OVERVIEW
 
     Targeted Genetics is focused on the development of gene and cell therapies
for the treatment of certain acquired and inherited diseases. The Company is
developing a broad base of core technologies that it believes will allow it to
address a variety of such diseases. These technologies include proprietary viral
and non-viral gene delivery systems as well as novel techniques for cytotoxic T
lymphocyte ("CTL") immunotherapy. The Company is using its core technology
platform to develop potential products for the treatment of various genetic
disorders, cancer and infectious diseases.
 
     The Company believes that in the area of gene therapy, different disease
targets will require different methods of gene delivery, depending on the target
cell to be modified, the duration of gene expression required and the need for
in vivo or ex vivo delivery. Accordingly, the Company is developing multiple
gene delivery systems based on three different vector technologies:
adeno-associated viral ("AAV"), non-viral and retroviral. The Company believes
these systems may provide it with the flexibility necessary to develop gene
therapies for a broader range of diseases than would be possible using a single
gene delivery system.
 
     In the area of cell therapy, the Company's expertise with CTLs enables it
to isolate from patients and efficiently multiply antigen-specific CTLs, which
are immune cells that target and kill specific diseased cells ("Targeted CTLs").
This expertise forms the basis for a series of potential immunotherapies for the
treatment of infectious diseases and cancer. Targeted CTLs are based on the
Company's proprietary Rapid Expansion Method ("REM") technology, which is used
to grow CTLs ex vivo prior to infusion into the patient. The Company has
demonstrated that REM enables it to grow billions of CTLs from individual cloned
cells over several weeks, while preserving the cells' specific disease-fighting
capabilities.
 
     Targeted Genetics is currently conducting or planning a number of clinical
trials based on its diversified technology platform, as shown in the following
table.

     In addition to the product development programs summarized above, the
Company is performing research oriented toward identifying promising new
applications of its technology base. Also, the Company is collaborating with
certain academic researchers who are using its retroviral vectors in Phase I
clinical trials focused on Gaucher disease, melanoma and HIV infection.
 
PRODUCT DEVELOPMENT PROGRAMS
 
  CYSTIC FIBROSIS
 
     Cystic fibrosis is the most common single-gene deficiency affecting the
Caucasian population, afflicting approximately 30,000 people in the United
States and 60,000 people worldwide. The disease is caused by a dysfunctional
cystic fibrosis transmembrane regulator ("CFTR") gene, which results in a
build-up of mucus in the lungs, infections and early death. Current treatments
for cystic fibrosis offer only symptomatic relief and cannot cure or halt the
progression of the disease.
 
     tgAAV-CFTR. Based on preclinical findings by the Company and its scientific
collaborators, the Company believes that the persistence of expression and lack
of toxicity observed with its AAV-based gene delivery vector potentially make it
better suited than other types of vectors for delivery of the CFTR gene to the
lung. In preclinical studies in rabbits, the Company and its collaborators at
The Johns Hopkins University ("Johns Hopkins") were able to detect expression of
the CFTR gene in the lung for periods of up to six months with no observed side
effects. These results were confirmed in similar studies in rhesus monkeys, in
which gene transfer occurred in up to 50% of target airway cells, and gene
expression, which was confirmed in all animals, persisted for up to six months.
Based on these preclinical data, the Company began two clinical trials in late
1995 to evaluate the safety and feasibility of in vivo gene therapy for the
treatment of cystic fibrosis by direct delivery of the CFTR gene using an AAV
vector. The Company's AAV-CFTR product ("tgAAV-CFTR") has been granted orphan
drug status by the United States Food and Drug Administration (the "FDA").
 
     The first clinical trial, which began in November 1995, is a Phase I
clinical trial at Johns Hopkins and the University of Florida in which
tgAAV-CFTR is being delivered to the nose and lung of adult cystic fibrosis
patients having mild lung disease. The trial is designed as an interpatient dose
escalation trial and will enroll a total of 16 patients. Two patients are being
treated at each of eight escalating dose levels. The tgAAV-CFTR is administered
in an open-label single dose to the right lower lobe of the lung via
bronchoscopy. Additionally, each patient is randomized to receive a single dose
of tgAAV-CFTR administered to one nostril and a placebo to the other. Patients
are monitored for, among other things, safety and assessment of gene transfer
and expression. The nasal administration is intended to determine if physiologic
measurement of CFTR function can be obtained in the nasal epithelium. The
Company expects to complete this clinical trial in early 1997. If the results of
the trial confirm the Company's preclinical findings of safety and gene
transfer, the Company intends to conduct a subsequent clinical trial later in
1997 involving aerosol delivery of tgAAV-CFTR to the whole lung. The Company is
currently developing an aerosol formulation for testing in a toxicology study
prior to beginning the clinical trial.

<PAGE>   5
 
     A second clinical trial began in December 1995 at Stanford University. This
trial was designed as a Phase I/II trial, pursuant to which tgAAV-CFTR is
administered to the maxillary sinuses of cystic fibrosis patients with chronic
sinusitis. The Phase I part of this trial, designed as a dose escalation study,
has been completed. A total of ten patients were enrolled, and 15 sinuses were
treated, in five cohorts receiving escalating doses. The results of the trial
indicate that tgAAV-CFTR is safe and well tolerated with no resulting
inflammatory response or other side effects, even after repeat delivery.
Furthermore, administration of tgAAV-CFTR resulted in consistent gene transfer
and, in one patient, persistence of the gene for at least 70 days after
treatment. Additionally, the dose level was established for the Phase II part of
the trial, in which up to 50 patients will receive tgAAV-CFTR in one sinus and a
placebo in the other. Patients in the Phase II trial will be monitored to assess
the ability of tgAAV-CFTR to prevent the relapse of chronic sinusitis. The Phase
II part of the trial began in February 1997.
 
  Cancer
 
     Cancer is the second leading cause of death in the United States, with over
one million new cases diagnosed each year. The Company's primary approach to the
treatment of cancer utilizes a proprietary non-viral delivery system to deliver
in vivo an E1A tumor suppressor gene to cancer cells. A second approach involves
the use of Targeted CTLs to enhance the immune system's natural ability to
eliminate cancer cells selectively.
 
     tgDCC-E1A. Cancer arises when the genetic pathways that control normal cell
growth and division are disrupted. Certain of these pathways are regulated by
cellular oncogenes or tumor suppressor genes. Cancer may result from the
structural alteration and abnormal expression of cellular oncogenes or from
mutation or deletion of tumor suppressor genes. Some viruses have evolved genes
that may mimic functions normally exhibited by cellular genes. One such example
is the E1A gene of the adenovirus type 5. The E1A gene was shown by Dr. Mien
Chie Hung, in experiments conducted at University of Texas M.D. Anderson Cancer
Center ("M.D. Anderson"), to function as a suppressor of the HER-2/neu oncogene,
which is known to be overexpressed in certain cancers. The Company has worldwide
rights to the use of the E1A gene as a tumor suppressor.
 
     Overexpression of the HER-2/neu oncogene occurs in approximately 30% of
patients in a number of cancers, including ovarian, breast, head and neck,
stomach, pancreatic, liver, cervical and prostate cancer, and has been
associated with enhanced metastatic potential, drug resistance and poor survival
rates. The E1A tumor suppressor gene has been shown to inhibit the
overexpression of the HER-2/neu oncogene in certain tumor cells in vitro. In
addition, in preclinical mouse studies E1A was shown to inhibit the
intraperitoneal growth of ovarian cancer cells that were overexpressing the
HER-2/neu oncogene, and to increase significantly the long-term survival of the
mice.
 
     Other research has suggested that E1A may have other tumor suppression
activity beyond the inhibition of HER2/neu expression. Preclinical in vitro
experiments have shown that E1A, when introduced to a variety of tumor cell
lines, is capable of altering tumor cells such that they appear to have
characteristics of normal cells. Furthermore, in vivo mouse studies involving
tumor cells not overexpressing HER-2/neu showed reduced tumor growth rates with
the administration of E1A versus the same tumor cells without E1A. E1A has also
been shown in preclinical studies to sensitize tumor cells to killing by certain
chemotherapeutic agents.
 
     The Company's E1A product ("tgDCC-E1A") is a formulation that combines the
E1A tumor suppressor gene with the Company's proprietary non-viral gene delivery
system based on the cationic lipid DC cholesterol ("DC Chol"). In the Company's
first Phase I clinical trial, which began in July 1996 at M.D. Anderson, 12 to
24 patients with ovarian cancer and 12 to 24 patients with breast cancer having
tumors that overexpress the HER-2/neu oncogene are administered weekly doses of
tgDCC-E1A for up to six months. This trial is being conducted as an
interpatient, escalating dose study with doses of tgDCC-E1A delivered
intraperitoneally in the ovarian cancer patients and intrapleurally in the
breast cancer patients. The objectives of the trial are to assess safety, levels
of gene transfer and expression and tumor response. Two additional sites have
been added to the study and it is expected that this clinical trial will be
completed in 1997.
 
                                        5
<PAGE>   6
 
     A second Phase I clinical trial is expected to begin in early 1997 at M.D.
Anderson, in which 12 to 24 patients with nonoperable primary head or neck
tumors or metastatic breast or lung tumors are administered weekly doses of
tgDCC-E1A, injected directly into the patient tumor, for up to two months. The
trial is being conducted as an interpatient escalating dose study with two
patients in each cohort. The objectives of the trial are to assess safety,
levels of gene transfer and expression and tumor response. Two additional sites
are being added to the study and it is expected that this clinical trial will be
completed by the end of 1997.
 
     In 1996, the Company entered into a license, research and marketing
agreement with Laboratoires Fournier S.C.A. ("Fournier") under which Fournier
received exclusive rights to develop and commercialize tgDCC-E1A in Europe. See
"Research and Development Collaborations."
 
     Targeted CTLs. The Company has conducted certain preclinical experiments
directed to the isolation and ex vivo multiplication of CTLs specific to colon
tumor cells. Also, in conjunction with a recently completed
investigator-sponsored melanoma tumor vaccine clinical trial, the Company has
shown that it can generate CTLs specific to melanoma tumor cells, multiply these
CTLs in the REM process and use them to kill cancer cells in vitro. Based on
these and other experiments, the Company believes that a potentially effective
cancer therapy may be developed based on the infusion of large numbers of
Targeted CTLs that kill specific tumor cells. However, due to resource
constraints and also due to the Company's growing commitment to cancer therapy
using the E1A tumor suppressor, the Company will not pursue clinical trials of
Targeted CTLs for cancer unless a corporate collaboration in this area is
completed.
 
  INFECTIOUS DISEASES
 
     Human Immunodeficiency Virus ("HIV"). HIV is a retrovirus that is the cause
of AIDS, a condition that is characterized by loss of CD4 cells and progressive
immunologic impairment and death. According to the Centers for Disease Control
and Prevention, approximately one million people in the United States have been
infected with HIV. The World Health Organization estimates that approximately 17
million people worldwide have been infected with HIV and projects that the
worldwide incidence of HIV infection will grow to 30 million to 40 million
people by the end of the century.
 
     The Company and certain other researchers believe that the key to
successful long-term treatment of HIV infection may lie in manipulating and
harnessing the cell-mediated arm of the immune response. Researchers have found
that HIV-infected people who remain symptom-free for prolonged periods have high
levels of CTLs that suppress viral proliferation in CD4 cells. The Company
believes that the provision of large quantities of cloned HIV-specific CTLs may
provide a means of allowing HIV-infected people to maintain an effective immune
response, thereby preventing progression to AIDS.
 
     In early 1996, the Company began a Phase I clinical trial at the Fred
Hutchinson Cancer Research Center (the "Hutchinson Center") in which up to eight
HIV-infected patients are being administered five escalating doses of Targeted
CTLs specific to the HIV gag protein. The first three doses will consist of
unmarked cells and the last two will consist of cells modified with a retroviral
vector containing a marker gene. Patients in the trial will be monitored for
safety, persistence of the infused Targeted CTLs and changes in viral burden.
This trial is expected to be completed in 1997.
 
     Hepatitis B. Hepatitis B virus ("HBV") is a disease of global significance,
with over 300 million carriers worldwide. HBV is the cause of up to 80% of cases
of primary liver cancer. Over 75% of the chronic carriers of HBV are in Asia. It
is estimated that 200,000 to 300,000 HBV infections occur annually in the United
States and that chronic infection develops in approximately 10% of those cases.
 
     During acute HBV infection most patients develop a strong immune response
that is capable of clearing the virus. In contrast, the CTL response to HBV is
usually not detectable in chronically infected patients. The lack of core
specific CTL response may contribute to failure of virus elimination resulting
in chronic inflammation. Thus, the Company believes that restoring the immune
response by administering Targeted CTLs specific for HBV may provide an
effective means to treat patients with this chronic disease.
 
     In 1997, the Company plans to take the necessary steps to adapt its
Targeted CTL technology to the treatment of HBV in preparation for a preclinical
study in which chimpanzees infected with HBV will be
 
                                        6
<PAGE>   7
 
administered Targeted CTLs. The objective of the study, expected to begin in
late 1997, is to establish safety of the therapy and, potentially, obtain proof
of concept that HBV-specific Targeted CTLs may be promising as a treatment for
humans infected with HBV.
 
CORE TECHNOLOGIES
 
     The Company is developing a broad range of core technologies that it
believes will allow it to address issues specific to a variety of diseases. The
Company believes that in the area of gene therapy, different disease targets
will require different methods of gene delivery, depending on the target cell to
be modified, the duration of gene expression required and the need for in vivo
or ex vivo delivery. Accordingly, the Company is developing multiple gene
delivery systems based on three different vector technologies: AAV, non-viral
and retroviral. In certain treatments, for which in vivo modification of slowly
dividing or nondividing target cells is required or preferred, such as
modification of lung cells to treat cystic fibrosis, the Company is utilizing
its AAV vector technology. The Company uses its retroviral vector technology in
therapeutic areas where permanent modification of rapidly dividing cells is
necessary. In therapeutic indications where the use of AAV and retroviral
vectors is not desirable or feasible, the Company is utilizing its non-viral
delivery systems. The Company believes that non-viral vectors may provide
greater flexibility relating to the size and sequence of transfered genes and
may also allow targeted delivery in vivo.
 
     In the area of cell therapy, the Company's expertise in isolating and
multiplying CTLs forms the basis for a series of potential immunotherapies.
 
  GENE THERAPY
 
     Overview. Gene therapy is an approach to the treatment and prevention of
genetic and acquired diseases that involves the insertion of 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. Proteins are
produced by cells 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 is
responsible for causing some diseases, including inherited diseases such as
cystic fibrosis and certain types of cancer. Gene therapy may be used to treat
such 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.
 
     A key factor in the progress of gene therapy is 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. Vectors may be
derived from either viral or non-viral 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), in which cells are
removed from the patient, genetically modified, and then reinfused into the
patient, or in vivo (inside the body), in which 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 application of
viral gene transfer to indications requiring long-term gene expression entails a
number of essential technical requirements, including the ability of the viral
vector to carry desired segments of genes, to transfer genes into a sufficient
number of target cells and to enable genes contained in the viral vector 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.
 
                                        7
<PAGE>   8
 
     Current non-viral 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; ionically binding negatively charged DNA to the surface
of cationic lipids which are positively charged prior to infusion; injecting
pure plasmid or "naked" DNA in an aqueous solution; and directing DNA to
receptors on target cells by combining the gene with protein carriers that are
taken up by the cell.
 
     AAV Vectors. Targeted Genetics and its scientific collaborators have
developed significant expertise with respect to the design and use of AAV
vectors in gene therapy. The Company believes that certain features of AAV
vectors make them particularly well suited for the treatment of a number of
diseases: (i) AAV has never been associated with causing any human disease; (ii)
AAV generally cannot replicate without the presence of a helper virus; (iii) AAV
vectors contain no viral genes that, if present, might produce unwanted immune
responses leading to side effects or reduced efficacy; (iv) unlike some other
types of viral systems, AAV vectors can introduce genes into nondividing or
slowly dividing cells, such as cells lining the airway of the lung; (v) AAV
vectors may persist in the host cell to provide relatively long-term expression;
and (vi) AAV vectors can be purified and concentrated, and thereby may allow for
more efficient manufacturing.
 
     The Company is building its proprietary position in AAV through the
development or acquisition of exclusive rights to inventions that (i) provide
important enhancements to AAV vectors; (ii) demonstrate novel approaches to the
use of AAV vectors for gene therapy; and (iii) establish new and improved
methods for large-scale production of AAV vectors. The Company has exclusive
rights from the National Institutes of Health (the "NIH") to an issued patent
for use of a novel AAV vector for cystic fibrosis.
 
     In addition to its development program for cystic fibrosis, the Company is
conducting research to assess the potential for delivery of genes to other
target cells using AAV vectors. To date, the Company has focused its efforts in
this area to cells of the cardiovascular system and the gastrointestinal tract.
With the Company's newly increased capacity to manufacture AAV vectors for
preclinical research purposes, it plans to examine the use of AAV vectors in
additional cell types, both internally, to the extent resources are available to
do so, and through academic collaborators.
 
     Non-Viral Vectors. The Company has exclusive rights to a significant body
of non-viral gene delivery technology based on the use of cationic lipids to
promote the uptake of DNA into cells. The Company believes that non-viral
vectors may have several characteristics that may make them particularly well
suited for the treatment of certain diseases, including (i) the ability to
target such vectors to a specific cell type; (ii) relative ease of manufacture;
and (iii) the ability to transfer relatively large segments of DNA in a single
vector. These non-viral vectors are formulated by complexing negatively charged
DNA with cationic lipids which are positively charged to promote DNA uptake by
cells. Such complexes appear to have good safety profiles and can be used in
vivo as well as ex vivo. For in vivo use, these complexes can potentially be
delivered topically, intravenously, intraperitoneally, intrapleurally or by
aerosol.
 
     The Company intends to develop a series of these non-viral delivery systems
originated by Dr. Leaf Huang of the University of Pittsburgh. His original DC
Chol system, which appears to have a favorable clinical toxicity profile, was
used in two clinical trials by unaffiliated investigators prior to the Company
using it in its tgDCC-E1A cancer clinical trials. The Company has acquired an
exclusive license to an issued U.S. patent for the original DC Chol system for
the treatment of certain cancers, including, among others, breast, ovarian and
lung cancers. Dr. Huang is developing a series of non-viral delivery systems for
which the Company has obtained exclusive worldwide rights in the field of gene
therapy from the University of Pittsburgh. One type of system under development
employs additional analogs of DC Chol that may have a more favorable toxicity
profile. In another system, the DNA is condensed into particles of defined size
that have gene transfer efficiency that is fifty- to eighty-fold higher than the
original DC Chol system. An alternate version of this system is being developed
that includes specific ligands to enhance delivery to specific target cells and
to increase stability when delivered intravenously. An additional system being
developed also has increased efficiency of gene transduction and higher
stability in serum for intravenous delivery. Specific formulations will be
chosen for various applications based on the type of target cell, desired mode
of administration and biology of the disease.

     Retroviral Vectors. The Company uses retroviral vectors to modify T cells
and stem cells. These cells multiply to generate large numbers of progeny
(daughter) cells and are well suited as targets for retroviral vectors that can
modify only rapidly dividing cells. The Company believes that it has positioned
itself at the forefront of retroviral gene delivery technology through its
exclusive relationship with Dr. A. Dusty Miller, a leader in the development of
packaging cell lines for retroviral vectors. One of Dr. Miller's more recent
inventions in this area is a new type of retroviral vector packaging cell line
called PG13, which the Company has licensed exclusively from the Hutchinson
Center. Vectors produced in this cell line have been shown to have improved
efficiency for ex vivo transfer of genes to human blood cells such as T cells
and stem cells.
 
     To date, the Company's internal efforts with retroviral vectors have been
primarily oriented toward improvements in the design, manufacture and methods of
using such vectors for gene transfer and expression. Additionally, the Company
has manufactured retroviral vectors for several investigator-sponsored clinical
trials. In one such clinical trial, peripheral blood stem cells were reinfused
into Gaucher disease patients after ex vivo transduction with the Company's
retroviral vectors containing the GC gene. The results of this clinical trial
have confirmed the Company's belief that current technology and know how related
to stem cell gene therapy must be improved in order to provide the increased
level of gene transfer and expression necessary to result in an effective
therapeutic product. Although the Company believes that retroviral vectors show
long-term promise for the ex vivo delivery of therapeutic genes, the Company's
only current effort internally in the area of retroviral vectors relates to the
process used to generate Targeted CTLs. Given this low level of internal
development activity related to retroviral vectors, the Company is pursuing
licensing arrangements for use of the PG13 vector for applications outside the
Company's interests.
 
  TARGETED CTLS
 
     Overview. The immune system is the body's major defense mechanism
responsible for protecting against disease. It functions through a complex
interplay of components and allows the body to detect foreign agents and thereby
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. Lymphocytes comprise two major classes: B cells, which produce
antibodies that mediate humoral immunity, and T cells, which direct
cell-mediated immunity.
 
     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, i.e., they individually recognize and bind to only a single,
specific antigen. Furthermore, only in the presence of CD4 helper cells do these
specific CTLs proliferate to produce the large population of antigen-specific
CTLs required to elicit an effective immune response.
 
     In some disease states, the immune system fails to mount or maintain an
effective immune response. For infectious diseases and cancer, it is believed
such failure may be associated with an inadequate CTL response. For example, HIV
infects and kills CD4 cells, which leads to subsequent loss of CTL function and,
thus, to destruction of the immune system by the virus.
 
     Targeted CTL Cell Therapy. Targeted Genetics is working to develop a highly
targeted form of cell therapy, which is intended to produce a powerful,
disease-specific immune response through the infusion of large numbers of
antigen-specific CTLs. In the Company's 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.
 
     The Company believes that its Targeted CTL program represents an
improvement over other approaches to immunotherapy because it is based on
cloned, antigen-specific CTLs. The Company believes that Targeted CTLs may be
more effective than other immunotherapy approaches because virtually all of the
reinfused cells will be CTLs targeting the specific diseased cells. The Company
also believes that the safety and side effect
 
                                        9
<PAGE>   10
 
profile may be improved over other immunotherapy approaches because of the
uniformity and consistency of the reinfused cells.
 
     The Company's focus on Targeted CTLs originated from research conducted by
its collaborators at the Hutchinson Center, Drs. Philip Greenberg and Stanley
Riddell. These researchers conducted a Phase I clinical trial to evaluate the
safety of infusing donor-derived, CMV-specific CTLs to bone marrow transplant
patients, and the potential of this approach for providing an immune response
against CMV during the short period in which transplant patients have a high
probability of developing CMV. This trial, which was published in The New
England Journal of Medicine in October 1995, was the first clinical trial in
which cloned, antigen-specific CTLs had been used. None of the 14 patients
receiving the CTLs developed CMV viremia or disease.
 
     Rapid Expansion Method. The Targeted CTL program is based on the Company's
proprietary REM technology, which is used to rapidly grow CTLs prior to infusion
into the patient. REM represents a significant improvement over other methods of
multiplying T cell clones. Using REM, CTL clones can be multiplied over a
thousandfold in less than two weeks. The Company has demonstrated that REM
enables it to grow billions of CTLs from individual cloned cells over several
weeks, while preserving the cells' disease-fighting capabilities in vitro. The
Company has seen consistent results from REM in both CD8 and CD4 T cells and for
all disease specificities tested to date. The Company has shown that REM is
effective for growing Targeted CTLs specific for HIV, CMV, malignant melanoma
and prostate tumor peptides. The Company has filed patent applications, on a
worldwide basis, relating to the original REM process and to subsequent process
improvements.
 
RESEARCH AND DEVELOPMENT COLLABORATIONS
 
  LABORATOIRES FOURNIER S.C.A.
 
     In May 1996, the Company and Fournier entered into a license, research and
marketing agreement under which Fournier received exclusive rights to develop
and commercialize in Europe tgDCC-E1A and any other product candidates based on
the E1A tumor suppressor gene and developed pursuant to the agreement. Fournier
has agreed to coordinate development of tgDCC-E1A in Europe by conducting
clinical trials, preparing and filing submissions for regulatory approval in its
territory and paying all associated costs, while the Company has corresponding
responsibilities with respect to development and commercialization in the United
States.
 
     Fournier has paid a $5 million upfront license fee and $1.5 million of
milestone payments through the end of 1996. The agreement provides that Fournier
will make additional milestone payments to the Company upon the achievement of
specified goals by Fournier or the Company and royalties on sales of resulting
products, if any. In addition, if the parties are able to negotiate a mutually
acceptable supply agreement, the Company will be entitled to manufacture
products for Fournier in return for manufacturing fees. Pursuant to the
agreement, the Company has agreed to indemnify Fournier with respect to claims
incurred as a result of the manufacture, supply or sale of tgDCC-E1A. The
agreement may be terminated if the parties mutually agree on or about the second
anniversary of the agreement that the results of the collaboration are
unsatisfactory.
 
  PASTEUR MERIEUX
 
     In December 1995, the Company entered into an agreement with Pasteur
Merieux pursuant to which Pasteur Merieux was granted an exclusive worldwide
license and sublicense to certain technology and patent rights relating to DC
Chol as an immunoadjuvant in traditional vaccines. In consideration of such
grant, Pasteur Merieux paid a process development fee and an upfront license
fee. In addition, the Company may receive milestone payments upon realization of
certain benchmarks and a royalty on sales of the products, if any, incorporating
the underlying technology.

