GENERAL

InterMune develops and commercializes innovative products for the treatment
of serious pulmonary and infectious diseases and cancer. We have two marketed
products, growing product revenues, and advanced-stage clinical programs which
target a maximum market opportunity of approximately $4.5 billion. In the United
States, we market our lead product, ACTIMMUNE-REGISTERED TRADEMARK-, for the
treatment of chronic granulomatous disease, a life-threatening congenital
disorder of the immune system, and severe, malignant osteopetrosis, a life
threatening congenital disorder causing an overgrowth of bony structures.
Worldwide, we market Amphotec-Registered Trademark- for the treatment of
invasive aspergillosis, a life-threatening systemic fungal infection.

We have mid- or advanced-stage trials underway for ACTIMMUNE and Amphotec in
a range of new disease indications, including:

- idiopathic pulmonary fibrosis, a life-threatening lung condition;

- infections caused by a type of bacteria known as mycobacteria
(mycobacterial infections), such as tuberculosis and atypical
mycobacterial infections;

- infections caused by various fungi that attack patients with weakened
immune systems (systemic fungal infections), such as cryptococcal
meningitis and invasive aspergillosis;

1

- ovarian cancer, as well as other types of cancer, a life-threatening
disease caused by uncontrolled growth of cells; and

- cystic fibrosis, a congenital disorder that leads to chronic pulmonary
infections in children.

We believe the most significant near-term use of ACTIMMUNE is for the
treatment of idiopathic pulmonary fibrosis, which afflicts approximately 50,000
persons in the United States. We are conducting a clinical trial by which we
intend to provide sufficient data for approval, known as a Phase III pivotal
clinical trial, to test the efficacy of ACTIMMUNE for the treatment of this
condition. We have also commenced enrollment in a Phase III pivotal clinical
trial of ACTIMMUNE for the treatment of multidrug-resistant tuberculosis.

We are currently conducting a clinical trial to determine dosing and
efficacy, known as a Phase II clinical trial, of ACTIMMUNE in combination with
amphotericin B for the treatment of cryptococcal meningitis, a life-threatening
systemic fungal infection. We are currently in the planning stages for a
clinical trial of ACTIMMUNE in combination with Amphotec for the treatment of
invasive aspergillosis, a life-threatening systemic fungal infection. The active
ingredient in Amphotec is amphotericin B. We are also conducting Phase II
clinical trials of ACTIMMUNE for the treatment of atypical mycobacterial
infections and cystic fibrosis. We are also currently in the planning stages for
a Phase III pivotal clinical trial of ACTIMMUNE for the treatment of ovarian
cancer.

Interferon gamma-1b, the active ingredient in ACTIMMUNE, is a human protein
which plays a key role in preventing the formation of excessive scar, or
fibrotic, tissue and is a potent stimulator of the immune system. The results of
a clinical trial published in October 1999 in THE NEW ENGLAND JOURNAL OF
MEDICINE showed statistically significant evidence that interferon gamma-1b can
halt and reverse the progression of idiopathic pulmonary fibrosis. In addition,
both animal studies, known as preclinical studies, and clinical trials have
demonstrated the therapeutic potential of interferon gamma-1b against a broad
range of infectious diseases, notably mycobacterial and systemic fungal
infections. A study published in May 1997 in THE LANCET showed that ACTIMMUNE
was effective in the treatment of multidrug-resistant tuberculosis, a type of
mycobacterial infection.

Idiopathic pulmonary fibrosis ($2.5 billion), mycobacterial infections
($500 million), systemic fungal diseases ($500 million), cystic fibrosis
($500 million) and ovarian cancer ($500 million) are serious and difficult to
treat diseases that we believe represent a combined maximum market opportunity
for ACTIMMUNE of approximately $4.5 billion annually in the United States.

In January 2001, we acquired our second FDA-approved product, Amphotec, from
ALZA Corporation. Amphotec is a lipid-complexed form of amphotericin B and is
approved for invasive aspergillosis, a life-threatening systemic fungal
infection. Amphotec is marketed in over 20 countries. InterMune has global
rights to Amphotec and plans to relaunch the product in 2001.

In addition to our late stage product development efforts with ACTIMMUNE and
Amphotec, we have in preclinical development a monoclonal antibody for
infections caused by pseudomonas aeruginosa and a small molecule for infections
caused by staphylococcus aureus.

ACTIMMUNE

The active ingredient in ACTIMMUNE is interferon gamma-1b. Interferons are
comprised of two families of related proteins that are secreted by a variety of
cells in the body. Interferon alpha and interferon beta, which are included in
one family, have been approved and are currently marketed for the treatment of
diseases such as hepatitis B infection and multiple sclerosis. However,
interferon alpha and interferon beta are associated with serious adverse side
effects that may result in discontinuation of therapy. Interferon gamma, which
is included in a separate family of interferons, is biologically distinct from
interferon alpha and interferon beta. Interferon gamma has a superior safety
profile as compared to interferon alpha and interferon beta because it results
in fewer and less severe adverse side effects.

2

ACTIMMUNE performs two important activities in the human body. First,
ACTIMMUNE regulates the activity of the body's scar-forming cells, called
fibroblasts. ACTIMMUNE directly blocks the multiplication of fibroblasts and
also inhibits the production and action of TGF-beta, a potent scar-inducing
molecule. The result of these actions is the prevention of excessive scarring,
which is known as anti-fibrotic activity. The anti-fibrotic activity of
ACTIMMUNE has been demonstrated in both preclinical studies and in clinical
trials. We are pursuing a Phase III pivotal clinical trial using ACTIMMUNE for
the treatment of idiopathic pulmonary fibrosis because prior clinical trials
have demonstrated its anti-fibrotic activity.

ACTIMMUNE's second important activity in the body is to activate the immune
system by stimulating a class of immune cells known as macrophages. This action
results in increased killing and removal of infectious organisms, such as
bacteria and fungi. We believe that interferon gamma-1b may have the broadest
range of therapeutic activity in bacterial and fungal diseases of any protein
yet identified. This activity enhances the body's ability to fight infection and
is the reason we are developing ACTIMMUNE for use in the treatment of infectious
diseases.

AMPHOTEC

Amphotec is an FDA-approved lipid-complexed form of amphotericin B indicated
for the treatment of invasive aspergillosis, a life-threatening systemic fungal
infection. Amphotec is sold outside of the United States under the trade name
Amphocil-Registered Trademark- in more than 20 countries. The product was
originally developed by SEQUUS Pharmaceuticals, Inc., which was acquired by Alza
Corporation in 1999. In January 2001, InterMune acquired worldwide rights to
Amphotec from Alza. The product has not been aggressively marketed to physicians
for at least two years. InterMune is preparing to relaunch Amphotec in 2001 and
is in the planning stages of a clinical trial for Amphotec in combination with
ACTIMMUNE for invasive aspergillosis.

STRATEGY

We plan to pursue a growth strategy through the following:

GROW PRODUCT REVENUE. For the year 2000, we increased the sales of ACTIMMUNE
by approximately 142% in the United States, compared to 1999. We accomplished
this increase in sales by heightening awareness of ACTIMMUNE through direct
mailings, trade shows, our 12 medical science liaisons in the field and other
activities. Although ACTIMMUNE is currently approved for only chronic
granulomatous disease and severe, malignant osteopetrosis, we believe that some
physicians are prescribing ACTIMMUNE to treat patients with idiopathic pulmonary
fibrosis, as well as other diseases, based on available clinical data and
publications reviewing such data in THE NEW ENGLAND JOURNAL OF MEDICINE, THE
LANCET, THORAX and other peer-reviewed publications.

DEVELOP A SALES AND MARKETING ORGANIZATION TO SERVE PULMONOLOGISTS AND
INFECTIOUS DISEASE SPECIALISTS. Pulmonologists are the physicians who generally
treat idiopathic pulmonary fibrosis, and infectious disease specialists are the
physicians who generally treat systemic fungal infections, multidrug-resistant
tuberculosis and atypical mycobacterial infections. Accordingly, we are
developing a sales and marketing organization to support the approximately 7,000
pulmonologists and 4,000 infectious disease specialists practicing in the United
States. Because these pulmonologists and infectious disease specialists are
primarily hospital-based and concentrated in major metropolitan areas, we
believe that a focused marketing organization and specialized sales force can
effectively serve them. We have 38 field specialists who market and sell
ACTIMMUNE and Amphotec for FDA-approved diseases, and educate physicians and
increase their awareness of ACTIMMUNE and Amphotec. We intend to increase the
number of field specialists to 60 by mid-2001.

3

EXPAND THE NUMBER OF FDA-APPROVED DISEASE INDICATIONS FOR ACTIMMUNE. We plan
to develop ACTIMMUNE for a number of diseases where preclinical studies and
clinical trials have shown promise for interferon gamma-lb as a potential
treatment. Some of the diseases for which ACTIMMUNE has demonstrated therapeutic
activity include idiopathic pulmonary fibrosis, mycobacterial infections,
systemic fungal infections, ovarian cancer and cystic fibrosis. We believe that
the risks and time required to obtain FDA approval of ACTIMMUNE for new diseases
may be reduced because of its established safety profile. We also believe that
the life-threatening nature of some of the diseases that we intend to treat may
enable us to obtain accelerated, or fast track, approval for ACTIMMUNE for some
of these diseases. In addition, we plan to develop Amphotec in combination with
ACTIMMUNE for systemic fungal disease.

CONTINUE TO IN-LICENSE PRECLINICAL AND DEVELOPMENT-STAGE PROGRAMS, AND
FDA-APPROVED PRODUCTS. We plan to continue to in-license and acquire rights to
preclinical and development-stage programs, and FDA-approved products,
especially those for the treatment of life-threatening pulmonary and infectious
diseases. To date, we have in-licensed ACTIMMUNE, Amphotec, our staphylococcus
aureus monoclonal antibody program and our pseudomonas aeruginosa small molecule
program. We believe that our development expertise and focus, as well as our
financial resources, will provide us with significant opportunities to
in-license or acquire additional products and programs from pharmaceutical and
biotechnology companies, as well as research and academic institutions.

MARKETED PRODUCTS

ACTIMMUNE

ACTIMMUNE is currently approved for the treatment of chronic granulomatous
disease and severe, malignant osteopetrosis. Chronic granulomatous disease is a
life-threatening congenital disorder that causes patients, mainly children, to
be vulnerable to severe recurrent bacterial and fungal infections. This results
in frequent and prolonged hospitalizations and is commonly a cause of death. In
1990, ACTIMMUNE was approved by the FDA for the treatment of chronic
granulomatous disease based on its ability to reduce the frequency and severity
of serious infections associated with this disease. Overall, patients treated
with ACTIMMUNE had 67% fewer disease-related infections and hospitalizations
compared to the placebo group.

There are approximately 400 patients with chronic granulomatous disease in
the United States for whom treatment with ACTIMMUNE may be appropriate, and
there is no FDA-approved treatment specifically for this disease other than
ACTIMMUNE. Based on the indicated dosage levels of 100 micrograms of ACTIMMUNE
three times per week, the annual cost per patient is approximately $25,000.
Accordingly, we believe that chronic granulomatous disease represents a maximum
annual market opportunity of approximately $10 million in the United States for
ACTIMMUNE.

Severe, malignant osteopetrosis is a life-threatening, congenital disorder
that results in increased susceptibility to infection and an overgrowth of bony
structures that may lead to blindness and/or deafness. In February 2000, the FDA
approved ACTIMMUNE for the treatment of severe, malignant osteopetrosis and
granted ACTIMMUNE orphan drug status for this indication. The disorder primarily
affects children, and no other effective treatment is currently available other
than ACTIMMUNE.

There are approximately 400 patients with severe malignant osteopetrosis in
the United States for whom treatment with ACTIMMUNE may be appropriate. Based on
the indicated dosage levels for osteopetrosis patients of 100 micrograms of
ACTIMMUNE three times per week, the annual cost per patient is approximately
$25,000. Accordingly, we believe that severe, malignant osteopetrosis represents
a maximum annual market opportunity of approximately $10 million in the United
States for ACTIMMUNE.

AMPHOTEC

Amphotec is currently approved for invasive aspergillosis, a
life-threatening systemic fungal infection. Systemic fungal infections that do
not respond to initial treatment with standard antifungal treatment regimens are
typically treated with amphotericin B, the active ingredient in Amphotec. There
are approximately 100,000 cases of systemic fungal infection each year in the
United States, of which approximately 30,000 to 40,000 do not respond to
initial therapy.

ACTIMMUNE--DISEASE TREATMENTS UNDER DEVELOPMENT

IDIOPATHIC PULMONARY FIBROSIS

Idiopathic pulmonary fibrosis is a life-threatening disease characterized by
progressive scarring, or fibrosis, of the lungs, which leads to their
deterioration and destruction. The cause of idiopathic pulmonary fibrosis is
unknown. The prognosis is poor for patients with idiopathic pulmonary fibrosis,
which occurs primarily in persons 40 to 70 years old. Most patients die from
progressive loss of lung function, which leads to suffocation. The median life
span for patients suffering from idiopathic pulmonary fibrosis is approximately
three to five years from the time of diagnosis. There are approximately 50,000
patients in the United States with idiopathic pulmonary fibrosis. In
October 2000, we commenced enrollment in a Phase III pivotal clinical trial for
this disease.

CURRENT THERAPY. Treatment options for idiopathic pulmonary fibrosis are
limited and only minimally effective. Approximately 70% to 80% of patients with
idiopathic pulmonary fibrosis do not respond to any currently available drug
therapy. Attempted drug therapies include high dose corticosteroids and
anti-cancer drugs, both of which are minimally effective and may result in
significant adverse side effects. For these reasons, treatment with
corticosteroids and anti-cancer drugs is not recommended for all patients with
idiopathic pulmonary fibrosis. As a last resort, a small percentage of patients
undergo lung transplantation, but donors are limited, and many patients die
while awaiting a transplant.

5

PRIOR CLINICAL TRIALS OF INTERFERON GAMMA-1B AS A TREATMENT FOR IDIOPATHIC
PULMONARY FIBROSIS. Independent investigators conducted two clinical trials of
interferon gamma-1b for the treatment of idiopathic pulmonary fibrosis. The
results of these clinical trials demonstrated that interferon gamma-1b can be
safely administered with minimal adverse side effects and can halt and reverse
the deterioration in lung function in patients.

The results of one of these clinical trials, a Phase II clinical trial
published in October 1999 in THE NEW ENGLAND JOURNAL OF MEDICINE, demonstrated
that interferon gamma-1b may be effective in the treatment of idiopathic
pulmonary fibrosis. Investigators at the University of Vienna conducted the
clinical trial with 18 patients who had not responded to treatment with
corticosteroids or anti-cancer agents. Nine patients were treated for 12 months
with oral prednisolone, a corticosteroid, and nine patients were treated with a
combination of interferon gamma-1b and prednisolone.

Lung function, as measured by total lung capacity and blood oxygen levels,
deteriorated in all nine patients in the group given prednisolone alone. Total
lung capacity decreased from a mean of 66% at the start of the trial to 62%
after 12 months. In contrast, in the group receiving interferon gamma-1b plus
prednisolone, total lung capacity increased from a mean of 70% at the start of
the trial to 79% after 12 months. Similarly, in the nine patients in the group
given prednisolone alone, blood oxygen levels of patients at rest decreased from
a mean of 65% at the start of the trial to 62% after 12 months. In the group
receiving interferon gamma-1b plus prednisolone, blood oxygen levels of patients
at rest increased from a mean of 65% at the start of the trial to 76% after
12 months. Both of these results are statistically significant, each with a p
value < 0.001. This means that, applying widely-used statistical methods, the
chance that these results occurred by accident is less than 1 in 1000. All
patients treated with interferon gamma-1b exhibited improved pulmonary function
for the trial period of 12 months. In contrast, patients receiving treatment
with prednisolone alone showed gradual impairment of their pulmonary function,
and two of them died following the 12-month clinical trial.

