ITEM 1. BUSINESS

GENERAL

     The following description of our business should be read in conjunction
with the information included elsewhere in this Annual Report on Form 10-K. The
description contains certain forward-looking statements that involve risks and
uncertainties. When used in this Annual Report on Form 10-K, the words "intend,"
"anticipate," "believe," "estimate," "plan" and "expect" and similar expressions
as they relate to us are included to identify forward-looking statements. Our
actual results could differ materially from the results discussed in the
forward-looking statements as a result of certain of the risk factors set forth
below and in the documents incorporated herein by reference, and those factors
described under " Factors Affecting Future Results". In this Annual Report on
Form 10-K, references to "VaxGen," "we," "us" and "our" refer to VaxGen, Inc.

     VaxGen, Inc. (the "Company" or "VaxGen") was formed in November 1995 to
complete the development of, and commercialize, AIDSVAX (AIDSVAX(R) is a
registered trademark of VaxGen -- AIDSVAX is the generic term used to describe
the recombinant envelope protein (gp120) vaccine. Specific designations are made
to describe the various formulations representing different strains/subtypes of
HIV, for example, AIDSVAX B, AIDSVAX B/B' and AIDSVAX B/E), a preventive HIV
vaccine. The original AIDSVAX technology was developed by Genentech, Inc.
("Genentech") and then licensed exclusively to us. VaxGen is currently testing
AIDSVAX in humans in two large-scale Phase III clinical trials. These are the
first Phase III clinical trials ever conducted for an HIV vaccine. If the Phase
III clinical trials are considered successful, we plan to apply to the United
States Food and Drug Administration (the "FDA") and foreign regulatory
authorities for licenses to manufacture and sell AIDSVAX in the United States,
Thailand and elsewhere abroad.

     Our vaccine is designed to prevent infection by HIV, rather than treat
established infection. AIDSVAX contains synthetic copies of the proteins from
the surface of HIV. Since the vaccine contains no genetic material, AIDSVAX is
incapable of causing HIV infection. Instead, humans vaccinated with AIDSVAX form
antibodies against HIV. In laboratory tests these antibodies bind to the virus
and neutralize its infectivity. Vaccination with AIDSVAX stimulates immune
memory, training the immune system to mobilize rapidly upon exposure to HIV.

     We are conducting two Phase III clinical trials of AIDSVAX to determine if
AIDSVAX will prevent infection by HIV. The North American Phase III clinical
trial is taking place in 56 clinics in the U.S., one clinic each in Puerto Rico
and in The Netherlands, and three clinics in Canada. We completed the initial
inoculation and enrollment of over 5,400 trial volunteers for the North American
Phase III clinical trial in October 1999. In Thailand, we are conducting a
second Phase III clinical trial designed for 2,500 volunteers in 17 clinical
sites in Bangkok. Based on meetings and documented discussions with the FDA and
its Vaccines and Related Biological Products Advisory Committee, we believe that
the minimum required efficacy for regulatory approval is 30%, at statistical
significance, in preventing HIV infection in volunteers vaccinated with AIDSVAX.

     Our strategy is to develop, test and obtain regulatory approval for various
formulations of AIDSVAX. The first two approvals we plan to obtain are in the
United States for the formulation being tested in the United States trial and in
Thailand for the formulation being tested in the Thai trial. We intend to use
Genentech as our partner for manufacturing and distribution. Genentech has
exclusive options to manufacture and market AIDSVAX products. If Genentech does
not exercise its options, we have the right to pursue third party arrangements,
with Genentech providing the transfer of technology necessary for manufacturing
the vaccine.

VACCINES

     Vaccines are preventive, not curative. As a result, vaccines are
particularly suited to address epidemics, even those of the magnitude of
HIV/AIDS.

                                        3
<PAGE>   4

     Vaccines prevent infection by activating the immune system to neutralize
infectious viruses. The immune system's initial response to a virus is to
produce antibodies. The antibodies bind to the virus and prevent it from
entering cells. If a virus cannot enter a cell, it is unable to multiply and
dies within a few hours in the host. This protection against infection is called
neutralization.

     Most viral infections cause lifelong immunity after natural infection. This
is because the immune system remembers that it has encountered the virus before.
Upon a subsequent encounter, it mounts such a rapid immune response that it
kills the virus before it can establish a productive infection.

     Vaccines also induce long-term memory against viruses. The immune system is
trained by vaccination with viral proteins or live viruses to rapidly respond to
and prevent subsequent viral infection.

OVERVIEW OF HIV AND AIDS

     HIV is the virus that causes AIDS, a lethal disease characterized by the
gradual deterioration of the human immune system. Although the disease is
manifested in many ways, the problem common to all patients is the destruction
of essential immune cells known as T lymphocytes, or T cells. Destruction of
these T cells by HIV makes the body particularly vulnerable to opportunistic
infections and cancers that typify AIDS and ultimately cause death. Blocking HIV
infection would prevent AIDS.

     HIV is transmitted by three predominant means; sexual contact; exposure to
blood from an infected person, such as sharing needles in drug use; and
transmission from infected mothers to their newborns.

     The HIV/AIDS epidemic is one of the largest epidemics in human history. Its
spread across the world has been documented by UNAIDS and the World Health
Organization. According to UNAIDS and the World Health Organization:

     - in 1999, 1.1% of the world's adult population was living with HIV/AIDS;

     - approximately 16,000 new infections occur each day worldwide;

     - in Sub Saharan Africa, 8.0% of the adult population is infected with HIV;
       and

     - in several African countries, HIV has infected between 20% and 26% of the
       adult population.

     In Thailand, initial infections with HIV were not reported until the
mid-1980s. It is now estimated that almost 800,000 people (2.3% of the country's
adult population) have already been infected. HIV infection has now penetrated
China, India and Indonesia, some of the most populated areas of the world. AIDS
is currently one of the top five fatal diseases worldwide.

     An estimated 920,000 people in North America are currently infected with
HIV. In North America, 44,000 new infections occur each year. According to an
earlier independent report, AIDS is one of the leading causes of death in adults
ages 25 to 44 in the United States.

        Programme on HIV/AIDS and the World Health Organization, December 1999.

     Progress recently has been made in treating HIV infection. Current HIV
therapies slow multiplication of the virus and delay onset of AIDS. They do not
cure HIV infection or AIDS. Costs of these drugs generally exceed $12,000 per
year per patient. Considering costs, difficulties in compliance with complex
drug regimens and the development of resistance to these drugs, we believe such
therapies will be available only to a small fraction of the HIV-infected
population. Thus, we believe they will probably have a minimal impact on the
worldwide epidemic.

  The HIV Infection Process

     A virus cannot replicate without entering a host cell. To make new
infectious virus particles, a virus must enter a cell and overtake its metabolic
machinery. If a virus cannot gain entry to a cell, it is incapable of surviving
for more than a few hours in the body.

     Viruses are varied in their structure and use different ways to enter
cells. HIV is a spherical virus that maintains its genetic information inside
its protein core. This core is surrounded by an outer coat called the envelope.
The envelope has protein projections, called glycoproteins that extend out from
its surface. Glycoproteins enable HIV to bind to, and subsequently enter, human
cells. The principal glycoprotein on the envelope of HIV is called gp120. To
present the proper orientation for infection, the gp120 proteins are organized
on the virus surface in clusters of three.

     HIV uses gp120 to bind to the surface of cells through a specific sequence
of interactions between the virus and its target cell. This involves a two-step
"lock and key" mechanism. The first step in this process involves the attachment
of gp120 onto a part of the target cell's surface called the CD4 receptor. A
second step occurs soon thereafter, as the gp120 protein changes shape and then
interacts with another target cell molecule called the chemokine receptor. When
this two-step process has been completed, the virus can fuse through the
target-cell membrane.

     Once inside the cell, the viral envelope opens and the core of the virus is
released, which, initiates a replication cycle that produces thousands of new
virus particles per infected cell. As it multiplies, HIV kills infected T cells
and releases new infectious virus into fluid or blood surrounding the cell. This
cycle of:

     - T cell infection;

     - viral multiplication;

     - T cell death; and

     - re-infection of new T cells

                                        5
<PAGE>   6

leads to the destruction of an essential line of immunological defense.
Substantial reduction of T cells ultimately causes increased susceptibility to
the opportunistic infections and cancers that are characteristic of AIDS.

     In addition to T cells, HIV also infects, and may reside in, blood
scavenger cells called macrophages. While infection of macrophages is not a
primary cause of AIDS, it is important in the biology of HIV and in our strategy
to prevent infection by the virus.

  Genetic Variation in HIV

     AIDS is a single disease throughout the world. At the beginning of the
epidemic, HIV was most likely limited to Africa. HIV, like any other virus,
underwent mutation to create distinct subtypes. People infected with a single
subtype of HIV then exported their infection to other places, with different
subtypes becoming predominant in different geographical areas. Subsequently, HIV
underwent further mutation to create individual strains of each subtype.

     Although the potential genetic variation in HIV might appear limitless,
only a small number of mutations confer advantage to the virus. As a result,
there are a limited number of deadly viral subtypes and strains. We believe
these fall into particular patterns providing a logical basis to formulating a
vaccine for HIV. We also believe that the major subtypes of gp120 have been
identified. Although minor subtypes are identified periodically, no new major
subtypes have been identified in the last 15 years.

     SUBTYPES. There are five major subtypes of HIV. These are labeled "A"
through "E," according to their order of discovery. The major difference between
each subtype is a genetic variation in a region of the gp120 protein known as
the chemokine-binding site.

     The major subtypes of HIV tend to be distributed along geographical lines.
This is consistent with the general understanding of how HIV has spread
throughout the world. Virtually all HIV in the Americas, Europe, the Caribbean
and Australia is subtype B. The vast majority of HIV in Thailand and in the
Pacific Rim countries is subtype E. Subtype C virus has emerged as the most
rapidly expanding HIV in Africa, China and India. The remaining subtypes A and D
occur primarily in Africa and in limited areas around the world.

     STRAINS. Each subtype of HIV is further subdivided into strains. Four
strains arise from two mutations in specific regions of the gp120 protein: a
sub-region in the chemokine-binding site and a sub-region in the CD4-binding
site. These strains are of key importance in that they have different patterns
of infection and they each react with different antibodies.

     - Chemokine-binding site. HIV has mutated at the chemokine-binding site to
       yield two distinct strains, known as T-tropic and M-tropic. Each of these
       strains binds to a chemokine receptor on a target cell. In the T-tropic
       strains, the gp120 protein binds to a chemokine receptor on T cells. In
       the M-tropic strains, the gp120 protein binds to a chemokine receptor
       found on macrophages, as well as on T cells.

     - CD4-binding site. HIV has also mutated at the CD4-binding site to yield
       two additional strains: CD4a and CD4b. Each of these strains binds with
       slight differences to the CD4 receptor, which occurs on human T cells.

     SUBTYPE/STRAIN COMBINATIONS. In summary, there are five major worldwide
subtypes of HIV: A through E. Each subtype has two different strains that bind
to chemokine receptors on T cells and macrophages. These strains are further
subdivided by two variations in the CD4-binding site on gp120. Each of these
strains requires different antibodies for neutralization.

     To construct a successful vaccine, we need to consider the entire range of
variation in gp120 and assure that we cover each of the sites on the gp120
protein that are open to attack by antibodies. Fortunately, as described above,
most of the variable sites on gp120 have only one or two principal forms. By
careful examination, we have been able to identify pairs of HIV viruses whose
gp120 proteins, when combined together in a vaccine, enhance the overall
antibody response. We believe this antibody response covers virtually the entire
range of HIV genetic variations currently known in North America and in
countries of South Asia and the Pacific Rim.

PRODUCT

  The Design of AIDSVAX

     AIDSVAX is designed to stimulate antibodies that prevent the HIV virus
infecting target cells. The antibodies attach to specific sites on gp120 protein
on the virus' surface and prevent them from binding with receptors on the target
cell. Unable to bind with and enter the cell, HIV is neutralized.

     In 1992, Genentech genetically engineered a version of the gp120 protein.
Antibodies to this gp120 protein bound to a neutralizing site found on 65% of
subtype B viruses. This virus was labeled B(MN) and was believed to represent
the majority of HIV in the United States. Subsequently, synthetic gp120 of HIV
(BMN) was incorporated into a monovalent AIDSVAX formulation, designated AIDSVAX
B.

     Genentech used this AIDSVAX B formulation to vaccinate humans in Phase I
and Phase II clinical trials. Phase I trials were used to test for dosage and
safety. Phase II trials were used to determine whether the vaccine stimulated
the desired immune system response.

     Antibodies obtained from 100% of those vaccinated with AIDSVAX B
neutralized the B(MN) virus in laboratory tests. Further tests demonstrated that
these antibodies bound to the gp120 protein of all HIV subtype B viruses tested.
However, in laboratory tests and Phase II clinical trials, antibodies to B(MN)
neutralized, to a greater extent, HIV of T-tropic strains compared to HIV of
M-tropic strains.

