ITEM 1. BUSINESS.

Introduction

  OXIS International, Inc., ("OXIS" or the "Company"), a Delaware corporation,
is engaged in the discovery, development and commercialization of therapeutic
and diagnostic products to diagnose, treat and prevent diseases of oxidative
stress. Oxidative stress occurs when the concentration of free radicals and
reactive oxygen species ("ROS"), highly reactive molecules produced during
oxidative processes, exceed the body's antioxidant defense mechanisms.

  In February 1998, the Company's Board of Directors approved the
restructuring of the Company into two wholly owned subsidiaries, OXIS Health
Products, Inc. and OXIS Therapeutics, Inc. The restructuring was completed in
April 1998. Since that time the Company's commercial health products business,
which manufactures and sells medical instruments and markets research and
commercial diagnostic assays and fine chemicals to research and clinical
laboratories and other customers, has been carried out by OXIS Health
Products, Inc. The Company's drug discovery business, which is focused on new
drugs to treat diseases associated with tissue damage from free radicals and
ROS, is being carried out by OXIS Therapeutics, Inc. For financial information
about these two operating segments, see Note 8 to the consolidated financial
statements.

  OXIS is currently undertaking a restructuring and reorganization under which
the non-therapeutic assets of the Company, including substantially all of the
assets of OXIS Health Products, Inc., are to be divested or spun off and the
Company will be refocused in the area of ethical pharmaceutical development.
As a part of this reorganization and restructuring, the senior management team
of OXIS is being expanded and reconfigured including the appointment of Paul
C. Sharpe, M.D. as Chief Executive Officer effective February 15, 2000 and the
appointment of Timothy C. Rodell, M.D., who has been a senior executive with
the Company since 1996, as Chief Technology Officer. This restructuring and
reorganization is in its early stages and the Company has not yet determined
whether to sell the stock or assets of OXIS Health Products, Inc. or to spin
that company off to the OXIS shareholders. The Company's therapeutic business
will continue to be founded on the development of the three classes of small
molecular weight antioxidant molecules currently under development but is
expected to be expanded by merger and/or acquisition and in-licensing to
include other compounds in late preclinical and early clinical development. It
is expected that technology added to the portfolio will include an expansion
of the Company's franchise in antioxidant molecules but will also include
molecules from other classes, particularly in the areas of central nervous
system, gastrointestinal and cardiopulmonary disease.

                                       1
<PAGE>

  The Company's lead therapeutic drug candidate, BXT-51072, has recently
completed a Phase IIA clinical trial in inflammatory bowel disease ("IBD"). A
larger Phase IIB trial is in the planning stages and is expected to be
initiated later this year. Two other therapeutic programs are in the
preclinical stage of development.

  The Company derives current business revenues primarily from sales of
medical instruments, diagnostic assays and two fine chemicals, ergothioneine
and bovine superoxide dismutase ("bSOD"). The Company's diagnostic products
include seventeen assays to measure oxidative stress and fourteen commercial
therapeutic drug monitoring ("TDM") assays based on fluorescence polarization
immunoassay technology ("FPIA") that are manufactured on a contract basis for
the company that purchased that technology in 1999.

  The assays for markers of oxidative stress are sold through international
distribution and catalog sales to basic researchers and clinicians working in
oxidative stress research. The Company's oxidative stress assays run on a
variety of commercially available instruments. Certain of these assays run on
the OxyScan instrument developed and manufactured by the Company.

  The Company has invested significant resources to build an early and
substantial patent position on both its antioxidant therapeutic technologies
and selected oxidative stress assays.

  The Company's corporate offices and assay manufacturing facilities are
located in a 15,000 sq. ft. facility at 6040 N. Cutter Circle, Suite 317,
Portland, OR 97217. Facilities for developing and manufacturing medical
instruments are located at 55 Steam Whistle Drive, Ivyland, PA 18974.

Acquisitions/Facility Closure

  On December 31, 1997, the Company acquired all of the issued and outstanding
capital stock of Innovative Medical Systems Corp. ("IMS"), a Pennsylvania
corporation, in exchange for 200,000 shares of the Company's common stock
issued immediately and additional common shares to be issued. The name of IMS
was subsequently changed to OXIS Instruments, Inc. OXIS Instruments, Inc.
develops, manufactures, markets and sells medical instruments, including a
laboratory analyzer that has been modified to automate certain of the
Company's assays to measure markers of oxidative stress.

  In the first quarter of 1999 the Company announced the planned closure of
its research laboratory in France. The French facility was closed in the
second quarter of 1999.

  In the course of its operations the Company may determine to seek additional
new business opportunities through additional mergers or acquisitions.

Research and Development

  The Company's research and development programs with respect to its
therapeutics business are carried out by OXIS Therapeutics, Inc. OXIS'
strategy is to develop potent, synthetic, small molecular weight (and
therefore orally bioavailable) antioxidants which can penetrate cells in high
concentrations to protect against direct ROS damage as well as reduce the
activation of transcription factors such as NFkB and therefore reduce
inflammation, apoptosis and other major and fundamental disease processes. If
vitamins can be viewed as the first generation of antioxidants and large
enzymes, such as SOD can be viewed as the second generation antioxidants, OXIS
believes it is now developing the third generation of antioxidants.

OXIS Technology

  Because of the wide range of diseases and organ systems affected by
oxidative stress and its consequences, no single compound or family of
compounds is likely to be appropriate for all indications. For this reason,
OXIS is developing three families of molecules which are targeted to different
disease indications.

  The Company is targeting acute and subacute inflammatory diseases with a
family of small molecular weight mimics of the enzyme glutathione peroxidase
("GPx"). These molecules have been demonstrated to block direct oxidative
damage in vitro, to block NFkB activation at low nanomolar concentrations and
to block

                                       2
<PAGE>

the production of numerous cytokines and other molecules which are under the
control of NFkB. These molecules have also been shown in animal models to
block endotoxic shock, restenosis and inflammatory bowel disease.

  The second series of molecules is designed to mimic the salutary activity of
vitamin E while addressing its limitations as a pharmaceutical. Vitamin E is
the predominant natural lipid soluble antioxidant in animals and, as such, has
a primary role in the protection of cell membranes from damage from ROS. This
role is critical in cardiovascular and central nervous system disease. The
limitations of vitamin E as an antioxidant are its potency, which is very low,
and its kinetics of membrane incorporation. In-vitro models have shown the
OXIS Lipid Soluble Antioxidants (LSAs) are twenty to forty fold more potent
than vitamin E as antioxidants and are incorporated into membranes a great
deal more quickly. These molecules are currently targeted for development in
the area of cardiovascular and neurodegenerative disease.

  The third series of molecules is designed around a natural antioxidant known
as l-ergothioneine. L-ergothioneine itself is a sulfur-containing antioxidant,
related to glutathione, which is a natural product and which is contained in
tissues in the body subjected to significant oxidative stress such as the lens
of the eye, the liver and red blood cells. Unlike glutathione, l-ergothioneine
is stable in aqueous solutions and is well absorbed orally. Humans do not
synthesize l-ergothioneine and therefore require it in their diet. It has been
demonstrated to be depleted in the lens of the eye in patients with cataracts,
and the Company is currently investigating its levels in a number of other
disease states including AIDS. OXIS holds a patent for what it believes to be
the only commercially feasible synthetic process for pure l-ergothioneine. In
addition, Company scientists have synthesized a series of proprietary analogs
of l-ergothioneine which are more potent and which can be developed in areas
where a proprietary position on natural l-ergothioneine is not available.

Selection of Clinical Targets

  OXIS believes that the control or elimination of oxidative stress represents
an important but largely untapped area for drug development that holds
potential for significant clinical benefit. A large number of complex diseases
are thought to be directly caused by damage from free radicals and other ROS,
and many others have a component attributable to oxidative stress. Many of
these are diseases for which there is currently no acceptable therapy, or the
therapy is inadequate.

  OXIS has selected inflammatory bowel disease, including ulcerative colitis
and Crohn's disease, cardiovascular disease and the neurodegenerative diseases
as its primary targets.

  Several factors were considered in selecting these major disease areas and
indications including: scientific rationale; unmet medical need; market size;
potential partners; competing therapeutic strategies; and cost to develop a
marketable outlicensing package. The markets initially chosen in terms of
target indications also represent an extension of OXIS' strategy to reduce the
time and costs required for the development of antioxidant therapeutics. In
each of the pharmaceutical project focus areas, potential alliance partners
will be identified. As of the date of this report, the Company has not entered
into any agreements with such alliance partners.