RELATIONSHIP WITH IMMUNEX CORPORATION
 
     Targeted Genetics was formed in 1989 as a subsidiary of Immunex Corporation
("Immunex"), a biotechnology company developing immunoregulatory proteins as
therapeutics. In February 1992, Targeted Genetics and Immunex entered into a
technology license agreement. In exchange for shares of Preferred Stock, which
were converted into 1,920,000 shares of Common Stock at the time of the
Company's initial public offering, Immunex granted a worldwide, exclusive field
of use license to Targeted Genetics for certain Immunex proprietary technology
specifically applicable to Targeted Genetics' gene therapy business. The
technology transferred from Immunex to Targeted Genetics 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, until February 1999, the Company
has the option to acquire a nonexclusive, worldwide, fully paid royalty-free
license (and in certain cases an opportunity to negotiate the conversion of a
nonexclusive license into an exclusive license) for certain additional
technology relating to Targeted Genetics' gene therapy business. Targeted
Genetics granted to Immunex a right of first offer and a 30-day right of first
refusal on technology the Company intends to out-license that is based on
Immunex technology. The Company may accept or reject any offers made by Immunex
under such rights. Immunex currently owns approximately 13% of the Company's
outstanding common stock.
 
PATENTS AND PROPRIETARY RIGHTS
 
     Patents and licenses are important to the Company's business. The Company's
policy is to file patent applications to protect technology, inventions and
improvements to inventions that are considered important to the development of
its business. The Company also relies on trade secrets, know how, continuing
technological innovations and licensing opportunities to develop and maintain
its competitive position. To date, the Company has filed or exclusively licensed
39 patent applications relating to its product and technology development
programs with the United States Patent and Trademark Office (the "USPTO"), as
well as foreign counterparts of certain of these applications in Europe, Japan
and certain other countries. Of these patent applications, 5 patents have been
issued or allowed by the USPTO.
 
     In addition to the intellectual property that Targeted Genetics owns or has
exclusively licensed, the Company has licensed several issued and pending
patents that relate to its development programs 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 NIH and the University of Florida Research Foundation.
In addition, the Company has acquired nonexclusive rights to the cystic fibrosis
gene being delivered in an AAV vector.
 
     The patent positions of pharmaceutical and biotechnology firms, including
the Company, are uncertain and involve complex legal and factual questions for
which important legal principles are largely unresolved, particularly in regard
to human therapeutic uses. In addition, the coverage claimed in a patent
application can be significantly reduced before a patent is issued.
Consequently, the Company does 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 will be circumvented or
invalidated. Since patent applications in the United States are maintained in
secrecy until patents issue and patent applications in certain 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, the Company cannot be certain that it or any licensor
was the first creator of inventions covered by pending patent applications or
that it or such licensor was the first to file patent applications for such
inventions. Moreover, the Company is currently involved in one patent
interference proceeding declared by the USPTO to determine priority of invention
relating to certain components that may be useful in retroviral vectors and may
have to participate in additional interference proceedings. Although the Company
does not anticipate that material expenditures will be made in connection with
such proceedings, participation could result in substantial cost to the Company,
even if the eventual outcome were favorable to it. In addition, although the
Company believes that the technology which is the subject of the current patent
interference proceeding is not material to its current product development
programs, there can be no assurance that such technology will not become
material in the future. If the outcome of the current or any additional
interference proceeding were unfavorable, the Company may be
 
                                       11
<PAGE>   12
 
unable to obtain rights to the invention involved. There can be no assurance
that the Company's patents, if issued, would be held valid or enforceable by a
court or that a competitor's technology or product would be found to infringe
such patents. Litigation, which could result in substantial cost to the Company,
may be necessary to enforce the Company's patents or to determine the scope and
validity of other parties' proprietary rights. If the outcome of any such
litigation were adverse, the Company's business could be materially adversely
affected. The Company is unable to predict how courts will resolve any future
issues relating to the validity and scope of its 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 the Company's
business. Some of these technologies, applications or patents may conflict with
the Company's technologies or patent applications. Such conflict could limit the
scope of the patents, if any, that the Company may be able to obtain or result
in denial of the Company's patent applications. In addition, if patents that
cover the Company's activities are issued to other companies, there can be no
assurance that the Company would be able to develop or obtain alternative
technology.
 
     Furthermore, as the biotechnology industry expands and more patents are
issued, the risk increases that the Company's processes and potential products
may give rise to claims that they infringe the patents of others. Such other
persons could bring legal actions against the Company claiming damages and
seeking to enjoin clinical testing, manufacturing and marketing of the affected
product or use of the affected process. Litigation may be necessary to enforce
patents issued to the Company, to protect trade secrets or know how owned by the
Company or to determine the enforceability, scope and validity of proprietary
rights of others. If the Company becomes involved in such litigation, it could
result in substantial expense to the Company and significant diversion of effort
by the Company's technical and management personnel. If there were an adverse
outcome of any such litigation, the Company's business could be materially
adversely affected. In addition to any potential liability for significant
damages, the Company 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 licensing arrangement may be substantial and could include
ongoing royalties. There can be no assurance that any license required under any
such patent would be made available to the Company on acceptable terms, if at
all.
 
     In addition to patent protection, the Company relies upon trade secret
protection for its confidential and proprietary information. There can be no
assurance that others will not independently develop substantially equivalent
proprietary information and techniques or otherwise gain access to the Company's
trade secrets or disclose such technology. To protect its trade secrets, the
Company requires its employees, consultants, scientific advisors and parties to
collaborative agreements to execute confidentiality agreements upon the
commencement of employment, the consulting relationship or the collaboration
with the Company. In the case of employees, the agreements also provide that all
inventions resulting from work performed by them while in the employ of the
Company will be the exclusive property of the Company. There can be no
assurance, however, that these agreements will provide meaningful protection of
the Company's trade secrets or adequate remedies in the event of unauthorized
use or disclosure of such information.
 
COMPETITION
 
     The Company is aware of a number of companies and institutions that are
developing or considering the development of potential gene therapy and cell
therapy treatments, including early-stage gene therapy companies, fully
integrated pharmaceutical companies, universities, research institutions,
governmental agencies and other healthcare providers. In addition, the Company's
potential products will be required to compete with existing pharmaceutical
products, or products developed in the future, that are based on established
technologies. Many of the Company's 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 distribution than the Company. In addition, the
competitive positions of other early-stage companies may be enhanced
significantly through their collaborative arrangements with large pharmaceutical
companies or academic institutions. The Company's competitors may succeed in
developing,
 
                                       12
<PAGE>   13
 
obtaining patent protection for, receiving FDA and other regulatory approvals
for, or commercializing products more rapidly than the Company. If the Company
is successful in commercializing its products, it will be required to compete
with respect to manufacturing efficiency and marketing capabilities, areas in
which it has no experience. The Company also competes with others in acquiring
products or technology from research institutions or universities. The Company's
competitors may develop new technologies and products that are available for
sale prior to the Company's potential products or that are more effective than
the Company's potential products. In addition, competitive products may be
manufactured and marketed more successfully than the Company's potential
products. Such developments could render the Company's potential products less
competitive or obsolete, and could have a material adverse effect on the
Company's business, financial condition and results of operations.
 
GOVERNMENTAL REGULATION
 
     All of the Company's potential products will require regulatory approval by
U.S. and foreign governmental agencies prior to commercialization in such
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 the Company's potential products. Similar requirements are
imposed by foreign regulators. In some cases, state requirements 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
ever, and involve substantial expenditures. Moreover, ongoing compliance with
applicable requirements can entail the expenditure of substantial resources.
Difficulties or unanticipated costs may be encountered by the Company in its
efforts to secure necessary governmental approvals, which could delay or
preclude the Company from marketing its 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 efficacy. 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 ("IND"), which must be reviewed and cleared by the FDA before
proposed clinical testing can begin. Clinical trials must be conducted in
accordance with Good Clinical Practices 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 IND. The FDA's review or approval of a study protocol does not
necessarily mean that, if the trial is successful, it will constitute proof of
efficacy or safety. Further, each clinical trial must be approved by and
conducted under the auspices of an independent Institutional Review Board
("IRB") at the institution at which the trial will be conducted. The IRB will
consider, among other things, ethical factors, the safety of human subjects and
the possible liability of the institution. The IRB is also responsible for
continuing oversight of the approved protocols in active trials. An IRB may
require changes in a protocol, and there can be no assurance that an IRB will
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 are conducted with 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 determine preliminary efficacy and
optimal dosages and to obtain expanded evidence of safety. In Phase III,
large-scale, multicenter, comparative clinical trials are conducted with
patients afflicted with a 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 an unwarranted risk is presented to patients. Because gene
therapy products are a new category of therapeutics, there can be no assurance
as to the length of the clinical
 
                                       13
<PAGE>   14
 
trial period or the number of patients the FDA will require to be enrolled in
the clinical trials in order to establish to its satisfaction the safety and
efficacy of such products.
 
     FDA marketing approval must be obtained after completion of clinical trials
of a new product. The Company expects that its products will be regulated as
biologic drugs. According to the FDA's 1993 notice outlining its regulatory
approach to somatic and gene therapy products, these products are also subject
to the drug provisions of the Federal Food, Drug and Cosmetic Act. This notice
also stated, however, that the FDA's regulatory approach may evolve as
scientific knowledge increases in the area of somatic and gene therapy. Current
regulations relating to biologic drugs will require the Company to submit to the
FDA both a Product License Application ("PLA") and an Establishment License
Application ("ELA"), which must be approved by the FDA before commercial
marketing is permitted. The PLA/ELA must include results of product development
activities, preclinical studies and clinical trials, in addition to detailed
manufacturing information. FDA approval of PLA/ELAs generally takes at least one
year. The process may take substantially longer if the FDA has questions or
concerns about a product. The FDA may also request additional data relating to
safety or efficacy. Notwithstanding the submission of relevant data, the FDA may
ultimately decide that a PLA/ELA does not satisfy its regulatory criteria for
approval. The FDA may also modify the scope of the desired claims or require the
addition of warnings or other safety-related information and require additional
clinical tests following approval to confirm product safety and efficacy (Phase
IV trials). Even if FDA regulatory clearances are obtained, a marketed product
is subject to continual review, and later discovery of previously unknown
problems or failure to comply with the applicable regulatory requirements may
result in restrictions on marketing a product or in withdrawal of the product
from the market, as well as possible civil or criminal sanctions.
 
     The FDA recently amended its regulations to eliminate the ELA requirement
for therapeutic DNA plasmid products, therapeutic synthetic peptide products of
40 or fewer amino acids, monoclonal antibody products for in vivo use, and
therapeutic recombinant DNA-derived products. Manufacturers of these products
will instead be required to submit a biologics license application, which will
include, among other information, nonclinical and clinical data demonstrating
that the manufactured product meets prescribed standards for safety, purity and
potency, and information pertaining to manufacturing methods. It is unclear
whether any of the Company's products will fall within the category of products
for which the ELA requirement has been eliminated, or what effect such
elimination may have on product development and FDA review.
 
     The FDA requires that manufacturers of a product comply with current Good
Manufacturing Practices ("cGMP") requirements, both as a condition of product
approval and on a continuing basis. In complying with cGMP requirements,
manufacturers must expend time, money and effort on a continuing basis in
production, record keeping and quality control. Manufacturing facilities are
subject to periodic inspections by the FDA to ensure compliance. Failure to pass
such inspections may subject the manufacturer to possible FDA action such as the
suspension of manufacturing, seizure of the product, withdrawal of approval or
other regulatory sanctions. The FDA may also require the manufacturer to recall
a product.
 
     In addition to regulations enforced by the FDA, the Company is 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. The Company's
research and development activities involve the controlled use of hazardous
materials, chemicals, biological materials and radioactive compounds. Although
the Company believes that its safety procedures for handling and disposing of
such materials comply with the standards prescribed by state and federal laws
and regulations, the risk of accidental contamination or injury from these
materials cannot be completely eliminated. In the event of such an accident, the
Company could be held liable for any resulting damages, and any such liability
could exceed the Company's resources.
 
HUMAN RESOURCES
 
     At December 31, 1996, Targeted Genetics had 88 employees; 69 of these
employees were directly involved in research and development, of whom 17 had
Ph.D. or M.D. degrees. A significant number of the
 
                                       14
<PAGE>   15
 
Company's management and professional employees have prior experience with other
biotechnology or pharmaceutical companies. The Company considers its relations
with its employees to be good.
 
     The Company's success will depend in large part on its ability to attract
and retain key employees and scientific advisors. Competition among
biotechnology and pharmaceutical companies for highly skilled scientific and
management personnel is intense. There can be no assurance that the Company will
be successful in retaining its existing personnel or advisors, or in attracting
additional qualified employees.
 
EXECUTIVE OFFICERS
 
     The following are the executive officers of Targeted Genetics who will
serve in the capacities noted until their successors are duly appointed and

FACTORS AFFECTING FORWARD-LOOKING INFORMATION
 
     Early Stage of Product Development, Technological Uncertainty. The Company
has no commercial products and all of its potential products are in research,
development or early-stage clinical trials. Prior to any commercial use, these
potential products will require significant additional research and development,
extensive clinical testing and regulatory approval. There can be no assurance
that the Company's efforts to develop, test and gain regulatory approval of its
potential products will be successful.
 
     History of Losses and Uncertainty of Future Results. Targeted Genetics is a
development stage company and has generated minimal revenues and significant net
losses since inception. The Company expects to incur substantial additional
losses over at least the next several years. To achieve profitable operations,
Targeted Genetics, alone or with corporate collaborative partners, must
successfully develop, manufacture, obtain regulatory approvals and market its
potential products. There can be no assurance that the Company's efforts in
these areas will be successful.
 
     Uncertainties Relating to Clinical Trials. Existing data on the safety and
efficacy of gene and cell therapy treatments are very limited. There can be no
assurance that clinical trials of the Company's potential products will
demonstrate safety and efficacy. Furthermore, there can be no assurance that the
Company will not encounter unacceptable side effects or other problems in
clinical trials of its potential products that will cause the Company to delay
or discontinue development of such products. The rate of completion of the
Company's clinical trials depends on, among other factors, the rate of patient
enrollment. Delays in patient enrollment may result in increased costs, delays
or termination of clinical trials.
 
     Need for Additional Capital. The Company expects negative cash flow from
operations to continue and to increase for the foreseeable future. The Company
will require substantial additional funds to continue the development and
commercialization of its potential products. Adequate funds, whether obtained
through financial markets or from collaborative or other arrangements with
corporate partners or other sources, may not be available when needed or may not
be available on terms favorable to the Company. If additional funds are raised
by issuing equity securities, dilution to existing shareholders may result. If
funding is insufficient at any time in the future, the Company may be required
to delay, scale back or eliminate some or all of its research and development
programs. Furthermore, if at any time the Company's funds are depleted, the
Company may be required to cease operations.
 
     Uncertainty of Patent Position and Proprietary Rights. The failure of the
Company or its licensors to obtain and maintain patent protection for the
Company's technology could have a material adverse effect on the Company. Patent
positions in the biotechnology field are highly uncertain and involve complex
legal, scientific and factual questions. There can be no assurance that any
patent application relating to the technology used by the Company will result in
a patent being issued or that, if issued, the patent will afford protection
against competitors. As the biotechnology industry expands and more patents are
issued, the risk increases that the Company's processes and potential products
may give rise to claims that they infringe the patents of others. If the Company
becomes involved in patent litigation, it could result in substantial expense to
the Company and significant diversion of effort by the Company's technical and
management personnel. In addition to any potential liability for significant
damages, the Company could be required to obtain a license to continue to
manufacture or market the affected product or use the affected process. There
can be no assurance that any license required under any such patent would be
made available to the Company on acceptable terms, if at all. The Company also
relies upon unpatented proprietary technology. There can be no assurance that
the Company can meaningfully protect its rights in such unpatented proprietary
technology. See "Business -- Patents and Proprietary Rights."
 
     Uncertainty of Governmental Regulatory Requirements; Lengthy Approval
Process. The process of obtaining regulatory approvals for clinical trials or
for the manufacturing or marketing of the Company's potential products is costly
and time-consuming and is subject to unanticipated delays. There can be no
assurance that the Company will be able to obtain the necessary regulatory
approvals for manufacturing or
 
                                       16
<PAGE>   17
 
marketing any of its product candidates. Even if regulatory approval of a
potential product is obtained, later discovery of previously unknown problems or
failure to comply with the applicable regulatory requirements may result in
restrictions on marketing a product or withdrawal of the product from the
market, as well as possible criminal or civil sanctions. All manufacturing
operations also are subject to the FDA's current Good Manufacturing Practice
("cGMP") requirements on an ongoing basis. There can be no assurance that the
Company will be able to attain or maintain compliance with cGMP requirements.
See "Business -- Governmental Regulation."
 
     Dependence on Corporate Collaborators. The Company will depend to a
significant extent on collaborative partners, licensees or other entities for
development, manufacturing and commercialization of its potential products.
Although the Company believes that such collaborative partners would have an
economic motivation to commercialize products that result from the Company's
research and development efforts, the amount and timing of resources devoted to
these activities would be controlled by such partners. Furthermore, there can be
no assurance that present or future collaborators will not pursue existing or
alternative technologies in preference to potential products being developed in
collaboration with the Company.
 
     Competition. The Company is experiencing intense competition from companies
developing gene and cell therapy technologies as well as those using more
traditional approaches to treating human diseases. Many of these 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 distribution than the
Company. Consequently, the Company's competitors may succeed in commercializing
products more rapidly than the Company. The Company's competitors may also
manufacture and market competitive products more successfully than the Company's
potential products. Such developments could render the Company's potential
products less competitive or obsolete. See "Business -- Competition."
 
     Rapid Technological Change. 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 could result in actual and
proposed technologies, products or processes of the Company becoming obsolete
prior to successful commercialization.
 
     Dependence on Key Personnel and Scientific Collaborators. The Company's
success will depend in large part on its ability to attract and retain key
employees and scientific collaborators. There can be no assurance that the
Company will be successful in retaining its existing personnel or in attracting
additional qualified employees. The Company also depends on the continued
availability of outside scientific collaborators who perform research in certain
areas relevant to the Company's research. There can be no assurance that the
Company will be successful in maintaining its relationships with scientific
collaborators, or that inventions or processes developed by the Company's
collaborators will become the property of the Company.
 
     No Commercial Manufacturing or Marketing Capability. The Company's current
facilities and staff will need to be expanded, or supplemented through the use
of contract providers, for large-scale clinical or commercial production of its
potential products. In addition, the Company has no experience in sales and
marketing. To market any products that may result from its development programs,
Targeted Genetics will have to develop marketing and sales capabilities, either
on its own or in conjunction with others. There can be no assurance that the
Company will be successful in obtaining the necessary manufacturing or marketing
capabilities. Furthermore, the Company's dependence upon third parties for the
manufacture, marketing and sale of its potential products may materially
adversely affect the Company's ability to develop and deliver products on a
timely and competitive basis.
 
     Hazardous Materials; Environmental Matters. The Company's research and
development activities involve the controlled use of hazardous materials,
chemicals, biological materials and radioactive compounds. Although the Company
believes that its safety procedures for handling and disposing of such materials
comply with the standards prescribed by applicable laws and regulations, the
risk of accidental contamination or injury from these materials cannot be
completely eliminated. In the event of such an accident, the Company could be
held liable for any resulting damages, and any such liability could exceed the
Company's resources.
 
                                       17
<PAGE>   18
 
     Product Liability. The testing, manufacture, marketing and sale of human
healthcare products entail the inherent risk of liability claims or product
recalls and associated adverse publicity. The Company currently has a limited
amount of product liability insurance. Such insurance is expensive and there can
be no assurance that it will continue to be available in sufficient amounts and
on acceptable terms, if at all. A product liability claim or product recall
could have a material adverse effect on the Company's business, financial
condition and results of operations.
 
ITEM 2. PROPERTIES
 
     Targeted Genetics currently occupies approximately 33,000 square feet of
laboratory and office space in a single facility in Seattle, Washington. The
lease expires on April 1, 1999 and includes options to extend the lease term for
three consecutive five-year periods. The average annual rent payment during the
initial term of the lease is approximately $408,000. In 1996, the Company
entered into a lease for approximately 4,700 square feet of office space in an
office complex adjoining its primary facility. The lease expires on March 31,
2004 and includes options to extend the lease term for two consecutive five-year
periods. The average annual rent payment during the initial term of the lease is
approximately $95,000. The Company believes its current facilities, together
with approximately 2,000 square feet of expansion space remaining in its primary
facility and additional expansion space available in the adjoining office
complex, will be adequate to meet its projected needs for the next several
years. Within that time frame, the Company may be required to locate alternative
facilities, depending on the Company's growth and development.

ITEM 7. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF OPERATIONS
 
OVERVIEW
 
     Targeted Genetics Corporation, a development stage company, was
incorporated in March 1989 as a wholly owned subsidiary of Immunex Corporation.
The Company's activities were carried out as a project within Immunex through
December 31, 1991. In 1992, the Company began to operate independently from
Immunex and raised $16.6 million, net of expenses, in a private placement of
preferred stock. Through public offerings, the Company has raised an additional
$38.4 million. In June 1996, the Company completed a merger with RGene
Therapeutics, Inc. ("RGene"), a privately-held biotechnology company. Currently,
the Company's only significant revenue sources are a research and development
collaborative agreement and interest income earned on investments. The Company
has generated an accumulated deficit of $53.6 million through December 31, 1996.
 
     It is not anticipated that the Company will have any product-related
revenues for a number of years. Accordingly, the Company expects to generate
substantial additional losses in the future attributable to the continuation of
preclinical and clinical research programs, development of manufacturing
capabilities and the preparation for commercialization of its products under
development. The Company's ability to achieve profitability depends in part on
its ability alone and/or with others to complete the development of product
candidates, obtain regulatory approvals, comply with applicable regulatory
requirements and manufacture and market such products, of which there can be no
assurance.
 
RISKS AND UNCERTAINTIES
 
     This discussion contains forward-looking statements that are subject to
certain risks and uncertainties that could cause actual results to differ
materially from those projected. The Company's future cash requirements and
expense levels will depend on many factors, including continued scientific
progress in its research and development programs; the results of research and
development, preclinical studies and clinical
 
                                       19
<PAGE>   20
 
trials; acquisition of products or technology, if any; relationships with
corporate collaborators; competing technological and market developments; the
time and costs involved in filing, prosecuting and enforcing patent claims; the
time and costs of manufacturing scale-up and commercialization activities; and
other factors. Readers are cautioned not to place undue reliance on these
forward-looking statements, which speak only as of the date of this report. The
Company undertakes no obligation to publicly release the results of any
revisions to these forward-looking statements that may be made to reflect events
or circumstances after the date of this report or to reflect the occurrence of
unanticipated events.
 
RESULTS OF OPERATIONS
 
     For the year ended December 31, 1996, revenue under collaborative
agreements increased to $1.2 million from $75,000 for the year ended December
31, 1995. The increase primarily resulted from receipt of milestone payments
totaling $1.5 million net of $375,000 of royalty and other such payments due as
a result of receiving such milestone payments under the Company's collaborative
agreement with Laboratoires Fournier S.C.A. The milestones were earned through
the enrollment of patients in a U.S. clinical trial for the treatment of breast
and ovarian cancer and through completion of certain related regulatory
activities. This agreement provides for additional milestone-based payments in
the future; however, there can be no assurance that such milestones will be
achieved.
 
     Investment income increased each year over the three-year period ended
December 31, 1996. The increases in both 1996 and 1995 were attributable to a
higher average investment balance during the year and higher rates of return on
those balances.
 
     Research and development expenses have steadily increased over the three
years ended December 31, 1996. Contributing to the $3.3 million increase in 1996
expense was approximately $1.6 million related to the RGene merger and
continuation of the acquired research, development and clinical programs. Of
this amount, approximately $1.3 million represented recurring, routine charges
related to the RGene technology, and approximately $300,000 represented
non-recurring employee termination payments. Also contributing to the increase
in expenses in both 1996 and 1995 were a moderate increase in the level of
expenses supporting the advancement of clinical, manufacturing process
development and regulatory programs, as well as additional employees and related
expenses in preclinical immunology. Research and development expenses are
expected to increase in the future, primarily resulting from increased clinical
trial activity. Continued growth, however, is dependent on the availability of
capital.
 
     A one-time expense resulting from the acquisition of RGene was charged
against income in 1996. Of the total RGene purchase price, $13.5 million was
written-off in the second quarter to in-process research and development
expense.
 
     General and administrative expenses increased to $2.9 million for the year
ended December 31, 1996, compared with $2.3 million and $1.9 million for the
years 1995 and 1994, respectively. The increase in 1996 general and
administrative expenses included $338,000 incurred as a result of the RGene
acquisition. These expenses were non-recurring in nature, with no expected
impact on future periods. Other factors contributing to the increases in 1996
and 1995 expenses were increases in business development and investor relations
activities and, to a lesser extent, modest growth in administrative staff.
 
