INTRODUCTION

    GalaGen Inc. ("GalaGen" or the "Company") is developing oral therapeutics
to treat and prevent a broad range of human infectious diseases.  Using its
proprietary processes, the Company has produced polyclonal antibodies that
target specific pathogens infecting the human gastrointestinal ("GI") tract,
including bacteria and their toxins, parasites, fungi and viruses.  These
polyclonal antibodies are derived from bovine colostrum, the milk collected in
the first few milkings of a dairy cow after its calf is born.  When polyclonal
antibodies are administered orally to humans, they can provide passive immunity
within the GI tract.  The Company believes that its pharmaceutical products
could offer an attractive therapeutic alternative to traditional antibiotics at
a time when increasing antibiotic resistance and emerging new pathogens are
becoming more prevalent.*

    The Company believes that certain of its products in development face a
shorter and less expensive path to regulatory approval than many traditional
biopharmaceutical products.*  The Company's lead product in development,
SPORIDIN-G, addresses a critical need of seriously-ill immunocompromised
patients where no approved therapy exists for the infection.  The Company
believes this product may, therefore, qualify for expedited regulatory review.* 
Because the Company's products are derived from cows' milk, they do not
represent new chemical compounds with uncertain toxicity, but rather their
components are commonly found in dairy foods that are already widely consumed. 
Multiple products can be manufactured using a single, proprietary manufacturing
process and facility, and as a result the Company believes that additional
products will not require significant separate investments in manufacturing
facilities or process techniques.*


BACKGROUND

    Antibiotics and vaccines (active immunizations) are currently the most
common therapies for the treatment and prevention of infections.  Unfortunately,
both have significant limitations for the management of infections.  Pathogens
are increasingly resistant to antibiotics.  Overuse of antibiotics may result in
selection for additional resistant strains and, occasionally, results in the
onset of serious secondary infections.  Vaccines are not immediately effective
and usually require repeated vaccinations to raise the concentration of
antibodies in the

                                      2
<PAGE>

body to levels high enough to prevent or counteract disease. For many of the 
infectious diseases the Company is addressing, this delay may be 
unacceptable, because it may permit progression of the disease to severe or 
even fatal stages.  Active immunization of the GI tract is also difficult.  
To produce significant and effective antibodies in the GI tract, stimulation 
of healthy, functioning immune cells in the GI mucosal surfaces is necessary. 
These cells are significantly depleted or inactive in immunocompromised 
patients, thereby impairing the normal production of antibodies in this area. 
For these reasons, new therapeutic approaches for treating and preventing GI 
infections are needed. 

    One alternative to antibiotics and vaccines is passive immunity.  Passive
immunity consists of using antibodies produced by one individual or animal to
treat or prevent infection in another.  Such antibodies can be administered
systemically by injection for systemic infections or orally for GI infections.
Breast feeding is the most common example of passive immunity delivered to the
GI tract, with the mother providing natural protective antibodies to her infant
through her milk.  Similarly, dairy cows provide antibodies to calves through
the colostrum, which is the milk produced during the first several days of
lactation.  The concentration of antibodies in colostrum is many times higher
than the normal concentration in milk. 

    Advantages of passive immunity for treating or preventing GI tract
infections are numerous. Orally-delivered antibodies provide immediate treatment
of existing infections and provide for rapid temporary protection against
developing infection.  They may be delivered in high concentrations directly to
the site of infection in the GI tract rather than through the blood-stream. 
They are polyclonal, meaning that they bind to many different surface features
of a pathogen and are thus less likely to permit the development of resistant
pathogens.  They do not disrupt the GI tract's natural bacterial flora, which is
necessary for normal digestion and intestinal function.  As a result of these
advantages, passive immunity can be used for both acute treatment and long-term
prevention of disease. 

    An important potential application of passive immunity is the management of
infections in immunocompromised patients.  In these patients, the immune system
is impaired by diseases like AIDS or by treatments such as chemotherapy for
cancer and immunosuppressive drugs for organ transplantation and, consequently,
these patients are incapable of mounting an adequate immune response to
pathogens.  Repeated dosing of the mucosal surface with protective antibodies
from an external source can interrupt the infecting pathogen's life cycle or its
toxins and prevent the progression of the infection.  When bound by antibodies,
the unwanted pathogens can be eliminated from or degraded within the GI tract. 

THE COMPANY'S CORE TECHNOLOGY AND PRODUCT BENEFITS

    The Company's products contain antibodies derived from bovine colostrum. 
The products are orally administered to humans and provide passive immunity
within the GI tract.  Through their natural exposure to the environment, cows
have developed antibodies that recognize and bind to many human pathogens.  The
antibodies may block the pathogen's effect by immobilizing it, killing it,
promoting its ingestion and destruction by white blood cells, or preventing it
from attaching to and colonizing the GI tract.  In these ways, the antibodies
help to eliminate the pathogen from the infected individual.  The Company's
proprietary immunization technologies, through the use of immune system
stimulating adjuvants, increase by many fold a dairy cow's natural production of
pathogen-specific polyclonal antibodies in its colostrum.

    Standard dairy processing techniques destroy the activity of most of the
antibodies present in milk and colostrum.  The Company's proprietary process
used to concentrate antibodies has been developed through many years of research
and development.  This work resulted in a process that uses several well-tested
and efficient dairy manufacturing techniques that have been modified to preserve
the biological activity of the antibodies.  The Company manufactures its
products in accordance with pharmaceutical specifications for oral dosage
formulations.  The Company supports its proprietary antibody processing 
system with a quality control system 


                                      3
<PAGE>

that regulates, monitors and reviews the system in compliance with current 
Good Manufacturing Practices ("GMP") for the manufacture of biologics.

    The Company believes that its core technology will permit the continued
development of an expanded product portfolio targeting many GI pathogens, due to
several key attributes that include rapid product discovery, accelerated
clinical development, reduced development costs, and broad applicability for
multiple infectious diseases.*

BUSINESS STRATEGY

    The Company's objective is to develop and rapidly commercialize a new class
of safe and effective pharmaceutical products that use its proprietary
polyclonal antibody-based technology for treating and preventing infections.* 
The Company is pursuing this objective with the following strategies:

         TARGET LIFE-THREATENING DISEASES.  Initially, the Company is targeting
    life-threatening infections in immunocompromised patients, where the
    possibility of seeking expedited regulatory review may result in rapid
    progress to market.* 

         RETAIN MANUFACTURING CONTROL.  The Company intends to maintain control
    of its proprietary manufacturing processes by retaining all rights for the
    manufacture of bulk materials required for the commercialization of its
    products.  The Company has constructed a pilot GMP production facility that
    will support the commercial launch of its lead products in development and
    plans to seek a larger manufacturing facility to meet its longer-term
    production needs.*

         LEVERAGE PROPRIETARY TECHNOLOGY.  The Company intends to leverage its
    proprietary core technology to develop a portfolio of orally-delivered
    polyclonal antibody products that are all based on a similar manufacturing
    process.*  The Company intends to pursue new adjuvants for its immunization
    regimens and new antigens for additional products through internal and
    collaborative development, licensing of technology and acquisitions.*

PRODUCTS IN DEVELOPMENT

         The Company believes that its colostrum-derived polyclonal antibody
    products in development may provide many attractive clinical benefits and
    offer a safe and effective alternative to antibiotics and other
    therapeutics.*

         WELL-TOLERATED, DAIRY-DERIVED ANTIBODIES.  Orally-delivered,
    dairy-derived polyclonal antibodies have been administered in several
    studies by the Company and others to over 1,000 individuals with no serious
    adverse effects.  Antibodies are among the many milk proteins commonly
    consumed in everyday dairy products such as milk, yogurt and cheese. 
    Lactose levels in the Company's product candidates have been reduced to
    approximately one-tenth that of milk.  The Company believes that the
    product should, therefore, be tolerable by all but the most
    lactose-intolerant individuals.*

         RAPID ONSET OF ACTION AND A SUPPLEMENT TO ACTIVE IMMUNITY.  Polyclonal
    antibody products deliver high concentrations of pathogen-specific
    antibodies to the site of infection and have a rapid onset of action, while
    active immunizations, such as polio or hepatitis B vaccines, may take weeks
    or months to provide adequate immune protection.  Passive immune protection
    may be especially important where there is not time for active
    immunizations to be effective (for example, when there is exposure to
    infection or when an infection has become established and immediate therapy
    is needed) or where the underlying immune suppression leaves an individual
    incapable of responding to the active immunization (for example, in AIDS
    patients).

                                      4
<PAGE>


         AVOID PROBLEMS ASSOCIATED WITH ANTIBIOTIC USE.  Polyclonal antibodies
    recognize multiple binding sites on a target pathogen and have multiple
    potential mechanisms of action, including the neutralization of toxins. 
    With appropriate immunization regimens, polyclonal antibodies can be
    produced that recognize different strains of the same pathogen and affect
    even those strains that may be resistant to antibiotics.  In contrast,
    other classes of antiinfectives, including antibiotics and monoclonal
    antibodies, work by interrupting a single mechanism or by binding to a
    single site and are, therefore, more likely to be overcome by bacterial
    adaptation.  Unlike broad-spectrum antibiotics, orally-delivered polyclonal
    antibody products are selective for specific pathogens and do not disrupt
    the GI tract's normal bacterial flora.  Broad-spectrum antibiotics may
    disrupt the natural and beneficial GI bacterial flora and foster the
    subsequent overgrowth of certain disease-causing pathogens.  The
    selectivity of polyclonal antibodies should permit their use for prolonged
    periods to prevent infections, without promoting the development of
    resistant strains. 

         STABILITY AND EASE OF USE.  The Company's product candidates are
    stable powder concentrates with a shelf life exceeding two years.  These
    products can be formulated into a variety of delivery formats, including
    tablets, capsules, chewing gum and sterile liquids.  The standard dosage
    form is a dry powder which, when reconstituted, has the consistency and
    flavor of milk.

The Company currently has four products in development:

SPORIDIN-G

    The Company is developing SPORIDIN-G for the treatment of C.
PARVUM-associated diarrhea in immunocompromised patients.  The Company believes
that this product has the potential to improve diarrheal symptoms in AIDS
patients with C. PARVUM, thereby improving their quality of life as well as
significantly decreasing their annual health care costs.*  In March 1994, the
Company received notification from the U.S. Food and Drug Administration (the
"FDA") that SPORIDIN-G qualified for Orphan Drug designation for a

                                      5
<PAGE>

therapeutic indication.  There is currently no approved drug to treat this 
disabling infection.  Based upon a number of studies, including a marketing 
study commissioned by the Company and data from the Centers for Disease Control
(the "CDC"), the Company originally believed that C. PARVUM-associated diarrhea
affected approximately 8 to 10 percent of AIDS patients in the U.S. and Europe. 
As discussed  further below, the Company has been delayed in the patient
enrollment of its Phase II/III clinical study due to the approval in the second
quarter of 1996 of several new antiviral therapies used in the management of
AIDS patients.  Based upon these new antiviral therapies, the Company now
believes that the estimated rate of C. PARVUM infection of AIDS patients may be
lower than 8 to 10 percent.  However, it is not currently known what the 
long-term effects of these new antiviral therapies will be for an AIDS patient
and whether they may continue to affect the rate of C. PARVUM infection in AIDS
patients.

    The CDC reports that the number of persons living with AIDS in the United
States was approximately 202,000 as of the end of June 1996.  The Company
believes this figure underestimates the actual number of persons living with
AIDS due to under-reporting and under-diagnosis.  The Company also believes this
number is likely to increase in the future; however, the rate of increase is
difficult to predict due to the dynamic nature of the AIDS epidemic and the
uncertain impact of new antiviral therapies on extending survival of AIDS
patients.* 

    One hallmark of AIDS is the onset of multiple opportunistic infections. 
Cryptosporidiosis is an AIDS-defining opportunistic infection.  The parasite
C. PARVUM is a major cause of intractable diarrhea in AIDS patients that results
in profound weight loss, malnutrition, dehydration, and in some cases death.
Patients often require hospitalization for administration of intravenous fluids
and nutrition.  A retrospective study reported the incidence and cost of
C. PARVUM infection in AIDS patients exposed when the Milwaukee water supply was
contaminated by the parasite in 1993.  Cryptosporidiosis developed in 33 of the
73 patients studied.  The 33 infected patients had a higher death rate, spent
more days in the hospital (12.1 versus 1.1 days) and had much higher total
medical care charges, averaging $25,000 per patient, than the patients not
infected. 

    Unless a patient's immunologic defects are reversed, cryptosporidiosis
usually continues in a persistent or relapsing fashion for the duration of the
patient's life.  Other immunocompromised states in which cryptosporidiosis has
been diagnosed include measles, cancer therapy and immunosuppressive therapy,
used in treating patients with organ or bone marrow transplants, and congenital
hypogammaglobulinemia (a genetic condition in which antibody production is very
low). 

    Although more than 90 chemotherapeutic, biologic and anti-diarrheal agents
have been clinically tested against this disease, none has proven effective or
has been approved by the FDA for this indication.  Current therapy is primarily
supportive, involving a regimen of anti-diarrheal agents, nutritional
supplements and rehydration with intravenous fluids and electrolytes.  The
efficacy of several therapeutic agents continues to be explored in ongoing
clinical trials; however, published studies report only modest symptomatic
efficacy for these agents. 

    SPORIDIN-G has been studied in two clinical trials for the treatment of
C. PARVUM infections.  In a Phase I/II open-label clinical trial completed in
October 1995 involving 24 AIDS patients with chronic diarrhea, the product was
demonstrated to be safe with a statistically significant 49 percent reduction in
stool weight observed in the 12 C. PARVUM only-infected patients treated with an
oral formulation of Sporidin-G.  The product was well tolerated by most patients
with no serious adverse events.  Clinical results of this Phase I/II study were
published in the December 1996 issue of  THE JOURNAL OF ACQUIRED IMMUNE
DEFICIENCY SYNDROMES AND HUMAN RETROVIROLOGY.  In addition, 54 adult and
pediatric immunocompromised patients have been enrolled in an open-label,
uncontrolled compassionate use study.  Preliminary analysis of data received
from the first 34 patients treated showed that 20 patients appeared to gain
therapeutic benefit based on two or more of the following clinical parameters:
measure of diarrhea outcome (clinically significant reduction in stool frequency
and/or volume), clinical global assessment, weight gain and final medical
report.  There were no reports of serious adverse events related to treatment.

