   Some of our statements in this annual report on Form 10-K are forward-
looking statements that involve risks and uncertainties. In making these
statements, we rely on a number of assumptions and make predictions about the
future. Our actual results could differ materially from our expectations for a
number of reasons, including the risks described in the section entitled
"Factors Affecting Our Operating Results, Our Business and Our Stock Price" in
Part II, Item 7 of this annual report. You should not rely unduly on these
forward-looking statements which apply only as of the date of this report. We
undertake no duty to publicly announce or report revisions to these statements

expectations of the future.

Overview

   Targeted Genetics Corporation develops gene therapy products and
technologies for the treatment of acquired and inherited diseases. We have
assembled a broad base of core technologies that we believe has the potential
to address a significant number of these diseases and we believe that we have
expertise that will enable us to develop products based on these technologies.
We have two lead products under development for the treatment of cystic
fibrosis and cancer. We believe that our success in developing these initial
products would demonstrate the value of our core technologies and their
potential to treat numerous other diseases.

   Our business strategy is based on the following five key principles:

   Multiple gene delivery systems. We believe that different disease targets
will require different methods of gene delivery. The best gene delivery method
for a particular disease will depend on the type of cell to be modified, the
duration of gene expression desired and the need for in vivo (inside the body)
or ex vivo (outside the body) delivery. Therefore, our strategy has been to
develop multiple gene delivery systems. Our systems are based on three
different vector technologies: adeno-associated viral (AAV), synthetic and
retroviral. We believe these systems will give us the flexibility to develop
gene therapies for a broader range of diseases than we could develop using a
single gene delivery system.

   Emphasis on product development infrastructure. We believe that an
abundance of basic research is being conducted in the area of gene therapy,
and that those who are capable of translating that research into products will
derive significant value. A great deal of discovery research has been focused
on gene therapy techniques, but much less effort has been focused on the
creation of the product development infrastructure necessary to move concepts
through preclinical studies and clinical trials into the commercial realm.
Therefore, we have focused the overwhelming majority of our efforts on
establishing product development expertise in the areas of preclinical
biology, process development, manufacturing, quality control, quality
assurance, regulatory affairs and clinical trials. We believe that this
product development focus will increase the probability of our reaching the
market with products before our competitors.

   Clinical proof of concept. We believe that by providing strong evidence of
the clinical benefit of our products, we will generate significant value
enhancement for our shareholders. Although most experts believe that gene
therapy will be a powerful approach to treating diseases in the future, many
believe that this is a long-term proposition. We believe that we have two lead
products with significant potential to demonstrate clinical proof of concept
in the near term: tgAAV-CF for cystic fibrosis and tgDCC-E1A for cancer. We
expect both of these products to be in Phase II clinical trials in 2000, with
the possibility of entering pivotal clinical trials in 2001. We believe that
proof of concept in cystic fibrosis and cancer will serve to demonstrate the
value not only of our two lead product candidates but of our AAV and synthetic
gene delivery technologies as well.

   Pipeline development. We believe that there is tremendous long-term
potential for the use of our gene delivery systems to treat additional
diseases. The infrastructure we have built to support the development of
tgAAV-CF and tgDCC-E1A should, over time, to support new products based on our
AAV and synthetic gene

                                       3
<PAGE>

delivery systems. Similarly, the knowledge and expertise we gain in developing
our two initial products should apply to our future products under
development. We believe that we can derive significant future value by
leveraging our infrastructure, knowledge and expertise with additional
pipeline products. Currently, we have ongoing preclinical product development
activities in the areas of hemophilia, rheumatoid arthritis, cardiovascular
disease and HIV vaccines.

   Long-term value retention. We believe that our products under development
have significant long-term potential. Therefore, it is important to us that we
retain a substantial financial interest in the sales of commercial products
that result from our work. For products based on our AAV delivery system, we
intend to retain, at a minimum, manufacturing rights to all products that we
develop. We have retained worldwide commercial rights to tgDCC-E1A. We plan to
maintain our tgDCC-E1A rights and to develop the product internally until we
can enter a collaborative transaction that will allow us to achieve
substantial long-term participation in tgDCC-E1A's potential downstream
commercial revenues.

   The following table summarizes our product development programs:

   In addition to our gene therapy technologies, we have patents and expertise
in cell therapy that may prove to be extremely valuable. Our expertise enables
us to isolate potent disease-specific cytotoxic T lymphocytes (CTLs) from
small samples of patient blood and to efficiently multiply them to large
numbers for reinfusion to the patient. We believe that this technology and
expertise could support development of a series of immunotherapies to treat
infectious diseases and cancer. Key to this technology is our proprietary
Rapid Expansion Method (REM), for which we received our first patent in 1998.
Using REM, we can grow billions of CTLs from individual cloned cells over
several weeks, while preserving the cells' specific disease-fighting
capabilities. We also believe that REM has utility in the areas of genomic
target validation, antigen discovery and vaccine development.

Clinical Product Development Programs

tgAAV-CF

   Cystic fibrosis is the most common single-gene deficiency affecting the
Caucasian population, afflicting approximately 24,000 people in the United
States and 60,000 people worldwide. The disease is caused by a defective
cystic fibrosis transmembrane regulator (CFTR) gene, which results in a build-
up of mucus in the lungs, leading to chronic infections, loss of lung function
and early death. Current treatments for cystic fibrosis relieve only symptoms
of the disease, and cannot cure the disease or stop its progression.

   Based on our research and development to date, we believe that tgAAV-CF may
be superior to other gene therapy approaches for the treatment of cystic
fibrosis, due to the duration of its effect and lack of toxicity. In
preclinical studies in rabbits, we were able to detect expression of the CFTR
gene in the lung for periods of up to six months with no side effects. These
results were supported in similar studies in rhesus monkeys, in which gene
transfer occurred in up to 50% of targeted airway cells and gene expression
persisted for up to six months.

                                       4
<PAGE>

Based on these preclinical data, we began our clinical program in late 1995 to
evaluate the safety and feasibility of using tgAAV-CF as a treatment for
cystic fibrosis lung disease. tgAAV-CF has been granted orphan drug status by
the United States Food and Drug Administration (FDA).

   Our first clinical trial, which began in late 1995, was a Phase I open-
label, single-dose clinical trial at Johns Hopkins University and the
University of Florida. In this trial, we administered tgAAV-CF to eight
cohorts of adult cystic fibrosis patients at increasing dosage levels. We
administered a liquid form of tgAAV-CF to the right lower lobe of the lung,
using a bronchoscope, and to one nostril of each of 18 patients. The results
of the trial indicated that the product was safe with no apparent side
effects. We recently reopened this trial to treat patients at higher dosages.

   Our second clinical trial began in late 1995 at Stanford University. We
designed this trial as a Phase I/II trial, in which tgAAV-CF was administered
to the maxillary sinuses of cystic fibrosis patients with chronic sinusitis.
We completed the Phase I part of this trial, designed as a dose escalation
study, in 1996. A total of ten patients were enrolled and 15 sinuses were
treated, in five cohorts with increasing doses. The results of the trial
indicated that tgAAV-CF was safe and well tolerated with no resulting
inflammatory response or other side effects, even after repeated delivery.
Administration of tgAAV-CF, furthermore, resulted in consistent gene transfer
and persistence of the gene for at least 70 days after treatment. In addition,
the dose level was established for the Phase II part of the trial, in which 23
patients received tgAAV-CF in one sinus and a placebo in the other. The Phase
II part of the trial was completed in mid-1998. The results of the trial
indicated that the drug was safe and well-tolerated in all patients treated,
and that markers of inflammation were reduced in the treated sinuses.

   In December 1998, we began a Phase I clinical trial to test the safety of
aerosol delivery of tgAAV-CF to the whole lungs of CF patients. The clinical
trial, for which patient enrollment was completed in early 2000, was conducted
at three sites: Stanford University, the University of Washington and Harvard
University. We treated twelve patients with a single dose of tgAAV-CF in the
study, three each at four increasing dosage levels. We are compiling and
analyzing data from this study and expect to present the results in the first
half of 2000. We plan to begin a Phase II clinical trial, in which patients
will receive multiple doses of tgAAV-CF, in mid-2000.

   In November 1998, we entered into a license and collaboration agreement
related to tgAAV-CF with Medeva Pharmaceuticals, Inc., a subsidiary of Medeva
PLC (Medeva). Under this agreement, Medeva received exclusive worldwide
marketing rights to tgAAV-CF in exchange for agreeing to provide significant
funding to Targeted Genetics. The section below entitled "Research and
Development Collaborations" provides a detailed description of this
relationship.

tgDCC-E1A

   Cancer is the second leading cause of death in the United States, with over
one million new cases diagnosed each year. Cancer arises when the genetic
pathways that control normal cell growth and division are disrupted. Some of
these pathways are regulated by cellular oncogenes or tumor inhibitor genes.
Cancer can result from the structural alteration and abnormal expression of
cellular oncogenes or from mutation or deletion of tumor inhibitor genes.

   Our product candidate for the treatment of cancer uses our proprietary
synthetic delivery system, called DC-Chol, to deliver the E1A gene locally to
cancer cells. We call this product tgDCC-E1A. E1A is a gene from the
adenovirus type 5, a common cold virus. Dr. Mien Chie Hung and his colleagues
at University of Texas M.D. Anderson Cancer Center (M.D. Anderson) have
performed tests that indicate that E1A can function as an inhibitor of the
HER-2/neu oncogene, which is known to be overexpressed in many cancers.
Preclinical mouse studies indicate that tgDCC-E1A inhibits expression of the
HER-2/neu oncogene, inhibits growth and metastasis of cancer cells and
increases significantly the long-term survival of the mice. We have worldwide
rights, under patents filed by Dr. Hung, to the use of the E1A gene as a tumor
inhibitor.

                                       5
<PAGE>

   Other research, conducted by Dr. Steven Frisch and his colleagues at the
Burnham Institute, has indicated that E1A has other anti-tumor effects
unrelated to the inhibition of HER-2/neu expression. In vitro experiments have
shown that E1A, when introduced to a variety of tumor cells, can alter tumor
cells so that they appear to revert to normal cells and lose their malignant
characteristics. Furthermore, in vivo studies in mice involving tumor cells
not overexpressing HER-2/neu indicated that administration of E1A reduced
tumor growth rates. In pre-clinical studies we also found that E1A makes tumor
cells susceptible to being killed by certain chemotherapeutic agents. We have
worldwide rights to patents filed by Dr. Frisch that are complementary to
those filed by Dr. Hung.

   Our first Phase I clinical trial of tgDCC-E1A began in 1996 at M.D.
Anderson, Rush Presbyterian Medical Center in Chicago (Rush) and Virginia
Mason Medical Center in Seattle. In this trial, patients with ovarian or
breast cancer received weekly doses of tgDCC-E1A for up to six months. We
conducted the trial as an interpatient escalating dose study delivering doses
of tgDCC-E1A into the peritoneal cavity (intestines) of the ovarian cancer
patients and into the pleural cavity (lungs) of the breast cancer patients. We
designed this trial to assess safety, levels of gene transfer and expression
and tumor response. We treated a total of 18 patients through the trial's
completion in early 1998. The results indicated that clinicians can safely
administer the drug in biologically active amounts and that the E1A gene was
present and active in tumor cells. Additionally, in some patients, we observed
decreased levels of HER-2/neu expression and decreased numbers of tumor cells.

   Our second Phase I clinical trial began in early 1997 at M.D. Anderson,
Rush and Wayne State University in Detroit. In this trial, we administered to
patients with inoperable primary head or neck tumors or metastatic breast or
lung tumors up to ten weekly doses of tgDCC-E1A, injected directly into the
tumor. We conducted the trial as an interpatient escalating dose study with
four dose levels and treated a total of 18 patients through the trial's
completion in early 1998. The objectives of the trial were to assess safety,
levels of gene transfer and expression and tumor response. The results
indicated that the drug was safe and that the E1A gene was present and active
in tumor cells. Additionally, in a majority of the patients, tumor growth was
inhibited or treated tumors shrank in size, or both.

   Based on the data obtained from the two Phase I clinical trials described
above, we began a Phase II clinical trial of tgDCC-E1A for head and neck
cancer in October 1998. We completed this trial, which we conducted at five
cancer centers, in the fall of 1999, treating a total of 23 patients. We are
compiling and analyzing the data from the study and expect to present the
results in the first half of 2000.

   In late 1999, we began the first in a series of clinical trials testing
tgDCC-E1A administered in combination with chemotherapeutic drugs. In this
Phase I clinical trial, we will treat ovarian cancer patients with advanced
stage disease with a combination of tgDCC-E1A, Taxol and Cisplatin, at
increasing dosage levels. We anticipate enrolling up to 21 patients in this
study, which is ongoing at the University of Arizona and M.D. Anderson. We
expect to complete patient enrollment in this clinical trial by the end of
2000. Also in 2000, we plan to begin additional clinical trials of tgDCC-E1A
in combination with chemotherapeutic drugs in head and neck cancer and,
potentially, other cancers.

Preclinical Product Development Programs

Hemophilia A

   Hemophilia A is a hereditary disorder caused by the absence or severe
deficiency of Factor VIII, a blood protein essential for proper coagulation.
According to the National Hemophilia Foundation, approximately 14,000 people
in the United States live with hemophilia A. Worldwide, there are
approximately 50,000 hemophilia A patients. Hemophilia A patients face
spontaneous, uncontrolled internal bleeding that can lead to restricted
mobility, pain and, if left untreated, death. These serious, acute bleeding
incidents are generally treated with either recombinant or naturally-derived
Factor VIII protein. If slow chronic bleeding is not treated, however,
progressive, irreparable physical damage can result. In addition, both
recombinant and naturally-derived Factor VIII protein is expensive, and the
naturally-derived protein from human serum may carry blood-borne pathogens,
such as HIV, EBV (Epstein Barr Virus) and hepatitis C.

                                       6
<PAGE>

   We believe that there is strong rationale for the development of a gene
therapy product that could be administered prophylactically to hemophilia A
patients in order to prevent bleeding incidents for the following reasons:

  .  the disease results from a single gene defect that is well understood
     and has been validated by the development of a protein therapy;

  .  overproduction of Factor VIII has not been shown to be harmful,
     therefore eliminating the need for precise regulation of gene
     expression;

  .  researchers believe that production of just 5% of normal levels of
     Factor VIII could stop the chronic bleeding incidents in hemophilia A
     patients;

  .  high costs and safety issues prevent protein therapies from being
     administered prophylactically, thereby creating an unmet need among
     hemophilia patients; and

  .  the current global market for Factor VIII protein products, which is
     estimated at $1.2 billion, not including hospitalization costs,
     represents a significant market opportunity.

   We also believe that AAV vectors represent the most promising means of
creating an effective gene therapy product for the treatment of hemophilia A.
The characteristics of AAV vectors, including the demonstrated safety profile
and their ability to persist in cells and express genes for extended periods
of time, should provide important advantages compared to competing gene
delivery methods. Additionally, AAV vectors have been shown to express genes
efficiently in liver cells, the site from which Factor VIII protein is
normally produced in the human body. We have invested in significant
infrastructure to support the development of tgAAV-CF, which we believe can be
efficiently adapted also to the development of a Factor VIII AAV vector
product.

   In 1999, we entered into an agreement with the University of North Carolina
at Chapel Hill to gain exclusive access to patent applications filed on a
novel approach for using AAV vectors to deliver the Factor VIII gene. In its
native form, the Factor VIII gene is too large to fit into an AAV vector. Dr.
Christopher Walsh of UNC developed a vector that contains a smaller version of
the Factor VIII gene, one that is missing a portion of the gene called the "B-
domain." In the human body, when clotting activity is required, a natural
process removes the B-domain to create an active Factor VIII protein. Dr.
Walsh's vector has been shown to produce active Factor VIII protein in a mouse
model. Furthermore, in the same model, Dr. Walsh has shown that when the gene
is transferred to liver cells, the gene expression persists for at least 12
months and the level of Factor VIII released into the bloodstream reached up
to 27 percent of normal levels. Based on these encouraging data, we are
collaborating with Dr. Walsh to move his AAV-Factor VIII vector into clinical
trials as quickly as possible. We expect to begin a Phase I clinical trial in
2001. We intend to design this clinical trial to establish safety and measure
Factor VIII protein levels that result from the administration of various
dosage levels of the product.

Metastatic Cancer

   Based on our clinical testing of tgDCC-E1A, we believe that we have
demonstrated the potential of E1A as a tumor inhibitor. Therefore, we believe
that if we were able to deliver E1A systemically and reach tumor sites
throughout the body, we could significantly expand the utility of E1A as a
cancer treatment. We have developed a new formulation of E1A, called tgLPD-
E1A, that we believe has the potential to target cancer cells when
administered systemically.

   tgLPD-E1A is based on a gene delivery vehicle called LPD that was developed
in collaboration with Dr. Leaf Huang of the University of Pittsburgh. The LPD
formulation, which contains lipid, polycation and DNA, results in the
formation of small, stable particles encapsulated in a lipid shell. In 1999,
we conducted tests of tgLPD-E1A in a mouse model of human breast cancer
tumors. In this study, conducted in collaboration with Dr. Mien Chie Hung of
M.D. Anderson, we administered tgLPD-E1A systemically to evaluate its ability
to inhibit tumor growth. The results indicated that the impact of tgLPD-E1A on
tumor growth was comparable to the impact observed with administration of
Taxol. Additionally, in mice that received both Taxol and tgLPD-E1A, the
inhibition of tumor growth was significantly better than with either agent
alone. Based on these encouraging results, we are preparing to begin a Phase I
clinical trial of tgLPD-E1A by 2001.

Rheumatoid Arthritis

   Our interest in developing a gene therapy product for the treatment of
rheumatoid arthritis stems from our origins as a spinout from Immunex
Corporation. As part of that spinout, Immunex granted us a license to certain
Immunex technology for use in the field of genetic therapy. The TNF receptor
(TNFR) gene, which is the basis for Immunex's Enbrel product for the treatment
of rheumatoid arthritis, was included in that license. We believe that the
characteristics of AAV vectors make them well suited for delivery of genes to
joints. We are in the process of conducting preclinical experiments designed
to demonstrate the potential of delivering the TNFR gene to joints using AAV
vectors to provide sustained, localized production of the TNFR protein. We
envision an AAV-TNFR product as an attractive alternative to systemic TNFR
protein therapy in patients susceptible to infection or with disease symptoms
limited to one or several joints.

Cardiovascular Disease

   We are collaborating with Collateral Therapeutics, Inc. to assess the
feasibility of an AAV-based product for the delivery of therapeutic genes to
the heart. Collateral has rights to a gene known as AC6, which it believes may
be useful in the treatment of congestive heart failure. Collateral is testing
AAV vectors in animal models to determine the feasibility of delivering AC6
with an AAV vector. If these preclinical tests are successful, we may
collaborate with Collateral to develop an AAV-AC6 gene therapy product.

Acquired Immune Deficiency Syndrome (AIDS)

   We are collaborating with the International AIDS Vaccine Initiative and
Children's Hospital in Columbus, Ohio to develop a vaccine to prevent AIDS.
The vaccine will utilize our AAV vectors to deliver HIV genes with the goal of
eliciting a protective immune response against the virus. The collaboration
will extend for a period of up to three years, beginning in March 2000, and
will include development, preclinical and Phase I clinical studies. We have
the right to commercialize in industrialized countries any vaccine product
that may result from this development collaboration. We also have the option
to manufacture the vaccine for non-industrialized nations.

Core Technologies

   We have assembled a broad range of core technologies that we believe will
allow us to address a number of different diseases. We believe that the three
different vector technologies on which our systems are based, AAV, synthetic
and retroviral, will give us the flexibility to develop gene therapies for a
broader range of diseases than we could develop using any single gene delivery
system. In the area of cell therapy, we believe that our technology and
expertise in isolating and multiplying CTLs could lead to development of a
series of immunotherapies to treat infectious diseases and cancer.

Gene Therapy

   Overview. Gene therapy is an approach to the treatment and prevention of
genetic and acquired diseases that involves inserting genetic information into
target cells to produce specific proteins needed to correct or modulate
disease conditions. Proteins are the fundamental components of all living
cells and are essential to cellular structure, growth and function. Cells
produce proteins from a set of genetic instructions encoded in DNA, which
contains all the information necessary to control cellular biological
processes. DNA is organized into segments called genes, with each gene
containing the information required to express, or produce, a specific
protein.

   An alteration in the function of, or absence of, specific genes causes
certain diseases, including inherited diseases such as cystic fibrosis and
certain types of cancer. Gene therapy may be used to treat these diseases by
replacing a missing or defective gene to facilitate the normal protein
production capabilities of cells. In addition, gene therapy may be used to
enable cells to perform additional roles in the body, such as enhancing the
function of the immune system to fight infectious diseases or cancer. Gene
therapy may also be used to inhibit production of undesirable proteins or
viruses within cells that cause disease.