These results confirmed the observations of an initial clinical trial in
patients, or Phase I/II clinical trial, by the same investigators. In this
initial clinical trial, the investigators tested safety and dosing of interferon
gamma-1b in combination with prednisolone for the treatment of idiopathic
pulmonary fibrosis in 30 patients. The clinical data showed that the ten
patients who received 200 micrograms of ACTIMMUNE demonstrated overall
improvement in lung function. In the ten patients that received 100 micrograms
of interferon gamma-1b, four showed improvement. None of the ten patients in the
control group, who were not treated with interferon gamma-1b, improved. Overall,
the investigators concluded that patients who received interferon gamma-1b in
combination with prednisolone showed significant improvement in lung function
compared to the control group that received prednisolone alone.

OUR PHASE III PIVOTAL CLINICAL TRIAL. We are continuing the clinical
development of ACTIMMUNE in idiopathic pulmonary fibrosis through our Phase III
pivotal clinical trial. Our clinical trial is enrolling patients with documented
idiopathic pulmonary fibrosis who have not responded to previous treatment with
corticosteroids and who have evidence of deteriorating lung function. Our
260-patient trial will compare 200 micrograms of ACTIMMUNE in combination with
corticosteroids to a control group that receives corticosteroids alone. Outcomes
will include several measures of lung function, including lung capacity, blood
oxygen levels, and several measures of quality of life.

IDIOPATHIC PULMONARY FIBROSIS MARKET. We believe that there are
approximately 50,000 patients with idiopathic pulmonary fibrosis in the United
States. Based on the expected dosing level of 200 micrograms of ACTIMMUNE three
times per week for idiopathic pulmonary fibrosis patients, the annual cost per
patient would be approximately $50,000. Assuming this treatment regimen, we
believe that idiopathic pulmonary fibrosis represents a maximum annual market
opportunity of approximately $2.5 billion in the United States for ACTIMMUNE. In
addition, if ACTIMMUNE is approved to treat idiopathic pulmonary fibrosis, we
anticipate that it may also be used to treat some other forms of

6

pulmonary fibrosis, including fibrosis caused by sarcoidosis, radiation, some
environmental exposures, and connective tissue diseases such as scleroderma.

MYCOBACTERIAL INFECTIONS

Mycobacteria are the cause of several infectious diseases, including
tuberculosis, multidrug-resistant tuberculosis, and atypical mycobacterial
infections. Tuberculosis is a major worldwide health threat. Tuberculosis is a
difficult disease to treat and requires multidrug regimens of at least six
months for eradication. It is estimated that 1% to 10% of tuberculosis cases,
classified as multidrug-resistant tuberculosis, are caused by mycobacteria that
are resistant to standard drug therapy. During the past ten years,
multidrug-resistant tuberculosis has emerged as a global health issue.

In the United States, each year there are approximately 17,000 new cases of
tuberculosis, of which approximately 170 are multidrug-resistant tuberculosis,
and 4,000 cases of atypical mycobacterial infection. In Japan, where we have
commercial rights for the use of ACTIMMUNE in the treatment of infectious
diseases, including tuberculosis, there are approximately 43,000 new cases of
tuberculosis each year, of which approximately 2,000 are multidrug-resistant
tuberculosis. Based upon expected dosing levels of 100 to 500 micrograms of
ACTIMMUNE three times per week, we believe that mycobacterial infections
represent a maximum annual market opportunity of approximately $500 million for
ACTIMMUNE in the United States and Japan.

MULTIDRUG-RESISTANT TUBERCULOSIS

A clinical trial conducted at Bellevue Hospital in New York and published in
THE LANCET in May 1997 found that patients with multidrug-resistant tuberculosis
were able to respond to conventional tuberculosis drugs when ACTIMMUNE was added
to their treatment regimen. In contrast, none of these patients had responded to
conventional tuberculosis drugs alone after an average of 13 months of therapy.
In July 2000, we commenced enrollment in a Phase III pivotal clinical trial of
ACTIMMUNE for the treatment of multidrug-resistant tuberculosis.

ATYPICAL MYCOBACTERIAL INFECTION

In May 1994, THE NEW ENGLAND JOURNAL OF MEDICINE published the results of a
clinical trial showing ACTIMMUNE to be successful in reducing fever and other
signs of infection in patients with atypical mycobacterial infection. In
January 2000, we commenced enrollment in a Phase II clinical trial of ACTIMMUNE
for the treatment of atypical mycobacterial infections.

OVARIAN CANCER

Ovarian cancer is the third most common cancer in women, and accounts for
over 14,000 deaths in the United States per year. Current treatment with
chemotherapy is suboptimal, with a five-year survival of only 44%. Interferon
gamma has been shown to be directly toxic to ovarian cancer cells, and
interferon gamma-lb stimulates the body's immune system to enhance the removal
of cancer cells. A recent study from Europe in 148 women showed that the
addition of interferon gamma to conventional chemotherapy increased the time to
disease progression from an average of 17 months to 48 months. Complete
responses were seen in 68% of women receiving interferon gamma with conventional
therapy compared to 56% of women receiving conventional therapy alone. We plan
to initiate a Phase III pivotal clinical trial of ACTIMMUNE in combination
therapy for the treatment of ovarian cancer.

7

In 1998, ovarian cancer affected 189,000 women in the United States. We
believe that 25,000 new cases are diagnosed annually in the United States. We
believe that ovarian cancer represents a maximum annual market opportunity of
approximately $500 million for ACTIMMUNE in the United States.

SYSTEMIC FUNGAL INFECTIONS--CRYPTOCOCCAL MENINGITIS

Systemic fungal infections, such as cryptococcal meningitis and invasive
aspergillosis, are life-threatening diseases caused by various fungi that attack
patients with weakened immune systems. Currently available therapies for these
infections are often ineffective and result in serious adverse side effects.
Mortality from systemic fungal infections remains high. There is a clear need
for new, effective, and less toxic therapies to treat them. Recent research
results support the potential benefit of combining ACTIMMUNE with conventional
antifungal therapy, such as amphotericin B, in the treatment of several of the
most prevalent types of systemic fungal infections. Because ACTIMMUNE works by
acting directly on the immune system, we believe that new antifungal agents may
also have greater efficacy when combined with ACTIMMUNE.

Our strategy for the development of ACTIMMUNE for the treatment of systemic
fungal diseases is twofold. We plan to conduct clinical trials for ACTIMMUNE in
combination with amphotericin B. To this end, we are currently conducting a
Phase II clinical trial designed to determine dose and efficacy of ACTIMMUNE in
combination therapy with amphotericin B for the treatment of cryptococcal
meningitis. In addition, due to our recent purchase of Amphotec, a
lipid-complexed form of amphotericin B, we plan to initiate trials of ACTIMMUNE
in combination with Amphotec.

There are approximately 100,000 patients with systemic fungal infections in
the United States. Based on expected dosing levels of 100 micrograms of
ACTIMMUNE three times per week for these patients, we believe that systemic
fungal infections represent a maximum annual market opportunity of approximately
$500 million for ACTIMMUNE in the United States.

CYSTIC FIBROSIS

Cystic fibrosis is a congenital disorder that leads to chronic pulmonary
infections in children, usually by four years of age. These infections result in
an exaggerated inflammatory response, leading to clogging and obstruction of the
airways. Chronic pulmonary infection is the major cause of mortality in these
patients. Due to its ability to regulate the immune system, we believe that
ACTIMMUNE may have the potential to modify many of the processes that lead to
the exaggerated inflammation and to reduce the chronic inflammation in the
lungs. By preventing excessive inflammation in the airways, ACTIMMUNE may be
able to slow the progression of pulmonary deterioration.

In February 2000, we commenced enrollment in a Phase II clinical trial of
ACTIMMUNE in patients with cystic fibrosis. Cystic fibrosis affects an estimated
23,000 persons in the United States. We believe that cystic fibrosis represents
a maximum annual market opportunity of approximately $500 million for ACTIMMUNE
in the United States.

OTHER PROGRAMS

PA MONOCLONAL ANTIBODY--PSEUDOMONAS AERUGINOSA INFECTION

Pseudomonas aeruginosa is a bacterial infection that often affects patients
using respirators and catheters as well as patients with a number of conditions,
including burns, low white blood cell counts, and cystic fibrosis. Because the
types of patients at risk generally have pre-existing illnesses, pseudomonas
aeruginosa infection most often occurs in a hospital setting.

Scientists at the Medical College of Wisconsin have identified a protein,
designated PcrV, on the surface of pseudomonas aeruginosa bacteria that enables
the bacteria to invade human tissue. By

8

directing antibodies against the PcrV protein, they have been able to
demonstrate highly effective treatment, as well as prevention, of infections
caused by pseudomonas in animal models. We are currently working with Protein
Design Labs, Inc. to generate a humanized monoclonal antibody directed against
the PcrV protein as a therapeutic, in combination with antibiotics. This
antibody would treat pseudomonas aeruginosa infection and prevent infection in
high-risk patients.

Pseudomonas aeruginosa infections account for 71,000 annual cases in the
United States of pneumonia in hospitalized patients, 30% to 40% of which die
from their pneumonia. Furthermore, chronic pseudomonas aeruginosa is the leading
cause of pulmonary infection and resulting mortality in patients with cystic
fibrosis, which affects an estimated 23,000 persons in the United States.

PA VIRULENCE INHIBITORY FACTOR--STAPHYLOCOCCUS AUREUS INFECTION

Staphylococcus aureus is a bacteria that causes diseases ranging from minor
skin infections to life-threatening deep tissue infections such as pneumonia,
meningitis, heart valve infections, post-operative wound infections, bloodstream
infections, and toxic shock syndrome. The emergence of antibiotic resistance has
made many anti-infective agents ineffective. We are working with collaborators
to discover protein fragments, known as peptides, that block infections caused
by staphylococcus aureus. The efficacy of one of these peptides, known as
virulence inhibitory factor, has been demonstrated in animal models, and we
intend to develop one or more peptides as therapy to be used in conjunction with
antibiotics in the treatment of infections caused by staphylococcus aureus. We
are also in the early stages of development for a vaccine for the prevention of
infections caused by staphylococcus aureus in high-risk populations.

In the United States, there are at least 500,000 infections caused by
staphylococcus aureus a year. These infections extend hospitalization and
increase required medical and nursing care, and it would be highly
cost-effective to immunize these high-risk patient groups with a staphylococcal
vaccine.

LICENSE AND OTHER AGREEMENTS

GENENTECH, INC. LICENSE AGREEMENT (ACTIMMUNE)

In August 1998, we entered into an agreement with Connetics Corporation
under which we obtained an exclusive sublicense under the rights granted to
Connetics by Genentech through a license agreement relating to interferon
gamma-1b. We also agreed to assume many of Connetics' obligations to Genentech
under that license agreement. We entered into an agreement with Connetics in
April 1999 in order to broaden the scope of rights granted to us. In June 2000,
we entered into an assignment and option agreement with Connetics, by which
Connetics assigned the Genentech license to us. The agreement with Genentech
terminates on the later of May 5, 2018 and the date that the last of the patents
licensed under the agreement expires.

Our licensed rights include exclusive and non-exclusive rights. The
exclusive rights are to commercialize ACTIMMUNE in the United States for the
treatment and prevention of all human diseases and conditions, including
infectious diseases, pulmonary fibrosis and cancer, but excluding arthritis and
cardiac and cardiovascular diseases and conditions. The non-exclusive rights
include the right to commercialize ACTIMMUNE for gene therapy in the United
States, except for cardiac and cardiovascular diseases and conditions. In Japan,
we have the exclusive license rights to commercialize interferon gamma-1b for
all infectious diseases. We also have the opportunity, under specified
conditions, to obtain further rights to interferon gamma-1b in Japan. Under the
Genentech license, we pay Genentech royalties on the sales of ACTIMMUNE, and
make one-time payments to Genentech upon the occurrence of specified milestone
events. We must satisfy specified obligations under the agreement with Genentech
to maintain our license from Genentech. We are obligated under the agreement to
develop and commercialize ACTIMMUNE for a number of diseases.

CONNETICS CORPORATION

Through the Assignment and Option Agreement with Connetics, beginning on
January 1, 2002 we are obligated to pay to Connetics a royalty of 0.25% of our
U.S. net sales for ACTIMMUNE until our cumulative U.S. net sales surpass
$1 billion. Thereafter, we are obligated to pay a royalty of 0.5% of our U.S.
net sales.

Until April 2004, Connetics has an option under the Assignment and Option
Agreement to obtain the exclusive, royalty-free right to commercialize ACTIMMUNE
for dermatological diseases in the United States. If Connetics exercises its
option, then it will make one-time payments to us upon the occurrence of
milestones. Connetics also has a first right of negotiation to become our
marketing partner for the sale of ACTIMMUNE to dermatologists for diseases that
are not primarily dermatological in origin.

ALZA CORPORATION (AMPHOTEC)

In January 2001, InterMune acquired worldwide rights to Amphotec
(Amphocil-Registered Trademark- outside the United States) from ALZA. The
transaction terms include an upfront license fee of $9.0 million, milestone
payments based upon sales levels and the development of Amphotec in combination
with ACTIMMUNE, and royalties payable upon net sales levels.

MEDICAL COLLEGE OF WISCONSIN (PCRV PROTEIN)

In March 1999, we entered into a License Agreement with the Medical College
of Wisconsin under which we received exclusive, worldwide rights to technology
owned by the college relating to PcrV protein. We are obligated to pay the
college one-time payments on the occurrence of milestone events, as well as a
royalty on the sales of products covered by this technology. We have also
entered into a research agreement with the college to sponsor basic research
relating to pseudomonas aeruginosa.

PANORAMA RESEARCH, INC. (STAPHYLOCOCCUS AUREUS)

In January 2000, we entered into a Sponsored Research and License Agreement
with Panorama Research, Inc. under which we received exclusive, worldwide rights
to technology owned by Panorama relating to staphylococcus aureus, as well as to
technology to be developed by Panorama pursuant to the staphylococcus aureus
research program that we support. We will pay to Panorama one-time payments on
the occurrence of milestone events, as well as a royalty on the sales of
products covered by this technology. Within 30 days of our receipt of FDA
approval of a new drug application for a product, we are obligated to pay
$500,000 to Panorama.

MANUFACTURING

We contract with qualified third-party manufacturers to produce our
products. This manufacturing strategy enables us to direct financial resources
to the development and commercialization of products rather than diverting
resources to establishing a manufacturing infrastructure.

GENENTECH, INC. SUPPLY AGREEMENT (ACTIMMUNE)

Genentech manufactures and formulates bulk active ingredient and fills and
finishes ACTIMMUNE destined for commercial supply. Our supply agreement with
Genentech expires in May 2001. We expect that the supply of commercial product
that we will be receiving from Genentech will meet our needs for commercial
supply through March 2002. Genentech has an option to extend the term of this
agreement. We are negotiating such an extension of the supply agreement with
Genentech to obtain additional commercial supply through a later date, if
necessary.

10

BOEHRINGER INGELHEIM SUPPLY AGREEMENT (ACTIMMUNE)

We have a supply agreement with Boehringer Ingelheim to manufacture both
clinical and commercial supply of ACTIMMUNE. Boehringer Ingelheim currently
manufactures and formulates bulk active ingredient and fills and finishes
ACTIMMUNE for clinical supply.

Boehringer Ingelheim is pursuing qualification by the FDA to manufacture
ACTIMMUNE for our commercial supply to enable it to succeed Genentech as our
commercial supplier of ACTIMMUNE. We believe that the transition of commercial
supply from Genentech to Boehringer Ingelheim will not cause any delays in
supply of commercial product. We expect that the FDA will approve Boehringer
Ingelheim as a manufacturer of commercially marketed ACTIMMUNE by the fourth
quarter of 2001. However, there can be no assurance whether or when the FDA will
approve Boehringer Ingelheim as a manufacturer of commercially marketed
ACTIMMUNE or that Boehringer Ingelheim will be able to supply us with sufficient
quantities of commercial ACTIMMUNE by March 2002. If we do not receive
sufficient quantities of commercial ACTIMMUNE from Boehringer Ingelheim and are
unable to extend the term of our Genentech supply agreement, we may experience a
shortage of commercial supply, which would have a material and adverse effect on
our revenues, business and financial prospects.

