Item 1. BUSINESS
 
OVERVIEW

     Genome Therapeutics Corp. ("GTC" or the "Company") is a leader in the field
of genomics -- the identification and characterization of genes. The Company has
over ten years of experience in positional cloning, having served as one of the
primary researchers under genome programs sponsored by the United States
government, and has developed numerous techniques and tools that are widely used
in this field. GTC's commercial gene discovery strategy capitalizes on its
pioneering work in genomics by applying its proprietary high-throughput
multiplex DNA sequencing technology and positional cloning and bioinformatics
capabilities in two principal areas, the discovery and characterization (i.e.,
determination of functionality) of (i) genes of infectious organisms
("pathogens") that are responsible for many serious diseases and (ii) human
disease genes. The Company believes that its genomic discoveries may lead to the
development of novel therapeutics, vaccines and diagnostic products by it and
its strategic partners. In 1995, the Company entered into two corporate
collaborations in connection with its pathogen gene discovery programs, an
agreement with Astra Hassle AB ("Astra") and an agreement with Schering
Corporation and Schering-Plough Ltd. (collectively, "Schering-Plough").
 
SCIENTIFIC BACKGROUND
 
     Human disease is caused by a variety of factors, including genetic defects,
pathogens and environmental factors, with many of the most common
life-threatening and chronic diseases believed to have a genetic basis. Genes,
which define the inherited characteristics of an organism, are found in all
living cells (e.g., human, animal and pathogen cells). Each gene codes for a
specific protein that performs a specific function in the body, such as the
production of insulin. In humans, a defect in a gene, or the absence of a
critical gene, may lead to overproduction, underproduction, improper function or
absence of a protein resulting in the onset of disease or an undesirable
physical condition. Genetic defects can be inherited or can accumulate during
the lifetime of an individual. Human diseases caused by pathogens also have a
genetic foundation in that specific genes in the pathogen are required for that
organism to survive and infect its human host.
 
     The genetic content of an organism consists of DNA, a chemically complex
material comprised of four different nucleotides (adenine, guanine, cytosine,
and thymine) which are the building blocks of DNA. The sequence in which these
nucleotides are linked together in a molecule of DNA determines the
informational content of genes. The entire genetic content of an organism,
including humans, is referred to as its genome.
 
     The human genome consists of 23 pairs of DNA sequences or chromosomes.
These chromosomes contain approximately 100,000 human genes distributed over
approximately three billion nucleotides. Human genes are found in the
chromosomes as coding regions of DNA ("exons") interrupted by non-coding regions
of DNA ("introns"). The number of exons found in human genes can be quite large
as can be the distance between exons. The function of the majority of human DNA
is unknown. The DNA sequence of a human gene is transcribed into a messenger RNA
molecule ("mRNA") which is processed to contain only the exon sequences. The
information in the mRNA molecule is, in turn, translated into a protein product.
 
     Genomes of pathogens are significantly less complex than the human genome
and generally consist of a single chromosome containing several thousand genes
distributed over millions of nucleotides. The majority of DNA in pathogens
typically is comprised of genes as uninterrupted DNA sequences.
 
     Proteins expressed by genes are the targets of most current drugs. As a
result, the identification of human disease genes and the protein product of
these genes may lead to new therapeutics and diagnostic tests. In the case of
diseases caused by pathogens, the identification of the biologically important
genes of the pathogen may lead to the development of new drugs and vaccines to
combat the pathogen. Moreover, because of the simpler nature of the genomes of
pathogens relative to the human genome, efforts to identify and characterize
pathogen genes may lead to product development candidates more quickly than
human gene discovery efforts. The two principal technologies currently being
used to discover genes are sequencing and positional cloning.
 
                                        2

  Sequencing
 
     Sequencing is the process of identifying genes through the determination of
the order or sequence of nucleotides in DNA fragments. In recent years,
high-throughput procedures, such as those being employed by the Company, have
been developed which now enable sequencing to be performed on a larger scale and
with greater speed than was previously possible.
 
     There are generally two ways of applying high-throughput sequencing to
discover genes: random discovery and targeted discovery. In random discovery,
high-throughput sequencing is used to identify the genes in a genome without
regard to the function of the genes. In targeted discovery, high-throughput
sequencing is used to identify the genes in a specific chromosomal region or
tissue after the region or the tissue has been implicated in or associated with
a specific disease.
 
     High-throughput sequencing offers a practical way of randomly identifying
all of the genes in a pathogen because the genomes of pathogens consist of
relatively small numbers of uninterrupted gene sequences. In contrast, the human
genome is very large with only small portions of the DNA containing genes which
are present as interrupted DNA sequences. As a result, although high-throughput
sequencing of the DNA in a particular chromosomal region is used in human gene
discovery, sequencing of all of the DNA in the human genome is not a practical
means to identify large numbers of human genes. Instead, several groups are
randomly discovering large numbers of human genes by sequencing expressed copies
of genes, which contain only exons and are called cDNA, which they synthesize
from mRNA.
 
     Although random discovery permits the rapid identification of pathogen and
human genes, it generally does not provide an understanding of the function of a
gene or of the gene's role in a particular disease. Any determination of
function, or "characterization," of randomly discovered genes is dependent on
the detection of structural similarities, or homology, existing between the
protein product of such sequenced genes and genes with a known function.
 
     Targeted gene discovery by high-throughput sequencing of human DNA
typically is applied as part of positional cloning (described below) after a
specific chromosomal region has been identified which is believed to contain a
particular gene. In this targeted gene discovery procedure, the entire
chromosomal region is sequenced in an effort to identify, from all the genes
present in that region, the one gene located in that region which is responsible
for causing the specific disease.
 
     Another type of targeted gene discovery involves the use of high-throughput
sequencing of cDNA to identify genes believed to cause or maintain a particular
disease. In this procedure, which is referred to as "comparative gene
expression," mRNA present in healthy and diseased tissues is converted into cDNA
and then sequenced to identify the genes whose protein product is present in
each. Candidate genes responsible for causing or maintaining the disease are
identified by comparing which genes are expressing or producing their protein
product and at what level this expression is occurring in both the healthy and
diseased tissue.
 
  Positional Cloning
 
     Positional cloning is the process of analyzing disease inheritance patterns
to identify the genes responsible for causing human disease. The first step in
positional cloning is the identification of individual families or genetically
homogeneous populations in which the occurrence of the disease in individuals
within such families or populations is substantially higher than in the general
population. Blood samples are collected from individuals within the family or
population to provide DNA to be used to identify the region on a particular
chromosome where the disease-causing gene is located. This process is referred
to as "genetic linkage mapping."
 
     In genetic linkage mapping, DNA probes are used to detect genetic markers,
regions of DNA that vary in sequence content from person to person. The position
of these genetic markers on a chromosome, as detected by the DNA probes,
constitutes a genetic linkage map of the chromosome. The chromosomal regions
which are initially examined are those regions which have been identified as
containing genes that are likely candidates for causing or predisposing an
individual to the disease. Because very few human genes have been mapped to
date, most genetic mapping is done genome-wide with a set of DNA probes that
span the genome. By following the inheritance patterns of genetic markers and
looking for the coinheritance of the genetic markers and the disease, the gene
responsible for causing or predisposing an individual to that disease can be
 
                                        3
<PAGE>   5
 
located within a specific chromosomal region. Using additional DNA probes, the
chromosomal region containing the targeted disease gene can be narrowed to a
region consisting of approximately 2,000,000 to 3,000,000 nucleotides in size
containing between approximately 60 and 100 genes.
 
     Next, libraries comprised of large DNA fragments are examined to find those
fragments which contain pieces of DNA from the relevant chromosomal region. The
aligning of these DNA fragments so that their resulting order represents how
these DNA fragments are related to each other in the relevant chromosomal region
is called physical mapping. The physical map of the relevant chromosomal region
can then be used to identify the genes which are contained within the region.
These genes can be identified in two ways. First, "exon trapping" is used,
whereby individual exons within this chromosomal region can be isolated and then
used to obtain a complete copy of the gene from a cDNA library. Alternatively or
in combination with exon trapping, the DNA of the chromosomal region can be
sequenced using high-throughput procedures and, through the use of special
computer software, the exons which are contained within the chromosomal region
can be predicted. This sequencing information is then used to search cDNA
libraries for DNA fragments which contain these presumed exons.
 
     Each gene identified through this process is a candidate for causing the
disease. By determining the sequence of these genes in individuals with the
disease and comparing it to the sequence of that gene from healthy individuals,
the gene involved in the disease can be identified. DNA sequence differences,
which are only found in individuals who have inherited the disease, identify the
gene which is believed to be responsible for causing the disease.
 
COMPANY TECHNOLOGY
 
     The Company applies its proprietary technologies and know-how in
high-throughput multiplex sequencing and positional cloning in its gene
discovery programs. In its pathogen programs, the Company uses its
high-throughput sequencing capabilities to sequence the genomes of pathogens. In
its human gene discovery programs, the Company combines its proprietary
positional cloning capabilities, together with its high-throughput sequencing
capabilities, in its efforts to identify and characterize human genes associated
with disease. In support of these technologies, the Company has developed
sophisticated bioinformatics capabilities which utilize computer hardware and
proprietary software to track, process and analyze the data generated in the
gene discovery process.
 
  Multiplex Sequencing

     GTC uses its proprietary high-throughput DNA sequencing process, called
"multiplex sequencing," as its primary means to sequence DNA. The Company holds
exclusive worldwide commercial rights to this technology, which was originally
developed by Dr. George Church's laboratory at the Howard Hughes Medical
Institute ("HHMI"), pursuant to a license from Harvard College. See "Patents and
Proprietary Technology." Dr. Church is a scientific advisor to the Company. In
multiplex sequencing, individual DNA samples are mixed together and then
processed simultaneously. At the end of the process, the nucleotide sequence of
the individual DNA samples in the mixtures is determined by using DNA probes.
The Company has routinely combined up to 20 different DNA samples and used up to
40 different DNA probes to detect the sequence generated from each end of each
DNA fragment in the mixtures. By combining 20 different DNA samples into a
single mixture, the Company only has to perform a single series of preparatory
procedures to produce 40 different DNA sequences. Commercially available
automated DNA sequencers require 20 individual samples to be processed through
the preparatory procedures to produce the same number of DNA sequences.
 
     The Company has used its multiplex sequencing technology to sequence
virtually the entire genome of Helicobacter pylori ("H. pylori") and portions of
the genomes of three other pathogens (Staphylococcus auereus ("Staph."),
Microbacterium tuberculosis ("M. tuberculosis"), and Myclobacterium leprae ("M.
leprae")). The Company has also used multiplex sequencing to sequence a 60,000
nucleotide region of human chromosome 4 thought to contain the gene responsible
for fascioscapeulohumeral muscular dystrophy ("FSHD") and to sequence a 40,000
nucleotide region on human chromosome 10 which was subsequently determined by a
third party to contain the gene responsible for a type of thyroid cancer. 
 
                                        4
<PAGE>   6
     The Company's multiplex sequencing technology currently is semi-automated.
The Company is developing a fully-automated version of the process. The Company
has built prototype equipment to automate the use of DNA probes in multiplex
sequencing and expects to introduce this equipment into full-scale use in the
second half of 1996. This equipment will also automate the use of DNA probes in
the Company's multiplex genotyping technology. See "Company
Technology--Positional Cloning." The Company also plans to acquire robotic
laboratory equipment to automate the sample preparatory procedures required in
the sequencing process. The Company believes that automation will increase the
speed and lower the cost of sequencing DNA samples. The Company supplements its
proprietary multiplex sequencing technology with automated, commercially
available, DNA sequencers.
 
  Positional Cloning
 
     The Company has over 10 years of experience in various aspects of
positional cloning. GTC was one of the pioneers in the use of genetic linkage
mapping and developed numerous techniques and tools that are widely used in the
positional cloning field. In its positional cloning efforts, the Company applies
its proprietary multiplex genotyping technology. Genotyping is the process of
using DNA probes to determine the genetic composition of specific regions on
each chromosome of each family member. Using multiplex genotyping, the Company
has simultaneously processed up to 50 genetic markers for each family member in
a single sample mixture. By combining 50 different genetic markers, the Company
reduces the number of laboratory steps required to obtain the data needed to
localize a disease gene to a specific chromosomal region.
 
     The Company has considerable experience in identifying genetic markers for
specific chromosomal regions. This ability is needed when additional genetic
markers are required to narrow the size of the chromosomal region believed to
contain the disease gene. The Company also has several libraries of large DNA
fragments arranged in a format which facilitates the isolation of DNA fragments
from a specific chromosomal region. These libraries are used to develop physical
maps of chromosomal regions thought to contain disease genes. In addition, the
Company uses specialized tools to trap the exons present in large DNA fragments.
These tools are used to isolate exons from the genes present in chromosomal
regions believed to contain disease genes.

  Bioinformatics
 
     The process of identifying and characterizing genes generates vast amounts
of data which must be organized and managed. Such data result from genetic
linkage and physical mapping, DNA sequencing and biological experiments
performed on identified genes. The use of computers, software and databases to
track, process, store, retrieve and analyze data generated by genomic research
is referred to as "bioinformatics," which is an emerging subspecialty of
genomics and a key capability of any participant in the field. Because of its
early work in large-scale genetic linkage analysis, GTC was one of the first
companies to develop significant bioinformatics capabilities. The Company
expanded these capabilities several years ago when it began to use and further
develop its proprietary multiplex sequencing technology. The Company uses its
current bioinformatics systems to manage the production and interpretation of
multiplex sequence data and compare and screen these data against public and
proprietary sequence databases.
 
                                        5
<PAGE>   7
 
     The Company continually refines its bioinformatics systems. The Company
currently is focusing these efforts in four areas: upgrading and standardizing
its bioinformatics hardware and software; developing enhanced data management
systems; expanding its software engineering capabilities; and expanding its
resources in computational molecular biology. These enhancements are expected to
result in more effective data management by allowing for higher-throughput
sequencing, providing for smooth integration of laboratory automation,
supporting more rapid analyses and comparison of genomic data and facilitating
the identification of gene targets for the development of therapeutic, vaccine
and diagnostic products. As part of its enhancement of its bioinformatics
capabilities, the Company is in the process of significantly increasing the
number of its bioinformatics personnel.
 
GTC STRATEGY
 
     The Company's objective is to use its proprietary multiplex sequencing and
positional cloning technologies and bioinformatics capabilities to identify gene
targets for the development of novel therapeutic, vaccine and diagnostic
products in collaboration with pharmaceutical and biotechnology company
partners. The Company is using the following strategies to achieve this
objective:
 
  Sequencing of Pathogens
 
     Over the past four years, the Company has devoted a significant portion of
its resources to, and obtained considerable experience in, sequencing the
genomes of pathogens. The Company has sequenced virtually the entire genome of
H. pylori and portions of the genomes of three other disease-causing pathogens.
The Company plans to continue to identify and characterize genes of these and
other pathogens for which the Company believes new or improved therapeutic,
vaccine or diagnostic products represent a significant commercial opportunity.
In particular, the Company plans to focus its efforts on pathogens where the
incidence of antibiotic resistance or other factors limit the use or efficacy
of currently available therapies, creating a need for novel antibiotics and
vaccines. The Company believes its pathogen gene discovery programs may lead to
product development candidates more quickly than human gene discovery efforts.
 
  Discovery of Human Disease Genes
 
     In the human gene discovery area, the Company plans to build on its decade
of experience and knowledge in positional cloning and its proprietary multiplex
genotyping and multiplex sequencing technologies and bioinformatics capabilities
by obtaining exclusive rights to collections of DNA samples from relevant family
resources in order to map, identify and characterize genes responsible for
selected human diseases. The Company is seeking collaborations with clinicians
and academic researchers to obtain these rights. The Company believes that
access to these family and other resources will bolster its existing human gene
discovery programs and enable it to initiate additional programs directed at
human genes associated with significant diseases.
 
  Strategic Collaborations
 
     The Company plans to continue to seek strategic collaborations with
pharmaceutical and biotechnology companies for the development and
commercialization of products based on the Company's genomic discoveries. This
strategy is designed to provide the Company access to the scientific and product
development expertise of its partners and permit the Company to benefit from the
commercialization of products based on the Company's gene discoveries without
incurring the substantial costs required for pharmaceutical product development
and commercialization. The Company generally expects to exclusively license to
its partners all rights to therapeutic products and vaccines (and, depending
upon the gene, diagnostic products) developed based on the particular genetic
database licensed by the Company. In exchange, the Company generally expects to
receive a combination of up-front license fees, research funding, milestone
payments and royalty payments on product sales. To date, the Company has entered
into two collaborations relating to pathogens, one with Astra for the
development of therapeutic, diagnostic and vaccine products effective against
gastrointestinal infections and other diseases caused by H. pylori, and one with
Schering-Plough providing for the use by Schering-Plough of the genomic 
sequence of a specified pathogen that the Company is sequencing to identify 
new gene targets for the development of antibiotics and vaccines effective 
against drug resistant infectious organisms.
 
                                        6
<PAGE>   8
 
  Government Grants and Contracts
 
     The Company has served as one of the primary researchers under genomic
programs sponsored by the United States government and actively seeks to
continue its participation in government sponsored genomics research programs.
These programs add to the Company's genomics technology base and increase the
number and enhance the expertise of its scientific personnel. From January 1991
through August 1995, the United States government awarded the Company grants and
contracts providing for aggregate payments over their terms of approximately $36
million. Moreover, subject to certain rights of the government, under most of
these programs the Company becomes the owner of any resulting discoveries or
inventions.
 
GENE DISCOVERY PROGRAMS
 
     The Company is currently conducting gene discovery programs directed at
both pathogen genes and human disease genes. The factors the Company considers
in determining whether to initiate these programs include the projected
commercial potential, the effectiveness of current therapies, the likelihood of
attracting a pharmaceutical or biotechnology company as a collaborator, the
status of competitive programs and anticipated development costs.
 
  Pathogen Programs
 
     Antibiotics are the standard therapy for bacterial and fungal infections.
During the twelve month period ended November 1995, approximately 287 million
prescriptions for antibiotics were written in the United States for such
infections and approximately $7 billion was expended in the United States for
oral and injectable antibiotics. The approximately 100 antibiotics in use in the
United States today are primarily variations of a small number of original
antibiotic compounds. In the past decade, a growing number of infections have
been caused by pathogens which are becoming resistant to an increasing number of
currently available antibiotics. This problem of growing resistance to
antibiotics is particularly problematic in the approximately 6,500 acute care
hospitals in the United States in which approximately 2.1 million patients each
year develop infections. Examples of pathogens that have exhibited resistance to
a number of current antibiotics include Staph., M. tuberculosis, Streptococcus
pneumonia, and Enterococcus. To date, the primary response of pharmaceutical
companies to the resistance problem has been to modify existing antibiotics.
However, in many cases, the pathogens that are the targets of these antibiotics
have further mutated, often quite rapidly, and thereby developed resistance to
the modified antibiotics. The Company believes that the development of novel
antibiotics and vaccines based on new pathogen targets identified using genomic
information may be less prone to the rapid development of resistance than
antibiotics that are only modified versions of existing drugs.
 
     Helicobacter pylori.  H. pylori is the pathogen believed responsible for
causing 90% of duodenal peptic ulcers, the most common type of ulcer, and 70% of
gastric peptic ulcers. Peptic ulcer disease is a chronic inflammatory condition
of the stomach and duodenum. Although frequently asymptomatic, all persons
infected by H. pylori have chronic gastric inflammation (gastritis). It is
estimated that approximately 4.5 million people suffer from active peptic ulcers
each year, and approximately 500,000 new cases are diagnosed annually in the
United States. Approximately 600,000 patients are hospitalized each year in the
United States for peptic ulcer disease. Serious complications occur in
approximately one-third of these cases, including intestinal obstruction, upper
gastrointestinal hemorrhage and perforation. Further, each year over 6,000
deaths in the United States are directly caused by ulcer disease, and peptic
ulcers are a contributing factor in an additional 11,000 deaths. Approximately
10% of the population in the United States will develop peptic ulcer disease
during their lifetimes. Studies have also linked H. pylori with the development
of certain stomach cancers and coronary heart disease.
 
     The most common medication for treating peptic ulcers are anti-secretory
drugs, such as H2 antagonists (e.g., Tagamet and Zantac), and proton pump
inhibitors (e.g., Prilosec). Although anti-secretory drugs reduce ulcer symptoms
by inhibiting gastric acid secretion, they do not eradicate the H. pylori which
is the primary cause of the disease. In 1994, the market for such drugs for the
treatment of ulcers totaled approximately $7 billion worldwide. An approach
being developed to treat recurrent peptic ulcer disease recognizes the role of
H. pylori and involves the administration of antibiotics, often in combination
with bismuth or anti-secretory drugs. The most effective antibiotic treatments
may be complicated by the need to
 
                                        7
<PAGE>   9
 
treat for prolonged periods with multiple drugs, by side effects and problems
with patient compliance, by relapses if treatment is interrupted, and by the
development of antibiotic-resistant strains of the bacteria.
 
     Using its proprietary high-throughput multiplex sequencing technology, the
Company completed sequencing virtually the entire genome of H. pylori in
December, 1994. Under its agreement with Astra, the Company is identifying the
genes critical to the survival of H. pylori and proteins on the surface of the
bacterium that are believed to be likely targets for therapeutic products and
vaccines, respectively. See "Collaborative Agreements -- Pharmaceutical Company
Collaborations."
 
     Staphylococcus aureus.  Staph. is the most common cause of skin, wound and
blood infections. Staph. infections are typically treated with antibiotics. The 
percentage of Staph. isolates resistant to penicillin and certain other 
antibiotics increased from 2.4% in 1975 to 29% by 1991. Moreover, clinical
isolates of Staph. exist which are resistant to all known antibiotics other
than vancomycin. Vancomycin resistance has appeared in Enterococcus, a
pathogen related to Staph., which has raised the possibility that untreatable
strains of Staph. could appear. Using its high-throughput sequencing
capabilities, the Company has sequenced a substantial portion of the genome of
Staph.
 
     Mycobacterium tuberculosis.  M. tuberculosis is the pathogen responsible
for causing tuberculosis. The clinical manifestations of tuberculosis include:
pulmonary tuberculosis, the most highly infectious form; tuberculous meningitis,
the major form causing mortality in children; and disseminated tuberculosis of
bone or other internal organs, forms increasingly found in AIDS patients where
it causes chronic wasting and debilitation. Approximately one-third of the
world's population is infected with M. tuberculosis, but harbors the pathogen in
an inactive form. Such individuals have a 10% lifetime risk of developing the
disease. The fatality rate of untreated tuberculosis is between 40% and 60%.
Each year, there are an estimated 8 million new cases of tuberculosis worldwide
and 2.9 million deaths from the disease, making tuberculosis the leading cause
of death in the world from a single pathogen. While the disease is primarily
associated with the developing world, tuberculosis is not uncommon in
immuno-compromised patients, including cancer and AIDS patients. In the United
States, outbreaks of infection have occurred in health care workers and
residents of homeless shelters and prisons.
 
     The primary treatment for tuberculosis is the use of antibiotics. A problem
of effectively treating tuberculosis with antibiotics is compliance with the
long drug treatment regimens, often as long as six months. In addition, strains
of M. tuberculosis have become resistant to isoniazid and rifampicin, two
principal antibiotics used to treat tuberculosis. M. bovis vaccine, the most
widely used vaccine in the world, protects against disseminated tuberculosis and
tuberculosis meningitis in children. However, in clinical trials this vaccine
has been shown to be only partially effective against pulmonary tuberculosis in
adults.
 
     Using its high-throughput multiplex sequencing technology, the Company has
sequenced over 800,000 bases of the genome of M. tuberculosis, which the Company
estimates represents approximately 20% of the total genome of this pathogen. See
"Collaborative Agreements--Government Collaborations."

  Human Gene Discovery Programs

 
     GTC has initiated a variety of programs to identify human genes that are
responsible for various diseases. In some of these programs the Company is using
positional cloning strategies, while in others it is employing a multifaceted
approach incorporating both positional cloning and comparative gene expression.
The Company's current primary human gene discovery programs are directed at
FSHD, prostate cancer, BPH, and manic depressive illness. Most of the Company's
current human gene discovery programs target common diseases that are most
likely due to defects in more than a single gene. The following table summarizes
the current status of the Company's human gene discovery programs. This table is
qualified in its entirety by the more detailed descriptions contained elsewhere
in this 10-K.

     FSHD.  FSHD is a form of muscular dystrophy characterized by muscular
weakness and atrophy initially concentrated in the face and shoulder. FSHD is
believed to affect approximately one in 20,000 people worldwide. Steroids are
administered to patients with FSHD to decrease inflammation associated with
muscle wasting caused by the disease, but no therapies are available to reverse
or halt progression of the disease. Using detailed genetic linkage mapping,
physical mapping, and high-throughput multiplex sequencing, GTC has narrowed the
suspected location of the gene responsible for FSHD to an approximately 60,000
nucleotide region on the tip of the long arm of chromosome 4. The Company has
identified several candidate genes based on the sequence of this region and is
evaluating these candidates in affected individuals and normal controls. See
"Collaborative Agreements--Government Collaborations."
 