                                       8

   A key factor in the progress of gene therapy has been the development of
safe and efficient methods of transferring genes into cells. For transfer into
cells, the gene is incorporated into a delivery system called a vector, which
may be derived from either viral or synthetic systems. The most common gene
delivery approach to date relies on viral gene transfer, whereby modified
viruses are used to transfer the desired genetic material into host cells. The
process of gene transfer can be accomplished ex vivo (outside the body),
whereby doctors remove cells from the patient, genetically modify the cells
and then reinfuse them into the patient, or in vivo (inside the body), whereby
vectors are introduced directly into the patient's body.

   The use of viruses takes advantage of their natural ability to introduce
genes into host cells and use the host's metabolic machinery to produce
proteins essential for the survival and function of the virus. In gene therapy
applications, viruses are genetically modified to contain the desired genes
and to inhibit the ability of the virus to reproduce. Successful viral gene
transfer for diseases requiring long-term gene expression involves a number of
essential technical requirements, including the ability of the vector to carry
the desired genes, to transfer the genes into a sufficient number of target
cells and to enable the delivered genes to persist in the host cell. A number
of different viral vectors, including AAV and retroviral vectors, are being
used for potential gene therapy applications requiring long-term gene
expression.

   Current synthetic vector systems generally consist of DNA incorporating the
desired gene, combined with various compounds aimed at enabling the DNA to be
taken up by the host cell. These in vivo gene delivery approaches include:

  .  encapsulating genes into lipid carriers such as liposomes, which
     facilitate the entry of DNA into cells;

  .  complexing negatively charged DNA with positively charged cationic
     lipids;

  .  injecting pure plasmid or naked DNA in an aqueous solution; and

  .  directing DNA to receptors on target cells by combining the gene with
     proteins that bind to the receptors.

   AAV Vectors. Together with our scientific collaborators, we have developed
significant expertise in the design and use of AAV vectors in gene therapy. We
believe that AAV vectors are particularly well suited for the treatment of a
number of diseases because:

  .  AAV has never been associated with causing any human disease;

  .  AAV vectors contain no viral genes that could produce unwanted cellular
     immune responses leading to side effects or reduced efficacy;

  .  AAV vectors can introduce genes into nondividing or slowly dividing
     cells;

  .  AAV vectors can persist in the host cell to provide relatively long-term
     gene expression; and

  .  AAV vectors can be manufactured using methods utilized in the
     manufacture of other biopharmaceutical products.

   We are building a proprietary position in AAV through our development of or
acquisition of exclusive rights to inventions that:

  .  provide important enhancements to AAV vectors;

  .  demonstrate novel approaches to the use of AAV vectors for gene therapy;
     and

  .  establish new and improved methods for large-scale production of AAV
     vectors.

   In addition to our tgAAV-CF clinical development program, we are conducting
preclinical experiments to assess the potential for delivery of genes to other
target cells using AAV vectors. Currently, we are evaluating the use of AAV
vectors in cells of the cardiovascular system, joints and the liver. As
resources become available to do so, we intend to examine, both internally and
through academic collaborators, the use of AAV vectors in additional cell
types.

                                       9
<PAGE>

   Synthetic Vectors. We have exclusive rights to a significant body of
synthetic gene delivery technology based on cationic lipids. These synthetic
vectors are formulated by mixing negatively charged DNA with positively
charged cationic lipids, which promote uptake of genes by cells. These vectors
appear to be safe and they can be used in vivo as well as ex vivo. We believe
that synthetic vectors have several characteristics that make them
particularly well suited for the treatment of certain diseases, including:

  .  the ability to target a specific cell type;

  .  the relative ease of manufacture; and

  .  the ability to transfer relatively large segments of DNA.

   We are working with Dr. Leaf Huang of the University of Pittsburgh to
develop a series of synthetic delivery systems based on his discoveries. Dr.
Huang's original DC-Chol system is used in our potential tgDCC-E1A cancer
product. We have an exclusive license to an issued U.S. patent on DC-Chol for
the treatment of cancer and certain other diseases. Also, we have obtained
from the University of Pittsburgh broad licenses to a series of Dr. Huang's
more recent discoveries in this area. In one of these discoveries, which we
call LPD, DNA is condensed and combined with cationic lipids to generate
particles of defined size that have significantly enhanced gene transfer
efficiency and stability in the bloodstream. We therefore believe that LPD may
be useful for delivery of genes by intravenous administration.

   Enhanced Vectors. In July 1999 we began a collaborative effort with Elan
Pharmaceutical Technologies, a division of Elan Corporation plc, to focus on
developing enhanced gene delivery systems. We established a joint venture with
Elan, Emerald Gene Systems, Ltd., to focus on combining our AAV and synthetic
gene delivery technologies with Elan's drug delivery technologies. Elan's
contributed technologies include targeting ligands, permeation enhancers and
polymers. We plan to develop enhanced gene delivery systems that can be
systemically or orally administered and that will target the desired cells
within the body.

   Retroviral Vectors. We believe that retroviral vectors may be well suited
for ex vivo genetic modification of rapidly dividing cells, such as T cells
and stem cells. We have a strong position in retroviral gene delivery
technology through our relationship with Dr. A. Dusty Miller, a leader in the
development of packaging cell lines for retroviral vectors. One of Dr.
Miller's inventions in this area is an improved retroviral vector packaging
cell line called PG13, which we have licensed exclusively from the Fred
Hutchinson Center Research Center. Our research has shown that vectors
produced in this cell line have improved efficiency for ex vivo transfer of
genes to human T cells and stem cells.

Cell Therapy

   Overview. The immune system is the body's major defense mechanism against
disease. It functions through a complex interplay of components that allow the
body to detect foreign agents and defend against infections and diseases. The
immune system recognizes parts of proteins called antigens that are present on
the surface of diseased cells but are not present on normal cells. The immune
response to an antigen involves the integrated action of various classes of
white blood cells, including lymphocytes. There are two major classes of
lymphocytes, B cells and T cells.

   T cells direct cell-mediated immunity by recognizing antigens on diseased
cells. The two main classes of T cells are CD4 cells and CD8 cells. In
general, CD8 cells are CTLs that recognize, contact and kill the diseased
cells. CD4 cells are primarily helper cells that coordinate the function of
other immune cells, including CTLs, by secreting growth factors known as
cytokines. CTLs are disease-specific: they individually recognize and bind
only to a single, specific antigen. Only in the presence of CD4 helper cells,
furthermore, do these specific CTLs proliferate to produce the large
population of antigen-specific CTLs required to elicit an effective immune
response.

   In some diseases, the immune system fails to mount or maintain an effective
immune response. For infectious diseases and cancer, it is believed that this
failure may be associated with an inadequate CTL response.

                                      10
<PAGE>

For example, HIV infects and kills CD4 cells, which leads to subsequent loss
of CTL function and therefore to destruction of the immune system by the
virus.

   Targeted CTLs. We have developed a highly targeted form of cell therapy,
with which we intend to produce a disease-specific immune response through the
infusion of large numbers of antigen-specific CTLs. In our Targeted CTL
program, antigen-specific CTLs are isolated from a small sample of the
patient's blood, multiplied to large numbers ex vivo and then reinfused into
the patient. In essence, these Targeted CTLs are intended to amplify the
natural disease-fighting function of the immune system relating to specific
infected or cancerous cells.

   We believe that our Targeted CTL program represents an improvement over
other approaches to immunotherapy because:

  .  it is based on highly potent, cloned, antigen-specific CTLs;

  .  virtually all of the reinfused CTLs target the specific diseased cells;
     and

  .  side effects may be reduced due to the uniformity and consistency of the
     reinfused cells.

   Our focus on Targeted CTLs originated from research conducted by Drs.
Philip Greenberg and Stanley Riddell, collaborators at the Fred Hutchinson
Cancer Research Center. These researchers conducted a Phase I clinical trial
to evaluate the use of cytomegalovirus (CMV) -specific CTLs to provide an
immune response against CMV in bone marrow transplant patients. This trial
represented the first use of cloned, antigen-specific CTLs. None of the 14
patients receiving the CTLs developed CMV viremia or disease. Dr. Riddell is
now conducting a Phase II clinical trial to follow up on the promising results
observed in Phase I. Other work by Drs. Greenberg and Riddell has shown,
moreover, that Targeted CTLs may be useful in treating HIV infection.

   In 1998, we completed a preclinical study in which we administered Targeted
CTLs to chimpanzees chronically infected with hepatitis B virus (HBV). The
objective of the study was to establish safety of the therapy and,
potentially, obtain proof of concept that HBV-specific Targeted CTLs could be
promising as a treatment for humans infected with HBV. The preliminary results
of the study, which we presented in August 1998, indicated that the therapy
was safe and that there were trends toward efficacy, evidenced by a temporary
drop in viral burden, increased levels of liver enzymes and improvement in
liver condition. This study has given us additional reason to believe that
Targeted CTLs have potential to treat viral diseases.

   Rapid Expansion Method. The Targeted CTL program is made possible by our
proprietary rapid expansion method, or REM, which we use to rapidly grow CTLs
for infusion into the patient. We believe that REM represents a significant
improvement over other methods of growing T cell clones. Using REM, CTL clones
can be multiplied over a thousand-fold in less than two weeks. We can grow
billions of CTLs from individual cloned cells over several weeks, while
preserving the cells' disease-fighting capabilities. We have seen consistent
results from REM both with CD8 and CD4 T cells. Furthermore, we have shown
that REM is effective for growing Targeted CTLs for a number of viral diseases
and cancers, such as HIV, CMV, HBV, malignant melanoma and prostate tumor
peptides. We have filed patent applications relating to the original REM
process and to subsequent process improvements on a worldwide basis. Since
1998 we have received one U.S. patent in this area.

Research and Development Collaborations

Celltech Group plc/Medeva PLC

   In November 1998, we entered into agreements with Medeva Pharmaceuticals,
Inc. (Medeva), a subsidiary of Medeva PLC to develop and commercialize tgAAV-
CF, our potential gene therapy product for the treatment of cystic fibrosis.
Medeva committed to provide up to three years of funding (up to $5 million per
year) to support tgAAV-CF development and commercialization activities,
including:

  .  scale-up and validation of manufacturing processes;

  .  development and validation of analytical methods;

  .  conduct of Phase I clinical trials; and

  .  other activities in support of product testing and commercialization.

   In addition to development and clinical support, Medeva agreed to pay the
costs of Phase II and subsequent clinical trials of the product. While we may
manage Phase II clinical trials in the United States, Medeva was assigned the
responsibility for conducting all other trials and securing worldwide
registration of tgAAV-CF. Under the terms of the tgAAV-CF agreements, we
granted Medeva an exclusive worldwide license to sell tgAAV-CF, but we
retained responsibility for manufacturing and supplying bulk tgAAV-CF product
to support clinical trials and product commercialization. Medeva agreed to
loan us $2 million to partially fund the construction of a pilot-scale tgAAV-
CF manufacturing facility. Medeva also agreed to loan us, under certain
conditions, up to an additional $10 million toward building a GMP
manufacturing facility for higher-volume production of tgAAV-CF.

   In January 2000, Medeva merged with Celltech/Chiroscience to become part of
Celltech Group plc. Celltech has assumed Medeva's rights and responsibilities
under our agreements.

   Assuming successful commercialization of the tgAAV-CF product, we could
receive a total of up to $54 million in license fees, development funding,
milestone payments, loans and equity investments connected with the
Medeva/Celltech tgAAV-CF agreements. Under a long-term supply agreement we
would also receive proceeds from sales of tgAAV-CF, assuming successful
commercialization, based upon a pricing formula intended to provide us with a
significant percentage of Celltech's net revenue from product sales. The
research and development funding agreement is effective through October 1,
2001, with options to extend the term if both parties agree. The long-term
supply agreement is effective for the term of the patents covering tgAAV-CF.
Celltech may terminate our tgAAV-CF agreements at will with 180 days notice.
Should Celltech exercise its termination right, all rights related to tgAAV-CF
would return to us.

Emerald Gene Systems, Ltd. and Elan Corporation, plc

   In July 1999, we formed a joint venture with Elan International Services,
Ltd., a wholly owned subsidiary of Elan Corporation plc, named Emerald Gene
Systems, Ltd. The joint venture is based in Bermuda and is owned 80.1% by
Targeted Genetics and 19.9% by Elan. Emerald's purpose is to develop enhanced
gene delivery systems based on a combination of our gene delivery technologies
and Elan's drug delivery technologies. Emerald's research and development
program will be Elan's exclusive effort in the field of gene delivery and our
exclusive effort in the combination of our technologies with drug delivery
technologies. Generally, Emerald's research and development will be conducted
under contract by Elan and Targeted Genetics and Emerald will reimburse each
company for the costs of the research and development plus a profit
percentage. Elan and Targeted Genetics will fund the expenses of Emerald in
proportion to their ownership interests.

   As part of our agreements related to Emerald, Elan has provided funding to
us as follows:

  .  a $5 million purchase of our common stock at the signing the agreements;
     and


                                      12
<PAGE>

  .  a $12 million purchase of convertible exchangeable preferred stock at
     the closing of the agreements, the proceeds of which we used to make our
     initial investment in Emerald.

   Elan has also agreed to provide additional funding as follows:

  .  an additional $5 million purchase of our common stock one year from the
     date of our agreements; and

  .  a $12 million line of credit under a convertible note to fund our
     ongoing investment in Emerald.

   At Elan's option, the convertible exchangeable preferred stock can be
converted into common stock of Targeted Genetics or exchanged for an
additional 30.1% ownership in Emerald, which would result in 50/50 ownership
of Emerald.

Alkermes, Inc.

   In June 1999, we entered into a strategic alliance with Alkermes, Inc. in
which we received exclusive rights to an important issued patent and other
pending patent applications related to AAV vector manufacturing. We believe
that the issued patent broadly covers a manufacturing method that is key to
making AAV-based products in a commercially viable, cost-effective manner.
Under the terms of our agreement, we issued to Alkermes 500,000 shares of
common stock and warrants to purchase two million additional shares of common
stock at significant premiums to market price at the time of the transaction.
Alkermes will also receive milestone payments and royalties on products
manufactured using the licensed patents

Relationship with Immunex Corporation

   Targeted Genetics was formed in 1989 as a subsidiary of Immunex, a
biopharmaceutical company developing recombinant proteins as therapeutics. In
February 1992, we spun off as a separate company from Immunex and entered into
a technology license agreement with Immunex. In exchange for shares of our
preferred stock, which were converted into 1,920,000 shares of common stock at
the time of our initial public offering, Immunex granted us a worldwide,
exclusive field-of-use license for certain Immunex proprietary technology
specifically applicable to our gene therapy business. This technology relates
to gene identification and cloning, panels of retroviral vectors, packaging
cell technology, recombinant cytokines, DNA constructs, cell lines,
promoter/enhancer elements and immunological assays. In addition, the
agreement required Immunex to disclose to us, until February 1999, information
concerning improvements discovered or developed by Immunex relating to the
transferred technology such as new techniques, biological materials,
inventions, or developments. We have the option to acquire a nonexclusive,
worldwide, fully paid, royalty-free license and, in some cases, an opportunity
to negotiate the conversion of a nonexclusive license into an exclusive
license, to these improvements. Immunex currently owns approximately 7% of our
outstanding common stock.

Patents and Proprietary Rights

   Patents and licenses are important to our business. Our policy is to file
patent applications to protect technology, inventions and improvements to
inventions that we consider important to the development of our business. We
also rely on trade secrets, know-how, continuing technological innovations and
licensing opportunities to develop and maintain our competitive position. To
date, we have filed or exclusively licensed 107 patent applications relating
to our product and technology development programs with the United States
Patent and Trademark Office (USPTO), as well as foreign counterparts of some
of these applications in Europe, Japan and certain other countries. Of these
patent applications, 29 patents have been issued or allowed by the USPTO.

   In addition to the intellectual property that we own or have exclusively
licensed, we have licensed several issued and pending patents on a
nonexclusive basis. Among these are the two key patents that relate to the use
of AAV vectors for gene therapy licensed from the National Institutes of
Health (NIH) and the University of Florida Research Foundation. In addition,
we have acquired nonexclusive rights to the CFTR gene being delivered in our
tgAAV-CF product.

                                      13
<PAGE>

   The patent positions of pharmaceutical and biotechnology firms, including
our patent positions, are uncertain and involve complex legal and factual
questions for which important legal principles are largely unresolved,
particularly with regard to human therapeutic uses. The coverage claimed in a
patent application may be significantly reduced before a patent is issued.
Consequently, we do not know whether any patent applications will result in
the issuance of patents or, if any patents are issued, whether the patents
will be subjected to further proceedings limiting their scope, whether they
will provide significant proprietary protection or whether they will be
circumvented or invalidated. Since patent applications in the United States
are maintained in secrecy until patents issue and patent applications in other
countries generally are not published until more than 18 months after they are
filed, and since publication of discoveries in scientific or patent literature
often lags behind actual discoveries, we cannot be sure that we or any
licensor were the first creator of inventions covered by pending patent
applications or that we or the licensor were the first to file patent
applications for these inventions.

   We are currently indirectly involved in a patent interference proceeding
declared by the USPTO to determine priority of invention relating to the
nonexclusively licensed CFTR gene delivered in our tgAAV-CF product candidate.
As a nonexclusive licensee of the CFTR gene, we do not expect to directly
participate in the CFTR gene interference proceeding. If the eventual outcome
of the CFTR interference proceeding is unfavorable to our licensor, we may
have to obtain a license from the prevailing party in order to proceed with
development of tgAAV-CF. Costs associated with obtaining a license may be
substantial and could include ongoing royalties in excess of those we
currently pay under our existing CFTR gene license. Any license required in
this circumstance may not be available to us on acceptable terms, if at all.
Although we do not foresee material expenditures related to interference
proceedings, these proceedings could result in substantial financial costs to
us, even if the eventual outcome were favorable to us. Our patents, if issued,
may not be held valid or enforceable by a court and a competitor's technology
or product may not be found to infringe these patents. Litigation, which could
result in substantial cost to us, may be necessary to enforce our patents or
to determine the scope and validity of other parties' proprietary rights. If
the outcome of litigation were adverse, our business could be adversely
affected. We are unable to predict how courts will resolve any future issues
relating to the validity and scope of our patents, should they be challenged.

   A number of pharmaceutical and biotechnology companies and research and
academic institutions have developed technologies, filed patent applications
or received patents on various technologies that may be related to our
business. Some of these technologies, applications or patents may conflict
with our technologies or patent applications. This conflict could limit the
scope of any patents that we might be able to obtain or result in denial of
our patent applications. In addition, if patents that cover our activities are
issued to other companies, we may be required to either obtain a license under
those patents or to develop or obtain alternative technology. A license may
not be available on acceptable terms, if at all, and we may not be able to
develop or obtain alternative technology.

   As the biotechnology industry expands and more patents are issued the risk
increases that our processes and potential products may give rise to claims
that they infringe the patents of others. These other parties could bring
legal actions against us claiming damages and seeking to stop clinical
testing, manufacturing and marketing of the affected product or use of the
affected process. Litigation may be necessary to enforce patents issued to us,
to protect trade secrets or know-how owned by us or to determine the
enforceability, scope and validity of proprietary rights of others. This type
of litigation regardless of its merit, could result in substantial expense to
us and significantly divert the efforts of our technical and management
personnel. An adverse outcome could adversely affect our business. In addition
to any potential liability for damages, we could be required to obtain a
license to continue to manufacture or market the affected product or use the
affected process. Costs associated with any required license could be
substantial and could include ongoing royalties. Any license required under
any infringed patent may not be available to us on acceptable terms, if at
all.

   In addition to patent protection, we rely upon trade secret protection for
our confidential and proprietary information. Other parties may independently
develop substantially equivalent proprietary information and techniques or
gain access to our trade secrets or disclose our technology. To protect our
trade secrets, we require our employees, consultants, scientific advisors and
parties to collaborative agreements to execute confidentiality

                                      14
<PAGE>

agreements. In the case of employees, the agreements also provide that all
inventions resulting from work performed by them while employed by Targeted
Genetics will be our exclusive property. These agreements, however, may not
provide meaningful protection of our trade secrets or adequate remedies in the
event of unauthorized use or disclosure of this information.

Competition

   We are aware of a number of companies and institutions that are developing
or considering the development of potential gene therapy and cell therapy
treatments. These include other gene therapy companies, fully integrated
pharmaceutical companies, universities, research institutions, governmental
agencies and other healthcare providers. In addition, our potential products
will compete with existing pharmaceutical products that are based on
established technologies. Many of our competitors have substantially more
financial and other resources, larger research and development staffs and more
experience and capabilities in researching, developing and testing products in
clinical trials, in obtaining FDA and other regulatory approvals, and in
manufacturing, marketing and distributing products. We also compete with
others to acquire products or technology from research institutions or
universities. In addition, the competitive positions of other companies may be
strengthened through collaborative relationships with large pharmaceutical
companies or academic institutions. Our competitors may develop, obtain patent
protection for, receive FDA and other regulatory approvals for, or
commercialize products more rapidly than we do. If we are successful in
commercializing our products, we will be required to compete with respect to
manufacturing efficiency and marketing capabilities, areas in which we have no
experience. Our competitors may develop new technologies and products that are
available for sale before our potential products or that may be more effective
than our potential products. In addition, our competitors may manufacture and
market their products more successfully than our potential products. These
developments could render our potential products less competitive or obsolete.