The supply agreement with Boehringer Ingelheim also generally provides for
the mutual exclusive supply by Boehringer Ingelheim and purchase by us of
interferon gamma-1b. If we do not purchase a minimum amount of interferon
gamma-1b, we pay a penalty. If Boehringer Ingelheim is not able to supply all of
our requirements for interferon gamma-1b, we may choose an additional
manufacturer. Under this agreement, we are required to maintain until the end of
2001 a standby letter of credit in the amount of approximately $530,000. The
amount of the standby letter of credit approximates 20% of the total payment
obligation under this agreement with respect to Boehringer Ingelheim's
establishment of comparability between its product and Genentech's. The term of
the agreement expires on December 31, 2006 and automatically renews for
successive terms, except if either Boehringer Ingelheim or we choose not to
continue at a defined time prior to the expiration of the then current term.

PATENTS AND PROPRIETARY RIGHTS

The proprietary nature of, and protection for, our products, product
candidates, processes and know-how are important to our business. We plan to
prosecute and defend aggressively our patents and proprietary technology. Our
policy is to patent or in-license the technology, inventions and improvements
that we consider important to the development of our business. We also rely on
trade secrets, know-how and continuing innovation to develop and maintain our
competitive position.

We have acquired proprietary rights in the United States, Canada, and Japan
to develop, make, use and sell interferon gamma-1b, ACTIMMUNE, in particular
fields in connection with our license agreement with Genentech. This license
agreement covers 12 U.S. patents and 9 corresponding Japanese patents. We have
acquired proprietary rights worldwide to develop, make, use and sell
Amphotec/Amphocil in particular fields in connection with our acquisition of the
product from Alza Corporation. In January 2001, Alza assigned to us 3 U.S.
patents and 14 corresponding non-U.S. patents. We have also licensed a patent
application in the area of pseudomonas vaccine methods and have filed patent
applications for treatment methods and compositions concerning interferon gamma
and for compositions concerning staphylococcus infections. We expect to continue
to protect our proprietary technology with additional filings as appropriate.

The degree of future protection for our proprietary rights is uncertain, and
we cannot ensure that:

- we were the first to make the inventions covered by each of our pending
patent applications;

- we were the first to file patent applications for these inventions;

11

- others will not independently develop similar or alternative technologies
or duplicate any of our technologies;

- any of our pending patent applications will result in issued patents;

- any patents issued to us or our collaborators will provide a basis for
commercially viable products or will provide us with any competitive
advantages or will not be challenged by third parties;

- we will develop additional proprietary technologies that are patentable;
or

- the patents of others will not have an adverse effect on our business.

We attempt to ensure that our technology does not infringe the rights of
others. We are not aware of any asserted or unasserted claims that our
technology violates the proprietary rights of others. We are aware that the
principal investigator of Phase I and Phase II clinical trials of interferon
gamma-1b for the treatment of idiopathic pulmonary fibrosis has filed a patent
application in several European countries claiming the use of interferon
gamma-1b for this disease. We do not believe that a corresponding patent
application has been filed in the United States. Further, we believe it is
unlikely that the investigator could successfully obtain patent protection in
the United States for the use of interferon gamma-1b to treat idiopathic
pulmonary fibrosis. However, we cannot be certain that the investigator or a
third party has not filed and will not obtain a U.S. patent claiming the use of
interferon gamma-1b for the treatment of idiopathic pulmonary fibrosis or any of
the other diseases for which we are developing ACTIMMUNE. If a third party were
issued a patent that blocked our ability to commercialize ACTIMMUNE for any of
the diseases we are targeting, we and our collaborators would be subject to
legal action, unless we obtained a license under that patent in order to
continue our commercialization efforts for those diseases. We are aware of a
U.S. patent that pertains to the use of interferon gamma to treat ovarian
cancer. The term for this patent expires in August 2007. Although we will not be
promoting ACTIMMUNE for ovarian cancer until we receive an FDA marketing
approval, we are negotiating a license with the patent holder to obtain
marketing rights under this patent. If we are unable to license such rights, the
patent holder would be able to block our ability to commercialize ACTIMMUNE for
the treatment of ovarian cancer until the patent expires in August 2007.

COMPETITION

ACTIMMUNE is the only FDA-approved therapy for each of chronic granulomatous
disease and severe, malignant osteopetrosis. There is no currently available
effective therapy for the treatment of idiopathic pulmonary fibrosis. We are not
aware of any ongoing U.S. clinical trial for this disease other than our Phase
III clinical trial.

We believe that the primary competition for ACTIMMUNE in serious infectious
diseases such as mycobacterial and systemic fungal infections consists of:

- the potential development of new generations of advanced antibiotics and
anti-fungal agents that successfully treat these diseases; and

- the current treatment regimens, which may be less effective in many cases,
but cost substantially less than the current price for ACTIMMUNE.

The primary competition for ACTIMMUNE in cystic fibrosis are the
FDA-approved drugs marketed by Genentech and Chiron Corporation and the multiple
programs in development for cystic fibrosis.

In the United States, the primary competition for Amphotec is
Ambisome-Registered Trademark-, marketed by Gilead Sciences, Inc., and
Abelcet-Registered Trademark-, marketed by Elan Corporation, plc. Outside the
United States, the

12

primary competition for Amphotec/Amphocil is also Ambisome and Abelcet, which
are marketed by various distributors.

SALES AND MARKETING

We are marketing ACTIMMUNE in the United States for the treatment of chronic
granulomatous disease and severe, malignant osteopetrosis. We are marketing
Amphotec worldwide for the treatment of invasive aspergillosis. We have 38 field
specialists who market and sell ACTIMMUNE and Amphotec for FDA-approved
diseases, and educate physicians and increase their awareness of ACTIMMUNE and
Amphotec. We intend to increase the number of field specialists to 60 by
mid-2001. We sponsor speaker programs, medical symposia and continuing medical
education programs regarding ACTIMMUNE. Our marketing efforts also consists of
direct mailings to physicians, advertisements, our ACTIMMUNE.com website, which
contains product and disease information for physicians and patients, and
physician trade shows.

GOVERNMENTAL REGULATION AND PRODUCT APPROVAL

The FDA and comparable regulatory agencies in state and local jurisdictions
and in foreign countries impose substantial requirements upon the clinical
development, manufacture, and marketing of pharmaceutical products. These
agencies and other federal, state and local entities regulate research and
development activities and the testing, manufacture, quality control, safety,
effectiveness, labeling, storage, record keeping, approval, advertising and
promotion of our products. We believe that our products will be regulated as
biologics by the FDA.

The process required by the FDA before our products, or new diseases for
approved products, may be marketed in the United States generally involves the
following:

- preclinical laboratory and animal tests;

- submission of an investigational new drug, or IND, application, which must
become effective before clinical trials may begin;

- adequate and well-controlled human clinical trials to establish the safety
and efficacy of the proposed drug for its intended use; and

- FDA approval of a new biologics license application, or BLA, supplement.

The testing and approval process requires substantial time, effort, and
financial resources, and we cannot be certain that any new approvals for our
products will be granted on a timely basis, if at all.

Prior to commencing a clinical trial, we must submit an IND application to
the FDA. The IND automatically becomes effective 30 days after receipt by the
FDA, unless the FDA, within the 30-day time period, raises concerns or questions
about the conduct of the trial. In such a case, the IND sponsor and the FDA must
resolve any outstanding concerns before the clinical trial can begin. Our
submission of an IND may not result in FDA authorization to commence a clinical
trial. Further, an independent institutional review board at the medical center
proposing to conduct the clinical trial must review and approve the plan for any
clinical trial before it commences.

Human clinical trials are typically conducted in three sequential phases
that may overlap:

- Phase I: The drug is initially introduced into healthy human subjects or
patients and tested for safety, dosage tolerance, absorption, metabolism,
distribution and excretion.

13

- Phase II: Involves studies in a limited patient population to identify
possible adverse effects and safety risks, to determine the efficacy of
the product for specific targeted diseases and to determine dosage
tolerance and optimal dosage.

- Phase III: When Phase II evaluations demonstrate that a dosage range of
the product is effective and has an acceptable safety profile, Phase III
trials are undertaken to further evaluate dosage, clinical efficacy and to
further test for safety in an expanded patient population at
geographically dispersed clinical study sites.

- In the case of products for severe or life-threatening diseases such as
idiopathic pulmonary fibrosis, the initial human testing is often
conducted in patients rather than in healthy volunteers. Because these
patients already have the target disease, these studies may provide
initial evidence of efficacy traditionally obtained in Phase II trials,
and thus these trials are frequently referred to as Phase I/II trials.

We may not successfully complete Phase I, Phase II or Phase III testing of
ACTIMMUNE or Amphotec within any specific time period, if at all. Furthermore,
the FDA or an institutional review board or the sponsor may suspend a clinical
trial at any time on various grounds, including a finding that the subjects or
patients are being exposed to an unacceptable health risk.

The results of product development, preclinical studies and clinical studies
are submitted to the FDA as part of a BLA, or a BLA supplement, for approval of
a new disease if the product is already approved for a disease. The FDA may deny
a BLA or BLA supplement if the applicable regulatory criteria are not satisfied,
or it may require additional clinical data and/or a second Phase III pivotal
clinical trial. For example, the FDA may require us to complete a second
Phase III pivotal trial before granting us a BLA for idiopathic pulmonary
fibrosis or multidrug-resistant tuberculosis. Even if additional clinical data
is submitted, the FDA may ultimately decide that the BLA or BLA supplement does
not satisfy the criteria for approval. Once issued, the FDA may withdraw product
approval if compliance with regulatory standards is not maintained or if
problems occur after the product reaches the market. In addition, the FDA may
require testing and surveillance programs to monitor the effect of approved
products which have been commercialized, and the FDA has the power to prevent or
limit further marketing of a product based on the results of these
post-marketing programs.

The FDA's fast track program is intended to facilitate the development and
expedite the review of drugs intended for the treatment of serious or
life-threatening diseases and that demonstrate the potential to address unmet
medical needs for such conditions. Under this program, the FDA can, for example,
review portions of a BLA for a fast track product before the entire application
is complete, thus potentially beginning the review process at an earlier time.
We cannot guarantee that the FDA will grant any of our requests for fast track
designation, that any fast track designation would affect the time of review, or
that the FDA will approve the BLA submitted for any of our drug candidates,
whether or not fast track designation is granted. Additionally, the FDA's
approval of a fast track product can include restrictions on the product's use
or distribution, such as permitting use only for specified medical procedures or
limiting distribution to physicians or facilities with special training or
experience. Approval of fast track products can be conditional with a
requirement for additional clinical studies after approval.

Satisfaction of FDA requirements or similar requirements of state, local and
foreign regulatory agencies typically takes several years and the actual time
required may vary substantially, based upon the type, complexity and novelty of
the product or disease. Government regulation may delay or prevent marketing of
potential products or new diseases for a considerable period of time and to
impose costly procedures upon our activities. We cannot be certain that the FDA
or any other regulatory agency will grant additional approvals for ACTIMMUNE or
Amphotec on a timely basis, if at all. Success in early stage clinical trials
does not ensure success in later stage clinical trials. Data obtained from
clinical activities is not always conclusive and may be susceptible to varying

14

interpretations, which could delay, limit or prevent regulatory approval. Even
if a product receives regulatory approval, the approval may be significantly
limited to specific diseases and dosages. Further, even after regulatory
approval is obtained, later discovery of previously unknown problems with a
product may result in restrictions on the product or even complete withdrawal of
the product from the market. Delays in obtaining, or failures to obtain
additional regulatory approvals for ACTIMMUNE would harm our business. In
addition, we cannot predict what adverse governmental regulations may arise from
future U.S. or foreign governmental action.

Any products manufactured or distributed by us pursuant to FDA approvals are
subject to continuing regulation by the FDA, including record-keeping
requirements and reporting of adverse experiences with the drug. Drug
manufacturers and their subcontractors are required to register their
establishments with the FDA and certain state agencies, and are subject to
periodic unannounced inspections by the FDA and certain state agencies for
compliance with good manufacturing practices, which impose certain procedural
and documentation requirements upon us and our third party manufacturers. We
cannot be certain that we or our present or future suppliers will be able to
comply with the good manufacturing practices regulations and other FDA
regulatory requirements.

Physicians may prescribe drugs for uses that are not described in the
product's labeling for uses that differ from those tested by us and approved by
the FDA. Such off-label uses are common across medical specialties. Physicians
may believe that such off-label uses are the best treatment for many patients in
varied circumstances. The FDA does not regulate the behavior of physicians in
their choice of treatments. The FDA does, however, restrict manufacturer's
communications on the subject of off-label use. Companies cannot actively
promote FDA-approved drugs for off-label uses, but may in some circumstances
disseminate to physicians articles published in peer-reviewed journals, like THE
NEW ENGLAND JOURNAL OF MEDICINE, that discuss off-label uses of approved
products.

The FDA's policies may change and additional government regulations may be
enacted which could prevent or delay regulatory approval of our potential
products or new diseases for ACTIMMUNE or Amphotec. We cannot predict the
likelihood, nature, or extent of adverse governmental regulation that might
arise from future legislative or administrative action, either in the United
States or abroad.

Under the Orphan Drug Act, the FDA may grant orphan drug designation to
drugs intended to treat a rare disease or condition, which is generally a
disease or condition that affects fewer than 200,000 individuals in the United
States. Orphan drug designation must be requested before submitting a BLA. After
the FDA grants orphan drug designation, the generic identity of the therapeutic
agent and its potential orphan use are disclosed publicly by the FDA. Orphan
drug designation does not convey any advantage in or shorten the duration of the
regulatory review and approval process. If a product that has orphan drug
designation subsequently receives FDA approval for the disease for which it has
such designation, the product is entitled to orphan exclusivity for seven years,
i.e., the FDA may not approve any other applications to market the same drug for
the same disease, except in very limited circumstances, for seven years. We
intend to file for orphan drug designation for those ACTIMMUNE or Amphotec
diseases that meet the criteria for orphan exclusivity. Although obtaining FDA
approval to market a product with orphan drug exclusivity can be advantageous,
there can be no assurance that it would provide us with a material commercial
advantage.

RESEARCH AND DEVELOPMENT

We direct financial resources efficiently to goal-oriented projects by
reducing the time and infrastructure spent on research and development. We do
not conduct in-house discovery research. Instead, we contract these activities
to qualified third-party research institutions such as academia or private
contract labs. We have two contracted discovery research programs. The first is
with the Medical College of Wisconsin and is focused on the development of
monoclonal antibodies against pseudomonas aeruginosa. The other program is in
collaboration with Panorama Research and is focused on the development of
peptides that block staphylococcus aureus infections.

15

EMPLOYEES

As of March 15, 2001, we had 91 full-time employees. Of the full-time
employees, 32 were engaged in research and development, and 59 were engaged in
sales, general and administrative positions. We believe our relations with our
employees are good.

Stockholders and potential investors in shares of our stock should carefully
consider the following risk factors, in addition to other information and risk
factors in this report. We are identifying these risk factors as important
factors that could cause our actual results to differ materially from those
contained in any written or oral forward-looking statements made by or on behalf
of InterMune. We are relying upon the safe-harbor for forward-looking
statements, and any such statements made by or on behalf of InterMune are
qualified by reference to the following cautionary statements, as well as to
those set forth elsewhere in this report.

RISKS RELATED TO OUR BUSINESS

WE ARE AN EARLY STAGE COMPANY AND MAY NOT SUCCEED IN OUR DEVELOPMENT EFFORTS.

We commenced operations in 1998 and are at an early stage of development. We
have incurred significant losses to date, and our revenues have been limited
primarily to sales of ACTIMMUNE for chronic granulomatous disease. Although we
are developing ACTIMMUNE for the treatment of idiopathic pulmonary fibrosis,
multidrug-resistant tuberculosis, cryptococcal meningitis and cystic fibrosis,
ACTIMMUNE will not be marketed for any of these diseases before 2003, if at all.
Although Amphotec/Amphocil is an approved product, we do not believe that it
will provide significant revenue to us before 2003, if at all.

IF WE FAIL TO OBTAIN THE CAPITAL NECESSARY TO FUND OUR OPERATIONS, WE WILL BE
UNABLE TO SUCCESSFULLY EXECUTE OUR BUSINESS PLAN.