     Interest expense increased to $397,000 for the year ended December 31,
1996, compared to $302,000 and $193,000 for the years 1995 and 1994,
respectively. This expense item relates to equipment financing transactions. The
increase each year is due to an increase in the amount of equipment purchases
financed. The Company expects that it will continue to finance equipment
purchases, if favorable terms are available.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     At December 31, 1996, the Company had cash, cash equivalents and securities
available for sale totaling $19.1 million, compared to $14.4 million at December
31, 1995. The increase was primarily attributable to the completion of a public
stock offering and the cash held by RGene at the time of its acquisition in June
1996. The stock offering resulted in net proceeds of $14.6 million and the
acquisition resulted in net cash received of
 
                                       20
<PAGE>   21
 
$1.6 million. The Company also completed equipment financing transactions
totaling $1.1 million during 1996. Offsetting these increases, the Company used
$10.4 million to fund its operations, $1.7 million for purchases of equipment,
facility expansion and acquisition of technology and $1.0 million for payments
under equipment leases and notes.
 
     The Company expects that its cash needs will continue to increase in future
periods due to expansion of research and development programs, including those
programs acquired as a result of the RGene merger, increased clinical trial
activity, growth of administrative staff and expansion of its facilities to
accommodate increased numbers of employees. Accordingly, the Company will need
to raise substantial additional funds to continue development and
commercialization of its products. The Company's future cash requirements will
be affected by a number of factors, as described above in the section entitled
"Risks and Uncertainties".
 
     The Company estimates that at its current rate of spending, its existing
cash, cash equivalents and securities available for sale will be sufficient to
meet capital requirements at least through the end of 1997. The Company intends
to strengthen its cash position by entering into agreements with corporate
partners that would provide license fees, research and development funding and,
potentially, equity investment. There can be no assurance that the Company will
be successful in establishing any such collaborative arrangements or that any
such future partner would be successful in commercializing products. Also, up to
approximately $3.6 million of additional capital would be provided if warrant
holders were to exercise approximately 770,000 outstanding warrants expiring in
July 1997 and having an exercise price of $4.68. Depending on market conditions,
the Company may also seek additional sources of public or private equity
capital. Any additional funding received by the Company from any of these
potential sources would be expected to extend the period over which the
Company's cash resources would fund its capital requirements. There can be no
assurance, however, that the warrants will be exercised or that adequate funds
will be available when needed or will be available on terms favorable to the
Company.

                         (A DEVELOPMENT STAGE COMPANY)
 
                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
 1. ORGANIZATION
 
     Targeted Genetics Corporation (the "Company") is developing gene therapy
products for the treatment of certain acquired and inherited diseases. As a
development stage company, the Company has devoted substantially all its efforts
to date to conducting research and development activities, recruiting personnel
and raising capital.
 
     The Company was incorporated in the state of Washington in March 1989 as a
wholly owned subsidiary of Immunex Corporation ("Immunex"). In February 1992,
the Company issued 1,920,000 shares of Series A convertible preferred stock to
Immunex in exchange for the grant of a license to certain technology, settlement
of advances from Immunex and cancellation of 40,000 shares of common stock
issued by the Company to Immunex on March 28, 1989. At December 31, 1996,
Immunex held 13% of the outstanding stock of the Company.
 
     The Company estimates that, at its current rate of expenditures, its
existing cash, cash equivalents and securities available for sale will be
sufficient to meet operating requirements at least through the end of 1997.
Accordingly, the Company is pursuing collaborative arrangements with corporate
partners, with the intent of generating both research and development funding
and equity capital. The Company may also elect to seek additional equity capital
via the public or private markets, depending on market conditions.
 
 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The consolidated financial statements include the accounts of the Company
and its wholly owned subsidiary. All intercompany transactions and balances have
been eliminated in consolidation.
 
  Cash Equivalents
 
     The Company considers all short-term investments with a purchased maturity
of three months or less to be cash equivalents. Cash equivalents, valued at cost
which approximates market, consist principally of money market accounts and
short-term government obligations.
 
  Securities Available for Sale
 
     Securities available for sale consist primarily of corporate debt
securities and U.S. Government notes, all of which mature within two years.
Management currently classifies the Company's entire investment portfolio, other
than cash equivalents, 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.
 
  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, ranging 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.

                         (A DEVELOPMENT STAGE COMPANY)
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
  Stock Compensation
 
     In adopting the provisions of Statement of Financial Accounting Standards
(SFAS) No. 123 "Accounting for Stock-Based Compensation," the Company has
elected to apply the disclosure-only provisions and related interpretations for
accounting 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.
 
  Revenue Under Collaborative Agreements
 
     Revenue under collaborative agreements is recognized as defined under the
terms of the respective collaborative agreements. Revenue related to milestones
is recognized upon the achievement of the related milestone and when collection
is probable. Royalty payments and other similar payments due as a direct result
of such revenues being earned and received are offset against and recognized in
the same period as such revenue.
 
  Net Loss Per Share
 
     Net loss per share is computed based upon the weighted average number of
common shares outstanding during the period. Common equivalent shares are not
included in the computation because the effect of their inclusion would be
antidilutive, except that, in accordance with Securities and Exchange Commission
requirements, common equivalent shares issued during the twelve months prior to
the Company's initial public offering have been included in the calculation as
if they were outstanding through March 31, 1994.
 
  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.
 
  Reclassification
 
     Certain reclassifications have been made to prior year financial statements
to conform to the current year presentation.

 6. SHAREHOLDERS' EQUITY
 
  Warrants
 
     In July 1995, the Company issued warrants to purchase 830,598 shares in
conjunction with an offering of its common stock. At December 31, 1996, 769,598
of such warrants were outstanding and exercisable at a price of $4.68 per share,
expiring July 1997. The Company has issued a total of 62,016 warrants related to
equipment financing agreements. These warrants have a weighted average price of
$6.00 per share and expire from May 1999 to December 2003. At December 31, 1996,
831,614 shares of common stock were reserved for all such warrants.
 
  Shareholder Rights Plan
 
     In October 1996, the Company adopted a Shareholder Rights Plan under which
it distributed a dividend of one right for each outstanding share of common
stock. The issuance of these rights had no dilutive effect, did not impact
reported earnings per share and is not taxable to the Company or the Company's
shareholders. These rights could cause substantial dilution to certain persons
or groups that attempt to acquire the Company on terms not approved by the Board
of Directors.
 
  Stock Options
 
     The Company has two stock option plans under which 2,120,000 shares of
common stock were reserved for issuance. Generally, options vest in annual
increments over a three- or five-year period. All options expire ten years from
date of grant. Options have been granted at market value or, prior to the
Company's initial public offering, at the estimated fair value at the date of
grant as established by the Company's Board of Directors. As of December 31,
1996, options on 782,666 shares were available for future grant.

contributions to the plan made by the Company in 1995 or 1994.
 
10. INCOME TAXES
 
     At December 31, 1996, the Company had net operating loss carryforwards of
$39,270,000 and research and experimental credit carryforwards of $1,074,000.
The carryforwards are available to offset future federal income taxes and begin
to expire in 2007. At December 31, 1996 and 1995, the Company 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 $5,717,000 and
$3,350,000 during 1996 and 1995, respectively.

     Utilization of federal income tax carry forwards is subject to certain
limitations under Section 382 of the Internal Revenue Code of 1986. The
Company's past sales of common stock have resulted in "ownership changes" as
defined under Section 382, resulting in limitations on the future use of carry
forwards. At December 31, 1996, the Company calculated its annual limitation to
be approximately $3,782,000. However, this annual limitation is not expected to
have a material adverse effect on the Company's utilization of its net operating
loss and research credit carryforwards.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
Targeted Genetics Corporation
 
     We have audited the accompanying consolidated balance sheets of Targeted
Genetics Corporation (a development stage company) as of December 31, 1996 and
1995, and the related consolidated statements of operations, shareholders'
equity, and cash flows for each of the three years in the period ended December
31, 1996 and the period from March 9, 1989 (date of inception) through December
31, 1996. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as 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 consolidated financial position of Targeted
Genetics Corporation (a development stage company) at December 31, 1996 and
1995, and the consolidated results of its operations and its cash flows for each
of the three years in the period ended December 31, 1996 and the period from
March 9, 1989 (date of inception) through December 31, 1996 in conformity with
generally accepted accounting principles.

          4.2.2  DIVIDENDS

     Subject to any preferential rights granted for any series of Preferred

          4.2.3  VOTING

     This corporation may from time to time issue and dispose of any of the
authorized and unissued shares of the Common Stock or the Preferred Stock for
such consideration as may be fixed from time to time by the Board of Directors,
without action by the shareholders. The Board of Directors may provide for
payment therefor to be received by this corporation in cash, property, services
or such other consideration as is approved by the Board of Directors. Any and
all such shares of the Common Stock or the Preferred Stock of this corporation,
the issuance of which has been so authorized, and for which consideration so
fixed by the Board of Directors has been paid or delivered, shall be deemed
fully paid stock and shall not be liable to any further call or assessment
thereon.

        4.3    DESIGNATION OF RIGHTS AND PREFERENCES OF SERIES A PARTICIPATING
        CUMULATIVE PREFERRED STOCK

        The following series of Preferred Stock is hereby designated, which
series shall have the rights, preferences and privileges and limitations set
forth below:

               4.3.1      DESIGNATION OF SERIES A PARTICIPATING CUMULATIVE
                          PREFERRED STOCK

        The shares of such series shall be designated the "Series A
Participating Cumulative Preferred Stock" (the "Series A Preferred Stock"), par
value $.01 per share. The number of


                                       46
<PAGE>   4

shares initially constituting the Series A Preferred Stock shall be 400,000;
provided, however, if more than a total of 400,000 shares of Series A Preferred
Stock shall be issuable upon the exercise of Rights (the "Rights") issued
pursuant to the Rights Agreement dated as of October 17, 1996 between the
corporation and ChaseMellon Shareholder Services, as Rights Agent (the "Rights
Agreement"), the corporation's Board of Directors, pursuant to Section
23B.06.020 of the Revised Code of Washington, shall direct by resolution or
resolutions that Articles of Amendment be properly executed and filed with the
Washington Secretary of State providing for the total number of shares of Series
A Preferred Stock authorized for issuance to be increased (to the extent that
the Restated Articles of Incorporation then permits) to the largest number of
whole shares (rounded up to the nearest whole number) issuable upon exercise of
such Rights. In addition, such number of shares may be decreased by resolution
of the Board of Directors; provided, however, that no decrease shall reduce the
number of shares of Series A Preferred Stock to a number less than the number of
shares then outstanding plus the number of shares reserved for issuance upon the
exercise of outstanding options, rights or warrants or upon the conversion of
any outstanding securities issued by the corporation convertible into Series A
Preferred Stock.

               4.3.2 DIVIDENDS AND DISTRIBUTIONS

(a)  Subject to the prior and superior rights of the holders of shares of any
other series of Preferred Stock or other class of capital stock of the
corporation ranking prior and superior to the shares of Series A Preferred Stock
with respect to dividends, the holders of shares of Series A Preferred Stock
shall be entitled to receive, when, as, and if declared by the Board of
Directors, out of the assets of the corporation legally available therefor,
quarterly dividends payable in cash on the last day of each fiscal quarter in
each year, or such other dates as the corporation's Board of Directors shall
approve (each such date being referred to in this Designation as a "Quarterly
Dividend Payment Date"), commencing on the first Quarterly Dividend Payment Date
after the first issuance of a share or a fraction of a share of Series A
Preferred Stock, in an amount per share (rounded to the nearest cent) equal to
the greater of (i) $.01 and (ii) the Formula Number (as hereinafter defined)
then in effect times the cash dividends then to be paid on each share of Common
Stock. In addition, if the corporation shall pay any dividend or make any
distribution on the Common Stock payable in assets, securities or other forms of
noncash consideration (other than dividends or distributions solely in shares of
Common Stock), then, in each such case, the corporation shall simultaneously pay
or make on each outstanding whole share of Series A Preferred Stock a dividend
or distribution in like kind equal to the Formula Number then in effect times
such dividend or distribution on each share of Common Stock. As used in this
Designation and in the Rights Agreement, the "Formula Number" shall be 100;
provided, however, that if at any time after October 17, 1996 the corporation
shall (i) declare or pay any dividend on the Common Stock payable in shares of
Common Stock or make any distribution on the Common Stock in shares of Common
Stock, (ii) subdivide (by a stock split or otherwise) the outstanding shares of
Common Stock into a larger number of shares of Common Stock, or (iii) combine
(by a reverse stock split or otherwise) the outstanding shares of Common Stock
into a smaller number of shares of Common Stock, then in each such event the
Formula Number shall be adjusted to a number determined by multiplying the
Formula Number in 


                                       47
<PAGE>   5

effect immediately prior to such event by a fraction, the numerator of which is
the number of shares of Common Stock that are outstanding immediately after such
event and the denominator of which is the number of shares of Common Stock that
are outstanding immediately prior to such event (and rounding the result to the
nearest whole number); and provided further, that if at any time after October
17, 1996 the corporation shall issue any shares of its capital stock in a
merger, reclassification or change of the outstanding shares of Common Stock,
then in each such event the Formula Number shall be appropriately adjusted to
reflect such merger, reclassification or change so that each share of Preferred
Stock continues to be the economic equivalent of a Formula Number of shares of
Common Stock prior to such merger, reclassification or change.

               (b) The Corporation shall declare a dividend or distribution on
the Series A Preferred Stock as provided in Section 4.3.2(a) immediately prior
to or at the same time it declares a dividend or distribution on the Common
Stock (other than a dividend or distribution solely in shares of Common Stock);
provided, however, that in the event no dividend or distribution (other than a
dividend or distribution in shares of Common Stock) shall have been declared on
the Common Stock during the period between any Quarterly Dividend Payment Date
and the next subsequent Quarterly Dividend Payment Date, a dividend of $.01 per
share on the Series A Preferred Stock shall nevertheless be payable on such
subsequent Quarterly Dividend Payment Date. The Corporation's Board of Directors
may fix a record date for the determination of holders of shares of Series A
Preferred Stock entitled to receive a dividend or distribution declared thereon,
which record date shall be the same as the record date for any corresponding
dividend or distribution on the Common Stock and which shall not be more than 60
days prior to the date fixed for payment thereof.

(c)  Dividends shall begin to accrue and be cumulative on outstanding shares of
Series A Preferred Stock from and after the Quarterly Dividend Payment Date next
preceding the date of original issue of such shares of Series A Preferred Stock;
provided, however, that dividends on such shares that are originally issued
after the record date for the determination of holders of shares of Series A
Preferred Stock entitled to receive a quarterly dividend on or prior to the next
succeeding Quarterly Dividend Payment Date shall begin to accrue and be
cumulative from and after such Quarterly Dividend Payment Date. Notwithstanding
the foregoing, dividends on shares of Series A Preferred Stock that are
originally issued prior to the record date for the determination of holders of
shares of Series A Preferred Stock entitled to receive a quarterly dividend on
or prior to the first Quarterly Dividend Payment Date shall be calculated as if
cumulative from and after the last day of the fiscal quarter (or such other
Quarterly Dividend Payment Date as the corporation's Board of Directors shall
approve) next preceding the date of original issuance of such shares. Accrued
but unpaid dividends shall not bear interest. Dividends paid on the shares of
Series A Preferred Stock in an amount less than the total amount of such
dividends at the time accrued and payable on such shares shall be allocated pro
rata on a share-by-share basis among all such shares at the time outstanding.

               (d) So long as any shares of Series A Preferred Stock are
outstanding, no dividends or other distributions shall be declared, paid or
distributed, or set aside for payment 

                                       48
<PAGE>   6

or distribution, on the Common Stock unless, in each case, the dividend required
by this Section 4.3.2 to be declared on the Series A Preferred Stock shall have
been declared.

               (e) The holders of shares of Series A Preferred Stock shall not
be entitled to receive any dividends or other distributions except as provided
in this Designation.

               4.3.3      VOTING RIGHTS

The holders of shares of Series A Preferred Stock shall have the following
voting rights:

               (a) Each holder of Series A Preferred Stock shall be entitled to
a number of votes equal to the Formula Number then in effect for each share of
Series A Preferred Stock held of record on each matter on which holders of the
Common Stock or shareholders generally are entitled to vote, multiplied by the
maximum number of votes per share that any holders of the Common Stock or
shareholders generally then have with respect to such matter (assuming any
holding period or other requirement to vote a greater number of shares is
satisfied).

               (b) Except as otherwise provided in this Designation or by
applicable law, the holders of shares of Series A Preferred Stock and the
holders of shares of Common Stock and any other capital stock of the corporation
having general voting rights shall vote together as one class for the election
of directors of the corporation and on all other matters submitted to a vote of
shareholders of the corporation.

               (c) Except as provided in this Designation or by applicable law,
holders of Series A Preferred Stock shall have no special voting rights and
their consent shall not be required (except to the extent they are entitled to
vote with holders of Common Stock as set forth in this Designation) for
authorizing or taking any corporate action.

               4.3.4      CERTAIN RESTRICTIONS

               (a) Whenever quarterly dividends or other dividends or
distributions payable on the Series A Preferred Stock as provided in Section
4.3.2 are in arrears, thereafter and until all accrued and unpaid dividends and
distributions, whether or not declared, on shares of Series A Preferred Stock
outstanding shall have been paid in full, the corporation shall not:

                       (i) declare or pay dividends on, make any other
        distributions on, or redeem or purchase or otherwise acquire for
        consideration any shares of stock ranking junior (either as to dividends
        or upon liquidation, dissolution or winding up) to the Series A
        Preferred Stock;

                       (ii) declare or pay dividends on or make any other
        distributions on any shares of stock ranking on a parity (either as to
        dividends or upon liquidation, dissolution or winding up) with the
        Series A Preferred Stock, except dividends paid ratably on the Series A
        Preferred Stock and all such parity stock on which dividends

                                       49
<PAGE>   7

        are payable or in arrears in proportion to the total amounts to which
        the holders of all such shares are then entitled;

                       (iii) redeem or purchase or otherwise acquire for
        consideration shares of any stock ranking junior (either as to dividends
        or upon liquidation, dissolution or winding up) with the Series A
        Preferred Stock; provided, however, that the corporation may at any time
        redeem, purchase or otherwise acquire shares of any such junior stock in
        exchange for shares of any stock of the corporation ranking junior
        (either as to dividends or upon dissolution, liquidation or winding up)
        to the Series A Preferred Stock; or

                       (iv) redeem or purchase or otherwise acquire for
        consideration any shares of Series A Preferred Stock, or any shares of
        stock ranking on a parity with the Series A Preferred Stock, except in
        accordance with a purchase offer made in writing or by publication (as
        determined by the corporation's Board of Directors) to all holders of
        such shares upon such terms as the corporation's Board of Directors,
        after consideration of the respective annual dividend rates and other
        relative rights and preferences of the respective series and classes,
        shall determine in good faith will result in fair and equitable
        treatment among the respective series or classes.

               (b) The corporation shall not permit any subsidiary of the
corporation to purchase or otherwise acquire for consideration any shares of
stock of the corporation unless the corporation could, under paragraph (a) of
this Section 4.3.4, purchase or otherwise acquire such shares at such time and
in such manner.

               4.3.5      LIQUIDATION RIGHTS

        Upon the liquidation, dissolution or winding up of the corporation,
whether voluntary or involuntary, no distribution shall be made to (a) the
holders of shares of stock ranking junior (either as to dividends or upon
liquidation, dissolution or winding up) to the Series A Preferred Stock unless,
prior thereto, the holders of shares of Series A Preferred Stock shall have
received an amount equal to the greater of (i) $.01 per share and (ii) the
accrued and unpaid dividends and distributions thereon, whether or not declared,
to the date of such payment, plus an aggregate amount per share equal to the
Formula Number then in effect times the aggregate amount to be distributed per
share to holders of Common Stock or (b) the holders of shares of stock ranking
on a parity (either as to dividends or upon liquidation, dissolution or winding
up) with the Series A Preferred Stock, except distributions made ratably on the
Series A Preferred Stock and all other such parity stock in proportion to the
total amounts to which the holders of all such shares are entitled upon such
liquidation, dissolution or winding up.

               4.3.6      CONSOLIDATION, MERGER, ETC.


        In case the corporation shall enter into any consolidation, merger,
combination or other transaction in which the shares of Common Stock are
exchanged for or changed into


                                       50
<PAGE>   8

other stock or securities, cash and/or any other property, then in any such case
the then outstanding shares of Series A Preferred Stock shall at the same time
be similarly exchanged or changed into an amount per share equal to the Formula
Number then in effect times the aggregate amount of stock, securities, cash
and/or any other property (payable in kind), as the case may be, into which or
for which each share of Common Stock is exchanged or changed. In the event both
this Section 4.3.6 and Section 4.3.2 appear to apply to a transaction, this
Section 4.3.6 will control.

               4.3.7      NO REDEMPTION; NO SINKING FUND

               (a) The shares of Series A Preferred Stock shall not be subject
to redemption by the corporation or at the option of any holder of Series A
Preferred Stock; provided, however, that the corporation may purchase or
otherwise acquire outstanding shares of Series A Preferred Stock in the open
market or by offer to any holder or holders of shares of Series A Preferred
Stock.

               (b) The shares of Series A Preferred Stock shall not be subject
to or entitled to the operation of a retirement or sinking fund.

               4.3.8      RANKING

        The Series A Preferred Stock shall rank junior to all other series of
Preferred Stock of the corporation, unless the corporation's Board of Directors
shall specifically determine otherwise in fixing the powers, preferences and
relative, participating, optional and other special rights of the shares of such
series and the qualifications, limitations and restrictions thereof.

               4.3.9      FRACTIONAL SHARES



        The Series A Preferred Stock shall be issuable upon exercise of the
Rights issued pursuant to the Rights Agreement in whole shares or in any
fractional share that is one one-hundredth (1/100th) of a share or any integral
multiple of such fraction, and shall entitle the holder, in proportion to such
holder's fractional shares, to receive dividends, exercise voting rights,
participate in distributions and have the benefit of all other rights of holders
of Series A Preferred Stock. In lieu of fractional shares, the corporation,
prior to the first issuance of a share or a fractional share of Series A
Preferred Stock, may elect to (a) make a cash payment as provided in the Rights
Agreement for a fractional share other than one one-hundredth (1/100th) of a
share or any integral multiple thereof or (b) issue depository receipts
evidencing such authorized fractional share of Series A Preferred Stock pursuant
to an appropriate agreement between the corporation and a depository selected by
the corporation; provided, however, that such agreement shall provide that the
holders of such depository


                                       51
<PAGE>   9

receipts shall have all the rights, privileges and preferences to which they are
entitled as holders of the Series A Preferred Stock.

               4.3.10     REACQUIRED SHARES

        Any shares of Series A Preferred Stock purchased or otherwise acquired
by the corporation in any manner whatsoever shall be retired and canceled
promptly after the acquisition thereof. All such shares shall upon their
cancellation become authorized but unissued shares of Preferred Stock, without
designation as to series until such shares are once more designated as part of a
particular series by the corporation's Board of Directors pursuant to the
provisions of Article 4 of the Restated Articles of Incorporation.

               4.3.11     AMENDMENT

        None of the powers, preferences and relative, participating, optional
and other special rights of the Series A Preferred Stock as provided in this
Designation or in the Restated Articles of Incorporation shall be amended in any
manner that would alter or change the powers, preferences, rights or privileges
of the holders of Series A Preferred Stock so as to affect them adversely
without the affirmative vote of the holders of at least 66-2/3% of the
outstanding shares of Series A Preferred Stock, voting as a separate class.

                          ARTICLE 5. PREEMPTIVE RIGHTS

     No preemptive rights shall exist with respect to shares of stock or
securities convertible into shares of stock of this corporation.

                          ARTICLE 6. CUMULATIVE VOTING

     The right to cumulate votes in the election of Directors shall not exist
with respect to shares of stock of this corporation.

                    ARTICLE 7. BYLAWS

     The Board of Directors shall have the power to adopt, amend or repeal the
Bylaws of this corporation subject to approval by a majority of the Continuing
Directors (as defined in Article 13); provided, however, the Board of Directors
may not repeal or amend any bylaw that the shareholders have expressly provided
may not be amended or repealed by the Board of Directors. The shareholders shall

outstanding shares and, to the extent, if any, provided by resolution or
resolutions of the Board of Directors providing for the issuance of a series of
Common or Preferred Stock, not less than two-thirds of the outstanding shares
entitled to vote thereon, voting as a class.

                     ARTICLE 8. REGISTERED OFFICE AND AGENT

      The name of the registered agent of this corporation and the address of
its current registered office are as follows:

three being assigned to Class 3 and Class 2, as appropriate. At each annual
meeting of shareholders, the number of Directors equal to the number of
Directors in the class whose term expires at the time of such meeting shall be
elected to serve until the third ensuing annual meeting of shareholders.
Notwithstanding any of the foregoing provisions of this Article 9, Directors
shall serve until their successors are elected and qualified or until their
earlier death, resignation or removal from office, or until there is a decrease
in the number of Directors. The Directors of this corporation may be removed
only for cause by the holders of not less than two-thirds of the shares entitled
to elect the Director or Directors whose removal is sought in the manner
provided by the Bylaws.

