears  to  the  total  number  of  shares  of  such  security  outstanding
immediately  prior to such event.  The Corporation  shall give the holder prompt
written notice of any change in the type of securities issuable  hereunder,  any
adjustment of the Exercise Price for the securities issuable hereunder,  and any
increase or decrease in the number of shares issuable hereunder.

12.      Transferability; Compliance with Securities Laws

(a)  This Warrant may not be transferred or assigned in whole or in part without
     compliance  with all applicable  federal and state  securities  laws by the
     transferor   and   transferee   (including   the  delivery  of   investment
     representation  letters and legal opinions  reasonably  satisfactory to the
     Corporation,  if requested by the Corporation).  Subject such restrictions,
     prior to the  Expiration  Time,  this Warrant and all rights  hereunder are
     transferable  by the holder  hereof,  in whole or in part, at the office or
     agency  of the  Corporation  referred  to in  Section  1  hereof.  Any such
     transfer  shall  be made  in  person  or by the  holder's  duly  authorized
     attorney,  upon surrender of this Warrant together with the Assignment Form
     attached hereto properly endorsed.

(b)  The Holder of this Warrant,  by acceptance  hereof,  acknowledges that this
     Warrant and the  Warrant  Stock  issuable  upon  exercise  hereof are being
     acquired  solely for the  holder's own account and not as a nominee for any
     other party, and for investment,  and that the holder will not offer,  sell
     or otherwise  dispose of this Warrant or any shares of Warrant  Stock to be
     issued upon exercise hereof except under circumstances that will not result
     in a violation  of the  Securities  Act of 1933,  as amended,  or any state
     securities  laws.  Upon  exercise of this  Warrant,  the holder  shall,  if
     requested by the Corporation, confirm in writing, in a form satisfactory to
     the  Corporation,  that the shares of Warrant  Stock so purchased are being
     acquired solely for holder's own account and not as a nominee for any other
     party, for investment, and not with a view toward distribution or resale.

<PAGE>

(c)  Except as contemplated in the Registration  Rights  Agreement,  the Warrant
     Stock has not been and will not be registered  under the  Securities Act of
     1933, as amended,  and this Warrant may not be exercised  except by (i) the
     original  purchaser  of  this  Warrant  from  the  Corporation  or  (ii) an
     "accredited investor" as defined in Rule 501(a) under the Securities Act of
     1933, as amended. Each certificate  representing the Warrant Stock or other
     securities  issued in respect of the  Warrant  Stock upon any stock  split,
     stock dividend,  recapitalization,  merger, consolidation or similar event,
     shall be stamped or otherwise imprinted with a legend  substantially in the
     following  form  (in  addition  to any  legend  required  under  applicable
     securities laws):

THE SECURITIES  REPRESENTED  HEREBY HAVE NOT BEEN REGISTERED UNDER UNITED STATES
FEDERAL  OR STATE  SECURITIES  LAWS AND MAY NOT BE  OFFERED  FOR  SALE,  SOLD OR
OTHERWISE TRANSFERRED OR ASSIGNED FOR VALUE, DIRECTLY OR INDIRECTLY, NOR MAY THE
SECURITIES BE TRANSFERRED ON THE BOOKS OF THE CORPORATION,  WITHOUT REGISTRATION
OF  SUCH  SECURITIES  UNDER  ALL  APPLICABLE  UNITED  STATES  FEDERAL  OR  STATE
SECURITIES  LAWS OR COMPLIANCE  WITH AN  APPLICABLE  EXEMPTION  THEREFROM,  SUCH
COMPLIANCE,  AT THE OPTION OF THE CORPORATION,  TO BE EVIDENCED BY AN OPINION OF
SHAREHOLDER'S COUNSEL, IN FORM ACCEPTABLE TO THE CORPORATION,  THAT NO VIOLATION
OF SUCH  REGISTRATION  PROVISIONS  WOULD  RESULT FROM ANY  PROPOSED  TRANSFER OR
ASSIGNMENT.

13.      Representations and Warranties

The Corporation hereby represents and warrants to the holder hereof that:

(a)  during the period this Warrant is outstanding, the Corporation will reserve
     from its authorized and unissued common stock a sufficient number of shares

     deliver this  Warrant,  to sell and issue the Warrant Stock  hereunder,  to
     issue the common stock  issuable  upon exercise of the Warrant Stock and to
     carry out and perform its obligations under the terms of this Warrant; and

(d)  all  corporate  action on the part of the  Corporation,  its  directors and
     shareholders  necessary  for the  authorization,  execution,  delivery  and
     performance of this Warrant by the Corporation,  the  authorization,  sale,
     issuance  and  delivery of the  Warrant  Stock,  the grant of  registration
     rights  as  provided  herein  and  the  performance  of  the  Corporation's
     obligations hereunder has been taken;

(e)  the Warrant  Stock,  when issued in compliance  with the provisions of this
     Warrant and the  Corporation's  Articles of  Incorporation  (as they may be
     amended from time to time (the "Articles")),  will be validly issued, fully
     paid and  nonassessable,  and free of all taxes, liens or encumbrances with
     respect to the issue  thereof,  and will be issued in  compliance  with all

     rights, rights of first refusal or similar rights.

                    SERIES "N" COMMON STOCK PURCHASE WARRANT

                       Bioject Medical Technologies Inc.

THIS CERTIFIES that for good and valuable consideration  received,  __________i,
a(n) ________ or registered assigns, is entitled,  upon the terms and subject to
the  conditions   hereinafter   set  forth,  to  acquire  from  Bioject  Medical

Corporation  ("Warrant  Stock")  at a purchase  price per share  (the  "Exercise
Price") of $1.348.

1.       Term of Warrant

Subject to the terms and  conditions  set forth  herein,  this Warrant  shall be
exercisable,  in whole or from  time to time  part,  at any time on or after the
date hereof and at or prior to 11:59 p.m.,  Pacific  Standard Time, on March 31,
2003 (the "Expiration Time").

2.       Exercise of Warrant

The  purchase  rights  represented  by  this  Warrant  are  exercisable  by  the
registered holder hereof, in whole or in part, at any time and from time to time
at or prior to the  Expiration  Time by the  surrender  of this  Warrant and the
Notice of  Exercise  form  attached  hereto  duly  executed to the office of the
Corporation at 7620 S.W. Bridgeport Road, Portland,  Oregon 97224 (or such other
office or agency of the  Corporation as it may designate by notice in writing to
the  registered  holder  hereof at the address of such holder  appearing  on the
books of the Corporation), and upon payment of the Exercise Price for the shares
thereby purchased (by cash or by check or bank draft payable to the order of the
Corporation or by  cancellation of indebtedness of the Corporation to the holder
hereof, if any, at the time of exercise in an amount equal to the purchase price
of the shares thereby purchased);  whereupon the holder of this Warrant shall be
entitled to receive  from the  Corporation  a stock  certificate  in proper form
representing the number of shares of Warrant Stock so purchased.

3.       Issuance of Shares; No Fractional Shares of Scrip

Certificates  for shares  purchased  hereunder  shall be delivered to the holder
hereof by the Corporation's transfer agent at the Corporation's expense within a
reasonable  time after the date on which this Warrant shall have been  exercised
in accordance with the terms hereof.  Each  certificate so delivered shall be in
such  denominations  as may be  requested  by the  holder  hereof  and  shall be
registered in the name of such holder or, subject to applicable laws, other name
as shall be requested by such holder.  If, upon exercise of this Warrant,  fewer
than all of the shares of Warrant Stock  evidenced by this Warrant are purchased
prior to the Expiration Time, one or more new warrants substantially in the form
of, and on the terms in, this Warrant will be issued for the remaining number of
shares of  Warrant  Stock not  purchased  upon  exercise  of this  Warrant.  The
Corporation  hereby  represents  and warrants  that all shares of Warrant  Stock
which may be issued upon the exercise of this Warrant will,  upon such exercise,
be duly and validly authorized and issued, fully paid and nonassessable and free
from all taxes, liens and charges in respect of the issuance thereof (other than
liens or charges  created by or imposed  upon the holder of the Warrant  Stock).

<PAGE>

The  Corporation  agrees that the shares so issued  shall be and be deemed to be
issued to such  holder  as the  record  owner of such  shares as of the close of
business  on the date on which  this  Warrant  shall have been  surrendered  for
exercise in  accordance  with the terms hereof.  No  fractional  shares or scrip
representing  fractional  shares  shall  be  issued  upon the  exercise  of this
Warrant. With respect to any fraction of a share called for upon the exercise of
this Warrant,  an amount equal to such  fraction  multiplied by the then current
price at which each share may be  purchased  hereunder  shall be paid in cash to
the holder of this Warrant.

4.       Charges, Taxes and Expenses

Issuance of  certificates  for shares of Warrant Stock upon the exercise of this
Warrant  shall be made  without  charge to the  holder  hereof  for any issue or
transfer  tax or other  incidental  expense in respect of the  issuance  of such
certificate,  all of which taxes and expenses shall be paid by the  Corporation,
and such certificates  shall be issued in the name of the holder of this Warrant
or in such  name or names as may be  directed  by the  holder  of this  Warrant;
provided,  however,  that in the event  certificates for shares of Warrant Stock
are to be issued in a name other  than the name of the  holder of this  Warrant,
this  Warrant  when  surrendered  for  exercise  shall  be  accompanied  by  the
Assignment Form attached hereto duly executed by the holder hereof.

5.       No Rights as Shareholders

This  Warrant does not entitle the holder  hereof to any voting  rights or other
rights as a shareholder of the Corporation prior to the exercise hereof.

6.       Registration Rights

The  Warrant  Stock  purchasable  upon  exercise  of this  Warrant  has not been
registered under the Securities Act of 1933, as amended, or any state securities
law. The  Corporation  is not  obligated  to and does not plan to register  such
Warrant  Stock  for  resale.  The  foregoing  notwithstanding,   any  obligation
undertaken by the  Corporation to register the Warrant Stock shall be limited to
the  Corporation's  use of its best  efforts to do so, and in no event shall the
Corporation be required to file or maintain the  effectiveness of a registration
statement on Form S-1.


7.       Exchange and Registry of Warrant

This Warrant is exchangeable, upon the surrender hereof by the registered holder
at the above-mentioned office or agency of the Corporation, for a new Warrant of
like tenor and dated as of such exchange.  The Corporation shall maintain at the
above-mentioned  office or agency a registry showing the name and address of the
registered holder of this Warrant. This Warrant may be surrendered for exchange,
transfer or exercise,  in accordance with its terms, at such office or agency of
the Corporation,  and the Corporation shall be entitled to rely in all respects,
prior to written notice to the contrary, upon such registry.

8.       Loss, Theft, Destruction or Mutilation of Warrant

Upon receipt by the Corporation of evidence reasonably satisfactory to it of the
loss,  theft,  destruction  or mutilation of this Warrant,  and in case of loss,
theft or destruction of indemnity or security reasonably satisfactory to it, and
upon  reimbursement  to the  Corporation of all reasonable  expenses  incidental
thereto, and upon surrender and cancellation of this Warrant, if mutilated,  the
Corporation  will make and  deliver a new  Warrant of like tenor and dated as of
such cancellation, in lieu of this Warrant.

9.       Saturdays, Sundays and Holidays

If the last or appointed  day for the taking of any action or the  expiration of
any right required or granted herein shall be a Saturday or a Sunday or shall be
a legal holiday, then such action may be taken or such right may be exercised on
the next succeeding day not a Saturday, Sunday or legal holiday.

<PAGE>

10.      Merger, Sale of Assets, Etc.

If at any time the Corporation proposes to merge or consolidate with or into any
other  corporation,  effect  any  reorganization,  or  sell  or  convey  all  or
substantially  all of its assets to any other  entity,  then,  as a condition of
such reorganization,  consolidation, merger, sale or conveyance, the Corporation
or its successor,  as the case may be, shall enter into a supplemental agreement
to make lawful and adequate provision whereby the holder shall have the right to
receive,  upon exercise of the Warrant, the kind and amount of equity securities
which would have been received upon such reorganization,  consolidation, merger,
sale or  conveyance  by a holder of a number of shares of common  stock equal to
the number of shares issuable upon exercise of the Warrant  immediately prior to
such reorganization,  consolidation, merger, sale or conveyance. If the property
to  be  received  upon  such  reorganization,  consolidation,  merger,  sale  or
conveyance is not equity  securities,  the Corporation  shall give the holder of
this Warrant  fifteen (15) business  days prior  written  notice of the proposed
effective date of such  transaction,  and if this Warrant has not been exercised
by or on the effective date of such transaction, it shall terminate.

11.      Subdivision, Combination, Reclassification, Conversion, Etc.

If  the   Corporation   at  any  time  shall,   by   subdivision,   combination,
reclassification  of securities or otherwise,  change the Warrant Stock into the
same or a different  number of securities of any class or classes,  this Warrant
shall  thereafter  entitle  the  holder  to  acquire  such  number  and  kind of
securities as would have been issuable in respect of the Warrant Stock (or other
securities  which  were  subject  to the  purchase  rights  under  this  Warrant
immediately prior to such subdivision,  combination,  reclassification  or other
change) as the result of such change if this Warrant had been  exercised in full
for cash immediately prior to such change. The Exercise Price hereunder shall be
adjusted if and to the extent  necessary to reflect such change.  If the Warrant
Stock or other  securities  issuable  upon  exercise  hereof are  subdivided  or
combined into a greater or smaller number of shares of such security, the number
of shares issuable hereunder shall be proportionately increased or decreased, as
the case may be, and the  Exercise  Price  shall be  proportionately  reduced or
increased,  as the case may be, in both cases  according  to the ratio which the
total number of shares of such security to be outstanding immediately after such
even  bears  to  the  total  number  of  shares  of  such  security  outstanding
immediately  prior to such event.  The Corporation  shall give the holder prompt
written notice of any change in the type of securities issuable  hereunder,  any
adjustment of the Exercise Price for the securities issuable hereunder,  and any
increase or decrease in the number of shares issuable hereunder.

12.      Transferability; Compliance with Securities Laws

(a)  This Warrant may not be transferred or assigned in whole or in part without
     compliance  with all applicable  federal and state  securities  laws by the
     transferor   and   transferee   (including   the  delivery  of   investment
     representation  letters and legal opinions  reasonably  satisfactory to the
     Corporation,  if requested by the Corporation).  Subject such restrictions,
     prior to the  Expiration  Time,  this Warrant and all rights  hereunder are
     transferable  by the holder  hereof,  in whole or in part, at the office or
     agency  of the  Corporation  referred  to in  Section  1  hereof.  Any such
     transfer  shall  be made  in  person  or by the  holder's  duly  authorized
     attorney,  upon surrender of this Warrant together with the Assignment Form
     attached hereto properly endorsed.

