INTRODUCTION

     GalaGen Inc. ("GalaGen" or the "Company"), which was incorporated in 
1992 as a successor to a company incorporated in 1987, has expertise in 
obtaining and processing polyclonal antibodies, as follows:

          ACCESS TO COLOSTRUM.  The Company has agreements with Land O'Lakes 
     which provide the Company with access to the Land O'Lakes dairy system. 
     This dairy system has approximately 400,000 cows, from which the Company 
     receives its supply of colostrum, which is milk collected in the first 
     few milkings of a dairy cow after its calf is born.  From this 
     colostrum, the Company obtains its antibodies, which are food proteins.  
     These cows are located primarily in the upper Midwest and both the East 
     and West coasts.

          PROPRIETARY TECHNOLOGY.  Using its proprietary immunization 
     technologies, including the use of immune system stimulating adjuvants, 
     the Company can produce antibodies in the cow that target specific 
     pathogens infecting the human gastrointestinal ("GI") tract, including 
     bacteria and their toxins, parasites, fungi and viruses. This technology 
     increases by many fold a dairy cow's natural production of 
     pathogen-specific antibodies in its colostrum.

          PROPRIETARY MANUFACTURING.  The Company has patented, proprietary 
     manufacturing processes that are used to concentrate antibodies from the 
     colostrum.  Standard dairy processing techniques destroy the activity of 
     most of the antibodies present in milk and colostrum, whereas the 
     Company's processing retains the antibody activity.

     The Company is utilizing this expertise to develop a portfolio of 
proprietary nutritional products, including dietary supplements, which will 
incorporate its Proventra-TM- Brand Natural Immune Components ("Proventra"). 
These products will target needs of both consumers and healthcare 
professionals.*  GalaGen is also developing oral pharmaceuticals that target 
life threatening and emerging pathogens.

     In December 1997, the Company introduced Basics Plus-TM-, a dietary 
supplement product, in conjunction with its marketing and manufacturing 
partner, Lifeway Foods, Inc.  Basics Plus is the first product to emerge from 
the collaboration with Lifeway Foods, Inc.  It contains active kefir 
cultures, which are cultures that contain 


                                       2
<PAGE>

beneficial bacteria strains, and GalaGen's Proventra. Basics Plus is the 
first dairy-based dietary supplement sold in the United States in the 
refrigerated section of health food stores and grocery stores, and is 
currently in test markets in Chicago, New York City and Milwaukee.  The 
product was featured in the February 1998 issue of DAIRY FOODS MAGAZINE.

     Diffistat-G, the Company's lead pharmaceutical product in development, 
is being developed for the treatment and prevention of antibiotic-associated 
diarrhea, a disease that annually affects more than 400,000 patients in the 
United States.

     Because the Company's antibodies, including Proventra, 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.  Antibodies for incorporation into multiple 
nutritional and pharmaceutical 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

GENERAL

     Passive immunity consists of using antibodies produced by one individual 
or animal to treat, prevent or protect against infection in another.  Such 
antibodies can be administered 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.  Through their natural exposure to the 
environment, cows have developed antibodies that recognize and bind to many 
human pathogens.

NUTRITIONAL PRODUCTS

     According to Frost & Sullivan, a competitive-market analysis firm, the 
market for nutraceutical or functional food beverages now exceeds $20 
billion. The Company believes that this significant market size is due to a 
number of factors, including (i) increased interest in healthier lifestyles, 
(ii) the publication of research findings supporting the positive health 
effects of certain nutritional supplements and (iii) the aging of the "Baby 
Boom" generation combined with the tendency of consumers to purchase more 
nutritional supplements as they age.*

     The Company believes that the inclusion of antibodies in nutritional 
products, along with including other components such as active cultures and 
dietary soluble fiber, provide important benefits and competitive advantages, 
including (i) a unique immune-enhancing system, (ii) a fit with consumer 
needs, and (iii) a safe, proven means to fight pathogens.*

PHARMACEUTICALS

     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 body to levels high enough to 
prevent or counteract disease. 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. For these reasons, new 
therapeutic approaches for treating and preventing GI infections are needed. 
One 


                                       3
<PAGE>

alternative to antibiotics and vaccines is passive immunity. As a result of 
these advantages, passive immunity can be used in pharmaceutical applications 
for both acute treatment and long-term prevention of disease.

     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.

THE COMPANY'S CORE ANTIBODY TECHNOLOGY AND PRODUCT BENEFITS

     The Company's products contain polyclonal antibodies derived from bovine 
colostrum, which is the first milk from a cow after her calf is born.  The 
antibodies are orally administered to humans and provide passive immunity 
within the GI tract.  The Company's goal is to provide passive immunity for 
individuals either through regular use of nutritional products that have 
lower concentrations of antibodies over a longer period of time or through 
periodic use of pharmaceutical products that have higher concentrations of 
antibodies over a shorter period of time.*

     The antibodies may block a 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 antibodies in its colostrum.

     Standard dairy processing techniques destroy the activity of most 
antibodies present in milk and colostrum.  The Company's proprietary 
processes used to concentrate antibodies have 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 will manufacture its nutritional products in accordance with the 
appropriate license issued by Minnesota Department of Agriculture ("MDA").  
The Company will manufacture its pharmaceutical products in accordance with 
pharmaceutical specifications for oral dosage formulations and will support 
its proprietary processing system with a quality control system that 
regulates, monitors and reviews the processing system in compliance with 
current Good Manufacturing Practices ("GMP") for the manufacture of biologics.

PRODUCTS IN DEVELOPMENT

NUTRITIONAL PRODUCTS

     In addition to therapeutic products targeted at GI diseases, the Company 
believes that its 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 foods which provide 
benefits beyond their nutritional value.  While there is not a regulatory 
definition for the terms "functional food" or "nutraceutical", these terms 
are widely used in the marketplace.  The Company believes that 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.  DSHEA permits 
such products to bear "structure-function" claims related to how the product 
affects the structure or function of the body, and such claims do not require 
FDA review or approval, but must be supported by scientific evidence.  NLEA 
permits products to carry more specific health claims, but requires FDA 
approval and general scientific consensus to support the claim in question.  
The Company believes that the incorporation of Proventra in foods or dietary 
supplements would add benefits to these products.*


                                       4

     As previously described above, the Company currently has one product, 
Basics Plus, being sold in test markets through its manufacturing and 
marketing partner Lifeway Foods, Inc.  The Company is applying its resources 
to two other products as described below.  The Company does not anticipate 
spending significant resources to market the final products, but will seek to 
find partners with the appropriate distribution and marketing credentials*:

CLINICAL NUTRITION PRODUCT

     The Company is developing a dairy-based nutritional beverage for 
patients in hospitals and nursing homes.  Based upon market research results, 
the Company believes that a need exists for a superior tasting refrigerated 
beverage that will provide Proventra and other active components.*  The 
Company believes that a superior tasting dairy-based beverage, which includes 
a combination of these ingredients, will increase consumption compliance, in 
turn leading to better nutrition, improved defense against infection and more 
regular bowel function.* Clinical evaluation of this product is anticipated 
to begin in the second quarter of 1998.*

CONSUMER NUTRITION PRODUCT

     GalaGen is developing an enhanced beverage product targeted at 
health-oriented consumers.  Market trends indicate that consumers, 
particularly baby boomers and mature adults, are taking a more proactive role 
in managing their health.  The Company believes that a superior tasting 
beverage containing its proprietary immune-enhancing ingredients, including 
Proventra, will be the first product of its kind.*  Product development is 
underway with market research to begin in the second quarter of 1998.*

PHARMACEUTICALS

     The Company believes that its colostrum-derived 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 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. 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 


                                       5
<PAGE>

     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 cancer patients).

          AVOID PROBLEMS ASSOCIATED WITH ANTIBIOTIC USE.  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, 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 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 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 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 one product in development under the first 
tier of products to which it is applying its resources.  The Company does not 
anticipate applying significant resources toward the second tier products but 
will seek to find partners who will fund the required development and 
clinical trials*:

</TABLE>

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. 