     Prostate Cancer.  In the United States, prostate cancer is the most
commonly diagnosed cancer in males and the second most common cause of death
from cancer in males. The American Cancer Society predicted that there would be
approximately 244,000 new cases of prostate cancer and approximately 40,000
deaths from prostate cancer in the United States in 1995. The treatment for
early stage prostate cancer is surgery to remove the prostate gland or
radiation. Removal of the prostate results in incontinence or impotence in a
substantial number of patients. Radiation is often not fully effective in
stopping the progression of the cancer. The treatment for later stage prostate
cancer is therapy to reduce testosterone levels. While testosterone reduction is
successful in slowing disease progression in 80% of patients, it is typically
effective for only 12 to 18 months.

<PAGE>   11
 
        GTC is conducting a multifaceted program to identify the genes
responsible for prostate cancer. First, based on academic research that used
genetic data obtained by comparing DNA isolated from tumors and blood samples
to localize a candidate tumor suppressor gene to a region on the long arm of
chromosome 10, the Company continues to refine its detailed physical map of the
region and is sequencing a set of DNA fragments which cover a portion of the
region. The Company, working with the National Institutes of Health (the
"NIH"), also has identified several candidate genes in the region using exon
trapping  techniques. In addition, the Company has initiated gene expression
profiles  for prostate cancer by constructing cDNA libraries from normal
prostate and  prostatic tumors and is sequencing the resulting cDNAs. GTC is
supplementing  its gene expression studies with technologies which are used to
determine the  differences in genes which are expressed in different samples.
To further this  program, the Company is also seeking to identify appropriate
families  exhibiting early onset (under 55 years of age) of prostate cancer for
genetic  linkage mapping efforts.

     GTC is collaborating with the NIH's National Center for Human Genome 
Research  ("NCHGR") in this program to identify and begin to evaluate candidate 
prostate cancer genes on the long arm of chromosome 10. Pursuant to the terms 
of the Company's Cooperative Research and Development Agreement ("CRADA") with 
NCHGR, any inventions or discoveries developed in the course of the research 
plan solely by the Company remain the property of the Company. Any inventions 
or discoveries developed by NCHGR researchers remain the property of the NIH 
and any inventions or discoveries developed jointly will be jointly owned. 
Under the terms of the CRADA, the Company has the right to negotiate with the
NIH to obtain an exclusive license to any inventions or discoveries not made
solely by the Company. The terms of any such license may include field of use 
restrictions and a royalty obligation on the part of the Company. The NIH 
retains a nonexclusive, nontransferable license to practice any such invention
or discovery by or on behalf of the United States government. The NIH is also
entitled to a license, including the right to grant sublicenses, to use for 
research purposes any such inventions or discoveries developed solely by the 
Company.            

     Benign Prostate Hypertrophy ("BPH").  BPH is a common disease in males that
results from enlargement of the prostate. Although BPH is non-life threatening,
it can have a significant effect on the quality of life. The peak age of onset
of symptoms of BPH is between 50 and 55. BPH affects approximately 40% of men in
the United States by the time they reach the age of 74. The current treatments
for BPH include transurethral resection of the prostate and drugs such as
Proscar. Resection of the prostate results in incontinence or impotence in a
substantial number of patients. Drugs such as Proscar are effective in treating
the early symptoms of BPH but are not effective as the prostate becomes
enlarged. GTC has initiated gene expression profiles for BPH by constructing
cDNA libraries from tissue exhibiting BPH, normal prostate tissue and prostate
tumors.
 
     Manic Depressive Illness.  Manic depressive illness is a serious
neuropsychiatric disorder characterized by alternating mood swings of mania and
depression. Manic depressive illness affects approximately one percent of the
United States population. The most common treatment for manic depressive illness
is lithium carbonate, which has both therapeutic and prophylactic effects but is
toxic at levels that are very close to therapeutic levels. Alternatives are
anticonvulsant agents such as carbamazepine, valproate, and clonazepam.
Treatments with either lithium carbonate or anticonvulsant agents result in
diminished intellectual and emotional capacity.
 
     GTC has been collaborating with the National Institute of Mental Health
(the "NIMH") in a search for DNA markers associated with this disorder in
several Old Order Amish pedigrees. This population represents a relatively
genetically isolated community with a small number of founders in the 1800's.
Strict pressures against substance abuse also facilitate accurate disease
diagnoses. The Company has completed a genome wide scan and has identified three
candidate chromosomal regions.
 
     Although NIMH funding for this program ends in March 1996, the Company
plans to continue this program with its own funds. Any gene discovered in the
course of research funded by the NIMH would be the property of the NIMH.
However, the NIMH has no rights to genes discovered by the Company after
expiration of the contract term. Based on the current status of the research in
this program, the Company believes that it is very unlikely that a gene will be
identified during the current term of the research contract.
 
     Other Programs.  The Company is also conducting preliminary research on
osteoporosis, asthma and schizophrenia. These diseases affect large numbers of
people in the United States and throughout the world and are believed to have a
genetic basis. The Company is currently evaluating various family resources for
research on these diseases and may expand its research on one or all of these
diseases.
 
COLLABORATIVE AGREEMENTS
 
     An important part of the Company's strategy is to pursue strategic
collaborations with pharmaceutical and biotechnology companies for the
development and commercialization of products based on the Company's genomic
discoveries. The Company also plans to continue to seek government grants and
research contracts related to the Company's technology and research programs.

  Pharmaceutical Company Collaborations
 
     Astra.  In August 1995, the Company entered into a collaboration agreement
with Astra to develop pharmaceutical, vaccine and diagnostic products effective
against gastrointestinal infections or any other disease caused by H. pylori.
The Company granted Astra exclusive access to the Company's H. pylori genomic
sequence database and exclusive worldwide rights to make, use and sell products
based on the Company's H. pylori technology. The agreement also provides for a
four-year research collaboration to further develop and annotate the Company's
H. pylori genomic sequence database, identify therapeutic and vaccine targets
and develop appropriate biological assays. This research is being directed by a
Joint Management Committee and a Joint Research Committee, each consisting of
representatives from both parties.
 
     Under this agreement, Astra agreed to pay the Company a minimum of
approximately $11 million and, subject to the achievement of certain product
development milestones, up to approximately $22 million (and possibly a greater
amount if more than one product is developed under the agreement) in license
fees, expense allowances, research funding and milestone payments. $500,000 of
such fees is creditable against any future royalties payable to GTC by Astra
under the agreement. The Company received approximately $5 million in license
fees, expense allowances and research funding under the Astra agreement through
December 1995. For the Company's fiscal year ended August 31, 1995, revenue 
recognized the Company under its agreement with Astra accounted for 
approximately 31% of the Company's total revenue. Astra is obligated to provide 
funding for the research program for a minimum of two and one-half years; Astra 
may terminate the research collaboration at any time after the second year on 
six months' notice.

     The Company will also be entitled to receive royalties on Astra's sale of
any products (i) protected by the claims of patents licensed exclusively to
Astra by the Company pursuant to the agreement, or (ii) the discovery of which
was enabled in a significant manner by the genomic database licensed to Astra by
the Company. GTC has the right under certain circumstances to convert Astra's
license to a nonexclusive license in the event Astra is not actively pursuing
commercialization of the licensed technology.

     Schering-Plough.  In December 1995, the Company entered into a     
collaboration and license agreement with Schering-Plough providing for the use
by Schering-Plough of the genomic sequence of a specified pathogen that the
Company is sequencing to identify new gene targets for development of
antibiotics effective against drug-resistant infectious organisms. As part
of this agreement, the Company granted Schering-Plough exclusive access to
certain of the Company's genomic sequence databases. The Company also granted
Schering-Plough a non-exclusive license to use the Company's bioinformatics
systems for Schering-Plough's internal use in connection with the genomic
databases licensed to Schering-Plough under the agreement and other genomic
databases Schering-Plough develops or acquires. The Company also agreed to
undertake certain research efforts to identify bacteria-specific genes
essential to microbial survival and to develop biological assays to be used by
Schering-Plough in screening natural product and compound libraries to identify
antibiotics with new mechanisms of action.
 
        Under the agreement, Schering-Plough made an up-front payment to the
Company of $3 million. In addition, upon completion of certain development
milestones, Schering-Plough has agreed to pay the Company a minimum of an
additional $10.3 million in research funding and milestone payments. Subject 
to the achievement of additional product development milestones and 
Schering-Plough's election to extend the research collaboration,
Schering-Plough has agreed to pay the Company up to an additional
approximately $40.5 million  (inclusive of the $10.3 million referred to in the
previous sentence) in research funding and milestone payments. The Company
expects that in fiscal 1996 it will complete the milestones that will entitle
it over the next several years to receive the minimum additional payments of
$10.3 million.
 
     The agreement grants Schering-Plough exclusive worldwide rights to make,
use and sell pharmaceutical and vaccine products based on the genomic sequence
databases licensed to Schering-Plough by the Company and on the technology
developed in the course of the research program. GTC has also granted
Schering-Plough a right of first negotiation if during the term of the research
plan GTC desires to enter into a collaboration with a third party with respect
to the development or sale of any compounds which are targeted against, as their
primary indication, the pathogen that is the principal subject of the Company's
agreement with Schering-Plough. The Company will be entitled to receive
royalties on Schering-Plough's sale of therapeutic products and vaccines
developed using the technology licensed from the Company. Subject to certain
limitations, GTC retained the rights to make, use,
        
                                       11
<PAGE>   13
 
and sell diagnostic products developed based on the Company's genomic database
licensed to Schering-Plough or the technology developed in the course of the
research program.
 
  Government Collaborations
 
     Since 1989, the Company has been awarded a number of grants and contracts
by various agencies of the United States government pursuant to the government's
genomics programs. The scope of the research covered by the grants and contracts
encompasses technology development, sequencing production, technology automation
projects and positional cloning projects. Among other things, these grants and
contracts have provided significant funds for the Company's M. tuberculosis,
FSHD and manic depressive illness gene discovery programs. These grants and
contracts represent an important aspect of the Company's strategy because they
add to the Company's genomics technology and enable the Company to increase the
number and enhance the expertise of its scientific personnel.

        Under the Company's government grants, the Company has, subject to
certain rights of the government described below, exclusive ownership rights to
any commercial applications of inventions first reduced to practice under the
grants, including all gene discoveries and technology improvements created or
discovered.  The Company is strongly encouraged under certain of the government
grants to make data and materials resulting from the research public within 180
days from the date such data and materials are developed.  Under the Company's
government research contracts, the government has ownership rights in the data,
clones, genes and other material derived from the material furnished to the
Company by the government, and the Company has ownership rights in other
inventions developed solely by the Company under the contracts.  The government
also retains certain rights described below under the caption "Patents and
Proprietary Technology," to the inventions first reduced to practice by the
Company under the government grants and contracts.  The Company currently has
two principal government research contracts, one with the National Institute of
Neurological Disorders and Stroke relating to the preparation of DNA samples
for sequencing, the isolation of DNA fragments and genotyping, and one with the
NIMH relating to the identification of genes responsible for manic depressive
illness.  See "Patent and Proprietary Technology" and "Human Gene Discovery
Programs - Manic Depressive Illness." 

     The Company's government grants and research contracts include both
cost-plus-fixed-fee arrangements and fixed price contracts. Under cost plus
fixed fee arrangements, the Company receives reimbursement of its direct costs
associated with the research, a portion of its indirect or overhead costs as
well as fees in excess of such costs. The amount of overhead reimbursement
varies with each contract. Under fixed price contracts, the Company agrees to
perform a particular research plan for an agreed upon payment.

 
     From January 1991 through August 1995, the United States government awarded
the Company grants and contracts providing for aggregate payments over their
terms of approximately $36 million. Listed below are the major government grants
and contracts under which the Company is currently performing services:

     These grants and research contracts are typically funded annually and
subject to the appropriation by the United States Congress of funding in each
year. In addition, funding under these grants and contracts may be discontinued
or reduced at any time by the United States Congress.
 
PATENTS AND PROPRIETARY TECHNOLOGY
 
     The Company's commercial success will be dependent in part on its ability
to obtain patent protection on genes, or products based on genes, discovered by
it. The current criteria for obtaining patent protection for partially sequenced
genes and for genes whose biological functions have not been characterized are
unclear. The Company's current strategy is to apply for patent protection upon
the identification of a novel gene or novel gene fragment and pursue claims to
these gene sequences as well as equivalent sequences, such as substantially
homologous sequences. Where the biological function of a gene or gene fragment
has not been characterized at the time of filing a patent application, the
Company intends to supplement such patent filing as soon as additional
information with respect to the biological function of such gene or gene
fragment is available. However, there can be no assurance that the Company will
be able to obtain patent protection on such genes or gene fragments, and even if
such patents are issued, the scope of the coverage or protection
 
                                       12
<PAGE>   14
 
provided by any such patents is uncertain. In addition, there can be no
assurance that any patents, if issued, will provide protection against any
competitors, will provide the Company with competitive advantages, will provide
protection for any therapeutic, vaccine or diagnostic products based on the
Company's gene discoveries or will not be successfully challenged by others.
Furthermore, others have filed and are likely to file in the future patent
applications which have not yet been published covering genes or protein
sequences similar or identical to the Company's. No assurance can be given that
any such patent application will not have priority over patent applications
filed by the Company or that any patent applications filed by the Company will
result in issued patents.
 
     There have been, and continue to be, intensive discussions on the scope of
patent protection for both gene fragments and full-length genes. In November
1995, the United States Patent and Trademark Office (the "PTO") scheduled a
hearing and requested public comment on the patenting of a complete genome of an
organism as well as the patenting of human gene fragments. Although the PTO
canceled the hearings and request for comments, they may be rescheduled at a
future date. There can be no assurance that these or other proposals will not
result in changes in, or interpretations of, the patent laws which will
adversely affect the Company's patent position. 

     The PTO issued new Utility Guidelines in July 1995 that address the
requirements for demonstrating utility, particularly in inventions relating to
human therapeutics. While the guidelines do not require clinical efficacy data
for issuance of patents for human therapeutics, the guidelines have been issued
only recently and there can be no assurance that the PTO's interpretations of
such guidelines, and any changes to such interpretations will not delay or
adversely affect the Company's or its collaborators' ability to obtain patent
protection. The biotechnology patent situation outside the United States is even
more uncertain and is currently undergoing review and revision in many
countries.
 
        The Company has filed patent applications with respect to a number of
full length genes and corresponding proteins and partial genes of H. pylori and
of M. leprae. The Company plans to file foreign counterparts of these U.S.
applications within the appropriate time frames. These applications seek to
protect these full length and partial gene sequences and corresponding
proteins, as well as equivalent sequences, such as substantially homologous
sequences, and products derived therefrom and uses therefor. These applications
also identify possible biological functions for the genes and gene fragments
based in part on a comparison to genes or gene fragments included in public
databases but do not contain any laboratory or clinical data with respect to
such biological functions. There are certain court decisions indicating that
disclosure of a partial sequence may not be sufficient to support the
patentability of a full-length sequence. The PTO initially rejected a patent
application by the NIH seeking protection for a substantial number of genes
based upon partial gene sequences, and the rejection was not appealed by the
NIH. In addition, the Company is aware of published patent applications owned
by third parties relating to nucleic acids encoding several H. pylori proteins.
Patents may issue thereon that have priority over the patent applications filed
by the Company, which may limit the scope of coverage or protection afforded by
any patent, if any, that may issue to the Company with respect to the genes of
H. pylori, or may preclude the issuance of any such patents.
 
     A number of groups are attempting to rapidly identify and patent gene
fragments and full length genes whose functions have not been characterized, as
well as fully characterized genes. To the extent any patents issue on such
partial or full length genes, the risk increases that the potential products of
the Company or its strategic partners may give rise to claims that such products
infringe the patents of others. Such groups could bring legal actions against
the Company or its collaborators claiming damages and seeking to enjoin drug
development efforts or the manufacturing or marketing of the affected products.
If any such actions are successful, in addition to any potential liability for
damages, the Company or its collaborators could be required to obtain a license
in order to continue to manufacture or market the affected products. There can
be
 
                                       13
<PAGE>   15
no assurance that the Company or its collaborators would prevail in any such
action or that any license required under any such patent would be made
available upon commercially acceptable terms, if at all. The Company believes
that there may be significant litigation in the industry regarding patent and
other intellectual property rights. If the Company becomes involved in such
litigation, it could consume a substantial portion of the Company's management  
and financial resources. 

     In addition, publication of information concerning genes or genetic
sequences prior to the time the Company applies for patent protection based on
the full-length gene could adversely affect the Company's ability to obtain
patent protection with respect to genes identified by it. Washington University
is currently identifying genes through partial sequencing pursuant to funding
provided by Merck & Co., Inc. and depositing the partial gene sequences
identified in a public database. In addition, Human Genome Sciences, Inc.
recently provided non-commercial research organizations access to human genetic
sequence data relating to between 30,000 and 50,000 genes from The Institute for
Genomic Research's Human cDNA Database. 

     Under the Company's government grants and contracts, the government has a
statutory right to practice or have practiced, and, under certain circumstances
(including inaction on the part of the Company or its licensees to achieve
practical application of the invention or a need to alleviate public health or
safety concerns not reasonably satisfied by the Company or its licensees), to
grant to other parties licenses under, any inventions first reduced to practice
under the government grants and contracts.  In addition, under the Company's
government research contracts, the government has ownership rights in the data,
clones, genes and other material derived from the material furnished to the
Company by the government, and the Company has ownership rights in other
technology developed solely by the Company under the contracts.  Under the
Company's CRADA with NIH, any inventions or discoveries made in whole or in
part by NIH researchers are the property, either solely or jointly with the     
Company, of NIH, and the Company has the right to negotiate with the NIH to
obtain an exclusive license to such inventions and discoveries.  The Company
is also strongly encouraged under certain government grants to make data and
materials resulting from the research public within 180 days from the date such
data and materials are developed.  If this requirement results in premature
publication of the Company's discoveries and inventions, the Company's ability
to obtain patent protection for such discoveries and inventions may be  
adversely affected.  

     Amendments to Title 35 of the U.S. Code pursuant to the General
Agreement on Tariffs and Trade, implementing the Uruguay Round Agreement Act of
1994 have affected the period of enforceability of United States patents. 
United States patents that issue from applications filed before June 8, 1995
will be enforceable for the longer of 17 years from the date of issue or 20
years from the earliest claimed priority date.  United States patents that
issue from applications filed on or after June 8, 1995 will be enforceable for
20 years from the earliest filing date or the earliest claimed priority date. 
While the Company cannot predict the effect that such laws will have on its
business, the adoption of such laws could effectively reduce the term during
which a marketed product is protected by patents.       

        The multiplex sequencing technology used by the Company was developed
by researchers at Harvard College and HHMI, Dr. George Church, a scientific
advisor to the Company. The multiplex sequencing technology is the subject of
two issued United States patents and foreign counterpart applications in
certain countries, but this technology is not covered by patents or patent
applications in all countries of the world. The Company has obtained an
exclusive worldwide license from  Harvard College to use the multiplex
sequencing technology for commercial applications. In situations where the
Company is unable to provide a third party with multiplex sequencing services,
it is obligated under the license to use reasonable efforts to sublicense the
multiplex sequencing technology to such third parties on commercially
reasonable terms except where doing so would place the Company at a materially
competitive disadvantage. This provision may require the Company to make the
multiplex sequencing technology licensed by it from Harvard College available
to third parties. Harvard College has retained the right to use and license
others to use the technology for research purposes. Under this license, the
Company paid Harvard College a nonrefundable license fee of $100,000 and must
pay Harvard College sublicensing fees, as well as royalties on products sold
that include the multiplex sequencing technology, services performed that
utilize the multiplex sequencing technology, income attributable to sublicenses
of the multiplex sequencing technology and certain other amounts. Under the
license, the Company must pay Harvard College minimum annual royalties ranging
from $15,000 in 1996 to $35,000 beginning in 1998. Under certain circumstances,
Harvard College has the right to convert the license to a nonexclusive license
if the Company has not put the technology into commercial use and is not
keeping the technology reasonably available to the public. In addition, the
HHMI, through Harvard College, has the right under certain circumstances, to
require the Company to license the technology to others if, in the judgment of
HHMI, the Company has not taken reasonable steps to achieve a practical
application of the technology or if required in response to public health or
safety needs. The Company continues to make improvements to the multiplex
sequencing technology with its own funds and funding provided under the
Company's $10.4 million Genome Sequencing Center grant from the NIH.  Subject
to the rights of the government described above in inventions developed by the
Company under government grants and the rights of Harvard College described
below, the Company owns any such improvements. The Company has granted
Harvard College a license to use the improvements the Company makes to the
software component of the multiplex sequencing technology for Harvard College's
internal academic purposes. In the event Harvard College desires to grant a
sublicense to any such improvements, the Company has agreed to negotiate with
Harvard College concerning the terms of any such sublicense. 

     The Company also relies on trade secret protection for its confidential
and  proprietary information. There can be no assurance that the Company can 
maintain adequate protection for its trade secrets or other proprietary 
information. In addition, while the Company has entered into proprietary 
information agreements with its employees, consultants and advisors, there can 
be no assurance that these agreements will provide meaningful protection for 
the Company's proprietary information in the event of unauthorized use or 
disclosure of such information. Moreover, there can be no assurance that others 
will not independently develop
 

                                      14
<PAGE>   16
 
substantially equivalent proprietary information and techniques or otherwise
gain access to the Company's trade secrets or disclose such technology, or that
the Company can meaningfully protect its trade secrets.
 
COMPETITION
 
     The Company faces intense competition both with respect to its human gene
and pathogen gene discovery programs. There is a finite number of genes in the
human genome and the Company believes virtually all of such genes will be
identified within two to three years albeit largely without known function. The
Company also believes that the primary genes that cause or predispose
individuals to most common diseases will be identified and characterized within
five to eight years. In addition, the Company believes that the genomes of many
commercially important pathogens will be sequenced within two to three years.
 
     Competitors of the Company include pharmaceutical and biotechnology
companies both in the United States and abroad. In addition, significant
research to identify and sequence genes is being conducted by universities,
other non-profit research institutions and United States and foreign
government-sponsored entities. A number of commercial, scientific and
governmental entities are attempting to sequence human genes and the genomes of
other organisms. Other entities are utilizing positional cloning to identify and
characterize human disease genes. Certain of the Company's competitors' human
gene programs are more advanced than the Company's and any one of these
companies or other entities may discover and establish a competitive advantage
in one or more pathogen development programs which the Company has commenced.
The Company also faces competition in its human gene discovery programs in
gaining access to family DNA samples for use in positional cloning.
 
     The Company believes that its ability to compete is dependent, in part,
upon its ability to create and maintain advanced technology, the speed with
which it can identify and characterize the genes involved in human diseases, the
Company's ability to rapidly sequence the genomes of selected pathogens, its
collaborators' ability to develop and commercialize therapeutic, vaccine and
diagnostic products based upon the Company's gene discoveries, as well as its
ability to attract and retain qualified personnel, obtain patent protection or
otherwise develop proprietary technology or processes and secure sufficient
capital resources for the expected substantial time period between technological
conception and commercial sales of products based upon the Company's gene
discoveries.
 
     Many of the Company's competitors have substantially greater research and
product development capabilities and financial, scientific, marketing and human
resources than the Company. These competitors may succeed in identifying or
sequencing genes or developing products earlier than the Company or its
collaborators, obtaining authorization from the FDA for such products more
rapidly than the Company or its collaborators or developing products that are
more effective than those proposed to be developed by the Company or its
collaborators. Any potential products based on genes identified by the Company
will face competition both from companies developing gene-based products and
from companies developing other forms of diagnosis or treatment for the
particular diseases targeted by the Company. There can be no assurance that
products developed by others will not render the products which the Company or
its collaborators may seek to develop obsolete or uneconomical or result in
diagnoses, treatments or cures superior to any products developed by the 
Company or its collaborators, or that any product developed by the Company or 
its strategic collaboration partners will be preferred to any existing or 
newly developed technologies.
 
GOVERNMENT REGULATION
 
     Regulation by governmental entities in the United States and other
countries will be a significant factor in the development, manufacturing and
marketing of any products which may be developed by the Company or its
collaborators. The nature and the extent to which such regulation may apply to
the Company or its collaborators will vary depending on the nature of any such
products. Virtually all of the Company's or its collaborators' pharmaceutical
products will require regulatory approval by governmental agencies prior to
commercialization. In particular, human therapeutic and vaccine products are
subject to rigorous preclinical and clinical testing and other approval
procedures by the United States Food and Drug Administration (the "FDA") in 
the United States and similar health authorities in foreign countries. Various 
federal and, in some cases, state statutes and regulations also govern or 
influence the manufacturing, safety, labeling, storage, record keeping and 
marketing of such products. The
 
                                       15
<PAGE>   17
 
process of obtaining these approvals and the subsequent compliance with
appropriate federal and foreign statutes and regulations are time consuming and
require the expenditure of substantial resources.
 