               ARTICLE 10. AMENDMENTS TO ARTICLES OF INCORPORATION

     This corporation reserves the right to amend or repeal, by the affirmative
vote of the holders of a majority of the outstanding shares and, to the extent,
if any, provided by resolution or resolutions of the Board of Directors
providing for the issuance of a series of Common or Preferred stock, a majority
of the outstanding shares entitled to vote thereon, voting as a class, any of
the provisions contained in these Articles of Incorporation; provided, however,
that amendment or repeal of Article 7, Article 9, Article 10, Article 12 or
Article 13 shall require the affirmative vote of the holders of two-thirds of
the outstanding shares. The rights of the shareholders of this corporation are
granted subject to this reservation; provided, however, that the holders of the
outstanding shares of a class shall be entitled to vote as a class upon a
proposed amendment if the amendment would increase or decrease the aggregate
number of authorized shares of such class, increase or decrease the par value of
the shares of such class, or alter or change the powers, preferences or special
rights of the shares of such class so as to affect them adversely. If any
proposed amendment would alter or change the powers, preferences or special
rights of one or more series of any class so as to affect them adversely, but
shall not affect the entire class, then only the shares of the series so
affected by the amendment shall be considered as a separate class for the
purposes of this Article 10. Notwithstanding the provisions of this Article 10,
the number of authorized shares of any such class or classes of stock may be
increased by the affirmative vote of the holders of a majority of the
outstanding shares entitled to vote thereon or decreased (but not below the
number of shares thereof then outstanding) by the affirmative vote of the
holders of a majority of the outstanding shares entitled to vote thereon, if so
provided in any amendment which created such class or classes of stock or which
was adopted prior to the issuance of any shares of such class or classes of
stock, or in any amendment which was authorized by a resolution or resolutions
adopted by the affirmative vote of the holders of a majority of such class or
classes of stock.



                  ARTICLE 11. LIMITATION OF DIRECTOR LIABILITY

     To the full extent that the Washington Business Corporation Act, as it
exists on the date hereof or may hereafter be amended, permits the limitation or
elimination of the liability of Directors, a Director of this corporation shall
not be liable to this corporation or its shareholders for monetary damages for
conduct as a Director. Any amendments to or repeal of this Article

                                       53
<PAGE>   11

11 shall not adversely affect any right or protection of a Director of this
corporation for or with respect to any acts or omissions of such Director
occurring prior to such amendment or repeal.

                  ARTICLE 12. SPECIAL MEETINGS OF SHAREHOLDERS

     The Chairman of the Board of Directors, the President or the Board of
Directors may call special meetings of the shareholders for any purpose.
Further, a special meeting of the shareholders shall be held if the holders of
not less than thirty percent (30%) of all the votes entitled to be cast on any
issue proposed to be considered at such special meeting have dated, signed and
delivered to the Secretary one or more written demands for such meeting,
describing the purpose or purposes for which it is to be held.

facsimile of the notice to like equipment which receives and reproduces such
notice. If these forms of written notice are impractical in the view of the
Board, the Chairman of the Board, the President or the Secretary, written notice
may be transmitted by an advertisement in a newspaper of general circulation in
the area of the corporation's principal office. If such notice is mailed, it
shall be deemed effective when deposited in the official government mail,
first-class postage prepaid, properly addressed to the shareholder at such
shareholder's address as it appears in the corporation's current record of
shareholders. Notice given in any other manner shall be deemed effective when
dispatched to the shareholder's address, telephone number or other number

2.6    BUSINESS FOR SHAREHOLDERS' MEETINGS

       2.6.1  BUSINESS AT ANNUAL MEETINGS

       In addition to the election of directors, other proper business may be
transacted at an annual meeting of shareholders, provided that such business is
properly brought before such meeting. To be properly brought before an annual
meeting, business must be (a) brought by or at the direction of the Board or (b)
brought before the meeting by a shareholder pursuant to written notice thereof,
in accordance with subsection 2.6.3 hereof, and received by the Secretary not
fewer than sixty nor more than ninety days prior to the date specified in
subsection 2.1 hereof for such annual meeting (or if less than sixty days'
notice or prior public disclosure of the date of the annual meeting is given or
made to the shareholders, not later than the tenth day following the day on
which the notice of the date of the 

                                       66
<PAGE>   9

annual meeting was mailed or such public disclosure was made). Any such
shareholder notice shall set forth (i) the name and address of the shareholder
proposing such business; (ii) a representation that the shareholder is entitled
to vote at such meeting and a statement of the number of shares of the
corporation which are beneficially owned by the shareholder; (iii) a
representation that the shareholder intends to appear in person or by proxy at
the meeting to propose such business; and (iv) as to each matter the shareholder
proposes to bring before the meeting, a brief description of the business
desired to be brought before the meeting, the reasons for conducting such
business at the meeting, the language of the proposal (if appropriate), and any
material interest of the shareholder in such business. No business shall be
conducted at any annual meeting of shareholders except in accordance with this
subsection 2.6.1. If the facts warrant, the Board, or the chairman of an annual
meeting of shareholders, may determine and declare (x) that a proposal does not
constitute proper business to be transacted at the meeting or (y) that business
was not properly brought before the meeting in accordance with the provisions of
this subsection 2.6.1 and, if, in either case, it is so determined, any such
business shall not be transacted. The procedures set forth in this subsection
2.6.1 for business to be properly brought before an annual meeting by a
shareholder are in addition to, and not in lieu of, the requirements set forth
in Rule 14a-8 under Section 14 of the Securities Exchange Act of 1934, as
amended, or any successor provision.

       2.6.2  BUSINESS AT SPECIAL MEETINGS

       At any special meeting of the shareholders, only such business as is
specified in the notice of such special meeting given by or at the direction of
the person or persons calling such meeting, in accordance with subsection 2.5
hereof, shall come before such meeting.

       2.6.3  NOTICE TO CORPORATION

       Any written notice required to be delivered by a shareholder to the
corporation pursuant to subsection 2.5, subsection 2.6.1 or subsection 2.6.2
hereof must be given, either by personal delivery or by registered or certified
mail, postage prepaid, to the Secretary at the corporation's executive offices
in the city of Seattle, state of Washington.

2.7    WAIVER OF NOTICE

       Whenever any notice is required to be given to any shareholder under the
provisions of these Bylaws, the Articles of Incorporation or the Washington
Business Corporation Act, a waiver thereof in writing, signed by the person or

                                       67
<PAGE>   10

persons entitled to such notice and delivered to the corporation, whether before
or after the date and time of the meeting, shall be deemed equivalent to the
giving of such notice. Further, notice of the time, place and purpose of any
meeting will be deemed to be waived by any shareholder by attendance at such
meeting in person or by proxy, unless such shareholder at the beginning of the
meeting objects to holding the meeting or transacting business at the meeting.

2.8    FIXING OF RECORD DATE FOR DETERMINING SHAREHOLDERS


       For the purpose of determining shareholders entitled (a) to notice of or
to vote at any meeting of shareholders or any adjournment thereof, (b) to demand
a special meeting, or (c) to receive payment of any dividend, or in order to
make a determination of shareholders for any other purpose, the Board may fix a
future date as the record date for any such determination. Such record date
shall be not more than seventy days, and in case of a meeting of shareholders
not less than thirty days prior to the date on which the particular action
requiring such determination is to be taken. If no record date is fixed for the
determination of shareholders entitled to notice of or to vote at a meeting, the
record date shall be the day immediately preceding the date on which notice of
the meeting is first given to shareholders. Such a determination shall apply to
any adjournment of the meeting unless the Board fixes a new record date, which
it shall do if the meeting is adjourned to a date more than one hundred twenty
days after the date fixed for the original meeting. If no record date is set for
the determination of shareholders entitled to receive payment of any stock
dividend or distribution (other than one involving a purchase, redemption or
other acquisition of the corporation's shares) the record date shall be the date
the Board authorizes the stock dividend or distribution.

2.9    VOTING RECORD

       At least ten days before each meeting of shareholders, an alphabetical
list of the shareholders entitled to notice of such meeting shall be made,
arranged by voting group and by each class or series of shares therein, with the
address of and number of shares held by each shareholder. This record shall be
kept at the principal office of the corporation for ten days prior to such
meeting, and shall be kept open at such meeting, for the inspection of any
shareholder or any shareholder's agent.

2.10   QUORUM

       A majority of the votes entitled to be cast on a matter by the holders of
shares that, pursuant to the Articles of Incorporation or the Washington
Business Corporation Act, are entitled to vote and be counted collectively upon
such matter,


                                       68
<PAGE>   11

represented in person or by proxy, shall constitute a quorum of such shares at a
meeting of shareholders. If less than a majority of such votes are represented
at a meeting, a majority of the votes so represented may adjourn the meeting
from time to time without further notice if the new date, time or place is
announced at the meeting before adjournment. Any business may be transacted at a
reconvened meeting that might have been transacted at the meeting as originally
called, provided a quorum is present or represented at such meeting. Once a
share is represented for any purpose at a meeting other than solely to object to
holding the meeting or transacting business at such meeting, it is deemed
present for quorum purposes for the remainder of the meeting and any adjournment
thereof (unless a new record date is or must be set for the adjourned meeting)
notwithstanding the withdrawal of enough shareholders to leave less than a
quorum.

2.11   MANNER OF ACTING

       If a quorum is present, action on a matter other than the election of
Directors shall be approved if the votes cast in favor of the action by the
shares entitled to vote and be counted collectively upon such matter exceed the
votes cast against such action by the shares entitled to vote and be counted
collectively thereon, unless the Articles of Incorporation or the Washington
Business Corporation Act requires a greater number of affirmative votes.

2.12   PROXIES

       A shareholder may vote by proxy executed in writing by the shareholder or
by his or her attorney-in-fact or agent. Such proxy shall be effective when
received by the Secretary or other officer or agent authorized to tabulate
votes. A proxy shall become invalid eleven months after the date of its
execution, unless otherwise provided in the proxy. A proxy with respect to a
specified meeting shall entitle the holder thereof to vote at any reconvened
meeting following adjournment of such meeting but shall not be valid after the
final adjournment thereof.

2.13   VOTING OF SHARES

       Except as provided in the Articles of Incorporation or in Section 2.14
hereof, each outstanding share entitled to vote with respect to a matter
submitted to a meeting of shareholders shall be entitled to one vote upon such
matter.

2.14   VOTING FOR DIRECTORS

       Each shareholder entitled to vote at an election of Directors may vote,
in person or by proxy, the number of shares owned by such shareholder for as
many persons as there are Directors to be elected and for whose election such
shareholder 

                                       69
<PAGE>   12

has a right to vote. Unless otherwise provided in the Articles of Incorporation
or in Section 3.14 hereof, the candidates elected shall be those receiving the
largest number of votes cast, up to the number of Directors to be elected.

2.15   ACTION BY SHAREHOLDERS WITHOUT A MEETING

       Any action which could be taken at a meeting of the shareholders may be
taken without a meeting if one or more written consents setting forth the action
so taken are signed by all shareholders entitled to vote on the action and are
delivered to the corporation. If not otherwise fixed by the Board, the record
date for determining shareholders entitled to take action without a meeting is
the date the first shareholder signs the consent. A shareholder may withdraw a
consent only by delivering a written notice of withdrawal to the corporation
prior to the time that all consents are in the possession of the corporation.
Action taken by written consent of shareholders without a meeting is effective
when all consents are in the possession of the corporation, unless the consent
specifies a later effective date. Any such consent shall be inserted in the
minute book as if it were the minutes of a meeting of the shareholders.

                         SECTION 3. BOARD OF DIRECTORS

3.1    GENERAL POWERS

       All corporate powers shall be exercised by or under the authority of, and
the business and affairs of the corporation shall be managed under the direction
of, the Board, except as may be otherwise provided in these Bylaws, the Articles
of Incorporation or the Washington Business Corporation Act.

3.2    NUMBER AND TENURE

       The Board shall be composed of not less than one nor more than nine
Directors, the specific number to be set by resolution of the Board or the
shareholders. The number of Directors may be changed from time to time by
amendment to these Bylaws, but no decrease in the number of Directors shall have
the effect of shortening the term of any incumbent Director. Directors need not
be shareholders of the corporation or residents of the state of Washington and
need not meet any other qualifications.


       The Board shall be divided into three classes, with such classes to be as
equal in number as may be possible, with any Director or Directors in excess of
the number divisible by three being assigned to Class 3 and Class 2, as
appropriate. At each annual meeting of shareholders the number of Directors
equal to the number of Directors in the class whose term expires at the time of
such meeting shall be elected 



                                       70
<PAGE>   13

to serve until the third ensuing annual meeting of shareholders. Notwithstanding
any of the foregoing provisions of this Section 3.2, Directors shall serve until
their successors are elected and qualified or until their earlier death,
resignation or removal from office or until there is a decrease in the number of
Directors.

3.3    NOMINATION AND ELECTION.

       3.3.1  NOMINATION

       Only persons who are nominated in accordance with the following
procedures shall be eligible for election as Directors. Nominations for the
election of Directors may be made (a) by or at the direction of the Board or (b)
by any shareholder of record entitled to vote for the election of Directors at
such meeting; provided, however, that a shareholder may nominate persons for
election as Directors only if written notice (in accordance with subsection
2.6.3 hereof) of such shareholder's intention to make such nominations is
received by the Secretary not later than (i) with respect to an election to be
held at an annual meeting of the shareholders, not fewer than sixty nor more
than ninety days prior to the date specified in subsection 2.1 hereof for such
annual meeting (or if less than sixty days' notice or prior public disclosure of
the date of the annual meeting is given or made to the shareholders, not later
than the tenth day following the day on which such notice of the date of the
annual meeting was mailed or such public disclosure was made) and (ii) with
respect to an election to be held at a special meeting of the shareholders for
the election of Directors, the close of business on the seventh business day
following the date on which notice of such meeting is first given to
shareholders. Any such shareholder's notice shall set forth (a) the name and
address of the shareholder who intends to make a nomination; (b) a
representation that the shareholder is entitled to vote at such meeting and a
statement of the number of shares of the corporation which are beneficially
owned by the shareholder; (c) a representation that the shareholder intends to
appear in person or by proxy at the meeting to nominate the person or persons
specified in the notice; (d) as to each person the shareholder proposes to
nominate for election or re-election as a Director, the name and address of such
person and such other information regarding such nominee as would be required in
a proxy statement filed pursuant to the proxy rules of the Securities and
Exchange Commission had such nominee been nominated by the Board, and a
description of any arrangements or understandings, between the shareholder and
such nominee and any other persons (including their names), pursuant to which
the nomination is to be made; and (e) the consent of each such nominee to serve
as a Director if elected. If the facts warrant, the Board, or the chairman of a
shareholders' meeting at which Directors are to be elected, shall determine and
declare that a nomination was not made in accordance with the foregoing
procedure and, if it is so determined, the defective nomination 


                                       71
<PAGE>   14

shall be disregarded. The right of shareholders to make nominations pursuant to
the foregoing procedure is subject to the rights of the holders of any class or
series of stock having a preference over the Common Stock as to dividends or
upon liquidation. The procedures set forth in this subsection 3.3 for nomination
for the election of Directors by shareholders are in addition to, and not in
limitation of, any procedures now in effect or hereafter adopted by or at the
direction of the Board or any committee thereof.

       3.3.2  ELECTION

       At each election of Directors, the persons receiving the greatest number
of votes shall be the Directors.

3.4    ANNUAL AND REGULAR MEETINGS

       An annual Board meeting shall be held without notice immediately after
and at the same place as the annual meeting of shareholders. By resolution the
Board, or any committee thereof, may specify the time and place either within or
without the state of Washington for holding regular meetings thereof without
notice other than such resolution.

3.5    SPECIAL MEETINGS

       Special meetings of the Board or any committee designated by the Board
may be called by or at the request of the Chairman of the Board, the President,
the Secretary or, in the case of special Board meetings, any one Director and,
in the case of any special meeting of any committee designated by the Board, by
the Chairman thereof. The person or persons authorized to call special meetings
may fix any place either within or without the state of Washington as the place
for holding any special Board or committee meeting called by them.

3.6    MEETINGS BY COMMUNICATIONS EQUIPMENT

       Members of the Board or any committee designated by the Board may
participate in a meeting of such Board or committee by, or conduct the meeting

3.8    WAIVER OF NOTICE

       3.8.1  IN WRITING

       Whenever any notice is required to be given to any Director under the
provisions of these Bylaws, the Articles of Incorporation or the Washington
Business Corporation Act, a waiver thereof in writing, signed by the person or
persons entitled to such notice and delivered to the corporation, whether before
or after the date and time of the meeting, shall be deemed equivalent to the
giving of 


                                       73
<PAGE>   16

such notice. Neither the business to be transacted at, nor the purpose of, any
regular or special meeting of the Board or any committee designated by the Board
need be specified in the waiver of notice of such meeting.

       3.8.2  BY ATTENDANCE

       A Director's attendance at or participation in a Board or committee
meeting shall constitute a waiver of notice of such meeting, unless the Director
at the beginning of the meeting, or promptly upon his or her arrival, objects to
holding the meeting or transacting business at such meeting and does not
thereafter vote for or assent to action taken at the meeting.

3.9    QUORUM

       A majority of the number of Directors fixed by or in the manner provided
in these Bylaws shall constitute a quorum for the transaction of business at any
Board meeting but, if less than a majority are present at a meeting, a majority
of the Directors present may adjourn the meeting from time to time without
further notice.

3.10   MANNER OF ACTING

       If a quorum is present when the vote is taken, the act of the majority of
the Directors present at a Board meeting shall be the act of the Board, unless

Incorporation or the Washington Business Corporation Act.

3.11   PRESUMPTION OF ASSENT

       A Director of the corporation who is present at a Board or committee
meeting at which any action is taken shall be deemed to have assented to the

business at such meeting, (b) the Director's dissent or abstention from the
action taken is entered in the minutes of the meeting, or (c) the Director
delivers written notice of the Director's dissent or abstention to the presiding
officer of the meeting before its adjournment or to the corporation within a
reasonable time after adjournment of the meeting. The right of dissent or
abstention is not available to a Director who votes in favor of the action
taken.

3.12   ACTION BY BOARD OR COMMITTEES WITHOUT A MEETING

       Any action which could be taken at a meeting of the Board or of any
committee created by the Board may be taken without a meeting if one or more

                                       74
<PAGE>   17

written consents setting forth the action so taken are signed by each of the
Directors or by each committee member either before or after the action is taken
and delivered to the corporation. Action taken by written consent of Directors
without a meeting is effective when the last Director signs the consent, unless
the consent specifies a later effective date. Any such written consent shall be
inserted in the minute book as if it were the minutes of a Board or a committee
meeting.

3.13   RESIGNATION

       Any Director may resign at any time by delivering written notice to the
Chairman of the Board, the President, the Secretary or the Board. Any such
resignation is effective upon delivery thereof unless the notice of resignation
specifies a later effective date and, unless otherwise specified therein, the
acceptance of such resignation shall not be necessary to make it effective.

3.14   REMOVAL

       Any Director or the entire Board may be removed for cause by the holders
of not less than two-thirds of the shares entitled to elect the Director or
Directors whose removal is sought. Such action may only be taken at a special
meeting of the shareholders called expressly for that purpose, providing that
notice of the proposed removal, which shall include a statement of the charges
alleged against the Director, shall have been duly given to the shareholders
together with or as a part of the notice of the meeting.

       Where a question of the removal of a Director for cause is to be
presented for shareholder consideration, an opportunity must be provided to such
Director to present his or her defense to the shareholders by a statement which
must accompany or precede the notice of the special meeting of shareholders or,
if provided to shareholders prior to the notice of the special meeting, the
initial solicitation of proxies seeking authority to vote for the removal of
such Director for cause. If not provided, then such proxies may not be voted for
removal. The Director involved shall be served with notice of the meeting at
which such action is proposed to be taken together with a statement of the
specific charges and shall be given an opportunity to be present and to be heard
at the meeting at which his or her removal is considered.

       The vacancy created by the removal of a Director under this Section 3.14
shall be filled only by a vote of the holders of two-thirds of the shares then
entitled to elect the Director removed. Such vote may be taken at the same
meeting at which the removal of such Director was accomplished, or at such later
meeting, regular or special, as the shareholders may decide.

       Subject to the provisions of Section 3.14 hereof and unless the Articles
of Incorporation provide otherwise, any vacancy occurring on the Board may be
filled by the shareholders, the Board or, if the Directors in office constitute
fewer than a quorum, by the affirmative vote of a majority of the remaining
Directors. Any vacant office held by a Director elected by the holders of one or
more classes or series of shares entitled to vote and be counted collectively
thereon shall be filled only by the vote of the holders of such class or series
of shares. A Director elected to fill a vacancy shall serve only until the next
election of Directors by the shareholders.

       In addition to any committees appointed pursuant to this Section 3.16,

present shall be the act of the committee.

       Each person who was, is or is threatened to be made a named party to or
is otherwise involved (including, without limitation, as a witness) in any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative and whether formal or informal
(hereinafter a "proceeding"), by reason of the fact that he or she is or was a
Director or officer of the corporation or, that being or having been such a
Director or officer or an employee of the corporation, he or she is or was
serving at the request of the corporation as a Director, officer, partner,
trustee, employee or agent of another corporation or of a partnership, joint
venture, trust, employee benefit plan or other enterprise (hereinafter an
"indemnitee"), whether the basis of a proceeding is alleged action in an
official capacity as such a Director, officer, partner, trustee, employee or
agent or in any other capacity while serving as such a Director, officer,
partner, trustee, employee or agent, shall be indemnified and held harmless by
the corporation against all expense, liability and loss (including counsel fees,
judgments, fines, ERISA excise taxes or penalties and amounts to be paid in
settlement) actually and reasonably incurred or suffered by such indemnitee in
connection therewith, and such indemnification shall continue as to an
indemnitee who has ceased to be a Director, officer, partner, trustee, employee
or agent and shall inure to the benefit of the indemnitee's heirs, executors and
administrators. Except as provided in subsection 10.2 of this Section with
respect to proceedings seeking to enforce rights to indemnification, the
corporation shall indemnify any such indemnitee in connection with a proceeding
(or part thereof) initiated by such indemnitee only if a proceeding (or part
thereof) was authorized or ratified by the Board. The right to indemnification
conferred in this Section shall be a contract right.

10.2   RESTRICTIONS ON INDEMNIFICATION

                                       83
<PAGE>   26

       No indemnification shall be provided to any such indemnitee for acts or
omissions of the indemnitee finally adjudged to be intentional misconduct or a
knowing violation of law, for conduct of the indemnitee finally adjudged to be
in violation of RCW 23B.08.310, for any transaction with respect to which it was
finally adjudged that such indemnitee personally received a benefit in money,
property or services to which the indemnitee was not legally entitled or if the
corporation is otherwise prohibited by applicable law from paying such
indemnification. Notwithstanding the foregoing, if RCW 23B.08.560 or any
successor provision of the Washington Business Corporation Act is hereafter
amended, the restrictions on indemnification set forth in this subsection 10.2
shall be as set forth in such amended statutory provision.

10.3   ADVANCEMENT OF EXPENSES

       The right to indemnification conferred in this Section shall include the
right to be paid by the corporation the expenses incurred in defending any
proceeding in advance of its final disposition (hereinafter an "advancement of
expenses"). An advancement of expenses shall be made upon delivery to the
corporation of an undertaking (hereinafter an "undertaking"), by or on behalf of
such indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial decision from which there is no further right to
appeal that such indemnitee is not entitled to be indemnified for such expenses
under this subsection 10.3.

10.4   RIGHT OF INDEMNITEE TO BRING SUIT

       If a claim under subsection 10.1 or 10.3 of this Section is not paid in
full by the corporation within sixty days after a written claim has been
received by the corporation, except in the case of a claim for an advancement of
expenses, in which case the applicable period shall be twenty days, the
indemnitee may at any time thereafter bring suit against the corporation to
recover the unpaid amount of the claim. If successful in whole or in part, in
any such suit or in a suit brought by the corporation to recover an advancement
of expenses pursuant to the terms of an undertaking, the indemnitee shall be
entitled to be paid also the expense of prosecuting or defending such suit. The
indemnitee shall be presumed to be entitled to indemnification under this
Section upon submission of a written claim (and, in an action brought to enforce
a claim for an advancement of expenses, where the required undertaking has been
tendered to the corporation) and thereafter the corporation shall have the
burden of proof to overcome the presumption that the indemnitee is so entitled.

10.5   PROCEDURES EXCLUSIVE

                                       84
<PAGE>   27

Corporation Act.

10.6   NONEXCLUSIVITY OF RIGHTS

       The right to indemnification and the advancement of expenses conferred in
this Section shall not be exclusive of any other right which any person may have
or hereafter acquire under any statute, provision of the Articles of
Incorporation or Bylaws of the corporation, general or specific action of the
Board, contract or otherwise.

and any Director, officer, partner, trustee, employee or agent of the

corporation would have the power to indemnify such person against such expense,
liability or loss under the Washington Business Corporation Act. The corporation
may enter into contracts with any Director, officer, partner, trustee, employee
or agent of the corporation in furtherance of the provisions of this Section and
may create a trust fund, grant a security interest or use other means
(including, without limitation, a letter of credit) to ensure the payment of
such amounts as may be necessary to effect indemnification as provided in this
Section.