                                       6
<PAGE>

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 were 
published in ANTIMICROBIAL AGENTS AND CHEMOTHERAPY in February 1997.  A 
second Phase I bioavailability trial in ileostomy patients was completed in 
February 1997 at Beth Israel-Deaconess Medical Center, Harvard Medical School 
in Boston and demonstrated higher than anticipated recovery of functional 
antibodies in the ileum of these patients.  Based on these positive results, 
the Company initiated a multi-center Phase II clinical trial in August 1997 
to assess safety, efficacy and formulation.  Principal investigators in the 
study are from  Beth Israel-Deaconess Medical Center, Harvard Medical School 
in Boston.  Additionally, 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.  If 
positive results are shown from the Phase II clinical trial, the Company 
anticipates that it will need to secure a partner to continue further 
clinical development and to market Diffistat-G.*

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.  This infection 
occurs in most immunocompromised patients (cancer, organ/bone marrow 
transplant and HIV/AIDS) at some time during their illness.   Short-term 
therapy with traditional antifungal agents 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.  The Company believes 
that an 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.*


                                       7
<PAGE>

     CANDISTAT-G has been prepared by immunizing 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 
CANDISTAT-G treated bone marrow transplant recipients and 
historically-matched controls in a European Phase I/II dose-ranging clinical 
trial at a major teaching hospital in Sweden was completed in the third 
quarter of 1997.  The results from this clinical trial showed that 
CANDISTAT-G provided a reduction in the number of CANDIDA organisms in the 
oral cavity of eight out of eleven highly immunocompromised transplant 
patients with pre-existing CANDIDA colonization. No product related adverse 
events were noted.

PYLORIMUNE-G

     The Company is developing a polyclonal antibody product to treat 
gastritis and ulcers caused by the bacterium H. PYLORI.   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. The Company believes that the limited effectiveness of 
currently available therapies and growing antibiotic resistance offer an 
opportunity for its 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 Corporation ("Chiron") for the development of colostrum-based 
antibody products to treat H. PYLORI. Chiron's participation in the research 
and development program included testing of prototype antibody products in 
its animal models.  See "Chiron Relationship" below.

MANUFACTURING SYSTEM

     The Company's manufacturing system can be used for producing antibodies 
to be used for both nutritional products and pharmaceuticals and 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 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.

     The Company's processing system is the same for the manufacture of all 
of the Company's pharmaceutical 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.


                                       8
<PAGE>

     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 Company has two patents that have been 
issued for this process.  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 
processing system in compliance with Good Manufacturing Practices for the 
manufacture of biologics.

     The Company has developed additional processes for the manufacture of 
Proventra Brand Natural Immune Components and final product formulations as 
part of its nutritional product development efforts.  The Company has 
obtained Kosher certification for these natural immune components.  
Additionally, the Company has obtained the appropriate license from Minnesota 
Department of Agriculture.

     Construction of the Company's pilot plant facility within the existing 
Land O'Lakes pilot plant complex in Arden Hills, Minnesota was completed in 
1996. The Company does not anticipate that it will need to fully validate the 
facility for pharmaceutical purposes in 1998.*  Land O'Lakes has guaranteed 
the equipment leases associated with the pilot plant facility.  The Company 
believes that the capacity of this facility will be adequate for the 
production of nutritional and pharmaceutical products, either for sale or 
clinical requirements, in 1998 and believes that contract manufacturers would 
be available to increase its production capacity quickly, if required.*

LICENSE AGREEMENTS AND RESEARCH COLLABORATIONS

     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 
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 antibodies, 
vaccine, molecular biology, and processing and manufacturing technology.*  
The Company also may seek collaborative arrangements for commercialization of 
its antibody products.*

     The Company's antibody technology may be applied to the development of 
nutritional and pharmaceutical products in many areas.*  To exploit its core 
technology as broadly as possible in human applications, the Company's 
strategy is to enter into licensing and collaborative relationships with food 
and pharmaceutical companies with complementary product lines.*  The Company 
spent $3.9 million, $5.3 million and $3.7 million for research and 
development in fiscal years 1997, 1996 and 1995, 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 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 human use.

     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 


                                       9
<PAGE>

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 elect to 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 March 1998, the Company and Land O'Lakes signed 
an amended and restated license agreement (the "Restated License") in which 
the Company has significantly broadened its rights to develop and market 
functional foods. Under the Restated License, the Company can use, improve, 
exploit, license or share existing Procor technology, Procor technology 
improvements and new technologies, as defined, in all areas of functional 
foods except under certain "reserved food product" and "first refusal food 
product" categories, as defined.  If the Company intends to engage in 
manufacturing or marketing any "first refusal food product", the Company must 
give Land O'Lakes notice of its intent, in which case Land O'Lakes can 
negotiate with the Company, in good faith and within a defined period of 
time, to undertake any part of the manufacturing or marketing areas.  If the 
Company intends to engage in manufacturing or marketing any "reserved food 
product", the Company must give Land O'Lakes notice of its intent and must 
only work with Land O'Lakes to undertake the manufacturing or marketing of 
such 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.

     In March 1997, Land O'Lakes granted the Company a license (the "Kefir 
License") to use existing antibody technology and future improvements in the 
development, formulation, manufacture, marketing, distribution and sale of 
kefir-based products, as defined in the Kefir License.  In consideration of 
granting the Kefir License, Land O'Lakes will receive a royalty based on food 
components or ingredients sold by the Company to be included in any 
kefir-based product and on net receipts from any kefir-based finished product 
sold by the Company.  As mentioned below under "Chiron Relationship", Land 
O'Lakes consented to the Company's use of antibody technology for food 
applications of an H. PYLORI product.

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 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.

     Under the agreement, Chiron granted the Company an exclusive worldwide 
license for the use of a proprietary Chiron adjuvant for the production of 
PYLORIMUNE-G. See "Products in Development - Pharmaceuticals - 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 may collaborate 
on the development of antibody products processed from bovine colostrum 
targeting infections caused by H. PYLORI, the bacterium associated with 
ulcers and gastritis.  The research program would, if and when commenced, 
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 


                                       10


<PAGE>

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 
antibody products for veterinary use.  The Company believes that substantial 
barriers exist for competitors desiring to commercialize 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 been issued two patents, #5,670,196 and #5,707,678 from 
the United States Patent & Trademark Office.  The patents cover significant 
processes in its core manufacturing technology for antibodies for 
microfiltering milk and colostrum that reduces bioburden while improving 
yield.  The Company also has two United States patent applications pending 
and has acquired licenses to a number of patents or patent applications of 
others.  The Company's two United States patent applications are in the area 
of 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 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 
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, 


                                       11
<PAGE>

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 is 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

NUTRITIONAL PRODUCTS

     GENERAL

     The formulation, manufacturing, processing, packaging, labeling, 
advertising, distribution and sale of nutritional supplements such as those 
being developed by the Company are subject to regulation by one or more 
federal agencies, principally the FDA and the Federal Trade Commission (the 
"FTC"), and to a lesser extent the Consumer Product Safety Commission and the 
United States Department of Agriculture.  These activities are also regulated 
by various governmental agencies for the states and localities in which the 
Company's products are sold, as well as by governmental agencies in certain 
foreign countries in which the Company's products are sold.  Among other 
matters, regulation of the Company by the FDA and FTC is concerned with 
claims made with respect to a product which refer to the value of the product 
in treating or preventing disease or other adverse health conditions.

     Federal agencies, primarily the FDA and FTC, have a variety of remedies 
and processes available to them, including initiating investigations, issuing 
warning letters and cease and desist orders, requiring corrective labels or 
advertising, requiring consumer redress (for example, requiring that a 
company offer to repurchase products previously sold to consumers), seeking 
injunctive relief or product seizure and imposing civil penalties or 
commencing criminal prosecution.  In addition, certain state agencies have 
similar authority, as well as the authority to prohibit or restrict the 
manufacture or sale of products within their jurisdiction. These federal and 
state agencies have in the past used these remedies in regulating 
participants in the nutritional products industry, including the imposition 
by federal agencies of civil penalties in the millions of dollars against a 
few industry participants.  There can be no assurance that the regulatory 
environment in which the Company operates will not change or that such 
regulatory environment, or any specific action taken against the Company, 
will not result in a material adverse effect on the Company's business, 
financial condition or results of operations.*  In addition, increased sales 
and publicity of nutritional supplements may result in increased regulatory 
scrutiny of the nutritional supplements industry.