(b)  The Holder of this Warrant,  by acceptance  hereof,  acknowledges that this
     Warrant and the  Warrant  Stock  issuable  upon  exercise  hereof are being
     acquired  solely for the  holder's own account and not as a nominee for any
     other party, and for investment,  and that the holder will not offer,  sell
     or otherwise  dispose of this Warrant or any shares of Warrant  Stock to be
     issued upon exercise hereof except under circumstances that will not result
     in a violation  of the  Securities  Act of 1933,  as amended,  or any state
     securities  laws.  Upon  exercise of this  Warrant,  the holder  shall,  if
     requested by the Corporation, confirm in writing, in a form satisfactory to
     the  Corporation,  that the shares of Warrant  Stock so purchased are being
     acquired solely for holder's own account and not as a nominee for any other
     party, for investment, and not with a view toward distribution or resale.

<PAGE>

(c)  Except as contemplated in the Registration  Rights  Agreement,  the Warrant
     Stock has not been and will not be registered  under the  Securities Act of
     1933, as amended,  and this Warrant may not be exercised  except by (i) the
     original  purchaser  of  this  Warrant  from  the  Corporation  or  (ii) an
     "accredited investor" as defined in Rule 501(a) under the Securities Act of
     1933, as amended. Each certificate  representing the Warrant Stock or other
     securities  issued in respect of the  Warrant  Stock upon any stock  split,
     stock dividend,  recapitalization,  merger, consolidation or similar event,
     shall be stamped or otherwise imprinted with a legend  substantially in the
     following  form  (in  addition  to any  legend  required  under  applicable
     securities laws):

THE SECURITIES  REPRESENTED  HEREBY HAVE NOT BEEN REGISTERED UNDER UNITED STATES
FEDERAL  OR STATE  SECURITIES  LAWS AND MAY NOT BE  OFFERED  FOR  SALE,  SOLD OR
OTHERWISE TRANSFERRED OR ASSIGNED FOR VALUE, DIRECTLY OR INDIRECTLY, NOR MAY THE
SECURITIES BE TRANSFERRED ON THE BOOKS OF THE CORPORATION,  WITHOUT REGISTRATION
OF  SUCH  SECURITIES  UNDER  ALL  APPLICABLE  UNITED  STATES  FEDERAL  OR  STATE
SECURITIES  LAWS OR COMPLIANCE  WITH AN  APPLICABLE  EXEMPTION  THEREFROM,  SUCH
COMPLIANCE,  AT THE OPTION OF THE CORPORATION,  TO BE EVIDENCED BY AN OPINION OF
SHAREHOLDER'S COUNSEL, IN FORM ACCEPTABLE TO THE CORPORATION,  THAT NO VIOLATION
OF SUCH  REGISTRATION  PROVISIONS  WOULD  RESULT FROM ANY  PROPOSED  TRANSFER OR
ASSIGNMENT.

13.      Representations and Warranties

The Corporation hereby represents and warrants to the holder hereof that:

(a)  during the period this Warrant is outstanding, the Corporation will reserve
     from its authorized and unissued common stock a sufficient number of shares

                            ASSET PURCHASE AGREEMENT

This  Agreement  is  dated  March  23,  1998,  by  and  among  BIOJECT   MEDICAL
TECHNOLOGIES INC., an Oregon corporation  ("Purchaser"),  VITAJET CORPORATION, a
California  corporation  ("Seller"),  and  SERGIO  LANDAU  and  MARA  L.  LANDAU
(collectively, "Landau").

                                R E C I T A L S:

Seller manufactures and sells a needle-free injection system under the trademark
"Vitajet" (the "Business").  Landau owns all of the issued and outstanding stock
of Seller. Seller wishes to sell substantially all of the assets of the Business
to Purchaser,  and Purchaser wishes to purchase such assets,  in accordance with
the terms of this Agreement.

NOW, THEREFORE, the parties agree as follows:

1.  Sale and Purchase.

Subject to the terms and conditions of this Agreement, Seller agrees to sell and
transfer to  Purchaser  on the Closing  Date (as  defined  below) and  Purchaser
agrees to buy from  Seller,  substantially  all of the  assets of the  Business,
which shall  include the  inventory  specified in Section 2, molds,  trademarks,
tradenames,  patents,  copyrights,  trade  secrets,  FDA  approval to market the
Vitajet injector,  customer lists, pending contracts to which Seller is a party,
and records of the Business,  together with the name  "Vitajet" and all goodwill
associated with such name (the "Assets"). A list of the Assets as of the date of
this  Agreement  is attached  hereto as Exhibit A. Items listed in Exhibit D and
Exhibit E attached hereto are also Assets being transferred.

2. Assets and Business Not to be Transferred.

Seller shall  retain,  and  Purchaser  shall not acquire,  Seller's  cash,  cash
equivalents, bank accounts, corporate franchise, prepaid expenses,  receivables,
furniture,  computers,  office materials and vehicles. In addition, Seller shall
retain all inventory of finished  Vitajet injector units and syringes except for
12  injector  units and 50 boxes of  syringes,  which  shall be  included in the
Assets.

3.  Liabilities.

Purchaser  does not assume any actual or  contingent  liability,  obligation  or
commitment of Seller,  other than  liabilities  and  obligations  related to the
contracts  that  Purchaser is assuming  that arise after  Closing.  Seller shall
satisfy all liabilities being retained by Seller out of the proceeds of the sale
or from other assets of Seller.

4.  Consideration.

The consideration (the "Purchase Price") for the transfer of the Assets shall be
as follows.

(a)  Purchaser  shall  issue to Seller at  Closing  (as  defined  in  Section 9)
     100,000 shares of Purchaser's common stock.

(b)  Purchaser  shall issue to Seller  payments of 60,000 shares of  Purchaser's
     common stock on each of March 31, 1999, 2000 and 2001, provided that Seller
     or  Seller's  agent,  Landau,  is making  reasonable  progress  toward  the
     achievement  of the following  goals (which are not  necessarily  listed in
     order of importance or priority):

(i)  Technology  transfer of current Vitajet 3 to Purchaser's  Portland facility
     to be completed by September 30, 1998.

(ii) Designing,  prototyping and validation testing of a modified version of the
     Vitajet 3, and an adaptation of Purchaser's standard disposable syringe, so
     that both products can work together,  for  subcutaneous  injections of 0.5
     cc. or less.

<PAGE>

(iii)Designing,  prototyping  and  validation  testing  of a low cost and  small
     (marker size) needle-free injector with disposable syringe for subcutaneous
     injections of 0.5 cc. or less.

(iv) Designing,  prototyping  and  validation  testing of a  syringe/spacer  and
     necessary  adaptation of the standard Biojector or alternate injector,  for
     intradermal injections of 0.5 cc. or less.

The goals specified above, which currently are expected to be completed by March
31, 2001, except as specified above, are subject to reasonable  modifications by
Purchaser.

(c)  Purchaser  shall  issue to  Seller  up to an  additional  90,000  shares of
     Purchaser's  common stock if certain  conditions are met by March 31, 2001.
     Seller  will be entitled  to receive  such shares in the amounts  specified
     below if Seller's  existing  products or new products designed by Seller or
     Seller's  agent,  Landau (such  existing and new products to be referred to
     herein as the "Products"), result in aggregate revenues to Purchaser in the
     amounts specified below:

Aggregate Revenues                    Number of Shares

Up to $1,000,000                      30,000
$1,000,001 to $2,000,000              Additional 30,000
More than $2,000,000                  Additional 30,000

Aggregate  revenues  to be  received  by  Purchaser  from the  Products  will be
calculated as follows:

(i)  If one or more partnership  agreements  relating to the Products are signed
     by Purchaser and a third party by March 31, 2001, the revenues to be earned
     by Purchaser under each such  partnership  agreement will equal the amounts
     committed to be paid to Purchaser  under such  partnership  agreement  with
     respect to the  Products  during the first ten years after the  partnership
     agreement is signed; and

(ii) If the  Products are sold outside of a  partnership  arrangement,  revenues
     from such sales will be included in the calculation as Products are shipped
     to third-party purchasers of the Products; provided, however, that Products
     must be shipped by March 31,  2001 to be  included  in the  calculation  of
     aggregate revenues.

All revenues  committed to be received under each  partnership  agreement during
the first ten years after the  agreement is signed and all sales of the Products
outside of partnership arrangements will be aggregated in meeting the milestones
specified above.  Once Seller has met a milestone,  Purchaser will issue a stock
certificate representing the earned shares within 30 days thereafter.

(d)  The stock  certificates  representing the shares issued hereunder will bear
     such  legends  as  the  Company  shall  deem  appropriate  to  reflect  the
     restrictions on transfer imposed by federal and applicable state securities
     laws.  Purchaser  agrees  to use  reasonable  efforts  to file Form S-3 (or
     successor  form) to register  the shares  issued  hereunder  within 90 days
     after each such issuance of shares.

(e)  With respect to each Vitajet  injector  unit  purchased in excess of the 12
     units  specified in Section 2, Purchaser shall pay to Seller $110. For each
     box of three-month  supply of disposable items for inventory that Purchaser
     purchases  in excess of the 50 boxes of  syringes  specified  in Section 2,
     Purchaser shall pay Seller $19.

<PAGE>

5.  Purchase Price Allocation.

                    vesting  date  and an  expiration  date of April  30,  2000.
                    However,  in the event that Employee  fails to so cooperate,

                    per share of all of the  foregoing  options  will  remain as
                    stated on Attachment B.

                    In  consideration  for this  Agreement,  Employee  agrees to
                    waive and  forfeit  any right to the June 11,  1997,  25,000

                    options.  All other  obligations  of the Employee  under the
                    Stock Option Agreement shall remain enforceable.

                    Employee  acknowledges  and agrees that after executing this
                    Agreement, she will have no Bioject stock options other than
                    the 130,000 vested options with an expiration  date of April
                    30, 2000 and the 25,000 unvested  options which will vest at

                    30, 2000, as described  above.  The parties  acknowledge and
                    agree  that  Employee's   remaining  25,000  unvested  stock
                    options (granted June 11, 1997) are deemed terminated, as of
                    the  effective  date of  this  Agreement.  Employee  further
                    acknowledges  and  agrees  that she is not  entitled  to any
                    options in the future  beyond the exchanged  options  stated
                    herein.

             Bioject  acknowledges that it has obtained all necessary  approvals
and authorizations from Bioject's Boards of Directors and appropriate committees
for the consideration granted Employee in paragraph 2 herein.

             3. Employee  acknowledges  and warrants that by April 30, 1998, she
will have  submitted  any and all  vouchers,  bills and receipts  verifying  all
out-of-pocket  business  expenses  necessarily  incurred by Employee  during her
employment with Bioject. Bioject agrees to reimburse Employee in a timely manner
for all such  out-of-pocket  business  expenses  in  accordance  with  Bioject's
reimbursement policies.

             4. The parties  acknowledge that BMT is a reporting  company within

             5. Employee  accepts  Bioject's  undertakings  in this Agreement as
full  settlement  of any and all claims,  known or  unknown,  arising out of, or
related to, Employee's  employment with Bioject, or its termination,  including,
but not limited to, any claims of  discrimination  or wrongful  discharge.  This
includes,  but is not  limited  to,  claims  under  the  Age  Discrimination  in
Employment  Act of 1967 ("ADEA"),  29 U.S.C.  ss. 621 et seq, the Americans with
Disabilities  Act of 1990 ("ADA"),  42 U.S.C. ss. 12101 et seq, Title VII of the
Civil Rights Act of 1964,  42 U.S.C.  ss. 1981,  and Chapters 652 and 659 of the
Oregon Revised Statutes.  These claims are examples, not a complete list, of the
released claims,  as it is the parties' intent that Employee release any and all
claims, of whatever kind or nature,  in exchange for the severance  arrangements
set forth in paragraph 2 above.  Employee  realizes this  constitutes a full and
final settlement of any and all such claims, and except for obligations  arising
under this Agreement, this settlement releases Bioject and any related companies
(and their owners, officers, directors,  employees, and anyone else against whom
Employee could assert a claim based on her  employment or  termination  thereof)
from any further  liability to Employee (or to anyone else Employee has power to
bind in this settlement) in connection with such claims.

             In exchange  for  Employee's  agreements  and  obligations  herein,
Bioject,  on behalf of  themselves  and their  officers  and  directors,  hereby
releases,  acquits,  and forever  discharges  Employee and her past, current and
future agents, assigns,  attorneys,  representatives and affiliates from any and
all claims,  demands,  damages,  costs, attorney fees,  liabilities,  claims for
contribution,  and claims for indemnity, of every kind and nature, whether known
or  unknown,  fixed or  contingent,  including  but not  limited to, any and all
claims  arising  out of, or in any way related to,  Employee's  employment  with
Bioject through April 30, 1998.

             6. Tender and delivery of the wages,  severance pay and benefits as
described in paragraphs 1-2 herein shall constitute full satisfaction by Bioject
of any and all claims by Employee for wages, vacation pay (FTO),  severance pay,
and any other compensation,  benefits or leave of any kind to which Employee may
be entitled.

             7. Employee  acknowledges  that her obligations  under the parties'
Executive  Employment  Contract  dated  January 18, 1993  (hereafter  "Executive
Employment  Contract"  and  attached  hereto  as  Attachment  A) shall  continue
following  her  separation  from  employment  with  Bioject.  These  obligations
specifically  include,  but are not  limited  to,  the  restrictions  imposed on
Employee  regarding  competition  with Bioject and involvement  with conflicting
organizations,  products and services,  as fully set forth in section 6.1 of the
Executive  Employment  Contract,  and  Employee's  obligations  with  respect to
patents  and  copyrights,  as fully set forth in  section  6.2 of the  Executive
Employment  Contract.  These  obligations  are in  addition  to any  obligations
imposed under federal or state law.


<PAGE>


             8. Bioject  acknowledges  that its indemnity  obligations under the
parties'  Executive  Employment  Contract (section 6.6) shall survive Employee's
separation  from  employment  with  Bioject  and  continue  indefinitely.  These
obligations  are in  addition  to  obligations  imposed by state law,  Bioject's
by-laws, and Bioject's directors and officers' and other insurance policies.