10.8   INDEMNIFICATION OF EMPLOYEES AND AGENTS OF THE CORPORATION


       The corporation may, by action of the Board, grant rights to
indemnification and advancement of expenses to employees and agents or any class
or group of employees and agents of the corporation (a) with the same scope and
effect as the provisions of this Section with respect to the indemnification and
advancement of expenses of Directors and officers of the corporation; (b)
pursuant to rights granted pursuant to, or provided by, the Washington Business
Corporation Act; or ) as are otherwise consistent with law.

10.9   PERSONS SERVING OTHER ENTITIES

       Any person who, while a Director, officer or employee of the corporation,
is or was serving as a Director or officer of another foreign or domestic
corporation of which a majority of the shares entitled to vote in the election
of its Directors is held

arising from the possibility of a Change in Control of the Company, as defined
in Schedule A attached hereto.

                                   AGREEMENTS

<PAGE>   2

     4.   BENEFITS UPON CHANGE IN CONTROL

     Executive shall be entitled to the following payments and benefits
following a Change in Control, whether or not a Termination occurs:

          (A) SALARY AND BENEFITS. Executive shall (i) receive an annual base
salary no less than the Executive's annual base salary in effect immediately

of the three annual bonuses paid to Executive in the three years prior to the
Change in Control, and (ii) be entitled to participate in all employee expense
reimbursement, incentive, savings and retirement plans, practices, policies and
programs (including any Company plan qualified under Section 401(a) of the Code)
available to other peer executives of the Company and its Subsidiaries, but in
no event shall the benefits provided to Executive under this item (ii) be less
favorable, in the aggregate, than the most favorable of those plans, practices,
policies or programs in effect immediately prior to the date that the Change in
Control occurs.

          (B) WELFARE PLAN BENEFITS. The Company shall at the Company's expense
(except for the amount, if any, of any required employee contribution which
would have been necessary for Executive to contribute as an active employee
under the plan or program as in effect on the date of the Change in Control)
continue to cover Executive (and his or her dependents) under, or provide
Executive (and his or her dependents) with insurance coverage no less favorable
than, the Company's life, disability, health, dental and any other employee
welfare benefit plans or programs, as in effect on the date of the Change in
Control (such benefits, the "Welfare Benefits").

          (C) DEATH OF EXECUTIVE. In the event of Executive's death prior to
Termination, but while employed by the Company or any Subsidiary, his or her
spouse, if any, or otherwise the personal representative of his or her estate
shall be entitled to receive (i) Executive's salary at the rate then in effect
through the date of death, as provided under the Company's pay policy, (ii) any

<PAGE>   3

Disability, (iii) payments under the Company's short and long term disability
plans following the determination of Disability, and (iv) Welfare Benefits for a
period of two (2) years following the determination of Disability.

          (E) CAUSE; UPON EXPIRATION OF THIS AGREEMENT; OTHER THAN FOR GOOD

provided under the Company's pay policy, and (ii) any Accrued Benefits for the
periods of service prior to the date of such termination.

          (F) WITHHOLDING. All payments under this Section 4 are subject to
applicable federal and state payroll withholding or other applicable taxes.

     5.   PAYMENTS AND BENEFITS UPON TERMINATION

         Executive shall be entitled to the following payments and benefits
following Termination:

                  (A) TERMINATION PAYMENT. In recognition of past services to
the Company by Executive, the Company shall make a lump sum payment in cash to
Executive as severance pay equal to _____ times the sum of: (i) Executive's
annual base salary in effect immediately prior to the date that either a Change
in Control shall occur or such date of Termination, whichever salary is higher,
provided that if Executive is a part-time employee on the date of Termination
then Executive's base salary in effect immediately prior to the date of
Termination shall be used in calculating the payment to which Executive may be
entitled under this Section 5(a); plus (ii) a percentage of Executive's annual
base salary specified in subparagraph (i) above, which percentage is equal to
the percentage bonus paid to Executive for the fiscal year ended immediately
prior to the Change in Control; provided, however, that if Termination occurs
prior to the determination of such percentage for a fiscal year that has ended
or if Executive has not received a percentage bonus in the previous year, such
percentage shall be ten percent (10%). All payments under this Section 5(a) (the
"Termination Payments") shall be paid within ten (10) business days following
the date of Termination.

                  (B) CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY.
Notwithstanding the foregoing, if all or any portion of the Termination Payments
either alone or together with all other payments and benefits which Executive
receives or is then entitled to receive (pursuant to this Agreement or
otherwise) from the Company or any Subsidiary (all such payments and benefits,
including the Termination Payments, the "Termination Benefits"), would
constitute a Parachute Payment, then the Payments to Executive under Section
5(a) shall be increased (such increase, a "Gross-Up Payment"), but only to the
extent necessary to ensure that, after payment by Executive of all taxes
(including 


                                       89
<PAGE>   4

any interest or penalties imposed with respect to such taxes), including,
without limitation, any income taxes and Excise Tax imposed upon the Gross-Up
Payment, Executive retains an amount of the Gross-Up Payment equal to the Excise
Tax imposed upon the Termination Benefits. The foregoing calculations shall be
made, at the Company's expense, by the Company and Executive. If no agreement on
the calculations is reached within thirty (30) business days after the date of
Termination, then the accounting firm which regularly audits the financial
statements of the Company (the "Auditors") shall review the calculations. The
determination of such firm shall be conclusive and binding on all parties and
the expense for such accountants shall be paid by the Company. Pending such
determination, the Company shall continue to make all other required payments to
Executive at the time and in the manner provided herein and shall pay the
largest portion of such payments and benefits that, in the Company's reasonable
judgment, may be paid without triggering the Excise Tax.

          As a result of the uncertainty in the application of Section 4999 of
the Code, it is possible that Termination Payments or Gross-Up Payments will
have been made by the Company which should not have been made (an "Overpayment")
or that additional Gross-Up Payments which will not have been made by the
Company should have been made (an "Underpayment"). If it is determined by the
Company and Executive, or, if no agreement is reached by the Company and
Executive, the Auditors, that an Overpayment has been made, such Overpayment
shall be treated for all purposes as a loan to Executive which Executive shall
repay to the Company, together with interest at the applicable federal rate
provided for in section 7872(f)(2) of the Code. In the event that the Company
and Executive, or, if no agreement is reached by the Company and Executive, the
Auditors, determine that an Underpayment has occurred, such Underpayment shall
promptly be paid by the Company to or for the benefit of Executive, together
with interest at the applicable federal rate provided for in section
7872(f)(2)(A) of the Code. The Company and Executive shall give each other
prompt written notice of any information that could reasonable result in the
determination that an Overpayment or Underpayment has been made.

          (C)  ACCRUED BENEFITS. The Company shall make a lump sum payment in
cash to Executive in the amount of any Accrued Benefits for the periods of
service prior to the date of Termination.

          (D)  WELFARE PLAN BENEFITS. The Company shall at the Company's expense
(except for the amount, if any, of any required employee contribution which
would have been necessary for Executive to contribute as an active employee
under the plan or program as in effect on the date of Termination) continue to
cover Executive (and his or her dependents) under, or provide Executive (and his
or her dependents) with Welfare Benefits (as in effect on the date of the Change
in Control or, at the option of Executive, on the date of Termination) for a
period of one year following the date of Termination (or, at the Company's
option, in lieu of providing such Welfare Benefits, a 

                                       90
<PAGE>   5

lump sum cash payment may be made which will equal the then-present value of the
cost to the Company of such Welfare Benefits); provided, however, that if
Executive is provided by another employer during such one-year period with
benefits substantially comparable to the benefits provided by one or more of
such plans or programs, the benefits provided by the Company shall, unless a

                             COMPENSATION-ROYALTIES

3.1  For the rights, privileges and license granted hereunder, LICENSEE shall
pay royalties to LICENSOR in the manner hereinafter provided to the end of the
term of the Licensed Patent Rights on a country-by-country basis or until this
Agreement shall be terminated as hereinafter provided, whichever occurs first.
LICENSEE agrees to pay to LICENSOR a royalty of [ * ] on the amount of annual
Net Sales of Licensed Products that are less than or equal to [ * ] and a
royalty of [ * ] on the amount of annual Net Sales of Licensed Products that
exceed [ * ]. For sales in any country in which no Licensed Patent Rights exist,
such royalty shall be reduced [ * ] on the amount of annual Net Sales of
Licensed Products incorporating, based upon or made by employing the Licensed
Material or the technology described in the Licensed Patent Rights.

3.2  Notwithstanding the foregoing, if LICENSEE is required to pay royalties to
an unaffiliated third party(ies) for sales of Licensed Products for which
payments are also due to LICENSOR ("Third Party Royalties"), then the royalties
to be paid by LICENSEE to LICENSOR shall be reduced by the amount that the sum
of the LICENSOR's royalty percentage and Third Party royalty percentage are in
excess of [ * ] of Net Sales of Licensed Products, but in no event shall the
LICENSOR'S royalty percentage be reduced to less than [ * ].

3.3  No multiple royalties shall be payable because any Licensed Product, its
manufacture, use, lease or sale are or shall be covered by multiple claims or
more than one Licensed Patent Right licensed under this Agreement.

     (c)  The sum of [ * ] for the first Phase II clinical trial, or equivalent
          in a foreign country, initiated by LICENSEE or one of its sublicensees
          for a Licensed Product (Phase I/II or equivalent in a foreign country
          will be considered a Phase I trial);

     (d)  The sum of [ * ] for the first Phase III clinical trial, or equivalent
          in a foreign country, initiated by LICENSEE or one of its sublicensees
          for a Licensed Product for which a Phase II clinical trial was
          initiated and, consequently, a milestone payment was made to LICENSOR
          pursuant to paragraph 3.4(c);

     (e)  The sum of [ * ] for the first Phase III clinical trial, or equivalent
          in a foreign country, initiated by LICENSEE or one of its sublicensees
          for a Licensed Product for which no Phase II clinical trial was
          initiated and, consequently, no milestone payment was made to LICENSOR
          pursuant to paragraph 3.4(c); and

     (f)  The sum of [ * ] for the first Product Licensing Application, or
          equivalent in a foreign country, approved for LICENSEE's or one of its
          sublicensee's Licensed Product.

3.7  If LICENSEE grants a sublicense to the Licensed Patent Rights or the
Licensed Materials to a third party, for value other than royalties based on
sales of Licensed Products, LICENSEE shall pay LICENSOR [ * ] of all proceeds
paid to LICENSEE in consideration for such grant of a sublicense, including any
premium paid over the market value of the LICENSEE's common stock by a
sublicensee in connection with an equity purchase, but excluding such royalties
paid to LICENSEE in connection therewith, up to a maximum of [ * ] per year in
the year that such proceeds are paid to LICENSEE ("Non-Royalty Fees"). Any such
payment shall be made within thirty (30) days after receipt of such Non-Royalty
Fees by LICENSEE. Notwithstanding the foregoing, in no event shall LICENSEE: a)
be obligated to pay LICENSOR a share of any proceeds that LICENSEE receives from
a third party as research and development funding, milestone payments, or equity
purchase, other than any premium paid on an equity purchase; or b) enter into a
paid-up sublicense to Licensed Patent Rights or Licensed Materials with a third
party without the written consent of LICENSOR.

3.8  In the event that LICENSEE transfers or otherwise sublicenses Licensed
Patent Rights or Licensed Materials to a third party in combination with
patent(s) and/or other right(s) of a third party(ies) and LICENSEE is due and
receives Non-Royalty Fees, then LICENSEE shall pay LICENSOR an equitable portion
of such Non-Royalty Fees as determined by the good faith negotiations of
LICENSEE and LICENSOR.

of Use, LICENSOR shall negotiate with LICENSEE in good faith to reach agreement
on commercially reasonable terms for a sublicense to such Optioned Field(s) of
Use. Upon notification to LICENSOR by a third party of an intent to acquire
license rights to an optioned Field of Use, LICENSOR shall provide LICENSEE
written notification of such notice, and LICENSEE, at its own discretion, shall
have the option to negotiate with LICENSOR in good faith for a period of at
least sixty (60) days from the date of such notification ("Option Period") to
reach agreement on commercially reasonable terms for a sublicense to LICENSEE to
such Optioned Field(s) of Use. If LICENSEE elects not to negotiate, or if the
parties do not reach agreement during the Option Period, then LICENSOR may grant
a sublicense in respect of such Optioned Field(s) of Use to the Third Party on
terms that are no more favorable than those that were last offered by LICENSOR
to LICENSEE during the Option Period. The License Option shall expire one (1)
year from the Effective Date and may be renewed at LICENSEE's sole discretion
for subsequent one (1) year periods at the rate of [ * ] per year, reduced pro
rata in proportion to the number of Optioned Fields of Use which have previously
been sublicensed either to LICENSEE or to third parties.

                           RECORD KEEPING AND REPORTS

5.1  LICENSEE agrees to keep accurate records in sufficient detail to enable the
royalties payable by LICENSEE to LICENSOR hereunder to be determined, and agrees
to permit said records to be examined from time to time during the life of this
Agreement, and for one (1) year after the expiration and termination of this
Agreement, at reasonable intervals (but not more than once per calendar year) by
an independent auditor mutually agreeable to the parties, during normal business
hours, and to the extent necessary to verify the reports and payments required
hereunder. Such auditor shall only disclose to LICENSOR whether or not royalties
payable hereunder have been accurately computed and paid, and no other
information. In the event any such audit reveals an underpayment, LICENSEE shall
promptly remit the deficiency to LICENSOR. In the event any such audit reveals
an overpayment, the excess shall be credited against any future payments due to
LICENSOR hereunder.

5.2  LICENSEE agrees to furnish LICENSOR with written Reports within two (2)
months of the termination of each calendar quarter (i.e., such written Reports
shall be due as in Paragraph 3.3 supra) setting forth separately by model number

hereunder during the preceding calendar quarter and the royalties due thereon.
Each such Report shall be accompanied by a copy of any sub-sublicensee's Report
received subsequent to LlCENSEE's prior Report and prior to LlCENSEE's current
Report.

5.3  LICENSOR shall maintain in confidence, and shall not disclose to any third
party or use for any purpose not expressly authorized by this Agreement, all
information provided to LICENSOR and/or its auditor pursuant to this Article V
and to Article VII. LICENSOR shall obtain written agreement from LICENSOR's
auditor who shall inspect LICENSEE's records pursuant to Article 5.1, for
LICENSEE's benefit, to be bound by the foregoing confidentiality obligation.
Such confidentiality obligation shall survive any termination or expiration of
this Agreement. Notwithstanding the foregoing, the confidentiality obligation
shall not extend to the disclosure of data, documents or information to
judicial, governmental or other official agencies, or in accordance with common
practice, to the extent that such disclosure is required by any applicable
securities laws or self regulatory agencies.

                                   ARTICLE VI

                                  PATENT RIGHTS

6.1  LICENSOR shall, in the first instance, have the sole and exclusive right to
file any and all patent applications, both foreign and domestic, falling within
the scope of this Agreement; and LICENSOR shall be responsible for all costs,
fees and expenses incurred in connection with the filing, prosecution and
maintenance of any such patent application and the maintenance of any patent
issuing thereon. Any such patent shall be included within this Agreement as part
of the Licensed Patent Rights.

6.2  LICENSOR shall notify LICENSEE of the issuance of any Licensed Patent
Rights, and any expiration, lapse, revocation, surrender, invalidation or
abandonment of any Licensed Patent Rights.

6.3  If, at any time during the term of this Agreement, LICENSOR elects not to
file a patent application or to abandon any pending patent application or any
patent issued thereon, either foreign or domestic, it shall notify LICENSEE of
that decision at least two (2) months prior to any deadline for filing any
response or taking any other action necessary to file or maintain any such
application and/or patent in existence; and, thereafter, LICENSEE shall have the
right and option to participate, together with other licensees to such patent
application or issued patent, in the filing or prosecution of any such patent
application and/or the maintenance of any such patent, at LICENSEE's expense;
and, any patent issuing therefrom shall be exclusively licensed to LICENSEE in
the Field of Use and any Optioned Fields of Use as to which LICENSEE has
exercised its option pursuant to Article IV on a royalty-free basis.

7.1  LICENSEE, during the entire term of this Agreement, shall utilize
commercially reasonable efforts in proceeding with the development, manufacture,
sale and commercial exploitation of Licensed Product(s), and in creating a
supply and demand for same; provided, however, that LICENSEE shall be entitled

9.1  This Agreement, and the rights, privileges and license granted herein,
shall be in force from the Effective Date hereof and shall remain in full force
and effect thereafter until the last to expire of Licensed Patent Rights unless
sooner terminated in accordance with the provision set forth herein below. It
is, however, understood by the parties hereto that LlCENSEE's obligation to pay
royalties to LICENSOR under this Agreement shall terminate in the event of a
judicial determination that no portion of such Licensed Patent Rights are valid,
infringed and/or enforceable by a decision of a tribunal of competent authority
where such decision is final or by lapse of time becomes final and unappealable.

9.2  LICENSEE may terminate this Agreement and concomitant future obligations
upon thirty (30) days written notice to LICENSOR.

9.3  If LICENSEE shall cease to carry on its business, this Agreement shall
terminate upon notice by LICENSOR.

9.4  Should LICENSEE fail to make any payment whatsoever due and payable to
LICENSOR hereunder, LICENSOR shall have the right to terminate this Agreement
effective on thirty (30) days notice, unless LICENSEE shall make all such
payments to LICENSOR within said thirty (30) day period. Upon the expiration of
the thirty (30) day

period, if LICENSEE shall not have made all such payments to LICENSOR, the
rights, privileges and license granted hereunder shall automatically terminate.

9.5  Upon any material breach or default of this Agreement by LICENSEE other
than those occurrences set out in Articles 9.3 and 9.4 hereinabove, LICENSOR
shall have the right to terminate this Agreement and the rights, privileges and
license granted hereunder effective on sixty (60) days notice to LICENSEE. Such
termination shall become automatically effective unless LICENSEE shall have
cured any such material breach or default prior to the expiration of the sixty
(60) day period. In the event that LICENSOR asserts a breach of this Agreement
under Article 7.1, this Agreement shall remain in full force and effect until
the matter is resolved by the parties themselves or under arbitration as
provided for under Article 18.

                            ON HAND UPON TERMINATION

10.1 In the event of any termination of this Agreement, LICENSEE and its
sub-licensees shall have the right to use or sell all the Licensed Products on
hand at the time of such termination, provided that LICENSEE shall be obligated
to pay to the LICENSOR a royalty on such sales as set forth in this Agreement
if, at that time, there remains in existence any of Licensed Patent Rights
covering the manufacture, use or sale of such Licensed Product(s).

                                   ARTICLE XI

                               PATENT ENFORCEMENT

11.1 If LICENSEE shall have supplied LICENSOR with written evidence
demonstrating infringement of the Licensed Patent Rights by a third party,
LICENSEE may, by written notice, request LICENSOR to take steps to assert such
Licensed Patent Rights against such infringing product. LICENSOR shall within
six (6) months of the receipt of such notice either (a) cause such infringement
to terminate or (b) initiate and continue legal proceedings against the
infringer, or pursue other equivalent legal or patent remedies. If LICENSOR
fails to take either of the actions specified in clause (a) or (b) above,
LICENSEE may, upon notice to LICENSOR, discontinue making royalty payments to
LICENSOR that are due hereunder, and have further royalty payments waived by
LICENSOR until LICENSOR in good faith takes and continues such action, at which
time only future royalties shall be due. Notwithstanding the foregoing, if the
infringement ceases at any time, TGC's obligations shall continue at full force
from the time that infringement ceases.

11.2 In the event LICENSOR fails to terminate the infringement within the six
(6) months of written notification from LICENSEE informing LICENSOR of an
alleged infringement, and does not institute litigation against the infringer
for that purpose within such period, then LICENSEE shall have the right to bring
an action against the infringer for 

                                      111
<PAGE>   12

that purpose. LICENSOR shall cooperate fully with LICENSEE, at LICENSEE's
expense, in connection with any such action. Such cooperation shall include
(without limitation) LICENSOR's permitting LICENSEE to bring the action in
LICENSOR's name and LICENSOR's executing any consents or assignments necessary
or useful to permit LICENSEE to enforce the Licensed Patent Rights against the
infringer. LICENSEE shall be entitled to deduct all expenses incurred by it in
connection with any such action from the royalties and other amounts that would
otherwise be payable to LICENSOR hereunder; provided that to the extent any
amounts are finally awarded to LICENSEE in such action or are paid to LICENSEE
in settlement thereof, such amounts shall be paid over to LICENSOR until all
amounts so withheld have been repaid. Any amounts so awarded or paid in
settlement in excess of the amounts so withheld shall be retained by LICENSEE.

existence or nature of this Agreement, in any news, publicity release,
advertisement or other public disclosure, without the express prior written
approval of the other party. Notwithstanding the foregoing, each party hereby
consent to references to it (1) in such reports or documents sent to
stockholders or filed with or submitted to any governmental regulatory agencies
or bodies or stock exchanges or as may be required to obtain investment capital,
or (2) pursuant to any requirements of applicable law or governmental
regulations, provided that, in the event of any such disclosure, the party
making such disclosure shall afford the other party the prior opportunity to
review the text of such disclosure, the other party shall promptly respond to
the disclosing party, and the disclosing party shall use its best efforts to
comply with any reasonable requests by the other party regarding changes.

13.1 No omission or delay of either party hereto in requiring due and punctual
fulfillment of the obligations of the other party hereto shall be deemed to
constitute a waiver by such party of its rights to require such due and punctual
fulfillment, or of any other of its remedies hereunder.

best of its knowledge, it is the exclusive licensee of the Children's Hospital

rights of third parties; or,

     iii) an obligation to bring or prosecute actions or suits against third
parties for infringement.

including, but not limited to, any amounts payable by LICENSOR to its
licensor(s) of the Licensed Patent Rights or the Licensed Materials or other
persons or entities having rights in respect of the Licensed Patent Rights or
the Licensed Materials.

16.3 In the event of any claim for which indemnification will be sought pursuant

prompt written notice of such claim. The indemnifying party shall have the sole

writing in advance. The indemnified party will cooperate fully with the
indemnifying party, at the indemnifying party's expense, in connection with the

                         ARTICLE 6 - PATENT PROSECUTION

     6.1 UNIVERSITY has or shall apply for, seek prompt issuance of and maintain
during the term of this Agreement the PATENT RIGHTS in the United States and in
such foreign countries as may be designated by LICENSEE within a reasonable time

opportunity to advise and cooperate with UNIVERSITY in the prosecution, filing
and maintenance of such patents.

     6.2 All fees and costs, including attorneys' fees, relating to the filing,
prosecution and maintenance of the PATENT RIGHTS shall be the responsibility of
LICENSEE, whether incurred prior to or after the date of this Agreement and
payments by LICENSEE therefore shall not be creditable against royalties. Such
fees and costs incurred by UNIVERSITY prior to the date hereof will be payable

UNIVERSITY to LICENSEE.

                        ARTICLE 7 - INFRINGEMENT ACTIONS

shall not be obligated, to prosecute at its own expense all infringements of the
PATENT RIGHTS and, in furtherance of such right, UNIVERSITY hereby agrees that
LICENSEE may include UNIVERSITY as a party plaintiff in any such suit, without
expense to UNIVERSITY. The total cost of any such infringement action commenced
or defended solely by LICENSEE shall be borne by LICENSEE and LICENSEE shall
keep any recovery or damages for past infringement derived therefrom subject to
payment of royalties thereon at the rate established in Article 4.1(b), after
application of the costs incurred by LICENSEE in prosecuting such infringement
actions, including legal fees. LICENSEE may, for such purposes, use the name of
UNIVERSITY as party plaintiff. Notwithstanding the above, LICENSEE's right to
bring such an infringement action shall remain in effect only for so long as the
license granted herein remains exclusive.

     7.3 If within six (6) months after having been notified of any alleged
infringement, LICENSEE shall have been unsuccessful in persuading the alleged
infringer to desist and shall not have brought and shall not be diligently
prosecuting an infringement action, or if LICENSEE shall notify UNIVERSITY at
any time prior thereto of its intention not to bring suit against any alleged
infringer, then, and in those events only, UNIVERSITY shall have the right, but
shall not be obligated, to prosecute at its own expense any infringement of the
PATENT RIGHTS, and UNIVERSITY may, for such purposes, use the name of LICENSEE
as party plaintiff. No settlement, consent judgment or other voluntary final
disposition of the suit may be entered into by either party without the

     regulations by its employees, agents and invitees. Lessor's failure to
     enforce any of such rules and regulations against Lessee or any other
     Lessee shall not be deemed to be a waiver of same.