     To improve the breadth of the immune response, we identified a second
virus, B(GNE8), from the M-tropic strain, and a synthetic version of its gp120
protein was added to the vaccine. The resulting bivalent vaccine, AIDSVAX
B/B', which is designed to address two HIV strains, considerably expanded the
vaccine's breadth of neutralization. While the monovalent vaccine could
stimulate the production of four different types of antibodies that reacted with
binding-sites to cell receptors, the bivalent vaccine could stimulate the
production of seven. We believe that these seven antibodies cover virtually all
known strains of HIV in North America.

     As a general strategy, we plan to develop AIDSVAX formulations that will
stimulate antibodies against multiple binding sites on gp120. Our goal is to
expand the range of antibodies that are stimulated by a vaccine to neutralize a
broader group of HIV. A practical application of this strategy has been the
conversion of AIDSVAX from a monovalent to a bivalent formulation.

  Formulations of AIDSVAX

     AIDSVAX consists of two biologically active ingredients: antigens and an
adjuvant. An antigen is the ingredient in vaccines that activates the human
immune system response. The antigen in AIDSVAX is synthetic gp120 protein. An
adjuvant is an active ingredient in vaccines that improves the human immune
system response by attracting immune cells into the region where the vaccine is
injected. The adjuvant in AIDSVAX is alum, or aluminum hydroxide. Since the
vaccine contains only a synthetic fragment of the virus and no genetic material,
it is incapable of causing HIV infection.

     Three different formulations of the AIDSVAX vaccine have been developed and
clinically tested in Phase I/II trials. These include: monovalent AIDSVAX B for
HIV infections in North America and Europe, bivalent AIDSVAX B/B' for HIV
infections in North America and Europe, and bivalent AIDSVAX B/E for HIV
infections in Southeast Asia. All three formulations use alum as an adjuvant.

INITIAL TESTING OF AIDSVAX IN CHIMPANZEES

     The chimpanzee is the only laboratory animal susceptible to HIV infection.
In the initial protection trials conducted by Genentech, chimpanzees were
vaccinated with three doses of monovalent AIDSVAX B. The vaccinated animals,
along with unvaccinated control animals, were then injected intravenously with
high doses of infectious HIV of the same strain that was used for the
preparation of the vaccine. None of the AIDSVAX vaccinated animals became
infected with HIV. All of the unvaccinated control chimpanzees became infected
with HIV. HIV in chimpanzees rarely causes AIDS.

                                        7
<PAGE>   8

     In subsequent trials, chimpanzees were vaccinated with AIDSVAX B(MN) and
then injected with a different strain of HIV known as B(SF2). Despite this
difference, vaccination with AIDSVAX B(MN) conferred immunity and protection
against infection with the B(SF2) strain, while vaccination of control animals
with a placebo had no protective effect. The cross-protection observed in this
experiment documented that AIDSVAX could successfully protect animals from
infectious HIV having a genetic composition distinctly different from the virus
used to make the vaccine. Based on the results of the chimpanzee trials,
Genentech sought and received regulatory approval to commence human clinical
trials of AIDSVAX in humans.

HUMAN CLINICAL TRIALS

     Human clinical trials for vaccines involve three steps:

          - Phase I -- tests for dosage and safety;

          - Phase II -- larger-scale tests for safety, as well as a
            determination of whether the vaccine stimulates antibodies and
            immune memory; and

          - Phase III -- multi-center, placebo-controlled, double-blind tests to
            assess protection conferred by vaccination ("efficacy"). These
            efficacy tests are performed in volunteers who have a high risk of
            HIV infection.

PHASE I TRIALS -- DOSAGE AND SAFETY, MONOVALENT AIDSVAX B

     Phase I trials with monovalent AIDSVAX B vaccine were conducted by
Genentech. AIDSVAX B was clinically evaluated in 671 HIV-negative volunteers and
662 HIV-positive volunteers. None of the vaccinees reported serious side
effects. Some vaccinees occasionally experienced pain at the injection site, as
is common with many vaccines.

     AIDSVAX B was tested at three doses: 100 mg, 300 mg and 600 mg of gp120.
The 300 mg dose was consistently found to be most effective, stimulating a
higher antibody response without serious side effects.

     The clinical trial results also indicated that monovalent AIDSVAX B, at all
three doses tested, did not alter the progression of ongoing HIV infection. Thus
should efficacy be demonstrated in Phase III trials, we intend to apply to the
FDA for broad use of the vaccine in high-risk groups without prescreening for
HIV infection.

PHASE II TRIALS -- ANTIBODY STIMULATION, MONOVALENT AIDSVAX B

     One hundred forty HIV-negative volunteers were vaccinated and boosted three
times with monovalent AIDSVAX B vaccine. Vaccinations were given at time 0, 1
month and 6 months with an additional booster at 12 or 18 months. Antibodies
stimulated by vaccination with AIDSVAX B were measured for their ability to
neutralize HIV in culture tests. All of the vaccinated volunteers produced
antibodies in their blood that neutralized infectivity of HIV B(MN), the strain
that was used for preparation of AIDSVAX B. These neutralization tests were
considered of key importance since they measured the actual biological activity
of the vaccine-stimulated antibodies.

     Memory of the immune response to HIV in the same volunteers was measured by
examination of neutralizing antibody levels stimulated by sequential booster
shots. All vaccine recipients produced high levels of neutralizing antibody with
boosting. These antibody levels gradually declined with time. Each booster shot,
however, resulted in a rapid antibody response of even higher concentration,
demonstrating a memory recall of the antibody response. This is strong evidence
of immune memory being stimulated by the vaccine. We believe that such memory
will be key for protection, enabling the educated immune system to ward off HIV
infection before it establishes itself.

                                        8
<PAGE>   9

PHASE I/II TRIALS -- BIVALENT AIDSVAX

     We believe that, since an antibody to a single receptor-binding site can
cause neutralization, antibodies to multiple receptor-binding sites will result
in yet broader neutralization. On this basis we developed and tested two
formulations of bivalent AIDSVAX.

     We conducted two Phase I/II trials in the United States and Thailand in 214
HIV-negative volunteers. The trials used two bivalent formulations of AIDSVAX.
The volunteers were vaccinated and then given one booster one month later. The
vaccine tested in the United States was AIDSVAX B/B'. The vaccine tested in
Thailand was AIDSVAX B/E. Each of the vaccines was selected for the known
prevalence of these virus subtypes in the particular countries tested. The
trials were also designed to compare the results of bivalent AIDSVAX to those of
monovalent AIDSVAX. Four factors were monitored:

     - safety;

     - dosage;

     - antibody stimulation; and

     - production of antibodies that would neutralize strains used in bivalent
       AIDSVAX.

     The vaccine did not cause any serious side effects. Vaccinees occasionally
experienced pain at the injection site, as is common with many vaccines. In a
dose response study, the bivalent AIDSVAX demonstrated the same results as those
observed with the monovalent vaccine.

     The Phase I/II studies also demonstrated the stimulation of antibodies to
receptor-binding sites on gp120 proteins that were contained in the respective
vaccines. AIDSVAX B/B' stimulated antibodies to M-tropic and T-tropic HIV
found in the United States. AIDSVAX B/E stimulated antibodies to M-tropic and
T-tropic HIV found in Thailand. In contrast, the monovalent vaccine stimulated a
narrower range of antibodies, primarily to T-tropic strains.

     We believe these findings support our hypothesis that a combination of
gp120 proteins in the bivalent vaccine would stimulate antibodies to a broader
range of HIV strains.

PHASE III CLINICAL TRIALS FOR AIDSVAX

     In June 1996, we met with the FDA and its Vaccine and Related Biological
Products Advisory Committee to review the statistical protocol and conduct of
our North American Phase III clinical trial. At this meeting, a discussion and
vote was conducted on the issue of whether the interim analysis could be used to
determine vaccine efficacy. By a vote of 12 - 0 in favor, it was agreed
". . . that the data safety monitoring board will . . . recommend that the study
be terminated if the trial detects an efficacy of greater than 30%." In such a
case, the halt of the trial would be followed by vaccination of the placebos and
application for licensure of the vaccine.

     In May 1998, the FDA informed us that the data from our Phase I/II studies
were acceptable and that we could proceed to Phase III clinical trials
principally in North America. The first volunteers in the Phase III clinical
trial were vaccinated in June 1998.

     The Thai FDA is the governmental body involved in final approval to
manufacture and market medical products. As part of the Thai FDA review, the
Thai Ministry of Public Health has several subcommittees involved in making key
decisions. In the area of HIV/AIDS, this includes the Technical Subcommittee on
AIDS Vaccine, the Ethical Review Committee of the Research Committee, Ministry
of Public Health, and the Institutional Review Boards from the participating
institutions in the clinical trial.

     In May 1998, we outlined our plans for Phase III clinical trials in
Thailand and in February 1999, we received an import license from the Thai FDA
with approval to begin Phase III clinical trials. In March 1999, the first
volunteers in Bangkok were vaccinated, initiating the Phase III clinical trial.

                                        9
<PAGE>   10

  Trial Design

     We are currently conducting two large, placebo-controlled, double-blind,
Phase III clinical trials, one principally in North America and the other in
Thailand. A placebo-controlled, double-blind trial is one in which one group of
volunteers receives a placebo and the other group receives the experimental
vaccine, and neither the volunteers nor the clinicians knows whether a volunteer
is receiving the placebo or the experimental vaccine. The test group of
volunteers receives AIDSVAX while the placebo group receives a
comparable-appearing placebo containing alum alone. All vials of vaccine and
placebo are coded. During the trials, neither volunteers nor researchers know
which volunteers are given the vaccine or placebo until the Phase III clinical
trials are completed or stopped by the independent review board. Each volunteer
is vaccinated a total of seven times, including six boosters, during a 30-month
period. The purpose of the six boosters, one each six months, is to stimulate
high antibody levels throughout the entire trial period. During each visit, the
volunteers receive counseling on how to avoid the risk of HIV infection.
Follow-up with volunteers will continue for at least six months after the last
vaccination is administered.

     Volunteers in North America consist of HIV-negative homosexual men and
HIV-negative women who have HIV-infected sexual partners or high-risk sexual
behavior. Volunteers in Thailand consist of HIV-negative intravenous drug users
with a high risk for blood-borne transmission of HIV. In both North America and
Thailand, the volunteers are recruited, vaccinated and monitored by clinics with
HIV expertise and experience with these particular population groups.

     The size of each Phase III clinical trial was established by a statistical
model that included: (1) the probability of demonstrating 30% efficacy at
statistical significance in inhibiting HIV infection; (2) the rate of infection
of the volunteer group; and (3) assumptions concerning the rate of retention of
the volunteers in the trial for a 36 month clinical observation period.

     Within these parameters, the clinical trial in North America is designed
for 5,400 volunteers, randomized 2:1 for vaccine:placebo recipients. The trial
in Thailand is designed for 2,500 volunteers, randomized 1:1 for vaccine:placebo
recipients. The North American Phase III clinical trial is taking place in 56
clinics in the U.S., one clinic each in Puerto Rico and in The Netherlands, and
three clinics in Canada. The trial in Thailand is occurring in 17 methadone
clinics under direction of the Bangkok Metropolitan Administration.

     Each Phase III clinical trial is conducted in two overlapping steps:

          (1) recruitment of volunteers during an estimated 12 to 14 month
     period; and

          (2) a 36 month clinical observation period.

     For each individual, the 36 month observation period begins on the day of
their first vaccination. As a result, the entire clinical trial will be
completed upon recruitment of the volunteers and completion of their collective
36 month observation periods.

     As part of the study design, an interim efficacy analysis will be performed
in each clinical trial. In the Thai trial, the interim analysis will be
conducted 18 months after recruitment has been completed. In our North American
trial, the interim analysis will be conducted 24 months after recruitment has
been completed. Under the current timetable, the interim analysis for each
clinical trial will be conducted in late 2001.

  Enlistment of Clinical Sites and Volunteers

     We enlist clinical sites based on their ability to perform clinical trials,
and to recruit the appropriate type and number of volunteers for the Phase III
clinical trials. Our North American trial called for approximately 1,700
HIV-negative volunteers to be recruited from an already established group of
at-risk individuals at 12 clinical centers. These centers, currently sponsored
by the National Institutes of Health as part of a vaccine preparedness trial,
have over the past four years established a system for the recruitment of
at-risk volunteers. The trial design further called for the remaining 3,700
HIV-negative volunteers to be recruited by the 49 additional clinical sites.
Based on experience at the 12 clinical centers, we are assuming an incidence of
1.5% HIV infection per year, and a retention rate of at least 80% for volunteers
for the entire 36 month observation period.
                                       10
<PAGE>   11

     In Thailand, a group of injection drug users is being recruited through a
combined effort of the Bangkok Metropolitan Administration, Mahidol University
and the Centers for Disease Control and Prevention. The trial design calls for
an estimated 600 HIV-negative volunteers to be recruited from an already
established group and for the remaining 1,900 HIV-negative volunteers to be
recruited from injection drug users in the Bangkok population. Based on prior
experience, we are assuming a 4% incidence of HIV in these groups, with a
retention rate of over 75% during the 36 month observation period. We are
continuing to recruit to reach the goal of 2,500 volunteers for this clinical
trial.

  Conduct of the Phase III Clinical Trials

     We have a clinical team of 24 full-time employees who assist and monitor
the 61 clinical sites that are engaged in the North American AIDSVAX trials.
This clinical team organizes and monitors:

     - the clinical testing sites;

     - data management;

     - the central contract laboratory for HIV testing;

     - sample handling and shipping; and

     - bio-statistics.