We believe that existing cash, investment securities and cash flow from
sales of ACTIMMUNE will be sufficient to meet our capital requirements under our
current business plan through at least the end of 2003. However, our business
plan could change. We also expect capital outlays and operating expenditures to
increase over the next several years as we expand our infrastructure and
research and development activities. We may need to spend more money than
currently expected because we may need to change our product development plans
or product offerings to address difficulties with clinical studies or preparing
for commercial sales for new diseases. We have no committed sources of capital
and do not know whether additional financing will be available when needed, or,
if available, that the terms will be favorable to our stockholders or us. If
additional funds are not available, we may be forced to delay or terminate
clinical trials, curtail operations or obtain funds through collaborative and
licensing arrangements that may require us to relinquish commercial rights or
potential markets or grant licenses on terms that are not favorable to us. If
adequate funds are not available, we will not be able to execute our business
plan.

16

IF WE CONTINUE TO INCUR NET LOSSES FOR A PERIOD LONGER THAN WE ANTICIPATE, WE
MAY BE UNABLE TO CONTINUE OUR BUSINESS.

We have lost money since we commenced operations in August 1998, and our
accumulated deficit was approximately $36.7 million at December 31, 2000. We
expect to incur substantial additional net losses for at least the next three to
five years. The extent of our future net losses and the timing of our
profitability are highly uncertain, and we may never achieve profitable
operations. We are planning to expand the number of diseases for which ACTIMMUNE
and Amphotec may be marketed, and this expansion will require significant
expenditures. To date, we have generated revenues primarily through the sale of
ACTIMMUNE for chronic granulomatous disease. After consideration of the direct
costs of marketing ACTIMMUNE for chronic granulomatous disease and severe,
malignant osteopetrosis, and royalties we must pay to Genentech on sales of
ACTIMMUNE, we do not currently generate any significant operating profits on
those sales. Even if we succeed in developing ACTIMMUNE and Amphotec for
additional diseases, we expect to incur net losses for at least the next three
to five years and expect that these net losses will increase as we expand our
research and development activities. If the time required to achieve
profitability is longer than we anticipate, we may not be able to continue our
business.

IF OUR CLINICAL TRIALS FAIL TO DEMONSTRATE THAT ACTIMMUNE IS SAFE AND EFFECTIVE
FOR THE TREATMENT OF ADDITIONAL DISEASES, THE FDA AND FOREIGN REGULATORY
AUTHORITIES WILL NOT PERMIT US TO MARKET ACTIMMUNE FOR THOSE DISEASES.

In order to obtain the regulatory approvals we need for the additional
diseases we have targeted, we must conduct clinical trials to establish that
ACTIMMUNE is safe and effective for treating them. Clinical trials are an
expensive and lengthy process and the results are inherently unpredictable.
ACTIMMUNE may not be successful in clinical trials intended to confirm and
expand upon those trials. In addition, the commencement or completion of our
clinical trials may be delayed or halted for various reasons, including that:

- ACTIMMUNE is not effective, or physicians think that ACTIMMUNE is not
effective, for a particular disease;

- a country's regulatory authority does not approve our clinical trial
protocol;

- patients experience severe adverse side effects during or following
treatment;

- patients die during a clinical trial because their disease is too advanced
or because they experience medical problems that are not related to
ACTIMMUNE;

- a sufficient quantity of patients do not enroll in the clinical trials at
the rate we expect; and

- the supply of ACTIMMUNE is not sufficient to treat the patients in some or
all of the proposed clinical trials.

In addition, the FDA and foreign regulatory authorities have substantial
discretion in the approval process.The FDA may deny a BLA or BLA supplement if
the applicable regulatory criteria are not satisfied, or it may require
additional clinical data and/or a second Phase III pivotal clinical trial. For
example, the FDA may require us to complete a second Phase III pivotal trial
before granting us a BLA for idiopathic pulmonary fibrosis or
multidrug-resistant tuberculosis. The FDA and foreign regulatory authorities may
also impose ongoing requirements for post-marketing studies.

IF THE FDA WITHDRAWS ITS APPROVAL FOR OUR PRODUCTS FOR ANY DISEASE FOR WHICH
THEY HAVE BEEN APPROVED, WE COULD NO LONGER MARKET OUR PRODUCTS FOR THAT
DISEASE, AND OUR REVENUES WOULD SUFFER.

The manufacturing, distribution, advertising and marketing of
pharmaceuticals are subject to extensive regulation. Any new disease approval
that we receive could include significant restrictions on the use or marketing
of our products. Later discovery of previously unknown problems with either of
our products or their manufacturing process or facility may result in further
restrictions, including

17

withdrawal of the product from the market. Our existing approvals for chronic
granulomatous disease, severe, malignant osteopetrosis, invasive aspergillosis
and any new approval for any other disease that we have targeted, if granted,
could be withdrawn for failure to comply with regulatory requirements. In
addition, governmental authorities could seize our inventory of ACTIMMUNE or
Amphotec/Amphocil or force us to recall any product already in the market if we
fail to comply with strictly enforced FDA or other governmental regulations.

WE COULD LOSE OUR RIGHT TO MARKET AND DEVELOP ACTIMMUNE IF OUR LICENSE AGREEMENT
WITH GENENTECH TERMINATES.

We license ACTIMMUNE from Genentech. If Genentech terminates its agreement
with us, we will have no further rights to utilize the patents or trade secrets
covered by the agreement to develop and market ACTIMMUNE. This license also has
the following risks:

- if we breach our agreement with Genentech, Genentech could terminate the
license, and we could lose our rights to develop and market ACTIMMUNE; and

- if Genentech fails to maintain the intellectual property licensed to us,
we may lose our rights to develop and market ACTIMMUNE and may be forced
to incur substantial additional costs to maintain the intellectual
property or to force Genentech to do so.

DISCOVERIES OR DEVELOPMENTS OF NEW TECHNOLOGIES BY ESTABLISHED DRUG COMPANIES OR
OTHERS MAY MAKE ACTIMMUNE OR AMPHOTEC OBSOLETE.

Our commercial opportunities will be reduced or eliminated if our
competitors develop and market products that are more effective, have fewer or
less severe adverse side effects or are less expensive than ACTIMMUNE or
Amphotec for any disease that they target. With respect to our drug discovery
programs in pseudomonas aeruginosa and staphylococcus aureus, other companies
have product candidates or research programs that are further advanced in
development than any of our potential products and may result in effective,
commercially successful products. Even if we are successful in developing
effective drugs, our products may not compete effectively with these products or
other successful products. Researchers are continually learning more about
diseases, which may lead to new technologies for treatment. Our competitors may
succeed in developing and marketing products either that are more effective than
those that we may develop, alone or with our collaborators, or that are marketed
before any products we develop are marketed.

Our competitors include fully integrated pharmaceutical companies and
biotechnology companies that currently have drug and target discovery efforts,
as well as universities and public and private research institutions. Many of
the organizations competing with us have substantially greater capital
resources, larger research and development staffs and facilities, greater
experience in drug development and in obtaining regulatory approvals and greater
marketing capabilities than we do.

EVEN IF REGULATORY AUTHORITIES APPROVE ACTIMMUNE FOR THE TREATMENT OF THE
DISEASES WE ARE TARGETING, ACTIMMUNE MAY NOT BE COMMERCIALLY SUCCESSFUL.

ACTIMMUNE is an expensive drug, and we anticipate that the annual cost for
treatment under each of the diseases for which we are seeking approval will be
significant. Market acceptance of and demand for ACTIMMUNE will depend largely
on the following factors:

- acceptance by physicians and patients of ACTIMMUNE as a safe and effective
therapy for a particular disease;

- pricing of alternative products, for example, many of the existing
treatments for mycobacterial infections cost less than ACTIMMUNE;

- relative convenience and ease of administration of ACTIMMUNE; and

- prevalence and severity of adverse side effects associated with ACTIMMUNE.

18

IF THIRD-PARTY PAYORS WILL NOT PROVIDE COVERAGE OR REIMBURSE PATIENTS FOR
ACTIMMUNE, OUR REVENUES AND PROFITABILITY WILL SUFFER.

Our ability to commercialize ACTIMMUNE in additional diseases may depend in
part on the extent to which coverage and reimbursement for ACTIMMUNE will be
available from:

- governmental payors, such as Medicare and Medicaid;

- private health insurers, including managed care organizations; and

- other third-party payors.

Significant uncertainty exists as to the coverage and reimbursement status
of pharmaceutical products. If governmental and other third-party payors do not
provide adequate coverage and reimbursement levels for ACTIMMUNE, the market
acceptance of ACTIMMUNE will be reduced, and our sales will suffer.

THE PRICING AND PROFITABILITY OF OUR PRODUCTS MAY BE SUBJECT TO CONTROL BY THE
GOVERNMENT AND OTHER THIRD-PARTY PAYORS.

The continuing efforts of governmental and other third-party payors to
contain or reduce the cost of health care through various means may adversely
affect our ability to successfully commercialize products. For example, in some
foreign markets, pricing and profitability of prescription pharmaceuticals are
subject to governmental control. In the United States, we expect that there will
continue to be federal and state proposals to implement similar governmental
control. In addition, increasing emphasis on managed care in the United States
will continue to put pressure on the pricing of pharmaceutical products. Cost
control initiatives could decrease the price that we would receive for
ACTIMMUNE, Amphotec/Amphocil or any other products in the future, which would
reduce our revenues and profitability.

ALTHOUGH WE PLAN TO RELAUNCH AMPHOTEC, THE PRODUCT MAY NOT BE COMMERCIALLY
SUCCESSFUL.

We plan to relaunch Amphotec during 2001. However, market acceptance of and
demand for Amphotec will depend largely on the following factors:

- Acceptance by physicians of Amphotec as a safe and effective therapy for
invasive aspergillosis;

- Pricing of alternative products; and

- Prevalence and severity of side effects associated with Amphotec.

IF PRODUCT LIABILITY LAWSUITS ARE BROUGHT AGAINST US, WE MAY INCUR SUBSTANTIAL
LIABILITIES.

The testing, marketing, and sale of medical products entail an inherent risk
of product liability. If losses exceed our liability insurance coverage, we may
incur substantial liabilities. Whether or not we were ultimately successful in
product liability litigation, such litigation would consume substantial amounts
of our financial and managerial resources, and might result in adverse
publicity, all of which would impair our business. We may not be able to
maintain our clinical trial insurance or product liability insurance at an
acceptable cost, if at all, and this insurance may not provide adequate coverage
against potential claims or losses.

IF WE ARE UNABLE TO CONTRACT WITH THIRD PARTIES TO MANUFACTURE ACTIMMUNE OR
AMPHOTEC IN SUFFICIENT QUANTITIES, ON A TIMELY BASIS OR AT AN ACCEPTABLE COST,
WE MAY BE UNABLE TO MEET DEMAND FOR ACTIMMUNE OR AMPHOTEC AND MAY LOSE POTENTIAL
REVENUES.

ACTIMMUNE

We do not have the resources, facilities or experience to manufacture
ACTIMMUNE ourselves. Completion of our clinical trials and commercialization of
ACTIMMUNE for new diseases requires access to, or development of, facilities to
manufacture a sufficient supply of ACTIMMUNE. The FDA

19

must approve manufacturing facilities for ACTIMMUNE. We depend on third parties
with FDA-approved manufacturing facilities for the manufacture of ACTIMMUNE for
pre-clinical, clinical, and commercial purposes. We presently rely on Genentech
for the manufacture of commercially marketed ACTIMMUNE and on Boehringer
Ingelheim Austria GmbH for the supply of ACTIMMUNE for clinical trials.

Our supply agreement with Genentech expires in May 2001. Genentech has an
option to extend the term of this agreement, and we are negotiating such an
extension with Genentech to obtain additional commercial supply through a later
date, if neccessary. We expect that the supply of commercial product that we
will be receiving from Genentech will meet our needs for commercial supply
through March 2002. Boehringer Ingelheim is also pursuing qualification by the
FDA to manufacture ACTIMMUNE for our commercial supply to enable Boehringer
Ingelheim to succeed Genentech as our commercial supplier of ACTIMMUNE. We
believe that the transition from Genentech to Boehringer Ingelheim will not
cause any delays in supply of commercial product. We expect that the FDA will
approve Boehringer Ingelheim as a manufacturer of commercially marketed
ACTIMMUNE by the fourth quarter of 2001. However, there can be no assurance if
or when the FDA will approve Boehringer Ingelheim as a manufacturer of
commercially marketed ACTIMMUNE or that Boehringer Ingelheim will be able to
supply us with sufficient quantities of commercial ACTIMMUNE by April 2002. If
we do not receive sufficient quantities of commercial ACTIMMUNE from Boehringer
Ingelheim and are unable to extend the term of our Genentech supply agreement,
we will experience a shortage of commercial supply, which would have a material
and adverse effect on our revenues, business and financial prospects.

Our manufacturing strategy also presents the following risks:

- Before we can obtain approval for a new disease for ACTIMMUNE, we must
demonstrate to the FDA's satisfaction that the drug used in the clinical
trials is substantially equivalent to the commercial drug manufactured by
Genentech.

- Delays in increasing existing manufacturing capacity to meet our needs for
multiple clinical trials could delay clinical trials, regulatory
submissions, and commercialization of ACTIMMUNE.

- Our manufacturers of ACTIMMUNE are subject to ongoing periodic inspection
by the FDA and corresponding state agencies for compliance with strictly
enforced good manufacturing practices regulations and similar foreign
standards, and we do not have control over our third-party manufacturers'
compliance with these regulations and standards.

- If we need to contract with other manufacturers, the FDA and foreign
regulatory authorities must approve these manufacturers prior to our use
of their products. This would require new testing and compliance
inspections. The new manufacturers would need to become educated in, or
themselves develop, substantially equivalent processes necessary for the
production of ACTIMMUNE.

- If market demand for ACTIMMUNE increases suddenly, our current
manufacturers might not be able to fulfill our commercial needs, which
would require us to seek new manufacturing arrangements and may result in
substantial delays in meeting market demand.

- If market demand for ACTIMMUNE is less than our purchase obligations to
our manufacturers, we may incur substantial penalties.

- Our supply arrangements with our manufacturers may be seriously
interrupted.

- We may not have intellectual property rights, or may have to share
intellectual property rights, to any improvements in the manufacturing
processes or new manufacturing processes for ACTIMMUNE.

20

Any of these factors could delay clinical trials or commercialization of
ACTIMMUNE for new diseases, interfere with current sales, entail higher costs
and result in our being unable to effectively sell ACTIMMUNE.

AMPHOTEC

We do not have the resources, facilities or experience to manufacture
Amphotec ourselves. We must depend on third parties with FDA-approved
manufacturing facilities for the manufacture of Amphotec for pre-clinical,
clinical and commercial purposes. We presently have an agreement with Ben Venue
Laboratories, Inc. for the manufacture of Amphotec for all purposes. This
agreement expires in December 2001. We are negotiating with Ben Venue to renew
the agreement. If we are unable to renew the agreement with Ben Venue, or enter
into a supply agreement with another manufacturer, on commercially reasonable
terms, if at all, we will experience a shortage of supply or decreased profits,
either of which would have a material and adverse effect on our revenues,
business and financial prospects.

BECAUSE IT IS DIFFICULT AND COSTLY TO PROTECT OUR PROPRIETARY RIGHTS, WE MAY NOT
BE ABLE TO PROTECT THEM.

Our commercial success will depend in part on obtaining and maintaining
patent protection on our products and successfully defending these patents
against third party challenges. The patent positions of pharmaceutical and
biotechnology companies can be highly uncertain and involve complex legal and
factual questions. No consistent policy regarding the breadth of claims allowed
in biotechnology patents has emerged to date. Accordingly, we cannot predict the
breadth of claims that may be allowed in other companies' patents. In addition,
we could incur substantial costs in litigation if we are required to defend
against patent suits brought by third parties or if we initiate these suits.