Markets

  The prevalence of ulcerative colitis is estimated to be 0.1% in developed
countries. This yields an approximate population of 250,000 patients in the
U.S. and 300,000 in western Europe. Crohn's disease, which the Company
believes will also be amenable to therapy with BXT-51072, has approximately
the same prevalence, so the combined market for the U.S. and Europe is between
1-1.2 million patients. Using a conservative pricing estimate of $1000 per
patient per year, this yields a market size of approximately one billion
dollars per year.

  Other indications for BXT-51072 or a follow-on compound, such as restenosis,
inflammatory arthritis, stroke and reperfusion injury would add significantly
to the market potential.


                                       3
<PAGE>

  The LSAs will be initially targeted for neurodegenerative and cardiovascular
diseases. These markets represent multi-billion dollar opportunities, but
given the early stage of development of these molecules, specific market
estimates are not yet meaningful.

Clinical results to date with BXT-51072

  To date, BXT-51072 has been administered to over 50 patients and volunteers
in one Phase I study and a Phase IIA study in patients with ulcerative
colitis. No drug related serious adverse events have been seen to date and the
drug has been shown to be rapidly absorbed by the oral route.

  In the Phase IIA trial, 20 patients with mild to moderate ulcerative colitis
who had failed first line therapy (5-ASA drugs) received one of two dosage
regimens of BXT-51072 for 28 days. The primary end point was the Mayo Colitis
Activity Index ("CAI"), a well accepted composite clinical disease activity
score. While the data are still being analyzed, several findings have already
emerged:

  . There is a statistically significant improvement in CAI from Day 1 to Day
    28 in both dose groups;

  . Several patients had rapid, dramatic improvements in their clinical
    picture;

  . There is a suggestion (not statistically significant) of a dose response.

  In addition, biochemical tests performed on colon biopsy specimens showed a
reduction in markers of oxidative stress with treatment.

  The Company is currently planning a larger Phase IIB trial to confirm these
initial encouraging findings.

Other Programs

  In addition to its research and development programs in synthetic
antioxidants, OXIS also has conducted research programs in the development of
oxidative stress assays, bovine superoxide dismutase and poly-ethylene glycol
technology. The status of these programs are as follows:

    Oxidative Stress Assays. The Company has developed ten research assay
  kits for markers of oxidative stress that are designed to ultimately
  facilitate diagnosis and optimize therapy of free radical-associated
  diseases. These assays are being sold by OXIS Health Products, Inc.
  primarily to basic researchers and clinicians working in oxidative stress
  research. These assays also provide developmental synergy for the
  pharmaceutical research and development programs by facilitating the
  assessment of oxidative stress in laboratory studies and in patients. These
  assays are part of the OXIS Health Products, Inc. assets to be spun out or
  divested by the Company.

    Bovine Superoxide Dismutase (bSOD). The Company also has extensive
  experience in developing, manufacturing and marketing bovine superoxide
  dismutase ("bSOD"). Bovine superoxide dismutase has been previously studied
  in numerous clinical trials by OXIS and other companies. OXIS is not
  currently pursuing an active research program in bSOD, but through its
  subsidiary, OXIS Health Products, Inc., supplies bulk bSOD for human use
  and sells an injectable dosage form of the drug for veterinary applications
  under the registered trademark Palosein(R). The bSOD technology is also
  part of the OXIS Health Products, Inc. assets subject to the spin-off or
  divestiture.

    Poly-Ethylene Glycol Technology (PEG). The Company is not currently
  pursuing an active research program in PEG technology. During 1999 the
  Company entered into a licensing arrangement giving Enzon, Inc. the right
  to its PEG technologies.

  Overall, the Company has an extensive portfolio of patents that cover its
synthetic antioxidant therapeutic molecules, assays for markers of oxidative
stress and fine chemicals. The Company currently holds seventeen U.S. patents
and five French patents on other compounds expiring between 2006 and 2017.

  The Company's overall research and development strategy has been to discover
and advance its therapeutic molecules through early stage clinical trials to
demonstrate efficacy in the target disease populations. The

                                       4
<PAGE>

Company expects to seek strategic pharmaceutical partners for later stage
clinical development and commercialization of its therapeutics, but, to date,
has not entered into any such partnership and no assurances can be given that
it will enter into any such partnership. Without such partnerships, it is
unlikely that the Company will be able to complete the development of its
therapeutics.

  Much of the Company's success depends on its potential products which are in
research and development and from which no material revenues have yet been
generated. The Company must successfully partner, develop, obtain regulatory
approval for and market or sell its potential therapeutic products to achieve
profitable operations. No assurances can be given that the Company's product
development efforts will be successfully completed, that required regulatory
approvals will be obtained, or that any such products, if developed and
introduced will be successfully marketed. Furthermore, no assurances can be
given that the Company will be able to raise the working capital necessary to
continue to advance its research and development programs. Competition in the
pharmaceutical industry is intense, and no assurances can be given that OXIS'
competitors will not develop technologies and products that are more effective
than those being developed by OXIS.

  Research and development expenses were $2,401,000, $4,374,000 and $4,319,000
for the years ended December 31, 1999, 1998 and 1997, respectively.

Commercial Health Products

 Diagnostic Products

  Revenues from sales of the Company's diagnostic products comprised 38% of
its revenues in 1999, 44% of its revenues in 1998 and 49% of its revenues in
1997.

  Oxidative Stress Research Products. The Company offers more than 140
research products for sale that include:

              Assays for markers of oxidative stress
              Spin traps
              Antibodies
              Proteins
              Specialty chemicals
              Controls

  The primary technology foundation for the research product line are eleven
assay test kits which measure key markers in free radical biochemistry
(markers of oxidative stress). Specifically, these assays measure levels of
antioxidant protection, oxidative alterations, and pro-oxidant activation of
specific white blood cells.

  These assay kits utilize either chemical (colorimetric) or immunoenzymatic
(EIA) reactions that can be read using laboratory spectrophotometers and
microplate readers, respectively. The Company believes its assays offer
advantages over conventional laboratory methods, including ease of use, speed,
specificity and accuracy.

  The assays for markers of oxidative stress are currently being sold to
researchers in Europe, Japan and the United States, primarily through
distributors. The Company estimates that there are more than 3,500 scientists
and clinicians who are working directly in research on free radical
biochemistry, and who are potential customers for these research assays. Eight
of the Company's research assays are manufactured at the facility in Portland,
Oregon. The others are manufactured pursuant to private label agreements.

  The Company's assays for markers of oxidative stress are generally protected
by trade secrets, and to a more limited extent, patents. Four French patents
and two U.S. patents have been issued with respect to these assays. The
oxidative stress assays are sold under the registered trademark
"Bioxytech(R)".

  Several companies other than OXIS have developed assays for markers of
oxidative stress and offer assays that compete directly with the Company's
assays for superoxide dismutase, cellular glutathione peroxidase, reduced
glutathione, lipid peroxidation and glutathione reductase. No assurances can
be given that the Company will compete successfully with such competitive
assays.

                                       5
<PAGE>

  All of the research products are manufactured in batches in anticipation of
customer orders. Orders are generally filled within a few days; therefore, the
Company does not have any significant backlog of orders for its research
products. The Company believes that adequate supplies of raw materials are
either currently on hand, available from commercial suppliers or available
through development on a custom basis by commercial contractors, as needed.

  Therapeutic Drug Monitoring (TDM) Assays. In its Portland, Oregon facility
the Company manufactures fourteen TDM assays which are based on FPIA
(fluorescent polarization immunoassay) technology.

  The TDM products were sold through a combination of direct customer sales
and distributors in the United States, and through a network of distributors
outside the United States, principally in Europe. Effective June 28, 1999, the
Company sold the intellectual property, contract rights and finished goods
inventory relating to its therapeutic drug monitoring assays. Proceeds from
the sale consisted of $500,000 cash, a non-interest bearing note (collected in
1999) and a warrant granting the Company the right to acquire an equity
interest in the purchaser of the assets.