     DIETARY SUPPLEMENT HEALTH AND EDUCATION ACT

     DSHEA was enacted in October 1994, amending the Food, Drug and Cosmetic 
Act.  The Company believes this law is generally favorable to the dietary 
supplement industry.*  DSHEA establishes a new statutory class of "dietary 
supplements," which includes vitamins, minerals, herbs, amino acids and other 
nutritional supplements for human use to supplement the diet and includes in 
such class all dietary ingredients on the market as of October 15, 1994.  
Such class of nutritional supplements will not require the submission by the 
manufacturer or distributor of evidence of a history of use or other evidence 
of safety establishing that the supplement will reasonably be expected to be 
safe, but a nutritional supplement which contains a dietary ingredient which 
was not on the market as of October 15, 1994 does require such submission of 
evidence of a history of use or other evidence of safety. Among other things, 
this law prevents the further regulation of dietary ingredients as "food 
additives" and allows the use of statements of nutritional support on product 
labels.


                                       12

PHARMACEUTICAL PRODUCTS

     GENERAL

     The Company's pharmaceutical 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 Product Licensing Applications ("PLA"), 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 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 


                                       13
<PAGE>


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.

     PRODUCT LICENSING APPLICATION

     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 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 pharmaceutical products.  
Consequently, the commencement of manufacturing and marketing of its 
pharmaceutical products is, in all likelihood, at least two to three years 
away.*  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, 


                                       14
<PAGE>

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.

     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

NUTRITIONAL PRODUCTS

     The nutritional products area is highly competitive with many large 
nationally known manufacturers and many smaller manufacturers and marketers 
of nutritional products.  The Company knows of no other company that is 
developing or marketing a product that incorporates antibody technology 
combined with active cultures and other ingredients.  Potential competitors, 
however, could be larger than the Company, have greater access to capital and 
may be better able to withstand volatile market conditions.  Moreover, 
because the nutritional products industry generally has low barriers to 
entry, additional competitors could enter the market at any time.  In that 
regard, although the nutritional products industry to date has been 
characterized by many relatively small participants, national or 
international companies (which may include pharmaceutical companies or other 
suppliers to mass merchandisers) may seek to enter or to increase their 
presence in this industry, which would have a material adverse effect on the 
Company's competitive position.

     The Company has assessed the factors that may make it competitive in 
this environment and believes that its central strength is that its products 
will be unique and distinct in the marketplace by offering direct immune 
enhancing benefits that are currently not offered by a single product.*  
Other nutritional or dietary supplement products, such as vitamins and herbs, 
may help the immune system to function better, but they do not provide 
specific immune protection against common pathogens.*  The Company believes 
that its nutritional beverages will further be distinguished by the fact that 
they are fresh, refrigerated products that contain active cultures and 
antibodies while maintaining a superior taste to other nutritional beverages.*

PHARMACEUTICAL PRODUCTS

     The human pharmaceutical and biotechnology industries are subject to 
intense competition as well as rapid and significant technological change. 
The Company 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.


                                       15
<PAGE>

     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 certain diseases; 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 forming a strategic alliance to commercialize 
its products, it may be required to compete with respect to manufacturing 
efficiency, an area 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 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, 1997, the Company had 17 employees, three of whom have 
Ph.D. degrees and two of whom have M.D. degrees (one of which also has a 
Ph.D. degree).  Nine employees are currently working in research and 
development and three 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.

GENERAL

     The Company's ability to satisfy its anticipated cash requirements 
through approximately the first quarter of 1999 for its working capital and 
capital requirements will depend upon numerous factors, including the 
progress of the Company's research and development programs, clinical trials, 
the timing and cost of obtaining regulatory approvals, marketing activities 
and its ability to secure strategic alliances.  The Company's capital 
requirements also will depend on the levels of resources devoted to the 
development of manufacturing capabilities, technological advances, the status 
of competitive products and the ability of the Company to establish strategic 
alliances to provide funding for research, development and marketing.  The 


                                       16
<PAGE>

Company's ability to continue funding its planned operations beyond the first 
quarter of 1999 is dependent upon its ability to obtain additional funds 
through product revenues, 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 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 significant 
dilution of the Company's current stockholders.

     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 functional food products, no such discussions are 
currently underway.  The Company intends to form additional strategic 
alliances that will leverage its technology to bring products to market, 
including alliances for marketing, manufacturing and distribution for all of 
its products.  There are no assurances, however, that the Company will be 
able to form such strategic alliances.  Without such alliances, the Company 
may not have the financial resources necessary to continue the development of 
certain, if not all, nutritional and pharmaceutical products.

NUTRITIONAL PRODUCTS

     The Company, like any manufacturer of products that are designed to be 
ingested, faces an inherent risk of exposure to product liability claims in 
the event that the use of its products results in injury.  In the event that 
the Company does not have adequate insurance or contractual indemnification, 
product liability claims could have a material adverse effect on the Company. 
The Company is not currently a named defendant in any product liability 
lawsuit. The successful assertion or settlement of any uninsured claim, a 
significant number of insured claims, or a claim exceeding the Company's 
insurance coverage could have a material adverse effect on the Company.

     The Company will be highly dependent upon consumers' perception of the 
safety and quality of its products as well as similar products distributed by 
other companies.  Thus, the mere publication of reports asserting that such 
products may be harmful could have a material adverse effect on the Company, 
regardless of whether such reports are scientifically supported and 
regardless of whether the harmful effects would be present at the dosages 
recommended for such products.

     Although the ingredients in the Company's products have a long history 
of human consumption, some of the Company's products may contain innovative 
ingredients or combinations of ingredients.  Although the Company believes 
all of its potential products will be safe when taken as directed by the 
Company, there is little long-term experience with human consumption of 
certain of these innovative product ingredients or combinations thereof in 
concentrated form. Although the Company performs research and/or tests the 
formulation and production of its products, it will sponsor only limited 
clinical studies or rely on other outside published data. 

     The nutritional products area is highly competitive with many large 
nationally known manufacturers and many smaller manufacturers and marketers 
of nutritional products.  The Company currently knows of no other company 
that is developing or marketing a product that incorporates antibody 
technology combined with active cultures and other ingredients.  Potential 
competitors, however, could be larger than the Company, have greater access 
to capital and may be better able to withstand volatile market conditions.  
Moreover, because the nutritional products industry generally has low 
barriers to entry, additional competitors could enter the market at any time. 
In that regard, although the nutritional products industry to date has been 
characterized by many relatively small participants, there can be no 
assurance that national or international companies (which may include 
pharmaceutical companies or other suppliers to mass merchandisers) will not 
seek to enter or to increase 


                                       17
<PAGE>

their presence in this industry.  Increased competition in the industry could 
have a material adverse effect on the Company.

     Market and related data (including, without limitation, information as 
to the dollar amount of retail sales for the nutritional beverage market) 
were obtained from Frost & Sullivan, a competitive-market analysis firm.  The 
Company has not independently verified the accuracy of such information, and, 
in any event, the methodology typically used in compiling market and related 
data means that such data is subject to inherent uncertainties and 
estimations.  As a result, there can be no assurance as to the accuracy or 
completeness of the market and other similar information (including 
information as to sales) appearing in this Annual Report on Form 10-K.

     The Company believes that its pilot plant will meet the anticipated 
requirements for the production of nutritional products and believes that 
contract manufacturers would be available to increase its production capacity 
quickly, if required.  However, given the limited manufacturing experience of 
the Company in nutritional products, no assurance can be given that the 
Company will be successful in producing acceptable product on a commercial 
scale and at acceptable costs in its pilot plant facility.  The Company's 
nutritional products will be regulated by MDA under the appropriate license.

PHARMACEUTICAL PRODUCTS

     Diffistat-G will require additional research and development and further 
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, or that a partner will be found with adequate resources to 
fund further clinical testing or research and development if needed. Time 
required for completion of trials may be affected by the rate at which 
patients meeting trial criteria can be found and enrolled. 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.

     The Company believes that certain of its products in development may 
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 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.

     The Company believes that its pilot plant will meet the anticipated 
requirements for the production of pharmaceutical products, either for sale 
or clinical requirements, in 1998 and believes that contract manufacturers 
would be available to increase its production capacity quickly, if required. 
The Company does not 


                                       18
<PAGE>

anticipate that it will need to fully validate the facility for 
pharmaceutical purposes in 1998. To successfully establish commercial 
pharmaceutical manufacturing capacity, the Company will have to scale up its 
manufacturing processes and demonstrate the ability to consistently 
manufacture a clinically safe pharmaceutical product. Given the limited 
manufacturing experience of the Company in  pharmaceutical products, no 
assurance can be given that the Company will be successful in producing 
acceptable product on a commercial scale and at acceptable costs in its pilot 
plant facility.  The Company's pharmaceutical products will be regulated by 
FDA as human biologics, respectively, and its manufacturing facility may have 
to be operational prior to its potential partner completing required  pivotal 
clinical trials.