     Audit and monitoring functions are conducted by an outside clinical
research organization, which audits the clinical sites for compliance with the
Phase III procedures, data recording, medical records and the use of good
clinical practice, as defined by the FDA.

     In Thailand, we have contracted a full-time staff of three. The Bangkok
operations are directed by a Thai physician and a project manager who provide
interface between us and Thai institutions involved in the Phase III clinical
trials. An additional 51 people in Thailand are involved in administration and
conduct of the trials.

     Each clinical site has agreed to conduct its activities according to the
United States and Thai FDA-reviewed Phase III protocol. The protocol sets
standard procedures for all sites and laboratories. Following each visit of
volunteers to the clinical site, data are recorded in both the volunteers'
permanent medical chart, as well as on a case report form, which is forwarded to
us. The trial design calls for over 600,000 case report forms to be gathered and
entered into the database for the North American Phase III clinical trial alone.

     The Phase III protocol also requires clinical sites to report any serious
adverse event to us within 24 hours. Any serious adverse events are to be
immediately examined in detail by our clinical monitors. If deemed a serious
event related to the vaccine, the event is to be promptly reported to the FDA.
The protocol requires all other adverse events to be recorded on the case report
forms and provided to the FDA for review on a periodic basis.

  Interim Analysis and Completion of the Phase III Clinical Trials

     A single independent data and safety monitoring board oversees the clinical
trials in North America and Thailand. The 10 person monitoring board consists of
prominent clinicians, AIDS specialists, vaccinologists and statisticians. The
board contains seven members from the United States and three from Thailand. A
former Deputy Director of the Centers for Disease Control and Prevention serves
as the Chairman of the monitoring board.

     The monitoring board will periodically evaluate the safety of the trial at
6, 12, 24 and 36 months. The initial two six-month safety reviews were conducted
in March and September 1999. No serious adverse events related to the vaccine
were observed.

     The monitoring board will conduct an interim efficacy analysis
approximately midway through the observation period of each clinical trial. If
the results of the interim analysis demonstrate 30% or greater efficacy, at
statistical significance, the monitoring board will recommend that we, and we
will, terminate the

                                       11
<PAGE>   12

trial. We will then vaccinate the placebo group in order to conform with ethical
requirements. If the interim efficacy analysis does not demonstrate sufficient
statistical power to halt the trial, it will continue until its scheduled
completion.

     Following the close of the Phase III clinical trials, either at the time of
the interim efficacy analysis or at the conclusion of the complete trial, the
code for vaccine/placebo will be released. The external statistician will
perform analysis of the database independently. In addition to examining the
data, the external statistician will prepare the final report, which will be
entered into the biologics license application.

  Determination of Efficacy

     The primary endpoint of the Phase III clinical trials will be to determine
the quantitative effect of AIDSVAX in high-risk volunteers. To gain FDA
regulatory approval for the sale of AIDSVAX in the United States, we believe,
based on discussions with the FDA and the recommendations of its Vaccine and
Related Biological Products Advisory Committee, that we will need to demonstrate
that the AIDSVAX vaccine reduces the level of HIV infection by at least 30% at a
statistically significant level. Statistical significance means that if the
clinical trial were repeated, an efficacy of greater than 30% would be observed
95 times out of 100. While these discussions and the vote of the Vaccine and
Related Biological Products Advisory Committee are not binding on the FDA, they
are generally followed. In the context of our United States clinical trial,
which represents a small sampling from the entire population, this means that in
order to establish a 30% efficacy at a statistically significant level there
must be an observed reduction in the incidence of HIV in the group receiving the
vaccine compared to the control group of between 45% to 65%, or possibly a
higher percentage, depending on various factors that will have a bearing on the
statistical significance of the clinical trial results. These factors include
the number of patients ultimately enrolled in the study, the rate of HIV
infection in the control group and the length of time associated with the
clinical observation period. We anticipate that the efficacy required to obtain
regulatory approval to market AIDSVAX in foreign countries will vary from one
country to another and may differ significantly from that required by the FDA.

     A secondary endpoint of the Phase III clinical trials will be to determine
qualitative effects of AIDSVAX on potential HIV infections. This is performed in
case the vaccine induces meaningful immunity, but the immune response is not of
sufficient strength to fully prevent infection. For this purpose, multiple blood
samples are drawn from each volunteer throughout the Phase III clinical trials.
This allows us to determine more precisely the time of infection. Each of the
blood samples also can be examined for levels of circulating virus, or viral
load. From this, we can determine if vaccinated individuals have suppressed
their HIV infections relative to those in the placebo group.

     If the infection is transient, or if the level of HIV is maintained in
vaccine recipients at low levels, this might indicate that the vaccine is
slowing the progression of HIV infection. In therapeutic studies it is known
that suppression of viral load correlates with an extension of life. Therefore,
should we find that AIDSVAX causes a qualitative reduction in HIV infection, we
might submit this data to support our primary regulatory application or, if
justified, as a stand-alone submission.

     In addition to HIV antibody testing of all blood samples, a subset of
volunteers, 5% of the total, will be monitored throughout the trial period with
a variety of immunological tests. These tests will be performed to determine
details of the immune response, with the goal of identifying an immune correlate
of protection against infection. Such a correlate might include, for example, a
determination of the minimum antibody level required to obtain protection. We
believe the finding of a correlate of protection both supports the scientific
rationale of the vaccine and provides a measurement by which the vaccine may be
improved. We believe finding a correlate of protection would be viewed favorably
in the context of any regulatory applications submitted to the FDA.

THE MARKET FOR AIDSVAX

     We have developed formulations of AIDSVAX that focus on HIV found in some
of the major regions of the world. Our first bivalent vaccine, AIDSVAX B/B',
is directed against the predominant HIV subtype in the Americas, Europe, the
Caribbean and Australia. Our second bivalent vaccine, AIDSVAX B/E, is directed
                                       12
<PAGE>   13

against the predominant HIV subtypes in Southeast Asia, the Pacific Rim,
Indonesia and southern portions of China.

     We also have plans to develop additional AIDSVAX vaccines -- for subtype C
virus, which would be directed against viruses in China, India and Africa, and
for subtype A and D viruses, which are commonly found in Sub Saharan Africa and
parts of South America. We believe that AIDSVAX vaccines directed against the A,
B, C, D and E subtypes of HIV would effectively address the worldwide spread of
the HIV/AIDS epidemic.

  Influence of Vaccine Improvements

     We believe we will be able to rapidly develop new formulations of AIDSVAX
should they be required. This would enhance our ability to address
geographically defined markets. This process provides for a continued basis of
product improvement. We have already accomplished this with our two bivalent
formulations of AIDSVAX.

     We expect successive formulations of AIDSVAX to improve product efficacy,
as well as the breadth of protection against different HIV subtypes. In
addition, we will seek to create vaccines that require fewer booster shots and
that can be used over larger areas of the world. Thus, we expect that an initial
vaccine could be gradually enhanced, resulting in corresponding increases in the
size of the market for the vaccine.

     On the basis of our ongoing discussions with the FDA, we believe that
improvements will be accomplished as amendments to our initial regulatory
license, rather than as applications for entirely new products. This approach,
if successful, would result in considerable savings of time and cost associated
with future product development.

LICENSE AND SERVICES AGREEMENTS WITH GENENTECH

     We have entered into a license agreement with Genentech, which in part
defines the working relationship between the companies. The licensed technology
relates to the development of a vaccine based on containing, incorporating or
using the recombinant gp120 subunit protein developed by Genentech to prevent,
but not treat, HIV infection and/or AIDS. Genentech has granted us an exclusive
license to all patents and patent applications directly related to this
technology and to proprietary know-how necessary for this technology. Certain
portions of the licensed technology are sublicensed to us under licenses from
third parties to Genentech. We, as the exclusive licensee of Genentech, have
assumed all of Genentech's obligations under these third-party license
agreements. The initial term of the license agreement is 15 years from the
commercial introduction date of a licensed product and will be determined on a
country-by-country, product-by-product basis.

     Genentech has an option to obtain an exclusive worldwide license to use,
market and sell licensed products. This option is exercisable for 90 days after
we make our first filing with the FDA for marketing approval of a licensed
product. If Genentech exercises the marketing option:

     - Genentech is required to pay us a fee equal to 33% of our total
       development costs including clinical testing, to date for the licensed
       product;

     - we and Genentech will share net profits from sales of the licensed
       products, 30% and 70%, respectively, for sales within the United States
       and 70% and 30%, respectively, for sales outside the United States;

     - future developmental costs will be apportioned between the parties based
       on their respective profit share in a particular country; and

     - the parties will establish a committee with an equal number of
       representatives from each company to oversee the development and
       commercialization of additional licensed products.

     While the agreement specifies the formula used to calculate net profits,
the calculation of individual components of the formula are subject to future
negotiations and/or determination.

                                       13
<PAGE>   14

     In the event that Genentech does not exercise the marketing option, then,
in lieu of sharing net profits from the licensed products, we will pay Genentech
a royalty on all sales of licensed products equal to:

     - 25% of our net sales and our sublicensees' net sales of the licensed
       products worldwide, so long as any commercial vaccine component has been
       manufactured and supplied by Genentech; or otherwise

     - 15% of our total net sales and our sublicensees' net sales of the
       licensed products worldwide.

     Under the license agreement, we are required to use due diligence in
developing, seeking regulatory approval for, marketing and commercializing
licensed products. Development and commercialization of licensed products will
be our sole business goal. In connection with reaching this goal, we are
required to achieve the filing of the first market approval for a licensed
product with the FDA no later than the fifth anniversary of the closing of our
1997 private placement. If we are unable to meet this milestone due to certain
agreed-upon events or circumstances, we may request an extension from Genentech
and Genentech and we can agree to a new date for the milestone, subject to a
two-year limit on such extensions. If we are unable to meet a milestone for any
reason other than the agreed-upon events or circumstances, any extension granted
will be at Genentech's sole discretion. If we fail to exercise our due
diligence, Genentech has the right to convert our exclusive license to a
non-exclusive license, and may be entitled to terminate the license.

     Either party may terminate the license agreement upon the other party's
default or bankruptcy. In addition, Genentech may terminate the license
agreement if we fail to:

     - maintain a tangible net worth of at least $1 million; or

     - meet a due diligence milestone within two years of the date originally
       set for such milestone, unless Genentech waives such two-year limit in
       its sole discretion.

     Genentech supplied us, cost-free, with its stock of approximately 300,000
doses of the B(MN) gp120 protein for testing in our Phase III clinical trials.
We will use the B(MN) gp120 protein following successful completion of
formulation with alum, vialing and quality assurance/control testing, for which
we will bear Genentech's costs and expenses. Genentech also supplied us with
agreed-upon amounts of up to two additional gp120 proteins, B(GNE8) and E(244)
for use in combination with the currently manufactured B(MN) gp120 for clinical
trials. For the additional antigens, we paid Genentech its fully burdened
manufacturing costs.

     The license agreement provides for flexibility related to manufacturing.
Should Genentech elect not to manufacture any vaccine supplies beyond those it
has already agreed to supply, we may elect to use a third party for our
manufacturing and marketing requirements. If we utilize a third party, Genentech
must transfer the required manufacturing technology and know-how to the third
party.

     We have also entered into a services agreement with Genentech pursuant to
which Genentech has agreed to provide us with administrative, research, process
science, manufacturing, clinical and regulatory support, primarily by making the
services of certain Genentech personnel available to us. We reimburse Genentech
for all of Genentech's costs and expenses relating to the provision of these
services. Either party may terminate the services agreement upon a breach, which
continues uncured for more than 60 days, or upon the occurrence of bankruptcy or
similar events. In addition, the services agreement will automatically terminate
upon any termination of the license agreement. The term of the services
agreement will expire on December 31, 2000.

LICENSED PATENTS

     Under the license agreement, we have licensed from Genentech exclusive
rights to a portfolio of United States and foreign patents. These patents cover
nine families of subject matter. We have six issued United States patents and
nine pending United States patent applications. With foreign filings, we have 82
issued patents and 38 are still pending. The technology claimed in these patents
and applications involves a range of HIV vaccine product development activities,
including the cloning and expression of recombinant virus glycoproteins for use
as vaccine products and sustained release formulations of HIV gp120. Also
claimed by patent filings are specific compositions of matter for the components
of our vaccine products, and proprietary production, recovery and purification
process technology. Together, these filings provide intellectual property that
we believe will enhance the value of our products.
                                       14
<PAGE>   15

     Under the license agreement, Genentech has retained title to the licensed
patents and patent applications and other licensed technology previously owned
by Genentech, while we will retain title to any improvements developed by us.
Both parties will jointly own any improvements to the licensed patents and
patent applications or other licensed technology developed or invented jointly.
If Genentech exercises its marketing option under the license agreement,
Genentech will have a fully paid-up, non-exclusive, worldwide license under all
improvements to the licensed know-how or patent rights that we own. Furthermore,
Genentech will have such a license if Genentech terminates the license agreement
before the expiration of the 15-year term or if we voluntarily terminate the
license agreement. Genentech will remain responsible for the filing, prosecution
and maintenance of all licensed patent rights, in consultation with us, at our
expense.