     The FDA regulates human therapeutic products in one of three broad
categories: drugs, biologics, or medical devices. Products based on the
Company's technologies could potentially fall into all three categories.
Generally, in order to gain FDA pre-market approval of a new drug or biological
product, a company first must conduct pre-clinical studies in the laboratory and
in animal model systems to gain preliminary information on an agent's efficacy
and to identify any safety problems. The results of these studies are submitted
as a part of an investigational new drug application ("IND"), which the FDA must
review before human clinical trials of a drug or biologic can commence. In order
to commercialize any products, the Company or its collaborators will be required
to sponsor and file an IND and will be responsible for initiating and overseeing
the clinical studies to demonstrate the safety, efficacy and potency that are
necessary to obtain FDA approval of any such products. Clinical trials are
normally done in three phases and are likely to take a number of years to
complete. After completion of clinical trials of a new product, FDA marketing
approval must be obtained. If the product is classified as a new drug, the
Company or its collaborators will be required to file a New Drug Application
("NDA") and receive approval before commercial marketing of the drug. If the
product is classified as a biologic (e.g., a vaccine), the Company or its
collaborator will be required to file a product license application and an
establishment license application ("ELA") and receive approval of both before
commercial marketing of the product can take place. The testing and approval
processes require substantial time and effort and there can be no assurance that
any approvals will be granted on a timely basis, if at all.
 
     Even if FDA regulatory clearances are obtained, a marketed product is
subject to continual review, and later discovery of previously unknown problems
or failure to comply with the applicable regulatory requirements may result in
restrictions on the marketing of a product or withdrawal of the product from the
market as well as possible civil or criminal sanctions. In addition, biologic
products may be subject to batch certification and lot release requirements. To
the extent that any of the Company's products involve recombinant DNA
technology, additional layers of government regulation and review are possible.
For marketing outside the United States, the Company will also be subject to FDA
export regulations and foreign regulatory requirements governing human clinical
trials and marketing approval for pharmaceutical products. The requirements
governing the conduct of clinical trials, product licensing, pricing and
reimbursement vary widely from country to country.
 
     The Company or its collaborators may also develop diagnostic products based
upon the human or pathogen genes that the Company identifies. The Company
believes that the diagnostic products to be developed by the Company or its
collaborators are likely to be regulated by the FDA as devices rather than drugs
or biologics. The nature of the FDA requirements applicable to such diagnostic
devices depends on their classification by the FDA. A diagnostic device
developed by the Company or a collaborator would most likely be classified as a
Class III device, requiring pre-market approval. Obtaining pre-market approval
involves the costly and time-consuming process, comparable to that for new drugs
or biologics, of conducting pre-clinical studies, obtaining an investigational
device exemption to conduct clinical tests, filing a pre-market approval
application, and obtaining FDA approval. Again, there can be no assurance that
any approval will be granted on a timely basis, if at all.
 
     The Company's research and development activities involve the controlled
use of hazardous materials, chemicals and various radioactive materials. The
Company is subject to federal, state and local laws and regulations governing
the use, storage, handling and disposal of such materials and certain waste
products. Although the Company believes that its safety procedures for handling
and disposing of such materials comply with the standards prescribed by state,
federal and local laws and regulations, the risk of accidental contamination or
injury from these materials cannot be completely eliminated. In the event of
such an accident, the Company could be held liable for any damages that result
and any liability could exceed the resources of the Company.
 
                                       16
<PAGE>   18
 
MANUFACTURING AND MARKETING
 
     The Company does not generally expect to directly manufacture or market
products in the near term. However, the Company may, in the future, consider
taking such actions if it believes they are appropriate under the circumstances.
The Company has no recent experience in developing pharmaceutical products or in
manufacturing or marketing products. The Company may not have the resources to
develop or to manufacture or market by itself any products based on genes
identified by it. In the event the Company decides to establish a manufacturing
facility, the Company will require substantial additional funds and will be
required to hire and train significant additional personnel and comply with the
extensive "good manufacturing practice" regulations applicable to such a
facility. In addition, if any products produced at the Company's facilities were
regulated as biologics, the Company would be required to file and obtain
approval of an ELA for its facilities.
 
 
HUMAN RESOURCES
 
     As of December 31, 1995, the Company had 125 full-time employees, of whom
110 were engaged in research and development activities, and 15 in general and
administrative functions. Twenty of the Company's employees hold Ph.D. degrees
and 38 others hold other advanced degrees.
 
     None of the Company's employees are covered by a collective bargaining
agreement, and the Company considers its relations with its employees to be
good.
 
SCIENTIFIC ADVISORS AND CONSULTANTS
 
     The Company's principal scientific advisors and consultants are individuals
with recognized expertise in fields related to the Company's technology and
development programs who advise the Company on an as-needed basis on scientific
matters that arise in the course of the Company's business. They are all
employed by academic institutions and may have commitments to, or consulting or

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

     The Company is engaged in the field of genomics -- the discovery and
characterization of genes. Currently, the Company's primary activity is genomic
research and development. For the past several years, the Company's primary
source of revenues have been government research grants and contracts and
collaborative agreements with pharmaceutical company partners. The Company
entered into corporate collaborations with Astra relating to H. pylori in August
1995 and with Schering-Plough in December 1995 providing for the use by
Schering-Plough of the genomic sequence of a specified pathogen that the Company
is sequencing to identify new gene targets for the development of novel
antibiotics.

 
     The Company will not receive significant product revenues on a sustained
basis until such time, if any, at which products based on the Company's research
efforts are commercialized. The Company's product development strategy is to
enter into collaborations with pharmaceutical and biotechnology companies
whereby these corporate partners will provide most or all of the financial and
other resources required to complete the development and to commercialize
products based on the Company's genomics research in exchange for a variety of
license and milestone payments, research support and royalties. In order for a
product to be commercialized based on the Company's research, it will be
necessary for the collaborators to conduct preclinical tests and clinical
trials, obtain regulatory clearances and make manufacturing, distribution and
marketing arrangements. Accordingly, the Company does not expect to receive
royalties based on product revenues for many years.
 
     For fiscal 1993, 1994, and 1995, the Company expended $4,950,000, 
$5,509,000 and $7,889,000, respectively on research and development, of which 
$4,527,000, $5,144,000 and  $6,414,000, respectively, was sponsored by the 
United States government. As of August 31, 1995, the Company had outstanding 
approximately $13,446,000 of government grants and research contracts 
under which services were yet to be performed. These grants and contracts call 
for these services to be performed over approximately the next 18 to 24 months.
The Company's government grants and contracts are typically funded annually
and are subject to appropriation by the United States Congress each year.
Funding may be discontinued or reduced at any time by the Congress. As of
August 31, 1995, the funded portion of these grants and contracts was 
$5,351,000. For fiscal 1993, 1994 and 1995 revenue recognized pursuant to United
States government grants and research contracts accounted for approximately
78%, 92% and 63%, respectively of the Company's total revenues. The Company
plans to continue to seek government grants and contracts in the genomics
field and to enter into additional corporate partnering arrangements with the
goal of advancing the Company's genomic technologies and gene discovery
programs and of obtaining revenues sufficient to cover a portion of the
Company's cash requirements. There can be no assurance that the Company will
be able successfully to pursue this strategy.
 
        The Company has incurred significant losses since inception, with an
accumulated deficit of approximately $35,174,000 at August 31, 1995. The
Company's results of operations have fluctuated from period to period and may
continue to fluctuate in the future based upon the timing and composition of
funding under existing and new government grants and contracts and
collaborative agreements. The Company is subject to risks common to companies
in its industry including, unproven technology and business strategy,
availability of, and competition for, family resources, reliance upon
collaborative partners and others, reliance on United States government
funding, history of operating losses, need for future capital, competition,
patent and proprietary rights, dependence on key personnel, uncertainty of
regulatory approval, uncertainty of pharmaceutical pricing, health care reform
and related matters, product liability exposure and the volatility of the
Company's stock price.

FISCAL YEARS ENDED AUGUST 31, 1995, 1994 AND 1993
 
  Revenue
 
     Total revenues increased 69% from $6,619,000 in fiscal 1994 to $11,207,000
in fiscal 1995 and increased 3% from $6,450,000 in fiscal 1993 to $6,619,000 in
fiscal 1994. Government research revenues increased 15% from $6,077,000 in
fiscal 1994 to $7,014,000 in fiscal 1995 and increased 21% from $5,022,000 in
fiscal 1993 to $6,077,000 in fiscal 1994. These increases in government research
revenues were primarily attributable to the commencement of payments under the
Company's 3-year, $10 million Genome Sequencing Center grant from the NIH, 
which was awarded in August 1994, as well as increased levels of funding under 
existing government grants and contracts. Revenue derived from government 
research grants and contracts is generally based upon direct costs such as 
labor and laboratory supplies as well as an allocation for reimbursement of a 
portion of overhead.



                                       22
<PAGE>   24
 
     Collaborative research, license fees and royalties increased from $314,000
in fiscal 1994 to $3,924,000 in fiscal 1995 primarily due to a $3,500,000
payment received from Astra in August 1995. Collaborative research, license fees
and royalties remained relatively unchanged in fiscal 1994 as compared to fiscal
1993. Product and service revenue significantly decreased after fiscal 1993 due
to the sale by the Company of its diagnostic testing business in June 1993.
 
     Interest income increased 64% from $142,000 in fiscal 1994 to $232,000 in
fiscal 1995, and decreased 19% from $174,000 in fiscal 1993 to $142,000 in
fiscal 1994. The changes in interest income reflect fluctuations in interest
rates as well as the increase in funds available for investment in fiscal 1995
as a result of the Company's sale of Common Stock in a private placement in
March 1995.
 
  Costs and Expenses
 
     Total costs and expenses increased 38% from $7,698,000 in fiscal 1994 to
$10,622,000 in fiscal 1995 and decreased 22% from $9,932,000 in fiscal 1993 to
$7,698,000 in fiscal 1994. The cost of government research increased 25% from
$5,144,000 in fiscal 1994 to $6,414,000 in fiscal 1995 and increased 14% from
$4,528,000 in fiscal 1993 to $5,144,000 in fiscal 1994. The increase in cost of
government research in both fiscal 1995 and fiscal 1994 was due primarily to
increases in payroll and related costs associated with the increase in
government research revenue as well as an increase in overhead expenses
associated with the expansion of the Company's facilities. Cost of government
research, as a percentage of government research revenue, was 91% in fiscal
1995, 85% in fiscal 1994 and 90% in fiscal 1993.
 
     Research and development expenses increased 304% from $365,000 in fiscal
1994 to $1,476,000 in fiscal 1995 and decreased 14% from $423,000 in fiscal 1993
to $365,000 in fiscal 1994. The increase in research and development expenses in
fiscal 1995 was primarily related to expenses incurred in connection with the
Company's H. pylori sequencing activities prior to entering into a collaborative
agreement with Astra in August 1995. The increase consisted primarily of
increases in payroll and related expenses, laboratory supplies and overhead
expenses. The decrease in research and development expenses in fiscal 1994 was
primarily related to the completion of certain research agreements and the
termination of research related to the Company's diagnostic testing business,
partially offset by increases in the Company's pathogen sequencing activities.
 
     Selling, general and administrative expenses increased 25% from $2,176,000
in fiscal 1994 to $2,730,000 in fiscal 1995 and decreased 22% from $2,802,000 in
fiscal 1993 to $2,176,000 in fiscal 1994. The increase in selling, general and
administrative expenses in fiscal 1995 was primarily due to approximately
$495,000 of severance and relocation expenses as well as increases in payroll
and related expenses and facilities expenses. The decrease in selling, general
and administrative expenses in fiscal 1994 was due primarily to the sale of the
diagnostics business in fiscal 1993 and cost cutting actions taken by the
Company in fiscal 1994.
 
     Cost of product and service significantly decreased after fiscal 1993 due
to the sale of the Company's diagnostic testing business in June 1993. The
Company sold substantially all of the assets used in this business in fiscal
1993 for $1,000,000, resulting in a loss of $637,000 in fiscal 1993.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     Since September 1, 1992, the Company's primary sources of cash have been
revenue from government grants and contracts, revenue from collaborative
research agreements, borrowing under capital leases and proceeds from the sale
of equity securities. In fiscal 1995, the Company received net proceeds of
approximately $2,403,000 from the private sale of Common Stock and warrants and
the exercise of stock options. In fiscal 1994, the Company received net proceeds
of approximately $1,601,000 from the sale of Common Stock and the exercise of
certain stock options. In August and December 1995, the Company entered into
collaborative arrangements under which it received $3,500,000 from Astra and
$3,000,000 from Schering-Plough, respectively.
 
     As of August 31, 1995, the Company had cash, cash equivalents and
marketable securities of approximately $9,011,000 (of which approximately
$784,000 is restricted in connection with certain capital lease obligations) and
working capital of approximately $5,499,000. The Company has various
arrangements under which it can finance up to $2,500,000 of certain office and
laboratory equipment and leasehold
 
                                       23
<PAGE>   25
improvements. Under these arrangements, the Company is required to maintain
certain financial ratios, including minimum levels of tangible net worth, total
indebtedness to tangible net worth, maximum loss, and minimum restricted cash
balances. At August 31, 1995, the Company had approximately $494,000
available under these arrangements and had an outstanding balance of
approximately $1,370,000, which is repayable over the three year period ending
August 1998.
 
     The Company's operating activities provided cash of approximately
$2,693,000 in fiscal 1995, including the utilization of approximately $1,100,000
of net operating loss carryforwards, and used cash of approximately $639,000 and
$3,252,000 in fiscal 1994 and 1993, respectively. Net cash provided in fiscal
1995 was composed primarily of deferred contract revenue, accrued expenses,
and operating income. Cash was utilized in fiscal 1994 and 1993 primarily to 
fund the Company's operating loss.

     The Company's investing activities provided cash of approximately $6,000 in
fiscal 1995. The Company's investing activities used cash of approximately
$1,550,000 and $1,548,000 in fiscal 1994 and 1993, respectively. The Company
used cash primarily for purchases of marketable securities and equipment and
leasehold improvements.
 
     Financing activities provided cash of approximately $2,074,000 and
$1,410,000 in fiscal 1995 and 1994 respectively, primarily from the sale of
equity securities and warrants and the exercise of stock options, net of
payments of capital lease obligations. Financing activities used cash of
approximately $451,000 in fiscal 1993 primarily for the payment of capital lease
obligations.
 
     Capital expenditures totaled $1,438,000 during fiscal 1995. The Company
currently estimates that it will acquire $1,500,000 of capital equipment during
fiscal 1996, consisting primarily of computer systems, laboratory equipment and
office equipment. The Company plans to utilize its capital lease arrangements
to finance the acquisition of this equipment.
 
     The Company believes that its existing capital resources are adequate to
meet its cash requirements for at least the next 24 months. There can be no
assurance, however, that changes in the Company's plans or other events
affecting the Company's operations will not result in accelerated or unexpected
expenditures.
 
     The Company may seek additional funding through public or private financing
and expects to seek additional funding through collaborative or other
arrangements with corporate partners. There can be no assurance, however, that
additional financing will be available from any of these sources or will be
available on terms acceptable to the Company.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
 
To Genome Therapeutics Corp.:
 
     We have audited the accompanying consolidated balance sheets of Genome
Therapeutics Corp. and subsidiaries (a Massachusetts corporation) as of August
31, 1994 and 1995, and the related consolidated statements of operations,
shareholders' equity and cash flows for each of the three years in the period
ended August 31, 1995. These financial statements are the responsibility of the
Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.
 
     We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
     In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of Genome Therapeutics Corp.
and subsidiaries as of August 31, 1994 and 1995, and the results of their
operations and their cash flows for each of the three years in the period ended
August 31, 1995, in conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
     Genome Therapeutics Corp. and Subsidiaries (the Company), is engaged in the
field of genomics -- the discovery and characterization of genes. The Company's
primary activity is genomic research and development.
 
     The accompanying consolidated financial statements reflect the application
of certain accounting policies described in this note and elsewhere in the
accompanying notes to the consolidated financial statements.
 
      (a) Revenue Recognition

     Research and contract revenues are derived from government grants and
contract arrangements as well as under collaborative agreements with
pharmaceutical companies. Research revenues are recognized as earned under
government grants, which consist of cost-plus-fixed-fee and fixed-price
contracts. Revenues are recognized under collaborative agreements as earned.
Milestone payments from collaborative research and development arrangements are
recognized when they are achieved. Unbilled costs and fees represent revenue
recognized prior to billing. Deferred contract revenue represents amounts
received prior to revenue recognition. Royalty revenue is recorded as earned.
 
      (b) Equipment and Leasehold Improvements
 
     Equipment and leasehold improvements are depreciated over their estimated
useful lives using the straight-line method. The estimated useful life for
leasehold improvements is the lesser of the term of the lease or the estimated
useful life of the assets. Equipment and all other depreciable assets useful
lives vary from three to ten years.
 
      (c) Net Income (Loss) per Common and Common Equivalent Share
 
     Net income per common and common equivalent share is computed by dividing
net income by the weighted average number of common and common equivalent shares
outstanding during the period using the treasury stock method. Net loss per
share is computed by dividing the net loss by the weighted average number of
common shares outstanding during the period.
 
      (d) Concentration of Credit Risk
 
     Statement of Financial Accounting Standards (SFAS) No. 105, Disclosure of
Information about Financial Instruments with Off-Balance-Sheet Risk and
Financial Instruments with Concentration of Credit Risk, requires disclosure of
any significant off-balance sheet and credit risk concentrations. The Company
has no significant off-balance sheet concentration of credit risk such as
foreign exchange contracts, options contracts or other foreign hedging
arrangements.

  (e) Use of Estimates in the Preparation of Financial Statements

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

  (f) Reclassifications
 
     The Company has reclassified certain prior year information to conform with
the current year's presentation.
 
(2) CASH EQUIVALENTS AND MARKETABLE SECURITIES

     The Company applies SFAS No. 115, Accounting for Certain Investments in
Debt and Equity Securities. The Company's cash equivalents and marketable
securities are classified as available-for-sale. Cash equivalents are
short-term, highly liquid investments with original maturities of less than
three months. Marketable securities are investment securities with original
maturities of greater than three months. Cash equivalents consist of money
market funds, repurchase agreements and debt securities. Marketable securities
are carried at fair market value which approximates amortized cost, accordingly
unrealized holding gains and losses were immaterial. The Company has not
recorded any realized gains or losses on its marketable securities. Marketable
securities consist of commercial paper with an average maturity of six months.
The Company has $94,674 and $784,471 in restricted cash at August 31, 1994 and
1995 in connection with certain capital lease obligations (see Note 7).
 
(3) INCOME TAXES
 
     The Company applies SFAS No. 109, Accounting for Income Taxes which
requires the Company to recognize deferred tax assets and liabilities for
expected future tax consequences of events that have been recognized in the
financial statement or tax returns. Under this method, deferred tax assets and
liabilities are determined based on the difference between the financial
statement and tax bases of assets and liabilities using the enacted tax rates in
effect for the year in which the differences are expected to reverse. SFAS No.
109 requires deferred tax assets and liabilities to be adjusted when the tax
rates or other provisions of the income tax laws change.
 
     At August 31, 1995, the Company had net operating loss and tax credit
carryforwards of approximately $35,007,000 and $1,120,000, respectively,
available to reduce federal taxable income and federal income taxes,
respectively, if any. Net operating loss carryforwards and credits are subject
to review and possible adjustments by the Internal Revenue Service and may be
limited in the event of certain cumulative changes in

(8) SHAREHOLDERS EQUITY
 
  (a) Private Placement
 
     On March 20, 1995, the Company completed a private placement of 850,000
shares of common stock at $2.43 per share resulting in proceeds of approximately
$2,000,000, net of issuance costs. In connection with the private placement, the
Company issued warrants to purchase 1,020,000 shares of common stock at an
exercise price of $2.43 per share. These warrants were exercised on July 18,
1995 through a cashless exercise and resulted in the net issuance of 603,023
shares of common stock. The net issuance represents the excess fair market value
of the shares purchasable pursuant to the warrants on the date of exercise over
the total exercise price of such warrants.
 
  (b) Series B Restricted Stock
 
     The Company has designated 625,000 shares of common stock as Series B
restricted stock (Series B Stock) and issued 57,512 shares of Series B Stock in
exchange for a subscription receivable. In the event of liquidation, holders of
common stock are entitled to receive, prior to and in preference to any
distribution of the Company's assets to the holders of Series B Stock, the
greater of (a) $5.00 per share or (b) an amount per share equal to 10 times the
amount which, after such distribution, would remain available for distribution
to holders of the Series B Stock. After such preferential distribution, the
remaining assets, if any, of the Company would be distributed ratably to the
holders of common stock and Series B Stock.
 
  (c) Stock Options and Warrants
 
     The Company has granted stock options to key employees and consultants
under its 1988, 1991, and 1993 Stock Option Plans. The purchase price and
vesting schedule applicable to each option grant are determined by the stock
option and compensation committee of the Board of Directors. Under separate
agreements not covered by any plan, the Company has granted a key employee, and
certain directors of the Company options to purchase common stock.
 
     
     The Company records deferred compensation when stock options are granted at
an exercise price per share which is less than the fair market value on the date
of the grant. Deferred compensation is recorded in an amount equal to the excess
of the fair market value per share over the exercise price times the number of
options granted. Deferred compensation will be recognized as an expense over the
vesting period of the underlying options. Compensation expense included in the
statement of operations was approximately

(10) COLLABORATION AGREEMENTS
 
  (a) Astra AB
 
     In August 1995, the Company entered into a collaboration agreement with
Astra Hassle AB (Astra) to develop pharmaceutical, vaccine and diagnostic
products effective against gastrointestinal infections or any other disease
caused by H. pylori. The Company granted Astra exclusive access to the Company's
H. pylori genomic sequence database and exclusive worldwide rights to make, use
and sell products based on the Company's H. pylori technology. The agreement
also provides for a four-year research collaboration to further develop and
annotate the Company's H. pylori genomic sequence database, identify therapeutic
and vaccine targets and develop appropriate biological assays. This research is
being directed by a Joint Management Committee and a Joint Research Committee,
each consisting of representatives from both parties.
 
     Under this agreement, Astra agreed to pay the Company a minimum of
approximately $11 million and, subject to the achievement of certain product
development milestones, up to approximately $22 million (and possibly a greater
amount if more than one product is developed under the agreement) in license
fees, expense allowances, research funding and milestone payments. $500,000 of
such fees is creditable against any future royalties payable to the Company by
Astra under the agreement. Astra is obligated to provide funding for the
research program for a minimum of two and one-half years; Astra may terminate
the research collaboration at any time after the second year on six-months'
notice.
 
     The Company will also be entitled to receive royalties on Astra's sale of
any products (i) protected by the claims of patents licensed exclusively to
Astra by the Company pursuant to the agreement, or (ii) the discovery of which
were enabled in a significant manner by the genomic database licensed to Astra
by the Company. The Company has the right, under certain circumstances, to
convert Astra's license to a nonexclusive license in the event Astra is not
actively pursuing commercialization of the license technology.
 
     In August 1995, the Company received $4,269,000, of which $3,500,000 was
recorded as a nonrefundable license fee and capital allowance which is included
in collaborative research, license fees and royalties on the accompanying
consolidated statement of operations, and $769,000 was recorded as deferred
revenue on the accompanying consolidated balance sheet. 

  (b) Schering-Plough

     In December 1995, the Company entered into a collaboration and license
agreement with Schering Corporation and Schering-Plough Ltd. (collectively
"Schering-Plough") providing for the use by Schering-Plough of the genomic
sequence of a specified pathogen the Company is sequencing to identify new gene
targets for development of antibiotics effective against drug-resistant
infectious organisms. As part of this agreement, the Company granted
Schering-Plough exclusive access to certain of the Company's genomic sequence
databases. The Company also granted Schering-Plough a non-exclusive license to
use the Company's bioinformatics systems for Schering-Plough's internal use in
connection with the genomic databases licensed to Schering-Plough under the
agreement and other genomic databases Schering-Plough develops or acquires. The
Company also agreed to undertake certain research efforts to identify
bacteria-specific genes essential to microbial survival and to develop
biological assays to be used by Schering-Plough in screening natural product and
compound libraries to identify antibiotics with new mechanisms of action.

     Under the agreement, Schering-Plough made an up-front payment to the
Company of $3 million. In addition, upon completion of certain development
milestones, Schering-Plough has agreed to pay the Company a minimum of an
additional $10.3 million in research funding and milestone payments. Subject to
the achievement of additional product development milestones and
Schering-Plough's election to extend the research collaboration, Schering-Plough
has agreed to pay the Company up to an additional approximately $40.5 million
(inclusive of the $10.3 million referred to above) in research funding and 
milestone payments.

     The agreement grants Schering-Plough exclusive worldwide rights to make,
use and sell pharmaceutical and vaccine products based on the genomic sequence
databases licensed to Schering-Plough by the Company and on the technology 
developed in the course of the research program. The Company has also granted 
Schering-Plough a right of first negotiation if during the term of the 
research plan the Company desires to enter into a collaboration with a third 
party with respect to the development or sale of any compounds which are 
targeted against, as their primary indication, the pathegon that is the 
principal subject of the Company's agreement with Schering-Plough. The Company 
will be entitled to receive royalties on Schering-Plough's sale of therapeutic 
products and vaccines developed using the technology licensed from the Company. 
Subject to certain limitations, the Company retained the rights to make, use, 
and sell diagnostic products developed based on the Company's genomic database 
licensed to Schering-Plough or the technology developed in the course of the 
research program.