Governmental Regulation

   All of our potential products will require regulatory approval by U.S. and
foreign governmental agencies before commercialization in the applicable
countries. Human therapeutic products are subject to rigorous preclinical and
clinical testing and other premarket approval procedures administered by the
FDA and similar authorities in foreign countries. The FDA exercises regulatory
authority over the development, testing, formulation, manufacture, labeling,
storage, record keeping, reporting, quality control, advertising, promotion,
export and sale of our potential products. Similar requirements are imposed by
foreign regulators. In some cases, state requirements may also apply.

   Gene therapy and cell therapy are relatively new technologies and have not
been extensively tested in humans. The regulatory requirements governing gene
and cell therapy products and related clinical procedures are uncertain and
are subject to change. Obtaining approval from the FDA and other regulatory
authorities for a new therapeutic product is likely to take several years, if
approval is ever obtained, and could involve substantial expenditures.
Moreover, ongoing compliance with applicable requirements may also require the
expenditure of substantial resources. We may encounter difficulties or
unanticipated costs in our efforts to secure necessary governmental approvals,
which could delay or prevent the marketing of our products.

   The activities required before a new therapeutic agent may be marketed in
the United States begin with preclinical testing. Preclinical tests include
laboratory evaluation and may require animal studies to assess the product's
potential safety and effectiveness. Animal safety studies must be conducted in
accordance with the FDA's Good Laboratory Practice regulations. The results of
these studies must be submitted to the FDA as part of an Investigational New
Drug application, which must be reviewed and cleared by the FDA before
proposed clinical testing can begin. Clinical trials must be conducted in
accordance with the FDA's Good Clinical Practices regulations under protocols
that detail the objectives of the trial, the parameters to be used to monitor
safety and the efficacy criteria to be evaluated. Each protocol must be
submitted to the FDA as part of the application. The FDA's review or approval
of a study protocol does not necessarily mean that a trial successfully
demonstrating safety or efficacy will result. Further, each clinical trial
must be approved by and conducted under

                                      15
<PAGE>

the auspices of an independent institutional review board at the institution
at which the trial will be conducted. This board will consider, among other
things, ethical factors, the safety of human subjects and the possible
liability of the institution. This review board is also responsible for
continuing oversight of the approved protocols in active trials. A review
board may require changes in a protocol, and the review board may not permit
any given trial to be initiated or completed.

   Clinical trials are typically conducted in three sequential phases,
although the phases may overlap. In Phase I, gene therapy clinical trials
generally involve a small number of patients, who may or may not be afflicted
with a specific disease, to determine the preliminary safety profile. In Phase
II, clinical trials are conducted with larger groups of patients afflicted
with a specific disease in order to establish preliminary effectiveness and
optimal dosages and to obtain additional evidence of safety. In Phase III,
large-scale, multicenter, comparative clinical trials are conducted with
patients afflicted with the target disease in order to provide enough data for
the statistical proof of efficacy and safety required by the FDA and others
for market approval. The FDA receives reports on the progress of each phase of
clinical testing, and it may require the modification, suspension or
termination of clinical trials if patient risk is too high. Because gene
therapy products are a new category of therapeutics, we cannot be certain of
the length of the clinical trial period or the number of patients the FDA will
require to be enrolled in a particular clinical trial in order to establish to
its satisfaction the safety and effectiveness of the products.

   After completion of clinical trials of a product candidate, we are required
to obtain FDA approval to market the product in the U.S. The FDA's legal
authority is defined in the Federal Food, Drug and Cosmetics Act. Our products
are regulated by the Center for Biologics Evaluation and Research. While we
expect this regulatory structure to continue, we also expect the FDA's
regulatory approach to evolve as it increases its scientific knowledge and
experience in gene therapy. Current FDA regulations relating to biologic
therapeutics require us to submit a Biologics License Application to the FDA
before the FDA will permit commercial marketing. This application includes
product development activities, results of preclinical studies and clinical
trials, and detailed manufacturing information. Unless the FDA gives expedited
review status, this stage of the review process takes at least one year. The
FDA may refuse to accept a Biologics License Application if it fails to meet
predetermined requirements.

   The FDA is an agency focused on public health, reviewing all products for
safety and efficacy. Both standards must be met before the FDA grants product
approval. Should the FDA have concerns with respect to product safety and
efficacy, it may delay product review or request additional data. The FDA may
ultimately decide that our license application does not satisfy its criteria
for approval and might require us to do any or all of the following:

  .  modify the scope of our desired product claims;

  .  add warnings or other safety-related information; or

  .  perform additional testing.

   Once approved by the FDA, marketed products are subject to continual FDA
review. Later discovery of previously unknown problems or failure to comply
with applicable regulatory requirements may result in restrictions on
marketing of a product or in its withdrawal from the market, as well as
potential criminal penalties or sanctions.

   The FDA requires that manufacturers of a product comply with current Good
Manufacturing Practices requirements, both as a condition of product approval
and on a continuing basis. In complying with these requirements, we must
expend time, money and effort on a continuing basis in production, record
keeping and quality control. Our manufacturing facilities are subject to
periodic inspections by the FDA to ensure compliance. Failure to pass these
inspections could subject us to possible FDA action, such as the suspension of
manufacturing, seizure of product, withdrawal of approval or other regulatory
sanctions. The FDA could also require us to recall a product.


                                      16
<PAGE>

   In addition to regulations enforced by the FDA, we are also subject to
regulation under the Occupational Safety and Health Act, the Environmental
Protection Act, the Toxic Substances Control Act, the Resource Conservation
and Recovery Act and other federal, state and local regulations. Our research
and development activities involve the controlled use of hazardous materials,
chemicals, biological materials and radioactive compounds. Although we believe
that our safety procedures for handling and disposing of these materials
comply with the standards prescribed by state and federal laws and
regulations, we cannot completely eliminate the risk of accidental
contamination or injury from these materials. In the event of an accident, we
could be held liable for any resulting damages, and any resulting liability
could exceed our financial resources.

Human Resources

   At December 31, 1999, we had 92 full-time-equivalent employees, 72 of which
are directly involved in research and development. Of these employees, 16 have
Ph.D. or M.D. degrees. A significant number of our management and professional
employees have prior experience with other biotechnology or pharmaceutical
companies.

Executive Officers

   The following table lists the executive officers of Targeted Genetics, who
will serve in the capacities noted until their successors are duly appointed
and qualified.

treasurer and assistant secretary of
Receptech. He received his B.A. from the University of Washington.

ITEM 2. PROPERTIES

   We currently occupy approximately 41,000 square feet of laboratory and
office space in two adjoining buildings in Seattle, Washington. The lease on
our primary facility, for approximately 36,000 square feet, extends to April
1, 2004 and has two five-year extension options. The average annual rent
payment for our main facility is approximately $550,000 during the current
five-year lease term. The lease on our adjoining office space, for
approximately 5,000 square feet, expires on March 31, 2004 and has two
additional five-year extension options. The average annual rent payment for
our adjoining office space is approximately $95,000 during the current term of
the lease. In order to continue to grow our AAV vector manufacturing
capability, we expect that we will need to expand our manufacturing operations
to a separate facility. In 1999, we began the process of identifying
alternatives for this expansion. Otherwise, we believe that our current
facilities, together with approximately 2,000 square feet of expansion space
remaining in our primary facility and additional expansion space available in
the adjoining office complex, will be adequate to meet our projected needs for
the next several years. Within that time frame, however, we could be required
to locate alternative facilities, depending on the extent of our company's
growth and development.

ITEM 3. LEGAL PROCEEDINGS

   We are not a party to any legal proceedings.

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

   No matters were submitted to a vote of our security holders during the
fourth quarter of the year ended December 31, 1999.

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

Overview

   We were incorporated in March 1989 as a wholly owned subsidiary of Immunex
Corporation and began operations as an independent company in 1992. Our goal,
both then and now, is to research and develop gene and cell therapy products
to treat acquired and inherited diseases. We now have two lead products in
clinical trials, tgAAV-CF for treating cystic fibrosis and tgDCC-E1A for
treating cancer, and several additional product candidates in preclinical
development. Since our founding, we have focused our efforts on technology and
product development, which we have funded primarily through the sale of equity
securities. In addition, we have endeavored to enter into product
collaborations with other companies as a means to obtain outside funding for
our programs and to broaden the application of our technology platform. We
have completed three collaborations to date that provide ongoing funding of
our research and development programs:

  .  a tgAAV-CF product development collaboration established, with Medeva
     PLC in November 1998;

  .  a gene delivery technology development joint venture with Elan
     Corporation plc, Emerald Gene Systems, Ltd. (Emerald), established in
     July 1999; and

  .  an AAV-based AIDS vaccine development program with the International
     Aids Vaccine Initiative (IAVI), established in February 2000.

   Although our technology appears promising, we do not know whether any
commercially viable products will result from our research and development
efforts. We do not anticipate that we will have any commercial product
revenues for at least the next several years. Through December 31, 1999, our
accumulated losses total approximately $103.5 million. We expect to generate
substantial additional losses in the future, due primarily to the costs of our
preclinical and clinical development programs, developing our manufacturing
capabilities and preparing our products under development for
commercialization. We may never become a profitable company.

Results of Operations

Revenue

   Our revenue results have fluctuated from year to year and will likely
continue to be volatile as we establish collaborations, complete
collaborations, enter into licensing agreements and recognize varying amounts
of revenue from our research and development activity. We had revenue of $6.8
million for the year ended December 31, 1999. Of this amount, $6.4 million was
generated from our tgAAV-CF collaboration agreements with Medeva. We earned
the remainder from a collaborative agreement with our affiliate, Emerald Gene
Systems, for research and development services in the fourth quarter of the
year. Although our 1998 revenue of $7.5 million was greater than our 1999
revenue, we believe that this does not reflect a meaningful trend because
revenue for 1998 included $6.0 million in fees earned up-front when we
established the Medeva collaboration. Revenue for 1998 also included
approximately $1.2 million earned from Medeva for product development efforts
in the fourth quarter of the year.

   We had revenue of $1.3 million for the year ended December 31, 1997. This
amount included a $1.0 million product milestone payment related to our tgDCC-
E1A cancer product, which we received under a European development
collaboration that has since been terminated. Other revenue in 1997 consisted
of grant funding earned from research grants awarded by the National
Institutes of Health.

   We expect our collaborative agreement revenue to increase in 2000. We
expect to realize significant revenue from our Medeva tgAAV-CF collaboration,
including research and development funding, revenue from the supply of tgAAV-
CF product for clinical trials and, potentially, payments upon the achievement
of important product development milestones. We also expect to receive
increased research and development funding from Emerald. In addition, our IAVI
collaboration should provide a new source of research and development funding.

Operating Expenses

Research and Development

   Research and development expenses increased to $14.3 million for 1999 from
$13.3 million for 1998. The increase for 1999 compared to 1998 reflects
increased expenses related to the tgAAV-CF collaboration and, to a lesser
extent, costs incurred to support the Emerald joint venture. These increases
were partially offset by decreases in tgDCC-E1A development expenses. In 1998,
we had higher expenses related to the development of manufacturing methods for
tgDCC-E1A and paid a $1.0 million milestone payment in common stock at the
start of Phase II clinical trials. Additionally, 1998 results included
severance expenses we incurred when we downsized our operations early that
year.

   Research and development expenses for 1998 remained approximately the same
as research and development expenses for 1997. The tgDCC-E1A manufacturing and
milestone expenses and severance expenses we incurred in 1998 generally offset
higher personnel and patent costs in 1997. We expect research and development
expenses to increase for year 2000 due to increases in staffing in the second
half of 1999 and early 2000 to support the Medeva and Emerald projects and
projected increases in external expenses necessary to support tgDCC-E1A
product development in 2000.

Technology License Fee

   We incurred a noncash expense of $3.2 million in 1999 to acquire a
technology license from Alkermes, Inc. We acquired this license by issuing to
Alkermes 500,000 shares of our common stock and warrants to purchase up to
2,000,000 additional shares. We received from Alkermes an exclusive sub-
license to a patent related to the manufacture of AAV vectors, which we use in
our tgAAV-CF cystic fibrosis program, among others. We valued these securities
at $3.2 million, based on the market value of the common stock exchanged and
using the Black- Scholes model to determine the value of the warrants. We
expensed the entire value assigned to the license. While the technology we
acquired under the exclusive license has promise, we expensed the value of the
securities because this technology is in the early stages of development and
its technological feasibility has not been established. We had no technology
license fee expenses in 1998 or 1997.

                                      21
<PAGE>

General and Administrative

   General and administrative expenses increased to $3.6 million for 1999 from
$3.0 million for 1998. This increase was primarily attributable to increases
in personnel costs, increased business development activity and investor
communications costs related to the formation of the Emerald joint venture.
General and administrative expenses increased to $3.0 million for 1998 from
$2.8 million for 1997. The increase was attributable to legal fees incurred
related to the Medeva transaction and increased investor and public relations
costs. These increases were partially offset by decreases in operating
expenses achieved through our February 1998 reduction in staff.

Other Income and Expense

Equity in Loss of Joint Venture

   We recognized a $12.6 million loss in 1999 from our 80.1% equity share in
the loss of the Emerald joint venture. Emerald's losses for the year ended
December 31, 1999 included a $15.0 million noncash charge for an exclusive
license to Elan's drug delivery technology and $742,000 in losses attributable
to Emerald's research and development activities, which began in the fourth
quarter of the year. We expect to record additional equity in losses of
Emerald in 2000 and for the foreseeable future.

Investment Income

   Income from marketable securities decreased to $426,000 for 1999 from
$440,000 for 1998 and $651,000 for 1997. The decreases in 1999 and 1998
resulted from lower average balances of cash available for investment.

Interest Expense

   Interest expense has decreased over the last three years to $235,000 for
1999 from $265,000 for 1998 and $338,000 for 1997, because of declining
principal balances on our capital leases and installment loans. This expense
related to obligations under capital leases and installment loans we use to
finance purchases of laboratory and computer equipment, furniture and
leasehold improvements. We do not expect decreases in interest expense to
continue, since we plan to continue to finance our asset purchases under
leases or loans. We borrowed $1.0  million under a loan agreement with Medeva
in late 1999, and we may elect to borrow additional amounts from Medeva or
Elan in the future under existing loan commitments.

Year 2000 Issue

   As of December 31, 1999 we completed our Year 2000 readiness evaluation and
compliance efforts. Since December 31, 1999 we have not encountered any Year
2000 compliance problems. Nonetheless, some problems related to year 2000
risks may not appear until several months after January 1, 2000. Year 2000
issues could include problems with third-party products or services that we
use or with which our information systems exchange data. Any problems that are
not identified and corrected successfully and completely could adversely
affect our business. We expect that the cost to fix any year 2000 problems
that may be identified, however, will involve internal labor-hours and will
not be material. The costs of our Year 2000 readiness efforts to date are less
than $100,000.

Impact of New Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities. This new statement, which is effective beginning in
2001, establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. Statement No. 133 requires companies to
recognize all derivatives as either assets or liabilities on the balance sheet
and measure those instruments at fair value. Gains or losses resulting from
changes in the values of those derivatives would be accounted for depending on
the use of the derivative and whether it qualifies for hedge accounting under
the standard. The impact of Statement No. 133 on Targeted Genetics' financial
position and results of operations is not expected to be material.

   In December 1999, the Securities Exchange Commission issued Staff
Accounting Bulletin 101"Revenue Recognition in Financial Statements" which
provides the SEC's views on applying generally accepted accounting principles
to revenue recognition issues. The Company is currently evaluating its revenue
recognition policies and has not yet determined the financial statement impact
of this bulletin.

                                      22
<PAGE>

Liquidity and Capital Resources

   Since our inception, we have financed our capital requirements through the
issuance of equity securities, revenue from collaborations and grants and
proceeds from leases and loans. As of December 31, 1999, we had cash, cash
equivalents and securities available for sale totaling $7.2 million, compared
to $12.0 million as of December 31, 1998. The decrease is attributable to our
use of cash to fund our operating losses and capital expenditures. Capital
expenditures of $1.9 million for 1999 reflected construction of and equipment
for a 100-liter scale AAV vector manufacturing facility within our corporate
headquarters. Our cash outflows were partially offset by cash inflows when we:

  .  issued 2,148,899 shares of our common stock to Elan in connection with
     the Emerald joint venture, providing total proceeds of $5.0 million;

  .  issued 677,392 shares of our common stock to Medeva in connection with
     our tgAAV-CF collaboration, providing total proceeds of $1.5 million;
     and

  .  received loan proceeds of $1.0 million from Medeva in October 1999, to
     partially finance the cost of establishing tgAAV-CF manufacturing
     facilities for the supply of bulk product to be used in Phase III
     clinical trials and for initial commercial launch.

   Although we expect our expenses to continue to increase in 2000, we expect
revenue from Medeva, Emerald and IAVI to increase as well, substantially
offsetting expense increases. We also have contractual commitments for the
following cash resources:

  .  a $5.0 million equity investment by Elan;

  .  funds available under a $12.0 million convertible loan from Elan; and

  .  an additional $1.0 million of proceeds under our loan agreement with
     Medeva.

   In March 2000, we entered into a definitive agreement to sell 2,164,285
shares of newly issued common stock in a private placement. This transaction
added approximately $28 million to our cash position.

   Our business strategy includes entering into additional collaborative
relationships with corporate partners to generate license fees, milestone
payments, research and development funding and, potentially, equity
investments, all of which would be used to fund our ongoing operations. We may
not be successful in establishing any additional collaborative relationships
or in maintaining our existing ones. Over the long term, regardless of our
partnering success, we expect that we will need to raise substantial
additional funds to continue developing and commercializing our products.

Factors Affecting Our Operating Results, Our Business and Our Stock Price

   In addition to the other information contained in this annual report, you
should read and consider the following risk factors. If any of these risks
actually occur, our business, financial condition or operating results could
be adversely affected and the trading price of our stock could decline.

If we are unable to secure financing on terms acceptable to us for future
capital needs, we will be unable to fund continuing operations.

   Developing and commercializing our potential products will require
substantial additional financial resources. Because we cannot expect
internally generated cash flow to fund development and commercialization of
our products, we will look to outside sources for funding. These sources could
involve one or more of the following types of transactions:

  .  technology partnerships;

  .  technology sales;

  .  technology licenses;

  .  issuing debt; or

  .  equity arrangements.


                                      23
<PAGE>

   If we cannot obtain additional financing when needed or on acceptable
terms, we will be unable to fund continuing operations. In addition, if we
raise additional funds by issuing equity securities, our shareholders will
likely experience significant dilution of their ownership interest.

We have a history of losses and may never become profitable, which could
result in a decline in the value of our common stock and a loss of your
investment.

   We have generated small amounts of revenue and incurred significant net
losses since we began business. As of December 31, 1999, we have incurred
losses totaling $103.5 million. We expect to continue to incur substantial
additional losses in the future, due primarily to the following factors:

  .  all of our products are in a testing phase and have not received
     regulatory approval; and

  .  we will likely spend significant amounts on operating expenses.

   We may never generate profits, and if we do become profitable, we may be
unable to sustain or increase profitability on a quarterly or annual basis. As
a result, the trading price of our stock could decline and you could lose all
or part of your investment.

If our clinical trials are unsuccessful or we do not receive regulatory
approval for our products, which are in the early stage of product
development, we may be unable to generate sufficient revenues to maintain our
business.

   We do not yet have products in the commercial markets. All of our potential
products, including tgAAV-CF, our cystic fibrosis product candidate, and
tgDCC-E1A, our cancer product candidate, are in research and development or in
early-stage clinical trials. We cannot apply for regulatory approval of our
potential products until we have performed additional research and development
and testing. Our clinical trials may not demonstrate the safety and efficacy
of our potential products, and we may encounter unacceptable side effects or
other problems in the clinical trials. Should this occur, we may have to delay
or discontinue development of the potential product that causes the problem.
After a successful clinical trial, we cannot market products in the United
States until we receive regulatory approval. If we are unable to gain
regulatory approval of our products after successful clinical trials and then
commercialize and sell those products, we may be unable to introduce and sell
a quantity of products sufficient to maintain our business or secure
additional financing to fund our operations.

Delays or unexpected costs in obtaining approval of our products or complying
with governmental regulatory requirements could decrease our ability to
generate revenue and make funding our operations more difficult.

   The regulatory process in the gene and cell therapy industry is costly,
time consuming and subject to unpredictable delays. Accordingly, we cannot
predict with any certainty how long it will take or how much it will cost to
obtain regulatory approvals for clinical trials or for manufacturing or
marketing our potential products. Delays in bringing a potential product to
market or unexpected costs in obtaining regulatory approval could decrease our
ability to generate revenue and make it more difficult to obtain additional
financing necessary to fund our operations. In addition, all manufacturing
operations are subject on an ongoing basis to the current Good Manufacturing
Practices requirement of the Food and Drug Administration. While we currently
anticipate that we will be able to manufacture product that meets this
requirement, we may be unable to attain or maintain compliance with current or
future Good Manufacturing Practices requirements. If we discover previously
unknown problems after we receive regulatory approval of a potential product
or fail to comply with applicable regulatory requirements, we may suffer
restrictions on our ability to market the product, including mandatory
withdrawal of the product from the market. This, or an unexpected increase in
the cost of compliance, could decrease our ability to generate revenue.

