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 has focused its
efforts on 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.
 
  The Company's three product development programs are summarized in the
following table.

  In addition to the product development programs summarized above, the
Company is performing research, both internally and through outside
collaborators, 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 HIV infection, melanoma and leukemia.
 
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 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 enrolling a total of 18 patients, two at each of nine
escalating dose levels. The tgAAV-CFTR is administered in an open-label single
dose to the right lower lobe of the lung via bronchoscopy and to one nostril.
Patients are monitored for, among other things, safety and assessment of gene
transfer and expression. A total of 19 patients have been treated in this
clinical trial with no apparent side effects related to the study drug.
 
  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, was completed in 1996. A total of ten patients were enrolled, and 15
sinuses were treated, in five cohorts receiving escalating doses. The results
of the trial suggests 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 the only patient measured at such timepoint, 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
are to receive tgAAV-CFTR in one sinus and a placebo in the other. Patients in
the Phase II trial are 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 and the Company expects to complete patient treatment in the
first half of 1998.
 
  The Company is preparing to initiate a Phase I clinical trial in 1998
involving the aerosol delivery of tgAAV-CFTR to the whole lung. The Company
expects to begin a toxicology study in non-human primates in the first half of
1998, which must be completed prior to beginning the clinical trial.

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 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.
 
  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 and his colleagues 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. In
preclinical mouse studies, E1A was shown to inhibit expression of the HER-
2/neu oncogene, to inhibit growth and metastasis of cancer cells, and to
increase significantly the long-term survival of the mice. The Company has
worldwide rights to the use of the E1A gene as a tumor suppressor under
patents filed by Dr. Hung.
 
  Other research, conducted by Dr. Steven Frisch and his colleagues at the
Burnham Institute, has suggested that E1A may have other tumor suppression
activity unrelated to the inhibition of HER-2/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
was also shown in preclinical studies to sensitize tumor cells to killing by
certain chemotherapeutic agents. The Company has worldwide rights to patents
filed by Dr. Frisch that are complementary to those filed by Dr. Hung.
 
  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, 18 patients with ovarian or breast cancer received weekly doses of
tgDCC-E1A for up to six months. In early 1997, two additional sites were added
to the study, Rush Presbyterian Medical Center in Chicago ("Rush") and
Virginia Mason Medical Center in Seattle. This trial was 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 were to assess safety,
levels of gene transfer and expression and tumor response. Data from the study
are currently being analyzed.
 
  A second Phase I clinical trial began in early 1997 at M.D. Anderson, Rush,
and Wayne State University in Detroit, in which 18 patients with inoperable
primary head or neck tumors or metastatic breast or lung tumors were
administered up to ten weekly doses of tgDCC-E1A, injected directly into the
patient tumor. The trial was conducted as an interpatient escalating dose
study with up to six patients in each of four dose cohorts. The objectives of
the trial were to assess safety, levels of gene transfer and expression and
tumor response. A total of 18 patients were treated in the trial, which was
completed in December 1997. Data from the study are currently being analyzed.
 
  Based on the data obtained from the two Phase I clinical trials described
above, the Company has begun planning a Phase II clinical trial of tgDCC-E1A
in head and neck cancer. This trial is expected to begin in the second half of
1998.
 
  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
 
                                       5
<PAGE>
 
in Europe. Fournier is conducting a Phase I clinical trial in ovarian cancer
patients at five hospitals in the United Kingdom and plans to begin additional
clinical trials in 1998. See "Research and Development Collaborations."
 
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 six HIV-
infected patients were administered five escalating doses of Targeted CTLs
specific to the HIV gag protein. The first three doses consisted of unmarked
cells and the last two consisted of cells modified with a retroviral vector
containing a marker gene. Patients in the trial are monitored for safety,
persistence of the infused Targeted CTLs and changes in viral burden. The
results of the trial are expected to be published in 1998. The Company and its
collaborators at the Hutchinson Center are evaluating options related to
additional trials in HIV.
 
  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 took the necessary steps to adapt its Targeted CTL
technology to the treatment of HBV in preparation for a preclinical study in
which chimpanzees chronically infected with HBV are to be administered
Targeted CTLs. The objective of the study, which began 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
 
                                       6
<PAGE>
 
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
transferred 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.
 
  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
 
                                       7
<PAGE>
 
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 internal
efforts in this area to cells of the cardiovascular system and the
gastrointestinal tract. The Company plans to examine the use of its 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 is working to develop a series of these non-viral delivery
systems based on discoveries 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 or co-exclusive license to an
issued U.S. patent for the original DC Chol system for the treatment of cancer
and certain other diseases. 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
an even 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. The Company's initial internal efforts in this area,
based on the work of Dr. Huang, are devoted to the development of an efficient
lipid-based delivery vehicle with properties suitable for systemic delivery of
genes to target tissues via the bloodstream.
 
  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 an improved retroviral vector
packaging cell line called PG13, which the Company has licensed
 
                                       8
<PAGE>
 
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.
 
 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 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. Dr. Riddell is now
conducting a Phase II clinical trial following up on the promising results
observed in Phase I.
 
 
                                       9
<PAGE>
 
  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, HBV,
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 $2.5 million of
milestone payments through the end of 1997. 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. The
Company has a supply agreement under which it sells DC Chol to Pasteur
Merieux. 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
 
                                      10
<PAGE>
 
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 56 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, 17
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 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
 
                                      11
<PAGE>
 
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, 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.
 
                                      12
<PAGE>
 
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 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
 
                                      13
<PAGE>
 
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, 1997, Targeted Genetics had 90 full time equivalent
employees; effective February 15, 1998, the Company reduced its workforce to
64 full time equivalent employees in order to reduce the amount of cash being
used to fund operations. Of the remaining employees, 50 are directly involved
in research and development, of whom 9 have Ph.D. or M.D. degrees. A
significant number of the Company's management and professional employees have
prior experience with other biotechnology or pharmaceutical companies. The
Company considers its relations with its remaining 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. After the recent workforce reduction, the
Company put into place several programs involving restructuring and repricing
of stock options and cash retention bonuses in order to provide
 
                                      14
<PAGE>
 
appropriate incentive to all retained employees to continue their employment
with the Company. However, 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
qualified.

</TABLE>
 
  H. Stewart Parker managed the formation of Targeted Genetics as a wholly
owned subsidiary of Immunex and has been President, Chief Executive Officer
and a director since the Company's inception in 1989. She served in various
capacities at Immunex from August 1981 through December 1991, most recently as
Vice President, Corporate Development. Ms. Parker also served as President and
a director of Receptech Corporation, a company formed by Immunex in 1989 to
accelerate the development of soluble cytokine receptor products
("Receptech"), from February 1991 to January 1993. She received her B.A. and
M.B.A. from the University of Washington.
 
  Barrie J. Carter is Executive Vice President and Director of Research and
Development of Targeted Genetics. He joined the Company in August 1992. For
the previous 22 years he was employed by the NIH in Bethesda, Maryland where
he was Chief of the Laboratory of Molecular and Cellular Biology in the
National Institute for Diabetes and Digestive and Kidney Diseases from 1982 to
1992. Dr. Carter received his B.Sc. (Honors) from the University of Otago,
Dunedin, New Zealand and his Ph.D. in the Biochemistry Department of the
University of Otago Medical School. He then spent a period of postdoctoral
training at the Imperial Cancer Research Fund Laboratories in London, England
before joining the NIH. His long-term research interests are in molecular
biology of viruses, development of AAV vectors and gene therapy. Dr. Carter
serves on the Editorial Boards of Human Gene Therapy and Molecular
Therapeutics: Gene Therapy & Oligonucleotides and as an Associate Editor of
Virology. Since 1995, he has been an Affiliate Professor of Medicine at the
University of Washington Medical School.
 
  James A. Johnson joined the Company in March 1994 as Vice President,
Finance, Chief Financial Officer, Treasurer and Secretary. He was employed by
Immunex from January 1988 to February 1994, initially as Director of Finance
and as Vice President, Finance since February 1990. While at Immunex, Mr.
Johnson served as Treasurer of Targeted Genetics from its inception in 1989.
From November 1989 to January 1993, he also served as Treasurer and Assistant
Secretary of Receptech. He received his B.A. from the University of
Washington.
 
FACTORS AFFECTING FORWARD-LOOKING INFORMATION
 
  Need for Additional Capital. The Company expects negative cash flow from
operations to continue in 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
 
                                      15
<PAGE>
 
programs. Furthermore, if at any time the Company's funds are depleted, the
Company may be required to cease operations. The Company estimates that its
cash, cash equivalents and securities available for sale will be sufficient to
meet its needs until May 1998.
 
  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.
 
  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 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."
 
 
                                      16
<PAGE>
 
  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.
 
  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
 
                                      17
<PAGE>
 
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 3. LEGAL PROCEEDINGS
 
  The Company is not a party to any legal proceedings.
 
ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

  On March 15, 1997, the Company issued to The Burnham Institute a warrant to
purchase up to 50,000 shares of the Company's common stock (the "Burnham
Warrant") as partial consideration for the execution of a license agreement.
The Burnham Warrant vested 16,667 shares upon execution of such license
agreement; additional shares vest upon the occurrence of certain milestones
relating to pre-clinical animal studies and the issuance of patents. The
vested portion of the Burnham Warrant is exercisable until March 15, 2004 at
an exercise price per share of $4.50. On May 15, 1997, the Company issued to
Francis Chisari a warrant to purchase up to 25,000 shares of the Company's
common stock (the "Chisari Warrant") as partial consideration for the
execution of a consulting agreement. The Chisari Warrant vested 5,000 shares
immediately; on each May 15, beginning on May 15, 1998, the warrant vests with
respect to an additional 5,000 shares. The vested portion of the Chisari
Warrant is exercisable until May 15, 2004 at an exercise price per share of
$3.13. Each of the Burnham Warrant and the Chisari Warrant provides for
accelerated vesting in the event of certain mergers or other similar
transactions that result in a change in control of the Company. Each of the
Burnham Warrant and the Chisari Warrant were issued in a transaction not
involving a public offering and therefore exempt pursuant to Section 4(2) of
the Securities Act.

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 additional 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 related to the European development of the
Company's tgDCC-E1A cancer product and interest income earned on investments.
The Company has generated an accumulated deficit of $67.8 million through
December 31, 1997.
 
  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 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 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.
See "Factors Affecting Forward-Looking Information".
 
RESULTS OF OPERATIONS
 
  Revenue under collaborative agreements decreased to $888,000 for the year
ended December 31, 1997, from $1.2 million for the year ended December 31,
1996. The decrease primarily resulted from a reduction in milestone payments
received under the Company's collaborative agreement with Laboratoires
Fournier S.C.A. ("Fournier"). Similarly, the increase in 1996 versus 1995 was
attributable to receipts from Fournier.
 
  Investment income decreased to $651,000 for the year ended December 31,
1997, from $924,000 for the year ended December 31, 1996. The decrease
resulted from a lower average cash balance and securities available for
investment. The increase in 1996 versus the year ended December 31, 1995 was
attributable to a higher average investment balance during the year and higher
rates of return on those balances.
 
  Research and development expenses increased to $13.0 million for the year
ended December 31, 1997, from $11.5 million for the year ended December 31,
1996. Although internal expenses for research and development leveled off in
1997, the Company experienced an increase in external expenses related to
intellectual property and to the continued progression of the Company's
clinical trial programs. Of the increase, approximately $1.4 million related
to these two areas. The increase in 1996 versus the year ended December 31,
1995 was
 
                                      20
<PAGE>
 
approximately $3.3 million, of which $1.6 million related to the RGene
acquisition and continuation of the acquired research, development and
clinical programs. Of this amount, approximately $1.3 million represented
recurring, routine charges and approximately $300,000 represented non-
recurring charges. Also contributing to the increase in expenses in 1996 over
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.
 
  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
allocated to RGene's existing in-process technology and was written-off in the
second quarter to in-process research and development expense.
 
  General and administrative expenses decreased slightly to $2.8 million for
the year ended December 31, 1997, from $2.9 million for the year ended
December 31, 1996. Consistent with internal research and development expenses,
general and administrative expenses leveled off in 1997. The increase in 1996
expenses versus the year ended December 31, 1995 reflected $338,000 of non-
recurring expenses incurred as a result of the RGene acquisition. Other
factors contributing to the increase in 1996 expenses were increases in
business development and investor relations activities and, to a lesser
extent, modest growth in administrative staff.
 
  Interest expense decreased to $338,000 for the year ended December 31, 1997,
from $397,000 for the year ended December 31, 1996. This expense resulted from
obligations under capital leases used to purchase laboratory and computer
equipment, furniture and leasehold improvements. The decrease from the prior
year was due to a declining principal balance under the related lease
obligations. The increase in 1996 versus the year ended December 31, 1995 was
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, 1997, the Company had cash, cash equivalents and securities
available for sale totaling $5.0 million, compared to $19.1 million at
December 31, 1996. The decrease was primarily attributable to the Company's
use of $12.5 million to fund its operations for the year. Also, $1.3 million
was used for payments under equipment leases and notes and $705,000 was used
for purchases of equipment. These cash outflows were offset partially by the
receipt of $468,000 from equipment financing transactions and $277,000 from
the exercise of warrants by existing shareholders.
 
  In February 1998, the Company reorganized in order to reduce its cash burn
rate, in the process reducing its employee headcount by 29% to approximately
64 full-time equivalent employees. Taking into account the effect of the
reorganization, the Company estimates that its cash, cash equivalents and
securities available for sale at December 31, 1997 will be sufficient to meet
its cash needs until May 1998. Therefore, the Company must raise additional
capital in the near term in order to continue its operations beyond such time.
The Company expects to raise such capital through a private placement of
equity securities. There can be no assurance, however, that the Company will
be successful in completing such a private placement. If the Company is unable
to raise sufficient capital, it may be required to scale back its programs,
dispose of technology or cease operations.
 
  Over the long-term, the Company will need to raise substantial additional
funds in the future to continue the development and commercialization of its
products. The Company's business strategy involves entering into agreements
with corporate partners that provide license fees, milestone payments,
research and development funding and, potentially, equity investment. There
can be no assurance, however, that the Company will be successful in
establishing any such collaborative arrangements or that any such future
partner would be successful in commercializing products. Regardless of its
success in partnering, the Company expects that it will need to seek
additional sources of public or private equity capital in the future. There
can be no assurance that adequate funds will be available to the Company
through such sources when needed or will be available on terms favorable to
the Company. If at any time the Company is unable to obtain sufficient funds,
the Company will be
 
                                      21
<PAGE>
 
required to delay, restrict or eliminate some or all of its research or
development programs, dispose of assets or technology, or cease operations.
 
IMPACT OF YEAR 2000
 
  The Company has completed a computer system assessment and will have to
replace portions of its software so that its computer systems will function
properly with respect to dates in the year 2000 and thereafter. The total Year
2000 project cost is estimated at less than $100,000, which includes
approximately $50,000 for the purchase of new software that will be
capitalized and approximately $50,000 that will be expensed as incurred. To
date, the Company has not incurred any costs for the development of a
modification plan or for the purchase new software. The project is estimated
to be completed no later than June 30, 1999, which is prior to any anticipated
impact on its operating systems.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
The Board of Directors and Shareholders
Targeted Genetics Corporation
 
  We have audited the accompanying balance sheets of Targeted Genetics
Corporation (a development stage company) as of December 31, 1997 and 1996,
and the related statements of operations, shareholders' equity, and cash flows
for each of the three years in the period ended December 31, 1997 and the
period from March 9, 1989 (date of inception) through December 31, 1997. 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 financial position of Targeted Genetics
Corporation (a development stage company) at December 31, 1997 and 1996, and
the results of its operations and its cash flows for each of the three years
in the period ended December 31, 1997 and the period from March 9, 1989 (date
of inception) through December 31, 1997 in conformity with generally accepted
accounting principles.
 
  The accompanying financial statements have been prepared assuming the
company will continue as a going concern. As more fully described in Note 1,
the Company has incurred substantial operating losses and negative operating
cash flows. These conditions raise substantial doubt about the Company's
ability to continue as a going concern. Management's plans in regard to these
matters are also described in Note 1. The financial statements do not include
any adjustments to reflect the possible future effects on the recoverability
and classifications of assets and liabilities that may result from the outcome
of this uncertainty.

                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 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, 1997, Immunex held approximately 13% of the outstanding stock of the
Company.
 
  The Company has incurred operating losses and negative cash flows from
operations each year since inception. As of December 31, 1997, the Company had
an accumulated deficit of $67.8 million. The financial statements have been
prepared assuming the Company will continue as a going concern and do not
include any adjustments to reflect the possible future effects on the
recoverability and classification of assets and liabilities that may result
from the outcome of this uncertainty.
 
  As a result of its significant development efforts, the Company has required
substantial working capital to fund its operations. To date, the Company has
financed it operations principally through the net proceeds from its equity
offerings. As of December 31, 1997, the Company had cash, cash equivalents and
securities available for sale of $5.0 million. The funds will enable the
company to sustain operations until approximately May 1998. The Company is
actively pursuing additional working capital, through a private placement of
equity securities, to meet its future operational requirements. If the Company
is not able to secure additional sources of working capital, it will be forced
to curtail operations or dispose of assets or technology. There can be no
assurance such funds will be available as needed or on terms that are
acceptable to the Company or that the Company will successfully complete other
steps necessary to continue as a going concern.
 
NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
 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 one year. 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.

                  NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 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.
 
 Stock Compensation
 
  The Company has adopted the disclosure-only provisions of Financial
Accounting Standards No. 123 "Accounting for Stock-Based Compensation"
("Statement 123"), whereby it will apply Accounting Principles Board Opinion
No. 25 and related interpretations in accounting for its stock option plan.
Accordingly, the Company's stock-based compensation expense is recognized
based on the intrinsic value of the option on the date of the grant.
Recognition of the stock-based compensation under Statement 123 requires the
use of fair value method to value stock options using option value models
which were developed for purposes other than valuing employee stock options.
 
 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
 
  In February 1997, The Financial Accounting Standards Board issued Statement
No. 128, Earnings Per Share ("Statement 128"). Under Statement 128, the
Company is required to present basic and diluted earnings per share for all
years presented. Basic net loss per share is computed based upon the weighted
average number of common shares outstanding during the period. Diluted net
loss per share includes the impact of stock options, warrants and other
potentially dilutive securities unless the effect of their inclusion would be
antidilutive. There was no restatement required due to the adoption of
Statement 128.
 
 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.

NOTE 6. SHAREHOLDERS' EQUITY
 
 Warrants
 
  In July 1995, the Company issued warrants to purchase 830,598 shares of
common stock in conjunction with an offering of its common stock. At December
31, 1997, 710,332 of such warrants were outstanding and exercisable at a price
of $4.68 per share, expiring January 1998. The Company has issued a total of
137,016 warrants related to equipment financing, collaborative and license
agreements. These warrants have a weighted average price of $4.77 per share
and expire from May 1999 to December 2003. At December 31, 1997, 847,348
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 2,300,000 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, 1997,
options on 464,998 shares were available for future grant.

NOTE 7. ACQUISITION OF RGENE THERAPEUTICS, INC.
 
  On June 19, 1996, the Company completed its acquisition of RGene
Therapeutics, Inc. ("RGene"), a privately-held gene therapy company. The
Company issued 3,636,364 shares of common stock in exchange for all the
outstanding capital stock of RGene. The acquisition was accounted for as a
purchase and the consideration issued by the Company was allocated to RGene's
tangible and intangible assets acquired based on their relative fair values on
the acquisition date. The amount allocated to acquired in-process research and
development was written off to operations in 1996. The allocation of the
aggregate purchase price was as follows:

  The Company may issue up to $5 million in additional common stock to RGene's
former stockholders based on the achievement of certain clinical and business-
related milestones prior to December 31, 1998. The Company has also assumed
certain long-term consulting and research funding agreements as a result of
the merger.
 
NOTE 8. COMMITMENTS
 
  The Company leases its research and office facilities under two
noncancellable operating leases which expire beginning April 1, 1999. The

  In January 1998, four capital leases were extended. As such, the annual
future minimum rental payments for capital leases will be increased by
$244,344, $264,724, $122,697 and $33,847 beginning in 1998, respectively. Rent
expense under operating leases for the years ended December 31, 1997, 1996 and
1995 was $533,155, $432,335 and $396,220, respectively.
 
NOTE 9. EMPLOYEE RETIREMENT PLAN
 
  The Company sponsors an Employee Retirement Plan in accordance with Section
401(k) of the Internal Revenue Code. All employees 21 years old or older are
eligible to participate in the plan. Contributions made into the plan are at
the discretion of the Company's Board of Directors. The Company incurred
$99,426 and $81,364 of expense in 1997 and 1996 related to contributions to
the plan. There were no contributions to the plan made by the Company in 1995.
 