(12) HARVARD LICENSE AGREEMENT
 
     On November 12, 1993, the Company entered into an agreement with Harvard
College for an exclusive worldwide license for commercial applications of their
patented multiplex sequencing technology. Under this agreement, the Company has
paid a nonrefundable license fee of $100,000, of which $50,000 can be credited
against future royalties. In addition, the Company must pay minimum royalties
ranging from $5,000 in 1995 to $35,000 in 1998. The Company may terminate this
agreement upon 90 day's notice.

     3.           RESEARCH COLLABORATION

     3.1          GTC undertakes to use all reasonable efforts to perform the
                  tasks assigned to it according to the Research Plan.

     3.2          For the purpose of the Research Collaboration , the parties
                  shall establish:

                  a     A JOINT MANAGEMENT COMMITTEE responsible for the
                        management and coordination of the Research
                        Collaboration  consisting of two representatives of
                        senior management from each party.  The chairman will be
                        designated by ASTRA from among the four representatives.
                        Decisions will be taken by majority vote except that in
                        the case of a deadlock the Chairman shall cast the
                        deciding vote.  Material changes in the Research Plan
                        shall be subject to the approval of the Joint Management
                        Committee.  In the event the Joint Management Committee
                        shall approve a change of direction and/or scope of the
                        Research Collaboration and such change would in the
                        absence of additional funding have an adverse economic
                        impact upon GTC, the parties agree to negotiate in good
                        faith an increase in the funding to be provided
                        hereunder by ASTRA so as to avoid such adverse economic
                        impact upon GTC and GTC shall not be required to incur
                        any additional expense until such agreement is in place.

                  b     A JOINT RESEARCH COMMITTEE responsible for the day to
                        day activities consisting of three representatives from
                        each party with the possibility to call in additional
                        members on an ad hoc basis. In case it is not possible
                        to reach consensus, the issue will be decided by the
                        Joint Management Committee.

       3.3        During the term of this Agreement, GTC shall not,  *

                                               , without ASTRA's prior written
                  consent given at its own discretion. However, GTC may search
                  and otherwise access all its databases including Helicobacter
                  spp and utilize information with respect thereto in its other
                  research programs provided (i) GTC  *

                  and (ii)  *

                                            .

       3.4        ASTRA has disclosed to GTC prior to the execution of this
                  Agreement certain ongoing research collaborations with third
                  parties involving Helicobacter spp. ASTRA may enter into
                  further collaborations related to Helicobacter spp with other
                  parties and GTC is prepared to collaborate with such parties,
                  reasonably acceptable to GTC, on behalf of ASTRA.

                        Collaboration have devoted not less than * man-years to
                        such research but in no event earlier than      *
                            .

       4.3        a)    Research support of       *      per man-year in
                        reimbursement of scientists of GTC actually engaged in
                        the  Research Collaboration payable in advance of each
                        quarter to which the same is attributable based upon
                        reasonable estimates (but after giving effect to any
                        debit or credit balance at the end of the prior period).
                        Within thirty (30) days following the end of each
                        quarter, GTC shall provide ASTRA with a written
                        statement specifying the scientists performing Research
                        Collaboration and the time devoted thereto by each of
                        them during the preceding quarter and a calculation of
                        the amount due for such quarter and the debit or credit
                        balance at the end of such quarter.  GTC will provide,
                        and ASTRA will support, a minimum of *  scientist man-
                        years for the first twelve (12) month period following
                        the Effective Date, a minimum of  * scientist man-years
                        for the ensuing twelve (12) month period and a minimum
                        of * scientist man-years for the subsequent six (6)
                        month period.  The number of scientist man-years in
                        excess of the minimum shall be subject to the approval
                        of ASTRA. The scientific man-years for any period
                        specified above or subsequently agreed upon, if any,
                        shall be spread during the period in such manner as may
                        be reasonably required by the normal course of the
                        Research Collaboration.  It is the expectation of the
                        parties that approximately      *     of the scientist
                        man-years for any such period shall be in relation to
                                        *                   .

                  b)    ASTRA shall reimburse GTC for each scientist engaged in
                        the Research Collaboration terminated by GTC for
                        customary out of pocket severance expense for a period
                        not exceeding six (6) months incurred by GTC as a result
                        of any reduction requested by ASTRA in

* Confidential Treatment Requested

                        the number of man-years required under this Agreement
                        provided that ASTRA's responsibility for severance for
                        each twelve (12) month period following the Effective
                        Date shall not exceed a number of scientists equal to
                        the aggregate decrease in the number of scientist
                        man-years for such year and further provided that ASTRA
                        shall have no responsibility for the first three
                        scientists terminated during such year. In order to
                        avoid scientist being terminated by GTC as aforesaid GTC
                        shall use all reasonable efforts to find other tasks for
                        scientists detached from the Research Collaboration.

                  c)    In order to make possible the control of the
                        calculations and payments provided for in this 4.3, the
                        records of the scientist performing Research
                        Collaboration  are open to inspection within two (2)
                        years after  the end of each calendar year by an
                        independent certified public accountant engaged and paid
                        by ASTRA and to whom GTC shall have no reasonable
                        objection.  Such accountant shall either confirm the
                        accuracy of the statement by GTC or provide the
                        necessary correction thereto but he shall not otherwise
                        disclose any records or other information.  In the event
                        that any such inspection shows an over- reporting and
                        overpayment GTC shall repay any additional sum that
                        would not have been payable had GTC reported correctly,
                        plus interest at the rate of 1.5% per month and, if such
                        overpayment is in excess of five percent (5%) for any
                        twelve (12) month period, GTC shall pay the cost of such
                        examination as well.

       4.4        MILESTONE PAYMENTS if and when the following events occur
                  payable within thirty (30) days after occurrence of the
                  respective event. However in relation to items a) (i)-(ii)
                  below ASTRA shall pay the respective amount thirty (30) days
                  following the receipt by ASTRA of a written statement from GTC
                  confirming the occurrence of the event, supported by adequate
                  documents reflecting the results of such events in reasonable
                  detail.

                        Payment to GTC shall be made within forty-five (45) days
                        after receipt by ASTRA of the payment from the
                        sublicensee to which the same is attributable and
                        adjustments, if necessary, shall be made when the Net
                        Sales of the sublicensee have been determined. ASTRA
                        shall furnish GTC with a complete and accurate copy of
                        each sublicense-contract regarding technology licensed
                        hereunder by GTC to ASTRA not less than ten (10) days
                        after the execution thereof. With respect to each such
                        sublicense, ASTRA shall furnish to GTC the same reports
                        that ASTRA receives from such sublicensee regarding any
                        payment from such sublicensee to ASTRA with respect to
                        which GTC is entitled to a payment from ASTRA hereunder.
                        GTC agrees to keep each sublicense-contract and the
                        related reports confidential and use the same only for
                        the purpose of verifying the accuracy of payments made
                        by ASTRA to GTC hereunder. If a sublicensee is
                        compensating ASTRA in other than cash then the payment
                        to GTC shall be based upon the then fair market value
                        thereof.

                  (d)   The term "Net Sales" as used herein shall mean the
                        actual gross selling prices charged by ASTRA for the
                        Products in bona fide sales to third parties as per
                        invoices covering the sales of such Products less only
                        the deductions taken by ASTRA to determine its net sales
                        for purposes of the Group Consolidated Statement of
                        Earnings of Astra AB disseminated to its shareholders
                        and the public generally.

                  (e)   ASTRA shall for each calendar quarter following the
                        launch of a Product, no later than sixty (60) days
                        following each quarter prepare and mail a statement
                        showing the total Net Sales in respect of which
                        royalties according to this Article 4. are payable.
                        Payments of such royalties shall be effected
                        simultaneously with mailing the statement.

                        Such statements shall contain at least the following
                        information: (i) the number of packages of each Product
                        sold by ASTRA in each country; (ii) the Net Sales and
                        (iii) the amount of royalty due. Such statement shall be
                        certified as by an officer of ASTRA. If no royalties are
                        due to GTC for any reporting period, the written report
                        shall so state.

                  (f)   Upon GTC's request ASTRA shall for each Product furnish
                        GTC with a supplement to the statement required in (e)
                        above with respect to the U.S. and one other country to
                        be specified by GTC in its notice of request to ASTRA
                        setting forth each category (eg. freight, insurance,
                        etc.) of the deductions taken by ASTRA from the actual
                        gross selling prices charged by ASTRA for the Products
                        to determine Net Sales to the extent consistent with the
                        then existing bookkeeping for such country and stating
                        the total amount of deductions for each such category.
                        GTC may only make such request once in any twelve month
                        period. Specification by GTC of a particular country in
                        one twelve month period shall not preclude the
                        specification of the same or a different country in
                        another twelve month period.

                  (g)   ASTRA's obligation to pay royalty and other
                        remunerations set out above in this Article 4.6 shall
                        for each country and each separate Product remain in
                        force for so long as ASTRA is the holder of a valid
                        product patent protecting the respective Product or in
                        case of a Product not protected by a valid product
                        patent of ASTRA until    *     following the commercial
                        launch of the Product in each country.

                  (h)   All payments due hereunder shall be payable in United
                        States dollars. Conversion of foreign currency to U.S.
                        dollars shall be made at the conversion rate existing in
                        the United States (as reported by the Wall Street
                        Journal) on the last working day of each royalty period.
                        Such payments shall be without deduction of exchange,
                        collection or other charges except charges of receiving

                        month.

                 (i)    If transfer to U.S. dollars is subject to administrative
                        authorization, ASTRA undertakes to file the transfer
                        application with the competent authorities supported by
                        all requisite documentation, and to apply its reasonable
                        efforts to obtain such authorization and effect the
                        remittance within the period laid down above.  ASTRA
                        further agrees to effect the transfer within thirty (30)
                        days following the date on which authorization shall
                        have been granted, provided that ASTRA shall not be
                        obligated to pay before the date stipulated above.

                 (j)    If for any reason beyond the control of ASTRA the
                        transfer of payments under this Section 4 are not
                        effected within the period hereinabove provided or
                        within such further period of time that GTC may allow,
                        ASTRA shall settle such payments as soon as the
                        impediment has ceased to exist.

                 (k)    In order to make possible the control of the
                        calculations and payments provided for in this 4.6, the
                        records of sales of  Products entitling GTC to royalty
                        and other payments under this 4.6 are open to inspection
                        within two (2) years after  the end of each calendar
                        year by an independent certified public accountant
                        engaged and paid by GTC and to whom ASTRA shall have no
                        reasonable objection.  Such accountant shall either
                        confirm the accuracy of the statement by ASTRA or
                        provide the necessary correction thereto but he shall
                        not otherwise disclose any records or other information.
                        In the event that any such inspection shows an
                        under-reporting and underpayment ASTRA shall pay any
                        additional sum that would have been payable to GTC had
                        ASTRA reported correctly, plus interest at the rate of
                        1.5% per month and, if such underpayment is in excess of
                        five percent (5%) for any twelve (12) month period,
                        ASTRA shall pay the cost of such examination as well

       4.7       ASTRA shall pay to GTC within thirty (30) days following the

                 a milestone payment of at least      *      is also payable (if
                 a lesser or no milestone is payable, ASTRA may satisfy this
                 condition by paying the difference) or (b) ASTRA is supporting
                 at least    *       man-years at GTC engaged in the research
                 under this Agreement. In case termination of this Agreement
                 shall become effective on a date not being the anniversary of
                 the Effective Date the above sum of      *       shall be
                 pro-rated.

       4.8       Except as otherwise specifically provided herein, ASTRA shall

       8.        INTELLECTUAL PROPERTY RIGHTS

       8.1       Each party agrees to use all reasonable efforts to see to it
                 that all its employees and other persons engaged by it, are
                 committed in such a way that the rights to the GTC Helicobacter
                 Technology,          *           Software Technology, to the
                 extent proprietary to GTC, and the Resulting Technology are
                 secured to the effect described in Articles 5.1 and 6.1.

       8.2       The procurement, maintenance, defense and actions for
                 infringement of patents and other intellectual property rights
                 related to Resulting Technology and (for so long as ASTRA's
                 license according to Article  5  is on an exclusive basis) GTC
                 Helicobacter Technology, excluding           *            (the
                 "IP-Rights") are the concern of ASTRA. ASTRA shall handle such
                 matters at its own cost and discretion subject to Articles 8.3
                 - 8.4:

       8.3       GTC shall at ASTRA's expense cooperate fully in the
                 preparation, filing, prosecution, maintenance, defense and
                 actions for infringement of the IP-Rights, executing all
                 papers and instruments and taking other reasonable measures or
                 requiring members of GTC to execute such papers and instruments
                 or to take other reasonable measures so as to enable ASTRA to
                 accomplish the foregoing, Article 8.2, in its own name in any
                 country. Each party shall provide to the other prompt notice as
                 to all substantial matters which come to its attention and
                 which relates to the preparation, filing, prosecution
                 maintenance, defense or infringement of the IP-Rights.

       8.4       If ASTRA or its sublicensee elects to commence an action for
                 infringement and GTC is a legally indispensable party to such
                 action, GTC shall have the right to assign to ASTRA all of
                 GTC's right, title and interest in each patent which is the
                 subject of such action. In the event that GTC makes such an
                 assignment, such assignment shall be irrevocable, and such
                 action by


                                       14

* Confidential Treatment Requested

                  ASTRA on that patent or patents shall thereafter be brought or
                  continued without GTC as a party.  Notwithstanding any such
                  assignment to ASTRA by GTC and regardless of whether GTC is or
                  is not an indispensable party, GTC shall cooperate fully with
                  ASTRA in connection with any such action.  In the event that
                  any patent is assigned to ASTRA by GTC, pursuant to this
                  paragraph, such assignment shall require ASTRA to continue to
                  meet its obligations under this Agreement as if the assigned
                  patent or patent application were still licensed to ASTRA.

     8.5          No settlement, or consent judgment of any suit to which GTC is
                  a party may be entered into without the consent of GTC, which
                  consent shall not be unreasonably withheld.  No consent shall
                  be required if the relief against GTC is solely monetary and
                  ASTRA agrees to hold GTC harmless therefrom.

     8.6          Recoveries or reimbursements from actions for infringement as
                  contemplated by this Article 8 shall first be applied to
                  reimburse ASTRA and GTC for litigation costs. Recoveries or
                  reimbursements representing lost sales or profits of a Product
                  shall be shared by ASTRA  *  and GTC  * .  Any remaining
                  recoveries or reimbursements representing infringement of GTC
                  Helicobacter Technology shall be shared by ASTRA  *  and GTC
                   * . Any remaining recoveries or reimbursements representing
                  infringement of Resulting Technology shall be retained by
                  ASTRA.

     8.7          In the event that a declaratory judgment action alleging
                  invalidity of any of the GTC Helicobacter Technology shall be
                  brought against ASTRA or GTC, GTC at its sole option, shall
                  have the right to intervene at its own expense subject to
                  ASTRA's right to control the process.

     8.8          ASTRA may, at its own discretion, renounce its claims to
                  certain rights included in the IP-Rights, whereupon ASTRA
                  shall have no responsibilities or liabilities in relation to
                  such IP-Rights. ASTRA shall promptly notify GTC of any such
                  renouncement and GTC shall have the option of acquiring such
                  IP-Rights without paying any compensation to ASTRA.

                  other things, prohibit or require a license for the export of
                  certain types of technical data to certain specified
                  countries.  ASTRA hereby agrees and gives written assurance

                  technical data, that it will be solely responsible for any
                  violation of such by ASTRA or sublicensees, and that it will
                  defend and hold GTC harmless in the event of any legal action
                  of any nature occasioned by such violation.

     14.2         EXCEPT AS OTHERWISE SET FORTH IN THIS AGREEMENT GTC EXPRESSLY
                  DISCLAIMS ANY AND ALL IMPLIED OR EXPRESS WARRANTIES AND MAKES

                  GTC further acknowledges and agrees that GTC will be entitled

                         claims, suits, actions, demands or judgments arising

                         claim or action to ASTRA and assists ASTRA, at ASTRA s
                         expense, in defending such claim or action and does not
                         compromise or settle such claim or action without ASTRA
                         s prior written consent, provided, however, that ASTRA
                         s indemnification of the Indemnitee hereunder shall not
                         extend to any cost, claim, suit, expense or damage
                         which arises or results from negligence or intentional
                         misconduct of the Indemnitee, or any third party for
                         whom GTC is responsible.

                  (b)    ASTRA agrees, at its own expense, to provide attorneys
                         reasonably acceptable to GTC to defend against any
                         actions brought or filed against any party indemnified
                         hereunder with respect to the subject of indemnity
                         contained herein, whether or not such actions are
                         rightfully brought.

                  hereof will be null and void without the prior written consent

6.   In order to redistribute awards more evenly throughout the year, grant
budget periods are being adjusted.  This award is issued for 10 months; future
continuation awards will cycle each year on July 1.  Non-competing continuation
applications are due two months prior to this date.  Allowable preaward costs
may be charged to this award, in accordance with the conditions outlined in the
PHS Grants Policy Statement, revised April 1, 1994, and with institutional
requirements for prior approval.

7.   Allowable costs of activities conducted by for-profit organizations will
be determined by applying the costs principles of Contracts with Commercial
Organizations set forth in 48 CFR 31.2.  However, independent research and
development costs (including the indirect costs allocable to them) are
unallowable.

                  NIH-DOE GUIDELINES FOR ACCESS TO MAPPING AND
                     SEQUENCING DATA AND MATERIAL RESOURCES(1)

The information and resources generated by the Human Genome Project have become
substantial, and the interest in having access to them is widespread.  It is
therefore desirable to have a statement of philosophy concerning the sharing of
these resources that can guide investigators who generate the resources as well
as those who wish to use them.

A key issue for the Human Genome Project is how to promote and encourage the
rapid sharing of material and data that are produced, especially information
that has not yet been published or may never be published in its entirety.
Such sharing is essential for progress toward the goals of the program and to
avoid unnecessary duplication.  It is also desirable to make the fruits of
genome research available to the scientific community as a whole as soon as
possible to expedite research in other areas.

Although it is the policy of the Human Genome Project to maximize outreach to
the scientific community, it is also necessary to give investigators time to
verify the accuracy of their data and to gain some scientific advantage from
the effort they have invested.  Furthermore, in order to assure that novel
ideas and inventions are rapidly developed to the benefit of the public,
intellectual property protection may be needed for some of the data and
materials.

After extensive discussion with the community of genome researchers, the
advisors of the NIH and DOE genome programs have determined that consensus is
developing around the concept that a 6 month period from the time the data or
materials are generated to the time they are made available publicly is a
reasonable maximum in almost all cases.  More rapid sharing is encouraged.

Whenever possible, data should be deposited in public databases and materials
in public repositories.  Where appropriate repositories do not exist or are
unable to accept the data or materials, investigators should accommodate
requests to the extent possible.

The NIH and DOE genome programs have decided to require all applicants
expecting to generate significant amounts of genome data or materials to
describe in their application how and when they plan to make such data and
materials available to the community.  Grant solicitations will specify this
requirement.  These plans in each application will be reviewed in the course of
peer review and by staff to assure they are reasonable and in conformity with
program philosophy.  If a grant is made, the applicant's sharing plans will
become a condition of the award and compliance will be reviewed before
continuation is provided.  Progress reports will be asked to address the issue.

1.   The Fiscal 1995 Appropriations Act prohibits reimbursement of direct
salary for individuals at a rate greater than $125,000 per year as determined
in the original award.  The language contained in the Appropriations Act
follows:

          "None of the funds appropriated in this title for the National
          Institutes of Health and the Substance Abuse and Mental Health
          Services Administration shall be used to pay the salary of an
          individual through a grant or other extramural mechanism at a rate in
          excess of $125,000 per year."

2.   It is the current practice of the NCHGR to mail the original Notice of
Grant Award (NGA) and Terms and Conditions to the Business Official of the
grantee organization.  Since this is the ONLY notification which will be
provided to your institution it is the responsibility of the grantee Business
Office to make distribution of the NGA and Terms and Conditions to the
Principal Investigator and other staff.

3.   Pursuant to the NIH Revitalization Act (P.L. 103-43, June 10, 1993),

and sequencing data and materials resources, adopted by the NIH-DOE joint
subcommittee on December 7, 1992 (see attached).

5.   Allowable costs of activities conducted by for-profit organizations will
be determined by applying the costs principles of Contracts with Commercial
Organizations set forth in 48 CFR 31.2.  However, independent research and
development costs (including the indirect costs allocable to them) are
unallowable.

6.   Any invention developed under this award should be reported to the Patent

1. The Appropriations Act prohibits reimbursement of direct salary for
individuals at a rate greater than $125,000 a year as determined in the original
award. The language contained in the Appropriations Act follows:

     "None of the funds appropriated in this title for the National Institutes
     of Health and the Alcohol, Drug Abuse, and Mental Health Administration
     shall be used to pay the salary of an individual, through a grant or other
     extramural mechanism, at a rate in excess of $125,000 per year."

2. Allowable activities conducted by for-profit organizations will be determined
by applying the cost principles of contracts with Commercial Organizations set
forth in 48 CFR Subpart 31.2. Independent research and development costs are
unallowable.

3.  All prior approvals, where required, remain with the awarding unit.

4. This grant is in the final budget period. Unless an application for
competitive renewal is funded, grant closeout documents must be submitted within
90 days of the end of the current budget period. Documents required are a
Financial Status Report (FSR), Final Invention Statement and Final Progress
Report. The Final Progress Report may be typed on plain white paper and should
include, at a minimum, a summarization of progress toward the achievement of the
originally stated aims, a list of results (positive or negative) considered
significant, and a list of publications resulting from the project as well as a
plan for future publications. An original and one copy are required. Please send
the Final Progress Report and Invention Statement to the following address:

MAO, JEN-I, PH.D.

1. The Fiscal 1995 Appropriations Act prohibits reimbursement of direct salary
for individuals at a rate greater than $125,000 per year as determined in the
original award. The language contained in the Appropriations Act follows:

     "None of the funds appropriated in this title for the National Institutes
     of Health and the Substance Abuse and Mental Health Services Administration
     shall be used to pay the salary of an individual through a grant or other
     extramural mechanism at a rate in excess of $125,000 per year."

2. It is the current practice of the NCHGR to mail the original Notice of Grant
Award (NGA) and Terms and Conditions to the Business Official of the grantee
organization. Since this is the ONLY notification which will be provided to your
institution it is the responsibility of the grantee Business Office to make
distribution of the NGA and Terms and Conditions to the Principal Investigator
and other staff.

3. Pursuant to the NIH Revitalization Act (P.L. 103-43, June 10, 1993), Section
2004, when purchasing equipment or products under this assistance award, the
recipient should whenever possible, purchase only American-made items.

4. Allowable costs of activities conducted by for-profit organizations will be
determined by applying the costs principles of Contracts with Commercial
Organizations set forth in 48 CFR 31.2. However, independent research and
development costs (including the indirect costs allocable to them) are
unallowable.

5. Normally, the awardee organization retains the principal worldwide patent
rights to any invention developed with United States government support. Under
Title 37 Code of Federal Regulations Part 401, the Government receives a
royalty-free license for its use, reserves the right to require the patent
holder to license others in certain circumstances, and requires that anyone
exclusively licensed to sell the invention in the United States must normally
manufacture it substantially in the United States. To the extent authorized by
Title 35 United States Code Section 205, the Government will not make public any
information disclosing a Government-supported invention for a 4-year period to
allow the awardee organization a reasonable time to file a patent application,
nor will the Government release any information that is part of that
application.

                  NIH-DOE GUIDELINES FOR ACCESS TO MAPPING AND
                   SEQUENCING DATA AND MATERIAL RESOURCES(1)

The information and resources generated by the Human Gemone Project have become
substantial, and the interest in having access to them is widespread. It is
therefore desirable to have a statement of philosophy concerning the sharing of
these resources that can guide investigators who generate the resources as well
as those who wish to use them.

A key issue for the Human Genome Project is how to promote and encourage the
rapid sharing of material and data that are produced, especially information
that has not yet been published or may never be published or may never be
published in its entirety. Such sharing is essential for progress toward the
goals of the program and to avoid unnecessary duplication. It is also desirable
to make the fruits of genome research available to the scientific community as a
whole as soon as possible to expedite research in other areas.

Although it is the policy of the Human Genome Project to maximize outreach to
the scientific community, it is also necessary to give investigators time to
verify the accuracy of their data and to gain some scientific advantage from the
effort they have invested. Furthermore, in orderto assure that novel ideas and
inventions are rapidly developed to the benefit of the public, intellectual
property protection may be needed for some of the data and materials.

After extensive discussion with the community of genome researchers, the
advisors of the NIH and DOE genome programs have determined that consensus is
developing around the concept that a 6 month period from the time the data or
materials are generated to the time they are made available publicly is a
reasonable maximum in almost all cases. More rapid sharing is encouraged.

Whenever possible, data should be deposited in public databases and materials in
public repositories. Where appropriate repositories do not exist or are unable
to accept the data or materials, investigators should accomodate requests to the
extent possible.