Failure to recruit patients could delay or prevent clinical trials of our
potential products, which could cause a delay or inability to introduce
products to market and a resulting decrease in our ability to generate
revenue.

   Identifying and qualifying patients to participate in testing our potential
products is critical to our near-term success. The timing of our clinical
trials depends on the speed at which we can recruit patients to participate in
testing our products. Delays in recruiting or enrolling patients to test our
products could result in increased costs, delays in advancing our product
development, delays in proving the usefulness of our technology or termination
of the clinical trials altogether. If we are unable to timely introduce
potential products to market after successful clinical trials, our ability to
generate revenue may decrease and we may be unable to secure additional
financing.

We may be unable to adequately protect our proprietary rights, which may limit
our ability to compete effectively.

   Our success depends in part on our ability to protect our proprietary
rights. We own or have licenses to patents on a number of genes, processes,
practices and techniques critical to our present and potential products. If we
fail to obtain and maintain patent protection for our technology, our
competitors may market competing products that threaten our market position.
The failure of our licensors to obtain and maintain patent protection for
technology they license to us could similarly harm our business. Patent
positions in the field of biotechnology are highly uncertain and involve
complex legal, scientific and factual questions. Our patent applications may
not result in issued patents. Even if we secure a patent, the patent may not
afford adequate protection against our competitors.

   We also rely on unpatented proprietary technology. Because this technology
does not benefit from the protection of patents, we may be unable to
meaningfully protect this proprietary technology from unauthorized use or
misappropriation by a third party.

Intellectual property claims and litigation could subject us to significant
liability for damages and invalidation of our proprietary rights.

   As the biotechnology industry expands, the risk increases that other
companies may claim that our processes and potential products infringe on
their patents. Defending these claims would be costly and would likely divert
management's attention and resources away from our operations. If we infringe
on another company's patented processes or technology, we may have to pay
damages or obtain a license in order to continue manufacturing or marketing
the affected product or using the affected process. We may be unable to obtain
a license on acceptable terms.

   Our potential tgAAV-CF product uses our proprietary AAV delivery technology
to deliver a normal copy of a CFTR gene to which we have rights under a
nonexclusive license. The United States Patent and Trademark Office has
declared an interference proceeding to determine the priority of invention of
this gene. While we do not expect to directly participate in the CFTR gene
interference proceedings, we have an interest in the outcome. If the eventual
outcome does not favor our licensor, we would have to secure a license to the
CFTR gene from the prevailing party to continue with development of tgAAV-CF.
The costs of licensing the CFTR gene could be substantial and could include
royalties greater than those we currently pay. If we cannot secure this
license on acceptable terms and on a timely basis, we may be unable to develop
or deliver our potential tgAAV-CF product, which could result in decreased
ability to generate revenue and difficulty in obtaining additional financing
to fund our operations.

If we or our business partners are unable to successfully market and
distribute our products, our business will fail.

   We have no experience in sales and marketing. To market any products that
may result from our development programs, we will need to develop marketing
and sales capabilities, either on our own or with others. We intend to enter
into collaborations with corporate partners to utilize the mature marketing
and

                                      25
<PAGE>

distribution capabilities of our partners. While we believe that these
collaborative partners will be motivated to market and distribute our
potential products, our current and potential future partners may not commit
sufficient resources to commercializing our technology on a timely basis.
Furthermore, our present or future collaborators may pursue the development or
marketing of competing products. If our business partners do not successfully
market and distribute our products and we are unable to develop sufficient
marketing and distribution capabilities on our own, our business will fail.

The intense competition and rapid technological change in our market may
result in pricing pressures and failure of our products to achieve market
acceptance.

   We presently face competition from other companies developing gene and cell
therapy technologies and from companies using more traditional approaches to
treating human diseases. Most of our competitors have substantially more
experience and financial and infrastructure resources than we do in the
following areas:

  .  Research and development;

  .  Clinical trials;

  .  Obtaining FDA and other regulatory approvals;

  .  Manufacturing; and

  .  Marketing and distribution.

   Consequently, our competitors may be able to commercialize new products
more rapidly than we do, or manufacture and market competitive products more
successfully than we do. This could result in pricing pressures or the failure
of our products to achieve market acceptance.

   In addition, gene and cell therapy are new and rapidly evolving fields and
are expected to continue to undergo significant and rapid technological
change. Rapid technological development by our competitors could result in our
actual and proposed technologies, products or processes losing market share or
becoming obsolete.

If we do not attract and retain qualified personnel and scientific
collaborators, we will be unable to successfully and timely develop our
potential products and may be unable to generate sufficient revenue to
maintain our business.

   Our future success depends in part on our ability to attract and retain key
employees. We have programs in place to retain personnel, including programs
to create a positive work environment and competitive compensation packages.
Because competition for employees in our field is intense, however, we may be
unable to retain our existing personnel or attract additional qualified
employees. If we experience turnover or difficulties recruiting new employees,
our research and development could be delayed and we could experience
difficulties in generating sufficient revenue to maintain our business.

   Our success also depends on the continued availability of outside
scientific collaborators to perform research and develop processes to advance
and augment our internal research efforts. Competition for collaborators in
gene and cell therapy is intense. If we are unsuccessful in recruiting or
maintaining our relationships with scientific collaborators, we could
experience delays in our research and development or loss of access to
important enabling technology.

Our limited manufacturing capability may limit our ability to successfully
introduce our potential products.

   We currently do not have the capacity to manufacture large-scale clinical
or commercial quantities of our potential products. To do so, we will need to
expand our current facilities and staff or supplement them through the use of
contract providers. We may be unable to obtain or develop the necessary
manufacturing capabilities. If we cannot, we will be unable to introduce
sufficient product to sustain our business.

                                      26

Our use of hazardous materials to develop our products exposes us to liability
risks and the risk of regulatory limitation of our use of these materials,
either of which could reduce our ability to generate revenue and make it more
difficult to fund our operations.

   Our research and development activities involve the controlled use of
hazardous materials. Although we believe that our safety procedures for
handling and disposing of these materials comply with applicable laws and
regulations, we cannot eliminate the risk of accidental contamination or
injury from hazardous materials. If a hazardous material accident occurred, we
would be liable for any resulting damages. This liability could exceed our
financial resources. Additionally, hazardous materials are subject to
regulatory oversight. Accidents unrelated to our operations could cause
federal, state or local regulatory agencies to restrict our access to
hazardous materials needed in our research and development efforts. If our
access to these materials is limited, we could experience delays in our
research and development programs. Paying damages or experiencing delays
caused by restricted access could reduce our ability to generate revenues and
make it more difficult to fund our operations.

The costs of product liability claims and product recalls could exceed the
amount of our insurance, which could significantly harm our results of
operations or our reputation and result in a decline in the value of our
stock.

   Our business activities expose us to the risk of liability claims or
product recalls and any adverse publicity that might result from a liability
claim against us. We currently have only limited amounts of product liability
insurance, and the amounts of claims against us may exceed our insurance
coverage. Product liability insurance is expensive and may not continue to be
available on acceptable terms. A product liability claim not covered by
insurance or in excess of our insurance or a product recall could
significantly harm our financial results or our reputation. Either of these
could result in a decrease in our stock price, and you could lose all or part
of your investment.

Market fluctuations or volatility could cause the market price of our common
stock to decline.

   In recent years the stock market in general and the market for
biotechnology-related companies in particular have experienced extreme price
and volume fluctuations, often unrelated to the operating performances of the
affected companies. Our common stock has experienced, and is likely to
continue to experience, these fluctuations in price, regardless of our
performance. These fluctuations could cause the market price of our common
stock to decline.

ITEM 7A. QUALITATIVE AND QUANTITATIVE DISCLOSURES ABOUT MARKET RISK

   This item discusses our exposure to market risk related to changes in
interest rates, equity prices and foreign currency exchange rates.

Interest Rate Sensitivity

Short-Term Investments

   As of December 31, 1999, we had short-term investments of $3.1 million.
These short-term investments consisted of highly liquid investments with
original maturities at the date of purchase of between 18 months and two
years, with an average maturity of less than one year. These investments are
subject to interest rate risk and will decrease in value if market interest
rates increase.

   We performed a sensitivity analysis on our investment portfolio as of
December 31, 1999. This analysis was based on a modeling technique that
measures the hypothetical market value change that would result from an
increase in market interest rates of 100 or 200 basis points over a six-month
and twelve-month time horizon. The market value changes resulting from a 100
or 200 basis-point increase in short-term treasury security yields were not
material because all of our investments held as of December 31, 1999 mature in
2000.

   Because we expect to hold most of these investments until maturity, we do
not expect the realized value of these investments to be affected to any
significant degree by the effect of a sudden change in market interest rates.
Declines in interest rates over time, however, would reduce our interest
income.

                                      27
<PAGE>

Long Term Obligations

   As of December 31, 1999, we had outstanding long term obligations,
primarily related to capital equipment leases, leasehold improvements and our
loan agreement with Medeva of $3.3 million, at fixed interest rates of up to
14.62%. Because the interest rates on our long term obligations are fixed, a
hypothetical 10 percent decrease in interest rates would not have a material
impact on our financial position. Increases in interest rates could, however,
increase the interest expense associated with any future borrowings. We do not
hedge against interest rate increases.

Market and Credit Risk

   We do not use derivative financial instruments in our investment portfolio
to manage interest rate risk. We do, however, limit our exposure to interest
rate and credit risk by establishing and strictly monitoring clear policies
and guidelines for our fixed income portfolios. At the present time we limit
to one year the maximum average maturity period of securities in our
investment portfolio. Our guidelines also establish credit quality standards,
limits on exposure to duration and credit risk criteria. We do not expect our
exposure to market and credit risk to be material. As of December 31, 1999, we
had a concentration of accounts receivable with one of our collaborators.

Equity Price Risk

   Our equity price risk is limited to the risk inherent in our ownership of
80.1% of Emerald, our joint venture with Elan, and an immaterial equity
interest we have in another biotechnology company. Accordingly, we do not
hedge against equity price changes.

Foreign Currency Exchange Rate Risk

   We realize all of our revenue in dollars and receive substantially all of
our cash from Medeva's U. S.-based operations and Emerald's Bermuda-based
operations. Therefore, we do not believe that we have any significant direct
foreign currency exchange rate risk and we do not hedge against foreign
currency exchange rate changes.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

The Board of Directors and Shareholders
Targeted Genetics Corporation

   We have audited the accompanying balance sheets of Targeted Genetics
Corporation as of December 31, 1999 and 1998, and the related statements of
operations, shareholders' equity, and cash flows for each of the three years
in the period ended December 31, 1999. These financial statements are the
responsibility of the Company's management. Our responsibility is to express
an opinion on these financial statements based on our audits.

   We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on
a test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as 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 Targeted Genetics
Corporation at December 31, 1999 and 1998, and the results of its operations
and its cash flows for each of the three years in the period ended December
31, 1999 in conformity with accounting principles generally accepted in the
United States.

                         NOTES TO FINANCIAL STATEMENTS

1. Nature of Operations

   Targeted Genetics Corporation ("Targeted Genetics" or the "Company") is
developing gene therapy products for the treatment of certain acquired and
inherited diseases. Targeted Genetics was incorporated in the state of
Washington in March 1989. The Company's operations constitute one business
segment.

2. Summary of Significant Accounting Policies

Cash Equivalents

   Targeted Genetics considers as cash equivalents all short-term investments
with a purchased maturity of three months or less that are readily convertible
into cash and have insignificant interest rate risk. Cash equivalents, valued
at cost that approximates market, consist principally of money market accounts
and short-term government obligations. All other investments are reported as
securities available for sale.

Securities Available for Sale

   Securities available for sale consist primarily of corporate debt
securities and U.S. government notes, all of which mature within one year.
Targeted Genetics currently classifies its entire investment portfolio as
securities available for sale. Such securities are stated at market value,
with the unrealized gains and losses included as a component of shareholders'
equity. The cost of debt securities in this category is adjusted for
amortization of premiums and accretion of discounts to maturity, which are
included in investment income. Realized gains and losses and declines in value
judged to be other than temporary on securities available for sale are also
included in investment income. The cost of securities sold is calculated using
the specific identification method.

Fair Value of Financial Instruments

   The carrying amounts of financial instruments such as cash, and cash
equivalents, investments, accounts receivable and accounts payable reasonably
approximate fair value because of the short-term nature of these items. The
Company believes the carrying amounts of the note payable and capital leases
obligations approximate fair value because the interest rates on these
instruments change with, or approximate, market interest rates.

Property, Plant and Equipment

   Property, plant and equipment are stated at cost. Depreciation of furniture
and equipment is provided using the straight-line method over the assets'
estimated useful lives, which range from three to seven years. Furniture and
equipment under capitalized leases are amortized over the life of the lease.
Leasehold improvements are amortized over the life of the improvements or the
term of the lease, whichever is shorter. Amortization of assets recorded under
capital leases is included with depreciation expense.

Stock Compensation

   As permitted by the provisions of Financial Accounting Standards Board
Statement No. 123, Accounting for Stock-Based Compensation, the Company has
elected to follow Accounting Principles Board Opinion No. 25, Accounting for
Stock Issued to Employees, and related interpretations in accounting for its
employee stock option grants and apply the disclosure-only provisions to
account for its stock option plans. The Company does not recognize any
compensation expense related to the plans since all options are granted at
fair market value on the date of grant. Options granted to consultants are
accounted for using the Black-Scholes method prescribed by Statement 123 and
are subject to periodic revaluation over their vesting terms.

                                      34

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


Revenue under Collaborative Agreements

   Revenue under collaborative agreements is recognized according to the terms
of the collaborative agreements. Nonrefundable product license fees that are
not dependent on future performance are recognized as revenue when received.
Up-front signing or licensing fees that are dependent on future performance
are recognized ratably over the period in which the related work is performed.
Milestone revenue is recognized upon the achievement of the related milestone
and when collection is probable. Revenue earned from the performance of
research and development is recognized over the period in which the related
work is performed. Advance payments received in excess of amounts earned are
classified as deferred revenue.

Net Loss Per Share

   Basic net loss per share is computed based upon the weighted average number
of common shares outstanding during the period. The Company's diluted net loss
per share is the same as its basic net loss per share because all stock
options, warrants and other potentially dilutive securities are antidilutive
and are therefore excluded from the calculation of diluted net loss per share.

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 amounts reported in the financial statements and
accompanying notes. Actual results may differ from those estimates.

New Accounting Pronouncements

   In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, Accounting for Derivative Instruments
and Hedging Activities. This new statement, which is effective beginning in
2001, establishes accounting and reporting standards for derivative
instruments, including certain derivative instruments embedded in other
contracts, and for hedging activities. Statement No. 133 requires companies to
recognize all derivatives as either assets or liabilities on the balance sheet
and measure those instruments at fair value. Gains or losses resulting from
changes in the values of those derivatives would be accounted for depending on
the use of the derivative and whether it qualifies for hedge accounting under
the standard. The impact of Statement No. 133 on Targeted Genetics' financial
position and results of operations is not expected to be material.

   In December 1999, the Securities Exchange Commission issued Staff
Accounting Bulletin 101 Revenue Recognition in Financial Statements which
provides the SEC's views on applying generally accepted accounting principles
to revenue recognition issues. The Company is currently evaluating its revenue
recognition policies and has not yet determined the financial statement impact
of this bulletin.

3. Significant Concentrations

   The Company's collaborative agreement with Medeva PLC, provided 87%, 88%
and 0% of revenue in fiscal years ending December 31, 1999, 1998 and 1997,
respectively. See note 8. At December 31, 1999 and 1998, amounts receivable
from Medeva represented 76% and 100%, respectively, of the Company's accounts
receivable balance. The Company does not require collateral or security
related to receivables and has historically had no losses on uncollectible
accounts. Accordingly, no allowance for bad debts has been recorded.

</TABLE>

   Future aggregate principal payments related to long-term obligations are
$1,141,485 in 2000, $606,346 in 2001, $419,129 in 2002, $77,115 in 2003 and
$1,004,307 in 2004.

   The Company has an agreement with Medeva/Celltech under which, subject to
certain circumstances, Medeva/Celltech will loan the Company up to $2.0
million. Loan proceeds are unsecured and are required to be used to partially
finance the cost of establishing tgAAV-CF manufacturing facilities for the
supply of bulk product to be used in Phase III clinical trials and for initial
commercial launch. As of December 31, 1999, the Company has borrowed $1.0
million under the agreement. No amount was borrowed at December 31, 1998.
Interest on borrowings is payable annually in arrears at a rate that is 150
basis points over the one-month LIBOR rate, but not less than 5% nor more than
7% per year. The Company recognized $18,689 of interest expense in 1999.
Principal is due and payable in November 2003, or earlier if the cumulative
net product sales of the Company's cystic fibrosis product equal or exceed
$60.0 million. The loan agreement contains financial covenants including
limits on the Company's ability to declare or pay dividends. The Company can
at its option, and with Medeva's consent, repay the loan with its common stock
at any time during the loan term, at a conversion price equal to the average
closing price of the common stock over a twenty-day period preceding the
repayment date.

7. Shareholders' Equity

Series B Preferred Stock

   In July 1999, Elan International Services, Ltd. purchased $12,015,000 of
the Company's Series B preferred stock in conjunction with the formation of
the Emerald Gene Systems Ltd. ("Emerald") joint venture. See note 13. This
preferred stock bears an annual dividend of 7%, accrued semi-annually and
added to principal. The Series B preferred stock is convertible until July
2005, at Elan's option, into the Company's common stock, at a price of $3.32
per share. As of December 31, 1999 the Company had accrued dividends of
$376,000. Elan's holdings of the Series B preferred stock were convertible
into 3,732,106 shares of the common stock as of December 31, 1999. The Company
would issue 5,740,548 shares of its common stock if Elan were to elect to
convert its preferred stock to shares of common stock as of July 21, 2005, the
expiration of the conversion option. Alternatively, Elan has an option to
exchange the Series B preferred stock and all accumulated dividends for a
30.1% interest in Emerald. This exchange option is exercisable up to six
months after the completion of a research and development program that is
currently anticipated to be 36 to 48 months in length. This exchange right
will terminate if the preferred stock is converted into common stock, unless
the conversion occurs as a result of a liquidation or certain transactions
involving a change of control of the Company.

                  NOTES TO FINANCIAL STATEMENTS--(Continued)


   Should the Company liquidate or wind-down its operations, the agreement
gives Series B preferred shareholders priority over common shareholders with
respect to the assets legally available for distribution to shareholders. The
Series B shareholders' liquidation preference is at par value. The Company has
redemption rights to these shares only in certain instances involving change
of control. Holders of Series B preferred stock are not entitled to vote
together with holders of common stock with respect to election of directors or
other corporate governance matters.

Warrants

   In June 1999, the Company issued warrants to purchase 2,000,000 shares of
its common stock to Alkermes, Inc. These warrants were issued in two tranches
of 1,000,000 shares each. The warrants expire in June 2007 and June 2009 and
are priced at $2.50 and $4.16 per share, respectively. See note 9.

   In 1998, the Company completed a private placement of common stock and
warrants, which resulted in net proceeds of approximately $12.8 million.
Warrants to purchase a total of 4,333,333 shares of common stock were issued
in the transaction, with an exercise price of $2.00 per share and an
expiration of April 2003.

   The Company has outstanding warrants to purchase a total of 126,016 shares
related to equipment financing, consulting and license agreements. These
warrants have a weighted average price of $4.42 per share and expire between
May 2001 and March 2004.

   At December 31, 1999, 6,459,349 shares of common stock were reserved for
all outstanding warrants.

Shareholder Rights Plan

   The Company has adopted a shareholder rights plan, under which it has
distributed a dividend of one right for each outstanding share of common
stock. These rights could cause substantial dilution to certain persons or
groups that attempt to acquire the Company on terms not approved by the
Company's Board of Directors.

Stock Options

   The Company has three stock option plans. Beginning in 1999 the Company
began granting all options from the 1999 Stock Option Plan (the "1999 Plan"),
and discontinued grants from the other two plans. The 1999 Plan provides for
option grants of up to a maximum of 1.5 million shares of common stock to
employees, directors and officers of the Company and consultants, agents,
advisors and independent contractors who provide services to the Company.
Generally, options vest in even quarterly or annual increments over a three-
to five-year period. All options expire ten years from date of grant. As of
December 31, 1999, options to purchase 1,175,125 shares were available for
future grant under the 1999 Plan. The following table summarizes activity
related to the Company's stock option plans:

</TABLE>

   During 1999, options were exercised at prices ranging from $0.55 to $2.25
per share. Options for 1,094,420, 628,785 and 611,465 shares were exercisable
at December 31, 1999, 1998 and 1997, respectively. In 1998, the Company
offered active employees, except executive officers, the opportunity to cancel
previously awarded stock option grants with exercise prices greater than the
current market price of common stock and be granted the same number of new
options at the closing market price on the grant date. Substantially all
eligible employees elected to replace their previously awarded stock option
grants, resulting in the cancellation of options to purchase 531,550 shares at
an average price of $3.77 per share and the issuance of options to purchase
the same number of shares at $1.22 per share. The new options awarded under
this offer vest over a three-year period, 25% upon the date six months after
the grant date, 25% upon the date twelve months after the grant date and 6.25%
at the end of each three-month period thereafter.