     We have been informed that Chiron Corporation has filed oppositions against
two of Genentech's European patents that are licensed to us. Genentech, with our
assistance, has filed responses to both oppositions, but the outcome of each
opposition has yet to be determined. We have also been informed by the United
States Department of Health that we may need to obtain a license under one or
more of its United States and foreign patents involving molecular clones of
HIV-1 viral strains MN-STI and BA-L. We are currently exploring the advisability
of obtaining such a license. In the interim, we have filed an opposition to a
European equivalent of the United States Department of Health patent and are
awaiting the outcome of the opposition.

SALES AND MARKETING

     We intend to rely on third parties for sales and marketing of AIDSVAX.
Genentech currently has an option to obtain an exclusive worldwide license to
use, market and sell AIDSVAX. If AIDSVAX is approved for sale and Genentech does
not exercise its option to market AIDSVAX, we intend to enter into agreements
for marketing and distribution with other partners and will pay a predetermined
royalty to Genentech.

MANUFACTURING

     We intend to rely on third parties to manufacture AIDSVAX. Our license
agreement with Genentech gives Genentech an option to manufacture and supply
AIDSVAX for clinical testing and commercial sale. The license also gives
Genentech an option to manufacture any AIDSVAX formulation beyond those it has
already agreed to supply. If Genentech does not exercise its option to
manufacture AIDSVAX, the license agreement allows us to enter into manufacturing
agreements with third parties and pay a predetermined royalty to Genentech. If
we utilize a third party, the license agreement provides that Genentech must
transfer the required manufacturing technology and know-how to the third party.

     Genentech has developed a proprietary method for producing synthetic gp120
protein. This method has enabled Genentech to clone and express gp120 genes from
two dozen HIV strains. Utilizing genetic engineering, a fragment of coding
information from HIV, consisting of the gp120 gene, is cloned from HIV into
mammalian cells. We have an exclusive license from Genentech to all of these
genes and the technical know-how to produce the synthetic gp120 proteins.

GOVERNMENT COLLABORATIONS

     We have established collaborative relationships with two federal government
agencies: 1) The Centers for Disease Control and Prevention; and (2) National
Institute of Allergy and Infectious Diseases.

     Our collaboration with the Centers for Disease Control and Prevention (CDC)
is conducted in both the United States and Thailand. In the United States, the
CDC will support research at six of the 56 clinics in the United States
currently conducting Phase III clinical trials of our AIDSVAX vaccine. The
participating sites will continue to implement our Phase III protocol, as well
as conduct epidemiological, social and behavioral research, which will be shared
by the CDC and us. The sites will be compensated directly by the CDC for the
clinical costs, which would have been incurred by us, and for conducting the
additional research. The CDC has agreed to contribute $8,000,000 over a four
year period. In Thailand, the Centers for Disease Control are assisting in the
measurement of viral loads in vaccinees and placebos, as well as examining HIV
subtypes and strains in the at-risk population.
                                       15
<PAGE>   16

     The National Institute of Allergy and Infectious Diseases is forming a
collaboration with us to obtain and store clinical specimens from our North
American Phase III clinical trial. The proposal provides that it would fund
$4,600,000 for this program. In the event we cannot obtain certain critical
intellectual property rights, we may not be able to proceed with this
collaboration. We also have an ongoing collaboration with the HIV Vaccine Trials
Network, a clinical consortium financed by the National Institute of Allergy and
Infectious Disease. In this collaboration we will provide AIDSVAX to clinical
sites for Phase I/II clinical trials of new combination vaccines.

RELATIONSHIP WITH AVENTIS PASTEUR

     Although our non-binding letter of intent with Aventis Pasteur expired
during the fourth quarter of 1999, we continue to work with them to co-develop
an alternative vaccine regimen, called a prime/boost. The prime/boost utilizes
two independent vaccines, administered sequentially. An Aventis Pasteur vaccine
would be administered initially, the prime, followed by one of our gp120
bivalent vaccines, the boost.

     We are currently working with Aventis Pasteur to jointly supply vaccine to
the AIDS Vaccine Evaluation Group (AVEG) to conduct a phase II clinical trial,
which will evaluate the immunogenicity and safety of a combined vaccine regimen.
Additionally, we are in discussions to jointly supply vaccine with Aventis
Pasteur to the HIV Vaccine Trial Network (VTN) to conduct a phase III efficacy
trial of a similar combination vaccine regimen. The phase II clinical trial is
currently scheduled to begin during the second quarter of 2000. Whereas phase
III clinical trial, depending on the enrollment of the phase II trial, will
begin at the earliest during the latter half of 2001. Both AVEG and the VTN are
National Institutes of Health-sponsored organizations.

     Genentech holds exclusive options for the manufacturing and marketing of
AIDSVAX. In the event our agreement to supply vaccine with Aventis Pasteur has
certain conflicts with our license agreement with Genentech, they will require
resolution between Genentech and us before we can enter into a final agreement
with Aventis Pasteur.

COMPETITION

     We estimate that approximately 30 other companies have been engaged in
research to produce an HIV vaccine; most of them to date have been unsuccessful.
Only AIDSVAX and one other vaccine (Aventis Pasteur) have progressed to Phase II
testing. AIDSVAX is the only HIV vaccine to commence Phase III clinical trials.

     We believe that we now lead all competitors worldwide in the development of
an HIV preventive vaccine. Of the two HIV vaccines that have reached human
clinical trials, we have full control of the leading product, AIDSVAX, and we
plan to become a partner in the second with Aventis Pasteur.

GOVERNMENT REGULATION

     AIDSVAX is subject to federal regulation, by the federal government,
principally by the FDA under the Public Health Services Act, the Food, Drug and
Cosmetic Act and other laws, and by state and local governments. Such
regulations govern or influence, among other things, the testing, manufacture,
safety and efficacy requirements, labeling, storage, record keeping, licensing,
advertising, promotion, distribution and export of such products.

     AIDSVAX is classified by the FDA as a biological drug product. The steps
ordinarily required before a biological drug product may be marketed in the
United States include:

     - preclinical laboratory and animal testing;

     - the submission to the FDA of an Investigational New Drug Application,
       which must become effective before clinical trials may commence;

     - adequate and well-controlled clinical trials to establish the safety,
       purity and potency of the biological drug product and to characterize how
       it behaves in the human body;
                                       16
<PAGE>   17

     - the submission to the FDA of a biologics license application;

     - FDA review of the biologics license application;

     - satisfactory completion of an FDA preapproval inspection of the
       manufacturing facilities; and

     - FDA approval of the license application, including approval of all
       product labeling.

     In connection with obtaining approval to proceed with Phase III clinical
trials and in determining the trial protocol, VaxGen has met with the FDA and
its Vaccines and Related Biological Product Advisory Committee of the FDA. The
FDA's advisory committees are composed of outside experts who assist the FDA in
product reviews and provide advice on various issues. While the recommendations
of these committees are not binding on the FDA, they are commonly followed. In
connection with the Phase III clinical trials the FDA sought and received advice
from the Vaccines and Related Biological Products Advisory Committee regarding
the clinical development program and clinical study designs for AIDSVAX.

     Preclinical testing includes laboratory evaluation of product chemistry,
formulation and stability, as well as animal studies to assess the potential
safety, purity and potency of each product. Preclinical safety tests must be
conducted by laboratories that comply with FDA regulations regarding Good
Laboratory Practices. The results of the preclinical tests together with
manufacturing information and analytical data are submitted to the FDA as part
of the Investigational New Drug Application and are reviewed by the FDA before
the commencement of clinical trials. Unless the FDA objects to an
Investigational New Drug Application by placing the study on clinical hold, the
Investigational New Drug Application will become effective 30 days following its
receipt by the FDA. The FDA may suspend clinical trials at any time on various
grounds, including a finding that patients are being exposed to unacceptable
health risks. If the FDA does place the study on clinical hold, the sponsor must
usually resolve all of the FDA's concerns before the study can proceed.

     Clinical trials involve the administration of the investigational product
to humans under the supervision of qualified principal investigators. Clinical
trials are conducted in accordance with Good Clinical Practices under protocols
submitted to the FDA as part of the Investigational New Drug Application. In
addition, each clinical trial is approved and conducted under the auspices of an
institutional review board and with the patients' informed consent. The
institutional review board will consider, among other things, ethical factors,
the safety of human subjects and possibility of liability of the institutions
conducting the trial.

     Clinical trials are conducted in three sequential phases; however, the
phases may overlap. The goal of a Phase I clinical trial is to establish initial
data about safety and tolerance of the biological agent in humans. In Phase II
clinical trials, evidence is sought about the desired immune response of a
biological agent in a limited number of patients. Additional safety data and
dosing regimen information are also gathered from these studies. The Phase III
clinical trial program consists of expanded, large-scale, multi-center studies
of persons who are susceptible to the targeted disease. The goal of these
studies is to obtain sufficient evidence of the safety, purity and potency of
the proposed product. Our Phase III clinical trials of AIDSVAX are being
conducted on persons at risk for HIV infection but who test HIV negative prior
to enrollment in the trial. The FDA also frequently requests that sponsors
conduct Phase IV studies after licensing to gain additional information about
the biological drug product in a wider population.

     All data obtained from this comprehensive program, in addition to detailed
information on the manufacture and composition of the product, are submitted in
a biologics license application to the FDA for review and approval for the
manufacture, marketing and commercial shipments of AIDSVAX. FDA approval of the
biologics license application is required before marketing may begin in the
United States. The FDA also may, at any time, require the submission of product
samples and testing protocols for lot-by-lot confirmatory testing by the FDA
prior to commercial distribution. This means a specific lot of vaccine cannot be
released for commercial distribution until the FDA has authorized such release.
Similar types of regulatory processes will be encountered as efforts are made to
market the vaccine internationally. We will be required to assure product
performance and manufacturing processes from one country to another.

                                       17
<PAGE>   18

     For commercialization of AIDSVAX, the manufacturing processes described in
our biologics license application must receive FDA approval and the
manufacturing facility must successfully pass an inspection prior to approval of
AIDSVAX for sale within the United States. The pre-approved inspection assesses
whether, for example, the facility complies with the FDA's Good Manufacturing
Practices. These practices include elaborate testing, control, documentation,
record keeping and other quality assurance procedures. If Genentech does not
exercise its option to manufacture AIDSVAX, we must pursue third party
manufacturing arrangements. For marketing outside the United States, we will be
subject to the regulatory requirements of other countries, which vary from
country to country, including marketing approval requirements. The regulatory
approval process in other countries includes requirements, which vary from
country to country, and the time needed to secure approval may be longer or
shorter from that required for FDA approval.

EMPLOYEES

     As of December 31, 1999, we had 59 employees: 27 are clinical staff, 13 are
research and development staff and 19 are management/administration staff. None
of our employees is subject to a collective bargaining agreement, and we believe
that our relations with our employees are good.

                        FACTORS AFFECTING FUTURE RESULTS

     This section briefly discusses certain risks that should be considered by
stockholders and prospective investors in VaxGen. You should carefully consider
the risks described below, together with all other information included in this
Annual Report on Form 10-K and the information incorporated by reference in this
Annual Report on Form 10-K. If any of the following risks actually occur, our
business, financial condition or operating results could be harmed. In such
case, the trading price of our common stock could decline.

     This Annual Report on Form 10-K also contains forward-looking statements
that involve risks and uncertainties. Our actual results could differ materially
from those anticipated in the forward-looking statements as a result of factors
that are described below and elsewhere in this Annual Report on Form 10-K. When
used in this discussion, the words "intend," "anticipate," "believe,"
"estimate," "plan" and "expect" and similar expressions as they relate to us are
included to identify forward-looking statements. Such statements are subject to
certain risks and uncertainties that could cause actual results to differ
materially from those projected. Readers are cautioned not to place undue
reliance on such forward-looking statements, which speak only as of the date
hereof. The Company undertakes no obligation to publicly release the results of
any revisions to such forward-looking statements that may be made to reflect
events or circumstances after the date hereof or to reflect the occurrence of
unanticipated events.

     IF WE ARE UNABLE TO COMMERCIALIZE OUR SOLE PRODUCT CANDIDATE, AIDSVAX, WE
MAY NOT HAVE REVENUES TO CONTINUE OPERATIONS. AIDSVAX is our only product
candidate. We do not know whether the current or planned formulations of AIDSVAX
will be effective in preventing HIV infection. The overall scientific knowledge
of HIV is limited. Although our research has indicated that AIDSVAX contains a
protein that is critical in the infection process, other proteins may be
necessary to develop an effective vaccine.

     Our success will depend entirely on the success of AIDSVAX. In particular,
we must be able to:

     - establish the safety, purity and potency of AIDSVAX in humans;

     - obtain regulatory approvals for AIDSVAX, including a preapproval
       inspection of the manufacturing facility; and

     - successfully commercialize AIDSVAX through collaborative relationships.

     If we are unable to commercialize AIDSVAX, we do not have other products
from which to derive revenue.