Others may have filed and in the future may file patent applications
covering interferon gamma-1b and its uses and other products in our development
program. For example, we are aware that the principal investigator of Phase I/II
and Phase II clinical trials of interferon gamma-lb for the treatment of
idiopathic pulmonary fibrosis has filed a patent application in several European
countries claiming the use of interferon gamma-lb for this disease. We cannot be
certain that the investigator or any other third party has not filed and will
not obtain a U.S. patent claiming the use of interferon gamma-lb for the
treatment of idiopathic pulmonary fibrosis or any of the other diseases for
which we are developing ACTIMMUNE. If a third party were issued a patent that
blocked our ability to commercialize ACTIMMUNE for any of the diseases we are
targeting, a legal action could result.

Any legal action against our collaborators or us claiming damages and
seeking to enjoin commercial activities relating to the affected products and
processes could, in addition to subjecting us to potential liability for
damages, require our collaborators or us to obtain a license to continue to
manufacture or market the affected products and processes. We cannot predict
whether we or our collaborators would prevail in any of these actions or that
any license required under any of these patents would be made available on
commercially acceptable terms, if at all. We believe that there may be
significant litigation in our industry regarding patent and other intellectual
property rights.

In addition, we generally do not control the patent prosecution of
technology that we license from others. Accordingly, we are unable to exercise
the same degree of control over this intellectual property as we would exercise
over technology that we own.

We rely on trade secrets to protect technology where we believe patent
protection is not appropriate or obtainable. However, trade secrets are
difficult to protect. While we require employees, academic collaborators and
consultants to enter into confidentiality agreements, which generally provide
that proprietary information developed or inventions conceived during the
relationship shall be our exclusive property, we may not be able to adequately
protect our trade secrets or other proprietary information.

21

Our research collaborators and scientific advisors have rights to publish
data and information in which we have rights. If we cannot maintain the
confidentiality of our technology and other confidential information in
connection with our collaborations, then our ability to receive patent
protection or protect our proprietary information will be impaired.

FAILURE TO ATTRACT, RETAIN AND MOTIVATE SKILLED PERSONNEL AND CULTIVATE KEY
ACADEMIC COLLABORATIONS WILL DELAY OUR PRODUCT DEVELOPMENT PROGRAMS AND OUR
BUSINESS DEVELOPMENT EFFORTS.

We have 91 employees as of March 15, 2001, and our success depends on our
continued ability to attract, retain and motivate highly qualified management
and scientific personnel and on our ability to develop relationships with
leading academic scientists. Competition for personnel and academic
collaborations is intense. We are highly dependent on our current management and
key scientific and technical personnel, including W. Scott Harkonen, Chief
Executive Officer, President and Chairman of our board of directors, as well as
the other principal members of our management. Our success will depend in part
on retaining the services of our existing management and key personnel and
attracting and retaining new highly qualified personnel. In addition, we may
need to hire additional personnel and develop additional collaborations as we
continue to expand our research and development activities. We do not know if we
will be able to attract, retain or motivate personnel or cultivate academic
collaborations. Our inability to hire, retain or motivate qualified personnel or
cultivate academic collaborations would harm our business and hinder the planned
expansion of our business.

WE RELY ON THIRD PARTIES TO CONDUCT CLINICAL TRIALS FOR ACTIMMUNE, AND THOSE
THIRD PARTIES MAY NOT PERFORM SATISFACTORILY.

If third parties do not successfully carry out their contractual duties or
meet expected deadlines, we will not be able to obtain regulatory approvals for
ACTIMMUNE and will not be able to successfully commercialize ACTIMMUNE for new
diseases. We do not have the ability to independently conduct clinical studies
for ACTIMMUNE, and we rely on third parties to perform this function. If these
third parties do not perform satisfactorily, we may not be able to locate
acceptable replacements or enter into favorable agreements with them, if at all.

OTHER RISKS

IF OUR OFFICERS, DIRECTORS AND LARGEST STOCKHOLDERS CHOOSE TO ACT TOGETHER, THEY
MAY BE ABLE TO CONTROL OUR MANAGEMENT AND OPERATIONS, ACTING IN THEIR BEST
INTERESTS AND NOT NECESSARILY THOSE OF OTHER STOCKHOLDERS.

As of March 1, 2001, our directors, executive officers and principal
stockholders and their affiliates beneficially owned approximately 26.7% of our
issued and outstanding common stock. Accordingly, they collectively may have the
ability to determine the election of all of our directors and to determine the
outcome of most corporate actions requiring stockholder approval. They may
exercise this ability in a manner that advances their best interests and not
necessarily those of other stockholders.

Provisions of our amended and restated certificate of incorporation and
bylaws, as well as provisions of Delaware law, could make it more difficult for
a third party to acquire us, even if doing so would benefit our stockholders.
These provisions:

- establish a classified board of directors so that not all members of our
board may be elected at one time;

- authorize the issuance of "blank check" preferred stock that could be
issued by our board of directors to increase the number of outstanding
shares and hinder a takeover attempt;

- limit who may call a special meeting of stockholders;

- prohibit stockholder action by written consent, thereby requiring all
stockholder actions to be taken at a meeting of our stockholders; and

22

- establish advance notice requirements for nominations for election to our
board of directors or for proposing matters that can be acted upon at
stockholder meetings.

In addition, Section 203 of the Delaware General Corporation Law, which
prohibits business combinations between us and one or more significant
stockholders unless specified conditions are met, may discourage, delay or
prevent a third party from acquiring us.

OUR STOCK PRICE MAY BE VOLATILE, AND YOUR INVESTMENT IN OUR STOCK COULD DECLINE
IN VALUE.

The trading price of our common stock has been and is likely to continue to
be extremely volatile. Our stock price could be subject to wide fluctuations in
response to a variety of factors, including the following:

- actual or anticipated variations in quarterly operating results;

- adverse results or delays in clinical trials;

- announcements of technological innovations by us or our competitors;

- new products or services offered by us or our competitors;

- changes in financial estimates by securities analysts;

- announcements of significant acquisitions, strategic partnerships, joint
ventures or capital commitments by us or our competitors;

- significant sales of our common stock; and

- other events or factors, many of which are beyond our control.

In addition, the stock market in general, and the Nasdaq National Market and
biotechnology companies in particular, have experienced extreme price and volume
fluctuations that have often been unrelated or disproportionate to the operating
performance of these companies. Broad market and industry factors may negatively
affect the market price of our common stock, regardless of actual operating
performance. In the past, following periods of volatility in the market price of
a company's securities, securities class action litigation has often been
instituted against companies. This type of litigation, if instituted, could
result in substantial costs and a diversion of management's attention and
resources, which would harm our business.

SUBSTANTIAL SALES OF SHARES MAY IMPACT THE MARKET PRICE OF OUR COMMON STOCK.

If our stockholders sell substantial amounts of our common stock, including
shares issued upon the exercise of outstanding options, the market price of our
common stock may decline. These sales also might make it more difficult for us
to sell equity or equity-related securities in the future at a time and price
that we deem appropriate. We are unable to predict the effect that sales may
have on the then prevailing market price of our common stock. As of March 1,
2001, we had outstanding 23,909,654 shares of common stock. Of these shares,
9,305,208 shares are freely tradable without restriction or further regulation.

The remaining 14,604,446 shares of common stock held by existing
stockholders may not be sold publicly unless they are registered under the
Securities Act or have been or are sold pursuant to Rule 144 or another
exemption from registration. These shares will become eligible for public resale
at various times subject to volume limitations.

We have filed a registration statement covering shares of common stock
issuable upon exercise of options and other grants pursuant to our stock plans.
In addition, the holders of common stock that are parties to our amended and
restated investor rights agreements are entitled to registration rights.

26

BOARD COMPOSITION

Our board of directors consists of seven directors, and Dr. Harkonen is the
chairman. Our board of directors is divided into three classes:

- Class I directors, Mr. Higgins and Dr. Hockmeyer, whose term will expire
at the annual meeting of stockholders to be held in 2001;

- Class II directors, Drs. Engleman, Harkonen and Healy, whose term will
expire at the annual meeting of stockholders to be held in 2002; and

- Class III directors, Messrs. Leff and Simon, whose term will expire at the
annual meeting of stockholders to be held in 2003.

At each annual meeting of stockholders, the successors to directors whose
terms will then expire will be elected to serve from the time of election and
qualification until the third annual meeting following election. Any additional
directorships resulting from an increase in the number of directors will be
distributed among the three classes so that, as nearly as possible, each class
will consist of one-third of the directors. This classification of our board of
directors may have the effect of delaying or preventing changes in control or
management of us.

ITEM 2. PROPERTIES

Our facilities currently consist of approximately 8,000 square feet of
office space located at 1710 Gilbreth Road, Suite 301, Burlingame, California,
which is leased to us until 2004 and approximately 2,800 square feet of office
space at 875 Mahler Road, Suite 118, Burlingame, California, which is leased to
us until August 2001. In June 2001, we expect to move into our new corporate
headquarters at 3280 Bayshore, in Brisbane, California. In December 2000, we
entered into a ten- (10) year lease for this 56,000 square foot building. We
plan to use approximately 35,000 square feet for offices and 3,000 square feet
for laboratory and research purposes and to sublease the remaining 18,000 square
feet to a short-term tenant. We believe that this facility has sufficient space
to accommodate the expansion of our operations until at least 2004.

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

OVERVIEW

InterMune develops and commercializes innovative products for the treatment
of serious pulmonary and infectious diseases and cancer. We have two marketed
products, growing product revenues, and advanced-stage clinical programs. In the
United States, we market our lead product, ACTIMMUNE, for the treatment of
chronic granulomatous disease, a life-threatening congenital disorder of the
immune system, and severe, malignant osteopetrosis, a life threatening
congenital disorder causing an overgrowth of bony structures. In January 2001,
we began marketing Amphotec worldwide for the treatment of invasive
aspergillosis, a life-threatening systemic fungal infection.

Since our inception, we have incurred significant losses and, as of
December 31, 2000, we had an accumulated deficit of $36.7 million.

Our expenses have consisted primarily of costs incurred in research and
development, sales and marketing and from general and administrative costs
associated with our operations. We expect our research and development expenses
to increase in the future as we expand our clinical trial activities for our
target diseases. Our sales and marketing expenses will increase as we continue
to commercialize ACTIMMUNE. Expansion of our operations will also add to our
expenses. As a result, we expect to incur losses for the foreseeable future.

We have a limited history of operations and anticipate that our quarterly
and annual results of operations will fluctuate for the foreseeable future due
to several factors, including market acceptance of current or new products,
patent conflicts, the introduction of new products by our competitors, the
timing and extent of our research and development efforts, and the timing of
significant orders. Our limited operating history makes accurate prediction of
future operating results difficult or impossible.

On June 27, 2000, we entered into the Revenue Adjustment Agreement with
Connetics Corporation by which we acquired from Connetics the rights to those
ACTIMMUNE revenues under the baseline that we did not already own (established
by the Transition Agreement with Connetics, dated April 27, 1999). Beginning
with the three-month period ended June 30, 2000, we recorded all ACTIMMUNE
revenues and related expenses that had been previously transacted for Connetics.
These sales, costs of sales and accounts receivable were recorded by us on a net
basis, in the accompanying financial statements for the period from
February 25, 1998 (inception) to December 31, 1998, the year ended December 31,
1999 and the three-month period ended March 31, 2000. Such sales, costs of sales
and accounts receivable were not previously subject to the risks and rewards of
ownership by us. The Revenue Adjustment Agreement terminated the Transition
Agreement, Collaboration Agreement and Section 5.2 of the Assignment Agreement
with Connetics.

DEFERRED STOCK COMPENSATION

In connection with the grant of stock options to employees, we recorded
deferred stock compensation totaling $8.6 million and $5.6 million in the fiscal
years ended December 31, 2000 and 1999, respectively.

Deferred stock compensation for options granted to employees has been
determined as the difference between the deemed fair value of our common stock
for financial reporting purposes on the date such options were granted and the
applicable exercise prices. Such amount is included as a reduction of
stockholders' equity and is being amortized using the graded vesting method over
the

30

vesting period of the individual options, which is generally five years. This
graded vesting method provides for vesting of portions of the overall award at
interim dates and results in higher vesting in earlier years than straight-line
vesting. We recorded amortization of deferred stock compensation of
$6.7 million and $345,000 for the years ended December 31, 2000 and 1999,
respectively. At December 31, 2000, we had a total of $7.2 million to be
amortized over the remaining vesting periods of the stock options.

RESULTS OF OPERATIONS

COMPARISON OF YEARS ENDED DECEMBER 31, 2000 AND 1999

REVENUE. Total revenues were $11.2 million and $556,000 for the years ended
December 31, 2000 and 1999, respectively. The revenues in 1999 represented our
portion of ACTIMMUNE sales that exceeded the annual contractual baseline
established with Connetics in effect at that time. On June 27, 2000, we
terminated the annual baseline agreement with Connetics for ACTIMMUNE sales
below a contractual baseline. Beginning with the three-month period ending
June 30, 2000, our revenues reflect all sales for ACTIMMUNE. The revenues in
2000 represent all sales from April 1, 2000 to December 31, 2000 of ACTIMMUNE in
the United States and sales outside the United States related to a supply
arrangement. For all of 1999 and the three-month period ended March 31, 2000,
sales transacted for Connetics below the annual contractual baseline were
recorded on a net basis, which was zero, and any amounts in excess of net
revenues less costs to produce and market were paid to Connetics.

COST OF GOODS SOLD. We recognized expenses related to cost of goods sold of
$5.0 million and $240,000 for the years ended December 31, 2000 and 1999,
respectively. Cost of goods sold includes all product cost of goods sold
including manufacturing costs, royalties and distribution costs associated with
our revenues. The increase in 2000 was due entirely to costs associated with
increased product sales volumes.

AMORTIZATION OF PRODUCT REVENUE RIGHTS. We recorded a total of $1.8 million
and $0 for the years ended December 31, 2000 and 1999, respectively. On
June 28, 2000, we purchased rights to all of the ACTIMMUNE revenues and related
expenses that we had previously transacted for Connetics. The amortization of
those rights is expensed based upon product units shipped under the previous
contractual unit baseline for the year 2000.

RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses were
$20.8 million and $3.0 million for the years ended December 31, 2000 and 1999,
respectively, representing an increase of 601% or $17.8 million. Of the
increased costs in the year 2000, a total of $4.2 million is related to non-cash
stock-based compensation and the amortization of deferred stock compensation.
The remaining increase in 2000 was due primarily to increased costs for clinical
trial expenses for ACTIMMUNE in new disease indications and the expenses
associated with our transfer of ACTIMMUNE to an additional manufacturing
facility. These costs have been recorded as research and development expenses as
the new facility is not yet operational. We expect research and development
expenses to increase significantly over the next several years.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses were $16.2 million and $2.7 million for the years ended
December 31, 2000 and 1999, respectively, representing an increase of 508%, or
$13.5 million. Of the increased costs in 2000, a total of $4.0 million is
related to the amortization of deferred stock compensation. The remaining
increase in 2000 is attributable primarily to increased staffing and related
expenses necessary to manage the expansion of our operations. We believe that
selling, general and administrative expenses will continue to increase in
absolute dollars as a result of the anticipated expansion of our administrative
staff and increased marketing and selling expenses for ACTIMMUNE in its approved
diseases.

31

ACQUIRED PRE-FDA APPROVAL RIGHTS. We recorded a total of $0 and
$1.1 million for the years ended December 31, 2000 and 1999, respectively. The
amount paid in 1999 was for the acquisition of additional development rights for
ACTIMMUNE from Genentech.

INTEREST INCOME. Interest income totaled $8.5 million and $240,000 for the
years ended December 31, 2000 and 1999, respectively. The increase in interest
income in 2000 was a result of increased cash available for investments as a
result of the private and public financing activities during the year.

INTEREST EXPENSE. Interest expense totaled $191,000 and $186,000 for the
years ended December 31, 2000 and 1999, respectively. The amount in 2000 is
imputed interest on the obligations to Connetics. Interest expense in 1999 was
primarily due to the royalty obligations owed to Genentech that were paid off in
full upon the close of our initial public offering in March 2000.