  The Company recognized $911,000 as compensation for the intellectual
property and contract rights. This amount has been included in revenues for
1999. The Company has entered into an agreement with the purchaser of the
therapeutic drug monitoring assays pursuant to which the Company will continue
to manufacture the products and perform certain other services for the
purchaser through the third quarter of 2000. The sale of intellectual property
and contract rights together with product sales to the purchaser amounted to
21% of the Company's revenues in 1999.

  Wellness Services.  The Company's Wellness Services program provides
products and services to help consumers make informed decisions regarding
their current and future health goals. Testing to measure oxidative damage,
antioxidants, nutritional supplements and other key biomarkers is provided by
the Company's wellness testing laboratory. The Company participates or sets up
health fairs through its WellnessFairs program in collaboration with
nutritional product stores, health centers and employers.

  The goal of the Wellness Services program is to provide answers that will
enable consumers to have better control of their health as they age, allowing
them to have a productive and healthy life. The Company participates in this
market by offering WellnessFairs, wellness testing, health risk assessment
questionnaires, e-commerce (health content and products) and wellness research
products.

  OxyScan Instrument System. The Company has developed the OxyScan System
which includes both reagents and instrumentation to measure oxidative and
nutritional status. The Company believes the OxyScan System to be the first
dedicated system on the market for measurement of oxidative and nutritional
status. Several OxyScan instruments have been placed in research centers.

  The Company believes that its combination of reagent technology and
instrumentation offers this market for the first time a dedicated system to
facilitate testing without the extra steps involved with other manual
methodologies. The OxyScan System will provide faster assay throughput and
better turnaround time for oxidative damage and nutritional supplement assays
than has previously been available. The Company believes that it will have a
competitive advantage by offering a dedicated system for oxidative and
nutritional status testing which offers the following advantages (i) reduced
labor costs, (ii) reduced reagent costs, (iii) improved turnaround time and
(iv) testing flexibility. The Company only recently commenced marketing the
OxyScan, and no assurances can be given that the OxyScan will become a
commercially successful product.

 Medical Instruments

  With the acquisition of OXIS Instruments, Inc., effective December 31, 1997,
the Company acquired staff, facilities and equipment to develop and
manufacture medical instruments. Revenues from sales of medical instruments
comprised approximately 18% of the Company's total revenues in 1999 and 48% in
1998. Instruments currently being manufactured include tissue processors,
automated stainers and the OxyScan

                                       6
<PAGE>

instrument. OXIS Instruments, Inc., generally manufactures product to fill
specific orders, and had a backlog of orders of approximately $500,000 at
December 31, 1999 and $1,100,000 at December 31, 1998. While the Company
believes such orders to be firm, orders from customers are generally
cancelable. The Company believes that adequate supplies of raw materials are
either currently on hand or available from commercial suppliers, as needed.

 Therapeutic Products

  Revenues from sales of bulk bSOD and sales of Palosein, the Company's
veterinary bSOD product, comprised approximately 19% of the Company's total
revenues in 1999, 4% in 1998 and 42% in 1997.

  Bovine SOD (bSOD) Products. Commercial-scale manufacture and quality control
of bulk bSOD, as well as subsequent quality control and processing of United
States Department of Agriculture-inspected edible beef liver into highly
purified bulk bSOD requires a complex, multi-step process. OXIS has
significant knowledge regarding the manufacture of bSOD that is protected
through trade secrets and proprietary know-how.

  The Company has an agreement with Diosynth B.V., a Dutch contract
manufacturer of pharmaceutical ingredients, to manufacture bulk bSOD and
supply it to OXIS under the terms of a license based on the Company's
processes. Diosynth B.V. is an affiliate of AKZO-Nobel N.V., a large, Dutch
multinational chemical and health care company. The Company believes that its
present source of bSOD is adequate for its near-term foreseeable needs.

  The Company's patents protecting the manufacture of bSOD have expired.
Expiration of the Company's patents may enable other companies to benefit from
research and development efforts of the Company, but such other companies
would not receive the benefits of the Company's unpatented trade secrets and
know-how or unpublished preclinical or clinical data. Such companies would
still be required to expend considerable resources to conduct preclinical and
clinical studies of their own pharmaceutical preparations of SOD to gain
regulatory approval.

  The Company sells bulk bSOD for human use outside the United States, but
does not market dosage forms of bSOD for human use. The Company does not
currently intend to seek approval for human use of bSOD in the United States
for any indication, and only intends to sell bulk bSOD to the extent that
there is a demand for it. Palosein(R) is OXIS' registered trademark for its
veterinary brand of bSOD. Although there are other sources of bSOD and other
laboratory and pilot-scale processes to produce bSOD, the Company believes
that it is the only company manufacturing bSOD on a commercial scale for
pharmaceutical uses.

  The Company's Spanish licensee, Tedec-Meiji Farma, S.A., which distributes
bSOD for human use in Spain, has been responsible for a significant portion of
the Company's revenues in recent years. Sales of bSOD to Tedec-Meiji were 16%
of the Company's revenues in 1999 and 31% in 1997. No sales were made to
Tedec-Meiji during 1998. The Company does not have any orders for delivery of
bulk bSOD subsequent to 1999.

Risk Factors

 Need for Additional Financing

  The Company has incurred losses in each of the last five years. As of
December 31, 1999, the Company had an accumulated deficit of approximately
$49,750,000. The Company expects to incur operating losses for the foreseeable
future. In March 2000, the Company sold equity securities with net proceeds of
approximately $4,580,000. Even with this additional capital, the Company
currently does not have sufficient capital resources to complete the Company's
contemplated development programs and no assurances can be given that the
Company will be able to raise such capital on terms favorable to the Company
or at all. The unavailability of additional capital could cause the Company to
cease or curtail its operations and/or delay or prevent the development and
marketing of the Company's potential pharmaceutical products.


                                       7
<PAGE>

 Research and Development Stage Products

  Much of the Company's success depends on potential products which are in
research and development and no material revenues have been generated to date
from sales of these potential products. The preclinical work for one potential
new therapeutic product is completed, and the clinical development stage has
commenced. No assurance can be given that the Company's product development
efforts will be successfully completed, that required regulatory approvals
will be obtained, or that any such products, if developed and introduced, will
be successfully marketed. If the Company does not successfully introduce new
products, its revenues and results of operations will be materially adversely
affected.

 Future Profitability Uncertain

  The Company expects to incur operating losses for the foreseeable future.
The Company's research and development expenses are expected to increase as
the Company continues human clinical testing. These losses and expenses may
increase and fluctuate from quarter to quarter as the Company expands its
development activities. There can be no assurance that the Company will ever
achieve profitable operations. The report of the Company's independent
auditors on the Company's financial statements for the period ended December
31, 1999 includes an explanatory paragraph referring to the Company's ability
to continue as a going concern. The Company anticipates that it will expend
significant capital resources in product research and development and in human
clinical trials. Capital resources may also be used for the acquisition of
complementary businesses, products or technologies. The Company's future
capital requirements will depend on many factors including: continued
scientific progress in its research and development programs; the magnitude of
these programs; the success of preclinical and clinical trials; the costs
associated with the scale-up of manufacturing; the time and costs required for
regulatory approvals; the time and costs involved in filing, prosecuting,
enforcing and defending patent claims; technological competition and market
developments; the establishment of and changes in collaborative relationships;
and the cost of commercialization activities and arrangements.

  While the Company believes that its new products and technologies show
considerable promise, its ability to realize significant revenues therefrom is
dependent upon the Company's success in developing business alliances with
pharmaceutical and/or biotechnology companies to develop and market these
products. To date, the Company has not established such business alliances and
there can be no assurance that the Company's effort to develop such business
alliances will be successful.

 Company is in Highly Competitive Business

  The biopharmaceutical industry is highly competitive. Competition in most of
the Company's primary current and potential product areas from large
pharmaceutical companies, and other companies, universities and research
institutions is intense and expected to increase. Relative to the Company,
many of these entities have substantially greater capital resources, research
and development staffs, facilities and experience in conducting clinical
trials and obtaining regulatory approvals, as well as in manufacturing and
marketing pharmaceutical products. In addition, these and other entities may
have or may develop new technologies or use existing technologies that are, or
may in the future be, the basis for competitive products.