     The human pharmaceutical and biotechnology industries are subject to 
intense competition as well as rapid and significant technological change.  
The Company expects that the human pharmaceutical and biotechnology 
industries will continue to experience rapid technological development which 
may render the Company's processes and products noncompetitive or obsolete.  
GalaGen is also aware of companies which are developing products that will 
compete for the same disease markets as several of the Company's products.  
Many of these competitors, or potential 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 GalaGen is developing.

ITEM 2.   PROPERTIES

     The Company leases approximately 4,500 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 antibody products for development, early stage clinical use 
and potential commercial use.  At the end of 1996, the Company completed its 
pilot plant.   Management believes that the Company's facilities are suitable 
and adequate for current office, research and manufacturing requirements.

have the right for a subsequent ninety (90) day period to conclude its 
proposed grant of distribution or marketing rights to the third party on the 
terms stated in its notice to Land O'Lakes, free and clear of Land O'Lakes 
right of first refusal.  If such grant is not completed within such

of this Agreement, Licensor shall deliver to Licensee:

Collaborator (as determined from Schedule A hereto as amended from time to 
time).

     7.   REPRESENTATIONS, WARRANTIES AND COVENANTS.  Licensor hereby

          effect of its doing so may be to diminish, encumber or impair the

     (c)  Land O'Lakes shall not directly or indirectly, prior to the 
fifteenth anniversary of the date of this Agreement, anywhere in the world

     (d)  Licensor shall not directly or indirectly, without providing Land
O'Lakes with those rights of first refusal and participation provided in Section

include third parties, conducted as part of normal business development 
activities or (ii) Licensor's ability to purchase ingredients or other 
supplies from any supplier.

     11.  RIGHTS OF FIRST REFUSAL AND PARTICIPATION.  (a) If Licensor intends 
to collaborate with any other person or entity in manufacturing or marketing 
any First Refusal Food Product, then Licensor shall give written notice to 
Land O'Lakes prior to entering into any definitive agreement relating 
thereto.  Such notice shall state the material terms of the proposed 
activities, such as a description of the proposed manufacturing, distribution 
or marketing activities to be undertaken, the costs or obligations proposed 
to be borne by each party, any quotas or minimums, pricing, commissions or 
other compensation, customer or prospect restrictions or requirements, 
specifications and quality parameters, and territories.  Upon receipt of 
Licensor's written notice, Land O'Lakes shall have a right of first refusal 
for a period of thirty (30) days to enter into an agreement with Licensor to 
undertake the manufacturing, distribution and marketing activities described 
in Licensor's notice on the same terms as described in such notice.  Land 
O'Lakes shall also have the right during such thirty (30) day period to 
negotiate in good faith its undertaking any part of the activities described 
in such notice if and to the extent that (i) Land O'Lakes is qualified to 
perform such activities as well or better than the other parties specified in 
the notice, consistent with the specifications and quality parameters 
required by the other participants and by applicable legal regulations and

commercially reasonable and which are no less favorable than would be 
negotiated between unrelated parties in an arm's-length transaction.  If 
within such thirty (30) day period Land O'Lakes does not exercise such rights 
of first refusal or participation, then Licensor shall have the right for a 
subsequent ninety (90) day period to conclude its proposed agreement relating 
to the activities described in its notice to Land O'Lakes on substantially 
the terms stated in such notice and thereafter to engage in such activities 
without any time limit, free and clear of Land O'Lakes rights of first 
refusal and participation.  If such grant is not completed within such 
subsequent ninety (90) day period, then Land O'Lakes rights of first refusal 
and participation shall again come into effect.  

                                      -5-

          (b)  If Licensor intends to directly engage in manufacturing or 
marketing any First Refusal Food Product (as opposed to collaborating with 
any other person or entity, which is covered by Section 11(a) above), then 
Licensor shall give written notice to Land O'Lakes prior to commencing such 
manufacturing or marketing.  Such notice shall describe in reasonable detail 
the proposed activities.  Upon receipt of Licensor's written notice, Licensor 
and Land O'Lakes shall negotiate in good faith for a period of sixty (60) 
days to have Land O'Lakes undertake any part of the activities described in 
such notice if and to the extent that (i) Land O'Lakes desires to and is 
qualified to perform such activities consistent with the specifications and 
quality parameters required by the proposed activities and by applicable 
legal regulations and (ii) Land O'Lakes agrees to perform such activities on 
terms which are no less favorable than would be negotiated between unrelated 
parties in an arms's-length transaction.  If Licensor negotiates with Land 
O'Lakes in good faith during such sixty (60) day period, then except to the 
extent Licensor and Land O'Lakes agree on Land O'Lakes' participation in the 
proposed activities, Licensor shall have the right to proceed with the 
activities described in its notice to Land O'Lakes on substantially the terms 
stated in such notice and thereafter to engage, without collaborating with 
any other person or entity, in such activities without any time limit, free 
and clear of any obligation to negotiate with Land O'Lakes regarding Land 
O'Lakes' participation in such activities.

     12.  NO WAIVER.  No delay or failure by either party to enforce any 
right or claim which it may have hereunder shall constitute a waiver of such 
right or claim.  Any waiver by a party of any term, provision or condition 
hereof or of any default hereunder shall be deemed to be a further or 
continuing waiver of such term, provision or condition or of any subsequent 
default hereunder.  

     13.  NOTICES.  Any notices required hereunder shall be given in writing 
and addressed, if to Land O'Lakes, at 4001 Lexington Avenue North, Arden 
Hills, Minnesota  55440, attention:  President, and if to Purchaser, at 4001 
Lexington Avenue North, Arden Hills, Minnesota  55440, Attention:  President,

     14.  HEADINGS.  The headings in this Agreement are for convenience of 
reference only and do not form a part hereof and in no way interpret or 
construe this Agreement.  

     15.  INTEGRATION; MODIFICATIONS.  This Agreement constitutes the entire 
agreement between the parties hereto with respect to the transactions 
contemplated hereby, superseding any other understandings or agreements, oral 
or written, with respect thereof.  By amending and restating this Agreement, 
the parties do not intend to and shall not be deemed to have in any way 
limited the scope of the waiver and consent provided by that letter agreement 
between Land O'Lakes and Licensor dated March 6, 1997 regarding Licensor's 
collaboration with Lifeway Foods, Inc.  This Agreement shall be amended or 
modified only by a written instrument signed by the parties hereto.  

                                      -6-
<PAGE>

     16.  SEVERABILITY.  If any term of this Agreement shall be deemed 
illegal or unenforceable, the other terms hereof shall not be affected 
thereby and shall continue in full force and effect.  

     17.  BINDING EFFECT AND GOVERNING LAW.  This Agreement shall be binding 
upon and inure to the benefit of the successors and assigns of the respective 
parties thereto.  This Agreement shall be governed by and construed in 
accordance with the laws of the State of Minnesota.  

     18.  ARBITRATION.  (a) All disputes, controversies or claims arising out 
of or related to the interpretation or enforcement of this Agreement or any 
alleged breach, termination or claim of invalidity of this Agreement shall be 
settled finally and without resort to any legal proceedings (except for the 
enforcement of the arbitration award) by arbitration conducted in accordance 
with the provisions of this Section.  

     (b)  Notwithstanding the foregoing, the remedy at law for any breach of 
the provisions of this Section is acknowledged by the parties to be 
inadequate, and an aggrieved party seeking relief or remedies for such a 
breach shall have the right and is hereby granted the privilege, in addition 
to all other remedies at law or in equity, to temporary or permanent 
injunctive relief from any court of competent jurisdiction without the 
necessity of proving actual damage.  