DEEMED DIVIDEND UPON ISSUANCE OF CONVERTIBLE PREFERRED STOCK. We recorded a
deemed dividend of $27.8 million in January 2000, upon the issuance of 4,966,361
shares of Series B redeemable convertible preferred stock. At the dates of
issuance, we believed the per share price of $5.59 represented the fair value of
the preferred stock and was in excess of the deemed fair value of our common
stock. Subsequent to the commencement of our initial public offering process, we
re-evaluated the deemed fair value of our common stock and determined it to be
$12.60 to $14.40 per share. Accordingly, the aggregate proceeds of
$27.8 million fair value is deemed to be the equivalent of a preferred stock
dividend. We recorded the deemed dividend at the date of issuance by offsetting
charges and credits to additional paid-in capital of $27.8 million, without any
effect on total stockholders' equity. The amount increased the loss applicable
to common stockholders in the calculation of basic net loss per share the year
ended December 31, 2000.

PROVISION FOR INCOME TAXES. Due to operating losses and the inability to
recognize the benefits therefrom, there is no provision for income taxes for the
years ended December 31, 2000 and 1999.

As of December 31, 2000, we had federal net operating loss carryforwards of
approximately $22.0 million. The net operating loss carryforwards will expire at
various dates beginning in 2018 through 2020, if not utilized. Utilization of
the net operating losses may be subject to a substantial annual limitation due
to the "change in ownership" provisions of the Internal Revenue Code of 1986 and
similar state provisions. The annual limitation may result in the expiration of
net operating losses before utilization.

COMPARISON OF YEARS ENDED DECEMBER 31, 1999 AND 1998

REVENUE. We recognized product sales of $556,000 for the year ended
December 31, 1999, compared to no product sales of ACTIMMUNE for the period from
February 25, 1998 (inception) to December 31, 1998. The sales in 1999
represented our portion of ACTIMMUNE sales that exceeded the annual contractual
baseline established with Connetics, which increases nominally each year, until
2002, when discontinued. Sales transacted for Connetics were recorded on a net
basis, which was zero, because any amounts in excess of net revenues less costs
to produce and market were paid to Connetics. We made payments to Connetics in
1999 of $1.4 million, and no payments were made in 1998. Please see Note 3 of
our financial statements.

Connetics was entitled to net sales of ACTIMMUNE up to a predetermined
baseline for the period from January 15, 1999 through December 31, 2001, less
associated cost of goods sold and marketing expenses. The predetermined baseline
was preset for each calendar year under our agreement.

32

COST OF GOODS SOLD. We recognized expenses related to cost of goods sold of
$240,000 for the year ended December 31, 1999. We recognized no cost of goods
sold for the period from February 25, 1998 (inception) to December 31, 1998
because we had no product sales. Cost of goods sold includes all product cost of
goods sold, royalties, and distribution costs associated with our revenues.

RESEARCH AND DEVELOPMENT EXPENSES. Research and development expenses were
$3.0 million and $1.2 million for the year ended December 31, 1999, and for the
period from February 25, 1998 (inception) to December 31, 1998, respectively.
The increased in expenses for 1999 resulted primarily from increased costs for
clinical trial study expenses for ACTIMMUNE in additional disease indications
and a full 12-month period of operations.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES. Selling, general and
administrative expenses were $2.7 million and $892,000 for the year ended
December 31, 1999, and for the period from February 25, 1998 (inception) to
December 31, 1998, respectively. The increase in expenses for 1999 was primarily
attributed to increased costs for additional personnel and a full 12-month
period of operations.

ACQUIRED PRE-FDA APPROVAL RIGHTS. We recorded a total of $1.1 million and
$4.0 million for the year ended December 31, 1999 and for the period from
February 25, 1998 (inception) to December 31, 1998, respectively. The expense in
1999 was in connection with the acquisition of additional development rights for
ACTIMMUNE. The expense for the period from February 25, 1998 (inception) to
December 31, 1998 was in connection with the sublicensed rights of ACTIMMUNE.
Please see Note 3 of our financial statements.

INTEREST INCOME. Interest income increased to a total of $240,000 in 1999
from $55,000 for the period from February 25, 1998 (inception) to December 31,
1998. The increase was due to higher average balances of cash and cash
equivalents and short-term investments in 1999, resulting from the investment of
the net proceeds from the sale of Series A-2 convertible preferred stock in
April 1999.

INTEREST EXPENSE. Interest expense totaled $186,000 for the year ended
December 31, 1999 and we had no interest expense for the period from
February 25, 1998 to December 31, 1998. For the year ended December 31, 1999, we
recognized a total of $111,000 for imputed interest expense on our long-term
obligation to Connetics and $75,000 interest expense on the royalty payable
obligation to Genentech for the year ended December 31, 1999. The obligation to
Connetics was incurred in April 1999, as part of our collaboration agreement
with them.

LIQUIDITY AND CAPITAL RESOURCES

Since inception, we have funded our operations since inception through sales
of equity securities, net contributions from Connetics and sales of our
products. At December 31, 2000, we had available cash, cash equivalents and
available-for-sale investments of $194.5 million. Our cash reserves are held in
a variety of interest-bearing instruments including obligations of U.S.
government agencies, high-grade corporate bonds, commercial paper and money
market accounts. Cash in excess of immediate requirements is invested with
regard to liquidity and return and, wherever possible, we seek to minimize the
potential effects of concentration and degrees of risk.

Net cash used in operations for the year ended December 31, 2000, totaled
$19.5 million compared to $3.1 million for the same period in 1999 and
$1.3 million for the period from February 25, 1998 (inception) to December 31,
1998. A net loss of $24.2 million for the year ended December 31, 2000, included
non-cash charges of $6.7 million for the amortization of deferred stock
compensation, $2.7 million related to the issuance of equity instruments for
non-cash benefits, $160,000 for depreciation and amortization and $144,000 for
the accretion of obligations payable to Connetics.

33

Net cash used for financing activities included capital expenditures for
equipment and leasehold improvements to support the Company's operations of
$1.0 million, $30,000 and $0 in 2000 and 1999, and for the period from
February 25, 1998 (inception) to December 31, 1998, respectively.

Net cash used by investing activities in the year 2000 was $146.8 million
compared to net cash provided of $1.9 million in 1999, and net cash used of
$2.4 million in 1998. In 2000, the net cash used was primarily due to the net
purchases of short-term available-for-sale investments. In 1999, the net cash
provided resulted primarily from the net maturities of short-term investments
used to fund operations. The net cash used in investing activities in 1998 was
primarily due to the net purchases of short-term available-for-sale investments.

Net cash provided by financing activities for the year ended December 31,
2000 totaled $210.7 million, and represents $25.2 million in net proceeds from
the sale of Series B convertible preferred stock to investors in January 2000,
$115.0 million in net proceeds from the sale of common stock in our initial
public offering, $71.1 million in net proceeds from a private placement of
common stock which closed on August 18, 2000, $373,000 from stock option
exercises and $85,000 received under our employee stock purchase plan offset by
$1.0 million paid to Connetics upon the close of our initial public offering. We
recorded this payment as a "return of capital to parent."

Working capital of $194.7 million at December 31, 2000 increased from
$1.2 million at December 31, 1999. The increase in working capital was primarily
due to proceeds from our financing activities.

On June 27, 2000, through the Revenue Adjustment Agreement, we paid to
Connetics $5.2 million in cash in conjunction with the purchase from Connetics
of all the rights to ACTIMMUNE that we did not already own. The amount paid to
Connetics included $807,000 as the prepayment of obligations owed to them and
$4.4 million for product revenue rights that was capitalized as a current asset
and will be amortized based upon product units shipped over the next 12 months
of operations. Prior to this transaction, Connetics had retained the risks and
rewards of ownership including inventory and collection risk with approximately
the first $6.5 million in ACTIMMUNE sales in the United States in each of the
years 2000 and 2001. We have a final payment of approximately $943,000 due to
Connetics by March 31, 2001, and have recorded the net present value of this
payment as of December 31, 2000 of $912,000.

At December 31, 1999, we had deferred payment of the royalties due to
Genentech for 1999 of approximately $1.9 million through a series of
interest-bearing promissory notes that became due upon the close of our initial
public offering on March 29, 2000. Genentech did not exercise its option to
convert these promissory notes into shares of our common stock, and in
March 2000, we paid the $1.9 million of deferred royalties owed to Genentech.

On January 7 and January 27, 2000, we issued 4,876,916 aggregate shares of
Series B redeemable convertible preferred stock at $5.59 per share for aggregate
proceeds of $27.3 million. We incurred $1.4 million of issuance costs.

On January 7, 2000, pursuant to the terms of the Collaboration Agreement
with Connetics, we issued to Connetics 89,445 shares of series B-1 convertible
preferred stock. This stock issuance has been reflected as a return of capital
to Connetics in the accompanying December 31, 1999 financial statements as we
had concluded that the event triggering the issuance (the closure of the
Series B financing) was probable at December 31, 1999.

On March 29, 2000, we closed our initial public offering in which we sold
6,250,000 shares of our common stock at a price of $20.00 per share, raising
$125.0 million in gross proceeds. We received offering proceeds of
$115.0 million, net of $8.8 million in underwriters discounts and commissions
and $1.2 million in related expenses. On the close of the initial public
offering, each outstanding share of our preferred stock was converted into one
share of common stock.

34

On August 18, 2000, we closed a private financing, in which we sold
2,000,000 shares of our common stock at a price of $38.00 per share, raising
$76.0 million in gross proceeds. We received net proceeds of $71.1 million after
deducting placement agent fees of $4.6 million and estimated related expenses of
$0.3 million.

We believe our existing cash, cash equivalents and available-for-sale
securities, together with cash flows from our operations will be sufficient to
fund our operating expenses, debt obligations and capital requirements through
at least the end of 2003. However, our capital requirements may increase in
future periods and as a result, we may require additional funds. We may attempt
to raise additional funds through equity or debt financings, collaborative
arrangements with corporate partners or from other sources. We have no
commitments for any additional financings and additional funding may not be
available to finance our operations when needed or, if available, the terms for
obtaining such funds may not be favorable or may result in dilution to our
stockholders.

As of December 31, 2000 and 1999, our principal commitments relating to our
obligation under non-cancelable operating leases were $35.3 million and
$1.2 million, respectively. The increase in commitments at December 31, 2000 is
due to additional lease obligations on an additional facility.

Effective as of January 1, 2001, we acquired worldwide rights to Amphotec
from ALZA Corporation. The transaction terms include an upfront license fee of
$9.0 million, milestone payments based upon sales levels and the development of
Amphotec in combination with ACTIMMUNE, and royalties payable upon net sales
levels. Amphotec is an FDA-approved lipid-complexed form of amphotericin B
indicated for the treatment of invasive aspergillosis, a life-threatening fungal
infection.

ITEM 7A QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

We maintain an investment portfolio of depository accounts, master notes and
liquidity optimized investment contracts. The securities in our investment
portfolio are not leveraged, are classified as available-for-sale and are, due
to their very short-term nature, subject to minimal interest rate risk. We
currently do not hedge interest rate exposure. If market interest rates were to
increase by 100 basis points, or 1%, from December 31, 2000 levels, the
estimated fair value of our investment portfolio would decline by approximately
$372,000. At December 31, 2000, the average maturity of our available-for-sale
securities was 91 days.

The primary objective of the Company's investment activities is to preserve
principal while at the same time maximize yields without significantly
increasing risk. To achieve this objective, the Company invests its excess cash
in debt instruments of the U.S. Government and its agencies and high-quality
corporate issuers, and, by policy, restricts its exposure to any single
corporate issuer by imposing concentration limits. To minimize the exposure due
to adverse shifts in interest rates, the Company maintains investments at an
average maturity of generally less than two years.

The table below presents the principal amounts and weighted-average interest
rates by year of maturity for the Company's investment portfolio:

INTERMUNE PHARMACEUTICALS, INC.

NOTES TO FINANCIAL STATEMENTS

1. ORGANIZATION

OVERVIEW

InterMune Pharmaceuticals, Inc. ("InterMune" or the "Company") develops and
commercializes innovative products for the treatment of serious pulmonary and
infectious diseases and cancer. The Company has the exclusive license rights in
the United States to ACTIMMUNE (Interferon gamma-1b) Injection for a range of
indications, including chronic granulomatous disease, osteopetrosis, idiopathic
pulmonary fibrosis, cancer, mycobacterial infections, systemic fungal infections
and cystic fibrosis. The Company has active development programs underway for
these indications, several of which are in mid- or advanced-stage human testing,
known as clinical trials. The FDA has approved ACTIMMUNE for the treatment of
chronic granulomatous disease, and the Company markets and sells ACTIMMUNE in
the United States for this disease. In February 2000, the FDA approved the
Company's biologics license application for ACTIMMUNE for the treatment of
severe, malignant osteopetrosis, and the Company markets and sells ACTIMMUNE in
the United States for this disease.

The Company was incorporated on February 25, 1998 in the State of California
and commenced operations as a wholly owned subsidiary of Connetics Corporation
("Connetics") in May of 1998. Beginning in May 1998, Connetics contributed
certain development rights and intellectual property valued at $4 million, cash
of $6 million and unreimbursed operating costs of $0.3 million to InterMune,
then its wholly-owned subsidiary. The value of the development rights and
intellectual property contributed was determined by the amount Connetics had
paid Genentech for those same rights in May 1998. The entire value of these
rights had been allocated to in-process research and development by Connetics
and has also been reflected in InterMune's statement of operations for the
period from February 25, 1998 (inception) through December 31, 1998, as acquired
pre-FDA approval rights with a corresponding increase to capital contributed by
parent. The determination of the portion of the value of the rights allocable to
in-process research and development was made based upon the discounted cash
flows of the rights acquired projected over a ten year period, and included the
costs of research and development efforts necessary to prove efficacy of the
molecule to which the rights pertain. The Company reincorporated in Delaware on
March 21, 2000.

On April 27, 1999, the Company obtained venture capital funding and was
reorganized pursuant to the Series A-1 and A-2 Preferred Stock Purchase
Agreement (see Note 3). At the time of the reorganization, approximately
$4.7 million of the $10.3 million of capital originally contributed by Connetics
to InterMune, its wholly owned subsidiary, was returned to Connetics in the form
of cash. The Company also recorded a liability for $3.0 million to be paid to
Connetics over the next several years in cash and stock (see Note 3), the
present value of which was recorded as a return of capital to Connetics. The
Company cancelled all of the 11.2 million shares of Series A preferred stock it
had originally issued to Connetics. Connetics also received 960,000 shares of
InterMune's Series A-1 preferred stock and net sales of ACTIMMUNE (as well as
incurring associated costs and expenses) up to a baseline amount through
December 2001, both in exchange for the remaining $3.4 million of Connetics'
contributed capital. See Note 3 for a more complete description of the
April 27, 1999 agreements. At that time, Connetics retained approximately 9.0%
ownership in the Company.

On June 27, 2000, the Company entered into the Revenue Adjustment Agreement
with Connetics Corporation by which the Company acquired from Connetics the
rights to those ACTIMMUNE revenues under the baseline that the Company did not
already own (established by the Transition Agreement, dated April 27, 1999).
Beginning with the three-month period ended June 30, 2000, the Company recorded
all ACTIMMUNE revenues and related expenses that had been previously

43

INTERMUNE PHARMACEUTICALS, INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

1. ORGANIZATION (CONTINUED)
transacted for Connetics. These sales, costs of sales and amounts receivable
were recorded by the Company on a net basis, in the accompanying financial
statements for the period from February 25, 1998 (inception) to December 31,
1998, the year ended December 31, 1999 and the three-month period ended
March 31, 2000. Such sales, costs of sales and accounts receivable were not
subject to the risks and rewards of ownership by the Company. The Revenue
Adjustment Agreement terminated the Transition Agreement, Collaboration
Agreement and Section 5.2 of the Assignment Agreement with Connetics.

BASICS OF ACCOUNTING

The accompanying financial statements include the operations of InterMune
for the period from February 25, 1998 to April 27, 1999, as a wholly owned
subsidiary of Connetics. The Company's financial statements include all costs of
doing business during the period it was a wholly owned subsidiary. Separate
accounting records for the Company were maintained during this period, but were
included in the consolidated financial statements of Connetics. Connetics
provided InterMune with certain information services, accounting activities,
employee benefit administration and research and development services as
described in Note 3. InterMune is charged the actual time incurred plus an
allocation of overhead costs based upon time incurred. The Company believes the
allocation methodology is reasonable.