The NIH and DOE genome programs have decided to require all applicants expecting
to generate significant amounts of genome data or materials to describe in their
application how and when they plan to make such data and materials available to
the community. Grant solicitations will specify this requirement. These plans in
each application will be reviewed in the course of peer review and by staff to
assure they are reasonable and in conformity with program philosophy. If a grant
is made, the applicant's sharing plans will become a condition of the award and
compliance will be reviewed before continuation is provided. Progress reports
will be asked to address the issue.

             (b)    The fixed-fee for this contract is $135,023.000.  The fee 
                    shall be paid in direct ratio to the level of effort
                    expended; that is, the percent of fee paid shall be equal
                    to the percent of effort actually expended.  Payment shall
                    be subject to the withholding provisions of the clauses
                    Allowable Cost and Payment, and Fixed Fee incorporated
                    herein and made a part of this contract.  Payment of
                    fixed-fee shall not be made in less than monthly increments.
                   
             (c)    The Government's obligation, represented by the sum of the 
                    estimated cost plus fixed-fee, is $1,508,437.00.
                   
             (d)    Total funds currently available for payment and allotted 
                    to this contract are $490,973.00, of which $447,026.00
                    represents the estimated reimbursable costs, and $43,947.00
                    the fixed fee.  For further provisions on funding, refer to
                    the LIMITATION OF FUNDS clause.
                   
             (e)    It is estimated that the amount currently allotted will 
                    cover performance of work under the contract through 
                    November 30, 1994.
                   
             (f)    The Contracting Officer may allot additional funds to the 
                    contract without the concurrence of the Contractor.

                    DESCRIPTION/SPECIFICATION/WORK STATEMENT
                    ----------------------------------------

ARTICLE C.1  WORK STATEMENT
- ---------------------------

        (a)     Introduction:
                ------------

                The key objectives of the requested research effort are to
                speed up ongoing genetic research to obtain data critical for
                diagnosis, treatment and prevention of genetic neurological
                disorders.  The contractors will perform genetic research at
                the most labor-intensive, space- and time- consuming
                preparatory level.  This will enable the NINDS Sequencing
                facility, using highly efficient automated analysis, to extend
                these preliminary results.  Investigators could then be
                supplied with analyzed sequences, candidate disease gene loci
                from genetic typing, candidate exons from physical maps or
                candidate disease-specific mutations.
                
                The NINDS DNA sequencing facility is currently equipped with
                four ABI 373A DNA sequencers and ABI Catalyst robotic station
                for performing sequencing reactions.  Thirty six templates a
                day can be sequenced per sequencer.  The same sequencers can
                be used for automatic genetic typing and identification of
                unknown mutations using single-strand conformational
                polymorphism (SSCP) protocols.  The capacity of this Facility
                is very substantial and that places pressure on the other
                steps of the overall process, in particular the production of
                sequencing templates, carrying out sequencing reactions,
                marker selection for genetic typing, preparing and initial
                testing of genomic libraries, storage and analysis of data.
                
                This research is to improve and provide large scale DNA
                template production applicable to automated DNA sequence
                analysis.
                
        (b)     Technical Specifications:
                ------------------------

                Independently, and not as an agent of the Government, the
                contractor shall exert its best efforts to continue
                development of new and highly reproducible rapid DNA template
                production and purification procedures which provide DNA of
                sufficient purity for highly accurate automated DNA sequence
                analysis.  It is estimated that the Contractor will be
                required to provide approximately 10,000 purified DNA template
                preparations/year; genetic
                




                                     -8-

<PAGE>   10
                 typing in the amount of approximately 70 to 100 markers per
                 100 samples/year; and screening approximately 10 to 20
                 libraries/year.  The sources of DNA shall be provided to the
                 Contractor by the NINDS.

                 Specifically, the Contractor shall:

                 (1)    Carry out procedures for the creation of ordered 
                        deletions in large DNA fragments, develop new procedures
                        to facilitate the generation of such deletions in DNA
                        fragments of interest to the Government.  The goal is to
                        make in a given fragment overlapping deletions suitable
                        for sequencing by the use of the Applied Biosystems 373A
                        DNA Sequencer.  This shall require sets of deleted      
                        clones with each clone delete for about 300 bases
                        relativeto the next larger clone and about 100 base
                        overlap with the adjacent deletion clone.

                 (2)    Develop procedures to facilitate the preparation of
                        large numbers of DNA templates in order to provide
                        DNA sequence analysis of sufficient purity to permit
                        automated DNA sequence analysis of greater than 99%
                        accuracy over 400 bases/template.

                 (3)    Templates shall be prepared from a variety of 
                        substrates, including single strand phage DNA, double
                        strand plasmid  DNA, phagemid DNA, and genomic DNA as
                        necessary for a particular gene.  Sources of DNA may be
                        clonal bacterial cell-lines or phage supernants,
                        plasmids or bacteriophage, bacteriophage libraries, or
                        plasmid libraries.  In the case of phage libraries, the
                        library will be converted by the contractor to plasmid
                        form by in vivo excision.  Clones for template
                        preparation will be selected at random or after
                        screening with probes supplied by NIH that are designed
                        to eliminate undesirable clones.

                 (4)    The goals outlined in 1 and 2 (above) shall be
                        accomplished by utilizing a variety of procedures
                        depending upon the particular substrate being used. 
                        These procedures would include, but not be limited to,
                        polymerase chain reaction, PEG precipitation, cesium
                        chloride gradients, column chromatography and continuous
                        eluction gel electrophoresis, in an attempt to establish
                        the most rapid/cost effective and high quality procedure
                        for DNA template isolation and purification.

                 (5)    The contractor shall be required to produce 
                        approximately 10,000 DNA templates of sufficient
                        purity per year for automated DNA sequence analysis.

                 (6)    The contractor shall provide at least 20 micrograms of

                        phage infected cells, genomic DNA, plasmid DNA, phage
                        supernatants as deemed appropriate by the NINDS
                        Project Officer, based on the particular scientific
                        needs of the Government. The source of DNA will
                        usually be one of three classes which shall require
                        somewhat different processing by the Contractor.
                        Class one shall be human total genomic DNA which the
                        contractor shall use for genetic mapping. Class two
                        shall be YAC, cosmid or lambda clones containing
                        genomic DNA or plasmid clones containing cDNA which
                        the contractor shall use to subclone into a vector
                        suitable for ordered deletion generation, generate
                        ordered deletions and prepare templates for automated
                        sequencing. Class three shall be plasmid or phage
                        clones containing small inserts which the Contractor
                        shall amplify and purify and prepare for automated
                        sequencing. NINDS will provide instructions on the

         (b)      The Contractor agrees to use its best efforts to accomplish
                  all the work outlined or referenced under Article C.1. above.
                  Performance of the requirements under this Article will be
                  considered acceptable if the work is performed in accordance
                  with high standards of scientific and professional skills and
                  the indicated level of effort has been substantially applied,
                  provided, however, that all other requirements are met,
                  including delivery of reports and other materials as may be
                  required under the contract. Substantially applied means
                  delivery of at least 90% of the total labor hours specified.

         (c)      In the event fewer hours than that above are used by the
                  Contractor in accomplishing the work prescribed in Article
                  C.!., and the Government has not invoked its rights under FAR
                  Clause 52.249-6, Termination (Cost-Reimbursement),
                  incorporated in this contract the parties agree that the fee
                  will be adjusted based solely upon the quantity of hours by
                  which the number of hours furnished is less than the number of
                  hours specified in this Article. The resulting adjustment
                  shall be evidenced by a contract modification.

ARTICLE H.2  REIMBURSEMENT OF COSTS FOR INDEPENDENT RESEARCH AND DEVELOPMENT 
- ----------------------------------------------------------------------------
PROJECT
- -------

The primary purpose of the Public Health Service (PHS) is to support and
advance independent research within the scientific community.  This support is
provided in the form of contracts and grants totaling approximately 7 billion
dollars annually.  PHS has established effective, time tested and well
recognized procedures for stimulating and supporting this independent RESEARCH
by selecting from multitudes of applications those research projects most
worthy of support within the constraints of its appropriations.  The
reimbursement through the indirect cost mechanism of independent research and
development costs not incidental to product improvement would circumvent this
competitive process.

To ensure that all research and development projects receive similar and equal
consideration, all organizations may compete for direct funding of independent
research and development projects they consider worthy of support by submitting
those projects to the appropriate Public Health Service grant office for
review.   Since these projects may be submitted for direct funding, the
Contractor agrees that no costs for any independent research and development
project, including all applicable indirect costs, will be claimed under this
contract.

1.   EXPLANATION.
     -----------

     a.   These general terms and conditions do not restate all the provisions
          of applicable statutes and regulations, nor do they represent an
          exhaustive listing of all requirements applicable to this award.
          Rather, they highlight and are consistent with those requirements
          which are especially pertinent to research awards in general.  They
          are emphasized by inclusion here because:  (1) they are invoked with
          high frequency; (2) their violation is a matter of especially serious
          concern (e.g., use of human subjects); (3) restating them in the
          research context will allow them to be more easily understood by the
          research community.

     b.   In addition to these general terms and conditions, the recipient must
          comply with all governing requirements, including those identified in
          block 18 of DOE F 4600.1, "Notice of Financial Assistance Award," and
          those included in the "Special Terms and Conditions" attached to this
          award.

2.   RECIPIENT ADHERENCE TO THE TERMS AND CONDITIONS.
     -----------------------------------------------

     a.   The recipient's signature on the application and on DOE F 4600.1
          signifies the recipient's agreement to all terms and conditions of
          the award.  Should the recipient believe modification of any of the
          terms and conditions of this award is necessary, an authorized
          official of the recipient organization or, in the case of an
          individual, the recipient must submit a written request on its own
          behalf or on behalf of any subgrant recipient or applicant for prior
          approval of the contracting officer named on the face page of this
          award.

     b.   Following this procedure is very important because many of the terms
          and conditions of this award are required by statute and must be
          enforced by the Department of Energy.

3.   DEFINITIONS.
     -----------

     a.   PRINCIPAL INVESTIGATOR.  As used herein, the scientist or other
          programmatic expert named in block 8 of the DOE F 4600.1 designated
          by the recipient organization to direct the scientific/technical
          efforts being supported (also called program director or project
          director/leader).

     b.   PRIOR APPROVAL.  A statement in writing, signed by the contracting
          officer, that a cost may be incurred or an action may be taken.  The
          approval may take the form of a letter or a revision to the award.
          If actions or costs requiring prior approval are specified in the
          application and are not expressly disapproved by 




                                      -8-
<PAGE>   10

           DOE in the attached "Special Terms and Conditions," the award of
           the action constitutes such prior approval.

4.   AUTHORIZED RECIPIENT SIGNATURES FOR PRIOR APPROVAL REQUESTS.
     -----------------------------------------------------------
     All requests for prior approval must be signed by an individual who is
     authorized to act for the recipient organization.  The signature of the
     principal investigator (unless also a corporate office or otherwise
     authorized) is insufficient to obtain action on a prior approval request,
     although countersignature by the principal investigator is not
     discouraged.  Requests for budget revisions shall be made using the same
     budget format as used in applying for the award and must be supported by a
     narrative justification.  Other prior approval requests may be made by
     letter.  Prior approval requests should be addressed to the contracting
     officer named on the face page of this award.

5.   ALLOWABLE COSTS/APPLICABLE COST PRINCIPLES.
     ------------------------------------------

     a.   In accordance with the applicable cost principles cited below, the
          allowable costs of this award shall consist of the actual allowable
          direct costs incident to performance of the project, plus the
          allocable portion of the allowable indirect costs, if any, of the
          organization, less applicable credits.  The allowable costs shall not
          exceed the amount shown on the face page of this award for the total
          approved budget for the current budget period (line 16a.(6), DOE F
          4600.1, "Notice of Financial Assistance Award").

     b.   The allowability of costs for work performed under this award and any
          subsequent subaward will be determined in accordance with the Federal
          cost principles applicable to the recipient or subrecipient in effect
          on the date of award or the date of the subaward, except as modified
          by other provisions of this award or the subaward.  The recipient or
          subrecipient shall specify in any cost-reimbursement contract under
          the award or subaward the applicable cost principles cited in this
          provision that apply to the contractor.

     c.   The Federal cost principles applicable to specific types of
          recipients, subrecipients, and contractors under awards and subawards
          are as follows:

          (1)  INSTITUTIONS OF HIGHER EDUCATION.  Office of Management and
               Budget (OMB) Circular A-21, "Cost Principles Applicable to
               Grants, Contracts, and Other Agreements with Institutions of
               Higher Education," is applicable to both public and private
               colleges and universities.

          (2)  STATE AND LOCAL GOVERNMENTS AND INDIAN TRIBAL GOVERNMENTS.  OMB
               Circular A-87, "Cost Principles Applicable to Grants, Contracts
               and Other Agreements with State and Local Governments," is
               applicable to 


                                      -9-
<PAGE>   11
               State, local, and Indian tribal governments, and
               shall also be used to the extent appropriate for foreign
               governments.

          (3)  HOSPITALS.  Title 45 CFR Part 74, Appendix E, "Principles for
               Determining Costs Applicable to Research and Development under
               Grants and Contracts with Hospitals," applies to nonprofit and
               for-profit hospitals.

          (4)  OTHER NONPROFIT ORGANIZATIONS AND INDIVIDUALS.  OMB Circular
               A-122, "Cost Principles Applicable to Grants, Contracts, and
               Other Agreements with Nonprofit Organizations," applies to
               nonprofit organizations and individuals, except for those
               specifically exempted by the terms of the circular or those
               nonprofit organizations and individuals covered by the cost
               principles cited in paragraph 5.c.(1), (2), or (3) above.

          (5)  COMMERCIAL FIRMS AND CERTAIN NONPROFIT ORGANIZATIONS.  Title 48
               CFR Subpart 31.2, "Contracts with Commercial Organizations," as
               supplemented by 48 CFR Subpart 931.2, applies to those nonprofit
               organization not covered by OMB Circular A-122, and to all
               commercial organizations not covered by the cost principles in
               paragraph 5.c.(3).

6.   PAYMENT.
     -------

     a.   Payments under this award will be made by an advance payment method
          unless DOE determines that the recipient's financial management
          system does not meet the requirements of 10 CFR 600.109 or the
          recipient has not maintained or demonstrated the willingness and
          ability to maintain procedures that will minimize the time elapsing
          between transfer of funds from the U.S. Treasury and their
          disbursement for award-related purposes.

     b.   The appropriate advance payment method or the reimbursement method
          and the cognizant finance office are specified in the attached
          "Special Terms and Conditions."

     c.   Advances by the recipient to subrecipient and contractor
          organizations must conform substantially to the same standards of
          time and amount that govern advances made by the Federal Government
          to the recipient.  Excess cash advances erroneously withdrawn from
          the U.S. Treasury shall be promptly refunded to DOE unless the funds
          will be disbursed within 7 calendar days or the amount is less than
          $10,000 and will be disbursed within 30 calendar days.

     d.   Interest earned on advance payments to other than State governments
          or their subrecipients shall be reported on SF-272, "Report of
          Federal Cash 





                                      -10-
<PAGE>   12

          Transactions," and promptly remitted to the cognizant
          finance office by check payable to the Department of Energy (unless
          otherwise specified in the attached "Special Terms and Conditions").

7.   PREAWARD COSTS.
     --------------

     a.   ALL AWARDS.  Any preaward expenditures are made at the recipient's
          risk.  Approval of preaward costs by the Contracting Officer or
          incurrence by the recipient does not impose any obligation on DOE if
          an award is not subsequently made, or if an award is made for a
          lesser amount than the recipient expected.

     b.   RESEARCH AWARDS ONLY.
          --------------------

          (1)  For new or renewal research awards, recipients may incur
               preaward costs up to ninety (90) days prior to the effective
               date of the award.  Preaward costs for periods preceding 90 days
               prior to the effective date of the award are allowable only if
               approved in writing, prior to incurrence, by a DOE Contracting
               Officer.

          (2)  For continuation awards within a multiple year project, prior to
               receipt of continuation funding, preaward expenditures by
               recipients are not subject to the limitation or approval
               requirements of paragraph 7.b.(1) of this section.

          (3)  Preaward costs, as incurred by the recipient, must be necessary
               for the effective and economical conduct of the project, and the
               costs must be otherwise in accordance with these rules and may
               not include those specific costs for which agency prior approval
               is required under the circulars.  In any instance in which the
               circulars permit the agency to grant prior approval to the
               recipient, it is the Department's intention to do so.

     c.   OTHER THAN RESEARCH AWARDS.  All other financial assistance
          recipients may incur preaward costs only if the expenditure is
          approved in writing, prior to incurrence, by the Contracting Officer.
          In the case of governmental entities, the approval must additionally
          be reflected on the award notice.

     (Note:  This provision does not apply to bid and proposal costs that may
     be recovered through an indirect cost rate negotiated in accordance with
     the applicable Federal cost principles.)

8.   REPORTING REQUIREMENTS.
     ----------------------

     a.   Attached to the award is a completed EIA 459A, "Federal Assistance
          Reporting Checklist," a checklist of the reports required under the
          award.  (See 10 CFR 600.115 for general reporting requirements and 10
          CFR 605.19 for reporting requirements for the Office of Energy
          Research's Special Research Financial Assistance Program.)

     b.   The recipient shall submit a technical progress report (also called a
          performance report) as part of any application for continuation or
          renewal of DOE support.  This report shall be submitted in lieu of a
          separate annual performance report.  Upon completion or termination
          of the project, the final technical report shall be prepared in
          accordance with the applicable program rule cited on the face page of
          the award or, in the absence of such program rule coverage, in
          accordance with the technical reporting format specified in DOE Order
          1332.2, the UNIFORM REPORTING SYSTEM FOR FEDERAL ASSISTANCE (GRANTS
          AND COOPERATIVE AGREEMENTS).

     c.   Instructions concerning financial reports to be submitted in
          conjunction with this award are specified in the "Special Terms and
          Conditions."

9.   COST SHARING.
     ------------

     a.   As shown on the face page of the award, any cost sharing shall defray
          only the allowable costs of the project in accordance with the
          statutes, regulations, applicable cost principles, and other terms
          and conditions governing the award.  Cost sharing contributions may
          be incurred either as direct or indirect costs, and include cash or
          in-kind contributions by the recipient, its subrecipients, or
          contractors.  The cost sharing may be in any allowable budget
          category or combination of categories.  When a direct cost item
          represents some or all of the non-Federal contribution, any
          associated indirect costs may not be charged to Federal funds but may
          be counted as part of the cost sharing.  The classification of
          contributed costs as direct or indirect must be consistent with the
          classification of similar items charged to DOE funds.

     b.   Valuation of in-kind contributions and documentation of cost sharing
          shall be in accordance with 10 CFR 600.107.

10.  CONTINUATIONS, RENEWALS, AND EXTENSIONS.
     ---------------------------------------

     a.   Continuations.  Recipients are responsible for ensuring that properly
          completed applications for continuation awards are submitted to DOE
          no later than 3 months prior to the expiration date of the current
          budget period shown on the 


                                      -12-
<PAGE>   14
          DOE F 4600.1.  (For the continuation of an
          action which had been awarded under the Office of Energy Research's
          Financial Assistance Program in accordance with 10 CFR Part 605, an
          application for a continuation award must be submitted to DOE no
          later than 3 months before the expiration of the current budget
          period.)

     b.   RENEWALS.  If a recipient wishes to apply for a renewal award to
          receive funding beyond the scheduled expiration of the existing
          project period, a properly completed application must be submitted to
          DOE no later than 5 months prior to the scheduled expiration date of
          the project period as shown on the DOE F 4600.1 unless a program rule
          or other published instruction establishes a different application
          deadline.  (For the renewal of an action which had been awarded under
          the Office of Energy Research's Financial Assistance Grants Program
          in accordance with 10 CFR Part 605, an application for a renewal
          award must be submitted to DOE no later than 6 months prior to the
          scheduled expiration of the project period.)

     c.   EXTENSIONS.  (1) Recipients of research awards may extend the
          expiration date of the final budget period of the project (thereby
          extending the project period) if additional time beyond the
          established expiration date is needed to assure adequate completion
          of the original scope of work within the funds already made
          available.  A single extension, which shall not exceed twelve (12)
          months, may be made for this purpose, and must be made prior to the
          originally established expiration date.  The recipient must notify
          the cognizant DOE Contracting Officer in the awarding office in
          writing within ten (10) days of making the extension.  (2) DOE may
          extend any budget period of any type of financial assistance without
          the need for competition or a justification of restricted eligibility
          if:  (i) In the case of the final budget period of a project period,
          the additional time necessary is 18 months or less in total, or for
          all other budget periods, the additional time necessary is 6 months
          or less in total; and (ii) The recipient submits a written request
          for an extension before the expiration date of the budget period in
          process and includes a justification for the extension along with an
          expenditure plan for the use of any additional funds requested.  An
          expenditure plan need not be provided when no additional funds are
          requested, unless the recipient intends to rebudget funds in such a
          way as to require DOE prior approval or unless the recipient is
          instructed otherwise by the Contracting Officer.

11.  MAXIMUM DEPARTMENT OBLIGATION to the recipient is the amount shown on the
     DOE F 4600.1.  DOE shall not be obligated to make any additional,
     supplemental, continuation, renewal, or other award for the same or any
     other purpose.

12.  TRANSFERS OF FUNDS BETWEEN FINANCIAL ASSISTANCE INSTRUMENTS.
     -----------------------------------------------------------
     Transfers of funds between DOE awards, and transfers of funds from a DOE
     award to a project (or portion of a project) not supported by that award,
     require the prior approval of DOE.  The transfer of funds into a DOE
     award-supported project from a award awarded by another Federal agency
     does not require DOE approval, but may require the approval of the other
     Federal agency.  Funds so transferred from the award of another Federal
     agency may not be used to satisfy any cost sharing requirement on a DOE
     award.

13.  PROPERTY.
     --------

     a.   REAL AND TANGIBLE PERSONAL PROPERTY.
          -----------------------------------

          (1)  No real property may be acquired under this award.

          (2)  Title to any equipment (for the purposes of DOE awards,
               equipment comprises any article of tangible personal property
               that has a useful life of more than 2 years and an acquisition
               cost of $500 or more) or supplies acquired by a nonprofit
               institution of higher education or a nonprofit organization, the
               primary purpose of which is to conduct scientific research,
               shall vest in the recipient without further obligation or
               accountability to the U.S. Government.  However, DOE retains the
               right to transfer ownership of any item of equipment having a
               unit acquisition cost of $1,000 or more under the conditions
               specified in 10 CFR 600.117(d)(2).  This exemption is derived
               from Public Law 95-224, The Federal Grant and Cooperative
               Agreement Act of 1977, as amended (31 U.S.C. 6306).

          (3)  Title to equipment and supplies acquired by all other recipients
               shall vest in the recipient.  However, such recipients shall be
               accountable for equipment with a unit acquisition cost of $1,000
               or more acquired under this award as specified in 10 CFR
               600.117(d)(2), (3), and (4).  For such recipients, unused
               supplies exceeding $1,000 in aggregate current fair market value
               shall be accounted for at closeout.  In this case DOE shall be
               compensated in an amount computed in accordance with section
               600.117(e) if the supplies are retained for use on non-Federal
               activities.

          (4)  All recipients shall follow property management policies and
               procedures that provide for adequate control of the acquisition
               and use of the assets acquired under the award.

          (5)  The Contracting Officer by written notice to the Recipient, may
               abandon any property, title to which is vested in the
               Government, in place, and 



                                      -14-
<PAGE>   16
                thereafter all obligations of the Government regarding such
                abandoned property shall cease.

     b.   INTANGIBLE PROPERTY.  The treatment and reporting requirements of
          patent and data rights and copyrights are specified in the "Special
          Terms and Conditions" of the award.

14.   CHANGE OR ABSENCE OF THE PRINCIPAL INVESTIGATOR OR DESIGNATED KEY
      PERSONNEL.  Since the DOE decision to fund a project is based, to a
      significant extent, on the qualifications and level of participation of
      the principal investigator, change of a principal investigator or a
      significant change in responsibilities or level of effort of the principal
      investigator or, in certain cases, other key personnel identified as such
      in the special terms and conditions of the award is considered a change in
      the approved project.  In addition, any continuous absence of the
      principal investigator in excess of three months, or plans for the
      principal investigator to become substantially less involved in the
      project than was indicated in the application as accepted, requires
      approval.  The recipient is encouraged to contact DOE immediately upon
      becoming aware that any of these changes are likely to be proposed, but in
      any event must do so and receive Departmental approval before effecting
      any such change.

15.   CHANGES IN OBJECTIVES OR SCOPE. Any change in the objective or scope of
      the award-supported project requires the prior approval of DOE.  This
      includes changes in the phenomenon or phenomena under study and in the
      methodologies or experiments if they are a specific objective of the
      research work as stated in the application approved by DOE.

16.   TRANSFER OF SUBSTANTIVE PROGRAMMATIC EFFORT. None of the substantive
      effort of the project may be transferred by contract or subgrant to
      another organization or person without the prior approval of DOE.  This
      provision does not apply to the procurement of equipment, supplies,
      materials, or general support services; these services may, however, be
      subject to other prior approval requirements (e.g., those found in the
      applicable cost principles or procurement standards).