     (c)  In the event of any dispute of the nature described in paragraph 
(a) above (including without limitation any dispute regarding an alleged 
breach or non-compliance, or whether a breach or non-compliance has been 
cured or cured within the specified period time, or any other aspect of a 
breach or cure and the dispute arises under or is related to this Agreement) 
either party may submit the dispute to arbitration by delivering a request 
for arbitration pursuant to paragraph (d) below.  The arbitrator shall be 
empowered to require appropriate remedies including, but not limited to, 
termination of the obligation to pay amounts otherwise due or any other 
rights or obligations hereunder, or any combination thereof.  The arbitrator 
shall not terminate obligations or rights under this Agreement on the basis 
of non-material breaches or unintentional breaches.  Neither party shall have 
the right to terminate this Agreement or any portion hereof, except insofar 
as such termination is effected by arbitration according to the above 
guidelines.  All arbitration proceedings shall be held in St. Paul, Minnesota 
in accordance with paragraph (d) below. Judgment upon the award rendered by 
the arbitrator may be entered in any court having jurisdiction thereof.  
Pending final resolution of the dispute, the parties shall continue to 
observe the limitations imposed by this Agreement and shall continue to make 
payment for amounts due in accordance with the provisions of this Agreement.  

     (d)  If any matter is submitted to arbitration pursuant to this 
Agreement, the following procedures will be followed:  

                                      -7-
<PAGE>

         (i)  Either party may initiate arbitration proceedings by delivering 
     a written request for arbitration to the other party stating with 
     specificity the nature of the dispute or disputes to be arbitrated.  

         (ii) Arbitration proceedings will be conducted by one arbitrator who 
     will be chosen by mutual agreement of the parties.  If the parties are 
     unable to agree upon a single arbitrator within ten business days after 
     receipt of the request for arbitration, then the arbitration proceedings 
     will be conducted by three arbitrators, one chosen by each of the 
     parties and the third chosen by the first two arbitrators.  Each party 
     will notify the other party, in writing, of the name and address of its 
     arbitrator within 25 business days after receipt of the request for 
     arbitration.  Any party failing to give such written notice will forfeit 
     the right to name an arbitrator, and the second arbitrator will be 
     selected by the American Arbitration Association (AAA) in accordance 
     with the Commercial Arbitration Rules then in effect.  The two 
     arbitrators so selected will choose a third.  Unless otherwise agreed by 
     the parties, no arbitrator will be an employee, officer, director, 
     counsel, shareholder or consultant for any party to this Agreement.  

         (iii) Each arbitrator will be paid a reasonable fee for his or her 
     services and will be reimbursed for reasonable and necessary expenses 
     upon submission of receipts therefor.  The fees and expenses of the 
     arbitrator(s), as well as all other out-of-pocket costs of arbitration 
     required under the terms of this provision, will be shared equally by 
     the parties.  Costs resulting from requests not required by this 
     provision will be borne by the party making the request.  

         (iv) Discovery will be conducted in accordance with the Federal 
     Rules of Civil Procedure, except as otherwise agreed by the parties or 
     as ordered by the arbitrator(s).  The arbitrator(s) will determine a 
     discovery schedule which the parties will comply.  

         (v)  Unless otherwise agreed by the parties and the arbitrator(s), 
     the arbitrator(s) will fix the date and specific location of the 
     arbitration hearing and give the parties at least 30 days' advance 
     notice of the date and location. The hearing will proceed in general in 
     the manner of a non-jury trial under the Federal Rules of Civil 
     Procedure and the arbitrator shall apply the Federal Rules of Evidence.  
     The arbitrator(s) will entertain such presentation of sworn testimony 
     and other evidence, written briefs, and/or oral argument as the parties 
     may wish to present; however, no testimony or exhibits will be 
     admissible unless the adverse party was afforded an opportunity to 
     examine such witnesses and to inspect and copy such exhibits during the 
     pre-hearing discovery phase.  Any party may be represented by counsel at 
     the hearing.  A qualified court reporter will record and transcribe the 
     proceeding.  The arbitrator(s) will apply the substantive law of the 
     State of Minnesota.  

                                      -8-

         (vi) Upon request of either party, the arbitrator(s) will provide 
     both parties with written findings of fact and conclusions of law.  

         (vii) The decision of the arbitrator(s) will be in writing and will 
     be signed by a majority of the arbitrators.  The decision of the 
     arbitrator(s) shall be binding.  If the parties settle their dispute 
     during the course of the arbitration, the arbitrator(s) will set forth 
     the terms of the agreed settlement in an award.  Such an award may be 
     referred to as a consent award. 
 

         (viii) Any matters not controlled by this provision will be 
     controlled by the Commercial Arbitration Rules of the AAA in effect at 
     the time of the arbitration hearing.  

     IN WITNESS WHEREOF, this Amended and Restated License Agreement has been 
executed by the parties hereto as of March 11, 1998.

          MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
                            AND RESULTS OF OPERATIONS


FORWARD-LOOKING STATEMENTS

     The information presented in this Annual Report to Stockholders for the 
year ended December 31, 1997 (the "Annual Report") contains forward-looking 
statements within the meaning of the safe harbor provisions of Section 21E of 
the Securities Exchange Act of 1934, as amended (the "Exchange Act").  Such 
statements are subject to risks and uncertainties, including those discussed 
below under "Disclosure Regarding Forward-Looking Statements" and in the 
Company's Annual Report on Form 10-K for the year ended December 31, 1997 
("Form 10-K") under "Risk Factors", that could cause actual results to differ 
materially from those projected.  Because actual results may differ, readers 
are cautioned not to place undue reliance on these forward-looking statements.

GENERAL

     GalaGen has broadened its focus to include nutritional products and is 
utilizing its expertise in its platform antibody technology to develop a 
portfolio of proprietary nutritional products, including dietary supplements, 
which incorporate its Proventra-TM- Brand Natural Immune Components.  These 
products will target needs of both consumers and healthcare professionals. 
GalaGen continues to develop oral pharmaceuticals that target life 
threatening and emerging pathogens. These antibodies used in nutritional and 
pharmaceutical products are food proteins that are derived from the milk 
collected in the first few milkings of a dairy cow after its calf is born.  
Using its proprietary procedures, the Company has produced antibodies that 
target specific pathogens infecting the human gastrointestinal tract, 
including bacteria and their toxins, parasites, fungi and viruses.  Because 
the Company's antibodies 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.  

     In August 1997, the Company announced that it was placing its Sporidin-G 
clinical trial on hold due to continuing decline in the patient population 
for the product's initial indication, AIDS-related CRYPTOSPORIDIUM PARVUM 
infection.  The decline was brought about by the effectiveness and increased 
use of new AIDS therapies, including protease inhibitors and earlier 
administration of combination therapy.

     In December 1997, the Company introduced Basics Plus, a dietary 
supplement product, in conjunction with its marketing and manufacturing 
partner, Lifeway Foods.  Basics Plus is the first product to emerge from the 
collaboration with Lifeway Foods and contains active beneficial kefir 
cultures and GalaGen's Proventra-TM- Brand Natural Immune Components.

     Diffistat-G, its pharmaceutical product in Phase II clinical 
development, is being developed for the treatment and prevention of 
antibiotic-associated diarrhea, a disease which annually affects more than 
400,000 patients in the United States.

RESULTS OF OPERATIONS

YEARS ENDED DECEMBER 31, 1997, 1996 AND 1995

     GENERAL.  The net loss applicable to common stockholders decreased by 
$9,148,457, or 61.9%, in 1997 to $5,635,134 from $14,783,591 in 1996 and 
increased by $9,309,553, or 170.1%, in 1996 from $5,474,038 in 1995. The 
decrease in 1997 and 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 Company's initial public offering (the 
"Offering"), which occurred in April 1996.  Historical spending levels 


                                       1
<PAGE>

may not be indicative of future spending levels.  The Company is continuing 
its nutritional and pharmaceutical product development activity, which is 
planned to include costs relating to research and development activity, 
small-scale manufacturing, clinical trial activity and market research. 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 
decreased $1,321,803, or 25.1%, in 1997 to $3,935,817 from $5,257,620 in 1996 
and increased $1,526,543, or 40.9%, in 1996 from $3,731,077 in 1995. The 
decrease in 1997 was due primarily to decreased clinical trial expenses 
associated with Sporidin-G of approximately $2,000,000 and decreased 
personnel and administration expenses of approximately $280,000 offset 
primarily by increased manufacturing expenses of approximately $440,000, 
increased clinical expenses for Diffistat-G of approximately $320,000 and 
increased nutritional products expense of approximately $200,000.  The 
increase in 1996 as compared to 1995 was due primarily to increased expenses 
associated with the Sporidin-G clinical trial as well as increased 
development, clinical and personnel expenses for the Company's other 
products, offset by a $300,000 license fee paid to Chiron Corporation in 1995 
in the form of Company stock.