                                      6
<PAGE>

    A multi-center, double-blind, placebo-controlled, Phase II/III clinical
trial was initiated in January 1996 evaluating the efficacy and safety of
SPORIDIN-G in C. PARVUM-infected patients with AIDS and chronic diarrhea.  The
primary endpoint for this trial will be reduction in stool frequency.  The
Company recently implemented certain product improvements, including technology
licensed from Chiron Corporation ("Chiron"), which has significantly enhanced
the levels of C. PARVUM-specific antibodies in SPORIDIN-G. Preclinical studies
have demonstrated improved activity in several model systems.  This enhanced
product is being used in the Phase II/III trial.  The Company believes that the
higher antibody levels in this material may result in improved efficacy and may,
in the future, permit a reduction in dosage.*  If the Phase II/III trial
demonstrates efficacy, the Company believes that the data from the trial may
support the filing of a Product License Application ("PLA") for regulatory
approval of SPORIDIN-G by the FDA.*  This Phase II/III clinical trial was
originally scheduled for completion in the fourth quarter of 1996, but its onset
was delayed due to the approval in the second quarter of 1996 of several new
antiviral therapies used in the management of AIDS patients.  To compensate for
these unexpected developments, the Company increased the number of trial sites
and implemented additional aggressive recruiting efforts. The Company 
anticipates completing enrollment of the clinical trial by the end of the third
quarter of 1997.*

    In addition to treating C. PARVUM, the Company believes that SPORIDIN-G may
be useful for treating diarrhea in Human Immunodeficiency Virus ("HIV") positive
or AIDS patients where no specific pathogen is identified.*  Diarrhea in these
patients frequently does not respond to standard anti-diarrheal agents and is
thought to be caused, in part, by bacterial overgrowth of the small intestine. 
Based upon published anecdotal reports of reduced diarrheal output of AIDS 
patients treated with bovine based antibody products, the Company believes 
that SPORIDIN-G may be useful in reducing diarrheal symptoms in these 
patients.*

DIFFISTAT-G

    The Company is developing DIFFISTAT-G for the treatment and prevention of
antibiotic-associated diarrhea.  This complication of antibiotic therapy results
when the antibiotics eliminate the GI tract's normal bacterial flora and foster
the subsequent overgrowth of certain disease-causing bacteria, most often
C. DIFFICILE. Each year, it is estimated that more than 400,000 patients in
hospitals and long-term health care institutions in the U.S. contract
antibiotic-associated diarrhea due to C. DIFFICILE.  The severity of diarrhea
resulting from C. DIFFICILE may vary from a mild diarrhea to a life-threatening
condition.  Even the most mild cases in hospitals and long-term health care
institutions warrant treatment due to the contagious nature of the disease. 

    Currently, the first stage of treatment for antibiotic-associated diarrhea
involves the discontinuation of the causal antibiotic therapy, if possible, and
often the initiation of different antibiotics to treat the C. DIFFICILE
infection.  Discontinuation of the causal antibiotic may result in inadequate
treatment of the underlying infection. Often, the serious nature of the
underlying infection makes it impossible to discontinue the causal antibiotic.
Therefore, prophylaxis for high risk patients would be desirable if there were a
product available that avoided the problems presented by antibiotics. 

    Metronidazole is the antibiotic of choice to treat antibiotic-associated
diarrhea, with oral vancomycin as a second choice that is generally reserved for
more severe or relapsing diarrhea.  The initial response to these antibiotics
usually is rapid and satisfactory.  However, relapse can be a significant
problem occurring in 20 to 40 percent of patients.  These relapses can occur
multiple times and result in significant disability for the patient.  In
addition, the use of oral vancomycin for this indication is being discouraged to
reduce the likelihood that other serious pathogens will develop resistance to
vancomycin.  The Company believes that DIFFISTAT-G may prevent and treat
C. DIFFICILE-associated diarrhea without the complications associated with
antibiotic treatment.*

    An animal model study of DIFFISTAT-G demonstrating positive prophylactic
results was completed in 1991.  When the product was administered to animals
before the introduction of C. DIFFICILE organisms, the animals receiving
DIFFISTAT-G survived longer and had markedly less diarrhea than animals
receiving a placebo. Additional laboratory studies conducted at Boston
University have shown that the product effectively blocks the binding and action
of toxins produced by C. DIFFICILE.  Results of these preclinical efficacy
studies for Diffistat-G were published in the February 1996 issue of
ANTIMICROBIAL AGENTS AND CHEMOTHERAPY.  A Phase I study was completed in normal
volunteers at Boston University to assess the bioavailability of the product and
to guide the choice of appropriate dosage for a Phase I/II therapeutic trial. 
Results of the first Phase I bioavailability trial have been published in
ANTIMICROBIAL AGENTS AND CHEMOTHERAPY in February 1997.  An emergency use
compassionate release program was initiated at the request of the FDA, and the
initial pediatric patient treated under this program had clearing of symptoms
and the infection.

    A second Phase I bioavailability trial in ileostomy patients was initiated
in December 1996 at Beth Israel Hospital in Boston to further evaluate
appropriate dosing and formulation.  The Company is planning a Phase  II trial
in patients with antibiotic-associated diarrhea in the first half of 1997 to
assess safety, efficacy and formulation.*

CANDISTAT-G

    The Company is clinically developing an oral antibody product, CANDISTAT-G,
for the prevention/treatment of thrush, or infection of the throat and oral
cavity with the fungus species CANDIDA ("CANDIDA").  This infection occurs in
most immunocompromised patients (cancer, organ/bone marrow transplant and
HIV/AIDS) at some time during their illness, and tends to become more prevalent
as the underlying immune deficiency state progresses.  The Company estimates
that more than 120,000 patients in the U.S. with AIDS may be affected with this
condition annually.  Infection of the oral cavity produces clinical symptoms
such as burning, pain, redness and swelling that can lead to a decrease in
nutritional intake and increased wasting.  Infection of the esophagus is less
common than infection of the throat and oral cavity, but symptoms are usually
more severe, resulting in painful and difficult swallowing.  Esophageal
candidiasis tends to occur later in the disease process.  Invasive infection of
the bloodstream by CANDIDA sometimes may occur in severely immunocompromised
patients, particularly when AZT and gancyclovir produce drug-related suppression
of bone marrow in AIDS patients.  CANDIDA infections are a leading cause of
death in cancer and transplant patients, especially in patients whose white
blood cell counts are depressed.  These immunocompromised patients are more
susceptible to invasive blood-borne fungal infections than are AIDS patients,
and such infections carry a high risk of mortality.  Because of this risk,
antifungal agents are commonly administered prophylactically. 

    Short-term therapy with traditional antifungal agents, such as nystatin,
ketoconazole, or fluconazole, improves symptoms of thrush in immunocompromised
patients but often fails to clear the pathogen, resulting in a recurrence of
symptoms within weeks.  Prolonged therapy with these agents may produce clinical
benefits but also has been associated with increasing reports of drug-resistant
fungal strains.  Warnings by infectious disease experts for restraint in the use
of these antifungal agents, out of fear for increasing drug resistance,
highlight the need for alternative therapies.  The Company believes that a
polyclonal antibody-based product such as CANDISTAT-G may fulfill such a need,
particularly for the prevention of more severe thrush and blood-borne infections
originating from the GI tract.*

    CANDISTAT-G has been prepared by immunizing donor cows with several
different antigens thought to be important in the establishment of oral
infections with CANDIDA.  These preparations were shown to substantially inhibit
the binding of CANDIDA to human cheek cells in culture.  A pilot clinical
evaluation for up to 30 bone marrow transplant recipients and 15 
historically-matched controls in a European Phase I/II dose-ranging clinical 
trial at a major teaching hospital in Sweden commenced in January 1996.  This 
population has been selected for initial evaluation of safety and efficacy 
because a high percentage of patients develop thrush within a

                                      8
<PAGE>

defined time after receiving the transplant and they are at a very high risk 
of developing blood-borne infections. Information from this open-label study 
will be used to develop dosing regimens and treatment durations.  This trial 
is anticipated to be completed in the first half of 1997.*

PYLORIMUNE-G

    The Company is developing a polyclonal antibody product to treat gastritis
and ulcers caused by the bacterium H. PYLORI.  The prevalence of duodenal ulcers
in the United States is estimated at 3.5 million cases and each year there are
estimated to be at least 250,000 new cases.  Most of these are caused by
infection with H. PYLORI and persistent infections lead to a high relapse rate
after conventional ulcer treatment regimens (e.g., acid-suppressing agents). 
Since the discovery of the relationship between H. PYLORI infection and ulcers,
a major trend in the treatment has been the increased use of antibacterial
"triple therapy" (a combination of several antibiotics, bismuth, and inhibitors
of gastric acid production) instead of or in addition to conventional ulcer
therapies.  While most of these antibiotic-based regimens are partially
effective, compliance is difficult and 10 to 20 percent of patients fail therapy
in part because of antibiotic resistance.  Some experts believe the incidence of
antibiotic resistance is likely to increase over time, providing a strong
rationale for new therapeutic approaches. The Company believes that the limited
effectiveness of currently available therapies and growing antibiotic resistance
offer an opportunity for its polyclonal antibody product in development,
PYLORIMUNE-G.

    Initial laboratory studies with PYLORIMUNE-G have successfully demonstrated
neutralizing antibody activity against a key feature of H. PYLORI.  The Company
has access to five key antigens for producing antibodies to inhibit or eradicate
H. PYLORI.  The Company is developing cell culture systems and animal models for
screening the efficacy of these proprietary antibody preparations.  In 1995 the
Company entered into a strategic alliance with Chiron for the development of
colostrum-based polyclonal antibody products to treat H. PYLORI.  Chiron is
participating in the research and development program with its animal models.
Testing of antibodies will continue during 1997.*

OTHER MARKET OPPORTUNITIES; FOOD APPLICATIONS OF THE COMPANY'S TECHNOLOGY.

    In addition to therapeutic products targeted at GI diseases, the Company 
believes that its polyclonal antibody technology lends itself to the creation 
of food products or dietary supplements with health claims, often called 
"functional foods" or "nutraceuticals".* These have been defined as food 
which provide benefits beyond their nutritional value.  While there is not a 
regulatory definition for the terms "functional food" or "nutraceutical", the 
enactment by Congress of the Nutrition Labeling and Education Act (NLEA) in 
1990 and the Dietary Supplement Health and Education Act (DSHEA) in 1994 
enabled the regulatory process for marketing foods or dietary supplements 
bearing such claims.  The Company believes that the incorporation of its 
polyclonal antibody technology in foods or dietary supplements would add 
benefits to these products, either by modifying the risks associated with GI 
pathogens or by helping to normalize GI function, especially after illness or 
surgery.*

    When the Company was formed, Land O'Lakes, Inc. ("Land O'Lakes") retained 
certain rights to food applications for the Company's polyclonal antibody 
technology.  Any development of such food applications by GalaGen would 
require Land O'Lakes consent.  In connection with the Company's agreement 
with Chiron, Land O'Lakes consented to the Company's use of polyclonal 
antibody technology for food applications of an H. PYLORI product.  The 
Company is continuing efforts to expand applications of its technology to 
food products, including in conjunction with potential partners, and will 
seek Land O'Lakes consent in specific cases as they arise.  In March 1997, 
the Company obtained Land O' Lakes' consent to GalaGen's development of a 
certain functional food. No assurance can be given that Land O'Lakes will 
give its consent in any particular case.

                                      9

MANUFACTURING SYSTEM

    The Company's manufacturing system utilizes the existing milk production
infrastructure.  The Company's system has been designed to access very large
numbers of cows in commercial milking herds, organize them into discrete
product-specific groups, immunize them with specific antigens to heighten the
natural production of pathogen-specific antibodies in their colostrum, collect
the colostrum and concentrate the antibodies using a proprietary process.  This
process preserves the essential antibody activity while reducing unnecessary
components, including microbial contaminants. 

    Modern dairy cows, having been bred for high volume milk production,
produce colostrum in quantities far greater than their calves can consume.  This
surplus colostrum is not placed into the commercial milk supply and is
ordinarily a waste product.  The Company's technology turns the surplus
colostrum into a valuable raw material.  With the Company's manufacturing
system, the Company believes that polyclonal antibodies can be produced from
colostrum at a fraction of the cost of either human serum-derived polyclonal
antibodies or cell culture-derived monoclonal antibodies.  The high cost of 
producing monoclonal antibodies, in particular, makes their administration by 
the oral route prohibitively costly.  

    Because a cow only produces colostrum for several days per year, many cows
will be needed to supply raw materials for each product. The Company has
agreements with Land O'Lakes which provide the Company with access to the
colostrum from approximately 250,000 cows through the Land O'Lakes cooperative
system. The Company believes that Land O'Lakes' recent entry into the California
dairy system could increase the number of cows available to the Company.* 

    The Company's processing system is the same for the manufacture of all of
the Company's polyclonal antibody products.  The colostrum for each potential
product is processed to a bulk powder using the same procedures, according to
the same specifications, and on the same equipment.  This bulk powder may
undergo final finishing steps, depending on the dosage form that is desired. 
The primary point of product differentiation is the antigen/adjuvant combination
(immunogen) used to produce the specific and desired antibody response in the
cow.  This antibody specificity is used to define a product targeting a specific
disease and indication. 

    Standard dairy processing techniques destroy the activity of most of the
antibodies present in milk and colostrum and render them inactive.  The
proprietary process used by the Company to concentrate antibodies has been
developed by the Company through many years of research and development.  This
work has resulted in a process that uses well-tested and efficient dairy
manufacturing techniques that have been modified to preserve the biological
activity of the antibodies.  The process reduces the bioburden to levels
significantly lower than those present in milk or milk products, and in
accordance with pharmaceutical specifications for oral dosage formulations.  The
Company is supporting its proprietary antibody processing system with a quality
control system designed to regulate, monitor and review the system in compliance
with GMP for the manufacture of biologics. 

    Construction of the Company's GMP pilot plant facility within the existing
Land O'Lakes pilot plant complex in Arden Hills, Minnesota was  completed at the
end of 1996, and will be fully validated and operational in the second quarter
of 1997.*  The Company believes that the new pilot plant facility will meet the
commercial sales requirements of SPORIDIN-G.* Land O'Lakes has guaranteed the
equipment leases associated with the new pilot plant facility.  The Company is
in the process of identifying contract manufacturers with equipment and GMP
procedures which are appropriate for manufacture of the Company's potential
products.  The Company believes that use of such contract manufacturers would
enable it to increase its production capacity quickly, if required, in less time
and cost than constructing its own facility.*

LICENSE AGREEMENTS AND RESEARCH COLLABORATIONS

                                      10
<PAGE>

    The Company's research and development strategy is to pursue its own
research programs internally and to complement such programs by establishing
relationships with key external medical, academic, governmental and major
pharmaceutical research organizations.  Specifically, the Company intends to
continue complementing its extensive current technology base by acquiring access
to additional proprietary technology and patents in the areas of vaccine,
molecular biology, and processing and manufacturing technology.*  The Company
also may seek collaborative arrangements for commercialization of its polyclonal
antibody products.* 

    The Company's polyclonal antibody technology may be applied to the
development of biopharmaceutical products in many areas.*  To exploit its core
technology as broadly as possible in human biopharmaceutical applications, the
Company's strategy is to enter into licensing and collaborative relationships
with pharmaceutical companies with complementary product lines.  The Company
spent $5.3 million, $3.7 million and $3.4 million for research and development
in fiscal years 1996, 1995 and 1994, respectively.  