             9.  Employee  agrees  to  keep  confidential  all  confidential  or
proprietary  information  disclosed directly or indirectly by Bioject and agrees
that she will not,  directly or indirectly,  use,  disclose,  or divulge for any
purpose  such  confidential  or  proprietary  information  obtained  during  her
employment with Bioject or at any other time without the prior written  approval
of Bioject. Such confidential and proprietary  information includes,  but is not
limited to, the agenda,  decisions or other information  relating to meetings or
discussions  held by and  between  Bioject's  officers,  directors  or  board of
directors,  any and all employment  information  relating to any past or present
Bioject employees or prospective  employees including salaries,  severance,  and
disciplinary  actions,  Bioject's  product design and  development  information,
proprietary   production   processes,   research  and  development   strategies,
scientific and technological data, formulae or prototypes,  non-public financial
information,  business or marketing  strategies,  customer lists and information
regarding Bioject's past, present, prospective and future customers.

             10.  The  parties  agree to keep the terms and  conditions  of this
Agreement confidential and not disclosed to any individual or entity that is not
a party to this Agreement except as required by law or provided herein. Employee
may  disclose  the fact and  terms of this  Agreement  to her  immediate  family
members,  attorney,  tax advisor,  accountant  and financial  consultant  and to
Bioject's internal financial  management,  outside auditors and legal counsel as
may be  required to fulfill  Employee's  duties as Chief  Financial  Officer and
agrees to instruct  them to make no further  disclosures,  except as required by
law.  Bioject may disclose the fact and terms of this Agreement to its officers,
directors, internal financial management, outside auditors, legal counsel and as
required by law as a publicly traded company.

             11. The parties to this Agreement  expressly  agree to refrain from
making any disparaging, misleading or false remarks concerning each other or any
of the  entities or  individuals  released in paragraph 5 above and will conduct
themselves in a manner that does not damage or undermine the  reputation of each
other or any entity or person identified in paragraph 5 above.

             12. Employee  warrants that upon her departure,  she will return to
Bioject all company  property in her  possession,  including  documents  and all
materials of any nature  pertaining to her work with Bioject whether or not they
contain confidential or


<PAGE>


proprietary information.

             13.  Employee  expressly  waives  and will not  assert any claim of
right to reinstatement of employment with Bioject or its related entities.

             14.  The  parties  acknowledge  and agree  that any  breach of this
Agreement by either party shall  subject that party to liability  for the actual
and  consequential  damages resulting from the breach.  The non-breaching  party
shall also be  entitled  to all  available  equitable  relief as a result of the
breach,  including  imposition of an injunction.  This provision  applies to any
breach of this Agreement.

             15. The parties  agree that this  Agreement  shall be construed and
interpreted  according to the laws of the State of Oregon  (excluding  choice of
law provisions).  The parties agree that the forum for resolution of any dispute
arising out of or relating  to: (1)  Employee's  employment  with  Bioject;  (2)
Employee's  termination  of employment  with Bioject;  or (3) any breach of this
Agreement will be by final and binding arbitration in Multnomah County,  Oregon,
utilizing  the  mediation  services of  Arbitration  Service of  Portland,  Inc.
("ASP") or other mutually agreed upon arbitration  service. The arbitrator shall
have the same  authority  to award  remedies  and damages as provided to a judge
and/or jury under  applicable  law. The arbitrator  shall apply Oregon State law
(excluding choice of law provisions) and applicable  federal law in deciding all
substantive aspects of the dispute, and all procedural issues not covered by the
ASP arbitration rules. The arbitrator shall not have the power to alter,  amend,
or modify  any  provision  of this  Agreement.  The  prevailing  party  shall be
entitled to recover reasonable  attorney fees and other costs of the arbitration
from  the  other  party.  Judgment  on  the  award  rendered  pursuant  to  such
arbitration may be entered in any court having jurisdiction thereof.

             16. The parties agree that this  Agreement  supersedes  any and all
other prior  agreements  or  understandings,  both oral and written,  except the
Employer's and Employee's  obligations under the Agreements  attached hereto and
referenced  herein.  The parties  further  agree that this  Agreement  cannot be
modified  without the express  written  consent and  agreement  of both  parties
hereto.

             17. The parties  agree that the  provisions  in this  Agreement are
separable  and  that  in the  event  any  provision  is  deemed  ineffective  or
unenforceable,   they  are  separable  from  the  remaining  provisions  of  the
Agreement, which provisions shall remain binding on the parties.

             18.  Employee  confirms that she has carefully read this Agreement.
Employee acknowledges that she has been advised to consult with an attorney, and
has in fact done so,  before  signing this  Agreement,  which  Employee has been
given


<PAGE>


twenty-one (21) days to consider, and which she may revoke within seven (7) days
after signing.  Employee  acknowledges that she has signed this Agreement of her
own free will and with the advice of counsel. This offer expires on the 22nd day
after it has been extended to Employee by Bioject.

                                      Rent


Section  4.01 - Basic  Rent.  Tenant  agrees to pay  Landlord  the Basic Rent as
annual rent for the  Premises for each Lease Year,  without  offset or deduction
and without  previous  demand.  Tenant agrees to pay Basic Rent in equal monthly
installments in advance on the first day of each calendar month during the Lease

                                    ARTICLE 6

                            Operating Expenses; Taxes


Section 6.01 - Operating Expenses and Taxes.  Tenant agrees to pay Landlord,  as

in this Article 6,  pro-rated for any partial  calendar year falling  within the
Lease  Term,  and (ii) all  Taxes  assessed  with  respect  to  Improvements  or
structures  anywhere in the Park constructed by or on behalf of Tenant after the
Substantial Completion Date.

Section 6.02 - Monthly  Payments of  Additional  Rent.  Tenant  agrees to pay to
Landlord in advance for each  calendar  month of the Lease Term,  as  Additional


<PAGE>


Rent,  Operating  Expenses  and  Taxes in an amount  equal to (a)  1/12th of the
product of (i) Estimated  Operating  Expenses for the then current calendar year
times (ii) the Rentable Area of the Premises,  plus (b) 1/12th of the product of
(i) Estimated  Taxes for the then current  calendar year times (ii) the Rentable
Area of the Premises. Tenant agrees to pay the amount payable under this Section
6.02 with  Tenant's  monthly  payments of Basic Rent.  The amounts  paid will be
credited by Landlord to Tenant's obligations under Section 6.01. For the balance
of the first calendar year at the beginning of the Lease Term the amount payable
by Tenant  each month with  respect to  Tenant's  Share of  Estimated  Operating
Expenses  and  Estimated  Taxes will be the Initial  Monthly  Payment  stated in
Section 1.01,  which amount will be pro-rated for the partial month,  if any, at
the  beginning  of the Lease Term and paid  beginning  on the Term  Commencement
Date.

Section 6.03 - Annual  Statements.  Within sixty (60) days after the end of each
calendar  year,  Landlord  agrees to render to Tenant a  statement,  prepared in
accordance with generally accepted accounting  practices,  showing in reasonable
detail  (i) for the  calendar  year just ended (if any) (a) the amount of Taxes,
(b) the amount of Operating  Expenses and (c) a calculation of Tenant's Share of
Taxes and Operating  Expenses,  and (ii) for the then current calendar year, the
amount of  Estimated  Operating  Expenses  and  Estimated  Taxes  determined  by
Landlord  in the  reasonable  exercise  of  its  judgment.  Estimated  Operating
Expenses  and  Estimated  Taxes for the  calendar  year in which the Lease  Term
begins  are the sums set forth in  Section  1.01.  If the total  amount  paid by
Tenant on account of Operating  Expenses or Taxes or both in any  calendar  year
exceeds the actual amount of Tenant's  Share of Operating  Expenses or Taxes for
the year,  then the excess  will be  credited  by  Landlord  against the monthly
installments  of Additional Rent next falling due or refunded to Tenant upon the
expiration or termination of this Lease,  if earlier  (unless such expiration or
termination  is the  result  of an Event of  Default).  If the  total  amount of
Operating  Expenses or Taxes or both paid by Tenant in any calendar year is less
than the actual amount of Tenant's Share of Operating  Expenses or Taxes for the
year,  then Tenant agrees to pay the  difference to Landlord  within thirty (30)
days after receipt by Tenant of Landlord's  statement.  Not more frequently than
once each Lease Year,  Tenant  may,  at its expense and after ten (10)  Business
Days prior notice, audit Landlord's records relating to Operating Expenses.

Section 6.04 - Assessments and Other Taxes. Landlord agrees that all special and
general  assessments  will be paid  in  installments  over  the  longest  period
permitted  by law and that the amount of Taxes  shown on each  annual  statement
will include  only the portion due in that year.  Nothing in this Lease shall be
construed to require Tenant to pay any inheritance,  estate, excise, succession,
transfer,  gift, franchise,  income, gross receipt, or profit taxes that are, or
may be, imposed upon Landlord,  its successors or assigns,  except to the extent
such taxes are in  substitution  for Taxes as now imposed on the  Building,  the
Land, the Premises or this Lease.

Section  6.05 -  Accounting  Periods.  Landlord may from time to time change the
periods  of  accounting  under  this  Lease to any  annual  period  other than a
calendar  year.  Upon any such change,  all items  referred to in this Article 6
will be  appropriately  apportioned.  In all  statements  rendered under Section
6.03,  amounts  for  periods  partially  within  and  partially  outside  of the
accounting  periods will be appropriately  apportioned.  Any items which are


<PAGE>


not  determinable  at the time of a  statement  will be included on the basis of
Landlord's  estimate.  Promptly  after  determination,  Landlord  will  render a
supplemental statement in which appropriate adjustment will be made.

Section  6.06 - Abatement  of Taxes.  Landlord  may at any time and from time to
time make application to the appropriate Governmental Authority for an abatement
of  Taxes.  Landlord  agrees  to make such an  application  at any time  tenants
occupying  more than 60% of the  Rentable  Area of the  Building  under  written
Occupancy  Arrangements  directly with the Landlord request that Landlord do so.
If (i) such an application is successful and (ii) Tenant has made any payment in
respect of Taxes under this  Article 6 for the period with  respect to which the
abatement  was  granted,  Landlord  agrees (a) to deduct  from the amount of the
abatement all expenses  incurred by it in connection  with the  application  (b)
within thirty (30) days after receipt of the abatement  amount, to pay to Tenant
Tenant's  Share  (adjusted  for any period  for which  Tenant had made a partial
payment) of the  abatement,  with  interest,  if any,  paid by the  Governmental
Authority on such abatement, and (c) retain the balance, if any.

Section 6.07 - Exemption From Taxes.  As provided in Section 6 of Chapter 317 of
the Acts of 1983,  Landlord may be or become  exempt from the  obligation to pay
Taxes if it leases any part of the Building to an organization exempt from taxes
under the United States Internal Revenue Code. If Tenant is able to establish to
Landlord's satisfaction the amount of the reduction in Taxes during any calendar
year which is a result of this Lease and Tenant's  tax-exempt  status,  Tenant's
obligation  to pay Taxes for such  calendar  year as provided in this  Article 6
will abate in the same  amount,  or the  amount,  if  previously  paid,  will be
refunded to Tenant. If Tenant is not tax-exempt but Landlord's obligation to pay
Taxes is abated because of the tax-exempt  status of any other tenant or tenants
of the Building,  Landlord  reserves the right to increase  Tenant's Share as it
relates  to Taxes so that the Taxes  payable  with  respect  to the Land and the
Building for any calendar year during the Lease Term are  equitably  apportioned
among the tenants of the Building who are not exempt from taxation.


                                    ARTICLE 7

                                  Improvements

Fit-up as described in the Working Drawings. Landlord agrees to perform all work

and Insurance Requirements, subject to the provisions of the Work Letter. Unless
otherwise  agreed,  Tenant  agrees to pay Tenant's  Cost as  Additional  Rent in
installments  as the work  progresses  as  provided  in the  agreement  with the
contractor  performing  the  work  and  in  any  event  on or  before  the  Term
Commencement Date.

Section 7.02 - Time for Completion. Landlord agrees to use due diligence to have
the  Premises  ready for  occupancy  on or  before  the Term  Commencement  Date
referred to in Section 1.01. Reference is made to the Work Letter for details of
the completion process.

days  before it occurs,  Landlord  agrees to give  Tenant a notice  stating  the
Substantial Completion Date.

Section 7.04 - Delays.  If Landlord is delayed in substantially completing
Tenant Fit-up as the result of

(a)  delay by Tenant or any Person employed by Tenant in delivery to Landlord of
     any plans, design work and detailed drawings, or

(b)  Tenant's  requests for special  work not part of the work  described in the
     Working  Drawings or for changes to the Working  Drawings after approval by
     Tenant (notwithstanding Landlord's approval of such changes), or

(c)  delays in  performance  by Tenant or any Person  employed  by Tenant  which
     cause delays in the  completion of any work to be done by Landlord or which
     otherwise delay the substantial completion of the Premises, or

(d)  any fault, negligence, omission, or failure to act on the part of Tenant or
     its  agents,  contractors,   workmen,  mechanics,  suppliers  or  invitees,


provided  Tenant has been given notice of each such delay,  the Premises will be
substantially  completed on (and the Term  Commencement  Date will be) that date
determined by Landlord, in the reasonable exercise of its judgment, on which the
Substantial  Completion  Date would have occurred but for the delays referred to
in this Section 7.04.

Section 7.05 - Tenant's Access to the Premises.  Tenant and Tenant's agents,  at
Tenant's  sole risk,  may, with  Landlord's  prior  consent,  enter the Premises
before  the  Term  Commencement  Date in  order to (a)  install  its  furniture,
furnishings  and equipment and (b) perform or inspect work necessary to make the
Premises ready for Tenant's use and occupancy.  If Landlord permits entry before
the Term  Commencement  Date,  the  permission  is  conditioned  upon (i) Tenant
delivering to Landlord  evidence of the insurance  required  under Section 15.01
and (ii) Tenant and Tenant's agents, contractors,  workmen, mechanics, suppliers
and  invitees,  working in harmony  with  Landlord and  contractors  working for
Landlord and with other tenants of the Building.  If at any time Tenant's  entry
causes or threatens to cause disharmony or interfere with the orderly completion
or operation of the Building,  Landlord may withdraw the permission  upon notice
to Tenant.  Any entry by Tenant will be deemed to be under all of the provisions
of this Lease except the covenant to pay Rent. Except for negligence of Landlord
and its  employees,  if Tenant or its agents enter the Premises  before the Term
Commencement  Date,  Landlord will not be liable for and Tenant agrees to assume
the entire risk for any loss or damage which may occur to any Improvements or to
any property placed in the Premises before the Term Commencement Date.