   In conformity with the provisions of Statement No. 123, Accounting for
Stock-Based Compensation, the Company has elected to follow the intrinsic
value method allowed under that statement for its stock option plans and
present pro forma disclosures using the fair value accounting approach. Had
compensation costs been recorded, the following amounts would have been
reported:

   The fair value of each option is estimated on the date of grant using the
Black-Scholes multiple-option approach pricing model with the following
weighted average assumptions:

</TABLE>

   The weighted average fair value of options granted during 1999, 1998 and
1997 was $1.94, $1.11 and $2.51 per share, respectively. Compensation expense
included in these pro forma amounts may not be representative of the effects
on pro forma earnings for future years

   As of December 31, 1999, the Company had reserved a total of 13,807,922
shares of common stock for issuance pursuant to conversion of preferred stock
and stock options.

8. Collaborative Agreements

Celltech Group plc Agreement

   In 1998 Targeted Genetics entered into a series of agreements (the "CF
Agreements") with Medeva. In January 2000, Medeva merged with
Celltech/Chiroscience to become part of the Celltech Group Plc. Celltech has
assumed Medeva's rights and responsibilities under our agreements. Targeted
Genetics and Medeva are collaborating to develop on a worldwide basis the
Company's tgAAV-CF gene therapy product for the treatment of cystic fibrosis.
Upon signing the CF Agreements, Targeted Genetics received a license and
technology access fee of $5.0 million and a milestone payment of $1.0 million
related to the start of Phase I clinical trials for the aerosolized version of
the tgAAV-CF product. Medeva agreed to pay up to $5.0 million per year for
three years to fund the Company's tgAAV-CF research and development activities
and certain Phase I clinical trial expenses. In addition, Medeva agreed to pay
the costs of Phase II and subsequent clinical trials of the product. Assuming
successful development and regulatory approval, Celltech will have the
exclusive right to market the product on a worldwide basis. Under a long-term
supply agreement, the Company will manufacture and supply bulk product to
Celltech under a pricing formula constructed to compensate with a fixed
percentage of Celltech's net product sales. The research and development
funding agreement is effective from October 1998 to October 2001, with options
to extend the term if both parties agree. The long-term supply agreement is
effective for the term of the patents covering the Company's tgAAV-CF
technology. Celltech has the option to terminate the CF Agreements at will
with 180 days notice. Should Celltech exercise this right to terminate the CF
Agreements, all rights related to tgAAV-CF technology would return to the
Company. The Company recognized $6.4 million and $7.0 million of revenue under
the CF Agreements in 1999 and 1998.

   Under separate agreements, Medeva agreed to purchase $3.0 million of
Company common stock and, subject to certain provisions, to loan the Company
up to $12.0 million. Medeva purchased $3.0 million of common stock in two
tranches: 750,000 shares of common stock for $1.5 million upon signing of the
stock purchase agreement in 1998 and 677,392 shares of common stock for $1.5
million in 1999. Subject to certain conditions, the Company can draw up to
$2.0 million to partially fund construction of facilities to support Phase III
trials and initial commercialization. At December 31, 1999, the Company has
drawn $1.0 million. See note 6. Under certain conditions, Medeva agreed to
loan us up to an additional $10 million toward building a manufacturing
facility compliant with the FDA's Good Manufacturing Practices guidelines for
higher-volume production of tgAAV-CF. No amounts have been drawn under the
$10.0 million commitment.

Elan Corporation plc

   In July 1999, the Company and Elan formed Emerald, a joint venture to
develop enhanced gene delivery technology and products.

   Elan has agreed to loan the Company up to $12.0 million under a convertible
promissory note agreement to support its share of the joint venture's research
and development costs. The note has a six-year term, accrues interest at 12%
per year. The note and related accrued interest are convertible into the
Company's common stock at conversion prices set at 150% of the average closing
price of the Company's common stock for the 60 trading days ending two
business days before the time the Company draws loan proceeds. The note
agreement includes provisions allowing the Company to convert the debt into
the Company's common stock at the lesser of the current market price or the
conversion price, at its option. As of December 31, 1999, the Company has not
drawn on the note.

   The Company also entered into an agreement with Elan that requires Elan to
purchase up to $10.0 million of the Company's common stock at a premium to
market price. Elan purchased $5.0 million of Targeted Genetics' common stock
in connection with closing of the joint venture transaction, or 2,148,899
shares. At the Company's option, Elan will purchase an additional $5.0 million
of Targeted Genetics common stock in July 2000 at 120% of the market price at
that time.

9. Alkermes License

   On June 9, 1999, the Company entered into an agreement with Alkermes, Inc.
to acquire the exclusive rights to a patent for the manufacture of AAV
vectors. The license to this technology, first developed by Children's
Hospital in Columbus, Ohio, covers the use of cell lines for the manufacture
of AAV vectors and expands a previously acquired limited field license to
these rights. The Company issued 500,000 shares of its common stock and
warrants to purchase a total of up to 2,000,000 additional shares in exchange
for this technology license. See note 7. Under the terms of the license, the
Company is responsible for endeavoring to commercialize the technology.
Additionally, the Company is obligated to make milestone payments as products
using this technology reach clinical trial and regulatory milestones. The
Company is also obligated to pay royalties upon the sale of AAV products or
sub-licensing of the licensed technology. The Company recorded a $3.2 million
non-cash charge with respect to the Alkermes license in its 1999 operating
results, because the underlying technology is not complete and the Company
will have to invest significant resources to develop and prove its commercial
feasibility.

10. Lease Commitments

   The Company leases its research and office facilities under two
noncancellable operating leases that expire beginning March 31, 2004. The
leases may be extended under two additional five-year renewal options at the
then-prevailing fair market value rental rate.

   Rent expense under operating leases for the years ended December 31, 1999,
1998 and 1997 was $587,000, $533,000 and $533,000, respectively.

11. Employee Retirement Plan

   The Company sponsors an employee retirement plan in accordance with Section
401(k) of the Internal Revenue Code. All employees at least 21 years old are
eligible to participate in the plan. Contributions made into the plan are at
the discretion of the board of directors. The Company incurred $90,181, $0,
and $99,426 of expense in 1999, 1998 and 1997, respectively, related to
contributions to the plan.

12. Income Taxes

   At December 31, 1999, the Company had net operating loss carryforwards of
$70.1 million and research and experimental credit carryforwards of $1.8
million. The carryforwards are available to offset future federal income taxes
and begin to expire in 2008. The Company has provided a valuation allowance to
offset the excess of deferred tax assets over the deferred tax liabilities,
due to the uncertainty of realizing the benefits of the net deferred tax
asset. The valuation allowance increased by $3.9 million in 1999 and $2.8
million during 1998.

   Significant components of the Company's deferred tax assets and liabilities
were as follows:

   Utilization of federal income tax carry-forwards is subject to certain
limitations under Section 382 of the Internal Revenue Code. The Company's past
sales and issuances of common stock have resulted in "ownership changes" as
defined under Section 382, that may result in limitations on the future use of
some portion of the net operating loss carryforwards.

13. Joint Venture

   In July 1999, the Company and Elan formed Emerald, a joint venture to
develop enhanced gene delivery technology and products. At the time the joint
venture was formed, Elan purchased $12,015,000 of the Company's Series B
convertible exchangeable preferred stock. See note 7. The preferred stock is
convertible, at Elan's option, into Targeted Genetics common stock or into
shares representing a 30.1% interest in Emerald, increasing Elan's ownership
in Emerald to 50%. Targeted Genetics used the proceeds of the convertible
exchangeable preferred stock sale to purchase its 80.1% interest in Emerald.
Emerald used these proceeds to pay $15.0 million to Elan for a license giving
Emerald exclusive rights to use Elan drug delivery technologies within the
gene delivery field.

   The Company formed Emerald by issuing Emerald preferred and common stock
valued at $15,000,000 to Targeted Genetics and Elan. The Company currently
owns an 80.1% interest in Emerald and Elan owns 19.9% (non-voting). While
Targeted Genetics owns 100% of the voting common shares, Elan and its
subsidiaries have retained significant minority investor rights that are
considered "participating rights" as defined in the Financial Accounting
Standards Board's Emerging Issues Task Force Bulletin 96-16, Investors'
Accounting for an Investee When the Investor Has a Majority of the Voting
Interest but the Minority Shareholder Has Certain Approval or Veto Rights.
Elan's participating rights prevent the Company from exercising control over
Emerald. Accordingly, the Company does not consolidate the financial
statements of Emerald but instead accounts for its investment in Emerald under
the equity method of accounting.

   The condensed financial information of Emerald as of December 31, 1999 and
for the period from July 21, 1999 (date of inception) through December 31,
1999 is as follows:

   Included in the Company's December 31, 1999 balance sheet are a $445,818
receivable from Emerald for services performed by the Company for Emerald and
a payable to Emerald of $594,699 for the Company's 80.1% share of Emerald's
funding requirements as of December 31, 1999. The Company expects to advance
Emerald its share of the required funding and collect the $445,818 Emerald
account receivable during the first quarter of 2000. The Company is required
to provide additional funding to Emerald as needed in relation to its
ownership interest in Emerald.

14. Subsequent Events

   On March 1, 2000, Targeted Genetics announced that it had entered into a
definitive agreement for the placement of 2,164,285 shares of newly issued
common stock that resulted in gross proceeds to the Company of $30.3 million.

                       NOTES TO THE FINANCIAL STATEMENTS

                               December 31, 1999
                     (expressed in United States dollars)

1. Operations

   The company was incorporated July 19, 1999 in Bermuda. The company is owned
by Elan International Services Ltd. ("EIS") a wholly-owned subsidiary of Elan
Corporation plc, and Targeted Genetics Corporation ("TGC"), holding 19.9%
(non-voting shares) and 80.1% of the shares respectively. The primary
objective of the company is to carry on the business of the development,
testing, registration, manufacturing, commercialization, and licensing of
"Products" (as defined in the Subscription, Joint Development and Operating
Agreement ("JDOA") dated July 21, 1999 between EIS, TGC and others). The focus
of the collaborative venture will be to develop the "Products" using the Elan
Intellectual Property, the TGC Intellectual Property and the Emerald
Technology pursuant to the JDOA.

2. Significant accounting policy

   The company follows accounting principles generally accepted in the United
States. Significant accounting policies are as follows:

(a) Research and development costs

   Research costs are charged as an expense of the period in which they are
incurred. Development costs are deferred to future periods if certain criteria
relating to future benefits are satisfied and if the costs do not exceed the
expected future benefits.

(b) Use of estimates

   The preparation of financial statements in accordance with GAAP requires
management to make estimates and assumptions that affect the reported amount
of assets and liabilities and the disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amount of
revenues and expenses during the reporting period. Actual results could differ
significantly from those estimates.

3. Related party transactions

   The following table summarizes the company's related party transactions for
the period:

<TABLE>

                                                                        --------

      Research and development costs
        To companies related through common ownership.................. $277,502
        To shareholders................................................  445,818

repayment.

                                                                       =======
</TABLE>

6. Contributed surplus

   Contributed surplus represents share premium on amounts contributed by
shareholders in addition to their subscription to the issued share capital.

7. Year 2000 Issue (unaudited)

   The Year 2000 Issue arises because many computerized systems use two digits
rather than four to identify a year. Date-sensitive systems may recognize the
year 2000 as 1900 or some other date, resulting in errors when information
using year 2000 dates is processed. In addition, similar problems may arise in
some systems which use certain dates in 1999 to represent something other than
a date.

   Although the change in date has occurred, it is not possible to conclude
that all aspects of the Year 2000 Issue that may effect the entity, including
those related to customers, suppliers, or other third parties, have been fully
resolved.

8. Taxes

   Under current Bermuda law the company is not required to pay any taxes in
Bermuda on either income or capital gains. The company has received an
undertaking from the Minister of Finance in Bermuda that in the event of such
taxes being imposed the company will be exempted from taxation until the year
2016.

                         TARGETED GENETICS CORPORATION

                           INDEMNIFICATION AGREEMENT

     INDEMNIFICATION AGREEMENT, dated as of March 30, 1994, between TARGETED
GENETICS CORPORATION, a Washington corporation (the "Company"), and
_________________, a director and/or officer of the Company (the "Indemnitee").

                                    RECITALS

     A.  Indemnitee is a director and/or officer of the Company and in such
capacity is performing valuable services for the Company.

     B.  The Company and Indemnitee recognize the difficulty in obtaining
directors' and officers' liability insurance, the significant cost of such
insurance and the general reduction in the coverage of such insurance.

     C.  The Company and Indemnitee further recognize the substantial increase
in litigation subjecting directors and officers to expensive litigation risks at
the same time that such liability insurance has been severely limited.

     D.  The shareholders of the Company have adopted bylaws (the "Bylaws")
providing for the indemnification of the directors, officers, agents and
employees of the Company to the full extent permitted by the Business
Corporation Law of Washington (the "Statute").

     E.  The Bylaws and the Statute specifically provide that they are not
exclusive, and thereby contemplate that contracts may be entered into between
the Company and the members of its Board of Directors and its officers with
respect to indemnification of such directors and officers.

     F.  In order to induce Indemnitee to serve, or to continue to serve, as a
director and/or officer of the Company, the Company has agreed to enter into
this Agreement with Indemnitee.

                                   AGREEMENTS

                                                                          Page 2
<PAGE>

     In consideration of the recitals above, the mutual covenants and agreements
herein contained, and Indemnitee's continued service as a director and/or
officer after the date hereof, the parties to this Agreement agree as follows:

1.   Indemnity of Indemnitee

     1.1.   Scope

     The Company agrees to hold harmless and indemnify Indemnitee to the full
extent permitted by law, notwithstanding that such indemnification is not
specifically authorized by this Agreement, the Company's Articles of
Incorporation, the Bylaws, the Statute or otherwise.  In the event of any
change, after the date of this Agreement, in any applicable law, statute or rule
regarding the right of a Washington corporation to indemnify a member of its
board of directors or an officer, such changes, to the extent that they would
expand Indemnitee's rights hereunder, shall be within the purview of
Indemnitee's rights and the Company's obligations hereunder, and, to the extent
that they would narrow Indemnitee's rights hereunder, shall be excluded from
this Agreement; provided, however, that any change that is required by
applicable laws, statutes or rules to be applied to this Agreement shall be so
applied regardless of whether the effect of such change is to narrow
Indemnitee's rights hereunder.

     1.2.   Nonexclusivity

     The indemnification provided by this Agreement shall not be deemed
exclusive of any rights to which Indemnitee may be entitled under the Company's
Articles of Incorporation, the Bylaws, any agreement, any vote of shareholders
or disinterested directors, the Statute, or otherwise, whether as to action in
Indemnitee's official capacity or otherwise.

     1.3.  Included Coverage

     If Indemnitee was or is made a party, or is threatened to be made a party,
to or is otherwise involved (including, without limitation, as a witness) in any
Proceeding (as defined below), the Company shall hold harmless and indemnify
Indemnitee from and against any and all losses, claims, damages, liabilities or
expenses (including attorneys' fees, judgments, fines, ERISA excise taxes or
penalties, amounts paid in settlement and other expenses incurred in connection
with such Proceeding) (collectively, "Damages").

     1.4.  Definition of Proceeding

     For purposes of this Agreement, "Proceeding" shall mean any actual, pending
or threatened action, suit, claim or proceeding, whether civil, criminal,
administrative

                                                                          Page 3
<PAGE>

or investigative and whether formal or informal, in which Indemnitee is, was or
becomes involved by reason of the fact that Indemnitee is or was a director,
officer, employee or agent of the Company or that, being or having been such a
director, officer, employee or agent, Indemnitee is or was serving at the
request of the Company as a director, officer, employee, trustee or agent of
another corporation or of a partnership, joint venture, trust or other
enterprise (collectively a "Related Company"), including service with respect to
an employee benefit plan, whether the basis of such proceeding is alleged action
(or inaction) by Indemnitee in an official capacity as a director, officer,
employee, trustee or agent or in any other capacity while serving as a director,
officer, employee, trustee or agent; provided, however, that, except with
respect to an action to enforce the provisions of this Agreement, "Proceeding"
shall not include any action, suit, claim or proceeding instituted by or at the
direction of Indemnitee unless such action, suit, claim or proceeding is or was
authorized by the Company's Board of Directors.

     1.5.  Determination of Entitlement

     In the event that a determination of Indemnitee's entitlement to
indemnification is required pursuant to Section 23B.08.550 of the Statute or a
successor statute or pursuant to other applicable law, the appropriate decision-
maker shall make such determination; provided, however, that Indemnitee shall
initially be presumed in all cases to be entitled to indemnification, that
Indemnitee may establish a conclusive presumption of any fact necessary to such
a determination by delivering to the Company a declaration made under penalty of
perjury that such fact is true and that, unless the Company shall deliver to
Indemnitee written notice of a determination that Indemnitee is not entitled to
indemnification within twenty (20) days after the Company's receipt of
Indemnitee's initial written request for indemnification, such determination
shall conclusively be deemed to have been made in favor of the Company's
provision of indemnification and Company hereby agrees not to assert otherwise.

     1.6.  Survival

     The indemnification provided under this Agreement shall apply to any and
all Proceedings, notwithstanding that Indemnitee has ceased to be a director,
officer, employee, trustee or agent of the Company or a Related Company.

                                                                          Page 4
<PAGE>

2.   Expense Advances

     2.1.  Generally

     The right to indemnification of Damages conferred by Section 1 shall
include the right to have the Company pay Indemnitee's expenses in any
Proceeding as such expenses are incurred and in advance of such Proceeding's
final disposition (such right is referred to hereinafter as an "Expense
Advance").

     2.2.  Conditions to Expense Advance

     The Company's obligation to provide an Expense Advance is subject to the
following conditions:

          2.2.1.  Undertaking

          If the Proceeding arose in connection with Indemnitee's service as a
director or an officer of the Company (and not in any other capacity in which
Indemnitee rendered service, including service to any Related Company), then
Indemnitee or his representative shall have executed and delivered to the
Company an undertaking, which need not be secured and shall be accepted without
reference to Indemnitee's financial ability to make repayment, by or on behalf
of Indemnitee to repay all Expense Advances if and to the extent that it shall
ultimately be determined by a final, unappealable decision rendered by a court
having jurisdiction over the parties and the question that Indemnitee is not
entitled to be indemnified for such Expense Advance under this Agreement or
otherwise.

          2.2.2.  Cooperation

          Indemnitee shall give the Company such information and cooperation as
it may reasonably request and as shall be within Indemnitee's power.

          2.2.3.  Affirmation

          Indemnitee shall furnish, upon request by the Company and if required
under applicable law, a written affirmation of Indemnitee's good faith belief
that any applicable standards of conduct have been met by Indemnitee.

3.   Procedures for Enforcement

     3.1.  Enforcement

     In the event that a claim for indemnity, an Expense Advance or otherwise is
made hereunder and is not paid in full within sixty days (twenty days for an
Expense

                                                                          Page 5
<PAGE>

Advance) after written notice of such claim is delivered to the Company,
Indemnitee may, but need not, at any time thereafter bring suit against the
Company to recover the unpaid amount of the claim (an "Enforcement Action").

     3.2.  Presumptions in Enforcement Action

     In any Enforcement Action the following presumptions (and limitation on
presumptions) shall apply:

     (a) The Company shall conclusively be presumed to have entered into this
Agreement and assumed the obligations imposed on it hereunder in order to induce
Indemnitee to continue as a director and/or officer of the Company;

     (b) Neither (i) the failure of the Company (including the Company's Board
of Directors, independent or special legal counsel or the Company's
shareholders) to have made a determination prior to the commencement of the
Enforcement Action that indemnification of Indemnitee is proper in the
circumstances nor (ii) an actual determination by the Company, its Board of
Directors, independent or special legal counsel or shareholders that Indemnitee
is not entitled to indemnification shall be a defense to the Enforcement Action
or create a presumption that Indemnitee is not entitled to indemnification
hereunder; and

     (c) If Indemnitee is or was serving as a director, officer, employee,
trustee or agent of a corporation of which a majority of the shares entitled to
vote in the election of its directors is held by the Company or in an executive
or management capacity in a partnership, joint venture, trust or other
enterprise of which the Company or a wholly owned subsidiary of the Company is a
general partner or has a majority ownership, then such corporation, partnership,
joint venture, trust or enterprise shall conclusively be deemed a Related
Company and Indemnitee shall conclusively be deemed to be serving such Related
Company at the request of the Company.