NOTE 10. INCOME TAXES
 
  At December 31, 1997, the Company had net operating loss carryforwards of
$52,547,000 and research and experimental credit carryforwards of $1,439,000.
The carryforwards are available to offset future federal income taxes and
begin to expire in 2008. The Company has provided a valuation allowance to
offset the excess of deferred tax assets over the deferred tax liabilities due
to the uncertainty of realizing the benefits of the net deferred tax asset.
The valuation allowance increased by $5,032,000 and $5,717,000 during 1997 and
1996, respectively.

</TABLE>
 
  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 and issuances 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, 1997, 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.

below, to pay the FOUNDATION funds to entirely support the RESEARCH PROGRAM, and
the FOUNDATION agrees to supply the services of requisite personnel and to
furnish the necessary facilities to carry out such RESEARCH PROGRAM, all
according to a Plan for Research and Budget to be agreed upon by 

                                       4
<PAGE>
 
                              FHCRC-TGC RESEARCH AND EXCLUSIVE LICENSE AGREEMENT



TGC and FHCRC as set forth in Section 2.2. INVESTIGATORS shall be precluded from
conducting any clinical trials in humans under the RESEARCH PROGRAM.

     2.2  FOUNDATION shall annually submit to TGC a proposed Plan for Research
and Budget for each of the three (3) Agreement Years following the Effective
Date of this Agreement (each Agreement Year being defined to mean the twelve-
month period commencing with the Effective Date or anniversary thereof).  The
Plan for Research and Budget for the first Agreement Year shall be negotiated in
good faith by the parties and agreed to on or before June 30, 1994.  For each of
the two Agreement Years thereafter, FOUNDATION shall submit a proposed Plan for
Research and Budget at least ninety (90) days prior to the first and second
anniversaries of the Effective Date.  The parties will negotiate in good faith
and use their best efforts to finalize such Plan for Research and Budget.  If
FOUNDATION and TGC are not able to agree upon the Plan for Research and Budget
after good faith negotiations, TGC may notify FOUNDATION at least sixty (60)
days prior to the beginning of the subsequent Agreement Year that it will not
support the RESEARCH PROGRAM for such year.  Notification less than sixty (60)
days prior to the beginning of the Agreement Year will not be effective.  As its
sole liability upon termination, TGC shall pay FOUNDATION for all reasonable
expenses incurred or committed to be expended as of the effective termination
date up to a maximum of fifty thousand dollars ($50,000).

     2.3  For as long as the INVESTIGATORS remain at FHCRC, the RESEARCH PROGRAM
shall be under their direction.  During the term of this Agreement the
INVESTIGATORS shall not conduct research for other commercial organizations in
the FIELD without the prior written consent of TGC.

     2.4  In the event that the services of Dr. Greenberg or Dr. Riddell become
unavailable during the course of the RESEARCH PROGRAM, under circumstances that
TGC reasonably believes to be permanent, TGC shall have the right to terminate
its obligation to fund the RESEARCH PROGRAM, except that TGC shall be required
to pay FHCRC for reasonable expenses incurred or committed to be expended as of
the termination date up to a maximum of fifty thousand dollars ($50,000).

     2.5  Except as otherwise provided in Section 3.5, termination of the
RESEARCH PROGRAM shall not affect TGC's rights or obligations with respect to
the LICENSED PATENT RIGHTS that have been incorporated and added to this
Agreement as of the date of such termination, and with respect to
commercialization of LICENSED PRODUCTS and LICENSED PROCESSES covered by such
LICENSED PATENT RIGHTS.

                              FHCRC-TGC RESEARCH AND EXCLUSIVE LICENSE AGREEMENT



     2.6  Within thirty (30) days after each anniversary of the Effective Date,
the INVESTIGATORS shall provide TGC a written report of the results of the
RESEARCH PROGRAM obtained during the preceding twelve (12) months.  In the event
of termination of the RESEARCH PROGRAM, TGC shall receive a final summary report
of the work carried out and all inventions conceived of and/or reduced to
practice under the RESEARCH PROGRAM.

     2.7  FOUNDATION shall have the right to subcontract a portion of the work
to be performed under the RESEARCH PROGRAM to the UNIVERSITY subject to
appropriate supervision of such work by the INVESTIGATORS.  The indirect cost
rate applied to such work shall be negotiated in good faith by the parties on or
before June 30, 1994.

                       ARTICLE 3 - INTELLECTUAL PROPERTY

     3.1  FHCRC and TGC will promptly notify the other of any inventions it
becomes aware of, whether or not patentable, that arise out of the RESEARCH
PROGRAM in the FIELD ("INVENTIONS").  INVENTIONS which are conceived solely by
employees of FHCRC shall be assigned to FHCRC ("FHCRC INVENTIONS").  INVENTIONS
which are conceived solely by employees of TGC shall be assigned to TGC.
INVENTIONS which are jointly conceived by employees of FHCRC and TGC shall be
jointly assigned to FHCRC and TGC ("JOINT INVENTIONS").

     3.2  TGC is hereby granted the option to license, under the terms and
conditions stated in this Agreement, all FHCRC INVENTIONS and JOINT INVENTIONS
on an exclusive, worldwide basis.  TGC will have thirty (30) days from the date
it is notified by FHCRC of any INVENTION, or from the date TGC becomes aware of
an INVENTION, as the case may be, to exercise the option by giving written
notice of the election to FHCRC and using its best efforts to take the necessary
steps to file a patent application or other application for intellectual
property protection at the earliest possible time.  Upon exercise of the option,
the patent application or other application for intellectual property protection
which is the subject of such exercised option shall automatically be deemed
incorporated into the LICENSED PATENT RIGHTS.

     3.3  FHCRC, including the INVESTIGATORS, and TGC shall cooperate fully in
the preparation, filing, prosecution and maintenance of LICENSED PATENT RIGHTS
and of all patents and patent applications licensed to TGC hereunder, executing
all papers and instruments or requiring members of FHCRC to execute such papers
and instruments so as to enable TGC to apply for, to prosecute and to maintain
patent applications and patents in FHCRC's name in any country.

<PAGE>
 
                              FHCRC-TGC RESEARCH AND EXCLUSIVE LICENSE AGREEMENT


Each party shall provide the other prompt notice as to all matters which come to
its attention and which may affect the preparation, filing, prosecution or
maintenance of any such patent applications or patents. TGC shall bear all costs
incurred in connection with such preparation, filing, prosecution and
maintenance of all LICENSED PATENT RIGHTS foreign and domestic; provided that
TGC shall first consult with FHCRC as to the preparation, filing, prosecution
and maintenance of such patent applications and patents. TGC shall keep FHCRC
advised as to all developments with respect to all patent applications and
patents included in LICENSED PATENT RIGHTS and shall promptly supply to FHCRC:
(i) copies of all official correspondence from the U.S. Patent Office or from a
patent office in any country within two weeks of receipt; and (ii) copies of all
substantive papers to be filed in the U.S. Patent Office or a patent office in
any country at least thirty (30) days prior to filing to provide FHCRC
sufficient time to comment thereon. Up to twenty thousand dollars ($20,000) in
patent prosecution and interference expenses reasonably incurred by TGC for each
of the initial patent applications filed by TGC in the U.S. Patent and Trademark
Office for Inventions (i.e., continuations, continuations-in-part and divisions
are excluded for the purposes of calculating this credit) and included in the
LICENSED PATENT RIGHTS may be credited against royalties due by FHCRC under
Section 6.2, but such credit will not reduce the amount which would otherwise be
due FHCRC in any year by more than 50%. Any unused credit amount may be carried
forward by TGC each year until the full amount of the credit has been exhausted.

     3.4  So long as TGC is not in default or in breach of this Agreement, FHCRC
grants to TGC an option to license any invention developed under the RESEARCH
PROGRAM that is not in the FIELD.  The parties shall exercise their good faith
best efforts to negotiate commercially reasonable terms based on the relative
contribution to such inventions and the commercial value thereof.  The option
granted by this Section 3.4 may be exercised by TGC by giving written notice to
FHCRC within ninety (90) days from the date of disclosure of the invention.  If
the option is not exercised within the ninety (90) day period, it will expire.

     3.5  If TGC fails to financially support the preparation, filing,
prosecution or maintenance of any patent application, patent or other
intellectual property included in the LICENSED PATENT RIGHTS, TGC shall have
deemed to have surrendered its rights under such patent application, patent or
other intellectual property.  In that event, FHCRC may, at its sole expense,
prepare, file, continue prosecution over or maintain any such patent
application, patent or other intellectual property protection.

                              FHCRC-TGC RESEARCH AND EXCLUSIVE LICENSE AGREEMENT

                               ARTICLE 4 - GRANT

     4.1  FHCRC hereby grants to TGC and TGC accepts, subject to the terms and
conditions hereof:  (a) an exclusive, worldwide license to make, to have made,
to use, to sell and to have sold LICENSED MATERIALS; and (b) an exclusive
worldwide license, under LICENSED PATENT RIGHTS, to make, to have made, to use,
to sell, and to have sold LICENSED PRODUCTS, and to practice the LICENSED
PROCESSES, for the Term permitted in Article 5 of this Agreement (the
"License").  The License granted to TGC by FHCRC hereunder is limited to the
FIELD.  Any license in any other field (including with respect to FHCRC
INVENTIONS and JOINT INVENTIONS) shall be the subject of a separate agreement
and shall require TGC's submission of evidence demonstrating its willingness and
ability to develop and commercialize the kinds of products or processes likely
to be encompassed in such other field.  The License includes the right to grant
sublicenses, subject to the provisions of Section 4.2(e) below.  TGC agrees
during the period of exclusivity of this license in the United States that any
LICENSED PRODUCT produced for sale in the United States will be manufactured
substantially in the United States.

     4.2  The License is subject to the following policies, obligations and/or
conditions:

          (a)  FHCRC's Patents and Inventions Policy adopted September 30, 1983,
               Public Law 98-620 and FHCRC's obligations under agreement with
               other sponsors of research.  Any right granted in this Agreement
               greater than that permitted under Public Law 98-620 shall be
               subject to modification as may be required to conform to the
               provisions of the statute.

          (b)  For research purposes only and not for any commercial purpose,
               FHCRC retains the right to practice LICENSED PROCESSES in the
               FIELD, to make and to use LICENSED MATERIALS, and to grant non-
               exclusive licenses of these same rights to other not-for-profit
               organizations for noncommercial research purposes only ("Research
               License").  In the event that TGC can provide convincing written
               evidence to FHCRC that a not-for-profit organization that has
               been granted a Research License is developing inventions either
               solely or in collaboration with a third party for commercial
               manufacture or in lieu of purchase if the inventions are
               available as commercial products, then TGC can request that FHCRC
               terminate its Research License with 

                                       8

               such organization, such request not to be unreasonably withheld.

          (c)  TGC shall use its best efforts to introduce the LICENSED PRODUCTS
               into the commercial market as soon as practicable, consistent
               with sound and reasonable business practices and judgment, and
               thereafter endeavor to keep LICENSED PRODUCTS reasonably
               available to the public.

          (d)  FHCRC shall have the right to terminate or render the License
               granted under this Agreement non-exclusive at any time after
               three (3) years from the EFFECTIVE DATE, if in FHCRC's reasonable
               judgment, TGC:

               (i)  has not put the licensed subject matter into commercial use
                    in the country or countries where licensed, directly or
                    through a sublicense, and is not keeping the licensed
                    subject matter reasonably available to the public, or

               (ii) is not demonstrably engaged in research, development,
                    manufacturing, marketing or licensing program, as
                    appropriate, directed toward these ends; or

               (iii)  has not expended at least three hundred thousand dollars
                    ($300,000) in the twelve (12) month period beginning three
                    (3) years from the EFFECTIVE DATE, or in any (12) twelve
                    month period beginning anytime thereafter, on internal and
                    external personnel, their benefits, supplies and equipment,
                    related to research and development of the LICENSED
                    PRODUCTS.

               In making this determination FHCRC shall take into account the
               normal course of such programs conducted with sound and
               reasonable business practices and judgment and shall take into
               account the reports provided hereunder by TGC.

          (e)  TGC shall not grant any sublicense without FHCRC's prior written
               consent, such consent not to be unreasonably withheld.  All
               sublicenses granted by TGC hereunder shall include a requirement
               that the sublicensee use its best efforts to bring the subject
               matter of the sublicense into commercial use as quickly as is
               reasonably possible, shall comply with Section 10.5 of this
               Agreement, and shall expressly bind the sublicensee to meet

               TGC's obligations to FHCRC under this Agreement. Copies of all
               sublicense agreements shall promptly be provided to FHCRC.

          (f)  In the event FHCRC becomes aware of third parties that wish to
               license the LICENSED PATENT RIGHTS in specific fields of use that
               would not result in direct or indirect competition to TGC, FHCRC
               shall notify TGC and TGC shall exercise one of the following
               options:

               (i)  commence active research and development of LICENSE PRODUCTS
                    under the LICENSED PATENT RIGHTS in that field of use;

               (ii) grant a sublicense to said third parties to make, use and
                    sell LICENSED PRODUCTS under the LICENSED PATENT RIGHTS in
                    that field of use; or

               (iii)  grant the right to FHCRC to directly license said third
                    parties to make, use and sell LICENSED PRODUCTS under the
                    LICENSED PATENT RIGHTS in that field of use.

     4.3  Notwithstanding the foregoing provisions of Article 4, TGC shall have
the right to assign the license granted under Article 4 to an AFFILIATE or to
any organization that acquires all or substantially all of TGC's business,
subject to the terms and conditions hereof.

     4.4  This Agreement shall have no effect upon any and all rights reserved
to the United States Government and others under Public Law 98-620.

                         ARTICLE 5 - TERM OF AGREEMENT

     5.1  This Agreement becomes effective as of the date first above written
(the "Effective Date"), and, subject to earlier termination as provided in
Article 10, shall remain in effect until the last to expire of the LICENSED
PATENT RIGHTS (the "Term").

                             ARTICLE 6 - ROYALTIES

     6.1  In consideration for the granting of the License, TGC shall pay to
FHCRC a non-refundable license fee ("Upfront Fee") in the sum of [          *

     6.2(a)  During the Term, TGC shall pay to FHCRC a royalty in the amount of

products using LICENSED PROCESSES and all services utilizing LICENSED PRODUCTS
or LICENSED PROCESSES which are sold by TGC and its AFFILIATES or sublicensees
on a country-by-country basis ("FHCRC Royalties").

     6.2(b)  Notwithstanding the foregoing, if TGC is required to pay royalties
to an unaffiliated third party(ies) for sales of LICENSED PRODUCTS or to
practice LICENSED PROCESSES for which payments are also due to FHCRC ("Third
Party Royalties"), then the royalties be paid by TGC to FHCRC shall be reduced
by the amount that the sum of the FHCRC Royalties and Third Party Royalties are
in excess of [          *          ] of NET SALES of LICENSED PRODUCTS, but in
no event shall the FHCRC Royalties be reduced to less than 
[          *          ] of NET SALES of LICENSED PRODUCTS.

     6.3  TGC shall pay to FHCRC at least the following amounts in royalties in
the following contract years (the "Maintenance Royalties"):

               thereof, or June 30, 1996.  Notwithstanding the foregoing, in the
               event that such patent issues with claims that [          *
               ], or if such claims are not pending in the patent application as
               of June 30, 1996, then the amount due under this Article 6.3(a)
               shall be reduced to [          *          ];

          (b)  [          *          ], due upon issuance of any patent included
               in the LICENSED PATENT RIGHTS relating to methods for expanding T
               cells, on which patent the INVESTIGATORS are named as inventors.

               amounts actually paid to FHCRC under this Article 6.3

     6.5  If TGC transfers or otherwise sublicenses LICENSED PATENT RIGHTS to a
third party, for value other than NET SALES, TGC shall also pay FHCRC a
percentage of [          *          ] of all proceeds including, but not limited
to, licensing fees, receivable by TGC in connection therewith ("Non-Royalty
Fees").  Any such payment to FHCRC shall be made within thirty (30) days after
receipt of such proceeds by TGC.  Any such sale or transfer shall not affect
TGC's obligations to pay royalties under Sections 6.2 and 6.3 above.  In no
event shall Non-Royalty Fees include any payment or other value due to or
received by TGC from a third party as, for example, an upfront fee, research and
development payments, milestone payments, equity, or any equivalent of the
foregoing, or of any payment that is not explicitly due to or received by TGC in
consideration for a grant by TGC to a third party to make, have made, use and
sell LICENSED PRODUCTS, or practice LICENSED PROCESSES, under LICENSED PATENT
RIGHTS.

     In the event that TGC transfers or otherwise sublicenses LICENSED PATENT
RIGHTS to a third party in combination with patents(s) and/or other rights(s) of
a third party(ies) and TGC is due and receives Non-Royalty Fees, then TGC shall
pay FHCRC an equitable portion of such Non-Royalty Fees as to be determined by
the good faith negotiations of TGC and FHCRC.

                ARTICLE 7 - REPORTING AND ROYALTY PAYMENT TERMS

     7.1  Upon or before execution of this Agreement, TGC shall provide to FHCRC
a written research and development plan pursuant to which TGC intends to bring
the subject matter of the License granted hereunder into commercial use,
including projections of sales and proposed marketing efforts.

     7.2  TGC shall report to FHCRC the date of first sale of LICENSED PRODUCTS
(or results of LICENSED PROCESSES) in each country within thirty (30) days of
occurrence.

     7.3  TGC shall provide written annual reports within sixty (60) days after
December 31 of each calendar year which shall include the following information:
reports of progress on research and development, regulatory approvals,
manufacturing, sublicensing, marketing and sales during the preceding twelve
(12) months as plans for the coming year.  If TGC's progress differs from that

in the plan provided to FHCRC under Section 7.1, TGC shall explain the reasons
for the difference and propose a modified plan for FHCRC's review and approval.
TGC shall also provide any reasonable additional data FHCRC requires to evaluate
TGC's performance.

     7.4  Beginning with the first NET SALES, TGC shall submit to FHCRC within
sixty (60) days after June 30 and December 31 of each calendar year during the
Term, and upon the effective termination of this Agreement, reports for the
preceding six (6) month period identifying the amount of the LICENSED PRODUCTS
sold by TGC, its AFFILIATES and sublicensees in each country, the sales volume
and NET SALES, and the amount of royalty due to FHCRC together with payment of
such royalty amount.  Such report shall be certified as correct by an officer of
TGC and shall include a detailed listing of all deductions from NET SALES,
sublicensee income or from royalties as specified herein.  If no royalties are
due to FHCRC for any reporting period, the written report shall so state.  All
royalties due hereunder shall be payable in United States dollars.  Conversion
of foreign currency to U.S. dollars shall be made at the conversion rate
existing in the United States on the date the royalty payments by TGC are due as
quoted in the Wall Street Journal for that day.

     7.5  All such reports shall be maintained in confidence by FHCRC, except as
otherwise required by law, including Public Law 98-620.

                           ARTICLE 8 - RECORD KEEPING

     8.1  TGC shall maintain complete and accurate books of account and records
showing all sales of LICENSED PRODUCTS and all NET SALES (broken down by gross
sales and allowable deductions) attributable to such sales.  For purposes of
verifying the accuracy of the royalties paid by TGC pursuant to this Agreement
or verifying performance of TGC of any other obligation to FHCRC or the
FOUNDATION hereunder, such books and records shall be open to inspection and
copying, during usual business hours, by an independent certified public
accountant mutually agreeable to the parties.  Such accountant shall not
disclose to FHCRC any information other than information relating to accuracy of
reports and calculations of amounts due to FHCRC made under this Agreement.  In
the event that any such inspection shows any underreporting and underpayment by
TGC in excess of five percent (5%) for any twelve (12) month period, then TGC
shall pay the cost of such examination.  Such books and records shall be
maintained for at least two (2) full years after the termination of this
Agreement.

                            ARTICLE 9 - INFRINGEMENT

     9.1  Each party agrees to notify the other promptly of any infringement of
the LICENSED PATENT RIGHTS of which such party becomes aware.  TGC shall have
the option to commence legal proceedings with respect to such infringement.
Before TGC commences legal proceedings (an "Action") with respect to any
infringement of such patents, TGC shall give careful consideration to the views
of FHCRC and to potential effects on the public interest in making its decision
whether or not to commence such an Action.

     9.2  If TGC elects to commence an Action as described above, TGC may
reduce, by up to fifty percent (50%), the royalty due to FHCRC earned under the
patent subject to suit by the amount of the expenses and costs of such Action,
including attorney fees.  In the event such expenses and costs exceed the amount
of royalties withheld by TGC for any calendar year, TGC may to that extent
reduce the royalties due to FHCRC from TGC in succeeding calendar years, but
never by more than fifty percent (50%) of the royalty due in any one year.  Any
unused royalty credit amount may be carried forward until the full amount of the
credit has been exhausted.