Prior to the date of InterMune's incorporation, February 25, 1998, Connetics
had licensed certain rights to ACTIMMUNE for dermatological indications from
Genentech and has retained an option to such dermatological rights. In
April 1998, after the incorporation of InterMune, Connetics licensed the rights
to ACTIMMUNE from Genentech for different indications, including the treatment
of serious infectious and pulmonary diseases, infectious diseases and cancer,
for $4.0 million of Connetics stock. Those rights were subsequently sublicensed
to InterMune in exchange for InterMune convertible preferred stock. On
April 27, 1999, InterMune issued to Genentech 875,000 shares of InterMune
Series A preferred stock valued at $1.1 million in exchange for additional
ACTIMMUNE development rights in Japan and a reduction of future royalties on
potential ACTIMMUNE net product revenues through its sublicense agreement with
Connetics.

During the year ended December 31, 2000, the Company emerged from its
development stage and commenced generating revenue. As such, its financial
statements are no longer prepared on a development stage basis.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

USE OF ESTIMATES

The preparation of financial statements in conformity with accounting
principles generally accepted in the United States requires management to make
estimates and assumptions that affect the reported amounts reported in the
financial statements and accompanying notes. Actual results could differ from
those estimates.

CASH, CASH EQUIVALENTS AND AVAILABLE-FOR-SALE SECURITIES

Cash and cash equivalents consist of highly liquid investments with original
maturities when purchased of less than three months. Investments with maturities
beyond three months at the date of

44

INTERMUNE PHARMACEUTICALS, INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
acquisition and that mature within one year from the balance sheet date are
considered to be short-term investments. Cash equivalents and available-for-sale
securities are carried at fair value, with unrealized gains and losses, net of
tax, reported as a separate component of stockholders' equity. The estimated
fair value amounts have been determined by the Company using available market
information. The cost of securities sold is based on the specific identification
method.

CONCENTRATION OF RISK

Cash equivalents and investments are financial instruments which potentially
subject the Company to concentration of risk to the extent recorded on the
balance sheet. Management of the Company believes it has established guidelines
for investment of its excess cash relative to diversification and maturities
that maintain safety and liquidity.

In 2000, three wholesale customers accounted for 33%, 25%, and 21% of total
net product sales. In 1999, the same three wholesale customers accounted for
29%, 23% and 9% of total net product sales.

InterMune may need to rely solely on Genentech, through March 2002, for the
commercial supply of ACTIMMUNE for sales. Any extended interruption in the
supply of ACTIMMUNE could result in the failure to meet customer demand.

INVENTORIES

Inventories consist principally of finished good products and are stated at
the lower of cost or market. Cost is determined by the first-in, first-out
(FIFO) method.

PROPERTY AND EQUIPMENT

Property and equipment are stated at cost and depreciated using the
straight-line method over the estimated useful lives of the assets, generally 3
to 5 years. Leasehold improvements are amortized over the shorter of the lease
term or the estimated useful life of the assets.

IMPAIRMENT OF LONG-LIVED ASSETS

In accordance with SFAS No. 121, Accounting for the Impairment of Long-Lived
Assets and for Long-Lived Assets to be disposed of, if indicators of impairment
exist, the Company assesses the recoverability of the affected long-lived assets
by determining whether the carrying value of such assets can be recovered
through undiscounted future operating cash flows. If impairment is indicated,
the Company will measure the amount of such impairment by comparing the carrying
value of the asset to the present value of the expected future cash flows
associated with the use of the asset. To date, no such indicators of impairment
have been identified.

FAIR VALUE OF FINANCIAL INSTRUMENTS

Financial instruments, including cash and cash equivalents, accounts
receivable, accounts payable, accrued liabilities, and long-term royalty
payable, are carried at cost, which management believes approximates fair value
because of the short-term maturity of these instruments.

45

INTERMUNE PHARMACEUTICALS, INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
REVENUE RECOGNITION

Revenues from product sales are recognized upon shipment when title passes
to the customer, net of allowances for estimated returns, rebates and
chargebacks. The Company is obligated to accept from customers the return of
pharmaceuticals that have reached their expiration date. The Company monitors
product ordering cycles and actual returns, product date codes and wholesale
inventory levels to estimate potential product return rates. The Company
believes that its product return reserves are adequate. The Company has not
experienced any significant returns of expired product.

Sales and related costs of sales and accounts receivable for sales below the
baseline amount were transacted for Connetics under the Transition Agreement
(see Note 3). For sales below the baseline amount, any amounts in excess of net
revenues less costs to produce and market are paid to Connetics under the
Transition Agreement. These sales, costs of sales and amounts receivable are
recorded by us on a net basis, which is equivalent to zero in the accompanying
financial statements. Thus, the Company does not record receivables or product
returns for sales transacted for Connetics in their financial statements. Such
sales, costs of sales and accounts receivable are not subject to the risks and
rewards of ownership by the Company.

On June 27, 2000, the Company entered into the Revenue Adjustment Agreement
with Connetics Corporation to purchase all rights to ACTIMMUNE revenues under
the baseline that had previously been recorded by Connetics established by the
Transition Agreement, dated April 27, 1999 (see Note 3). Beginning with the
three-month period ended June 30, 2000, all ACTIMMUNE revenues and related
expenses that had been previously transacted for Connetics would now be recorded
by the Company. These sales, costs of sales and amounts receivable are on a net
basis, in the accompanying financial statements for the period from
February 25, 1998 (inception) to December 31, 1998, the year ended December 31,
1999 and the three-month period ended March 31, 2000. Such sales, costs of sales
and accounts receivable were not previously subject to the risks and rewards of
ownership by the Company. The Revenue Adjustment Agreement terminated the
Transition Agreement, Collaboration Agreement and Section 5.2 of the Assignment
Agreement with Connetics.

RESEARCH AND DEVELOPMENT COSTS

Research and development costs are expensed in the period incurred.

ADVERTISING COSTS

The Company expenses advertising costs as incurred. Advertising costs were
$581,000 for the year ended December 31, 2000, and were not material for the
year ended December 31, 1999 and for the period from February 25, 1998
(inception) to December 31, 1998.

INCOME TAXES

In accordance with SFAS No. 109, Accounting for Income Taxes, a deferred tax
asset or liability is determined based on the difference between the financial
statement and tax basis of assets and liabilities as measured by the enacted tax
rates which will be in effect when these differences reverse. The Company
provides a valuation allowance against net deferred tax assets unless, based
upon the available evidence, it is more likely than not that the deferred tax
assets will be realized.

INTERMUNE PHARMACEUTICALS, INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
PATENT COSTS

Costs related to patent prosecution are expensed as incurred, as
recoverability of such expenditures is uncertain.

STOCK-BASED COMPENSATION

As permitted by SFAS No. 123 (SFAS 123), Accounting for Stock-Based
Compensation, the Company has elected to follow Accounting Principles Board
Opinion No. 25, Accounting for Stock Issued to Employees, ("APB 25") and related
Interpretations in accounting for stock-based employee compensation. Under APB
25, if the exercise price of the Company's employee and director stock options
equals or exceeds the deemed fair value of the underlying stock on the date of
grant, no compensation expense is recognized.

When the exercise price of the employee or director stock options is less
than the deemed fair value of the underlying stock on the grant date, the
Company records deferred compensation for the difference. Deferred compensation
is being amortized using the graded vesting method over the vesting period of
the original award, generally five years. Options or stock awards issued to
non-employees are recorded at their fair value as determined in accordance with
SFAS No. 123, and are recognized over the related service period and is
periodically remeasured as the underlying options vest.

COMPREHENSIVE INCOME (LOSS)

SFAS No. 130, Reporting Comprehensive Income, requires components of other
comprehensive income, including unrealized gains or losses on the Company's
available-for-sale securities to be included in total comprehensive income
(loss). Total comprehensive loss for each of the periods presented has been
disclosed in the statement of stockholders' equity.

SEGMENT REPORTING

Company management has determined that the Company operates in one business
segment. The Company currently markets ACTIMMUNE in the United States for the
treatment of chronic granulomatous disease and severe, malignant osteopetrosis.

NET LOSS PER SHARE

In accordance with SFAS No. 128, Earnings Per Share, and SEC Staff
Accounting Bulletin (or SAB) No. 98, basic net income (loss) per share is
computed by dividing the net income (loss) for the period by the weighted
average number of common shares outstanding during the period. Shares subject to
repurchase are deducted from the outstanding shares in arriving at the weighted
average shares outstanding. Diluted net income (loss) per share is computed by
dividing the net income (loss) for the period by the weighted average number of
common and common equivalent shares outstanding during the period. Potentially
dilutive securities composed of incremental common shares issuable upon the
exercise of stock options and common shares issuable on conversion of preferred
stock, were excluded from historical diluted loss per share because of their
anti-dilutive effect. The shares to be issued upon the exercise of stock options
were 1,222,653 and 990,000 for 2000 and 1999, respectively. As of December 31,
2000 and 1999, the Company had 0 and 1,835,000 shares of convertible preferred
stock outstanding, respectively.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
Pro forma net loss per share has been computed as described above and also
gives effect to common equivalent shares arising from preferred stock that
automatically converted upon the closing of the Company's initial public
offering on March 24, 2000 (using the as-if converted method from original date
of issuance). For the year ended December 31, 1999, the pro forma shares also
reflect the common equivalent shares of preferred and common stock issued on
April 27, 1999, in connection with the reorganization as though they had been
outstanding for the entire year.

The Company's capital structure during 1998 was that of a wholly owned
subsidiary. Earnings per share data for 1998 has not been presented as the
capital structure changes that took place in 1999 made such presentation less
meaningful.

NEW ACCOUNTING PRONOUNCEMENTS

In June 1998, the FASB issued FAS 133, "Accounting for Derivative
Instruments and Hedging Activities." FAS 133, as amended, requires all
derivatives to be recorded on the balance sheet at fair value and establishes
special accounting rules for different types of hedges. FAS 133 is effective for
the Company in the first quarter of 2001 and is not expected to have a material
impact on our financial position or results of operations.

In March 2000, the FASB issued Interpretation No. 44, "Accounting for
Certain Transactions Involving Stock Compensation," (FIN 44) which provides
guidance on several implementation issues related to Accounting Principles Board
Opinion No. 25. FIN 44 became effective on July 1, 2000 and its adoption did not
have a material impact on our financial position and results of operations.

In June 2000, the Securities and Exchange Commission required the
implementation of Staff Accounting Bulletin No. 101, or SAB 101, "Revenue
Recognition in Financial Statements," by the end of calendar year 2000. SAB 101
provides guidance on applying generally accepted accounting principles to
revenue recognition issues in financial statements. We adopted SAB 101 in the
fourth quarter of 2000 and the adoption did not have a material impact on our
financial position or results of operations.

3. COLLABORATION, LICENSE, SERVICE AGREEMENTS AND OTHER TRANSACTIONS WITH
RELATED PARTIES

SUBLICENSE AND COLLABORATION AGREEMENTS

On August 21, 1998, the Company and Connetics entered into an exclusive
sublicense agreement (the sublicense agreement), pursuant to which:

(a) Connetics granted an exclusive sublicense to InterMune under the
Genentech License for ACTIMMUNE for specific indications;

(b) InterMune granted to Connetics the exclusive option to practice such
sublicensed rights in the dermatology field and;

(c) InterMune agreed to pay all amounts owed by Connetics to Genentech
related to ACTIMMUNE net sales except with respect to sales made by
Connetics in the event Connetics exercises its option. Under the
sublicense agreement, InterMune agreed to be responsible for all costs of
development and commercialization of ACTIMMUNE in the specified
indications, to pay specified payments to Genentech upon completion of
certain development and commercialization milestones, and to pay future
royalties on net annual ACTIMMUNE sales annually.

On April 27, 1999, Connetics amended the terms of its license agreement with
Genentech and obtained additional rights to ACTIMMUNE, which it simultaneously
sublicensed to InterMune.

On April 27, 1999, InterMune and Connetics also signed a Collaboration
Agreement, which was terminated in June 2000 through the Revenue Adjustment
Agreement. As a result of the sublicense, transition, service, and collaboration
agreements between InterMune and Connetics, Connetics received 960,000 shares of
InterMune's Series A-1 preferred stock, rights to net sales of ACTIMMUNE up to a
baseline amount through December 2001, less associated cost of goods sold and
marketing expenses, a nominal royalty on ACTIMMUNE net sales, and the following
payments of cash and stock, all of which

3. COLLABORATION, LICENSE, SERVICE AGREEMENTS AND OTHER TRANSACTIONS WITH
RELATED PARTIES (CONTINUED)
represent the return of a portion of Connetics' invested capital: $4.7 million
of cash on April 27, 1999; an additional $500,000 cash payment on April 27,
1999; $500,000 cash due on March 31, 2001; $1.5 million payable in installments
of cash or stock beginning on March 31, 2002 and due in full by March 31, 2004;
and an additional $1.5 million payable in stock and cash. The $500,000 due on
March 31, 2001 and the $1.5 million payable in installments of cash and stock
due through March 31, 2004 were recorded at their net present value of
$1.6 million as long-term obligations payable to Connetics as of December 31,
1999. The Company originally planned return of these capital payments to
Connetics on April 27, 1999, but the Company and Connetics agreed to defer such
payments to provide the Company with additional working capital. The Company and
Connetics agreed to increase the amounts to be repaid from approximately
$1.6 million to $2.0 million reflective of the imputed interest resulting from
the deferral at a rate of interest equal to prime plus 2%. Of the additional
$1.5 million, $500,000 was accrued in "payable to Connetics" as of December 31,
1999, in the accompanying financial statements as a reduction of capital
contributed by parent. This amount was paid to Connetics in Series B preferred
stock on January 7, 2000. The remaining additional $1 million obligation payable
in cash or InterMune stock was contingent upon a subsequent closing of a round
of financing, an initial public offering or the acquisition of the Company. This
amount was paid in cash on March 30, 2000 following the close of the Company's
initial public offering and was recorded as a return of capital.

In connection with the Revenue Adjustment Agreement, the remaining payments
due to Connetics of $500,000 and $1.5 million due on March 2001, and
March 2004, were renegotiated and $843,000 was paid on June 30, 2000, and
$943,000 is scheduled to be paid on or before March 31, 2001. The net present
value of the $943,000 obligation is $912,000 and is included in the financial
statements as of December 31, 2000. See Revenue Adjustment Agreement below.

SERVICE AGREEMENT

On October 12, 1998, the Company entered into a five-year agreement, as
amended, whereby Connetics provided to the Company certain information services,
accounting activities, facilities, employee benefit administration and research
and development services. This agreement has been terminated. The Company paid
to Connetics a total of $45,000, $1,190,000 and $362,000 for the years ended
December 31, 2000 and 1999 and for the period from February 25, 1998 (inception)
to December 31, 1998, respectively, under this agreement.

TRANSITION AGREEMENT

On April 27, 1999, the Company and Connetics entered into a three-year
Transition Agreement, which was terminated in June 2000 by the Revenue
Adjustment Agreement. The Revenue Adjustment agreement effectively transferred
certain ACTIMMUNE distribution, sales and marketing responsibilities from
Connetics to InterMune. Under the original terms of the Transition Agreement,
InterMune was obligated to:

- Provide to Connetics certain product management services including order
entry, packaging, shipping, invoicing and credit and collection activities
related to the sales of ACTIMMUNE units. Reimbursements for product
management costs are netted against the costs incurred. Total product
management costs and reimbursements from Connetics totaled $13,000,
$348,000 and $73,000 for the years ended December 31, 2000 and 1999, and
for the period from February 25, 1998 (inception) to December 31, 1998,
respectively.

- Pay Connetics each month the net sales of ACTIMMUNE up to a predetermined
baseline for the period from January 15, 1999 through December 31, 2001,
less associated cost of goods sold and marketing expenses. The
predetermined baseline is preset for each calendar year under the
agreement. The Company paid to Connetics $484,000 for the three-month
period ended March 31, 2000 and $1,357,000 under this arrangement for the
year ended December 31, 1999.