     3.3.  Attorneys' Fees and Expenses for Enforcement Action

     In the event Indemnitee is required to bring an Enforcement Action, the
Company shall indemnify and hold harmless Indemnitee against all of Indemnitee's
fees and expenses in bringing and pursuing the Enforcement Action (including
attorneys' fees at any stage, including on appeal); provided, however, that the
Company shall not be required to provide such indemnity for such attorneys' fees
or expenses if a court of competent jurisdiction determines that each of the
material assertions made by Indemnitee in such Enforcement Action was not made
in good faith or was frivolous.

                                                                          Page 6
<PAGE>

4.   Limitations on Indemnity; Mutual Acknowledgment

     4.1.  Limitation on Indemnity

     No indemnity pursuant to this Agreement shall be provided by the Company:

     (a) On account of any suit in which a final, unappealable judgment is
rendered against Indemnitee for an accounting of profits made from the purchase
or sale by Indemnitee of securities of the Company in violation of the
provisions of Section 16(b) of the Securities Exchange Act of 1934 and
amendments thereto; or

     (b) For Damages that have been paid directly to Indemnitee by an insurance
carrier under a policy of officers' and directors' liability insurance
maintained by the Company.

     4.2.  Mutual Acknowledgment

     The Company and Indemnitee acknowledge that, in certain instances, federal
law or public policy may override applicable state law and prohibit the Company
from indemnifying Indemnitee under this Agreement or otherwise.  For example,
the Company and Indemnitee acknowledge that the Securities and Exchange
Commission (the "SEC") has taken the position that indemnification is not
permissible for liabilities arising under certain federal securities laws, and
federal legislation prohibits indemnification for certain ERISA violations.
Furthermore, Indemnitee understands and acknowledges that the Company has
undertaken or may be required in the future to undertake with the SEC to submit
the question of indemnification to a court in certain circumstances for a
determination of the Company's right under public policy to indemnify
Indemnitee.

5.   Notification and Defense of Claim

     5.1.  Notification

     Promptly after receipt by Indemnitee of notice of the commencement of any
Proceeding, Indemnitee will, if a claim in respect thereof is to be made against
the Company under this Agreement, notify the Company of the commencement
thereof; but the omission so to notify the Company will not relieve the Company
from any liability which it may have to Indemnitee under this Agreement unless
and only to the extent that such omission can be shown to have prejudiced the
Company's ability to defend the Proceeding.

                                                                          Page 7
<PAGE>

     5.2.  Defense of Claim

     With respect to any such Proceeding as to which Indemnitee notifies the
Company of the commencement thereof:

     (a) The Company may participate therein at its own expense;

     (b) The Company, jointly with any other indemnifying party similarly
notified, may assume the defense thereof, with counsel satisfactory to
Indemnitee.  After notice from the Company to Indemnitee of its election so to
assume the defense thereof, the Company shall not be liable to Indemnitee under
this Agreement for any legal or other expenses (other than reasonable costs of
investigation) subsequently incurred by Indemnitee in connection with the
defense thereof unless (i) the employment of counsel by Indemnitee has been
authorized by the Company, (ii) Indemnitee shall have reasonably concluded that
there may be a conflict of interest between the Company and Indemnitee in the
conduct of the defense of such action, or (iii) the Company shall not in fact
have employed counsel to assume the defense of such action, in each of which
cases the fees and expenses of counsel shall be at the expense of the Company.
The Company shall not be entitled to assume the defense of any action, suit or
proceeding brought by or on behalf of the Company or as to which Indemnitee
shall have made the conclusion provided for in (ii) above;

     (c) The Company shall not be liable to indemnify Indemnitee under this
Agreement for any amounts paid in settlement of any Proceeding effected without
its written consent;

     (d) The Company shall not settle any action or claim in any manner which
would impose any penalty or limitation on Indemnitee without Indemnitee's
written consent; and

     (e) Neither the Company nor Indemnitee shall unreasonably withhold its, his
or her consent to any proposed settlement.

6.   Severability

     Nothing in this Agreement is intended to require or shall be construed as
requiring the Company to do or fail to do any act in violation of applicable
law.  The Company's inability, pursuant to court order, to perform its
obligations under this Agreement shall not constitute a breach of this
Agreement.  The provisions of this Agreement shall be severable, as provided in
this Section 6.  If this Agreement or any portion hereof shall be invalidated on
any ground by any court of competent jurisdiction, then the Company shall
nevertheless indemnify Indemnitee to the full extent permitted by any applicable
portion of this Agreement that shall not have been

                                                                          Page 8
<PAGE>

invalidated, and the balance of this Agreement not so invalidated shall be
enforceable in accordance with its terms.

7.   Governing Law; Binding Effect; Amendment and Termination

     (a) This Agreement shall be interpreted and enforced in accordance with the
laws of the state of Washington.

     (b) This Agreement shall be binding upon Indemnitee and upon the Company,
its successors and assigns, and shall inure to the benefit of Indemnitee,
Indemnitee's heirs, personal representatives and assigns and to the benefit of
the Company, its successors and assigns.

     (c) No amendment, modification, termination or cancellation of this
Agreement shall be effective unless in writing signed by both parties hereto.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement on and
as of the day and year first above written.

          (2) provided Immunex with a certificate of insurance proving that TGC
or a third party has in force, during the term of this Agreement and reasonable
time thereafter, a policy or policies of insurance including personal and
advertising injury, products and completed operations coverage, which will
indemnify or pay on behalf of Immunex, its directors, officers and employees
against liability claims (including attorneys' fees and legal and other
necessary expenses) for injury or damages arising from the manufacture, use,
sale or distribution of any product or service developed hereunder using the
Information or Biological Materials transferred or licensed to TGC by Immunex
(hereinafter "Claims") and which:

               (i)    is written in an amount not less than ten million dollars
($10,000,000) per occurrence or claim, having a self-insured retention not
greater than one million dollars ($1,000,000), for liability arising out of
bodily injury, personal injury, death or property damage (self-insured
retentions under such policy are the sole responsibility of TGC); and
               (ii)   is endorsed to name Immunex, its directors, officers and
employees as additional insureds under such policy of insurance;
               (iii)  which contains an endorsement that the required coverage
will not be reduced, materially altered, nonrenewed or cancelled without first
giving at least thirty (30) days' prior written notice to Immunex;
               (iv)   which is endorsed to provide coverage that is primary and
noncontributory with any insurance or self-insurance program maintained by
Immunex; and
               (v)    which is of a financial and management quality acceptable
to Immunex. Immunex shall have the right to designate a reasonable period
following termination of this Agreement during which TGC shall maintain
insurance as described above if TGC has engaged in any of the acts defined in
subparagraphs (a), (b) or (c) above prior to termination. Immunex and TGC shall
review the requirements of this Section 11.3 from time to time in view of TGC's
scientific, clinical and financial progress, in order to remove any unreasonable
impediments to TGC's operations while protecting Immunex from liability for
Claims resulting from TGC's operations hereunder.

jurisdiction.

     2.03  Licensed Process(es) means processes which, in the course of being
practiced would, in the absence of this Agreement, infringe one or more claims
of the Licensed Patent Rights that have not been held invalid or unenforceable

may require LICENSEE to submit documentation in confidence showing a reasonable
relationship between the pricing of a Licensed Product, the public investment in
that product and the health and safety needs of the public. This paragraph shall
not restrict the right of LICENSEE to price a Licensed Product or Licensed
Process so as to obtain a reasonable profit for its sale or use. This Paragraph
4.02 does not permit PHS or any other government agency to set or dictate prices
for Licensed Products or Licensed Processes.
<PAGE>

     5.  ROYALTIES AND REIMBURSEMENT
     -------------------------------

     5.01  LICENSEE agrees to pay to PHS a noncreditable, nonrefundable license
issue royalty as set forth in Appendix C within thirty (30) days from the date
that this Agreement becomes effective.

     5.02  LICENSEE agrees to pay to PHS a nonrefundable minimum annual royalty
as set forth in Appendix C. The minimum annual royalty is due and payable on
January 1 of each calendar year, and may be credited against any earned
royalties due for sales made in that year. The minimum annual royalty for the
first calendar year of this Agreement is due and payable within thirty (30) days
from the effective date of this Agreement and may be prorated according to the
fraction of the calendar year remaining between the effective date of this
Agreement and the next subsequent January l.

     5.03  LICENSEE agrees to pay PHS earned royalties as set forth in Appendix
C.

     5.04  A claim of a patent application licensed under this Agreement shall
cease to fall within the Licensed Patent Rights for purposes of computing the
minimum annual royalty and earned royalty payments in any given country on the
earliest of the dates that it: (a)  has been abandoned but not continued, or (b)
has been pending (including the pendency time of any parent cases) but not
allowed for more than six (6) years from its effective filing date; but shall be
reinstated for purposes of computing these royalty payments on the date that a
patent issues thereon. A claim of a patent licensed under this Agreement shall
cease to fall within the Licensed Patent Rights for the purpose of computing the
minimum annual royalty and earned royalty payments in any given country on the
earliest of the dates that: (a) the patent expires, (b) the patent is no longer
maintained by the Government, or (c) all claims of the Licensed Patent Rights
have been held to be invalid or unenforceable by an unappealed or unappealable
decision of a court of competent jurisdiction or administrative agency.

     5.05  No multiple royalties shall be payable because any Licensed products
or Licensed Processes are covered by more than one of the Licensed Patent
Rights.

     5.06  On sales of Licensed products by LICENSEE in other than an arm's
1ength transaction, the Net Sales Price attributed under this Article 5 to such
a transaction shall be that which would have been received in an arm's length
transaction, based on sales of like quantity and quality products on or about
the time of such transaction.

     5.07  LICENSEE agrees to pay PHS, within (60) days of PHS's submission of a
statement and request for payment, a royalty amount
<PAGE>

equivalent to all patent expenses previously incurred by PHS in the preparation,
filing, prosecution and maintenance of Licensed Patent Rights incurred during
the previous calendar year, to be divided equally among all nonexclusive
LICENSEES of record as of the date the statement and request for payment is sent
by PHS to LICENSEE.  [*] of the cumulative amount of such payments may be
credited against royalties due under Paragraph 5.03, however, the net royalty
payment in any calendar year may not be lower than the minimum annual royalty
specified in Appendix C. LICENSEE may elect to surrender its rights in any
country of the Licensed Territory under any Licensed Patent Rights upon sixty
(60) days written notice to PHS and owe no payment obligation under this
Paragraph for subsequent patent-related expenses incurred in that country.

     6. RECORD KEEPING
        --------------

     6.01  LICENSEE agrees to keep, accurate and correct records of Licensed
Products made, used or sold and Licensed Processes practiced under this
Agreement appropriate to determine the amount of royalties due PHS. Such records
shall be retained for at least five (5) years following a given reporting
period. They shall be available during normal business hours for inspection at
the expense of PHS by an accountant or other designated auditor selected by PHS
for the sole purpose of verifying reports and payments hereunder. The accountant
or auditor shall only disclose to PHS information relating to the accuracy of
reports and payments made under this Agreement. If an inspection shows an
underreporting or underpayment in excess of ten percent (10%) for any twelve
(12) month period, then LICENSEE shall reimburse PHS for the cost of the
inspection at the time LICENSEE pays the unreported royalties.

     7. REPORTS ON PROGRESS SALES AND PAYMENTS
        --------------------------------------

     7.01  Prior to signing this Agreement, LICENSEE has provided to PHS a
written commercialization plan ("Commercial Development Plan") under which
LICENSEE intends to bring the subject matter of the Licensed Patent Rights into
commercial use upon execution of this Agreement. The Commercial Development Plan
is hereby incorporated by reference into this Agreement.

     7.02  LICENSEE shall provide written annual reports on its product
development progress or efforts to commercialize under the Commercial
Development Plan for each of the Licensed Fields of Use within sixty (60) days
after December 31 of each calendar year. These progress reports shall include,
but not be limited to: progress on research and development, status of
applications for regulatory approvals, manufacturing, marketing and sales during
the preceding calendar year, as well as plans for the present calendar

_____________________
[ * ] = omitted, confidential material, which material has been separately filed

treatment.
<PAGE>

year. LICENSEE agrees to provide any additional data reasonably required by PHS
to evaluate LICENSEE's performance.

     7.03  LICENSEE shall report to PHS the date of the First Commercial Sale of
Licensed Products or the First Commercial Use of Licensed Processes in each
country in the Licensed Territory within thirty (30) days of such occurrence.

     7.04  LICENSEE shall submit to PHS within sixty (60) days after each
calendar half year ending June 30 and December 31, a royalty report setting
forth for the preceding half year period the amount of the Licensed Products
sold or Licensed Processes practiced by or on behalf of LICENSEE in each country
within the Licensed Territory, the Net Sales, and the amount of royalty
accordingly due. With each such royalty report, LICENSEE shall submit payment of
the earned royalties due. If no earned royalties are due to PHS for any
reporting period, the written report shall so state. The royalty report shall be
certified as correct by an authorized officer of LICENSEE and shall include a
detailed listing of all deductions made under Paragraph 2.05 to determine Net
Sales or made under Article 5 to determine royalties due.

     7.05  Royalties due under Article 5 shall be paid in U. S. dollars. For
conversion of foreign currency to U. S. dollars, the conversion rate shall be
the rate quoted in the Wall Street Journal on the day that the payment is due.
All checks and bank drafts shall be drawn on United States banks and shall be
payable to NIH/Patent Licensing at the address on the Signature Page below.  Any
loss of exchange, value, taxes or other expenses incurred in the transfer or
conversion to U. S. dollars shall be paid entirely by LICENSEE.

     7.06  Late charges will be applied to any overdue payments as required by
the U. S. Department of Treasury in the Treasury Fiscal Requirements Manual,
Section 8020.20. The payment of such late charges shall not prevent PHS from
exercising any other rights it may have as a consequence of the lateness of any
payment.

     7.07  All plans and reports required by this Article 7 and marked
"confidential" by LICENSEE shall be treated by PHS as commercial and financial
information obtained from a person, and as privileged and confidential, and to
the extent permitted by law, shall and not be subject to disclosure under the
Freedom of Information Act, 5 U.S.C. (S)552.


     8.  REASONABLE BEST EFFORTS
         -----------------------

     8.01  LICENSEE shall use its reasonable best efforts to introduce the
Licensed Products into the commercial market or apply the Licensed Processes to
commercial use as soon as practicable,
<PAGE>

consistent with sound and reasonable business practices and judgment.
"Reasonable best efforts" for the purpose of this provision shall include, but
not .be limited to, adherence to the Commercial Development Plan. LICENSEE
agrees to apply at least the same level of effort that it applies to the
commercial development of its own products and processes.

     8.02  Upon the First Commercial Sale of Licensed Products or the First
Commercial Use of Licensed Processes, until the expiration of this Agreement,
LICENSEE shall use its reasonable best efforts to keep Licensed Products and
Licensed Processes available to the public.


     9.  INFRINGEMENT AND PATENT ENFORCEMENT
         -----------------------------------

     9.01  PHS and LICENSEE agree to notify each other promptly of each
infringement or possible infringement, as well as any facts which may affect the
validity, scope or enforceability of the Licensed Patent Rights of which either
Party becomes aware.

     9.02  If PHS has been unable to eliminate a substantial infringement within
one year of written notification to the Office of Technology Transfer from
LICENSEE of the existence of a substantial infringement and has not instituted
infringement litigation, LICENSEE shall be excused from the payment of the
minimum annual royalty and earned royalties in any country in which the
substantial infringement occurred. Thereafter, when the substantial infringement
has ceased or an infringement suit has been initiated, PHS shall so notify the
LICENSEE in writing, at which time LICENSEE's obligation to pay such royalties
shall resume as of the date of such notification.

     9.03  In the event that a declaratory judgment action alleging invalidity
of any of the Licensed Patent Rights shall be brought against PHS, PHS agrees to
notify LICENSEE that an action alleging invalidity has been brought. PHS does
not represent that it will commence legal action to defend against a declaratory
action alleging invalidity. LICENSEE shall take no action to compel the
Government either to initiate or to join in any such declaratory judgment
action. Should the Government be made a party to any such suit by motion or any
other action of LICENSEE, LICENSEE shall reimburse the Government for any costs,
expenses or fees which the Government incurs as a result of its defending
against such motion or other action taken in response to the motion. Upon
LICENSEE's payment of all costs incurred by the Government as a result of
LICENSEE's joinder motion or other action, these actions by LICENSEE will not be
considered a default in the performance of any material obligation under this
Agreement.

students, fellows, agents and consultants harmless from and against all
liability, demands, damages, expenses and losses, including but not limited to

     11. TERMINATION AND MODIFICATION OF RIGHTS
         --------------------------------------

     11.01  In the event that LICENSEE is in default in the performance of any
material obligations under this Agreement, and if the default has not been
remedied within ninety (90) days after the date of notice in writing of such
default, PHS may terminate this Agreement by written notice.

     11.02  At least 30 days prior to filing a petition in bankruptcy LICENSEE
must inform PHS in writing of its intention to file the petition in bankruptcy
or of a third party's intention to file an involuntary petition in bankruptcy.

     11.03  In the event that LICENSEE becomes insolvent, makes an assignment of
Licensed Patent Rights for the benefit of creditors, files a petition in
bankruptcy, has such a petition filed against it, determine to file the petition
in bankruptcy, or receives notice of a third party's intention to file an
involuntary petition
<PAGE>

in bankruptcy, LICENSEE shall immediately notify PHS in writing. Furthermore,
PHS shall have the right to terminate this Agreement by giving LICENSEE written
notice. Termination of this Agreement is effective upon LICENSEE'S receipt of
the written notice.

     11.04  LICENSEE shall have a unilateral right to terminate this Agreement
and/or any licenses in any country by giving PHS sixty (60) days written notice
to that effect.

     11.05  PHS shall specifically have the right to terminate this Agreement,
if PHS determines that the LICENSEE: (1) is not executing the Conmmercial
Development Plan submitted with its request for a license and the LICENSEE
cannot otherwise demonstrate to PHS's satisfaction that the LICENSEE has taken,
or can be expected to take within a reasonable time, effective steps to achieve
practical application of the Licensed Products or Licensed Processes; (2) has
willfully made a false statement of, or willfully omitted, a material fact in
the license application or in any report required by the licensed agreement; (3)
has committed a substantial breach of a covenant or agreement contained in the
license; (4) is not keeping Licensed Products or Licensed Processes reasonably
available to the public after commercial use commences; (5) cannot reasonably
satisfy unmet health and safety needs; or (6) cannot reasonably justify a
failure to comply with the domestic production requirement of Paragraph 4.02
unless waived. In making this determination, PHS will take into account the
normal course of such commercial development programs conducted with sound and
reasonable business practices and judgment and the annual reports submitted by
LICENSEE under Paragraph 7.02. Prior to invoking this right, PHS shall give
written notice to LICENSEE providing LICENSEE specific notice of and a ninety
(90) day opportunity to satisfy PHS's concerns as to the previous items (1) to
(6). If LICENSEE fails to satisfy or reasonably begin to rectify such concerns
within the ninety (90) day period, PHS may terminate this Agreement.

     11.06  PHS reserves the right according to 35 U.S.C. (S)209(f) (4) to
terminate this Agreement if it is determined that such action is necessary to
meet requirements for public use specified by Federal regulations issued after
the date of the license and such requirements are not reasonably satisfied by
LICENSEE.

     11.07  Within thirty (30) days of receipt of written notice of PHS's
unilateral decision to terminate this Agreement, LICENSEE may, consistent with
the provisions of 37 C.F.R. (S)404.11, appeal the decision by written submission
to the Assistant Secretary for Health or designee. The Assistant Secretary for
Health or designee's decision shall be the final agency decision. LICENSEE may
thereafter exercise any and all administrative or judicial remedies that may be
available.
<PAGE>

     11.08  Within ninety (90) days of termination of this Agreement under this
Article 11 or expiration under Paragraph 3.03, a final report shall be submitted
by LICENSEE. Any royalty payments and unreimbursed patent expenses due to PHS
become immediately due and payable upon termination.

survive termination of this Agreement.


     12. GENERAL PROVISIONS
         ------------------

     12.01  Neither Party may waive or release any of its rights or interests in
this Agreement except in writing. The failure of the Government to assert a
right hereunder or to insist upon compliance with any term or condition of this
Agreement shall not constitute a waiver of that right by the Government or
excuse a similar subsequent failure to perform any such term or condition by
LICENSEE.

     12.02  This Agreement constitutes the entire agreement between the Parties
relating to the subject matter of the Licensed Patent Rights, and all prior
negotiations, representations, agreements and understandings are merged into,
extinguished by and completely expressed by this Agreement.

     12.03  The provisions of this Agreement are severable, and in the event
that any provision of this Agreement shall be determined to be invalid or
unenforceable under any controlling body of law, such determination shall not in
any way affect the validity or enforceability of the remaining provisions of
this Agreement.

     12.04  If either Party desires a modification to this Agreement, the
Parties shall, upon reasonable notice of the proposed modification by the Party
desiring the change, confer in good faith to determine the desirability of such
modification. No modification will be effective until a written amendment is
signed by the signatories to this Agreement or their designees.

     12.05  The construction, validity, performance and effect of this Agreement
shall be governed by Federal law as applied by the Federal Courts in the
District of Columbia.