     9.3  Recoveries or reimbursements from such Action shall first be applied
to reimburse TGC and FHCRC for litigation costs not paid from royalties (if any)
and then to reimburse FHCRC for royalties withheld.  Any remaining recoveries or
reimbursements shall be shared equally by TGC and FHCRC.

     9.4  In the event that TGC elects not to exercise its option to prosecute
an infringement of the LICENSED PATENT RIGHTS pursuant to this Agreement, FHCRC
may do so at its own expense, controlling such Action and retaining all
recoveries therefrom.

                     ARTICLE 10 - TERMINATION OF AGREEMENT

     10.1  Unless terminated earlier in accordance with the terms hereof, this
Agreement will expire upon the expiration of the Term as provided in Article 5.
Upon termination, a final report shall promptly be submitted in accordance with
the provisions of Section 7.4, together with any royalty payments and
unreimbursed patent expenses due to FHCRC.

     10.2  At FHCRC's option, FHCRC may terminate this Agreement sixty (60) days
after giving written notice to TGC of any default in payments due hereunder and
subsequent failure by TGC to remedy and such default within such period,
provided that FHCRC is not then in breach of any provision hereof.

     10.3  This Agreement may be terminated by either party upon breach of a
material obligation or condition by the other (other than a breach according to
Section 10.2), effective ninety (90) days after giving written notice to the
other of such termination under this Article and specifying such breach,
provided however, that if the breach is cured or shown to be non-existent within
the ninety (90) day period, the notice shall be deemed automatically withdrawn
and of no effect.  If the parties do not agree whether a breach has occurred or
been cured or whether it is "material", the dispute shall be resolved through
arbitration under Article 14.

     10.4  Subject to any provisions of the federal bankruptcy laws limiting
rights of termination, this Agreement will automatically terminate if TGC files
for protection under federal bankruptcy laws, becomes insolvent, makes an
assignment for the benefit of creditors, appoints or suffers appointment of a
receiver or trustee over its property, files a petition under any bankruptcy or
insolvency act or has any such petition filed against it or files for
dissolution.

     10.5  Any sublicenses granted by TGC under this Agreement shall provide for
termination or assignment to FHCRC, at the option of FHCRC, of TGC's interest
therein upon termination of this Agreement.

     10.6  TGC shall have the right to terminate this Agreement effective thirty
(30) days after giving written notice to FHCRC of termination under this
Article, except that TGC shall have continuing obligations to FHCRC in
accordance with Sections 2.2 and 2.4 hereof.

     10.7  Upon termination of this Agreement, TGC shall have the right for
three (3) months to sell all LICENSED PRODUCTS on hand at the time of
notification of termination if the royalties from such sales and any and all
other payments due FHCRC are paid to and statements rendered to FHCRC with
respect to such LICENSED PRODUCTS when due in accordance with this Agreement.

     10.8  Upon termination of the Agreement for any reason, and subject to
TGC's rights under Section 10.7, TGC shall return to FHCRC and thereafter
continue to maintain the confidentiality thereof, and refrain from use thereof
or the disclosure thereof to any third party as required by Article 16, and all
other rights in LICENSED MATERIALS, LICENSED PROCESSES and LICENSED PRODUCTS
granted to TGC under Article 4 shall expire and revert to FHCRC.  Immediately
upon cessation of discussions between TGC and FHCRC during the Term, or upon
request by one of the parties, TGC and FHCRC will return all Proprietary
Information of the other, and all documents or data storage media containing any
such Proprietary Information and any and all copies thereof, and TGC and FHCRC
will delete all Proprietary Information of the other from its documents or data

Proprietary Information in their legal or corporate development files.


     10.9  Should either party terminate this Agreement as permitted herein, the
other party shall not be able to claim from the terminating party any damages or
compensation for losses or expenses incurred solely as a result of the
termination.

     10.10  Provisions hereof and accrued rights hereunder which by their terms
or nature survive the termination or expiration of this Agreement shall so
survive such termination or expiration.

                   ARTICLE 11 - REPRESENTATIONS AND COVENANTS

     11.1  FHCRC represents and warrants that all right, title, and interest in
the patent applications or patents comprising the LICENSED PATENT RIGHTS,
LICENSED PROCESSES and LICENSED MATERIALS have been assigned to it, or are
otherwise owned by it, and that FHCRC has the authority to issue licenses under
said LICENSED PATENT RIGHTS, LICENSED PROCESSES and LICENSED MATERIALS.  FHCRC
disclaims all implied or express warranties of any nature whatsoever concerning
the validity of the LICENSED PATENT RIGHTS, LICENSED PROCESSES and LICENSED
MATERIALS licensed hereunder.  TGC acknowledges and agrees that neither FHCRC
nor anyone acting on its behalf has made any representations or warranties and
expressly disclaims whatsoever with regard to the scope of the LICENSED PATENT
RIGHTS, LICENSED PROCESSES or the LICENSED MATERIALS, or that such LICENSED
PATENT RIGHTS, LICENSED PROCESSES and LICENSED MATERIALS may be exploited by
TGC, an AFFILIATE, or sublicensee without infringing other patents.

     11.2  FHCRC EXPRESSLY DISCLAIMS ANY AND ALL EXPRESS WARRANTIES, EXCEPT
THOSE STATED IN THIS ARTICLE 11, AND FURTHER DISCLAIMS ANY AND ALL IMPLIED
WARRANTIES OF MERCHANTABILITY OR FITNESS OF THE LICENSED PROCESSES, LICENSED
MATERIALS OR LICENSED PRODUCTS FOR ANY PARTICULAR USE OR PURPOSE.

     11.3  TGC represents and warrants to FHCRC that it has obtained and will at
all times during the Term of this Agreement, hold and comply with all licenses,
permits and authorizations necessary to TGC'S complete and timely performance of
its obligations under this Agreement which are required under any applicable
statutes, laws, ordinances, rules and regulations of the United States as well

asserting or claiming jurisdiction over TGC or TGC's performance of the terms of
this Agreement. In particular, TGC:

          (a)  will be responsible for obtaining all necessary United States
               Food and Drug Administration approvals and all approvals required
               by similar governmental bodies or agencies of all applicable
               foreign countries; and

          (b)  understands and acknowledges that the transfer of certain
               commodities and technical data is subject to United States laws
               and regulations controlling the export of such commodities and
               technical data, including all Export Administration Regulations
               of the United States Department of Commerce.  These laws and
               regulations, among other things, prohibit or require a license
               for the export of certain types of technical data to certain
               specified countries.  TGC hereby agrees and gives written
               assurance that it will comply with all United States laws and
               regulations controlling the export of commodities and technical
               data, that it will be solely responsible for any violation of
               such by TGC or its AFFILIATES or sublicensees, and that it will
               defend and hold FHCRC harmless in the event of any legal action
               of any nature occasioned by such violation.

                           ARTICLE 12 - LEGAL ACTION

     12.1  In the event any legal action is commenced against TGC involving the
use by TGC of a LICENSED MATERIAL, LICENSED PROCESS or LICENSED PRODUCT, or
otherwise relating to this Agreement, whether or not FHCRC is named as a party
to the legal action, TGC shall keep FHCRC or its attorney nominee fully advised
of the progress of the legal action and shall reimburse FHCRC for its reasonable
legal costs (including attorney's fees) incurred as a result of FHCRC's
monitoring of such action, FHCRC's being named a party to any such legal action,
or when FHCRC's employees or agents are called as witnesses therein or asked to
testify for or consult with TGC in connection therewith.

     12.2  In the event that any legal action is commenced against FHCRC
involving the RESEARCH PROGRAM which is caused by the negligent or wrongful acts
of FHCRC or its employees or agents, whether or not TGC is named as a party to
the legal action, FHCRC shall keep TGC or its attorney nominees fully advised of
the progress of the legal action, and shall reimburse TGC for its reasonable
legal costs (including attorney's fees) incurred as a result of TGC's monitoring

other party will at all times be and remain the sole property of the disclosing
party and the disclosing party is the sole owner of all patents, copyrights and
other intellectual property rights and other proprietary rights related to the

disclosure is first submitted in manuscript or other written form to TGC for
review, comment, consideration of appropriate patent action, and removal of
Proprietary Information, at least thirty (30) days prior to any submission or
other public disclosure. TGC may request an additional delay not to exceed forty
five (45) days so that a patent application can be filed or other appropriate
steps taken to protect Proprietary Information.

                           ARTICLE 19 - MISCELLANEOUS

     19.1  The rights and obligations of the parties under this Agreement shall
be governed by and construed in accordance with the laws of the State of
Washington.

     19.2  This Agreement may not be amended except by an instrument in writing
signed by both parties.

     19.3  The Agreement shall be binding on the parties hereto and upon their
respective heirs, administrators, successors and assigns.  This Agreement may
not be assigned or sublicensed by TGC or by operation of law without the prior
written consent of FHCRC.

     19.4  TGC acknowledges that FHCRC is a non-profit organization qualifying
for and holding the status of an exempt organization under Section 501(c)(3) of
the United States Internal Revenue Code.  If the Internal Revenue Service
determines, or a determination by FHCRC based on advice of legal or tax counsel
is reasonably made, that any part or all of this Agreement will jeopardize
FHCRC's Section 501(c)(3) status, the parties agree to meet and confer in good
faith to amend this Agreement to the extent necessary to satisfy Internal
Revenue Service requirements for retention of FHCRC'S Section 501(c)(3) status.
If FHCRC and TGC cannot agree within 30 days after commencing negotiations
regarding the amendments to be made to this Agreement in order for FHCRC to
retain its Section 501(c)(3) status, FHCRC may terminate this Agreement
effective upon giving written notice to TGC of termination under this Article
19.

     19.5  TGC understands and acknowledges that agreements between FHCRC and
agencies of the United States Government funding FHCRC's programs may contain
clauses granting patent and/or other rights to the agencies or the U.S.
Government; TGC agrees that the rights granted to it under this Agreement shall
be subject to any rights of the agencies and the U.S. Government.  In the event
of a conflict between any of the provisions of this Agreement and the provisions
of any U.S. Government agency funding agreement and/or regulation shall prevail
and FHCRC will have no liability to TGC as a result of such conflict.

                              FHCRC-TGC RESEARCH AND EXCLUSIVE LICENSE AGREEMENT

     19.6  Except as otherwise provided herein, FHCRC and its employees,
including but not limited to the INVESTIGATORS, shall not use the name of TGC,
its employees or agents, and TGC, including its employees, shall not use the
name of FHCRC or any of its employees or agents in any advertising, publicity,
news release, promotional materials or any public disclosure, whatsoever, EITHER
WRITTEN OR ORAL, related to the existence of this Agreement or any actions or
work undertaken pursuant to terms of this Agreement without the prior written
consent of the other party.  FHCRC shall have three (3) business days from the
time it receives a proposed disclosure ("Review Period") to approve and/or
provide comments to TGC with respect to such disclosure.  In the event that TGC
receives no communications from FHCRC regarding such disclosure within the
Review Period, then FHCRC's consent of the public release of such disclosure
shall be deemed to have been granted.

     19.7  Upon the earlier of any:  (i) testing or use in human subjects or
(ii) sale of a LICENSED PRODUCT, TGC will have FHCRC named as an additional
insured on TGC'S product liability insurance policies, with limits of at least
$1,000,000 per claim and $5,000,000 annual aggregate.  Such policies shall not
be terminated without thirty (30) days prior written notice to FHCRC.  If
FHCRC's insurance costs can be shown to have increased solely because of this
Agreement, and such increases are verified by an independent certified public
accountant, TGC shall reimburse FHCRC for such increase within twenty (20) days
of receiving written notice from FHCRC requesting such reimbursement and the
parties shall attempt to agree to changes and revisions of this Agreement.  If
the parties fail to arrive at agreement within a reasonable time, or TGC does
not reimburse FHCRC, FHCRC may by written notice terminate this Agreement.

     19.8  All letters, documents, or other materials of a written or physical
nature, required by or relating to this Agreement shall be in English and sent
to the party at the address given in Article 15.

     19.9  The parties to this Agreement recognize and agree that each is
operating as an independent contractor and not as an agent of the other.  This
Agreement shall not constitute a partnership or joint venture, and neither party
may be bound by the other to any contract, arrangement or understanding except
as specifically stated herein.

     19.10  Should a court of competent jurisdiction later consider any
provision of this Agreement to be invalid, illegal, or unenforceable, it shall
be considered severed from this Agreement.  All other provisions, rights and
obligations shall continue without regard to the severed provision, provided
that the remaining provisions of this Agreement are in accord with the intention
of the parties.

     19.11  In the event any party to this Agreement commences any action or
proceeding, including an appeal of an action or proceeding, against the other,
or otherwise retains an attorney, by reason of any breach or claimed breach of
any provision of this Agreement, or to seek a judicial declaration of rights
hereunder or judicial or equitable relief, the prevailing party in such action
or proceeding shall be entitled to recover its reasonable attorneys' fees and
costs.  At the option of FHCRC, venue of any such legal or equitable action
shall lie in Seattle, Washington.  TGC hereby submits to the jurisdiction of the
Federal District Court of Western Washington located in Seattle, Washington, and

requested, effective upon delivery to TGC.

     IN WITNESS WHEREOF, the parties have executed this Agreement through duly
authorized representatives as of the date first above written.

     PHS and Licensee agree as follows:

1.   BACKGROUND
     ----------

     1.01   In the course of conducting biomedical and behavioral research, PHS
            investigators made inventions that may have commercial
            applicability.

     1.02   By assignment of rights from PHS employees and other inventors,
            DHHS, on behalf of the United States Government, owns intellectual
            property rights claimed in any United States and foreign patent
            applications or patents corresponding to the assigned inventions.
            DHHS also owns any tangible embodiments of these inventions actually
            reduced to practice by PHS.

     1.03   The Assistant Secretary for Health of DHHS has delegated to PHS the
            authority to enter into this Agreement for the licensing of rights
            to these inventions under 35 U.S.C. (S)(S) 200-212, the Federal

            through commercialization licenses to facilitate the commercial
            development of products and processes for public use and benefit.

     1.05   Licensee desires to acquire commercialization rights to certain of
            these inventions in order to develop processes, methods, or
            marketable products for public use and benefit.

            conditions of this Agreement, an exclusive license to Licensee under
            the Licensed Patent Rights in the Licensed Territory to make and
            have made, to use and have used, and to sell and have sold any
            Licensed Products in the Licensed Fields of Use and to practice and
            have practiced any Licensed Processes in the Licensed Fields of Use.

     3.02   This Agreement confers no license or rights by implication,
            estoppel, or otherwise under any patent applications or patents of
            PHS other than Licensed Patent Rights regardless of whether such
            patents are dominant or subordinate to Licensed Patent Rights. 

4.   SUBLICENSING
     ------------

     4.01   Upon written approval by PHS, which approval will not be
            unreasonably withheld, Licensee may enter into sublicensing
            agreements under the Licensed Patent Rights.

     4.02   Licensee agrees that any sublicenses granted by it shall provide
            that the obligations to PHS of Paragraphs 5.01-5.05, 8.01, 10.01,
            10.02, 12.05, and 13.08-13.11 of this Agreement shall be binding
            upon the sublicensee as if it were a party to this Agreement.
            Licensee further agrees to attach copies of these Paragraphs to all
            sublicense agreements.

                                       4
<PAGE>
 
     4.03   Any sublicenses granted by Licensee shall provide for the
            termination of the sublicense, or the conversion to a license
            directly between such sublicensees and PHS, at the option of the
            sublicensee, upon termination of this Agreement under Article 13.
            Such conversion is subject to PHS approval and contingent upon
            acceptance by the sublicensee of the remaining provisions of this
            Agreement.

     4.04   Licensee agrees to forward to PHS a copy of each fully executed
            sublicense agreement postmarked within sixty (60) days of the
            execution of such agreement.

5.   STATUTORY AND PHS REQUIREMENTS AND RESERVED GOVERNMENT RIGHTS
     -------------------------------------------------------------

     5.01   PHS reserves on behalf of the Government an irrevocable,
            nonexclusive, nontransferable, royalty-free license for the practice
            of all inventions licensed under the Licensed Patent Rights
            throughout the world by or on behalf of the Government and on behalf
            of any foreign government or international organization pursuant to
            any existing or future treaty or agreement to which the Government
            is a signatory.

     5.02   Licensee agrees that products used or sold in the United States
            embodying Licensed Products or produced through use of Licensed
            Processes shall be manufactured substantially in the United States,
            unless a written waiver is obtained in advance from PHS.

     5.03  Licensee acknowledges that PHS may enter into future Cooperative
            Research and Development Agreements (CRADAs) under the Federal
            Technology Transfer Act of 1986 that relate to the subject matter of
            this Agreement.  Licensee agrees not to unreasonably deny requests
            for sublicense or cross-license rights from such future
            collaborators with PHS when acquiring such derivative rights is
            necessary in order to make a CRADA project feasible.  Licensee may
            request an opportunity to join as a party to the proposed CRADA.

     5.04   DHHS has responsibility for funding basic biomedical research, for
            funding medical treatment through programs such as Medicare and
            Medicaid, for providing direct medical care and, more generally, for
            protecting the health and safety of the public.  Because of these

                                       5
<PAGE>
 
            responsibilities, and the public investment in the research that
            culminated in the Licensed Patent Rights, PHS may require Licensee
            to submit documentation in confidence showing a reasonable
            relationship between the pricing of a Licensed Product, the public
            investment in that product, and the health and safety needs of the
            public.  This paragraph shall not restrict the right of Licensee to
            price a Licensed Product or Licensed Process so as to obtain a
            reasonable profit for its sale or use.  This Paragraph 5.04 does not
            permit PHS to set or dictate prices for Licensed Products or
            Licensed Processes.

     5.05   In addition to the reserved license of Paragraph 5.01 above, PHS
            reserves the right to grant nonexclusive licenses to make and to use
            the inventions defined by the Licensed Patent Rights for purposes of
            research involving the inventions themselves, and not for purposes
            of commercial manufacture or in lieu of purchase if the inventions
            are available as commercial products for research purposes.  The
            purpose of this research license is to encourage basic research,
            whether conducted at an academic or corporate facility.  In order to
            safeguard the Licensed Patent Rights, however, PHS shall consult
            with Licensee before granting to commercial entities a research
            license or providing to them research samples of the materials
            claimed in the Licensed Patent Rights.

6.   ROYALTIES AND REIMBURSEMENT
     ---------------------------

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

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

     6.03   Licensee agrees to pay PHS earned royalties as set forth in Appendix
            C.

                                       6
<PAGE>
 
     6.04   Licensee agrees to pay PHS benchmark royalties as set forth in
            Appendix C.

     6.05   A claim of a patent or patent application licensed under this
            Agreement shall cease to fall within the Licensed Patent Rights for
            the purpose of computing the minimum annual royalty and earned
            royalty payments in any given country on the earliest of the dates
            that a) the claim has been abandoned but not continued, b) the
            patent expires, c) the patent is no longer maintained by the
            Government, or d) all claims of the Licensed Patent Rights have been
            held to be invalid or unenforceable by an unappealed or unappealable
            decision of a court of competent jurisdiction or administrative
            agency.

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

     6.07   On sales of Licensed Products by Licensee to sublicensees or
            affiliated parties or on sales made in other than an arm's-length
            transaction, the value of the Net Sales attributed under this
            Article 6 to such a transaction shall be that which would have been
            received in an arm's-length transaction, based on sales of like
            quantity and quality products on or about the time of such
            transaction.

     6.08   As an additional royalty, Licensee agrees to pay PHS, within sixty
            (60) days of PHS's submission of a statement and request for
            payment, an amount equivalent to all reasonable expenses previously
            incurred by PHS in the preparation, filing, prosecution, and
            maintenance of Licensed Patent Rights.  Licensee further agrees to
            pay PHS annually, within sixty (60) days of PHS's submission of a
            statement and request for payment, a royalty amount equivalent to
            all such future patent expenses incurred during the previous
            calendar year, as of the date the statement and request for payment
            is sent by PHS to Licensee.  Fifty percent (50%) of the cumulative
            amount of such payments may be credited against royalties due under
            Paragraph 6.03; however, the net royalty payment in any calendar
            year may not be lower than the minimum annual royalty specified in
            Appendix B.  Licensee may elect to surrender its rights in any
            country of the Licensed Territory under any Licensed Patent Rights
            upon sixty (60) days' written notice to PHS and owe no payment
            obligation under this paragraph for subsequent patent-related
            expenses incurred in that country.