  Any potential products that the Company succeeds in developing and for which
it gains regulatory approval will have to compete for market acceptance and
market share. For certain of the Company's potential products, an important
factor in such competition may be the timing of market introduction of
competitive products. Accordingly, the relative speed with which the Company
can develop products, complete the clinical testing and regulatory approval
processes and supply commercial quantities of the product to the market are
expected to be important competitive factors. The Company expects that a
competitive edge will be based, among other things, on product efficacy,
safety, reliability, availability, timing and scope of regulatory approval and
product price. There can be no assurance that the Company's competitors will
not develop technologies and products that are more effective than those being
developed by the Company. In addition, certain of the Company's competitors
may achieve product commercialization or patent protection prior to OXIS.

 NASDAQ Listing

  The Company has failed to meet certain requirements for continued listing on
the NASDAQ National Market. As further discussed in Item 5, to maintain such
listing, on or before April 14, 2000, the Company must make a public filing
evidencing a minimum of $8,000,000 in net tangible assets. The filing is to
contain a February 29, 2000 balance sheet with pro forma adjustments for any
significant events or transactions occurring on or before the filing date.

  No assurances can be given that the Company will be able to meet the
$8,000,000 requirement or that the common stock will remain listed on the
NASDAQ National Market. If the Company's common stock ceases to be listed on
the NASDAQ National Market, such failure to be listed could have a material
adverse effect on the transferability of the common stock, and may have a
material adverse effect on the value of the common stock as well.

Employees

  As of December 31, 1999, the Company had 52 employees, all in the United
States. None of the Company's employees are subject to a collective bargaining
agreement. The Company has never experienced a work interruption.

Foreign Operations and Export Sales

  For information regarding the Company's foreign operations and export sales,
see Note 8 to the consolidated financial statements.

ITEM 2. PROPERTIES.

  The Company occupies, pursuant to leases expiring in 2000, office,
laboratory and manufacturing space near Philadelphia, Pennsylvania and in
Portland, Oregon. The space in Portland, Oregon is shared by the Company's
health products and therapeutic development segments. The Pennsylvania space
is occupied by the Company's instrument manufacturing subsidiary, a part of
its health products segment.

  Although the premises currently occupied are suitable for the Company's
present requirements, the Company believes that other equally suitable
premises are readily available.

ITEM 3. LEGAL PROCEEDINGS.

  There are no pending material legal proceedings to which the Company is a
party or to which any of its property is subject.

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

  At the Company's 1999 Annual Meeting of Stockholders held on December 2,

ITEM 5. MARKET FOR REGISTRANT'S COMMON STOCK AND RELATED STOCKHOLDER MATTERS.

  The Company's common stock is traded on the Nasdaq Stock Market's National
Market and the French stock market, Le Nouveau Marche, under the symbol
"OXIS".

  Recent quarterly high and low sales prices of the Company's common stock on
the NASDAQ Stock Market are as follows:

</TABLE>

  The Company has an estimated 6,000 shareholders, including approximately
2,900 shareholders who hold their shares in street name. The Company utilizes
its assets to develop its business and, consequently, has never paid a
dividend and does not expect to pay dividends in the foreseeable future.

  The Company was notified by NASDAQ that it was not in compliance with
certain NASDAQ requirements for continued listing on the NASDAQ National
Market. Specifically, the Company failed to meet the requirements for
maintaining (1) a minimum bid price of $1.00, (2) market value of public float
greater than or equal to $5,000,000, and (3) minimum net tangible assets of at
least $4,000,000. NASDAQ staff notified the Company that it had determined to
delist the Company's common stock from the NASDAQ National Market. However,
the Company requested an oral hearing to appeal the staff's determination to a
NASDAQ Listing Qualifications Panel (the "Panel"), and such hearing was held
on February 10, 2000.

  Subsequent to the NASDAQ staff's determination, the trading price of the
Company's common stock has increased. As of February 29, 2000, the closing bid
price of the Company's common stock had exceeded the $1.00 minimum every
trading day since December 23, 1999. In addition, subsequent to the Panel's
hearing, the Company has sold equity securities with net proceeds of
approximately $4,580,000.

  The Panel determined that the Company has complied with the $1.00 minimum
bid price and $5,000,000 market value of public float requirements. However,
the Panel has required that on or before April 14, 2000, the Company make a
public filing evidencing a minimum of $8,000,000 in net tangible assets. The
filing is to contain a February 29, 2000 balance sheet with pro forma
adjustments for any significant events or transactions occurring on or before
the filing date.

  Notwithstanding these favorable events, no assurances can be given that the
Company will be able to meet the $8,000,000 requirement or that the common
stock will remain listed on the NASDAQ National Market. If the Company's
common stock ceases to be listed on the NASDAQ National Market, such failure
to be listed could have a material adverse effect on the transferability of
the common stock, and may have a material adverse effect on the value of the
common stock as well.

  As explained under the caption "ACQUISITIONS" in Management's Discussion and
Analysis of Financial Condition and Results of Operations below, the Company
made significant acquisitions during 1995 and 1997 that affect the
comparability of the amounts reflected in the table above.

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

Acquisitions

  In July 1995, the Company acquired Therox Pharmaceuticals, Inc. ("Therox")
through an exchange of stock. Therox was merged into a wholly-owned subsidiary
of the Company. The acquisition of Therox provided the Company with a
technology portfolio complementary to its novel therapeutics for treatment of
free radical associated diseases together with university relationships and
seven patents.

  On December 31, 1997, the Company acquired Innovative Medical Systems Corp.
("IMS"). The name of IMS was changed to OXIS Instruments, Inc. during 1998.
OXIS Instruments, Inc., develops, manufactures, markets and sells medical
instruments.

  The acquisitions described above were completed through the exchange of
stock and were accounted for as purchases; accordingly, the acquired assets
and liabilities were recorded at their estimated fair values as of the dates
of the acquisitions.

  Because the acquisitions have been accounted for as purchases, the Company's
consolidated results of operations include the operating results of the
acquired businesses from the dates of acquisition only. Therefore, the results
of Therox's operations have been included in the consolidated statements of
operations from July 19, 1995, and the results of IMS' operations are included
in the Company's consolidated statement of operations beginning January 1,
1998.

  Costs relating to the acquisitions, the Company's more complex corporate
structure and the increased research and development investments have placed
significant demand on the Company's limited management and financial
resources. See "Financial Condition, Liquidity and Capital Resources" below.

Financial Condition, Liquidity and Capital Resources

  The Company's working capital decreased during 1999 from $3,030,000 as of
December 31, 1998 to $924,000 as of December 31, 1999. This decrease in
working capital resulted primarily from the net loss for

                                      11
<PAGE>

1999 ($4,447,000 less non-cash charges of $1,268,000), offset by a $472,000
increase in working capital resulting from the sale of land and building
(proceeds of $1,959,000 less debt repayment of $1,487,000).

  Cash and cash equivalents decreased from $2,575,000 at December 31, 1998 to
$789,000 at December 31, 1999.

  The Company expects to continue to report losses in 2000 as the level of
expenses is expected to continue to exceed revenues. The Company can give no
assurances as to when and if its revenues will exceed its expenses.

  In March 2000, the Company sold 1,010,868 shares of its common stock
together with warrants to purchase 2,021,736 shares of common stock in a
private placement. Net proceeds from the sale were approximately $4,580,000.
The terms of the private placement allow additional closings, and the Company
expects to sell additional securities in this private placement before the end
of the first quarter of 2000. The Company expects that additional capital will
be required during 2000 to continue operating in accordance with its current
plans. If the Company is unable to generate additional funding through an
increase in revenues, additional borrowings or raising additional capital
during 2000, it intends to curtail its operations through the reduction of
personnel and facility costs and by reducing its research and development
efforts; however, no assurances can be given that it will be able to do so. If
the Company were to be unable to sufficiently curtail its costs in such a
situation, it might be forced to seek protection of the courts through
reorganization, bankruptcy or insolvency proceedings.

  See the information under the heading "RISK FACTORS" in Item 1 for a further
discussion of these matters. For more information concerning the Company's
ability to continue as a going concern, see Note 1 to the consolidated
financial statements.

  While the Company believes that its new products and technologies show
considerable promise, its ability to realize significant revenues therefrom is
dependent upon the Company's success in developing business alliances with
biotechnology and/or pharmaceutical companies that have the required resources
to develop and market certain of these products. There is no assurance that
the Company's effort to develop such business alliances will be successful.