     12.06  All notices required or permitted by this Agreement shall be given
by prepaid registered or certified mail properly addressed to the other Party at
the address designated on the following signature page, or to such other address
as may be designated in writing by such other Party, and shall be effective as
of the date of the postmark of such notice.
<PAGE>

     12.07  This Agreement shall not be assigned by LICENSEE except (a) with the
prior written consent of PHS, such consent to be reasonably given; or (b) as
part of a sale or transfer of substantially the entire business of LICENSEE
relating to operations which concern this Agreement.

     12.08  LICENSEE agrees in its practice of the Licensed Patent Rights to
comply with all applicable Government regulations and guidelines including, for

the United States laws and regulations (including the Export Administration Act
of 1979 and Arms Export Control Act) controlling the export of technical data,
computer software, laboratory prototypes, biological material and other
commodities. The transfer of such items may require a license from the cognizant
agency of the U. S. Government or written assurances by LICENSEE that it shall
not export such items to certain foreign countries without prior approval of
such agency. PHS neither represents that a license is or is not required or
that, if required, it shall be issued.

     12.10  LICENSEE agrees to mark the Licensed Products or their packaging
sold in the United States with all applicable U. S. patent numbers and similarly
to indicate "Patent Pending" status. All Licensed Products manufactured in,
shipped to or sold in other countries shall be marked in such a manner as to
preserve PHS patent right in such countries.

     12.11  By entering into this Agreement, PHS does not directly or indirectly
endorse any product or service provided, or to be provided, by LICENSEE whether
directly or indirectly related to this Agreement. LICENSEE shall not state or
imply that this Agreement is an endorsement by the Government, PHS, any other
Government organizational unit, or any Government employee. Additionally,
LICENSEE shall not use the names of PHS, NIH, CDC or ADAMHA or their employees
in any advertising, promotional or sales literature without the prior written
consent of PHS.

     12.12  The Parties agree to attempt to settle amicably any controversy or
claim arising under this Agreement or a breach of the Agreement, except for
appeals of modification or termination decisions provided for in Article 11.
LICENSEE agrees first to appeal any such unsettled claims or controversies to
the Director of NIH, whose decision shall be considered the final agency
decision. Thereafter, LICENSEE may exercise any administrative or judicial
remedies that may be available.

     12.13  Nothing relating to the grant of a license, nor the grant itself,
shall be construed to confer upon any person any
<PAGE>

immunity from or defenses under the antitrust laws or from a charge of patent
misuse and the acquisition and use of rights pursuant to this part shall not be
immunized from the operation of state or Federal law by reason of the source of
the grant.

material obligation under this Agreement.

essentially similar to the terms of this Agreement. PHS will advise LICENSEE as
to those terms in other agreements under Licensed Patent Rights in the Licensed
Fields of Use in the Licensed Territory signed after the effective date of this
Agreement that are different from this Agreement as to Minimum Annual Royalty,
Benchmark Royalty or Earned Royalty or the basis on
<PAGE>

which these royalties are computed. LICENSEE may determine whether such package
of royalty terms are more favorable than those granted under this Agreement, and
shall be entitled upon written notice to PHS, within sixty (60) days after
receipt from PHS of the different terms, to have this Agreement amended to
substitute this package of terms as of the date upon which more favorable
license terms become effective.

  13.02  PHS may have entered into prior license agreement for Licensed Patent
Rights.  The Article 13 does not apply to the royalty terms for past sales or
any settle agreements of infringement suits.

           failure to perform any such term or condition by the other party.

     15.6  If UFRFI grants a license under the Patent Rights to any third party
           that requires a royalty rate lower than that required of LICENSEE
           under this Agreement, then UFRFI shall offer those terms to LICENSEE,
           to be effective as of the effective date of the license to such third
           party.

2.   Disclosure and Evaluation

     (a) University shall provide Company with a copy of each U.S. and/or
     foreign Patent Application filed on the Invention during or before the
     Option Exercise Period.  Company shall, based upon such disclosure and/or
     any disclosure made in accordance with the Confidentiality Agreement,
     evaluate the technical, economic and commercial advantages of the
     Invention.

     (b) University shall also furnish to Company reasonable opportunity to
     confer with the Inventor(s) of the Invention.

     (c) The right to evaluate the Patent Rights and granted herein shall not
     include the right to sell or otherwise furnish to any third party the
     Invention, or any product made thereby, nor shall it include the right to
     disclose any product made thereby to any third party.

3.   Consideration

     Company hereby agrees to pay to University all costs, including attorney's
     fees, associated with the preparation, filing, prosecution, issuance and

     make its own filings.

     (d) As further consideration for the granting of the Option, Company agrees
     to pay to the University, within 30 days of the Effective Date, the amount
     of [ * ] U.S. dollars.

     Option may be exercised by Company at any time during the Option Exercise
     Period upon written notice to University. In the event that Company
     exercises the Option, the parties shall commence good faith negotiations
     forthwith regarding the terms of the license.

     (b) The Option Exercise Period may be extended if Company continues to
     sponsor research directly relating to the Invention for a time period and
     at an amount not less than the budget of the existing Sponsored Research
     Agreement between Company and University. Such option shall extend for an
     additional [ * ] months beyond the expiration of any subsequent Sponsored
     Research Agreements, however, in no event shall the Option Exercise period
     be greater than [ * ] years from the Effective Date of this Agreement ([ *
     ]).

     (c) If Company wishes to extend the Option Exercise Period without
     sponsoring additional research at the University in the Inventor's
     laboratory, it may do so at a cost of $[ * ] for each additional year,
     however, in no event shall the Option Exercise period be greater than [ * ]
     years from the Effective Date of this Agreement ([ * ]).

     (d) Any amounts paid under this Article 4 shall not be refundable under any
     circumstances, nor shall such amounts be a credit against future royalties
     or other income related to the Invention.

5.   Termination

     (a) If the Option granted by University pursuant to Article 4 hereof is not
     exercised by Company within the Option Exercise Period this Option
     Agreement shall terminate on [ * ] (or such other date as is consistent
     with any extension of the Option Exercise Period pursuant to Article 4 (b)
     hereof). If the Option granted by University pursuant to Article 4 hereof
     is exercised by Company within the Option Exercise Period and if University
     and Company have not negotiated and executed a license agreement within [ *
     ] days of the date Company notifies University that it intends to exercise
     this Option this Option Agreement shall terminate on the expiration of such
     [ * ]-day period, provided that such date may be extended by mutual consent
     of the parties in writing, such consent not to be unreasonably withheld by
     either party.

     (b) Company may terminate the Option Exercise Period at any time by
     notifying University in writing of its decision not to exercise said
     option. In such event, Company's obligations for reimbursement of patent
     expenses under Article 3 hereof shall terminate on the date University
     receives written notice of termination; however, Company shall be obligated
     to reimburse University for all patent application expenses incurred
     through the date of University's receipt of notice of termination, whether
     or not Company or University have been billed for such expenses as of said
     date.

     promptly return to University any and all patent applications filed or
     drafted pursuant to this Option Agreement, including any complete or
     partial copies thereof made by or on behalf of Company.

6.   Default

     herein provided, any obligation or condition required to be performed or
     fulfilled by Company hereunder, and if Company shall fail to remedy such
     default within sixty (60) days after written notice thereof from
     University, University shall have the right to terminate this Option
     Agreement by written notice of termination to Company. Any termination of
     this Agreement pursuant to this Article 7 shall be in addition to, and
     shall not be exclusive of or prejudicial to, any other rights or remedies
     at law or in equity that University may have on account of the default of
     Company.

          excess of any work or service Landlord is obligated to furnish to
          Tenant at Landlord's expense;
<PAGE>

     (j)  principal and interest payments on loans secured by mortgages or deeds
          of trust on, or assignments of rent from, all or any portion of the
          Premises;

     (k)  depreciation;

     (1)  penalties due to any violation of law by Landlord or other tenants;

     (m)  costs of preparing tenant space for tenant occupancy;

     (n)  costs of any utilities, services or capital improvements relating to
          all or any portion of the Premises that were paid directly by Tenant
          or any other tenant;

     (o)  costs allocable to properties other than the Building in which the
          Premises are located in which Landlord has an interest;

     (p)  structural repairs or replacements; and

     (q)  rent payable in connection with any ground or underlying lease.

It is agreed by Tenant that in addition to Tenant's Proportionate Share of
Operating Expenses, Tenant shall be solely responsible for providing and paying
for janitorial services for the Premises; water and sewer services; electrical
services; air conditioning and heating services (including electricity
therefor); and plumbing services; as those items relate to the Premises.
Landlord will establish at its sole cost and expense separate meters for, or if
meters cannot be installed, will separately and equitably calculate the charges
for, the utilities supplied to the Premises.

     8.02  Tenant's Proportionate Share. Commencing with respect to the 1994
Comparison Year (as defined below), in addition to the Base Rent payable
pursuant to Article 6, Tenant shall pay, as additional rent, Tenant's
Proportionate Share of the increase in total Operating Expenses in each
Comparison Year over the total Operating Expenses incurred by Landlord during
the Base Year. For purposes of this Lease (including any extensions), the Base
Year shall be calendar year 1993. Each succeeding year shall be a Comparison
Year.

Tenant's Proportionate Share will be determined in accordance with paragraph 2
above.

Landlord shall give to Tenant on or before the first day of June, 1994 and on or
before the first day of June of each year thereafter during the term of this
Lease, an itemized statement of the increase in rent payable by Tenant hereunder
for the preceding Comparison Year, but failure by Landlord to give such
statement by said date shall not constitute a waiver by Landlord of its right to
require an increase in rent.

For calendar year 1994, Landlord shall deliver to Tenant, no later than June 1,
1994, an estimate of the Operating Expense increase over the Base Year which
will be due for 1994. Said estimated increased amount shall be divided into
equal installments to be paid each month remaining in the calendar year
<PAGE>

1994, commencing with the month following Tenant's receipt of Landlord's
estimate, provided that payments for 1994 shall not be due for any month prior
to the month following the date which is twelve (12) months from the
Commencement Date. For example, if Landlord's estimate is delivered in February,
1994, and the Commencement Date is April 1, 1993, the estimated annual increase
shall be divided into eight equal installments and paid each month, May through
December, 1994.

For years after 1994, upon receipt of the statement for the preceding Comparison
Year, Tenant shall pay a lump sum equal to the total amount of increase in
Operating Expenses over the Base Year, less amounts previously paid on account
thereof as estimated increases. In addition, the amount of any such increase
shall be used as the basis for an estimate of the increase due for the current
year, and that amount shall be divided into equal installments to be paid each
month remaining in the calendar year, commencing with the month following
Tenant's receipt of Landlord's estimate. For example, if Landlord's estimate is
delivered in February, the estimated annual increase shall be divided into ten
equal installments and paid each month, March through December.

If in any Comparison Year the Tenant's share of Operating Expenses are less than
the preceding year, then upon receipt of Landlord's statement, any overpayment
made by Tenant on the monthly installment basis provided above shall be credited
towards the next monthly rent falling due and the estimated monthly installments
of Operating Expenses to be paid shall be adjusted to reflect such lower
Operating Expenses for the most recent Comparison Year.

Tenant, at reasonable times and upon reasonable notice, shall have the right to
inspect Landlord's books and records pertaining to the Building and the
determination of Operating Expenses.

Even though the term has expired and Tenant has vacated the Premises, when the
final determination is made of Tenant's share of Operating Expenses for the year
in which this Lease terminates, Tenant shall immediately pay any increase due
over the estimated expenses paid and conversely any overpayment made in the
event said expenses decrease shall be immediately rebated by Landlord to Tenant.

The statements furnished to Tenant by Landlord, which shall contain such
supporting documentation as Tenant may reasonably request, shall constitute a
final determination as between Landlord and Tenant of Operating Expenses for the
periods represented thereby, unless Tenant, within 60 days after they are
furnished, shall give a notice to Landlord that it disputes their accuracy or
their appropriateness, which notice shall specify the particular respects in
which the statement is inaccurate or inappropriate. Any such dispute shall be
resolved (a) by arbitration in the Seattle, Washington area by 3 arbitrators,
each of whom shall have at least 10 years' experience in the supervision of the
operation and management of projects in Seattle, Washington, like the project in
which the Premises are located and (b) in accordance with the Commercial
Arbitration Rules of the American Arbitration Association, and judgment upon the
award rendered by the arbitrators may be entered in any court having
jurisdiction thereof. Pending the
<PAGE>

resolution of such dispute, Tenant shall continue to pay additional rent to
Landlord in the same amounts as before Tenant received the statement that is the
subject of such dispute. Within 30 days after the resolution of such dispute,
Tenant shall pay to Landlord any deficiency in additional rent found by the
arbitrators to be owing to Landlord by Tenant.

The Base Rent payable by Tenant shall in no event be less than the Base Rent
specified in Article 6 even if Operating Expenses incurred by Landlord in any
Comparison Year are less than those incurred in the Base Year.

costs of installation, operating and maintenance of those units shall be paid by
Tenant to Landlord upon demand.

pursuant to the Tenant's Final Plans shall be paid for by Tenant promptly upon

Notice for a period of five (5) days following receipt of Landlord's notice of
termination; or

square feet of the Tenant's premises and Landlord shall not have the right to
terminate pursuant to Paragraph 14.0l(a)(i) as to any of said 10,000 square

with respect to such space shall not affect the force or validity of the Lease
with respect to the remainder of the Premises, provided that the Rent payable
hereunder shall be adjusted on a pro rata basis in accordance with the reduction
in the rentable area of the Premises. If Landlord shall fail to notify Tenant in
writing of its election under subparagraph (a) within the fifteen business (15)
day period, Landlord shall be deemed to have waived the option described in

transferee within fifteen business (15) days of receipt of complete financial
statements and business history information including the name and legal

in excess of the Base Rent and Tenant's Share of Operating Costs payable under

Landlord.
<PAGE>

     (d) The consent of Landlord to any Transfer shall not release Tenant from
any of Tenant's obligations hereunder or discharge any liability of Tenant under
this Lease, nor shall said consent be deemed to be a consent to any subsequent
similar or dissimilar Transfer. Any such Transfer, without such consent shall be
void and shall constitute, at the option of Landlord, a material default
hereunder. The acceptance of rent by Landlord from any other person or entity
shall not be deemed to be a waiver by Landlord of any provision of this Lease or
to be a consent to any Transfer thereof.

     (e) For purposes of this Article 14, sales, transfers or assignments, in
any single transaction, of a controlling interest in the stock of Tenant shall
constitute a Transfer hereunder.

assigned to Landlord in which event the tenants under such subleases shall
become tenants of Landlord.

connection with its review and consideration of any proposed Transfer, including

corporation is at least equal to the greater of (a) the net worth of Tenant on
the date hereof or (b) the net worth of Tenant immediately prior to such merger
or consolidation; provided, further, any such assignment of lease shall contain
an assumption of all of the terms, covenants and conditions of this Lease to be
performed, and any subtenant shall agree to perform all applicable provisions of
this Lease to be performed by Tenant. Tenant agrees that no such assignment or
subletting shall be effective unless and until Tenant gives Landlord written
notice thereof, together with a true copy of the assignment or of the sublease.

     14.02  Assignment by Landlord. Landlord may assign, encumber or dispose of
all or any part of its interest in the Building, Premises or this Lease without
affecting this Lease or Tenant's obligations. Tenant agrees to accept and

damage. Tenant may, within ten (10) days after receipt of Landlord's notice,
give written notice to Landlord of Tenant's intention to repair the damage at
Tenant's expense, without reimbursement from Landlord. This Lease will then
continue in full force and Tenant shall make repairs as soon as reasonably
possible. If Tenant does not give its notice after Landlord elects termination,
this Lease shall be canceled and terminated as of the date of the occurrence of
damage.

     17.03  Damage Near End of Term. If the Premises are partially destroyed or
damaged during the last six months of the term of this Lease, Landlord or Tenant
may at its option cancel and terminate this Lease as of the date of occurrence
of damage by giving written notice to the other of that election within thirty
(30) days after the date of occurrence of damage.

     17.04  Total  Destruction. If the Premises are totally destroyed from any
cause whether or not covered by insurance (including any total destruction
required' by any authorized public authority), this Lease shall automatically
terminate as of the date of total destruction.

     17.05 Abatement of Rent: Tenant's Remedies. The Base Rent payable under
Articles 6 and 8 for the period from the date of the casualty until repairs are
completed shall be abated in proportion to the degree of impairment of Tenant's
use of the Premises. Except for abatement of rent, Tenant shall have no claim
against Landlord for any damage suffered for any partial damage, destruction, or
repair of the Premises unless caused by the negligence or willful misconduct of
Landlord or Landlord's agents, employees or contractors. If Landlord does not
commence repairs within forty--five (45) days after its obligation to repair
accrues under this Article, Tenant may at its option cancel this Lease by giving
Landlord written notice at any time prior to the commencement of repairs. This
Lease will terminate as of the date of that notice.

18.  CONDEMNATION

If the Premises or any portion thereof are taken under the power of eminent
domain, or sold under the threat of its exercise (a "condemnation"), this Lease
shall terminate as to the part taken as of the date the condemning authority
takes title or possession, whichever is earlier. If more than ten percent (10%)
of the floor area of the Premises, or more than twenty-
<PAGE>

five percent (25%) of the land area of the property which is not occupied by any
improvements, is taken by condemnation, or if by condemnation a material change
in the character of the Premises prevents their continued use in substantially
the same manner as before the condemnation, Tenant may, at its option, terminate
this Lease as of the date the condemning authority takes possession. Tenant must
exercise its option in writing within ten (10) days after the condemning
authority takes possession. If Tenant does not terminate this Lease, it shall
remain in full force as to the remaining Premises, except that the Base Rent,
and Tenant's Proportionate Share, shall be reduced in the proportion that the
floor area taken bears to the total original floor area of the Premises. Any
award for taking all or any part of the Premises by condemnation, or any payment
made under threat of condemnation, is the property of Landlord, whether the
award is made as compensation for diminution in value of the leasehold, for the
taking of the fee, or as severance damages. Tenant is entitled to any award for
loss of or damage to its trade fixtures, removable personal property, and for
the cost of the unamortized portion of Tenant's improvements. If this Lease is
not terminated after condemnation, Landlord shall, to the extent of severance
damages received by it, repair any damage to the Premises caused by the
condemnation, except to the extent that Tenant was reimbursed therefor by the
condemning authority. Nothing in this Lease shall prevent Tenant from pursuing
its own damage claim against the condemning authority.

19.  DEFAULTS: REMEDIES

     19.01  Defaults. Each of the following is a material default and breach of
this Lease by Tenant:

     (a)  Vacating or abandoning the Premises for more than thirty (30)
          consecutive days;

     (b)  Failure to make any required rent or other payment as and when due if
          such failure continues for a period of five (5) business days after
          written notice thereof from Landlord;

     (c)  Failure to comply with any of the covenants or provisions of this
          Lease, other than those described in subparagraph (b), if the failure
          continues for a period of thirty (30) days after written notice from
          the Landlord. If the nature of Tenant's default reasonably requires
          more than thirty (30) days for its cure, Tenant will not be in default
          if it commences to cure with the thirty (30) day period and thereafter
          diligently pursues its completion.

     (d)  Tenant's making any general assignment or arrangement for the benefit
          of creditors; the filing by or against Tenant of a petition to have it
          adjudged a bankrupt or a petition for reorganization or arrangement
          under any bankruptcy law (unless, any petition filed against Tenant is
          dismissed within sixty (60) days); the appointment of a trustee or
          receiver to take possession of substantially all of Tenant's assets at
          the Premises or its interest in this Lease, if possession is not
          restored to Tenant within sixty
<PAGE>

          (60) days; or the attachment, execution or other judicial seizure of
          substantially all of Tenant's assets at the Premises or its interest
          in this Lease, if that seizure is not discharged within sixty (60)
          days.

     (e)  Discovery by Landlord that any financial statement given to Landlord
          by Tenant, or by any assignee, subtenant, successor in interest of
          Tenant, or any guarantor of its obligations was materially false at
          the time given.

    19.02  Remedies. If any material default or breach by Tenant occurs,
    Landlord may at any time thereafter without notice or demand do any or all
    of the following:

     (a)  Terminate Tenant's right to possession of the Premises by any lawful
          means, and this Lease shall terminate; Landlord may reenter and take
          possession of and remove all persons or property, and Tenant shall
          immediately surrender possession of the Premises to Landlord. Landlord
          may recover from Tenant all damages incurred by Landlord for Tenant's
          default including, but not limited to, the cost of recovering
          possession of the Premises; expenses of reletting, including necessary
          and reasonable renovation and alteration of the Premises.

          Landlord may also recover reasonable attorney's fees and any real
          estate commissions actually paid in connection with any reletting of
          the Premises; the worth at the time of award by a court of competent
          jurisdiction of the amount by' which the unpaid rent for the balance
          of the term after the time of the award exceeds the amount of rent
          loss for the same period that Tenant proves could be reasonably
          avoided; and any leasing commission applicable to the unexpired term
          of this Lease (calculated by amortizing the commission over the
          initial term of this Lease).