LAND O'LAKES RELATIONSHIP

    The Company believes that the Company's existing relationship with Land
O'Lakes provides it with certain advantages over existing and potential
competitors.  Land O'Lakes made significant advances in the development and
commercialization of polyclonal antibody products for treating and preventing
diseases in animals.  This technology provides the Company with a solid
foundation on which to base its efforts to develop similar products for the
treatment and prevention of GI diseases in humans. 

    Under a supply agreement with Land O'Lakes, the Company agreed to purchase
all of its commercial requirements for colostrum from Land O'Lakes through
May 7, 2002, subject to Land O'Lakes' option to renew the supply agreement for
an additional ten-year period.  The Company must provide program specifications
to Land O'Lakes prior to commencing each of its commercial programs and Land
O'Lakes must notify the Company within a specified period whether it will supply
according to the agreement.  If Land O'Lakes does not confirm during that period
that it will supply colostrum according to the specifications, then the Company
has the right to obtain the colostrum from alternative sources.  Commercial
production could be delayed if Land O'Lakes does not supply according to the
supply agreement and the Company is required to locate an alternate supplier.

    When the Company was formed, it signed a letter of intent with Land O'Lakes
to develop strategic relationships focused on the development of functional food
products.  In the original license agreement with Land O'Lakes, the Company
retained rights to pursue the development of infant formula products containing
polyclonal antibody technology.  As mentioned above, Land O'Lakes consented to
the Company's use of polyclonal antibody technology for food applications of an
H. PYLORI product. The Company is continuing efforts to expand applications of
its technology to food products, including in conjunction with potential
partners, and will seek Land O'Lakes consent in specific cases as they arise.*
No assurance can be given that Land O'Lakes will give its consent in any
particular case.

CHIRON RELATIONSHIP

    In March 1995, the Company and Chiron entered into a License and
Collaboration Agreement involving the licensing of Chiron adjuvant technology to
the Company for the development of polyclonal antibody products processed from
bovine colostrum and the cross-licensing of Chiron proprietary H.
PYLORI-associated technology and Company proprietary H. PYLORI antigens for a
collaboration to research and develop passive immune therapies, using bovine
antibodies, against H. PYLORI.

                                      11
<PAGE>

    Under the agreement, Chiron granted the Company an exclusive worldwide
license for the use of a proprietary Chiron adjuvant for the production of
SPORIDIN-G and PYLORIMUNE-G. See "Products in Development - SPORIDIN-G" and
"-PYLORIMUNE-G" above.  Use of the adjuvant for providing additional polyclonal
antibody products processed from bovine colostrum can be designated under the
terms of the agreement.   Except as described below with regard to PYLORIMUNE-G,
the Company's license to the Chiron adjuvant technology expires on the later of
the expiration date of the last to expire of the licensed patents covering the
technology or, within a given country, 10 years after the first commercial sale
of a product making use of the licensed technology within such country.

    In addition, under the agreement Chiron and the Company are to collaborate
on the development of polyclonal antibody products processed from bovine
colostrum targeting infections caused by H. PYLORI, the bacterium associated
with ulcers and gastritis.  The research program will focus on producing
specific, high potency antibodies directed against several products of H. PYLORI
that the bacterium uses to attach to the stomach surfaces, and neutralize
gastric acidity that would otherwise kill the bacterium, and inflame the gastric
and duodenal surfaces.  Chiron has an option for exclusive worldwide marketing
rights for any H. PYLORI product resulting from the collaboration with profits
being shared between Chiron and the Company according to a preset formula.  In
connection with the agreement, Land O'Lakes consented to the Company's use of
polyclonal antibody technology for food applications of an H. PYLORI product. 
The Company's license to the Chiron adjuvant technology for use in PYLORIMUNE-G
is subject to early termination by Chiron if (i) no PLA has been filed for
PYLORIMUNE-G by March 1, 2001, (ii) certain competitors of Chiron acquire
control of the Company or, (iii) by the time of the first demonstration of
efficacy of PYLORIMUNE-G, Chiron has not received an opinion of independent
counsel selected by Chiron that the manufacture, use or sale of PYLORIMUNE-G
does not infringe third party patents.

PROPRIETARY RIGHTS AND PATENTS

    The Company's policy is to protect its proprietary technology as trade
secrets and by filing patent applications on technology for which the Company
believes patent protection is available and is in the best interest of the
Company.  The Company also relies upon know-how, continuing technological
innovations and licensing opportunities to develop and maintain its competitive
position. 

    The Company believes that certain of its process improvements are more
valuable as trade secrets than as patented processes, where the process
improvements would have to be publicly disclosed.  The Company relies on trade
secrets and proprietary know-how it developed while manufacturing polyclonal
antibody products for veterinary use.  The Company believes that substantial
barriers exist for competitors desiring to commercialize polyclonal antibody
products derived from milk or colostrum*; however, there can be no assurance
that other companies will not develop production processes or initiate
relationships with other large dairy cooperatives to develop a similar
procurement system.  The Company seeks to protect trade secrets and know-how
through confidentiality agreements with employees, consultants and other
parties.  These agreements provide that all confidential information developed
or made known during the course of the relationship with the Company is to be
kept confidential and not disclosed to third parties, except in specific
circumstances.  No assurance can be given that such agreements will provide
meaningful protection for the Company's unpatented trade secrets or provide
adequate remedies in the event of unauthorized use of such information.  Neither
can assurance be given that others will not independently develop substantially
equivalent proprietary information and technology or otherwise gain access to
the Company's trade secrets or disclose such technology. 

    The Company has four patent applications pending and has acquired licenses
to a number of patents or patent applications of others.  The Company's four
patent applications are in the area of polyclonal antibody products for humans. 
The Company believes that useful, new and unobvious antibody formulations may be
patentable.*  Furthermore, in some cases, patent coverage may be available for
the vaccines or antigens used to provoke the immunological response which
produces the antibodies.  The Company's strategy is to pursue patent

                                      12
<PAGE>

protection for each of its products where possible, including their 
components (e.g., antigens, vaccine compositions), as well as for certain 
process and formulation improvements, although the Company may not be 
successful in achieving broad patent protection for its technology.

    The Company has become aware of several patents that may relate to its
polyclonal antibody technology. In 1991, the Company became aware of one such
issued patent.  Land O'Lakes engaged outside patent counsel to review the patent
and such counsel rendered its written opinion to Land O'Lakes that the patent is
not infringed by the Company's technology.  The Company engaged its own outside
patent counsel to review the patent and such counsel rendered its independent
opinion that the patent is not infringed by the Company's technology and that,
in any event, the patent would be invalid if it were interpreted broadly enough
so as to cover the Company's technology.  While the Company does not regard the
patent as a threat to its business*, there can be no assurance that the holder
of the patent will not pursue litigation which could be costly to the Company. 
In 1993, the Company became aware of another issued patent relating to the
application of colostrum-based passive immunity technology to an H.
PYLORI-specific product.  The Company engaged outside patent counsel to review
the patent, and a related patent which was subsequently issued, and such counsel
rendered its independent opinion to the Company that neither patent is valid
and, in any event, it is not certain at this time if the Company's technology
would infringe either patent even if valid.  While the Company does not regard
the patents as a threat to its business*, there can be no assurance that the
holder of the patents will not pursue litigation which could be costly to the
Company.  The Company recently became aware of a published international patent
application entitled "Urease-Based Vaccine and Treatment of Helicobacter
Infection".  To date, no patent on this application has been granted and
therefore the Company cannot meaningfully assess the impact, if any, of this
patent application on its business. 

GOVERNMENT REGULATION

    The Company's current products are classified as human biological drugs and
their research, development and marketing are subject to substantial regulation
by the FDA as well as state and local entities.  The Federal Food, Drug and
Cosmetic Act, the Public Health Service Act and other federal statutes govern
the testing, manufacture, safety, effectiveness, approval, storage,
recordkeeping, labeling, advertising and promotion of the Company's products. 
Noncompliance with applicable statutory and regulatory requirements may result
in fines, recall or seizure of products, refusal to permit the Company to enter
into government supply contracts, refusal to approve PLAs, suspension or
revocation of product licenses and establishment licenses previously granted,
criminal prosecution, and debarment. 

    The process required by the FDA before the Company's products may be
marketed in the United States generally involves the following: (1) preclinical
laboratory and animal testing; (2) the submission to the FDA of an application
for Investigational New Drug application ("IND") approval to conduct human
clinical trials; (3) adequate and well-controlled human clinical trials to
establish the safety and efficacy of the biologic; (4) the submission of a PLA
for approval of a biologic; and (5) FDA approval of and issuance of a license
pertaining to a PLA prior to any commercial sale or shipment of the drug or
biologic.  In addition, drug manufacturing establishments must be registered
with and approved by the FDA.  Manufacturers of biologics must currently also
submit and obtain approval of an Establishment License Application ("ELA") prior
to commercial distribution of an approved biologic.  Manufacturing
establishments are subject to regular inspections by the FDA.  All manufacturing
facilities, production, testing and packaging operations and recordkeeping
practices must substantially conform to, among other requirements, FDA GMP
regulations. 

PRECLINICAL STUDIES

    Preclinical studies are conducted in the laboratory and in animal models to
gain preliminary information on biochemical and pharmacological properties of
the investigational drug or biologic and to identify any significant safety
problems.  The results of these studies are submitted to the FDA as part of the
IND

                                      13
<PAGE>

application.  Testing of previously unapproved new drugs and biologics in
humans may not commence until the IND becomes effective. 

IND APPLICATION

    The IND application notifies the FDA of the sponsor's investigational plan
for the drug or biologic and provides brief descriptions of the chemical
structure of the compound, the known pharmacological and toxicological effects
of the compound, and known information relating to the compound's safety and
effectiveness in humans, including possible risks and anticipated side effects. 
The IND authorizes a sponsor to conduct human clinical studies in order to
demonstrate relative safety and efficacy of the product in support of an
ELA/PLA.  Any time prior to or following the commencement of clinical trials
under an IND, the FDA may determine that human subjects are or would be exposed
to an unreasonable and significant risk of injury by participating in the trial
and may delay initiation of or suspend an ongoing trial. 

CLINICAL STUDIES

    Human clinical studies are typically conducted in three phases, which may
overlap, and are designed to collect additional data relating to the safety,
dosing and side effects of the proposed product and to the product's efficacy in
comparison with placebos or any currently accepted therapy.  Phase I clinical
studies are generally performed in 10 to 30 healthy human subjects or, more
rarely, selected patients with a targeted disease or disorder.  The goal is to
establish an initial data base about tolerance, safety and dosing of the product
in humans.  Phase II clinical studies are generally performed in small numbers
of carefully selected patients, usually 50 to 200.  Phase II studies are used to
obtain definitive statistical evidence of the efficacy and safety of the product
and dosing regimen.  Phase III consists of expanded large-scale studies of
patients (200 to 2,000 patients or more) with the target disease or disorder, to
obtain statistical evidence of the efficacy and safety of the proposed product
and dosing regimen in a broader patient population.  These studies may include
investigation of the effects in subpopulations of patients, such as the elderly,
women or certain racial groups. 

    When patients are studied, Phase I and II studies may be combined. 
Phase I/II clinical studies are designed to establish initial data regarding the
tolerance, safety and dosing of the investigational drug or biologic, and to
obtain preliminary efficacy data in patients with the specific disease.  The
combination of different phases encourages the use of larger sample sizes and
may result in more reliable statistical results in the earlier phases. 
Subsequent to the Phase I and II studies, pivotal studies are carried out with
larger numbers of patients with the target disease or disorder.  These pivotal
studies may be either Phase II or Phase III.  Additional clinical trials beyond
the pivotal studies are sometimes required for licensing. 

    For several reasons, including the fact that its products address critical
needs of seriously-ill patient populations that are inadequately treated by
existing technologies, the Company is hopeful that it can obtain expedited
regulatory review for one or more of its products.  Such expedited review might
take the form of a waiver of, or only limited, Phase III studies.*  No assurance
can be given, however, that the FDA will agree to any such expedited treatment
with respect to any of the Company's products. 

PRODUCT LICENSING APPLICATION (PLA)

    Upon successful completion of clinical testing, the Company will file a PLA
and ELA with the FDA.*  The regulatory environment is evolving rapidly and is
being closely monitored.  The Company will pursue aggressively the possibility
of a streamlined, single filing, if the current procedure is modified by the 
FDA.*  These applications include, among other things, details of the 
manufacturing and testing processes and results of preclinical studies and 
clinical trials which, taken together, demonstrate that the drug or biologic 
is safe, pure, potent and effective.  FDA approval of the applications is 
required before the new product may be marketed.  There can be no assurance 
that the FDA will act favorably or quickly in reviewing submitted 
applications, and

                                      14
<PAGE>

significant difficulties or costs may be encountered by the Company in its 
efforts to obtain FDA approvals for its novel biological products.  The FDA 
may grant marketing approval, require additional testing or information or 
deny the applications.  The clinical studies may take three to five years or 
more to complete and there are no assurances that the clinical data obtained 
will demonstrate to the FDA that the product is safe and effective.  The FDA 
may require the Company to perform additional human testing.  There can be no 
assurance that the FDA will ever accept the Company's data as being 
sufficient to demonstrate the product's safety, purity, potency, or efficacy. 

    FDA policies currently require that the Company's manufacturing facility or
the manufacturing facility of a contract manufacturer be operational and in full
compliance with GMP standards prior to completing pivotal or Phase III clinical
trials.  If the Company or its designated contract manufacturer is unable to
make its facility operational before completing pivotal or Phase III clinical
trials on a product, the Company may have to perform additional clinical testing
with the product produced at the new facility. 

    The Company's clinical trials are at an early stage, and the Company has
not received approval from the FDA or any other government agency for the
manufacturing or marketing of any of its products.  Consequently, the
commencement of manufacturing and marketing of its products is, in all
likelihood, at least one to three years away, even for products which may gain
expedited review.*  Moreover, even after FDA approval of a PLA has been
obtained, further studies will likely be required to provide additional data on
safety or to gain approval for the use of a product as a treatment in clinical
indications other than those for which the product was initially tested.  The
FDA may also require post-marketing testing and surveillance programs to monitor
the product's effects.  Significant side effects may prevent or limit the
further marketing of the product, or move the FDA to withdraw its approval to
market the product, either temporarily, for example, by ordering a product
recall, or permanently, by withdrawing the New Drug Application ("NDA") or PLA
approval.  Continued compliance with all FDA requirements and the conditions in
an approved application, including product specification, manufacturing process,
labeling and promotional materials and record keeping and reporting
requirements, is necessary for all products. 