Section  7.06 -  Improvements  by  Tenant.  Tenant  agrees  not to hang  shades,
curtains,  signs, awnings or other materials in any window, attach any materials
to or make any change in the appearance of any glass visible from outside of the
Premises,  add any window treatment of any kind or make  Improvements or install
furniture visible from outside of the Premises, without Landlord's prior written
consent.  Tenant agrees not to make any 


<PAGE>


Improvements before or during the Lease Term, the total cost of which during any
twelve (12)  consecutive  months exceeds $5,000,  unless Landlord first approves
the plans and specifications for the Improvements and the contractors performing
the work.  Tenant  agrees  not to make any  Improvements  which  would (a) delay
completion of the Premises or the Building,  or (b) require  unusual  expense to
readapt the Premises to normal  research  and  development,  general  office and
limited light  manufacturing  use upon termination of this Lease or (c) increase
(i) the cost of  Landlord's  Work or insurance or (ii) Taxes.  All  Improvements
will become part of the Premises and property of Landlord upon their  completion
or  installation  except  to the  extent  Landlord  specifies  that they must be
removed  at  Tenant's  expense  on the  Lease  Termination  Date  as an  express
condition to Landlord's approval of their initial installation. The construction
of  Improvements  by  Tenant  and  the   installation  of  Tenant's   furniture,
furnishings  and equipment will be coordinated  with any work being performed by
Landlord and will be performed  in such manner as to maintain  harmonious  labor
relations  and not to damage the  Building  or the  Premises or  interfere  with
Building  operation.  Except for work done by or through  Landlord before making
any Improvements,  Tenant will: secure all necessary Authorizations;  deliver to
Landlord a statement of the names of all its contractors and  subcontractors and
the estimated cost of all labor and material to be furnished by them; cause each
contractor  to carry (1) worker's  compensation  insurance in statutory  amounts
covering all the contractor's and subcontractor's  employees,  (2) comprehensive
public liability  insurance with such limits as Landlord may reasonably require,
but in no event less than  $1,000,000,  and (3) property  damage  insurance with
limits of not less than $300,000 (all such  insurance to be written by companies
approved  by  Landlord  and  insuring   Landlord  and  Tenant  as  well  as  the
contractors), and to deliver to Landlord certificates of all such insurance; and
secure casualty  insurance  against loss or damage to the  Improvements  pending
completion and deliver evidence of such insurance to Landlord.  Tenant agrees to
pay  promptly  when due the  entire  cost of any work  done in the  Premises  by
Tenant, its agents,  employees, or independent contractors,  and not to cause or
permit any liens for labor or materials  performed  or  furnished in  connection
with its work to attach to the Premises and  immediately  to discharge  any such
liens  which may  attach.  All  construction  work done by Tenant,  its  agents,
employees  or  independent  contractors  will be done in a good and  workmanlike
manner and in compliance with all Legal Requirements and Insurance Requirements.
Landlord  may  inspect  the work at any time and will  promptly  give  notice to
Tenant of any observed defects.

to the  installation  in the  Premises,  at Tenant's  request,  of any unique or
special  materials,  finish or  equipment,  Tenant agrees to pay the Landlord an
amount equal to the increase in cost. All charges for  Additional  Services will
be payable within ten (10) days after the date on which they are billed.

in  damages  nor in  default  under  this  Lease  for any  failure  or  delay in
furnishing  Basic  Services or Additional  Services when the failure or delay is
caused by  Unavoidable  Delays.  No failure or delay by Landlord  in  furnishing
Basic  Services  or  Additional  Services  caused by  Unavoidable  Delays may be
claimed or pleaded as an eviction or disturbance of Tenant's  possession or give
Tenant any right to  terminate  this Lease or give rise to any claim for set-off

capacity is not exceeded and to avert possible  adverse effect upon the Building
electric  service,  Tenant agrees it will not,  without prior written  notice to
Landlord in each instance,  connect to the Building electric distribution system
any fixtures,  appliances  or equipment  which operate on a voltage in excess of

appliances or equipment,  all additional risers or other equipment  required for
the connection will be provided by Landlord, and the cost will be paid by Tenant
on Landlord's demand.

                Assignment and Subletting: Occupancy Arrangements


Section 13.01 - Assignment and  Subletting.  Tenant agrees not to enter into any
Occupancy  Arrangement,  either  voluntarily or by operation of law, (other than
with a Person who is affiliated  with Tenant and for a period ending when and if
such Person  ceases to be  affiliated  with  Tenant)  without the prior  written
consent  of  Landlord.  For  purposes  of this  Article  13,  a  Person  will be
considered to be affiliated with Tenant if such Person,  directly or indirectly,
controls, is controlled by or is under common control with Tenant.

Section  13.02 -  Procedure.  If  Tenant  intends  to  enter  into an  Occupancy
Arrangement which requires  Landlord's  consent,  Tenant agrees to give Landlord
notice of the name of (and a financial  statement  with respect to) the proposed
occupant,  the exact terms of the Arrangement  and a precise  description of the
portion of the  Premises  intended to be subject to the  Occupancy  Arrangement.
Within thirty (30) days after  receipt of the notice,  Landlord will (i) consent
to the  Occupancy  Arrangement,  or (ii)  refuse  to  consent  to the  occupancy
Arrangement,  or (iii) notify  Tenant of Landlord's  election to terminate  this
Lease with  respect to so much of the  Premises  as is intended to be subject to
the Occupancy  Arrangement.  If Landlord consents to the Occupancy  Arrangement,
Tenant agrees (i) to enter into the  Arrangement on the exact terms described to
Landlord  within  thirty  (30) days after  Landlord's  consent and to deliver to
Landlord  and to the holder of any first  mortgage  on the  Building an executed
original counterpart of the Occupancy  Arrangement and (ii) to remain liable for
the payment and  performance of the  provisions of this Lease.  If Tenant enters
into an Occupancy  Arrangement,  Tenant  agrees to pay to Landlord when received
the excess, if any, of amounts received in respect of the Occupancy  Arrangement
over the Rent.  Any Occupancy  Arrangement  will  expressly  incorporate  and be
subject to the terms of this  Lease,  which terms will be binding on all parties
to the Occupancy Arrangement.  If Landlord consents to and Tenant does not enter
into the  Arrangement  within the thirty (30) day period,  such  consent will be
deemed  revoked and Tenant will again comply with the terms of this Section.  If
Landlord  elects to  terminate  this Lease with  respect to that  portion of the
Premises to be subject to the Occupancy  Arrangement,  this Lease will terminate
as of the date  specified  in the  election,  which  date  will be not less than
thirty  (30) days nor more than sixty (60) days after the date of the  election;
provided that Tenant may, at any time before the date of  termination,  withdraw
its request for Landlord's consent to an Occupancy Arrangement.  Such withdrawal
by Tenant will nullify  Landlord's  election to  terminate,  and this Lease will
remain in effect as if no  election  by  Landlord  had been  made.  If  Landlord
terminates this Lease,  all Rent due will be adjusted as of the day the Premises
(or the portion affected by the  termination)  are redelivered to Landlord.  Any
portion  of the  Premises  redelivered  to  Landlord  will  be in the  condition
specified in Section 9.08.

                                    Indemnity


<PAGE>


Section  14.01 - Tenant's  Indemnity.  Except to the extent  waived by  Landlord
under the  provisions  of Section  16.02,  Tenant  agrees to indemnify  Landlord
against all claims,  losses and expenses,  including reasonable attorneys' fees,
which  may be  imposed  upon or  incurred  by  Landlord  by reason of any of the
following occurrences:

(a)  any act or  omission  on the  Premises  by Tenant or any Person  other than
     Landlord, its agents, contractors, licensees or invitees;

(b)  any use, non-use, possession, occupation, condition, operation, maintenance
     or management of the Premises;

(c)  any  act or  omission  on  the  part  of  Tenant,  or  any  of its  agents,
     contractors,  licensees  or  invitees,  whether  or  not  occurring  on the
     Premises;

(d)  any accident,  injury or damage to any Person or property  occurring in the
     Premises,  not  due to  any  act  or  omission  of  Landlord,  its  agents,
     contractors or licensees;

(e)  any  failure  on the part of Tenant to comply  with any of its  obligations
     under this  Lease,  whether or not such  failure  constitutes  a Default or
     Event of Default;

(f)  any  untrue  or   misleading   statement   of  a   material   fact  or  any
     misrepresentation  of a  material  fact  made by or on  behalf of Tenant in
     connection with the negotiation of this Lease; or

(g)  any release or threat of release of Hazardous  Substances by Tenant, or any
     of its agents, contractors, licensees or invitees, whether or not occurring
     on the Premises.

Section 14.02 - Claims by Landlord.  If a proceeding is brought against Landlord
arising  out of an  occurrence  described  in Section  14.01,  upon  notice from
Landlord  Tenant agrees,  at its expense,  to defend the proceeding  using legal
counsel reasonably satisfactory to Landlord or, if applicable, Tenant's insurer,
provided that Tenant has not been  prejudiced by failure or delay on the part of
Landlord to give Tenant prompt notice of the proceeding.  If Tenant has supplied
Landlord with insurance  covering an occurrence  described in Section 14.01,  no
claim may be made  against  Tenant with  respect to that  occurrence  unless the
insurer  fails or refuses to defend  and/or pay all claims,  losses and expenses
incurred by Landlord.  Notwithstanding the foregoing,  Landlord has the right to
make claims,  institute  legal  proceedings,  or otherwise seek redress  against
Tenant before the expiration of any statute of  limitations or other  limitation
on the time or manner in which  Landlord may seek redress  regardless of whether
or not an insurer is responding.  Tenant's  obligation to indemnify  Landlord as
provided in Sections  14.01 and 14.02 will  survive  the  expiration  or earlier
termination of this Lease.

Section  14.03  -  Landlord's  Liability.  Except  for its  intentional  acts or
negligence or the intentional  acts or negligence of its agents,  contractors or
licensees,  Landlord will not be responsible  or liable for any loss,  damage or
injury to the  Premises  or to any Person or property at any time on the Land or
in the Building or the Premises.

                                    Insurance


Section 15.01 - Tenant's Insurance.  Tenant agrees to provide, at its expense,
and to keep in force:

(a)  Comprehensive  general  liability  insurance  against  claims for  personal
     injury,  death and  property  damage  occurring  with  respect to  Tenant's
     occupancy of the Premises having primary  combined single limit coverage of
     at least $1,000,000 for bodily injury and property damage.

(b)  Casualty insurance against loss or damage to (i) all inventory,  furniture,
     furnishings and equipment other than Landlord's Fixtures owned,  controlled
     or in use by Tenant and  situated in the  Building,  (ii) all  Improvements
     made by Tenant pending completion and (iii) all Improvements made by Tenant
     which  Tenant is  required  to remove on the Lease  Termination  Date under
     Section 7.06,  under a so-called "All Risk" policy in an amount  sufficient
     to replace the same without allowance for depreciation,  if available,  and
     if not,  in the  amount  necessary  to avoid  the  effect  of  co-insurance
     provisions under the applicable policies.

(c)  Worker's  compensation  insurance for all Tenant's employees working in the
     Premises in an amount sufficient to comply with Legal Requirements.

(d)  Such  greater  limits and such other  insurance  and in such amounts as may
     from  time  to  time be  reasonably  required  by  Landlord  against  other
     insurable hazards which at the time are customarily  insured against in the
     case of buildings similarly situated and used.

Section 15.02 - General Insurance Provisions.

(a)  All  insurance  provided  for in  Section  15.01 will be written as primary
     policies  (without  "contribution" or "solely in excess of coverage carried
     by Lessor"  provisions)  and will be effected  under valid and  enforceable
     policies,  issued by insurers of  recognized  responsibility  authorized to
     write such insurance in Massachusetts  and having a Best's financial rating
     of B or better.  Not less than five (5) days  before the Term  Commencement
     Date,  and  thereafter  not less than ten (10) days  before the  expiration
     dates of the expiring policies  furnished under to Section 15.01,  binders,
     certificates  or other evidence of such insurance  satisfactory to Landlord
     bearing  notations  evidencing  the payment of premiums or  accompanied  by
     other evidence  satisfactory to Landlord of such payment, will be delivered
     by Tenant to Landlord.

(b)  Nothing in this Article 15 will prevent Tenant from taking out insurance of
     the kind and in the amounts provided for under this Article under a blanket
     insurance  policy or  policies  covering  other  properties  as well as the
     Premises.  Any policy or policies of blanket insurance (i) will specify, or
     Tenant will furnish  Landlord  with a written  statement  from the insurers
     specifying,  the amounts of the total insurance  allocated to the Premises,


<PAGE>


     which  amounts will not be less than the amounts  required by Section 15.01
     and will be  sufficient  to prevent  any of the  insureds  from  becoming a
     co-insurer within the terms of the applicable policy or policies, (ii) will
     contain  an  "Agreed  Amount"  clause as to the  Premises  and  (iii)  will
     otherwise  comply as to  endorsements  and coverage with the  provisions of
     this Article.

(c)  All policies of insurance  provided for in Section 15.01 will name Landlord
     and Tenant as the insured,  as their respective  interests may appear,  and
     also  the  Ground  Lessor  and any  mortgagee,  when  requested,  as  their
     respective  interests may appear,  except that Landlord,  the Ground Lessor
     and any such  mortgagee  will have no interest in the insurance on Tenant's
     personal  property.  Each such policy or certificate  issued by the insurer
     will,  to the extent  obtainable,  contain an agreement by the insurer that
     the insurance will not be cancelled without at least twenty (20) days prior
     written notice to Landlord and to any other named insureds. Landlord agrees
     not to carry any insurance  concurrent in coverage and  contributing in the
     event of loss with any insurance  required to be furnished by Tenant if the
     effect of such separate  insurance would be to reduce the protection or the
     payment to be made under Tenant's insurance.