     GENERAL AND ADMINISTRATIVE EXPENSES.  General and administrative 
expenses increased $76,642 or 4.1% in 1997 to $1,966,001 from $1,889,359 in 
1996 and decreased $132,840, or 6.6%, in 1996 from $2,022,199 in 1995. The 
increase in 1997 is due primarily to increased public reporting and 
shareholder relations expense of approximately $157,000 and increased 
insurance costs of approximately $68,000 offset by decreased outside 
consulting expense of approximately $83,000 and decreased deferred 
compensation expense of approximately $65,000. The decrease in 1996 compared 
to 1995 was due primarily to a decrease of $136,200 in deferred compensation 
expense (see Note 9 of Notes to Financial Statements).

     INTEREST INCOME.  Interest income was $448,322 in 1997, $605,548 in 1996 
and  $30,526 in 1995. The decrease in 1997 is attributable to the decreased 
level of investable funds.  The increase from 1995 to 1996 was due to the 
investment of funds received by the Company from the Offering.

     INTEREST EXPENSE.  Interest expense was $181,638 in 1997, $945,316 in 
1996 and $506,709 in 1995. Interest expense for 1997 consisted primarily of 
line of credit interest expense of $91,679 (see Note 7 of Notes to Financial 
Statements) and convertible debt interest expense of $82,459 (see Note 8 of 
Notes to Financial Statements).  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 (the "Convertible Promissory Notes") issued by 
the Company.  The Convertible Promissory Notes converted into Common Stock 
upon the closing of the Offering. Interest expense for 1995 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 (see Note 12 of the Notes to the Financial Statements).

     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 the 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,
1997, investments in the Company have totaled approximately $53.1 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 $28.1 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 decreased by $83,664, or 1.4%, in 1997 
to $6,052,148 from $6,135,812 in 1996 and increased by $2,903,924, or 89.9%, 
in 1996 from $3,231,888 in 1995. Cash used in operations went primarily to 
fund operating losses and was offset slightly by changes in operating assets 
and liabilities.

     The Company invested $13,276 in 1997 and $7,498,343 in 1996 in 
available-for-sale securities.  The Company invested $215,320 in 1997 and 
$1,264,342 in 1996 in equipment and tenant improvements related to the 
Company's pilot plant manufacturing facility, the majority of which has been 
subsequently financed through the line-of-credit (see Note 7 of Notes to the 
Financial Statements). The Company invested $63,685 in 1997, $193,012 in 1996 
and $36,311 in 1995 in lab equipment, computer equipment and software and 
furniture used primarily to support the Company's operations.

     The Company's seven-year operating lease for manufacturing equipment is 
in effect through 2003 and requires future annual minimum payments of 
approximately $140,000.  Additionally the Company's five-year lease agreement 
with Land O'Lakes for specified manufacturing space is in effect through 
June 2001 and requires future annual minimum payments of approximately 
$86,000 (see Note 10 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 1999. The Company's working capital and 
capital requirements will depend upon numerous factors, including the 
progress of the Company's market research, product development and marketing 
and distribution for nutritional products in addition to the clinical trials, 
research and development programs and the timing of and cost of obtaining 
regulatory approvals and marketing activities for pharmaceutical products. 
The Company's capital requirements also will depend on the levels of 
resources devoted to the development of manufacturing capabilities, 
technological advances, the status of competitive products and the ability of 
the Company to establish strategic alliances to provide funding to the 
Company for research, development and marketing.

     The Company expects to incur substantial additional research and 
development and other costs, including costs related to clinical studies and 
marketing activities for both nutritional and pharmaceutical products. 
Capital expenditures may be necessary to obtain licensure of the existing 
pilot plant facility and to establish additional commercial scale 
manufacturing facilities. The Company will need to raise substantial 
additional funds for longer-term product development, manufacturing and 
marketing activities that may be required in the future. The Company's 
ability to continue funding its planned operations beyond the first quarter 
of 1999 is dependent upon its ability to generate product revenues or to 
obtain additional funds through equity or debt financing, strategic 
alliances, license agreements or from other financing sources. A lack of 
adequate revenues or funding could eventually result in the insolvency or 
bankruptcy of the Company. At a minimum, if adequate funds are not available, 
the Company may be required to delay or to eliminate expenditures for certain 


                                       3
<PAGE>

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 
substantial dilution to the Company's current stockholders.

YEAR 2000 ISSUES

     Certain of the Company's business systems may require updating to 
continue to function properly beyond 1999.  The Company believes that it will 
have adequate resources for this purpose and does not expect to incur 
significant expenditures to address this issue.

DISCLOSURE REGARDING FORWARD-LOOKING STATEMENTS

2.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

CASH EQUIVALENTS

     Cash equivalents include short-term highly liquid investments purchased 
at cost, which approximates market, with remaining 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, 1997 and 1996. The book value of the investments approximates 
their estimated market value.  The estimated market value of investments by 
security type as of December 31, 1997 and 1996 is as follows:

primarily on a straight-line basis over their estimated useful lives of three 
to seven years.

     At December 31, 1996, construction in progress consisted of leasehold 
improvements and manufacturing equipment in connection with the Company's 
pilot plant manufacturing facility.  The Company transferred the construction 
in progress to its respective asset account and began depreciation in the 
third quarter of 1997.   At December 31, 1997 and 1996, property, plant and 
equipment consisted of the following:

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

     In 1997, the Financial Accounting Standards Board issued Statement No. 
128, EARNINGS PER SHARE ("Statement 128").  Statement 128 replaced the 
calculation of primary and fully diluted earnings per share with basic and 
diluted earnings per share.  Unlike primary earnings per share, basic 
earnings per share excludes any dilutive effects of options, warrants and 
convertible securities.  All earnings per share amounts for all periods have 
been presented, and where appropriate, restated to conform to Statement 128 
requirements.

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.

3.   MERGER

     In March 1992, GalaGen was incorporated as a wholly-owned subsidiary of 
its predecessor, Procor Technologies, Inc.("Procor"), a wholly-owned 
subsidiary of Land O'Lakes Inc. ("Land O'Lakes"), and issued 270 shares of 
its $.01 par value common stock to Procor for $1.23 per share. In May 1992, 
GalaGen sold 941,148 shares of its common stock to certain outside investors 
and future officers, directors, and advisors of GalaGen for $1.23 per share. 
Effective July 24, 1992, GalaGen was merged with Procor and GalaGen was the 
surviving entity. As part of this merger, the 13,541 shares of Procor's 
common stock held by Land O'Lakes were converted into 812,502 shares of $.01 
par value common stock of GalaGen. Additionally, the 270 shares of common 
stock of GalaGen issued to Procor were canceled and $7,127,720 of 
inter-company obligations owed to Land O'Lakes were forgiven and recorded as 
contributed capital.

4.   RELATED PARTY TRANSACTIONS

     During 1992, the Company entered into the following agreements with Land 
O'Lakes:

PURCHASE AND SALE OF ASSETS AGREEMENT

     Land O'Lakes purchased from the Company all equipment, inventory, and 
certain other assets and assumed all current liabilities at book value, which 
approximated $1,636,000. The purchase price was paid by crediting against 
other indebtedness owed by the Company to Land O'Lakes.

ROYALTY AGREEMENT

      The Company will pay to Land O'Lakes a royalty on net receipts from any 
product, other than infant formula, which is based on existing technology or 
technology improvements, as defined by the agreement.  The Company will pay 
an additional royalty on net receipts from infant formula based on existing 
or improved technology and an additional royalty on net receipts from infant 
formula based on new technology, as defined by the agreement.  This agreement 
will continue until terminated by both parties.  Royalty payments range from 
one to two percent of net receipts.

LICENSE AGREEMENT

     The Company has licensed to Land O'Lakes the rights to use the Company's 
existing technologies and technology improvements, as defined by the 
agreement, for Land O'Lakes' use in animal products, functional foods and 
infant formula. The Company received a lump sum license fee. The Company has 
agreed not to compete for fifteen years in the area of animal products and 
functional foods based on milk and colostrum based immunoglobulin technology. 
Land O'Lakes has agreed not to compete for fifteen years in the areas of 
prescription drugs and over-the-counter drugs regulated by the Food and Drug 
Administration. The term of this agreement is perpetual.

     In March 1997, Land O'Lakes granted a five-year license, an amendment to 
the license above, in the area of functional foods to use existing technology 
and future technology improvements in the development, formulation, 
manufacture, marketing, distribution and sale of kefir-based products, as 
defined in the granted license.  In consideration of granting the Company 
this license, Land O'Lakes will receive a royalty of five percent from food 
components or ingredients sold by the Company to be included in a kefir-based 
product and one percent of net receipts from a kefir-based finished product 
sold by the Company.