ORPHAN DRUG DESIGNATION

    The Company may seek an Orphan Drug designation and exclusive approval for
certain indications of its products.*  Pursuant to the Orphan Drug Act, the FDA
may grant Orphan Drug designation to a product or products intended to treat a
"rare disease or condition", defined as a disease or condition which affects
fewer than 200,000 people in the United States, or which affects more than
200,000 people, for which the cost of developing and making available the drug
will not be recoverable from sales of the drug in the United States.  Orphan
Drug designation may provide certain incentives to undertake the development and
marketing of the product.  In addition, following approval of the NDA or PLA for
an orphan-designated product, the FDA may grant exclusive marketing rights in
the United States for the designated and approved indication for seven years
following marketing approval and federal income tax credits for certain clinical
trial expenses.  There may be multiple designations of Orphan Drug status to the
same or different sponsors for a given drug or biologic intended for different
indications.  Only the sponsor for the first approved NDA or PLA for a given
drug or biologic for use in treating a given rare disease, however, may receive
marketing exclusivity.  The seven-year period of exclusivity applies only to the
particular product for the rare disease or condition for which the FDA has
designated the product an Orphan Drug.  Therefore, another manufacturer could
obtain approval of the same drug or biologic for a different indication or a
different drug or biologic for the orphan indication.  In addition, another
manufacturer could obtain Orphan Drug designation for an indication and product
for which the Company might otherwise attempt to obtain such a designation. 

    Because of recent efforts by the U.S. Congress to amend the exclusivity
provisions of the Orphan Drug Act, there is no assurance as to the precise scope
of protection that may be afforded by Orphan Drug designation

                                      15
<PAGE>

in the future or that the current level of exclusivity will be maintained.  
The tax credits provided for under the Orphan Drug Act expire on May 31, 
1997.  There can be no assurance that these tax benefits will be renewed. 

OTHER REGULATORY REQUIREMENTS

    The Company is also subject to regulation by the Occupational Safety and
Health Administration, the Environmental Protection Agency and the Minnesota
Environmental Quality Board and to regulation under the Toxic Substances Control
Act, the Resource Conservation and Recovery Act, among others, and other
regulations, and may in the future be subject to other federal, state and local
statutes or regulations.  The Company is unable to predict whether any agency
will adopt any regulation which would have a material adverse effect on the
Company.

    Sales of biologics outside the United States are subject to foreign
regulatory requirements that may vary widely from country to country.  Whether
or not FDA approval has been obtained, approval of a product by comparable
regulatory authorities of foreign countries must be obtained prior to the
commencement of marketing the products in those countries.  The time required to
obtain such approval may be longer or shorter than that required for FDA
approval. 

COMPETITION

    The human pharmaceutical and biotechnology industries are subject to
intense competition as well as rapid and significant technological change. 
While several of the Company's products target diseases for which there are
presently no effective therapies, the Company nevertheless is aware of companies
which are developing products that will compete for the same disease markets. 
The Company expects that the pharmaceutical and biotechnology industries will
continue to experience rapid technological development which may render the
Company's processes and products non-competitive or obsolete. 

    The Company is aware of direct competition from companies with products
designed to use immune mechanisms to treat infections and also potential
competition from companies developing new antibiotics and other anti-infective
substances.  At least two companies, Biomune Systems, Inc. and ImmuCell Corp.,
are developing colostrum-derived or milk-derived antibody products for treating
cryptosporidiosis; others are developing vaccines designed to elicit active
immune defenses against H. PYLORI or C. DIFFICILE.  Numerous pharmaceutical,
biotechnology and chemical companies, academic institutions, governmental
agencies and other public and private research organizations are conducting
research and development in the area of infectious diseases, including research
and development of new antibiotic products which will address the same diseases
the Company has targeted.  Many of these competitors, either alone or through
collaborative arrangements with large pharmaceutical companies or academic
institutions, have significantly greater financial, human and other resources
and greater expertise in research and development, testing, manufacturing,
marketing and distribution than the Company.  Consequently, these competitors
may succeed in developing, obtaining patent protection for, or commercializing
technologies and products that are more effective, easier to use or less
expensive than those the Company is developing.  In addition, early entry into
the market may have important advantages in gaining product acceptance and
market share.  Many of the Company's competitors, particularly large
pharmaceutical companies, have significantly greater experience than the Company
in conducting clinical trials and in obtaining FDA and other regulatory
approvals of products.  As a result, these competitors may succeed in obtaining
regulatory approval earlier than the Company for products with similar
indications.  Moreover, if the Company is successful in commercializing its
products, it will be required to compete with respect to manufacturing
efficiency and marketing capabilities, areas in which it has no experience. 

    The Company has assessed the factors that may make it competitive in this
environment and believes that its central strengths are its proprietary dairy
procurement and production processes, as well as its relationship with Land
O'Lakes to provide the raw materials for manufacturing products on a large
commercial

                                      16
<PAGE>

scale.  While there can be no assurance that other biopharmaceutical
companies will not initiate relationships with other large dairy cooperatives to
develop a similar procurement and production process, the Company believes that
the resources required to duplicate a system of similar scale in time, dollars
and expertise are substantial. 

EMPLOYEES

    At December 31, 1996, the Company had 30 employees, 6 of whom have Ph.D.
degrees, one who has a Pharm.D. degree and two of who have M.D. degrees (one of
which also has a Ph.D. degree).  Eight employees are currently working in
research and development and four employees are working in the clinical
regulatory area.  The Company believes its employee relationships are good. 

RISK FACTORS

    Certain statements made in this Annual Report on Form 10-K, including those
indicated by an asterisk above (some of which are summarized below), are
forward-looking statements that involve risks and uncertainties, and actual
results may differ.  Factors that could cause actual results to differ include
those identified below.

    GOALS OF COMPLETING ENROLLMENT IN THE PHASE II/III SPORIDIN-G BY THE END OF
THE THIRD QUARTER OF 1997, COMMENCING THE PHASE II DIFFISTAT-G TRIAL IN THE 
FIRST HALF OF 1997 AND COMPLETING THE PHASE I/II CANDISTAT-G TRIAL IN THE FIRST 
HALF OF 1997. The Company's products in development will require additional 
research and development and extensive clinical testing and regulatory approval 
prior to any commercial sales. There can be no assurance that clinical testing 
of any of the Company's products will be completed successfully within any 
specified time period, if at all. Time required for completion of trials may be 
affected by the rate at which patients meeting trial criteria can be found and 
enrolled. As noted above, the Company has been delayed in the patient enrollment
of its Phase II/III SPORIDIN-G clinical trial due to the approval in the second 
quarter of 1996 of several new antiviral therapies used in the management of 
AIDS patients and the impact of such therapies on the numbers of AIDS patients 
with C. PARVUM infection.  Moreover, the Company or the FDA may suspend clinical
trials at any time if the subjects or patients participating in such trials are 
thought to be exposed to unacceptable health risks. Although the Company 
believes that its products are safe, there can be no assurance that the Company
will not encounter problems in clinical trials which will cause the Company or 
the FDA to suspend clinical trials or which will result in delays in the 
Company's clinical trials.  The Company's human clinical trials were preceded 
by preclinical testing in animals, and the Company is continuing to conduct 
additional animal studies as part of its development program. Such testing may 
not be predictive of the results seen in humans.  

    DATA FROM THE PHASE II/III SPORIDIN-G TRIAL WILL SUPPORT APPLICATIONS FOR
REGULATORY APPROVAL.  The Company's products will be subject to extensive
regulation by federal, state and local governmental authorities in the United
States and any other countries where the Company's products may be tested or
marketed. The FDA and comparable agencies in other countries impose substantial
requirements that must be satisfied before newly developed products may be sold.
Approval by the FDA requires lengthy, detailed and costly laboratory and
clinical testing procedures to demonstrate a product's efficacy and safety
before the product can be sold. The Company anticipates that several of its
products, including SPORIDIN-G, may be eligible to obtain early FDA approval
because they may qualify for expedited review or may require less than the full
three phases of clinical testing.  However, the failure of the Company's
products to demonstrate safety or efficacy in early stages of clinical testing,
changes in government regulations or the inability of the FDA to complete the
necessary reviews within the time frames that the regulations currently provide
could prevent the Company from securing such early sale or early approval.
Moreover, there can be no assurance that the Company will ever receive FDA
approval for any of its products or, even if it does receive FDA approval for a
particular product, that the

                                      17
<PAGE>

Company will ever recover its costs in connection with obtaining such 
approval.  With respect to any of the Company's products, the failure of the 
Company to receive requisite FDA approval, or significant delays in obtaining 
such approval, could prevent the commercial development of such product and 
could have a material adverse effect on the Company.


    SHORTER AND LESS EXPENSIVE DEVELOPMENT PATH FOR GALAGEN PRODUCTS.  The
Company believes that certain of its products in development face a shorter and
less expensive path to regulatory approval than many other biopharmaceutical
products.  Factors that the Company believes may result in a shorter and less
expensive path include the favorable safety profile of the Company's products,
the fact that some of the Company's products address critical needs of patients
who are inadequately treated by existing technologies and that multiple products
can be manufactured by the Company using a single, proprietary manufacturing
process and facility, and as a result will not require separate investments in
manufacturing facilities or process techniques.  However, GalaGen is still at an
early stage of product development.  The Company does not have the approval of
the FDA for the sale of any products, nor is the Company aware of any other
FDA-approved biologic based on bovine colostrum-derived polyclonal antibody
technology for the human health care market. The Company's products will require
significant laboratory and clinical testing, additional development and
investment prior to commercialization. There can be no assurance that any of the
Company's product development efforts will be successful or that any candidate
products will prove to be safe and effective in clinical trials and receive
necessary regulatory approvals. Even if the Company is able to develop products
that receive required regulatory approvals, there can be no assurance that any
such products will achieve market acceptance and be commercially successful. 

    PILOT PLANT SHOULD PROVIDE CAPACITY FOR ANTICIPATED COMMERCIAL PRODUCTION
OF SPORIDIN-G.  The Company believes that its new pilot plant will meet the
anticipated requirements for commercial sales of SPORIDIN-G. To date, GalaGen
has manufactured SPORIDIN-G only in limited quantities in the existing Land
O'Lakes pilot plant.  To successfully establish commercial manufacturing
capacity, the Company will have to scale up its manufacturing processes and
demonstrate the ability to consistently manufacture a clinically safe product.
Given the limited manufacturing experience of the Company, no assurance can be
given that the Company will be successful in producing acceptable product on a
commercial scale and at acceptable costs in the new facility. The Company's
products will be regulated by the FDA as human biologics and its manufacturing
facility will have to be operational prior to completing its pivotal clinical
trials.  

    SPORIDIN-G HAS POTENTIAL TO IMPROVE QUALITY OF LIFE OF AIDS PATIENTS WITH
C. PARVUM AS WELL AS SIGNIFICANTLY DECREASE THEIR ANNUAL HEALTH CARE COSTS.  The
potential of SPORIDIN-G to improve the quality of life and decrease health care
costs of AIDS patients will depend, among other things, upon the ability of the
Company to obtain regulatory approval for SPORIDIN-G and to manufacture and
distribute SPORIDIN-G at a competitive price and upon the introduction of
competitive products.  No assurance can be given as to the ability of the
Company to obtain such approval or manufacture and distribute in such a manner
or that competitive products will not be introduced.

    ABILITY OF THE COMPANY TO SATISFY ITS ANTICIPATED CASH REQUIREMENTS THROUGH
APPROXIMATELY THE FIRST QUARTER OF 1998.  The Company's working capital and
capital requirements will depend upon numerous factors, including the progress
of the Company's clinical trials and research and development programs and the
timing and cost of obtaining regulatory approvals.  The Company's capital
requirements also will depend on the levels of resources devoted to the
development of manufacturing and marketing capabilities, technological advances,
the status of competitive products and the ability of the Company to establish
strategic alliances to provide research and development funding to the Company. 
The Company's ability to continue funding its planned operations beyond the
first quarter of 1998 is dependent upon its ability to obtain additional funds
through equity or debt financing, strategic alliances, license agreements or
from other financing sources.  A lack of adequate funding could eventually
result in the insolvency or bankruptcy of the Company.  At a minimum, if
adequate funds are

                                      18
<PAGE>

not available, the Company may be required to delay or to
eliminate expenditures for certain of its product development efforts or to
license to third parties the rights to commercialize products or technologies
that the Company would otherwise seek to develop itself.  Because of the
Company's significant long-term capital requirements, it may seek to raise funds
when conditions are favorable, even if it does not have an immediate need for
such additional capital at such time.  If the Company has not raised funds prior
to such time as the Company's needs for funding become immediate, the Company
may be forced to raise funds when conditions are unfavorable which could result
in dilution of the Company's current stockholders.

    COMMERCIALIZATION OF FUNCTIONAL FOOD PRODUCTS. Although at its inception
GalaGen entered into a letter of intent with Land O'Lakes to enter into
discussions regarding a strategic alliance for the commercialization of function
food products, no such discussions are currently underway.  Under a license
agreement with Land O'Lakes, GalaGen agreed not to compete for 15 years in the
area of functional foods based on polyclonal antibody technology.  Accordingly,
the development of functional food opportunities by GalaGen would require the
consent of Land O'Lakes.  No assurance can be given that such consent would be
given by Land O'Lakes in a particular case.  Land O'Lakes also has the right
under the license agreement to sublicense the polyclonal antibody technology
developed or acquired by the Company.  If Land O'Lakes refuses to waive its
right to such sublicenses, the Company's ability to acquire licenses to
polyclonal antibody technologies from others, for functional food opportunities
or otherwise, may be significantly impaired.

ITEM 2.  PROPERTIES

    The Company leases approximately 5,000 square feet of administrative and
laboratory space at the Land O'Lakes corporate office located in Arden Hills,
Minnesota.  In addition, the Company leases a portion of the existing Land
O'Lakes pilot plant facility in Arden Hills for its current manufacturing needs
to process polyclonal antibody products for development, early stage clinical
use and potential commercial use.  At the end of 1996, the Company completed its
GMP pilot plant facility and expects it to be fully validated and operational in
the second quarter of 1997.*  Management believes that the Company's facilities
are suitable and adequate for current office, research and manufacturing
requirements.

ITEM 3.  LEGAL PROCEEDINGS

    The Company is not a party to any material legal proceeding.

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

    None.