7.   DOMESTIC AND FOREIGN PATENT FILING, PROSECUTION, AND MAINTENANCE
     ----------------------------------------------------------------

     7.01   PHS agrees to take responsibility for, but to consult with the
            Licensee in, the preparation, filing, prosecution, and maintenance
            of any and all patent applications or patents included in the
            Licensed Patent Rights and shall furnish copies of relevant patent-
            related documents to Licensee.

     7.02   Each party shall promptly inform the other as to all matters that
            come to its attention that may affect the preparation, filing,
            prosecution, or maintenance of the Licensed Patent Rights and permit
            each other to provide comments and suggestions with respect to the
            preparation, filing, and prosecution of Licensed Patent Rights,
            which comments and suggestions shall be considered by the other
            party.

8.   RECORD KEEPING
     --------------

     8.01   Licensee agrees to keep accurate and correct records of Licensed
            Products made, used, or sold and Licensed Processes practiced under
            this Agreement appropriate to determine the amount of royalties due
            PHS.  Such records shall be retained for at least five (5) years
            following a given reporting period.  They shall be available during
            normal business hours for inspection at the expense of PHS by an
            accountant or other designated auditor selected by PHS for the sole
            purpose of verifying reports and payments hereunder.  The accountant
            or auditor shall only disclose to PHS information relating to the
            accuracy of reports and payments made under this Agreement.  If an
            inspection shows an underreporting or underpayment in excess of five
            percent (5%) for any twelve (12) month period, then Licensee shall
            reimburse PHS for the cost of the inspection at the time Licensee
            pays the unreported royalties, including any late charges as
            required by Paragraph 7.06 of this Agreement.  All payments required
            under this Paragraph shall be due within thirty (30) days of the
            date PHS provides Licensee notice of the payment due.

9.   REPORTS ON PROGRESS, BENCHMARKS, SALES, AND PAYMENTS
     ----------------------------------------------------

     9.01   Prior to signing this Agreement, Licensee has provided to PHS a
            written commercialization plan ("Commercial Development Plan") 

                                       8
<PAGE>
 
            under which Licensee intends to bring the subject matter of the
            Licensed Patent Rights into commercial use. The Commercial
            Development Plan is hereby incorporated by reference into this
            Agreement. Based on this plan, performance benchmarks are determined
            as specified in Appendix E ("Benchmarks").

     9.02   Licensee shall provide written annual reports on its product
            development progress or efforts to commercialize under the
            Commercial Development Plan for each of the Licensed Fields of Use
            within sixty (60) days after December 31 of each calendar year.
            These progress reports shall include, but not be limited to:
            progress on research and development, status of applications for
            regulatory approvals, manufacturing, sublicensing, marketing, and
            sales during the preceding calendar year, as well as plans for the
            present calendar year.  If reported progress differs from that
            projected in the Commercial Development Plan and Benchmarks,
            Licensee shall explain the reasons for such differences.  Licensee
            may propose amendments in any such annual report to the Commercial
            Development Plan, acceptance of which by PHS may not unreasonably be
            denied.  Licensee agrees to provide any additional data reasonably
            required by PHS to evaluate Licensee's performance.  Licensee may
            amend the Benchmarks at any time upon written consent by PHS.  PHS
            shall not unreasonably withhold approval of any request of Licensee
            to extend the time periods of this schedule if such request is
            supported by a reasonable showing by Licensee of diligence in its
            performance under the Commercial Development Plan and toward
            bringing the Licensed Products to the point of practical application
            as defined in 37 CFR 404.3(d).  Licensee shall amend the Commercial
            Development Plan and Benchmarks at the request of PHS to address any
            Licensed Fields of Use not specifically addressed in the plan
            originally submitted.

     9.03   Licensee shall report to PHS the date of the First Commercial Sale
            in each country in the Licensed Territory within thirty (30) days of
            such occurrence.

     9.04   Licensee shall submit to PHS within sixty (60) days after each
            calendar half-year ending June 30 and December 31 a royalty report
            setting forth for the preceding half-year period the amount of the
            Licensed Products sold or Licensed Processes practiced by or on
            behalf of Licensee in each country within the Licensed Territory,
            the 

                                       9
<PAGE>
 
            Net Sales, and the amount of royalty accordingly due.  With each
            such royalty report, Licensee shall submit payment of the earned
            royalties due.  If no earned royalties are due to PHS for any
            reporting period, the written report shall so state.  The royalty
            report shall be certified as correct by an authorized officer of
            Licensee and shall include a detailed listing of all deductions made
            under Paragraph 2.05 to determine Net Sales made under Article 6 to
            determine royalties due.

     9.05   Licensee agrees to forward semi-annually to PHS a copy of such
            reports received by Licensee from its sublicensees during the
            preceding half-year period as shall be pertinent to a royalty
            accounting to PHS by Licensee for activities under the sublicense.

     9.06   Royalties due under Article 6 shall be paid in U.S. dollars.  For
            conversion of foreign currency to U.S. dollars, the conversion rate
            shall be the rate quoted in The Wall Street Journal on the day that
            the payment is due.  All checks and bank drafts shall be drawn on
            United States banks and shall be payable to NIH/Patent Licensing at
            the address shown on the Signature Page below.  Any loss of
            exchange, value, taxes, or other expenses incurred in the transfer
            or conversion to U.S. dollars shall be paid entirely by Licensee.
            All royalty payments due under this Agreement shall be mailed to the
            following address:  NIH, P.O. Box 360120, Pittsburgh, Pennsylvania
            15251-6120.  The royalty report required by paragraph 9.04 of this
            Agreement shall accompany each such payment and a copy of such
            report shall also be mailed to PHS at its address for notices
            indicated on the Signature Page of this Agreement.

     9.07   Late charges will be applied to any overdue payments as required by
            the U.S. Department of Treasury in the Treasury Fiscal Requirements
            Manual, Section 8025.40.  The payment of such late charges shall not
            prevent PHS from exercising any other rights it may have as a
            consequence of the lateness of any payment.

     9.08   All plans and reports required by this Article 9 and marked
            "confidential" by Licensee shall be treated by PHS as commercial and
            financial information obtained from a person and as privileged and
            confidential and, to the extent permitted by law, shall not be
            subject to disclosure under the Freedom of Information Act, 5 U.S.C.
            (S) 552.

10.  PERFORMANCE
     -----------

     10.01  Licensee shall use its reasonable best efforts to introduce the
            Licensed Products into the commercial market or apply the Licensed
            Processes to commercial use as soon as practicable.  "Reasonable
            best efforts" for the purpose of this provision shall include, but
            not be limited to, adherence to the Commercial Development Plan and
            performance of the Benchmarks.  The efforts of a sublicensee shall
            be considered the efforts of Licensee.

     10.02  Upon the First Commercial Sale, until the expiration of this
            Agreement, Licensee shall use its reasonable best efforts to keep
            Licensed Products and Licensed Processes reasonably accessible to
            the public.

11.  INFRINGEMENT AND PATENT ENFORCEMENT
     -----------------------------------

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

     11.02  Pursuant to this Agreement and the provisions of Chapter 29 of Title
            35, United States Code, Licensee may a) bring suit in its own name,
            at its own expense, and on its own behalf for infringement of
            presumably valid claims in the Licensed Patent Rights; b) in any
            such suit, enjoin infringement and collect for its use, damages,
            profits, and awards of whatever nature recoverable for such
            infringement; and c) settle any claim or suit for infringement of
            the Licensed Patent Rights-provided, however, that PHS and
            appropriate Government authorities shall have the first right to
            take such actions and shall have a continuing right to intervene in
            such suit.  Licensee shall take no action to compel the Government
            either to initiate or to join in any such suit for patent
            infringement.  Licensee may request the Government to initiate or
            joining any such suit if necessary to avoid dismissal of the suit.
            Should the Government be made a party to any such suit, Licensee
            shall reimburse the Government for any costs, expenses, or fees
            which the Government incurs as a result of such motion or other
            action, including any and all costs incurred by the Government in
            opposing any such motion or other action.  Upon Licensee's payment
            of all costs incurred by the Government as a result of Licensee's
            joinder motion or other action, these actions by 

                                      11
<PAGE>
 
            Licensee will not be considered a default in the performance of any
            material obligation under this Agreement. In all cases, Licensee
            agrees to keep PHS reasonably apprised of the status and progress of
            any litigation. Before Licensee commences an infringement action,
            Licensee shall notify PHS and give careful consideration to the
            views of PHS and to any potential effects of the litigation on the
            public health in deciding whether to bring suit.

     11.03  In any infringement action commenced under Paragraph 11.02, the
            expenses including costs, fees, attorney fees, and disbursements,
            shall be paid by Licensee.  Up to fifty percent (50%) of such
            expenses may be credited against the royalties payable to PHS under
            Paragraph 6.03 under the Licensed Patent Rights in the country in
            which such a suit is filed.  In the event that fifty percent (50%)
            of such expenses exceed the amount of royalties payable by Licensee
            in any calendar year, the expenses in excess may be carried over as
            a credit on the same basis into succeeding calendar years.  A credit
            against litigation expenses, however, may not reduce the royalties
            due in any calendar year to less than the minimum annual royalty.
            Any recovery made by Licensee, through court judgment or settlement,
            first shall be applied to reimburse PHS for royalties withheld as a
            credit against litigation expenses and then to reimburse Licensee
            for its litigation expense.  Any remaining recoveries shall be
            shared equally by Licensee and PHS.

     11.04  PHS shall cooperate fully with Licensee in connection with an
            infringement action initiated under Paragraph 11.02.  PHS agrees
            promptly to provide access to all necessary documents and to render
            reasonable assistance in response to a request by Licensee.

     11.05  In the event that a declaratory judgment action alleging invalidity
            or non-infringement of any of the Licensed Patent Rights shall be
            brought against Licensee or raised by way of counterclaim or
            affirmative defense in an infringement suit brought by Licensee
            under Paragraph 11.02, pursuant to this Agreement and the provisions
            of Chapter 29 of Title 35, United States Code or other statutes,
            Licensee may a) defend the suit in its own name, at its own expense,
            and on its own behalf for presumably valid claims in the Licensed
            Patent Rights; b) in any such suit, ultimately to enjoin
            infringement and to collect for its use, damages, profits, and
            awards of whatever nature recoverable for such infringement; and c)
            settle 

                                      12
<PAGE>
 
            any claim or suit for declaratory judgment involving the Licensed
            Patent Rights-provided, however, that PHS and appropriate Government
            authorities shall have the first right to take such actions and
            shall have a continuing right to intervene in such suit. Licensee
            shall take no action to compel the Government either to initiate or
            to join in any such declaratory judgment action. Licensee may
            request the Government to initiate or joining any such suit if
            necessary to avoid dismissal of the suit. Should the Government be
            made a party to any such suit by motion or any other action of
            Licensee, Licensee shall reimburse the Government for any costs,
            expenses, or fees which the Government incurs as a result of such
            motion or other action. Upon Licensee's payment of all costs
            incurred by the Government as a result of Licensee's joinder motion
            or other action, these actions by Licensee will not be considered a
            default in the performance of any material obligation under this
            Agreement. If Licensee elects not to defend against such declaratory
            judgment action, PHS, at its option, may do so at its own expense.
            In all cases, Licensee agrees to keep PHS reasonably apprised of the
            status and progress of any litigation. Before Licensee commences an
            infringement action, Licensee shall notify PHS and give careful
            consideration to the views of PHS and to any potential effects of
            the litigation on the public health in deciding whether to bring
            suit.

12.  NEGATION OF WARRANTIES AND INDEMNIFICATION
     ------------------------------------------

     12.01  PHS offers no warranties other than those specified in Article 1.

     12.02  PHS does not warrant the validity of the Licensed Patent Rights and
            makes no representations whatsoever with regard to the scope of the
            Licensed Patent Rights, or that the Licensed Patent Rights may be
            exploited without infringing other patents or other intellectual
            property rights of third parties.

     12.03  PHS MAKES NO WARRANTIES, EXPRESSED OR IMPLIED, OF MERCHANTABILITY OR
            FITNESS FOR A PARTICULAR PURPOSE OF ANY SUBJECT MATTER DEFINED BY
            THE CLAIMS OF THE LICENSED PATENT RIGHTS.

     12.04  PHS does not represent that it will commence legal actions against
            third parties infringing the Licensed Patent Rights.

                                      13
<PAGE>
 
     12.05  Licensee shall indemnify and hold PHS, its employees, students,
            fellows, agents, and consultants harmless from and against all
            liability, demands, damages, expenses, and losses, including but not
            limited to death, personal injury, illness, or property damage in
            connection with or arising out of a) the use by or on behalf of
            Licensee, its sublicensees, directors, employees, or third parties
            of any Licensed Patent Rights, or b) the design, manufacture,
            distribution, or use of any Licensed Products, Licensed Processes or
            materials, or other products or processes developed in connection
            with or arising out of the Licensed Patent Rights.  Licensee agrees
            to maintain a liability insurance program consistent with sound
            business practice.

13.  TERM, TERMINATION, AND MODIFICATION OF RIGHTS
     ---------------------------------------------

     13.01  This Agreement is effective when signed by all parties and shall
            extend to the expiration of the last to expire of the Licensed
            Patent Rights unless sooner terminated as provided in this Article
            13.

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

     13.03  At least thirty (30) days prior to filing a petition in bankruptcy,
            Licensee must inform PHS in writing of its intention to file the
            petition in bankruptcy or of a third party's intention to file an
            involuntary petition in bankruptcy.

     13.04  In the event that Licensee becomes insolvent, files a petition in
            bankruptcy, has such a petition filed against it, determines to file
            a petition in bankruptcy, or receives notice of a third party's
            intention to file an involuntary petition in bankruptcy, Licensee
            shall immediately notify PHS in writing.  Furthermore, PHS shall
            have the right to terminate this Agreement by giving Licensee
            written notice.  Termination of this Agreement is effective upon
            Licensee's receipt of the written notice.

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

                                      14
<PAGE>
 
     13.06  PHS shall specifically have the right to terminate or modify, at its
            option, this Agreement, if PHS determines that the Licensee:  1) is
            not executing the Commercial Development Plan submitted with its
            request for a license and the Licensee cannot otherwise demonstrate
            to PHS's satisfaction that the Licensee has taken, or can be
            expected to take within a reasonable time, effective steps to
            achieve practical application of the Licensed Products or Licensed
            Processes; 2) has not achieved the Benchmarks as may be modified
            under Paragraph 9.02; 3) has willfully made a false statement of, or
            willfully omitted, a material fact in the license application or in
            any report required by the license agreement; 4) has committed a
            substantial breach of a covenant or agreement contained in the
            license; 5) is not keeping Licensed Products or Licensed Processes
            reasonably available to the public after commercial use commences;
            6) cannot reasonably satisfy unmet health and safety needs; or 7)
            cannot reasonably justify a failure to comply with the domestic
            production requirement of Paragraph 5.01 unless waived.  In making
            this determination, PHS will take into account the normal course of
            such commercial development programs conducted with sound and
            reasonable business practices and judgment and the annual reports
            submitted by Licensee under Paragraph 9.02.  Prior to invoking this
            right, PHS shall give written notice to Licensee providing Licensee
            specific notice of, and a ninety (90) day opportunity to respond to,
            PHS's concerns as to the previous items 1) to 7).  If Licensee fails
            to alleviate PHS's concerns as to the previous items 1) to 7) or
            fails to initiate corrective action to PHS's satisfaction, PHS may
            terminate this Agreement.

     13.07  When the public health and safety so require, and after written
            notice to Licensee providing Licensee a sixty (60) day opportunity
            to respond, PHS shall have the right to require Licensee to grant
            sublicenses to responsible applicants, on reasonable terms, in any
            Licensed Fields of Use under the Licensed Patent Rights, unless
            Licensee can reasonably demonstrate that the granting of the
            sublicense would not materially increase the availability to the
            public of the subject matter of the Licensed Patent Rights.  PHS
            will not require the granting of a sublicense unless the responsible
            applicant has first negotiated in good faith with Licensee.

     13.08  PHS reserves the right according to 35 U.S.C. (S) 209(f)(4) to
            terminate or modify this Agreement if it is determined that such

                                      15
<PAGE>
 
            action is necessary to meet requirements for public use specified by
            Federal regulations issued after the date of the license and such
            requirements are not reasonably satisfied by Licensee.

     13.09  Within thirty (30) days of receipt of written notice of PHS's
            unilateral decision to modify or terminate this Agreement, Licensee
            may, consistent with the provisions of 37 CFR (S) 404.11, appeal the
            decision by written submission to the Director of NIH or designee.
            The decision of the NIH Director or designee shall be the final
            agency decision.  Licensee may thereafter exercise any and all
            administrative or judicial remedies that may be available.

     13.10  Within ninety (90) days of termination of this Agreement under this
            Article 13 or expiration under Paragraph 3.02, a final report shall
            be submitted by Licensee.  Any royalty payments, including those
            related to patent expense, due to PHS shall become immediately due
            and payable upon termination or expiration.  If terminated under
            this Article 13, sublicensees may elect to convert their sublicenses
            to direct licenses with PHS pursuant to Paragraph 4.03.

14.  GENERAL PROVISIONS
     ------------------

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

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

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

                                      16
<PAGE>
 
     14.04  If either Party desires a modification to this Agreement, the
            Parties shall, upon reasonable notice of the proposed modification
            by the Party desiring the change, confer in good faith to determine
            the desirability of such modification.  No modification will be
            effective until a written amendment is signed by the signatories to
            this Agreement or their designees.

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

     14.06  All notices required or permitted by this Agreement shall be given
            by prepaid, first class, registered or certified mail properly
            addressed to the other Party at the address designated on the
            following Signature Page, or to such other address as may be
            designated in writing by such other Party, and shall be effective as
            of the date of the postmark of such notice.

     14.07  This Agreement shall not be assigned by Licensee except a) with the
            prior written consent of PHS, such consent to be reasonably given;
            or b) as part of a sale or transfer of substantially the entire
            business of Licensee relating to operations which concern this
            Agreement.  Licensee shall notify PHS within ten (10) days of any
            assignment of this Agreement by Licensee.

     14.08  Licensee agrees in its use of any PHS-supplied materials to comply
            with all applicable statutes, regulations, and guidelines, including
            Public Health Service and National Institutes of Health regulations
            and guidelines.  Licensee agrees not to use the materials for
            research involving human subjects or clinical trials in the United
            States without complying with 21 CFR Part 50 and 45 CFR Part 46.
            Licensee agrees not to use the materials for research involving
            human subjects or clinical trials outside of the United States
            without notifying PHS, in writing, of such research or trials and
            complying with the applicable regulations of the appropriate
            national control authorities.  Written notification to PHS of
            research involving human subjects or clinical trials outside of the
            United States shall be given no later than sixty (60) days prior to
            commencement of such research or trials.

     14.09  Licensee acknowledges that it is subject to and agrees to abide by
            the United States laws and regulations (including the Export

                                      17
<PAGE>
 
            Administration Act of 1979 and Arms Export Control Act) controlling
            the export of technical data, computer software, laboratory
            prototypes, biological material, and other commodities.  The
            transfer of such items may require a license from the cognizant
            agency of the U.S. Government or written assurances by Licensee that
            it shall not export such items to certain foreign countries without
            prior approval of such agency.  PHS neither represents that a
            license is or is not required or that, if required, it shall be
            issued.

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

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

     14.12  The Parties agree to attempt to settle amicably any controversy or
            claim arising under this Agreement or a breach of this Agreement,
            except for appeals of modification or termination decisions provided
            for in Article 13.  Licensee agrees first to appeal any such
            unsettled claims or controversies to the Director of NIH, or
            designee, whose decision shall be considered the final agency
            decision.  Thereafter, Licensee may exercise any administrative or
            judicial remedies that may be available.

     14.13  Nothing relating to the grant of a license, nor the grant itself,
            shall be construed to confer upon any person any immunity from or
            defenses under the antitrust laws or from a charge of patent misuse,
            and the acquisition and use of rights pursuant to 37 CFR Part 404
            shall not be immunized from the operation of state or Federal law by
            reason of the source of the grant.

                           --------------------------

PHS and Licensee agree to the following modifications to the Articles and
Paragraphs of this Agreement:

ARTICLE FIVE

     5.03 (revised)  Licensee acknowledges that PHS may enter into future
Cooperative Research and Development Agreements (CRADAs) under the Federal
Technology Transfer Act of 1986 that relate to the subject matter of this
Agreement.  Licensee agrees not to unreasonably deny requests for sublicense or
cross license rights from such future collaborators with PHS when acquiring such
derivative rights is necessary in order to make a CRADA project feasible.
Licensee may request an opportunity to join as a party to the proposed CRADA.
Notwithstanding the foregoing, the grant of such derivative rights to a
prospective PHS collaborator by Licensee shall include the right to sell or have
sold the inventions defined by the Licensed Patent Rights in Licensed Fields of
Use only at the option of Licensee.