Information Systems and the Year 2000

  As is the case with most other companies using computers in their
operations, the Company has addressed the Year 2000 problem. The Company
reviewed its computer hardware and software to determine whether they would
consistently and properly recognize the Year 2000. Certain of the Company's
systems included hardware and packaged software recently purchased from
vendors who represented that these systems were already Year 2000 compliant.

  Other hardware and software used by the Company was identified by the
Company as not being Year 2000 compliant, particularly certain packaged
software used in the Company's accounting systems. Upgrades to certain
software packages used in the Company's accounting and manufacturing systems
have been installed. Most of the hardware and software replacements for
accounting and manufacturing systems required were replacements that would
have been made regardless of the Year 2000 issue.

  The Company has reviewed all of its systems, including embedded technology
in non-information technology systems, which might be affected by the Year
2000. The Company has reviewed communications, security, and environmental
monitoring and control systems as well as certain laboratory and manufacturing
equipment and equipment manufactured for customers.

  The Company has experienced no unusual system problems since the end of 1999
and believes that it has no remaining significant compliance issues. However,
there is no assurance that currently undetected Year 2000 problems will not
arise.

  The Company's total cost for upgrades and replacements of software, older
computer hardware and other systems or components including embedded
technology that might have been affected by the Year 2000 issue was less than
$100,000.

Results of Operations

 Future Divestiture of Assets

  At the direction of the Company's board of directors, the Company is
currently undertaking a restructuring and reorganization under which the non-
therapeutic assets of the Company, including substantially all of the assets
of OXIS Health Products, Inc., are to be divested or spun off and the Company
will be refocused in the area of ethical pharmaceutical development. Although
a formal plan for this divestiture has not been put in place, it is
anticipated that all of the assets that are currently generating revenues for
the Company will either be sold to a third party or spun off to shareholders.
Upon completion of this anticipated restructuring, the Company will no longer
have a source of current revenues. The Company's continued operations will be
dependent upon additional capital financing until such time as revenues can be
generated from its therapeutic development programs.

 Revenues

  The Company's revenues for the past three years consisted of the following:

</TABLE>

  Sales of research assays and fine chemicals declined by $258,000 from
$1,051,000 in 1997 to $793,000 in 1998 due to a decline in sales volumes. The
single product with the largest decline was l-ergothioneine with a decline of
$ 116,000. The Company sells l-ergothioneine in bulk and its sales have been
sporadic. In 1999 sales of research assays and fine chemicals increased by
$305,000 due to an increase in sales volume of assays to measure markers of
oxidative stress and bulk components of those assays.

  The volume of therapeutic drug monitoring assays declined in 1998 as
compared to 1997, resulting in a decrease in sales of $106,000. In 1999 sales
of therapeutic drug monitoring assays increased by $109,000, to $1,547,000.

  Effective June 28, 1999, the Company sold the intellectual property,
contract rights and finished goods inventory relating to its therapeutic drug
monitoring assays. Sales of therapeutic drug monitoring assays for the year
ended December 31, 1999 include $158,000 for the sale of the therapeutic drug
monitoring finished goods inventory to the purchaser of the rights to this
technology. Increased sales volumes to the Company's distributors in the first
six months of 1999 also contributed to the increase. Therapeutic drug
monitoring assay revenues subsequent to June 29, 1999 represent sales of
assays and services to the purchaser of the rights to this technology. Such
revenues in the second half of 1999 were less than the therapeutic drug
monitoring assay sales in the second half of 1998, and are expected to
continue to be less in the near-term future. Revenues from therapeutic drug
monitoring assay sales and related services may terminate at the end of the
third quarter of 2000, when the contract to manufacture product for the
purchaser of the technology expires.

  Sales of medical instruments by the Company began in 1998, following the
acquisition of IMS on December 31, 1997. Revenue from instrument sales and
development declined by $1,158,000 from $2,477,000 in 1998 to $1,319,000 in
1999. This decrease resulted from reduced orders from certain customers for
whom the Company acts as an original equipment manufacturer.

  Sales of bSOD have been made primarily to the Company's Spanish licensee.
The Company sold bulk bSOD to this customer in 1997 and 1999, but not in 1998.
The Company does not yet have any orders for delivery of bulk bSOD subsequent
to 1999. Future sales of bulk bSOD beyond 1999 are largely dependent on the
needs of the Company's Spanish licensee which are uncertain and difficult to
predict and no assurances can be given that the Company will continue to sell
bulk bSOD to its Spanish licensee.

  Sales of Palosein(R), which is sold primarily to veterinary wholesalers in
the United States and Europe declined by $322,000 to $220,000 in 1998. The
decrease in sales resulted from declining sales volumes due to a reduction in
the Company's marketing efforts. Palosein sales increased modestly, to
$237,000 in 1999.

  Revenues from the license and sale of technology in 1999 consist of $911,000
recognized as compensation for the intellectual property and contract rights
relating to the therapeutic drug monitoring assays and $600,000 paid to the
Company for the assignment of the Company's patents relating to polyalkylene
glycol technology.

 Costs and Expenses

  Cost of sales increased from 66% of product sales in 1997 to 83% of product
sales in 1998. The 1998 increase in cost of sales as a percentage of product
sales was due primarily to low product margins on sales of medical instruments
in 1998. Cost of sales in 1999 decreased slightly to 82% of sales. Improved
margins in 1999 on sales of research assays and therapeutic drug monitoring
assays were mostly offset by the excess ($368,000) of the cost of technology
sold over the proceeds from the sale of technology and an increase in
instrument manufacturing costs as a percentage of instrument sales, which
resulted from the decline in instrument sales volumes. The Company's cost of
sales includes amortization of purchase price adjustments (primarily
technology) acquired in 1994 and 1997 (amortization of $725,000 in 1997,
$857,000 in 1998 and $557,000 in 1999). Excluding amortization of purchase
adjustments and excluding technology sales and the cost of technology sales in
1999, the Company's cost of sales as a percentage of sales was 51% in 1997,
66% in 1998 and 72% in 1999.

  The Company has taken steps to reduce the fixed costs of its medical
instruments manufacturing operation in early 1999 by selling the facility and
leasing back a portion of the space. However, the Company believes that for
current production volumes it would be difficult to further reduce
manufacturing costs. Therefore, significant improvements in product margins
for both medical instruments and diagnostic and research assays are dependent
on increases in sales volumes.

  Cost of technology sold in 1999 represents the carrying value of the
technology relating to the therapeutic drug monitoring assays that was sold.

  Research and development costs increased by $55,000, from $4,319,000 in 1997
to $4,374,000 in 1998. Decreases in 1998 due to cost reductions of the
Company's French subsidiary ($352,000) and a decrease in expenses relating to
clinical studies of the Company's lead therapeutic program ($189,000) were
offset by a $585,000 charge to write down the carrying value of equipment in
the French subsidiary's research facility following the Company's decision to
close that facility. Research and development costs decreased by $1,973,000 in
1999, to $2,401,000. The decrease in 1999 resulted primarily from the closure
of the French research facility in the first half of 1999 and further
reductions in expenditures on therapeutic development projects while the
Company sought additional funds for its therapeutic development programs. As a
result of the closure, expenses of the French research facility were reduced
from $2,378,000 in 1998 (including the $585,000 write-down of equipment) to
$1,058,000 in 1999, a reduction of $1,320,000.

  Sales, general and administrative expenses increased by $937,000 in 1998,
from $2,618,000, to $3,555,000, primarily due to the sales, general and
administrative expenses of OXIS Instruments, Inc., acquired by the Company on
December 31, 1997. In 1999 sales, general and administrative expenses
decreased by $270,000, to $3,285,000. The decrease in 1999 was mostly due to
reductions in compensation expense.


                                      14

 Interest Income and Expense

  Interest income increased by $87,000, from $78,000 in 1997 to $165,000 in
1998 due to an increase in funds available for short-term investment, then
declined to $57,000 in 1999 as funds from the 1998 private placement of
securities were spent.

  Interest expense increased to $298,000 in 1998 from $151,000 in 1997 due
primarily to the increased debt assumed upon the acquisition of Innovative
Medical Systems Corp at the of 1997. Interest expense decreased in 1999 to
$94,000 due primarily to the payment of long-term debt in connection with the
sale of land and buildings in February 1999.

 Net Loss

  The Company incurred net losses in 1997, 1998 and 1999 and does not expect
to be profitable in the foreseeable future.