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

GENERAL

    The Company is developing oral therapeutics which target life-threatening
and infectious diseases such as those caused by antibiotic-resistant and
emerging pathogens.  The Company's pathogen-specific polyclonal antibodies are
produced in concentrated form from bovine colostrum.  The Company's products in
development address serious gastrointestinal infections which complicate cancer,
antibiotic therapy, peptic ulcer disease and immunocompromised and HIV/AIDS
patients.  The Company's lead product in development, SPORIDIN-G, is a
polyclonal antibody product with specificity for C. PARVUM, a parasite which
causes chronic, life-threatening diarrhea in immunocompromised patients.

    The Company believes that certain of its products in development face a
shorter and less expensive path to regulatory approval than many other
biopharmaceutical products.* The Company's lead product in development addresses
a critical need of immunocompromised patients who are inadequately treated by
existing technologies. The Company believes this product may, therefore, qualify
for expedited regulatory review.* Because the Company's products are derived
from cows' milk, they do not represent new chemical compounds with uncertain
toxicity, but rather their components are constituents of dairy foods that are
already widely consumed. Multiple products can be manufactured using a single,
proprietary manufacturing process and facility, and as a result the Company
believes that additional products will not require separate investments in
manufacturing facilities or process techniques.*

RESULTS OF OPERATIONS

YEARS ENDED DECEMBER 31, 1996, 1995 AND 1994

    GENERAL.  The net loss applicable to common stockholders increased by
$9,309,553, or 170%, in 1996 to $14,783,591 from $5,474,038 in 1995 and
increased by $80,004, or 1.5%, in 1995 from $5,394,034 in 1994. The increase in
1996 was due primarily to a one time non-cash charge to earnings in April 1996
of $7,296,844 for a preferred stock dividend, as described below,  relating to
the value of additional shares issued to holders of certain preferred stock 
upon conversion into Common Stock at the closing of the Offering.  Historical
spending levels are not indicative of future spending levels because the Company
is entering a period of rapid growth in product development activity, which is
planned to include increases in costs relating to personnel, research and
development activity, small-scale manufacturing and accelerated clinical trial
activity.  For these reasons, the Company believes its expenses and losses will
increase before any material product revenues are generated.*

    RESEARCH AND DEVELOPMENT EXPENSES.  Expenses for research and development
increased $1,526,543, or 40.9%, in 1996 to $5,257,620 from $3,731,077 in 1995
and increased $288,761, or 8.4%, in 1995 from $3,442,316 in 1994.  The increase
in 1996 was due primarily to increased expenses associated with the SPORIDIN-G
Phase II/III clinical trial, as well as increased development and clinical
expenses for the Company's other products, including CANDISTAT-G, DIFFISTAT-G
and PYLORIMUNE-G and increased associated personnel expense. The increase in
1995 as compared to 1994 was due primarily to a $300,000 license fee paid to
Chiron Corporation in 1995 in the form of 17,143 shares of Series F-1
Convertible Preferred Stock of the Company for use of Chiron's proprietary
adjuvant in SPORIDIN-G. Excluding the license fee, there would have been a
slight decrease from 1994 to 1995 due primarily to the termination of the
Company's transgenics program in early 1995 offset by increases associated with
the development of SPORIDIN-G, including clinical trials, colostrum procurement,
processing and formulation.  The Company incurred approximately $1,210,000,
$559,000 and $191,000 in expenses related to regulatory consultants in 1996,
1995 and 1994 respectively. The Company expects research and development
expenses to increase as the Company's clinical trials activity accelerates.*

    GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative expenses
decreased $132,840, or 6.6%, in 1996 to $1,889,359 from $2,022,199 in 1995 and
increased $301,749, or 17.5%, in 1995 from $1,720,450 in 1994.  The decrease in
1996 compared to 1995 was due primarily to a decrease of $136,200 in deferred
compensation (see Note 7 of Notes to Financial Statements).  The increase in
1995 compared to 1994 related primarily to $476,266 expensed as part of deferred
compensation amortization and costs associated with hiring new employees.

    INTEREST INCOME.  Interest income was $605,548 in 1996, $30,526 in 1995 and
$28,842 in 1994.  The increase in interest income in 1996 was due to the
investment of funds received by the Company from the Offering.

    INTEREST EXPENSE.  Interest expense was $945,316 in 1996, $506,709 in 
1995 and  $260,110 in 1994. Interest expense for 1996 was due primarily to 
warrants valued at $768,064 which were issued to guarantors of a line of 
credit for the Company and to purchasers of the Company's promissory notes 
and to interest over a period of approximately three months on the 
convertible promissory notes issued by the Company (the "Convertible 
Promissory Notes").  The Convertible Promissory Notes converted into 
Common Stock upon the closing of the Offering.  Interest expense for 1995 and 
1994 related primarily to interest on the Convertible Promissory Notes.

    EXTRAORDINARY GAIN ON EXTINGUISHMENT OF DEBT.  The extraordinary gain on
extinguishment of debt of $605,421 in 1995 related to certain debt reduction
settlements negotiated in connection with the termination of the Company's
transgenics program.

                                      23
<PAGE>

    PREFERRED STOCK DIVIDEND.  The preferred stock dividend of $7,296,844 in
1996 related to the value of additional Common Stock received by the holders of
Convertible Promissory Notes, Series E and Series F-1 Preferred Stock upon the
conversion of such securities into Common Stock at closing of the Offering (the
Convertible Promissory Notes converting first into Series D Preferred Stock
which in turn converted immediately into Common Stock at the closing).  The
Convertible Promissory Notes and the Series  D, Series E and Series F-1
Preferred Stock provided that their  conversion prices be automatically adjusted
to reflect the lower of their currently effective conversion price or 70% of the
Offering price.

LIQUIDITY AND CAPITAL RESOURCES

    The Company was incorporated in March 1992.  On July 24, 1992, Procor, the
Company's predecessor, was merged with and into the Company (the "Procor-GalaGen
Merger").  At the time of the Procor-GalaGen Merger, Procor was a wholly-owned
subsidiary of Land O'Lakes.  Since the Company's inception through December 31,
1996, investments in the Company have totaled approximately $50.6 million,
including approximately $7.1 million of inter-company obligations payable to
Land O'Lakes which were forgiven and recorded as contributed capital at the time
of the Procor-GalaGen Merger, $17.9 million from the Offering (after deducting
underwriting discounts and offering expenses) and approximately $25.6 million
from private placements of equity and convertible debt and from conversion of
accrued interest on such debt and the exercise of stock options and warrants. 
The Company has invested funds received in the Offering and these private
placements in investment-grade, interest-bearing obligations.

    Cash used in operating activities increased by $2,903,924, or 89.9%, in
1996 to $6,135,812 from $3,231,888 in 1995 and decreased by $1,317,365, or 29%,
in 1995 from $4,549,253 in 1994.  Cash used in operations went primarily to fund
operating losses and was offset slightly by changes in operating assets and
liabilities.

    In 1996, the Company invested $7,498,343 in available-for-sale securities
and $1,264,342 in equipment and tenant improvements related to the Company's
pilot plant manufacturing facility.  The Company invested $193,012 in 1996,
$36,311 in 1995 and $22,820 in 1994 in lab equipment, computer equipment and
software and furniture used primarily to support the Company's operations. 

    The Company's five-year operating lease for manufacturing equipment
requires future annual minimum payments of approximately $140,000 (see Note 8 of
the Notes to the Financial Statements).

    The Company anticipates that its existing resources and interest thereon
will be sufficient to satisfy its anticipated cash requirements through
approximately the first quarter of 1998.* The Company's working capital and
capital requirements will depend upon numerous factors, including the progress
of the Company's clinical trials and research and development programs and the
timing of and cost of obtaining regulatory approvals.  The Company's capital
requirements also will depend on the levels of resources devoted to the
development of manufacturing and marketing capabilities, technological advances,
the status of competitive products and the ability of the Company to establish
strategic alliances to provide research and development funding to the Company. 

    The Company expects to incur substantial additional research and
development and other costs, including costs related to clinical studies, as
well as capital expenditures necessary to obtain licensure of the existing GMP
pilot plant facility and to establish additional commercial scale GMP
manufacturing facilities. The Company will need to raise substantial additional
funds for longer term product development, manufacturing and marketing
activities it plans to undertake in the future.  The Company's ability to
continue funding its planned operations beyond the first quarter of 1998 is
dependent upon its ability to obtain additional funds through equity or debt
financing, strategic alliances, license agreements or from other financing
sources.  A lack of adequate funding could eventually result in the insolvency
or bankruptcy of the Company.  At a minimum, if adequate

                                      24
<PAGE>

funds are not available, the Company may be required to delay or to eliminate 
expenditures for certain of its product development efforts or to license to 
third parties the rights to commercialize products or technologies that the 
Company would otherwise seek to develop itself.  Because of the Company's 
significant long-term capital requirements, it may seek to raise funds when 
conditions are favorable, even if it does not have an immediate need for such 
additional capital at such time.  If the Company has not raised funds prior 
to such time as the Company's needs for funding become immediate, the Company 
may be forced to raise funds when conditions are unfavorable which could 
result in dilution to the Company's current stockholders.

                         REPORT OF INDEPENDENT AUDITORS


Board of Directors
GalaGen Inc.


     We have audited the accompanying balance sheets of GalaGen Inc. (a 
development stage company) as of December 31, 1996, and 1995, and the related 
statements of operations, changes in stockholders' equity (deficiency) and 
cash flows for each of the three years in the period ended December 31, 1996, 
and for the period from November 17, 1987, (inception) to December 31, 1996. 
These financial statements are the responsibility of GalaGen's management. 
Our responsibility is to express an opinion on these financial statements 
based on our audits. 

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

     In our opinion, the financial statements referred to above present 
fairly, in all material respects, the financial position of GalaGen Inc. at 
December 31, 1996 and 1995 and the results of its operations and cash flows 
for each of the three years in the period ended December 31, 1996 and for the 
period from November 17, 1987, (inception) to December 31, 1996, in 
conformity with generally accepted accounting principles.

1.  DESCRIPTION OF BUSINESS

    GalaGen Inc. is developing oral therapeutics to treat and prevent a broad 
range of human gastrointestinal ("GI") diseases.  Using its proprietary 
processes, the Company has produced polyclonal antibodies that target 
specific pathogens infecting the human GI tract, including bacteria and their 
toxins, parasites, fungi and viruses.  These polyclonal antibodies are 
derived from bovine colostrum, the milk collected in the first few milkings 
of a dairy cow after its calf is born.  When polyclonal antibodies are 
administered orally to humans, they can provide passive immunity within the 
GI tract.  The Company believes that its pharmaceutical products could offer 
an attractive therapeutic alternative to traditional antibiotics at a time 
when increasing antibiotic resistance and emerging new pathogens are becoming 
more prevalent.

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CASH EQUIVALENTS

    Cash equivalents include short-term highly liquid investments purchased 
at cost, which approximates market, with original maturities of three months 
or less.

INVESTMENTS

    Investments in debt securities with a remaining maturity of more than 
three months at the date of purchase are classified as marketable securities. 
Management determines the appropriate classification of debt securities at 
the time of purchase and reevaluates such designation as of each balance 
sheet date. Debt securities are classified as available-for-sale as of 
December 31, 1996. The book value of the investments approximates their 
estimated market value. The estimated market value of investments by security 
type are as follows:

RESEARCH AND DEVELOPMENT COSTS

    All research and development costs are charged to operations as incurred. 


INCOME TAXES

    Income taxes are accounted for using the liability method. Deferred 
income taxes are provided for temporary differences between financial 
reporting and tax bases of assets and liabilities. 

USE OF ESTIMATES

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

NET LOSS PER SHARE

    Net loss per share is computed using the weighted average number of 
shares of common stock outstanding during the periods presented. Pursuant to

83"), the fully diluted shares of common stock outstanding for the periods 
ended 1995 and 1994 have been calculated as the sum of the number of primary 
shares of common stock outstanding, the number of shares convertible into 
common stock upon the conversion of securities issued by the Company at 
conversion prices less than the initial public offering (the "Offering") 
price, using the treasury stock method, during the 12 months immediately 
preceding the Offering which closed on April 1, 1996 and the number of shares 
covered by stock options and warrants granted at exercise prices less than 
the Offering price during the same period.

STOCK BASED COMPENSATION

    The Company has adopted the disclosure-only provisions of Statement of 
Financial Accounting Standards No. 123, ACCOUNTING FOR STOCK BASED 
COMPENSATION ("Statement 123"), but applies Accounting Principles Board 
Opinion No. 25, ACCOUNTING FOR STOCK ISSUED TO EMPLOYEES ("APB 25"), and 
related interpretations in accounting for its stock plans.  Under APB 25, 
when the exercise price of stock options equals the market price of the 
underlying stock on the date of grant, no compensation expense is recognized.

been repaid. 

    In October 1993, the Company borrowed $1,000,000 from a lending 
institution under a line of credit. This line of credit had a variable 
interest rate of 6% at December 31, 1993. A director and an investor 
guaranteed this line of credit in return for two five year warrants to 
purchase 20,312 shares of the Company's common stock. This line of credit has 
subsequently been repaid by the Company and the line of credit terminated. 
See Note 7. 

    In 1993, certain investment funds controlled by Investment Advisers, Inc. 
("IAI"), which has a representative serving on the board of directors of the 
Company, purchased preferred stock in two private placement transactions by

                      NOTES TO FINANCIAL STATEMENTS (CONTINUED)

    Land O'Lakes, IAI, a director and a private foundation controlled by a 
director purchased Convertible Promissory Notes in the principal amounts of 
$1,450,000, $1,080,000, $740,000 and $100,000, respectively. Each of these 
note holders also received a five year warrant, exercisable at $11.07 per 
share on a post-split basis, to purchase that number of shares of common 
stock equal to 20% of the principal amount of such holder's Convertible 
Promissory Note divided by $11.07.  See Notes 6 and 7.

    In December 1995 and January 1996, Land O'Lakes, a director and certain 
investment funds controlled by IAI purchased 169,230, 46,154 and 76,923 
shares, respectively, of Series E preferred stock at $3.35 per share.  See 
Note 6.

    In January 1996, the Company entered into a $2.7 million line of credit 
agreement with a commercial bank, which expired with the closing of the 
Company's Offering.  Loans under this line of credit were to be guaranteed by 
six parties and the guarantee was collateralized by letters of credit posted 
by them in the aggregate amount of $2.7 million.  In consideration for the 
guarantees and letters of credit posted by these parties, the Company issued 
warrants to purchase an initial aggregate of 162,011 shares of common stock 
at $7.00 per share. In connection with this transaction a director and Land 
O'Lakes each guaranteed $500,000 of the $2.7 million line of credit, and in 
exchange received a warrant to purchase 30,002 shares of common stock at 
$7.00 per share. See Note 7.

    In January 1996, the Company issued two convertible promissory notes for 
$375,000 and $125,000 to two investment funds controlled by IAI.  The notes 
became due on completion of the Offering.  The notes were convertible into 
Series E preferred stock at the option of the holder.  In connection with 
these notes, the Company issued warrants to purchase 30,001 shares which are 
identical to the line of credit warrants described above.  The notes have 
been repaid.  