Section  15.03 -  Landlord's  Insurance.  Landlord  agrees to cause the Building
(including  Landlord's  Fixtures but  excluding any  Improvements  and leasehold
improvements  (a) by any  tenant  prior to their  completion,  or (b)  which any
tenant may be required to remove  upon  termination  of its lease) to be insured
for the benefit of Landlord, the Ground Lessor and any mortgagee of Landlord, as
their respective interests may appear,  against loss or damage under a so-called
"All Risk"  policy in an amount equal to (i) the  replacement  value or (ii) the
amount  necessary  to  avoid  the  effect  of  co-insurance  provisions  of  the
applicable policies.  Landlord also agrees to maintain comprehensive form boiler
insurance,  rental value insurance and such other insurance  against such perils
and in such amounts as may be required by the Ground  Lessor or any mortgagee of
Landlord or as Landlord may consider prudent. The cost of such insurance will be
part of the Operating Expenses.

                              Waiver of Subrogation


Section  16.01 - Waiver of  Subrogation.  If available,  all insurance  policies
carried by either party covering the Building and/or the Premises will contain a
clause or endorsement  expressly waiving any right on the part of the insurer to
make any claim  against  the other  party and  against  the Ground  Lessor.  The
parties  agree to use  reasonable  efforts to insure  that their  policies  will
include such waiver clause or endorsement.

Section  16.02 - Waiver of Rights.  Landlord  and Tenant  each waive all claims,
causes of action and rights of recovery against the other and against the Ground
Lessor and their respective partners,  agents,  officers and employees,  for any
loss or damage to persons,  property or  business  which  occurs on or about the
Premises or the Building and results  from any of the perils  insured  under any
policy of insurance  maintained by Landlord and/or Tenant,  regardless of cause.
This waiver includes the negligence and  intentional  wrongdoing of


<PAGE>


either  party  and  their  respective  agents,  officers  and  employees  but is
effective only to the extent of recovery,  if any,  under any such policy.  This
waiver  will be void to the extent that any such  insurance  is  invalidated  by
reason of this waiver.

                             Damage and Restoration


Section 17.01 - Substantial  Damage. If the Building is damaged by fire or other
casualty,  Tenant  agrees to give prompt  written  notice to  Landlord.  If as a
result  of  fire  or  other  casualty,  (i)  the  Building  is so  damaged  that
substantial  alteration or reconstruction of the Building is, in Landlord's sole
opinion,  required (whether or not the Premises have been damaged),  or (ii) the
Ground Lease is terminated, or (iii) any mortgagee of the Building requires that
all or a substantial portion of insurance proceeds payable be used to retire the
mortgage  debt,  Landlord  may,  at its option,  terminate  this Lease by giving
notice to Tenant within sixty (60) days after the date of the damage. If, within
sixty (60) days after the date of the damage, Landlord does not begin to restore
the  Building as provided in Section  17.02 or notify  Tenant of its election to
terminate  this  Lease,  Tenant may  terminate  this  Lease by giving  notice to
Landlord within ten (10) days after the expiration of the sixty (60) day period.
If this Lease is  terminated  by Landlord or Tenant as provided in this  Section
17.01, Rent will be abated as of the date of the damage.

Section  17.02 -  Restoration.  If  Landlord  does not  terminate  this Lease as
provided in Section  17.01  within sixty (60) days after the date of the damage,
Landlord  agrees to begin to restore  the  Building  to  substantially  the same
condition  in which it was  immediately  before  the  damage,  and,  subject  to
Unavoidable  Delays,  to continue the  restoration  with  reasonable  diligence.
Landlord's  restoration work will include Landlord's Fixtures,  the scope of the
work done by Landlord in  originally  finishing  the  Premises  according to the
Working Drawings and subsequent Improvements made by Tenant under the provisions
of Section 7.06 which are to remain part of the  Premises.  Landlord will not be
required to  rebuild,  repair,  or replace  (i) any part of Tenant's  furniture,
furnishings or equipment,  or (ii) any Improvements  made by Tenant which Tenant
is required to remove on the Lease Termination Date under Section 7.06. Landlord
will not be liable for any inconvenience or annoyance to Tenant or injury to the
business of Tenant  resulting  from the damage to or the repair of the Building,
except that  Landlord  will allow Tenant a fair  reduction of Rent to the extent
the  Premises are unfit for  occupancy  from the date of the  occurrence  of the
damage to a date thirty (30) days after completion of Landlord's repairs.

Section 18.01 - Total Taking.  If there is a Total Taking,  then this Lease 


<PAGE>


will  terminate  as of the  earlier  to  occur  of (i) the  date  when  physical
possession  of  the  Building  or  the  Premises  is  taken  by  the  condemning
Governmental  Authority  or (ii) the date  when  title  vests in the  condemning
Governmental Authority.

Section 18.02 - Partial  Taking.  If there is a Taking of the Premises  which is
not a Total Taking, Landlord may terminate this Lease by giving notice to Tenant
within sixty (60) days after receiving notice of the Taking, in which event this
Lease will  terminate  as of the earlier to occur of (i) the date when  physical
possession  of  such  portion  of  the  Premises  is  taken  by  the  condemning
Governmental  Authority  or (ii) the date  when  title  vests in the  condemning
Governmental  Authority.  If this Lease is not  terminated,  Rent will be abated
from the date the  Premises  are  rendered  unfit  for  occupancy  by an  amount
representing  that part of the Rent  properly  allocable  to the  portion of the
Premises taken, and Landlord will, at Landlord's  expense,  restore the Building
and the  Premises to  substantially  their  former  condition to the extent that
restoration,  in Landlord's judgment,  may be feasible.  Landlord's  restoration
work will not exceed the scope of Tenant Fit-up as shown in the Working Drawings
and subsequent  Improvements made by Tenant under the provisions of Section 7.06
which are to remain part of the Premises.

Section 18.03 - Awards and Proceeds. All proceeds payable in respect of a Taking
will be the property of Landlord.  Tenant hereby  assigns to Landlord all rights
of Tenant in or to such  awards  and  proceeds,  provided  that  Tenant  will be
entitled to separately  petition the  condemning  authority for a separate award
for its moving  expenses and trade  fixtures  but only if such a separate  award
will not diminish the amount of award or proceeds payable to Landlord.

                                 Quiet Enjoyment


Section 19.01 - Landlord's  Covenant.  Landlord covenants that it has good title
to the Premises and the Common Areas, subject to the Permitted  Exceptions,  and
that it has  sufficient  authority  to enter  into  this  Lease.  Landlord  also
covenants that if Tenant pays the Rent and performs all of its obligations under
this Lease, subject to the Permitted Exceptions,  it will quietly have and enjoy
the  Premises  during  the Lease  Term,  without  interference  from any  Person
lawfully claiming under Landlord or by paramount title.  Landlord agrees that it
will pay and perform all of its obligations under the Ground Lease.

Section 19.02 - Subordination and Non-Disturbance.  This Lease is subordinate to
(i) the Ground  Lease and (ii) any mortgage now or hereafter on the Building and
to  each  advance  made  under  any  such   mortgage,   and  to  all   renewals,
modifications,  consolidations,  replacements  and  extensions of such mortgage.
This Section 19.02 is self-operative  and no further instrument of subordination
will be  required,  provided  that before a future  subordination  is  effective
Landlord  will  cause the  mortgagee  or Ground  Lessor to  deliver  to Tenant a
non-disturbance agreement, binding upon itself and any successor in interest, to
the effect that no  foreclosure  of the  mortgage or  termination  of


<PAGE>


the Ground Lease will disturb the  possession of Tenant under this Lease so long
as no Event of Default exists.  In confirmation  of such  subordination,  Tenant
agrees to execute and deliver  promptly  any  certificate  that  Landlord or the
Ground Lessor or any  mortgagee  may request.  If any mortgagee or Ground Lessor
succeeds to the  interest of Landlord  and agrees to  recognize  the interest of
Tenant  under this Lease,  Tenant  agrees to attorn to such  mortgagee or Ground
Lessor,  to recognize  such  mortgagee  or Ground  Lessor as its landlord and to
execute any instrument  reflecting its  attornment  and  recognition  reasonably
requested by such mortgagee or Ground Lessor.

Section 19.03 - Notice to Mortgagee and Ground Lessor.  No act or failure to act
on the part of  Landlord  which  would  entitle  Tenant  under the terms of this
Lease, or by law, to be relieved of Tenant's  obligations  under or to terminate
this Lease,  will result in a release or  termination  of such  obligations or a
termination  of this Lease  unless  (i) Tenant  first  gives  written  notice of
Landlord's  act or failure to act to Landlord's  first  mortgagee of record,  if
any, and to the Ground Lessor  specifying  the act or failure to act on the part
of Landlord  which could or would give basis to  Tenant's  rights;  and (ii) the
mortgagee or Ground  Lessor,  after receipt of such notice,  fails or refuses to
correct or cure the condition  complained of within a reasonable  time.  Nothing
contained in this Section  19.03 will be deemed to impose any  obligation on any
mortgagee or Ground Lessor to correct or cure any condition.  "Reasonable  time"
means a period of not less than thirty (30)  Business  Days and includes (but is
not limited to) a reasonable  time to obtain  possession  of the Building if the
mortgagee or Ground Lessor  elects to do so and a reasonable  time to correct or
cure the  condition  if the  condition  is  determined  to exist.  Tenant has no
obligation  to give notice under this Section  19.03 until the  mortgagee or the
Ground Lessor has given Tenant notice of its interest as such and the address to
which notices under this Section 19.03 are to be sent.

Section 19.04 - Other Provisions Regarding Mortgagees. If this Lease or the Rent
is  assigned to a mortgagee  as  collateral  security  for any  obligation,  the
mortgagee will not be deemed to have assumed any of Landlord's obligations under
this Lease solely as a result of the assignment.  A mortgagee to whom this Lease
has been assigned will be deemed to have assumed such obligations only if (i) by
the terms of the  assignment  the  mortgagee  specifically  elects to assume the
obligations, or (ii) the mortgagee has (a) foreclosed its mortgage, (b) accepted
a deed in substitution of foreclosure,  or (c) taken possession of the Premises.
Even if the mortgagee assumes the obligations of Landlord, the mortgagee will be
liable for  breaches  of any of  Landlord's  obligations  only to the extent the
breaches occur during the period of ownership by the mortgagee after foreclosure
(or any conveyance by a deed in substitution of foreclosure) or after entry, and
the  mortgagee  will  have  no  liability  for any  act or  omission  or for any
obligations incurred by any prior Landlord,  including liability with respect to
any Security Deposit except to the extent actually received by such mortgagee.

                           Defaults; Events of Default


Section 20.1 - Defaults. The following will (i) if any requirement for notice 


<PAGE>


or lapse of time has not been met, constitute Defaults, and (ii) if there are no
such requirements or if such  requirements  have been met,  constitute Events of
Default:

(a)  The  failure of Tenant to pay Rent when due,  and the  continuation  of the
     failure for a period of ten (10) days after notice from Landlord specifying
     the failure;

(b)  The failure of Tenant to perform any of its  obligations  under this Lease,
     other than its obligation to pay Rent, and the  continuation of the failure
     for a period of twenty (20) days after notice from  Landlord  specifying in
     reasonable detail the nature of the failure;

(c)  The  failure  of  Tenant  to pay  Rent  when due or to  perform  any of its
     obligations  under this Lease,  if Landlord has given Tenant  notice of the
     same or similar  failure at least twice during the twelve (12) month period
     preceding the date on which the Rent or performance was due.

(d)  The  occurrence  with respect to Tenant or any  Guarantor of one or more of
     the following  events:  the death,  dissolution,  termination  of existence
     (other  than by  merger or  consolidation),  insolvency,  appointment  of a
     receiver  for all or  substantially  all of its  property,  the making of a
     fraudulent  conveyance or the execution of an assignment or trust  mortgage
     for the  benefit  of  creditors  by it,  or the  filing  of a  petition  of
     bankruptcy or the  commencement of any proceedings by or against it under a
     bankruptcy,  insolvency  or  other  law  relating  to  the  relief  or  the
     adjustment of indebtedness,  rehabilitation  or  reorganization of debtors;
     provided  that if such  petition  or  commencement  is  involuntarily  made
     against  it and is  dismissed  within  sixty  (60) days of the date of such
     filing  or  commencement,  such  events  will  not  constitute  an Event of
     Default;

(e)  The issuance of any  execution or  attachment  against  Tenant or any other
     occupant  of the  Premises as a result of which the  Premises  are taken or
     occupied by a Person other than Tenant; and

(f)  The  cancellation  of,  refusal to review or denial of liability  under any
     insurance policy relating to the Premises as a result of the Premises being
     unoccupied.

Section 20.2 - Tenant's Best  Efforts.  If the Default of which  Landlord  gives
notice is of such a nature that it cannot be cured within twenty (20) days, then
the Default  will not be deemed to continue so long as Tenant,  after  receiving
notice of the Default, begins to cure the Default as soon as reasonably possible
and continues to take all steps  necessary to complete the curing of the Default
within time which, under all prevailing circumstances, is reasonable. No Default
will be deemed to  continue  so long as Tenant is acting to cure the  Default in
good faith or is delayed in or  prevented  from  curing the Default by reason of
Unavoidable Delays.

                     Landlord's Remedies; Damages on Default


<PAGE>


Section 21.01 - Landlord's Remedies.  Landlord may, at its option:

(a)  Whenever an Event of Default exists,  give Tenant a notice terminating this
     Lease on a date  specified  in the  notice.  On the date  specified  in the
     notice,  this  Lease and all  rights of Tenant  under  this  Lease will end
     without  further  notice or lapse of time,  but Tenant will  continue to be
     liable to Landlord as provided in this Article 21.

(b)  If an Event of Default  results from Tenant's  failure to pay Tenant's Cost
     as  required  by Section  7.01 and the Work  Letter,  in  addition to or in
     substitution  of the other  remedies  available to Landlord,  refuse Tenant
     access to the Premises.  In such event the Term  Commencement  Date will be
     the  earlier  of (i) the date  determined  under  Section  7.04 or (ii) the
     Substantial Completion Date.

(c)  If an Event of Default  results from  Tenant's  failure to pay a charge for
     Additional Services,  without further notice to Tenant,  discontinue any or
     all Additional Services.

Section 21.02 - Possession.  Upon  termination of this Lease as the result of an
Event of Default,  Tenant agrees to leave the Premises  peacefully and surrender
possession  to Landlord as provided in Section  9.08.  Landlord may, at any time
after any  termination  of this  Lease and  without  further  notice,  enter the
Premises  and recover  possession  by summary  proceedings  or any other  manner
permitted by law, and may remove  Tenant and all other Persons and property from
the  Premises.  After  termination  of this Lease,  Landlord will be entitled to
receive all rental income from the Premises.