     IF WE ARE NOT ABLE TO DEMONSTRATE THE EFFICACY OF AIDSVAX IN OUR CLINICAL
TRIALS OR OUR CLINICAL TRIALS ARE DELAYED, WE MAY NOT BE ABLE TO OBTAIN
REGULATORY CLEARANCE TO MARKET AIDSVAX IN THE UNITED STATES OR ABROAD ON A
TIMELY BASIS, OR AT ALL. Clinical testing is a long, expensive and uncertain
process. We cannot assure you that the data collected from our clinical trials
will be sufficient to support approval of AIDSVAX by the FDA or any foreign
regulatory authorities, that the clinical trials will be completed on schedule
or, even if the

                                       20
<PAGE>   21

clinical trials are successfully completed and on schedule, that the FDA or any
foreign regulatory authorities will ultimately approve AIDSVAX for commercial
sale.

     To gain FDA regulatory approval for the sale of AIDSVAX in the United
States, we believe, based on discussions with the FDA and the vote of its
Vaccine and Related Biological Products Advisory Committee, that we will need to
demonstrate that the AIDSVAX vaccine reduces the level of HIV infection by at
least 30% at a statistically significant level. These discussions and the vote
of the Vaccine and Related Biological Products Advisory Committee, however, are
not binding on the FDA. In the context of our United States clinical trial,
which represents a small sampling from the entire population, this means that in
order to establish 30% efficacy at a statistically significant level there must
be an observed reduction in the incidence of HIV in the group receiving the
vaccine compared to the control group of between 45% to 65%, or possibly a
higher percentage, depending on various factors that will have a bearing on the
statistical significance of the clinical trial results. These factors include
the number of patients ultimately enrolled in the study, the rate of HIV
infection in the control group and the length of time associated with the
clinical observation period. We anticipate that the efficacy required to obtain
regulatory approval to market AIDSVAX in foreign countries will vary from one
country to another and may differ significantly from that required by the FDA.
We cannot assure you that the data collected from our United States or Thai
clinical studies will demonstrate the required level of efficacy to permit the
commercialization of AIDSVAX in the United States, in Thailand or in any other
foreign country.

     Our trials could be delayed for a variety of reasons, including:

     - delays in enrolling volunteers;

     - lower than anticipated retention rate of volunteers in the trial; or

     - serious adverse events related to the vaccine.

     Results of previous animal trials may not be relevant for determining the
protective effect of AIDSVAX against HIV infection in humans. Preclinical and
clinical data can be interpreted in different ways, which could delay, limit or
prevent regulatory approval. Serious adverse events related to the vaccine
during our Phase III clinical trials could cause the trials to be prematurely
terminated. Negative or inconclusive results could cause the trials to be
unacceptable for submission to regulatory authorities.

     IF WE FAIL TO COMPLY WITH EXTENSIVE REGULATIONS ENFORCED BY DOMESTIC AND
FOREIGN REGULATORY AUTHORITIES, THE COMMERCIALIZATION OF AIDSVAX COULD BE
PREVENTED OR DELAYED. AIDSVAX is subject to extensive government regulations
related to development, clinical trials, manufacturing and commercialization.
The process of obtaining FDA and other regulatory approvals is costly, time
consuming, uncertain and subject to unanticipated delays.

     The FDA may refuse to approve an application if it believes that applicable
regulatory criteria are not satisfied. The FDA may also require additional
testing for safety and efficacy. Moreover, if regulatory approval of a product
is granted, the approval may be limited to specific indications or limited with
respect to its distribution. For instance, the FDA may approve the licenses for
only high-risk populations. Foreign regulatory authorities may apply similar
limitations or may refuse to grant any approval.

     There can be no assurance that the FDA will approve the AIDSVAX
manufacturing processes or that manufacturing facilities will pass an FDA
preapproval inspection for AIDSVAX. Should Genentech elect not to manufacture
AIDSVAX, we must secure a third party manufacturer. We cannot assure you that we
will successfully identify a third party manufacturer or that its facilities
will pass an FDA preapproval inspection for AIDSVAX. At a minimum, the FDA will
require equivalence testing between Genentech produced AIDSVAX and third party
produced AIDSVAX. Depending upon differences in manufacturing processes, the FDA
may also require additional clinical studies to establish the safety, purity and
potency of AIDSVAX. Any failure to obtain or delay in obtaining such approvals
would have a material adverse effect on our business, financial condition and
results of operation.

     Even after United States regulatory approval for AIDSVAX is obtained, the
license will be subject to continual review, and newly discovered or developed
safety or efficacy data may result in revocation of the
                                       21
<PAGE>   22

marketing license. Moreover, if and when such approval is obtained, the
marketing of AIDSVAX will be subject to extensive regulatory requirements
administered by the FDA and other regulatory bodies, including adverse event
reporting requirements and the FDA's general prohibition against promoting
products for unapproved or "off-label" uses. The AIDSVAX manufacturing
facilities are also subject to continual review and periodic inspection and
approval of manufacturing modifications. Domestic manufacturing facilities are
subject to biennial inspections by the FDA and must comply with the FDA's Good
Manufacturing Practices regulations. In complying with these regulations,
manufacturers must spend funds, time and effort in the areas of production,
record keeping, personnel and quality control to ensure full technical
compliance. The FDA stringently applies regulatory standards for manufacturing.
Failure to comply with any of these post approval requirements can, among other
things, result in warning letters, product seizures, recalls, fines,
injunctions, suspensions or revocations of marketing licenses, operating
restrictions and criminal prosecutions. Any such enforcement action could harm
our business. Unanticipated changes in existing regulatory requirements or the
adoption of new requirements could also have a material adverse effect on
VaxGen.

     We plan to pursue marketing authorization in Thailand based on the results
from the Thai trial. The Thai government also has a regulatory process that we
will need to follow before we can commercialize AIDSVAX in that country. No
assurances can be given that we will obtain marketing authorization from the
Thai government.

     VaxGen and the manufacturer of AIDSVAX also are subject to numerous
federal, state and local laws relating to such matters as safe working
conditions, manufacturing practices, environmental protection, fire hazard
control and hazardous substance disposal. There can be no assurance that we will
avoid incurring significant costs to comply with such laws and regulations in
the future, or that such laws or regulations will not have a material adverse
effect on VaxGen.

     The European Union, Japan and other countries also extensively regulate
pharmaceuticals, including biological drug products. No assurance can be given
that we will be able to obtain other countries' approvals for AIDSVAX.

     WE HAVE ONLY A LIMITED OPERATING HISTORY AND WE EXPECT TO CONTINUE TO
GENERATE LOSSES. To date, we have engaged primarily in research, development and
clinical testing. At December 31, 1999, we had an accumulated deficit of
approximately $37.7 million. We sustained net losses of approximately $23.3
million in 1999, $9.2 million in 1998, $3.1 million in 1997 and $2.1 million in
1996. We expect to incur substantial losses for at least an additional four to
five years.

     IF WE NEED ADDITIONAL FUNDS, AND ARE UNABLE TO RAISE THEM, WE WOULD HAVE TO
CURTAIL OR CEASE OPERATIONS. We are reasonably certain that our existing capital
resources would not be sufficient to support our current and planned operations
through commercialization of AIDSVAX. We do not expect AIDSVAX to be
commercially available for at least three years. AIDSVAX has not received
regulatory approval for commercial sale. If taken to completion, the Phase III
clinical testing necessary before we can file an application with the FDA for
product approval will take at least 36 months from the commencement of the
clinical trial. Once the testing is completed, we will need to analyze the data
and prepare our biologics license application for submission to the FDA, which
typically takes between three and six months to be accomplished. The FDA review
process could take at least an additional six months. We anticipate that it will
take at least six months after obtaining regulatory approval for Genentech or
another third party to begin commercialization of AIDSVAX. As a result, we do
not believe that AIDSVAX will be on the market before 2003. If AIDSVAX receives
regulatory approval, we will need to obtain additional debt or equity financing,
or funds from collaborative arrangements, to support operations through
commercialization of AIDSVAX.

     We may also need to raise additional funds prior to receiving regulatory
approval for AIDSVAX if:

     - AIDSVAX is not sufficiently safe, pure and potent to commercialize in its
       current formulation;

     - our Phase III clinical trials are delayed, are not successful or are more
       costly than currently estimated;

     - commercialization of AIDSVAX is delayed for any other reason; or

     - additional trials are required.
                                       22
<PAGE>   23

We cannot assure you that we will be able to raise sufficient funds in the
future. If we are unable to raise funds when necessary, we may have to cease or
curtail operations. Our existing capital resources will not be sufficient to
support our current and planned operations through commercialization of AIDSVAX.

     WE RELY ON GENENTECH FOR THE MANUFACTURE OF AIDSVAX. OUR INABILITY TO
MANUFACTURE AIDSVAX, AND OUR DEPENDENCE ON GENENTECH, MAY DELAY OR IMPAIR OUR
ABILITY TO GENERATE REVENUES, OR ADVERSELY AFFECT OUR PROFITABILITY. We have no
manufacturing facilities. We are entirely dependent on third parties to produce
AIDSVAX. To date, we have relied on Genentech for this purpose. Genentech
currently has an exclusive option to manufacture AIDSVAX. We believe that
Genentech is the manufacturer best able to produce AIDSVAX. Our license
agreement with Genentech does not specify the price we will be required to pay
Genentech to manufacture AIDSVAX.

     If Genentech does not manufacture AIDSVAX, we will need to locate and
engage another manufacturer. The cost and time to establish manufacturing
facilities to produce AIDSVAX would be substantial. As a result, using a
manufacturer other than Genentech could delay bringing AIDSVAX to market. This
delay could require us to raise additional funds.

     We cannot assure you that we will be able to enter into an agreement with a
third party to manufacture AIDSVAX. We also have no way to determine the price
we would be charged by a third party to manufacture AIDSVAX if Genentech does
not manufacture AIDSVAX. Any manufacturer other than Genentech would have to
prove both to us and to the FDA and to other regulatory authorities that its
manufacturing process, facilities, procedures, and personnel comply with
government regulations and that it consistently produces the same product that
was made by Genentech and tested in the Phase III clinical trials. If a company
other than Genentech does manufacturing, we may have to do additional clinical
trials to show the therapeutic equivalence of the product made by the other
company to the Genentech product.

     We rely on Genentech for the sale, marketing and commercialization of
AIDSVAX. Our lack of sales and marketing personnel, and of distribution
relationships, may impair our ability to generate revenues. We have no sales,
marketing or commercialization capability. Genentech currently has an exclusive
option to market and distribute AIDSVAX. We intend to rely on Genentech to
provide an established distribution system and sales force to market AIDSVAX. If
Genentech does not elect to exercise its option to market and distribute the
product, we will need to locate and engage another partner to market and
commercialize AIDSVAX. We cannot assure you that we will be able to establish
marketing or commercialization arrangements with third parties in a timely
manner or on favorable terms.

     POLITICAL OR SOCIAL FACTORS MAY DELAY OR REDUCE REVENUES BY DELAYING OR
IMPAIRING OUR ABILITY TO MARKET AIDSVAX. Products developed for use in
addressing the HIV/AIDS epidemic have been, and will continue to be, subject to
competing and changing political and social pressures. The political and social
response to the HIV/AIDS epidemic has been highly charged and unpredictable.
These pressures can transcend national barriers. They may delay or cause
resistance to bringing our product to market or limit pricing of our product.

     IF GENENTECH TERMINATES OUR LICENSE AGREEMENT, WE MAY NOT BE ABLE TO
DEVELOP OR MARKET AIDSVAX ON COMMERCIALLY REASONABLE TERMS, OR AT ALL. We cannot
conduct our business without the technology we license from Genentech. Our
license agreement with Genentech permits Genentech to terminate the agreement,
or terminate the exclusivity of our license, if we:

     - fail to use due diligence in developing, seeking regulatory approval for,
       marketing or commercializing products covered by the Genentech license
       agreement;

     - fail to file the first market approval application for AIDSVAX with the
       FDA prior to May 2002, subject to potential extension for up to two years
       in certain circumstances, any other extension being Genentech's sole
       decision;

     - breach the license agreement and fail to cure the breach within the time
       period provided in the agreement;

                                       23
<PAGE>   24

and we are not able to cure these breaches within the period provided in the
Genentech license agreement. Genentech may also terminate the agreement at any
time if we fail to maintain a tangible net worth of at least $1 million.

     FAILURE TO RETAIN KEY MANAGEMENT EMPLOYEES COULD ADVERSELY AFFECT OUR
ABILITY TO OBTAIN FINANCING, CONDUCT CLINICAL TRIALS, OR DEVELOP AIDSVAX. We are
highly dependent on our senior management and scientific staff, particularly Dr.
Donald Francis, our President, Dr. Robert Nowinski, our Chairman and Chief
Executive Officer, and Dr. Phillip Berman, our Senior Vice President, Research &
Development. These individuals have played a critical role in developing the
vaccine, raising financing and conducting clinical trials. The loss of the
services of any of these key members of senior management may prevent us from
achieving our business objectives.