17.   CONSULTANT SERVICES.  Costs of consultant services are allowable in
      accordance with the applicable cost principles.  These principles include
      the requirement that the consultant not be an employee of the recipient
      organization; the one exception to this requirement applies to colleges
      and universities.  For colleges and universities, in unusual cases, and
      only with the prior approval of DOE, intraorganizational consultation may
      be permitted across departmental lines or at a separate or remote
      operation.

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

     a.   The award is subject to the requirements of the Paperwork Reduction
          Act of 1980 as implemented by the Office of Management and Budget
          rules, "Controlling Paperwork Burdens on the Public," published at 5
          CFR 1320 (48 FR 13666, 3-31-83).  These requirements apply if the
          recipient will collect information from ten or more respondents at
          the specific request of DOE, or if the award requires specific DOE
          approval of the information collection or the collection procedures.

     b.   The recipient shall submit any proposed sponsored information
          collection under paragraph 19a, above, to the contracting officer
          named on the face page of this award.  The proposal shall be
          submitted at least 120 days prior to the intended date of information
          collection.  DOE will seek the requisite approval from the Office of
          Management and Budget and will promptly notify the recipient of the
          disposition of the request.

19.  GENERALLY APPLICABLE REQUIREMENTS.  In accordance with 10 CFR 600.12, this
     award is subject to a number of statutory and other generally applicable
     requirements.  Those requirements most pertinent to research projects are
     highlighted below:

     a.   Any recipient performing research on vertebrate animals shall comply
          with the Laboratory Animal Welfare Act of 1966, as amended (7 USC
          2131 ET SEQ.), and the regulations promulgated thereunder by the
          Secretary of Agriculture (9 CFR subchapter A, parts 1, 2, 3, and 4)
          pertaining to the care, handling, and treatment of vertebrate animals
          held or used for research, teaching, or other activities supported by
          Federal awards.  The recipient is expected to ensure that the
          guidelines described in Department of Health and Human Services
          (DHHS) Publication No. (NIH) 85-23, "Guide for the Care and Use of
          Laboratory Animals," are followed and to comply with the "U.S.
          Government Principles for the Utilization and Care of Vertebrate
          Animals Used in Testing, Research and Training" (included as an
          Appendix to the NIH Guide).

     b.   RESEARCH INVOLVING RECOMBINANT DNA MOLECULES.  Any recipient
          performing research involving recombinant DNA molecules and/or
          organisms and viruses containing recombinant DNA molecules agrees by
          acceptance of this award to comply with the National Institute's of
          Health "Guidelines for Research Involving Recombinant DNA Molecules,"
          6-83 (48 FR 24556) or such later revision of those guidelines as may
          be published in the FEDERAL REGISTER.

     c.   USE OF HUMAN SUBJECTS IN RESEARCH, DEVELOPMENT, AND RELATED
          ACTIVITIES.  Any DOE recipient performing research, development, or
          related activities involving 


                                      -16-
<PAGE>   18

          human subjects must comply with regulations found at 10 CFR Part 745,
          "Protection of Human Subjects," and any additional provisions which
          may be included in the "Special Terms and Conditions" of the award.
          Such provisions are intended to safeguard the rights and welfare of
          human subjects at risk of possible physical, psychological, or social
          injury as a consequence of their participation.

20.  NONDISCRIMINATION.  The award is subject to the provisions of 10 CFR 1040,
     Nondiscrimination in Federally Assisted Programs.

21.  PUBLIC ACCESS TO INFORMATION.
     ----------------------------

     a.   The Freedom of Information Act, as amended, and the DOE implementing
          regulations (10 CFR 1004) require DOE to release certain documents
          and records regarding awards to any person who provides a written
          request.  The intended use of the information will not be a criterion
          for release.  These requirements apply to information held by DOE and
          do not require recipients, their subrecipients, or their contractors
          to permit public access to their records.

     b.   Records maintained by DOE with respect to awards are subject to the
          provisions of the Privacy Act and the DOE implementing regulations
          (10 CFR 1008) if those records constitute a "system of records" as
          defined in the Act and the regulations.  Generally, records
          maintained by recipients, their subrecipients, or their contractors
          are not subject to these requirements.

22.  ACKNOWLEDGMENT OF SUPPORT.  Publication of the results of the award is
     encouraged subject to any applicable restrictions in 10 CFR 600.33
     (Patents, Data, and Copyrights).  Any article published shall include an
     acknowledgment that the research was supported, in whole or in part, by a
     DOE award (with the award number) and a statement that such support does
     not constitute an endorsement by DOE of the views expressed in the
     article.

23.  NATIONAL SECURITY.
     -----------------

     a.   It is not expected that activities under the award will generate or
          otherwise involve classified information (i.e., Restricted Data,
          Formerly Restricted Data, National Security Information).

     b.   However, if in the opinion of the recipient or DOE such involvement
          becomes expected prior to the closeout of the award, the recipient or
          DOE shall notify the other in writing immediately.  If the recipient
          believes any information developed or acquired may be classifiable,
          the recipient shall not provide the potentially classifiable
          information to anyone, including the DOE officials with 


                                      -17-
<PAGE>   19
          
          whom the recipient normally communicates, except the Director of
          Classification, and shall protect such information as if it were
          classified until notified by DOE that a determination has been made
          that it does not require such handling.  Correspondence which includes
          the specific information in question shall be sent by registered mail
          to U.S. Department of Energy, ATTN: Director of Classification, DP-32,
          Washington, DC 20545.  If the information is determined to be
          classified, the recipient may wish to discontinue the project, in
          which case the recipient and DOE shall terminate the award by mutual
          agreement.  If the award is to be terminated, all material deemed by
          DOE to be classified shall be forwarded to DOE, in a manner specified
          by DOE, for proper disposition.  If the recipient and DOE wish to
          continue the award, even though classified information is involved,
          the recipient shall be required to obtain both personnel and facility
          security clearances through the Office of Safeguards and Security for
          Headquarters awarded awards or from the cognizant field office
          Division of Safeguards and Security for awards obtained through DOE
          field organizations.  Costs associated with handling and protecting
          any such classified information shall be negotiated at the time the
          determination to proceed is made.


24.  SUSPENSIONS AND TERMINATIONS.
     ----------------------------

     a.   Under the provisions of 10 CFR 600.29 and 600.121, DOE may suspend or
          terminate the award, in whole or in part, (1) when DOE believes that
          the recipient has materially failed to comply with the terms and
          conditions of the award, (2) for any reason by mutual agreement
          between DOE and the recipient upon the request of either party, or
          (3) when the parties cannot mutually agree to the extent of a
          termination.

     b.   Normally, DOE action to suspend or terminate an award for cause will
          be taken only after DOE has informed the recipient of any deficiency
          on its part and given an opportunity to correct it.  However, DOE may
          immediately suspend or terminate the award without prior notice when
          it believes such action is necessary to protect the interests of the
          Government.

     c.   No costs incurred during a suspension period or after the effective
          date of a termination will be allowable, except those costs which, in
          the opinion of DOE, the recipient could not reasonably avoid or
          eliminate or which were otherwise authorized by the suspension or
          termination notice, provided such costs would otherwise be allowable
          under the terms of the award and the applicable Federal cost
          principles.

     d.   Final allowable costs under a termination settlement shall be in
          accordance with the terms of the award, including this term, and the
          appropriate Federal cost 



                                      -18-
<PAGE>   20

          principles.  In no event will the total of payments under a terminated
          award exceed the amount obligated by DOE or the DOE PRO RATA share
          when cost-sharing was required, whichever is less.

     e.   Within 90 days after the termination of the award, the recipient
          shall submit any final financial, performance, and other reports
          required by the terms and conditions of the award.  (See 10 CFR
          600.115 and 600.116).

     f.   A notice of termination other than by mutual agreement may be subject
          to review according to the provisions of 10 CFR 600.26, Disputes and
          Appeals.

25.  INTEREST.
     --------

     a.   Notwithstanding any other term or condition of the grant/cooperative
          agreement, all amounts that become payable by the recipient to the
          Government under the grant/cooperative agreement shall bear simple
          interest from the date due until paid unless paid within 30 days of
          becoming due.  The interest rate shall be the interest rate
          established by the Secretary of the Treasury (Secretary) as provided
          in section 11 of the Debt Collection Act of 1982 (31 U.S.C. 3717),
          which is applicable to the period in which the amount becomes due, as
          provided in paragraph (b) below, and then at the rate applicable for
          each 3-month period as fixed by the Secretary until the amount is
          paid.

     b.   Amounts shall be due at the earliest of the following dates:

          (1)  The date fixed under the grant/cooperative agreement.

          (2)  The date of the first written demand for payment consistent with
               the grant/cooperative agreement, including any demand resulting
               from a termination.

          (3)  The date the Government transmits to the recipient a proposed
               agreement to confirm completed negotiations establishing the
               amount of debt.

     c.   The interest charge made under this provision may be reduced in
          accordance with the procedures prescribed in 4 CFR 102.13 or in
          accordance with agency regulations in effect on the date of original
          award of the grant/cooperative agreement.

26.  FOREIGN TRAVEL.
     -------------- 


                                      -19-
<PAGE>   21

     Foreign travel is any travel outside Canada and the United States and its
     territories and possessions or, for recipients located in another country,
     travel outside that country.  The International Air Transportation Fair
     Competitive Practices Act of 1974 (49 USC 1517) (Fly America Act) requires
     Federal recipients to use U.S. flag carriers for Government-financed
     international air travel to the extent these carriers are available.
     Recipients contemplating the use of non-U.S. flag carriers should consult
     with the DOE contracting officer prior to the trip.

27.  FINANCIAL ASSISTANCE AWARDS TO INDIVIDUALS

     Any financial assistance award to an individual is considered a "Federal
     benefit" as defined by Section 5301 of the Anti-Drug Abuse Act of 1988
     (Public Law 100-690) and is therefore subject to the provisions of that
     act.

ARTICLE 1.     AUTHORIZATION AND CONSENT

The Government hereby gives its authorization and consent for all use and
manufacture of any invention described in and covered by a patent of the United
States in the performance of this grant or any part hereof or any amendment
hereto or any contract hereunder (including all lower-tier contracts
hereunder).

ARTICLE 2.     NOTICE AND ASSISTANCE REGARDING PATENT AND COPYRIGHT
               INFRINGEMENT

The provisions of this clause shall be applicable only if the amount of this
grant exceeds $10,000.

  (a)     The Grantee shall report to the Contracting Officer, promptly and in
          reasonable written detail, each notice or claim of patent or
          copyright infringement based on the performance of this grant of
          which the Grantee has knowledge.

  (b)     In the event of any claim or suit against the Government on account
          of any alleged patent or copyright infringement arising out of the
          performance of this grant or out of the use of any supplies furnished
          or work or services performed hereunder, the Grantee shall furnish to
          the Government when requested by the Contracting Officer, all
          evidence and information in possession of the Grantee pertaining to

     (1)  The Grantee may retain the entire right, title, and interest
          throughout the world to each subject invention subject to the
          provisions of this clause and 35 U.S.C. 203.  With respect to any
          subject invention in which the Grantee retains title, the Federal
          Government shall have a nonexclusive, nontransferable, irrevocable,
          paid-up license to practice or have practiced for or on behalf of the
          United States the subject invention throughout the world.

     (2)  (Reserved.)

(c)     Invention Disclosure, Election of Title and Filing of Patent
        ------------------------------------------------------------
        Application by Grantee
        ----------------------

     (1)  The Grantee will disclose each subject invention to the Patent
          Counsel within two months after the inventor discloses it in writing
          to Grantee personnel responsible for patent matters.  The disclosure
          to the Patent Counsel shall be in the form of a written report and
          shall identify the grant under which the invention was made and the
          inventor(s).  It shall be sufficiently complete in technical detail
          to convey a clear understanding to the extent known at the time of
          the disclosure of the nature, purpose, operation, and the physical,
          chemical, biological or electrical characteristics of the invention.
          The disclosure shall also identify any publication, on sale or public
          use of the invention and whether a manuscript describing the
          invention has been submitted for publication and, if so, whether it
          has been accepted for publication at the time of disclosure.  In
          addition, after disclosure to the Patent Counsel, the Grantee will
          promptly notify the Patent Counsel of the acceptance of any
          manuscript describing the invention for publication or of any on sale
          or public use planned by the Grantee.

     (2)  The Grantee will elect in writing whether or not to retain title to
          any such invention by notifying the Patent Counsel within two years
          of disclosure to the Patent Counsel.  However, in any case where
          publication, on sale or public use has initiated the one year
          statutory period wherein valid patent protection can still be
          obtained in the United States, the period for election of title may
          be 

                                      -28-
<PAGE>   30

          shortened by Patent Counsel to a date that is no more than sixty
          days prior to the end of the statutory period.

     (3)  The Grantee will file its initial patent application on a subject
          invention to which it elects to retain title within one year after
          election of title or, if earlier, prior to the end of any statutory
          period wherein valid patent protection can be obtained in the United
          States after a publication, on sale, or public use.  The Grantee will
          file patent applications in additional countries or international
          patent offices within either ten months of corresponding initial
          patent application or six months from the date permission is granted
          by the Commissioner of Patents and Trademarks to file foreign patent
          applications where such filing has been prohibited by a Secrecy
          Order.

     (4)  Request for extension of the time for disclosure to the Patent
          Counsel, election, and filing, under subparagraphs (1), (2), and (3)
          may, at the discretion of the Patent Counsel by granted.

  (d)     Conditions When the Government May Obtain Title
          -----------------------------------------------

The Grantee will convey to DOE, upon written request, title to any subject
invention:

     (1)  If the Grantee fails to disclose or elect title to the subject
          invention within the times specified in (c) above, or elects not to
          retain title; provided that the DOE may only request title within 60
          days after learning of the failure of the grantee to disclose or
          elect within the specified times;

     (2)  In those countries in which the Grantee fails to file patent
          applications within the times specified in (c) above; provided,
          however, that if the Grantee has filed a patent application in a
          country after the time specified in (c) above but prior to its
          receipt of the written request of the Patent Counsel, the Grantee
          shall continue to retain title in that country; or

     (3)  In any country in which the Grantee decides not to continue the
          prosecution of any application for, to pay the maintenance fees on,
          or defend in a reexamination or opposition proceeding on, a patent on
          a subject invention.

  (e)     Minimum Rights to Grantee and Protection of the Grantee Right to File
          ---------------------------------------------------------------------

     (1)  The Grantee will retain a nonexclusive, royalty-free license
          throughout the world in each subject invention to which the
          Government obtains title except if the Grantee fails to disclose the
          subject invention within the times specified in (c) above.  The
          Grantee's license extends to its domestic subsidiaries and
          affiliates, if any, within the corporate structure of which the
          Grantee is a part and includes the right to grant sublicenses of the
          same scope to the extent the Grantee was legally obligated to do so
          at the time the grant was awarded.  The license is transferable only
          with the approval of the DOE except when transferred to the successor
          of that part of the Grantee's business to which the invention
          pertains.

     (2)  The Grantee's domestic license may be revoked or modified by DOE to
          the extent necessary to achieve expeditious practical application of
          the subject invention pursuant to an application for an exclusive
          license submitted in accordance with applicable provisions at 37 CFR
          404 and 10 CFR 781.  This license will not be revoked in that field
          of use or the geographical areas in which the Grantee has achieved
          practical application and continues to make the benefits of the
          invention reasonably accessible to the public.  The license in any
          foreign country may be revoked or modified at the discretion of DOE
          to the extent that Grantee, its licensees, or its domestic
          subsidiaries or affiliates have failed to achieve practical
          application in that foreign country.

                                      -29-
<PAGE>   31

     (3)  Before revocation or modification of the license, DOE will furnish
          the Grantee a written notice of its intention to revoke or modify the
          license, and the Grantee will be allowed thirty days (or such other
          time as may be authorized by DOE for good cause shown by the Grantee)
          after the notice to show cause why the license should not be revoked
          or modified.  The Grantee has the right to appeal, in accordance with
          37 CFR 404 and 10 CFR Part 781, any decision concerning the
          revocation or modification of its license.

  (f)     Grantee Action to Protect Government's Interest
          -----------------------------------------------

     (1)  The Grantee agrees to execute or to have executed and promptly
          deliver to the Patent Counsel all instruments necessary to:

           (i) Establish or confirm the rights the Government has throughout
               the world in those subject inventions to which the Grantee
               elects to retains title, and

          (ii) Convey title to DOE when requested under (d) above and to enable
               the Government to obtain patent protection throughout the world
               in that subject invention.

     (2)  The Grantee agrees to require, by written agreement, its employees,
          other than clerical and nontechnical employees, to disclose promptly
          in writing to personnel identified as responsible for the
          administration of patent matters and in a format suggested by the
          Grantee each subject invention made under this grant in order that
          the Grantee can comply with the disclosure provision of (c) above and
          to execute all papers necessary to file patent applications on
          subject inventions and to establish the Government's rights in the
          subject inventions.  The disclosure format should require, as a
          minimum, the information requested by subparagraph (c)(1) above.  The
          Grantee shall instruct such employees through the employee agreements
          or suitable educational programs on the importance of reporting
          inventions in sufficient time to permit the filing of patent
          applications prior to United States or foreign statutory bars.

     (3)  The Grantee will notify the Patent Counsel of any decision not to
          continue prosecution of a patent application, pay maintenance fees,
          or defend in a reexamination or opposition proceeding on a patent, in
          any country, not less than thirty days before the expiration of the
          response period required by the relevant patent office.

     (4)  The Grantee agrees to include, within the specification of any United
          States patent applications and any patent issuing thereon covering a
          subject invention, the following statement, "This invention was made
          with Government support under (identify the grant) awarded by the
          Department of Energy.  The Government has certain rights in this
          invention."

     (5)  The Grantee agrees to:

          (i)  Upon request, provide a report to the close-out of the grant
               listing all subject inventions or stating that there were none;

          (ii) Provide, upon request, a copy of the patent application, filing
               date, serial number and title, patent number and issue date for
               any subject invention in any country in which the grantee has
               applied for a patent; and

         (iii) Provide, upon request, but not more than annually, listings
               of all subject inventions which were disclosed to DOE
               during the applicable reporting period.

                                      -30-
<PAGE>   32

  (g)     Contracts and Subgrants under the Grant
          ---------------------------------------

     (1)  The Grantee will include this clause, suitably modified to identify
          the parties, in all contracts and subgrants under the grant,
          regardless of tier, for experimental, developmental, or research work
          to be performed by a small business firm or a domestic nonprofit
          organization.  The contractor or subgrantee will retain all rights
          provided for the Grantee in this clause, and the Grantee will not, as
          part of the consideration for awarding the contract or subgrant,
          obtain rights in the contractor's or subgrantee's subject inventions.

     (2)  The Grantee will include in all other contracts or subgrants under
          the grant, regardless of tier, for experimental, developmental,
          demonstration, or research work the patent rights clause required of
          41 CFR 9-9.107-5(a) or 9-9.107-6, as appropriate, modified to
          identify the parties.

     (3)  In the case of contract or subgrant under the grant at any tier, DOE,
          the contractor or subgrantee, and the Grantee agree that the mutual
          obligations of the parties created by this clause constitute a
          contract between the contractor or subgrantee and DOE with respect to
          those matters covered by this clause.

  (h)     Reporting on Utilization of Subject Inventions
          ----------------------------------------------

The Grantee agrees to submit on request periodic reports no more frequently
than annually on the utilization of a subject invention or on efforts at
obtaining such utilization that are being made by the Grantee or its licensees
or assignees.  Such reports shall include information regarding the status of
development, date of first commercial sale or use, gross royalties received by
the Grantee, and such other data and information as DOE may reasonably specify.
The Grantee also agrees to provide additional reports as may be requested by
DOE in connection with any march-in proceeding undertaken by DOE in accordance
with paragraph (j) of this clause.  As required by 35 U.S.C. 202(c)(5), DOE
agrees it will not disclose such information to persons outside the Government
without permission of the Grantee.

  (i)     Preference for United States Industry
          -------------------------------------

Notwithstanding any other provision of this clause, the Grantee agrees that
neither it nor any assignee will grant to any person the exclusive right to use
or sell any subject inventions in the United States unless such person agrees
that any products embodying the subject invention or produced through the use
of the subject invention will be manufactured substantially in the United
States.  However, in individual cases, the requirement for such an agreement
may be waived by DOE upon a showing by the Grantee or its assignee that
reasonable but unsuccessful efforts have been made to grant licenses on similar
terms to potential licensees that would be likely to manufacture substantially
in the United States or that under the circumstances domestic manufacture is
not commercially feasible.

  (j)     March-in Rights
          ---------------

The Grantee agrees that with respect to any subject invention in which it has
acquired title, DOE has the right in accordance with the procedures in 37 CFR
401.6 and any supplemental regulations of DOE to require the Grantee, as
assignee or exclusive licensee of a subject invention to grant a nonexclusive,
partially exclusive, or exclusive license in any field of use to a responsible
applicant or applicants, upon terms that are reasonable under the
circumstances, and if the Grantee, assignee, or exclusive licensee refuses such
a request, DOE has the right to grant such a license itself if DOE determines
that:

                                      -31-
<PAGE>   33

     (1)  Such action is necessary because the Grantee or assignee has not
          taken, or is not expected to take within a reasonable time, effective
          steps to achieve practical application of the subject invention in
          such field of use;

     (2)  Such action is necessary to alleviate health or safety needs which
          are not reasonably satisfied by the Grantee, assignee, or their
          licensees;

     (3)  Such action is necessary to meet requirements for public use
          specified by federal regulations and such requirements are not
          reasonably satisfied by the Grantee, assignee, or licensees; or

     (4)  Such action is necessary because the agreement required by paragraph
          (i) of this clause has not been obtained or waived or because a
          licensee of the exclusive right to use or sell any subject invention
          in the United States is in breach of such agreement.

  (k)     Special Provisions for Grants with Nonprofit Organizations
          ----------------------------------------------------------

If the Grantee is a non-profit organization, it agrees that:

     (1)  Rights to a subject invention in the United States may not be
          assigned without the approval of DOE, except where such assignment is
          made to an organization which has as one of its primary functions the
          management of inventions, provided that such assignee will be subject
          to the same provisions as the grant;

     (2)  The Grantee will share royalties collected on a subject invention
          with the inventor, including Federal employee co-inventors (when DOE
          deems it appropriate) when the subject invention is assigned in
          accordance with 35 U.S.C. 202(e) and 37 CFR 401.10;

     (3)  The balance of any royalties or income earned by the Grantee with
          respect to subject inventions, after payment of expenses (including
          payments to inventors) incidental to the administration of subject
          inventions, will be utilized for the support of scientific research
          or education; and

     (4)  It will make efforts that are reasonable under the circumstances to
          attract licensees of subject inventions that are small business firms
          and that it will give a preference to a small business firm when
          licensing a subject invention if the Grantee determines that the
          small business firm has a plan or proposal for marketing the
          invention which, if executed, is equally as likely to bring the
          invention to practical application as any plans or proposals from
          applications that are not small business firms; provided that the
          Grantee its also satisfied that the small business firm has the
          capability and resources to carry out is plan or proposal.  The
          decision whether to give a preference in any specific case will be at
          the discretion of the Grantee.  However, the Grantee agrees that the
          Secretary of Commerce may review the Grantee's licensing program and
          decisions regarding small business applicants, and the Grantee will
          negotiate changes to its licensing policies, procedures, or practices
          with the Secretary of Commerce when the Secretary of Commerce's
          review discloses that the Grantee could take reasonable steps to
          implement more effectively the requirements of this paragraph (k)(4).

  (l)     Communications
          --------------
The DOE central point of contact for communications or matters relating to this
clause is the Patent Counsel.

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

     (1)  The Government shall have:

          (i)  Unlimited rights in grant data except as otherwise provided
               below with respect to proprietary data.

         (ii)  The right to remove, cancel, correct or ignore any markings not
               authorized by the terms of this grant of any technical data
               furnished hereunder, if in response to a written inquiry by DOE
               concerning the propriety of the markings, the Grantee fails to
               respond thereto within 60 days or fails to substantiate the
               proprietary of the markings.  In either case DOE will notify the
               Grantee of the action taken.

        (iii)  No rights under this grant in any technical data which are
               not grant data.

     (2)  The Grantee shall have:

          (i)  The right to withhold proprietary data in accordance with the
               provisions of this article, and

         (ii)  The right to use for its private purposes, subject to patent,
               security or other provisions of this grant, grant data it first
               produces in the performance of this grant provided the data
               requirements of this grant have been met as of the date of the
               private use of such data.  The Grantee agrees that to the extent
               it receives or is given access to proprietary data or other
               technical, business or financial data in the form of recorded
               information from DOE or a DOE grant, contract or subcontractor,
               the Grantee shall treat such data in accordance with any
               restrictive legend contained thereon, unless use is specifically
               authorized by prior written approval of the Contracting Officer.

     (3)  Nothing contained in this "Rights in Technical Data" article shall
          imply a license to the Government under any patent or be construed as
          affecting the scope of any license or other rights otherwise granted
          to the Government under any patent.

  (c)     Copyrighted Material
          --------------------

     (1)  The Grantee shall not, without prior written authorization of the
          Contracting Officer, establish a claim to statutory copyright in any
          grant data first produced in the performance of the grant.  To the
          extent such authorization is granted, the Government reserves for
          itself and others acting on its behalf a royalty-free, nonexclusive,
          irrevocable, world-wide license for Governmental purposes to publish,
          distribute, translate, duplicate, exhibit and perform any such data
          copyrighted by the Grantee.