     (b)  Maintain Tenant's right to possession, and this Lease shall continue
          in force whether or not Tenant has abandoned the Premises. Landlord
          shall be entitled to enforce all of its rights and remedies under this
          Lease, including the right to recover rent as it becomes due.

     (c)  Pursue any other remedy available to Landlord under the law.

These remedies are not exclusive.

     19.03  Default by Landlord. Landlord is not in default unless it fails to
perform obligations required of it within a reasonable time, and not later than
thirty (30) days after delivery of written notice by Tenant to Landlord and to
the holder of any first mortgage or deed of trust covering the Premises whose
name and address has been furnished to Tenant in writing, specifying Landlord's
failure to perform its obligations. If Landlord's obligation reasonably requires
more than
<PAGE>

thirty (30) days for performance or cure, Landlord is not in default if it
commences performance or cure within the thirty (30) day period and thereafter
diligently pursues its completion.

     19.04  Late Charges. Late payment by Tenant of rent and other sums due will
cause Landlord to incur costs not contemplated by this Lease, the exact amount
of which will be extremely difficult to ascertain. The costs include, but are
not limited to, processing and accounting charges, and late charges which may be
imposed on Landlord by the terms of any mortgage or trust deed covering the
Premises. Accordingly, if any installment of rent or any other sums due from
Tenant are not received by Landlord or its designee within ten (10) working days
after the amount is due, Tenant shall pay to Landlord a late charge equal to
five percent (5%) of the overdue amount. The parties agree that this late charge
represents a fair and reasonable estimate of the costs Landlord will incur by
reason of late payment by Tenant. Acceptance of a late charge by Landlord is not
a waiver of Tenant's default, nor a waiver of greater charges which may be
incurred by Landlord.

20.  ESTOPPEL CERTIFICATES

Tenant shall at any time upon ten (10) days' prior written notice from Landlord
execute, acknowledge and deliver to Landlord a statement in writing (i) stating
the Commencement Date and certifying that this Lease is unmodified and in full
force (or, stating the nature of any modification and certifying that this
Lease, as modified is in full force) and stating the date to which the rent and
other charges are paid in advance, if any, and (ii) acknowledging that there are
not, to Tenant's knowledge, any uncured defaults on the part of Landlord (or
specifying any defaults claimed). This statement may be conclusively relied upon
by any prospective purchaser or encumbrancer of the Premises.

Tenant's failure to deliver this statement within ten (10) days shall be
conclusive upon Tenant (i) that this Lease is in full force as represented by
Landlord, (ii) that there are no uncured defaults in Landlord's performance, and
(iii) that not more than one month's rent has been paid in advance. Any such
failure may also be considered by Landlord as a material default by Tenant under
this Lease.

If Landlord desires to finance or refinance the Building or part of it, Tenant
agrees to provide reasonable financial information to any lender in order to
facilitate financing or refinancing. These financial statements shall be
remitted directly to the lender and shall be kept confidential by the lender.

21.  BROKER

Landlord and Tenant each warrant to the other that it has had no dealings with
any real estate broker or agent in connection with the negotiation of this
Lease, except CB Commercial Real Estate, Inc., which represented Landlord, and
Teutsch Partners, which represented Tenant, and that it knows of no other real
estate broker or agent who is or might be entitled to a commission in connection
with this Lease. If Landlord or Tenant has
<PAGE>

dealt with any other person or real estate agent with respect to leasing or
renting space in the Building, such party shall be solely responsible for the
payment of any fee due said person or firm, and Landlord and Tenant shall each
indemnify and hold the other harmless from and against any liability in respect
thereof. Landlord acknowledges that it shall pay to CB Commercial Real Estate
Inc., as listing broker, a total of six and one--half percent (6.5%) of the
gross lease consideration (base rent only) for years one through five and three
and one--quarter percent (3.25%) of the gross lease consideration (base rent
only) for year 6, and CB Commercial Real Estate, Inc. shall be solely
responsible for and liable to compensate Teutsch Partners (as co--broker) a
total of four percent (4%) of the gross lease consideration (base rent only) for
years one through five and two percent (2%) of the gross lease consideration
(base rent only) for year six. Such payment shall be made one-half on the date
the Lease is fully executed by both Landlord and Tenant and the Master Use
Permit permitting Tenant's use of the Premises has been issued, and one--half on
the date Tenant has occupied the Premises for its business use and has commenced
paying rent.

22.  SUBORDINATION

This Lease, at Landlord's option, shall be subordinate to any ground lease,
mortgage, deed of trust, any other hypothecation for security or encumbrance
upon the real property of which the Premises are a part and to any and all
advances made on that security and to all renewals, modifications,
consolidations, replacements and extensions thereof. Despite any subordination,
Tenant's right to quiet possession of the Premises shall not be disturbed and
none of Tenant's other rights under this Lease shall be diminished if Tenant is
not in default under this Lease. If any mortgagee, trustee, or ground lessor
prefers to have this Lease prior to the lien of its mortgage, deed or trust or
ground lease, and gives written notice to Tenant, this Lease shall be prior to
that mortgage, deed of trust, or ground lease, whether this Lease is dated prior
to or subsequent to the date of the mortgage, deed of trust or ground lease or
its recording date.

Tenant will execute any documents required to effectuate subordination or make
this Lease prior to any mortgage, deed of trust or ground lease within ten (10)
days after written request. Notwithstanding the foregoing, Tenant shall not be
required to subordinate this Lease to any mortgage or deed of trust unless the
mortgagee or beneficiary agrees with Tenant, pursuant to a nondisturbance
agreement, that upon a foreclosure (or deed in lieu thereof), and as long as
Tenant is not in default hereunder, such mortgagee or beneficiary will recognize
this Lease and all of Tenant's rights hereunder and will not disturb or
interfere with Tenant's occupancy. Landlord represents that, as of the date of
execution of this Lease, there is no mortgage or deed of trust encumbering the
Building or the Premises.

23.  GENERAL PROVISIONS

     23.01  Severability. The invalidity of any provision of this Lease as
determined by a court of competent jurisdiction will not affect the validity of
any other provision.
<PAGE>

     23.02 Time of Essence.  Time is of the essence of this Lease.

     23.03  Incorporation of Prior Agreements; Amendments. This Lease contains
all agreements of the parties with respect to all matters mentioned in it. No
prior agreement or understanding concerning those matters is effective. This
Lease may be modified only in writing, signed by the parties in interest at the
time of the modification.

     23.04  Notices. Any notice given under this Lease shall be in writing and
may be given by personal delivery, facsimile transmission, or by certified mail,
postage prepaid, addressed to Tenant or to Landlord at their addresses in
Article 1. Either party may by notice under this Article change its address for
notice purposes. Notices personally delivered or transmitted by facsimile are
considered received upon delivery. Mailed notices are considered received five
(5) days after deposit in the mail. A copy of all notices given to Landlord
shall be concurrently transmitted to Landlord's lender designated in writing by
Landlord.

     23.05  Waiver. Waiver by Landlord of the breach of any provision of this
Lease is not a waiver of any subsequent breach by Tenant of the same or any
other provision. Landlord's consent to or approval of any act does not make the
Landlord's consent to or approval of any subsequent act unnecessary. Acceptance
of rent by Landlord is not a waiver of any preceding breach of any provision of
this Lease, other than Tenant's failure to pay the rent so accepted.

     23.06  Recording. Tenant shall not record this Lease without Landlord's
prior written consent, and unauthorized recordation, at the option of Landlord,
constitutes a noncurable default by Tenant. Landlord and Tenant shall, upon
request of the other party, execute, acknowledge and deliver to Landlord a
"short form" memorandum of this Lease suitable for recording.

     23.07  Holding Over. Any holding over after the expiration or other
termination of the term of this Lease with the written consent of Landlord
delivered to Tenant shall be construed to be a tenancy from month to month on
all the terms, covenants and conditions herein specified so far as applicable,
except that the Base Rent shall be an amount equal to one hundred twenty-five
percent (125%) of the Base Rent otherwise payable by Tenant immediately prior to
such holding over; provided, however, if such holding over is without the
written consent of Landlord, the Base Rent shall be an amount equal to Two
Hundred percent (200%) of the Base Rent otherwise payable by Tenant immediately
prior to such holding over. Acceptance by Landlord of Rent after the expiration
or termination of this Lease shall not constitute a consent by Landlord to any
such tenancy from month to month or result in any other tenancy or any renewal
of the term hereof. The provisions of this paragraph are in addition to, and do
not affect, Landlord's right to re--entry or other rights provided by this Lease
or by law.

     23.08  Covenants and Conditions. Each provision of this Lease performable
by Tenant is both a covenant and a condition.
<PAGE>

     23.09  Binding Effect. Subject to the provisions restricting assignment or
subletting, this Lease binds and benefits the parties, their personal
representatives, successors and assigns.

     23.10  Common Areas/Access/Parking. All elevators, stairways, halls, public
toilet facilities and other areas for the common use of all tenants of the
building shall be open for reasonable use by Tenant and its employees. Tenant
and its employees shall have twenty-four hour access to the Premises. Tenant
shall have the right to lease up to forty--two (42) non-reserved parking spaces
in the Building parking garage. During the initial term of this Lease (years one
through six) such parking spaces shall be provided at Eighty-Five Dollars
($85.00) per month. Thirty (30) days prior to the Commencement Date, Tenant
shall notify Landlord of the initial number of parking spaces Tenant desires to
lease pursuant to this paragraph. After the Commencement Date, additional
parking spaces up to the allotment of 42 will be made available to Tenant (at
the $85.00 per space rate during the initial term) upon thirty (30) days written
request from Tenant. Tenant may reduce the number of spaces it leases upon
thirty (30) days prior written notice to Landlord. Spaces leased by Tenant but
subsequently given up by Tenant may be used by the Landlord and Tenant's right
to lease those spaces in the future is subject to availability and market rates.
For example, if Tenant initially leased 42 spaces and one year later reduces its
spaces rented to 20 spaces, Tenant would only be able to rent additional spaces
beyond 20 if they were not leased to others, and Tenant would have to pay market
rate for those spaces above 20.

If Tenant leases space in the Building in addition to the initial Premises,
Tenant shall be entitled to lease additional parking spaces at the ratio of one
space for each additional Five Hundred Forty-Six (546) rentable square feet
leased. The parking spaces shall be provided at Eighty-Five Dollars ($85.00) per
month per space during the initial term of this Lease. During any extended term
of this Lease the parking spaces shall be leased to Tenant at market value. All
parking rights and uses are subject to this Lease and any reasonable rules and
regulations of Landlord for such parking facilities which may be established or
altered by Landlord at any time or from time to time during the term thereof.

     23.11  Corporate Authority.   If Tenant is a corporation, each individual
executing this Lease on behalf of that corporation represents and warrants that
he is duly authorized to execute and deliver this Lease on behalf of the
corporation, in accordance with the duly adopted resolution of its Board of
Directors or in accordance with its Bylaws, and that this Lease is binding upon
that corporation in accordance with its terms.

     23.12  Sale of Building. If Landlord's rights in the Building are sold,
Landlord will be relieved of all liability under the covenants and conditions in
this Lease arising out of any act, occurrence or omission after consummation of
the sale upon written assumption of the Lease by the purchaser. The purchaser
shall be deemed, without any further agreement by parties or their successors in
interest, to have assumed and agreed to carry out all of the covenants and
obligations of Landlord under this Lease.
<PAGE>

     23.13  Attorneys' Fees. In any dispute hereunder, or in any action to
enforce or interpret this Lease, the prevailing party is entitled to recover
reasonable attorneys' fees from the losing party.

     23.14  Landlord's Access Landlord and its agents have the right to enter
the Premises at reasonable times and after reasonable notice for the purpose of
inspecting them, showing them to prospective purchasers, lenders, or lessees,
and making necessary or desirable alterations, repairs, improvements or
additions to the Premises or to the Building. Landlord may display ordinary "For
Sale" signs at any place or time except in windows of the Premises while Tenant
occupies the Premises. All of these rights may be exercised without rebate of
rent or liability to Tenant.

     23.15  Signs and Auctions. Tenant may not place any sign upon the Premises
without Landlord's prior written consent, except signs conforming to the rules
and regulations of the Building, and the Master Use Permit sign required by the
City of Seattle.

     23.16  Quiet Possession. Upon paying the rent and observing and performing
all of its covenants and conditions of this Lease, Tenant shall have quiet
possession of the Premises for the entire term subject to all of the provisions
of this Lease.

     23.17  Building Rules and Regulations. Tenant will abide by all reasonable
rules and regulations which Landlord may make from time to time for the
management, safety, care, and cleanliness of the Building and grounds, the
parking of vehicles and the preservation of good order as well as for the
convenience of other occupants and tenants of the Building provided Landlord
gives Tenant reasonable prior written notice thereof. Violation of any rules and
regulations is a material breach of this Lease. A copy of current rules and
regulations is attached to this Lease as Exhibit F, which Tenant hereby
approves. Future rules and regulations which Landlord may from time to time make
will be reasonable and will not deprive Tenant from use of the Premises as
contemplated by the Lease.

     23.18  Relationship of Parties. For the purpose of this Lease, the
relationship of the parties hereto is strictly that of landlord and tenant.
Landlord has no interest in the Tenant's enterprise and this Lease cannot be
construed as a joint venture or partnership. Tenant is not an agent or
representative of the Landlord for any purpose.

     23.19  Landlord's Representations. Landlord represents to Tenant that
Landlord is vested with a fee title interest in the Building and the parking
spaces located in the Building and has the power and authority to execute this
Lease; that there are no mechanics or materialmen's liens affecting the Building
or the Premises; and that the Building has a B-2 occupancy classification.

24.  SPECIAL PROVISIONS

     24.01  Medical and Hazardous Waste and Materials. Tenant shall not dispose
of or otherwise allow the improper or illegal release of any medical waste or
hazardous waste or materials in, on or under the leased Premises, or any
adjacent property, or in any improvements placed on the Leased Premises. Tenant
shall comply at all times with all statutes, regulations and ordinances, and
with all orders, decrees or judgments of governmental authorities or courts
having jurisdiction, relating to the use, collection, treatment, disposal,
storage, control, removal or cleanup of medical waste and hazardous waste or
materials in, on or under the leased Premises or any adjacent property, or
incorporated in any improvements, at Tenant's sole expense.

After notice to Tenant and a reasonable opportunity for Tenant to effect such
compliance, Landlord may, but is not obligated to, enter upon the leased
Premises and take such actions and incur such costs and expenses to effect such
compliance as it reasonably deems advisable to protect its interest in the
leased Premises; provided however, that Landlord shall not be obligated to give
Tenant notice and an opportunity to effect such compliance if (1) such delay
might result in material adverse harm to Landlord or the leased Premises, (2)
Tenant has already had actual knowledge of the situation and a reasonable
opportunity to effect such compliance, or (3) an emergency exists. Whether or
not Tenant has actual knowledge of the release of hazardous waste or materials
on the Premises or any adjacent property as the result of Tenant's use of the
leased Premises, Tenant shall reimburse Landlord for the full amount of all
costs and expenses reasonably incurred by Landlord in connection with such
compliance activities, and such obligation shall continue even after the
termination of this Lease. Tenant shall notify Landlord immediately of any
release of any hazardous waste or materials or improper release of any medical
waste or materials on the leased Premises or in the Building.

Tenant shall indemnify and hold Landlord harmless against any and all losses,
liabilities, suits, obligations, fines, damages, judgments, penalties, claims,
charges, cleanup costs, remedial actions, costs and expenses (including, without
limitation, attorneys' fees and disbursements) which may be imposed on, incurred
or paid by, or asserted against Landlord or the Premises by reason of, or in
connection with (1) any misrepresentation, breach of warranty or other default
by Tenant under this paragraph, or (2) the acts or omissions of Tenant, or any
subtenant or other person for whom Tenant would otherwise be liable, resulting
in the release of any medical waste or hazardous waste or materials or the
violation of any law, rule, regulation or order pertaining to medical waste or
hazardous waste or materials.

Landlord represents and warrants to Tenant that to the best of Landlord's
knowledge Landlord has not received any notification from any governmental
agency indicating that the Premises, the Building or the real property upon
which the Building is located is or may be targeted for a federal or state
superfund
<PAGE>

cleanup and, except as described in the next sentence, Landlord has no knowledge
that the Premises, the Building or the real property upon which the Building is
located is contaminated with any hazardous wastes or materials. Landlord hereby
discloses and Tenant acknowledges that certain areas of the basement contained
small amounts of hydraulic fluid and sludge contaminated with elevated
concentrations of TPH and metals, and said fluid and sludge were removed and
disposed of in accordance with applicable regulations. Landlord has obtained and
supplied to Tenant an environmental assessment report on the Building. Landlord
agrees to indemnify and hold Tenant harmless from and against any and all loss,
damage, claims, penalties, liability, suits, costs and expenses (including,
without limitation, reasonable attorneys' fees) and also including, without
limitation, costs of remedial action or cleanup, suffered or incurred by Tenant
arising out of or related to any release or presence of hazardous wastes or
materials on, under or in the Premises, the Building or the real property upon
which the Building is located, unless such release or presence is due to the
acts or omissions of Tenant, its agents and employees. The term "hazardous
wastes or materials" means any substance, waste or material defined as
hazardous, toxic or dangerous by any federal, state or local statute rule,
ordinance requirement or regulation now or hereafter in effect, and shall
specifically include asbestos-- containing materials, PCBs and petroleum or
hydrocarbon products.

     24.02.  Right of First Opportunity to Lease. At all times during the term
of this Lease and any renewal terms, Tenant shall have the right of first
opportunity to lease any space which becomes available in the Building. Tenant
shall be informed in writing of space coming available when Landlord learns of
upcoming vacancies in the Building. In addition, prior to accepting an offer to
lease from a prospective tenant ("Third--Party Offer"), Landlord shall deliver
to Tenant notification of the availability of the space Landlord intends to
lease. Tenant shall have seven (7) business days after Landlord delivers such
notification to deliver written notice to Landlord that Tenant will lease the
space offered.

If Tenant fails to deliver said notice, Tenant's right of first opportunity
shall terminate as to that space until it once again becomes available and
Landlord shall be free to enter into a lease of the space to the third party who
made the Third--Party Offer for a period of six (6) months from the date of the
notice to Tenant. If the Landlord does not consummate a lease with the third
party within said six (6) month period, Tenant's right of first opportunity as
to that space shall revive.

If Tenant delivers notice of acceptance to Landlord within the required seven
(7) day period, Tenant shall, commencing with the first day of the month which
is three months from the date the existing tenant vacates the space, lease the
offered space on the same terms and conditions then in effect under this Lease.
The rental rate shall be the rate paid under this Lease plus the amount of
Operating Costs and Expenses paid on a square footage basis at the time of
commencement of the lease on the offered space. Landlord shall provide Tenant
with a Tenant improvement allowance as provided in paragraph 11.05.
<PAGE>

     24.03  Limitations in New Leases. During the initial term of this Lease
(years one through six only), any new leases of space in the Building entered
into by Landlord, (including any leases entered into following Tenant's failure
to exercise its right of first opportunity to lease as provided in paragraph
24.02 above), shall be limited to a maximum term of six (6) years and shall give
Landlord the right to terminate such leases effective as of the thirty-seventh
month after the commencement dates of such leases in order to provide Tenant the
opportunity to expand into the space leased to other tenants thirty--six (36)
months after the commencement dates of the leases executed with other tenants.
Landlord shall provide Tenant with nine (9) month's written notice of the
available space, and Tenant shall have twenty (20) days to deliver to Landlord
Tenant's notice of acceptance of the other Tenant's space. If Tenant declines
the space or fails to accept the space, Landlord shall be free to continue the
other tenantts occupancy of the space under the terms of the other tenant's
lease. If Tenant elects to lease the space, Tenant shall, on the first day of
the thirty-seventh month after the term of the third party lease term commenced,
lease the offered space on the same terms and conditions then in effect under
this Lease. The rental rate shall be the rate paid under this Lease plus the
amount of Operating Costs and Expenses paid on a square footage basis at the
time of commencement of the lease on the offered space. Landlord shall provide
Tenant with a Tenant improvement allowance as provided in paragraph 11.05.

     24.04  Expansion  Space  Undertaking. Tenant desires to lease additional
space in the Building currently occupied by a printing company (northeast corner
of ground floor), and restaurant and delicatessen (east side of second floor).
Upon written notice from Tenant that Tenant desires to lease such space,
Landlord agrees to in good faith attempt to negotiate an early cancellation of
the leases of such existing tenants. Landlord shall not be obligated to pay any
relocation costs or early termination costs nor take any action negatively
impacting the Building or Landlord's ability to lease or sell the Building in
connection with any negotiated cancellations. Landlord shall inform Tenant of
any demands for early termination compensation or lease concessions required by
any existing tenant and Tenant shall have the right to pay such compensation or
concession. In the event that any cancellation or relocations costs required by
the existing tenants are not approved by Tenant, Landlord's obligation to
attempt to obtain such early cancellations shall terminate. In the event of
vacation by the existing tenant or tenants, Tenant shall have One Hundred Twenty