     In March 1998, the Company and Land O'Lakes signed an amended and restated
license agreement in which the Company has significantly broadened its rights to
develop and market functional foods.   Under the restated license agreement, the
Company can use, improve, exploit, license or share existing technology,
technology improvements and new technologies, as defined, in all areas except
under certain "reserved food" and "first refusal food product" categories.

SUPPLY AGREEMENT

     The Company has entered into an agreement with Land O'Lakes whereby the 
Company will purchase and Land O'Lakes will supply, at their option, all of 
the Company's commercial requirements for colostrum and milk. As part of this 
agreement, Land O'Lakes will provide expertise in dairy herd selection, 
on-farm management, membership relations and procurement to the Company for 
the manufacture of antibody material. The agreement will last for ten years 
and Land O'Lakes, at its sole discretion, has the option to extend the 
agreement for an additional ten years.


                                       16

MASTER SERVICES AGREEMENT

     The Company has entered into an agreement with Land O'Lakes whereby the 
Company may purchase services from Land O'Lakes for certain administrative 
and research and development activities.  This agreement will enable the 
Company to access expertise, on an as-needed basis, from Land O'Lakes.  The 
agreement terminated on December 31, 1992, but has been renewed annually and 
is currently extended through December 31, 1998.  The Company was charged 
approximately $442,000, $682,000 and $641,000 in 1997, 1996 and 1995, 
respectively, in accordance with the Master Services Agreement.

STRATEGIC ALLIANCE LETTER OF INTENT

     The Company and Land O'Lakes have entered into a letter of intent for good
faith discussions designed to lead to a definitive agreement regarding a
strategic alliance to provide research, development, regulatory and product
support, manufacturing, marketing, sales and distribution for certain functional
food products.

PROMISSORY NOTE

     The Company issued a promissory note to Land O'Lakes for $4,000,000 as 
part of the merger. This note had an interest rate of five percent and was 
due December 31, 1992. Payment of $3,000,000 plus accrued interest of $43,333 
was made upon the sale of the Series A preferred stock. Land O'Lakes extended 
the remaining $1,000,000 note for consideration of $100,000. The $1,000,000, 
accrued interest of $50,959 and the $100,000 extension fee were paid in 1993.

     Subsequent to 1992, the Company has entered into other related party 
agreements as noted below:

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

     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 initial public offering (the "Offering").  Loans under this line of 
credit were 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 Land O'Lakes 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 9.

     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 
10.

     In December 1996, the Company entered into an equipment operating lease 
which was guaranteed by Land O'Lakes.  See Note 10.

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).

6.   STOCK

INITIAL PUBLIC OFFERING

     GalaGen Inc. consummated the Offering on April 1, 1996, which consisted 
of 2,000,000 shares of common stock at a $10 per share price to the public.  
All of the Company's preferred stock mandatorily converted into common stock 
immediately prior to the closing of the Offering.  The 2,500,000 shares of 
Series A preferred stock, 1,234,748 shares of Series B preferred stock and 
551,000 shares of Series C preferred stock that were outstanding prior to the 
Offering were converted into 677,063, 543,413 and 248,758 shares of common 
stock, respectively, upon the closing of the Offering. The $8,275,000 of  
Convertible Promissory Notes to investors, plus accrued interest, that were 
outstanding prior to the Offering converted into shares of Series D preferred 
stock and simultaneously into 1,434,495 shares of common stock upon the 
closing of the Offering.  The 338,461 shares of Series E preferred stock and 
34,287 shares of Series F stock outstanding prior to the Offering were 
converted into 178,568 and 85,717 shares, respectively, of common stock upon 
the closing of the Offering.

     The Series D preferred stock, Series E preferred stock and Series F-1 
preferred stock converted into common stock at 70% of the Offering price. 
These reductions in the conversion prices to 70% of the Offering price were 
valued at $7,296,844 and recorded as a non-cash preferred stock dividend to 
arrive at the net loss available to holders of common stock in the 
calculation of net loss per share.

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 calendar year 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 period 
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. In May 1997, the 
Employee Stock Purchase Plan was amended by stockholders to have two six 
month purchase periods beginning on January 1 and July 1 of each year.  In 
1997, 8,279 shares of common stock were purchased of which 5,009 shares were 
issued in 1997.

7.   LINE-OF-CREDIT

     In June 1997, the Company established a $2,000,000 line-of-credit for 
fixed assets with Transamerica Business Credit Corporation ("Transamerica") 
which extends through June 1998. Terms of the line-of-credit 


                                       18
<PAGE>

include monthly payments over four years equal to 2.5837% of each advance 
with a final balloon payment of 12.5% at the end of the four-year period. The 
line-of-credit is secured by the Company's fixed assets. Transamerica 
received a warrant for 40,000 shares of common stock granted at the fair 
market value on the date of grant. The warrant was valued at approximately 
$79,000 and will be amortized to interest expense over the expected term of 
the outstanding line-of-credit. The Company drew approximately $1,319,000 of 
the line-of-credit in 1997, of which $1,162,248 is outstanding at December 
31, 1997.

8.   CONVERTIBLE DEBENTURES

     In November 1997, the Company raised $1,500,000 through the private 
placement sale of 6% convertible debentures (the "Debentures") to three 
institutional investors pursuant to Regulation D under the Securities Act of 
1933.  The principal and interest of the Debentures can be converted into 
shares of the Company's common stock at 82.5% of the lowest closing bid price 
of the Company's common stock three days prior to conversion. One-third of 
the Debentures can convert to common stock upon the effective date of 
registration, one-third after five months from the closing date and the 
remaining one third twelve months after the closing date or nine months if 
the price of the common stock does not average at least $2.00 per share in 
the eighth month after closing.  An aggregate maximum of 1,400,000 discounted 
shares of common stock (the "Discounted Shares") can be issued upon the 
conversion of the Debentures, with each investor owning at any given time a 
maximum of 4.99% of the then issued and outstanding shares of common stock. 
If there remains any unconverted principal and accrued interest due to all 
the Discounted Shares being issued, the Company has the obligation to repay 
the investors, in the aggregate, a maximum principal of $500,000.  The 
Debentures automatically convert into the Discounted Shares eighteen months 
from the closing date.  Five-year warrants were issued to the investors to 
purchase, in the aggregate, 200,000 shares of common stock at 110% of the 
market value of the common stock on the closing date.  The value of the 
warrants plus the value of the discount of the Discounted Shares was 
$500,182, which the Company is amortizing over the term of the Debentures. In 
1997, $72,000 was amortized and recorded as interest expense. A deferred 
expense was recorded for $119,081, which represents costs associated with 
closing the Debentures. These deferred expenses are being amortized until the 
Debentures are converted into Discounted Shares.  In 1997, $9,378 was 
amortized and recorded as an expense.  In February and March 1998, $499,500 
of Debenture principal plus accrued interest was converted into 718,543 
shares of common stock.  The net carrying value of the Debentures 
approximates fair market value.  In connection with this private placement, 
the Company has reserved 1,129,062 shares of common stock for issuance.

9.   OPTIONS AND WARRANTS

STOCK OPTION PLAN

     The Company has established a 1992 Stock Plan (the "1992 Plan") and a 
1997 Incentive Plan (the "1997 Plan"), under which both incentive and 
non-qualified options may be granted, which have reserved 880,210 and  
1,250,000 shares of common stock, respectively, for issuance.  The Company 
uses these plans as an incentive for employees, directors and technical 
advisors.  Stock awards in the aggregate of 100,000 shares of common stock 
may also be granted under the 1997 Plan. Options are granted at fair market 
value as determined on the date of grant and normally vest over three to five 
years.

common stock in exchange for services provided.

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.


                                       20
<PAGE>

     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 June 1994 to October 1995 Convertible Promissory 
Notes (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, 1997, 3,117,672 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, 1997 of $1.93 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 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.

     In March 1997, the Company issued warrants to purchase 10,000 shares of 
common stock, granted at the fair market value on the date of grant, for 
certain services to be rendered.  The warrant expires in March 2002.

     In connection with the line-of-credit, Transamerica received a five-year 
warrant for 40,000 shares of common stock granted at the fair market value on 
the date of grant. The intrinsic value of the warrant is approximately 
$79,000 and is being amortized to interest expense over the expected term of 
the outstanding line-of-credit.  See Note 7.