     (2)  The Grantee agrees not to include in the technical data delivered
          under the grant any material copyrighted by the Grantee and not to
          knowingly include any material copyrighted by others without first
          granting or obtaining at no cost a license therein for the benefit of
          the Government of the same scope as set forth in paragraph (c)(1)
          above.  If such royalty-free license is unavailable and the Grantee
          nevertheless determines that such copyrighted material must be
          included in the technical data to be delivered, rather than merely
          incorporated therein by 

                                      -34-
<PAGE>   36

          reference, the Grantee shall request the written authorization of the
          Contracting Officer to include such copyrighted material in the
          technical data without a license.

  (d)     Contracting Under this Grant
          ---------------------------- 

          It is the responsibility of the Grantee to obtain from its
     contractors hereunder technical data and rights therein, on behalf of the
     Government, necessary to fulfill the Grantee's obligations to the
     Government with respect to such data.  In the event of refusal by a
     contractor hereunder to accept an article affording the Government such
     rights, the Grantee shall:

     (1)  Promptly submit written notice to the Contracting Officer setting
          forth reasons for said contractor refusal and other pertinent
          information which may expedite disposition of the matter; and

     (2)  Not proceed with said contract without the written authorization of
          the Contracting Officer.

     Requirements" article in this grant or any provision of this grant
     specifying the delivery of technical data, the Grantee may withhold
     proprietary data from delivery, provided that the Grantee furnishes in
     lieu of any such proprietary data so withheld technical data disclosing
     the source, size, configuration, mating and attachment characteristics,
     functional characteristics and performance requirements ("Form, Fit and
     Function" data, e.g., specification control drawings, catalog sheets,
     envelope drawings, etc.) or a general description of such proprietary data
     where "Form, Fit and Function" data are not applicable.  The Government
     shall acquire no rights to any proprietary data so withheld except that
     such data shall be subject to the "inspection rights" provisions of
     paragraph (f), and, if included, the "limited rights in proprietary data"
     provisions of paragraph (g) and the "Grantee licensing" provisions or
     paragraph (h).

  (f)     Inspection Rights
          -----------------

     of proprietary data which are not subject to this paragraph, the
     Contracting Officer's representatives, at all reasonable times up to three
     (3) years after final payment under this grant, may inspect at the
     Grantee's facility any proprietary data withheld under paragraph (e) and
     not furnished under paragraph (g), if included, for the purposes of
     verifying that such data properly fell within the withholding provision of
     paragraph (e), or for evaluating work performance.

  ARTICLE 7.  RIGHTS TO PROPOSAL DATA

  It is agreed that as a condition of the award of this grant or modification
  thereto, and notwithstanding the provisions of any notice appearing on the
  proposal(s), the Government shall have the right to use, duplicate, and
  disclose and have others to do so for any purpose whatsoever, the technical
  data contained in the proposal(s) upon which this grant or modification is
  based.

A.  Statement of Substantial Involvement
    ------------------------------------
 
  The U.S. Department of Energy (hereinafter "DOE") and Collaborative Research
  Division, Collaborative Research, Inc. (hereinafter referred to as CRD)
  hereby enter into a Cooperative Agreement ("Agreement") for the purpose of
  conducting a three-year, mutually agreeable research program entitled
  "Microbial Genome Sequencing."

  This Agreement supports the application of a random shotgun-based multiplex
  sequencing strategy to the genome of a thermophilic archaebacterium,
  Methanobacterium thermoautotrophicum, and other program-relevant bacteria to
  be determined at a later date.  The project will enhance the knowledge and
  understanding of microbial genomes, contribute to DOE goals within the
  Microbial Genome Initiative, and provide a beneficial resource for the
  scientific and technical community.

  The following statements describe the anticipated substantial involvement
  between DOE and CRD, under the Cooperative Agreement awards.

  DOE ROLES AND RESPONSIBILITIES:  The DOE will provide programmatic direction
  and evaluation, through normal project monitoring, technical review, and peer
  review, and also through the creation of and participation on a Microbial
  Genome Advisory Board (hereinafter referred to as the MGAB).  Through its
  participation on the MGAB, the DOE will be involved with selection of strains
  for sequencing and the DOE will have responsibility for final approval of all
  strains selected.  Also, through its participation on the MGAB, the DOE will
  provide evaluation and review of technical and scientific reports; however,
  final content of all reports, including the annual progress report, is the
  responsibility of the CRD.  The DOE will conduct an annual on-site review of
  all project activities, for the purpose of providing input for future
  programmatic direction of the project; as necessary, the DOE will also review
  cognizant financial reports.

  PARTICIPANT ROLES AND RESPONSIBILITIES:  The CRD shall provide all personnel,
  facilities, equipment, supplies, and services, and otherwise do all things
  necessary for, or incident to, conducting the research project as set forth
  in the application dated April 21, 1994.  CRD is responsible for the overall
  management of effort necessary for timely and professional execution of the
  project work, and for coordination of the effort with other Microbial Genome
  Initiative investigators, in conjunction with direction and guidance from the
  MGAB and DOE.  It is also incumbent on CRD to make publicly available all
  microbial genome map and sequence data within six months after the data are
  obtained; data should be placed into public community databases, when
  possible.  Sequence data must be submitted to Genome Sequence Data Base
  (GSDB), GenBank, or any appropriate site that processes sequence entries for
  international distribution.

  The substantial involvement by the DOE under this Agreement will remain in
  effect for the term of the Cooperative Agreement award unless otherwise
  amended.  Moreover, this statement of substantial involvement by the DOE does
  not increase the DOE's liability under the Agreement award.

B.  Technical Direction and Surveillance
    ------------------------------------

     (1)  The work to be performed by the Participant under this Cooperative
          Agreement is subject to the surveillance and written Technical
          Direction of a "DOE Project Officer", identified in block 11 of the
          face page.  The term "Technical Direction" is defined to include,
          without limitation, the following:

          (a)  Directions to the Participant which redirects the work effort,
               shift work emphasis between work areas or tasks, require pursuit
               of certain lines of inquiry, fill in details or otherwise
               provide technical guidance to the Participant in order to
               accomplish the tasks and requirements stated in the Statement of
               Work as contained in the Agreement.


                                      -37-
<PAGE>   39

     (b)  Provision of information to the participant which assists in the
          interpretation of drawings, specifications or technical portions of
          the Statement of Work as contained in the Agreement.

     (c)  Review and, where required by the Cooperative Agreement, approval of
          technical reports, drawings, specifications or technical information
          to be delivered by the Participant to DOE under the Cooperative
          Agreement.

     (2)  Technical direction and management surveillance shall not impose
          tasks or requirements upon the Participant additional to or different
          from the tasks and requirements stated in the Statement of Work, of
          this Agreement.  The Technical Direction to be valid:

          (a)  Must be issued in writing consistent with the tasks and
               requirements stated in the Statement of Work of this Agreement;
               and

          (b)  May not:

               1    constitute an assignment of additional work outside the
                    task requirements stated in the Statement of Work of this
                    Agreement;

               2    in any manner cause an increase or decrease in the total
                    estimated project cost or the time required for project
                    performance;

               3    change any of the expressed terms, conditions or
                    specifications of the Cooperative Agreement; or

     (3)  The Participant shall proceed promptly with the performance of
          Technical Directions duly issued by the DOE Project Officer in the
          manner prescribed by paragraph (2) and which are within his authority
          under the provisions of paragraph (1); provided, however, that the
          Participant shall immediately cease the performance of any Technical
          Direction upon receipt of a written instruction to that effect from
          the Contracting Officer.

     (4)  If in the opinion of the Participant any Technical Direction issued
          by the DOE Project Officer is within one of the categories as defined
          in (2)(b) 1 through 4 above, the Participant shall not proceed but
          shall notify the Contracting Officer in writing within five working
          days after the receipt of any such Technical Direction and shall
          request the Contracting Officer to rescind such direction or mutually
          agree to modify the agreement accordingly.

     (5)  The only persons authorized to give Technical Direction to the
          Participant under this agreement are the Contracting Officer and any
          "DOE Project Officer" as listed in Block 11 of the NFAA.  Any action
          taken by the Participant in response to any direction given by any
          person other than the Contracting Officer shall not be binding upon
          the Government.

June 1, 1995

Genome Therapeutics Corp.
100 Beaver Street
Waltham, MA 02154
Mr. Fenel Eloi
Chief Financial Officer

Dear Mr. Eloi:

We are pleased to inform you that Silicon Valley Bank, a California chartered
bank (the "Lender") with its principal place of business at 3000 Lakeside
Drive, Santa Clara, CA 95054 and with a loan production office located in
Wellesley Office Park, 45 William Street, Suite 170 Wellesley, Massachusetts,
02181 doing business under the name "Silicon Valley East," has approved a
non-revolving line of credit in the amount of Five Hundred Thousand Dollars
($500,000.00) (the "Credit Facility") to Genome Therapeutics Corp. (the
"Borrower") to be used to finance the acquisition of equipment.  The foregoing
Commitment shall not become effective unless and until an executed copy of this
Agreement, together will all necessary accompanying documentation as well as
the Loan Fee described below has been returned to Lender no later than twenty
one (21) days from the date of the Agreement.  The Commitment shall be subject
to the following terms:

Borrowings under the Credit Facility will be permitted through December 1,
1995, with a payment schedule more particularly described in the accompanying
promissory note of even date (the "Note").

The Credit Facility shall bear an interest rate of one and one-half (1.500)
percentage points over Lender's Prime Rate.  Prime Rate means the rate from
time to time announced and made effective by Lender as its Prime Rate.
Borrower's interest rate shall change each time the Prime Rate changes.
Interest will be charged monthly in arrears and shall be calculated on a
360-day year.  Lender shall be authorized to debit Borrowers principal account
or any other account maintained by Borrower with Lender for any principal,
interest or fees associated with Borrowers facility with or without notice to
Borrower.  A facility fee in the amount of Two Thousand and 00/100 Dollars
($2,000.00) as well as any out-of-pocket expenses incurred by Lender in
connection with the establishment of the Credit Facility must be paid at the
time the documents are returned to Lender.

Borrowings under the Credit Facility shall be secured by the equipment financed
under the Credit Facility.

Borrower may request advances under the Note (each an "Advance" and
collectively, the "Advances") from Lender in an aggregate amount not to exceed
Five Hundred Thousand Dollars ($500,000.00). To evidence the Advances, Borrower
shall deliver to Lender, at the time of each advance request, an invoice for
the equipment to be purchased or the equipment which was purchased after
December 31, 1994.  The Advances shall be used only to purchase equipment and
shall not exceed One Hundred Percent (100%) of the invoice amount approved from
time to time by Lender, excluding taxes, shipping and installation expense.
Tenant Improvements may, however, comprise up to Twenty Thousand Dollars
($20,000.00) of the aggregate Advances.

Any Advances thereunder will be made only if, in the sole opinion of Lender,
there exists no default under any of the documentation executed by Borrower to
Lender, including this Agreement.  A default shall be further defined in the
Note.

                   minimum unrestricted cash of $1,200,000.00. In the event
                   Borrower's cash falls below $1,200,000.00, Borrower will
                   pledge to Lender a certificate of deposit (the "CD") in an
                   amount equal to 10% of the outstanding loan balance; in the
                   event minimum cash falls below $900,000.00, Borrower shall
                   increase the amount of the CD to an amount equal to 50% of
                   the outstanding balance of the Credit Facility; and if
                   Borrower's cash falls below $600,000.00, Borrower shall
                   increase the CD to an amount equal to 100% of the
                   outstanding balance of the Credit Facility.  Borrower shall
                   execute any additional documentation that Lender may require
                   in connection with the CD pledge.

              2.   MINIMUM EQUITY. Borrower shall maintain, on a quarterly

Borrower: Genome Therapeutics Corp.    Lender:  Silicon Valley Bank, a
          100 Beaver Street                     California-chartered bank doing

                                                02181

________________________________________________________________________________


Principal Amount: $500,000.00                         Date of Note: June 1, 1995


PROMISE TO PAY.  Genome Therapeutics Corp. ("Borrower") promises to pay to
Sillcon Valley Bank a California-chartered bank doing business as Silicon
Valley East ("Lender"), or order, in lawful money of the United States of
America, the principal amount of Five Hundred Thousand & 00/100 Dollars
($500,000.00) or so much as may be outstanding, together with interest on the
unpaid principal balance of each advance.  Interest shall be calculated from
the date of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in accordance with the following payment 
         schedule:

         The Draw Period shall begin as of this date and shall end on December
         1, 1995.  Borrower shall pay regular monthly payments of all accrued
         unpaid interest due as of each payment date, beginning July 1, 1995,
         with interest calculated on the unpaid principal balances at an
         interest rate as described below in the paragraph entitled "Interest
         Rate A", and all subsequent interest payments will be due on the same
         day of each month thereafter through December 1, 1995.  The
         outstanding principal balance on December 1, 1995 will be payable in
         thirty-six (36) even payments of principal plus interest due as of
         each payment date, beginning January 1, 1996, with interest calculated
         on the unpaid principal balances at an interest rate as described
         below in the paragraph entitled "Interest Rate B", and all subsequent
         payments of principal plus interest will be due on the same day of
         each month thereafter.  The final payment, due on December 1, 1998
         will be for all outstanding principal plus all accrued interest not
         yet paid.

Interest on this Note is computed on a 365/360 simple interest basis; that is,
by applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding.  Borrower will pay Lender
at Lender's address shown above or at such other place as Lender may designate
in writing.  Unless otherwise agreed or required by applicable law, payments
will be applied first to accrued unpaid interest, then to principal, and any
remaining amount to any unpaid collection costs and late charges.

INTEREST RATE A. From the date hereof through the end of the Draw Period, the
interest rate is subject to change from time to time based on changes in an
index which is Lender's Prime Rate (the "Index).  This is the rate Lender
charges, or would charge, on 90-day unsecured loans to the most creditworthy
corporate customers.  This rate may or may not be the lowest rate available
from Lender at any given time.  Lender will tell Borrower the current Index
rate upon Borrowers request.  Borrower understands that Lender may make loans
based on other rates as well.  The interest rate change will not occur more
often than each time the prime rate is adjusted by Silicon Valley Bank.  The
Index currently is 9.000% per annum.  The interest rate to be applied to the
unpaid principal balance of this Note through the end of the Draw Period will
be at a rate of 1.500 percentage points over the Index, resulting in an initial
rate of 10.500% per annum.  NOTICE: Under no circumstances will the interest
rate on this Note be more than the maximum rate allowed by applicable law.

INTEREST RATE B. Beginning as of the day following the end of the Draw Period,
the interest rate to be applied to the unpaid principal balance of this Note
will be fixed at a rate equal to 1.500 percentage points over the then current
Index.  NOTICE.  Under no circumstances will the interest rate on this Note be
more than the maximum rate allowed by applicable law.  Whenever increases occur
in the interest rate, Lender, at its option, may do one or more of the
following: (a) increase Borrower's payments to ensure Borrower's loan will pay
off by its original final maturity date, (b) increase Borrower's payments to
cover accruing interest, (c) 






                                     -11-



<PAGE>   13

increase the number of Borrower's payments, and
(d) continue Borrower's payments at the same amount and increase Borrowers
final payment

PREPAYMENT.  Borrower agrees that all loan fees and other prepaid finance
charges are earned fully as of the date of the loan and will not be subject to
refund upon early payment (whether voluntary or as a result of default), except
as otherwise required by law.  Except for the foregoing, Borrower may pay
without penalty all or a portion of the amount owed earlier than it is due.
Early payments will not, unless agreed to by Lender in writing, relieve
Borrower of Borrower's obligation to continue to make payments under the
payment schedule.  Rather, they will reduce the principal balance due and may
result in Borrower making fewer payments..

DEFAULT.  Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform
when any other term, obligation, covenant, or condition contained in this Note
or any agreement related to this Note, or in any other agreement or loan
Borrower has with Lender. (c) Borrower defaults under any loan, extension of
credit, security agreement, purchase or sales agreement, or any other
agreement, in favor of any other creditor or person that may materially affect
any of Borrowers property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents. (d) Any
representation or statement made or furnished to Lender by Borrower or on
Borrowers behalf is false or misleading in any material respect either now or
at the time made or furnished. (e) Borrower becomes insolvent, a receiver is
appointed for any part of Borrower's property, Borrower makes an assignment for
the benefit of creditors, or any proceeding is commenced either by Borrower or
against Borrower under any bankruptcy or insolvency laws. (f) Any creditor

tries to take any of Borrower's property on or in which Lender has a lien or
security interest. This includes a garnishment of any of Borrower's accounts
with Lender. (g) Any of the events described in this default section occurs
with respect to any guarantor of this Note. (h) A Material adverse change
occurs in Borrowers financial condition, or Lender believes the prospect of
payment or performance of the Indebtedness is impaired.

LENDER'S RIGHTS.  Upon default Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon default, including failure
to pay upon final maturity, Lender, at its option, may also, if permitted under
applicable law, do one or both of the following: (a)increase the variable
interest rate on this Note to 5.000 percentage points over the otherwise
effective interest rate and (b) add any unpaid accrued interest to principal
and such sum will bear interest therefrom until paid at the rate provided in
this Note (including any increased rate).  The interest rate will not exceed
the maximum rate permitted by applicable law.  Lender may hire or pay someone
else to help collect this Note if Borrower does not pay.  Borrower also will
pay Lender that amount.  This includes, subject to any limits under applicable
law, Lender's attorneys' fees and Lender's legal expenses whether or not there
is a lawsuit, including attorneys' fees and legal expenses for bankruptcy
proceedings (including efforts to modify or vacate any automatic stay or
injunction), appeals, and any anticipated post-judgment collection services.
If not prohibited be applicable law, Borrower also will pay any court costs, in
addition to all other sums provided by law.

LINE OF CREDIT.  This Note evidences a straight line of credit until December
1, 1995 Once the total amount of principal has been advanced, Borrower is not
entitled to further loan advances.  Advances under this Note, as well as
directions for payment from Borrower's accounts, may be requested orally or in
writing by Borrower or by an authorized person.  Lender may, but need not
require that all oral requests be confirmed in writing.  Borrower agrees to be
liable for all sums either (a) advanced in accordance with the instructions of
an authorized person or (b) credited to any of Borrower's accounts with Lender.
The unpaid principal balance owing on this Note at any time may be evidenced by
endorsements on this Note or by Lender's internal records, including daily
computer print-outs.  Lender will have no obligation to advance funds under
this Note if: (a) Borrower or any guarantor is in default under the terms of
this Note or any agreement that Borrower or any guarantor has with Lender,
including any agreement made in connection with the signing of this Note; (b)
Borrower or any guarantor ceases doing business or is insolvent; (c) any
guarantor seeks, claims or otherwise attempts to limit, modify or revoke such
guarantor's guarantee of this Note or any other loan with Lender; or (d)
Borrower has applied funds provided pursuant to this Note for purposes other
than those authorized by Lender.

ADVANCE RATE.  At any time from the date hereof through the end of the Draw
Period, Borrower may request advances (each an "Advance" and collectively, the
"Advances") from Lender in an aggregate amount not to exceed the principal
amount of the Note.  To evidence the Advances, Borrower shall deliver to
Lender, at the time of each advance request, an invoice for the equipment to be
purchased or equipment purchased after December 31, 1994.  The Advances shall
be used to purchase equipment shall not exceed One Hundred Percent (100%) of
the invoice amount approved from time to time by Lender, excluding taxes,
shipping and installation expense.  Tenant Improvements may, however, comprise
up to the aggregate of $20,000.00 in Advances, based upon 100% of the invoice
amount for tenant improvements made after December 31, 1994.

LETTER AGREEMENT.  This Note is subject to and shall be governed by all the
terms and conditions of the Letter Agreement dated June 1, 1995, as such
agreement may be amended from time to time, between Borrower and Lender, which
Letter Agreement is incorporated herein by reference.

PAYMENT OF LOAN FEE.  Borrower shall pay to Lender a fee in the amount of Two
Thousand and 00/100 Dollars ($2,000.00) plus all out-of-pocket expenses.

Lender, including, without limitation, Account Number _______________ for
payments of principal and interest due on the loan and any other obligations
owing by Borrower to Lender.  Lender will notify Borrower of all debits which
Lender makes against Borrower's accounts.  Any such debits against Borrower's
accounts in no way shall be deemed a set-off.

GENERAL PROVISIONS.  Lender may delay or forgo enforcing any of its rights or
remedies under this Note without losing them.  Borrower and any other person
who signs, guarantees or endorses this Note, to the extent allowed by law,
waive any applicable statute of limitations, presentment, demand for payment,

    any law or agreement governing Grantor or to which Grantor is a party, and 
    its certificate or articles of incorporation and bylaws do not prohibit
    any term or condition of this Agreement.

    ENFORCEABILITY OF COLLATERAL. To the extent the Collateral consists of
    accounts, chattel paper, or general intangibles, the Collateral is
    enforceable in accordance with its terms, is genuine, and complies with
    applicable laws concerning form, content and manner of preparation and
    execution, and all persons appearing to be obligated on the Collateral have
    authority and capacity to contract and are in act obligated as they appear
    to be on the Collateral.

and Collateral locations relating to Grantor's operations, including without
limitation the following: (a) all real property owned or being purchased by
Grantor; (b) all real property being rented or leased by Grantor; (c) all
storage facilities owned, rented, leased, or being used by Grantor; and (d) all
other properties where Collateral is or may be located.  Except in the ordinary
course of its business, Grantor shall not remove the Collateral from its
existing locations without the prior written consent of Lender.

REMOVAL OF COLLATERAL.  Grantor shall keep the Collateral (or to the extent the
Collateral consists of intangible property such as accounts, the records
concerning the Collateral) at Grantor's address shown above, or at such other
locations as are acceptable to Lender.  Except in the ordinary course of its
business, including the sales of inventory, Grantor shall not remove the
Collateral from its existing locations without the prior written consent of
Lender.  To the extent that the Collateral consists of vehicles, or other
titled property, Grantor shall not take or permit any action which would
require application for certificates of title for the vehicles outside the
Commonwealth of Massachusetts, without the prior written consent of Lender.

TRANSACTIONS INVOLVING COLLATERAL.  Except for inventory sold or accounts
collected in the ordinary course of Grantor's business, Grantor shall not sell,
offer to sell, or otherwise transfer or dispose of the Collateral.  While
Grantor is not in default under this Agreement, Grantor may sell inventory, but
only in the ordinary course of its business and only to buyers who qualify as a
buyer in the ordinary course of business.  A sale in the ordinary course of
Grantors business does not Include a transfer in partial or total satisfaction
of a debt or any bulk sale.  Grantor shall not pledge, mortgage, encumber or
otherwise permit the Collateral to be subject to any lien, security interest,
encumbrance, or charge, other than the security interest provided for in this
Agreement, without the prior written consent of Lender.  This includes security
interests even if junior in right to the security interests granted under this
Agreement.  Unless waived by Lender, all proceeds from any disposition of the
Collateral (for whatever reason) shall be held in trust for Lender and shall
not be commingled with any other funds; provided however, this requirement
shall not constitute consent by Lender to any sale or other disposition.  Upon
receipt, Grantor shall immediately deliver any such proceeds to Lender.

TITLE.  Grantor represents and warrants to Lender that it holds good and
marketable title to the Collateral, free and clear of all liens and
encumbrances except for the lien of this Agreement.  No financing statement
covering any of the Collateral is on file in any public office other than those
which reflect the security interest created by this Agreement or to which
Lender has specifically consented.  Grantor shall defend Lender's rights in the
Collateral against the claims and demands of all other persons.

COLLATERAL SCHEDULES AND LOCATIONS.  Insofar as the Collateral consists of
inventory, Grantor shall deliver to Lender, as often as Lender shall require,
such lists, descriptions, and designations of such Collateral as Lender may
require to identify the nature, extent, and location of such Collateral.  Such
information shall be submitted for Grantor and each of its subsidiaries or
related companies.

MAINTENANCE AND INSPECTION OF COLLATERAL.  Grantor shall maintain all tangible
Collateral in good condition and repair.  Grantor will not commit or permit
damage to or destruction of the Collateral or any part of the Collateral.
Lender and its designated representatives and agents shall have the right at
all reasonable times to examine, inspect, and audit the Collateral wherever
located.  Grantor shall immediately notify Lender of all cases involving the
return, rejection, repossession, loss or damage of or to any Collateral; of any
request for credit or adjustment or of any other 

                                       -18-
<PAGE>   20

dispute arising with respect to the Collateral; and generally of all happenings
and events affecting the Collateral or the value or the amount of the
Collateral.

TAXES, ASSESSMENTS AND LIENS.  Grantor will pay when due all taxes, assessments
and liens upon the Collateral, its use or operation, upon this Agreement, upon
any promissory note or notes evidencing the Indebtedness, or upon any of the
other Related Documents.  Grantor may withhold any such payment or may elect to
contest any lien if Grantor is in good faith conducting an appropriate
proceeding to contest the obligation to pay and so long as Lender's interest in
the Collateral is not jeopardized in Lender's sole opinion.  If the Collateral
is subjected to a lien which is not discharged within fifteen (15) days,
Grantor shall deposit with Lender cash, a sufficient corporate surety bond or
other security satisfactory to Lender in an amount adequate to provide for the
discharge of the lien plus any interest, costs, attorneys' fees or other
charges that could accrue as a result of foreclosure or sale of the Collateral.
In any contest Grantor shall defend itself and Lender and shall satisfy any
final adverse judgment before enforcement against the Collateral.  Grantor
shall name Lender as an additional obligee under any surety bond furnished in
the contest proceedings.