     5.05 (revised)  In addition to the reserved license of Paragraph 5.01
above, PHS reserves the right to grant nonexclusive licenses to make and to use,
but not to sell or have sold, the inventions defined by the Licensed Patent
Rights for purposes of research involving the inventions themselves, and not for
purposes of commercial manufacture or in lieu of purchase if the inventions are
available as commercial products for research purposes.  The purpose of this
research license is to encourage basic research, whether conducted at an
academic or corporate facility.  In order to safeguard the Licensed Patent
Rights, however, PHS shall consult with Licensee before granting to commercial
entities a research license or providing to them research samples of the
materials claimed in the Licensed Patent Rights.  In the event that Licensee can
provide convincing written evidence to PHS that a commercial entity that has
been granted a research license to Licensed Patent Rights is developing the
inventions for commercial manufacture or in lieu of purchase if the inventions
are available as commercial products, then Licensee can request that PHS
terminate its research license with such commercial entities, such request not
to be unreasonably denied.

                              U.S.P.A. 07/891,962

BACKGROUND

Cystic fibrosis (CF) is an autosomal recessive disease that afflicts 30,000
people in the United States and 60,000 worldwide.  The hallmarks of the disease
include thick, dehydrated airway mucus, chronic Pseudomonas lung infection,
pancreatic insufficiency, bile duct obstruction, infertility in males, reduced
fertility in females, intestinal obstruction, nasal polyp formation and chronic
sinusitis.  CF is caused by a defect in a protein called CFTR, found in
epithelial cells.

Approximately 90% of the mortality in CF patients is related to pulmonary
disease, caused by Pseudomanas infection and airway inflammation.  It is
believed that the pathology associated with CF may begin very early in life.
Thus, treating the patient very early in life before significant lung disease
occurs may be crucial.  Currently, the average life span of a CF patient is 29.

Recently, Genentech's DNase received a unanimous recommendation for approval by
an FDA advisory committee.  DNase is a useful product for the treatment of the
effects of CF, but does not address the causes of this disease.

Several gene therapy companies have developed adenovirus vector systems to
deliver the CFTR gene into the lungs of CF patients.  The single ongoing
clinical trial with an adenovirus delivery system, however, has yielded toxicity
problems relating to lung tissue inflammation caused by the vector.  These
results may serve to confirm preclinical animal studies conducted previously
with adenovirus-CFTR vectors where serious lung inflammation was also observed.

In addition to this toxicity concern, adenovirus is unable to sustain expression
of the CFTR gene in vivo beyond a few weeks.  Liposomes, which are in
preclinical development as delivery vehicles for the CFTR gene, have a similar
limitation.

TGC APPROACH

Adeno-associated virus (AAV) is a non-pathogenic human isolate which integrates
stably and with high efficiency into the genome of respiratory epithelial cells.
This type of vector may be used for stable correction of the gene defect early
in life, prior to onset of irreversible lung disease.

                                      29

TGC will initially deliver the Licensed Product vector directly into lungs of
patients via a bronchoscope.  An aerosol delivery system may be developed for
the vector if treatment is required more than two or three times per year.

Prior to initiation of clinical trials, TGC will be required to develop a
manufacturing process for the Licensed Product.  It is expected that this will
be completed by the end of 1994.  In parallel with this effort, the company will
initiate toxicology studies in large animals at Johns Hopkins University.  The
project is expected to be completed by the first quarter of 1995.  An
Investigational New Drug Application is scheduled to be filed by the end of
1995, with Phase I clinical studies slated to begin by the first quarter of
1996.

Phase I clinical studies for the Licensed Product will be conducted at Johns
Hopkins University under the director of Dr. Terence Flotte.  Dr. Flotte
recently completed studies at Johns Hopkins that demonstrated that CFTR
expression could be sustained for up to six months in the lungs of rabbits
receiving direct in vivo delivery of the Licensed Product.

The sequence of clinical trials needed to move the Licensed Product into PLA
filing position differs substantially from standard clinical trial design.  The
first Phase I trial will be designed to evaluate toxicity in adult CF patients
following delivery to a single lung lobe.  Subsequent Phase Ib or Phase II
studies are expected to be initiated by early 1998, and will be designed to
evaluate, from a safety and efficacy standpoint, bilateral whole lung delivery
in adults, repeated delivery of vector, as well as delivery to neonatal and
pediatric populations.  Phase III or Phase II/III clinical studies are expected
to begin by the first quarter of 2001, and will be designed on the basis of the
results from the Phase Ib or Phase II trials, as well as from additional pre-
clinical studies that may be conducted in parallel with the clinical trials.
Among the factors that will dictate how the Phase III (or II/III) trials are
designed are those following:

     .    Whether differential toxicity and/or efficacy profiles are observed
          between the pediatric and adult populations enrolled in the trial

     .    Whether adult patients in the trial derived significant efficacy from
          the therapy in the setting of chronic inflammation and scarring.

     .    Whether repeated delivery or non-bronchoscopic delivery was necessary
          for long-term efficacy of the vector.

Given the uncertainty regarding the design of the Phase III or Phase II/III
trials, it is difficult at this stage to predict when a Product Licensing
Application will be filed for the Licensed Product.

            others not employed by your institution and you will make good faith
            efforts to do so thirty (30) days prior to such written (or oral)
            disclosure;

     (vi)   that you and your institution shall bear all risk to you and/or any
            others resulting from any use, directly or indirectly, to which you
            put the Materials or any other material that could not have been
            made by for these Materials;

     (vii)  that you shall not sell or otherwise transfer to any other party the
            Materials, method(s) of using the Materials or any other material
            that could not have been made but for the Materials, whether with or
            without consideration, for any purpose or use;

     (viii) that you shall not, directly or indirectly, use the Materials for
            commercial purposes;

     (ix)   that you and your institution shall not obtain, and shall not
            attempt to obtain patent coverage on the Materials without the
            express written consent of MCO; and before seeking patent
            prosecution for the use of the Materials or any other materials that
            could not have been made but for the Materials, your institution
            will notify MCO so that MCO can assert any claims to legal
            inventorship it or its employees might have. In consideration of
            MCO's providing of the Material, your institution, to the extent it
            is able to do so under its policies and obligations to sponsors of
            your research, hereby grants to MCO a ninety (90) day option to
            negotiate a commercial license under any such patent application and
            your institution agrees to negotiate the license terms in good faith
            taking into account the respective parties' contributions and
            relevant industry and university standards for similar rights. Such
            option shall be exercised by MCO's agreement to support the filing
            of a U.S. patent application;

     (x)    except where precluded by Federal law and to the extent allowed by
            State law, you and your institution agree to defend, indemnify, and
            hold harmless MCO, its trustees, officers, employees, and agents
            from any

                                      16

            loss, claim, damage, or liability, of any kind whatsoever, which may
            arise from you or your institution's use, storage, or disposal of
            the Materials or any other material that could not have been made
            but for the Materials, except to the extent such arise due to the
            gross negligence of MCO;

     (xi)   that you provide us with your Federal Express account number so that
            we may ship the Materials to you.

     You understand that no other right or license to these Materials or any
other materials that could not have been made but for these Materials or to
their use is granted or implied as a result of our transmission of these
Materials to you.

     The Materials are to be used with caution and prudence in any experimental
work, since all of their characteristics are not known.  Moreover, they are not
to be used for testing in or treatment of humans.

     This Agreement shall be construed, interpreted, and applied in accordance
with the laws of the State of Ohio.

     This Agreement embodies the entire understanding between MCO and
(investigator institution) and supersedes all previous communications,
representations or understandings, either oral or written, between the parties
relating to transfer of these Materials.

     If you agree to accept these Materials under the above conditions, please
sign the enclosed duplicate copy of this letter, have it signed by an authorized
representative of your institution, and return one original to me.  Upon receipt
of that confirmation, the Materials will be forwarded to you.

                              THERAPEUTIC LICENSE

This is an Agreement, effective as of the 28th day of March, 1994 (the
"Effective Date"), entered into by Targeted Genetics Corporation, a corporation
incorporated in the State of Washington, with offices located at 1100 Olive Way,
Suite #100, Seattle, Washington 98101 ("LICENSEE"), the Regents of the
University of Michigan, a constitutional corporation of the State of Michigan
("MICHIGAN"), and HSC Research and Development Limited Partnership, a
partnership organized and subsisting under the laws of the Province of Ontario,
Canada ("RDLP").  LICENSEE, MICHIGAN and RDLP agree as follows:

1.   BACKGROUND.
     ---------- 

     1.1  Michigan and the Research Institute of the Hospital for Sick Children
of Toronto, Ontario, Canada ("HSC") have conducted research relating to cystic
fibrosis. As a result of that research, MICHIGAN and RDLP have developed rights
in the "Licensed Patents" defined below.

     1.2  LICENSEE desires to obtain, and MICHIGAN and RDLP, consistent with
their missions of education and research, desire to grant a license of the
Licensed Patents on the terms and conditions listed below.

2.   DEFINITIONS.
     ----------- 

     2.1  "TECHNOLOGY", as used in this Agreement, shall mean the information,
manufacturing techniques, data, designs or concepts developed by MICHIGAN and
HSC, covering the gene for cystic fibrosis and uses thereof as encompassed by
U.S. Patent Application No. 401,609 entitled "Cystic Fibrosis Gene."

     2.2  "Parties", in singular or plural usage as required by the context,
shall mean LICENSEE, MICHIGAN and/or RDLP.

     2.3  "Affiliate(s)" shall mean any individual, corporation, partnership,
proprietorship or other entity controlled by, controlling, or under common
control with LICENSEE through equity ownership, ability to elect directors, or
by virtue of a majority of overlapping directors, and shall include any
individual, corporation, partnership, proprietorship or other entity directly or
indirectly owning, owned by or under common ownership with LICENSEE to the
extent of 
<PAGE>
 
thirty percent (30%) or more of the voting shares, including shares owned
beneficially by such party.

     2.4  "Licensed Patent(s)" shall mean U.S. Patent Application No. 401,609
entitled "Cystic Fibrosis Gene." and all foreign equivalent patent applications
and Patent Cooperation Treaty filings, and all patents issuing therefrom in
which MICHIGAN and/or RDLP has or acquires a property interest (currently
including the applications listed in the Appendix attached to this Agreement).
"Licensed Patent(s)" shall also include any divisional, continuation (excluding
continuations-in-part), reissue, reexamination or extension of the above-
described patent applications and resulting patents, along with any extended or
restored term, and any confirmation patent, registration patent, or patent of
addition.

     2.5  "Valid Claim(s)" means any claim(s) in an unexpired patent or pending
in a patent application included within the Licensed Patents which has not been
held unenforceable, unpatentable, or invalid by a decision of a court or other
governmental agency of competent jurisdiction, unappealable or unappealed within
the time allowed for appeal, and which has not been admitted to be invalid or
unenforceable through reissue or disclaimer. If in any country there should be
two or more such decisions conflicting with respect to the validity of the same
claim, the decision of the higher or highest tribunal shall thereafter control;
however, should the tribunals be of equal rank, then the decision or decisions
upholding the claim shall prevail when the conflicting decisions are equal in
number, and the majority of decisions shall prevail when the conflicting
decisions are unequal in number.

     2.6  "Product(s)" shall mean any product(s) whose manufacture, use or sale
in any country would, but for this Agreement, comprise an infringement,
including contributory infringement, of one or more Valid Claims.

     2.7  "Field of Use" shall refer to the field for which Products may be
designed, manufactured, used and/or marketed under this Agreement, and shall
mean solely Products to be used for the therapeutic treatment or prophylaxis of
the disease cystic fibrosis.

     2.8  "Net Sales" shall mean the sum, over the term of this Agreement, of
all amounts received and all other consideration received (or, when in a form
other than cash or its equivalent, the fair market value thereof when received)
by LICENSEE and its Affiliates from persons or entities due to or by reason of
the sale or other distribution of Products, or the use of Products, including
any use by LICENSEE and Affiliates in the performance of services for their
customers; 

                                       2
<PAGE>
 
less the following deductions and offsets, but only to the extent such sums are
otherwise included in the computation of Net Sales, or are paid by LICENSEE and
not otherwise reimbursed: refunds, rebates, replacements or credits actually
allowed and taken by purchasers for return of Products; customary trade,
quantity and cash discounts actually allowed and taken; excise, value-added, and
sales taxes actually paid by LICENSEE for Products; and shipping and handling
charges actually paid by LICENSEE for Products.

     2.9  "Royalty Quarter(s)" shall mean the three-month periods ending on the
last day of March, June, September and December of each year.

     2.10  "Territory" means all countries of the world.

     2.11  "First Therapeutic Sale" shall mean the first sale of any Product
(including any sale of a service using a Product in the Field of Use) by
LICENSEE or an Affiliate, other than for use in clinical trials being conducted
to obtain FDA or other governmental approvals to market Products.

3.   GRANT OF LICENSE.
     ---------------- 

     3.1  MICHIGAN and RDLP hereby grant to LICENSEE a non-exclusive license
under the Licensed Patents to make, have made, use (including use in the
performance of services for its customers), market and sell, in the Territory,
Products designed and marketed solely for use in the Field of Use.

     3.2  MICHIGAN and RDLP reserve the right to license and use all aspects of
the TECHNOLOGY and the Licensed Patents for any use or purpose, including the
right to develop and produce Products.

     3.3  The license granted to LICENSEE herein shall be without the right to
sublicense, except that LICENSEE may sublicense Affiliate(s) who agree to be and
are bound in writing to the terms and conditions of this Agreement to the same
extent as LICENSEE.  LICENSEE agrees to strictly monitor and enforce compliance
with the terms and conditions of this Agreement by all Affiliate sublicensees.

     3.4  If through exercise of its license under Paragraph 3.1 LICENSEE learns
of therapeutic or prophylactic fields of use for Products outside of the Field
of Use, then MICHIGAN and RDLP shall, upon LICENSEE's request, discuss in good
faith whether a separate agreement may be negotiated to provide LICENSEE the
rights necessary to develop and distribute Products designed and marketed for
such fields of use.

                                       3
<PAGE>
 
4.   CONSIDERATION.
     ------------- 

     4.1  LICENSEE shall pay to MICHIGAN a one-time license issue fee of U.S.
$40,000.00, forthwith following the Effective Date.  Notwithstanding any other
terms of this Agreement, this Agreement and the license granted hereunder shall
not become effective until such issue fee is received by MICHIGAN.

     4.2  LICENSEE shall also pay MICHIGAN, with respect to each Royalty
Quarter, a royalty [     *     ] of the Net Sales of LICENSEE and Affiliates.

     4.3  The obligation to pay MICHIGAN a royalty under this Article 4 is
imposed only once with respect to the same unit of Product regardless of the
number of Valid Claims or Licensed Patents covering the same; however, for
purposes of determination of payments due hereunder, whenever the term "Product"
may apply to a property during various stages of manufacture, use or sale, Net
Sales, as otherwise defined, shall be derived from the sale, distribution or use
of such Product by LICENSEE or Affiliates at the stage of its highest invoiced
value to unrelated third parties.

     4.4  LICENSEE shall pay to MICHIGAN an annual license maintenance fee.
This annual fee shall accrue in the Royalty Quarter ending in March of the years
specified below, and shall be due and payable and included with the report for
that quarter.

     If LICENSEE defaults in the payment of any annual license maintenance fee,
and fails to remedy that default within thirty (30) days after written notice of
it by MICHIGAN, then this Agreement and the license rights conveyed herein shall
terminate.

     The annual license maintenance fees shall be as follows:

     (1)  In 1994 and 1995:  [    *    ];

     (2)  In 1996, 1997 and 1998:  [    *    ];

     (3) in 1999, and in each year thereafter during the term of this Agreement
up to and including the year in which LICENSEE first obtains FDA approval or
other governmental approval to distribute or use Products in the Field of Use:
[    *    ];

[*] Confidential Treatment Requested

                                       4
<PAGE>
 
Also, notwithstanding (1-3) above (and in place of the amounts therein listed,
when applicable):

     (4)  In the first calendar year following the year in which LICENSEE
obtains the approval described in (3) above, and in each year thereafter during
the term of this Agreement up to and including the year in which the First
Therapeutic Sale occurs: [     *     ];

     Also, notwithstanding (1-4) above (and in place of the amounts therein
listed, when applicable);

     (5)  In the first calendar year following the First Therapeutic Sale: 
[    *    ];

     (6) In the second year following the First Therapeutic Sale: [    *    ];

     (7) In the third year following the First Therapeutic Sale: [    *    ]; 
and

     (8) In the fourth year following the First Therapeutic Sale, and in each
year thereafter during the term of this Agreement; [    *    ].

     Each annual fee paid under (5-8) above may be credited by LICENSEE in full
against all earned royalties otherwise to be paid to MICHIGAN under Paragraph
4.2 for the calendar year in which the specific annual fee is paid.  The year
for which such credits against royalties may be taken includes the Royalty
Quarter in which the annual fee accrues and the next three Royalty Quarters.

     Each annual fee paid under (1-4) above may be credited by LICENSEE in full
against all earned royalties otherwise to be paid to MICHIGAN under Paragraph
4.2 after such annual fee is paid.

     4.5  If it is necessary for LICENSEE to take any license(s), in a given
country, under valid third party patents which would be infringed by the
practice of Licensed Patents in that country, then LICENSEE can deduct up to 
[    *    ] of the royalties otherwise due and payable in each Royalty Quarter 
under Paragraph 4.2 above for Net Sales in that country, until such time as 
LICENSEE has recovered an amount equal to [    *    ] of the royalty paid to 
such third parties; provided that in no event shall such deducted amounts be 
applied to reduce or require

[*] Confidential Treatment Requested

                                       5
<PAGE>
 
reimbursement of the annual fees required under Paragraph 4.4.  This Paragraph
is not intended to imply an obligation upon MICHIGAN or RDLP to reimburse
LICENSEE's above-described third-party royalties; the rights granted to LICENSEE
in this Paragraph shall not exceed the ability of the above-described mechanism
(i.e., a [    *    ] of royalties due upon Net Sales in the country in question)
to reimburse such expenses. LICENSEE shall make an accounting to MICHIGAN of all
such third-party royalties, and all resulting deductions from royalties
otherwise due and payable to MICHIGAN, as part of its reporting obligations
under Article 5 below.

5.   REPORTS.
     ------- 

     5.1  Within sixty (60) days after the close of (i) any Royalty Quarter in
which a fee under Paragraph 4.4 accrues, and (ii) each Royalty Quarter following
the First Therapeutic Sale during the term of this Agreement (including the
close of any Royalty Quarter immediately following any termination of this
Agreement), LICENSEE shall report to MICHIGAN all royalties accruing to MICHIGAN
during such Royalty Quarter.  Such quarterly reports shall indicate for each
Royalty Quarter the gross sales and Net Sales of Products by LICENSEE and
Affiliates, and any other revenues with respect to which payments are due, and
the amount of such payments, as well as the various calculations used to arrive
at said amounts, including the quantity, description (nomenclature and type
designation), country of manufacture and country of sale of Products.  In case
no payment is due for any such period, LICENSEE shall so report.

     5.2  LICENSEE covenants that it will promptly establish and consistently
employ a system of specific nomenclature and type designations for Products so
that various types can be identified and segregated, where necessary; LICENSEE
and Affiliates shall consistently employ such system when rendering invoices
thereon and henceforth agree to inform MICHIGAN, or its auditors, when requested
as to the details concerning such nomenclature system as well as to all
additions thereto and changes therein.

     5.3  LICENSEE shall keep, and shall require its Affiliates to keep, true
and accurate records and books of account containing data reasonably required

[*] Confidential Treatment Requested

                                       6
<PAGE>
 
for the computation and verification of payments to be made as provided by this
Agreement, which records and books shall be open for inspection upon reasonable
notice during business hours by an independent certified accountant selected by
MICHIGAN.  Said right of inspection will exist for six (6) years from the date
of origination of any such record, and this requirement and right of inspection
shall survive any termination of this Agreement.  The independent certified
accountant shall provide to MICHIGAN only such information from LICENSEE's books
and records as is necessary to verify the accuracy or degree of inaccuracy of
the payments made under this Agreement.  MICHIGAN shall be responsible for all
expenses of such inspection, except that if such inspection reveals an
underpayment of royalties to MICHIGAN in excess of ten percent (10%) for any
year, then said inspection shall be at LICENSEE's expense and such underpayment
shall become immediately due and payable to MICHIGAN.

     5.4  The reports provided for hereunder shall be certified by an authorized
representative of LICENSEE to be correct to the best of LICENSEE's knowledge and
information.