Section 21.03- Right to Relet. After termination of this Lease as a result of an
Event of Default, Landlord may relet all or any part of the Premises in the name
of Landlord or  otherwise,  for such term (which may be greater or less than the
period which would have  constituted  the balance of the Lease Term) and on such
conditions  (which may include  concessions  or free rent) as  Landlord,  in its
reasonable discretion, may determine.  Landlord agrees to use reasonable efforts
but will not be liable  for  failure  to relet the  Premises  or for  failure to
collect any rent due upon reletting,  and Landlord will not be obligated to show
the Premises in preference to other space available in the Building.

Section  21.04 - Survival  of  Covenants,  Etc. If this Lease is  terminated  as
provided in Section 21.01:

(a)  The  termination  will not  relieve  Tenant of its  obligations  under this
     Lease,  which  obligations will survive the  termination.  Tenant agrees to
     indemnify  Landlord against all claims,  losses and expenses arising out of
     the termination.

(b)  At the time of termination, Tenant agrees to pay to Landlord the Rent up to
     the date of termination.  Tenant also agrees to pay to Landlord, on demand,
     as liquidated damages for Tenant's Default, the excess of

     (1)  the total Rent that would have been payable under this Lease by Tenant
          from the date of the  termination  until the Stated  Expiration  Date,
          over


<PAGE>


     (2)  the fair and  reasonable  rental  value of the  Premises  for the same
          period  reduced by  Landlord's  reasonable  estimate of expenses to be
          incurred in connection with reletting the Premises, including, without
          limitation,  all  repossession  costs,  brokerage  commissions,  legal
          expenses,  reasonable  attorneys' fees, alteration costs, and expenses
          of preparation for reletting.

(c)  If all or part of the Premises are relet by Landlord,  before  presentation
     of proof of such liquidated  damages to any court,  commission or tribunal,
     the amount of rent reserved upon the  reletting  will be, prima facie,  the
     fair and reasonable  rental value for the part or the whole of the Premises
     relet during the term of the reletting.

(d)  Nothing  contained in this Section  21.04 will limit or prejudice the right
     of  Landlord  to prove and  obtain as  liquidated  damages by reason of the
     termination,  an amount equal to the maximum allowed by any statute or rule
     of law in effect at the time when, and governing the  proceedings in which,
     such damages are to be proved, whether or not such amount is greater, equal
     to, or less than the amount determined as provided in clause (b) above.

Section 21.05 - Right to Equitable Relief. If a Default occurs, Landlord will be
entitled to enjoin the  Default  and may invoke any remedy  allowed at law or in
equity as though  re-entry,  summary  proceedings  and other  remedies  were not
provided for in this Lease.

Section  21.06 - Right to Self Help;  Interest On Overdue  Rent.  If an Event of
Default occurs,  Landlord has the right,  but not the  obligation,  to enter the
Premises   and  to  perform   any   obligation   of  Tenant   under  this  Lease
notwithstanding the fact that no specific provision for substituted  performance
by Landlord is made in this Lease.  In performing the  obligation,  Landlord may
make any  payment of money or perform  any other act.  The total of (i) all sums
paid by Landlord  (ii)  interest (at the rate of 1-1/2% per month or the highest
rate  permitted  by law,  whichever is less) on such sums plus all Rent not paid
when due and  (iii) all  expenses  in  connection  with the  performance  of the
obligation  by Landlord,  will be deemed to be Rent under this Lease and payable
to Landlord on demand. Landlord may exercise its rights under this Section 21.05
without  waiving  any other of its rights or  releasing  Tenant  from any of its
obligations under this Lease.

                                     Notices


Section 22.01 - Notices and Communications.  All notices,  demands, requests and
other  communications  provided  for or  permitted  under  this Lease must be in
writing and be delivered by hand or sent by telecopy,  nationally recognized and
reputable   overnight  delivery  service,   express  mail,   certified  mail  or
first-class mail, postage prepaid, to the parties, respectively at the following
addresses:

(a)  if to  Landlord,  at the address  stated in Section  1.01 (or at such other
     address as Landlord  designates in writing to Tenant),  with a copy to such


<PAGE>


     Persons as Landlord designates in writing to Tenant, or

(b)  if to  Tenant,  at the  address  stated in  Section  1.01 (or at such other
     address as Tenant  designates in writing to Landlord),  with a copy to such
     Persons as Tenant designates in writing to Landlord.

Section 22.02 - When  Effective.  Any  communication  provided for in this Lease
will become  effective  only when  received or deemed  received by the Person to
whom it is given. If it is mailed by express,  certified or first-class mail, it
will be deemed to be received on (i) the second  Business Day after being mailed
or (ii) the day of its receipt,  whichever is earlier. If given by telecopy,  it
will be deemed received when confirmation of complete receipt is received by the
transmitting  person during normal  business  hours on a Business Day, or on the
next Business Day if confirmation is received after normal business hours.

                                     Waivers


Section 23.01 - No Waivers. Failure of Landlord or Tenant to complain of any act
or omission on the part of the other no matter how long the act or omission  may
continue,  will not be deemed to be a waiver by either Landlord or Tenant of any
of its rights  under this  Lease.  No waiver by  Landlord or Tenant at any time,
expressed  or  implied,  of the  breach of any  provision  of this Lease will be
deemed a waiver of a breach of any other provision of this Lease or a consent to
any  subsequent  breach of the same or any other  provision.  No  acceptance  by
Landlord of any partial payment will  constitute an accord or  satisfaction  but
will only be deemed a partial payment on account.  None of Tenant's  obligations
under this Lease and no  Default or Event of Default  may be waived or  modified
except in writing by Landlord.


                                   ARTICLE 24

                                Security Deposit


Section  24.01 -  Security  Deposit.  Tenant has  deposited  with  Landlord  the
Security  Deposit in the amount,  if any, stated in Section 1.01.  Landlord will
hold the Security  Deposit as security for the payment or  performance by Tenant
of its  obligations  under this Lease and not as a prepayment of Rent.  Landlord
may commingle the Security  Deposit with other funds of Landlord.  Landlord will
not be liable to Tenant for the payment of  interest.  Landlord  may expend such
amounts  from the  Security  Deposit as may be  necessary to cure any Default or
Event of Default and, in such case,  Tenant agrees to pay to Landlord the amount
expended, on demand.  Landlord may assign the Security Deposit to any subsequent
owner of the Building and  thereafter  Landlord will have no liability to Tenant
with respect to the Security  Deposit.  As soon as reasonably  practicable after
the Lease Termination Date, Landlord agrees (i) to inspect the Premises, (ii) to
make such  payments  from the  Security  Deposit as may be required to reimburse
itself for unpaid Rent and all 


<PAGE>


expenses  arising out of the termination of the Lease and reletting the Premises
and (iii) if no Default  or Event of Default  has  occurred  or exists,  pay the
balance of the Security Deposit to Tenant.

                               General Provisions


Section 25.01 - Unavoidable  Delays. If Landlord or Tenant is delayed,  hindered
in or prevented  from the  performance  of any act required  under this Lease by
reason of Unavoidable  Delays,  then  performance of the act will be excused for
the period of the delay and the period  for the  performance  of the act will be
extended for a period equivalent to the period of the delay.

Section  25.02 - Estoppel  Certificates.  Tenant  agrees to deliver to  Landlord
within  five (5)  Business  Days after the Term  Commencement  Date an  estoppel
certificate  substantially  in the form of Exhibit D. Within  five (5)  Business
Days after receipt of a request from  Landlord,  Tenant agrees to deliver to any
prospective  purchaser,  mortgagee or other  Person  specified in the request an
estoppel  certificate  substantially  in the form of  Exhibit D or in such other
form as the purchaser,  mortgagee or other Person may reasonably prescribe. Each
estoppel  certificate will be (i) signed by a duly authorized  representative of
Tenant,  (ii)  delivered  without  charge to the party  requesting  it and (iii)
binding as to its contents on Tenant.

Section 25.03 - Right to Relocate.  Landlord  may, at its option,  upon not less
than two (2) months prior notice to Tenant, relocate Tenant (effective as of the
date  specified  in the  notice) to other  space in the  Building  or in another
building  in the  Park  having  Improvements  comparable  in type,  quality  and
quantity,   a   substantially   similar   configuration   and  a  rentable  area
approximately the same as the Premises. Landlord agrees to place the other space
in  substantially  the same condition as the Premises are then in and to pay all
costs  associated  with the  relocation.  If  Tenant  is  relocated  under  this
provision (i) the other space will be  substituted  for the Premises  under this
Lease (ii) the terms and  provisions of this Lease will remain in full force and
effect and (iii) Tenant  agrees (a) to relocate as requested by Landlord and (b)
to  execute  all  documents  (including  but not  limited  to a  termination  or
amendment of this Lease with respect to the Premises) as Landlord may reasonably
request.

Section 25.04 - Holding Over.  If Tenant  occupies the Premises  after the Lease
Termination  Date without  having  entered into a new lease of the Premises with
Landlord,  Tenant  will be a  tenant-at-sufferance  only,  subject to all of the
provisions of this Lease at twice the then  effective  Basic Rent.  Such holding
over, even if with the consent of Landlord,  will not constitute an extension or
renewal of this Lease.

Section 25.05 - Governing Law. This Lease and the  performance of its provisions
will  be  governed  and  construed  under  the  laws  of  the   Commonwealth  of
Massachusetts.

Section  25.06 -  Partial  Invalidity.  If any  provision  of this  Lease or its


<PAGE>


application   to  any  Person  or   circumstance   is  held  to  be  invalid  or
unenforceable,  the remainder of this Lease, or the application of the provision
to Persons or  circumstances  other than those as to which it is held invalid or
unenforceable,  will not be affected,  and each  provision of this Lease will be
enforced to the fullest extent permitted by law.

Section  25.07 - Notice of Lease.  At the  request of either one,  Landlord  and
Tenant agree to execute  promptly  duplicate  originals of a statutory notice of
lease,  in recordable  form,  setting forth a description  of the Premises,  the
Lease Term and any other terms of this Lease,  except the rental provisions,  as
may be required by law or as either party may request.

Section 25.08 - Interpretation.  The section headings used in this Lease are for
reference and convenience only, and do not enter into the interpretation of this
Lease.  This  Lease may be signed in several  counterparts,  each of which is an
original,  but all of which constitute a single instrument.  The term "Landlord"
means only the owner at the time of the Building.  Upon any sale of the Building
or  assignment  (other than as  collateral  security for an  obligation)  of the
interest of Landlord in this Lease,  Landlord  will be relieved of all liability
under this Lease and its  successor in interest  and/or assign will be deemed to
be Landlord so long as it owns the  Building.  The  liability of Landlord  under
this Lease is limited to Landlord's interest in the Building.

Section  25.09 - Consents.  Except for the consents of Landlord  required  under
Section  7.06 and Article 13,  consents or  approvals  required or  requested of
either Landlord or Tenant shall not be unreasonably withheld or delayed.

Section 25.10 - Entire  Agreement;  Changes.  All prior  agreements  between the
parties  are merged  within this  Lease,  which  alone  fully  states the entire
understanding  and  agreement of the  parties.  This Lease may not be changed or
terminated  orally or in any manner  other than by an  agreement  in writing and
signed by the party against whom  enforcement  of the change or  termination  is
sought.

Section 25.11 - Binding Effect.  The provisions of this Lease are binding on and
inure to the benefit of Landlord,  its successors and assigns,  and Tenant,  its
successors and assigns and any Person claiming under Tenant.

Section  25.12 - Time of the  Essence.  Any  provision  of law or  equity to the
contrary  notwithstanding,  it is  agreed  that time is of the  essence  of this
Lease.

                       BIOJECT MEDICAL TECHNOLOGIES, INC.

                               RIDER AND ADDENDUM

to which  this  Rider and  Addendum  is  attached  is  modified  and  amended by
incorporation of the following additional provisions:

A. The  following  provisions  (i) will  continue  in effect so long as Teachers
Insurance  and  Annuity  Association  of America  ("TIAA"),  its  successors  or
assigns,  holds a mortgage  of the  Building  and will be  considered  permanent
amendments  to this Space  Lease upon the  foreclosure  or granting of a deed in
lieu of foreclosure  of any such  mortgage,  but (ii) will cease to be in effect
automatically upon the discharge of any such mortgage:

     A-1. Occupancy  Arrangements.  Notwithstanding the provisions of Article 13
to the  contrary,  Tenant  agrees  that  Tenant may not enter into an  Occupancy
Arrangement  with a Person who is  affiliated  with Tenant unless (a) the Person
has a net worth,  determined in accordance  with generally  accepted  accounting
principles, at least equal to Tenant's net worth and (b) the Person agrees to be
bound  by  the  obligations  of  Tenant  under  the  Lease,  including,  without
limitation,  the covenant against further Occupancy Arrangements.  Tenant agrees
not to enter into any  Occupancy  Arrangement  which  provides for Rent based in
whole or in part on the net  income or profits  derived  by any Person  from the
Premises, and any such Occupancy Arrangement will be void, provided that nothing
in this paragraph A-1 will be deemed to prohibit  Occupancy  Arrangements  which
provide for Rent based upon a percentage of sales or receipts.

     A-2.  Hazardous  Materials.  In  addition to and not in  limitation  of the
provisions   of   Section   10.04,   Tenant   agrees  to   execute   affidavits,
representations  and  certificates  from  time  to time  at  Landlord's  request
concerning  Tenant's  best  knowledge  and  belief  regarding  the  presence  of
Hazardous Substances on the Premises.

     A-3. Tenant's  Insurance.  In addition to the limits required under Section
15.01, Tenant agrees to keep in force comprehensive  general liability insurance
against claims for personal  injury,  death and property  damage  occurring with
respect to Tenant's  occupancy of the Premises  having primary  combined  single
limit coverage of at least $3,000,000 per occurrence.

     A-4. Restoration.  Notwithstanding the provisions of Article 17, Landlord's
obligation to restore the Building following damage by fire or other casualty is
limited  to  the  amount  of  insurance   proceeds  available  to  Landlord  for
restoration purposes.

     A-5  Partial  Taking.  Notwithstanding  the  provisions  of Section  18.02,
Landlord's  obligation  to restore the  Building  following a Partial  Taking is
limited  to the  amount of  condemnation  proceeds  available  to  Landlord  for
restoration purposes.