    In  June 1996, the Company entered into a five-year lease agreement with 
Land O' Lakes for specified space within the Land O' Lakes facility in 
connection with the Company's pilot plant manufacturing facility.  See Note 8.

    In December 1996, the Company entered into an equipment operating lease 
which was guaranteed by Land O'Lakes.  See Note 8.  

5.  REVERSE STOCK SPLIT

    On January 19, 1996, the Board approved a reverse stock split of 
3.6923-for-1 for the Company's outstanding common stock. The Company's 
stockholders approved this reverse stock split in March 1996. Certain 
information in the financial statements with respect to the common stock and 
to the conversion prices and ratios of the preferred stock have been adjusted 
to reflect this change. The reverse stock split had no effect upon the 
numbers of shares of preferred stock issued and outstanding (as opposed to 
the conversion prices of the preferred stock and the numbers of shares of 
common stock into which the preferred stock converted).

consent the authorization of 15,000,000 shares of preferred stock which was
effective upon the closing of the Company's Offering. 

REDUCTION IN CONVERSION PRICE AND REVERSE STOCK SPLIT

    SERIES A PREFERRED STOCK:

    The effect of the reverse stock split on the stock price of the Series A
preferred stock was to change the conversion price of the Series A preferred
stock from $2.00 per share to $7.38 per share and to change the conversion ratio
from one share of common stock for each share of Series A preferred stock to
0.271 shares of common stock for each share of Series A preferred stock.  All
Series A preferred stock was converted into 677,063 shares of common stock upon
the closing of the Offering.

    SERIES B PREFERRED STOCK AND SERIES C PREFERRED STOCK:

    In March 1994, in order to induce certain of the existing holders of the
Series B and Series C preferred stock to purchase the Notes, the Company's Board
of Directors voted to reduce the conversion price of the Series B preferred 
stock from $3.25 to $2.00 and the Series C preferred stock from $5.00 to $3.00.
The effect of the reductions was to change the conversion ratio of the Series B
preferred stock from one share of common stock for each share of Series B
preferred stock to 1.625 shares of common stock for each share of Series B
preferred stock, and to change the conversion ratio of the Series C preferred
stock from one share of common stock for each share of Series C preferred stock
to 1.667 shares of common stock for each share of Series C preferred stock. 

    The effect of the reverse stock split on the stock price of the Series B
and Series C preferred stock, after the conversion price adjustment described
above, was to change the conversion price of the Series B preferred stock from
$2.00 per share to $7.38 per share and to change the conversion price of the
Series C preferred stock from $3.00 per share to $11.07 per share.  The effect
of the reverse stock split on the conversion ratio, after the conversion price
adjustment described above, is to change the conversion ratio of the Series B
preferred stock from 1.625 shares of common stock for each share of Series B
preferred stock to 0.440 shares of common stock

                      NOTES TO FINANCIAL STATEMENTS (CONTINUED)

for each share of Series B preferred stock, and to change the conversion 
ratio of the Series C preferred stock from 1.667 shares of common stock for 
each share of Series C preferred stock to 0.451 shares of common stock for 
each share of Series C preferred stock.  All Series B and Series C preferred 
stock were converted into 543,413 and 248,758 shares, respectively, of common 
stock upon the closing of the Offering.

    SERIES D PREFERRED STOCK (CONVERTIBLE PROMISSORY NOTES), SERIES E PREFERRED
STOCK AND SERIES F-1 PREFERRED STOCK:

    On a pre-split basis, the conversion ratio of the Series D preferred 
stock, Series E preferred stock and Series F-1 preferred stock into common 
stock were, by their terms, automatically adjusted to reflect the lower of 
the currently effective conversion price of $3.00 per share of Series D 
preferred stock and $3.25 per share of Series E preferred stock and Series 
F-1 preferred stock or 70% of the Offering price.

    The effect of the reverse stock split on the conversion price of the 
Series D, Series E and Series F-1 preferred stock was to change the 
conversion price of the Series D preferred stock to $11.07 per share and to 
change the conversion price of the Series E and F preferred stock to $12.00 
per share or to 70% of the Offering price, whichever is lowest.    Because 
the Offering price was $10.00 per share, the Series D, Series E and Series 
F-1 preferred stock converted into common stock at $7.00 per share.  On a 
post-split basis, the effect of these reductions is to change the conversion 
ratio of 0.271 shares of common stock for each share of Series D preferred 
stock to 0.429 shares of common stock for each share of Series D preferred 
stock, to change the conversion ratio of 0.271 shares of common stock for 
each share of Series E preferred stock to 0.464 shares of common stock for 
each share of Series E preferred stock, and to change the conversion ratio of 
1.458 shares of common stock for each share of Series F-1 preferred stock to 
2.50 shares of common stock for each share of Series F-1 preferred stock. 
These reductions in the conversion prices of the Series D, Series E and 
Series F-1 preferred stock from $11.07, $12.00 and $12.00 per share, 
respectively, to $7.00 per share was valued at $7,296,844 and recorded as a 
preferred stock dividend to arrive at the net loss available to holders of 
common stock in the calculation of net loss per share.   All Series D, Series 
E and Series F-1 preferred stock was converted into 1,434,495,  178,568 and 
85,717 shares, respectively, of common stock upon the closing of the Offering.

EMPLOYEE STOCK PURCHASE PLAN

    In March 1996, the Company adopted the Employee Stock Purchase Plan 
whereby 270,833 shares of common stock have been reserved.  All employees who 
have met the service eligibility requirements are eligible to participate and 
may direct the Company to make payroll deductions of one to 10 percent of 
their compensation during a purchase period for the purchase of shares under 
the plan. Participants may purchase up to 5,000 shares of common stock for a 
given purchase period provided the fair market value of the stock is not more 
than $25,000 (determined at the beginning of each purchase period).  The plan 
provides a participating employee the right, subject to certain limitations, 
to purchase the Company's common stock at a price equal to the lower of 85% 
of the fair market value of the Company's common stock on the first day, or 
the last day, of the applicable purchase period.  The first purchase 
commenced on July 1, 1996 and ended on December 31, 1996, of which 3,642 
shares of common stock were issued to employees for $13,548. Subsequent 
purchase periods will run for twelve months beginning on January 1.

    Additionally, the Company granted 358,300 options under a proposed 1997
Stock Plan (the "Proposed Plan"), pending stockholder approval in May 1997.
Total shares available under the Proposed Plan are 1,250,000.  Options under the
Proposed Plan were granted at fair market value, vest over three to five years
and expire in ten years.

WARRANTS

    In January 1993, the Company granted a warrant to purchase  13,541 shares
of the Company's common stock at $12.00 per share to an investment banking firm
for financial advisory services.  This warrant expires May 1998.

    In June 1993, the Company granted a warrant to purchase 9,479 shares of the
Company's common stock at $.18 per share to a contract research organization for
services rendered in 1993. Expense was recorded for the difference between the
exercise price and fair market value of the common stock, as determined by the
Board of Directors. This warrant expires December 1998. 

    In October 1993, the Company granted a warrant to purchase 20,312 shares of
the Company's common stock at $18.46 per share to each of a board member and an
investor in return for their guarantee for the Company's line of credit. These
warrants expire October 1998. 

    In connection with the Notes issuance of $8,275,000, each Note holder
received a warrant, exercisable at $11.07 per share, to purchase that number of
shares of common stock equal to 20% of the principal amount of such holder's
Note divided by $11.07. The Company granted warrants to purchase 149,384 shares
of the Company's common stock. These warrants expire five years from the date of
grant, which range from June 1999 to October 2000.

    In March 1995, Chiron was issued warrants to purchase 200,000 shares of the
Company's Series F preferred stock for which the Company was paid $150,000. The
Company issued the warrants to purchase 200,000 shares of Series F preferred
stock to Chiron as follows: (i) warrant to purchase 17,144 shares of Series F-1
preferred stock, exercise price of $17.50 per share (pre-Offering) or $24.00 per
share (post-Offering); (ii) warrant to purchase 42,856 shares of Series F-2
preferred stock, exercise price of $18.70 per share (pre-Offering) or $27.00 per
share (post-Offering); (iii) warrant to purchase 60,000 shares of Series F-3
preferred stock, exercise price of $25.00 per share (pre-Offering) or $33.00 per
share (post-Offering); and (iv) warrant to purchase 80,000 shares of Series F-3
preferred stock, exercise price of $25.00 per share (pre-Offering) or $36.00 per
share (post-Offering). If, after the Company's Offering, the market value (as
defined in the purchase agreement for the warrants) of a share of common stock
is less than the stated post-Offering exercise price of any such warrant, the
exercise price is reduced to such per share market value and the number of
shares of common stock covered by the warrant are increased proportionately.
Based upon the warrant agreements, the ceiling price for the warrants described
in clauses (ii), (iii) and (iv) above were set at the closing of the Offering at
$10.11, $9.24 and $10.08, respectively, per share of common stock.  Chiron
exercised the warrant described in clause (i) above in March 1996 which
converted into 42,860 shares of common stock at the closing of the Company's
Offering.  Assuming the remaining three warrants were exercised in full on
December 31, 1996, 1,355,203 shares of the Company's common stock would have
been issued upon such exercise based upon the twenty day average of the average
of the high and low closing market price, as reported by Nasdaq National Market,
prior to December 31, 1996 of $4.44 per share.   The warrants expire on the
earlier of six years from the date of issuance or 120 days after the warrant
holder receives notice from the Company of the occurrence of certain defined
milestone events.  See Note 10.

    In January 1996, the Company granted  warrants to purchase 162,011 shares
of common stock at $7.00 per share to six parties, one of whom is a Board member
who received a warrant to purchase 30,002 shares of common stock and one of
which is a company which has a representative on the Company's Board which
received a warrant to purchase 30,002 shares of common stock, in return for
their guarantee on the Company's $2.7 million line of credit.  The Company also
granted warrants to purchase 7,500 and 22,501 shares of the Company's common
stock at $7.00 per share to certain investment funds associated  with a
representative on the Company's Board in return for their issuance of two
convertible promissory notes totaling $500,000. These warrants expire February
2001.  The difference between the Offering price and exercise price of these
warrants multiplied by the number of warrants, plus the intrinsic value of the
warrants was $768,064 which was recorded as interest expense in 1996.

STOCK OPTION AND WARRANT AGREEMENT REVISIONS

    In March 1994, the Company canceled all common stock option and warrant
agreements that were issued in 1993 that had exercise prices of $12.00 per share
and $18.46 per share and issued new stock option and warrant agreements with the
same terms and conditions except that the grant prices were $7.38 per share and
$11.07 per share, respectively. 

    In August  1996, the Company canceled all common stock option agreements,
totaling 57,715 shares of common stock under the Plan and 18,958 shares of
common stock outside of the Plan, with the exception of officer and director
options, that were issued with a grant price greater than the fair market value
at the date of re-grant and issued new stock option agreements with the same
terms and conditions except that the grant prices were $5.375 per share.

STOCK-BASED COMPENSATION

    The Company has elected to follow APB 25 and related Interpretations in
accounting for its employee stock options because, as discussed below, the
alternative fair value accounting provided for under Statement 123, requires use
of option valuation models that were not developed for use in valuing employee
stock options.  Under APB 25, if the exercise price of the Company's employee
stock options equals the market price of the underlying stock on the date of
grant, no compensation expense is recognized.

    Pro forma information regarding net loss and loss per share is required 
by Statement 123, and has been determined as if the Company had accounted for 
its employee stock options under the fair value method of Statement 123.  The 
fair value for these options was estimated at the date of grant using the 
Black-Scholes option pricing model with the following weighted-average 
assumptions for 1996 and 1995: risk-free interest rates approximating 6.2%; 
volatility factor of the expected market price of the Company's common stock 
of .527 and a weighted-average expected life of the option of 5 years.

    The Black-Scholes option valuation model was developed for use in
estimating the fair value of traded options which have no vesting restrictions
and are fully transferable.  In addition, option valuation models require the
input of highly subjective assumptions.  Because the Company's employee 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, in management's opinion, the existing models may
not necessarily provide a reliable single measure of the fair value of its
employee stock options.

    For purposes of pro forma disclosures, the estimated fair value of the
options is amortized to expense over the options' vesting period.  The Company's
pro forma information is as follows:

<TABLE>

                                                                        1996           1995
                                                                        ----           ----
<S>                                                                  <C>            <C>
Pro forma amortized expense ......................................   $    165,762      $     1,763
Pro forma net loss applicable to common stockholder...............   $(14,949,353)     $(5,475,801)
Pro forma net loss per common share, fully diluted................   $      (2.26)     $     (1.15)
</TABLE>

The pro forma effect on net loss for 1996 and 1995 is not representative of the
pro forma effect on net loss in future years because it does not take into
consideration pro forma compensation expense related to grants made prior to
1995.

DEFERRED COMPENSATION

    In December 1995, the Company canceled certain stock option agreements
within the Plan and certain stock options that were outside of the  Plan that
had grant prices ranging from $7.38 per share to $11.07 per share and issued new
stock option agreements with the same terms and conditions except that the grant
prices were $3.69 per share. The Company recorded $1,657,000 as deferred
compensation for the difference between the new grant price per share of common
stock and the fair market value of the common stock per share on the date of
grant, as determined by the board of directors, multiplied by the total number
of options effected.  In December 1996, the Company adjusted the deferred
compensation balance to $1,395,800 to account for terminated employee options
that were not vested. The deferred compensation is amortized ratably over the
vesting period of the options.  In 1996 and 1995, $340,066 and $476,266 was
amortized, respectively.   

    The remaining deferred compensation is expected to be amortized as follows: 

     1997...........................................    $  273,868
     1998...........................................       207,200
     1999...........................................        96,400
     2000...........................................         2,000

written notice. 

    The royalties on the above agreements range from one to four percent of
certain net sales.


LEASE COMMITMENTS

    The Company leases certain office equipment under operating leases.

    During June 1996, the Company entered into a five year lease agreement with
Land O' Lakes for specified space within the Land O' Lakes facility in
connection with the Company's pilot plant manufacturing facility.  The lease
calls for annual payments of approximately $87,000 and can be extended for
additional one year periods at the option of the Company.

    In December 1996, the Company entered into an operating lease with Cargill
Leasing Corporation for $835,393 of manufacturing equipment for the Company's
pilot plant facility.  Lease payments of $10,990 per month plus tax will
continue for a period of seven years with the Company's option to extend for an
additional 12 months.  The rental percentage was computed on a weighted average
of the 30 day LIBOR rate and the rate on five year U.S. Treasury Notes. The
lease is guaranteed by Land O' Lakes.