6.   TIMES AND CURRENCIES OF PAYMENTS.
     -------------------------------- 

     6.1  Payments accrued during each Royalty Quarter shall be due and payable
in Ann Arbor, Michigan on the date each quarterly report is due (as provided in
Paragraph 5.1), shall be included with such report and shall be paid in United
States dollars.  LICENSEE agrees to make all payments due hereunder to MICHIGAN
by check made payable to "The Regents of The University of Michigan," and sent
by prepaid, certified or registered mail, return receipt requested, to the
address for notices set forth in Article 19 herein.

     6.2  On all amounts outstanding and payable to MICHIGAN, interest shall
accrue from the date such amounts are due and payable at two percentage points
above the prime lending rate as established by the Chase Manhattan Bank N.A., in
New York City, New York, or at such lower rate as may be required by law.

     6.3  Where Net Sales are generated in foreign currency during any Royalty
Quarter, such foreign currency shall be converted into its equivalent in United
States dollars at the exchange rate of such currency as reported (or if
erroneously reported, as subsequently corrected) in the Wall Street Journal on
the last business day of that Royalty Quarter (or if not reported on that date,
as quoted by the Chase Manhattan Bank, N.A., in New York City, New York).

                                       7
<PAGE>
 
     6.4  Except as provided in the definition of Net Sales, all royalty
payments to MICHIGAN under this Agreement shall be without deduction for sales,
use, excise, personal property or other similar taxes or other duties imposed on
such payments by the government of any country or any political subdivision
thereof; and any and all such taxes or duties shall be assumed by and paid by
LICENSEE.

7.   COMMERCIALIZATION.
     ----------------- 

     7.1  It is understood that LICENSEE has the responsibility to do all that
is necessary for any governmental approvals to manufacture and/or sell Products.

     7.2  LICENSEE agrees to use reasonable efforts to develop Products, obtain
any government approvals necessary, and manufacture and sell Products at the
earliest possible date; and to effectively exploit, market and manufacture in
sufficient quantities to meet anticipated customer demand and to make the
benefits of the Products reasonably available to the public.

     7.3  Within fifteen (15) days of the First Therapeutic Sale, LICENSEE shall
report by written letter to MICHIGAN the date and general terms of that sale.

8.   PATENT APPLICATIONS AND MAINTENANCE.
     ----------------------------------- 

     8.1  MICHIGAN and RDLP shall control all aspects of filing, prosecuting,
and maintaining Licensed Patents, including foreign filings and Patent
Cooperation Treaty filings.  MICHIGAN and RDLP may in their sole discretion
decide to refrain from or to cease prosecuting or maintaining any of the
Licensed Patents, including any foreign filing or any Patent Cooperation Treaty
filing.

     8.2  MICHIGAN shall notify LICENSEE of the issuance of any Licensed Patent
and the Valid Claims included therein, and any lapse, revocation, surrender,
invalidation or abandonment of any Licensed Patent or Valid Claim.

9.   INFRINGEMENT.
     ------------ 

     9.1  If LICENSEE becomes aware of or reasonably suspects infringement of
Licensed Patents by third parties, LICENSEE agrees to promptly notify Michigan
of such alleged infringement.

                                       8
<PAGE>
 
     9.2  MICHIGAN and RDLP shall take such measures as are in their reasonable
discretion appropriate to stop or discourage substantial infringements of the
Licensed Patents.  On request by the LICENSEE, MICHIGAN and RDLP shall inform
LICENSEE of any measures being taken in response to any particular event or
allegation of infringement.

     If MICHIGAN and RDLP fail to commence reasonable efforts to stop or
discourage a continuing substantial infringement of the Licensed Patents in any
country within six (6) months of MICHIGAN's receipt of written notice by
LICENSEE of that infringement, then LICENSEE may, upon written notice to
MICHIGAN, withhold royalty payments accruing under this Agreement upon Net Sales
which are thereafter generated in the country in which the infringement is
occurring, instead placing such royalty payments in escrow with an escrow agent
satisfactory to MICHIGAN and LICENSEE.  If, within six (6) months of such notice
by LICENSEE, MICHIGAN or RDLP commences reasonable efforts to stop or discourage
the infringement, then LICENSEE's withheld royalties shall be released from
escrow and paid to MICHIGAN.  If MICHIGAN and RDLP fail to commence such
reasonable efforts, then the withheld payments shall be released and returned to
LICENSEE and further royalty payments by LICENSEE with respect to Net Sales
generated in the country in which the infringement is occurring shall be waived
by MICHIGAN until MICHIGAN or RDLP in good faith commences such reasonable
efforts, upon which date the waiver of royalties by MICHIGAN shall terminate and
royalties accruing upon LICENSEE's Net Sales generated in that country after
that date shall be due and payable as provided in this Agreement.

     An infringement shall not be deemed substantial under this paragraph unless
it can be demonstrated that it generates more than the equivalent of five
million U.S. Dollars (U.S. $5,000,000.00) in sales of infringing products for
use in the Field of Use, and that such sales comprise five percent or more (in
dollar volume) of the total sales market in the Field of Use in that country.

     Reasonable efforts to be made by MICHIGAN and RDLP to stop or discourage
infringements may include notices, attempts to properly license the infringer,
or legal proceedings to enjoin or claim damages from the infringement.  The
reasonable efforts to be made by MICHIGAN or RDLP shall not be deemed to include
the commencement or maintenance of any legal proceeding where the projected cost
of the proceeding exceeds either the royalties received by MICHIGAN and RDLP for
the practice of the Licensed Patents in the Field of Use in that country, or the
damages likely to be actually awarded and collected as a result of the
proceeding.

                          EXCLUSIVE LICENSE AGREEMENT

     This Agreement is entered into as of the 23rd day of March, 1994 by and
between the Fred Hutchinson Cancer Research Center, a Washington non-profit

produced at FHCRC should be used for the greatest possible public benefit and
believes that every reasonable incentive should be provided for the prompt
introduction of such ideas into public use, all in a manner consistent with the
public interest;

     Whereas TGC desires to obtain an exclusive worldwide license in order to
practice the above referenced invention covered by LICENSED PATENT RIGHTS in the
United States and in certain foreign countries, and to manufacture, use and sell
in the commercial market the products made in accordance therewith; and

     Whereas FHCRC is willing to grant such a license to TGC subject to the
terms and conditions of this Agreement.

                                                 TGC EXCLUSIVE LICENSE AGREEMENT
 
                               ARTICLE 2 - GRANT

     2.1  FHCRC hereby grants to TGC and TGC accepts, subject to the terms and
conditions hereof, an exclusive worldwide license, under LICENSED PATENT RIGHTS,
to make, to use, to sell the LICENSED PRODUCTS, and to practice the LICENSED
PROCESSES, for the Term permitted in Article 3 of this Agreement (the
"License").  The License granted to TGC by FHCRC hereunder is limited to those
fields of use relevant for the prophylaxis and treatment of human disease in the
methods described under LICENSED PATENT RIGHTS.  Any license in any other field
shall be the subject of a separate agreement and shall require TGC's submission
of evidence demonstrating its willingness and ability to develop and
commercialize the kinds of products or processes likely to be encompassed in
such other field.  Such license shall include the right to grant sublicenses,
subject to the provisions of Section 2.2 below.  In order to provide TGC with a
period of exclusivity, FHCRC agrees it will not grant licenses to others except
as permitted in Section 2.2 below.  TGC agrees during the period of exclusivity
of this license in the United States that any LICENSED PRODUCT produced for sale
in the United States will be manufactured substantially in the United States.

     2.2  The License is subject to the following policies, obligations and/or
conditions:

          (a)  FHCRC's Patents and Inventions Policy adopted September 30, 1983,
               Public Law 98-620 and FHCRC's obligations under agreements with
               other sponsors of research.  Any right granted in this Agreement
               greater than that permitted under Public Law 98-620 shall be
               subject to modification as may be required to conform to the
               provisions of the statute.

          (b)  For research purposes only and not for any commercial purpose,
               FHCRC shall have the right to make and to use the TECHNOLOGY.

          (c)  TGC shall use reasonable effort to introduce the LICENSED
               PRODUCTS into the commercial market as soon as practicable,
               consistent with sound and reasonable business practices and
               judgment, and thereafter endeavor to keep LICENSED PRODUCTS
               reasonably available to the public.

          (d)  FHCRC shall have the right to terminate or render this Agreement
               nonexclusive at any time after three (3) years from the date
               hereof if, in FHCRC's reasonable judgment, TGC:

                                                 TGC EXCLUSIVE LICENSE AGREEMENT
 
               (i)  has not put the licensed subject matter into commercial use
                    in the country or countries where licensed, directly or
                    through a sublicense, and is not keeping the licensed
                    subject matter reasonably available to the public, or

               (ii) is not demonstrably engaged in research, development,
                    manufacturing, marketing or licensing program, as
                    appropriate, directed toward these ends; or

               (iii)  has not expended at least three hundred thousand dollars
                    ($300,000) in the twelve (12) month period beginning (3)
                    years from the EFFECTIVE DATE, or in any (12) twelve month
                    period beginning anytime thereafter, on internal and
                    external personnel, their benefits, supplies and equipment
                    related to research and development of the LICENSED PRODUCTS

               In making this determination FHCRC shall take into account the
               normal course of such programs conducted with sound and
               reasonable business practices and judgment and shall take into
               account the reports provided hereunder by TGC.

          (e)  TGC shall not grant any sublicense without FHCRC's prior written
               consent.  All sublicenses granted by TGC hereunder shall include
               a requirement that the sublicensee use its best efforts to bring
               the subject matter of the sublicense into commercial use as
               quickly as is reasonably possible and shall expressly bind the
               sublicensee to meet TGC's obligations to FHCRC under this
               Agreement.  Copies of all sublicense agreements shall promptly be
               provided to FHCRC.

          (f)  In the event FHCRC becomes aware of third parties that wish to
               license the LICENSED PATENT RIGHTS in specific fields of use that
               would not result in direct or indirect competition to TGC, FHCRC
               shall notify TGC and TGC shall exercise one of the following
               options:

               (i)  commence active research and development of LICENSED
                    PRODUCTS under the LICENSED PATENT RIGHTS in that field of
                    use;

               (ii) grant a sublicense to said third parties to make, use and
                    sell LICENSED PRODUCTS under the LICENSED PATENT RIGHTS in
                    that field of use; or

               (iii) grant the right to FHCRC to directly license said third
                    parties to make, use and sell LICENSED PRODUCTS under the
                    LICENSED PATENT RIGHTS in that field of use.

     2.3  Notwithstanding the foregoing provisions of Article 2, TGC shall have
the right to assign the license granted under Article 2 to an AFFILIATE or to
any organization that acquires all or substantially all of TGC's business,
subject to the terms and conditions hereof.

     2.4  This Agreement shall have no effect upon any and all rights reserved
to the United States Government and others under Public Law 98-620.

                         ARTICLE 3 - TERM OF AGREEMENT

     3.1  This Agreement becomes effective as of the date first above written
(the "Effective Date"), and, subject to earlier termination as provided in
Article 9 shall remain in effect until the last to expire of the LICENSED PATENT
RIGHTS (the "Term").

                             ARTICLE 4 - ROYALTIES

     4.1   In consideration for the granting of the License, TGC shall pay to
FHCRC a non-refundable license fee ("License Fee") in the sum of [ * ] of such

     4.2  During the Term, TGC shall pay to FHCRC a royalty in the amount of
[ * ] of the NET SALES of all LICENSED PRODUCTS and all products using LICENSED
PROCESSES and all services utilizing LICENSED PRODUCTS or LICENSED PROCESSES
which are manufactured or used by TGC and its AFFILIATES or sublicensees in the
United States, and leased or sold by TGC and its AFFILIATES or sublicenses in
the United States, except, however, that the foregoing royalty rate may be
reduced by one half the amount of third party royalties payable on

licenses required to make, use or sell LICENSED PRODUCTS or to practice a
LICENSED PROCESS, but in no case shall the royalty rate be reduced to less than
[ * ] of NET SALES.

     4.3  During the Term, TGC shall pay to FHCRC a royalty in the amount of
[ * ] of the NET SALES of all LICENSED PRODUCTS and all products using LICENSED
PROCESSES and all services utilizing LICENSED PRODUCTS or LICENSED PROCESSES
which are manufactured or used by TGC and its AFFILIATES or sublicensees in the
United States, and leased or sold by TGC and its AFFILIATES or sublicenses
outside of the United States, except, however, that the foregoing royalty rate
may be reduced by one half the amount of third party royalties payable on
licenses required to make, use or sell LICENSED PRODUCTS or to practice a
LICENSED PROCESS, but in no case shall the royalty rate be reduced to less than
[ * ] of NET SALES.

     4.4  No multiple royalties shall be payable because any LICENSED PRODUCT
which TGC manufactures, uses, leases or sells is covered by multiple claims
under the LICENSED PATENT RIGHTS.

     4.5  TGC shall pay to FHCRC at least the following amounts in royalties in
the following contract years (the "Maintenance Royalties"):

          (i)  [ * ] upon the earlier of the issuance of the first patent
               included in the LICENSED PATENT RIGHTS or [ * ];

          (ii) [ * ] upon the earlier of approval to commence Phase 2 (as
               defined by 21 Code of Federal Regulations, Chapter 1) clinical
               trials for the first LICENSED PRODUCT or [ * ]; and

          (iii)  [ * ] upon approval of the New Drug Application ("NDA") or
               Product License Application ("PLA") (as defined by 21 Code of
               Federal Regulations, Chapter 1) for the first LICENSED PRODUCT or
               [ * ].

     4.6  If TGC transfers or otherwise sublicenses LICENSED PATENT RIGHTS to a
third party, for value other than NET SALES, TGC shall also pay FHCRC a
percentage of [ * ] of all proceeds including, but not limited to, licensing
fees, receivable by TGC in connection therewith ("Non-Royalty Fees").

Any such payment to FHCRC shall be made within thirty (30) days after receipt of
such proceeds by TGC.  Any such sale or transfer shall not affect TGC's
obligations to pay royalties under Sections 6.2 and 6.3 above.  In no event
shall Non-Royalty Fees include any payment or other value due to or received by
TGC from a third party as, for example, an upfront fee, research and development
payments, milestone payments, equity, or any equivalent of the foregoing, or of
any payment that is not explicitly due to or received by TGC in consideration
for a grant by TGC to a third party to make, have made, use and sell LICENSED
PRODUCTS, or practice LICENSED PROCESSES, under LICENSED PATENT RIGHTS.

     In the event that TGC transfers or otherwise sublicenses LICENSED PATENT
RIGHTS to a third party in combination with patents(s) and/or other rights(s) of
a third party(ies) and TGC is due and receives Non-Royalty Fees, then TGC shall
pay FHCRC an equitable portion of such Non-Royalty Fees as to be determined by
the good faith negotiations of TGC and FHCRC.

                ARTICLE 5 - REPORTING AND ROYALTY PAYMENT TERMS

     5.1  Upon or before execution of this Agreement, TGC shall provide to FHCRC
a written research and development plan pursuant to which TGC intends to bring
the subject matter of the License granted hereunder into commercial use,
including projections of sales and proposed marketing efforts.

     5.2  TGC shall report to FHCRC the date of first sale of LICENSED PRODUCTS
(or results of LICENSED PROCESSES) in each country within thirty (30) days of
occurrence.

     5.3  TGC shall provide written annual reports within sixty (60) days after
June 30 of each calendar year which shall include the following information:
reports of progress on research and development, regulatory approvals,
manufacturing, sublicensing, marketing and sales during the preceding twelve
(12) months as plans for the coming year.  If TGC's progress differs from that
anticipated in the plan provided to FHCRC under Section 5.1, TGC shall explain
the reasons for the difference and propose a modified plan for FHCRC's review
and approval.  TGC shall also provide any reasonable additional data FHCRC
requires to evaluate TGC's performance.

     5.4  Beginning after the first NET SALES, TGC shall submit to FHCRC within
sixty (60) days after June 30 and December 31 of each calendar year during the
Term, and upon the effective termination of this Agreement, reports for the
preceding six (6) month period identifying the amount of the LICENSED PRODUCTS
sold by TGC, its AFFILIATES and sublicensees in each country, the sales volume
and NET

SALES, and the amount of royalty due to FHCRC together with payment of such
royalty amount. Such report shall be certified as correct by an officer of TGC
and shall include a detailed listing of all deductions from NET SALES,
sublicensee income or from royalties as specified herein. If no royalties are
due to FHCRC for any reporting period, the written report shall so state. All
royalties due hereunder shall be payable in United States dollars. Conversion of
foreign currency to U.S. dollars shall be made at the conversion rate existing
in the United States on the date of royalty payments by TGC as quoted in the
Wall Street Journal for that day.

     5.5  All such reports shall be maintained in confidence by FHCRC, except as
required by law, including Public Law 98-620.

                           ARTICLE 6 - RECORD KEEPING

     6.1  TGC shall maintain complete and accurate books of account and records
showing all sales of LICENSED PRODUCTS and all NET SALES (broken down by gross
sales and allowable deductions) attributable to such sales.  For purposes of
verifying the accuracy of the royalties paid by TGC pursuant to this Agreement
or verifying performance of TGC of any other obligation to FHCRC hereunder, such
books and records shall be open to inspection and copying, during usual business
hours, by an independent certified public accountant or by employees of FHCRC.
Such accountant shall not disclose to FHCRC any information other than
information relating to accuracy of reports and calculations of amounts due to
FHCRC made under this Agreement.  In the event that any such inspection shows
any underreporting and underpayment by TGC in excess of five percent (5%) for
any twelve (12) month period, then TGC shall pay the cost of such examination.
Such books and records shall be maintained for at least two (2) full years after
the termination of this Agreement.

         ARTICLE 7 - DOMESTIC AND FOREIGN PATENT FILING AND MAINTENANCE

     7.1  TGC shall reimburse FHCRC for all reasonable expenses FHCRC has
incurred for the preparation, filing, prosecution and maintenance of LICENSED
PATENT RIGHTS and shall reimburse FHCRC for all such future expenses ("PATENT
EXPENSES").  With respect to PATENT EXPENSES incurred prior to the Effective
Date, TGC shall reimburse FHCRC for fifty percent (50%) of such expenses no
later than June 30, 1994, and shall reimburse FHCRC for fifty percent (50%) of
such expenses no later than June 30, 1995.  TGC shall reimburse FHCRC for all
PATENT EXPENSES incurred subsequent to the Effective Date as they are invoiced
by FHCRC.  FHCRC shall take responsibility for the preparation, filing,
prosecution and maintenance of any and all patent applications and patents
included

in LICENSED PATENT RIGHTS, provided however that FHCRC shall first consult with
TGC as to the preparation, filing, prosecution and maintenance of such patent
applications and patents and shall furnish to TGC copies of documents relevant
to any such preparation, filing, prosecution or maintenance. Notwithstanding the
foregoing, FHCRC may consent subsequent to the Effective Date for TGC to assume
such responsibilities with respect to the LICENSED PATENT RIGHTS.

     7.2  FHCRC and TGC shall cooperate fully and in good faith in the
preparation, filing, prosecution and maintenance of LICENSED PATENT RIGHTS and
of all patents and patent applications licensed to TGC hereunder, including the
execution of all papers and instruments so as to enable FHCRC to apply for, to
prosecute and to maintain patent applications and patents in FHCRC's name in any
country.  Each party shall provide to the other prompt notice as to all matters
which come to its attention and which may affect the preparation, filing,
prosecution or maintenance of any such patent applications or patents.

     7.3  If TGC elects not to pay the expenses of a patent application or
patent included within LICENSED PATENT RIGHTS, TGC shall notify FHCRC not less
than sixty (60) days prior to such action and shall thereby surrender its rights
under Article 2.1 of this Agreement with regard to such patent or patent
application.

                            ARTICLE 8 - INFRINGEMENT

     8.1  Each party agrees to notify the other promptly of any infringement of
the LICENSED PATENT RIGHTS of which such party becomes aware.  TGC shall have
the option to commence legal proceedings with respect to such infringement.
Before TGC commences legal proceedings (an "Action") with respect to any
infringement of such patents, TGC shall give careful consideration to the views
of FHCRC and to potential effects on the public interest in making its decision
whether or not to commence such an Action.

     8.2  If TGC elects to commence an Action as described above, TGC may
reduce, by up to fifty percent (50%), the royalty due to FHCRC earned under the
patent subject to suit by the amount of the expenses and costs of such Action,
including attorney fees.  In the event such expenses and costs exceed the amount
of royalties withheld by TGC for any calendar year, TGC may to that extent
reduce the royalties due to FHCRC from TGC in succeeding calendar years, but
never by more than fifty percent (50%) of the royalty due in any one year.  Any
unused royalty credit amount may be carried forward until the full amount of the
credit has been exhausted.