B. The following provisions will continue in effect throughout the Lease Term:

     B-1 Delete the definition of "Substantial  Completion  Date" and insert the
following:  The date on which the  improvements  to be  constructed  by Landlord
pursuant to B-3 of this Rider are completed.

obligation to pay the Basic Rent and notwithstanding  Article 6 of this Lease or
any other term or provision of this Lease,  no Additional Rent shall be owing to
the Landlord.

     B-3 The Exclusive  Premises shall be remodeled for Tenant's use at the cost
of Landlord as follows:

          e.  Install  new  8-foot  frame  hood and  associated  mechanical  and
     plumbing systems in Lab 430A.

     B-4 Upon execution of this Lease, Tenant shall pay $7,500.00 to Landlord to
be applied to the cost of the frame hood to be installed by Landlord pursuant to
B-3 of this Rider.  If Tenant and Landlord enter a new lease or lease  extension
of at least  one (1) year in  length,  Landlord  agrees  to  provide a credit to
Tenant  against  rent due under the new lease or the  extension in the amount of
$7,500.00.

     B-5 Landlord  agrees to clean the  Premises,  repair any damaged  surfaces,
repaint  walls as needed,  and ensure  that all  building  systems  serving  the
Premises are in working order.

                        BIOJECT MEDICAL TECHNOLOGIES INC.
                       RESTATED 1992 STOCK INCENTIVE PLAN

Restated Effective April 15, 1998

1. Purpose.  The purpose of this Restated 1992 Stock Incentive Plan (the "Plan")
is to enable  Bioject  Medical  Technologies  Inc., an Oregon  corporation  (the
"Company"),  to attract  and  retain the  services  of (a)  selected  employees,
officers and directors of the Company or of any parent or subsidiary corporation
of the Company, and (b) selected nonemployee agents,  consultants,  advisers and
independent contractors of the Company or any parent or subsidiary.

2. Subject to the Plan. Subject to adjustment as provided below and in paragraph
11, up to 3,650,000  shares of Common Stock of the Company (the "Shares")  shall
be offered  and issued  under the Plan.  No more than  3,000,000  of such Shares
offered and issued  under the Plan may be offered and issued  pursuant to grants
under the Plan of  Incentive  Stock  Options as  defined  in Section  422 of the
Internal Revenue Code of 1986, as amended (the "Code").  If an option or a stock
appreciation  right granted under the Plan expires,  terminates or is cancelled,
the unissued  Shares  subject to such option or stock  appreciation  right shall
again be  available  under the Plan.  If Shares sold or awarded as a bonus under
the Plan are forfeited to the Company or repurchased by the Company,  the number
of Shares forfeited or repurchased shall again be available under the Plan.

3. Effective Date and Duration of Plan.

     (a) Effective  Date.  The Plan shall become  effective  when adopted by the
Board of Directors  of the Company (the  "Board").  However,  no option  granted
under  the Plan  shall  become  exercisable  until the Plan is  approved  by the
affirmative vote of the holders of a majority of the Common Stock of the Company
represented at a shareholder meeting at which a quorum is present,  and any such
awards under the Plan prior to such approval shall be conditioned on and subject
to such approval.  Subject to this  limitation,  options and stock  appreciation
rights  may be  granted  and  Shares may be awarded as bonuses or sold under the
Plan at any time after the effective date and before termination of the Plan.

     (b) Duration.  No options or stock appreciation rights may be granted under
the Plan, no stock  bonuses may be awarded under the Plan,  and no Shares may be
sold pursuant to paragraph 8 of the Plan on or after July 29, 2002. However, the
Plan shall continue in effect until all Shares  available for issuance under the
Plan have been issued and all restrictions on such Shares have lapsed. The Board
may suspend or terminate  the Plan at any time,  except with respect to options,
stock  appreciation  rights and Shares subject to restrictions  then outstanding
under the Plan.  Termination  shall not affect any  outstanding  options,  stock
appreciation  rights,  any  right of the  Company  to  repurchase  Shares or the
forfeitability of Shares issued under the Plan.

4. Administration.

     (a) The Plan shall be  administered  by a committee  appointed by the Board
consisting of not less than two directors (the 

<PAGE>

"Committee").  The Committee  shalldetermine and designate from time to time the
individuals  to whom awards  shall be made,  the amount of the  awards,  and the
other terms and conditions of the awards; provided, however, that only the Board
may amend or terminate  the Plan as provided in paragraphs 3 and 14. At any time
when the officers and  directors of the Company are subject to Section  16(b) of
the Securities  Exchange Act of 1934 (the "Exchange  Act"),  the Committee shall
consist solely of "non-employee"  directors as such term is defined from time to
time in SEC Rule  16b-3(b)(3)(i)  or successor  rule. No member of the Committee
shall be eligible  to receive any award under the Plan while such person  serves
as a Committee member, except pursuant to paragraph 10.

     (b) Subject to the  provisions of the Plan,  the Committee may from time to
time adopt and amend rules and  regulations  relating to  administration  of the
Plan,  advance  the lapse of any  waiting  period,  accelerate  any  vesting  or
exercise  date,  waive or modify any  restriction  applicable to Shares  (except
those  restrictions  imposed  by law) and make all other  determinations  in the
judgment of the Committee  necessary or desirable for the  administration of the
Plan.  The  interpretation  and  construction  of the provisions of the Plan and
related agreements by the Committee shall be final and conclusive. The Committee
may correct any defect or supply any omission or reconcile any  inconsistency in
the Plan or in any  related  agreement  in the manner and to the extent it shall
deem expedient to carry the Plan into effect, and it shall be the sole and final
judge of such expediency.

5. Types of Awards; Eligibility.  The Committee may, from time to time, take the
following actions under the Plan: (i) grant Incentive Stock Options, as provided
in  paragraph  6(b);  (ii) grant  options  other than  Incentive  Stock  Options
("Nonstatutory  Stock Options") as provided in paragraph 6(c); (iii) award stock
bonuses as provided in paragraph 7; (iv) sell Shares as provided in paragraph 8;
and (v) grant stock  appreciation  rights as provided in  paragraph  9. Any such
awards  may be made to  employees  (including  employees  who  are  officers  or
directors)  of the  Company or of any parent or  subsidiary  corporation  of the
Company,  and to other  individuals  described in paragraph 1 who the  Committee
believes have made or will make an important  contribution to the Company or its
parent or subsidiaries; provided, however, that only employees of the Company or
a parent or  subsidiary  shall be eligible to receive  Incentive  Stock  Options
under the Plan,  and,  provided  further,  that  directors who are not employees
shall receive  awards only pursuant to paragraph 10. The Committee  shall select
the  individuals to whom awards shall be made and shall specify the action taken
with respect to each  individual to whom an award is made under the Plan. At the
discretion of the Committee, an individual may be given an election to surrender
an award in exchange for the grant of a new award.

6. Option Grants

     (a) Grant. Each option granted under the Plan shall be evidenced by a stock
option agreement in such form as the Committee shall prescribe from time to time
in accordance  with the Plan.  With respect to each option grant,  the Committee
shall  determine the number of Shares  subject to the option,  the option price,
the  period  of the  option,  and the time or times at which the  option  may be
exercised and whether the option is an Incentive  Stock Option or a Nonstatutory
Stock Option.

<PAGE>

     (b) Incentive Stock Options. Incentive Stock Options granted under the Plan
shall be subject to the following terms and conditions:

          (i) No employee may be granted  Incentive Stock Options under the Plan
     such that the  aggregate  fair market value,  on the date of grant,  of the
     Shares with respect to which  Incentive  Stock Options are  exercisable for
     the first time by that employee during any calendar year under the Plan and
     under any other  incentive stock option plan (within the meaning of Section
     422 of the Code) of the Company or of any parent or subsidiary  corporation
     of the Company exceeds $100,000.

          (ii) An  Incentive  Stock  Option may be granted  under the Plan to an
     employee possessing more than 10 percent of the total combined voting power
     of all  classes  of stock of the  Company  or of any  parent or  subsidiary
     corporation of the Company only if the option price is at least 110 percent
     of the fair market value, as described in paragraph 6(b)(iv), of the Shares
     subject  to the  option on the date it is  granted,  and the  option by its
     terms is not exercisable more than five years from the date of grant.

          (iii) Subject to paragraphs 6(b)(ii) and 6(d), Incentive Stock Options
     granted under the Plan shall continue in effect for the period fixed by the
     Committee,  except that no Incentive Stock Option shall be exercisable more
     than 10 years from the date of grant.

          (iv) The option price per Share shall be  determined  by the Committee
     at the time of grant. Subject to paragraph 6(b)(ii), the option price shall
     not be less than 100 percent of the fair market value of the Shares covered
     by the Incentive  Stock Option at the date the option is granted.  The fair
     market value shall be deemed to be the average of the closing bid and asked
     prices for the Common  Stock of the  Company as  reported  on the  National
     Association of Securities  Dealers,  Inc. Automated Quotation System on the
     day preceding  the day the option is granted,  or if there has been no sale
     on that date, on the last preceding date on which a sale occurred,  or such
     other  reported  value  of the  Common  Stock  of the  Company  as shall be
     specified by the Committee.

          (v) The  Committee may at any time without the consent of the optionee
     convert an Incentive Stock Option into a Nonstatutory Stock Option.

     (c) Nonstatutory Stock Options. Nonstatutory Stock Options shall be subject
to the following additional terms and conditions:

          (i)  The  option  price  for  Nonstatutory   Stock  Options  shall  be
     determined by the Committee at the time of grant.  The option price may not
     be less than 75 percent of the fair market  value of the Shares  covered by
     the  Nonstatutory  Stock Option on the date of grant. The fair market value
     of the Shares  covered by a  Nonstatutory  Stock Option shall be determined
     pursuant to 

<PAGE>

     paragraph 6(b)(iv).

          (ii) Nonstatutory  Stock Options granted under the Plan shall continue
     in effect for the period fixed by the Committee.

     (d) Exercise of Options.  Except as provided in paragraphs  6(e) and (f) or
as  determined  by the  Committee,  no  option  granted  under  the  Plan may be
exercised  unless at the time of such exercise the optionee is employed by or in
the  service  of the  Company  or any parent or  subsidiary  corporation  of the
Company  and  shall  have  been  so  employed  or  have  provided  such  service
continuously  since the date such  option  was  granted.  Absence on leave or on
account of illness or disability under rules  established by the Committee shall
not, however,  be deemed an interruption of employment for purposes of the Plan.
Unless  otherwise  determined  by the  Committee,  vesting of options  shall not
continue  during an absence  on leave  (including  an  extended  illness)  or on
account of disability. Except as provided in paragraphs 6(f), 11 and 12, options
granted  under  the Plan may vest and be  exercised  from  time to time over the
period  stated in each  option  in such  amounts  and at such  times as shall be
prescribed  by the  Committee,  provided that options shall not be exercised for
fractional shares. Unless otherwise determined by the Committee, if the optionee
does not  exercise an option in any one year with  respect to the full number of
Shares to which the  optionee is entitled in that year,  the  optionee's  rights
shall be cumulative and the optionee may purchase those Shares in any subsequent
year during the term of the option.

     (e)  Restrictions  on Transfer.  Each option  granted under the Plan by its
terms  shall  be  nonassignable  and  nontransferable  by the  optionee,  either
voluntarily or by operation of law, except by will or by the laws of descent and
distribution  of the state or country of the optionee's  domicile at the time of
death,  and each option by its terms shall be exercisable  during the optionee's
lifetime only by the optionee;  provided, however, that, with the consent of the
Committee,  which consent may be withheld in its sole  discretion or conditioned
on such  requirements  as the Committee  shall deem  appropriate,  an officer or
director of the Company who is subject to Section  16(b) of the Exchange Act may
assign or transfer  without  consideration  all or any portion of a Nonstatutory
Stock Option  granted under the Plan to such  officer's or directors  spouse (or
former spouse) pursuant to a qualified  domestic  relations order. The holder of
any  Nonstatutory  Stock  Option  that has  been  transferred  pursuant  to this
paragraph 6(e) may be subject to treatment  under tax and  securities  laws with
respect to the transferred  option which differs from the treatment to which the
applicable  officer or director  was subject with respect to the option prior to
the transfer.

     (f) Termination of Employment or Service.

          (i) In the event the  employment  or  service of the  optionee  by the
     Company or a parent or subsidiary corporation of the Company terminates for
     any reason other than because of death or physical  disability,  the option
     may be exercised at any time prior to the expiration  date of the option or
     the  expiration  of three  months (one year in the case of officers and two
     years  in 

<PAGE>

     the case of directors)after the date of such termination,  whichever is the
     shorter period,  but only if and to the extent the optionee was entitled to
     exercise the option at the date of such termination.

          (ii) In the event of the  termination of the optionee's  employment or
     service  with the  Company  or a parent or  subsidiary  corporation  of the
     Company  because  the  optionee  becomes  disabled  (within  the meaning of
     Section  22(e)(3)  of the Code),  the option may be  exercised  at any time
     prior to the  expiration  date of the option or the  expiration of one year
     after the date of such  termination,  whichever is the shorter period,  but
     only if and to the extent the  optionee was entitled to exercise the option
     at the date of such termination.

          (iii) In the event of the death of an  optionee  while  employed by or
     providing  service to the Company or a parent or subsidiary  corporation of
     the  Company,  the  option  may be  exercised  at  any  time  prior  to the
     expiration  date of the option or the expiration of one year after the date
     of such  death,  whichever  is the shorter  period,  but only if and to the
     extent the  optionee  was  entitled to  exercise  the option on the date of
     death,  and only by the person or persons  to whom such  optionee's  rights
     under  the  option  shall  pass by the  optionee's  will or by the  laws of
     descent and distribution of the state or country of domicile at the time of
     death.

          (iv) The  Committee,  at the time or grant or at any time  thereafter,
     may extend the  three-month and one-year  expiration  periods any length of
     time not later than the  original  expiration  date of the option,  and may
     increase  the  portion of an option  that is  exercisable,  subject to such
     terms and conditions as the Committee may determine.

          (v) To the extent that the option of any  deceased  optionee or of any
     optionee whose employment or service terminates is not exercised within the
     applicable  period,  all further rights to purchase Shares pursuant to such
     option shall cease and terminate.