  Lower profit margins and increased sales, general and administrative
expenses resulted in a $1,978,000 increase in the net loss in 1998 as compared
to 1997. The decrease in net loss per share in 1998 is primarily due to the
increase in the weighted average number of shares outstanding. The Company's
net loss in 1999 was reduced by $2,682,000 as compared to 1998 due primarily
to the reduction of research and development costs.

  The Company expects to incur a substantial net loss for 2000. If the Company
develops substantial new revenue sources or if substantial additional capital
is raised through further sales of securities (See Financial Condition,
Liquidity and Capital Resources), the Company plans to continue to invest in
research and development activities and incur sales, general and
administrative expenses in amounts greater than its anticipated near-term
product margins. If the Company is unable to raise sufficient additional
capital or to develop new revenue sources, it will have to cease, or severely
curtail, its operations. In this event, while expenses will be reduced,
expense levels, and the potential write down of various assets, would still be
in amounts greater than anticipated revenues.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA.

                         INDEPENDENT AUDITORS' REPORT

  To the Board of Directors and Shareholders of
  OXIS International, Inc.:

    We have audited the accompanying consolidated balance sheets of OXIS
  International, Inc. and subsidiaries as of December 31, 1999 and 1998, and
  the related consolidated statements of operations and comprehensive loss,
  shareholders' equity and cash flows for each of the three years in the
  period ended December 31, 1999. Our audits also included the financial
  statement schedule listed in Item 14(d) on Form 10-K. These financial
  statements and financial statement schedule are the responsibility of the
  management of OXIS International, Inc. Our responsibility is to express an
  opinion on these financial statements and financial statement schedule
  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 consolidated
  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, such financial statements present fairly, in all material
  respects, the financial position of OXIS International, Inc. and
  subsidiaries at December 31, 1999 and 1998, and the results of their
  operations and their cash flows for each of the three years in the period
  ended December 31, 1999, in conformity with generally accepted accounting
  principles. Also, in our opinion, such financial statement schedule, when
  considered in relation to the basic consolidated financial statements taken
  as a whole, presents fairly in all material respects the information set
  forth therein.

    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 incurred losses in each of the last
  three years, and at December 31, 1999, the Company had an accumulated
  deficit of $49,750,000, raising substantial doubt about its ability to
  continue as a going concern. Management's plans concerning these matters
  are also described in Note 1. The financial statements do not include any
  adjustments that might result from the outcome of this uncertainty.

                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                 Years ended December 31, 1999, 1998 and 1997

1. Description of Business and Basis of Presentation

  OXIS International, Inc. (the "Company") develops, manufactures and markets
selected therapeutic and diagnostic products and medical instruments. The
Company's research and development efforts are concentrated principally in the
development of products to diagnose, treat and prevent diseases associated
with free radicals and reactive oxygen species. The Company is headquartered
in Portland, Oregon and has an instrument manufacturing facility near
Philadelphia, Pennsylvania.

  Therapeutic drug monitoring assays are manufactured by the Company in the
United States and were sold to hospital clinical laboratories and reference
laboratories by an in-house sales force and a network of distributors both
within and outside the United States. Subsequent to June 1999, the Company has
been manufacturing therapeutic drug monitoring assays pursuant to a contract
with the purchaser of the therapeutic drug monitoring technology (see Note 8).
Assays to measure markers of oxidative stress are manufactured by the Company
in the United States and are sold directly to researchers and to distributors
for resale to researchers, primarily in Europe, the United States and Japan.
Medical instruments are manufactured in the United States and are sold to
distributors and other customers both within and outside the United States.
The Company also sells pharmaceutical forms of superoxide dismutase (SOD) for
human and veterinary use.

  At the direction of the Company's board of directors, the Company is
currently undertaking a restructuring and reorganization under which the non-
therapeutic assets of the Company, including substantially all of the assets
of OXIS Health Products, Inc., are to be divested or spun off and the Company
will be refocused in the area of ethical pharmaceutical development. Although
a formal plan for this divestiture has not been put in place, it is
anticipated that all of the assets that are currently generating revenues for
the Company will either be sold to a third party or spun off to shareholders.
Upon completion of this anticipated restructuring, the Company will no longer
have a source of current revenues. The Company's continued operations will be
dependent upon additional capital financing until such time as revenues can be
generated from its therapeutic development programs.

  These financial statements have been prepared on a going concern basis which
contemplates the realization of assets and the satisfaction of liabilities in
the normal course of business. The Company has incurred net losses in each of
the last three years and at December 31, 1999 had an accumulated deficit of
$49,750,000. These factors, among others, may indicate that the Company may be
unable to continue as a going concern for a reasonable period of time. These
financial statements do not include any adjustments relating to the
recoverability and classification of recorded asset amounts or the amounts and
classification of liabilities that may be necessary should the Company be
unable to continue as a going concern. The Company's continuation as a going
concern is contingent upon its ability to obtain additional financing, and to
generate revenue and cash flow to meet its obligations on a timely basis.

  In March 2000, the Company sold 1,010,868 shares of its common stock
together with warrants to purchase 2,021,736 shares of common stock in a
private placement. Net proceeds from the sale were approximately $4,580,000.
The terms of the private placement allow additional closings, and the Company
expects to sell additional securities in this private placement before the end
of the first quarter of 2000. The Company expects that additional capital will
be required during 2000 to continue operating in accordance with its current
plans. If the Company is unable to generate additional funding through an
increase in revenues, additional borrowings or raising additional capital
during 2000 it intends to curtail its operations through the reduction of
personnel and facility costs and by reducing its research and development
efforts; however, no assurances can be given that it will be able to do so. If
the Company were to be unable to sufficiently curtail its costs in such a
situation, it might be forced to seek protection of the courts through
reorganization, bankruptcy or insolvency proceedings.

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                 Years ended December 31, 1999, 1998 and 1997


  The Company was notified by NASDAQ that it was not in compliance with
certain NASDAQ requirements for continued listing on the NASDAQ National
Market. Specifically, the Company failed to meet the requirements for
maintaining (1) a minimum bid price of $1.00, (2) market value of public float
greater than or equal to $5,000,000, and (3) minimum net tangible assets of at
least $4,000,000. NASDAQ staff notified the Company that it had determined to
delist the Company's common stock from the NASDAQ National Market. However,
the Company requested an oral hearing to appeal the staff's determination to a
NASDAQ Listing Qualifications Panel (the "Panel"), and such hearing was held
on February 10, 2000.

  Subsequent to the NASDAQ staff's determination, the trading price of the
Company's common stock has increased. As of February 29, 2000, the closing bid
price of the Company's common stock had exceeded the $1.00 minimum every
trading day since December 23, 1999.

  The Panel determined that the Company has complied with the $1.00 minimum
bid price and $5,000,000 market value of public float requirements. However,
the Panel has required that on or before April 14, 2000, the Company make a
public filing evidencing a minimum of $8,000,000 in net tangible assets. The
filing is to contain a February 29, 2000 balance sheet with pro forma
adjustments for any significant events or transactions occurring on or before
the filing date.

2. Significant Accounting Policies

  Principles of consolidation--The accompanying financial statements include
the accounts of the Company as well as its subsidiaries. The functional
currency of the Company's French subsidiary is the French franc. The French
subsidiary's assets and liabilities are translated at the exchange rate at the
end of the year, and its statement of operations is translated at the average
exchange rates during each year. Gains and losses resulting from foreign
currency translation are recorded as other comprehensive income or loss and
accumulated as a separate component of shareholders' equity. All significant
intercompany balances and transactions are eliminated in consolidation.

  Cash equivalents consist of money market accounts with commercial banks.

  Inventories are stated at the lower of cost or market. Cost has been
determined by using the first-in, first-out method. Inventories at December
31, 1999 and 1998, consisted of the following:

  Property, plant and equipment is stated at cost. Depreciation of equipment
is computed using the straight-line method over estimated useful lives of
three to ten years. Building and building improvements have been depreciated
using the straight-line method over estimated useful lives of thirty years.
Leasehold improvements are amortized over the shorter of five years or the
remaining lease term.

</TABLE>

  In February 1999, all of the Company's land, building and improvements with
a net book value of $1,894,000 was sold for a gross sales price of $2,062,000.