     IF WE ARE UNABLE TO PROTECT OUR INTELLECTUAL PROPERTY, WE MAY BE UNABLE TO
PREVENT OTHER COMPANIES FROM USING OUR TECHNOLOGY IN COMPETITIVE PRODUCTS. IF WE
INFRINGE THE INTELLECTUAL PROPERTY RIGHTS OF OTHERS, WE MAY BE PREVENTED FROM
DEVELOPING OR MARKETING AIDSVAX. We rely on patent and other intellectual
property protection to prevent our competitors from manufacturing and marketing
AIDSVAX. Our technology, including technology licensed from Genentech, will be
protected from unauthorized use by others only to the extent that it is covered
by valid and enforceable patents or effectively maintained as trade secrets. As
a result, our success depends on our ability, and Genentech's ability, to:

     - obtain patents;

     - protect trade secrets;

     - operate without infringing upon the proprietary rights of others; and

     - prevent others from infringing on our proprietary rights.

     We cannot be certain that our patents or patents that we license from
Genentech will be enforceable and afford protection against competitors. We
cannot assure you that our operations or technology will not infringe
intellectual property rights of others. If we infringe the intellectual property
of others, there can be no assurance that we would be able to obtain licenses to
use the technology on commercially reasonable terms or at all.

     IF WE BECOME SUBJECT TO PRODUCT LIABILITY CLAIMS, THEY MAY REDUCE DEMAND
FOR AIDSVAX OR RESULT IN DAMAGES THAT EXCEED OUR INSURANCE LIMITATION. We face
an inherent risk of exposure to product liability suits in connection with
AIDSVAX vaccines being tested in human clinical trials and products that may be
sold commercially. We may become subject to a product liability suit if AIDSVAX
causes injury, or if vaccinated individuals subsequently become infected with
HIV. Regardless of merit or eventual outcome, product liability claims may
result in decreased demand for a vaccine, injury to our reputation, withdrawal
of clinical trial volunteers and loss of revenues.

ITEM 2. PROPERTIES

     Our executive offices are located in Brisbane, California, in an office
building in which we lease approximately 16,000 square feet. The lease agreement
terminates in September 2005, and we have an option to renew for a successive
five-year period. We also lease approximately 10,000 square feet of laboratory
space in South San Francisco under a lease agreement that terminates in April
2006. We have an option to renew for a successive five-year period. We believe
that our facilities are sufficient to support our operations for at least the
next 18 months.

     In Thailand, we lease office space at Mahidol University and at Taksin
Hospital in Bangkok. We will lease this space through the duration of the Thai
Phase III clinical trials.

ITEM 3. LEGAL PROCEEDINGS

     We are not currently subject to any material legal proceedings or claims.

DIVIDEND POLICY

     The Company has not declared or paid any cash dividends on its capital
stock since its inception. The Company currently intends to retain all of its
cash and any future earnings to finance the growth and development of its
business and therefore does not anticipate paying any cash dividends in the
foreseeable future. Any future determination to pay cash dividends will be at
the discretion of the Board of Directors and will be dependent upon the
Company's financial condition, results of operations, capital requirements and
such other factors as the Board of Directors deems relevant.

USE OF PROCEEDS FROM INITIAL PUBLIC OFFERING

     The Company completed its initial public offering (the "IPO") in July 1999,
in which it issued and sold 3,565,000 shares of common stock for aggregate
proceeds to the Company of $46,345,000. The effective date of the Registration
Statement (Commission File No. 333-78065) was June 29, 1999. The offering was
lead-managed by Prudential Securities and co-managed by Punk Ziegel & Company.
Of the aggregate proceeds received in the IPO, $4,373,000 was used to pay costs
and expenses related to the IPO, resulting in net proceeds of approximately
$42,000,000. The Company has invested the entire net proceeds from the offering
in short-term investments such as commercial paper, government obligations and
high quality corporate debt instruments. The Company has not used any of the net
offering proceeds for construction of plant, building or facilities, purchases
of real estate, acquisition of other businesses or repayment of indebtedness.

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

     This discussion and analysis should be read in conjunction with our
financial statements and related notes thereto appearing in Item 8 of this
report. In addition to historical information, this report contains "forward-
looking statements" that are within the safe harbor provisions of the Private
Securities Litigation Reform Act of 1995, and that are subject to certain risks
and uncertainties that could cause actual results to differ materially from
those projected. The words "believe", "expect", "intend", "anticipate", and
similar expressions are used to identify forward-looking statements, but their
absence does not mean that such statement is not forward-looking. Many factors
could affect the Company's actual results, including those factors described
under "Factors Affecting Future Results" and "Business." These factors, among
others, could cause results to differ materially from those presently
anticipated by the Company. 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 anticipated events.

OVERVIEW

     In November 1995, VaxGen was formed to continue development of AIDSVAX in
partnership with Genentech. In connection with our formation, Genentech licensed
to us the technology necessary for completing development and commercialization
of AIDSVAX.

     Since our formation, we have focused on developing and testing AIDSVAX. We
have developed formulations of AIDSVAX, which focus on the predominant HIV
subtype in the Americas, Europe, the Caribbean, and Australia (subtype B) and
the predominant HIV subtype in Southeast Asia and Pacific Rim countries (subtype
E). We have commenced two Phase III clinical trials, one principally in North
America and one in Thailand to determine the efficacy of AIDSVAX. We recently
completed the initial inoculation and enrollment of over 5,400 trial volunteers
for the North American Phase III clinical trial, which is being conducted in 61
clinical centers. The Thai Phase III clinical trial is being conducted in 17
clinical centers in Bangkok and is designed for 2,500 trial volunteers.

     To date, we have generated no operating revenues. We anticipate only modest
revenues from government or other grants or from collaborations with other
entities over the next three to five years. We have incurred losses since
inception as a result of research and development and general and administrative
expenses in support of our operations. As of December 31, 1999, we had a deficit
accumulated during the development stage of $37,669,000. We anticipate incurring
substantial losses over at least the next four to five years as we complete our
clinical trials, apply for regulatory approvals, continue development of our
technology and expand our operations.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1999 COMPARED TO THE YEAR ENDED DECEMBER 31, 1998

  Research and development expense

     Research and development expense increased 164% from $6,831,000 for 1998 to
$18,003,000 for 1999. The increase in research and development expenses was due
primarily to the ramping up of our North American and Thai Phase III clinical
trials. These expenses consisted principally of the cost for additional
personnel, recruiting costs for the enrollment of the clinical trials, non-cash
compensation expense related to vesting of stock options, the establishment of a
new research laboratory facility, and increases in the fees paid to third
parties associated with conducting the clinical trials.

                                       27
<PAGE>   28

  General and administrative expense

     General and administrative expense increased 124% from $3,345,000 for 1998
to $7,479,000 for 1999. The increase in general and administrative expenses was
due primarily to non-cash compensation expense for the issuance of warrants and
modification of the terms of options in connection with separation agreements
with two former employees, salaries and benefits associated with additional
personnel hired to support the growing infrastructure, and costs associated with
maintaining larger office facilities.

  Total other income (expense), net

     Other income (expense), net, consisting primarily of interest income,
increased 112% from $1,013,000 for 1998 to $2,148,000 for 1999. This was
primarily attributable to higher average balances of cash, cash equivalents and
investment securities, as a result of the initial public offering and the
private placement with Vulcan Ventures, Inc. (See further discussion in
"Liquidity and Capital Resources").

YEAR ENDED DECEMBER 31, 1998 COMPARED TO YEAR ENDED DECEMBER 31, 1997

     Our activities in 1998 were focused on preparing for and commencing our
Phase III clinical trials of AIDSVAX, developing data management systems,
continuing research and development of AIDSVAX, and private financing
activities.

  Research and development expense

     Research and development expense increased 117% from $3,146,000 in 1997 to
$6,831,000 in 1998. This increase was primarily due to additional personnel,
retaining consultants and contracting with clinics to facilitate the North
American Phase III clinical trial that began in June 1998. The increase was
partially offset by decreased vaccine production costs, as no vaccine production
was required in 1998.

  General and administrative expense

     General and administrative expense increased 318% from $800,000 in 1997 to
$3,345,000 in 1998. This increase was primarily due to an additional $900,000 in
costs associated with efforts to increase public awareness of the North American
Phase III clinical trial, an additional $800,000 in compensation expense
associated with additional personnel and, an additional $345,000 in higher rent
and related insurance costs associated with our move to larger facilities in
September 1998.

  Total other income (expense), net

     Other income (expense), net, consisting primarily of interest income
increased 14% from $886,000 in 1997 to $1,013,000 in 1998. This increase was due
to higher average balances of cash, cash equivalents, and investment securities
throughout the year resulting from our private placement completed in May 1997.

LIQUIDITY AND CAPITAL RESOURCES

     Cash, cash equivalents and investment securities were $70,534,000 at
December 31, 1999. We have financed our operations since inception through
capital provided by Genentech and sales of our common stock. Genentech has no
obligation to provide future funding to the Company.

     The Company completed its initial public offering ("IPO") in July 1999, in
which it issued and sold 3,565,000 shares of common stock for aggregate proceeds
to the Company of $46,345,000. Of the aggregate proceeds received in the IPO,
approximately $4,400,000 was used to pay costs and expenses related to the IPO,
resulting in net proceeds of approximately $42,000,000. The Company has invested
the entire net proceeds from the offering in short-term investments such as
commercial paper, government obligations and high-quality corporate debt
instruments. In early 1999, we received net proceeds of $5,273,000 from private
placement financing activities, all of which were completed prior to the IPO. In
December 1999, the Company completed a private placement of common stock with
Vulcan Ventures, Inc. This will enable the Company to commence development of
AIDSVAX vaccines designed to prevent infection by the other known major
                                       28
<PAGE>   29

subtypes of HIV, including those found in Africa, China, India and South
America. Currently, the Company has developed formulations of AIDSVAX, which
focus on the predominant HIV type in the Americas, Europe, the Caribbean, and
Australia (subtype B) and the predominant HIV subtype in Southeast Asia and
Pacific Rim countries (subtype E). Vulcan Ventures, Inc., is the investment
organization of Paul G. Allen, Chairman of Vulcan and co-founder of Microsoft
Corporation. The private placement consisted of approximately 2,174,000 shares
of common stock at $11.50 per share, which resulted in proceeds, net of
commissions and private placement expenses, to the Company of approximately
$24,000,000.

     Since our inception, investing activities, other than purchases and sales
of investment securities, have consisted entirely of equipment acquisitions and
leasehold improvements. From inception through December 31, 1999, our investment
in equipment and leasehold improvements was $3,298,000. The increase in
equipment and leasehold improvements has been primarily due to the development
of our research and development laboratory and the establishment of larger
office facility. Net cash used in operating activities for 1999 was $19,153,000
representing expenditures for research and development costs and general and
administrative expenses.

     VaxGen and the federal Centers for Disease Control and Prevention (CDC)
entered into a collaboration to support research at six of the 56 clinics in the
United States currently conducting Phase III clinical trials of our AIDSVAX
vaccine. The CDC selected the six sites in the fourth quarter of 1999.
Contractual arrangements between the CDC and the clinics have been completed
with five of the sites, with the remaining one still pending. The participating
sites will continue to implement our Phase III protocol, as well as conduct
epidemiological, social and behavioral research, which will be shared by VaxGen
and the CDC. The sites will be compensated directly by the CDC for the clinical
costs, which would have been incurred by VaxGen, and for conducting the
additional research. The CDC has agreed to contribute $8,000,000 over a four
year period.

     The National Institute of Allergy and Infectious Diseases is forming a
collaboration with us to obtain and store clinical specimens from our North
American Phase III clinical trial. The proposal provides that it would fund
$4,600,000 for this program. In the event we cannot obtain certain critical
intellectual property rights, we may not be able to proceed with this
collaboration.

     We believe that our existing cash and cash equivalents, investment
securities and investment income, will enable us to meet our forecasted
expenditures through the anticipated completion of our current Phase III
clinical trials, which is scheduled to occur at the end of 2002. We will need to
raise additional capital to finance commercialization of AIDSVAX, or to continue
operations if the Phase III clinical trials are not successful, are delayed or
more costly than currently anticipated, or if commercialization is delayed for
any other reason. We cannot assure you that we will be able to raise sufficient
funds when needed, or that such funds will be available on favorable terms.

     At December 31, 1999, we had net operating loss carryforwards of
approximately $35,100,000 to offset any future federal taxable income. If not
utilized, the net operating loss carryforwards will begin to expire in 2010. We
also had research and experimentation tax credit carryforwards at December 31,
1999, of approximately $941,000 for federal income tax purposes.

YEAR 2000 COMPLIANCE

     We did not experience any difficulties related to the Year 2000 problem on
January 1, 2000 and are not aware of any such difficulties since that date. Our
operations have not, to date, been adversely affected by any difficulties
experienced by any of our suppliers in connection with the Year 2000 problem. We
also addressed issues related to the date February 29, 2000, and management will
continue to monitor our systems for potential difficulties for the remainder of
calendar year 2000.

     Because we have been in business for a relatively short time, our exposure
to the Year 2000 issue was limited in comparison to more established companies.
However, while no such occurrence has developed as of the date of this filing to
the Company's knowledge, Year 2000 issues that may arise related to material
third parties may not be apparent immediately and therefore, there is no
assurance that the Company will not be affected by future disruptions. We do not
anticipate incurring material expenses or experiencing any material

                                       29
<PAGE>   30

disruptions as a result of any Year 2000 issues. As of the date of this filing,
the total cost of addressing any Year 2000 problems was less than $5,000. Based
on the web site information published by Genentech, our only material third
party supplier, we do not believe that their Year 2000 compliance will have a
material adverse effect on us.