8.   MAINTENANCE AND REPAIRS.

          a. LESSEE OBLIGATIONS. Subject to the provisions of Exhibit F. by
     entry hereunder, Lessee accepts the Premises as being in good and sanitary
     order, condition and repair. Subject to the provisions of section 8(b)
     Lessee shall, at its expense, keep, maintain and preserve the Premises in
     first class condition and repair, and shall make all repairs to the
     Premises and every part thereof. Lessee shall, upon the expiration or
     sooner termination of the term hereof, surrender the Premises to Lessor in
     the same condition as when received, usual and ordinary wear and tear and
     damage by casualty excepted. Lessee shall not alter, remodel, improve,
     repair, decorate or paint the Premises or any part thereof without first
     obtaining the prior written permission of Lessor.

          b. LESSOR OBLIGATIONS. Notwithstanding Section 8a, Lessor shall repair
     and maintain the exterior and structural portions of the Building, the
     common areas of the Building including the garage and courtyard and the
     plumbing, heating, ventilating, air conditioning, elevator and (electrical
     and lighting systems furnished by Lessor; the costs of the foregoing shall
     be Operating Expenses, unless such maintenance and repairs are caused by
     the act, neglect or omission of Lessee, its agents, servants, employees or
     invitees, in which case Lessee shall pay to Lessor, as additional rent, the
     cost of such maintenance and repairs. Lessor shall not be liable for any
     failure to make any such repairs or to perform any maintenance unless such
     failure shall persist for an unreasonable time after written notice of the
     need of such repairs or maintenance is given to Lessor by Lessee. There
     shall be no abatement of rent and no liability of Lessor by reason of any
     injury to or interference with Lessee's business arising from the making of
     any repairs, alterations or improvements in or to any portion of the
     Building or the Premises or in or to fixtures, appurtenances and equipment
     therein. Lessee waives the right, if any, to make repairs at Lessor's
     expense under any law, statute or ordinance now or hereafter in effect.

9.   UTILITIES AND FEES. It is Lessor's policy that utilities and services be
     furnished as set forth in Exhibit E hereto. Lessor's failure to furnish any
     of such items due to matters outside Lessor's control shall not result in
     any liability to Lessor, Lessee shall not be entitled to any abatement or
     reduction of rent by reason of such failure, and no eviction of Lessee
     shall result from such failure. If Lessee uses more water or electrical
     power than is considered reasonable or normal by Lessor, Lessor may at its
     option require Lessee to pay, as additional rent, the cost, as fairly
     determined by Lessor and Lessee, incurred by such extraordinary usage. In
     addition, Lessor may install separate meter(s) for the Premises, at
     Lessee's sole expense, and Lessee thereafter shall pay all charges so
     metered.

10.  ADDITIONAL RENT AND MONTHLY OPERATING EXPENSE ADJUSTMENTS. Commencing on
     January 1. 1997 with regard to Lessor's Non-Controllable Operating
     Expenses' and commencing on January 1. 1998 with regard to Lessor's
     Controllable Operating Expenses for each calendar year during this Lease,
     or portion thereof, Lessee shall pay as Additional Rent its prorata share
     of the amount by which Operating Expenses for each year exceed the Base
     Year Operating Expenses. The Base Year Operating Expenses for "Lessor's
     Controllable Operating Expenses", as defined below, shall be 1997. The Base
     Year Operating Expenses for "Lessor's Non-Controllable Operating Expenses",
     as defined below, shall be 1996. Lessor shall estimate, from time to time,
     Lessee's payment amount. This estimated amount shall be divided into equal
     monthly installments, one payable with each installment of the Monthly
     Minimum Rent. As soon as practical following each calendar year, Lessor
     shall prepare an accounting of actual Operating Expenses incurred during
     the prior calendar year and such accounting shall reflect Lessee's '
     Percentage. If the Additional Rent paid by Lessee under this Section 10
     during the preceding calendar year was less than the actual amount of
     Lessee's Percentage of Operating Expenses, Lessor shall notify Lessee and
     Lessee shall pay such amount to Lessor within fifteen (15) days of receipt
     of such notice, notwithstanding Lessee's obligation to pay within fifteen
     (15) days. Lessee shall have sixty (60) days from receipt of such notice to
     contest the amount due; failure to so notify Lessor shall represent final
     determination of Lessee's share of Operating Expenses. If Lessee's 

                                      138
<PAGE>   3

     payments were greater than the actual amount due, then such overpayment
     shall be credited to Lessor to all present rent next due under this Section
     10. As of the date of this Lease. the total rentable square footage of the
     Building is 315,738 and Lessee's prorate share of Operating Expenses is
     1.495%. If the rentable square footage of the Building is increased or
     reduced during the Lease Term Lessee's prorate share shall be appropriately
     adjusted.

     For the purposes of this Paragraph 10, "Lessor's Controllable Operating
     Expenses" shall include, but not be limited to:

          All costs of management, operation and maintenance of the Premises,
          the building and the Land, including without limitation the following:

          capital items except that Expenses shall include the cost of any
          capital improvements made after completion of the Building as a
          labor-saving device or to effect other economies in the operation or
          maintenance of the building or made after the date of this Lease that
          are required under any governmental law or regulation, such costs to
          be amortized over their useful life, together with interest at a rate
          equal to the rate of interest publicly announced from time to time by
          Seattle First National Bank of Washington, Seattle, Washington, as its
          "prime interest rate" plus two percent (2%) per annum or such higher
          rate as may be paid by Lessor on funds borrowed for the purpose of
          constructing such capital improvements.

     For the purposes of this Paragraph 10, "Lessor's Non-Controllable Operating
     Expenses" shall include, but not be limited to:

     determination is made of Lessee's Percentage of Operating Expenses for the
     year in which this Lease expires or terminates, Lessee shall immediately
     pay any shortfall due. Conversely, any overpayment made shall be rebated by
     Lessor to Lessee, unless Lessee at that time is indebted to Lessor.

11.  LESSOR'S RESERVATIONS. Lessor reserves the right without liability to
     Lessee, but following commercially reasonable notice to Lessee: (a) to
     inspect the Premises, to show them to prospective Lessees, and if they are
     vacated, to prepare them for reoccupancy; (b) to retain at all times and to
     use in appropriate instances keys to doors within and into the Premises;
     (c) to make repairs, alterations, additions or improvements, whether
     structural or otherwise, in or about the building, and for such purposes to
     enter upon the Premises and during the continuance of any work, to close
     common areas and to interrupt or temporarily suspend building services and
     facilities, all without affecting any of Lessee's obligations hereunder, so
     long as the Premises are reasonably accessible; and (d) generally to
     perform any act relating to the safety, protection and preservation of the
     Premises or building. In all circumstances in which Lessor's activities and
     the activities of its agents and employees, affect Lessee's use or
     occupancy of the Premises and common areas, Lessor agrees to manage its
     activities in a professional manner which reasonably minimizes the impact
     on Lessee.

12.  POSSESSION. If Lessor does not deliver possession of the Premises at the
     Commencement Date of the term of this Lease, Lessee may give Lessor written
     notice of its intention to cancel this Lease if possession is not delivered
     within ninety (90) days after receipt of such notice by Lessor. Lessor
     shall not be liable for any damages caused by failure to deliver possession
     of the Premises and Lessee shall not be liable for any rent until such time
     as Lessor delivers possession. A delay 

                                      139
<PAGE>   4

     of possession shall not extend the termination date. If Lessor offers
     possession of the Premises or any portion thereof prior to the Commencement
     Date of the term of this Lease, and if Lessee accepts such early
     possession, then both parties shall be bound by all of the covenants and
     terms contained herein during such period of early possession including the
     payment of rent which shall be pro-rated accordingly and for the number of
     days of such early possession.

13.  ASSIGNMENT AND SUBLETTING. Lessee shall not either voluntarily or by
     operation of law assign, transfer, convey or encumber this Lease or any
     interest under it, or sublet to occupy or use the Premises without Lessor's
     prior written consent which shall not be unreasonably withheld. Lessor
     reserves the right to recapture the Premises or applicable portion thereof
     in lieu of giving its consent by notice given to Lessee within twenty (20)
     days after receipt of Lessee's written request or assignment or subletting.
     Such recapture shall terminate this Lease as to the applicable space
     effective on the prospective date of assignment or subletting, which shall
     be the last day of a calendar month and not earlier than sixty (60) days
     after receipt of Lessee's request hereunder. In the event that Lessor shall
     not elect to recapture and shall thereafter give its consent, Lessee shall
     pay Lessor a reasonable fee, not to exceed Five Hundred and No/100 Dollars
     ($500.00) to reimburse Lessor for processing costs incurred in connection
     with such consent. Lessor's consent shall not release or discharge Lessee
     from future liability under this Lease and shall not waive Lessor's right
     to consent to any future assignment or sublease. Any assignment or
     subletting without Lessor's consent shall be void and shall, at Lessor's
     option, constitute a default under this Lease. A transfer by the present
     majority shareholders of ownership or control of a majority of the voting
     stock of a corporate Lessee shall be deemed an assignment.

14.  ALTERATIONS. After obtaining the prior written consent of Lessor, Lessee
     may make minor alterations, additions and improvements in said Premises (so
     long as such alterations, additions or improvements are not visible from
     the exterior of the Premises) at its own expense. Lessee agrees to save
     Lessor harmless from any damage, loss, or expense arising therefrom and to
     comply with all laws, ordinances, rules and regulations. Upon termination
     of this Lease, all alterations, additions and improvements made in, to or
     on the Premises (including without limitation all electrical, lighting,
     plumbing, heating, air conditioning, and communications equipment and
     systems, doors, windows, partitions, drapery, carpeting, shelving,
     counters, and physically attach fixtures unless excluded by written
     agreement annexed hereto), shall remain upon and be surrendered as a part
     of the Premises; provided however, upon Lessor's request, made at the time
     Lessor grants its consent to the alterations Lessee shall on or before the
     end of the Lease Term promptly remove those additions, alterations, or
     improvements as may be specified by Lessor, and repair and restore the
     Premises to its original condition at Lessee's own expense. Lessee agrees
     to remind Lessor of this special provision in its request for approval.

15.  LIENS. Lessee shall keep the Premises free from any liens arising out of
     any work performed, materials furnished, equipment supplied, or
     obligations incurred by or on behalf of Lessee. No work performed, material
     furnished, equipment supplied or obligations incurred by or on behalf of
     Lessee shall be deemed to be for the immediate use and benefit of Lessor so
     that no mechanic's lien or other lien shall be allowed against Lessor's
     estate in the Premises. Lessee shall provide, at Lessee's own cost, a
     waiver of lien signed by any party (including the Lessee) who commences to
     perform work, furnish materials, or supply equipment to the Premises.
     Lessor does not authorize or consent to the performance of any work,
     furnishing of material or supply of equipment incurred by or on behalf of
     Lessee prior to Lessee providing Lessor with the signed waiver of lien
     referred to above. Lessor may require, at Lessee's own expense, a lien
     release and completion bond in an amount equal to either the actual
     contract price or one and one-half times the estimated cost of any
     improvements, additions or alterations in the Premises which Lessee desires
     to make, to insure Lessor against any liability for lien and to insure
     completion of the work.

16.  SIGNS. All signs or symbols placed by Lessee in the windows and doors of
     the Premises, or upon any exterior part of the building, shall be subject
     to Lessor's prior written approval. Prior to termination of this Lease,

     repair any damages caused by such removal.

     purposes for which Lessee has been using the Premises or if more than
     twenty five percent (25%) of the rentable square footage of the Premises
     shall be so taken, then either party, by written notice to the other, given
     at least thirty (30) days prior to the date that possession must be
     surrendered to the public authority, may terminate this Lease effective as
     of such surrender of possession. If any part of the building other than the
     Premises shall be so taken so as to render in Lessor's opinion the
     termination of this Lease beneficial to the remaining portion of the
     building, Lessor shall have the right within sixty (60) days of said taking
     to terminate this Lease upon thirty (30) days written notice to Lessee. In
     the event of any taking, whether whole or partial, Lessor shall be entitled
     to all awards, settlements, or compensation which may be given for the land
     and buildings. Lessee shall have no claim against Lessor for the value of
     any unexpired term of this Lease.

21.  INSOLVENCY. If Lessee shall be declared insolvent or bankrupt, or if
     Lessee's leasehold interest herein shall be levied upon or seized under
     writ of any court of law, or if a trustee, receiver or assignee be
     appointed for the property of Lessee, whether under operation of State or
     Federal statutes, then Lessor may, at its option, immediately, without
     notice (notice being expressly waived), terminate this Lease and take
     possession of said Premises, without, however, terminating Lessee's
     obligations under this Lease.

22.  DEFAULT AND RE-ENTRY. If Lessee fails to keep or perform any of the
     covenants and agreements herein contained, then the same shall constitute a
     breach hereof, and if Lessee has not remedied such breach within three (3)
     days after written notice thereof from Lessor if the breach is non-payment
     of rent or other charges, or within ten (10) days after written notice
     thereof from Lessor in the event of the breach of any other covenant,
     provided that if the default cannot reasonably be cured within that period
     Lessee shall have such longer period to cure the default as is reasonably
     necessary so lone as Lessee commences the work within the initial period
     and is diligently pursuing the cure of such default, then Lessor may, at
     its option, without further notice or demand:

     (a)  Cure such breach for the account and at the expense of Lessee and such
          expense shall be deemed additional rent due on the first of the
          following month. In addition, Lessor may terminate any future rights
          of Lessee under Paragraphs 1, 2 3 and or 5 of Exhibit G; or

     (b)  Re-enter the Premises, remove all persons therefrom, take possession
          of the Premises and remove all personal property therein at Lessee's
          risk and expense and ( 1 ) terminate this Lease, or (2) without
          terminating the Lease or in any way affecting the rights and remedies
          of Lessor or the obligations of Lessee, re-let the whole or any part
          of the Premises as agent


                                      142
<PAGE>   7

          for Lessee, upon such terms and conditions as Lessor may deem
          advisable. In either event, any moneys received from Lessee and any
          deposit or other amounts held by Lessor may first be applied by Lessor
          to any damages suffered by Lessor as a result of such default,
          including without limitation, costs and expenses incurred on re-entry
          and re-letting, any unamortized tenant improvements and commissions,
          cleaning, necessary repairs, restoration and alteration, and any
          commissions incurred on re-letting, and the balance of such amounts
          may be applied toward payment of other sums due to Lessor hereunder.
          In the event the Premises are re-let for Lessee's account, Lessee
          shall pay to Lessor monthly any deficiency; however, Lessor shall not
          be required to pay any excess to Lessee. Upon termination of this
          Lease or of Lessee's right to possession, Lessor has the right to
          recover from Lessee: (1) The worth of the unpaid rent that had been
          earned at the time of such termination; (2) The worth of the amount of
          the unpaid rent that would have been earned after the date of such
          termination; and (3) Any other amount, including court, attorney and
          collection costs, necessary to compensate Lessor. "The Worth," as used
          in Section (1) of this paragraph 22(b) is to be allowing interest at
          18% per year. "The Worth" as used for Section (2) of this paragraph
          22(b) is to be computed by discounting the amount at the discount rate
          of the Federal Reserve Bank of San Francisco at the time of
          termination. The above remedies of Lessor are cumulative and in
          addition to any other remedies now or hereafter allowed by law or
          elsewhere provided for in this Lease.

23.  REMOVAL OF PROPERTY. Any property of Lessee removed by Lessor in accordance
     with Section 22 above may be stored by Lessor or may be deposited on any
     area adjacent to the building at the sole risk and expense of Lessee and
     without any further responsibility of Lessor, and Lessor may at its sole
     discretion without removing said property or after removing said property,
     without obligation to do so and without notice to Lessee, sell or dispose
     of the same at public or private sale for the account of Lessee, in which
     event the proceeds therefrom may be applied by Lessor upon any indebtedness
     due from Lessee to Lessor. Lessee waives all claims for damages that may be
     caused by Lessor re-entering the Premises and removing or disposing of said
     property as herein provided.

24.  COSTS AND ATTORNEYS' FEES. In the event either party shall commence legal
     action to enforce any provision of this Lease, the court shall award to the
     prevailing party all reasonable attorneys' fees and all costs incurred in
     connection therewith, including fees and costs on appeal. Any action
     relating to this Lease shall be brought in the County in which the Premises
     are located or, at Lessor's election, in King County, Washington.

25.  SUBROGATION WAIVER. Lessor and Lessee each herewith and hereby release and
     relieve the other and waive its entire right of recovery against the other
     for loss or damage arising out of or incident to the perils of fire,
     explosion or any other perils described in the "all risk" insurance
     endorsement approved for use in the state in which the Premises are
     situated which occurs in, on or about the Premises, whether due to the
     negligence of either party, their agents, employees or otherwise.

26.  HOLDING OVER. If Lessee, with the express consent of Lessor, shall hold
     over after the expiration of the term of this Lease, Lessee shall remain
     bound by all the covenants and agreements herein, except that (a) the
     tenancy shall be from month-to-month and (b) the monthly rent to be paid by
     Lessee shall be determined by multiplying the monthly rent in effect
     immediately preceding such expiration times 150%. If Lessee holds
     possession of the Demised Premises after the expiration of the Lease
     without the express written consent of Lessor, Lessee shall remain bound by
     all the covenants and agreements herein, except that (a) the tenancy shall
     be from month-to-month and (b) the monthly rent to be paid by Lessee shall
     be determined by 



                                      143
<PAGE>   8

     multiplying the monthly rent in effect immediately preceding such
     expiration times 200%. Any such tenancy may be terminated as provided by
     Washington State law.

27.  SUBORDINATION AND ATTORNMENT; MORTGAGEE PROTECTION

     A.   SUBORDINATION-NOTICE TO MORTGAGEE. At the request of Lessor, Lessee
          shall promptly execute, acknowledge and deliver, all instruments which
          may be required to subordinate this Lease to any existing or future
          mortgages, deeds of trust and/or other security documents on or
          encumbering the Premises or on the leasehold interest held by Lessor,
          and to any extensions, renewals, or replacements thereof, provided
          that the mortgagee or beneficiary, as the case may be, shall agree to
          recognize this Lease in the event of foreclosure if Lessee is not in
          default at such time and provided that such instruments do not change
          the rights or obligations of Lessee under this Lease.

     B.   LESSEE'S CERTIFICATE. Lessee shall at any time and from time to time
          upon not less than seven (7) days prior written notice from Lessor
          execute, acknowledge and deliver to Lessor a statement in writing (a)
          certifying that this Lease is unmodified and in full force and effect
          (or, if mod)modified, stating the nature of such mod)modification and
          certifying that this Lease as so modified is in full force and effect
          and the date to which the rental and other charges are paid in
          advance, if any; and (b) acknowledging that there are not, to Lessee's
          knowledge, any uncured defaults on the part of the Lessor or Lessee
          hereunder, or specifying such defaults if any are claimed; and (c)
          setting forth the date of commencement of rents and expiration of the
          Lease Term hereof. Any such statement may be relied upon by any
          prospective purchaser or encumbrancer of all or any portion of the
          Premises of which the Premises are a part.

     C.   MORTGAGEE PROTECTION CLAUSE. Lessee agrees to notify any mortgagee
          and/or trust deed holders, by registered mail, with a copy of any
          notice of default served upon the Lessor, provided that prior to such
          notice Lessee has been not)notified in writing (by way of Notice of
          Assignment of Rents and Lease, or otherwise) of the addresses of such
          mortgagees and/or trust deed holders. Lessee further agrees that if
          Lessor shall have failed to cure such default, then the mortgagees
          and/or trust deed holders have thirty (30) days within which to cure
          such default or if such default cannot be cured within that time, then
          such additional times as may be necessary if within such thirty (30)
          days any mortgagee and/or trust deed holder has commenced and is
          diligently pursuing the remedies necessary to cure such default
          (including but not limited to commencement of foreclosure proceedings
          if necessary to affect such cure), in which event this Lease shall not
          be terminated if such remedies are being so diligently pursued.

28.  SURRENDER OF POSSESSION. Lessee shall, prior to the termination of this
     Lease or of Lessee's right to possession, remove from the Premises all
     personal property which Lessee is entitled to remove and those alterations,
     additions, improvements or signs which may be required by Lessor to be
     removed, pursuant to Section 14 above, and shall repair or pay for all
     damage to the Premises caused by such removal. All such property remaining
     and every interest of Lessee in the same shall be conclusively presumed to
     have been conveyed by Lessee to Lessor under this Lease as a bill of sale,
     without compensation, allowance, or credit to Lessee. Lessee shall upon
     termination of this Lease or of Lessee's right of possession, deliver all
     keys to Lessor and peacefully quit and surrender the Premises without
     notice, neat and clean, and in as good

                                      144
<PAGE>   9

     condition as when Lessee took possession, except for reasonable wear and
     tear and damage by casualty.

29.  LATE PAYMENT AND INTEREST. If any amount due from Lessee is not received in
     the office of Lessor on or before the third (3rd) business day following
     the date upon which such amount is due and payable, a late charge of five
     percent (5%) of said amount shall become immediately due and payable, which
     late charge Lessor and Lessee agree represents a fair and reasonable
     estimate of the processing and accounting costs that Lessor will incur by
     reason of such late payment. All past due amounts owing to Lessor under
     this Lease, including rent, shall be assessed interest at an annual
     percentage rate of eighteen percent (18%) from the date due or date of
     invoice, whichever is earlier, until paid.

30.  NOTICE. Any notice required to be given by either party to the other
     pursuant to the provisions of this Lease or any law, present or future,
     shall be in writing, and shall be deemed to have been duly given or sent if
     either delivered personally or three (3) business days after being
     deposited in the United States Mail, postage prepaid, registered or
     certified, return receipt requested, addressed to the Lessor at the address
     specified for the payment of rent under paragraph 3 of this Lease or to 2
     such other address as either party may designate to the other in writing
     from time to time:

     Targeted Genetics Corporation               Benaroya Capital Company, LLC
     1100 Olive Way, Suite 100                   1001 4th Avenue, Suite 4700
     Seattle, Washington 98101                   Seattle, WA 98154
     Atten: Director of Operations               (206) 343-4750

31.  NO WAIVER OR COVENANTS. Time is of the essence of this Lease. Any waiver by
     either party of any breach hereof by the other shall not be considered a
     waiver of any future similar or other breach.

32.  BINDING ON HEIRS SUCCESSORS AND ASSIGNS. The covenants and agreements of
     this Lease shall be binding upon the heirs, executors, administrators,
     successors and assigns of both parties hereto, except as hereinabove
     provided.

33.  LESSOR'S ASSIGNMENT. Lessor shall have the full right to assign this Lease,
     without any notice to Lessee, thereby relieving Lessor from all and any
     liabilities occurring after such assignment; provided however, that the
     assignee assumes all Lessor's responsibilities as set forth in this Lease.

34.  ENVIRONMENTAL, EMISSIONS; STORAGE' USE AND DISPOSAL OF WASTE:

     a. EMISSIONS. Lessee shall not (i) discharge, emit or permit to be
     discharged or emitted, any liquid, solid or gaseous matter, or any
     combination thereof, into the atmosphere, the ground or any body of water,
     which does or may pollute or contaminate the same, or does or may adversely
     affect the health or safety of persons, or the use or enjoyment of the
     Premises; nor (ii) transmit, receive or permit to be transmitted or
     received, any electromagnetic, microwave or other radiation in, on or about
     the Premises.

     b. STORAGE. IF, WITH or without violation of this Lease, Lessee possesses

                                      145
<PAGE>   10

     shall store the same in appropriate leak proof containers and/or areas
     which comply with all laws and all prudent practices.

     c. DISPOSAL OF WASTE. Lessee shall not keep any trash, garbage, waste or
     other refuse on the Premises except in sanitary containers and shall
     regularly and frequently remove same from the Premises. Lessee shall keep
     all such containers in a clean and sanitary condition. Lessee shall
     properly dispose of all sanitary sewage and shall not use the sewage system
     for the disposal of anything except sanitary sewage, nor in excess of
     capacity. Lessee shall not cause any obstruction in the sewage disposal
     system.

     d. COMPLIANCE OF LAW. Notwithstanding any other provision in the Lease to
     the contrary, Lessee shall comply with all Laws in complying with its
     obligations under this Lease, and in particular, Laws relating to the
     storage, use and disposal of Hazardous Substances (as defined below).

     e. INDEMNIFICATION FOR BREACH. Lessee shall defend, indemnify and hold
     Lessor, the Project and the holder of a trust deed or mortgage on the
     Project harmless from any loss, claim, liability or expense, including,
     without limitation, attorneys fees and costs, at trial and/or on appeal and
     review, arising out of or in connection with its failure to observe or
     comply with the provisions of this Section. This indemnity shall survive
     the expiration or earlier termination of the term of the Lease or the
     termination of Lessee's right of possession and be fully enforceable
     thereafter.

     f. INDEMNIFICATION REGARDING HAZARDOUS SUBSTANCES. In addition to the
     indemnity obligations contained elsewhere herein, Lessee shall indemnify,
     defend and hold harmless Lessor, the Premises, the Project, and the holder
     of a trust deed or mortgage on the Project, from and against all claims,
     losses, damages, monitoring costs, response costs, liabilities, and other
     costs expenses caused by, arising out of, or in connection with, the
     generation, release, handling, storage, discharge, transportation, deposit

     law or regulation related to protection of health or the environment as any
     of same may be amended from time to time, and/or by any rules and
     regulations promulgated thereunder. Such damages, costs, liability and
     expenses shall include such as are claimed by any regulating and/or

     successor of the Lessor named herein. This indemnity shall include (i)

     relief; (ii) the costs, expenses or losses resulting from any injunctive

     attorney's fees, incurred at, before and after any administrative

                                      146
<PAGE>   11

     g. INFORMATION. Lessee shall give prior written notice to Lessor of any
     use, whether incidental or otherwise, of Hazardous Substances on the
     Premises, and shall immediately deliver to Lessor a copy of any notice of
     any violation of any Law with respect to such use. Lessee shall also
     provide to Lessor, upon request, with any and all information regarding

          of Lessor in the Project, and Lessor shall have no other liability
          whatsoever.

     b.   (i) No partner, member, employee, affiliate, or manager of Lessor
          shall be sued or named as a party in any suit or action; (ii) No
          service of process shall be made against any partner, member,
          employee, affiliate, or manager of Lessor (except as may be necessary
          to secure jurisdiction of Lessor); (iii) No partner, member, employee,
          affiliate, or manager of Lessor shall be required to answer or
          otherwise plead to any service or process; (iv) No judgment may be
          taken against any partner, member, employee, affiliate, or manager of
          Lessor; (v) Any judgment taken against any partner, member, employee,

          hearing; and (vi) No writ of execution will ever be levied against the
          assets of any partner, member, employee, affiliate, or manager of

     Lessee that there are no promises, agreements, conditions, understandings,
     inducements, warranties, or representations, oral or written, express or

     shall not be mod)modified in any manner except by an instrument in writing
     executed by the parties.