    The total lease expense was $3,133, $9,547 and $29,674 respectively, for
the years ended December 31, 1996, 1995, and 1994. The future minimum annual

                          ----------

9.   INCOME TAXES

    Prior to the effective date of the merger with Procor, GalaGen's losses
were utilized by Land O'Lakes in its consolidated tax return. Subsequent to the
effective date of the merger and through December 31, 1996, GalaGen has
operating loss carryforwards to offset future taxable income of approximately
$27,650,000 which begin to expire in 2007. No benefit has been recorded for such
loss carryforwards, and utilization in future years may be limited, if
significant ownership changes have occurred.

10.  AGREEMENTS

    In March 1995, the Company entered into a License and Collaboration
Agreement with Chiron Corporation involving the licensing of Chiron adjuvant
technology and a collaboration to research and develop passive immune therapies
using bovine antibodies for certain products. Pursuant to this Agreement, Chiron
has granted an exclusive worldwide license for certain of Chiron's proprietary
adjuvant technology to the Company for which the Company issued 17,143 shares of
its Series F-1 preferred stock to Chiron. Additionally, Chiron has been granted
certain rights to exclusively market a certain product for which the Company was
paid $100,000.  See Note 7.

    In October 1995, the Company licensed certain rights of certain technology
to a worldwide developer and marketer of veterinary products. In return, the
Company received an upfront license fee and will receive annual continuation
fees and royalty fees based upon third party sales. 

11.  EXTRAORDINARY ITEM

    In July 1995, the Company terminated its fund raising efforts for its
wholly-owned subsidiary, Altra Bio Inc., and sold the Corporation to a former
officer for the nominal consideration of $1.00. Altra Bio had no book value at
the time of the sale and, accordingly, no gain or loss was recognized in the
transaction. As part of the terminated fund raising efforts, the Company has
negotiated debt reduction settlements with certain research collaborators and a
vendor in the aggregate amount of $605,421.

     2.4  Propagation and Initial Purification will be conducted and the data
          collected, reported and retained in a manner and form consistent with
          applicable current Good Laboratory Practices.  Subsequent steps in
          the Manufacture of [***CONFIDENTIAL TREATMENT REQUESTED; PORTION
          OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION***] will be conducted and the data collected, reported and
          retained in a manner and form consistent with applicable current Good
          Manufacturing Practices.
  
     2.5  CARE shall notify GalaGen, in writing, of any proposed change(s) to
          SOPs prior to implementation of the change.  Implementation of any
          such change shall require the written consent of GalaGen.
  
     2.6  After the Initial Purification and prior to Sterilization, CARE shall
          collect a small quantity of [***CONFIDENTIAL TREATMENT REQUESTED;
          PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION***], as specified by GalaGen, and provide this to GalaGen
          for use as an assay reagent.  After completing Sterilization and prior
          to beginning Inactivation, CARE shall submit a sample, as specified by
          GalaGen, from each container of [***CONFIDENTIAL TREATMENT REQUESTED;
          PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION***], to GalaGen.  GalaGen shall test each sample taken
          after Sterilization for sterility, concentration, quantity and
          identity according

                                       3

          to the following.  CARE shall not proceed with Inactivation until
          receiving notice from GalaGen that testing confirms sterility,
          concentration, quantity and identification specifications.
  
          2.6.1  Sterility - The sample shall be tested for sterility according
                 to current USP test methods and must pass.  If the testing does
                 not confirm sterility, then CARE shall repeat Sterilization and
                 resubmit samples to GalaGen for testing.  If required, repeat
                 Sterilization will be performed within five working days of
                 GalaGen's notification to CARE to repeat Sterilization.
  
          2.6.2  Concentration of [***CONFIDENTIAL TREATMENT REQUESTED;
                 PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND
                 EXCHANGE COMMISSION***] shall be determined by direct count
                 (hemocytometer) and shall be [***CONFIDENTIAL TREATMENT
                 REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES
                 AND EXCHANGE COMMISSION***]/ml.  If the testing does not
                 confirm this concentration, then CARE shall adjust the
                 [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED
                 SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***]
                 concentration and resubmit samples to GalaGen for testing.
                 If required, concentration adjustment will be performed within
                 5 working days of GalaGen's notification to CARE to adjust
                 concentration. 
  
          2.6.3  Quantity shall be determined by multiplying the concentration
                 of [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED
                 SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***]
                 determined in Section 2.6.2 by the total volume of

     10 working days of receiving notice to proceed.  In the event of
     reprocessing of [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED
     SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] according to
     2.6.1 or 2.6.2, the resubmitted samples must meet all specifications before
     proceeding to Inactivation.
  
     2.7  CARE shall complete a quality review of each Lot that includes a
          review of all Manufacturing documentation for accuracy, completeness
          and consistency and to determine compliance with approved procedures
          prior to submitting Lot documentation to GalaGen.
  
     2.8  CARE shall submit documentation for each Lot to GalaGen within
          10 working days of completing Inactivation.  Documentation shall
          include a batch record and copies of certain raw data as requested
          by GalaGen.
  
     2.9  There will be no guarantee by CARE of the quality and/or number of
          [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED SEPARATELY
          WITH THE SECURITIES AND EXCHANGE COMMISSION***] submitted to GalaGen
          from each Lot; provided, however, that only [***CONFIDENTIAL TREATMENT
          REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND
          EXCHANGE COMMISSION***] that have been Propagated and undergone
          Initial Purification, Sterilization and Inactivation according to
          approved SOPs, have been confirmed as sterile and in compliance with
          and meeting the specifications contained in Section 2.6 will be
          accepted by GalaGen.  GalaGen shall conduct a review of documentation
          submitted by CARE after Inactivation and shall be responsible for
          determining whether [***CONFIDENTIAL TREATMENT REQUESTED; PORTION
          OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION***] from a Lot meet such specifications and whether
          documentation is acceptable.  GalaGen shall notify CARE, in
          writing within 30 days of receipt of documentation, if the Lot

                                      5
<PAGE>

          passes or fails GalaGen's review.  CARE will not perform Distribution
          of a Lot until the Lot is released by GalaGen.
  
   2.10   Between the Manufacture of Lots, CARE shall be responsible for
          maintaining a minimum of two separate stock solutions of
          [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] according
          to agreed upon procedures and shall use its best efforts to prevent
          loss or destruction of such "seed stocks".  GalaGen shall be notified
          immediately, in writing, if there is any actual or suspected loss,
          contamination, destruction, etc. of such stocks between Manufacture
          of Lots.
  
  3. VALIDATION
  
     3.1  GalaGen and CARE shall be jointly responsible for developing a
          Validation Master Plan (the "Plan") that identifies what is to be
          validated and the acceptance criteria for each validation to be
          executed.
  
     3.2  The Plan shall be executed by GalaGen and CARE personnel as identified
          in the Plan.
     
     3.3  GalaGen shall be responsible for supplying analytical testing used in
          execution of the Plan and selecting and reimbursing any consultants
          retained for Validation.
     
     3.4  CARE shall be responsible for providing the facility, personnel and
          equipment, at its expense, in the execution of the Plan; however
          GalaGen shall reimburse CARE for personnel time in the execution of
          the Plan.  Such time shall be documented by CARE and submitted to
          GalaGen.  GalaGen shall reimburse CARE at the rate of $60/hour in 1996
          and $63/hr in 1997.  Compensation for Validation or re-Validation
          required in later years shall be negotiated as needed.  
     
     3.5  Once the Manufacture has been Validated according to the Plan any
          subsequent validation required pursuant to Section 2.5, made at the
          request of CARE, shall be executed and paid for by CARE.  If changes
          are made not at the request of CARE then GalaGen shall compensate CARE
          for personnel time expended to implement the change in accordance with
          Section 3.4.

          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] for
          purposes of provision of retrieved [***CONFIDENTIAL TREATMENT
          REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES
          AND EXCHANGE COMMISSION***] to any other individual or entity
          except GalaGen.  
     
     5.2  CARE has the right, as this is the usual type of business in which
          they are engaged, to perform research projects, unrelated to GalaGen,
          in which pharmaceutical or biological products are tested for efficacy
          against [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] in
          [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***].  CARE
          will not conduct other testing in [***CONFIDENTIAL TREATMENT
          REQUESTED; PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND
          EXCHANGE COMMISSION***] used for Manufacturing of GalaGen's Lots
          during the period in which a Lot is being Manufactured.
  
  6. SCHEDULING
  
     6.1  Lots will be Manufactured at least approximately every three
          (3) months and at most twice per month.

     6.2  Both parties recognize that [***CONFIDENTIAL TREATMENT REQUESTED;
          PORTION OMITTED FILED SEPARATELY WITH THE SECURITIES AND EXCHANGE
          COMMISSION***] viability must be maintained via in vivo Propagation
          minimally every three (3) months, thus scheduling will accommodate
          said requirement.  Each Lot will be Manufactured using a minimum of
          two (2) [***CONFIDENTIAL TREATMENT REQUESTED; PORTION OMITTED FILED
          SEPARATELY WITH THE SECURITIES AND EXCHANGE COMMISSION***] and a
          maximum of sixteen (16) [***CONFIDENTIAL

          SECURITIES AND EXCHANGE COMMISSION***].

        If GalaGen places an order, in writing, for a Lot at least six
        (6) months prior to the desired completion of Manufacturing then
        CARE shall guarantee the availiability of facilities for the
        Manufacture of that Lot. Shorter advance notice will be accommodated
        by CARE if possible dependent upon prior commitments, but in any
        case CARE will complete Manufacturing of an order for any Lot no
        later than six (6) months from the time the order is received by
        CARE.

Dear Francois:

I am pleased to offer you employment for the position of Vice President, 
Scientific and Regulatory Affairs. Your responsibilities will include 
management of clinical development, regulatory strategy and regulatory 
oversight for the product portfolio in development. The start date will be 
December 30, 1996.  You will report to the President and you will supervise 
such employees as are assigned in the above functions.

- -  Your salary will be $150,000 annually, payable in twice monthly periods, 
   which shall be reviewed annually and increased in keeping with the Company's 
   general compensation practices.

- -  You will be entitled to receive up to a $50,000 cash bonus per annum (or 33% 
   of base salary).  The size of the bonus received will be based upon the 
   achievement of personal and corporate objectives, as approved by the Board of
   Directors.

- -  An option to purchase 55,000 shares of the Company's common stock, 
   exercisable at market value as of your starting date of employment, and 
   vesting over 5 years.  This grant will require the approval of the Board of 
   Directors and will be governed by the provisions of the Company's stock 
   option plan.

- -  Participation in the Company's senior management incentive compensation 
   program, which may include either cash and/or stock options, and which is 
   presently under review by the Board's Compensation Committee.

- -  Relocation assistance, according to the Company's present relocation policy 
   and guidelines, which is designed to minimize the inconvenience to you and 
   your family of moving.  A summary of this policy and guidelines is attached.
   This policy plan has a number of valuable cash benefits and service options, 
   including advisory and coordinating services through our Relocation Services 
   advisor.  There are tax implications to this package which you should review 
   carefully with your advisors.

- -  Participation in the Company's employee benefit program, a summary of which 
   is attached, and which is subject to change from time to time: 

     -  You and your family will be eligible for immediate healthcare, dental,
        life and long-term disability insurance coverage under this plan.

     -  You will also be eligible for immediate participation in the 401(k)
        retirement plan, which provides for the tax-free investment of a portion
        of your salary for retirement purposes.  There is at present not a
        corporate matching contribution to this plan.

     -  You will also be eligible for participation in the employee stock
        purchase plan beginning in 1998, which will enable you to use up to 10%
        of your salary to purchase company stock at a 15% discount to the lower
        of market price at the beginning or end of the plan year.

     -  In addition to the group life insurance of $500,000, an individual key
        man term life insurance policy of $500,000 will be available to you;
        both policies require a medical examination.  The total $1,000,000 in
        term life insurance will be split 50:50 with your spouse and GalaGen.

You will be required to sign the following standard documents:
 
- -  Employee Confidentiality Agreement
- -  Invention and Trade Secret Agreement
- -  Conflicts of Interest and Business Ethics
- -  Policies Regarding Confidentiality and Securities Trading and Annual
   Certification Form
 
These are routine and in the normal course of business and to confirm that 
you will not be encumbered in any way by non-competitive clauses relative to 
your recent employment.
 
Your original term of employment will be one year; thereafter, either party 
may terminate this agreement on 90 days advance written notice unless 
termination is for cause.
 
Your acceptance of the relocation assistance package and any modifications to 
that policy which are made in writing is contingent upon your signing the 
Relocation Agreement, which is attached, in which you agree that in the event 
that you resign voluntarily your employment relationship with the Company 
within thirty-six months from the effective date of transfer, you will be 
responsible for repaying the Company a portion of the relocation expenses, as 
outlined in the Agreement.

If you accept this offer, the terms described in this letter shall be the 
terms of your employment.  Any additions or modification of these terms must 
be in writing and signed by you and the Chairman of the Board or Chief 
Executive Officer.

Sincerely,

/s/ Robert A. Hoerr

family so that their time is effectively utilized.  See also Destination
Services, Section III.


II. PROPERTY BENEFITS:  Old Location
                        Assistance in Home Sale at previous residence

Homeowners:

To be eligible for this benefit, the individual must be a current home owner.
The residence involved must be the principle dwelling of the individual and
their family.  Seasonal residences, such as vacation cabins, and properties
acquired for commercial and/or investment purposes do not qualify under this
program.

BRM will provide for the individual the MasterChoice Program and the Amended
Value Sale Program, designed to assist the individual to sell their home in the
shortest amount of time for the highest possible price.  Under this program, The
Company, through BRM, will cover the individual's listing commission and
reasonable seller paid closing costs, not to exceed $25,000.  The BRM Real
Estate Specialist assigned to assist the individual will provide the specific
details of the program and the procedures that must be followed to meet IRS
guidelines.  The Company reserves the right to not do the Amended Value Sale
Program should it not be financially advantageous to the Company.  However,
whatever assistance the Company provides to the individual will create no
monetary disadvantage to the individual compared to the Amended Value Sale
Program.

Following the individual's purchase of a new residence, the Company will assume
responsibility for the payment of the monthly mortgage and taxes for the
individual's existing property in Montreal for a period of up to six months or
until such time as the property in Montreal can be sold.  Should the property in
Montreal not sell within six months of the date of purchase of a new property in
the Twin Cities area, the Company will intervene in the process and will assist
in the disposition of the Montreal property.  The Company reserves the right to
employ the most expeditious methods to dispose of the obligation at that point
including the use of various liquidation services or other methods.  Should the
residence sell for CN$260,000 or greater, the Company will not provide any
additional financial assistance.  Should the residence sell for CN$220,000 or
more but less than CN$260,000, the Company will provide the difference between
CN$260,000 and the selling price of the residence.  Should the residence sell
for less than CN$220,000, the Company will provide CN$40,000 plus the difference
between CN$220,000 and the selling price of the new residence, provided that the
difference between CN$220,000 and the selling price of the residence be paid

<PAGE>

back to the Company by withholding one half of the future cash bonus payments as
earned until such amount is recovered.