MARKET RISK

     Our exposure to market rate changes are related primarily to our debt
securities included in our investment portfolio. We do not have any derivative
financial instruments. By policy, we invest in debt instruments of the U. S.
Government and high-quality corporate issuers, limit the amount of credit
exposure to any one issuer, limit duration by restricting the term, and hold
investments to maturity except under rare circumstances. Investments in both
fixed rate and floating rate interest earning instruments carry a degree of
interest rate risk. Fixed rate securities may have their fair market value
adversely impacted due to a rise in interest rates, while floating rate
securities may produce less income than expected if interest rates fall. Due in
part to these factors, our future investment income may fall short of
expectations due to changes in interest rates or we may suffer losses in
principal if forced to sell securities, which have declined in market value due
to changes in interest rates. At December 31, 1999, we held government debt
instruments with a fair value of $19,221,000. If market interest rates were to
increase immediately and uniformly by 10% from levels at December 31, 1999, the
fair value of our portfolio would decline by an immaterial amount. Our exposure
to losses as a result of interest rate changes is managed through investing
primarily in securities that mature in a period of one year or less.

     Our exposure to foreign exchange rate risk is primarily related to our
conducting clinical trials in Thailand. Thailand is currently considered an
emerging economy. A sudden decrease in Thailand's currency exchange rate versus
the U.S. Dollar could have an adverse impact on our expenses. The majority of
our contracts associated with conducting clinical trials in Thailand are priced
in Baht. At the time these contracts were written, the Thailand exchange rate
was 37.5 Baht per one U. S. Dollar. As of December 31, 1999, we have incurred
$25,000 in foreign exchange losses. We are currently hedging our foreign
currency exposure in Thai Baht by purchasing forward foreign exchange contracts.
We anticipate that we will not record any material foreign exchange gains or
losses due to transactions in Thai Baht during 2000.

NEW ACCOUNTING PRONOUNCEMENTS

     In June 1998, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 133, "Accounting for Derivative
Instruments and Hedging Activities". SFAS 133 establishes a new model for
accounting for derivatives and hedging activities and supersedes and amends
existing accounting standards and is effective for fiscal years beginning after
June 15, 2000. SFAS 133 requires that all derivatives be recognized in the
balance sheet at their fair market value, and the corresponding derivative gains
or losses be either reported in the statement of operations or as a component of
other comprehensive income depending on the type of hedge relationship that
exists with respect to such derivative. We do not expect the adoption of SFAS
133 to have a material impact on our financial statements.

     In December 1999, The United States Securities and Exchange Commission
(SEC) released Staff Accounting Bulletin (SAB) No. 101 "Revenue Recognition in
Financial Statements," which must be applied in our second fiscal quarter of
2000. SAB 101 provides guidance on revenue recognition and the SEC staff's views
on the application of accounting principles to selected revenue recognition
issues. We do not expect that the adoption of SAB 101 will have a material
effect on our financial statements.

ITEM 8. Financial Statements and Supplementary Data

                          INDEPENDENT AUDITORS' REPORT

The Board of Directors and Shareholders
VaxGen, Inc.:

     We have audited the accompanying balance sheets of VaxGen, Inc. (a
development stage enterprise) as of December 31, 1999 and 1998, and the related
statements of operations, cash flows, and stockholders' equity (deficit) and
comprehensive loss for each of the years in the three-year period ended December
31, 1999 and the period from November 27, 1995 (inception) through December 31,
1999. These financial statements are the responsibility of the Company's
management. Our responsibility is to express an opinion on these financial
statements based on our audits.

     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of VaxGen, Inc. (a development
stage enterprise) as of December 31, 1999 and 1998, and the results of its
operations and its cash flows for each of the years in the three-year period
ended December 31, 1999 and the period from November 27, 1995 (inception)
through December 31, 1999, in conformity with generally accepted accounting
principles.

                         NOTES TO FINANCIAL STATEMENTS

 1. ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

  Nature of Development Stage Activities

     VaxGen, Inc. (the "Company") is a development stage biotechnology company
formed to develop a vaccine (AIDSVAX) intended to eradicate HIV. The Company was
incorporated on November 27, 1995 and since that date its principal activities
have included defining and conducting research programs, conducting animal and
human clinical trials, raising capital and recruiting scientific and management
personnel.

     The Company's development activities involve inherent risks. These risks
include, among others, dependence on key personnel and determination of
patentability of the Company's products and processes. The Company is dependent
on Genentech, Inc. ("Genentech") to provide certain research and development
support and vaccine production (Note 4). In addition, the Company has only one
product candidate, which has not yet obtained Food and Drug Administration
approval. Successful future operations depend upon the Company's ability to
obtain approval for and commercialize AIDSVAX.

  Cash Equivalents

     All short-term investments with an original maturity at date of purchase of
three months or less are considered to be cash equivalents. Cash equivalents
consisting of commercial paper amounted to $14,954,000 and $6,490,000 at
December 31, 1999 and 1998, respectively.

  Investment Securities

     Investment securities are classified as available-for-sale and carried at
market value with unrealized gains and losses excluded from the statement of
operations and reported as other comprehensive income. Realized gains and losses
on sales of investment securities are determined on the specific identification
method and are included in investment income, net.

  Property and Equipment

     Equipment, consisting of laboratory equipment, computers and other office
equipment, is depreciated using the straight-line method over the assets'
estimated useful lives of three to ten years. Leasehold improvements are
amortized using the straight-line method over the shorter of the assets'
estimated useful lives or the remaining term of the lease.

  Research and Development Costs

     Research and development costs are charged to expense as incurred.

  Income Taxes

     Deferred income taxes are provided based on the estimated future tax
effects of temporary differences between financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating
loss and tax credit carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates that are expected to apply to taxable income in
the years in which those temporary differences are expected to be recovered. The
effect on deferred tax assets and liabilities of a change in tax rates is
recognized in income in the period that includes the enactment date. A valuation
allowance is established to reduce deferred tax assets to the amount expected to
be realized.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

  Fair Value of Financial Instruments

     The Company has financial instruments other than cash and investment
securities, consisting of interest receivable, accounts payable, and a payable
to Genentech. The fair value of these financial instruments approximates their
carrying amount due to their short-term nature.

  Stock-Based Compensation

     The Company accounts for its stock option plans for employees and
non-employee members of the Board of Directors in accordance with the provisions
of Accounting Principles Board (APB) Opinion No. 25, Accounting for Stock Issued
to Employees, and related interpretations. Accordingly, compensation expense
related to employee stock options is recorded if, on the date of grant, the fair
value of the underlying stock exceeds the exercise price. The Company applies
the disclosure only requirements of Statement of Financial Accounting Standards
(SFAS) No. 123, which allows entities to continue to apply the provisions of APB
25 for transactions with employees, and to provide pro forma results of
operations disclosures for employee stock option grants as if the
fair-value-based method of accounting in SFAS 123 had been applied to these
transactions.

  Comprehensive Income (Loss)

     Comprehensive income (loss) consists of net income (loss) and other gains
and losses affecting stockholders' equity that, under generally accepted
accounting principles, are excluded from net income (loss). These include
unrealized gains or losses on available-for-sale securities.

  Loss Per Share

     Basic loss per share is computed on the basis of the weighted average
number of shares outstanding for the reporting period. Diluted loss per share is
computed on the basis of the weighted average number of common shares plus
dilutive potential common shares outstanding using the treasury stock method.
Potential dilutive common shares consist of shares issuable to holders of
unexercised employee stock options and warrants outstanding. Options and
warrants to purchase, in the aggregate, approximately 1,699,000, 751,000, and
419,000 shares of common stock outstanding at December 31, 1999, 1998 and 1997,
respectively, were not included in the calculation of diluted loss per share
because the representative share increments would be antidilutive.

  Use of Estimates

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

  Impairment of Long-Lived Assets

     The Company evaluates its long-lived assets for impairment whenever events
or changes in circumstances indicate that the carrying amount of an asset may
not be recoverable. Recoverability of assets held and used is measured by a
comparison of the carrying amount of an asset to future net cash flows expected
to be generated by the asset. If such assets are considered to be impaired, the
impairment to be recognized is measured by the amount by which the carrying
amount of the assets exceeds the discounted future cash flows expected to be

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

generated by such assets. Assets to be disposed of are reported at the lower of
their carrying amount or fair market value less costs to sell.

  Reclassifications

     Certain prior year amounts have been reclassified to conform with the 1999
presentation.

  Business Segments

     The Company's operations are confined to one business segment, the
discovery and development of vaccines that immunize against HIV.

  New Accounting Pronouncements

     In June 1998, the Financial Accounting Standards Board issued SFAS 133,
"Accounting for Derivative Instruments and Hedging Activities". SFAS 133
establishes a new model for accounting for derivatives and hedging activities
and supersedes and amends existing accounting standards and is effective for
fiscal years beginning after June 15, 2000. SFAS 133 requires that all
derivatives be recognized in the balance sheet at their fair market value, and
the corresponding derivative gains or losses be either reported in the statement
of operations or as a component of other comprehensive income depending on the
type of hedge relationship that exists with respect to such derivative. The
Company does not expect the adoption of SFAS 133 will have a material impact on
its financial statements.

     In December 1999, The United States Securities and Exchange Commission
(SEC) released Staff Accounting Bulletin (SAB) No. 101 "Revenue Recognition in
Financial Statements," which must be applied in our second fiscal quarter of
2000. SAB 101 provides guidance on revenue recognition and the SEC staff's views
on the application of accounting principles to selected revenue recognition
issues. The Company does not expect that the adoption of SAB 101 will have a
material effect on its financial statements.

4. RELATIONSHIP WITH GENENTECH

     The Company was founded in 1995 to develop and commercialize an HIV vaccine
in partnership with Genentech. In 1996, in return for an equity interest
(1,150,000 shares or 54% of the then outstanding and subscribed shares) in the
Company, rights to maintain 25% ownership of the Company's common stock (through
common stock warrants), a seat on the Board of Directors and certain
manufacturing and marketing rights to the vaccine, Genentech granted the Company
an exclusive license to certain technology.

     Genentech financed the formation of the Company by means of a $1,000,000
line of credit. Additionally, Genentech and the Company entered into an
agreement whereby Genentech could convert the line of credit plus additional
capital totaling $2,000,000 into shares of the Company's common stock concurrent
with an initial private placement in March 1997. The conversion resulted in the
issuance of 285,714 shares of common stock. Upon the final closing of the
private placement, Genentech exercised its option to retain a 25% common stock
ownership interest and thereby acquired an additional 86,640 shares of common
stock for cash. At December 31, 1998, Genentech retained warrants for the
exercise of additional common stock in the event of a second private placement
in excess of $10 million or an Initial Public Offering (IPO). Such warrants were
exercisable at the issue price per share of the additional capital raised and
would allow Genentech to maintain its 25% ownership interest. The warrants
expired unexercised at the completion of the Company's 1998 private placement in
January 1999. Genentech no longer has any rights to maintain its proportionate
ownership position.

     The license agreement between the Company and Genentech, in part, defines
the working relationship between the companies. Genentech has granted the
Company an exclusive license to all patents and proprietary know-how that
Genentech is free to license or sublicense related to the development of a
vaccine to prevent HIV infection. Certain of the licensed technology is
sublicensed or assigned to the Company under licenses from third parties to
Genentech. The Company, as the exclusive licensee of Genentech, has assumed
                                       39
<PAGE>   40
                                  VAXGEN, INC.
                        (A DEVELOPMENT STAGE ENTERPRISE)

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

all of Genentech's obligations under these third-party license agreements. Such
obligations consist primarily of royalties on product sales. However, the
vaccine in its current form does not incorporate any technology sublicensed or
assigned to the Company for which there is an obligation under licenses from
third parties. The initial term of the license agreement is 15 years from the
commercial introduction date of a licensed product and will be determined on a
country-by-country, product-by-product basis. In addition, upon entering the
agreement, Genentech transferred to the Company 300,000 doses of the vaccine.
Under the license agreement, the Company is required to use due diligence in
developing, seeking regulatory approval for, and marketing and commercializing
the vaccine. Due diligence is defined in the agreement as meaning that the
development and commercialization of the vaccine will be the Company's sole
business goal, with an expenditure of time, effort and funding that is
commensurate with such goal.

     In connection with reaching this goal, the Company is required to achieve
the filing of the first market approval for a product with the FDA not later
than the fifth anniversary of the closing of the private placement, which
occurred in 1997. The Company and Genentech can agree to extend this
requirement, subject to a two-year limit. If the Company fails to exercise due
diligence or maintain a tangible net worth of at least $1,000,000, Genentech has
the right to convert the exclusive license to a non-exclusive license, and may
be entitled to terminate the license.

     As part of the license agreement, Genentech has an option to manufacture
the vaccine and a one-time option to be responsible for marketing the vaccine
worldwide. Should Genentech exercise its marketing option, Genentech will pay a
license fee to the Company equal to 33% of the Company's developmental costs of
the initial AIDSVAX product (including the Phase III clinical trials and
regulatory submissions), as well as a percentage of ongoing profits on the sales
of the vaccine. If Genentech does not elect its marketing option, it will
receive a royalty on product sales; the royalty rate depends on whether
Genentech elects to manufacture the vaccine being sold commercially.