COMPLIANCE WITH GOVERNMENTAL REQUIREMENTS.  Grantor shall comply promptly with
all laws, ordinances, rules and regulations of all governmental authorities,
now or hereafter in effect, applicable to the ownership, production,
disposition, or use of the Collateral.  Grantor may contest in good faith any
such law, ordinance or regulation and withhold compliance during any
proceeding, including appropriate appeals, so long as Lender's interest in the
Collateral, in Lender's opinion, is not jeopardized.

HAZARDOUS SUBSTANCES.  Grantor represents and warrants that the Collateral
never has been, and never will be so long as this Agreement remains a lien on
the Collateral, used for the generation, manufacture, storage, transportation,
treatment, disposal, release or threatened release of any hazardous waste or
substance, as those terms are defined in the Comprehensive Environmental
Response, Compensation, and Liability Act of 1980, as amended, 42 U.S.C.
Section 9601, el seq. ("CERCLA"), the Superfund Amendments and Reauthorization
Act of 1986, Pub.  L. No. 99-499 ("SARA"), the Hazardous Materials
Transportation Act, 49 U.S.C. Section 1801, et seq., the Resource Conservation
and Recovery Act, 49 U.S.C. Section 6901, et seq., or other applicable state or
Federal laws, rules, or regulations adopted pursuant to any of the foregoing.
The terms "hazardous waste" and "hazardous substance' shall also include,
without limitation, petroleum and petroleum by-products or any fraction thereof
and asbestos.  The representations and warranties contained herein are based on
Grantor's due diligence in investigating the Collateral for hazardous wastes
and substances.  Grantor hereby (a) releases and waives any future claims
against Lender for indemnity or contribution in the event Grantor becomes
liable for cleanup or other costs under any such laws, and (b) agrees to
indemnity and hold harmless Lender against any and all claims and losses
resulting from a breach of this provision of this Agreement.  This obligation
to Indemnify shall survive the payment of the Indebtedness and the satisfaction
of this Agreement.

MAINTENANCE OF CASUALTY INSURANCE.  Grantor shall procure and maintain all
risks insurance, including without limitation fire, theft and liability
coverage together with such other insurance as Lender may require with respect
to the Collateral, in form, amounts, coverages and basis reasonably acceptable
to Lender and issued by a company or companies reasonably acceptable to Lender.
Grantor, upon request of Lender, will deliver to Lender from time to time the
policies or certificates of insurance in form satisfactory to Lender, including
stipulations that coverages will not be cancelled or diminished without at
least ten (10) days' prior written notice to Lender and not including any
disclaimer of the insurer's liability for failure to give such a notice.  Each
insurance policy also shall include an endorsement providing that coverage in
favor of Lender will not be impaired in any way by any act, omission or default
of Grantor or any other person.  In connection with all policies covering
assets in which Lender holds or is offered a security interest, Grantor will
provide Lender with such loss payable or other endorsements as Lender may
require.  If Grantor at any time fails to obtain or maintain any insurance as
required under this Agreement, Lender may (but shall not be obligated to)
obtain such insurance as Lender deems appropriate, including if it so chooses
"single interest insurance," which will cover only Lender's interest in the
Collateral.

                                       -19-
<PAGE>   21

APPLICATION OF INSURANCE PROCEEDS.  Grantor shall promptly notify Lender of any
loss or damage to the Collateral.  Lender may make proof of loss if Grantor
fails to do so within fifteen (15) days of the casualty.  All proceeds of any
insurance on the Collateral, including accrued proceeds thereon, shall be held
by Lender as part of the Collateral.  If Lender consents to repair or
replacement of the damaged or destroyed Collateral, Lender shall, upon
satisfactory proof of expenditure, pay or reimburse Grantor from the proceeds
for the reasonable cost of repair or restoration.  If Lender does not consent
to repair or replacement of the Collateral, Lender shall retain a sufficient
amount of the proceeds to pay all of the Indebtedness, and shall pay the
balance to Grantor.  Any proceeds which have not been disbursed within six (6)
months after their receipt and

                                  (Continued)
- -------------------------------------------------------------------------------


which Grantor has not committed to the repair or restoration of the Collateral
shall be used to prepay the Indebtedness.

INSURANCE RESERVES.  Lender may require Grantor to maintain with Lender reserves
for payment of insurance premiums, which reserves shall be created by monthly
payments from Grantor of a sum estimated by Lender to be sufficient to produce,
at least fifteen (15) days before the premium due date, amounts at least equal
to the insurance premiums to be paid.  If fifteen (15) days before payment is
due, the reserve funds are insufficient, Grantor shall upon demand pay any
deficiency to Lender.  The reserve funds shall be held by Lender as a general
deposit and shall constitute a non-interest-bearing account which Lender may
satisfy by payment of the insurance premiums required to be paid by Grantor as
they become due.  Lender does not hold the reserve funds in trust for Grantor,
and Lender is not the agent of Grantor for payment of the insurance premiums
required to be paid by Grantor.  The responsibility for the payment of premiums
shall remain Grantor's sole responsibility.


INSURANCE REPORTS.  Grantor, upon request of Lender, shall furnish to Lender
reports on each existing policy of insurance showing such information as Lender
may reasonably request including the following: (a) the name of the insurer, (b)
the risks insured; (c) the amount of the policy; (d) the property insured; (e)
the then current value on the basis of which insurance has been obtained and the
manner of determining that value; and (f) the expiration date of the policy.  In
addition, Grantor shall upon request by Lender (however not more often than
annually) have an independent appraiser satisfactory to Lender determine, as
applicable, the cash value or replacement cost of the Collateral.


GRANTOR'S RIGHT TO POSSESSION.  Until default, Grantor may have possession of
the tangible personal property and beneficial use of all the Collateral and may
use it in any lawful manner not inconsistent with this Agreement or the Related
Documents, provided that Grantor's right to possession and beneficial use shall
not apply to any Collateral where possession of the Collateral by Lender is
required by law to perfect Lender's security interest in such Collateral.  If
Lender at any time has possession of any Collateral, whether before or after an
Event of Default, Lender shall be deemed to have exercised reasonable care in
the custody and preservation of the Collateral if Lender takes such action for
that purpose as Grantor shall request or as Lender, in Lender's sole
discretion, shall deem appropriate under the circumstances, but failure to
honor any request by Grantor shall not of itself be deemed to be a failure to
exercise reasonable care.  Lender shall not be required to take any steps
necessary to preserve any rights in the Collateral against prior parties, nor
to protect,  preserve or maintain any security interest given to secure the
Indebtedness.

EXPENDITURES BY LENDER.  If not discharged or paid when due, Lender may (but
shall not be obligated to) discharge or pay any amounts required to be
discharged or paid by Grantor under this Agreement, including without
limitation all taxes, liens, security interests, encumbrances, and other
claims, at any time levied or placed on the Collateral.  Lender also may (but
shall not be obligated to) pay all costs for insuring, maintaining and
preserving the Collateral.  All such expenditures incurred or paid by Lender
for such purposes will then bear interest at the rate charged under the Note
from the date incurred or paid by Lender to the date of repayment by Grantor.
All such expenses shall become a part of the Indebtedness and, at Lender's
option, will (a) be payable on demand, (b) be added to the balance of the Note
and be apportioned among and be payable with any installment payments to become
due during either (i) the term of any applicable insurance policy or (ii) the
remaining term of the Note, or (c) be treated as a balloon payment which will
be due and payable at the Note's maturity.  This Agreement also will secure
payment 

                                       -21-
<PAGE>   23

of these amounts.  Such right shall be in addition to all other rights
and remedies to which Lender may be entitled upon the occurrence of an Event of
Default.

EVENTS OF DEFAULT.  Each of the following shall constitute an Event of Default
under this Agreement:

    DEFAULT ON INDEBTEDNESS.  Failure of Grantor to make any payment when due on
    the Indebtedness.

    OTHER DEFAULTS. Failure of Grantor to comply with or to perform any other
    term, obligation, covenant or condition contained in this Agreement or in
    any of the Related Documents or in any other agreement between Lender and
    Grantor.

    INSOLVENCY. The dissolution or termination of Grantor's existence as a going
    business, the insolvency of Grantor, the appointment of a receiver for any
    part of Grantor's property, any assignment for the benefit of creditors, any
    type of creditor workout, or the commencement of any proceeding under any
    bankruptcy or insolvency laws by or against Grantor.

    CREDITOR OR FORFEITURE PROCEEDINGS. Commencement of foreclosure or
    forfeiture proceedings, whether by judicial proceeding, self-help,
    repossession or any other method, by any creditor of Grantor or by any
    governmental agency against the Collateral or any other collateral securing
    the Indebtedness. This includes a garnishment of any of Grantors deposit
    accounts with Lender. 

    EVENTS AFFECTING GUARANTOR. Any of the preceding events occurs with 
    respect to any Guarantor of any of the Indebtedness or such Guarantor dies 
    or becomes incompetent.

    ADVERSE CHANGE. A material adverse change occurs in Grantor's financial
    condition, or Lender believes the prospect of payment or performance of the
    Indebtedness is impaired.

RIGHTS AND REMEDIES ON DEFAULT. If an Event of Default occurs under this
Agreement, at any time thereafter, Lender shall have all the rights of a
secured party under the Massachusetts Uniform Commercial Code. In addition and
without limitation, Lender may exercise any one or more of the following rights
and remedies:

    ACCELERATE INDEBTEDNESS. Lender may declare the entire Indebtedness,
    including any prepayment penalty which Grantor would be required to pay,
    immediately due and payable, without notice.

    ASSEMBLE COLLATERAL. Lender may require Grantor to deliver to Lender all or
    any portion of the Collateral and any and all certificates of title and
    other documents relating to the Collateral. Lender may require Grantor to
    assemble the Collateral and make it available to Lender at a place to be
    designated by Lender. Lender also shall have full power to enter upon the
    property of Grantor to take possession of and remove the Collateral. If the
    Collateral contains other goods not covered by this Agreement at the time of
    repossession, Grantor agrees Lender may take such other goods, provided that
    Lender makes reasonable efforts to return them to Grantor after
    repossession.

    SELL THE COLLATERAL. Lender shall have full power to sell, lease, transfer,
    or otherwise deal with the Collateral or proceeds thereof in its own name
    or that of Grantor. Lender may sell the Collateral at public auction or
    private sale. Unless the Collateral threatens to decline speedily in value
    or is of a type customarily sold on a recognized market, Lender will give
    Grantor reasonable notice of the time after which any private sale or any
    other intended disposition of the Collateral is to be made. The requirements
    of reasonable notice shall be met if such notice is given at least ten (10)
    days before the time of the sale or disposition. All expenses relating to
    the disposition of the Collateral, including without limitation the expenses
    of retaking, holding, insuring, preparing for sale and selling the
    Collateral, shall become a part of the Indebtedness secured by this


                                       -22-
<PAGE>   24

    Agreement and shall be payable on demand, with interest at the Note rate
    from date of expenditure until repaid.

    APPOINT RECEIVER. To the extent permitted by applicable law, Lender shall
    have the following rights and remedies regarding the appointment of a
    receiver: (a) Lender may have a receiver appointed as a matter of right, (b)
    the receiver may be an employee of Lender and may serve without bond, and
    (c) all fees of the receiver and his or her attorney shall become part of
    the Indebtedness secured by this Agreement and shall be payable on demand,
    with interest at the Note rate from date of expenditure until repaid.

    COLLECT REVENUES, Apply Accounts. Lender, either itself or through a
    receiver, may collect the payments, rents, income, and revenues from the
    Collateral. Lender may at any time in its discretion transfer any Collateral
    into its own name or that of its nominee and receive the payments, rents,
    income, and revenues therefrom and hold the same as security for the
    Indebtedness or apply it to payment of the Indebtedness in such order of
    preference as Lender may determine. Insofar as the Collateral consists of
    accounts, general intangibles, insurance policies, instruments, chattel
    paper, chooses in action, or similar property, Lender may demand, collect,
    receipt for, settle, compromise, adjust, sue for, foreclose, or

                                       -23-

                                  (Continued)
- --------------------------------------------------------------------------------

realize on the Collateral as Lender may determine, whether or not Indebtedness
or Collateral is then due.  For these purposes, Lender may, on behalf of and in
the name of Grantor, receive, open and dispose of mail addressed to Grantor,
change any address to which mail and payments are to be sent; and endorse
notes, checks, drafts, money orders, documents of title, instruments and items
pertaining to payment, shipment, or storage of any Collateral.  To facilitate
collection, Lender may notify account debtors and obligers on any Collateral to
make payments directly to Lender.

    OBTAIN DEFICIENCY.  If Lender chooses to sell any or all of the Collateral,
    Lender may obtain a judgment against Grantor for any deficiency remaining on
    the Indebtedness due to Lender after application of all amounts received
    from the exercise of the rights provided in this Agreement.  Grantor shall
    be liable for a deficiency even if the transaction described in this
    subsection is a sale of accounts or chattel paper.

    OTHER RIGHTS AND REMEDIES.  Lender shall have all the rights and remedies of
    a secured creditor under the provisions of the Uniform Commercial Code, as
    may be amended from time to time.  In addition, Lender shall have and may
    exercise any or all other rights and remedies it may have available at law,
    in equity, or otherwise.

    CUMULATIVE REMEDIES.  All of Lender's rights and remedies, whether evidenced
    by this Agreement or the Related Documents or by any other writing, shall be
    cumulative and may be exercised singularly or concurrently.  Election by
    Lender to pursue any remedy shall not exclude pursuit of any other remedy,
    and an election to make expenditures or to take action to perform an
    obligation of Grantor under this Agreement, after Grantor's failure to
    perform, shall not affect Lender's right to declare a default and to
    exercise its remedies.

MISCELLANEOUS PROVISIONS.  The following miscellaneous provisions are a part of
this Agreement:

    AMENDMENTS.  This Agreement, together with any Related Documents,
    constitutes the entire understanding and agreement of the parties as to the
    matters set forth in this Agreement.  No alteration of or amendment to this
    Agreement shall be effective unless given in writing and signed by the party
    or parties sought to be charged or bound by the alteration or amendment.

    ATTORNEYS' FEES; EXPENSES.  Grantor agrees to pay upon demand all of
    Lender's costs and expenses, including attorneys' fees and Lender's legal
    expenses, incurred in connection with the enforcement of this Agreement.
    Lender may pay someone else to help enforce this Agreement, and Grantor
    shall pay the costs and expenses of such enforcement. Costs and expenses
    include Lenders attorneys' fees and legal expenses whether or not there is a
    lawsuit, including attorneys' fees and legal expenses for bankruptcy
    proceedings (and including efforts to modify or vacate any automatic stay or
    injunction), appeals, and any anticipated post-judgment collection services.
    Grantor also shall pay all court costs and such additional fees as may be
    directed by the court.

    CAPTION HEADINGS.  Caption headings in this Agreement are for convenience
    purposes only and are not to be used to interpret or define the provisions
    of this Agreement.

                                       -24-
<PAGE>   26


MULTIPLE PARTIES; CORPORATE AUTHORITY.  All obligations of Grantor under this
Agreement shall be joint and several, and all references to Grantor shall mean
each and every Grantor.  This means that each of the Borrowers signing below is
responsible for all obligations in this Agreement.

NOTICES.  All notices required to be given under this Agreement shall be given
in writing, may be sent by telefacsimilie, and shall be effective when actually
delivered or when deposited with a nationally recognized overnight courier or
deposited in the United States mail, first class, postage prepaid, addressed to
the party to whom the notice is to be given at the address shown above.  Any
party may change its address for notices under this Agreement by giving formal
written notice to the other parties, specifying that the purpose of the notice
is to change the party's address.  To the extent permitted by applicable law,
if there is more than one Grantor, notice to any Grantor will constitute notice
to all Grantors.  For notice purposes, Grantor agrees to keep Lender informed
at all times of Grantor's current address(es).

POWER OF ATTORNEY.  Grantor hereby appoints Lender as its true and lawful
attorney-in-fact, irrevocably, with full power of substitution to do the
following (a) to demand, collect, receive, receipt for, sue and recover all
sums of money or other property which may now or hereafter become due, owing or
payable from the Collateral; (b) to execute, sign and endorse any and all
claims, instruments, receipts, checks, drafts or warrants issued in payment for
the Collateral; (c) to settle or compromise any and all claims arising under
the Collateral, and, in the place and stead of Grantor, to execute and deliver
its release and settlement for the claim; and (d) to file any claim or claims
or to take any action or institute or take part in any proceedings, either in
its own name or in the name of Grantor, or otherwise, which in the discretion
of Lender may seem to be necessary or advisable.  This power is given as
security for the Indebtedness, and the authority hereby conferred is and shall
be irrevocable and shall remain in full force and effect until renounced by
Lender.

SEVERABILITY.  If a court of competent jurisdiction finds any provision of this
Agreement to be invalid or unenforceable as to any person or circumstance, such
finding shall not render that provision invalid or unenforceable as to any
other persons or circumstances.  If feasible, any such offending provision
shall be deemed to be modified to be within the limits of enforceability or
validity; however, if the offending provision cannot be so modified, it shall
be stricken and all other provisions of this Agreement in all other respects
shall remain valid and enforceable.

SUCCESSOR INTERESTS.  Subject to the limitations set forth above on transfer of
the Collateral, this Agreement shall be binding upon and inure to the benefit
of the parties, their successors and assigns.

WAIVER.  Lender shall not be deemed to have waived any rights under this
Agreement unless such waiver is given in writing and signed by Lender.  No
delay or omission on the part of Lender in exercising any right shall operate
as a waiver of such right or any other right.  A waiver by Lender of a
provision of this Agreement shall not prejudice or constitute a waiver of
Lender's right otherwise to demand strict compliance with that provision or any
other provision of this Agreement.  No prior waiver by Lender, nor any course
of dealing between Lender and Grantor, shall constitute a waiver of any of
Lender's rights or of any of Grantor's obligations as to any future
transactions.  Whenever the consent of Lender is required under this Agreement,
the granting of such consent by Lender in any instance shall not constitute
continuing consent to subsequent instances where such consent is required and
in all cases such consent may be granted or withheld in the sole discretion of
Lender.

ADDITIONAL PROVISION.  If any law is passed that requires additional action on
the part of Lender, Grantor shall fully cooperate with Lender in complying with
the law and accordingly, shall reimburse Lender for all costs and expenses
which Lender incurs to comply with the law.

REQUEST TO HOLD.  Borrower acknowledges and agrees that Lender may place a hold
on any deposit account pledged to Lender as Collateral for the Note.

                                                 Date of Note: November 13, 1995

PROMISE TO PAY.  Genome Therapeutics Corporation ("Borrower") promises to pay
to SILICON VALLEY BANK, a California-chartered bank, a California bank with a
loan production office in Wellesley, Massachusetts ("Lender"), or order, in
lawful money of the United States of America, the principal amount of One
Million Five Hundred Thousand & 00/100 Dollars ($1,500,000.00) or so much as
may be outstanding, together with interest on the unpaid outstanding principal
balance of each advance.  Interest shall be calculated from the date of each
advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in accordance with the following payment
         schedule:

         The Draw Period shall begin as of this date and shall end on August
         31, 1996 (the "Draw Period").  Each Incremental Draw (as defined
         below) shall be payable in thirty-six (36) even payments of principal
         plus interest due beginning one month following the date the
         Incremental Draw is made, and all subsequent payments of principal
         plus interest will be due on the same day of each month thereafter.
         The final payment, due on August 31, 1999, or thirty-six (36) months
         following the date of the final Incremental Draw, whichever shall
         first occur, will be for all outstanding principal plus all accrued
         interest not yet paid.

Interest on this Note is computed on 365/380 simple interest basis; that is, by
applying the ratio of the annual interest rate over a year  of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding.  Borrower will pay Lender
at 3000 Lakeside Drive, Santa Clara, California 95054.  Unless otherwise agreed
or required by applicable law, payments will be applied first to accrued unpaid
interest, then to principal, and any remaining amount to any unpaid collection
costs and late charges.

VARIABLE INTEREST RATE.  The interest rate on this Note is subject to change
from time to time based on changes in an index which is Lender's Prime Rate
(the "Index").  This is the rate Lender charges, or would charge, on 90-day
unsecured loans to the most creditworthy corporate customers.  This rate may or
may not be the lowest rate available from Lender at any given time.  Lender
will tell Borrower the current Index rate upon Borrower's request.  Borrower
understands that Lender may make loans based on other rates as well.  The
interest rate change will not occur more often than each time the prime rate is
adjusted by Silicon Valley Bank.  The Index currently is 8.750% per annum.  The
interest rate to be applied to the unpaid principal balance of this Note will
be at a rate of 1.000 percentage point over the Index, resulting in an initial
rate of 9.750% per annum.  NOTICE:  Under no circumstances will the interest
rate on this Note be more than the maximum rate allowed by applicable law.

PREPAYMENT.  Borrower agrees that all loan fees and other prepaid finance
charges are earned fully as of the date of the loan and will not be subject to
refund upon early payment (whether voluntary or as a result of default), except
as otherwise required by law.  Except for the foregoing, Borrower may pay
without penalty all or a portion of the amount owed earlier than it is due.
Early payments will not, unless agreed to by Lender in writing, relieve
Borrower 


                                      -4-
<PAGE>   36

of Borrower's obligation to continue to make payments of accrued
unpaid interest.  Rather, they will reduce the principal balance due.

DEFAULT.  Borrower will be in default if any of the following happens:  (a)
Borrower fails to make any payment when due.  (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform
when due any other term, obligation, covenant, or condition contained in this
Note or any agreement related to this Note, or in any other agreement or loan
Borrower has with Lender.  (c)  Borrower defaults under any loan, extension of
credit, security agreement, purchase or sales agreement, or any other

any of Borrower's property or Borrower's ability to repay this Note or perform
Borrower's obligations under this Note or any of the Related Documents.  (d)

LENDER'S RIGHTS.  Upon default, Lender may declare the entire unpaid principal
balance of this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount.  Upon default, including
failure to pay upon final maturity, Lender, at its option, may also, if
permitted under applicable law, do one or both of the following:  (a) increase
the variable interest rate on this Note to 6.000 percentage points over the
Index, and (b) add any unpaid accrued interest to principal and such sum will
bear interest therefrom until paid at the rate provided in this Note (including
any increased rate).  The interest rate will not exceed the maximum rate
permitted by applicable law.  Lender may hire or pay someone else to help
collect this Note if Borrower does not pay.  Borrower also will pay Lender that
amount.  This includes, subject to any limits under applicable law, Lender's
attorneys' fees and Lender's legal expenses whether or not there is a lawsuit,
including attorneys' fees and legal expenses for bankruptcy proceedings
(including efforts to modify or vacate any automatic stay or injunction),
appeals, and any anticipated post-judgment collection services.  If not
prohibited by applicable law, Borrower also will pay any court costs, in
addition to all other sums provided by law.

LINE OF CREDIT.  This Note evidences a straight line of credit until AUGUST 31,
1996.  /s/ FME  Once the total amount of principal has been advanced, Borrower
is not entitled to further loan advances.  Advances under this Note, as well as
directions for payment from Borrower's accounts, may be requested orally or in
writing by Borrower or by an authorized person.  Lender may, but need not,
require that all oral requests be confirmed in writing.  Borrower agrees to be
liable for all sums either:  (a) advanced in accordance with the instructions
of an authorized person or (b) credited to any of Borrower's accounts with
Lender.  The unpaid principal balance owing on this Note at any time may be
evidenced by endorsements on this Note or by Lender's internal records,
including daily computer print-outs.  Lender will have no obligation to advance
funds under this Note if:  (a) Borrower or any guarantor is in default under
the terms of this Note or any agreement that Borrower or any guarantor has with
Lender, including any agreement made in connection with the signing of this
Note; (b) Borrower or any guarantor ceases doing business or is insolvent; (c)
any guarantor seeks, claims or otherwise attempts to limit, modify or revoke
such guarantor's guarantee of this Note or any other loan with Lender; or (d)
Borrower has applied funds provided pursuant to this Note for purposes other
than those authorized by Lender.

REQUEST TO DEBIT ACCOUNTS.  Borrower will regularly deposit all funds received
from its business activities in accounts maintained by Borrower at Silicon
Valley Bank.  Borrower hereby requests and authorizes Lender to debit any of
Borrower's accounts with Lender, specifically, without limitation, Account

any other obligations owing by Borrower to Lender.  Lender will notify

advance request, an invoice(s) for the equipment, software, or tenant

person who signs, guarantees or endorses this Note, to the extent allowed by
law, waive presentment, demand for payment, protest and notice of dishonor.

stated in writing, no party who signs this Note, whether as maker, guarantor,
accommodation maker or endorser, shall be released from liability.  To the
extent permitted by applicable law, all such parties agree that Lender may