     8.3  Recoveries or reimbursements from such Action shall first be applied
to reimburse TGC and FHCRC for litigation costs not paid from royalties (if any)
and 

                                       9

                                                 TGC EXCLUSIVE LICENSE AGREEMENT
 
then to reimburse FHCRC for royalties withheld.  Any remaining recoveries or
reimbursements shall be shared equally by TGC and FHCRC.

     8.4  In the event that TGC elects not to exercise its option to prosecute
an infringement of the LICENSED PATENT RIGHTS pursuant to this Agreement, FHCRC
may do so at its own expense, controlling such Action and retaining all
recoveries therefrom.

                      ARTICLE 9 - TERMINATION OF AGREEMENT

     9.1  Unless terminated earlier in accordance with the terms hereof, this
Agreement will expire upon the expiration of the Term as provided in Article 3.
Upon termination, a final report shall promptly be submitted in accordance with
the provisions of Section 5.4, together with any royalty payments and
unreimbursed patent expenses due to FHCRC.

     9.2  At FHCRC's option, FHCRC may terminate this Agreement sixty (60) days
after giving written notice to TGC of any default in payments due hereunder and
subsequent failure by TGC to remedy any such default within such period,
provided that FHCRC is not then in breach of any provision hereof.

     9.3  This Agreement may be terminated by either party upon breach of a
material obligation or condition by the other (other than a breach according to
Section 9.2), effective ninety (90) days after giving written notice to the
other of such termination under this Article and specifying such breach,
provided however, that if the breach is cured or shown to be non-existent within
the ninety (90) day period, the notice shall be deemed automatically withdrawn
and of no effect.  If the parties do not agree whether a breach has occurred or
been cured or whether it is "material", the dispute shall be resolved through
arbitration under Article 13.

     9.4  Subject to any provisions of the federal bankruptcy laws limiting
rights of termination, this Agreement will automatically terminate if TGC files
for protection under federal bankruptcy laws, becomes insolvent, makes an
assignment for the benefit of creditors, appoints or suffers appointment of a
receiver or trustee over its property, files a petition under any bankruptcy or
insolvency act or has any such petition filed against it or files for
dissolution.

     9.5  Any sublicenses granted by TGC under this Agreement shall provide for
termination or assignment to FHCRC, at the option of FHCRC, of TGC's interest
therein upon termination of this Agreement.

     9.6  TGC shall have the right to terminate this Agreement effective thirty
(30) days after giving written notice to FHCRC of termination under this
Article.

     9.7  Upon termination of this Agreement, TGC shall have the right for three
(3) months to sell all LICENSED PRODUCTS on hand at the time of notification of
termination if the royalties from such sales and any and all other payments due
FHCRC are paid to and statements rendered to FHCRC with respect to such LICENSED
PRODUCTS when due in accordance with this Agreement.

     9.8  Upon termination of the Agreement for any reason, and subject to TGC's
rights under Section 9.7, TGC shall return to FHCRC and thereafter continue to
maintain the confidentiality thereof, and refrain from use thereof or the
disclosure thereof to any third party as required by Article 15, and all other
rights in LICENSED PROCESSES and LICENSED PRODUCTS granted to TGC under Article
2 shall expire and revert to FHCRC.  Immediately upon cessation of discussions
between TGC and FHCRC during the Term, or upon request by one of the parties,
TGC and FHCRC will return all Proprietary Information of the other, and all
documents or data storage media containing any such Proprietary Information and
any and all copies thereof, and TGC and FHCRC will delete all Proprietary
Information of the other from its documents or data storage media, except that
the parties shall maintain one copy of such Proprietary Information in their
legal or corporate development files.

     9.9  Should either party terminate this Agreement as permitted herein, the
other party shall not be able to claim from the terminating party any damages or
compensation for losses or expenses incurred solely as a result of the
termination.

     9.10  Provisions hereof and accrued rights hereunder which by their terms
or nature survive the termination or expiration of this Agreement shall so
survive such termination or expiration.

                   ARTICLE 10 - REPRESENTATIONS AND COVENANTS

     10.1  FHCRC represents and warrants that all right, title, and interest in
the patent applications or patents comprising the LICENSED PATENT RIGHTS have
been assigned to it and that FHCRC has the authority to issue licenses under
said LICENSED PATENT RIGHTS.  FHCRC disclaims all implied or express warranties
of any nature whatsoever concerning the validity of the LICENSED PATENT RIGHTS
licensed hereunder.  TGC acknowledges and agrees that neither FHCRC nor anyone
acting on its behalf has made any representations whatsoever with regard to the
scope of the LICENSED PATENT RIGHTS or that such LICENSED PATENT RIGHTS may be
exploited by TGC, an AFFILIATE, or sublicensee without infringing other patents.

subdivisions, having, asserting or claiming jurisdiction over TGC or TGC's
performance of the terms of this Agreement.  In particular, TGC:

          (a)  will be responsible for obtaining all necessary United States
               Food and Drug Administration approvals and all approvals required
               by similar governmental bodies or agencies of all applicable
               foreign countries; and

          (b)  understands and acknowledges that the transfer of certain
               commodities and technical data is subject to United States laws
               and regulations controlling the export of such commodities and
               technical data, including all Export Administration Regulations
               of the United States Department of Commerce.  These laws and
               regulations, among other things, prohibit or require a license
               for the export of certain types of technical data to certain
               specified countries.  TGC hereby agrees and gives written
               assurance that it will comply with all United States laws and
               regulations controlling the export of commodities and technical
               data, that it will be solely responsible for any violation of
               such by TGC or its AFFILIATES or sublicensees, and that it will
               defend and hold FHCRC harmless in the event of any legal action
               of any nature occasioned by such violation.

                           ARTICLE 11 - LEGAL ACTION

     11.1  In the event any legal action is commenced against TGC involving
TECHNOLOGY or a LICENSED PRODUCT or otherwise relating to this Agreement,
whether or not FHCRC is named as a party to the legal action, TGC shall keep
FHCRC or its attorney nominee fully advised of the progress of the legal action

                                                 TGC EXCLUSIVE LICENSE AGREEMENT
 
and shall reimburse FHCRC for its reasonable legal costs (including attorney's
fees) incurred as a result of FHCRC's monitoring of such action, FHCRC's being
named a party to any such legal action, or when FHCRC's employees or agents are
called as witnesses therein or asked to testify for or consult with TGC in
connection therewith.

     11.2  FHCRC agrees to cooperate with TGC, to the extent reasonably
possible, in any legal action brought pursuant to this Article 11.

                           ARTICLE 12 - HOLD HARMLESS

     12.1  TGC assumes responsibility for and shall defend, indemnify and hold
FHCRC, its directors, officers, managers, agents, students, doctors and
employees harmless from any and all liability, losses, expenses, damages,
assessments and claims arising out of or resulting from (i) the use, sale or any
disposition of LICENSED PRODUCTS, (ii) the practice of the LICENSED PROCESSES by
TGC or its AFFILIATES, or (iii) the use, sale or other disposition of the
LICENSED PRODUCT or LICENSED PROCESSES by others who receive LICENSED PRODUCTS
or LICENSED PROCESSES directly or indirectly from TGC, its AFFILIATES, agents or
representatives.

                            ARTICLE 13 - ARBITRATION

     13.1  Any dispute, other than a question relating to patent validity,
between the parties hereunder which cannot be resolved by good faith negotiation
between the parties over a period of at least sixty (60) days shall be resolved
by arbitration before a panel of three arbitrators under the then current rules
and procedures of the American Arbitration Association (the "AAA"), or other
rules and procedures as the parties may agree.  Each party shall bear its own
costs incurred in connection with such arbitration and the fees, expenses and
costs of the AAA, the arbitrator(s) and the arbitration proceeding not incurred
solely by one party shall be divided equally between the parties.  The arbitral
award shall be binding and conclusive on both parties and may be enforced in any
court of competent jurisdiction.

                              ARTICLE 14 - NOTICES

     14.1  All communications, including payments, notices, demands or requests
required or permitted to be given hereunder, shall be given in writing and shall

                    confidential and patent applications;

               (ii) oral disclosures, the content of which is within thirty (30)

               (iii) information that is demonstrated by a preponderance of the
                    evidence to have been independently developed by the

                    Information disclosed by the disclosing party; and

license or use any intellectual property right (including but not limited to any
patent right obtained by the disclosing party) relating to the Proprietary

marked by its sublicensees every LICENSED PRODUCT manufactured, used or sold by
TGC, its AFFILIATES or its sublicensees in accordance with the statutes of the
United States relating to the marking of patented articles.

                         ARTICLE 17 - RIGHT TO PUBLISH

     17.1  Nothing in this Agreement shall be construed as prohibiting FHCRC or
its researchers from publishing any of the results of research on the TECHNOLOGY
in reputable scientific journals. Notwithstanding the foregoing, it is expected
the FHCRC shall take such measures to obtain appropriate patent or other
protection for any inventions which FHCRC reasonably knows will be incorporated
into the LICENSED PATENT RIGHTS as a continuation or a continuation-in-part.

                           ARTICLE 18 - MISCELLANEOUS

     18.1  The rights and obligations of the parties under this Agreement shall

     18.2  This Agreement may not be amended except by an instrument in writing
signed by both parties.

     18.3  The Agreement shall be binding on the parties hereto and upon their
respective heirs, administrators, successors and assigns. This Agreement may not
be assigned or sublicensed by TGC or by operation of law without the prior
written consent of FHCRC.

     18.4  TGC acknowledges that FHCRC is a non-profit organization qualifying
for and holding the status of an exempt organization under Section 501(c)(3) of
the United States Internal Revenue Code. If the Internal Revenue Service
determines, or a determination by FHCRC based on advice of legal or tax counsel
is reasonably made, that any part or all of this Agreement will jeopardize
FHCRC's Section 501(c)(3) status, the parties agree to meet and confer in good
faith to amend this Agreement to the extent necessary to satisfy Internal
Revenue Service requirements for retention of FHCRC'S Section 501(c)(3) status.
If FHCRC and TGC cannot agree within 30 days after commencing negotiations
regarding the amendments to be made to this Agreement in order for FHCRC to
retain its Section 501(c)(3) status, FHCRC may terminate this Agreement
effective upon giving written notice to TGC of termination under this Article
18.

     18.5  TGC understands and acknowledges that agreements between FHCRC and
agencies of the United States Government funding FHCRC's programs may contain
clauses granting patent and/or other rights to the agencies or the U.S.
Government; TGC agrees that the rights granted to it under this Agreement shall
be subject to any rights of the agencies and the U.S. Government. In the event
of a conflict between any of the provisions of this Agreement and the provisions
of any U.S. Government agency funding agreement and/or regulation shall prevail
and FHCRC will have no liability to TGC as a result of such conflict.

     18.6  Except as otherwise provided herein, FHCRC and its employees,
including but not limited to the INVESTIGATORS, shall not use the name of TGC,
its employees or agents, and TGC, including its employees, shall not use the
name of FHCRC or any of its employees or agents in any advertising, publicity,
news release, promotional materials or any public disclosure, whatsoever, EITHER
WRITTEN OR ORAL, related to the existence of this Agreement or any actions or
work undertaken pursuant to terms of this Agreement without the prior written
consent of the other party. FHCRC shall have three (3) business days from the
time it receives a proposed disclosure ("Review Period") to approve and/or
provide comments to TGC with respect to such disclosure. In the event that TGC
receives no communications from 

                                      17
<PAGE>
 
                                                 TGC EXCLUSIVE LICENSE AGREEMENT
 
FHCRC regarding such disclosure within the Review Period, then FHCRC's consent
of the public release of such disclosure shall be deemed to have been granted.

     18.7  Upon the earlier of any:  (i) testing or use in human subjects or
(ii) sale of a LICENSED PRODUCT, TGC will have FHCRC named as an additional
insured on TGC'S product liability insurance policies, with limits of at least
$1,000,000 per claim and $5,000,000 annual aggregate. Such policies shall not be
terminated without thirty (30) days prior written notice to FHCRC. If FHCRC's
insurance costs can be shown to have increased solely because of this Agreement,
and such increases are verified by an independent certified public accountant,
TGC shall reimburse FHCRC for such increase within twenty (20) days of receiving
written notice from FHCRC requesting such reimbursement and the parties shall
attempt to agree to changes and revisions of this Agreement. If the parties fail
to arrive at agreement within a reasonable time, or TGC does not reimburse
FHCRC, FHCRC may by written notice terminate this Agreement.

     18.8  All letters, documents, or other materials of a written or physical
nature, required by or relating to this Agreement shall be in English and sent
to the party at the address given in Article 14.

     18.9  The parties to this Agreement recognize and agree that each is
operating as an independent contractor and not as an agent of the other. This
Agreement shall not constitute a partnership or joint venture, and neither party
may be bound by the other to any contract, arrangement or understanding except
as specifically stated herein.

     18.10  Should a court of competent jurisdiction later consider any
provision of this Agreement to be invalid, illegal, or unenforceable, it shall
be considered severed from this Agreement. All other provisions, rights and
obligations shall continue without regard to the severed provision, provided
that the remaining provisions of this Agreement are in accord with the intention
of the parties.

     18.11  In the event any party to this Agreement commences any action or
proceeding, including an appeal of an action or proceeding, against the other,
or otherwise retains an attorney, by reason of any breach or claimed breach of
any provision of this Agreement, or to seek a judicial declaration of rights
hereunder or judicial or equitable relief, the prevailing party in such action
or proceeding shall be entitled to recover its reasonable attorneys' fees and
costs. At the option of FHCRC, venue of any such legal or equitable action shall
lie in Seattle, Washington. TGC hereby submits to the jurisdiction of the
Federal District Court of Western Washington located in Seattle, Washington, and
hereby agrees to accept service of process by certified mail, return receipt
requested, effective upon delivery to TGC.

                       ARTICLE 2 - GRANT AND SUBLICENSES
                       ---------------------------------

     2.1  License Grant.  INSTITUTE hereby grants to LICENSEE the exclusive
          license right to make, use, sell, import and export (subject to the
          provisions of Article 9) LICENSED PRODUCTS and LICENSED PROCESSES in
          the TERRITORY, for use in the FIELD OF USE.  This license grant will
          continue until the last to expire of the PATENT RIGHTS, unless this
          Agreement is terminated sooner according to the terms hereof.  This
          license grant is subject to the governmental rights referenced in
          Recital A and to the reserved rights referenced in Paragraph 2.2
          hereof.

     2.2  Reserved Rights.  INSTITUTE reserves the right to (a) practice and
          have practiced the PATENT RIGHTS for noncommercial purposes; and (b)
          use and distribute to third parties material covered by the PATENT
          RIGHTS for noncommercial research purposes and (c) grant to others the
          right to practice the PATENT RIGHTS to make use or sell products that
          are not LICENSED PRODUCTS and LICENSED PROCESSES.  INSTITUTE will
          notify LICENSEE of any pending distribution of materials covered by
          the PATENT RIGHTS to commercial third parties and its intention to
          grant licenses per (b) and (c) of this section, respectively, at least
          thirty (30) days prior to such planned distribution.

                                      -3-
<PAGE>
 
          LICENSEE will have the right to request that materials covered by the
          PATENT RIGHTS not be distributed or licenses not granted, and such
          request will not be unreasonably denied by the INSTITUTE.

     2.3  No Implied Rights.  The license granted hereunder will not be
          construed to confer any rights upon LICENSEE by implication, estoppel
          or otherwise as to any technology not specifically set forth in
          Appendix A hereof.

     2.4  Sublicensing.  LICENSEE will have the right to enter into sublicensing
          agreements for the rights, privileges and licenses granted hereunder,
          subject to the INSTITUTE'S prior written approval, which approval will
          not be unreasonably denied.  Upon any termination of this Agreement,
          sublicensees' rights will also terminate, subject to Paragraph 13.6
          hereof.

     2.5  Binding on Sublicensee.  LICENSEE agrees that any sublicenses granted
          by it will provide that all obligations of LICENSEE to INSTITUTE
          created by this Agreement will be binding upon the sublicensee as if
          it were a party to this Agreement.

     2.6  No Extra Consideration from Sublicensee.  LICENSEE will not receive
          from sublicensees anything of value in lieu of cash payments in
          consideration for any sublicense under this Agreement, without the
          express prior written permission of INSTITUTE

                           ARTICLE 3 - DUE DILIGENCE
                           -------------------------

     3.1  Commercialization.

          (a)  LICENSEE will use its commercially reasonable efforts to bring
               LICENSED PRODUCTS to market through a thorough, vigorous and
               diligent program for exploitation of the PATENT RIGHTS and to
               continue active, diligent marketing efforts for LICENSED PRODUCTS
               throughout the life of this Agreement.

          (b)  LICENSEE will prepare and furnish to INSTITUTE an annual
               development and progress report, as of June 30 of each year,
               describing LICENSEE'S progress (and sublicensee's plans) for the
               development and commercialization of LICENSED PRODUCTS.

          (c)  So long as LICENSEE is pursuing commercially reasonable efforts
               to bring to market and to diligently market at least one

                                      -4-
<PAGE>
 
               LICENSED PRODUCT, including meeting the milestones for said
               LICENSED PRODUCT as specified in Paragraph 3.2, below, then
               INSTITUTE will not be entitled to terminate this Agreement on
               account of a default under this Paragraph 3.1.

     3.2  Milestones.  In addition, LICENSEE will adhere to the following
          milestones:

          (a)  Initiate first Phase II clinical trial for a product covered by
               the PATENT RIGHTS not more than [ * ] from the Effective Date;
               and

          (b)  Initiate first Phase III clinical trial for a product covered by
               the PATENT RIGHTS not more than [ * ] from the Effective Date;
               and

          (c)  File a New Drug Application for a product covered by the PATENT
               RIGHTS not more than [ * ] years from the Effective Date; and

          (d)  Receive approval of a New Drug Application for a product covered
               by the PATENT RIGHTS not more than [ * ] years from the Effective
               Date.

     3.3  If LICENSEE fails to achieve the milestones described in Paragraph 3.2
          (a), then the INSTITUTE has the option, in its sole discretion, to
          terminate this Agreement, or to convert the exclusive license granted
          by this Agreement to a non-exclusive license.

     3.4  LICENSEE may request INSTITUTE approval to modify the milestones
          described in Paragraph 3.2 (b)-(d).  If LICENSEE can reasonably
          demonstrate that such failure is attributable to causes outside of its
          control, INSTITUTE approval of such request will not be unreasonably
          denied.  If such failure is attributable to causes within LICENSEE'S

          control then the INSTITUTE has the option, in its sole discretion, to
          consider such failure a material breach or default of this Agreement
          and may exercise its right to terminate this Agreement pursuant to
          Paragraph 13.3 hereof.

               ARTICLE 4 - LICENSE FEES, ROYALTIES AND MILESTONES
               --------------------------------------------------

     4.1  License Fees and Stock Warrants.  In consideration of the license
          granted LICENSEE pursuant to Article 2 hereof, LICENSEE will pay
          and/or deliver to the INSTITUTE:

          (a)  a license fee of [ * ] cash payable as follows:

               [ * ] already paid by LICENSEE upon execution of the term sheet
               that outlined the terms of this Agreement, receipt of which is
               hereby acknowledged; [ * ] due within thirty (30) days after the
               Effective Date; and [ * ] due on or before six months after the
               Effective Date.

          (b)  a stock warrant to purchase 50,000 of LICENSEE'S common stock at
               the market price as of the Effective Date of this Agreement,
               which warrant will be exercisable for a period of seven years
               after the Effective Date.  Such warrant will vest as follows:

               1.   16,667 shares upon the Effective Date of this Agreement;

               2.   16,666 shares upon successful completion by INSTITUTE of 
                    [ * ], provided that such studies are completed within one
                    (1) year after the Effective Date, and provided further that
                    if such studies are not completed within one (1) year after
                    the Effective Date such warrant for these 16,666 shares will
                    be rescinded;

               3.   16,667 shares upon issuance of a US patent covering [ * ].

     4.2  Running Royalties.

          (a)  LICENSEE will pay to the INSTITUTE running royalties of
               [ * ] of NET SALES of the LICENSED



[*]  Confidential Treatment Requested

                                      -6-
<PAGE>
 
               made, used or sold by LICENSEE or sublicensees; provided however,
               if there are multiple, stacking royalties payable by LICENSEE on
               the LICENSED PRODUCTS to third parties, then LICENSEE may reduce
               the [ * ] royalty to INSTITUTE on the same proportionate basis as
               all of the other stacking royalties are reduced, so long as the
               resulting royalty payable to the INSTITUTE does not go below 
               [ * ] of NET SALES of LICENSED PRODUCTS.