                      STANDARDS FOR UTILITIES AND SERVICES

To Lease made on this __ day of__________ , 1996, between BENAROYA CAPITAL
COMPANY, LLC, a Washington limited liability company (the "Lessor") and TARGETED
GENETICS CORPORATION (the "Lessee").

     The following Standards for Utilities and Services are in effect. Lessor
reserves the right to adopt nondiscriminatory mod)modifications and additions
hereto.

     1. Non-attended automatic elevator facilities Monday through Friday, except
holidays, from 8 a.m. to 6 p.m., and have one elevator available at all other
times.

     2. Monday through Friday, except holidays, from 7 a.m. to 6 p.m., (and
other times for the sum of $10.00 per hour via override switches located on the
zoned thermostats in the Premises), ventilate the Premises and furnish air
conditioning or heating and undertake good faith efforts to maintain
temperatures of between 68 o and 75o in the Premises subject to extreme outside
temperatures. Lessee agrees to cooperate fully at all times with Lessor, and to
abide by all reasonable regulations and requirements which Lessor may prescribe
for the proper function and protection of said air conditioning system. Lessee
agrees not to connect any apparatus, device, conduit or pipe to the building
chilled and hot water air conditioning supply lines. Lessee further agrees that
neither Lessee nor its, employees, agents, visitors, licensees or contractors
shall at any time enter mechanical installations or facilities of the Building
or adjust, tamper with, touch or otherwise in any manner affect said
installations or facilities. The cost of maintenance and service calls to adjust
and regulate the air conditioning system shall be charged to Lessee if the need
for maintenance work results from either Lessee's adjustment of room thermostats
or Lessee's failure to comply with its obligations under this section. Such work
shall be charged at hourly rates equal to then-current journeymen's wages to air
conditioning mechanics.

     3. Electric current as required by the building standard office lighting
and fractional horsepower office business machines in an amount not to exceed
3.5 watts per square foot. Lessee agrees, should its electrical installation or
electrical consumption be in excess of the aforesaid quantity or extend beyond
normal business hours, to reimburse Lessor monthly for the measured consumption
at the average cost per kilowatt hour charged to the building during the period.
If a separate meter is not installed at Lessee's cost, such excess costs will be
established by an estimate agreed upon by Lessor and Lessee, and if the parties
fail to agree, as established by an independent licensed engineer. Lessee
further agrees not to connect any apparatus or devise with wires, conduits or
pipes, or the other means by which such services are supplied, for the purpose
of using additional or unusual amounts of such services without the prior
written consent of Lessor. Should Lessee use the same to excess, the refusal on
the part of Lessee to pay upon demand of Lessor the amount established by Lessor
for such excess charge shall constitute a breach of the obligation to pay rent
under this Lease and shall entitle Lessor to the rights therein granted for such
breach. At all times Lessee's use of electric current shall never exceed the
capacity of the feeders to the building or the risers or wiring installation and
Lessee shall not install or use or permit the installation or use of any
unusually high weight or high electrical consumption computer or electronic data
processing equipment in the Premises without the prior written consent of
Lessor.

     4. Provide janitor service to the Premises, provided the same are used
exclusively as offices, and are kept reasonably in order by Lessee, and if to be
kept clean by Lessee, no one other than persons 

                                      158
<PAGE>   23

approved by Lessor shall be permitted to enter the Premises for such purposes.
If the Premises are not used exclusively as offices, they shall be kept clean
and in order by Lessee, at Lessee's expense, and to the satisfaction of Lessor,
and by persons approved by Lessor. Lessee shall pay to Lessor the cost of
removal of any of Lessee's refuse and rubbish to the extent that the same
exceeds the refuse and rubbish usually attendant upon the use of the Premises as
of offices.

Lessor reserves the right to stop service of the elevator, plumbing,
ventilation, air conditioning and electric systems, when necessary, by reason of
accident or emergency or for repairs, alterations or improvements, in the
judgment of Lessor desirable or necessary to be made, until said repairs,
alterations or improvements, shall have been completed, and shall further have
no responsibility or liability for failure to supply elevator facilities,
plumbing, ventilation, air conditioning or electric service. It is expressly
understood and agreed that any covenants, express or implied, for Lessor to
furnish any service for the benefit of Lessee shall not be deemed breached if
Lessor is unable to furnish or perform the same by virtue of a strike or labor
trouble or any other cause whatsoever beyond Lessor's reasonable control. In all
circumstances in which Lessor's activities and the activities of its agents and
employees' affect Lessee's use or occupancy of the Premises and common areas
Lessor agrees to manage its activities in a professional manner which reasonably
minimizes the impact on Lessee.

         5. Lessee shall not use or install in the Premises any heat generating
equipment, except as specifically authorized herein, or installed pursuant to
the Work Letter Agreement, without Lessor's prior written consent. The inclusion
of this restriction is to ensure that the HVAC system is adequate to service the
Building and the various uses of tenants that occupy the Building.

improvements for the Expansion Space will be as negotiated by the two parties.
If the parties can't agree, then, the Monthly Minimum Rent shall be increased to
the then current fair market rent (the "New Rent") and Lessor shall provide the
same level of tenant improvements as are then being provided by landlords under
comparable leases. The New Rent shall be the average prevailing rental rate for
comparable space. The parties agree that for purposes of determining the New
Rent and the level of prevailing tenant improvements, they will look to the
leases signed within the prior six (6) months for space on the first floor of
the following buildings: 1800 9th Avenue, Marsh McLennon Building and the
Metropolitan Park Buildings. If there are no leases signed within that time
period for the first floor space in those buildings, then the parties will use
leases signed within the last six (6) months for space in the top 35% of floor
space in those buildings. The parities agree to select an independent appraiser
who will contact the owners of those buildings, obtain the most recent lease
rates for the applicable space, average the result (if there are more than one)
and produce the figure which shall be considered the "New Rent". The appraiser
shall also determine the average level of tenant improvements provided by
landlords for those comparable leases and that is the level of tenant
improvements to be provided by Lessor in the Expansion Space, at Lessor's
expense. The party who is furthest from the appraiser's New Rent shall pay the
fee of the appraiser, who's determination will be binding. Lessor shall prepare
and Lessee shall execute a lease amendment for the extension within thirty (30)
days after determination of the New Rent, who's determination will be binding.
Lessor shall prepare and Lessee shall execute a lease amendment for the
extension within thirty (30) days after Lessee's not)notification to Lessor of
its intent to expand. In addition, Lessee shall pay the reasonable costs to
relocate the existing tenant from the Expansion Space as may be provided in that
tenant's lease, to another location in the building, including the cost of
equivalent tenant improvements in the new space.

4.   PARKING. Lessee will be entitled to the use of one parking stall per 1,000
rentable square feet leased, for the term of the Lease, in the garage or on the
surrounding lots, at market rates. If the Premises expands to more than 4,720
rentable square feet. Lessee shall be entitled to one (1 additional parking
stall for each additional 1, 000 rentable square feet leased.

5.   OPTION TO CANCEL. Provided Lessee is not in default of any term or
condition of the Lease on the date of the notice described below or on the date
of Lease cancellation, Lessor shall provide Lessee with an Option to Cancel this
Lease at the commencement of the sixth, seventh and eighth years of the Lease
Term. Lessee shall provide not less than ten (10) months prior written notice of
its intent to cancel. Also, Lessee shall pay Lessor a Lease cancellation penalty
along with its notice to cancel. The cancellation penalty shall be equal to the
unamortized portion of the tenant improvements and the real estate commission
plus the following payment:

         Cancellation Timing                        Payment
         -------------------                        -------

In the event that Lessee leases the Expansion Space, Lessee shall occupy the
Expansion Space and the Initial Premises for a minimum of five (5) years from
the date of occupancy of the Expansion Space.

6.   ADDITIONAL SPACE. Following execution of this Lease by Lessee and Lessor,
Lessor shall notify Chiyoda of Lessor's intent to relocate Chiyoda from the
Premises pursuant to the provisions of the lease between Chiyoda and Lessor. In
this notice Lessor will notify Chiyoda of its intent to recapture an additional
portion of Chiyoda's Premises (approximately 105 rentable square feet) as
depicted in the Floor Plan attached as Exhibit A. Should Chiyoda consent to
Lessor's acquisition of this Additional Space, Lessor and Lessee shall
immediately amend this Lease to add such additional space to the Premises and
the leasing of this Additional Space by Lessee shall be under the same terms and
conditions of this Lease.

                          CHIYODA RELOCATION AMENDMENT

                            AMENDMENT TO LEASE NO. 3

This Amendment To Lease No. 3 dated this 29 day of March, 1995, is between
CHIYODA INTERNATIONAL CORPORATION, hereinafter after referred to as ("Lessee"),
and MARTIN SELIG, hereinafter referred to as ("Lessor"). On the 6th day of
February, 1991, Lessor and Lessee entered into a Lease covering premises (the
"Premises" herein) for Lessee's use in a building located at 1100 Olive Way,
Seattle, Washington 98101 (the "Building" herein), all as more particularly
described in the Lease. Lessor and Lessee desire to modify the Lease in certain
respects.

NOW, THEREFORE, AS PARTIES HERETO, Lessee and Lessor agree:

     1.   DESCRIPTION. Lessee shall continue to lease 19,960 rentable square
          feet on the 5th floor. In addition, Lessee will lease approximately
          5,000 rentable square feet (but shall be at least 5,000 rentable
          square feet calculated per BOMA Standards) elsewhere in the building.
          The exact size and location of the additional space will be mutually
          agreed upon by both Lessor and Lessee. In the meantime, Lessee shall
          continue to occupy its current 1st floor Premises of approximately
          6,510 rentable square feet. However, rent for the 1st floor space will
          be calculated as if Lessee were occupying 5,000 rentable square feet
          effective March 1, 1995.

     2.   TERM. Commencing March 1, 1995, the term of the Lease Amendment and
          the Master Lease as it applies to the 5th floor shall be extended to
          expire May 19th, 2001. The Term of the Lease Amendment and the Master
          Lease as it applies to the 1st floor Premises shall be extended to
          expire May 19th, 1999. However, if Lessee's 1st floor Premises are
          located elsewhere in the building, the Lease term for the relocated
          1st floor Premises shall be extended to expire May 19th, 2001.

     3.   RENT. The annual base rental rate shall be $14.25 per rentable square
          foot for the entire Premises effective March 1, 1995.

     4.   FIRST FLOOR PREMISES. At such time as Lessor has approximately 5,000
          contiguous rentable square feet of space available elsewhere in the
          building that provides Lessee with reasonably acceptable alternative
          space to the 1st floor Premises, Lessor may relocate Lessee from the
          1st floor. Lessor will provide Lessee with a minimum of three months
          advance written notice of Lessor's desire to relocate Lessee. The cost
          of such relocation, including any tenant improvements necessary to
          configure the space to Lessee's reasonable requirements, will be borne
          by Lessor.

     5.   FIRST FLOOR REMODEL. It is understood that Lessor has the right to
          remodel the 1st floor Premises. It is agreed that access to Lessee's
          1st floor Premises shall be provided by a hallway extending from the
          western entrance into the 1st floor Premises to the Premises Lessee
          occupies on the 1st floor. It is further understood that if Lessor has
          need of additional space on the 1st floor 


                                      165
<PAGE>   30

          and there is no other space available in the building to relocate
          Lessee's 1st floor Premises to, that Lessor shall have the right to
          remodel Lessee's 1st floor Premises into a configuration that is
          reasonably satisfactory to Lessee arid is at least 5,000 rentable
          square feet. Unless Lessee requests additional space, Lessee's rent
          shall be computed on no more than 5,000 rentable square feet. The
          reconfigured space will be located on two window walls and have a
          similar level and quantity of improvements as now exists in Lessee's
          1st floor space. Remodeling expenses and all architectural fees and
          costs shall be borne by Lessor. Lessor will use its best efforts to
          minimize the disruption to Lessee's day to day activities. The cost of
          this remodeling, including a temporary relocation of Lessee if
          necessary, together with all costs associated with that relocation
          will be performed at Lessor's sole cost and expense.

     6.   OPTION TO EXTEND. So long as Lessee is not in default under any of the
          terms and conditions of the Master Lease as amended, Lessee shall have
          the option to extend the Lease on the 1st floor Premises, assuming
          that it is still located on the 1st floor, for an additional two year
          period. Lessee shall also have the option to extend the Lease term on
          just the 5th floor Premises or the 5th and 1st floor Premises,
          wherever the 1st floor Premises may be located within the building,
          for an additional five year term expiring May 19th, 2006. Lessee
          agrees to provide Lessor with a minimum of six months advance written
          notice of their intent to exercise this option. The rental rate and
          other terms of the extension option shall be as specified in the
          Master Lease.

     7.   OPERATING EXPENSE ESCALATIONS. The base year for calculation of
          Lessee's share of the operating expense and real estate tax increases
          for the building shall be adjusted to be 1995 and will be based upon
          24,960 rentable square feet. All other terms and conditions of
          Paragraph 19 of the Lease, Operating Services and Real Estate Taxes,
          shall remain the same.

     8.   RIGHT OF FIRST REFUSAL. Lessee shall have the first right of refusal
          to lease either the 4th or the 6th floor subject to any existing
          encumbrances as of the execution date of this Lease Amendment. The
          rental rate for such right of first refusal space shall be based upon
          the fair market rent as further defined in Paragraph 38 of the Master
          Lease. Any right of first refusal space would have a term expiring
          coterminous with the 5th floor leased Premises.

     9.   PARKING. Lessor shall provide Lessee with up to thirty (30) parking
          stalls in the building's parking garage, ten (10) of which will be
          free of charge. The balance will be available at the prevailing market
          rates. In addition, an additional thirty (30) stalls shall be provided
          within a three block radius of the building at the prevailing market
          rate. At such time as Lessor leases the balance of the vacant space on
          the 1st floor of the building or relocates Lessee elsewhere in the
          building, Lessee's parking allocation shall be adjusted to reflect one
          (1) inside parking stall per 1,000 rentable square feet

Dear Ed:

Pursuant to Exhibit F, Section 3 of the office lease between Targeted Genetics
Corporation and Benaroya Capital Company, dated October 7, 1996, and further to
our MEETING of Wednesday, January 22, 1997, the following is agreed to by the
parties:

         Targeted Genetics Corporations lease in Metropolitan Park West Tower
         commenced on December 1, 1996. The first month of rent was January 1,
         1997. However the tenant improvements have not yet begun. The Lease
         provides for the Lessor to pay $70,800.00 toward tenant improvements.
         TENANT improvements in excess of the $70,800.00 are to be financed by
         LESSOR at 12%. The commencement date for the amortization period of the
         tenant improvements shall begin upon Lessor issuing a check following
         receipt of a draw request by Lessee. Hence, the term for amortizing the
         additional tenant improvements shall begin upon issuance of the check
         and shall expire upon the expiration date of the lease.

Please indicate your agreement to this clarification by signing below. We look
forward to the beginning of construction work which is scheduled to begin
sometime this summer.

Sincerely,

Dear Bob,

Regarding the square foot calculations in our lease with Benaroya for the Met
Park space there are two issues. The first is we need an amendment to the lease
to include the additional space we are taking. The second, is our square foot
determination is slightly different than Benaroya's and we need to have some
sort of reconciliation.

I have attached a SF take-off provided by ARC. ARC calculates the space to be
4,419 SF which includes an additional 89 SF to relocate the demising wall. With
the 6% load factor, this yields a total of 4,684 rentable SF. Our lease
estimates the space to be 4,720 RSF excluding the additional 89 SF.

One option would be to suggest the lease stands as is, but we modify Exhibit A
to show the new demising line. What do you think? Call me so we can discuss.

Regards,

/s/ Vickie Cleator

                              SECTION 4 ELIGIBILITY

      An incentive stock option may be granted only to an individual who, at the
time the option is granted, is an employee of the Company or a related

exercise of each option and the price per share at which such option is
exercisable (the "exercise price") shall be as established by the Plan
Administrator; provided, however, that the maximum number of shares with respect
to which an option or options may be granted to any Optionee in any one fiscal
year of the Company shall not exceed 200,000 shares (the "Maximum Annual
Optionee Grant"); provided further that the Plan Administrator shall act in good
faith to establish an exercise price which shall be not less than the fair
market value per share of the Common Stock at the time the option is granted
and, with respect to incentive stock options granted to greater than 10%
shareholders (as described in Section 6), the exercise price shall be as
required by subsection 6.1.

      5.2   TERM AND MATURITY

      Subject to the restrictions contained in Section 6 with respect to
granting incentive stock options to greater than 10% shareholders, the term of
each incentive stock option shall be as established by the Plan Administrator
and, if not so established, shall be ten years from the date it is granted but
in no event shall the term of any incentive stock option exceed ten years. The
term of each nonqualified stock option shall be as established by the Plan
Administrator, and if not so established, shall be ten years. To ensure that the
Company or related corporation will achieve the purpose and receive the benefits
contemplated by this Plan, any option granted to any Optionee shall, unless the
condition of this sentence is waived or modified in the agreement evidencing the
option or by resolution adopted by the Plan Administrator, be exercisable

</TABLE>

      5.3   EXERCISE

      Subject to the vesting schedule described in subsection 5.2 and to any
additional holding period required by applicable law, each option may be
exercised in whole or in part; provided, however, that no fewer than 20% of the
shares purchasable under the option (or the remaining shares then purchasable
under the option, if less than 20%) may be purchased upon any exercise of any
option and that only whole shares will be issued pursuant to the exercise of any
option. An option shall be exercised by delivery to the Company of notice of the
number of shares with respect to which the option is exercised, together with
payment of the exercise price.

      5.4   PAYMENT OF EXERCISE PRICE

      Payment of the option exercise price shall be made in full at the time the
notice of exercise of the option is delivered to the Company and shall be in
cash, bank certified or cashier's check, or personal check (unless at the time
of exercise the Plan Administrator in a particular case determines not to accept
a personal check) for the shares being purchased. The Plan Administrator may
determine at any time before exercise that additional forms of payment will be
permitted. To the extent permitted by applicable laws and regulations
(including, without limitation, federal tax and securities laws and state
corporate law), and unless the Plan Administrator determines otherwise, an
option may be exercised, either singly or in combination with one or more of the
alternative forms of payment authorized by this Section 5.4, by:

      (a) tendering (either actually or by attestation) shares of Common Stock
of the Company held by an Optionee having a fair market value equal to the
exercise price, such fair 


                                      173

<PAGE>   5

market value to be determined in good faith by the Plan Administrator; provided,
however, that payment in shares of Common Stock shall not be made unless the
shares of Common Stock shall have been owned by the Optionee for a period of at
least six months (or any shorter period necessary to avoid a charge to the
Company's earnings for financial accounting purposes); or

      (b) delivery of a properly executed exercise notice, together with
irrevocable instructions to a broker, all in accordance with the regulations of
the Federal Reserve Board, to promptly deliver to the Company the amount of sale
or loan proceeds to pay the exercise price and any federal, state or local
withholding tax obligations that may arise in connection with the exercise.

      In addition, the exercise price for shares purchased under an option may
be paid, either singly or in combination with one or more of the alternative
forms of payment authorized by this Section 5.4, by (y) delivery of a
full-recourse promissory note executed by the Optionee; provided, however, that
(i) such note delivered in connection with an incentive stock option shall, and
such note delivered in connection with a nonqualified stock option may, in the
sole discretion of the Plan Administrator, bear interest at a rate specified by
the Plan Administrator but in no case less than the rate required to avoid
imputation of interest (taking into account any exceptions to the imputed
interest rules) for federal income tax purposes, (ii) the Plan Administrator in
its sole discretion shall specify the term and other provisions of such note at
the time an incentive stock option is granted or at any time prior to exercise
of a nonqualified stock option, (iii) the Plan Administrator may require that
the Optionee pledge to the Company for the purpose of securing the payment of
such note the shares of Common Stock to be issued to the Optionee upon exercise
of the option and may require that the certificate representing such shares be
held in escrow in order to perfect the Company's security interest, and (iv) the
Plan Administrator in its sole discretion may at any time restrict or rescind
this right upon notification to the Optionee; or (z) such other consideration as
the Plan Administrator may permit.

5.5   WITHHOLDING TAX REQUIREMENT

      The Company or any related corporation shall have the right to retain and
withhold from any payment of cash or shares of Common Stock under this Plan the
amount of taxes required by any government to be withheld or otherwise deducted
and paid with respect to such payment. At its discretion, the Company may
require an Optionee receiving shares of Common Stock to reimburse the Company
for any such taxes required to be withheld by the Company and withhold any
distribution in whole or in part until the Company is so reimbursed. In lieu
thereof, the Company shall have the right to withhold from any other cash
amounts due or to become due from the Company to the Optionee an amount equal to
such taxes. The Company may also retain and withhold or the Optionee may elect,
subject to approval by the Company in its sole discretion, to have the Company
retain and withhold a number of shares having a market value not less than the
amount of such taxes required to 



                                      174

<PAGE>   6

be withheld by the Company to reimburse the Company for any such taxes and
cancel (in whole or in part) any such shares so withheld.

      5.6   HOLDING PERIODS

            5.6.1    SECURITIES EXCHANGE ACT SECTION 16

      If an individual subject to Section 16 of the Exchange Act sells shares of
Common Stock obtained upon the exercise of a stock option within six months
after the date the option was granted, such sale may result in short-swing
profit recovery under SectionU16(b) of the Exchange Act.

            5.6.2    TAXATION OF STOCK OPTIONS

      In order to obtain certain tax benefits accorded to incentive stock
options under Section 422 of the Code, an Optionee must hold the shares issued
upon the exercise of an incentive stock option for two years after the date of
grant of the option and one year from the date of exercise. An Optionee may be
subject to the alternative minimum tax at the time of exercise.

      The Plan Administrator may require an Optionee to give the Company prompt
notice of any disposition of shares acquired by the exercise of an incentive
stock option prior to the expiration of such holding periods.

      Tax advice should be obtained by an Optionee when exercising any option
and prior to the disposition of the shares issued upon the exercise of any
option.

5.7   TRANSFERABILITY OF OPTION

      No option granted under this Plan may be assigned, pledged or transferred
by the Optionee other than by will or by the laws of descent and distribution,
and during the Optionee's lifetime, such options may be exercised only by the
Optionee or a permitted assignee or transferee of the Optionee (as provided
below). Notwithstanding the foregoing, and to the extent permitted by Section
422 of the Code, the Plan Administrator, in its sole discretion, may permit such
assignment, transfer and exercisability and may permit an Optionee to designate
a beneficiary who may exercise the option after the Optionee's death; provided,
however, that any option so assigned or transferred shall be subject to all the
same terms and conditions contained in the instrument evidencing the option.

5.8   TERMINATION OF RELATIONSHIP

      If the Optionee's relationship with the Company or any related corporation
ceases for any reason other than termination for cause, death or total
disability, and unless by its terms the option sooner terminates or expires,
then the portion of the option which is not exercisable at the time of such
cessation shall terminate immediately upon such cessation, 



                                      175

<PAGE>   7

unless the Plan Administrator determines otherwise, and the portion of the
option which is exercisable at the time of such cessation, (i) may be exercised
for a three-month period after such cessation and (ii) unless the Plan
Administrator determines otherwise, shall terminate at the end of such period
following such cessation as to all shares for which it has not theretofore been
exercised. If, in the case of an incentive stock option, an Optionee's
relationship with the Company or related corporation changes (i.e., from
employee to nonemployee, such as a consultant), such change shall constitute a
termination of an Optionee's employment with the Company or related corporation
and the Optionee's incentive stock option shall terminate in accordance with
this subsection. Upon the expiration of the three-month period following
cessation of employment in the case of an incentive stock option, or at any time
prior to the expiration of the option in the case of a nonqualified stock
option, the Plan Administrator shall have sole discretion in a particular
circumstance to extend the exercise period following such cessation beyond that
specified above. If, however, in the case of an incentive stock option, the
Optionee does not exercise the Optionee's option within three months after
cessation of employment, the option will no longer qualify as an incentive stock
option under the Code.