- Transition manufacturing of ACTIMMUNE from Genentech to a third-party
alternative manufacturer. In order to expedite and effect this transfer of
manufacturing, Connetics will pay a percentage of all actual costs, up to
a pre-determined cap, to complete the transfer of manufacturing of
ACTIMMUNE to a third-party alternative manufacturer. A total of
$2.7 million and $100,000 has been incurred by InterMune for the year
ended December 31, 2000 and for the period from February 28, 1998
(inception) through December 31, 1999, respectively, under this
obligation.

REVENUE ADJUSTMENT AGREEMENT

On June 27, 2000, the Company entered into the Revenue Adjustment Agreement
with Connetics Corporation by which the Company acquired from Connetics the
rights to those ACTIMMUNE revenues under the baseline that the Company did not
already own (as established by the Transition Agreement). Beginning with the
three-month period ended June 30, 2000, the Company owned and recorded all
ACTIMMUNE revenues and related expenses that had been previously transacted for
Connetics. These sales, costs of sales and accounts receivable were recorded by
the Company on a net basis, in the financial statements for the period from
February 25, 1998 (inception) to December 31, 1998, for the year ended
December 31, 1999 and for the three-months ended March 31, 2000. Such sales,
costs of sales and accounts receivable were not subject to the risks and rewards
of ownership by the Company. The Revenue Adjustment Agreement terminated the
Transition Agreement, Collaboration Agreement and Section 5.2 of the Assignment
Agreement with Connetics.

On June 27, 2000 through the Revenue Adjustment Agreement, the Company paid
to Connetics $5.2 million in cash in conjunction with the purchase of all the
rights to ACTIMMUNE from Connetics that the Company did not already own. The
amount paid to Connetics included $807,000 as the prepayment of long-term
obligations owed to them and $4.4 million for product revenue rights that

51

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

3. COLLABORATION, LICENSE, SERVICE AGREEMENTS AND OTHER TRANSACTIONS WITH
RELATED PARTIES (CONTINUED)
were recorded as a prepaid asset "Product revenue rights from Connetics." At
December 31, 2000, a total of $2.6 million of the prepaid revenue rights
remained unamortized and will be amortized based upon product units shipped over
the next 12 months of operations.

ACQUIRED PRE-FDA APPROVAL RIGHTS

InterMune licenses its development and marketing rights for ACTIMMUNE from
Genentech, Inc. Connetics had obtained these rights for ACTIMMUNE through the
Genentech License in May 1998, as amended in April 1999, and had sublicensed
these rights to InterMune through the License Agreement. On June 23, 2000,
through the Assignment and Option Agreement, Connetics assigned these rights to
InterMune. InterMune's associated rights to ACTIMMUNE include uses in chronic
granulomatous disease, osteopetrosis, pulmonary fibrosis, infectious diseases,
and cystic fibrosis. Connetics had sublicensed the rights to all of these
disease indications, except for net sales of ACTIMMUNE, up to a baseline amount
through December 2001, to InterMune. ACTIMMUNE has been approved by the FDA for
use in the treatment of chronic granulomatous disease and severe, malignant
osteopetrosis. For other indications ACTIMMUNE is in development. The Company
will incur significant costs to develop and prove efficacy in each of the other
indications.

Connetics paid Genentech $4.0 million for these rights in May 1998. The
Company valued its sublicensed rights from Connetics at $4.0 million based on
this amount paid by the Company's then parent company, Connetics. A discounted
cash flow analysis of the projected revenues and costs based on the potential
market, the estimated costs to obtain the required approvals and costs to
manufacture and market ACTIMMUNE for each indication shows a negative cash flow
for the chronic granulomatous disease indication and positive cash flows for
several of the other indications with larger patient populations. Negative cash
flows from chronic granulomatous disease result from a small U.S. market of only
400 to 1000 patients, high costs of manufacturing due to small quantities, a
royalty payable to Genentech and significant costs to market the product.
Because realization of the non-chronic granulomatous disease indications'
revenue streams is uncertain, due to the early stages of development and the
high costs to develop, the Company has expensed the $4.0 million acquisition
cost.

On April 27, 1999, InterMune acquired additional ACTIMMUNE development
rights in Japan as well as reduction of future royalties of potential ACTIMMUNE
annual net sales above a certain threshold. For these rights, InterMune issued
Genentech 875,000 shares of Series A-1 convertible preferred stock. The acquired
rights were valued at $1.1 million, the purchase price of the stock issued, as
paid by new investors in the then most recent round of financing. The acquired
development rights were estimated to have no immediate realizable value, as no
approvals for ACTIMMUNE have been obtained in Japan and significant costs will
be incurred to obtain such approvals. The reduction of the royalty rate was
similarly deemed to have no current realizable value because sales of ACTIMMUNE
for chronic granulomatous disease (the only FDA approved use of ACTIMMUNE at the
time) were not likely to exceed the annual sales threshold due to the small U.S.
market size of 400 to 1,000 patients. Accordingly, a $1.1 million charge to
acquired pre-FDA approval rights was recorded.

On January 7 and January 27, 2000, the Company issued 4,876,916 aggregate
shares of Series B redeemable convertible preferred stock at $5.59 per share for
aggregate proceeds of $27.3 million. The Company incurred approximately
$1.4 million of issuance costs.

On January 7, 2000, pursuant to the terms of the collaboration agreement
with Connetics, the Company also issued to Connetics 89,445 shares of Series B
redeemable convertible preferred stock. This stock issuance has been reflected
as a return of capital to Connetics in the accompanying December 31, 1999
financial statements as the Company had concluded that the event triggering the
issuance (the closure of the Series B financing) was probable at December 31,
1999.

The deemed fair value of the common stock at the date of issuance of the
Series B redeemable convertible preferred stock was determined to be $12.60 per
share. As a result, the Company recorded a deemed dividend of $27.8 million for
the Series B issuances in January 2000. The deemed dividend was recorded by
offsetting charges and credits to additional paid in capital, without any effect
on total stockholders' equity. The amount increased the loss applicable to
common stockholders in the calculation of basic net loss per share for the year
ended December 2000.

Upon the completion of the Company's initial public offering on March 24,
2000, all redeemable convertible preferred shares were converted on a one for
one basis into shares of common stock of the Company.

COMMON STOCK SUBJECT TO REPURCHASE

In connection with the issuance of common stock to founders and the exercise
of options pursuant to the Company's 1999 and 2000 Stock Option/Stock Issuance
Plan, employees and non-employee directors entered into restricted stock
purchase agreements with the Company. Under the terms of these agreements, the
Company has a right to repurchase any unvested shares at the original exercise
price of the shares. With continuous employment or services provided to the
company, generally the repurchase rights lapse at a rate of 20% at the end of
the first year and at a rate of 1/48th of the remaining purchased shares for
each continuous month of service thereafter. Total shares subject to repurchase
by the Company were 935,000 and 663,000 as of December 31, 2000 and 1999,
respectively.

STOCK COMPENSATION PLANS

In 1999, the Company adopted the 1999 Stock Option/Stock Issuance Plan
("1999 Plan"). The 1999 Plan provides for the granting of options to purchase
common stock and the issuance of shares of common stock, subject to Company
repurchase rights, to directors, employees and consultants. Certain options are
immediately exercisable, at the discretion of the board of directors. Shares
issued pursuant to the exercise of an unvested option are subject to the
Company's right of repurchase which lapses over periods specified by the board
of directors, generally five years from the date of grant. In March 2000, the
Company terminated all remaining unissued shares under the 1999 Plan.

In January 2000, the Board of Directors adopted the 2000 Equity Incentive
Plan and the 2000 Non-Employee Directors' Stock Option Plans. A total of
2,000,000 shares of common stock were reserved for issuance under the 2000
Equity Incentive Plan and 180,000 shares under the 2000 Non-Employee Directors'
Stock Option Plan.

The 2000 Equity Incentive Plan and 2000 Non-Employee Directors' Stock Option
Plans provide for the granting of options to purchase common stock and the
issuance of shares of common stock, subject to the Company's repurchase rights,
to directors, employees and consultants. Certain options are immediately
exercisable, at the discretion of the board of directors. Shares issued pursuant
to the exercise of an unvested option are subject to the Company's right of
repurchase which lapses over periods specified by the board of directors,
generally four years from the date of grant.

EMPLOYEE STOCK PURCHASE PLAN

To provide employees with an opportunity to purchase common stock of
InterMune through payroll deductions, InterMune established the 2000 Employee
Stock Purchase Plan. Under this plan, employees, subject to certain
restrictions, may purchase shares of common stock at 85% of the fair market
value at either the date of eligibility for enrollment or the date of purchase,
whichever is less. As of December 31, 2000, the Company had issued a total of
4,997 shares under this plan, and 195,003 shares remain available for future
issuance.

INTERMUNE PHARMACEUTICALS, INC.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

7. REDEEMABLE CONVERTIBLE PREFERRED STOCK AND STOCKHOLDERS' EQUITY (CONTINUED)
The fair value of the employees' purchase rights was estimated using the
Black-Scholes option pricing model with the following weighted average
assumptions for the year 2000; risk free interest rate of 6.0%, dividend yield
of zero, an expected volatility factor of the market price of InterMune common
stock of 90%; and an expected life of six months. The weighted-average fair
value for shares issued under the employee stock plan for 2000 was $20.74.

PRO FORMA INFORMATION

In accordance with the provisions of SFAS 123, we apply APB Opinion No. 25
and related interpretations in accounting for our stock option plans and,
accordingly, do not recognize compensation cost for options granted with
exercise prices not less than fair value on the date of grant. If we had elected
to recognize compensation cost based on the fair value of the options granted at
grant date and including stock purchases under the Employee Stock Purchase Plan
as prescribed by SFAS 123, our net loss and net loss per share numbers would
have been decreased to the pro forma amounts indicated in the table below.
Earnings per share for 1998 has not been presented as we were a wholly owned
subsidiary of Connetics during 1998.

We estimate the fair value of each option grant on the date of grant using

assumptions:

The Black-Scholes option valuation model was developed for use in estimating
the fair value of traded options that have no vesting restrictions and are fully
transferable. In addition, option valuation models require the input of highly
subjective assumptions, including the expected stock price volatility. Because
our stock options have characteristics significantly different from those of
traded options, and because changes in the subjective input assumptions can
materially affect the fair value estimate, our management does not believe that
the existing models necessarily provide a reliable single measure of the fair
value of its options. The weighted average fair value of options granted was
$19.27 in 2000 and $0.08 in 1999. No options were granted in 1998.

COMMON STOCK

On March 29, 2000, the Company closed an initial public offering, in which
the Company sold 6,250,000 shares of common stock at a price of $20.00 per
share, raising $125.0 million in gross proceeds. The Company received offering
proceeds of $115.0 million, net of $8.8 million in aggregate underwriters
discounts and commissions and $1.2 million in related expenses. On the closing
of the initial public offering, each outstanding share of preferred stock was
converted into one share of common stock.

On August 18, 2000, the Company closed a private financing, in which the
Company sold 2,000,000 shares of common stock at a price of $38.00 per share,
raising $76.0 million in gross proceeds. The Company received net proceeds of
$71.1 million after deducting placement agent fees of $4.6 million and expenses
of $0.3 million.

InterMune's Certificate of Incorporation provides for the issuance of up to
45,000,000 shares of common stock. The holder of each share of common stock has
a right to one vote.

At December 31, 2000, common stock subject to future issuance is as follows:



Outstanding common stock options............................ 1,222,653
Common stock available for grant under stock option plan.... 1,705,000

STOCK COMPENSATION

In January 2000, the Company issued 133,000 options to purchase shares of
common stock at a weighted average exercise price of $0.37 per share to
consultants in exchange for research and development consulting services.
Compensation expense is recorded as the options vest based upon the fair value
of the options, determined using the Black-Scholes pricing model.

In connection with the grant of certain stock options to employees for the
years ended December 31, 2000 and 1999, the Company recorded deferred stock
compensation of approximately $8.6 million and $5.6 million, respectively. These
amounts represent the difference between the fair value of the common stock and
the option exercise price at the date of grant. The Company recorded
amortization of deferred stock compensation of approximately $6.7 million and
$345,000 for the years ended December 31, 2000 and 1999, respectively. Deferred
stock compensation expense is being amortized using the graded vesting method
over the vesting period of the individual award, generally five years. This
method is in accordance with Financial Accounting Standards Board Interpretation
No. 28. The amortization expense relates to options awarded to employees in all
operating expense categories. The amortization of deferred stock compensation
has been separately allocated to these categories in the financial statements.
The amount of deferred compensation expense to be recorded in future periods
could decrease if options for which accrued but unvested compensation has been
recorded are forfeited.

8. INCOME TAXES

Deferred income taxes reflect the net tax effects of temporary differences
between the carrying amounts of assets and liabilities for financial reporting
and the amount used for income tax purposes. Significant components of the
Company's deferred tax assets as follows (In thousands):



DECEMBER 31, DECEMBER 31,
2000 1999
------------ ------------

Deferred tax assets:
Net operating loss carryforwards.................. $ 8,700 $ 3,000
Research and development credits.................. 440 100
Other............................................. 790 1,800
Total deferred tax assets........................... 9,930 4,900
Valuation allowance................................. (9,930) (4,900)
------- -------
Net deferred tax assets............................. $ -- $ --
======= =======


Realization of deferred tax assets is dependent upon future earnings, if
any, the timing and amount of which are uncertain. Accordingly, the net deferred
tax assets have been fully offset by a valuation allowance. The valuation
allowance increased by $5.0 million and $2.5 million during 2000 and 1999,
respectively.

As of December 31, 2000, the Company had net operating loss carryforwards
for federal income tax purposes of approximately $22.0 million which expire in
the years 2018 through 2020 and federal research and development credits of
approximately $200,000 which expire in the years 2018 through 2020.

Utilization of the Company's net operating loss may be subject to
substantial annual limitation due to the ownership change limitations provided
by the Internal Revenue Code and similar state provisions. Such an annual
limitation could result in the expiration of the net operating loss before
utilization.

9. COMMITMENTS

LEASES

In December 1999, the Company entered into a facility lease of office space
that extends through December 2004. Total rent expense under this lease was
approximately $247,000 in 2000 and $19,000 in 1999. In December 2000, the
Company entered into 10-year lease of an additional 55,000 square feet located
near the current facility.

The following is a schedule by year of future minimum lease payments at
December 31, 2000 (In thousands):

On December 18, 1999, the Company entered into a facility-operating lease
requiring a letter of credit secured by a restricted cash balance with the
Company's bank. The amount of the letter of credit approximates 12 months of
operating rent payable to the landlord of the facility.

10. SAVINGS PLAN

On May 1, 1999, the Company adopted a 401(k) defined contribution plan that
covers all full time employees, as defined, who meet certain length-of-service
requirements. Employees may contribute up to a maximum of 15% of their annual
compensation (subject to a maximum limit imposed by federal tax law). The
Company makes no matching contributions.

11. SUBSEQUENT EVENTS

On January 10, 2001, the Company announced it had acquired worldwide rights
to Amphotec-Registered Trademark- from ALZA Corporation. The transaction terms
include an upfront license fee of $9.0 million, milestone payments based upon
sales levels and the development of Amphotec-Registered Trademark- in
combination with ACTIMMUNE-Registered Trademark-, and royalties payable upon net
sales levels. Amphotec-Registered Trademark- is an FDA-approved lipid-complexed
form of amphotericin B indicated for the treatment of invasive aspergillosis, a
life-threatening fungal infection.

On March 26, 2001, the Company announced the formation of an international
strategic partnership with Boehringer Ingelheim International GmbH, to develop
and commercialize interferon gamma-1b under Boehringer Ingelheim's trade name,
Imukin-Registered Trademark-, in all countries outside of the United States,
Canada and Japan. Indications to be developed include idiopathic pulmonary
fibrosis (IPF), tuberculosis, systemic fungal infections, chronic granulomatous
disease (CGD) and osteopetrosis, as well as additional indications to be agreed
upon later. Under the agreement, InterMune will fund and manage clinical and
regulatory development of interferon gamma-1b for all disease indications. The
two companies will share in the profits from commercializing interferon gamma-1b
through a specified royalty schedule.