     The Company has a service contract with Genentech whereby Genentech
supplies research, vaccine production, and administrative and regulatory support
to the Company. The contract expires on December 31, 2000. Expenses incurred by
the Company for 1999, 1998 and 1997 were $1,679,000, $690,000 and $2,352,000,
respectively, under the contract. In excess of 95% of costs represent research
and development expenses in each period and the remainder is general and
administrative expenses.

     Prior to September 1998, the Company leased office space from Genentech.
Rent expense under this lease was $0, $80,000, and $18,000 in 1999, 1998, and
1997, respectively.

     Management believes that the terms of the agreement provide Genentech full
reimbursement for specifically identified actual direct costs as well as
indirect and overhead costs incurred related to the Company. Charges for
indirect and overhead costs are based upon a percentage of direct costs.
Management believes this method results in a reasonable allocation of costs to
the Company.

 5. INITIAL PUBLIC AND PRIVATE PLACEMENT STOCK OFFERINGS

     In 1997, the Company completed a private placement sale of 3,607,047 shares
of its common stock at a price of $7.00 per share resulting in proceeds of
$23,001,000, net of issuance costs of $2,248,000. A total of 149,270 shares in
this private placement were sold to related parties. In conjunction with the
1997 private placement and under agreements with the Company, Genentech
converted a $1,000,000 line of credit with the Company and invested an
additional $1,000,000 in the Company in return for 285,714 shares of the
Company's common stock. Additionally, in October 1997, Genentech exercised its
option to maintain a 25% ownership interest in the Company (note 4), which
resulted in the issuance of 86,640 shares of the Company's common stock in
October 1997.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     In 1998, the Company initiated a second private placement sale of its
common stock at a price of $9.50 per share. The first closing and issuance of
common shares in the private placement was completed in December 1998 and
resulted in the sale of 986,097 shares of the Company's common stock and
proceeds of $8,604,000, net of issuance costs of $764,000. A total of 33,629
shares in the first closing were sold to related parties. The final closing and
issuance of 583,913 shares of common stock for proceeds of $5,273,000, net of
issuance costs of $274,000, occurred in January 1999. A total of 2,000 shares
were sold to related parties in the final closing.

     The Company completed its initial public offering (the "IPO") in July 1999,
in which it issued and sold 3,565,000 shares of common stock for aggregate
proceeds to the Company of $46,345,000. Of the aggregate proceeds received in
the IPO, $4,386,000 was used to pay costs and expenses related to the IPO,
resulting in net proceeds of approximately $42,000,000.

     In 1999, the Company completed a private placement of common stock with
Vulcan Ventures, Inc. for a private placement of common stock. The issuance of
the common shares in the private placement was completed in December 1999 and
resulted in the sale of 2,173,913 shares of the Company's common stock and
proceeds of approximately $24,000,000, net of issuance costs.

 6. STOCK OPTIONS AND WARRANTS

(a) STOCK OPTION PLANS

  1996 Stock Option Plan

     The Company's 1996 Stock Option Plan (the Plan) has 1,750,000 shares of
common stock reserved for grant. Options granted under the Plan may be
designated as qualified or nonqualified at the discretion of the compensation
committee of the Board of Directors. At December 31, 1999, 457,690 shares were
available for grant under the Plan.

     Generally, shares under option vest ratably over four years, beginning one
year from the date of grant; however, options can vest upon grant. All options
expire no later than ten years from the date of grant. Qualified stock options
are exercisable at not less than the fair market value of the stock at the date
of grant and nonqualified stock options are exercisable at prices determined at
the discretion of the Board of Directors, but not less that 85% of the fair
market value of the stock at the date of grant.

  1998 Director Stock Option Plan

     In 1998, the Board of Directors approved the 1998 Director Stock Option
Plan (the Director Plan) for nonemployee directors. Under the Director Plan,
37,500 shares of common stock are reserved for grant. In May 1998, nonemployee
directors were granted options to purchase 8,571 shares of the Company's common
stock at an exercise price of $7.00 per share. Such options vested immediately.
Under the Director Plan, options are automatically granted to nonemployee
directors on the date of the annual shareholders' meeting. The exercise price of
each annual option grant is to be the fair market value of the Company's common
stock on the grant date. Each annual option grant fully vests on the first
anniversary of its grant date, subject to certain meeting attendance
requirements. At December 31, 1999, 34,643 shares were available for grant under
the Director Plan.

</TABLE>

     The weighted average remaining contractual life of stock options
outstanding at December 31, 1999 is 8.8 years.

     The fair value of each option grant is estimated on the date of grant using
the minimum value method with the following assumptions used for grants in 1999,
1998 and 1997: expected dividend yield of 0%; expected volatility of 0% for the
periods up to the initial public offering (June 30, 1999) and 116% for the
period in 1999 subsequent to the initial public offering; risk-free interest
rate of 6.75%, 6.0% and 6.0%; and expected lives of four years.

     Had compensation cost pursuant to the plans been determined consistent with
SFAS 123, the Company's net loss and loss per share would have been adjusted to
the pro forma amounts indicated below:

     During 1998, the Board of Directors approved for grant options to purchase
174,925 shares of the Company's common stock at an exercise price of $7.00 per
share and 302,900 shares at an exercise price of $9.50 per share. However, since
the grant of such options would have caused the number of shares outstanding to
exceed the number of shares reserved for grant under the Plan, the Company's
shareholders had to approve an increase in the number of shares reserved for
grant under the Plan. In April 1999, the shareholders of the Company approved an
increase in the number of shares reserved for grant under the Plan to 1,750,000
shares. This represents the measurement date for previously granted but
unapproved options. As a result, the Company recorded deferred compensation in
the amount of $3,223,000, representing the excess of fair market value of the
common shares in April 1999, $13.00 per share, over the exercise price of the
options on the date stockholder approval was obtained. The Company has recorded
charges to compensation expense of $972,000 for the portion of the vesting
period lapsed at December 31, 1999. The balance of deferred compensation is
being amortized to expense over the remaining vesting period of the options.

(b) COMMON STOCK WARRANTS

     In connection with the Company's 1997 private placement, certain
consultants were issued warrants to purchase approximately 219,000 shares of the
Company's common stock exercisable at $7.00 per share through June 2007. No
warrants have been exercised to date.

     The Company similarly issued warrants to purchase approximately 91,000
shares of the Company's common stock exercisable at $9.50 per share to certain
consultants in connection with the Company's 1998 private placement. Such
warrants were earned in December 1998 and January 1999. The warrants are to be
exercisable through 2009. No warrants have been exercised to date.

     Additionally, in connection with the 1997 private placement, the Company
granted an unrelated party a first option to maintain its approximately 4.8%
interest in the Company. Such right allows the party the option to acquire a
proportionate number of shares at an equivalent price to maintain its ownership
percentage through March 31, 2002. The party exercised its option in connection
with the 1998 private placement.

     In 1999, in connection with the resolution of an employment matter, the
Company issued warrants to purchase 150,000 shares of the Company's common stock
exercisable at $7.00 per share. As a result of the warrant issuance, the Company
recorded compensation expense of approximately $2,000,000.

     In 1999, the Company issued warrants to purchase approximately 35,000
shares of the Company's common stock exercisable at $11.50 per share to certain
consultants in connection with the Company's 1999 private placement with Vulcan
Ventures, Inc. Such warrants were earned in December 1999. The warrants are
exercisable through 2009. No warrants have been exercised to date.

 7. INCOME TAXES

     The Company has reported no income tax benefits due to limitations on the
recognition of deferred tax assets for financial reporting purposes.

     The tax effects of temporary differences and carryforwards that give rise
to deferred tax assets are as follows:

</TABLE>

     Based on the weight of available evidence, including cumulative losses
since inception and expected future losses, the Company has determined that it
is more likely than not the entire deferred tax asset amount will not be
realized and, therefore, a valuation allowance has been provided on all gross
deferred tax assets.

     The increases in the valuation allowance for deferred tax assets of
$10,186,000, $3,299,000 and $1,203,000 in 1999, 1998 and 1997, respectively, are
primarily attributable to increases in net operating loss and tax credit
carryforwards.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     At December 31, 1999 the Company had net operating loss carryforwards of
approximately $35,122,000 and research and experimentation credit carryforwards
of approximately $941,000 which are available to offset future Federal taxable
income and income taxes, respectively, if any, and expire beginning in 2010.

 8. COMMITMENTS

(a) LEASES

     The Company leases office facilities under noncancelable operating leases,
which expire from 2002 to 2006. Until September 1998, the Company also leased
office space from Genentech.

     In August 1998, the Company commenced a lease for office space at Mahidol
University in Bangkok, Thailand, ending at the conclusion of Phase III clinical
trials in Thailand. The lease requires monthly payments of $2,000. Additionally,
the Company began renovation of project office space at Taksin Hospital, also in
Bangkok. The Company is required to pay up to $100,000 for renovations, for
which the Company will receive use of the facility for a five-year term at no
additional cost.

     The Company entered into an 88 month laboratory lease commencing in January
1999, which requires the Company to expend a minimum of $500,000 in leasehold
improvements, in addition to its scheduled lease payments.

     Minimum annual payments under the foregoing leases at December 31, 1999,
are as follows:

<TABLE>
<S>                                         <C>
2000......................................  $629,000
2001......................................   655,000
2002......................................   670,000
2003......................................   682,000
2004......................................   708,000
Thereafter................................   627,000
</TABLE>

     Rent expense for 1999, 1998 and 1997 was $901,000 and $353,000 and $66,000,
respectively.

(b) EMPLOYMENT AGREEMENTS

     The Company has employment contracts with certain members of management
ending from 2000 to 2003. Such agreements provide for discretionary bonuses and
annual increases in compensation as determined by the Board of Directors.
Minimum compensation under these contracts aggregates $1,185,000 annually. The
employment contracts with three members of management also provide for the
issuance of an aggregate of 325,757 shares of the Company's common stock to
these individuals if the Company is acquired in an acquisition that results in a
purchase price of at least $28.00 per share or once the per share value of the
Company's common stock has attained an average price of $28.00 over a 30 day
period. If the shares are issued as a result of the common stock reaching an
average value of $28.00 per share, the Company will record an immediate charge
to expense equal to the per share value of the common stock to be issued. For
example, if the per share value of the stock upon issuance is $28.00, the charge
to expense will be $9,100,000.

(c) CLINICAL TRIALS

     In connection with Phase III clinical trials, the Company has contracted
for the services of 61 medical clinics in North America and 17 medical clinincs
in Thailand associated with the Bangkok Metropolitan Administration. The clinics
will provide the location, clinicians, oversight, and volunteers for the three
year testing of the Company's vaccine. Payment will be made over the period
based on the number of volunteers vaccinated, the number of return visits and
the subsequent testing and follow-up of these volunteers. Total

Closing Date, a right of first refusal to purchase its pro rata share of New
Securities (as defined in this Section 4) which the Company may, from time to
time, propose to sell and issue. Purchaser's pro rata share, for purposes of
this right of first refusal, is the ratio of the number of outstanding shares of
Common Stock and Common Stock issuable upon conversion of any convertible
security held of record by Purchaser immediately prior to the issuance of New
Securities to the total number of shares of Common Stock outstanding and Common
Stock issuable upon conversion of any convertible security outstanding
immediately prior to the issuance of New Securities. This right of first refusal
shall be subject to the following provisions:

     4.1  "New Securities" shall mean any Common Stock of the Company whether
now authorized or not, issued in exchange for cash in a private placement
transaction. New Securities shall not include (i) securities issuable upon
exercise of existing rights to acquire Common Stock issued to consultants or
vendors of the Company, or (ii) any other issuances of capital stock of the
Company, or rights to acquire capital stock of the Company, which do not exceed
an aggregate of 268,481 shares of Common Stock, or the issuance of rights to
acquire such number of shares of Common Stock, or securities convertible into
such number of shares of Common Stock.

     4.2  In the event the Company proposes to undertake an issuance of New
Securities, it shall give Purchaser written notice of its intention, describing
the type of New Securities, and their price and the general terms upon which the
Company proposes to issue the same. Purchaser shall have 20 days after any such
notice is effective to agree to purchase Purchaser's pro rata share of such New
Securities for the price and upon the terms specified in the notice by giving
written notice to the Company and stating therein the quantity of New Securities
to be purchased.

     4.3  In the event Purchaser fails to exercise fully the right of first
refusal within said 20-day period, the Company shall have 120 days thereafter to
sell or enter into an agreement (pursuant to which the sale of New Securities
covered thereby shall be closed, if at all, within 120 days from the date of
said agreement) to sell the New Securities respecting which Purchaser's right of
first refusal option set forth in this Section 4 was not exercised, at a price
and upon terms no more favorable to the purchasers thereof than specified in the
Company's notice to Purchaser pursuant to Section 4. In the event the Company
has not entered into an agreement to sell the New Securities within said 120-day
period (or sold and issued New Securities in accordance with the foregoing
within 120 days from the date of said agreement), the Company shall not
thereafter issue or sell any New Securities, without first again offering such
securities to Purchaser in the manner provided in Section 4 above.