  In the first half of 1999 the Company closed its research and development
facility in France. Substantially all research and development activities
being carried on by the Company's French subsidiary were ceased in early 1999.
As of December 31, 1998, the carrying value of that equipment was written down
to its estimated net realizable value, resulting in a $585,000 charge to
research and development expense in 1998. This charge is included in the
segment loss for the therapeutic development segment in the segment
information in Note 8.

  Technology--Technology for developed products acquired in business
combinations is amortized over estimated useful lives of seven to ten years.
Accumulated amortization of technology for developed products was $712,000 as
of December 31, 1999, and $3,113,000 as of December 31, 1998. The Company
periodically reviews net cash flows from sales of products and projections of
net cash flows from sales of products on an undiscounted basis to assess
recovery of intangible assets.

  Stock options--The Company applies the intrinsic value based method
described in Accounting Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees", in accounting for its stock options.

  Revenue recognition--The Company manufactures, or has manufactured on a
contract basis, products that are sold to customers. The Company recognizes
product sales upon shipment of the product to the customer. The Company also
develops and acquires technology that is either used in the Company's
operations or sold, licensed or assigned to third parties. The Company
recognizes revenue upon the sale or assignment of technology to third parties.

  Income taxes--Deferred income taxes, reflecting the net tax effects of
temporary differences between the carrying amount of assets and liabilities
recognized for financial reporting purposes and the amounts recognized for
income tax purposes, are based on tax laws currently enacted. A valuation
allowance is established when necessary to reduce deferred tax assets to the
amount expected to be realized.

  Net loss per share--Net loss per share is computed based upon the weighted
average number of common shares outstanding ("basic") and, if dilutive, the
incremental shares issuable upon the assumed exercise of stock options or
warrants and the assumed conversion of preferred stock ("dilutive"). Due to
the net losses in each of the last three years, the computation of dilutive
net loss per share is antidilutive and therefore is the same as basic. If the
Company had been profitable in 1999 approximately 12,000 additional shares
would have been included in the calculation of dilutive earning per share due
to the dilutive effect of the assumed exercise of stock options.

                 Years ended December 31, 1999, 1998 and 1997


  Restatement to reflect reverse stock split--As described in Note 6, a one-
for-five reverse split of the Company's common stock became effective October
21, 1998. All common share and per common share amounts have been restated to
reflect the reverse split.

  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 and
disclosure of contingent assets and liabilities at the date of the financial
statements and the reported amounts of sales and expenses during the reporting
period. Actual results could differ from those estimates.

  Fair value of financial instruments--The carrying amount reported in the
balance sheet for cash and cash equivalents, accounts receivable, notes
payable, customer deposits and accounts payable approximates fair value due to
the short-term nature of the accounts. The carrying amount reported in the
balance sheet for long-term debt reflects fair value based on approximate
rates that would currently be available to the Company.

3. Business Combination

  On December 31, 1997, the Company consummated the acquisition of Innovative
Medical Systems Corp. ("IMS") pursuant to a transaction whereby the Company
acquired all of the outstanding stock of IMS in exchange for 200,000 shares of
the Company's common stock issued immediately and additional common shares to
be issued. The name of IMS was changed to OXIS Instruments, Inc. during 1998.
The acquisition of IMS has been recorded as a purchase and, accordingly, the
acquired assets and liabilities were recorded at their estimated fair values
as of the date of acquisition. The aggregate purchase price of $1,559,000 has
been allocated to the assets and liabilities acquired. The purchase price
represents the sum of (1) 200,000 common shares issued times the average per
share closing price of the Company's common stock for the three days before
and after November 1, 1997, the date on which the two companies reached
agreement on the purchase price and (2) the present value of minimum future
issuances of common stock aggregating $1,250,000. Additional common shares are
to be issued to former IMS shareholders annually through 2003. The number of
additional common shares which may be issued to former IMS shareholders
depends, among other things, on future annual revenues of OXIS Instruments,
Inc., through 2002 and on the market price of the Company's common stock.
Based on the revenues of OXIS Instruments, Inc. for 1998 and 1999, no
additional common shares have been required. Management does not expect the
future revenues of OXIS Instruments, Inc. to reach levels that would increase
payments to former IMS shareholders beyond the minimum. The total number of
additional shares of common stock which may be issued subsequent to December
31, 1999, to former IMS shareholders in exchange for their IMS stock is
limited to a maximum of 878,009 shares.

  During 1998 the Company completed its allocation of the purchase price of
IMS. The cost of the acquisition of IMS has been allocated to the assets
acquired and liabilities assumed as follows:

  Because the acquisition has been recorded as a purchase, the Company's
consolidated results of operations for 1997 do not include the operating
results of the acquired company.

</TABLE>

  The note payable to Commerce Bank is the outstanding balance pursuant to a
$450,000 line of credit and bears interest at the bank's prime rate plus 1.75%
(10.50% at December 31, 1999). The line of credit expires April 1, 2000. The
liability is secured by inventory and accounts receivable of OXIS Instruments,
Inc. and is guaranteed by a former IMS shareholder.

  The 8% unsecured notes are due to shareholders of the Company. The notes
were due in May 1997. The remaining noteholders are indebted to the Company
under the terms of a separate indemnification agreement related to a
contingency associated with a previous purchase. Of the $320,000 liability,
$160,000 was converted into equity securities in March 2000. Payment of the
remaining note has been deferred pending the outcome of ongoing discussions
with the noteholder.

5. Long-Term Debt

  Long-term debt at December 31, 1999 and 1998 consisted of the following:

6. Shareholders' Equity

  Common Stock. On May 20, 1997, the Company issued 1,800,000 shares of its
common stock pursuant to an underwriting agreement with certain underwriters
in France. The underwriters purchased the stock at a price of 23 French francs
per share (an aggregate of $7,328,000). The newly-issued shares have been
listed on the French stock market, Le Nouveau Marche, and on the NASDAQ
National Market System.

  In the second and third quarters of 1998 the Company completed a private
placement of its common stock together with warrants to a series of
institutional investors ("units"). The units, consisting of one share of
common stock plus a warrant to purchase one share of common stock, were priced
at the NASDAQ closing price

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                 Years ended December 31, 1999, 1998 and 1997

the day prior to the signing of the subscription agreements. A total of
1,985,678 common shares and warrants to purchase an equal number of common
shares were issued in exchange for gross proceeds of $8,181,000 in cash and
conversion of $778,000 of short-term notes and accrued interest payable. The
exercise price of each warrant is equal to 120% of the price paid per unit.

  At the Company's Annual Meeting of Stockholders held on July 13, 1998, the
stockholders approved proposals to increase the authorized number of common
shares to 95,000,000 and reduce the par value of the Company's common stock to
$.001. Following the meeting, the number of authorized shares of common stock
was increased and the par value was reduced, accordingly. The stockholders
also approved a proposal authorizing the Company's Board of Directors at its
discretion to effect a one-for-five reverse stock split at any time prior to
the Company's 1999 Annual Meeting of Stockholders. In September 1998 the
Company's Board of Directors approved the reverse split, which became
effective October 21, 1998. All common share and per common share amounts have
been restated to reflect the one-for-five reverse stock split.

  Preferred Stock--Terms of the preferred stock are to be fixed by the Board
of Directors at such time as the preferred stock is issued. During 1998,
214,194 shares of Series B Preferred Stock were converted into 42,838 shares
of common stock. The remaining 428,389 outstanding shares of Series B
Preferred Stock are convertible into and have voting rights equivalent to
85,678 shares of common stock. The Series B Preferred Stock has certain
preferential rights with respect to liquidation and dividends.

  The shares of Series C Preferred Stock are convertible into shares of the
Company's common stock at the option of the holders at any time. The
conversion ratio is based on the average closing bid price of the common stock
for the fifteen consecutive trading days ending on the date immediately
preceding the date notice of conversion is given, but cannot be less than .20
nor more than .2889 common shares for each Series C Preferred share. The
conversion ratio may be adjusted under certain circumstances such as stock
splits or stock dividends. The Company has the right to automatically convert
the Series C Preferred Stock into common stock if the average closing bid
price of the Company's common stock on the NASDAQ National Market for 15
consecutive trading days exceeds $13.00. Each share of Series C Preferred
Stock is entitled to the number of votes equal to .26 divided by the average
closing bid price of the Company's common stock during the fifteen consecutive
trading days immediately prior to the date such shares of Series C Preferred
Stock were purchased. Through December 31, 1999, 1,165,544 shares of Series C
Preferred Stock have been converted into common stock. As of December 31,
1999, 608,536 shares of Series C Preferred Stock remained outstanding.