Should the individual choose to market the home without the services of BRM and
with an agent of their choice, the Company will reimburse only the listing
commission paid by the individual, to a maximum of seven (7) percent of the sale
price of the home and a maximum dollar amount of $15,000.  This reimbursement
will be considered taxable income and the appropriate withholding taxes will be
deducted from the reimbursement.


III. DESTINATION SERVICES:    New Location
                                         Assistance in the Purchase or Rental
                                         of New Residence

The Company has arranged for BRM to provide the MasterChoice "Buy Smart"
Counseling Program for individuals interested in purchasing a new home.  The
purpose of this program is to provide the relocating family with good
information and resources so that they may make a wise home buying decision.
The BRM Real Estate Specialist will coordinate this program for the relocating
family.

The Company will reimburse the transferee for traditional, according to local
custom and law, buyer paid closing costs on a new home purchase up to a maximum
of five points (5% of mortgage amount, not to exceed $15,000).  All closing
costs must be approved by the BRM Real Estate Counselor prior to closing.

The Company will also provide assistance in applying for and obtaining a
mortgage on a new residence.  This will include providing a payment of 5% of the
purchase price of a new residence (up to a maximum new resident value of
$300,000).

These benefits must be utilized by nine (9) months from the signing of this
agreement.


IV. HOUSEHOLD GOODS SHIPMENT

The transportation of the individual's household goods and one automobile
shipment will be arranged by BRM.  The Company will pay the cost of packing,
transporting, and unpacking of the individual's "normal" household items from
the former to the new residence.  "Bulky" or "Unusual" items such as boats,
trailers, frozen food, firewood and large shop machinery and so forth, will be
excluded from the items the Company will cover and would be the responsibility
of the individual.  (Your BRM Relocation Counselor will give you a Household
Moving Procedures Brochure which addresses the specific guidelines.)

Appliance Service fees will be paid by the Company up to a maximum of $500.00.
If necessary, the Company will pay for up to 30 days temporary storage charges
if the individual is unable to occupy his/her new residence immediately.

The maximum dollar coverage for the Household Good Shipment (including temporary
storage if necessary) benefit is $15,000.  Any expenditure above that amount
will be the responsibility of the transferee.

V.  MISCELLANEOUS RELOCATION ALLOWANCE

In addition to the expense reimbursements described elsewhere in this policy,
the Company will provide a Relocation Allowance.  The Allowance is intended to
assist the person with other relocation related expenses.  The amount of the
Allowance is $2,500.  Appropriate taxes will be withheld.


<PAGE>

This Allowance will be paid the first pay period after the official start date
at the Company.


VI. TAX IMPLICATIONS OF RELOCATION

Corporate relocation has significant income tax implications.  Most relocation
expense reimbursements are considered taxable income to the individual and must
be reported as such to the IRS.

The expenses the Company reimburses for the Residence (Section I) and  a portion
of the Property Benefits (Section II) and Destination Services (Section III) are
considered income.  The Company will provide a contribution, or "gross-up",
toward the potential tax liability of these approved expenses.

Because of the complexity of income tax regulations related to relocation, the
company recommends that the individual seek competent tax advice in the
preparation of income tax returns.


VII. RELOCATION AGREEMENT

Prior to the authorization of any relocation benefits, the Company requires the
relocating individual to read and sign a Relocation Agreement.  This agreement
provides that if the individual voluntarily terminates with the Company within
thirty six (36) months of their relocation, they would be responsible for
repayment of a portion of the relocation benefits.

                                     The Company
                                 RELOCATION AGREEMENT

     This is an agreement by and between the Company and Dr. Francois Lebel.  In
consideration of the mutual promises and agreements, the terms and conditions
set forth herein and contained in the Company Relocation Package extended said
person, it is agreed as follows:

1.  The Company will pay on behalf of the individual all authorized relocation
expenses as explained in the Company Relocation Package and associated with the
individual's relocation from Montreal, Quebec, Canada to the Twin cities of
Minnesota.

2.  The Company agrees that if the individual remains with the Company's for
thirty six (36) full months from the effective date of the relocation, the
individual shall have no obligation to repay any of the relocation expenses.

3.  The individual agrees that in the event the individual voluntarily resigns
their relationship with the Company within thirty six (36) months from the
effective date of transfer, the individual will reimburse the Company for the
relocation expenses incurred, at the rate of one thirty sixth (1/36) of the
total expenses for each uncompleted month of service.

4.  The individual's repayment is due and payable upon final date of service.
By executing this agreement, the individual agrees to make repayment in full and
hereby authorizes the Company to effect repayment by either cash payment from
the individual and/or by deducting the repayment from any sums due the
individual on or after the final day of service.

5.  In the event of a subsequent transfer that is effective during the term of
a Relocation Agreement, the current Relocation Agreement will become void,
providing the individual has entered into a Relocation Agreement for the
subsequent transfer.

6.  This Relocation Agreement is not a contract of employment and does not
guarantee employment.  This agreement exists solely to define the Company Policy
pertaining to the repayment of relocation expenses by individuals.

                             CONSULTING CONTRACT

     This document will confirm the agreement between GalaGen Inc. 
("GalaGen"), located at 4001 Lexington Avenue North, Arden Hills, Minnesota, 
55126 and Stanley Falkow, Ph.D. ("Senior Consultant"), located at 8 Longspur, 
Portola Valley, CA 94025, with respect to GalaGen's engagement of Senior 
Consultant as an independent consultant.   Specifically, the parties agree as 
follows:

1.0  SCOPE OF WORK

     1.1  Senior Consultant will be available to provide to GalaGen such 
services related to review of scientific programs, as more fully set forth in 
the attached Schedule A.  Those services will be performed in accordance with 
the terms and specifications, directions and instructions issued by GalaGen 
in written form to Senior Consultant.  Those directions and instructions 
shall constitute the only authorization for Senior Consultant to take any 
action or spend any money.

     1.2  Senior Consultant is an independent consultant performing services 
on a contract basis for a variety of persons and entities.  As an independent 
consultant of GalaGen, Senior Consultant is not authorized to act on behalf 
of GalaGen as its agent or as an employee.  Senior Consultant shall not have 
the right or power to bind GalaGen to any contracts or agreements with any 
third party, nor shall Senior Consultant have the right or power to direct 
any operations of GalaGen.  The relationship created by this Agreement is 
that of a contract for services and nothing herein contained is intended to 
nor shall it create the relationship of employment, partnership, joint 
venture or agency.

2.0  PAYMENT

     GalaGen will pay Senior Consultant for services under this Agreement in 
accordance with the payment schedule set forth in the attached Schedule B.

3.0  CONFIDENTIALITY

     3.1  In performing services on behalf of GalaGen, Senior Consultant will 
be exposed to and will be required to use certain "Confidential Information" 
(as hereinafter defined) of GalaGen.  Senior Consultant agrees not to use or 
disclose, directly or indirectly, such Confidential Information for the 
benefit of any person or organization other than GalaGen, either during or 
after the term of this Agreement, for as long as such information retains the 
characteristics of Confidential Information.  Senior Consultant agrees not to 
disregard its obligations of confidence hereunder by using any trade secret 
or other Confidential Information to guide Senior Consultant in a search of 
publications or other publicly available information, selecting a series of 
items of knowledge from unconnected sources and fitting them together in 
order to support a claim that Senior Consultant did not violate any 
obligations set forth in this Agreement.

     3.2  "Confidential Information" means information not generally known, 
including trade secrets about GalaGen's methods, processes and products, 
including but not limited to information relating to such matters as research 
and development, analysis, manufacturing methods, processes, techniques, 
formulations, data, chemical composition of materials, applications for 
particular technologies or chemical compounds, materials or designs, vendor 
names, customer lists, management systems, and sales and


<PAGE>

marketing plans.  All information disclosed to Senior Consultant or to which 
Senior Consultant has access during the term of this Agreement which Senior 
Consultant has a reasonable basis to believe is Confidential Information or 
which is treated by GalaGen as Confidential Information shall be presumed to 
be Confidential Information.

     3.3  Promptly upon the expiration or termination of this Agreement, or 
upon the request of GalaGen, Senior Consultant shall return to GalaGen all 
documents and tangible items provided to Senior Consultant or created by 
Senior Consultant for use in connection with services to be rendered 
hereunder, including without limitation all Confidential Information, 
together with all copies, recordings, abstracts, notes, reproductions of any 
kind made from or about the documents and tangible items or the information 
contained therein.

4.0  RIGHTS AND DATA

     4.1  All works of authorship, documents and tangible items prepared for 
or submitted to GalaGen by Senior Consultant under this Agreement shall 
belong exclusively to GalaGen and shall be deemed to be works made for hire 
(the "Deliverable Items").  To the extent that any of the Deliverable Items 
may not, by operation of law, be works made for hire, Senior Consultant 
hereby assigns to GalaGen the ownership of copyright work in the Deliverable 
Items, and GalaGen shall have the right to obtain and hold in its own name 
any trademark, copyright, or mask work registration, and any other 
registrations and similar protection which may be available in the 
Deliverable Items.  Senior Consultant agrees to give GalaGen or its designees 
all assistance reasonably required to perfect such rights.

     4.2  To the extent that any pre-existing materials are contained in the 
Deliverable Items, Senior Consultant grants to GalaGen an irrevocable, 
nonexclusive, worldwide, royalty-free license to (a) use, execute, reproduce, 
display, perform, distribute (internally or externally) copies of, and 
prepare derivative works based upon, such pre-existing materials and 
derivative works thereof; and (b) authorize others to do any, some or all of 
the foregoing.

     4.3  In providing services and preparing Deliverable Items hereunder, 
Senior Consultant understands that GalaGen does not wish to receive from 
Senior Consultant any information which may be considered confidential and/or 
proprietary to Senior Consultant or to any third party.  Senior Consultant 
represents and warrants that any information disclosed to GalaGen by Senior 
Consultant hereunder is not confidential and/or proprietary to Senior 
Consultant or to any third party.

     4.4  Senior Consultant represents and warrants the originality of the 
Deliverable Items and that no portion of the Deliverable Items, or their use 
or distribution, violates or is protected by any copyright or similar right 
of any third party.

     4.5  No license or right is granted to Senior Consultant, either 
expressly or by implication, estoppel or otherwise, to use, execute, publish, 
reproduce, prepare derivative works based upon, distribute copies, publicly 
display, or perform the Deliverable Items either during or after the term of 
this Agreement.

after working hours; provided, that either the conception or reduction to 
practice occurs during the term of this Agreement and in connection with the 
performance of services hereunder.

     5.3  Senior Consultant shall (a) promptly and fully disclose and 
describe all Inventions in writing to an officer of GalaGen or anyone else 
designated by GalaGen (such disclosure shall include, if requested, a 
detailed report of the procedure employed and the results achieved by Senior 
Consultant); and (b) give GalaGen all assistance GalaGen requires to perfect, 
protect and use its rights to Inventions, including but not limited to 
signing all documents, doing all things and supplying all information that 
GalaGen may deem necessary or desirable to (i) transfer or record the 
transfer to GalaGen of the entire right, title and interest of Senior 
Consultant and/or Senior Consultant's employees in Inventions, and (ii) 
enable GalaGen to obtain patent, copyright, or trademark protection for the 
Inventions anywhere in the world.

     5.4  The obligations of this paragraph 5.0 shall continue beyond the 
expiration or termination of this Agreement with respect to Inventions which 
Senior Consultant and/or Senior Consultant's employees conceive or make 
during the term of this Agreement.  For purposes of this agreement, any 
Invention relating to the existing or reasonably foreseeable business 
interest of GalaGen for which Senior Consultant and/or Senior Consultant's 
employees file a patent application or any trademark, copyright or mask work 
registration within one (1) year after the termination of this Agreement 
shall be presumed to be an Invention which was conceived during the term of 
this Agreement, subject to proof to the contrary.

NOTICE:  To the extent that Minnesota Statute 181.78 applies, Senior 
Consultant is hereby notified that this Agreement does not apply to an 
Invention for which no equipment, supplies, facility or trade secret 
information of GalaGen was used, and which was developed entirely on Senior 
Consultant's own and/or Senior Consultant's employee's time and (a) which 
does not relate (i) directly to the business of GalaGen, or (ii) to GalaGen's 
actual demonstrably anticipated research or development; or (b) which does 
not result from any work performed by Senior Consultant and/or Senior 
Consultant's employees for GalaGen.

6.0  SENIOR CONSULTANT'S EMPLOYEES NOT DEEMED GALAGEN'S

     Personnel supplied by Senior Consultant will be deemed employees of 
Senior Consultant and will not for any purpose be considered employees or 
agents of GalaGen.  Senior Consultant assumes full responsibility for the 
actions of such personnel while performing services pursuant to any 
directions or instructions of GalaGen issued hereunder, and shall be solely 
responsible for their supervision, daily direction and control, payment of 
salary (including, withholding of income taxes and social security), worker's 
compensation, disability benefits and the like, and shall indemnify and hold 
GalaGen harmless for any and all such expenses, liabilities and obligations.

     their position and level of responsibility in the Company.

VI.  CALCULATION OF INDIVIDUAL BONUSES

     relate to achieved personal objectives and management discretion.  The
     overall objective is to reward superior performance.

     retirement, disability or death will be entitled to a prorated bonus under

<PAGE>

VIII. OTHER TERMINATIONS
      A participant whose employment is terminated during the year for any
      reason other than retirement, disability or death will not be entitled
      to a bonus under this Plan.  Participants must be actively employed on
      the last day of the year to receive an award.  No prorated awards will
      be made.

IX.   ADMINISTRATION
      The Compensation Committee of the Board of Directors shall have the
      full power, authority, and discretion to interpret this Plan and may
      establish such rules, regulations, procedures and guidelines as it
      deems necessary for its administration.

X.    AMENDMENT AND TERMINATION
      The Board of Directors may amend, modify or terminate the Plan, in
      whole or in part, at any time.  No payment of any bonus at any time
      under this Plan may be considered as fixed, earned or accrued until
      actual payment is made.

XI.   MITIGATING FACTORS
      The Compensation Committee of the Board of Directors may decide at its
      discretion, whether and to what extent non-controllable mitigating
      factors, favorable or unfavorable, (e.g. economic conditions,
      embargoes, business "windfalls", ability of company to pay, etc.) will
      be considered in the evaluation process and bonus pool calculation.
      Any exceptions to regular pool funding calculations must be approved
      by the Board of Directors.  The Board of Directors may at its
      discretion direct that awards be made in forms other than cash, such
      as stock options at fair market value.