     (g) Purchase of Shares. Unless the Committee determines  otherwise,  Shares
may be acquired pursuant to an option only upon receipt by the Company of notice
in writing from the optionee of the optionee's intention to exercise, specifying
the number of Shares as to which the optionee desires to exercise the option and
the date on which the  optionee  desires to complete  the  transaction,  and, if
required  to  comply  with the  Securities  Act of 1933,  as  amended,  or state
securities  laws,  the  notice  shall  include a  representation  that it is the
optionee's present intention to acquire the Shares for investment and not with a
view to distribution.  The  certificates  representing the Shares shall bear any
legends required by the Committee. Unless the Committee determines otherwise, on
or before the date specified for  completion of the purchase of Shares  pursuant
to an option, the optionee must have paid the Company the full purchase price of
such Shares in cash (including, with the consent of the Committee, cash that may
be the  proceeds  

<PAGE>

of a loan from the Company), or, with the consent of the Committee,  in whole or
in part,  in Shares  valued at fair  market  value,  as  determined  pursuant to
paragraph 6(b)(iv). Unless the Committee determines otherwise, all payments made
to the Company in  connection  with the  exercise of an option must be made by a
certified or cashier's  bank check or by the transfer of  immediately  available
federal  funds.  No Shares shall be issued until full payment  therefor has been
made. With the consent of the Committee,  an optionee may request the Company to
apply  automatically the Shares to be received upon the exercise of a portion of
a stock  option (even  though  stock  certificates  have not yet been issued) to
satisfy the purchase price for additional  portions of the option. Each optionee
who has exercised an option shall  immediately  upon  notification of the amount
due,  if any,  pay to the  Company in cash  amounts  necessary  to  satisfy  any
applicable federal, state and local tax withholding requirements.  If additional
withholding is or becomes  required beyond any amount  deposited before delivery
of the  certificates,  the  optionee  shall pay such  amount to the  Company  on
demand.  If the optionee  fails to pay the amount  demanded,  the Company or any
parent or  subsidiary  corporation  of the Company may withhold that amount from
other amounts payable to the optionee by the Company or the parent or subsidiary
corporation,  including  salary,  subject to applicable law. With the consent of
the  Committee,  an optionee  may  deliver  Shares to the Company to satisfy the
withholding obligation.

7.  Stock  Bonuses.  The  Committee  may  award  Shares  under the Plan as stock
bonuses.  Shares  awarded  as a stock  bonus  shall be  subject  to such  terms,
conditions,  and  restrictions  as shall be determined by the Committee,  all of
which shall be evidenced in a writing signed by the recipient prior to receiving
the bonus  Shares.  The  Committee  may not  require  the  recipient  to pay any
monetary  consideration  other than amounts necessary to satisfy tax withholding
requirements.  The  certificates  representing the Shares awarded shall bear any
legends  required by the  Committee.  The Company may require any recipient of a
stock  bonus to pay to the  Company in cash upon  demand  amounts  necessary  to
satisfy any applicable federal, state or local tax withholding requirements.  If
the  recipient  fails to pay the amount  demanded,  the Company or any parent or
subsidiary  corporation  of the  Company  may  withhold  that  amount from other
amounts  payable to the  recipient  by the  Company or the parent or  subsidiary
corporation,  including  salary,  subject to applicable law. With the consent of
the  Committee,  a recipient  may  deliver  Shares to the Company to satisfy the
withholding obligation.

8.  Stock  Sales.  The  Committee  may  issue  Shares  under  the  Plan for such
consideration  (including  promissory  notes and  services) as determined by the
Committee,  provided  that in no event shall the  consideration  be less than 75
percent  of the  fair  market  value  of the  Shares  at the  time of  issuance,
determined pursuant to paragraph 6(b)(iv).  Shares issued under this paragraph 8
shall be subject to the terms,  conditions  and  restrictions  determined by the
Committee. The restrictions may include restrictions concerning transferability,
repurchase  by the Company and  forfeiture of the Shares  issued,  together with
such other restrictions as may be determined by the Committee.  The certificates
representing  the Shares shall bear any legends  required by the Committee.  The
Company may require any purchaser of stock issued under this  paragraph 8 to pay
to the Company in cash upon demand  amounts  necessary to satisfy any applicable
federal, state or local tax withholding requirements.  If the purchaser fails to
pay the amount demanded,  the Company or any parent or subsidiary corporation of
the Company may

<PAGE>

withhold that amount from other amounts  payable to the purchaser by the Company
or any parent or subsidiary corporation, including salary, subject to applicable
law. With the consent of the  Committee,  a purchaser may deliver  Shares to the
Company to satisfy the withholding obligation.

9. Stock Appreciation Rights.

     (a) Grant. Stock  appreciation  rights may be granted under the Plan by the
Committee,  subject  to such  rules,  terms,  and  conditions  as the  Committee
prescribes.

     (b) Exercise.

          (i) A stock  appreciation  right shall be exercisable only at the time
     or times  established by the Committee.  If a stock  appreciation  right is
     granted in connection with an option, the stock appreciation right shall be
     exercisable  only to the extent and on the same conditions that the related
     option could be exercised. Upon exercise of a stock appreciation right, any
     option or portion  thereof to which the stock  appreciation  right  relates
     terminates.  If a stock appreciation right is granted in connection with an
     option,  upon  exercise  of the  option,  the stock  appreciation  right or
     portion thereof to which the option relates terminates.

          (ii) The Committee may withdraw any stock  appreciation  right granted
     under the Plan at any time and may impose any conditions  upon the exercise
     of a stock  appreciation  right or adopt rules and regulations from time to
     time  affecting the rights of holders of stock  appreciation  rights.  Such
     rules and regulations  may govern the right to exercise stock  appreciation
     rights granted before  adoption or amendment of such rules and  regulations
     as well as stock appreciation rights granted thereafter.

          (iii) Each stock  appreciation  right shall  entitle the holder,  upon
     exercise,  to receive from the Company in exchange therefor an amount equal
     in value to the excess of the fair market  value on the date of exercise of
     one Share over its fair market  value on the date of grant (or, in the case
     of a stock  appreciation  right granted in connection  with an option,  the
     option  price per Share  under the  option to which the stock  appreciation
     right  relates),  multiplied  by the number of Shares  covered by the stock
     appreciation right or the option, or portion thereof,  that is surrendered.
     No stock  appreciation right shall be exercisable at a time that the amount
     determined under this subparagraph is negative. Payment by the Company upon
     exercise of a stock appreciation right may be made in Shares valued at fair
     market  value,  in cash,  or partly in Shares  and  partly in cash,  all as
     determined by the Committee.

          (iv) For  purposes of this  paragraph  9, the fair market value of the
     Shares shall be determined pursuant to paragraph  6(b)(iv),  on the trading
     day preceding the date the 

<PAGE>

     stock appreciation right is exercised.

          (v) No  fractional  Shares  shall be issued  upon  exercise of a stock
     appreciation right. In lieu thereof, cash may be paid in an amount equal to
     the value of the fraction or, if the Committee shall determine,  the number
     of Shares may be rounded downward to the next whole Share.

          (vi) Each  participant  who has exercised a stock  appreciation  right
     shall,  upon  notification  of the amount  due,  pay to the Company in cash
     amounts  necessary to satisfy any  applicable  federal,  state or local tax
     withholding  requirements.  If the  participant  fails  to pay  the  amount
     demanded,  the  Company  or any  parent or  subsidiary  corporation  of the
     Company  may  withhold  that  amount  from  other  amounts  payable  to the
     participant  by  the  Company  or any  parent  or  subsidiary  corporation,
     including  salary,  subject  to  applicable  law.  With the  consent of the
     Committee, a participant may satisfy this obligation,  in whole or in part,
     by having  the  Company  withhold  from any  Shares  to be issued  upon the
     exercise  that number of Shares that would satisfy the  withholding  amount
     due or by  delivering  Shares to the  Company  to satisfy  the  withholding
     amount.

          (vii) Upon the exercise of a stock  appreciation right for Shares, the
     number of Shares  reserved for issuance  under the Plan shall be reduced by
     the number of Shares  issued.  Cash payments of stock  appreciation  rights
     shall not reduce the number of Shares reserved for issuance under the Plan.

10. Option Grants to Non-Employee Directors.

     (a)  Automatic   Grants.   Immediately  after  the  close  of  each  annual
shareholder meeting (commencing with the 1993 annual meeting),  each person then
serving as a Non-Employee Director,  including any such person who is elected at
such meeting,  shall  automatically  be granted a  Nonstatutory  Stock Option to
purchase  17,500  Shares.  For  purposes  of  this  paragraph,  a  "Non-Employee
Director"  is a director of the Company who is not an employee of the Company or
of any parent or subsidiary corporation of the Company on the date the option is
granted.

     (b) Terms of Options.  The exercise  price for options  granted  under this
paragraph  10 shall be the fair market value of the Shares on the date of grant,
determined  pursuant  to  paragraph  6(b)(iv).  Each such  option  shall have an
eight-year term from the date of grant, unless earlier terminated as provided in
paragraph  6(f),  and shall vest and become  exercisable  with  respect to 8,750
shares six  months  after the date of grant,  with the  remaining  8,750  shares
vesting and becoming exercisable on the first anniversary of the date of grant.

11. Changes in Capital  Structure.  If the outstanding shares of Common Stock of
the Company are  hereafter  increased  or decreased or changed into or exchanged
for a different  number or kind of shares or other  securities of the Company or
of  another  corporation  by reason of any  recapitalization,  

<PAGE>

reclassification,  stock  split,  combination  of shares or dividend  payable in
shares,  the Committee shall make appropriate  adjustments (i) in the number and
kind of shares  available for awards under the Plan;  and (ii) in the number and
kind of shares as to which outstanding options and stock appreciation rights, or
portions  thereof  then   unexercised,   shall  be  exercisable,   so  that  the
participant's  proportionate  interest  before and after the  occurrence  of the
event is  maintained,  provided  that this  paragraph  11 shall  not apply  with
respect to  transactions  referred to in paragraph  12. The  Committee  may also
require that any securities  issued in respect of or exchanged for Shares issued
hereunder that are subject to restrictions  be subject to similar  restrictions.
Notwithstanding the foregoing,  the Committee shall have no obligation to effect
any adjustment that would or might result in the issuance of fractional  shares,
and any  fractional  shares  resulting from any adjustment may be disregarded or
provided for in any manner determined by the Committee. Any such adjustment made
by the Committee shall be conclusive.

12. Effect of Reorganization or Liquidation.

     (a)  Cash,  Stock or Other  Property  for  Stock.  Except  as  provided  in
paragraph 12(b), upon a merger, consolidation,  reorganization, plan of exchange
or liquidation  involving the Company,  as a result of which the shareholders of
the  Company  receive  cash,  stock  or other  property  in  exchange  for or in
connection  with their Common Stock (any such  transaction  to be referred to in
this paragraph 12 as an "Accelerating  Event"), any option or stock appreciation
right granted  hereunder shall terminate,  but the optionee shall have the right
during a 30-day  period  immediately  prior  to any such  Accelerating  Event to
exercise  his or her option or stock  appreciation  right,  in whole or in part,
without any limitation with respect to vesting or exercisability

     (b) Stock for Stock.  If the  shareholders  of the Company  receive capital
stock of another  corporation  ("Exchange  Stock") in exchange  for their Common
Stock in any transaction involving a merger, consolidation,  reorganization,  or
plan of exchange,  all options granted hereunder shall be converted into options
to purchase shares of Exchange Stock and all stock  appreciation  rights granted
hereunder  shall be converted  into stock  appreciation  rights  measured by the
Exchange Stock,  unless the Committee,  in its sole discretion,  determines that
any or all such options or stock appreciation rights granted hereunder shall not
be converted,  but instead shall  terminate in accordance with the provisions of
paragraph  12(a).   The  amount  and  price  of  converted   options  and  stock
appreciation rights shall be determined by adjusting the amount and price of the
options or stock appreciation  rights granted hereunder to take into account the
relative values of the Exchange Stock and the Common Stock in the transaction.

     (c) The rights set forth in this paragraph 12 shall be transferable only to
the extent the related option or stock appreciation right is transferable.

13. Corporate Mergers, Acquisitions,  Etc. The Committee may also grant options,
grant stock  appreciation  rights,  award stock bonuses and sell stock under the
Plan having terms,  conditions and provisions  that vary from those specified in
the Plan;  provided that any such awards are granted in 

<PAGE>

substitution  for, or in connection  with the assumption of,  existing  options,
stock  appreciation  rights,  stock bonuses and stock sold or awarded by another
corporation  and assumed or  otherwise  agreed to be provided for by the Company
pursuant  to or  by  reason  of a  transaction  involving  a  corporate  merger,
consolidation,  acquisition of property or stock, separation,  reorganization or
liquidation  to which the Company or a parent or subsidiary  corporation  of the
Company is a party.

14. Amendment of Plan. The Board may at any time, and from time to time,  modify
or amend the Plan in such respects as it shall deem advisable because of changes
in the law  while  the Plan is in  effect  or for any  other  reason.  Except as
provided in paragraphs  6(b)(v),  11, 12 and 13, however,  no change in an award
already  granted shall be made without the written consent of the holder of such
award.

15. Approvals.  The obligations of the Company under the Plan are subject to the
approval of state and federal  authorities or agencies with  jurisdiction in the
matter.  The Company shall not be obligated to issue or deliver Shares under the
Plan if such  issuance or delivery  would  violate  applicable  state or federal
securities  laws, or if compliance  with such laws would,  in the opinion of the
Company,  be unduly  burdensome or require the disclosure of  information  which
would not be in the Company's best interests.

16. Employment and Service Rights.  Nothing in the Plan or any award pursuant to
the Plan shall (i) confer upon any  employee  any right to be  continued  in the
employment of the Company or any parent or subsidiary corporation of the Company
or shall  interfere  in any way with the right of the  Company  or any parent or
subsidiary  corporation  of the  Company by whom such  employee  is  employed to
terminate  such  employee's  employment  at any time,  for any  reason,  with or
without  cause,  or to increase  or decrease  such  employee's  compensation  or
benefits; or (ii) confer upon any person engaged by the Company or any parent or
subsidiary  corporation  of the  Company any right to be retained or employed by
the  Company  or the parent or  subsidiary  or to the  continuation,  extension,
renewal, or modification of any compensation,  contract,  or arrangement with or
by the Company or the parent or subsidiary.

17.  Rights as a  Shareholder.  The  recipient of any award under the Plan shall
have no rights as a  shareholder  with  respect to any Shares  until the date of
issue to the  recipient  of a stock  certificate  for  such  Shares.  Except  as
otherwise  expressly  provided  in the  Plan,  no  adjustment  shall be made for
dividends  or other  rights for which the record  date is prior to the date such
stock certificate is issued.