  During 1998 the Company entered into a settlement agreement with the holder
of the remaining 700 outstanding shares of Series D Preferred Stock whereby
such holder and the Company released any and all claims either may have
against the other with respect to such Series D Preferred Stock, and the
Company paid the holder $700,000 cash. The holder has subsequently returned
the Series D certificate which has been cancelled.

  Stock Warrants--In connection with the issuance of common stock, 8%
Convertible Subordinated Debentures, and Series B, C and E Preferred Stock,
the Company has issued to its placement agents warrants to purchase 122,911
shares of common stock at prices ranging from $6.875 to $16.25 per share.
These warrants all remained outstanding and were exercisable at December 31,
1999. They expire between May 2000 and December 2001.

  A warrant to purchase 162,025 common shares at $12.50 per share was issued
to the purchaser of the Company's Series D Preferred Stock. This warrant was
immediately exercisable and remained outstanding as of December 31, 1999. It
expires in May 2001.

  Warrants to purchase 60,000 common shares were issued to the purchasers of
the secured convertible term notes in October 1996. The warrants have an
exercise price of $3.05 per share and expire on October 11, 2001. They were
immediately exercisable and remained outstanding as of December 31, 1999.

  Warrants to purchase 1,985,678 common shares at exercise prices of $5.25 to
$6.75 that were issued in connection with the sale of common shares during
1998 remained outstanding at December 31, 1999. These warrants became
exercisable during 1999 and expire in April and May 2003.

  Stock Options--The Company has a stock incentive plan under which 1,365,000
shares of the Company's common stock are reserved for issuance. The plan
permits granting stock options to acquire shares of the Company's common
stock, awarding stock bonuses of the Company's common stock, and granting
stock appreciation rights. Options granted pursuant to the Plan have a maximum
term of ten years; vesting is determined by the Compensation Committee of the
Company's board of directors. Options granted through 1999 have had vesting
requirements of up to four years. The plan permits grants of options at less
than the fair market value of the underlying shares on the date of the grant,
but through 1999 no such options have been issued. Options granted and
outstanding under the plan are summarized as follows:

  The weighted average fair value as of the option date was computed to be
$.24 per share for options issued during 1999, $1.72 per share for options
issued during 1998 and $4.15 per share for options issued during 1997.

  At December 31, 1998 and 1999 options remained outstanding that were not
issued pursuant to the Company's stock incentive plan granting the holder the
right to acquire 7,000 shares of the Company's common stock at $8.44 per
share.

7. Income Taxes

  Income Tax Provision--Income tax provisions were not necessary in 1999, 1998
and 1997 due to net losses.

  Deferred Taxes--Deferred taxes reflect the net tax effects of (a) temporary
differences between the carrying amounts of assets and liabilities for
financial reporting purposes and the amounts used for income tax purposes, and
(b) operating losses and tax credit carryforwards.

  The tax benefits ($5,136,000) of the net operating losses of $15,410,000
which existed at the date of acquisition (September 7, 1994) of the French
subsidiary will be recorded as a reduction of income tax expense when and if
realized. Due to the closure of the French subsidiary's operations in early
1999, it is unlikely that the Company will ever realize any benefit from the
French subsidiary's operating loss carryforwards.

  The tax benefits ($351,000) of the net operating losses of $1,032,000 which
existed at the date of acquisition (December 31, 1997) of IMS will be recorded
as a reduction of the net unamortized balance of property, plant and equipment
and intangible assets of $627,000 when and if realized.

  Statement of Financial Accounting Standards No. 109 requires that the tax
benefit of net operating losses, temporary differences and credit
carryforwards be recorded as an asset to the extent that management assesses
that realization is "more likely than not." Realization of the future tax
benefits is dependent on the Company's ability to generate sufficient taxable
income within the carryforward period. Because of the Company's recent history
of operating losses, management has provided a valuation allowance equal to
its net deferred tax assets.

  Tax Carryforwards--At December 31, 1999, the Company had net operating loss
carryforwards of approximately $10,787,000 to reduce United States federal
taxable income in future years, and research and development tax credit
carryforwards of $676,000 to reduce United States federal taxes in future
years. In

  Utilization of the United States tax carryforwards is subject to certain

Revenue Service guidelines) in ownership of the Company.

8. Operating Segments

  The Company is organized into two reportable segments--health products and
therapeutic development. The two segments have different strategic goals and
have been managed separately since 1997. The health products segment
manufactures and sells diagnostic products, medical instruments,
pharmaceutical forms of SOD and other fine chemicals. The therapeutic
development segment operates a drug discovery business focused on development
of new drugs to treat diseases associated with tissue damage from free
radicals and reactive oxygen species.

  The accounting policies of the segments are the same as those described in
the summary of significant accounting policies. The Company accounts for
inter-segment sales at cost. General corporate expenses have been allocated
equally to the health products and therapeutics development segments. Prior to
1998 the assets and liabilities had not been divided between the segments,
therefore interest income and interest expense were allocated equally to the
two segments.

  Effective June 28, 1999, the Company sold the intellectual property,
contract rights and finished goods inventory relating to its therapeutic drug
monitoring assays. Proceeds from the sale consisted of $500,000 cash, a non-
interest bearing note (collected during 1999) and a warrant granting the
Company the right to acquire an equity interest in the purchaser of the
assets.

  The Company recognized $911,000 as compensation for the intellectual
property and contract rights. This amount has been included in sales for 1999.
The Company has entered into an agreement with the purchaser of the
therapeutic drug monitoring assays pursuant to which the Company will continue
to manufacture the products and perform certain other services for the
purchaser through the third quarter of 2000.

  Sales of bSOD to one customer of the Company's health products segment
represents approximately $1,123,000 in 1999 and $1,554,000 in 1997. The
Company had no sales to this customer in 1998. Revenues of the health products
segment in 1999 include $911,000 for the sale of intellectual property and
contract rights, and $606,000 for product sales to the purchaser of the
therapeutic drug monitoring assays.

  Revenues attributed to countries based on the location of customers:

            NOTES TO CONSOLIDATED FINANCIAL STATEMENTS--(Continued)

                 Years ended December 31, 1999, 1998 and 1997


9. Foreign Exchange Risk

  The Company limits its foreign exchange risk by buying and selling bulk bSOD
in a single currency, the Dutch guilder. The Company maintains a bank account
in The Netherlands for receipt and disbursement of Dutch guilders and had the
equivalent of $167,000 and $122,000 in that account at December 31, 1999 and
1998, respectively.

  The Company and its French subsidiary maintained bank accounts in France and
had the equivalent of $71,000 in those accounts at December 31, 1998. The
Company's account in France was closed during 1999. The balance of the French
subsidiary's account was insignificant at December 31, 1999. Foreign currency
transaction gains and losses were not significant.

10. Commitments and Contingencies

  The Company leases its facilities in Oregon and Pennsylvania under operating
leases that both expire in 2000. Lease payments to which the Company is
committed aggregate $141,000 in 2000. Rental expense included in the
accompanying statements of operations was $260,000 in 1999, $341,000 in 1998
and $361,000 in 1997.

  In 1995 the Company consummated the acquisition of Therox Pharmaceuticals,
Inc. ("Therox") pursuant to a transaction wherein Therox was merged with and
into a wholly-owned subsidiary of the Company. In addition to the issuance of
its common stock to Therox shareholders, the Company agreed to make payments
of up to $2,000,000 by the Company to the Therox stockholders based on the
successful commercialization of the Therox technologies. As of December 31,
1999, no additional payments have been made.

  The Company and its subsidiaries are parties to various claims. Although the
Company is unable to predict with certainty whether it will ultimately be
successful in its defense of such claims or, if not, what the impact might be,
management currently believes that disposition of these matters will not have
a materially adverse effect on the Company's consolidated financial
statements.

11. 401(k) Savings Plan

  The Company has a 401(k) savings plan (the "Plan") which covers all United
States employees who meet certain minimum age and service requirements. The
Company's matching contribution to the Plan for each year is 100% of the first
$1,000 of each employee's salary deferral and 33-1/3% of the next $3,000 of
salary deferral. The Company's contributions have not been significant.