          (b)  In the case of NET SALES of LICENSE PRODUCTS by sublicensees,
               INSTITUTE will be paid the greater of the running royalties
               specified in Paragraph 4.2(a) or [ * ] of the royalties payable
               by the sublicensee to LICENSEE.

          (c)  In the case of a sublicense which pays any consideration to
               LICENSEE other than running royalties on NET SALES of LICENSED
               PRODUCTS ("Non-Royalty Fees") (e.g. such other consideration
               includes license fees, marketing fees, milestone payments, equity
               in sublicensee, bonus payments and the like - but excludes
               specific funding for specific future research and development
               work and purchases of equity in LICENSEE) then LICENSEE will pay
               [ * ] of said other consideration to INSTITUTE. In the event that
               LICENSEE sublicenses the PATENT RIGHTS to a third party in
               combination with patent(s) and or other rights of the University
               of Texas MD Anderson Cancer Center ("MDACC") for which LICENSEE
               receives Non-Royalty Fees, then the INSTITUTE's share of Non-
               Royalty Fees will be reduced from [ * ] to the amount of
               reduction from [ * ] agreed to by MDACC, but in no event will the
               INSTITUTE's share of Non-Royalty Fees be reduced to less than 
               [ * ].

          (d)  Payments of royalties will be made within thirty (30)days after
               March 31, June 30, September 30 and December 31 of each year
               during the term of this Agreement covering LICENSED PRODUCTS sold
               during the preceding calendar quarter. Payments of other
               consideration pursuant to Paragraph 4.2(c) will be made within
               thirty (30) days after receipt by LICENSEE.

     4.3  Milestone Payments.  LICENSEE will pay to the INSTITUTE the following
          milestone payments, due as follows:

          (a)  [ * ] upon achievement of the milestone outlined in Paragraph
               3.2(a); and

          (b)  [ * ] upon achievement of the milestone outlined in Paragraph
               3.2(b); and

          (c)  [ * ] upon achievement of the milestone outlined in Paragraph
               3.2(c); and

          (d)  [ * ] upon achievement of the milestone outlined in Paragraph
               3.2(d)

     4.4  Minimum Sales.  From and after the date of the first commercial sale
          of a LICENSED PRODUCT, in each of the three succeeding calendar yeras,
          LICENSEE will pay to the INSTITUTE royalties of not less than [ * ]
          ("Minimum Royalties"). In each calendar year thereafter LICENSEE will
          achieve sales of LICENSED PRODUCTS sufficient to produce royalties
          payable to the INSTITUTE of not less than [ * ]. If LICENSEE fails to
          achieve such sales after three (3) full calendar years from the date
          of the first commercial sale, INSTITUTE may either terminate this
          Agreement or convert the license rights from exclusive to non-
          exclusive. Minimum Royalties for the first year of commercial sales
          will be pro-rated according to the month when such sales begin.

     4.5  Net of Taxes.  All payments due hereunder will be paid in full,
          without deduction of taxes or other fees which may be imposed by any
          government (excluding however any US income taxes which may be payable
          by INSTITUTE), and which taxes and fees will be paid by LICENSEE.

     4.6  No Multiple Royalties.  No multiple royalties will be payable to
          INSTITUTE because any LICENSED PRODUCT is covered by more

<PAGE>
 
          than one patent or patent application included in the PATENT RIGHTS
          licensed under this Agreement.

     4.7  US Dollar Payments.  Royalty payments will be paid in United States
          dollars in San Diego, California, or at such other place as INSTITUTE
          may reasonably designate consistent with the laws and regulations
          controlling in any foreign country. If any currency conversion will be
          required in connection with the payment of royalties hereunder, such
          conversion will be made by using the exchange rate prevailing at the
          Chase Manhattan Bank (NA) on the last business day of the calendar
          quarterly reporting period to which such royalty payments relate.

                        ARTICLE 5 - REPORTS AND RECORDS
                        -------------------------------

     5.1  LICENSEE'S Books; Inspection.  LICENSEE will keep full, true and
          accurate books of account containing all particulars that may be
          necessary for the purpose of showing the amounts payable to INSTITUTE
          hereunder. Said books of account will be kept at LICENSEE's principal
          place of business or the principal place of business of the
          appropriate division of LICENSEE to which this Agreement relates.
          Said books and the supporting data will be open and made available for
          inspection by the INSTITUTE and/or its agents not less than seven (7)
          days after receipt by LICENSEE of INSTITUTE'S advance written notice
          of its intent to inspect said books and data for three (3) years
          following the end of the calendar year to which they pertain, for the
          purpose of verifying LICENSEE's royalty statement or compliance in
          other respects with this Agreement.  Such inspection may be conducted
          no more frequently than annually.  Should such inspection lead to the
          discovery of a greater than ten percent (10%) discrepancy in reporting
          to INSTITUTE's detriment, LICENSEE agrees to pay the full cost of such
          inspection.

     5.2  Annual Development Reports.  Before the first commercial sale of a
          LICENSED PRODUCT, LICENSEE will submit to INSTITUTE annual reports on
          June 30 of each year as to LICENSEE'S activities, progress and plans
          applicable to Paragraphs 3.1 and 3.2.

     5.3  Quarterly Royalty Reports.  Within thirty (30) days after the
          expiration of each calendar quarter commencing with the quarter in
          which the first commercial sale occurs of a LICENSED PRODUCT, LICENSEE
          will deliver to INSTITUTE a written statement of all royalties due on
          sales of LICENSED PRODUCTS during such calendar quarter.  Such written

                                      -9-
<PAGE>
 
          statements will be duly signed on behalf of LICENSEE  and will show
          the NET SALES  of LICENSED PRODUCTS sold by LICENSEE and/or its
          sublicensees during such calendar quarter and the amount of royalties
          due, pursuant to section 4.2.  If no royalties are due, LICENSEE will
          so report.

     5.4  Late Payment Charge.  The payments set forth in this Agreement will,
          if overdue, bear interest until paid at a per annum rate equal to two
          percent (2%) above the prime rate in effect at the Chase Manhattan
          Bank (NA) on the due date.  The payment of such interest will not
          preclude INSTITUTE from exercising any other rights it may have as a
          consequence of the lateness of any payment.

                         ARTICLE 6 - PATENT PROSECUTION
                         ------------------------------

     6.1  LICENSEE'S Payment of Patent Costs.  Payment of all reasonable fees
          and costs relating to the filing, prosecution, and maintenance of the
          PATENT RIGHTS incurred after December 1, 1996, will be the
          responsibility of LICENSEE, and will be paid by LICENSEE.

     6.2  INSTITUTE'S Duty.  Subject to LICENSEE'S payment of the reasonable
          costs, INSTITUTE will apply for, seek prompt issuance of, and maintain
          during the term of this Agreement the PATENT RIGHTS in the United
          States and in the foreign countries listed in Appendix B hereto.
          Appendix B may be amended by written agreement of both parties.  The
          prosecution, filing and maintenance of all PATENT RIGHTS will be the
          primary responsibility of INSTITUTE; provided, however, that INSTITUTE
          will keep LICENSEE fully informed of the progress thereof, and will
          provide LICENSEE with copies of all documents related to filing,
          prosecuting and maintaining the PATENT RIGHTS, and a reasonable
          opportunity to review any proposed application, amendment, response or
          other communication related to the PATENT RIGHTS; and the INSTITUTE
          will use its best efforts to accommodate LICENSEE'S reasonable
          requests regarding filing, prosecuting and maintaining the PATENT
          RIGHTS.

                            ARTICLE 7 - INFRINGEMENT
                            ------------------------

     7.1  Prosecution of Infringement Action.  If it is believed in good faith
          that the PATENT RIGHTS are infringed by a third party as evidenced by
          a third party's manufacture, use or sale of a product, the party to
          this Agreement first having knowledge of such infringement will
          promptly

                                     -10-
<PAGE>
 
          notify the other party in writing, which notice will set forth the
          facts of such infringement in reasonable detail. LICENSEE will have
          the right, but not the obligation, to institute and prosecute at its
          own expense any such infringement of the PATENT RIGHTS to enjoin any
          third party infringement of the PATENT RIGHTS in such third party's
          efforts to make, use or sell a product and to recover damages as may
          be awarded. If LICENSEE fails to bring such action or proceedings
          within a period of three (3) months after receiving written notice or
          otherwise having knowledge of such infringement, then INSTITUTE will
          have the right, but not the obligation, to prosecute at its own
          expense any infringement of the PATENT RIGHTS. In either instance in
          which one party to this Agreement institutes an infringement action,
          the second party will agree to be joined as a party plaintiff if
          required by law, and at the expense of the first party, and the second
          party further agrees to give the first party reasonable assistance and
          authority to file and to prosecute such suit. Any recovery of damages
          and costs in such suits will be apportioned as follows: the party
          bringing the suit will first recover an amount equal to two (2) times
          the costs and expenses incurred by the party directly related to the
          prosecution of such action, and the remainder will be divided equally
          between the INSTITUTE and LICENSEE.

     7.2  Consent to Settlement.  No settlement or consent judgment or other
          voluntary final disposition of a suit under this Article may be
          entered into without the consent of the INSTITUTE and/or LICENSEE,
          which consents will not be unreasonably withheld.

     7.3  Sublicense to Infringer.  LICENSEE will have the sole right to grant a
          sublicense to any alleged infringer for the FIELD OF USE to make, use
          or sell LICENSED PRODUCTS, subject to compliance with all of the terms
          and conditions, including Paragraph 2.4, of this Agreement.

                         ARTICLE 8 - PRODUCT LIABILITY
                         -----------------------------

     8.1  Indemnity.  LICENSEE will at all times during the term of this
          Agreement and thereafter, indemnify, defend and hold INSTITUTE, its
          trustees, directors, officers, employees and affiliates, harmless
          against all claims, proceedings, demands and liabilities of any kind
          whatsoever, including legal expenses and reasonable attorneys' fees,
          arising out of the death of or injury to any person or persons or out
          of any damage to property, or resulting from the testing, production,
          manufacture, sale, use, lease, consumption or advertisement of the
          LICENSED PRODUCT(s) or arising from any obligation of LICENSEE
          hereunder,

                                     -11-
<PAGE>
 
          excepting only claims that the PATENT RIGHTS infringe third party
          intellectual property.

     8.2  Insurance.  LICENSEE will obtain and carry in full force and effect
          liability insurance which will protect LICENSEE and INSTITUTE with
          respect to events covered by Paragraph 8.1, above, as soon as
          commercially practical, but in no event later than the earlier of the
          commencement of any clinical trial for or the first sale of a LICENSED
          PRODUCT or first practice of a LICENSED PROCESS. The limits of such
          insurance will not be less than One Million Dollars ($1,000,000) per
          occurrence with an aggregate of Three Million Dollars ($3,000,000) for
          personal injury or death, and One Million Dollars ($1,000,000) per
          occurrence with an aggregate of Three Million Dollars ($3,000,000) for
          property damage and such insurance will be endorsed to included
          clinical trials or product liability coverage as the circumstances may
          require.  LICENSEE will provide INSTITUTE with Certificates of
          Insurance evidencing the same and will provide ten (10) days written
          notice to INSTITUTE prior to any cancellation or material change
          thereof.  LICENSEE will have INSTITUTE named as an additional insured
          on such insurance prior to the date of the first commercial sale of a
          LICENSED PRODUCT or the practice of a LICENSED PROCESS.  Additionally,
          LICENSE will use its best efforts to have INSTITUTE named as an
          additional insured on such insurance prior to the commencement of any
          clinical trial for a LICENSED PRODUCT or LICENSED PROCESS.  If,
          however, LICENSEE is unable to have INSTITUTE named as an additional
          insured on such insurance prior to the commencement of any clinical
          trial for a LICENSED PRODUCT or LICENSED PROCESS, LICENSEE will so
          advise INSTITUTE prior to the commencement of such clinical trial and
          the INSTITUTE and LICENSEE will negotiate in good faith alternative
          means to protect the INSTITUTE with respect to events covered by
          Paragraph 8.1 during the period of such clinical trial.

     8.3  Disclaimers by INSTITUTE.  EXCEPT AS OTHERWISE EXPRESSLY SET FORTH IN
          THIS AGREEMENT, INSTITUTE, ITS TRUSTEES, DIRECTORS, OFFICERS,
          EMPLOYEES, AND AFFILIATES MAKE NO REPRESENTATIONS AND EXTEND NO
          WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED, INCLUDING BUT NOT
          LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR
          PURPOSE, VALIDITY OF PATENT RIGHTS CLAIMS, ISSUED OR PENDING,

                                     -12-
<PAGE>
 
          AND THE ABSENCE OF LATENT OR OTHER DEFECTS, WHETHER OR NOT
          DISCOVERABLE. NOTHING IN THIS AGREEMENT WILL BE CONSTRUED AS A
          REPRESENTATION MADE OR WARRANTY GIVEN BY INSTITUTE THAT THE PRACTICE
          BY LICENSEE OF THE LICENSE GRANTED HEREUNDER WILL NOT INFRINGE THE
          PATENT RIGHTS OF ANY THIRD PARTY. IN NO EVENT WILL INSTITUTE, ITS
          TRUSTEES, DIRECTORS, OFFICERS, EMPLOYEES AND AFFILIATES BE LIABLE FOR
          INCIDENTAL OR CONSEQUENTIAL DAMAGES OF ANY KIND, INCLUDING ECONOMIC
          DAMAGE OR INJURY TO PROPERTY AND LOST PROFITS, REGARDLESS OF WHETHER
          INSTITUTE WILL BE ADVISED, WILL HAVE OTHER REASON TO KNOW, OR IN FACT
          WILL KNOW OF THE POSSIBILITY.

     8.4  Representations by INSTITUTE.  INSTITUTE hereby makes the
          representations as set forth in Recital A of this Agreement.

                          ARTICLE 9 - EXPORT CONTROLS
                          ---------------------------

     It is understood that INSTITUTE is subject to United States laws and
regulations controlling the export of technical data, computer software,
laboratory prototypes and other commodities (including the Arms Export Control
Act, as amended and the Export Administration Act of 1979), and that its
obligations hereunder are contingent on compliance with applicable United States
export laws and regulations. The transfer of certain technical data and
commodities may require a license from the cognizant agency of the United States
Government and/or written assurances by LICENSEE that LICENSEE will not export
data or commodities to certain foreign countries without prior approval of such
agency. INSTITUTE neither represents that a license will not be required nor
that, if required, it will be issued.

                         ARTICLE 10 - NON-USE OF NAMES
                         -----------------------------

     LICENSEE will not use the names or trademarks of The Burnham Institute, nor
any adaptation thereof, nor the names of any of their employees, in any
advertising, promotional or sales literature without prior written consent
obtained from INSTITUTE, or said employee, in each case, except that LICENSEE
may state that it is licensed by INSTITUTE under one or more of the patents
and/or applications comprising the PATENT RIGHTS.  INSTITUTE will not use the
name of the LICENSEE in any public disclosure without the prior written consent
of the LICENSEE.

                            ARTICLE 11 - ASSIGNMENT
                            -----------------------

     This Agreement is not assignable by LICENSE without the express prior
written consent of the INSTITUTE except in the event of the sale of all or
substantially all of the LICENSEE'S assets and/or business.   Any other attempt
to assign this Agreement without such consent will be void. This Agreement will
bind and inure to the benefit or permitted assigns.

                        ARTICLE 12 - DISPUTE RESOLUTION
                        -------------------------------

     12.1  Arbitration.  All disputes arising between the INSTITUTE and LICENSEE
           under this Agreement will be settled by binding arbitration conducted
           in the English language in accordance with and US laws with the
           Commercial Arbitration Rules of the American Arbitration Association.
           The parties will cooperate with each other in causing the arbitration
           to be held in an efficient and expeditious manner. Any arbitration
           proceeding instituted under this Agreement will be brought in the
           state and county of the principal executive offices of the party
           against which the arbitration is initiated.

     12.2  Award.  Any award rendered by the arbitrators will be final and
           binding upon the parties hereto. Judgment upon the award may be
           entered in any court of record of competent jurisdiction. Each party
           will pay its own expenses of the arbitration, and the expenses of the
           arbitrators will be equally shared, unless the arbitrators assess as
           part of their award all or any part of the arbitration expenses of
           one party (including reasonable attorneys' fees) against the other
           party.

     12.3  Jurisdiction.  The law governing this Agreement, for purposes of the
           arbitration will be the law of the state of the principal offices of
           the party against which the arbitration is initiated.

     12.4  No Waiver.  Notwithstanding the foregoing, nothing in this Article
           will be construed to waive any rights or timely performance of any
           obligations existing under this Agreement.

                            ARTICLE 13 - TERMINATION
                            ------------------------

     13.1  Cessation of Business by LICENSEE.  If LICENSEE will cease to carry
           on its business, this Agreement will terminate upon notice by
           INSTITUTE.

                                     -14-
<PAGE>
 
     13.2  Payment Default by LICENSEE.  If LICENSEE fails to make any payment
           due and payable to INSTITUTE hereunder, INSTITUTE will have the right
           to terminate this Agreement effective on thirty (30) days' written
           notice, unless LICENSEE will make all such payments to INSTITUTE
           within said thirty (30) day period. Upon the expiration of the thirty
           (30) day period, if LICENSEE has not made all such payments to
           INSTITUTE, the rights, privileges and license granted hereunder will
           automatically terminate.

     13.3  Default by LICENSEE.  Upon any material breach or default of this
           Agreement by LICENSEE (including, but not limited to, breach or
           default under Paragraphs 3.3 or 4.4 or 8.1 or Article 11), other than
           those occurrences set out in Paragraphs 13.1 and 13.2 hereinabove,
           which will always take precedence in that order over any material
           breach or default referred to in this Paragraph 13.3, INSTITUTE will
           have the right to terminate this Agreement and the rights, privileges
           and license granted hereunder effective on ninety (90) days' written
           notice to LICENSEE. Such termination will become automatically
           effective unless LICENSEE will have cured any such material breach or
           default prior to the expiration of the ninety (90) day period.

     13.4  LICENSEE'S right to Terminate.  LICENSEE will have the right to
           terminate this Agreement at any time on six (6) months' written
           notice to INSTITUTE, and upon payment of all amounts due INSTITUTE
           through the effective date of the termination.

     13.5  Effect of Termination.  Upon termination of this Agreement for any
           reason, nothing herein will be construed to release either party from
           any obligation that matured prior to the effective date of such
           termination; and Articles 1, 8, 9, 10, 12, 13.5, 13.6, and 15 will
           survive any such termination. LICENSEE and any sublicensee thereof
           may, however, after the effective date of such termination, sell its
           then existing inventory of LICENSED PRODUCTS, and complete LICENSED
           PRODUCTS in the process of manufacture at the time of such
           termination and sell the same, provided that LICENSEE will make the
           payments to INSTITUTE as required by Article 4 of this Agreement and
           will submit the reports required by Article 5 hereof.

     13.6  Sublicenses.  Upon termination of this Agreement for any reason, any
           sublicensee will also terminate, but a sublicensee will have the
           right to seek a license from INSTITUTE. INSTITUTE agrees to negotiate
           such a license in good faith under reasonable terms and conditions
           subject to

                                     -15-
<PAGE>
 
           the INSTITUTE'S sole discretion as to whether or not to enter into a
           new license agreement.

                       ----------------------------------

re:  Amendment to the License Agreement dated March 15, 1997

Dear Dr. Lupton:

     This letter is to amend the referenced license agreement between The
Burnham Institute and Targeted Genetics Corporation.  Replacement of Paragraph
4.2(b), with the following allows for a royalty stacking provision previously
omitted from the original agreement.

     (b) In the case of NET SALES of LICENSED PRODUCTS by sublicenses, INSTITUTE
will be paid the greater of the running royalties specified in Paragraph 4.2(a)
or [ * ] of the royalties payable by the sublicensee to LICENSE; provided,
however, if there are multiple, stacking royalties payable by sublicensees on
the LICENSED PRODUCTS to third parties, then LICENSEE may reduce the payment to
INSTITUTE on the same proportionate basis as all the other stacking royalties
are reduced, so long as the resulting payment to the INSTITUTE is no less than
the greater of [ * ] of NET SALES of LICENSED PRODUCTS by sublicensees or [ * ]
of the royalties payable by the sublicensees to LICENSEE.

     Please acknowledge the amendment of the agreement by signing in the space
provided below, on both copies of this letter, and returning a copy at your
earliest convenience.

[*]  Confidential Treatment Requested

                              SECTION 1  PURPOSES

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:

</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.

                                       4
<PAGE>
 
          (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
<PAGE>
 
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, 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.  

                                       6
<PAGE>
 
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 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.

<PAGE>
 
                      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

     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.  Amended and restated by the Board on January 14,
  1997.