      If an Optionee is terminated for cause, each option shall automatically
terminate as of the first discovery by the Company of any reason for termination
for cause, and such Optionee shall thereupon have no right to purchase any
shares pursuant to such option. "Termination for cause" shall mean dismissal for
dishonesty, conviction or confession of a crime (except minor violations),
fraud, misconduct or disclosure of confidential information.

      If an Optionee's relationship with the Company or any related corporation
is suspended pending an investigation of whether or not the Optionee shall be
terminated for cause, the Optionee's rights under each option likewise shall be
suspended during the period of investigation.

      If an Optionee's relationship with the Company or any related corporation
ceases because of a total disability, the portion of Optionee's option which is
exercisable at the time of such cessation shall not terminate or, in the case of
an incentive stock option, cease to be treated as an incentive stock option
until the end of the twelve month period following such cessation (unless by its
terms it sooner terminates or expires). As used in this Plan, the term "total
disability" refers to a mental or physical impairment of the Optionee which is
expected to result in death or which has lasted or is expected to last for a
continuous period of twelve months or more and which causes the Optionee to be
unable, in the opinion of the Company and two independent physicians, to perform
his or her duties for the Company. Total disability shall be deemed to have
occurred on the first day after the Company and the two independent physicians
have furnished their opinion of total disability to the Plan Administrator.

      For purposes of this subsection 5.8, a transfer between or among the
Company and any related corporation shall not be deemed to constitute a
cessation of the Optionee's relationship with the Company or any related
corporation. For purposes of this subsection 5.8, with respect to incentive
stock options, employment shall be deemed to 



                                      176

<PAGE>   8

continue while the Optionee is on military leave, sick leave or other bona fide
leave of absence (as determined by the Plan Administrator). The foregoing
notwithstanding, employment shall not be deemed to continue beyond the first 90
days of such leave, unless the Optionee's reemployment rights are guaranteed by
statute or by contract.

      As used herein, the term "related corporation," when referring to a
subsidiary corporation, shall mean any corporation (other than the Company) in
an unbroken chain of corporations beginning with the Company if, at the time of
the granting of the option, stock possessing 50% or more of the total combined
voting power of all classes of stock of each of the corporations other than the
Company is owned by one of the other corporations in such chain. When referring
to a parent corporation, the term "related corporation" shall mean any
corporation in an unbroken chain of corporations ending with the Company if, at
the time of the granting of the option, each of the corporations other than the
Company owns stock possessing 50% or more of the total combined voting power of
all classes of stock in one of the other corporations in such chain.

5.9   DEATH OF OPTIONEE

      If an Optionee dies while he or she has a relationship with the Company or
any related corporation or within the three-month period (or twelve month period
in the case of totally disabled Optionees) following cessation of such
relationship, any option held by such Optionee to the extent that the Optionee
would have been entitled to exercise such option, may be exercised within one
year after his or her death by the person, if any, designated by the Optionee
pursuant to subsection 5.7 to exercise the option after the Optionee's death, by
the personal representative of his or her estate or by the person or persons to
whom the Optionee's rights under the option shall pass (a) by will or by the
applicable laws of descent and distribution or (b) by a designation or transfer
pursuant to Section 5.7.

5.10  NO STATUS OF SHAREHOLDERS

      Neither the Optionee nor any party to which the Optionee's rights and
privileges under the option may pass shall be, or have any of the rights or
privileges of, a shareholder of the Company with respect to any of the shares
issuable upon the exercise of any option granted under this Plan unless and
until such option has been exercised.

5.11  CONTINUATION OF EMPLOYMENT

      Nothing in this Plan or in any option shall confer upon any Optionee any
right to continue in the employ of the Company or of a related corporation, or
to interfere in any way with the right of the Company or of any such related
corporation to terminate his or her employment or other relationship with the
Company at any time.

5.12  MODIFICATION AND AMENDMENT OF OPTION



                                      177

<PAGE>   9

      Subject to the requirements of Code Section 422 with respect to incentive
stock options and to the terms and conditions of this Plan, the Plan
Administrator may modify or amend any outstanding options. The modification or
amendment of an outstanding option shall not, without the consent of the
Optionee, impair or diminish any of his or her rights or any of the obligations
of the Company under such option. Except as otherwise provided in this Plan, no
outstanding option shall be terminated without the consent of the Optionee.
Unless the Optionee agrees otherwise, any changes or adjustments made to
outstanding incentive stock options shall be made in such a manner so as not to
constitute a "modification" as defined in Code Section 424(h) and so as not to
cause any incentive stock option to fail to continue to qualify as an incentive
stock option as defined in Code Section 422(b).

5.13  LIMITATION ON VALUE FOR INCENTIVE STOCK OPTIONS

      As to all incentive stock options granted under the terms of this Plan, to
the extent that the aggregate fair market value of the shares (determined at the
time the incentive stock option is granted) with respect to which incentive
stock options are exercisable for the first time by the Optionee during any
calendar year (under this Plan and all other incentive stock option plans of the
Company, a related corporation or a predecessor corporation) exceeds $100,000,
such options shall be treated as nonqualified stock options, to the extent
required by Section 422 of the Code.

                 SECTION 6 GREATER THAN 10% SHAREHOLDERS

6.1   EXERCISE PRICE AND TERM OF INCENTIVE STOCK OPTIONS

      If an incentive stock option is granted under this Plan to any employee
who owns more than 10% of the total combined voting power of all classes of
stock of the Company or any related corporation, the term of such incentive
stock options shall not exceed five years and the exercise price shall be not
less than 110% of the fair market value of the shares at the time the incentive
stock option is granted. This provision shall control notwithstanding any
contrary terms contained in an option agreement or any other document.

6.2   ATTRIBUTION RULE

      For purposes of subsection 6.1, in determining stock ownership, an
employee shall be deemed to own the shares owned, directly or indirectly, by or
for his or her brothers, sisters, spouse, ancestors and lineal descendants.
Shares owned, directly or indirectly, by or for a corporation, partnership,
estate or trust shall be deemed to be owned proportionately by or for its
shareholders, partners or beneficiaries. If an employee or a person related to
the employee owns an unexercised option or warrant to purchase shares of the
Company, the shares subject to that portion of the option or warrant which is
unexercised shall not be counted in determining stock ownership. For purposes of
this Section 6, shares owned by an employee shall include all shares actually
issued and outstanding immediately before the grant of the incentive stock
option to the employee.



                                      178

SECTION 7.  ADJUSTMENTS

      7.1   ADJUSTMENT OF SHARES

      In the event that, at any time or from time to time, a stock dividend,
stock split, spin-off, combination or exchange of shares, recapitalization,
merger, consolidation, distribution to shareholders other than a cash dividend,
or other change in the Company's corporate or capital structure results in (a)
the outstanding shares, or any securities exchanged therefor or received in
their place, being exchanged for a different number or class of securities of
the Company or of any other corporation or (b) new, different or additional
securities of the Company or of any other corporation being received by the
holders of shares of Common Stock of the Company, then the Plan Administrator
shall make proportional adjustments in (i) the maximum number and class of
securities subject to this Plan as set forth in Section 3, (ii) the maximum
number and class of securities that may be made subject to options granted to
any individual participant as set forth in Section 5.1, and (iii) the number and
class of securities that are subject to any outstanding option and the per share
price of such securities, without any change in the aggregate price to be paid
therefor. The determination by the Plan Administrator as to the terms of any of
the foregoing adjustments shall be conclusive and binding.

7.2   CHANGE IN CONTROL

      Except as otherwise provided in the instrument that evidences the option,
in the event of any Change in Control, each option that is at the time
outstanding shall automatically accelerate so that each such option shall,
immediately prior to the specified effective date for the Change in Control,
become 100% vested, except that such acceleration will not occur, if in the
opinion of the Company's accountants, it would render unavailable "pooling of
interest" accounting for a Change in Control that would otherwise qualify for
such accounting treatment. Such option shall not so accelerate, however, if and
to the extent that (a) such option is, in connection with the Change in Control,
either to be assumed by the successor corporation or parent thereof (the
"Successor Corporation") or to be replaced with a comparable award for the
purchase of shares of the capital stock of the Successor Corporation or (b) such
option is to be replaced with a cash incentive program of the Successor
Corporation that preserves the spread existing at the time of the Change in
Control and provides for subsequent payout in accordance with the same vesting
schedule applicable to such option. The determination of comparability under
clause (a) above shall be made by the Plan Administrator, and its determination
shall be conclusive and binding. All such options shall terminate and cease to
remain outstanding immediately following the consummation of the Change in
Control, except to the extent assumed by the Successor Corporation. Any such
options that are assumed or replaced in the Change in Control and do not
otherwise accelerate at that time shall be accelerated in the event the
Optionee's employment or services should subsequently terminate within two years
following such Change in Control, unless such employment or services are
terminated by the Successor Corporation for Cause or by the Optionee voluntarily
without Good Reason.



                                      179

<PAGE>   11

7.3   FURTHER ADJUSTMENT OF OPTIONS

      Subject to the preceding Section 7.2, the Plan Administrator shall have
the discretion, exercisable at any time before a sale, merger, consolidation,
reorganization, liquidation or Change in Control of the Company to take such
further action as it determines to be necessary or advisable, and fair and
equitable to participants, with respect to options. Such authorized action may
include (but shall not be limited to) establishing, amending or waiving the
type, terms, conditions or duration of, or restrictions on, options so as to
provide for earlier, later, extended or additional time for exercise, lifting
restrictions and other modifications, and the Plan Administrator may take such
actions with respect to all participants, to certain categories of participants
or only to individual participants. The Plan Administrator may take such actions
before or after granting options to which the action relates and before or after
any public announcement with respect to such sale, merger, consolidation,
reorganization, liquidation or change in control that is the reason for such
action.

7.4   LIMITATIONS

      The grant of options will in no way affect the Company's right to adjust,
reclassify, reorganize or otherwise change its capital or business structure or
to merge, consolidate, dissolve, liquidate or sell or transfer all or any part
of its business or assets.

7.5   DEFINITIONS

            title, position, duties, responsibilities and status with the
            Company or any related corporation that employs the Optionee as
            such duties and responsibilities existed immediately prior to the
            date of the Change in Control, or (ii) removal of the Optionee
            from, or failure to re-elect the Optionee to, the Optionee's
            positions with the Company or any related corporation that

            except in connection with the involuntary termination of the
            Optionee's employment by the Company for Cause or as a result of
            the Optionee's death or disability, as defined by the Plan
            Administrator; or

<PAGE>   14

            residence than such principal place of employment immediately prior
            to the Change in Control; or

      (d)   the breach by the Company of any material provision of any

                         SECTION 8 SECURITIES REGULATION

      Shares of Common Stock shall not be issued with respect to any option
unless the exercise of such option and the issuance and delivery of such shares
pursuant thereto shall comply with all relevant provisions of law, including,
without limitation, any applicable state securities laws, the Securities Act of
1933, as amended, the Exchange Act, the rules and regulations promulgated
thereunder, and the requirements of any stock exchange upon which the shares may
then be listed, and shall be further subject to the approval of counsel for the
Company with respect to such compliance, including the availability, if
applicable, of an exemption from registration for the issuance and sale of any
shares hereunder.

                       SECTION 9 AMENDMENT AND TERMINATION

9.1   BOARD ACTION

      The Board may at any time suspend, amend or terminate this Plan, provided
that to the extent required for compliance with Section 422 of the Code or any
applicable law or regulation, the shareholders must approve any amendment that
will:

      (a)   increase the total number of shares which are to be reserved for
issuance in connection with options under this Plan;

      (b)   modify the class of participants eligible for participation in
this Plan; or

      (c)   otherwise require shareholder approval under any applicable law
or regulation.

      Such shareholder approval must be obtained within twelve months after the
adoption by the Board of such amendment.

      Any amendment made to this Plan which would constitute a "modification" to
incentive stock options outstanding on the date of such amendment, shall not be
applicable to such outstanding incentive stock options, but shall have
prospective effect only, unless the Optionee agrees otherwise.

      9.2   AUTOMATIC TERMINATION

      Unless sooner terminated by the Board, this Plan shall terminate ten years
from the earlier of (a) the date on which this Plan is adopted by the Board or
(b) the date on which this Plan is approved by the shareholders of the Company.
No option may be granted after such 



                                      183

<PAGE>   15

termination or during any suspension of this Plan. The amendment or termination
of this Plan shall not, without the consent of the Optionee, impair or diminish
any rights or obligations under any option theretofore granted under this Plan.

                      SECTION 10 EFFECTIVENESS OF THIS PLAN

      This Plan shall become effective upon adoption by the Board so long as it

                          TARGETED GENETICS CORPORATION
                  STOCK OPTION PLAN FOR NONEMPLOYEE DIRECTORS
                   AMENDED AND RESTATED ON OCTOBER 17, 1996

                               SECTION 1 PURPOSES

      The purpose of the Targeted Genetics Corporation Stock Option Plan for
Nonemployee Directors (this "Plan") is to attract and retain the services of
experienced and knowledgeable nonemployee directors for Targeted Genetics
Corporation (the "Company") and to provide added incentive to such directors by
providing an opportunity for stock ownership in the Company.

                            SECTION 2 ADMINISTRATION

      The administrator of this Plan (the "Plan Administrator") shall be the
Board of Directors of the Company (the "Board"). Subject to the terms of this
Plan, the Plan Administrator shall have the power to construe the provisions of
this Plan, to determine all questions arising hereunder and to adopt and amend
such rules and regulations for the administration of this Plan as it may deem
desirable.

                      SECTION 3 SHARES SUBJECT TO THE PLAN

      Subject to adjustment in accordance with Section 6 hereof, the total
number of shares of the Company's common stock (the "Common Stock") for which
options may be granted under this Plan is 120,000 (the "Shares"). The Shares
shall be shares currently authorized but unissued or subsequently acquired by
the Company and shall include shares representing the unexercised portion of any
option granted under this Plan which expires or terminates without being
exercised in full.

                              SECTION 4 ELIGIBILITY

4.1   ELIGIBLE DIRECTORS

      Each member of the Board elected or appointed who is not otherwise an
employee of the Company or any parent or subsidiary corporation (an "Eligible
Director") shall be eligible to participate in this Plan.

4.2   INITIAL GRANTS

      Immediately following his or her initial election or appointment to the
Board, each Eligible Director shall automatically receive an option to purchase
15,000 Shares.

4.3   ANNUAL GRANTS

                                      185

<PAGE>   2
      Each Eligible Director continuing service as an Eligible Director
immediately following an Annual Meeting of Shareholders shall automatically
receive an option to purchase 5,000 Shares immediately following each year's
Annual Meeting of Shareholders as an annual grant; provided that an Eligible
Director who has received an initial grant of 15,000 Shares on such date shall
not receive an annual grant until the next Annual Meeting.

4.4   AVAILABILITY OF SHARES

      No grant shall be made under this Plan if the effect of such grant would
be to obligate the Company to issue more Shares than are reserved under Section
3. If insufficient Shares are reserved under Section 3 to fully fund one or more
grants to be made under this Section 4 on the same date of grant, then the
Shares available shall be divided by the number of Eligible Directors then
entitled to a grant and each such Eligible Director shall be granted an option
for that number of Shares.

                             SECTION 5 OPTION TERMS

      Each option granted to an Eligible Director under this Plan and the
issuance of Shares hereunder shall be subject to the following terms:

5.1   OPTION AGREEMENT

      Each option shall be evidenced by an option agreement (an "Agreement")
duly executed on behalf of the Company. Each Agreement shall comply with and be
subject to the terms and conditions of this Plan. Any Agreement may contain such
other terms, provisions and conditions not inconsistent with this Plan as may be
determined by the Plan Administrator.

5.2   OPTION EXERCISE PRICE

      The option exercise price for an option shall be the closing price, or if
there is no closing price, the mean between the high and the low sale price of
shares of Common Stock on the Nasdaq Stock Market on the day the option is
granted or, if no Common Stock was traded on such date, on the next succeeding
day on which Common Stock is so traded.

5.3   VESTING AND EXERCISABILITY

      Each option granted to an Eligible Director shall vest and become
exercisable in accordance with the following schedule:

            Thirty-six months                                             100%
</TABLE>

5.4   TIME AND MANNER OF EXERCISE OF OPTION

      Each option may be exercised in whole or in part at any time and from time
to time; provided, however, that no fewer than 20% of the Shares purchasable
under the option (or the remaining Shares then purchasable under the option, if
less than 20%) may be purchased upon any exercise of any option hereunder and
that only whole Shares will be issued pursuant to the exercise of any option.

      Any option may be exercised by giving written notice, signed by the person
exercising the option, to the Company stating the number of Shares with respect
to which the option is being exercised, accompanied by payment in full for such
Shares, which payment may be in whole or in part (a) in cash or by check, (b) in
shares of Common Stock already owned for at least six months by the person
exercising the option, valued at fair market value at the time of such exercise,
or (c) by delivery of a properly executed exercise notice, together with
irrevocable instructions to a broker, to properly deliver to the Company the
amount of sale or loan proceeds to pay the exercise price, all in accordance
with the regulations of the Federal Reserve Board.

5.5   TERM OF OPTIONS

      Each option shall expire ten years from the date of the granting thereof,
but shall be subject to earlier termination as follows:

      (a) In the event that an Optionee ceases to be a director of the Company
for any reason other than the death of the Optionee, the unvested portion of the
options granted to such Optionee shall terminate immediately and the vested
portion of the options granted to such Optionee may be exercised by him or her
only within three months after the date such Optionee ceases to be a director of
the Company.



                                      187

<PAGE>   4

      (b) In the event of the death of an Optionee, whether during the
Optionee's service as a director or during the three-month period referred to in
Section 5.5(a), the unvested portion of the options granted to such Optionee
shall terminate immediately and the vested portion of the options granted to
such Optionee shall be exercisable, and such options shall expire unless
exercised within twelve months after the date of the Optionee's death, by the
legal representatives or the estate of such Optionee, by any person or persons
whom the Optionee shall have designated in writing on forms prescribed by and
filed with the Company or, if no such designation has been made, by the person
or persons to whom the Optionee's rights have passed by will or the laws of
descent and distribution.

5.6   TRANSFERABILITY

      During an Optionee's lifetime, an option may be exercised only by the
Optionee. Options granted under this Plan and the rights and privileges
conferred thereby shall not be subject to execution, attachment or similar
process and may not be transferred, assigned, pledged or hypothecated in any
manner (whether by operation of law or otherwise) other than by (a) will or by
the applicable laws of descent and distribution, or (b) by gift or other
transfer to either (i) a spouse or other immediate family member or (ii) any
trust or estate in which the Optionee or such Optionee's spouse or other
immediate family member has a substantial beneficial interest. In addition, an
Optionee may designate in writing during the Optionee's lifetime a beneficiary
to receive and exercise options in the event of the Optionee's death (as
provided in Section 5.5(b)). Any attempt to transfer, assign, pledge,
hypothecate or otherwise dispose of any option under this Plan or of any right
or privilege conferred thereby, contrary to the provisions of this Plan, or the
sale or levy or any attachment or similar process upon the rights and privileges
conferred hereby, shall be null and void.

5.7   HOLDING PERIOD

      If an individual subject to Section 16 of the Securities Exchange Act of
1934, as amended (the "Exchange Act") sells shares of Common Stock obtained upon
the exercise of any option granted under this Plan within six (6) months after
the date the option was granted, such sale may result in short-swing profit
recovery under Section 16(b) of the Exchange Act.

5.8   PARTICIPANT'S OR SUCCESSOR'S RIGHTS AS SHAREHOLDER

      Neither an Optionee nor the Optionee's successor in interest shall have
any rights as a shareholder of the Company with respect to any Shares subject to
an option granted to the Optionee until such person becomes a holder of record
of such Shares.

5.9   LIMITATION AS TO DIRECTORSHIP

      Neither this Plan, nor the granting of an option, nor any other action
taken pursuant to this Plan shall constitute or be evidence of any agreement or
understanding, express or implied, 



                                      188

<PAGE>   5

that an Optionee has a right to continue as a director for any period of time or
at any particular rate of compensation.

5.10  REGULATORY APPROVAL AND COMPLIANCE

      The Company shall not be required to issue any certificate or certificates
for Shares upon the exercise of an option granted under this Plan, or record as
a holder of record of Shares the name of the individual exercising an option
under this Plan, without obtaining to the complete satisfaction of the Plan
Administrator the approval of all regulatory bodies deemed necessary by the Plan
Administrator, and without complying, to the Plan Administrator's complete
satisfaction, with all rules and regulations under federal, state or local law
deemed applicable by the Plan Administrator.

                          SECTION 6 CAPITAL ADJUSTMENTS

6.1   RECAPITALIZATION

      The aggregate number and class of shares for which options may be granted
under this Plan, the number and class of shares covered by each outstanding
option and the exercise price per share thereof (but not the total price), shall
all be proportionately adjusted for any increase or decrease in the number of
issued shares of Common Stock of the Company resulting from a split or
consolidation of shares or any like capital adjustment, or the payment of any
stock dividend.

6.2   EFFECT OF LIQUIDATION OR REORGANIZATION

      Upon a merger (other than a merger of the Company in which the holders of
shares of Common Stock immediately prior to the merger have the same
proportionate ownership of shares of Common Stock in the surviving corporation
immediately after the merger), consolidation, acquisition of property or stock,
separation, reorganization (other than a mere reincorporation or the creation of
a holding company) or liquidation of the Company (each a "corporate
transaction"), as a result of which the shareholders of the Company receive
cash, stock or other property in exchange for or in connection with their shares
of Common Stock, then the Optionee shall have the right immediately prior to any
such merger, consolidation, acquisition of property or stock, reorganization or
liquidation to exercise such option in whole or in part whether or not the
vesting requirements set forth in the option agreement have been satisfied. To
the extent such option is not exercised, it shall terminate, except that in the
event of a corporate transaction in which the shareholders of the Company
receive capital stock of another corporation in exchange for their shares of
Common Stock, such unexercised option shall be assumed or an equivalent option
shall be substituted by the successor corporation or a parent or subsidiary of
such successor corporation. Any such assumed or equivalent option shall be 100%
vested and exercisable with respect to the total number of shares purchasable
under such option; provided that such acceleration will not occur if, in the
opinion of the Company's outside accountants, such acceleration would render
unavailable "pooling of interests" accounting treatment for such transaction for
which pooling of interests accounting treatment is sought by 



                                      189

<PAGE>   6

the Company. Upon a merger of the Company in which the holders of Common Stock
immediately prior to the merger have the same proportionate ownership of Common
Stock in the surviving corporation immediately after the merger, a mere
reincorporation or the creation of a holding company, each option outstanding
under the Plan shall be assumed or an equivalent option shall be substituted by
the successor corporation or a parent or subsidiary of such corporation, and the
vesting schedule set forth in the option agreement shall continue to apply to
such assumed or equivalent option.

6.3   FRACTIONAL SHARES

      In the event of any adjustment in the number of shares covered by any
option, any fractional shares resulting from such adjustment shall be
disregarded and each such option shall cover only the number of full shares
resulting from such adjustment.

                               SECTION 7 EXPENSES

      All costs and expenses of the adoption and administration of this Plan
shall be borne by the Company; none of such expenses shall be charged to any
Optionee.

                      SECTION 8 COMPLIANCE WITH RULE 16B-3

      It is the intention of the Company that this Plan comply in all respects
with the requirements for a "formula plan" within the meaning attributed to that
term for purposes of Rule 16b-3 promulgated under Section 16(b) of the Exchange
Act. Therefore, if any Plan provision is later found not to be in compliance
with such requirements, that provision shall be deemed null and void, and in all
events this Plan shall be construed in favor of its meeting such requirements.

                       SECTION 9 TERMINATION AND AMENDMENT

      The Board may amend, terminate or suspend this Plan at any time, in its
sole and absolute discretion; provided, however, that if required to qualify
this Plan as a formula plan for purposes of Rule 16b-3 under Section 16(b) of
the Exchange Act, no amendment may be made more than once every six months that
would change the amount, price, timing or vesting of the options, other than to
comply with changes in the Internal Revenue Code of 1986, as amended, or the
rules and regulations thereunder; provided further that no amendment that would
(a) increase the number of Shares that may be issued under this Plan, or (b)
otherwise require shareholder approval under any applicable law or regulation
shall be made without the approval of the Company's shareholders.

                               SECTION 10 DURATION



                                      190

<PAGE>   7

      This Plan shall continue in effect until March 2, 2004 unless it is sooner
terminated by action of the Board or the Company's shareholders, but such
termination shall not affect the then-outstanding terms of any options.

      Adopted by the Company's Board of Directors on March 2, 1994 and approved
by the Company's shareholders on March 23, 1994. Amended and restated by the
Board on October 17, 1996.