     In conjunction with the issuance of the Debentures, the Company issued 
warrants to purchase 200,000 shares of the Company's common stock at 110% of 
the market value of the common stock on the closing date of the Debentures.  
The intrinsic value of these warrants is $182,000, which is being amortized 
as interest expense.  These warrants expire in December 2002.  See Note 8.

     In December 1997, the Company issued five-year warrants to financial 
consultants to purchase 25,000,  40,000 and 75,000 shares of common stock at 
$2.50, $3.00 and $6.50, respectively, which was greater than the market value 
of the common stock at the date of grant.  These warrants have an intrinsic 
value of $50,450 which is being amortized over the term of the consulting 
relationship.  The warrant for 75,000 shares of common stock will vest upon 
the Company's common stock trading for ten consecutive days, from the time of 
grant until June 30, 1998, at or greater than $6.50 per share.

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 1997, 1996 and 1995: risk-free interest rates approximating 
6.2%; volatility factor of the expected market price of the Company's common 
stock ranging from .3 to .527 and a weighted-average expected life of the 
option of 5 years. The weighted average fair value of the options granted in 
1997 and 1996 is $2.16 and $2.54 per share, respectively, as computed as 
described above.

     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


                                      22
<PAGE>

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:

The pro forma effect on net loss for 1997, 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 affected.  In December 1997 and 1996, the Company 
adjusted the deferred compensation balance by $35,800 and $261,200 to account 
for terminated employee options that were not vested. The deferred 
compensation is amortized ratably over the vesting period of the options.  In 
1997, 1996 and 1995, $273,864, $340,066 and $476,266 was amortized, 
respectively.

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

10.  COMMITMENTS

     The Company has commitments under the following agreements:

LICENSE AGREEMENTS

     In March 1993, Nestec, an affiliate of Nestle' Ltd., granted a license 
to the Company, including the right to grant sublicenses, relating to the 
production and use of bovine anti-rotavirus and anti-E. Coli antibodies 
derived from milk and colostrum for therapeutic and prophylactic 
applications. The license is exclusive in North America and semi-exclusive in 
the rest of the world and obligates the Company to pay royalties on products 
incorporating the licensed technology.


                                      23
<PAGE>

     In September 1993, Institut Pasteur granted the Company an exclusive 
worldwide license to certain applications relating to human passive immunity. 
Conversely, the Company granted Institut Pasteur an exclusive worldwide 
license relating to certain technology regarding active immunity. Both 
license agreements expire upon the earlier of ten years from the date of the 
first commercial sale arising out of the use of these certain technologies or 
upon the expiration of the last to issue licensed patent on a 
country-by-country basis.

     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 9.

     In November 1997, the Company entered into a product development 
agreement with Taste Technologies, Inc. to collaborate on the creation of 
nutritional products containing GalaGen antibodies.  Based upon their 
contributions Taste Technologies is entitled to receive royalties on certain 
net sales.

     The royalties on the above agreements range from one-half to five 
percent, depending on the volume, of certain net sales.

OTHER AGREEMENTS

     A three-year service agreement that began in 1996 for specified raw 
material preparation assistance requires minimum payments of approximately 
$24,000 in 1998 and $14,000 in 1999.

     The Company entered into a clinical service agreement with a contract 
research organization in June 1997. This agreement requires payment over the 
length of the clinical trial that is anticipated to be completed in 1998.  
The agreement requires a minimum payment of approximately $36,000 in 1998.

LEASE COMMITMENTS

     The Company leases certain office equipment under an operating lease.

     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.


                                      24
<PAGE>

     The total lease expense was $199,808, $3,133 and $9,547, respectively, 
for the years ended December 31, 1997, 1996, and 1995. The future minimum 
annual lease payments are as follows:

11.  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, 1997, GalaGen has 
operating loss carryforwards to offset future taxable income of approximately 
$33,500,000 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.

     Components of deferred tax assets are as follows:

12.   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 
negotiated debt reduction settlements with certain research collaborators and 
a vendor in the aggregate amount of $605,421.  The effect on the December 31, 
1995 net loss per share was $.32 for basic and diluted net loss per share.

                         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, 1997, and 1996, and the related 
statements of operations, changes in stockholders' equity and cash flows for 
each of the three years in the period ended December 31, 1997, and for the 
period from November 17, 1987, (inception) to December 31, 1997. 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, 1997 and 1996 and the results of its operations and cash flows 
for each of the three years in the period ended December 31, 1997 and for the 
period from November 17, 1987, (inception) to December 31, 1997, in 
conformity with generally accepted accounting principles.

RECENT SALES OF UNREGISTERED SECURITIES

          During the year ended December 31, 1997, the Company has sold the 
following equity securities pursuant to exemptions from registration under 
the Securities Act of 1933, as amended (the "Securities Act").  All such 
sales were made in reliance upon the exemptions from registration provided 
under Sections 3(b) and 4(2) of the Securities Act.

          1.   In March 1997, the Company issued warrants to purchase 10,000 
shares of Common Stock, granted at the fair market value on the date of 
grant, for certain investor relations services to be rendered by CTC, Inc.  
The warrant is exercisable one year from the date of grant and expires in 
March 2002.

          2.   In June 1997, the Company established a $2,000,000 line of 
credit with Transamerica Business Credit Corporation ("Transamerica") which 
extends through June 1998.  In connection with this transaction, Transamerica 
received a warrant for 40,000 shares of Common Stock granted at the fair 
market value on the date of grant.  The warrant was valued at approximately 
$79,000 and will be amortized to interest expense over the expected term of 
the outstanding line of credit. The warrant is immediately exerciseable and 
expires in June 2002.  

          3.   In November 1997, the Company raised $1,500,000 through the 
private placement sale of 6% convertible debentures (the "Debentures") to CPR 
(USA) INC., Libertyview Plus Fund and Libertyview Fund, LLC, all 
institutional investors.  The Malachi Group, Inc. acted as an agent in this 
transaction  The principal and interest of the Debentures can be converted 
into shares of the Company's Common Stock at 82.5% of the lowest closing bid 
price of the Company's Common Stock three days prior to conversion.  
One-third of the Debentures can convert to Common Stock upon the effective 
date of registration, one-third after five months from the closing date and 
the remaining one third twelve months after the closing date or nine months 
if the price of the Common Stock does not average at least $2.00 per share in 
the eighth month after closing.  An aggregate maximum of 1,400,000 discounted 
shares of Common Stock  (the "Discounted Shares") can be issued upon the 
conversion of the Debentures, with each investor owning at any given time a 
maximum of 4.99% of the then issued and outstanding shares of Common Stock.  
If there remains any unconverted principal and accrued interest due to all 
the Discounted Shares being issued, the Company has the obligation to repay 
the investors, in the aggregate, a maximum principal of $500,000.  The 
Debentures automatically convert into the Discounted Shares eighteen months 
from the closing date.  Five-year warrants were issued to the investors to 
purchase, in the aggregate, 200,000 shares of Common Stock at 110% of the 
market value of the Common Stock on the closing date.  The value of the 
warrants plus the value of the discount of the Discounted Shares was 
$500,182, which the Company is amortizing over the term of the Debentures.  
In February and March 1998, $499,500 of Debenture principal plus accrued 
interest was converted into 718,543 shares of Common Stock.  In connection 
with this private placement, the Company has reserved 1,129,062 shares 
of Common Stock for issuance.  These warrants expire in December 2002.

          4.   In December 1997, the Company issued five-year warrants to 
CLARCO Holdings, which is associated with the Malachi Group, Inc., for 
financial services rendered, to purchase 25,000, 40,000 and 75,000 shares of 
Common Stock at $2.50, $3.00 and $6.50, respectively, each of which was 
greater than the market value of the Common Stock at the date of grant.  A 
portion of the warrant for 40,000 shares was issued as partial payment for 
services rendered in connection with the private placement of the Debentures. 
These warrants have an intrinsic value of $50,450 which is being amortized 
over the term of the consulting relationship.  The warrants for 25,000 and 
40,000 shares of Common Stock are immediately exercisable.  The warrant for 
75,000 shares of Common Stock will vest upon the Company's Common Stock 
trading for ten consecutive days, from the time of grant until June 30, 1998, 
at or greater than $6.50 per share.  These warrants expire in December 2002.
